4 (scm_pipob): Use it in the initializer here.
7 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
8 Use a meaningful error message when signalling an error. For
9 this, scm_gethost must check h_errno rather than errno.
11 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
13 * Makefile.in: Regenerated, using automake-1.1p.

17 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
20 * script.c (scm_compile_shell_switches): don't append (quit) if
22 (scm_shell): call scm_exit_status and exit on the result of the
25 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
27 Ensure that shared substrings are handled properly when passed to
28 a system call or other foreign function. Many thanks to Tim
30 * symbols.h (SCM_COERCE_SUBSTR): new macro.
31 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
32 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
33 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
34 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
35 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
36 (scm_display_error_message): use RO macros when strings may be RO.
37 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
38 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
39 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

42 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
43 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
44 scm_strftime), vports.c (scm_make_soft_port): use
45 SCM_COERCE_SUBSTR to make sure shared substrings are

54 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
56 * dynl-shl.c: Completely replaced with new code from Bernard
59 * script.c (scm_ice_9_already_loaded): New variable.
60 (scm_compile_shell_switches): Use it.
62 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
64 * filesys.c (scm_input_waiting_p): add missing third argument to

76 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
78 * Makefile.am (check-local): New target, which causes 'make check'
79 to run gh_test_c and gh_test_repl, with some trivial input.
80 * Makefile.in: Rgnrtd.
82 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
84 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
87 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
89 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
90 sure how this was supposed to work.
91 (scm_async_click): don't send SCM_TICK_SIGNAL.
92 (scm_init_async): don't initialize %tick-thunk.
94 * the following change doesn't affect the Scheme interface:
95 gc-thunk is called at the end of garbage collection. however it's
96 no longer implemented by pretending it's a signal.
98 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
99 system async corresponding to scm_gc_thunk.
100 * async.h: declare scm_gc_async.
101 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
102 gc-thunk directly, instead of going through a signal handler.
103 (scm_gc_async): new variable, points to the GC system-async.
104 (scm_init_async): save the GC async as scm_gc_async instead
105 of using system_signal_asyncs.
106 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
108 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
110 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
111 Don't screw up if we're interrupted.
112 * Makefile.in: Regeneradet.
114 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
116 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
118 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
119 we're not using AM_INIT_GUILE_MODULE any more.
120 * Makefile.in: Reneregated.
122 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
124 Functions for finding variable bindings, grace à Tim Pierce.
125 * * gh_data.c (gh_lookup, gh_module_lookup): New functions.
126 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
128 Get 'make dist' to work again.
129 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
130 * Makefile.in: Regenerated, like a surry without a fringe on top.
132 Changes for reduced Guile distribution: one configure script,
134 * configure.in, configure: Removed.
135 * acconfig.h, acinclude.m4: Moved to parent directory, where the
136 real configure script lives.
137 * Makefile.in, scmconfig.h.in: Regenerated.
139 * init.c: #include "script.h", to get prototype for script.c's
142 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
144 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
145 scm_must_malloc, not raw malloc.
147 * script.c (scm_compile_shell_switches): Dyke out debugging output
150 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
152 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
154 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
155 system has them. Hope this is safe. Previously
156 sys/timeb.h was included if HAVE_FTIME was defined or if
157 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
158 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
160 * ioext.c (scm_setfileno): add missing third argument to
163 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
165 * eq.c (scm_equal_p): Correctly compare strings of different
166 varieties. (Thanks to Tim Pierce.)
168 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
170 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
171 #! block comment must occur on a line all by itself.
173 Move most of the guts of shell command processing into libguile,
174 so guile.c can be very small (and eventuallly auto-generated. (I
175 mean, generated mechanically, not self-generated. Hmm.))
176 * guile.c, script.c, script.h: New source files.
177 * init.c (scm_boot_guile_1): Call scm_init_script.
178 * libguile.h: #include "script.h".
179 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
180 targets, for new executable.
181 (libguile_la_SOURCES): Mention script.c.
182 (modinclude_HEADERS): Add script.h.
183 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
184 not dynamic linking is enabled. This is because we're generating
185 executables now. Move CY_AC_WITH_THREADS call after those, so the
186 values of cy_cv_threads_libs captures the libs chosen above.
187 * Makefile.in, configure, aclocal.m4: Regenerated.
189 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
190 We don't maintain this interface any more, and it just confuses
193 * alloca.c: #include <scmconfig.h>, not <config.h>.
194 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
195 it'll get included in disties.
197 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
199 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
200 be distributed, because they confuse people.
201 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
203 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
205 * configure.in: check for presence of gethostent (not present on
207 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
208 * configure, scmconfig.h.in: Regenerated.
210 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
212 * backtrace.c (scm_backtrace): Split message string across
213 newlines properly. GCC is more tolerant of this than other
216 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
218 Merge threads directory into libguile.
219 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,

224 (modinclude_HEADERS): Add threads.h, coop-defs.h.
225 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
226 coop-threads.c.cygnus, coop-threads.h.cygnus.
