1 1999-11-22 Jim Blandy <jimb@savonarola.red-bean.com>
3 * gscm.c, gscm.h: Deleted. They were unused.
5 1999-11-20 Gary Houston <ghouston@freewire.co.uk>
7 * unif.c (scm_list_to_uniform_array): call
8 scm_dimensions_to_uniform_array with a third argument of
9 SCM_UNDEFINED instead of SCM_EOL.
11 1999-11-19 Gary Houston <ghouston@freewire.co.uk>
13 * the following changes allow guile to be built with the array
14 "module" omitted. some of this stuff is just tc7 type support,
15 which wouldn't be needed if uniform array types were converted
18 * tag.c (scm_utag_bvect ... scm_utag_cvect): don't define unless
20 (scm_tag): don't check array types unless HAVE_ARRAYS.
22 * sort.c (scm_restricted_vector_sort_x, scm_sorted_p):
23 remove the unused array types.
24 * (scm_stable_sort, scm_sort): don't support vectors if not
25 HAVE_ARRAYS. a bit excessive.
27 * random.c (vector_scale, vector_sum_squares,
28 scm_random_solid_sphere_x, scm_random_hollow_sphere_x,
29 scm_random_normal_vector_x): don't define unless HAVE_ARRAYS.
31 * gh_data.c (makvect, gh_chars2byvect, gh_shorts2svect,
32 gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect, gh_doubles2dvect,
33 gh_uniform_vector_length, gh_uniform_vector_ref):
34 don't define unless HAVE_ARRAYS.
35 (gh_scm2chars, gh_scm2shorts, gh_scm2longs, gh_scm2floats,
37 don't check vector types if not HAVE_ARRAYS.
39 * eq.c (scm_equal_p), eval.c (SCM_CEVAL), print.c (scm_iprin1),
40 gc.c (scm_gc_mark, scm_gc_sweep), objects.c (scm_class_of):
41 don't support the array types unless HAVE_ARRAYS is defined.
43 * tags.h: make nine tc7 types conditional on HAVE_ARRAYS.
45 * read.c (scm_lreadr): don't check for #* unless HAVE_ARRAYS is
46 defined (this should use read-hash-extend).
48 * ramap.c, unif.c: don't check whether ARRAYS is defined.
50 * vectors.c (scm_vector_set_length_x): moved here from unif.c. call
51 scm_uniform_element_size if HAVE_ARRAYS.
52 vectors.h: prototype too.
54 * unif.c (scm_uniform_element_size): new procedure.
56 * init.c (scm_boot_guile_1): don't call scm_init_ramap or
57 scm_init_unif unless HAVE_ARRAYS is defined.
59 * __scm.h: don't define ARRAYS.
61 * Makefile.am (EXTRA_libguile_la_SOURCES): unif.c and ramap.c
62 moved here from libguile_la_SOURCES.
64 1999-11-18 Gary Houston <ghouston@freewire.co.uk>
66 * socket.c (scm_htons, scm_ntohs, scm_htonl, scm_ntohl): new
67 functions for network data conversion.
69 * numbers.c (scm_num2long, scm_num2longlong):
70 throw out-of-range instead of wrong-type-arg if appropriate.
71 (scm_iint2str): handle -2^31 correctly.
72 (scm_num2long): handle -2^31 bignum correctly.
73 (scm_num2long_long): rewrite the bigdig case: basically copied
75 numbers.h: (SCM_BITSPERLONGLONG): deleted.
77 * unif.c (rapr1): use sprintf instead of intprint for unsigned
78 longs: intprint can't cope with large values.
80 * numbers.c (scm_num2ulong): check more consistently that the
81 input is not negative. if it is, throw out-of-range instead of
84 * ramap.c (scm_array_fill_int): don't limit fill to INUM for
85 uvect, ivect or llvect.
86 Check that fill doesn't overflow short uniform array.
88 * __scm.h: add another long to the definition of long_long and
91 * unif.c (scm_raprin1): use 'l' instead of "long_long" in the
92 print representation of llvect. read can't handle more than
94 (scm_dimensions_to_uniform_array): make "fill" an optional argument
95 instead of a rest argument.
97 * tags.h (scm_tc7_llvect): wasn't defined anywhere, so use the free
100 * __scm.h: don't mention LONGLONGS.
102 * unif.c, numbers.c, eq.c, gc.c, print.c, eval.c, ramap.c:
103 replace LONGLONGS with HAVE_LONG_LONGS as set by configure.
105 1999-11-17 Gary Houston <ghouston@freewire.co.uk>
107 * net_db.c (scm_inet_aton): throw errors using the misc-error key
108 instead of system-error. inet_aton doesn't set errno.
109 system-error isn't right in gethost either, since it's throwing
110 the value of h_errno instead of errno. so:
111 (scm_host_not_found_key, scm_try_again_key,
112 scm_no_recovery_key, scm_no_data_key): new error keys.
113 (scm_resolv_error): new procedure, use the new keys.
114 (scm_gethost): call scm_resolv_error not scm_syserror_msg.
116 1999-11-16 Gary Houston <ghouston@freewire.co.uk>
118 * error.c: (various): use scm_cons instead of scm_listify
119 to build short lists.
121 1999-11-03 Gary Houston <ghouston@freewire.co.uk>
123 * socket.c (scm_fill_sockaddr): zero the address structure before
124 use, in case it has a sin_len field and the OS doesn't like random
125 values (thanks to Bertrand Petit).
127 1999-10-26 Mark Galassi <rosalia@lanl.gov>
129 * gh.h, gh_data.c (gh_symbol2scm): changed gh_symbol2scm() to take
130 a const char * argument, upon suggestion from Lynn Winebarger.
132 1999-10-26 Gary Houston <ghouston@freewire.co.uk>
134 * strports.c (st_end_input): avoid dubious pointer arithmetic.
136 1999-10-24 Gary Houston <ghouston@freewire.co.uk>
138 * Move the responsibility for resetting port buffers from the
139 caller of the ptob seek procedure to the implementation. This
140 gives more control in general to the ptob seek: in particular the
141 change of 1999-10-20 can be made to work without breaking seek on
142 string ports. There's a comment in NEWS about upgrading port
145 * ports.c (scm_seek): don't reset the port buffers here.
147 * fports.c (fport_seek): reset the buffers, except for the
150 * strports.c (st_end_input): (bug fix): decrement pt->read_pos by
151 offset. check that it's not less than read_buf.
152 (st_seek): reset the buffers first, unless it's the 0 SEEK_CUR
153 case and currently reading.
155 1999-10-20 Gary Houston <ghouston@freewire.co.uk>
157 * ports.c (scm_seek): Add a special case for SEEK_CUR, offset 0,
158 so that unread chars are not needlessly discarded. (thanks to
161 1999-10-18 Gary Houston <ghouston@freewire.co.uk>
163 * fports.c (scm_fdes_to_port): always set rw_random if the fdes is
164 random access. rw_active needs to be maintained even for single
165 directional ports, otherwise scm_seek and probably other things are
166 broken. (thanks to Roland Orre).
168 * strports.c (scm_mkstrport): set rw_random to 1 unconditionally.
170 * ports.c (scm_add_to_port_table): initialise rw_random to 0.
172 * ports.h (scm_port): change the comments on rw_random and rw_active.
174 1999-10-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
176 * ioext.c: Added #include "feature.h".
178 These changes turns `delay' into a memoizing macro. This is
179 because it may be expanded before evaluation if it occurs at the
180 beginning of a body. (Thanks to Lauri Alanko.)
182 * eval.c, eval.h (scm_sym_delay): New global symbol.
184 * tags.h (SCM_IM_DELAY): New immediate symbol.
186 * print.c (scm_isymnames): Printed representation.
188 * eval.c (unmemocopy, SCM_CEVAL): Handle SCM_IM_DELAY.
189 (scm_m_delay): Turned into a memoizing macro.
191 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version.
193 1999-10-11 Jim Blandy <jimb@savonarola.red-bean.com>
195 * gh_data.c (gh_ints2scm, gh_doubles2scm): Make sure elements are
196 protected from GC while building the vector. (Thanks to Bernard
197 Urban and Greg Harvey.)
199 1999-10-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
201 * throw.c (handler_message): Display backtrace if backtraces
204 1999-10-05 Jim Blandy <jimb@savonarola.red-bean.com>
206 * Makefile.in, scmconfig.h.in: Deleted from CVS repository. Run
207 the autogen.sh script to create generated files like these.
209 * numbers.c (scm_string_to_number): Signal an error if radix is
210 less than two. (Thanks to Jorgen Schaefer.)
212 * print.c (scm_write, scm_display, scm_newline, scm_write_char):
213 Don't assume that the current output port is valid. Somebody
214 might close it. (Thanks to Bernard Urban.)
216 1999-10-02 Jim Blandy <jimb@zwingli.cygnus.com>
218 * scmconfig.h.in: Regenerated.
220 * Makefile.am (EXTRA_libguile_la_SOURCES): fix typo.
222 Mon Sep 27 17:15:14 1999 Greg J. Badros <gjb@cs.washington.edu>
224 * __scm.h: Fix a bunch of macros that were missing do-while(0)
227 * debug.c, eval.c: Fix buggy uses of SCM_ALLOW_INTS (missing
228 semicolon) exposed by the above change.
230 1999-09-27 Greg J. Badros <gjb@cs.washington.edu>
232 * stacks.c: Avoid compiler warning re: unitialized var.
234 * scmconfig.h.in: Added DEBUG_FREELIST
236 * pairs.h: Fix macro that was not do-while(0) sandwiched.
238 * gc.h, gc.c: Added scm_gc_set_debug_check_freelist_x,
241 1999-09-23 Gary Houston <ghouston@freewire.co.uk>
243 * ioext.c (scm_init_ioext): enable "i/o-extensions" feature here
244 instead of in scm_init_filesys.
246 * init.c (scm_boot_guile_1): don't call scm_init_posix or
247 scm_init_filesys unless HAVE_POSIX is defined.
248 don't call scm_init_netdb or scm_init_socket unless
249 HAVE_NETWORKING is defined.
251 * Makefile.am (EXTRA_libguile_la_SOURCES): filesys.c, posix.c,
252 net_db.c, socket.c: moved here from libguile_la_SOURCES.
254 1999-09-25 Jim Blandy <jimb@savonarola.red-bean.com>
256 * root.c (scm_make_root): Initialize all the fields of the new
257 root. GC could happen any time, you know. (Thanks to Greg
260 * numbers.c (scm_number_to_string): Signal an error if radix is
261 less than two. (Thanks to Jorgen Schaefer.)
263 * Makefile.am (EXTRA_libguile_la_SOURCES): Add memmove.c here,
264 so automake will actually generate rules for it.
265 * Makefile.in: Regenerated.
267 1999-09-21 Jim Blandy <jimb@savonarola.red-bean.com>
269 * backtrace.c: #include "_scm.h" before testing whether
270 HAVE_UNISTD_H is #defined.
272 1999-09-20 Jim Blandy <jimb@savonarola.red-bean.com>
274 * read.c (scm_read): Don't assume that scm_cur_inp is always open.
275 * ports.c (scm_read_char): Same.
276 * ioext.c (scm_read_line): Same.
277 (Thanks to Bernard Urban.)
279 1999-09-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
281 * vectors.c (scm_vector_move_right_x): Bugfix: Remove side effect
283 numbers.c: Removed #ifndef SCM_RECKLESS at places where type
284 checking may invoke a generic. (Thanks to Michael Livshin.)
286 * __scm.h (SCM_WTA_DISPATCH_0, SCM_GASSERT0): New macros.
288 * numbers.c (scm_max, scm_min, scm_sum, scm_difference,
289 scm_product, scm_divide): Bugfix: Don't pass SCM_UNDEFINED to the
290 generic function if the asubr is called with only one arg.
292 1999-09-20 Gary Houston <ghouston@freewire.co.uk>
294 * scmsigs.c (scm_sigaction): add SA_RESTART to flags only if
295 HAVE_RESTARTABLE_SYSCALLS.
296 (scm_init_scmsigs): use siginterrupt if it's available. not
297 everyone who has restartable syscalls has SA_RESTART it seems.
299 (scm_sigaction): use scm_num2long/scm_long2num when converting
300 SIG_DFL/SIG_IGN, in case it doesn't fit in an INUM. use
301 scm_integer_p to test the type.
303 1999-09-18 Gary Houston <ghouston@freewire.co.uk>
305 * _scm.h, scmsigs.c: replace HAVE_RESTARTS with
306 HAVE_RESTARTABLE_SYSCALLS.
308 * strports.c (scm_strport_to_string): create the string from
309 pt->read_buf instead of an expression that evaluates to the
312 * gdbint.c (gdb_print): don't just use SCM_CHARS to get a C string
313 from the port: the port's buffer may not be NUL terminated.
315 1999-09-16 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
317 * Makefile.am (.c.x): Added missing semicolon after `false'.
319 1999-09-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
321 * print.c (scm_iprin1): Turn `write' and `display' into
322 primitive generics and use their associated generic functions in
323 scm_iprin1 for GOOPS objects.
325 * backtrace.c: #include <unistd.h> if present.
327 1999-09-14 Jim Blandy <jimb@savonarola.red-bean.com>
329 * Makefile.am (.c.x): Don't create a subshell just to delete the
330 .x file and return false.
331 * Makefile.in: Regenerated.
333 1999-09-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
335 * feature.c (scm_create_hook): New function. Replaces
336 scm_make_named_hook which is now deprecated.
337 (scm_make_hook_with_name): New primitive.
338 (print_hook): Hooks now print in a fancy way.
340 1999-09-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
342 * __scm.h, backtrace.c, backtrace.h, debug.c, debug.h, dynl-dld.c,
343 dynwind.c, dynwind.h, eval.h, evalext.c, evalext.h, feature.c,
344 feature.h, hashtab.c, hashtab.h, objects.c, objects.h, print.c,
345 procs.c, procs.h, smob.c, smob.h, srcprop.c, strorder.c, struct.c,
346 struct.h: Updated copyright notices.
348 * srcprop.c (scm_source_property): Bugfix: Use SCM_NECONSP instead
349 of SCM_NCONSP. (Thanks to Greg Badros.)
351 * gsubr.c (scm_make_gsubr): Use scm_make_subr_opt for creation of
354 * eval.c, debug.h (SCM_BACKTRACE_WIDTH): New debug option: width.
356 * backtrace.c: Keep backtraces within specified width by
357 adaptively adjusting fancy printing parameters and cut output if
359 (scm_display_application): Check args.
361 1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
363 Change the name of the objects returned by OPENDIR from
364 "directory" to "directory stream". A predicate named "directory?"
366 * filesys.c (scm_directory_stream_p): Renamed from scm_directory_p.
367 At the Scheme level, "directory?" -> "directory-stream?".
368 (scm_dir_print): Use the phrase "directory stream" in printed form.
369 * filesys.h (scm_directory_stream_p): Prototype renamed
372 * Makefile.am (CLEANFILES): Remove versiondat.h; that should only
373 be removed by `make distclean', since it's generated by configure.
374 * Makefile.in: Regenerated.
375 (Thanks to Robert Bihlmeyer.)
377 * strop.c (scm_substring_move_x): Signal an error if start1
378 doesn't come before end1. (Thanks to Karoly Lorentey).
380 * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
381 calling SCM_NIMP. (Thanks to Karoly Lorentey).
383 * version.c (scm_libguile_config_stamp): Deleted. See
384 corresponding change to ../ice-9/boot-9.scm.
385 * versiondat.h.in: Remove definition for GUILE_STAMP.
386 * version.h: Delete prototype.
387 * Makefile.in: Regenerated.
389 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
391 * filesys.c (scm_directory_p): new procedure "directory?" Returns
392 a boolean indicating whether its argument is a directory
393 port as returned by opendir (thanks to Dirk Herrmann for the
396 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
398 * backtrace.c (display_frame_expr): Don't print a newline.
399 (display_frame): Print the newline here instead.
400 (display_backtrace_body): Don't print "Backtrace:".
401 (scm_backtrace): Print "Backtrace:" here instead.
403 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
405 * procs.c (scm_setter): Signal WTA if handed an entity or operator
408 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
409 primitives. (Thanks to Greg Badros);
410 (scm_hook_to_list): New primitive; Hooks are now smobs.
412 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
414 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
415 of #f for the 10th vector element to avoid an exception
416 seen by Bernard Urban.
417 (scm_mktime): unneeded ASSERT removed.
419 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
421 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
424 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
426 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
428 * numbers.c: Converted comparison operations to dispatch on
429 generic if args don't match.
431 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
433 1999-09-06 James Blandy <jimb@mule.m17n.org>
435 * guile-snarf.c: Deleted. Snarfing should respect CPP
436 conditionals, so it needs to actually run CPP. Bleah.
438 1999-09-05 James Blandy <jimb@mule.m17n.org>
440 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
441 * guile-snarf.in: Be sure to exit with an error if CPP does.
442 * Makefile.am (.c.x): Delete the .x file and exit with an error
443 status if guile-snarf exits with an error status.
444 * Makefile.in: Regenerated.
446 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
447 scm_makekey, which doesn't exist any more. Guess nobody's using
450 * guile-snarf.c: New implementation of guile-snarf, meant to be
451 more robust than the shell script. I think it's complete, but I
452 haven't tested it at all, and I haven't changed the build process
453 to actually use it. We should compare its output against that of
454 the existing shell script, for all source files.
456 * guile-snarf.c (parse_args): Abort if we haven't handled some
459 1999-09-03 James Blandy <jimb@mule.m17n.org>
461 * load.c (scm_search_path): If the filename has any extension at
462 all, ignore the entire list of extensions. Also, don't check whether
463 the file is accessible. If the file exists, accessible or not, we
464 should return it. Inaccessible files should cause an error later.
465 (Thanks to Keisuke Nishida for the suggestions.)
467 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
469 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
470 atexit not available. (sunos4.1.4 needs it.)
472 1999-09-01 James Blandy <jimb@mule.m17n.org>
474 I take it all back --- bcopy does handle overlapping source and
475 destination areas correctly. At least on every system I could
476 find. But it is better to use AC_REPLACE_FUNCS than to introduce
477 new CPP conditionals.
478 * memmove.c: New file, implementing memmove in terms of bcopy.
479 * scmconfig.h.in: Regenerated.
481 Allocators should use the `void *' type for generic pointers.
482 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
483 argument and return types.
484 * gc.h: Corresponding changes to prototypes.
487 1999-08-31 James Blandy <jimb@mule.m17n.org>
489 * numbers.c (scm_init_numbers): Claim to support the `complex'
490 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
492 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
493 find (ice-9 boot-9) when Guile was compiled in a separate
494 directory from the source. (Thanks to Rodney Brown.)
495 * Makefile.in: Regenerated.
497 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
498 table lengths by the size of a single element when growing the
499 table. (Thanks to Bill Schottstaedt.)
501 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
503 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
504 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
505 since that cuts down the time for type dispatch by 50%.
507 1999-08-30 James Blandy <jimb@mule.m17n.org>
509 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
510 not a correct substitute for memmove, because it doesn't handle
511 overlapping source and destination areas on many platforms.
512 Overlaps are the primary reason to use memmove in the first place.
513 * ports.c (scm_ungetc): Same.
514 * strop.c (scm_substring_move_x): Same.
516 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
518 * gc.c (scm_init_storage): Skip registration of cleanup on systems
519 which lack atexit. (Is it important that cleanup is made
520 properly? Maybe we should replace all `exit' with `scm_exit' and
523 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
524 scm_struct_free_standard, scm_struct_free_entity): Declared to
525 return scm_sizet instead of size_t.
527 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
528 there on sunos4.1.4.)
530 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
532 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
533 Account for the case when second argument is unbound.
535 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
536 (Thanks to Karoly Lorentey.)
538 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
539 isn't present. (Thanks to Suzuki Toshiya.)
541 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
544 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
547 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
548 Bernard Urban and Ian Grant.)
550 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
551 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
552 change in the representation of entities and operators.)
554 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
556 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
557 don't allocate zero bytes (thanks to Bill Schottstaedt).
559 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
561 * procs.c (scm_setter): Converted to use generic dispatch.
563 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
566 * load.c (scm_search_path): Don't try extensions which already are
567 present at the end of the filename.
568 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
570 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
572 Cleanup and simplification of generic method dispatch.
573 Also, the quadruple representation of entity and operator
574 procedures has been replaced with single.
576 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
578 * print.c (scm_isymnames): Removed #@hash-dispatch.
580 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
581 from eval.c; Support 0 arity methods.
582 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
583 (scm_apply_generic_env): Removed.
584 Replaced slots proc0-3 with procedure.
586 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
587 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
588 SCM_OPERATOR_PROCEDURE.
589 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
590 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
592 * struct.c, struct.h: Replace 4 procedure slots with one.
593 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
595 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
598 * eval.c (scm_sym_args): Removed.
599 (SCM_CEVAL): Simplified entity application.
600 Moved dispatch code to objects.c.
602 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
604 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
606 * sort.c (closureless): Use scm_eval_body.
608 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
609 with a symbol as last form was first called normally and then via
610 `map' or some other mechanism using primitive apply, an ILOC was
613 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
615 This change extends the representation of primitive procedures
616 with more data fields, e.g. a place for documentation and true
617 procedure properties.
619 * procs.c, procs.h (scm_subr_entry): New type: Stores data
620 associated with subrs.
621 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
622 SCM_SUBR_DOC): New macros.
623 (scm_subr_table): New variable.
624 (scm_mark_subr_table): New function.
626 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
628 * gc.c (scm_gc_mark): Don't mark subr names here.
629 (scm_igc): Call scm_mark_subr_table.
632 This change implements a scheme for letting a generic work as a
633 shadow for a primitive procedure. If the primitive procedure
634 can't dispatch on its arguments, control is left over to the
635 generic. Normal wrong type arg errors will be generated until the
636 user has hung the first method on the primitive.
638 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
640 * procs.c, procs.h (scm_subr_p): New function (used internally).
642 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
644 * objects.c, objects.h (scm_primitive_generic): New class.
646 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
648 * print.c (scm_iprin1): Print primitive-generics.
650 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
651 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
653 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
654 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
655 primitives). NOTE: This means that it is now *required* to use
656 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
657 obscured representation that will be removed in the future anyway,
658 so backward compatibility is no problem here).
660 * numbers.c: Converted most numeric primitives (all but bit
661 comparison operations and bit operations) to dispatch on generic
665 Better support for applying generic functions.
667 * eval.c, eval.h (scm_eval_body): New function.
669 * objects.c (scm_call_generic_0, scm_call_generic_1,
670 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
674 Optimization of the generic function dispatch mechanism.
676 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
677 called scm_memoize_method instead of doing a second lookup.
679 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
684 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
685 scm_sysintern so that the binding connected with the subr name
686 isn't cleared when we give set = 0.
689 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
691 More transparent handling of ports with print states.
693 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
694 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
695 instead of a pair of a port and a print state. We'll need to cons
696 once extra in scm_printer_apply but the type system will be
697 cleaner, it will mix better with GOOPS, and, it will be even more
698 transparent to the user.
700 * print.c (scm_get_print_state): New procedure: Given an output
701 port, return the print state associated to it in the current print
702 chain, if one exists;
703 (scm_port_with_print_state): New procedure: Associate a
704 print-state with a port.
705 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
706 (scm_printer_apply): Wrap port and pstate as a smob;
707 (print_state_printer): Removed.
709 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
711 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
714 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
715 testing (otherwise the port-print-state trick won't be transparent
716 to the user; one example where this caused problems was in the
717 (ice-9 format) module).
719 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
721 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
722 SCM_UNSPECIFIED instead of the set value.
724 1999-08-20 James Blandy <jimb@mule.m17n.org>
726 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
728 * ports.h (enum scm_port_rw_active): New enum, containing
729 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
730 zero). The debugger knows about enums, but doesn't know about
732 (typedef scm_port): Declare rw_active member to be an enum
734 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
736 * ports.c (scm_add_to_port_table): Same.
737 * strports.c (st_flush, st_end_input): Same.
739 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
740 scm_must_realloc, and scm_done_malloc as appropriate.
742 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
744 * sort.c (quicksort): Added condition to protect the algorithm
745 from crashing the interpreter if the less predicate is buggy.
747 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
749 * fports.c (fport_write): fix line-buffering mode again.
750 (scm_open_file): recognise 'l' for line-buffering.
751 (scm_setvbuf): recognise _IOLBF for line-buffering.
753 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
755 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
758 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
761 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
763 * fports.c (fport_write): use memcpy instead of strncpy, in case
764 the data contains NUL.
766 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
768 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
770 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
771 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
772 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
773 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
774 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
775 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
776 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
777 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
778 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
779 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
780 scm_sym_ as prefix for symbols.
782 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
784 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
785 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
786 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
787 scm_sym_atcall_cc): Made global.
789 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
791 * eval.c (scm_sym_args): Made global.
793 * objects.c (scm_set_object_procedure_x): Disallow setting of
794 procedures for pure generic functions.
796 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
798 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
799 Scheme name from lseek to seek, but lseek was added recently so
800 it shouldn't be a big problem.
801 * ports.c, gdbint.c, ioext.c: changed callers.
803 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
805 * fports.c (fport_input_waiting): if select is used, return 1
806 instead of whatever FD_ISSET expands to. maybe it will be useful
807 to interpret the value from the input_waiting ptob procedure as a
808 lower bound on the number of bytes available.
810 * Mikael asked for a few names to be changed...
812 * ports.c (scm_make_port_type): take the write procedure as the
813 second argument instead of the flush procedure.
814 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
815 fflush -> flush, read_flush -> end_input, fclose -> close,
816 fill_buffer -> fill_input, ftruncate -> truncate,
817 input_waiting_p -> input_waiting.
819 * ports.c (end_input_void_port): was read_flush_void_port.
820 (scm_set_port_end_input): was scm_set_port_flush_input.
821 (scm_set_port_flush): was scm_set_port_write.
822 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
823 (scm_end_input): was scm_read_flush.
824 (scm_fill_input): was scm_fill_buffer.
825 (scm_flush): was scm_fflush.
826 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
827 (fport_end_input): was local_read_flush.
828 (fport_flush): was local_fflush.
829 (fport_close): was local_fclose.
830 (fport_truncate): was local_ftruncate.
831 (fport_seek): was local_seek.
832 (fport_free): was local_free.
833 (fport_fill_input): was fport_fill_buffer.
834 * strports.c (st_end_input): was st_read_flush.
835 (st_truncate): was st_ftruncate.
836 * vports.c: (sf_flush): was sfflush.
837 (sf_close): was sfclose.
838 (sf_fill_input): was sf_fill_buffer.
840 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
843 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
845 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
846 forms now contain the expressions to be dispatched upon instead of
847 depending on a surrounding lambda or let; Generic function
848 dispatch has been optimized; `apply' on a generic function now
849 works a little bit strangely. It uses a trick so that the type
850 dispatch code in SCM_CEVAL can be reused.
852 * objects.h, objects.c (scm_apply_generic_env): Added (used by
854 (scm_operator_p): Added.
855 (scm_sym_atdispatch): Added.
856 (scm_set_object_procedure_x): Modified to handle the new style
858 (scm_object_procedures): New debugging procedure.
860 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
862 * eval.c, eval.h (scm_sym_args): Added.
864 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
866 * feature.c, feature.h (scm_c_run_hook): Added.
868 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
869 cdrxnoap and loopnoap instead of begin and loop.
871 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
873 * ports.c (scm_putc, scm_puts),
874 * unif.c (scm_uniform_array_write): use scm_lfwrite.
875 * ports.c (scm_putc): change type of first argument from int to char.
877 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
879 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
880 SCM_IM_HASH_DISPATCH.
882 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
883 (scm_si_redfined, scm_si_hashsets): Moved.
885 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
886 flag which combines type and status info so that the class
887 redefinition protocol has zero cost during normal execution.
889 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
891 * ports.h (scm_ptob_descriptor): include a write procedure again.
892 it's more efficient for unbuffered fports (e.g., sockets.)
894 * ports.c (scm_puts): use ptob->write.
895 * vports.c (scm_make_sfptob): set write proc in ptob.
896 * strports.c (scm_make_stptob): set write proc in ptob.
897 * ports.c (write_void_port): new procedure.
898 * vports.c (sf_write): new procedure.
899 * ports.c (scm_lfwrite): use ptob->write.
900 * strports.c (st_write): new procedure.
901 * fports.c (fport_write): new procedure.
902 (scm_make_fptob): set write in ptob to fport_write.
903 * ports.h: prototype for scm_set_port_write.
904 * ports.c (scm_make_port_type): initialise ptob write procedure.
905 (scm_set_port_write): new proc.
907 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
909 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
910 until we've verified that it is actually a port. (Thanks to
913 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
915 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
916 code, particularly an unnecessary test (len != size, where len ==
917 size). (Was this leftovers from debugging code, or have I missed
920 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
921 size. (Thanks to James Dean Palmer.)
923 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
924 (Thanks to Lorentey Karoly.)
926 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
928 * eval.c (scm_m_expand_body): Use scm_cons_source.
930 * struct.c (scm_print_struct): Use vtable name.
932 * print.c (scm_init_print): Set name of print state type.
934 * stacks.c (scm_init_stacks): Set name of stack type.
936 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
938 * eval.c (SCM_CEVAL): Removed old implementation of internal
941 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
943 * debug.c, debug.h (scm_reverse_lookup): Added.
944 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
945 internal procedure definitions; Don't use scm_i_inner_name.
947 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
950 * eval.h: Added prototypes for multi language support functions.
952 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
953 improper lists in the low-level representation, since that will
954 cause a begin to be prepended at macro expansion.
956 * eval.c (scm_cons_source): Version of cons which copies source
957 properties from an existing cell.
958 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
960 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
961 procedure source before calling scm_unmemocopy instead of faking
964 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
966 Ported `internal defines' fix from SCM. Original ChangeLog entry:
968 1998-07-09 Radey Shouman <radey@colorage.com>
970 * eval.c (ceval_1): Modifications to allow rewriting of interal
971 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
972 body of which it is the CAR is macro expanded by m_expand_body,
973 which rewrites internal DEFINE.
975 (m_expand_body): Added.
977 (m_macroexp1): Added argument to control error checking:
978 m_expand_body may speculatively expand forms in the wrong
979 environments. Made argument number checks conditional on
982 (m_body): Added, error checks bodies and inserts the ISYM tokens.
984 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
987 (m_cond): (m_case): (m_quote): Modified to avoid destructively
988 changing their argument forms. Since m_expand_body
989 speculatively macro expands forms the process must be
992 (m_ident_eqp): Fixed to use proper environment.
994 (renamed_ident): Added DEFER_INTS_EGC.
996 Added prototypes for static functions.
1002 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
1003 is false, do not produce an error for unbound variables, return a
1004 pointer to cell_undef instead.
1006 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
1010 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
1011 destructively changing their argument forms. Since m_expand_body
1012 speculatively macro expands forms the process must be reversible.
1014 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
1015 SCM_IM_LET introduced by named lets.
1017 (scm_m_letstar): Use scm_m_body instead of bodycheck.
1019 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
1020 scm_letrec. scm_letrec1 does not check for a null binding and
1021 takes an additional argument to specify the ISYM of the body. Use
1022 scm_m_body instead of bodycheck.
1024 (scm_m_let): Use scm_m_body instead of bodycheck.
1026 (scm_m_expand_body, scm_macroexp): New.
1028 (unmemocopy): Account for ISYMs introduced by scm_m_body.
1030 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
1031 check=1. Throw error for internal defined that have not been
1032 rewritten by scm_m_expand_body.
1034 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
1035 Removed prototype for SCM_APPLY.
1037 * tags.h: Added extern declaration of scm_isymnames.
1039 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1041 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
1043 * lang.c: New file: Beginning of multi-language support.
1045 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
1047 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
1048 (scm_dynamic_wind): Added argument checking for the after guard so
1049 that we don't add garbage on the dynwind chain.
1050 (scm_swap_bindings): Added.
1052 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
1053 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
1054 (scm_isymnames): New isyms for multi-language support.
1056 * eval.c (scm_nil, scm_t): New symbols.
1057 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
1058 forms for multi-language support.
1060 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1062 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
1064 Renamed functions in the random function library interface
1065 from scm_i_XXX --> scm_c_XXX.
1067 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
1069 * ports.c (scm_putc): fix line-buffering.
1071 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1073 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
1074 scm_set_ptob_XXX --> scm_set_port_XXX.
1076 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1078 * ports.c, ports.h (scm_make_port_type): New interface for
1079 creation of port types (replaces scm_newptob). Just as for the
1080 smobs, we need to separate the internal representation of smob
1081 types from the interface, so that we easily can add new fields and
1082 rearrange things without caring about backward compatibility.
1083 This change was forced by the need in GOOPS to create classes
1084 representing port types.
1085 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
1086 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
1087 scm_set_ptob_seek, scm_set_ptob_truncate,
1088 scm_set_ptob_input_waiting_p): New setters.
1089 (scm_newptob): Rewritten to use scm_make_port_type. For backward
1091 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
1092 (scm_prinport): Removed.
1093 (scm_port_print): Added.
1094 (scm_print_port_mode): Added.
1095 (void_port_ptob, print_void_port, close_void_port, noop0):
1096 Removed. Removed #include "genio.h" Added #include "objects.h",
1099 * fports.c (prinfport): Moved code from ports.c.
1100 (local_free): Added.
1101 (scm_fptob): Removed. Instead use new interface.
1102 (scm_make_fptob): Added. (Need to create basic ports in a
1103 specific order in ports.c.)
1105 * strports.c (scm_stptob, prinstpt, noop0): Removed
1106 (scm_make_stptob): Added.
1108 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
1109 (scm_make_sfport): Added.
1111 * filesys.c (scm_dir_print): Don't use the port printing code.
1112 Instead provide specific directory printer.
1114 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
1116 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
1117 scm_ptob_descriptor.
1119 * smob.c (scm_smob_print): Handle non-existing type name nicely.
1120 Removed #include "genio.h"
1122 * objects.c (scm_make_port_classes): New function ptr.
1124 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
1126 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
1128 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
1129 allow the 1st argument to be a fdes or filename as well as a
1130 port (as in the filesys.c version).
1132 * filesys.c (scm_truncate_file): removed.
1134 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1136 * readline.c, readline.h: Removed.
1138 * objects.c, objects.h (scm_port_class): Added.

