11 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
12 throw.c: Update copyright years; these files have been worked on
13 significantly in 1997, but only had copyright years for 1996.
14 Also, change name of copyright holder on some from Mikael
15 Djurfeldt to Free Software Foundation; he has signed papers
16 assigning the changes to the FSF.
18 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
19 reason not to give the user the option.
21 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
22 Return #f on end-of-file when scanning table (i.e. when called
23 with no arguments). Try to catch errors, when we can.
24 * posix.c (scm_getgrgid, scm_getpwuid): Same.
26 * script.h (scm_shell_usage, scm_compile_shell_switches): New
27 external declarations. These are useful.
29 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
31 * posix.c: don't include <sys/select.h> or define macros for
32 select, since they were not used in this file.
34 * filesys.c (scm_select): make the fifth parameter microseconds,
35 not milliseconds. let the fourth parameter be either a real value
36 or an integer or #f. The first, second and third arguments can
37 now be vectors: the type of the corresponding return set will be
39 (set_element, get_element): new static procedures.
41 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
43 * strports.c (scm_eval_string): New function.
44 (scm_eval_0str): Trivially re-implemented in terms of
46 * strports.h (scm_eval_string): New extern decl.
48 * net_db.c (h_errno): Add extern decl for this.
50 * fports.c (local_pclose): New function.
51 (scm_pipob): Use it in the initializer here.
54 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
55 Use a meaningful error message when signalling an error. For
56 this, scm_gethost must check h_errno rather than errno.
58 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
60 * Makefile.in: Regenerated, using automake-1.1p.

67 * script.c (scm_compile_shell_switches): don't append (quit) if
69 (scm_shell): call scm_exit_status and exit on the result of the
72 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
74 Ensure that shared substrings are handled properly when passed to
75 a system call or other foreign function. Many thanks to Tim
77 * symbols.h (SCM_COERCE_SUBSTR): new macro.
78 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
79 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
80 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
81 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
82 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
83 (scm_display_error_message): use RO macros when strings may be RO.
84 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,

89 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
90 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
91 scm_strftime), vports.c (scm_make_soft_port): use
92 SCM_COERCE_SUBSTR to make sure shared substrings are
95 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>

103 * dynl-shl.c: Completely replaced with new code from Bernard
106 * script.c (scm_ice_9_already_loaded): New variable.
107 (scm_compile_shell_switches): Use it.
109 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
111 * filesys.c (scm_input_waiting_p): add missing third argument to

123 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
125 * Makefile.am (check-local): New target, which causes 'make check'
126 to run gh_test_c and gh_test_repl, with some trivial input.
127 * Makefile.in: Rgnrtd.
129 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>

134 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
136 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
137 sure how this was supposed to work.
138 (scm_async_click): don't send SCM_TICK_SIGNAL.
139 (scm_init_async): don't initialize %tick-thunk.
141 * the following change doesn't affect the Scheme interface:
142 gc-thunk is called at the end of garbage collection. however it's
143 no longer implemented by pretending it's a signal.
145 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
146 system async corresponding to scm_gc_thunk.
147 * async.h: declare scm_gc_async.
148 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
149 gc-thunk directly, instead of going through a signal handler.
150 (scm_gc_async): new variable, points to the GC system-async.
151 (scm_init_async): save the GC async as scm_gc_async instead
152 of using system_signal_asyncs.
153 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
155 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
157 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
158 Don't screw up if we're interrupted.
159 * Makefile.in: Regeneradet.
161 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
163 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
165 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
166 we're not using AM_INIT_GUILE_MODULE any more.
167 * Makefile.in: Reneregated.
169 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
171 Functions for finding variable bindings, grace à Tim Pierce.
172 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
173 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
175 Get 'make dist' to work again.
176 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
177 * Makefile.in: Regenerated, like a surry without a fringe on top.
179 Changes for reduced Guile distribution: one configure script,
181 * configure.in, configure: Removed.
182 * acconfig.h, acinclude.m4: Moved to parent directory, where the
183 real configure script lives.
184 * Makefile.in, scmconfig.h.in: Regenerated.
186 * init.c: #include "script.h", to get prototype for script.c's
189 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
191 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
192 scm_must_malloc, not raw malloc.
194 * script.c (scm_compile_shell_switches): Dyke out debugging output
197 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
199 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
201 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
202 system has them. Hope this is safe. Previously
203 sys/timeb.h was included if HAVE_FTIME was defined or if
204 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
205 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
207 * ioext.c (scm_setfileno): add missing third argument to
210 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
212 * eq.c (scm_equal_p): Correctly compare strings of different
213 varieties. (Thanks to Tim Pierce.)
215 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
217 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
218 #! block comment must occur on a line all by itself.
220 Move most of the guts of shell command processing into libguile,
221 so guile.c can be very small (and eventuallly auto-generated. (I
222 mean, generated mechanically, not self-generated. Hmm.))
223 * guile.c, script.c, script.h: New source files.
224 * init.c (scm_boot_guile_1): Call scm_init_script.
225 * libguile.h: #include "script.h".
226 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
227 targets, for new executable.
228 (libguile_la_SOURCES): Mention script.c.
229 (modinclude_HEADERS): Add script.h.
230 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
231 not dynamic linking is enabled. This is because we're generating
232 executables now. Move CY_AC_WITH_THREADS call after those, so the
233 values of cy_cv_threads_libs captures the libs chosen above.
234 * Makefile.in, configure, aclocal.m4: Regenerated.
236 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
237 We don't maintain this interface any more, and it just confuses
240 * alloca.c: #include <scmconfig.h>, not <config.h>.
241 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
242 it'll get included in disties.
244 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
246 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
247 be distributed, because they confuse people.
248 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
250 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
252 * configure.in: check for presence of gethostent (not present on
254 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
255 * configure, scmconfig.h.in: Regenerated.
257 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
259 * backtrace.c (scm_backtrace): Split message string across
260 newlines properly. GCC is more tolerant of this than other
263 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
265 Merge threads directory into libguile.
266 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
267 threads.h: New source files.

