1 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
3 * stime.c (scm_get_internal_real_time): Do the arithmetic using
4 SCM numbers, so we won't have rollover problems; the range of a
5 signed long in milliseconds is about 25 days. (Thanks to Karl
8 Don't redefine sleep and usleep.
9 * coop.c (sleep, usleep): Remove declarations; we don't use or
10 redefine these any more.
11 (scm_thread_usleep, scm_thread_sleep): New functions which do the
12 job of usleep and sleep in a thread-friendly way. We can use
13 these in the rest of Guile. Define versions for systems both with
15 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
16 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
17 we're just using it, not redefining it, we can use a K&R style
19 (sleep): Declare this, too, if the system hasn't.
20 (scm_sleep, scm_usleep): Use scm_thread_sleep and
21 scm_uthread_sleep if they're available; otherwise, just call the
23 * scmconfig.h.in: Regenerated.
25 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
27 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
29 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
33 The argument type of usleep varies from system to system,
34 as does the return type. We really shouldn't be redefining usleep
35 at all, but I don't have time to clean that up before the 1.3.
36 release. It's on the schedule for afterwards. (Thanks to Julian
38 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
40 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
41 * scmconfig.h: Regenerated.
43 * simpos.c (scm_software_type): Procedure deleted. This isn't the
44 right way to handle system variation. Autoconf's approach is the
46 * simpos.h (scm_software_type): Declaration deleted.
48 * script.c (scm_find_executable): Don't test if unix is #defined
49 here; first, NetBSD doesn't #define it, and second, it's the wrong
50 way to go about these things. (Thanks to Perry Metzger.)
51 (dld_find_executable): Delete this MSDOS support code. This isn't
52 the way we want to support this; it needs to be rethunk at a
55 * genio.c (scm_do_read_line): Don't just politely check that the
56 line was either non-empty or EOF. Abort if it's empty and not
59 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
61 * scmconfig.h.in: Regenerated.
63 * libguile.h: Don't omit the dynamic linking functions. (Thanks
66 * genio.c (scm_do_read_line): Count lines correctly when the file
67 doesn't end in a newline.
69 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
71 * genio.c (scm_do_read_line): Maintain the line count correctly.
72 (Thanks to Harvey J. Stein and Greg Harvey.)
74 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
77 * numbers.c (big2str): Protect t from garbage collection until
78 we're done. (Thanks to Gary Houston.)
80 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
82 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
84 * Makefile.in: Regenerated.
86 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
87 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
90 Do magic to mix reads and writes on stdio FILE-based ports.
91 (Thanks to Christian Lynbech.)
92 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
94 (pre_read, pre_write): New functions.
95 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
96 local_fputs): Call them.
97 (local_fflush): Mark the port as ready for reading and writing.
98 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
99 flags on new port objects. This might not be accurate --- who
100 knows what state the FILE * is in when we get it --- but it won't
101 do extraneous calls to fflush or fseek, so it's no worse than the
102 behavior before this change.
103 * ports.h: Add comment.
105 Centralize the creation of port objects based on stdio FILE * in
106 fports.c; don't just throw them together anywhere.
107 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
108 what the rest of Guile wants. Don't set the revealed count;
109 that's only appropriate for stdin, stdout, stderr.
110 (scm_standard_stream_to_port): This function does set the revealed
112 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
113 not scm_stdio_to_port.
114 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
115 * fports.c (scm_open_file): Same.
116 * posix.c (scm_pipe): Same.
117 * socket.c (scm_sock_fd_to_port): Same.
118 * ioext.c (scm_fdopen): Same.
119 (scm_freopen): Moved from here to...
120 * fports.c (scm_freopen): ... here. This is really something that
121 munges the internals of an fport, so it should go here.
122 * fports.h (scm_stdio_to_port): Adjust prototype.
123 (scm_standard_stream_to_port, scm_freopen): New protoypes.
124 * ioext.h (scm_freopen): Prototype removed.
126 * filesys.c (set_element, get_element): This can work on both pipe
127 and file ports, so use SCM_FPORTP to typecheck, instead of testing
130 * scmconfig.h.in: Regenerated.
132 Change the definition of the functions in scm_ptobfuns so that
133 they get passed the port object, not the port's stream.
134 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
135 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
136 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
137 Pass the port itself to the scm_ptobs function.
138 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
139 scm_generic_fgets): Same.
140 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
141 getc_void_port, fgets_void_port, close_void_port): Just change the
142 argument names; these functions don't really do anything.
143 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
144 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
145 port as an argument, and use SCM_STREAM to get the stdio FILE *.
146 Also, use prototyped definitions, and get rid of the extra
148 (scm_fptob, scm_pipob): We don't need casts here any more.
149 * strports.c (prinstpt): Use prototype declarations.
150 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
151 and use SCM_STREAM to get the string info. Also, use prototyped
152 definitions, and get rid of the extra declarations.
153 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
156 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
157 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
159 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
160 scm_fgets, for consistency.
161 (scm_fptop, scm_pipob): References updated.
163 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
165 Include the source location in error messages for scripts.
166 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
167 stack is still there when we catch the error.
168 * throw.c (handler_message): If we are handling an error with a
169 message, then put together the proper arguments and call
170 scm_display_error, instead of scm_display_error_message. That
171 displays source location, if it can find it.
173 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
175 * gc.c (scm_unprotect_object): Change this so that calls to
176 scm_protect_object and scm_unprotect_object nest properly.
177 (scm_protect_object): Doc fixes.
179 * strings.c (scm_string_set_x): Require the argument to be a
180 writable string, not a substring or a symbol.
181 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
182 (Thanks to John Redford and Charbel Jacquin.)
184 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
186 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
188 * eval.c (safe_setjmp): Remove this misunderstanding.
189 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
192 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
194 * libguile.h: Mark these as C declarations, for compilation by C++
197 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
198 __cplusplus clause. I seriously doubt this ever worked the way
199 the author seems to have intended.
201 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
203 Utterly needless cleanups to hopelessly messy code.
204 * ports.c: Doc fixes.
205 (scm_fflush): Moved to ...
206 * genio.c (scm_fflush): ... here, amongst all the other port
207 method invocation functions.
208 * genio.h, ports.h: The prototype moves too.
210 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
212 * backtrace.c (display_error_body): The current frame does not
213 always have a parent frame; consider a function called directly
214 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
217 * alloca.c (alloca): Undo yesterday's changes, and simply call
218 malloc directly for storage, and abort if we don't get what we
219 want. The situation is much simpler --- just call malloc. Emacs
220 has bizarre/evil requirements (signal handlers might malloc unless
221 you set this global flag, so you have to set the flag around all
222 calls to malloc) which we are certainly not going to conform to,
223 so we can do the simple and obvious thing.
225 * coop.c (coop_condition_variable_wait): Make this function
226 static. It's only useful internally --- you should never just
227 wait on a condition variable.
228 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
230 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
232 * unif.c (scm_array_set_x): Accept any kind of number as an
233 element for a uniform vector of doubles. This is more consistent
234 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
236 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
237 works; I can't conveniently test it myself. (Thanks to Dvid
238 Tillman for the bug report.)
242 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
243 from here, not from scm_compile_shell_switches (which is a pretty
244 dumb place to do it).
245 (scm_load_startup_files): New function.
246 (scm_ice_9_already_loaded): Variable moved to here from script.c.
247 * script.c (scm_compile_shell_switches): Don't load the startup
249 (scm_ice_9_already_loaded): Variable moved.
250 * init.c (scm_load_startup_files): Prototype for new function.
251 * gh_init.c (gh_enter): Doc fix.
253 1998-10-03 <jimb@savonarola.red-bean.com>
255 Some anti-warning changes from Greg Harvey.
256 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
257 warnings when it doesn't understand our NORETURN declarations in
259 * posix.c (scm_mknod): Similar.
261 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
263 * posix.c (scm_getpwuid): If we can't find an entry, return our
264 own message, instead of using scm_syserror --- the getpwMUMBLE
265 functions don't set `errno' to anything interesting.
267 1998-10-03 <jimb@savonarola.red-bean.com>
269 Get rid of warnings from the cooperative threading system.
270 * threads.h (scm_single_thread_p, scm_yield,
271 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
272 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
273 scm_wait_condition_variable, scm_signal_condition_variable): Add
274 prototypes for these Scheme-visible functions.
275 * coop-defs.h (coop_next_runnable_thread,
276 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
277 Prototypes for these here, even though they're from iselect.c.
278 (coop_condition_variable_wait, coop_join): Add prototypes.
279 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
280 scm_threads_free_condvar): Make these smob functions static.
281 * coop-threads.h (coop_init): Give this a real prototype.
282 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
283 (coop_next_runnable_thread): No need to provide prototype; it's in
286 * scmconfig.h.in: .detarenegeR
288 * iselect.c, threads.c: Doc fixes.
290 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
292 * Makefile.in: Regenerated with a patched automake, to get
293 dependency generation right when using EGCS.
295 * inet_aton.c (inet_aton): Add prototype, to remove compiler
296 warning. (Thanks to Robert Pluim.)
298 * inet_aton.c (inet_aton): Reassure the compiler that the
299 arguments to the <ctype.h> macros are all unsigned characters, not
302 1998-10-03 <jimb@savonarola.red-bean.com>
304 Getting rid of more warnings...
305 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
306 today's change to ../configure.in.
307 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
308 * scmconfig.h.in: Regenertaded.de.,.__
309 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
310 (scm_localtime, scm_mktime): Use a const char * to manipulate the
313 * readline.c: Doc fix.
314 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
315 * readline.h (scm_filename_completion_function): Add prototype.
316 (scm_init_readline): Make this into a prototype.
318 * readline.c (scm_filename_completion_function): Use SCM_PROC to
319 declare this, instead of calling scm_make_subr manually.
321 1998-10-02 <jimb@savonarola.red-bean.com>
323 * readline.h (scm_init_readline): Add prototype for this.
324 (scm_init_readline): Make this a real prototype.
326 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
328 Warning fixes from Maciej Stachowiak:
329 * backtrace.h (scm_display_application, scm_backtrace): Add
331 * debug.c (scm_m_start_stack): Make this function static.
332 * fluids.h (scm_fluid_p): Add prototype.
333 * procprop.c (scm_i_procedure_arity): Make this function static.
334 * regex-posix.c (scm_regexp_error_msg): Make this function static.
335 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
336 * root.h (scm_dynamic_root): Add external prototype.
337 * scmsigs.h (scm_usleep): Add external prototype.
338 * script.h (scm_init_script): Use prototype, not K&R decl.
339 * stacks.h (scm_stack_id): Add external prototype.
340 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
342 1998-09-30 Mark Galassi <rosalia@cygnus.com>
344 * gh.h: took out the definitions of vset and vref, since they are
345 replaced by the proper vector routines that correspond to the R4RS
348 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
350 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
351 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
352 third argument, a C expression that should result in a SCM value,
353 which is used to initialize the variable. Reimplemented
354 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
357 * version.h (scm_libguile_config_stamp): Add prototype.
358 (From Maciej Stachowiak.)
360 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
362 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
363 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
365 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
367 * print.c (scm_iprin1): Rather than having one i, and using it in
368 several places, declare a fresh i local to each block where it is
369 used, and give it a signedness appropriate to its use in each case.
372 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
375 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
376 signed/unsigned clashes.
378 * posix.h (scm_tmpnam): Added prototype.
380 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
381 scm_make_subclass_object): Add external prototypes.
383 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
384 comparison is okay here.
386 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
388 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
389 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
391 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
394 * load.c (swap_port): Make this function static.
396 * load.c (scm_search_path): Make max_path_len and max_ext_len
397 unsigned, since they're compared against string sizes.
399 * load.c (init_build_info): Make i unsigned.
401 * ioext.h (scm_read_line): Add prototype.
403 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
404 scm_hash_fn_remove_x): Make hash bucket index local variable k
405 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
406 accurately as possible.
408 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
409 comparisons, and range checking to make sure those casts are
412 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
413 signed/unsigned comparisons.
415 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
416 avoid signed/unsigned comparisons.
417 * smob.h (scm_numsmob): Change extern declaration to match.
419 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
420 avoid signed/unsigned comparisons.
421 * ports.h (scm_numptob): Change extern declaration to match.
422 (scm_current_load_port, scm_set_port_line_x,
423 scm_set_port_column_x): New prototypes.
425 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
426 test code, and it causes warnings.
428 * gh.h (gh_int2scmb, gh_uniform_vector_length,
429 gh_uniform_vector_ref): Added prototypes.
431 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
432 debugging support unconditionally. That's backtrace.c, stack.c,
433 debug.c, and srcprop.c.
434 (EXTRA_libguile_la_SOURCES): Omit those from here.
435 * Makefile.in: Regenerated.
437 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
439 * options.c (scm_options): Bugfix: Allow empty list of options!
441 * debug.c, debug.h (scm_single_step): Removed.
442 (scm_with_traps): New procedure. This procedure could easily be
443 written in Scheme but needs to be highly optimized.
445 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
447 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
448 Check SCM_TRAPS_P before trapping.
450 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
452 Changes to avoid signed/unsigned comparison warnings.
453 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
454 (scm_gc_sweep): Make n and j local to the blocks they're used in,
455 so they can have appropriate types for each application. Make i
456 signed. Use initializers in some spots. I'll probably pay for
458 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
459 (scm_must_realloc): Make nm unsigned.
460 (init_heap_seg): Make new_seg_index and n_new_objects signed.
461 (scm_init_storage): Use prototype-style definition, and make the
463 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
464 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
466 * filesys.c (scm_readlink): Make local vars rv and size ints, to
467 avoid signed/unsigned comparison warnings, and because the return
468 value of readlink may be -1. Don't bother casting the third
469 argument to readlink.
471 * filesys.c (scm_dirname, scm_basename): Move these to their own
472 page, at the end of the file.
473 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
475 * eval.h (scm_eval_options_interface): Add external prototype for this.
476 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
478 * eval.c (scm_lookupcar1): Make this static.
480 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
481 Make these prototype declarations, not K&R-style.
483 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
484 unsigned comparison warning.
486 * appinit.c: File removed. It had a single function in it, empty,
487 whose reason for existence is explained in no documentation or
488 comment. I think it's there as a default for some Tcl-style
489 initialization, but Tcl abandoned that approach a while ago.
490 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
491 (BUILT_SOURCES): Remove appinit.x.
492 * Makefile.in: Regenerated.
494 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
496 * Makefile.in: Regenerated using the last public version of
497 automake, not the hacked Cygnus version.
499 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
501 Remove Totoro kludge.
502 * Makefile.in, scmconfig.h.in: Regenerated.
503 * init.c, readline.c: Don't check if TOTORO is #defined.
505 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
507 * Makefile.am: Adjust for new thread configuration system.
508 (INCLUDES): Include the value of THREAD_CPPFLAGS.
509 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
511 (THREAD_LIBS): Definition deleted; automake will generate such
512 things automatically.
513 * Makefile.in: Regenerated.
515 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
517 Simplify smob and port marking; set the mark bit in the generic
518 marking code, and make marker routines only responsible for
519 turning up outgoing pointers.
520 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
521 before calling the marking function. Don't call the marking
522 function if it's zero.
523 * markers.c (scm_mark0): Just return #f. This function isn't
524 necessary at all now, but it's harmless to call it. We'll leave
525 it in so other folks' code doesn't croak at link time.
526 (scm_markcdr): Don't call SCM_SETGC8MARK.
527 * async.c (mark_async): Don't call SCM_SETGC8MARK.
528 * dynl.c (mark_dynl_obj): Same.
529 * root.c (mark_root): Same.
530 * srcprop.c (marksrcprops): Same.
531 * unif.c (markra): Same.
532 * variable.c (scm_markvar): Same.
533 * ports.c (scm_markstream): Same.
534 (void_port_ptob): Specify zero for our marking function.
535 * debug.c (debugobjsmob): Same.
536 * dynwind.c (guardsmob): Same.
537 * filesys.c (dir_smob): Same.
538 * fluids.c (fluid_smob): Same.
539 * fports.c (scm_fptob, scm_pipob): Same.
540 * mallocs.c (mallocsmob): Same.
541 * regex-posix.c (regex_t_smob): Same.
542 * smob.c (freecell, flob, bigob): Same.
543 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
544 * throw.c (jbsmob, lazy_catch_funs): Same.
546 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
548 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
549 scm_copy_tree on code in order not to let memoized code to leak
550 out. Thus, scm_copy_tree needs to copy vectors as well since
551 quasiquote can introduce evaluated code also inside vector
554 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
556 * eval.c (scm_copy_tree): Removed ability to copy vectors.
558 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
559 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
562 * unif.c: Say that ivect and uvect are of type signed and unsigned
563 long instead of int in commentary so that it correctly describes
566 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
568 * stime.c: Removed declaration of strptime. (It should be
569 declared by the system headers. If it turns out that some systems
570 don't, we'll handle that then.) (Thanks to Greg Troxel.)
572 * stime.h: Renamed TIMEH --> STIMEH
574 * backtrace.c (scm_display_error, scm_display_backtrace): In order
575 to increase portability, don't use structure assignment.
576 (Thanks to Nicolas Neuss.)
578 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
580 (finalize_fd_sets): Added empty statement after last case label.
581 (Thanks to Nicolas Neuss.)
583 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
586 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
588 * init.c, readline.c: OK, I won't have these readline.x bug
589 reports anymore. We've had them since April. The current reason
590 is a completely unintelligible failure of totoro.red-bean.com to
591 do the test for rl_getc_function in libreadline correctly. This
592 kludge overrides the test if we're on totoro so that the snapshot
593 generation process can work.
595 * readline.c: Define a strdup replacement if not existent on system.
597 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
599 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
600 This change makes scm_make_vector R5RS compatible. We cannot keep
601 the third argument since people want to be able to deduce the form
602 of the C function call only by looking at R5RS. (At the same time
603 we have removed some unnecessary complexity!)
605 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
606 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
607 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
608 argument in call to scm_make_vector.
610 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
612 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
613 This macro is useful in applications.
615 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
617 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
618 (scm_parse_path, scm_search_path): New Scheme level procedures.
620 * load.h (scm_internal_parse_path, scm_parse_path,
621 scm_search_path): Declared.
623 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
625 * filesys.c (dirname, basename): New procedures.
627 * init.c (scm_boot_guile_1): Removed condition around
630 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
631 new data type (guards) for representation of C level guards and
632 data on the wind chain.
633 (scm_internal_dynamic_wind): New function.
635 * dynwind.h: Declare scm_internal_dynamic_wind.
637 * root.h (scm_root_state): Added scm_cur_loadp.
639 * root.c (mark_root): Added comment about cur_loadp.
641 * load.c: #include "dynwind.h";
642 (scm_primitive_load): Use scm_inner_dynamic_wind to update
645 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
647 * ports.c (current-load-port): New procedure.
649 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
651 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
652 not a tty, return #f.
654 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
655 to Julian Satchell and Roland Kaufmann.)
657 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
658 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
660 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
662 * debug.h, debug.c (scm_start_stack): New function. Implements
663 the guts of old scm_m_start_stack.
665 * debug.c (scm_m_start_stack): Use scm_start_stack.
667 * init.c (scm_start_stack, scm_restart_stack): Renamed to
668 start_stack and restart_stack. (These have static scope.)
670 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
672 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
673 readline functions to come in release 2.3. (Thanks to Chet
