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.
6 (Thanks to John Redford and Charbel Jacquin.)
8 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
10 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
12 * eval.c (safe_setjmp): Remove this misunderstanding.
13 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
16 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
18 * libguile.h: Mark these as C declarations, for compilation by C++
21 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
22 __cplusplus clause. I seriously doubt this ever worked the way
23 the author seems to have intended.
25 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
27 Utterly needless cleanups to hopelessly messy code.
29 (scm_fflush): Moved to ...
30 * genio.c (scm_fflush): ... here, amongst all the other port
31 method invocation functions.
32 * genio.h, ports.h: The prototype moves too.
34 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
36 * backtrace.c (display_error_body): The current frame does not
37 always have a parent frame; consider a function called directly
38 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
41 * alloca.c (alloca): Undo yesterday's changes, and simply call
42 malloc directly for storage, and abort if we don't get what we
43 want. The situation is much simpler --- just call malloc. Emacs
44 has bizarre/evil requirements (signal handlers might malloc unless
45 you set this global flag, so you have to set the flag around all
46 calls to malloc) which we are certainly not going to conform to,
47 so we can do the simple and obvious thing.
49 * coop.c (coop_condition_variable_wait): Make this function
50 static. It's only useful internally --- you should never just
51 wait on a condition variable.
52 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
54 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
56 * unif.c (scm_array_set_x): Accept any kind of number as an
57 element for a uniform vector of doubles. This is more consistent
58 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
60 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
61 works; I can't conveniently test it myself. (Thanks to Dvid
62 Tillman for the bug report.)
66 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
67 from here, not from scm_compile_shell_switches (which is a pretty
69 (scm_load_startup_files): New function.
70 (scm_ice_9_already_loaded): Variable moved to here from script.c.
71 * script.c (scm_compile_shell_switches): Don't load the startup
73 (scm_ice_9_already_loaded): Variable moved.
74 * init.c (scm_load_startup_files): Prototype for new function.
75 * gh_init.c (gh_enter): Doc fix.
77 1998-10-03 <jimb@savonarola.red-bean.com>
79 Some anti-warning changes from Greg Harvey.
80 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
81 warnings when it doesn't understand our NORETURN declarations in
83 * posix.c (scm_mknod): Similar.
85 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
87 * posix.c (scm_getpwuid): If we can't find an entry, return our
88 own message, instead of using scm_syserror --- the getpwMUMBLE
89 functions don't set `errno' to anything interesting.
91 1998-10-03 <jimb@savonarola.red-bean.com>
93 Get rid of warnings from the cooperative threading system.
94 * threads.h (scm_single_thread_p, scm_yield,
95 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
96 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
97 scm_wait_condition_variable, scm_signal_condition_variable): Add
98 prototypes for these Scheme-visible functions.
99 * coop-defs.h (coop_next_runnable_thread,
100 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
101 Prototypes for these here, even though they're from iselect.c.
102 (coop_condition_variable_wait, coop_join): Add prototypes.
103 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
104 scm_threads_free_condvar): Make these smob functions static.
105 * coop-threads.h (coop_init): Give this a real prototype.
106 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
107 (coop_next_runnable_thread): No need to provide prototype; it's in
110 * scmconfig.h.in: .detarenegeR
112 * iselect.c, threads.c: Doc fixes.
114 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
116 * Makefile.in: Regenerated with a patched automake, to get
117 dependency generation right when using EGCS.
119 * inet_aton.c (inet_aton): Add prototype, to remove compiler
120 warning. (Thanks to Robert Pluim.)
122 * inet_aton.c (inet_aton): Reassure the compiler that the
123 arguments to the <ctype.h> macros are all unsigned characters, not
126 1998-10-03 <jimb@savonarola.red-bean.com>
128 Getting rid of more warnings...
129 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
130 today's change to ../configure.in.
131 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
132 * scmconfig.h.in: Regenertaded.de.,.__
133 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
134 (scm_localtime, scm_mktime): Use a const char * to manipulate the
137 * readline.c: Doc fix.
138 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
139 * readline.h (scm_filename_completion_function): Add prototype.
140 (scm_init_readline): Make this into a prototype.
142 * readline.c (scm_filename_completion_function): Use SCM_PROC to
143 declare this, instead of calling scm_make_subr manually.
145 1998-10-02 <jimb@savonarola.red-bean.com>
147 * readline.h (scm_init_readline): Add prototype for this.
148 (scm_init_readline): Make this a real prototype.
150 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
152 Warning fixes from Maciej Stachowiak:
153 * backtrace.h (scm_display_application, scm_backtrace): Add
155 * debug.c (scm_m_start_stack): Make this function static.
156 * fluids.h (scm_fluid_p): Add prototype.
157 * procprop.c (scm_i_procedure_arity): Make this function static.
158 * regex-posix.c (scm_regexp_error_msg): Make this function static.
159 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
160 * root.h (scm_dynamic_root): Add external prototype.
161 * scmsigs.h (scm_usleep): Add external prototype.
162 * script.h (scm_init_script): Use prototype, not K&R decl.
163 * stacks.h (scm_stack_id): Add external prototype.
164 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
166 1998-09-30 Mark Galassi <rosalia@cygnus.com>
168 * gh.h: took out the definitions of vset and vref, since they are
169 replaced by the proper vector routines that correspond to the R4RS
172 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
174 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
175 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
176 third argument, a C expression that should result in a SCM value,
177 which is used to initialize the variable. Reimplemented
178 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
181 * version.h (scm_libguile_config_stamp): Add prototype.
182 (From Maciej Stachowiak.)
184 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
186 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
187 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
189 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
191 * print.c (scm_iprin1): Rather than having one i, and using it in
192 several places, declare a fresh i local to each block where it is
193 used, and give it a signedness appropriate to its use in each case.
196 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
199 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
200 signed/unsigned clashes.
202 * posix.h (scm_tmpnam): Added prototype.
204 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
205 scm_make_subclass_object): Add external prototypes.
207 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
208 comparison is okay here.
210 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
212 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
213 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
215 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
218 * load.c (swap_port): Make this function static.
220 * load.c (scm_search_path): Make max_path_len and max_ext_len
221 unsigned, since they're compared against string sizes.
223 * load.c (init_build_info): Make i unsigned.
225 * ioext.h (scm_read_line): Add prototype.
227 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
228 scm_hash_fn_remove_x): Make hash bucket index local variable k
229 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
230 accurately as possible.
232 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
233 comparisons, and range checking to make sure those casts are
236 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
237 signed/unsigned comparisons.
239 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
240 avoid signed/unsigned comparisons.
241 * smob.h (scm_numsmob): Change extern declaration to match.
243 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
244 avoid signed/unsigned comparisons.
245 * ports.h (scm_numptob): Change extern declaration to match.
246 (scm_current_load_port, scm_set_port_line_x,
247 scm_set_port_column_x): New prototypes.
249 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
250 test code, and it causes warnings.
252 * gh.h (gh_int2scmb, gh_uniform_vector_length,
253 gh_uniform_vector_ref): Added prototypes.
255 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
256 debugging support unconditionally. That's backtrace.c, stack.c,
257 debug.c, and srcprop.c.
258 (EXTRA_libguile_la_SOURCES): Omit those from here.
259 * Makefile.in: Regenerated.
261 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
263 * options.c (scm_options): Bugfix: Allow empty list of options!
265 * debug.c, debug.h (scm_single_step): Removed.
266 (scm_with_traps): New procedure. This procedure could easily be
267 written in Scheme but needs to be highly optimized.
269 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
271 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
272 Check SCM_TRAPS_P before trapping.
274 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
276 Changes to avoid signed/unsigned comparison warnings.
277 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
278 (scm_gc_sweep): Make n and j local to the blocks they're used in,
279 so they can have appropriate types for each application. Make i
280 signed. Use initializers in some spots. I'll probably pay for
282 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
283 (scm_must_realloc): Make nm unsigned.
284 (init_heap_seg): Make new_seg_index and n_new_objects signed.
285 (scm_init_storage): Use prototype-style definition, and make the
287 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
288 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
290 * filesys.c (scm_readlink): Make local vars rv and size ints, to
291 avoid signed/unsigned comparison warnings, and because the return
292 value of readlink may be -1. Don't bother casting the third
293 argument to readlink.
295 * filesys.c (scm_dirname, scm_basename): Move these to their own
296 page, at the end of the file.
297 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
299 * eval.h (scm_eval_options_interface): Add external prototype for this.
300 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
302 * eval.c (scm_lookupcar1): Make this static.
304 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
305 Make these prototype declarations, not K&R-style.
307 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
308 unsigned comparison warning.
310 * appinit.c: File removed. It had a single function in it, empty,
311 whose reason for existence is explained in no documentation or
312 comment. I think it's there as a default for some Tcl-style
313 initialization, but Tcl abandoned that approach a while ago.
314 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
315 (BUILT_SOURCES): Remove appinit.x.
316 * Makefile.in: Regenerated.
318 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
320 * Makefile.in: Regenerated using the last public version of
321 automake, not the hacked Cygnus version.
323 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
325 Remove Totoro kludge.
326 * Makefile.in, scmconfig.h.in: Regenerated.
327 * init.c, readline.c: Don't check if TOTORO is #defined.
329 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
331 * Makefile.am: Adjust for new thread configuration system.
332 (INCLUDES): Include the value of THREAD_CPPFLAGS.
333 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
335 (THREAD_LIBS): Definition deleted; automake will generate such
336 things automatically.
337 * Makefile.in: Regenerated.
339 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
341 Simplify smob and port marking; set the mark bit in the generic
342 marking code, and make marker routines only responsible for
343 turning up outgoing pointers.
344 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
345 before calling the marking function. Don't call the marking
346 function if it's zero.
347 * markers.c (scm_mark0): Just return #f. This function isn't
348 necessary at all now, but it's harmless to call it. We'll leave
349 it in so other folks' code doesn't croak at link time.
350 (scm_markcdr): Don't call SCM_SETGC8MARK.
351 * async.c (mark_async): Don't call SCM_SETGC8MARK.
352 * dynl.c (mark_dynl_obj): Same.
353 * root.c (mark_root): Same.
354 * srcprop.c (marksrcprops): Same.
355 * unif.c (markra): Same.
356 * variable.c (scm_markvar): Same.
357 * ports.c (scm_markstream): Same.
358 (void_port_ptob): Specify zero for our marking function.
