1 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
3 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4 feature, to help boot-9.scm decide whether to import the regex
7 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
9 * eval.c: Include scmconfig.h at the beginning of the file so that
10 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
13 * regex-posix.c: #include "_scm.h" before conditionally #including
14 <regex.h>; the former defines HAVE_REGCOMP.
16 * regex-posix.c: #include <regex.h> conditionally, so the file is
17 CPP'able (for dependency scanning) even on systems that don't have
20 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
22 Add new R4RS-compliant syntax for keywords.
23 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
24 regardless of the setting of the `keywords' read option.
25 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
26 can be re-read no matter what the setting of the `keywords' read
29 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
31 Add support for POSIX regular expressions.
33 * regex-posix.c, regex-posix.h: New files. (Some code
34 is taken liberally from rx/rgx.c in the old Guile dist.)
36 * init.c: Include regex-posix.h.
37 (scm_boot_guile_1): Call scm_init_regex_posix.
39 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
40 Add regex-posix.[ch] sources.
41 * Makefile.in: Regenerated.
43 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
44 to do this automatically? It didn't for me, bleh.)
46 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
48 * fports.c (print_pipe_port): New function.
49 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
50 latter doesn't even take the right arguments.
52 * Makefile.am: Increment shared lib revision number. I think
53 sometimes the uninstalled Guile finds the installed shared lib;
54 Gord says doing this might help. As things turned out, I can't
56 * Makefile.in: Regenerated.
58 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
59 passing it as the closure argument to scm_boot_guile. (Bill
62 * ports.c (print_void_port, putc_void_port, puts_void_port,
63 write_void_port, flush_void_port, getc_void_port, close_void_port,
64 noop0): Use ANSI prototypes instead of K&R declarations, so the
65 initialization of void_port_ptob gets aggressively type-checked.
66 Fix arguments of print_void_port and write_void_port. (Bill

100 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
102 * script.c (scm_find_executable): Use prototype-style definition
103 here; apparently it's not quite right to have const in a prototype
104 and then use a K&R declaration. I wonder if stuff like this will
105 go away if we compile with -Wrequire-prototypes, or whatever that
106 is... (Bernard URBAN)
108 * scmhob.h: New text from Bernard URBAN.
110 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
112 * script.c: Don't #define const on hpux. Configure takes care of
113 this. (Thanks to Larry Schwimmer.)
115 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
116 decide whether to #include <unistd.h>, instead of listing a bunch
117 of systems. Don't #include stdio twice. Removed dyked-out
118 definition of scm_find_impl_file.
120 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
122 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
123 library version info to 1:0.
124 * Makefile.in: Regenerated.

130 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
131 throw.c: Update copyright years; these files have been worked on
132 significantly in 1997, but only had copyright years for 1996.
133 Also, change name of copyright holder on some from Mikael
134 Djurfeldt to Free Software Foundation; he has signed papers
135 assigning the changes to the FSF.
137 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
138 reason not to give the user the option.
140 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
141 Return #f on end-of-file when scanning table (i.e. when called
142 with no arguments). Try to catch errors, when we can.
143 * posix.c (scm_getgrgid, scm_getpwuid): Same.
145 * script.h (scm_shell_usage, scm_compile_shell_switches): New
146 external declarations. These are useful.
148 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
150 * posix.c: don't include <sys/select.h> or define macros for
151 select, since they were not used in this file.
153 * filesys.c (scm_select): make the fifth parameter microseconds,
154 not milliseconds. let the fourth parameter be either a real value
155 or an integer or #f. The first, second and third arguments can
156 now be vectors: the type of the corresponding return set will be
158 (set_element, get_element): new static procedures.
160 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
162 * strports.c (scm_eval_string): New function.
163 (scm_eval_0str): Trivially re-implemented in terms of
165 * strports.h (scm_eval_string): New extern decl.
167 * net_db.c (h_errno): Add extern decl for this.
169 * fports.c (local_pclose): New function.
170 (scm_pipob): Use it in the initializer here.
173 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
174 Use a meaningful error message when signalling an error. For
175 this, scm_gethost must check h_errno rather than errno.
177 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
179 * Makefile.in: Regenerated, using automake-1.1p.
181 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
183 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
186 * script.c (scm_compile_shell_switches): don't append (quit) if
188 (scm_shell): call scm_exit_status and exit on the result of the
191 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
193 Ensure that shared substrings are handled properly when passed to
194 a system call or other foreign function. Many thanks to Tim
196 * symbols.h (SCM_COERCE_SUBSTR): new macro.
197 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
198 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
199 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
200 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
201 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
202 (scm_display_error_message): use RO macros when strings may be RO.
203 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
204 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
205 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

209 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
210 scm_strftime), vports.c (scm_make_soft_port): use
211 SCM_COERCE_SUBSTR to make sure shared substrings are
214 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
216 * error.c (scm_error): Add newline to error message.
218 * init.c (scm_init_standard_ports): Doc fix.
220 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
222 * dynl-shl.c: Completely replaced with new code from Bernard
225 * script.c (scm_ice_9_already_loaded): New variable.
226 (scm_compile_shell_switches): Use it.
228 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
230 * filesys.c (scm_input_waiting_p): add missing third argument to
233 * stime.c (scm_localtime): copy the result of localtime before
234 calling gmtime in case they share a buffer.
235 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
238 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
240 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
242 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
244 * Makefile.am (check-local): New target, which causes 'make check'
245 to run gh_test_c and gh_test_repl, with some trivial input.
246 * Makefile.in: Rgnrtd.
248 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
250 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
253 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
255 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
256 sure how this was supposed to work.
257 (scm_async_click): don't send SCM_TICK_SIGNAL.
258 (scm_init_async): don't initialize %tick-thunk.
260 * the following change doesn't affect the Scheme interface:
261 gc-thunk is called at the end of garbage collection. however it's
262 no longer implemented by pretending it's a signal.
264 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
265 system async corresponding to scm_gc_thunk.
266 * async.h: declare scm_gc_async.
267 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
268 gc-thunk directly, instead of going through a signal handler.
269 (scm_gc_async): new variable, points to the GC system-async.
270 (scm_init_async): save the GC async as scm_gc_async instead
271 of using system_signal_asyncs.
272 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
274 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
276 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
277 Don't screw up if we're interrupted.
278 * Makefile.in: Regeneradet.
280 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
282 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
284 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
285 we're not using AM_INIT_GUILE_MODULE any more.
286 * Makefile.in: Reneregated.
288 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
290 Functions for finding variable bindings, grace à Tim Pierce.
291 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
292 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
294 Get 'make dist' to work again.
295 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
296 * Makefile.in: Regenerated, like a surry without a fringe on top.
298 Changes for reduced Guile distribution: one configure script,
300 * configure.in, configure: Removed.
301 * acconfig.h, acinclude.m4: Moved to parent directory, where the
302 real configure script lives.
303 * Makefile.in, scmconfig.h.in: Regenerated.
305 * init.c: #include "script.h", to get prototype for script.c's
308 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
310 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
311 scm_must_malloc, not raw malloc.
313 * script.c (scm_compile_shell_switches): Dyke out debugging output
316 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
318 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
320 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
321 system has them. Hope this is safe. Previously
322 sys/timeb.h was included if HAVE_FTIME was defined or if
323 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
324 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
326 * ioext.c (scm_setfileno): add missing third argument to
329 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
331 * eq.c (scm_equal_p): Correctly compare strings of different
332 varieties. (Thanks to Tim Pierce.)
334 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
336 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
337 #! block comment must occur on a line all by itself.
339 Move most of the guts of shell command processing into libguile,
340 so guile.c can be very small (and eventuallly auto-generated. (I
341 mean, generated mechanically, not self-generated. Hmm.))
342 * guile.c, script.c, script.h: New source files.
343 * init.c (scm_boot_guile_1): Call scm_init_script.
344 * libguile.h: #include "script.h".
345 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
346 targets, for new executable.
347 (libguile_la_SOURCES): Mention script.c.
348 (modinclude_HEADERS): Add script.h.
349 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
350 not dynamic linking is enabled. This is because we're generating
351 executables now. Move CY_AC_WITH_THREADS call after those, so the
352 values of cy_cv_threads_libs captures the libs chosen above.
353 * Makefile.in, configure, aclocal.m4: Regenerated.
355 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
356 We don't maintain this interface any more, and it just confuses
359 * alloca.c: #include <scmconfig.h>, not <config.h>.
360 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
361 it'll get included in disties.
363 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
365 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
366 be distributed, because they confuse people.
367 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
369 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
371 * configure.in: check for presence of gethostent (not present on
373 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
374 * configure, scmconfig.h.in: Regenerated.
376 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
378 * backtrace.c (scm_backtrace): Split message string across
379 newlines properly. GCC is more tolerant of this than other
382 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
384 Merge threads directory into libguile.
385 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
386 threads.h: New source files.
387 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
388 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
390 (modinclude_HEADERS): Add threads.h, coop-defs.h.
391 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
392 coop-threads.c.cygnus, coop-threads.h.cygnus.
393 * configure.in: If we're using threads, include threads.o in
395 * _scm.h, libguile.h: threads.h lives in this directory now.
396 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
397 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
398 currently used, but brought along for information's sake.
399 * ChangeLog-threads: log from old 'threads' directory.
400 * Makefile.in, configure: Rebuilt.
402 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
404 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
407 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
409 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
411 Merge GH interface library into libguile.
412 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
413 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
414 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
415 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
417 (EXTRA_libguile_la_SOURCES): ... here.
418 (pkginclude_HEADERS): Add variable, to get gh.h installed.
419 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
420 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
421 New variables, describing how to build the gh test programs.
422 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
423 build the test programs, and we probably should have been linking
424 libguile.la against them all along, to support AIX shared libs.
425 Add cflags for threads to CFLAGS; add libs for threads to new
426 variable THREAD_LIBS, used in Makefile.am.
427 * ChangeLog-gh: log from old `gh' subdirectory.
428 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
430 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
432 * acconfig.h: Undo change of Apr 9; including the definition of
433 PACKAGE in the guile headers conflicts with applications' own
435 * scmconfig.h.in: Regenerated.
437 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
439 * filesys.c (scm_fcntl): New function from Roland McGrath.
440 (scm_init_filesys): New symbols for use with fcntl.
441 * filesys.h: Added prototype.
443 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
444 when PROC is receiving no arguments.
446 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
448 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
449 have S_IFSOCK. This is the case under Ultrix.
451 * posix.c (scm_status_exit_val, scm_status_exit_val,
452 scm_status_term_sig, scm_status_stop_sig): Modified to work with
453 Ultrix versions of WIFSTOPPED, etc., which assume that their
454 arguments are lvalues (hmm).
456 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
460 * throw.c: Doc fixes; rearranged.
462 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
464 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
466 * acconfig.h: Added entry for PACKAGE.
467 * scmconfig.h.in: Regenerated.
469 Changes to work with automake-1.1n, which has better libtool support.
470 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
471 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
473 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
475 * Makefile.in: Rebuild.
477 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
479 * stime.c (scm_mktime): take an optional zone argument.
480 (scm_localtime): check putenv return value.