675 (handle_errors): Use the above functions.
677 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
679 * readline.c: Improvements for readline support: Handle errors
680 better; Implement before-read-hook.
682 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
684 * init.c (scm_boot_guile_1), readline.c: Test for
685 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
686 assure that we have version >= 2.1.)
688 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
690 * readline.c (scm_readline): Defer interrupts while we're calling
693 * readline.c (scm_add_history): Bugfix: Do strdup before giving
694 away the string to add_history.
695 (completion_function): Do completion for readline. (Thanks to
697 (scm_filename_completion_function): New procedure: Filename
699 (current_input_getc): New function. Use this one instead of
700 standard getc from readline.
702 * throw.c, throw.h (scm_handle_by_throw): New function: This
703 handler throws errors to next handler on the dynwind chain.
705 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
707 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
710 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
712 * procprop.c (scm_i_procedure_arity): New function. Returns arity
714 (scm_procedure_properties): Modified to return arity together with
716 (scm_procedure_property): Added the read-only property `arity'.
717 (scm_set_procedure_property_x): It is an error to set the `arity'
720 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
721 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
723 * procprop.h (scm_sym_arity): New symbol.
725 * objects.c (scm_set_object_procedure_x): New procedure: Use this
726 to set the dispatch procedure of an operator or entity object.
728 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
729 Made procedure slots read-only.
731 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
732 scm_tcs_cons_gloc case in zero args switch; Fixed args
733 construction for operators in scm_tcs_cons_gloc case in two args
736 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
738 * fluids.c: Removed use of assert.h (in order to avoid
741 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
743 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
745 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
746 change makes the evaluator safer at the cost of evaluation speed.
747 It handles the case when the user has added a non-immediate
748 improper end of the application form, e.g., `(+ 0 . x)'.
749 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
750 minimize the extra cost as much as possible. The new code is
751 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
752 problem with structs planted directly in the code (e.g. by a
753 macro). This no longer causes segmentation fault. (Thanks to
756 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
757 arg `proc' in order to be able to throw errors; New argument
760 * Removed extra #include "debug.h"
762 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
764 * scmsigs.c: Declare usleep as returning void on some systems.
765 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
768 * coop.c (usleep): Return void on some systems.
770 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
772 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
774 * coop.c: Changed return type of usleep to int.
776 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
777 isn't found in the OS.
779 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
780 isn't enabled. (Thought that I had made this change ages ago...)
782 * iselect.c: Declare bzero if not defined by OS.
784 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
786 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
787 condition. (Thanks to John Tobey.)
789 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
790 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
793 * __scm.h: Start the long-term project of moving to POSIX threads.
794 Phase 1: Classification of all critical sections.
795 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
796 for A sections. (See comments in __scm.h for details.)
798 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
799 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
801 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
803 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
804 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
805 (libpath.h, versiondat.h): Replaced dependency on Makefile with
806 dependencies on $(srcdir)/Makefile.in
807 $(top_builddir)/config.status in order to avoid circularity.
809 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
810 from argc if argc was 0 initially.
812 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
813 in generation of libpath.h.
815 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
817 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
818 libguile from 2 to 3.
820 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
822 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
824 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
826 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
827 scm_set_port_column_x, scm_port_filename,
828 scm_set_port_filename_x): Removed optional arguments. Added
829 proper argument checking.
831 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
832 stack size in machine words.
834 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
835 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
836 to Ole Myren Röhne.)
838 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
840 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
841 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
843 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
846 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
847 procedure apply: Copy argument lists before pushing them unto the
848 environment so that the environment won't get mutated due to
849 manipulation of procedure arguments. This should perhaps be
850 regarded as a temporary solution until someone finds a more
851 efficient one. (Thanks to Maciej Stachowiak.)
853 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
855 * script.c (scm_compile_shell_switches): Use "guile" as default
856 zero arg if argc is NULL.
858 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
860 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
861 is zero. (Thanks to Dirk Herrmann.)
863 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
865 * ports.c (scm_add_to_port_table): First line is now line 0
866 (was 1). (Interface changed according to suggestion by Per
869 * backtrace.c (display_header): Add 1 to line and column numbers
870 when presenting them to the user.
872 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
873 from debug.c --> eval.c
875 * eval.h, eval.c (scm_eval_options_interface): New options
877 (SCM_EVAL_STACK): New option: Size of newly created stacks,
878 i.e. stacks for new threads.
880 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
882 * eval.c (unsafe_setjmp): Removed with #if 0.
884 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
887 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
888 to avoid compiler warnings.
890 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
892 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
894 * throw.c (handler_message): Print message on current error port
895 instead of default error port. (Thanks to Maciej Stachowiak.)
897 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
899 * ports.c (scm_add_to_port_table): allocate in units of
900 struct scm_port_table *, not struct scm_port_table.
901 * posix.c (scm_close_pipe): remove the port from the port table
903 Thanks to Rob Engle for both fixes.
905 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
907 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
908 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
910 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
912 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
914 * backtrace.c (display_error_body, display_backtrace_body),
915 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
916 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
917 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
918 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
921 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
922 don't receive the jmpbuf arg anylonger.
923 (scm_catch): Don't accept a #f tag.
924 (scm_throw): Check that key is a symbol.
925 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
927 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
929 * async.c (async_pending): Removed declaration.
931 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
933 * dynwind.c (scm_wind_chain): New debug function.
935 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
936 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
937 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
938 extra layer of functions around the body and handler of a thread.
939 This extra layer makes sure that the handler is called in the
940 dynamic context of the surround (= empty dynwind list), but under
941 the *dynamic root* of the body. We can not use the dynamic root
942 of the surround since that root belongs to another thread => stack
943 is not handled correctly. It may seem ugly to use this extra
944 layer, but the extra cost in terms of execution time is really
945 negligible compared to the total amount of time required to create
946 a thread, and it would reduce maintainability to duplicate the
947 crucial and complicated steps performed by cwdr.
949 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
950 (SCM_ALLOW_INTS): Added thread switching code before interrupts
951 get re-enabled. The important effect of this is that interrupts
952 are blocked during thread switching so that thread data structures
953 don't risk getting messed up by an unfortunate signal.
954 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
955 seems to do more aggressive optimization which actually move
956 instructions around in these macros in a fatal way. Therefore:
957 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
958 just superstitious...)
959 (SCM_TICK): Maybe do a context switch and take care of asyncs.
960 This macro should be used instead of SCM_ASYNC_TICK since the
961 latter doesn't do context switches any more.
963 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
964 instead of SCM_ASYNC_TICK.
966 * coop.c, iselect.c: Since thread switches are now performed with
967 interrupts masked, we can't use the old mechanism of delivering
968 signals immediately when they arrive. Signals must instead be
969 delivered when the asyncs run *after* the end of the critical
970 section in scm_internal_select. But this also means after context
971 switch so that the signal will be delivered to a different thread.
972 To avoid this, I have changed the protocol of
973 coop_wait_for_runnable_thread and friends so that they are allowed
974 to return the original thread. So, if a signal arrives during
975 scm_internal_select, we won't any longer be forced do a context
976 switch, but can remain in the same thread and deliver the signal
979 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
980 scm_asyncs_pending and made it global.
982 * iselect.c: Small fixes.
984 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
985 coop_condition_variable_init, coop_condition_variable_wait,
986 coop_condition_variable_signal): Changed return type from `void'
987 to `int'. This is to adhere closer to the pthreads interface.
988 This, in turn, is part of an attempt to provide C versions of the
989 mutex and condition variable primitives which can be part of a
990 frontend to COOP or pthreads.
992 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
993 coop_condition_variable_destroy): New functions.
995 * coop-threads.c (scm_wait_condition_variable): Use
996 coop_condition_variable_wait_mutex.
998 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
999 Definitions moved to coop-defs.h.
1001 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1002 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1003 scm_cond_destroy): New C interface to mutecis and cond vars.
1005 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1007 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1009 * iselect.c: Now several threads can wait on the same file
1010 descriptor. The behaviour is compatible with OS select: All
1011 threads waiting for the fd return with the same status.
1013 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1015 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1016 Can spawn a thread from application C code.
1018 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1020 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1021 gh_doubles2scm): New functions.
1023 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1025 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1026 commented-out version of gh_eval_str()
1028 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1030 * socket.c (scm_bind): free soka after use.
1032 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1034 * stime.c (tzvar): new variable.
1035 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1036 avoid memory leaks when allocating.
1038 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1040 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1043 * gc.c, tags.h: Doc fixes.
1045 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1047 * eval.c (macro-eval!): Removed. This function was a design bug.
1048 It allowed memoized code to leak out to the scheme level. Most
1049 things that you could do with `macro-eval!' can be done with
1052 1997-12-20 Tim Pierce <twp@skepsis.com>
1054 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1055 scm_fgets now depends on ftell(3) to know how many bytes were
1058 1997-12-15 Tim Pierce <twp@skepsis.com>
1060 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1061 dealing with strings.
1063 1997-12-13 Tim Pierce <twp@skepsis.com>
1065 Make %read-line more suitable for implementing read-line efficiently.
1066 * ioext.c (scm_read_line): Strip the terminating newline from a
1067 string, and return a cons of the string and its terminator.
1069 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1070 of the string that is read is stored in this memory location.
1071 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1072 * genio.c, genio.h (scm_do_read_line): Update caller.
1073 * ports.h (scm_ptobfuns): Update typedef.
1074 * fports.c (scm_fptob, scm_pipob): Update struct.
1076 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1078 * filesys.c (set_element): Return file descriptor.
1079 (fill_select_type): Return the highest file descriptor.
1080 (scm_select): Tell select about the highest file descriptor. On
1081 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1082 Therefore the extra overhead for calculating the maximum fd seems
1083 to be more than compensated. Is this correct? In any case,
1084 scm_internal_select will be much faster with this info.
1085 (scm_select, fill_select_type, set_element): Don't accept any kind
1086 of object in the file descriptor list or vector.
1088 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1090 * iselect.c (finalize_fd_sets): Bugfix.
1092 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1094 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1095 when using scm_internal_select (since we might switch to another
1098 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1100 * simpos.c (scm_system): always define: use sysmissing if not
1101 available. Check for HAVE_SYSTEM instead of _Windows (does
1102 Windows lack system or does it have an unusable one?).
1103 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1104 Let the argument be optional: if not supplied, call system(NULL).
1106 * ports.c (scm_close_port): relax the type check from OPPORTP to
1107 PORTP; closing a closed port is allowed.
1109 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1111 * fports.c (scm_fgets): Return if the last char in a chunk is
1112 newline. When fgets returns a string whose length is `size-1', it
1113 is ambiguous whether a whole line was retrieved, so we must check
1114 explicitly whether a line terminator is present.
1116 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1118 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1119 before taking the CDR. (Thanks to Harald Meland.)
1121 * filesys.c (scm_stat): Slightly optimized.
1123 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1125 * ports.c (scm_close_port): Make sure the port is open before
1128 * guile-snarf.in: Pass args through to gcc in a way that preserves
1129 whitespace boundaries. (Thanks to Greg Badros.)
1131 1997-12-02 Tim Pierce <twp@skepsis.com>
1133 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1134 statement. (Thanks to Doug Evans for pointing this out.)
1136 1997-12-01 Tim Pierce <twp@skepsis.com>
1138 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1140 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1142 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1143 errno macro expansion of this field name. (errno is a C
1144 preprocessor macro on some systems.)
1146 1997-11-29 Tim Pierce <twp@skepsis.com>
1148 * iselect.c: Doc fix.
1150 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1152 * init.c (scm_start_stack): Removed initialization of
1153 scm_the_last_stack_var.
1155 * backtrace.h: Declare scm_the_last_stack_var.
1157 * backtrace.c: Define scm_the_last_stack_var.
1159 * root.c (mark_root): Don't mark the_last_stack_var.
1161 * root.h (scm_root_state): Removed the_last_stack_var.
1163 * throw.c: Added #include "fluids.h"
1164 (ss_handler): `the-last-stack' is now a fluid.
1166 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1167 --> the_last_stack_fluid.
1169 * backtrace.c: Added #include "fluids.h"
1170 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1171 (scm_backtrace): `the-last-stack' is now a fluid.
1173 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1174 after scm_init_fluids.
1176 1997-11-28 Tim Pierce <twp@skepsis.com>
1178 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1180 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1181 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1183 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1185 * iselect.c (coop_next_runnable_thread,
1186 coop_wait_for_runnable_thread): Disable interrupts so that no
1187 async is executed before a potential error_revive.
1188 (scm_internal_select): Disable interrupts during the parts of the
1189 code which manipulate the sleep queue and the file descriptors.
1191 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1193 * Makefile.am: Added iselect.c and iselect.h.
1195 * coop.c (coop_qinit): Initialize fields used by
1196 scm_internal_select.
1197 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1198 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1199 replacement in iselect.c.
1200 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1201 coop_join): If GUILE_ISELECT enabled, use
1202 coop_wait_for_runnable_thread instead of
1203 coop_next_runnable_thread.
1204 (usleep, sleep): New replacements for system functions if
1205 GUILE_ISELECT is enabled.
1207 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1209 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1211 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1212 iselect.h. Implement Scheme level `select' using
1213 scm_internal_select. (See NEWS.)
1215 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1217 * init.c: Call scm_init_iselect.
1219 * iselect.h, iselect.c: New files. Implements
1220 scm_internal_select. (See NEWS.)
1222 1997-11-27 Tim Pierce <twp@skepsis.com>
1224 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1225 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1226 and scm_must_free, since ultimately the string returned will be copied
1227 by scm_makfrom0str anyway. Also, read any characters that may have
1228 been pushed onto the port with scm_ungetc.
1229 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1230 * ioext.c (scm_read_line): Free string after Guilifying it.
1231 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
1233 1997-11-26 Anthony Green <green@hoser.cygnus.com>
1235 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1237 * gh.h: Safely wrap prototypes for c++ usage.
1239 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1241 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1242 gh_repl (argc, argv).
1244 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1246 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1247 and to invoke scm_shell().
1248 (gh_launch_pad): took out the loading of boot-9.scm from here,
1249 since it is probably best to let the user control that. In fact,
1250 gh_repl() now invokes scm_shell() which does that.
1252 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1254 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
1257 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
1259 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
1260 yesterday's underscore patch. (Thanks to Marius Vollmer for
1263 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
1265 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
1266 DLSYM_ADDS_USCORE is not defined.
1268 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
1270 * gh_data.c (gh_uniform_vector_length):
1271 (gh_uniform_vector_ref): started implementing the uniform types in
1274 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1276 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1277 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1279 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1281 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1282 configure.in was changed).
1284 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1286 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1287 * Makefile.in: Regenerated.
1289 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1291 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1292 OPORT is an `open' port, not an output port.
1294 * filesys.c (scm_close, set_element, get_element, scm_chown,
1295 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
1296 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
1297 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
1298 scm_close_port, scm_port_line, scm_set_port_line_x,
1299 scm_port_column, scm_set_port_column_x, scm_port_filename,
1300 scm_set_port_filename_x, scm_port_mode,
1301 scm_close_all_ports_except, scm_set_current_output_port,
1302 scm_set_current_error_port): Likewise
1303 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1304 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1306 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1307 * backtrace.c (display_backtrace_body): Likewise
1308 * fports (scm_setvbuf): Likewise
1309 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
1310 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
1311 scm_getpeername, scm_send, scm_sendto): Likewise
1312 * unif.c (scm_uniform_array_write): Likewise
1314 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1316 Minor problems with substring-related tag changes.
1317 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1318 exactly what we want to leave in to detect substrings.
1319 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1320 * tags.h: Fix diagrams and comments describing the S tag bit;
1321 remove vestigial remarks about the D tag bit.
1322 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1323 * strings.c: Formatting tweaks.
1325 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1326 variable first; then SCHEME_LOAD_PATH, with a warning message.
1327 (scm_parse_path): New function.
1328 * script.c: Doc fixes.
1330 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1332 Readline support, from Daniel Risacher.
1333 * readline.c, readline.h: New files.
1334 * init.c: #include "readline.h".
1335 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1336 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1337 * Makefile.in: Regenerated.
1338 * scmconfig.h.in: Regenerated, after change to ../configure.
1340 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1342 * gh.h: gh_vector_set -> gh_vector_set_x
1344 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1346 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1347 with the ! -> _x mapping when going from Scheme to C.
1349 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1351 * gh.h (gh_reverse):
1359 (gh_assoc): added these gh_ functions implemented as macros.
1361 * gh_predicates.c (gh_null_p):
1362 (gh_string_equal_p): added these two missing predicates.
1364 * gh_list.c (gh_append):
1369 (gh_set_cdr_x): added these routines as I go through and try to
1370 complete the picture R4RS functions that should be mirrored in the
1373 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1375 * tags.h (scm_tc7_substring): Changed the comment and code to
1376 conform with the changes below. Folks! We have suddenly two new
1377 free tc7 codes!!! Jummy, jummy!
1379 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1381 * Makefile.in: Rebuilt.
1382 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
1384 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
1385 * unif.c (scm_vector_set_length_x): Don't handle multibyte