359 * debug.c (debugobjsmob): Same.
360 * dynwind.c (guardsmob): Same.
361 * filesys.c (dir_smob): Same.
362 * fluids.c (fluid_smob): Same.
363 * fports.c (scm_fptob, scm_pipob): Same.
364 * mallocs.c (mallocsmob): Same.
365 * regex-posix.c (regex_t_smob): Same.
366 * smob.c (freecell, flob, bigob): Same.
367 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
368 * throw.c (jbsmob, lazy_catch_funs): Same.
370 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
372 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
373 scm_copy_tree on code in order not to let memoized code to leak
374 out. Thus, scm_copy_tree needs to copy vectors as well since
375 quasiquote can introduce evaluated code also inside vector
378 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
380 * eval.c (scm_copy_tree): Removed ability to copy vectors.
382 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
383 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
386 * unif.c: Say that ivect and uvect are of type signed and unsigned
387 long instead of int in commentary so that it correctly describes
390 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
392 * stime.c: Removed declaration of strptime. (It should be
393 declared by the system headers. If it turns out that some systems
394 don't, we'll handle that then.) (Thanks to Greg Troxel.)
396 * stime.h: Renamed TIMEH --> STIMEH
398 * backtrace.c (scm_display_error, scm_display_backtrace): In order
399 to increase portability, don't use structure assignment.
400 (Thanks to Nicolas Neuss.)
402 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
404 (finalize_fd_sets): Added empty statement after last case label.
405 (Thanks to Nicolas Neuss.)
407 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
410 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
412 * init.c, readline.c: OK, I won't have these readline.x bug
413 reports anymore. We've had them since April. The current reason
414 is a completely unintelligible failure of totoro.red-bean.com to
415 do the test for rl_getc_function in libreadline correctly. This
416 kludge overrides the test if we're on totoro so that the snapshot
417 generation process can work.
419 * readline.c: Define a strdup replacement if not existent on system.
421 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
423 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
424 This change makes scm_make_vector R5RS compatible. We cannot keep
425 the third argument since people want to be able to deduce the form
426 of the C function call only by looking at R5RS. (At the same time
427 we have removed some unnecessary complexity!)
429 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
430 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
431 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
432 argument in call to scm_make_vector.
434 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
436 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
437 This macro is useful in applications.
439 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
441 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
442 (scm_parse_path, scm_search_path): New Scheme level procedures.
444 * load.h (scm_internal_parse_path, scm_parse_path,
445 scm_search_path): Declared.
447 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
449 * filesys.c (dirname, basename): New procedures.
451 * init.c (scm_boot_guile_1): Removed condition around
454 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
455 new data type (guards) for representation of C level guards and
456 data on the wind chain.
457 (scm_internal_dynamic_wind): New function.
459 * dynwind.h: Declare scm_internal_dynamic_wind.
461 * root.h (scm_root_state): Added scm_cur_loadp.
463 * root.c (mark_root): Added comment about cur_loadp.
465 * load.c: #include "dynwind.h";
466 (scm_primitive_load): Use scm_inner_dynamic_wind to update
469 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
471 * ports.c (current-load-port): New procedure.
473 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
475 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
476 not a tty, return #f.
478 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
479 to Julian Satchell and Roland Kaufmann.)
481 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
482 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
484 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
486 * debug.h, debug.c (scm_start_stack): New function. Implements
487 the guts of old scm_m_start_stack.
489 * debug.c (scm_m_start_stack): Use scm_start_stack.
491 * init.c (scm_start_stack, scm_restart_stack): Renamed to
492 start_stack and restart_stack. (These have static scope.)
494 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
496 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
497 readline functions to come in release 2.3. (Thanks to Chet
499 (handle_errors): Use the above functions.
501 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
503 * readline.c: Improvements for readline support: Handle errors
504 better; Implement before-read-hook.
506 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
508 * init.c (scm_boot_guile_1), readline.c: Test for
509 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
510 assure that we have version >= 2.1.)
512 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
514 * readline.c (scm_readline): Defer interrupts while we're calling
517 * readline.c (scm_add_history): Bugfix: Do strdup before giving
518 away the string to add_history.
519 (completion_function): Do completion for readline. (Thanks to
521 (scm_filename_completion_function): New procedure: Filename
523 (current_input_getc): New function. Use this one instead of
524 standard getc from readline.
526 * throw.c, throw.h (scm_handle_by_throw): New function: This
527 handler throws errors to next handler on the dynwind chain.
529 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
531 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
534 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
536 * procprop.c (scm_i_procedure_arity): New function. Returns arity
538 (scm_procedure_properties): Modified to return arity together with
540 (scm_procedure_property): Added the read-only property `arity'.
541 (scm_set_procedure_property_x): It is an error to set the `arity'
544 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
545 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
547 * procprop.h (scm_sym_arity): New symbol.
549 * objects.c (scm_set_object_procedure_x): New procedure: Use this
550 to set the dispatch procedure of an operator or entity object.
552 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
553 Made procedure slots read-only.
555 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
556 scm_tcs_cons_gloc case in zero args switch; Fixed args
557 construction for operators in scm_tcs_cons_gloc case in two args
560 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
562 * fluids.c: Removed use of assert.h (in order to avoid
565 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
567 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
569 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
570 change makes the evaluator safer at the cost of evaluation speed.
571 It handles the case when the user has added a non-immediate
572 improper end of the application form, e.g., `(+ 0 . x)'.
573 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
574 minimize the extra cost as much as possible. The new code is
575 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
576 problem with structs planted directly in the code (e.g. by a
577 macro). This no longer causes segmentation fault. (Thanks to
580 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
581 arg `proc' in order to be able to throw errors; New argument
584 * Removed extra #include "debug.h"
586 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
588 * scmsigs.c: Declare usleep as returning void on some systems.
589 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
592 * coop.c (usleep): Return void on some systems.
594 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
596 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
598 * coop.c: Changed return type of usleep to int.
600 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
601 isn't found in the OS.
603 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
604 isn't enabled. (Thought that I had made this change ages ago...)
606 * iselect.c: Declare bzero if not defined by OS.
608 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
610 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
611 condition. (Thanks to John Tobey.)
613 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
614 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
617 * __scm.h: Start the long-term project of moving to POSIX threads.
618 Phase 1: Classification of all critical sections.
619 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
620 for A sections. (See comments in __scm.h for details.)
622 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
623 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
625 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
627 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
628 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
629 (libpath.h, versiondat.h): Replaced dependency on Makefile with
630 dependencies on $(srcdir)/Makefile.in
631 $(top_builddir)/config.status in order to avoid circularity.
633 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
634 from argc if argc was 0 initially.
636 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
637 in generation of libpath.h.
639 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
641 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
642 libguile from 2 to 3.
644 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
646 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
648 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
650 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
651 scm_set_port_column_x, scm_port_filename,
652 scm_set_port_filename_x): Removed optional arguments. Added
653 proper argument checking.
655 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
656 stack size in machine words.
658 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
659 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
660 to Ole Myren Röhne.)
662 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
664 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
665 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
667 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
670 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
671 procedure apply: Copy argument lists before pushing them unto the
672 environment so that the environment won't get mutated due to
673 manipulation of procedure arguments. This should perhaps be
674 regarded as a temporary solution until someone finds a more
675 efficient one. (Thanks to Maciej Stachowiak.)
677 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
679 * script.c (scm_compile_shell_switches): Use "guile" as default
680 zero arg if argc is NULL.
682 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
684 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
685 is zero. (Thanks to Dirk Herrmann.)
687 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
689 * ports.c (scm_add_to_port_table): First line is now line 0
690 (was 1). (Interface changed according to suggestion by Per
693 * backtrace.c (display_header): Add 1 to line and column numbers
694 when presenting them to the user.
696 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
697 from debug.c --> eval.c
699 * eval.h, eval.c (scm_eval_options_interface): New options
701 (SCM_EVAL_STACK): New option: Size of newly created stacks,
702 i.e. stacks for new threads.
704 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
706 * eval.c (unsafe_setjmp): Removed with #if 0.
708 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
711 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
712 to avoid compiler warnings.
714 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
716 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
718 * throw.c (handler_message): Print message on current error port
719 instead of default error port. (Thanks to Maciej Stachowiak.)
721 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
723 * ports.c (scm_add_to_port_table): allocate in units of
724 struct scm_port_table *, not struct scm_port_table.
725 * posix.c (scm_close_pipe): remove the port from the port table
727 Thanks to Rob Engle for both fixes.
729 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
731 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
732 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
734 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
736 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
738 * backtrace.c (display_error_body, display_backtrace_body),
739 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
740 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
741 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
742 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
745 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
746 don't receive the jmpbuf arg anylonger.
747 (scm_catch): Don't accept a #f tag.
