1 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
3 * strings.c (scm_string_set_x): Require the argument to be a
4 writable string, not a substring or a symbol.
5 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
7 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
9 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
11 * eval.c (safe_setjmp): Remove this misunderstanding.
12 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
15 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
17 * libguile.h: Mark these as C declarations, for compilation by C++
20 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
21 __cplusplus clause. I seriously doubt this ever worked the way
22 the author seems to have intended.
24 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
26 Utterly needless cleanups to hopelessly messy code.
28 (scm_fflush): Moved to ...
29 * genio.c (scm_fflush): ... here, amongst all the other port
30 method invocation functions.
31 * genio.h, ports.h: The prototype moves too.
33 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
35 * backtrace.c (display_error_body): The current frame does not
36 always have a parent frame; consider a function called directly
37 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
40 * alloca.c (alloca): Undo yesterday's changes, and simply call
41 malloc directly for storage, and abort if we don't get what we
42 want. The situation is much simpler --- just call malloc. Emacs
43 has bizarre/evil requirements (signal handlers might malloc unless
44 you set this global flag, so you have to set the flag around all
45 calls to malloc) which we are certainly not going to conform to,
46 so we can do the simple and obvious thing.
48 * coop.c (coop_condition_variable_wait): Make this function
49 static. It's only useful internally --- you should never just
50 wait on a condition variable.
51 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
53 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
55 * unif.c (scm_array_set_x): Accept any kind of number as an
56 element for a uniform vector of doubles. This is more consistent
57 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
59 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
60 works; I can't conveniently test it myself. (Thanks to Dvid
61 Tillman for the bug report.)
65 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
66 from here, not from scm_compile_shell_switches (which is a pretty
68 (scm_load_startup_files): New function.
69 (scm_ice_9_already_loaded): Variable moved to here from script.c.
70 * script.c (scm_compile_shell_switches): Don't load the startup
72 (scm_ice_9_already_loaded): Variable moved.
73 * init.c (scm_load_startup_files): Prototype for new function.
74 * gh_init.c (gh_enter): Doc fix.
76 1998-10-03 <jimb@savonarola.red-bean.com>
78 Some anti-warning changes from Greg Harvey.
79 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
80 warnings when it doesn't understand our NORETURN declarations in
82 * posix.c (scm_mknod): Similar.
84 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
86 * posix.c (scm_getpwuid): If we can't find an entry, return our
87 own message, instead of using scm_syserror --- the getpwMUMBLE
88 functions don't set `errno' to anything interesting.
90 1998-10-03 <jimb@savonarola.red-bean.com>
92 Get rid of warnings from the cooperative threading system.
93 * threads.h (scm_single_thread_p, scm_yield,
94 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
95 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
96 scm_wait_condition_variable, scm_signal_condition_variable): Add
97 prototypes for these Scheme-visible functions.
98 * coop-defs.h (coop_next_runnable_thread,
99 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
100 Prototypes for these here, even though they're from iselect.c.
101 (coop_condition_variable_wait, coop_join): Add prototypes.
102 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
103 scm_threads_free_condvar): Make these smob functions static.
104 * coop-threads.h (coop_init): Give this a real prototype.
105 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
106 (coop_next_runnable_thread): No need to provide prototype; it's in
109 * scmconfig.h.in: .detarenegeR
111 * iselect.c, threads.c: Doc fixes.
113 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
115 * Makefile.in: Regenerated with a patched automake, to get
116 dependency generation right when using EGCS.
118 * inet_aton.c (inet_aton): Add prototype, to remove compiler
119 warning. (Thanks to Robert Pluim.)
121 * inet_aton.c (inet_aton): Reassure the compiler that the
122 arguments to the <ctype.h> macros are all unsigned characters, not
125 1998-10-03 <jimb@savonarola.red-bean.com>
127 Getting rid of more warnings...
128 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
129 today's change to ../configure.in.
130 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
131 * scmconfig.h.in: Regenertaded.de.,.__
132 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
133 (scm_localtime, scm_mktime): Use a const char * to manipulate the
136 * readline.c: Doc fix.
137 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
138 * readline.h (scm_filename_completion_function): Add prototype.
139 (scm_init_readline): Make this into a prototype.
141 * readline.c (scm_filename_completion_function): Use SCM_PROC to
142 declare this, instead of calling scm_make_subr manually.
144 1998-10-02 <jimb@savonarola.red-bean.com>
146 * readline.h (scm_init_readline): Add prototype for this.
147 (scm_init_readline): Make this a real prototype.
149 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
151 Warning fixes from Maciej Stachowiak:
152 * backtrace.h (scm_display_application, scm_backtrace): Add
154 * debug.c (scm_m_start_stack): Make this function static.
155 * fluids.h (scm_fluid_p): Add prototype.
156 * procprop.c (scm_i_procedure_arity): Make this function static.
157 * regex-posix.c (scm_regexp_error_msg): Make this function static.
158 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
159 * root.h (scm_dynamic_root): Add external prototype.
160 * scmsigs.h (scm_usleep): Add external prototype.
161 * script.h (scm_init_script): Use prototype, not K&R decl.
162 * stacks.h (scm_stack_id): Add external prototype.
163 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
165 1998-09-30 Mark Galassi <rosalia@cygnus.com>
167 * gh.h: took out the definitions of vset and vref, since they are
168 replaced by the proper vector routines that correspond to the R4RS
171 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
173 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
174 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
175 third argument, a C expression that should result in a SCM value,
176 which is used to initialize the variable. Reimplemented
177 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
180 * version.h (scm_libguile_config_stamp): Add prototype.
181 (From Maciej Stachowiak.)
183 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
185 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
186 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
188 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
190 * print.c (scm_iprin1): Rather than having one i, and using it in
191 several places, declare a fresh i local to each block where it is
192 used, and give it a signedness appropriate to its use in each case.
195 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
198 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
199 signed/unsigned clashes.
201 * posix.h (scm_tmpnam): Added prototype.
203 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
204 scm_make_subclass_object): Add external prototypes.
206 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
207 comparison is okay here.
209 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
211 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
212 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
214 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
217 * load.c (swap_port): Make this function static.
219 * load.c (scm_search_path): Make max_path_len and max_ext_len
220 unsigned, since they're compared against string sizes.
222 * load.c (init_build_info): Make i unsigned.
224 * ioext.h (scm_read_line): Add prototype.
226 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
227 scm_hash_fn_remove_x): Make hash bucket index local variable k
228 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
229 accurately as possible.
231 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
232 comparisons, and range checking to make sure those casts are
235 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
236 signed/unsigned comparisons.
238 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
239 avoid signed/unsigned comparisons.
240 * smob.h (scm_numsmob): Change extern declaration to match.
242 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
243 avoid signed/unsigned comparisons.
244 * ports.h (scm_numptob): Change extern declaration to match.
245 (scm_current_load_port, scm_set_port_line_x,
246 scm_set_port_column_x): New prototypes.
248 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
249 test code, and it causes warnings.
251 * gh.h (gh_int2scmb, gh_uniform_vector_length,
252 gh_uniform_vector_ref): Added prototypes.
254 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
255 debugging support unconditionally. That's backtrace.c, stack.c,
256 debug.c, and srcprop.c.
257 (EXTRA_libguile_la_SOURCES): Omit those from here.
258 * Makefile.in: Regenerated.
260 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
262 * options.c (scm_options): Bugfix: Allow empty list of options!
264 * debug.c, debug.h (scm_single_step): Removed.
265 (scm_with_traps): New procedure. This procedure could easily be
266 written in Scheme but needs to be highly optimized.
268 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
270 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
271 Check SCM_TRAPS_P before trapping.
273 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
275 Changes to avoid signed/unsigned comparison warnings.
276 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
277 (scm_gc_sweep): Make n and j local to the blocks they're used in,
278 so they can have appropriate types for each application. Make i
279 signed. Use initializers in some spots. I'll probably pay for
281 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
282 (scm_must_realloc): Make nm unsigned.
283 (init_heap_seg): Make new_seg_index and n_new_objects signed.
284 (scm_init_storage): Use prototype-style definition, and make the
286 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
287 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
289 * filesys.c (scm_readlink): Make local vars rv and size ints, to
290 avoid signed/unsigned comparison warnings, and because the return
291 value of readlink may be -1. Don't bother casting the third
292 argument to readlink.
294 * filesys.c (scm_dirname, scm_basename): Move these to their own
295 page, at the end of the file.
296 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
298 * eval.h (scm_eval_options_interface): Add external prototype for this.
299 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
301 * eval.c (scm_lookupcar1): Make this static.
303 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
304 Make these prototype declarations, not K&R-style.
306 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
307 unsigned comparison warning.
309 * appinit.c: File removed. It had a single function in it, empty,
310 whose reason for existence is explained in no documentation or
311 comment. I think it's there as a default for some Tcl-style
312 initialization, but Tcl abandoned that approach a while ago.
313 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
314 (BUILT_SOURCES): Remove appinit.x.
315 * Makefile.in: Regenerated.
317 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
319 * Makefile.in: Regenerated using the last public version of
320 automake, not the hacked Cygnus version.
322 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
324 Remove Totoro kludge.
325 * Makefile.in, scmconfig.h.in: Regenerated.
326 * init.c, readline.c: Don't check if TOTORO is #defined.
328 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
330 * Makefile.am: Adjust for new thread configuration system.
331 (INCLUDES): Include the value of THREAD_CPPFLAGS.
332 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
334 (THREAD_LIBS): Definition deleted; automake will generate such
335 things automatically.
336 * Makefile.in: Regenerated.
338 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
340 Simplify smob and port marking; set the mark bit in the generic
341 marking code, and make marker routines only responsible for
342 turning up outgoing pointers.
343 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
344 before calling the marking function. Don't call the marking
345 function if it's zero.
346 * markers.c (scm_mark0): Just return #f. This function isn't
347 necessary at all now, but it's harmless to call it. We'll leave
348 it in so other folks' code doesn't croak at link time.
349 (scm_markcdr): Don't call SCM_SETGC8MARK.
350 * async.c (mark_async): Don't call SCM_SETGC8MARK.
351 * dynl.c (mark_dynl_obj): Same.
352 * root.c (mark_root): Same.
353 * srcprop.c (marksrcprops): Same.
354 * unif.c (markra): Same.
355 * variable.c (scm_markvar): Same.
356 * ports.c (scm_markstream): Same.
357 (void_port_ptob): Specify zero for our marking function.
358 * debug.c (debugobjsmob): Same.
359 * dynwind.c (guardsmob): Same.
360 * filesys.c (dir_smob): Same.
361 * fluids.c (fluid_smob): Same.
362 * fports.c (scm_fptob, scm_pipob): Same.
363 * mallocs.c (mallocsmob): Same.
364 * regex-posix.c (regex_t_smob): Same.
365 * smob.c (freecell, flob, bigob): Same.
366 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
367 * throw.c (jbsmob, lazy_catch_funs): Same.
369 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
371 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
372 scm_copy_tree on code in order not to let memoized code to leak
373 out. Thus, scm_copy_tree needs to copy vectors as well since
374 quasiquote can introduce evaluated code also inside vector
377 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
379 * eval.c (scm_copy_tree): Removed ability to copy vectors.
381 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
382 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
385 * unif.c: Say that ivect and uvect are of type signed and unsigned
386 long instead of int in commentary so that it correctly describes
389 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
391 * stime.c: Removed declaration of strptime. (It should be
392 declared by the system headers. If it turns out that some systems
393 don't, we'll handle that then.) (Thanks to Greg Troxel.)
395 * stime.h: Renamed TIMEH --> STIMEH
397 * backtrace.c (scm_display_error, scm_display_backtrace): In order
398 to increase portability, don't use structure assignment.
399 (Thanks to Nicolas Neuss.)
401 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
403 (finalize_fd_sets): Added empty statement after last case label.
404 (Thanks to Nicolas Neuss.)
406 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
409 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
411 * init.c, readline.c: OK, I won't have these readline.x bug
412 reports anymore. We've had them since April. The current reason
413 is a completely unintelligible failure of totoro.red-bean.com to
414 do the test for rl_getc_function in libreadline correctly. This
415 kludge overrides the test if we're on totoro so that the snapshot
416 generation process can work.
418 * readline.c: Define a strdup replacement if not existent on system.
420 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
422 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
423 This change makes scm_make_vector R5RS compatible. We cannot keep
424 the third argument since people want to be able to deduce the form
425 of the C function call only by looking at R5RS. (At the same time
426 we have removed some unnecessary complexity!)
428 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
429 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
430 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
431 argument in call to scm_make_vector.
433 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
435 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
436 This macro is useful in applications.
438 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
440 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
441 (scm_parse_path, scm_search_path): New Scheme level procedures.
443 * load.h (scm_internal_parse_path, scm_parse_path,
444 scm_search_path): Declared.
446 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
448 * filesys.c (dirname, basename): New procedures.
450 * init.c (scm_boot_guile_1): Removed condition around
453 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
454 new data type (guards) for representation of C level guards and
455 data on the wind chain.
456 (scm_internal_dynamic_wind): New function.
458 * dynwind.h: Declare scm_internal_dynamic_wind.
460 * root.h (scm_root_state): Added scm_cur_loadp.
462 * root.c (mark_root): Added comment about cur_loadp.
464 * load.c: #include "dynwind.h";
465 (scm_primitive_load): Use scm_inner_dynamic_wind to update
468 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
470 * ports.c (current-load-port): New procedure.
472 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
474 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
475 not a tty, return #f.
477 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
478 to Julian Satchell and Roland Kaufmann.)
480 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
481 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
483 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
485 * debug.h, debug.c (scm_start_stack): New function. Implements
486 the guts of old scm_m_start_stack.
488 * debug.c (scm_m_start_stack): Use scm_start_stack.
490 * init.c (scm_start_stack, scm_restart_stack): Renamed to
491 start_stack and restart_stack. (These have static scope.)
493 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
495 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
496 readline functions to come in release 2.3. (Thanks to Chet
498 (handle_errors): Use the above functions.
500 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
502 * readline.c: Improvements for readline support: Handle errors
503 better; Implement before-read-hook.
505 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
507 * init.c (scm_boot_guile_1), readline.c: Test for
508 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
509 assure that we have version >= 2.1.)
511 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
513 * readline.c (scm_readline): Defer interrupts while we're calling
516 * readline.c (scm_add_history): Bugfix: Do strdup before giving
517 away the string to add_history.
518 (completion_function): Do completion for readline. (Thanks to
520 (scm_filename_completion_function): New procedure: Filename
522 (current_input_getc): New function. Use this one instead of
523 standard getc from readline.
525 * throw.c, throw.h (scm_handle_by_throw): New function: This
526 handler throws errors to next handler on the dynwind chain.
528 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
530 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
533 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
535 * procprop.c (scm_i_procedure_arity): New function. Returns arity
537 (scm_procedure_properties): Modified to return arity together with
539 (scm_procedure_property): Added the read-only property `arity'.
540 (scm_set_procedure_property_x): It is an error to set the `arity'
543 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
544 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
546 * procprop.h (scm_sym_arity): New symbol.
548 * objects.c (scm_set_object_procedure_x): New procedure: Use this
549 to set the dispatch procedure of an operator or entity object.
551 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
552 Made procedure slots read-only.
554 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
555 scm_tcs_cons_gloc case in zero args switch; Fixed args
556 construction for operators in scm_tcs_cons_gloc case in two args
559 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
561 * fluids.c: Removed use of assert.h (in order to avoid
564 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
566 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
568 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
569 change makes the evaluator safer at the cost of evaluation speed.
570 It handles the case when the user has added a non-immediate
571 improper end of the application form, e.g., `(+ 0 . x)'.
572 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
573 minimize the extra cost as much as possible. The new code is
574 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
575 problem with structs planted directly in the code (e.g. by a
576 macro). This no longer causes segmentation fault. (Thanks to
579 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
580 arg `proc' in order to be able to throw errors; New argument
583 * Removed extra #include "debug.h"
585 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
587 * scmsigs.c: Declare usleep as returning void on some systems.
588 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
591 * coop.c (usleep): Return void on some systems.
593 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
595 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
597 * coop.c: Changed return type of usleep to int.
599 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
600 isn't found in the OS.
602 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
603 isn't enabled. (Thought that I had made this change ages ago...)
605 * iselect.c: Declare bzero if not defined by OS.
607 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
609 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
610 condition. (Thanks to John Tobey.)
612 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
613 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
616 * __scm.h: Start the long-term project of moving to POSIX threads.
617 Phase 1: Classification of all critical sections.
618 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
619 for A sections. (See comments in __scm.h for details.)
621 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
622 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
624 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
626 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
627 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
628 (libpath.h, versiondat.h): Replaced dependency on Makefile with
629 dependencies on $(srcdir)/Makefile.in
630 $(top_builddir)/config.status in order to avoid circularity.
632 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
633 from argc if argc was 0 initially.
635 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
636 in generation of libpath.h.
638 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
640 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
641 libguile from 2 to 3.
643 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
645 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
647 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
649 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
650 scm_set_port_column_x, scm_port_filename,
651 scm_set_port_filename_x): Removed optional arguments. Added
652 proper argument checking.
654 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
655 stack size in machine words.
657 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
658 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
659 to Ole Myren Röhne.)
661 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
663 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
664 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
666 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
669 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
670 procedure apply: Copy argument lists before pushing them unto the
671 environment so that the environment won't get mutated due to
672 manipulation of procedure arguments. This should perhaps be
673 regarded as a temporary solution until someone finds a more
674 efficient one. (Thanks to Maciej Stachowiak.)
676 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
678 * script.c (scm_compile_shell_switches): Use "guile" as default
679 zero arg if argc is NULL.
681 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
683 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
684 is zero. (Thanks to Dirk Herrmann.)
686 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
688 * ports.c (scm_add_to_port_table): First line is now line 0
689 (was 1). (Interface changed according to suggestion by Per
692 * backtrace.c (display_header): Add 1 to line and column numbers
693 when presenting them to the user.
695 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
696 from debug.c --> eval.c
698 * eval.h, eval.c (scm_eval_options_interface): New options
700 (SCM_EVAL_STACK): New option: Size of newly created stacks,
701 i.e. stacks for new threads.
703 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
705 * eval.c (unsafe_setjmp): Removed with #if 0.
707 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
710 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
711 to avoid compiler warnings.
713 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
715 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
717 * throw.c (handler_message): Print message on current error port
718 instead of default error port. (Thanks to Maciej Stachowiak.)
720 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
722 * ports.c (scm_add_to_port_table): allocate in units of
723 struct scm_port_table *, not struct scm_port_table.
724 * posix.c (scm_close_pipe): remove the port from the port table
726 Thanks to Rob Engle for both fixes.
728 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
730 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
731 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
733 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
735 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
737 * backtrace.c (display_error_body, display_backtrace_body),
738 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
739 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
740 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
741 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
744 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
745 don't receive the jmpbuf arg anylonger.
746 (scm_catch): Don't accept a #f tag.
747 (scm_throw): Check that key is a symbol.
748 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
750 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
752 * async.c (async_pending): Removed declaration.
754 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
756 * dynwind.c (scm_wind_chain): New debug function.
758 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
759 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
760 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
761 extra layer of functions around the body and handler of a thread.
762 This extra layer makes sure that the handler is called in the
763 dynamic context of the surround (= empty dynwind list), but under
764 the *dynamic root* of the body. We can not use the dynamic root
765 of the surround since that root belongs to another thread => stack
766 is not handled correctly. It may seem ugly to use this extra
767 layer, but the extra cost in terms of execution time is really
768 negligible compared to the total amount of time required to create
769 a thread, and it would reduce maintainability to duplicate the
770 crucial and complicated steps performed by cwdr.
772 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
773 (SCM_ALLOW_INTS): Added thread switching code before interrupts
774 get re-enabled. The important effect of this is that interrupts
775 are blocked during thread switching so that thread data structures
776 don't risk getting messed up by an unfortunate signal.
777 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
778 seems to do more aggressive optimization which actually move
779 instructions around in these macros in a fatal way. Therefore:
780 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
781 just superstitious...)
782 (SCM_TICK): Maybe do a context switch and take care of asyncs.
783 This macro should be used instead of SCM_ASYNC_TICK since the
784 latter doesn't do context switches any more.
786 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
787 instead of SCM_ASYNC_TICK.
789 * coop.c, iselect.c: Since thread switches are now performed with
790 interrupts masked, we can't use the old mechanism of delivering
791 signals immediately when they arrive. Signals must instead be
792 delivered when the asyncs run *after* the end of the critical
793 section in scm_internal_select. But this also means after context
794 switch so that the signal will be delivered to a different thread.
795 To avoid this, I have changed the protocol of
796 coop_wait_for_runnable_thread and friends so that they are allowed
797 to return the original thread. So, if a signal arrives during
798 scm_internal_select, we won't any longer be forced do a context
799 switch, but can remain in the same thread and deliver the signal
802 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
803 scm_asyncs_pending and made it global.
805 * iselect.c: Small fixes.
807 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
808 coop_condition_variable_init, coop_condition_variable_wait,
809 coop_condition_variable_signal): Changed return type from `void'
810 to `int'. This is to adhere closer to the pthreads interface.
811 This, in turn, is part of an attempt to provide C versions of the
812 mutex and condition variable primitives which can be part of a
813 frontend to COOP or pthreads.
815 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
816 coop_condition_variable_destroy): New functions.
818 * coop-threads.c (scm_wait_condition_variable): Use
819 coop_condition_variable_wait_mutex.
821 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
822 Definitions moved to coop-defs.h.
824 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
825 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
826 scm_cond_destroy): New C interface to mutecis and cond vars.
828 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
830 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
832 * iselect.c: Now several threads can wait on the same file
833 descriptor. The behaviour is compatible with OS select: All
834 threads waiting for the fd return with the same status.
836 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
838 * coop-threads.c, threads.h (scm_spawn_thread): New function.
839 Can spawn a thread from application C code.
841 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
843 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
844 gh_doubles2scm): New functions.
846 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
848 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
849 commented-out version of gh_eval_str()
851 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
853 * socket.c (scm_bind): free soka after use.
855 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
857 * stime.c (tzvar): new variable.
858 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
859 avoid memory leaks when allocating.
861 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
863 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
866 * gc.c, tags.h: Doc fixes.
868 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
870 * eval.c (macro-eval!): Removed. This function was a design bug.
871 It allowed memoized code to leak out to the scheme level. Most
872 things that you could do with `macro-eval!' can be done with
875 1997-12-20 Tim Pierce <twp@skepsis.com>
877 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
878 scm_fgets now depends on ftell(3) to know how many bytes were
881 1997-12-15 Tim Pierce <twp@skepsis.com>
883 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
884 dealing with strings.
886 1997-12-13 Tim Pierce <twp@skepsis.com>
888 Make %read-line more suitable for implementing read-line efficiently.
889 * ioext.c (scm_read_line): Strip the terminating newline from a
890 string, and return a cons of the string and its terminator.
892 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
893 of the string that is read is stored in this memory location.
894 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
895 * genio.c, genio.h (scm_do_read_line): Update caller.
896 * ports.h (scm_ptobfuns): Update typedef.
897 * fports.c (scm_fptob, scm_pipob): Update struct.
899 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
901 * filesys.c (set_element): Return file descriptor.
902 (fill_select_type): Return the highest file descriptor.
903 (scm_select): Tell select about the highest file descriptor. On
904 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
905 Therefore the extra overhead for calculating the maximum fd seems
906 to be more than compensated. Is this correct? In any case,
907 scm_internal_select will be much faster with this info.
908 (scm_select, fill_select_type, set_element): Don't accept any kind
909 of object in the file descriptor list or vector.
911 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
913 * iselect.c (finalize_fd_sets): Bugfix.
915 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
917 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
918 when using scm_internal_select (since we might switch to another
921 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
923 * simpos.c (scm_system): always define: use sysmissing if not
924 available. Check for HAVE_SYSTEM instead of _Windows (does
925 Windows lack system or does it have an unusable one?).
926 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
927 Let the argument be optional: if not supplied, call system(NULL).
929 * ports.c (scm_close_port): relax the type check from OPPORTP to
930 PORTP; closing a closed port is allowed.
932 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
934 * fports.c (scm_fgets): Return if the last char in a chunk is
935 newline. When fgets returns a string whose length is `size-1', it
936 is ambiguous whether a whole line was retrieved, so we must check
937 explicitly whether a line terminator is present.
939 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
941 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
942 before taking the CDR. (Thanks to Harald Meland.)
944 * filesys.c (scm_stat): Slightly optimized.
946 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
948 * ports.c (scm_close_port): Make sure the port is open before
951 * guile-snarf.in: Pass args through to gcc in a way that preserves
952 whitespace boundaries. (Thanks to Greg Badros.)
954 1997-12-02 Tim Pierce <twp@skepsis.com>
956 * stacks.c (scm_frame_procedure): Reverse the logic in the return
957 statement. (Thanks to Doug Evans for pointing this out.)
959 1997-12-01 Tim Pierce <twp@skepsis.com>
961 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
963 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
965 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
966 errno macro expansion of this field name. (errno is a C
967 preprocessor macro on some systems.)
969 1997-11-29 Tim Pierce <twp@skepsis.com>
971 * iselect.c: Doc fix.
973 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
975 * init.c (scm_start_stack): Removed initialization of
976 scm_the_last_stack_var.
978 * backtrace.h: Declare scm_the_last_stack_var.
980 * backtrace.c: Define scm_the_last_stack_var.
982 * root.c (mark_root): Don't mark the_last_stack_var.
984 * root.h (scm_root_state): Removed the_last_stack_var.
986 * throw.c: Added #include "fluids.h"
987 (ss_handler): `the-last-stack' is now a fluid.
989 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
990 --> the_last_stack_fluid.
992 * backtrace.c: Added #include "fluids.h"
993 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
994 (scm_backtrace): `the-last-stack' is now a fluid.
996 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
997 after scm_init_fluids.
999 1997-11-28 Tim Pierce <twp@skepsis.com>
1001 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1003 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1004 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1006 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1008 * iselect.c (coop_next_runnable_thread,
1009 coop_wait_for_runnable_thread): Disable interrupts so that no
1010 async is executed before a potential error_revive.
1011 (scm_internal_select): Disable interrupts during the parts of the
1012 code which manipulate the sleep queue and the file descriptors.
1014 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1016 * Makefile.am: Added iselect.c and iselect.h.
1018 * coop.c (coop_qinit): Initialize fields used by
1019 scm_internal_select.
1020 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1021 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1022 replacement in iselect.c.
1023 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1024 coop_join): If GUILE_ISELECT enabled, use
1025 coop_wait_for_runnable_thread instead of
1026 coop_next_runnable_thread.
1027 (usleep, sleep): New replacements for system functions if
1028 GUILE_ISELECT is enabled.
1030 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1032 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1034 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1035 iselect.h. Implement Scheme level `select' using
1036 scm_internal_select. (See NEWS.)
1038 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1040 * init.c: Call scm_init_iselect.
1042 * iselect.h, iselect.c: New files. Implements
1043 scm_internal_select. (See NEWS.)
1045 1997-11-27 Tim Pierce <twp@skepsis.com>
1047 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1048 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1049 and scm_must_free, since ultimately the string returned will be copied
1050 by scm_makfrom0str anyway. Also, read any characters that may have
1051 been pushed onto the port with scm_ungetc.
1052 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1053 * ioext.c (scm_read_line): Free string after Guilifying it.
1054 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
1056 1997-11-26 Anthony Green <green@hoser.cygnus.com>
1058 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1060 * gh.h: Safely wrap prototypes for c++ usage.
1062 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1064 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1065 gh_repl (argc, argv).
1067 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1069 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1070 and to invoke scm_shell().
1071 (gh_launch_pad): took out the loading of boot-9.scm from here,
1072 since it is probably best to let the user control that. In fact,
1073 gh_repl() now invokes scm_shell() which does that.
1075 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1077 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
1080 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
1082 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
1083 yesterday's underscore patch. (Thanks to Marius Vollmer for
1086 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
1088 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
1089 DLSYM_ADDS_USCORE is not defined.
1091 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
1093 * gh_data.c (gh_uniform_vector_length):
1094 (gh_uniform_vector_ref): started implementing the uniform types in
1097 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1099 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1100 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1102 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1104 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1105 configure.in was changed).