1397 (scm_gc_sweep): Likewise.
1398 * eval.c (SCM_CEVAL): Don't handle mbstrings.
1399 * eq.c (scm_equal_p): Use SCM_TYP7S, not SCM_TYP7SD.
1400 * tags.h (SCM_TYP7SD): Removed.
1401 (SCM_TYP7D): Removed.
1402 (scm_tc7_mb_string): Removed.
1403 (scm_tc7_mb_substring): Removed.
1404 * print.c (scm_iprin1): Handle char printing directly. Don't
1406 Don't include "mbstrings.h".
1407 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1408 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1410 Don't include "mbstrings.h".
1411 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1412 (SCM_SYMBOL_SLOTS): Define as 4.
1413 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
1414 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
1415 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
1416 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,

1434 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
1435 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
1437 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1439 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1441 * gh_test_c.c (c_vector_test): some improvements on the vector
1444 * gh.h (gh_vector): this used to exist but do the wrong thing.
1445 Now it (almost) does the right thing, though it takes a list
1446 instead of the individual arguments. I need to see how it could
1448 (gh_list_to_vector): added this function as a macro. Corresponds
1449 to Scheme's (list->vector ...).
1450 (gh_vector_to_list): added this function as a macro. Corresponds
1451 to Scheme's (vector->list ...).
1453 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1454 gh_vector_ref, so that it resembles the Scheme routines more.
1455 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1456 resembles the Scheme routines more.
1457 (gh_make_vector): this used to be (stupidly) called gh_vector().
1458 This is the right name, since it does the same thing as the Scheme
1459 (make-vector ...) procedure.
1461 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1463 * ports.h: #include "libguile/print.h"
1465 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
1466 Some indentation fixes.
1468 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1469 longer a user field; New field: class_flags.
1471 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1473 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1475 * gh_data.c (gh_bool2scm): new function which replaces
1476 gh_int2scmb(), which is now tagged as obsolete.
1478 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1480 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1481 macros should by convention not test for NIMPness.)
1482 (SCM_COERCE_OPORT): Adjust indentation.
1484 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1485 SCM_NIMP test before SCM_PRINT_STATE_P.
1487 * struct.c, struct.h, gc.c: Renamed:
1488 scm_struct_i_layout --> scm_vtable_index_layout
1489 scm_struct_i_vcell --> scm_vtable_index_vcell
1490 scm_struct_i_vtable --> scm_vtable_index_vtable
1491 scm_struct_i_printer --> scm_vtable_index_printer
1492 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1494 * struct.c (scm_print_struct): Use new printer slot; Default
1495 printing: Also output hex code of vtable so that type identity
1496 will be indicated as well.
1497 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1498 Removed struct_printer_var; Removed struct-vtable-offset;
1499 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1500 vtable-offset-user): New constants.
1502 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1503 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1504 If this slot contains a procedure, use that to print structures of
1505 the type represented by this vtable.
1507 * print.c (scm_iprin1): Don't print arguments of macro
1508 transformers. (They are always: exp env.); Bugfix: Unmemoize
1509 transformer source with correct environment.
1511 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1513 Streamlining of call-with-dynamic-root:
1515 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1516 there is now only one catch.
1517 (cwdr_outer_body): Removed.
1518 (cwdr_handler): New function.
1519 (scm_internal_cwdr): New function to perform the function of cwdr
1520 but take args that are more useful to C code. Also, the handler
1521 is now invoked *outside* of the new dynamic root, like the docs
1522 say. We no longer have to catch absolutely all errors, the caller
1523 is responsible for using a handler that does not throw, if he
1525 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1526 * root.h (scm_internal_cwdr): New prototype.
1528 Even more but risky streamlining:
1530 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1531 allocation of the jumpbuf of a root continuation. The changes
1532 below are controlled by it. They are now deactivated.
1533 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1534 the JMPBUF of the scm_rootcont to NULL before returning.
1536 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1537 when they are non-NULL.
1538 (scm_gc_mark): Likewise, mark only when non-NULL.
1540 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1541 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1543 * gc.c (scm_done_malloc): New function.
1544 gc.h (scm_done_malloc): New prototype.
1546 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1547 (struct scm_print_state) [revealed]: New field.
1548 (scm_print_state_vtable): Make visible to the outside world for
1549 type checking purposes.
1550 (scm_valid_oport_value_p): New prototype.
1552 * print.c (scm_valid_oport_value_p): New function to check whether
1553 a certain value is acceptable as a port argument.
1554 (scm_print_state_vtable): New variable.
1555 (scm_free_print_state): Set `revealed' field to false.
1556 (scm_iprin1): Call user supplied closure printer with
1557 scm_printer_apply. Print in the traditional way when there isn't
1558 one or when it returns #f.
1559 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1560 Accept a port/print-state pair in addition to just a port.
1561 (scm_prin1): Don't return the print_state to the pool when it has
1563 (scm_printer_apply): Set `revealed' field of print_state to true.
1564 (scm_init_print): Set scm_print_state_vtable.
1565 (print_state_fluid, print_state_fluid_num): Removed.
1567 * throw.h (scm_handle_by_proc_catching_all): New prototype
1568 throw.c (scm_handle_by_proc_catching_all): New function
1570 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1572 * Makefile.in: Regenerated with automake 1.2c.
1574 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1576 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1577 was looping endlessly.
1579 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1581 * strports.c (scm_eval_string): Don't close the port.
1583 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1584 former returns a nice normal integer. (Thanks to Daniel
1587 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1589 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1590 makefile variable as a build parameter called LIBS. The
1591 build-guile program will use this, for the time being.
1592 * Makefile.in: Regenerated.
1594 Thanks to Shiro Kawai:
1595 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1596 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1599 * Makefile.in: Regenerated with automake 1.2a.
1601 * script.c (scm_compile_shell_switches): If we hit the -c or --
1602 arguments, don't set the car of (command-line) to scm_usage_name,
1603 the prettified name of the guile executable; give it the full
1604 path, the way shells usually handle $0.
1606 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1608 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1609 Scheme-level name `array-map' and renamed `serial-array-map' to
1610 `serial-array-map!'.
1612 * backtrace.c: Introduced exception handlers which now enclose
1613 `display-error' and `display-backtrace' so that error reporting
1614 won't get into infinite loops if an error occurs during displaying
1615 of the error. This can very easily happen with user supplied
1616 print call-back routines.
1618 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1620 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1621 the names `serial-array-map' and `array-map' should be removed.)
1623 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1625 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1626 Added #include "objects.h"
1628 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1629 Add #include "feature.h".
1631 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1632 (modinclude_HEADERS): Added objects.h.
1634 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1635 This test is needed at many places in the code and should be
1636 abstracted. (Motivated by the need of this test in libguiletk.)
1638 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1639 (scm_eval_string), load.c (scm_primitive_load,
1640 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1641 Use SCM_EOF_OBJECT_P.
1643 * eval.c (scm_init_eval): Add feature `delay'.
1645 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1647 * scmhob.h: Removed.
1649 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1651 * list.h (SCM_LISTn): New macros. Make list creation in C code
1652 prettier. The idea comes from STk.
1654 * sequences.h, sequences.c, append.h, append.c: Removed. These
1655 files implemented non-R4RS operations which would encourage
1656 non-portable programming style and less easy-to-read code.
1658 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1661 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1662 sequences.h, #include append.h.
1664 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1667 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1669 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1671 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1673 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1675 * eval.c: Added #include "objects.h"
1677 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1680 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1681 adjacent smob numbers.
1683 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1685 * procprop.h: Added declaration of scm_i_inner_name.
1687 * gsubr.c: New global symbol scm_i_inner_name.
1689 * debug.c (scm_procedure_name): Try procedure property
1690 `inner-name' if `name' fails.
1692 * print.c (scm_iprin1): Use scm_macro_name.
1694 * eval.c (scm_m_define): Give names to macros as well; Only the
1695 first top-level definition gives a procedure/macro a name.
1696 Otherwise confusing names can turn up in backtraces.
1697 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1698 `name'; Give names to macros as well.
1700 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1701 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1704 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1706 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1708 (prinmacro): Removed. The code has been moved/merged into print.c
1709 in order to decrease code redundancy. We want macros to print in
1710 a way equivalent to procedures, and it would be silly to duplicate
1711 the required code. (We don't want to maintain two places.)
1712 (macrosmob): Print field is now a NULL pointer.
1714 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1715 scm_macro_transformer): New prototypes.
1716 (scm_tc16_macro): Declared.
1718 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1719 are now printed in a way equivalent to procedures.
1721 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1723 * procs.h (scm_closure_p): Added declaration.
1725 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1727 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1728 Shouldn't pass "heap" as the subr name.
1730 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1732 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1733 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1734 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1735 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1736 SCM_BOOL_T. Any non-false value is true.
1738 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1740 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1741 scm_gensym): Added prototypes.
1743 * symbols.c (scm_gensym): New function. This will speed up
1744 certain types of applications (such as macro systems) which
1745 generate lots of symbols.
1747 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1749 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1751 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1753 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1754 specifier, since (2) or (2 . 3) would cause SEGV.
1755 (scm_transpose_array): more argument checking fixes.
1757 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1759 * Makefile.in: Regenerated.
1761 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1763 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1765 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1767 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1769 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1771 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1772 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1775 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1776 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1777 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1778 scm_array_p, scm_array_rank, scm_array_dimensions,
1779 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1780 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1781 scm_array_prototype): Added case scm_tc7_wvect.
1783 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1785 * errno.h: prototype for scm_strerror.
1786 * error.c (scm_strerror): new procedure.
1788 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1790 * list.c (scm_list_append_x): Allow non-pair as last argument.
1791 This is consistent with the R4RS append and is probably the
1792 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1794 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1796 * stime.h: prototype for scm_times.
1797 * stime.c (scm_times): new procedure.
1798 * ioext.c (scm_fseek): if the first argument is a file descriptor
1800 (scm_ftell): if the first argument is a file descriptor call lseek
1802 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1803 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1805 (scm_chown): if the first argument is a port or file descriptor,
1807 (scm_truncate_file): new procedure.
1808 Add DEFER/ALLOW INTS to a few other procedures.
1809 (scm_fsync): new procedure.
1810 (scm_open_fdes): new procedure.
1811 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1813 (scm_fcntl): the first argument can now be a file descriptor. The
1814 third argument is now optional.
1816 * posix.c (scm_execl, scm_execlp): make the filename argument
1817 compulsory, since omitting it causes SEGV.
1818 (scm_sync): return unspecified instead of #f.
1819 (scm_execle): new procedure.
1820 (environ_list_to_c): new procedure.
1821 (scm_environ): use environ_list_to_c. disable interrupts.
1822 (scm_convert_exec_args): take pos and subr arguments and
1823 improve error checking.
1825 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1827 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1828 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1829 argument to SCM_ASSERT. Furthermore, the name of the function
1830 should be passed as first argument when signalling
1831 SCM_WNA. (Thanks to Thomas Morgan)
1833 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1834 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1835 dispatches on the number of actual args has a default case
1836 reporting an internal error. This is a vestige from a version
1837 that mallocated a SCM vector to hold the arguments. In the
1838 current version this check is too late: if it ever happens we will
1839 have already overstepped the bounds of the array.
1841 Also, the patch [...] adds a check for too many actual arguments."
1843 mdj: Removed check for "internal programming error".
1845 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1847 * gh_io.c (gh_write): New function.
1849 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1850 throw.c (scm_internal_stack_catch): New sibling to the other catch
1851 functions. Code moved from gh_eval.c.
1852 throw.h: Added header.
1853 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1854 scm_internal_stack_catch.
1856 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1858 * ioext.h: fix up prototypes.
1859 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1860 Scheme name is now dup->fdes.
1861 (scm_dup_to_fdes): make the second argument optional and
1862 fold in the functionality of scm_primitive_dup.
1863 (scm_primitive_dup): deleted.
1865 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1867 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1868 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1869 ultrix are defined. Use setvbuf instead of setbuf.
1870 (scm_setvbuf): new procedure.
1871 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1872 (scm_setfileno): moved from ioext.c.
1873 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
1874 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
1876 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1878 * fluids.c (scm_fluid_p): New function.
1879 * fluids.h (scm_fluid_p): New prototype.

1883 * print.c (scm_iprin1): Enter printed structures into the print
1884 state as nested data while they are printed.
1885 (print_state_fluid, print_state_fluid_num): New variables.
1886 (scm_init_print): Initialize them.
1887 (scm_iprin): If print_state_fluid carries a print_state, use that
1888 instead of creating a new one.
1889 (scm_printer_apply, apply_stub, struct apply_data): New
1890 definitions to help with calling printer functions written in
1892 * print.h (scm_printer_apply): New prototype.

1905 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1906 SCM_ASSERT: arg comes before pos.
1908 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1910 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1911 to a list of length zero correctly.
1913 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1915 Supply an `fgets' method for port objects to do fast line i/o.

1929 * ioext.h: removed scm_duplicate_port prototype.
1931 * ioext.c (scm_primitive_dup2): return the new file descriptor
1932 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1934 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1935 stream has been set.
1936 (scm_duplicate_port): deleted, there's now an implementation in
1938 (scm_primitive_dup2): do nothing if newfd == oldfd.
1940 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
1942 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
1945 * ioext.h: new prototypes.
1946 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
1948 * fluids.c (next_fluid_num): don't do
1949 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
1951 * ports.h: prototypes too.
1952 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
1954 * fports.h: prototype too.
1955 * fports.c (scm_evict_ports): moved from ioext.c.
1957 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>

1964 and ports (scsh compatible).
1966 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
1969 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
1971 * fluids.c, fluid.h: New files.
1972 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
1973 (modinclude_HEADERS): Added "fluids.h"
1975 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to

1981 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
1982 (scm_make_root): Call scm_copy_fluids to make fluid bindings
1983 unique for the new root when it has a parent.
1985 * smob.h: Include "libguile/print.h" to make scm_print_state
1988 * dynl.c (free_dynl_obj): New function to free the dynamic object
1989 data. (dynl_smob): Use it.
1990 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1991 the dynamic object data below the linking of the object to avoid
1992 memory leak when the linking code throws an error. Now the code
1993 leaks a whole dynamically linked library when must_malloc throws,
1994 but that should be much less likely.
1996 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1998 Changes to compile under gnu-win32, from Marcus Daniels:
1999 * stime.c (tzset): If tzset isn't provided, make it a NOP.
2000 (scm_localtime): Change SCM_EOF to SCM_EOL.
2001 (scm_mktime): Likewise.
2002 * socket.c: Don't include sys/un.h unless autoconf tells
2003 us Unix domain sockets are available.
2004 (scm_fill_sockaddr): Ignore Unix domain code.
2005 (scm_addr_vector): Likewise.
2006 (scm_init_addr_buffer): Likewise.
2007 (scm_socketpair): Don't include unless socketpair was
2008 found during autoconf.
2009 * simpos.c (SYSTNAME): Treat cygwin like Unix.
2010 * scmsigs.c (scm_pause): Don't include unless pause was found
2012 * posix.c (scm_getgroups): Don't include unless support function
2013 was found during autoconf (in this case, getgroups).
2014 (scm_setpwent): For setpwent.
2015 (scm_setegid): For setegid.
2016 * net_db.c (scm_inet_netof): Don't include unless support
2017 function was found during autoconf (in this case, inet_netof).
2018 (scm_lnaof): For inet_lnaof.
2019 (scm_inet_makeaddr): For inet_makeaddr.

2031 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
2032 scm_misc_error, not SCM_EOF.
2034 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
2035 arguments for formatting the error message, not SCM_BOOL_F. I
2036 think this is left over from the (eq? '() #f) days.
2038 * read.c (recsexpr): Give this a dummy definition if
2039 DEBUG_EXTENSIONS isn't #defined.
2041 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

2046 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
2048 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
2051 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
2053 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
2054 alloca.lo will be included in @LIBLOBJS@. Something better than
2055 this should be possible.
2056 * Makefile.in: Regenerated.
2058 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2060 * simpos.h: prototype for scm_primitive_exit.
2061 * simpos.c (scm_primitive_exit): new procedure, terminates the
2062 process without unwinding the stack.
2064 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
2066 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2067 argument and logior its components together, so the user doesn't
2068 have to do this explicitly. Also, if regexp/basic is supplied, then
2069 turn off REG_EXTENDED.
2070 (scm_init_regex_posix): New regexp/basic symbol.
2071 (REG_BASIC): #define this if it is not already present.
2073 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2075 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
2076 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
2077 (CLEANFILES): New target, clean versiondat.h, libpath.h.
2078 (DISTCLEANFILES): New target, clean *.x.
2079 * Makefile.in: Regenerated.
2081 Tue Jun 24 00:29:07 1997 Jim Blandy <jimb@floss.red-bean.com>
2083 * script.c (scm_compile_shell_switches): Add 1997 to copyright
2084 years in usage message.

