[bpt/guile.git] / libguile / ChangeLog
1 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2
3 * posix.c: don't include <sys/select.h> or define macros for
4 select, since they were not used in this file.
5
6 * * filesys.c (scm_select): make the fifth parameter microseconds,
7 not milliseconds. let the fourth parameter be either a real value
8 or an integer or #f. The first, second and third arguments can
9 now be vectors: the type of the corresponding return set will be
10 the same.
11 (set_element, get_element): new static procedures.
12
13 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
14
15 * strports.c (scm_eval_string): New function.

24
25 From Tim Pierce:
26 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
27 Use a meaningful error message when signalling an error. For
28 this, scm_gethost must check h_errno rather than errno.
29
30 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
31
32 * Makefile.in: Regenerated, using automake-1.1p.
33
34 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
35
36 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
37 not SCM_UNSPECIFIED.
38
39 * script.c (scm_compile_shell_switches): don't append (quit) if
40 interactive.
41 (scm_shell): call scm_exit_status and exit on the result of the
42 evaluation.
43
44 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
45

47 a system call or other foreign function. Many thanks to Tim
48 Pierce!
49 * symbols.h (SCM_COERCE_SUBSTR): new macro.
50 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,

55 (scm_display_error_message): use RO macros when strings may be RO.
56 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
57 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
58 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
59 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
60 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
61 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
62 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
63 scm_strftime), vports.c (scm_make_soft_port): use
64 SCM_COERCE_SUBSTR to make sure shared substrings are
65 null-terminated.
66
67 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
68
69 * error.c (scm_error): Add newline to error message.
70
71 * init.c (scm_init_standard_ports): Doc fix.
72
73 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>

79 (scm_compile_shell_switches): Use it.
80
81 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>

87 calling gmtime in case they share a buffer.
88 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
89 nor HAVE_TZNAME.
90
91 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
92
93 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
94
95 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
96
97 * Makefile.am (check-local): New target, which causes 'make check'
98 to run gh_test_c and gh_test_repl, with some trivial input.
99 * Makefile.in: Rgnrtd.
100
101 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
102
103 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
104 been unlinked.
105
106 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
107
108 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
109 sure how this was supposed to work.
110 (scm_async_click): don't send SCM_TICK_SIGNAL.
111 (scm_init_async): don't initialize %tick-thunk.
112
113 * the following change doesn't affect the Scheme interface:
114 gc-thunk is called at the end of garbage collection. however it's
115 no longer implemented by pretending it's a signal.
116
117 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
118 system async corresponding to scm_gc_thunk.
119 * async.h: declare scm_gc_async.
120 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
121 gc-thunk directly, instead of going through a signal handler.
122 (scm_gc_async): new variable, points to the GC system-async.
123 (scm_init_async): save the GC async as scm_gc_async instead
124 of using system_signal_asyncs.
125 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
126
127 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
128
129 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
130 Don't screw up if we're interrupted.
131 * Makefile.in: Regeneradet.
132
133 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
134
135 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
136
137 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
138 we're not using AM_INIT_GUILE_MODULE any more.
139 * Makefile.in: Reneregated.
140
141 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
142
143 Functions for finding variable bindings, grace à Tim Pierce.
144 * * gh_data.c (gh_lookup, gh_module_lookup): New functions.
145 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
146
147 Get 'make dist' to work again.
148 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
149 * Makefile.in: Regenerated, like a surry without a fringe on top.
150
151 Changes for reduced Guile distribution: one configure script,
152 no plugins.
153 * configure.in, configure: Removed.
154 * acconfig.h, acinclude.m4: Moved to parent directory, where the
155 real configure script lives.
156 * Makefile.in, scmconfig.h.in: Regenerated.
157
158 * init.c: #include "script.h", to get prototype for script.c's
159 init function.
160
161 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
162
163 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
164 scm_must_malloc, not raw malloc.
165
166 * script.c (scm_compile_shell_switches): Dyke out debugging output
167 code.
168
169 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
170
171 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
172
173 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
174 system has them. Hope this is safe. Previously
175 sys/timeb.h was included if HAVE_FTIME was defined or if
176 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
177 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
178
179 * ioext.c (scm_setfileno): add missing third argument to
180 scm_misc_error call.
181
182 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
183
184 * eq.c (scm_equal_p): Correctly compare strings of different
185 varieties. (Thanks to Tim Pierce.)
186
187 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
188
189 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
190 #! block comment must occur on a line all by itself.
191
192 Move most of the guts of shell command processing into libguile,
193 so guile.c can be very small (and eventuallly auto-generated. (I
194 mean, generated mechanically, not self-generated. Hmm.))
195 * guile.c, script.c, script.h: New source files.
196 * init.c (scm_boot_guile_1): Call scm_init_script.
197 * libguile.h: #include "script.h".
198 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
199 targets, for new executable.
200 (libguile_la_SOURCES): Mention script.c.
201 (modinclude_HEADERS): Add script.h.
202 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
203 not dynamic linking is enabled. This is because we're generating
204 executables now. Move CY_AC_WITH_THREADS call after those, so the
205 values of cy_cv_threads_libs captures the libs chosen above.
206 * Makefile.in, configure, aclocal.m4: Regenerated.
207
208 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
209 We don't maintain this interface any more, and it just confuses
210 people.
211
212 * alloca.c: #include <scmconfig.h>, not <config.h>.
213 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
214 it'll get included in disties.
215
216 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
217
218 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
219 be distributed, because they confuse people.
220 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
221
222 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
223
224 * configure.in: check for presence of gethostent (not present on
225 OpenBSD by default).
226 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
227 * configure, scmconfig.h.in: Regenerated.
228
229 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
230
231 * backtrace.c (scm_backtrace): Split message string across
232 newlines properly. GCC is more tolerant of this than other
233 compilers.
234
235 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
236
237 Merge threads directory into libguile.
238 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
239 threads.h: New source files.
240 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
241 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
242 here; see comment.
243 (modinclude_HEADERS): Add threads.h, coop-defs.h.
244 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
245 coop-threads.c.cygnus, coop-threads.h.cygnus.
246 * configure.in: If we're using threads, include threads.o in
247 LIBOBJS.
248 * _scm.h, libguile.h: threads.h lives in this directory now.
249 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
250 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
251 currently used, but brought along for information's sake.
252 * ChangeLog-threads: log from old 'threads' directory.
253 * Makefile.in, configure: Rebuilt.
254
255 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
256
257 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
258 lt->tm_zone.
259
260 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
261
262 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
263
264 Merge GH interface library into libguile.
265 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
266 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
267 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
268 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
269 _scm.h to ...
270 (EXTRA_libguile_la_SOURCES): ... here.
271 (pkginclude_HEADERS): Add variable, to get gh.h installed.
272 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
273 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
274 New variables, describing how to build the gh test programs.
275 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
276 build the test programs, and we probably should have been linking
277 libguile.la against them all along, to support AIX shared libs.
278 Add cflags for threads to CFLAGS; add libs for threads to new
279 variable THREAD_LIBS, used in Makefile.am.
280 * ChangeLog-gh: log from old `gh' subdirectory.
281 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
282
283 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
284
285 * acconfig.h: Undo change of Apr 9; including the definition of
286 PACKAGE in the guile headers conflicts with applications' own
287 definitions.
288 * scmconfig.h.in: Regenerated.
289
290 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
291