484 (bdtime2c, setzone, restorezone): new static procedures.
485 (scm_mktime, scm_strftime): use them.
486 (scm_strftime): don't call mktime before strftime. Use
487 filltime for return value.
488 (filltime): convert NULL zname to #f.
489 (scm_strptime): return a count of characters consumed, not
490 the remaining string.
492 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
494 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
495 (scm_mktime): likewise.
497 Uncomment localtime and mktime.
499 * configure.in: add AC_STRUCT_TIMEZONE.
501 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
503 * stime.c (scm_init_stime): don't define ticks/sec.
504 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
505 return value problem and is still portable.)
507 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
509 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
510 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
511 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
512 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
513 cpp_err_symbols.c): Corresponding changes.
514 * Makefile.in: Regenerated.
516 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
518 * posix.c (scm_putenv): don't check HAVE_PUTENV.
519 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
520 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
521 * putenv.c: new file, from sh-utils 1.12.
523 * posix.c (scm_environ): use malloc in place of scm_must_malloc
524 since allocation isn't for Scheme objects.
525 (scm_putenv): copy strings before placing in the environment.
527 * stime.c (scm_current_time): throw an error if time returns -1,
528 instead of returning #f.
529 (scm_get_internal_real_time, scm_get_internal_real_time): use
530 scm_long2num for return value instead of SCM_MAKINUM.
532 * stime.h: prototypes updated.
534 * stime.c (scm_time_in_msec): apparently unused, deleted.
536 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
538 * configure.in: check for gettimeofday.
540 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
541 which may be more usefully portable than a gettimeofday interface.
543 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
545 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
547 * Makefile.in: Regenerated.
549 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
551 * stime.c (filltime): recovered static procedure.
552 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
555 * posix.h: add prototype for scm_close_pipe, remove prototypes for
556 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
558 * posix.c (scm_mknod): split the mode argument into type and perms
559 arguments, like the extra fields returned by stat.
561 * fports.c (scm_pipob): set the close, free and print procedures.
562 (scm_close_pipe): new procedure.
564 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
565 define them in boot-9.scm
567 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
569 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
570 wan't defined. Don't include fd.h.
572 * Previously fd.h was regenerated whenever configure was run,
573 forcing a couple of files to be recompiled.
575 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
576 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
577 Check for _fileno as well as _file.
579 * ioext.c: don't fd.h.
580 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
583 * Change the stratigy for getting information about errno
584 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
585 generating lists of symbols during the build process, which will
586 not always work, include comprehensive lists in the distribution.
587 To help keep the lists up to date, the "check_signals" and
588 "check_errnos" make targets can be used.
590 * configure.in: don't check for a command to extract errno codes.
591 * Makefile.am: update file lists, remove errnos.list and errnos.c
592 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
593 check_errnos targets.
594 (CLEANFILES): remove errnos.c and errnos.list, add
595 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
596 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
597 * errnos.default: deleted.
598 * cpp_signal.c: new file.
599 * cpp_errno.c: renamed from errnos_get.c.
600 * cpp_err_symbols, cpp_sig_symbols: new files.
601 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
602 * error.c (scm_init_error): #include cpp_err_symbols instead of
604 * posix.c (scm_init_posix): don't intern signal symbols. #include
607 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
609 * strop.c (scm_i_index): allow the lower bound to be equal to the
610 length of the string, so a null string doesn't always give an error.
612 * posix.h: new prototypes.
613 * posix.c (scm_status_exit_val, scm_status_term_sig,
614 scm_status_stop_sig): new functions, as in scsh. They break down
615 process status values as returned by waitpid.
617 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
619 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
620 configure doesn't know about it.
622 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
624 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
626 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
627 which defines C variables with global linkage.
629 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
631 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
634 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
636 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
637 has time to check why this doesn't work well with continuations.
639 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
641 * Fix shell syntax error; some shells won't tolerate
642 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
644 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
646 * posix.c (scm_uname): throw an error if uname fails instead
649 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
651 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
654 * async.c (scm_ints_disabled): definition moved from error.c.
656 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
658 * acconfig.h: Removed PACKAGE.
660 * scmconfig.h.in: Regenerated.
662 * snarf.h: g++ says it's non-portable not to specify the first
663 argument in a varargs declaration. I introduced the first
664 argument by using preprocessor conditionals.
666 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
668 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
669 (scm_freopen): use RO string macros for filename and modes.
670 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
672 * posix.c (scm_getgrgid): simplify conversion of name to C string.
673 (scm_mknod): use RO string macros for path.
675 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
676 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
678 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
679 use SCM_ROSTRINGP and SCM_ROCHARS.
681 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
683 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
686 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
687 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
688 support for byte vectors.
690 * print.c (scm_iprin1): Limit number of vector elements printed
691 according to pstate->length.
693 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
695 * backtrace.c (scm_display_error_message): don't segv if message
698 * error.h: prototype for scm_error_scm.
700 * error.c (scm_error_scm): new procedure, reimplements scm-error
701 in C and uses scm_error.
703 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
705 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
706 pointer to the Scheme variable read-hash-procedures and intern it
707 in scm_init_read. Modify scm_read_hash_extend and
708 scm_get_hash_procedure to use the pointer.
710 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
712 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
713 (SCM_KEYWORD_STYLE): defined.
715 * read.c (scm_read_opts): add a keywords option. This isn't a
716 boolean option, in case someone wants to add support for DSSSL
718 Setup scm_keyword_prefix symbol.
719 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
721 I've left keyword support disabled by default, since it doesn't
722 seem to break the module system and it gives R4RS standard behaviour.
723 It can be reactivated with (read-set! keywords 'prefix).
725 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
727 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
728 before constructing arbiter.
730 * eval.c (scm_m_define): Bugfix: Check that the object is a
731 closure before setting the procedure property!
733 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
735 * ports.c: Removed `ungetc-char-ready?'.
737 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
739 * read.c (scm_init_read): intitialise scm_read_hash_procedures
740 (idea from Mikael: make it a pair so scm_permanent object only
742 (scm_read_hash_extend): don't call scm_permanent_object.
743 (ideas from Mikael): if chr is already in the list, replace its
744 procedure instead of appending it again. If proc is #f, remove
746 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
748 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
750 * gdbint.c (gdb_read): update scm_lreadr usage.
752 * load.h: update prototypes.
754 * load.c (scm_primitive_load, scm_read_and_eval_x,
755 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
757 * read.h: add prototype for scm_read_hash_extend. Change args for
760 * read.c (scm_read_hash_procedures): new variable.
761 (scm_read_hash_extend): new procedure.
762 (scm_get_hash_procedure): new procedure.
763 (scm_lreadr): use scm_get_hash_procedure instead of an argument
764 for extended # processing.
765 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
766 scm_read_token): remove case_i, sharp arguments. Change callers.
768 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
770 * read.h (SCM_N_READ_OPTIONS): increase to 3.
771 (SCM_CASE_INSENSITIVE_P): define.
773 * read.c: add case-insensitive option to scm_read_opts.
774 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
775 to determine whether to convert symbol case.
776 (default_case_i): definition removed.
777 * read.c (scm_read_token): if case_i, downcase ic before doing
780 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
782 * configure.in: Added configuration option `guile-debug'.
783 Configure with --enable-guile-debug if you want a bunch of extra
784 functions used for debugging when developing Guile.
786 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
788 * procs.c (make-cclo): New undocumented debugging procedure: Make
789 compiled closure with internal procedure PROC and length LENGTH.
790 Only compiled if GUILE_DEBUG is defined.
792 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
794 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
796 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
798 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
799 with 3 or more args internally to the evaluator.
801 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
803 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
804 with 3 or more args internally to the evaluator. This is mainly
805 because we don't want to pass entry and exit points of the
806 debug support twice, but it also seems to increase the speed of
807 the evaluator for such calls (e. g. (+ 1 2 3)).
809 * backtrace.c (scm_display_application): New procedure:
810 display-application; Set fancy printing parameters individually
811 for different types of display (backtrace, error, application).
812 (These should of course be customizable!)
814 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
815 clear the CHECK-flags.
817 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
819 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
821 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
823 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
824 from pairs with a GLOC in the car.
826 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
827 otherwise `symbol-hash' will behave badly.
828 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
829 we get segmentation fault!
831 * symbols.c: Added #include "weaks.h". New functions:
832 `builtin-bindings' and `builtin-weak-bindings'. (These will be
833 moved to an extraneous library when we split libguile.)
835 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
837 * filesys.c (scm_stat): stat now takes fport arguments too as
838 documented in the manual.
840 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
842 * debug.c (scm_single_step): Bugfix: Call continuation with
843 scm_call_continuation instead of throwing to it.
845 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
847 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
848 argument wasn't declared to be optional.
850 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
852 * stime.c (scm_init_stime): Add feature "current-time".
854 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
856 * throw.h: prototype for scm_exit_status.
857 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
858 args to derive an exit status. Allows (quit) to work from a
860 (scm_exit_status): new function.
863 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
865 * eval.c (scm_deval): Removed some old code.
866 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
868 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
871 * symbols.c (msymbolize): Bugfix: Must initialize property list to
874 * procs.c: Introduce the existent C function scm_thunk_p at the
875 Scheme level as well.
877 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
879 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
880 used from C to easily lookup the value of a symbol in the current
883 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
885 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
886 scm_init_unif in this file. This will also fix a previous problem
889 * configure.in: Added AM_MAINTAINER_MODE
891 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
893 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
896 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
898 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
899 source files that are not always included in libguile but should
900 have their dependencies calculated by automake. This variable is
901 recognized by automake, no further magic is needed.
902 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
903 to deal exclusively with *.lo files, as it seems. The *.o files
904 are built automatically when the corresponding *.lo file gets
907 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
909 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
912 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
914 * unif.c (scm_array_set_x): minor change to argument error checking.
916 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
918 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
919 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
920 They should only be included in the library at configure.in's
922 (libguile_la_LDADD): Include the appropriate .lo files here.
923 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
924 so we know when to build them (and their .lo bretheren).
925 * configure.in (LIBLOBJS): New substituted variable. We let
926 configure decide which .o files to include in LIBOBJS, and then
927 put the corresponding list of .lo files in LIBLOBJS. The latter
928 is what we pass to libtool.
929 * Makefile.in, configure: regenerated.
931 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
933 * symbols.c (scm_sysintern0): New function. Contains the core of
934 old scm_sysintern but doesn't take a second value argument.
935 (scm_sysintern): Now uses scm_sysintern0.
936 (scm_sysintern_no_module_lookup): Renamed to
937 scm_sysintern0_no_module_lookup and doesn't take a second value
940 * symbols.h (scm_sysintern0: Added declaration.
942 * options.c (scm_init_opts): Use scm_sysintern0 instead of
943 scm_sysintern when interning option keys. Otherwise we risk
944 destroying the values of already interned variables.
946 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
947 scheme-level boolean (use SCM_NFALSEP).
949 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
951 (scm_backtrace): New function. (C version of old function from
952 boot-9.scm) Motivation: Make it possible to display backtraces
953 without depending on boot-9.scm. (I'm uncertain if this
954 motivation is good enough...)
956 * root.h (scm_root_state): Add member the_last_stack_var.
957 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
959 * root.c (mark_root): Mark scm_the_last_stack_var.
961 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
964 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
966 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
967 1. mark_lazy_catch didn't mark the smob.
968 2. Both functions above have standard variants:
969 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
970 free_lazy_catch --> scm_free0.
972 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
974 * throw.c (scm_internal_lazy_catch): New function.
975 (scm_lazy_catch): Rewritten to use it.
976 (scm_ithrow): Handle the new lazy catch representation.
977 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
978 that doesn't have a jmpbuf is a lazy catch clause.
979 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
980 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
981 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
983 (scm_init_throw): Register the new lazy-catch smob type.
984 * throw.h (scm_internal_lazy_catch): decl for new function.
986 * throw.c (scm_internal_catch): Doc fixes.
988 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
989 configure.in. Including this might cause problems if applications
990 that link against libguile include their own copies of alloca, but
991 if they're using autoconf, they should be adding libguile to LIBS
992 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
993 the copy in libguile, and things will be okay. (I think.)
995 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
997 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
999 strop.h: move prototypes too.
1001 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
1003 * posix.c (scm_init_posix): don't intern EINTR since it's now done
1006 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
1007 etc. I deleted them from filesys.c long ago, but didn't
1008 notice they were here too (although ineffective since
1009 sys/stat.h wasn't included).
1011 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
1013 * eval.c: Don't define alloca in GCC case. gcc will automatically
1014 use __builtin_alloca if appropriate.
1016 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1018 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
1019 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
1020 that values of automatic variables are preserved. See comments
1021 for safe_setjmp for details.
1023 Change from Thomas Morgan:
1024 * variable.c: Include eq.h.
1025 (var_equal): New function.
1026 (variable_smob): Use var_equal as the discriminator for variables.
1028 * throw.c (s_throw): Remove extraneous declaration.
1030 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
1031 * eval.c: Add necessary CPP cruft to support that.
1032 * configure, Makefile.in, scmconfig.h.in: regenerated.
1034 Change from Thomas Morgan:
1035 * procprop.c (scm_procedure_properties): Convert the Scheme
1036 boolean returned by scm_procedure_p into a C boolean before using
1037 it as a condition for SCM_ASSERT.
1038 (scm_procedure_property): Likewise.
1040 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
1041 indications of Unixness.
1044 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1046 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
1048 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1050 * read.c (scm_lreadr): use scm_misc_error to improve one of the
1051 "unknown # object" error messages.
1053 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
1054 (scm_i_index) and declare it static. Add a 'direction' argument
1055 to indicate what way the search should go.
1056 (scm_i_index): throw out-of-range error instead of wrong-type-arg
1058 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
1059 strop.h: remove scm_i_index, scm_i_rindex prototypes.
1061 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1063 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
1065 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
1066 to avoid clash with various scsh forks.
1068 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
1070 The following two changes (ramap.c, throw.c) are motivated by the
1071 apparent unportability of forward declarations of static arrays of
1072 the form `static foo bar[];'.
1074 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
1075 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
1077 * throw.c (scm_throw): Moved above scm_ithrow.
1079 * options.h: Removed the extern declarations of scm_yes_sym and
1080 scm_no_sym since these are static.
1082 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1084 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
1086 * Makefile.am: remove AWK=@AWK@.
1087 Add a rule for generating errnos.list.
1088 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
1090 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
1091 don't extract errnos, just set a variable (avoids the
1092 need to recompile error.c just because configure is run.)
1094 * unif.h: update prototypes.
1095 * unif.c (scm_uniform_array_read,write): change the offset and
1096 length arguments to start and end, for consistency.
1098 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
1100 * ioext.h: update prototypes.
1101 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
1102 scm_read_line_x, it's a more general procedure using an
1103 interface from scsh. read-line and read-line! are now defined
1105 Note that the new read-line trims the terminator
1106 by default, previously it was appended to the returned string. An
1107 optional argument specifies how to process the terminator (scsh
1108 compatible). For the old behaviour: (read-line port 'concat).
1109 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
1110 returns a pair, but is converted to multiple values if the scsh
1113 socket.h: update prototypes.
1114 * socket.c (scm_recvfrom): for consistency with other procedures,
1115 take start and end as separate optional arguments.
1116 (scm_recv, scm_recvfrom): don't allow the second argument
1117 to be a size, only a buffer. Change the scheme names to
1118 recv! and recvfrom!. Don't return the buffer.
1120 * ioext.h, posix.h: move prototypes too.
1121 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
1122 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
1123 "read.h" and "unif.h".
1124 * ioext.c: include "chars.h"
1126 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
1128 * dynl.c: The dynamic linking and module registration functions
1129 are now defined even when dynamic linking is not available for the
1130 host system. Some of their functionality can be done without
1131 dynamic linking; when it's really needed, they throw errors.
1133 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
1135 * configure.in: Only define DYNAMIC_LINKING when one of the system
1136 dependent functions is detected.
1137 * dynl.c (scm_dynamic_func): New function to get the address of a
1138 function in a dynamic object.
1139 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
1140 produced by scm_dynamic_func as the thing to call.
1142 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
1144 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
1145 (scm_register_module_xxx, scm_registered_modules,
1146 scm_clear_registered_modules): New functions.
1148 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
1150 * symbols.c (scm_sysintern): Renamed to
1151 scm_sysintern_no_module_lookup.
1152 (scm_sysintern): New function to take the place of the old
1153 scm_sysintern. It uses the current toplevel lookup closure to give
1154 the symbol its value. This is a temporary hack to put packages
1155 like gtcltk into their own module.
1156 (scm_can_use_top_level_lookup_closure_var): New variable to tell
1157 us whether `scm_top_level_lookup_closure_var' has been initialized
1159 * eval.c (scm_init_eval): Set it.
1161 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1163 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
1164 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
1166 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
1168 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
1169 scm_sys_dup): deleted: FD capability will be added to other
1171 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
1172 scm_fd_free, fd_smob, scm_intern_fd.
1173 (scm_open): renamed from scm_sys_open. Return a port instead of
1174 an FD object. Make the mode argument optional.
1175 (scm_sys_create): deleted, it's just a special case of open.
1176 (scm_init_filesys): move interning of constants O_CREAT etc.,
1177 here (were previously using SCM_CONST_LONG macro).
1178 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
1180 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
1181 include "fports.h" and <stdio.h>
1182 (scm_stat, scm_select): don't support FD objects.
1184 * error.h: adjust scm_syserror_msg prototype.
1185 * error.c (scm_syserror_msg): take an extra argument for errno.
1186 Using the global value didn't always work, since it could be
1187 reset by procedure calls in the message or args arguments.
1189 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
1190 I don't understand why the check was there (and what about the
1193 * strop.c (scm_string_copy): allow shared substrings to be copied.
1195 * unif.h: corresponding change to prototypes.
1196 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
1197 recognize two new optional arguments: offset and length. Allow
1198 the port argument to be an integer (file descriptor, for scsh).
1199 Include <unistd.h> for "read" prototype.
1201 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1203 * socket.c: don't include filesys.h.
1205 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
1207 * Makefile.am: add AWK=@AWK@ (?)
1209 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
1211 Add a rule to generate errnos.c from errnos.
1212 * error.c (scm_init_error): include errnos.c.
1213 * errnos_cnvt.awk: new file, converts the list of errno codes to
1215 * errnos_get.c: new file.
1216 * errnos.default: new file, contains errnos to try if they can't
1217 be extracted from errno.h.
1218 * configure.in: if using GCC, try and extract errno codes from
1222 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
1224 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
1225 * Makefile.am: Made libguile into a libtool library.
1226 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
1227 Set libtool_libs to indicate that libguile is a libtool library.
1228 See guile/ChangeLog for details.
1229 * .cvsignore: ignore "*.lo", the libtool library objects.
1231 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1233 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
1234 use htons in getservbyport argument.
1236 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1238 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
1239 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
1242 * objprop.c (scm_object_property): No need to take the CDR of the
1243 value returned by scm_object_properties, since Aug 20 change.
1245 * configure.in: When checking for struct linger, #include
1246 <sys/types.h> as well as <sys/socket.h>. I've never known
1247 <sys/types.h> to cause any portability problems, and Solaris's
1248 <sys/socket.h> needs it.
1249 * configure: Rebuilt.
1251 I think the Sun compiler has chosen a perverse way to interpret
1252 ANSI declarations combined with K&R definitions. We'll
1253 appease it a little bit. But when it invades France, we fight.
1254 * print.c (scm_iprlist): Change 'tlr' argument to an int.
1255 * print.h (scm_iprlist): Here too.
1256 * numbers.c (scm_divbigdig): Change definition to match