227 * configure.in: If we're using threads, include threads.o in
229 * _scm.h, libguile.h: threads.h lives in this directory now.
230 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
231 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
232 currently used, but brought along for information's sake.
233 * ChangeLog-threads: log from old 'threads' directory.
234 * Makefile.in, configure: Rebuilt.
236 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
238 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
241 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
243 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
245 Merge GH interface library into libguile.
246 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
247 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
248 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
249 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
251 (EXTRA_libguile_la_SOURCES): ... here.
252 (pkginclude_HEADERS): Add variable, to get gh.h installed.
253 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
254 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
255 New variables, describing how to build the gh test programs.
256 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
257 build the test programs, and we probably should have been linking
258 libguile.la against them all along, to support AIX shared libs.
259 Add cflags for threads to CFLAGS; add libs for threads to new
260 variable THREAD_LIBS, used in Makefile.am.
261 * ChangeLog-gh: log from old `gh' subdirectory.
262 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
264 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
266 * acconfig.h: Undo change of Apr 9; including the definition of
267 PACKAGE in the guile headers conflicts with applications' own
269 * scmconfig.h.in: Regenerated.
271 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

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

1947 backtrace.h, stacks.c and stacks.h.
1949 * symbols.c (scm_sym2ovcell): Fixed documentation.
1951 * _scm.h (min, max): Added.
1953 * async.c: Moved `min' macro to _scm.h.
1955 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1956 SCM_BACKTRACE_INDENT.

1962 * print.h: Added selector SCM_PRINT_STATE.
1964 * print.c: New functions: scm_make_print_state,
1965 scm_free_print_state.
1967 * print.h: Added declarations for scm_make_print_state,
1968 scm_free_print_state.
1970 * debug.c (scm_m_start_stack): New acro.
1972 * debug.h: Small cleanup.
1974 * init.c (scm_boot_guile_1): Moved scm_init_debug below

1998 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
1999 declare functions with prototypes. (Patch thanks to Marius
2002 More prototype-related changes from Marius Vollmer:
2003 * gdb_interface.h: Wrapped header file in #ifdef/#endif
2004 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
2005 * ports.h (ptobfuns): Added prototypes. This means some casting in
2007 * fports.c: Added casts for initializations, since the functions
2008 are defined to take FILE * as their stream argument, not SCM.
2009 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
2010 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
2011 to `char *str_data' to conform to prototype.
2013 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2015 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
2017 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
2019 * stime.c, stime.h: use SCM_P method.
2021 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2023 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
2024 be given at least two arguments. Insist that lst's last element
2025 be a list, but don't make any requirements of its predecessors.
2027 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2029 * eval.c (scm_nconc2last): Revert last change; there seems to be
2030 other stuff going on here.
2032 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2034 * eval.c (scm_nconc2last): Make sure that each element of lst
2035 (which is a list of argument lists, except for the tail) is a
2036 proper list, i.e., finite and terminated by '().
2038 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2040 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
2043 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
2044 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
2047 * vectors.c (scm_make_vector): Fill vectors with the undefined
2048 value, to help make Guile Scheme code more portable to other
2051 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
2052 * symbols.h, tags.h: Doc fixes.
2054 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
2056 * async.c (scm_take_signal): Doc fixes.
2058 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
2060 * numbers.c (scm_divbigint): When the remainder is zero, we don't
2061 want to subtract it from the modulus; we just want to leave it
2064 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
2066 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
2069 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
2071 * throw.c (scm_catch_apply): Finished implementation of
2074 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2076 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
2078 (scm_init_filesys): set "i/o-extensions" feature.
2081 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
2083 * Makefile.in (root.o): Correct dependencies.
2085 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
2087 * Makefile.in: Added dependency entry for root.o.
2089 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
2090 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
2092 * init.c (scm_start_stack): Set initial root continuation number
2095 * procs.c: New function: scm_thunk_p.
2097 * procs.h: Added declarations of scm_thunk_p.
2099 * root.c: Renamed `call-with-new-root' -->
2100 `call-with-dynamic-root'.
2101 (cwdr): Removed allocation of new root state. This should be done
2102 separately by use of scm_make_root.
2103 (scm_apply_with_dynamic_root): New function: Does what it
2104 sounds like. Needed when spawning threads.
2106 * root.h: Added member last_debug_frame to root state.
2107 Added #include "libguile/debug.h"
2109 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
2110 arguments. The motivation is that code in root.c needs catch
2111 functionality, and we want to avoid code duplication.
2112 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2113 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2114 handlers that run without popping the stack into the dynwind
2117 * throw.h: Added prototypes for scm_catch_apply and
2120 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2122 * root.h (scm_root, scm_set_root): Decouple thread support details
2123 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2124 SCM_SET_THREAD_LOCAL_DATA.
2126 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2127 and tortoise scanning loop.
2129 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2131 * Makefile.in: Rebuild dependencies.
2133 * libguile.h: #include "libguile/print.h" before "smob.h", since
2134 the latter uses the print_state structure.
2136 * throw.c (scm_ithrow): Use the correct variable when checking to
2137 see if a given element of scm_dynwinds is a valid catch.