293 (scm_init_filesys): New symbols for use with fcntl.
294 * filesys.h: Added prototype.
295
296 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
297 when PROC is receiving no arguments.
298
299 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
300
301 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
302 have S_IFSOCK. This is the case under Ultrix.
303
304 * posix.c (scm_status_exit_val, scm_status_exit_val,
305 scm_status_term_sig, scm_status_stop_sig): Modified to work with
306 Ultrix versions of WIFSTOPPED, etc., which assume that their
307 arguments are lvalues (hmm).
308
309 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
310
311 * eval.c: Doc fixes.
312
313 * throw.c: Doc fixes; rearranged.
314
315 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
316
317 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
318
319 * acconfig.h: Added entry for PACKAGE.
320 * scmconfig.h.in: Regenerated.
321
322 Changes to work with automake-1.1n, which has better libtool support.
323 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
324 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
325 difference here?)
326 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
327 readability.
328 * Makefile.in: Rebuild.
329
330 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
331
332 * stime.c (scm_mktime): take an optional zone argument.
333 (scm_localtime): check putenv return value.
334 (scm_strftime, scm_strptime): moved from posix.c. move #include
335 sequences.h too.
336 stime.h, posix.h: update prototypes.
337 (bdtime2c, setzone, restorezone): new static procedures.
338 (scm_mktime, scm_strftime): use them.
339 (scm_strftime): don't call mktime before strftime. Use
340 filltime for return value.
341 (filltime): convert NULL zname to #f.
342 * (scm_strptime): return a count of characters consumed, not
343 the remaining string.
344
345 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
346
347 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
348 (scm_mktime): likewise.
349 Declare *tzname[].
350 Uncomment localtime and mktime.
351
352 * configure.in: add AC_STRUCT_TIMEZONE.
353
354 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
355
356 * stime.c (scm_init_stime): don't define ticks/sec.
357 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
358 return value problem and is still portable.)
359
360 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
361
362 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
363 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
364 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
365 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
366 cpp_err_symbols.c): Corresponding changes.
367 * Makefile.in: Regenerated.
368
369 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
370
371 * posix.c (scm_putenv): don't check HAVE_PUTENV.
372 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
373 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
374 * putenv.c: new file, from sh-utils 1.12.
375
376 * posix.c (scm_environ): use malloc in place of scm_must_malloc
377 since allocation isn't for Scheme objects.
378 (scm_putenv): copy strings before placing in the environment.
379
380 * stime.c (scm_current_time): throw an error if time returns -1,
381 instead of returning #f.
382 (scm_get_internal_real_time, scm_get_internal_real_time): use
383 scm_long2num for return value instead of SCM_MAKINUM.
384
385 * stime.h: prototypes updated.
386
387 * stime.c (scm_time_in_msec): apparently unused, deleted.
388
389 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
390
391 * configure.in: check for gettimeofday.
392
393 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
394 which may be more usefully portable than a gettimeofday interface.
395
396 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
397
398 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
399 cpp_err_signals.
400 * Makefile.in: Regenerated.
401
402 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
403
404 * stime.c (filltime): recovered static procedure.
405 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
406 an earlier Guile.
407
408 * posix.h: add prototype for scm_close_pipe, remove prototypes for
409 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
410
411 * * posix.c (scm_mknod): split the mode argument into type and perms
412 arguments, like the extra fields returned by stat.
413
414 * fports.c (scm_pipob): set the close, free and print procedures.
415 (scm_close_pipe): new procedure.
416
417 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
418 define them in boot-9.scm
419
420 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
421
422 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
423 wan't defined. Don't include fd.h.
424
425 * Previously fd.h was regenerated whenever configure was run,
426 forcing a couple of files to be recompiled.
427
428 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
429 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
430 Check for _fileno as well as _file.
431 Don't output fd.h.
432 * ioext.c: don't fd.h.
433 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
434 other to FD_SETTER.
435
436 * Change the stratigy for getting information about errno
437 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
438 generating lists of symbols during the build process, which will
439 not always work, include comprehensive lists in the distribution.
440 To help keep the lists up to date, the "check_signals" and
441 "check_errnos" make targets can be used.
442
443 * configure.in: don't check for a command to extract errno codes.
444 * Makefile.am: update file lists, remove errnos.list and errnos.c
445 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
446 check_errnos targets.
447 (CLEANFILES): remove errnos.c and errnos.list, add
448 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
449 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
450 * errnos.default: deleted.
451 * cpp_signal.c: new file.
452 * cpp_errno.c: renamed from errnos_get.c.
453 * cpp_err_symbols, cpp_sig_symbols: new files.
454 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
455 * error.c (scm_init_error): #include cpp_err_symbols instead of
456 errnos.c.
457 * posix.c (scm_init_posix): don't intern signal symbols. #include
458 cpp_sig_symbols.c.
459
460 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
461
462 * strop.c (scm_i_index): allow the lower bound to be equal to the
463 length of the string, so a null string doesn't always give an error.
464
465 * posix.h: new prototypes.
466 * posix.c (scm_status_exit_val, scm_status_term_sig,
467 scm_status_stop_sig): new functions, as in scsh. They break down
468 process status values as returned by waitpid.
469
470 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
471
472 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
473 configure doesn't know about it.
474
475 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
476
477 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
478
479 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
480 which defines C variables with global linkage.
481
482 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
483
484 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
485 zero arg subrs.
486
487 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
488
489 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
490 has time to check why this doesn't work well with continuations.
491
492 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
493
494 * Fix shell syntax error; some shells won't tolerate
495 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
496
497 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
498
499 * posix.c (scm_uname): throw an error if uname fails instead
500 of returning errno.
501
502 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
503
504 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
505 removed.
506
507 * async.c (scm_ints_disabled): definition moved from error.c.
508
509 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
510
511 * acconfig.h: Removed PACKAGE.
512
513 * scmconfig.h.in: Regenerated.
514
515 * snarf.h: g++ says it's non-portable not to specify the first
516 argument in a varargs declaration. I introduced the first
517 argument by using preprocessor conditionals.
518
519 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
520
521 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
522 (scm_freopen): use RO string macros for filename and modes.
523 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
524
525 * posix.c (scm_getgrgid): simplify conversion of name to C string.
526 (scm_mknod): use RO string macros for path.
527
528 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
529 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
530
531 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
532 use SCM_ROSTRINGP and SCM_ROCHARS.
533
534 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
535
536 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
537 a scm_tc7_byvect.
538
539 * ramap.c (scm_ra_matchp, scm_ra_matchp, scm_array_fill_int, racp,
540 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
541 support for byte vectors.
542
543 * print.c (scm_iprin1): Limit number of vector elements printed
544 according to pstate->length.
545
546 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
547
548 * backtrace.c (scm_display_error_message): don't segv if message
549 is an immediate.
550
551 * error.h: prototype for scm_error_scm.
552
553 * error.c (scm_error_scm): new procedure, reimplements scm-error
554 in C and uses scm_error.
555
556 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
557
558 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
559 pointer to the Scheme variable read-hash-procedures and intern it
560 in scm_init_read. Modify scm_read_hash_extend and
561 scm_get_hash_procedure to use the pointer.
562
563 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
564
565 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
566 (SCM_KEYWORD_STYLE): defined.
567
568 * read.c (scm_read_opts): add a keywords option. This isn't a
569 boolean option, in case someone wants to add support for DSSSL
570 keywords too.
571 Setup scm_keyword_prefix symbol.
572 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
573 set to 'prefix.
574 * I've left keyword support disabled by default, since it doesn't
575 seem to break the module system and it gives R4RS standard behaviour.
576 It can be reactivated with (read-set! keywords 'prefix).
577
578 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
579
580 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
581 before constructing arbiter.
582
583 * eval.c (scm_m_define): Bugfix: Check that the object is a
584 closure before setting the procedure property!
585
586 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
587
588 * ports.c: Removed `ungetc-char-ready?'.
589
590 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
591
592 * read.c (scm_init_read): intitialise scm_read_hash_procedures
593 (idea from Mikael: make it a pair so scm_permanent object only
594 called once.)
595 (scm_read_hash_extend): don't call scm_permanent_object.
596 (ideas from Mikael): if chr is already in the list, replace its
597 procedure instead of appending it again. If proc is #f, remove
598 it from the list.
599 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
600
601 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
602
603 * gdbint.c (gdb_read): update scm_lreadr usage.
604
605 * load.h: update prototypes.
606
607 * load.c (scm_primitive_load, scm_read_and_eval_x,
608 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
609
610 * read.h: add prototype for scm_read_hash_extend. Change args for
611 other prototypes.
612
613 * read.c (scm_read_hash_procedures): new variable.
614 (scm_read_hash_extend): new procedure.
615 (scm_get_hash_procedure): new procedure.
616 * (scm_lreadr): use scm_get_hash_procedure instead of an argument
617 for extended # processing.
618 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
619 scm_read_token): remove case_i, sharp arguments. Change callers.
620
621 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
622
623 * read.h (SCM_N_READ_OPTIONS): increase to 3.
624 (SCM_CASE_INSENSITIVE_P): define.
625
626 * read.c: add case-insensitive option to scm_read_opts.
627 * (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
628 to determine whether to convert symbol case.
629 (default_case_i): definition removed.
630 * read.c (scm_read_token): if case_i, downcase ic before doing
631 anything with it.
632
633 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
634
635 * configure.in: Added configuration option `guile-debug'.
636 Configure with --enable-guile-debug if you want a bunch of extra
637 functions used for debugging when developing Guile.
638
639 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
640
641 * procs.c (make-cclo): New undocumented debugging procedure: Make
642 compiled closure with internal procedure PROC and length LENGTH.
643 Only compiled if GUILE_DEBUG is defined.
644
645 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
646
647 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
648
649 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
650
651 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
652 with 3 or more args internally to the evaluator.
653
654 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
655
656 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
657 with 3 or more args internally to the evaluator. This is mainly
658 because we don't want to pass entry and exit points of the
659 debug support twice, but it also seems to increase the speed of
660 the evaluator for such calls (e. g. (+ 1 2 3)).
661
662 * * backtrace.c (scm_display_application): New procedure:
663 display-application; Set fancy printing parameters individually
664 for different types of display (backtrace, error, application).
665 (These should of course be customizable!)
666
667 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
668 clear the CHECK-flags.
669
670 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
671
672 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
673
674 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
675
676 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
677 from pairs with a GLOC in the car.
678
679 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
680 otherwise `symbol-hash' will behave badly.
681 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
682 we get segmentation fault!
683
684 * * symbols.c: Added #include "weaks.h". New functions:
685 `builtin-bindings' and `builtin-weak-bindings'. (These will be
686 moved to an extraneous library when we split libguile.)
687
688 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
689
690 * filesys.c (scm_stat): stat now takes fport arguments too as
691 documented in the manual.
692
693 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
694
695 * debug.c (scm_single_step): Bugfix: Call continuation with
696 scm_call_continuation instead of throwing to it.
697
698 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
699
700 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
701 argument wasn't declared to be optional.
702
703 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
704
705 * stime.c (scm_init_stime): Add feature "current-time".
706
707 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
708
709 * throw.h: prototype for scm_exit_status.
710 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
711 args to derive an exit status. Allows (quit) to work from a
712 script.
713 (scm_exit_status): new function.
714 #include "eq.h".
715
716 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
717
718 * eval.c (scm_deval): Removed some old code.
719 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
720 with the others.
721 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
722 exit-frame traps.
723
724 * symbols.c (msymbolize): Bugfix: Must initialize property list to
725 SCM_EOL.
726
727 * procs.c: Introduce the existent C function scm_thunk_p at the
728 Scheme level as well.
729
730 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
731
732 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
733 used from C to easily lookup the value of a symbol in the current
734 module.
735
736 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
737
738 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
739 scm_init_unif in this file. This will also fix a previous problem
740 with guile-snarf.)
741
742 * configure.in: Added AM_MAINTAINER_MODE
743
744 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
745
746 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
747 avoid warnings.
748
749 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
750
751 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
752 source files that are not always included in libguile but should
753 have their dependencies calculated by automake. This variable is
754 recognized by automake, no further magic is needed.