1148 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1150 * init.c: Make sure that scm_post_boot_init_modules is called only
1151 once. (Important when using a dumped image.; Thanks to Bernard
1154 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
1156 * guardians.c (scm_guardian_zombify): Separate scanning for
1157 zombies from marking the pairs of the free list.
1159 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
1160 use the macros. (Thanks to Michael Livshin.)
1162 * eval.c (scm_m_lambda): Let bodycheck check the body of the
1163 lambda. Let your sins be purified by the blood of the lambda.
1164 (Thanks to Eric Hanchrow.)
1166 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
1167 (Thanks to Valdis Kletnieks.)
1169 Fixes for EMX from Mikael Ståldal.
1171 * filesys.c: #include <io.h>, if we have it.
1172 * scmconfig.h.in: Regenerated.
1174 * stime.c (ftime): Delete declaration for this function --- let
1175 the system supply it.
1177 Cleanups from John Bley.
1179 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
1181 * gsubr.c: Don't include "gsubr.h" twice.
1183 Cleanups for compilation on Irix 6, from David Kaelbling.
1185 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
1186 regex_t pointer. This is what the callers have, mostly.
1187 (scm_regexp_exec): Don't forget to pass the `rx' argument to
1188 scm_regexp_error_msg.
1190 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
1191 int. That way, if we get a warning on this line, it's more likely
1192 that we're really missing bits we care about.
1194 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
1197 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
1198 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
1199 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
1200 cast at all is more appropriate in every case. At the moment, we
1201 assume everywhere that SCM is an integral type anyway.
1203 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
1205 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
1206 read_pos after scm_fill_buffer.
1208 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
1211 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
1212 fports.c (fport_fill_buffer): implement the interface change.
1214 * ports.c (scm_fill_buffer): interface change: no longer increments
1215 read_pos past the character that's returned. it seems clearer to
1216 leave it to the caller to decide what to do (thanks Jim).
1218 * vports.c (sf_fill_buffer): put the read char into the buffer
1219 as well as returning it.
1221 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

1226 * strports.c (scm_strprint_obj): simplify. start with initial
1228 (st_seek): don't allow string to be extended if seeking past

1235 * ports.c (scm_ftruncate): throw error if offset works out negative.
1237 * strports.c (st_flush): increase string size in blocks of
1238 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
1239 it's greater and reset read_buf_size.
1240 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
1241 to be maintained for output ports too (it holds the written
1242 part of the string, while write_buf may have unwritten buffer
1244 (st_truncate): rewritten.
1245 (top of file): added a few notes.
1247 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
1249 Patch from Greg Badros:
1250 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
1251 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
1252 (function pointer) argument to scm_make_gsubr and scm_make_subr
1253 calls. This avoids warnings in C++ programs using guile-snarf.
1255 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
1257 * strports.c (st_grow_port): set pt->read_pos. set
1258 pt->read_buf_size one less than pt->write_buf_size if there's
1259 an unwritten char at the end of the string. similarly for
1261 (st_resize_port): renamed from st_grow_port.
1262 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
1263 seek from read_end instead of write_end for SEEK_END.
1264 (st_ftruncate): calculate current length using readbuf, not write
1266 (scm_strport_to_string): use read_buf_size for length.
1267 (stfill_buffer): don't re-initialise the readbuf.

1282 * smob.c: added scm_make_smob_type_mfpe (), scm_set_smob_mfpe ();
1283 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
1284 and "bigneg" smob types.
1286 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
1287 SCM_RETURN_NEWSMOB macro. Added protos for new functions in
1290 * *.c: Use scm_make_smob_type_mfpe, instead of scm_newsmob, and
1291 use SCM_NEWSMOB or SCM_RETURN_NEWSMOB in constructors instead of
1292 SCM_NEWCELL and setting the CAR/CDR by hand.

1376 trinary conditional in order for the flag computation to be
1379 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1381 * struct.c, struct.h:
1383 In order to support different kinds of deallocation, a destructor
1384 slot has been added to struct vtables. This allows for structs
1385 containing pointers to other memory blocks.

1459 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1460 around the condition of an `if', `while', etc., even if the
1461 condition is a macro invocation that expands to something
1462 surrounded by parens. It's more readable.
1464 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1465 proper lists, and of the appropriate lengths.
1466 (check_map_args): New function. (Thanks to Greg Harvey for the
1469 1999-06-19 Michael Livshin <mike@olan.com>

1508 vectors without allocating new storage during GC, using
1509 scm_weak_vectors as the head of the chain.
1510 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1511 instead of stepping through an array.

1524 * fports.c (local_seek): Signal an error if the seek fails.
1525 * ports.c (scm_lseek): Don't check return value of port's seek

1540 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1542 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1543 it shows up as terrible performance, as we GC constantly.
1545 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1546 newline. A bit faster, and definitely hairier.

1560 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1561 and there's a newline to be written, flush the port.
1563 Gary Houston's open-buffer port patches:
1565 1999-04-26 Gary Houston <ghouston@easynet.co.uk>

1589 ports.c (scm_init_ports): initialise the seek symbols here
1590 instead of in ioext.c.
1591 strports.c (scm_call_with_output_string): start with an empty
1592 string, so seek and ftruncate can be used.
1594 gdbint.c: adjust string port usage.
1596 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1598 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1599 equivalent to fflush for the read buffer.
1600 * ports.c (scm_newptob): set read_flush.
1601 ports.c (void_port_ptob): set read_flush.
1602 fports.c (local_read_flush): new proc. add to ptob.
1603 strport.c (st_read_flush): likewise.
1604 vport.c (sf_read_flush): likewise.
1605 fports.h (struct scm_fport): remove random member. there's nothing
1606 left but fdes. leaving it as a struct to allow for future changes.
1607 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1608 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1609 ptob proc if the read buffer is filled.
1611 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1613 * ports.h (scm_port): add a rw_random member and replace
1614 reading and writing members with rw_active member.
1615 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1617 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1619 * ports.h (struct scm_port_table): add writing and reading members
1620 to replace write_needs_seek: it isn't good enough for non-fports.
1621 ports.c, ioext.c, fports.c: corresponding changes.
1622 (struct scm_port_table): give it a typedef and rename to scm_port.
1623 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1624 corresponding changes.
1626 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
1628 * ports.c (scm_newptob): bugfix: set seek member.
1629 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
1630 and generalised to all port types.

1634 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1635 signals (it was only being done for handlers installed from Scheme).
1636 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1637 waiting for input caused an EINTR error from read.
1639 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1641 * ports.h (struct scm_port_table): make all the char members
1642 unsigned, so they convert to int without becoming negative if large.
1644 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1646 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1647 with threads enabled. rename this procedure to
1648 fport_wait_for_input and take a port instead of a fdes.
1649 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1651 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1652 get readline support working again: use fdopen to get FILE objects.
1654 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1656 * gc.c (scm_init_storage): install an atexit proc to flush the
1658 (cleanup): the new proc. it sets a global variable which can be
1659 checked by the ptob flush procs to avoid trying to throw
1660 exceptions during exit. not very pleasant but it seems more reliable.
1661 * fports.c (local_fflush): check terminating variable and if set
1662 don't throw exception.
1663 * CHECKME: that the atexit proc is installed if unexec used.
1665 * throw.c (scm_handle_by_message): don't flush all ports here.
1666 it still causes bus errors.
1668 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1669 and move to ioext.c.
1671 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1673 * ports.c (scm_char_ready_p): check the port buffer and call the
1674 ptob entry if needed.
1676 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1677 ptob initialisers. use it in char-ready
1679 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1681 * vports.c (sfflush): modified to write a char (since softports
1682 currently use shortbuf.)
1684 * fports.c (scm_standard_stream_to_port): moved to init.c and
1687 * init.c (scm_init_standard_ports): make stdout and stderr
1688 unbuffered if connected to a terminal. with stdio they
1689 were line-buffered by default.
1691 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1694 * ports.h (scm_ptobfuns): change fflush return to void.
1695 change flush proc definitions.
1697 * strports.c (scm_call_with_output_string): get size from
1698 buffer instead of port stream.
1699 (st_flush): new proc.
1701 * ports.h (struct scm_port_table): added write_end member,
1702 as an optimisation. set it where write_buf_size is set.
1704 * ports.h (struct scm_port_table): change stream from void *
1705 back to SCM. SCM presumably must be large enough to hold a
1706 pointer (and probably vice versa but who knows.)
1707 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1709 (scm_puts): rewritten
1710 * fports.c (local_ffwrite, local_fputs): removed.
1711 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)

1718 * fports.c (local_fputc): deleted.
1720 * ports.c (scm_add_to_port_table): initialise write_needs_seek.
1722 * ports.h (scm_ptobfuns): add seek function pointer.
1723 * fports.c: set it to local_seek, new procedure.
1726 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1727 use ptob for seek. take ptob instead of fport arg.
1729 * ports.h (struct scm_port_table): new member write_needs_seek,
1730 replaces reading member in fport struct.
1732 * vports.c (sfgetc): store the getted char into the buffer.
1733 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1734 the Scheme interface is still a procedure that gets a char.
1735 (scm_make_soft_port): set up the port buffer (shortbuf).
1737 * fports.c (local_fgetc, local_fgets): deleted.
1738 * strports.c (stgetc): likewise.

1742 * ports.c (scm_newptob): assign it.
1743 * strports.c (scm_mkstrport): set up the buffer.
1744 put just the string into the stream, not cons (pos stream).
1745 (stfill_buffer): new proc.
1747 * ports.h: fport buffer moved into port table: to be
1748 used for all port types.

1819 ports.c fports.c ioext.c posix.c socket.c net_db.c filesys.c:
1820 removed all uses of SCM_DEFER/ALLOW ints for now. they were mainly
1821 just protecting errno. some may need to be put back.

1949 (substring-move-left!, substring-move-right!): These are
1950 now just synonyms for substring-move!.
1951 * strop.h (scm_substring_move_x): New prototype.
1952 (scm_substring_move_left_x, scm_substring_move_right_x):
1953 #define these as synonyms for scm_substring_move_x.

2069 scm_misc_error when pos is a string. This allows for dispatching
2070 arbitrary error messages with one argument via SCM_ASSERT:

2079 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2081 Most of this batch of changes is about how to deal with extended
2082 types when an object system is loaded into Guile. A nice object
2083 system is capable of representing Guile's types as class objects.
2085 For example, we want a regular expression to be of class <regex>.
2086 But regular expressions are smobs which aren't under direct
2087 control of the object system, so there has to be some mechanism
2088 which informs the object system that a new class should be created
2089 which can represent the smob type. I call this a "wrapper class".
2091 * objects.c: #include "smob.h";
2092 (scm_class_keyword): Removed. (Class is automatically created by
2094 (scm_smob_class): Array of smob classes indexed by smobnum.
2095 (scm_make_extended_class): "Plugin" function pointer for creation
2096 of wrapper classes for smob and struct types.
2097 (scm_class_of): Handle compiled closures. (Currently regarded as
2099 Use scm_smob_class to handle smob types;
2100 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
2101 through scm_smob_class;
2104 * smob.c (scm_newsmob): Also create a wrapper class if
2105 scm_smob_class has been initialized.
2107 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16

2114 (scm_struct_create_handle): Get/create entry in scm_struct_table.
2115 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
2116 for accessing names of vtables. The record implementation in
2117 boot-9.scm currently uses the setter to record the name of record
2118 types. When the object system is initialized, it can use this
2119 information to create wrapper classes with suitable names.
2120 (scm_init_struct): Allocate scm_struct_table.
2121 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
2122 (struct tags are a finite resource and we might want to restrict
2123 the use of tags to vtables only. E.g., Goops only uses tags for
2125 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
2127 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
2130 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
2131 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
2132 Used for access of struct table entries.
2134 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
2135 (scm_hash_fold): New procedure. Used to process all entries in a
2136 hash table (in no particular order).
2138 Argh! For the umpteenth time I got compilation errors because of
2139 the "intuitive" name `kw'. This has to have an end:
2141 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
2142 "kw" --> "keywords" everywhere.
2143 (I doubt that this will cause big compatibility problems since the
2144 application interface is unaffected.)
2146 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
2148 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2150 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
2151 column inums to native form.
2153 Improvement of backtraces: Introduces a new stack narrowing
2154 specifier, #t, for the inner cut. (See further in the comments in

2295 SYMB now point to const.
2297 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2299 * print.c (scm_iprin1): Use scm_procedure_name instead of
2300 scm_procedure_property for compiled closures.
2302 * tags.h (scm_tc7_pws): New procedure type. Four representations
2303 for procedure-with-setters were considered before selecting this
2306 1. A closure where the CODE and ENV slots are used to represent
2307 the getter and a new SETTER slot is used for the setter. The
2308 original getter is stored as a `getter' procedure property. For
2309 closure getters, the CODE and ENV slots contains a copy of the
2310 getter's CODE and ENV slots. For subr getters, the CODE contains
2313 2. A compiled closure with a call to the getter in the cclo
2314 procedure. The getter and setter are stored in slots 1 and 2.
2316 3. An entity (i.e. a struct with an associated procedure) with a
2317 call to the getter in the entity procedure and the setter stored
2318 in slot 0. The original getter is stored in slot 1.
2320 4. A new primitive procedure type supported in the evaluator. The
2321 getter and setter are stored in a GETTER and SETTER slot. A call
2322 to this procedure type results in a retrieval of the getter and a
2323 jump back to the correct eval dispatcher.
2325 Representation 4 was selected because of efficiency and
2328 Rep 1 has the advantage that there is zero penalty for closure
2329 getters, but primitive getters will get considerable overhead
2330 because the procedure-with-getter will be a closure which calls
2333 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
2334 <procedure-with-setter>, but together with rep 2 it suffers from a
2335 three level dispatch for non-GOOPS getters:
2337 cclo/struct --> dispatch proc --> getter
2339 This is because the dispatch procedure must take an extra initial
2340 argument (cclo for rep 2, struct for rep 3).
2342 Rep 4 has the single disadvantage that it uses up one tc7 type
2343 code, but the plan for uniform vectors will very likely free tc7
2344 codes, so this is probably no big problem. Also note that the
2345 GETTER and SETTER slots can live directly on the heap, using the
2346 new four-word cells.
2348 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