1257 declaration in numbers.h.
1258 * unif.c (scm_makflo): Change definition to match declaration in
1261 * init.c (scm_boot_guile): Don't return the value of
1262 scm_boot_guile_1. This function doesn't return a value;
1263 scm_boot_guile_1 doesn't return a value (or return at all).
1265 * eval.c (unmemocopy): Add a semicolon to appease the Sun
1268 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
1269 compile. I have a feeling this function is a bad idea anyway ---
1270 one should always test for features, not systems.
1272 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
1273 semicolons. Only pure luck kept this from being noticed earlier.
1275 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
1277 * socket.c (scm_recvfrom): Added missing semicolon.
1279 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1281 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
1282 the buffer and start and end positions for scsh networking
1285 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
1287 * configure.in: Revert previous change to this file; the problem
1288 is due to transient automake weirdness.
1289 * configure: Rebuilt.
1291 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
1292 PLUGIN/guile.libs. configure generates the latter from the former.
1293 * Makefile.in: Rebuilt.
1295 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
1296 need this if we install scripts, like guile-snarf.
1297 * configure: Rebuilt.
1299 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1301 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
1303 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
1305 * socket.c (scm_addr_vector): fix faulty scm_listify.
1307 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
1309 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
1310 style block comment is no longer considered an error.
1312 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
1314 * PLUGIN/guile.libs.in: New file.
1315 * PLUGIN/guile.libs: Removed from repository.
1316 * configure.in: Create PLUGIN/guile.libs from
1317 PLUGIN/guile.libs.in. This is for including additonal libraries
1318 needed for dynamic linking.
1319 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
1320 instead of PLUGIN/guile.libs.
1322 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
1324 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
1326 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
1327 occurrences of the given element from the list, not just the
1328 first. This is how the Emacs Lisp functions behave, how the
1329 analogous Common Lisp functions behave, and (I believe) how the
1330 older Maclisp functions worked. I realize that this change may
1331 break code, but it seemed better to break it before the Guile
1334 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
1335 Their prototypes were already present in gc.h, but they weren't
1337 (scm_init_storage): Initialize scm_protects.
1338 * root.c (scm_protects): New element of scm_sys_protects.
1340 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
1342 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1344 * libguile.h: Added #include "libguile/net_db.h".
1346 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
1347 30 change. That file is only meant for communication between the
1348 configuration process and load.c. If code linked against libguile
1349 wants to get at the paths mentioned in libpath.h, it can call
1350 functions declared in load.h.
1352 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1354 * libguile.h: Removed #include "libguile/fdsocket.h"
1356 * net_db.c: Added #include <sys/socket.h>.
1358 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
1360 * filesys.c (scm_input_waiting_p): use select in preference to
1361 FIONREAD, since the latter doesn't detect EOF.
1362 Throw error if neither select nor FIONREAD available.
1364 * socket.c (scm_connect): take a port, not a fd object.
1365 (scm_fill_sockaddr): throw an error if fam is not recognised.
1366 (scm_bind): use scm_fill_sockaddr.
1367 (scm_listen): take a port, not a fd object.
1368 (scm_accept): take and return a port. return #f in the car if
1369 address can't be got
1370 (scm_sock_fd_to_port): new procedure.
1371 (scm_socket): use scm_sock_fd_to_port.
1372 (scm_addr_vector): throw error if unrecognised address type.
1373 take an extra argument with the calling procedure name.
1374 (scm_getsockname): take a port. return #f if address can't be got.
1375 (scm_getpeername): take a port. return #f if address can't be got.
1376 (scm_recvfrom): take a port. return #f for address component if can't
1378 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
1379 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
1381 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
1383 * throw.c (scm_internal_catch): Make body funcs and handler funcs
1384 use separate data pointers, to allow them to be designed
1385 independently and reused.
1386 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
1387 Renamed from catch_body, catch_handler, and uncaught_throw; made
1389 (struct scm_catch_body_data): Renamed from catch_body_data; moved
1391 (scm_catch): Use the above.
1392 (scm_throw): Don't bother printing a message for an uncaught
1393 throw; we establish a default handler in init.
1394 * throw.h (scm_internal_catch): Prototype updated.
1395 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
1397 (struct scm_body_thunk_data): New structure, used as data
1398 argument to scm_body_thunk.
1399 * init.c (struct main_func_closure): New structure, packaging up
1400 the data to pass to the user's main function.
1401 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
1402 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
1403 scm_internal_catch to establish a catch-all handler, using
1404 scm_handle_by_message. This replaces the special-case code in
1406 (invoke_main_func): Body function for scm_internal_catch; invoke
1407 the user's main function, using the main_func_closure pointer to
1408 decide what to pass it.
1409 * root.c (struct cwdr_body_data): Remove handler_proc member.
1410 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
1411 (cwdr_handler): Removed.
1413 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1415 * socket.h (SCM_P): update bind prototype.
1416 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
1417 include "feature.h".
1418 (scm_socket): return a port, not a file descriptor object.
1419 include "fports.h" and <unistd.h>
1420 (scm_bind): take a port, not a file descriptor object.
1421 take an extra argument for address args.
1423 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
1424 INADDR_NONE, INADDR_LOOPBACK.
1426 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1428 * init.c: include net_db.h and not fdsocket.h.
1429 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
1431 * Makefile.am: corresponding changes.
1432 * socket.h: renamed from fdsocket.h, fix names.
1433 * net_db.h: renamed from socket.h, fix names.
1434 * socket.c: renamed from fdsocket.c.
1435 remove _sys from procedure names.
1436 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
1437 add "socket" to features list.
1438 * net_db.c: renamed from socket.c.
1439 remove _sys from procedure names.
1440 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
1441 add "net-db" to features list.
1442 include "net_db.h". don't include <sys/socket.h> or
1445 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1447 * tags.h (scm_tags): Removed comma at end of last enumerator.
1449 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
1451 Don't use GCC extensions to allocate space for debugging frames.
1452 (Here he goes again! Why do we put up with this?!)
1453 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
1454 an scm_debug_info structure, not an in-line array of them. Add
1455 'info' member, to say how many vect elements we've used, for eval
1457 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
1458 a new variable debug_info_end to mark the end of vect, instead of
1459 the address of the 'info' pointer itself.
1460 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
1461 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
1462 (SCM_APPLY): Explicitly allocate space for debug.vect.
1463 * debug.c (scm_m_start_stack): Same, for vframe.vect.
1464 * stacks.c: Adjusted for new debug frame structure.
1465 (RELOC_INFO, RELOC_FRAME): New macros.
1466 (stack_depth, read_frames): Use them, and new scm_debug_frame
1467 element 'info', instead of magically knowing that eval frames have
1468 an info pointer sitting after vect.
1469 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
1471 (scm_init_stacks): Formatting tweaks.
1473 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
1475 Give GCC more control flow information, so it can be sure that
1476 variables aren't used uninitialized.
1477 * error.h (scm_error, scm_syserror, scm_syserror_msg,
1478 scm_sysmissing, scm_num_overflow, scm_out_of_range,
1479 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
1480 scm_misc_error): Tell GCC that these functions never return.
1481 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
1482 out the field type, call abort if SCM_ASSERT returns, to placate
1484 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
1485 scm_wta ever returns. We can't handle this case anyway, and this
1486 gives the optimizer more information.
1487 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
1488 scm_wta ever returns.
1490 In some cases, the code is fine, but GCC isn't smart enough to
1491 figure that out; this usually happens when one variable is only
1492 initialized and used when a particular condition holds true, and
1493 we know that condition will never change within a given invocation
1494 of the function. In this case, we simply initialize the variables
1495 to placate the compiler, hopefully to a value which will cause a
1496 crash if it is ever actually used.
1497 * print.c (scm_iprin1): Initialize mw_pos.
1498 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
1499 * throw.c (scm_ithrow): Initialize dynpair.
1500 * unif.c (scm_uniform_vector_ref): Initialize cra.
1501 * struct.c (init_struct): Initialize prot.
1502 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1504 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1505 if EXPR contains no expressions.
1507 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1509 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1510 cause an infinite loop (???). So much for the algebraic
1511 equivalency of variable-sized arrays and alloca...
1513 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1515 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1516 a SCM boolean, not a C boolean.
1518 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1520 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1521 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1522 rules for raising scm_mtrigger. Previously, unfortunate but not
1523 unlikely circumstances could result in almost constant invokation
1524 of the gc. Now, this situations should be less likely, but they
1525 are not prevented completely.
1527 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1529 * numbers.c (scm_fuck): Procedure removed; looks like old test
1531 * numbers.h: Prototype removed.
1533 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1535 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1536 array to a pointer, to match my Nov 21 change in eval.c.
1538 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1540 * libguile.h: Added #include "libguile/backtrace.h", #include
1541 "libguile/stacks.h".
1543 * strings.c (scm_string scm_make_string scm_string_ref
1544 scm_string_set_x scm_string_equal_p scm_string_append):
1545 Bugfix according to scm patch from Aubrey Jaffer:
1546 Corrected long-standing
1547 (not (eqv? (integer->char 128)
1548 (string-ref (make-string 1 (integer->char 128)) 0)))
1549 bug found by John Kozak <jk@noontide.demon.co.uk>.
1551 * strports.c, strports.h: Make scm_eval_0str return the value of
1552 the last expression evaluated (previously, it returned void).
1554 * strports.c, strports.h: New function: scm_read_0str. Does what
1557 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1559 * simpos.c (scm_getenv): return #f if string can't be found in the
1560 environment instead of throwing an exception, for compatibility
1561 with numerous other systems.
1563 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1565 * Makefile.am (.c.x): Use guile-snarf.
1566 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1568 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1570 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1572 * backtrace.c (scm_display_error_message): Made non-static, and
1573 renamed from display_error_message.
1574 * backtrace.h (scm_display_error_message): Added extern decl.
1575 * throw.c (uncaught_throw): Use it to display the error message.
1577 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1579 * inet_aton.c: Use #if 0, not #ifdef 0.
1581 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1583 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1584 to convert the returned value.
1585 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1586 the offset argument.
1588 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1590 Add new interface to catch/throw, usable from C as well as
1592 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1593 (scm_internal_catch): New function, replaces...
1594 (scm_catch_apply): Deleted.
1595 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1596 mechanism which is a bit more code, but can be used nicely from C
1597 and implement the Scheme semantics as well.
1598 (scm_internal_catch): This is the replacement; it's named after
1599 the analogous function in Emacs.
1600 (scm_catch): Reimplemented in terms of the above.
1601 (struct catch_body_data, catch_body, catch_handler): New
1602 functions, used by scm_catch.
1603 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1604 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1605 support for new cwdr.
1607 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1610 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1612 * acconfig.h: Added DYNAMIC_LINKING symbol.
1613 * configure.in: Add option and checks for dynamic linking.
1614 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1615 dynl.h: New files for dynamic linking support.
1616 * Makefile.am (libguile_a_SOURCES):
1618 (modinclude_HEADERS): Added "dynl.h".
1619 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1621 * init.c (scm_boot_guile_1): Call
1622 scm_init_dynamic_linking to initialize dynamic linking support.
1624 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1626 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1627 (as we Schemers say). It needs to be global, so that I can tweak
1628 it for the proper operation of unexec.
1629 (scm_boot_guile_1_live): New variable, see above.
1631 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1633 * guile-snarf.sh: Removed.
1634 * PLUGIN/guile.libs: Added dependency for -lm.
1635 * acinclude.m4: Renamed from aclocal.m4.
1636 * PLUGIN/greet: Removed.
1637 * Makefile.am, aclocal.m4: New files.
1638 * configure.in: Updated for Automake.
1640 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1642 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1643 and not top_level_lookup_thunk_var.
1645 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1647 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1649 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1651 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1652 Scheme function, instead of syntax. Single argument is now a
1655 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1657 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1658 scm_ra_divide): Properly terminate statements passed as arguments
1659 to IVDEP macros. (Thanks to Bernard Urban.)
1661 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1662 with non-constant sizes. (Thanks to Bernard Urban.)
1664 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1666 It's an "eval closure", not an "eval thunk." A thunk is a
1667 function of no arguments.
1668 * root.h (struct scm_root_state): Renamed
1669 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1670 (scm_top_level_lookup_closure_var): Renamed from
1671 scm_top_level_lookup_thunk_var.
1672 * root.c (mark_root): Uses changed.
1673 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1674 * init.c (scm_start_stack): Uses changed.
1675 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1676 Change scheme-visible name to *top-level-lookup-closure* from
1677 *top-level-lookup-thunk*.
1679 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1681 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1682 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1684 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1686 * gc.c (struct scm_heap_seg_data): Doc fixes.
1688 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1689 sweeping. Then, prepend each segment's free cells to its
1690 freelist, rather than wiping out the old value. (Thanks to Marius
1693 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1694 scm_check_freelist, scm_debug_newcell): New functions and
1695 variables, for debugging freelist problems.
1696 * pairs.h (SCM_NEWCELL): New debugging version added.
1697 * gc.h (scm_debug_newcell): Added extern declaration, used by
1698 debugging version of SCM_NEWCELL.
1700 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1702 On some systems <libc.h> conflicts with <unistd.h>, and should not
1703 be #included at all.
1704 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1705 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1706 * configure.in: Call it.
1707 * posix.c, filesys.c: Use its results to decide whether or not to
1709 * configure, scmconfig.h.in: Rebuilt with autoconf and
1712 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1714 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1715 pointer to the stdio stream before calling scm_setbuf0, so the
1716 latter will be able to retrieve it. I'm surprised this didn't
1717 segfault earlier. (Thanks to Christopher Lee.)
1719 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1721 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1724 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1726 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1727 number of stack narrowing specifier pairs. The first specifier in
1728 a pair controls inner border, the second the outer border. A
1729 number means cut that number of frames, a procedure object means
1730 cut until that object is found in operator position in a frame.
1732 * root.c (cwdr): Bugfix.
1734 * read.c: Recording of positions disabled by default.
1736 * procs.c (scm_closure_p): New function.
1738 * posix.c (scm_tmpnam): New function.
1740 * load.c: Added #include "throw.h".
1741 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1744 * load.c, load.h (scm_read_and_eval_x): New function.
1746 * eval.c: Renamed debug option "deval" to "debug".
1748 (scm_eval_x): `eval!' is no longer accessible from the scheme
1749 level. Motivation: We can't allow operations which introduce
1750 glocs into the scheme level. Guile's type system can't handle
1751 these as data. Use `eval' or `read-and-eval!' as replacement.
1753 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1754 SCM_CONSP since this is a macro!; Set vframe.prev to
1755 scm_last_debug_frame instead of 0. In this way we can look
1756 "above" the virtual start stack frame if we wish.
1757 (scm_debug_hang): New function: Useful for debugging Guile in
1758 certain tricky situations. Will probably be removed later...
1760 * debug.h: Changed semantics of debug option "backtrace". This
1761 option now only indicates whether we want automatic backtrace at
1764 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1766 * ports.c: #include "filesys.h"
1767 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1769 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1770 Motivation: This is system specific code which is related to file
1771 I/O. It also may use select. Added code by Gary Houston to
1772 detect presence of character in stdio buffers.
1774 * libguile.h: #include "libguile/libpath.h"
1776 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1777 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1778 SCM_SITE_DIR; Install libpath.h among the other include files.
1780 * load.c, load.h (scm_sys_package_data_dir): New function.
1782 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1784 * stacks.h: Bugfix: Don't use tail-array length field as stack
1785 length field! This screwed GC.
1787 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1789 * _scm.h: Added #ifndef around definition of macros min and max.
1791 * __scm.h: Added hooks for threads to plugin to in ints protection
1792 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1793 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1794 the main code in these macros duplicated and spread over multiple
1795 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1796 SCM_THREAD_SWITCHING_CODE.
1798 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1800 * snarf.h: New file.
1801 * guile-snarf.sh: New file.
1802 * Makefile.in (inner_h_files): Added snarf.h
1803 (ancillary, install, uninstall, distclean): Added actions for
1805 (.c.x): Use guile-snarf.
1806 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1807 (gen_c_files): Note that these depend on guile-snarf.
1808 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1809 now in "snarf.h". Added #include "snarf.h" to get them.
1810 * libguile.h: Added #include "snarf.h".
1811 (Patches applied and tweaked by Jim Blandy.)
1813 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1815 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1816 standards suggest against providing prototypes for system
1817 functions. Thanks to Greg Troxel.
1819 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1821 * strports.c (scm_eval_0str): New function.
1822 #include "read.h", to get prototype for scm_read.
1823 * Makefile.in (strports.o): Update dependencies.
1824 * strports.h: New prototype.
1826 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1827 scheme name from "int?" to "integer?". It seems to do the job.
1828 * numbers.h: Rename prototype too.
1829 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1832 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1833 scm_num_eq_p): Rename these according to R4RS conventions: call
1834 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1835 to making libguile R4RS compliant without ice-9...
1837 * load.c (scm_sys_search_load_path): Search for files under all
1838 extensions listed in the %load-extensions variable. If FILENAME
1839 is absolute, return it unchanged, without searching the load path.
1840 (scm_loc_load_extensions): New variable, pointing to
1841 %load-extensions' value cell.
1842 (scm_init_load): Initialize it, and the value it points to.
1843 (scm_primitive_load_path): Improve error reporting.
1845 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1846 of new Scheme variable %load-hook.
1847 (scm_primitive_load): Apply %load-hook to filename.
1849 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1851 * configure.in: add tests for figuring out whether buffered data
1852 is available in a FILE structure, which is needed by char-ready.
1854 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1857 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1858 exceptions using misc_error instead of syserror. It seems a bit
1859 odd to throw an exception if a string can't be found in the
1860 environment, but it's consistent with open-file, stat etc.
1861 (simpos.h): remove sys_ from getenv.
1863 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1864 occurs, throw an error instead of returning errno. Return value
1866 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1868 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1870 * filesys.c (scm_stat2scm): derive file type and permissions from
1871 the stat mode and append them to the returned vector.
1872 There isn't much overhead in doing this and it avoids the need to
1873 work with S_IRUSR et al. in Scheme.
1874 Define symbols scm_sym_regular etc.
1875 (scm_init_filesys): don't intern S_IRUSR etc.
1877 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1878 and s_primitive_load_path.
1880 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1882 * error.h: don't declare error symbols. prototype for scm_misc_error.
1884 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1887 * error.c: use SCM_SYMBOL to set up error keys.
1888 scm_misc_error: new procedure.
1890 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1892 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1893 between `#!' and `!#' is ignored.
1894 (skip_scsh_block_comment): New function.
1896 * feature.c (scm_set_program_arguments): New argument, FIRST.
1897 * feature.h: Update prototype.
1898 * init.c (scm_boot_guile_1): Pass new argument to
1899 scm_set_program_arguments.
1901 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1903 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1904 (scm_boot_guile): Call scm_set_program_arguments here, later than
1905 the old initialization.
1907 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1908 initialization procedure.
1909 - Delete in, out, err arguments; there are other perfectly good
1910 ways to override these when desired.
1911 - Delete result argument; this function shouldn't ever return.
1912 - Rename init_func argument to main_func, for less confusion.
1913 - Delete boot_cmd argument; main_func is more general.
1914 -Add 'closure' argument, to help people pass data to main_func
1915 without resorting to global variables.
1916 - Abort if reentered; don't bother returning an error code.
1917 - Call scm_init_standard_ports to set up the default/current
1918 standard ports; no need to pass them to scm_start_stack.
1919 - Remove code to evaluate the boot_cmd, and start the repl; let
1920 the user do something like that in main_func if they want.
1921 - Remove code to package up a return value; main_func can do any
1923 - Call exit (0), instead of returning.
1924 (scm_start_stack): Don't initialize the I/O ports here; that's
1925 weird. Delete in, out, err arguments. Move guts to
1926 scm_init_standard_ports, scm_stdio_to_port.
1927 (scm_init_standard_ports): New function, to set up current and
1928 default standard ports.
1929 (scm_start_stack, scm_restart_stack): Make these static.
1930 * init.h (scm_boot_guile): Adjust declaration.
1931 (scm_start_stack, scm_restart_stack): Remove externally
1932 visible declarations for these.
1933 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1935 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1936 written out several times in scm_start_stack.
1937 * fports.h: New declaration for the above.
1939 * feature.c (scm_set_program_arguments): New function.
1940 * feature.h: New declaration for the above.
1942 * ports.c: Formatting tweak.
1944 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1946 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1947 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1948 for obtaining the address of a car or cdr field. Motivation:
1949 &SCM_CXR make assumptions about the internal structure of the
1952 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1953 Motivation: see SCM_CXRLOC.
1955 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1956 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1957 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1958 Motivation: Safer use. Some other macros are defined in terms of
1959 these operations. If these are defined using the SCM_SETCXR
1960 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1961 to inefficiency and an <e1> with side-effects could potentially
1962 break. Also, these particular operations are heavily utilized in
1963 the garbage collector. In unoptimized code there will be a
1966 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1967 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1968 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,