1109 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1110 * Makefile.in: Regenerated.
1112 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1114 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1115 OPORT is an `open' port, not an output port.
1117 * filesys.c (scm_close, set_element, get_element, scm_chown,
1118 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

1122 scm_port_column, scm_set_port_column_x, scm_port_filename,
1123 scm_set_port_filename_x, scm_port_mode,
1124 scm_close_all_ports_except, scm_set_current_output_port,
1125 scm_set_current_error_port): Likewise
1126 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1127 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1129 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1130 * backtrace.c (display_backtrace_body): Likewise
1131 * fports (scm_setvbuf): Likewise
1132 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

1135 * unif.c (scm_uniform_array_write): Likewise
1137 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1139 Minor problems with substring-related tag changes.
1140 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1141 exactly what we want to leave in to detect substrings.
1142 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1143 * tags.h: Fix diagrams and comments describing the S tag bit;
1144 remove vestigial remarks about the D tag bit.
1145 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1146 * strings.c: Formatting tweaks.
1148 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1149 variable first; then SCHEME_LOAD_PATH, with a warning message.
1150 (scm_parse_path): New function.
1151 * script.c: Doc fixes.
1153 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1155 Readline support, from Daniel Risacher.
1156 * readline.c, readline.h: New files.
1157 * init.c: #include "readline.h".
1158 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1159 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1160 * Makefile.in: Regenerated.
1161 * scmconfig.h.in: Regenerated, after change to ../configure.
1163 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1165 * gh.h: gh_vector_set -> gh_vector_set_x
1167 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1169 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1170 with the ! -> _x mapping when going from Scheme to C.
1172 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1174 * gh.h (gh_reverse):
1182 (gh_assoc): added these gh_ functions implemented as macros.
1184 * gh_predicates.c (gh_null_p):
1185 (gh_string_equal_p): added these two missing predicates.
1187 * gh_list.c (gh_append):
1192 (gh_set_cdr_x): added these routines as I go through and try to
1193 complete the picture R4RS functions that should be mirrored in the
1196 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1198 * tags.h (scm_tc7_substring): Changed the comment and code to
1199 conform with the changes below. Folks! We have suddenly two new
1200 free tc7 codes!!! Jummy, jummy!
1202 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1204 * Makefile.in: Rebuilt.
1205 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
1207 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
1208 * unif.c (scm_vector_set_length_x): Don't handle multibyte

1224 (SCM_TYP7D): Removed.
1225 (scm_tc7_mb_string): Removed.
1226 (scm_tc7_mb_substring): Removed.
1227 * print.c (scm_iprin1): Handle char printing directly. Don't
1229 Don't include "mbstrings.h".
1230 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1231 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1233 Don't include "mbstrings.h".
1234 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1235 (SCM_SYMBOL_SLOTS): Define as 4.
1236 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
1237 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
1238 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
1239 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
1240 struct.c, threads.c, throw.c, unif.c, variable.c: Use new