2589 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2590 boot-9.scm for a while); First arg is the hook. The rest are
2591 arguments passed on to the hook procedures.
2593 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2595 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2596 scm_logbit_p): Do the computation in ulongs. This is not as nice
2597 as doing it in bignums, but at least it's good enough for
2598 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2600 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2601 subexpressions. (Thanks to Charbel Jacquin.)
2603 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2605 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2606 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2607 (scm_make_named_hook): New function.
2609 * feature.c: Added #include "eval.h".
2611 * modules.c (scm_make_module): Beautify the module.
2613 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2615 * modules.c, modules.h: New files: C interface to modules. (This
2616 is necessary in order to interface the object system to Guile
2617 properly. The guts of these modules will be replaced by the new
2618 module system in the future.)
2620 * init.c: Added #include "modules.h"
2621 (scm_boot_guile_1): Call scm_init_modules.
2622 (invoke_main_func): Call scm_post_boot_init_modules.
2624 * Makefile.am: Added modules.c, modules.x, modules.h.
2626 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2628 * procs.c: #include "objects.h"
2629 (scm_procedure_p): Return #t also on structs which are operators.
2631 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2632 <operator-metaclass> and <entity-class> to <standard-class>,
2633 <operator-class> and <entity> in order to conform with STKlos
2636 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2637 which isn't an operator.
2638 (SCM_APPLY): Ditto, but jump to badproc.
2640 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2642 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2643 Previously, structs implanted in code were interpreted as forms
2644 the operator of which was a gloc. We solve this by checking for
2645 the zero in the emulated vcell in the struct vtable. Since
2646 implanted structs always will look like forms with a gloc
2647 operator, execution will only be slowed down by maximally one
2648 extra test-and-branch per application.
2650 * evalext.c (scm_definedp): Removed check for isyms; Added a
2651 second optional argument: It is now possible to supply an
2652 evaluation environment in which to look for the symbol.
2654 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2656 * readline.c (scm_init_readline): Set
2657 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2659 * coop.c (coop_condition_variable_wait): Removed
2660 (coop_condition_variable_wait_mutex): Folded logic of
2661 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2662 prevent condvar signal lossage. Previously, another thread could
2663 start to run after unlocking the mutex but before putting the
2664 current thread on the wait queue. If that thread then would
2665 signal the first, the signal would be lost. (Thanks to Christian
2668 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2670 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2673 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2675 * objects.c (scm_i_make_class_object): Renamed from
2676 make_class_object; exported; error checking moved to
2677 scm_make_class_object and scm_make_subclass_object.
2678 (scm_make_class_object, scm_make_subclass_object): Use
2679 scm_i_make_class_object.
2680 (scm_make_subclass_object): Let the subclass have same metaclass
2683 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2685 * debug.c (scm_debug_options): Bugfix: Set the value of
2686 scm_stack_checking_enabled_p after setting debug options;
2687 #include "stackchk.h". (Thanks to Richard Polton.)
2689 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2691 * unif.c (scm_array_contents): removed unnecessary test for 0
2694 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2696 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2697 Replaced by macro `collect' in boot-9.scm.
2699 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2701 * eval.c (scm_copy_tree): Copy source properties if existent.
2703 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2704 don't, we may end up passing memoized source to a transformer.)
2706 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2708 * stack.c (get_applybody): Help function which lookups the first
2709 body form of the apply closure.
2710 (read_frames): Prevent the source of the first form of the apply
2711 closure from being recorded. This would only be confusing.
2713 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2714 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2716 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2718 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2720 (read_frames): Use SCM_MACROEXPP.
2722 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2724 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2725 don't contain interesting information since all arguments are
2726 present in the frame which applies the compiled closure anyway.);
2727 Skip the transformer application frames.
2729 * print.c (scm_iprin1): Print gsubrs as primitives.
2731 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2733 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2735 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2736 that we can identify these in a backtrace. (This change doesn't
2737 introduce any significant speed penalty.)
2739 * eval.c: Added note about `serial-map' using scm_map.
2741 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2742 readline options. They should reside in their own options array.
2744 * readline.c, readline.h (scm_readline_options,
2745 scm_readline_opts): Moved readline options here.
2747 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2749 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2750 SCM_ROCHARS instead of SCM_CHARS.
2752 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2753 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2755 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2757 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2758 This is quite important since the latter clears the
2759 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2760 every single character read...
2762 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2764 * print.c (scm_iprin1): Removed suspect looking (and indeed
2765 malevolent) semicolon after test for user supplied closure print
2766 procedure. (Thanks to Telford Tendys.)
2768 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2769 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2770 starting to search the list. Removed call to sloppy_mem_check.
2772 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2773 procedures: Same as scm_delq_x et al, but delete maximally one
2776 * options.c (scm_options, scm_init_options): GC-protect option
2777 values of type SCM. (Thanks to Telford Tendys.)
2779 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2781 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2782 make sure that there always is a "real" scm_lookupcar.
2784 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2786 * read.c, read.h (scm_read_opts): New read options
2787 "history-length" and "history-file".
2788 (scm_read_options): Stifle history to history length.
2790 * readline.c (scm_read_history, scm_write_history): New procedures.
2792 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2794 * eval.h (scm_macro_eval_x): Removed declaration.
2796 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2797 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2798 Renamed and made global.
2800 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2801 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2803 * evalext.c, evalext.h: New files. Contain non-R5RS things
2804 having to do with evaluation.
2806 * evalext.c (scm_serial_map): New procedure: Version of `map'
2807 which guarantees that the procedure is applied to the lists in
2809 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2810 returns a list of the results of the body forms instead of the
2811 result of the last body form.
2812 (scm_definedp, scm_m_undefine): Moved from eval.c
2814 * evalext.h (scm_m_sequence_to_list): Added declaration.
2816 * macros.c, macros.h: New files.
2817 (scm_procedure_to_syntax, scm_procedure_to_macro,
2818 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2819 scm_macro_name, scm_macro_transformer): Moved from eval.c
2820 (scm_make_synt): Moved from eval.c
2822 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2824 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2827 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2829 * debug.c, print.c: Added #include "macros.h".
2831 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2833 This change adds the ability to use `unread-char' multiple times
2834 without interspersed reads and adds the new procedure
2835 `unread-string'. The change is optimized for the common case of
2836 unreading a single character. This is also the reason behind the
2837 choice to store characters in the port itself: in most cases no
2838 extra malloc is required.
2840 The amount of code in some macros in ports.h has been increased to
2841 the extent that they would fit better as C functions, but, since
2842 this code belongs to the port representation, such functions
2843 should be placed in ports.c which would cause calls back and forth
2844 between ports.c and genio.c. That is not good for performance.
2845 Also, keeping them as macros allows the compiler to do some
2846 optimizations which are needed to make the current interface
2847 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2849 One benchmark (Guile startup time) indicates an increase of
2850 loading speed of 1%. Another (reading (using `read') boot-9.scm
2851 10 times) shows no change in performance.
2853 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2854 made to find a beautiful solution.)
2856 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2857 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2858 character. (SCM_CLRDY clears all.)
2859 (SCM_N_READY_CHARS): New macro: Returns number of unread
2860 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2861 (struct scm_port_table): New fields: `entry' contains port table
2862 index, `cp' points to last unread char, `cbuf' is the buffer for
2863 unread chars, `cbufend' points after end of the character buffer.
2865 * ports.h, ports.c (scm_unread_string): New procedure.
2866 (scm_grow_port_cbuf): New function.
2868 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2870 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2871 to read unread characters. Use SCM_TRY_CLRDY instead of
2874 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2876 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2878 * genio.c, genio.h (scm_ungets): New function.
2880 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2883 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2885 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2886 declarations. (Thanks to Russ McManus.)
2888 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2890 * numbers.c (num2long): As a software archeologist, I'm proud of
2891 this finding! :) Preliminary dating suggests an almost 4 year old
2892 remnant from the SCM ancestor. The sample has been removed from
2893 the finding site and is now safely stored in the repository.
2895 * numbers.h: Removed prototype for num2long.
2897 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2899 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2900 array as second arg.
2901 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2902 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2903 * gh.h: Updated and added prototypes.
2905 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2907 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2909 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2911 * guile-snarf.in: Never generate an empty file. (Thanks to
2914 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2915 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2916 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2917 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2918 gh_new_procedure5_0): Specify argument types, to appease C++
2919 compilers. (Thanks to Brad Bowman.)
2921 Bug reports from Russ McManus:
2922 * guile-snarf.in: If the CPP environment variable is set, use that
2923 as the C preprocessor, instead of the preprocessor autoconf
2925 * snarf.h (SCM_PROC): Cast the function pointer passed to
2926 scm_make_gsubr, to satisfy C++.
2928 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2929 Use the handler passed, instead of ignoring it and using
2930 gh_standard_handler. (Thanks to Etienne Bernard.)
2932 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2934 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2937 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>
2939 * __scm.h, alist.c, async.c, async.h, backtrace.h, chars.c,

2954 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2957 * script.c (scm_compile_shell_switches): Define
2958 use-emacs-interface in the root module, so the repl code can see
2959 it. See today's change to top-repl in ice-9/boot-9.scm.
2961 * filesys.c (set_element, get_element): Make sure that `element'
2962 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2963 Boekemeier and Jorgen "forcer" Schaefer.)
2965 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2967 * chars.c (scm_charnames): In ASCII character name table, make
2968 newlines print as #\newline by default, not #\nl.
2970 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2971 alphabetical order. Oh thrills. But it helps me know how far
2972 along in the compilation I am.
2973 * Makefile.in: Regenerated.
2975 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2977 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2978 #bytes(...) to #y(...), and syntax for short vectors from
2979 #short(...) to #h(...). This may seem nutty, but, like the other
2980 uniform vectors, byte vectors and short vectors want to have the
2981 same print and read syntax (and, more basic, want to have read
2982 syntax!). Changing the read syntax to use multiple characters
2983 after the hash sign breaks with the conventions used in R5RS and
2984 the conventions used for the other uniform vectors. It also
2985 introduces complexity in the current reader, both on the C and
2986 Scheme levels. (The Right solution is probably to change the
2987 syntax and prototypes for uniform vectors entirely.)
2989 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2991 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2992 (Thanks to Jorgen "forcer" Schaefer.)
2993 * ports.h (SCM_NOFTELL): New flag.
2994 * fports.c (local_fgets): If it's set, use the generic fgets.
2995 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2997 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2999 * script.c (scm_compile_shell_switches): Add handling of -q switch
3000 (inhibit loading of user init file).
3001 (scm_shell_usage): Add usage text for -q switch.
3002 (scm_compile_shell_switches): Always load user init file first if
3003 it is loaded at all.
3005 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
3007 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
3008 and is now broken under NetBSD. I can't fathom what it's trying
3009 to do, so I've replaced it with something that I do understand,
3010 which seems to work, and which isn't broken on NetBSD. "Progress?
3011 You Decide." (Thanks to Perry Metzger.)
3013 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
3014 signed/unsigned comparison.
3016 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
3018 Warning fixes from Greg Harvey:
3019 * unif.c (scm_array_set_x): initializer for pos
3020 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
3021 * struct.c (scm_struct_ref, scm_struct_set_x): Added
3022 initializers for field_type, since EGCS so desparately wants to
3024 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
3025 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
3026 when GUILE_DEBUG is defined.
3027 * dynwind.h (scm_wind_chain): Same.
3028 * ports.h (scm_pt_size, scm_pt_member): Same.
3029 * print.h (scm_current_pstate): Same.
3030 * procs.h (scm_make_cclo): Same.
3032 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
3034 Handle short and long long uniform arrays properly. (Thanks to
3036 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
3037 raeql_1): Add cases for scm_tc7_svect (short vectors) and
3038 scm_tc7_llvect (long long vectors).
3040 Change the way libguile and boot-9.scm are timestamped, to try to
3041 get rid of these spurious mismatch warnings. Now both
3042 libguile/versiondat.h and ice-9/version.scm are generated directly
3043 by the configuration process, rather than having version.scm
3044 generated directly, and libguile/versiondat.h generated by the
3045 Makefile, which is generated by configure. It seems that
3046 sometimes the Makefile would change, but versiondat.h depends on
3047 Makefile.in, not Makefile, so it wouldn't get rebuilt.
3048 * Makefile.am (versiondat.h): Target removed; this is generated
3049 directly by the configure script now.
3050 (BUILT_SOURCES): Remove versiondat.h.
3051 * versiondat.h.in: New file, transformed by the configure script
3053 * Makefile.in: Regenerated.
3055 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
3056 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
3057 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
3058 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
3059 if we want to use them in a header file some day, we can. (Thanks
3060 to Michael Livshin.)
3062 * stime.c (scm_get_internal_real_time): Do the arithmetic using
3063 SCM numbers, so we won't have rollover problems; the range of a
3064 signed long in milliseconds is about 25 days. (Thanks to Karl
3067 Don't redefine sleep and usleep; fix this problem now.
3068 * coop.c (sleep, usleep): Remove declarations; we don't use or
3069 redefine these any more.
3070 (scm_thread_usleep, scm_thread_sleep): New functions which do the
3071 job of usleep and sleep in a thread-friendly way. We can use
3072 these in the rest of Guile. Define versions for systems both with
3073 and without iselect.
3074 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
3075 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
3076 we're just using it, not redefining it, we can use a K&R style
3078 (sleep): Declare this, too, if the system hasn't.
3079 (scm_sleep, scm_usleep): Use scm_thread_sleep and
3080 scm_uthread_sleep if they're available; otherwise, just call the
3082 * scmconfig.h.in: Regenerated.
3084 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
3086 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
3088 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
3090 * threads.c: Doc fix.
3092 The argument type of usleep varies from system to system,
3093 as does the return type. We really shouldn't be redefining usleep
3094 at all, but I don't have time to clean that up before the 1.3.
3095 release. It's on the schedule for afterwards. (Thanks to Julian
3097 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
3099 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
3100 * scmconfig.h: Regenerated.
3102 * simpos.c (scm_software_type): Procedure deleted. This isn't the
3103 right way to handle system variation. Autoconf's approach is the
3105 * simpos.h (scm_software_type): Declaration deleted.
3107 * script.c (scm_find_executable): Don't test if unix is #defined
3108 here; first, NetBSD doesn't #define it, and second, it's the wrong
3109 way to go about these things. (Thanks to Perry Metzger.)
3110 (dld_find_executable): Delete this MSDOS support code. This isn't
3111 the way we want to support this; it needs to be rethunk at a
3114 * genio.c (scm_do_read_line): Don't just politely check that the
3115 line was either non-empty or EOF. Abort if it's empty and not
3118 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
3120 * scmconfig.h.in: Regenerated.
3122 * libguile.h: Don't omit the dynamic linking functions. (Thanks
3125 * genio.c (scm_do_read_line): Count lines correctly when the file
3126 doesn't end in a newline.
3128 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
3130 * genio.c (scm_do_read_line): Maintain the line count correctly.
3131 (Thanks to Harvey J. Stein and Greg Harvey.)
3133 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
3136 * numbers.c (big2str): Protect t from garbage collection until
3137 we're done. (Thanks to Gary Houston.)
3139 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
3141 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
3143 * Makefile.in: Regenerated.
3145 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
3146 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
3149 Do magic to mix reads and writes on stdio FILE-based ports.
3150 (Thanks to Christian Lynbech.)
3151 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
3153 (pre_read, pre_write): New functions.
3154 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
3155 local_fputs): Call them.
3156 (local_fflush): Mark the port as ready for reading and writing.
3157 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
3158 flags on new port objects. This might not be accurate --- who
3159 knows what state the FILE * is in when we get it --- but it won't
3160 do extraneous calls to fflush or fseek, so it's no worse than the
3161 behavior before this change.
3162 * ports.h: Add comment.
3164 Centralize the creation of port objects based on stdio FILE * in
3165 fports.c; don't just throw them together anywhere.
3166 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
3167 what the rest of Guile wants. Don't set the revealed count;
3168 that's only appropriate for stdin, stdout, stderr.
3169 (scm_standard_stream_to_port): This function does set the revealed
3171 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
3172 not scm_stdio_to_port.
3173 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
3174 * fports.c (scm_open_file): Same.
3175 * posix.c (scm_pipe): Same.
3176 * socket.c (scm_sock_fd_to_port): Same.
3177 * ioext.c (scm_fdopen): Same.
3178 (scm_freopen): Moved from here to...
3179 * fports.c (scm_freopen): ... here. This is really something that
3180 munges the internals of an fport, so it should go here.
3181 * fports.h (scm_stdio_to_port): Adjust prototype.
3182 (scm_standard_stream_to_port, scm_freopen): New protoypes.
3183 * ioext.h (scm_freopen): Prototype removed.
3185 * filesys.c (set_element, get_element): This can work on both pipe
3186 and file ports, so use SCM_FPORTP to typecheck, instead of testing
3189 * scmconfig.h.in: Regenerated.
3191 Change the definition of the functions in scm_ptobfuns so that
3192 they get passed the port object, not the port's stream.
3193 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
3194 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
3195 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
3196 Pass the port itself to the scm_ptobs function.
3197 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
3198 scm_generic_fgets): Same.
3199 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
3200 getc_void_port, fgets_void_port, close_void_port): Just change the
3201 argument names; these functions don't really do anything.
3202 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
3203 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
3204 port as an argument, and use SCM_STREAM to get the stdio FILE *.
3205 Also, use prototyped definitions, and get rid of the extra
3207 (scm_fptob, scm_pipob): We don't need casts here any more.
3208 * strports.c (prinstpt): Use prototype declarations.
3209 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
3210 and use SCM_STREAM to get the string info. Also, use prototyped
3211 definitions, and get rid of the extra declarations.
3212 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
3215 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
3216 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
3218 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
3219 scm_fgets, for consistency.
3220 (scm_fptop, scm_pipob): References updated.
3222 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
3224 Include the source location in error messages for scripts.
3225 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
3226 stack is still there when we catch the error.
3227 * throw.c (handler_message): If we are handling an error with a
3228 message, then put together the proper arguments and call
3229 scm_display_error, instead of scm_display_error_message. That
3230 displays source location, if it can find it.
3232 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
3234 * gc.c (scm_unprotect_object): Change this so that calls to
3235 scm_protect_object and scm_unprotect_object nest properly.
3236 (scm_protect_object): Doc fixes.
3238 * strings.c (scm_string_set_x): Require the argument to be a
3239 writable string, not a substring or a symbol.
3240 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
3241 (Thanks to John Redford and Charbel Jacquin.)
3243 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
3245 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
3247 * eval.c (safe_setjmp): Remove this misunderstanding.
3248 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
3251 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
3253 * libguile.h: Mark these as C declarations, for compilation by C++
3256 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
3257 __cplusplus clause. I seriously doubt this ever worked the way
3258 the author seems to have intended.
3260 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
3262 Utterly needless cleanups to hopelessly messy code.
3263 * ports.c: Doc fixes.
3264 (scm_fflush): Moved to ...
3265 * genio.c (scm_fflush): ... here, amongst all the other port
3266 method invocation functions.
3267 * genio.h, ports.h: The prototype moves too.
3269 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
3271 * backtrace.c (display_error_body): The current frame does not
3272 always have a parent frame; consider a function called directly
3273 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
3276 * alloca.c (alloca): Undo yesterday's changes, and simply call
3277 malloc directly for storage, and abort if we don't get what we
3278 want. The situation is much simpler --- just call malloc. Emacs
3279 has bizarre/evil requirements (signal handlers might malloc unless
3280 you set this global flag, so you have to set the flag around all
3281 calls to malloc) which we are certainly not going to conform to,
3282 so we can do the simple and obvious thing.
3284 * coop.c (coop_condition_variable_wait): Make this function
3285 static. It's only useful internally --- you should never just
3286 wait on a condition variable.
3287 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
3289 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3291 * unif.c (scm_array_set_x): Accept any kind of number as an
3292 element for a uniform vector of doubles. This is more consistent
3293 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
3295 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
3296 works; I can't conveniently test it myself. (Thanks to Dvid
3297 Tillman for the bug report.)
3299 * init.c: Doc fixes.
3301 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
3302 from here, not from scm_compile_shell_switches (which is a pretty
3303 dumb place to do it).
3304 (scm_load_startup_files): New function.
3305 (scm_ice_9_already_loaded): Variable moved to here from script.c.
3306 * script.c (scm_compile_shell_switches): Don't load the startup
3308 (scm_ice_9_already_loaded): Variable moved.
3309 * init.c (scm_load_startup_files): Prototype for new function.
3310 * gh_init.c (gh_enter): Doc fix.
3312 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3314 Some anti-warning changes from Greg Harvey.
3315 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
3316 warnings when it doesn't understand our NORETURN declarations in
3318 * posix.c (scm_mknod): Similar.
3320 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3322 * posix.c (scm_getpwuid): If we can't find an entry, return our
3323 own message, instead of using scm_syserror --- the getpwMUMBLE
3324 functions don't set `errno' to anything interesting.
3326 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3328 Get rid of warnings from the cooperative threading system.
3329 * threads.h (scm_single_thread_p, scm_yield,
3330 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
3331 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
3332 scm_wait_condition_variable, scm_signal_condition_variable): Add
3333 prototypes for these Scheme-visible functions.
3334 * coop-defs.h (coop_next_runnable_thread,
3335 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
3336 Prototypes for these here, even though they're from iselect.c.
3337 (coop_condition_variable_wait, coop_join): Add prototypes.
3338 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
3339 scm_threads_free_condvar): Make these smob functions static.
3340 * coop-threads.h (coop_init): Give this a real prototype.
3341 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
3342 (coop_next_runnable_thread): No need to provide prototype; it's in
3345 * scmconfig.h.in: .detarenegeR
3347 * iselect.c, threads.c: Doc fixes.
3349 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3351 * Makefile.in: Regenerated with a patched automake, to get
3352 dependency generation right when using EGCS.
3354 * inet_aton.c (inet_aton): Add prototype, to remove compiler
3355 warning. (Thanks to Robert Pluim.)
3357 * inet_aton.c (inet_aton): Reassure the compiler that the
3358 arguments to the <ctype.h> macros are all unsigned characters, not
3361 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3363 Getting rid of more warnings...
3364 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
3365 today's change to ../configure.in.
3366 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
3367 * scmconfig.h.in: Regenertaded.de.,.__
3368 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
3369 (scm_localtime, scm_mktime): Use a const char * to manipulate the
3372 * readline.c: Doc fix.
3373 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
3374 * readline.h (scm_filename_completion_function): Add prototype.
3375 (scm_init_readline): Make this into a prototype.
3377 * readline.c (scm_filename_completion_function): Use SCM_PROC to
3378 declare this, instead of calling scm_make_subr manually.
3380 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
3382 * readline.h (scm_init_readline): Add prototype for this.
3383 (scm_init_readline): Make this a real prototype.
3385 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3387 Warning fixes from Maciej Stachowiak:
3388 * backtrace.h (scm_display_application, scm_backtrace): Add
3390 * debug.c (scm_m_start_stack): Make this function static.
3391 * fluids.h (scm_fluid_p): Add prototype.
3392 * procprop.c (scm_i_procedure_arity): Make this function static.
3393 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3394 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
3395 * root.h (scm_dynamic_root): Add external prototype.
3396 * scmsigs.h (scm_usleep): Add external prototype.
3397 * script.h (scm_init_script): Use prototype, not K&R decl.
3398 * stacks.h (scm_stack_id): Add external prototype.
3399 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3401 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3403 * gh.h: took out the definitions of vset and vref, since they are
3404 replaced by the proper vector routines that correspond to the R4RS
3407 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3409 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3410 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3411 third argument, a C expression that should result in a SCM value,
3412 which is used to initialize the variable. Reimplemented
3413 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3416 * version.h (scm_libguile_config_stamp): Add prototype.
3417 (From Maciej Stachowiak.)
3419 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3421 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3422 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3424 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3426 * print.c (scm_iprin1): Rather than having one i, and using it in
3427 several places, declare a fresh i local to each block where it is
3428 used, and give it a signedness appropriate to its use in each case.
3429 (scm_iprlist): Same.
3431 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3432 comparison warnings.
3434 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3435 signed/unsigned clashes.
3437 * posix.h (scm_tmpnam): Added prototype.
3439 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3440 scm_make_subclass_object): Add external prototypes.
3442 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3443 comparison is okay here.
3445 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3447 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3448 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3450 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3453 * load.c (swap_port): Make this function static.
3455 * load.c (scm_search_path): Make max_path_len and max_ext_len
3456 unsigned, since they're compared against string sizes.
3458 * load.c (init_build_info): Make i unsigned.
3460 * ioext.h (scm_read_line): Add prototype.
3462 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3463 scm_hash_fn_remove_x): Make hash bucket index local variable k
3464 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3465 accurately as possible.
3467 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3468 comparisons, and range checking to make sure those casts are
3471 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3472 signed/unsigned comparisons.
3474 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3475 avoid signed/unsigned comparisons.
3476 * smob.h (scm_numsmob): Change extern declaration to match.
3478 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3479 avoid signed/unsigned comparisons.
3480 * ports.h (scm_numptob): Change extern declaration to match.
3481 (scm_current_load_port, scm_set_port_line_x,
3482 scm_set_port_column_x): New prototypes.
3484 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3485 test code, and it causes warnings.
3487 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3488 gh_uniform_vector_ref): Added prototypes.
3490 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3491 debugging support unconditionally. That's backtrace.c, stack.c,
3492 debug.c, and srcprop.c.
3493 (EXTRA_libguile_la_SOURCES): Omit those from here.
3494 * Makefile.in: Regenerated.
3496 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3498 * options.c (scm_options): Bugfix: Allow empty list of options!
3500 * debug.c, debug.h (scm_single_step): Removed.
3501 (scm_with_traps): New procedure. This procedure could easily be
3502 written in Scheme but needs to be highly optimized.
3504 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3506 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3507 Check SCM_TRAPS_P before trapping.
3509 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3511 Changes to avoid signed/unsigned comparison warnings.
3512 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3513 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3514 so they can have appropriate types for each application. Make i
3515 signed. Use initializers in some spots. I'll probably pay for
3517 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3518 (scm_must_realloc): Make nm unsigned.
3519 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3520 (scm_init_storage): Use prototype-style definition, and make the
3522 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3523 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3525 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3526 avoid signed/unsigned comparison warnings, and because the return
3527 value of readlink may be -1. Don't bother casting the third
3528 argument to readlink.
3530 * filesys.c (scm_dirname, scm_basename): Move these to their own
3531 page, at the end of the file.
3532 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3534 * eval.h (scm_eval_options_interface): Add external prototype for this.
3535 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3537 * eval.c (scm_lookupcar1): Make this static.
3539 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3540 Make these prototype declarations, not K&R-style.
3542 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3543 unsigned comparison warning.
3545 * appinit.c: File removed. It had a single function in it, empty,
3546 whose reason for existence is explained in no documentation or
3547 comment. I think it's there as a default for some Tcl-style
3548 initialization, but Tcl abandoned that approach a while ago.
3549 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3550 (BUILT_SOURCES): Remove appinit.x.
3551 * Makefile.in: Regenerated.
3553 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3555 * Makefile.in: Regenerated using the last public version of
3556 automake, not the hacked Cygnus version.
3558 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3560 Remove Totoro kludge.
3561 * Makefile.in, scmconfig.h.in: Regenerated.
3562 * init.c, readline.c: Don't check if TOTORO is #defined.
3564 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3566 * Makefile.am: Adjust for new thread configuration system.
3567 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3568 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3570 (THREAD_LIBS): Definition deleted; automake will generate such
3571 things automatically.
3572 * Makefile.in: Regenerated.
3574 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3576 Simplify smob and port marking; set the mark bit in the generic
3577 marking code, and make marker routines only responsible for
3578 turning up outgoing pointers.
3579 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3580 before calling the marking function. Don't call the marking
3581 function if it's zero.
3582 * markers.c (scm_mark0): Just return #f. This function isn't
3583 necessary at all now, but it's harmless to call it. We'll leave
3584 it in so other folks' code doesn't croak at link time.
3585 (scm_markcdr): Don't call SCM_SETGC8MARK.
3586 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3587 * dynl.c (mark_dynl_obj): Same.
3588 * root.c (mark_root): Same.
3589 * srcprop.c (marksrcprops): Same.
3590 * unif.c (markra): Same.
3591 * variable.c (scm_markvar): Same.
3592 * ports.c (scm_markstream): Same.
3593 (void_port_ptob): Specify zero for our marking function.
3594 * debug.c (debugobjsmob): Same.
3595 * dynwind.c (guardsmob): Same.
3596 * filesys.c (dir_smob): Same.
3597 * fluids.c (fluid_smob): Same.
3598 * fports.c (scm_fptob, scm_pipob): Same.
3599 * mallocs.c (mallocsmob): Same.
3600 * regex-posix.c (regex_t_smob): Same.
3601 * smob.c (freecell, flob, bigob): Same.
3602 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3603 * throw.c (jbsmob, lazy_catch_funs): Same.
3605 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3607 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3608 scm_copy_tree on code in order not to let memoized code to leak
3609 out. Thus, scm_copy_tree needs to copy vectors as well since
3610 quasiquote can introduce evaluated code also inside vector
3613 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3615 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3617 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3618 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3621 * unif.c: Say that ivect and uvect are of type signed and unsigned
3622 long instead of int in commentary so that it correctly describes
3625 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3627 * stime.c: Removed declaration of strptime. (It should be
3628 declared by the system headers. If it turns out that some systems
3629 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3631 * stime.h: Renamed TIMEH --> STIMEH
3633 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3634 to increase portability, don't use structure assignment.
3635 (Thanks to Nicolas Neuss.)
3637 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3639 (finalize_fd_sets): Added empty statement after last case label.
3640 (Thanks to Nicolas Neuss.)
3642 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3645 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3647 * init.c, readline.c: OK, I won't have these readline.x bug
3648 reports anymore. We've had them since April. The current reason
3649 is a completely unintelligible failure of totoro.red-bean.com to
3650 do the test for rl_getc_function in libreadline correctly. This
3651 kludge overrides the test if we're on totoro so that the snapshot
3652 generation process can work.
3654 * readline.c: Define a strdup replacement if not existent on system.
3656 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3658 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3659 This change makes scm_make_vector R5RS compatible. We cannot keep
3660 the third argument since people want to be able to deduce the form
3661 of the C function call only by looking at R5RS. (At the same time
3662 we have removed some unnecessary complexity!)
3664 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3665 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3666 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3667 argument in call to scm_make_vector.
3669 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3671 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3672 This macro is useful in applications.
3674 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3676 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3677 (scm_parse_path, scm_search_path): New Scheme level procedures.
3679 * load.h (scm_internal_parse_path, scm_parse_path,
3680 scm_search_path): Declared.
3682 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3684 * filesys.c (dirname, basename): New procedures.
3686 * init.c (scm_boot_guile_1): Removed condition around
3689 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3690 new data type (guards) for representation of C level guards and
3691 data on the wind chain.
3692 (scm_internal_dynamic_wind): New function.
3694 * dynwind.h: Declare scm_internal_dynamic_wind.
3696 * root.h (scm_root_state): Added scm_cur_loadp.
3698 * root.c (mark_root): Added comment about cur_loadp.
3700 * load.c: #include "dynwind.h";
3701 (scm_primitive_load): Use scm_inner_dynamic_wind to update
3704 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3706 * ports.c (current-load-port): New procedure.
3708 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3710 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3711 not a tty, return #f.
3713 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3714 to Julian Satchell and Roland Kaufmann.)
3716 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3717 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3719 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3721 * debug.h, debug.c (scm_start_stack): New function. Implements
3722 the guts of old scm_m_start_stack.
3724 * debug.c (scm_m_start_stack): Use scm_start_stack.
3726 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3727 start_stack and restart_stack. (These have static scope.)
3729 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3731 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3732 readline functions to come in release 2.3. (Thanks to Chet
3734 (handle_errors): Use the above functions.
3736 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3738 * readline.c: Improvements for readline support: Handle errors
3739 better; Implement before-read-hook.
3741 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3743 * init.c (scm_boot_guile_1), readline.c: Test for
3744 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3745 assure that we have version >= 2.1.)
3747 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3749 * readline.c (scm_readline): Defer interrupts while we're calling
3752 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3753 away the string to add_history.
3754 (completion_function): Do completion for readline. (Thanks to
3756 (scm_filename_completion_function): New procedure: Filename
3758 (current_input_getc): New function. Use this one instead of
3759 standard getc from readline.
3761 * throw.c, throw.h (scm_handle_by_throw): New function: This
3762 handler throws errors to next handler on the dynwind chain.
3764 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3766 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3769 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3771 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3773 (scm_procedure_properties): Modified to return arity together with
3775 (scm_procedure_property): Added the read-only property `arity'.
3776 (scm_set_procedure_property_x): It is an error to set the `arity'
3779 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3780 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3782 * procprop.h (scm_sym_arity): New symbol.
3784 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3785 to set the dispatch procedure of an operator or entity object.
3787 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3788 Made procedure slots read-only.
3790 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3791 scm_tcs_cons_gloc case in zero args switch; Fixed args
3792 construction for operators in scm_tcs_cons_gloc case in two args
3795 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3797 * fluids.c: Removed use of assert.h (in order to avoid
3800 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3802 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3804 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3805 change makes the evaluator safer at the cost of evaluation speed.
3806 It handles the case when the user has added a non-immediate
3807 improper end of the application form, e.g., `(+ 0 . x)'.
3808 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3809 minimize the extra cost as much as possible. The new code is
3810 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3811 problem with structs planted directly in the code (e.g. by a
3812 macro). This no longer causes segmentation fault. (Thanks to
3815 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3816 arg `proc' in order to be able to throw errors; New argument
3819 * Removed extra #include "debug.h"
3821 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3823 * scmsigs.c: Declare usleep as returning void on some systems.
3824 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3827 * coop.c (usleep): Return void on some systems.
3829 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3831 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3833 * coop.c: Changed return type of usleep to int.
3835 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3836 isn't found in the OS.
3838 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3839 isn't enabled. (Thought that I had made this change ages ago...)
3841 * iselect.c: Declare bzero if not defined by OS.
3843 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3845 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3846 condition. (Thanks to John Tobey.)
3848 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3849 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3852 * __scm.h: Start the long-term project of moving to POSIX threads.
3853 Phase 1: Classification of all critical sections.
3854 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3855 for A sections. (See comments in __scm.h for details.)
3857 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3858 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3860 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3862 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3863 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3864 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3865 dependencies on $(srcdir)/Makefile.in
3866 $(top_builddir)/config.status in order to avoid circularity.
3868 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3869 from argc if argc was 0 initially.
3871 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3872 in generation of libpath.h.
3874 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3876 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3877 libguile from 2 to 3.
3879 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3881 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3883 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3885 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3886 scm_set_port_column_x, scm_port_filename,
3887 scm_set_port_filename_x): Removed optional arguments. Added
3888 proper argument checking.
3890 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3891 stack size in machine words.
3893 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3894 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3895 to Ole Myren Röhne.)
3897 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3899 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3900 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3902 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3905 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3906 procedure apply: Copy argument lists before pushing them unto the
3907 environment so that the environment won't get mutated due to
3908 manipulation of procedure arguments. This should perhaps be
3909 regarded as a temporary solution until someone finds a more
3910 efficient one. (Thanks to Maciej Stachowiak.)
3912 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3914 * script.c (scm_compile_shell_switches): Use "guile" as default
3915 zero arg if argc is NULL.
3917 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3919 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3920 is zero. (Thanks to Dirk Herrmann.)
3922 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3924 * ports.c (scm_add_to_port_table): First line is now line 0
3925 (was 1). (Interface changed according to suggestion by Per
3928 * backtrace.c (display_header): Add 1 to line and column numbers
3929 when presenting them to the user.
3931 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3932 from debug.c --> eval.c
3934 * eval.h, eval.c (scm_eval_options_interface): New options
3936 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3937 i.e. stacks for new threads.
3939 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3941 * eval.c (unsafe_setjmp): Removed with #if 0.
3943 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3946 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3947 to avoid compiler warnings.
3949 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3951 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3953 * throw.c (handler_message): Print message on current error port
3954 instead of default error port. (Thanks to Maciej Stachowiak.)
3956 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3958 * ports.c (scm_add_to_port_table): allocate in units of
3959 struct scm_port_table *, not struct scm_port_table.
3960 * posix.c (scm_close_pipe): remove the port from the port table
3962 Thanks to Rob Engle for both fixes.
3964 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3966 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3967 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3969 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3971 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3973 * backtrace.c (display_error_body, display_backtrace_body),
3974 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3975 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3976 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3977 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3980 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3981 don't receive the jmpbuf arg anylonger.
3982 (scm_catch): Don't accept a #f tag.
3983 (scm_throw): Check that key is a symbol.
3984 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3986 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3988 * async.c (async_pending): Removed declaration.
3990 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3992 * dynwind.c (scm_wind_chain): New debug function.
3994 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3995 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3996 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3997 extra layer of functions around the body and handler of a thread.
3998 This extra layer makes sure that the handler is called in the
3999 dynamic context of the surround (= empty dynwind list), but under
4000 the *dynamic root* of the body. We can not use the dynamic root
4001 of the surround since that root belongs to another thread => stack
4002 is not handled correctly. It may seem ugly to use this extra
4003 layer, but the extra cost in terms of execution time is really
4004 negligible compared to the total amount of time required to create
4005 a thread, and it would reduce maintainability to duplicate the
4006 crucial and complicated steps performed by cwdr.
4008 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
4009 (SCM_ALLOW_INTS): Added thread switching code before interrupts
4010 get re-enabled. The important effect of this is that interrupts
4011 are blocked during thread switching so that thread data structures
4012 don't risk getting messed up by an unfortunate signal.
4013 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
4014 seems to do more aggressive optimization which actually move
4015 instructions around in these macros in a fatal way. Therefore:
4016 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
4017 just superstitious...)
4018 (SCM_TICK): Maybe do a context switch and take care of asyncs.
4019 This macro should be used instead of SCM_ASYNC_TICK since the
4020 latter doesn't do context switches any more.
4022 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
4023 instead of SCM_ASYNC_TICK.
4025 * coop.c, iselect.c: Since thread switches are now performed with
4026 interrupts masked, we can't use the old mechanism of delivering
4027 signals immediately when they arrive. Signals must instead be
4028 delivered when the asyncs run *after* the end of the critical
4029 section in scm_internal_select. But this also means after context
4030 switch so that the signal will be delivered to a different thread.
4031 To avoid this, I have changed the protocol of
4032 coop_wait_for_runnable_thread and friends so that they are allowed
4033 to return the original thread. So, if a signal arrives during
4034 scm_internal_select, we won't any longer be forced do a context
4035 switch, but can remain in the same thread and deliver the signal
4038 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
4039 scm_asyncs_pending and made it global.
4041 * iselect.c: Small fixes.
4043 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
4044 coop_condition_variable_init, coop_condition_variable_wait,
4045 coop_condition_variable_signal): Changed return type from `void'
4046 to `int'. This is to adhere closer to the pthreads interface.
4047 This, in turn, is part of an attempt to provide C versions of the
4048 mutex and condition variable primitives which can be part of a
4049 frontend to COOP or pthreads.
4051 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
4052 coop_condition_variable_destroy): New functions.
4054 * coop-threads.c (scm_wait_condition_variable): Use
4055 coop_condition_variable_wait_mutex.
4057 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
4058 Definitions moved to coop-defs.h.
4060 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
4061 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
4062 scm_cond_destroy): New C interface to mutecis and cond vars.
4064 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4066 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
4068 * iselect.c: Now several threads can wait on the same file
4069 descriptor. The behaviour is compatible with OS select: All
4070 threads waiting for the fd return with the same status.
4072 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4074 * coop-threads.c, threads.h (scm_spawn_thread): New function.
4075 Can spawn a thread from application C code.
4077 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4079 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
4080 gh_doubles2scm): New functions.
4082 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
4084 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
4085 commented-out version of gh_eval_str()
4087 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
4089 * socket.c (scm_bind): free soka after use.
4091 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
4093 * stime.c (tzvar): new variable.
4094 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
4095 avoid memory leaks when allocating.
4097 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
4099 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
4102 * gc.c, tags.h: Doc fixes.
4104 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4106 * eval.c (macro-eval!): Removed. This function was a design bug.
4107 It allowed memoized code to leak out to the scheme level. Most
4108 things that you could do with `macro-eval!' can be done with
4111 1997-12-20 Tim Pierce <twp@skepsis.com>
4113 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
4114 scm_fgets now depends on ftell(3) to know how many bytes were
4117 1997-12-15 Tim Pierce <twp@skepsis.com>
4119 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
4120 dealing with strings.
4122 1997-12-13 Tim Pierce <twp@skepsis.com>
4124 Make %read-line more suitable for implementing read-line efficiently.
4125 * ioext.c (scm_read_line): Strip the terminating newline from a
4126 string, and return a cons of the string and its terminator.
4128 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
4129 of the string that is read is stored in this memory location.
4130 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
4131 * genio.c, genio.h (scm_do_read_line): Update caller.
4132 * ports.h (scm_ptobfuns): Update typedef.
4133 * fports.c (scm_fptob, scm_pipob): Update struct.
4135 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4137 * filesys.c (set_element): Return file descriptor.
4138 (fill_select_type): Return the highest file descriptor.
4139 (scm_select): Tell select about the highest file descriptor. On
4140 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
4141 Therefore the extra overhead for calculating the maximum fd seems
4142 to be more than compensated. Is this correct? In any case,
4143 scm_internal_select will be much faster with this info.
4144 (scm_select, fill_select_type, set_element): Don't accept any kind
4145 of object in the file descriptor list or vector.
4147 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4149 * iselect.c (finalize_fd_sets): Bugfix.
4151 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4153 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
4154 when using scm_internal_select (since we might switch to another
4157 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
4159 * simpos.c (scm_system): always define: use sysmissing if not
4160 available. Check for HAVE_SYSTEM instead of _Windows (does
4161 Windows lack system or does it have an unusable one?).
4162 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
4163 Let the argument be optional: if not supplied, call system(NULL).
4165 * ports.c (scm_close_port): relax the type check from OPPORTP to
4166 PORTP; closing a closed port is allowed.
4168 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
4170 * fports.c (scm_fgets): Return if the last char in a chunk is
4171 newline. When fgets returns a string whose length is `size-1', it
4172 is ambiguous whether a whole line was retrieved, so we must check
4173 explicitly whether a line terminator is present.
4175 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4177 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
4178 before taking the CDR. (Thanks to Harald Meland.)
4180 * filesys.c (scm_stat): Slightly optimized.
4182 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
4184 * ports.c (scm_close_port): Make sure the port is open before
4187 * guile-snarf.in: Pass args through to gcc in a way that preserves
4188 whitespace boundaries. (Thanks to Greg Badros.)
4190 1997-12-02 Tim Pierce <twp@skepsis.com>
4192 * stacks.c (scm_frame_procedure): Reverse the logic in the return
4193 statement. (Thanks to Doug Evans for pointing this out.)
4195 1997-12-01 Tim Pierce <twp@skepsis.com>
4197 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
4199 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
4201 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
4202 errno macro expansion of this field name. (errno is a C
4203 preprocessor macro on some systems.)
4205 1997-11-29 Tim Pierce <twp@skepsis.com>
4207 * iselect.c: Doc fix.
4209 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
4211 * init.c (scm_start_stack): Removed initialization of
4212 scm_the_last_stack_var.
4214 * backtrace.h: Declare scm_the_last_stack_var.
4216 * backtrace.c: Define scm_the_last_stack_var.
4218 * root.c (mark_root): Don't mark the_last_stack_var.
4220 * root.h (scm_root_state): Removed the_last_stack_var.
4222 * throw.c: Added #include "fluids.h"
4223 (ss_handler): `the-last-stack' is now a fluid.
4225 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
4226 --> the_last_stack_fluid.
4228 * backtrace.c: Added #include "fluids.h"
4229 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
4230 (scm_backtrace): `the-last-stack' is now a fluid.
4232 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
4233 after scm_init_fluids.
4235 1997-11-28 Tim Pierce <twp@skepsis.com>
4237 * iselect.c: #ifdef USE_THREADS around thread-related includes.
4239 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
4240 DLSYM_ADDS_USCORE to decide whether to add an underscore.
4242 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4244 * iselect.c (coop_next_runnable_thread,
4245 coop_wait_for_runnable_thread): Disable interrupts so that no
4246 async is executed before a potential error_revive.
4247 (scm_internal_select): Disable interrupts during the parts of the
4248 code which manipulate the sleep queue and the file descriptors.
4250 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4252 * Makefile.am: Added iselect.c and iselect.h.
4254 * coop.c (coop_qinit): Initialize fields used by
4255 scm_internal_select.
4256 (coop_qget, coop_qget, coop_tmp_queue): Made global.
4257 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
4258 replacement in iselect.c.
4259 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
4260 coop_join): If GUILE_ISELECT enabled, use
4261 coop_wait_for_runnable_thread instead of
4262 coop_next_runnable_thread.
4263 (usleep, sleep): New replacements for system functions if
4264 GUILE_ISELECT is enabled.
4266 * coop-threads.h: Declare coop_wait_for_runnable_thread.
4268 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
4270 * filesys.c: Added #include "iselect.h". Moved FD-macros to
4271 iselect.h. Implement Scheme level `select' using
4272 scm_internal_select. (See NEWS.)
4274 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
4276 * init.c: Call scm_init_iselect.
4278 * iselect.h, iselect.c: New files. Implements
4279 scm_internal_select. (See NEWS.)
4281 1997-11-27 Tim Pierce <twp@skepsis.com>
4283 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
4284 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
4285 and scm_must_free, since ultimately the string returned will be copied
4286 by scm_makfrom0str anyway. Also, read any characters that may have
4287 been pushed onto the port with scm_ungetc.
4288 * ports.c (scm_generic_fgets): Same as for scm_fgets.
4289 * ioext.c (scm_read_line): Free string after Guilifying it.
4290 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
4292 1997-11-26 Anthony Green <green@hoser.cygnus.com>
4294 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
4296 * gh.h: Safely wrap prototypes for c++ usage.
4298 1997-11-25 Mark Galassi <rosalia@cygnus.com>
4300 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
4301 gh_repl (argc, argv).
4303 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
4305 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
4306 and to invoke scm_shell().
4307 (gh_launch_pad): took out the loading of boot-9.scm from here,
4308 since it is probably best to let the user control that. In fact,
4309 gh_repl() now invokes scm_shell() which does that.
4311 1997-11-23 Mark Galassi <rosalia@cygnus.com>
4313 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
4316 1997-11-22 Tim Pierce <twp@twp.tezcat.com>