2087 * Makefile.in: Regenerated.
2089 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2090 flag; I don't think we support it.
2091 (scm_make_regexp): Make sure the user doesn't pass the
2094 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2096 (scm_init_regex_posix): Define constants for the REG_mumble flags;
2097 name them according to the SCSH convention: regexp/mumble.
2099 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
2101 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
2103 * Makefile.am (libpath.h): Include the values of all the standard
2104 Makefile directory variables. Print a message, but don't print
2106 (versiondat.h): Print a message, but don't print all the commands.
2107 * load.c: #include "alist.h".
2108 (init_build_info): New function.
2109 (scm_init_load): Call it.
2110 * Makefile.in: Regenerated.
2112 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2114 * root.c: Establish a reliable catch-all handler for the new root.
2115 After all the Scheme handler function might signal an error too,
2116 and we don't want to lose that.
2117 (cwdr_inner_body): Renamed from cwdr_body.
2118 (cwdr_outer_body): New function, to establish the user's handler,
2119 and pass control to cwdr_inner_body.
2120 (cwdr): Establish the reliable catch-all handler here, and pass
2121 control to cwdr_outer_body.
2122 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2123 the user's handler through to cwdr_outer_body.
2124 * throw.c (scm_handle_by_message): Move guts into....
2125 (handler_message): New static function.
2126 (scm_handle_by_message_noexit): New function.
2127 * throw.h (scm_handle_by_message_noexit): New prototype.
2129 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2130 across this. Only works on GCC. Otherwise, we hope for the best.
2131 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2132 the feeling that real thread systems will not need this...
2134 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2136 Try to detect when people are using one version of libguile and a
2137 different version of ice-9. People have been skewing things and
2138 sending in bug reports.
2139 * Makefile.am (versiondat.h): New file to generate.
2140 * version.c: #include "versiondat.h", to get version info.
2141 (scm_libguile_config_stamp): New function.
2142 * script.c: #include "version.h".
2143 (scm_compile_switches): Call scm_version to get version number.
2144 * scmconfig.h.in, Makefile.in: Regenerated.
2145 * Makefile.in: Regenerated.
2147 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2148 primitive definitions under their Scheme names.
2150 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2151 1:2. Helps avoid confusion between installed and uninstalled libs.
2153 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2156 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2157 backslash from definition; this should be used like: GDB_INTERFACE;
2159 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2161 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2162 new port unbuffered until its stream has been set.
2164 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2166 * ports.h: new prototype.
2167 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2169 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2171 Make things compile neatly under Sun's C compiler.
2172 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2173 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2174 unsigned, because that's what the ANSI function takes.
2175 * extchrs.h (xmbtowc): Corresponding change to prototype.
2176 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2178 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2179 argument plain char *.
2180 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2182 * tag.c (scm_tag): Remove unreachable statement.
2183 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2184 top of the word, it should be unsigned.
2186 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2187 is defined, to avoid warnings; it's only used in the
2188 conflict-checking code. Which might go away anyway.
2189 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2190 conditionals; put the label definition in an #if too, to stifle
2193 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2194 ChangeLog-threads in the distribution.
2195 * Makefile.in: Regenerated.
2197 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2199 * guile-snarf.in: Changed regexp to support CPPs that insert
2200 whitespace between lexical tokens (which munges the `%%%' snarf
2203 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2205 * load.c (scm_init_load_path): Append $(datadir)/guile to
2206 %load-path, so modules do not have to be installed in Guile's
2207 current version directory.
2209 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2211 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2212 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2213 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2214 call the sysdep functions with deferred ints.
2215 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2216 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2217 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2220 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2223 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2225 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2227 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2229 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2232 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2234 * eval.c (scm_lookupcar1): New procedure to cope with a race
2235 condition during lookup (when using threads).
2236 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2237 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2240 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2242 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2243 supplied. (Change from Tim Pierce.)
2245 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2247 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2248 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2249 default and not `()'. `#f' is the canonical non-value in Scheme,
2252 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2254 * struct.c (struct_printer): New variable that holds a handle on
2255 the Scheme variable *struct-printer*. This variable can be set by
2256 Scheme code to override the printing of structures.
2257 (scm_print_struct): If struct_printer is set, call it. If it is
2258 not set, or returns #f, print the structure in the old fashion.
2259 Include "eval.h" for scm_apply.
2261 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2263 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2264 scm_struct_i_n_words to get the number of fields, not
2265 -scm_struct_n_extra_words.
2267 On the route to fancier struct printing:
2268 * struct.c (scm_print_struct): New function to print a structure.
2269 Include "genio.h" to support it. This function doesn't do
2270 anything interesting right now, but I think it should be here
2272 * struct.h: Include "print.h" and add prototype for
2274 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2275 print structures ourself.
2277 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2279 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2280 before applying the handler in case it doesn't return.
2282 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2284 * scmsigs.h, async.h: updated.
2286 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2289 * posix.c (scm_uname): interpret only negative values as an error.
2290 Solaris normally returns a positive value.
2292 * script.c (scm_compile_shell_switches): if we are not going into
2293 an interactive repl, set scm_mask_ints to zero so that asyncs can
2296 * simpos.c (scm_system): don't ignore/unignore signals around
2299 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2302 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2303 done in boot-9.scm instead.
2305 * scmsigs.c, async.c: Major rewriting of signal handling code.
2306 (scm_sigaction): new procedure.
2307 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2309 (scm_raise): return unspecified, throw error on failure.
2311 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2313 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2314 feature, to help boot-9.scm decide whether to import the regex
2317 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2319 * eval.c: Include scmconfig.h at the beginning of the file so that
2320 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2323 * regex-posix.c: #include "_scm.h" before conditionally #including
2324 <regex.h>; the former defines HAVE_REGCOMP.
2326 * regex-posix.c: #include <regex.h> conditionally, so the file is
2327 CPP'able (for dependency scanning) even on systems that don't have
2330 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2332 Add new R4RS-compliant syntax for keywords.
2333 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2334 regardless of the setting of the `keywords' read option.
2335 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2336 can be re-read no matter what the setting of the `keywords' read
2339 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2341 Add support for POSIX regular expressions.
2343 * regex-posix.c, regex-posix.h: New files. (Some code
2344 is taken liberally from rx/rgx.c in the old Guile dist.)
2346 * init.c: Include regex-posix.h.
2347 (scm_boot_guile_1): Call scm_init_regex_posix.
2349 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2350 Add regex-posix.[ch] sources.
2351 * Makefile.in: Regenerated.
2353 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2354 to do this automatically? It didn't for me, bleh.)
2356 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2358 * fports.c (print_pipe_port): New function.
2359 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2360 latter doesn't even take the right arguments.
2362 * Makefile.am: Increment shared lib revision number. I think
2363 sometimes the uninstalled Guile finds the installed shared lib;
2364 Gord says doing this might help. As things turned out, I can't
2365 say whether it does.
2366 * Makefile.in: Regenerated.
2368 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2369 passing it as the closure argument to scm_boot_guile. (Bill
2372 * ports.c (print_void_port, putc_void_port, puts_void_port,
2373 write_void_port, flush_void_port, getc_void_port, close_void_port,
2374 noop0): Use ANSI prototypes instead of K&R declarations, so the
2375 initialization of void_port_ptob gets aggressively type-checked.
2376 Fix arguments of print_void_port and write_void_port. (Bill

2410 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2412 * script.c (scm_find_executable): Use prototype-style definition
2413 here; apparently it's not quite right to have const in a prototype
2414 and then use a K&R declaration. I wonder if stuff like this will
2415 go away if we compile with -Wrequire-prototypes, or whatever that
2416 is... (Bernard URBAN)
2418 * scmhob.h: New text from Bernard URBAN.
2420 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2422 * script.c: Don't #define const on hpux. Configure takes care of
2423 this. (Thanks to Larry Schwimmer.)
2425 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2426 decide whether to #include <unistd.h>, instead of listing a bunch
2427 of systems. Don't #include stdio twice. Removed dyked-out
2428 definition of scm_find_impl_file.
2430 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2432 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2433 library version info to 1:0.
2434 * Makefile.in: Regenerated.
2436 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

2440 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2441 throw.c: Update copyright years; these files have been worked on
2442 significantly in 1997, but only had copyright years for 1996.
2443 Also, change name of copyright holder on some from Mikael
2444 Djurfeldt to Free Software Foundation; he has signed papers
2445 assigning the changes to the FSF.
2447 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2448 reason not to give the user the option.
2450 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2451 Return #f on end-of-file when scanning table (i.e. when called
2452 with no arguments). Try to catch errors, when we can.
2453 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2455 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2456 external declarations. These are useful.
2458 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2460 * posix.c: don't include <sys/select.h> or define macros for
2461 select, since they were not used in this file.
2463 * filesys.c (scm_select): make the fifth parameter microseconds,
2464 not milliseconds. let the fourth parameter be either a real value
2465 or an integer or #f. The first, second and third arguments can
2466 now be vectors: the type of the corresponding return set will be
2468 (set_element, get_element): new static procedures.
2470 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2472 * strports.c (scm_eval_string): New function.

2480 (scm_pipob): Use it in the initializer here.
2483 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2484 Use a meaningful error message when signalling an error. For
2485 this, scm_gethost must check h_errno rather than errno.
2487 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2489 * Makefile.in: Regenerated, using automake-1.1p.

2493 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2494 not SCM_UNSPECIFIED.

2498 (scm_shell): call scm_exit_status and exit on the result of the
2501 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2503 Ensure that shared substrings are handled properly when passed to
2504 a system call or other foreign function. Many thanks to Tim
2506 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2507 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2508 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2509 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
2510 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
2511 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2512 (scm_display_error_message): use RO macros when strings may be RO.
2513 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2514 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2515 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
2516 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
2517 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
2518 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
2519 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2520 scm_strftime), vports.c (scm_make_soft_port): use
2521 SCM_COERCE_SUBSTR to make sure shared substrings are

2526 * error.c (scm_error): Add newline to error message.
2528 * init.c (scm_init_standard_ports): Doc fix.
2530 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2532 * dynl-shl.c: Completely replaced with new code from Bernard
2535 * script.c (scm_ice_9_already_loaded): New variable.
2536 (scm_compile_shell_switches): Use it.
2538 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2540 * filesys.c (scm_input_waiting_p): add missing third argument to
2543 * stime.c (scm_localtime): copy the result of localtime before
2544 calling gmtime in case they share a buffer.
2545 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2548 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2550 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2552 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2554 * Makefile.am (check-local): New target, which causes 'make check'
2555 to run gh_test_c and gh_test_repl, with some trivial input.
2556 * Makefile.in: Rgnrtd.
2558 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2560 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2563 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2565 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2566 sure how this was supposed to work.
2567 (scm_async_click): don't send SCM_TICK_SIGNAL.
2568 (scm_init_async): don't initialize %tick-thunk.
2570 * the following change doesn't affect the Scheme interface:
2571 gc-thunk is called at the end of garbage collection. however it's
2572 no longer implemented by pretending it's a signal.
2574 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2575 system async corresponding to scm_gc_thunk.
2576 * async.h: declare scm_gc_async.
2577 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2578 gc-thunk directly, instead of going through a signal handler.
2579 (scm_gc_async): new variable, points to the GC system-async.
2580 (scm_init_async): save the GC async as scm_gc_async instead
2581 of using system_signal_asyncs.
2582 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2584 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2586 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2587 Don't screw up if we're interrupted.
2588 * Makefile.in: Regeneradet.
2590 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2592 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2594 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2595 we're not using AM_INIT_GUILE_MODULE any more.
2596 * Makefile.in: Reneregated.
2598 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2600 Functions for finding variable bindings, grace à Tim Pierce.
2601 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2602 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2604 Get 'make dist' to work again.
2605 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2606 * Makefile.in: Regenerated, like a surry without a fringe on top.
2608 Changes for reduced Guile distribution: one configure script,
2610 * configure.in, configure: Removed.
2611 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2612 real configure script lives.
2613 * Makefile.in, scmconfig.h.in: Regenerated.
2615 * init.c: #include "script.h", to get prototype for script.c's
2618 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2620 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2621 scm_must_malloc, not raw malloc.
2623 * script.c (scm_compile_shell_switches): Dyke out debugging output
2626 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2628 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2630 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2631 system has them. Hope this is safe. Previously
2632 sys/timeb.h was included if HAVE_FTIME was defined or if
2633 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2634 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2636 * ioext.c (scm_setfileno): add missing third argument to
2637 scm_misc_error call.
2639 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2641 * eq.c (scm_equal_p): Correctly compare strings of different
2642 varieties. (Thanks to Tim Pierce.)
2644 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2646 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2647 #! block comment must occur on a line all by itself.
2649 Move most of the guts of shell command processing into libguile,
2650 so guile.c can be very small (and eventuallly auto-generated. (I
2651 mean, generated mechanically, not self-generated. Hmm.))
2652 * guile.c, script.c, script.h: New source files.
2653 * init.c (scm_boot_guile_1): Call scm_init_script.
2654 * libguile.h: #include "script.h".
2655 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2656 targets, for new executable.
2657 (libguile_la_SOURCES): Mention script.c.
2658 (modinclude_HEADERS): Add script.h.
2659 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2660 not dynamic linking is enabled. This is because we're generating
2661 executables now. Move CY_AC_WITH_THREADS call after those, so the
2662 values of cy_cv_threads_libs captures the libs chosen above.
2663 * Makefile.in, configure, aclocal.m4: Regenerated.
2665 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2666 We don't maintain this interface any more, and it just confuses
2669 * alloca.c: #include <scmconfig.h>, not <config.h>.
2670 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2671 it'll get included in disties.
2673 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2675 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2676 be distributed, because they confuse people.
2677 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2679 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2681 * configure.in: check for presence of gethostent (not present on
2682 OpenBSD by default).
2683 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2684 * configure, scmconfig.h.in: Regenerated.
2686 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2688 * backtrace.c (scm_backtrace): Split message string across
2689 newlines properly. GCC is more tolerant of this than other
2692 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2694 Merge threads directory into libguile.
2695 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2696 threads.h: New source files.
2697 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
2698 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2700 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2701 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2702 coop-threads.c.cygnus, coop-threads.h.cygnus.
2703 * configure.in: If we're using threads, include threads.o in
2705 * _scm.h, libguile.h: threads.h lives in this directory now.
2706 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2707 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2708 currently used, but brought along for information's sake.
2709 * ChangeLog-threads: log from old 'threads' directory.
2710 * Makefile.in, configure: Rebuilt.
2712 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2714 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2717 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2719 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2721 Merge GH interface library into libguile.
2722 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2723 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2724 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2725 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2727 (EXTRA_libguile_la_SOURCES): ... here.
2728 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2729 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2730 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2731 New variables, describing how to build the gh test programs.
2732 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2733 build the test programs, and we probably should have been linking
2734 libguile.la against them all along, to support AIX shared libs.
2735 Add cflags for threads to CFLAGS; add libs for threads to new
2736 variable THREAD_LIBS, used in Makefile.am.
2737 * ChangeLog-gh: log from old `gh' subdirectory.
2738 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2740 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2742 * acconfig.h: Undo change of Apr 9; including the definition of
2743 PACKAGE in the guile headers conflicts with applications' own
2745 * scmconfig.h.in: Regenerated.
2747 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

2754 when PROC is receiving no arguments.
2756 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2758 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2759 have S_IFSOCK. This is the case under Ultrix.
2761 * posix.c (scm_status_exit_val, scm_status_exit_val,
2762 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2763 Ultrix versions of WIFSTOPPED, etc., which assume that their
2764 arguments are lvalues (hmm).
2766 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2768 * eval.c: Doc fixes.
2770 * throw.c: Doc fixes; rearranged.
2772 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2774 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2776 * acconfig.h: Added entry for PACKAGE.
2777 * scmconfig.h.in: Regenerated.
2779 Changes to work with automake-1.1n, which has better libtool support.
2780 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2781 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the

