1 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
3 * script.c (scm_find_executable): Use prototype-style definition
4 here; apparently it's not quite right to have const in a prototype
5 and then use a K&R declaration. I wonder if stuff like this will
6 go away if we compile with -Wrequire-prototypes, or whatever that
7 is... (thanks to Bernard URBAN)
9 * scmhob.h: New text from Bernard URBAN.
11 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
13 * script.c: Don't #define const on hpux. Configure takes care of
14 this. (Thanks to Larry Schwimmer.)
16 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
17 decide whether to #include <unistd.h>, instead of listing a bunch
18 of systems. Don't #include stdio twice. Removed dyked-out
19 definition of scm_find_impl_file.
21 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
23 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
24 library version info to 1:0.
25 * Makefile.in: Regenerated.
27 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,
28 gdb_interface.h, gdbint.c, gdbint.h, gh_data.c, gh_init.c,
29 gh_io.c, gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c,
30 init.c, net_db.c, options.c, options.h, ports.c, print.c, read.c,
31 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
32 throw.c: Update copyright years; these files have been worked on
33 significantly in 1997, but only had copyright years for 1996.
34 Also, change name of copyright holder on some from Mikael
35 Djurfeldt to Free Software Foundation; he has signed papers
36 assigning the changes to the FSF.
38 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
39 reason not to give the user the option.
41 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
42 Return #f on end-of-file when scanning table (i.e. when called
43 with no arguments). Try to catch errors, when we can.
44 * posix.c (scm_getgrgid, scm_getpwuid): Same.
46 * script.h (scm_shell_usage, scm_compile_shell_switches): New
47 external declarations. These are useful.
49 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
51 * posix.c: don't include <sys/select.h> or define macros for
52 select, since they were not used in this file.
54 * filesys.c (scm_select): make the fifth parameter microseconds,
55 not milliseconds. let the fourth parameter be either a real value
56 or an integer or #f. The first, second and third arguments can
57 now be vectors: the type of the corresponding return set will be
59 (set_element, get_element): new static procedures.
61 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
63 * strports.c (scm_eval_string): New function.
64 (scm_eval_0str): Trivially re-implemented in terms of
66 * strports.h (scm_eval_string): New extern decl.
68 * net_db.c (h_errno): Add extern decl for this.
70 * fports.c (local_pclose): New function.
71 (scm_pipob): Use it in the initializer here.
74 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
75 Use a meaningful error message when signalling an error. For
76 this, scm_gethost must check h_errno rather than errno.
78 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
80 * Makefile.in: Regenerated, using automake-1.1p.
82 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
84 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
87 * script.c (scm_compile_shell_switches): don't append (quit) if
89 (scm_shell): call scm_exit_status and exit on the result of the
92 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
94 Ensure that shared substrings are handled properly when passed to
95 a system call or other foreign function. Many thanks to Tim
97 * symbols.h (SCM_COERCE_SUBSTR): new macro.
98 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
99 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
100 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
101 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
102 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
103 (scm_display_error_message): use RO macros when strings may be RO.
104 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
105 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
106 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
107 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
108 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
109 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
110 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
111 scm_strftime), vports.c (scm_make_soft_port): use
112 SCM_COERCE_SUBSTR to make sure shared substrings are
115 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
117 * error.c (scm_error): Add newline to error message.
119 * init.c (scm_init_standard_ports): Doc fix.
121 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
123 * dynl-shl.c: Completely replaced with new code from Bernard
126 * script.c (scm_ice_9_already_loaded): New variable.
127 (scm_compile_shell_switches): Use it.
129 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
131 * filesys.c (scm_input_waiting_p): add missing third argument to
134 * stime.c (scm_localtime): copy the result of localtime before
135 calling gmtime in case they share a buffer.
136 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
139 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
141 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
143 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
145 * Makefile.am (check-local): New target, which causes 'make check'
146 to run gh_test_c and gh_test_repl, with some trivial input.
147 * Makefile.in: Rgnrtd.
149 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
151 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
154 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
156 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
157 sure how this was supposed to work.
158 (scm_async_click): don't send SCM_TICK_SIGNAL.
159 (scm_init_async): don't initialize %tick-thunk.
161 * the following change doesn't affect the Scheme interface:
162 gc-thunk is called at the end of garbage collection. however it's
163 no longer implemented by pretending it's a signal.
165 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
166 system async corresponding to scm_gc_thunk.
167 * async.h: declare scm_gc_async.
168 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
169 gc-thunk directly, instead of going through a signal handler.
170 (scm_gc_async): new variable, points to the GC system-async.
171 (scm_init_async): save the GC async as scm_gc_async instead
172 of using system_signal_asyncs.
173 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
175 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
177 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
178 Don't screw up if we're interrupted.
179 * Makefile.in: Regeneradet.
181 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
183 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
185 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
186 we're not using AM_INIT_GUILE_MODULE any more.
187 * Makefile.in: Reneregated.
189 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
191 Functions for finding variable bindings, grace à Tim Pierce.
192 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
193 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
195 Get 'make dist' to work again.
196 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
197 * Makefile.in: Regenerated, like a surry without a fringe on top.
199 Changes for reduced Guile distribution: one configure script,
201 * configure.in, configure: Removed.
202 * acconfig.h, acinclude.m4: Moved to parent directory, where the
203 real configure script lives.
204 * Makefile.in, scmconfig.h.in: Regenerated.
206 * init.c: #include "script.h", to get prototype for script.c's
209 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
211 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
212 scm_must_malloc, not raw malloc.
214 * script.c (scm_compile_shell_switches): Dyke out debugging output
217 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
219 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
221 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
222 system has them. Hope this is safe. Previously
223 sys/timeb.h was included if HAVE_FTIME was defined or if
224 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
225 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
227 * ioext.c (scm_setfileno): add missing third argument to
230 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
232 * eq.c (scm_equal_p): Correctly compare strings of different
233 varieties. (Thanks to Tim Pierce.)
235 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
237 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
238 #! block comment must occur on a line all by itself.
240 Move most of the guts of shell command processing into libguile,
241 so guile.c can be very small (and eventuallly auto-generated. (I
242 mean, generated mechanically, not self-generated. Hmm.))
243 * guile.c, script.c, script.h: New source files.
244 * init.c (scm_boot_guile_1): Call scm_init_script.
245 * libguile.h: #include "script.h".
246 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
247 targets, for new executable.
248 (libguile_la_SOURCES): Mention script.c.
249 (modinclude_HEADERS): Add script.h.
250 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
251 not dynamic linking is enabled. This is because we're generating
252 executables now. Move CY_AC_WITH_THREADS call after those, so the
253 values of cy_cv_threads_libs captures the libs chosen above.
254 * Makefile.in, configure, aclocal.m4: Regenerated.
256 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
257 We don't maintain this interface any more, and it just confuses
260 * alloca.c: #include <scmconfig.h>, not <config.h>.
261 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
262 it'll get included in disties.
264 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
266 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
267 be distributed, because they confuse people.
268 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
270 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
272 * configure.in: check for presence of gethostent (not present on
274 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
275 * configure, scmconfig.h.in: Regenerated.
277 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
279 * backtrace.c (scm_backtrace): Split message string across
280 newlines properly. GCC is more tolerant of this than other
283 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
285 Merge threads directory into libguile.
286 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
287 threads.h: New source files.
288 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
289 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
291 (modinclude_HEADERS): Add threads.h, coop-defs.h.
292 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
293 coop-threads.c.cygnus, coop-threads.h.cygnus.
294 * configure.in: If we're using threads, include threads.o in
296 * _scm.h, libguile.h: threads.h lives in this directory now.
297 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
298 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
299 currently used, but brought along for information's sake.
300 * ChangeLog-threads: log from old 'threads' directory.
301 * Makefile.in, configure: Rebuilt.
303 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
305 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
308 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
310 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
312 Merge GH interface library into libguile.
313 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
314 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
315 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
316 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
318 (EXTRA_libguile_la_SOURCES): ... here.
319 (pkginclude_HEADERS): Add variable, to get gh.h installed.
320 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
321 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
322 New variables, describing how to build the gh test programs.
323 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
324 build the test programs, and we probably should have been linking
325 libguile.la against them all along, to support AIX shared libs.
326 Add cflags for threads to CFLAGS; add libs for threads to new
327 variable THREAD_LIBS, used in Makefile.am.
328 * ChangeLog-gh: log from old `gh' subdirectory.
329 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
331 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
333 * acconfig.h: Undo change of Apr 9; including the definition of
334 PACKAGE in the guile headers conflicts with applications' own
336 * scmconfig.h.in: Regenerated.
338 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
340 * filesys.c (scm_fcntl): New function from Roland McGrath.
341 (scm_init_filesys): New symbols for use with fcntl.
342 * filesys.h: Added prototype.
344 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
345 when PROC is receiving no arguments.
347 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
349 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
350 have S_IFSOCK. This is the case under Ultrix.
352 * posix.c (scm_status_exit_val, scm_status_exit_val,
353 scm_status_term_sig, scm_status_stop_sig): Modified to work with
354 Ultrix versions of WIFSTOPPED, etc., which assume that their
355 arguments are lvalues (hmm).
357 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
361 * throw.c: Doc fixes; rearranged.
363 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
365 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
367 * acconfig.h: Added entry for PACKAGE.
368 * scmconfig.h.in: Regenerated.
370 Changes to work with automake-1.1n, which has better libtool support.
371 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
372 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
374 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
376 * Makefile.in: Rebuild.
378 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
380 * stime.c (scm_mktime): take an optional zone argument.
381 (scm_localtime): check putenv return value.
382 (scm_strftime, scm_strptime): moved from posix.c. move #include
384 stime.h, posix.h: update prototypes.
385 (bdtime2c, setzone, restorezone): new static procedures.
386 (scm_mktime, scm_strftime): use them.
387 (scm_strftime): don't call mktime before strftime. Use
388 filltime for return value.
389 (filltime): convert NULL zname to #f.
390 (scm_strptime): return a count of characters consumed, not
391 the remaining string.
393 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
395 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
396 (scm_mktime): likewise.
398 Uncomment localtime and mktime.
400 * configure.in: add AC_STRUCT_TIMEZONE.
402 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
404 * stime.c (scm_init_stime): don't define ticks/sec.
405 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
406 return value problem and is still portable.)
408 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
410 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
411 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
412 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
413 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
414 cpp_err_symbols.c): Corresponding changes.
415 * Makefile.in: Regenerated.
417 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
419 * posix.c (scm_putenv): don't check HAVE_PUTENV.
420 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
421 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
422 * putenv.c: new file, from sh-utils 1.12.
424 * posix.c (scm_environ): use malloc in place of scm_must_malloc
425 since allocation isn't for Scheme objects.
426 (scm_putenv): copy strings before placing in the environment.
428 * stime.c (scm_current_time): throw an error if time returns -1,
429 instead of returning #f.
430 (scm_get_internal_real_time, scm_get_internal_real_time): use
431 scm_long2num for return value instead of SCM_MAKINUM.
433 * stime.h: prototypes updated.
435 * stime.c (scm_time_in_msec): apparently unused, deleted.
437 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
439 * configure.in: check for gettimeofday.
441 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
442 which may be more usefully portable than a gettimeofday interface.
444 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
446 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
448 * Makefile.in: Regenerated.
450 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
452 * stime.c (filltime): recovered static procedure.
453 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
456 * posix.h: add prototype for scm_close_pipe, remove prototypes for
457 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
459 * posix.c (scm_mknod): split the mode argument into type and perms
460 arguments, like the extra fields returned by stat.
462 * fports.c (scm_pipob): set the close, free and print procedures.
463 (scm_close_pipe): new procedure.
465 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
466 define them in boot-9.scm
468 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
470 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
471 wan't defined. Don't include fd.h.
473 * Previously fd.h was regenerated whenever configure was run,
474 forcing a couple of files to be recompiled.
476 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
477 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
478 Check for _fileno as well as _file.
480 * ioext.c: don't fd.h.
481 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
484 * Change the stratigy for getting information about errno
485 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
486 generating lists of symbols during the build process, which will
487 not always work, include comprehensive lists in the distribution.
488 To help keep the lists up to date, the "check_signals" and
489 "check_errnos" make targets can be used.
491 * configure.in: don't check for a command to extract errno codes.
492 * Makefile.am: update file lists, remove errnos.list and errnos.c
493 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
494 check_errnos targets.
495 (CLEANFILES): remove errnos.c and errnos.list, add
496 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
497 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
498 * errnos.default: deleted.
499 * cpp_signal.c: new file.
500 * cpp_errno.c: renamed from errnos_get.c.
501 * cpp_err_symbols, cpp_sig_symbols: new files.
502 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
503 * error.c (scm_init_error): #include cpp_err_symbols instead of
505 * posix.c (scm_init_posix): don't intern signal symbols. #include
508 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
510 * strop.c (scm_i_index): allow the lower bound to be equal to the
511 length of the string, so a null string doesn't always give an error.
513 * posix.h: new prototypes.
514 * posix.c (scm_status_exit_val, scm_status_term_sig,
515 scm_status_stop_sig): new functions, as in scsh. They break down
516 process status values as returned by waitpid.
518 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
520 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
521 configure doesn't know about it.
523 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
525 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
527 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
528 which defines C variables with global linkage.
530 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
532 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
535 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
537 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
538 has time to check why this doesn't work well with continuations.
540 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
542 * Fix shell syntax error; some shells won't tolerate
543 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
545 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
547 * posix.c (scm_uname): throw an error if uname fails instead
550 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
552 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
555 * async.c (scm_ints_disabled): definition moved from error.c.
557 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
559 * acconfig.h: Removed PACKAGE.
561 * scmconfig.h.in: Regenerated.
563 * snarf.h: g++ says it's non-portable not to specify the first
564 argument in a varargs declaration. I introduced the first
565 argument by using preprocessor conditionals.
567 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
569 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
570 (scm_freopen): use RO string macros for filename and modes.
571 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
573 * posix.c (scm_getgrgid): simplify conversion of name to C string.
574 (scm_mknod): use RO string macros for path.
576 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
577 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
579 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
580 use SCM_ROSTRINGP and SCM_ROCHARS.
582 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
584 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
587 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
588 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
589 support for byte vectors.
591 * print.c (scm_iprin1): Limit number of vector elements printed
592 according to pstate->length.
594 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
596 * backtrace.c (scm_display_error_message): don't segv if message
599 * error.h: prototype for scm_error_scm.
601 * error.c (scm_error_scm): new procedure, reimplements scm-error
602 in C and uses scm_error.
604 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
606 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
607 pointer to the Scheme variable read-hash-procedures and intern it
608 in scm_init_read. Modify scm_read_hash_extend and
609 scm_get_hash_procedure to use the pointer.
611 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
613 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
614 (SCM_KEYWORD_STYLE): defined.
616 * read.c (scm_read_opts): add a keywords option. This isn't a
617 boolean option, in case someone wants to add support for DSSSL
619 Setup scm_keyword_prefix symbol.
620 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
622 I've left keyword support disabled by default, since it doesn't
623 seem to break the module system and it gives R4RS standard behaviour.
624 It can be reactivated with (read-set! keywords 'prefix).
626 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
628 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
629 before constructing arbiter.
631 * eval.c (scm_m_define): Bugfix: Check that the object is a
632 closure before setting the procedure property!
634 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
636 * ports.c: Removed `ungetc-char-ready?'.
638 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
640 * read.c (scm_init_read): intitialise scm_read_hash_procedures
641 (idea from Mikael: make it a pair so scm_permanent object only
643 (scm_read_hash_extend): don't call scm_permanent_object.
644 (ideas from Mikael): if chr is already in the list, replace its
645 procedure instead of appending it again. If proc is #f, remove
647 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
649 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
651 * gdbint.c (gdb_read): update scm_lreadr usage.
653 * load.h: update prototypes.
655 * load.c (scm_primitive_load, scm_read_and_eval_x,
656 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
658 * read.h: add prototype for scm_read_hash_extend. Change args for
661 * read.c (scm_read_hash_procedures): new variable.
662 (scm_read_hash_extend): new procedure.
663 (scm_get_hash_procedure): new procedure.
664 (scm_lreadr): use scm_get_hash_procedure instead of an argument
665 for extended # processing.
666 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
667 scm_read_token): remove case_i, sharp arguments. Change callers.
669 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
671 * read.h (SCM_N_READ_OPTIONS): increase to 3.
672 (SCM_CASE_INSENSITIVE_P): define.
674 * read.c: add case-insensitive option to scm_read_opts.
675 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
676 to determine whether to convert symbol case.
677 (default_case_i): definition removed.
678 * read.c (scm_read_token): if case_i, downcase ic before doing
681 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
683 * configure.in: Added configuration option `guile-debug'.
684 Configure with --enable-guile-debug if you want a bunch of extra
685 functions used for debugging when developing Guile.
687 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
689 * procs.c (make-cclo): New undocumented debugging procedure: Make
690 compiled closure with internal procedure PROC and length LENGTH.
691 Only compiled if GUILE_DEBUG is defined.
693 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
695 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
697 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
699 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
700 with 3 or more args internally to the evaluator.
702 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
704 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
705 with 3 or more args internally to the evaluator. This is mainly
706 because we don't want to pass entry and exit points of the
707 debug support twice, but it also seems to increase the speed of
708 the evaluator for such calls (e. g. (+ 1 2 3)).
710 * backtrace.c (scm_display_application): New procedure:
711 display-application; Set fancy printing parameters individually
712 for different types of display (backtrace, error, application).
713 (These should of course be customizable!)
715 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
716 clear the CHECK-flags.
718 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
720 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
722 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
724 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
725 from pairs with a GLOC in the car.
727 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
728 otherwise `symbol-hash' will behave badly.
729 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
730 we get segmentation fault!
732 * symbols.c: Added #include "weaks.h". New functions:
733 `builtin-bindings' and `builtin-weak-bindings'. (These will be
734 moved to an extraneous library when we split libguile.)
736 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
738 * filesys.c (scm_stat): stat now takes fport arguments too as
739 documented in the manual.
741 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
743 * debug.c (scm_single_step): Bugfix: Call continuation with
744 scm_call_continuation instead of throwing to it.
746 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
748 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
749 argument wasn't declared to be optional.
751 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
753 * stime.c (scm_init_stime): Add feature "current-time".
755 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
757 * throw.h: prototype for scm_exit_status.
758 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
759 args to derive an exit status. Allows (quit) to work from a
761 (scm_exit_status): new function.
764 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
766 * eval.c (scm_deval): Removed some old code.
767 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
769 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
772 * symbols.c (msymbolize): Bugfix: Must initialize property list to
775 * procs.c: Introduce the existent C function scm_thunk_p at the
776 Scheme level as well.
778 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
780 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
781 used from C to easily lookup the value of a symbol in the current
784 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
786 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
787 scm_init_unif in this file. This will also fix a previous problem
790 * configure.in: Added AM_MAINTAINER_MODE
792 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
794 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
797 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
799 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
800 source files that are not always included in libguile but should
801 have their dependencies calculated by automake. This variable is
802 recognized by automake, no further magic is needed.
803 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
804 to deal exclusively with *.lo files, as it seems. The *.o files
805 are built automatically when the corresponding *.lo file gets
808 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
810 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
813 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
815 * unif.c (scm_array_set_x): minor change to argument error checking.
817 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
819 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
820 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
821 They should only be included in the library at configure.in's
823 (libguile_la_LDADD): Include the appropriate .lo files here.
824 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
825 so we know when to build them (and their .lo bretheren).
826 * configure.in (LIBLOBJS): New substituted variable. We let
827 configure decide which .o files to include in LIBOBJS, and then
828 put the corresponding list of .lo files in LIBLOBJS. The latter
829 is what we pass to libtool.
830 * Makefile.in, configure: regenerated.
832 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
834 * symbols.c (scm_sysintern0): New function. Contains the core of
835 old scm_sysintern but doesn't take a second value argument.
836 (scm_sysintern): Now uses scm_sysintern0.
837 (scm_sysintern_no_module_lookup): Renamed to
838 scm_sysintern0_no_module_lookup and doesn't take a second value
841 * symbols.h (scm_sysintern0: Added declaration.
843 * options.c (scm_init_opts): Use scm_sysintern0 instead of
844 scm_sysintern when interning option keys. Otherwise we risk
845 destroying the values of already interned variables.
847 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
848 scheme-level boolean (use SCM_NFALSEP).
850 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
852 (scm_backtrace): New function. (C version of old function from
853 boot-9.scm) Motivation: Make it possible to display backtraces
854 without depending on boot-9.scm. (I'm uncertain if this
855 motivation is good enough...)
857 * root.h (scm_root_state): Add member the_last_stack_var.
858 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
860 * root.c (mark_root): Mark scm_the_last_stack_var.
862 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
865 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
867 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
868 1. mark_lazy_catch didn't mark the smob.
869 2. Both functions above have standard variants:
870 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
871 free_lazy_catch --> scm_free0.
873 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
875 * throw.c (scm_internal_lazy_catch): New function.
876 (scm_lazy_catch): Rewritten to use it.
877 (scm_ithrow): Handle the new lazy catch representation.
878 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
879 that doesn't have a jmpbuf is a lazy catch clause.
880 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
881 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
882 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
884 (scm_init_throw): Register the new lazy-catch smob type.
885 * throw.h (scm_internal_lazy_catch): decl for new function.
887 * throw.c (scm_internal_catch): Doc fixes.
889 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
890 configure.in. Including this might cause problems if applications
891 that link against libguile include their own copies of alloca, but
892 if they're using autoconf, they should be adding libguile to LIBS
893 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
894 the copy in libguile, and things will be okay. (I think.)
896 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
898 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
900 strop.h: move prototypes too.
902 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
904 * posix.c (scm_init_posix): don't intern EINTR since it's now done
907 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
908 etc. I deleted them from filesys.c long ago, but didn't
909 notice they were here too (although ineffective since
910 sys/stat.h wasn't included).
912 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
914 * eval.c: Don't define alloca in GCC case. gcc will automatically
915 use __builtin_alloca if appropriate.
917 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
919 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
920 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
921 that values of automatic variables are preserved. See comments
922 for safe_setjmp for details.
924 Change from Thomas Morgan:
925 * variable.c: Include eq.h.
926 (var_equal): New function.
927 (variable_smob): Use var_equal as the discriminator for variables.
929 * throw.c (s_throw): Remove extraneous declaration.
931 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
932 * eval.c: Add necessary CPP cruft to support that.
933 * configure, Makefile.in, scmconfig.h.in: regenerated.
935 Change from Thomas Morgan:
936 * procprop.c (scm_procedure_properties): Convert the Scheme
937 boolean returned by scm_procedure_p into a C boolean before using
938 it as a condition for SCM_ASSERT.
939 (scm_procedure_property): Likewise.
941 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
942 indications of Unixness.
945 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
947 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
949 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
951 * read.c (scm_lreadr): use scm_misc_error to improve one of the
952 "unknown # object" error messages.
954 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
955 (scm_i_index) and declare it static. Add a 'direction' argument
956 to indicate what way the search should go.
957 (scm_i_index): throw out-of-range error instead of wrong-type-arg
959 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
960 strop.h: remove scm_i_index, scm_i_rindex prototypes.
962 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
964 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
966 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
967 to avoid clash with various scsh forks.
969 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
971 The following two changes (ramap.c, throw.c) are motivated by the
972 apparent unportability of forward declarations of static arrays of
973 the form `static foo bar[];'.
975 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
976 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
978 * throw.c (scm_throw): Moved above scm_ithrow.
980 * options.h: Removed the extern declarations of scm_yes_sym and
981 scm_no_sym since these are static.
983 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
985 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
987 * Makefile.am: remove AWK=@AWK@.
988 Add a rule for generating errnos.list.
989 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
991 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
992 don't extract errnos, just set a variable (avoids the
993 need to recompile error.c just because configure is run.)
995 * unif.h: update prototypes.
996 * unif.c (scm_uniform_array_read,write): change the offset and
997 length arguments to start and end, for consistency.
999 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
1001 * ioext.h: update prototypes.
1002 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
1003 scm_read_line_x, it's a more general procedure using an
1004 interface from scsh. read-line and read-line! are now defined
1006 Note that the new read-line trims the terminator
1007 by default, previously it was appended to the returned string. An
1008 optional argument specifies how to process the terminator (scsh
1009 compatible). For the old behaviour: (read-line port 'concat).
1010 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
1011 returns a pair, but is converted to multiple values if the scsh
1014 socket.h: update prototypes.
1015 * socket.c (scm_recvfrom): for consistency with other procedures,
1016 take start and end as separate optional arguments.
1017 (scm_recv, scm_recvfrom): don't allow the second argument
1018 to be a size, only a buffer. Change the scheme names to
1019 recv! and recvfrom!. Don't return the buffer.
1021 * ioext.h, posix.h: move prototypes too.
1022 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
1023 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
1024 "read.h" and "unif.h".
1025 * ioext.c: include "chars.h"
1027 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
1029 * dynl.c: The dynamic linking and module registration functions
1030 are now defined even when dynamic linking is not available for the
1031 host system. Some of their functionality can be done without
1032 dynamic linking; when it's really needed, they throw errors.
1034 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
