3 Handle short and long long uniform arrays properly. (Thanks to
5 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
6 raeql_1): Add cases for scm_tc7_svect (short vectors) and
7 scm_tc7_llvect (long long vectors).
9 Change the way libguile and boot-9.scm are timestamped, to try to
10 get rid of these spurious mismatch warnings. Now both
11 libguile/versiondat.h and ice-9/version.scm are generated directly
12 by the configuration process, rather than having version.scm
13 generated directly, and libguile/versiondat.h generated by the
14 Makefile, which is generated by configure. It seems that
15 sometimes the Makefile would change, but versiondat.h depends on
16 Makefile.in, not Makefile, so it wouldn't get rebuilt.
17 * Makefile.am (versiondat.h): Target removed; this is generated
18 directly by the configure script now.
19 (BUILT_SOURCES): Remove versiondat.h.
20 * versiondat.h.in: New file, transformed by the configure script
22 * Makefile.in: Regenerated.
24 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
25 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
26 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
27 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
28 if we want to use them in a header file some day, we can. (Thanks
31 * stime.c (scm_get_internal_real_time): Do the arithmetic using
32 SCM numbers, so we won't have rollover problems; the range of a
33 signed long in milliseconds is about 25 days. (Thanks to Karl
36 Don't redefine sleep and usleep.
37 * coop.c (sleep, usleep): Remove declarations; we don't use or
38 redefine these any more.
39 (scm_thread_usleep, scm_thread_sleep): New functions which do the
40 job of usleep and sleep in a thread-friendly way. We can use
41 these in the rest of Guile. Define versions for systems both with
43 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
44 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
45 we're just using it, not redefining it, we can use a K&R style
47 (sleep): Declare this, too, if the system hasn't.
48 (scm_sleep, scm_usleep): Use scm_thread_sleep and
49 scm_uthread_sleep if they're available; otherwise, just call the
51 * scmconfig.h.in: Regenerated.
53 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
55 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
57 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
61 The argument type of usleep varies from system to system,
62 as does the return type. We really shouldn't be redefining usleep
63 at all, but I don't have time to clean that up before the 1.3.
64 release. It's on the schedule for afterwards. (Thanks to Julian
66 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
68 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
69 * scmconfig.h: Regenerated.
71 * simpos.c (scm_software_type): Procedure deleted. This isn't the
72 right way to handle system variation. Autoconf's approach is the
74 * simpos.h (scm_software_type): Declaration deleted.
76 * script.c (scm_find_executable): Don't test if unix is #defined
77 here; first, NetBSD doesn't #define it, and second, it's the wrong
78 way to go about these things. (Thanks to Perry Metzger.)
79 (dld_find_executable): Delete this MSDOS support code. This isn't
80 the way we want to support this; it needs to be rethunk at a
83 * genio.c (scm_do_read_line): Don't just politely check that the
84 line was either non-empty or EOF. Abort if it's empty and not
87 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
89 * scmconfig.h.in: Regenerated.
91 * libguile.h: Don't omit the dynamic linking functions. (Thanks
94 * genio.c (scm_do_read_line): Count lines correctly when the file
95 doesn't end in a newline.
97 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
99 * genio.c (scm_do_read_line): Maintain the line count correctly.
100 (Thanks to Harvey J. Stein and Greg Harvey.)
102 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
105 * numbers.c (big2str): Protect t from garbage collection until
106 we're done. (Thanks to Gary Houston.)
108 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
110 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
112 * Makefile.in: Regenerated.
114 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
115 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
118 Do magic to mix reads and writes on stdio FILE-based ports.
119 (Thanks to Christian Lynbech.)
120 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
122 (pre_read, pre_write): New functions.
123 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
124 local_fputs): Call them.
125 (local_fflush): Mark the port as ready for reading and writing.
126 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
127 flags on new port objects. This might not be accurate --- who
128 knows what state the FILE * is in when we get it --- but it won't
129 do extraneous calls to fflush or fseek, so it's no worse than the
130 behavior before this change.
131 * ports.h: Add comment.
133 Centralize the creation of port objects based on stdio FILE * in
134 fports.c; don't just throw them together anywhere.
135 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
136 what the rest of Guile wants. Don't set the revealed count;
137 that's only appropriate for stdin, stdout, stderr.
138 (scm_standard_stream_to_port): This function does set the revealed
140 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
141 not scm_stdio_to_port.
142 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
143 * fports.c (scm_open_file): Same.
144 * posix.c (scm_pipe): Same.
145 * socket.c (scm_sock_fd_to_port): Same.
146 * ioext.c (scm_fdopen): Same.
147 (scm_freopen): Moved from here to...
148 * fports.c (scm_freopen): ... here. This is really something that
149 munges the internals of an fport, so it should go here.
150 * fports.h (scm_stdio_to_port): Adjust prototype.
151 (scm_standard_stream_to_port, scm_freopen): New protoypes.
152 * ioext.h (scm_freopen): Prototype removed.
154 * filesys.c (set_element, get_element): This can work on both pipe
155 and file ports, so use SCM_FPORTP to typecheck, instead of testing
158 * scmconfig.h.in: Regenerated.
160 Change the definition of the functions in scm_ptobfuns so that
161 they get passed the port object, not the port's stream.
162 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
163 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
164 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
165 Pass the port itself to the scm_ptobs function.
166 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
167 scm_generic_fgets): Same.
168 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
169 getc_void_port, fgets_void_port, close_void_port): Just change the
170 argument names; these functions don't really do anything.
171 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
172 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
173 port as an argument, and use SCM_STREAM to get the stdio FILE *.
174 Also, use prototyped definitions, and get rid of the extra
176 (scm_fptob, scm_pipob): We don't need casts here any more.
177 * strports.c (prinstpt): Use prototype declarations.
178 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
179 and use SCM_STREAM to get the string info. Also, use prototyped
180 definitions, and get rid of the extra declarations.
181 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
184 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
185 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
187 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
188 scm_fgets, for consistency.
189 (scm_fptop, scm_pipob): References updated.
191 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
193 Include the source location in error messages for scripts.
194 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
195 stack is still there when we catch the error.
196 * throw.c (handler_message): If we are handling an error with a
197 message, then put together the proper arguments and call
198 scm_display_error, instead of scm_display_error_message. That
199 displays source location, if it can find it.
201 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
203 * gc.c (scm_unprotect_object): Change this so that calls to
204 scm_protect_object and scm_unprotect_object nest properly.
205 (scm_protect_object): Doc fixes.
207 * strings.c (scm_string_set_x): Require the argument to be a
208 writable string, not a substring or a symbol.
209 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
210 (Thanks to John Redford and Charbel Jacquin.)
212 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
214 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
216 * eval.c (safe_setjmp): Remove this misunderstanding.
217 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
220 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
222 * libguile.h: Mark these as C declarations, for compilation by C++
225 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
226 __cplusplus clause. I seriously doubt this ever worked the way
227 the author seems to have intended.
229 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
231 Utterly needless cleanups to hopelessly messy code.
232 * ports.c: Doc fixes.
233 (scm_fflush): Moved to ...
234 * genio.c (scm_fflush): ... here, amongst all the other port
235 method invocation functions.
236 * genio.h, ports.h: The prototype moves too.
238 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
240 * backtrace.c (display_error_body): The current frame does not
241 always have a parent frame; consider a function called directly
242 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
245 * alloca.c (alloca): Undo yesterday's changes, and simply call
246 malloc directly for storage, and abort if we don't get what we
247 want. The situation is much simpler --- just call malloc. Emacs
248 has bizarre/evil requirements (signal handlers might malloc unless
249 you set this global flag, so you have to set the flag around all
250 calls to malloc) which we are certainly not going to conform to,
251 so we can do the simple and obvious thing.
253 * coop.c (coop_condition_variable_wait): Make this function
254 static. It's only useful internally --- you should never just
255 wait on a condition variable.
256 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
258 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
260 * unif.c (scm_array_set_x): Accept any kind of number as an
261 element for a uniform vector of doubles. This is more consistent
262 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
264 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
265 works; I can't conveniently test it myself. (Thanks to Dvid
266 Tillman for the bug report.)
270 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
271 from here, not from scm_compile_shell_switches (which is a pretty
272 dumb place to do it).
273 (scm_load_startup_files): New function.
274 (scm_ice_9_already_loaded): Variable moved to here from script.c.
275 * script.c (scm_compile_shell_switches): Don't load the startup
277 (scm_ice_9_already_loaded): Variable moved.
278 * init.c (scm_load_startup_files): Prototype for new function.
279 * gh_init.c (gh_enter): Doc fix.
281 1998-10-03 <jimb@savonarola.red-bean.com>
283 Some anti-warning changes from Greg Harvey.
284 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
285 warnings when it doesn't understand our NORETURN declarations in
287 * posix.c (scm_mknod): Similar.
289 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
291 * posix.c (scm_getpwuid): If we can't find an entry, return our
292 own message, instead of using scm_syserror --- the getpwMUMBLE
293 functions don't set `errno' to anything interesting.
295 1998-10-03 <jimb@savonarola.red-bean.com>
297 Get rid of warnings from the cooperative threading system.
298 * threads.h (scm_single_thread_p, scm_yield,
299 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
300 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
301 scm_wait_condition_variable, scm_signal_condition_variable): Add
302 prototypes for these Scheme-visible functions.
303 * coop-defs.h (coop_next_runnable_thread,
304 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
305 Prototypes for these here, even though they're from iselect.c.
306 (coop_condition_variable_wait, coop_join): Add prototypes.
307 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
308 scm_threads_free_condvar): Make these smob functions static.
309 * coop-threads.h (coop_init): Give this a real prototype.
310 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
311 (coop_next_runnable_thread): No need to provide prototype; it's in
314 * scmconfig.h.in: .detarenegeR
316 * iselect.c, threads.c: Doc fixes.
318 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
320 * Makefile.in: Regenerated with a patched automake, to get
321 dependency generation right when using EGCS.
323 * inet_aton.c (inet_aton): Add prototype, to remove compiler
324 warning. (Thanks to Robert Pluim.)
326 * inet_aton.c (inet_aton): Reassure the compiler that the
327 arguments to the <ctype.h> macros are all unsigned characters, not
330 1998-10-03 <jimb@savonarola.red-bean.com>
332 Getting rid of more warnings...
333 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
334 today's change to ../configure.in.
335 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
336 * scmconfig.h.in: Regenertaded.de.,.__
337 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
338 (scm_localtime, scm_mktime): Use a const char * to manipulate the
341 * readline.c: Doc fix.
342 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
343 * readline.h (scm_filename_completion_function): Add prototype.
344 (scm_init_readline): Make this into a prototype.
346 * readline.c (scm_filename_completion_function): Use SCM_PROC to
347 declare this, instead of calling scm_make_subr manually.
349 1998-10-02 <jimb@savonarola.red-bean.com>
351 * readline.h (scm_init_readline): Add prototype for this.
352 (scm_init_readline): Make this a real prototype.
354 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
356 Warning fixes from Maciej Stachowiak:
357 * backtrace.h (scm_display_application, scm_backtrace): Add
359 * debug.c (scm_m_start_stack): Make this function static.
360 * fluids.h (scm_fluid_p): Add prototype.
361 * procprop.c (scm_i_procedure_arity): Make this function static.
362 * regex-posix.c (scm_regexp_error_msg): Make this function static.
363 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
364 * root.h (scm_dynamic_root): Add external prototype.
365 * scmsigs.h (scm_usleep): Add external prototype.
366 * script.h (scm_init_script): Use prototype, not K&R decl.
367 * stacks.h (scm_stack_id): Add external prototype.
368 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
370 1998-09-30 Mark Galassi <rosalia@cygnus.com>
372 * gh.h: took out the definitions of vset and vref, since they are
373 replaced by the proper vector routines that correspond to the R4RS
376 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
378 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
379 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
380 third argument, a C expression that should result in a SCM value,
381 which is used to initialize the variable. Reimplemented
382 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
385 * version.h (scm_libguile_config_stamp): Add prototype.
386 (From Maciej Stachowiak.)
388 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
390 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
391 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
393 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
395 * print.c (scm_iprin1): Rather than having one i, and using it in
396 several places, declare a fresh i local to each block where it is
397 used, and give it a signedness appropriate to its use in each case.
400 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
403 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
404 signed/unsigned clashes.
406 * posix.h (scm_tmpnam): Added prototype.
408 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
409 scm_make_subclass_object): Add external prototypes.
411 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
412 comparison is okay here.
414 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
416 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
417 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
419 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
422 * load.c (swap_port): Make this function static.
424 * load.c (scm_search_path): Make max_path_len and max_ext_len
425 unsigned, since they're compared against string sizes.
427 * load.c (init_build_info): Make i unsigned.
429 * ioext.h (scm_read_line): Add prototype.
431 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
432 scm_hash_fn_remove_x): Make hash bucket index local variable k
433 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
434 accurately as possible.
436 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
437 comparisons, and range checking to make sure those casts are
440 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
441 signed/unsigned comparisons.
443 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
444 avoid signed/unsigned comparisons.
445 * smob.h (scm_numsmob): Change extern declaration to match.
447 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
448 avoid signed/unsigned comparisons.
449 * ports.h (scm_numptob): Change extern declaration to match.
450 (scm_current_load_port, scm_set_port_line_x,
451 scm_set_port_column_x): New prototypes.
453 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
454 test code, and it causes warnings.
456 * gh.h (gh_int2scmb, gh_uniform_vector_length,
457 gh_uniform_vector_ref): Added prototypes.
459 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
460 debugging support unconditionally. That's backtrace.c, stack.c,
461 debug.c, and srcprop.c.
462 (EXTRA_libguile_la_SOURCES): Omit those from here.
463 * Makefile.in: Regenerated.
465 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
467 * options.c (scm_options): Bugfix: Allow empty list of options!
469 * debug.c, debug.h (scm_single_step): Removed.
470 (scm_with_traps): New procedure. This procedure could easily be
471 written in Scheme but needs to be highly optimized.
473 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
475 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
476 Check SCM_TRAPS_P before trapping.
478 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
480 Changes to avoid signed/unsigned comparison warnings.
481 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
482 (scm_gc_sweep): Make n and j local to the blocks they're used in,
483 so they can have appropriate types for each application. Make i
484 signed. Use initializers in some spots. I'll probably pay for
486 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
487 (scm_must_realloc): Make nm unsigned.
488 (init_heap_seg): Make new_seg_index and n_new_objects signed.
489 (scm_init_storage): Use prototype-style definition, and make the
491 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
492 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
494 * filesys.c (scm_readlink): Make local vars rv and size ints, to
495 avoid signed/unsigned comparison warnings, and because the return
496 value of readlink may be -1. Don't bother casting the third
497 argument to readlink.
499 * filesys.c (scm_dirname, scm_basename): Move these to their own
500 page, at the end of the file.
501 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
503 * eval.h (scm_eval_options_interface): Add external prototype for this.
504 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
506 * eval.c (scm_lookupcar1): Make this static.
508 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
509 Make these prototype declarations, not K&R-style.
511 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
512 unsigned comparison warning.
514 * appinit.c: File removed. It had a single function in it, empty,
515 whose reason for existence is explained in no documentation or
516 comment. I think it's there as a default for some Tcl-style
517 initialization, but Tcl abandoned that approach a while ago.
518 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
519 (BUILT_SOURCES): Remove appinit.x.
520 * Makefile.in: Regenerated.
522 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
524 * Makefile.in: Regenerated using the last public version of
525 automake, not the hacked Cygnus version.
527 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
529 Remove Totoro kludge.
530 * Makefile.in, scmconfig.h.in: Regenerated.
531 * init.c, readline.c: Don't check if TOTORO is #defined.
533 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
535 * Makefile.am: Adjust for new thread configuration system.
536 (INCLUDES): Include the value of THREAD_CPPFLAGS.
537 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
539 (THREAD_LIBS): Definition deleted; automake will generate such
540 things automatically.
541 * Makefile.in: Regenerated.
543 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
545 Simplify smob and port marking; set the mark bit in the generic
546 marking code, and make marker routines only responsible for
547 turning up outgoing pointers.
548 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
549 before calling the marking function. Don't call the marking
550 function if it's zero.
551 * markers.c (scm_mark0): Just return #f. This function isn't
552 necessary at all now, but it's harmless to call it. We'll leave
553 it in so other folks' code doesn't croak at link time.
554 (scm_markcdr): Don't call SCM_SETGC8MARK.
555 * async.c (mark_async): Don't call SCM_SETGC8MARK.
556 * dynl.c (mark_dynl_obj): Same.
557 * root.c (mark_root): Same.
558 * srcprop.c (marksrcprops): Same.
559 * unif.c (markra): Same.
560 * variable.c (scm_markvar): Same.
561 * ports.c (scm_markstream): Same.
562 (void_port_ptob): Specify zero for our marking function.
563 * debug.c (debugobjsmob): Same.
564 * dynwind.c (guardsmob): Same.
565 * filesys.c (dir_smob): Same.
566 * fluids.c (fluid_smob): Same.
567 * fports.c (scm_fptob, scm_pipob): Same.
568 * mallocs.c (mallocsmob): Same.
569 * regex-posix.c (regex_t_smob): Same.
570 * smob.c (freecell, flob, bigob): Same.
571 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
572 * throw.c (jbsmob, lazy_catch_funs): Same.
574 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
576 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
577 scm_copy_tree on code in order not to let memoized code to leak
578 out. Thus, scm_copy_tree needs to copy vectors as well since
579 quasiquote can introduce evaluated code also inside vector
582 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
584 * eval.c (scm_copy_tree): Removed ability to copy vectors.
586 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
587 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
590 * unif.c: Say that ivect and uvect are of type signed and unsigned
591 long instead of int in commentary so that it correctly describes
594 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
596 * stime.c: Removed declaration of strptime. (It should be
597 declared by the system headers. If it turns out that some systems
598 don't, we'll handle that then.) (Thanks to Greg Troxel.)
600 * stime.h: Renamed TIMEH --> STIMEH
602 * backtrace.c (scm_display_error, scm_display_backtrace): In order
603 to increase portability, don't use structure assignment.
604 (Thanks to Nicolas Neuss.)
606 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
608 (finalize_fd_sets): Added empty statement after last case label.
609 (Thanks to Nicolas Neuss.)
611 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
614 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
616 * init.c, readline.c: OK, I won't have these readline.x bug
617 reports anymore. We've had them since April. The current reason
618 is a completely unintelligible failure of totoro.red-bean.com to
619 do the test for rl_getc_function in libreadline correctly. This
620 kludge overrides the test if we're on totoro so that the snapshot
621 generation process can work.
623 * readline.c: Define a strdup replacement if not existent on system.
625 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
627 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
628 This change makes scm_make_vector R5RS compatible. We cannot keep
629 the third argument since people want to be able to deduce the form
630 of the C function call only by looking at R5RS. (At the same time
631 we have removed some unnecessary complexity!)
633 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
634 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
635 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
636 argument in call to scm_make_vector.
638 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
640 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
641 This macro is useful in applications.
643 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
645 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
646 (scm_parse_path, scm_search_path): New Scheme level procedures.
648 * load.h (scm_internal_parse_path, scm_parse_path,
649 scm_search_path): Declared.
651 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
653 * filesys.c (dirname, basename): New procedures.
655 * init.c (scm_boot_guile_1): Removed condition around
658 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
659 new data type (guards) for representation of C level guards and
660 data on the wind chain.
661 (scm_internal_dynamic_wind): New function.
663 * dynwind.h: Declare scm_internal_dynamic_wind.
665 * root.h (scm_root_state): Added scm_cur_loadp.
667 * root.c (mark_root): Added comment about cur_loadp.
669 * load.c: #include "dynwind.h";
670 (scm_primitive_load): Use scm_inner_dynamic_wind to update
673 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
675 * ports.c (current-load-port): New procedure.
677 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
679 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
680 not a tty, return #f.
682 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
683 to Julian Satchell and Roland Kaufmann.)
685 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
686 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
688 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
690 * debug.h, debug.c (scm_start_stack): New function. Implements
691 the guts of old scm_m_start_stack.
693 * debug.c (scm_m_start_stack): Use scm_start_stack.
695 * init.c (scm_start_stack, scm_restart_stack): Renamed to
696 start_stack and restart_stack. (These have static scope.)
698 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
700 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
701 readline functions to come in release 2.3. (Thanks to Chet
703 (handle_errors): Use the above functions.
705 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
707 * readline.c: Improvements for readline support: Handle errors
708 better; Implement before-read-hook.
710 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
712 * init.c (scm_boot_guile_1), readline.c: Test for
713 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
714 assure that we have version >= 2.1.)
716 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
718 * readline.c (scm_readline): Defer interrupts while we're calling
721 * readline.c (scm_add_history): Bugfix: Do strdup before giving
722 away the string to add_history.
723 (completion_function): Do completion for readline. (Thanks to
725 (scm_filename_completion_function): New procedure: Filename
727 (current_input_getc): New function. Use this one instead of
728 standard getc from readline.
730 * throw.c, throw.h (scm_handle_by_throw): New function: This
731 handler throws errors to next handler on the dynwind chain.
733 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
735 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
738 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
740 * procprop.c (scm_i_procedure_arity): New function. Returns arity
742 (scm_procedure_properties): Modified to return arity together with
744 (scm_procedure_property): Added the read-only property `arity'.
745 (scm_set_procedure_property_x): It is an error to set the `arity'
748 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
749 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
751 * procprop.h (scm_sym_arity): New symbol.
753 * objects.c (scm_set_object_procedure_x): New procedure: Use this
754 to set the dispatch procedure of an operator or entity object.
756 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
757 Made procedure slots read-only.
759 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
760 scm_tcs_cons_gloc case in zero args switch; Fixed args
761 construction for operators in scm_tcs_cons_gloc case in two args
764 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
766 * fluids.c: Removed use of assert.h (in order to avoid
769 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
771 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
773 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
774 change makes the evaluator safer at the cost of evaluation speed.
775 It handles the case when the user has added a non-immediate
776 improper end of the application form, e.g., `(+ 0 . x)'.
777 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
778 minimize the extra cost as much as possible. The new code is
779 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
780 problem with structs planted directly in the code (e.g. by a
781 macro). This no longer causes segmentation fault. (Thanks to
784 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
785 arg `proc' in order to be able to throw errors; New argument
788 * Removed extra #include "debug.h"
790 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
792 * scmsigs.c: Declare usleep as returning void on some systems.
793 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
796 * coop.c (usleep): Return void on some systems.
798 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
800 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
802 * coop.c: Changed return type of usleep to int.
804 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
805 isn't found in the OS.
807 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
808 isn't enabled. (Thought that I had made this change ages ago...)
810 * iselect.c: Declare bzero if not defined by OS.
812 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
814 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
815 condition. (Thanks to John Tobey.)
817 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
818 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
821 * __scm.h: Start the long-term project of moving to POSIX threads.
822 Phase 1: Classification of all critical sections.
823 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
824 for A sections. (See comments in __scm.h for details.)
826 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
827 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
829 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
831 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
832 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
833 (libpath.h, versiondat.h): Replaced dependency on Makefile with
834 dependencies on $(srcdir)/Makefile.in
835 $(top_builddir)/config.status in order to avoid circularity.
837 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
838 from argc if argc was 0 initially.
840 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
841 in generation of libpath.h.
843 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
845 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
846 libguile from 2 to 3.
848 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
850 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
852 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
854 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
855 scm_set_port_column_x, scm_port_filename,
856 scm_set_port_filename_x): Removed optional arguments. Added
857 proper argument checking.
859 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
860 stack size in machine words.
862 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
863 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
864 to Ole Myren Röhne.)
866 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
868 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
869 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
871 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
874 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
875 procedure apply: Copy argument lists before pushing them unto the
876 environment so that the environment won't get mutated due to
877 manipulation of procedure arguments. This should perhaps be
878 regarded as a temporary solution until someone finds a more
879 efficient one. (Thanks to Maciej Stachowiak.)
881 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
883 * script.c (scm_compile_shell_switches): Use "guile" as default
884 zero arg if argc is NULL.
886 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
888 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
889 is zero. (Thanks to Dirk Herrmann.)
891 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
893 * ports.c (scm_add_to_port_table): First line is now line 0
894 (was 1). (Interface changed according to suggestion by Per
897 * backtrace.c (display_header): Add 1 to line and column numbers
898 when presenting them to the user.
900 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
901 from debug.c --> eval.c
903 * eval.h, eval.c (scm_eval_options_interface): New options
905 (SCM_EVAL_STACK): New option: Size of newly created stacks,
906 i.e. stacks for new threads.
908 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
910 * eval.c (unsafe_setjmp): Removed with #if 0.
912 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
915 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
916 to avoid compiler warnings.
918 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
920 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
922 * throw.c (handler_message): Print message on current error port
923 instead of default error port. (Thanks to Maciej Stachowiak.)
925 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
927 * ports.c (scm_add_to_port_table): allocate in units of
928 struct scm_port_table *, not struct scm_port_table.
929 * posix.c (scm_close_pipe): remove the port from the port table
931 Thanks to Rob Engle for both fixes.
933 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
935 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
936 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
938 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
940 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
942 * backtrace.c (display_error_body, display_backtrace_body),
943 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
944 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
945 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
946 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
949 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
950 don't receive the jmpbuf arg anylonger.
951 (scm_catch): Don't accept a #f tag.
952 (scm_throw): Check that key is a symbol.
953 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
955 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
957 * async.c (async_pending): Removed declaration.
959 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
961 * dynwind.c (scm_wind_chain): New debug function.
963 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
964 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
965 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
966 extra layer of functions around the body and handler of a thread.
967 This extra layer makes sure that the handler is called in the
968 dynamic context of the surround (= empty dynwind list), but under
969 the *dynamic root* of the body. We can not use the dynamic root
970 of the surround since that root belongs to another thread => stack
971 is not handled correctly. It may seem ugly to use this extra
972 layer, but the extra cost in terms of execution time is really
973 negligible compared to the total amount of time required to create
974 a thread, and it would reduce maintainability to duplicate the
975 crucial and complicated steps performed by cwdr.
977 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
978 (SCM_ALLOW_INTS): Added thread switching code before interrupts
979 get re-enabled. The important effect of this is that interrupts
980 are blocked during thread switching so that thread data structures
981 don't risk getting messed up by an unfortunate signal.
982 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
983 seems to do more aggressive optimization which actually move
984 instructions around in these macros in a fatal way. Therefore:
985 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
986 just superstitious...)
987 (SCM_TICK): Maybe do a context switch and take care of asyncs.
988 This macro should be used instead of SCM_ASYNC_TICK since the
989 latter doesn't do context switches any more.
991 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
992 instead of SCM_ASYNC_TICK.
994 * coop.c, iselect.c: Since thread switches are now performed with
995 interrupts masked, we can't use the old mechanism of delivering
996 signals immediately when they arrive. Signals must instead be
997 delivered when the asyncs run *after* the end of the critical
998 section in scm_internal_select. But this also means after context
999 switch so that the signal will be delivered to a different thread.
1000 To avoid this, I have changed the protocol of
1001 coop_wait_for_runnable_thread and friends so that they are allowed
1002 to return the original thread. So, if a signal arrives during
1003 scm_internal_select, we won't any longer be forced do a context
1004 switch, but can remain in the same thread and deliver the signal
1007 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1008 scm_asyncs_pending and made it global.
1010 * iselect.c: Small fixes.
1012 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1013 coop_condition_variable_init, coop_condition_variable_wait,
1014 coop_condition_variable_signal): Changed return type from `void'
1015 to `int'. This is to adhere closer to the pthreads interface.
1016 This, in turn, is part of an attempt to provide C versions of the
1017 mutex and condition variable primitives which can be part of a
1018 frontend to COOP or pthreads.
1020 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1021 coop_condition_variable_destroy): New functions.
1023 * coop-threads.c (scm_wait_condition_variable): Use
1024 coop_condition_variable_wait_mutex.
1026 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1027 Definitions moved to coop-defs.h.
1029 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1030 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1031 scm_cond_destroy): New C interface to mutecis and cond vars.
1033 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1035 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1037 * iselect.c: Now several threads can wait on the same file
1038 descriptor. The behaviour is compatible with OS select: All
1039 threads waiting for the fd return with the same status.
1041 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1043 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1044 Can spawn a thread from application C code.
1046 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1048 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1049 gh_doubles2scm): New functions.
1051 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1053 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1054 commented-out version of gh_eval_str()
1056 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1058 * socket.c (scm_bind): free soka after use.
1060 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1062 * stime.c (tzvar): new variable.
1063 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1064 avoid memory leaks when allocating.
1066 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1068 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1071 * gc.c, tags.h: Doc fixes.
1073 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1075 * eval.c (macro-eval!): Removed. This function was a design bug.
1076 It allowed memoized code to leak out to the scheme level. Most
1077 things that you could do with `macro-eval!' can be done with
1080 1997-12-20 Tim Pierce <twp@skepsis.com>
1082 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1083 scm_fgets now depends on ftell(3) to know how many bytes were
1086 1997-12-15 Tim Pierce <twp@skepsis.com>
1088 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1089 dealing with strings.
1091 1997-12-13 Tim Pierce <twp@skepsis.com>
1093 Make %read-line more suitable for implementing read-line efficiently.
1094 * ioext.c (scm_read_line): Strip the terminating newline from a
1095 string, and return a cons of the string and its terminator.
1097 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1098 of the string that is read is stored in this memory location.
1099 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1100 * genio.c, genio.h (scm_do_read_line): Update caller.
1101 * ports.h (scm_ptobfuns): Update typedef.
1102 * fports.c (scm_fptob, scm_pipob): Update struct.
1104 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1106 * filesys.c (set_element): Return file descriptor.
1107 (fill_select_type): Return the highest file descriptor.
1108 (scm_select): Tell select about the highest file descriptor. On
1109 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1110 Therefore the extra overhead for calculating the maximum fd seems
1111 to be more than compensated. Is this correct? In any case,
1112 scm_internal_select will be much faster with this info.
1113 (scm_select, fill_select_type, set_element): Don't accept any kind
1114 of object in the file descriptor list or vector.
1116 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1118 * iselect.c (finalize_fd_sets): Bugfix.
1120 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1122 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1123 when using scm_internal_select (since we might switch to another
1126 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1128 * simpos.c (scm_system): always define: use sysmissing if not
1129 available. Check for HAVE_SYSTEM instead of _Windows (does
1130 Windows lack system or does it have an unusable one?).
1131 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1132 Let the argument be optional: if not supplied, call system(NULL).
1134 * ports.c (scm_close_port): relax the type check from OPPORTP to
1135 PORTP; closing a closed port is allowed.
1137 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1139 * fports.c (scm_fgets): Return if the last char in a chunk is
1140 newline. When fgets returns a string whose length is `size-1', it
1141 is ambiguous whether a whole line was retrieved, so we must check
1142 explicitly whether a line terminator is present.
1144 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1146 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1147 before taking the CDR. (Thanks to Harald Meland.)
1149 * filesys.c (scm_stat): Slightly optimized.
1151 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1153 * ports.c (scm_close_port): Make sure the port is open before
1156 * guile-snarf.in: Pass args through to gcc in a way that preserves
1157 whitespace boundaries. (Thanks to Greg Badros.)
1159 1997-12-02 Tim Pierce <twp@skepsis.com>
1161 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1162 statement. (Thanks to Doug Evans for pointing this out.)
1164 1997-12-01 Tim Pierce <twp@skepsis.com>
1166 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1168 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1170 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1171 errno macro expansion of this field name. (errno is a C
1172 preprocessor macro on some systems.)
1174 1997-11-29 Tim Pierce <twp@skepsis.com>
1176 * iselect.c: Doc fix.
1178 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1180 * init.c (scm_start_stack): Removed initialization of
1181 scm_the_last_stack_var.
1183 * backtrace.h: Declare scm_the_last_stack_var.
1185 * backtrace.c: Define scm_the_last_stack_var.
1187 * root.c (mark_root): Don't mark the_last_stack_var.
1189 * root.h (scm_root_state): Removed the_last_stack_var.
1191 * throw.c: Added #include "fluids.h"
1192 (ss_handler): `the-last-stack' is now a fluid.
1194 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1195 --> the_last_stack_fluid.
1197 * backtrace.c: Added #include "fluids.h"
1198 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1199 (scm_backtrace): `the-last-stack' is now a fluid.
1201 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1202 after scm_init_fluids.
1204 1997-11-28 Tim Pierce <twp@skepsis.com>
1206 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1208 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1209 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1211 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1213 * iselect.c (coop_next_runnable_thread,
1214 coop_wait_for_runnable_thread): Disable interrupts so that no
1215 async is executed before a potential error_revive.
1216 (scm_internal_select): Disable interrupts during the parts of the
1217 code which manipulate the sleep queue and the file descriptors.
1219 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1221 * Makefile.am: Added iselect.c and iselect.h.
1223 * coop.c (coop_qinit): Initialize fields used by
1224 scm_internal_select.
1225 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1226 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1227 replacement in iselect.c.
1228 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1229 coop_join): If GUILE_ISELECT enabled, use
1230 coop_wait_for_runnable_thread instead of
1231 coop_next_runnable_thread.
1232 (usleep, sleep): New replacements for system functions if
1233 GUILE_ISELECT is enabled.
1235 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1237 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1239 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1240 iselect.h. Implement Scheme level `select' using
1241 scm_internal_select. (See NEWS.)
1243 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1245 * init.c: Call scm_init_iselect.
1247 * iselect.h, iselect.c: New files. Implements
1248 scm_internal_select. (See NEWS.)
1250 1997-11-27 Tim Pierce <twp@skepsis.com>
1252 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1253 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1254 and scm_must_free, since ultimately the string returned will be copied
1255 by scm_makfrom0str anyway. Also, read any characters that may have
1256 been pushed onto the port with scm_ungetc.
1257 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1258 * ioext.c (scm_read_line): Free string after Guilifying it.
1259 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
1261 1997-11-26 Anthony Green <green@hoser.cygnus.com>
1263 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1265 * gh.h: Safely wrap prototypes for c++ usage.
1267 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1269 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1270 gh_repl (argc, argv).
1272 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1274 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1275 and to invoke scm_shell().
1276 (gh_launch_pad): took out the loading of boot-9.scm from here,
1277 since it is probably best to let the user control that. In fact,
1278 gh_repl() now invokes scm_shell() which does that.
1280 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1282 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
1285 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
1287 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
1288 yesterday's underscore patch. (Thanks to Marius Vollmer for
1291 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
1293 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
1294 DLSYM_ADDS_USCORE is not defined.
1296 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
1298 * gh_data.c (gh_uniform_vector_length):
1299 (gh_uniform_vector_ref): started implementing the uniform types in
1302 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1304 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1305 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1307 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1309 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1310 configure.in was changed).
1312 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1314 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1315 * Makefile.in: Regenerated.
1317 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1319 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1320 OPORT is an `open' port, not an output port.
1322 * filesys.c (scm_close, set_element, get_element, scm_chown,
1323 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
1324 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
1325 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
1326 scm_close_port, scm_port_line, scm_set_port_line_x,
1327 scm_port_column, scm_set_port_column_x, scm_port_filename,
1328 scm_set_port_filename_x, scm_port_mode,
1329 scm_close_all_ports_except, scm_set_current_output_port,
1330 scm_set_current_error_port): Likewise
1331 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1332 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1334 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1335 * backtrace.c (display_backtrace_body): Likewise
1336 * fports (scm_setvbuf): Likewise
1337 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
1338 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
1339 scm_getpeername, scm_send, scm_sendto): Likewise
1340 * unif.c (scm_uniform_array_write): Likewise
1342 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1344 Minor problems with substring-related tag changes.
1345 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1346 exactly what we want to leave in to detect substrings.
1347 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1348 * tags.h: Fix diagrams and comments describing the S tag bit;
1349 remove vestigial remarks about the D tag bit.
1350 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1351 * strings.c: Formatting tweaks.
1353 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1354 variable first; then SCHEME_LOAD_PATH, with a warning message.
1355 (scm_parse_path): New function.
1356 * script.c: Doc fixes.
1358 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1360 Readline support, from Daniel Risacher.
1361 * readline.c, readline.h: New files.
1362 * init.c: #include "readline.h".
1363 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1364 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1365 * Makefile.in: Regenerated.
1366 * scmconfig.h.in: Regenerated, after change to ../configure.
1368 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1370 * gh.h: gh_vector_set -> gh_vector_set_x
1372 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1374 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1375 with the ! -> _x mapping when going from Scheme to C.
1377 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1379 * gh.h (gh_reverse):
1387 (gh_assoc): added these gh_ functions implemented as macros.

