1 1999-12-04 Gary Houston <ghouston@freewire.co.uk>
3 * ports.c (scm_port_closed_p): new procedure, implements
4 "port-closed?" suggested by Bernard Urban.
5 ports.h: added prototype, removed the SCM_P macros.
7 1999-11-30 Gary Houston <ghouston@freewire.co.uk>
9 * unif.h: added some comments, removed the SCM_P macros.
11 1999-11-29 Gary Houston <ghouston@freewire.co.uk>
13 * vports.c (sf_write): use scm_makfromstr, not scm_makfrom0str
14 (thanks to Daniel Skarda).
16 1999-11-22 Jim Blandy <jimb@savonarola.red-bean.com>
18 * gscm.c, gscm.h: Deleted. They were unused.
20 1999-11-20 Gary Houston <ghouston@freewire.co.uk>
22 * unif.c (scm_list_to_uniform_array): call
23 scm_dimensions_to_uniform_array with a third argument of
24 SCM_UNDEFINED instead of SCM_EOL.
26 1999-11-19 Gary Houston <ghouston@freewire.co.uk>
28 * the following changes allow guile to be built with the array
29 "module" omitted. some of this stuff is just tc7 type support,
30 which wouldn't be needed if uniform array types were converted
33 * tag.c (scm_utag_bvect ... scm_utag_cvect): don't define unless
35 (scm_tag): don't check array types unless HAVE_ARRAYS.
37 * sort.c (scm_restricted_vector_sort_x, scm_sorted_p):
38 remove the unused array types.
39 * (scm_stable_sort, scm_sort): don't support vectors if not
40 HAVE_ARRAYS. a bit excessive.
42 * random.c (vector_scale, vector_sum_squares,
43 scm_random_solid_sphere_x, scm_random_hollow_sphere_x,
44 scm_random_normal_vector_x): don't define unless HAVE_ARRAYS.
46 * gh_data.c (makvect, gh_chars2byvect, gh_shorts2svect,
47 gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect, gh_doubles2dvect,
48 gh_uniform_vector_length, gh_uniform_vector_ref):
49 don't define unless HAVE_ARRAYS.
50 (gh_scm2chars, gh_scm2shorts, gh_scm2longs, gh_scm2floats,
52 don't check vector types if not HAVE_ARRAYS.
54 * eq.c (scm_equal_p), eval.c (SCM_CEVAL), print.c (scm_iprin1),
55 gc.c (scm_gc_mark, scm_gc_sweep), objects.c (scm_class_of):
56 don't support the array types unless HAVE_ARRAYS is defined.
58 * tags.h: make nine tc7 types conditional on HAVE_ARRAYS.
60 * read.c (scm_lreadr): don't check for #* unless HAVE_ARRAYS is
61 defined (this should use read-hash-extend).
63 * ramap.c, unif.c: don't check whether ARRAYS is defined.
65 * vectors.c (scm_vector_set_length_x): moved here from unif.c. call
66 scm_uniform_element_size if HAVE_ARRAYS.
67 vectors.h: prototype too.
69 * unif.c (scm_uniform_element_size): new procedure.
71 * init.c (scm_boot_guile_1): don't call scm_init_ramap or
72 scm_init_unif unless HAVE_ARRAYS is defined.
74 * __scm.h: don't define ARRAYS.
76 * Makefile.am (EXTRA_libguile_la_SOURCES): unif.c and ramap.c
77 moved here from libguile_la_SOURCES.
79 1999-11-18 Gary Houston <ghouston@freewire.co.uk>
81 * socket.c (scm_htons, scm_ntohs, scm_htonl, scm_ntohl): new
82 functions for network data conversion.
84 * numbers.c (scm_num2long, scm_num2longlong):
85 throw out-of-range instead of wrong-type-arg if appropriate.
86 (scm_iint2str): handle -2^31 correctly.
87 (scm_num2long): handle -2^31 bignum correctly.
88 (scm_num2long_long): rewrite the bigdig case: basically copied
90 numbers.h: (SCM_BITSPERLONGLONG): deleted.
92 * unif.c (rapr1): use sprintf instead of intprint for unsigned
93 longs: intprint can't cope with large values.
95 * numbers.c (scm_num2ulong): check more consistently that the
96 input is not negative. if it is, throw out-of-range instead of
99 * ramap.c (scm_array_fill_int): don't limit fill to INUM for
100 uvect, ivect or llvect.
101 Check that fill doesn't overflow short uniform array.
103 * __scm.h: add another long to the definition of long_long and
106 * unif.c (scm_raprin1): use 'l' instead of "long_long" in the
107 print representation of llvect. read can't handle more than
109 (scm_dimensions_to_uniform_array): make "fill" an optional argument
110 instead of a rest argument.
112 * tags.h (scm_tc7_llvect): wasn't defined anywhere, so use the free
115 * __scm.h: don't mention LONGLONGS.
117 * unif.c, numbers.c, eq.c, gc.c, print.c, eval.c, ramap.c:
118 replace LONGLONGS with HAVE_LONG_LONGS as set by configure.
120 1999-11-17 Gary Houston <ghouston@freewire.co.uk>
122 * net_db.c (scm_inet_aton): throw errors using the misc-error key
123 instead of system-error. inet_aton doesn't set errno.
124 system-error isn't right in gethost either, since it's throwing
125 the value of h_errno instead of errno. so:
126 (scm_host_not_found_key, scm_try_again_key,
127 scm_no_recovery_key, scm_no_data_key): new error keys.
128 (scm_resolv_error): new procedure, use the new keys.
129 (scm_gethost): call scm_resolv_error not scm_syserror_msg.
131 1999-11-16 Gary Houston <ghouston@freewire.co.uk>
133 * error.c: (various): use scm_cons instead of scm_listify
134 to build short lists.
136 1999-11-03 Gary Houston <ghouston@freewire.co.uk>
138 * socket.c (scm_fill_sockaddr): zero the address structure before
139 use, in case it has a sin_len field and the OS doesn't like random
140 values (thanks to Bertrand Petit).
142 1999-10-26 Mark Galassi <rosalia@lanl.gov>
144 * gh.h, gh_data.c (gh_symbol2scm): changed gh_symbol2scm() to take
145 a const char * argument, upon suggestion from Lynn Winebarger.
147 1999-10-26 Gary Houston <ghouston@freewire.co.uk>
149 * strports.c (st_end_input): avoid dubious pointer arithmetic.
151 1999-10-24 Gary Houston <ghouston@freewire.co.uk>
153 * Move the responsibility for resetting port buffers from the
154 caller of the ptob seek procedure to the implementation. This
155 gives more control in general to the ptob seek: in particular the
156 change of 1999-10-20 can be made to work without breaking seek on
157 string ports. There's a comment in NEWS about upgrading port
160 * ports.c (scm_seek): don't reset the port buffers here.
162 * fports.c (fport_seek): reset the buffers, except for the
165 * strports.c (st_end_input): (bug fix): decrement pt->read_pos by
166 offset. check that it's not less than read_buf.
167 (st_seek): reset the buffers first, unless it's the 0 SEEK_CUR
168 case and currently reading.
170 1999-10-20 Gary Houston <ghouston@freewire.co.uk>
172 * ports.c (scm_seek): Add a special case for SEEK_CUR, offset 0,
173 so that unread chars are not needlessly discarded. (thanks to
176 1999-10-18 Gary Houston <ghouston@freewire.co.uk>
178 * fports.c (scm_fdes_to_port): always set rw_random if the fdes is
179 random access. rw_active needs to be maintained even for single
180 directional ports, otherwise scm_seek and probably other things are
181 broken. (thanks to Roland Orre).
183 * strports.c (scm_mkstrport): set rw_random to 1 unconditionally.
185 * ports.c (scm_add_to_port_table): initialise rw_random to 0.
187 * ports.h (scm_port): change the comments on rw_random and rw_active.
189 1999-10-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
191 * ioext.c: Added #include "feature.h".
193 These changes turns `delay' into a memoizing macro. This is
194 because it may be expanded before evaluation if it occurs at the
195 beginning of a body. (Thanks to Lauri Alanko.)
197 * eval.c, eval.h (scm_sym_delay): New global symbol.
199 * tags.h (SCM_IM_DELAY): New immediate symbol.
201 * print.c (scm_isymnames): Printed representation.
203 * eval.c (unmemocopy, SCM_CEVAL): Handle SCM_IM_DELAY.
204 (scm_m_delay): Turned into a memoizing macro.
206 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version.
208 1999-10-11 Jim Blandy <jimb@savonarola.red-bean.com>
210 * gh_data.c (gh_ints2scm, gh_doubles2scm): Make sure elements are
211 protected from GC while building the vector. (Thanks to Bernard
212 Urban and Greg Harvey.)
214 1999-10-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
216 * throw.c (handler_message): Display backtrace if backtraces
219 1999-10-05 Jim Blandy <jimb@savonarola.red-bean.com>
221 * Makefile.in, scmconfig.h.in: Deleted from CVS repository. Run
222 the autogen.sh script to create generated files like these.
224 * numbers.c (scm_string_to_number): Signal an error if radix is
225 less than two. (Thanks to Jorgen Schaefer.)
227 * print.c (scm_write, scm_display, scm_newline, scm_write_char):
228 Don't assume that the current output port is valid. Somebody
229 might close it. (Thanks to Bernard Urban.)
231 1999-10-02 Jim Blandy <jimb@zwingli.cygnus.com>
233 * scmconfig.h.in: Regenerated.
235 * Makefile.am (EXTRA_libguile_la_SOURCES): fix typo.
237 Mon Sep 27 17:15:14 1999 Greg J. Badros <gjb@cs.washington.edu>
239 * __scm.h: Fix a bunch of macros that were missing do-while(0)
242 * debug.c, eval.c: Fix buggy uses of SCM_ALLOW_INTS (missing
243 semicolon) exposed by the above change.
245 1999-09-27 Greg J. Badros <gjb@cs.washington.edu>
247 * stacks.c: Avoid compiler warning re: unitialized var.
249 * scmconfig.h.in: Added DEBUG_FREELIST
251 * pairs.h: Fix macro that was not do-while(0) sandwiched.
253 * gc.h, gc.c: Added scm_gc_set_debug_check_freelist_x,
256 1999-09-23 Gary Houston <ghouston@freewire.co.uk>
258 * ioext.c (scm_init_ioext): enable "i/o-extensions" feature here
259 instead of in scm_init_filesys.
261 * init.c (scm_boot_guile_1): don't call scm_init_posix or
262 scm_init_filesys unless HAVE_POSIX is defined.
263 don't call scm_init_netdb or scm_init_socket unless
264 HAVE_NETWORKING is defined.
266 * Makefile.am (EXTRA_libguile_la_SOURCES): filesys.c, posix.c,
267 net_db.c, socket.c: moved here from libguile_la_SOURCES.
269 1999-09-25 Jim Blandy <jimb@savonarola.red-bean.com>
271 * root.c (scm_make_root): Initialize all the fields of the new
272 root. GC could happen any time, you know. (Thanks to Greg
275 * numbers.c (scm_number_to_string): Signal an error if radix is
276 less than two. (Thanks to Jorgen Schaefer.)
278 * Makefile.am (EXTRA_libguile_la_SOURCES): Add memmove.c here,
279 so automake will actually generate rules for it.
280 * Makefile.in: Regenerated.
282 1999-09-21 Jim Blandy <jimb@savonarola.red-bean.com>
284 * backtrace.c: #include "_scm.h" before testing whether
285 HAVE_UNISTD_H is #defined.
287 1999-09-20 Jim Blandy <jimb@savonarola.red-bean.com>
289 * read.c (scm_read): Don't assume that scm_cur_inp is always open.
290 * ports.c (scm_read_char): Same.
291 * ioext.c (scm_read_line): Same.
292 (Thanks to Bernard Urban.)
294 1999-09-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
296 * vectors.c (scm_vector_move_right_x): Bugfix: Remove side effect
298 numbers.c: Removed #ifndef SCM_RECKLESS at places where type
299 checking may invoke a generic. (Thanks to Michael Livshin.)
301 * __scm.h (SCM_WTA_DISPATCH_0, SCM_GASSERT0): New macros.
303 * numbers.c (scm_max, scm_min, scm_sum, scm_difference,
304 scm_product, scm_divide): Bugfix: Don't pass SCM_UNDEFINED to the
305 generic function if the asubr is called with only one arg.
307 1999-09-20 Gary Houston <ghouston@freewire.co.uk>
309 * scmsigs.c (scm_sigaction): add SA_RESTART to flags only if
310 HAVE_RESTARTABLE_SYSCALLS.
311 (scm_init_scmsigs): use siginterrupt if it's available. not
312 everyone who has restartable syscalls has SA_RESTART it seems.
314 (scm_sigaction): use scm_num2long/scm_long2num when converting
315 SIG_DFL/SIG_IGN, in case it doesn't fit in an INUM. use
316 scm_integer_p to test the type.
318 1999-09-18 Gary Houston <ghouston@freewire.co.uk>
320 * _scm.h, scmsigs.c: replace HAVE_RESTARTS with
321 HAVE_RESTARTABLE_SYSCALLS.
323 * strports.c (scm_strport_to_string): create the string from
324 pt->read_buf instead of an expression that evaluates to the
327 * gdbint.c (gdb_print): don't just use SCM_CHARS to get a C string
328 from the port: the port's buffer may not be NUL terminated.
330 1999-09-16 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
332 * Makefile.am (.c.x): Added missing semicolon after `false'.
334 1999-09-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
336 * print.c (scm_iprin1): Turn `write' and `display' into
337 primitive generics and use their associated generic functions in
338 scm_iprin1 for GOOPS objects.
340 * backtrace.c: #include <unistd.h> if present.
342 1999-09-14 Jim Blandy <jimb@savonarola.red-bean.com>
344 * Makefile.am (.c.x): Don't create a subshell just to delete the
345 .x file and return false.
346 * Makefile.in: Regenerated.
348 1999-09-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
350 * feature.c (scm_create_hook): New function. Replaces
351 scm_make_named_hook which is now deprecated.
352 (scm_make_hook_with_name): New primitive.
353 (print_hook): Hooks now print in a fancy way.
355 1999-09-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
357 * __scm.h, backtrace.c, backtrace.h, debug.c, debug.h, dynl-dld.c,
358 dynwind.c, dynwind.h, eval.h, evalext.c, evalext.h, feature.c,
359 feature.h, hashtab.c, hashtab.h, objects.c, objects.h, print.c,
360 procs.c, procs.h, smob.c, smob.h, srcprop.c, strorder.c, struct.c,
361 struct.h: Updated copyright notices.
363 * srcprop.c (scm_source_property): Bugfix: Use SCM_NECONSP instead
364 of SCM_NCONSP. (Thanks to Greg Badros.)
366 * gsubr.c (scm_make_gsubr): Use scm_make_subr_opt for creation of
369 * eval.c, debug.h (SCM_BACKTRACE_WIDTH): New debug option: width.
371 * backtrace.c: Keep backtraces within specified width by
372 adaptively adjusting fancy printing parameters and cut output if
374 (scm_display_application): Check args.
376 1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
378 Change the name of the objects returned by OPENDIR from
379 "directory" to "directory stream". A predicate named "directory?"
381 * filesys.c (scm_directory_stream_p): Renamed from scm_directory_p.
382 At the Scheme level, "directory?" -> "directory-stream?".
383 (scm_dir_print): Use the phrase "directory stream" in printed form.
384 * filesys.h (scm_directory_stream_p): Prototype renamed
387 * Makefile.am (CLEANFILES): Remove versiondat.h; that should only
388 be removed by `make distclean', since it's generated by configure.
389 * Makefile.in: Regenerated.
390 (Thanks to Robert Bihlmeyer.)
392 * strop.c (scm_substring_move_x): Signal an error if start1
393 doesn't come before end1. (Thanks to Karoly Lorentey).
395 * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
396 calling SCM_NIMP. (Thanks to Karoly Lorentey).
398 * version.c (scm_libguile_config_stamp): Deleted. See
399 corresponding change to ../ice-9/boot-9.scm.
400 * versiondat.h.in: Remove definition for GUILE_STAMP.
401 * version.h: Delete prototype.
402 * Makefile.in: Regenerated.
404 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
406 * filesys.c (scm_directory_p): new procedure "directory?" Returns
407 a boolean indicating whether its argument is a directory
408 port as returned by opendir (thanks to Dirk Herrmann for the
411 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
413 * backtrace.c (display_frame_expr): Don't print a newline.
414 (display_frame): Print the newline here instead.
415 (display_backtrace_body): Don't print "Backtrace:".
416 (scm_backtrace): Print "Backtrace:" here instead.
418 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
420 * procs.c (scm_setter): Signal WTA if handed an entity or operator
423 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
424 primitives. (Thanks to Greg Badros);
425 (scm_hook_to_list): New primitive; Hooks are now smobs.
427 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
429 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
430 of #f for the 10th vector element to avoid an exception
431 seen by Bernard Urban.
432 (scm_mktime): unneeded ASSERT removed.
434 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
436 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
439 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
441 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
443 * numbers.c: Converted comparison operations to dispatch on
444 generic if args don't match.
446 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
448 1999-09-06 James Blandy <jimb@mule.m17n.org>
450 * guile-snarf.c: Deleted. Snarfing should respect CPP
451 conditionals, so it needs to actually run CPP. Bleah.
453 1999-09-05 James Blandy <jimb@mule.m17n.org>
455 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
456 * guile-snarf.in: Be sure to exit with an error if CPP does.
457 * Makefile.am (.c.x): Delete the .x file and exit with an error
458 status if guile-snarf exits with an error status.
459 * Makefile.in: Regenerated.
461 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
462 scm_makekey, which doesn't exist any more. Guess nobody's using
465 * guile-snarf.c: New implementation of guile-snarf, meant to be
466 more robust than the shell script. I think it's complete, but I
467 haven't tested it at all, and I haven't changed the build process
468 to actually use it. We should compare its output against that of
469 the existing shell script, for all source files.
471 * guile-snarf.c (parse_args): Abort if we haven't handled some
474 1999-09-03 James Blandy <jimb@mule.m17n.org>
476 * load.c (scm_search_path): If the filename has any extension at
477 all, ignore the entire list of extensions. Also, don't check whether
478 the file is accessible. If the file exists, accessible or not, we
479 should return it. Inaccessible files should cause an error later.
480 (Thanks to Keisuke Nishida for the suggestions.)
482 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
484 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
485 atexit not available. (sunos4.1.4 needs it.)
487 1999-09-01 James Blandy <jimb@mule.m17n.org>
489 I take it all back --- bcopy does handle overlapping source and
490 destination areas correctly. At least on every system I could
491 find. But it is better to use AC_REPLACE_FUNCS than to introduce
492 new CPP conditionals.
493 * memmove.c: New file, implementing memmove in terms of bcopy.
494 * scmconfig.h.in: Regenerated.
496 Allocators should use the `void *' type for generic pointers.
497 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
498 argument and return types.
499 * gc.h: Corresponding changes to prototypes.
502 1999-08-31 James Blandy <jimb@mule.m17n.org>
504 * numbers.c (scm_init_numbers): Claim to support the `complex'
505 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
507 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
508 find (ice-9 boot-9) when Guile was compiled in a separate
509 directory from the source. (Thanks to Rodney Brown.)
510 * Makefile.in: Regenerated.
512 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
513 table lengths by the size of a single element when growing the
514 table. (Thanks to Bill Schottstaedt.)
516 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
518 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
519 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
520 since that cuts down the time for type dispatch by 50%.
522 1999-08-30 James Blandy <jimb@mule.m17n.org>
524 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
525 not a correct substitute for memmove, because it doesn't handle
526 overlapping source and destination areas on many platforms.
527 Overlaps are the primary reason to use memmove in the first place.
528 * ports.c (scm_ungetc): Same.
529 * strop.c (scm_substring_move_x): Same.
531 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
533 * gc.c (scm_init_storage): Skip registration of cleanup on systems
534 which lack atexit. (Is it important that cleanup is made
535 properly? Maybe we should replace all `exit' with `scm_exit' and
538 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
539 scm_struct_free_standard, scm_struct_free_entity): Declared to
540 return scm_sizet instead of size_t.
542 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
543 there on sunos4.1.4.)
545 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
547 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
548 Account for the case when second argument is unbound.
550 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
551 (Thanks to Karoly Lorentey.)
553 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
554 isn't present. (Thanks to Suzuki Toshiya.)
556 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
559 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
562 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
563 Bernard Urban and Ian Grant.)
565 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
566 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
567 change in the representation of entities and operators.)
569 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
571 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
572 don't allocate zero bytes (thanks to Bill Schottstaedt).
574 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
576 * procs.c (scm_setter): Converted to use generic dispatch.
578 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
581 * load.c (scm_search_path): Don't try extensions which already are
582 present at the end of the filename.
583 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
585 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
587 Cleanup and simplification of generic method dispatch.
588 Also, the quadruple representation of entity and operator
589 procedures has been replaced with single.
591 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
593 * print.c (scm_isymnames): Removed #@hash-dispatch.
595 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
596 from eval.c; Support 0 arity methods.
597 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
598 (scm_apply_generic_env): Removed.
599 Replaced slots proc0-3 with procedure.
601 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
602 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
603 SCM_OPERATOR_PROCEDURE.
604 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
605 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
607 * struct.c, struct.h: Replace 4 procedure slots with one.
608 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
610 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
613 * eval.c (scm_sym_args): Removed.
614 (SCM_CEVAL): Simplified entity application.
615 Moved dispatch code to objects.c.
617 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
619 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
621 * sort.c (closureless): Use scm_eval_body.
623 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
624 with a symbol as last form was first called normally and then via
625 `map' or some other mechanism using primitive apply, an ILOC was
628 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
630 This change extends the representation of primitive procedures
631 with more data fields, e.g. a place for documentation and true
632 procedure properties.
634 * procs.c, procs.h (scm_subr_entry): New type: Stores data
635 associated with subrs.
636 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
637 SCM_SUBR_DOC): New macros.
638 (scm_subr_table): New variable.
639 (scm_mark_subr_table): New function.
641 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
643 * gc.c (scm_gc_mark): Don't mark subr names here.
644 (scm_igc): Call scm_mark_subr_table.
647 This change implements a scheme for letting a generic work as a
648 shadow for a primitive procedure. If the primitive procedure
649 can't dispatch on its arguments, control is left over to the
650 generic. Normal wrong type arg errors will be generated until the
651 user has hung the first method on the primitive.
653 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
655 * procs.c, procs.h (scm_subr_p): New function (used internally).
657 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
659 * objects.c, objects.h (scm_primitive_generic): New class.
661 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
663 * print.c (scm_iprin1): Print primitive-generics.
665 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
666 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
668 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
669 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
670 primitives). NOTE: This means that it is now *required* to use
671 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
672 obscured representation that will be removed in the future anyway,
673 so backward compatibility is no problem here).
675 * numbers.c: Converted most numeric primitives (all but bit
676 comparison operations and bit operations) to dispatch on generic
680 Better support for applying generic functions.
682 * eval.c, eval.h (scm_eval_body): New function.
684 * objects.c (scm_call_generic_0, scm_call_generic_1,
685 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
689 Optimization of the generic function dispatch mechanism.
691 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
692 called scm_memoize_method instead of doing a second lookup.
694 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
699 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
700 scm_sysintern so that the binding connected with the subr name
701 isn't cleared when we give set = 0.
704 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
706 More transparent handling of ports with print states.
708 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
709 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
710 instead of a pair of a port and a print state. We'll need to cons
711 once extra in scm_printer_apply but the type system will be
712 cleaner, it will mix better with GOOPS, and, it will be even more
713 transparent to the user.
715 * print.c (scm_get_print_state): New procedure: Given an output
716 port, return the print state associated to it in the current print
717 chain, if one exists;
718 (scm_port_with_print_state): New procedure: Associate a
719 print-state with a port.
720 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
721 (scm_printer_apply): Wrap port and pstate as a smob;
722 (print_state_printer): Removed.
724 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
726 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
729 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
730 testing (otherwise the port-print-state trick won't be transparent
731 to the user; one example where this caused problems was in the
732 (ice-9 format) module).
734 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
736 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
737 SCM_UNSPECIFIED instead of the set value.
739 1999-08-20 James Blandy <jimb@mule.m17n.org>
741 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
743 * ports.h (enum scm_port_rw_active): New enum, containing
744 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
745 zero). The debugger knows about enums, but doesn't know about
747 (typedef scm_port): Declare rw_active member to be an enum
749 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
751 * ports.c (scm_add_to_port_table): Same.
752 * strports.c (st_flush, st_end_input): Same.
754 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
755 scm_must_realloc, and scm_done_malloc as appropriate.
757 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
759 * sort.c (quicksort): Added condition to protect the algorithm
760 from crashing the interpreter if the less predicate is buggy.
762 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
764 * fports.c (fport_write): fix line-buffering mode again.
765 (scm_open_file): recognise 'l' for line-buffering.
766 (scm_setvbuf): recognise _IOLBF for line-buffering.
768 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
770 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
773 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
776 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
778 * fports.c (fport_write): use memcpy instead of strncpy, in case
779 the data contains NUL.
781 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
783 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
785 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
786 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
787 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
788 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
789 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
790 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
791 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
792 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
793 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
794 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
795 scm_sym_ as prefix for symbols.
797 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
799 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
800 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
801 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
802 scm_sym_atcall_cc): Made global.
804 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
806 * eval.c (scm_sym_args): Made global.
808 * objects.c (scm_set_object_procedure_x): Disallow setting of
809 procedures for pure generic functions.
811 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
813 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
814 Scheme name from lseek to seek, but lseek was added recently so
815 it shouldn't be a big problem.
816 * ports.c, gdbint.c, ioext.c: changed callers.
818 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
820 * fports.c (fport_input_waiting): if select is used, return 1
821 instead of whatever FD_ISSET expands to. maybe it will be useful
822 to interpret the value from the input_waiting ptob procedure as a
823 lower bound on the number of bytes available.
825 * Mikael asked for a few names to be changed...
827 * ports.c (scm_make_port_type): take the write procedure as the
828 second argument instead of the flush procedure.
829 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
830 fflush -> flush, read_flush -> end_input, fclose -> close,
831 fill_buffer -> fill_input, ftruncate -> truncate,
832 input_waiting_p -> input_waiting.
834 * ports.c (end_input_void_port): was read_flush_void_port.
835 (scm_set_port_end_input): was scm_set_port_flush_input.
836 (scm_set_port_flush): was scm_set_port_write.
837 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
838 (scm_end_input): was scm_read_flush.
839 (scm_fill_input): was scm_fill_buffer.
840 (scm_flush): was scm_fflush.
841 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
842 (fport_end_input): was local_read_flush.
843 (fport_flush): was local_fflush.
844 (fport_close): was local_fclose.
845 (fport_truncate): was local_ftruncate.
846 (fport_seek): was local_seek.
847 (fport_free): was local_free.
848 (fport_fill_input): was fport_fill_buffer.
849 * strports.c (st_end_input): was st_read_flush.
850 (st_truncate): was st_ftruncate.
851 * vports.c: (sf_flush): was sfflush.
852 (sf_close): was sfclose.
853 (sf_fill_input): was sf_fill_buffer.
855 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
858 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
860 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
861 forms now contain the expressions to be dispatched upon instead of
862 depending on a surrounding lambda or let; Generic function
863 dispatch has been optimized; `apply' on a generic function now
864 works a little bit strangely. It uses a trick so that the type
865 dispatch code in SCM_CEVAL can be reused.
867 * objects.h, objects.c (scm_apply_generic_env): Added (used by
869 (scm_operator_p): Added.
870 (scm_sym_atdispatch): Added.
871 (scm_set_object_procedure_x): Modified to handle the new style
873 (scm_object_procedures): New debugging procedure.
875 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
877 * eval.c, eval.h (scm_sym_args): Added.
879 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
881 * feature.c, feature.h (scm_c_run_hook): Added.
883 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
884 cdrxnoap and loopnoap instead of begin and loop.
886 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
888 * ports.c (scm_putc, scm_puts),
889 * unif.c (scm_uniform_array_write): use scm_lfwrite.
890 * ports.c (scm_putc): change type of first argument from int to char.
892 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
894 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
895 SCM_IM_HASH_DISPATCH.
897 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
898 (scm_si_redfined, scm_si_hashsets): Moved.
900 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
901 flag which combines type and status info so that the class
902 redefinition protocol has zero cost during normal execution.
904 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
906 * ports.h (scm_ptob_descriptor): include a write procedure again.
907 it's more efficient for unbuffered fports (e.g., sockets.)
909 * ports.c (scm_puts): use ptob->write.
910 * vports.c (scm_make_sfptob): set write proc in ptob.
911 * strports.c (scm_make_stptob): set write proc in ptob.
912 * ports.c (write_void_port): new procedure.
913 * vports.c (sf_write): new procedure.
914 * ports.c (scm_lfwrite): use ptob->write.
915 * strports.c (st_write): new procedure.
916 * fports.c (fport_write): new procedure.
917 (scm_make_fptob): set write in ptob to fport_write.
918 * ports.h: prototype for scm_set_port_write.
919 * ports.c (scm_make_port_type): initialise ptob write procedure.
920 (scm_set_port_write): new proc.
922 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
924 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
925 until we've verified that it is actually a port. (Thanks to
928 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
930 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
931 code, particularly an unnecessary test (len != size, where len ==
932 size). (Was this leftovers from debugging code, or have I missed
935 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
936 size. (Thanks to James Dean Palmer.)
938 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
939 (Thanks to Lorentey Karoly.)
941 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
943 * eval.c (scm_m_expand_body): Use scm_cons_source.
945 * struct.c (scm_print_struct): Use vtable name.
947 * print.c (scm_init_print): Set name of print state type.
949 * stacks.c (scm_init_stacks): Set name of stack type.
951 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
953 * eval.c (SCM_CEVAL): Removed old implementation of internal
956 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
958 * debug.c, debug.h (scm_reverse_lookup): Added.
959 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
960 internal procedure definitions; Don't use scm_i_inner_name.
962 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
965 * eval.h: Added prototypes for multi language support functions.
967 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
968 improper lists in the low-level representation, since that will
969 cause a begin to be prepended at macro expansion.
971 * eval.c (scm_cons_source): Version of cons which copies source
972 properties from an existing cell.
973 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
975 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
976 procedure source before calling scm_unmemocopy instead of faking
979 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
981 Ported `internal defines' fix from SCM. Original ChangeLog entry:
983 1998-07-09 Radey Shouman <radey@colorage.com>
985 * eval.c (ceval_1): Modifications to allow rewriting of interal
986 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
987 body of which it is the CAR is macro expanded by m_expand_body,
988 which rewrites internal DEFINE.
990 (m_expand_body): Added.
992 (m_macroexp1): Added argument to control error checking:
993 m_expand_body may speculatively expand forms in the wrong
994 environments. Made argument number checks conditional on
997 (m_body): Added, error checks bodies and inserts the ISYM tokens.
999 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
1002 (m_cond): (m_case): (m_quote): Modified to avoid destructively
1003 changing their argument forms. Since m_expand_body
1004 speculatively macro expands forms the process must be
1007 (m_ident_eqp): Fixed to use proper environment.
1009 (renamed_ident): Added DEFER_INTS_EGC.
1011 Added prototypes for static functions.
1017 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
1018 is false, do not produce an error for unbound variables, return a
1019 pointer to cell_undef instead.
1021 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
1025 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
1026 destructively changing their argument forms. Since m_expand_body
1027 speculatively macro expands forms the process must be reversible.
1029 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
1030 SCM_IM_LET introduced by named lets.
1032 (scm_m_letstar): Use scm_m_body instead of bodycheck.
1034 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
1035 scm_letrec. scm_letrec1 does not check for a null binding and
1036 takes an additional argument to specify the ISYM of the body. Use
1037 scm_m_body instead of bodycheck.
1039 (scm_m_let): Use scm_m_body instead of bodycheck.
1041 (scm_m_expand_body, scm_macroexp): New.
1043 (unmemocopy): Account for ISYMs introduced by scm_m_body.
1045 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
1046 check=1. Throw error for internal defined that have not been
1047 rewritten by scm_m_expand_body.
1049 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
1050 Removed prototype for SCM_APPLY.
1052 * tags.h: Added extern declaration of scm_isymnames.
1054 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1056 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
1058 * lang.c: New file: Beginning of multi-language support.
1060 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
1062 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
1063 (scm_dynamic_wind): Added argument checking for the after guard so
1064 that we don't add garbage on the dynwind chain.
1065 (scm_swap_bindings): Added.
1067 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
1068 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
1069 (scm_isymnames): New isyms for multi-language support.
1071 * eval.c (scm_nil, scm_t): New symbols.
1072 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
1073 forms for multi-language support.
1075 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1077 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
1079 Renamed functions in the random function library interface
1080 from scm_i_XXX --> scm_c_XXX.
1082 1999-07-25 Gary Houston <ghouston@easynet.co.uk>