2139 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2140 structure, abort; don't just silently ignore the garbage.
2142 * _scm.h: #include "print.h" here, since it seems to be used just
2144 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2145 strports.c, unif.h: Don't #include "print.h".
2147 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2149 * feature.h (scm_loc_features): Removed external declaration.
2150 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2152 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2154 * feature.c (scm_init_feature): Added threads feature (needs to be
2155 initialized here, since features doesn't exist when
2156 scm_init_threads is called).
2158 * libguile.h: Added #include "libguile/../threads/threads.h".
2159 (This is a kludge to get thread support working. This should be
2162 * configure.in, acconfig.h: Added flags for thread support.
2164 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2167 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2168 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2171 * _scm.h: Added conditional #include "threads.h"
2173 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2174 SCM_THREADS_SWITCHING_CODE.
2176 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2177 allocate the basic dynamic root object.
2178 (scm_boot_guile): Added call to scm_init_root.
2180 * root.c, root.h: Added root smob.
2181 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2182 functions: Implements dynamic roots mostly according to spec in
2183 SCM manual. Main difference is that the second argument is a
2184 throw handler rather than an error "thunk".
2186 * root.h: Added declaration of scm_init_root.
2188 * root.c: Added #include "genio.h", #include "smob.h", #include
2189 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2191 (scm_init_root): Added #include "root.x".
2193 * throw.c: Added #include "stackchk.h"
2194 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2195 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2196 can be used in scm_call_with_new_root; Added reenabling of stack
2197 checking when catching a throw.
2199 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2201 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2203 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2204 element is not found, as per R4RS.
2206 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2208 * list.c: Doc fixes throughout.
2210 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2212 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2213 declare the char * to be const. Avoids a warning in rgx.c.
2215 * ports.h: spelling fix.
2217 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2220 * load.c (scm_sys_try_load_path): throw an error if file not found
2221 (like it says it in NEWS).
2223 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2225 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2226 PROPS slot to '(), not #f; it's an empty alist.
2228 * throw.h, throw.c: Use SCM_P instead of #if hair.
2230 Remove special support for uncaught throws; see throw.c for
2232 * throw.c (uncaught_throw): New function.
2233 (scm_ithrow): Call uncaught_throw if we don't find a throw
2234 target; don't mess with scm_bad_throw_vcell.
2235 (scm_bad_throw_vcell): Variable deleted.
2236 (scm_init_throw): Don't initialize it.
2238 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2241 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2243 * numbers.c (scm_istr2int): If the number is short (as most
2244 numbers are), just call scm_small_istr2int to deal with it.
2245 (scm_small_istr2int): New function, created by un-#ifdefing the
2246 non-bignum version of scm_istr2int and renaming it.
2248 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2250 * load.c (scm_sys_try_load): don't check whether value returned
2251 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2252 Change the Scheme name from %try-load to primitive-load.
2254 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2255 Can avoid passing a message, allowing it to be derived in the
2256 error handler (e.g., if we want to throw to the key both from
2259 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2261 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2262 references now have a new appearance which is more compact and
2263 also gives a clue about what the target of the reference is.
2264 By setting parameters in the print state, more fancy printing can
2265 be achieved. This is used by the (not yet commited) backtrace
2268 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2270 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2273 * print.c: Added #include "struct.h". Removed function
2276 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2277 scm_iprin1. Removed prototype for scm_prlist.
2279 * arbiters.c (prinarb),
2280 async.c (print_async),
2281 debug.c (prindebugobj, prinmemoized),
2282 eval.c (prinprom, prinmacro),
2283 filesys.c (scm_fd_print, scm_dir_print),
2285 mallocs.c (prinmalloc),
2286 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2287 smob.h (scm_smobfuns),
2288 srcprop.c (prinsrcprops),
2290 unif.c, unif.h (scm_raprin1, rapr1),
2291 variable.c (prin_var): Changed argument `int writing' to
2292 `scm_print_state *pstate'.
2294 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2295 that it will be called before scm_init_print.
2297 * print.c (scm_prin1): Print states are now allocated when calling
2298 scm_prin1 and then passed around to all printing functions as an
2299 argument. A cache `print_state_pool' enables reuse of print
2301 (scm_make_print_state): New function.
2302 (scm_iprin1): Adaption to print states.
2303 (scm_iprlist): An initial "hare and tortoise" scan brings down
2304 time complexity to O (depth * N). (Better time complexity will be
2305 achieved when the printing code is completely rewritten.)
2307 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2309 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
2310 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
2311 it gets done whether or not the cache variable has a value.
2313 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2315 Distinguish #f and ().
2316 * __scm.h: #undef SICP.
2317 * pairs.h (SCM_EOL): Delete this definition, equating it with
2319 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2320 the value it used to have. Doc fixes, too.
2322 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2324 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2325 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2326 Lord's implementation of structs, allowing for tail arrays as
2327 described in the manual. Also fixed some bugs. (Both the interface
2328 and the implementation should be improved.)
2330 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2332 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2333 People who whish to see the source can do `(print-enable 'source)'.