748 (scm_throw): Check that key is a symbol.
749 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
751 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
753 * async.c (async_pending): Removed declaration.
755 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
757 * dynwind.c (scm_wind_chain): New debug function.
759 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
760 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
761 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
762 extra layer of functions around the body and handler of a thread.
763 This extra layer makes sure that the handler is called in the
764 dynamic context of the surround (= empty dynwind list), but under
765 the *dynamic root* of the body. We can not use the dynamic root
766 of the surround since that root belongs to another thread => stack
767 is not handled correctly. It may seem ugly to use this extra
768 layer, but the extra cost in terms of execution time is really
769 negligible compared to the total amount of time required to create
770 a thread, and it would reduce maintainability to duplicate the
771 crucial and complicated steps performed by cwdr.
773 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
774 (SCM_ALLOW_INTS): Added thread switching code before interrupts
775 get re-enabled. The important effect of this is that interrupts
776 are blocked during thread switching so that thread data structures
777 don't risk getting messed up by an unfortunate signal.
778 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
779 seems to do more aggressive optimization which actually move
780 instructions around in these macros in a fatal way. Therefore:
781 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
782 just superstitious...)
783 (SCM_TICK): Maybe do a context switch and take care of asyncs.
784 This macro should be used instead of SCM_ASYNC_TICK since the
785 latter doesn't do context switches any more.
787 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
788 instead of SCM_ASYNC_TICK.
790 * coop.c, iselect.c: Since thread switches are now performed with
791 interrupts masked, we can't use the old mechanism of delivering
792 signals immediately when they arrive. Signals must instead be
793 delivered when the asyncs run *after* the end of the critical
794 section in scm_internal_select. But this also means after context
795 switch so that the signal will be delivered to a different thread.
796 To avoid this, I have changed the protocol of
797 coop_wait_for_runnable_thread and friends so that they are allowed
798 to return the original thread. So, if a signal arrives during
799 scm_internal_select, we won't any longer be forced do a context
800 switch, but can remain in the same thread and deliver the signal
803 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
804 scm_asyncs_pending and made it global.
806 * iselect.c: Small fixes.
808 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
809 coop_condition_variable_init, coop_condition_variable_wait,
810 coop_condition_variable_signal): Changed return type from `void'
811 to `int'. This is to adhere closer to the pthreads interface.
812 This, in turn, is part of an attempt to provide C versions of the
813 mutex and condition variable primitives which can be part of a
814 frontend to COOP or pthreads.
816 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
817 coop_condition_variable_destroy): New functions.
819 * coop-threads.c (scm_wait_condition_variable): Use
820 coop_condition_variable_wait_mutex.
822 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
823 Definitions moved to coop-defs.h.
825 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
826 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
827 scm_cond_destroy): New C interface to mutecis and cond vars.
829 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
831 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
833 * iselect.c: Now several threads can wait on the same file
834 descriptor. The behaviour is compatible with OS select: All
835 threads waiting for the fd return with the same status.
837 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
839 * coop-threads.c, threads.h (scm_spawn_thread): New function.
840 Can spawn a thread from application C code.
842 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
844 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
845 gh_doubles2scm): New functions.
847 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
849 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
850 commented-out version of gh_eval_str()
852 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
854 * socket.c (scm_bind): free soka after use.
856 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
858 * stime.c (tzvar): new variable.
859 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
860 avoid memory leaks when allocating.
862 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
864 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
867 * gc.c, tags.h: Doc fixes.
869 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
871 * eval.c (macro-eval!): Removed. This function was a design bug.
872 It allowed memoized code to leak out to the scheme level. Most
873 things that you could do with `macro-eval!' can be done with
876 1997-12-20 Tim Pierce <twp@skepsis.com>
878 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
879 scm_fgets now depends on ftell(3) to know how many bytes were
882 1997-12-15 Tim Pierce <twp@skepsis.com>
884 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
885 dealing with strings.
887 1997-12-13 Tim Pierce <twp@skepsis.com>
889 Make %read-line more suitable for implementing read-line efficiently.
890 * ioext.c (scm_read_line): Strip the terminating newline from a
891 string, and return a cons of the string and its terminator.
893 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
894 of the string that is read is stored in this memory location.
895 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
896 * genio.c, genio.h (scm_do_read_line): Update caller.
897 * ports.h (scm_ptobfuns): Update typedef.
898 * fports.c (scm_fptob, scm_pipob): Update struct.
900 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
902 * filesys.c (set_element): Return file descriptor.
903 (fill_select_type): Return the highest file descriptor.
904 (scm_select): Tell select about the highest file descriptor. On
905 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
906 Therefore the extra overhead for calculating the maximum fd seems
907 to be more than compensated. Is this correct? In any case,
908 scm_internal_select will be much faster with this info.
909 (scm_select, fill_select_type, set_element): Don't accept any kind
910 of object in the file descriptor list or vector.
912 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
914 * iselect.c (finalize_fd_sets): Bugfix.
916 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
918 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
919 when using scm_internal_select (since we might switch to another
922 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
924 * simpos.c (scm_system): always define: use sysmissing if not
925 available. Check for HAVE_SYSTEM instead of _Windows (does
926 Windows lack system or does it have an unusable one?).
927 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
928 Let the argument be optional: if not supplied, call system(NULL).
930 * ports.c (scm_close_port): relax the type check from OPPORTP to
931 PORTP; closing a closed port is allowed.
933 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
935 * fports.c (scm_fgets): Return if the last char in a chunk is
936 newline. When fgets returns a string whose length is `size-1', it
937 is ambiguous whether a whole line was retrieved, so we must check
938 explicitly whether a line terminator is present.
940 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
942 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
943 before taking the CDR. (Thanks to Harald Meland.)
945 * filesys.c (scm_stat): Slightly optimized.
947 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
949 * ports.c (scm_close_port): Make sure the port is open before
952 * guile-snarf.in: Pass args through to gcc in a way that preserves
953 whitespace boundaries. (Thanks to Greg Badros.)
955 1997-12-02 Tim Pierce <twp@skepsis.com>
957 * stacks.c (scm_frame_procedure): Reverse the logic in the return
958 statement. (Thanks to Doug Evans for pointing this out.)
960 1997-12-01 Tim Pierce <twp@skepsis.com>
962 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
964 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
966 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
967 errno macro expansion of this field name. (errno is a C
968 preprocessor macro on some systems.)
970 1997-11-29 Tim Pierce <twp@skepsis.com>
972 * iselect.c: Doc fix.
974 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
976 * init.c (scm_start_stack): Removed initialization of
977 scm_the_last_stack_var.
979 * backtrace.h: Declare scm_the_last_stack_var.
981 * backtrace.c: Define scm_the_last_stack_var.
983 * root.c (mark_root): Don't mark the_last_stack_var.
985 * root.h (scm_root_state): Removed the_last_stack_var.
987 * throw.c: Added #include "fluids.h"
988 (ss_handler): `the-last-stack' is now a fluid.
990 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
991 --> the_last_stack_fluid.
993 * backtrace.c: Added #include "fluids.h"
994 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
995 (scm_backtrace): `the-last-stack' is now a fluid.
997 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
998 after scm_init_fluids.
1000 1997-11-28 Tim Pierce <twp@skepsis.com>
1002 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1004 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1005 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1007 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1009 * iselect.c (coop_next_runnable_thread,
1010 coop_wait_for_runnable_thread): Disable interrupts so that no
1011 async is executed before a potential error_revive.
1012 (scm_internal_select): Disable interrupts during the parts of the
1013 code which manipulate the sleep queue and the file descriptors.
1015 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1017 * Makefile.am: Added iselect.c and iselect.h.
1019 * coop.c (coop_qinit): Initialize fields used by
1020 scm_internal_select.
1021 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1022 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1023 replacement in iselect.c.
1024 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1025 coop_join): If GUILE_ISELECT enabled, use
1026 coop_wait_for_runnable_thread instead of
1027 coop_next_runnable_thread.
1028 (usleep, sleep): New replacements for system functions if
1029 GUILE_ISELECT is enabled.
1031 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1033 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1035 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1036 iselect.h. Implement Scheme level `select' using
1037 scm_internal_select. (See NEWS.)
1039 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1041 * init.c: Call scm_init_iselect.
1043 * iselect.h, iselect.c: New files. Implements
1044 scm_internal_select. (See NEWS.)
1046 1997-11-27 Tim Pierce <twp@skepsis.com>
1048 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1049 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1050 and scm_must_free, since ultimately the string returned will be copied
1051 by scm_makfrom0str anyway. Also, read any characters that may have
1052 been pushed onto the port with scm_ungetc.
1053 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1054 * ioext.c (scm_read_line): Free string after Guilifying it.
1055 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
1057 1997-11-26 Anthony Green <green@hoser.cygnus.com>
1059 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1061 * gh.h: Safely wrap prototypes for c++ usage.
1063 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1065 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1066 gh_repl (argc, argv).
1068 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1070 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1071 and to invoke scm_shell().
1072 (gh_launch_pad): took out the loading of boot-9.scm from here,
1073 since it is probably best to let the user control that. In fact,
1074 gh_repl() now invokes scm_shell() which does that.
1076 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1078 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
1081 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
1083 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
1084 yesterday's underscore patch. (Thanks to Marius Vollmer for
1087 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
1089 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
1090 DLSYM_ADDS_USCORE is not defined.
1092 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
1094 * gh_data.c (gh_uniform_vector_length):
1095 (gh_uniform_vector_ref): started implementing the uniform types in
1098 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1100 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1101 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1103 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1105 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1106 configure.in was changed).