1089 scm_set_ptob_XXX --> scm_set_port_XXX.
1091 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1093 * ports.c, ports.h (scm_make_port_type): New interface for
1094 creation of port types (replaces scm_newptob). Just as for the
1095 smobs, we need to separate the internal representation of smob
1096 types from the interface, so that we easily can add new fields and
1097 rearrange things without caring about backward compatibility.
1098 This change was forced by the need in GOOPS to create classes
1099 representing port types.
1100 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
1101 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
1102 scm_set_ptob_seek, scm_set_ptob_truncate,
1103 scm_set_ptob_input_waiting_p): New setters.
1104 (scm_newptob): Rewritten to use scm_make_port_type. For backward
1106 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
1107 (scm_prinport): Removed.

1109 (scm_print_port_mode): Added.
1110 (void_port_ptob, print_void_port, close_void_port, noop0):
1111 Removed. Removed #include "genio.h" Added #include "objects.h",
1114 * fports.c (prinfport): Moved code from ports.c.
1115 (local_free): Added.
1116 (scm_fptob): Removed. Instead use new interface.
1117 (scm_make_fptob): Added. (Need to create basic ports in a
1118 specific order in ports.c.)
1120 * strports.c (scm_stptob, prinstpt, noop0): Removed
1121 (scm_make_stptob): Added.
1123 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.

1135 Removed #include "genio.h"
1137 * objects.c (scm_make_port_classes): New function ptr.
1139 1999-07-24 Gary Houston <ghouston@easynet.co.uk>

1143 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
1144 allow the 1st argument to be a fdes or filename as well as a
1145 port (as in the filesys.c version).
1147 * filesys.c (scm_truncate_file): removed.
1149 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1151 * readline.c, readline.h: Removed.

1163 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1165 * init.c: Make sure that scm_post_boot_init_modules is called only
1166 once. (Important when using a dumped image.; Thanks to Bernard
1169 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
1171 * guardians.c (scm_guardian_zombify): Separate scanning for
1172 zombies from marking the pairs of the free list.
1174 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
1175 use the macros. (Thanks to Michael Livshin.)
1177 * eval.c (scm_m_lambda): Let bodycheck check the body of the
1178 lambda. Let your sins be purified by the blood of the lambda.
1179 (Thanks to Eric Hanchrow.)
1181 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
1182 (Thanks to Valdis Kletnieks.)

1186 * filesys.c: #include <io.h>, if we have it.
1187 * scmconfig.h.in: Regenerated.
1189 * stime.c (ftime): Delete declaration for this function --- let
1190 the system supply it.
1192 Cleanups from John Bley.
1194 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
1196 * gsubr.c: Don't include "gsubr.h" twice.
1198 Cleanups for compilation on Irix 6, from David Kaelbling.
1200 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
1201 regex_t pointer. This is what the callers have, mostly.
1202 (scm_regexp_exec): Don't forget to pass the `rx' argument to
1203 scm_regexp_error_msg.
1205 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
1206 int. That way, if we get a warning on this line, it's more likely
1207 that we're really missing bits we care about.
1209 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
1212 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
1213 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
1214 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
1215 cast at all is more appropriate in every case. At the moment, we
1216 assume everywhere that SCM is an integral type anyway.
1218 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
1220 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment

1227 fports.c (fport_fill_buffer): implement the interface change.
1229 * ports.c (scm_fill_buffer): interface change: no longer increments
1230 read_pos past the character that's returned. it seems clearer to
1231 leave it to the caller to decide what to do (thanks Jim).
1233 * vports.c (sf_fill_buffer): put the read char into the buffer
1234 as well as returning it.
1236 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

1254 it's greater and reset read_buf_size.
1255 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
1256 to be maintained for output ports too (it holds the written
1257 part of the string, while write_buf may have unwritten buffer
1259 (st_truncate): rewritten.
1260 (top of file): added a few notes.
1262 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
1264 Patch from Greg Badros:
1265 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
1266 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
1267 (function pointer) argument to scm_make_gsubr and scm_make_subr
1268 calls. This avoids warnings in C++ programs using guile-snarf.
1270 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
1272 * strports.c (st_grow_port): set pt->read_pos. set
1273 pt->read_buf_size one less than pt->write_buf_size if there's
1274 an unwritten char at the end of the string. similarly for
1276 (st_resize_port): renamed from st_grow_port.
1277 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
1278 seek from read_end instead of write_end for SEEK_END.
1279 (st_ftruncate): calculate current length using readbuf, not write
1281 (scm_strport_to_string): use read_buf_size for length.
1282 (stfill_buffer): don't re-initialise the readbuf.

1297 * smob.c: added scm_make_smob_type_mfpe (), scm_set_smob_mfpe ();
1298 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
1299 and "bigneg" smob types.
1301 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
1302 SCM_RETURN_NEWSMOB macro. Added protos for new functions in
1305 * *.c: Use scm_make_smob_type_mfpe, instead of scm_newsmob, and
1306 use SCM_NEWSMOB or SCM_RETURN_NEWSMOB in constructors instead of
1307 SCM_NEWCELL and setting the CAR/CDR by hand.

1331 buffer before calling the ptob routine.
1333 * strports.c (scm_strprint_obj): bug fix: get pt from the port,

1391 trinary conditional in order for the flag computation to be
1394 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1396 * struct.c, struct.h:
1398 In order to support different kinds of deallocation, a destructor
1399 slot has been added to struct vtables. This allows for structs
1400 containing pointers to other memory blocks.
1402 (scm_struct_i_free): New hidden struct slot. Holds destructor for

1474 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1475 around the condition of an `if', `while', etc., even if the
1476 condition is a macro invocation that expands to something
1477 surrounded by parens. It's more readable.
1479 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1480 proper lists, and of the appropriate lengths.
1481 (check_map_args): New function. (Thanks to Greg Harvey for the
1484 1999-06-19 Michael Livshin <mike@olan.com>

1523 vectors without allocating new storage during GC, using
1524 scm_weak_vectors as the head of the chain.
1525 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1526 instead of stepping through an array.

1539 * fports.c (local_seek): Signal an error if the seek fails.
1540 * ports.c (scm_lseek): Don't check return value of port's seek

1555 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1557 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1558 it shows up as terrible performance, as we GC constantly.

1575 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1576 and there's a newline to be written, flush the port.
1578 Gary Houston's open-buffer port patches:
1580 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1582 * ports.c: (scm_lseek): clear buffers even if just reading current

1611 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1613 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1614 equivalent to fflush for the read buffer.
1615 * ports.c (scm_newptob): set read_flush.
1616 ports.c (void_port_ptob): set read_flush.
1617 fports.c (local_read_flush): new proc. add to ptob.
1618 strport.c (st_read_flush): likewise.
1619 vport.c (sf_read_flush): likewise.
1620 fports.h (struct scm_fport): remove random member. there's nothing

1622 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1623 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1624 ptob proc if the read buffer is filled.
1626 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1628 * ports.h (scm_port): add a rw_random member and replace
1629 reading and writing members with rw_active member.
1630 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1632 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1634 * ports.h (struct scm_port_table): add writing and reading members
1635 to replace write_needs_seek: it isn't good enough for non-fports.
1636 ports.c, ioext.c, fports.c: corresponding changes.
1637 (struct scm_port_table): give it a typedef and rename to scm_port.
1638 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1639 corresponding changes.

1649 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1650 signals (it was only being done for handlers installed from Scheme).
1651 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1652 waiting for input caused an EINTR error from read.
1654 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1656 * ports.h (struct scm_port_table): make all the char members

1659 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1661 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1662 with threads enabled. rename this procedure to
1663 fport_wait_for_input and take a port instead of a fdes.
1664 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1666 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1667 get readline support working again: use fdopen to get FILE objects.
1669 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1671 * gc.c (scm_init_storage): install an atexit proc to flush the
1673 (cleanup): the new proc. it sets a global variable which can be
1674 checked by the ptob flush procs to avoid trying to throw
1675 exceptions during exit. not very pleasant but it seems more reliable.
1676 * fports.c (local_fflush): check terminating variable and if set
1677 don't throw exception.
1678 * CHECKME: that the atexit proc is installed if unexec used.
1680 * throw.c (scm_handle_by_message): don't flush all ports here.
1681 it still causes bus errors.
1683 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1684 and move to ioext.c.
1686 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1688 * ports.c (scm_char_ready_p): check the port buffer and call the
1689 ptob entry if needed.
1691 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1692 ptob initialisers. use it in char-ready
1694 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1696 * vports.c (sfflush): modified to write a char (since softports
1697 currently use shortbuf.)
1699 * fports.c (scm_standard_stream_to_port): moved to init.c and
1702 * init.c (scm_init_standard_ports): make stdout and stderr
1703 unbuffered if connected to a terminal. with stdio they
1704 were line-buffered by default.
1706 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1709 * ports.h (scm_ptobfuns): change fflush return to void.
1710 change flush proc definitions.
1712 * strports.c (scm_call_with_output_string): get size from
1713 buffer instead of port stream.
1714 (st_flush): new proc.
1716 * ports.h (struct scm_port_table): added write_end member,
1717 as an optimisation. set it where write_buf_size is set.
1719 * ports.h (struct scm_port_table): change stream from void *
1720 back to SCM. SCM presumably must be large enough to hold a
1721 pointer (and probably vice versa but who knows.)
1722 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1724 (scm_puts): rewritten
1725 * fports.c (local_ffwrite, local_fputs): removed.
1726 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)

1733 * fports.c (local_fputc): deleted.
1735 * ports.c (scm_add_to_port_table): initialise write_needs_seek.
1737 * ports.h (scm_ptobfuns): add seek function pointer.
1738 * fports.c: set it to local_seek, new procedure.
1741 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1742 use ptob for seek. take ptob instead of fport arg.
1744 * ports.h (struct scm_port_table): new member write_needs_seek,
1745 replaces reading member in fport struct.
1747 * vports.c (sfgetc): store the getted char into the buffer.
1748 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1749 the Scheme interface is still a procedure that gets a char.
1750 (scm_make_soft_port): set up the port buffer (shortbuf).
1752 * fports.c (local_fgetc, local_fgets): deleted.
1753 * strports.c (stgetc): likewise.

1759 put just the string into the stream, not cons (pos stream).
1760 (stfill_buffer): new proc.
1762 * ports.h: fport buffer moved into port table: to be
1763 used for all port types.

2086 SCM_ASSERT (<cond>, obj, "Undigestable object: %S", <subr>);
2088 1999-03-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2090 * list.c (scm_reverse): Report an error if given a circular list
2091 instead of filling memory.
2092 * list.c (scm_reverse_x): Check args.
2094 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2096 Most of this batch of changes is about how to deal with extended
2097 types when an object system is loaded into Guile. A nice object
2098 system is capable of representing Guile's types as class objects.
2100 For example, we want a regular expression to be of class <regex>.
2101 But regular expressions are smobs which aren't under direct
2102 control of the object system, so there has to be some mechanism
2103 which informs the object system that a new class should be created
2104 which can represent the smob type. I call this a "wrapper class".
2106 * objects.c: #include "smob.h";
2107 (scm_class_keyword): Removed. (Class is automatically created by
2109 (scm_smob_class): Array of smob classes indexed by smobnum.
2110 (scm_make_extended_class): "Plugin" function pointer for creation
2111 of wrapper classes for smob and struct types.
2112 (scm_class_of): Handle compiled closures. (Currently regarded as
2114 Use scm_smob_class to handle smob types;
2115 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
2116 through scm_smob_class;
2119 * smob.c (scm_newsmob): Also create a wrapper class if
2120 scm_smob_class has been initialized.
2122 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
2123 type code and smobnum.
2125 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
2126 (scm_struct_table): Weak key table with auxilliary information for
2127 struct types. Currently used for names and wrapper classes.
2128 (scm_struct_ihashq): Hash function for structs.
2129 (scm_struct_create_handle): Get/create entry in scm_struct_table.
2130 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
2131 for accessing names of vtables. The record implementation in
2132 boot-9.scm currently uses the setter to record the name of record
2133 types. When the object system is initialized, it can use this
2134 information to create wrapper classes with suitable names.
2135 (scm_init_struct): Allocate scm_struct_table.
2136 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
2137 (struct tags are a finite resource and we might want to restrict
2138 the use of tags to vtables only. E.g., Goops only uses tags for
2140 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
2142 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
2145 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
2146 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
2147 Used for access of struct table entries.
2149 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
2150 (scm_hash_fold): New procedure. Used to process all entries in a
2151 hash table (in no particular order).
2153 Argh! For the umpteenth time I got compilation errors because of
2154 the "intuitive" name `kw'. This has to have an end:
2156 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
2157 "kw" --> "keywords" everywhere.
2158 (I doubt that this will cause big compatibility problems since the
2159 application interface is unaffected.)
2161 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
2163 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2165 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
2166 column inums to native form.
2168 Improvement of backtraces: Introduces a new stack narrowing
2169 specifier, #t, for the inner cut. (See further in the comments in
2170 stacks.c:narrow_stack ().)
2172 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
2173 (Used to flag certain system procedures which shouldn't turn up in
2176 * eval.c (scm_sym_system_module): New symbol. (Used to flag

2188 * debug.c (scm_procedure_name): Use name property in the default
2191 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
2193 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
2195 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
2196 procedure throughout.
2198 * print.c (scm_iprin1): Removed extraneous space when printing
2199 procedure-with-setters.
2201 Entity and operator setter slots were introduced as a complement
2202 to the <procedure-with-setter> type in order to support entities
2203 and operators with setters in a reasonable and efficient way.

2220 directly through the instance.
2222 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
2224 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
2225 scm_struct_i_flags instead of scm_vtable_index_layout!
2227 * list.c (scm_list_star): New procedure.

2310 SYMB now point to const.
2312 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2314 * print.c (scm_iprin1): Use scm_procedure_name instead of
2315 scm_procedure_property for compiled closures.
2317 * tags.h (scm_tc7_pws): New procedure type. Four representations
2318 for procedure-with-setters were considered before selecting this
2321 1. A closure where the CODE and ENV slots are used to represent
2322 the getter and a new SETTER slot is used for the setter. The
2323 original getter is stored as a `getter' procedure property. For
2324 closure getters, the CODE and ENV slots contains a copy of the
2325 getter's CODE and ENV slots. For subr getters, the CODE contains
2328 2. A compiled closure with a call to the getter in the cclo
2329 procedure. The getter and setter are stored in slots 1 and 2.
2331 3. An entity (i.e. a struct with an associated procedure) with a
2332 call to the getter in the entity procedure and the setter stored
2333 in slot 0. The original getter is stored in slot 1.
2335 4. A new primitive procedure type supported in the evaluator. The
2336 getter and setter are stored in a GETTER and SETTER slot. A call
2337 to this procedure type results in a retrieval of the getter and a
2338 jump back to the correct eval dispatcher.
2340 Representation 4 was selected because of efficiency and
2343 Rep 1 has the advantage that there is zero penalty for closure
2344 getters, but primitive getters will get considerable overhead
2345 because the procedure-with-getter will be a closure which calls
2348 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
2349 <procedure-with-setter>, but together with rep 2 it suffers from a
2350 three level dispatch for non-GOOPS getters:
2352 cclo/struct --> dispatch proc --> getter
2354 This is because the dispatch procedure must take an extra initial
2355 argument (cclo for rep 2, struct for rep 3).
2357 Rep 4 has the single disadvantage that it uses up one tc7 type
2358 code, but the plan for uniform vectors will very likely free tc7
2359 codes, so this is probably no big problem. Also note that the
2360 GETTER and SETTER slots can live directly on the heap, using the
2361 new four-word cells.
2363 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

2590 handle operators and entities.
2591 (scm_procedure_property): No need to call scm_procedure_p since
2592 scm_i_procedure_arity now does all necessary type checking.
2593 Added #include "objects.h".
2595 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2596 s_add_hook_x --> s_remove_hook_x.
2597 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
2598 Added #include "procprop.h"
2600 * feature.c, feature.h (scm_reset_hook_x): New procedure.
2601 (scm_make_hook): Optional argument defines number of arguments to
2603 (scm_make_named_hook): Take number of args as second arg.
2604 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2605 boot-9.scm for a while); First arg is the hook. The rest are
2606 arguments passed on to the hook procedures.
2608 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2610 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2611 scm_logbit_p): Do the computation in ulongs. This is not as nice
2612 as doing it in bignums, but at least it's good enough for
2613 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2615 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2616 subexpressions. (Thanks to Charbel Jacquin.)
2618 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2620 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2621 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2622 (scm_make_named_hook): New function.
2624 * feature.c: Added #include "eval.h".
2626 * modules.c (scm_make_module): Beautify the module.
2628 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2630 * modules.c, modules.h: New files: C interface to modules. (This
2631 is necessary in order to interface the object system to Guile
2632 properly. The guts of these modules will be replaced by the new
2633 module system in the future.)
2635 * init.c: Added #include "modules.h"
2636 (scm_boot_guile_1): Call scm_init_modules.
2637 (invoke_main_func): Call scm_post_boot_init_modules.
2639 * Makefile.am: Added modules.c, modules.x, modules.h.
2641 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2643 * procs.c: #include "objects.h"
2644 (scm_procedure_p): Return #t also on structs which are operators.
2646 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2647 <operator-metaclass> and <entity-class> to <standard-class>,
2648 <operator-class> and <entity> in order to conform with STKlos
2651 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2652 which isn't an operator.
2653 (SCM_APPLY): Ditto, but jump to badproc.
2655 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2657 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2658 Previously, structs implanted in code were interpreted as forms
2659 the operator of which was a gloc. We solve this by checking for
2660 the zero in the emulated vcell in the struct vtable. Since
2661 implanted structs always will look like forms with a gloc
2662 operator, execution will only be slowed down by maximally one
2663 extra test-and-branch per application.
2665 * evalext.c (scm_definedp): Removed check for isyms; Added a
2666 second optional argument: It is now possible to supply an
2667 evaluation environment in which to look for the symbol.
2669 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2671 * readline.c (scm_init_readline): Set
2672 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2674 * coop.c (coop_condition_variable_wait): Removed
2675 (coop_condition_variable_wait_mutex): Folded logic of
2676 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2677 prevent condvar signal lossage. Previously, another thread could
2678 start to run after unlocking the mutex but before putting the
2679 current thread on the wait queue. If that thread then would
2680 signal the first, the signal would be lost. (Thanks to Christian
2683 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2685 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2688 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2690 * objects.c (scm_i_make_class_object): Renamed from
2691 make_class_object; exported; error checking moved to
2692 scm_make_class_object and scm_make_subclass_object.
2693 (scm_make_class_object, scm_make_subclass_object): Use
2694 scm_i_make_class_object.
2695 (scm_make_subclass_object): Let the subclass have same metaclass
2698 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2700 * debug.c (scm_debug_options): Bugfix: Set the value of
2701 scm_stack_checking_enabled_p after setting debug options;
2702 #include "stackchk.h". (Thanks to Richard Polton.)
2704 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2706 * unif.c (scm_array_contents): removed unnecessary test for 0
2709 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2711 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2712 Replaced by macro `collect' in boot-9.scm.
2714 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2716 * eval.c (scm_copy_tree): Copy source properties if existent.
2718 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2719 don't, we may end up passing memoized source to a transformer.)
2721 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2723 * stack.c (get_applybody): Help function which lookups the first
2724 body form of the apply closure.
2725 (read_frames): Prevent the source of the first form of the apply
2726 closure from being recorded. This would only be confusing.
2728 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2729 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2731 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2733 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2735 (read_frames): Use SCM_MACROEXPP.
2737 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2739 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2740 don't contain interesting information since all arguments are
2741 present in the frame which applies the compiled closure anyway.);
2742 Skip the transformer application frames.
2744 * print.c (scm_iprin1): Print gsubrs as primitives.
2746 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2748 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2750 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2751 that we can identify these in a backtrace. (This change doesn't
2752 introduce any significant speed penalty.)
2754 * eval.c: Added note about `serial-map' using scm_map.
2756 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2757 readline options. They should reside in their own options array.
2759 * readline.c, readline.h (scm_readline_options,
2760 scm_readline_opts): Moved readline options here.
2762 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2764 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2765 SCM_ROCHARS instead of SCM_CHARS.
2767 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2768 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2770 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2772 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2773 This is quite important since the latter clears the
2774 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2775 every single character read...
2777 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2779 * print.c (scm_iprin1): Removed suspect looking (and indeed
2780 malevolent) semicolon after test for user supplied closure print
2781 procedure. (Thanks to Telford Tendys.)
2783 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2784 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2785 starting to search the list. Removed call to sloppy_mem_check.
2787 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2788 procedures: Same as scm_delq_x et al, but delete maximally one
2791 * options.c (scm_options, scm_init_options): GC-protect option
2792 values of type SCM. (Thanks to Telford Tendys.)
2794 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2796 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2797 make sure that there always is a "real" scm_lookupcar.
2799 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2801 * read.c, read.h (scm_read_opts): New read options
2802 "history-length" and "history-file".
2803 (scm_read_options): Stifle history to history length.
2805 * readline.c (scm_read_history, scm_write_history): New procedures.
2807 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2809 * eval.h (scm_macro_eval_x): Removed declaration.
2811 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2812 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2813 Renamed and made global.
2815 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2816 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2818 * evalext.c, evalext.h: New files. Contain non-R5RS things
2819 having to do with evaluation.
2821 * evalext.c (scm_serial_map): New procedure: Version of `map'
2822 which guarantees that the procedure is applied to the lists in
2824 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2825 returns a list of the results of the body forms instead of the
2826 result of the last body form.
2827 (scm_definedp, scm_m_undefine): Moved from eval.c
2829 * evalext.h (scm_m_sequence_to_list): Added declaration.
2831 * macros.c, macros.h: New files.
2832 (scm_procedure_to_syntax, scm_procedure_to_macro,
2833 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2834 scm_macro_name, scm_macro_transformer): Moved from eval.c
2835 (scm_make_synt): Moved from eval.c
2837 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2839 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2842 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2844 * debug.c, print.c: Added #include "macros.h".
2846 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2848 This change adds the ability to use `unread-char' multiple times
2849 without interspersed reads and adds the new procedure
2850 `unread-string'. The change is optimized for the common case of
2851 unreading a single character. This is also the reason behind the
2852 choice to store characters in the port itself: in most cases no
2853 extra malloc is required.
2855 The amount of code in some macros in ports.h has been increased to
2856 the extent that they would fit better as C functions, but, since
2857 this code belongs to the port representation, such functions
2858 should be placed in ports.c which would cause calls back and forth
2859 between ports.c and genio.c. That is not good for performance.
2860 Also, keeping them as macros allows the compiler to do some
2861 optimizations which are needed to make the current interface
2862 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2864 One benchmark (Guile startup time) indicates an increase of
2865 loading speed of 1%. Another (reading (using `read') boot-9.scm
2866 10 times) shows no change in performance.
2868 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2869 made to find a beautiful solution.)
2871 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2872 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2873 character. (SCM_CLRDY clears all.)
2874 (SCM_N_READY_CHARS): New macro: Returns number of unread
2875 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2876 (struct scm_port_table): New fields: `entry' contains port table
2877 index, `cp' points to last unread char, `cbuf' is the buffer for
2878 unread chars, `cbufend' points after end of the character buffer.
2880 * ports.h, ports.c (scm_unread_string): New procedure.
2881 (scm_grow_port_cbuf): New function.
2883 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2885 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2886 to read unread characters. Use SCM_TRY_CLRDY instead of
2889 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2891 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2893 * genio.c, genio.h (scm_ungets): New function.
2895 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2898 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2900 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2901 declarations. (Thanks to Russ McManus.)
2903 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2905 * numbers.c (num2long): As a software archeologist, I'm proud of
2906 this finding! :) Preliminary dating suggests an almost 4 year old
2907 remnant from the SCM ancestor. The sample has been removed from
2908 the finding site and is now safely stored in the repository.
2910 * numbers.h: Removed prototype for num2long.
2912 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2914 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2915 array as second arg.
2916 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2917 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2918 * gh.h: Updated and added prototypes.
2920 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2922 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2924 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2926 * guile-snarf.in: Never generate an empty file. (Thanks to
2929 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2930 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2931 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2932 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2933 gh_new_procedure5_0): Specify argument types, to appease C++
2934 compilers. (Thanks to Brad Bowman.)
2936 Bug reports from Russ McManus:
2937 * guile-snarf.in: If the CPP environment variable is set, use that
2938 as the C preprocessor, instead of the preprocessor autoconf
2940 * snarf.h (SCM_PROC): Cast the function pointer passed to
2941 scm_make_gsubr, to satisfy C++.
2943 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2944 Use the handler passed, instead of ignoring it and using
2945 gh_standard_handler. (Thanks to Etienne Bernard.)
2947 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2949 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2952 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>
2954 * __scm.h, alist.c, async.c, async.h, backtrace.h, chars.c,