1971 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1972 vports.c: Cleaned up use of pairs: Don't make any special
1973 assumptions about the internal structure of selectors and
1974 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1975 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1976 (Among other things, this change makes it easier to build Guile
1977 with certain compilers which have problems with casted lvalues.)
1979 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1981 * stacks.c: Improve selection of relevant stack frames when making
1982 a stack object. Introduce one level of indirection in the stack
1983 object to make it possible to "narrow" to a certain region of the
1984 stack. This facilitates making use of more clever algorithms (not
1985 implemented) for selecting relevant frames and gives a cleaner
1986 design since selection of frames can be done independently of
1987 extraction of frames from the real stack.
1988 (scm_stack_id): Also take #t as argument which means look at
1991 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1992 Turn n_tail into an integer directly representing current number
1993 of frames in stack. Add field tail.
1995 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1997 * debug.c (scm_make_memoized): Made it available at scheme level.
1998 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1999 SCM_NIMP before applying heavier predicates in argument checking.
2000 (scm_local_eval): Also take memoized object as argument.
2002 * backtrace.c (scm_display_error): Just a safety measure: Stacks
2003 aren't created with zero length, but should such a strange
2004 creature suddenly turn up...
2006 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
2008 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
2009 `del', for the sake of C++ compilers. (Patch applied by JimB.)
2011 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
2013 * variable.c (scm_make_variable): Make the name hint optional, as
2015 (anonymous_variable_sym): Renamed from variable_sym. All uses
2018 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
2019 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
2020 of scm_primitive_load_path was also changed to
2021 "primitive-load-path", from "%try-load-path". Callers changed.
2022 We'd like to respect the convention that a function named
2023 "try-mumble" should behave just like the function called "mumble",
2024 but return #f instead of signalling some error.
2025 * load.h: Rename prototypes.
2027 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2029 * print.c (make_print_state, grow_print_state), print.h: Modified
2030 the print state representation: Don't use a tail array for
2031 recording of circular references. Resizing of the print state
2032 structure invalidates the print state pointer. To avoid passing
2033 around an indirect print state reference to all printing
2034 functions, we instead let the print state reference a resizable
2037 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2039 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
2040 Don't crash when passed an improper list terminated by a
2041 non-immediate value.
2043 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
2045 Allocate data for structures on an eight-byte boundary, as
2046 required by the tagging system.
2047 * struct.c (alloc_struct): New function.
2048 (scm_make_struct, scm_make_vtable_vtable): Call it.
2049 * struct.h (scm_struct_n_extra_words): Bump to 3.
2050 (scm_struct_i_ptr): New "field".
2051 * gc.c (scm_gc_sweep): When we need to free the data, use the
2052 information stored by alloc_struct to find the beginning of the
2053 block allocated to the structure, so we can free it.
2055 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2057 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
2060 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
2061 (scm_debug_info): New member: id.
2063 * stacks.c: Stacks are now represented as structs; Stacks have an
2064 id given to them by `start-stack'.
2065 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
2067 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
2068 Changed stack representation.
2070 * debug.c (scm_procedure_name): Try procedure property `name' for
2071 compiled closures aswell.
2073 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
2075 * eval.c: scm_i_name moved to gsubr.c
2076 (scm_m_define): Record names of all kinds of procedure
2077 objects. (Earlier, only closures were recorded.)
2079 * procprop.h: Added declaration of scm_i_name.
2081 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
2082 (scm_make_gsubr): Record names of compiled closures.
2084 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2086 * debug.c, debug.h: Removed obsolete code.
2088 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
2089 stacks.c: Renamed regs --> scm_contregs.
2091 * print.c (scm_free_print_state): Cleanup print state before
2092 returning it to pool. It is better to do it here than in
2093 scm_prin1 since scm_prin1 is called often.
2095 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
2096 s_set_source_property_x): Check that first argument is a pair or a
2099 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
2100 scm_i_line, scm_i_column and scm_i_breakpoint global.
2102 * init.c: Added #include "backtrace.h" and #include "stacks.h".
2103 (scm_boot_guile_1): Added calls to scm_init_backtrace and
2106 * debug.h: Added debug object smob declaration and macro
2109 * configure.in: Build with backtrace.o and stacks.o if debug
2112 * Makefile.in: Added entries for new files: backtrace.c,
2113 backtrace.h, stacks.c and stacks.h.
2115 * symbols.c (scm_sym2ovcell): Fixed documentation.
2117 * _scm.h (min, max): Added.
2119 * async.c: Moved `min' macro to _scm.h.
2121 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
2122 SCM_BACKTRACE_INDENT.
2124 * eval.c: Added new debug options `maxdepth' and `indent'.
2126 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
2128 * print.h: Added selector SCM_PRINT_STATE.
2130 * print.c: New functions: scm_make_print_state,
2131 scm_free_print_state.
2133 * print.h: Added declarations for scm_make_print_state,
2134 scm_free_print_state.
2136 * debug.c (scm_m_start_stack): New acro.
2138 * debug.h: Small cleanup.
2140 * init.c (scm_boot_guile_1): Moved scm_init_debug below