1110 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1111 * Makefile.in: Regenerated.
1113 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1115 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1116 OPORT is an `open' port, not an output port.
1118 * filesys.c (scm_close, set_element, get_element, scm_chown,
1119 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

1123 scm_port_column, scm_set_port_column_x, scm_port_filename,
1124 scm_set_port_filename_x, scm_port_mode,
1125 scm_close_all_ports_except, scm_set_current_output_port,
1126 scm_set_current_error_port): Likewise
1127 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1128 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1130 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1131 * backtrace.c (display_backtrace_body): Likewise
1132 * fports (scm_setvbuf): Likewise
1133 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

1136 * unif.c (scm_uniform_array_write): Likewise
1138 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1140 Minor problems with substring-related tag changes.
1141 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1142 exactly what we want to leave in to detect substrings.
1143 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1144 * tags.h: Fix diagrams and comments describing the S tag bit;
1145 remove vestigial remarks about the D tag bit.
1146 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1147 * strings.c: Formatting tweaks.
1149 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1150 variable first; then SCHEME_LOAD_PATH, with a warning message.
1151 (scm_parse_path): New function.
1152 * script.c: Doc fixes.
1154 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1156 Readline support, from Daniel Risacher.
1157 * readline.c, readline.h: New files.
1158 * init.c: #include "readline.h".
1159 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1160 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1161 * Makefile.in: Regenerated.
1162 * scmconfig.h.in: Regenerated, after change to ../configure.
1164 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1166 * gh.h: gh_vector_set -> gh_vector_set_x
1168 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1170 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1171 with the ! -> _x mapping when going from Scheme to C.
1173 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1175 * gh.h (gh_reverse):
1183 (gh_assoc): added these gh_ functions implemented as macros.
1185 * gh_predicates.c (gh_null_p):
1186 (gh_string_equal_p): added these two missing predicates.
1188 * gh_list.c (gh_append):
1193 (gh_set_cdr_x): added these routines as I go through and try to
1194 complete the picture R4RS functions that should be mirrored in the
1197 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1199 * tags.h (scm_tc7_substring): Changed the comment and code to
1200 conform with the changes below. Folks! We have suddenly two new
1201 free tc7 codes!!! Jummy, jummy!
1203 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1205 * Makefile.in: Rebuilt.
1206 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
1208 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
1209 * unif.c (scm_vector_set_length_x): Don't handle multibyte