1257 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
1258 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
1260 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1262 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1264 * gh_test_c.c (c_vector_test): some improvements on the vector
1267 * gh.h (gh_vector): this used to exist but do the wrong thing.
1268 Now it (almost) does the right thing, though it takes a list
1269 instead of the individual arguments. I need to see how it could
1271 (gh_list_to_vector): added this function as a macro. Corresponds
1272 to Scheme's (list->vector ...).
1273 (gh_vector_to_list): added this function as a macro. Corresponds
1274 to Scheme's (vector->list ...).
1276 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1277 gh_vector_ref, so that it resembles the Scheme routines more.
1278 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1279 resembles the Scheme routines more.
1280 (gh_make_vector): this used to be (stupidly) called gh_vector().
1281 This is the right name, since it does the same thing as the Scheme
1282 (make-vector ...) procedure.
1284 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1286 * ports.h: #include "libguile/print.h"
1288 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
1289 Some indentation fixes.
1291 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1292 longer a user field; New field: class_flags.
1294 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1296 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1298 * gh_data.c (gh_bool2scm): new function which replaces
1299 gh_int2scmb(), which is now tagged as obsolete.
1301 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1303 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1304 macros should by convention not test for NIMPness.)
1305 (SCM_COERCE_OPORT): Adjust indentation.
1307 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1308 SCM_NIMP test before SCM_PRINT_STATE_P.
1310 * struct.c, struct.h, gc.c: Renamed:
1311 scm_struct_i_layout --> scm_vtable_index_layout
1312 scm_struct_i_vcell --> scm_vtable_index_vcell
1313 scm_struct_i_vtable --> scm_vtable_index_vtable
1314 scm_struct_i_printer --> scm_vtable_index_printer
1315 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1317 * struct.c (scm_print_struct): Use new printer slot; Default
1318 printing: Also output hex code of vtable so that type identity
1319 will be indicated as well.
1320 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1321 Removed struct_printer_var; Removed struct-vtable-offset;
1322 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1323 vtable-offset-user): New constants.
1325 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1326 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1327 If this slot contains a procedure, use that to print structures of
1328 the type represented by this vtable.
1330 * print.c (scm_iprin1): Don't print arguments of macro
1331 transformers. (They are always: exp env.); Bugfix: Unmemoize
1332 transformer source with correct environment.
1334 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1336 Streamlining of call-with-dynamic-root:
1338 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1339 there is now only one catch.
1340 (cwdr_outer_body): Removed.
1341 (cwdr_handler): New function.
1342 (scm_internal_cwdr): New function to perform the function of cwdr
1343 but take args that are more useful to C code. Also, the handler
1344 is now invoked *outside* of the new dynamic root, like the docs
1345 say. We no longer have to catch absolutely all errors, the caller
1346 is responsible for using a handler that does not throw, if he
1348 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1349 * root.h (scm_internal_cwdr): New prototype.
1351 Even more but risky streamlining:
1353 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1354 allocation of the jumpbuf of a root continuation. The changes
1355 below are controlled by it. They are now deactivated.
1356 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1357 the JMPBUF of the scm_rootcont to NULL before returning.
1359 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1360 when they are non-NULL.
1361 (scm_gc_mark): Likewise, mark only when non-NULL.
1363 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1364 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1366 * gc.c (scm_done_malloc): New function.
1367 gc.h (scm_done_malloc): New prototype.
1369 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1370 (struct scm_print_state) [revealed]: New field.
1371 (scm_print_state_vtable): Make visible to the outside world for
1372 type checking purposes.
1373 (scm_valid_oport_value_p): New prototype.
1375 * print.c (scm_valid_oport_value_p): New function to check whether
1376 a certain value is acceptable as a port argument.
1377 (scm_print_state_vtable): New variable.
1378 (scm_free_print_state): Set `revealed' field to false.
1379 (scm_iprin1): Call user supplied closure printer with
1380 scm_printer_apply. Print in the traditional way when there isn't
1381 one or when it returns #f.
1382 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1383 Accept a port/print-state pair in addition to just a port.
1384 (scm_prin1): Don't return the print_state to the pool when it has
1386 (scm_printer_apply): Set `revealed' field of print_state to true.
1387 (scm_init_print): Set scm_print_state_vtable.
1388 (print_state_fluid, print_state_fluid_num): Removed.
1390 * throw.h (scm_handle_by_proc_catching_all): New prototype
1391 throw.c (scm_handle_by_proc_catching_all): New function
1393 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1395 * Makefile.in: Regenerated with automake 1.2c.
1397 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1399 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1400 was looping endlessly.
1402 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1404 * strports.c (scm_eval_string): Don't close the port.
1406 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1407 former returns a nice normal integer. (Thanks to Daniel
1410 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1412 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1413 makefile variable as a build parameter called LIBS. The
1414 build-guile program will use this, for the time being.
1415 * Makefile.in: Regenerated.
1417 Thanks to Shiro Kawai:
1418 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1419 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1422 * Makefile.in: Regenerated with automake 1.2a.
1424 * script.c (scm_compile_shell_switches): If we hit the -c or --
1425 arguments, don't set the car of (command-line) to scm_usage_name,
1426 the prettified name of the guile executable; give it the full
1427 path, the way shells usually handle $0.
1429 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1431 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1432 Scheme-level name `array-map' and renamed `serial-array-map' to
1433 `serial-array-map!'.
1435 * backtrace.c: Introduced exception handlers which now enclose
1436 `display-error' and `display-backtrace' so that error reporting
1437 won't get into infinite loops if an error occurs during displaying
1438 of the error. This can very easily happen with user supplied
1439 print call-back routines.
1441 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1443 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1444 the names `serial-array-map' and `array-map' should be removed.)
1446 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1448 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1449 Added #include "objects.h"
1451 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1452 Add #include "feature.h".
1454 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1455 (modinclude_HEADERS): Added objects.h.
1457 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1458 This test is needed at many places in the code and should be
1459 abstracted. (Motivated by the need of this test in libguiletk.)
1461 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1462 (scm_eval_string), load.c (scm_primitive_load,
1463 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1464 Use SCM_EOF_OBJECT_P.
1466 * eval.c (scm_init_eval): Add feature `delay'.
1468 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1470 * scmhob.h: Removed.
1472 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1474 * list.h (SCM_LISTn): New macros. Make list creation in C code
1475 prettier. The idea comes from STk.
1477 * sequences.h, sequences.c, append.h, append.c: Removed. These
1478 files implemented non-R4RS operations which would encourage
1479 non-portable programming style and less easy-to-read code.
1481 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1484 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1485 sequences.h, #include append.h.
1487 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1490 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1492 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1494 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1496 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1498 * eval.c: Added #include "objects.h"
1500 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1503 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1504 adjacent smob numbers.
1506 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1508 * procprop.h: Added declaration of scm_i_inner_name.
1510 * gsubr.c: New global symbol scm_i_inner_name.
1512 * debug.c (scm_procedure_name): Try procedure property
1513 `inner-name' if `name' fails.
1515 * print.c (scm_iprin1): Use scm_macro_name.
1517 * eval.c (scm_m_define): Give names to macros as well; Only the
1518 first top-level definition gives a procedure/macro a name.
1519 Otherwise confusing names can turn up in backtraces.
1520 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1521 `name'; Give names to macros as well.
1523 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1524 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1527 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1529 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1531 (prinmacro): Removed. The code has been moved/merged into print.c
1532 in order to decrease code redundancy. We want macros to print in
1533 a way equivalent to procedures, and it would be silly to duplicate
1534 the required code. (We don't want to maintain two places.)
1535 (macrosmob): Print field is now a NULL pointer.
1537 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1538 scm_macro_transformer): New prototypes.
1539 (scm_tc16_macro): Declared.
1541 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1542 are now printed in a way equivalent to procedures.

1553 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1555 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,

1557 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1558 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1559 SCM_BOOL_T. Any non-false value is true.
1561 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1563 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1564 scm_gensym): Added prototypes.

1580 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1582 * Makefile.in: Regenerated.
1584 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1586 * Makefile.in: Regenerated, so it uses "tar", not "gtar".

1590 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1592 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1594 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or

1599 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1600 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,

1606 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1608 * errno.h: prototype for scm_strerror.
1609 * error.c (scm_strerror): new procedure.
1611 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1613 * list.c (scm_list_append_x): Allow non-pair as last argument.
1614 This is consistent with the R4RS append and is probably the
1615 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1617 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1619 * stime.h: prototype for scm_times.
1620 * stime.c (scm_times): new procedure.

1637 third argument is now optional.
1639 * posix.c (scm_execl, scm_execlp): make the filename argument
1640 compulsory, since omitting it causes SEGV.
1641 (scm_sync): return unspecified instead of #f.
1642 (scm_execle): new procedure.
1643 (environ_list_to_c): new procedure.
1644 (scm_environ): use environ_list_to_c. disable interrupts.
1645 (scm_convert_exec_args): take pos and subr arguments and
1646 improve error checking.
1648 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1650 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1651 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1652 argument to SCM_ASSERT. Furthermore, the name of the function
1653 should be passed as first argument when signalling
1654 SCM_WNA. (Thanks to Thomas Morgan)
1656 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1657 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1658 dispatches on the number of actual args has a default case
1659 reporting an internal error. This is a vestige from a version
1660 that mallocated a SCM vector to hold the arguments. In the
1661 current version this check is too late: if it ever happens we will
1662 have already overstepped the bounds of the array.
1664 Also, the patch [...] adds a check for too many actual arguments."
1666 mdj: Removed check for "internal programming error".
1668 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1670 * gh_io.c (gh_write): New function.
1672 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1673 throw.c (scm_internal_stack_catch): New sibling to the other catch
1674 functions. Code moved from gh_eval.c.
1675 throw.h: Added header.
1676 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1677 scm_internal_stack_catch.

1683 Scheme name is now dup->fdes.
1684 (scm_dup_to_fdes): make the second argument optional and
1685 fold in the functionality of scm_primitive_dup.
1686 (scm_primitive_dup): deleted.
1688 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1690 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1691 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1692 ultrix are defined. Use setvbuf instead of setbuf.
1693 (scm_setvbuf): new procedure.

1709 (scm_init_print): Initialize them.
1710 (scm_iprin): If print_state_fluid carries a print_state, use that
1711 instead of creating a new one.

1713 definitions to help with calling printer functions written in
1715 * print.h (scm_printer_apply): New prototype.

1728 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1729 SCM_ASSERT: arg comes before pos.
1731 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1733 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1734 to a list of length zero correctly.
1736 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

1758 stream has been set.
1759 (scm_duplicate_port): deleted, there's now an implementation in

1812 data. (dynl_smob): Use it.
1813 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1814 the dynamic object data below the linking of the object to avoid
1815 memory leak when the linking code throws an error. Now the code
1816 leaks a whole dynamically linked library when must_malloc throws,
1817 but that should be much less likely.
1819 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1821 Changes to compile under gnu-win32, from Marcus Daniels:

1861 * read.c (recsexpr): Give this a dummy definition if
1862 DEBUG_EXTENSIONS isn't #defined.
1864 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
1866 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

1892 turn off REG_EXTENDED.
1893 (scm_init_regex_posix): New regexp/basic symbol.
1894 (REG_BASIC): #define this if it is not already present.

1941 (cwdr_outer_body): New function, to establish the user's handler,
1942 and pass control to cwdr_inner_body.

1954 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
1955 the feeling that real thread systems will not need this...
1957 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
1959 Try to detect when people are using one version of libguile and a

1973 * Makefile.am (libguile_la_LDFLAGS): Update library version to
1974 1:2. Helps avoid confusion between installed and uninstalled libs.
1976 * scmconfig.h.in: Regenerated. (Needed after June 3 change to

1999 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2001 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2002 argument plain char *.
2003 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2005 * tag.c (scm_tag): Remove unreachable statement.
2006 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2007 top of the word, it should be unsigned.
2009 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2010 is defined, to avoid warnings; it's only used in the
2011 conflict-checking code. Which might go away anyway.
2012 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2013 conditionals; put the label definition in an #if too, to stifle
2016 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2017 ChangeLog-threads in the distribution.
2018 * Makefile.in: Regenerated.
2020 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2022 * guile-snarf.in: Changed regexp to support CPPs that insert
2023 whitespace between lexical tokens (which munges the `%%%' snarf
2026 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2028 * load.c (scm_init_load_path): Append $(datadir)/guile to
2029 %load-path, so modules do not have to be installed in Guile's
2030 current version directory.
2032 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2034 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2035 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2036 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2037 call the sysdep functions with deferred ints.
2038 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2039 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2040 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2043 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2046 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2048 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2050 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2052 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2055 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2057 * eval.c (scm_lookupcar1): New procedure to cope with a race
2058 condition during lookup (when using threads).
2059 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2060 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2063 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2065 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2066 supplied. (Change from Tim Pierce.)
2068 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2070 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2071 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2072 default and not `()'. `#f' is the canonical non-value in Scheme,
2075 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2077 * struct.c (struct_printer): New variable that holds a handle on
2078 the Scheme variable *struct-printer*. This variable can be set by
2079 Scheme code to override the printing of structures.
2080 (scm_print_struct): If struct_printer is set, call it. If it is
2081 not set, or returns #f, print the structure in the old fashion.
2082 Include "eval.h" for scm_apply.
2084 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2086 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2087 scm_struct_i_n_words to get the number of fields, not
2088 -scm_struct_n_extra_words.
2090 On the route to fancier struct printing:
2091 * struct.c (scm_print_struct): New function to print a structure.
2092 Include "genio.h" to support it. This function doesn't do
2093 anything interesting right now, but I think it should be here
2095 * struct.h: Include "print.h" and add prototype for
2097 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2098 print structures ourself.
2100 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2102 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2103 before applying the handler in case it doesn't return.
2105 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2107 * scmsigs.h, async.h: updated.
2109 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2112 * posix.c (scm_uname): interpret only negative values as an error.
2113 Solaris normally returns a positive value.
2115 * script.c (scm_compile_shell_switches): if we are not going into
2116 an interactive repl, set scm_mask_ints to zero so that asyncs can
2119 * simpos.c (scm_system): don't ignore/unignore signals around
2122 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2125 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2126 done in boot-9.scm instead.
2128 * scmsigs.c, async.c: Major rewriting of signal handling code.
2129 (scm_sigaction): new procedure.
2130 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2132 (scm_raise): return unspecified, throw error on failure.
2134 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2136 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2137 feature, to help boot-9.scm decide whether to import the regex
2140 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2142 * eval.c: Include scmconfig.h at the beginning of the file so that
2143 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2146 * regex-posix.c: #include "_scm.h" before conditionally #including
2147 <regex.h>; the former defines HAVE_REGCOMP.
2149 * regex-posix.c: #include <regex.h> conditionally, so the file is
2150 CPP'able (for dependency scanning) even on systems that don't have
2153 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2155 Add new R4RS-compliant syntax for keywords.
2156 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2157 regardless of the setting of the `keywords' read option.
2158 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2159 can be re-read no matter what the setting of the `keywords' read
2162 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2164 Add support for POSIX regular expressions.
2166 * regex-posix.c, regex-posix.h: New files. (Some code
2167 is taken liberally from rx/rgx.c in the old Guile dist.)
2169 * init.c: Include regex-posix.h.
2170 (scm_boot_guile_1): Call scm_init_regex_posix.
2172 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2173 Add regex-posix.[ch] sources.
2174 * Makefile.in: Regenerated.
2176 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2177 to do this automatically? It didn't for me, bleh.)
2179 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2181 * fports.c (print_pipe_port): New function.
2182 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2183 latter doesn't even take the right arguments.
2185 * Makefile.am: Increment shared lib revision number. I think
2186 sometimes the uninstalled Guile finds the installed shared lib;
2187 Gord says doing this might help. As things turned out, I can't
2188 say whether it does.
2189 * Makefile.in: Regenerated.
2191 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2192 passing it as the closure argument to scm_boot_guile. (Bill
2195 * ports.c (print_void_port, putc_void_port, puts_void_port,
2196 write_void_port, flush_void_port, getc_void_port, close_void_port,
2197 noop0): Use ANSI prototypes instead of K&R declarations, so the
2198 initialization of void_port_ptob gets aggressively type-checked.
2199 Fix arguments of print_void_port and write_void_port. (Bill

2233 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2235 * script.c (scm_find_executable): Use prototype-style definition
2236 here; apparently it's not quite right to have const in a prototype
2237 and then use a K&R declaration. I wonder if stuff like this will
2238 go away if we compile with -Wrequire-prototypes, or whatever that
2239 is... (Bernard URBAN)
2241 * scmhob.h: New text from Bernard URBAN.
2243 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2245 * script.c: Don't #define const on hpux. Configure takes care of
2246 this. (Thanks to Larry Schwimmer.)
2248 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2249 decide whether to #include <unistd.h>, instead of listing a bunch
2250 of systems. Don't #include stdio twice. Removed dyked-out
2251 definition of scm_find_impl_file.
2253 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2255 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2256 library version info to 1:0.
2257 * Makefile.in: Regenerated.
2259 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

2263 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2264 throw.c: Update copyright years; these files have been worked on
2265 significantly in 1997, but only had copyright years for 1996.
2266 Also, change name of copyright holder on some from Mikael
2267 Djurfeldt to Free Software Foundation; he has signed papers
2268 assigning the changes to the FSF.
2270 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2271 reason not to give the user the option.
2273 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2274 Return #f on end-of-file when scanning table (i.e. when called
2275 with no arguments). Try to catch errors, when we can.
2276 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2278 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2279 external declarations. These are useful.
2281 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2283 * posix.c: don't include <sys/select.h> or define macros for
2284 select, since they were not used in this file.
2286 * filesys.c (scm_select): make the fifth parameter microseconds,
2287 not milliseconds. let the fourth parameter be either a real value
2288 or an integer or #f. The first, second and third arguments can
2289 now be vectors: the type of the corresponding return set will be
2291 (set_element, get_element): new static procedures.
2293 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2295 * strports.c (scm_eval_string): New function.
2296 (scm_eval_0str): Trivially re-implemented in terms of
2298 * strports.h (scm_eval_string): New extern decl.
2300 * net_db.c (h_errno): Add extern decl for this.
2302 * fports.c (local_pclose): New function.
2303 (scm_pipob): Use it in the initializer here.
2306 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2307 Use a meaningful error message when signalling an error. For
2308 this, scm_gethost must check h_errno rather than errno.
2310 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2312 * Makefile.in: Regenerated, using automake-1.1p.
2314 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2316 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2317 not SCM_UNSPECIFIED.
2319 * script.c (scm_compile_shell_switches): don't append (quit) if
2321 (scm_shell): call scm_exit_status and exit on the result of the
2324 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2326 Ensure that shared substrings are handled properly when passed to
2327 a system call or other foreign function. Many thanks to Tim
2329 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2330 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2331 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2332 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2334 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2335 (scm_display_error_message): use RO macros when strings may be RO.
2336 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2337 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,