1036 * configure.in: Only define DYNAMIC_LINKING when one of the system
1037 dependent functions is detected.
1038 * dynl.c (scm_dynamic_func): New function to get the address of a
1039 function in a dynamic object.
1040 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
1041 produced by scm_dynamic_func as the thing to call.
1043 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
1045 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
1046 (scm_register_module_xxx, scm_registered_modules,
1047 scm_clear_registered_modules): New functions.
1049 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
1051 * symbols.c (scm_sysintern): Renamed to
1052 scm_sysintern_no_module_lookup.
1053 (scm_sysintern): New function to take the place of the old
1054 scm_sysintern. It uses the current toplevel lookup closure to give
1055 the symbol its value. This is a temporary hack to put packages
1056 like gtcltk into their own module.
1057 (scm_can_use_top_level_lookup_closure_var): New variable to tell
1058 us whether `scm_top_level_lookup_closure_var' has been initialized
1060 * eval.c (scm_init_eval): Set it.
1062 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1064 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
1065 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
1067 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
1069 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
1070 scm_sys_dup): deleted: FD capability will be added to other
1072 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
1073 scm_fd_free, fd_smob, scm_intern_fd.
1074 (scm_open): renamed from scm_sys_open. Return a port instead of
1075 an FD object. Make the mode argument optional.
1076 (scm_sys_create): deleted, it's just a special case of open.
1077 (scm_init_filesys): move interning of constants O_CREAT etc.,
1078 here (were previously using SCM_CONST_LONG macro).
1079 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
1081 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
1082 include "fports.h" and <stdio.h>
1083 (scm_stat, scm_select): don't support FD objects.
1085 * error.h: adjust scm_syserror_msg prototype.
1086 * error.c (scm_syserror_msg): take an extra argument for errno.
1087 Using the global value didn't always work, since it could be
1088 reset by procedure calls in the message or args arguments.
1090 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
1091 I don't understand why the check was there (and what about the
1094 * strop.c (scm_string_copy): allow shared substrings to be copied.
1096 * unif.h: corresponding change to prototypes.
1097 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
1098 recognize two new optional arguments: offset and length. Allow
1099 the port argument to be an integer (file descriptor, for scsh).
1100 Include <unistd.h> for "read" prototype.
1102 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1104 * socket.c: don't include filesys.h.
1106 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
1108 * Makefile.am: add AWK=@AWK@ (?)
1110 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
1112 Add a rule to generate errnos.c from errnos.
1113 * error.c (scm_init_error): include errnos.c.
1114 * errnos_cnvt.awk: new file, converts the list of errno codes to
1116 * errnos_get.c: new file.
1117 * errnos.default: new file, contains errnos to try if they can't
1118 be extracted from errno.h.
1119 * configure.in: if using GCC, try and extract errno codes from
1123 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
1125 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
1126 * Makefile.am: Made libguile into a libtool library.
1127 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
1128 Set libtool_libs to indicate that libguile is a libtool library.
1129 See guile/ChangeLog for details.
1130 * .cvsignore: ignore "*.lo", the libtool library objects.
1132 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1134 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
1135 use htons in getservbyport argument.
1137 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1139 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
1140 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
1143 * objprop.c (scm_object_property): No need to take the CDR of the
1144 value returned by scm_object_properties, since Aug 20 change.
1146 * configure.in: When checking for struct linger, #include
1147 <sys/types.h> as well as <sys/socket.h>. I've never known
1148 <sys/types.h> to cause any portability problems, and Solaris's
1149 <sys/socket.h> needs it.
1150 * configure: Rebuilt.
1152 I think the Sun compiler has chosen a perverse way to interpret
1153 ANSI declarations combined with K&R definitions. We'll
1154 appease it a little bit. But when it invades France, we fight.
1155 * print.c (scm_iprlist): Change 'tlr' argument to an int.
1156 * print.h (scm_iprlist): Here too.
1157 * numbers.c (scm_divbigdig): Change definition to match
1158 declaration in numbers.h.
1159 * unif.c (scm_makflo): Change definition to match declaration in
1162 * init.c (scm_boot_guile): Don't return the value of
1163 scm_boot_guile_1. This function doesn't return a value;
1164 scm_boot_guile_1 doesn't return a value (or return at all).
1166 * eval.c (unmemocopy): Add a semicolon to appease the Sun
1169 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
1170 compile. I have a feeling this function is a bad idea anyway ---
1171 one should always test for features, not systems.
1173 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
1174 semicolons. Only pure luck kept this from being noticed earlier.
1176 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
1178 * socket.c (scm_recvfrom): Added missing semicolon.
1180 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1182 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
1183 the buffer and start and end positions for scsh networking
1186 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
1188 * configure.in: Revert previous change to this file; the problem
1189 is due to transient automake weirdness.
1190 * configure: Rebuilt.
1192 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
1193 PLUGIN/guile.libs. configure generates the latter from the former.
1194 * Makefile.in: Rebuilt.
1196 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
1197 need this if we install scripts, like guile-snarf.
1198 * configure: Rebuilt.
1200 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1202 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
1204 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
1206 * socket.c (scm_addr_vector): fix faulty scm_listify.
1208 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
1210 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
1211 style block comment is no longer considered an error.
1213 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
1215 * PLUGIN/guile.libs.in: New file.
1216 * PLUGIN/guile.libs: Removed from repository.
1217 * configure.in: Create PLUGIN/guile.libs from
1218 PLUGIN/guile.libs.in. This is for including additonal libraries
1219 needed for dynamic linking.
1220 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
1221 instead of PLUGIN/guile.libs.
1223 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
1225 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
1227 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
1228 occurrences of the given element from the list, not just the
1229 first. This is how the Emacs Lisp functions behave, how the
1230 analogous Common Lisp functions behave, and (I believe) how the
1231 older Maclisp functions worked. I realize that this change may
1232 break code, but it seemed better to break it before the Guile
1235 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
1236 Their prototypes were already present in gc.h, but they weren't
1238 (scm_init_storage): Initialize scm_protects.
1239 * root.c (scm_protects): New element of scm_sys_protects.
1241 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
1243 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1245 * libguile.h: Added #include "libguile/net_db.h".
1247 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
1248 30 change. That file is only meant for communication between the
1249 configuration process and load.c. If code linked against libguile
1250 wants to get at the paths mentioned in libpath.h, it can call
1251 functions declared in load.h.
1253 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1255 * libguile.h: Removed #include "libguile/fdsocket.h"
1257 * net_db.c: Added #include <sys/socket.h>.
1259 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
1261 * filesys.c (scm_input_waiting_p): use select in preference to
1262 FIONREAD, since the latter doesn't detect EOF.
1263 Throw error if neither select nor FIONREAD available.
1265 * socket.c (scm_connect): take a port, not a fd object.
1266 (scm_fill_sockaddr): throw an error if fam is not recognised.
1267 (scm_bind): use scm_fill_sockaddr.
1268 (scm_listen): take a port, not a fd object.
1269 (scm_accept): take and return a port. return #f in the car if
1270 address can't be got
1271 (scm_sock_fd_to_port): new procedure.
1272 (scm_socket): use scm_sock_fd_to_port.
1273 (scm_addr_vector): throw error if unrecognised address type.
1274 take an extra argument with the calling procedure name.
1275 (scm_getsockname): take a port. return #f if address can't be got.
1276 (scm_getpeername): take a port. return #f if address can't be got.
1277 (scm_recvfrom): take a port. return #f for address component if can't
1279 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
1280 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
1282 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
1284 * throw.c (scm_internal_catch): Make body funcs and handler funcs
1285 use separate data pointers, to allow them to be designed
1286 independently and reused.
1287 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
1288 Renamed from catch_body, catch_handler, and uncaught_throw; made
1290 (struct scm_catch_body_data): Renamed from catch_body_data; moved
1292 (scm_catch): Use the above.
1293 (scm_throw): Don't bother printing a message for an uncaught
1294 throw; we establish a default handler in init.
1295 * throw.h (scm_internal_catch): Prototype updated.
1296 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
1298 (struct scm_body_thunk_data): New structure, used as data
1299 argument to scm_body_thunk.
1300 * init.c (struct main_func_closure): New structure, packaging up
1301 the data to pass to the user's main function.
1302 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
1303 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
1304 scm_internal_catch to establish a catch-all handler, using
1305 scm_handle_by_message. This replaces the special-case code in
1307 (invoke_main_func): Body function for scm_internal_catch; invoke
1308 the user's main function, using the main_func_closure pointer to
1309 decide what to pass it.
1310 * root.c (struct cwdr_body_data): Remove handler_proc member.
1311 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
1312 (cwdr_handler): Removed.
1314 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1316 * socket.h (SCM_P): update bind prototype.
1317 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
1318 include "feature.h".
1319 (scm_socket): return a port, not a file descriptor object.
1320 include "fports.h" and <unistd.h>
1321 (scm_bind): take a port, not a file descriptor object.
1322 take an extra argument for address args.
1324 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
1325 INADDR_NONE, INADDR_LOOPBACK.
1327 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1329 * init.c: include net_db.h and not fdsocket.h.
1330 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
1332 * Makefile.am: corresponding changes.
1333 * socket.h: renamed from fdsocket.h, fix names.
1334 * net_db.h: renamed from socket.h, fix names.
1335 * socket.c: renamed from fdsocket.c.
1336 remove _sys from procedure names.
1337 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
1338 add "socket" to features list.
1339 * net_db.c: renamed from socket.c.
1340 remove _sys from procedure names.
1341 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
1342 add "net-db" to features list.
1343 include "net_db.h". don't include <sys/socket.h> or
1346 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1348 * tags.h (scm_tags): Removed comma at end of last enumerator.
1350 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
1352 Don't use GCC extensions to allocate space for debugging frames.
1353 (Here he goes again! Why do we put up with this?!)
1354 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
1355 an scm_debug_info structure, not an in-line array of them. Add
1356 'info' member, to say how many vect elements we've used, for eval
1358 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
1359 a new variable debug_info_end to mark the end of vect, instead of
1360 the address of the 'info' pointer itself.
1361 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
1362 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
1363 (SCM_APPLY): Explicitly allocate space for debug.vect.
1364 * debug.c (scm_m_start_stack): Same, for vframe.vect.
1365 * stacks.c: Adjusted for new debug frame structure.
1366 (RELOC_INFO, RELOC_FRAME): New macros.
1367 (stack_depth, read_frames): Use them, and new scm_debug_frame
1368 element 'info', instead of magically knowing that eval frames have
1369 an info pointer sitting after vect.
1370 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
1372 (scm_init_stacks): Formatting tweaks.
1374 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
1376 Give GCC more control flow information, so it can be sure that
1377 variables aren't used uninitialized.
1378 * error.h (scm_error, scm_syserror, scm_syserror_msg,
1379 scm_sysmissing, scm_num_overflow, scm_out_of_range,
1380 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
1381 scm_misc_error): Tell GCC that these functions never return.
1382 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
1383 out the field type, call abort if SCM_ASSERT returns, to placate
1385 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
1386 scm_wta ever returns. We can't handle this case anyway, and this
1387 gives the optimizer more information.
1388 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
1389 scm_wta ever returns.
1391 In some cases, the code is fine, but GCC isn't smart enough to
1392 figure that out; this usually happens when one variable is only
1393 initialized and used when a particular condition holds true, and
1394 we know that condition will never change within a given invocation
1395 of the function. In this case, we simply initialize the variables
1396 to placate the compiler, hopefully to a value which will cause a
1397 crash if it is ever actually used.
1398 * print.c (scm_iprin1): Initialize mw_pos.
1399 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
1400 * throw.c (scm_ithrow): Initialize dynpair.
1401 * unif.c (scm_uniform_vector_ref): Initialize cra.
1402 * struct.c (init_struct): Initialize prot.
1403 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1405 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1406 if EXPR contains no expressions.
1408 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1410 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1411 cause an infinite loop (???). So much for the algebraic
1412 equivalency of variable-sized arrays and alloca...
1414 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1416 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1417 a SCM boolean, not a C boolean.
1419 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1421 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1422 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1423 rules for raising scm_mtrigger. Previously, unfortunate but not
1424 unlikely circumstances could result in almost constant invokation
1425 of the gc. Now, this situations should be less likely, but they
1426 are not prevented completely.
1428 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1430 * numbers.c (scm_fuck): Procedure removed; looks like old test
1432 * numbers.h: Prototype removed.
1434 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1436 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1437 array to a pointer, to match my Nov 21 change in eval.c.
1439 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1441 * libguile.h: Added #include "libguile/backtrace.h", #include
1442 "libguile/stacks.h".
1444 * strings.c (scm_string scm_make_string scm_string_ref
1445 scm_string_set_x scm_string_equal_p scm_string_append):
1446 Bugfix according to scm patch from Aubrey Jaffer:
1447 Corrected long-standing
1448 (not (eqv? (integer->char 128)
1449 (string-ref (make-string 1 (integer->char 128)) 0)))
1450 bug found by John Kozak <jk@noontide.demon.co.uk>.
1452 * strports.c, strports.h: Make scm_eval_0str return the value of
1453 the last expression evaluated (previously, it returned void).
1455 * strports.c, strports.h: New function: scm_read_0str. Does what
1458 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1460 * simpos.c (scm_getenv): return #f if string can't be found in the
1461 environment instead of throwing an exception, for compatibility
1462 with numerous other systems.
1464 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1466 * Makefile.am (.c.x): Use guile-snarf.
1467 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1469 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1471 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1473 * backtrace.c (scm_display_error_message): Made non-static, and
1474 renamed from display_error_message.
1475 * backtrace.h (scm_display_error_message): Added extern decl.
1476 * throw.c (uncaught_throw): Use it to display the error message.
1478 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1480 * inet_aton.c: Use #if 0, not #ifdef 0.
1482 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1484 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1485 to convert the returned value.
1486 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1487 the offset argument.
1489 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1491 Add new interface to catch/throw, usable from C as well as
1493 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1494 (scm_internal_catch): New function, replaces...
1495 (scm_catch_apply): Deleted.
1496 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1497 mechanism which is a bit more code, but can be used nicely from C
1498 and implement the Scheme semantics as well.
1499 (scm_internal_catch): This is the replacement; it's named after
1500 the analogous function in Emacs.
1501 (scm_catch): Reimplemented in terms of the above.
1502 (struct catch_body_data, catch_body, catch_handler): New
1503 functions, used by scm_catch.
1504 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1505 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1506 support for new cwdr.
1508 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1511 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1513 * acconfig.h: Added DYNAMIC_LINKING symbol.
1514 * configure.in: Add option and checks for dynamic linking.
1515 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1516 dynl.h: New files for dynamic linking support.
1517 * Makefile.am (libguile_a_SOURCES):
1519 (modinclude_HEADERS): Added "dynl.h".
1520 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1522 * init.c (scm_boot_guile_1): Call
1523 scm_init_dynamic_linking to initialize dynamic linking support.
1525 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1527 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1528 (as we Schemers say). It needs to be global, so that I can tweak
1529 it for the proper operation of unexec.
1530 (scm_boot_guile_1_live): New variable, see above.
1532 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1534 * guile-snarf.sh: Removed.
1535 * PLUGIN/guile.libs: Added dependency for -lm.
1536 * acinclude.m4: Renamed from aclocal.m4.
1537 * PLUGIN/greet: Removed.
1538 * Makefile.am, aclocal.m4: New files.
1539 * configure.in: Updated for Automake.
1541 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1543 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1544 and not top_level_lookup_thunk_var.
1546 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1548 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1550 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1552 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1553 Scheme function, instead of syntax. Single argument is now a
1556 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1558 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1559 scm_ra_divide): Properly terminate statements passed as arguments
1560 to IVDEP macros. (Thanks to Bernard Urban.)
1562 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1563 with non-constant sizes. (Thanks to Bernard Urban.)
1565 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1567 It's an "eval closure", not an "eval thunk." A thunk is a
1568 function of no arguments.
1569 * root.h (struct scm_root_state): Renamed
1570 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1571 (scm_top_level_lookup_closure_var): Renamed from
1572 scm_top_level_lookup_thunk_var.
1573 * root.c (mark_root): Uses changed.
1574 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1575 * init.c (scm_start_stack): Uses changed.
1576 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1577 Change scheme-visible name to *top-level-lookup-closure* from
1578 *top-level-lookup-thunk*.
1580 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1582 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1583 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1585 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1587 * gc.c (struct scm_heap_seg_data): Doc fixes.
1589 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1590 sweeping. Then, prepend each segment's free cells to its
1591 freelist, rather than wiping out the old value. (Thanks to Marius
1594 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1595 scm_check_freelist, scm_debug_newcell): New functions and
1596 variables, for debugging freelist problems.
1597 * pairs.h (SCM_NEWCELL): New debugging version added.
1598 * gc.h (scm_debug_newcell): Added extern declaration, used by
1599 debugging version of SCM_NEWCELL.
1601 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1603 On some systems <libc.h> conflicts with <unistd.h>, and should not
1604 be #included at all.
1605 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1606 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1607 * configure.in: Call it.
1608 * posix.c, filesys.c: Use its results to decide whether or not to
1610 * configure, scmconfig.h.in: Rebuilt with autoconf and
1613 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1615 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1616 pointer to the stdio stream before calling scm_setbuf0, so the
1617 latter will be able to retrieve it. I'm surprised this didn't
1618 segfault earlier. (Thanks to Christopher Lee.)
1620 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1622 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1625 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1627 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1628 number of stack narrowing specifier pairs. The first specifier in
1629 a pair controls inner border, the second the outer border. A
1630 number means cut that number of frames, a procedure object means
1631 cut until that object is found in operator position in a frame.
1633 * root.c (cwdr): Bugfix.
1635 * read.c: Recording of positions disabled by default.
1637 * procs.c (scm_closure_p): New function.
1639 * posix.c (scm_tmpnam): New function.
1641 * load.c: Added #include "throw.h".
1642 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1645 * load.c, load.h (scm_read_and_eval_x): New function.
1647 * eval.c: Renamed debug option "deval" to "debug".
1649 (scm_eval_x): `eval!' is no longer accessible from the scheme
1650 level. Motivation: We can't allow operations which introduce
1651 glocs into the scheme level. Guile's type system can't handle
1652 these as data. Use `eval' or `read-and-eval!' as replacement.
1654 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1655 SCM_CONSP since this is a macro!; Set vframe.prev to
1656 scm_last_debug_frame instead of 0. In this way we can look
1657 "above" the virtual start stack frame if we wish.
1658 (scm_debug_hang): New function: Useful for debugging Guile in
1659 certain tricky situations. Will probably be removed later...
1661 * debug.h: Changed semantics of debug option "backtrace". This
1662 option now only indicates whether we want automatic backtrace at
1665 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1667 * ports.c: #include "filesys.h"
1668 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1670 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1671 Motivation: This is system specific code which is related to file
1672 I/O. It also may use select. Added code by Gary Houston to
1673 detect presence of character in stdio buffers.
1675 * libguile.h: #include "libguile/libpath.h"
1677 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1678 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1679 SCM_SITE_DIR; Install libpath.h among the other include files.
1681 * load.c, load.h (scm_sys_package_data_dir): New function.
1683 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1685 * stacks.h: Bugfix: Don't use tail-array length field as stack
1686 length field! This screwed GC.
1688 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1690 * _scm.h: Added #ifndef around definition of macros min and max.
1692 * __scm.h: Added hooks for threads to plugin to in ints protection
1693 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1694 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1695 the main code in these macros duplicated and spread over multiple
1696 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1697 SCM_THREAD_SWITCHING_CODE.
1699 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1701 * snarf.h: New file.
1702 * guile-snarf.sh: New file.
1703 * Makefile.in (inner_h_files): Added snarf.h
1704 (ancillary, install, uninstall, distclean): Added actions for
1706 (.c.x): Use guile-snarf.
1707 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1708 (gen_c_files): Note that these depend on guile-snarf.
1709 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1710 now in "snarf.h". Added #include "snarf.h" to get them.
1711 * libguile.h: Added #include "snarf.h".
1712 (Patches applied and tweaked by Jim Blandy.)
1714 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1716 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1717 standards suggest against providing prototypes for system
1718 functions. Thanks to Greg Troxel.
1720 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1722 * strports.c (scm_eval_0str): New function.
1723 #include "read.h", to get prototype for scm_read.
1724 * Makefile.in (strports.o): Update dependencies.
1725 * strports.h: New prototype.
1727 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1728 scheme name from "int?" to "integer?". It seems to do the job.
1729 * numbers.h: Rename prototype too.
1730 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1733 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1734 scm_num_eq_p): Rename these according to R4RS conventions: call
1735 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1736 to making libguile R4RS compliant without ice-9...
1738 * load.c (scm_sys_search_load_path): Search for files under all
1739 extensions listed in the %load-extensions variable. If FILENAME
1740 is absolute, return it unchanged, without searching the load path.
1741 (scm_loc_load_extensions): New variable, pointing to
1742 %load-extensions' value cell.
1743 (scm_init_load): Initialize it, and the value it points to.
1744 (scm_primitive_load_path): Improve error reporting.
1746 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1747 of new Scheme variable %load-hook.
1748 (scm_primitive_load): Apply %load-hook to filename.
1750 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1752 * configure.in: add tests for figuring out whether buffered data
1753 is available in a FILE structure, which is needed by char-ready.
1755 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1758 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1759 exceptions using misc_error instead of syserror. It seems a bit
1760 odd to throw an exception if a string can't be found in the
1761 environment, but it's consistent with open-file, stat etc.
1762 (simpos.h): remove sys_ from getenv.
1764 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1765 occurs, throw an error instead of returning errno. Return value
1767 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1769 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1771 * filesys.c (scm_stat2scm): derive file type and permissions from
1772 the stat mode and append them to the returned vector.
1773 There isn't much overhead in doing this and it avoids the need to
1774 work with S_IRUSR et al. in Scheme.
1775 Define symbols scm_sym_regular etc.
1776 (scm_init_filesys): don't intern S_IRUSR etc.
1778 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1779 and s_primitive_load_path.
1781 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1783 * error.h: don't declare error symbols. prototype for scm_misc_error.
1785 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1788 * error.c: use SCM_SYMBOL to set up error keys.
1789 scm_misc_error: new procedure.
1791 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1793 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1794 between `#!' and `!#' is ignored.
1795 (skip_scsh_block_comment): New function.
1797 * feature.c (scm_set_program_arguments): New argument, FIRST.
1798 * feature.h: Update prototype.
1799 * init.c (scm_boot_guile_1): Pass new argument to
1800 scm_set_program_arguments.
1802 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1804 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1805 (scm_boot_guile): Call scm_set_program_arguments here, later than
1806 the old initialization.
1808 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1809 initialization procedure.
1810 - Delete in, out, err arguments; there are other perfectly good
1811 ways to override these when desired.
1812 - Delete result argument; this function shouldn't ever return.
1813 - Rename init_func argument to main_func, for less confusion.
1814 - Delete boot_cmd argument; main_func is more general.
1815 -Add 'closure' argument, to help people pass data to main_func
1816 without resorting to global variables.
1817 - Abort if reentered; don't bother returning an error code.
1818 - Call scm_init_standard_ports to set up the default/current
1819 standard ports; no need to pass them to scm_start_stack.
1820 - Remove code to evaluate the boot_cmd, and start the repl; let
1821 the user do something like that in main_func if they want.
1822 - Remove code to package up a return value; main_func can do any
1824 - Call exit (0), instead of returning.
1825 (scm_start_stack): Don't initialize the I/O ports here; that's
1826 weird. Delete in, out, err arguments. Move guts to
1827 scm_init_standard_ports, scm_stdio_to_port.
1828 (scm_init_standard_ports): New function, to set up current and
1829 default standard ports.
1830 (scm_start_stack, scm_restart_stack): Make these static.
1831 * init.h (scm_boot_guile): Adjust declaration.
1832 (scm_start_stack, scm_restart_stack): Remove externally
1833 visible declarations for these.
1834 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1836 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1837 written out several times in scm_start_stack.
1838 * fports.h: New declaration for the above.
1840 * feature.c (scm_set_program_arguments): New function.
1841 * feature.h: New declaration for the above.
1843 * ports.c: Formatting tweak.
1845 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1847 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1848 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1849 for obtaining the address of a car or cdr field. Motivation:
1850 &SCM_CXR make assumptions about the internal structure of the
1853 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1854 Motivation: see SCM_CXRLOC.
1856 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1857 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1858 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1859 Motivation: Safer use. Some other macros are defined in terms of
1860 these operations. If these are defined using the SCM_SETCXR
1861 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1862 to inefficiency and an <e1> with side-effects could potentially
1863 break. Also, these particular operations are heavily utilized in
1864 the garbage collector. In unoptimized code there will be a
1867 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1868 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1869 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1870 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1871 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1872 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1873 vports.c: Cleaned up use of pairs: Don't make any special
1874 assumptions about the internal structure of selectors and
1875 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1876 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1877 (Among other things, this change makes it easier to build Guile
1878 with certain compilers which have problems with casted lvalues.)
1880 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1882 * stacks.c: Improve selection of relevant stack frames when making
1883 a stack object. Introduce one level of indirection in the stack
1884 object to make it possible to "narrow" to a certain region of the
1885 stack. This facilitates making use of more clever algorithms (not
1886 implemented) for selecting relevant frames and gives a cleaner
1887 design since selection of frames can be done independently of
1888 extraction of frames from the real stack.
1889 (scm_stack_id): Also take #t as argument which means look at
1892 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1893 Turn n_tail into an integer directly representing current number
1894 of frames in stack. Add field tail.
1896 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1898 * debug.c (scm_make_memoized): Made it available at scheme level.
1899 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1900 SCM_NIMP before applying heavier predicates in argument checking.
1901 (scm_local_eval): Also take memoized object as argument.
1903 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1904 aren't created with zero length, but should such a strange
1905 creature suddenly turn up...
1907 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1909 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1910 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1912 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1914 * variable.c (scm_make_variable): Make the name hint optional, as
1916 (anonymous_variable_sym): Renamed from variable_sym. All uses
1919 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1920 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1921 of scm_primitive_load_path was also changed to
1922 "primitive-load-path", from "%try-load-path". Callers changed.
1923 We'd like to respect the convention that a function named
1924 "try-mumble" should behave just like the function called "mumble",
1925 but return #f instead of signalling some error.
1926 * load.h: Rename prototypes.
1928 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1930 * print.c (make_print_state, grow_print_state), print.h: Modified
1931 the print state representation: Don't use a tail array for
1932 recording of circular references. Resizing of the print state
1933 structure invalidates the print state pointer. To avoid passing
1934 around an indirect print state reference to all printing
1935 functions, we instead let the print state reference a resizable
1938 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1940 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1941 Don't crash when passed an improper list terminated by a
1942 non-immediate value.
1944 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1946 Allocate data for structures on an eight-byte boundary, as
1947 required by the tagging system.
1948 * struct.c (alloc_struct): New function.
1949 (scm_make_struct, scm_make_vtable_vtable): Call it.
1950 * struct.h (scm_struct_n_extra_words): Bump to 3.
1951 (scm_struct_i_ptr): New "field".
1952 * gc.c (scm_gc_sweep): When we need to free the data, use the
1953 information stored by alloc_struct to find the beginning of the
1954 block allocated to the structure, so we can free it.
1956 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1958 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1961 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1962 (scm_debug_info): New member: id.
1964 * stacks.c: Stacks are now represented as structs; Stacks have an
1965 id given to them by `start-stack'.
1966 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1968 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1969 Changed stack representation.
1971 * debug.c (scm_procedure_name): Try procedure property `name' for
1972 compiled closures aswell.
1974 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1976 * eval.c: scm_i_name moved to gsubr.c

