7 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
8 throw.c: Update copyright years; these files have been worked on
9 significantly in 1997, but only had copyright years for 1996.
10 Also, change name of copyright holder on some from Mikael
11 Djurfeldt to Free Software Foundation; he has signed papers
12 assigning the changes to the FSF.
14 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
15 reason not to give the user the option.
17 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
18 Return #f on end-of-file when scanning table (i.e. when called

20 * posix.c (scm_getgrgid, scm_getpwuid): Same.
22 * script.h (scm_shell_usage, scm_compile_shell_switches): New
23 external declarations. These are useful.
25 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
27 * posix.c: don't include <sys/select.h> or define macros for
28 select, since they were not used in this file.
30 * filesys.c (scm_select): make the fifth parameter microseconds,
31 not milliseconds. let the fourth parameter be either a real value
32 or an integer or #f. The first, second and third arguments can
33 now be vectors: the type of the corresponding return set will be
35 (set_element, get_element): new static procedures.
37 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
39 * strports.c (scm_eval_string): New function.
40 (scm_eval_0str): Trivially re-implemented in terms of
42 * strports.h (scm_eval_string): New extern decl.
44 * net_db.c (h_errno): Add extern decl for this.
46 * fports.c (local_pclose): New function.
47 (scm_pipob): Use it in the initializer here.
50 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
51 Use a meaningful error message when signalling an error. For
52 this, scm_gethost must check h_errno rather than errno.
54 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
56 * Makefile.in: Regenerated, using automake-1.1p.

68 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
70 Ensure that shared substrings are handled properly when passed to
71 a system call or other foreign function. Many thanks to Tim
73 * symbols.h (SCM_COERCE_SUBSTR): new macro.

75 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
76 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

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

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

133 sure how this was supposed to work.
134 (scm_async_click): don't send SCM_TICK_SIGNAL.
135 (scm_init_async): don't initialize %tick-thunk.
137 * the following change doesn't affect the Scheme interface:
138 gc-thunk is called at the end of garbage collection. however it's
139 no longer implemented by pretending it's a signal.
141 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
142 system async corresponding to scm_gc_thunk.
143 * async.h: declare scm_gc_async.
144 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
145 gc-thunk directly, instead of going through a signal handler.
146 (scm_gc_async): new variable, points to the GC system-async.
147 (scm_init_async): save the GC async as scm_gc_async instead
148 of using system_signal_asyncs.
149 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
151 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
153 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
154 Don't screw up if we're interrupted.

157 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
159 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
161 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";

167 Functions for finding variable bindings, grace à Tim Pierce.
168 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
169 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
171 Get 'make dist' to work again.
172 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
173 * Makefile.in: Regenerated, like a surry without a fringe on top.
175 Changes for reduced Guile distribution: one configure script,
177 * configure.in, configure: Removed.
178 * acconfig.h, acinclude.m4: Moved to parent directory, where the
179 real configure script lives.
180 * Makefile.in, scmconfig.h.in: Regenerated.
182 * init.c: #include "script.h", to get prototype for script.c's
185 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
187 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
188 scm_must_malloc, not raw malloc.
190 * script.c (scm_compile_shell_switches): Dyke out debugging output
193 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
195 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
197 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
198 system has them. Hope this is safe. Previously
199 sys/timeb.h was included if HAVE_FTIME was defined or if
200 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
201 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
203 * ioext.c (scm_setfileno): add missing third argument to
206 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
208 * eq.c (scm_equal_p): Correctly compare strings of different

214 #! block comment must occur on a line all by itself.
216 Move most of the guts of shell command processing into libguile,
217 so guile.c can be very small (and eventuallly auto-generated. (I
218 mean, generated mechanically, not self-generated. Hmm.))
219 * guile.c, script.c, script.h: New source files.
220 * init.c (scm_boot_guile_1): Call scm_init_script.
221 * libguile.h: #include "script.h".
222 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
223 targets, for new executable.
224 (libguile_la_SOURCES): Mention script.c.
225 (modinclude_HEADERS): Add script.h.
226 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
227 not dynamic linking is enabled. This is because we're generating
228 executables now. Move CY_AC_WITH_THREADS call after those, so the
229 values of cy_cv_threads_libs captures the libs chosen above.
230 * Makefile.in, configure, aclocal.m4: Regenerated.
232 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
233 We don't maintain this interface any more, and it just confuses
236 * alloca.c: #include <scmconfig.h>, not <config.h>.
237 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
238 it'll get included in disties.
240 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
242 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
243 be distributed, because they confuse people.
244 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
246 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
248 * configure.in: check for presence of gethostent (not present on
250 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
251 * configure, scmconfig.h.in: Regenerated.
253 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
255 * backtrace.c (scm_backtrace): Split message string across
256 newlines properly. GCC is more tolerant of this than other
259 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
261 Merge threads directory into libguile.
262 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,

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

321 when PROC is receiving no arguments.
323 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
325 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
326 have S_IFSOCK. This is the case under Ultrix.
328 * posix.c (scm_status_exit_val, scm_status_exit_val,
329 scm_status_term_sig, scm_status_stop_sig): Modified to work with
330 Ultrix versions of WIFSTOPPED, etc., which assume that their
331 arguments are lvalues (hmm).
333 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
337 * throw.c: Doc fixes; rearranged.
339 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
341 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
343 * acconfig.h: Added entry for PACKAGE.
344 * scmconfig.h.in: Regenerated.
346 Changes to work with automake-1.1n, which has better libtool support.
347 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
348 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the

361 (bdtime2c, setzone, restorezone): new static procedures.
362 (scm_mktime, scm_strftime): use them.
363 (scm_strftime): don't call mktime before strftime. Use
364 filltime for return value.
365 (filltime): convert NULL zname to #f.
366 (scm_strptime): return a count of characters consumed, not
367 the remaining string.
369 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
371 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
372 (scm_mktime): likewise.
374 Uncomment localtime and mktime.
376 * configure.in: add AC_STRUCT_TIMEZONE.
378 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
380 * stime.c (scm_init_stime): don't define ticks/sec.
381 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
382 return value problem and is still portable.)
384 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
386 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
387 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
388 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
389 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
390 cpp_err_symbols.c): Corresponding changes.
391 * Makefile.in: Regenerated.

396 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
397 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
398 * putenv.c: new file, from sh-utils 1.12.
400 * posix.c (scm_environ): use malloc in place of scm_must_malloc
401 since allocation isn't for Scheme objects.
402 (scm_putenv): copy strings before placing in the environment.
404 * stime.c (scm_current_time): throw an error if time returns -1,
405 instead of returning #f.
406 (scm_get_internal_real_time, scm_get_internal_real_time): use
407 scm_long2num for return value instead of SCM_MAKINUM.
409 * stime.h: prototypes updated.
411 * stime.c (scm_time_in_msec): apparently unused, deleted.
413 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
415 * configure.in: check for gettimeofday.
417 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
418 which may be more usefully portable than a gettimeofday interface.
420 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
422 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
424 * Makefile.in: Regenerated.
426 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
428 * stime.c (filltime): recovered static procedure.
429 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
432 * posix.h: add prototype for scm_close_pipe, remove prototypes for
433 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
435 * posix.c (scm_mknod): split the mode argument into type and perms
436 arguments, like the extra fields returned by stat.
438 * fports.c (scm_pipob): set the close, free and print procedures.
439 (scm_close_pipe): new procedure.
441 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
442 define them in boot-9.scm
444 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
446 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
447 wan't defined. Don't include fd.h.
449 * Previously fd.h was regenerated whenever configure was run,
450 forcing a couple of files to be recompiled.
452 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
453 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
454 Check for _fileno as well as _file.
456 * ioext.c: don't fd.h.
457 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
460 * Change the stratigy for getting information about errno
461 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
462 generating lists of symbols during the build process, which will
463 not always work, include comprehensive lists in the distribution.
464 To help keep the lists up to date, the "check_signals" and
465 "check_errnos" make targets can be used.
467 * configure.in: don't check for a command to extract errno codes.
468 * Makefile.am: update file lists, remove errnos.list and errnos.c
469 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
470 check_errnos targets.
471 (CLEANFILES): remove errnos.c and errnos.list, add
472 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
473 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
474 * errnos.default: deleted.
475 * cpp_signal.c: new file.