755 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
756 to deal exclusively with *.lo files, as it seems. The *.o files
757 are built automatically when the corresponding *.lo file gets
758 built.
759
760 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
761
762 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
763 exists.
764
765 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
766
767 * unif.c (scm_array_set_x): minor change to argument error checking.
768
769 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
770
771 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
772 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
773 They should only be included in the library at configure.in's
774 discretion.
775 (libguile_la_LDADD): Include the appropriate .lo files here.
776 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
777 so we know when to build them (and their .lo bretheren).
778 * configure.in (LIBLOBJS): New substituted variable. We let
779 configure decide which .o files to include in LIBOBJS, and then
780 put the corresponding list of .lo files in LIBLOBJS. The latter
781 is what we pass to libtool.
782 * Makefile.in, configure: regenerated.
783
784 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
785
786 * symbols.c (scm_sysintern0): New function. Contains the core of
787 old scm_sysintern but doesn't take a second value argument.
788 (scm_sysintern): Now uses scm_sysintern0.
789 (scm_sysintern_no_module_lookup): Renamed to
790 scm_sysintern0_no_module_lookup and doesn't take a second value
791 argument any longer.
792
793 * symbols.h (scm_sysintern0: Added declaration.
794
795 * options.c (scm_init_opts): Use scm_sysintern0 instead of
796 scm_sysintern when interning option keys. Otherwise we risk
797 destroying the values of already interned variables.
798
799 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
800 scheme-level boolean (use SCM_NFALSEP).
801
802 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
803 `the-last-stack'.
804 (scm_backtrace): New function. (C version of old function from
805 boot-9.scm) Motivation: Make it possible to display backtraces
806 without depending on boot-9.scm. (I'm uncertain if this
807 motivation is good enough...)
808
809 * root.h (scm_root_state): Add member the_last_stack_var.
810 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
811
812 * root.c (mark_root): Mark scm_the_last_stack_var.
813
814 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
815 SCM_BOOL_F.
816
817 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
818
819 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
820 1. mark_lazy_catch didn't mark the smob.
821 2. Both functions above have standard variants:
822 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
823 free_lazy_catch --> scm_free0.
824
825 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
826
827 * throw.c (scm_internal_lazy_catch): New function.
828 (scm_lazy_catch): Rewritten to use it.
829 (scm_ithrow): Handle the new lazy catch representation.
830 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
831 that doesn't have a jmpbuf is a lazy catch clause.
832 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
833 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
834 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
835 smob.
836 (scm_init_throw): Register the new lazy-catch smob type.
837 * throw.h (scm_internal_lazy_catch): decl for new function.
838
839 * throw.c (scm_internal_catch): Doc fixes.
840
841 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
842 configure.in. Including this might cause problems if applications
843 that link against libguile include their own copies of alloca, but
844 if they're using autoconf, they should be adding libguile to LIBS
845 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
846 the copy in libguile, and things will be okay. (I think.)
847
848 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
849
850 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
851 unif.c.
852 strop.h: move prototypes too.
853
854 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
855
856 * posix.c (scm_init_posix): don't intern EINTR since it's now done
857 elsewhere.
858
859 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
860 etc. I deleted them from filesys.c long ago, but didn't
861 notice they were here too (although ineffective since
862 sys/stat.h wasn't included).
863
864 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
865
866 * eval.c: Don't define alloca in GCC case. gcc will automatically
867 use __builtin_alloca if appropriate.
868
869 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
870
871 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
872 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
873 that values of automatic variables are preserved. See comments
874 for safe_setjmp for details.
875
876 Change from Thomas Morgan:
877 * variable.c: Include eq.h.
878 (var_equal): New function.
879 (variable_smob): Use var_equal as the discriminator for variables.
880
881 * throw.c (s_throw): Remove extraneous declaration.
882
883 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
884 * eval.c: Add necessary CPP cruft to support that.
885 * configure, Makefile.in, scmconfig.h.in: regenerated.
886
887 Change from Thomas Morgan:
888 * procprop.c (scm_procedure_properties): Convert the Scheme
889 boolean returned by scm_procedure_p into a C boolean before using
890 it as a condition for SCM_ASSERT.
891 (scm_procedure_property): Likewise.
892
893 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
894 indications of Unixness.
895 * stime.c: Same.
896
897 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
898
899 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
900
901 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
902
903 * read.c (scm_lreadr): use scm_misc_error to improve one of the
904 "unknown # object" error messages.
905
906 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
907 (scm_i_index) and declare it static. Add a 'direction' argument
908 to indicate what way the search should go.
909 (scm_i_index): throw out-of-range error instead of wrong-type-arg
910 if indices are bad.
911 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
912 strop.h: remove scm_i_index, scm_i_rindex prototypes.
913
914 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
915
916 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
917
918 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
919 to avoid clash with various scsh forks.
920
921 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
922
923 The following two changes (ramap.c, throw.c) are motivated by the
924 apparent unportability of forward declarations of static arrays of
925 the form `static foo bar[];'.
926
927 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
928 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
929
930 * throw.c (scm_throw): Moved above scm_ithrow.
931
932 * options.h: Removed the extern declarations of scm_yes_sym and
933 scm_no_sym since these are static.
934
935 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
936
937 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
938
939 * Makefile.am: remove AWK=@AWK@.
940 Add a rule for generating errnos.list.
941 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
942
943 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
944 don't extract errnos, just set a variable (avoids the
945 need to recompile error.c just because configure is run.)
946
947 * unif.h: update prototypes.
948 * unif.c (scm_uniform_array_read,write): change the offset and
949 length arguments to start and end, for consistency.
950
951 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
952
953 * ioext.h: update prototypes.
954 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
955 scm_read_line_x, it's a more general procedure using an
956 interface from scsh. read-line and read-line! are now defined
957 in boot-9.scm.
958 * Note that the new read-line trims the terminator
959 by default, previously it was appended to the returned string. An
960 optional argument specifies how to process the terminator (scsh
961 compatible). For the old behaviour: (read-line port 'concat).
962 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
963 returns a pair, but is converted to multiple values if the scsh
964 module is loaded.
965
966 socket.h: update prototypes.
967 * socket.c (scm_recvfrom): for consistency with other procedures,
968 take start and end as separate optional arguments.
969 * (scm_recv, scm_recvfrom): don't allow the second argument
970 to be a size, only a buffer. Change the scheme names to
971 recv! and recvfrom!. Don't return the buffer.
972
973 * ioext.h, posix.h: move prototypes too.
974 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
975 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
976 "read.h" and "unif.h".
977 * ioext.c: include "chars.h"
978
979 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
980
981 * dynl.c: The dynamic linking and module registration functions
982 are now defined even when dynamic linking is not available for the
983 host system. Some of their functionality can be done without
984 dynamic linking; when it's really needed, they throw errors.
985
986 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
987
988 * configure.in: Only define DYNAMIC_LINKING when one of the system
989 dependent functions is detected.
990 * dynl.c (scm_dynamic_func): New function to get the address of a
991 function in a dynamic object.
992 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
993 produced by scm_dynamic_func as the thing to call.
994
995 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
996
997 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
998 (scm_register_module_xxx, scm_registered_modules,
999 scm_clear_registered_modules): New functions.
1000
1001 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
1002
1003 * symbols.c (scm_sysintern): Renamed to
1004 scm_sysintern_no_module_lookup.
1005 (scm_sysintern): New function to take the place of the old
1006 scm_sysintern. It uses the current toplevel lookup closure to give
1007 the symbol its value. This is a temporary hack to put packages
1008 like gtcltk into their own module.
1009 (scm_can_use_top_level_lookup_closure_var): New variable to tell
1010 us whether `scm_top_level_lookup_closure_var' has been initialized
1011 and is usable.
1012 * eval.c (scm_init_eval): Set it.
1013
1014 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1015
1016 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
1017 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
1018 SCM_FD.
1019 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
1020 scm_syserror_msg.
1021 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
1022 scm_sys_dup): deleted: FD capability will be added to other
1023 procedures.
1024 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
1025 scm_fd_free, fd_smob, scm_intern_fd.
1026 * (scm_open): renamed from scm_sys_open. Return a port instead of
1027 an FD object. Make the mode argument optional.
1028 * (scm_sys_create): deleted, it's just a special case of open.
1029 (scm_init_filesys): move interning of constants O_CREAT etc.,
1030 here (were previously using SCM_CONST_LONG macro).
1031 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
1032 don't newsmob fd.
1033 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
1034 include "fports.h" and <stdio.h>
1035 (scm_stat, scm_select): don't support FD objects.
1036
1037 * error.h: adjust scm_syserror_msg prototype.
1038 * error.c (scm_syserror_msg): take an extra argument for errno.
1039 Using the global value didn't always work, since it could be
1040 reset by procedure calls in the message or args arguments.
1041
1042 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
1043 I don't understand why the check was there (and what about the
1044 ultrix check?)
1045
1046 * strop.c (scm_string_copy): allow shared substrings to be copied.
1047
1048 * unif.h: corresponding change to prototypes.
1049 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
1050 recognize two new optional arguments: offset and length. Allow
1051 the port argument to be an integer (file descriptor, for scsh).
1052 Include <unistd.h> for "read" prototype.
1053
1054 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1055
1056 * socket.c: don't include filesys.h.
1057
1058 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
1059
1060 * Makefile.am: add AWK=@AWK@ (?)
1061
1062 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
1063 errnos_get.c.
1064 Add a rule to generate errnos.c from errnos.
1065 * error.c (scm_init_error): include errnos.c.
1066 * errnos_cnvt.awk: new file, converts the list of errno codes to
1067 C expressions.
1068 * errnos_get.c: new file.
1069 * errnos.default: new file, contains errnos to try if they can't
1070 be extracted from errno.h.
1071 * configure.in: if using GCC, try and extract errno codes from
1072 errno.h.
1073 Added AC_PROG_AWK.
1074
1075 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
1076
1077 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
1078 * Makefile.am: Made libguile into a libtool library.
1079 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
1080 Set libtool_libs to indicate that libguile is a libtool library.
1081 See guile/ChangeLog for details.
1082 * .cvsignore: ignore "*.lo", the libtool library objects.
1083
1084 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1085
1086 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
1087 use htons in getservbyport argument.
1088
1089 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1090
1091 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
1092 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
1093 duplicate.
1094
1095 * objprop.c (scm_object_property): No need to take the CDR of the
1096 value returned by scm_object_properties, since Aug 20 change.
1097
1098 * configure.in: When checking for struct linger, #include
1099 <sys/types.h> as well as <sys/socket.h>. I've never known
1100 <sys/types.h> to cause any portability problems, and Solaris's
1101 <sys/socket.h> needs it.
1102 * configure: Rebuilt.
1103
1104 I think the Sun compiler has chosen a perverse way to interpret
1105 ANSI declarations combined with K&R definitions. We'll
1106 appease it a little bit. But when it invades France, we fight.
1107 * print.c (scm_iprlist): Change 'tlr' argument to an int.
1108 * print.h (scm_iprlist): Here too.
1109 * numbers.c (scm_divbigdig): Change definition to match
1110 declaration in numbers.h.
1111 * unif.c (scm_makflo): Change definition to match declaration in
1112 unif.h.
1113
1114 * init.c (scm_boot_guile): Don't return the value of
1115 scm_boot_guile_1. This function doesn't return a value;
1116 scm_boot_guile_1 doesn't return a value (or return at all).
1117
1118 * eval.c (unmemocopy): Add a semicolon to appease the Sun
1119 compiler.
1120
1121 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
1122 compile. I have a feeling this function is a bad idea anyway ---
1123 one should always test for features, not systems.
1124
1125 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
1126 semicolons. Only pure luck kept this from being noticed earlier.
1127
1128 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
1129
1130 * socket.c (scm_recvfrom): Added missing semicolon.
1131
1132 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1133
1134 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
1135 the buffer and start and end positions for scsh networking
1136 implementation.
1137
1138 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
1139
1140 * configure.in: Revert previous change to this file; the problem
1141 is due to transient automake weirdness.
1142 * configure: Rebuilt.
1143
1144 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
1145 PLUGIN/guile.libs. configure generates the latter from the former.
1146 * Makefile.in: Rebuilt.
1147
1148 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
1149 need this if we install scripts, like guile-snarf.
1150 * configure: Rebuilt.
1151
1152 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1153
1154 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
1155
1156 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
1157
1158 * socket.c (scm_addr_vector): fix faulty scm_listify.
1159
1160 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
1161
1162 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
1163 style block comment is no longer considered an error.
1164
1165 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
1166
1167 * PLUGIN/guile.libs.in: New file.
1168 * PLUGIN/guile.libs: Removed from repository.
1169 * configure.in: Create PLUGIN/guile.libs from
1170 PLUGIN/guile.libs.in. This is for including additonal libraries
1171 needed for dynamic linking.
1172 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
1173 instead of PLUGIN/guile.libs.
1174
1175 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
1176
1177 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
1178
1179 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