2785 * Makefile.in: Rebuild.
2787 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2789 * stime.c (scm_mktime): take an optional zone argument.
2790 (scm_localtime): check putenv return value.
2791 (scm_strftime, scm_strptime): moved from posix.c. move #include
2793 stime.h, posix.h: update prototypes.
2794 (bdtime2c, setzone, restorezone): new static procedures.
2795 (scm_mktime, scm_strftime): use them.
2796 (scm_strftime): don't call mktime before strftime. Use
2797 filltime for return value.
2798 (filltime): convert NULL zname to #f.
2799 (scm_strptime): return a count of characters consumed, not
2800 the remaining string.
2802 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2804 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2805 (scm_mktime): likewise.
2807 Uncomment localtime and mktime.
2809 * configure.in: add AC_STRUCT_TIMEZONE.
2811 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2813 * stime.c (scm_init_stime): don't define ticks/sec.
2814 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2815 return value problem and is still portable.)
2817 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2819 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2820 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2821 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2822 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2823 cpp_err_symbols.c): Corresponding changes.
2824 * Makefile.in: Regenerated.
2826 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2828 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2829 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2830 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2831 * putenv.c: new file, from sh-utils 1.12.
2833 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2834 since allocation isn't for Scheme objects.
2835 (scm_putenv): copy strings before placing in the environment.
2837 * stime.c (scm_current_time): throw an error if time returns -1,
2838 instead of returning #f.
2839 (scm_get_internal_real_time, scm_get_internal_real_time): use
2840 scm_long2num for return value instead of SCM_MAKINUM.
2842 * stime.h: prototypes updated.
2844 * stime.c (scm_time_in_msec): apparently unused, deleted.
2846 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2848 * configure.in: check for gettimeofday.
2850 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2851 which may be more usefully portable than a gettimeofday interface.
2853 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2855 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2857 * Makefile.in: Regenerated.
2859 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2861 * stime.c (filltime): recovered static procedure.
2862 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2865 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2866 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2868 * posix.c (scm_mknod): split the mode argument into type and perms
2869 arguments, like the extra fields returned by stat.
2871 * fports.c (scm_pipob): set the close, free and print procedures.
2872 (scm_close_pipe): new procedure.
2874 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2875 define them in boot-9.scm
2877 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2879 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2880 wan't defined. Don't include fd.h.
2882 * Previously fd.h was regenerated whenever configure was run,
2883 forcing a couple of files to be recompiled.
2885 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2886 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2887 Check for _fileno as well as _file.
2889 * ioext.c: don't fd.h.
2890 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2893 * Change the stratigy for getting information about errno
2894 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2895 generating lists of symbols during the build process, which will
2896 not always work, include comprehensive lists in the distribution.
2897 To help keep the lists up to date, the "check_signals" and
2898 "check_errnos" make targets can be used.
2900 * configure.in: don't check for a command to extract errno codes.
2901 * Makefile.am: update file lists, remove errnos.list and errnos.c
2902 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2903 check_errnos targets.
2904 (CLEANFILES): remove errnos.c and errnos.list, add
2905 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2906 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2907 * errnos.default: deleted.
2908 * cpp_signal.c: new file.
2909 * cpp_errno.c: renamed from errnos_get.c.
2910 * cpp_err_symbols, cpp_sig_symbols: new files.
2911 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2912 * error.c (scm_init_error): #include cpp_err_symbols instead of
2914 * posix.c (scm_init_posix): don't intern signal symbols. #include
2917 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2919 * strop.c (scm_i_index): allow the lower bound to be equal to the
2920 length of the string, so a null string doesn't always give an error.
2922 * posix.h: new prototypes.
2923 * posix.c (scm_status_exit_val, scm_status_term_sig,
2924 scm_status_stop_sig): new functions, as in scsh. They break down
2925 process status values as returned by waitpid.
2927 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2929 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2930 configure doesn't know about it.
2932 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2934 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2936 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2937 which defines C variables with global linkage.
2939 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2941 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2944 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2946 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2947 has time to check why this doesn't work well with continuations.
2949 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2951 * Fix shell syntax error; some shells won't tolerate
2952 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2954 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2956 * posix.c (scm_uname): throw an error if uname fails instead
2959 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2961 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
2964 * async.c (scm_ints_disabled): definition moved from error.c.
2966 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2968 * acconfig.h: Removed PACKAGE.
2970 * scmconfig.h.in: Regenerated.
2972 * snarf.h: g++ says it's non-portable not to specify the first
2973 argument in a varargs declaration. I introduced the first
2974 argument by using preprocessor conditionals.
2976 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2978 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2979 (scm_freopen): use RO string macros for filename and modes.
2980 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
2982 * posix.c (scm_getgrgid): simplify conversion of name to C string.
2983 (scm_mknod): use RO string macros for path.
2985 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2986 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2988 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2989 use SCM_ROSTRINGP and SCM_ROCHARS.
2991 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2993 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2996 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
2997 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
2998 support for byte vectors.
3000 * print.c (scm_iprin1): Limit number of vector elements printed
3001 according to pstate->length.
3003 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3005 * backtrace.c (scm_display_error_message): don't segv if message
3008 * error.h: prototype for scm_error_scm.
3010 * error.c (scm_error_scm): new procedure, reimplements scm-error
3011 in C and uses scm_error.
3013 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3015 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3016 pointer to the Scheme variable read-hash-procedures and intern it
3017 in scm_init_read. Modify scm_read_hash_extend and
3018 scm_get_hash_procedure to use the pointer.
3020 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3022 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3023 (SCM_KEYWORD_STYLE): defined.
3025 * read.c (scm_read_opts): add a keywords option. This isn't a
3026 boolean option, in case someone wants to add support for DSSSL
3028 Setup scm_keyword_prefix symbol.
3029 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3031 I've left keyword support disabled by default, since it doesn't
3032 seem to break the module system and it gives R4RS standard behaviour.
3033 It can be reactivated with (read-set! keywords 'prefix).
3035 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3037 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3038 before constructing arbiter.
3040 * eval.c (scm_m_define): Bugfix: Check that the object is a
3041 closure before setting the procedure property!
3043 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3045 * ports.c: Removed `ungetc-char-ready?'.
3047 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3049 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3050 (idea from Mikael: make it a pair so scm_permanent object only
3052 (scm_read_hash_extend): don't call scm_permanent_object.
3053 (ideas from Mikael): if chr is already in the list, replace its
3054 procedure instead of appending it again. If proc is #f, remove
3056 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3058 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3060 * gdbint.c (gdb_read): update scm_lreadr usage.
3062 * load.h: update prototypes.
3064 * load.c (scm_primitive_load, scm_read_and_eval_x,
3065 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3067 * read.h: add prototype for scm_read_hash_extend. Change args for
3070 * read.c (scm_read_hash_procedures): new variable.
3071 (scm_read_hash_extend): new procedure.
3072 (scm_get_hash_procedure): new procedure.
3073 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3074 for extended # processing.
3075 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3076 scm_read_token): remove case_i, sharp arguments. Change callers.
3078 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3080 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3081 (SCM_CASE_INSENSITIVE_P): define.
3083 * read.c: add case-insensitive option to scm_read_opts.
3084 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3085 to determine whether to convert symbol case.
3086 (default_case_i): definition removed.
3087 * read.c (scm_read_token): if case_i, downcase ic before doing
3090 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3092 * configure.in: Added configuration option `guile-debug'.
3093 Configure with --enable-guile-debug if you want a bunch of extra
3094 functions used for debugging when developing Guile.
3096 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3098 * procs.c (make-cclo): New undocumented debugging procedure: Make
3099 compiled closure with internal procedure PROC and length LENGTH.
3100 Only compiled if GUILE_DEBUG is defined.
3102 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3104 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3106 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3108 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3109 with 3 or more args internally to the evaluator.
3111 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3113 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3114 with 3 or more args internally to the evaluator. This is mainly
3115 because we don't want to pass entry and exit points of the
3116 debug support twice, but it also seems to increase the speed of
3117 the evaluator for such calls (e. g. (+ 1 2 3)).
3119 * backtrace.c (scm_display_application): New procedure:
3120 display-application; Set fancy printing parameters individually
3121 for different types of display (backtrace, error, application).
3122 (These should of course be customizable!)
3124 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3125 clear the CHECK-flags.
3127 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3129 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3131 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3133 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3134 from pairs with a GLOC in the car.
3136 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3137 otherwise `symbol-hash' will behave badly.
3138 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3139 we get segmentation fault!
3141 * symbols.c: Added #include "weaks.h". New functions:
3142 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3143 moved to an extraneous library when we split libguile.)
3145 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3147 * filesys.c (scm_stat): stat now takes fport arguments too as
3148 documented in the manual.
3150 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3152 * debug.c (scm_single_step): Bugfix: Call continuation with
3153 scm_call_continuation instead of throwing to it.
3155 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3157 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3158 argument wasn't declared to be optional.
3160 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3162 * stime.c (scm_init_stime): Add feature "current-time".
3164 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3166 * throw.h: prototype for scm_exit_status.
3167 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3168 args to derive an exit status. Allows (quit) to work from a
3170 (scm_exit_status): new function.
3173 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3175 * eval.c (scm_deval): Removed some old code.
3176 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3178 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3181 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3184 * procs.c: Introduce the existent C function scm_thunk_p at the
3185 Scheme level as well.
3187 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3189 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3190 used from C to easily lookup the value of a symbol in the current
3193 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3195 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3196 scm_init_unif in this file. This will also fix a previous problem
3199 * configure.in: Added AM_MAINTAINER_MODE
3201 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3203 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3206 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3208 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3209 source files that are not always included in libguile but should
3210 have their dependencies calculated by automake. This variable is
3211 recognized by automake, no further magic is needed.
3212 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3213 to deal exclusively with *.lo files, as it seems. The *.o files
3214 are built automatically when the corresponding *.lo file gets
3217 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3219 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3222 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3224 * unif.c (scm_array_set_x): minor change to argument error checking.
3226 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3228 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3229 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3230 They should only be included in the library at configure.in's
3232 (libguile_la_LDADD): Include the appropriate .lo files here.
3233 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3234 so we know when to build them (and their .lo bretheren).
3235 * configure.in (LIBLOBJS): New substituted variable. We let
3236 configure decide which .o files to include in LIBOBJS, and then
3237 put the corresponding list of .lo files in LIBLOBJS. The latter
3238 is what we pass to libtool.
3239 * Makefile.in, configure: regenerated.
3241 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3243 * symbols.c (scm_sysintern0): New function. Contains the core of
3244 old scm_sysintern but doesn't take a second value argument.
3245 (scm_sysintern): Now uses scm_sysintern0.
3246 (scm_sysintern_no_module_lookup): Renamed to
3247 scm_sysintern0_no_module_lookup and doesn't take a second value
3248 argument any longer.
3250 * symbols.h (scm_sysintern0: Added declaration.
3252 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3253 scm_sysintern when interning option keys. Otherwise we risk
3254 destroying the values of already interned variables.
3256 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3257 scheme-level boolean (use SCM_NFALSEP).
3259 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3261 (scm_backtrace): New function. (C version of old function from
3262 boot-9.scm) Motivation: Make it possible to display backtraces
3263 without depending on boot-9.scm. (I'm uncertain if this
3264 motivation is good enough...)
3266 * root.h (scm_root_state): Add member the_last_stack_var.
3267 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3269 * root.c (mark_root): Mark scm_the_last_stack_var.
3271 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3274 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3276 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3277 1. mark_lazy_catch didn't mark the smob.
3278 2. Both functions above have standard variants:
3279 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3280 free_lazy_catch --> scm_free0.
3282 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3284 * throw.c (scm_internal_lazy_catch): New function.
3285 (scm_lazy_catch): Rewritten to use it.
3286 (scm_ithrow): Handle the new lazy catch representation.
3287 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3288 that doesn't have a jmpbuf is a lazy catch clause.
3289 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3290 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3291 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3293 (scm_init_throw): Register the new lazy-catch smob type.
3294 * throw.h (scm_internal_lazy_catch): decl for new function.
3296 * throw.c (scm_internal_catch): Doc fixes.
3298 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3299 configure.in. Including this might cause problems if applications
3300 that link against libguile include their own copies of alloca, but
3301 if they're using autoconf, they should be adding libguile to LIBS
3302 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3303 the copy in libguile, and things will be okay. (I think.)
3305 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3307 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3309 strop.h: move prototypes too.
3311 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3313 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3316 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3317 etc. I deleted them from filesys.c long ago, but didn't
3318 notice they were here too (although ineffective since
3319 sys/stat.h wasn't included).
3321 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3323 * eval.c: Don't define alloca in GCC case. gcc will automatically
3324 use __builtin_alloca if appropriate.
3326 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3328 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3329 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3330 that values of automatic variables are preserved. See comments
3331 for safe_setjmp for details.
3333 Change from Thomas Morgan:
3334 * variable.c: Include eq.h.
3335 (var_equal): New function.
3336 (variable_smob): Use var_equal as the discriminator for variables.
3338 * throw.c (s_throw): Remove extraneous declaration.
3340 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3341 * eval.c: Add necessary CPP cruft to support that.
3342 * configure, Makefile.in, scmconfig.h.in: regenerated.
3344 Change from Thomas Morgan:
3345 * procprop.c (scm_procedure_properties): Convert the Scheme
3346 boolean returned by scm_procedure_p into a C boolean before using
3347 it as a condition for SCM_ASSERT.
3348 (scm_procedure_property): Likewise.
3350 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3351 indications of Unixness.
3354 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3356 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3358 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3360 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3361 "unknown # object" error messages.
3363 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3364 (scm_i_index) and declare it static. Add a 'direction' argument
3365 to indicate what way the search should go.
3366 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3368 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3369 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3371 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3373 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3375 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3376 to avoid clash with various scsh forks.
3378 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3380 The following two changes (ramap.c, throw.c) are motivated by the
3381 apparent unportability of forward declarations of static arrays of
3382 the form `static foo bar[];'.
3384 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3385 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3387 * throw.c (scm_throw): Moved above scm_ithrow.
3389 * options.h: Removed the extern declarations of scm_yes_sym and
3390 scm_no_sym since these are static.
3392 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3394 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3396 * Makefile.am: remove AWK=@AWK@.
3397 Add a rule for generating errnos.list.
3398 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3400 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3401 don't extract errnos, just set a variable (avoids the
3402 need to recompile error.c just because configure is run.)
3404 * unif.h: update prototypes.
3405 * unif.c (scm_uniform_array_read,write): change the offset and
3406 length arguments to start and end, for consistency.
3408 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3410 * ioext.h: update prototypes.
3411 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3412 scm_read_line_x, it's a more general procedure using an
3413 interface from scsh. read-line and read-line! are now defined
3415 Note that the new read-line trims the terminator
3416 by default, previously it was appended to the returned string. An
3417 optional argument specifies how to process the terminator (scsh
3418 compatible). For the old behaviour: (read-line port 'concat).
3419 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3420 returns a pair, but is converted to multiple values if the scsh
3423 socket.h: update prototypes.
3424 * socket.c (scm_recvfrom): for consistency with other procedures,
3425 take start and end as separate optional arguments.
3426 (scm_recv, scm_recvfrom): don't allow the second argument
3427 to be a size, only a buffer. Change the scheme names to
3428 recv! and recvfrom!. Don't return the buffer.
3430 * ioext.h, posix.h: move prototypes too.
3431 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3432 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3433 "read.h" and "unif.h".
3434 * ioext.c: include "chars.h"
3436 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3438 * dynl.c: The dynamic linking and module registration functions
3439 are now defined even when dynamic linking is not available for the
3440 host system. Some of their functionality can be done without
3441 dynamic linking; when it's really needed, they throw errors.
3443 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3445 * configure.in: Only define DYNAMIC_LINKING when one of the system
3446 dependent functions is detected.
3447 * dynl.c (scm_dynamic_func): New function to get the address of a
3448 function in a dynamic object.
3449 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3450 produced by scm_dynamic_func as the thing to call.
3452 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3454 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3455 (scm_register_module_xxx, scm_registered_modules,
3456 scm_clear_registered_modules): New functions.
3458 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3460 * symbols.c (scm_sysintern): Renamed to
3461 scm_sysintern_no_module_lookup.
3462 (scm_sysintern): New function to take the place of the old
3463 scm_sysintern. It uses the current toplevel lookup closure to give
3464 the symbol its value. This is a temporary hack to put packages
3465 like gtcltk into their own module.
3466 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3467 us whether `scm_top_level_lookup_closure_var' has been initialized
3469 * eval.c (scm_init_eval): Set it.
3471 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3473 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3474 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3476 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3478 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3479 scm_sys_dup): deleted: FD capability will be added to other
3481 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3482 scm_fd_free, fd_smob, scm_intern_fd.
3483 (scm_open): renamed from scm_sys_open. Return a port instead of
3484 an FD object. Make the mode argument optional.
3485 (scm_sys_create): deleted, it's just a special case of open.
3486 (scm_init_filesys): move interning of constants O_CREAT etc.,
3487 here (were previously using SCM_CONST_LONG macro).
3488 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3490 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3491 include "fports.h" and <stdio.h>
3492 (scm_stat, scm_select): don't support FD objects.
3494 * error.h: adjust scm_syserror_msg prototype.
3495 * error.c (scm_syserror_msg): take an extra argument for errno.
3496 Using the global value didn't always work, since it could be
3497 reset by procedure calls in the message or args arguments.
3499 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3500 I don't understand why the check was there (and what about the
3503 * strop.c (scm_string_copy): allow shared substrings to be copied.
3505 * unif.h: corresponding change to prototypes.
3506 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3507 recognize two new optional arguments: offset and length. Allow
3508 the port argument to be an integer (file descriptor, for scsh).
3509 Include <unistd.h> for "read" prototype.
3511 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3513 * socket.c: don't include filesys.h.
3515 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3517 * Makefile.am: add AWK=@AWK@ (?)
3519 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3521 Add a rule to generate errnos.c from errnos.
3522 * error.c (scm_init_error): include errnos.c.
3523 * errnos_cnvt.awk: new file, converts the list of errno codes to
3525 * errnos_get.c: new file.
3526 * errnos.default: new file, contains errnos to try if they can't
3527 be extracted from errno.h.
3528 * configure.in: if using GCC, try and extract errno codes from
3532 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3534 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3535 * Makefile.am: Made libguile into a libtool library.
3536 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3537 Set libtool_libs to indicate that libguile is a libtool library.
3538 See guile/ChangeLog for details.
3539 * .cvsignore: ignore "*.lo", the libtool library objects.
3541 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3543 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3544 use htons in getservbyport argument.
3546 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3548 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3549 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3552 * objprop.c (scm_object_property): No need to take the CDR of the
3553 value returned by scm_object_properties, since Aug 20 change.
3555 * configure.in: When checking for struct linger, #include
3556 <sys/types.h> as well as <sys/socket.h>. I've never known
3557 <sys/types.h> to cause any portability problems, and Solaris's
3558 <sys/socket.h> needs it.
3559 * configure: Rebuilt.
3561 I think the Sun compiler has chosen a perverse way to interpret
3562 ANSI declarations combined with K&R definitions. We'll
3563 appease it a little bit. But when it invades France, we fight.
3564 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3565 * print.h (scm_iprlist): Here too.
3566 * numbers.c (scm_divbigdig): Change definition to match
3567 declaration in numbers.h.
3568 * unif.c (scm_makflo): Change definition to match declaration in
3571 * init.c (scm_boot_guile): Don't return the value of
3572 scm_boot_guile_1. This function doesn't return a value;
3573 scm_boot_guile_1 doesn't return a value (or return at all).
3575 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3578 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3579 compile. I have a feeling this function is a bad idea anyway ---
3580 one should always test for features, not systems.
3582 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3583 semicolons. Only pure luck kept this from being noticed earlier.
3585 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3587 * socket.c (scm_recvfrom): Added missing semicolon.
3589 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3591 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3592 the buffer and start and end positions for scsh networking
3595 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3597 * configure.in: Revert previous change to this file; the problem
3598 is due to transient automake weirdness.
3599 * configure: Rebuilt.
3601 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3602 PLUGIN/guile.libs. configure generates the latter from the former.
3603 * Makefile.in: Rebuilt.
3605 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3606 need this if we install scripts, like guile-snarf.
3607 * configure: Rebuilt.
3609 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3611 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3613 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3615 * socket.c (scm_addr_vector): fix faulty scm_listify.
3617 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3619 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3620 style block comment is no longer considered an error.
3622 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3624 * PLUGIN/guile.libs.in: New file.