1390 (gh_string_equal_p): added these two missing predicates.
1392 * gh_list.c (gh_append):
1397 (gh_set_cdr_x): added these routines as I go through and try to
1398 complete the picture R4RS functions that should be mirrored in the
1401 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1403 * tags.h (scm_tc7_substring): Changed the comment and code to
1404 conform with the changes below. Folks! We have suddenly two new
1405 free tc7 codes!!! Jummy, jummy!
1407 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1409 * Makefile.in: Rebuilt.
1410 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,

1428 * tags.h (SCM_TYP7SD): Removed.
1429 (SCM_TYP7D): Removed.
1430 (scm_tc7_mb_string): Removed.
1431 (scm_tc7_mb_substring): Removed.

1434 Don't include "mbstrings.h".
1435 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1436 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1438 Don't include "mbstrings.h".
1439 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1440 (SCM_SYMBOL_SLOTS): Define as 4.
1441 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.

1462 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
1463 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
1465 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1467 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1469 * gh_test_c.c (c_vector_test): some improvements on the vector
1472 * gh.h (gh_vector): this used to exist but do the wrong thing.
1473 Now it (almost) does the right thing, though it takes a list
1474 instead of the individual arguments. I need to see how it could
1476 (gh_list_to_vector): added this function as a macro. Corresponds
1477 to Scheme's (list->vector ...).
1478 (gh_vector_to_list): added this function as a macro. Corresponds
1479 to Scheme's (vector->list ...).
1481 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1482 gh_vector_ref, so that it resembles the Scheme routines more.
1483 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1484 resembles the Scheme routines more.
1485 (gh_make_vector): this used to be (stupidly) called gh_vector().
1486 This is the right name, since it does the same thing as the Scheme
1487 (make-vector ...) procedure.
1489 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1491 * ports.h: #include "libguile/print.h"

1494 Some indentation fixes.
1496 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1497 longer a user field; New field: class_flags.

1504 gh_int2scmb(), which is now tagged as obsolete.
1506 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1508 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1509 macros should by convention not test for NIMPness.)
1510 (SCM_COERCE_OPORT): Adjust indentation.

1519 scm_struct_i_printer --> scm_vtable_index_printer
1520 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1522 * struct.c (scm_print_struct): Use new printer slot; Default
1523 printing: Also output hex code of vtable so that type identity
1524 will be indicated as well.
1525 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1526 Removed struct_printer_var; Removed struct-vtable-offset;
1527 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1528 vtable-offset-user): New constants.
1530 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.

1533 the type represented by this vtable.
1535 * print.c (scm_iprin1): Don't print arguments of macro
1536 transformers. (They are always: exp env.); Bugfix: Unmemoize
1537 transformer source with correct environment.
1539 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1541 Streamlining of call-with-dynamic-root:
1543 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1544 there is now only one catch.
1545 (cwdr_outer_body): Removed.
1546 (cwdr_handler): New function.
1547 (scm_internal_cwdr): New function to perform the function of cwdr
1548 but take args that are more useful to C code. Also, the handler
1549 is now invoked *outside* of the new dynamic root, like the docs
1550 say. We no longer have to catch absolutely all errors, the caller
1551 is responsible for using a handler that does not throw, if he
1553 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1554 * root.h (scm_internal_cwdr): New prototype.
1556 Even more but risky streamlining:
1558 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1559 allocation of the jumpbuf of a root continuation. The changes
1560 below are controlled by it. They are now deactivated.
1561 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1562 the JMPBUF of the scm_rootcont to NULL before returning.
1564 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1565 when they are non-NULL.
1566 (scm_gc_mark): Likewise, mark only when non-NULL.
1568 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1569 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1571 * gc.c (scm_done_malloc): New function.
1572 gc.h (scm_done_malloc): New prototype.
1574 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1575 (struct scm_print_state) [revealed]: New field.
1576 (scm_print_state_vtable): Make visible to the outside world for
1577 type checking purposes.
1578 (scm_valid_oport_value_p): New prototype.
1580 * print.c (scm_valid_oport_value_p): New function to check whether
1581 a certain value is acceptable as a port argument.
1582 (scm_print_state_vtable): New variable.
1583 (scm_free_print_state): Set `revealed' field to false.
1584 (scm_iprin1): Call user supplied closure printer with
1585 scm_printer_apply. Print in the traditional way when there isn't
1586 one or when it returns #f.
1587 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1588 Accept a port/print-state pair in addition to just a port.
1589 (scm_prin1): Don't return the print_state to the pool when it has
1591 (scm_printer_apply): Set `revealed' field of print_state to true.
1592 (scm_init_print): Set scm_print_state_vtable.
1593 (print_state_fluid, print_state_fluid_num): Removed.
1595 * throw.h (scm_handle_by_proc_catching_all): New prototype
1596 throw.c (scm_handle_by_proc_catching_all): New function
1598 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1600 * Makefile.in: Regenerated with automake 1.2c.
1602 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1604 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1605 was looping endlessly.
1607 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1609 * strports.c (scm_eval_string): Don't close the port.
1611 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1612 former returns a nice normal integer. (Thanks to Daniel
1615 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1617 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1618 makefile variable as a build parameter called LIBS. The
1619 build-guile program will use this, for the time being.
1620 * Makefile.in: Regenerated.
1622 Thanks to Shiro Kawai:
1623 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1624 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1627 * Makefile.in: Regenerated with automake 1.2a.
1629 * script.c (scm_compile_shell_switches): If we hit the -c or --
1630 arguments, don't set the car of (command-line) to scm_usage_name,
1631 the prettified name of the guile executable; give it the full
1632 path, the way shells usually handle $0.
1634 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1636 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1637 Scheme-level name `array-map' and renamed `serial-array-map' to
1638 `serial-array-map!'.
1640 * backtrace.c: Introduced exception handlers which now enclose
1641 `display-error' and `display-backtrace' so that error reporting
1642 won't get into infinite loops if an error occurs during displaying
1643 of the error. This can very easily happen with user supplied
1644 print call-back routines.
1646 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1648 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1649 the names `serial-array-map' and `array-map' should be removed.)
1651 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1653 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1654 Added #include "objects.h"
1656 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1657 Add #include "feature.h".
1659 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1660 (modinclude_HEADERS): Added objects.h.
1662 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1663 This test is needed at many places in the code and should be
1664 abstracted. (Motivated by the need of this test in libguiletk.)
1666 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1667 (scm_eval_string), load.c (scm_primitive_load,
1668 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1669 Use SCM_EOF_OBJECT_P.
1671 * eval.c (scm_init_eval): Add feature `delay'.
1673 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1675 * scmhob.h: Removed.
1677 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1679 * list.h (SCM_LISTn): New macros. Make list creation in C code
1680 prettier. The idea comes from STk.
1682 * sequences.h, sequences.c, append.h, append.c: Removed. These
1683 files implemented non-R4RS operations which would encourage
1684 non-portable programming style and less easy-to-read code.
1686 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1689 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1690 sequences.h, #include append.h.
1692 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1695 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1697 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1699 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1701 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1703 * eval.c: Added #include "objects.h"
1705 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1708 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1709 adjacent smob numbers.
1711 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1713 * procprop.h: Added declaration of scm_i_inner_name.
1715 * gsubr.c: New global symbol scm_i_inner_name.
1717 * debug.c (scm_procedure_name): Try procedure property
1718 `inner-name' if `name' fails.
1720 * print.c (scm_iprin1): Use scm_macro_name.
1722 * eval.c (scm_m_define): Give names to macros as well; Only the
1723 first top-level definition gives a procedure/macro a name.
1724 Otherwise confusing names can turn up in backtraces.
1725 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1726 `name'; Give names to macros as well.
1728 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1729 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1732 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1734 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1736 (prinmacro): Removed. The code has been moved/merged into print.c
1737 in order to decrease code redundancy. We want macros to print in
1738 a way equivalent to procedures, and it would be silly to duplicate
1739 the required code. (We don't want to maintain two places.)
1740 (macrosmob): Print field is now a NULL pointer.
1742 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1743 scm_macro_transformer): New prototypes.
1744 (scm_tc16_macro): Declared.
1746 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1747 are now printed in a way equivalent to procedures.
1749 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1751 * procs.h (scm_closure_p): Added declaration.
1753 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1755 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1756 Shouldn't pass "heap" as the subr name.
1758 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1760 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1761 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1762 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1763 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1764 SCM_BOOL_T. Any non-false value is true.
1766 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1768 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1769 scm_gensym): Added prototypes.
1771 * symbols.c (scm_gensym): New function. This will speed up
1772 certain types of applications (such as macro systems) which
1773 generate lots of symbols.
1775 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1777 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1779 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1781 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1782 specifier, since (2) or (2 . 3) would cause SEGV.
1783 (scm_transpose_array): more argument checking fixes.
1785 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1787 * Makefile.in: Regenerated.
1789 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1791 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1793 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1795 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1797 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1799 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1800 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1803 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1804 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1805 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1806 scm_array_p, scm_array_rank, scm_array_dimensions,
1807 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1808 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1809 scm_array_prototype): Added case scm_tc7_wvect.
1811 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1813 * errno.h: prototype for scm_strerror.
1814 * error.c (scm_strerror): new procedure.
1816 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1818 * list.c (scm_list_append_x): Allow non-pair as last argument.
1819 This is consistent with the R4RS append and is probably the
1820 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1822 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1824 * stime.h: prototype for scm_times.
1825 * stime.c (scm_times): new procedure.
1826 * ioext.c (scm_fseek): if the first argument is a file descriptor
1828 (scm_ftell): if the first argument is a file descriptor call lseek
1830 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1831 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1833 (scm_chown): if the first argument is a port or file descriptor,
1835 (scm_truncate_file): new procedure.
1836 Add DEFER/ALLOW INTS to a few other procedures.
1837 (scm_fsync): new procedure.
1838 (scm_open_fdes): new procedure.
1839 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1841 (scm_fcntl): the first argument can now be a file descriptor. The
1842 third argument is now optional.
1844 * posix.c (scm_execl, scm_execlp): make the filename argument
1845 compulsory, since omitting it causes SEGV.
1846 (scm_sync): return unspecified instead of #f.
1847 (scm_execle): new procedure.
1848 (environ_list_to_c): new procedure.
1849 (scm_environ): use environ_list_to_c. disable interrupts.
1850 (scm_convert_exec_args): take pos and subr arguments and
1851 improve error checking.
1853 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1855 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1856 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1857 argument to SCM_ASSERT. Furthermore, the name of the function
1858 should be passed as first argument when signalling
1859 SCM_WNA. (Thanks to Thomas Morgan)
1861 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1862 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1863 dispatches on the number of actual args has a default case
1864 reporting an internal error. This is a vestige from a version
1865 that mallocated a SCM vector to hold the arguments. In the
1866 current version this check is too late: if it ever happens we will
1867 have already overstepped the bounds of the array.
1869 Also, the patch [...] adds a check for too many actual arguments."
1871 mdj: Removed check for "internal programming error".
1873 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1875 * gh_io.c (gh_write): New function.
1877 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1878 throw.c (scm_internal_stack_catch): New sibling to the other catch
1879 functions. Code moved from gh_eval.c.
1880 throw.h: Added header.
1881 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1882 scm_internal_stack_catch.
1884 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1886 * ioext.h: fix up prototypes.
1887 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1888 Scheme name is now dup->fdes.
1889 (scm_dup_to_fdes): make the second argument optional and
1890 fold in the functionality of scm_primitive_dup.
1891 (scm_primitive_dup): deleted.
1893 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1895 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1896 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1897 ultrix are defined. Use setvbuf instead of setbuf.
1898 (scm_setvbuf): new procedure.
1899 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1900 (scm_setfileno): moved from ioext.c.
1901 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
1902 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.

1911 * print.c (scm_iprin1): Enter printed structures into the print
1912 state as nested data while they are printed.
1913 (print_state_fluid, print_state_fluid_num): New variables.
1914 (scm_init_print): Initialize them.
1915 (scm_iprin): If print_state_fluid carries a print_state, use that
1916 instead of creating a new one.
1917 (scm_printer_apply, apply_stub, struct apply_data): New
1918 definitions to help with calling printer functions written in
1920 * print.h (scm_printer_apply): New prototype.

1931 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
1933 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1934 SCM_ASSERT: arg comes before pos.
1936 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1938 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1939 to a list of length zero correctly.
1941 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1943 Supply an `fgets' method for port objects to do fast line i/o.

1957 * ioext.h: removed scm_duplicate_port prototype.
1959 * ioext.c (scm_primitive_dup2): return the new file descriptor
1960 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1962 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1963 stream has been set.
1964 (scm_duplicate_port): deleted, there's now an implementation in
1966 (scm_primitive_dup2): do nothing if newfd == oldfd.
1968 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
1970 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
1973 * ioext.h: new prototypes.
1974 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
1976 * fluids.c (next_fluid_num): don't do
1977 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
1979 * ports.h: prototypes too.
1980 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
1982 * fports.h: prototype too.
1983 * fports.c (scm_evict_ports): moved from ioext.c.

1992 and ports (scsh compatible).
1994 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
1997 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
1999 * fluids.c, fluid.h: New files.

2006 scm_make_initial_fluids.
2008 * root.h: Added "fluids" member to scm_root_state.
2009 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
2010 (scm_make_root): Call scm_copy_fluids to make fluid bindings
2011 unique for the new root when it has a parent.
2013 * smob.h: Include "libguile/print.h" to make scm_print_state
2016 * dynl.c (free_dynl_obj): New function to free the dynamic object
2017 data. (dynl_smob): Use it.
2018 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
2019 the dynamic object data below the linking of the object to avoid
2020 memory leak when the linking code throws an error. Now the code
2021 leaks a whole dynamically linked library when must_malloc throws,
2022 but that should be much less likely.
2024 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2026 Changes to compile under gnu-win32, from Marcus Daniels:
2027 * stime.c (tzset): If tzset isn't provided, make it a NOP.
2028 (scm_localtime): Change SCM_EOF to SCM_EOL.
2029 (scm_mktime): Likewise.
2030 * socket.c: Don't include sys/un.h unless autoconf tells
2031 us Unix domain sockets are available.
2032 (scm_fill_sockaddr): Ignore Unix domain code.
2033 (scm_addr_vector): Likewise.
2034 (scm_init_addr_buffer): Likewise.
2035 (scm_socketpair): Don't include unless socketpair was
2036 found during autoconf.
2037 * simpos.c (SYSTNAME): Treat cygwin like Unix.
2038 * scmsigs.c (scm_pause): Don't include unless pause was found
2040 * posix.c (scm_getgroups): Don't include unless support function
2041 was found during autoconf (in this case, getgroups).
2042 (scm_setpwent): For setpwent.
2043 (scm_setegid): For setegid.
2044 * net_db.c (scm_inet_netof): Don't include unless support
2045 function was found during autoconf (in this case, inet_netof).
2046 (scm_lnaof): For inet_lnaof.
2047 (scm_inet_makeaddr): For inet_makeaddr.
2048 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.