2165 declare functions with prototypes. (Patch thanks to Marius
2168 More prototype-related changes from Marius Vollmer:
2169 * gdb_interface.h: Wrapped header file in #ifdef/#endif
2170 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
2171 * ports.h (ptobfuns): Added prototypes. This means some casting in
2173 * fports.c: Added casts for initializations, since the functions
2174 are defined to take FILE * as their stream argument, not SCM.
2175 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
2176 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
2177 to `char *str_data' to conform to prototype.
2179 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2181 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
2183 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
2185 * stime.c, stime.h: use SCM_P method.
2187 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2189 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
2190 be given at least two arguments. Insist that lst's last element
2191 be a list, but don't make any requirements of its predecessors.
2193 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2195 * eval.c (scm_nconc2last): Revert last change; there seems to be
2196 other stuff going on here.
2198 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2200 * eval.c (scm_nconc2last): Make sure that each element of lst
2201 (which is a list of argument lists, except for the tail) is a
2202 proper list, i.e., finite and terminated by '().
2204 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2206 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
2209 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
2210 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
2213 * vectors.c (scm_make_vector): Fill vectors with the undefined
2214 value, to help make Guile Scheme code more portable to other
2217 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
2218 * symbols.h, tags.h: Doc fixes.
2220 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
2222 * async.c (scm_take_signal): Doc fixes.
2224 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
2226 * numbers.c (scm_divbigint): When the remainder is zero, we don't
2227 want to subtract it from the modulus; we just want to leave it
2230 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
2232 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
2235 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
2237 * throw.c (scm_catch_apply): Finished implementation of
2240 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2242 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
2244 (scm_init_filesys): set "i/o-extensions" feature.
2247 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
2249 * Makefile.in (root.o): Correct dependencies.
2251 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
2253 * Makefile.in: Added dependency entry for root.o.
2255 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
2256 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
2258 * init.c (scm_start_stack): Set initial root continuation number
2261 * procs.c: New function: scm_thunk_p.
2263 * procs.h: Added declarations of scm_thunk_p.
2265 * root.c: Renamed `call-with-new-root' -->
2266 `call-with-dynamic-root'.
2267 (cwdr): Removed allocation of new root state. This should be done
2268 separately by use of scm_make_root.
2269 (scm_apply_with_dynamic_root): New function: Does what it
2270 sounds like. Needed when spawning threads.
2272 * root.h: Added member last_debug_frame to root state.
2273 Added #include "libguile/debug.h"
2275 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
2276 arguments. The motivation is that code in root.c needs catch
2277 functionality, and we want to avoid code duplication.
2278 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2279 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2280 handlers that run without popping the stack into the dynwind
2283 * throw.h: Added prototypes for scm_catch_apply and
2286 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2288 * root.h (scm_root, scm_set_root): Decouple thread support details
2289 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2290 SCM_SET_THREAD_LOCAL_DATA.
2292 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2293 and tortoise scanning loop.
2295 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2297 * Makefile.in: Rebuild dependencies.
2299 * libguile.h: #include "libguile/print.h" before "smob.h", since
2300 the latter uses the print_state structure.
2302 * throw.c (scm_ithrow): Use the correct variable when checking to
2303 see if a given element of scm_dynwinds is a valid catch.
2305 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2306 structure, abort; don't just silently ignore the garbage.
2308 * _scm.h: #include "print.h" here, since it seems to be used just
2310 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2311 strports.c, unif.h: Don't #include "print.h".
2313 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2315 * feature.h (scm_loc_features): Removed external declaration.
2316 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2318 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2320 * feature.c (scm_init_feature): Added threads feature (needs to be
2321 initialized here, since features doesn't exist when
2322 scm_init_threads is called).
2324 * libguile.h: Added #include "libguile/../threads/threads.h".
2325 (This is a kludge to get thread support working. This should be
2328 * configure.in, acconfig.h: Added flags for thread support.
2330 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2333 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2334 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2337 * _scm.h: Added conditional #include "threads.h"
2339 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2340 SCM_THREADS_SWITCHING_CODE.
2342 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2343 allocate the basic dynamic root object.
2344 (scm_boot_guile): Added call to scm_init_root.
2346 * root.c, root.h: Added root smob.
2347 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2348 functions: Implements dynamic roots mostly according to spec in
2349 SCM manual. Main difference is that the second argument is a
2350 throw handler rather than an error "thunk".
2352 * root.h: Added declaration of scm_init_root.
2354 * root.c: Added #include "genio.h", #include "smob.h", #include
2355 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2357 (scm_init_root): Added #include "root.x".
2359 * throw.c: Added #include "stackchk.h"
2360 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2361 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2362 can be used in scm_call_with_new_root; Added reenabling of stack
2363 checking when catching a throw.
2365 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2367 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2369 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2370 element is not found, as per R4RS.
2372 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2374 * list.c: Doc fixes throughout.
2376 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2378 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2379 declare the char * to be const. Avoids a warning in rgx.c.
2381 * ports.h: spelling fix.
2383 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2386 * load.c (scm_sys_try_load_path): throw an error if file not found
2387 (like it says it in NEWS).
2389 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2391 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2392 PROPS slot to '(), not #f; it's an empty alist.
2394 * throw.h, throw.c: Use SCM_P instead of #if hair.
2396 Remove special support for uncaught throws; see throw.c for
2398 * throw.c (uncaught_throw): New function.
2399 (scm_ithrow): Call uncaught_throw if we don't find a throw
2400 target; don't mess with scm_bad_throw_vcell.
2401 (scm_bad_throw_vcell): Variable deleted.
2402 (scm_init_throw): Don't initialize it.
2404 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2407 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2409 * numbers.c (scm_istr2int): If the number is short (as most
2410 numbers are), just call scm_small_istr2int to deal with it.
2411 (scm_small_istr2int): New function, created by un-#ifdefing the
2412 non-bignum version of scm_istr2int and renaming it.
2414 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2416 * load.c (scm_sys_try_load): don't check whether value returned
2417 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2418 Change the Scheme name from %try-load to primitive-load.
2420 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2421 Can avoid passing a message, allowing it to be derived in the
2422 error handler (e.g., if we want to throw to the key both from
2425 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2427 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2428 references now have a new appearance which is more compact and
2429 also gives a clue about what the target of the reference is.
2430 By setting parameters in the print state, more fancy printing can
2431 be achieved. This is used by the (not yet commited) backtrace
2434 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2436 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2439 * print.c: Added #include "struct.h". Removed function
2442 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2443 scm_iprin1. Removed prototype for scm_prlist.
2445 * arbiters.c (prinarb),
2446 async.c (print_async),
2447 debug.c (prindebugobj, prinmemoized),
2448 eval.c (prinprom, prinmacro),
2449 filesys.c (scm_fd_print, scm_dir_print),
2451 mallocs.c (prinmalloc),
2452 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2453 smob.h (scm_smobfuns),
2454 srcprop.c (prinsrcprops),
2456 unif.c, unif.h (scm_raprin1, rapr1),
2457 variable.c (prin_var): Changed argument `int writing' to
2458 `scm_print_state *pstate'.
2460 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2461 that it will be called before scm_init_print.
2463 * print.c (scm_prin1): Print states are now allocated when calling
2464 scm_prin1 and then passed around to all printing functions as an
2465 argument. A cache `print_state_pool' enables reuse of print
2467 (scm_make_print_state): New function.
2468 (scm_iprin1): Adaption to print states.
2469 (scm_iprlist): An initial "hare and tortoise" scan brings down
2470 time complexity to O (depth * N). (Better time complexity will be
2471 achieved when the printing code is completely rewritten.)
2473 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2475 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
2476 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
2477 it gets done whether or not the cache variable has a value.
2479 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2481 Distinguish #f and ().
2482 * __scm.h: #undef SICP.
2483 * pairs.h (SCM_EOL): Delete this definition, equating it with
2485 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2486 the value it used to have. Doc fixes, too.
2488 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2490 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2491 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2492 Lord's implementation of structs, allowing for tail arrays as
2493 described in the manual. Also fixed some bugs. (Both the interface
2494 and the implementation should be improved.)
2496 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2498 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2499 People who whish to see the source can do `(print-enable 'source)'.
2500 Removed #ifdef DEBUG_EXTENSIONS.
2502 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2504 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2505 integer (assuming for now accepting an integer is a good thing).
2507 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2508 %S will be used instead for write'ing arguments.
2510 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2511 asserts. fix a few other asserts.
2512 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2513 scm_uniform_vector_ref, scm_array_set_x,
2514 scm_dimensions_to_unform_array): change args in
2515 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2516 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2517 scm_substring_fill_x): likewise.
2518 gsubr.c (scm_gsubr_apply): likewise.
2519 eval.c (SCM_APPLY): likewise.
2521 * eval.c (4 places): replace scm_everr with lgh_error or
2524 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2525 scm_memory_error): new procedures.
2526 scm_everr: deleted. can use scm_wta, dropping first two args.
2527 scm_error: convert NULL subr to SCM_BOOL_F.
2529 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2532 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2535 * error.c, error.h: new error keys: scm_arg_type_key,
2536 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2538 scm_wta: reimplement using lgh_error instead of scm_everr.
2540 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2542 * gdbint.c: scm_lread now has one more argument.
2544 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2545 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2546 loading source from non-file ports, which, e. g., happens when
2547 using the Emacs interface).
2549 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2552 * read.c: Added code for recording of positions of source code
2553 expressions; New functions: recsexpr, scm_lreadrecparen;
2554 _scm_make_srcprops --> scm_make_srcprops
2555 (scm_flush_ws): Removed updating of positions counters. This work
2556 is already done by scm_gen_getc
2558 * read.h: Added prototype for scm_lreadrecparen
2560 * print.c: Added #include "alist.h"
2562 * eval.c: Added #include "hash.h"
2564 * eq.c: Added #include "ramap.h"
2566 * options.c: Documentation fixes.
2568 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
2569 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2570 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2571 --> scm_make_srcprops
2573 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2574 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2575 function calls in the definition of the whash access macros.
2577 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2579 * init.c (scm_boot_guile): Add level of indirection to
2580 scm_boot_guile_1() to ensure that stack base pointer is properly
2581 initialized. There was no guarantee that variable i was the
2582 highest/lowest variable on stack (i.e. the call frame of
2583 scm_boot_guile was not completely protected from gc).
2585 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2587 * ports.h (scm_port_table): put back file_name, it will be used to
2588 support debugging. Undo related changes in fports.c, ioext.c,
2591 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2593 * ports.h (scm_port_table): remove file_name member for now, it seems
2595 * fports.c (scm_open_file): don't set file_name in PTAB.
2596 (prinfport): don't use file_name in PTAB.
2597 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2598 * ports.c (scm_add_to_port_table): don't intialize file_name.
2599 (scm_port_file_name): remove for now.
2600 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2602 * fports.h (scm_mkfile): prototype deleted.
2603 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2605 * debug.c, unif.c: use scm_out_of_range instead of
2606 wta for range errors (ASSERT still needs work).
2608 * error.c, error.h (scm_out_of_range): new procedure.
2610 * error.c, error.h (scm_out_of_range_key): new key.
2612 * posix.c (scm_sync): #else was missing.
2614 * error.c, error.h: append _key to names scm_num_overflow and
2617 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2618 of consing an empty list.
2619 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2620 of macros, saves code and string space.
2621 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2622 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2623 lower case. Rename scm_syserror_m to scm_syserror_msg.
2624 error.h: prototypes for new procedures.
2626 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2628 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2630 * error.c, error.h: setup scm_num_overflow key.
2632 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2633 Remove definition of SCM_OVSCM_FLOW.
2635 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2637 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2638 explicit message and args.
2640 * error.c, error.h, __scm.h: change system_error_sym to
2643 * error.c (system_error_sym): remove leading %% from the Scheme name
2646 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2648 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2650 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2651 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2652 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2653 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2654 renamed. (These were introduced by unsupervised name
2657 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2659 * print.c: Added code for detection of circular references during
2660 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2661 a hook for printing of closures (accessible via print options).
2662 This leads to a split of calls to scm_iprin1 into two classes:
2663 elementary print operations (e. g. the code which prints a smob)
2664 still use scm_iprin1 while top level calls (like scm_display) use
2665 scm_prin1. scm_prin1 begins by clearing the data structure used
2666 to record reference information.
2668 * print.h: Added declarations of scm_prin1 and scm_prlist.
2670 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2672 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2674 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2676 * error.c (err_head): scm_iprin1 --> scm_prin1
2678 * debug.c: Adjusted header comment.
2682 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2684 * strerror.c: Doc fix.
2686 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2688 * gdbint.c (gdb_read): Now possible to run during GC.
2689 (unmark_port, remark_port): New functions.
2691 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2693 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2694 of allocating a new string object. Also, increase size by
2695 the factor 2 instead of 1.5.
2697 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2699 * __scm.h (SCM_P): Corrected to run under traditional C.
2701 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2704 * async.c: Calls to scm_sysintern corrected.
2706 * async.h (scm_async_clock): Redundant declaration removed.
2708 * continuations.c (scm_dynthrow): Redundant declaration removed.
2710 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2711 Definition typos corrected.
2713 * debug.h: Missing declarations of functions in debug.c added
2716 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2717 Missing declarations to functions in eval.c added.
2719 * filesys.c: Possibly uninitialized variable rv.
2721 * gc.h (scm_object_addr, scm_unhash_name): Missing
2722 declarations of functions defined in gc.c added.
2724 * genio.c: Possible typos str_data -> wstr_data. ???
2726 * genio.c: Possibly unintended shadowing of local variable
2727 `int c' (gotos out of scope of inner `c'). ???
2729 * init.c: Uninitialized `SCM last' may be used.
2731 * ioext.h: (scm_sys_isatty_p): Typo.
2733 * list.h (scm_list_head): Missing prototype for function in
2736 * numbers.c (scm_two_doubles): Changed from extern to static
2737 (is used only within numbers.c).
2739 * numbers.h: Repeated declarations removed.
2741 * ports.h (scm_close_all_ports_except): Declaration for the
2742 function defined in ports.c added.
2744 * posix.h: Missing declarations added.
2746 * procs.h (scm_make_subr_opt): Missing declaration added.
2748 * socket.h (scm_sys_gethost): Missing declaration added.
2750 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2752 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2753 Missing declarations added.
2755 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2757 * struct.c: Uninitialized variable `SCM answer' may be used.
2759 * unif.c (l2ra): Declaration prototype.
2761 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2762 defined in ramap.c).
2764 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2765 Redundant declarations removed (they are in ramap.h).
2767 * variable.h (scm_make_udvariable,
2768 scm_make_undefined_variable): Declaration corrected to
2769 correspond variable.c.
2771 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2772 Missing declarations added.
2774 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2776 * Makefile.in (distclean): Don't forget to delete fd.h.
2778 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2780 * fd.h.in, tags.h: Trivial cleanups.
2782 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2783 marksweep.h just declared functions from gc.c.
2784 * gc.h, libguile.h: Don't #include "marksweep.h".
2785 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2786 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2787 dependencies updated.
2789 * libguile.h: Don't #include "files.h"; it's been deleted.
2791 * files.c (scm_sys_delete_file): Moved to filesys.c.
2792 File is now empty; deleted.
2794 * filesys.c: scm_sys_delete_file is now here. Remove
2795 #if's; they seem to rely on remnants of an old portability
2796 regimen. If the problems come up again, solve them properly,
2797 using autoconf. Specifically: Don't test M_SYSV, and #define
2798 remove to be unlink if it's #defined; don't use remove just
2799 because HAVE_STDC_HEADERS is #defined.
2800 * filesys.h: Add declarations for scm_sys_delete_file.
2801 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2802 files.o, files.h, files.c, and files.x.
2803 * init.c: Don't #include "files.h", and don't call scm_init_files.
2805 Use SCM_P instead of PROTO; the latter intrudes on the user's
2807 * params.h: Deleted; definition of SCM_P moved to...
2808 * __scm.h: ... here, where it replaces PROTO macro.
2809 * libguile.h, smob.h: Don't #include "params.h".
2810 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2811 smob.h: Fix prototypes accordingly.
2812 * Makefile.in: Update dependencies.
2813 (inner_h_files): Remove params.h.
2815 * gc.c: #include "gc.h"; every module should include its header,
2816 to let the compiler cross-check the declarations against the
2819 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2820 simpos.h: #include "libguile/__scm.h".
2822 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2824 * init.c: Don't forget to #include smob.h and init.h.
2825 * Makefile.in: Dependencies updated.
2827 * smob.h: Use PROTO instead of #if __STDC__.
2829 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2831 * __scm.h: Doc fixes.
2833 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2834 <angles>; this allows `make depends' to work properly.
2836 * libguile.h: #include smob.h and pairs.h before the others; they
2837 define typedefs used by other headers.
2839 C files should #include only the header files they need, not
2840 libguile.h (which #includes all the header files); the pointless
2841 recompilation was wasting my time.
2842 * Makefile.in (all .o dependency lists): Regenerated.
2843 * libguile.h: Don't try to get a definition for size_t here...
2844 * __scm.h: Do it here.
2845 * _scm.h: Since this is the internal libguile header, put things
2846 here that all (or a majority) of the libguile files will want.
2847 Don't #include <libguile.h> here; that generates dependencies on
2848 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2849 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2850 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and
2852 * alist.c: Get "eq.h", "list.h", "alist.h".
2853 * append.c: Get "append.h", "list.h".
2854 * arbiters.c: Get "arbiters.h", "smob.h".