3625 * PLUGIN/guile.libs: Removed from repository.
3626 * configure.in: Create PLUGIN/guile.libs from
3627 PLUGIN/guile.libs.in. This is for including additonal libraries
3628 needed for dynamic linking.
3629 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3630 instead of PLUGIN/guile.libs.
3632 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3634 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3636 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3637 occurrences of the given element from the list, not just the
3638 first. This is how the Emacs Lisp functions behave, how the
3639 analogous Common Lisp functions behave, and (I believe) how the
3640 older Maclisp functions worked. I realize that this change may
3641 break code, but it seemed better to break it before the Guile
3644 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3645 Their prototypes were already present in gc.h, but they weren't
3647 (scm_init_storage): Initialize scm_protects.
3648 * root.c (scm_protects): New element of scm_sys_protects.
3650 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3652 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3654 * libguile.h: Added #include "libguile/net_db.h".
3656 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3657 30 change. That file is only meant for communication between the
3658 configuration process and load.c. If code linked against libguile
3659 wants to get at the paths mentioned in libpath.h, it can call
3660 functions declared in load.h.
3662 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3664 * libguile.h: Removed #include "libguile/fdsocket.h"
3666 * net_db.c: Added #include <sys/socket.h>.
3668 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3670 * filesys.c (scm_input_waiting_p): use select in preference to
3671 FIONREAD, since the latter doesn't detect EOF.
3672 Throw error if neither select nor FIONREAD available.
3674 * socket.c (scm_connect): take a port, not a fd object.
3675 (scm_fill_sockaddr): throw an error if fam is not recognised.
3676 (scm_bind): use scm_fill_sockaddr.
3677 (scm_listen): take a port, not a fd object.
3678 (scm_accept): take and return a port. return #f in the car if
3679 address can't be got
3680 (scm_sock_fd_to_port): new procedure.
3681 (scm_socket): use scm_sock_fd_to_port.
3682 (scm_addr_vector): throw error if unrecognised address type.
3683 take an extra argument with the calling procedure name.
3684 (scm_getsockname): take a port. return #f if address can't be got.
3685 (scm_getpeername): take a port. return #f if address can't be got.
3686 (scm_recvfrom): take a port. return #f for address component if can't
3688 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3689 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3691 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3693 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3694 use separate data pointers, to allow them to be designed
3695 independently and reused.
3696 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3697 Renamed from catch_body, catch_handler, and uncaught_throw; made
3699 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3701 (scm_catch): Use the above.
3702 (scm_throw): Don't bother printing a message for an uncaught
3703 throw; we establish a default handler in init.
3704 * throw.h (scm_internal_catch): Prototype updated.
3705 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3707 (struct scm_body_thunk_data): New structure, used as data
3708 argument to scm_body_thunk.
3709 * init.c (struct main_func_closure): New structure, packaging up
3710 the data to pass to the user's main function.
3711 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3712 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3713 scm_internal_catch to establish a catch-all handler, using
3714 scm_handle_by_message. This replaces the special-case code in
3716 (invoke_main_func): Body function for scm_internal_catch; invoke
3717 the user's main function, using the main_func_closure pointer to
3718 decide what to pass it.
3719 * root.c (struct cwdr_body_data): Remove handler_proc member.
3720 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3721 (cwdr_handler): Removed.
3723 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3725 * socket.h (SCM_P): update bind prototype.
3726 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3727 include "feature.h".
3728 (scm_socket): return a port, not a file descriptor object.
3729 include "fports.h" and <unistd.h>
3730 (scm_bind): take a port, not a file descriptor object.
3731 take an extra argument for address args.
3733 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3734 INADDR_NONE, INADDR_LOOPBACK.
3736 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3738 * init.c: include net_db.h and not fdsocket.h.
3739 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3741 * Makefile.am: corresponding changes.
3742 * socket.h: renamed from fdsocket.h, fix names.
3743 * net_db.h: renamed from socket.h, fix names.
3744 * socket.c: renamed from fdsocket.c.
3745 remove _sys from procedure names.
3746 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3747 add "socket" to features list.
3748 * net_db.c: renamed from socket.c.
3749 remove _sys from procedure names.
3750 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3751 add "net-db" to features list.
3752 include "net_db.h". don't include <sys/socket.h> or
3755 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3757 * tags.h (scm_tags): Removed comma at end of last enumerator.
3759 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3761 Don't use GCC extensions to allocate space for debugging frames.
3762 (Here he goes again! Why do we put up with this?!)
3763 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3764 an scm_debug_info structure, not an in-line array of them. Add
3765 'info' member, to say how many vect elements we've used, for eval
3767 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3768 a new variable debug_info_end to mark the end of vect, instead of
3769 the address of the 'info' pointer itself.
3770 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3771 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3772 (SCM_APPLY): Explicitly allocate space for debug.vect.
3773 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3774 * stacks.c: Adjusted for new debug frame structure.
3775 (RELOC_INFO, RELOC_FRAME): New macros.
3776 (stack_depth, read_frames): Use them, and new scm_debug_frame
3777 element 'info', instead of magically knowing that eval frames have
3778 an info pointer sitting after vect.
3779 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3781 (scm_init_stacks): Formatting tweaks.
3783 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3785 Give GCC more control flow information, so it can be sure that
3786 variables aren't used uninitialized.
3787 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3788 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3789 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3790 scm_misc_error): Tell GCC that these functions never return.
3791 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3792 out the field type, call abort if SCM_ASSERT returns, to placate
3794 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3795 scm_wta ever returns. We can't handle this case anyway, and this
3796 gives the optimizer more information.
3797 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3798 scm_wta ever returns.
3800 In some cases, the code is fine, but GCC isn't smart enough to
3801 figure that out; this usually happens when one variable is only
3802 initialized and used when a particular condition holds true, and
3803 we know that condition will never change within a given invocation
3804 of the function. In this case, we simply initialize the variables
3805 to placate the compiler, hopefully to a value which will cause a
3806 crash if it is ever actually used.
3807 * print.c (scm_iprin1): Initialize mw_pos.
3808 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3809 * throw.c (scm_ithrow): Initialize dynpair.
3810 * unif.c (scm_uniform_vector_ref): Initialize cra.
3811 * struct.c (init_struct): Initialize prot.
3812 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3814 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3815 if EXPR contains no expressions.
3817 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3819 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3820 cause an infinite loop (???). So much for the algebraic
3821 equivalency of variable-sized arrays and alloca...
3823 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3825 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3826 a SCM boolean, not a C boolean.
3828 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3830 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3831 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3832 rules for raising scm_mtrigger. Previously, unfortunate but not
3833 unlikely circumstances could result in almost constant invokation
3834 of the gc. Now, this situations should be less likely, but they
3835 are not prevented completely.
3837 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3839 * numbers.c (scm_fuck): Procedure removed; looks like old test
3841 * numbers.h: Prototype removed.
3843 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3845 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3846 array to a pointer, to match my Nov 21 change in eval.c.
3848 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3850 * libguile.h: Added #include "libguile/backtrace.h", #include
3851 "libguile/stacks.h".
3853 * strings.c (scm_string scm_make_string scm_string_ref
3854 scm_string_set_x scm_string_equal_p scm_string_append):
3855 Bugfix according to scm patch from Aubrey Jaffer:
3856 Corrected long-standing
3857 (not (eqv? (integer->char 128)
3858 (string-ref (make-string 1 (integer->char 128)) 0)))
3859 bug found by John Kozak <jk@noontide.demon.co.uk>.
3861 * strports.c, strports.h: Make scm_eval_0str return the value of
3862 the last expression evaluated (previously, it returned void).
3864 * strports.c, strports.h: New function: scm_read_0str. Does what
3867 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3869 * simpos.c (scm_getenv): return #f if string can't be found in the
3870 environment instead of throwing an exception, for compatibility
3871 with numerous other systems.
3873 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3875 * Makefile.am (.c.x): Use guile-snarf.
3876 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3878 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3880 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3882 * backtrace.c (scm_display_error_message): Made non-static, and
3883 renamed from display_error_message.
3884 * backtrace.h (scm_display_error_message): Added extern decl.
3885 * throw.c (uncaught_throw): Use it to display the error message.
3887 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3889 * inet_aton.c: Use #if 0, not #ifdef 0.
3891 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3893 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3894 to convert the returned value.
3895 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3896 the offset argument.
3898 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3900 Add new interface to catch/throw, usable from C as well as
3902 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3903 (scm_internal_catch): New function, replaces...
3904 (scm_catch_apply): Deleted.
3905 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3906 mechanism which is a bit more code, but can be used nicely from C
3907 and implement the Scheme semantics as well.
3908 (scm_internal_catch): This is the replacement; it's named after
3909 the analogous function in Emacs.
3910 (scm_catch): Reimplemented in terms of the above.
3911 (struct catch_body_data, catch_body, catch_handler): New
3912 functions, used by scm_catch.
3913 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3914 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3915 support for new cwdr.
3917 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3920 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3922 * acconfig.h: Added DYNAMIC_LINKING symbol.
3923 * configure.in: Add option and checks for dynamic linking.
3924 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3925 dynl.h: New files for dynamic linking support.
3926 * Makefile.am (libguile_a_SOURCES):
3928 (modinclude_HEADERS): Added "dynl.h".
3929 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3931 * init.c (scm_boot_guile_1): Call
3932 scm_init_dynamic_linking to initialize dynamic linking support.
3934 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3936 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3937 (as we Schemers say). It needs to be global, so that I can tweak
3938 it for the proper operation of unexec.
3939 (scm_boot_guile_1_live): New variable, see above.
3941 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3943 * guile-snarf.sh: Removed.
3944 * PLUGIN/guile.libs: Added dependency for -lm.
3945 * acinclude.m4: Renamed from aclocal.m4.
3946 * PLUGIN/greet: Removed.
3947 * Makefile.am, aclocal.m4: New files.
3948 * configure.in: Updated for Automake.
3950 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3952 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3953 and not top_level_lookup_thunk_var.
3955 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3957 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3959 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3961 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3962 Scheme function, instead of syntax. Single argument is now a
3965 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3967 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3968 scm_ra_divide): Properly terminate statements passed as arguments
3969 to IVDEP macros. (Thanks to Bernard Urban.)
3971 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3972 with non-constant sizes. (Thanks to Bernard Urban.)
3974 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3976 It's an "eval closure", not an "eval thunk." A thunk is a
3977 function of no arguments.
3978 * root.h (struct scm_root_state): Renamed
3979 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3980 (scm_top_level_lookup_closure_var): Renamed from
3981 scm_top_level_lookup_thunk_var.
3982 * root.c (mark_root): Uses changed.
3983 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3984 * init.c (scm_start_stack): Uses changed.
3985 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3986 Change scheme-visible name to *top-level-lookup-closure* from
3987 *top-level-lookup-thunk*.
3989 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3991 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3992 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3994 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3996 * gc.c (struct scm_heap_seg_data): Doc fixes.
3998 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3999 sweeping. Then, prepend each segment's free cells to its
4000 freelist, rather than wiping out the old value. (Thanks to Marius
4003 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4004 scm_check_freelist, scm_debug_newcell): New functions and
4005 variables, for debugging freelist problems.
4006 * pairs.h (SCM_NEWCELL): New debugging version added.
4007 * gc.h (scm_debug_newcell): Added extern declaration, used by
4008 debugging version of SCM_NEWCELL.
4010 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4012 On some systems <libc.h> conflicts with <unistd.h>, and should not
4013 be #included at all.
4014 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4015 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4016 * configure.in: Call it.
4017 * posix.c, filesys.c: Use its results to decide whether or not to
4019 * configure, scmconfig.h.in: Rebuilt with autoconf and
4022 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4024 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4025 pointer to the stdio stream before calling scm_setbuf0, so the
4026 latter will be able to retrieve it. I'm surprised this didn't
4027 segfault earlier. (Thanks to Christopher Lee.)
4029 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4031 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4034 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4036 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4037 number of stack narrowing specifier pairs. The first specifier in
4038 a pair controls inner border, the second the outer border. A
4039 number means cut that number of frames, a procedure object means
4040 cut until that object is found in operator position in a frame.
4042 * root.c (cwdr): Bugfix.
4044 * read.c: Recording of positions disabled by default.
4046 * procs.c (scm_closure_p): New function.
4048 * posix.c (scm_tmpnam): New function.
4050 * load.c: Added #include "throw.h".
4051 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4054 * load.c, load.h (scm_read_and_eval_x): New function.
4056 * eval.c: Renamed debug option "deval" to "debug".
4058 (scm_eval_x): `eval!' is no longer accessible from the scheme
4059 level. Motivation: We can't allow operations which introduce
4060 glocs into the scheme level. Guile's type system can't handle
4061 these as data. Use `eval' or `read-and-eval!' as replacement.
4063 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4064 SCM_CONSP since this is a macro!; Set vframe.prev to
4065 scm_last_debug_frame instead of 0. In this way we can look
4066 "above" the virtual start stack frame if we wish.
4067 (scm_debug_hang): New function: Useful for debugging Guile in
4068 certain tricky situations. Will probably be removed later...
4070 * debug.h: Changed semantics of debug option "backtrace". This
4071 option now only indicates whether we want automatic backtrace at
4074 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4076 * ports.c: #include "filesys.h"
4077 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4079 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4080 Motivation: This is system specific code which is related to file
4081 I/O. It also may use select. Added code by Gary Houston to
4082 detect presence of character in stdio buffers.
4084 * libguile.h: #include "libguile/libpath.h"
4086 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4087 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4088 SCM_SITE_DIR; Install libpath.h among the other include files.
4090 * load.c, load.h (scm_sys_package_data_dir): New function.
4092 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4094 * stacks.h: Bugfix: Don't use tail-array length field as stack
4095 length field! This screwed GC.
4097 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4099 * _scm.h: Added #ifndef around definition of macros min and max.
4101 * __scm.h: Added hooks for threads to plugin to in ints protection
4102 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4103 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4104 the main code in these macros duplicated and spread over multiple
4105 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4106 SCM_THREAD_SWITCHING_CODE.
4108 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4110 * snarf.h: New file.
4111 * guile-snarf.sh: New file.
4112 * Makefile.in (inner_h_files): Added snarf.h
4113 (ancillary, install, uninstall, distclean): Added actions for
4115 (.c.x): Use guile-snarf.
4116 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4117 (gen_c_files): Note that these depend on guile-snarf.
4118 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4119 now in "snarf.h". Added #include "snarf.h" to get them.
4120 * libguile.h: Added #include "snarf.h".
4121 (Patches applied and tweaked by Jim Blandy.)
4123 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4125 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4126 standards suggest against providing prototypes for system
4127 functions. Thanks to Greg Troxel.
4129 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4131 * strports.c (scm_eval_0str): New function.
4132 #include "read.h", to get prototype for scm_read.
4133 * Makefile.in (strports.o): Update dependencies.
4134 * strports.h: New prototype.
4136 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4137 scheme name from "int?" to "integer?". It seems to do the job.
4138 * numbers.h: Rename prototype too.
4139 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4142 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4143 scm_num_eq_p): Rename these according to R4RS conventions: call
4144 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4145 to making libguile R4RS compliant without ice-9...
4147 * load.c (scm_sys_search_load_path): Search for files under all
4148 extensions listed in the %load-extensions variable. If FILENAME
4149 is absolute, return it unchanged, without searching the load path.
4150 (scm_loc_load_extensions): New variable, pointing to
4151 %load-extensions' value cell.
4152 (scm_init_load): Initialize it, and the value it points to.
4153 (scm_primitive_load_path): Improve error reporting.
4155 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4156 of new Scheme variable %load-hook.
4157 (scm_primitive_load): Apply %load-hook to filename.
4159 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4161 * configure.in: add tests for figuring out whether buffered data
4162 is available in a FILE structure, which is needed by char-ready.
4164 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4167 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4168 exceptions using misc_error instead of syserror. It seems a bit
4169 odd to throw an exception if a string can't be found in the
4170 environment, but it's consistent with open-file, stat etc.
4171 (simpos.h): remove sys_ from getenv.
4173 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4174 occurs, throw an error instead of returning errno. Return value
4176 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4178 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4180 * filesys.c (scm_stat2scm): derive file type and permissions from
4181 the stat mode and append them to the returned vector.
4182 There isn't much overhead in doing this and it avoids the need to
4183 work with S_IRUSR et al. in Scheme.
4184 Define symbols scm_sym_regular etc.
4185 (scm_init_filesys): don't intern S_IRUSR etc.
4187 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4188 and s_primitive_load_path.
4190 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4192 * error.h: don't declare error symbols. prototype for scm_misc_error.
4194 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4197 * error.c: use SCM_SYMBOL to set up error keys.
4198 scm_misc_error: new procedure.
4200 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4202 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4203 between `#!' and `!#' is ignored.
4204 (skip_scsh_block_comment): New function.
4206 * feature.c (scm_set_program_arguments): New argument, FIRST.
4207 * feature.h: Update prototype.
4208 * init.c (scm_boot_guile_1): Pass new argument to
4209 scm_set_program_arguments.
4211 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4213 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4214 (scm_boot_guile): Call scm_set_program_arguments here, later than
4215 the old initialization.
4217 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4218 initialization procedure.
4219 - Delete in, out, err arguments; there are other perfectly good
4220 ways to override these when desired.
4221 - Delete result argument; this function shouldn't ever return.
4222 - Rename init_func argument to main_func, for less confusion.
4223 - Delete boot_cmd argument; main_func is more general.
4224 -Add 'closure' argument, to help people pass data to main_func
4225 without resorting to global variables.
4226 - Abort if reentered; don't bother returning an error code.
4227 - Call scm_init_standard_ports to set up the default/current
4228 standard ports; no need to pass them to scm_start_stack.
4229 - Remove code to evaluate the boot_cmd, and start the repl; let
4230 the user do something like that in main_func if they want.
4231 - Remove code to package up a return value; main_func can do any
4233 - Call exit (0), instead of returning.
4234 (scm_start_stack): Don't initialize the I/O ports here; that's
4235 weird. Delete in, out, err arguments. Move guts to
4236 scm_init_standard_ports, scm_stdio_to_port.
4237 (scm_init_standard_ports): New function, to set up current and
4238 default standard ports.
4239 (scm_start_stack, scm_restart_stack): Make these static.
4240 * init.h (scm_boot_guile): Adjust declaration.
4241 (scm_start_stack, scm_restart_stack): Remove externally
4242 visible declarations for these.
4243 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4245 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4246 written out several times in scm_start_stack.
4247 * fports.h: New declaration for the above.
4249 * feature.c (scm_set_program_arguments): New function.
4250 * feature.h: New declaration for the above.
4252 * ports.c: Formatting tweak.
4254 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4256 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4257 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4258 for obtaining the address of a car or cdr field. Motivation:
4259 &SCM_CXR make assumptions about the internal structure of the
4262 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4263 Motivation: see SCM_CXRLOC.
4265 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4266 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4267 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4268 Motivation: Safer use. Some other macros are defined in terms of
4269 these operations. If these are defined using the SCM_SETCXR
4270 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4271 to inefficiency and an <e1> with side-effects could potentially
4272 break. Also, these particular operations are heavily utilized in
4273 the garbage collector. In unoptimized code there will be a
4276 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4277 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4278 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4279 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4280 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4281 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4282 vports.c: Cleaned up use of pairs: Don't make any special
4283 assumptions about the internal structure of selectors and
4284 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4285 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4286 (Among other things, this change makes it easier to build Guile
4287 with certain compilers which have problems with casted lvalues.)
4289 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4291 * stacks.c: Improve selection of relevant stack frames when making
4292 a stack object. Introduce one level of indirection in the stack
4293 object to make it possible to "narrow" to a certain region of the
4294 stack. This facilitates making use of more clever algorithms (not
4295 implemented) for selecting relevant frames and gives a cleaner
4296 design since selection of frames can be done independently of
4297 extraction of frames from the real stack.
4298 (scm_stack_id): Also take #t as argument which means look at
4301 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4302 Turn n_tail into an integer directly representing current number
4303 of frames in stack. Add field tail.
4305 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4307 * debug.c (scm_make_memoized): Made it available at scheme level.
4308 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4309 SCM_NIMP before applying heavier predicates in argument checking.
4310 (scm_local_eval): Also take memoized object as argument.
4312 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4313 aren't created with zero length, but should such a strange
4314 creature suddenly turn up...
4316 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4318 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4319 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4321 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4323 * variable.c (scm_make_variable): Make the name hint optional, as
4325 (anonymous_variable_sym): Renamed from variable_sym. All uses
4328 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4329 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4330 of scm_primitive_load_path was also changed to
4331 "primitive-load-path", from "%try-load-path". Callers changed.
4332 We'd like to respect the convention that a function named
4333 "try-mumble" should behave just like the function called "mumble",
4334 but return #f instead of signalling some error.
4335 * load.h: Rename prototypes.
4337 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4339 * print.c (make_print_state, grow_print_state), print.h: Modified
4340 the print state representation: Don't use a tail array for
4341 recording of circular references. Resizing of the print state
4342 structure invalidates the print state pointer. To avoid passing
4343 around an indirect print state reference to all printing
4344 functions, we instead let the print state reference a resizable
4347 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4349 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4350 Don't crash when passed an improper list terminated by a
4351 non-immediate value.
4353 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4355 Allocate data for structures on an eight-byte boundary, as
4356 required by the tagging system.
4357 * struct.c (alloc_struct): New function.
4358 (scm_make_struct, scm_make_vtable_vtable): Call it.
4359 * struct.h (scm_struct_n_extra_words): Bump to 3.
4360 (scm_struct_i_ptr): New "field".
4361 * gc.c (scm_gc_sweep): When we need to free the data, use the
4362 information stored by alloc_struct to find the beginning of the
4363 block allocated to the structure, so we can free it.
4365 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4367 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4370 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4371 (scm_debug_info): New member: id.
4373 * stacks.c: Stacks are now represented as structs; Stacks have an
4374 id given to them by `start-stack'.
4375 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4377 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4378 Changed stack representation.
4380 * debug.c (scm_procedure_name): Try procedure property `name' for
4381 compiled closures aswell.