2055 * scmconfig.h.in: Regenerated.
2057 Thu Jul 10 00:22:24 1997 Jim Blandy <jimb@floss.red-bean.com>
2059 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
2060 scm_misc_error, not SCM_EOF.
2062 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
2063 arguments for formatting the error message, not SCM_BOOL_F. I
2064 think this is left over from the (eq? '() #f) days.
2066 * read.c (recsexpr): Give this a dummy definition if
2067 DEBUG_EXTENSIONS isn't #defined.
2069 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
2071 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
2074 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
2076 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
2079 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
2081 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
2082 alloca.lo will be included in @LIBLOBJS@. Something better than
2083 this should be possible.
2084 * Makefile.in: Regenerated.
2086 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2088 * simpos.h: prototype for scm_primitive_exit.
2089 * simpos.c (scm_primitive_exit): new procedure, terminates the
2090 process without unwinding the stack.
2092 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
2094 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2095 argument and logior its components together, so the user doesn't
2096 have to do this explicitly. Also, if regexp/basic is supplied, then
2097 turn off REG_EXTENDED.
2098 (scm_init_regex_posix): New regexp/basic symbol.
2099 (REG_BASIC): #define this if it is not already present.
2101 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2103 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
2104 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
2105 (CLEANFILES): New target, clean versiondat.h, libpath.h.
2106 (DISTCLEANFILES): New target, clean *.x.
2107 * Makefile.in: Regenerated.
2109 Tue Jun 24 00:29:07 1997 Jim Blandy <jimb@floss.red-bean.com>
2111 * script.c (scm_compile_shell_switches): Add 1997 to copyright
2112 years in usage message.
2114 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
2115 * Makefile.in: Regenerated.
2117 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2118 flag; I don't think we support it.
2119 (scm_make_regexp): Make sure the user doesn't pass the
2122 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2124 (scm_init_regex_posix): Define constants for the REG_mumble flags;
2125 name them according to the SCSH convention: regexp/mumble.
2127 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
2129 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
2131 * Makefile.am (libpath.h): Include the values of all the standard
2132 Makefile directory variables. Print a message, but don't print
2134 (versiondat.h): Print a message, but don't print all the commands.
2135 * load.c: #include "alist.h".
2136 (init_build_info): New function.
2137 (scm_init_load): Call it.
2138 * Makefile.in: Regenerated.
2140 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2142 * root.c: Establish a reliable catch-all handler for the new root.
2143 After all the Scheme handler function might signal an error too,
2144 and we don't want to lose that.
2145 (cwdr_inner_body): Renamed from cwdr_body.
2146 (cwdr_outer_body): New function, to establish the user's handler,
2147 and pass control to cwdr_inner_body.
2148 (cwdr): Establish the reliable catch-all handler here, and pass
2149 control to cwdr_outer_body.
2150 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2151 the user's handler through to cwdr_outer_body.
2152 * throw.c (scm_handle_by_message): Move guts into....
2153 (handler_message): New static function.
2154 (scm_handle_by_message_noexit): New function.
2155 * throw.h (scm_handle_by_message_noexit): New prototype.
2157 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2158 across this. Only works on GCC. Otherwise, we hope for the best.
2159 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2160 the feeling that real thread systems will not need this...
2162 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2164 Try to detect when people are using one version of libguile and a
2165 different version of ice-9. People have been skewing things and
2166 sending in bug reports.
2167 * Makefile.am (versiondat.h): New file to generate.
2168 * version.c: #include "versiondat.h", to get version info.
2169 (scm_libguile_config_stamp): New function.
2170 * script.c: #include "version.h".
2171 (scm_compile_switches): Call scm_version to get version number.
2172 * scmconfig.h.in, Makefile.in: Regenerated.
2173 * Makefile.in: Regenerated.
2175 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2176 primitive definitions under their Scheme names.
2178 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2179 1:2. Helps avoid confusion between installed and uninstalled libs.
2181 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2184 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2185 backslash from definition; this should be used like: GDB_INTERFACE;
2187 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2189 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2190 new port unbuffered until its stream has been set.
2192 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2194 * ports.h: new prototype.
2195 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2197 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2199 Make things compile neatly under Sun's C compiler.
2200 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2201 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2202 unsigned, because that's what the ANSI function takes.
2203 * extchrs.h (xmbtowc): Corresponding change to prototype.
2204 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2206 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2207 argument plain char *.
2208 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2210 * tag.c (scm_tag): Remove unreachable statement.
2211 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2212 top of the word, it should be unsigned.
2214 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2215 is defined, to avoid warnings; it's only used in the
2216 conflict-checking code. Which might go away anyway.
2217 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2218 conditionals; put the label definition in an #if too, to stifle
2221 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2222 ChangeLog-threads in the distribution.
2223 * Makefile.in: Regenerated.
2225 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2227 * guile-snarf.in: Changed regexp to support CPPs that insert
2228 whitespace between lexical tokens (which munges the `%%%' snarf
2231 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2233 * load.c (scm_init_load_path): Append $(datadir)/guile to
2234 %load-path, so modules do not have to be installed in Guile's
2235 current version directory.
2237 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2239 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2240 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2241 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2242 call the sysdep functions with deferred ints.
2243 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2244 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2245 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2248 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2251 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2253 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2255 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2257 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2260 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2262 * eval.c (scm_lookupcar1): New procedure to cope with a race
2263 condition during lookup (when using threads).
2264 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2265 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2268 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2270 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2271 supplied. (Change from Tim Pierce.)
2273 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2275 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2276 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2277 default and not `()'. `#f' is the canonical non-value in Scheme,
2280 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2282 * struct.c (struct_printer): New variable that holds a handle on
2283 the Scheme variable *struct-printer*. This variable can be set by
2284 Scheme code to override the printing of structures.
2285 (scm_print_struct): If struct_printer is set, call it. If it is
2286 not set, or returns #f, print the structure in the old fashion.
2287 Include "eval.h" for scm_apply.
2289 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2291 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2292 scm_struct_i_n_words to get the number of fields, not
2293 -scm_struct_n_extra_words.
2295 On the route to fancier struct printing:
2296 * struct.c (scm_print_struct): New function to print a structure.
2297 Include "genio.h" to support it. This function doesn't do
2298 anything interesting right now, but I think it should be here
2300 * struct.h: Include "print.h" and add prototype for
2302 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2303 print structures ourself.
2305 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2307 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2308 before applying the handler in case it doesn't return.
2310 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2312 * scmsigs.h, async.h: updated.
2314 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2317 * posix.c (scm_uname): interpret only negative values as an error.
2318 Solaris normally returns a positive value.
2320 * script.c (scm_compile_shell_switches): if we are not going into
2321 an interactive repl, set scm_mask_ints to zero so that asyncs can
2324 * simpos.c (scm_system): don't ignore/unignore signals around
2327 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2330 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2331 done in boot-9.scm instead.
2333 * scmsigs.c, async.c: Major rewriting of signal handling code.
2334 (scm_sigaction): new procedure.
2335 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2337 (scm_raise): return unspecified, throw error on failure.
2339 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2341 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2342 feature, to help boot-9.scm decide whether to import the regex
2345 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2347 * eval.c: Include scmconfig.h at the beginning of the file so that
2348 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2351 * regex-posix.c: #include "_scm.h" before conditionally #including
2352 <regex.h>; the former defines HAVE_REGCOMP.
2354 * regex-posix.c: #include <regex.h> conditionally, so the file is
2355 CPP'able (for dependency scanning) even on systems that don't have
2358 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2360 Add new R4RS-compliant syntax for keywords.
2361 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2362 regardless of the setting of the `keywords' read option.
2363 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2364 can be re-read no matter what the setting of the `keywords' read
2367 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2369 Add support for POSIX regular expressions.
2371 * regex-posix.c, regex-posix.h: New files. (Some code
2372 is taken liberally from rx/rgx.c in the old Guile dist.)
2374 * init.c: Include regex-posix.h.
2375 (scm_boot_guile_1): Call scm_init_regex_posix.
2377 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2378 Add regex-posix.[ch] sources.
2379 * Makefile.in: Regenerated.
2381 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2382 to do this automatically? It didn't for me, bleh.)
2384 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2386 * fports.c (print_pipe_port): New function.
2387 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2388 latter doesn't even take the right arguments.
2390 * Makefile.am: Increment shared lib revision number. I think
2391 sometimes the uninstalled Guile finds the installed shared lib;
2392 Gord says doing this might help. As things turned out, I can't
2393 say whether it does.
2394 * Makefile.in: Regenerated.
2396 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2397 passing it as the closure argument to scm_boot_guile. (Bill
2400 * ports.c (print_void_port, putc_void_port, puts_void_port,
2401 write_void_port, flush_void_port, getc_void_port, close_void_port,
2402 noop0): Use ANSI prototypes instead of K&R declarations, so the
2403 initialization of void_port_ptob gets aggressively type-checked.
2404 Fix arguments of print_void_port and write_void_port. (Bill

2438 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2440 * script.c (scm_find_executable): Use prototype-style definition
2441 here; apparently it's not quite right to have const in a prototype
2442 and then use a K&R declaration. I wonder if stuff like this will
2443 go away if we compile with -Wrequire-prototypes, or whatever that
2444 is... (Bernard URBAN)
2446 * scmhob.h: New text from Bernard URBAN.
2448 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2450 * script.c: Don't #define const on hpux. Configure takes care of
2451 this. (Thanks to Larry Schwimmer.)
2453 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2454 decide whether to #include <unistd.h>, instead of listing a bunch
2455 of systems. Don't #include stdio twice. Removed dyked-out
2456 definition of scm_find_impl_file.
2458 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2460 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2461 library version info to 1:0.
2462 * Makefile.in: Regenerated.
2464 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,
2465 gdb_interface.h, gdbint.c, gdbint.h, gh_data.c, gh_init.c,
2466 gh_io.c, gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c,

2468 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2469 throw.c: Update copyright years; these files have been worked on
2470 significantly in 1997, but only had copyright years for 1996.
2471 Also, change name of copyright holder on some from Mikael
2472 Djurfeldt to Free Software Foundation; he has signed papers
2473 assigning the changes to the FSF.
2475 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2476 reason not to give the user the option.
2478 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2479 Return #f on end-of-file when scanning table (i.e. when called
2480 with no arguments). Try to catch errors, when we can.
2481 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2483 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2484 external declarations. These are useful.
2486 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2488 * posix.c: don't include <sys/select.h> or define macros for
2489 select, since they were not used in this file.
2491 * filesys.c (scm_select): make the fifth parameter microseconds,
2492 not milliseconds. let the fourth parameter be either a real value
2493 or an integer or #f. The first, second and third arguments can
2494 now be vectors: the type of the corresponding return set will be
2496 (set_element, get_element): new static procedures.
2498 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2500 * strports.c (scm_eval_string): New function.

2507 * fports.c (local_pclose): New function.
2508 (scm_pipob): Use it in the initializer here.
2511 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2512 Use a meaningful error message when signalling an error. For
2513 this, scm_gethost must check h_errno rather than errno.
2515 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2517 * Makefile.in: Regenerated, using automake-1.1p.

2521 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2522 not SCM_UNSPECIFIED.
2524 * script.c (scm_compile_shell_switches): don't append (quit) if
2526 (scm_shell): call scm_exit_status and exit on the result of the
2529 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2531 Ensure that shared substrings are handled properly when passed to
2532 a system call or other foreign function. Many thanks to Tim
2534 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2535 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2536 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2537 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
2538 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
2539 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2540 (scm_display_error_message): use RO macros when strings may be RO.
2541 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2542 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2543 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
2544 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
2545 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
2546 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
2547 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2548 scm_strftime), vports.c (scm_make_soft_port): use
2549 SCM_COERCE_SUBSTR to make sure shared substrings are