1180 occurrences of the given element from the list, not just the
1181 first. This is how the Emacs Lisp functions behave, how the
1182 analogous Common Lisp functions behave, and (I believe) how the
1183 older Maclisp functions worked. I realize that this change may
1184 break code, but it seemed better to break it before the Guile
1185 release than after.
1186
1187 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
1188 Their prototypes were already present in gc.h, but they weren't
1189 implemented.
1190 (scm_init_storage): Initialize scm_protects.
1191 * root.c (scm_protects): New element of scm_sys_protects.
1192
1193 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
1194
1195 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1196
1197 * libguile.h: Added #include "libguile/net_db.h".
1198
1199 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
1200 30 change. That file is only meant for communication between the
1201 configuration process and load.c. If code linked against libguile
1202 wants to get at the paths mentioned in libpath.h, it can call
1203 functions declared in load.h.
1204
1205 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1206
1207 * libguile.h: Removed #include "libguile/fdsocket.h"
1208
1209 * net_db.c: Added #include <sys/socket.h>.
1210
1211 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
1212
1213 * filesys.c (scm_input_waiting_p): use select in preference to
1214 FIONREAD, since the latter doesn't detect EOF.
1215 Throw error if neither select nor FIONREAD available.
1216
1217 * socket.c (scm_connect): take a port, not a fd object.
1218 (scm_fill_sockaddr): throw an error if fam is not recognised.
1219 (scm_bind): use scm_fill_sockaddr.
1220 (scm_listen): take a port, not a fd object.
1221 (scm_accept): take and return a port. return #f in the car if
1222 address can't be got
1223 (scm_sock_fd_to_port): new procedure.
1224 (scm_socket): use scm_sock_fd_to_port.
1225 (scm_addr_vector): throw error if unrecognised address type.
1226 take an extra argument with the calling procedure name.
1227 (scm_getsockname): take a port. return #f if address can't be got.
1228 (scm_getpeername): take a port. return #f if address can't be got.
1229 (scm_recvfrom): take a port. return #f for address component if can't
1230 be got.
1231 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
1232 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
1233
1234 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
1235
1236 * throw.c (scm_internal_catch): Make body funcs and handler funcs
1237 use separate data pointers, to allow them to be designed
1238 independently and reused.
1239 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
1240 Renamed from catch_body, catch_handler, and uncaught_throw; made
1241 generically useful.
1242 (struct scm_catch_body_data): Renamed from catch_body_data; moved
1243 to throw.h.
1244 (scm_catch): Use the above.
1245 (scm_throw): Don't bother printing a message for an uncaught
1246 throw; we establish a default handler in init.
1247 * throw.h (scm_internal_catch): Prototype updated.
1248 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
1249 decls.
1250 (struct scm_body_thunk_data): New structure, used as data
1251 argument to scm_body_thunk.
1252 * init.c (struct main_func_closure): New structure, packaging up
1253 the data to pass to the user's main function.
1254 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
1255 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
1256 scm_internal_catch to establish a catch-all handler, using
1257 scm_handle_by_message. This replaces the special-case code in
1258 scm_throw.
1259 (invoke_main_func): Body function for scm_internal_catch; invoke
1260 the user's main function, using the main_func_closure pointer to
1261 decide what to pass it.
1262 * root.c (struct cwdr_body_data): Remove handler_proc member.
1263 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
1264 (cwdr_handler): Removed.
1265
1266 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1267
1268 * socket.h (SCM_P): update bind prototype.
1269 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
1270 include "feature.h".
1271 (scm_socket): return a port, not a file descriptor object.
1272 include "fports.h" and <unistd.h>
1273 (scm_bind): take a port, not a file descriptor object.
1274 take an extra argument for address args.
1275
1276 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
1277 INADDR_NONE, INADDR_LOOPBACK.
1278
1279 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1280
1281 * init.c: include net_db.h and not fdsocket.h.
1282 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
1283
1284 * Makefile.am: corresponding changes.
1285 * socket.h: renamed from fdsocket.h, fix names.
1286 * net_db.h: renamed from socket.h, fix names.
1287 * socket.c: renamed from fdsocket.c.
1288 remove _sys from procedure names.
1289 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
1290 add "socket" to features list.
1291 * net_db.c: renamed from socket.c.
1292 remove _sys from procedure names.
1293 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
1294 add "net-db" to features list.
1295 include "net_db.h". don't include <sys/socket.h> or
1296 <sys/un.h>.
1297
1298 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1299
1300 * tags.h (scm_tags): Removed comma at end of last enumerator.
1301
1302 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
1303
1304 Don't use GCC extensions to allocate space for debugging frames.
1305 (Here he goes again! Why do we put up with this?!)
1306 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
1307 an scm_debug_info structure, not an in-line array of them. Add
1308 'info' member, to say how many vect elements we've used, for eval
1309 frames.
1310 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
1311 a new variable debug_info_end to mark the end of vect, instead of
1312 the address of the 'info' pointer itself.
1313 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
1314 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
1315 (SCM_APPLY): Explicitly allocate space for debug.vect.
1316 * debug.c (scm_m_start_stack): Same, for vframe.vect.
1317 * stacks.c: Adjusted for new debug frame structure.
1318 (RELOC_INFO, RELOC_FRAME): New macros.
1319 (stack_depth, read_frames): Use them, and new scm_debug_frame
1320 element 'info', instead of magically knowing that eval frames have
1321 an info pointer sitting after vect.
1322 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
1323 RELOC_FRAME.
1324 (scm_init_stacks): Formatting tweaks.
1325
1326 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
1327
1328 Give GCC more control flow information, so it can be sure that
1329 variables aren't used uninitialized.
1330 * error.h (scm_error, scm_syserror, scm_syserror_msg,
1331 scm_sysmissing, scm_num_overflow, scm_out_of_range,
1332 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
1333 scm_misc_error): Tell GCC that these functions never return.
1334 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
1335 out the field type, call abort if SCM_ASSERT returns, to placate
1336 the optimizer.
1337 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
1338 scm_wta ever returns. We can't handle this case anyway, and this
1339 gives the optimizer more information.
1340 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
1341 scm_wta ever returns.
1342
1343 In some cases, the code is fine, but GCC isn't smart enough to
1344 figure that out; this usually happens when one variable is only
1345 initialized and used when a particular condition holds true, and
1346 we know that condition will never change within a given invocation
1347 of the function. In this case, we simply initialize the variables
1348 to placate the compiler, hopefully to a value which will cause a
1349 crash if it is ever actually used.
1350 * print.c (scm_iprin1): Initialize mw_pos.
1351 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
1352 * throw.c (scm_ithrow): Initialize dynpair.
1353 * unif.c (scm_uniform_vector_ref): Initialize cra.
1354 * struct.c (init_struct): Initialize prot.
1355 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1356
1357 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1358 if EXPR contains no expressions.
1359
1360 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1361
1362 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1363 cause an infinite loop (???). So much for the algebraic
1364 equivalency of variable-sized arrays and alloca...
1365
1366 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1367
1368 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1369 a SCM boolean, not a C boolean.
1370
1371 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1372
1373 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1374 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1375 rules for raising scm_mtrigger. Previously, unfortunate but not
1376 unlikely circumstances could result in almost constant invokation
1377 of the gc. Now, this situations should be less likely, but they
1378 are not prevented completely.
1379
1380 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1381
1382 * numbers.c (scm_fuck): Procedure removed; looks like old test
1383 code.
1384 * numbers.h: Prototype removed.
1385
1386 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1387
1388 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1389 array to a pointer, to match my Nov 21 change in eval.c.
1390
1391 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1392
1393 * libguile.h: Added #include "libguile/backtrace.h", #include
1394 "libguile/stacks.h".
1395
1396 * strings.c (scm_string scm_make_string scm_string_ref
1397 scm_string_set_x scm_string_equal_p scm_string_append):
1398 Bugfix according to scm patch from Aubrey Jaffer:
1399 Corrected long-standing
1400 (not (eqv? (integer->char 128)
1401 (string-ref (make-string 1 (integer->char 128)) 0)))
1402 bug found by John Kozak <jk@noontide.demon.co.uk>.
1403
1404 * strports.c, strports.h: Make scm_eval_0str return the value of
1405 the last expression evaluated (previously, it returned void).
1406
1407 * strports.c, strports.h: New function: scm_read_0str. Does what
1408 it sounds like.
1409
1410 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1411
1412 * simpos.c (scm_getenv): return #f if string can't be found in the
1413 environment instead of throwing an exception, for compatibility
1414 with numerous other systems.
1415
1416 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1417
1418 * Makefile.am (.c.x): Use guile-snarf.
1419 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1420 executable.
1421 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1422
1423 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1424
1425 * backtrace.c (scm_display_error_message): Made non-static, and
1426 renamed from display_error_message.
1427 * backtrace.h (scm_display_error_message): Added extern decl.
1428 * throw.c (uncaught_throw): Use it to display the error message.
1429
1430 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1431
1432 * inet_aton.c: Use #if 0, not #ifdef 0.
1433
1434 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1435
1436 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1437 to convert the returned value.
1438 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1439 the offset argument.
1440
1441 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1442
1443 Add new interface to catch/throw, usable from C as well as
1444 Scheme.
1445 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1446 (scm_internal_catch): New function, replaces...
1447 (scm_catch_apply): Deleted.
1448 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1449 mechanism which is a bit more code, but can be used nicely from C
1450 and implement the Scheme semantics as well.
1451 (scm_internal_catch): This is the replacement; it's named after
1452 the analogous function in Emacs.
1453 (scm_catch): Reimplemented in terms of the above.
1454 (struct catch_body_data, catch_body, catch_handler): New
1455 functions, used by scm_catch.
1456 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1457 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1458 support for new cwdr.
1459
1460 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1461 Oct 30.
1462
1463 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1464
1465 * acconfig.h: Added DYNAMIC_LINKING symbol.
1466 * configure.in: Add option and checks for dynamic linking.
1467 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1468 dynl.h: New files for dynamic linking support.
1469 * Makefile.am (libguile_a_SOURCES):
1470 Added "dynl.c".
1471 (modinclude_HEADERS): Added "dynl.h".
1472 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1473 "dynl-vms.c".
1474 * init.c (scm_boot_guile_1): Call
1475 scm_init_dynamic_linking to initialize dynamic linking support.
1476
1477 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1478
1479 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1480 (as we Schemers say). It needs to be global, so that I can tweak
1481 it for the proper operation of unexec.
1482 (scm_boot_guile_1_live): New variable, see above.
1483
1484 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1485
1486 * guile-snarf.sh: Removed.
1487 * PLUGIN/guile.libs: Added dependency for -lm.
1488 * acinclude.m4: Renamed from aclocal.m4.
1489 * PLUGIN/greet: Removed.
1490 * Makefile.am, aclocal.m4: New files.
1491 * configure.in: Updated for Automake.
1492
1493 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1494
1495 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1496 and not top_level_lookup_thunk_var.
1497
1498 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1499
1500 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1501
1502 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1503
1504 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1505 Scheme function, instead of syntax. Single argument is now a
1506 symbol.
1507
1508 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1509
1510 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1511 scm_ra_divide): Properly terminate statements passed as arguments
1512 to IVDEP macros. (Thanks to Bernard Urban.)
1513
1514 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1515 with non-constant sizes. (Thanks to Bernard Urban.)
1516
1517 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1518
1519 It's an "eval closure", not an "eval thunk." A thunk is a
1520 function of no arguments.
1521 * root.h (struct scm_root_state): Renamed
1522 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1523 (scm_top_level_lookup_closure_var): Renamed from
1524 scm_top_level_lookup_thunk_var.
1525 * root.c (mark_root): Uses changed.
1526 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1527 * init.c (scm_start_stack): Uses changed.
1528 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1529 Change scheme-visible name to *top-level-lookup-closure* from
1530 *top-level-lookup-thunk*.
1531
1532 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1533
1534 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1535 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1536
1537 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1538
1539 * gc.c (struct scm_heap_seg_data): Doc fixes.
1540
1541 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1542 sweeping. Then, prepend each segment's free cells to its
1543 freelist, rather than wiping out the old value. (Thanks to Marius
1544 Vollmer.)
1545
1546 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1547 scm_check_freelist, scm_debug_newcell): New functions and
1548 variables, for debugging freelist problems.
1549 * pairs.h (SCM_NEWCELL): New debugging version added.
1550 * gc.h (scm_debug_newcell): Added extern declaration, used by
1551 debugging version of SCM_NEWCELL.
1552
1553 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1554
1555 On some systems <libc.h> conflicts with <unistd.h>, and should not
1556 be #included at all.
1557 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1558 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1559 * configure.in: Call it.
1560 * posix.c, filesys.c: Use its results to decide whether or not to
1561 #include <libc.h>.
1562 * configure, scmconfig.h.in: Rebuilt with autoconf and
1563 autoheader.
1564
1565 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1566
1567 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1568 pointer to the stdio stream before calling scm_setbuf0, so the
1569 latter will be able to retrieve it. I'm surprised this didn't
1570 segfault earlier. (Thanks to Christopher Lee.)
1571
1572 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1573
1574 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1575 of `lazy-catch'.
1576
1577 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1578
1579 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1580 number of stack narrowing specifier pairs. The first specifier in
1581 a pair controls inner border, the second the outer border. A
1582 number means cut that number of frames, a procedure object means