269 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
271 (modinclude_HEADERS): Add threads.h, coop-defs.h.
272 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
273 coop-threads.c.cygnus, coop-threads.h.cygnus.
274 * configure.in: If we're using threads, include threads.o in
276 * _scm.h, libguile.h: threads.h lives in this directory now.
277 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
278 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
279 currently used, but brought along for information's sake.
280 * ChangeLog-threads: log from old 'threads' directory.
281 * Makefile.in, configure: Rebuilt.
283 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
285 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
288 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
290 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
292 Merge GH interface library into libguile.
293 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
294 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
295 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
296 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
298 (EXTRA_libguile_la_SOURCES): ... here.
299 (pkginclude_HEADERS): Add variable, to get gh.h installed.
300 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
301 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
302 New variables, describing how to build the gh test programs.
303 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
304 build the test programs, and we probably should have been linking
305 libguile.la against them all along, to support AIX shared libs.
306 Add cflags for threads to CFLAGS; add libs for threads to new
307 variable THREAD_LIBS, used in Makefile.am.
308 * ChangeLog-gh: log from old `gh' subdirectory.
309 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
311 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
313 * acconfig.h: Undo change of Apr 9; including the definition of
314 PACKAGE in the guile headers conflicts with applications' own
316 * scmconfig.h.in: Regenerated.
318 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

322 * filesys.h: Added prototype.
324 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
325 when PROC is receiving no arguments.
327 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
329 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
330 have S_IFSOCK. This is the case under Ultrix.
332 * posix.c (scm_status_exit_val, scm_status_exit_val,
333 scm_status_term_sig, scm_status_stop_sig): Modified to work with
334 Ultrix versions of WIFSTOPPED, etc., which assume that their
335 arguments are lvalues (hmm).
337 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
341 * throw.c: Doc fixes; rearranged.
343 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
345 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
347 * acconfig.h: Added entry for PACKAGE.
348 * scmconfig.h.in: Regenerated.
350 Changes to work with automake-1.1n, which has better libtool support.
351 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
352 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
354 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
356 * Makefile.in: Rebuild.
358 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
360 * stime.c (scm_mktime): take an optional zone argument.
361 (scm_localtime): check putenv return value.

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

1958 objects. (Earlier, only closures were recorded.)
1960 * procprop.h: Added declaration of scm_i_name.
1962 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1963 (scm_make_gsubr): Record names of compiled closures.
1965 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1967 * debug.c, debug.h: Removed obsolete code.
1969 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1970 stacks.c: Renamed regs --> scm_contregs.
1972 * print.c (scm_free_print_state): Cleanup print state before
1973 returning it to pool. It is better to do it here than in
1974 scm_prin1 since scm_prin1 is called often.
1976 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1977 s_set_source_property_x): Check that first argument is a pair or a
1980 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1981 scm_i_line, scm_i_column and scm_i_breakpoint global.
1983 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1984 (scm_boot_guile_1): Added calls to scm_init_backtrace and

1994 backtrace.h, stacks.c and stacks.h.
1996 * symbols.c (scm_sym2ovcell): Fixed documentation.
1998 * _scm.h (min, max): Added.
2000 * async.c: Moved `min' macro to _scm.h.
2002 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
2003 SCM_BACKTRACE_INDENT.
2005 * eval.c: Added new debug options `maxdepth' and `indent'.
2007 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
2009 * print.h: Added selector SCM_PRINT_STATE.
2011 * print.c: New functions: scm_make_print_state,

2014 * print.h: Added declarations for scm_make_print_state,
2015 scm_free_print_state.
2017 * debug.c (scm_m_start_stack): New acro.
2019 * debug.h: Small cleanup.
2021 * init.c (scm_boot_guile_1): Moved scm_init_debug below