4319 yesterday's underscore patch. (Thanks to Marius Vollmer for
4322 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
4324 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
4325 DLSYM_ADDS_USCORE is not defined.
4327 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
4329 * gh_data.c (gh_uniform_vector_length):
4330 (gh_uniform_vector_ref): started implementing the uniform types in
4333 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
4335 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
4336 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
4338 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
4340 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
4341 configure.in was changed).
4343 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
4345 * Makefile.am (modinclude_HEADERS): Include readline.h here.
4346 * Makefile.in: Regenerated.
4348 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
4350 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
4351 OPORT is an `open' port, not an output port.
4353 * filesys.c (scm_close, set_element, get_element, scm_chown,
4354 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
4355 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
4356 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
4357 scm_close_port, scm_port_line, scm_set_port_line_x,
4358 scm_port_column, scm_set_port_column_x, scm_port_filename,
4359 scm_set_port_filename_x, scm_port_mode,
4360 scm_close_all_ports_except, scm_set_current_output_port,
4361 scm_set_current_error_port): Likewise
4362 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
4363 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
4365 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
4366 * backtrace.c (display_backtrace_body): Likewise
4367 * fports (scm_setvbuf): Likewise
4368 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
4369 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
4370 scm_getpeername, scm_send, scm_sendto): Likewise
4371 * unif.c (scm_uniform_array_write): Likewise
4373 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
4375 Minor problems with substring-related tag changes.
4376 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
4377 exactly what we want to leave in to detect substrings.
4378 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
4379 * tags.h: Fix diagrams and comments describing the S tag bit;
4380 remove vestigial remarks about the D tag bit.
4381 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
4382 * strings.c: Formatting tweaks.
4384 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
4385 variable first; then SCHEME_LOAD_PATH, with a warning message.
4386 (scm_parse_path): New function.
4387 * script.c: Doc fixes.
4389 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
4391 Readline support, from Daniel Risacher.
4392 * readline.c, readline.h: New files.
4393 * init.c: #include "readline.h".
4394 (scm_boot_guile_1): Call scm_init_readline, if we have it.
4395 * Makefile.am (libguile_la_SOURCES): Include readline.c.
4396 * Makefile.in: Regenerated.
4397 * scmconfig.h.in: Regenerated, after change to ../configure.
4399 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4401 * gh.h: gh_vector_set -> gh_vector_set_x
4403 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4405 * gh_data.c (gh_vector_set_x): changed name to make it consistent
4406 with the ! -> _x mapping when going from Scheme to C.
4408 1997-10-19 Mark Galassi <rosalia@cygnus.com>
4410 * gh.h (gh_reverse):
4418 (gh_assoc): added these gh_ functions implemented as macros.

4421 (gh_string_equal_p): added these two missing predicates.
4423 * gh_list.c (gh_append):
4428 (gh_set_cdr_x): added these routines as I go through and try to
4429 complete the picture R4RS functions that should be mirrored in the
4432 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4434 * tags.h (scm_tc7_substring): Changed the comment and code to
4435 conform with the changes below. Folks! We have suddenly two new
4436 free tc7 codes!!! Jummy, jummy!
4438 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
4440 * Makefile.in: Rebuilt.
4441 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
4443 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
4444 * unif.c (scm_vector_set_length_x): Don't handle multibyte

4459 * tags.h (SCM_TYP7SD): Removed.
4460 (SCM_TYP7D): Removed.
4461 (scm_tc7_mb_string): Removed.
4462 (scm_tc7_mb_substring): Removed.

4465 Don't include "mbstrings.h".
4466 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
4467 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
4469 Don't include "mbstrings.h".
4470 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
4471 (SCM_SYMBOL_SLOTS): Define as 4.
4472 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.

4493 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
4494 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
4496 1997-10-12 Mark Galassi <rosalia@cygnus.com>
4498 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
4500 * gh_test_c.c (c_vector_test): some improvements on the vector
4503 * gh.h (gh_vector): this used to exist but do the wrong thing.
4504 Now it (almost) does the right thing, though it takes a list
4505 instead of the individual arguments. I need to see how it could
4507 (gh_list_to_vector): added this function as a macro. Corresponds
4508 to Scheme's (list->vector ...).
4509 (gh_vector_to_list): added this function as a macro. Corresponds
4510 to Scheme's (vector->list ...).
4512 * gh_data.c (gh_vector_ref): renamed from gh_vref to
4513 gh_vector_ref, so that it resembles the Scheme routines more.
4514 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
4515 resembles the Scheme routines more.
4516 (gh_make_vector): this used to be (stupidly) called gh_vector().
4517 This is the right name, since it does the same thing as the Scheme
4518 (make-vector ...) procedure.
4520 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4522 * ports.h: #include "libguile/print.h"
4524 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
4525 Some indentation fixes.
4527 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
4528 longer a user field; New field: class_flags.
4530 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
4532 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>

4535 gh_int2scmb(), which is now tagged as obsolete.
4537 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4539 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4540 macros should by convention not test for NIMPness.)
4541 (SCM_COERCE_OPORT): Adjust indentation.
4543 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4544 SCM_NIMP test before SCM_PRINT_STATE_P.

4547 scm_struct_i_layout --> scm_vtable_index_layout
4548 scm_struct_i_vcell --> scm_vtable_index_vcell
4549 scm_struct_i_vtable --> scm_vtable_index_vtable
4550 scm_struct_i_printer --> scm_vtable_index_printer
4551 scm_struct_i_vtable_offset --> scm_vtable_offset_user
4553 * struct.c (scm_print_struct): Use new printer slot; Default
4554 printing: Also output hex code of vtable so that type identity
4555 will be indicated as well.
4556 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4557 Removed struct_printer_var; Removed struct-vtable-offset;
4558 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4559 vtable-offset-user): New constants.
4561 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
4562 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
4563 If this slot contains a procedure, use that to print structures of
4564 the type represented by this vtable.
4566 * print.c (scm_iprin1): Don't print arguments of macro
4567 transformers. (They are always: exp env.); Bugfix: Unmemoize
4568 transformer source with correct environment.
4570 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4572 Streamlining of call-with-dynamic-root:
4574 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
4575 there is now only one catch.
4576 (cwdr_outer_body): Removed.
4577 (cwdr_handler): New function.
4578 (scm_internal_cwdr): New function to perform the function of cwdr
4579 but take args that are more useful to C code. Also, the handler
4580 is now invoked *outside* of the new dynamic root, like the docs
4581 say. We no longer have to catch absolutely all errors, the caller
4582 is responsible for using a handler that does not throw, if he
4584 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4585 * root.h (scm_internal_cwdr): New prototype.
4587 Even more but risky streamlining:
4589 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4590 allocation of the jumpbuf of a root continuation. The changes
4591 below are controlled by it. They are now deactivated.
4592 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4593 the JMPBUF of the scm_rootcont to NULL before returning.
4595 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4596 when they are non-NULL.
4597 (scm_gc_mark): Likewise, mark only when non-NULL.
4599 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4600 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4602 * gc.c (scm_done_malloc): New function.
4603 gc.h (scm_done_malloc): New prototype.
4605 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
4606 (struct scm_print_state) [revealed]: New field.
4607 (scm_print_state_vtable): Make visible to the outside world for
4608 type checking purposes.
4609 (scm_valid_oport_value_p): New prototype.
4611 * print.c (scm_valid_oport_value_p): New function to check whether
4612 a certain value is acceptable as a port argument.
4613 (scm_print_state_vtable): New variable.
4614 (scm_free_print_state): Set `revealed' field to false.
4615 (scm_iprin1): Call user supplied closure printer with
4616 scm_printer_apply. Print in the traditional way when there isn't
4617 one or when it returns #f.
4618 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4619 Accept a port/print-state pair in addition to just a port.
4620 (scm_prin1): Don't return the print_state to the pool when it has
4622 (scm_printer_apply): Set `revealed' field of print_state to true.
4623 (scm_init_print): Set scm_print_state_vtable.
4624 (print_state_fluid, print_state_fluid_num): Removed.
4626 * throw.h (scm_handle_by_proc_catching_all): New prototype
4627 throw.c (scm_handle_by_proc_catching_all): New function
4629 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4631 * Makefile.in: Regenerated with automake 1.2c.
4633 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4635 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4636 was looping endlessly.
4638 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4640 * strports.c (scm_eval_string): Don't close the port.
4642 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4643 former returns a nice normal integer. (Thanks to Daniel
4646 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4648 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4649 makefile variable as a build parameter called LIBS. The
4650 build-guile program will use this, for the time being.
4651 * Makefile.in: Regenerated.
4653 Thanks to Shiro Kawai:
4654 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4655 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4658 * Makefile.in: Regenerated with automake 1.2a.
4660 * script.c (scm_compile_shell_switches): If we hit the -c or --
4661 arguments, don't set the car of (command-line) to scm_usage_name,
4662 the prettified name of the guile executable; give it the full
4663 path, the way shells usually handle $0.
4665 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4667 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4668 Scheme-level name `array-map' and renamed `serial-array-map' to
4669 `serial-array-map!'.
4671 * backtrace.c: Introduced exception handlers which now enclose
4672 `display-error' and `display-backtrace' so that error reporting
4673 won't get into infinite loops if an error occurs during displaying
4674 of the error. This can very easily happen with user supplied
4675 print call-back routines.
4677 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4679 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4680 the names `serial-array-map' and `array-map' should be removed.)
4682 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4684 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4685 Added #include "objects.h"
4687 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4688 Add #include "feature.h".
4690 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4691 (modinclude_HEADERS): Added objects.h.
4693 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4694 This test is needed at many places in the code and should be
4695 abstracted. (Motivated by the need of this test in libguiletk.)
4697 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4698 (scm_eval_string), load.c (scm_primitive_load,
4699 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4700 Use SCM_EOF_OBJECT_P.
4702 * eval.c (scm_init_eval): Add feature `delay'.
4704 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4706 * scmhob.h: Removed.
4708 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4710 * list.h (SCM_LISTn): New macros. Make list creation in C code
4711 prettier. The idea comes from STk.
4713 * sequences.h, sequences.c, append.h, append.c: Removed. These
4714 files implemented non-R4RS operations which would encourage
4715 non-portable programming style and less easy-to-read code.
4717 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4720 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4721 sequences.h, #include append.h.
4723 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4726 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4728 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4730 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4732 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4734 * eval.c: Added #include "objects.h"
4736 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4739 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4740 adjacent smob numbers.
4742 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4744 * procprop.h: Added declaration of scm_i_inner_name.
4746 * gsubr.c: New global symbol scm_i_inner_name.
4748 * debug.c (scm_procedure_name): Try procedure property
4749 `inner-name' if `name' fails.
4751 * print.c (scm_iprin1): Use scm_macro_name.
4753 * eval.c (scm_m_define): Give names to macros as well; Only the
4754 first top-level definition gives a procedure/macro a name.
4755 Otherwise confusing names can turn up in backtraces.
4756 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4757 `name'; Give names to macros as well.
4759 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4760 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4763 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4765 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4767 (prinmacro): Removed. The code has been moved/merged into print.c
4768 in order to decrease code redundancy. We want macros to print in
4769 a way equivalent to procedures, and it would be silly to duplicate
4770 the required code. (We don't want to maintain two places.)
4771 (macrosmob): Print field is now a NULL pointer.
4773 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4774 scm_macro_transformer): New prototypes.
4775 (scm_tc16_macro): Declared.
4777 * print.c (scm_iprin1): Added code for printing of macros. Macros
4778 are now printed in a way equivalent to procedures.
4780 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4782 * procs.h (scm_closure_p): Added declaration.
4784 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4786 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4787 Shouldn't pass "heap" as the subr name.
4789 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4791 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4792 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4793 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4794 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4795 SCM_BOOL_T. Any non-false value is true.
4797 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4799 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4800 scm_gensym): Added prototypes.
4802 * symbols.c (scm_gensym): New function. This will speed up
4803 certain types of applications (such as macro systems) which
4804 generate lots of symbols.
4806 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4808 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4810 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4812 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4813 specifier, since (2) or (2 . 3) would cause SEGV.
4814 (scm_transpose_array): more argument checking fixes.
4816 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4818 * Makefile.in: Regenerated.
4820 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4822 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4824 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4826 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4828 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4830 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4831 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4834 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4835 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4836 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4837 scm_array_p, scm_array_rank, scm_array_dimensions,
4838 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4839 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4840 scm_array_prototype): Added case scm_tc7_wvect.
4842 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4844 * errno.h: prototype for scm_strerror.
4845 * error.c (scm_strerror): new procedure.
4847 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4849 * list.c (scm_list_append_x): Allow non-pair as last argument.
4850 This is consistent with the R4RS append and is probably the
4851 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4853 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4855 * stime.h: prototype for scm_times.
4856 * stime.c (scm_times): new procedure.
4857 * ioext.c (scm_fseek): if the first argument is a file descriptor
4859 (scm_ftell): if the first argument is a file descriptor call lseek
4861 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
4862 * filesys.c (scm_chmod): if the first argument is a file descriptor,
4864 (scm_chown): if the first argument is a port or file descriptor,
4866 (scm_truncate_file): new procedure.
4867 Add DEFER/ALLOW INTS to a few other procedures.
4868 (scm_fsync): new procedure.
4869 (scm_open_fdes): new procedure.
4870 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
4872 (scm_fcntl): the first argument can now be a file descriptor. The
4873 third argument is now optional.
4875 * posix.c (scm_execl, scm_execlp): make the filename argument
4876 compulsory, since omitting it causes SEGV.
4877 (scm_sync): return unspecified instead of #f.
4878 (scm_execle): new procedure.
4879 (environ_list_to_c): new procedure.
4880 (scm_environ): use environ_list_to_c. disable interrupts.
4881 (scm_convert_exec_args): take pos and subr arguments and
4882 improve error checking.
4884 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4886 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4887 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4888 argument to SCM_ASSERT. Furthermore, the name of the function
4889 should be passed as first argument when signalling
4890 SCM_WNA. (Thanks to Thomas Morgan)
4892 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4893 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4894 dispatches on the number of actual args has a default case
4895 reporting an internal error. This is a vestige from a version
4896 that mallocated a SCM vector to hold the arguments. In the
4897 current version this check is too late: if it ever happens we will
4898 have already overstepped the bounds of the array.
4900 Also, the patch [...] adds a check for too many actual arguments."
4902 mdj: Removed check for "internal programming error".
4904 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4906 * gh_io.c (gh_write): New function.
4908 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
4909 throw.c (scm_internal_stack_catch): New sibling to the other catch
4910 functions. Code moved from gh_eval.c.
4911 throw.h: Added header.
4912 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
4913 scm_internal_stack_catch.
4915 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4917 * ioext.h: fix up prototypes.
4918 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
4919 Scheme name is now dup->fdes.
4920 (scm_dup_to_fdes): make the second argument optional and
4921 fold in the functionality of scm_primitive_dup.
4922 (scm_primitive_dup): deleted.
4924 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4926 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
4927 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4928 ultrix are defined. Use setvbuf instead of setbuf.
4929 (scm_setvbuf): new procedure.
4930 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
4931 (scm_setfileno): moved from ioext.c.
4932 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
4933 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.