2969 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2972 * script.c (scm_compile_shell_switches): Define
2973 use-emacs-interface in the root module, so the repl code can see
2974 it. See today's change to top-repl in ice-9/boot-9.scm.
2976 * filesys.c (set_element, get_element): Make sure that `element'
2977 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2978 Boekemeier and Jorgen "forcer" Schaefer.)
2980 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2982 * chars.c (scm_charnames): In ASCII character name table, make
2983 newlines print as #\newline by default, not #\nl.
2985 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2986 alphabetical order. Oh thrills. But it helps me know how far
2987 along in the compilation I am.
2988 * Makefile.in: Regenerated.
2990 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2992 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2993 #bytes(...) to #y(...), and syntax for short vectors from
2994 #short(...) to #h(...). This may seem nutty, but, like the other
2995 uniform vectors, byte vectors and short vectors want to have the
2996 same print and read syntax (and, more basic, want to have read
2997 syntax!). Changing the read syntax to use multiple characters
2998 after the hash sign breaks with the conventions used in R5RS and
2999 the conventions used for the other uniform vectors. It also
3000 introduces complexity in the current reader, both on the C and
3001 Scheme levels. (The Right solution is probably to change the
3002 syntax and prototypes for uniform vectors entirely.)
3004 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
3006 Don't use local_fgets on sockets; ftell doesn't work on sockets.
3007 (Thanks to Jorgen "forcer" Schaefer.)
3008 * ports.h (SCM_NOFTELL): New flag.
3009 * fports.c (local_fgets): If it's set, use the generic fgets.
3010 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
3012 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3014 * script.c (scm_compile_shell_switches): Add handling of -q switch
3015 (inhibit loading of user init file).
3016 (scm_shell_usage): Add usage text for -q switch.
3017 (scm_compile_shell_switches): Always load user init file first if
3018 it is loaded at all.
3020 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
3022 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
3023 and is now broken under NetBSD. I can't fathom what it's trying
3024 to do, so I've replaced it with something that I do understand,
3025 which seems to work, and which isn't broken on NetBSD. "Progress?
3026 You Decide." (Thanks to Perry Metzger.)
3028 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
3029 signed/unsigned comparison.
3031 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
3033 Warning fixes from Greg Harvey:
3034 * unif.c (scm_array_set_x): initializer for pos
3035 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
3036 * struct.c (scm_struct_ref, scm_struct_set_x): Added
3037 initializers for field_type, since EGCS so desparately wants to
3039 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
3040 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
3041 when GUILE_DEBUG is defined.
3042 * dynwind.h (scm_wind_chain): Same.
3043 * ports.h (scm_pt_size, scm_pt_member): Same.
3044 * print.h (scm_current_pstate): Same.
3045 * procs.h (scm_make_cclo): Same.
3047 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
3049 Handle short and long long uniform arrays properly. (Thanks to
3051 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
3052 raeql_1): Add cases for scm_tc7_svect (short vectors) and
3053 scm_tc7_llvect (long long vectors).
3055 Change the way libguile and boot-9.scm are timestamped, to try to
3056 get rid of these spurious mismatch warnings. Now both
3057 libguile/versiondat.h and ice-9/version.scm are generated directly
3058 by the configuration process, rather than having version.scm
3059 generated directly, and libguile/versiondat.h generated by the
3060 Makefile, which is generated by configure. It seems that
3061 sometimes the Makefile would change, but versiondat.h depends on
3062 Makefile.in, not Makefile, so it wouldn't get rebuilt.
3063 * Makefile.am (versiondat.h): Target removed; this is generated
3064 directly by the configure script now.
3065 (BUILT_SOURCES): Remove versiondat.h.
3066 * versiondat.h.in: New file, transformed by the configure script
3068 * Makefile.in: Regenerated.
3070 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
3071 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
3072 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
3073 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
3074 if we want to use them in a header file some day, we can. (Thanks
3075 to Michael Livshin.)
3077 * stime.c (scm_get_internal_real_time): Do the arithmetic using
3078 SCM numbers, so we won't have rollover problems; the range of a
3079 signed long in milliseconds is about 25 days. (Thanks to Karl
3082 Don't redefine sleep and usleep; fix this problem now.
3083 * coop.c (sleep, usleep): Remove declarations; we don't use or
3084 redefine these any more.
3085 (scm_thread_usleep, scm_thread_sleep): New functions which do the
3086 job of usleep and sleep in a thread-friendly way. We can use
3087 these in the rest of Guile. Define versions for systems both with
3088 and without iselect.
3089 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
3090 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
3091 we're just using it, not redefining it, we can use a K&R style
3093 (sleep): Declare this, too, if the system hasn't.
3094 (scm_sleep, scm_usleep): Use scm_thread_sleep and
3095 scm_uthread_sleep if they're available; otherwise, just call the
3097 * scmconfig.h.in: Regenerated.
3099 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
3101 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
3103 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
3105 * threads.c: Doc fix.
3107 The argument type of usleep varies from system to system,
3108 as does the return type. We really shouldn't be redefining usleep
3109 at all, but I don't have time to clean that up before the 1.3.
3110 release. It's on the schedule for afterwards. (Thanks to Julian
3112 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
3114 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
3115 * scmconfig.h: Regenerated.
3117 * simpos.c (scm_software_type): Procedure deleted. This isn't the
3118 right way to handle system variation. Autoconf's approach is the
3120 * simpos.h (scm_software_type): Declaration deleted.
3122 * script.c (scm_find_executable): Don't test if unix is #defined
3123 here; first, NetBSD doesn't #define it, and second, it's the wrong
3124 way to go about these things. (Thanks to Perry Metzger.)
3125 (dld_find_executable): Delete this MSDOS support code. This isn't
3126 the way we want to support this; it needs to be rethunk at a
3129 * genio.c (scm_do_read_line): Don't just politely check that the
3130 line was either non-empty or EOF. Abort if it's empty and not
3133 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
3135 * scmconfig.h.in: Regenerated.
3137 * libguile.h: Don't omit the dynamic linking functions. (Thanks
3140 * genio.c (scm_do_read_line): Count lines correctly when the file
3141 doesn't end in a newline.
3143 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
3145 * genio.c (scm_do_read_line): Maintain the line count correctly.
3146 (Thanks to Harvey J. Stein and Greg Harvey.)
3148 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
3151 * numbers.c (big2str): Protect t from garbage collection until
3152 we're done. (Thanks to Gary Houston.)
3154 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
3156 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
3158 * Makefile.in: Regenerated.
3160 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
3161 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
3164 Do magic to mix reads and writes on stdio FILE-based ports.
3165 (Thanks to Christian Lynbech.)
3166 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
3168 (pre_read, pre_write): New functions.
3169 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
3170 local_fputs): Call them.
3171 (local_fflush): Mark the port as ready for reading and writing.
3172 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
3173 flags on new port objects. This might not be accurate --- who
3174 knows what state the FILE * is in when we get it --- but it won't
3175 do extraneous calls to fflush or fseek, so it's no worse than the
3176 behavior before this change.
3177 * ports.h: Add comment.
3179 Centralize the creation of port objects based on stdio FILE * in
3180 fports.c; don't just throw them together anywhere.
3181 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
3182 what the rest of Guile wants. Don't set the revealed count;
3183 that's only appropriate for stdin, stdout, stderr.
3184 (scm_standard_stream_to_port): This function does set the revealed
3186 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
3187 not scm_stdio_to_port.
3188 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
3189 * fports.c (scm_open_file): Same.
3190 * posix.c (scm_pipe): Same.
3191 * socket.c (scm_sock_fd_to_port): Same.
3192 * ioext.c (scm_fdopen): Same.
3193 (scm_freopen): Moved from here to...
3194 * fports.c (scm_freopen): ... here. This is really something that
3195 munges the internals of an fport, so it should go here.
3196 * fports.h (scm_stdio_to_port): Adjust prototype.
3197 (scm_standard_stream_to_port, scm_freopen): New protoypes.
3198 * ioext.h (scm_freopen): Prototype removed.
3200 * filesys.c (set_element, get_element): This can work on both pipe
3201 and file ports, so use SCM_FPORTP to typecheck, instead of testing
3204 * scmconfig.h.in: Regenerated.
3206 Change the definition of the functions in scm_ptobfuns so that
3207 they get passed the port object, not the port's stream.
3208 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
3209 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
3210 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
3211 Pass the port itself to the scm_ptobs function.
3212 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
3213 scm_generic_fgets): Same.
3214 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
3215 getc_void_port, fgets_void_port, close_void_port): Just change the
3216 argument names; these functions don't really do anything.
3217 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
3218 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
3219 port as an argument, and use SCM_STREAM to get the stdio FILE *.
3220 Also, use prototyped definitions, and get rid of the extra
3222 (scm_fptob, scm_pipob): We don't need casts here any more.
3223 * strports.c (prinstpt): Use prototype declarations.
3224 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
3225 and use SCM_STREAM to get the string info. Also, use prototyped
3226 definitions, and get rid of the extra declarations.
3227 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
3230 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
3231 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
3233 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
3234 scm_fgets, for consistency.
3235 (scm_fptop, scm_pipob): References updated.
3237 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
3239 Include the source location in error messages for scripts.
3240 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
3241 stack is still there when we catch the error.
3242 * throw.c (handler_message): If we are handling an error with a
3243 message, then put together the proper arguments and call
3244 scm_display_error, instead of scm_display_error_message. That
3245 displays source location, if it can find it.
3247 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
3249 * gc.c (scm_unprotect_object): Change this so that calls to
3250 scm_protect_object and scm_unprotect_object nest properly.
3251 (scm_protect_object): Doc fixes.
3253 * strings.c (scm_string_set_x): Require the argument to be a
3254 writable string, not a substring or a symbol.
3255 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
3256 (Thanks to John Redford and Charbel Jacquin.)
3258 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
3260 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
3262 * eval.c (safe_setjmp): Remove this misunderstanding.
3263 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
3266 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
3268 * libguile.h: Mark these as C declarations, for compilation by C++
3271 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
3272 __cplusplus clause. I seriously doubt this ever worked the way
3273 the author seems to have intended.
3275 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
3277 Utterly needless cleanups to hopelessly messy code.
3278 * ports.c: Doc fixes.
3279 (scm_fflush): Moved to ...
3280 * genio.c (scm_fflush): ... here, amongst all the other port
3281 method invocation functions.
3282 * genio.h, ports.h: The prototype moves too.
3284 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
3286 * backtrace.c (display_error_body): The current frame does not
3287 always have a parent frame; consider a function called directly
3288 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
3291 * alloca.c (alloca): Undo yesterday's changes, and simply call
3292 malloc directly for storage, and abort if we don't get what we
3293 want. The situation is much simpler --- just call malloc. Emacs
3294 has bizarre/evil requirements (signal handlers might malloc unless
3295 you set this global flag, so you have to set the flag around all
3296 calls to malloc) which we are certainly not going to conform to,
3297 so we can do the simple and obvious thing.
3299 * coop.c (coop_condition_variable_wait): Make this function
3300 static. It's only useful internally --- you should never just
3301 wait on a condition variable.
3302 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
3304 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3306 * unif.c (scm_array_set_x): Accept any kind of number as an
3307 element for a uniform vector of doubles. This is more consistent
3308 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
3310 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
3311 works; I can't conveniently test it myself. (Thanks to Dvid
3312 Tillman for the bug report.)
3314 * init.c: Doc fixes.
3316 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
3317 from here, not from scm_compile_shell_switches (which is a pretty
3318 dumb place to do it).
3319 (scm_load_startup_files): New function.
3320 (scm_ice_9_already_loaded): Variable moved to here from script.c.
3321 * script.c (scm_compile_shell_switches): Don't load the startup
3323 (scm_ice_9_already_loaded): Variable moved.
3324 * init.c (scm_load_startup_files): Prototype for new function.
3325 * gh_init.c (gh_enter): Doc fix.
3327 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3329 Some anti-warning changes from Greg Harvey.
3330 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
3331 warnings when it doesn't understand our NORETURN declarations in
3333 * posix.c (scm_mknod): Similar.
3335 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3337 * posix.c (scm_getpwuid): If we can't find an entry, return our
3338 own message, instead of using scm_syserror --- the getpwMUMBLE
3339 functions don't set `errno' to anything interesting.
3341 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3343 Get rid of warnings from the cooperative threading system.
3344 * threads.h (scm_single_thread_p, scm_yield,
3345 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
3346 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
3347 scm_wait_condition_variable, scm_signal_condition_variable): Add
3348 prototypes for these Scheme-visible functions.
3349 * coop-defs.h (coop_next_runnable_thread,
3350 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
3351 Prototypes for these here, even though they're from iselect.c.
3352 (coop_condition_variable_wait, coop_join): Add prototypes.
3353 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
3354 scm_threads_free_condvar): Make these smob functions static.
3355 * coop-threads.h (coop_init): Give this a real prototype.
3356 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
3357 (coop_next_runnable_thread): No need to provide prototype; it's in
3360 * scmconfig.h.in: .detarenegeR
3362 * iselect.c, threads.c: Doc fixes.
3364 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3366 * Makefile.in: Regenerated with a patched automake, to get
3367 dependency generation right when using EGCS.
3369 * inet_aton.c (inet_aton): Add prototype, to remove compiler
3370 warning. (Thanks to Robert Pluim.)
3372 * inet_aton.c (inet_aton): Reassure the compiler that the
3373 arguments to the <ctype.h> macros are all unsigned characters, not
3376 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3378 Getting rid of more warnings...
3379 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
3380 today's change to ../configure.in.
3381 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
3382 * scmconfig.h.in: Regenertaded.de.,.__
3383 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
3384 (scm_localtime, scm_mktime): Use a const char * to manipulate the
3387 * readline.c: Doc fix.
3388 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
3389 * readline.h (scm_filename_completion_function): Add prototype.
3390 (scm_init_readline): Make this into a prototype.
3392 * readline.c (scm_filename_completion_function): Use SCM_PROC to
3393 declare this, instead of calling scm_make_subr manually.
3395 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
3397 * readline.h (scm_init_readline): Add prototype for this.
3398 (scm_init_readline): Make this a real prototype.
3400 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3402 Warning fixes from Maciej Stachowiak:
3403 * backtrace.h (scm_display_application, scm_backtrace): Add
3405 * debug.c (scm_m_start_stack): Make this function static.
3406 * fluids.h (scm_fluid_p): Add prototype.
3407 * procprop.c (scm_i_procedure_arity): Make this function static.
3408 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3409 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
3410 * root.h (scm_dynamic_root): Add external prototype.
3411 * scmsigs.h (scm_usleep): Add external prototype.
3412 * script.h (scm_init_script): Use prototype, not K&R decl.
3413 * stacks.h (scm_stack_id): Add external prototype.
3414 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3416 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3418 * gh.h: took out the definitions of vset and vref, since they are
3419 replaced by the proper vector routines that correspond to the R4RS
3422 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3424 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3425 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3426 third argument, a C expression that should result in a SCM value,
3427 which is used to initialize the variable. Reimplemented
3428 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3431 * version.h (scm_libguile_config_stamp): Add prototype.
3432 (From Maciej Stachowiak.)
3434 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3436 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3437 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3439 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3441 * print.c (scm_iprin1): Rather than having one i, and using it in
3442 several places, declare a fresh i local to each block where it is
3443 used, and give it a signedness appropriate to its use in each case.
3444 (scm_iprlist): Same.
3446 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3447 comparison warnings.
3449 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3450 signed/unsigned clashes.
3452 * posix.h (scm_tmpnam): Added prototype.
3454 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3455 scm_make_subclass_object): Add external prototypes.
3457 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3458 comparison is okay here.
3460 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3462 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3463 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3465 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3468 * load.c (swap_port): Make this function static.
3470 * load.c (scm_search_path): Make max_path_len and max_ext_len
3471 unsigned, since they're compared against string sizes.
3473 * load.c (init_build_info): Make i unsigned.
3475 * ioext.h (scm_read_line): Add prototype.
3477 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3478 scm_hash_fn_remove_x): Make hash bucket index local variable k
3479 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3480 accurately as possible.
3482 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3483 comparisons, and range checking to make sure those casts are
3486 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3487 signed/unsigned comparisons.
3489 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3490 avoid signed/unsigned comparisons.
3491 * smob.h (scm_numsmob): Change extern declaration to match.
3493 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3494 avoid signed/unsigned comparisons.
3495 * ports.h (scm_numptob): Change extern declaration to match.
3496 (scm_current_load_port, scm_set_port_line_x,
3497 scm_set_port_column_x): New prototypes.
3499 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3500 test code, and it causes warnings.
3502 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3503 gh_uniform_vector_ref): Added prototypes.
3505 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3506 debugging support unconditionally. That's backtrace.c, stack.c,
3507 debug.c, and srcprop.c.
3508 (EXTRA_libguile_la_SOURCES): Omit those from here.
3509 * Makefile.in: Regenerated.
3511 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3513 * options.c (scm_options): Bugfix: Allow empty list of options!
3515 * debug.c, debug.h (scm_single_step): Removed.
3516 (scm_with_traps): New procedure. This procedure could easily be
3517 written in Scheme but needs to be highly optimized.
3519 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3521 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3522 Check SCM_TRAPS_P before trapping.
3524 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3526 Changes to avoid signed/unsigned comparison warnings.
3527 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3528 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3529 so they can have appropriate types for each application. Make i
3530 signed. Use initializers in some spots. I'll probably pay for
3532 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3533 (scm_must_realloc): Make nm unsigned.
3534 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3535 (scm_init_storage): Use prototype-style definition, and make the
3537 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3538 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3540 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3541 avoid signed/unsigned comparison warnings, and because the return
3542 value of readlink may be -1. Don't bother casting the third
3543 argument to readlink.
3545 * filesys.c (scm_dirname, scm_basename): Move these to their own
3546 page, at the end of the file.
3547 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3549 * eval.h (scm_eval_options_interface): Add external prototype for this.
3550 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3552 * eval.c (scm_lookupcar1): Make this static.
3554 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3555 Make these prototype declarations, not K&R-style.
3557 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3558 unsigned comparison warning.
3560 * appinit.c: File removed. It had a single function in it, empty,
3561 whose reason for existence is explained in no documentation or
3562 comment. I think it's there as a default for some Tcl-style
3563 initialization, but Tcl abandoned that approach a while ago.
3564 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3565 (BUILT_SOURCES): Remove appinit.x.
3566 * Makefile.in: Regenerated.
3568 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3570 * Makefile.in: Regenerated using the last public version of
3571 automake, not the hacked Cygnus version.
3573 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3575 Remove Totoro kludge.
3576 * Makefile.in, scmconfig.h.in: Regenerated.
3577 * init.c, readline.c: Don't check if TOTORO is #defined.
3579 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3581 * Makefile.am: Adjust for new thread configuration system.
3582 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3583 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3585 (THREAD_LIBS): Definition deleted; automake will generate such
3586 things automatically.
3587 * Makefile.in: Regenerated.
3589 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3591 Simplify smob and port marking; set the mark bit in the generic
3592 marking code, and make marker routines only responsible for
3593 turning up outgoing pointers.
3594 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3595 before calling the marking function. Don't call the marking
3596 function if it's zero.
3597 * markers.c (scm_mark0): Just return #f. This function isn't
3598 necessary at all now, but it's harmless to call it. We'll leave
3599 it in so other folks' code doesn't croak at link time.
3600 (scm_markcdr): Don't call SCM_SETGC8MARK.
3601 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3602 * dynl.c (mark_dynl_obj): Same.
3603 * root.c (mark_root): Same.
3604 * srcprop.c (marksrcprops): Same.
3605 * unif.c (markra): Same.
3606 * variable.c (scm_markvar): Same.
3607 * ports.c (scm_markstream): Same.
3608 (void_port_ptob): Specify zero for our marking function.
3609 * debug.c (debugobjsmob): Same.
3610 * dynwind.c (guardsmob): Same.
3611 * filesys.c (dir_smob): Same.
3612 * fluids.c (fluid_smob): Same.
3613 * fports.c (scm_fptob, scm_pipob): Same.
3614 * mallocs.c (mallocsmob): Same.
3615 * regex-posix.c (regex_t_smob): Same.
3616 * smob.c (freecell, flob, bigob): Same.
3617 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3618 * throw.c (jbsmob, lazy_catch_funs): Same.
3620 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3622 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3623 scm_copy_tree on code in order not to let memoized code to leak
3624 out. Thus, scm_copy_tree needs to copy vectors as well since
3625 quasiquote can introduce evaluated code also inside vector
3628 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3630 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3632 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3633 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3636 * unif.c: Say that ivect and uvect are of type signed and unsigned
3637 long instead of int in commentary so that it correctly describes
3640 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3642 * stime.c: Removed declaration of strptime. (It should be
3643 declared by the system headers. If it turns out that some systems
3644 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3646 * stime.h: Renamed TIMEH --> STIMEH
3648 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3649 to increase portability, don't use structure assignment.
3650 (Thanks to Nicolas Neuss.)
3652 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3654 (finalize_fd_sets): Added empty statement after last case label.
3655 (Thanks to Nicolas Neuss.)
3657 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3660 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3662 * init.c, readline.c: OK, I won't have these readline.x bug
3663 reports anymore. We've had them since April. The current reason
3664 is a completely unintelligible failure of totoro.red-bean.com to
3665 do the test for rl_getc_function in libreadline correctly. This
3666 kludge overrides the test if we're on totoro so that the snapshot
3667 generation process can work.
3669 * readline.c: Define a strdup replacement if not existent on system.
3671 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3673 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3674 This change makes scm_make_vector R5RS compatible. We cannot keep
3675 the third argument since people want to be able to deduce the form
3676 of the C function call only by looking at R5RS. (At the same time
3677 we have removed some unnecessary complexity!)
3679 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3680 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3681 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3682 argument in call to scm_make_vector.
3684 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3686 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3687 This macro is useful in applications.
3689 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3691 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3692 (scm_parse_path, scm_search_path): New Scheme level procedures.
3694 * load.h (scm_internal_parse_path, scm_parse_path,
3695 scm_search_path): Declared.
3697 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3699 * filesys.c (dirname, basename): New procedures.
3701 * init.c (scm_boot_guile_1): Removed condition around
3704 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3705 new data type (guards) for representation of C level guards and
3706 data on the wind chain.
3707 (scm_internal_dynamic_wind): New function.
3709 * dynwind.h: Declare scm_internal_dynamic_wind.
3711 * root.h (scm_root_state): Added scm_cur_loadp.
3713 * root.c (mark_root): Added comment about cur_loadp.
3715 * load.c: #include "dynwind.h";
3716 (scm_primitive_load): Use scm_inner_dynamic_wind to update
3719 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3721 * ports.c (current-load-port): New procedure.
3723 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3725 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3726 not a tty, return #f.
3728 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3729 to Julian Satchell and Roland Kaufmann.)
3731 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3732 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3734 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3736 * debug.h, debug.c (scm_start_stack): New function. Implements
3737 the guts of old scm_m_start_stack.
3739 * debug.c (scm_m_start_stack): Use scm_start_stack.
3741 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3742 start_stack and restart_stack. (These have static scope.)
3744 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3746 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3747 readline functions to come in release 2.3. (Thanks to Chet
3749 (handle_errors): Use the above functions.
3751 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3753 * readline.c: Improvements for readline support: Handle errors
3754 better; Implement before-read-hook.
3756 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3758 * init.c (scm_boot_guile_1), readline.c: Test for
3759 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3760 assure that we have version >= 2.1.)
3762 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3764 * readline.c (scm_readline): Defer interrupts while we're calling
3767 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3768 away the string to add_history.
3769 (completion_function): Do completion for readline. (Thanks to
3771 (scm_filename_completion_function): New procedure: Filename
3773 (current_input_getc): New function. Use this one instead of
3774 standard getc from readline.
3776 * throw.c, throw.h (scm_handle_by_throw): New function: This
3777 handler throws errors to next handler on the dynwind chain.
3779 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3781 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3784 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3786 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3788 (scm_procedure_properties): Modified to return arity together with
3790 (scm_procedure_property): Added the read-only property `arity'.
3791 (scm_set_procedure_property_x): It is an error to set the `arity'
3794 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3795 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3797 * procprop.h (scm_sym_arity): New symbol.
3799 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3800 to set the dispatch procedure of an operator or entity object.
3802 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3803 Made procedure slots read-only.
3805 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3806 scm_tcs_cons_gloc case in zero args switch; Fixed args
3807 construction for operators in scm_tcs_cons_gloc case in two args
3810 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3812 * fluids.c: Removed use of assert.h (in order to avoid
3815 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3817 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3819 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3820 change makes the evaluator safer at the cost of evaluation speed.
3821 It handles the case when the user has added a non-immediate
3822 improper end of the application form, e.g., `(+ 0 . x)'.
3823 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3824 minimize the extra cost as much as possible. The new code is
3825 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3826 problem with structs planted directly in the code (e.g. by a
3827 macro). This no longer causes segmentation fault. (Thanks to
3830 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3831 arg `proc' in order to be able to throw errors; New argument
3834 * Removed extra #include "debug.h"
3836 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3838 * scmsigs.c: Declare usleep as returning void on some systems.
3839 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3842 * coop.c (usleep): Return void on some systems.
3844 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3846 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3848 * coop.c: Changed return type of usleep to int.
3850 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3851 isn't found in the OS.
3853 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3854 isn't enabled. (Thought that I had made this change ages ago...)
3856 * iselect.c: Declare bzero if not defined by OS.
3858 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3860 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3861 condition. (Thanks to John Tobey.)
3863 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3864 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3867 * __scm.h: Start the long-term project of moving to POSIX threads.
3868 Phase 1: Classification of all critical sections.
3869 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3870 for A sections. (See comments in __scm.h for details.)
3872 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3873 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3875 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3877 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3878 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3879 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3880 dependencies on $(srcdir)/Makefile.in
3881 $(top_builddir)/config.status in order to avoid circularity.
3883 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3884 from argc if argc was 0 initially.
3886 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3887 in generation of libpath.h.
3889 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3891 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3892 libguile from 2 to 3.
3894 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3896 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3898 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3900 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3901 scm_set_port_column_x, scm_port_filename,
3902 scm_set_port_filename_x): Removed optional arguments. Added
3903 proper argument checking.
3905 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3906 stack size in machine words.
3908 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3909 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3910 to Ole Myren Röhne.)
3912 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3914 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3915 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3917 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3920 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3921 procedure apply: Copy argument lists before pushing them unto the
3922 environment so that the environment won't get mutated due to
3923 manipulation of procedure arguments. This should perhaps be
3924 regarded as a temporary solution until someone finds a more
3925 efficient one. (Thanks to Maciej Stachowiak.)
3927 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3929 * script.c (scm_compile_shell_switches): Use "guile" as default
3930 zero arg if argc is NULL.
3932 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3934 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3935 is zero. (Thanks to Dirk Herrmann.)
3937 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3939 * ports.c (scm_add_to_port_table): First line is now line 0
3940 (was 1). (Interface changed according to suggestion by Per
3943 * backtrace.c (display_header): Add 1 to line and column numbers
3944 when presenting them to the user.
3946 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3947 from debug.c --> eval.c
3949 * eval.h, eval.c (scm_eval_options_interface): New options
3951 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3952 i.e. stacks for new threads.
3954 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3956 * eval.c (unsafe_setjmp): Removed with #if 0.
3958 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3961 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3962 to avoid compiler warnings.
3964 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3966 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3968 * throw.c (handler_message): Print message on current error port
3969 instead of default error port. (Thanks to Maciej Stachowiak.)
3971 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3973 * ports.c (scm_add_to_port_table): allocate in units of
3974 struct scm_port_table *, not struct scm_port_table.
3975 * posix.c (scm_close_pipe): remove the port from the port table
3977 Thanks to Rob Engle for both fixes.
3979 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3981 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3982 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3984 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3986 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3988 * backtrace.c (display_error_body, display_backtrace_body),
3989 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3990 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3991 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3992 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3995 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3996 don't receive the jmpbuf arg anylonger.
3997 (scm_catch): Don't accept a #f tag.
3998 (scm_throw): Check that key is a symbol.
3999 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
4001 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
4003 * async.c (async_pending): Removed declaration.
4005 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4007 * dynwind.c (scm_wind_chain): New debug function.
4009 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
4010 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
4011 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
4012 extra layer of functions around the body and handler of a thread.
4013 This extra layer makes sure that the handler is called in the
4014 dynamic context of the surround (= empty dynwind list), but under
4015 the *dynamic root* of the body. We can not use the dynamic root
4016 of the surround since that root belongs to another thread => stack
4017 is not handled correctly. It may seem ugly to use this extra
4018 layer, but the extra cost in terms of execution time is really
4019 negligible compared to the total amount of time required to create
4020 a thread, and it would reduce maintainability to duplicate the
4021 crucial and complicated steps performed by cwdr.
4023 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
4024 (SCM_ALLOW_INTS): Added thread switching code before interrupts
4025 get re-enabled. The important effect of this is that interrupts
4026 are blocked during thread switching so that thread data structures
4027 don't risk getting messed up by an unfortunate signal.
4028 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
4029 seems to do more aggressive optimization which actually move
4030 instructions around in these macros in a fatal way. Therefore:
4031 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
4032 just superstitious...)
4033 (SCM_TICK): Maybe do a context switch and take care of asyncs.
4034 This macro should be used instead of SCM_ASYNC_TICK since the
4035 latter doesn't do context switches any more.
4037 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
4038 instead of SCM_ASYNC_TICK.
4040 * coop.c, iselect.c: Since thread switches are now performed with
4041 interrupts masked, we can't use the old mechanism of delivering
4042 signals immediately when they arrive. Signals must instead be
4043 delivered when the asyncs run *after* the end of the critical
4044 section in scm_internal_select. But this also means after context
4045 switch so that the signal will be delivered to a different thread.
4046 To avoid this, I have changed the protocol of
4047 coop_wait_for_runnable_thread and friends so that they are allowed
4048 to return the original thread. So, if a signal arrives during
4049 scm_internal_select, we won't any longer be forced do a context
4050 switch, but can remain in the same thread and deliver the signal
4053 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
4054 scm_asyncs_pending and made it global.
4056 * iselect.c: Small fixes.
4058 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
4059 coop_condition_variable_init, coop_condition_variable_wait,
4060 coop_condition_variable_signal): Changed return type from `void'
4061 to `int'. This is to adhere closer to the pthreads interface.
4062 This, in turn, is part of an attempt to provide C versions of the
4063 mutex and condition variable primitives which can be part of a
4064 frontend to COOP or pthreads.
4066 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
4067 coop_condition_variable_destroy): New functions.
4069 * coop-threads.c (scm_wait_condition_variable): Use
4070 coop_condition_variable_wait_mutex.
4072 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
4073 Definitions moved to coop-defs.h.
4075 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
4076 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
4077 scm_cond_destroy): New C interface to mutecis and cond vars.
4079 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4081 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
4083 * iselect.c: Now several threads can wait on the same file
4084 descriptor. The behaviour is compatible with OS select: All
4085 threads waiting for the fd return with the same status.
4087 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4089 * coop-threads.c, threads.h (scm_spawn_thread): New function.
4090 Can spawn a thread from application C code.
4092 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4094 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
4095 gh_doubles2scm): New functions.
4097 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
4099 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
4100 commented-out version of gh_eval_str()
4102 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
4104 * socket.c (scm_bind): free soka after use.
4106 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
4108 * stime.c (tzvar): new variable.
4109 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
4110 avoid memory leaks when allocating.
4112 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
4114 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
4117 * gc.c, tags.h: Doc fixes.
4119 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4121 * eval.c (macro-eval!): Removed. This function was a design bug.
4122 It allowed memoized code to leak out to the scheme level. Most
4123 things that you could do with `macro-eval!' can be done with
4126 1997-12-20 Tim Pierce <twp@skepsis.com>
4128 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
4129 scm_fgets now depends on ftell(3) to know how many bytes were
4132 1997-12-15 Tim Pierce <twp@skepsis.com>
4134 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
4135 dealing with strings.
4137 1997-12-13 Tim Pierce <twp@skepsis.com>
4139 Make %read-line more suitable for implementing read-line efficiently.
4140 * ioext.c (scm_read_line): Strip the terminating newline from a
4141 string, and return a cons of the string and its terminator.
4143 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
4144 of the string that is read is stored in this memory location.
4145 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
4146 * genio.c, genio.h (scm_do_read_line): Update caller.
4147 * ports.h (scm_ptobfuns): Update typedef.
4148 * fports.c (scm_fptob, scm_pipob): Update struct.
4150 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4152 * filesys.c (set_element): Return file descriptor.
4153 (fill_select_type): Return the highest file descriptor.
4154 (scm_select): Tell select about the highest file descriptor. On
4155 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
4156 Therefore the extra overhead for calculating the maximum fd seems
4157 to be more than compensated. Is this correct? In any case,
4158 scm_internal_select will be much faster with this info.
4159 (scm_select, fill_select_type, set_element): Don't accept any kind
4160 of object in the file descriptor list or vector.
4162 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4164 * iselect.c (finalize_fd_sets): Bugfix.
4166 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4168 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
4169 when using scm_internal_select (since we might switch to another
4172 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
4174 * simpos.c (scm_system): always define: use sysmissing if not
4175 available. Check for HAVE_SYSTEM instead of _Windows (does
4176 Windows lack system or does it have an unusable one?).
4177 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
4178 Let the argument be optional: if not supplied, call system(NULL).
4180 * ports.c (scm_close_port): relax the type check from OPPORTP to
4181 PORTP; closing a closed port is allowed.
4183 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
4185 * fports.c (scm_fgets): Return if the last char in a chunk is
4186 newline. When fgets returns a string whose length is `size-1', it
4187 is ambiguous whether a whole line was retrieved, so we must check
4188 explicitly whether a line terminator is present.
4190 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4192 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
4193 before taking the CDR. (Thanks to Harald Meland.)
4195 * filesys.c (scm_stat): Slightly optimized.
4197 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
4199 * ports.c (scm_close_port): Make sure the port is open before
4202 * guile-snarf.in: Pass args through to gcc in a way that preserves
4203 whitespace boundaries. (Thanks to Greg Badros.)
4205 1997-12-02 Tim Pierce <twp@skepsis.com>
4207 * stacks.c (scm_frame_procedure): Reverse the logic in the return
4208 statement. (Thanks to Doug Evans for pointing this out.)
4210 1997-12-01 Tim Pierce <twp@skepsis.com>
4212 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
4214 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
4216 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
4217 errno macro expansion of this field name. (errno is a C
4218 preprocessor macro on some systems.)
4220 1997-11-29 Tim Pierce <twp@skepsis.com>
4222 * iselect.c: Doc fix.
4224 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
4226 * init.c (scm_start_stack): Removed initialization of
4227 scm_the_last_stack_var.
4229 * backtrace.h: Declare scm_the_last_stack_var.
4231 * backtrace.c: Define scm_the_last_stack_var.
4233 * root.c (mark_root): Don't mark the_last_stack_var.
4235 * root.h (scm_root_state): Removed the_last_stack_var.
4237 * throw.c: Added #include "fluids.h"
4238 (ss_handler): `the-last-stack' is now a fluid.
4240 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
4241 --> the_last_stack_fluid.
4243 * backtrace.c: Added #include "fluids.h"
4244 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
4245 (scm_backtrace): `the-last-stack' is now a fluid.
4247 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
4248 after scm_init_fluids.
4250 1997-11-28 Tim Pierce <twp@skepsis.com>
4252 * iselect.c: #ifdef USE_THREADS around thread-related includes.
4254 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
4255 DLSYM_ADDS_USCORE to decide whether to add an underscore.
4257 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4259 * iselect.c (coop_next_runnable_thread,
4260 coop_wait_for_runnable_thread): Disable interrupts so that no
4261 async is executed before a potential error_revive.
4262 (scm_internal_select): Disable interrupts during the parts of the
4263 code which manipulate the sleep queue and the file descriptors.
4265 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4267 * Makefile.am: Added iselect.c and iselect.h.
4269 * coop.c (coop_qinit): Initialize fields used by
4270 scm_internal_select.
4271 (coop_qget, coop_qget, coop_tmp_queue): Made global.
4272 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
4273 replacement in iselect.c.
4274 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
4275 coop_join): If GUILE_ISELECT enabled, use
4276 coop_wait_for_runnable_thread instead of
4277 coop_next_runnable_thread.
4278 (usleep, sleep): New replacements for system functions if
4279 GUILE_ISELECT is enabled.
4281 * coop-threads.h: Declare coop_wait_for_runnable_thread.
4283 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
4285 * filesys.c: Added #include "iselect.h". Moved FD-macros to
4286 iselect.h. Implement Scheme level `select' using
4287 scm_internal_select. (See NEWS.)
4289 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
4291 * init.c: Call scm_init_iselect.
4293 * iselect.h, iselect.c: New files. Implements
4294 scm_internal_select. (See NEWS.)
4296 1997-11-27 Tim Pierce <twp@skepsis.com>
4298 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
4299 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
4300 and scm_must_free, since ultimately the string returned will be copied
4301 by scm_makfrom0str anyway. Also, read any characters that may have
4302 been pushed onto the port with scm_ungetc.
4303 * ports.c (scm_generic_fgets): Same as for scm_fgets.
4304 * ioext.c (scm_read_line): Free string after Guilifying it.
4305 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
4307 1997-11-26 Anthony Green <green@hoser.cygnus.com>
4309 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
4311 * gh.h: Safely wrap prototypes for c++ usage.
4313 1997-11-25 Mark Galassi <rosalia@cygnus.com>
4315 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
4316 gh_repl (argc, argv).
4318 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
4320 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
4321 and to invoke scm_shell().
4322 (gh_launch_pad): took out the loading of boot-9.scm from here,
4323 since it is probably best to let the user control that. In fact,
4324 gh_repl() now invokes scm_shell() which does that.
4326 1997-11-23 Mark Galassi <rosalia@cygnus.com>
4328 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
4331 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
4333 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
4334 yesterday's underscore patch. (Thanks to Marius Vollmer for
4337 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
4339 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
4340 DLSYM_ADDS_USCORE is not defined.
4342 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
4344 * gh_data.c (gh_uniform_vector_length):
4345 (gh_uniform_vector_ref): started implementing the uniform types in
4348 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
4350 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
4351 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
4353 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
4355 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
4356 configure.in was changed).
4358 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
4360 * Makefile.am (modinclude_HEADERS): Include readline.h here.
4361 * Makefile.in: Regenerated.
4363 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
4365 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
4366 OPORT is an `open' port, not an output port.
4368 * filesys.c (scm_close, set_element, get_element, scm_chown,
4369 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
4370 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
4371 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
4372 scm_close_port, scm_port_line, scm_set_port_line_x,
4373 scm_port_column, scm_set_port_column_x, scm_port_filename,
4374 scm_set_port_filename_x, scm_port_mode,
4375 scm_close_all_ports_except, scm_set_current_output_port,
4376 scm_set_current_error_port): Likewise
4377 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
4378 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
4380 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
4381 * backtrace.c (display_backtrace_body): Likewise
4382 * fports (scm_setvbuf): Likewise
4383 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
4384 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
4385 scm_getpeername, scm_send, scm_sendto): Likewise
4386 * unif.c (scm_uniform_array_write): Likewise
4388 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
4390 Minor problems with substring-related tag changes.
4391 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
4392 exactly what we want to leave in to detect substrings.
4393 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
4394 * tags.h: Fix diagrams and comments describing the S tag bit;
4395 remove vestigial remarks about the D tag bit.
4396 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
4397 * strings.c: Formatting tweaks.
4399 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
4400 variable first; then SCHEME_LOAD_PATH, with a warning message.
4401 (scm_parse_path): New function.
4402 * script.c: Doc fixes.
4404 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
4406 Readline support, from Daniel Risacher.
4407 * readline.c, readline.h: New files.
4408 * init.c: #include "readline.h".
4409 (scm_boot_guile_1): Call scm_init_readline, if we have it.
4410 * Makefile.am (libguile_la_SOURCES): Include readline.c.
4411 * Makefile.in: Regenerated.
4412 * scmconfig.h.in: Regenerated, after change to ../configure.
4414 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4416 * gh.h: gh_vector_set -> gh_vector_set_x
4418 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4420 * gh_data.c (gh_vector_set_x): changed name to make it consistent
4421 with the ! -> _x mapping when going from Scheme to C.
4423 1997-10-19 Mark Galassi <rosalia@cygnus.com>
4425 * gh.h (gh_reverse):
4433 (gh_assoc): added these gh_ functions implemented as macros.