477 * cpp_err_symbols, cpp_sig_symbols: new files.
478 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
479 * error.c (scm_init_error): #include cpp_err_symbols instead of
481 * posix.c (scm_init_posix): don't intern signal symbols. #include
484 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
486 * strop.c (scm_i_index): allow the lower bound to be equal to the
487 length of the string, so a null string doesn't always give an error.
489 * posix.h: new prototypes.
490 * posix.c (scm_status_exit_val, scm_status_term_sig,
491 scm_status_stop_sig): new functions, as in scsh. They break down
492 process status values as returned by waitpid.
494 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
496 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
497 configure doesn't know about it.
499 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
501 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
503 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
504 which defines C variables with global linkage.
506 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
508 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
511 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
513 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
514 has time to check why this doesn't work well with continuations.
516 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
518 * Fix shell syntax error; some shells won't tolerate
519 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
521 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
523 * posix.c (scm_uname): throw an error if uname fails instead
526 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
528 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
531 * async.c (scm_ints_disabled): definition moved from error.c.
533 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
535 * acconfig.h: Removed PACKAGE.
537 * scmconfig.h.in: Regenerated.
539 * snarf.h: g++ says it's non-portable not to specify the first
540 argument in a varargs declaration. I introduced the first
541 argument by using preprocessor conditionals.
543 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
545 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
546 (scm_freopen): use RO string macros for filename and modes.
547 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
549 * posix.c (scm_getgrgid): simplify conversion of name to C string.
550 (scm_mknod): use RO string macros for path.
552 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
553 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
555 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
556 use SCM_ROSTRINGP and SCM_ROCHARS.
558 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
560 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
563 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
564 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
565 support for byte vectors.
567 * print.c (scm_iprin1): Limit number of vector elements printed
568 according to pstate->length.
570 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
572 * backtrace.c (scm_display_error_message): don't segv if message
575 * error.h: prototype for scm_error_scm.
577 * error.c (scm_error_scm): new procedure, reimplements scm-error
578 in C and uses scm_error.
580 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
582 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
583 pointer to the Scheme variable read-hash-procedures and intern it
584 in scm_init_read. Modify scm_read_hash_extend and
585 scm_get_hash_procedure to use the pointer.
587 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
589 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
590 (SCM_KEYWORD_STYLE): defined.
592 * read.c (scm_read_opts): add a keywords option. This isn't a
593 boolean option, in case someone wants to add support for DSSSL
595 Setup scm_keyword_prefix symbol.
596 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
598 I've left keyword support disabled by default, since it doesn't
599 seem to break the module system and it gives R4RS standard behaviour.
600 It can be reactivated with (read-set! keywords 'prefix).
602 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
604 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
605 before constructing arbiter.
607 * eval.c (scm_m_define): Bugfix: Check that the object is a
608 closure before setting the procedure property!
610 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
612 * ports.c: Removed `ungetc-char-ready?'.
614 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
616 * read.c (scm_init_read): intitialise scm_read_hash_procedures
617 (idea from Mikael: make it a pair so scm_permanent object only
619 (scm_read_hash_extend): don't call scm_permanent_object.
620 (ideas from Mikael): if chr is already in the list, replace its
621 procedure instead of appending it again. If proc is #f, remove
623 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
625 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
627 * gdbint.c (gdb_read): update scm_lreadr usage.
629 * load.h: update prototypes.
631 * load.c (scm_primitive_load, scm_read_and_eval_x,
632 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
634 * read.h: add prototype for scm_read_hash_extend. Change args for
637 * read.c (scm_read_hash_procedures): new variable.
638 (scm_read_hash_extend): new procedure.
639 (scm_get_hash_procedure): new procedure.
640 (scm_lreadr): use scm_get_hash_procedure instead of an argument
641 for extended # processing.
642 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
643 scm_read_token): remove case_i, sharp arguments. Change callers.
645 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
647 * read.h (SCM_N_READ_OPTIONS): increase to 3.
648 (SCM_CASE_INSENSITIVE_P): define.
650 * read.c: add case-insensitive option to scm_read_opts.
651 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
652 to determine whether to convert symbol case.
653 (default_case_i): definition removed.
654 * read.c (scm_read_token): if case_i, downcase ic before doing
657 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
659 * configure.in: Added configuration option `guile-debug'.
660 Configure with --enable-guile-debug if you want a bunch of extra
661 functions used for debugging when developing Guile.
663 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
665 * procs.c (make-cclo): New undocumented debugging procedure: Make
666 compiled closure with internal procedure PROC and length LENGTH.
667 Only compiled if GUILE_DEBUG is defined.
669 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
671 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
673 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
675 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
676 with 3 or more args internally to the evaluator.
678 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
680 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
681 with 3 or more args internally to the evaluator. This is mainly
682 because we don't want to pass entry and exit points of the
683 debug support twice, but it also seems to increase the speed of
684 the evaluator for such calls (e. g. (+ 1 2 3)).
686 * backtrace.c (scm_display_application): New procedure:
687 display-application; Set fancy printing parameters individually
688 for different types of display (backtrace, error, application).
689 (These should of course be customizable!)
691 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
692 clear the CHECK-flags.
694 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
696 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
698 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
700 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
701 from pairs with a GLOC in the car.
703 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
704 otherwise `symbol-hash' will behave badly.
705 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
706 we get segmentation fault!
708 * symbols.c: Added #include "weaks.h". New functions:
709 `builtin-bindings' and `builtin-weak-bindings'. (These will be
710 moved to an extraneous library when we split libguile.)
712 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
714 * filesys.c (scm_stat): stat now takes fport arguments too as
715 documented in the manual.
717 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
719 * debug.c (scm_single_step): Bugfix: Call continuation with
720 scm_call_continuation instead of throwing to it.
722 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
724 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
725 argument wasn't declared to be optional.
727 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
729 * stime.c (scm_init_stime): Add feature "current-time".
731 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
733 * throw.h: prototype for scm_exit_status.
734 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
735 args to derive an exit status. Allows (quit) to work from a
737 (scm_exit_status): new function.
740 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
742 * eval.c (scm_deval): Removed some old code.
743 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
745 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
748 * symbols.c (msymbolize): Bugfix: Must initialize property list to
751 * procs.c: Introduce the existent C function scm_thunk_p at the
752 Scheme level as well.
754 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
756 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
757 used from C to easily lookup the value of a symbol in the current
760 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
762 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
763 scm_init_unif in this file. This will also fix a previous problem
766 * configure.in: Added AM_MAINTAINER_MODE
768 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
770 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
773 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
775 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
776 source files that are not always included in libguile but should
777 have their dependencies calculated by automake. This variable is
778 recognized by automake, no further magic is needed.
779 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
780 to deal exclusively with *.lo files, as it seems. The *.o files
781 are built automatically when the corresponding *.lo file gets
784 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
786 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
789 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
791 * unif.c (scm_array_set_x): minor change to argument error checking.
793 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
795 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
796 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
797 They should only be included in the library at configure.in's
799 (libguile_la_LDADD): Include the appropriate .lo files here.
800 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
801 so we know when to build them (and their .lo bretheren).
802 * configure.in (LIBLOBJS): New substituted variable. We let
803 configure decide which .o files to include in LIBOBJS, and then
804 put the corresponding list of .lo files in LIBLOBJS. The latter
805 is what we pass to libtool.
806 * Makefile.in, configure: regenerated.
808 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
810 * symbols.c (scm_sysintern0): New function. Contains the core of
811 old scm_sysintern but doesn't take a second value argument.
812 (scm_sysintern): Now uses scm_sysintern0.
813 (scm_sysintern_no_module_lookup): Renamed to
814 scm_sysintern0_no_module_lookup and doesn't take a second value
817 * symbols.h (scm_sysintern0: Added declaration.
819 * options.c (scm_init_opts): Use scm_sysintern0 instead of
820 scm_sysintern when interning option keys. Otherwise we risk
821 destroying the values of already interned variables.
823 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
824 scheme-level boolean (use SCM_NFALSEP).
826 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
828 (scm_backtrace): New function. (C version of old function from
829 boot-9.scm) Motivation: Make it possible to display backtraces
830 without depending on boot-9.scm. (I'm uncertain if this
831 motivation is good enough...)
833 * root.h (scm_root_state): Add member the_last_stack_var.
834 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
836 * root.c (mark_root): Mark scm_the_last_stack_var.
838 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
841 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
843 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
844 1. mark_lazy_catch didn't mark the smob.
845 2. Both functions above have standard variants:
846 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
847 free_lazy_catch --> scm_free0.
849 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
851 * throw.c (scm_internal_lazy_catch): New function.
852 (scm_lazy_catch): Rewritten to use it.
853 (scm_ithrow): Handle the new lazy catch representation.
854 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
855 that doesn't have a jmpbuf is a lazy catch clause.
856 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
857 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
858 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
860 (scm_init_throw): Register the new lazy-catch smob type.
861 * throw.h (scm_internal_lazy_catch): decl for new function.
863 * throw.c (scm_internal_catch): Doc fixes.
865 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
866 configure.in. Including this might cause problems if applications
867 that link against libguile include their own copies of alloca, but
868 if they're using autoconf, they should be adding libguile to LIBS
869 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
870 the copy in libguile, and things will be okay. (I think.)
872 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
874 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
876 strop.h: move prototypes too.
878 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
880 * posix.c (scm_init_posix): don't intern EINTR since it's now done