4387 objects. (Earlier, only closures were recorded.)
4389 * procprop.h: Added declaration of scm_i_name.
4391 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4392 (scm_make_gsubr): Record names of compiled closures.
4394 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4396 * debug.c, debug.h: Removed obsolete code.
4398 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4399 stacks.c: Renamed regs --> scm_contregs.
4401 * print.c (scm_free_print_state): Cleanup print state before
4402 returning it to pool. It is better to do it here than in
4403 scm_prin1 since scm_prin1 is called often.
4405 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4406 s_set_source_property_x): Check that first argument is a pair or a
4409 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4410 scm_i_line, scm_i_column and scm_i_breakpoint global.
4412 * init.c: Added #include "backtrace.h" and #include "stacks.h".

4423 backtrace.h, stacks.c and stacks.h.
4425 * symbols.c (scm_sym2ovcell): Fixed documentation.
4427 * _scm.h (min, max): Added.
4429 * async.c: Moved `min' macro to _scm.h.
4431 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4432 SCM_BACKTRACE_INDENT.
4434 * eval.c: Added new debug options `maxdepth' and `indent'.

4443 * print.h: Added declarations for scm_make_print_state,
4444 scm_free_print_state.
4446 * debug.c (scm_m_start_stack): New acro.
4448 * debug.h: Small cleanup.

4473 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
4474 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
4475 declare functions with prototypes. (Patch thanks to Marius
4478 More prototype-related changes from Marius Vollmer:
4479 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4480 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4481 * ports.h (ptobfuns): Added prototypes. This means some casting in
4483 * fports.c: Added casts for initializations, since the functions
4484 are defined to take FILE * as their stream argument, not SCM.
4485 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4486 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4487 to `char *str_data' to conform to prototype.
4489 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4491 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4493 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4495 * stime.c, stime.h: use SCM_P method.
4497 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4499 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4500 be given at least two arguments. Insist that lst's last element
4501 be a list, but don't make any requirements of its predecessors.
4503 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4505 * eval.c (scm_nconc2last): Revert last change; there seems to be
4506 other stuff going on here.
4508 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4510 * eval.c (scm_nconc2last): Make sure that each element of lst
4511 (which is a list of argument lists, except for the tail) is a
4512 proper list, i.e., finite and terminated by '().
4514 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4516 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4519 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4520 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4523 * vectors.c (scm_make_vector): Fill vectors with the undefined
4524 value, to help make Guile Scheme code more portable to other
4527 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4528 * symbols.h, tags.h: Doc fixes.
4530 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4532 * async.c (scm_take_signal): Doc fixes.
4534 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4536 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4537 want to subtract it from the modulus; we just want to leave it
4540 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4542 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4545 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4547 * throw.c (scm_catch_apply): Finished implementation of
4550 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4552 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4554 (scm_init_filesys): set "i/o-extensions" feature.
4557 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4559 * Makefile.in (root.o): Correct dependencies.
4561 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4563 * Makefile.in: Added dependency entry for root.o.
4565 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4566 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4568 * init.c (scm_start_stack): Set initial root continuation number
4571 * procs.c: New function: scm_thunk_p.
4573 * procs.h: Added declarations of scm_thunk_p.
4575 * root.c: Renamed `call-with-new-root' -->
4576 `call-with-dynamic-root'.
4577 (cwdr): Removed allocation of new root state. This should be done
4578 separately by use of scm_make_root.
4579 (scm_apply_with_dynamic_root): New function: Does what it
4580 sounds like. Needed when spawning threads.
4582 * root.h: Added member last_debug_frame to root state.
4583 Added #include "libguile/debug.h"
4585 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4586 arguments. The motivation is that code in root.c needs catch
4587 functionality, and we want to avoid code duplication.
4588 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4589 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4590 handlers that run without popping the stack into the dynwind
4593 * throw.h: Added prototypes for scm_catch_apply and
4596 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4598 * root.h (scm_root, scm_set_root): Decouple thread support details
4599 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4600 SCM_SET_THREAD_LOCAL_DATA.
4602 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4603 and tortoise scanning loop.
4605 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4607 * Makefile.in: Rebuild dependencies.
4609 * libguile.h: #include "libguile/print.h" before "smob.h", since
4610 the latter uses the print_state structure.
4612 * throw.c (scm_ithrow): Use the correct variable when checking to
4613 see if a given element of scm_dynwinds is a valid catch.
4615 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4616 structure, abort; don't just silently ignore the garbage.
4618 * _scm.h: #include "print.h" here, since it seems to be used just
4620 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4621 strports.c, unif.h: Don't #include "print.h".
4623 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4625 * feature.h (scm_loc_features): Removed external declaration.
4626 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4628 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4630 * feature.c (scm_init_feature): Added threads feature (needs to be
4631 initialized here, since features doesn't exist when
4632 scm_init_threads is called).
4634 * libguile.h: Added #include "libguile/../threads/threads.h".
4635 (This is a kludge to get thread support working. This should be
4638 * configure.in, acconfig.h: Added flags for thread support.
4640 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4643 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4644 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4647 * _scm.h: Added conditional #include "threads.h"
4649 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4650 SCM_THREADS_SWITCHING_CODE.
4652 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4653 allocate the basic dynamic root object.
4654 (scm_boot_guile): Added call to scm_init_root.
4656 * root.c, root.h: Added root smob.
4657 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4658 functions: Implements dynamic roots mostly according to spec in
4659 SCM manual. Main difference is that the second argument is a
4660 throw handler rather than an error "thunk".
4662 * root.h: Added declaration of scm_init_root.
4664 * root.c: Added #include "genio.h", #include "smob.h", #include
4665 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4667 (scm_init_root): Added #include "root.x".
4669 * throw.c: Added #include "stackchk.h"
4670 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4671 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4672 can be used in scm_call_with_new_root; Added reenabling of stack
4673 checking when catching a throw.
4675 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4677 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4679 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4680 element is not found, as per R4RS.
4682 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4684 * list.c: Doc fixes throughout.
4686 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4688 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4689 declare the char * to be const. Avoids a warning in rgx.c.
4691 * ports.h: spelling fix.
4693 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4696 * load.c (scm_sys_try_load_path): throw an error if file not found
4697 (like it says it in NEWS).
4699 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4701 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4702 PROPS slot to '(), not #f; it's an empty alist.
4704 * throw.h, throw.c: Use SCM_P instead of #if hair.
4706 Remove special support for uncaught throws; see throw.c for
4708 * throw.c (uncaught_throw): New function.
4709 (scm_ithrow): Call uncaught_throw if we don't find a throw
4710 target; don't mess with scm_bad_throw_vcell.
4711 (scm_bad_throw_vcell): Variable deleted.
4712 (scm_init_throw): Don't initialize it.
4714 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4717 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4719 * numbers.c (scm_istr2int): If the number is short (as most
4720 numbers are), just call scm_small_istr2int to deal with it.
4721 (scm_small_istr2int): New function, created by un-#ifdefing the
4722 non-bignum version of scm_istr2int and renaming it.
4724 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4726 * load.c (scm_sys_try_load): don't check whether value returned
4727 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4728 Change the Scheme name from %try-load to primitive-load.
4730 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4731 Can avoid passing a message, allowing it to be derived in the
4732 error handler (e.g., if we want to throw to the key both from
4735 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4737 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4738 references now have a new appearance which is more compact and
4739 also gives a clue about what the target of the reference is.
4740 By setting parameters in the print state, more fancy printing can
4741 be achieved. This is used by the (not yet commited) backtrace
4744 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4746 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4749 * print.c: Added #include "struct.h". Removed function
4752 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4753 scm_iprin1. Removed prototype for scm_prlist.
4755 * arbiters.c (prinarb),
4756 async.c (print_async),
4757 debug.c (prindebugobj, prinmemoized),
4758 eval.c (prinprom, prinmacro),
4759 filesys.c (scm_fd_print, scm_dir_print),
4761 mallocs.c (prinmalloc),
4762 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4763 smob.h (scm_smobfuns),
4764 srcprop.c (prinsrcprops),
4766 unif.c, unif.h (scm_raprin1, rapr1),
4767 variable.c (prin_var): Changed argument `int writing' to
4768 `scm_print_state *pstate'.
4770 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4771 that it will be called before scm_init_print.
4773 * print.c (scm_prin1): Print states are now allocated when calling
4774 scm_prin1 and then passed around to all printing functions as an
4775 argument. A cache `print_state_pool' enables reuse of print
4777 (scm_make_print_state): New function.
4778 (scm_iprin1): Adaption to print states.
4779 (scm_iprlist): An initial "hare and tortoise" scan brings down
4780 time complexity to O (depth * N). (Better time complexity will be
4781 achieved when the printing code is completely rewritten.)
4783 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4785 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4786 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4787 it gets done whether or not the cache variable has a value.
4789 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4791 Distinguish #f and ().
4792 * __scm.h: #undef SICP.
4793 * pairs.h (SCM_EOL): Delete this definition, equating it with
4795 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4796 the value it used to have. Doc fixes, too.
4798 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4800 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4801 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4802 Lord's implementation of structs, allowing for tail arrays as
4803 described in the manual. Also fixed some bugs. (Both the interface
4804 and the implementation should be improved.)
4806 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4808 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4809 People who whish to see the source can do `(print-enable 'source)'.
4810 Removed #ifdef DEBUG_EXTENSIONS.
4812 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4814 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4815 integer (assuming for now accepting an integer is a good thing).
4817 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4818 %S will be used instead for write'ing arguments.
4820 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4821 asserts. fix a few other asserts.
4822 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4823 scm_uniform_vector_ref, scm_array_set_x,
4824 scm_dimensions_to_unform_array): change args in
4825 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4826 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4827 scm_substring_fill_x): likewise.
4828 gsubr.c (scm_gsubr_apply): likewise.
4829 eval.c (SCM_APPLY): likewise.
4831 * eval.c (4 places): replace scm_everr with lgh_error or
4834 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4835 scm_memory_error): new procedures.
4836 scm_everr: deleted. can use scm_wta, dropping first two args.
4837 scm_error: convert NULL subr to SCM_BOOL_F.
4839 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4842 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4845 * error.c, error.h: new error keys: scm_arg_type_key,
4846 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4848 scm_wta: reimplement using lgh_error instead of scm_everr.
4850 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4852 * gdbint.c: scm_lread now has one more argument.
4854 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4855 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4856 loading source from non-file ports, which, e. g., happens when
4857 using the Emacs interface).
4859 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4862 * read.c: Added code for recording of positions of source code
4863 expressions; New functions: recsexpr, scm_lreadrecparen;
4864 _scm_make_srcprops --> scm_make_srcprops
4865 (scm_flush_ws): Removed updating of positions counters. This work
4866 is already done by scm_gen_getc
4868 * read.h: Added prototype for scm_lreadrecparen
4870 * print.c: Added #include "alist.h"
4872 * eval.c: Added #include "hash.h"
4874 * eq.c: Added #include "ramap.h"
4876 * options.c: Documentation fixes.
4878 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4879 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4880 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4881 --> scm_make_srcprops
4883 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4884 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4885 function calls in the definition of the whash access macros.
4887 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4889 * init.c (scm_boot_guile): Add level of indirection to
4890 scm_boot_guile_1() to ensure that stack base pointer is properly
4891 initialized. There was no guarantee that variable i was the
4892 highest/lowest variable on stack (i.e. the call frame of
4893 scm_boot_guile was not completely protected from gc).
4895 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4897 * ports.h (scm_port_table): put back file_name, it will be used to
4898 support debugging. Undo related changes in fports.c, ioext.c,
4901 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4903 * ports.h (scm_port_table): remove file_name member for now, it seems
4905 * fports.c (scm_open_file): don't set file_name in PTAB.
4906 (prinfport): don't use file_name in PTAB.
4907 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4908 * ports.c (scm_add_to_port_table): don't intialize file_name.
4909 (scm_port_file_name): remove for now.
4910 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4912 * fports.h (scm_mkfile): prototype deleted.
4913 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4915 * debug.c, unif.c: use scm_out_of_range instead of
4916 wta for range errors (ASSERT still needs work).
4918 * error.c, error.h (scm_out_of_range): new procedure.
4920 * error.c, error.h (scm_out_of_range_key): new key.
4922 * posix.c (scm_sync): #else was missing.
4924 * error.c, error.h: append _key to names scm_num_overflow and
4927 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4928 of consing an empty list.
4929 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4930 of macros, saves code and string space.
4931 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4932 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4933 lower case. Rename scm_syserror_m to scm_syserror_msg.
4934 error.h: prototypes for new procedures.
4936 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4938 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4940 * error.c, error.h: setup scm_num_overflow key.
4942 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4943 Remove definition of SCM_OVSCM_FLOW.
4945 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4947 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4948 explicit message and args.
4950 * error.c, error.h, __scm.h: change system_error_sym to
4953 * error.c (system_error_sym): remove leading %% from the Scheme name
4956 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4958 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4960 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4961 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4962 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4963 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4964 renamed. (These were introduced by unsupervised name
4967 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4969 * print.c: Added code for detection of circular references during
4970 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4971 a hook for printing of closures (accessible via print options).
4972 This leads to a split of calls to scm_iprin1 into two classes:
4973 elementary print operations (e. g. the code which prints a smob)
4974 still use scm_iprin1 while top level calls (like scm_display) use
4975 scm_prin1. scm_prin1 begins by clearing the data structure used
4976 to record reference information.
4978 * print.h: Added declarations of scm_prin1 and scm_prlist.
4980 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4982 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4984 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4986 * error.c (err_head): scm_iprin1 --> scm_prin1
4988 * debug.c: Adjusted header comment.
4992 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4994 * strerror.c: Doc fix.
4996 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4998 * gdbint.c (gdb_read): Now possible to run during GC.
4999 (unmark_port, remark_port): New functions.
5001 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5003 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5004 of allocating a new string object. Also, increase size by
5005 the factor 2 instead of 1.5.
5007 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5009 * __scm.h (SCM_P): Corrected to run under traditional C.
5011 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5014 * async.c: Calls to scm_sysintern corrected.
5016 * async.h (scm_async_clock): Redundant declaration removed.
5018 * continuations.c (scm_dynthrow): Redundant declaration removed.
5020 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5021 Definition typos corrected.
5023 * debug.h: Missing declarations of functions in debug.c added
5026 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5027 Missing declarations to functions in eval.c added.
5029 * filesys.c: Possibly uninitialized variable rv.
5031 * gc.h (scm_object_addr, scm_unhash_name): Missing
5032 declarations of functions defined in gc.c added.
5034 * genio.c: Possible typos str_data -> wstr_data. ???
5036 * genio.c: Possibly unintended shadowing of local variable
5037 `int c' (gotos out of scope of inner `c'). ???
5039 * init.c: Uninitialized `SCM last' may be used.
5041 * ioext.h: (scm_sys_isatty_p): Typo.
5043 * list.h (scm_list_head): Missing prototype for function in
5046 * numbers.c (scm_two_doubles): Changed from extern to static
5047 (is used only within numbers.c).
5049 * numbers.h: Repeated declarations removed.
5051 * ports.h (scm_close_all_ports_except): Declaration for the
5052 function defined in ports.c added.
5054 * posix.h: Missing declarations added.
5056 * procs.h (scm_make_subr_opt): Missing declaration added.
5058 * socket.h (scm_sys_gethost): Missing declaration added.
5060 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5062 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5063 Missing declarations added.
5065 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5067 * struct.c: Uninitialized variable `SCM answer' may be used.
5069 * unif.c (l2ra): Declaration prototype.
5071 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5072 defined in ramap.c).
5074 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5075 Redundant declarations removed (they are in ramap.h).
5077 * variable.h (scm_make_udvariable,
5078 scm_make_undefined_variable): Declaration corrected to
5079 correspond variable.c.
5081 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5082 Missing declarations added.
5084 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5086 * Makefile.in (distclean): Don't forget to delete fd.h.
5088 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5090 * fd.h.in, tags.h: Trivial cleanups.
5092 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5093 marksweep.h just declared functions from gc.c.
5094 * gc.h, libguile.h: Don't #include "marksweep.h".
5095 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5096 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5097 dependencies updated.
5099 * libguile.h: Don't #include "files.h"; it's been deleted.
5101 * files.c (scm_sys_delete_file): Moved to filesys.c.
5102 File is now empty; deleted.
5104 * filesys.c: scm_sys_delete_file is now here. Remove
5105 #if's; they seem to rely on remnants of an old portability
5106 regimen. If the problems come up again, solve them properly,
5107 using autoconf. Specifically: Don't test M_SYSV, and #define
5108 remove to be unlink if it's #defined; don't use remove just
5109 because HAVE_STDC_HEADERS is #defined.
5110 * filesys.h: Add declarations for scm_sys_delete_file.
5111 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5112 files.o, files.h, files.c, and files.x.
5113 * init.c: Don't #include "files.h", and don't call scm_init_files.
5115 Use SCM_P instead of PROTO; the latter intrudes on the user's
5117 * params.h: Deleted; definition of SCM_P moved to...
5118 * __scm.h: ... here, where it replaces PROTO macro.
5119 * libguile.h, smob.h: Don't #include "params.h".
5120 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5121 smob.h: Fix prototypes accordingly.
5122 * Makefile.in: Update dependencies.
5123 (inner_h_files): Remove params.h.
5125 * gc.c: #include "gc.h"; every module should include its header,
5126 to let the compiler cross-check the declarations against the
5129 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5130 simpos.h: #include "libguile/__scm.h".
5132 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5134 * init.c: Don't forget to #include smob.h and init.h.
5135 * Makefile.in: Dependencies updated.
5137 * smob.h: Use PROTO instead of #if __STDC__.
5139 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5141 * __scm.h: Doc fixes.
5143 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5144 <angles>; this allows `make depends' to work properly.
5146 * libguile.h: #include smob.h and pairs.h before the others; they
5147 define typedefs used by other headers.
5149 C files should #include only the header files they need, not
5150 libguile.h (which #includes all the header files); the pointless
5151 recompilation was wasting my time.
5152 * Makefile.in (all .o dependency lists): Regenerated.
5153 * libguile.h: Don't try to get a definition for size_t here...
5154 * __scm.h: Do it here.
5155 * _scm.h: Since this is the internal libguile header, put things
5156 here that all (or a majority) of the libguile files will want.
5157 Don't #include <libguile.h> here; that generates dependencies on
5158 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5159 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5160 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5257 * weaks.c: Get "weaks.h".
5259 * stackchk.h: #include "libguile/debug.h",
5261 * print.h, read.h: #include "options.h", since everyone who uses
5262 either of these files will need that.
5264 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5265 anyone who uses this file will need them to define the smob
5266 printing functions. Also, get markers.h, since people will need
5267 to #define the mark functions.
5269 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5270 * ports.h: ... to here.
5272 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5273 don't rely on archaic C default type rules.
5275 * fports.h: #include "libguile/ports.h", since you need that in
5276 order to parse this.
5278 * genio.h: #include "libguile/print.h", because you need that to
5279 parse this; don't bother #including "ports.h", since print.h gets
5282 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5284 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5285 this; it's now a reference to an element of *scm_root.
5287 * debug.h: Don't #include "options.h"; the compiler won't be able
5288 to find that once the headers are installed; instead, #include
5289 "libguile/options.h".
5290 * gc.h: Same, with marksweep.h.
5291 * mbstrings.h: Same, with symbols.h.
5292 * scmhob.h: Same, with _scm.h.
5293 * smob.h: Same, with params.h.
5295 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5296 C files; there's no need for this, and it forces recompilations
5299 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5301 * error.c (scm_error): declare scm_error_callback.
5303 * error.h: prototype for scm_error_callback.
5305 * __scm.h: define lgh_error.
5306 (SCM_SYSERROR): redefine using lgh_error.
5308 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5310 * error.c (scm_error): new procedure.
5312 * error.h: prototype for scm_error.
5314 * Makefile.in (install): install scmconfig.h from the current
5315 directory, not $(srcdir).
5317 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5319 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5320 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5321 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5322 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
5323 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
5324 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5325 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5326 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5327 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5328 vports.h, weaks.h: #include "libguile/__scm.h", not
5329 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5330 dependencies are within libguile properly.
5332 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5334 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5335 when scmconfig.h doesn't exist.
5337 * load.c (scm_sys_try_load): Correct spelling.
5339 * feature.c (scm_loc_features): Make this static.
5341 * Makefile.in (libpath.h): Omit trailing slash from path. We
5342 shouldn't require it of users, so why put it here?
5344 Move code to initialize and search %load-path from ice-9 to C
5345 code, so we can use the load-path to find the ice-9 boot code;
5346 this makes it easier to run Guile without installing it. See
5347 corresponding changes in guile/Makefile.in.
5348 * feature.c: Move stuff concerned with the load path to load.c.
5349 (scm_compiled_library_path): Deleted.
5350 Don't #include libpath.h here.
5351 * feature.h: Don't mention scm_compiled_library_path.
5352 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5353 <sys/stat.h>, and <unistd.h> (if present).
5354 (R_OK): #define if the system hasn't deigned to.
5355 (scm_loc_load_path): New variable.
5356 (scm_init_load_path, scm_sys_search_load_path,
5357 scm_sys_try_load_path): New functions.
5358 (scm_init_load): Initialize scm_loc_load_path to point to the
5359 value cell of the Scheme %load-path variable.
5360 * load.h: Add declarations for scm_sys_search_load_path,
5361 scm_sys_try_load_path.
5362 * init.c: Call scm_init_load_path.
5363 * Makefile.in (feature.o, load.o): Dependencies updated.
5365 * load.c, load.h: Rewrite using PROTO macro.
5367 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5369 * gc.c (scm_cellp): New function: C predicate to determine if an
5370 SCM value can be regarded as a pointer to a cell on the heap.
5372 * gc.h: Added declaration of scm_cellp.
5374 * gdb_interface.h: New file: The GDB interface header from the GDB
5377 * gdbint.c: New file: GDB interface.
5379 * gdbint.h: New file: GDB interface.
5381 * libguile.h: Added #include <libguile/gdbint.h>.
5383 * init.c (scm_boot_guile): Added scm_init_gdbint.
5385 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5386 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5387 found if object files and source are kept separate).
5389 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5391 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5393 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5395 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5396 TK_SRC_DIR; they're not relevant any more.
5398 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5399 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5401 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5403 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5404 search path, so we can find the <libguile/MUMBLE.h> headers.
5406 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5408 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5409 implicit in the .c.o rule.
5410 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5413 Put the library path in a header file, instead of passing it on
5414 the command line in every compilation.
5415 * Makefile.in (libpath.h): New target.
5416 (feature.o): Depend on libpath.h.
5417 (clean): Delete libpath.h.
5418 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5419 * feature.c: ... #include "libpath.h" here.
5420 * .cvsignore: Ignore libpath.h.
5422 Don't install the unwashed masses of Guile header files in the
5423 main #include path; put most of them in a subdirectory called
5424 'libguile'. This avoids naming conflicts between Guile header
5425 files and system header files (of which there were a few).
5426 * Makefile.in (pkgincludedir): Deleted.
5427 (innerincludedir): New variable; this and $(includedir) are enough.
5428 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5429 (installed_h_files): Divide this up. Now this variable lists
5430 those header files which should go into $(includedir) (i.e. appear
5431 directly in the #include path), and ...
5432 (inner_h_files): ... this new variable says which files appear in
5433 a subdirectory, and are referred to as <libguile/mumble.h>.
5434 (h_files): List them both.
5435 (install): Create innerincludedir, not pkgincludedir. Put
5436 the installed_h_files and inner_h_files in their proper places.
5437 (uninstall): Corresponding changes.
5438 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5439 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5440 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5441 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5442 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5443 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5444 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5445 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5446 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5447 vports.h, weaks.h: Find __scm.h in its new location.
5448 * __scm.h: Find scmconfig.h and tags.h in their new locations
5449 (they're both "inner" files).
5451 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5453 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5455 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5457 * posix.c: Doc fixes.
5459 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5461 * socket.c: Don't include a prototype for inet_aton; just use a
5462 K&R style declaration, to avoid warnings but minimize the chance
5463 of conflicts with the system.
5465 On NextStep, <utime.h> doesn't define struct utime, unless we
5466 #define _POSIX_SOURCE before #including it.
5467 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5468 * acconfig.h: New comment text for above CPP symbol.
5469 * configure.in: Call it.
5470 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5472 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5474 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5475 testing for __EMX__.
5477 * posix.c: #include <libc.h>, if it exists.
5479 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5480 don't even know if the latter exists.
5482 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5483 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5484 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5486 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5488 (scm_init_posix): Use them when initializing the Scheme constants
5491 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5493 * Makefile.in (libdir, includedir, bindir): Use the
5494 autoconf-supplied values, instead of deriving them ourselves.
5495 (pkgincludedir, datadir, pkgdatadir): New variables.
5496 (install, uninstall): Put the header files in a special
5497 subdirectory, not in the main search path.
5499 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5500 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5502 * Makefile.in (IMPLPATH): Deleted; never used.
5504 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5505 on the Tcl/Tk source any more.
5506 (INCLUDE_CFLAGS): Remove references to the above.
5508 * Makefile.in (version.o): Corrected dependencies.
5510 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5512 * libguile.h: #include "version.h"
5514 * init.c (scm_boot_guile): Call scm_init_version.
5515 * gscm.c (gscm_run_scm): Call scm_init_version.
5517 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5518 GUILE_VERSION): AC_DEFINE these.
5519 (acconfig.h): #undef the above symbols.
5521 * Makefile.in (libobjs): Add version.o.
5522 (installed_h_files): Add version.h.
5523 (c_files): Add version.c.
5524 (gen_c_files): Add version.x.
5525 (version.o): New rule.
5526 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5527 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5528 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5529 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,