4436 (gh_string_equal_p): added these two missing predicates.
4438 * gh_list.c (gh_append):
4443 (gh_set_cdr_x): added these routines as I go through and try to
4444 complete the picture R4RS functions that should be mirrored in the
4447 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4449 * tags.h (scm_tc7_substring): Changed the comment and code to
4450 conform with the changes below. Folks! We have suddenly two new
4451 free tc7 codes!!! Jummy, jummy!
4453 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
4455 * Makefile.in: Rebuilt.
4456 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
4458 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
4459 * unif.c (scm_vector_set_length_x): Don't handle multibyte

4473 * eq.c (scm_equal_p): Use SCM_TYP7S, not SCM_TYP7SD.
4474 * tags.h (SCM_TYP7SD): Removed.
4475 (SCM_TYP7D): Removed.
4476 (scm_tc7_mb_string): Removed.
4477 (scm_tc7_mb_substring): Removed.

4480 Don't include "mbstrings.h".
4481 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
4482 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
4484 Don't include "mbstrings.h".
4485 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
4486 (SCM_SYMBOL_SLOTS): Define as 4.
4487 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.

4508 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
4509 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
4511 1997-10-12 Mark Galassi <rosalia@cygnus.com>
4513 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
4515 * gh_test_c.c (c_vector_test): some improvements on the vector
4518 * gh.h (gh_vector): this used to exist but do the wrong thing.
4519 Now it (almost) does the right thing, though it takes a list
4520 instead of the individual arguments. I need to see how it could
4522 (gh_list_to_vector): added this function as a macro. Corresponds
4523 to Scheme's (list->vector ...).
4524 (gh_vector_to_list): added this function as a macro. Corresponds
4525 to Scheme's (vector->list ...).
4527 * gh_data.c (gh_vector_ref): renamed from gh_vref to
4528 gh_vector_ref, so that it resembles the Scheme routines more.
4529 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
4530 resembles the Scheme routines more.
4531 (gh_make_vector): this used to be (stupidly) called gh_vector().
4532 This is the right name, since it does the same thing as the Scheme
4533 (make-vector ...) procedure.
4535 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4537 * ports.h: #include "libguile/print.h"

4540 Some indentation fixes.
4542 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
4543 longer a user field; New field: class_flags.

4549 * gh_data.c (gh_bool2scm): new function which replaces
4550 gh_int2scmb(), which is now tagged as obsolete.
4552 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4554 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4555 macros should by convention not test for NIMPness.)
4556 (SCM_COERCE_OPORT): Adjust indentation.
4558 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4559 SCM_NIMP test before SCM_PRINT_STATE_P.
4561 * struct.c, struct.h, gc.c: Renamed:
4562 scm_struct_i_layout --> scm_vtable_index_layout
4563 scm_struct_i_vcell --> scm_vtable_index_vcell
4564 scm_struct_i_vtable --> scm_vtable_index_vtable
4565 scm_struct_i_printer --> scm_vtable_index_printer
4566 scm_struct_i_vtable_offset --> scm_vtable_offset_user
4568 * struct.c (scm_print_struct): Use new printer slot; Default
4569 printing: Also output hex code of vtable so that type identity
4570 will be indicated as well.
4571 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4572 Removed struct_printer_var; Removed struct-vtable-offset;
4573 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4574 vtable-offset-user): New constants.
4576 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
4577 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
4578 If this slot contains a procedure, use that to print structures of
4579 the type represented by this vtable.
4581 * print.c (scm_iprin1): Don't print arguments of macro
4582 transformers. (They are always: exp env.); Bugfix: Unmemoize
4583 transformer source with correct environment.
4585 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4587 Streamlining of call-with-dynamic-root:
4589 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
4590 there is now only one catch.
4591 (cwdr_outer_body): Removed.
4592 (cwdr_handler): New function.
4593 (scm_internal_cwdr): New function to perform the function of cwdr
4594 but take args that are more useful to C code. Also, the handler
4595 is now invoked *outside* of the new dynamic root, like the docs
4596 say. We no longer have to catch absolutely all errors, the caller
4597 is responsible for using a handler that does not throw, if he
4599 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4600 * root.h (scm_internal_cwdr): New prototype.
4602 Even more but risky streamlining:
4604 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4605 allocation of the jumpbuf of a root continuation. The changes
4606 below are controlled by it. They are now deactivated.
4607 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4608 the JMPBUF of the scm_rootcont to NULL before returning.
4610 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4611 when they are non-NULL.
4612 (scm_gc_mark): Likewise, mark only when non-NULL.
4614 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4615 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4617 * gc.c (scm_done_malloc): New function.
4618 gc.h (scm_done_malloc): New prototype.
4620 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
4621 (struct scm_print_state) [revealed]: New field.
4622 (scm_print_state_vtable): Make visible to the outside world for
4623 type checking purposes.
4624 (scm_valid_oport_value_p): New prototype.
4626 * print.c (scm_valid_oport_value_p): New function to check whether
4627 a certain value is acceptable as a port argument.
4628 (scm_print_state_vtable): New variable.
4629 (scm_free_print_state): Set `revealed' field to false.
4630 (scm_iprin1): Call user supplied closure printer with
4631 scm_printer_apply. Print in the traditional way when there isn't
4632 one or when it returns #f.
4633 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4634 Accept a port/print-state pair in addition to just a port.
4635 (scm_prin1): Don't return the print_state to the pool when it has
4637 (scm_printer_apply): Set `revealed' field of print_state to true.
4638 (scm_init_print): Set scm_print_state_vtable.
4639 (print_state_fluid, print_state_fluid_num): Removed.
4641 * throw.h (scm_handle_by_proc_catching_all): New prototype
4642 throw.c (scm_handle_by_proc_catching_all): New function
4644 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4646 * Makefile.in: Regenerated with automake 1.2c.
4648 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4650 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4651 was looping endlessly.
4653 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4655 * strports.c (scm_eval_string): Don't close the port.
4657 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4658 former returns a nice normal integer. (Thanks to Daniel
4661 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4663 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4664 makefile variable as a build parameter called LIBS. The
4665 build-guile program will use this, for the time being.
4666 * Makefile.in: Regenerated.
4668 Thanks to Shiro Kawai:
4669 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4670 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4673 * Makefile.in: Regenerated with automake 1.2a.
4675 * script.c (scm_compile_shell_switches): If we hit the -c or --
4676 arguments, don't set the car of (command-line) to scm_usage_name,
4677 the prettified name of the guile executable; give it the full
4678 path, the way shells usually handle $0.
4680 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4682 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4683 Scheme-level name `array-map' and renamed `serial-array-map' to
4684 `serial-array-map!'.
4686 * backtrace.c: Introduced exception handlers which now enclose
4687 `display-error' and `display-backtrace' so that error reporting
4688 won't get into infinite loops if an error occurs during displaying
4689 of the error. This can very easily happen with user supplied
4690 print call-back routines.
4692 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4694 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4695 the names `serial-array-map' and `array-map' should be removed.)
4697 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4699 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4700 Added #include "objects.h"
4702 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4703 Add #include "feature.h".
4705 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4706 (modinclude_HEADERS): Added objects.h.
4708 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4709 This test is needed at many places in the code and should be
4710 abstracted. (Motivated by the need of this test in libguiletk.)
4712 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4713 (scm_eval_string), load.c (scm_primitive_load,
4714 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4715 Use SCM_EOF_OBJECT_P.
4717 * eval.c (scm_init_eval): Add feature `delay'.
4719 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4721 * scmhob.h: Removed.
4723 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4725 * list.h (SCM_LISTn): New macros. Make list creation in C code
4726 prettier. The idea comes from STk.
4728 * sequences.h, sequences.c, append.h, append.c: Removed. These
4729 files implemented non-R4RS operations which would encourage
4730 non-portable programming style and less easy-to-read code.
4732 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4735 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4736 sequences.h, #include append.h.
4738 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4741 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4743 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4745 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4747 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4749 * eval.c: Added #include "objects.h"
4751 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4754 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4755 adjacent smob numbers.
4757 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4759 * procprop.h: Added declaration of scm_i_inner_name.
4761 * gsubr.c: New global symbol scm_i_inner_name.
4763 * debug.c (scm_procedure_name): Try procedure property
4764 `inner-name' if `name' fails.
4766 * print.c (scm_iprin1): Use scm_macro_name.
4768 * eval.c (scm_m_define): Give names to macros as well; Only the
4769 first top-level definition gives a procedure/macro a name.
4770 Otherwise confusing names can turn up in backtraces.
4771 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4772 `name'; Give names to macros as well.
4774 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4775 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4778 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4780 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4782 (prinmacro): Removed. The code has been moved/merged into print.c
4783 in order to decrease code redundancy. We want macros to print in
4784 a way equivalent to procedures, and it would be silly to duplicate
4785 the required code. (We don't want to maintain two places.)
4786 (macrosmob): Print field is now a NULL pointer.
4788 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4789 scm_macro_transformer): New prototypes.
4790 (scm_tc16_macro): Declared.
4792 * print.c (scm_iprin1): Added code for printing of macros. Macros
4793 are now printed in a way equivalent to procedures.
4795 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4797 * procs.h (scm_closure_p): Added declaration.
4799 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4801 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4802 Shouldn't pass "heap" as the subr name.
4804 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4806 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4807 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4808 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4809 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4810 SCM_BOOL_T. Any non-false value is true.
4812 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4814 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4815 scm_gensym): Added prototypes.
4817 * symbols.c (scm_gensym): New function. This will speed up
4818 certain types of applications (such as macro systems) which
4819 generate lots of symbols.
4821 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4823 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4825 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4827 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4828 specifier, since (2) or (2 . 3) would cause SEGV.
4829 (scm_transpose_array): more argument checking fixes.
4831 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4833 * Makefile.in: Regenerated.
4835 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4837 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4839 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4841 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4843 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4845 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4846 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4849 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4850 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4851 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4852 scm_array_p, scm_array_rank, scm_array_dimensions,
4853 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4854 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4855 scm_array_prototype): Added case scm_tc7_wvect.
4857 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4859 * errno.h: prototype for scm_strerror.
4860 * error.c (scm_strerror): new procedure.
4862 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4864 * list.c (scm_list_append_x): Allow non-pair as last argument.
4865 This is consistent with the R4RS append and is probably the
4866 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4868 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4870 * stime.h: prototype for scm_times.
4871 * stime.c (scm_times): new procedure.
4872 * ioext.c (scm_fseek): if the first argument is a file descriptor
4874 (scm_ftell): if the first argument is a file descriptor call lseek
4876 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
4877 * filesys.c (scm_chmod): if the first argument is a file descriptor,
4879 (scm_chown): if the first argument is a port or file descriptor,
4881 (scm_truncate_file): new procedure.
4882 Add DEFER/ALLOW INTS to a few other procedures.
4883 (scm_fsync): new procedure.
4884 (scm_open_fdes): new procedure.
4885 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
4887 (scm_fcntl): the first argument can now be a file descriptor. The
4888 third argument is now optional.
4890 * posix.c (scm_execl, scm_execlp): make the filename argument
4891 compulsory, since omitting it causes SEGV.
4892 (scm_sync): return unspecified instead of #f.
4893 (scm_execle): new procedure.
4894 (environ_list_to_c): new procedure.
4895 (scm_environ): use environ_list_to_c. disable interrupts.
4896 (scm_convert_exec_args): take pos and subr arguments and
4897 improve error checking.
4899 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4901 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4902 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4903 argument to SCM_ASSERT. Furthermore, the name of the function
4904 should be passed as first argument when signalling
4905 SCM_WNA. (Thanks to Thomas Morgan)
4907 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4908 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4909 dispatches on the number of actual args has a default case
4910 reporting an internal error. This is a vestige from a version
4911 that mallocated a SCM vector to hold the arguments. In the
4912 current version this check is too late: if it ever happens we will
4913 have already overstepped the bounds of the array.
4915 Also, the patch [...] adds a check for too many actual arguments."
4917 mdj: Removed check for "internal programming error".
4919 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4921 * gh_io.c (gh_write): New function.
4923 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
4924 throw.c (scm_internal_stack_catch): New sibling to the other catch
4925 functions. Code moved from gh_eval.c.
4926 throw.h: Added header.
4927 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
4928 scm_internal_stack_catch.
4930 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4932 * ioext.h: fix up prototypes.
4933 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
4934 Scheme name is now dup->fdes.
4935 (scm_dup_to_fdes): make the second argument optional and
4936 fold in the functionality of scm_primitive_dup.
4937 (scm_primitive_dup): deleted.
4939 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4941 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
4942 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4943 ultrix are defined. Use setvbuf instead of setbuf.
4944 (scm_setvbuf): new procedure.
4945 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
4946 (scm_setfileno): moved from ioext.c.
4947 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
4948 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
4950 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4952 * fluids.c (scm_fluid_p): New function.
4953 * fluids.h (scm_fluid_p): New prototype.
4955 Sat Jul 26 21:33:37 1997 Marius Vollmer <mvo@zagadka.ping.de>
4957 * print.c (scm_iprin1): Enter printed structures into the print
4958 state as nested data while they are printed.
4959 (print_state_fluid, print_state_fluid_num): New variables.
4960 (scm_init_print): Initialize them.
4961 (scm_iprin): If print_state_fluid carries a print_state, use that
4962 instead of creating a new one.
4963 (scm_printer_apply, apply_stub, struct apply_data): New
4964 definitions to help with calling printer functions written in
4966 * print.h (scm_printer_apply): New prototype.
4968 * struct.c (scm_print_struct): Use scm_printer_apply to call the
4969 user defined struct printer.
4971 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
4972 * fluids.h (scm_internal_with_fluids, scm_with_fluids,
4973 scm_swap_fluids, scm_swap_fluids_reverse): New prototypes.
4974 * fluids.c (scm_internal_with_fluids, scm_with_fluids,
4975 scm_swap_fluids, scm_swap_fluids_reverse): New functions.
4977 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
4979 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
4980 SCM_ASSERT: arg comes before pos.
4982 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4984 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
4985 to a list of length zero correctly.
4987 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4989 Supply an `fgets' method for port objects to do fast line i/o.
4990 * ioext.c (scm_read_line): New function.
4991 * genio.c (scm_gen_read_line): New function.
4992 * fports.c (scm_fgets): New function.