2044 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
2045 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
2046 declare functions with prototypes. (Patch thanks to Marius
2049 More prototype-related changes from Marius Vollmer:
2050 * gdb_interface.h: Wrapped header file in #ifdef/#endif
2051 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
2052 * ports.h (ptobfuns): Added prototypes. This means some casting in
2054 * fports.c: Added casts for initializations, since the functions
2055 are defined to take FILE * as their stream argument, not SCM.
2056 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
2057 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
2058 to `char *str_data' to conform to prototype.
2060 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2062 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
2064 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
2066 * stime.c, stime.h: use SCM_P method.
2068 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2070 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
2071 be given at least two arguments. Insist that lst's last element
2072 be a list, but don't make any requirements of its predecessors.
2074 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2076 * eval.c (scm_nconc2last): Revert last change; there seems to be
2077 other stuff going on here.
2079 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2081 * eval.c (scm_nconc2last): Make sure that each element of lst
2082 (which is a list of argument lists, except for the tail) is a
2083 proper list, i.e., finite and terminated by '().
2085 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2087 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
2090 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
2091 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
2094 * vectors.c (scm_make_vector): Fill vectors with the undefined
2095 value, to help make Guile Scheme code more portable to other
2098 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
2099 * symbols.h, tags.h: Doc fixes.
2101 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
2103 * async.c (scm_take_signal): Doc fixes.
2105 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
2107 * numbers.c (scm_divbigint): When the remainder is zero, we don't
2108 want to subtract it from the modulus; we just want to leave it
2111 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
2113 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
2116 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
2118 * throw.c (scm_catch_apply): Finished implementation of
2121 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2123 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
2125 (scm_init_filesys): set "i/o-extensions" feature.
2128 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
2130 * Makefile.in (root.o): Correct dependencies.
2132 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
2134 * Makefile.in: Added dependency entry for root.o.
2136 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
2137 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
2139 * init.c (scm_start_stack): Set initial root continuation number
2142 * procs.c: New function: scm_thunk_p.
2144 * procs.h: Added declarations of scm_thunk_p.
2146 * root.c: Renamed `call-with-new-root' -->
2147 `call-with-dynamic-root'.
2148 (cwdr): Removed allocation of new root state. This should be done
2149 separately by use of scm_make_root.
2150 (scm_apply_with_dynamic_root): New function: Does what it
2151 sounds like. Needed when spawning threads.
2153 * root.h: Added member last_debug_frame to root state.
2154 Added #include "libguile/debug.h"
2156 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
2157 arguments. The motivation is that code in root.c needs catch
2158 functionality, and we want to avoid code duplication.
2159 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2160 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2161 handlers that run without popping the stack into the dynwind
2164 * throw.h: Added prototypes for scm_catch_apply and
2167 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2169 * root.h (scm_root, scm_set_root): Decouple thread support details
2170 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2171 SCM_SET_THREAD_LOCAL_DATA.
2173 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2174 and tortoise scanning loop.
2176 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2178 * Makefile.in: Rebuild dependencies.
2180 * libguile.h: #include "libguile/print.h" before "smob.h", since
2181 the latter uses the print_state structure.
2183 * throw.c (scm_ithrow): Use the correct variable when checking to
2184 see if a given element of scm_dynwinds is a valid catch.
2186 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2187 structure, abort; don't just silently ignore the garbage.
2189 * _scm.h: #include "print.h" here, since it seems to be used just
2191 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2192 strports.c, unif.h: Don't #include "print.h".
2194 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2196 * feature.h (scm_loc_features): Removed external declaration.
2197 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2199 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2201 * feature.c (scm_init_feature): Added threads feature (needs to be
2202 initialized here, since features doesn't exist when
2203 scm_init_threads is called).
2205 * libguile.h: Added #include "libguile/../threads/threads.h".
2206 (This is a kludge to get thread support working. This should be
2209 * configure.in, acconfig.h: Added flags for thread support.
2211 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2214 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2215 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2218 * _scm.h: Added conditional #include "threads.h"
2220 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2221 SCM_THREADS_SWITCHING_CODE.
2223 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2224 allocate the basic dynamic root object.
2225 (scm_boot_guile): Added call to scm_init_root.
2227 * root.c, root.h: Added root smob.
2228 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2229 functions: Implements dynamic roots mostly according to spec in
2230 SCM manual. Main difference is that the second argument is a
2231 throw handler rather than an error "thunk".
2233 * root.h: Added declaration of scm_init_root.
2235 * root.c: Added #include "genio.h", #include "smob.h", #include
2236 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2238 (scm_init_root): Added #include "root.x".
2240 * throw.c: Added #include "stackchk.h"
2241 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2242 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2243 can be used in scm_call_with_new_root; Added reenabling of stack
2244 checking when catching a throw.
2246 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2248 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2250 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2251 element is not found, as per R4RS.
2253 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2255 * list.c: Doc fixes throughout.
2257 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2259 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2260 declare the char * to be const. Avoids a warning in rgx.c.
2262 * ports.h: spelling fix.
2264 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2267 * load.c (scm_sys_try_load_path): throw an error if file not found
2268 (like it says it in NEWS).
2270 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2272 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2273 PROPS slot to '(), not #f; it's an empty alist.
2275 * throw.h, throw.c: Use SCM_P instead of #if hair.
2277 Remove special support for uncaught throws; see throw.c for
2279 * throw.c (uncaught_throw): New function.
2280 (scm_ithrow): Call uncaught_throw if we don't find a throw
2281 target; don't mess with scm_bad_throw_vcell.
2282 (scm_bad_throw_vcell): Variable deleted.
2283 (scm_init_throw): Don't initialize it.
2285 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2288 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2290 * numbers.c (scm_istr2int): If the number is short (as most
2291 numbers are), just call scm_small_istr2int to deal with it.
2292 (scm_small_istr2int): New function, created by un-#ifdefing the
2293 non-bignum version of scm_istr2int and renaming it.
2295 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2297 * load.c (scm_sys_try_load): don't check whether value returned