883 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
884 etc. I deleted them from filesys.c long ago, but didn't
885 notice they were here too (although ineffective since
886 sys/stat.h wasn't included).
888 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
890 * eval.c: Don't define alloca in GCC case. gcc will automatically
891 use __builtin_alloca if appropriate.
893 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
895 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
896 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
897 that values of automatic variables are preserved. See comments
898 for safe_setjmp for details.
900 Change from Thomas Morgan:
901 * variable.c: Include eq.h.
902 (var_equal): New function.
903 (variable_smob): Use var_equal as the discriminator for variables.
905 * throw.c (s_throw): Remove extraneous declaration.
907 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
908 * eval.c: Add necessary CPP cruft to support that.
909 * configure, Makefile.in, scmconfig.h.in: regenerated.
911 Change from Thomas Morgan:
912 * procprop.c (scm_procedure_properties): Convert the Scheme
913 boolean returned by scm_procedure_p into a C boolean before using
914 it as a condition for SCM_ASSERT.
915 (scm_procedure_property): Likewise.
917 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
918 indications of Unixness.
921 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
923 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
925 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
927 * read.c (scm_lreadr): use scm_misc_error to improve one of the
928 "unknown # object" error messages.
930 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
931 (scm_i_index) and declare it static. Add a 'direction' argument
932 to indicate what way the search should go.
933 (scm_i_index): throw out-of-range error instead of wrong-type-arg
935 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
936 strop.h: remove scm_i_index, scm_i_rindex prototypes.
938 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
940 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
942 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
943 to avoid clash with various scsh forks.
945 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
947 The following two changes (ramap.c, throw.c) are motivated by the
948 apparent unportability of forward declarations of static arrays of
949 the form `static foo bar[];'.
951 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
952 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
954 * throw.c (scm_throw): Moved above scm_ithrow.
956 * options.h: Removed the extern declarations of scm_yes_sym and
957 scm_no_sym since these are static.
959 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
961 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
963 * Makefile.am: remove AWK=@AWK@.
964 Add a rule for generating errnos.list.
965 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
967 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
968 don't extract errnos, just set a variable (avoids the
969 need to recompile error.c just because configure is run.)
971 * unif.h: update prototypes.
972 * unif.c (scm_uniform_array_read,write): change the offset and
973 length arguments to start and end, for consistency.
975 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
977 * ioext.h: update prototypes.
978 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
979 scm_read_line_x, it's a more general procedure using an
980 interface from scsh. read-line and read-line! are now defined
982 Note that the new read-line trims the terminator
983 by default, previously it was appended to the returned string. An
984 optional argument specifies how to process the terminator (scsh
985 compatible). For the old behaviour: (read-line port 'concat).
986 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
987 returns a pair, but is converted to multiple values if the scsh
990 socket.h: update prototypes.
991 * socket.c (scm_recvfrom): for consistency with other procedures,
992 take start and end as separate optional arguments.
993 (scm_recv, scm_recvfrom): don't allow the second argument
994 to be a size, only a buffer. Change the scheme names to
995 recv! and recvfrom!. Don't return the buffer.
997 * ioext.h, posix.h: move prototypes too.
998 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
999 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
1000 "read.h" and "unif.h".
1001 * ioext.c: include "chars.h"
1003 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
1005 * dynl.c: The dynamic linking and module registration functions
1006 are now defined even when dynamic linking is not available for the
1007 host system. Some of their functionality can be done without
1008 dynamic linking; when it's really needed, they throw errors.
1010 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
1012 * configure.in: Only define DYNAMIC_LINKING when one of the system
1013 dependent functions is detected.
1014 * dynl.c (scm_dynamic_func): New function to get the address of a
1015 function in a dynamic object.
1016 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
1017 produced by scm_dynamic_func as the thing to call.
1019 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
1021 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
1022 (scm_register_module_xxx, scm_registered_modules,
1023 scm_clear_registered_modules): New functions.
1025 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
1027 * symbols.c (scm_sysintern): Renamed to
1028 scm_sysintern_no_module_lookup.
1029 (scm_sysintern): New function to take the place of the old
1030 scm_sysintern. It uses the current toplevel lookup closure to give
1031 the symbol its value. This is a temporary hack to put packages
1032 like gtcltk into their own module.
1033 (scm_can_use_top_level_lookup_closure_var): New variable to tell
1034 us whether `scm_top_level_lookup_closure_var' has been initialized
1036 * eval.c (scm_init_eval): Set it.
1038 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1040 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
1041 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
1043 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
1045 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
1046 scm_sys_dup): deleted: FD capability will be added to other
1048 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
1049 scm_fd_free, fd_smob, scm_intern_fd.
1050 (scm_open): renamed from scm_sys_open. Return a port instead of
1051 an FD object. Make the mode argument optional.
1052 (scm_sys_create): deleted, it's just a special case of open.
1053 (scm_init_filesys): move interning of constants O_CREAT etc.,
1054 here (were previously using SCM_CONST_LONG macro).
1055 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
1057 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
1058 include "fports.h" and <stdio.h>
1059 (scm_stat, scm_select): don't support FD objects.
1061 * error.h: adjust scm_syserror_msg prototype.
1062 * error.c (scm_syserror_msg): take an extra argument for errno.
1063 Using the global value didn't always work, since it could be
1064 reset by procedure calls in the message or args arguments.
1066 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
1067 I don't understand why the check was there (and what about the
1070 * strop.c (scm_string_copy): allow shared substrings to be copied.
1072 * unif.h: corresponding change to prototypes.
1073 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
1074 recognize two new optional arguments: offset and length. Allow
1075 the port argument to be an integer (file descriptor, for scsh).
1076 Include <unistd.h> for "read" prototype.
1078 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1080 * socket.c: don't include filesys.h.
1082 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
1084 * Makefile.am: add AWK=@AWK@ (?)
1086 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
1088 Add a rule to generate errnos.c from errnos.
1089 * error.c (scm_init_error): include errnos.c.
1090 * errnos_cnvt.awk: new file, converts the list of errno codes to
1092 * errnos_get.c: new file.
1093 * errnos.default: new file, contains errnos to try if they can't
1094 be extracted from errno.h.
1095 * configure.in: if using GCC, try and extract errno codes from
1099 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
1101 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
1102 * Makefile.am: Made libguile into a libtool library.
1103 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
1104 Set libtool_libs to indicate that libguile is a libtool library.
1105 See guile/ChangeLog for details.
1106 * .cvsignore: ignore "*.lo", the libtool library objects.
1108 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1110 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
1111 use htons in getservbyport argument.
1113 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1115 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
1116 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
1119 * objprop.c (scm_object_property): No need to take the CDR of the
1120 value returned by scm_object_properties, since Aug 20 change.
1122 * configure.in: When checking for struct linger, #include
1123 <sys/types.h> as well as <sys/socket.h>. I've never known
1124 <sys/types.h> to cause any portability problems, and Solaris's
1125 <sys/socket.h> needs it.
1126 * configure: Rebuilt.
1128 I think the Sun compiler has chosen a perverse way to interpret
1129 ANSI declarations combined with K&R definitions. We'll
1130 appease it a little bit. But when it invades France, we fight.
1131 * print.c (scm_iprlist): Change 'tlr' argument to an int.
1132 * print.h (scm_iprlist): Here too.
1133 * numbers.c (scm_divbigdig): Change definition to match
1134 declaration in numbers.h.
1135 * unif.c (scm_makflo): Change definition to match declaration in
1138 * init.c (scm_boot_guile): Don't return the value of
1139 scm_boot_guile_1. This function doesn't return a value;
1140 scm_boot_guile_1 doesn't return a value (or return at all).
1142 * eval.c (unmemocopy): Add a semicolon to appease the Sun
1145 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
1146 compile. I have a feeling this function is a bad idea anyway ---
1147 one should always test for features, not systems.
1149 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
1150 semicolons. Only pure luck kept this from being noticed earlier.
1152 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
1154 * socket.c (scm_recvfrom): Added missing semicolon.
1156 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1158 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
1159 the buffer and start and end positions for scsh networking
1162 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
1164 * configure.in: Revert previous change to this file; the problem
1165 is due to transient automake weirdness.
1166 * configure: Rebuilt.
1168 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
1169 PLUGIN/guile.libs. configure generates the latter from the former.
1170 * Makefile.in: Rebuilt.
1172 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
1173 need this if we install scripts, like guile-snarf.
1174 * configure: Rebuilt.
1176 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1178 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
1180 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
1182 * socket.c (scm_addr_vector): fix faulty scm_listify.
1184 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
1186 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
1187 style block comment is no longer considered an error.
1189 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
1191 * PLUGIN/guile.libs.in: New file.
1192 * PLUGIN/guile.libs: Removed from repository.
1193 * configure.in: Create PLUGIN/guile.libs from
1194 PLUGIN/guile.libs.in. This is for including additonal libraries
1195 needed for dynamic linking.
1196 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
1197 instead of PLUGIN/guile.libs.
1199 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
1201 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
1203 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
1204 occurrences of the given element from the list, not just the
1205 first. This is how the Emacs Lisp functions behave, how the
1206 analogous Common Lisp functions behave, and (I believe) how the
1207 older Maclisp functions worked. I realize that this change may
1208 break code, but it seemed better to break it before the Guile
1211 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
1212 Their prototypes were already present in gc.h, but they weren't
1214 (scm_init_storage): Initialize scm_protects.
1215 * root.c (scm_protects): New element of scm_sys_protects.
1217 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
1219 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1221 * libguile.h: Added #include "libguile/net_db.h".
1223 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
1224 30 change. That file is only meant for communication between the
1225 configuration process and load.c. If code linked against libguile
1226 wants to get at the paths mentioned in libpath.h, it can call
1227 functions declared in load.h.
1229 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1231 * libguile.h: Removed #include "libguile/fdsocket.h"
1233 * net_db.c: Added #include <sys/socket.h>.
1235 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
1237 * filesys.c (scm_input_waiting_p): use select in preference to
1238 FIONREAD, since the latter doesn't detect EOF.
1239 Throw error if neither select nor FIONREAD available.
1241 * socket.c (scm_connect): take a port, not a fd object.
1242 (scm_fill_sockaddr): throw an error if fam is not recognised.
1243 (scm_bind): use scm_fill_sockaddr.
1244 (scm_listen): take a port, not a fd object.
1245 (scm_accept): take and return a port. return #f in the car if
1246 address can't be got
1247 (scm_sock_fd_to_port): new procedure.
1248 (scm_socket): use scm_sock_fd_to_port.
1249 (scm_addr_vector): throw error if unrecognised address type.