2554 * error.c (scm_error): Add newline to error message.
2556 * init.c (scm_init_standard_ports): Doc fix.
2558 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2560 * dynl-shl.c: Completely replaced with new code from Bernard
2563 * script.c (scm_ice_9_already_loaded): New variable.
2564 (scm_compile_shell_switches): Use it.
2566 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2568 * filesys.c (scm_input_waiting_p): add missing third argument to
2571 * stime.c (scm_localtime): copy the result of localtime before
2572 calling gmtime in case they share a buffer.
2573 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2576 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2578 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2580 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2582 * Makefile.am (check-local): New target, which causes 'make check'
2583 to run gh_test_c and gh_test_repl, with some trivial input.
2584 * Makefile.in: Rgnrtd.
2586 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2588 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2591 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2593 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2594 sure how this was supposed to work.
2595 (scm_async_click): don't send SCM_TICK_SIGNAL.
2596 (scm_init_async): don't initialize %tick-thunk.
2598 * the following change doesn't affect the Scheme interface:
2599 gc-thunk is called at the end of garbage collection. however it's
2600 no longer implemented by pretending it's a signal.
2602 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2603 system async corresponding to scm_gc_thunk.
2604 * async.h: declare scm_gc_async.
2605 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2606 gc-thunk directly, instead of going through a signal handler.
2607 (scm_gc_async): new variable, points to the GC system-async.
2608 (scm_init_async): save the GC async as scm_gc_async instead
2609 of using system_signal_asyncs.
2610 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2612 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2614 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2615 Don't screw up if we're interrupted.
2616 * Makefile.in: Regeneradet.
2618 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2620 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2622 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2623 we're not using AM_INIT_GUILE_MODULE any more.
2624 * Makefile.in: Reneregated.
2626 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2628 Functions for finding variable bindings, grace à Tim Pierce.
2629 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2630 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2632 Get 'make dist' to work again.
2633 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2634 * Makefile.in: Regenerated, like a surry without a fringe on top.
2636 Changes for reduced Guile distribution: one configure script,
2638 * configure.in, configure: Removed.
2639 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2640 real configure script lives.
2641 * Makefile.in, scmconfig.h.in: Regenerated.
2643 * init.c: #include "script.h", to get prototype for script.c's
2646 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2648 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2649 scm_must_malloc, not raw malloc.
2651 * script.c (scm_compile_shell_switches): Dyke out debugging output
2654 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2656 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2658 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2659 system has them. Hope this is safe. Previously
2660 sys/timeb.h was included if HAVE_FTIME was defined or if
2661 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2662 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2664 * ioext.c (scm_setfileno): add missing third argument to
2665 scm_misc_error call.
2667 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2669 * eq.c (scm_equal_p): Correctly compare strings of different
2670 varieties. (Thanks to Tim Pierce.)
2672 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2674 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2675 #! block comment must occur on a line all by itself.
2677 Move most of the guts of shell command processing into libguile,
2678 so guile.c can be very small (and eventuallly auto-generated. (I
2679 mean, generated mechanically, not self-generated. Hmm.))
2680 * guile.c, script.c, script.h: New source files.
2681 * init.c (scm_boot_guile_1): Call scm_init_script.
2682 * libguile.h: #include "script.h".
2683 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2684 targets, for new executable.
2685 (libguile_la_SOURCES): Mention script.c.
2686 (modinclude_HEADERS): Add script.h.
2687 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2688 not dynamic linking is enabled. This is because we're generating
2689 executables now. Move CY_AC_WITH_THREADS call after those, so the
2690 values of cy_cv_threads_libs captures the libs chosen above.
2691 * Makefile.in, configure, aclocal.m4: Regenerated.
2693 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2694 We don't maintain this interface any more, and it just confuses
2697 * alloca.c: #include <scmconfig.h>, not <config.h>.
2698 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2699 it'll get included in disties.
2701 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2703 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2704 be distributed, because they confuse people.
2705 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2707 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2709 * configure.in: check for presence of gethostent (not present on
2710 OpenBSD by default).
2711 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2712 * configure, scmconfig.h.in: Regenerated.
2714 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2716 * backtrace.c (scm_backtrace): Split message string across
2717 newlines properly. GCC is more tolerant of this than other
2720 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2722 Merge threads directory into libguile.
2723 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2724 threads.h: New source files.
2725 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
2726 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2728 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2729 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2730 coop-threads.c.cygnus, coop-threads.h.cygnus.
2731 * configure.in: If we're using threads, include threads.o in
2733 * _scm.h, libguile.h: threads.h lives in this directory now.
2734 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2735 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2736 currently used, but brought along for information's sake.
2737 * ChangeLog-threads: log from old 'threads' directory.
2738 * Makefile.in, configure: Rebuilt.
2740 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2742 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2745 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2747 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2749 Merge GH interface library into libguile.
2750 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2751 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2752 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2753 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2755 (EXTRA_libguile_la_SOURCES): ... here.
2756 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2757 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2758 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2759 New variables, describing how to build the gh test programs.
2760 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2761 build the test programs, and we probably should have been linking
2762 libguile.la against them all along, to support AIX shared libs.
2763 Add cflags for threads to CFLAGS; add libs for threads to new
2764 variable THREAD_LIBS, used in Makefile.am.
2765 * ChangeLog-gh: log from old `gh' subdirectory.
2766 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2768 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2770 * acconfig.h: Undo change of Apr 9; including the definition of
2771 PACKAGE in the guile headers conflicts with applications' own
2773 * scmconfig.h.in: Regenerated.
2775 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
2777 * filesys.c (scm_fcntl): New function from Roland McGrath.
2778 (scm_init_filesys): New symbols for use with fcntl.
2779 * filesys.h: Added prototype.
2781 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
2782 when PROC is receiving no arguments.
2784 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2786 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2787 have S_IFSOCK. This is the case under Ultrix.
2789 * posix.c (scm_status_exit_val, scm_status_exit_val,
2790 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2791 Ultrix versions of WIFSTOPPED, etc., which assume that their
2792 arguments are lvalues (hmm).
2794 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2796 * eval.c: Doc fixes.
2798 * throw.c: Doc fixes; rearranged.
2800 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2802 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2804 * acconfig.h: Added entry for PACKAGE.
2805 * scmconfig.h.in: Regenerated.
2807 Changes to work with automake-1.1n, which has better libtool support.
2808 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2809 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2811 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2813 * Makefile.in: Rebuild.
2815 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2817 * stime.c (scm_mktime): take an optional zone argument.
2818 (scm_localtime): check putenv return value.
2819 (scm_strftime, scm_strptime): moved from posix.c. move #include
2821 stime.h, posix.h: update prototypes.
2822 (bdtime2c, setzone, restorezone): new static procedures.
2823 (scm_mktime, scm_strftime): use them.
2824 (scm_strftime): don't call mktime before strftime. Use
2825 filltime for return value.
2826 (filltime): convert NULL zname to #f.
2827 (scm_strptime): return a count of characters consumed, not
2828 the remaining string.
2830 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2832 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2833 (scm_mktime): likewise.
2835 Uncomment localtime and mktime.
2837 * configure.in: add AC_STRUCT_TIMEZONE.
2839 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2841 * stime.c (scm_init_stime): don't define ticks/sec.
2842 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2843 return value problem and is still portable.)
2845 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2847 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2848 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2849 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2850 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2851 cpp_err_symbols.c): Corresponding changes.
2852 * Makefile.in: Regenerated.
2854 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2856 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2857 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2858 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2859 * putenv.c: new file, from sh-utils 1.12.
2861 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2862 since allocation isn't for Scheme objects.
2863 (scm_putenv): copy strings before placing in the environment.
2865 * stime.c (scm_current_time): throw an error if time returns -1,
2866 instead of returning #f.
2867 (scm_get_internal_real_time, scm_get_internal_real_time): use
2868 scm_long2num for return value instead of SCM_MAKINUM.
2870 * stime.h: prototypes updated.
2872 * stime.c (scm_time_in_msec): apparently unused, deleted.
2874 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2876 * configure.in: check for gettimeofday.
2878 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2879 which may be more usefully portable than a gettimeofday interface.
2881 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2883 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2885 * Makefile.in: Regenerated.
2887 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2889 * stime.c (filltime): recovered static procedure.
2890 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2893 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2894 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2896 * posix.c (scm_mknod): split the mode argument into type and perms
2897 arguments, like the extra fields returned by stat.
2899 * fports.c (scm_pipob): set the close, free and print procedures.
2900 (scm_close_pipe): new procedure.
2902 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2903 define them in boot-9.scm
2905 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2907 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2908 wan't defined. Don't include fd.h.
2910 * Previously fd.h was regenerated whenever configure was run,
2911 forcing a couple of files to be recompiled.
2913 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2914 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2915 Check for _fileno as well as _file.
2917 * ioext.c: don't fd.h.
2918 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2921 * Change the stratigy for getting information about errno
2922 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2923 generating lists of symbols during the build process, which will
2924 not always work, include comprehensive lists in the distribution.
2925 To help keep the lists up to date, the "check_signals" and
2926 "check_errnos" make targets can be used.
2928 * configure.in: don't check for a command to extract errno codes.
2929 * Makefile.am: update file lists, remove errnos.list and errnos.c
2930 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2931 check_errnos targets.
2932 (CLEANFILES): remove errnos.c and errnos.list, add
2933 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2934 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2935 * errnos.default: deleted.
2936 * cpp_signal.c: new file.
2937 * cpp_errno.c: renamed from errnos_get.c.
2938 * cpp_err_symbols, cpp_sig_symbols: new files.
2939 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2940 * error.c (scm_init_error): #include cpp_err_symbols instead of
2942 * posix.c (scm_init_posix): don't intern signal symbols. #include
2945 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2947 * strop.c (scm_i_index): allow the lower bound to be equal to the
2948 length of the string, so a null string doesn't always give an error.
2950 * posix.h: new prototypes.
2951 * posix.c (scm_status_exit_val, scm_status_term_sig,
2952 scm_status_stop_sig): new functions, as in scsh. They break down
2953 process status values as returned by waitpid.
2955 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2957 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2958 configure doesn't know about it.
2960 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2962 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2964 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2965 which defines C variables with global linkage.
2967 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2969 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2972 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2974 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2975 has time to check why this doesn't work well with continuations.
2977 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2979 * Fix shell syntax error; some shells won't tolerate
2980 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2982 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2984 * posix.c (scm_uname): throw an error if uname fails instead
2987 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2989 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
2992 * async.c (scm_ints_disabled): definition moved from error.c.
2994 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2996 * acconfig.h: Removed PACKAGE.
2998 * scmconfig.h.in: Regenerated.
3000 * snarf.h: g++ says it's non-portable not to specify the first
3001 argument in a varargs declaration. I introduced the first
3002 argument by using preprocessor conditionals.
3004 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3006 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3007 (scm_freopen): use RO string macros for filename and modes.
3008 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
3010 * posix.c (scm_getgrgid): simplify conversion of name to C string.
3011 (scm_mknod): use RO string macros for path.
3013 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
3014 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3016 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3017 use SCM_ROSTRINGP and SCM_ROCHARS.
3019 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3021 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3024 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
3025 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
3026 support for byte vectors.
3028 * print.c (scm_iprin1): Limit number of vector elements printed
3029 according to pstate->length.
3031 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3033 * backtrace.c (scm_display_error_message): don't segv if message
3036 * error.h: prototype for scm_error_scm.
3038 * error.c (scm_error_scm): new procedure, reimplements scm-error
3039 in C and uses scm_error.
3041 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3043 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3044 pointer to the Scheme variable read-hash-procedures and intern it
3045 in scm_init_read. Modify scm_read_hash_extend and
3046 scm_get_hash_procedure to use the pointer.
3048 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3050 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3051 (SCM_KEYWORD_STYLE): defined.
3053 * read.c (scm_read_opts): add a keywords option. This isn't a
3054 boolean option, in case someone wants to add support for DSSSL
3056 Setup scm_keyword_prefix symbol.
3057 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3059 I've left keyword support disabled by default, since it doesn't
3060 seem to break the module system and it gives R4RS standard behaviour.
3061 It can be reactivated with (read-set! keywords 'prefix).
3063 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3065 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3066 before constructing arbiter.
3068 * eval.c (scm_m_define): Bugfix: Check that the object is a
3069 closure before setting the procedure property!
3071 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3073 * ports.c: Removed `ungetc-char-ready?'.
3075 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3077 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3078 (idea from Mikael: make it a pair so scm_permanent object only
3080 (scm_read_hash_extend): don't call scm_permanent_object.
3081 (ideas from Mikael): if chr is already in the list, replace its
3082 procedure instead of appending it again. If proc is #f, remove
3084 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3086 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3088 * gdbint.c (gdb_read): update scm_lreadr usage.
3090 * load.h: update prototypes.
3092 * load.c (scm_primitive_load, scm_read_and_eval_x,
3093 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3095 * read.h: add prototype for scm_read_hash_extend. Change args for
3098 * read.c (scm_read_hash_procedures): new variable.
3099 (scm_read_hash_extend): new procedure.
3100 (scm_get_hash_procedure): new procedure.
3101 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3102 for extended # processing.
3103 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3104 scm_read_token): remove case_i, sharp arguments. Change callers.
3106 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3108 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3109 (SCM_CASE_INSENSITIVE_P): define.
3111 * read.c: add case-insensitive option to scm_read_opts.
3112 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3113 to determine whether to convert symbol case.
3114 (default_case_i): definition removed.
3115 * read.c (scm_read_token): if case_i, downcase ic before doing
3118 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3120 * configure.in: Added configuration option `guile-debug'.
3121 Configure with --enable-guile-debug if you want a bunch of extra
3122 functions used for debugging when developing Guile.
3124 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3126 * procs.c (make-cclo): New undocumented debugging procedure: Make
3127 compiled closure with internal procedure PROC and length LENGTH.
3128 Only compiled if GUILE_DEBUG is defined.
3130 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3132 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3134 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3136 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3137 with 3 or more args internally to the evaluator.
3139 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3141 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3142 with 3 or more args internally to the evaluator. This is mainly
3143 because we don't want to pass entry and exit points of the
3144 debug support twice, but it also seems to increase the speed of
3145 the evaluator for such calls (e. g. (+ 1 2 3)).
3147 * backtrace.c (scm_display_application): New procedure:
3148 display-application; Set fancy printing parameters individually
3149 for different types of display (backtrace, error, application).
3150 (These should of course be customizable!)
3152 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3153 clear the CHECK-flags.
3155 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3157 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3159 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3161 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3162 from pairs with a GLOC in the car.
3164 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3165 otherwise `symbol-hash' will behave badly.
3166 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3167 we get segmentation fault!
3169 * symbols.c: Added #include "weaks.h". New functions:
3170 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3171 moved to an extraneous library when we split libguile.)
3173 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3175 * filesys.c (scm_stat): stat now takes fport arguments too as
3176 documented in the manual.
3178 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3180 * debug.c (scm_single_step): Bugfix: Call continuation with
3181 scm_call_continuation instead of throwing to it.
3183 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3185 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3186 argument wasn't declared to be optional.
3188 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3190 * stime.c (scm_init_stime): Add feature "current-time".
3192 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3194 * throw.h: prototype for scm_exit_status.
3195 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3196 args to derive an exit status. Allows (quit) to work from a
3198 (scm_exit_status): new function.
3201 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3203 * eval.c (scm_deval): Removed some old code.
3204 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3206 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3209 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3212 * procs.c: Introduce the existent C function scm_thunk_p at the
3213 Scheme level as well.
3215 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3217 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3218 used from C to easily lookup the value of a symbol in the current
3221 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3223 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3224 scm_init_unif in this file. This will also fix a previous problem
3227 * configure.in: Added AM_MAINTAINER_MODE
3229 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3231 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3234 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3236 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3237 source files that are not always included in libguile but should
3238 have their dependencies calculated by automake. This variable is
3239 recognized by automake, no further magic is needed.
3240 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3241 to deal exclusively with *.lo files, as it seems. The *.o files
3242 are built automatically when the corresponding *.lo file gets
3245 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3247 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3250 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3252 * unif.c (scm_array_set_x): minor change to argument error checking.
3254 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3256 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3257 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3258 They should only be included in the library at configure.in's
3260 (libguile_la_LDADD): Include the appropriate .lo files here.
3261 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3262 so we know when to build them (and their .lo bretheren).
3263 * configure.in (LIBLOBJS): New substituted variable. We let
3264 configure decide which .o files to include in LIBOBJS, and then
3265 put the corresponding list of .lo files in LIBLOBJS. The latter
3266 is what we pass to libtool.
3267 * Makefile.in, configure: regenerated.
3269 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3271 * symbols.c (scm_sysintern0): New function. Contains the core of
3272 old scm_sysintern but doesn't take a second value argument.
3273 (scm_sysintern): Now uses scm_sysintern0.
3274 (scm_sysintern_no_module_lookup): Renamed to
3275 scm_sysintern0_no_module_lookup and doesn't take a second value
3276 argument any longer.
3278 * symbols.h (scm_sysintern0: Added declaration.
3280 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3281 scm_sysintern when interning option keys. Otherwise we risk
3282 destroying the values of already interned variables.
3284 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3285 scheme-level boolean (use SCM_NFALSEP).
3287 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3289 (scm_backtrace): New function. (C version of old function from
3290 boot-9.scm) Motivation: Make it possible to display backtraces
3291 without depending on boot-9.scm. (I'm uncertain if this
3292 motivation is good enough...)
3294 * root.h (scm_root_state): Add member the_last_stack_var.
3295 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3297 * root.c (mark_root): Mark scm_the_last_stack_var.
3299 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3302 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3304 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3305 1. mark_lazy_catch didn't mark the smob.
3306 2. Both functions above have standard variants:
3307 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3308 free_lazy_catch --> scm_free0.
3310 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3312 * throw.c (scm_internal_lazy_catch): New function.
3313 (scm_lazy_catch): Rewritten to use it.
3314 (scm_ithrow): Handle the new lazy catch representation.
3315 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3316 that doesn't have a jmpbuf is a lazy catch clause.
3317 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3318 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3319 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3321 (scm_init_throw): Register the new lazy-catch smob type.
3322 * throw.h (scm_internal_lazy_catch): decl for new function.
3324 * throw.c (scm_internal_catch): Doc fixes.
3326 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3327 configure.in. Including this might cause problems if applications
3328 that link against libguile include their own copies of alloca, but
3329 if they're using autoconf, they should be adding libguile to LIBS
3330 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3331 the copy in libguile, and things will be okay. (I think.)
3333 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3335 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3337 strop.h: move prototypes too.
3339 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3341 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3344 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3345 etc. I deleted them from filesys.c long ago, but didn't
3346 notice they were here too (although ineffective since
3347 sys/stat.h wasn't included).
3349 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3351 * eval.c: Don't define alloca in GCC case. gcc will automatically
3352 use __builtin_alloca if appropriate.
3354 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3356 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3357 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3358 that values of automatic variables are preserved. See comments
3359 for safe_setjmp for details.
3361 Change from Thomas Morgan:
3362 * variable.c: Include eq.h.
3363 (var_equal): New function.
3364 (variable_smob): Use var_equal as the discriminator for variables.
3366 * throw.c (s_throw): Remove extraneous declaration.
3368 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3369 * eval.c: Add necessary CPP cruft to support that.
3370 * configure, Makefile.in, scmconfig.h.in: regenerated.
3372 Change from Thomas Morgan:
3373 * procprop.c (scm_procedure_properties): Convert the Scheme
3374 boolean returned by scm_procedure_p into a C boolean before using
3375 it as a condition for SCM_ASSERT.
3376 (scm_procedure_property): Likewise.
3378 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3379 indications of Unixness.
3382 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3384 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3386 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3388 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3389 "unknown # object" error messages.
3391 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3392 (scm_i_index) and declare it static. Add a 'direction' argument
3393 to indicate what way the search should go.
3394 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3396 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3397 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3399 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3401 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3403 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3404 to avoid clash with various scsh forks.
3406 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3408 The following two changes (ramap.c, throw.c) are motivated by the
3409 apparent unportability of forward declarations of static arrays of
3410 the form `static foo bar[];'.
3412 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3413 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3415 * throw.c (scm_throw): Moved above scm_ithrow.
3417 * options.h: Removed the extern declarations of scm_yes_sym and
3418 scm_no_sym since these are static.
3420 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3422 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3424 * Makefile.am: remove AWK=@AWK@.
3425 Add a rule for generating errnos.list.
3426 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3428 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3429 don't extract errnos, just set a variable (avoids the
3430 need to recompile error.c just because configure is run.)
3432 * unif.h: update prototypes.
3433 * unif.c (scm_uniform_array_read,write): change the offset and
3434 length arguments to start and end, for consistency.
3436 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3438 * ioext.h: update prototypes.
3439 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3440 scm_read_line_x, it's a more general procedure using an
3441 interface from scsh. read-line and read-line! are now defined
3443 Note that the new read-line trims the terminator
3444 by default, previously it was appended to the returned string. An
3445 optional argument specifies how to process the terminator (scsh
3446 compatible). For the old behaviour: (read-line port 'concat).
3447 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3448 returns a pair, but is converted to multiple values if the scsh
3451 socket.h: update prototypes.
3452 * socket.c (scm_recvfrom): for consistency with other procedures,
3453 take start and end as separate optional arguments.
3454 (scm_recv, scm_recvfrom): don't allow the second argument
3455 to be a size, only a buffer. Change the scheme names to
3456 recv! and recvfrom!. Don't return the buffer.
3458 * ioext.h, posix.h: move prototypes too.
3459 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3460 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3461 "read.h" and "unif.h".
3462 * ioext.c: include "chars.h"
3464 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3466 * dynl.c: The dynamic linking and module registration functions
3467 are now defined even when dynamic linking is not available for the
3468 host system. Some of their functionality can be done without
3469 dynamic linking; when it's really needed, they throw errors.
3471 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3473 * configure.in: Only define DYNAMIC_LINKING when one of the system
3474 dependent functions is detected.
3475 * dynl.c (scm_dynamic_func): New function to get the address of a
3476 function in a dynamic object.
3477 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3478 produced by scm_dynamic_func as the thing to call.
3480 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3482 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3483 (scm_register_module_xxx, scm_registered_modules,
3484 scm_clear_registered_modules): New functions.
3486 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3488 * symbols.c (scm_sysintern): Renamed to
3489 scm_sysintern_no_module_lookup.
3490 (scm_sysintern): New function to take the place of the old
3491 scm_sysintern. It uses the current toplevel lookup closure to give
3492 the symbol its value. This is a temporary hack to put packages
3493 like gtcltk into their own module.
3494 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3495 us whether `scm_top_level_lookup_closure_var' has been initialized
3497 * eval.c (scm_init_eval): Set it.
3499 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3501 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3502 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3504 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3506 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3507 scm_sys_dup): deleted: FD capability will be added to other
3509 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3510 scm_fd_free, fd_smob, scm_intern_fd.
3511 (scm_open): renamed from scm_sys_open. Return a port instead of
3512 an FD object. Make the mode argument optional.
3513 (scm_sys_create): deleted, it's just a special case of open.
3514 (scm_init_filesys): move interning of constants O_CREAT etc.,
3515 here (were previously using SCM_CONST_LONG macro).
3516 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3518 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3519 include "fports.h" and <stdio.h>
3520 (scm_stat, scm_select): don't support FD objects.
3522 * error.h: adjust scm_syserror_msg prototype.
3523 * error.c (scm_syserror_msg): take an extra argument for errno.
3524 Using the global value didn't always work, since it could be
3525 reset by procedure calls in the message or args arguments.
3527 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3528 I don't understand why the check was there (and what about the
3531 * strop.c (scm_string_copy): allow shared substrings to be copied.
3533 * unif.h: corresponding change to prototypes.
3534 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3535 recognize two new optional arguments: offset and length. Allow
3536 the port argument to be an integer (file descriptor, for scsh).
3537 Include <unistd.h> for "read" prototype.
3539 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3541 * socket.c: don't include filesys.h.
3543 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3545 * Makefile.am: add AWK=@AWK@ (?)
3547 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3549 Add a rule to generate errnos.c from errnos.