4942 * print.c (scm_iprin1): Enter printed structures into the print
4943 state as nested data while they are printed.
4944 (print_state_fluid, print_state_fluid_num): New variables.
4945 (scm_init_print): Initialize them.
4946 (scm_iprin): If print_state_fluid carries a print_state, use that
4947 instead of creating a new one.
4948 (scm_printer_apply, apply_stub, struct apply_data): New
4949 definitions to help with calling printer functions written in
4951 * print.h (scm_printer_apply): New prototype.
4953 * struct.c (scm_print_struct): Use scm_printer_apply to call the
4954 user defined struct printer.

4962 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
4964 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
4965 SCM_ASSERT: arg comes before pos.
4967 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4969 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
4970 to a list of length zero correctly.
4972 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4974 Supply an `fgets' method for port objects to do fast line i/o.

4988 * ioext.h: removed scm_duplicate_port prototype.
4990 * ioext.c (scm_primitive_dup2): return the new file descriptor
4991 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
4993 (scm_fdopen): bug fix: don't try to make port unbuffered until its
4994 stream has been set.
4995 (scm_duplicate_port): deleted, there's now an implementation in
4997 (scm_primitive_dup2): do nothing if newfd == oldfd.
4999 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
5001 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
5004 * ioext.h: new prototypes.
5005 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
5007 * fluids.c (next_fluid_num): don't do
5008 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
5010 * ports.h: prototypes too.
5011 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
5013 * fports.h: prototype too.
5014 * fports.c (scm_evict_ports): moved from ioext.c.
5016 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5018 * ports.c (scm_close_port): return a boolean instead of unspecified.
5019 throw an error if an error other than EBADF occurs.
5021 * filesys.h: scm_close prototype.
5022 * filesys.c (scm_close): new procedure, can close file descriptors
5023 and ports (scsh compatible).
5025 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
5028 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
5030 * fluids.c, fluid.h: New files.
5031 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
5032 (modinclude_HEADERS): Added "fluids.h"
5034 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
5035 scm_init_fluids to initialize the fluid machine.
5036 (scm_start_stack): Initialize the fluids of the first root with
5037 scm_make_initial_fluids.
5039 * root.h: Added "fluids" member to scm_root_state.
5040 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
5041 (scm_make_root): Call scm_copy_fluids to make fluid bindings
5042 unique for the new root when it has a parent.
5044 * smob.h: Include "libguile/print.h" to make scm_print_state
5047 * dynl.c (free_dynl_obj): New function to free the dynamic object
5048 data. (dynl_smob): Use it.
5049 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
5050 the dynamic object data below the linking of the object to avoid
5051 memory leak when the linking code throws an error. Now the code
5052 leaks a whole dynamically linked library when must_malloc throws,
5053 but that should be much less likely.
5055 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
5057 Changes to compile under gnu-win32, from Marcus Daniels:
5058 * stime.c (tzset): If tzset isn't provided, make it a NOP.
5059 (scm_localtime): Change SCM_EOF to SCM_EOL.
5060 (scm_mktime): Likewise.
5061 * socket.c: Don't include sys/un.h unless autoconf tells
5062 us Unix domain sockets are available.
5063 (scm_fill_sockaddr): Ignore Unix domain code.
5064 (scm_addr_vector): Likewise.
5065 (scm_init_addr_buffer): Likewise.
5066 (scm_socketpair): Don't include unless socketpair was
5067 found during autoconf.
5068 * simpos.c (SYSTNAME): Treat cygwin like Unix.
5069 * scmsigs.c (scm_pause): Don't include unless pause was found
5071 * posix.c (scm_getgroups): Don't include unless support function
5072 was found during autoconf (in this case, getgroups).
5073 (scm_setpwent): For setpwent.
5074 (scm_setegid): For setegid.
5075 * net_db.c (scm_inet_netof): Don't include unless support
5076 function was found during autoconf (in this case, inet_netof).
5077 (scm_lnaof): For inet_lnaof.
5078 (scm_inet_makeaddr): For inet_makeaddr.
5079 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.

5090 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
5091 scm_misc_error, not SCM_EOF.
5093 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
5094 arguments for formatting the error message, not SCM_BOOL_F. I
5095 think this is left over from the (eq? '() #f) days.
5097 * read.c (recsexpr): Give this a dummy definition if
5098 DEBUG_EXTENSIONS isn't #defined.
5100 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
5102 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
5105 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
5107 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
5110 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
5112 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
5113 alloca.lo will be included in @LIBLOBJS@. Something better than
5114 this should be possible.
5115 * Makefile.in: Regenerated.
5117 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
5119 * simpos.h: prototype for scm_primitive_exit.
5120 * simpos.c (scm_primitive_exit): new procedure, terminates the
5121 process without unwinding the stack.
5123 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
5125 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
5126 argument and logior its components together, so the user doesn't
5127 have to do this explicitly. Also, if regexp/basic is supplied, then
5128 turn off REG_EXTENDED.
5129 (scm_init_regex_posix): New regexp/basic symbol.
5130 (REG_BASIC): #define this if it is not already present.
5132 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5134 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
5135 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
5136 (CLEANFILES): New target, clean versiondat.h, libpath.h.
5137 (DISTCLEANFILES): New target, clean *.x.
5138 * Makefile.in: Regenerated.
5140 Tue Jun 24 00:29:07 1997 Jim Blandy <jimb@floss.red-bean.com>
5142 * script.c (scm_compile_shell_switches): Add 1997 to copyright
5143 years in usage message.
5145 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
5146 * Makefile.in: Regenerated.
5148 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
5149 flag; I don't think we support it.
5150 (scm_make_regexp): Make sure the user doesn't pass the
5153 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
5155 (scm_init_regex_posix): Define constants for the REG_mumble flags;
5156 name them according to the SCSH convention: regexp/mumble.
5158 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
5160 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
5162 * Makefile.am (libpath.h): Include the values of all the standard
5163 Makefile directory variables. Print a message, but don't print
5165 (versiondat.h): Print a message, but don't print all the commands.
5166 * load.c: #include "alist.h".
5167 (init_build_info): New function.
5168 (scm_init_load): Call it.
5169 * Makefile.in: Regenerated.
5171 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
5173 * root.c: Establish a reliable catch-all handler for the new root.
5174 After all the Scheme handler function might signal an error too,
5175 and we don't want to lose that.
5176 (cwdr_inner_body): Renamed from cwdr_body.
5177 (cwdr_outer_body): New function, to establish the user's handler,
5178 and pass control to cwdr_inner_body.
5179 (cwdr): Establish the reliable catch-all handler here, and pass
5180 control to cwdr_outer_body.
5181 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
5182 the user's handler through to cwdr_outer_body.
5183 * throw.c (scm_handle_by_message): Move guts into....
5184 (handler_message): New static function.
5185 (scm_handle_by_message_noexit): New function.
5186 * throw.h (scm_handle_by_message_noexit): New prototype.
5188 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
5189 across this. Only works on GCC. Otherwise, we hope for the best.
5190 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
5191 the feeling that real thread systems will not need this...
5193 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
5195 Try to detect when people are using one version of libguile and a
5196 different version of ice-9. People have been skewing things and
5197 sending in bug reports.
5198 * Makefile.am (versiondat.h): New file to generate.
5199 * version.c: #include "versiondat.h", to get version info.
5200 (scm_libguile_config_stamp): New function.
5201 * script.c: #include "version.h".
5202 (scm_compile_switches): Call scm_version to get version number.
5203 * scmconfig.h.in, Makefile.in: Regenerated.
5204 * Makefile.in: Regenerated.
5206 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
5207 primitive definitions under their Scheme names.
5209 * Makefile.am (libguile_la_LDFLAGS): Update library version to
5210 1:2. Helps avoid confusion between installed and uninstalled libs.
5212 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
5215 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
5216 backslash from definition; this should be used like: GDB_INTERFACE;
5218 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5220 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
5221 new port unbuffered until its stream has been set.
5223 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
5225 * ports.h: new prototype.
5226 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
5228 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
5230 Make things compile neatly under Sun's C compiler.
5231 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
5232 * extchrs.c (xmbtowc): Make the second arg a normal char, not
5233 unsigned, because that's what the ANSI function takes.
5234 * extchrs.h (xmbtowc): Corresponding change to prototype.
5235 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
5237 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
5238 argument plain char *.
5239 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
5241 * tag.c (scm_tag): Remove unreachable statement.
5242 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
5243 top of the word, it should be unsigned.
5245 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
5246 is defined, to avoid warnings; it's only used in the
5247 conflict-checking code. Which might go away anyway.
5248 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
5249 conditionals; put the label definition in an #if too, to stifle
5252 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
5253 ChangeLog-threads in the distribution.
5254 * Makefile.in: Regenerated.
5256 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5258 * guile-snarf.in: Changed regexp to support CPPs that insert
5259 whitespace between lexical tokens (which munges the `%%%' snarf
5262 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5264 * load.c (scm_init_load_path): Append $(datadir)/guile to
5265 %load-path, so modules do not have to be installed in Guile's
5266 current version directory.
5268 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
5270 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
5271 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
5272 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
5273 call the sysdep functions with deferred ints.
5274 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
5275 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
5276 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
5279 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
5282 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
5284 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
5286 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
5288 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
5291 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
5293 * eval.c (scm_lookupcar1): New procedure to cope with a race
5294 condition during lookup (when using threads).
5295 (scm_lookupcar): Implement in terms of scm_lookupcar1.
5296 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
5299 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
5301 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
5302 supplied. (Change from Tim Pierce.)
5304 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
5306 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
5307 23:47:01 1997" changelog: Slots are now initialized with `#f' by
5308 default and not `()'. `#f' is the canonical non-value in Scheme,
5311 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5313 * struct.c (struct_printer): New variable that holds a handle on
5314 the Scheme variable *struct-printer*. This variable can be set by
5315 Scheme code to override the printing of structures.
5316 (scm_print_struct): If struct_printer is set, call it. If it is
5317 not set, or returns #f, print the structure in the old fashion.
5318 Include "eval.h" for scm_apply.
5320 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
5322 * struct.c (scm_struct_ref, scm_struct_set_x): Use
5323 scm_struct_i_n_words to get the number of fields, not
5324 -scm_struct_n_extra_words.
5326 On the route to fancier struct printing:
5327 * struct.c (scm_print_struct): New function to print a structure.
5328 Include "genio.h" to support it. This function doesn't do
5329 anything interesting right now, but I think it should be here
5331 * struct.h: Include "print.h" and add prototype for
5333 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
5334 print structures ourself.
5336 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5338 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
5339 before applying the handler in case it doesn't return.
5341 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
5343 * scmsigs.h, async.h: updated.
5345 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
5348 * posix.c (scm_uname): interpret only negative values as an error.
5349 Solaris normally returns a positive value.
5351 * script.c (scm_compile_shell_switches): if we are not going into
5352 an interactive repl, set scm_mask_ints to zero so that asyncs can
5355 * simpos.c (scm_system): don't ignore/unignore signals around
5358 * posix.c (scm_open_pipe): don't ignore/unignore signals around
5361 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
5362 done in boot-9.scm instead.
5364 * scmsigs.c, async.c: Major rewriting of signal handling code.
5365 (scm_sigaction): new procedure.
5366 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
5368 (scm_raise): return unspecified, throw error on failure.
5370 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5372 * regex-posix.c (scm_init_regex_posix): Register the "regex"
5373 feature, to help boot-9.scm decide whether to import the regex
5376 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5378 * eval.c: Include scmconfig.h at the beginning of the file so that
5379 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
5382 * regex-posix.c: #include "_scm.h" before conditionally #including
5383 <regex.h>; the former defines HAVE_REGCOMP.
5385 * regex-posix.c: #include <regex.h> conditionally, so the file is
5386 CPP'able (for dependency scanning) even on systems that don't have
5389 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5391 Add new R4RS-compliant syntax for keywords.
5392 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5393 regardless of the setting of the `keywords' read option.
5394 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5395 can be re-read no matter what the setting of the `keywords' read
5398 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5400 Add support for POSIX regular expressions.
5402 * regex-posix.c, regex-posix.h: New files. (Some code
5403 is taken liberally from rx/rgx.c in the old Guile dist.)
5405 * init.c: Include regex-posix.h.
5406 (scm_boot_guile_1): Call scm_init_regex_posix.
5408 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5409 Add regex-posix.[ch] sources.
5410 * Makefile.in: Regenerated.
5412 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5413 to do this automatically? It didn't for me, bleh.)
5415 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5417 * fports.c (print_pipe_port): New function.
5418 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5419 latter doesn't even take the right arguments.
5421 * Makefile.am: Increment shared lib revision number. I think
5422 sometimes the uninstalled Guile finds the installed shared lib;
5423 Gord says doing this might help. As things turned out, I can't
5424 say whether it does.
5425 * Makefile.in: Regenerated.
5427 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5428 passing it as the closure argument to scm_boot_guile. (Bill
5431 * ports.c (print_void_port, putc_void_port, puts_void_port,
5432 write_void_port, flush_void_port, getc_void_port, close_void_port,
5433 noop0): Use ANSI prototypes instead of K&R declarations, so the
5434 initialization of void_port_ptob gets aggressively type-checked.
5435 Fix arguments of print_void_port and write_void_port. (Bill

5472 here; apparently it's not quite right to have const in a prototype
5473 and then use a K&R declaration. I wonder if stuff like this will
5474 go away if we compile with -Wrequire-prototypes, or whatever that
5475 is... (Bernard URBAN)
5477 * scmhob.h: New text from Bernard URBAN.
5479 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5481 * script.c: Don't #define const on hpux. Configure takes care of
5482 this. (Thanks to Larry Schwimmer.)
5484 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5485 decide whether to #include <unistd.h>, instead of listing a bunch
5486 of systems. Don't #include stdio twice. Removed dyked-out
5487 definition of scm_find_impl_file.
5489 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5491 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5492 library version info to 1:0.
5493 * Makefile.in: Regenerated.
5495 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,
5496 gdb_interface.h, gdbint.c, gdbint.h, gh_data.c, gh_init.c,
5497 gh_io.c, gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c,
5498 init.c, net_db.c, options.c, options.h, ports.c, print.c, read.c,
5499 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5500 throw.c: Update copyright years; these files have been worked on
5501 significantly in 1997, but only had copyright years for 1996.
5502 Also, change name of copyright holder on some from Mikael
5503 Djurfeldt to Free Software Foundation; he has signed papers
5504 assigning the changes to the FSF.
5506 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5507 reason not to give the user the option.
5509 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5510 Return #f on end-of-file when scanning table (i.e. when called
5511 with no arguments). Try to catch errors, when we can.
5512 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5514 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5515 external declarations. These are useful.
5517 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5519 * posix.c: don't include <sys/select.h> or define macros for
5520 select, since they were not used in this file.
5522 * filesys.c (scm_select): make the fifth parameter microseconds,
5523 not milliseconds. let the fourth parameter be either a real value
5524 or an integer or #f. The first, second and third arguments can
5525 now be vectors: the type of the corresponding return set will be
5527 (set_element, get_element): new static procedures.
5529 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5531 * strports.c (scm_eval_string): New function.

5536 * net_db.c (h_errno): Add extern decl for this.
5538 * fports.c (local_pclose): New function.
5539 (scm_pipob): Use it in the initializer here.
5542 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5543 Use a meaningful error message when signalling an error. For
5544 this, scm_gethost must check h_errno rather than errno.
5546 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5548 * Makefile.in: Regenerated, using automake-1.1p.
5550 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5552 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5553 not SCM_UNSPECIFIED.
5555 * script.c (scm_compile_shell_switches): don't append (quit) if
5557 (scm_shell): call scm_exit_status and exit on the result of the
5560 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5562 Ensure that shared substrings are handled properly when passed to
5563 a system call or other foreign function. Many thanks to Tim
5565 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5566 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5567 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5568 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
5569 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
5570 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5571 (scm_display_error_message): use RO macros when strings may be RO.
5572 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5573 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5574 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
5575 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
5576 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
5577 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
5578 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
5579 scm_strftime), vports.c (scm_make_soft_port): use
5580 SCM_COERCE_SUBSTR to make sure shared substrings are

5585 * error.c (scm_error): Add newline to error message.
5587 * init.c (scm_init_standard_ports): Doc fix.
5589 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5591 * dynl-shl.c: Completely replaced with new code from Bernard
5594 * script.c (scm_ice_9_already_loaded): New variable.
5595 (scm_compile_shell_switches): Use it.
5597 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5599 * filesys.c (scm_input_waiting_p): add missing third argument to
5602 * stime.c (scm_localtime): copy the result of localtime before
5603 calling gmtime in case they share a buffer.
5604 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5607 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5609 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5611 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5613 * Makefile.am (check-local): New target, which causes 'make check'
5614 to run gh_test_c and gh_test_repl, with some trivial input.
5615 * Makefile.in: Rgnrtd.
5617 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5619 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5622 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5624 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5625 sure how this was supposed to work.
5626 (scm_async_click): don't send SCM_TICK_SIGNAL.
5627 (scm_init_async): don't initialize %tick-thunk.
5629 * the following change doesn't affect the Scheme interface:
5630 gc-thunk is called at the end of garbage collection. however it's
5631 no longer implemented by pretending it's a signal.
5633 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5634 system async corresponding to scm_gc_thunk.
5635 * async.h: declare scm_gc_async.
5636 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5637 gc-thunk directly, instead of going through a signal handler.
5638 (scm_gc_async): new variable, points to the GC system-async.
5639 (scm_init_async): save the GC async as scm_gc_async instead
5640 of using system_signal_asyncs.
5641 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5643 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
5645 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
5646 Don't screw up if we're interrupted.
5647 * Makefile.in: Regeneradet.
5649 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5651 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5653 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5654 we're not using AM_INIT_GUILE_MODULE any more.
5655 * Makefile.in: Reneregated.
5657 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5659 Functions for finding variable bindings, grace à Tim Pierce.
5660 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5661 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5663 Get 'make dist' to work again.
5664 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5665 * Makefile.in: Regenerated, like a surry without a fringe on top.
5667 Changes for reduced Guile distribution: one configure script,
5669 * configure.in, configure: Removed.
5670 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5671 real configure script lives.
5672 * Makefile.in, scmconfig.h.in: Regenerated.
5674 * init.c: #include "script.h", to get prototype for script.c's
5677 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5679 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5680 scm_must_malloc, not raw malloc.
5682 * script.c (scm_compile_shell_switches): Dyke out debugging output
5685 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5687 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5689 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5690 system has them. Hope this is safe. Previously
5691 sys/timeb.h was included if HAVE_FTIME was defined or if
5692 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5693 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5695 * ioext.c (scm_setfileno): add missing third argument to
5696 scm_misc_error call.
5698 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5700 * eq.c (scm_equal_p): Correctly compare strings of different
5701 varieties. (Thanks to Tim Pierce.)
5703 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5705 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5706 #! block comment must occur on a line all by itself.
5708 Move most of the guts of shell command processing into libguile,
5709 so guile.c can be very small (and eventuallly auto-generated. (I
5710 mean, generated mechanically, not self-generated. Hmm.))
5711 * guile.c, script.c, script.h: New source files.
5712 * init.c (scm_boot_guile_1): Call scm_init_script.
5713 * libguile.h: #include "script.h".
5714 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5715 targets, for new executable.
5716 (libguile_la_SOURCES): Mention script.c.
5717 (modinclude_HEADERS): Add script.h.
5718 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5719 not dynamic linking is enabled. This is because we're generating
5720 executables now. Move CY_AC_WITH_THREADS call after those, so the
5721 values of cy_cv_threads_libs captures the libs chosen above.
5722 * Makefile.in, configure, aclocal.m4: Regenerated.
5724 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5725 We don't maintain this interface any more, and it just confuses
5728 * alloca.c: #include <scmconfig.h>, not <config.h>.
5729 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5730 it'll get included in disties.
5732 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5734 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5735 be distributed, because they confuse people.
5736 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5738 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5740 * configure.in: check for presence of gethostent (not present on
5741 OpenBSD by default).
5742 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5743 * configure, scmconfig.h.in: Regenerated.
5745 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5747 * backtrace.c (scm_backtrace): Split message string across
5748 newlines properly. GCC is more tolerant of this than other
5751 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5753 Merge threads directory into libguile.
5754 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5755 threads.h: New source files.
5756 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
5757 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5759 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5760 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5761 coop-threads.c.cygnus, coop-threads.h.cygnus.
5762 * configure.in: If we're using threads, include threads.o in
5764 * _scm.h, libguile.h: threads.h lives in this directory now.
5765 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5766 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5767 currently used, but brought along for information's sake.
5768 * ChangeLog-threads: log from old 'threads' directory.
5769 * Makefile.in, configure: Rebuilt.
5771 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5773 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5776 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5778 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5780 Merge GH interface library into libguile.
5781 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5782 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5783 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5784 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5786 (EXTRA_libguile_la_SOURCES): ... here.
5787 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5788 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5789 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5790 New variables, describing how to build the gh test programs.
5791 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5792 build the test programs, and we probably should have been linking
5793 libguile.la against them all along, to support AIX shared libs.
5794 Add cflags for threads to CFLAGS; add libs for threads to new
5795 variable THREAD_LIBS, used in Makefile.am.
5796 * ChangeLog-gh: log from old `gh' subdirectory.
5797 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5799 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5801 * acconfig.h: Undo change of Apr 9; including the definition of
5802 PACKAGE in the guile headers conflicts with applications' own
5804 * scmconfig.h.in: Regenerated.
5806 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

5813 when PROC is receiving no arguments.
5815 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5817 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5818 have S_IFSOCK. This is the case under Ultrix.
5820 * posix.c (scm_status_exit_val, scm_status_exit_val,
5821 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5822 Ultrix versions of WIFSTOPPED, etc., which assume that their
5823 arguments are lvalues (hmm).
5825 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5827 * eval.c: Doc fixes.
5829 * throw.c: Doc fixes; rearranged.
5831 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

5835 * acconfig.h: Added entry for PACKAGE.
5836 * scmconfig.h.in: Regenerated.

