1 1999-12-09 Greg J. Badros <gjb@cs.washington.edu>
3 * strports.h, strports.c (scm_eval_0str): Fix constness. Some
4 thanks to Dirk Hermann.
6 * gh_eval.c (gh_eval_str, gh_eval_file, gh_eval_str_with_catch,
7 gh_eval_str_with_standard_handler,
8 gh_eval_str_with_stack_saving_handler): Fix constness. Some
9 thanks to Dirk Hermann.
11 * gh_data.c (gh_str02scm): Fix constness.
13 * gh.h: Fix constness of prototypes for the above.
15 * vectors.c: Include "unif.h" to avoid a warning about missing
16 prototype for scm_uniform_element_size().
18 1999-12-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
20 * vectors.c (scm_vector_length, scm_vector_ref, scm_vector_set_x):
21 Turned into primitive generics.
23 1999-12-04 Gary Houston <ghouston@freewire.co.uk>
25 * ports.c (scm_port_closed_p): new procedure, implements
26 "port-closed?" suggested by Bernard Urban.
27 ports.h: added prototype, removed the SCM_P macros.
29 1999-11-30 Gary Houston <ghouston@freewire.co.uk>
31 * unif.h: added some comments, removed the SCM_P macros.
33 1999-11-29 Gary Houston <ghouston@freewire.co.uk>
35 * vports.c (sf_write): use scm_makfromstr, not scm_makfrom0str
36 (thanks to Daniel Skarda).
38 1999-11-22 Jim Blandy <jimb@savonarola.red-bean.com>
40 * gscm.c, gscm.h: Deleted. They were unused.
42 1999-11-20 Gary Houston <ghouston@freewire.co.uk>
44 * unif.c (scm_list_to_uniform_array): call
45 scm_dimensions_to_uniform_array with a third argument of
46 SCM_UNDEFINED instead of SCM_EOL.
48 1999-11-19 Gary Houston <ghouston@freewire.co.uk>
50 * the following changes allow guile to be built with the array
51 "module" omitted. some of this stuff is just tc7 type support,
52 which wouldn't be needed if uniform array types were converted
55 * tag.c (scm_utag_bvect ... scm_utag_cvect): don't define unless
57 (scm_tag): don't check array types unless HAVE_ARRAYS.
59 * sort.c (scm_restricted_vector_sort_x, scm_sorted_p):
60 remove the unused array types.
61 * (scm_stable_sort, scm_sort): don't support vectors if not
62 HAVE_ARRAYS. a bit excessive.
64 * random.c (vector_scale, vector_sum_squares,
65 scm_random_solid_sphere_x, scm_random_hollow_sphere_x,
66 scm_random_normal_vector_x): don't define unless HAVE_ARRAYS.
68 * gh_data.c (makvect, gh_chars2byvect, gh_shorts2svect,
69 gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect, gh_doubles2dvect,
70 gh_uniform_vector_length, gh_uniform_vector_ref):
71 don't define unless HAVE_ARRAYS.
72 (gh_scm2chars, gh_scm2shorts, gh_scm2longs, gh_scm2floats,
74 don't check vector types if not HAVE_ARRAYS.
76 * eq.c (scm_equal_p), eval.c (SCM_CEVAL), print.c (scm_iprin1),
77 gc.c (scm_gc_mark, scm_gc_sweep), objects.c (scm_class_of):
78 don't support the array types unless HAVE_ARRAYS is defined.
80 * tags.h: make nine tc7 types conditional on HAVE_ARRAYS.
82 * read.c (scm_lreadr): don't check for #* unless HAVE_ARRAYS is
83 defined (this should use read-hash-extend).
85 * ramap.c, unif.c: don't check whether ARRAYS is defined.
87 * vectors.c (scm_vector_set_length_x): moved here from unif.c. call
88 scm_uniform_element_size if HAVE_ARRAYS.
89 vectors.h: prototype too.
91 * unif.c (scm_uniform_element_size): new procedure.
93 * init.c (scm_boot_guile_1): don't call scm_init_ramap or
94 scm_init_unif unless HAVE_ARRAYS is defined.
96 * __scm.h: don't define ARRAYS.
98 * Makefile.am (EXTRA_libguile_la_SOURCES): unif.c and ramap.c
99 moved here from libguile_la_SOURCES.
101 1999-11-18 Gary Houston <ghouston@freewire.co.uk>
103 * socket.c (scm_htons, scm_ntohs, scm_htonl, scm_ntohl): new
104 functions for network data conversion.
106 * numbers.c (scm_num2long, scm_num2longlong):
107 throw out-of-range instead of wrong-type-arg if appropriate.
108 (scm_iint2str): handle -2^31 correctly.
109 (scm_num2long): handle -2^31 bignum correctly.
110 (scm_num2long_long): rewrite the bigdig case: basically copied
112 numbers.h: (SCM_BITSPERLONGLONG): deleted.
114 * unif.c (rapr1): use sprintf instead of intprint for unsigned
115 longs: intprint can't cope with large values.
117 * numbers.c (scm_num2ulong): check more consistently that the
118 input is not negative. if it is, throw out-of-range instead of
121 * ramap.c (scm_array_fill_int): don't limit fill to INUM for
122 uvect, ivect or llvect.
123 Check that fill doesn't overflow short uniform array.
125 * __scm.h: add another long to the definition of long_long and
128 * unif.c (scm_raprin1): use 'l' instead of "long_long" in the
129 print representation of llvect. read can't handle more than
131 (scm_dimensions_to_uniform_array): make "fill" an optional argument
132 instead of a rest argument.
134 * tags.h (scm_tc7_llvect): wasn't defined anywhere, so use the free
137 * __scm.h: don't mention LONGLONGS.
139 * unif.c, numbers.c, eq.c, gc.c, print.c, eval.c, ramap.c:
140 replace LONGLONGS with HAVE_LONG_LONGS as set by configure.
142 1999-11-17 Gary Houston <ghouston@freewire.co.uk>
144 * net_db.c (scm_inet_aton): throw errors using the misc-error key
145 instead of system-error. inet_aton doesn't set errno.
146 system-error isn't right in gethost either, since it's throwing
147 the value of h_errno instead of errno. so:
148 (scm_host_not_found_key, scm_try_again_key,
149 scm_no_recovery_key, scm_no_data_key): new error keys.
150 (scm_resolv_error): new procedure, use the new keys.
151 (scm_gethost): call scm_resolv_error not scm_syserror_msg.
153 1999-11-16 Gary Houston <ghouston@freewire.co.uk>
155 * error.c: (various): use scm_cons instead of scm_listify
156 to build short lists.
158 1999-11-03 Gary Houston <ghouston@freewire.co.uk>
160 * socket.c (scm_fill_sockaddr): zero the address structure before
161 use, in case it has a sin_len field and the OS doesn't like random
162 values (thanks to Bertrand Petit).
164 1999-10-26 Mark Galassi <rosalia@lanl.gov>
166 * gh.h, gh_data.c (gh_symbol2scm): changed gh_symbol2scm() to take
167 a const char * argument, upon suggestion from Lynn Winebarger.
169 1999-10-26 Gary Houston <ghouston@freewire.co.uk>
171 * strports.c (st_end_input): avoid dubious pointer arithmetic.
173 1999-10-24 Gary Houston <ghouston@freewire.co.uk>
175 * Move the responsibility for resetting port buffers from the
176 caller of the ptob seek procedure to the implementation. This
177 gives more control in general to the ptob seek: in particular the
178 change of 1999-10-20 can be made to work without breaking seek on
179 string ports. There's a comment in NEWS about upgrading port
182 * ports.c (scm_seek): don't reset the port buffers here.
184 * fports.c (fport_seek): reset the buffers, except for the
187 * strports.c (st_end_input): (bug fix): decrement pt->read_pos by
188 offset. check that it's not less than read_buf.
189 (st_seek): reset the buffers first, unless it's the 0 SEEK_CUR
190 case and currently reading.
192 1999-10-20 Gary Houston <ghouston@freewire.co.uk>
194 * ports.c (scm_seek): Add a special case for SEEK_CUR, offset 0,
195 so that unread chars are not needlessly discarded. (thanks to
198 1999-10-18 Gary Houston <ghouston@freewire.co.uk>
200 * fports.c (scm_fdes_to_port): always set rw_random if the fdes is
201 random access. rw_active needs to be maintained even for single
202 directional ports, otherwise scm_seek and probably other things are
203 broken. (thanks to Roland Orre).
205 * strports.c (scm_mkstrport): set rw_random to 1 unconditionally.
207 * ports.c (scm_add_to_port_table): initialise rw_random to 0.
209 * ports.h (scm_port): change the comments on rw_random and rw_active.
211 1999-10-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
213 * ioext.c: Added #include "feature.h".
215 These changes turns `delay' into a memoizing macro. This is
216 because it may be expanded before evaluation if it occurs at the
217 beginning of a body. (Thanks to Lauri Alanko.)
219 * eval.c, eval.h (scm_sym_delay): New global symbol.
221 * tags.h (SCM_IM_DELAY): New immediate symbol.
223 * print.c (scm_isymnames): Printed representation.
225 * eval.c (unmemocopy, SCM_CEVAL): Handle SCM_IM_DELAY.
226 (scm_m_delay): Turned into a memoizing macro.
228 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version.
230 1999-10-11 Jim Blandy <jimb@savonarola.red-bean.com>
232 * gh_data.c (gh_ints2scm, gh_doubles2scm): Make sure elements are
233 protected from GC while building the vector. (Thanks to Bernard
234 Urban and Greg Harvey.)
236 1999-10-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
238 * throw.c (handler_message): Display backtrace if backtraces
241 1999-10-05 Jim Blandy <jimb@savonarola.red-bean.com>
243 * Makefile.in, scmconfig.h.in: Deleted from CVS repository. Run
244 the autogen.sh script to create generated files like these.
246 * numbers.c (scm_string_to_number): Signal an error if radix is
247 less than two. (Thanks to Jorgen Schaefer.)
249 * print.c (scm_write, scm_display, scm_newline, scm_write_char):
250 Don't assume that the current output port is valid. Somebody
251 might close it. (Thanks to Bernard Urban.)
253 1999-10-02 Jim Blandy <jimb@zwingli.cygnus.com>
255 * scmconfig.h.in: Regenerated.
257 * Makefile.am (EXTRA_libguile_la_SOURCES): fix typo.
259 Mon Sep 27 17:15:14 1999 Greg J. Badros <gjb@cs.washington.edu>
261 * __scm.h: Fix a bunch of macros that were missing do-while(0)
264 * debug.c, eval.c: Fix buggy uses of SCM_ALLOW_INTS (missing
265 semicolon) exposed by the above change.
267 1999-09-27 Greg J. Badros <gjb@cs.washington.edu>
269 * stacks.c: Avoid compiler warning re: unitialized var.
271 * scmconfig.h.in: Added DEBUG_FREELIST
273 * pairs.h: Fix macro that was not do-while(0) sandwiched.
275 * gc.h, gc.c: Added scm_gc_set_debug_check_freelist_x,
278 1999-09-23 Gary Houston <ghouston@freewire.co.uk>
280 * ioext.c (scm_init_ioext): enable "i/o-extensions" feature here
281 instead of in scm_init_filesys.
283 * init.c (scm_boot_guile_1): don't call scm_init_posix or
284 scm_init_filesys unless HAVE_POSIX is defined.
285 don't call scm_init_netdb or scm_init_socket unless
286 HAVE_NETWORKING is defined.
288 * Makefile.am (EXTRA_libguile_la_SOURCES): filesys.c, posix.c,
289 net_db.c, socket.c: moved here from libguile_la_SOURCES.
291 1999-09-25 Jim Blandy <jimb@savonarola.red-bean.com>
293 * root.c (scm_make_root): Initialize all the fields of the new
294 root. GC could happen any time, you know. (Thanks to Greg
297 * numbers.c (scm_number_to_string): Signal an error if radix is
298 less than two. (Thanks to Jorgen Schaefer.)
300 * Makefile.am (EXTRA_libguile_la_SOURCES): Add memmove.c here,
301 so automake will actually generate rules for it.
302 * Makefile.in: Regenerated.
304 1999-09-21 Jim Blandy <jimb@savonarola.red-bean.com>
306 * backtrace.c: #include "_scm.h" before testing whether
307 HAVE_UNISTD_H is #defined.
309 1999-09-20 Jim Blandy <jimb@savonarola.red-bean.com>
311 * read.c (scm_read): Don't assume that scm_cur_inp is always open.
312 * ports.c (scm_read_char): Same.
313 * ioext.c (scm_read_line): Same.
314 (Thanks to Bernard Urban.)
316 1999-09-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
318 * vectors.c (scm_vector_move_right_x): Bugfix: Remove side effect
320 numbers.c: Removed #ifndef SCM_RECKLESS at places where type
321 checking may invoke a generic. (Thanks to Michael Livshin.)
323 * __scm.h (SCM_WTA_DISPATCH_0, SCM_GASSERT0): New macros.
325 * numbers.c (scm_max, scm_min, scm_sum, scm_difference,
326 scm_product, scm_divide): Bugfix: Don't pass SCM_UNDEFINED to the
327 generic function if the asubr is called with only one arg.
329 1999-09-20 Gary Houston <ghouston@freewire.co.uk>
331 * scmsigs.c (scm_sigaction): add SA_RESTART to flags only if
332 HAVE_RESTARTABLE_SYSCALLS.
333 (scm_init_scmsigs): use siginterrupt if it's available. not
334 everyone who has restartable syscalls has SA_RESTART it seems.
336 (scm_sigaction): use scm_num2long/scm_long2num when converting
337 SIG_DFL/SIG_IGN, in case it doesn't fit in an INUM. use
338 scm_integer_p to test the type.
340 1999-09-18 Gary Houston <ghouston@freewire.co.uk>
342 * _scm.h, scmsigs.c: replace HAVE_RESTARTS with
343 HAVE_RESTARTABLE_SYSCALLS.
345 * strports.c (scm_strport_to_string): create the string from
346 pt->read_buf instead of an expression that evaluates to the
349 * gdbint.c (gdb_print): don't just use SCM_CHARS to get a C string
350 from the port: the port's buffer may not be NUL terminated.
352 1999-09-16 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
354 * Makefile.am (.c.x): Added missing semicolon after `false'.
356 1999-09-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
358 * print.c (scm_iprin1): Turn `write' and `display' into
359 primitive generics and use their associated generic functions in
360 scm_iprin1 for GOOPS objects.
362 * backtrace.c: #include <unistd.h> if present.
364 1999-09-14 Jim Blandy <jimb@savonarola.red-bean.com>
366 * Makefile.am (.c.x): Don't create a subshell just to delete the
367 .x file and return false.
368 * Makefile.in: Regenerated.
370 1999-09-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
372 * feature.c (scm_create_hook): New function. Replaces
373 scm_make_named_hook which is now deprecated.
374 (scm_make_hook_with_name): New primitive.
375 (print_hook): Hooks now print in a fancy way.
377 1999-09-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
379 * __scm.h, backtrace.c, backtrace.h, debug.c, debug.h, dynl-dld.c,
380 dynwind.c, dynwind.h, eval.h, evalext.c, evalext.h, feature.c,
381 feature.h, hashtab.c, hashtab.h, objects.c, objects.h, print.c,
382 procs.c, procs.h, smob.c, smob.h, srcprop.c, strorder.c, struct.c,
383 struct.h: Updated copyright notices.
385 * srcprop.c (scm_source_property): Bugfix: Use SCM_NECONSP instead
386 of SCM_NCONSP. (Thanks to Greg Badros.)
388 * gsubr.c (scm_make_gsubr): Use scm_make_subr_opt for creation of
391 * eval.c, debug.h (SCM_BACKTRACE_WIDTH): New debug option: width.
393 * backtrace.c: Keep backtraces within specified width by
394 adaptively adjusting fancy printing parameters and cut output if
396 (scm_display_application): Check args.
398 1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
400 Change the name of the objects returned by OPENDIR from
401 "directory" to "directory stream". A predicate named "directory?"
403 * filesys.c (scm_directory_stream_p): Renamed from scm_directory_p.
404 At the Scheme level, "directory?" -> "directory-stream?".
405 (scm_dir_print): Use the phrase "directory stream" in printed form.
406 * filesys.h (scm_directory_stream_p): Prototype renamed
409 * Makefile.am (CLEANFILES): Remove versiondat.h; that should only
410 be removed by `make distclean', since it's generated by configure.
411 * Makefile.in: Regenerated.
412 (Thanks to Robert Bihlmeyer.)
414 * strop.c (scm_substring_move_x): Signal an error if start1
415 doesn't come before end1. (Thanks to Karoly Lorentey).
417 * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
418 calling SCM_NIMP. (Thanks to Karoly Lorentey).
420 * version.c (scm_libguile_config_stamp): Deleted. See
421 corresponding change to ../ice-9/boot-9.scm.
422 * versiondat.h.in: Remove definition for GUILE_STAMP.
423 * version.h: Delete prototype.
424 * Makefile.in: Regenerated.
426 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
428 * filesys.c (scm_directory_p): new procedure "directory?" Returns
429 a boolean indicating whether its argument is a directory
430 port as returned by opendir (thanks to Dirk Herrmann for the
433 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
435 * backtrace.c (display_frame_expr): Don't print a newline.
436 (display_frame): Print the newline here instead.
437 (display_backtrace_body): Don't print "Backtrace:".
438 (scm_backtrace): Print "Backtrace:" here instead.
440 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
442 * procs.c (scm_setter): Signal WTA if handed an entity or operator
445 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
446 primitives. (Thanks to Greg Badros);
447 (scm_hook_to_list): New primitive; Hooks are now smobs.
449 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
451 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
452 of #f for the 10th vector element to avoid an exception
453 seen by Bernard Urban.
454 (scm_mktime): unneeded ASSERT removed.
456 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
458 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
461 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
463 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
465 * numbers.c: Converted comparison operations to dispatch on
466 generic if args don't match.
468 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
470 1999-09-06 James Blandy <jimb@mule.m17n.org>
472 * guile-snarf.c: Deleted. Snarfing should respect CPP
473 conditionals, so it needs to actually run CPP. Bleah.
475 1999-09-05 James Blandy <jimb@mule.m17n.org>
477 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
478 * guile-snarf.in: Be sure to exit with an error if CPP does.
479 * Makefile.am (.c.x): Delete the .x file and exit with an error
480 status if guile-snarf exits with an error status.
481 * Makefile.in: Regenerated.
483 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
484 scm_makekey, which doesn't exist any more. Guess nobody's using
487 * guile-snarf.c: New implementation of guile-snarf, meant to be
488 more robust than the shell script. I think it's complete, but I
489 haven't tested it at all, and I haven't changed the build process
490 to actually use it. We should compare its output against that of
491 the existing shell script, for all source files.
493 * guile-snarf.c (parse_args): Abort if we haven't handled some
496 1999-09-03 James Blandy <jimb@mule.m17n.org>
498 * load.c (scm_search_path): If the filename has any extension at
499 all, ignore the entire list of extensions. Also, don't check whether
500 the file is accessible. If the file exists, accessible or not, we
501 should return it. Inaccessible files should cause an error later.
502 (Thanks to Keisuke Nishida for the suggestions.)
504 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
506 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
507 atexit not available. (sunos4.1.4 needs it.)
509 1999-09-01 James Blandy <jimb@mule.m17n.org>
511 I take it all back --- bcopy does handle overlapping source and
512 destination areas correctly. At least on every system I could
513 find. But it is better to use AC_REPLACE_FUNCS than to introduce
514 new CPP conditionals.
515 * memmove.c: New file, implementing memmove in terms of bcopy.
516 * scmconfig.h.in: Regenerated.
518 Allocators should use the `void *' type for generic pointers.
519 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
520 argument and return types.
521 * gc.h: Corresponding changes to prototypes.
524 1999-08-31 James Blandy <jimb@mule.m17n.org>
526 * numbers.c (scm_init_numbers): Claim to support the `complex'
527 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
529 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
530 find (ice-9 boot-9) when Guile was compiled in a separate
531 directory from the source. (Thanks to Rodney Brown.)
532 * Makefile.in: Regenerated.
534 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
535 table lengths by the size of a single element when growing the
536 table. (Thanks to Bill Schottstaedt.)
538 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
540 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
541 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
542 since that cuts down the time for type dispatch by 50%.
544 1999-08-30 James Blandy <jimb@mule.m17n.org>
546 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
547 not a correct substitute for memmove, because it doesn't handle
548 overlapping source and destination areas on many platforms.
549 Overlaps are the primary reason to use memmove in the first place.
550 * ports.c (scm_ungetc): Same.
551 * strop.c (scm_substring_move_x): Same.
553 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
555 * gc.c (scm_init_storage): Skip registration of cleanup on systems
556 which lack atexit. (Is it important that cleanup is made
557 properly? Maybe we should replace all `exit' with `scm_exit' and
560 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
561 scm_struct_free_standard, scm_struct_free_entity): Declared to
562 return scm_sizet instead of size_t.
564 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
565 there on sunos4.1.4.)
567 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
569 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
570 Account for the case when second argument is unbound.
572 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
573 (Thanks to Karoly Lorentey.)
575 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
576 isn't present. (Thanks to Suzuki Toshiya.)
578 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
581 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
584 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
585 Bernard Urban and Ian Grant.)
587 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
588 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
589 change in the representation of entities and operators.)
591 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
593 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
594 don't allocate zero bytes (thanks to Bill Schottstaedt).
596 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
598 * procs.c (scm_setter): Converted to use generic dispatch.
600 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
603 * load.c (scm_search_path): Don't try extensions which already are
604 present at the end of the filename.
605 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
607 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
609 Cleanup and simplification of generic method dispatch.
610 Also, the quadruple representation of entity and operator
611 procedures has been replaced with single.
613 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
615 * print.c (scm_isymnames): Removed #@hash-dispatch.
617 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
618 from eval.c; Support 0 arity methods.
619 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
620 (scm_apply_generic_env): Removed.
621 Replaced slots proc0-3 with procedure.
623 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
624 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
625 SCM_OPERATOR_PROCEDURE.
626 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
627 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
629 * struct.c, struct.h: Replace 4 procedure slots with one.
630 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
632 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
635 * eval.c (scm_sym_args): Removed.
636 (SCM_CEVAL): Simplified entity application.
637 Moved dispatch code to objects.c.
639 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
641 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
643 * sort.c (closureless): Use scm_eval_body.
645 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
646 with a symbol as last form was first called normally and then via
647 `map' or some other mechanism using primitive apply, an ILOC was
650 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
652 This change extends the representation of primitive procedures
653 with more data fields, e.g. a place for documentation and true
654 procedure properties.
656 * procs.c, procs.h (scm_subr_entry): New type: Stores data
657 associated with subrs.
658 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
659 SCM_SUBR_DOC): New macros.
660 (scm_subr_table): New variable.
661 (scm_mark_subr_table): New function.
663 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
665 * gc.c (scm_gc_mark): Don't mark subr names here.
666 (scm_igc): Call scm_mark_subr_table.
669 This change implements a scheme for letting a generic work as a
670 shadow for a primitive procedure. If the primitive procedure
671 can't dispatch on its arguments, control is left over to the
672 generic. Normal wrong type arg errors will be generated until the
673 user has hung the first method on the primitive.
675 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
677 * procs.c, procs.h (scm_subr_p): New function (used internally).
679 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
681 * objects.c, objects.h (scm_primitive_generic): New class.
683 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
685 * print.c (scm_iprin1): Print primitive-generics.
687 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
688 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
690 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
691 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
692 primitives). NOTE: This means that it is now *required* to use
693 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
694 obscured representation that will be removed in the future anyway,
695 so backward compatibility is no problem here).
697 * numbers.c: Converted most numeric primitives (all but bit
698 comparison operations and bit operations) to dispatch on generic
702 Better support for applying generic functions.
704 * eval.c, eval.h (scm_eval_body): New function.
706 * objects.c (scm_call_generic_0, scm_call_generic_1,
707 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
711 Optimization of the generic function dispatch mechanism.
713 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
714 called scm_memoize_method instead of doing a second lookup.
716 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
721 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
722 scm_sysintern so that the binding connected with the subr name
723 isn't cleared when we give set = 0.
726 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
728 More transparent handling of ports with print states.
730 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
731 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
732 instead of a pair of a port and a print state. We'll need to cons
733 once extra in scm_printer_apply but the type system will be
734 cleaner, it will mix better with GOOPS, and, it will be even more
735 transparent to the user.
737 * print.c (scm_get_print_state): New procedure: Given an output
738 port, return the print state associated to it in the current print
739 chain, if one exists;
740 (scm_port_with_print_state): New procedure: Associate a
741 print-state with a port.
742 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
743 (scm_printer_apply): Wrap port and pstate as a smob;
744 (print_state_printer): Removed.
746 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
748 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
751 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
752 testing (otherwise the port-print-state trick won't be transparent
753 to the user; one example where this caused problems was in the
754 (ice-9 format) module).
756 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
758 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
759 SCM_UNSPECIFIED instead of the set value.
761 1999-08-20 James Blandy <jimb@mule.m17n.org>
763 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
765 * ports.h (enum scm_port_rw_active): New enum, containing
766 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
767 zero). The debugger knows about enums, but doesn't know about
769 (typedef scm_port): Declare rw_active member to be an enum
771 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
773 * ports.c (scm_add_to_port_table): Same.
774 * strports.c (st_flush, st_end_input): Same.
776 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
777 scm_must_realloc, and scm_done_malloc as appropriate.
779 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
781 * sort.c (quicksort): Added condition to protect the algorithm
782 from crashing the interpreter if the less predicate is buggy.
784 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
786 * fports.c (fport_write): fix line-buffering mode again.
787 (scm_open_file): recognise 'l' for line-buffering.
788 (scm_setvbuf): recognise _IOLBF for line-buffering.
790 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
792 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
795 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
798 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
800 * fports.c (fport_write): use memcpy instead of strncpy, in case
801 the data contains NUL.
803 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
805 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
807 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
808 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
809 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
810 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
811 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
812 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
813 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
814 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
815 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
816 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
817 scm_sym_ as prefix for symbols.
819 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
821 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
822 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
823 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
824 scm_sym_atcall_cc): Made global.
826 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
828 * eval.c (scm_sym_args): Made global.
830 * objects.c (scm_set_object_procedure_x): Disallow setting of
831 procedures for pure generic functions.
833 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
835 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
836 Scheme name from lseek to seek, but lseek was added recently so
837 it shouldn't be a big problem.
838 * ports.c, gdbint.c, ioext.c: changed callers.
840 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
842 * fports.c (fport_input_waiting): if select is used, return 1
843 instead of whatever FD_ISSET expands to. maybe it will be useful
844 to interpret the value from the input_waiting ptob procedure as a
845 lower bound on the number of bytes available.
847 * Mikael asked for a few names to be changed...
849 * ports.c (scm_make_port_type): take the write procedure as the
850 second argument instead of the flush procedure.
851 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
852 fflush -> flush, read_flush -> end_input, fclose -> close,
853 fill_buffer -> fill_input, ftruncate -> truncate,
854 input_waiting_p -> input_waiting.
856 * ports.c (end_input_void_port): was read_flush_void_port.
857 (scm_set_port_end_input): was scm_set_port_flush_input.
858 (scm_set_port_flush): was scm_set_port_write.
859 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
860 (scm_end_input): was scm_read_flush.
861 (scm_fill_input): was scm_fill_buffer.
862 (scm_flush): was scm_fflush.
863 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
864 (fport_end_input): was local_read_flush.
865 (fport_flush): was local_fflush.
866 (fport_close): was local_fclose.
867 (fport_truncate): was local_ftruncate.
868 (fport_seek): was local_seek.
869 (fport_free): was local_free.
870 (fport_fill_input): was fport_fill_buffer.
871 * strports.c (st_end_input): was st_read_flush.
872 (st_truncate): was st_ftruncate.
873 * vports.c: (sf_flush): was sfflush.
874 (sf_close): was sfclose.
875 (sf_fill_input): was sf_fill_buffer.
877 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
880 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
882 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
883 forms now contain the expressions to be dispatched upon instead of
884 depending on a surrounding lambda or let; Generic function
885 dispatch has been optimized; `apply' on a generic function now
886 works a little bit strangely. It uses a trick so that the type
887 dispatch code in SCM_CEVAL can be reused.
889 * objects.h, objects.c (scm_apply_generic_env): Added (used by
891 (scm_operator_p): Added.
892 (scm_sym_atdispatch): Added.
893 (scm_set_object_procedure_x): Modified to handle the new style
895 (scm_object_procedures): New debugging procedure.
897 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
899 * eval.c, eval.h (scm_sym_args): Added.
901 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
903 * feature.c, feature.h (scm_c_run_hook): Added.
905 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
906 cdrxnoap and loopnoap instead of begin and loop.
908 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
910 * ports.c (scm_putc, scm_puts),
911 * unif.c (scm_uniform_array_write): use scm_lfwrite.
912 * ports.c (scm_putc): change type of first argument from int to char.
914 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
916 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
917 SCM_IM_HASH_DISPATCH.
919 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
920 (scm_si_redfined, scm_si_hashsets): Moved.
922 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
923 flag which combines type and status info so that the class
924 redefinition protocol has zero cost during normal execution.
926 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
928 * ports.h (scm_ptob_descriptor): include a write procedure again.
929 it's more efficient for unbuffered fports (e.g., sockets.)
931 * ports.c (scm_puts): use ptob->write.
932 * vports.c (scm_make_sfptob): set write proc in ptob.
933 * strports.c (scm_make_stptob): set write proc in ptob.
934 * ports.c (write_void_port): new procedure.
935 * vports.c (sf_write): new procedure.
936 * ports.c (scm_lfwrite): use ptob->write.
937 * strports.c (st_write): new procedure.
938 * fports.c (fport_write): new procedure.
939 (scm_make_fptob): set write in ptob to fport_write.
940 * ports.h: prototype for scm_set_port_write.
941 * ports.c (scm_make_port_type): initialise ptob write procedure.
942 (scm_set_port_write): new proc.
944 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
946 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
947 until we've verified that it is actually a port. (Thanks to
950 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
952 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
953 code, particularly an unnecessary test (len != size, where len ==
954 size). (Was this leftovers from debugging code, or have I missed
957 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
958 size. (Thanks to James Dean Palmer.)
960 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
961 (Thanks to Lorentey Karoly.)
963 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
965 * eval.c (scm_m_expand_body): Use scm_cons_source.
967 * struct.c (scm_print_struct): Use vtable name.
969 * print.c (scm_init_print): Set name of print state type.
971 * stacks.c (scm_init_stacks): Set name of stack type.
973 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
975 * eval.c (SCM_CEVAL): Removed old implementation of internal
978 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
980 * debug.c, debug.h (scm_reverse_lookup): Added.
981 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
982 internal procedure definitions; Don't use scm_i_inner_name.
984 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
987 * eval.h: Added prototypes for multi language support functions.
989 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
990 improper lists in the low-level representation, since that will
991 cause a begin to be prepended at macro expansion.
993 * eval.c (scm_cons_source): Version of cons which copies source
994 properties from an existing cell.
995 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
997 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
998 procedure source before calling scm_unmemocopy instead of faking
1001 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1003 Ported `internal defines' fix from SCM. Original ChangeLog entry:
1005 1998-07-09 Radey Shouman <radey@colorage.com>
1007 * eval.c (ceval_1): Modifications to allow rewriting of interal
1008 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
1009 body of which it is the CAR is macro expanded by m_expand_body,
1010 which rewrites internal DEFINE.
1012 (m_expand_body): Added.
1014 (m_macroexp1): Added argument to control error checking:
1015 m_expand_body may speculatively expand forms in the wrong
1016 environments. Made argument number checks conditional on
1019 (m_body): Added, error checks bodies and inserts the ISYM tokens.
1021 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
1024 (m_cond): (m_case): (m_quote): Modified to avoid destructively
1025 changing their argument forms. Since m_expand_body
1026 speculatively macro expands forms the process must be
1029 (m_ident_eqp): Fixed to use proper environment.
1031 (renamed_ident): Added DEFER_INTS_EGC.
1033 Added prototypes for static functions.
1039 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
1040 is false, do not produce an error for unbound variables, return a
1041 pointer to cell_undef instead.
1043 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
1047 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
1048 destructively changing their argument forms. Since m_expand_body
1049 speculatively macro expands forms the process must be reversible.
1051 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
1052 SCM_IM_LET introduced by named lets.
1054 (scm_m_letstar): Use scm_m_body instead of bodycheck.
1056 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
1057 scm_letrec. scm_letrec1 does not check for a null binding and
1058 takes an additional argument to specify the ISYM of the body. Use
1059 scm_m_body instead of bodycheck.
1061 (scm_m_let): Use scm_m_body instead of bodycheck.
1063 (scm_m_expand_body, scm_macroexp): New.
1065 (unmemocopy): Account for ISYMs introduced by scm_m_body.
1067 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
1068 check=1. Throw error for internal defined that have not been
1069 rewritten by scm_m_expand_body.
1071 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
1072 Removed prototype for SCM_APPLY.
1074 * tags.h: Added extern declaration of scm_isymnames.
1076 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>