1250 take an extra argument with the calling procedure name.
1251 (scm_getsockname): take a port. return #f if address can't be got.
1252 (scm_getpeername): take a port. return #f if address can't be got.
1253 (scm_recvfrom): take a port. return #f for address component if can't
1255 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
1256 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
1258 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
1260 * throw.c (scm_internal_catch): Make body funcs and handler funcs
1261 use separate data pointers, to allow them to be designed
1262 independently and reused.
1263 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
1264 Renamed from catch_body, catch_handler, and uncaught_throw; made
1266 (struct scm_catch_body_data): Renamed from catch_body_data; moved
1268 (scm_catch): Use the above.
1269 (scm_throw): Don't bother printing a message for an uncaught
1270 throw; we establish a default handler in init.
1271 * throw.h (scm_internal_catch): Prototype updated.
1272 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
1274 (struct scm_body_thunk_data): New structure, used as data
1275 argument to scm_body_thunk.
1276 * init.c (struct main_func_closure): New structure, packaging up
1277 the data to pass to the user's main function.
1278 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
1279 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
1280 scm_internal_catch to establish a catch-all handler, using
1281 scm_handle_by_message. This replaces the special-case code in
1283 (invoke_main_func): Body function for scm_internal_catch; invoke
1284 the user's main function, using the main_func_closure pointer to
1285 decide what to pass it.
1286 * root.c (struct cwdr_body_data): Remove handler_proc member.
1287 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
1288 (cwdr_handler): Removed.
1290 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1292 * socket.h (SCM_P): update bind prototype.
1293 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
1294 include "feature.h".
1295 (scm_socket): return a port, not a file descriptor object.
1296 include "fports.h" and <unistd.h>
1297 (scm_bind): take a port, not a file descriptor object.
1298 take an extra argument for address args.
1300 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
1301 INADDR_NONE, INADDR_LOOPBACK.
1303 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1305 * init.c: include net_db.h and not fdsocket.h.
1306 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
1308 * Makefile.am: corresponding changes.
1309 * socket.h: renamed from fdsocket.h, fix names.
1310 * net_db.h: renamed from socket.h, fix names.
1311 * socket.c: renamed from fdsocket.c.
1312 remove _sys from procedure names.
1313 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
1314 add "socket" to features list.
1315 * net_db.c: renamed from socket.c.
1316 remove _sys from procedure names.
1317 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
1318 add "net-db" to features list.
1319 include "net_db.h". don't include <sys/socket.h> or
1322 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1324 * tags.h (scm_tags): Removed comma at end of last enumerator.
1326 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
1328 Don't use GCC extensions to allocate space for debugging frames.
1329 (Here he goes again! Why do we put up with this?!)
1330 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
1331 an scm_debug_info structure, not an in-line array of them. Add
1332 'info' member, to say how many vect elements we've used, for eval
1334 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
1335 a new variable debug_info_end to mark the end of vect, instead of
1336 the address of the 'info' pointer itself.
1337 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
1338 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
1339 (SCM_APPLY): Explicitly allocate space for debug.vect.
1340 * debug.c (scm_m_start_stack): Same, for vframe.vect.
1341 * stacks.c: Adjusted for new debug frame structure.
1342 (RELOC_INFO, RELOC_FRAME): New macros.
1343 (stack_depth, read_frames): Use them, and new scm_debug_frame
1344 element 'info', instead of magically knowing that eval frames have
1345 an info pointer sitting after vect.
1346 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
1348 (scm_init_stacks): Formatting tweaks.
1350 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
1352 Give GCC more control flow information, so it can be sure that
1353 variables aren't used uninitialized.
1354 * error.h (scm_error, scm_syserror, scm_syserror_msg,
1355 scm_sysmissing, scm_num_overflow, scm_out_of_range,
1356 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
1357 scm_misc_error): Tell GCC that these functions never return.
1358 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
1359 out the field type, call abort if SCM_ASSERT returns, to placate
1361 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
1362 scm_wta ever returns. We can't handle this case anyway, and this
1363 gives the optimizer more information.
1364 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
1365 scm_wta ever returns.
1367 In some cases, the code is fine, but GCC isn't smart enough to
1368 figure that out; this usually happens when one variable is only
1369 initialized and used when a particular condition holds true, and
1370 we know that condition will never change within a given invocation
1371 of the function. In this case, we simply initialize the variables
1372 to placate the compiler, hopefully to a value which will cause a
1373 crash if it is ever actually used.
1374 * print.c (scm_iprin1): Initialize mw_pos.
1375 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
1376 * throw.c (scm_ithrow): Initialize dynpair.
1377 * unif.c (scm_uniform_vector_ref): Initialize cra.
1378 * struct.c (init_struct): Initialize prot.
1379 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1381 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1382 if EXPR contains no expressions.
1384 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1386 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1387 cause an infinite loop (???). So much for the algebraic
1388 equivalency of variable-sized arrays and alloca...
1390 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1392 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1393 a SCM boolean, not a C boolean.
1395 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1397 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1398 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1399 rules for raising scm_mtrigger. Previously, unfortunate but not
1400 unlikely circumstances could result in almost constant invokation
1401 of the gc. Now, this situations should be less likely, but they
1402 are not prevented completely.
1404 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1406 * numbers.c (scm_fuck): Procedure removed; looks like old test
1408 * numbers.h: Prototype removed.
1410 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1412 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1413 array to a pointer, to match my Nov 21 change in eval.c.
1415 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1417 * libguile.h: Added #include "libguile/backtrace.h", #include
1418 "libguile/stacks.h".
1420 * strings.c (scm_string scm_make_string scm_string_ref
1421 scm_string_set_x scm_string_equal_p scm_string_append):
1422 Bugfix according to scm patch from Aubrey Jaffer:
1423 Corrected long-standing
1424 (not (eqv? (integer->char 128)
1425 (string-ref (make-string 1 (integer->char 128)) 0)))
1426 bug found by John Kozak <jk@noontide.demon.co.uk>.
1428 * strports.c, strports.h: Make scm_eval_0str return the value of
1429 the last expression evaluated (previously, it returned void).
1431 * strports.c, strports.h: New function: scm_read_0str. Does what
1434 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1436 * simpos.c (scm_getenv): return #f if string can't be found in the
1437 environment instead of throwing an exception, for compatibility
1438 with numerous other systems.
1440 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1442 * Makefile.am (.c.x): Use guile-snarf.
1443 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1445 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1447 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1449 * backtrace.c (scm_display_error_message): Made non-static, and
1450 renamed from display_error_message.
1451 * backtrace.h (scm_display_error_message): Added extern decl.
1452 * throw.c (uncaught_throw): Use it to display the error message.
1454 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1456 * inet_aton.c: Use #if 0, not #ifdef 0.
1458 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1460 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1461 to convert the returned value.
1462 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1463 the offset argument.
1465 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1467 Add new interface to catch/throw, usable from C as well as
1469 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1470 (scm_internal_catch): New function, replaces...
1471 (scm_catch_apply): Deleted.
1472 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1473 mechanism which is a bit more code, but can be used nicely from C
1474 and implement the Scheme semantics as well.
1475 (scm_internal_catch): This is the replacement; it's named after
1476 the analogous function in Emacs.
1477 (scm_catch): Reimplemented in terms of the above.
1478 (struct catch_body_data, catch_body, catch_handler): New
1479 functions, used by scm_catch.
1480 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1481 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1482 support for new cwdr.
1484 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1487 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1489 * acconfig.h: Added DYNAMIC_LINKING symbol.
1490 * configure.in: Add option and checks for dynamic linking.
1491 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1492 dynl.h: New files for dynamic linking support.
1493 * Makefile.am (libguile_a_SOURCES):
1495 (modinclude_HEADERS): Added "dynl.h".
1496 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1498 * init.c (scm_boot_guile_1): Call
1499 scm_init_dynamic_linking to initialize dynamic linking support.
1501 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1503 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1504 (as we Schemers say). It needs to be global, so that I can tweak
1505 it for the proper operation of unexec.
1506 (scm_boot_guile_1_live): New variable, see above.
1508 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1510 * guile-snarf.sh: Removed.
1511 * PLUGIN/guile.libs: Added dependency for -lm.
1512 * acinclude.m4: Renamed from aclocal.m4.
1513 * PLUGIN/greet: Removed.
1514 * Makefile.am, aclocal.m4: New files.
1515 * configure.in: Updated for Automake.
1517 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1519 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1520 and not top_level_lookup_thunk_var.
1522 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1524 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1526 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1528 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1529 Scheme function, instead of syntax. Single argument is now a
1532 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1534 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1535 scm_ra_divide): Properly terminate statements passed as arguments
1536 to IVDEP macros. (Thanks to Bernard Urban.)
1538 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1539 with non-constant sizes. (Thanks to Bernard Urban.)
1541 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1543 It's an "eval closure", not an "eval thunk." A thunk is a
1544 function of no arguments.
1545 * root.h (struct scm_root_state): Renamed
1546 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1547 (scm_top_level_lookup_closure_var): Renamed from
1548 scm_top_level_lookup_thunk_var.
1549 * root.c (mark_root): Uses changed.
1550 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1551 * init.c (scm_start_stack): Uses changed.
1552 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1553 Change scheme-visible name to *top-level-lookup-closure* from
1554 *top-level-lookup-thunk*.
1556 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1558 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1559 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1561 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1563 * gc.c (struct scm_heap_seg_data): Doc fixes.
1565 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1566 sweeping. Then, prepend each segment's free cells to its
1567 freelist, rather than wiping out the old value. (Thanks to Marius
1570 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1571 scm_check_freelist, scm_debug_newcell): New functions and
1572 variables, for debugging freelist problems.
1573 * pairs.h (SCM_NEWCELL): New debugging version added.
1574 * gc.h (scm_debug_newcell): Added extern declaration, used by
1575 debugging version of SCM_NEWCELL.
1577 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1579 On some systems <libc.h> conflicts with <unistd.h>, and should not
1580 be #included at all.
1581 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1582 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1583 * configure.in: Call it.
1584 * posix.c, filesys.c: Use its results to decide whether or not to
1586 * configure, scmconfig.h.in: Rebuilt with autoconf and
1589 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1591 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1592 pointer to the stdio stream before calling scm_setbuf0, so the
1593 latter will be able to retrieve it. I'm surprised this didn't
1594 segfault earlier. (Thanks to Christopher Lee.)
1596 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1598 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1601 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1603 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1604 number of stack narrowing specifier pairs. The first specifier in