5839 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5840 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5842 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5844 * Makefile.in: Rebuild.
5846 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5848 * stime.c (scm_mktime): take an optional zone argument.
5849 (scm_localtime): check putenv return value.
5850 (scm_strftime, scm_strptime): moved from posix.c. move #include
5852 stime.h, posix.h: update prototypes.
5853 (bdtime2c, setzone, restorezone): new static procedures.
5854 (scm_mktime, scm_strftime): use them.
5855 (scm_strftime): don't call mktime before strftime. Use
5856 filltime for return value.
5857 (filltime): convert NULL zname to #f.
5858 (scm_strptime): return a count of characters consumed, not
5859 the remaining string.
5861 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5863 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

5870 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5872 * stime.c (scm_init_stime): don't define ticks/sec.
5873 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5874 return value problem and is still portable.)
5876 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5878 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5879 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5880 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5881 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5882 cpp_err_symbols.c): Corresponding changes.
5883 * Makefile.in: Regenerated.
5885 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>

5890 * putenv.c: new file, from sh-utils 1.12.
5892 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5893 since allocation isn't for Scheme objects.
5894 (scm_putenv): copy strings before placing in the environment.
5896 * stime.c (scm_current_time): throw an error if time returns -1,
5897 instead of returning #f.
5898 (scm_get_internal_real_time, scm_get_internal_real_time): use
5899 scm_long2num for return value instead of SCM_MAKINUM.
5901 * stime.h: prototypes updated.
5903 * stime.c (scm_time_in_msec): apparently unused, deleted.
5905 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5907 * configure.in: check for gettimeofday.
5909 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5910 which may be more usefully portable than a gettimeofday interface.
5912 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5914 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5916 * Makefile.in: Regenerated.
5918 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5920 * stime.c (filltime): recovered static procedure.
5921 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5924 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5925 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5927 * posix.c (scm_mknod): split the mode argument into type and perms
5928 arguments, like the extra fields returned by stat.
5930 * fports.c (scm_pipob): set the close, free and print procedures.
5931 (scm_close_pipe): new procedure.
5933 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5934 define them in boot-9.scm
5936 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5938 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5939 wan't defined. Don't include fd.h.
5941 * Previously fd.h was regenerated whenever configure was run,
5942 forcing a couple of files to be recompiled.
5944 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5945 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5946 Check for _fileno as well as _file.
5948 * ioext.c: don't fd.h.
5949 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5952 * Change the stratigy for getting information about errno
5953 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5954 generating lists of symbols during the build process, which will
5955 not always work, include comprehensive lists in the distribution.
5956 To help keep the lists up to date, the "check_signals" and
5957 "check_errnos" make targets can be used.
5959 * configure.in: don't check for a command to extract errno codes.
5960 * Makefile.am: update file lists, remove errnos.list and errnos.c
5961 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5962 check_errnos targets.
5963 (CLEANFILES): remove errnos.c and errnos.list, add
5964 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5965 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5966 * errnos.default: deleted.
5967 * cpp_signal.c: new file.
5968 * cpp_errno.c: renamed from errnos_get.c.
5969 * cpp_err_symbols, cpp_sig_symbols: new files.
5970 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5971 * error.c (scm_init_error): #include cpp_err_symbols instead of
5973 * posix.c (scm_init_posix): don't intern signal symbols. #include
5976 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5978 * strop.c (scm_i_index): allow the lower bound to be equal to the
5979 length of the string, so a null string doesn't always give an error.
5981 * posix.h: new prototypes.
5982 * posix.c (scm_status_exit_val, scm_status_term_sig,
5983 scm_status_stop_sig): new functions, as in scsh. They break down
5984 process status values as returned by waitpid.
5986 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5988 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5989 configure doesn't know about it.
5991 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5993 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5995 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5996 which defines C variables with global linkage.
5998 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6000 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
6003 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
6005 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
6006 has time to check why this doesn't work well with continuations.
6008 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
6010 * Fix shell syntax error; some shells won't tolerate
6011 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
6013 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
6015 * posix.c (scm_uname): throw an error if uname fails instead
6018 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
6020 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
6023 * async.c (scm_ints_disabled): definition moved from error.c.
6025 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6027 * acconfig.h: Removed PACKAGE.
6029 * scmconfig.h.in: Regenerated.
6031 * snarf.h: g++ says it's non-portable not to specify the first
6032 argument in a varargs declaration. I introduced the first
6033 argument by using preprocessor conditionals.
6035 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
6037 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
6038 (scm_freopen): use RO string macros for filename and modes.
6039 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
6041 * posix.c (scm_getgrgid): simplify conversion of name to C string.
6042 (scm_mknod): use RO string macros for path.
6044 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
6045 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
6047 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
6048 use SCM_ROSTRINGP and SCM_ROCHARS.
6050 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6052 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
6055 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
6056 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
6057 support for byte vectors.
6059 * print.c (scm_iprin1): Limit number of vector elements printed
6060 according to pstate->length.
6062 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6064 * backtrace.c (scm_display_error_message): don't segv if message
6067 * error.h: prototype for scm_error_scm.
6069 * error.c (scm_error_scm): new procedure, reimplements scm-error
6070 in C and uses scm_error.
6072 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6074 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
6075 pointer to the Scheme variable read-hash-procedures and intern it
6076 in scm_init_read. Modify scm_read_hash_extend and
6077 scm_get_hash_procedure to use the pointer.
6079 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6081 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
6082 (SCM_KEYWORD_STYLE): defined.
6084 * read.c (scm_read_opts): add a keywords option. This isn't a
6085 boolean option, in case someone wants to add support for DSSSL
6087 Setup scm_keyword_prefix symbol.
6088 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
6090 I've left keyword support disabled by default, since it doesn't
6091 seem to break the module system and it gives R4RS standard behaviour.
6092 It can be reactivated with (read-set! keywords 'prefix).
6094 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6096 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
6097 before constructing arbiter.
6099 * eval.c (scm_m_define): Bugfix: Check that the object is a
6100 closure before setting the procedure property!
6102 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
6104 * ports.c: Removed `ungetc-char-ready?'.
6106 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
6108 * read.c (scm_init_read): intitialise scm_read_hash_procedures
6109 (idea from Mikael: make it a pair so scm_permanent object only
6111 (scm_read_hash_extend): don't call scm_permanent_object.
6112 (ideas from Mikael): if chr is already in the list, replace its
6113 procedure instead of appending it again. If proc is #f, remove
6115 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
6117 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
6119 * gdbint.c (gdb_read): update scm_lreadr usage.
6121 * load.h: update prototypes.
6123 * load.c (scm_primitive_load, scm_read_and_eval_x,
6124 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
6126 * read.h: add prototype for scm_read_hash_extend. Change args for
6129 * read.c (scm_read_hash_procedures): new variable.
6130 (scm_read_hash_extend): new procedure.
6131 (scm_get_hash_procedure): new procedure.
6132 (scm_lreadr): use scm_get_hash_procedure instead of an argument
6133 for extended # processing.
6134 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
6135 scm_read_token): remove case_i, sharp arguments. Change callers.
6137 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
6139 * read.h (SCM_N_READ_OPTIONS): increase to 3.
6140 (SCM_CASE_INSENSITIVE_P): define.
6142 * read.c: add case-insensitive option to scm_read_opts.
6143 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
6144 to determine whether to convert symbol case.
6145 (default_case_i): definition removed.
6146 * read.c (scm_read_token): if case_i, downcase ic before doing
6149 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6151 * configure.in: Added configuration option `guile-debug'.
6152 Configure with --enable-guile-debug if you want a bunch of extra
6153 functions used for debugging when developing Guile.
6155 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
6157 * procs.c (make-cclo): New undocumented debugging procedure: Make
6158 compiled closure with internal procedure PROC and length LENGTH.
6159 Only compiled if GUILE_DEBUG is defined.
6161 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
6163 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
6165 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
6167 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
6168 with 3 or more args internally to the evaluator.
6170 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6172 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
6173 with 3 or more args internally to the evaluator. This is mainly
6174 because we don't want to pass entry and exit points of the
6175 debug support twice, but it also seems to increase the speed of
6176 the evaluator for such calls (e. g. (+ 1 2 3)).
6178 * backtrace.c (scm_display_application): New procedure:
6179 display-application; Set fancy printing parameters individually
6180 for different types of display (backtrace, error, application).
6181 (These should of course be customizable!)
6183 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
6184 clear the CHECK-flags.
6186 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6188 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
6190 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6192 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
6193 from pairs with a GLOC in the car.
6195 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
6196 otherwise `symbol-hash' will behave badly.
6197 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
6198 we get segmentation fault!
6200 * symbols.c: Added #include "weaks.h". New functions:
6201 `builtin-bindings' and `builtin-weak-bindings'. (These will be
6202 moved to an extraneous library when we split libguile.)
6204 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6206 * filesys.c (scm_stat): stat now takes fport arguments too as
6207 documented in the manual.
6209 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6211 * debug.c (scm_single_step): Bugfix: Call continuation with
6212 scm_call_continuation instead of throwing to it.
6214 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
6216 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
6217 argument wasn't declared to be optional.
6219 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6221 * stime.c (scm_init_stime): Add feature "current-time".
6223 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6225 * throw.h: prototype for scm_exit_status.
6226 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
6227 args to derive an exit status. Allows (quit) to work from a
6229 (scm_exit_status): new function.
6232 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6234 * eval.c (scm_deval): Removed some old code.
6235 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
6237 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
6240 * symbols.c (msymbolize): Bugfix: Must initialize property list to
6243 * procs.c: Introduce the existent C function scm_thunk_p at the
6244 Scheme level as well.
6246 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6248 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
6249 used from C to easily lookup the value of a symbol in the current
6252 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6254 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
6255 scm_init_unif in this file. This will also fix a previous problem
6258 * configure.in: Added AM_MAINTAINER_MODE
6260 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6262 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
6265 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6267 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
6268 source files that are not always included in libguile but should
6269 have their dependencies calculated by automake. This variable is
6270 recognized by automake, no further magic is needed.
6271 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
6272 to deal exclusively with *.lo files, as it seems. The *.o files
6273 are built automatically when the corresponding *.lo file gets
6276 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
6278 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
6281 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
6283 * unif.c (scm_array_set_x): minor change to argument error checking.
6285 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
6287 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
6288 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
6289 They should only be included in the library at configure.in's
6291 (libguile_la_LDADD): Include the appropriate .lo files here.
6292 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
6293 so we know when to build them (and their .lo bretheren).
6294 * configure.in (LIBLOBJS): New substituted variable. We let
6295 configure decide which .o files to include in LIBOBJS, and then
6296 put the corresponding list of .lo files in LIBLOBJS. The latter
6297 is what we pass to libtool.
6298 * Makefile.in, configure: regenerated.
6300 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
6302 * symbols.c (scm_sysintern0): New function. Contains the core of
6303 old scm_sysintern but doesn't take a second value argument.
6304 (scm_sysintern): Now uses scm_sysintern0.
6305 (scm_sysintern_no_module_lookup): Renamed to
6306 scm_sysintern0_no_module_lookup and doesn't take a second value
6307 argument any longer.
6309 * symbols.h (scm_sysintern0: Added declaration.
6311 * options.c (scm_init_opts): Use scm_sysintern0 instead of
6312 scm_sysintern when interning option keys. Otherwise we risk
6313 destroying the values of already interned variables.
6315 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
6316 scheme-level boolean (use SCM_NFALSEP).
6318 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
6320 (scm_backtrace): New function. (C version of old function from
6321 boot-9.scm) Motivation: Make it possible to display backtraces
6322 without depending on boot-9.scm. (I'm uncertain if this
6323 motivation is good enough...)
6325 * root.h (scm_root_state): Add member the_last_stack_var.
6326 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
6328 * root.c (mark_root): Mark scm_the_last_stack_var.
6330 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
6333 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
6335 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
6336 1. mark_lazy_catch didn't mark the smob.
6337 2. Both functions above have standard variants:
6338 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
6339 free_lazy_catch --> scm_free0.
6341 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
6343 * throw.c (scm_internal_lazy_catch): New function.
6344 (scm_lazy_catch): Rewritten to use it.
6345 (scm_ithrow): Handle the new lazy catch representation.
6346 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
6347 that doesn't have a jmpbuf is a lazy catch clause.
6348 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
6349 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
6350 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
6352 (scm_init_throw): Register the new lazy-catch smob type.
6353 * throw.h (scm_internal_lazy_catch): decl for new function.
6355 * throw.c (scm_internal_catch): Doc fixes.
6357 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
6358 configure.in. Including this might cause problems if applications
6359 that link against libguile include their own copies of alloca, but
6360 if they're using autoconf, they should be adding libguile to LIBS
6361 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
6362 the copy in libguile, and things will be okay. (I think.)
6364 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6366 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
6368 strop.h: move prototypes too.
6370 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6372 * posix.c (scm_init_posix): don't intern EINTR since it's now done
6375 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
6376 etc. I deleted them from filesys.c long ago, but didn't
6377 notice they were here too (although ineffective since
6378 sys/stat.h wasn't included).
6380 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
6382 * eval.c: Don't define alloca in GCC case. gcc will automatically
6383 use __builtin_alloca if appropriate.
6385 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6387 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6388 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6389 that values of automatic variables are preserved. See comments
6390 for safe_setjmp for details.
6392 Change from Thomas Morgan:
6393 * variable.c: Include eq.h.
6394 (var_equal): New function.
6395 (variable_smob): Use var_equal as the discriminator for variables.
6397 * throw.c (s_throw): Remove extraneous declaration.
6399 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6400 * eval.c: Add necessary CPP cruft to support that.
6401 * configure, Makefile.in, scmconfig.h.in: regenerated.
6403 Change from Thomas Morgan:
6404 * procprop.c (scm_procedure_properties): Convert the Scheme
6405 boolean returned by scm_procedure_p into a C boolean before using
6406 it as a condition for SCM_ASSERT.
6407 (scm_procedure_property): Likewise.
6409 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6410 indications of Unixness.
6413 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6415 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6417 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6419 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6420 "unknown # object" error messages.
6422 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6423 (scm_i_index) and declare it static. Add a 'direction' argument
6424 to indicate what way the search should go.
6425 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6427 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6428 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6430 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6432 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6434 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6435 to avoid clash with various scsh forks.
6437 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6439 The following two changes (ramap.c, throw.c) are motivated by the
6440 apparent unportability of forward declarations of static arrays of
6441 the form `static foo bar[];'.
6443 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6444 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6446 * throw.c (scm_throw): Moved above scm_ithrow.
6448 * options.h: Removed the extern declarations of scm_yes_sym and
6449 scm_no_sym since these are static.
6451 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6453 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6455 * Makefile.am: remove AWK=@AWK@.
6456 Add a rule for generating errnos.list.
6457 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6459 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6460 don't extract errnos, just set a variable (avoids the
6461 need to recompile error.c just because configure is run.)
6463 * unif.h: update prototypes.
6464 * unif.c (scm_uniform_array_read,write): change the offset and
6465 length arguments to start and end, for consistency.
6467 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6469 * ioext.h: update prototypes.
6470 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6471 scm_read_line_x, it's a more general procedure using an
6472 interface from scsh. read-line and read-line! are now defined
6474 Note that the new read-line trims the terminator
6475 by default, previously it was appended to the returned string. An
6476 optional argument specifies how to process the terminator (scsh
6477 compatible). For the old behaviour: (read-line port 'concat).
6478 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6479 returns a pair, but is converted to multiple values if the scsh
6482 socket.h: update prototypes.
6483 * socket.c (scm_recvfrom): for consistency with other procedures,
6484 take start and end as separate optional arguments.
6485 (scm_recv, scm_recvfrom): don't allow the second argument
6486 to be a size, only a buffer. Change the scheme names to
6487 recv! and recvfrom!. Don't return the buffer.
6489 * ioext.h, posix.h: move prototypes too.
6490 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6491 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6492 "read.h" and "unif.h".
6493 * ioext.c: include "chars.h"
6495 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6497 * dynl.c: The dynamic linking and module registration functions
6498 are now defined even when dynamic linking is not available for the
6499 host system. Some of their functionality can be done without
6500 dynamic linking; when it's really needed, they throw errors.
6502 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6504 * configure.in: Only define DYNAMIC_LINKING when one of the system
6505 dependent functions is detected.
6506 * dynl.c (scm_dynamic_func): New function to get the address of a
6507 function in a dynamic object.
6508 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6509 produced by scm_dynamic_func as the thing to call.
6511 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6513 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6514 (scm_register_module_xxx, scm_registered_modules,
6515 scm_clear_registered_modules): New functions.
6517 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6519 * symbols.c (scm_sysintern): Renamed to
6520 scm_sysintern_no_module_lookup.
6521 (scm_sysintern): New function to take the place of the old
6522 scm_sysintern. It uses the current toplevel lookup closure to give
6523 the symbol its value. This is a temporary hack to put packages
6524 like gtcltk into their own module.
6525 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6526 us whether `scm_top_level_lookup_closure_var' has been initialized
6528 * eval.c (scm_init_eval): Set it.
6530 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6532 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6533 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6535 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6537 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6538 scm_sys_dup): deleted: FD capability will be added to other
6540 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6541 scm_fd_free, fd_smob, scm_intern_fd.
6542 (scm_open): renamed from scm_sys_open. Return a port instead of
6543 an FD object. Make the mode argument optional.
6544 (scm_sys_create): deleted, it's just a special case of open.
6545 (scm_init_filesys): move interning of constants O_CREAT etc.,
6546 here (were previously using SCM_CONST_LONG macro).
6547 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6549 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6550 include "fports.h" and <stdio.h>
6551 (scm_stat, scm_select): don't support FD objects.
6553 * error.h: adjust scm_syserror_msg prototype.
6554 * error.c (scm_syserror_msg): take an extra argument for errno.
6555 Using the global value didn't always work, since it could be
6556 reset by procedure calls in the message or args arguments.
6558 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6559 I don't understand why the check was there (and what about the
6562 * strop.c (scm_string_copy): allow shared substrings to be copied.
6564 * unif.h: corresponding change to prototypes.
6565 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6566 recognize two new optional arguments: offset and length. Allow
6567 the port argument to be an integer (file descriptor, for scsh).
6568 Include <unistd.h> for "read" prototype.
6570 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6572 * socket.c: don't include filesys.h.
6574 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6576 * Makefile.am: add AWK=@AWK@ (?)
6578 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6580 Add a rule to generate errnos.c from errnos.
6581 * error.c (scm_init_error): include errnos.c.
6582 * errnos_cnvt.awk: new file, converts the list of errno codes to
6584 * errnos_get.c: new file.
6585 * errnos.default: new file, contains errnos to try if they can't
6586 be extracted from errno.h.
6587 * configure.in: if using GCC, try and extract errno codes from
6591 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6593 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6594 * Makefile.am: Made libguile into a libtool library.
6595 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6596 Set libtool_libs to indicate that libguile is a libtool library.
6597 See guile/ChangeLog for details.
6598 * .cvsignore: ignore "*.lo", the libtool library objects.
6600 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6602 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6603 use htons in getservbyport argument.
6605 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6607 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6608 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6611 * objprop.c (scm_object_property): No need to take the CDR of the
6612 value returned by scm_object_properties, since Aug 20 change.
6614 * configure.in: When checking for struct linger, #include
6615 <sys/types.h> as well as <sys/socket.h>. I've never known
6616 <sys/types.h> to cause any portability problems, and Solaris's
6617 <sys/socket.h> needs it.
6618 * configure: Rebuilt.
6620 I think the Sun compiler has chosen a perverse way to interpret
6621 ANSI declarations combined with K&R definitions. We'll
6622 appease it a little bit. But when it invades France, we fight.
6623 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6624 * print.h (scm_iprlist): Here too.
6625 * numbers.c (scm_divbigdig): Change definition to match
6626 declaration in numbers.h.
6627 * unif.c (scm_makflo): Change definition to match declaration in
6630 * init.c (scm_boot_guile): Don't return the value of
6631 scm_boot_guile_1. This function doesn't return a value;
6632 scm_boot_guile_1 doesn't return a value (or return at all).
6634 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6637 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6638 compile. I have a feeling this function is a bad idea anyway ---
6639 one should always test for features, not systems.
6641 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6642 semicolons. Only pure luck kept this from being noticed earlier.
6644 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6646 * socket.c (scm_recvfrom): Added missing semicolon.
6648 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6650 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6651 the buffer and start and end positions for scsh networking
6654 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6656 * configure.in: Revert previous change to this file; the problem
6657 is due to transient automake weirdness.
6658 * configure: Rebuilt.
6660 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6661 PLUGIN/guile.libs. configure generates the latter from the former.
6662 * Makefile.in: Rebuilt.
6664 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6665 need this if we install scripts, like guile-snarf.
6666 * configure: Rebuilt.
6668 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6670 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6672 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6674 * socket.c (scm_addr_vector): fix faulty scm_listify.
6676 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6678 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6679 style block comment is no longer considered an error.
6681 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6683 * PLUGIN/guile.libs.in: New file.
6684 * PLUGIN/guile.libs: Removed from repository.
6685 * configure.in: Create PLUGIN/guile.libs from
6686 PLUGIN/guile.libs.in. This is for including additonal libraries
6687 needed for dynamic linking.
6688 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6689 instead of PLUGIN/guile.libs.
6691 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6693 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6695 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6696 occurrences of the given element from the list, not just the
6697 first. This is how the Emacs Lisp functions behave, how the
6698 analogous Common Lisp functions behave, and (I believe) how the
6699 older Maclisp functions worked. I realize that this change may
6700 break code, but it seemed better to break it before the Guile
6703 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6704 Their prototypes were already present in gc.h, but they weren't
6706 (scm_init_storage): Initialize scm_protects.
6707 * root.c (scm_protects): New element of scm_sys_protects.
6709 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6711 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6713 * libguile.h: Added #include "libguile/net_db.h".
6715 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6716 30 change. That file is only meant for communication between the
6717 configuration process and load.c. If code linked against libguile
6718 wants to get at the paths mentioned in libpath.h, it can call
6719 functions declared in load.h.
6721 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6723 * libguile.h: Removed #include "libguile/fdsocket.h"
6725 * net_db.c: Added #include <sys/socket.h>.
6727 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6729 * filesys.c (scm_input_waiting_p): use select in preference to
6730 FIONREAD, since the latter doesn't detect EOF.
6731 Throw error if neither select nor FIONREAD available.
6733 * socket.c (scm_connect): take a port, not a fd object.
6734 (scm_fill_sockaddr): throw an error if fam is not recognised.
6735 (scm_bind): use scm_fill_sockaddr.
6736 (scm_listen): take a port, not a fd object.
6737 (scm_accept): take and return a port. return #f in the car if
6738 address can't be got
6739 (scm_sock_fd_to_port): new procedure.
6740 (scm_socket): use scm_sock_fd_to_port.
6741 (scm_addr_vector): throw error if unrecognised address type.
6742 take an extra argument with the calling procedure name.
6743 (scm_getsockname): take a port. return #f if address can't be got.
6744 (scm_getpeername): take a port. return #f if address can't be got.
6745 (scm_recvfrom): take a port. return #f for address component if can't
6747 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6748 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6750 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6752 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6753 use separate data pointers, to allow them to be designed
6754 independently and reused.
6755 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6756 Renamed from catch_body, catch_handler, and uncaught_throw; made
6758 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6760 (scm_catch): Use the above.
6761 (scm_throw): Don't bother printing a message for an uncaught
6762 throw; we establish a default handler in init.
6763 * throw.h (scm_internal_catch): Prototype updated.
6764 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6766 (struct scm_body_thunk_data): New structure, used as data
6767 argument to scm_body_thunk.
6768 * init.c (struct main_func_closure): New structure, packaging up
6769 the data to pass to the user's main function.
6770 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6771 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6772 scm_internal_catch to establish a catch-all handler, using
6773 scm_handle_by_message. This replaces the special-case code in
6775 (invoke_main_func): Body function for scm_internal_catch; invoke
6776 the user's main function, using the main_func_closure pointer to
6777 decide what to pass it.
6778 * root.c (struct cwdr_body_data): Remove handler_proc member.
6779 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6780 (cwdr_handler): Removed.
6782 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6784 * socket.h (SCM_P): update bind prototype.
6785 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6786 include "feature.h".
6787 (scm_socket): return a port, not a file descriptor object.
6788 include "fports.h" and <unistd.h>
6789 (scm_bind): take a port, not a file descriptor object.
6790 take an extra argument for address args.
6792 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6793 INADDR_NONE, INADDR_LOOPBACK.
6795 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6797 * init.c: include net_db.h and not fdsocket.h.
6798 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6800 * Makefile.am: corresponding changes.
6801 * socket.h: renamed from fdsocket.h, fix names.
6802 * net_db.h: renamed from socket.h, fix names.
6803 * socket.c: renamed from fdsocket.c.
6804 remove _sys from procedure names.
6805 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6806 add "socket" to features list.
6807 * net_db.c: renamed from socket.c.
6808 remove _sys from procedure names.
6809 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6810 add "net-db" to features list.
6811 include "net_db.h". don't include <sys/socket.h> or
6814 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6816 * tags.h (scm_tags): Removed comma at end of last enumerator.
6818 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6820 Don't use GCC extensions to allocate space for debugging frames.
6821 (Here he goes again! Why do we put up with this?!)
6822 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6823 an scm_debug_info structure, not an in-line array of them. Add
6824 'info' member, to say how many vect elements we've used, for eval
6826 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6827 a new variable debug_info_end to mark the end of vect, instead of
6828 the address of the 'info' pointer itself.
6829 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6830 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6831 (SCM_APPLY): Explicitly allocate space for debug.vect.
6832 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6833 * stacks.c: Adjusted for new debug frame structure.
6834 (RELOC_INFO, RELOC_FRAME): New macros.
6835 (stack_depth, read_frames): Use them, and new scm_debug_frame
6836 element 'info', instead of magically knowing that eval frames have
6837 an info pointer sitting after vect.
6838 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6840 (scm_init_stacks): Formatting tweaks.
6842 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6844 Give GCC more control flow information, so it can be sure that
6845 variables aren't used uninitialized.
6846 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6847 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6848 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6849 scm_misc_error): Tell GCC that these functions never return.
6850 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6851 out the field type, call abort if SCM_ASSERT returns, to placate
6853 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6854 scm_wta ever returns. We can't handle this case anyway, and this
6855 gives the optimizer more information.
6856 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6857 scm_wta ever returns.
6859 In some cases, the code is fine, but GCC isn't smart enough to
6860 figure that out; this usually happens when one variable is only
6861 initialized and used when a particular condition holds true, and
6862 we know that condition will never change within a given invocation
6863 of the function. In this case, we simply initialize the variables
6864 to placate the compiler, hopefully to a value which will cause a
6865 crash if it is ever actually used.
6866 * print.c (scm_iprin1): Initialize mw_pos.
6867 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6868 * throw.c (scm_ithrow): Initialize dynpair.
6869 * unif.c (scm_uniform_vector_ref): Initialize cra.
6870 * struct.c (init_struct): Initialize prot.
6871 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6873 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6874 if EXPR contains no expressions.
6876 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6878 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6879 cause an infinite loop (???). So much for the algebraic
6880 equivalency of variable-sized arrays and alloca...
6882 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6884 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6885 a SCM boolean, not a C boolean.
6887 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6889 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6890 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6891 rules for raising scm_mtrigger. Previously, unfortunate but not
6892 unlikely circumstances could result in almost constant invokation
6893 of the gc. Now, this situations should be less likely, but they
6894 are not prevented completely.
6896 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6898 * numbers.c (scm_fuck): Procedure removed; looks like old test
6900 * numbers.h: Prototype removed.
6902 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6904 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6905 array to a pointer, to match my Nov 21 change in eval.c.
6907 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6909 * libguile.h: Added #include "libguile/backtrace.h", #include
6910 "libguile/stacks.h".
6912 * strings.c (scm_string scm_make_string scm_string_ref
6913 scm_string_set_x scm_string_equal_p scm_string_append):
6914 Bugfix according to scm patch from Aubrey Jaffer:
6915 Corrected long-standing
6916 (not (eqv? (integer->char 128)
6917 (string-ref (make-string 1 (integer->char 128)) 0)))
6918 bug found by John Kozak <jk@noontide.demon.co.uk>.
6920 * strports.c, strports.h: Make scm_eval_0str return the value of
6921 the last expression evaluated (previously, it returned void).
6923 * strports.c, strports.h: New function: scm_read_0str. Does what
6926 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6928 * simpos.c (scm_getenv): return #f if string can't be found in the
6929 environment instead of throwing an exception, for compatibility
6930 with numerous other systems.
6932 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6934 * Makefile.am (.c.x): Use guile-snarf.
6935 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6937 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6939 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6941 * backtrace.c (scm_display_error_message): Made non-static, and
6942 renamed from display_error_message.
6943 * backtrace.h (scm_display_error_message): Added extern decl.
6944 * throw.c (uncaught_throw): Use it to display the error message.
6946 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6948 * inet_aton.c: Use #if 0, not #ifdef 0.
6950 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6952 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6953 to convert the returned value.
6954 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6955 the offset argument.
6957 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6959 Add new interface to catch/throw, usable from C as well as
6961 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6962 (scm_internal_catch): New function, replaces...
6963 (scm_catch_apply): Deleted.
6964 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6965 mechanism which is a bit more code, but can be used nicely from C
6966 and implement the Scheme semantics as well.
6967 (scm_internal_catch): This is the replacement; it's named after
6968 the analogous function in Emacs.
6969 (scm_catch): Reimplemented in terms of the above.
6970 (struct catch_body_data, catch_body, catch_handler): New
6971 functions, used by scm_catch.
6972 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6973 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6974 support for new cwdr.
6976 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6979 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6981 * acconfig.h: Added DYNAMIC_LINKING symbol.
6982 * configure.in: Add option and checks for dynamic linking.
6983 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6984 dynl.h: New files for dynamic linking support.
6985 * Makefile.am (libguile_a_SOURCES):
6987 (modinclude_HEADERS): Added "dynl.h".
6988 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6990 * init.c (scm_boot_guile_1): Call
6991 scm_init_dynamic_linking to initialize dynamic linking support.
6993 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6995 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6996 (as we Schemers say). It needs to be global, so that I can tweak
6997 it for the proper operation of unexec.
6998 (scm_boot_guile_1_live): New variable, see above.
7000 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
7002 * guile-snarf.sh: Removed.
7003 * PLUGIN/guile.libs: Added dependency for -lm.
7004 * acinclude.m4: Renamed from aclocal.m4.
7005 * PLUGIN/greet: Removed.
7006 * Makefile.am, aclocal.m4: New files.
7007 * configure.in: Updated for Automake.
7009 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
7011 * eval.c (scm_definedp): Use top_level_lookup_closure_var
7012 and not top_level_lookup_thunk_var.
7014 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
7016 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
7018 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
7020 * eval.c (scm_definedp): Incompatibly changed to be a builtin
7021 Scheme function, instead of syntax. Single argument is now a
7024 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7026 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
7027 scm_ra_divide): Properly terminate statements passed as arguments
7028 to IVDEP macros. (Thanks to Bernard Urban.)
7030 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
7031 with non-constant sizes. (Thanks to Bernard Urban.)
7033 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7035 It's an "eval closure", not an "eval thunk." A thunk is a
7036 function of no arguments.
7037 * root.h (struct scm_root_state): Renamed
7038 top_level_lookup_closure_var from top_level_lookup_thunk_var.
7039 (scm_top_level_lookup_closure_var): Renamed from
7040 scm_top_level_lookup_thunk_var.
7041 * root.c (mark_root): Uses changed.
7042 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
7043 * init.c (scm_start_stack): Uses changed.
7044 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
7045 Change scheme-visible name to *top-level-lookup-closure* from
7046 *top-level-lookup-thunk*.
7048 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
7050 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
7051 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
7053 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
7055 * gc.c (struct scm_heap_seg_data): Doc fixes.
7057 * gc.c (scm_gc_sweep): Empty all segments' freelists before
7058 sweeping. Then, prepend each segment's free cells to its
7059 freelist, rather than wiping out the old value. (Thanks to Marius
7062 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
7063 scm_check_freelist, scm_debug_newcell): New functions and
7064 variables, for debugging freelist problems.
7065 * pairs.h (SCM_NEWCELL): New debugging version added.
7066 * gc.h (scm_debug_newcell): Added extern declaration, used by
7067 debugging version of SCM_NEWCELL.
7069 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7071 On some systems <libc.h> conflicts with <unistd.h>, and should not
7072 be #included at all.
7073 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
7074 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
7075 * configure.in: Call it.
7076 * posix.c, filesys.c: Use its results to decide whether or not to
7078 * configure, scmconfig.h.in: Rebuilt with autoconf and
7081 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7083 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
7084 pointer to the stdio stream before calling scm_setbuf0, so the
7085 latter will be able to retrieve it. I'm surprised this didn't
7086 segfault earlier. (Thanks to Christopher Lee.)
7088 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7090 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
7093 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7095 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
7096 number of stack narrowing specifier pairs. The first specifier in
7097 a pair controls inner border, the second the outer border. A
7098 number means cut that number of frames, a procedure object means
7099 cut until that object is found in operator position in a frame.
7101 * root.c (cwdr): Bugfix.
7103 * read.c: Recording of positions disabled by default.
7105 * procs.c (scm_closure_p): New function.
7107 * posix.c (scm_tmpnam): New function.
7109 * load.c: Added #include "throw.h".
7110 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
7113 * load.c, load.h (scm_read_and_eval_x): New function.
7115 * eval.c: Renamed debug option "deval" to "debug".
7117 (scm_eval_x): `eval!' is no longer accessible from the scheme
7118 level. Motivation: We can't allow operations which introduce
7119 glocs into the scheme level. Guile's type system can't handle
7120 these as data. Use `eval' or `read-and-eval!' as replacement.
7122 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
7123 SCM_CONSP since this is a macro!; Set vframe.prev to
7124 scm_last_debug_frame instead of 0. In this way we can look
7125 "above" the virtual start stack frame if we wish.
7126 (scm_debug_hang): New function: Useful for debugging Guile in
7127 certain tricky situations. Will probably be removed later...
7129 * debug.h: Changed semantics of debug option "backtrace". This
7130 option now only indicates whether we want automatic backtrace at
7133 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7135 * ports.c: #include "filesys.h"
7136 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
7138 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
7139 Motivation: This is system specific code which is related to file
7140 I/O. It also may use select. Added code by Gary Houston to
7141 detect presence of character in stdio buffers.
7143 * libguile.h: #include "libguile/libpath.h"
7145 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
7146 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
7147 SCM_SITE_DIR; Install libpath.h among the other include files.
7149 * load.c, load.h (scm_sys_package_data_dir): New function.
7151 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7153 * stacks.h: Bugfix: Don't use tail-array length field as stack
7154 length field! This screwed GC.
7156 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7158 * _scm.h: Added #ifndef around definition of macros min and max.
7160 * __scm.h: Added hooks for threads to plugin to in ints protection
7161 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
7162 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
7163 the main code in these macros duplicated and spread over multiple
7164 files. Renamed SCM_THREADS_SWITCHING_CODE ->
7165 SCM_THREAD_SWITCHING_CODE.
7167 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
7169 * snarf.h: New file.
7170 * guile-snarf.sh: New file.
7171 * Makefile.in (inner_h_files): Added snarf.h
7172 (ancillary, install, uninstall, distclean): Added actions for
7174 (.c.x): Use guile-snarf.
7175 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
7176 (gen_c_files): Note that these depend on guile-snarf.
7177 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
7178 now in "snarf.h". Added #include "snarf.h" to get them.
7179 * libguile.h: Added #include "snarf.h".
7180 (Patches applied and tweaked by Jim Blandy.)
7182 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7184 * socket.c: Use K&R style declaration for 'close'; the GNU coding
7185 standards suggest against providing prototypes for system
7186 functions. Thanks to Greg Troxel.
7188 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
7190 * strports.c (scm_eval_0str): New function.
7191 #include "read.h", to get prototype for scm_read.
7192 * Makefile.in (strports.o): Update dependencies.
7193 * strports.h: New prototype.
7195 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
7196 scheme name from "int?" to "integer?". It seems to do the job.
7197 * numbers.h: Rename prototype too.
7198 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
7201 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
7202 scm_num_eq_p): Rename these according to R4RS conventions: call
7203 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
7204 to making libguile R4RS compliant without ice-9...
7206 * load.c (scm_sys_search_load_path): Search for files under all
7207 extensions listed in the %load-extensions variable. If FILENAME
7208 is absolute, return it unchanged, without searching the load path.
7209 (scm_loc_load_extensions): New variable, pointing to
7210 %load-extensions' value cell.
7211 (scm_init_load): Initialize it, and the value it points to.
7212 (scm_primitive_load_path): Improve error reporting.
7214 * load.c (scm_loc_load_hook): New variable, pointing to value cell
7215 of new Scheme variable %load-hook.
7216 (scm_primitive_load): Apply %load-hook to filename.
7218 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
7220 * configure.in: add tests for figuring out whether buffered data
7221 is available in a FILE structure, which is needed by char-ready.
7223 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
7226 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
7227 exceptions using misc_error instead of syserror. It seems a bit
7228 odd to throw an exception if a string can't be found in the
7229 environment, but it's consistent with open-file, stat etc.
7230 (simpos.h): remove sys_ from getenv.
7232 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
7233 occurs, throw an error instead of returning errno. Return value
7235 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
7237 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
7239 * filesys.c (scm_stat2scm): derive file type and permissions from
7240 the stat mode and append them to the returned vector.
7241 There isn't much overhead in doing this and it avoids the need to
7242 work with S_IRUSR et al. in Scheme.
7243 Define symbols scm_sym_regular etc.
7244 (scm_init_filesys): don't intern S_IRUSR etc.
7246 * load.c: change s_try_load and s_try_load_path to s_primitive_load
7247 and s_primitive_load_path.
7249 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
7251 * error.h: don't declare error symbols. prototype for scm_misc_error.
7253 * stackchk.c (scm_stack_overflow_key): defined here instead of in
7256 * error.c: use SCM_SYMBOL to set up error keys.
7257 scm_misc_error: new procedure.
7259 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7261 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
7262 between `#!' and `!#' is ignored.
7263 (skip_scsh_block_comment): New function.
7265 * feature.c (scm_set_program_arguments): New argument, FIRST.
7266 * feature.h: Update prototype.
7267 * init.c (scm_boot_guile_1): Pass new argument to
7268 scm_set_program_arguments.
7270 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7272 * init.c (scm_start_stack): Don't initialize scm_progargs here.
7273 (scm_boot_guile): Call scm_set_program_arguments here, later than
7274 the old initialization.
7276 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
7277 initialization procedure.
7278 - Delete in, out, err arguments; there are other perfectly good
7279 ways to override these when desired.
7280 - Delete result argument; this function shouldn't ever return.
7281 - Rename init_func argument to main_func, for less confusion.
7282 - Delete boot_cmd argument; main_func is more general.
7283 -Add 'closure' argument, to help people pass data to main_func
7284 without resorting to global variables.
7285 - Abort if reentered; don't bother returning an error code.
7286 - Call scm_init_standard_ports to set up the default/current
7287 standard ports; no need to pass them to scm_start_stack.
7288 - Remove code to evaluate the boot_cmd, and start the repl; let
7289 the user do something like that in main_func if they want.
7290 - Remove code to package up a return value; main_func can do any
7292 - Call exit (0), instead of returning.
7293 (scm_start_stack): Don't initialize the I/O ports here; that's
7294 weird. Delete in, out, err arguments. Move guts to
7295 scm_init_standard_ports, scm_stdio_to_port.
7296 (scm_init_standard_ports): New function, to set up current and
7297 default standard ports.
7298 (scm_start_stack, scm_restart_stack): Make these static.
7299 * init.h (scm_boot_guile): Adjust declaration.
7300 (scm_start_stack, scm_restart_stack): Remove externally
7301 visible declarations for these.
7302 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
7304 * fports.c (scm_stdio_to_port): New function. Its guts used to be
7305 written out several times in scm_start_stack.
7306 * fports.h: New declaration for the above.
7308 * feature.c (scm_set_program_arguments): New function.
7309 * feature.h: New declaration for the above.
7311 * ports.c: Formatting tweak.
7313 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
7315 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
7316 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
7317 for obtaining the address of a car or cdr field. Motivation:
7318 &SCM_CXR make assumptions about the internal structure of the
7321 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
7322 Motivation: see SCM_CXRLOC.
7324 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
7325 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
7326 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
7327 Motivation: Safer use. Some other macros are defined in terms of
7328 these operations. If these are defined using the SCM_SETCXR
7329 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
7330 to inefficiency and an <e1> with side-effects could potentially
7331 break. Also, these particular operations are heavily utilized in
7332 the garbage collector. In unoptimized code there will be a
7335 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
7336 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
7337 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
7338 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
7339 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
7340 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
7341 vports.c: Cleaned up use of pairs: Don't make any special
7342 assumptions about the internal structure of selectors and
7343 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
7344 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
7345 (Among other things, this change makes it easier to build Guile
7346 with certain compilers which have problems with casted lvalues.)
7348 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7350 * stacks.c: Improve selection of relevant stack frames when making
7351 a stack object. Introduce one level of indirection in the stack
7352 object to make it possible to "narrow" to a certain region of the
7353 stack. This facilitates making use of more clever algorithms (not
7354 implemented) for selecting relevant frames and gives a cleaner
7355 design since selection of frames can be done independently of
7356 extraction of frames from the real stack.
7357 (scm_stack_id): Also take #t as argument which means look at
7360 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
7361 Turn n_tail into an integer directly representing current number
7362 of frames in stack. Add field tail.
7364 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
7366 * debug.c (scm_make_memoized): Made it available at scheme level.
7367 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
7368 SCM_NIMP before applying heavier predicates in argument checking.
7369 (scm_local_eval): Also take memoized object as argument.
7371 * backtrace.c (scm_display_error): Just a safety measure: Stacks
7372 aren't created with zero length, but should such a strange
7373 creature suddenly turn up...
7375 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
7377 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
7378 `del', for the sake of C++ compilers. (Patch applied by JimB.)
7380 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
7382 * variable.c (scm_make_variable): Make the name hint optional, as
7384 (anonymous_variable_sym): Renamed from variable_sym. All uses
7387 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7388 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7389 of scm_primitive_load_path was also changed to
7390 "primitive-load-path", from "%try-load-path". Callers changed.
7391 We'd like to respect the convention that a function named
7392 "try-mumble" should behave just like the function called "mumble",
7393 but return #f instead of signalling some error.
7394 * load.h: Rename prototypes.
7396 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7398 * print.c (make_print_state, grow_print_state), print.h: Modified
7399 the print state representation: Don't use a tail array for
7400 recording of circular references. Resizing of the print state
7401 structure invalidates the print state pointer. To avoid passing
7402 around an indirect print state reference to all printing
7403 functions, we instead let the print state reference a resizable
7406 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7408 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7409 Don't crash when passed an improper list terminated by a
7410 non-immediate value.
7412 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7414 Allocate data for structures on an eight-byte boundary, as
7415 required by the tagging system.
7416 * struct.c (alloc_struct): New function.
7417 (scm_make_struct, scm_make_vtable_vtable): Call it.
7418 * struct.h (scm_struct_n_extra_words): Bump to 3.
7419 (scm_struct_i_ptr): New "field".
7420 * gc.c (scm_gc_sweep): When we need to free the data, use the
7421 information stored by alloc_struct to find the beginning of the
7422 block allocated to the structure, so we can free it.
7424 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7426 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7429 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7430 (scm_debug_info): New member: id.
7432 * stacks.c: Stacks are now represented as structs; Stacks have an
7433 id given to them by `start-stack'.
7434 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7436 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7437 Changed stack representation.
7439 * debug.c (scm_procedure_name): Try procedure property `name' for
7440 compiled closures aswell.
7442 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7444 * eval.c: scm_i_name moved to gsubr.c
7445 (scm_m_define): Record names of all kinds of procedure
7446 objects. (Earlier, only closures were recorded.)
7448 * procprop.h: Added declaration of scm_i_name.
7450 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7451 (scm_make_gsubr): Record names of compiled closures.
7453 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7455 * debug.c, debug.h: Removed obsolete code.
7457 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7458 stacks.c: Renamed regs --> scm_contregs.
7460 * print.c (scm_free_print_state): Cleanup print state before
7461 returning it to pool. It is better to do it here than in
7462 scm_prin1 since scm_prin1 is called often.
7464 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7465 s_set_source_property_x): Check that first argument is a pair or a
7468 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7469 scm_i_line, scm_i_column and scm_i_breakpoint global.
7471 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7472 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7475 * debug.h: Added debug object smob declaration and macro
7478 * configure.in: Build with backtrace.o and stacks.o if debug
7481 * Makefile.in: Added entries for new files: backtrace.c,
7482 backtrace.h, stacks.c and stacks.h.
7484 * symbols.c (scm_sym2ovcell): Fixed documentation.
7486 * _scm.h (min, max): Added.
7488 * async.c: Moved `min' macro to _scm.h.
7490 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7491 SCM_BACKTRACE_INDENT.
7493 * eval.c: Added new debug options `maxdepth' and `indent'.
7495 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7497 * print.h: Added selector SCM_PRINT_STATE.
7499 * print.c: New functions: scm_make_print_state,
7500 scm_free_print_state.
7502 * print.h: Added declarations for scm_make_print_state,
7503 scm_free_print_state.
7505 * debug.c (scm_m_start_stack): New acro.
7507 * debug.h: Small cleanup.
7509 * init.c (scm_boot_guile_1): Moved scm_init_debug below
7512 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