1080 * lang.c: New file: Beginning of multi-language support.

1084 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
1085 (scm_dynamic_wind): Added argument checking for the after guard so
1086 that we don't add garbage on the dynwind chain.
1087 (scm_swap_bindings): Added.
1089 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
1090 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
1091 (scm_isymnames): New isyms for multi-language support.

1094 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
1095 forms for multi-language support.
1097 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1099 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
1101 Renamed functions in the random function library interface

1111 scm_set_ptob_XXX --> scm_set_port_XXX.
1113 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1115 * ports.c, ports.h (scm_make_port_type): New interface for
1116 creation of port types (replaces scm_newptob). Just as for the
1117 smobs, we need to separate the internal representation of smob
1118 types from the interface, so that we easily can add new fields and
1119 rearrange things without caring about backward compatibility.
1120 This change was forced by the need in GOOPS to create classes
1121 representing port types.
1122 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
1123 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,

1125 scm_set_ptob_input_waiting_p): New setters.
1126 (scm_newptob): Rewritten to use scm_make_port_type. For backward
1128 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.

1136 * fports.c (prinfport): Moved code from ports.c.
1137 (local_free): Added.
1138 (scm_fptob): Removed. Instead use new interface.
1139 (scm_make_fptob): Added. (Need to create basic ports in a
1140 specific order in ports.c.)
1142 * strports.c (scm_stptob, prinstpt, noop0): Removed
1143 (scm_make_stptob): Added.
1145 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.

1157 Removed #include "genio.h"
1159 * objects.c (scm_make_port_classes): New function ptr.
1161 1999-07-24 Gary Houston <ghouston@easynet.co.uk>

1165 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
1166 allow the 1st argument to be a fdes or filename as well as a
1167 port (as in the filesys.c version).
1169 * filesys.c (scm_truncate_file): removed.
1171 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1173 * readline.c, readline.h: Removed.
1175 * objects.c, objects.h (scm_port_class): Added.

1185 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1187 * init.c: Make sure that scm_post_boot_init_modules is called only
1188 once. (Important when using a dumped image.; Thanks to Bernard
1191 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
1193 * guardians.c (scm_guardian_zombify): Separate scanning for
1194 zombies from marking the pairs of the free list.
1196 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
1197 use the macros. (Thanks to Michael Livshin.)
1199 * eval.c (scm_m_lambda): Let bodycheck check the body of the
1200 lambda. Let your sins be purified by the blood of the lambda.
1201 (Thanks to Eric Hanchrow.)
1203 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
1204 (Thanks to Valdis Kletnieks.)

1208 * filesys.c: #include <io.h>, if we have it.
1209 * scmconfig.h.in: Regenerated.
1211 * stime.c (ftime): Delete declaration for this function --- let
1212 the system supply it.
1214 Cleanups from John Bley.
1216 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
1218 * gsubr.c: Don't include "gsubr.h" twice.
1220 Cleanups for compilation on Irix 6, from David Kaelbling.
1222 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
1223 regex_t pointer. This is what the callers have, mostly.
1224 (scm_regexp_exec): Don't forget to pass the `rx' argument to
1225 scm_regexp_error_msg.
1227 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
1228 int. That way, if we get a warning on this line, it's more likely
1229 that we're really missing bits we care about.
1231 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
1234 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
1235 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
1236 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
1237 cast at all is more appropriate in every case. At the moment, we
1238 assume everywhere that SCM is an integral type anyway.
1240 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
1242 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment

1248 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
1249 fports.c (fport_fill_buffer): implement the interface change.
1251 * ports.c (scm_fill_buffer): interface change: no longer increments
1252 read_pos past the character that's returned. it seems clearer to
1253 leave it to the caller to decide what to do (thanks Jim).
1255 * vports.c (sf_fill_buffer): put the read char into the buffer
1256 as well as returning it.
1258 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

1276 it's greater and reset read_buf_size.
1277 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
1278 to be maintained for output ports too (it holds the written
1279 part of the string, while write_buf may have unwritten buffer
1281 (st_truncate): rewritten.
1282 (top of file): added a few notes.
1284 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
1286 Patch from Greg Badros:
1287 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
1288 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
1289 (function pointer) argument to scm_make_gsubr and scm_make_subr
1290 calls. This avoids warnings in C++ programs using guile-snarf.
1292 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
1294 * strports.c (st_grow_port): set pt->read_pos. set
1295 pt->read_buf_size one less than pt->write_buf_size if there's
1296 an unwritten char at the end of the string. similarly for
1298 (st_resize_port): renamed from st_grow_port.
1299 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
1300 seek from read_end instead of write_end for SEEK_END.
1301 (st_ftruncate): calculate current length using readbuf, not write
1303 (scm_strport_to_string): use read_buf_size for length.
1304 (stfill_buffer): don't re-initialise the readbuf.

1320 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
1321 and "bigneg" smob types.
1323 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
1324 SCM_RETURN_NEWSMOB macro. Added protos for new functions in

1328 use SCM_NEWSMOB or SCM_RETURN_NEWSMOB in constructors instead of
1329 SCM_NEWCELL and setting the CAR/CDR by hand.

1413 trinary conditional in order for the flag computation to be
1416 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1418 * struct.c, struct.h:
1420 In order to support different kinds of deallocation, a destructor
1421 slot has been added to struct vtables. This allows for structs
1422 containing pointers to other memory blocks.

1496 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1497 around the condition of an `if', `while', etc., even if the

1499 surrounded by parens. It's more readable.
1501 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1502 proper lists, and of the appropriate lengths.
1503 (check_map_args): New function. (Thanks to Greg Harvey for the
1506 1999-06-19 Michael Livshin <mike@olan.com>
1508 * guardians.c (guardian_t): `next' - new field to be used for

1537 Fix from Ken Raeburn <raeburn@raeburn.org>:
1538 * weaks.c (scm_make_weak_vector): Add another extra slot before

1543 (scm_weak_size, scm_n_weak): Deleted.
1544 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
1545 vectors without allocating new storage during GC, using
1546 scm_weak_vectors as the head of the chain.
1547 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1548 instead of stepping through an array.

1561 * fports.c (local_seek): Signal an error if the seek fails.
1562 * ports.c (scm_lseek): Don't check return value of port's seek

1577 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1579 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1580 it shows up as terrible performance, as we GC constantly.

1592 * ports.h (SCM_BUFLINE): New flag for ports.
1593 * init.c (scm_init_standard_ports): Request line-buffering on
1594 the standard output port.
1595 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1597 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,

1600 Gary Houston's open-buffer port patches:
1602 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1604 * ports.c: (scm_lseek): clear buffers even if just reading current
1607 * fports.c (local_fclose): call local_fflush unconditionally.
1608 (various): don't use the scm_must... memory procs.
1610 1999-04-25 Gary Houston <ghouston@easynet.co.uk>
1612 * ports.h (scm_port): make read_pos a pointer to const.
1613 strports.c: take care of rw_active and rw_randow.
1614 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
1615 strports.c (scm_mkstrport): check that pos is reasonable.
1616 ioext.c (scm_ftell, scm_fseek): use lseek.
1617 (SCM_CLEAR_BUFFERS): macro deleted.
1618 ioext.c (redirect_port: use ptob fflush, read_flush.
1619 ports.h (scm_ptobfuns): add ftruncate.
1620 ports.c (scm_newptob): set ftruncate.
1622 ports.c (scm_ftruncate): new procedure.
1623 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
1624 strports.c (st_seek, st_grow_port): new procs.
1625 fports.h (scm_port): change size types from int to off_t.
1626 ports.c (scm_init_ports): initialise the seek symbols here
1627 instead of in ioext.c.
1628 strports.c (scm_call_with_output_string): start with an empty
1629 string, so seek and ftruncate can be used.
1631 gdbint.c: adjust string port usage.
1633 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1635 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1636 equivalent to fflush for the read buffer.
1637 * ports.c (scm_newptob): set read_flush.
1638 ports.c (void_port_ptob): set read_flush.
1639 fports.c (local_read_flush): new proc. add to ptob.
1640 strport.c (st_read_flush): likewise.
1641 vport.c (sf_read_flush): likewise.
1642 fports.h (struct scm_fport): remove random member. there's nothing

1644 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1645 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1646 ptob proc if the read buffer is filled.
1648 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1650 * ports.h (scm_port): add a rw_random member and replace
1651 reading and writing members with rw_active member.
1652 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1654 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1656 * ports.h (struct scm_port_table): add writing and reading members
1657 to replace write_needs_seek: it isn't good enough for non-fports.
1658 ports.c, ioext.c, fports.c: corresponding changes.
1659 (struct scm_port_table): give it a typedef and rename to scm_port.
1660 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1661 corresponding changes.

1671 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1672 signals (it was only being done for handlers installed from Scheme).
1673 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1674 waiting for input caused an EINTR error from read.
1676 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1678 * ports.h (struct scm_port_table): make all the char members
1679 unsigned, so they convert to int without becoming negative if large.
1681 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1683 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1684 with threads enabled. rename this procedure to
1685 fport_wait_for_input and take a port instead of a fdes.
1686 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1688 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1689 get readline support working again: use fdopen to get FILE objects.
1691 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1693 * gc.c (scm_init_storage): install an atexit proc to flush the
1695 (cleanup): the new proc. it sets a global variable which can be
1696 checked by the ptob flush procs to avoid trying to throw
1697 exceptions during exit. not very pleasant but it seems more reliable.
1698 * fports.c (local_fflush): check terminating variable and if set
1699 don't throw exception.
1700 * CHECKME: that the atexit proc is installed if unexec used.
1702 * throw.c (scm_handle_by_message): don't flush all ports here.
1703 it still causes bus errors.
1705 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1706 and move to ioext.c.
1708 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1710 * ports.c (scm_char_ready_p): check the port buffer and call the
1711 ptob entry if needed.
1713 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1714 ptob initialisers. use it in char-ready
1716 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1718 * vports.c (sfflush): modified to write a char (since softports
1719 currently use shortbuf.)
1721 * fports.c (scm_standard_stream_to_port): moved to init.c and
1724 * init.c (scm_init_standard_ports): make stdout and stderr
1725 unbuffered if connected to a terminal. with stdio they
1726 were line-buffered by default.
1728 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1731 * ports.h (scm_ptobfuns): change fflush return to void.
1732 change flush proc definitions.
1734 * strports.c (scm_call_with_output_string): get size from
1735 buffer instead of port stream.
1736 (st_flush): new proc.
1738 * ports.h (struct scm_port_table): added write_end member,
1739 as an optimisation. set it where write_buf_size is set.
1741 * ports.h (struct scm_port_table): change stream from void *
1742 back to SCM. SCM presumably must be large enough to hold a
1743 pointer (and probably vice versa but who knows.)
1744 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1746 (scm_puts): rewritten
1747 * fports.c (local_ffwrite, local_fputs): removed.

1760 * fports.c: set it to local_seek, new procedure.
1763 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1764 use ptob for seek. take ptob instead of fport arg.
1766 * ports.h (struct scm_port_table): new member write_needs_seek,
1767 replaces reading member in fport struct.
1769 * vports.c (sfgetc): store the getted char into the buffer.
1770 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1771 the Scheme interface is still a procedure that gets a char.
1772 (scm_make_soft_port): set up the port buffer (shortbuf).
1774 * fports.c (local_fgetc, local_fgets): deleted.
1775 * strports.c (stgetc): likewise.

1782 (stfill_buffer): new proc.
1784 * ports.h: fport buffer moved into port table: to be
1785 used for all port types.

2091 * modules.c: #include "procprop.h"
2092 (scm_system_module_env_p): Assume root environment is no lookup
2095 * debug.c, eval.c, evalext.c, gdbint.c stacks.c:
2096 #include "modules.h".
2098 * modules.c, modules.h, eval.c, eval.h (scm_env_top_level,
2099 scm_top_level_env, scm_system_module_env_p): Moved to modules.c.
2101 * eval.c, eval.h (scm_top_level_lookup_closure): Removed.

2105 * error.c (scm_wta): Pass SCM_LIST1 (arg) instead of SCM_EOL to
2106 scm_misc_error when pos is a string. This allows for dispatching
2107 arbitrary error messages with one argument via SCM_ASSERT:
2108 SCM_ASSERT (<cond>, obj, "Undigestable object: %S", <subr>);
2110 1999-03-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

2116 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2118 Most of this batch of changes is about how to deal with extended
2119 types when an object system is loaded into Guile. A nice object
2120 system is capable of representing Guile's types as class objects.
2122 For example, we want a regular expression to be of class <regex>.
2123 But regular expressions are smobs which aren't under direct
2124 control of the object system, so there has to be some mechanism
2125 which informs the object system that a new class should be created
2126 which can represent the smob type. I call this a "wrapper class".
2128 * objects.c: #include "smob.h";
2129 (scm_class_keyword): Removed. (Class is automatically created by
2131 (scm_smob_class): Array of smob classes indexed by smobnum.
2132 (scm_make_extended_class): "Plugin" function pointer for creation
2133 of wrapper classes for smob and struct types.
2134 (scm_class_of): Handle compiled closures. (Currently regarded as
2136 Use scm_smob_class to handle smob types;
2137 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
2138 through scm_smob_class;
2141 * smob.c (scm_newsmob): Also create a wrapper class if
2142 scm_smob_class has been initialized.
2144 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
2145 type code and smobnum.
2147 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
2148 (scm_struct_table): Weak key table with auxilliary information for
2149 struct types. Currently used for names and wrapper classes.
2150 (scm_struct_ihashq): Hash function for structs.
2151 (scm_struct_create_handle): Get/create entry in scm_struct_table.
2152 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
2153 for accessing names of vtables. The record implementation in
2154 boot-9.scm currently uses the setter to record the name of record
2155 types. When the object system is initialized, it can use this
2156 information to create wrapper classes with suitable names.
2157 (scm_init_struct): Allocate scm_struct_table.
2158 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
2159 (struct tags are a finite resource and we might want to restrict
2160 the use of tags to vtables only. E.g., Goops only uses tags for
2162 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
2164 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
2167 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
2168 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
2169 Used for access of struct table entries.
2171 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
2172 (scm_hash_fold): New procedure. Used to process all entries in a
2173 hash table (in no particular order).
2175 Argh! For the umpteenth time I got compilation errors because of
2176 the "intuitive" name `kw'. This has to have an end:
2178 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
2179 "kw" --> "keywords" everywhere.
2180 (I doubt that this will cause big compatibility problems since the
2181 application interface is unaffected.)
2183 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
2185 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2187 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
2188 column inums to native form.
2190 Improvement of backtraces: Introduces a new stack narrowing
2191 specifier, #t, for the inner cut. (See further in the comments in
2192 stacks.c:narrow_stack ().)
2194 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
2195 (Used to flag certain system procedures which shouldn't turn up in
2198 * eval.c (scm_sym_system_module): New symbol. (Used to flag
2199 modules which aren't "user" modules and the code of which

2215 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
2217 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
2218 procedure throughout.
2220 * print.c (scm_iprin1): Removed extraneous space when printing
2221 procedure-with-setters.
2223 Entity and operator setter slots were introduced as a complement
2224 to the <procedure-with-setter> type in order to support entities
2225 and operators with setters in a reasonable and efficient way.
2226 * procs.c (scm_procedure, scm_setter): Handle entity and operator

2242 directly through the instance.
2244 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
2246 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
2247 scm_struct_i_flags instead of scm_vtable_index_layout!
2249 * list.c (scm_list_star): New procedure.
2251 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

2332 SYMB now point to const.
2334 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2336 * print.c (scm_iprin1): Use scm_procedure_name instead of
2337 scm_procedure_property for compiled closures.
2339 * tags.h (scm_tc7_pws): New procedure type. Four representations
2340 for procedure-with-setters were considered before selecting this
2343 1. A closure where the CODE and ENV slots are used to represent
2344 the getter and a new SETTER slot is used for the setter. The
2345 original getter is stored as a `getter' procedure property. For
2346 closure getters, the CODE and ENV slots contains a copy of the
2347 getter's CODE and ENV slots. For subr getters, the CODE contains
2350 2. A compiled closure with a call to the getter in the cclo
2351 procedure. The getter and setter are stored in slots 1 and 2.
2353 3. An entity (i.e. a struct with an associated procedure) with a
2354 call to the getter in the entity procedure and the setter stored
2355 in slot 0. The original getter is stored in slot 1.
2357 4. A new primitive procedure type supported in the evaluator. The
2358 getter and setter are stored in a GETTER and SETTER slot. A call
2359 to this procedure type results in a retrieval of the getter and a
2360 jump back to the correct eval dispatcher.
2362 Representation 4 was selected because of efficiency and
2365 Rep 1 has the advantage that there is zero penalty for closure
2366 getters, but primitive getters will get considerable overhead
2367 because the procedure-with-getter will be a closure which calls
2370 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
2371 <procedure-with-setter>, but together with rep 2 it suffers from a
2372 three level dispatch for non-GOOPS getters:
2374 cclo/struct --> dispatch proc --> getter
2376 This is because the dispatch procedure must take an extra initial
2377 argument (cclo for rep 2, struct for rep 3).
2379 Rep 4 has the single disadvantage that it uses up one tc7 type
2380 code, but the plan for uniform vectors will very likely free tc7
2381 codes, so this is probably no big problem. Also note that the
2382 GETTER and SETTER slots can live directly on the heap, using the
2383 new four-word cells.
2385 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