3550 * error.c (scm_init_error): include errnos.c.
3551 * errnos_cnvt.awk: new file, converts the list of errno codes to
3553 * errnos_get.c: new file.
3554 * errnos.default: new file, contains errnos to try if they can't
3555 be extracted from errno.h.
3556 * configure.in: if using GCC, try and extract errno codes from
3560 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3562 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3563 * Makefile.am: Made libguile into a libtool library.
3564 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3565 Set libtool_libs to indicate that libguile is a libtool library.
3566 See guile/ChangeLog for details.
3567 * .cvsignore: ignore "*.lo", the libtool library objects.
3569 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3571 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3572 use htons in getservbyport argument.
3574 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3576 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3577 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3580 * objprop.c (scm_object_property): No need to take the CDR of the
3581 value returned by scm_object_properties, since Aug 20 change.
3583 * configure.in: When checking for struct linger, #include
3584 <sys/types.h> as well as <sys/socket.h>. I've never known
3585 <sys/types.h> to cause any portability problems, and Solaris's
3586 <sys/socket.h> needs it.
3587 * configure: Rebuilt.
3589 I think the Sun compiler has chosen a perverse way to interpret
3590 ANSI declarations combined with K&R definitions. We'll
3591 appease it a little bit. But when it invades France, we fight.
3592 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3593 * print.h (scm_iprlist): Here too.
3594 * numbers.c (scm_divbigdig): Change definition to match
3595 declaration in numbers.h.
3596 * unif.c (scm_makflo): Change definition to match declaration in
3599 * init.c (scm_boot_guile): Don't return the value of
3600 scm_boot_guile_1. This function doesn't return a value;
3601 scm_boot_guile_1 doesn't return a value (or return at all).
3603 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3606 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3607 compile. I have a feeling this function is a bad idea anyway ---
3608 one should always test for features, not systems.
3610 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3611 semicolons. Only pure luck kept this from being noticed earlier.
3613 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3615 * socket.c (scm_recvfrom): Added missing semicolon.
3617 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3619 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3620 the buffer and start and end positions for scsh networking
3623 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3625 * configure.in: Revert previous change to this file; the problem
3626 is due to transient automake weirdness.
3627 * configure: Rebuilt.
3629 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3630 PLUGIN/guile.libs. configure generates the latter from the former.
3631 * Makefile.in: Rebuilt.
3633 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3634 need this if we install scripts, like guile-snarf.
3635 * configure: Rebuilt.
3637 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3639 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3641 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3643 * socket.c (scm_addr_vector): fix faulty scm_listify.
3645 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3647 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3648 style block comment is no longer considered an error.
3650 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3652 * PLUGIN/guile.libs.in: New file.
3653 * PLUGIN/guile.libs: Removed from repository.
3654 * configure.in: Create PLUGIN/guile.libs from
3655 PLUGIN/guile.libs.in. This is for including additonal libraries
3656 needed for dynamic linking.
3657 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3658 instead of PLUGIN/guile.libs.
3660 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3662 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3664 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3665 occurrences of the given element from the list, not just the
3666 first. This is how the Emacs Lisp functions behave, how the
3667 analogous Common Lisp functions behave, and (I believe) how the
3668 older Maclisp functions worked. I realize that this change may
3669 break code, but it seemed better to break it before the Guile
3672 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3673 Their prototypes were already present in gc.h, but they weren't
3675 (scm_init_storage): Initialize scm_protects.
3676 * root.c (scm_protects): New element of scm_sys_protects.
3678 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3680 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3682 * libguile.h: Added #include "libguile/net_db.h".
3684 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3685 30 change. That file is only meant for communication between the
3686 configuration process and load.c. If code linked against libguile
3687 wants to get at the paths mentioned in libpath.h, it can call
3688 functions declared in load.h.
3690 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3692 * libguile.h: Removed #include "libguile/fdsocket.h"
3694 * net_db.c: Added #include <sys/socket.h>.
3696 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3698 * filesys.c (scm_input_waiting_p): use select in preference to
3699 FIONREAD, since the latter doesn't detect EOF.
3700 Throw error if neither select nor FIONREAD available.
3702 * socket.c (scm_connect): take a port, not a fd object.
3703 (scm_fill_sockaddr): throw an error if fam is not recognised.
3704 (scm_bind): use scm_fill_sockaddr.
3705 (scm_listen): take a port, not a fd object.
3706 (scm_accept): take and return a port. return #f in the car if
3707 address can't be got
3708 (scm_sock_fd_to_port): new procedure.
3709 (scm_socket): use scm_sock_fd_to_port.
3710 (scm_addr_vector): throw error if unrecognised address type.
3711 take an extra argument with the calling procedure name.
3712 (scm_getsockname): take a port. return #f if address can't be got.
3713 (scm_getpeername): take a port. return #f if address can't be got.
3714 (scm_recvfrom): take a port. return #f for address component if can't
3716 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3717 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3719 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3721 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3722 use separate data pointers, to allow them to be designed
3723 independently and reused.
3724 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3725 Renamed from catch_body, catch_handler, and uncaught_throw; made
3727 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3729 (scm_catch): Use the above.
3730 (scm_throw): Don't bother printing a message for an uncaught
3731 throw; we establish a default handler in init.
3732 * throw.h (scm_internal_catch): Prototype updated.
3733 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3735 (struct scm_body_thunk_data): New structure, used as data
3736 argument to scm_body_thunk.
3737 * init.c (struct main_func_closure): New structure, packaging up
3738 the data to pass to the user's main function.
3739 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3740 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3741 scm_internal_catch to establish a catch-all handler, using
3742 scm_handle_by_message. This replaces the special-case code in
3744 (invoke_main_func): Body function for scm_internal_catch; invoke
3745 the user's main function, using the main_func_closure pointer to
3746 decide what to pass it.
3747 * root.c (struct cwdr_body_data): Remove handler_proc member.
3748 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3749 (cwdr_handler): Removed.
3751 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3753 * socket.h (SCM_P): update bind prototype.
3754 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3755 include "feature.h".
3756 (scm_socket): return a port, not a file descriptor object.
3757 include "fports.h" and <unistd.h>
3758 (scm_bind): take a port, not a file descriptor object.
3759 take an extra argument for address args.
3761 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3762 INADDR_NONE, INADDR_LOOPBACK.
3764 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3766 * init.c: include net_db.h and not fdsocket.h.
3767 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3769 * Makefile.am: corresponding changes.
3770 * socket.h: renamed from fdsocket.h, fix names.
3771 * net_db.h: renamed from socket.h, fix names.
3772 * socket.c: renamed from fdsocket.c.
3773 remove _sys from procedure names.
3774 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3775 add "socket" to features list.
3776 * net_db.c: renamed from socket.c.
3777 remove _sys from procedure names.
3778 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3779 add "net-db" to features list.
3780 include "net_db.h". don't include <sys/socket.h> or
3783 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3785 * tags.h (scm_tags): Removed comma at end of last enumerator.
3787 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3789 Don't use GCC extensions to allocate space for debugging frames.
3790 (Here he goes again! Why do we put up with this?!)
3791 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3792 an scm_debug_info structure, not an in-line array of them. Add
3793 'info' member, to say how many vect elements we've used, for eval
3795 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3796 a new variable debug_info_end to mark the end of vect, instead of
3797 the address of the 'info' pointer itself.
3798 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3799 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3800 (SCM_APPLY): Explicitly allocate space for debug.vect.
3801 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3802 * stacks.c: Adjusted for new debug frame structure.
3803 (RELOC_INFO, RELOC_FRAME): New macros.
3804 (stack_depth, read_frames): Use them, and new scm_debug_frame
3805 element 'info', instead of magically knowing that eval frames have
3806 an info pointer sitting after vect.
3807 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3809 (scm_init_stacks): Formatting tweaks.
3811 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3813 Give GCC more control flow information, so it can be sure that
3814 variables aren't used uninitialized.
3815 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3816 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3817 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3818 scm_misc_error): Tell GCC that these functions never return.
3819 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3820 out the field type, call abort if SCM_ASSERT returns, to placate
3822 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3823 scm_wta ever returns. We can't handle this case anyway, and this
3824 gives the optimizer more information.
3825 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3826 scm_wta ever returns.
3828 In some cases, the code is fine, but GCC isn't smart enough to
3829 figure that out; this usually happens when one variable is only
3830 initialized and used when a particular condition holds true, and
3831 we know that condition will never change within a given invocation
3832 of the function. In this case, we simply initialize the variables
3833 to placate the compiler, hopefully to a value which will cause a
3834 crash if it is ever actually used.
3835 * print.c (scm_iprin1): Initialize mw_pos.
3836 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3837 * throw.c (scm_ithrow): Initialize dynpair.
3838 * unif.c (scm_uniform_vector_ref): Initialize cra.
3839 * struct.c (init_struct): Initialize prot.
3840 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3842 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3843 if EXPR contains no expressions.
3845 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3847 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3848 cause an infinite loop (???). So much for the algebraic
3849 equivalency of variable-sized arrays and alloca...
3851 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3853 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3854 a SCM boolean, not a C boolean.
3856 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3858 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3859 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3860 rules for raising scm_mtrigger. Previously, unfortunate but not
3861 unlikely circumstances could result in almost constant invokation
3862 of the gc. Now, this situations should be less likely, but they
3863 are not prevented completely.
3865 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3867 * numbers.c (scm_fuck): Procedure removed; looks like old test
3869 * numbers.h: Prototype removed.
3871 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3873 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3874 array to a pointer, to match my Nov 21 change in eval.c.
3876 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3878 * libguile.h: Added #include "libguile/backtrace.h", #include
3879 "libguile/stacks.h".
3881 * strings.c (scm_string scm_make_string scm_string_ref
3882 scm_string_set_x scm_string_equal_p scm_string_append):
3883 Bugfix according to scm patch from Aubrey Jaffer:
3884 Corrected long-standing
3885 (not (eqv? (integer->char 128)
3886 (string-ref (make-string 1 (integer->char 128)) 0)))
3887 bug found by John Kozak <jk@noontide.demon.co.uk>.
3889 * strports.c, strports.h: Make scm_eval_0str return the value of
3890 the last expression evaluated (previously, it returned void).
3892 * strports.c, strports.h: New function: scm_read_0str. Does what
3895 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3897 * simpos.c (scm_getenv): return #f if string can't be found in the
3898 environment instead of throwing an exception, for compatibility
3899 with numerous other systems.
3901 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3903 * Makefile.am (.c.x): Use guile-snarf.
3904 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3906 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3908 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3910 * backtrace.c (scm_display_error_message): Made non-static, and
3911 renamed from display_error_message.
3912 * backtrace.h (scm_display_error_message): Added extern decl.
3913 * throw.c (uncaught_throw): Use it to display the error message.
3915 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3917 * inet_aton.c: Use #if 0, not #ifdef 0.
3919 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3921 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3922 to convert the returned value.
3923 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3924 the offset argument.
3926 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3928 Add new interface to catch/throw, usable from C as well as
3930 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3931 (scm_internal_catch): New function, replaces...
3932 (scm_catch_apply): Deleted.
3933 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3934 mechanism which is a bit more code, but can be used nicely from C
3935 and implement the Scheme semantics as well.
3936 (scm_internal_catch): This is the replacement; it's named after
3937 the analogous function in Emacs.
3938 (scm_catch): Reimplemented in terms of the above.
3939 (struct catch_body_data, catch_body, catch_handler): New
3940 functions, used by scm_catch.
3941 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3942 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3943 support for new cwdr.
3945 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3948 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3950 * acconfig.h: Added DYNAMIC_LINKING symbol.
3951 * configure.in: Add option and checks for dynamic linking.
3952 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3953 dynl.h: New files for dynamic linking support.
3954 * Makefile.am (libguile_a_SOURCES):
3956 (modinclude_HEADERS): Added "dynl.h".
3957 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3959 * init.c (scm_boot_guile_1): Call
3960 scm_init_dynamic_linking to initialize dynamic linking support.
3962 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3964 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3965 (as we Schemers say). It needs to be global, so that I can tweak
3966 it for the proper operation of unexec.
3967 (scm_boot_guile_1_live): New variable, see above.
3969 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3971 * guile-snarf.sh: Removed.
3972 * PLUGIN/guile.libs: Added dependency for -lm.
3973 * acinclude.m4: Renamed from aclocal.m4.
3974 * PLUGIN/greet: Removed.
3975 * Makefile.am, aclocal.m4: New files.
3976 * configure.in: Updated for Automake.
3978 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3980 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3981 and not top_level_lookup_thunk_var.
3983 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3985 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3987 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3989 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3990 Scheme function, instead of syntax. Single argument is now a
3993 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3995 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3996 scm_ra_divide): Properly terminate statements passed as arguments
3997 to IVDEP macros. (Thanks to Bernard Urban.)
3999 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4000 with non-constant sizes. (Thanks to Bernard Urban.)
4002 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4004 It's an "eval closure", not an "eval thunk." A thunk is a
4005 function of no arguments.
4006 * root.h (struct scm_root_state): Renamed
4007 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4008 (scm_top_level_lookup_closure_var): Renamed from
4009 scm_top_level_lookup_thunk_var.
4010 * root.c (mark_root): Uses changed.
4011 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4012 * init.c (scm_start_stack): Uses changed.
4013 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4014 Change scheme-visible name to *top-level-lookup-closure* from
4015 *top-level-lookup-thunk*.
4017 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4019 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4020 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4022 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4024 * gc.c (struct scm_heap_seg_data): Doc fixes.
4026 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4027 sweeping. Then, prepend each segment's free cells to its
4028 freelist, rather than wiping out the old value. (Thanks to Marius
4031 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4032 scm_check_freelist, scm_debug_newcell): New functions and
4033 variables, for debugging freelist problems.
4034 * pairs.h (SCM_NEWCELL): New debugging version added.
4035 * gc.h (scm_debug_newcell): Added extern declaration, used by
4036 debugging version of SCM_NEWCELL.
4038 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4040 On some systems <libc.h> conflicts with <unistd.h>, and should not
4041 be #included at all.
4042 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4043 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4044 * configure.in: Call it.
4045 * posix.c, filesys.c: Use its results to decide whether or not to
4047 * configure, scmconfig.h.in: Rebuilt with autoconf and
4050 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4052 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4053 pointer to the stdio stream before calling scm_setbuf0, so the
4054 latter will be able to retrieve it. I'm surprised this didn't
4055 segfault earlier. (Thanks to Christopher Lee.)
4057 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4059 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4062 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4064 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4065 number of stack narrowing specifier pairs. The first specifier in
4066 a pair controls inner border, the second the outer border. A
4067 number means cut that number of frames, a procedure object means
4068 cut until that object is found in operator position in a frame.
4070 * root.c (cwdr): Bugfix.
4072 * read.c: Recording of positions disabled by default.
4074 * procs.c (scm_closure_p): New function.
4076 * posix.c (scm_tmpnam): New function.
4078 * load.c: Added #include "throw.h".
4079 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4082 * load.c, load.h (scm_read_and_eval_x): New function.
4084 * eval.c: Renamed debug option "deval" to "debug".
4086 (scm_eval_x): `eval!' is no longer accessible from the scheme
4087 level. Motivation: We can't allow operations which introduce
4088 glocs into the scheme level. Guile's type system can't handle
4089 these as data. Use `eval' or `read-and-eval!' as replacement.
4091 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4092 SCM_CONSP since this is a macro!; Set vframe.prev to
4093 scm_last_debug_frame instead of 0. In this way we can look
4094 "above" the virtual start stack frame if we wish.
4095 (scm_debug_hang): New function: Useful for debugging Guile in
4096 certain tricky situations. Will probably be removed later...
4098 * debug.h: Changed semantics of debug option "backtrace". This
4099 option now only indicates whether we want automatic backtrace at
4102 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4104 * ports.c: #include "filesys.h"
4105 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4107 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4108 Motivation: This is system specific code which is related to file
4109 I/O. It also may use select. Added code by Gary Houston to
4110 detect presence of character in stdio buffers.
4112 * libguile.h: #include "libguile/libpath.h"
4114 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4115 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4116 SCM_SITE_DIR; Install libpath.h among the other include files.
4118 * load.c, load.h (scm_sys_package_data_dir): New function.
4120 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4122 * stacks.h: Bugfix: Don't use tail-array length field as stack
4123 length field! This screwed GC.
4125 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4127 * _scm.h: Added #ifndef around definition of macros min and max.
4129 * __scm.h: Added hooks for threads to plugin to in ints protection
4130 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4131 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4132 the main code in these macros duplicated and spread over multiple
4133 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4134 SCM_THREAD_SWITCHING_CODE.
4136 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4138 * snarf.h: New file.
4139 * guile-snarf.sh: New file.
4140 * Makefile.in (inner_h_files): Added snarf.h
4141 (ancillary, install, uninstall, distclean): Added actions for
4143 (.c.x): Use guile-snarf.
4144 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4145 (gen_c_files): Note that these depend on guile-snarf.
4146 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4147 now in "snarf.h". Added #include "snarf.h" to get them.
4148 * libguile.h: Added #include "snarf.h".
4149 (Patches applied and tweaked by Jim Blandy.)
4151 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4153 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4154 standards suggest against providing prototypes for system
4155 functions. Thanks to Greg Troxel.
4157 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4159 * strports.c (scm_eval_0str): New function.
4160 #include "read.h", to get prototype for scm_read.
4161 * Makefile.in (strports.o): Update dependencies.
4162 * strports.h: New prototype.
4164 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4165 scheme name from "int?" to "integer?". It seems to do the job.
4166 * numbers.h: Rename prototype too.
4167 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4170 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4171 scm_num_eq_p): Rename these according to R4RS conventions: call
4172 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4173 to making libguile R4RS compliant without ice-9...
4175 * load.c (scm_sys_search_load_path): Search for files under all
4176 extensions listed in the %load-extensions variable. If FILENAME
4177 is absolute, return it unchanged, without searching the load path.
4178 (scm_loc_load_extensions): New variable, pointing to
4179 %load-extensions' value cell.
4180 (scm_init_load): Initialize it, and the value it points to.
4181 (scm_primitive_load_path): Improve error reporting.
4183 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4184 of new Scheme variable %load-hook.
4185 (scm_primitive_load): Apply %load-hook to filename.
4187 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4189 * configure.in: add tests for figuring out whether buffered data
4190 is available in a FILE structure, which is needed by char-ready.
4192 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4195 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4196 exceptions using misc_error instead of syserror. It seems a bit
4197 odd to throw an exception if a string can't be found in the
4198 environment, but it's consistent with open-file, stat etc.
4199 (simpos.h): remove sys_ from getenv.
4201 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4202 occurs, throw an error instead of returning errno. Return value
4204 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4206 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4208 * filesys.c (scm_stat2scm): derive file type and permissions from
4209 the stat mode and append them to the returned vector.
4210 There isn't much overhead in doing this and it avoids the need to
4211 work with S_IRUSR et al. in Scheme.
4212 Define symbols scm_sym_regular etc.
4213 (scm_init_filesys): don't intern S_IRUSR etc.
4215 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4216 and s_primitive_load_path.
4218 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4220 * error.h: don't declare error symbols. prototype for scm_misc_error.
4222 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4225 * error.c: use SCM_SYMBOL to set up error keys.
4226 scm_misc_error: new procedure.
4228 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4230 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4231 between `#!' and `!#' is ignored.
4232 (skip_scsh_block_comment): New function.
4234 * feature.c (scm_set_program_arguments): New argument, FIRST.
4235 * feature.h: Update prototype.
4236 * init.c (scm_boot_guile_1): Pass new argument to
4237 scm_set_program_arguments.
4239 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4241 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4242 (scm_boot_guile): Call scm_set_program_arguments here, later than
4243 the old initialization.
4245 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4246 initialization procedure.
4247 - Delete in, out, err arguments; there are other perfectly good
4248 ways to override these when desired.
4249 - Delete result argument; this function shouldn't ever return.
4250 - Rename init_func argument to main_func, for less confusion.
4251 - Delete boot_cmd argument; main_func is more general.
4252 -Add 'closure' argument, to help people pass data to main_func
4253 without resorting to global variables.
4254 - Abort if reentered; don't bother returning an error code.
4255 - Call scm_init_standard_ports to set up the default/current
4256 standard ports; no need to pass them to scm_start_stack.
4257 - Remove code to evaluate the boot_cmd, and start the repl; let
4258 the user do something like that in main_func if they want.
4259 - Remove code to package up a return value; main_func can do any
4261 - Call exit (0), instead of returning.
4262 (scm_start_stack): Don't initialize the I/O ports here; that's
4263 weird. Delete in, out, err arguments. Move guts to
4264 scm_init_standard_ports, scm_stdio_to_port.
4265 (scm_init_standard_ports): New function, to set up current and
4266 default standard ports.
4267 (scm_start_stack, scm_restart_stack): Make these static.
4268 * init.h (scm_boot_guile): Adjust declaration.
4269 (scm_start_stack, scm_restart_stack): Remove externally
4270 visible declarations for these.
4271 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4273 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4274 written out several times in scm_start_stack.
4275 * fports.h: New declaration for the above.
4277 * feature.c (scm_set_program_arguments): New function.
4278 * feature.h: New declaration for the above.
4280 * ports.c: Formatting tweak.
4282 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4284 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4285 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4286 for obtaining the address of a car or cdr field. Motivation:
4287 &SCM_CXR make assumptions about the internal structure of the
4290 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4291 Motivation: see SCM_CXRLOC.
4293 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4294 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4295 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4296 Motivation: Safer use. Some other macros are defined in terms of
4297 these operations. If these are defined using the SCM_SETCXR
4298 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4299 to inefficiency and an <e1> with side-effects could potentially
4300 break. Also, these particular operations are heavily utilized in
4301 the garbage collector. In unoptimized code there will be a
4304 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4305 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4306 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4307 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4308 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4309 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4310 vports.c: Cleaned up use of pairs: Don't make any special
4311 assumptions about the internal structure of selectors and
4312 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4313 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4314 (Among other things, this change makes it easier to build Guile
4315 with certain compilers which have problems with casted lvalues.)
4317 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4319 * stacks.c: Improve selection of relevant stack frames when making
4320 a stack object. Introduce one level of indirection in the stack
4321 object to make it possible to "narrow" to a certain region of the
4322 stack. This facilitates making use of more clever algorithms (not
4323 implemented) for selecting relevant frames and gives a cleaner
4324 design since selection of frames can be done independently of
4325 extraction of frames from the real stack.
4326 (scm_stack_id): Also take #t as argument which means look at
4329 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4330 Turn n_tail into an integer directly representing current number
4331 of frames in stack. Add field tail.
4333 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4335 * debug.c (scm_make_memoized): Made it available at scheme level.
4336 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4337 SCM_NIMP before applying heavier predicates in argument checking.
4338 (scm_local_eval): Also take memoized object as argument.
4340 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4341 aren't created with zero length, but should such a strange
4342 creature suddenly turn up...
4344 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4346 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4347 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4349 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4351 * variable.c (scm_make_variable): Make the name hint optional, as
4353 (anonymous_variable_sym): Renamed from variable_sym. All uses
4356 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4357 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4358 of scm_primitive_load_path was also changed to
4359 "primitive-load-path", from "%try-load-path". Callers changed.
4360 We'd like to respect the convention that a function named
4361 "try-mumble" should behave just like the function called "mumble",
4362 but return #f instead of signalling some error.
4363 * load.h: Rename prototypes.
4365 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4367 * print.c (make_print_state, grow_print_state), print.h: Modified
4368 the print state representation: Don't use a tail array for
4369 recording of circular references. Resizing of the print state
4370 structure invalidates the print state pointer. To avoid passing
4371 around an indirect print state reference to all printing
4372 functions, we instead let the print state reference a resizable
4375 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4377 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4378 Don't crash when passed an improper list terminated by a
4379 non-immediate value.
4381 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4383 Allocate data for structures on an eight-byte boundary, as
4384 required by the tagging system.
4385 * struct.c (alloc_struct): New function.
4386 (scm_make_struct, scm_make_vtable_vtable): Call it.
4387 * struct.h (scm_struct_n_extra_words): Bump to 3.
4388 (scm_struct_i_ptr): New "field".
4389 * gc.c (scm_gc_sweep): When we need to free the data, use the
4390 information stored by alloc_struct to find the beginning of the
4391 block allocated to the structure, so we can free it.
4393 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4395 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4398 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4399 (scm_debug_info): New member: id.
4401 * stacks.c: Stacks are now represented as structs; Stacks have an
4402 id given to them by `start-stack'.
4403 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4405 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4406 Changed stack representation.
4408 * debug.c (scm_procedure_name): Try procedure property `name' for
4409 compiled closures aswell.
4411 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4413 * eval.c: scm_i_name moved to gsubr.c
4414 (scm_m_define): Record names of all kinds of procedure
4415 objects. (Earlier, only closures were recorded.)
4417 * procprop.h: Added declaration of scm_i_name.
4419 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4420 (scm_make_gsubr): Record names of compiled closures.
4422 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4424 * debug.c, debug.h: Removed obsolete code.
4426 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4427 stacks.c: Renamed regs --> scm_contregs.
4429 * print.c (scm_free_print_state): Cleanup print state before
4430 returning it to pool. It is better to do it here than in
4431 scm_prin1 since scm_prin1 is called often.
4433 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4434 s_set_source_property_x): Check that first argument is a pair or a
4437 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4438 scm_i_line, scm_i_column and scm_i_breakpoint global.
4440 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4441 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4444 * debug.h: Added debug object smob declaration and macro
4447 * configure.in: Build with backtrace.o and stacks.o if debug
4450 * Makefile.in: Added entries for new files: backtrace.c,
4451 backtrace.h, stacks.c and stacks.h.
4453 * symbols.c (scm_sym2ovcell): Fixed documentation.
4455 * _scm.h (min, max): Added.
4457 * async.c: Moved `min' macro to _scm.h.
4459 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4460 SCM_BACKTRACE_INDENT.
4462 * eval.c: Added new debug options `maxdepth' and `indent'.
4464 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4466 * print.h: Added selector SCM_PRINT_STATE.
4468 * print.c: New functions: scm_make_print_state,
4469 scm_free_print_state.
4471 * print.h: Added declarations for scm_make_print_state,
4472 scm_free_print_state.
4474 * debug.c (scm_m_start_stack): New acro.
4476 * debug.h: Small cleanup.
4478 * init.c (scm_boot_guile_1): Moved scm_init_debug below