1978 objects. (Earlier, only closures were recorded.)
1980 * procprop.h: Added declaration of scm_i_name.
1982 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1983 (scm_make_gsubr): Record names of compiled closures.
1985 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1987 * debug.c, debug.h: Removed obsolete code.
1989 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1990 stacks.c: Renamed regs --> scm_contregs.
1992 * print.c (scm_free_print_state): Cleanup print state before
1993 returning it to pool. It is better to do it here than in
1994 scm_prin1 since scm_prin1 is called often.
1996 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1997 s_set_source_property_x): Check that first argument is a pair or a
2000 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
2001 scm_i_line, scm_i_column and scm_i_breakpoint global.
2003 * init.c: Added #include "backtrace.h" and #include "stacks.h".

2014 backtrace.h, stacks.c and stacks.h.
2016 * symbols.c (scm_sym2ovcell): Fixed documentation.
2018 * _scm.h (min, max): Added.
2020 * async.c: Moved `min' macro to _scm.h.
2022 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
2023 SCM_BACKTRACE_INDENT.
2025 * eval.c: Added new debug options `maxdepth' and `indent'.
2027 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
2029 * print.h: Added selector SCM_PRINT_STATE.
2031 * print.c: New functions: scm_make_print_state,
2032 scm_free_print_state.
2034 * print.h: Added declarations for scm_make_print_state,
2035 scm_free_print_state.
2037 * debug.c (scm_m_start_stack): New acro.
2039 * debug.h: Small cleanup.
2041 * init.c (scm_boot_guile_1): Moved scm_init_debug below