2334 Removed #ifdef DEBUG_EXTENSIONS.
2336 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2338 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2339 integer (assuming for now accepting an integer is a good thing).
2341 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2342 %S will be used instead for write'ing arguments.
2344 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2345 asserts. fix a few other asserts.
2346 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2347 scm_uniform_vector_ref, scm_array_set_x,
2348 scm_dimensions_to_unform_array): change args in
2349 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2350 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2351 scm_substring_fill_x): likewise.
2352 gsubr.c (scm_gsubr_apply): likewise.
2353 eval.c (SCM_APPLY): likewise.
2355 * eval.c (4 places): replace scm_everr with lgh_error or
2358 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2359 scm_memory_error): new procedures.
2360 scm_everr: deleted. can use scm_wta, dropping first two args.
2361 scm_error: convert NULL subr to SCM_BOOL_F.
2363 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2366 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2369 * error.c, error.h: new error keys: scm_arg_type_key,
2370 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2372 scm_wta: reimplement using lgh_error instead of scm_everr.
2374 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2376 * gdbint.c: scm_lread now has one more argument.
2378 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2379 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2380 loading source from non-file ports, which, e. g., happens when
2381 using the Emacs interface).
2383 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2386 * read.c: Added code for recording of positions of source code
2387 expressions; New functions: recsexpr, scm_lreadrecparen;
2388 _scm_make_srcprops --> scm_make_srcprops
2389 (scm_flush_ws): Removed updating of positions counters. This work
2390 is already done by scm_gen_getc
2392 * read.h: Added prototype for scm_lreadrecparen
2394 * print.c: Added #include "alist.h"
2396 * eval.c: Added #include "hash.h"
2398 * eq.c: Added #include "ramap.h"
2400 * options.c: Documentation fixes.
2402 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
2403 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2404 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2405 --> scm_make_srcprops
2407 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2408 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2409 function calls in the definition of the whash access macros.
2411 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2413 * init.c (scm_boot_guile): Add level of indirection to
2414 scm_boot_guile_1() to ensure that stack base pointer is properly
2415 initialized. There was no guarantee that variable i was the
2416 highest/lowest variable on stack (i.e. the call frame of
2417 scm_boot_guile was not completely protected from gc).
2419 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2421 * ports.h (scm_port_table): put back file_name, it will be used to
2422 support debugging. Undo related changes in fports.c, ioext.c,
2425 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2427 * ports.h (scm_port_table): remove file_name member for now, it seems
2429 * fports.c (scm_open_file): don't set file_name in PTAB.
2430 (prinfport): don't use file_name in PTAB.
2431 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2432 * ports.c (scm_add_to_port_table): don't intialize file_name.
2433 (scm_port_file_name): remove for now.
2434 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2436 * fports.h (scm_mkfile): prototype deleted.
2437 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2439 * debug.c, unif.c: use scm_out_of_range instead of
2440 wta for range errors (ASSERT still needs work).
2442 * error.c, error.h (scm_out_of_range): new procedure.
2444 * error.c, error.h (scm_out_of_range_key): new key.
2446 * posix.c (scm_sync): #else was missing.
2448 * error.c, error.h: append _key to names scm_num_overflow and
2451 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2452 of consing an empty list.
2453 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2454 of macros, saves code and string space.
2455 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2456 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2457 lower case. Rename scm_syserror_m to scm_syserror_msg.
2458 error.h: prototypes for new procedures.
2460 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2462 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2464 * error.c, error.h: setup scm_num_overflow key.
2466 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2467 Remove definition of SCM_OVSCM_FLOW.
2469 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2471 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2472 explicit message and args.
2474 * error.c, error.h, __scm.h: change system_error_sym to
2477 * error.c (system_error_sym): remove leading %% from the Scheme name
2480 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2482 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2484 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2485 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2486 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2487 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2488 renamed. (These were introduced by unsupervised name
2491 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2493 * print.c: Added code for detection of circular references during
2494 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2495 a hook for printing of closures (accessible via print options).
2496 This leads to a split of calls to scm_iprin1 into two classes:
2497 elementary print operations (e. g. the code which prints a smob)
2498 still use scm_iprin1 while top level calls (like scm_display) use
2499 scm_prin1. scm_prin1 begins by clearing the data structure used
2500 to record reference information.
2502 * print.h: Added declarations of scm_prin1 and scm_prlist.
2504 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2506 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2508 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2510 * error.c (err_head): scm_iprin1 --> scm_prin1
2512 * debug.c: Adjusted header comment.
2516 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2518 * strerror.c: Doc fix.
2520 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2522 * gdbint.c (gdb_read): Now possible to run during GC.
2523 (unmark_port, remark_port): New functions.
2525 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2527 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2528 of allocating a new string object. Also, increase size by
2529 the factor 2 instead of 1.5.
2531 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2533 * __scm.h (SCM_P): Corrected to run under traditional C.
2535 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2538 * async.c: Calls to scm_sysintern corrected.
2540 * async.h (scm_async_clock): Redundant declaration removed.