7532 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
7533 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
7534 declare functions with prototypes. (Patch thanks to Marius
7537 More prototype-related changes from Marius Vollmer:
7538 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7539 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7540 * ports.h (ptobfuns): Added prototypes. This means some casting in
7542 * fports.c: Added casts for initializations, since the functions
7543 are defined to take FILE * as their stream argument, not SCM.
7544 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7545 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7546 to `char *str_data' to conform to prototype.
7548 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7550 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7552 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7554 * stime.c, stime.h: use SCM_P method.
7556 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7558 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7559 be given at least two arguments. Insist that lst's last element
7560 be a list, but don't make any requirements of its predecessors.
7562 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7564 * eval.c (scm_nconc2last): Revert last change; there seems to be
7565 other stuff going on here.
7567 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7569 * eval.c (scm_nconc2last): Make sure that each element of lst
7570 (which is a list of argument lists, except for the tail) is a
7571 proper list, i.e., finite and terminated by '().
7573 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7575 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7578 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7579 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7582 * vectors.c (scm_make_vector): Fill vectors with the undefined
7583 value, to help make Guile Scheme code more portable to other
7586 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7587 * symbols.h, tags.h: Doc fixes.
7589 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7591 * async.c (scm_take_signal): Doc fixes.
7593 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7595 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7596 want to subtract it from the modulus; we just want to leave it
7599 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7601 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7604 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7606 * throw.c (scm_catch_apply): Finished implementation of
7609 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7611 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7613 (scm_init_filesys): set "i/o-extensions" feature.
7616 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7618 * Makefile.in (root.o): Correct dependencies.
7620 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7622 * Makefile.in: Added dependency entry for root.o.
7624 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7625 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7627 * init.c (scm_start_stack): Set initial root continuation number
7630 * procs.c: New function: scm_thunk_p.
7632 * procs.h: Added declarations of scm_thunk_p.
7634 * root.c: Renamed `call-with-new-root' -->
7635 `call-with-dynamic-root'.
7636 (cwdr): Removed allocation of new root state. This should be done
7637 separately by use of scm_make_root.
7638 (scm_apply_with_dynamic_root): New function: Does what it
7639 sounds like. Needed when spawning threads.
7641 * root.h: Added member last_debug_frame to root state.
7642 Added #include "libguile/debug.h"
7644 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7645 arguments. The motivation is that code in root.c needs catch
7646 functionality, and we want to avoid code duplication.
7647 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7648 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7649 handlers that run without popping the stack into the dynwind
7652 * throw.h: Added prototypes for scm_catch_apply and
7655 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7657 * root.h (scm_root, scm_set_root): Decouple thread support details
7658 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7659 SCM_SET_THREAD_LOCAL_DATA.
7661 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7662 and tortoise scanning loop.
7664 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7666 * Makefile.in: Rebuild dependencies.
7668 * libguile.h: #include "libguile/print.h" before "smob.h", since
7669 the latter uses the print_state structure.
7671 * throw.c (scm_ithrow): Use the correct variable when checking to
7672 see if a given element of scm_dynwinds is a valid catch.
7674 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7675 structure, abort; don't just silently ignore the garbage.
7677 * _scm.h: #include "print.h" here, since it seems to be used just
7679 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7680 strports.c, unif.h: Don't #include "print.h".
7682 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7684 * feature.h (scm_loc_features): Removed external declaration.
7685 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7687 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7689 * feature.c (scm_init_feature): Added threads feature (needs to be
7690 initialized here, since features doesn't exist when
7691 scm_init_threads is called).
7693 * libguile.h: Added #include "libguile/../threads/threads.h".
7694 (This is a kludge to get thread support working. This should be
7697 * configure.in, acconfig.h: Added flags for thread support.
7699 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7702 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7703 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7706 * _scm.h: Added conditional #include "threads.h"
7708 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7709 SCM_THREADS_SWITCHING_CODE.
7711 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7712 allocate the basic dynamic root object.
7713 (scm_boot_guile): Added call to scm_init_root.
7715 * root.c, root.h: Added root smob.
7716 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7717 functions: Implements dynamic roots mostly according to spec in
7718 SCM manual. Main difference is that the second argument is a
7719 throw handler rather than an error "thunk".
7721 * root.h: Added declaration of scm_init_root.
7723 * root.c: Added #include "genio.h", #include "smob.h", #include
7724 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7726 (scm_init_root): Added #include "root.x".
7728 * throw.c: Added #include "stackchk.h"
7729 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7730 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7731 can be used in scm_call_with_new_root; Added reenabling of stack
7732 checking when catching a throw.
7734 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7736 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7738 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7739 element is not found, as per R4RS.
7741 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7743 * list.c: Doc fixes throughout.
7745 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7747 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7748 declare the char * to be const. Avoids a warning in rgx.c.
7750 * ports.h: spelling fix.
7752 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7755 * load.c (scm_sys_try_load_path): throw an error if file not found
7756 (like it says it in NEWS).
7758 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7760 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7761 PROPS slot to '(), not #f; it's an empty alist.
7763 * throw.h, throw.c: Use SCM_P instead of #if hair.
7765 Remove special support for uncaught throws; see throw.c for
7767 * throw.c (uncaught_throw): New function.
7768 (scm_ithrow): Call uncaught_throw if we don't find a throw
7769 target; don't mess with scm_bad_throw_vcell.
7770 (scm_bad_throw_vcell): Variable deleted.
7771 (scm_init_throw): Don't initialize it.
7773 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7776 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7778 * numbers.c (scm_istr2int): If the number is short (as most
7779 numbers are), just call scm_small_istr2int to deal with it.
7780 (scm_small_istr2int): New function, created by un-#ifdefing the
7781 non-bignum version of scm_istr2int and renaming it.
7783 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7785 * load.c (scm_sys_try_load): don't check whether value returned
7786 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7787 Change the Scheme name from %try-load to primitive-load.
7789 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7790 Can avoid passing a message, allowing it to be derived in the
7791 error handler (e.g., if we want to throw to the key both from
7794 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7796 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7797 references now have a new appearance which is more compact and
7798 also gives a clue about what the target of the reference is.
7799 By setting parameters in the print state, more fancy printing can
7800 be achieved. This is used by the (not yet commited) backtrace
7803 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7805 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7808 * print.c: Added #include "struct.h". Removed function
7811 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7812 scm_iprin1. Removed prototype for scm_prlist.
7814 * arbiters.c (prinarb),
7815 async.c (print_async),
7816 debug.c (prindebugobj, prinmemoized),
7817 eval.c (prinprom, prinmacro),
7818 filesys.c (scm_fd_print, scm_dir_print),
7820 mallocs.c (prinmalloc),
7821 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7822 smob.h (scm_smobfuns),
7823 srcprop.c (prinsrcprops),
7825 unif.c, unif.h (scm_raprin1, rapr1),
7826 variable.c (prin_var): Changed argument `int writing' to
7827 `scm_print_state *pstate'.
7829 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7830 that it will be called before scm_init_print.
7832 * print.c (scm_prin1): Print states are now allocated when calling
7833 scm_prin1 and then passed around to all printing functions as an
7834 argument. A cache `print_state_pool' enables reuse of print
7836 (scm_make_print_state): New function.
7837 (scm_iprin1): Adaption to print states.
7838 (scm_iprlist): An initial "hare and tortoise" scan brings down
7839 time complexity to O (depth * N). (Better time complexity will be
7840 achieved when the printing code is completely rewritten.)
7842 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7844 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7845 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7846 it gets done whether or not the cache variable has a value.
7848 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7850 Distinguish #f and ().
7851 * __scm.h: #undef SICP.
7852 * pairs.h (SCM_EOL): Delete this definition, equating it with
7854 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7855 the value it used to have. Doc fixes, too.
7857 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7859 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7860 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7861 Lord's implementation of structs, allowing for tail arrays as
7862 described in the manual. Also fixed some bugs. (Both the interface
7863 and the implementation should be improved.)
7865 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7867 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7868 People who whish to see the source can do `(print-enable 'source)'.
7869 Removed #ifdef DEBUG_EXTENSIONS.
7871 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7873 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7874 integer (assuming for now accepting an integer is a good thing).
7876 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7877 %S will be used instead for write'ing arguments.
7879 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7880 asserts. fix a few other asserts.
7881 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7882 scm_uniform_vector_ref, scm_array_set_x,
7883 scm_dimensions_to_unform_array): change args in
7884 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7885 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7886 scm_substring_fill_x): likewise.
7887 gsubr.c (scm_gsubr_apply): likewise.
7888 eval.c (SCM_APPLY): likewise.
7890 * eval.c (4 places): replace scm_everr with lgh_error or
7893 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7894 scm_memory_error): new procedures.
7895 scm_everr: deleted. can use scm_wta, dropping first two args.
7896 scm_error: convert NULL subr to SCM_BOOL_F.
7898 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7901 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7904 * error.c, error.h: new error keys: scm_arg_type_key,
7905 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7907 scm_wta: reimplement using lgh_error instead of scm_everr.
7909 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7911 * gdbint.c: scm_lread now has one more argument.
7913 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7914 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7915 loading source from non-file ports, which, e. g., happens when
7916 using the Emacs interface).
7918 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7921 * read.c: Added code for recording of positions of source code
7922 expressions; New functions: recsexpr, scm_lreadrecparen;
7923 _scm_make_srcprops --> scm_make_srcprops
7924 (scm_flush_ws): Removed updating of positions counters. This work
7925 is already done by scm_gen_getc
7927 * read.h: Added prototype for scm_lreadrecparen
7929 * print.c: Added #include "alist.h"
7931 * eval.c: Added #include "hash.h"
7933 * eq.c: Added #include "ramap.h"
7935 * options.c: Documentation fixes.
7937 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7938 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7939 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7940 --> scm_make_srcprops
7942 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7943 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7944 function calls in the definition of the whash access macros.
7946 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7948 * init.c (scm_boot_guile): Add level of indirection to
7949 scm_boot_guile_1() to ensure that stack base pointer is properly
7950 initialized. There was no guarantee that variable i was the
7951 highest/lowest variable on stack (i.e. the call frame of
7952 scm_boot_guile was not completely protected from gc).
7954 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7956 * ports.h (scm_port_table): put back file_name, it will be used to
7957 support debugging. Undo related changes in fports.c, ioext.c,
7960 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7962 * ports.h (scm_port_table): remove file_name member for now, it seems
7964 * fports.c (scm_open_file): don't set file_name in PTAB.
7965 (prinfport): don't use file_name in PTAB.
7966 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7967 * ports.c (scm_add_to_port_table): don't intialize file_name.
7968 (scm_port_file_name): remove for now.
7969 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7971 * fports.h (scm_mkfile): prototype deleted.
7972 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7974 * debug.c, unif.c: use scm_out_of_range instead of
7975 wta for range errors (ASSERT still needs work).
7977 * error.c, error.h (scm_out_of_range): new procedure.
7979 * error.c, error.h (scm_out_of_range_key): new key.
7981 * posix.c (scm_sync): #else was missing.
7983 * error.c, error.h: append _key to names scm_num_overflow and
7986 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7987 of consing an empty list.
7988 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7989 of macros, saves code and string space.
7990 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7991 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7992 lower case. Rename scm_syserror_m to scm_syserror_msg.
7993 error.h: prototypes for new procedures.
7995 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7997 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7999 * error.c, error.h: setup scm_num_overflow key.
8001 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
8002 Remove definition of SCM_OVSCM_FLOW.
8004 * fports.c (scm_open_file): use SCM_SYSERROR_M.
8006 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
8007 explicit message and args.
8009 * error.c, error.h, __scm.h: change system_error_sym to
8012 * error.c (system_error_sym): remove leading %% from the Scheme name
8015 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
8017 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8019 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
8020 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
8021 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
8022 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
8023 renamed. (These were introduced by unsupervised name
8026 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8028 * print.c: Added code for detection of circular references during
8029 printing. (init_ref_stack, grow_ref_stack): New functions. Added
8030 a hook for printing of closures (accessible via print options).
8031 This leads to a split of calls to scm_iprin1 into two classes:
8032 elementary print operations (e. g. the code which prints a smob)
8033 still use scm_iprin1 while top level calls (like scm_display) use
8034 scm_prin1. scm_prin1 begins by clearing the data structure used
8035 to record reference information.
8037 * print.h: Added declarations of scm_prin1 and scm_prlist.
8039 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
8041 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
8043 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
8045 * error.c (err_head): scm_iprin1 --> scm_prin1
8047 * debug.c: Adjusted header comment.
8051 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
8053 * strerror.c: Doc fix.
8055 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8057 * gdbint.c (gdb_read): Now possible to run during GC.
8058 (unmark_port, remark_port): New functions.
8060 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
8062 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
8063 of allocating a new string object. Also, increase size by
8064 the factor 2 instead of 1.5.
8066 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
8068 * __scm.h (SCM_P): Corrected to run under traditional C.
8070 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
8073 * async.c: Calls to scm_sysintern corrected.
8075 * async.h (scm_async_clock): Redundant declaration removed.
8077 * continuations.c (scm_dynthrow): Redundant declaration removed.
8079 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
8080 Definition typos corrected.
8082 * debug.h: Missing declarations of functions in debug.c added
8085 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
8086 Missing declarations to functions in eval.c added.
8088 * filesys.c: Possibly uninitialized variable rv.
8090 * gc.h (scm_object_addr, scm_unhash_name): Missing
8091 declarations of functions defined in gc.c added.
8093 * genio.c: Possible typos str_data -> wstr_data. ???
8095 * genio.c: Possibly unintended shadowing of local variable
8096 `int c' (gotos out of scope of inner `c'). ???
8098 * init.c: Uninitialized `SCM last' may be used.
8100 * ioext.h: (scm_sys_isatty_p): Typo.
8102 * list.h (scm_list_head): Missing prototype for function in
8105 * numbers.c (scm_two_doubles): Changed from extern to static
8106 (is used only within numbers.c).
8108 * numbers.h: Repeated declarations removed.
8110 * ports.h (scm_close_all_ports_except): Declaration for the
8111 function defined in ports.c added.
8113 * posix.h: Missing declarations added.
8115 * procs.h (scm_make_subr_opt): Missing declaration added.
8117 * socket.h (scm_sys_gethost): Missing declaration added.
8119 * socket.h: Redundant declarations removed (they are in fdsocket.h).
8121 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
8122 Missing declarations added.
8124 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
8126 * struct.c: Uninitialized variable `SCM answer' may be used.
8128 * unif.c (l2ra): Declaration prototype.
8130 * unif.c (scm_array_equal_p): Dummy definition removed (it is
8131 defined in ramap.c).
8133 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
8134 Redundant declarations removed (they are in ramap.h).
8136 * variable.h (scm_make_udvariable,
8137 scm_make_undefined_variable): Declaration corrected to
8138 correspond variable.c.
8140 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
8141 Missing declarations added.
8143 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
8145 * Makefile.in (distclean): Don't forget to delete fd.h.
8147 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
8149 * fd.h.in, tags.h: Trivial cleanups.
8151 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
8152 marksweep.h just declared functions from gc.c.
8153 * gc.h, libguile.h: Don't #include "marksweep.h".
8154 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8155 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
8156 dependencies updated.
8158 * libguile.h: Don't #include "files.h"; it's been deleted.
8160 * files.c (scm_sys_delete_file): Moved to filesys.c.
8161 File is now empty; deleted.
8163 * filesys.c: scm_sys_delete_file is now here. Remove
8164 #if's; they seem to rely on remnants of an old portability
8165 regimen. If the problems come up again, solve them properly,
8166 using autoconf. Specifically: Don't test M_SYSV, and #define
8167 remove to be unlink if it's #defined; don't use remove just
8168 because HAVE_STDC_HEADERS is #defined.
8169 * filesys.h: Add declarations for scm_sys_delete_file.
8170 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8171 files.o, files.h, files.c, and files.x.
8172 * init.c: Don't #include "files.h", and don't call scm_init_files.
8174 Use SCM_P instead of PROTO; the latter intrudes on the user's
8176 * params.h: Deleted; definition of SCM_P moved to...
8177 * __scm.h: ... here, where it replaces PROTO macro.
8178 * libguile.h, smob.h: Don't #include "params.h".
8179 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
8180 smob.h: Fix prototypes accordingly.
8181 * Makefile.in: Update dependencies.
8182 (inner_h_files): Remove params.h.
8184 * gc.c: #include "gc.h"; every module should include its header,
8185 to let the compiler cross-check the declarations against the
8188 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
8189 simpos.h: #include "libguile/__scm.h".
8191 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
8193 * init.c: Don't forget to #include smob.h and init.h.
8194 * Makefile.in: Dependencies updated.
8196 * smob.h: Use PROTO instead of #if __STDC__.
8198 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
8200 * __scm.h: Doc fixes.
8202 * __scm.h, libguile.h: Use "quotes" in the #includes, not
8203 <angles>; this allows `make depends' to work properly.
8205 * libguile.h: #include smob.h and pairs.h before the others; they
8206 define typedefs used by other headers.
8208 C files should #include only the header files they need, not
8209 libguile.h (which #includes all the header files); the pointless
8210 recompilation was wasting my time.
8211 * Makefile.in (all .o dependency lists): Regenerated.
8212 * libguile.h: Don't try to get a definition for size_t here...
8213 * __scm.h: Do it here.
8214 * _scm.h: Since this is the internal libguile header, put things
8215 here that all (or a majority) of the libguile files will want.
8216 Don't #include <libguile.h> here; that generates dependencies on
8217 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
8218 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
8219 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