2587 definitions of the rudimentary classes described by objects.h.
2589 * objects.c, objects.h (scm_entity_p): New procedure. Together
2590 with the predicates scm_procedure_p and scm_struct_p, this
2591 predicate makes it possible to differ between structs, entities
2594 * modules.c, modules.h (scm_resolve_module): New function.
2596 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2598 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2599 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2602 * objects.c (scm_entity_p): New procedure.
2604 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
2605 for asubrs, rpsubrs, lsubrs and lsubr_2s.
2607 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2609 * procprop.h (scm_i_procedure_arity): Added declaration.
2611 * procprop.c (scm_i_procedure_arity): Made global; New code to
2612 handle operators and entities.
2613 (scm_procedure_property): No need to call scm_procedure_p since
2614 scm_i_procedure_arity now does all necessary type checking.
2615 Added #include "objects.h".
2617 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2618 s_add_hook_x --> s_remove_hook_x.
2619 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
2620 Added #include "procprop.h"
2622 * feature.c, feature.h (scm_reset_hook_x): New procedure.
2623 (scm_make_hook): Optional argument defines number of arguments to
2625 (scm_make_named_hook): Take number of args as second arg.
2626 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2627 boot-9.scm for a while); First arg is the hook. The rest are
2628 arguments passed on to the hook procedures.
2630 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2632 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2633 scm_logbit_p): Do the computation in ulongs. This is not as nice
2634 as doing it in bignums, but at least it's good enough for
2635 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2637 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2638 subexpressions. (Thanks to Charbel Jacquin.)
2640 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2642 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2643 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2644 (scm_make_named_hook): New function.
2646 * feature.c: Added #include "eval.h".
2648 * modules.c (scm_make_module): Beautify the module.
2650 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2652 * modules.c, modules.h: New files: C interface to modules. (This
2653 is necessary in order to interface the object system to Guile
2654 properly. The guts of these modules will be replaced by the new
2655 module system in the future.)
2657 * init.c: Added #include "modules.h"
2658 (scm_boot_guile_1): Call scm_init_modules.
2659 (invoke_main_func): Call scm_post_boot_init_modules.
2661 * Makefile.am: Added modules.c, modules.x, modules.h.
2663 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2665 * procs.c: #include "objects.h"
2666 (scm_procedure_p): Return #t also on structs which are operators.
2668 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2669 <operator-metaclass> and <entity-class> to <standard-class>,
2670 <operator-class> and <entity> in order to conform with STKlos
2673 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2674 which isn't an operator.
2675 (SCM_APPLY): Ditto, but jump to badproc.
2677 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2679 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2680 Previously, structs implanted in code were interpreted as forms
2681 the operator of which was a gloc. We solve this by checking for
2682 the zero in the emulated vcell in the struct vtable. Since
2683 implanted structs always will look like forms with a gloc
2684 operator, execution will only be slowed down by maximally one
2685 extra test-and-branch per application.
2687 * evalext.c (scm_definedp): Removed check for isyms; Added a
2688 second optional argument: It is now possible to supply an
2689 evaluation environment in which to look for the symbol.
2691 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2693 * readline.c (scm_init_readline): Set
2694 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2696 * coop.c (coop_condition_variable_wait): Removed
2697 (coop_condition_variable_wait_mutex): Folded logic of
2698 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2699 prevent condvar signal lossage. Previously, another thread could
2700 start to run after unlocking the mutex but before putting the
2701 current thread on the wait queue. If that thread then would
2702 signal the first, the signal would be lost. (Thanks to Christian
2705 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2707 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2710 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2712 * objects.c (scm_i_make_class_object): Renamed from
2713 make_class_object; exported; error checking moved to
2714 scm_make_class_object and scm_make_subclass_object.
2715 (scm_make_class_object, scm_make_subclass_object): Use
2716 scm_i_make_class_object.
2717 (scm_make_subclass_object): Let the subclass have same metaclass
2720 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2722 * debug.c (scm_debug_options): Bugfix: Set the value of
2723 scm_stack_checking_enabled_p after setting debug options;
2724 #include "stackchk.h". (Thanks to Richard Polton.)
2726 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2728 * unif.c (scm_array_contents): removed unnecessary test for 0
2731 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2733 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2734 Replaced by macro `collect' in boot-9.scm.
2736 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2738 * eval.c (scm_copy_tree): Copy source properties if existent.
2740 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2741 don't, we may end up passing memoized source to a transformer.)
2743 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2745 * stack.c (get_applybody): Help function which lookups the first
2746 body form of the apply closure.
2747 (read_frames): Prevent the source of the first form of the apply
2748 closure from being recorded. This would only be confusing.
2750 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2751 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2753 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2755 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2757 (read_frames): Use SCM_MACROEXPP.
2759 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2761 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2762 don't contain interesting information since all arguments are
2763 present in the frame which applies the compiled closure anyway.);
2764 Skip the transformer application frames.
2766 * print.c (scm_iprin1): Print gsubrs as primitives.
2768 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2770 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2772 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2773 that we can identify these in a backtrace. (This change doesn't
2774 introduce any significant speed penalty.)
2776 * eval.c: Added note about `serial-map' using scm_map.
2778 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2779 readline options. They should reside in their own options array.
2781 * readline.c, readline.h (scm_readline_options,
2782 scm_readline_opts): Moved readline options here.
2784 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2786 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2787 SCM_ROCHARS instead of SCM_CHARS.
2789 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2790 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2792 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2794 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2795 This is quite important since the latter clears the
2796 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2797 every single character read...
2799 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2801 * print.c (scm_iprin1): Removed suspect looking (and indeed
2802 malevolent) semicolon after test for user supplied closure print
2803 procedure. (Thanks to Telford Tendys.)
2805 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2806 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2807 starting to search the list. Removed call to sloppy_mem_check.
2809 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2810 procedures: Same as scm_delq_x et al, but delete maximally one
2813 * options.c (scm_options, scm_init_options): GC-protect option
2814 values of type SCM. (Thanks to Telford Tendys.)
2816 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2818 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2819 make sure that there always is a "real" scm_lookupcar.
2821 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2823 * read.c, read.h (scm_read_opts): New read options
2824 "history-length" and "history-file".
2825 (scm_read_options): Stifle history to history length.
2827 * readline.c (scm_read_history, scm_write_history): New procedures.
2829 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2831 * eval.h (scm_macro_eval_x): Removed declaration.
2833 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2834 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2835 Renamed and made global.
2837 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2838 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2840 * evalext.c, evalext.h: New files. Contain non-R5RS things
2841 having to do with evaluation.
2843 * evalext.c (scm_serial_map): New procedure: Version of `map'
2844 which guarantees that the procedure is applied to the lists in
2846 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2847 returns a list of the results of the body forms instead of the
2848 result of the last body form.
2849 (scm_definedp, scm_m_undefine): Moved from eval.c
2851 * evalext.h (scm_m_sequence_to_list): Added declaration.
2853 * macros.c, macros.h: New files.
2854 (scm_procedure_to_syntax, scm_procedure_to_macro,
2855 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2856 scm_macro_name, scm_macro_transformer): Moved from eval.c
2857 (scm_make_synt): Moved from eval.c
2859 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2861 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2864 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2866 * debug.c, print.c: Added #include "macros.h".
2868 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2870 This change adds the ability to use `unread-char' multiple times
2871 without interspersed reads and adds the new procedure
2872 `unread-string'. The change is optimized for the common case of
2873 unreading a single character. This is also the reason behind the
2874 choice to store characters in the port itself: in most cases no
2875 extra malloc is required.
2877 The amount of code in some macros in ports.h has been increased to
2878 the extent that they would fit better as C functions, but, since
2879 this code belongs to the port representation, such functions
2880 should be placed in ports.c which would cause calls back and forth
2881 between ports.c and genio.c. That is not good for performance.
2882 Also, keeping them as macros allows the compiler to do some
2883 optimizations which are needed to make the current interface
2884 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2886 One benchmark (Guile startup time) indicates an increase of
2887 loading speed of 1%. Another (reading (using `read') boot-9.scm
2888 10 times) shows no change in performance.
2890 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2891 made to find a beautiful solution.)
2893 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2894 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2895 character. (SCM_CLRDY clears all.)
2896 (SCM_N_READY_CHARS): New macro: Returns number of unread
2897 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2898 (struct scm_port_table): New fields: `entry' contains port table
2899 index, `cp' points to last unread char, `cbuf' is the buffer for
2900 unread chars, `cbufend' points after end of the character buffer.
2902 * ports.h, ports.c (scm_unread_string): New procedure.
2903 (scm_grow_port_cbuf): New function.
2905 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2907 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2908 to read unread characters. Use SCM_TRY_CLRDY instead of
2911 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2913 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2915 * genio.c, genio.h (scm_ungets): New function.
2917 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2920 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2922 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2923 declarations. (Thanks to Russ McManus.)
2925 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2927 * numbers.c (num2long): As a software archeologist, I'm proud of
2928 this finding! :) Preliminary dating suggests an almost 4 year old
2929 remnant from the SCM ancestor. The sample has been removed from
2930 the finding site and is now safely stored in the repository.
2932 * numbers.h: Removed prototype for num2long.
2934 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2936 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2937 array as second arg.
2938 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2939 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2940 * gh.h: Updated and added prototypes.
2942 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2944 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2946 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2948 * guile-snarf.in: Never generate an empty file. (Thanks to
2951 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2952 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2953 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2954 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2955 gh_new_procedure5_0): Specify argument types, to appease C++
2956 compilers. (Thanks to Brad Bowman.)
2958 Bug reports from Russ McManus:
2959 * guile-snarf.in: If the CPP environment variable is set, use that
2960 as the C preprocessor, instead of the preprocessor autoconf
2962 * snarf.h (SCM_PROC): Cast the function pointer passed to
2963 scm_make_gsubr, to satisfy C++.
2965 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2966 Use the handler passed, instead of ignoring it and using
2967 gh_standard_handler. (Thanks to Etienne Bernard.)
2969 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2971 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2974 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>
2976 * __scm.h, alist.c, async.c, async.h, backtrace.h, chars.c,

2991 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2994 * script.c (scm_compile_shell_switches): Define
2995 use-emacs-interface in the root module, so the repl code can see
2996 it. See today's change to top-repl in ice-9/boot-9.scm.
2998 * filesys.c (set_element, get_element): Make sure that `element'
2999 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
3000 Boekemeier and Jorgen "forcer" Schaefer.)
3002 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
3004 * chars.c (scm_charnames): In ASCII character name table, make
3005 newlines print as #\newline by default, not #\nl.
3007 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
3008 alphabetical order. Oh thrills. But it helps me know how far
3009 along in the compilation I am.
3010 * Makefile.in: Regenerated.
3012 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3014 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
3015 #bytes(...) to #y(...), and syntax for short vectors from
3016 #short(...) to #h(...). This may seem nutty, but, like the other
3017 uniform vectors, byte vectors and short vectors want to have the
3018 same print and read syntax (and, more basic, want to have read
3019 syntax!). Changing the read syntax to use multiple characters
3020 after the hash sign breaks with the conventions used in R5RS and
3021 the conventions used for the other uniform vectors. It also
3022 introduces complexity in the current reader, both on the C and
3023 Scheme levels. (The Right solution is probably to change the
3024 syntax and prototypes for uniform vectors entirely.)
3026 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
3028 Don't use local_fgets on sockets; ftell doesn't work on sockets.
3029 (Thanks to Jorgen "forcer" Schaefer.)
3030 * ports.h (SCM_NOFTELL): New flag.
3031 * fports.c (local_fgets): If it's set, use the generic fgets.
3032 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
3034 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3036 * script.c (scm_compile_shell_switches): Add handling of -q switch
3037 (inhibit loading of user init file).
3038 (scm_shell_usage): Add usage text for -q switch.
3039 (scm_compile_shell_switches): Always load user init file first if
3040 it is loaded at all.
3042 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
3044 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
3045 and is now broken under NetBSD. I can't fathom what it's trying
3046 to do, so I've replaced it with something that I do understand,
3047 which seems to work, and which isn't broken on NetBSD. "Progress?
3048 You Decide." (Thanks to Perry Metzger.)
3050 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
3051 signed/unsigned comparison.
3053 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
3055 Warning fixes from Greg Harvey:
3056 * unif.c (scm_array_set_x): initializer for pos
3057 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
3058 * struct.c (scm_struct_ref, scm_struct_set_x): Added
3059 initializers for field_type, since EGCS so desparately wants to
3061 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
3062 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
3063 when GUILE_DEBUG is defined.
3064 * dynwind.h (scm_wind_chain): Same.
3065 * ports.h (scm_pt_size, scm_pt_member): Same.
3066 * print.h (scm_current_pstate): Same.
3067 * procs.h (scm_make_cclo): Same.
3069 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
3071 Handle short and long long uniform arrays properly. (Thanks to
3073 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
3074 raeql_1): Add cases for scm_tc7_svect (short vectors) and
3075 scm_tc7_llvect (long long vectors).
3077 Change the way libguile and boot-9.scm are timestamped, to try to
3078 get rid of these spurious mismatch warnings. Now both
3079 libguile/versiondat.h and ice-9/version.scm are generated directly
3080 by the configuration process, rather than having version.scm
3081 generated directly, and libguile/versiondat.h generated by the
3082 Makefile, which is generated by configure. It seems that
3083 sometimes the Makefile would change, but versiondat.h depends on
3084 Makefile.in, not Makefile, so it wouldn't get rebuilt.
3085 * Makefile.am (versiondat.h): Target removed; this is generated
3086 directly by the configure script now.
3087 (BUILT_SOURCES): Remove versiondat.h.
3088 * versiondat.h.in: New file, transformed by the configure script
3090 * Makefile.in: Regenerated.
3092 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
3093 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
3094 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
3095 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
3096 if we want to use them in a header file some day, we can. (Thanks
3097 to Michael Livshin.)
3099 * stime.c (scm_get_internal_real_time): Do the arithmetic using
3100 SCM numbers, so we won't have rollover problems; the range of a
3101 signed long in milliseconds is about 25 days. (Thanks to Karl
3104 Don't redefine sleep and usleep; fix this problem now.
3105 * coop.c (sleep, usleep): Remove declarations; we don't use or
3106 redefine these any more.
3107 (scm_thread_usleep, scm_thread_sleep): New functions which do the
3108 job of usleep and sleep in a thread-friendly way. We can use
3109 these in the rest of Guile. Define versions for systems both with
3110 and without iselect.
3111 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
3112 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
3113 we're just using it, not redefining it, we can use a K&R style
3115 (sleep): Declare this, too, if the system hasn't.
3116 (scm_sleep, scm_usleep): Use scm_thread_sleep and
3117 scm_uthread_sleep if they're available; otherwise, just call the
3119 * scmconfig.h.in: Regenerated.
3121 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
3123 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
3125 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
3127 * threads.c: Doc fix.
3129 The argument type of usleep varies from system to system,
3130 as does the return type. We really shouldn't be redefining usleep
3131 at all, but I don't have time to clean that up before the 1.3.
3132 release. It's on the schedule for afterwards. (Thanks to Julian
3134 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
3136 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
3137 * scmconfig.h: Regenerated.
3139 * simpos.c (scm_software_type): Procedure deleted. This isn't the
3140 right way to handle system variation. Autoconf's approach is the
3142 * simpos.h (scm_software_type): Declaration deleted.
3144 * script.c (scm_find_executable): Don't test if unix is #defined
3145 here; first, NetBSD doesn't #define it, and second, it's the wrong
3146 way to go about these things. (Thanks to Perry Metzger.)
3147 (dld_find_executable): Delete this MSDOS support code. This isn't
3148 the way we want to support this; it needs to be rethunk at a
3151 * genio.c (scm_do_read_line): Don't just politely check that the
3152 line was either non-empty or EOF. Abort if it's empty and not
3155 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
3157 * scmconfig.h.in: Regenerated.
3159 * libguile.h: Don't omit the dynamic linking functions. (Thanks
3162 * genio.c (scm_do_read_line): Count lines correctly when the file
3163 doesn't end in a newline.
3165 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
3167 * genio.c (scm_do_read_line): Maintain the line count correctly.
3168 (Thanks to Harvey J. Stein and Greg Harvey.)
3170 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
3173 * numbers.c (big2str): Protect t from garbage collection until
3174 we're done. (Thanks to Gary Houston.)
3176 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
3178 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
3180 * Makefile.in: Regenerated.
3182 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
3183 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
3186 Do magic to mix reads and writes on stdio FILE-based ports.
3187 (Thanks to Christian Lynbech.)
3188 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
3190 (pre_read, pre_write): New functions.
3191 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
3192 local_fputs): Call them.
3193 (local_fflush): Mark the port as ready for reading and writing.
3194 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
3195 flags on new port objects. This might not be accurate --- who
3196 knows what state the FILE * is in when we get it --- but it won't
3197 do extraneous calls to fflush or fseek, so it's no worse than the
3198 behavior before this change.
3199 * ports.h: Add comment.
3201 Centralize the creation of port objects based on stdio FILE * in
3202 fports.c; don't just throw them together anywhere.
3203 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
3204 what the rest of Guile wants. Don't set the revealed count;
3205 that's only appropriate for stdin, stdout, stderr.
3206 (scm_standard_stream_to_port): This function does set the revealed
3208 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
3209 not scm_stdio_to_port.
3210 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
3211 * fports.c (scm_open_file): Same.
3212 * posix.c (scm_pipe): Same.
3213 * socket.c (scm_sock_fd_to_port): Same.
3214 * ioext.c (scm_fdopen): Same.
3215 (scm_freopen): Moved from here to...
3216 * fports.c (scm_freopen): ... here. This is really something that
3217 munges the internals of an fport, so it should go here.
3218 * fports.h (scm_stdio_to_port): Adjust prototype.
3219 (scm_standard_stream_to_port, scm_freopen): New protoypes.
3220 * ioext.h (scm_freopen): Prototype removed.
3222 * filesys.c (set_element, get_element): This can work on both pipe
3223 and file ports, so use SCM_FPORTP to typecheck, instead of testing
3226 * scmconfig.h.in: Regenerated.
3228 Change the definition of the functions in scm_ptobfuns so that
3229 they get passed the port object, not the port's stream.
3230 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
3231 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
3232 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
3233 Pass the port itself to the scm_ptobs function.
3234 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
3235 scm_generic_fgets): Same.
3236 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
3237 getc_void_port, fgets_void_port, close_void_port): Just change the
3238 argument names; these functions don't really do anything.
3239 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
3240 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
3241 port as an argument, and use SCM_STREAM to get the stdio FILE *.
3242 Also, use prototyped definitions, and get rid of the extra
3244 (scm_fptob, scm_pipob): We don't need casts here any more.
3245 * strports.c (prinstpt): Use prototype declarations.
3246 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
3247 and use SCM_STREAM to get the string info. Also, use prototyped
3248 definitions, and get rid of the extra declarations.
3249 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
3252 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
3253 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
3255 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
3256 scm_fgets, for consistency.
3257 (scm_fptop, scm_pipob): References updated.
3259 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
3261 Include the source location in error messages for scripts.
3262 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
3263 stack is still there when we catch the error.
3264 * throw.c (handler_message): If we are handling an error with a
3265 message, then put together the proper arguments and call
3266 scm_display_error, instead of scm_display_error_message. That
3267 displays source location, if it can find it.
3269 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
3271 * gc.c (scm_unprotect_object): Change this so that calls to
3272 scm_protect_object and scm_unprotect_object nest properly.
3273 (scm_protect_object): Doc fixes.
3275 * strings.c (scm_string_set_x): Require the argument to be a
3276 writable string, not a substring or a symbol.
3277 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
3278 (Thanks to John Redford and Charbel Jacquin.)
3280 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
3282 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
3284 * eval.c (safe_setjmp): Remove this misunderstanding.
3285 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
3288 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
3290 * libguile.h: Mark these as C declarations, for compilation by C++
3293 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
3294 __cplusplus clause. I seriously doubt this ever worked the way
3295 the author seems to have intended.
3297 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
3299 Utterly needless cleanups to hopelessly messy code.
3300 * ports.c: Doc fixes.
3301 (scm_fflush): Moved to ...
3302 * genio.c (scm_fflush): ... here, amongst all the other port
3303 method invocation functions.
3304 * genio.h, ports.h: The prototype moves too.
3306 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
3308 * backtrace.c (display_error_body): The current frame does not
3309 always have a parent frame; consider a function called directly
3310 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
3313 * alloca.c (alloca): Undo yesterday's changes, and simply call
3314 malloc directly for storage, and abort if we don't get what we
3315 want. The situation is much simpler --- just call malloc. Emacs
3316 has bizarre/evil requirements (signal handlers might malloc unless
3317 you set this global flag, so you have to set the flag around all
3318 calls to malloc) which we are certainly not going to conform to,
3319 so we can do the simple and obvious thing.
3321 * coop.c (coop_condition_variable_wait): Make this function
3322 static. It's only useful internally --- you should never just
3323 wait on a condition variable.
3324 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
3326 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3328 * unif.c (scm_array_set_x): Accept any kind of number as an
3329 element for a uniform vector of doubles. This is more consistent
3330 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
3332 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
3333 works; I can't conveniently test it myself. (Thanks to Dvid
3334 Tillman for the bug report.)
3336 * init.c: Doc fixes.
3338 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
3339 from here, not from scm_compile_shell_switches (which is a pretty
3340 dumb place to do it).
3341 (scm_load_startup_files): New function.
3342 (scm_ice_9_already_loaded): Variable moved to here from script.c.
3343 * script.c (scm_compile_shell_switches): Don't load the startup
3345 (scm_ice_9_already_loaded): Variable moved.
3346 * init.c (scm_load_startup_files): Prototype for new function.
3347 * gh_init.c (gh_enter): Doc fix.
3349 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3351 Some anti-warning changes from Greg Harvey.
3352 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
3353 warnings when it doesn't understand our NORETURN declarations in
3355 * posix.c (scm_mknod): Similar.
3357 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3359 * posix.c (scm_getpwuid): If we can't find an entry, return our
3360 own message, instead of using scm_syserror --- the getpwMUMBLE
3361 functions don't set `errno' to anything interesting.
3363 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3365 Get rid of warnings from the cooperative threading system.
3366 * threads.h (scm_single_thread_p, scm_yield,
3367 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
3368 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
3369 scm_wait_condition_variable, scm_signal_condition_variable): Add
3370 prototypes for these Scheme-visible functions.
3371 * coop-defs.h (coop_next_runnable_thread,
3372 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
3373 Prototypes for these here, even though they're from iselect.c.
3374 (coop_condition_variable_wait, coop_join): Add prototypes.
3375 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
3376 scm_threads_free_condvar): Make these smob functions static.
3377 * coop-threads.h (coop_init): Give this a real prototype.
3378 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
3379 (coop_next_runnable_thread): No need to provide prototype; it's in
3382 * scmconfig.h.in: .detarenegeR
3384 * iselect.c, threads.c: Doc fixes.
3386 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3388 * Makefile.in: Regenerated with a patched automake, to get
3389 dependency generation right when using EGCS.
3391 * inet_aton.c (inet_aton): Add prototype, to remove compiler
3392 warning. (Thanks to Robert Pluim.)
3394 * inet_aton.c (inet_aton): Reassure the compiler that the
3395 arguments to the <ctype.h> macros are all unsigned characters, not
3398 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3400 Getting rid of more warnings...
3401 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
3402 today's change to ../configure.in.
3403 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
3404 * scmconfig.h.in: Regenertaded.de.,.__
3405 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
3406 (scm_localtime, scm_mktime): Use a const char * to manipulate the
3409 * readline.c: Doc fix.
3410 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
3411 * readline.h (scm_filename_completion_function): Add prototype.
3412 (scm_init_readline): Make this into a prototype.
3414 * readline.c (scm_filename_completion_function): Use SCM_PROC to
3415 declare this, instead of calling scm_make_subr manually.
3417 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
3419 * readline.h (scm_init_readline): Add prototype for this.
3420 (scm_init_readline): Make this a real prototype.
3422 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3424 Warning fixes from Maciej Stachowiak:
3425 * backtrace.h (scm_display_application, scm_backtrace): Add
3427 * debug.c (scm_m_start_stack): Make this function static.
3428 * fluids.h (scm_fluid_p): Add prototype.
3429 * procprop.c (scm_i_procedure_arity): Make this function static.
3430 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3431 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
3432 * root.h (scm_dynamic_root): Add external prototype.
3433 * scmsigs.h (scm_usleep): Add external prototype.
3434 * script.h (scm_init_script): Use prototype, not K&R decl.
3435 * stacks.h (scm_stack_id): Add external prototype.
3436 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3438 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3440 * gh.h: took out the definitions of vset and vref, since they are
3441 replaced by the proper vector routines that correspond to the R4RS
3444 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3446 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3447 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3448 third argument, a C expression that should result in a SCM value,
3449 which is used to initialize the variable. Reimplemented
3450 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3453 * version.h (scm_libguile_config_stamp): Add prototype.
3454 (From Maciej Stachowiak.)
3456 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3458 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3459 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3461 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3463 * print.c (scm_iprin1): Rather than having one i, and using it in
3464 several places, declare a fresh i local to each block where it is
3465 used, and give it a signedness appropriate to its use in each case.
3466 (scm_iprlist): Same.
3468 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3469 comparison warnings.
3471 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3472 signed/unsigned clashes.
3474 * posix.h (scm_tmpnam): Added prototype.
3476 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3477 scm_make_subclass_object): Add external prototypes.
3479 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3480 comparison is okay here.
3482 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3484 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3485 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3487 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3490 * load.c (swap_port): Make this function static.
3492 * load.c (scm_search_path): Make max_path_len and max_ext_len
3493 unsigned, since they're compared against string sizes.
3495 * load.c (init_build_info): Make i unsigned.
3497 * ioext.h (scm_read_line): Add prototype.
3499 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3500 scm_hash_fn_remove_x): Make hash bucket index local variable k
3501 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3502 accurately as possible.
3504 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3505 comparisons, and range checking to make sure those casts are
3508 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3509 signed/unsigned comparisons.
3511 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3512 avoid signed/unsigned comparisons.
3513 * smob.h (scm_numsmob): Change extern declaration to match.
3515 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3516 avoid signed/unsigned comparisons.
3517 * ports.h (scm_numptob): Change extern declaration to match.
3518 (scm_current_load_port, scm_set_port_line_x,
3519 scm_set_port_column_x): New prototypes.
3521 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3522 test code, and it causes warnings.
3524 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3525 gh_uniform_vector_ref): Added prototypes.
3527 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3528 debugging support unconditionally. That's backtrace.c, stack.c,
3529 debug.c, and srcprop.c.
3530 (EXTRA_libguile_la_SOURCES): Omit those from here.
3531 * Makefile.in: Regenerated.
3533 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3535 * options.c (scm_options): Bugfix: Allow empty list of options!
3537 * debug.c, debug.h (scm_single_step): Removed.
3538 (scm_with_traps): New procedure. This procedure could easily be
3539 written in Scheme but needs to be highly optimized.
3541 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3543 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3544 Check SCM_TRAPS_P before trapping.
3546 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3548 Changes to avoid signed/unsigned comparison warnings.
3549 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3550 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3551 so they can have appropriate types for each application. Make i
3552 signed. Use initializers in some spots. I'll probably pay for
3554 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3555 (scm_must_realloc): Make nm unsigned.
3556 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3557 (scm_init_storage): Use prototype-style definition, and make the
3559 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3560 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3562 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3563 avoid signed/unsigned comparison warnings, and because the return
3564 value of readlink may be -1. Don't bother casting the third
3565 argument to readlink.
3567 * filesys.c (scm_dirname, scm_basename): Move these to their own
3568 page, at the end of the file.
3569 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3571 * eval.h (scm_eval_options_interface): Add external prototype for this.
3572 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3574 * eval.c (scm_lookupcar1): Make this static.
3576 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3577 Make these prototype declarations, not K&R-style.
3579 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3580 unsigned comparison warning.
3582 * appinit.c: File removed. It had a single function in it, empty,
3583 whose reason for existence is explained in no documentation or
3584 comment. I think it's there as a default for some Tcl-style
3585 initialization, but Tcl abandoned that approach a while ago.
3586 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3587 (BUILT_SOURCES): Remove appinit.x.
3588 * Makefile.in: Regenerated.
3590 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3592 * Makefile.in: Regenerated using the last public version of
3593 automake, not the hacked Cygnus version.
3595 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3597 Remove Totoro kludge.
3598 * Makefile.in, scmconfig.h.in: Regenerated.
3599 * init.c, readline.c: Don't check if TOTORO is #defined.
3601 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3603 * Makefile.am: Adjust for new thread configuration system.
3604 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3605 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3607 (THREAD_LIBS): Definition deleted; automake will generate such
3608 things automatically.
3609 * Makefile.in: Regenerated.
3611 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3613 Simplify smob and port marking; set the mark bit in the generic
3614 marking code, and make marker routines only responsible for
3615 turning up outgoing pointers.
3616 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3617 before calling the marking function. Don't call the marking
3618 function if it's zero.
3619 * markers.c (scm_mark0): Just return #f. This function isn't
3620 necessary at all now, but it's harmless to call it. We'll leave
3621 it in so other folks' code doesn't croak at link time.
3622 (scm_markcdr): Don't call SCM_SETGC8MARK.
3623 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3624 * dynl.c (mark_dynl_obj): Same.
3625 * root.c (mark_root): Same.
3626 * srcprop.c (marksrcprops): Same.
3627 * unif.c (markra): Same.
3628 * variable.c (scm_markvar): Same.
3629 * ports.c (scm_markstream): Same.
3630 (void_port_ptob): Specify zero for our marking function.
3631 * debug.c (debugobjsmob): Same.
3632 * dynwind.c (guardsmob): Same.
3633 * filesys.c (dir_smob): Same.
3634 * fluids.c (fluid_smob): Same.
3635 * fports.c (scm_fptob, scm_pipob): Same.
3636 * mallocs.c (mallocsmob): Same.
3637 * regex-posix.c (regex_t_smob): Same.
3638 * smob.c (freecell, flob, bigob): Same.
3639 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3640 * throw.c (jbsmob, lazy_catch_funs): Same.
3642 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3644 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3645 scm_copy_tree on code in order not to let memoized code to leak
3646 out. Thus, scm_copy_tree needs to copy vectors as well since
3647 quasiquote can introduce evaluated code also inside vector
3650 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3652 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3654 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3655 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3658 * unif.c: Say that ivect and uvect are of type signed and unsigned
3659 long instead of int in commentary so that it correctly describes
3662 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3664 * stime.c: Removed declaration of strptime. (It should be
3665 declared by the system headers. If it turns out that some systems
3666 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3668 * stime.h: Renamed TIMEH --> STIMEH
3670 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3671 to increase portability, don't use structure assignment.
3672 (Thanks to Nicolas Neuss.)
3674 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3676 (finalize_fd_sets): Added empty statement after last case label.
3677 (Thanks to Nicolas Neuss.)
3679 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3682 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3684 * init.c, readline.c: OK, I won't have these readline.x bug
3685 reports anymore. We've had them since April. The current reason
3686 is a completely unintelligible failure of totoro.red-bean.com to
3687 do the test for rl_getc_function in libreadline correctly. This
3688 kludge overrides the test if we're on totoro so that the snapshot
3689 generation process can work.
3691 * readline.c: Define a strdup replacement if not existent on system.
3693 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3695 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3696 This change makes scm_make_vector R5RS compatible. We cannot keep
3697 the third argument since people want to be able to deduce the form
3698 of the C function call only by looking at R5RS. (At the same time
3699 we have removed some unnecessary complexity!)
3701 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3702 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3703 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3704 argument in call to scm_make_vector.
3706 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3708 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3709 This macro is useful in applications.
3711 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3713 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3714 (scm_parse_path, scm_search_path): New Scheme level procedures.
3716 * load.h (scm_internal_parse_path, scm_parse_path,
3717 scm_search_path): Declared.
3719 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3721 * filesys.c (dirname, basename): New procedures.
3723 * init.c (scm_boot_guile_1): Removed condition around
3726 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3727 new data type (guards) for representation of C level guards and
3728 data on the wind chain.
3729 (scm_internal_dynamic_wind): New function.
3731 * dynwind.h: Declare scm_internal_dynamic_wind.
3733 * root.h (scm_root_state): Added scm_cur_loadp.
3735 * root.c (mark_root): Added comment about cur_loadp.
3737 * load.c: #include "dynwind.h";
3738 (scm_primitive_load): Use scm_inner_dynamic_wind to update
3741 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3743 * ports.c (current-load-port): New procedure.
3745 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3747 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3748 not a tty, return #f.
3750 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3751 to Julian Satchell and Roland Kaufmann.)
3753 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3754 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3756 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3758 * debug.h, debug.c (scm_start_stack): New function. Implements
3759 the guts of old scm_m_start_stack.
3761 * debug.c (scm_m_start_stack): Use scm_start_stack.
3763 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3764 start_stack and restart_stack. (These have static scope.)
3766 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3768 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3769 readline functions to come in release 2.3. (Thanks to Chet
3771 (handle_errors): Use the above functions.
3773 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3775 * readline.c: Improvements for readline support: Handle errors
3776 better; Implement before-read-hook.
3778 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3780 * init.c (scm_boot_guile_1), readline.c: Test for
3781 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3782 assure that we have version >= 2.1.)
3784 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3786 * readline.c (scm_readline): Defer interrupts while we're calling
3789 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3790 away the string to add_history.
3791 (completion_function): Do completion for readline. (Thanks to
3793 (scm_filename_completion_function): New procedure: Filename
3795 (current_input_getc): New function. Use this one instead of
3796 standard getc from readline.
3798 * throw.c, throw.h (scm_handle_by_throw): New function: This
3799 handler throws errors to next handler on the dynwind chain.
3801 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3803 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3806 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3808 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3810 (scm_procedure_properties): Modified to return arity together with
3812 (scm_procedure_property): Added the read-only property `arity'.
3813 (scm_set_procedure_property_x): It is an error to set the `arity'
3816 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3817 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3819 * procprop.h (scm_sym_arity): New symbol.
3821 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3822 to set the dispatch procedure of an operator or entity object.
3824 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3825 Made procedure slots read-only.
3827 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3828 scm_tcs_cons_gloc case in zero args switch; Fixed args
3829 construction for operators in scm_tcs_cons_gloc case in two args
3832 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3834 * fluids.c: Removed use of assert.h (in order to avoid
3837 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3839 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3841 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3842 change makes the evaluator safer at the cost of evaluation speed.
3843 It handles the case when the user has added a non-immediate
3844 improper end of the application form, e.g., `(+ 0 . x)'.
3845 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3846 minimize the extra cost as much as possible. The new code is
3847 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3848 problem with structs planted directly in the code (e.g. by a
3849 macro). This no longer causes segmentation fault. (Thanks to
3852 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3853 arg `proc' in order to be able to throw errors; New argument
3856 * Removed extra #include "debug.h"
3858 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3860 * scmsigs.c: Declare usleep as returning void on some systems.
3861 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3864 * coop.c (usleep): Return void on some systems.
3866 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3868 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3870 * coop.c: Changed return type of usleep to int.
3872 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3873 isn't found in the OS.
3875 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3876 isn't enabled. (Thought that I had made this change ages ago...)
3878 * iselect.c: Declare bzero if not defined by OS.
3880 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3882 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3883 condition. (Thanks to John Tobey.)
3885 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3886 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3889 * __scm.h: Start the long-term project of moving to POSIX threads.
3890 Phase 1: Classification of all critical sections.
3891 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3892 for A sections. (See comments in __scm.h for details.)
3894 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3895 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3897 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3899 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3900 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3901 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3902 dependencies on $(srcdir)/Makefile.in
3903 $(top_builddir)/config.status in order to avoid circularity.
3905 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3906 from argc if argc was 0 initially.
3908 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3909 in generation of libpath.h.
3911 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3913 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3914 libguile from 2 to 3.
3916 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3918 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3920 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3922 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3923 scm_set_port_column_x, scm_port_filename,
3924 scm_set_port_filename_x): Removed optional arguments. Added
3925 proper argument checking.
3927 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3928 stack size in machine words.
3930 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3931 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3932 to Ole Myren Röhne.)
3934 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3936 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3937 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3939 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3942 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3943 procedure apply: Copy argument lists before pushing them unto the
3944 environment so that the environment won't get mutated due to
3945 manipulation of procedure arguments. This should perhaps be
3946 regarded as a temporary solution until someone finds a more
3947 efficient one. (Thanks to Maciej Stachowiak.)
3949 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3951 * script.c (scm_compile_shell_switches): Use "guile" as default
3952 zero arg if argc is NULL.
3954 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3956 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3957 is zero. (Thanks to Dirk Herrmann.)
3959 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3961 * ports.c (scm_add_to_port_table): First line is now line 0
3962 (was 1). (Interface changed according to suggestion by Per
3965 * backtrace.c (display_header): Add 1 to line and column numbers
3966 when presenting them to the user.
3968 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3969 from debug.c --> eval.c
3971 * eval.h, eval.c (scm_eval_options_interface): New options
3973 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3974 i.e. stacks for new threads.
3976 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3978 * eval.c (unsafe_setjmp): Removed with #if 0.
3980 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3983 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3984 to avoid compiler warnings.
3986 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3988 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3990 * throw.c (handler_message): Print message on current error port
3991 instead of default error port. (Thanks to Maciej Stachowiak.)
3993 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3995 * ports.c (scm_add_to_port_table): allocate in units of
3996 struct scm_port_table *, not struct scm_port_table.
3997 * posix.c (scm_close_pipe): remove the port from the port table
3999 Thanks to Rob Engle for both fixes.
4001 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4003 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
4004 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
4006 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4008 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
4010 * backtrace.c (display_error_body, display_backtrace_body),
4011 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
4012 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
4013 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
4014 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
4017 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
4018 don't receive the jmpbuf arg anylonger.
4019 (scm_catch): Don't accept a #f tag.
4020 (scm_throw): Check that key is a symbol.
4021 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
4023 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
4025 * async.c (async_pending): Removed declaration.
4027 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4029 * dynwind.c (scm_wind_chain): New debug function.
4031 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
4032 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
4033 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
4034 extra layer of functions around the body and handler of a thread.
4035 This extra layer makes sure that the handler is called in the
4036 dynamic context of the surround (= empty dynwind list), but under
4037 the *dynamic root* of the body. We can not use the dynamic root
4038 of the surround since that root belongs to another thread => stack
4039 is not handled correctly. It may seem ugly to use this extra
4040 layer, but the extra cost in terms of execution time is really
4041 negligible compared to the total amount of time required to create
4042 a thread, and it would reduce maintainability to duplicate the
4043 crucial and complicated steps performed by cwdr.
4045 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
4046 (SCM_ALLOW_INTS): Added thread switching code before interrupts
4047 get re-enabled. The important effect of this is that interrupts
4048 are blocked during thread switching so that thread data structures
4049 don't risk getting messed up by an unfortunate signal.
4050 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
4051 seems to do more aggressive optimization which actually move
4052 instructions around in these macros in a fatal way. Therefore:
4053 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
4054 just superstitious...)
4055 (SCM_TICK): Maybe do a context switch and take care of asyncs.
4056 This macro should be used instead of SCM_ASYNC_TICK since the
4057 latter doesn't do context switches any more.
4059 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
4060 instead of SCM_ASYNC_TICK.
4062 * coop.c, iselect.c: Since thread switches are now performed with
4063 interrupts masked, we can't use the old mechanism of delivering
4064 signals immediately when they arrive. Signals must instead be
4065 delivered when the asyncs run *after* the end of the critical
4066 section in scm_internal_select. But this also means after context
4067 switch so that the signal will be delivered to a different thread.
4068 To avoid this, I have changed the protocol of
4069 coop_wait_for_runnable_thread and friends so that they are allowed
4070 to return the original thread. So, if a signal arrives during
4071 scm_internal_select, we won't any longer be forced do a context
4072 switch, but can remain in the same thread and deliver the signal
4075 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
4076 scm_asyncs_pending and made it global.
4078 * iselect.c: Small fixes.
4080 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
4081 coop_condition_variable_init, coop_condition_variable_wait,
4082 coop_condition_variable_signal): Changed return type from `void'
4083 to `int'. This is to adhere closer to the pthreads interface.
4084 This, in turn, is part of an attempt to provide C versions of the
4085 mutex and condition variable primitives which can be part of a
4086 frontend to COOP or pthreads.
4088 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
4089 coop_condition_variable_destroy): New functions.
4091 * coop-threads.c (scm_wait_condition_variable): Use
4092 coop_condition_variable_wait_mutex.
4094 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
4095 Definitions moved to coop-defs.h.
4097 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
4098 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
4099 scm_cond_destroy): New C interface to mutecis and cond vars.
4101 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4103 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
4105 * iselect.c: Now several threads can wait on the same file
4106 descriptor. The behaviour is compatible with OS select: All
4107 threads waiting for the fd return with the same status.
4109 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4111 * coop-threads.c, threads.h (scm_spawn_thread): New function.
4112 Can spawn a thread from application C code.
4114 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4116 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
4117 gh_doubles2scm): New functions.
4119 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
4121 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
4122 commented-out version of gh_eval_str()
4124 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
4126 * socket.c (scm_bind): free soka after use.
4128 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
4130 * stime.c (tzvar): new variable.
4131 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
4132 avoid memory leaks when allocating.
4134 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
4136 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
4139 * gc.c, tags.h: Doc fixes.
4141 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4143 * eval.c (macro-eval!): Removed. This function was a design bug.
4144 It allowed memoized code to leak out to the scheme level. Most
4145 things that you could do with `macro-eval!' can be done with
4148 1997-12-20 Tim Pierce <twp@skepsis.com>
4150 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
4151 scm_fgets now depends on ftell(3) to know how many bytes were
4154 1997-12-15 Tim Pierce <twp@skepsis.com>
4156 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
4157 dealing with strings.
4159 1997-12-13 Tim Pierce <twp@skepsis.com>
4161 Make %read-line more suitable for implementing read-line efficiently.
4162 * ioext.c (scm_read_line): Strip the terminating newline from a
4163 string, and return a cons of the string and its terminator.
4165 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
4166 of the string that is read is stored in this memory location.
4167 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
4168 * genio.c, genio.h (scm_do_read_line): Update caller.
4169 * ports.h (scm_ptobfuns): Update typedef.
4170 * fports.c (scm_fptob, scm_pipob): Update struct.
4172 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4174 * filesys.c (set_element): Return file descriptor.
4175 (fill_select_type): Return the highest file descriptor.
4176 (scm_select): Tell select about the highest file descriptor. On
4177 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
4178 Therefore the extra overhead for calculating the maximum fd seems
4179 to be more than compensated. Is this correct? In any case,
4180 scm_internal_select will be much faster with this info.
4181 (scm_select, fill_select_type, set_element): Don't accept any kind
4182 of object in the file descriptor list or vector.
4184 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4186 * iselect.c (finalize_fd_sets): Bugfix.
4188 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4190 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
4191 when using scm_internal_select (since we might switch to another
4194 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
4196 * simpos.c (scm_system): always define: use sysmissing if not
4197 available. Check for HAVE_SYSTEM instead of _Windows (does
4198 Windows lack system or does it have an unusable one?).
4199 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
4200 Let the argument be optional: if not supplied, call system(NULL).
4202 * ports.c (scm_close_port): relax the type check from OPPORTP to
4203 PORTP; closing a closed port is allowed.
4205 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
4207 * fports.c (scm_fgets): Return if the last char in a chunk is
4208 newline. When fgets returns a string whose length is `size-1', it
4209 is ambiguous whether a whole line was retrieved, so we must check
4210 explicitly whether a line terminator is present.
4212 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4214 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
4215 before taking the CDR. (Thanks to Harald Meland.)
4217 * filesys.c (scm_stat): Slightly optimized.
4219 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
4221 * ports.c (scm_close_port): Make sure the port is open before
4224 * guile-snarf.in: Pass args through to gcc in a way that preserves
4225 whitespace boundaries. (Thanks to Greg Badros.)
4227 1997-12-02 Tim Pierce <twp@skepsis.com>
4229 * stacks.c (scm_frame_procedure): Reverse the logic in the return
4230 statement. (Thanks to Doug Evans for pointing this out.)
4232 1997-12-01 Tim Pierce <twp@skepsis.com>
4234 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
4236 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
4238 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
4239 errno macro expansion of this field name. (errno is a C
4240 preprocessor macro on some systems.)
4242 1997-11-29 Tim Pierce <twp@skepsis.com>
4244 * iselect.c: Doc fix.
4246 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
4248 * init.c (scm_start_stack): Removed initialization of
4249 scm_the_last_stack_var.
4251 * backtrace.h: Declare scm_the_last_stack_var.
4253 * backtrace.c: Define scm_the_last_stack_var.
4255 * root.c (mark_root): Don't mark the_last_stack_var.
4257 * root.h (scm_root_state): Removed the_last_stack_var.
4259 * throw.c: Added #include "fluids.h"
4260 (ss_handler): `the-last-stack' is now a fluid.
4262 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
4263 --> the_last_stack_fluid.
4265 * backtrace.c: Added #include "fluids.h"
4266 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
4267 (scm_backtrace): `the-last-stack' is now a fluid.
4269 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
4270 after scm_init_fluids.
4272 1997-11-28 Tim Pierce <twp@skepsis.com>
4274 * iselect.c: #ifdef USE_THREADS around thread-related includes.
4276 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
4277 DLSYM_ADDS_USCORE to decide whether to add an underscore.
4279 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4281 * iselect.c (coop_next_runnable_thread,
4282 coop_wait_for_runnable_thread): Disable interrupts so that no
4283 async is executed before a potential error_revive.
4284 (scm_internal_select): Disable interrupts during the parts of the
4285 code which manipulate the sleep queue and the file descriptors.
4287 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4289 * Makefile.am: Added iselect.c and iselect.h.
4291 * coop.c (coop_qinit): Initialize fields used by
4292 scm_internal_select.
4293 (coop_qget, coop_qget, coop_tmp_queue): Made global.
4294 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
4295 replacement in iselect.c.
4296 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
4297 coop_join): If GUILE_ISELECT enabled, use
4298 coop_wait_for_runnable_thread instead of
4299 coop_next_runnable_thread.
4300 (usleep, sleep): New replacements for system functions if
4301 GUILE_ISELECT is enabled.
4303 * coop-threads.h: Declare coop_wait_for_runnable_thread.
4305 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
4307 * filesys.c: Added #include "iselect.h". Moved FD-macros to
4308 iselect.h. Implement Scheme level `select' using
4309 scm_internal_select. (See NEWS.)
4311 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
4313 * init.c: Call scm_init_iselect.
4315 * iselect.h, iselect.c: New files. Implements
4316 scm_internal_select. (See NEWS.)
4318 1997-11-27 Tim Pierce <twp@skepsis.com>
4320 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
4321 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
4322 and scm_must_free, since ultimately the string returned will be copied
4323 by scm_makfrom0str anyway. Also, read any characters that may have
4324 been pushed onto the port with scm_ungetc.
4325 * ports.c (scm_generic_fgets): Same as for scm_fgets.
4326 * ioext.c (scm_read_line): Free string after Guilifying it.
4327 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
4329 1997-11-26 Anthony Green <green@hoser.cygnus.com>
4331 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
4333 * gh.h: Safely wrap prototypes for c++ usage.
4335 1997-11-25 Mark Galassi <rosalia@cygnus.com>
4337 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
4338 gh_repl (argc, argv).
4340 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
4342 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
4343 and to invoke scm_shell().
4344 (gh_launch_pad): took out the loading of boot-9.scm from here,
4345 since it is probably best to let the user control that. In fact,
4346 gh_repl() now invokes scm_shell() which does that.
4348 1997-11-23 Mark Galassi <rosalia@cygnus.com>
4350 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
4353 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
4355 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
4356 yesterday's underscore patch. (Thanks to Marius Vollmer for
4359 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
4361 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
4362 DLSYM_ADDS_USCORE is not defined.
4364 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
4366 * gh_data.c (gh_uniform_vector_length):
4367 (gh_uniform_vector_ref): started implementing the uniform types in
4370 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
4372 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
4373 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
4375 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
4377 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
4378 configure.in was changed).
4380 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
4382 * Makefile.am (modinclude_HEADERS): Include readline.h here.
4383 * Makefile.in: Regenerated.
4385 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
4387 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
4388 OPORT is an `open' port, not an output port.
4390 * filesys.c (scm_close, set_element, get_element, scm_chown,
4391 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
4392 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
4393 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
4394 scm_close_port, scm_port_line, scm_set_port_line_x,
4395 scm_port_column, scm_set_port_column_x, scm_port_filename,
4396 scm_set_port_filename_x, scm_port_mode,
4397 scm_close_all_ports_except, scm_set_current_output_port,
4398 scm_set_current_error_port): Likewise
4399 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
4400 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
4402 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
4403 * backtrace.c (display_backtrace_body): Likewise
4404 * fports (scm_setvbuf): Likewise
4405 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
4406 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
4407 scm_getpeername, scm_send, scm_sendto): Likewise
4408 * unif.c (scm_uniform_array_write): Likewise
4410 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
4412 Minor problems with substring-related tag changes.
4413 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
4414 exactly what we want to leave in to detect substrings.
4415 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
4416 * tags.h: Fix diagrams and comments describing the S tag bit;
4417 remove vestigial remarks about the D tag bit.
4418 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
4419 * strings.c: Formatting tweaks.
4421 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
4422 variable first; then SCHEME_LOAD_PATH, with a warning message.
4423 (scm_parse_path): New function.
4424 * script.c: Doc fixes.
4426 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
4428 Readline support, from Daniel Risacher.
4429 * readline.c, readline.h: New files.
4430 * init.c: #include "readline.h".
4431 (scm_boot_guile_1): Call scm_init_readline, if we have it.
4432 * Makefile.am (libguile_la_SOURCES): Include readline.c.
4433 * Makefile.in: Regenerated.
4434 * scmconfig.h.in: Regenerated, after change to ../configure.
4436 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4438 * gh.h: gh_vector_set -> gh_vector_set_x
4440 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4442 * gh_data.c (gh_vector_set_x): changed name to make it consistent
4443 with the ! -> _x mapping when going from Scheme to C.
4445 1997-10-19 Mark Galassi <rosalia@cygnus.com>
4447 * gh.h (gh_reverse):
4455 (gh_assoc): added these gh_ functions implemented as macros.
4457 * gh_predicates.c (gh_null_p):
4458 (gh_string_equal_p): added these two missing predicates.
4460 * gh_list.c (gh_append):
4465 (gh_set_cdr_x): added these routines as I go through and try to
4466 complete the picture R4RS functions that should be mirrored in the
4469 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4471 * tags.h (scm_tc7_substring): Changed the comment and code to
4472 conform with the changes below. Folks! We have suddenly two new
4473 free tc7 codes!!! Jummy, jummy!
4475 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
4477 * Makefile.in: Rebuilt.
4478 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
4480 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
4481 * unif.c (scm_vector_set_length_x): Don't handle multibyte
4483 * tag.c (scm_utag_mb_string, scm_utag_mb_substring): Removed.