1583 cut until that object is found in operator position in a frame.
1584
1585 * root.c (cwdr): Bugfix.
1586
1587 * read.c: Recording of positions disabled by default.
1588
1589 * procs.c (scm_closure_p): New function.
1590
1591 * posix.c (scm_tmpnam): New function.
1592
1593 * load.c: Added #include "throw.h".
1594 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1595 ends with '/'.
1596
1597 * load.c, load.h (scm_read_and_eval_x): New function.
1598
1599 * eval.c: Renamed debug option "deval" to "debug".
1600
1601 (scm_eval_x): `eval!' is no longer accessible from the scheme
1602 level. Motivation: We can't allow operations which introduce
1603 glocs into the scheme level. Guile's type system can't handle
1604 these as data. Use `eval' or `read-and-eval!' as replacement.
1605
1606 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1607 SCM_CONSP since this is a macro!; Set vframe.prev to
1608 scm_last_debug_frame instead of 0. In this way we can look
1609 "above" the virtual start stack frame if we wish.
1610 (scm_debug_hang): New function: Useful for debugging Guile in
1611 certain tricky situations. Will probably be removed later...
1612
1613 * debug.h: Changed semantics of debug option "backtrace". This
1614 option now only indicates whether we want automatic backtrace at
1615 an error.
1616
1617 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1618
1619 * ports.c: #include "filesys.h"
1620 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1621
1622 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1623 Motivation: This is system specific code which is related to file
1624 I/O. It also may use select. Added code by Gary Houston to
1625 detect presence of character in stdio buffers.
1626
1627 * libguile.h: #include "libguile/libpath.h"
1628
1629 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1630 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1631 SCM_SITE_DIR; Install libpath.h among the other include files.
1632
1633 * load.c, load.h (scm_sys_package_data_dir): New function.
1634
1635 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1636
1637 * stacks.h: Bugfix: Don't use tail-array length field as stack
1638 length field! This screwed GC.
1639
1640 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1641
1642 * _scm.h: Added #ifndef around definition of macros min and max.
1643
1644 * __scm.h: Added hooks for threads to plugin to in ints protection
1645 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1646 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1647 the main code in these macros duplicated and spread over multiple
1648 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1649 SCM_THREAD_SWITCHING_CODE.
1650
1651 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1652
1653 * snarf.h: New file.
1654 * guile-snarf.sh: New file.
1655 * Makefile.in (inner_h_files): Added snarf.h
1656 (ancillary, install, uninstall, distclean): Added actions for
1657 guile-snarf.
1658 (.c.x): Use guile-snarf.
1659 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1660 (gen_c_files): Note that these depend on guile-snarf.
1661 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1662 now in "snarf.h". Added #include "snarf.h" to get them.
1663 * libguile.h: Added #include "snarf.h".
1664 (Patches applied and tweaked by Jim Blandy.)
1665
1666 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1667
1668 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1669 standards suggest against providing prototypes for system
1670 functions. Thanks to Greg Troxel.
1671
1672 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1673
1674 * strports.c (scm_eval_0str): New function.
1675 #include "read.h", to get prototype for scm_read.
1676 * Makefile.in (strports.o): Update dependencies.
1677 * strports.h: New prototype.
1678
1679 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1680 scheme name from "int?" to "integer?". It seems to do the job.
1681 * numbers.h: Rename prototype too.
1682 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1683 hope this is right.
1684
1685 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1686 scm_num_eq_p): Rename these according to R4RS conventions: call
1687 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1688 to making libguile R4RS compliant without ice-9...
1689
1690 * load.c (scm_sys_search_load_path): Search for files under all
1691 extensions listed in the %load-extensions variable. If FILENAME
1692 is absolute, return it unchanged, without searching the load path.
1693 (scm_loc_load_extensions): New variable, pointing to
1694 %load-extensions' value cell.
1695 (scm_init_load): Initialize it, and the value it points to.
1696 (scm_primitive_load_path): Improve error reporting.
1697
1698 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1699 of new Scheme variable %load-hook.
1700 (scm_primitive_load): Apply %load-hook to filename.
1701
1702 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1703
1704 * configure.in: add tests for figuring out whether buffered data
1705 is available in a FILE structure, which is needed by char-ready.
1706
1707 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1708 FILE_CNT_READPTR.
1709
1710 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1711 exceptions using misc_error instead of syserror. It seems a bit
1712 odd to throw an exception if a string can't be found in the
1713 environment, but it's consistent with open-file, stat etc.
1714 (simpos.h): remove sys_ from getenv.
1715
1716 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1717 occurs, throw an error instead of returning errno. Return value
1718 is now unspecified.
1719 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1720
1721 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1722
1723 * filesys.c (scm_stat2scm): derive file type and permissions from
1724 the stat mode and append them to the returned vector.
1725 There isn't much overhead in doing this and it avoids the need to
1726 work with S_IRUSR et al. in Scheme.
1727 Define symbols scm_sym_regular etc.
1728 (scm_init_filesys): don't intern S_IRUSR etc.
1729
1730 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1731 and s_primitive_load_path.
1732
1733 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1734
1735 * error.h: don't declare error symbols. prototype for scm_misc_error.
1736
1737 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1738 error.c.
1739
1740 * error.c: use SCM_SYMBOL to set up error keys.
1741 scm_misc_error: new procedure.
1742
1743 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1744
1745 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1746 between `#!' and `!#' is ignored.
1747 (skip_scsh_block_comment): New function.
1748
1749 * feature.c (scm_set_program_arguments): New argument, FIRST.
1750 * feature.h: Update prototype.
1751 * init.c (scm_boot_guile_1): Pass new argument to
1752 scm_set_program_arguments.
1753
1754 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1755
1756 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1757 (scm_boot_guile): Call scm_set_program_arguments here, later than
1758 the old initialization.
1759
1760 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1761 initialization procedure.
1762 - Delete in, out, err arguments; there are other perfectly good
1763 ways to override these when desired.
1764 - Delete result argument; this function shouldn't ever return.
1765 - Rename init_func argument to main_func, for less confusion.
1766 - Delete boot_cmd argument; main_func is more general.
1767 -Add 'closure' argument, to help people pass data to main_func
1768 without resorting to global variables.
1769 - Abort if reentered; don't bother returning an error code.
1770 - Call scm_init_standard_ports to set up the default/current
1771 standard ports; no need to pass them to scm_start_stack.
1772 - Remove code to evaluate the boot_cmd, and start the repl; let
1773 the user do something like that in main_func if they want.
1774 - Remove code to package up a return value; main_func can do any
1775 of that as needed.
1776 - Call exit (0), instead of returning.
1777 (scm_start_stack): Don't initialize the I/O ports here; that's
1778 weird. Delete in, out, err arguments. Move guts to
1779 scm_init_standard_ports, scm_stdio_to_port.
1780 (scm_init_standard_ports): New function, to set up current and
1781 default standard ports.
1782 (scm_start_stack, scm_restart_stack): Make these static.
1783 * init.h (scm_boot_guile): Adjust declaration.
1784 (scm_start_stack, scm_restart_stack): Remove externally
1785 visible declarations for these.
1786 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1787
1788 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1789 written out several times in scm_start_stack.
1790 * fports.h: New declaration for the above.
1791
1792 * feature.c (scm_set_program_arguments): New function.
1793 * feature.h: New declaration for the above.
1794
1795 * ports.c: Formatting tweak.
1796
1797 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1798
1799 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1800 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1801 for obtaining the address of a car or cdr field. Motivation:
1802 &SCM_CXR make assumptions about the internal structure of the
1803 SCM_CXR selectors.
1804
1805 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1806 Motivation: see SCM_CXRLOC.
1807
1808 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1809 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1810 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1811 Motivation: Safer use. Some other macros are defined in terms of
1812 these operations. If these are defined using the SCM_SETCXR
1813 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1814 to inefficiency and an <e1> with side-effects could potentially
1815 break. Also, these particular operations are heavily utilized in
1816 the garbage collector. In unoptimized code there will be a
1817 measurable speedup.
1818
1819 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1820 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1821 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1822 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1823 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1824 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1825 vports.c: Cleaned up use of pairs: Don't make any special
1826 assumptions about the internal structure of selectors and
1827 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1828 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1829 (Among other things, this change makes it easier to build Guile
1830 with certain compilers which have problems with casted lvalues.)
1831
1832 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1833
1834 * stacks.c: Improve selection of relevant stack frames when making
1835 a stack object. Introduce one level of indirection in the stack
1836 object to make it possible to "narrow" to a certain region of the
1837 stack. This facilitates making use of more clever algorithms (not
1838 implemented) for selecting relevant frames and gives a cleaner
1839 design since selection of frames can be done independently of
1840 extraction of frames from the real stack.
1841 (scm_stack_id): Also take #t as argument which means look at
1842 current stack.
1843
1844 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1845 Turn n_tail into an integer directly representing current number
1846 of frames in stack. Add field tail.
1847
1848 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1849
1850 * debug.c (scm_make_memoized): Made it available at scheme level.
1851 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1852 SCM_NIMP before applying heavier predicates in argument checking.
1853 (scm_local_eval): Also take memoized object as argument.
1854
1855 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1856 aren't created with zero length, but should such a strange
1857 creature suddenly turn up...
1858
1859 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1860
1861 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1862 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1863
1864 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1865
1866 * variable.c (scm_make_variable): Make the name hint optional, as
1867 documented.
1868 (anonymous_variable_sym): Renamed from variable_sym. All uses
1869 changed.
1870
1871 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1872 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1873 of scm_primitive_load_path was also changed to
1874 "primitive-load-path", from "%try-load-path". Callers changed.
1875 We'd like to respect the convention that a function named
1876 "try-mumble" should behave just like the function called "mumble",
1877 but return #f instead of signalling some error.
1878 * load.h: Rename prototypes.
1879
1880 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1881
1882 * print.c (make_print_state, grow_print_state), print.h: Modified
1883 the print state representation: Don't use a tail array for
1884 recording of circular references. Resizing of the print state
1885 structure invalidates the print state pointer. To avoid passing
1886 around an indirect print state reference to all printing
1887 functions, we instead let the print state reference a resizable
1888 vector.
1889
1890 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1891
1892 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1893 Don't crash when passed an improper list terminated by a
1894 non-immediate value.
1895
1896 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1897
1898 Allocate data for structures on an eight-byte boundary, as
1899 required by the tagging system.
1900 * struct.c (alloc_struct): New function.
1901 (scm_make_struct, scm_make_vtable_vtable): Call it.
1902 * struct.h (scm_struct_n_extra_words): Bump to 3.
1903 (scm_struct_i_ptr): New "field".
1904 * gc.c (scm_gc_sweep): When we need to free the data, use the
1905 information stored by alloc_struct to find the beginning of the
1906 block allocated to the structure, so we can free it.
1907
1908 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1909
1910 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1911 scm_init_stacks.
1912
1913 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1914 (scm_debug_info): New member: id.
1915
1916 * stacks.c: Stacks are now represented as structs; Stacks have an
1917 id given to them by `start-stack'.
1918 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1919
1920 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1921 Changed stack representation.
1922
1923 * debug.c (scm_procedure_name): Try procedure property `name' for
1924 compiled closures aswell.
1925
1926 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1927
1928 * eval.c: scm_i_name moved to gsubr.c
1929 (scm_m_define): Record names of all kinds of procedure
1930 objects. (Earlier, only closures were recorded.)
1931
1932 * procprop.h: Added declaration of scm_i_name.
1933
1934 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1935 (scm_make_gsubr): Record names of compiled closures.
1936
1937 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1938
1939 * debug.c, debug.h: Removed obsolete code.
1940
1941 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1942 stacks.c: Renamed regs --> scm_contregs.
1943
1944 * print.c (scm_free_print_state): Cleanup print state before
1945 returning it to pool. It is better to do it here than in
1946 scm_prin1 since scm_prin1 is called often.
1947
1948 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1949 s_set_source_property_x): Check that first argument is a pair or a
1950 memoized object.
1951
1952 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1953 scm_i_line, scm_i_column and scm_i_breakpoint global.
1954
1955 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1956 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1957 scm_init_stacks.
1958
1959 * debug.h: Added debug object smob declaration and macro
1960 definitions.
1961
1962 * configure.in: Build with backtrace.o and stacks.o if debug
1963 support enabled.
1964
1965 * Makefile.in: Added entries for new files: backtrace.c,
1966 backtrace.h, stacks.c and stacks.h.
1967
1968 * symbols.c (scm_sym2ovcell): Fixed documentation.
1969
1970 * _scm.h (min, max): Added.
1971
1972 * async.c: Moved `min' macro to _scm.h.
1973
1974 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1975 SCM_BACKTRACE_INDENT.
1976
1977 * eval.c: Added new debug options `maxdepth' and `indent'.
1978
1979 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1980
1981 * print.h: Added selector SCM_PRINT_STATE.
1982
1983 * print.c: New functions: scm_make_print_state,
1984 scm_free_print_state.
1985
1986 * print.h: Added declarations for scm_make_print_state,
1987 scm_free_print_state.
1988
1989 * debug.c (scm_m_start_stack): New acro.
1990
1991 * debug.h: Small cleanup.
1992
1993 * init.c (scm_boot_guile_1): Moved scm_init_debug below
1994 scm_init_eval.
1995
1996 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1997
1998 * __scm.h, alist.c, alist.h, append.c, append.h, appinit.c,