2861 "continuations.h", "alist.h", "srcprop.h", "procprop.h", "smob.h",
2862 "genio.h", "throw.h", "eval.h".
2863 * dynwind.c: Get "dynwind.h", "alist.h", "eval.h".
2864 * eq.c: Get "eq.h", "unif.h", "smob.h", "strorder.h",
2866 * error.c: Get "error.h", "throw.h", "genio.h", "pairs.h".
2867 * eval.c: Get "eval.h", "stackchk.h", "srcprop.h", "debug.h",
2868 "hashtab.h", "procprop.h", "markers.h", "smob.h", "throw.h",
2869 "continuations.h", "eq.h", "sequences.h", "alist.h", "append.h",
2871 * fdsocket.c: Get "fdsocket.h", "unif.h", "filesys.h".
2872 * feature.c: Get "feature.h".
2873 * files.c: Get "files.h".
2874 * filesys.c: Get "filesys.h", "smob.h", "genio.h".
2875 * fports.c: Get "fports.h", "markers.h".
2876 * gc.c: Get "async.h", "unif.h", "smob.h", "weaks.h",
2877 "genio.h", "struct.h", "stackchk.h", "stime.h".
2878 * gdbint.c: Get "gdbint.h", "chars.h", "eval.h", "print.h",
2879 "read.h", "strports.h", "tag.h".