2343 scm_strftime), vports.c (scm_make_soft_port): use
2344 SCM_COERCE_SUBSTR to make sure shared substrings are
2347 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2349 * error.c (scm_error): Add newline to error message.
2351 * init.c (scm_init_standard_ports): Doc fix.
2353 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2355 * dynl-shl.c: Completely replaced with new code from Bernard
2358 * script.c (scm_ice_9_already_loaded): New variable.
2359 (scm_compile_shell_switches): Use it.
2361 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2363 * filesys.c (scm_input_waiting_p): add missing third argument to
2366 * stime.c (scm_localtime): copy the result of localtime before
2367 calling gmtime in case they share a buffer.
2368 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2371 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2373 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2375 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2377 * Makefile.am (check-local): New target, which causes 'make check'
2378 to run gh_test_c and gh_test_repl, with some trivial input.
2379 * Makefile.in: Rgnrtd.
2381 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2383 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2386 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2388 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2389 sure how this was supposed to work.
2390 (scm_async_click): don't send SCM_TICK_SIGNAL.
2391 (scm_init_async): don't initialize %tick-thunk.
2393 * the following change doesn't affect the Scheme interface:
2394 gc-thunk is called at the end of garbage collection. however it's
2395 no longer implemented by pretending it's a signal.
2397 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2398 system async corresponding to scm_gc_thunk.
2399 * async.h: declare scm_gc_async.
2400 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2401 gc-thunk directly, instead of going through a signal handler.
2402 (scm_gc_async): new variable, points to the GC system-async.
2403 (scm_init_async): save the GC async as scm_gc_async instead
2404 of using system_signal_asyncs.
2405 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2407 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2409 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2410 Don't screw up if we're interrupted.
2411 * Makefile.in: Regeneradet.
2413 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2415 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2417 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2418 we're not using AM_INIT_GUILE_MODULE any more.
2419 * Makefile.in: Reneregated.
2421 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2423 Functions for finding variable bindings, grace à Tim Pierce.
2424 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2425 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2427 Get 'make dist' to work again.
2428 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2429 * Makefile.in: Regenerated, like a surry without a fringe on top.
2431 Changes for reduced Guile distribution: one configure script,
2433 * configure.in, configure: Removed.
2434 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2435 real configure script lives.
2436 * Makefile.in, scmconfig.h.in: Regenerated.
2438 * init.c: #include "script.h", to get prototype for script.c's
2441 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2443 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2444 scm_must_malloc, not raw malloc.
2446 * script.c (scm_compile_shell_switches): Dyke out debugging output
2449 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2451 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2453 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2454 system has them. Hope this is safe. Previously
2455 sys/timeb.h was included if HAVE_FTIME was defined or if
2456 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2457 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2459 * ioext.c (scm_setfileno): add missing third argument to
2460 scm_misc_error call.
2462 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2464 * eq.c (scm_equal_p): Correctly compare strings of different
2465 varieties. (Thanks to Tim Pierce.)
2467 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2469 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2470 #! block comment must occur on a line all by itself.
2472 Move most of the guts of shell command processing into libguile,
2473 so guile.c can be very small (and eventuallly auto-generated. (I
2474 mean, generated mechanically, not self-generated. Hmm.))
2475 * guile.c, script.c, script.h: New source files.
2476 * init.c (scm_boot_guile_1): Call scm_init_script.
2477 * libguile.h: #include "script.h".
2478 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2479 targets, for new executable.
2480 (libguile_la_SOURCES): Mention script.c.
2481 (modinclude_HEADERS): Add script.h.
2482 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2483 not dynamic linking is enabled. This is because we're generating
2484 executables now. Move CY_AC_WITH_THREADS call after those, so the
2485 values of cy_cv_threads_libs captures the libs chosen above.
2486 * Makefile.in, configure, aclocal.m4: Regenerated.
2488 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2489 We don't maintain this interface any more, and it just confuses
2492 * alloca.c: #include <scmconfig.h>, not <config.h>.
2493 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2494 it'll get included in disties.
2496 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2498 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2499 be distributed, because they confuse people.
2500 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2502 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>

2505 OpenBSD by default).
2506 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2507 * configure, scmconfig.h.in: Regenerated.
2509 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2511 * backtrace.c (scm_backtrace): Split message string across
2512 newlines properly. GCC is more tolerant of this than other
2515 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2517 Merge threads directory into libguile.
2518 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2519 threads.h: New source files.
2520 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
2521 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2523 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2524 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2525 coop-threads.c.cygnus, coop-threads.h.cygnus.
2526 * configure.in: If we're using threads, include threads.o in
2528 * _scm.h, libguile.h: threads.h lives in this directory now.
2529 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2530 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2531 currently used, but brought along for information's sake.
2532 * ChangeLog-threads: log from old 'threads' directory.
2533 * Makefile.in, configure: Rebuilt.
2535 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2537 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2540 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2542 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2544 Merge GH interface library into libguile.
2545 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2546 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2547 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2548 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2550 (EXTRA_libguile_la_SOURCES): ... here.
2551 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2552 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2553 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2554 New variables, describing how to build the gh test programs.
2555 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2556 build the test programs, and we probably should have been linking
2557 libguile.la against them all along, to support AIX shared libs.
2558 Add cflags for threads to CFLAGS; add libs for threads to new
2559 variable THREAD_LIBS, used in Makefile.am.
2560 * ChangeLog-gh: log from old `gh' subdirectory.
2561 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2563 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2565 * acconfig.h: Undo change of Apr 9; including the definition of
2566 PACKAGE in the guile headers conflicts with applications' own
2568 * scmconfig.h.in: Regenerated.
2570 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