4496 * tags.h (SCM_TYP7SD): Removed.
4497 (SCM_TYP7D): Removed.
4498 (scm_tc7_mb_string): Removed.
4499 (scm_tc7_mb_substring): Removed.

4504 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
4506 Don't include "mbstrings.h".
4507 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
4508 (SCM_SYMBOL_SLOTS): Define as 4.
4509 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
4510 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,

4530 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
4531 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
4533 1997-10-12 Mark Galassi <rosalia@cygnus.com>
4535 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
4537 * gh_test_c.c (c_vector_test): some improvements on the vector
4540 * gh.h (gh_vector): this used to exist but do the wrong thing.
4541 Now it (almost) does the right thing, though it takes a list
4542 instead of the individual arguments. I need to see how it could
4544 (gh_list_to_vector): added this function as a macro. Corresponds
4545 to Scheme's (list->vector ...).
4546 (gh_vector_to_list): added this function as a macro. Corresponds
4547 to Scheme's (vector->list ...).
4549 * gh_data.c (gh_vector_ref): renamed from gh_vref to
4550 gh_vector_ref, so that it resembles the Scheme routines more.
4551 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
4552 resembles the Scheme routines more.
4553 (gh_make_vector): this used to be (stupidly) called gh_vector().
4554 This is the right name, since it does the same thing as the Scheme
4555 (make-vector ...) procedure.
4557 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4559 * ports.h: #include "libguile/print.h"
4561 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
4562 Some indentation fixes.
4564 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
4565 longer a user field; New field: class_flags.
4567 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
4569 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
4571 * gh_data.c (gh_bool2scm): new function which replaces
4572 gh_int2scmb(), which is now tagged as obsolete.
4574 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4576 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4577 macros should by convention not test for NIMPness.)
4578 (SCM_COERCE_OPORT): Adjust indentation.
4580 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4581 SCM_NIMP test before SCM_PRINT_STATE_P.
4583 * struct.c, struct.h, gc.c: Renamed:
4584 scm_struct_i_layout --> scm_vtable_index_layout
4585 scm_struct_i_vcell --> scm_vtable_index_vcell
4586 scm_struct_i_vtable --> scm_vtable_index_vtable
4587 scm_struct_i_printer --> scm_vtable_index_printer
4588 scm_struct_i_vtable_offset --> scm_vtable_offset_user
4590 * struct.c (scm_print_struct): Use new printer slot; Default
4591 printing: Also output hex code of vtable so that type identity
4592 will be indicated as well.
4593 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4594 Removed struct_printer_var; Removed struct-vtable-offset;
4595 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4596 vtable-offset-user): New constants.
4598 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
4599 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
4600 If this slot contains a procedure, use that to print structures of
4601 the type represented by this vtable.
4603 * print.c (scm_iprin1): Don't print arguments of macro
4604 transformers. (They are always: exp env.); Bugfix: Unmemoize
4605 transformer source with correct environment.
4607 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4609 Streamlining of call-with-dynamic-root:
4611 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
4612 there is now only one catch.
4613 (cwdr_outer_body): Removed.
4614 (cwdr_handler): New function.
4615 (scm_internal_cwdr): New function to perform the function of cwdr
4616 but take args that are more useful to C code. Also, the handler
4617 is now invoked *outside* of the new dynamic root, like the docs
4618 say. We no longer have to catch absolutely all errors, the caller
4619 is responsible for using a handler that does not throw, if he
4621 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4622 * root.h (scm_internal_cwdr): New prototype.
4624 Even more but risky streamlining:
4626 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4627 allocation of the jumpbuf of a root continuation. The changes
4628 below are controlled by it. They are now deactivated.
4629 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4630 the JMPBUF of the scm_rootcont to NULL before returning.
4632 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4633 when they are non-NULL.
4634 (scm_gc_mark): Likewise, mark only when non-NULL.
4636 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4637 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4639 * gc.c (scm_done_malloc): New function.
4640 gc.h (scm_done_malloc): New prototype.
4642 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
4643 (struct scm_print_state) [revealed]: New field.
4644 (scm_print_state_vtable): Make visible to the outside world for
4645 type checking purposes.
4646 (scm_valid_oport_value_p): New prototype.
4648 * print.c (scm_valid_oport_value_p): New function to check whether
4649 a certain value is acceptable as a port argument.
4650 (scm_print_state_vtable): New variable.
4651 (scm_free_print_state): Set `revealed' field to false.
4652 (scm_iprin1): Call user supplied closure printer with
4653 scm_printer_apply. Print in the traditional way when there isn't
4654 one or when it returns #f.
4655 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4656 Accept a port/print-state pair in addition to just a port.
4657 (scm_prin1): Don't return the print_state to the pool when it has
4659 (scm_printer_apply): Set `revealed' field of print_state to true.
4660 (scm_init_print): Set scm_print_state_vtable.
4661 (print_state_fluid, print_state_fluid_num): Removed.
4663 * throw.h (scm_handle_by_proc_catching_all): New prototype
4664 throw.c (scm_handle_by_proc_catching_all): New function
4666 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4668 * Makefile.in: Regenerated with automake 1.2c.
4670 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4672 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4673 was looping endlessly.
4675 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4677 * strports.c (scm_eval_string): Don't close the port.
4679 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4680 former returns a nice normal integer. (Thanks to Daniel
4683 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4685 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4686 makefile variable as a build parameter called LIBS. The
4687 build-guile program will use this, for the time being.
4688 * Makefile.in: Regenerated.
4690 Thanks to Shiro Kawai:
4691 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4692 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4695 * Makefile.in: Regenerated with automake 1.2a.
4697 * script.c (scm_compile_shell_switches): If we hit the -c or --
4698 arguments, don't set the car of (command-line) to scm_usage_name,
4699 the prettified name of the guile executable; give it the full
4700 path, the way shells usually handle $0.
4702 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4704 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4705 Scheme-level name `array-map' and renamed `serial-array-map' to
4706 `serial-array-map!'.
4708 * backtrace.c: Introduced exception handlers which now enclose
4709 `display-error' and `display-backtrace' so that error reporting
4710 won't get into infinite loops if an error occurs during displaying
4711 of the error. This can very easily happen with user supplied
4712 print call-back routines.
4714 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4716 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4717 the names `serial-array-map' and `array-map' should be removed.)
4719 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4721 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4722 Added #include "objects.h"
4724 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4725 Add #include "feature.h".
4727 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4728 (modinclude_HEADERS): Added objects.h.
4730 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4731 This test is needed at many places in the code and should be
4732 abstracted. (Motivated by the need of this test in libguiletk.)
4734 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4735 (scm_eval_string), load.c (scm_primitive_load,
4736 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4737 Use SCM_EOF_OBJECT_P.
4739 * eval.c (scm_init_eval): Add feature `delay'.
4741 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4743 * scmhob.h: Removed.
4745 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4747 * list.h (SCM_LISTn): New macros. Make list creation in C code
4748 prettier. The idea comes from STk.
4750 * sequences.h, sequences.c, append.h, append.c: Removed. These
4751 files implemented non-R4RS operations which would encourage
4752 non-portable programming style and less easy-to-read code.
4754 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4757 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4758 sequences.h, #include append.h.
4760 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4763 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4765 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4767 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4769 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4771 * eval.c: Added #include "objects.h"
4773 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4776 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4777 adjacent smob numbers.
4779 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4781 * procprop.h: Added declaration of scm_i_inner_name.
4783 * gsubr.c: New global symbol scm_i_inner_name.
4785 * debug.c (scm_procedure_name): Try procedure property
4786 `inner-name' if `name' fails.
4788 * print.c (scm_iprin1): Use scm_macro_name.
4790 * eval.c (scm_m_define): Give names to macros as well; Only the
4791 first top-level definition gives a procedure/macro a name.
4792 Otherwise confusing names can turn up in backtraces.
4793 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4794 `name'; Give names to macros as well.
4796 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4797 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4800 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4802 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4804 (prinmacro): Removed. The code has been moved/merged into print.c
4805 in order to decrease code redundancy. We want macros to print in
4806 a way equivalent to procedures, and it would be silly to duplicate
4807 the required code. (We don't want to maintain two places.)
4808 (macrosmob): Print field is now a NULL pointer.
4810 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4811 scm_macro_transformer): New prototypes.
4812 (scm_tc16_macro): Declared.
4814 * print.c (scm_iprin1): Added code for printing of macros. Macros
4815 are now printed in a way equivalent to procedures.
4817 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4819 * procs.h (scm_closure_p): Added declaration.
4821 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4823 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4824 Shouldn't pass "heap" as the subr name.
4826 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4828 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4829 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4830 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4831 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4832 SCM_BOOL_T. Any non-false value is true.
4834 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4836 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4837 scm_gensym): Added prototypes.
4839 * symbols.c (scm_gensym): New function. This will speed up
4840 certain types of applications (such as macro systems) which
4841 generate lots of symbols.
4843 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4845 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4847 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4849 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4850 specifier, since (2) or (2 . 3) would cause SEGV.
4851 (scm_transpose_array): more argument checking fixes.
4853 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4855 * Makefile.in: Regenerated.
4857 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4859 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4861 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4863 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4865 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4867 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4868 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4871 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4872 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4873 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4874 scm_array_p, scm_array_rank, scm_array_dimensions,
4875 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4876 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4877 scm_array_prototype): Added case scm_tc7_wvect.
4879 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4881 * errno.h: prototype for scm_strerror.
4882 * error.c (scm_strerror): new procedure.
4884 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4886 * list.c (scm_list_append_x): Allow non-pair as last argument.
4887 This is consistent with the R4RS append and is probably the
4888 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4890 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4892 * stime.h: prototype for scm_times.
4893 * stime.c (scm_times): new procedure.
4894 * ioext.c (scm_fseek): if the first argument is a file descriptor
4896 (scm_ftell): if the first argument is a file descriptor call lseek
4898 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
4899 * filesys.c (scm_chmod): if the first argument is a file descriptor,
4901 (scm_chown): if the first argument is a port or file descriptor,
4903 (scm_truncate_file): new procedure.
4904 Add DEFER/ALLOW INTS to a few other procedures.
4905 (scm_fsync): new procedure.
4906 (scm_open_fdes): new procedure.
4907 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
4909 (scm_fcntl): the first argument can now be a file descriptor. The
4910 third argument is now optional.
4912 * posix.c (scm_execl, scm_execlp): make the filename argument
4913 compulsory, since omitting it causes SEGV.
4914 (scm_sync): return unspecified instead of #f.
4915 (scm_execle): new procedure.
4916 (environ_list_to_c): new procedure.
4917 (scm_environ): use environ_list_to_c. disable interrupts.
4918 (scm_convert_exec_args): take pos and subr arguments and
4919 improve error checking.
4921 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4923 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4924 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4925 argument to SCM_ASSERT. Furthermore, the name of the function
4926 should be passed as first argument when signalling
4927 SCM_WNA. (Thanks to Thomas Morgan)
4929 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4930 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4931 dispatches on the number of actual args has a default case
4932 reporting an internal error. This is a vestige from a version
4933 that mallocated a SCM vector to hold the arguments. In the
4934 current version this check is too late: if it ever happens we will
4935 have already overstepped the bounds of the array.
4937 Also, the patch [...] adds a check for too many actual arguments."
4939 mdj: Removed check for "internal programming error".
4941 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4943 * gh_io.c (gh_write): New function.
4945 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
4946 throw.c (scm_internal_stack_catch): New sibling to the other catch
4947 functions. Code moved from gh_eval.c.
4948 throw.h: Added header.
4949 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
4950 scm_internal_stack_catch.
4952 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4954 * ioext.h: fix up prototypes.
4955 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
4956 Scheme name is now dup->fdes.
4957 (scm_dup_to_fdes): make the second argument optional and
4958 fold in the functionality of scm_primitive_dup.
4959 (scm_primitive_dup): deleted.
4961 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4963 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
4964 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4965 ultrix are defined. Use setvbuf instead of setbuf.
4966 (scm_setvbuf): new procedure.
4967 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
4968 (scm_setfileno): moved from ioext.c.
4969 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
4970 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
4972 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4974 * fluids.c (scm_fluid_p): New function.
4975 * fluids.h (scm_fluid_p): New prototype.
4977 Sat Jul 26 21:33:37 1997 Marius Vollmer <mvo@zagadka.ping.de>
4979 * print.c (scm_iprin1): Enter printed structures into the print
4980 state as nested data while they are printed.
4981 (print_state_fluid, print_state_fluid_num): New variables.
4982 (scm_init_print): Initialize them.
4983 (scm_iprin): If print_state_fluid carries a print_state, use that
4984 instead of creating a new one.
4985 (scm_printer_apply, apply_stub, struct apply_data): New
4986 definitions to help with calling printer functions written in
4988 * print.h (scm_printer_apply): New prototype.
4990 * struct.c (scm_print_struct): Use scm_printer_apply to call the
4991 user defined struct printer.
4993 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
4994 * fluids.h (scm_internal_with_fluids, scm_with_fluids,
4995 scm_swap_fluids, scm_swap_fluids_reverse): New prototypes.
4996 * fluids.c (scm_internal_with_fluids, scm_with_fluids,
4997 scm_swap_fluids, scm_swap_fluids_reverse): New functions.
4999 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
5001 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
5002 SCM_ASSERT: arg comes before pos.
5004 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5006 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
5007 to a list of length zero correctly.
5009 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5011 Supply an `fgets' method for port objects to do fast line i/o.
5012 * ioext.c (scm_read_line): New function.
5013 * genio.c (scm_gen_read_line): New function.
5014 * fports.c (scm_fgets): New function.