1605 a pair controls inner border, the second the outer border. A
1606 number means cut that number of frames, a procedure object means
1607 cut until that object is found in operator position in a frame.
1609 * root.c (cwdr): Bugfix.
1611 * read.c: Recording of positions disabled by default.
1613 * procs.c (scm_closure_p): New function.
1615 * posix.c (scm_tmpnam): New function.
1617 * load.c: Added #include "throw.h".
1618 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1621 * load.c, load.h (scm_read_and_eval_x): New function.
1623 * eval.c: Renamed debug option "deval" to "debug".
1625 (scm_eval_x): `eval!' is no longer accessible from the scheme
1626 level. Motivation: We can't allow operations which introduce
1627 glocs into the scheme level. Guile's type system can't handle
1628 these as data. Use `eval' or `read-and-eval!' as replacement.
1630 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1631 SCM_CONSP since this is a macro!; Set vframe.prev to
1632 scm_last_debug_frame instead of 0. In this way we can look
1633 "above" the virtual start stack frame if we wish.
1634 (scm_debug_hang): New function: Useful for debugging Guile in
1635 certain tricky situations. Will probably be removed later...
1637 * debug.h: Changed semantics of debug option "backtrace". This
1638 option now only indicates whether we want automatic backtrace at
1641 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1643 * ports.c: #include "filesys.h"
1644 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1646 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1647 Motivation: This is system specific code which is related to file
1648 I/O. It also may use select. Added code by Gary Houston to
1649 detect presence of character in stdio buffers.
1651 * libguile.h: #include "libguile/libpath.h"
1653 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1654 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1655 SCM_SITE_DIR; Install libpath.h among the other include files.
1657 * load.c, load.h (scm_sys_package_data_dir): New function.
1659 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1661 * stacks.h: Bugfix: Don't use tail-array length field as stack
1662 length field! This screwed GC.
1664 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1666 * _scm.h: Added #ifndef around definition of macros min and max.
1668 * __scm.h: Added hooks for threads to plugin to in ints protection
1669 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1670 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1671 the main code in these macros duplicated and spread over multiple
1672 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1673 SCM_THREAD_SWITCHING_CODE.
1675 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1677 * snarf.h: New file.
1678 * guile-snarf.sh: New file.
1679 * Makefile.in (inner_h_files): Added snarf.h
1680 (ancillary, install, uninstall, distclean): Added actions for
1682 (.c.x): Use guile-snarf.
1683 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1684 (gen_c_files): Note that these depend on guile-snarf.
1685 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1686 now in "snarf.h". Added #include "snarf.h" to get them.
1687 * libguile.h: Added #include "snarf.h".
1688 (Patches applied and tweaked by Jim Blandy.)
1690 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1692 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1693 standards suggest against providing prototypes for system
1694 functions. Thanks to Greg Troxel.
1696 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1698 * strports.c (scm_eval_0str): New function.
1699 #include "read.h", to get prototype for scm_read.
1700 * Makefile.in (strports.o): Update dependencies.
1701 * strports.h: New prototype.
1703 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1704 scheme name from "int?" to "integer?". It seems to do the job.
1705 * numbers.h: Rename prototype too.
1706 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1709 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1710 scm_num_eq_p): Rename these according to R4RS conventions: call
1711 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1712 to making libguile R4RS compliant without ice-9...
1714 * load.c (scm_sys_search_load_path): Search for files under all
1715 extensions listed in the %load-extensions variable. If FILENAME
1716 is absolute, return it unchanged, without searching the load path.
1717 (scm_loc_load_extensions): New variable, pointing to
1718 %load-extensions' value cell.
1719 (scm_init_load): Initialize it, and the value it points to.
1720 (scm_primitive_load_path): Improve error reporting.
1722 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1723 of new Scheme variable %load-hook.
1724 (scm_primitive_load): Apply %load-hook to filename.
1726 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1728 * configure.in: add tests for figuring out whether buffered data
1729 is available in a FILE structure, which is needed by char-ready.
1731 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1734 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1735 exceptions using misc_error instead of syserror. It seems a bit
1736 odd to throw an exception if a string can't be found in the
1737 environment, but it's consistent with open-file, stat etc.
1738 (simpos.h): remove sys_ from getenv.
1740 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1741 occurs, throw an error instead of returning errno. Return value
1743 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1745 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1747 * filesys.c (scm_stat2scm): derive file type and permissions from
1748 the stat mode and append them to the returned vector.
1749 There isn't much overhead in doing this and it avoids the need to
1750 work with S_IRUSR et al. in Scheme.
1751 Define symbols scm_sym_regular etc.
1752 (scm_init_filesys): don't intern S_IRUSR etc.
1754 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1755 and s_primitive_load_path.
1757 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1759 * error.h: don't declare error symbols. prototype for scm_misc_error.
1761 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1764 * error.c: use SCM_SYMBOL to set up error keys.
1765 scm_misc_error: new procedure.
1767 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1769 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1770 between `#!' and `!#' is ignored.
1771 (skip_scsh_block_comment): New function.
1773 * feature.c (scm_set_program_arguments): New argument, FIRST.
1774 * feature.h: Update prototype.
1775 * init.c (scm_boot_guile_1): Pass new argument to
1776 scm_set_program_arguments.
1778 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1780 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1781 (scm_boot_guile): Call scm_set_program_arguments here, later than
1782 the old initialization.
1784 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1785 initialization procedure.
1786 - Delete in, out, err arguments; there are other perfectly good
1787 ways to override these when desired.
1788 - Delete result argument; this function shouldn't ever return.
1789 - Rename init_func argument to main_func, for less confusion.
1790 - Delete boot_cmd argument; main_func is more general.
1791 -Add 'closure' argument, to help people pass data to main_func
1792 without resorting to global variables.
1793 - Abort if reentered; don't bother returning an error code.
1794 - Call scm_init_standard_ports to set up the default/current
1795 standard ports; no need to pass them to scm_start_stack.
1796 - Remove code to evaluate the boot_cmd, and start the repl; let
1797 the user do something like that in main_func if they want.
1798 - Remove code to package up a return value; main_func can do any
1800 - Call exit (0), instead of returning.
1801 (scm_start_stack): Don't initialize the I/O ports here; that's
1802 weird. Delete in, out, err arguments. Move guts to
1803 scm_init_standard_ports, scm_stdio_to_port.
1804 (scm_init_standard_ports): New function, to set up current and
1805 default standard ports.
1806 (scm_start_stack, scm_restart_stack): Make these static.
1807 * init.h (scm_boot_guile): Adjust declaration.
1808 (scm_start_stack, scm_restart_stack): Remove externally
1809 visible declarations for these.
1810 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1812 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1813 written out several times in scm_start_stack.
1814 * fports.h: New declaration for the above.
1816 * feature.c (scm_set_program_arguments): New function.
1817 * feature.h: New declaration for the above.
1819 * ports.c: Formatting tweak.
1821 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1823 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1824 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1825 for obtaining the address of a car or cdr field. Motivation:
1826 &SCM_CXR make assumptions about the internal structure of the
1829 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1830 Motivation: see SCM_CXRLOC.
1832 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1833 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1834 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1835 Motivation: Safer use. Some other macros are defined in terms of
1836 these operations. If these are defined using the SCM_SETCXR
1837 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1838 to inefficiency and an <e1> with side-effects could potentially
1839 break. Also, these particular operations are heavily utilized in
1840 the garbage collector. In unoptimized code there will be a
1843 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1844 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1845 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1846 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1847 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1848 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1849 vports.c: Cleaned up use of pairs: Don't make any special
1850 assumptions about the internal structure of selectors and
1851 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1852 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1853 (Among other things, this change makes it easier to build Guile
1854 with certain compilers which have problems with casted lvalues.)
1856 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1858 * stacks.c: Improve selection of relevant stack frames when making
1859 a stack object. Introduce one level of indirection in the stack
1860 object to make it possible to "narrow" to a certain region of the
1861 stack. This facilitates making use of more clever algorithms (not
1862 implemented) for selecting relevant frames and gives a cleaner
1863 design since selection of frames can be done independently of
1864 extraction of frames from the real stack.
1865 (scm_stack_id): Also take #t as argument which means look at
1868 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1869 Turn n_tail into an integer directly representing current number
1870 of frames in stack. Add field tail.
1872 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1874 * debug.c (scm_make_memoized): Made it available at scheme level.
1875 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1876 SCM_NIMP before applying heavier predicates in argument checking.
1877 (scm_local_eval): Also take memoized object as argument.
1879 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1880 aren't created with zero length, but should such a strange
1881 creature suddenly turn up...
1883 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1885 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1886 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1888 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1890 * variable.c (scm_make_variable): Make the name hint optional, as
1892 (anonymous_variable_sym): Renamed from variable_sym. All uses
1895 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1896 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1897 of scm_primitive_load_path was also changed to
1898 "primitive-load-path", from "%try-load-path". Callers changed.
1899 We'd like to respect the convention that a function named
1900 "try-mumble" should behave just like the function called "mumble",
1901 but return #f instead of signalling some error.
1902 * load.h: Rename prototypes.
1904 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1906 * print.c (make_print_state, grow_print_state), print.h: Modified
1907 the print state representation: Don't use a tail array for
1908 recording of circular references. Resizing of the print state
1909 structure invalidates the print state pointer. To avoid passing
1910 around an indirect print state reference to all printing
1911 functions, we instead let the print state reference a resizable
1914 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1916 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1917 Don't crash when passed an improper list terminated by a
1918 non-immediate value.
1920 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1922 Allocate data for structures on an eight-byte boundary, as
1923 required by the tagging system.
1924 * struct.c (alloc_struct): New function.
1925 (scm_make_struct, scm_make_vtable_vtable): Call it.
1926 * struct.h (scm_struct_n_extra_words): Bump to 3.
1927 (scm_struct_i_ptr): New "field".
1928 * gc.c (scm_gc_sweep): When we need to free the data, use the
1929 information stored by alloc_struct to find the beginning of the
1930 block allocated to the structure, so we can free it.
1932 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1934 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1937 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1938 (scm_debug_info): New member: id.
1940 * stacks.c: Stacks are now represented as structs; Stacks have an
1941 id given to them by `start-stack'.
1942 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1944 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1945 Changed stack representation.
1947 * debug.c (scm_procedure_name): Try procedure property `name' for
1948 compiled closures aswell.