2577 when PROC is receiving no arguments.
2579 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2581 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2582 have S_IFSOCK. This is the case under Ultrix.
2584 * posix.c (scm_status_exit_val, scm_status_exit_val,
2585 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2586 Ultrix versions of WIFSTOPPED, etc., which assume that their
2587 arguments are lvalues (hmm).
2589 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2591 * eval.c: Doc fixes.
2593 * throw.c: Doc fixes; rearranged.
2595 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2597 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2599 * acconfig.h: Added entry for PACKAGE.
2600 * scmconfig.h.in: Regenerated.
2602 Changes to work with automake-1.1n, which has better libtool support.
2603 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2604 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2606 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2608 * Makefile.in: Rebuild.
2610 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2612 * stime.c (scm_mktime): take an optional zone argument.
2613 (scm_localtime): check putenv return value.
2614 (scm_strftime, scm_strptime): moved from posix.c. move #include
2616 stime.h, posix.h: update prototypes.
2617 (bdtime2c, setzone, restorezone): new static procedures.
2618 (scm_mktime, scm_strftime): use them.
2619 (scm_strftime): don't call mktime before strftime. Use
2620 filltime for return value.
2621 (filltime): convert NULL zname to #f.
2622 (scm_strptime): return a count of characters consumed, not
2623 the remaining string.
2625 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2627 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2628 (scm_mktime): likewise.
2630 Uncomment localtime and mktime.
2632 * configure.in: add AC_STRUCT_TIMEZONE.
2634 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2636 * stime.c (scm_init_stime): don't define ticks/sec.
2637 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2638 return value problem and is still portable.)
2640 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2642 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2643 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2644 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2645 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2646 cpp_err_symbols.c): Corresponding changes.
2647 * Makefile.in: Regenerated.
2649 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2651 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2652 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2653 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2654 * putenv.c: new file, from sh-utils 1.12.
2656 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2657 since allocation isn't for Scheme objects.
2658 (scm_putenv): copy strings before placing in the environment.
2660 * stime.c (scm_current_time): throw an error if time returns -1,
2661 instead of returning #f.
2662 (scm_get_internal_real_time, scm_get_internal_real_time): use
2663 scm_long2num for return value instead of SCM_MAKINUM.
2665 * stime.h: prototypes updated.
2667 * stime.c (scm_time_in_msec): apparently unused, deleted.
2669 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2671 * configure.in: check for gettimeofday.
2673 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2674 which may be more usefully portable than a gettimeofday interface.
2676 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2678 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2680 * Makefile.in: Regenerated.
2682 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2684 * stime.c (filltime): recovered static procedure.
2685 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2688 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2689 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2691 * posix.c (scm_mknod): split the mode argument into type and perms
2692 arguments, like the extra fields returned by stat.
2694 * fports.c (scm_pipob): set the close, free and print procedures.
2695 (scm_close_pipe): new procedure.
2697 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2698 define them in boot-9.scm
2700 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2702 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2703 wan't defined. Don't include fd.h.
2705 * Previously fd.h was regenerated whenever configure was run,
2706 forcing a couple of files to be recompiled.
2708 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2709 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2710 Check for _fileno as well as _file.
2712 * ioext.c: don't fd.h.
2713 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2716 * Change the stratigy for getting information about errno
2717 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2718 generating lists of symbols during the build process, which will
2719 not always work, include comprehensive lists in the distribution.
2720 To help keep the lists up to date, the "check_signals" and
2721 "check_errnos" make targets can be used.
2723 * configure.in: don't check for a command to extract errno codes.
2724 * Makefile.am: update file lists, remove errnos.list and errnos.c
2725 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2726 check_errnos targets.
2727 (CLEANFILES): remove errnos.c and errnos.list, add
2728 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2729 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2730 * errnos.default: deleted.
2731 * cpp_signal.c: new file.
2732 * cpp_errno.c: renamed from errnos_get.c.
2733 * cpp_err_symbols, cpp_sig_symbols: new files.
2734 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2735 * error.c (scm_init_error): #include cpp_err_symbols instead of
2737 * posix.c (scm_init_posix): don't intern signal symbols. #include
2740 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2742 * strop.c (scm_i_index): allow the lower bound to be equal to the
2743 length of the string, so a null string doesn't always give an error.
2745 * posix.h: new prototypes.
2746 * posix.c (scm_status_exit_val, scm_status_term_sig,
2747 scm_status_stop_sig): new functions, as in scsh. They break down
2748 process status values as returned by waitpid.
2750 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2752 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2753 configure doesn't know about it.
2755 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2757 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2759 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2760 which defines C variables with global linkage.
2762 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2764 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2767 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2769 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2770 has time to check why this doesn't work well with continuations.
2772 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2774 * Fix shell syntax error; some shells won't tolerate
2775 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2777 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2779 * posix.c (scm_uname): throw an error if uname fails instead
2782 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2784 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
2787 * async.c (scm_ints_disabled): definition moved from error.c.
2789 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2791 * acconfig.h: Removed PACKAGE.
2793 * scmconfig.h.in: Regenerated.
2795 * snarf.h: g++ says it's non-portable not to specify the first
2796 argument in a varargs declaration. I introduced the first
2797 argument by using preprocessor conditionals.
2799 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2801 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2802 (scm_freopen): use RO string macros for filename and modes.
2803 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
2805 * posix.c (scm_getgrgid): simplify conversion of name to C string.
2806 (scm_mknod): use RO string macros for path.
2808 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2809 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2811 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2812 use SCM_ROSTRINGP and SCM_ROCHARS.
2814 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2816 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2819 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
2820 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
2821 support for byte vectors.
2823 * print.c (scm_iprin1): Limit number of vector elements printed
2824 according to pstate->length.
2826 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2828 * backtrace.c (scm_display_error_message): don't segv if message
2831 * error.h: prototype for scm_error_scm.
2833 * error.c (scm_error_scm): new procedure, reimplements scm-error
2834 in C and uses scm_error.
2836 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2838 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2839 pointer to the Scheme variable read-hash-procedures and intern it
2840 in scm_init_read. Modify scm_read_hash_extend and
2841 scm_get_hash_procedure to use the pointer.
2843 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2845 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2846 (SCM_KEYWORD_STYLE): defined.
2848 * read.c (scm_read_opts): add a keywords option. This isn't a
2849 boolean option, in case someone wants to add support for DSSSL
2851 Setup scm_keyword_prefix symbol.
2852 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2854 I've left keyword support disabled by default, since it doesn't
2855 seem to break the module system and it gives R4RS standard behaviour.
2856 It can be reactivated with (read-set! keywords 'prefix).
2858 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2860 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2861 before constructing arbiter.
2863 * eval.c (scm_m_define): Bugfix: Check that the object is a
2864 closure before setting the procedure property!
2866 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2868 * ports.c: Removed `ungetc-char-ready?'.
2870 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2872 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2873 (idea from Mikael: make it a pair so scm_permanent object only
2875 (scm_read_hash_extend): don't call scm_permanent_object.
2876 (ideas from Mikael): if chr is already in the list, replace its
2877 procedure instead of appending it again. If proc is #f, remove
2879 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2881 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
2883 * gdbint.c (gdb_read): update scm_lreadr usage.
2885 * load.h: update prototypes.
2887 * load.c (scm_primitive_load, scm_read_and_eval_x,
2888 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
2890 * read.h: add prototype for scm_read_hash_extend. Change args for
2893 * read.c (scm_read_hash_procedures): new variable.
2894 (scm_read_hash_extend): new procedure.
2895 (scm_get_hash_procedure): new procedure.
2896 (scm_lreadr): use scm_get_hash_procedure instead of an argument
2897 for extended # processing.
2898 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
2899 scm_read_token): remove case_i, sharp arguments. Change callers.
2901 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
2903 * read.h (SCM_N_READ_OPTIONS): increase to 3.
2904 (SCM_CASE_INSENSITIVE_P): define.
2906 * read.c: add case-insensitive option to scm_read_opts.
2907 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
2908 to determine whether to convert symbol case.
2909 (default_case_i): definition removed.
2910 * read.c (scm_read_token): if case_i, downcase ic before doing
2913 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2915 * configure.in: Added configuration option `guile-debug'.
2916 Configure with --enable-guile-debug if you want a bunch of extra
2917 functions used for debugging when developing Guile.
2919 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
2921 * procs.c (make-cclo): New undocumented debugging procedure: Make
2922 compiled closure with internal procedure PROC and length LENGTH.
2923 Only compiled if GUILE_DEBUG is defined.
2925 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
2927 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
2929 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
2931 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
2932 with 3 or more args internally to the evaluator.
2934 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2936 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
2937 with 3 or more args internally to the evaluator. This is mainly
2938 because we don't want to pass entry and exit points of the
2939 debug support twice, but it also seems to increase the speed of
2940 the evaluator for such calls (e. g. (+ 1 2 3)).
2942 * backtrace.c (scm_display_application): New procedure:
2943 display-application; Set fancy printing parameters individually
2944 for different types of display (backtrace, error, application).
2945 (These should of course be customizable!)
2947 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
2948 clear the CHECK-flags.
2950 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2952 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
2954 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2956 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
2957 from pairs with a GLOC in the car.
2959 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
2960 otherwise `symbol-hash' will behave badly.
2961 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
2962 we get segmentation fault!
2964 * symbols.c: Added #include "weaks.h". New functions:
2965 `builtin-bindings' and `builtin-weak-bindings'. (These will be
2966 moved to an extraneous library when we split libguile.)
2968 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2970 * filesys.c (scm_stat): stat now takes fport arguments too as
2971 documented in the manual.
2973 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2975 * debug.c (scm_single_step): Bugfix: Call continuation with
2976 scm_call_continuation instead of throwing to it.
2978 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2980 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
2981 argument wasn't declared to be optional.
2983 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2985 * stime.c (scm_init_stime): Add feature "current-time".
2987 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2989 * throw.h: prototype for scm_exit_status.
2990 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
2991 args to derive an exit status. Allows (quit) to work from a
2993 (scm_exit_status): new function.
2996 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2998 * eval.c (scm_deval): Removed some old code.
2999 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3001 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3004 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3007 * procs.c: Introduce the existent C function scm_thunk_p at the
3008 Scheme level as well.
3010 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3012 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3013 used from C to easily lookup the value of a symbol in the current
3016 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3018 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3019 scm_init_unif in this file. This will also fix a previous problem
3022 * configure.in: Added AM_MAINTAINER_MODE
3024 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3026 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3029 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3031 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3032 source files that are not always included in libguile but should
3033 have their dependencies calculated by automake. This variable is
3034 recognized by automake, no further magic is needed.
3035 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3036 to deal exclusively with *.lo files, as it seems. The *.o files
3037 are built automatically when the corresponding *.lo file gets
3040 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3042 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3045 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3047 * unif.c (scm_array_set_x): minor change to argument error checking.
3049 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3051 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3052 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3053 They should only be included in the library at configure.in's
3055 (libguile_la_LDADD): Include the appropriate .lo files here.
3056 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3057 so we know when to build them (and their .lo bretheren).
3058 * configure.in (LIBLOBJS): New substituted variable. We let
3059 configure decide which .o files to include in LIBOBJS, and then
3060 put the corresponding list of .lo files in LIBLOBJS. The latter
3061 is what we pass to libtool.
3062 * Makefile.in, configure: regenerated.
3064 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3066 * symbols.c (scm_sysintern0): New function. Contains the core of
3067 old scm_sysintern but doesn't take a second value argument.
3068 (scm_sysintern): Now uses scm_sysintern0.
3069 (scm_sysintern_no_module_lookup): Renamed to
3070 scm_sysintern0_no_module_lookup and doesn't take a second value
3071 argument any longer.
3073 * symbols.h (scm_sysintern0: Added declaration.
3075 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3076 scm_sysintern when interning option keys. Otherwise we risk
3077 destroying the values of already interned variables.
3079 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3080 scheme-level boolean (use SCM_NFALSEP).
3082 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3084 (scm_backtrace): New function. (C version of old function from
3085 boot-9.scm) Motivation: Make it possible to display backtraces
3086 without depending on boot-9.scm. (I'm uncertain if this
3087 motivation is good enough...)
3089 * root.h (scm_root_state): Add member the_last_stack_var.
3090 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3092 * root.c (mark_root): Mark scm_the_last_stack_var.
3094 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3097 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3099 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3100 1. mark_lazy_catch didn't mark the smob.
3101 2. Both functions above have standard variants:
3102 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3103 free_lazy_catch --> scm_free0.
3105 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3107 * throw.c (scm_internal_lazy_catch): New function.
3108 (scm_lazy_catch): Rewritten to use it.
3109 (scm_ithrow): Handle the new lazy catch representation.
3110 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3111 that doesn't have a jmpbuf is a lazy catch clause.
3112 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3113 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3114 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3116 (scm_init_throw): Register the new lazy-catch smob type.
3117 * throw.h (scm_internal_lazy_catch): decl for new function.
3119 * throw.c (scm_internal_catch): Doc fixes.
3121 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3122 configure.in. Including this might cause problems if applications
3123 that link against libguile include their own copies of alloca, but
3124 if they're using autoconf, they should be adding libguile to LIBS
3125 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3126 the copy in libguile, and things will be okay. (I think.)
3128 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3130 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3132 strop.h: move prototypes too.
3134 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3136 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3139 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3140 etc. I deleted them from filesys.c long ago, but didn't
3141 notice they were here too (although ineffective since
3142 sys/stat.h wasn't included).
3144 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3146 * eval.c: Don't define alloca in GCC case. gcc will automatically
3147 use __builtin_alloca if appropriate.
3149 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3151 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3152 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3153 that values of automatic variables are preserved. See comments
3154 for safe_setjmp for details.
3156 Change from Thomas Morgan:
3157 * variable.c: Include eq.h.
3158 (var_equal): New function.
3159 (variable_smob): Use var_equal as the discriminator for variables.
3161 * throw.c (s_throw): Remove extraneous declaration.
3163 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3164 * eval.c: Add necessary CPP cruft to support that.
3165 * configure, Makefile.in, scmconfig.h.in: regenerated.
3167 Change from Thomas Morgan:
3168 * procprop.c (scm_procedure_properties): Convert the Scheme
3169 boolean returned by scm_procedure_p into a C boolean before using
3170 it as a condition for SCM_ASSERT.
3171 (scm_procedure_property): Likewise.
3173 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3174 indications of Unixness.
3177 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3179 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3181 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3183 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3184 "unknown # object" error messages.
3186 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3187 (scm_i_index) and declare it static. Add a 'direction' argument
3188 to indicate what way the search should go.
3189 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3191 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3192 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3194 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3196 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3198 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3199 to avoid clash with various scsh forks.
3201 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3203 The following two changes (ramap.c, throw.c) are motivated by the
3204 apparent unportability of forward declarations of static arrays of
3205 the form `static foo bar[];'.
3207 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3208 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3210 * throw.c (scm_throw): Moved above scm_ithrow.
3212 * options.h: Removed the extern declarations of scm_yes_sym and
3213 scm_no_sym since these are static.
3215 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3217 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3219 * Makefile.am: remove AWK=@AWK@.
3220 Add a rule for generating errnos.list.
3221 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3223 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3224 don't extract errnos, just set a variable (avoids the
3225 need to recompile error.c just because configure is run.)
3227 * unif.h: update prototypes.
3228 * unif.c (scm_uniform_array_read,write): change the offset and
3229 length arguments to start and end, for consistency.
3231 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3233 * ioext.h: update prototypes.
3234 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3235 scm_read_line_x, it's a more general procedure using an
3236 interface from scsh. read-line and read-line! are now defined
3238 Note that the new read-line trims the terminator
3239 by default, previously it was appended to the returned string. An
3240 optional argument specifies how to process the terminator (scsh
3241 compatible). For the old behaviour: (read-line port 'concat).
3242 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3243 returns a pair, but is converted to multiple values if the scsh
3246 socket.h: update prototypes.
3247 * socket.c (scm_recvfrom): for consistency with other procedures,
3248 take start and end as separate optional arguments.
3249 (scm_recv, scm_recvfrom): don't allow the second argument
3250 to be a size, only a buffer. Change the scheme names to
3251 recv! and recvfrom!. Don't return the buffer.
3253 * ioext.h, posix.h: move prototypes too.
3254 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3255 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3256 "read.h" and "unif.h".
3257 * ioext.c: include "chars.h"
3259 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3261 * dynl.c: The dynamic linking and module registration functions
3262 are now defined even when dynamic linking is not available for the
3263 host system. Some of their functionality can be done without
3264 dynamic linking; when it's really needed, they throw errors.
3266 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3268 * configure.in: Only define DYNAMIC_LINKING when one of the system
3269 dependent functions is detected.
3270 * dynl.c (scm_dynamic_func): New function to get the address of a
3271 function in a dynamic object.
3272 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3273 produced by scm_dynamic_func as the thing to call.
3275 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3277 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3278 (scm_register_module_xxx, scm_registered_modules,
3279 scm_clear_registered_modules): New functions.
3281 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3283 * symbols.c (scm_sysintern): Renamed to
3284 scm_sysintern_no_module_lookup.
3285 (scm_sysintern): New function to take the place of the old
3286 scm_sysintern. It uses the current toplevel lookup closure to give
3287 the symbol its value. This is a temporary hack to put packages
3288 like gtcltk into their own module.
3289 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3290 us whether `scm_top_level_lookup_closure_var' has been initialized
3292 * eval.c (scm_init_eval): Set it.
3294 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3296 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3297 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3299 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3301 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3302 scm_sys_dup): deleted: FD capability will be added to other
3304 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3305 scm_fd_free, fd_smob, scm_intern_fd.
3306 (scm_open): renamed from scm_sys_open. Return a port instead of
3307 an FD object. Make the mode argument optional.
3308 (scm_sys_create): deleted, it's just a special case of open.
3309 (scm_init_filesys): move interning of constants O_CREAT etc.,
3310 here (were previously using SCM_CONST_LONG macro).
3311 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3313 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3314 include "fports.h" and <stdio.h>
3315 (scm_stat, scm_select): don't support FD objects.
3317 * error.h: adjust scm_syserror_msg prototype.
3318 * error.c (scm_syserror_msg): take an extra argument for errno.
3319 Using the global value didn't always work, since it could be
3320 reset by procedure calls in the message or args arguments.
3322 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3323 I don't understand why the check was there (and what about the
3326 * strop.c (scm_string_copy): allow shared substrings to be copied.
3328 * unif.h: corresponding change to prototypes.
3329 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3330 recognize two new optional arguments: offset and length. Allow
3331 the port argument to be an integer (file descriptor, for scsh).
3332 Include <unistd.h> for "read" prototype.
3334 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3336 * socket.c: don't include filesys.h.
3338 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3340 * Makefile.am: add AWK=@AWK@ (?)
3342 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3344 Add a rule to generate errnos.c from errnos.
3345 * error.c (scm_init_error): include errnos.c.
3346 * errnos_cnvt.awk: new file, converts the list of errno codes to
3348 * errnos_get.c: new file.
3349 * errnos.default: new file, contains errnos to try if they can't
3350 be extracted from errno.h.
3351 * configure.in: if using GCC, try and extract errno codes from
3355 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3357 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3358 * Makefile.am: Made libguile into a libtool library.
3359 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3360 Set libtool_libs to indicate that libguile is a libtool library.
3361 See guile/ChangeLog for details.
3362 * .cvsignore: ignore "*.lo", the libtool library objects.
3364 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3366 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3367 use htons in getservbyport argument.
3369 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3371 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3372 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3375 * objprop.c (scm_object_property): No need to take the CDR of the
3376 value returned by scm_object_properties, since Aug 20 change.
3378 * configure.in: When checking for struct linger, #include
3379 <sys/types.h> as well as <sys/socket.h>. I've never known
3380 <sys/types.h> to cause any portability problems, and Solaris's
3381 <sys/socket.h> needs it.
3382 * configure: Rebuilt.
3384 I think the Sun compiler has chosen a perverse way to interpret
3385 ANSI declarations combined with K&R definitions. We'll
3386 appease it a little bit. But when it invades France, we fight.
3387 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3388 * print.h (scm_iprlist): Here too.
3389 * numbers.c (scm_divbigdig): Change definition to match
3390 declaration in numbers.h.
3391 * unif.c (scm_makflo): Change definition to match declaration in
3394 * init.c (scm_boot_guile): Don't return the value of
3395 scm_boot_guile_1. This function doesn't return a value;
3396 scm_boot_guile_1 doesn't return a value (or return at all).
3398 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3401 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3402 compile. I have a feeling this function is a bad idea anyway ---
3403 one should always test for features, not systems.
3405 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3406 semicolons. Only pure luck kept this from being noticed earlier.
3408 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3410 * socket.c (scm_recvfrom): Added missing semicolon.
3412 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3414 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3415 the buffer and start and end positions for scsh networking
3418 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3420 * configure.in: Revert previous change to this file; the problem
3421 is due to transient automake weirdness.
3422 * configure: Rebuilt.
3424 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3425 PLUGIN/guile.libs. configure generates the latter from the former.
3426 * Makefile.in: Rebuilt.
3428 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3429 need this if we install scripts, like guile-snarf.
3430 * configure: Rebuilt.
3432 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3434 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3436 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3438 * socket.c (scm_addr_vector): fix faulty scm_listify.
3440 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3442 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3443 style block comment is no longer considered an error.
3445 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3447 * PLUGIN/guile.libs.in: New file.
3448 * PLUGIN/guile.libs: Removed from repository.
3449 * configure.in: Create PLUGIN/guile.libs from
3450 PLUGIN/guile.libs.in. This is for including additonal libraries
3451 needed for dynamic linking.
3452 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3453 instead of PLUGIN/guile.libs.
3455 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3457 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3459 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3460 occurrences of the given element from the list, not just the
3461 first. This is how the Emacs Lisp functions behave, how the
3462 analogous Common Lisp functions behave, and (I believe) how the
3463 older Maclisp functions worked. I realize that this change may
3464 break code, but it seemed better to break it before the Guile
3467 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3468 Their prototypes were already present in gc.h, but they weren't
3470 (scm_init_storage): Initialize scm_protects.
3471 * root.c (scm_protects): New element of scm_sys_protects.
3473 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3475 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3477 * libguile.h: Added #include "libguile/net_db.h".
3479 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3480 30 change. That file is only meant for communication between the
3481 configuration process and load.c. If code linked against libguile
3482 wants to get at the paths mentioned in libpath.h, it can call
3483 functions declared in load.h.
3485 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3487 * libguile.h: Removed #include "libguile/fdsocket.h"
3489 * net_db.c: Added #include <sys/socket.h>.
3491 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3493 * filesys.c (scm_input_waiting_p): use select in preference to
3494 FIONREAD, since the latter doesn't detect EOF.
3495 Throw error if neither select nor FIONREAD available.
3497 * socket.c (scm_connect): take a port, not a fd object.
3498 (scm_fill_sockaddr): throw an error if fam is not recognised.
3499 (scm_bind): use scm_fill_sockaddr.
3500 (scm_listen): take a port, not a fd object.
3501 (scm_accept): take and return a port. return #f in the car if
3502 address can't be got
3503 (scm_sock_fd_to_port): new procedure.
3504 (scm_socket): use scm_sock_fd_to_port.
3505 (scm_addr_vector): throw error if unrecognised address type.
3506 take an extra argument with the calling procedure name.
3507 (scm_getsockname): take a port. return #f if address can't be got.
3508 (scm_getpeername): take a port. return #f if address can't be got.
3509 (scm_recvfrom): take a port. return #f for address component if can't
3511 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3512 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3514 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3516 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3517 use separate data pointers, to allow them to be designed
3518 independently and reused.
3519 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3520 Renamed from catch_body, catch_handler, and uncaught_throw; made
3522 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3524 (scm_catch): Use the above.
3525 (scm_throw): Don't bother printing a message for an uncaught
3526 throw; we establish a default handler in init.
3527 * throw.h (scm_internal_catch): Prototype updated.
3528 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3530 (struct scm_body_thunk_data): New structure, used as data
3531 argument to scm_body_thunk.
3532 * init.c (struct main_func_closure): New structure, packaging up
3533 the data to pass to the user's main function.
3534 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3535 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3536 scm_internal_catch to establish a catch-all handler, using
3537 scm_handle_by_message. This replaces the special-case code in
3539 (invoke_main_func): Body function for scm_internal_catch; invoke
3540 the user's main function, using the main_func_closure pointer to
3541 decide what to pass it.
3542 * root.c (struct cwdr_body_data): Remove handler_proc member.
3543 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3544 (cwdr_handler): Removed.
3546 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3548 * socket.h (SCM_P): update bind prototype.
3549 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3550 include "feature.h".
3551 (scm_socket): return a port, not a file descriptor object.
3552 include "fports.h" and <unistd.h>
3553 (scm_bind): take a port, not a file descriptor object.
3554 take an extra argument for address args.
3556 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3557 INADDR_NONE, INADDR_LOOPBACK.
3559 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3561 * init.c: include net_db.h and not fdsocket.h.
3562 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3564 * Makefile.am: corresponding changes.
3565 * socket.h: renamed from fdsocket.h, fix names.
3566 * net_db.h: renamed from socket.h, fix names.
3567 * socket.c: renamed from fdsocket.c.
3568 remove _sys from procedure names.
3569 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3570 add "socket" to features list.
3571 * net_db.c: renamed from socket.c.
3572 remove _sys from procedure names.
3573 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3574 add "net-db" to features list.
3575 include "net_db.h". don't include <sys/socket.h> or
3578 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3580 * tags.h (scm_tags): Removed comma at end of last enumerator.
3582 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3584 Don't use GCC extensions to allocate space for debugging frames.
3585 (Here he goes again! Why do we put up with this?!)
3586 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3587 an scm_debug_info structure, not an in-line array of them. Add
3588 'info' member, to say how many vect elements we've used, for eval
3590 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3591 a new variable debug_info_end to mark the end of vect, instead of
3592 the address of the 'info' pointer itself.
3593 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3594 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3595 (SCM_APPLY): Explicitly allocate space for debug.vect.
3596 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3597 * stacks.c: Adjusted for new debug frame structure.
3598 (RELOC_INFO, RELOC_FRAME): New macros.
3599 (stack_depth, read_frames): Use them, and new scm_debug_frame
3600 element 'info', instead of magically knowing that eval frames have
3601 an info pointer sitting after vect.
3602 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3604 (scm_init_stacks): Formatting tweaks.
3606 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3608 Give GCC more control flow information, so it can be sure that
3609 variables aren't used uninitialized.
3610 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3611 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3612 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3613 scm_misc_error): Tell GCC that these functions never return.
3614 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3615 out the field type, call abort if SCM_ASSERT returns, to placate
3617 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3618 scm_wta ever returns. We can't handle this case anyway, and this
3619 gives the optimizer more information.
3620 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3621 scm_wta ever returns.
3623 In some cases, the code is fine, but GCC isn't smart enough to
3624 figure that out; this usually happens when one variable is only
3625 initialized and used when a particular condition holds true, and
3626 we know that condition will never change within a given invocation
3627 of the function. In this case, we simply initialize the variables
3628 to placate the compiler, hopefully to a value which will cause a
3629 crash if it is ever actually used.
3630 * print.c (scm_iprin1): Initialize mw_pos.
3631 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3632 * throw.c (scm_ithrow): Initialize dynpair.
3633 * unif.c (scm_uniform_vector_ref): Initialize cra.
3634 * struct.c (init_struct): Initialize prot.
3635 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3637 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3638 if EXPR contains no expressions.
3640 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3642 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3643 cause an infinite loop (???). So much for the algebraic
3644 equivalency of variable-sized arrays and alloca...
3646 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3648 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3649 a SCM boolean, not a C boolean.
3651 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3653 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3654 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3655 rules for raising scm_mtrigger. Previously, unfortunate but not
3656 unlikely circumstances could result in almost constant invokation
3657 of the gc. Now, this situations should be less likely, but they
3658 are not prevented completely.
3660 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3662 * numbers.c (scm_fuck): Procedure removed; looks like old test
3664 * numbers.h: Prototype removed.
3666 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3668 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3669 array to a pointer, to match my Nov 21 change in eval.c.
3671 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3673 * libguile.h: Added #include "libguile/backtrace.h", #include
3674 "libguile/stacks.h".
3676 * strings.c (scm_string scm_make_string scm_string_ref
3677 scm_string_set_x scm_string_equal_p scm_string_append):
3678 Bugfix according to scm patch from Aubrey Jaffer:
3679 Corrected long-standing
3680 (not (eqv? (integer->char 128)
3681 (string-ref (make-string 1 (integer->char 128)) 0)))
3682 bug found by John Kozak <jk@noontide.demon.co.uk>.
3684 * strports.c, strports.h: Make scm_eval_0str return the value of
3685 the last expression evaluated (previously, it returned void).
3687 * strports.c, strports.h: New function: scm_read_0str. Does what
3690 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3692 * simpos.c (scm_getenv): return #f if string can't be found in the
3693 environment instead of throwing an exception, for compatibility
3694 with numerous other systems.
3696 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3698 * Makefile.am (.c.x): Use guile-snarf.
3699 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3701 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3703 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3705 * backtrace.c (scm_display_error_message): Made non-static, and
3706 renamed from display_error_message.
3707 * backtrace.h (scm_display_error_message): Added extern decl.
3708 * throw.c (uncaught_throw): Use it to display the error message.
3710 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3712 * inet_aton.c: Use #if 0, not #ifdef 0.
3714 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3716 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3717 to convert the returned value.
3718 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3719 the offset argument.
3721 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3723 Add new interface to catch/throw, usable from C as well as
3725 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3726 (scm_internal_catch): New function, replaces...
3727 (scm_catch_apply): Deleted.
3728 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3729 mechanism which is a bit more code, but can be used nicely from C
3730 and implement the Scheme semantics as well.
3731 (scm_internal_catch): This is the replacement; it's named after
3732 the analogous function in Emacs.
3733 (scm_catch): Reimplemented in terms of the above.
3734 (struct catch_body_data, catch_body, catch_handler): New
3735 functions, used by scm_catch.
3736 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3737 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3738 support for new cwdr.
3740 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3743 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3745 * acconfig.h: Added DYNAMIC_LINKING symbol.
3746 * configure.in: Add option and checks for dynamic linking.
3747 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3748 dynl.h: New files for dynamic linking support.
3749 * Makefile.am (libguile_a_SOURCES):
3751 (modinclude_HEADERS): Added "dynl.h".
3752 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3754 * init.c (scm_boot_guile_1): Call
3755 scm_init_dynamic_linking to initialize dynamic linking support.
3757 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3759 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3760 (as we Schemers say). It needs to be global, so that I can tweak
3761 it for the proper operation of unexec.
3762 (scm_boot_guile_1_live): New variable, see above.
3764 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3766 * guile-snarf.sh: Removed.
3767 * PLUGIN/guile.libs: Added dependency for -lm.
3768 * acinclude.m4: Renamed from aclocal.m4.
3769 * PLUGIN/greet: Removed.
3770 * Makefile.am, aclocal.m4: New files.
3771 * configure.in: Updated for Automake.
3773 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3775 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3776 and not top_level_lookup_thunk_var.
3778 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3780 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3782 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3784 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3785 Scheme function, instead of syntax. Single argument is now a
3788 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3790 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3791 scm_ra_divide): Properly terminate statements passed as arguments
3792 to IVDEP macros. (Thanks to Bernard Urban.)
3794 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3795 with non-constant sizes. (Thanks to Bernard Urban.)
3797 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3799 It's an "eval closure", not an "eval thunk." A thunk is a
3800 function of no arguments.
3801 * root.h (struct scm_root_state): Renamed
3802 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3803 (scm_top_level_lookup_closure_var): Renamed from
3804 scm_top_level_lookup_thunk_var.
3805 * root.c (mark_root): Uses changed.
3806 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3807 * init.c (scm_start_stack): Uses changed.
3808 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3809 Change scheme-visible name to *top-level-lookup-closure* from
3810 *top-level-lookup-thunk*.
3812 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3814 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3815 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3817 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3819 * gc.c (struct scm_heap_seg_data): Doc fixes.
3821 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3822 sweeping. Then, prepend each segment's free cells to its
3823 freelist, rather than wiping out the old value. (Thanks to Marius
3826 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3827 scm_check_freelist, scm_debug_newcell): New functions and
3828 variables, for debugging freelist problems.
3829 * pairs.h (SCM_NEWCELL): New debugging version added.
3830 * gc.h (scm_debug_newcell): Added extern declaration, used by
3831 debugging version of SCM_NEWCELL.
3833 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3835 On some systems <libc.h> conflicts with <unistd.h>, and should not
3836 be #included at all.
3837 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3838 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3839 * configure.in: Call it.
3840 * posix.c, filesys.c: Use its results to decide whether or not to
3842 * configure, scmconfig.h.in: Rebuilt with autoconf and
3845 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3847 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3848 pointer to the stdio stream before calling scm_setbuf0, so the
3849 latter will be able to retrieve it. I'm surprised this didn't
3850 segfault earlier. (Thanks to Christopher Lee.)
3852 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3854 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3857 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3859 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3860 number of stack narrowing specifier pairs. The first specifier in
3861 a pair controls inner border, the second the outer border. A
3862 number means cut that number of frames, a procedure object means
3863 cut until that object is found in operator position in a frame.
3865 * root.c (cwdr): Bugfix.
3867 * read.c: Recording of positions disabled by default.
3869 * procs.c (scm_closure_p): New function.
3871 * posix.c (scm_tmpnam): New function.
3873 * load.c: Added #include "throw.h".
3874 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3877 * load.c, load.h (scm_read_and_eval_x): New function.
3879 * eval.c: Renamed debug option "deval" to "debug".
3881 (scm_eval_x): `eval!' is no longer accessible from the scheme
3882 level. Motivation: We can't allow operations which introduce
3883 glocs into the scheme level. Guile's type system can't handle
3884 these as data. Use `eval' or `read-and-eval!' as replacement.
3886 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
3887 SCM_CONSP since this is a macro!; Set vframe.prev to
3888 scm_last_debug_frame instead of 0. In this way we can look
3889 "above" the virtual start stack frame if we wish.
3890 (scm_debug_hang): New function: Useful for debugging Guile in
3891 certain tricky situations. Will probably be removed later...
3893 * debug.h: Changed semantics of debug option "backtrace". This
3894 option now only indicates whether we want automatic backtrace at
3897 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3899 * ports.c: #include "filesys.h"
3900 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
3902 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
3903 Motivation: This is system specific code which is related to file
3904 I/O. It also may use select. Added code by Gary Houston to
3905 detect presence of character in stdio buffers.
3907 * libguile.h: #include "libguile/libpath.h"
3909 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
3910 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
3911 SCM_SITE_DIR; Install libpath.h among the other include files.
3913 * load.c, load.h (scm_sys_package_data_dir): New function.
3915 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3917 * stacks.h: Bugfix: Don't use tail-array length field as stack
3918 length field! This screwed GC.
3920 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3922 * _scm.h: Added #ifndef around definition of macros min and max.
3924 * __scm.h: Added hooks for threads to plugin to in ints protection
3925 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
3926 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
3927 the main code in these macros duplicated and spread over multiple
3928 files. Renamed SCM_THREADS_SWITCHING_CODE ->
3929 SCM_THREAD_SWITCHING_CODE.
3931 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
3933 * snarf.h: New file.
3934 * guile-snarf.sh: New file.
3935 * Makefile.in (inner_h_files): Added snarf.h
3936 (ancillary, install, uninstall, distclean): Added actions for
3938 (.c.x): Use guile-snarf.
3939 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
3940 (gen_c_files): Note that these depend on guile-snarf.
3941 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
3942 now in "snarf.h". Added #include "snarf.h" to get them.
3943 * libguile.h: Added #include "snarf.h".
3944 (Patches applied and tweaked by Jim Blandy.)
3946 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3948 * socket.c: Use K&R style declaration for 'close'; the GNU coding
3949 standards suggest against providing prototypes for system
3950 functions. Thanks to Greg Troxel.
3952 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3954 * strports.c (scm_eval_0str): New function.
3955 #include "read.h", to get prototype for scm_read.
3956 * Makefile.in (strports.o): Update dependencies.
3957 * strports.h: New prototype.
3959 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
3960 scheme name from "int?" to "integer?". It seems to do the job.
3961 * numbers.h: Rename prototype too.
3962 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
3965 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
3966 scm_num_eq_p): Rename these according to R4RS conventions: call
3967 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
3968 to making libguile R4RS compliant without ice-9...
3970 * load.c (scm_sys_search_load_path): Search for files under all
3971 extensions listed in the %load-extensions variable. If FILENAME
3972 is absolute, return it unchanged, without searching the load path.
3973 (scm_loc_load_extensions): New variable, pointing to
3974 %load-extensions' value cell.
3975 (scm_init_load): Initialize it, and the value it points to.
3976 (scm_primitive_load_path): Improve error reporting.
3978 * load.c (scm_loc_load_hook): New variable, pointing to value cell
3979 of new Scheme variable %load-hook.
3980 (scm_primitive_load): Apply %load-hook to filename.
3982 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
3984 * configure.in: add tests for figuring out whether buffered data
3985 is available in a FILE structure, which is needed by char-ready.
3987 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
3990 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
3991 exceptions using misc_error instead of syserror. It seems a bit
3992 odd to throw an exception if a string can't be found in the
3993 environment, but it's consistent with open-file, stat etc.
3994 (simpos.h): remove sys_ from getenv.
3996 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
3997 occurs, throw an error instead of returning errno. Return value
3999 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4001 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4003 * filesys.c (scm_stat2scm): derive file type and permissions from
4004 the stat mode and append them to the returned vector.
4005 There isn't much overhead in doing this and it avoids the need to
4006 work with S_IRUSR et al. in Scheme.
4007 Define symbols scm_sym_regular etc.
4008 (scm_init_filesys): don't intern S_IRUSR etc.
4010 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4011 and s_primitive_load_path.
4013 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4015 * error.h: don't declare error symbols. prototype for scm_misc_error.
4017 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4020 * error.c: use SCM_SYMBOL to set up error keys.
4021 scm_misc_error: new procedure.
4023 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4025 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4026 between `#!' and `!#' is ignored.
4027 (skip_scsh_block_comment): New function.
4029 * feature.c (scm_set_program_arguments): New argument, FIRST.
4030 * feature.h: Update prototype.
4031 * init.c (scm_boot_guile_1): Pass new argument to
4032 scm_set_program_arguments.
4034 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4036 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4037 (scm_boot_guile): Call scm_set_program_arguments here, later than
4038 the old initialization.
4040 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4041 initialization procedure.
4042 - Delete in, out, err arguments; there are other perfectly good
4043 ways to override these when desired.
4044 - Delete result argument; this function shouldn't ever return.
4045 - Rename init_func argument to main_func, for less confusion.
4046 - Delete boot_cmd argument; main_func is more general.
4047 -Add 'closure' argument, to help people pass data to main_func
4048 without resorting to global variables.
4049 - Abort if reentered; don't bother returning an error code.
4050 - Call scm_init_standard_ports to set up the default/current
4051 standard ports; no need to pass them to scm_start_stack.
4052 - Remove code to evaluate the boot_cmd, and start the repl; let
4053 the user do something like that in main_func if they want.
4054 - Remove code to package up a return value; main_func can do any
4056 - Call exit (0), instead of returning.
4057 (scm_start_stack): Don't initialize the I/O ports here; that's
4058 weird. Delete in, out, err arguments. Move guts to
4059 scm_init_standard_ports, scm_stdio_to_port.
4060 (scm_init_standard_ports): New function, to set up current and
4061 default standard ports.
4062 (scm_start_stack, scm_restart_stack): Make these static.
4063 * init.h (scm_boot_guile): Adjust declaration.
4064 (scm_start_stack, scm_restart_stack): Remove externally
4065 visible declarations for these.
4066 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4068 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4069 written out several times in scm_start_stack.
4070 * fports.h: New declaration for the above.
4072 * feature.c (scm_set_program_arguments): New function.
4073 * feature.h: New declaration for the above.
4075 * ports.c: Formatting tweak.
4077 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4079 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4080 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4081 for obtaining the address of a car or cdr field. Motivation:
4082 &SCM_CXR make assumptions about the internal structure of the
4085 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4086 Motivation: see SCM_CXRLOC.
4088 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4089 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4090 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4091 Motivation: Safer use. Some other macros are defined in terms of
4092 these operations. If these are defined using the SCM_SETCXR
4093 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4094 to inefficiency and an <e1> with side-effects could potentially
4095 break. Also, these particular operations are heavily utilized in
4096 the garbage collector. In unoptimized code there will be a
4099 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4100 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4101 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4102 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4103 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4104 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4105 vports.c: Cleaned up use of pairs: Don't make any special
4106 assumptions about the internal structure of selectors and
4107 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4108 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4109 (Among other things, this change makes it easier to build Guile
4110 with certain compilers which have problems with casted lvalues.)
4112 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4114 * stacks.c: Improve selection of relevant stack frames when making
4115 a stack object. Introduce one level of indirection in the stack
4116 object to make it possible to "narrow" to a certain region of the
4117 stack. This facilitates making use of more clever algorithms (not
4118 implemented) for selecting relevant frames and gives a cleaner
4119 design since selection of frames can be done independently of
4120 extraction of frames from the real stack.
4121 (scm_stack_id): Also take #t as argument which means look at
4124 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4125 Turn n_tail into an integer directly representing current number
4126 of frames in stack. Add field tail.
4128 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4130 * debug.c (scm_make_memoized): Made it available at scheme level.
4131 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4132 SCM_NIMP before applying heavier predicates in argument checking.
4133 (scm_local_eval): Also take memoized object as argument.
4135 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4136 aren't created with zero length, but should such a strange
4137 creature suddenly turn up...
4139 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4141 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4142 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4144 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4146 * variable.c (scm_make_variable): Make the name hint optional, as
4148 (anonymous_variable_sym): Renamed from variable_sym. All uses
4151 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4152 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4153 of scm_primitive_load_path was also changed to
4154 "primitive-load-path", from "%try-load-path". Callers changed.
4155 We'd like to respect the convention that a function named
4156 "try-mumble" should behave just like the function called "mumble",
4157 but return #f instead of signalling some error.
4158 * load.h: Rename prototypes.
4160 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4162 * print.c (make_print_state, grow_print_state), print.h: Modified
4163 the print state representation: Don't use a tail array for
4164 recording of circular references. Resizing of the print state
4165 structure invalidates the print state pointer. To avoid passing
4166 around an indirect print state reference to all printing
4167 functions, we instead let the print state reference a resizable
4170 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4172 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4173 Don't crash when passed an improper list terminated by a
4174 non-immediate value.
4176 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4178 Allocate data for structures on an eight-byte boundary, as
4179 required by the tagging system.
4180 * struct.c (alloc_struct): New function.
4181 (scm_make_struct, scm_make_vtable_vtable): Call it.
4182 * struct.h (scm_struct_n_extra_words): Bump to 3.
4183 (scm_struct_i_ptr): New "field".
4184 * gc.c (scm_gc_sweep): When we need to free the data, use the
4185 information stored by alloc_struct to find the beginning of the
4186 block allocated to the structure, so we can free it.
4188 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4190 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4193 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4194 (scm_debug_info): New member: id.
4196 * stacks.c: Stacks are now represented as structs; Stacks have an
4197 id given to them by `start-stack'.
4198 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4200 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4201 Changed stack representation.
4203 * debug.c (scm_procedure_name): Try procedure property `name' for
4204 compiled closures aswell.
4206 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4208 * eval.c: scm_i_name moved to gsubr.c
4209 (scm_m_define): Record names of all kinds of procedure
4210 objects. (Earlier, only closures were recorded.)
4212 * procprop.h: Added declaration of scm_i_name.
4214 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4215 (scm_make_gsubr): Record names of compiled closures.
4217 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4219 * debug.c, debug.h: Removed obsolete code.
4221 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4222 stacks.c: Renamed regs --> scm_contregs.
4224 * print.c (scm_free_print_state): Cleanup print state before
4225 returning it to pool. It is better to do it here than in
4226 scm_prin1 since scm_prin1 is called often.
4228 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4229 s_set_source_property_x): Check that first argument is a pair or a
4232 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4233 scm_i_line, scm_i_column and scm_i_breakpoint global.
4235 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4236 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4239 * debug.h: Added debug object smob declaration and macro
4242 * configure.in: Build with backtrace.o and stacks.o if debug
4245 * Makefile.in: Added entries for new files: backtrace.c,
4246 backtrace.h, stacks.c and stacks.h.
4248 * symbols.c (scm_sym2ovcell): Fixed documentation.
4250 * _scm.h (min, max): Added.
4252 * async.c: Moved `min' macro to _scm.h.
4254 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4255 SCM_BACKTRACE_INDENT.
4257 * eval.c: Added new debug options `maxdepth' and `indent'.
4259 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4261 * print.h: Added selector SCM_PRINT_STATE.
4263 * print.c: New functions: scm_make_print_state,
4264 scm_free_print_state.
4266 * print.h: Added declarations for scm_make_print_state,
4267 scm_free_print_state.
4269 * debug.c (scm_m_start_stack): New acro.
4271 * debug.h: Small cleanup.
4273 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4276 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4301 More prototype-related changes from Marius Vollmer:
4302 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4303 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4304 * ports.h (ptobfuns): Added prototypes. This means some casting in
4306 * fports.c: Added casts for initializations, since the functions
4307 are defined to take FILE * as their stream argument, not SCM.
4308 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4309 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4310 to `char *str_data' to conform to prototype.
4312 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4314 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4316 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4318 * stime.c, stime.h: use SCM_P method.
4320 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4322 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4323 be given at least two arguments. Insist that lst's last element
4324 be a list, but don't make any requirements of its predecessors.
4326 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4328 * eval.c (scm_nconc2last): Revert last change; there seems to be
4329 other stuff going on here.
4331 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4333 * eval.c (scm_nconc2last): Make sure that each element of lst
4334 (which is a list of argument lists, except for the tail) is a
4335 proper list, i.e., finite and terminated by '().
4337 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4339 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4342 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4343 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4346 * vectors.c (scm_make_vector): Fill vectors with the undefined
4347 value, to help make Guile Scheme code more portable to other
4350 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4351 * symbols.h, tags.h: Doc fixes.
4353 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4355 * async.c (scm_take_signal): Doc fixes.
4357 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4359 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4360 want to subtract it from the modulus; we just want to leave it
4363 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4365 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4368 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4370 * throw.c (scm_catch_apply): Finished implementation of
4373 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4375 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4377 (scm_init_filesys): set "i/o-extensions" feature.
4380 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4382 * Makefile.in (root.o): Correct dependencies.
4384 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4386 * Makefile.in: Added dependency entry for root.o.
4388 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4389 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4391 * init.c (scm_start_stack): Set initial root continuation number
4394 * procs.c: New function: scm_thunk_p.
4396 * procs.h: Added declarations of scm_thunk_p.
4398 * root.c: Renamed `call-with-new-root' -->
4399 `call-with-dynamic-root'.
4400 (cwdr): Removed allocation of new root state. This should be done
4401 separately by use of scm_make_root.
4402 (scm_apply_with_dynamic_root): New function: Does what it
4403 sounds like. Needed when spawning threads.
4405 * root.h: Added member last_debug_frame to root state.
4406 Added #include "libguile/debug.h"
4408 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4409 arguments. The motivation is that code in root.c needs catch
4410 functionality, and we want to avoid code duplication.
4411 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4412 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4413 handlers that run without popping the stack into the dynwind
4416 * throw.h: Added prototypes for scm_catch_apply and
4419 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4421 * root.h (scm_root, scm_set_root): Decouple thread support details
4422 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4423 SCM_SET_THREAD_LOCAL_DATA.
4425 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4426 and tortoise scanning loop.
4428 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4430 * Makefile.in: Rebuild dependencies.
4432 * libguile.h: #include "libguile/print.h" before "smob.h", since
4433 the latter uses the print_state structure.
4435 * throw.c (scm_ithrow): Use the correct variable when checking to
4436 see if a given element of scm_dynwinds is a valid catch.
4438 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4439 structure, abort; don't just silently ignore the garbage.
4441 * _scm.h: #include "print.h" here, since it seems to be used just
4443 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4444 strports.c, unif.h: Don't #include "print.h".
4446 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4448 * feature.h (scm_loc_features): Removed external declaration.
4449 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4451 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4453 * feature.c (scm_init_feature): Added threads feature (needs to be
4454 initialized here, since features doesn't exist when
4455 scm_init_threads is called).
4457 * libguile.h: Added #include "libguile/../threads/threads.h".
4458 (This is a kludge to get thread support working. This should be
4461 * configure.in, acconfig.h: Added flags for thread support.
4463 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4466 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4467 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4470 * _scm.h: Added conditional #include "threads.h"
4472 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4473 SCM_THREADS_SWITCHING_CODE.
4475 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4476 allocate the basic dynamic root object.
4477 (scm_boot_guile): Added call to scm_init_root.
4479 * root.c, root.h: Added root smob.
4480 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4481 functions: Implements dynamic roots mostly according to spec in
4482 SCM manual. Main difference is that the second argument is a
4483 throw handler rather than an error "thunk".
4485 * root.h: Added declaration of scm_init_root.
4487 * root.c: Added #include "genio.h", #include "smob.h", #include
4488 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4490 (scm_init_root): Added #include "root.x".
4492 * throw.c: Added #include "stackchk.h"
4493 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4494 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4495 can be used in scm_call_with_new_root; Added reenabling of stack
4496 checking when catching a throw.
4498 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4500 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4502 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4503 element is not found, as per R4RS.
4505 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4507 * list.c: Doc fixes throughout.
4509 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4511 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4512 declare the char * to be const. Avoids a warning in rgx.c.
4514 * ports.h: spelling fix.
4516 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4519 * load.c (scm_sys_try_load_path): throw an error if file not found
4520 (like it says it in NEWS).
4522 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4524 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4525 PROPS slot to '(), not #f; it's an empty alist.
4527 * throw.h, throw.c: Use SCM_P instead of #if hair.
4529 Remove special support for uncaught throws; see throw.c for
4531 * throw.c (uncaught_throw): New function.
4532 (scm_ithrow): Call uncaught_throw if we don't find a throw
4533 target; don't mess with scm_bad_throw_vcell.
4534 (scm_bad_throw_vcell): Variable deleted.
4535 (scm_init_throw): Don't initialize it.
4537 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4540 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4542 * numbers.c (scm_istr2int): If the number is short (as most
4543 numbers are), just call scm_small_istr2int to deal with it.
4544 (scm_small_istr2int): New function, created by un-#ifdefing the
4545 non-bignum version of scm_istr2int and renaming it.
4547 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4549 * load.c (scm_sys_try_load): don't check whether value returned
4550 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4551 Change the Scheme name from %try-load to primitive-load.
4553 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4554 Can avoid passing a message, allowing it to be derived in the
4555 error handler (e.g., if we want to throw to the key both from
4558 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4560 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4561 references now have a new appearance which is more compact and
4562 also gives a clue about what the target of the reference is.
4563 By setting parameters in the print state, more fancy printing can
4564 be achieved. This is used by the (not yet commited) backtrace
4567 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4569 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4572 * print.c: Added #include "struct.h". Removed function
4575 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4576 scm_iprin1. Removed prototype for scm_prlist.
4578 * arbiters.c (prinarb),
4579 async.c (print_async),
4580 debug.c (prindebugobj, prinmemoized),
4581 eval.c (prinprom, prinmacro),
4582 filesys.c (scm_fd_print, scm_dir_print),
4584 mallocs.c (prinmalloc),
4585 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4586 smob.h (scm_smobfuns),
4587 srcprop.c (prinsrcprops),
4589 unif.c, unif.h (scm_raprin1, rapr1),
4590 variable.c (prin_var): Changed argument `int writing' to
4591 `scm_print_state *pstate'.
4593 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4594 that it will be called before scm_init_print.
4596 * print.c (scm_prin1): Print states are now allocated when calling
4597 scm_prin1 and then passed around to all printing functions as an
4598 argument. A cache `print_state_pool' enables reuse of print
4600 (scm_make_print_state): New function.
4601 (scm_iprin1): Adaption to print states.
4602 (scm_iprlist): An initial "hare and tortoise" scan brings down
4603 time complexity to O (depth * N). (Better time complexity will be
4604 achieved when the printing code is completely rewritten.)
4606 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4608 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4609 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4610 it gets done whether or not the cache variable has a value.
4612 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4614 Distinguish #f and ().
4615 * __scm.h: #undef SICP.
4616 * pairs.h (SCM_EOL): Delete this definition, equating it with
4618 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4619 the value it used to have. Doc fixes, too.
4621 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4623 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4624 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4625 Lord's implementation of structs, allowing for tail arrays as
4626 described in the manual. Also fixed some bugs. (Both the interface
4627 and the implementation should be improved.)
4629 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4631 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4632 People who whish to see the source can do `(print-enable 'source)'.
4633 Removed #ifdef DEBUG_EXTENSIONS.
4635 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4637 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4638 integer (assuming for now accepting an integer is a good thing).
4640 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4641 %S will be used instead for write'ing arguments.
4643 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4644 asserts. fix a few other asserts.
4645 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4646 scm_uniform_vector_ref, scm_array_set_x,
4647 scm_dimensions_to_unform_array): change args in
4648 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4649 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4650 scm_substring_fill_x): likewise.
4651 gsubr.c (scm_gsubr_apply): likewise.
4652 eval.c (SCM_APPLY): likewise.
4654 * eval.c (4 places): replace scm_everr with lgh_error or
4657 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4658 scm_memory_error): new procedures.
4659 scm_everr: deleted. can use scm_wta, dropping first two args.
4660 scm_error: convert NULL subr to SCM_BOOL_F.
4662 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4665 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4668 * error.c, error.h: new error keys: scm_arg_type_key,
4669 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4671 scm_wta: reimplement using lgh_error instead of scm_everr.
4673 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4675 * gdbint.c: scm_lread now has one more argument.
4677 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4678 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4679 loading source from non-file ports, which, e. g., happens when
4680 using the Emacs interface).
4682 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4685 * read.c: Added code for recording of positions of source code
4686 expressions; New functions: recsexpr, scm_lreadrecparen;
4687 _scm_make_srcprops --> scm_make_srcprops
4688 (scm_flush_ws): Removed updating of positions counters. This work
4689 is already done by scm_gen_getc
4691 * read.h: Added prototype for scm_lreadrecparen
4693 * print.c: Added #include "alist.h"
4695 * eval.c: Added #include "hash.h"
4697 * eq.c: Added #include "ramap.h"