2298 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2299 Change the Scheme name from %try-load to primitive-load.
2301 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2302 Can avoid passing a message, allowing it to be derived in the
2303 error handler (e.g., if we want to throw to the key both from
2306 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2308 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2309 references now have a new appearance which is more compact and
2310 also gives a clue about what the target of the reference is.
2311 By setting parameters in the print state, more fancy printing can
2312 be achieved. This is used by the (not yet commited) backtrace
2315 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2317 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2320 * print.c: Added #include "struct.h". Removed function
2323 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2324 scm_iprin1. Removed prototype for scm_prlist.
2326 * arbiters.c (prinarb),
2327 async.c (print_async),
2328 debug.c (prindebugobj, prinmemoized),
2329 eval.c (prinprom, prinmacro),
2330 filesys.c (scm_fd_print, scm_dir_print),
2332 mallocs.c (prinmalloc),
2333 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2334 smob.h (scm_smobfuns),
2335 srcprop.c (prinsrcprops),
2337 unif.c, unif.h (scm_raprin1, rapr1),
2338 variable.c (prin_var): Changed argument `int writing' to
2339 `scm_print_state *pstate'.
2341 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2342 that it will be called before scm_init_print.
2344 * print.c (scm_prin1): Print states are now allocated when calling
2345 scm_prin1 and then passed around to all printing functions as an
2346 argument. A cache `print_state_pool' enables reuse of print
2348 (scm_make_print_state): New function.
2349 (scm_iprin1): Adaption to print states.
2350 (scm_iprlist): An initial "hare and tortoise" scan brings down
2351 time complexity to O (depth * N). (Better time complexity will be
2352 achieved when the printing code is completely rewritten.)
2354 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2356 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
2357 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
2358 it gets done whether or not the cache variable has a value.
2360 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2362 Distinguish #f and ().
2363 * __scm.h: #undef SICP.
2364 * pairs.h (SCM_EOL): Delete this definition, equating it with
2366 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2367 the value it used to have. Doc fixes, too.
2369 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2371 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2372 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2373 Lord's implementation of structs, allowing for tail arrays as
2374 described in the manual. Also fixed some bugs. (Both the interface
2375 and the implementation should be improved.)
2377 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2379 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2380 People who whish to see the source can do `(print-enable 'source)'.
2381 Removed #ifdef DEBUG_EXTENSIONS.
2383 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2385 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2386 integer (assuming for now accepting an integer is a good thing).
2388 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2389 %S will be used instead for write'ing arguments.
2391 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2392 asserts. fix a few other asserts.
2393 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2394 scm_uniform_vector_ref, scm_array_set_x,
2395 scm_dimensions_to_unform_array): change args in
2396 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2397 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2398 scm_substring_fill_x): likewise.
2399 gsubr.c (scm_gsubr_apply): likewise.
2400 eval.c (SCM_APPLY): likewise.
2402 * eval.c (4 places): replace scm_everr with lgh_error or
2405 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2406 scm_memory_error): new procedures.
2407 scm_everr: deleted. can use scm_wta, dropping first two args.
2408 scm_error: convert NULL subr to SCM_BOOL_F.
2410 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2413 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2416 * error.c, error.h: new error keys: scm_arg_type_key,
2417 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2419 scm_wta: reimplement using lgh_error instead of scm_everr.
2421 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2423 * gdbint.c: scm_lread now has one more argument.
2425 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2426 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2427 loading source from non-file ports, which, e. g., happens when
2428 using the Emacs interface).
2430 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2433 * read.c: Added code for recording of positions of source code
2434 expressions; New functions: recsexpr, scm_lreadrecparen;
2435 _scm_make_srcprops --> scm_make_srcprops
2436 (scm_flush_ws): Removed updating of positions counters. This work
2437 is already done by scm_gen_getc
2439 * read.h: Added prototype for scm_lreadrecparen
2441 * print.c: Added #include "alist.h"
2443 * eval.c: Added #include "hash.h"
2445 * eq.c: Added #include "ramap.h"
2447 * options.c: Documentation fixes.
2449 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
2450 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2451 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2452 --> scm_make_srcprops
2454 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2455 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2456 function calls in the definition of the whash access macros.
2458 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2460 * init.c (scm_boot_guile): Add level of indirection to
2461 scm_boot_guile_1() to ensure that stack base pointer is properly
2462 initialized. There was no guarantee that variable i was the
2463 highest/lowest variable on stack (i.e. the call frame of
2464 scm_boot_guile was not completely protected from gc).
2466 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2468 * ports.h (scm_port_table): put back file_name, it will be used to
2469 support debugging. Undo related changes in fports.c, ioext.c,
2472 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2474 * ports.h (scm_port_table): remove file_name member for now, it seems
2476 * fports.c (scm_open_file): don't set file_name in PTAB.
2477 (prinfport): don't use file_name in PTAB.
2478 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2479 * ports.c (scm_add_to_port_table): don't intialize file_name.
2480 (scm_port_file_name): remove for now.
2481 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2483 * fports.h (scm_mkfile): prototype deleted.
2484 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2486 * debug.c, unif.c: use scm_out_of_range instead of
2487 wta for range errors (ASSERT still needs work).
2489 * error.c, error.h (scm_out_of_range): new procedure.
2491 * error.c, error.h (scm_out_of_range_key): new key.
2493 * posix.c (scm_sync): #else was missing.
2495 * error.c, error.h: append _key to names scm_num_overflow and
2498 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2499 of consing an empty list.
2500 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2501 of macros, saves code and string space.
2502 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2503 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2504 lower case. Rename scm_syserror_m to scm_syserror_msg.
2505 error.h: prototypes for new procedures.
2507 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2509 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2511 * error.c, error.h: setup scm_num_overflow key.
2513 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2514 Remove definition of SCM_OVSCM_FLOW.
2516 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2518 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2519 explicit message and args.
2521 * error.c, error.h, __scm.h: change system_error_sym to
2524 * error.c (system_error_sym): remove leading %% from the Scheme name
2527 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2529 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2531 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2532 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2533 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2534 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2535 renamed. (These were introduced by unsupervised name