2016 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
2017 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
2018 declare functions with prototypes. (Patch thanks to Marius
2019 Vollmer.)
2020
2021 More prototype-related changes from Marius Vollmer:
2022 * gdb_interface.h: Wrapped header file in #ifdef/#endif
2023 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
2024 * ports.h (ptobfuns): Added prototypes. This means some casting in
2025 fports.c.
2026 * fports.c: Added casts for initializations, since the functions
2027 are defined to take FILE * as their stream argument, not SCM.
2028 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
2029 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
2030 to `char *str_data' to conform to prototype.
2031
2032 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2033
2034 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
2035
2036 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
2037
2038 * stime.c, stime.h: use SCM_P method.
2039
2040 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2041
2042 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
2043 be given at least two arguments. Insist that lst's last element
2044 be a list, but don't make any requirements of its predecessors.
2045
2046 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2047
2048 * eval.c (scm_nconc2last): Revert last change; there seems to be
2049 other stuff going on here.
2050
2051 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2052
2053 * eval.c (scm_nconc2last): Make sure that each element of lst
2054 (which is a list of argument lists, except for the tail) is a
2055 proper list, i.e., finite and terminated by '().
2056
2057 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2058
2059 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
2060 Clarifies flow.
2061
2062 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
2063 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
2064 saying "1".
2065
2066 * vectors.c (scm_make_vector): Fill vectors with the undefined
2067 value, to help make Guile Scheme code more portable to other
2068 Schemes.
2069
2070 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
2071 * symbols.h, tags.h: Doc fixes.
2072
2073 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
2074
2075 * async.c (scm_take_signal): Doc fixes.
2076
2077 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
2078
2079 * numbers.c (scm_divbigint): When the remainder is zero, we don't
2080 want to subtract it from the modulus; we just want to leave it
2081 alone.
2082
2083 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
2084
2085 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
2086 `scm_init_threads'.
2087
2088 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
2089
2090 * throw.c (scm_catch_apply): Finished implementation of
2091 `lazy-catch'.
2092
2093 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2094
2095 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
2096 check.
2097 (scm_init_filesys): set "i/o-extensions" feature.
2098 include feature.h.
2099
2100 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
2101
2102 * Makefile.in (root.o): Correct dependencies.
2103
2104 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
2105
2106 * Makefile.in: Added dependency entry for root.o.
2107
2108 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
2109 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
2110
2111 * init.c (scm_start_stack): Set initial root continuation number
2112 to 0.
2113
2114 * procs.c: New function: scm_thunk_p.
2115
2116 * procs.h: Added declarations of scm_thunk_p.
2117
2118 * root.c: Renamed `call-with-new-root' -->
2119 `call-with-dynamic-root'.
2120 (cwdr): Removed allocation of new root state. This should be done
2121 separately by use of scm_make_root.
2122 (scm_apply_with_dynamic_root): New function: Does what it
2123 sounds like. Needed when spawning threads.
2124
2125 * root.h: Added member last_debug_frame to root state.
2126 Added #include "libguile/debug.h"
2127
2128 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
2129 arguments. The motivation is that code in root.c needs catch
2130 functionality, and we want to avoid code duplication.
2131 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2132 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2133 handlers that run without popping the stack into the dynwind
2134 chain.
2135
2136 * throw.h: Added prototypes for scm_catch_apply and
2137 scm_lazy_catch.
2138
2139 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2140
2141 * root.h (scm_root, scm_set_root): Decouple thread support details
2142 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2143 SCM_SET_THREAD_LOCAL_DATA.
2144
2145 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2146 and tortoise scanning loop.
2147
2148 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2149
2150 * Makefile.in: Rebuild dependencies.
2151
2152 * libguile.h: #include "libguile/print.h" before "smob.h", since
2153 the latter uses the print_state structure.
2154
2155 * throw.c (scm_ithrow): Use the correct variable when checking to
2156 see if a given element of scm_dynwinds is a valid catch.
2157
2158 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2159 structure, abort; don't just silently ignore the garbage.
2160
2161 * _scm.h: #include "print.h" here, since it seems to be used just
2162 about everywhere.
2163 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2164 strports.c, unif.h: Don't #include "print.h".
2165
2166 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2167
2168 * feature.h (scm_loc_features): Removed external declaration.
2169 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2170
2171 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2172
2173 * feature.c (scm_init_feature): Added threads feature (needs to be
2174 initialized here, since features doesn't exist when
2175 scm_init_threads is called).
2176
2177 * libguile.h: Added #include "libguile/../threads/threads.h".
2178 (This is a kludge to get thread support working. This should be
2179 fixed.)
2180
2181 * configure.in, acconfig.h: Added flags for thread support.
2182
2183 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2184 mit-pthreads.
2185
2186 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2187 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2188 root.c:mark_root.
2189
2190 * _scm.h: Added conditional #include "threads.h"
2191
2192 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2193 SCM_THREADS_SWITCHING_CODE.
2194
2195 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2196 allocate the basic dynamic root object.
2197 (scm_boot_guile): Added call to scm_init_root.
2198
2199 * root.c, root.h: Added root smob.
2200 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2201 functions: Implements dynamic roots mostly according to spec in
2202 SCM manual. Main difference is that the second argument is a
2203 throw handler rather than an error "thunk".
2204
2205 * root.h: Added declaration of scm_init_root.
2206
2207 * root.c: Added #include "genio.h", #include "smob.h", #include
2208 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2209 "eval.h"
2210 (scm_init_root): Added #include "root.x".
2211
2212 * throw.c: Added #include "stackchk.h"
2213 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2214 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2215 can be used in scm_call_with_new_root; Added reenabling of stack
2216 checking when catching a throw.
2217
2218 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2219
2220 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2221
2222 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2223 element is not found, as per R4RS.
2224
2225 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2226
2227 * list.c: Doc fixes throughout.
2228
2229 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2230
2231 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2232 declare the char * to be const. Avoids a warning in rgx.c.
2233
2234 * ports.h: spelling fix.
2235
2236 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2237 error messages.
2238
2239 * load.c (scm_sys_try_load_path): throw an error if file not found
2240 (like it says it in NEWS).
2241
2242 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2243
2244 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2245 PROPS slot to '(), not #f; it's an empty alist.
2246
2247 * throw.h, throw.c: Use SCM_P instead of #if hair.
2248
2249 Remove special support for uncaught throws; see throw.c for
2250 rationale.
2251 * throw.c (uncaught_throw): New function.
2252 (scm_ithrow): Call uncaught_throw if we don't find a throw
2253 target; don't mess with scm_bad_throw_vcell.
2254 (scm_bad_throw_vcell): Variable deleted.
2255 (scm_init_throw): Don't initialize it.
2256
2257 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2258 #t catches.
2259
2260 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2261
2262 * numbers.c (scm_istr2int): If the number is short (as most
2263 numbers are), just call scm_small_istr2int to deal with it.
2264 (scm_small_istr2int): New function, created by un-#ifdefing the
2265 non-bignum version of scm_istr2int and renaming it.
2266
2267 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2268
2269 * load.c (scm_sys_try_load): don't check whether value returned
2270 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2271 Change the Scheme name from %try-load to primitive-load.
2272
2273 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2274 Can avoid passing a message, allowing it to be derived in the
2275 error handler (e.g., if we want to throw to the key both from
2276 Scheme and C).
2277
2278 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2279
2280 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2281 references now have a new appearance which is more compact and
2282 also gives a clue about what the target of the reference is.
2283 By setting parameters in the print state, more fancy printing can
2284 be achieved. This is used by the (not yet commited) backtrace
2285 code.
2286
2287 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2288
2289 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2290 "print.h"
2291
2292 * print.c: Added #include "struct.h". Removed function
2293 scm_prlist.
2294
2295 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2296 scm_iprin1. Removed prototype for scm_prlist.
2297
2298 * arbiters.c (prinarb),
2299 async.c (print_async),
2300 debug.c (prindebugobj, prinmemoized),
2301 eval.c (prinprom, prinmacro),
2302 filesys.c (scm_fd_print, scm_dir_print),
2303 kw.c (print_kw),
2304 mallocs.c (prinmalloc),
2305 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2306 smob.h (scm_smobfuns),
2307 srcprop.c (prinsrcprops),
2308 throw.c (prinjb),
2309 unif.c, unif.h (scm_raprin1, rapr1),
2310 variable.c (prin_var): Changed argument `int writing' to
2311 `scm_print_state *pstate'.
2312
2313 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2314 that it will be called before scm_init_print.
2315
2316 * print.c (scm_prin1): Print states are now allocated when calling
2317 scm_prin1 and then passed around to all printing functions as an
2318 argument. A cache `print_state_pool' enables reuse of print
2319 states.
2320 (scm_make_print_state): New function.
2321 (scm_iprin1): Adaption to print states.
2322 (scm_iprlist): An initial "hare and tortoise" scan brings down
2323 time complexity to O (depth * N). (Better time complexity will be
2324 achieved when the printing code is completely rewritten.)
2325
2326 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2327
2328 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
2329 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
2330 it gets done whether or not the cache variable has a value.
2331
2332 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2333
2334 Distinguish #f and ().
2335 * __scm.h: #undef SICP.
2336 * pairs.h (SCM_EOL): Delete this definition, equating it with
2337 SCM_BOOL_F.
2338 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2339 the value it used to have. Doc fixes, too.
2340
2341 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2342
2343 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2344 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2345 Lord's implementation of structs, allowing for tail arrays as
2346 described in the manual. Also fixed some bugs. (Both the interface
2347 and the implementation should be improved.)
2348
2349 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2350
2351 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2352 People who whish to see the source can do `(print-enable 'source)'.
2353 Removed #ifdef DEBUG_EXTENSIONS.
2354
2355 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2356
2357 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2358 integer (assuming for now accepting an integer is a good thing).
2359
2360 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2361 %S will be used instead for write'ing arguments.
2362
2363 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2364 asserts. fix a few other asserts.
2365 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2366 scm_uniform_vector_ref, scm_array_set_x,
2367 scm_dimensions_to_unform_array): change args in
2368 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2369 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2370 scm_substring_fill_x): likewise.
2371 gsubr.c (scm_gsubr_apply): likewise.
2372 eval.c (SCM_APPLY): likewise.
2373
2374 * eval.c (4 places): replace scm_everr with lgh_error or
2375 scm_wrong_num_args.
2376
2377 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2378 scm_memory_error): new procedures.
2379 scm_everr: deleted. can use scm_wta, dropping first two args.
2380 scm_error: convert NULL subr to SCM_BOOL_F.
2381
2382 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2383 SCM_ARGERR.
2384
2385 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2386 of scm_wta.
2387
2388 * error.c, error.h: new error keys: scm_arg_type_key,
2389 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2390 scm_misc_error_key.
2391 scm_wta: reimplement using lgh_error instead of scm_everr.
2392
2393 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2394
2395 * gdbint.c: scm_lread now has one more argument.
2396
2397 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2398 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2399 loading source from non-file ports, which, e. g., happens when
2400 using the Emacs interface).
2401
2402 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2403 object.
2404
2405 * read.c: Added code for recording of positions of source code
2406 expressions; New functions: recsexpr, scm_lreadrecparen;
2407 _scm_make_srcprops --> scm_make_srcprops
2408 (scm_flush_ws): Removed updating of positions counters. This work
2409 is already done by scm_gen_getc
2410
2411 * read.h: Added prototype for scm_lreadrecparen
2412
2413 * print.c: Added #include "alist.h"
2414
2415 * eval.c: Added #include "hash.h"
2416
2417 * eq.c: Added #include "ramap.h"
2418
2419 * options.c: Documentation fixes.
2420
2421 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
2422 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2423 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2424 --> scm_make_srcprops
2425
2426 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2427 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2428 function calls in the definition of the whash access macros.
2429
2430 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2431
2432 * init.c (scm_boot_guile): Add level of indirection to
2433 scm_boot_guile_1() to ensure that stack base pointer is properly
2434 initialized. There was no guarantee that variable i was the
2435 highest/lowest variable on stack (i.e. the call frame of
2436 scm_boot_guile was not completely protected from gc).
2437
2438 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2439
2440 * ports.h (scm_port_table): put back file_name, it will be used to
2441 support debugging. Undo related changes in fports.c, ioext.c,
2442 ports.c, gc.c.
2443
2444 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2445
2446 * ports.h (scm_port_table): remove file_name member for now, it seems
2447 undesirable.
2448 * fports.c (scm_open_file): don't set file_name in PTAB.
2449 (prinfport): don't use file_name in PTAB.
2450 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2451 * ports.c (scm_add_to_port_table): don't intialize file_name.
2452 (scm_port_file_name): remove for now.
2453 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2454
2455 * fports.h (scm_mkfile): prototype deleted.
2456 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2457
2458 * debug.c, unif.c: use scm_out_of_range instead of
2459 wta for range errors (ASSERT still needs work).
2460
2461 * error.c, error.h (scm_out_of_range): new procedure.
2462
2463 * error.c, error.h (scm_out_of_range_key): new key.
2464
2465 * posix.c (scm_sync): #else was missing.
2466
2467 * error.c, error.h: append _key to names scm_num_overflow and
2468 scm_system_error.
2469
2470 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2471 of consing an empty list.
2472 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2473 of macros, saves code and string space.
2474 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2475 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2476 lower case. Rename scm_syserror_m to scm_syserror_msg.
2477 error.h: prototypes for new procedures.
2478
2479 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2480
2481 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2482
2483 * error.c, error.h: setup scm_num_overflow key.
2484
2485 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2486 Remove definition of SCM_OVSCM_FLOW.
2487
2488 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2489
2490 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2491 explicit message and args.
2492
2493 * error.c, error.h, __scm.h: change system_error_sym to
2494 scm_system_error.
2495
2496 * error.c (system_error_sym): remove leading %% from the Scheme name
2497 "%%system-error".
2498
2499 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2500
2501 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2502
2503 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2504 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2505 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2506 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2507 renamed. (These were introduced by unsupervised name
2508 substitution.)
2509
2510 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2511
2512 * print.c: Added code for detection of circular references during
2513 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2514 a hook for printing of closures (accessible via print options).
2515 This leads to a split of calls to scm_iprin1 into two classes:
2516 elementary print operations (e. g. the code which prints a smob)
2517 still use scm_iprin1 while top level calls (like scm_display) use
2518 scm_prin1. scm_prin1 begins by clearing the data structure used
2519 to record reference information.
2520
2521 * print.h: Added declarations of scm_prin1 and scm_prlist.
2522
2523 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2524
2525 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2526
2527 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2528
2529 * error.c (err_head): scm_iprin1 --> scm_prin1
2530
2531 * debug.c: Adjusted header comment.
2532
2533 * tags.h: Typo.
2534
2535 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2536
2537 * strerror.c: Doc fix.
2538
2539 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2540
2541 * gdbint.c (gdb_read): Now possible to run during GC.
2542 (unmark_port, remark_port): New functions.
2543
2544 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2545
2546 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2547 of allocating a new string object. Also, increase size by
2548 the factor 2 instead of 1.5.
2549
2550 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2551
2552 * __scm.h (SCM_P): Corrected to run under traditional C.
2553
2554 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2555 removed.
2556
2557 * async.c: Calls to scm_sysintern corrected.
2558
2559 * async.h (scm_async_clock): Redundant declaration removed.
2560
2561 * continuations.c (scm_dynthrow): Redundant declaration removed.
2562
2563 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2564 Definition typos corrected.
2565
2566 * debug.h: Missing declarations of functions in debug.c added
2567 (lots).
2568
2569 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2570 Missing declarations to functions in eval.c added.
2571
2572 * filesys.c: Possibly uninitialized variable rv.
2573
2574 * gc.h (scm_object_addr, scm_unhash_name): Missing
2575 declarations of functions defined in gc.c added.
2576
2577 * genio.c: Possible typos str_data -> wstr_data. ???
2578
2579 * genio.c: Possibly unintended shadowing of local variable
2580 `int c' (gotos out of scope of inner `c'). ???
2581
2582 * init.c: Uninitialized `SCM last' may be used.
2583
2584 * ioext.h: (scm_sys_isatty_p): Typo.
2585
2586 * list.h (scm_list_head): Missing prototype for function in
2587 list.c added.
2588
2589 * numbers.c (scm_two_doubles): Changed from extern to static
2590 (is used only within numbers.c).
2591
2592 * numbers.h: Repeated declarations removed.
2593
2594 * ports.h (scm_close_all_ports_except): Declaration for the
2595 function defined in ports.c added.
2596
2597 * posix.h: Missing declarations added.
2598
2599 * procs.h (scm_make_subr_opt): Missing declaration added.
2600
2601 * socket.h (scm_sys_gethost): Missing declaration added.
2602
2603 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2604
2605 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2606 Missing declarations added.
2607
2608 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2609
2610 * struct.c: Uninitialized variable `SCM answer' may be used.
2611
2612 * unif.c (l2ra): Declaration prototype.
2613
2614 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2615 defined in ramap.c).
2616
2617 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2618 Redundant declarations removed (they are in ramap.h).
2619
2620 * variable.h (scm_make_udvariable,
2621 scm_make_undefined_variable): Declaration corrected to
2622 correspond variable.c.
2623
2624 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2625 Missing declarations added.
2626
2627 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2628
2629 * Makefile.in (distclean): Don't forget to delete fd.h.
2630
2631 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2632
2633 * fd.h.in, tags.h: Trivial cleanups.
2634
2635 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2636 marksweep.h just declared functions from gc.c.
2637 * gc.h, libguile.h: Don't #include "marksweep.h".
2638 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2639 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2640 dependencies updated.
2641
2642 * libguile.h: Don't #include "files.h"; it's been deleted.
2643
2644 * files.c (scm_sys_delete_file): Moved to filesys.c.
2645 File is now empty; deleted.
2646 * files.h: Deleted.
2647 * filesys.c: scm_sys_delete_file is now here. Remove
2648 #if's; they seem to rely on remnants of an old portability
2649 regimen. If the problems come up again, solve them properly,
2650 using autoconf. Specifically: Don't test M_SYSV, and #define
2651 remove to be unlink if it's #defined; don't use remove just
2652 because HAVE_STDC_HEADERS is #defined.
2653 * filesys.h: Add declarations for scm_sys_delete_file.
2654 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2655 files.o, files.h, files.c, and files.x.