8305 * symbols.c: Get "symbols.h", "mbstrings.h", "alist.h",
8306 "variable.h", "eval.h", "chars.h".
8307 * tag.c: Get "tag.h", "struct.h", "chars.h".
8308 * throw.c: Get "throw.h", "continuations.h", "debug.h",
8309 "dynwind.h", "eval.h", "alist.h", "smob.h", "genio.h".
8310 * unif.c: Get "unif.h", "feature.h", "strop.h", "sequences.h",
8311 "smob.h", "genio.h", "eval.h", "chars.h".
8312 * variable.c: Get "variable.h", "smob.h", "genio.h".
8313 * vectors.c: Get "vectors.h", "eq.h".
8314 * version.c: Get "version.h".
8315 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
8316 * weaks.c: Get "weaks.h".
8318 * stackchk.h: #include "libguile/debug.h",
8320 * print.h, read.h: #include "options.h", since everyone who uses
8321 either of these files will need that.
8323 * smob.h: #include "ports.h", "genio.h", and "print.h", since
8324 anyone who uses this file will need them to define the smob
8325 printing functions. Also, get markers.h, since people will need
8326 to #define the mark functions.
8328 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
8329 * ports.h: ... to here.
8331 * ports.h (scm_port_table_size): Explicitly give type as 'int';
8332 don't rely on archaic C default type rules.
8334 * fports.h: #include "libguile/ports.h", since you need that in
8335 order to parse this.
8337 * genio.h: #include "libguile/print.h", because you need that to
8338 parse this; don't bother #including "ports.h", since print.h gets
8341 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
8343 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
8344 this; it's now a reference to an element of *scm_root.
8346 * debug.h: Don't #include "options.h"; the compiler won't be able
8347 to find that once the headers are installed; instead, #include
8348 "libguile/options.h".
8349 * gc.h: Same, with marksweep.h.
8350 * mbstrings.h: Same, with symbols.h.
8351 * scmhob.h: Same, with _scm.h.
8352 * smob.h: Same, with params.h.
8354 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
8355 C files; there's no need for this, and it forces recompilations
8358 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
8360 * error.c (scm_error): declare scm_error_callback.
8362 * error.h: prototype for scm_error_callback.
8364 * __scm.h: define lgh_error.
8365 (SCM_SYSERROR): redefine using lgh_error.
8367 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
8369 * error.c (scm_error): new procedure.
8371 * error.h: prototype for scm_error.
8373 * Makefile.in (install): install scmconfig.h from the current
8374 directory, not $(srcdir).
8376 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8378 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8379 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8380 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
8381 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
8382 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
8383 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8384 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8385 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8386 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8387 vports.h, weaks.h: #include "libguile/__scm.h", not
8388 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
8389 dependencies are within libguile properly.
8391 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8393 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8394 when scmconfig.h doesn't exist.
8396 * load.c (scm_sys_try_load): Correct spelling.
8398 * feature.c (scm_loc_features): Make this static.
8400 * Makefile.in (libpath.h): Omit trailing slash from path. We
8401 shouldn't require it of users, so why put it here?
8403 Move code to initialize and search %load-path from ice-9 to C
8404 code, so we can use the load-path to find the ice-9 boot code;
8405 this makes it easier to run Guile without installing it. See
8406 corresponding changes in guile/Makefile.in.
8407 * feature.c: Move stuff concerned with the load path to load.c.
8408 (scm_compiled_library_path): Deleted.
8409 Don't #include libpath.h here.
8410 * feature.h: Don't mention scm_compiled_library_path.
8411 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8412 <sys/stat.h>, and <unistd.h> (if present).
8413 (R_OK): #define if the system hasn't deigned to.
8414 (scm_loc_load_path): New variable.
8415 (scm_init_load_path, scm_sys_search_load_path,
8416 scm_sys_try_load_path): New functions.
8417 (scm_init_load): Initialize scm_loc_load_path to point to the
8418 value cell of the Scheme %load-path variable.
8419 * load.h: Add declarations for scm_sys_search_load_path,
8420 scm_sys_try_load_path.
8421 * init.c: Call scm_init_load_path.
8422 * Makefile.in (feature.o, load.o): Dependencies updated.
8424 * load.c, load.h: Rewrite using PROTO macro.
8426 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8428 * gc.c (scm_cellp): New function: C predicate to determine if an
8429 SCM value can be regarded as a pointer to a cell on the heap.
8431 * gc.h: Added declaration of scm_cellp.
8433 * gdb_interface.h: New file: The GDB interface header from the GDB
8436 * gdbint.c: New file: GDB interface.
8438 * gdbint.h: New file: GDB interface.
8440 * libguile.h: Added #include <libguile/gdbint.h>.
8442 * init.c (scm_boot_guile): Added scm_init_gdbint.
8444 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8445 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8446 found if object files and source are kept separate).
8448 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8450 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8452 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8454 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8455 TK_SRC_DIR; they're not relevant any more.
8457 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8458 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8460 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8462 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8463 search path, so we can find the <libguile/MUMBLE.h> headers.
8465 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8467 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8468 implicit in the .c.o rule.
8469 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8472 Put the library path in a header file, instead of passing it on
8473 the command line in every compilation.
8474 * Makefile.in (libpath.h): New target.
8475 (feature.o): Depend on libpath.h.
8476 (clean): Delete libpath.h.
8477 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8478 * feature.c: ... #include "libpath.h" here.
8479 * .cvsignore: Ignore libpath.h.
8481 Don't install the unwashed masses of Guile header files in the
8482 main #include path; put most of them in a subdirectory called
8483 'libguile'. This avoids naming conflicts between Guile header
8484 files and system header files (of which there were a few).
8485 * Makefile.in (pkgincludedir): Deleted.
8486 (innerincludedir): New variable; this and $(includedir) are enough.
8487 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8488 (installed_h_files): Divide this up. Now this variable lists
8489 those header files which should go into $(includedir) (i.e. appear
8490 directly in the #include path), and ...
8491 (inner_h_files): ... this new variable says which files appear in
8492 a subdirectory, and are referred to as <libguile/mumble.h>.
8493 (h_files): List them both.
8494 (install): Create innerincludedir, not pkgincludedir. Put
8495 the installed_h_files and inner_h_files in their proper places.
8496 (uninstall): Corresponding changes.
8497 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8498 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8499 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8500 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8501 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8502 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8503 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8504 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8505 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8506 vports.h, weaks.h: Find __scm.h in its new location.
8507 * __scm.h: Find scmconfig.h and tags.h in their new locations
8508 (they're both "inner" files).
8510 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8512 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8514 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8516 * posix.c: Doc fixes.
8518 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8520 * socket.c: Don't include a prototype for inet_aton; just use a
8521 K&R style declaration, to avoid warnings but minimize the chance
8522 of conflicts with the system.
8524 On NextStep, <utime.h> doesn't define struct utime, unless we
8525 #define _POSIX_SOURCE before #including it.
8526 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8527 * acconfig.h: New comment text for above CPP symbol.
8528 * configure.in: Call it.
8529 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8531 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8533 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8534 testing for __EMX__.
8536 * posix.c: #include <libc.h>, if it exists.
8538 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8539 don't even know if the latter exists.
8541 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8542 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8543 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8545 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8547 (scm_init_posix): Use them when initializing the Scheme constants
8550 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8552 * Makefile.in (libdir, includedir, bindir): Use the
8553 autoconf-supplied values, instead of deriving them ourselves.
8554 (pkgincludedir, datadir, pkgdatadir): New variables.
8555 (install, uninstall): Put the header files in a special
8556 subdirectory, not in the main search path.
8558 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8559 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8561 * Makefile.in (IMPLPATH): Deleted; never used.
8563 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8564 on the Tcl/Tk source any more.
8565 (INCLUDE_CFLAGS): Remove references to the above.
8567 * Makefile.in (version.o): Corrected dependencies.
8569 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8571 * libguile.h: #include "version.h"
8573 * init.c (scm_boot_guile): Call scm_init_version.
8574 * gscm.c (gscm_run_scm): Call scm_init_version.
8576 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8577 GUILE_VERSION): AC_DEFINE these.
8578 (acconfig.h): #undef the above symbols.
8580 * Makefile.in (libobjs): Add version.o.
8581 (installed_h_files): Add version.h.
8582 (c_files): Add version.c.
8583 (gen_c_files): Add version.x.
8584 (version.o): New rule.
8585 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8586 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
8587 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
8588 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
8589 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
8590 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
8591 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
8592 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
8593 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
8594 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
8595 weaks.o): Add version.h to dependency lists.
8596 (markers.o): Remove duplicate rule.
8598 * version.h: New file.
8600 * version.c: New file.
8602 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8604 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8605 array; use it appropriately. Since GCC is quite happy to
8606 subscript functions, it never warned us about this; we should use
8607 -Wpointer-arith in the future. I guess we never tested
8610 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8612 * socket.c: Doc and copyright fixes.
8614 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8616 * debug.c: Fixed and improved gdb support.
8618 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8620 * socket.c: Added declaration of inet_aton to avoid compiler
8621 warning. (Hope this solution is correct.)
8623 * stime.c: Added declaration of ftime. (This is missing in
8626 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8628 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8630 * Makefile.in (c_files): add strerror.c.
8632 * strerror.c: new file from Emacs' sysdep.c.
8633 maybe configure should also check for sys_errlist.
8635 * configure.in (AC_REPLACE_FUNCS): add strerror.
8637 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8639 * debug.c (scm_init_debug): Added initialization for
8640 scm_evaluator_traps.
8642 * debug.h, debug.c: Various name changes.
8643 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8644 "debug-options-interface". See commentary in options.c.
8646 * options.h, options.c: Options now have documentation strings.
8647 Also added a long explanatory commentary.
8649 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8652 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8653 last_debug_info_frame is now updated in all cases.
8655 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8658 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8660 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8661 Added option STACK_CHECKING.
8663 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8665 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8667 * __scm.h: Removed symbols for debugging support.
8669 * acconfig.h: Added symbols for debugging support.
8671 * configure.in: Added user option for debugging support.
8672 --enable-debug will include the debugging code into libguile.a.
8674 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8675 scm_relocate_chunk_to_heap.
8677 * debug.c: New file: low-level debugging support. It also
8678 includes support for debugging with gdb. (The extensions to gdb
8679 are written by Per Bothner at Cygnus.)
8681 * debug.h: New file: low-level debugging support.
8683 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8684 argument pairs. Extensive modifications to the debugging
8685 evaluator. Added "SECTION:" commentaries to clarify what happens
8686 when, during double compilation. Renamed EVALIMP --> EVALIM.
8687 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8688 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8689 the beginning of the file. New procedure: scm_unmemocopy.
8690 Added some global state variables needed by the debugging
8691 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8692 check_entry, check_apply, check_exit, debug_options and
8693 evaluator_traps. New acro: undefine.
8695 * eval.h: Renamed EVAL --> XEVAL.
8697 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8698 --> scm_make_weak_key_hash_table.
8700 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8701 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8703 * libguile.h: Conditionally include debug.h
8705 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8706 scm_object_properties shouldn't return handle. `handle' now gets
8707 initialized in scm_set_object_properties_x. scm_object_properties
8708 doesn't any longer create an entry in scm_object_whash.
8710 * options.c: New file: handling of run time options.
8712 * options.h: New file: handling of run time options.
8714 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
8716 * print.c: New procedure: scm_print_options
8718 * print.h: Defines for print options.
8720 * read.c: New procedure: scm_read_options
8722 * read.h: Defines for reader options.
8724 * root.h: Added scm_source_whash among scm_sys_protects.
8726 * srcprop.c: New file: source properties.
8728 * srcprop.h: New file: source properties.
8730 * throw.c (jbsmob): Jump buffers are now correctly allocated.
8731 (Bug found by A. Green.)
8733 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8735 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8737 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8739 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8741 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8742 and should be called by the final client.
8744 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8746 * gc.h: Use the PROTO macro when declaring functions.
8747 * gc.c: Use the PROTO macro when declaring static functions.
8748 Remove the CPP hair around function definitions.
8750 * gc.c (scm_init_storage): Initialize scm_asyncs.
8752 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8753 preprocessor symbol; "__scm.h" is where it might get #defined.
8754 * __scm.h: Similar: #include <scmconfig.h> before testing
8757 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8759 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8761 * init.c (scm_boot_guile): Add init_func argument; call
8762 (*init_func) instead of calling scm_appinit; it's ucky to
8763 hard-code names for the user's procedures.
8764 * init.h (scm_boot_guile): Adjust declaration.
8766 * __scm.h (PROTO): New macro, for declaring functions with
8769 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8770 eliminate all the __STDC__ conditionals.
8771 (scm_boot_guile): Add declaration.
8772 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8773 Remove __STDC__ conditionals around function definitions; the
8774 declarations in init.h will provide the same information, more
8777 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8778 complain about it in the error message; the error message is
8779 adequate without that note, and there's nothing the user can do
8782 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8784 * Makefile.in (ancillary): Drop def.sed.
8786 * posix.c (scm_init_posix): Use numeric values, rather than
8787 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8788 F_OK. The symbols aren't available on some systems, and I'm
8789 pretty sure their values are fixed by common widespread practice.
8790 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8792 More functions unavailable on some systems.
8793 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8794 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8796 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8797 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8798 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8799 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8800 stub that signals an error as the #else.
8802 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8804 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>

8842 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8843 from scm_sizet to int.
8845 * error.c: include unistd.h.
8847 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8850 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8852 * __scm.hd, def.sed: deleted.
8854 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8856 Changes for NeXT, suggested by Robert Brown.
8857 * configure.in: Call AC_TYPE_MODE_T.

8859 NeXT. Put header file list in alphabetical order.
8860 * configure, scmconfig.h.in: Regenerated.
8861 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.

8883 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8885 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8887 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8889 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8891 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8893 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8894 This is necessary on Ultrix, and doesn't hurt portability.
8896 * Makefile.in (dist-dir): New target, implementing a new dist system.
8897 (installed_h_files): Put in alphabetical order.
8898 Remove duplicate entries for markers.h and unif.h.
8899 (c_files): Remove duplicate entries for markers.c.
8900 (ancillary): Renamed from anillery; all uses changed. Remove
8901 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8902 Remove all the ../doc/* files; doc/Makefile.in handles that.
8904 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8906 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8907 every if must have an else, or else the whole command has a
8908 non-zero exit code whenever the if's condition is false.
8910 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>

8919 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8920 Remove leading % from scheme names.
8921 Do not return error values, call SCM_SYSERROR or similar.

8972 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8974 * ports.c (scm_ports_prehistory): size malloced here doesn't
8975 matter so long as it is non-0 (got rid of "* 4").
8977 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8979 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8980 since its definition was bogus).
8982 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8984 * mallocs.[ch]: back again (for rx at least).
8986 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8988 * ports.c: removed functions relating to the mapping between ports
8989 and descriptors. (That stuff is unix-specific and should be collected
8990 in a separate library).
8992 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8993 (Tom Mckay@avanticorp.com)

8997 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8998 handled correctly (SCM_FREEP was applied to them) -- test for
8999 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

9044 (possibly triggering gc) before setting the tag of the corresponding
9047 * pairs.c (scm_delq_x): never throw an error.
9049 * vectors.c (scm_make_vector): made the default vector fill argument
9050 into '() (much more useful than the previous value, "#unspecified")

9054 * ports.c (scm_add_to_port_table): Added fields
9055 to port table entries: file_name, line_num, col.
9056 Update these in open_file, gen_getc and gen_ungetc.
9057 Added procedures to access those fields.
9059 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
9061 * procs.c (scm_make_subr_opt): new entry point for making

9167 initialization to fix a race condition.
9169 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

9193 set the multi_byte flag correctly in symbols. This is wrong.
9194 intern_obbary_soft and msymbolize should take an extra parameter.
9195 Also, weird multibyte symbols don't print correctly.
9196 The weird symbol syntax is also a bit bogus (emacs doesn't quite
9199 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
9201 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means

9204 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
9206 * strings.c (scm_make_shared_substring): build'em.
9207 It might better to keep a table of these and use one

9373 * eval.c (SCM_CEVAL): if the function position evaluates
9374 to a macro, process it accordingly. (Previously, macros were