5001 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
5003 * ioext.h: removed scm_duplicate_port prototype.
5005 * ioext.c (scm_primitive_dup2): return the new file descriptor
5006 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
5008 (scm_fdopen): bug fix: don't try to make port unbuffered until its
5009 stream has been set.
5010 (scm_duplicate_port): deleted, there's now an implementation in
5012 (scm_primitive_dup2): do nothing if newfd == oldfd.
5014 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
5016 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
5019 * ioext.h: new prototypes.
5020 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
5022 * fluids.c (next_fluid_num): don't do
5023 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
5025 * ports.h: prototypes too.
5026 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
5028 * fports.h: prototype too.
5029 * fports.c (scm_evict_ports): moved from ioext.c.
5031 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5033 * ports.c (scm_close_port): return a boolean instead of unspecified.
5034 throw an error if an error other than EBADF occurs.
5036 * filesys.h: scm_close prototype.
5037 * filesys.c (scm_close): new procedure, can close file descriptors
5038 and ports (scsh compatible).
5040 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
5043 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
5045 * fluids.c, fluid.h: New files.
5046 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
5047 (modinclude_HEADERS): Added "fluids.h"
5049 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
5050 scm_init_fluids to initialize the fluid machine.
5051 (scm_start_stack): Initialize the fluids of the first root with
5052 scm_make_initial_fluids.
5054 * root.h: Added "fluids" member to scm_root_state.
5055 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
5056 (scm_make_root): Call scm_copy_fluids to make fluid bindings
5057 unique for the new root when it has a parent.
5059 * smob.h: Include "libguile/print.h" to make scm_print_state
5062 * dynl.c (free_dynl_obj): New function to free the dynamic object
5063 data. (dynl_smob): Use it.
5064 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
5065 the dynamic object data below the linking of the object to avoid
5066 memory leak when the linking code throws an error. Now the code
5067 leaks a whole dynamically linked library when must_malloc throws,
5068 but that should be much less likely.
5070 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
5072 Changes to compile under gnu-win32, from Marcus Daniels:
5073 * stime.c (tzset): If tzset isn't provided, make it a NOP.
5074 (scm_localtime): Change SCM_EOF to SCM_EOL.
5075 (scm_mktime): Likewise.
5076 * socket.c: Don't include sys/un.h unless autoconf tells
5077 us Unix domain sockets are available.
5078 (scm_fill_sockaddr): Ignore Unix domain code.
5079 (scm_addr_vector): Likewise.
5080 (scm_init_addr_buffer): Likewise.
5081 (scm_socketpair): Don't include unless socketpair was
5082 found during autoconf.
5083 * simpos.c (SYSTNAME): Treat cygwin like Unix.
5084 * scmsigs.c (scm_pause): Don't include unless pause was found
5086 * posix.c (scm_getgroups): Don't include unless support function
5087 was found during autoconf (in this case, getgroups).
5088 (scm_setpwent): For setpwent.
5089 (scm_setegid): For setegid.
5090 * net_db.c (scm_inet_netof): Don't include unless support
5091 function was found during autoconf (in this case, inet_netof).
5092 (scm_lnaof): For inet_lnaof.
5093 (scm_inet_makeaddr): For inet_makeaddr.
5094 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.

5105 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
5106 scm_misc_error, not SCM_EOF.
5108 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
5109 arguments for formatting the error message, not SCM_BOOL_F. I
5110 think this is left over from the (eq? '() #f) days.
5112 * read.c (recsexpr): Give this a dummy definition if
5113 DEBUG_EXTENSIONS isn't #defined.
5115 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
5117 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
5120 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
5122 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
5125 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
5127 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
5128 alloca.lo will be included in @LIBLOBJS@. Something better than
5129 this should be possible.
5130 * Makefile.in: Regenerated.
5132 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
5134 * simpos.h: prototype for scm_primitive_exit.
5135 * simpos.c (scm_primitive_exit): new procedure, terminates the
5136 process without unwinding the stack.
5138 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
5140 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
5141 argument and logior its components together, so the user doesn't
5142 have to do this explicitly. Also, if regexp/basic is supplied, then
5143 turn off REG_EXTENDED.
5144 (scm_init_regex_posix): New regexp/basic symbol.
5145 (REG_BASIC): #define this if it is not already present.
5147 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5149 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
5150 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
5151 (CLEANFILES): New target, clean versiondat.h, libpath.h.
5152 (DISTCLEANFILES): New target, clean *.x.
5153 * Makefile.in: Regenerated.
5155 Tue Jun 24 00:29:07 1997 Jim Blandy <jimb@floss.red-bean.com>
5157 * script.c (scm_compile_shell_switches): Add 1997 to copyright
5158 years in usage message.
5160 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
5161 * Makefile.in: Regenerated.
5163 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
5164 flag; I don't think we support it.
5165 (scm_make_regexp): Make sure the user doesn't pass the
5168 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
5170 (scm_init_regex_posix): Define constants for the REG_mumble flags;
5171 name them according to the SCSH convention: regexp/mumble.
5173 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
5175 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
5177 * Makefile.am (libpath.h): Include the values of all the standard
5178 Makefile directory variables. Print a message, but don't print
5180 (versiondat.h): Print a message, but don't print all the commands.
5181 * load.c: #include "alist.h".
5182 (init_build_info): New function.
5183 (scm_init_load): Call it.
5184 * Makefile.in: Regenerated.
5186 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
5188 * root.c: Establish a reliable catch-all handler for the new root.
5189 After all the Scheme handler function might signal an error too,
5190 and we don't want to lose that.
5191 (cwdr_inner_body): Renamed from cwdr_body.
5192 (cwdr_outer_body): New function, to establish the user's handler,
5193 and pass control to cwdr_inner_body.
5194 (cwdr): Establish the reliable catch-all handler here, and pass
5195 control to cwdr_outer_body.
5196 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
5197 the user's handler through to cwdr_outer_body.
5198 * throw.c (scm_handle_by_message): Move guts into....
5199 (handler_message): New static function.
5200 (scm_handle_by_message_noexit): New function.
5201 * throw.h (scm_handle_by_message_noexit): New prototype.
5203 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
5204 across this. Only works on GCC. Otherwise, we hope for the best.
5205 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
5206 the feeling that real thread systems will not need this...
5208 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
5210 Try to detect when people are using one version of libguile and a
5211 different version of ice-9. People have been skewing things and
5212 sending in bug reports.
5213 * Makefile.am (versiondat.h): New file to generate.
5214 * version.c: #include "versiondat.h", to get version info.
5215 (scm_libguile_config_stamp): New function.
5216 * script.c: #include "version.h".
5217 (scm_compile_switches): Call scm_version to get version number.
5218 * scmconfig.h.in, Makefile.in: Regenerated.
5219 * Makefile.in: Regenerated.
5221 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
5222 primitive definitions under their Scheme names.
5224 * Makefile.am (libguile_la_LDFLAGS): Update library version to
5225 1:2. Helps avoid confusion between installed and uninstalled libs.
5227 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
5230 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
5231 backslash from definition; this should be used like: GDB_INTERFACE;
5233 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5235 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
5236 new port unbuffered until its stream has been set.
5238 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
5240 * ports.h: new prototype.
5241 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
5243 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
5245 Make things compile neatly under Sun's C compiler.
5246 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
5247 * extchrs.c (xmbtowc): Make the second arg a normal char, not
5248 unsigned, because that's what the ANSI function takes.
5249 * extchrs.h (xmbtowc): Corresponding change to prototype.
5250 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
5252 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
5253 argument plain char *.
5254 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
5256 * tag.c (scm_tag): Remove unreachable statement.
5257 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
5258 top of the word, it should be unsigned.
5260 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
5261 is defined, to avoid warnings; it's only used in the
5262 conflict-checking code. Which might go away anyway.
5263 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
5264 conditionals; put the label definition in an #if too, to stifle
5267 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
5268 ChangeLog-threads in the distribution.
5269 * Makefile.in: Regenerated.
5271 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5273 * guile-snarf.in: Changed regexp to support CPPs that insert
5274 whitespace between lexical tokens (which munges the `%%%' snarf
5277 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5279 * load.c (scm_init_load_path): Append $(datadir)/guile to
5280 %load-path, so modules do not have to be installed in Guile's
5281 current version directory.
5283 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
5285 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
5286 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
5287 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
5288 call the sysdep functions with deferred ints.
5289 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
5290 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
5291 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
5294 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
5297 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
5299 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
5301 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
5303 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
5306 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
5308 * eval.c (scm_lookupcar1): New procedure to cope with a race
5309 condition during lookup (when using threads).
5310 (scm_lookupcar): Implement in terms of scm_lookupcar1.
5311 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
5314 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
5316 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
5317 supplied. (Change from Tim Pierce.)
5319 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
5321 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
5322 23:47:01 1997" changelog: Slots are now initialized with `#f' by
5323 default and not `()'. `#f' is the canonical non-value in Scheme,
5326 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5328 * struct.c (struct_printer): New variable that holds a handle on
5329 the Scheme variable *struct-printer*. This variable can be set by
5330 Scheme code to override the printing of structures.
5331 (scm_print_struct): If struct_printer is set, call it. If it is
5332 not set, or returns #f, print the structure in the old fashion.
5333 Include "eval.h" for scm_apply.
5335 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
5337 * struct.c (scm_struct_ref, scm_struct_set_x): Use
5338 scm_struct_i_n_words to get the number of fields, not
5339 -scm_struct_n_extra_words.
5341 On the route to fancier struct printing:
5342 * struct.c (scm_print_struct): New function to print a structure.
5343 Include "genio.h" to support it. This function doesn't do
5344 anything interesting right now, but I think it should be here
5346 * struct.h: Include "print.h" and add prototype for
5348 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
5349 print structures ourself.
5351 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5353 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
5354 before applying the handler in case it doesn't return.
5356 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
5358 * scmsigs.h, async.h: updated.
5360 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
5363 * posix.c (scm_uname): interpret only negative values as an error.
5364 Solaris normally returns a positive value.
5366 * script.c (scm_compile_shell_switches): if we are not going into
5367 an interactive repl, set scm_mask_ints to zero so that asyncs can
5370 * simpos.c (scm_system): don't ignore/unignore signals around
5373 * posix.c (scm_open_pipe): don't ignore/unignore signals around
5376 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
5377 done in boot-9.scm instead.
5379 * scmsigs.c, async.c: Major rewriting of signal handling code.
5380 (scm_sigaction): new procedure.
5381 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
5383 (scm_raise): return unspecified, throw error on failure.
5385 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5387 * regex-posix.c (scm_init_regex_posix): Register the "regex"
5388 feature, to help boot-9.scm decide whether to import the regex
5391 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5393 * eval.c: Include scmconfig.h at the beginning of the file so that
5394 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
5397 * regex-posix.c: #include "_scm.h" before conditionally #including
5398 <regex.h>; the former defines HAVE_REGCOMP.
5400 * regex-posix.c: #include <regex.h> conditionally, so the file is
5401 CPP'able (for dependency scanning) even on systems that don't have
5404 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5406 Add new R4RS-compliant syntax for keywords.
5407 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5408 regardless of the setting of the `keywords' read option.
5409 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5410 can be re-read no matter what the setting of the `keywords' read
5413 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5415 Add support for POSIX regular expressions.
5417 * regex-posix.c, regex-posix.h: New files. (Some code
5418 is taken liberally from rx/rgx.c in the old Guile dist.)
5420 * init.c: Include regex-posix.h.
5421 (scm_boot_guile_1): Call scm_init_regex_posix.
5423 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5424 Add regex-posix.[ch] sources.
5425 * Makefile.in: Regenerated.
5427 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5428 to do this automatically? It didn't for me, bleh.)
5430 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5432 * fports.c (print_pipe_port): New function.
5433 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5434 latter doesn't even take the right arguments.
5436 * Makefile.am: Increment shared lib revision number. I think
5437 sometimes the uninstalled Guile finds the installed shared lib;
5438 Gord says doing this might help. As things turned out, I can't
5439 say whether it does.
5440 * Makefile.in: Regenerated.
5442 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5443 passing it as the closure argument to scm_boot_guile. (Bill
5446 * ports.c (print_void_port, putc_void_port, puts_void_port,
5447 write_void_port, flush_void_port, getc_void_port, close_void_port,
5448 noop0): Use ANSI prototypes instead of K&R declarations, so the
5449 initialization of void_port_ptob gets aggressively type-checked.
5450 Fix arguments of print_void_port and write_void_port. (Bill

5484 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5486 * script.c (scm_find_executable): Use prototype-style definition
5487 here; apparently it's not quite right to have const in a prototype
5488 and then use a K&R declaration. I wonder if stuff like this will
5489 go away if we compile with -Wrequire-prototypes, or whatever that
5490 is... (Bernard URBAN)
5492 * scmhob.h: New text from Bernard URBAN.
5494 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5496 * script.c: Don't #define const on hpux. Configure takes care of
5497 this. (Thanks to Larry Schwimmer.)
5499 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5500 decide whether to #include <unistd.h>, instead of listing a bunch
5501 of systems. Don't #include stdio twice. Removed dyked-out
5502 definition of scm_find_impl_file.
5504 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5506 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5507 library version info to 1:0.
5508 * Makefile.in: Regenerated.
5510 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,
5511 gdb_interface.h, gdbint.c, gdbint.h, gh_data.c, gh_init.c,
5512 gh_io.c, gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c,

5514 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5515 throw.c: Update copyright years; these files have been worked on
5516 significantly in 1997, but only had copyright years for 1996.
5517 Also, change name of copyright holder on some from Mikael
5518 Djurfeldt to Free Software Foundation; he has signed papers
5519 assigning the changes to the FSF.
5521 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5522 reason not to give the user the option.
5524 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5525 Return #f on end-of-file when scanning table (i.e. when called
5526 with no arguments). Try to catch errors, when we can.
5527 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5529 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5530 external declarations. These are useful.
5532 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5534 * posix.c: don't include <sys/select.h> or define macros for
5535 select, since they were not used in this file.
5537 * filesys.c (scm_select): make the fifth parameter microseconds,
5538 not milliseconds. let the fourth parameter be either a real value
5539 or an integer or #f. The first, second and third arguments can
5540 now be vectors: the type of the corresponding return set will be
5542 (set_element, get_element): new static procedures.
5544 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5546 * strports.c (scm_eval_string): New function.
5547 (scm_eval_0str): Trivially re-implemented in terms of
5549 * strports.h (scm_eval_string): New extern decl.
5551 * net_db.c (h_errno): Add extern decl for this.
5553 * fports.c (local_pclose): New function.
5554 (scm_pipob): Use it in the initializer here.
5557 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5558 Use a meaningful error message when signalling an error. For
5559 this, scm_gethost must check h_errno rather than errno.
5561 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5563 * Makefile.in: Regenerated, using automake-1.1p.
5565 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5567 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5568 not SCM_UNSPECIFIED.
5570 * script.c (scm_compile_shell_switches): don't append (quit) if
5572 (scm_shell): call scm_exit_status and exit on the result of the
5575 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5577 Ensure that shared substrings are handled properly when passed to
5578 a system call or other foreign function. Many thanks to Tim
5580 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5581 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5582 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5583 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
5584 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
5585 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5586 (scm_display_error_message): use RO macros when strings may be RO.
5587 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5588 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5589 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
5590 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
5591 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
5592 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
5593 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
5594 scm_strftime), vports.c (scm_make_soft_port): use
5595 SCM_COERCE_SUBSTR to make sure shared substrings are
5598 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5600 * error.c (scm_error): Add newline to error message.
5602 * init.c (scm_init_standard_ports): Doc fix.
5604 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5606 * dynl-shl.c: Completely replaced with new code from Bernard
5609 * script.c (scm_ice_9_already_loaded): New variable.
5610 (scm_compile_shell_switches): Use it.
5612 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5614 * filesys.c (scm_input_waiting_p): add missing third argument to
5617 * stime.c (scm_localtime): copy the result of localtime before
5618 calling gmtime in case they share a buffer.
5619 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5622 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5624 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5626 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5628 * Makefile.am (check-local): New target, which causes 'make check'
5629 to run gh_test_c and gh_test_repl, with some trivial input.
5630 * Makefile.in: Rgnrtd.
5632 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5634 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5637 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5639 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5640 sure how this was supposed to work.
5641 (scm_async_click): don't send SCM_TICK_SIGNAL.
5642 (scm_init_async): don't initialize %tick-thunk.
5644 * the following change doesn't affect the Scheme interface:
5645 gc-thunk is called at the end of garbage collection. however it's
5646 no longer implemented by pretending it's a signal.
5648 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5649 system async corresponding to scm_gc_thunk.
5650 * async.h: declare scm_gc_async.
5651 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5652 gc-thunk directly, instead of going through a signal handler.
5653 (scm_gc_async): new variable, points to the GC system-async.
5654 (scm_init_async): save the GC async as scm_gc_async instead
5655 of using system_signal_asyncs.
5656 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5658 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
5660 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
5661 Don't screw up if we're interrupted.
5662 * Makefile.in: Regeneradet.
5664 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5666 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5668 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5669 we're not using AM_INIT_GUILE_MODULE any more.
5670 * Makefile.in: Reneregated.
5672 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5674 Functions for finding variable bindings, grace à Tim Pierce.
5675 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5676 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5678 Get 'make dist' to work again.
5679 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5680 * Makefile.in: Regenerated, like a surry without a fringe on top.
5682 Changes for reduced Guile distribution: one configure script,
5684 * configure.in, configure: Removed.
5685 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5686 real configure script lives.
5687 * Makefile.in, scmconfig.h.in: Regenerated.
5689 * init.c: #include "script.h", to get prototype for script.c's
5692 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5694 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5695 scm_must_malloc, not raw malloc.
5697 * script.c (scm_compile_shell_switches): Dyke out debugging output
5700 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5702 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5704 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5705 system has them. Hope this is safe. Previously
5706 sys/timeb.h was included if HAVE_FTIME was defined or if
5707 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5708 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5710 * ioext.c (scm_setfileno): add missing third argument to
5711 scm_misc_error call.
5713 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5715 * eq.c (scm_equal_p): Correctly compare strings of different
5716 varieties. (Thanks to Tim Pierce.)
5718 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5720 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5721 #! block comment must occur on a line all by itself.
5723 Move most of the guts of shell command processing into libguile,
5724 so guile.c can be very small (and eventuallly auto-generated. (I
5725 mean, generated mechanically, not self-generated. Hmm.))
5726 * guile.c, script.c, script.h: New source files.
5727 * init.c (scm_boot_guile_1): Call scm_init_script.
5728 * libguile.h: #include "script.h".
5729 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5730 targets, for new executable.
5731 (libguile_la_SOURCES): Mention script.c.
5732 (modinclude_HEADERS): Add script.h.
5733 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5734 not dynamic linking is enabled. This is because we're generating
5735 executables now. Move CY_AC_WITH_THREADS call after those, so the
5736 values of cy_cv_threads_libs captures the libs chosen above.
5737 * Makefile.in, configure, aclocal.m4: Regenerated.
5739 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5740 We don't maintain this interface any more, and it just confuses
5743 * alloca.c: #include <scmconfig.h>, not <config.h>.
5744 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5745 it'll get included in disties.
5747 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5749 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5750 be distributed, because they confuse people.
5751 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5753 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5755 * configure.in: check for presence of gethostent (not present on
5756 OpenBSD by default).
5757 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5758 * configure, scmconfig.h.in: Regenerated.
5760 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5762 * backtrace.c (scm_backtrace): Split message string across
5763 newlines properly. GCC is more tolerant of this than other
5766 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5768 Merge threads directory into libguile.
5769 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5770 threads.h: New source files.
5771 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
5772 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5774 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5775 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5776 coop-threads.c.cygnus, coop-threads.h.cygnus.
5777 * configure.in: If we're using threads, include threads.o in
5779 * _scm.h, libguile.h: threads.h lives in this directory now.
5780 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5781 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5782 currently used, but brought along for information's sake.
5783 * ChangeLog-threads: log from old 'threads' directory.
5784 * Makefile.in, configure: Rebuilt.
5786 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5788 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5791 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5793 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5795 Merge GH interface library into libguile.
5796 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5797 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5798 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5799 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5801 (EXTRA_libguile_la_SOURCES): ... here.
5802 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5803 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5804 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5805 New variables, describing how to build the gh test programs.
5806 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5807 build the test programs, and we probably should have been linking
5808 libguile.la against them all along, to support AIX shared libs.
5809 Add cflags for threads to CFLAGS; add libs for threads to new
5810 variable THREAD_LIBS, used in Makefile.am.
5811 * ChangeLog-gh: log from old `gh' subdirectory.
5812 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5814 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5816 * acconfig.h: Undo change of Apr 9; including the definition of
5817 PACKAGE in the guile headers conflicts with applications' own
5819 * scmconfig.h.in: Regenerated.
5821 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
5823 * filesys.c (scm_fcntl): New function from Roland McGrath.