4703 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4704 --> scm_make_srcprops
4706 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4707 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4708 function calls in the definition of the whash access macros.
4710 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4712 * init.c (scm_boot_guile): Add level of indirection to
4713 scm_boot_guile_1() to ensure that stack base pointer is properly
4714 initialized. There was no guarantee that variable i was the
4715 highest/lowest variable on stack (i.e. the call frame of
4716 scm_boot_guile was not completely protected from gc).
4718 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4720 * ports.h (scm_port_table): put back file_name, it will be used to
4721 support debugging. Undo related changes in fports.c, ioext.c,
4724 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4726 * ports.h (scm_port_table): remove file_name member for now, it seems
4728 * fports.c (scm_open_file): don't set file_name in PTAB.
4729 (prinfport): don't use file_name in PTAB.
4730 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4731 * ports.c (scm_add_to_port_table): don't intialize file_name.
4732 (scm_port_file_name): remove for now.
4733 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4735 * fports.h (scm_mkfile): prototype deleted.
4736 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4738 * debug.c, unif.c: use scm_out_of_range instead of
4739 wta for range errors (ASSERT still needs work).
4741 * error.c, error.h (scm_out_of_range): new procedure.
4743 * error.c, error.h (scm_out_of_range_key): new key.
4745 * posix.c (scm_sync): #else was missing.
4747 * error.c, error.h: append _key to names scm_num_overflow and
4750 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4751 of consing an empty list.
4752 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4753 of macros, saves code and string space.
4754 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4755 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4756 lower case. Rename scm_syserror_m to scm_syserror_msg.
4757 error.h: prototypes for new procedures.
4759 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4761 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4763 * error.c, error.h: setup scm_num_overflow key.
4765 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4766 Remove definition of SCM_OVSCM_FLOW.
4768 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4770 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4771 explicit message and args.
4773 * error.c, error.h, __scm.h: change system_error_sym to
4776 * error.c (system_error_sym): remove leading %% from the Scheme name
4779 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4781 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4783 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4784 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4785 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4786 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4787 renamed. (These were introduced by unsupervised name
4790 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4792 * print.c: Added code for detection of circular references during
4793 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4794 a hook for printing of closures (accessible via print options).
4795 This leads to a split of calls to scm_iprin1 into two classes:
4796 elementary print operations (e. g. the code which prints a smob)
4797 still use scm_iprin1 while top level calls (like scm_display) use
4798 scm_prin1. scm_prin1 begins by clearing the data structure used
4799 to record reference information.
4801 * print.h: Added declarations of scm_prin1 and scm_prlist.
4803 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4805 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4807 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4809 * error.c (err_head): scm_iprin1 --> scm_prin1
4811 * debug.c: Adjusted header comment.
4815 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4817 * strerror.c: Doc fix.
4819 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4821 * gdbint.c (gdb_read): Now possible to run during GC.
4822 (unmark_port, remark_port): New functions.
4824 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4826 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4827 of allocating a new string object. Also, increase size by
4828 the factor 2 instead of 1.5.
4830 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4832 * __scm.h (SCM_P): Corrected to run under traditional C.
4834 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4837 * async.c: Calls to scm_sysintern corrected.
4839 * async.h (scm_async_clock): Redundant declaration removed.
4841 * continuations.c (scm_dynthrow): Redundant declaration removed.
4843 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4844 Definition typos corrected.
4846 * debug.h: Missing declarations of functions in debug.c added
4849 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4850 Missing declarations to functions in eval.c added.
4852 * filesys.c: Possibly uninitialized variable rv.
4854 * gc.h (scm_object_addr, scm_unhash_name): Missing
4855 declarations of functions defined in gc.c added.
4857 * genio.c: Possible typos str_data -> wstr_data. ???
4859 * genio.c: Possibly unintended shadowing of local variable
4860 `int c' (gotos out of scope of inner `c'). ???
4862 * init.c: Uninitialized `SCM last' may be used.
4864 * ioext.h: (scm_sys_isatty_p): Typo.
4866 * list.h (scm_list_head): Missing prototype for function in
4869 * numbers.c (scm_two_doubles): Changed from extern to static
4870 (is used only within numbers.c).
4872 * numbers.h: Repeated declarations removed.
4874 * ports.h (scm_close_all_ports_except): Declaration for the
4875 function defined in ports.c added.
4877 * posix.h: Missing declarations added.
4879 * procs.h (scm_make_subr_opt): Missing declaration added.
4881 * socket.h (scm_sys_gethost): Missing declaration added.
4883 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4885 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
4886 Missing declarations added.
4888 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
4890 * struct.c: Uninitialized variable `SCM answer' may be used.
4892 * unif.c (l2ra): Declaration prototype.
4894 * unif.c (scm_array_equal_p): Dummy definition removed (it is
4895 defined in ramap.c).
4897 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
4898 Redundant declarations removed (they are in ramap.h).
4900 * variable.h (scm_make_udvariable,
4901 scm_make_undefined_variable): Declaration corrected to
4902 correspond variable.c.
4904 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
4905 Missing declarations added.
4907 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
4909 * Makefile.in (distclean): Don't forget to delete fd.h.
4911 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4913 * fd.h.in, tags.h: Trivial cleanups.
4915 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
4916 marksweep.h just declared functions from gc.c.
4917 * gc.h, libguile.h: Don't #include "marksweep.h".
4918 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4919 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
4920 dependencies updated.
4922 * libguile.h: Don't #include "files.h"; it's been deleted.
4924 * files.c (scm_sys_delete_file): Moved to filesys.c.
4925 File is now empty; deleted.
4927 * filesys.c: scm_sys_delete_file is now here. Remove
4928 #if's; they seem to rely on remnants of an old portability
4929 regimen. If the problems come up again, solve them properly,
4930 using autoconf. Specifically: Don't test M_SYSV, and #define
4931 remove to be unlink if it's #defined; don't use remove just
4932 because HAVE_STDC_HEADERS is #defined.
4933 * filesys.h: Add declarations for scm_sys_delete_file.
4934 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4935 files.o, files.h, files.c, and files.x.
4936 * init.c: Don't #include "files.h", and don't call scm_init_files.
4938 Use SCM_P instead of PROTO; the latter intrudes on the user's
4940 * params.h: Deleted; definition of SCM_P moved to...
4941 * __scm.h: ... here, where it replaces PROTO macro.
4942 * libguile.h, smob.h: Don't #include "params.h".
4943 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
4944 smob.h: Fix prototypes accordingly.
4945 * Makefile.in: Update dependencies.
4946 (inner_h_files): Remove params.h.
4948 * gc.c: #include "gc.h"; every module should include its header,
4949 to let the compiler cross-check the declarations against the
4952 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
4953 simpos.h: #include "libguile/__scm.h".
4955 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
4957 * init.c: Don't forget to #include smob.h and init.h.
4958 * Makefile.in: Dependencies updated.
4960 * smob.h: Use PROTO instead of #if __STDC__.
4962 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
4964 * __scm.h: Doc fixes.
4966 * __scm.h, libguile.h: Use "quotes" in the #includes, not
4967 <angles>; this allows `make depends' to work properly.
4969 * libguile.h: #include smob.h and pairs.h before the others; they
4970 define typedefs used by other headers.
4972 C files should #include only the header files they need, not
4973 libguile.h (which #includes all the header files); the pointless
4974 recompilation was wasting my time.
4975 * Makefile.in (all .o dependency lists): Regenerated.
4976 * libguile.h: Don't try to get a definition for size_t here...
4977 * __scm.h: Do it here.
4978 * _scm.h: Since this is the internal libguile header, put things
4979 here that all (or a majority) of the libguile files will want.
4980 Don't #include <libguile.h> here; that generates dependencies on
4981 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
4982 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
4983 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5080 * weaks.c: Get "weaks.h".
5082 * stackchk.h: #include "libguile/debug.h",
5084 * print.h, read.h: #include "options.h", since everyone who uses
5085 either of these files will need that.
5087 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5088 anyone who uses this file will need them to define the smob
5089 printing functions. Also, get markers.h, since people will need
5090 to #define the mark functions.
5092 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5093 * ports.h: ... to here.
5095 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5096 don't rely on archaic C default type rules.
5098 * fports.h: #include "libguile/ports.h", since you need that in
5099 order to parse this.
5101 * genio.h: #include "libguile/print.h", because you need that to
5102 parse this; don't bother #including "ports.h", since print.h gets
5105 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5107 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5108 this; it's now a reference to an element of *scm_root.
5110 * debug.h: Don't #include "options.h"; the compiler won't be able
5111 to find that once the headers are installed; instead, #include
5112 "libguile/options.h".
5113 * gc.h: Same, with marksweep.h.
5114 * mbstrings.h: Same, with symbols.h.
5115 * scmhob.h: Same, with _scm.h.
5116 * smob.h: Same, with params.h.
5118 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5119 C files; there's no need for this, and it forces recompilations
5122 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5124 * error.c (scm_error): declare scm_error_callback.
5126 * error.h: prototype for scm_error_callback.
5128 * __scm.h: define lgh_error.
5129 (SCM_SYSERROR): redefine using lgh_error.
5131 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5133 * error.c (scm_error): new procedure.
5135 * error.h: prototype for scm_error.
5137 * Makefile.in (install): install scmconfig.h from the current
5138 directory, not $(srcdir).
5140 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5142 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5143 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5144 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5145 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,