2064 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
2065 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
2066 declare functions with prototypes. (Patch thanks to Marius
2069 More prototype-related changes from Marius Vollmer:
2070 * gdb_interface.h: Wrapped header file in #ifdef/#endif
2071 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
2072 * ports.h (ptobfuns): Added prototypes. This means some casting in
2074 * fports.c: Added casts for initializations, since the functions
2075 are defined to take FILE * as their stream argument, not SCM.
2076 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
2077 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
2078 to `char *str_data' to conform to prototype.
2080 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2082 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
2084 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
2086 * stime.c, stime.h: use SCM_P method.
2088 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2090 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
2091 be given at least two arguments. Insist that lst's last element
2092 be a list, but don't make any requirements of its predecessors.
2094 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2096 * eval.c (scm_nconc2last): Revert last change; there seems to be
2097 other stuff going on here.
2099 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2101 * eval.c (scm_nconc2last): Make sure that each element of lst
2102 (which is a list of argument lists, except for the tail) is a
2103 proper list, i.e., finite and terminated by '().
2105 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2107 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
2110 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
2111 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
2114 * vectors.c (scm_make_vector): Fill vectors with the undefined
2115 value, to help make Guile Scheme code more portable to other
2118 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
2119 * symbols.h, tags.h: Doc fixes.
2121 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
2123 * async.c (scm_take_signal): Doc fixes.
2125 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
2127 * numbers.c (scm_divbigint): When the remainder is zero, we don't
2128 want to subtract it from the modulus; we just want to leave it
2131 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
2133 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
2136 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
2138 * throw.c (scm_catch_apply): Finished implementation of
2141 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2143 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
2145 (scm_init_filesys): set "i/o-extensions" feature.
2148 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
2150 * Makefile.in (root.o): Correct dependencies.
2152 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
2154 * Makefile.in: Added dependency entry for root.o.
2156 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
2157 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
2159 * init.c (scm_start_stack): Set initial root continuation number
2162 * procs.c: New function: scm_thunk_p.
2164 * procs.h: Added declarations of scm_thunk_p.
2166 * root.c: Renamed `call-with-new-root' -->
2167 `call-with-dynamic-root'.
2168 (cwdr): Removed allocation of new root state. This should be done
2169 separately by use of scm_make_root.
2170 (scm_apply_with_dynamic_root): New function: Does what it
2171 sounds like. Needed when spawning threads.
2173 * root.h: Added member last_debug_frame to root state.
2174 Added #include "libguile/debug.h"
2176 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
2177 arguments. The motivation is that code in root.c needs catch
2178 functionality, and we want to avoid code duplication.
2179 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2180 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2181 handlers that run without popping the stack into the dynwind
2184 * throw.h: Added prototypes for scm_catch_apply and
2187 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2189 * root.h (scm_root, scm_set_root): Decouple thread support details
2190 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2191 SCM_SET_THREAD_LOCAL_DATA.
2193 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2194 and tortoise scanning loop.
2196 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2198 * Makefile.in: Rebuild dependencies.
2200 * libguile.h: #include "libguile/print.h" before "smob.h", since
2201 the latter uses the print_state structure.
2203 * throw.c (scm_ithrow): Use the correct variable when checking to
2204 see if a given element of scm_dynwinds is a valid catch.
2206 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2207 structure, abort; don't just silently ignore the garbage.
2209 * _scm.h: #include "print.h" here, since it seems to be used just
2211 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2212 strports.c, unif.h: Don't #include "print.h".
2214 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2216 * feature.h (scm_loc_features): Removed external declaration.
2217 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2219 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2221 * feature.c (scm_init_feature): Added threads feature (needs to be
2222 initialized here, since features doesn't exist when
2223 scm_init_threads is called).
2225 * libguile.h: Added #include "libguile/../threads/threads.h".
2226 (This is a kludge to get thread support working. This should be
2229 * configure.in, acconfig.h: Added flags for thread support.
2231 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2234 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2235 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2238 * _scm.h: Added conditional #include "threads.h"
2240 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2241 SCM_THREADS_SWITCHING_CODE.
2243 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2244 allocate the basic dynamic root object.
2245 (scm_boot_guile): Added call to scm_init_root.
2247 * root.c, root.h: Added root smob.
2248 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2249 functions: Implements dynamic roots mostly according to spec in
2250 SCM manual. Main difference is that the second argument is a
2251 throw handler rather than an error "thunk".
2253 * root.h: Added declaration of scm_init_root.
2255 * root.c: Added #include "genio.h", #include "smob.h", #include
2256 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2258 (scm_init_root): Added #include "root.x".
2260 * throw.c: Added #include "stackchk.h"
2261 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2262 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2263 can be used in scm_call_with_new_root; Added reenabling of stack
2264 checking when catching a throw.
2266 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2268 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2270 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2271 element is not found, as per R4RS.
2273 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2275 * list.c: Doc fixes throughout.
2277 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2279 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2280 declare the char * to be const. Avoids a warning in rgx.c.
2282 * ports.h: spelling fix.
2284 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2287 * load.c (scm_sys_try_load_path): throw an error if file not found
2288 (like it says it in NEWS).
2290 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2292 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2293 PROPS slot to '(), not #f; it's an empty alist.
2295 * throw.h, throw.c: Use SCM_P instead of #if hair.
2297 Remove special support for uncaught throws; see throw.c for
2299 * throw.c (uncaught_throw): New function.
2300 (scm_ithrow): Call uncaught_throw if we don't find a throw
2301 target; don't mess with scm_bad_throw_vcell.
2302 (scm_bad_throw_vcell): Variable deleted.
2303 (scm_init_throw): Don't initialize it.
2305 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2308 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2310 * numbers.c (scm_istr2int): If the number is short (as most
2311 numbers are), just call scm_small_istr2int to deal with it.
2312 (scm_small_istr2int): New function, created by un-#ifdefing the
2313 non-bignum version of scm_istr2int and renaming it.
2315 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2317 * load.c (scm_sys_try_load): don't check whether value returned
2318 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2319 Change the Scheme name from %try-load to primitive-load.
2321 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2322 Can avoid passing a message, allowing it to be derived in the
2323 error handler (e.g., if we want to throw to the key both from
2326 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2328 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2329 references now have a new appearance which is more compact and
2330 also gives a clue about what the target of the reference is.
2331 By setting parameters in the print state, more fancy printing can
2332 be achieved. This is used by the (not yet commited) backtrace
2335 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2337 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2340 * print.c: Added #include "struct.h". Removed function
2343 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2344 scm_iprin1. Removed prototype for scm_prlist.
2346 * arbiters.c (prinarb),
2347 async.c (print_async),
2348 debug.c (prindebugobj, prinmemoized),
2349 eval.c (prinprom, prinmacro),
2350 filesys.c (scm_fd_print, scm_dir_print),
2352 mallocs.c (prinmalloc),
2353 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2354 smob.h (scm_smobfuns),
2355 srcprop.c (prinsrcprops),
2357 unif.c, unif.h (scm_raprin1, rapr1),
2358 variable.c (prin_var): Changed argument `int writing' to
2359 `scm_print_state *pstate'.
2361 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2362 that it will be called before scm_init_print.
2364 * print.c (scm_prin1): Print states are now allocated when calling
2365 scm_prin1 and then passed around to all printing functions as an
2366 argument. A cache `print_state_pool' enables reuse of print
2368 (scm_make_print_state): New function.
2369 (scm_iprin1): Adaption to print states.
2370 (scm_iprlist): An initial "hare and tortoise" scan brings down
2371 time complexity to O (depth * N). (Better time complexity will be
2372 achieved when the printing code is completely rewritten.)
2374 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2376 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
2377 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
2378 it gets done whether or not the cache variable has a value.
2380 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2382 Distinguish #f and ().
2383 * __scm.h: #undef SICP.
2384 * pairs.h (SCM_EOL): Delete this definition, equating it with
2386 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2387 the value it used to have. Doc fixes, too.
2389 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2391 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2392 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2393 Lord's implementation of structs, allowing for tail arrays as
2394 described in the manual. Also fixed some bugs. (Both the interface
2395 and the implementation should be improved.)
2397 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2399 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2400 People who whish to see the source can do `(print-enable 'source)'.
2401 Removed #ifdef DEBUG_EXTENSIONS.
2403 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2405 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2406 integer (assuming for now accepting an integer is a good thing).
2408 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2409 %S will be used instead for write'ing arguments.
2411 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2412 asserts. fix a few other asserts.
2413 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2414 scm_uniform_vector_ref, scm_array_set_x,
2415 scm_dimensions_to_unform_array): change args in
2416 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2417 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2418 scm_substring_fill_x): likewise.
2419 gsubr.c (scm_gsubr_apply): likewise.
2420 eval.c (SCM_APPLY): likewise.
2422 * eval.c (4 places): replace scm_everr with lgh_error or
2425 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2426 scm_memory_error): new procedures.
2427 scm_everr: deleted. can use scm_wta, dropping first two args.
2428 scm_error: convert NULL subr to SCM_BOOL_F.
2430 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2433 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2436 * error.c, error.h: new error keys: scm_arg_type_key,
2437 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2439 scm_wta: reimplement using lgh_error instead of scm_everr.
2441 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2443 * gdbint.c: scm_lread now has one more argument.
2445 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2446 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2447 loading source from non-file ports, which, e. g., happens when
2448 using the Emacs interface).
2450 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2453 * read.c: Added code for recording of positions of source code
2454 expressions; New functions: recsexpr, scm_lreadrecparen;
2455 _scm_make_srcprops --> scm_make_srcprops
2456 (scm_flush_ws): Removed updating of positions counters. This work
2457 is already done by scm_gen_getc
2459 * read.h: Added prototype for scm_lreadrecparen
2461 * print.c: Added #include "alist.h"
2463 * eval.c: Added #include "hash.h"