5825 * filesys.h: Added prototype.
5827 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
5828 when PROC is receiving no arguments.
5830 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5832 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5833 have S_IFSOCK. This is the case under Ultrix.
5835 * posix.c (scm_status_exit_val, scm_status_exit_val,
5836 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5837 Ultrix versions of WIFSTOPPED, etc., which assume that their
5838 arguments are lvalues (hmm).
5840 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5842 * eval.c: Doc fixes.
5844 * throw.c: Doc fixes; rearranged.
5846 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5848 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5850 * acconfig.h: Added entry for PACKAGE.
5851 * scmconfig.h.in: Regenerated.
5853 Changes to work with automake-1.1n, which has better libtool support.
5854 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5855 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5857 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5859 * Makefile.in: Rebuild.
5861 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5863 * stime.c (scm_mktime): take an optional zone argument.
5864 (scm_localtime): check putenv return value.
5865 (scm_strftime, scm_strptime): moved from posix.c. move #include
5867 stime.h, posix.h: update prototypes.
5868 (bdtime2c, setzone, restorezone): new static procedures.
5869 (scm_mktime, scm_strftime): use them.
5870 (scm_strftime): don't call mktime before strftime. Use
5871 filltime for return value.
5872 (filltime): convert NULL zname to #f.
5873 (scm_strptime): return a count of characters consumed, not
5874 the remaining string.
5876 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5878 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
5879 (scm_mktime): likewise.
5881 Uncomment localtime and mktime.
5883 * configure.in: add AC_STRUCT_TIMEZONE.
5885 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5887 * stime.c (scm_init_stime): don't define ticks/sec.
5888 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5889 return value problem and is still portable.)
5891 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5893 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5894 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5895 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5896 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5897 cpp_err_symbols.c): Corresponding changes.
5898 * Makefile.in: Regenerated.
5900 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5902 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5903 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5904 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5905 * putenv.c: new file, from sh-utils 1.12.
5907 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5908 since allocation isn't for Scheme objects.
5909 (scm_putenv): copy strings before placing in the environment.
5911 * stime.c (scm_current_time): throw an error if time returns -1,
5912 instead of returning #f.
5913 (scm_get_internal_real_time, scm_get_internal_real_time): use
5914 scm_long2num for return value instead of SCM_MAKINUM.
5916 * stime.h: prototypes updated.
5918 * stime.c (scm_time_in_msec): apparently unused, deleted.
5920 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5922 * configure.in: check for gettimeofday.
5924 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5925 which may be more usefully portable than a gettimeofday interface.
5927 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5929 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5931 * Makefile.in: Regenerated.
5933 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5935 * stime.c (filltime): recovered static procedure.
5936 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5939 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5940 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5942 * posix.c (scm_mknod): split the mode argument into type and perms
5943 arguments, like the extra fields returned by stat.
5945 * fports.c (scm_pipob): set the close, free and print procedures.
5946 (scm_close_pipe): new procedure.
5948 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5949 define them in boot-9.scm
5951 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5953 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5954 wan't defined. Don't include fd.h.
5956 * Previously fd.h was regenerated whenever configure was run,
5957 forcing a couple of files to be recompiled.
5959 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5960 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5961 Check for _fileno as well as _file.
5963 * ioext.c: don't fd.h.
5964 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5967 * Change the stratigy for getting information about errno
5968 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5969 generating lists of symbols during the build process, which will
5970 not always work, include comprehensive lists in the distribution.
5971 To help keep the lists up to date, the "check_signals" and
5972 "check_errnos" make targets can be used.
5974 * configure.in: don't check for a command to extract errno codes.
5975 * Makefile.am: update file lists, remove errnos.list and errnos.c
5976 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5977 check_errnos targets.
5978 (CLEANFILES): remove errnos.c and errnos.list, add
5979 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5980 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5981 * errnos.default: deleted.
5982 * cpp_signal.c: new file.
5983 * cpp_errno.c: renamed from errnos_get.c.
5984 * cpp_err_symbols, cpp_sig_symbols: new files.
5985 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5986 * error.c (scm_init_error): #include cpp_err_symbols instead of
5988 * posix.c (scm_init_posix): don't intern signal symbols. #include
5991 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5993 * strop.c (scm_i_index): allow the lower bound to be equal to the
5994 length of the string, so a null string doesn't always give an error.
5996 * posix.h: new prototypes.
5997 * posix.c (scm_status_exit_val, scm_status_term_sig,
5998 scm_status_stop_sig): new functions, as in scsh. They break down
5999 process status values as returned by waitpid.
6001 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
6003 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
6004 configure doesn't know about it.
6006 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6008 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
6010 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
6011 which defines C variables with global linkage.
6013 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6015 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
6018 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
6020 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
6021 has time to check why this doesn't work well with continuations.
6023 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
6025 * Fix shell syntax error; some shells won't tolerate
6026 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
6028 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
6030 * posix.c (scm_uname): throw an error if uname fails instead
6033 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
6035 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
6038 * async.c (scm_ints_disabled): definition moved from error.c.
6040 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6042 * acconfig.h: Removed PACKAGE.
6044 * scmconfig.h.in: Regenerated.
6046 * snarf.h: g++ says it's non-portable not to specify the first
6047 argument in a varargs declaration. I introduced the first
6048 argument by using preprocessor conditionals.
6050 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
6052 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
6053 (scm_freopen): use RO string macros for filename and modes.
6054 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
6056 * posix.c (scm_getgrgid): simplify conversion of name to C string.
6057 (scm_mknod): use RO string macros for path.
6059 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
6060 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
6062 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
6063 use SCM_ROSTRINGP and SCM_ROCHARS.
6065 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6067 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
6070 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
6071 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
6072 support for byte vectors.
6074 * print.c (scm_iprin1): Limit number of vector elements printed
6075 according to pstate->length.
6077 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6079 * backtrace.c (scm_display_error_message): don't segv if message
6082 * error.h: prototype for scm_error_scm.
6084 * error.c (scm_error_scm): new procedure, reimplements scm-error
6085 in C and uses scm_error.
6087 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6089 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
6090 pointer to the Scheme variable read-hash-procedures and intern it
6091 in scm_init_read. Modify scm_read_hash_extend and
6092 scm_get_hash_procedure to use the pointer.
6094 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6096 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
6097 (SCM_KEYWORD_STYLE): defined.
6099 * read.c (scm_read_opts): add a keywords option. This isn't a
6100 boolean option, in case someone wants to add support for DSSSL
6102 Setup scm_keyword_prefix symbol.
6103 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
6105 I've left keyword support disabled by default, since it doesn't
6106 seem to break the module system and it gives R4RS standard behaviour.
6107 It can be reactivated with (read-set! keywords 'prefix).
6109 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6111 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
6112 before constructing arbiter.
6114 * eval.c (scm_m_define): Bugfix: Check that the object is a
6115 closure before setting the procedure property!
6117 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
6119 * ports.c: Removed `ungetc-char-ready?'.
6121 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
6123 * read.c (scm_init_read): intitialise scm_read_hash_procedures
6124 (idea from Mikael: make it a pair so scm_permanent object only
6126 (scm_read_hash_extend): don't call scm_permanent_object.
6127 (ideas from Mikael): if chr is already in the list, replace its
6128 procedure instead of appending it again. If proc is #f, remove
6130 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
6132 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
6134 * gdbint.c (gdb_read): update scm_lreadr usage.
6136 * load.h: update prototypes.
6138 * load.c (scm_primitive_load, scm_read_and_eval_x,
6139 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
6141 * read.h: add prototype for scm_read_hash_extend. Change args for
6144 * read.c (scm_read_hash_procedures): new variable.
6145 (scm_read_hash_extend): new procedure.
6146 (scm_get_hash_procedure): new procedure.
6147 (scm_lreadr): use scm_get_hash_procedure instead of an argument
6148 for extended # processing.
6149 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
6150 scm_read_token): remove case_i, sharp arguments. Change callers.
6152 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
6154 * read.h (SCM_N_READ_OPTIONS): increase to 3.
6155 (SCM_CASE_INSENSITIVE_P): define.
6157 * read.c: add case-insensitive option to scm_read_opts.
6158 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
6159 to determine whether to convert symbol case.
6160 (default_case_i): definition removed.
6161 * read.c (scm_read_token): if case_i, downcase ic before doing
6164 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6166 * configure.in: Added configuration option `guile-debug'.
6167 Configure with --enable-guile-debug if you want a bunch of extra
6168 functions used for debugging when developing Guile.
6170 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
6172 * procs.c (make-cclo): New undocumented debugging procedure: Make
6173 compiled closure with internal procedure PROC and length LENGTH.
6174 Only compiled if GUILE_DEBUG is defined.
6176 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
6178 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
6180 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
6182 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
6183 with 3 or more args internally to the evaluator.
6185 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6187 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
6188 with 3 or more args internally to the evaluator. This is mainly
6189 because we don't want to pass entry and exit points of the
6190 debug support twice, but it also seems to increase the speed of
6191 the evaluator for such calls (e. g. (+ 1 2 3)).
6193 * backtrace.c (scm_display_application): New procedure:
6194 display-application; Set fancy printing parameters individually
6195 for different types of display (backtrace, error, application).
6196 (These should of course be customizable!)
6198 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
6199 clear the CHECK-flags.
6201 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6203 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
6205 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6207 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
6208 from pairs with a GLOC in the car.
6210 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
6211 otherwise `symbol-hash' will behave badly.
6212 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
6213 we get segmentation fault!
6215 * symbols.c: Added #include "weaks.h". New functions:
6216 `builtin-bindings' and `builtin-weak-bindings'. (These will be
6217 moved to an extraneous library when we split libguile.)
6219 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6221 * filesys.c (scm_stat): stat now takes fport arguments too as
6222 documented in the manual.
6224 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6226 * debug.c (scm_single_step): Bugfix: Call continuation with
6227 scm_call_continuation instead of throwing to it.
6229 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
6231 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
6232 argument wasn't declared to be optional.
6234 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6236 * stime.c (scm_init_stime): Add feature "current-time".
6238 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6240 * throw.h: prototype for scm_exit_status.
6241 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
6242 args to derive an exit status. Allows (quit) to work from a
6244 (scm_exit_status): new function.
6247 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6249 * eval.c (scm_deval): Removed some old code.
6250 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
6252 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
6255 * symbols.c (msymbolize): Bugfix: Must initialize property list to
6258 * procs.c: Introduce the existent C function scm_thunk_p at the
6259 Scheme level as well.
6261 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6263 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
6264 used from C to easily lookup the value of a symbol in the current
6267 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6269 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
6270 scm_init_unif in this file. This will also fix a previous problem
6273 * configure.in: Added AM_MAINTAINER_MODE
6275 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6277 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
6280 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6282 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
6283 source files that are not always included in libguile but should
6284 have their dependencies calculated by automake. This variable is
6285 recognized by automake, no further magic is needed.
6286 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
6287 to deal exclusively with *.lo files, as it seems. The *.o files
6288 are built automatically when the corresponding *.lo file gets
6291 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
6293 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
6296 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
6298 * unif.c (scm_array_set_x): minor change to argument error checking.
6300 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
6302 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
6303 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
6304 They should only be included in the library at configure.in's
6306 (libguile_la_LDADD): Include the appropriate .lo files here.
6307 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
6308 so we know when to build them (and their .lo bretheren).
6309 * configure.in (LIBLOBJS): New substituted variable. We let
6310 configure decide which .o files to include in LIBOBJS, and then
6311 put the corresponding list of .lo files in LIBLOBJS. The latter
6312 is what we pass to libtool.
6313 * Makefile.in, configure: regenerated.
6315 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
6317 * symbols.c (scm_sysintern0): New function. Contains the core of
6318 old scm_sysintern but doesn't take a second value argument.
6319 (scm_sysintern): Now uses scm_sysintern0.
6320 (scm_sysintern_no_module_lookup): Renamed to
6321 scm_sysintern0_no_module_lookup and doesn't take a second value
6322 argument any longer.
6324 * symbols.h (scm_sysintern0: Added declaration.
6326 * options.c (scm_init_opts): Use scm_sysintern0 instead of
6327 scm_sysintern when interning option keys. Otherwise we risk
6328 destroying the values of already interned variables.
6330 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
6331 scheme-level boolean (use SCM_NFALSEP).
6333 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
6335 (scm_backtrace): New function. (C version of old function from
6336 boot-9.scm) Motivation: Make it possible to display backtraces
6337 without depending on boot-9.scm. (I'm uncertain if this
6338 motivation is good enough...)
6340 * root.h (scm_root_state): Add member the_last_stack_var.
6341 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
6343 * root.c (mark_root): Mark scm_the_last_stack_var.
6345 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
6348 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
6350 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
6351 1. mark_lazy_catch didn't mark the smob.
6352 2. Both functions above have standard variants:
6353 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
6354 free_lazy_catch --> scm_free0.
6356 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
6358 * throw.c (scm_internal_lazy_catch): New function.
6359 (scm_lazy_catch): Rewritten to use it.
6360 (scm_ithrow): Handle the new lazy catch representation.
6361 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
6362 that doesn't have a jmpbuf is a lazy catch clause.
6363 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
6364 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
6365 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
6367 (scm_init_throw): Register the new lazy-catch smob type.
6368 * throw.h (scm_internal_lazy_catch): decl for new function.
6370 * throw.c (scm_internal_catch): Doc fixes.
6372 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
6373 configure.in. Including this might cause problems if applications
6374 that link against libguile include their own copies of alloca, but
6375 if they're using autoconf, they should be adding libguile to LIBS
6376 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
6377 the copy in libguile, and things will be okay. (I think.)
6379 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6381 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
6383 strop.h: move prototypes too.
6385 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6387 * posix.c (scm_init_posix): don't intern EINTR since it's now done
6390 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
6391 etc. I deleted them from filesys.c long ago, but didn't
6392 notice they were here too (although ineffective since
6393 sys/stat.h wasn't included).
6395 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
6397 * eval.c: Don't define alloca in GCC case. gcc will automatically
6398 use __builtin_alloca if appropriate.
6400 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6402 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6403 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6404 that values of automatic variables are preserved. See comments
6405 for safe_setjmp for details.
6407 Change from Thomas Morgan:
6408 * variable.c: Include eq.h.
6409 (var_equal): New function.
6410 (variable_smob): Use var_equal as the discriminator for variables.
6412 * throw.c (s_throw): Remove extraneous declaration.
6414 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6415 * eval.c: Add necessary CPP cruft to support that.
6416 * configure, Makefile.in, scmconfig.h.in: regenerated.
6418 Change from Thomas Morgan:
6419 * procprop.c (scm_procedure_properties): Convert the Scheme
6420 boolean returned by scm_procedure_p into a C boolean before using
6421 it as a condition for SCM_ASSERT.
6422 (scm_procedure_property): Likewise.
6424 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6425 indications of Unixness.
6428 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6430 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6432 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6434 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6435 "unknown # object" error messages.
6437 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6438 (scm_i_index) and declare it static. Add a 'direction' argument
6439 to indicate what way the search should go.
6440 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6442 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6443 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6445 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6447 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6449 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6450 to avoid clash with various scsh forks.
6452 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6454 The following two changes (ramap.c, throw.c) are motivated by the
6455 apparent unportability of forward declarations of static arrays of
6456 the form `static foo bar[];'.
6458 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6459 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6461 * throw.c (scm_throw): Moved above scm_ithrow.
6463 * options.h: Removed the extern declarations of scm_yes_sym and
6464 scm_no_sym since these are static.
6466 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6468 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6470 * Makefile.am: remove AWK=@AWK@.
6471 Add a rule for generating errnos.list.
6472 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6474 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6475 don't extract errnos, just set a variable (avoids the
6476 need to recompile error.c just because configure is run.)
6478 * unif.h: update prototypes.
6479 * unif.c (scm_uniform_array_read,write): change the offset and
6480 length arguments to start and end, for consistency.
6482 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6484 * ioext.h: update prototypes.
6485 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6486 scm_read_line_x, it's a more general procedure using an
6487 interface from scsh. read-line and read-line! are now defined
6489 Note that the new read-line trims the terminator
6490 by default, previously it was appended to the returned string. An
6491 optional argument specifies how to process the terminator (scsh
6492 compatible). For the old behaviour: (read-line port 'concat).
6493 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6494 returns a pair, but is converted to multiple values if the scsh
6497 socket.h: update prototypes.
6498 * socket.c (scm_recvfrom): for consistency with other procedures,
6499 take start and end as separate optional arguments.
6500 (scm_recv, scm_recvfrom): don't allow the second argument
6501 to be a size, only a buffer. Change the scheme names to
6502 recv! and recvfrom!. Don't return the buffer.
6504 * ioext.h, posix.h: move prototypes too.
6505 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6506 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6507 "read.h" and "unif.h".
6508 * ioext.c: include "chars.h"
6510 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6512 * dynl.c: The dynamic linking and module registration functions
6513 are now defined even when dynamic linking is not available for the
6514 host system. Some of their functionality can be done without
6515 dynamic linking; when it's really needed, they throw errors.
6517 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6519 * configure.in: Only define DYNAMIC_LINKING when one of the system
6520 dependent functions is detected.
6521 * dynl.c (scm_dynamic_func): New function to get the address of a
6522 function in a dynamic object.
6523 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6524 produced by scm_dynamic_func as the thing to call.
6526 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6528 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6529 (scm_register_module_xxx, scm_registered_modules,
6530 scm_clear_registered_modules): New functions.
6532 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6534 * symbols.c (scm_sysintern): Renamed to
6535 scm_sysintern_no_module_lookup.
6536 (scm_sysintern): New function to take the place of the old
6537 scm_sysintern. It uses the current toplevel lookup closure to give
6538 the symbol its value. This is a temporary hack to put packages
6539 like gtcltk into their own module.
6540 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6541 us whether `scm_top_level_lookup_closure_var' has been initialized
6543 * eval.c (scm_init_eval): Set it.
6545 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6547 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6548 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6550 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6552 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6553 scm_sys_dup): deleted: FD capability will be added to other
6555 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6556 scm_fd_free, fd_smob, scm_intern_fd.
6557 (scm_open): renamed from scm_sys_open. Return a port instead of
6558 an FD object. Make the mode argument optional.
6559 (scm_sys_create): deleted, it's just a special case of open.
6560 (scm_init_filesys): move interning of constants O_CREAT etc.,
6561 here (were previously using SCM_CONST_LONG macro).
6562 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6564 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6565 include "fports.h" and <stdio.h>
6566 (scm_stat, scm_select): don't support FD objects.
6568 * error.h: adjust scm_syserror_msg prototype.
6569 * error.c (scm_syserror_msg): take an extra argument for errno.
6570 Using the global value didn't always work, since it could be
6571 reset by procedure calls in the message or args arguments.
6573 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6574 I don't understand why the check was there (and what about the
6577 * strop.c (scm_string_copy): allow shared substrings to be copied.
6579 * unif.h: corresponding change to prototypes.
6580 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6581 recognize two new optional arguments: offset and length. Allow
6582 the port argument to be an integer (file descriptor, for scsh).
6583 Include <unistd.h> for "read" prototype.
6585 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6587 * socket.c: don't include filesys.h.
6589 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6591 * Makefile.am: add AWK=@AWK@ (?)
6593 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6595 Add a rule to generate errnos.c from errnos.
6596 * error.c (scm_init_error): include errnos.c.
6597 * errnos_cnvt.awk: new file, converts the list of errno codes to
6599 * errnos_get.c: new file.
6600 * errnos.default: new file, contains errnos to try if they can't
6601 be extracted from errno.h.
6602 * configure.in: if using GCC, try and extract errno codes from
6606 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6608 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6609 * Makefile.am: Made libguile into a libtool library.
6610 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6611 Set libtool_libs to indicate that libguile is a libtool library.
6612 See guile/ChangeLog for details.
6613 * .cvsignore: ignore "*.lo", the libtool library objects.
6615 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6617 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6618 use htons in getservbyport argument.
6620 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6622 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6623 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6626 * objprop.c (scm_object_property): No need to take the CDR of the
6627 value returned by scm_object_properties, since Aug 20 change.
6629 * configure.in: When checking for struct linger, #include
6630 <sys/types.h> as well as <sys/socket.h>. I've never known
6631 <sys/types.h> to cause any portability problems, and Solaris's
6632 <sys/socket.h> needs it.
6633 * configure: Rebuilt.
6635 I think the Sun compiler has chosen a perverse way to interpret
6636 ANSI declarations combined with K&R definitions. We'll
6637 appease it a little bit. But when it invades France, we fight.
6638 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6639 * print.h (scm_iprlist): Here too.
6640 * numbers.c (scm_divbigdig): Change definition to match
6641 declaration in numbers.h.
6642 * unif.c (scm_makflo): Change definition to match declaration in
6645 * init.c (scm_boot_guile): Don't return the value of
6646 scm_boot_guile_1. This function doesn't return a value;
6647 scm_boot_guile_1 doesn't return a value (or return at all).
6649 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6652 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6653 compile. I have a feeling this function is a bad idea anyway ---
6654 one should always test for features, not systems.
6656 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6657 semicolons. Only pure luck kept this from being noticed earlier.
6659 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6661 * socket.c (scm_recvfrom): Added missing semicolon.
6663 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6665 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6666 the buffer and start and end positions for scsh networking
6669 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6671 * configure.in: Revert previous change to this file; the problem
6672 is due to transient automake weirdness.
6673 * configure: Rebuilt.
6675 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6676 PLUGIN/guile.libs. configure generates the latter from the former.
6677 * Makefile.in: Rebuilt.
6679 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6680 need this if we install scripts, like guile-snarf.
6681 * configure: Rebuilt.
6683 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6685 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6687 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6689 * socket.c (scm_addr_vector): fix faulty scm_listify.
6691 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6693 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6694 style block comment is no longer considered an error.
6696 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6698 * PLUGIN/guile.libs.in: New file.
6699 * PLUGIN/guile.libs: Removed from repository.
6700 * configure.in: Create PLUGIN/guile.libs from
6701 PLUGIN/guile.libs.in. This is for including additonal libraries
6702 needed for dynamic linking.
6703 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6704 instead of PLUGIN/guile.libs.
6706 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6708 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6710 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6711 occurrences of the given element from the list, not just the
6712 first. This is how the Emacs Lisp functions behave, how the
6713 analogous Common Lisp functions behave, and (I believe) how the
6714 older Maclisp functions worked. I realize that this change may
6715 break code, but it seemed better to break it before the Guile
6718 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6719 Their prototypes were already present in gc.h, but they weren't
6721 (scm_init_storage): Initialize scm_protects.
6722 * root.c (scm_protects): New element of scm_sys_protects.
6724 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6726 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6728 * libguile.h: Added #include "libguile/net_db.h".
6730 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6731 30 change. That file is only meant for communication between the
6732 configuration process and load.c. If code linked against libguile
6733 wants to get at the paths mentioned in libpath.h, it can call
6734 functions declared in load.h.
6736 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6738 * libguile.h: Removed #include "libguile/fdsocket.h"
6740 * net_db.c: Added #include <sys/socket.h>.
6742 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6744 * filesys.c (scm_input_waiting_p): use select in preference to
6745 FIONREAD, since the latter doesn't detect EOF.
6746 Throw error if neither select nor FIONREAD available.
6748 * socket.c (scm_connect): take a port, not a fd object.
6749 (scm_fill_sockaddr): throw an error if fam is not recognised.
6750 (scm_bind): use scm_fill_sockaddr.
6751 (scm_listen): take a port, not a fd object.
6752 (scm_accept): take and return a port. return #f in the car if
6753 address can't be got
6754 (scm_sock_fd_to_port): new procedure.
6755 (scm_socket): use scm_sock_fd_to_port.
6756 (scm_addr_vector): throw error if unrecognised address type.
6757 take an extra argument with the calling procedure name.
6758 (scm_getsockname): take a port. return #f if address can't be got.
6759 (scm_getpeername): take a port. return #f if address can't be got.
6760 (scm_recvfrom): take a port. return #f for address component if can't
6762 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6763 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6765 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6767 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6768 use separate data pointers, to allow them to be designed
6769 independently and reused.
6770 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6771 Renamed from catch_body, catch_handler, and uncaught_throw; made
6773 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6775 (scm_catch): Use the above.
6776 (scm_throw): Don't bother printing a message for an uncaught
6777 throw; we establish a default handler in init.
6778 * throw.h (scm_internal_catch): Prototype updated.
6779 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6781 (struct scm_body_thunk_data): New structure, used as data
6782 argument to scm_body_thunk.
6783 * init.c (struct main_func_closure): New structure, packaging up
6784 the data to pass to the user's main function.
6785 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6786 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6787 scm_internal_catch to establish a catch-all handler, using
6788 scm_handle_by_message. This replaces the special-case code in
6790 (invoke_main_func): Body function for scm_internal_catch; invoke
6791 the user's main function, using the main_func_closure pointer to
6792 decide what to pass it.
6793 * root.c (struct cwdr_body_data): Remove handler_proc member.
6794 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6795 (cwdr_handler): Removed.
6797 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6799 * socket.h (SCM_P): update bind prototype.
6800 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6801 include "feature.h".
6802 (scm_socket): return a port, not a file descriptor object.
6803 include "fports.h" and <unistd.h>
6804 (scm_bind): take a port, not a file descriptor object.
6805 take an extra argument for address args.
6807 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6808 INADDR_NONE, INADDR_LOOPBACK.
6810 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6812 * init.c: include net_db.h and not fdsocket.h.
6813 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6815 * Makefile.am: corresponding changes.
6816 * socket.h: renamed from fdsocket.h, fix names.
6817 * net_db.h: renamed from socket.h, fix names.
6818 * socket.c: renamed from fdsocket.c.
6819 remove _sys from procedure names.
6820 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6821 add "socket" to features list.
6822 * net_db.c: renamed from socket.c.
6823 remove _sys from procedure names.
6824 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6825 add "net-db" to features list.
6826 include "net_db.h". don't include <sys/socket.h> or
6829 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6831 * tags.h (scm_tags): Removed comma at end of last enumerator.
6833 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6835 Don't use GCC extensions to allocate space for debugging frames.
6836 (Here he goes again! Why do we put up with this?!)
6837 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6838 an scm_debug_info structure, not an in-line array of them. Add
6839 'info' member, to say how many vect elements we've used, for eval
6841 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6842 a new variable debug_info_end to mark the end of vect, instead of
6843 the address of the 'info' pointer itself.
6844 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6845 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6846 (SCM_APPLY): Explicitly allocate space for debug.vect.
6847 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6848 * stacks.c: Adjusted for new debug frame structure.
6849 (RELOC_INFO, RELOC_FRAME): New macros.
6850 (stack_depth, read_frames): Use them, and new scm_debug_frame
6851 element 'info', instead of magically knowing that eval frames have
6852 an info pointer sitting after vect.
6853 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6855 (scm_init_stacks): Formatting tweaks.
6857 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6859 Give GCC more control flow information, so it can be sure that
6860 variables aren't used uninitialized.
6861 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6862 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6863 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6864 scm_misc_error): Tell GCC that these functions never return.
6865 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6866 out the field type, call abort if SCM_ASSERT returns, to placate
6868 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6869 scm_wta ever returns. We can't handle this case anyway, and this
6870 gives the optimizer more information.
6871 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6872 scm_wta ever returns.
6874 In some cases, the code is fine, but GCC isn't smart enough to
6875 figure that out; this usually happens when one variable is only
6876 initialized and used when a particular condition holds true, and
6877 we know that condition will never change within a given invocation
6878 of the function. In this case, we simply initialize the variables
6879 to placate the compiler, hopefully to a value which will cause a
6880 crash if it is ever actually used.
6881 * print.c (scm_iprin1): Initialize mw_pos.
6882 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6883 * throw.c (scm_ithrow): Initialize dynpair.
6884 * unif.c (scm_uniform_vector_ref): Initialize cra.
6885 * struct.c (init_struct): Initialize prot.
6886 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6888 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6889 if EXPR contains no expressions.
6891 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6893 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6894 cause an infinite loop (???). So much for the algebraic
6895 equivalency of variable-sized arrays and alloca...
6897 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6899 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6900 a SCM boolean, not a C boolean.
6902 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6904 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6905 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6906 rules for raising scm_mtrigger. Previously, unfortunate but not
6907 unlikely circumstances could result in almost constant invokation
6908 of the gc. Now, this situations should be less likely, but they
6909 are not prevented completely.
6911 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6913 * numbers.c (scm_fuck): Procedure removed; looks like old test
6915 * numbers.h: Prototype removed.
6917 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6919 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6920 array to a pointer, to match my Nov 21 change in eval.c.
6922 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6924 * libguile.h: Added #include "libguile/backtrace.h", #include
6925 "libguile/stacks.h".
6927 * strings.c (scm_string scm_make_string scm_string_ref
6928 scm_string_set_x scm_string_equal_p scm_string_append):
6929 Bugfix according to scm patch from Aubrey Jaffer:
6930 Corrected long-standing
6931 (not (eqv? (integer->char 128)
6932 (string-ref (make-string 1 (integer->char 128)) 0)))
6933 bug found by John Kozak <jk@noontide.demon.co.uk>.
6935 * strports.c, strports.h: Make scm_eval_0str return the value of
6936 the last expression evaluated (previously, it returned void).
6938 * strports.c, strports.h: New function: scm_read_0str. Does what
6941 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6943 * simpos.c (scm_getenv): return #f if string can't be found in the
6944 environment instead of throwing an exception, for compatibility
6945 with numerous other systems.
6947 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6949 * Makefile.am (.c.x): Use guile-snarf.
6950 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6952 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6954 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6956 * backtrace.c (scm_display_error_message): Made non-static, and
6957 renamed from display_error_message.
6958 * backtrace.h (scm_display_error_message): Added extern decl.
6959 * throw.c (uncaught_throw): Use it to display the error message.
6961 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6963 * inet_aton.c: Use #if 0, not #ifdef 0.
6965 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6967 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6968 to convert the returned value.
6969 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6970 the offset argument.
6972 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6974 Add new interface to catch/throw, usable from C as well as
6976 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6977 (scm_internal_catch): New function, replaces...
6978 (scm_catch_apply): Deleted.
6979 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6980 mechanism which is a bit more code, but can be used nicely from C
6981 and implement the Scheme semantics as well.
6982 (scm_internal_catch): This is the replacement; it's named after
6983 the analogous function in Emacs.
6984 (scm_catch): Reimplemented in terms of the above.
6985 (struct catch_body_data, catch_body, catch_handler): New
6986 functions, used by scm_catch.
6987 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6988 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6989 support for new cwdr.
6991 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6994 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6996 * acconfig.h: Added DYNAMIC_LINKING symbol.
6997 * configure.in: Add option and checks for dynamic linking.
6998 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6999 dynl.h: New files for dynamic linking support.
7000 * Makefile.am (libguile_a_SOURCES):
7002 (modinclude_HEADERS): Added "dynl.h".
7003 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
7005 * init.c (scm_boot_guile_1): Call
7006 scm_init_dynamic_linking to initialize dynamic linking support.
7008 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
7010 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
7011 (as we Schemers say). It needs to be global, so that I can tweak
7012 it for the proper operation of unexec.
7013 (scm_boot_guile_1_live): New variable, see above.
7015 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
7017 * guile-snarf.sh: Removed.
7018 * PLUGIN/guile.libs: Added dependency for -lm.
7019 * acinclude.m4: Renamed from aclocal.m4.
7020 * PLUGIN/greet: Removed.
7021 * Makefile.am, aclocal.m4: New files.
7022 * configure.in: Updated for Automake.
7024 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
7026 * eval.c (scm_definedp): Use top_level_lookup_closure_var
7027 and not top_level_lookup_thunk_var.
7029 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
7031 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
7033 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
7035 * eval.c (scm_definedp): Incompatibly changed to be a builtin
7036 Scheme function, instead of syntax. Single argument is now a
7039 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7041 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
7042 scm_ra_divide): Properly terminate statements passed as arguments
7043 to IVDEP macros. (Thanks to Bernard Urban.)
7045 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
7046 with non-constant sizes. (Thanks to Bernard Urban.)
7048 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7050 It's an "eval closure", not an "eval thunk." A thunk is a
7051 function of no arguments.
7052 * root.h (struct scm_root_state): Renamed
7053 top_level_lookup_closure_var from top_level_lookup_thunk_var.
7054 (scm_top_level_lookup_closure_var): Renamed from
7055 scm_top_level_lookup_thunk_var.
7056 * root.c (mark_root): Uses changed.
7057 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
7058 * init.c (scm_start_stack): Uses changed.
7059 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
7060 Change scheme-visible name to *top-level-lookup-closure* from
7061 *top-level-lookup-thunk*.
7063 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
7065 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
7066 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
7068 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
7070 * gc.c (struct scm_heap_seg_data): Doc fixes.
7072 * gc.c (scm_gc_sweep): Empty all segments' freelists before
7073 sweeping. Then, prepend each segment's free cells to its
7074 freelist, rather than wiping out the old value. (Thanks to Marius
7077 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
7078 scm_check_freelist, scm_debug_newcell): New functions and
7079 variables, for debugging freelist problems.
7080 * pairs.h (SCM_NEWCELL): New debugging version added.
7081 * gc.h (scm_debug_newcell): Added extern declaration, used by
7082 debugging version of SCM_NEWCELL.
7084 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7086 On some systems <libc.h> conflicts with <unistd.h>, and should not
7087 be #included at all.
7088 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
7089 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
7090 * configure.in: Call it.
7091 * posix.c, filesys.c: Use its results to decide whether or not to
7093 * configure, scmconfig.h.in: Rebuilt with autoconf and
7096 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7098 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
7099 pointer to the stdio stream before calling scm_setbuf0, so the
7100 latter will be able to retrieve it. I'm surprised this didn't
7101 segfault earlier. (Thanks to Christopher Lee.)
7103 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7105 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
7108 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7110 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
7111 number of stack narrowing specifier pairs. The first specifier in
7112 a pair controls inner border, the second the outer border. A
7113 number means cut that number of frames, a procedure object means
7114 cut until that object is found in operator position in a frame.
7116 * root.c (cwdr): Bugfix.
7118 * read.c: Recording of positions disabled by default.
7120 * procs.c (scm_closure_p): New function.
7122 * posix.c (scm_tmpnam): New function.
7124 * load.c: Added #include "throw.h".
7125 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
7128 * load.c, load.h (scm_read_and_eval_x): New function.
7130 * eval.c: Renamed debug option "deval" to "debug".
7132 (scm_eval_x): `eval!' is no longer accessible from the scheme
7133 level. Motivation: We can't allow operations which introduce
7134 glocs into the scheme level. Guile's type system can't handle
7135 these as data. Use `eval' or `read-and-eval!' as replacement.
7137 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
7138 SCM_CONSP since this is a macro!; Set vframe.prev to
7139 scm_last_debug_frame instead of 0. In this way we can look
7140 "above" the virtual start stack frame if we wish.
7141 (scm_debug_hang): New function: Useful for debugging Guile in
7142 certain tricky situations. Will probably be removed later...
7144 * debug.h: Changed semantics of debug option "backtrace". This
7145 option now only indicates whether we want automatic backtrace at
7148 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7150 * ports.c: #include "filesys.h"
7151 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
7153 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
7154 Motivation: This is system specific code which is related to file
7155 I/O. It also may use select. Added code by Gary Houston to
7156 detect presence of character in stdio buffers.
7158 * libguile.h: #include "libguile/libpath.h"
7160 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
7161 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
7162 SCM_SITE_DIR; Install libpath.h among the other include files.
7164 * load.c, load.h (scm_sys_package_data_dir): New function.
7166 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7168 * stacks.h: Bugfix: Don't use tail-array length field as stack
7169 length field! This screwed GC.
7171 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7173 * _scm.h: Added #ifndef around definition of macros min and max.
7175 * __scm.h: Added hooks for threads to plugin to in ints protection
7176 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
7177 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
7178 the main code in these macros duplicated and spread over multiple
7179 files. Renamed SCM_THREADS_SWITCHING_CODE ->
7180 SCM_THREAD_SWITCHING_CODE.
7182 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
7184 * snarf.h: New file.
7185 * guile-snarf.sh: New file.
7186 * Makefile.in (inner_h_files): Added snarf.h
7187 (ancillary, install, uninstall, distclean): Added actions for
7189 (.c.x): Use guile-snarf.
7190 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
7191 (gen_c_files): Note that these depend on guile-snarf.
7192 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
7193 now in "snarf.h". Added #include "snarf.h" to get them.
7194 * libguile.h: Added #include "snarf.h".
7195 (Patches applied and tweaked by Jim Blandy.)
7197 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7199 * socket.c: Use K&R style declaration for 'close'; the GNU coding
7200 standards suggest against providing prototypes for system
7201 functions. Thanks to Greg Troxel.
7203 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
7205 * strports.c (scm_eval_0str): New function.
7206 #include "read.h", to get prototype for scm_read.
7207 * Makefile.in (strports.o): Update dependencies.
7208 * strports.h: New prototype.
7210 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
7211 scheme name from "int?" to "integer?". It seems to do the job.
7212 * numbers.h: Rename prototype too.
7213 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
7216 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
7217 scm_num_eq_p): Rename these according to R4RS conventions: call
7218 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
7219 to making libguile R4RS compliant without ice-9...
7221 * load.c (scm_sys_search_load_path): Search for files under all
7222 extensions listed in the %load-extensions variable. If FILENAME
7223 is absolute, return it unchanged, without searching the load path.
7224 (scm_loc_load_extensions): New variable, pointing to
7225 %load-extensions' value cell.
7226 (scm_init_load): Initialize it, and the value it points to.
7227 (scm_primitive_load_path): Improve error reporting.
7229 * load.c (scm_loc_load_hook): New variable, pointing to value cell
7230 of new Scheme variable %load-hook.
7231 (scm_primitive_load): Apply %load-hook to filename.
7233 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
7235 * configure.in: add tests for figuring out whether buffered data
7236 is available in a FILE structure, which is needed by char-ready.
7238 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
7241 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
7242 exceptions using misc_error instead of syserror. It seems a bit
7243 odd to throw an exception if a string can't be found in the
7244 environment, but it's consistent with open-file, stat etc.
7245 (simpos.h): remove sys_ from getenv.
7247 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
7248 occurs, throw an error instead of returning errno. Return value
7250 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
7252 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
7254 * filesys.c (scm_stat2scm): derive file type and permissions from
7255 the stat mode and append them to the returned vector.
7256 There isn't much overhead in doing this and it avoids the need to
7257 work with S_IRUSR et al. in Scheme.
7258 Define symbols scm_sym_regular etc.
7259 (scm_init_filesys): don't intern S_IRUSR etc.
7261 * load.c: change s_try_load and s_try_load_path to s_primitive_load
7262 and s_primitive_load_path.
7264 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
7266 * error.h: don't declare error symbols. prototype for scm_misc_error.
7268 * stackchk.c (scm_stack_overflow_key): defined here instead of in
7271 * error.c: use SCM_SYMBOL to set up error keys.
7272 scm_misc_error: new procedure.
7274 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7276 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
7277 between `#!' and `!#' is ignored.
7278 (skip_scsh_block_comment): New function.
7280 * feature.c (scm_set_program_arguments): New argument, FIRST.
7281 * feature.h: Update prototype.
7282 * init.c (scm_boot_guile_1): Pass new argument to
7283 scm_set_program_arguments.
7285 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7287 * init.c (scm_start_stack): Don't initialize scm_progargs here.
7288 (scm_boot_guile): Call scm_set_program_arguments here, later than
7289 the old initialization.
7291 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
7292 initialization procedure.
7293 - Delete in, out, err arguments; there are other perfectly good
7294 ways to override these when desired.
7295 - Delete result argument; this function shouldn't ever return.
7296 - Rename init_func argument to main_func, for less confusion.
7297 - Delete boot_cmd argument; main_func is more general.
7298 -Add 'closure' argument, to help people pass data to main_func
7299 without resorting to global variables.
7300 - Abort if reentered; don't bother returning an error code.
7301 - Call scm_init_standard_ports to set up the default/current
7302 standard ports; no need to pass them to scm_start_stack.
7303 - Remove code to evaluate the boot_cmd, and start the repl; let
7304 the user do something like that in main_func if they want.
7305 - Remove code to package up a return value; main_func can do any
7307 - Call exit (0), instead of returning.
7308 (scm_start_stack): Don't initialize the I/O ports here; that's
7309 weird. Delete in, out, err arguments. Move guts to
7310 scm_init_standard_ports, scm_stdio_to_port.
7311 (scm_init_standard_ports): New function, to set up current and
7312 default standard ports.
7313 (scm_start_stack, scm_restart_stack): Make these static.
7314 * init.h (scm_boot_guile): Adjust declaration.
7315 (scm_start_stack, scm_restart_stack): Remove externally
7316 visible declarations for these.
7317 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
7319 * fports.c (scm_stdio_to_port): New function. Its guts used to be
7320 written out several times in scm_start_stack.
7321 * fports.h: New declaration for the above.
7323 * feature.c (scm_set_program_arguments): New function.
7324 * feature.h: New declaration for the above.
7326 * ports.c: Formatting tweak.
7328 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
7330 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
7331 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
7332 for obtaining the address of a car or cdr field. Motivation:
7333 &SCM_CXR make assumptions about the internal structure of the
7336 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
7337 Motivation: see SCM_CXRLOC.
7339 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
7340 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
7341 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
7342 Motivation: Safer use. Some other macros are defined in terms of
7343 these operations. If these are defined using the SCM_SETCXR
7344 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
7345 to inefficiency and an <e1> with side-effects could potentially
7346 break. Also, these particular operations are heavily utilized in
7347 the garbage collector. In unoptimized code there will be a
7350 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
7351 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
7352 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
7353 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
7354 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
7355 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
7356 vports.c: Cleaned up use of pairs: Don't make any special
7357 assumptions about the internal structure of selectors and
7358 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
7359 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
7360 (Among other things, this change makes it easier to build Guile
7361 with certain compilers which have problems with casted lvalues.)
7363 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7365 * stacks.c: Improve selection of relevant stack frames when making
7366 a stack object. Introduce one level of indirection in the stack
7367 object to make it possible to "narrow" to a certain region of the
7368 stack. This facilitates making use of more clever algorithms (not
7369 implemented) for selecting relevant frames and gives a cleaner
7370 design since selection of frames can be done independently of
7371 extraction of frames from the real stack.
7372 (scm_stack_id): Also take #t as argument which means look at
7375 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
7376 Turn n_tail into an integer directly representing current number
7377 of frames in stack. Add field tail.
7379 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
7381 * debug.c (scm_make_memoized): Made it available at scheme level.
7382 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
7383 SCM_NIMP before applying heavier predicates in argument checking.
7384 (scm_local_eval): Also take memoized object as argument.
7386 * backtrace.c (scm_display_error): Just a safety measure: Stacks
7387 aren't created with zero length, but should such a strange
7388 creature suddenly turn up...
7390 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
7392 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
7393 `del', for the sake of C++ compilers. (Patch applied by JimB.)
7395 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
7397 * variable.c (scm_make_variable): Make the name hint optional, as
7399 (anonymous_variable_sym): Renamed from variable_sym. All uses
7402 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7403 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7404 of scm_primitive_load_path was also changed to
7405 "primitive-load-path", from "%try-load-path". Callers changed.
7406 We'd like to respect the convention that a function named
7407 "try-mumble" should behave just like the function called "mumble",
7408 but return #f instead of signalling some error.
7409 * load.h: Rename prototypes.
7411 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7413 * print.c (make_print_state, grow_print_state), print.h: Modified
7414 the print state representation: Don't use a tail array for
7415 recording of circular references. Resizing of the print state
7416 structure invalidates the print state pointer. To avoid passing
7417 around an indirect print state reference to all printing
7418 functions, we instead let the print state reference a resizable
7421 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7423 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7424 Don't crash when passed an improper list terminated by a
7425 non-immediate value.
7427 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7429 Allocate data for structures on an eight-byte boundary, as
7430 required by the tagging system.
7431 * struct.c (alloc_struct): New function.
7432 (scm_make_struct, scm_make_vtable_vtable): Call it.
7433 * struct.h (scm_struct_n_extra_words): Bump to 3.
7434 (scm_struct_i_ptr): New "field".
7435 * gc.c (scm_gc_sweep): When we need to free the data, use the
7436 information stored by alloc_struct to find the beginning of the
7437 block allocated to the structure, so we can free it.
7439 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7441 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7444 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7445 (scm_debug_info): New member: id.
7447 * stacks.c: Stacks are now represented as structs; Stacks have an
7448 id given to them by `start-stack'.
7449 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7451 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7452 Changed stack representation.
7454 * debug.c (scm_procedure_name): Try procedure property `name' for
7455 compiled closures aswell.
7457 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7459 * eval.c: scm_i_name moved to gsubr.c
7460 (scm_m_define): Record names of all kinds of procedure
7461 objects. (Earlier, only closures were recorded.)
7463 * procprop.h: Added declaration of scm_i_name.
7465 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7466 (scm_make_gsubr): Record names of compiled closures.
7468 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7470 * debug.c, debug.h: Removed obsolete code.
7472 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7473 stacks.c: Renamed regs --> scm_contregs.
7475 * print.c (scm_free_print_state): Cleanup print state before
7476 returning it to pool. It is better to do it here than in
7477 scm_prin1 since scm_prin1 is called often.
7479 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7480 s_set_source_property_x): Check that first argument is a pair or a
7483 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7484 scm_i_line, scm_i_column and scm_i_breakpoint global.
7486 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7487 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7490 * debug.h: Added debug object smob declaration and macro
7493 * configure.in: Build with backtrace.o and stacks.o if debug
7496 * Makefile.in: Added entries for new files: backtrace.c,
7497 backtrace.h, stacks.c and stacks.h.
7499 * symbols.c (scm_sym2ovcell): Fixed documentation.
7501 * _scm.h (min, max): Added.
7503 * async.c: Moved `min' macro to _scm.h.
7505 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7506 SCM_BACKTRACE_INDENT.
7508 * eval.c: Added new debug options `maxdepth' and `indent'.
7510 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7512 * print.h: Added selector SCM_PRINT_STATE.
7514 * print.c: New functions: scm_make_print_state,
7515 scm_free_print_state.
7517 * print.h: Added declarations for scm_make_print_state,
7518 scm_free_print_state.
7520 * debug.c (scm_m_start_stack): New acro.
7522 * debug.h: Small cleanup.
7524 * init.c (scm_boot_guile_1): Moved scm_init_debug below
7527 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