2883 * hashtab.c: Get "hashtab.h", "eval.h", "hash.h", "alist.h".
2884 * init.c: Get everyone who has an scm_init_mumble function:
2885 "weaks.h", "vports.h", "version.h", "vectors.h", "variable.h",

2949 * stackchk.h: #include "libguile/debug.h",
2951 * print.h, read.h: #include "options.h", since everyone who uses
2952 either of these files will need that.
2954 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2955 anyone who uses this file will need them to define the smob
2956 printing functions. Also, get markers.h, since people will need
2957 to #define the mark functions.
2959 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2960 * ports.h: ... to here.
2962 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2963 don't rely on archaic C default type rules.
2965 * fports.h: #include "libguile/ports.h", since you need that in
2966 order to parse this.
2968 * genio.h: #include "libguile/print.h", because you need that to
2969 parse this; don't bother #including "ports.h", since print.h gets
2972 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2974 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2975 this; it's now a reference to an element of *scm_root.
2977 * debug.h: Don't #include "options.h"; the compiler won't be able
2978 to find that once the headers are installed; instead, #include
2979 "libguile/options.h".
2980 * gc.h: Same, with marksweep.h.

2982 * scmhob.h: Same, with _scm.h.
2983 * smob.h: Same, with params.h.
2985 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2986 C files; there's no need for this, and it forces recompilations
2989 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2991 * error.c (scm_error): declare scm_error_callback.
2993 * error.h: prototype for scm_error_callback.
2995 * __scm.h: define lgh_error.
2996 (SCM_SYSERROR): redefine using lgh_error.
2998 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
3000 * error.c (scm_error): new procedure.
3002 * error.h: prototype for scm_error.
3004 * Makefile.in (install): install scmconfig.h from the current
3005 directory, not $(srcdir).
3007 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
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, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

3017 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3018 vports.h, weaks.h: #include "libguile/__scm.h", not
3019 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
3020 dependencies are within libguile properly.
3022 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3024 * Makefile.in (.c.x): Simplify; there's no need to run this rule
3025 when scmconfig.h doesn't exist.
3027 * load.c (scm_sys_try_load): Correct spelling.
3029 * feature.c (scm_loc_features): Make this static.
3031 * Makefile.in (libpath.h): Omit trailing slash from path. We
3032 shouldn't require it of users, so why put it here?
3034 Move code to initialize and search %load-path from ice-9 to C
3035 code, so we can use the load-path to find the ice-9 boot code;
3036 this makes it easier to run Guile without installing it. See
3037 corresponding changes in guile/Makefile.in.
3038 * feature.c: Move stuff concerned with the load path to load.c.
3039 (scm_compiled_library_path): Deleted.
3040 Don't #include libpath.h here.
3041 * feature.h: Don't mention scm_compiled_library_path.
3042 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
3043 <sys/stat.h>, and <unistd.h> (if present).
3044 (R_OK): #define if the system hasn't deigned to.
3045 (scm_loc_load_path): New variable.
3046 (scm_init_load_path, scm_sys_search_load_path,
3047 scm_sys_try_load_path): New functions.
3048 (scm_init_load): Initialize scm_loc_load_path to point to the
3049 value cell of the Scheme %load-path variable.
3050 * load.h: Add declarations for scm_sys_search_load_path,
3051 scm_sys_try_load_path.
3052 * init.c: Call scm_init_load_path.
3053 * Makefile.in (feature.o, load.o): Dependencies updated.
3055 * load.c, load.h: Rewrite using PROTO macro.
3057 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3059 * gc.c (scm_cellp): New function: C predicate to determine if an
3060 SCM value can be regarded as a pointer to a cell on the heap.
3062 * gc.h: Added declaration of scm_cellp.
3064 * gdb_interface.h: New file: The GDB interface header from the GDB
3067 * gdbint.c: New file: GDB interface.
3069 * gdbint.h: New file: GDB interface.
3071 * libguile.h: Added #include <libguile/gdbint.h>.
3073 * init.c (scm_boot_guile): Added scm_init_gdbint.
3075 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
3076 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
3077 found if object files and source are kept separate).
3079 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
3081 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
3083 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
3085 * configure.in: Don't substitute the values of TCL_SRC_DIR and
3086 TK_SRC_DIR; they're not relevant any more.
3088 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
3089 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
3091 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
3093 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
3094 search path, so we can find the <libguile/MUMBLE.h> headers.
3096 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
3098 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
3099 implicit in the .c.o rule.
3100 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
3103 Put the library path in a header file, instead of passing it on
3104 the command line in every compilation.
3105 * Makefile.in (libpath.h): New target.
3106 (feature.o): Depend on libpath.h.
3107 (clean): Delete libpath.h.
3108 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
3109 * feature.c: ... #include "libpath.h" here.
3110 * .cvsignore: Ignore libpath.h.
3112 Don't install the unwashed masses of Guile header files in the
3113 main #include path; put most of them in a subdirectory called
3114 'libguile'. This avoids naming conflicts between Guile header
3115 files and system header files (of which there were a few).
3116 * Makefile.in (pkgincludedir): Deleted.
3117 (innerincludedir): New variable; this and $(includedir) are enough.
3118 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
3119 (installed_h_files): Divide this up. Now this variable lists
3120 those header files which should go into $(includedir) (i.e. appear
3121 directly in the #include path), and ...
3122 (inner_h_files): ... this new variable says which files appear in
3123 a subdirectory, and are referred to as <libguile/mumble.h>.
3124 (h_files): List them both.
3125 (install): Create innerincludedir, not pkgincludedir. Put
3126 the installed_h_files and inner_h_files in their proper places.
3127 (uninstall): Corresponding changes.
3128 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3129 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3130 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
3131 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
3132 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
3133 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3134 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3135 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3136 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3137 vports.h, weaks.h: Find __scm.h in its new location.
3138 * __scm.h: Find scmconfig.h and tags.h in their new locations
3139 (they're both "inner" files).
3141 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
3143 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
3145 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3147 * posix.c: Doc fixes.
3149 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
3151 * socket.c: Don't include a prototype for inet_aton; just use a
3152 K&R style declaration, to avoid warnings but minimize the chance
3153 of conflicts with the system.
3155 On NextStep, <utime.h> doesn't define struct utime, unless we
3156 #define _POSIX_SOURCE before #including it.
3157 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
3158 * acconfig.h: New comment text for above CPP symbol.
3159 * configure.in: Call it.
3160 * posix.c: #define _POSIX_SOURCE if it seems necessary.
3162 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
3164 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
3165 testing for __EMX__.
3167 * posix.c: #include <libc.h>, if it exists.
3169 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
3170 don't even know if the latter exists.
3172 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
3173 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
3174 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
3176 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
3178 (scm_init_posix): Use them when initializing the Scheme constants
3181 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3183 * Makefile.in (libdir, includedir, bindir): Use the
3184 autoconf-supplied values, instead of deriving them ourselves.
3185 (pkgincludedir, datadir, pkgdatadir): New variables.
3186 (install, uninstall): Put the header files in a special
3187 subdirectory, not in the main search path.
3189 * Makefile.in (ALL_CFLAGS): Provide the proper value for
3190 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
3192 * Makefile.in (IMPLPATH): Deleted; never used.
3194 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
3195 on the Tcl/Tk source any more.
3196 (INCLUDE_CFLAGS): Remove references to the above.
3198 * Makefile.in (version.o): Corrected dependencies.
3200 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
3202 * libguile.h: #include "version.h"
3204 * init.c (scm_boot_guile): Call scm_init_version.
3205 * gscm.c (gscm_run_scm): Call scm_init_version.
3207 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
3208 GUILE_VERSION): AC_DEFINE these.
3209 (acconfig.h): #undef the above symbols.
3211 * Makefile.in (libobjs): Add version.o.
3212 (installed_h_files): Add version.h.
3213 (c_files): Add version.c.
3214 (gen_c_files): Add version.x.
3215 (version.o): New rule.
3216 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
3217 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