2656 * init.c: Don't #include "files.h", and don't call scm_init_files.
2657
2658 Use SCM_P instead of PROTO; the latter intrudes on the user's
2659 namespace.
2660 * params.h: Deleted; definition of SCM_P moved to...
2661 * __scm.h: ... here, where it replaces PROTO macro.
2662 * libguile.h, smob.h: Don't #include "params.h".
2663 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2664 smob.h: Fix prototypes accordingly.
2665 * Makefile.in: Update dependencies.
2666 (inner_h_files): Remove params.h.
2667
2668 * gc.c: #include "gc.h"; every module should include its header,
2669 to let the compiler cross-check the declarations against the
2670 definitions.
2671
2672 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2673 simpos.h: #include "libguile/__scm.h".
2674
2675 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2676
2677 * init.c: Don't forget to #include smob.h and init.h.
2678 * Makefile.in: Dependencies updated.
2679
2680 * smob.h: Use PROTO instead of #if __STDC__.
2681
2682 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2683
2684 * __scm.h: Doc fixes.
2685
2686 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2687 <angles>; this allows `make depends' to work properly.
2688
2689 * libguile.h: #include smob.h and pairs.h before the others; they
2690 define typedefs used by other headers.
2691
2692 C files should #include only the header files they need, not
2693 libguile.h (which #includes all the header files); the pointless
2694 recompilation was wasting my time.
2695 * Makefile.in (all .o dependency lists): Regenerated.
2696 * libguile.h: Don't try to get a definition for size_t here...
2697 * __scm.h: Do it here.
2698 * _scm.h: Since this is the internal libguile header, put things
2699 here that all (or a majority) of the libguile files will want.
2700 Don't #include <libguile.h> here; that generates dependencies on
2701 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2702 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2703 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2800 * weaks.c: Get "weaks.h".
2801
2802 * stackchk.h: #include "libguile/debug.h",
2803
2804 * print.h, read.h: #include "options.h", since everyone who uses
2805 either of these files will need that.
2806
2807 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2808 anyone who uses this file will need them to define the smob
2809 printing functions. Also, get markers.h, since people will need
2810 to #define the mark functions.
2811
2812 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2813 * ports.h: ... to here.
2814
2815 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2816 don't rely on archaic C default type rules.
2817
2818 * fports.h: #include "libguile/ports.h", since you need that in
2819 order to parse this.
2820
2821 * genio.h: #include "libguile/print.h", because you need that to
2822 parse this; don't bother #including "ports.h", since print.h gets
2823 that.
2824
2825 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2826
2827 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2828 this; it's now a reference to an element of *scm_root.
2829
2830 * debug.h: Don't #include "options.h"; the compiler won't be able
2831 to find that once the headers are installed; instead, #include
2832 "libguile/options.h".
2833 * gc.h: Same, with marksweep.h.
2834 * mbstrings.h: Same, with symbols.h.
2835 * scmhob.h: Same, with _scm.h.
2836 * smob.h: Same, with params.h.
2837
2838 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2839 C files; there's no need for this, and it forces recompilations
2840 unnecessarily.
2841
2842 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2843
2844 * error.c (scm_error): declare scm_error_callback.
2845
2846 * error.h: prototype for scm_error_callback.
2847
2848 * __scm.h: define lgh_error.
2849 (SCM_SYSERROR): redefine using lgh_error.
2850
2851 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2852
2853 * error.c (scm_error): new procedure.
2854
2855 * error.h: prototype for scm_error.
2856
2857 * Makefile.in (install): install scmconfig.h from the current
2858 directory, not $(srcdir).
2859
2860 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2861
2862 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2863 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2864 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2865 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
2866 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
2867 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2868 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2869 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2870 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2871 vports.h, weaks.h: #include "libguile/__scm.h", not
2872 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2873 dependencies are within libguile properly.
2874
2875 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2876
2877 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2878 when scmconfig.h doesn't exist.
2879
2880 * load.c (scm_sys_try_load): Correct spelling.
2881
2882 * feature.c (scm_loc_features): Make this static.
2883
2884 * Makefile.in (libpath.h): Omit trailing slash from path. We
2885 shouldn't require it of users, so why put it here?
2886
2887 Move code to initialize and search %load-path from ice-9 to C
2888 code, so we can use the load-path to find the ice-9 boot code;
2889 this makes it easier to run Guile without installing it. See
2890 corresponding changes in guile/Makefile.in.
2891 * feature.c: Move stuff concerned with the load path to load.c.
2892 (scm_compiled_library_path): Deleted.
2893 Don't #include libpath.h here.
2894 * feature.h: Don't mention scm_compiled_library_path.
2895 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2896 <sys/stat.h>, and <unistd.h> (if present).
2897 (R_OK): #define if the system hasn't deigned to.
2898 (scm_loc_load_path): New variable.
2899 (scm_init_load_path, scm_sys_search_load_path,
2900 scm_sys_try_load_path): New functions.
2901 (scm_init_load): Initialize scm_loc_load_path to point to the
2902 value cell of the Scheme %load-path variable.
2903 * load.h: Add declarations for scm_sys_search_load_path,
2904 scm_sys_try_load_path.
2905 * init.c: Call scm_init_load_path.
2906 * Makefile.in (feature.o, load.o): Dependencies updated.
2907
2908 * load.c, load.h: Rewrite using PROTO macro.
2909
2910 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2911
2912 * gc.c (scm_cellp): New function: C predicate to determine if an
2913 SCM value can be regarded as a pointer to a cell on the heap.
2914
2915 * gc.h: Added declaration of scm_cellp.
2916
2917 * gdb_interface.h: New file: The GDB interface header from the GDB
2918 distribution.
2919
2920 * gdbint.c: New file: GDB interface.
2921
2922 * gdbint.h: New file: GDB interface.
2923
2924 * libguile.h: Added #include <libguile/gdbint.h>.
2925
2926 * init.c (scm_boot_guile): Added scm_init_gdbint.
2927
2928 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2929 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2930 found if object files and source are kept separate).
2931
2932 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2933
2934 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2935
2936 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2937
2938 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2939 TK_SRC_DIR; they're not relevant any more.
2940
2941 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2942 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2943
2944 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2945
2946 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2947 search path, so we can find the <libguile/MUMBLE.h> headers.
2948
2949 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2950
2951 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2952 implicit in the .c.o rule.
2953 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2954 $(CC) already.
2955
2956 Put the library path in a header file, instead of passing it on
2957 the command line in every compilation.
2958 * Makefile.in (libpath.h): New target.
2959 (feature.o): Depend on libpath.h.
2960 (clean): Delete libpath.h.
2961 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2962 * feature.c: ... #include "libpath.h" here.
2963 * .cvsignore: Ignore libpath.h.
2964
2965 Don't install the unwashed masses of Guile header files in the
2966 main #include path; put most of them in a subdirectory called
2967 'libguile'. This avoids naming conflicts between Guile header
2968 files and system header files (of which there were a few).
2969 * Makefile.in (pkgincludedir): Deleted.
2970 (innerincludedir): New variable; this and $(includedir) are enough.
2971 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2972 (installed_h_files): Divide this up. Now this variable lists
2973 those header files which should go into $(includedir) (i.e. appear
2974 directly in the #include path), and ...
2975 (inner_h_files): ... this new variable says which files appear in
2976 a subdirectory, and are referred to as <libguile/mumble.h>.
2977 (h_files): List them both.
2978 (install): Create innerincludedir, not pkgincludedir. Put
2979 the installed_h_files and inner_h_files in their proper places.
2980 (uninstall): Corresponding changes.
2981 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2982 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2983 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2984 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2985 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2986 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2987 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2988 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2989 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2990 vports.h, weaks.h: Find __scm.h in its new location.
2991 * __scm.h: Find scmconfig.h and tags.h in their new locations
2992 (they're both "inner" files).
2993
2994 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2995
2996 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2997
2998 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2999
3000 * posix.c: Doc fixes.
3001
3002 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
3003
3004 * socket.c: Don't include a prototype for inet_aton; just use a
3005 K&R style declaration, to avoid warnings but minimize the chance
3006 of conflicts with the system.
3007
3008 On NextStep, <utime.h> doesn't define struct utime, unless we
3009 #define _POSIX_SOURCE before #including it.
3010 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
3011 * acconfig.h: New comment text for above CPP symbol.
3012 * configure.in: Call it.
3013 * posix.c: #define _POSIX_SOURCE if it seems necessary.
3014
3015 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
3016 in the list.
3017 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
3018 testing for __EMX__.
3019
3020 * posix.c: #include <libc.h>, if it exists.
3021
3022 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
3023 don't even know if the latter exists.
3024
3025 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
3026 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
3027 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
3028
3029 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
3030 header files don't.
3031 (scm_init_posix): Use them when initializing the Scheme constants
3032 of the same name.
3033
3034 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3035
3036 * Makefile.in (libdir, includedir, bindir): Use the
3037 autoconf-supplied values, instead of deriving them ourselves.
3038 (pkgincludedir, datadir, pkgdatadir): New variables.
3039 (install, uninstall): Put the header files in a special
3040 subdirectory, not in the main search path.
3041
3042 * Makefile.in (ALL_CFLAGS): Provide the proper value for
3043 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
3044
3045 * Makefile.in (IMPLPATH): Deleted; never used.
3046
3047 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
3048 on the Tcl/Tk source any more.
3049 (INCLUDE_CFLAGS): Remove references to the above.
3050
3051 * Makefile.in (version.o): Corrected dependencies.
3052
3053 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
3054
3055 * libguile.h: #include "version.h"
3056
3057 * init.c (scm_boot_guile): Call scm_init_version.
3058 * gscm.c (gscm_run_scm): Call scm_init_version.
3059
3060 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
3061 GUILE_VERSION): AC_DEFINE these.
3062 (acconfig.h): #undef the above symbols.
3063
3064 * Makefile.in (libobjs): Add version.o.
3065 (installed_h_files): Add version.h.
3066 (c_files): Add version.c.
3067 (gen_c_files): Add version.x.
3068 (version.o): New rule.
3069 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
3070 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
3071 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
3072 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
3073 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
3074 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
3075 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
3076 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
3077 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
3078 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
3079 weaks.o): Add version.h to dependency lists.
3080 (markers.o): Remove duplicate rule.
3081
3082 * version.h: New file.
3083
3084 * version.c: New file.
3085
3086 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3087
3088 * symbols.c (scm_strhash): scm_downcase is now a function, not an
3089 array; use it appropriately. Since GCC is quite happy to
3090 subscript functions, it never warned us about this; we should use
3091 -Wpointer-arith in the future. I guess we never tested
3092 case-insensitivity.
3093
3094 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3095
3096 * socket.c: Doc and copyright fixes.
3097
3098 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3099
3100 * debug.c: Fixed and improved gdb support.
3101
3102 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3103
3104 * socket.c: Added declaration of inet_aton to avoid compiler
3105 warning. (Hope this solution is correct.)
3106
3107 * stime.c: Added declaration of ftime. (This is missing in
3108 Solaris 2 headers.)
3109
3110 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
3111
3112 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3113
3114 * Makefile.in (c_files): add strerror.c.
3115
3116 * strerror.c: new file from Emacs' sysdep.c.
3117 maybe configure should also check for sys_errlist.
3118
3119 * configure.in (AC_REPLACE_FUNCS): add strerror.
3120
3121 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3122
3123 * debug.c (scm_init_debug): Added initialization for
3124 scm_evaluator_traps.
3125
3126 * debug.h, debug.c: Various name changes.
3127 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
3128 "debug-options-interface". See commentary in options.c.
3129
3130 * options.h, options.c: Options now have documentation strings.
3131 Also added a long explanatory commentary.
3132
3133 * eval.c, print.h, print.c, read.h, read.c: Modifications to
3134 run-time options.
3135
3136 * gscm.c, init.c, root.c, throw.c: Bug fixes:
3137 last_debug_info_frame is now updated in all cases.
3138
3139 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
3140 checking.
3141
3142 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3143
3144 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
3145 Added option STACK_CHECKING.
3146
3147 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3148
3149 * Makefile.in: Added {debug,options,srcprop}.{h,c}
3150
3151 * __scm.h: Removed symbols for debugging support.
3152
3153 * acconfig.h: Added symbols for debugging support.
3154
3155 * configure.in: Added user option for debugging support.
3156 --enable-debug will include the debugging code into libguile.a.
3157
3158 * continuations.c (scm_make_cont): Enlarged the #if 0 around
3159 scm_relocate_chunk_to_heap.
3160
3161 * debug.c: New file: low-level debugging support. It also
3162 includes support for debugging with gdb. (The extensions to gdb
3163 are written by Per Bothner at Cygnus.)
3164
3165 * debug.h: New file: low-level debugging support.
3166
3167 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
3168 argument pairs. Extensive modifications to the debugging
3169 evaluator. Added "SECTION:" commentaries to clarify what happens
3170 when, during double compilation. Renamed EVALIMP --> EVALIM.
3171 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
3172 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
3173 the beginning of the file. New procedure: scm_unmemocopy.
3174 Added some global state variables needed by the debugging
3175 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3176 check_entry, check_apply, check_exit, debug_options and
3177 evaluator_traps. New acro: undefine.
3178
3179 * eval.h: Renamed EVAL --> XEVAL.
3180
3181 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3182 --> scm_make_weak_key_hash_table.
3183
3184 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3185 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3186
3187 * libguile.h: Conditionally include debug.h
3188
3189 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3190 scm_object_properties shouldn't return handle. `handle' now gets
3191 initialized in scm_set_object_properties_x. scm_object_properties
3192 doesn't any longer create an entry in scm_object_whash.
3193
3194 * options.c: New file: handling of run time options.
3195
3196 * options.h: New file: handling of run time options.
3197
3198 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
3199
3200 * print.c: New procedure: scm_print_options
3201
3202 * print.h: Defines for print options.
3203
3204 * read.c: New procedure: scm_read_options
3205
3206 * read.h: Defines for reader options.
3207
3208 * root.h: Added scm_source_whash among scm_sys_protects.
3209
3210 * srcprop.c: New file: source properties.
3211
3212 * srcprop.h: New file: source properties.
3213
3214 * throw.c (jbsmob): Jump buffers are now correctly allocated.
3215 (Bug found by A. Green.)
3216
3217 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3218
3219 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3220
3221 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3222
3223 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3224
3225 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3226 and should be called by the final client.
3227
3228 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3229
3230 * gc.h: Use the PROTO macro when declaring functions.
3231 * gc.c: Use the PROTO macro when declaring static functions.
3232 Remove the CPP hair around function definitions.
3233
3234 * gc.c (scm_init_storage): Initialize scm_asyncs.
3235
3236 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3237 preprocessor symbol; "__scm.h" is where it might get #defined.
3238 * __scm.h: Similar: #include <scmconfig.h> before testing
3239 HAVE_LIMITS_H.
3240
3241 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3242
3243 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3244
3245 * init.c (scm_boot_guile): Add init_func argument; call
3246 (*init_func) instead of calling scm_appinit; it's ucky to
3247 hard-code names for the user's procedures.
3248 * init.h (scm_boot_guile): Adjust declaration.
3249
3250 * __scm.h (PROTO): New macro, for declaring functions with
3251 prototypes.
3252
3253 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3254 eliminate all the __STDC__ conditionals.
3255 (scm_boot_guile): Add declaration.
3256 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3257 Remove __STDC__ conditionals around function definitions; the
3258 declarations in init.h will provide the same information, more
3259 usefully.
3260
3261 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3262 complain about it in the error message; the error message is
3263 adequate without that note, and there's nothing the user can do
3264 about it.
3265
3266 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3267
3268 * Makefile.in (ancillary): Drop def.sed.
3269
3270 * posix.c (scm_init_posix): Use numeric values, rather than
3271 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3272 F_OK. The symbols aren't available on some systems, and I'm
3273 pretty sure their values are fixed by common widespread practice.
3274 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3275
3276 More functions unavailable on some systems.
3277 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3278 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3279 check for.
3280 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3281 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3282 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3283 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3284 stub that signals an error as the #else.
3285
3286 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
3287
3288 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
3289
3290 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
3291
3292 * unif.c: include ramap.h.
3293
3294 * read.c (endif): case_insensative_p renamed case_insensitive_p.
3295
3296 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
3297
3298 * ports.c: include sys/ioctl.h.
3299
3300 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
3301
3302 * configure.in: check for sys/ioctl.h.
3303
3304 * ports.c: include <malloc.h> not "malloc.h".
3305
3306 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3307
3308 * fports.c: remove ttyname and tmpnam declarations.
3309
3310 * posix.c: fewer ttyname declarations.
3311
3312 * fports.c: include <string.h> not "string.h".
3313
3314 * init.c, ioext.c: include string.h and unistd.h.
3315
3316 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3317
3318 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
3319 genio.c, simpos.c, vports.c: include string.h.
3320
3321 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
3322
3323 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
3324 scm_sizet to int.
3325 (scm_addr_buffer_size): change type from scm_sizet to int.
3326 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
3327 from scm_sizet to int.
3328
3329 * error.c: include unistd.h.
3330
3331 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
3332 defined.
3333
3334 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
3335
3336 * __scm.hd, def.sed: deleted.
3337
3338 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
3339
3340 Changes for NeXT, suggested by Robert Brown.
3341 * configure.in: Call AC_TYPE_MODE_T.
3342 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
3343 NeXT. Put header file list in alphabetical order.
3344 * configure, scmconfig.h.in: Regenerated.
3345 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
3346
3347 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
3348 for strerror.
3349
3350 * acconfig.h: New file, providing documentation for the CPP
3351 symbols defined in configure.in
3352 * acconfig-1.5.h: Removed; superceded by the above.
3353
3354 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
3355
3356 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
3357
3358 * fports.c (scm_open_file): don't return #f, throw error.
3359
3360 * ioext.c (fileno): renamed from %fileno.
3361 (soft-fileno): deleted.
3362
3363 * ports.c (scm_port_revealed): don't need to check for -1 from
3364 scm_revealed_count.
3365 (scm_set_port_revealed_x): return unspecified, not #f.
3366
3367 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3368
3369 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3370
3371 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3372
3373 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3374