1224 * tags.h (SCM_TYP7SD): Removed.
1225 (SCM_TYP7D): Removed.
1226 (scm_tc7_mb_string): Removed.
1227 (scm_tc7_mb_substring): Removed.
1228 * print.c (scm_iprin1): Handle char printing directly. Don't
1230 Don't include "mbstrings.h".
1231 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1232 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1234 Don't include "mbstrings.h".
1235 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1236 (SCM_SYMBOL_SLOTS): Define as 4.
1237 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
1238 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
1239 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
1240 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
1241 struct.c, threads.c, throw.c, unif.c, variable.c: Use new
1242 ("gen"-less) I/O function names.

1258 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
1259 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
1261 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1263 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1265 * gh_test_c.c (c_vector_test): some improvements on the vector
1268 * gh.h (gh_vector): this used to exist but do the wrong thing.
1269 Now it (almost) does the right thing, though it takes a list
1270 instead of the individual arguments. I need to see how it could
1272 (gh_list_to_vector): added this function as a macro. Corresponds
1273 to Scheme's (list->vector ...).
1274 (gh_vector_to_list): added this function as a macro. Corresponds
1275 to Scheme's (vector->list ...).
1277 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1278 gh_vector_ref, so that it resembles the Scheme routines more.
1279 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1280 resembles the Scheme routines more.
1281 (gh_make_vector): this used to be (stupidly) called gh_vector().
1282 This is the right name, since it does the same thing as the Scheme
1283 (make-vector ...) procedure.
1285 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1287 * ports.h: #include "libguile/print.h"
1289 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
1290 Some indentation fixes.
1292 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1293 longer a user field; New field: class_flags.
1295 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1297 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1299 * gh_data.c (gh_bool2scm): new function which replaces
1300 gh_int2scmb(), which is now tagged as obsolete.
1302 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1304 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1305 macros should by convention not test for NIMPness.)
1306 (SCM_COERCE_OPORT): Adjust indentation.
1308 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1309 SCM_NIMP test before SCM_PRINT_STATE_P.
1311 * struct.c, struct.h, gc.c: Renamed:
1312 scm_struct_i_layout --> scm_vtable_index_layout
1313 scm_struct_i_vcell --> scm_vtable_index_vcell
1314 scm_struct_i_vtable --> scm_vtable_index_vtable
1315 scm_struct_i_printer --> scm_vtable_index_printer
1316 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1318 * struct.c (scm_print_struct): Use new printer slot; Default
1319 printing: Also output hex code of vtable so that type identity
1320 will be indicated as well.
1321 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1322 Removed struct_printer_var; Removed struct-vtable-offset;
1323 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1324 vtable-offset-user): New constants.
1326 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1327 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1328 If this slot contains a procedure, use that to print structures of
1329 the type represented by this vtable.
1331 * print.c (scm_iprin1): Don't print arguments of macro
1332 transformers. (They are always: exp env.); Bugfix: Unmemoize
1333 transformer source with correct environment.
1335 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1337 Streamlining of call-with-dynamic-root:
1339 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1340 there is now only one catch.
1341 (cwdr_outer_body): Removed.
1342 (cwdr_handler): New function.
1343 (scm_internal_cwdr): New function to perform the function of cwdr
1344 but take args that are more useful to C code. Also, the handler
1345 is now invoked *outside* of the new dynamic root, like the docs
1346 say. We no longer have to catch absolutely all errors, the caller
1347 is responsible for using a handler that does not throw, if he
1349 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1350 * root.h (scm_internal_cwdr): New prototype.
1352 Even more but risky streamlining:
1354 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1355 allocation of the jumpbuf of a root continuation. The changes
1356 below are controlled by it. They are now deactivated.
1357 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1358 the JMPBUF of the scm_rootcont to NULL before returning.
1360 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1361 when they are non-NULL.
1362 (scm_gc_mark): Likewise, mark only when non-NULL.
1364 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1365 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1367 * gc.c (scm_done_malloc): New function.
1368 gc.h (scm_done_malloc): New prototype.
1370 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1371 (struct scm_print_state) [revealed]: New field.
1372 (scm_print_state_vtable): Make visible to the outside world for
1373 type checking purposes.
1374 (scm_valid_oport_value_p): New prototype.
1376 * print.c (scm_valid_oport_value_p): New function to check whether
1377 a certain value is acceptable as a port argument.
1378 (scm_print_state_vtable): New variable.
1379 (scm_free_print_state): Set `revealed' field to false.
1380 (scm_iprin1): Call user supplied closure printer with
1381 scm_printer_apply. Print in the traditional way when there isn't
1382 one or when it returns #f.
1383 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1384 Accept a port/print-state pair in addition to just a port.
1385 (scm_prin1): Don't return the print_state to the pool when it has
1387 (scm_printer_apply): Set `revealed' field of print_state to true.
1388 (scm_init_print): Set scm_print_state_vtable.
1389 (print_state_fluid, print_state_fluid_num): Removed.
1391 * throw.h (scm_handle_by_proc_catching_all): New prototype
1392 throw.c (scm_handle_by_proc_catching_all): New function
1394 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1396 * Makefile.in: Regenerated with automake 1.2c.
1398 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1400 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1401 was looping endlessly.
1403 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1405 * strports.c (scm_eval_string): Don't close the port.
1407 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1408 former returns a nice normal integer. (Thanks to Daniel
1411 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1413 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1414 makefile variable as a build parameter called LIBS. The
1415 build-guile program will use this, for the time being.
1416 * Makefile.in: Regenerated.
1418 Thanks to Shiro Kawai:
1419 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1420 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1423 * Makefile.in: Regenerated with automake 1.2a.
1425 * script.c (scm_compile_shell_switches): If we hit the -c or --
1426 arguments, don't set the car of (command-line) to scm_usage_name,
1427 the prettified name of the guile executable; give it the full
1428 path, the way shells usually handle $0.
1430 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1432 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1433 Scheme-level name `array-map' and renamed `serial-array-map' to
1434 `serial-array-map!'.
1436 * backtrace.c: Introduced exception handlers which now enclose
1437 `display-error' and `display-backtrace' so that error reporting
1438 won't get into infinite loops if an error occurs during displaying
1439 of the error. This can very easily happen with user supplied
1440 print call-back routines.
1442 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1444 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1445 the names `serial-array-map' and `array-map' should be removed.)
1447 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1449 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1450 Added #include "objects.h"
1452 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1453 Add #include "feature.h".
1455 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1456 (modinclude_HEADERS): Added objects.h.
1458 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1459 This test is needed at many places in the code and should be
1460 abstracted. (Motivated by the need of this test in libguiletk.)
1462 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1463 (scm_eval_string), load.c (scm_primitive_load,
1464 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1465 Use SCM_EOF_OBJECT_P.
1467 * eval.c (scm_init_eval): Add feature `delay'.
1469 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1471 * scmhob.h: Removed.
1473 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1475 * list.h (SCM_LISTn): New macros. Make list creation in C code
1476 prettier. The idea comes from STk.
1478 * sequences.h, sequences.c, append.h, append.c: Removed. These
1479 files implemented non-R4RS operations which would encourage
1480 non-portable programming style and less easy-to-read code.
1482 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1485 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1486 sequences.h, #include append.h.
1488 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1491 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1493 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1495 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1497 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1499 * eval.c: Added #include "objects.h"
1501 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1504 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1505 adjacent smob numbers.
1507 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1509 * procprop.h: Added declaration of scm_i_inner_name.
1511 * gsubr.c: New global symbol scm_i_inner_name.
1513 * debug.c (scm_procedure_name): Try procedure property
1514 `inner-name' if `name' fails.
1516 * print.c (scm_iprin1): Use scm_macro_name.
1518 * eval.c (scm_m_define): Give names to macros as well; Only the
1519 first top-level definition gives a procedure/macro a name.
1520 Otherwise confusing names can turn up in backtraces.
1521 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1522 `name'; Give names to macros as well.
1524 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1525 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1528 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1530 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1532 (prinmacro): Removed. The code has been moved/merged into print.c
1533 in order to decrease code redundancy. We want macros to print in
1534 a way equivalent to procedures, and it would be silly to duplicate
1535 the required code. (We don't want to maintain two places.)
1536 (macrosmob): Print field is now a NULL pointer.
1538 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1539 scm_macro_transformer): New prototypes.
1540 (scm_tc16_macro): Declared.
1542 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1543 are now printed in a way equivalent to procedures.