5023 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
5025 * ioext.h: removed scm_duplicate_port prototype.
5027 * ioext.c (scm_primitive_dup2): return the new file descriptor
5028 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
5030 (scm_fdopen): bug fix: don't try to make port unbuffered until its
5031 stream has been set.
5032 (scm_duplicate_port): deleted, there's now an implementation in
5034 (scm_primitive_dup2): do nothing if newfd == oldfd.
5036 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
5038 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
5041 * ioext.h: new prototypes.
5042 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
5044 * fluids.c (next_fluid_num): don't do
5045 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
5047 * ports.h: prototypes too.
5048 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
5050 * fports.h: prototype too.
5051 * fports.c (scm_evict_ports): moved from ioext.c.
5053 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5055 * ports.c (scm_close_port): return a boolean instead of unspecified.
5056 throw an error if an error other than EBADF occurs.
5058 * filesys.h: scm_close prototype.
5059 * filesys.c (scm_close): new procedure, can close file descriptors
5060 and ports (scsh compatible).
5062 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
5065 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
5067 * fluids.c, fluid.h: New files.
5068 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
5069 (modinclude_HEADERS): Added "fluids.h"

5077 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
5078 (scm_make_root): Call scm_copy_fluids to make fluid bindings
5079 unique for the new root when it has a parent.
5081 * smob.h: Include "libguile/print.h" to make scm_print_state
5084 * dynl.c (free_dynl_obj): New function to free the dynamic object
5085 data. (dynl_smob): Use it.
5086 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
5087 the dynamic object data below the linking of the object to avoid
5088 memory leak when the linking code throws an error. Now the code
5089 leaks a whole dynamically linked library when must_malloc throws,
5090 but that should be much less likely.
5092 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
5094 Changes to compile under gnu-win32, from Marcus Daniels:
5095 * stime.c (tzset): If tzset isn't provided, make it a NOP.
5096 (scm_localtime): Change SCM_EOF to SCM_EOL.
5097 (scm_mktime): Likewise.
5098 * socket.c: Don't include sys/un.h unless autoconf tells
5099 us Unix domain sockets are available.
5100 (scm_fill_sockaddr): Ignore Unix domain code.
5101 (scm_addr_vector): Likewise.
5102 (scm_init_addr_buffer): Likewise.
5103 (scm_socketpair): Don't include unless socketpair was
5104 found during autoconf.
5105 * simpos.c (SYSTNAME): Treat cygwin like Unix.
5106 * scmsigs.c (scm_pause): Don't include unless pause was found
5108 * posix.c (scm_getgroups): Don't include unless support function
5109 was found during autoconf (in this case, getgroups).
5110 (scm_setpwent): For setpwent.
5111 (scm_setegid): For setegid.
5112 * net_db.c (scm_inet_netof): Don't include unless support
5113 function was found during autoconf (in this case, inet_netof).
5114 (scm_lnaof): For inet_lnaof.
5115 (scm_inet_makeaddr): For inet_makeaddr.

5127 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
5128 scm_misc_error, not SCM_EOF.
5130 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
5131 arguments for formatting the error message, not SCM_BOOL_F. I
5132 think this is left over from the (eq? '() #f) days.
5134 * read.c (recsexpr): Give this a dummy definition if
5135 DEBUG_EXTENSIONS isn't #defined.
5137 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
5139 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

5149 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
5150 alloca.lo will be included in @LIBLOBJS@. Something better than
5151 this should be possible.
5152 * Makefile.in: Regenerated.
5154 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
5156 * simpos.h: prototype for scm_primitive_exit.
5157 * simpos.c (scm_primitive_exit): new procedure, terminates the
5158 process without unwinding the stack.
5160 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
5162 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
5163 argument and logior its components together, so the user doesn't
5164 have to do this explicitly. Also, if regexp/basic is supplied, then
5165 turn off REG_EXTENDED.
5166 (scm_init_regex_posix): New regexp/basic symbol.
5167 (REG_BASIC): #define this if it is not already present.
5169 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5171 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
5172 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
5173 (CLEANFILES): New target, clean versiondat.h, libpath.h.
5174 (DISTCLEANFILES): New target, clean *.x.
5175 * Makefile.in: Regenerated.

5183 * Makefile.in: Regenerated.
5185 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
5186 flag; I don't think we support it.
5187 (scm_make_regexp): Make sure the user doesn't pass the
5190 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
5192 (scm_init_regex_posix): Define constants for the REG_mumble flags;
5193 name them according to the SCSH convention: regexp/mumble.
5195 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
5197 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
5199 * Makefile.am (libpath.h): Include the values of all the standard
5200 Makefile directory variables. Print a message, but don't print
5202 (versiondat.h): Print a message, but don't print all the commands.
5203 * load.c: #include "alist.h".
5204 (init_build_info): New function.
5205 (scm_init_load): Call it.
5206 * Makefile.in: Regenerated.
5208 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
5210 * root.c: Establish a reliable catch-all handler for the new root.
5211 After all the Scheme handler function might signal an error too,
5212 and we don't want to lose that.
5213 (cwdr_inner_body): Renamed from cwdr_body.
5214 (cwdr_outer_body): New function, to establish the user's handler,
5215 and pass control to cwdr_inner_body.
5216 (cwdr): Establish the reliable catch-all handler here, and pass
5217 control to cwdr_outer_body.
5218 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
5219 the user's handler through to cwdr_outer_body.
5220 * throw.c (scm_handle_by_message): Move guts into....
5221 (handler_message): New static function.
5222 (scm_handle_by_message_noexit): New function.
5223 * throw.h (scm_handle_by_message_noexit): New prototype.
5225 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
5226 across this. Only works on GCC. Otherwise, we hope for the best.
5227 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
5228 the feeling that real thread systems will not need this...
5230 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
5232 Try to detect when people are using one version of libguile and a
5233 different version of ice-9. People have been skewing things and
5234 sending in bug reports.
5235 * Makefile.am (versiondat.h): New file to generate.
5236 * version.c: #include "versiondat.h", to get version info.
5237 (scm_libguile_config_stamp): New function.
5238 * script.c: #include "version.h".

5240 * scmconfig.h.in, Makefile.in: Regenerated.
5241 * Makefile.in: Regenerated.
5243 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
5244 primitive definitions under their Scheme names.
5246 * Makefile.am (libguile_la_LDFLAGS): Update library version to
5247 1:2. Helps avoid confusion between installed and uninstalled libs.
5249 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
5252 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
5253 backslash from definition; this should be used like: GDB_INTERFACE;
5255 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5257 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
5258 new port unbuffered until its stream has been set.
5260 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
5262 * ports.h: new prototype.
5263 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
5265 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
5267 Make things compile neatly under Sun's C compiler.
5268 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
5269 * extchrs.c (xmbtowc): Make the second arg a normal char, not
5270 unsigned, because that's what the ANSI function takes.
5271 * extchrs.h (xmbtowc): Corresponding change to prototype.
5272 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
5274 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
5275 argument plain char *.
5276 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
5278 * tag.c (scm_tag): Remove unreachable statement.
5279 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
5280 top of the word, it should be unsigned.
5282 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
5283 is defined, to avoid warnings; it's only used in the
5284 conflict-checking code. Which might go away anyway.
5285 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
5286 conditionals; put the label definition in an #if too, to stifle
5289 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
5290 ChangeLog-threads in the distribution.
5291 * Makefile.in: Regenerated.
5293 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5295 * guile-snarf.in: Changed regexp to support CPPs that insert
5296 whitespace between lexical tokens (which munges the `%%%' snarf
5299 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5301 * load.c (scm_init_load_path): Append $(datadir)/guile to
5302 %load-path, so modules do not have to be installed in Guile's
5303 current version directory.
5305 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
5307 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
5308 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
5309 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
5310 call the sysdep functions with deferred ints.
5311 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
5312 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
5313 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
5316 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
5319 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
5321 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
5323 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
5325 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
5328 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
5330 * eval.c (scm_lookupcar1): New procedure to cope with a race
5331 condition during lookup (when using threads).
5332 (scm_lookupcar): Implement in terms of scm_lookupcar1.
5333 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
5336 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
5338 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
5339 supplied. (Change from Tim Pierce.)
5341 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
5343 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
5344 23:47:01 1997" changelog: Slots are now initialized with `#f' by
5345 default and not `()'. `#f' is the canonical non-value in Scheme,
5348 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5350 * struct.c (struct_printer): New variable that holds a handle on
5351 the Scheme variable *struct-printer*. This variable can be set by
5352 Scheme code to override the printing of structures.
5353 (scm_print_struct): If struct_printer is set, call it. If it is
5354 not set, or returns #f, print the structure in the old fashion.
5355 Include "eval.h" for scm_apply.
5357 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
5359 * struct.c (scm_struct_ref, scm_struct_set_x): Use
5360 scm_struct_i_n_words to get the number of fields, not
5361 -scm_struct_n_extra_words.
5363 On the route to fancier struct printing:
5364 * struct.c (scm_print_struct): New function to print a structure.
5365 Include "genio.h" to support it. This function doesn't do
5366 anything interesting right now, but I think it should be here
5368 * struct.h: Include "print.h" and add prototype for
5370 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
5371 print structures ourself.
5373 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5375 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
5376 before applying the handler in case it doesn't return.
5378 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
5380 * scmsigs.h, async.h: updated.
5382 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
5385 * posix.c (scm_uname): interpret only negative values as an error.
5386 Solaris normally returns a positive value.
5388 * script.c (scm_compile_shell_switches): if we are not going into
5389 an interactive repl, set scm_mask_ints to zero so that asyncs can
5392 * simpos.c (scm_system): don't ignore/unignore signals around
5395 * posix.c (scm_open_pipe): don't ignore/unignore signals around
5398 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
5399 done in boot-9.scm instead.
5401 * scmsigs.c, async.c: Major rewriting of signal handling code.
5402 (scm_sigaction): new procedure.
5403 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
5405 (scm_raise): return unspecified, throw error on failure.
5407 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5409 * regex-posix.c (scm_init_regex_posix): Register the "regex"
5410 feature, to help boot-9.scm decide whether to import the regex
5413 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5415 * eval.c: Include scmconfig.h at the beginning of the file so that
5416 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
5419 * regex-posix.c: #include "_scm.h" before conditionally #including
5420 <regex.h>; the former defines HAVE_REGCOMP.
5422 * regex-posix.c: #include <regex.h> conditionally, so the file is
5423 CPP'able (for dependency scanning) even on systems that don't have
5426 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5428 Add new R4RS-compliant syntax for keywords.
5429 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5430 regardless of the setting of the `keywords' read option.
5431 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5432 can be re-read no matter what the setting of the `keywords' read
5435 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5437 Add support for POSIX regular expressions.
5439 * regex-posix.c, regex-posix.h: New files. (Some code
5440 is taken liberally from rx/rgx.c in the old Guile dist.)
5442 * init.c: Include regex-posix.h.
5443 (scm_boot_guile_1): Call scm_init_regex_posix.
5445 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5446 Add regex-posix.[ch] sources.
5447 * Makefile.in: Regenerated.
5449 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5450 to do this automatically? It didn't for me, bleh.)
5452 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5454 * fports.c (print_pipe_port): New function.
5455 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5456 latter doesn't even take the right arguments.
5458 * Makefile.am: Increment shared lib revision number. I think
5459 sometimes the uninstalled Guile finds the installed shared lib;
5460 Gord says doing this might help. As things turned out, I can't
5461 say whether it does.
5462 * Makefile.in: Regenerated.
5464 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5465 passing it as the closure argument to scm_boot_guile. (Bill
5468 * ports.c (print_void_port, putc_void_port, puts_void_port,
5469 write_void_port, flush_void_port, getc_void_port, close_void_port,
5470 noop0): Use ANSI prototypes instead of K&R declarations, so the
5471 initialization of void_port_ptob gets aggressively type-checked.
5472 Fix arguments of print_void_port and write_void_port. (Bill

5506 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5508 * script.c (scm_find_executable): Use prototype-style definition
5509 here; apparently it's not quite right to have const in a prototype
5510 and then use a K&R declaration. I wonder if stuff like this will
5511 go away if we compile with -Wrequire-prototypes, or whatever that
5512 is... (Bernard URBAN)
5514 * scmhob.h: New text from Bernard URBAN.
5516 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5518 * script.c: Don't #define const on hpux. Configure takes care of
5519 this. (Thanks to Larry Schwimmer.)
5521 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5522 decide whether to #include <unistd.h>, instead of listing a bunch
5523 of systems. Don't #include stdio twice. Removed dyked-out
5524 definition of scm_find_impl_file.
5526 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5528 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5529 library version info to 1:0.
5530 * Makefile.in: Regenerated.
5532 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,
5533 gdb_interface.h, gdbint.c, gdbint.h, gh_data.c, gh_init.c,
5534 gh_io.c, gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c,