5533 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5534 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5535 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5536 weaks.o): Add version.h to dependency lists.
5537 (markers.o): Remove duplicate rule.
5539 * version.h: New file.
5541 * version.c: New file.
5543 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5545 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5546 array; use it appropriately. Since GCC is quite happy to
5547 subscript functions, it never warned us about this; we should use
5548 -Wpointer-arith in the future. I guess we never tested
5551 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5553 * socket.c: Doc and copyright fixes.
5555 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5557 * debug.c: Fixed and improved gdb support.
5559 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5561 * socket.c: Added declaration of inet_aton to avoid compiler
5562 warning. (Hope this solution is correct.)
5564 * stime.c: Added declaration of ftime. (This is missing in
5567 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5569 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5571 * Makefile.in (c_files): add strerror.c.
5573 * strerror.c: new file from Emacs' sysdep.c.
5574 maybe configure should also check for sys_errlist.
5576 * configure.in (AC_REPLACE_FUNCS): add strerror.
5578 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5580 * debug.c (scm_init_debug): Added initialization for
5581 scm_evaluator_traps.
5583 * debug.h, debug.c: Various name changes.
5584 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5585 "debug-options-interface". See commentary in options.c.
5587 * options.h, options.c: Options now have documentation strings.
5588 Also added a long explanatory commentary.
5590 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5593 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5594 last_debug_info_frame is now updated in all cases.
5596 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5599 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5601 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5602 Added option STACK_CHECKING.
5604 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5606 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5608 * __scm.h: Removed symbols for debugging support.
5610 * acconfig.h: Added symbols for debugging support.
5612 * configure.in: Added user option for debugging support.
5613 --enable-debug will include the debugging code into libguile.a.
5615 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5616 scm_relocate_chunk_to_heap.
5618 * debug.c: New file: low-level debugging support. It also
5619 includes support for debugging with gdb. (The extensions to gdb
5620 are written by Per Bothner at Cygnus.)
5622 * debug.h: New file: low-level debugging support.
5624 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5625 argument pairs. Extensive modifications to the debugging
5626 evaluator. Added "SECTION:" commentaries to clarify what happens
5627 when, during double compilation. Renamed EVALIMP --> EVALIM.
5628 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5629 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5630 the beginning of the file. New procedure: scm_unmemocopy.
5631 Added some global state variables needed by the debugging
5632 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5633 check_entry, check_apply, check_exit, debug_options and
5634 evaluator_traps. New acro: undefine.
5636 * eval.h: Renamed EVAL --> XEVAL.
5638 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5639 --> scm_make_weak_key_hash_table.
5641 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5642 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5644 * libguile.h: Conditionally include debug.h
5646 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5647 scm_object_properties shouldn't return handle. `handle' now gets
5648 initialized in scm_set_object_properties_x. scm_object_properties
5649 doesn't any longer create an entry in scm_object_whash.
5651 * options.c: New file: handling of run time options.
5653 * options.h: New file: handling of run time options.
5655 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5657 * print.c: New procedure: scm_print_options
5659 * print.h: Defines for print options.
5661 * read.c: New procedure: scm_read_options
5663 * read.h: Defines for reader options.
5665 * root.h: Added scm_source_whash among scm_sys_protects.
5667 * srcprop.c: New file: source properties.
5669 * srcprop.h: New file: source properties.
5671 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5672 (Bug found by A. Green.)
5674 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5676 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5678 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5680 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5682 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5683 and should be called by the final client.
5685 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5687 * gc.h: Use the PROTO macro when declaring functions.
5688 * gc.c: Use the PROTO macro when declaring static functions.
5689 Remove the CPP hair around function definitions.
5691 * gc.c (scm_init_storage): Initialize scm_asyncs.
5693 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5694 preprocessor symbol; "__scm.h" is where it might get #defined.
5695 * __scm.h: Similar: #include <scmconfig.h> before testing
5698 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5700 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5702 * init.c (scm_boot_guile): Add init_func argument; call
5703 (*init_func) instead of calling scm_appinit; it's ucky to
5704 hard-code names for the user's procedures.
5705 * init.h (scm_boot_guile): Adjust declaration.
5707 * __scm.h (PROTO): New macro, for declaring functions with
5710 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5711 eliminate all the __STDC__ conditionals.
5712 (scm_boot_guile): Add declaration.
5713 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5714 Remove __STDC__ conditionals around function definitions; the
5715 declarations in init.h will provide the same information, more
5718 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5719 complain about it in the error message; the error message is
5720 adequate without that note, and there's nothing the user can do
5723 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5725 * Makefile.in (ancillary): Drop def.sed.
5727 * posix.c (scm_init_posix): Use numeric values, rather than
5728 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5729 F_OK. The symbols aren't available on some systems, and I'm
5730 pretty sure their values are fixed by common widespread practice.
5731 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5733 More functions unavailable on some systems.
5734 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5735 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5737 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5738 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5739 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5740 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5741 stub that signals an error as the #else.
5743 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5745 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5747 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5749 * unif.c: include ramap.h.
5751 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5753 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5755 * ports.c: include sys/ioctl.h.
5757 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5759 * configure.in: check for sys/ioctl.h.
5761 * ports.c: include <malloc.h> not "malloc.h".
5763 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5765 * fports.c: remove ttyname and tmpnam declarations.
5767 * posix.c: fewer ttyname declarations.
5769 * fports.c: include <string.h> not "string.h".
5771 * init.c, ioext.c: include string.h and unistd.h.

5797 Changes for NeXT, suggested by Robert Brown.
5798 * configure.in: Call AC_TYPE_MODE_T.
5799 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5800 NeXT. Put header file list in alphabetical order.
5801 * configure, scmconfig.h.in: Regenerated.
5802 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5804 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5807 * acconfig.h: New file, providing documentation for the CPP
5808 symbols defined in configure.in
5809 * acconfig-1.5.h: Removed; superceded by the above.
5811 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>

5834 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5835 This is necessary on Ultrix, and doesn't hurt portability.
5837 * Makefile.in (dist-dir): New target, implementing a new dist system.
5838 (installed_h_files): Put in alphabetical order.
5839 Remove duplicate entries for markers.h and unif.h.

5845 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5847 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5848 every if must have an else, or else the whole command has a
5849 non-zero exit code whenever the if's condition is false.
5851 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>

5916 matter so long as it is non-0 (got rid of "* 4").
5918 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5920 * gscm.h: gscm_mkarray eliminated (presumably was not being used
5921 since its definition was bogus).

5925 * mallocs.[ch]: back again (for rx at least).
5927 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5929 * ports.c: removed functions relating to the mapping between ports
5930 and descriptors. (That stuff is unix-specific and should be collected

5938 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5939 handled correctly (SCM_FREEP was applied to them) -- test for
5940 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

6108 initialization to fix a race condition.
6110 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

6134 set the multi_byte flag correctly in symbols. This is wrong.
6135 intern_obbary_soft and msymbolize should take an extra parameter.
6136 Also, weird multibyte symbols don't print correctly.
6137 The weird symbol syntax is also a bit bogus (emacs doesn't quite