2470 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2471 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2472 --> scm_make_srcprops
2474 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2475 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2476 function calls in the definition of the whash access macros.
2478 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2480 * init.c (scm_boot_guile): Add level of indirection to
2481 scm_boot_guile_1() to ensure that stack base pointer is properly
2482 initialized. There was no guarantee that variable i was the
2483 highest/lowest variable on stack (i.e. the call frame of
2484 scm_boot_guile was not completely protected from gc).
2486 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2488 * ports.h (scm_port_table): put back file_name, it will be used to
2489 support debugging. Undo related changes in fports.c, ioext.c,
2492 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2494 * ports.h (scm_port_table): remove file_name member for now, it seems
2496 * fports.c (scm_open_file): don't set file_name in PTAB.
2497 (prinfport): don't use file_name in PTAB.
2498 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2499 * ports.c (scm_add_to_port_table): don't intialize file_name.
2500 (scm_port_file_name): remove for now.
2501 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2503 * fports.h (scm_mkfile): prototype deleted.
2504 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2506 * debug.c, unif.c: use scm_out_of_range instead of
2507 wta for range errors (ASSERT still needs work).
2509 * error.c, error.h (scm_out_of_range): new procedure.
2511 * error.c, error.h (scm_out_of_range_key): new key.
2513 * posix.c (scm_sync): #else was missing.
2515 * error.c, error.h: append _key to names scm_num_overflow and
2518 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2519 of consing an empty list.
2520 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2521 of macros, saves code and string space.
2522 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2523 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2524 lower case. Rename scm_syserror_m to scm_syserror_msg.
2525 error.h: prototypes for new procedures.
2527 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2529 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2531 * error.c, error.h: setup scm_num_overflow key.
2533 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2534 Remove definition of SCM_OVSCM_FLOW.
2536 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2538 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2539 explicit message and args.
2541 * error.c, error.h, __scm.h: change system_error_sym to
2544 * error.c (system_error_sym): remove leading %% from the Scheme name
2547 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2549 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2551 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2552 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2553 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2554 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2555 renamed. (These were introduced by unsupervised name
2558 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2560 * print.c: Added code for detection of circular references during
2561 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2562 a hook for printing of closures (accessible via print options).
2563 This leads to a split of calls to scm_iprin1 into two classes:
2564 elementary print operations (e. g. the code which prints a smob)
2565 still use scm_iprin1 while top level calls (like scm_display) use
2566 scm_prin1. scm_prin1 begins by clearing the data structure used
2567 to record reference information.
2569 * print.h: Added declarations of scm_prin1 and scm_prlist.
2571 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2573 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2575 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2577 * error.c (err_head): scm_iprin1 --> scm_prin1
2579 * debug.c: Adjusted header comment.
2583 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2585 * strerror.c: Doc fix.
2587 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2589 * gdbint.c (gdb_read): Now possible to run during GC.
2590 (unmark_port, remark_port): New functions.
2592 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2594 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2595 of allocating a new string object. Also, increase size by
2596 the factor 2 instead of 1.5.
2598 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2600 * __scm.h (SCM_P): Corrected to run under traditional C.
2602 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2605 * async.c: Calls to scm_sysintern corrected.
2607 * async.h (scm_async_clock): Redundant declaration removed.
2609 * continuations.c (scm_dynthrow): Redundant declaration removed.
2611 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2612 Definition typos corrected.
2614 * debug.h: Missing declarations of functions in debug.c added
2617 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2618 Missing declarations to functions in eval.c added.
2620 * filesys.c: Possibly uninitialized variable rv.
2622 * gc.h (scm_object_addr, scm_unhash_name): Missing
2623 declarations of functions defined in gc.c added.
2625 * genio.c: Possible typos str_data -> wstr_data. ???
2627 * genio.c: Possibly unintended shadowing of local variable
2628 `int c' (gotos out of scope of inner `c'). ???
2630 * init.c: Uninitialized `SCM last' may be used.
2632 * ioext.h: (scm_sys_isatty_p): Typo.
2634 * list.h (scm_list_head): Missing prototype for function in
2637 * numbers.c (scm_two_doubles): Changed from extern to static
2638 (is used only within numbers.c).
2640 * numbers.h: Repeated declarations removed.
2642 * ports.h (scm_close_all_ports_except): Declaration for the
2643 function defined in ports.c added.
2645 * posix.h: Missing declarations added.
2647 * procs.h (scm_make_subr_opt): Missing declaration added.
2649 * socket.h (scm_sys_gethost): Missing declaration added.
2651 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2653 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2654 Missing declarations added.
2656 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2658 * struct.c: Uninitialized variable `SCM answer' may be used.
2660 * unif.c (l2ra): Declaration prototype.
2662 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2663 defined in ramap.c).
2665 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2666 Redundant declarations removed (they are in ramap.h).
2668 * variable.h (scm_make_udvariable,
2669 scm_make_undefined_variable): Declaration corrected to
2670 correspond variable.c.
2672 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2673 Missing declarations added.
2675 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2677 * Makefile.in (distclean): Don't forget to delete fd.h.
2679 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2681 * fd.h.in, tags.h: Trivial cleanups.
2683 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2684 marksweep.h just declared functions from gc.c.
2685 * gc.h, libguile.h: Don't #include "marksweep.h".
2686 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2687 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2688 dependencies updated.
2690 * libguile.h: Don't #include "files.h"; it's been deleted.
2692 * files.c (scm_sys_delete_file): Moved to filesys.c.
2693 File is now empty; deleted.
2695 * filesys.c: scm_sys_delete_file is now here. Remove
2696 #if's; they seem to rely on remnants of an old portability
2697 regimen. If the problems come up again, solve them properly,
2698 using autoconf. Specifically: Don't test M_SYSV, and #define
2699 remove to be unlink if it's #defined; don't use remove just
2700 because HAVE_STDC_HEADERS is #defined.
2701 * filesys.h: Add declarations for scm_sys_delete_file.
2702 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2703 files.o, files.h, files.c, and files.x.
2704 * init.c: Don't #include "files.h", and don't call scm_init_files.
2706 Use SCM_P instead of PROTO; the latter intrudes on the user's
2708 * params.h: Deleted; definition of SCM_P moved to...
2709 * __scm.h: ... here, where it replaces PROTO macro.
2710 * libguile.h, smob.h: Don't #include "params.h".
2711 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2712 smob.h: Fix prototypes accordingly.
2713 * Makefile.in: Update dependencies.
2714 (inner_h_files): Remove params.h.
2716 * gc.c: #include "gc.h"; every module should include its header,
2717 to let the compiler cross-check the declarations against the
2720 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2721 simpos.h: #include "libguile/__scm.h".
2723 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2725 * init.c: Don't forget to #include smob.h and init.h.
2726 * Makefile.in: Dependencies updated.
2728 * smob.h: Use PROTO instead of #if __STDC__.
2730 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2732 * __scm.h: Doc fixes.
2734 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2735 <angles>; this allows `make depends' to work properly.
2737 * libguile.h: #include smob.h and pairs.h before the others; they
2738 define typedefs used by other headers.
2740 C files should #include only the header files they need, not
2741 libguile.h (which #includes all the header files); the pointless
2742 recompilation was wasting my time.
2743 * Makefile.in (all .o dependency lists): Regenerated.
2744 * libguile.h: Don't try to get a definition for size_t here...
2745 * __scm.h: Do it here.
2746 * _scm.h: Since this is the internal libguile header, put things
2747 here that all (or a majority) of the libguile files will want.
2748 Don't #include <libguile.h> here; that generates dependencies on
2749 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2750 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2751 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2852 * print.h, read.h: #include "options.h", since everyone who uses
2853 either of these files will need that.
2855 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2856 anyone who uses this file will need them to define the smob
2857 printing functions. Also, get markers.h, since people will need
2858 to #define the mark functions.
2860 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...