1554 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1556 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,

1558 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1559 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1560 SCM_BOOL_T. Any non-false value is true.
1562 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1564 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1565 scm_gensym): Added prototypes.

1581 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1583 * Makefile.in: Regenerated.
1585 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1587 * Makefile.in: Regenerated, so it uses "tar", not "gtar".

1600 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1601 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,

1609 * errno.h: prototype for scm_strerror.
1610 * error.c (scm_strerror): new procedure.
1612 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1614 * list.c (scm_list_append_x): Allow non-pair as last argument.
1615 This is consistent with the R4RS append and is probably the
1616 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1618 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1620 * stime.h: prototype for scm_times.
1621 * stime.c (scm_times): new procedure.

1638 third argument is now optional.
1640 * posix.c (scm_execl, scm_execlp): make the filename argument
1641 compulsory, since omitting it causes SEGV.
1642 (scm_sync): return unspecified instead of #f.
1643 (scm_execle): new procedure.
1644 (environ_list_to_c): new procedure.
1645 (scm_environ): use environ_list_to_c. disable interrupts.
1646 (scm_convert_exec_args): take pos and subr arguments and
1647 improve error checking.
1649 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1651 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1652 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1653 argument to SCM_ASSERT. Furthermore, the name of the function
1654 should be passed as first argument when signalling
1655 SCM_WNA. (Thanks to Thomas Morgan)
1657 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1658 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1659 dispatches on the number of actual args has a default case
1660 reporting an internal error. This is a vestige from a version
1661 that mallocated a SCM vector to hold the arguments. In the
1662 current version this check is too late: if it ever happens we will
1663 have already overstepped the bounds of the array.
1665 Also, the patch [...] adds a check for too many actual arguments."
1667 mdj: Removed check for "internal programming error".
1669 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1671 * gh_io.c (gh_write): New function.
1673 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1674 throw.c (scm_internal_stack_catch): New sibling to the other catch
1675 functions. Code moved from gh_eval.c.
1676 throw.h: Added header.
1677 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1678 scm_internal_stack_catch.

1684 Scheme name is now dup->fdes.
1685 (scm_dup_to_fdes): make the second argument optional and
1686 fold in the functionality of scm_primitive_dup.
1687 (scm_primitive_dup): deleted.
1689 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1691 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1692 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1693 ultrix are defined. Use setvbuf instead of setbuf.
1694 (scm_setvbuf): new procedure.
1695 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1696 (scm_setfileno): moved from ioext.c.

1710 (scm_init_print): Initialize them.
1711 (scm_iprin): If print_state_fluid carries a print_state, use that
1712 instead of creating a new one.

1714 definitions to help with calling printer functions written in
1716 * print.h (scm_printer_apply): New prototype.

1729 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1730 SCM_ASSERT: arg comes before pos.
1732 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1734 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1735 to a list of length zero correctly.
1737 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

1759 stream has been set.
1760 (scm_duplicate_port): deleted, there's now an implementation in

1813 data. (dynl_smob): Use it.
1814 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1815 the dynamic object data below the linking of the object to avoid
1816 memory leak when the linking code throws an error. Now the code
1817 leaks a whole dynamically linked library when must_malloc throws,
1818 but that should be much less likely.
1820 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1822 Changes to compile under gnu-win32, from Marcus Daniels:

1863 DEBUG_EXTENSIONS isn't #defined.
1865 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

1893 turn off REG_EXTENDED.
1894 (scm_init_regex_posix): New regexp/basic symbol.
1895 (REG_BASIC): #define this if it is not already present.

1942 (cwdr_outer_body): New function, to establish the user's handler,
1943 and pass control to cwdr_inner_body.