5149 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5150 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5151 vports.h, weaks.h: #include "libguile/__scm.h", not
5152 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5153 dependencies are within libguile properly.
5155 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5157 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5158 when scmconfig.h doesn't exist.
5160 * load.c (scm_sys_try_load): Correct spelling.
5162 * feature.c (scm_loc_features): Make this static.
5164 * Makefile.in (libpath.h): Omit trailing slash from path. We
5165 shouldn't require it of users, so why put it here?
5167 Move code to initialize and search %load-path from ice-9 to C
5168 code, so we can use the load-path to find the ice-9 boot code;
5169 this makes it easier to run Guile without installing it. See
5170 corresponding changes in guile/Makefile.in.
5171 * feature.c: Move stuff concerned with the load path to load.c.
5172 (scm_compiled_library_path): Deleted.
5173 Don't #include libpath.h here.
5174 * feature.h: Don't mention scm_compiled_library_path.
5175 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5176 <sys/stat.h>, and <unistd.h> (if present).
5177 (R_OK): #define if the system hasn't deigned to.
5178 (scm_loc_load_path): New variable.
5179 (scm_init_load_path, scm_sys_search_load_path,
5180 scm_sys_try_load_path): New functions.
5181 (scm_init_load): Initialize scm_loc_load_path to point to the
5182 value cell of the Scheme %load-path variable.
5183 * load.h: Add declarations for scm_sys_search_load_path,
5184 scm_sys_try_load_path.
5185 * init.c: Call scm_init_load_path.
5186 * Makefile.in (feature.o, load.o): Dependencies updated.
5188 * load.c, load.h: Rewrite using PROTO macro.
5190 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5192 * gc.c (scm_cellp): New function: C predicate to determine if an
5193 SCM value can be regarded as a pointer to a cell on the heap.
5195 * gc.h: Added declaration of scm_cellp.
5197 * gdb_interface.h: New file: The GDB interface header from the GDB
5200 * gdbint.c: New file: GDB interface.
5202 * gdbint.h: New file: GDB interface.
5204 * libguile.h: Added #include <libguile/gdbint.h>.
5206 * init.c (scm_boot_guile): Added scm_init_gdbint.
5208 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5209 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5210 found if object files and source are kept separate).
5212 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5214 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5216 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5218 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5219 TK_SRC_DIR; they're not relevant any more.
5221 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5222 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5224 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5226 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5227 search path, so we can find the <libguile/MUMBLE.h> headers.
5229 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5231 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5232 implicit in the .c.o rule.
5233 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5236 Put the library path in a header file, instead of passing it on
5237 the command line in every compilation.
5238 * Makefile.in (libpath.h): New target.
5239 (feature.o): Depend on libpath.h.
5240 (clean): Delete libpath.h.
5241 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5242 * feature.c: ... #include "libpath.h" here.
5243 * .cvsignore: Ignore libpath.h.
5245 Don't install the unwashed masses of Guile header files in the
5246 main #include path; put most of them in a subdirectory called
5247 'libguile'. This avoids naming conflicts between Guile header
5248 files and system header files (of which there were a few).
5249 * Makefile.in (pkgincludedir): Deleted.
5250 (innerincludedir): New variable; this and $(includedir) are enough.
5251 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5252 (installed_h_files): Divide this up. Now this variable lists
5253 those header files which should go into $(includedir) (i.e. appear
5254 directly in the #include path), and ...
5255 (inner_h_files): ... this new variable says which files appear in
5256 a subdirectory, and are referred to as <libguile/mumble.h>.
5257 (h_files): List them both.
5258 (install): Create innerincludedir, not pkgincludedir. Put
5259 the installed_h_files and inner_h_files in their proper places.
5260 (uninstall): Corresponding changes.
5261 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5262 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5263 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5264 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5265 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5266 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5267 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5268 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5269 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5270 vports.h, weaks.h: Find __scm.h in its new location.
5271 * __scm.h: Find scmconfig.h and tags.h in their new locations
5272 (they're both "inner" files).