2870 parse this; don't bother #including "ports.h", since print.h gets
2873 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2875 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2876 this; it's now a reference to an element of *scm_root.
2878 * debug.h: Don't #include "options.h"; the compiler won't be able
2879 to find that once the headers are installed; instead, #include
2880 "libguile/options.h".
2881 * gc.h: Same, with marksweep.h.
2882 * mbstrings.h: Same, with symbols.h.
2883 * scmhob.h: Same, with _scm.h.
2884 * smob.h: Same, with params.h.
2886 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2887 C files; there's no need for this, and it forces recompilations
2890 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2892 * error.c (scm_error): declare scm_error_callback.
2894 * error.h: prototype for scm_error_callback.
2896 * __scm.h: define lgh_error.
2897 (SCM_SYSERROR): redefine using lgh_error.
2899 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2901 * error.c (scm_error): new procedure.
2903 * error.h: prototype for scm_error.
2905 * Makefile.in (install): install scmconfig.h from the current
2906 directory, not $(srcdir).
2908 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2910 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2911 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2912 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2913 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
2914 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
2915 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2916 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2917 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2918 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2919 vports.h, weaks.h: #include "libguile/__scm.h", not
2920 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2921 dependencies are within libguile properly.
2923 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2925 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2926 when scmconfig.h doesn't exist.
2928 * load.c (scm_sys_try_load): Correct spelling.
2930 * feature.c (scm_loc_features): Make this static.
2932 * Makefile.in (libpath.h): Omit trailing slash from path. We
2933 shouldn't require it of users, so why put it here?
2935 Move code to initialize and search %load-path from ice-9 to C
2936 code, so we can use the load-path to find the ice-9 boot code;
2937 this makes it easier to run Guile without installing it. See
2938 corresponding changes in guile/Makefile.in.
2939 * feature.c: Move stuff concerned with the load path to load.c.
2940 (scm_compiled_library_path): Deleted.
2941 Don't #include libpath.h here.
2942 * feature.h: Don't mention scm_compiled_library_path.
2943 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2944 <sys/stat.h>, and <unistd.h> (if present).
2945 (R_OK): #define if the system hasn't deigned to.
2946 (scm_loc_load_path): New variable.
2947 (scm_init_load_path, scm_sys_search_load_path,
2948 scm_sys_try_load_path): New functions.
2949 (scm_init_load): Initialize scm_loc_load_path to point to the
2950 value cell of the Scheme %load-path variable.
2951 * load.h: Add declarations for scm_sys_search_load_path,
2952 scm_sys_try_load_path.
2953 * init.c: Call scm_init_load_path.
2954 * Makefile.in (feature.o, load.o): Dependencies updated.
2956 * load.c, load.h: Rewrite using PROTO macro.
2958 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2960 * gc.c (scm_cellp): New function: C predicate to determine if an
2961 SCM value can be regarded as a pointer to a cell on the heap.
2963 * gc.h: Added declaration of scm_cellp.
2965 * gdb_interface.h: New file: The GDB interface header from the GDB
2968 * gdbint.c: New file: GDB interface.
2970 * gdbint.h: New file: GDB interface.
2972 * libguile.h: Added #include <libguile/gdbint.h>.
2974 * init.c (scm_boot_guile): Added scm_init_gdbint.
2976 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2977 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2978 found if object files and source are kept separate).
2980 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2982 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2984 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2986 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2987 TK_SRC_DIR; they're not relevant any more.
2989 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2990 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2992 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2994 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2995 search path, so we can find the <libguile/MUMBLE.h> headers.
2997 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2999 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
3000 implicit in the .c.o rule.
3001 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
3004 Put the library path in a header file, instead of passing it on
3005 the command line in every compilation.
3006 * Makefile.in (libpath.h): New target.
3007 (feature.o): Depend on libpath.h.
3008 (clean): Delete libpath.h.
3009 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
3010 * feature.c: ... #include "libpath.h" here.
3011 * .cvsignore: Ignore libpath.h.
3013 Don't install the unwashed masses of Guile header files in the
3014 main #include path; put most of them in a subdirectory called
3015 'libguile'. This avoids naming conflicts between Guile header
3016 files and system header files (of which there were a few).
3017 * Makefile.in (pkgincludedir): Deleted.
3018 (innerincludedir): New variable; this and $(includedir) are enough.
3019 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
3020 (installed_h_files): Divide this up. Now this variable lists
3021 those header files which should go into $(includedir) (i.e. appear
3022 directly in the #include path), and ...
3023 (inner_h_files): ... this new variable says which files appear in
3024 a subdirectory, and are referred to as <libguile/mumble.h>.
3025 (h_files): List them both.
3026 (install): Create innerincludedir, not pkgincludedir. Put
3027 the installed_h_files and inner_h_files in their proper places.
3028 (uninstall): Corresponding changes.
3029 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3030 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3031 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
3032 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
3033 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
3034 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3035 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3036 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3037 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3038 vports.h, weaks.h: Find __scm.h in its new location.
3039 * __scm.h: Find scmconfig.h and tags.h in their new locations
3040 (they're both "inner" files).
3042 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
3044 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
3046 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3048 * posix.c: Doc fixes.
3050 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
3052 * socket.c: Don't include a prototype for inet_aton; just use a
3053 K&R style declaration, to avoid warnings but minimize the chance
3054 of conflicts with the system.
3056 On NextStep, <utime.h> doesn't define struct utime, unless we
3057 #define _POSIX_SOURCE before #including it.
3058 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
3059 * acconfig.h: New comment text for above CPP symbol.
3060 * configure.in: Call it.
3061 * posix.c: #define _POSIX_SOURCE if it seems necessary.
3063 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
3065 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
3066 testing for __EMX__.
3068 * posix.c: #include <libc.h>, if it exists.
3070 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
3071 don't even know if the latter exists.
3073 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
3074 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
3075 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
3077 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
3079 (scm_init_posix): Use them when initializing the Scheme constants
3082 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3084 * Makefile.in (libdir, includedir, bindir): Use the
3085 autoconf-supplied values, instead of deriving them ourselves.
3086 (pkgincludedir, datadir, pkgdatadir): New variables.
3087 (install, uninstall): Put the header files in a special
3088 subdirectory, not in the main search path.
3090 * Makefile.in (ALL_CFLAGS): Provide the proper value for
3091 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
3093 * Makefile.in (IMPLPATH): Deleted; never used.
3095 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
3096 on the Tcl/Tk source any more.
3097 (INCLUDE_CFLAGS): Remove references to the above.
3099 * Makefile.in (version.o): Corrected dependencies.
3101 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
3103 * libguile.h: #include "version.h"
3105 * init.c (scm_boot_guile): Call scm_init_version.
3106 * gscm.c (gscm_run_scm): Call scm_init_version.
3108 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
3109 GUILE_VERSION): AC_DEFINE these.
3110 (acconfig.h): #undef the above symbols.
3112 * Makefile.in (libobjs): Add version.o.
3113 (installed_h_files): Add version.h.
3114 (c_files): Add version.c.
3115 (gen_c_files): Add version.x.
3116 (version.o): New rule.
3117 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
3118 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
3119 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,