3225 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
3226 weaks.o): Add version.h to dependency lists.
3227 (markers.o): Remove duplicate rule.
3229 * version.h: New file.
3231 * version.c: New file.
3233 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3235 * symbols.c (scm_strhash): scm_downcase is now a function, not an
3236 array; use it appropriately. Since GCC is quite happy to
3237 subscript functions, it never warned us about this; we should use
3238 -Wpointer-arith in the future. I guess we never tested
3241 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3243 * socket.c: Doc and copyright fixes.
3245 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3247 * debug.c: Fixed and improved gdb support.
3249 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3251 * socket.c: Added declaration of inet_aton to avoid compiler
3252 warning. (Hope this solution is correct.)
3254 * stime.c: Added declaration of ftime. (This is missing in
3257 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
3259 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3261 * Makefile.in (c_files): add strerror.c.
3263 * strerror.c: new file from Emacs' sysdep.c.
3264 maybe configure should also check for sys_errlist.
3266 * configure.in (AC_REPLACE_FUNCS): add strerror.
3268 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3270 * debug.c (scm_init_debug): Added initialization for
3271 scm_evaluator_traps.
3273 * debug.h, debug.c: Various name changes.
3274 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
3275 "debug-options-interface". See commentary in options.c.
3277 * options.h, options.c: Options now have documentation strings.
3278 Also added a long explanatory commentary.
3280 * eval.c, print.h, print.c, read.h, read.c: Modifications to
3283 * gscm.c, init.c, root.c, throw.c: Bug fixes:
3284 last_debug_info_frame is now updated in all cases.
3286 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
3289 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3291 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
3292 Added option STACK_CHECKING.
3294 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3296 * Makefile.in: Added {debug,options,srcprop}.{h,c}
3298 * __scm.h: Removed symbols for debugging support.
3300 * acconfig.h: Added symbols for debugging support.
3302 * configure.in: Added user option for debugging support.
3303 --enable-debug will include the debugging code into libguile.a.
3305 * continuations.c (scm_make_cont): Enlarged the #if 0 around
3306 scm_relocate_chunk_to_heap.
3308 * debug.c: New file: low-level debugging support. It also
3309 includes support for debugging with gdb. (The extensions to gdb
3310 are written by Per Bothner at Cygnus.)
3312 * debug.h: New file: low-level debugging support.
3314 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
3315 argument pairs. Extensive modifications to the debugging
3316 evaluator. Added "SECTION:" commentaries to clarify what happens
3317 when, during double compilation. Renamed EVALIMP --> EVALIM.
3318 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
3319 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
3320 the beginning of the file. New procedure: scm_unmemocopy.
3321 Added some global state variables needed by the debugging
3322 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3323 check_entry, check_apply, check_exit, debug_options and
3324 evaluator_traps. New acro: undefine.
3326 * eval.h: Renamed EVAL --> XEVAL.
3328 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3329 --> scm_make_weak_key_hash_table.
3331 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3332 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3334 * libguile.h: Conditionally include debug.h
3336 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3337 scm_object_properties shouldn't return handle. `handle' now gets
3338 initialized in scm_set_object_properties_x. scm_object_properties
3339 doesn't any longer create an entry in scm_object_whash.
3341 * options.c: New file: handling of run time options.
3343 * options.h: New file: handling of run time options.
3345 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
3347 * print.c: New procedure: scm_print_options
3349 * print.h: Defines for print options.
3351 * read.c: New procedure: scm_read_options
3353 * read.h: Defines for reader options.
3355 * root.h: Added scm_source_whash among scm_sys_protects.
3357 * srcprop.c: New file: source properties.
3359 * srcprop.h: New file: source properties.
3361 * throw.c (jbsmob): Jump buffers are now correctly allocated.
3362 (Bug found by A. Green.)
3364 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3366 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3368 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3370 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3372 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3373 and should be called by the final client.
3375 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3377 * gc.h: Use the PROTO macro when declaring functions.
3378 * gc.c: Use the PROTO macro when declaring static functions.
3379 Remove the CPP hair around function definitions.
3381 * gc.c (scm_init_storage): Initialize scm_asyncs.
3383 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3384 preprocessor symbol; "__scm.h" is where it might get #defined.
3385 * __scm.h: Similar: #include <scmconfig.h> before testing
3388 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3390 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3392 * init.c (scm_boot_guile): Add init_func argument; call
3393 (*init_func) instead of calling scm_appinit; it's ucky to
3394 hard-code names for the user's procedures.
3395 * init.h (scm_boot_guile): Adjust declaration.
3397 * __scm.h (PROTO): New macro, for declaring functions with
3400 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3401 eliminate all the __STDC__ conditionals.
3402 (scm_boot_guile): Add declaration.
3403 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3404 Remove __STDC__ conditionals around function definitions; the
3405 declarations in init.h will provide the same information, more
3408 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3409 complain about it in the error message; the error message is
3410 adequate without that note, and there's nothing the user can do
3413 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3415 * Makefile.in (ancillary): Drop def.sed.
3417 * posix.c (scm_init_posix): Use numeric values, rather than
3418 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3419 F_OK. The symbols aren't available on some systems, and I'm
3420 pretty sure their values are fixed by common widespread practice.
3421 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3423 More functions unavailable on some systems.
3424 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3425 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3427 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3428 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3429 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3430 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3431 stub that signals an error as the #else.
3433 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
3435 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
3437 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
3439 * unif.c: include ramap.h.
3441 * read.c (endif): case_insensative_p renamed case_insensitive_p.

3445 * ports.c: include sys/ioctl.h.
3447 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
3449 * configure.in: check for sys/ioctl.h.
3451 * ports.c: include <malloc.h> not "malloc.h".
3453 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3455 * fports.c: remove ttyname and tmpnam declarations.
3457 * posix.c: fewer ttyname declarations.
3459 * fports.c: include <string.h> not "string.h".
3461 * init.c, ioext.c: include string.h and unistd.h.
3463 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3465 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
3466 genio.c, simpos.c, vports.c: include string.h.
3468 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
3470 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
3472 (scm_addr_buffer_size): change type from scm_sizet to int.
3473 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
3474 from scm_sizet to int.
3476 * error.c: include unistd.h.
3478 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
3481 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
3483 * __scm.hd, def.sed: deleted.
3485 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
3487 Changes for NeXT, suggested by Robert Brown.
3488 * configure.in: Call AC_TYPE_MODE_T.
3489 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
3490 NeXT. Put header file list in alphabetical order.
3491 * configure, scmconfig.h.in: Regenerated.
3492 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
3494 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
3497 * acconfig.h: New file, providing documentation for the CPP
3498 symbols defined in configure.in
3499 * acconfig-1.5.h: Removed; superceded by the above.
3501 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
3503 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
3505 * fports.c (scm_open_file): don't return #f, throw error.
3507 * ioext.c (fileno): renamed from %fileno.
3508 (soft-fileno): deleted.
3510 * ports.c (scm_port_revealed): don't need to check for -1 from
3512 (scm_set_port_revealed_x): return unspecified, not #f.
3514 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3516 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3518 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3520 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3522 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3524 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3525 This is necessary on Ultrix, and doesn't hurt portability.
3527 * Makefile.in (dist-dir): New target, implementing a new dist system.
3528 (installed_h_files): Put in alphabetical order.
3529 Remove duplicate entries for markers.h and unif.h.
3530 (c_files): Remove duplicate entries for markers.c.
3531 (ancillary): Renamed from anillery; all uses changed. Remove
3532 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3533 Remove all the ../doc/* files; doc/Makefile.in handles that.
3535 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3537 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3538 every if must have an else, or else the whole command has a
3539 non-zero exit code whenever the if's condition is false.
3541 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
3543 * posix.c: include string.h.
3545 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3547 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
3550 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
3551 Remove leading % from scheme names.
3552 Do not return error values, call SCM_SYSERROR or similar.
3554 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
3556 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
3558 * struct.c (scm_init_struct): new file.
3560 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
3562 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
3563 (scm_list_head): added list-head for rapidly chopping argument
3564 lists off of longer lists (and similar).

3568 * objprop.c (scm_object_property): assq the cdr of the whash
3569 handle for obj, not the handle itself.
3571 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
3573 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
3574 weak hash tables last of all marking to avoid an obscure gc bug.
3575 WARNING: circular lists stored in a weak hash table will hose us.
3577 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
3579 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
3580 new functions similar to scm_substring_move_left_x and
3581 scm_substring_move_right_x.
3583 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
3585 * init.c (scm_boot_guile): prevent gc with scm_block_gc not

3590 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
3592 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
3594 * strports.c (scm_strprint_obj): convenience function. C for
3595 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
3597 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
3598 removed to a separate library
3600 * init.c (scm_boot_guile): copied from guile-tcl.c.
3601 Initialization specific to tcl interpreters removed.
3603 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
3605 * ports.c (scm_ports_prehistory): size malloced here doesn't
3606 matter so long as it is non-0 (got rid of "* 4").
3608 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3610 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3611 since its definition was bogus).
3613 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3615 * mallocs.[ch]: back again (for rx at least).
3617 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3619 * ports.c: removed functions relating to the mapping between ports
3620 and descriptors. (That stuff is unix-specific and should be collected
3621 in a separate library).
3623 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
3624 (Tom Mckay@avanticorp.com)
3626 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
3628 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3629 handled correctly (SCM_FREEP was applied to them) -- test for
3630 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
3631 being overwritten with #f. (brown@grettir.bibliotech.com)
3633 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
3635 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

3638 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
3640 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak

3645 * list.c (scm_last_pair): map '()=>'()
3647 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>

3650 Generalized assoc and hash-table functions.
3651 Factored pairs.c into multiple files.
3653 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
3655 * gscm.c (gscm_run_scm): got rid of objprop.
3657 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
3659 * genio.c (scm_getc):
3660 NOTE: fgetc may not be interruptable.
3662 * procprop.c (scm_stand_in_scm_proc):
3663 NOTE: don't use a alist here.
3664 (scm_set_procedure_properties_x): fix type checking throughout this file.
3666 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
3668 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
3669 after freeing part of the port table.

3673 * strports.c (scm_mkstrport):
3674 * vports.c (scm_make_soft_port): allocate a port table entry
3675 (possibly triggering gc) before setting the tag of the corresponding
3678 * pairs.c (scm_delq_x): never throw an error.
3680 * vectors.c (scm_make_vector): made the default vector fill argument
3681 into '() (much more useful than the previous value, "#unspecified")
3683 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
3685 * ports.c (scm_add_to_port_table): Added fields
3686 to port table entries: file_name, line_num, col.
3687 Update these in open_file, gen_getc and gen_ungetc.
3688 Added procedures to access those fields.
3690 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
3692 * procs.c (scm_make_subr_opt): new entry point for making
3695 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
3697 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
3699 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
3701 * numbers.c (scm_exact_p): This function no longer
3702 implements "integer?".

3706 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
3707 (scm_gc_stats): return an assoc of useful data. Replaces "room"
3708 and the stats reporting formerlly built into repl.

3711 GC statistics keeping moved to gc.c.
3712 Other statistics keeping can be done from Scheme.
3713 REPLS are now written in Scheme.
3715 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
3717 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky

3720 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
3722 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
3724 * feature.c (scm_compiled_library_path): moved here from repl.c.
3725 This file is for stuff relating specifically to Scheme libraries
3728 * eval.c (scm_m_define): don't give warning about redefinition, don't
3731 NOTE: this should throw a resumable exception with parameters --
3732 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
3734 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
3736 * error.c: scm_warn eliminated.

3748 between the call to procedurep and use.
3750 * error.c (scm_everr):
3752 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
3755 * strports.c: don't reveal the port's string to the caller
3756 because it changes size.
3758 (stputc stwrite): check/change the strings length with interrupts
3761 * objprop.c (scm_set_object_property_x &c): use the generic
3762 hashing functions and be threadsafe.
3764 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
3765 (per suggestion jaffer@gnu.ai.mit.edu).
3767 * mbstrings.c (scm_multi_byte_string): guard against argument list
3770 * strings.c (scm_make_string): loop cleanup
3772 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
3775 * weaks.c (scm_weak_vector): guard against argument list
3778 * variable.c (scm_builtin_variable): check for/make a built-in
3781 * vectors.c (scm_vector): while filling the new array,
3782 guard against a list of fill elements that grows after
3783 the vector is allocated.
3785 * hashtab.c -- new file: general hash table
3786 functions. hash, hashq, hashv, hashx.
3788 * tags.h: made wvect an option bit of vector.

3792 * symbols.c: made the basic symbol table operations atomic.
3794 * root.c &c.: collected stack-specific global state.
3795 linum/colnum etc *should* be port-specific state.
3797 * struct.c (scm_init_struct): init the first struct type during
3798 initialization to fix a race condition.
3800 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
3801 object, not in a global.
3802 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
3804 * throw.c (_scm_throw): Pass throwval on the stack, not in a global
3805 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
3807 * *.[ch]: namespace cleanup. Changed all (nearly) exported CPP
3808 and C symbols to begin with SCM_ or scm_.
3810 Sun Feb 18 15:55:38 1996 Tom Lord <lord@beehive>
3812 * gsubr.c (scm_gsubr_apply): statically allocate the
3813 array of arguments (bothner@cygnus.com).
3815 Sat Feb 17 20:20:40 1996 Tom Lord <lord@beehive>

3819 * async.c: New support for interrupt handlers.
3821 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
3823 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
3824 set the multi_byte flag correctly in symbols. This is wrong.
3825 intern_obbary_soft and msymbolize should take an extra parameter.
3826 Also, weird multibyte symbols don't print correctly.
3827 The weird symbol syntax is also a bit bogus (emacs doesn't quite
3830 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
3832 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
3833 use the system symhash. == #t means create an uninterned symbol.
3835 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
3837 * strings.c (scm_make_shared_substring): build'em.
3838 It might better to keep a table of these and use one
3839 less cons-pair per shared-substring.
3841 Tue Feb 6 17:45:21 1996 Tom Lord <lord@beehive>
3843 * strings.c (scm_string_shared_substring): create shared

3854 * hash.c (scm_hasher): hash RO and MB strings as bytestrings.
3856 * eval.c (SCM_CEVAL): self-evaluate RO and MB strings.