5536 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5537 throw.c: Update copyright years; these files have been worked on
5538 significantly in 1997, but only had copyright years for 1996.
5539 Also, change name of copyright holder on some from Mikael
5540 Djurfeldt to Free Software Foundation; he has signed papers
5541 assigning the changes to the FSF.
5543 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5544 reason not to give the user the option.
5546 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5547 Return #f on end-of-file when scanning table (i.e. when called
5548 with no arguments). Try to catch errors, when we can.
5549 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5551 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5552 external declarations. These are useful.
5554 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5556 * posix.c: don't include <sys/select.h> or define macros for
5557 select, since they were not used in this file.
5559 * filesys.c (scm_select): make the fifth parameter microseconds,
5560 not milliseconds. let the fourth parameter be either a real value
5561 or an integer or #f. The first, second and third arguments can
5562 now be vectors: the type of the corresponding return set will be
5564 (set_element, get_element): new static procedures.
5566 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5568 * strports.c (scm_eval_string): New function.
5569 (scm_eval_0str): Trivially re-implemented in terms of
5571 * strports.h (scm_eval_string): New extern decl.
5573 * net_db.c (h_errno): Add extern decl for this.
5575 * fports.c (local_pclose): New function.
5576 (scm_pipob): Use it in the initializer here.
5579 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5580 Use a meaningful error message when signalling an error. For
5581 this, scm_gethost must check h_errno rather than errno.
5583 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5585 * Makefile.in: Regenerated, using automake-1.1p.
5587 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5589 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5590 not SCM_UNSPECIFIED.
5592 * script.c (scm_compile_shell_switches): don't append (quit) if
5594 (scm_shell): call scm_exit_status and exit on the result of the
5597 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5599 Ensure that shared substrings are handled properly when passed to
5600 a system call or other foreign function. Many thanks to Tim
5602 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5603 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5604 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5605 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
5606 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
5607 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5608 (scm_display_error_message): use RO macros when strings may be RO.
5609 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5610 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5611 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
5612 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
5613 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
5614 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
5615 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
5616 scm_strftime), vports.c (scm_make_soft_port): use
5617 SCM_COERCE_SUBSTR to make sure shared substrings are
5620 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5622 * error.c (scm_error): Add newline to error message.
5624 * init.c (scm_init_standard_ports): Doc fix.
5626 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5628 * dynl-shl.c: Completely replaced with new code from Bernard
5631 * script.c (scm_ice_9_already_loaded): New variable.
5632 (scm_compile_shell_switches): Use it.
5634 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5636 * filesys.c (scm_input_waiting_p): add missing third argument to
5639 * stime.c (scm_localtime): copy the result of localtime before
5640 calling gmtime in case they share a buffer.
5641 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5644 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5646 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5648 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5650 * Makefile.am (check-local): New target, which causes 'make check'
5651 to run gh_test_c and gh_test_repl, with some trivial input.
5652 * Makefile.in: Rgnrtd.
5654 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5656 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5659 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5661 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5662 sure how this was supposed to work.
5663 (scm_async_click): don't send SCM_TICK_SIGNAL.
5664 (scm_init_async): don't initialize %tick-thunk.
5666 * the following change doesn't affect the Scheme interface:
5667 gc-thunk is called at the end of garbage collection. however it's
5668 no longer implemented by pretending it's a signal.
5670 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5671 system async corresponding to scm_gc_thunk.
5672 * async.h: declare scm_gc_async.
5673 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5674 gc-thunk directly, instead of going through a signal handler.
5675 (scm_gc_async): new variable, points to the GC system-async.
5676 (scm_init_async): save the GC async as scm_gc_async instead
5677 of using system_signal_asyncs.
5678 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5680 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
5682 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
5683 Don't screw up if we're interrupted.
5684 * Makefile.in: Regeneradet.
5686 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5688 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5690 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5691 we're not using AM_INIT_GUILE_MODULE any more.
5692 * Makefile.in: Reneregated.
5694 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5696 Functions for finding variable bindings, grace à Tim Pierce.
5697 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5698 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5700 Get 'make dist' to work again.
5701 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5702 * Makefile.in: Regenerated, like a surry without a fringe on top.
5704 Changes for reduced Guile distribution: one configure script,
5706 * configure.in, configure: Removed.
5707 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5708 real configure script lives.
5709 * Makefile.in, scmconfig.h.in: Regenerated.
5711 * init.c: #include "script.h", to get prototype for script.c's
5714 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5716 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5717 scm_must_malloc, not raw malloc.
5719 * script.c (scm_compile_shell_switches): Dyke out debugging output
5722 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5724 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5726 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5727 system has them. Hope this is safe. Previously
5728 sys/timeb.h was included if HAVE_FTIME was defined or if
5729 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5730 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5732 * ioext.c (scm_setfileno): add missing third argument to
5733 scm_misc_error call.
5735 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5737 * eq.c (scm_equal_p): Correctly compare strings of different
5738 varieties. (Thanks to Tim Pierce.)
5740 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5742 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5743 #! block comment must occur on a line all by itself.
5745 Move most of the guts of shell command processing into libguile,
5746 so guile.c can be very small (and eventuallly auto-generated. (I
5747 mean, generated mechanically, not self-generated. Hmm.))
5748 * guile.c, script.c, script.h: New source files.
5749 * init.c (scm_boot_guile_1): Call scm_init_script.
5750 * libguile.h: #include "script.h".
5751 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5752 targets, for new executable.
5753 (libguile_la_SOURCES): Mention script.c.
5754 (modinclude_HEADERS): Add script.h.
5755 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5756 not dynamic linking is enabled. This is because we're generating
5757 executables now. Move CY_AC_WITH_THREADS call after those, so the
5758 values of cy_cv_threads_libs captures the libs chosen above.
5759 * Makefile.in, configure, aclocal.m4: Regenerated.
5761 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5762 We don't maintain this interface any more, and it just confuses
5765 * alloca.c: #include <scmconfig.h>, not <config.h>.
5766 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5767 it'll get included in disties.
5769 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5771 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5772 be distributed, because they confuse people.
5773 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5775 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5777 * configure.in: check for presence of gethostent (not present on
5778 OpenBSD by default).
5779 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5780 * configure, scmconfig.h.in: Regenerated.
5782 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5784 * backtrace.c (scm_backtrace): Split message string across
5785 newlines properly. GCC is more tolerant of this than other
5788 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5790 Merge threads directory into libguile.
5791 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5792 threads.h: New source files.
5793 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
5794 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5796 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5797 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5798 coop-threads.c.cygnus, coop-threads.h.cygnus.
5799 * configure.in: If we're using threads, include threads.o in
5801 * _scm.h, libguile.h: threads.h lives in this directory now.
5802 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5803 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5804 currently used, but brought along for information's sake.
5805 * ChangeLog-threads: log from old 'threads' directory.
5806 * Makefile.in, configure: Rebuilt.
5808 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5810 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5813 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5815 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5817 Merge GH interface library into libguile.
5818 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5819 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5820 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5821 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5823 (EXTRA_libguile_la_SOURCES): ... here.
5824 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5825 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5826 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5827 New variables, describing how to build the gh test programs.
5828 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5829 build the test programs, and we probably should have been linking
5830 libguile.la against them all along, to support AIX shared libs.
5831 Add cflags for threads to CFLAGS; add libs for threads to new
5832 variable THREAD_LIBS, used in Makefile.am.
5833 * ChangeLog-gh: log from old `gh' subdirectory.
5834 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5836 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5838 * acconfig.h: Undo change of Apr 9; including the definition of
5839 PACKAGE in the guile headers conflicts with applications' own
5841 * scmconfig.h.in: Regenerated.
5843 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
5845 * filesys.c (scm_fcntl): New function from Roland McGrath.
5846 (scm_init_filesys): New symbols for use with fcntl.
5847 * filesys.h: Added prototype.
5849 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
5850 when PROC is receiving no arguments.
5852 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5854 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5855 have S_IFSOCK. This is the case under Ultrix.
5857 * posix.c (scm_status_exit_val, scm_status_exit_val,
5858 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5859 Ultrix versions of WIFSTOPPED, etc., which assume that their
5860 arguments are lvalues (hmm).
5862 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5864 * eval.c: Doc fixes.
5866 * throw.c: Doc fixes; rearranged.
5868 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5870 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5872 * acconfig.h: Added entry for PACKAGE.
5873 * scmconfig.h.in: Regenerated.
5875 Changes to work with automake-1.1n, which has better libtool support.
5876 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5877 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5879 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5881 * Makefile.in: Rebuild.
5883 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5885 * stime.c (scm_mktime): take an optional zone argument.
5886 (scm_localtime): check putenv return value.
5887 (scm_strftime, scm_strptime): moved from posix.c. move #include
5889 stime.h, posix.h: update prototypes.
5890 (bdtime2c, setzone, restorezone): new static procedures.
5891 (scm_mktime, scm_strftime): use them.
5892 (scm_strftime): don't call mktime before strftime. Use
5893 filltime for return value.
5894 (filltime): convert NULL zname to #f.
5895 (scm_strptime): return a count of characters consumed, not
5896 the remaining string.
5898 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5900 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
5901 (scm_mktime): likewise.
5903 Uncomment localtime and mktime.
5905 * configure.in: add AC_STRUCT_TIMEZONE.
5907 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5909 * stime.c (scm_init_stime): don't define ticks/sec.
5910 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5911 return value problem and is still portable.)
5913 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5915 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5916 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5917 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5918 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5919 cpp_err_symbols.c): Corresponding changes.
5920 * Makefile.in: Regenerated.
5922 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5924 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5925 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5926 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5927 * putenv.c: new file, from sh-utils 1.12.
5929 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5930 since allocation isn't for Scheme objects.
5931 (scm_putenv): copy strings before placing in the environment.
5933 * stime.c (scm_current_time): throw an error if time returns -1,
5934 instead of returning #f.
5935 (scm_get_internal_real_time, scm_get_internal_real_time): use
5936 scm_long2num for return value instead of SCM_MAKINUM.
5938 * stime.h: prototypes updated.
5940 * stime.c (scm_time_in_msec): apparently unused, deleted.
5942 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5944 * configure.in: check for gettimeofday.
5946 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5947 which may be more usefully portable than a gettimeofday interface.
5949 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5951 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5953 * Makefile.in: Regenerated.
5955 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5957 * stime.c (filltime): recovered static procedure.
5958 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5961 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5962 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5964 * posix.c (scm_mknod): split the mode argument into type and perms
5965 arguments, like the extra fields returned by stat.
5967 * fports.c (scm_pipob): set the close, free and print procedures.
5968 (scm_close_pipe): new procedure.
5970 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5971 define them in boot-9.scm
5973 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5975 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5976 wan't defined. Don't include fd.h.
5978 * Previously fd.h was regenerated whenever configure was run,
5979 forcing a couple of files to be recompiled.
5981 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5982 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5983 Check for _fileno as well as _file.
5985 * ioext.c: don't fd.h.
5986 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5989 * Change the stratigy for getting information about errno
5990 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5991 generating lists of symbols during the build process, which will
5992 not always work, include comprehensive lists in the distribution.
5993 To help keep the lists up to date, the "check_signals" and
5994 "check_errnos" make targets can be used.
5996 * configure.in: don't check for a command to extract errno codes.
5997 * Makefile.am: update file lists, remove errnos.list and errnos.c
5998 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5999 check_errnos targets.
6000 (CLEANFILES): remove errnos.c and errnos.list, add
6001 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
6002 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
6003 * errnos.default: deleted.
6004 * cpp_signal.c: new file.
6005 * cpp_errno.c: renamed from errnos_get.c.
6006 * cpp_err_symbols, cpp_sig_symbols: new files.
6007 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
6008 * error.c (scm_init_error): #include cpp_err_symbols instead of
6010 * posix.c (scm_init_posix): don't intern signal symbols. #include
6013 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
6015 * strop.c (scm_i_index): allow the lower bound to be equal to the
6016 length of the string, so a null string doesn't always give an error.
6018 * posix.h: new prototypes.
6019 * posix.c (scm_status_exit_val, scm_status_term_sig,
6020 scm_status_stop_sig): new functions, as in scsh. They break down
6021 process status values as returned by waitpid.
6023 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
6025 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
6026 configure doesn't know about it.
6028 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6030 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
6032 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
6033 which defines C variables with global linkage.
6035 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6037 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
6040 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
6042 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
6043 has time to check why this doesn't work well with continuations.
6045 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
6047 * Fix shell syntax error; some shells won't tolerate
6048 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
6050 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
6052 * posix.c (scm_uname): throw an error if uname fails instead
6055 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
6057 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
6060 * async.c (scm_ints_disabled): definition moved from error.c.
6062 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6064 * acconfig.h: Removed PACKAGE.
6066 * scmconfig.h.in: Regenerated.
6068 * snarf.h: g++ says it's non-portable not to specify the first
6069 argument in a varargs declaration. I introduced the first
6070 argument by using preprocessor conditionals.
6072 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
6074 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
6075 (scm_freopen): use RO string macros for filename and modes.
6076 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
6078 * posix.c (scm_getgrgid): simplify conversion of name to C string.
6079 (scm_mknod): use RO string macros for path.
6081 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
6082 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
6084 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
6085 use SCM_ROSTRINGP and SCM_ROCHARS.
6087 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6089 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
6092 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
6093 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
6094 support for byte vectors.
6096 * print.c (scm_iprin1): Limit number of vector elements printed
6097 according to pstate->length.
6099 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6101 * backtrace.c (scm_display_error_message): don't segv if message
6104 * error.h: prototype for scm_error_scm.
6106 * error.c (scm_error_scm): new procedure, reimplements scm-error
6107 in C and uses scm_error.
6109 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6111 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
6112 pointer to the Scheme variable read-hash-procedures and intern it
6113 in scm_init_read. Modify scm_read_hash_extend and
6114 scm_get_hash_procedure to use the pointer.
6116 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6118 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
6119 (SCM_KEYWORD_STYLE): defined.
6121 * read.c (scm_read_opts): add a keywords option. This isn't a
6122 boolean option, in case someone wants to add support for DSSSL
6124 Setup scm_keyword_prefix symbol.
6125 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
6127 I've left keyword support disabled by default, since it doesn't
6128 seem to break the module system and it gives R4RS standard behaviour.
6129 It can be reactivated with (read-set! keywords 'prefix).
6131 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6133 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
6134 before constructing arbiter.
6136 * eval.c (scm_m_define): Bugfix: Check that the object is a
6137 closure before setting the procedure property!
6139 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
6141 * ports.c: Removed `ungetc-char-ready?'.
6143 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
6145 * read.c (scm_init_read): intitialise scm_read_hash_procedures
6146 (idea from Mikael: make it a pair so scm_permanent object only
6148 (scm_read_hash_extend): don't call scm_permanent_object.
6149 (ideas from Mikael): if chr is already in the list, replace its
6150 procedure instead of appending it again. If proc is #f, remove
6152 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
6154 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
6156 * gdbint.c (gdb_read): update scm_lreadr usage.
6158 * load.h: update prototypes.
6160 * load.c (scm_primitive_load, scm_read_and_eval_x,
6161 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
6163 * read.h: add prototype for scm_read_hash_extend. Change args for
6166 * read.c (scm_read_hash_procedures): new variable.
6167 (scm_read_hash_extend): new procedure.
6168 (scm_get_hash_procedure): new procedure.
6169 (scm_lreadr): use scm_get_hash_procedure instead of an argument
6170 for extended # processing.
6171 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
6172 scm_read_token): remove case_i, sharp arguments. Change callers.
6174 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
6176 * read.h (SCM_N_READ_OPTIONS): increase to 3.
6177 (SCM_CASE_INSENSITIVE_P): define.
6179 * read.c: add case-insensitive option to scm_read_opts.
6180 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
6181 to determine whether to convert symbol case.
6182 (default_case_i): definition removed.
6183 * read.c (scm_read_token): if case_i, downcase ic before doing
6186 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6188 * configure.in: Added configuration option `guile-debug'.
6189 Configure with --enable-guile-debug if you want a bunch of extra
6190 functions used for debugging when developing Guile.
6192 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
6194 * procs.c (make-cclo): New undocumented debugging procedure: Make
6195 compiled closure with internal procedure PROC and length LENGTH.
6196 Only compiled if GUILE_DEBUG is defined.
6198 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
6200 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
6202 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
6204 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
6205 with 3 or more args internally to the evaluator.
6207 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6209 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
6210 with 3 or more args internally to the evaluator. This is mainly
6211 because we don't want to pass entry and exit points of the
6212 debug support twice, but it also seems to increase the speed of
6213 the evaluator for such calls (e. g. (+ 1 2 3)).
6215 * backtrace.c (scm_display_application): New procedure:
6216 display-application; Set fancy printing parameters individually
6217 for different types of display (backtrace, error, application).
6218 (These should of course be customizable!)
6220 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
6221 clear the CHECK-flags.
6223 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6225 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
6227 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6229 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
6230 from pairs with a GLOC in the car.
6232 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
6233 otherwise `symbol-hash' will behave badly.
6234 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
6235 we get segmentation fault!
6237 * symbols.c: Added #include "weaks.h". New functions:
6238 `builtin-bindings' and `builtin-weak-bindings'. (These will be
6239 moved to an extraneous library when we split libguile.)
6241 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6243 * filesys.c (scm_stat): stat now takes fport arguments too as
6244 documented in the manual.
6246 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6248 * debug.c (scm_single_step): Bugfix: Call continuation with
6249 scm_call_continuation instead of throwing to it.
6251 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
6253 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
6254 argument wasn't declared to be optional.
6256 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6258 * stime.c (scm_init_stime): Add feature "current-time".
6260 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6262 * throw.h: prototype for scm_exit_status.
6263 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
6264 args to derive an exit status. Allows (quit) to work from a
6266 (scm_exit_status): new function.
6269 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6271 * eval.c (scm_deval): Removed some old code.
6272 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
6274 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
6277 * symbols.c (msymbolize): Bugfix: Must initialize property list to
6280 * procs.c: Introduce the existent C function scm_thunk_p at the
6281 Scheme level as well.
6283 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6285 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
6286 used from C to easily lookup the value of a symbol in the current
6289 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6291 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
6292 scm_init_unif in this file. This will also fix a previous problem
6295 * configure.in: Added AM_MAINTAINER_MODE
6297 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6299 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
6302 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6304 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
6305 source files that are not always included in libguile but should
6306 have their dependencies calculated by automake. This variable is
6307 recognized by automake, no further magic is needed.
6308 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
6309 to deal exclusively with *.lo files, as it seems. The *.o files
6310 are built automatically when the corresponding *.lo file gets
6313 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
6315 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
6318 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
6320 * unif.c (scm_array_set_x): minor change to argument error checking.
6322 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
6324 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
6325 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
6326 They should only be included in the library at configure.in's
6328 (libguile_la_LDADD): Include the appropriate .lo files here.
6329 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
6330 so we know when to build them (and their .lo bretheren).
6331 * configure.in (LIBLOBJS): New substituted variable. We let
6332 configure decide which .o files to include in LIBOBJS, and then
6333 put the corresponding list of .lo files in LIBLOBJS. The latter
6334 is what we pass to libtool.
6335 * Makefile.in, configure: regenerated.
6337 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
6339 * symbols.c (scm_sysintern0): New function. Contains the core of
6340 old scm_sysintern but doesn't take a second value argument.
6341 (scm_sysintern): Now uses scm_sysintern0.
6342 (scm_sysintern_no_module_lookup): Renamed to
6343 scm_sysintern0_no_module_lookup and doesn't take a second value
6344 argument any longer.
6346 * symbols.h (scm_sysintern0: Added declaration.
6348 * options.c (scm_init_opts): Use scm_sysintern0 instead of
6349 scm_sysintern when interning option keys. Otherwise we risk
6350 destroying the values of already interned variables.
6352 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
6353 scheme-level boolean (use SCM_NFALSEP).
6355 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
6357 (scm_backtrace): New function. (C version of old function from
6358 boot-9.scm) Motivation: Make it possible to display backtraces
6359 without depending on boot-9.scm. (I'm uncertain if this
6360 motivation is good enough...)
6362 * root.h (scm_root_state): Add member the_last_stack_var.
6363 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
6365 * root.c (mark_root): Mark scm_the_last_stack_var.
6367 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
6370 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
6372 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
6373 1. mark_lazy_catch didn't mark the smob.
6374 2. Both functions above have standard variants:
6375 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
6376 free_lazy_catch --> scm_free0.
6378 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
6380 * throw.c (scm_internal_lazy_catch): New function.
6381 (scm_lazy_catch): Rewritten to use it.
6382 (scm_ithrow): Handle the new lazy catch representation.
6383 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
6384 that doesn't have a jmpbuf is a lazy catch clause.
6385 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
6386 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
6387 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
6389 (scm_init_throw): Register the new lazy-catch smob type.
6390 * throw.h (scm_internal_lazy_catch): decl for new function.
6392 * throw.c (scm_internal_catch): Doc fixes.
6394 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
6395 configure.in. Including this might cause problems if applications
6396 that link against libguile include their own copies of alloca, but
6397 if they're using autoconf, they should be adding libguile to LIBS
6398 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
6399 the copy in libguile, and things will be okay. (I think.)
6401 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6403 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
6405 strop.h: move prototypes too.
6407 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6409 * posix.c (scm_init_posix): don't intern EINTR since it's now done
6412 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
6413 etc. I deleted them from filesys.c long ago, but didn't
6414 notice they were here too (although ineffective since
6415 sys/stat.h wasn't included).
6417 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
6419 * eval.c: Don't define alloca in GCC case. gcc will automatically
6420 use __builtin_alloca if appropriate.
6422 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6424 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6425 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6426 that values of automatic variables are preserved. See comments
6427 for safe_setjmp for details.
6429 Change from Thomas Morgan:
6430 * variable.c: Include eq.h.
6431 (var_equal): New function.
6432 (variable_smob): Use var_equal as the discriminator for variables.
6434 * throw.c (s_throw): Remove extraneous declaration.
6436 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6437 * eval.c: Add necessary CPP cruft to support that.
6438 * configure, Makefile.in, scmconfig.h.in: regenerated.
6440 Change from Thomas Morgan:
6441 * procprop.c (scm_procedure_properties): Convert the Scheme
6442 boolean returned by scm_procedure_p into a C boolean before using
6443 it as a condition for SCM_ASSERT.
6444 (scm_procedure_property): Likewise.
6446 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6447 indications of Unixness.
6450 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6452 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6454 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6456 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6457 "unknown # object" error messages.
6459 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6460 (scm_i_index) and declare it static. Add a 'direction' argument
6461 to indicate what way the search should go.
6462 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6464 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6465 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6467 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6469 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6471 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6472 to avoid clash with various scsh forks.
6474 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6476 The following two changes (ramap.c, throw.c) are motivated by the
6477 apparent unportability of forward declarations of static arrays of
6478 the form `static foo bar[];'.
6480 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6481 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6483 * throw.c (scm_throw): Moved above scm_ithrow.
6485 * options.h: Removed the extern declarations of scm_yes_sym and
6486 scm_no_sym since these are static.
6488 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6490 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6492 * Makefile.am: remove AWK=@AWK@.
6493 Add a rule for generating errnos.list.
6494 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6496 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6497 don't extract errnos, just set a variable (avoids the
6498 need to recompile error.c just because configure is run.)
6500 * unif.h: update prototypes.
6501 * unif.c (scm_uniform_array_read,write): change the offset and
6502 length arguments to start and end, for consistency.
6504 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6506 * ioext.h: update prototypes.
6507 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6508 scm_read_line_x, it's a more general procedure using an
6509 interface from scsh. read-line and read-line! are now defined
6511 Note that the new read-line trims the terminator
6512 by default, previously it was appended to the returned string. An
6513 optional argument specifies how to process the terminator (scsh
6514 compatible). For the old behaviour: (read-line port 'concat).
6515 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6516 returns a pair, but is converted to multiple values if the scsh
6519 socket.h: update prototypes.
6520 * socket.c (scm_recvfrom): for consistency with other procedures,
6521 take start and end as separate optional arguments.
6522 (scm_recv, scm_recvfrom): don't allow the second argument
6523 to be a size, only a buffer. Change the scheme names to
6524 recv! and recvfrom!. Don't return the buffer.
6526 * ioext.h, posix.h: move prototypes too.
6527 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6528 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6529 "read.h" and "unif.h".
6530 * ioext.c: include "chars.h"
6532 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6534 * dynl.c: The dynamic linking and module registration functions
6535 are now defined even when dynamic linking is not available for the
6536 host system. Some of their functionality can be done without
6537 dynamic linking; when it's really needed, they throw errors.
6539 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6541 * configure.in: Only define DYNAMIC_LINKING when one of the system
6542 dependent functions is detected.
6543 * dynl.c (scm_dynamic_func): New function to get the address of a
6544 function in a dynamic object.
6545 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6546 produced by scm_dynamic_func as the thing to call.
6548 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6550 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6551 (scm_register_module_xxx, scm_registered_modules,
6552 scm_clear_registered_modules): New functions.
6554 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6556 * symbols.c (scm_sysintern): Renamed to
6557 scm_sysintern_no_module_lookup.
6558 (scm_sysintern): New function to take the place of the old
6559 scm_sysintern. It uses the current toplevel lookup closure to give
6560 the symbol its value. This is a temporary hack to put packages
6561 like gtcltk into their own module.
6562 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6563 us whether `scm_top_level_lookup_closure_var' has been initialized
6565 * eval.c (scm_init_eval): Set it.
6567 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6569 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6570 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6572 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6574 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6575 scm_sys_dup): deleted: FD capability will be added to other
6577 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6578 scm_fd_free, fd_smob, scm_intern_fd.
6579 (scm_open): renamed from scm_sys_open. Return a port instead of
6580 an FD object. Make the mode argument optional.
6581 (scm_sys_create): deleted, it's just a special case of open.
6582 (scm_init_filesys): move interning of constants O_CREAT etc.,
6583 here (were previously using SCM_CONST_LONG macro).
6584 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6586 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6587 include "fports.h" and <stdio.h>
6588 (scm_stat, scm_select): don't support FD objects.
6590 * error.h: adjust scm_syserror_msg prototype.
6591 * error.c (scm_syserror_msg): take an extra argument for errno.
6592 Using the global value didn't always work, since it could be
6593 reset by procedure calls in the message or args arguments.
6595 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6596 I don't understand why the check was there (and what about the
6599 * strop.c (scm_string_copy): allow shared substrings to be copied.
6601 * unif.h: corresponding change to prototypes.
6602 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6603 recognize two new optional arguments: offset and length. Allow
6604 the port argument to be an integer (file descriptor, for scsh).
6605 Include <unistd.h> for "read" prototype.
6607 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6609 * socket.c: don't include filesys.h.
6611 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6613 * Makefile.am: add AWK=@AWK@ (?)
6615 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6617 Add a rule to generate errnos.c from errnos.
6618 * error.c (scm_init_error): include errnos.c.
6619 * errnos_cnvt.awk: new file, converts the list of errno codes to
6621 * errnos_get.c: new file.
6622 * errnos.default: new file, contains errnos to try if they can't
6623 be extracted from errno.h.
6624 * configure.in: if using GCC, try and extract errno codes from
6628 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6630 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6631 * Makefile.am: Made libguile into a libtool library.
6632 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6633 Set libtool_libs to indicate that libguile is a libtool library.
6634 See guile/ChangeLog for details.
6635 * .cvsignore: ignore "*.lo", the libtool library objects.
6637 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6639 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6640 use htons in getservbyport argument.
6642 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6644 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6645 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6648 * objprop.c (scm_object_property): No need to take the CDR of the
6649 value returned by scm_object_properties, since Aug 20 change.
6651 * configure.in: When checking for struct linger, #include
6652 <sys/types.h> as well as <sys/socket.h>. I've never known
6653 <sys/types.h> to cause any portability problems, and Solaris's
6654 <sys/socket.h> needs it.
6655 * configure: Rebuilt.
6657 I think the Sun compiler has chosen a perverse way to interpret
6658 ANSI declarations combined with K&R definitions. We'll
6659 appease it a little bit. But when it invades France, we fight.
6660 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6661 * print.h (scm_iprlist): Here too.
6662 * numbers.c (scm_divbigdig): Change definition to match
6663 declaration in numbers.h.
6664 * unif.c (scm_makflo): Change definition to match declaration in
6667 * init.c (scm_boot_guile): Don't return the value of
6668 scm_boot_guile_1. This function doesn't return a value;
6669 scm_boot_guile_1 doesn't return a value (or return at all).
6671 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6674 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6675 compile. I have a feeling this function is a bad idea anyway ---
6676 one should always test for features, not systems.
6678 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6679 semicolons. Only pure luck kept this from being noticed earlier.
6681 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6683 * socket.c (scm_recvfrom): Added missing semicolon.
6685 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6687 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6688 the buffer and start and end positions for scsh networking
6691 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6693 * configure.in: Revert previous change to this file; the problem
6694 is due to transient automake weirdness.
6695 * configure: Rebuilt.
6697 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6698 PLUGIN/guile.libs. configure generates the latter from the former.
6699 * Makefile.in: Rebuilt.
6701 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6702 need this if we install scripts, like guile-snarf.
6703 * configure: Rebuilt.
6705 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6707 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6709 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6711 * socket.c (scm_addr_vector): fix faulty scm_listify.
6713 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6715 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6716 style block comment is no longer considered an error.
6718 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6720 * PLUGIN/guile.libs.in: New file.
6721 * PLUGIN/guile.libs: Removed from repository.
6722 * configure.in: Create PLUGIN/guile.libs from
6723 PLUGIN/guile.libs.in. This is for including additonal libraries
6724 needed for dynamic linking.
6725 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6726 instead of PLUGIN/guile.libs.
6728 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6730 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6732 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6733 occurrences of the given element from the list, not just the
6734 first. This is how the Emacs Lisp functions behave, how the
6735 analogous Common Lisp functions behave, and (I believe) how the
6736 older Maclisp functions worked. I realize that this change may
6737 break code, but it seemed better to break it before the Guile
6740 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6741 Their prototypes were already present in gc.h, but they weren't
6743 (scm_init_storage): Initialize scm_protects.
6744 * root.c (scm_protects): New element of scm_sys_protects.
6746 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6748 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6750 * libguile.h: Added #include "libguile/net_db.h".
6752 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6753 30 change. That file is only meant for communication between the
6754 configuration process and load.c. If code linked against libguile
6755 wants to get at the paths mentioned in libpath.h, it can call
6756 functions declared in load.h.
6758 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6760 * libguile.h: Removed #include "libguile/fdsocket.h"
6762 * net_db.c: Added #include <sys/socket.h>.
6764 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6766 * filesys.c (scm_input_waiting_p): use select in preference to
6767 FIONREAD, since the latter doesn't detect EOF.
6768 Throw error if neither select nor FIONREAD available.
6770 * socket.c (scm_connect): take a port, not a fd object.
6771 (scm_fill_sockaddr): throw an error if fam is not recognised.
6772 (scm_bind): use scm_fill_sockaddr.
6773 (scm_listen): take a port, not a fd object.
6774 (scm_accept): take and return a port. return #f in the car if
6775 address can't be got
6776 (scm_sock_fd_to_port): new procedure.
6777 (scm_socket): use scm_sock_fd_to_port.
6778 (scm_addr_vector): throw error if unrecognised address type.
6779 take an extra argument with the calling procedure name.
6780 (scm_getsockname): take a port. return #f if address can't be got.
6781 (scm_getpeername): take a port. return #f if address can't be got.
6782 (scm_recvfrom): take a port. return #f for address component if can't
6784 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6785 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6787 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6789 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6790 use separate data pointers, to allow them to be designed
6791 independently and reused.
6792 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6793 Renamed from catch_body, catch_handler, and uncaught_throw; made
6795 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6797 (scm_catch): Use the above.
6798 (scm_throw): Don't bother printing a message for an uncaught
6799 throw; we establish a default handler in init.
6800 * throw.h (scm_internal_catch): Prototype updated.
6801 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6803 (struct scm_body_thunk_data): New structure, used as data
6804 argument to scm_body_thunk.
6805 * init.c (struct main_func_closure): New structure, packaging up
6806 the data to pass to the user's main function.
6807 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6808 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6809 scm_internal_catch to establish a catch-all handler, using
6810 scm_handle_by_message. This replaces the special-case code in
6812 (invoke_main_func): Body function for scm_internal_catch; invoke
6813 the user's main function, using the main_func_closure pointer to
6814 decide what to pass it.
6815 * root.c (struct cwdr_body_data): Remove handler_proc member.
6816 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6817 (cwdr_handler): Removed.
6819 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6821 * socket.h (SCM_P): update bind prototype.
6822 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6823 include "feature.h".
6824 (scm_socket): return a port, not a file descriptor object.
6825 include "fports.h" and <unistd.h>
6826 (scm_bind): take a port, not a file descriptor object.
6827 take an extra argument for address args.
6829 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6830 INADDR_NONE, INADDR_LOOPBACK.
6832 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6834 * init.c: include net_db.h and not fdsocket.h.
6835 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6837 * Makefile.am: corresponding changes.
6838 * socket.h: renamed from fdsocket.h, fix names.
6839 * net_db.h: renamed from socket.h, fix names.
6840 * socket.c: renamed from fdsocket.c.
6841 remove _sys from procedure names.
6842 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6843 add "socket" to features list.
6844 * net_db.c: renamed from socket.c.
6845 remove _sys from procedure names.
6846 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6847 add "net-db" to features list.
6848 include "net_db.h". don't include <sys/socket.h> or
6851 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6853 * tags.h (scm_tags): Removed comma at end of last enumerator.
6855 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6857 Don't use GCC extensions to allocate space for debugging frames.
6858 (Here he goes again! Why do we put up with this?!)
6859 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6860 an scm_debug_info structure, not an in-line array of them. Add
6861 'info' member, to say how many vect elements we've used, for eval
6863 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6864 a new variable debug_info_end to mark the end of vect, instead of
6865 the address of the 'info' pointer itself.
6866 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6867 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6868 (SCM_APPLY): Explicitly allocate space for debug.vect.
6869 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6870 * stacks.c: Adjusted for new debug frame structure.
6871 (RELOC_INFO, RELOC_FRAME): New macros.
6872 (stack_depth, read_frames): Use them, and new scm_debug_frame
6873 element 'info', instead of magically knowing that eval frames have
6874 an info pointer sitting after vect.
6875 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6877 (scm_init_stacks): Formatting tweaks.
6879 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6881 Give GCC more control flow information, so it can be sure that
6882 variables aren't used uninitialized.
6883 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6884 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6885 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6886 scm_misc_error): Tell GCC that these functions never return.
6887 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6888 out the field type, call abort if SCM_ASSERT returns, to placate
6890 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6891 scm_wta ever returns. We can't handle this case anyway, and this
6892 gives the optimizer more information.
6893 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6894 scm_wta ever returns.
6896 In some cases, the code is fine, but GCC isn't smart enough to
6897 figure that out; this usually happens when one variable is only
6898 initialized and used when a particular condition holds true, and
6899 we know that condition will never change within a given invocation
6900 of the function. In this case, we simply initialize the variables
6901 to placate the compiler, hopefully to a value which will cause a
6902 crash if it is ever actually used.
6903 * print.c (scm_iprin1): Initialize mw_pos.
6904 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6905 * throw.c (scm_ithrow): Initialize dynpair.
6906 * unif.c (scm_uniform_vector_ref): Initialize cra.
6907 * struct.c (init_struct): Initialize prot.
6908 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6910 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6911 if EXPR contains no expressions.
6913 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6915 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6916 cause an infinite loop (???). So much for the algebraic
6917 equivalency of variable-sized arrays and alloca...
6919 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6921 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6922 a SCM boolean, not a C boolean.
6924 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6926 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6927 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6928 rules for raising scm_mtrigger. Previously, unfortunate but not
6929 unlikely circumstances could result in almost constant invokation
6930 of the gc. Now, this situations should be less likely, but they
6931 are not prevented completely.
6933 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6935 * numbers.c (scm_fuck): Procedure removed; looks like old test
6937 * numbers.h: Prototype removed.
6939 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6941 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6942 array to a pointer, to match my Nov 21 change in eval.c.
6944 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6946 * libguile.h: Added #include "libguile/backtrace.h", #include
6947 "libguile/stacks.h".
6949 * strings.c (scm_string scm_make_string scm_string_ref
6950 scm_string_set_x scm_string_equal_p scm_string_append):
6951 Bugfix according to scm patch from Aubrey Jaffer:
6952 Corrected long-standing
6953 (not (eqv? (integer->char 128)
6954 (string-ref (make-string 1 (integer->char 128)) 0)))
6955 bug found by John Kozak <jk@noontide.demon.co.uk>.
6957 * strports.c, strports.h: Make scm_eval_0str return the value of
6958 the last expression evaluated (previously, it returned void).
6960 * strports.c, strports.h: New function: scm_read_0str. Does what
6963 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6965 * simpos.c (scm_getenv): return #f if string can't be found in the
6966 environment instead of throwing an exception, for compatibility
6967 with numerous other systems.
6969 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6971 * Makefile.am (.c.x): Use guile-snarf.
6972 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6974 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6976 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6978 * backtrace.c (scm_display_error_message): Made non-static, and
6979 renamed from display_error_message.
6980 * backtrace.h (scm_display_error_message): Added extern decl.
6981 * throw.c (uncaught_throw): Use it to display the error message.
6983 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6985 * inet_aton.c: Use #if 0, not #ifdef 0.
6987 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6989 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6990 to convert the returned value.
6991 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6992 the offset argument.
6994 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6996 Add new interface to catch/throw, usable from C as well as
6998 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6999 (scm_internal_catch): New function, replaces...
7000 (scm_catch_apply): Deleted.
7001 * throw.c (scm_catch_apply): Deleted; replaced with a more general
7002 mechanism which is a bit more code, but can be used nicely from C
7003 and implement the Scheme semantics as well.
7004 (scm_internal_catch): This is the replacement; it's named after
7005 the analogous function in Emacs.
7006 (scm_catch): Reimplemented in terms of the above.
7007 (struct catch_body_data, catch_body, catch_handler): New
7008 functions, used by scm_catch.
7009 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
7010 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
7011 support for new cwdr.
7013 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
7016 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
7018 * acconfig.h: Added DYNAMIC_LINKING symbol.
7019 * configure.in: Add option and checks for dynamic linking.
7020 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
7021 dynl.h: New files for dynamic linking support.
7022 * Makefile.am (libguile_a_SOURCES):
7024 (modinclude_HEADERS): Added "dynl.h".
7025 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
7027 * init.c (scm_boot_guile_1): Call
7028 scm_init_dynamic_linking to initialize dynamic linking support.
7030 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
7032 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
7033 (as we Schemers say). It needs to be global, so that I can tweak
7034 it for the proper operation of unexec.
7035 (scm_boot_guile_1_live): New variable, see above.
7037 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
7039 * guile-snarf.sh: Removed.
7040 * PLUGIN/guile.libs: Added dependency for -lm.
7041 * acinclude.m4: Renamed from aclocal.m4.
7042 * PLUGIN/greet: Removed.
7043 * Makefile.am, aclocal.m4: New files.
7044 * configure.in: Updated for Automake.
7046 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
7048 * eval.c (scm_definedp): Use top_level_lookup_closure_var
7049 and not top_level_lookup_thunk_var.
7051 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
7053 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
7055 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
7057 * eval.c (scm_definedp): Incompatibly changed to be a builtin
7058 Scheme function, instead of syntax. Single argument is now a
7061 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7063 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
7064 scm_ra_divide): Properly terminate statements passed as arguments
7065 to IVDEP macros. (Thanks to Bernard Urban.)
7067 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
7068 with non-constant sizes. (Thanks to Bernard Urban.)
7070 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7072 It's an "eval closure", not an "eval thunk." A thunk is a
7073 function of no arguments.
7074 * root.h (struct scm_root_state): Renamed
7075 top_level_lookup_closure_var from top_level_lookup_thunk_var.
7076 (scm_top_level_lookup_closure_var): Renamed from
7077 scm_top_level_lookup_thunk_var.
7078 * root.c (mark_root): Uses changed.
7079 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
7080 * init.c (scm_start_stack): Uses changed.
7081 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
7082 Change scheme-visible name to *top-level-lookup-closure* from
7083 *top-level-lookup-thunk*.
7085 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
7087 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
7088 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
7090 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
7092 * gc.c (struct scm_heap_seg_data): Doc fixes.
7094 * gc.c (scm_gc_sweep): Empty all segments' freelists before
7095 sweeping. Then, prepend each segment's free cells to its
7096 freelist, rather than wiping out the old value. (Thanks to Marius
7099 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
7100 scm_check_freelist, scm_debug_newcell): New functions and
7101 variables, for debugging freelist problems.
7102 * pairs.h (SCM_NEWCELL): New debugging version added.
7103 * gc.h (scm_debug_newcell): Added extern declaration, used by
7104 debugging version of SCM_NEWCELL.
7106 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7108 On some systems <libc.h> conflicts with <unistd.h>, and should not
7109 be #included at all.
7110 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
7111 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
7112 * configure.in: Call it.
7113 * posix.c, filesys.c: Use its results to decide whether or not to
7115 * configure, scmconfig.h.in: Rebuilt with autoconf and
7118 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7120 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
7121 pointer to the stdio stream before calling scm_setbuf0, so the
7122 latter will be able to retrieve it. I'm surprised this didn't
7123 segfault earlier. (Thanks to Christopher Lee.)
7125 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7127 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
7130 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7132 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
7133 number of stack narrowing specifier pairs. The first specifier in
7134 a pair controls inner border, the second the outer border. A
7135 number means cut that number of frames, a procedure object means
7136 cut until that object is found in operator position in a frame.
7138 * root.c (cwdr): Bugfix.
7140 * read.c: Recording of positions disabled by default.
7142 * procs.c (scm_closure_p): New function.
7144 * posix.c (scm_tmpnam): New function.
7146 * load.c: Added #include "throw.h".
7147 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
7150 * load.c, load.h (scm_read_and_eval_x): New function.
7152 * eval.c: Renamed debug option "deval" to "debug".
7154 (scm_eval_x): `eval!' is no longer accessible from the scheme
7155 level. Motivation: We can't allow operations which introduce
7156 glocs into the scheme level. Guile's type system can't handle
7157 these as data. Use `eval' or `read-and-eval!' as replacement.
7159 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
7160 SCM_CONSP since this is a macro!; Set vframe.prev to
7161 scm_last_debug_frame instead of 0. In this way we can look
7162 "above" the virtual start stack frame if we wish.
7163 (scm_debug_hang): New function: Useful for debugging Guile in
7164 certain tricky situations. Will probably be removed later...
7166 * debug.h: Changed semantics of debug option "backtrace". This
7167 option now only indicates whether we want automatic backtrace at
7170 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7172 * ports.c: #include "filesys.h"
7173 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
7175 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
7176 Motivation: This is system specific code which is related to file
7177 I/O. It also may use select. Added code by Gary Houston to
7178 detect presence of character in stdio buffers.
7180 * libguile.h: #include "libguile/libpath.h"
7182 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
7183 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
7184 SCM_SITE_DIR; Install libpath.h among the other include files.
7186 * load.c, load.h (scm_sys_package_data_dir): New function.
7188 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7190 * stacks.h: Bugfix: Don't use tail-array length field as stack
7191 length field! This screwed GC.
7193 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7195 * _scm.h: Added #ifndef around definition of macros min and max.
7197 * __scm.h: Added hooks for threads to plugin to in ints protection
7198 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
7199 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
7200 the main code in these macros duplicated and spread over multiple
7201 files. Renamed SCM_THREADS_SWITCHING_CODE ->
7202 SCM_THREAD_SWITCHING_CODE.
7204 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
7206 * snarf.h: New file.
7207 * guile-snarf.sh: New file.
7208 * Makefile.in (inner_h_files): Added snarf.h
7209 (ancillary, install, uninstall, distclean): Added actions for
7211 (.c.x): Use guile-snarf.
7212 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
7213 (gen_c_files): Note that these depend on guile-snarf.
7214 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
7215 now in "snarf.h". Added #include "snarf.h" to get them.
7216 * libguile.h: Added #include "snarf.h".
7217 (Patches applied and tweaked by Jim Blandy.)
7219 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7221 * socket.c: Use K&R style declaration for 'close'; the GNU coding
7222 standards suggest against providing prototypes for system
7223 functions. Thanks to Greg Troxel.
7225 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
7227 * strports.c (scm_eval_0str): New function.
7228 #include "read.h", to get prototype for scm_read.
7229 * Makefile.in (strports.o): Update dependencies.
7230 * strports.h: New prototype.
7232 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
7233 scheme name from "int?" to "integer?". It seems to do the job.
7234 * numbers.h: Rename prototype too.
7235 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
7238 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
7239 scm_num_eq_p): Rename these according to R4RS conventions: call
7240 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
7241 to making libguile R4RS compliant without ice-9...
7243 * load.c (scm_sys_search_load_path): Search for files under all
7244 extensions listed in the %load-extensions variable. If FILENAME
7245 is absolute, return it unchanged, without searching the load path.
7246 (scm_loc_load_extensions): New variable, pointing to
7247 %load-extensions' value cell.
7248 (scm_init_load): Initialize it, and the value it points to.
7249 (scm_primitive_load_path): Improve error reporting.
7251 * load.c (scm_loc_load_hook): New variable, pointing to value cell
7252 of new Scheme variable %load-hook.
7253 (scm_primitive_load): Apply %load-hook to filename.
7255 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
7257 * configure.in: add tests for figuring out whether buffered data
7258 is available in a FILE structure, which is needed by char-ready.
7260 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
7263 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
7264 exceptions using misc_error instead of syserror. It seems a bit
7265 odd to throw an exception if a string can't be found in the
7266 environment, but it's consistent with open-file, stat etc.
7267 (simpos.h): remove sys_ from getenv.
7269 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
7270 occurs, throw an error instead of returning errno. Return value
7272 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
7274 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
7276 * filesys.c (scm_stat2scm): derive file type and permissions from
7277 the stat mode and append them to the returned vector.
7278 There isn't much overhead in doing this and it avoids the need to
7279 work with S_IRUSR et al. in Scheme.
7280 Define symbols scm_sym_regular etc.
7281 (scm_init_filesys): don't intern S_IRUSR etc.
7283 * load.c: change s_try_load and s_try_load_path to s_primitive_load
7284 and s_primitive_load_path.
7286 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
7288 * error.h: don't declare error symbols. prototype for scm_misc_error.
7290 * stackchk.c (scm_stack_overflow_key): defined here instead of in
7293 * error.c: use SCM_SYMBOL to set up error keys.
7294 scm_misc_error: new procedure.
7296 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7298 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
7299 between `#!' and `!#' is ignored.
7300 (skip_scsh_block_comment): New function.
7302 * feature.c (scm_set_program_arguments): New argument, FIRST.
7303 * feature.h: Update prototype.
7304 * init.c (scm_boot_guile_1): Pass new argument to
7305 scm_set_program_arguments.
7307 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7309 * init.c (scm_start_stack): Don't initialize scm_progargs here.
7310 (scm_boot_guile): Call scm_set_program_arguments here, later than
7311 the old initialization.
7313 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
7314 initialization procedure.
7315 - Delete in, out, err arguments; there are other perfectly good
7316 ways to override these when desired.
7317 - Delete result argument; this function shouldn't ever return.
7318 - Rename init_func argument to main_func, for less confusion.
7319 - Delete boot_cmd argument; main_func is more general.
7320 -Add 'closure' argument, to help people pass data to main_func
7321 without resorting to global variables.
7322 - Abort if reentered; don't bother returning an error code.
7323 - Call scm_init_standard_ports to set up the default/current
7324 standard ports; no need to pass them to scm_start_stack.
7325 - Remove code to evaluate the boot_cmd, and start the repl; let
7326 the user do something like that in main_func if they want.
7327 - Remove code to package up a return value; main_func can do any
7329 - Call exit (0), instead of returning.
7330 (scm_start_stack): Don't initialize the I/O ports here; that's
7331 weird. Delete in, out, err arguments. Move guts to
7332 scm_init_standard_ports, scm_stdio_to_port.
7333 (scm_init_standard_ports): New function, to set up current and
7334 default standard ports.
7335 (scm_start_stack, scm_restart_stack): Make these static.
7336 * init.h (scm_boot_guile): Adjust declaration.
7337 (scm_start_stack, scm_restart_stack): Remove externally
7338 visible declarations for these.
7339 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
7341 * fports.c (scm_stdio_to_port): New function. Its guts used to be
7342 written out several times in scm_start_stack.
7343 * fports.h: New declaration for the above.
7345 * feature.c (scm_set_program_arguments): New function.
7346 * feature.h: New declaration for the above.
7348 * ports.c: Formatting tweak.
7350 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
7352 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
7353 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
7354 for obtaining the address of a car or cdr field. Motivation:
7355 &SCM_CXR make assumptions about the internal structure of the
7358 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
7359 Motivation: see SCM_CXRLOC.
7361 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
7362 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
7363 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
7364 Motivation: Safer use. Some other macros are defined in terms of
7365 these operations. If these are defined using the SCM_SETCXR
7366 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
7367 to inefficiency and an <e1> with side-effects could potentially
7368 break. Also, these particular operations are heavily utilized in
7369 the garbage collector. In unoptimized code there will be a
7372 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
7373 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
7374 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
7375 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
7376 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
7377 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
7378 vports.c: Cleaned up use of pairs: Don't make any special
7379 assumptions about the internal structure of selectors and
7380 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
7381 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
7382 (Among other things, this change makes it easier to build Guile
7383 with certain compilers which have problems with casted lvalues.)
7385 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7387 * stacks.c: Improve selection of relevant stack frames when making
7388 a stack object. Introduce one level of indirection in the stack
7389 object to make it possible to "narrow" to a certain region of the
7390 stack. This facilitates making use of more clever algorithms (not
7391 implemented) for selecting relevant frames and gives a cleaner
7392 design since selection of frames can be done independently of
7393 extraction of frames from the real stack.
7394 (scm_stack_id): Also take #t as argument which means look at
7397 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
7398 Turn n_tail into an integer directly representing current number
7399 of frames in stack. Add field tail.
7401 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
7403 * debug.c (scm_make_memoized): Made it available at scheme level.
7404 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
7405 SCM_NIMP before applying heavier predicates in argument checking.
7406 (scm_local_eval): Also take memoized object as argument.
7408 * backtrace.c (scm_display_error): Just a safety measure: Stacks
7409 aren't created with zero length, but should such a strange
7410 creature suddenly turn up...
7412 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
7414 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
7415 `del', for the sake of C++ compilers. (Patch applied by JimB.)
7417 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
7419 * variable.c (scm_make_variable): Make the name hint optional, as
7421 (anonymous_variable_sym): Renamed from variable_sym. All uses
7424 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7425 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7426 of scm_primitive_load_path was also changed to
7427 "primitive-load-path", from "%try-load-path". Callers changed.
7428 We'd like to respect the convention that a function named
7429 "try-mumble" should behave just like the function called "mumble",
7430 but return #f instead of signalling some error.
7431 * load.h: Rename prototypes.
7433 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7435 * print.c (make_print_state, grow_print_state), print.h: Modified
7436 the print state representation: Don't use a tail array for
7437 recording of circular references. Resizing of the print state
7438 structure invalidates the print state pointer. To avoid passing
7439 around an indirect print state reference to all printing
7440 functions, we instead let the print state reference a resizable
7443 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7445 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7446 Don't crash when passed an improper list terminated by a
7447 non-immediate value.
7449 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7451 Allocate data for structures on an eight-byte boundary, as
7452 required by the tagging system.
7453 * struct.c (alloc_struct): New function.
7454 (scm_make_struct, scm_make_vtable_vtable): Call it.
7455 * struct.h (scm_struct_n_extra_words): Bump to 3.
7456 (scm_struct_i_ptr): New "field".
7457 * gc.c (scm_gc_sweep): When we need to free the data, use the
7458 information stored by alloc_struct to find the beginning of the
7459 block allocated to the structure, so we can free it.
7461 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7463 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7466 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7467 (scm_debug_info): New member: id.
7469 * stacks.c: Stacks are now represented as structs; Stacks have an
7470 id given to them by `start-stack'.
7471 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7473 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7474 Changed stack representation.
7476 * debug.c (scm_procedure_name): Try procedure property `name' for
7477 compiled closures aswell.
7479 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7481 * eval.c: scm_i_name moved to gsubr.c
7482 (scm_m_define): Record names of all kinds of procedure
7483 objects. (Earlier, only closures were recorded.)
7485 * procprop.h: Added declaration of scm_i_name.
7487 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7488 (scm_make_gsubr): Record names of compiled closures.
7490 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7492 * debug.c, debug.h: Removed obsolete code.
7494 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7495 stacks.c: Renamed regs --> scm_contregs.
7497 * print.c (scm_free_print_state): Cleanup print state before
7498 returning it to pool. It is better to do it here than in
7499 scm_prin1 since scm_prin1 is called often.
7501 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7502 s_set_source_property_x): Check that first argument is a pair or a
7505 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7506 scm_i_line, scm_i_column and scm_i_breakpoint global.
7508 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7509 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7512 * debug.h: Added debug object smob declaration and macro
7515 * configure.in: Build with backtrace.o and stacks.o if debug
7518 * Makefile.in: Added entries for new files: backtrace.c,
7519 backtrace.h, stacks.c and stacks.h.
7521 * symbols.c (scm_sym2ovcell): Fixed documentation.
7523 * _scm.h (min, max): Added.
7525 * async.c: Moved `min' macro to _scm.h.
7527 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7528 SCM_BACKTRACE_INDENT.
7530 * eval.c: Added new debug options `maxdepth' and `indent'.
7532 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7534 * print.h: Added selector SCM_PRINT_STATE.
7536 * print.c: New functions: scm_make_print_state,
7537 scm_free_print_state.
7539 * print.h: Added declarations for scm_make_print_state,
7540 scm_free_print_state.
7542 * debug.c (scm_m_start_stack): New acro.
7544 * debug.h: Small cleanup.
7546 * init.c (scm_boot_guile_1): Moved scm_init_debug below