3121 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
3122 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
3123 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
3124 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
3125 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
3126 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
3127 weaks.o): Add version.h to dependency lists.
3128 (markers.o): Remove duplicate rule.
3130 * version.h: New file.
3132 * version.c: New file.
3134 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3136 * symbols.c (scm_strhash): scm_downcase is now a function, not an
3137 array; use it appropriately. Since GCC is quite happy to
3138 subscript functions, it never warned us about this; we should use
3139 -Wpointer-arith in the future. I guess we never tested
3142 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3144 * socket.c: Doc and copyright fixes.
3146 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3148 * debug.c: Fixed and improved gdb support.
3150 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3152 * socket.c: Added declaration of inet_aton to avoid compiler
3153 warning. (Hope this solution is correct.)
3155 * stime.c: Added declaration of ftime. (This is missing in
3158 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
3160 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3162 * Makefile.in (c_files): add strerror.c.
3164 * strerror.c: new file from Emacs' sysdep.c.
3165 maybe configure should also check for sys_errlist.
3167 * configure.in (AC_REPLACE_FUNCS): add strerror.
3169 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3171 * debug.c (scm_init_debug): Added initialization for
3172 scm_evaluator_traps.
3174 * debug.h, debug.c: Various name changes.
3175 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
3176 "debug-options-interface". See commentary in options.c.
3178 * options.h, options.c: Options now have documentation strings.
3179 Also added a long explanatory commentary.
3181 * eval.c, print.h, print.c, read.h, read.c: Modifications to
3184 * gscm.c, init.c, root.c, throw.c: Bug fixes:
3185 last_debug_info_frame is now updated in all cases.
3187 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
3190 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3192 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
3193 Added option STACK_CHECKING.
3195 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3197 * Makefile.in: Added {debug,options,srcprop}.{h,c}
3199 * __scm.h: Removed symbols for debugging support.
3201 * acconfig.h: Added symbols for debugging support.
3203 * configure.in: Added user option for debugging support.
3204 --enable-debug will include the debugging code into libguile.a.
3206 * continuations.c (scm_make_cont): Enlarged the #if 0 around
3207 scm_relocate_chunk_to_heap.
3209 * debug.c: New file: low-level debugging support. It also
3210 includes support for debugging with gdb. (The extensions to gdb
3211 are written by Per Bothner at Cygnus.)
3213 * debug.h: New file: low-level debugging support.
3215 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
3216 argument pairs. Extensive modifications to the debugging
3217 evaluator. Added "SECTION:" commentaries to clarify what happens
3218 when, during double compilation. Renamed EVALIMP --> EVALIM.
3219 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
3220 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
3221 the beginning of the file. New procedure: scm_unmemocopy.
3222 Added some global state variables needed by the debugging
3223 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3224 check_entry, check_apply, check_exit, debug_options and
3225 evaluator_traps. New acro: undefine.
3227 * eval.h: Renamed EVAL --> XEVAL.
3229 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3230 --> scm_make_weak_key_hash_table.
3232 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3233 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3235 * libguile.h: Conditionally include debug.h
3237 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3238 scm_object_properties shouldn't return handle. `handle' now gets
3239 initialized in scm_set_object_properties_x. scm_object_properties
3240 doesn't any longer create an entry in scm_object_whash.
3242 * options.c: New file: handling of run time options.
3244 * options.h: New file: handling of run time options.
3246 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
3248 * print.c: New procedure: scm_print_options
3250 * print.h: Defines for print options.
3252 * read.c: New procedure: scm_read_options
3254 * read.h: Defines for reader options.
3256 * root.h: Added scm_source_whash among scm_sys_protects.
3258 * srcprop.c: New file: source properties.
3260 * srcprop.h: New file: source properties.
3262 * throw.c (jbsmob): Jump buffers are now correctly allocated.
3263 (Bug found by A. Green.)
3265 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3267 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3269 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3271 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3273 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3274 and should be called by the final client.
3276 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3278 * gc.h: Use the PROTO macro when declaring functions.
3279 * gc.c: Use the PROTO macro when declaring static functions.
3280 Remove the CPP hair around function definitions.
3282 * gc.c (scm_init_storage): Initialize scm_asyncs.
3284 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3285 preprocessor symbol; "__scm.h" is where it might get #defined.
3286 * __scm.h: Similar: #include <scmconfig.h> before testing
3289 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3291 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3293 * init.c (scm_boot_guile): Add init_func argument; call
3294 (*init_func) instead of calling scm_appinit; it's ucky to
3295 hard-code names for the user's procedures.
3296 * init.h (scm_boot_guile): Adjust declaration.
3298 * __scm.h (PROTO): New macro, for declaring functions with
3301 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3302 eliminate all the __STDC__ conditionals.
3303 (scm_boot_guile): Add declaration.
3304 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3305 Remove __STDC__ conditionals around function definitions; the
3306 declarations in init.h will provide the same information, more
3309 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3310 complain about it in the error message; the error message is
3311 adequate without that note, and there's nothing the user can do
3314 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3316 * Makefile.in (ancillary): Drop def.sed.
3318 * posix.c (scm_init_posix): Use numeric values, rather than
3319 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3320 F_OK. The symbols aren't available on some systems, and I'm
3321 pretty sure their values are fixed by common widespread practice.
3322 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3324 More functions unavailable on some systems.
3325 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3326 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3328 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3329 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3330 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3331 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3332 stub that signals an error as the #else.
3334 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
3336 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
3338 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
3340 * unif.c: include ramap.h.
3342 * read.c (endif): case_insensative_p renamed case_insensitive_p.
3344 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
3346 * ports.c: include sys/ioctl.h.
3348 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
3350 * configure.in: check for sys/ioctl.h.
3352 * ports.c: include <malloc.h> not "malloc.h".