4501 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
4502 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
4503 declare functions with prototypes. (Patch thanks to Marius
4506 More prototype-related changes from Marius Vollmer:
4507 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4508 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4509 * ports.h (ptobfuns): Added prototypes. This means some casting in
4511 * fports.c: Added casts for initializations, since the functions
4512 are defined to take FILE * as their stream argument, not SCM.
4513 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4514 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4515 to `char *str_data' to conform to prototype.
4517 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4519 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4521 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4523 * stime.c, stime.h: use SCM_P method.
4525 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4527 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4528 be given at least two arguments. Insist that lst's last element
4529 be a list, but don't make any requirements of its predecessors.
4531 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4533 * eval.c (scm_nconc2last): Revert last change; there seems to be
4534 other stuff going on here.
4536 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4538 * eval.c (scm_nconc2last): Make sure that each element of lst
4539 (which is a list of argument lists, except for the tail) is a
4540 proper list, i.e., finite and terminated by '().
4542 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4544 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4547 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4548 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4551 * vectors.c (scm_make_vector): Fill vectors with the undefined
4552 value, to help make Guile Scheme code more portable to other
4555 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4556 * symbols.h, tags.h: Doc fixes.
4558 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4560 * async.c (scm_take_signal): Doc fixes.
4562 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4564 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4565 want to subtract it from the modulus; we just want to leave it
4568 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4570 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4573 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4575 * throw.c (scm_catch_apply): Finished implementation of
4578 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4580 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4582 (scm_init_filesys): set "i/o-extensions" feature.
4585 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4587 * Makefile.in (root.o): Correct dependencies.
4589 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4591 * Makefile.in: Added dependency entry for root.o.
4593 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4594 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4596 * init.c (scm_start_stack): Set initial root continuation number
4599 * procs.c: New function: scm_thunk_p.
4601 * procs.h: Added declarations of scm_thunk_p.
4603 * root.c: Renamed `call-with-new-root' -->
4604 `call-with-dynamic-root'.
4605 (cwdr): Removed allocation of new root state. This should be done
4606 separately by use of scm_make_root.
4607 (scm_apply_with_dynamic_root): New function: Does what it
4608 sounds like. Needed when spawning threads.
4610 * root.h: Added member last_debug_frame to root state.
4611 Added #include "libguile/debug.h"
4613 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4614 arguments. The motivation is that code in root.c needs catch
4615 functionality, and we want to avoid code duplication.
4616 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4617 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4618 handlers that run without popping the stack into the dynwind
4621 * throw.h: Added prototypes for scm_catch_apply and
4624 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4626 * root.h (scm_root, scm_set_root): Decouple thread support details
4627 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4628 SCM_SET_THREAD_LOCAL_DATA.
4630 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4631 and tortoise scanning loop.
4633 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4635 * Makefile.in: Rebuild dependencies.
4637 * libguile.h: #include "libguile/print.h" before "smob.h", since
4638 the latter uses the print_state structure.
4640 * throw.c (scm_ithrow): Use the correct variable when checking to
4641 see if a given element of scm_dynwinds is a valid catch.
4643 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4644 structure, abort; don't just silently ignore the garbage.
4646 * _scm.h: #include "print.h" here, since it seems to be used just
4648 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4649 strports.c, unif.h: Don't #include "print.h".
4651 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4653 * feature.h (scm_loc_features): Removed external declaration.
4654 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4656 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4658 * feature.c (scm_init_feature): Added threads feature (needs to be
4659 initialized here, since features doesn't exist when
4660 scm_init_threads is called).
4662 * libguile.h: Added #include "libguile/../threads/threads.h".
4663 (This is a kludge to get thread support working. This should be
4666 * configure.in, acconfig.h: Added flags for thread support.
4668 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4671 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4672 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4675 * _scm.h: Added conditional #include "threads.h"
4677 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4678 SCM_THREADS_SWITCHING_CODE.
4680 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4681 allocate the basic dynamic root object.
4682 (scm_boot_guile): Added call to scm_init_root.
4684 * root.c, root.h: Added root smob.
4685 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4686 functions: Implements dynamic roots mostly according to spec in
4687 SCM manual. Main difference is that the second argument is a
4688 throw handler rather than an error "thunk".
4690 * root.h: Added declaration of scm_init_root.
4692 * root.c: Added #include "genio.h", #include "smob.h", #include
4693 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4695 (scm_init_root): Added #include "root.x".
4697 * throw.c: Added #include "stackchk.h"
4698 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4699 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4700 can be used in scm_call_with_new_root; Added reenabling of stack
4701 checking when catching a throw.
4703 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4705 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4707 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4708 element is not found, as per R4RS.
4710 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4712 * list.c: Doc fixes throughout.
4714 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4716 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4717 declare the char * to be const. Avoids a warning in rgx.c.
4719 * ports.h: spelling fix.
4721 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4724 * load.c (scm_sys_try_load_path): throw an error if file not found
4725 (like it says it in NEWS).
4727 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4729 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4730 PROPS slot to '(), not #f; it's an empty alist.
4732 * throw.h, throw.c: Use SCM_P instead of #if hair.
4734 Remove special support for uncaught throws; see throw.c for
4736 * throw.c (uncaught_throw): New function.
4737 (scm_ithrow): Call uncaught_throw if we don't find a throw
4738 target; don't mess with scm_bad_throw_vcell.
4739 (scm_bad_throw_vcell): Variable deleted.
4740 (scm_init_throw): Don't initialize it.
4742 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4745 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4747 * numbers.c (scm_istr2int): If the number is short (as most
4748 numbers are), just call scm_small_istr2int to deal with it.
4749 (scm_small_istr2int): New function, created by un-#ifdefing the
4750 non-bignum version of scm_istr2int and renaming it.
4752 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4754 * load.c (scm_sys_try_load): don't check whether value returned
4755 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4756 Change the Scheme name from %try-load to primitive-load.
4758 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4759 Can avoid passing a message, allowing it to be derived in the
4760 error handler (e.g., if we want to throw to the key both from
4763 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4765 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4766 references now have a new appearance which is more compact and
4767 also gives a clue about what the target of the reference is.
4768 By setting parameters in the print state, more fancy printing can
4769 be achieved. This is used by the (not yet commited) backtrace
4772 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4774 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4777 * print.c: Added #include "struct.h". Removed function
4780 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4781 scm_iprin1. Removed prototype for scm_prlist.
4783 * arbiters.c (prinarb),
4784 async.c (print_async),
4785 debug.c (prindebugobj, prinmemoized),
4786 eval.c (prinprom, prinmacro),
4787 filesys.c (scm_fd_print, scm_dir_print),
4789 mallocs.c (prinmalloc),
4790 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4791 smob.h (scm_smobfuns),
4792 srcprop.c (prinsrcprops),
4794 unif.c, unif.h (scm_raprin1, rapr1),
4795 variable.c (prin_var): Changed argument `int writing' to
4796 `scm_print_state *pstate'.
4798 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4799 that it will be called before scm_init_print.
4801 * print.c (scm_prin1): Print states are now allocated when calling
4802 scm_prin1 and then passed around to all printing functions as an
4803 argument. A cache `print_state_pool' enables reuse of print
4805 (scm_make_print_state): New function.
4806 (scm_iprin1): Adaption to print states.
4807 (scm_iprlist): An initial "hare and tortoise" scan brings down
4808 time complexity to O (depth * N). (Better time complexity will be
4809 achieved when the printing code is completely rewritten.)
4811 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4813 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4814 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4815 it gets done whether or not the cache variable has a value.
4817 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4819 Distinguish #f and ().
4820 * __scm.h: #undef SICP.
4821 * pairs.h (SCM_EOL): Delete this definition, equating it with
4823 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4824 the value it used to have. Doc fixes, too.
4826 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4828 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4829 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4830 Lord's implementation of structs, allowing for tail arrays as
4831 described in the manual. Also fixed some bugs. (Both the interface
4832 and the implementation should be improved.)
4834 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4836 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4837 People who whish to see the source can do `(print-enable 'source)'.
4838 Removed #ifdef DEBUG_EXTENSIONS.
4840 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4842 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4843 integer (assuming for now accepting an integer is a good thing).
4845 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4846 %S will be used instead for write'ing arguments.
4848 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4849 asserts. fix a few other asserts.
4850 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4851 scm_uniform_vector_ref, scm_array_set_x,
4852 scm_dimensions_to_unform_array): change args in
4853 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4854 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4855 scm_substring_fill_x): likewise.
4856 gsubr.c (scm_gsubr_apply): likewise.
4857 eval.c (SCM_APPLY): likewise.
4859 * eval.c (4 places): replace scm_everr with lgh_error or
4862 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4863 scm_memory_error): new procedures.
4864 scm_everr: deleted. can use scm_wta, dropping first two args.
4865 scm_error: convert NULL subr to SCM_BOOL_F.
4867 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4870 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4873 * error.c, error.h: new error keys: scm_arg_type_key,
4874 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4876 scm_wta: reimplement using lgh_error instead of scm_everr.
4878 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4880 * gdbint.c: scm_lread now has one more argument.
4882 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4883 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4884 loading source from non-file ports, which, e. g., happens when
4885 using the Emacs interface).
4887 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4890 * read.c: Added code for recording of positions of source code
4891 expressions; New functions: recsexpr, scm_lreadrecparen;
4892 _scm_make_srcprops --> scm_make_srcprops
4893 (scm_flush_ws): Removed updating of positions counters. This work
4894 is already done by scm_gen_getc
4896 * read.h: Added prototype for scm_lreadrecparen
4898 * print.c: Added #include "alist.h"
4900 * eval.c: Added #include "hash.h"