2542 * continuations.c (scm_dynthrow): Redundant declaration removed.
2544 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2545 Definition typos corrected.
2547 * debug.h: Missing declarations of functions in debug.c added
2550 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2551 Missing declarations to functions in eval.c added.
2553 * filesys.c: Possibly uninitialized variable rv.
2555 * gc.h (scm_object_addr, scm_unhash_name): Missing
2556 declarations of functions defined in gc.c added.
2558 * genio.c: Possible typos str_data -> wstr_data. ???
2560 * genio.c: Possibly unintended shadowing of local variable
2561 `int c' (gotos out of scope of inner `c'). ???
2563 * init.c: Uninitialized `SCM last' may be used.
2565 * ioext.h: (scm_sys_isatty_p): Typo.
2567 * list.h (scm_list_head): Missing prototype for function in
2570 * numbers.c (scm_two_doubles): Changed from extern to static
2571 (is used only within numbers.c).
2573 * numbers.h: Repeated declarations removed.
2575 * ports.h (scm_close_all_ports_except): Declaration for the
2576 function defined in ports.c added.
2578 * posix.h: Missing declarations added.
2580 * procs.h (scm_make_subr_opt): Missing declaration added.
2582 * socket.h (scm_sys_gethost): Missing declaration added.
2584 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2586 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2587 Missing declarations added.
2589 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2591 * struct.c: Uninitialized variable `SCM answer' may be used.
2593 * unif.c (l2ra): Declaration prototype.
2595 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2596 defined in ramap.c).
2598 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2599 Redundant declarations removed (they are in ramap.h).
2601 * variable.h (scm_make_udvariable,
2602 scm_make_undefined_variable): Declaration corrected to
2603 correspond variable.c.
2605 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2606 Missing declarations added.
2608 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2610 * Makefile.in (distclean): Don't forget to delete fd.h.
2612 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2614 * fd.h.in, tags.h: Trivial cleanups.
2616 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2617 marksweep.h just declared functions from gc.c.
2618 * gc.h, libguile.h: Don't #include "marksweep.h".
2619 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2620 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2621 dependencies updated.
2623 * libguile.h: Don't #include "files.h"; it's been deleted.
2625 * files.c (scm_sys_delete_file): Moved to filesys.c.
2626 File is now empty; deleted.
2628 * filesys.c: scm_sys_delete_file is now here. Remove
2629 #if's; they seem to rely on remnants of an old portability
2630 regimen. If the problems come up again, solve them properly,
2631 using autoconf. Specifically: Don't test M_SYSV, and #define
2632 remove to be unlink if it's #defined; don't use remove just
2633 because HAVE_STDC_HEADERS is #defined.
2634 * filesys.h: Add declarations for scm_sys_delete_file.
2635 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2636 files.o, files.h, files.c, and files.x.
2637 * init.c: Don't #include "files.h", and don't call scm_init_files.
2639 Use SCM_P instead of PROTO; the latter intrudes on the user's
2641 * params.h: Deleted; definition of SCM_P moved to...
2642 * __scm.h: ... here, where it replaces PROTO macro.
2643 * libguile.h, smob.h: Don't #include "params.h".
2644 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2645 smob.h: Fix prototypes accordingly.
2646 * Makefile.in: Update dependencies.
2647 (inner_h_files): Remove params.h.
2649 * gc.c: #include "gc.h"; every module should include its header,
2650 to let the compiler cross-check the declarations against the
2653 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2654 simpos.h: #include "libguile/__scm.h".
2656 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2658 * init.c: Don't forget to #include smob.h and init.h.
2659 * Makefile.in: Dependencies updated.
2661 * smob.h: Use PROTO instead of #if __STDC__.
2663 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2665 * __scm.h: Doc fixes.
2667 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2668 <angles>; this allows `make depends' to work properly.
2670 * libguile.h: #include smob.h and pairs.h before the others; they
2671 define typedefs used by other headers.
2673 C files should #include only the header files they need, not
2674 libguile.h (which #includes all the header files); the pointless
2675 recompilation was wasting my time.
2676 * Makefile.in (all .o dependency lists): Regenerated.
2677 * libguile.h: Don't try to get a definition for size_t here...
2678 * __scm.h: Do it here.
2679 * _scm.h: Since this is the internal libguile header, put things
2680 here that all (or a majority) of the libguile files will want.
2681 Don't #include <libguile.h> here; that generates dependencies on
2682 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2683 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2684 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2781 * weaks.c: Get "weaks.h".
2783 * stackchk.h: #include "libguile/debug.h",
2785 * print.h, read.h: #include "options.h", since everyone who uses
2786 either of these files will need that.
2788 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2789 anyone who uses this file will need them to define the smob
2790 printing functions. Also, get markers.h, since people will need
2791 to #define the mark functions.
2793 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2794 * ports.h: ... to here.
2796 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2797 don't rely on archaic C default type rules.
2799 * fports.h: #include "libguile/ports.h", since you need that in
2800 order to parse this.