2538 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2540 * print.c: Added code for detection of circular references during
2541 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2542 a hook for printing of closures (accessible via print options).
2543 This leads to a split of calls to scm_iprin1 into two classes:
2544 elementary print operations (e. g. the code which prints a smob)
2545 still use scm_iprin1 while top level calls (like scm_display) use
2546 scm_prin1. scm_prin1 begins by clearing the data structure used
2547 to record reference information.
2549 * print.h: Added declarations of scm_prin1 and scm_prlist.
2551 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2553 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2555 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2557 * error.c (err_head): scm_iprin1 --> scm_prin1
2559 * debug.c: Adjusted header comment.
2563 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2565 * strerror.c: Doc fix.
2567 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2569 * gdbint.c (gdb_read): Now possible to run during GC.
2570 (unmark_port, remark_port): New functions.
2572 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2574 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2575 of allocating a new string object. Also, increase size by
2576 the factor 2 instead of 1.5.
2578 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2580 * __scm.h (SCM_P): Corrected to run under traditional C.
2582 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2585 * async.c: Calls to scm_sysintern corrected.
2587 * async.h (scm_async_clock): Redundant declaration removed.
2589 * continuations.c (scm_dynthrow): Redundant declaration removed.
2591 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2592 Definition typos corrected.
2594 * debug.h: Missing declarations of functions in debug.c added
2597 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2598 Missing declarations to functions in eval.c added.
2600 * filesys.c: Possibly uninitialized variable rv.
2602 * gc.h (scm_object_addr, scm_unhash_name): Missing
2603 declarations of functions defined in gc.c added.
2605 * genio.c: Possible typos str_data -> wstr_data. ???
2607 * genio.c: Possibly unintended shadowing of local variable
2608 `int c' (gotos out of scope of inner `c'). ???
2610 * init.c: Uninitialized `SCM last' may be used.
2612 * ioext.h: (scm_sys_isatty_p): Typo.
2614 * list.h (scm_list_head): Missing prototype for function in
2617 * numbers.c (scm_two_doubles): Changed from extern to static
2618 (is used only within numbers.c).
2620 * numbers.h: Repeated declarations removed.
2622 * ports.h (scm_close_all_ports_except): Declaration for the
2623 function defined in ports.c added.
2625 * posix.h: Missing declarations added.
2627 * procs.h (scm_make_subr_opt): Missing declaration added.
2629 * socket.h (scm_sys_gethost): Missing declaration added.
2631 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2633 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2634 Missing declarations added.
2636 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2638 * struct.c: Uninitialized variable `SCM answer' may be used.
2640 * unif.c (l2ra): Declaration prototype.
2642 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2643 defined in ramap.c).
2645 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2646 Redundant declarations removed (they are in ramap.h).
2648 * variable.h (scm_make_udvariable,
2649 scm_make_undefined_variable): Declaration corrected to
2650 correspond variable.c.
2652 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2653 Missing declarations added.
2655 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2657 * Makefile.in (distclean): Don't forget to delete fd.h.
2659 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2661 * fd.h.in, tags.h: Trivial cleanups.
2663 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2664 marksweep.h just declared functions from gc.c.
2665 * gc.h, libguile.h: Don't #include "marksweep.h".
2666 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2667 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2668 dependencies updated.
2670 * libguile.h: Don't #include "files.h"; it's been deleted.
2672 * files.c (scm_sys_delete_file): Moved to filesys.c.
2673 File is now empty; deleted.
2675 * filesys.c: scm_sys_delete_file is now here. Remove
2676 #if's; they seem to rely on remnants of an old portability
2677 regimen. If the problems come up again, solve them properly,
2678 using autoconf. Specifically: Don't test M_SYSV, and #define
2679 remove to be unlink if it's #defined; don't use remove just
2680 because HAVE_STDC_HEADERS is #defined.
2681 * filesys.h: Add declarations for scm_sys_delete_file.
2682 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2683 files.o, files.h, files.c, and files.x.
2684 * init.c: Don't #include "files.h", and don't call scm_init_files.
2686 Use SCM_P instead of PROTO; the latter intrudes on the user's
2688 * params.h: Deleted; definition of SCM_P moved to...
2689 * __scm.h: ... here, where it replaces PROTO macro.
2690 * libguile.h, smob.h: Don't #include "params.h".
2691 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2692 smob.h: Fix prototypes accordingly.
2693 * Makefile.in: Update dependencies.
2694 (inner_h_files): Remove params.h.
2696 * gc.c: #include "gc.h"; every module should include its header,
2697 to let the compiler cross-check the declarations against the
2700 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2701 simpos.h: #include "libguile/__scm.h".
2703 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2705 * init.c: Don't forget to #include smob.h and init.h.
2706 * Makefile.in: Dependencies updated.
2708 * smob.h: Use PROTO instead of #if __STDC__.
2710 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2712 * __scm.h: Doc fixes.
2714 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2715 <angles>; this allows `make depends' to work properly.
2717 * libguile.h: #include smob.h and pairs.h before the others; they
2718 define typedefs used by other headers.
2720 C files should #include only the header files they need, not
2721 libguile.h (which #includes all the header files); the pointless
2722 recompilation was wasting my time.
2723 * Makefile.in (all .o dependency lists): Regenerated.
2724 * libguile.h: Don't try to get a definition for size_t here...
2725 * __scm.h: Do it here.
2726 * _scm.h: Since this is the internal libguile header, put things
2727 here that all (or a majority) of the libguile files will want.
2728 Don't #include <libguile.h> here; that generates dependencies on
2729 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2730 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2731 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2828 * weaks.c: Get "weaks.h".
2830 * stackchk.h: #include "libguile/debug.h",
2832 * print.h, read.h: #include "options.h", since everyone who uses
2833 either of these files will need that.
2835 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2836 anyone who uses this file will need them to define the smob
2837 printing functions. Also, get markers.h, since people will need
2838 to #define the mark functions.
2840 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2841 * ports.h: ... to here.
2843 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2844 don't rely on archaic C default type rules.
2846 * fports.h: #include "libguile/ports.h", since you need that in
2847 order to parse this.
2849 * genio.h: #include "libguile/print.h", because you need that to
2850 parse this; don't bother #including "ports.h", since print.h gets
2853 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2855 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2856 this; it's now a reference to an element of *scm_root.
2858 * debug.h: Don't #include "options.h"; the compiler won't be able
2859 to find that once the headers are installed; instead, #include
2860 "libguile/options.h".
2861 * gc.h: Same, with marksweep.h.
2862 * mbstrings.h: Same, with symbols.h.
2863 * scmhob.h: Same, with _scm.h.
2864 * smob.h: Same, with params.h.
2866 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2867 C files; there's no need for this, and it forces recompilations
2870 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2872 * error.c (scm_error): declare scm_error_callback.
2874 * error.h: prototype for scm_error_callback.
2876 * __scm.h: define lgh_error.
2877 (SCM_SYSERROR): redefine using lgh_error.