7547 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
7548 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
7549 declare functions with prototypes. (Patch thanks to Marius
7552 More prototype-related changes from Marius Vollmer:
7553 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7554 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7555 * ports.h (ptobfuns): Added prototypes. This means some casting in
7557 * fports.c: Added casts for initializations, since the functions
7558 are defined to take FILE * as their stream argument, not SCM.
7559 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7560 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7561 to `char *str_data' to conform to prototype.
7563 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7565 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7567 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7569 * stime.c, stime.h: use SCM_P method.
7571 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7573 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7574 be given at least two arguments. Insist that lst's last element
7575 be a list, but don't make any requirements of its predecessors.
7577 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7579 * eval.c (scm_nconc2last): Revert last change; there seems to be
7580 other stuff going on here.
7582 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7584 * eval.c (scm_nconc2last): Make sure that each element of lst
7585 (which is a list of argument lists, except for the tail) is a
7586 proper list, i.e., finite and terminated by '().
7588 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7590 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7593 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7594 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7597 * vectors.c (scm_make_vector): Fill vectors with the undefined
7598 value, to help make Guile Scheme code more portable to other
7601 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7602 * symbols.h, tags.h: Doc fixes.
7604 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7606 * async.c (scm_take_signal): Doc fixes.
7608 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7610 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7611 want to subtract it from the modulus; we just want to leave it
7614 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7616 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7619 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7621 * throw.c (scm_catch_apply): Finished implementation of
7624 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7626 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7628 (scm_init_filesys): set "i/o-extensions" feature.
7631 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7633 * Makefile.in (root.o): Correct dependencies.
7635 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7637 * Makefile.in: Added dependency entry for root.o.
7639 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7640 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7642 * init.c (scm_start_stack): Set initial root continuation number
7645 * procs.c: New function: scm_thunk_p.
7647 * procs.h: Added declarations of scm_thunk_p.
7649 * root.c: Renamed `call-with-new-root' -->
7650 `call-with-dynamic-root'.
7651 (cwdr): Removed allocation of new root state. This should be done
7652 separately by use of scm_make_root.
7653 (scm_apply_with_dynamic_root): New function: Does what it
7654 sounds like. Needed when spawning threads.
7656 * root.h: Added member last_debug_frame to root state.
7657 Added #include "libguile/debug.h"
7659 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7660 arguments. The motivation is that code in root.c needs catch
7661 functionality, and we want to avoid code duplication.
7662 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7663 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7664 handlers that run without popping the stack into the dynwind
7667 * throw.h: Added prototypes for scm_catch_apply and
7670 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7672 * root.h (scm_root, scm_set_root): Decouple thread support details
7673 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7674 SCM_SET_THREAD_LOCAL_DATA.
7676 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7677 and tortoise scanning loop.
7679 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7681 * Makefile.in: Rebuild dependencies.
7683 * libguile.h: #include "libguile/print.h" before "smob.h", since
7684 the latter uses the print_state structure.
7686 * throw.c (scm_ithrow): Use the correct variable when checking to
7687 see if a given element of scm_dynwinds is a valid catch.
7689 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7690 structure, abort; don't just silently ignore the garbage.
7692 * _scm.h: #include "print.h" here, since it seems to be used just
7694 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7695 strports.c, unif.h: Don't #include "print.h".
7697 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7699 * feature.h (scm_loc_features): Removed external declaration.
7700 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7702 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7704 * feature.c (scm_init_feature): Added threads feature (needs to be
7705 initialized here, since features doesn't exist when
7706 scm_init_threads is called).
7708 * libguile.h: Added #include "libguile/../threads/threads.h".
7709 (This is a kludge to get thread support working. This should be
7712 * configure.in, acconfig.h: Added flags for thread support.
7714 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7717 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7718 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7721 * _scm.h: Added conditional #include "threads.h"
7723 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7724 SCM_THREADS_SWITCHING_CODE.
7726 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7727 allocate the basic dynamic root object.
7728 (scm_boot_guile): Added call to scm_init_root.
7730 * root.c, root.h: Added root smob.
7731 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7732 functions: Implements dynamic roots mostly according to spec in
7733 SCM manual. Main difference is that the second argument is a
7734 throw handler rather than an error "thunk".
7736 * root.h: Added declaration of scm_init_root.
7738 * root.c: Added #include "genio.h", #include "smob.h", #include
7739 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7741 (scm_init_root): Added #include "root.x".
7743 * throw.c: Added #include "stackchk.h"
7744 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7745 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7746 can be used in scm_call_with_new_root; Added reenabling of stack
7747 checking when catching a throw.
7749 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7751 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7753 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7754 element is not found, as per R4RS.
7756 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7758 * list.c: Doc fixes throughout.
7760 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7762 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7763 declare the char * to be const. Avoids a warning in rgx.c.
7765 * ports.h: spelling fix.
7767 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7770 * load.c (scm_sys_try_load_path): throw an error if file not found
7771 (like it says it in NEWS).
7773 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7775 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7776 PROPS slot to '(), not #f; it's an empty alist.
7778 * throw.h, throw.c: Use SCM_P instead of #if hair.
7780 Remove special support for uncaught throws; see throw.c for
7782 * throw.c (uncaught_throw): New function.
7783 (scm_ithrow): Call uncaught_throw if we don't find a throw
7784 target; don't mess with scm_bad_throw_vcell.
7785 (scm_bad_throw_vcell): Variable deleted.
7786 (scm_init_throw): Don't initialize it.
7788 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7791 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7793 * numbers.c (scm_istr2int): If the number is short (as most
7794 numbers are), just call scm_small_istr2int to deal with it.
7795 (scm_small_istr2int): New function, created by un-#ifdefing the
7796 non-bignum version of scm_istr2int and renaming it.
7798 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7800 * load.c (scm_sys_try_load): don't check whether value returned
7801 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7802 Change the Scheme name from %try-load to primitive-load.
7804 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7805 Can avoid passing a message, allowing it to be derived in the
7806 error handler (e.g., if we want to throw to the key both from
7809 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7811 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7812 references now have a new appearance which is more compact and
7813 also gives a clue about what the target of the reference is.
7814 By setting parameters in the print state, more fancy printing can
7815 be achieved. This is used by the (not yet commited) backtrace
7818 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7820 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7823 * print.c: Added #include "struct.h". Removed function
7826 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7827 scm_iprin1. Removed prototype for scm_prlist.
7829 * arbiters.c (prinarb),
7830 async.c (print_async),
7831 debug.c (prindebugobj, prinmemoized),
7832 eval.c (prinprom, prinmacro),
7833 filesys.c (scm_fd_print, scm_dir_print),
7835 mallocs.c (prinmalloc),
7836 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7837 smob.h (scm_smobfuns),
7838 srcprop.c (prinsrcprops),
7840 unif.c, unif.h (scm_raprin1, rapr1),
7841 variable.c (prin_var): Changed argument `int writing' to
7842 `scm_print_state *pstate'.
7844 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7845 that it will be called before scm_init_print.
7847 * print.c (scm_prin1): Print states are now allocated when calling
7848 scm_prin1 and then passed around to all printing functions as an
7849 argument. A cache `print_state_pool' enables reuse of print
7851 (scm_make_print_state): New function.
7852 (scm_iprin1): Adaption to print states.
7853 (scm_iprlist): An initial "hare and tortoise" scan brings down
7854 time complexity to O (depth * N). (Better time complexity will be
7855 achieved when the printing code is completely rewritten.)
7857 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7859 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7860 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7861 it gets done whether or not the cache variable has a value.
7863 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7865 Distinguish #f and ().
7866 * __scm.h: #undef SICP.
7867 * pairs.h (SCM_EOL): Delete this definition, equating it with
7869 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7870 the value it used to have. Doc fixes, too.
7872 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7874 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7875 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7876 Lord's implementation of structs, allowing for tail arrays as
7877 described in the manual. Also fixed some bugs. (Both the interface
7878 and the implementation should be improved.)
7880 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7882 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7883 People who whish to see the source can do `(print-enable 'source)'.
7884 Removed #ifdef DEBUG_EXTENSIONS.
7886 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7888 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7889 integer (assuming for now accepting an integer is a good thing).
7891 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7892 %S will be used instead for write'ing arguments.
7894 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7895 asserts. fix a few other asserts.
7896 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7897 scm_uniform_vector_ref, scm_array_set_x,
7898 scm_dimensions_to_unform_array): change args in
7899 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7900 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7901 scm_substring_fill_x): likewise.
7902 gsubr.c (scm_gsubr_apply): likewise.
7903 eval.c (SCM_APPLY): likewise.
7905 * eval.c (4 places): replace scm_everr with lgh_error or
7908 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7909 scm_memory_error): new procedures.
7910 scm_everr: deleted. can use scm_wta, dropping first two args.
7911 scm_error: convert NULL subr to SCM_BOOL_F.
7913 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7916 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7919 * error.c, error.h: new error keys: scm_arg_type_key,
7920 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7922 scm_wta: reimplement using lgh_error instead of scm_everr.
7924 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7926 * gdbint.c: scm_lread now has one more argument.
7928 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7929 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7930 loading source from non-file ports, which, e. g., happens when
7931 using the Emacs interface).
7933 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7936 * read.c: Added code for recording of positions of source code
7937 expressions; New functions: recsexpr, scm_lreadrecparen;
7938 _scm_make_srcprops --> scm_make_srcprops
7939 (scm_flush_ws): Removed updating of positions counters. This work
7940 is already done by scm_gen_getc
7942 * read.h: Added prototype for scm_lreadrecparen
7944 * print.c: Added #include "alist.h"
7946 * eval.c: Added #include "hash.h"
7948 * eq.c: Added #include "ramap.h"
7950 * options.c: Documentation fixes.
7952 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7953 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7954 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7955 --> scm_make_srcprops
7957 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7958 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7959 function calls in the definition of the whash access macros.
7961 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7963 * init.c (scm_boot_guile): Add level of indirection to
7964 scm_boot_guile_1() to ensure that stack base pointer is properly
7965 initialized. There was no guarantee that variable i was the
7966 highest/lowest variable on stack (i.e. the call frame of
7967 scm_boot_guile was not completely protected from gc).
7969 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7971 * ports.h (scm_port_table): put back file_name, it will be used to
7972 support debugging. Undo related changes in fports.c, ioext.c,
7975 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7977 * ports.h (scm_port_table): remove file_name member for now, it seems
7979 * fports.c (scm_open_file): don't set file_name in PTAB.
7980 (prinfport): don't use file_name in PTAB.
7981 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7982 * ports.c (scm_add_to_port_table): don't intialize file_name.
7983 (scm_port_file_name): remove for now.
7984 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7986 * fports.h (scm_mkfile): prototype deleted.
7987 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7989 * debug.c, unif.c: use scm_out_of_range instead of
7990 wta for range errors (ASSERT still needs work).
7992 * error.c, error.h (scm_out_of_range): new procedure.
7994 * error.c, error.h (scm_out_of_range_key): new key.
7996 * posix.c (scm_sync): #else was missing.
7998 * error.c, error.h: append _key to names scm_num_overflow and
8001 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
8002 of consing an empty list.
8003 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
8004 of macros, saves code and string space.
8005 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
8006 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
8007 lower case. Rename scm_syserror_m to scm_syserror_msg.
8008 error.h: prototypes for new procedures.
8010 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
8012 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
8014 * error.c, error.h: setup scm_num_overflow key.
8016 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
8017 Remove definition of SCM_OVSCM_FLOW.
8019 * fports.c (scm_open_file): use SCM_SYSERROR_M.
8021 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
8022 explicit message and args.
8024 * error.c, error.h, __scm.h: change system_error_sym to
8027 * error.c (system_error_sym): remove leading %% from the Scheme name
8030 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
8032 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8034 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
8035 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
8036 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
8037 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
8038 renamed. (These were introduced by unsupervised name
8041 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8043 * print.c: Added code for detection of circular references during
8044 printing. (init_ref_stack, grow_ref_stack): New functions. Added
8045 a hook for printing of closures (accessible via print options).
8046 This leads to a split of calls to scm_iprin1 into two classes:
8047 elementary print operations (e. g. the code which prints a smob)
8048 still use scm_iprin1 while top level calls (like scm_display) use
8049 scm_prin1. scm_prin1 begins by clearing the data structure used
8050 to record reference information.
8052 * print.h: Added declarations of scm_prin1 and scm_prlist.
8054 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
8056 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
8058 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
8060 * error.c (err_head): scm_iprin1 --> scm_prin1
8062 * debug.c: Adjusted header comment.
8066 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
8068 * strerror.c: Doc fix.
8070 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8072 * gdbint.c (gdb_read): Now possible to run during GC.
8073 (unmark_port, remark_port): New functions.
8075 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
8077 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
8078 of allocating a new string object. Also, increase size by
8079 the factor 2 instead of 1.5.
8081 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
8083 * __scm.h (SCM_P): Corrected to run under traditional C.
8085 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
8088 * async.c: Calls to scm_sysintern corrected.
8090 * async.h (scm_async_clock): Redundant declaration removed.
8092 * continuations.c (scm_dynthrow): Redundant declaration removed.
8094 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
8095 Definition typos corrected.
8097 * debug.h: Missing declarations of functions in debug.c added
8100 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
8101 Missing declarations to functions in eval.c added.
8103 * filesys.c: Possibly uninitialized variable rv.
8105 * gc.h (scm_object_addr, scm_unhash_name): Missing
8106 declarations of functions defined in gc.c added.
8108 * genio.c: Possible typos str_data -> wstr_data. ???
8110 * genio.c: Possibly unintended shadowing of local variable
8111 `int c' (gotos out of scope of inner `c'). ???
8113 * init.c: Uninitialized `SCM last' may be used.
8115 * ioext.h: (scm_sys_isatty_p): Typo.
8117 * list.h (scm_list_head): Missing prototype for function in
8120 * numbers.c (scm_two_doubles): Changed from extern to static
8121 (is used only within numbers.c).
8123 * numbers.h: Repeated declarations removed.
8125 * ports.h (scm_close_all_ports_except): Declaration for the
8126 function defined in ports.c added.
8128 * posix.h: Missing declarations added.
8130 * procs.h (scm_make_subr_opt): Missing declaration added.
8132 * socket.h (scm_sys_gethost): Missing declaration added.
8134 * socket.h: Redundant declarations removed (they are in fdsocket.h).
8136 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
8137 Missing declarations added.
8139 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
8141 * struct.c: Uninitialized variable `SCM answer' may be used.
8143 * unif.c (l2ra): Declaration prototype.
8145 * unif.c (scm_array_equal_p): Dummy definition removed (it is
8146 defined in ramap.c).
8148 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
8149 Redundant declarations removed (they are in ramap.h).
8151 * variable.h (scm_make_udvariable,
8152 scm_make_undefined_variable): Declaration corrected to
8153 correspond variable.c.
8155 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
8156 Missing declarations added.
8158 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
8160 * Makefile.in (distclean): Don't forget to delete fd.h.
8162 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
8164 * fd.h.in, tags.h: Trivial cleanups.
8166 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
8167 marksweep.h just declared functions from gc.c.
8168 * gc.h, libguile.h: Don't #include "marksweep.h".
8169 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8170 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
8171 dependencies updated.
8173 * libguile.h: Don't #include "files.h"; it's been deleted.
8175 * files.c (scm_sys_delete_file): Moved to filesys.c.
8176 File is now empty; deleted.
8178 * filesys.c: scm_sys_delete_file is now here. Remove
8179 #if's; they seem to rely on remnants of an old portability
8180 regimen. If the problems come up again, solve them properly,
8181 using autoconf. Specifically: Don't test M_SYSV, and #define
8182 remove to be unlink if it's #defined; don't use remove just
8183 because HAVE_STDC_HEADERS is #defined.
8184 * filesys.h: Add declarations for scm_sys_delete_file.
8185 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8186 files.o, files.h, files.c, and files.x.
8187 * init.c: Don't #include "files.h", and don't call scm_init_files.
8189 Use SCM_P instead of PROTO; the latter intrudes on the user's
8191 * params.h: Deleted; definition of SCM_P moved to...
8192 * __scm.h: ... here, where it replaces PROTO macro.
8193 * libguile.h, smob.h: Don't #include "params.h".
8194 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
8195 smob.h: Fix prototypes accordingly.
8196 * Makefile.in: Update dependencies.
8197 (inner_h_files): Remove params.h.
8199 * gc.c: #include "gc.h"; every module should include its header,
8200 to let the compiler cross-check the declarations against the
8203 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
8204 simpos.h: #include "libguile/__scm.h".
8206 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
8208 * init.c: Don't forget to #include smob.h and init.h.
8209 * Makefile.in: Dependencies updated.
8211 * smob.h: Use PROTO instead of #if __STDC__.
8213 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
8215 * __scm.h: Doc fixes.
8217 * __scm.h, libguile.h: Use "quotes" in the #includes, not
8218 <angles>; this allows `make depends' to work properly.
8220 * libguile.h: #include smob.h and pairs.h before the others; they
8221 define typedefs used by other headers.
8223 C files should #include only the header files they need, not
8224 libguile.h (which #includes all the header files); the pointless
8225 recompilation was wasting my time.
8226 * Makefile.in (all .o dependency lists): Regenerated.
8227 * libguile.h: Don't try to get a definition for size_t here...
8228 * __scm.h: Do it here.
8229 * _scm.h: Since this is the internal libguile header, put things
8230 here that all (or a majority) of the libguile files will want.
8231 Don't #include <libguile.h> here; that generates dependencies on
8232 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
8233 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
8234 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