1955 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
1956 the feeling that real thread systems will not need this...
1958 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
1960 Try to detect when people are using one version of libguile and a

2000 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2002 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2003 argument plain char *.
2004 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2006 * tag.c (scm_tag): Remove unreachable statement.
2007 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2008 top of the word, it should be unsigned.
2010 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2011 is defined, to avoid warnings; it's only used in the
2012 conflict-checking code. Which might go away anyway.
2013 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2014 conditionals; put the label definition in an #if too, to stifle
2017 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2018 ChangeLog-threads in the distribution.
2019 * Makefile.in: Regenerated.
2021 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2023 * guile-snarf.in: Changed regexp to support CPPs that insert
2024 whitespace between lexical tokens (which munges the `%%%' snarf
2027 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2029 * load.c (scm_init_load_path): Append $(datadir)/guile to
2030 %load-path, so modules do not have to be installed in Guile's
2031 current version directory.
2033 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2035 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2036 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2037 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2038 call the sysdep functions with deferred ints.
2039 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2040 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2041 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2044 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2047 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2049 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2051 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2053 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2056 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2058 * eval.c (scm_lookupcar1): New procedure to cope with a race
2059 condition during lookup (when using threads).
2060 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2061 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2064 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2066 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2067 supplied. (Change from Tim Pierce.)
2069 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2071 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2072 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2073 default and not `()'. `#f' is the canonical non-value in Scheme,
2076 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2078 * struct.c (struct_printer): New variable that holds a handle on
2079 the Scheme variable *struct-printer*. This variable can be set by
2080 Scheme code to override the printing of structures.
2081 (scm_print_struct): If struct_printer is set, call it. If it is
2082 not set, or returns #f, print the structure in the old fashion.
2083 Include "eval.h" for scm_apply.
2085 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2087 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2088 scm_struct_i_n_words to get the number of fields, not
2089 -scm_struct_n_extra_words.
2091 On the route to fancier struct printing:
2092 * struct.c (scm_print_struct): New function to print a structure.
2093 Include "genio.h" to support it. This function doesn't do
2094 anything interesting right now, but I think it should be here
2096 * struct.h: Include "print.h" and add prototype for
2098 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2099 print structures ourself.
2101 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2103 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2104 before applying the handler in case it doesn't return.
2106 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2108 * scmsigs.h, async.h: updated.
2110 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2113 * posix.c (scm_uname): interpret only negative values as an error.
2114 Solaris normally returns a positive value.
2116 * script.c (scm_compile_shell_switches): if we are not going into
2117 an interactive repl, set scm_mask_ints to zero so that asyncs can
2120 * simpos.c (scm_system): don't ignore/unignore signals around
2123 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2126 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2127 done in boot-9.scm instead.
2129 * scmsigs.c, async.c: Major rewriting of signal handling code.
2130 (scm_sigaction): new procedure.
2131 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2133 (scm_raise): return unspecified, throw error on failure.
2135 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2137 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2138 feature, to help boot-9.scm decide whether to import the regex
2141 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2143 * eval.c: Include scmconfig.h at the beginning of the file so that
2144 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2147 * regex-posix.c: #include "_scm.h" before conditionally #including
2148 <regex.h>; the former defines HAVE_REGCOMP.
2150 * regex-posix.c: #include <regex.h> conditionally, so the file is
2151 CPP'able (for dependency scanning) even on systems that don't have
2154 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2156 Add new R4RS-compliant syntax for keywords.
2157 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2158 regardless of the setting of the `keywords' read option.
2159 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2160 can be re-read no matter what the setting of the `keywords' read
2163 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2165 Add support for POSIX regular expressions.
2167 * regex-posix.c, regex-posix.h: New files. (Some code
2168 is taken liberally from rx/rgx.c in the old Guile dist.)
2170 * init.c: Include regex-posix.h.
2171 (scm_boot_guile_1): Call scm_init_regex_posix.
2173 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2174 Add regex-posix.[ch] sources.
2175 * Makefile.in: Regenerated.
2177 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2178 to do this automatically? It didn't for me, bleh.)
2180 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2182 * fports.c (print_pipe_port): New function.
2183 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2184 latter doesn't even take the right arguments.
2186 * Makefile.am: Increment shared lib revision number. I think
2187 sometimes the uninstalled Guile finds the installed shared lib;
2188 Gord says doing this might help. As things turned out, I can't
2189 say whether it does.
2190 * Makefile.in: Regenerated.
2192 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2193 passing it as the closure argument to scm_boot_guile. (Bill
2196 * ports.c (print_void_port, putc_void_port, puts_void_port,
2197 write_void_port, flush_void_port, getc_void_port, close_void_port,
2198 noop0): Use ANSI prototypes instead of K&R declarations, so the
2199 initialization of void_port_ptob gets aggressively type-checked.
2200 Fix arguments of print_void_port and write_void_port. (Bill

2234 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2236 * script.c (scm_find_executable): Use prototype-style definition
2237 here; apparently it's not quite right to have const in a prototype
2238 and then use a K&R declaration. I wonder if stuff like this will
2239 go away if we compile with -Wrequire-prototypes, or whatever that
2240 is... (Bernard URBAN)
2242 * scmhob.h: New text from Bernard URBAN.
2244 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2246 * script.c: Don't #define const on hpux. Configure takes care of
2247 this. (Thanks to Larry Schwimmer.)
2249 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2250 decide whether to #include <unistd.h>, instead of listing a bunch
2251 of systems. Don't #include stdio twice. Removed dyked-out
2252 definition of scm_find_impl_file.
2254 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2256 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2257 library version info to 1:0.
2258 * Makefile.in: Regenerated.

2264 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2265 throw.c: Update copyright years; these files have been worked on
2266 significantly in 1997, but only had copyright years for 1996.
2267 Also, change name of copyright holder on some from Mikael
2268 Djurfeldt to Free Software Foundation; he has signed papers
2269 assigning the changes to the FSF.
2271 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2272 reason not to give the user the option.
2274 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2275 Return #f on end-of-file when scanning table (i.e. when called
2276 with no arguments). Try to catch errors, when we can.
2277 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2279 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2280 external declarations. These are useful.
2282 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2284 * posix.c: don't include <sys/select.h> or define macros for
2285 select, since they were not used in this file.
2287 * filesys.c (scm_select): make the fifth parameter microseconds,
2288 not milliseconds. let the fourth parameter be either a real value
2289 or an integer or #f. The first, second and third arguments can
2290 now be vectors: the type of the corresponding return set will be
2292 (set_element, get_element): new static procedures.
2294 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2296 * strports.c (scm_eval_string): New function.
2297 (scm_eval_0str): Trivially re-implemented in terms of
2299 * strports.h (scm_eval_string): New extern decl.
2301 * net_db.c (h_errno): Add extern decl for this.
2303 * fports.c (local_pclose): New function.
2304 (scm_pipob): Use it in the initializer here.
2307 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2308 Use a meaningful error message when signalling an error. For
2309 this, scm_gethost must check h_errno rather than errno.
2311 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2313 * Makefile.in: Regenerated, using automake-1.1p.
2315 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2317 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2318 not SCM_UNSPECIFIED.
2320 * script.c (scm_compile_shell_switches): don't append (quit) if
2322 (scm_shell): call scm_exit_status and exit on the result of the
2325 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2327 Ensure that shared substrings are handled properly when passed to
2328 a system call or other foreign function. Many thanks to Tim
2330 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2331 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2332 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2333 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2335 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2336 (scm_display_error_message): use RO macros when strings may be RO.
2337 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2338 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2339 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