2881 * error.c (scm_error): new procedure.
2883 * error.h: prototype for scm_error.
2885 * Makefile.in (install): install scmconfig.h from the current
2886 directory, not $(srcdir).
2888 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2890 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2891 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2892 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2893 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
2894 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
2895 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2896 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2897 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2898 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2899 vports.h, weaks.h: #include "libguile/__scm.h", not
2900 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2901 dependencies are within libguile properly.
2903 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2905 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2906 when scmconfig.h doesn't exist.
2908 * load.c (scm_sys_try_load): Correct spelling.
2910 * feature.c (scm_loc_features): Make this static.
2912 * Makefile.in (libpath.h): Omit trailing slash from path. We
2913 shouldn't require it of users, so why put it here?
2915 Move code to initialize and search %load-path from ice-9 to C
2916 code, so we can use the load-path to find the ice-9 boot code;
2917 this makes it easier to run Guile without installing it. See
2918 corresponding changes in guile/Makefile.in.
2919 * feature.c: Move stuff concerned with the load path to load.c.
2920 (scm_compiled_library_path): Deleted.
2921 Don't #include libpath.h here.
2922 * feature.h: Don't mention scm_compiled_library_path.
2923 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2924 <sys/stat.h>, and <unistd.h> (if present).
2925 (R_OK): #define if the system hasn't deigned to.
2926 (scm_loc_load_path): New variable.
2927 (scm_init_load_path, scm_sys_search_load_path,
2928 scm_sys_try_load_path): New functions.
2929 (scm_init_load): Initialize scm_loc_load_path to point to the
2930 value cell of the Scheme %load-path variable.
2931 * load.h: Add declarations for scm_sys_search_load_path,
2932 scm_sys_try_load_path.
2933 * init.c: Call scm_init_load_path.
2934 * Makefile.in (feature.o, load.o): Dependencies updated.
2936 * load.c, load.h: Rewrite using PROTO macro.
2938 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2940 * gc.c (scm_cellp): New function: C predicate to determine if an
2941 SCM value can be regarded as a pointer to a cell on the heap.
2943 * gc.h: Added declaration of scm_cellp.
2945 * gdb_interface.h: New file: The GDB interface header from the GDB
2948 * gdbint.c: New file: GDB interface.
2950 * gdbint.h: New file: GDB interface.
2952 * libguile.h: Added #include <libguile/gdbint.h>.
2954 * init.c (scm_boot_guile): Added scm_init_gdbint.
2956 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2957 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2958 found if object files and source are kept separate).
2960 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2962 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2964 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2966 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2967 TK_SRC_DIR; they're not relevant any more.
2969 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2970 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2972 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2974 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2975 search path, so we can find the <libguile/MUMBLE.h> headers.
2977 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2979 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2980 implicit in the .c.o rule.
2981 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2984 Put the library path in a header file, instead of passing it on
2985 the command line in every compilation.
2986 * Makefile.in (libpath.h): New target.
2987 (feature.o): Depend on libpath.h.
2988 (clean): Delete libpath.h.
2989 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2990 * feature.c: ... #include "libpath.h" here.
2991 * .cvsignore: Ignore libpath.h.
2993 Don't install the unwashed masses of Guile header files in the
2994 main #include path; put most of them in a subdirectory called
2995 'libguile'. This avoids naming conflicts between Guile header
2996 files and system header files (of which there were a few).
2997 * Makefile.in (pkgincludedir): Deleted.
2998 (innerincludedir): New variable; this and $(includedir) are enough.
2999 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
3000 (installed_h_files): Divide this up. Now this variable lists
3001 those header files which should go into $(includedir) (i.e. appear
3002 directly in the #include path), and ...
3003 (inner_h_files): ... this new variable says which files appear in
3004 a subdirectory, and are referred to as <libguile/mumble.h>.
3005 (h_files): List them both.
3006 (install): Create innerincludedir, not pkgincludedir. Put
3007 the installed_h_files and inner_h_files in their proper places.
3008 (uninstall): Corresponding changes.
3009 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3010 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3011 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
3012 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
3013 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
3014 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3015 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3016 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3017 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3018 vports.h, weaks.h: Find __scm.h in its new location.
3019 * __scm.h: Find scmconfig.h and tags.h in their new locations
3020 (they're both "inner" files).
3022 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
3024 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
3026 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3028 * posix.c: Doc fixes.
3030 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
3032 * socket.c: Don't include a prototype for inet_aton; just use a
3033 K&R style declaration, to avoid warnings but minimize the chance
3034 of conflicts with the system.
3036 On NextStep, <utime.h> doesn't define struct utime, unless we
3037 #define _POSIX_SOURCE before #including it.
3038 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
3039 * acconfig.h: New comment text for above CPP symbol.
3040 * configure.in: Call it.
3041 * posix.c: #define _POSIX_SOURCE if it seems necessary.
3043 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
3045 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
3046 testing for __EMX__.
3048 * posix.c: #include <libc.h>, if it exists.
3050 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
3051 don't even know if the latter exists.
3053 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
3054 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
3055 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
3057 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