1954 objects. (Earlier, only closures were recorded.)
1956 * procprop.h: Added declaration of scm_i_name.
1958 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1959 (scm_make_gsubr): Record names of compiled closures.
1961 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1963 * debug.c, debug.h: Removed obsolete code.
1965 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1966 stacks.c: Renamed regs --> scm_contregs.
1968 * print.c (scm_free_print_state): Cleanup print state before
1969 returning it to pool. It is better to do it here than in
1970 scm_prin1 since scm_prin1 is called often.
1972 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1973 s_set_source_property_x): Check that first argument is a pair or a
1976 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1977 scm_i_line, scm_i_column and scm_i_breakpoint global.
1979 * init.c: Added #include "backtrace.h" and #include "stacks.h".

1990 backtrace.h, stacks.c and stacks.h.
1992 * symbols.c (scm_sym2ovcell): Fixed documentation.
1994 * _scm.h (min, max): Added.
1996 * async.c: Moved `min' macro to _scm.h.
1998 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1999 SCM_BACKTRACE_INDENT.
2001 * eval.c: Added new debug options `maxdepth' and `indent'.

2010 * print.h: Added declarations for scm_make_print_state,
2011 scm_free_print_state.
2013 * debug.c (scm_m_start_stack): New acro.
2015 * debug.h: Small cleanup.
2017 * init.c (scm_boot_guile_1): Moved scm_init_debug below