7569 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
7570 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
7571 declare functions with prototypes. (Patch thanks to Marius
7574 More prototype-related changes from Marius Vollmer:
7575 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7576 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7577 * ports.h (ptobfuns): Added prototypes. This means some casting in
7579 * fports.c: Added casts for initializations, since the functions
7580 are defined to take FILE * as their stream argument, not SCM.
7581 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7582 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7583 to `char *str_data' to conform to prototype.
7585 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7587 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7589 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7591 * stime.c, stime.h: use SCM_P method.
7593 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7595 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7596 be given at least two arguments. Insist that lst's last element
7597 be a list, but don't make any requirements of its predecessors.
7599 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7601 * eval.c (scm_nconc2last): Revert last change; there seems to be
7602 other stuff going on here.
7604 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7606 * eval.c (scm_nconc2last): Make sure that each element of lst
7607 (which is a list of argument lists, except for the tail) is a
7608 proper list, i.e., finite and terminated by '().
7610 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7612 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7615 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7616 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7619 * vectors.c (scm_make_vector): Fill vectors with the undefined
7620 value, to help make Guile Scheme code more portable to other
7623 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7624 * symbols.h, tags.h: Doc fixes.
7626 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7628 * async.c (scm_take_signal): Doc fixes.
7630 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7632 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7633 want to subtract it from the modulus; we just want to leave it
7636 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7638 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7641 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7643 * throw.c (scm_catch_apply): Finished implementation of
7646 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7648 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7650 (scm_init_filesys): set "i/o-extensions" feature.
7653 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7655 * Makefile.in (root.o): Correct dependencies.
7657 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7659 * Makefile.in: Added dependency entry for root.o.
7661 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7662 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7664 * init.c (scm_start_stack): Set initial root continuation number
7667 * procs.c: New function: scm_thunk_p.
7669 * procs.h: Added declarations of scm_thunk_p.
7671 * root.c: Renamed `call-with-new-root' -->
7672 `call-with-dynamic-root'.
7673 (cwdr): Removed allocation of new root state. This should be done
7674 separately by use of scm_make_root.
7675 (scm_apply_with_dynamic_root): New function: Does what it
7676 sounds like. Needed when spawning threads.
7678 * root.h: Added member last_debug_frame to root state.
7679 Added #include "libguile/debug.h"
7681 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7682 arguments. The motivation is that code in root.c needs catch
7683 functionality, and we want to avoid code duplication.
7684 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7685 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7686 handlers that run without popping the stack into the dynwind
7689 * throw.h: Added prototypes for scm_catch_apply and
7692 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7694 * root.h (scm_root, scm_set_root): Decouple thread support details
7695 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7696 SCM_SET_THREAD_LOCAL_DATA.
7698 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7699 and tortoise scanning loop.
7701 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7703 * Makefile.in: Rebuild dependencies.
7705 * libguile.h: #include "libguile/print.h" before "smob.h", since
7706 the latter uses the print_state structure.
7708 * throw.c (scm_ithrow): Use the correct variable when checking to
7709 see if a given element of scm_dynwinds is a valid catch.
7711 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7712 structure, abort; don't just silently ignore the garbage.
7714 * _scm.h: #include "print.h" here, since it seems to be used just
7716 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7717 strports.c, unif.h: Don't #include "print.h".
7719 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7721 * feature.h (scm_loc_features): Removed external declaration.
7722 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7724 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7726 * feature.c (scm_init_feature): Added threads feature (needs to be
7727 initialized here, since features doesn't exist when
7728 scm_init_threads is called).
7730 * libguile.h: Added #include "libguile/../threads/threads.h".
7731 (This is a kludge to get thread support working. This should be
7734 * configure.in, acconfig.h: Added flags for thread support.
7736 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7739 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7740 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7743 * _scm.h: Added conditional #include "threads.h"
7745 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7746 SCM_THREADS_SWITCHING_CODE.
7748 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7749 allocate the basic dynamic root object.
7750 (scm_boot_guile): Added call to scm_init_root.
7752 * root.c, root.h: Added root smob.
7753 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7754 functions: Implements dynamic roots mostly according to spec in
7755 SCM manual. Main difference is that the second argument is a
7756 throw handler rather than an error "thunk".
7758 * root.h: Added declaration of scm_init_root.
7760 * root.c: Added #include "genio.h", #include "smob.h", #include
7761 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7763 (scm_init_root): Added #include "root.x".
7765 * throw.c: Added #include "stackchk.h"
7766 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7767 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7768 can be used in scm_call_with_new_root; Added reenabling of stack
7769 checking when catching a throw.
7771 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7773 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7775 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7776 element is not found, as per R4RS.
7778 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7780 * list.c: Doc fixes throughout.
7782 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7784 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7785 declare the char * to be const. Avoids a warning in rgx.c.
7787 * ports.h: spelling fix.
7789 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7792 * load.c (scm_sys_try_load_path): throw an error if file not found
7793 (like it says it in NEWS).
7795 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7797 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7798 PROPS slot to '(), not #f; it's an empty alist.
7800 * throw.h, throw.c: Use SCM_P instead of #if hair.
7802 Remove special support for uncaught throws; see throw.c for
7804 * throw.c (uncaught_throw): New function.
7805 (scm_ithrow): Call uncaught_throw if we don't find a throw
7806 target; don't mess with scm_bad_throw_vcell.
7807 (scm_bad_throw_vcell): Variable deleted.
7808 (scm_init_throw): Don't initialize it.
7810 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7813 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7815 * numbers.c (scm_istr2int): If the number is short (as most
7816 numbers are), just call scm_small_istr2int to deal with it.
7817 (scm_small_istr2int): New function, created by un-#ifdefing the
7818 non-bignum version of scm_istr2int and renaming it.
7820 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7822 * load.c (scm_sys_try_load): don't check whether value returned
7823 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7824 Change the Scheme name from %try-load to primitive-load.
7826 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7827 Can avoid passing a message, allowing it to be derived in the
7828 error handler (e.g., if we want to throw to the key both from
7831 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7833 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7834 references now have a new appearance which is more compact and
7835 also gives a clue about what the target of the reference is.
7836 By setting parameters in the print state, more fancy printing can
7837 be achieved. This is used by the (not yet commited) backtrace
7840 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7842 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7845 * print.c: Added #include "struct.h". Removed function
7848 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7849 scm_iprin1. Removed prototype for scm_prlist.
7851 * arbiters.c (prinarb),
7852 async.c (print_async),
7853 debug.c (prindebugobj, prinmemoized),
7854 eval.c (prinprom, prinmacro),
7855 filesys.c (scm_fd_print, scm_dir_print),
7857 mallocs.c (prinmalloc),
7858 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7859 smob.h (scm_smobfuns),
7860 srcprop.c (prinsrcprops),
7862 unif.c, unif.h (scm_raprin1, rapr1),
7863 variable.c (prin_var): Changed argument `int writing' to
7864 `scm_print_state *pstate'.
7866 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7867 that it will be called before scm_init_print.
7869 * print.c (scm_prin1): Print states are now allocated when calling
7870 scm_prin1 and then passed around to all printing functions as an
7871 argument. A cache `print_state_pool' enables reuse of print
7873 (scm_make_print_state): New function.
7874 (scm_iprin1): Adaption to print states.
7875 (scm_iprlist): An initial "hare and tortoise" scan brings down
7876 time complexity to O (depth * N). (Better time complexity will be
7877 achieved when the printing code is completely rewritten.)
7879 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7881 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7882 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7883 it gets done whether or not the cache variable has a value.
7885 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7887 Distinguish #f and ().
7888 * __scm.h: #undef SICP.
7889 * pairs.h (SCM_EOL): Delete this definition, equating it with
7891 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7892 the value it used to have. Doc fixes, too.
7894 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7896 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7897 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7898 Lord's implementation of structs, allowing for tail arrays as
7899 described in the manual. Also fixed some bugs. (Both the interface
7900 and the implementation should be improved.)
7902 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7904 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7905 People who whish to see the source can do `(print-enable 'source)'.
7906 Removed #ifdef DEBUG_EXTENSIONS.
7908 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7910 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7911 integer (assuming for now accepting an integer is a good thing).
7913 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7914 %S will be used instead for write'ing arguments.
7916 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7917 asserts. fix a few other asserts.
7918 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7919 scm_uniform_vector_ref, scm_array_set_x,
7920 scm_dimensions_to_unform_array): change args in
7921 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7922 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7923 scm_substring_fill_x): likewise.
7924 gsubr.c (scm_gsubr_apply): likewise.
7925 eval.c (SCM_APPLY): likewise.
7927 * eval.c (4 places): replace scm_everr with lgh_error or
7930 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7931 scm_memory_error): new procedures.
7932 scm_everr: deleted. can use scm_wta, dropping first two args.
7933 scm_error: convert NULL subr to SCM_BOOL_F.
7935 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7938 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7941 * error.c, error.h: new error keys: scm_arg_type_key,
7942 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7944 scm_wta: reimplement using lgh_error instead of scm_everr.
7946 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7948 * gdbint.c: scm_lread now has one more argument.
7950 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7951 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7952 loading source from non-file ports, which, e. g., happens when
7953 using the Emacs interface).
7955 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7958 * read.c: Added code for recording of positions of source code
7959 expressions; New functions: recsexpr, scm_lreadrecparen;
7960 _scm_make_srcprops --> scm_make_srcprops
7961 (scm_flush_ws): Removed updating of positions counters. This work
7962 is already done by scm_gen_getc
7964 * read.h: Added prototype for scm_lreadrecparen
7966 * print.c: Added #include "alist.h"
7968 * eval.c: Added #include "hash.h"
7970 * eq.c: Added #include "ramap.h"
7972 * options.c: Documentation fixes.
7974 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7975 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7976 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7977 --> scm_make_srcprops
7979 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7980 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7981 function calls in the definition of the whash access macros.
7983 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7985 * init.c (scm_boot_guile): Add level of indirection to
7986 scm_boot_guile_1() to ensure that stack base pointer is properly
7987 initialized. There was no guarantee that variable i was the
7988 highest/lowest variable on stack (i.e. the call frame of
7989 scm_boot_guile was not completely protected from gc).
7991 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7993 * ports.h (scm_port_table): put back file_name, it will be used to
7994 support debugging. Undo related changes in fports.c, ioext.c,
7997 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7999 * ports.h (scm_port_table): remove file_name member for now, it seems
8001 * fports.c (scm_open_file): don't set file_name in PTAB.
8002 (prinfport): don't use file_name in PTAB.
8003 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
8004 * ports.c (scm_add_to_port_table): don't intialize file_name.
8005 (scm_port_file_name): remove for now.
8006 * gc.c (scm_gc_mark): don't mark PTAB file_name.
8008 * fports.h (scm_mkfile): prototype deleted.
8009 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
8011 * debug.c, unif.c: use scm_out_of_range instead of
8012 wta for range errors (ASSERT still needs work).
8014 * error.c, error.h (scm_out_of_range): new procedure.
8016 * error.c, error.h (scm_out_of_range_key): new key.
8018 * posix.c (scm_sync): #else was missing.
8020 * error.c, error.h: append _key to names scm_num_overflow and
8023 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
8024 of consing an empty list.
8025 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
8026 of macros, saves code and string space.
8027 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
8028 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
8029 lower case. Rename scm_syserror_m to scm_syserror_msg.
8030 error.h: prototypes for new procedures.
8032 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
8034 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
8036 * error.c, error.h: setup scm_num_overflow key.
8038 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
8039 Remove definition of SCM_OVSCM_FLOW.
8041 * fports.c (scm_open_file): use SCM_SYSERROR_M.
8043 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
8044 explicit message and args.
8046 * error.c, error.h, __scm.h: change system_error_sym to
8049 * error.c (system_error_sym): remove leading %% from the Scheme name
8052 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
8054 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8056 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
8057 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
8058 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
8059 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
8060 renamed. (These were introduced by unsupervised name
8063 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8065 * print.c: Added code for detection of circular references during
8066 printing. (init_ref_stack, grow_ref_stack): New functions. Added
8067 a hook for printing of closures (accessible via print options).
8068 This leads to a split of calls to scm_iprin1 into two classes:
8069 elementary print operations (e. g. the code which prints a smob)
8070 still use scm_iprin1 while top level calls (like scm_display) use
8071 scm_prin1. scm_prin1 begins by clearing the data structure used
8072 to record reference information.
8074 * print.h: Added declarations of scm_prin1 and scm_prlist.
8076 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
8078 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
8080 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
8082 * error.c (err_head): scm_iprin1 --> scm_prin1
8084 * debug.c: Adjusted header comment.
8088 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
8090 * strerror.c: Doc fix.
8092 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8094 * gdbint.c (gdb_read): Now possible to run during GC.
8095 (unmark_port, remark_port): New functions.
8097 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
8099 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
8100 of allocating a new string object. Also, increase size by
8101 the factor 2 instead of 1.5.
8103 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
8105 * __scm.h (SCM_P): Corrected to run under traditional C.
8107 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
8110 * async.c: Calls to scm_sysintern corrected.
8112 * async.h (scm_async_clock): Redundant declaration removed.
8114 * continuations.c (scm_dynthrow): Redundant declaration removed.
8116 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
8117 Definition typos corrected.
8119 * debug.h: Missing declarations of functions in debug.c added
8122 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
8123 Missing declarations to functions in eval.c added.
8125 * filesys.c: Possibly uninitialized variable rv.
8127 * gc.h (scm_object_addr, scm_unhash_name): Missing
8128 declarations of functions defined in gc.c added.
8130 * genio.c: Possible typos str_data -> wstr_data. ???
8132 * genio.c: Possibly unintended shadowing of local variable
8133 `int c' (gotos out of scope of inner `c'). ???
8135 * init.c: Uninitialized `SCM last' may be used.
8137 * ioext.h: (scm_sys_isatty_p): Typo.
8139 * list.h (scm_list_head): Missing prototype for function in
8142 * numbers.c (scm_two_doubles): Changed from extern to static
8143 (is used only within numbers.c).
8145 * numbers.h: Repeated declarations removed.
8147 * ports.h (scm_close_all_ports_except): Declaration for the
8148 function defined in ports.c added.
8150 * posix.h: Missing declarations added.
8152 * procs.h (scm_make_subr_opt): Missing declaration added.
8154 * socket.h (scm_sys_gethost): Missing declaration added.
8156 * socket.h: Redundant declarations removed (they are in fdsocket.h).
8158 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
8159 Missing declarations added.
8161 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
8163 * struct.c: Uninitialized variable `SCM answer' may be used.
8165 * unif.c (l2ra): Declaration prototype.
8167 * unif.c (scm_array_equal_p): Dummy definition removed (it is
8168 defined in ramap.c).
8170 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
8171 Redundant declarations removed (they are in ramap.h).
8173 * variable.h (scm_make_udvariable,
8174 scm_make_undefined_variable): Declaration corrected to
8175 correspond variable.c.
8177 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
8178 Missing declarations added.
8180 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
8182 * Makefile.in (distclean): Don't forget to delete fd.h.
8184 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
8186 * fd.h.in, tags.h: Trivial cleanups.
8188 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
8189 marksweep.h just declared functions from gc.c.
8190 * gc.h, libguile.h: Don't #include "marksweep.h".
8191 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8192 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
8193 dependencies updated.
8195 * libguile.h: Don't #include "files.h"; it's been deleted.
8197 * files.c (scm_sys_delete_file): Moved to filesys.c.
8198 File is now empty; deleted.
8200 * filesys.c: scm_sys_delete_file is now here. Remove
8201 #if's; they seem to rely on remnants of an old portability
8202 regimen. If the problems come up again, solve them properly,
8203 using autoconf. Specifically: Don't test M_SYSV, and #define
8204 remove to be unlink if it's #defined; don't use remove just
8205 because HAVE_STDC_HEADERS is #defined.
8206 * filesys.h: Add declarations for scm_sys_delete_file.
8207 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8208 files.o, files.h, files.c, and files.x.
8209 * init.c: Don't #include "files.h", and don't call scm_init_files.
8211 Use SCM_P instead of PROTO; the latter intrudes on the user's
8213 * params.h: Deleted; definition of SCM_P moved to...
8214 * __scm.h: ... here, where it replaces PROTO macro.
8215 * libguile.h, smob.h: Don't #include "params.h".
8216 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
8217 smob.h: Fix prototypes accordingly.
8218 * Makefile.in: Update dependencies.
8219 (inner_h_files): Remove params.h.
8221 * gc.c: #include "gc.h"; every module should include its header,
8222 to let the compiler cross-check the declarations against the
8225 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
8226 simpos.h: #include "libguile/__scm.h".
8228 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
8230 * init.c: Don't forget to #include smob.h and init.h.
8231 * Makefile.in: Dependencies updated.
8233 * smob.h: Use PROTO instead of #if __STDC__.
8235 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
8237 * __scm.h: Doc fixes.
8239 * __scm.h, libguile.h: Use "quotes" in the #includes, not
8240 <angles>; this allows `make depends' to work properly.
8242 * libguile.h: #include smob.h and pairs.h before the others; they
8243 define typedefs used by other headers.
8245 C files should #include only the header files they need, not
8246 libguile.h (which #includes all the header files); the pointless
8247 recompilation was wasting my time.
8248 * Makefile.in (all .o dependency lists): Regenerated.
8249 * libguile.h: Don't try to get a definition for size_t here...
8250 * __scm.h: Do it here.
8251 * _scm.h: Since this is the internal libguile header, put things
8252 here that all (or a majority) of the libguile files will want.
8253 Don't #include <libguile.h> here; that generates dependencies on
8254 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
8255 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
8256 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