3059 (scm_init_posix): Use them when initializing the Scheme constants
3062 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3064 * Makefile.in (libdir, includedir, bindir): Use the
3065 autoconf-supplied values, instead of deriving them ourselves.
3066 (pkgincludedir, datadir, pkgdatadir): New variables.
3067 (install, uninstall): Put the header files in a special
3068 subdirectory, not in the main search path.
3070 * Makefile.in (ALL_CFLAGS): Provide the proper value for
3071 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
3073 * Makefile.in (IMPLPATH): Deleted; never used.
3075 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
3076 on the Tcl/Tk source any more.
3077 (INCLUDE_CFLAGS): Remove references to the above.
3079 * Makefile.in (version.o): Corrected dependencies.
3081 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
3083 * libguile.h: #include "version.h"
3085 * init.c (scm_boot_guile): Call scm_init_version.
3086 * gscm.c (gscm_run_scm): Call scm_init_version.
3088 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
3089 GUILE_VERSION): AC_DEFINE these.
3090 (acconfig.h): #undef the above symbols.
3092 * Makefile.in (libobjs): Add version.o.
3093 (installed_h_files): Add version.h.
3094 (c_files): Add version.c.
3095 (gen_c_files): Add version.x.
3096 (version.o): New rule.
3097 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
3098 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
3099 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
3100 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
3101 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
3102 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
3103 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
3104 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
3105 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
3106 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
3107 weaks.o): Add version.h to dependency lists.
3108 (markers.o): Remove duplicate rule.
3110 * version.h: New file.
3112 * version.c: New file.
3114 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3116 * symbols.c (scm_strhash): scm_downcase is now a function, not an
3117 array; use it appropriately. Since GCC is quite happy to
3118 subscript functions, it never warned us about this; we should use
3119 -Wpointer-arith in the future. I guess we never tested
3122 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3124 * socket.c: Doc and copyright fixes.
3126 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3128 * debug.c: Fixed and improved gdb support.
3130 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3132 * socket.c: Added declaration of inet_aton to avoid compiler
3133 warning. (Hope this solution is correct.)
3135 * stime.c: Added declaration of ftime. (This is missing in
3138 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
3140 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3142 * Makefile.in (c_files): add strerror.c.
3144 * strerror.c: new file from Emacs' sysdep.c.
3145 maybe configure should also check for sys_errlist.
3147 * configure.in (AC_REPLACE_FUNCS): add strerror.
3149 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3151 * debug.c (scm_init_debug): Added initialization for
3152 scm_evaluator_traps.
3154 * debug.h, debug.c: Various name changes.
3155 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
3156 "debug-options-interface". See commentary in options.c.
3158 * options.h, options.c: Options now have documentation strings.
3159 Also added a long explanatory commentary.
3161 * eval.c, print.h, print.c, read.h, read.c: Modifications to
3164 * gscm.c, init.c, root.c, throw.c: Bug fixes:
3165 last_debug_info_frame is now updated in all cases.
3167 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
3170 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3172 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
3173 Added option STACK_CHECKING.
3175 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3177 * Makefile.in: Added {debug,options,srcprop}.{h,c}
3179 * __scm.h: Removed symbols for debugging support.
3181 * acconfig.h: Added symbols for debugging support.
3183 * configure.in: Added user option for debugging support.
3184 --enable-debug will include the debugging code into libguile.a.
3186 * continuations.c (scm_make_cont): Enlarged the #if 0 around
3187 scm_relocate_chunk_to_heap.
3189 * debug.c: New file: low-level debugging support. It also
3190 includes support for debugging with gdb. (The extensions to gdb
3191 are written by Per Bothner at Cygnus.)
3193 * debug.h: New file: low-level debugging support.
3195 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
3196 argument pairs. Extensive modifications to the debugging
3197 evaluator. Added "SECTION:" commentaries to clarify what happens
3198 when, during double compilation. Renamed EVALIMP --> EVALIM.
3199 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
3200 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
3201 the beginning of the file. New procedure: scm_unmemocopy.
3202 Added some global state variables needed by the debugging
3203 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3204 check_entry, check_apply, check_exit, debug_options and
3205 evaluator_traps. New acro: undefine.
3207 * eval.h: Renamed EVAL --> XEVAL.
3209 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3210 --> scm_make_weak_key_hash_table.
3212 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3213 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3215 * libguile.h: Conditionally include debug.h
3217 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3218 scm_object_properties shouldn't return handle. `handle' now gets
3219 initialized in scm_set_object_properties_x. scm_object_properties
3220 doesn't any longer create an entry in scm_object_whash.
3222 * options.c: New file: handling of run time options.
3224 * options.h: New file: handling of run time options.
3226 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
3228 * print.c: New procedure: scm_print_options
3230 * print.h: Defines for print options.
3232 * read.c: New procedure: scm_read_options
3234 * read.h: Defines for reader options.
3236 * root.h: Added scm_source_whash among scm_sys_protects.
3238 * srcprop.c: New file: source properties.
3240 * srcprop.h: New file: source properties.
3242 * throw.c (jbsmob): Jump buffers are now correctly allocated.
3243 (Bug found by A. Green.)
3245 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3247 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3249 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3251 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3253 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3254 and should be called by the final client.
3256 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3258 * gc.h: Use the PROTO macro when declaring functions.
3259 * gc.c: Use the PROTO macro when declaring static functions.
3260 Remove the CPP hair around function definitions.
3262 * gc.c (scm_init_storage): Initialize scm_asyncs.