5276 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5278 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5280 * posix.c: Doc fixes.
5282 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5284 * socket.c: Don't include a prototype for inet_aton; just use a
5285 K&R style declaration, to avoid warnings but minimize the chance
5286 of conflicts with the system.
5288 On NextStep, <utime.h> doesn't define struct utime, unless we
5289 #define _POSIX_SOURCE before #including it.
5290 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5291 * acconfig.h: New comment text for above CPP symbol.
5292 * configure.in: Call it.
5293 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5295 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5297 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5298 testing for __EMX__.
5300 * posix.c: #include <libc.h>, if it exists.
5302 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5303 don't even know if the latter exists.
5305 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5306 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5307 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5309 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5311 (scm_init_posix): Use them when initializing the Scheme constants
5314 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5316 * Makefile.in (libdir, includedir, bindir): Use the
5317 autoconf-supplied values, instead of deriving them ourselves.
5318 (pkgincludedir, datadir, pkgdatadir): New variables.
5319 (install, uninstall): Put the header files in a special
5320 subdirectory, not in the main search path.
5322 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5323 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5325 * Makefile.in (IMPLPATH): Deleted; never used.
5327 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5328 on the Tcl/Tk source any more.
5329 (INCLUDE_CFLAGS): Remove references to the above.
5331 * Makefile.in (version.o): Corrected dependencies.
5333 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5335 * libguile.h: #include "version.h"
5337 * init.c (scm_boot_guile): Call scm_init_version.
5338 * gscm.c (gscm_run_scm): Call scm_init_version.
5340 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5341 GUILE_VERSION): AC_DEFINE these.
5342 (acconfig.h): #undef the above symbols.
5344 * Makefile.in (libobjs): Add version.o.
5345 (installed_h_files): Add version.h.
5346 (c_files): Add version.c.
5347 (gen_c_files): Add version.x.
5348 (version.o): New rule.
5349 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5350 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5351 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5352 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5353 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5354 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5355 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5356 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5357 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5358 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5359 weaks.o): Add version.h to dependency lists.
5360 (markers.o): Remove duplicate rule.
5362 * version.h: New file.
5364 * version.c: New file.
5366 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5368 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5369 array; use it appropriately. Since GCC is quite happy to
5370 subscript functions, it never warned us about this; we should use
5371 -Wpointer-arith in the future. I guess we never tested
5374 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5376 * socket.c: Doc and copyright fixes.
5378 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5380 * debug.c: Fixed and improved gdb support.
5382 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5384 * socket.c: Added declaration of inet_aton to avoid compiler
5385 warning. (Hope this solution is correct.)
5387 * stime.c: Added declaration of ftime. (This is missing in
5390 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5392 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5394 * Makefile.in (c_files): add strerror.c.
5396 * strerror.c: new file from Emacs' sysdep.c.
5397 maybe configure should also check for sys_errlist.
5399 * configure.in (AC_REPLACE_FUNCS): add strerror.
5401 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5403 * debug.c (scm_init_debug): Added initialization for
5404 scm_evaluator_traps.
5406 * debug.h, debug.c: Various name changes.
5407 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5408 "debug-options-interface". See commentary in options.c.
5410 * options.h, options.c: Options now have documentation strings.
5411 Also added a long explanatory commentary.
5413 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5416 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5417 last_debug_info_frame is now updated in all cases.
5419 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5422 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5424 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5425 Added option STACK_CHECKING.
5427 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5429 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5431 * __scm.h: Removed symbols for debugging support.
5433 * acconfig.h: Added symbols for debugging support.
5435 * configure.in: Added user option for debugging support.
5436 --enable-debug will include the debugging code into libguile.a.
5438 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5439 scm_relocate_chunk_to_heap.
5441 * debug.c: New file: low-level debugging support. It also
5442 includes support for debugging with gdb. (The extensions to gdb
5443 are written by Per Bothner at Cygnus.)
5445 * debug.h: New file: low-level debugging support.
5447 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5448 argument pairs. Extensive modifications to the debugging
5449 evaluator. Added "SECTION:" commentaries to clarify what happens
5450 when, during double compilation. Renamed EVALIMP --> EVALIM.
5451 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5452 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5453 the beginning of the file. New procedure: scm_unmemocopy.
5454 Added some global state variables needed by the debugging
5455 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5456 check_entry, check_apply, check_exit, debug_options and
5457 evaluator_traps. New acro: undefine.
5459 * eval.h: Renamed EVAL --> XEVAL.
5461 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5462 --> scm_make_weak_key_hash_table.
5464 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5465 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5467 * libguile.h: Conditionally include debug.h
5469 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5470 scm_object_properties shouldn't return handle. `handle' now gets
5471 initialized in scm_set_object_properties_x. scm_object_properties
5472 doesn't any longer create an entry in scm_object_whash.
5474 * options.c: New file: handling of run time options.
5476 * options.h: New file: handling of run time options.
5478 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5480 * print.c: New procedure: scm_print_options
5482 * print.h: Defines for print options.
5484 * read.c: New procedure: scm_read_options
5486 * read.h: Defines for reader options.
5488 * root.h: Added scm_source_whash among scm_sys_protects.
5490 * srcprop.c: New file: source properties.
5492 * srcprop.h: New file: source properties.
5494 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5495 (Bug found by A. Green.)
5497 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5499 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5501 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5503 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5505 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5506 and should be called by the final client.
5508 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5510 * gc.h: Use the PROTO macro when declaring functions.
5511 * gc.c: Use the PROTO macro when declaring static functions.
5512 Remove the CPP hair around function definitions.
5514 * gc.c (scm_init_storage): Initialize scm_asyncs.
5516 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5517 preprocessor symbol; "__scm.h" is where it might get #defined.
5518 * __scm.h: Similar: #include <scmconfig.h> before testing
5521 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5523 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5525 * init.c (scm_boot_guile): Add init_func argument; call
5526 (*init_func) instead of calling scm_appinit; it's ucky to
5527 hard-code names for the user's procedures.
5528 * init.h (scm_boot_guile): Adjust declaration.
5530 * __scm.h (PROTO): New macro, for declaring functions with
5533 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5534 eliminate all the __STDC__ conditionals.
5535 (scm_boot_guile): Add declaration.
5536 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5537 Remove __STDC__ conditionals around function definitions; the
5538 declarations in init.h will provide the same information, more
5541 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5542 complain about it in the error message; the error message is
5543 adequate without that note, and there's nothing the user can do
5546 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5548 * Makefile.in (ancillary): Drop def.sed.
5550 * posix.c (scm_init_posix): Use numeric values, rather than
5551 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5552 F_OK. The symbols aren't available on some systems, and I'm
5553 pretty sure their values are fixed by common widespread practice.
5554 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5556 More functions unavailable on some systems.
5557 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5558 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5560 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5561 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5562 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5563 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5564 stub that signals an error as the #else.
5566 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5568 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5570 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5572 * unif.c: include ramap.h.
5574 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5576 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5578 * ports.c: include sys/ioctl.h.
5580 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5582 * configure.in: check for sys/ioctl.h.
5584 * ports.c: include <malloc.h> not "malloc.h".
5586 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5588 * fports.c: remove ttyname and tmpnam declarations.
5590 * posix.c: fewer ttyname declarations.
5592 * fports.c: include <string.h> not "string.h".
5594 * init.c, ioext.c: include string.h and unistd.h.
5596 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5598 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5599 genio.c, simpos.c, vports.c: include string.h.
5601 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5603 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5605 (scm_addr_buffer_size): change type from scm_sizet to int.
5606 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5607 from scm_sizet to int.
5609 * error.c: include unistd.h.
5611 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5614 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5616 * __scm.hd, def.sed: deleted.
5618 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5620 Changes for NeXT, suggested by Robert Brown.
5621 * configure.in: Call AC_TYPE_MODE_T.
5622 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5623 NeXT. Put header file list in alphabetical order.
5624 * configure, scmconfig.h.in: Regenerated.
5625 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5627 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5630 * acconfig.h: New file, providing documentation for the CPP
5631 symbols defined in configure.in
5632 * acconfig-1.5.h: Removed; superceded by the above.
5634 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5636 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5638 * fports.c (scm_open_file): don't return #f, throw error.
5640 * ioext.c (fileno): renamed from %fileno.
5641 (soft-fileno): deleted.
5643 * ports.c (scm_port_revealed): don't need to check for -1 from
5645 (scm_set_port_revealed_x): return unspecified, not #f.
5647 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5649 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5651 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5653 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5655 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5657 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5658 This is necessary on Ultrix, and doesn't hurt portability.
5660 * Makefile.in (dist-dir): New target, implementing a new dist system.
5661 (installed_h_files): Put in alphabetical order.
5662 Remove duplicate entries for markers.h and unif.h.
5663 (c_files): Remove duplicate entries for markers.c.
5664 (ancillary): Renamed from anillery; all uses changed. Remove
5665 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5666 Remove all the ../doc/* files; doc/Makefile.in handles that.
5668 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5670 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5671 every if must have an else, or else the whole command has a
5672 non-zero exit code whenever the if's condition is false.
5674 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
5676 * posix.c: include string.h.
5678 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
5680 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
5683 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
5684 Remove leading % from scheme names.
5685 Do not return error values, call SCM_SYSERROR or similar.
5687 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
5689 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
5691 * struct.c (scm_init_struct): new file.
5693 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
5695 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
5696 (scm_list_head): added list-head for rapidly chopping argument
5697 lists off of longer lists (and similar).
5699 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
5701 * objprop.c (scm_object_property): assq the cdr of the whash
5702 handle for obj, not the handle itself.
5704 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
5706 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
5707 weak hash tables last of all marking to avoid an obscure gc bug.
5708 WARNING: circular lists stored in a weak hash table will hose us.
5710 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
5712 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
5713 new functions similar to scm_substring_move_left_x and
5714 scm_substring_move_right_x.
5716 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
5718 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
5721 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
5723 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
5725 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
5727 * strports.c (scm_strprint_obj): convenience function. C for
5728 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
5730 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
5731 removed to a separate library
5733 * init.c (scm_boot_guile): copied from guile-tcl.c.
5734 Initialization specific to tcl interpreters removed.
5736 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
5738 * ports.c (scm_ports_prehistory): size malloced here doesn't
5739 matter so long as it is non-0 (got rid of "* 4").
5741 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5743 * gscm.h: gscm_mkarray eliminated (presumably was not being used
5744 since its definition was bogus).
5746 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
5748 * mallocs.[ch]: back again (for rx at least).
5750 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5752 * ports.c: removed functions relating to the mapping between ports
5753 and descriptors. (That stuff is unix-specific and should be collected
5754 in a separate library).
5756 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
5757 (Tom Mckay@avanticorp.com)
5759 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
5761 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5762 handled correctly (SCM_FREEP was applied to them) -- test for
5763 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
5764 being overwritten with #f. (brown@grettir.bibliotech.com)
5766 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
5768 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
5769 for a specific symbol or for all symbols.
5771 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
5773 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
5774 keys and weak values confused).
5776 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
5778 * list.c (scm_last_pair): map '()=>'()
5780 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
5782 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
5783 Generalized assoc and hash-table functions.
5784 Factored pairs.c into multiple files.
5786 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
5788 * gscm.c (gscm_run_scm): got rid of objprop.
5790 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