3376
3377 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3378 This is necessary on Ultrix, and doesn't hurt portability.

3380 * Makefile.in (dist-dir): New target, implementing a new dist system.
3381 (installed_h_files): Put in alphabetical order.
3382 Remove duplicate entries for markers.h and unif.h.

3384 (ancillary): Renamed from anillery; all uses changed. Remove
3385 PLUGIN; it's a directory, and needs special treatment in dist-dir.

3387
3388 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3389
3390 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:

3404 Remove leading % from scheme names.

3458 * ports.c (scm_ports_prehistory): size malloced here doesn't
3459 matter so long as it is non-0 (got rid of "* 4").
3460
3461 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3462
3463 * gscm.h: gscm_mkarray eliminated (presumably was not being used

3480
3481 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3482 handled correctly (SCM_FREEP was applied to them) -- test for
3483 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
3484 being overwritten with #f. (brown@grettir.bibliotech.com)

3531 * pairs.c (scm_delq_x): never throw an error.
3532
3533 * vectors.c (scm_make_vector): made the default vector fill argument
3534 into '() (much more useful than the previous value, "#unspecified")
3535

3537
3538 * ports.c (scm_add_to_port_table): Added fields

3639 functions. hash, hashq, hashv, hashx.
3640
3641 * tags.h: made wvect an option bit of vector.

3677 set the multi_byte flag correctly in symbols. This is wrong.
3678 intern_obbary_soft and msymbolize should take an extra parameter.

3680 The weird symbol syntax is also a bit bogus (emacs doesn't quite
3681 cope).

3842
3843 * elisp.c (new file): dynamic scoping and other bits for
3844 elisp. Don't use this yet unless you specificly want to
3845 hack on elisp emulation.
3846
3847 * dynwind.c (scm_dowinds): When entering or leaving a dynamic
3848 scope created by scm_with_dynamic_bindings_operation_x, swap
3849 the bindings of that scope with the corresponding globals.
3850
3851 * continuations.c (scm_make_cont): when a continuation is captured,
3852 relocate the continuation stack chunks registered on the wind chain
3853 to the heap.

3856
3857 * eval.c (SCM_CEVAL): if the function position evaluates
3858 to a macro, process it accordingly. (Previously, macros were
3859 handled only if the function position was a symbol naming a
3860 variable bound to a macro).
3861
3862 Sat Jan 20 23:21:37 1996 Tom Lord <lord@beehive>
3863
3864 * eval.c (scm_m_set): allow multi-variable set! like
3865 (set! x 1 y 2 z 3).
3866

3868
3869 * ports.h fports.c vports.c marksweep.c gc.c strports.c: moved the
3870 STREAM of ports into the port table and replaced it with a
3871 port-table index.
3872
3873 * repl.c (iprin1): added tc7_mb_string -- same as tc7_string.
3874
3875 * marksweep.c (scm_gc_mark): added tc7_mb_string -- same as tc7_string.
3876
3877 * mbstrings.c (new file): functions on multi-byte strings.
3878
3879 * tags.h (scm_typ7_string, scm_typ7_mb_string): added a tag
3880 for multi-byte strings. Moved the string tag.
3881
3882 * chars.h chars.c repl.c (many functions): made scm_upcase and
3883 scm_downcase functions that are safe for extended character sets.
3884
3885 Changed the range of integer->char.
3886
3887 Changed the type of SCM_ICHR.

3895
3896 * guile.c (gscm_is_gscm_type): New function. (Without this how will we
3897 know that it's safe to pass an object to gscm_get_type?)
3898 (gscm_get_type): Fix tyop in error message.
3899
3900 * variable.c (scm_variable_ref): fixed assertion test.
3901 (Robert STRANDH <strandh@labri.u-bordeaux.fr>)

3903 * gscm.h: fixed several prototypes, notably gscm_vref.
3904 Add gscm_is_eq and temporarily commented out gscm_eq (see
3905 the note in gscm.h near gscm_eq if this change effects your
3906 code).
3907 (Reported by Mark Galassi <rosalia@sstcx1.lanl.gov>)
3908
3909 * pairs.c (scm_obj_length): see next entry.
3910
3911 * gscm.h (gscm_obj_length): A way to get an integer
3912 length for lists, strings, symbols (treated as strings),
3913 and vectors. Returns -1 on error.
3914
3915 * eq.c (scm_equal_p): fixed smob case.
3916 (William Gribble <grib@arlut.utexas.edu>)
3917