8331 * weaks.c: Get "weaks.h".
8333 * stackchk.h: #include "libguile/debug.h",
8335 * print.h, read.h: #include "options.h", since everyone who uses
8336 either of these files will need that.
8338 * smob.h: #include "ports.h", "genio.h", and "print.h", since
8339 anyone who uses this file will need them to define the smob
8340 printing functions. Also, get markers.h, since people will need
8341 to #define the mark functions.
8343 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
8344 * ports.h: ... to here.
8346 * ports.h (scm_port_table_size): Explicitly give type as 'int';
8347 don't rely on archaic C default type rules.
8349 * fports.h: #include "libguile/ports.h", since you need that in
8350 order to parse this.
8352 * genio.h: #include "libguile/print.h", because you need that to
8353 parse this; don't bother #including "ports.h", since print.h gets
8356 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
8358 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
8359 this; it's now a reference to an element of *scm_root.
8361 * debug.h: Don't #include "options.h"; the compiler won't be able
8362 to find that once the headers are installed; instead, #include
8363 "libguile/options.h".
8364 * gc.h: Same, with marksweep.h.
8365 * mbstrings.h: Same, with symbols.h.
8366 * scmhob.h: Same, with _scm.h.
8367 * smob.h: Same, with params.h.
8369 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
8370 C files; there's no need for this, and it forces recompilations
8373 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
8375 * error.c (scm_error): declare scm_error_callback.
8377 * error.h: prototype for scm_error_callback.
8379 * __scm.h: define lgh_error.
8380 (SCM_SYSERROR): redefine using lgh_error.
8382 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
8384 * error.c (scm_error): new procedure.
8386 * error.h: prototype for scm_error.
8388 * Makefile.in (install): install scmconfig.h from the current
8389 directory, not $(srcdir).
8391 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8393 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8394 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8395 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
8396 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
8397 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
8398 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8399 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8400 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8401 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8402 vports.h, weaks.h: #include "libguile/__scm.h", not
8403 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
8404 dependencies are within libguile properly.
8406 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8408 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8409 when scmconfig.h doesn't exist.
8411 * load.c (scm_sys_try_load): Correct spelling.
8413 * feature.c (scm_loc_features): Make this static.
8415 * Makefile.in (libpath.h): Omit trailing slash from path. We
8416 shouldn't require it of users, so why put it here?
8418 Move code to initialize and search %load-path from ice-9 to C
8419 code, so we can use the load-path to find the ice-9 boot code;
8420 this makes it easier to run Guile without installing it. See
8421 corresponding changes in guile/Makefile.in.
8422 * feature.c: Move stuff concerned with the load path to load.c.
8423 (scm_compiled_library_path): Deleted.
8424 Don't #include libpath.h here.
8425 * feature.h: Don't mention scm_compiled_library_path.
8426 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8427 <sys/stat.h>, and <unistd.h> (if present).
8428 (R_OK): #define if the system hasn't deigned to.
8429 (scm_loc_load_path): New variable.
8430 (scm_init_load_path, scm_sys_search_load_path,
8431 scm_sys_try_load_path): New functions.
8432 (scm_init_load): Initialize scm_loc_load_path to point to the
8433 value cell of the Scheme %load-path variable.
8434 * load.h: Add declarations for scm_sys_search_load_path,
8435 scm_sys_try_load_path.
8436 * init.c: Call scm_init_load_path.
8437 * Makefile.in (feature.o, load.o): Dependencies updated.
8439 * load.c, load.h: Rewrite using PROTO macro.
8441 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8443 * gc.c (scm_cellp): New function: C predicate to determine if an
8444 SCM value can be regarded as a pointer to a cell on the heap.
8446 * gc.h: Added declaration of scm_cellp.
8448 * gdb_interface.h: New file: The GDB interface header from the GDB
8451 * gdbint.c: New file: GDB interface.
8453 * gdbint.h: New file: GDB interface.
8455 * libguile.h: Added #include <libguile/gdbint.h>.
8457 * init.c (scm_boot_guile): Added scm_init_gdbint.
8459 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8460 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8461 found if object files and source are kept separate).
8463 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8465 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8467 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8469 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8470 TK_SRC_DIR; they're not relevant any more.
8472 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8473 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8475 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8477 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8478 search path, so we can find the <libguile/MUMBLE.h> headers.
8480 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8482 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8483 implicit in the .c.o rule.
8484 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8487 Put the library path in a header file, instead of passing it on
8488 the command line in every compilation.
8489 * Makefile.in (libpath.h): New target.
8490 (feature.o): Depend on libpath.h.
8491 (clean): Delete libpath.h.
8492 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8493 * feature.c: ... #include "libpath.h" here.
8494 * .cvsignore: Ignore libpath.h.
8496 Don't install the unwashed masses of Guile header files in the
8497 main #include path; put most of them in a subdirectory called
8498 'libguile'. This avoids naming conflicts between Guile header
8499 files and system header files (of which there were a few).
8500 * Makefile.in (pkgincludedir): Deleted.
8501 (innerincludedir): New variable; this and $(includedir) are enough.
8502 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8503 (installed_h_files): Divide this up. Now this variable lists
8504 those header files which should go into $(includedir) (i.e. appear
8505 directly in the #include path), and ...
8506 (inner_h_files): ... this new variable says which files appear in
8507 a subdirectory, and are referred to as <libguile/mumble.h>.
8508 (h_files): List them both.
8509 (install): Create innerincludedir, not pkgincludedir. Put
8510 the installed_h_files and inner_h_files in their proper places.
8511 (uninstall): Corresponding changes.
8512 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8513 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8514 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8515 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8516 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8517 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8518 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8519 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8520 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8521 vports.h, weaks.h: Find __scm.h in its new location.
8522 * __scm.h: Find scmconfig.h and tags.h in their new locations
8523 (they're both "inner" files).
8525 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8527 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8529 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8531 * posix.c: Doc fixes.
8533 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8535 * socket.c: Don't include a prototype for inet_aton; just use a
8536 K&R style declaration, to avoid warnings but minimize the chance
8537 of conflicts with the system.
8539 On NextStep, <utime.h> doesn't define struct utime, unless we
8540 #define _POSIX_SOURCE before #including it.
8541 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8542 * acconfig.h: New comment text for above CPP symbol.
8543 * configure.in: Call it.
8544 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8546 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8548 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8549 testing for __EMX__.
8551 * posix.c: #include <libc.h>, if it exists.
8553 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8554 don't even know if the latter exists.
8556 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8557 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8558 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8560 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8562 (scm_init_posix): Use them when initializing the Scheme constants
8565 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8567 * Makefile.in (libdir, includedir, bindir): Use the
8568 autoconf-supplied values, instead of deriving them ourselves.
8569 (pkgincludedir, datadir, pkgdatadir): New variables.
8570 (install, uninstall): Put the header files in a special
8571 subdirectory, not in the main search path.
8573 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8574 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8576 * Makefile.in (IMPLPATH): Deleted; never used.
8578 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8579 on the Tcl/Tk source any more.
8580 (INCLUDE_CFLAGS): Remove references to the above.
8582 * Makefile.in (version.o): Corrected dependencies.
8584 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8586 * libguile.h: #include "version.h"
8588 * init.c (scm_boot_guile): Call scm_init_version.
8589 * gscm.c (gscm_run_scm): Call scm_init_version.
8591 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8592 GUILE_VERSION): AC_DEFINE these.
8593 (acconfig.h): #undef the above symbols.
8595 * Makefile.in (libobjs): Add version.o.
8596 (installed_h_files): Add version.h.
8597 (c_files): Add version.c.
8598 (gen_c_files): Add version.x.
8599 (version.o): New rule.
8600 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8601 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

8610 weaks.o): Add version.h to dependency lists.
8611 (markers.o): Remove duplicate rule.
8613 * version.h: New file.
8615 * version.c: New file.
8617 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8619 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8620 array; use it appropriately. Since GCC is quite happy to
8621 subscript functions, it never warned us about this; we should use
8622 -Wpointer-arith in the future. I guess we never tested
8625 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8627 * socket.c: Doc and copyright fixes.
8629 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8631 * debug.c: Fixed and improved gdb support.
8633 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8635 * socket.c: Added declaration of inet_aton to avoid compiler
8636 warning. (Hope this solution is correct.)
8638 * stime.c: Added declaration of ftime. (This is missing in
8641 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8643 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8645 * Makefile.in (c_files): add strerror.c.
8647 * strerror.c: new file from Emacs' sysdep.c.
8648 maybe configure should also check for sys_errlist.
8650 * configure.in (AC_REPLACE_FUNCS): add strerror.
8652 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8654 * debug.c (scm_init_debug): Added initialization for
8655 scm_evaluator_traps.
8657 * debug.h, debug.c: Various name changes.
8658 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8659 "debug-options-interface". See commentary in options.c.
8661 * options.h, options.c: Options now have documentation strings.
8662 Also added a long explanatory commentary.
8664 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8667 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8668 last_debug_info_frame is now updated in all cases.
8670 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8673 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8675 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8676 Added option STACK_CHECKING.
8678 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8680 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8682 * __scm.h: Removed symbols for debugging support.
8684 * acconfig.h: Added symbols for debugging support.
8686 * configure.in: Added user option for debugging support.
8687 --enable-debug will include the debugging code into libguile.a.
8689 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8690 scm_relocate_chunk_to_heap.
8692 * debug.c: New file: low-level debugging support. It also
8693 includes support for debugging with gdb. (The extensions to gdb
8694 are written by Per Bothner at Cygnus.)
8696 * debug.h: New file: low-level debugging support.
8698 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8699 argument pairs. Extensive modifications to the debugging
8700 evaluator. Added "SECTION:" commentaries to clarify what happens
8701 when, during double compilation. Renamed EVALIMP --> EVALIM.
8702 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8703 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8704 the beginning of the file. New procedure: scm_unmemocopy.
8705 Added some global state variables needed by the debugging
8706 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8707 check_entry, check_apply, check_exit, debug_options and
8708 evaluator_traps. New acro: undefine.
8710 * eval.h: Renamed EVAL --> XEVAL.
8712 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8713 --> scm_make_weak_key_hash_table.
8715 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8716 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8718 * libguile.h: Conditionally include debug.h
8720 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8721 scm_object_properties shouldn't return handle. `handle' now gets
8722 initialized in scm_set_object_properties_x. scm_object_properties
8723 doesn't any longer create an entry in scm_object_whash.
8725 * options.c: New file: handling of run time options.
8727 * options.h: New file: handling of run time options.
8729 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
8731 * print.c: New procedure: scm_print_options
8733 * print.h: Defines for print options.
8735 * read.c: New procedure: scm_read_options
8737 * read.h: Defines for reader options.
8739 * root.h: Added scm_source_whash among scm_sys_protects.
8741 * srcprop.c: New file: source properties.
8743 * srcprop.h: New file: source properties.
8745 * throw.c (jbsmob): Jump buffers are now correctly allocated.
8746 (Bug found by A. Green.)
8748 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8750 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8752 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8754 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8756 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8757 and should be called by the final client.
8759 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8761 * gc.h: Use the PROTO macro when declaring functions.
8762 * gc.c: Use the PROTO macro when declaring static functions.
8763 Remove the CPP hair around function definitions.
8765 * gc.c (scm_init_storage): Initialize scm_asyncs.
8767 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8768 preprocessor symbol; "__scm.h" is where it might get #defined.
8769 * __scm.h: Similar: #include <scmconfig.h> before testing
8772 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8774 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8776 * init.c (scm_boot_guile): Add init_func argument; call
8777 (*init_func) instead of calling scm_appinit; it's ucky to
8778 hard-code names for the user's procedures.
8779 * init.h (scm_boot_guile): Adjust declaration.
8781 * __scm.h (PROTO): New macro, for declaring functions with
8784 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8785 eliminate all the __STDC__ conditionals.
8786 (scm_boot_guile): Add declaration.
8787 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8788 Remove __STDC__ conditionals around function definitions; the
8789 declarations in init.h will provide the same information, more
8792 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8793 complain about it in the error message; the error message is
8794 adequate without that note, and there's nothing the user can do
8797 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8799 * Makefile.in (ancillary): Drop def.sed.
8801 * posix.c (scm_init_posix): Use numeric values, rather than
8802 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8803 F_OK. The symbols aren't available on some systems, and I'm
8804 pretty sure their values are fixed by common widespread practice.
8805 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8807 More functions unavailable on some systems.
8808 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8809 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8811 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8812 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8813 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8814 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8815 stub that signals an error as the #else.
8817 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8819 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8821 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8823 * unif.c: include ramap.h.
8825 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8827 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8829 * ports.c: include sys/ioctl.h.
8831 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8833 * configure.in: check for sys/ioctl.h.
8835 * ports.c: include <malloc.h> not "malloc.h".
8837 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8839 * fports.c: remove ttyname and tmpnam declarations.
8841 * posix.c: fewer ttyname declarations.
8843 * fports.c: include <string.h> not "string.h".
8845 * init.c, ioext.c: include string.h and unistd.h.
8847 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8849 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8850 genio.c, simpos.c, vports.c: include string.h.
8852 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8854 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8856 (scm_addr_buffer_size): change type from scm_sizet to int.
8857 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8858 from scm_sizet to int.
8860 * error.c: include unistd.h.
8862 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8865 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8867 * __scm.hd, def.sed: deleted.
8869 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8871 Changes for NeXT, suggested by Robert Brown.
8872 * configure.in: Call AC_TYPE_MODE_T.
8873 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8874 NeXT. Put header file list in alphabetical order.
8875 * configure, scmconfig.h.in: Regenerated.
8876 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8878 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8881 * acconfig.h: New file, providing documentation for the CPP
8882 symbols defined in configure.in
8883 * acconfig-1.5.h: Removed; superceded by the above.
8885 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8887 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8889 * fports.c (scm_open_file): don't return #f, throw error.
8891 * ioext.c (fileno): renamed from %fileno.
8892 (soft-fileno): deleted.
8894 * ports.c (scm_port_revealed): don't need to check for -1 from
8896 (scm_set_port_revealed_x): return unspecified, not #f.
8898 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8900 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8902 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8904 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8906 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8908 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8909 This is necessary on Ultrix, and doesn't hurt portability.
8911 * Makefile.in (dist-dir): New target, implementing a new dist system.
8912 (installed_h_files): Put in alphabetical order.
8913 Remove duplicate entries for markers.h and unif.h.
8914 (c_files): Remove duplicate entries for markers.c.
8915 (ancillary): Renamed from anillery; all uses changed. Remove
8916 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8917 Remove all the ../doc/* files; doc/Makefile.in handles that.
8919 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8921 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8922 every if must have an else, or else the whole command has a
8923 non-zero exit code whenever the if's condition is false.
8925 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8927 * posix.c: include string.h.
8929 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8931 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8934 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8935 Remove leading % from scheme names.
8936 Do not return error values, call SCM_SYSERROR or similar.
8938 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8940 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8942 * struct.c (scm_init_struct): new file.
8944 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8946 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8947 (scm_list_head): added list-head for rapidly chopping argument
8948 lists off of longer lists (and similar).

8952 * objprop.c (scm_object_property): assq the cdr of the whash
8953 handle for obj, not the handle itself.
8955 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8957 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8958 weak hash tables last of all marking to avoid an obscure gc bug.
8959 WARNING: circular lists stored in a weak hash table will hose us.
8961 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8963 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8964 new functions similar to scm_substring_move_left_x and
8965 scm_substring_move_right_x.
8967 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8969 * init.c (scm_boot_guile): prevent gc with scm_block_gc not

8974 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8976 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8978 * strports.c (scm_strprint_obj): convenience function. C for
8979 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8981 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8982 removed to a separate library
8984 * init.c (scm_boot_guile): copied from guile-tcl.c.
8985 Initialization specific to tcl interpreters removed.
8987 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8989 * ports.c (scm_ports_prehistory): size malloced here doesn't
8990 matter so long as it is non-0 (got rid of "* 4").
8992 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8994 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8995 since its definition was bogus).
8997 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8999 * mallocs.[ch]: back again (for rx at least).
9001 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
9003 * ports.c: removed functions relating to the mapping between ports
9004 and descriptors. (That stuff is unix-specific and should be collected
9005 in a separate library).
9007 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
9008 (Tom Mckay@avanticorp.com)
9010 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
9012 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
9013 handled correctly (SCM_FREEP was applied to them) -- test for
9014 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
9015 being overwritten with #f. (brown@grettir.bibliotech.com)
9017 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
9019 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

9022 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
9024 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak

9034 Generalized assoc and hash-table functions.
9035 Factored pairs.c into multiple files.
9037 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
9039 * gscm.c (gscm_run_scm): got rid of objprop.
9041 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>

9058 * vports.c (scm_make_soft_port): allocate a port table entry
9059 (possibly triggering gc) before setting the tag of the corresponding
9062 * pairs.c (scm_delq_x): never throw an error.
9064 * vectors.c (scm_make_vector): made the default vector fill argument
9065 into '() (much more useful than the previous value, "#unspecified")
9067 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
9069 * ports.c (scm_add_to_port_table): Added fields
9070 to port table entries: file_name, line_num, col.
9071 Update these in open_file, gen_getc and gen_ungetc.
9072 Added procedures to access those fields.
9074 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
9076 * procs.c (scm_make_subr_opt): new entry point for making

9090 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
9091 (scm_gc_stats): return an assoc of useful data. Replaces "room"
9092 and the stats reporting formerlly built into repl.

9096 Other statistics keeping can be done from Scheme.
9097 REPLS are now written in Scheme.

9106 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
9108 * feature.c (scm_compiled_library_path): moved here from repl.c.
9109 This file is for stuff relating specifically to Scheme libraries
9112 * eval.c (scm_m_define): don't give warning about redefinition, don't
9115 NOTE: this should throw a resumable exception with parameters --
9116 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
9118 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
9120 * error.c: scm_warn eliminated.

9139 * strports.c: don't reveal the port's string to the caller
9140 because it changes size.
9142 (stputc stwrite): check/change the strings length with interrupts
9145 * objprop.c (scm_set_object_property_x &c): use the generic
9146 hashing functions and be threadsafe.
9148 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
9149 (per suggestion jaffer@gnu.ai.mit.edu).
9151 * mbstrings.c (scm_multi_byte_string): guard against argument list
9154 * strings.c (scm_make_string): loop cleanup

9182 initialization to fix a race condition.
9184 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
9185 object, not in a global.
9186 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)

9205 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
9207 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
9208 set the multi_byte flag correctly in symbols. This is wrong.
9209 intern_obbary_soft and msymbolize should take an extra parameter.
9210 Also, weird multibyte symbols don't print correctly.
9211 The weird symbol syntax is also a bit bogus (emacs doesn't quite
9214 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
9216 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
9217 use the system symhash. == #t means create an uninterned symbol.
9219 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
9221 * strings.c (scm_make_shared_substring): build'em.
9222 It might better to keep a table of these and use one
9223 less cons-pair per shared-substring.

9293 * lvectors.c (scm_get_lvector_hook):
9294 In guile-ii, the lvector code was broken. It was fixed in guile-iii.
9295 It seems to me like if it is broken again in guile-iv...Here is a patch.
9296 "! || (LENGTH (keyvec) == 0))"
9297 (From: Mikael Djurfeldt <mdj@nada.kth.se>)
9300 * gscm.c (gscm_sys_default_verbosity):
9301 incorrectly declared for non-__STDC__
9302 (Tom_Mckay@avanticorp.com)
9304 * ports.c (scm_setfileno): Tweak the macro a bit
9305 to make it easier to port to systems that use
9306 more than a single structure field to hold a descriptor.
9308 * debug.c (change_mode): Avoid GNUCism "int foo[n];"
9309 Give a warning, not an error, for unrecognized modes.
9311 * eval.c (SCM_CEVAL):