4908 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4909 --> scm_make_srcprops
4911 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4912 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4913 function calls in the definition of the whash access macros.
4915 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4917 * init.c (scm_boot_guile): Add level of indirection to
4918 scm_boot_guile_1() to ensure that stack base pointer is properly
4919 initialized. There was no guarantee that variable i was the
4920 highest/lowest variable on stack (i.e. the call frame of
4921 scm_boot_guile was not completely protected from gc).
4923 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4925 * ports.h (scm_port_table): put back file_name, it will be used to
4926 support debugging. Undo related changes in fports.c, ioext.c,
4929 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4931 * ports.h (scm_port_table): remove file_name member for now, it seems
4933 * fports.c (scm_open_file): don't set file_name in PTAB.
4934 (prinfport): don't use file_name in PTAB.
4935 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4936 * ports.c (scm_add_to_port_table): don't intialize file_name.
4937 (scm_port_file_name): remove for now.
4938 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4940 * fports.h (scm_mkfile): prototype deleted.
4941 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4943 * debug.c, unif.c: use scm_out_of_range instead of
4944 wta for range errors (ASSERT still needs work).
4946 * error.c, error.h (scm_out_of_range): new procedure.
4948 * error.c, error.h (scm_out_of_range_key): new key.
4950 * posix.c (scm_sync): #else was missing.
4952 * error.c, error.h: append _key to names scm_num_overflow and
4955 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4956 of consing an empty list.
4957 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4958 of macros, saves code and string space.
4959 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4960 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4961 lower case. Rename scm_syserror_m to scm_syserror_msg.
4962 error.h: prototypes for new procedures.
4964 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4966 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4968 * error.c, error.h: setup scm_num_overflow key.
4970 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4971 Remove definition of SCM_OVSCM_FLOW.
4973 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4975 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4976 explicit message and args.
4978 * error.c, error.h, __scm.h: change system_error_sym to
4981 * error.c (system_error_sym): remove leading %% from the Scheme name
4984 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4986 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4988 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4989 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4990 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4991 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4992 renamed. (These were introduced by unsupervised name
4995 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4997 * print.c: Added code for detection of circular references during
4998 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4999 a hook for printing of closures (accessible via print options).
5000 This leads to a split of calls to scm_iprin1 into two classes:
5001 elementary print operations (e. g. the code which prints a smob)
5002 still use scm_iprin1 while top level calls (like scm_display) use
5003 scm_prin1. scm_prin1 begins by clearing the data structure used
5004 to record reference information.
5006 * print.h: Added declarations of scm_prin1 and scm_prlist.
5008 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5010 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5012 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5014 * error.c (err_head): scm_iprin1 --> scm_prin1
5016 * debug.c: Adjusted header comment.
5020 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5022 * strerror.c: Doc fix.
5024 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5026 * gdbint.c (gdb_read): Now possible to run during GC.
5027 (unmark_port, remark_port): New functions.
5029 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5031 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5032 of allocating a new string object. Also, increase size by
5033 the factor 2 instead of 1.5.
5035 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5037 * __scm.h (SCM_P): Corrected to run under traditional C.
5039 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5042 * async.c: Calls to scm_sysintern corrected.
5044 * async.h (scm_async_clock): Redundant declaration removed.
5046 * continuations.c (scm_dynthrow): Redundant declaration removed.
5048 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5049 Definition typos corrected.
5051 * debug.h: Missing declarations of functions in debug.c added
5054 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5055 Missing declarations to functions in eval.c added.
5057 * filesys.c: Possibly uninitialized variable rv.
5059 * gc.h (scm_object_addr, scm_unhash_name): Missing
5060 declarations of functions defined in gc.c added.
5062 * genio.c: Possible typos str_data -> wstr_data. ???
5064 * genio.c: Possibly unintended shadowing of local variable
5065 `int c' (gotos out of scope of inner `c'). ???
5067 * init.c: Uninitialized `SCM last' may be used.
5069 * ioext.h: (scm_sys_isatty_p): Typo.
5071 * list.h (scm_list_head): Missing prototype for function in
5074 * numbers.c (scm_two_doubles): Changed from extern to static
5075 (is used only within numbers.c).
5077 * numbers.h: Repeated declarations removed.
5079 * ports.h (scm_close_all_ports_except): Declaration for the
5080 function defined in ports.c added.
5082 * posix.h: Missing declarations added.
5084 * procs.h (scm_make_subr_opt): Missing declaration added.
5086 * socket.h (scm_sys_gethost): Missing declaration added.
5088 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5090 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5091 Missing declarations added.
5093 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5095 * struct.c: Uninitialized variable `SCM answer' may be used.
5097 * unif.c (l2ra): Declaration prototype.
5099 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5100 defined in ramap.c).
5102 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5103 Redundant declarations removed (they are in ramap.h).
5105 * variable.h (scm_make_udvariable,
5106 scm_make_undefined_variable): Declaration corrected to
5107 correspond variable.c.
5109 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5110 Missing declarations added.
5112 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5114 * Makefile.in (distclean): Don't forget to delete fd.h.
5116 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5118 * fd.h.in, tags.h: Trivial cleanups.
5120 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5121 marksweep.h just declared functions from gc.c.
5122 * gc.h, libguile.h: Don't #include "marksweep.h".
5123 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5124 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5125 dependencies updated.
5127 * libguile.h: Don't #include "files.h"; it's been deleted.
5129 * files.c (scm_sys_delete_file): Moved to filesys.c.
5130 File is now empty; deleted.
5132 * filesys.c: scm_sys_delete_file is now here. Remove
5133 #if's; they seem to rely on remnants of an old portability
5134 regimen. If the problems come up again, solve them properly,
5135 using autoconf. Specifically: Don't test M_SYSV, and #define
5136 remove to be unlink if it's #defined; don't use remove just
5137 because HAVE_STDC_HEADERS is #defined.
5138 * filesys.h: Add declarations for scm_sys_delete_file.
5139 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5140 files.o, files.h, files.c, and files.x.
5141 * init.c: Don't #include "files.h", and don't call scm_init_files.
5143 Use SCM_P instead of PROTO; the latter intrudes on the user's
5145 * params.h: Deleted; definition of SCM_P moved to...
5146 * __scm.h: ... here, where it replaces PROTO macro.
5147 * libguile.h, smob.h: Don't #include "params.h".
5148 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5149 smob.h: Fix prototypes accordingly.
5150 * Makefile.in: Update dependencies.
5151 (inner_h_files): Remove params.h.
5153 * gc.c: #include "gc.h"; every module should include its header,
5154 to let the compiler cross-check the declarations against the
5157 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5158 simpos.h: #include "libguile/__scm.h".
5160 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5162 * init.c: Don't forget to #include smob.h and init.h.
5163 * Makefile.in: Dependencies updated.
5165 * smob.h: Use PROTO instead of #if __STDC__.
5167 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5169 * __scm.h: Doc fixes.
5171 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5172 <angles>; this allows `make depends' to work properly.
5174 * libguile.h: #include smob.h and pairs.h before the others; they
5175 define typedefs used by other headers.
5177 C files should #include only the header files they need, not
5178 libguile.h (which #includes all the header files); the pointless
5179 recompilation was wasting my time.
5180 * Makefile.in (all .o dependency lists): Regenerated.
5181 * libguile.h: Don't try to get a definition for size_t here...
5182 * __scm.h: Do it here.
5183 * _scm.h: Since this is the internal libguile header, put things
5184 here that all (or a majority) of the libguile files will want.
5185 Don't #include <libguile.h> here; that generates dependencies on
5186 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5187 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5188 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5292 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5293 anyone who uses this file will need them to define the smob
5294 printing functions. Also, get markers.h, since people will need
5295 to #define the mark functions.
5297 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5298 * ports.h: ... to here.
5300 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5301 don't rely on archaic C default type rules.
5303 * fports.h: #include "libguile/ports.h", since you need that in
5304 order to parse this.
5306 * genio.h: #include "libguile/print.h", because you need that to
5307 parse this; don't bother #including "ports.h", since print.h gets
5310 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5312 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5313 this; it's now a reference to an element of *scm_root.
5315 * debug.h: Don't #include "options.h"; the compiler won't be able
5316 to find that once the headers are installed; instead, #include
5317 "libguile/options.h".
5318 * gc.h: Same, with marksweep.h.
5319 * mbstrings.h: Same, with symbols.h.
5320 * scmhob.h: Same, with _scm.h.
5321 * smob.h: Same, with params.h.
5323 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5324 C files; there's no need for this, and it forces recompilations
5327 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5329 * error.c (scm_error): declare scm_error_callback.
5331 * error.h: prototype for scm_error_callback.
5333 * __scm.h: define lgh_error.
5334 (SCM_SYSERROR): redefine using lgh_error.
5336 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5338 * error.c (scm_error): new procedure.
5340 * error.h: prototype for scm_error.
5342 * Makefile.in (install): install scmconfig.h from the current
5343 directory, not $(srcdir).
5345 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5347 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5348 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5349 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5350 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
5351 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
5352 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5353 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5354 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5355 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5356 vports.h, weaks.h: #include "libguile/__scm.h", not
5357 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5358 dependencies are within libguile properly.
5360 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5362 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5363 when scmconfig.h doesn't exist.
5365 * load.c (scm_sys_try_load): Correct spelling.
5367 * feature.c (scm_loc_features): Make this static.
5369 * Makefile.in (libpath.h): Omit trailing slash from path. We
5370 shouldn't require it of users, so why put it here?
5372 Move code to initialize and search %load-path from ice-9 to C
5373 code, so we can use the load-path to find the ice-9 boot code;
5374 this makes it easier to run Guile without installing it. See
5375 corresponding changes in guile/Makefile.in.
5376 * feature.c: Move stuff concerned with the load path to load.c.
5377 (scm_compiled_library_path): Deleted.
5378 Don't #include libpath.h here.
5379 * feature.h: Don't mention scm_compiled_library_path.
5380 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5381 <sys/stat.h>, and <unistd.h> (if present).
5382 (R_OK): #define if the system hasn't deigned to.
5383 (scm_loc_load_path): New variable.
5384 (scm_init_load_path, scm_sys_search_load_path,
5385 scm_sys_try_load_path): New functions.
5386 (scm_init_load): Initialize scm_loc_load_path to point to the
5387 value cell of the Scheme %load-path variable.
5388 * load.h: Add declarations for scm_sys_search_load_path,
5389 scm_sys_try_load_path.
5390 * init.c: Call scm_init_load_path.
5391 * Makefile.in (feature.o, load.o): Dependencies updated.
5393 * load.c, load.h: Rewrite using PROTO macro.
5395 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5397 * gc.c (scm_cellp): New function: C predicate to determine if an
5398 SCM value can be regarded as a pointer to a cell on the heap.
5400 * gc.h: Added declaration of scm_cellp.
5402 * gdb_interface.h: New file: The GDB interface header from the GDB
5405 * gdbint.c: New file: GDB interface.
5407 * gdbint.h: New file: GDB interface.
5409 * libguile.h: Added #include <libguile/gdbint.h>.
5411 * init.c (scm_boot_guile): Added scm_init_gdbint.
5413 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5414 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5415 found if object files and source are kept separate).
5417 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5419 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5421 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5423 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5424 TK_SRC_DIR; they're not relevant any more.
5426 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5427 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5429 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5431 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5432 search path, so we can find the <libguile/MUMBLE.h> headers.
5434 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5436 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5437 implicit in the .c.o rule.
5438 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5441 Put the library path in a header file, instead of passing it on
5442 the command line in every compilation.
5443 * Makefile.in (libpath.h): New target.
5444 (feature.o): Depend on libpath.h.
5445 (clean): Delete libpath.h.
5446 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5447 * feature.c: ... #include "libpath.h" here.
5448 * .cvsignore: Ignore libpath.h.
5450 Don't install the unwashed masses of Guile header files in the
5451 main #include path; put most of them in a subdirectory called
5452 'libguile'. This avoids naming conflicts between Guile header
5453 files and system header files (of which there were a few).
5454 * Makefile.in (pkgincludedir): Deleted.
5455 (innerincludedir): New variable; this and $(includedir) are enough.
5456 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5457 (installed_h_files): Divide this up. Now this variable lists
5458 those header files which should go into $(includedir) (i.e. appear
5459 directly in the #include path), and ...
5460 (inner_h_files): ... this new variable says which files appear in
5461 a subdirectory, and are referred to as <libguile/mumble.h>.
5462 (h_files): List them both.
5463 (install): Create innerincludedir, not pkgincludedir. Put
5464 the installed_h_files and inner_h_files in their proper places.
5465 (uninstall): Corresponding changes.
5466 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5467 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5468 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5469 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5470 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5471 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5472 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5473 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5474 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5475 vports.h, weaks.h: Find __scm.h in its new location.
5476 * __scm.h: Find scmconfig.h and tags.h in their new locations
5477 (they're both "inner" files).
5479 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5481 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5483 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5485 * posix.c: Doc fixes.
5487 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5489 * socket.c: Don't include a prototype for inet_aton; just use a
5490 K&R style declaration, to avoid warnings but minimize the chance
5491 of conflicts with the system.
5493 On NextStep, <utime.h> doesn't define struct utime, unless we
5494 #define _POSIX_SOURCE before #including it.
5495 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5496 * acconfig.h: New comment text for above CPP symbol.
5497 * configure.in: Call it.
5498 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5500 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5502 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5503 testing for __EMX__.
5505 * posix.c: #include <libc.h>, if it exists.
5507 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5508 don't even know if the latter exists.
5510 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5511 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5512 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5514 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5516 (scm_init_posix): Use them when initializing the Scheme constants
5519 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5521 * Makefile.in (libdir, includedir, bindir): Use the
5522 autoconf-supplied values, instead of deriving them ourselves.
5523 (pkgincludedir, datadir, pkgdatadir): New variables.
5524 (install, uninstall): Put the header files in a special
5525 subdirectory, not in the main search path.
5527 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5528 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5530 * Makefile.in (IMPLPATH): Deleted; never used.
5532 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5533 on the Tcl/Tk source any more.
5534 (INCLUDE_CFLAGS): Remove references to the above.
5536 * Makefile.in (version.o): Corrected dependencies.
5538 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5540 * libguile.h: #include "version.h"
5542 * init.c (scm_boot_guile): Call scm_init_version.
5543 * gscm.c (gscm_run_scm): Call scm_init_version.
5545 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5546 GUILE_VERSION): AC_DEFINE these.
5547 (acconfig.h): #undef the above symbols.
5549 * Makefile.in (libobjs): Add version.o.
5550 (installed_h_files): Add version.h.
5551 (c_files): Add version.c.
5552 (gen_c_files): Add version.x.
5553 (version.o): New rule.
5554 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5555 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