3264 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3265 preprocessor symbol; "__scm.h" is where it might get #defined.
3266 * __scm.h: Similar: #include <scmconfig.h> before testing
3269 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3271 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3273 * init.c (scm_boot_guile): Add init_func argument; call
3274 (*init_func) instead of calling scm_appinit; it's ucky to
3275 hard-code names for the user's procedures.
3276 * init.h (scm_boot_guile): Adjust declaration.
3278 * __scm.h (PROTO): New macro, for declaring functions with
3281 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3282 eliminate all the __STDC__ conditionals.
3283 (scm_boot_guile): Add declaration.
3284 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3285 Remove __STDC__ conditionals around function definitions; the
3286 declarations in init.h will provide the same information, more
3289 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3290 complain about it in the error message; the error message is
3291 adequate without that note, and there's nothing the user can do
3294 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3296 * Makefile.in (ancillary): Drop def.sed.
3298 * posix.c (scm_init_posix): Use numeric values, rather than
3299 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3300 F_OK. The symbols aren't available on some systems, and I'm
3301 pretty sure their values are fixed by common widespread practice.
3302 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3304 More functions unavailable on some systems.
3305 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3306 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3308 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3309 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3310 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3311 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3312 stub that signals an error as the #else.
3314 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
3316 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
3318 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
3320 * unif.c: include ramap.h.
3322 * read.c (endif): case_insensative_p renamed case_insensitive_p.
3324 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
3326 * ports.c: include sys/ioctl.h.
3328 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
3330 * configure.in: check for sys/ioctl.h.
3332 * ports.c: include <malloc.h> not "malloc.h".
3334 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3336 * fports.c: remove ttyname and tmpnam declarations.
3338 * posix.c: fewer ttyname declarations.
3340 * fports.c: include <string.h> not "string.h".
3342 * init.c, ioext.c: include string.h and unistd.h.
3344 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3346 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
3347 genio.c, simpos.c, vports.c: include string.h.
3349 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
3351 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
3353 (scm_addr_buffer_size): change type from scm_sizet to int.
3354 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
3355 from scm_sizet to int.
3357 * error.c: include unistd.h.
3359 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
3362 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
3364 * __scm.hd, def.sed: deleted.
3366 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
3368 Changes for NeXT, suggested by Robert Brown.
3369 * configure.in: Call AC_TYPE_MODE_T.
3370 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
3371 NeXT. Put header file list in alphabetical order.
3372 * configure, scmconfig.h.in: Regenerated.
3373 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
3375 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
3378 * acconfig.h: New file, providing documentation for the CPP
3379 symbols defined in configure.in
3380 * acconfig-1.5.h: Removed; superceded by the above.
3382 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
3384 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
3386 * fports.c (scm_open_file): don't return #f, throw error.
3388 * ioext.c (fileno): renamed from %fileno.
3389 (soft-fileno): deleted.
3391 * ports.c (scm_port_revealed): don't need to check for -1 from
3393 (scm_set_port_revealed_x): return unspecified, not #f.
3395 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3397 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3399 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3401 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3403 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3405 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3406 This is necessary on Ultrix, and doesn't hurt portability.
3408 * Makefile.in (dist-dir): New target, implementing a new dist system.
3409 (installed_h_files): Put in alphabetical order.
3410 Remove duplicate entries for markers.h and unif.h.
3411 (c_files): Remove duplicate entries for markers.c.
3412 (ancillary): Renamed from anillery; all uses changed. Remove
3413 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3414 Remove all the ../doc/* files; doc/Makefile.in handles that.
3416 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3418 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3419 every if must have an else, or else the whole command has a
3420 non-zero exit code whenever the if's condition is false.
3422 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
3424 * posix.c: include string.h.

3437 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
3439 * struct.c (scm_init_struct): new file.
3441 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>

3484 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
3486 * ports.c (scm_ports_prehistory): size malloced here doesn't
3487 matter so long as it is non-0 (got rid of "* 4").
3489 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3491 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3492 since its definition was bogus).
3494 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3496 * mallocs.[ch]: back again (for rx at least).
3498 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3500 * ports.c: removed functions relating to the mapping between ports
3501 and descriptors. (That stuff is unix-specific and should be collected
3502 in a separate library).
3504 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
3505 (Tom Mckay@avanticorp.com)

3509 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3510 handled correctly (SCM_FREEP was applied to them) -- test for
3511 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
3512 being overwritten with #f. (brown@grettir.bibliotech.com)

3566 * ports.c (scm_add_to_port_table): Added fields
3567 to port table entries: file_name, line_num, col.

3679 initialization to fix a race condition.
3681 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

3705 set the multi_byte flag correctly in symbols. This is wrong.
3706 intern_obbary_soft and msymbolize should take an extra parameter.
3707 Also, weird multibyte symbols don't print correctly.
3708 The weird symbol syntax is also a bit bogus (emacs doesn't quite