2802 * genio.h: #include "libguile/print.h", because you need that to
2803 parse this; don't bother #including "ports.h", since print.h gets
2806 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2808 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2809 this; it's now a reference to an element of *scm_root.
2811 * debug.h: Don't #include "options.h"; the compiler won't be able
2812 to find that once the headers are installed; instead, #include
2813 "libguile/options.h".
2814 * gc.h: Same, with marksweep.h.
2815 * mbstrings.h: Same, with symbols.h.
2816 * scmhob.h: Same, with _scm.h.
2817 * smob.h: Same, with params.h.
2819 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2820 C files; there's no need for this, and it forces recompilations
2823 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2825 * error.c (scm_error): declare scm_error_callback.
2827 * error.h: prototype for scm_error_callback.
2829 * __scm.h: define lgh_error.
2830 (SCM_SYSERROR): redefine using lgh_error.
2832 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2834 * error.c (scm_error): new procedure.
2836 * error.h: prototype for scm_error.
2838 * Makefile.in (install): install scmconfig.h from the current
2839 directory, not $(srcdir).
2841 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2843 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2844 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2845 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

2851 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2852 vports.h, weaks.h: #include "libguile/__scm.h", not
2853 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2854 dependencies are within libguile properly.
2856 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2858 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2859 when scmconfig.h doesn't exist.
2861 * load.c (scm_sys_try_load): Correct spelling.
2863 * feature.c (scm_loc_features): Make this static.
2865 * Makefile.in (libpath.h): Omit trailing slash from path. We
2866 shouldn't require it of users, so why put it here?
2868 Move code to initialize and search %load-path from ice-9 to C
2869 code, so we can use the load-path to find the ice-9 boot code;
2870 this makes it easier to run Guile without installing it. See
2871 corresponding changes in guile/Makefile.in.
2872 * feature.c: Move stuff concerned with the load path to load.c.
2873 (scm_compiled_library_path): Deleted.
2874 Don't #include libpath.h here.
2875 * feature.h: Don't mention scm_compiled_library_path.
2876 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2877 <sys/stat.h>, and <unistd.h> (if present).
2878 (R_OK): #define if the system hasn't deigned to.
2879 (scm_loc_load_path): New variable.
2880 (scm_init_load_path, scm_sys_search_load_path,
2881 scm_sys_try_load_path): New functions.
2882 (scm_init_load): Initialize scm_loc_load_path to point to the
2883 value cell of the Scheme %load-path variable.
2884 * load.h: Add declarations for scm_sys_search_load_path,
2885 scm_sys_try_load_path.
2886 * init.c: Call scm_init_load_path.
2887 * Makefile.in (feature.o, load.o): Dependencies updated.
2889 * load.c, load.h: Rewrite using PROTO macro.
2891 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2893 * gc.c (scm_cellp): New function: C predicate to determine if an
2894 SCM value can be regarded as a pointer to a cell on the heap.
2896 * gc.h: Added declaration of scm_cellp.
2898 * gdb_interface.h: New file: The GDB interface header from the GDB
2901 * gdbint.c: New file: GDB interface.
2903 * gdbint.h: New file: GDB interface.
2905 * libguile.h: Added #include <libguile/gdbint.h>.
2907 * init.c (scm_boot_guile): Added scm_init_gdbint.
2909 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2910 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2911 found if object files and source are kept separate).
2913 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2915 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2917 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2919 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2920 TK_SRC_DIR; they're not relevant any more.
2922 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2923 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2925 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2927 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2928 search path, so we can find the <libguile/MUMBLE.h> headers.
2930 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2932 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2933 implicit in the .c.o rule.
2934 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2937 Put the library path in a header file, instead of passing it on
2938 the command line in every compilation.
2939 * Makefile.in (libpath.h): New target.
2940 (feature.o): Depend on libpath.h.
2941 (clean): Delete libpath.h.
2942 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2943 * feature.c: ... #include "libpath.h" here.
2944 * .cvsignore: Ignore libpath.h.
2946 Don't install the unwashed masses of Guile header files in the
2947 main #include path; put most of them in a subdirectory called
2948 'libguile'. This avoids naming conflicts between Guile header
2949 files and system header files (of which there were a few).
2950 * Makefile.in (pkgincludedir): Deleted.
2951 (innerincludedir): New variable; this and $(includedir) are enough.
2952 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2953 (installed_h_files): Divide this up. Now this variable lists
2954 those header files which should go into $(includedir) (i.e. appear
2955 directly in the #include path), and ...
2956 (inner_h_files): ... this new variable says which files appear in
2957 a subdirectory, and are referred to as <libguile/mumble.h>.
2958 (h_files): List them both.
2959 (install): Create innerincludedir, not pkgincludedir. Put
2960 the installed_h_files and inner_h_files in their proper places.
2961 (uninstall): Corresponding changes.
2962 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2963 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2964 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2965 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2966 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2967 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2968 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2969 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2970 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2971 vports.h, weaks.h: Find __scm.h in its new location.
2972 * __scm.h: Find scmconfig.h and tags.h in their new locations
2973 (they're both "inner" files).