5559 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5560 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,

5563 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5564 weaks.o): Add version.h to dependency lists.
5565 (markers.o): Remove duplicate rule.
5567 * version.h: New file.
5569 * version.c: New file.
5571 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5573 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5574 array; use it appropriately. Since GCC is quite happy to
5575 subscript functions, it never warned us about this; we should use
5576 -Wpointer-arith in the future. I guess we never tested
5579 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5581 * socket.c: Doc and copyright fixes.
5583 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5585 * debug.c: Fixed and improved gdb support.
5587 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5589 * socket.c: Added declaration of inet_aton to avoid compiler
5590 warning. (Hope this solution is correct.)
5592 * stime.c: Added declaration of ftime. (This is missing in
5595 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5597 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5599 * Makefile.in (c_files): add strerror.c.
5601 * strerror.c: new file from Emacs' sysdep.c.
5602 maybe configure should also check for sys_errlist.
5604 * configure.in (AC_REPLACE_FUNCS): add strerror.
5606 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5608 * debug.c (scm_init_debug): Added initialization for
5609 scm_evaluator_traps.
5611 * debug.h, debug.c: Various name changes.
5612 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5613 "debug-options-interface". See commentary in options.c.
5615 * options.h, options.c: Options now have documentation strings.
5616 Also added a long explanatory commentary.
5618 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5621 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5622 last_debug_info_frame is now updated in all cases.
5624 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5627 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5629 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5630 Added option STACK_CHECKING.
5632 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5634 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5636 * __scm.h: Removed symbols for debugging support.
5638 * acconfig.h: Added symbols for debugging support.
5640 * configure.in: Added user option for debugging support.
5641 --enable-debug will include the debugging code into libguile.a.
5643 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5644 scm_relocate_chunk_to_heap.
5646 * debug.c: New file: low-level debugging support. It also
5647 includes support for debugging with gdb. (The extensions to gdb
5648 are written by Per Bothner at Cygnus.)
5650 * debug.h: New file: low-level debugging support.
5652 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5653 argument pairs. Extensive modifications to the debugging
5654 evaluator. Added "SECTION:" commentaries to clarify what happens
5655 when, during double compilation. Renamed EVALIMP --> EVALIM.
5656 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5657 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5658 the beginning of the file. New procedure: scm_unmemocopy.
5659 Added some global state variables needed by the debugging
5660 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5661 check_entry, check_apply, check_exit, debug_options and
5662 evaluator_traps. New acro: undefine.
5664 * eval.h: Renamed EVAL --> XEVAL.
5666 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5667 --> scm_make_weak_key_hash_table.
5669 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5670 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5672 * libguile.h: Conditionally include debug.h
5674 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5675 scm_object_properties shouldn't return handle. `handle' now gets
5676 initialized in scm_set_object_properties_x. scm_object_properties
5677 doesn't any longer create an entry in scm_object_whash.
5679 * options.c: New file: handling of run time options.
5681 * options.h: New file: handling of run time options.
5683 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5685 * print.c: New procedure: scm_print_options
5687 * print.h: Defines for print options.
5689 * read.c: New procedure: scm_read_options
5691 * read.h: Defines for reader options.
5693 * root.h: Added scm_source_whash among scm_sys_protects.
5695 * srcprop.c: New file: source properties.
5697 * srcprop.h: New file: source properties.
5699 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5700 (Bug found by A. Green.)
5702 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5704 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5706 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5708 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5710 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5711 and should be called by the final client.
5713 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5715 * gc.h: Use the PROTO macro when declaring functions.
5716 * gc.c: Use the PROTO macro when declaring static functions.
5717 Remove the CPP hair around function definitions.
5719 * gc.c (scm_init_storage): Initialize scm_asyncs.
5721 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5722 preprocessor symbol; "__scm.h" is where it might get #defined.
5723 * __scm.h: Similar: #include <scmconfig.h> before testing
5726 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5728 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5730 * init.c (scm_boot_guile): Add init_func argument; call
5731 (*init_func) instead of calling scm_appinit; it's ucky to
5732 hard-code names for the user's procedures.
5733 * init.h (scm_boot_guile): Adjust declaration.
5735 * __scm.h (PROTO): New macro, for declaring functions with
5738 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5739 eliminate all the __STDC__ conditionals.
5740 (scm_boot_guile): Add declaration.
5741 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5742 Remove __STDC__ conditionals around function definitions; the
5743 declarations in init.h will provide the same information, more
5746 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5747 complain about it in the error message; the error message is
5748 adequate without that note, and there's nothing the user can do
5751 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5753 * Makefile.in (ancillary): Drop def.sed.
5755 * posix.c (scm_init_posix): Use numeric values, rather than
5756 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5757 F_OK. The symbols aren't available on some systems, and I'm
5758 pretty sure their values are fixed by common widespread practice.
5759 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5761 More functions unavailable on some systems.
5762 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5763 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5765 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5766 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5767 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5768 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5769 stub that signals an error as the #else.
5771 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.

5862 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5863 This is necessary on Ultrix, and doesn't hurt portability.

5867 Remove duplicate entries for markers.h and unif.h.

5873 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5875 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5876 every if must have an else, or else the whole command has a

5946 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5948 * gscm.h: gscm_mkarray eliminated (presumably was not being used
5949 since its definition was bogus).

5955 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5957 * ports.c: removed functions relating to the mapping between ports
5958 and descriptors. (That stuff is unix-specific and should be collected

5966 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5967 handled correctly (SCM_FREEP was applied to them) -- test for
5968 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

6162 set the multi_byte flag correctly in symbols. This is wrong.
6163 intern_obbary_soft and msymbolize should take an extra parameter.

6333 scope created by scm_with_dynamic_bindings_operation_x, swap
6334 the bindings of that scope with the corresponding globals.
6336 * continuations.c (scm_make_cont): when a continuation is captured,
6337 relocate the continuation stack chunks registered on the wind chain

6342 * eval.c (SCM_CEVAL): if the function position evaluates
6343 to a macro, process it accordingly. (Previously, macros were
6344 handled only if the function position was a symbol naming a
6345 variable bound to a macro).

6349 * eval.c (scm_m_set): allow multi-variable set! like
6352 Wed Dec 6 02:40:49 1995 Tom Lord <lord@beehive>
6354 * ports.h fports.c vports.c marksweep.c gc.c strports.c: moved the
6355 STREAM of ports into the port table and replaced it with a
6358 * repl.c (iprin1): added tc7_mb_string -- same as tc7_string.
6360 * marksweep.c (scm_gc_mark): added tc7_mb_string -- same as tc7_string.
6362 * mbstrings.c (new file): functions on multi-byte strings.
6364 * tags.h (scm_typ7_string, scm_typ7_mb_string): added a tag
6365 for multi-byte strings. Moved the string tag.
6367 * chars.h chars.c repl.c (many functions): made scm_upcase and
6368 scm_downcase functions that are safe for extended character sets.
6370 Changed the range of integer->char.
6372 Changed the type of SCM_ICHR.

6381 * guile.c (gscm_is_gscm_type): New function. (Without this how will we
6382 know that it's safe to pass an object to gscm_get_type?)
6383 (gscm_get_type): Fix tyop in error message.
6385 * variable.c (scm_variable_ref): fixed assertion test.
6386 (Robert STRANDH <strandh@labri.u-bordeaux.fr>)
6388 * gscm.h: fixed several prototypes, notably gscm_vref.
6389 Add gscm_is_eq and temporarily commented out gscm_eq (see
6390 the note in gscm.h near gscm_eq if this change effects your

6394 * pairs.c (scm_obj_length): see next entry.
6396 * gscm.h (gscm_obj_length): A way to get an integer
6397 length for lists, strings, symbols (treated as strings),
6398 and vectors. Returns -1 on error.
6400 * eq.c (scm_equal_p): fixed smob case.
6401 (William Gribble <grib@arlut.utexas.edu>)
6403 * Makefile.in (X_CFLAGS): defined.