3386 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
3388 Changes for NeXT, suggested by Robert Brown.
3389 * configure.in: Call AC_TYPE_MODE_T.
3390 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
3391 NeXT. Put header file list in alphabetical order.
3392 * configure, scmconfig.h.in: Regenerated.
3393 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.

3408 * ioext.c (fileno): renamed from %fileno.
3409 (soft-fileno): deleted.
3411 * ports.c (scm_port_revealed): don't need to check for -1 from
3413 (scm_set_port_revealed_x): return unspecified, not #f.

3425 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3426 This is necessary on Ultrix, and doesn't hurt portability.
3428 * Makefile.in (dist-dir): New target, implementing a new dist system.
3429 (installed_h_files): Put in alphabetical order.
3430 Remove duplicate entries for markers.h and unif.h.

3436 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3438 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3439 every if must have an else, or else the whole command has a
3440 non-zero exit code whenever the if's condition is false.
3442 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>

3506 * ports.c (scm_ports_prehistory): size malloced here doesn't
3507 matter so long as it is non-0 (got rid of "* 4").
3509 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3511 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3512 since its definition was bogus).
3514 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3516 * mallocs.[ch]: back again (for rx at least).
3518 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3520 * ports.c: removed functions relating to the mapping between ports
3521 and descriptors. (That stuff is unix-specific and should be collected
3522 in a separate library).

3529 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3530 handled correctly (SCM_FREEP was applied to them) -- test for
3531 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

3699 initialization to fix a race condition.
3701 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

3725 set the multi_byte flag correctly in symbols. This is wrong.
3726 intern_obbary_soft and msymbolize should take an extra parameter.

3728 The weird symbol syntax is also a bit bogus (emacs doesn't quite