2975 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2977 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2979 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2981 * posix.c: Doc fixes.
2983 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2985 * socket.c: Don't include a prototype for inet_aton; just use a
2986 K&R style declaration, to avoid warnings but minimize the chance
2987 of conflicts with the system.
2989 On NextStep, <utime.h> doesn't define struct utime, unless we
2990 #define _POSIX_SOURCE before #including it.
2991 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2992 * acconfig.h: New comment text for above CPP symbol.
2993 * configure.in: Call it.
2994 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2996 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2998 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2999 testing for __EMX__.
3001 * posix.c: #include <libc.h>, if it exists.
3003 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
3004 don't even know if the latter exists.
3006 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
3007 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
3008 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
3010 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
3012 (scm_init_posix): Use them when initializing the Scheme constants
3015 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3017 * Makefile.in (libdir, includedir, bindir): Use the
3018 autoconf-supplied values, instead of deriving them ourselves.
3019 (pkgincludedir, datadir, pkgdatadir): New variables.
3020 (install, uninstall): Put the header files in a special
3021 subdirectory, not in the main search path.
3023 * Makefile.in (ALL_CFLAGS): Provide the proper value for
3024 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
3026 * Makefile.in (IMPLPATH): Deleted; never used.
3028 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
3029 on the Tcl/Tk source any more.
3030 (INCLUDE_CFLAGS): Remove references to the above.
3032 * Makefile.in (version.o): Corrected dependencies.
3034 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
3036 * libguile.h: #include "version.h"
3038 * init.c (scm_boot_guile): Call scm_init_version.
3039 * gscm.c (gscm_run_scm): Call scm_init_version.
3041 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
3042 GUILE_VERSION): AC_DEFINE these.
3043 (acconfig.h): #undef the above symbols.
3045 * Makefile.in (libobjs): Add version.o.
3046 (installed_h_files): Add version.h.
3047 (c_files): Add version.c.
3048 (gen_c_files): Add version.x.
3049 (version.o): New rule.
3050 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
3051 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
3052 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
3053 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
3054 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
3055 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
3056 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
3057 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
3058 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
3059 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
3060 weaks.o): Add version.h to dependency lists.
3061 (markers.o): Remove duplicate rule.
3063 * version.h: New file.
3065 * version.c: New file.
3067 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3069 * symbols.c (scm_strhash): scm_downcase is now a function, not an
3070 array; use it appropriately. Since GCC is quite happy to
3071 subscript functions, it never warned us about this; we should use
3072 -Wpointer-arith in the future. I guess we never tested
3075 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3077 * socket.c: Doc and copyright fixes.
3079 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3081 * debug.c: Fixed and improved gdb support.
3083 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3085 * socket.c: Added declaration of inet_aton to avoid compiler
3086 warning. (Hope this solution is correct.)
3088 * stime.c: Added declaration of ftime. (This is missing in
3091 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
3093 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3095 * Makefile.in (c_files): add strerror.c.
3097 * strerror.c: new file from Emacs' sysdep.c.
3098 maybe configure should also check for sys_errlist.
3100 * configure.in (AC_REPLACE_FUNCS): add strerror.
3102 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3104 * debug.c (scm_init_debug): Added initialization for
3105 scm_evaluator_traps.
3107 * debug.h, debug.c: Various name changes.
3108 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
3109 "debug-options-interface". See commentary in options.c.
3111 * options.h, options.c: Options now have documentation strings.
3112 Also added a long explanatory commentary.
3114 * eval.c, print.h, print.c, read.h, read.c: Modifications to
3117 * gscm.c, init.c, root.c, throw.c: Bug fixes:
3118 last_debug_info_frame is now updated in all cases.
3120 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
3123 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3125 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
3126 Added option STACK_CHECKING.
3128 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3130 * Makefile.in: Added {debug,options,srcprop}.{h,c}
3132 * __scm.h: Removed symbols for debugging support.
3134 * acconfig.h: Added symbols for debugging support.
3136 * configure.in: Added user option for debugging support.
3137 --enable-debug will include the debugging code into libguile.a.
3139 * continuations.c (scm_make_cont): Enlarged the #if 0 around
3140 scm_relocate_chunk_to_heap.
3142 * debug.c: New file: low-level debugging support. It also
3143 includes support for debugging with gdb. (The extensions to gdb
3144 are written by Per Bothner at Cygnus.)
3146 * debug.h: New file: low-level debugging support.
3148 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
3149 argument pairs. Extensive modifications to the debugging
3150 evaluator. Added "SECTION:" commentaries to clarify what happens
3151 when, during double compilation. Renamed EVALIMP --> EVALIM.
3152 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
3153 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
3154 the beginning of the file. New procedure: scm_unmemocopy.
3155 Added some global state variables needed by the debugging
3156 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3157 check_entry, check_apply, check_exit, debug_options and
3158 evaluator_traps. New acro: undefine.
3160 * eval.h: Renamed EVAL --> XEVAL.
3162 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3163 --> scm_make_weak_key_hash_table.