2040 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
2041 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
2042 declare functions with prototypes. (Patch thanks to Marius
2045 More prototype-related changes from Marius Vollmer:
2046 * gdb_interface.h: Wrapped header file in #ifdef/#endif
2047 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
2048 * ports.h (ptobfuns): Added prototypes. This means some casting in
2050 * fports.c: Added casts for initializations, since the functions
2051 are defined to take FILE * as their stream argument, not SCM.
2052 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
2053 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
2054 to `char *str_data' to conform to prototype.
2056 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2058 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
2060 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
2062 * stime.c, stime.h: use SCM_P method.
2064 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2066 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
2067 be given at least two arguments. Insist that lst's last element
2068 be a list, but don't make any requirements of its predecessors.
2070 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2072 * eval.c (scm_nconc2last): Revert last change; there seems to be
2073 other stuff going on here.
2075 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2077 * eval.c (scm_nconc2last): Make sure that each element of lst
2078 (which is a list of argument lists, except for the tail) is a
2079 proper list, i.e., finite and terminated by '().
2081 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2083 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
2086 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
2087 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
2090 * vectors.c (scm_make_vector): Fill vectors with the undefined
2091 value, to help make Guile Scheme code more portable to other
2094 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
2095 * symbols.h, tags.h: Doc fixes.
2097 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
2099 * async.c (scm_take_signal): Doc fixes.
2101 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
2103 * numbers.c (scm_divbigint): When the remainder is zero, we don't
2104 want to subtract it from the modulus; we just want to leave it
2107 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
2109 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
2112 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
2114 * throw.c (scm_catch_apply): Finished implementation of
2117 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2119 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn

2124 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
2126 * Makefile.in (root.o): Correct dependencies.
2128 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
2130 * Makefile.in: Added dependency entry for root.o.
2132 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
2133 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
2135 * init.c (scm_start_stack): Set initial root continuation number
2138 * procs.c: New function: scm_thunk_p.
2140 * procs.h: Added declarations of scm_thunk_p.
2142 * root.c: Renamed `call-with-new-root' -->
2143 `call-with-dynamic-root'.
2144 (cwdr): Removed allocation of new root state. This should be done
2145 separately by use of scm_make_root.
2146 (scm_apply_with_dynamic_root): New function: Does what it
2147 sounds like. Needed when spawning threads.
2149 * root.h: Added member last_debug_frame to root state.
2150 Added #include "libguile/debug.h"
2152 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
2153 arguments. The motivation is that code in root.c needs catch
2154 functionality, and we want to avoid code duplication.
2155 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2156 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2157 handlers that run without popping the stack into the dynwind
2160 * throw.h: Added prototypes for scm_catch_apply and
2163 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2165 * root.h (scm_root, scm_set_root): Decouple thread support details
2166 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2167 SCM_SET_THREAD_LOCAL_DATA.
2169 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2170 and tortoise scanning loop.
2172 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2174 * Makefile.in: Rebuild dependencies.
2176 * libguile.h: #include "libguile/print.h" before "smob.h", since
2177 the latter uses the print_state structure.
2179 * throw.c (scm_ithrow): Use the correct variable when checking to
2180 see if a given element of scm_dynwinds is a valid catch.
2182 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2183 structure, abort; don't just silently ignore the garbage.
2185 * _scm.h: #include "print.h" here, since it seems to be used just
2187 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2188 strports.c, unif.h: Don't #include "print.h".
2190 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2192 * feature.h (scm_loc_features): Removed external declaration.
2193 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2195 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2197 * feature.c (scm_init_feature): Added threads feature (needs to be
2198 initialized here, since features doesn't exist when
2199 scm_init_threads is called).
2201 * libguile.h: Added #include "libguile/../threads/threads.h".
2202 (This is a kludge to get thread support working. This should be
2205 * configure.in, acconfig.h: Added flags for thread support.
2207 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2210 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2211 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2214 * _scm.h: Added conditional #include "threads.h"
2216 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2217 SCM_THREADS_SWITCHING_CODE.
2219 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2220 allocate the basic dynamic root object.
2221 (scm_boot_guile): Added call to scm_init_root.
2223 * root.c, root.h: Added root smob.
2224 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2225 functions: Implements dynamic roots mostly according to spec in
2226 SCM manual. Main difference is that the second argument is a
2227 throw handler rather than an error "thunk".
2229 * root.h: Added declaration of scm_init_root.
2231 * root.c: Added #include "genio.h", #include "smob.h", #include
2232 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2234 (scm_init_root): Added #include "root.x".
2236 * throw.c: Added #include "stackchk.h"
2237 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2238 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2239 can be used in scm_call_with_new_root; Added reenabling of stack
2240 checking when catching a throw.
2242 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2244 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2246 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2247 element is not found, as per R4RS.
2249 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2251 * list.c: Doc fixes throughout.
2253 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2255 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2256 declare the char * to be const. Avoids a warning in rgx.c.
2258 * ports.h: spelling fix.
2260 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2263 * load.c (scm_sys_try_load_path): throw an error if file not found
2264 (like it says it in NEWS).
2266 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2268 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2269 PROPS slot to '(), not #f; it's an empty alist.
2271 * throw.h, throw.c: Use SCM_P instead of #if hair.
2273 Remove special support for uncaught throws; see throw.c for
2275 * throw.c (uncaught_throw): New function.
2276 (scm_ithrow): Call uncaught_throw if we don't find a throw
2277 target; don't mess with scm_bad_throw_vcell.
2278 (scm_bad_throw_vcell): Variable deleted.
2279 (scm_init_throw): Don't initialize it.
2281 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2284 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2286 * numbers.c (scm_istr2int): If the number is short (as most
2287 numbers are), just call scm_small_istr2int to deal with it.
2288 (scm_small_istr2int): New function, created by un-#ifdefing the
2289 non-bignum version of scm_istr2int and renaming it.
2291 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2293 * load.c (scm_sys_try_load): don't check whether value returned
2294 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2295 Change the Scheme name from %try-load to primitive-load.
2297 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2298 Can avoid passing a message, allowing it to be derived in the
2299 error handler (e.g., if we want to throw to the key both from
2302 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2304 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2305 references now have a new appearance which is more compact and
2306 also gives a clue about what the target of the reference is.
2307 By setting parameters in the print state, more fancy printing can
2308 be achieved. This is used by the (not yet commited) backtrace
2311 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2313 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2316 * print.c: Added #include "struct.h". Removed function
2319 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2320 scm_iprin1. Removed prototype for scm_prlist.
2322 * arbiters.c (prinarb),
2323 async.c (print_async),
2324 debug.c (prindebugobj, prinmemoized),
2325 eval.c (prinprom, prinmacro),
2326 filesys.c (scm_fd_print, scm_dir_print),
2328 mallocs.c (prinmalloc),
2329 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2330 smob.h (scm_smobfuns),
2331 srcprop.c (prinsrcprops),
2333 unif.c, unif.h (scm_raprin1, rapr1),
2334 variable.c (prin_var): Changed argument `int writing' to
2335 `scm_print_state *pstate'.
2337 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2338 that it will be called before scm_init_print.
2340 * print.c (scm_prin1): Print states are now allocated when calling
2341 scm_prin1 and then passed around to all printing functions as an
2342 argument. A cache `print_state_pool' enables reuse of print
2344 (scm_make_print_state): New function.
2345 (scm_iprin1): Adaption to print states.
2346 (scm_iprlist): An initial "hare and tortoise" scan brings down
2347 time complexity to O (depth * N). (Better time complexity will be
2348 achieved when the printing code is completely rewritten.)
2350 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2352 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
2353 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
2354 it gets done whether or not the cache variable has a value.
2356 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2358 Distinguish #f and ().
2359 * __scm.h: #undef SICP.
2360 * pairs.h (SCM_EOL): Delete this definition, equating it with
2362 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2363 the value it used to have. Doc fixes, too.
2365 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2367 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2368 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2369 Lord's implementation of structs, allowing for tail arrays as
2370 described in the manual. Also fixed some bugs. (Both the interface
2371 and the implementation should be improved.)
2373 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2375 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2376 People who whish to see the source can do `(print-enable 'source)'.
2377 Removed #ifdef DEBUG_EXTENSIONS.
2379 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2381 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2382 integer (assuming for now accepting an integer is a good thing).
2384 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2385 %S will be used instead for write'ing arguments.
2387 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2388 asserts. fix a few other asserts.
2389 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2390 scm_uniform_vector_ref, scm_array_set_x,
2391 scm_dimensions_to_unform_array): change args in
2392 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2393 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2394 scm_substring_fill_x): likewise.
2395 gsubr.c (scm_gsubr_apply): likewise.
2396 eval.c (SCM_APPLY): likewise.
2398 * eval.c (4 places): replace scm_everr with lgh_error or
2401 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2402 scm_memory_error): new procedures.
2403 scm_everr: deleted. can use scm_wta, dropping first two args.
2404 scm_error: convert NULL subr to SCM_BOOL_F.
2406 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2409 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2412 * error.c, error.h: new error keys: scm_arg_type_key,
2413 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2415 scm_wta: reimplement using lgh_error instead of scm_everr.
2417 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2419 * gdbint.c: scm_lread now has one more argument.
2421 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2422 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2423 loading source from non-file ports, which, e. g., happens when
2424 using the Emacs interface).
2426 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2429 * read.c: Added code for recording of positions of source code
2430 expressions; New functions: recsexpr, scm_lreadrecparen;
2431 _scm_make_srcprops --> scm_make_srcprops
2432 (scm_flush_ws): Removed updating of positions counters. This work
2433 is already done by scm_gen_getc
2435 * read.h: Added prototype for scm_lreadrecparen
2437 * print.c: Added #include "alist.h"
2439 * eval.c: Added #include "hash.h"
2441 * eq.c: Added #include "ramap.h"
2443 * options.c: Documentation fixes.
2445 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
2446 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2447 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2448 --> scm_make_srcprops
2450 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2451 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2452 function calls in the definition of the whash access macros.
2454 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2456 * init.c (scm_boot_guile): Add level of indirection to
2457 scm_boot_guile_1() to ensure that stack base pointer is properly
2458 initialized. There was no guarantee that variable i was the
2459 highest/lowest variable on stack (i.e. the call frame of
2460 scm_boot_guile was not completely protected from gc).
2462 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2464 * ports.h (scm_port_table): put back file_name, it will be used to
2465 support debugging. Undo related changes in fports.c, ioext.c,
2468 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2470 * ports.h (scm_port_table): remove file_name member for now, it seems
2472 * fports.c (scm_open_file): don't set file_name in PTAB.
2473 (prinfport): don't use file_name in PTAB.
2474 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2475 * ports.c (scm_add_to_port_table): don't intialize file_name.
2476 (scm_port_file_name): remove for now.
2477 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2479 * fports.h (scm_mkfile): prototype deleted.
2480 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2482 * debug.c, unif.c: use scm_out_of_range instead of
2483 wta for range errors (ASSERT still needs work).
2485 * error.c, error.h (scm_out_of_range): new procedure.
2487 * error.c, error.h (scm_out_of_range_key): new key.
2489 * posix.c (scm_sync): #else was missing.
2491 * error.c, error.h: append _key to names scm_num_overflow and
2494 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2495 of consing an empty list.
2496 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2497 of macros, saves code and string space.
2498 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2499 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2500 lower case. Rename scm_syserror_m to scm_syserror_msg.
2501 error.h: prototypes for new procedures.
2503 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2505 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2507 * error.c, error.h: setup scm_num_overflow key.
2509 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2510 Remove definition of SCM_OVSCM_FLOW.
2512 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2514 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2515 explicit message and args.
2517 * error.c, error.h, __scm.h: change system_error_sym to
2520 * error.c (system_error_sym): remove leading %% from the Scheme name
2523 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2525 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2527 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2528 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2529 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2530 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2531 renamed. (These were introduced by unsupervised name
2534 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2536 * print.c: Added code for detection of circular references during
2537 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2538 a hook for printing of closures (accessible via print options).
2539 This leads to a split of calls to scm_iprin1 into two classes:
2540 elementary print operations (e. g. the code which prints a smob)
2541 still use scm_iprin1 while top level calls (like scm_display) use
2542 scm_prin1. scm_prin1 begins by clearing the data structure used
2543 to record reference information.
2545 * print.h: Added declarations of scm_prin1 and scm_prlist.
2547 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2549 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2551 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2553 * error.c (err_head): scm_iprin1 --> scm_prin1
2555 * debug.c: Adjusted header comment.
2559 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2561 * strerror.c: Doc fix.
2563 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2565 * gdbint.c (gdb_read): Now possible to run during GC.
2566 (unmark_port, remark_port): New functions.
2568 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2570 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2571 of allocating a new string object. Also, increase size by
2572 the factor 2 instead of 1.5.
2574 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2576 * __scm.h (SCM_P): Corrected to run under traditional C.
2578 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2581 * async.c: Calls to scm_sysintern corrected.
2583 * async.h (scm_async_clock): Redundant declaration removed.
2585 * continuations.c (scm_dynthrow): Redundant declaration removed.
2587 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2588 Definition typos corrected.
2590 * debug.h: Missing declarations of functions in debug.c added
2593 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2594 Missing declarations to functions in eval.c added.
2596 * filesys.c: Possibly uninitialized variable rv.
2598 * gc.h (scm_object_addr, scm_unhash_name): Missing
2599 declarations of functions defined in gc.c added.
2601 * genio.c: Possible typos str_data -> wstr_data. ???
2603 * genio.c: Possibly unintended shadowing of local variable
2604 `int c' (gotos out of scope of inner `c'). ???
2606 * init.c: Uninitialized `SCM last' may be used.
2608 * ioext.h: (scm_sys_isatty_p): Typo.
2610 * list.h (scm_list_head): Missing prototype for function in
2613 * numbers.c (scm_two_doubles): Changed from extern to static
2614 (is used only within numbers.c).
2616 * numbers.h: Repeated declarations removed.
2618 * ports.h (scm_close_all_ports_except): Declaration for the
2619 function defined in ports.c added.
2621 * posix.h: Missing declarations added.
2623 * procs.h (scm_make_subr_opt): Missing declaration added.
2625 * socket.h (scm_sys_gethost): Missing declaration added.
2627 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2629 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2630 Missing declarations added.
2632 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2634 * struct.c: Uninitialized variable `SCM answer' may be used.
2636 * unif.c (l2ra): Declaration prototype.
2638 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2639 defined in ramap.c).
2641 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2642 Redundant declarations removed (they are in ramap.h).
2644 * variable.h (scm_make_udvariable,
2645 scm_make_undefined_variable): Declaration corrected to
2646 correspond variable.c.
2648 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2649 Missing declarations added.
2651 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2653 * Makefile.in (distclean): Don't forget to delete fd.h.
2655 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2657 * fd.h.in, tags.h: Trivial cleanups.
2659 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2660 marksweep.h just declared functions from gc.c.
2661 * gc.h, libguile.h: Don't #include "marksweep.h".
2662 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2663 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2664 dependencies updated.
2666 * libguile.h: Don't #include "files.h"; it's been deleted.
2668 * files.c (scm_sys_delete_file): Moved to filesys.c.
2669 File is now empty; deleted.
2671 * filesys.c: scm_sys_delete_file is now here. Remove
2672 #if's; they seem to rely on remnants of an old portability
2673 regimen. If the problems come up again, solve them properly,
2674 using autoconf. Specifically: Don't test M_SYSV, and #define
2675 remove to be unlink if it's #defined; don't use remove just
2676 because HAVE_STDC_HEADERS is #defined.
2677 * filesys.h: Add declarations for scm_sys_delete_file.
2678 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2679 files.o, files.h, files.c, and files.x.
2680 * init.c: Don't #include "files.h", and don't call scm_init_files.
2682 Use SCM_P instead of PROTO; the latter intrudes on the user's
2684 * params.h: Deleted; definition of SCM_P moved to...
2685 * __scm.h: ... here, where it replaces PROTO macro.
2686 * libguile.h, smob.h: Don't #include "params.h".
2687 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2688 smob.h: Fix prototypes accordingly.
2689 * Makefile.in: Update dependencies.
2690 (inner_h_files): Remove params.h.
2692 * gc.c: #include "gc.h"; every module should include its header,
2693 to let the compiler cross-check the declarations against the
2696 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2697 simpos.h: #include "libguile/__scm.h".
2699 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2701 * init.c: Don't forget to #include smob.h and init.h.
2702 * Makefile.in: Dependencies updated.
2704 * smob.h: Use PROTO instead of #if __STDC__.
2706 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2708 * __scm.h: Doc fixes.
2710 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2711 <angles>; this allows `make depends' to work properly.
2713 * libguile.h: #include smob.h and pairs.h before the others; they
2714 define typedefs used by other headers.
2716 C files should #include only the header files they need, not
2717 libguile.h (which #includes all the header files); the pointless
2718 recompilation was wasting my time.
2719 * Makefile.in (all .o dependency lists): Regenerated.
2720 * libguile.h: Don't try to get a definition for size_t here...
2721 * __scm.h: Do it here.
2722 * _scm.h: Since this is the internal libguile header, put things
2723 here that all (or a majority) of the libguile files will want.
2724 Don't #include <libguile.h> here; that generates dependencies on
2725 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2726 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2727 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

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

3405 (installed_h_files): Put in alphabetical order.
3406 Remove duplicate entries for markers.h and unif.h.

3408 (ancillary): Renamed from anillery; all uses changed. Remove
3409 PLUGIN; it's a directory, and needs special treatment in dist-dir.

3412 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3414 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3415 every if must have an else, or else the whole command has a
3416 non-zero exit code whenever the if's condition is false.

3483 matter so long as it is non-0 (got rid of "* 4").
3485 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3487 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3488 since its definition was bogus).

3494 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3496 * ports.c: removed functions relating to the mapping between ports
3497 and descriptors. (That stuff is unix-specific and should be collected

3505 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3506 handled correctly (SCM_FREEP was applied to them) -- test for
3507 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

3675 initialization to fix a race condition.
3677 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

3701 set the multi_byte flag correctly in symbols. This is wrong.
3702 intern_obbary_soft and msymbolize should take an extra parameter.

3704 The weird symbol syntax is also a bit bogus (emacs doesn't quite