8353 * weaks.c: Get "weaks.h".
8355 * stackchk.h: #include "libguile/debug.h",
8357 * print.h, read.h: #include "options.h", since everyone who uses
8358 either of these files will need that.
8360 * smob.h: #include "ports.h", "genio.h", and "print.h", since
8361 anyone who uses this file will need them to define the smob
8362 printing functions. Also, get markers.h, since people will need
8363 to #define the mark functions.
8365 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
8366 * ports.h: ... to here.
8368 * ports.h (scm_port_table_size): Explicitly give type as 'int';
8369 don't rely on archaic C default type rules.
8371 * fports.h: #include "libguile/ports.h", since you need that in
8372 order to parse this.
8374 * genio.h: #include "libguile/print.h", because you need that to
8375 parse this; don't bother #including "ports.h", since print.h gets
8378 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
8380 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
8381 this; it's now a reference to an element of *scm_root.
8383 * debug.h: Don't #include "options.h"; the compiler won't be able
8384 to find that once the headers are installed; instead, #include
8385 "libguile/options.h".
8386 * gc.h: Same, with marksweep.h.
8387 * mbstrings.h: Same, with symbols.h.
8388 * scmhob.h: Same, with _scm.h.
8389 * smob.h: Same, with params.h.
8391 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
8392 C files; there's no need for this, and it forces recompilations
8395 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
8397 * error.c (scm_error): declare scm_error_callback.
8399 * error.h: prototype for scm_error_callback.
8401 * __scm.h: define lgh_error.
8402 (SCM_SYSERROR): redefine using lgh_error.
8404 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
8406 * error.c (scm_error): new procedure.
8408 * error.h: prototype for scm_error.
8410 * Makefile.in (install): install scmconfig.h from the current
8411 directory, not $(srcdir).
8413 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8415 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8416 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8417 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
8418 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,

8423 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8424 vports.h, weaks.h: #include "libguile/__scm.h", not
8425 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
8426 dependencies are within libguile properly.
8428 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8430 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8431 when scmconfig.h doesn't exist.
8433 * load.c (scm_sys_try_load): Correct spelling.
8435 * feature.c (scm_loc_features): Make this static.
8437 * Makefile.in (libpath.h): Omit trailing slash from path. We
8438 shouldn't require it of users, so why put it here?
8440 Move code to initialize and search %load-path from ice-9 to C
8441 code, so we can use the load-path to find the ice-9 boot code;
8442 this makes it easier to run Guile without installing it. See
8443 corresponding changes in guile/Makefile.in.
8444 * feature.c: Move stuff concerned with the load path to load.c.
8445 (scm_compiled_library_path): Deleted.
8446 Don't #include libpath.h here.
8447 * feature.h: Don't mention scm_compiled_library_path.
8448 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8449 <sys/stat.h>, and <unistd.h> (if present).
8450 (R_OK): #define if the system hasn't deigned to.
8451 (scm_loc_load_path): New variable.
8452 (scm_init_load_path, scm_sys_search_load_path,
8453 scm_sys_try_load_path): New functions.
8454 (scm_init_load): Initialize scm_loc_load_path to point to the
8455 value cell of the Scheme %load-path variable.
8456 * load.h: Add declarations for scm_sys_search_load_path,
8457 scm_sys_try_load_path.
8458 * init.c: Call scm_init_load_path.
8459 * Makefile.in (feature.o, load.o): Dependencies updated.
8461 * load.c, load.h: Rewrite using PROTO macro.
8463 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8465 * gc.c (scm_cellp): New function: C predicate to determine if an
8466 SCM value can be regarded as a pointer to a cell on the heap.
8468 * gc.h: Added declaration of scm_cellp.
8470 * gdb_interface.h: New file: The GDB interface header from the GDB
8473 * gdbint.c: New file: GDB interface.
8475 * gdbint.h: New file: GDB interface.
8477 * libguile.h: Added #include <libguile/gdbint.h>.
8479 * init.c (scm_boot_guile): Added scm_init_gdbint.
8481 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8482 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8483 found if object files and source are kept separate).
8485 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8487 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8489 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8491 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8492 TK_SRC_DIR; they're not relevant any more.
8494 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8495 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8497 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8499 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8500 search path, so we can find the <libguile/MUMBLE.h> headers.
8502 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8504 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8505 implicit in the .c.o rule.
8506 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8509 Put the library path in a header file, instead of passing it on
8510 the command line in every compilation.
8511 * Makefile.in (libpath.h): New target.
8512 (feature.o): Depend on libpath.h.
8513 (clean): Delete libpath.h.
8514 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8515 * feature.c: ... #include "libpath.h" here.
8516 * .cvsignore: Ignore libpath.h.
8518 Don't install the unwashed masses of Guile header files in the
8519 main #include path; put most of them in a subdirectory called
8520 'libguile'. This avoids naming conflicts between Guile header
8521 files and system header files (of which there were a few).
8522 * Makefile.in (pkgincludedir): Deleted.
8523 (innerincludedir): New variable; this and $(includedir) are enough.
8524 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8525 (installed_h_files): Divide this up. Now this variable lists
8526 those header files which should go into $(includedir) (i.e. appear
8527 directly in the #include path), and ...
8528 (inner_h_files): ... this new variable says which files appear in
8529 a subdirectory, and are referred to as <libguile/mumble.h>.
8530 (h_files): List them both.
8531 (install): Create innerincludedir, not pkgincludedir. Put
8532 the installed_h_files and inner_h_files in their proper places.
8533 (uninstall): Corresponding changes.
8534 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8535 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8536 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8537 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8538 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8539 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8540 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8541 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8542 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8543 vports.h, weaks.h: Find __scm.h in its new location.
8544 * __scm.h: Find scmconfig.h and tags.h in their new locations
8545 (they're both "inner" files).
8547 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8549 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8551 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8553 * posix.c: Doc fixes.
8555 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8557 * socket.c: Don't include a prototype for inet_aton; just use a
8558 K&R style declaration, to avoid warnings but minimize the chance
8559 of conflicts with the system.
8561 On NextStep, <utime.h> doesn't define struct utime, unless we
8562 #define _POSIX_SOURCE before #including it.
8563 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8564 * acconfig.h: New comment text for above CPP symbol.
8565 * configure.in: Call it.
8566 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8568 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8570 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8571 testing for __EMX__.
8573 * posix.c: #include <libc.h>, if it exists.
8575 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8576 don't even know if the latter exists.
8578 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8579 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8580 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8582 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8584 (scm_init_posix): Use them when initializing the Scheme constants
8587 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8589 * Makefile.in (libdir, includedir, bindir): Use the
8590 autoconf-supplied values, instead of deriving them ourselves.
8591 (pkgincludedir, datadir, pkgdatadir): New variables.
8592 (install, uninstall): Put the header files in a special
8593 subdirectory, not in the main search path.
8595 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8596 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8598 * Makefile.in (IMPLPATH): Deleted; never used.
8600 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8601 on the Tcl/Tk source any more.
8602 (INCLUDE_CFLAGS): Remove references to the above.
8604 * Makefile.in (version.o): Corrected dependencies.
8606 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8608 * libguile.h: #include "version.h"
8610 * init.c (scm_boot_guile): Call scm_init_version.
8611 * gscm.c (gscm_run_scm): Call scm_init_version.
8613 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8614 GUILE_VERSION): AC_DEFINE these.
8615 (acconfig.h): #undef the above symbols.
8617 * Makefile.in (libobjs): Add version.o.
8618 (installed_h_files): Add version.h.
8619 (c_files): Add version.c.
8620 (gen_c_files): Add version.x.
8621 (version.o): New rule.
8622 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8623 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

8632 weaks.o): Add version.h to dependency lists.
8633 (markers.o): Remove duplicate rule.
8635 * version.h: New file.
8637 * version.c: New file.
8639 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8641 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8642 array; use it appropriately. Since GCC is quite happy to
8643 subscript functions, it never warned us about this; we should use
8644 -Wpointer-arith in the future. I guess we never tested
8647 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8649 * socket.c: Doc and copyright fixes.
8651 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>

8655 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8657 * socket.c: Added declaration of inet_aton to avoid compiler
8658 warning. (Hope this solution is correct.)
8660 * stime.c: Added declaration of ftime. (This is missing in
8663 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8665 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8667 * Makefile.in (c_files): add strerror.c.
8669 * strerror.c: new file from Emacs' sysdep.c.
8670 maybe configure should also check for sys_errlist.
8672 * configure.in (AC_REPLACE_FUNCS): add strerror.
8674 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8676 * debug.c (scm_init_debug): Added initialization for
8677 scm_evaluator_traps.
8679 * debug.h, debug.c: Various name changes.
8680 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8681 "debug-options-interface". See commentary in options.c.
8683 * options.h, options.c: Options now have documentation strings.
8684 Also added a long explanatory commentary.
8686 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8689 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8690 last_debug_info_frame is now updated in all cases.
8692 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8695 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8697 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8698 Added option STACK_CHECKING.
8700 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8702 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8704 * __scm.h: Removed symbols for debugging support.
8706 * acconfig.h: Added symbols for debugging support.
8708 * configure.in: Added user option for debugging support.
8709 --enable-debug will include the debugging code into libguile.a.
8711 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8712 scm_relocate_chunk_to_heap.
8714 * debug.c: New file: low-level debugging support. It also
8715 includes support for debugging with gdb. (The extensions to gdb
8716 are written by Per Bothner at Cygnus.)
8718 * debug.h: New file: low-level debugging support.
8720 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8721 argument pairs. Extensive modifications to the debugging
8722 evaluator. Added "SECTION:" commentaries to clarify what happens
8723 when, during double compilation. Renamed EVALIMP --> EVALIM.
8724 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8725 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8726 the beginning of the file. New procedure: scm_unmemocopy.
8727 Added some global state variables needed by the debugging
8728 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8729 check_entry, check_apply, check_exit, debug_options and
8730 evaluator_traps. New acro: undefine.
8732 * eval.h: Renamed EVAL --> XEVAL.
8734 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8735 --> scm_make_weak_key_hash_table.
8737 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8738 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8740 * libguile.h: Conditionally include debug.h
8742 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8743 scm_object_properties shouldn't return handle. `handle' now gets
8744 initialized in scm_set_object_properties_x. scm_object_properties
8745 doesn't any longer create an entry in scm_object_whash.
8747 * options.c: New file: handling of run time options.
8749 * options.h: New file: handling of run time options.
8751 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
8753 * print.c: New procedure: scm_print_options
8755 * print.h: Defines for print options.

8772 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8774 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8776 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8778 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8779 and should be called by the final client.
8781 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8783 * gc.h: Use the PROTO macro when declaring functions.
8784 * gc.c: Use the PROTO macro when declaring static functions.
8785 Remove the CPP hair around function definitions.
8787 * gc.c (scm_init_storage): Initialize scm_asyncs.
8789 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8790 preprocessor symbol; "__scm.h" is where it might get #defined.
8791 * __scm.h: Similar: #include <scmconfig.h> before testing
8794 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8796 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8798 * init.c (scm_boot_guile): Add init_func argument; call
8799 (*init_func) instead of calling scm_appinit; it's ucky to
8800 hard-code names for the user's procedures.
8801 * init.h (scm_boot_guile): Adjust declaration.
8803 * __scm.h (PROTO): New macro, for declaring functions with
8806 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8807 eliminate all the __STDC__ conditionals.
8808 (scm_boot_guile): Add declaration.
8809 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8810 Remove __STDC__ conditionals around function definitions; the
8811 declarations in init.h will provide the same information, more
8814 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8815 complain about it in the error message; the error message is
8816 adequate without that note, and there's nothing the user can do
8819 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8821 * Makefile.in (ancillary): Drop def.sed.
8823 * posix.c (scm_init_posix): Use numeric values, rather than
8824 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8825 F_OK. The symbols aren't available on some systems, and I'm
8826 pretty sure their values are fixed by common widespread practice.
8827 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8829 More functions unavailable on some systems.
8830 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8831 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8833 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8834 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8835 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8836 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8837 stub that signals an error as the #else.
8839 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8841 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8843 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8845 * unif.c: include ramap.h.
8847 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8849 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8851 * ports.c: include sys/ioctl.h.
8853 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8855 * configure.in: check for sys/ioctl.h.
8857 * ports.c: include <malloc.h> not "malloc.h".
8859 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8861 * fports.c: remove ttyname and tmpnam declarations.
8863 * posix.c: fewer ttyname declarations.
8865 * fports.c: include <string.h> not "string.h".
8867 * init.c, ioext.c: include string.h and unistd.h.
8869 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8871 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8872 genio.c, simpos.c, vports.c: include string.h.
8874 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8876 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8878 (scm_addr_buffer_size): change type from scm_sizet to int.
8879 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8880 from scm_sizet to int.
8882 * error.c: include unistd.h.
8884 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8887 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8889 * __scm.hd, def.sed: deleted.
8891 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8893 Changes for NeXT, suggested by Robert Brown.
8894 * configure.in: Call AC_TYPE_MODE_T.
8895 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8896 NeXT. Put header file list in alphabetical order.
8897 * configure, scmconfig.h.in: Regenerated.
8898 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8900 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8903 * acconfig.h: New file, providing documentation for the CPP
8904 symbols defined in configure.in
8905 * acconfig-1.5.h: Removed; superceded by the above.
8907 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8909 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8911 * fports.c (scm_open_file): don't return #f, throw error.
8913 * ioext.c (fileno): renamed from %fileno.
8914 (soft-fileno): deleted.
8916 * ports.c (scm_port_revealed): don't need to check for -1 from
8918 (scm_set_port_revealed_x): return unspecified, not #f.
8920 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8922 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8924 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8926 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8928 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8930 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8931 This is necessary on Ultrix, and doesn't hurt portability.
8933 * Makefile.in (dist-dir): New target, implementing a new dist system.
8934 (installed_h_files): Put in alphabetical order.
8935 Remove duplicate entries for markers.h and unif.h.
8936 (c_files): Remove duplicate entries for markers.c.
8937 (ancillary): Renamed from anillery; all uses changed. Remove
8938 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8939 Remove all the ../doc/* files; doc/Makefile.in handles that.
8941 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8943 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8944 every if must have an else, or else the whole command has a
8945 non-zero exit code whenever the if's condition is false.
8947 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8949 * posix.c: include string.h.
8951 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8953 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8956 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8957 Remove leading % from scheme names.
8958 Do not return error values, call SCM_SYSERROR or similar.
8960 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8962 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8964 * struct.c (scm_init_struct): new file.
8966 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8968 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8969 (scm_list_head): added list-head for rapidly chopping argument
8970 lists off of longer lists (and similar).

8974 * objprop.c (scm_object_property): assq the cdr of the whash
8975 handle for obj, not the handle itself.
8977 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8979 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8980 weak hash tables last of all marking to avoid an obscure gc bug.
8981 WARNING: circular lists stored in a weak hash table will hose us.
8983 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8985 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8986 new functions similar to scm_substring_move_left_x and
8987 scm_substring_move_right_x.
8989 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8991 * init.c (scm_boot_guile): prevent gc with scm_block_gc not

8996 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8998 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
9000 * strports.c (scm_strprint_obj): convenience function. C for
9001 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
9003 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
9004 removed to a separate library
9006 * init.c (scm_boot_guile): copied from guile-tcl.c.
9007 Initialization specific to tcl interpreters removed.
9009 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
9011 * ports.c (scm_ports_prehistory): size malloced here doesn't
9012 matter so long as it is non-0 (got rid of "* 4").
9014 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
9016 * gscm.h: gscm_mkarray eliminated (presumably was not being used
9017 since its definition was bogus).
9019 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
9021 * mallocs.[ch]: back again (for rx at least).
9023 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
9025 * ports.c: removed functions relating to the mapping between ports
9026 and descriptors. (That stuff is unix-specific and should be collected
9027 in a separate library).
9029 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
9030 (Tom Mckay@avanticorp.com)
9032 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
9034 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
9035 handled correctly (SCM_FREEP was applied to them) -- test for
9036 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
9037 being overwritten with #f. (brown@grettir.bibliotech.com)
9039 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
9041 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

9044 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
9046 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak

9051 * list.c (scm_last_pair): map '()=>'()
9053 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>

9056 Generalized assoc and hash-table functions.
9057 Factored pairs.c into multiple files.
9059 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
9061 * gscm.c (gscm_run_scm): got rid of objprop.
9063 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>

9069 NOTE: don't use a alist here.
9070 (scm_set_procedure_properties_x): fix type checking throughout this file.
9072 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.

9080 * vports.c (scm_make_soft_port): allocate a port table entry
9081 (possibly triggering gc) before setting the tag of the corresponding
9084 * pairs.c (scm_delq_x): never throw an error.
9086 * vectors.c (scm_make_vector): made the default vector fill argument
9087 into '() (much more useful than the previous value, "#unspecified")
9089 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
9091 * ports.c (scm_add_to_port_table): Added fields
9092 to port table entries: file_name, line_num, col.
9093 Update these in open_file, gen_getc and gen_ungetc.
9094 Added procedures to access those fields.
9096 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
9098 * procs.c (scm_make_subr_opt): new entry point for making
9101 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
9103 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.

9107 * numbers.c (scm_exact_p): This function no longer
9108 implements "integer?".

9112 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
9113 (scm_gc_stats): return an assoc of useful data. Replaces "room"
9114 and the stats reporting formerlly built into repl.

9117 GC statistics keeping moved to gc.c.
9118 Other statistics keeping can be done from Scheme.
9119 REPLS are now written in Scheme.
9121 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
9123 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky

9126 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
9128 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
9130 * feature.c (scm_compiled_library_path): moved here from repl.c.
9131 This file is for stuff relating specifically to Scheme libraries
9134 * eval.c (scm_m_define): don't give warning about redefinition, don't
9137 NOTE: this should throw a resumable exception with parameters --
9138 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
9140 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
9142 * error.c: scm_warn eliminated.

9154 between the call to procedurep and use.
9156 * error.c (scm_everr):
9158 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
9161 * strports.c: don't reveal the port's string to the caller
9162 because it changes size.
9164 (stputc stwrite): check/change the strings length with interrupts
9167 * objprop.c (scm_set_object_property_x &c): use the generic
9168 hashing functions and be threadsafe.
9170 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
9171 (per suggestion jaffer@gnu.ai.mit.edu).
9173 * mbstrings.c (scm_multi_byte_string): guard against argument list
9176 * strings.c (scm_make_string): loop cleanup
9178 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
9181 * weaks.c (scm_weak_vector): guard against argument list
9184 * variable.c (scm_builtin_variable): check for/make a built-in

9192 functions. hash, hashq, hashv, hashx.
9194 * tags.h: made wvect an option bit of vector.

9198 * symbols.c: made the basic symbol table operations atomic.
9200 * root.c &c.: collected stack-specific global state.

9204 initialization to fix a race condition.
9206 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
9207 object, not in a global.
9208 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
9210 * throw.c (_scm_throw): Pass throwval on the stack, not in a global
9211 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)

9225 * async.c: New support for interrupt handlers.
9227 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
9229 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
9230 set the multi_byte flag correctly in symbols. This is wrong.
9231 intern_obbary_soft and msymbolize should take an extra parameter.
9232 Also, weird multibyte symbols don't print correctly.
9233 The weird symbol syntax is also a bit bogus (emacs doesn't quite
9236 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
9238 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
9239 use the system symhash. == #t means create an uninterned symbol.
9241 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
9243 * strings.c (scm_make_shared_substring): build'em.
9244 It might better to keep a table of these and use one
9245 less cons-pair per shared-substring.
9247 Tue Feb 6 17:45:21 1996 Tom Lord <lord@beehive>
9249 * strings.c (scm_string_shared_substring): create shared

9297 * error.c (def_err_response): (int)scm_err_pos => (long)scm_err_pos
9298 Eliminate a (presumed) warning on some systems.

9306 (kawai@sail.t.u-tokyo.ac.jp)
9308 * gscm.c (gscm_set_procedure_properties_x): parameter "new" => "new_val"
9309 for C++. (Seth Alves <alves@gryphon.com>)
9311 (gscm_cstr): uses an uninitialized local variable causing
9312 segv. (kawai@sail.t.u-tokyo.ac.jp)
9315 * lvectors.c (scm_get_lvector_hook):
9316 In guile-ii, the lvector code was broken. It was fixed in guile-iii.
9317 It seems to me like if it is broken again in guile-iv...Here is a patch.

9322 * gscm.c (gscm_sys_default_verbosity):
9323 incorrectly declared for non-__STDC__
9324 (Tom_Mckay@avanticorp.com)
9326 * ports.c (scm_setfileno): Tweak the macro a bit
9327 to make it easier to port to systems that use
9328 more than a single structure field to hold a descriptor.
9330 * debug.c (change_mode): Avoid GNUCism "int foo[n];"
9331 Give a warning, not an error, for unrecognized modes.

9394 Tue Jan 23 13:29:40 1996 Tom Lord <lord@beehive>
9396 * elisp.c (new file): dynamic scoping and other bits for

9398 hack on elisp emulation.
9400 * dynwind.c (scm_dowinds): When entering or leaving a dynamic

9410 * eval.c (SCM_CEVAL): if the function position evaluates
9411 to a macro, process it accordingly. (Previously, macros were