3165 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3166 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3168 * libguile.h: Conditionally include debug.h
3170 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3171 scm_object_properties shouldn't return handle. `handle' now gets
3172 initialized in scm_set_object_properties_x. scm_object_properties
3173 doesn't any longer create an entry in scm_object_whash.
3175 * options.c: New file: handling of run time options.
3177 * options.h: New file: handling of run time options.
3179 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
3181 * print.c: New procedure: scm_print_options
3183 * print.h: Defines for print options.
3185 * read.c: New procedure: scm_read_options
3187 * read.h: Defines for reader options.
3189 * root.h: Added scm_source_whash among scm_sys_protects.
3191 * srcprop.c: New file: source properties.
3193 * srcprop.h: New file: source properties.
3195 * throw.c (jbsmob): Jump buffers are now correctly allocated.
3196 (Bug found by A. Green.)
3198 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3200 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3202 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3204 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3206 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3207 and should be called by the final client.
3209 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3211 * gc.h: Use the PROTO macro when declaring functions.
3212 * gc.c: Use the PROTO macro when declaring static functions.
3213 Remove the CPP hair around function definitions.
3215 * gc.c (scm_init_storage): Initialize scm_asyncs.
3217 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3218 preprocessor symbol; "__scm.h" is where it might get #defined.
3219 * __scm.h: Similar: #include <scmconfig.h> before testing
3222 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3224 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3226 * init.c (scm_boot_guile): Add init_func argument; call
3227 (*init_func) instead of calling scm_appinit; it's ucky to
3228 hard-code names for the user's procedures.
3229 * init.h (scm_boot_guile): Adjust declaration.
3231 * __scm.h (PROTO): New macro, for declaring functions with
3234 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3235 eliminate all the __STDC__ conditionals.
3236 (scm_boot_guile): Add declaration.
3237 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3238 Remove __STDC__ conditionals around function definitions; the
3239 declarations in init.h will provide the same information, more
3242 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3243 complain about it in the error message; the error message is
3244 adequate without that note, and there's nothing the user can do
3247 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3249 * Makefile.in (ancillary): Drop def.sed.
3251 * posix.c (scm_init_posix): Use numeric values, rather than
3252 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3253 F_OK. The symbols aren't available on some systems, and I'm
3254 pretty sure their values are fixed by common widespread practice.
3255 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3257 More functions unavailable on some systems.
3258 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3259 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3261 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3262 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3263 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3264 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3265 stub that signals an error as the #else.
3267 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
3269 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
3271 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
3273 * unif.c: include ramap.h.
3275 * read.c (endif): case_insensative_p renamed case_insensitive_p.
3277 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
3279 * ports.c: include sys/ioctl.h.
3281 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
3283 * configure.in: check for sys/ioctl.h.
3285 * ports.c: include <malloc.h> not "malloc.h".
3287 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3289 * fports.c: remove ttyname and tmpnam declarations.
3291 * posix.c: fewer ttyname declarations.
3293 * fports.c: include <string.h> not "string.h".
3295 * init.c, ioext.c: include string.h and unistd.h.
3297 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3299 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
3300 genio.c, simpos.c, vports.c: include string.h.
3302 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
3304 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
3306 (scm_addr_buffer_size): change type from scm_sizet to int.
3307 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
3308 from scm_sizet to int.
3310 * error.c: include unistd.h.
3312 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
3315 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
3317 * __scm.hd, def.sed: deleted.
3319 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
3321 Changes for NeXT, suggested by Robert Brown.
3322 * configure.in: Call AC_TYPE_MODE_T.
3323 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
3324 NeXT. Put header file list in alphabetical order.
3325 * configure, scmconfig.h.in: Regenerated.
3326 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
3328 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
3331 * acconfig.h: New file, providing documentation for the CPP
3332 symbols defined in configure.in
3333 * acconfig-1.5.h: Removed; superceded by the above.
3335 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
3337 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
3339 * fports.c (scm_open_file): don't return #f, throw error.
3341 * ioext.c (fileno): renamed from %fileno.
3342 (soft-fileno): deleted.
3344 * ports.c (scm_port_revealed): don't need to check for -1 from
3346 (scm_set_port_revealed_x): return unspecified, not #f.
3348 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3350 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3352 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3354 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3356 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3358 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3359 This is necessary on Ultrix, and doesn't hurt portability.
3361 * Makefile.in (dist-dir): New target, implementing a new dist system.
3362 (installed_h_files): Put in alphabetical order.
3363 Remove duplicate entries for markers.h and unif.h.
3364 (c_files): Remove duplicate entries for markers.c.
3365 (ancillary): Renamed from anillery; all uses changed. Remove
3366 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3367 Remove all the ../doc/* files; doc/Makefile.in handles that.
3369 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3371 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3372 every if must have an else, or else the whole command has a

3442 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3444 * gscm.h: gscm_mkarray eliminated (presumably was not being used

3462 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3463 handled correctly (SCM_FREEP was applied to them) -- test for

3632 initialization to fix a race condition.
3634 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

3661 The weird symbol syntax is also a bit bogus (emacs doesn't quite