2344 scm_strftime), vports.c (scm_make_soft_port): use
2345 SCM_COERCE_SUBSTR to make sure shared substrings are
2348 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2350 * error.c (scm_error): Add newline to error message.
2352 * init.c (scm_init_standard_ports): Doc fix.
2354 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2356 * dynl-shl.c: Completely replaced with new code from Bernard
2359 * script.c (scm_ice_9_already_loaded): New variable.
2360 (scm_compile_shell_switches): Use it.
2362 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2364 * filesys.c (scm_input_waiting_p): add missing third argument to
2367 * stime.c (scm_localtime): copy the result of localtime before
2368 calling gmtime in case they share a buffer.
2369 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2372 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2374 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2376 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2378 * Makefile.am (check-local): New target, which causes 'make check'
2379 to run gh_test_c and gh_test_repl, with some trivial input.
2380 * Makefile.in: Rgnrtd.
2382 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2384 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2387 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2389 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2390 sure how this was supposed to work.
2391 (scm_async_click): don't send SCM_TICK_SIGNAL.
2392 (scm_init_async): don't initialize %tick-thunk.
2394 * the following change doesn't affect the Scheme interface:
2395 gc-thunk is called at the end of garbage collection. however it's
2396 no longer implemented by pretending it's a signal.
2398 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2399 system async corresponding to scm_gc_thunk.
2400 * async.h: declare scm_gc_async.
2401 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2402 gc-thunk directly, instead of going through a signal handler.
2403 (scm_gc_async): new variable, points to the GC system-async.
2404 (scm_init_async): save the GC async as scm_gc_async instead
2405 of using system_signal_asyncs.
2406 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2408 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2410 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2411 Don't screw up if we're interrupted.
2412 * Makefile.in: Regeneradet.
2414 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2416 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2418 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2419 we're not using AM_INIT_GUILE_MODULE any more.
2420 * Makefile.in: Reneregated.
2422 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2424 Functions for finding variable bindings, grace à Tim Pierce.
2425 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2426 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2428 Get 'make dist' to work again.
2429 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2430 * Makefile.in: Regenerated, like a surry without a fringe on top.
2432 Changes for reduced Guile distribution: one configure script,
2434 * configure.in, configure: Removed.
2435 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2436 real configure script lives.
2437 * Makefile.in, scmconfig.h.in: Regenerated.
2439 * init.c: #include "script.h", to get prototype for script.c's
2442 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2444 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2445 scm_must_malloc, not raw malloc.
2447 * script.c (scm_compile_shell_switches): Dyke out debugging output
2450 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2452 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2454 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2455 system has them. Hope this is safe. Previously
2456 sys/timeb.h was included if HAVE_FTIME was defined or if
2457 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2458 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2460 * ioext.c (scm_setfileno): add missing third argument to
2461 scm_misc_error call.
2463 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2465 * eq.c (scm_equal_p): Correctly compare strings of different
2466 varieties. (Thanks to Tim Pierce.)
2468 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2470 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2471 #! block comment must occur on a line all by itself.
2473 Move most of the guts of shell command processing into libguile,
2474 so guile.c can be very small (and eventuallly auto-generated. (I
2475 mean, generated mechanically, not self-generated. Hmm.))
2476 * guile.c, script.c, script.h: New source files.
2477 * init.c (scm_boot_guile_1): Call scm_init_script.
2478 * libguile.h: #include "script.h".
2479 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2480 targets, for new executable.
2481 (libguile_la_SOURCES): Mention script.c.
2482 (modinclude_HEADERS): Add script.h.
2483 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2484 not dynamic linking is enabled. This is because we're generating
2485 executables now. Move CY_AC_WITH_THREADS call after those, so the
2486 values of cy_cv_threads_libs captures the libs chosen above.
2487 * Makefile.in, configure, aclocal.m4: Regenerated.
2489 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2490 We don't maintain this interface any more, and it just confuses
2493 * alloca.c: #include <scmconfig.h>, not <config.h>.
2494 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2495 it'll get included in disties.
2497 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2499 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2500 be distributed, because they confuse people.
2501 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2503 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>

2506 OpenBSD by default).
2507 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2508 * configure, scmconfig.h.in: Regenerated.
2510 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2512 * backtrace.c (scm_backtrace): Split message string across
2513 newlines properly. GCC is more tolerant of this than other
2516 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2518 Merge threads directory into libguile.
2519 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2520 threads.h: New source files.

2522 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2524 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2525 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2526 coop-threads.c.cygnus, coop-threads.h.cygnus.
2527 * configure.in: If we're using threads, include threads.o in
2529 * _scm.h, libguile.h: threads.h lives in this directory now.
2530 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2531 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2532 currently used, but brought along for information's sake.
2533 * ChangeLog-threads: log from old 'threads' directory.
2534 * Makefile.in, configure: Rebuilt.
2536 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2538 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2541 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2543 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2545 Merge GH interface library into libguile.
2546 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2547 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2548 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2549 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2551 (EXTRA_libguile_la_SOURCES): ... here.
2552 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2553 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2554 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2555 New variables, describing how to build the gh test programs.
2556 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2557 build the test programs, and we probably should have been linking
2558 libguile.la against them all along, to support AIX shared libs.
2559 Add cflags for threads to CFLAGS; add libs for threads to new
2560 variable THREAD_LIBS, used in Makefile.am.
2561 * ChangeLog-gh: log from old `gh' subdirectory.
2562 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2564 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2566 * acconfig.h: Undo change of Apr 9; including the definition of
2567 PACKAGE in the guile headers conflicts with applications' own
2569 * scmconfig.h.in: Regenerated.
2571 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

2578 when PROC is receiving no arguments.
2580 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2582 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2583 have S_IFSOCK. This is the case under Ultrix.
2585 * posix.c (scm_status_exit_val, scm_status_exit_val,
2586 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2587 Ultrix versions of WIFSTOPPED, etc., which assume that their
2588 arguments are lvalues (hmm).
2590 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2592 * eval.c: Doc fixes.
2594 * throw.c: Doc fixes; rearranged.
2596 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2598 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2600 * acconfig.h: Added entry for PACKAGE.
2601 * scmconfig.h.in: Regenerated.
2603 Changes to work with automake-1.1n, which has better libtool support.
2604 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2605 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2607 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2609 * Makefile.in: Rebuild.
2611 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2613 * stime.c (scm_mktime): take an optional zone argument.
2614 (scm_localtime): check putenv return value.
2615 (scm_strftime, scm_strptime): moved from posix.c. move #include
2617 stime.h, posix.h: update prototypes.
2618 (bdtime2c, setzone, restorezone): new static procedures.
2619 (scm_mktime, scm_strftime): use them.
2620 (scm_strftime): don't call mktime before strftime. Use
2621 filltime for return value.
2622 (filltime): convert NULL zname to #f.
2623 (scm_strptime): return a count of characters consumed, not
2624 the remaining string.
2626 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2628 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2629 (scm_mktime): likewise.
2631 Uncomment localtime and mktime.
2633 * configure.in: add AC_STRUCT_TIMEZONE.
2635 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2637 * stime.c (scm_init_stime): don't define ticks/sec.
2638 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2639 return value problem and is still portable.)
2641 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2643 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2644 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2645 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2646 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2647 cpp_err_symbols.c): Corresponding changes.
2648 * Makefile.in: Regenerated.
2650 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2652 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2653 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2654 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2655 * putenv.c: new file, from sh-utils 1.12.
2657 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2658 since allocation isn't for Scheme objects.
2659 (scm_putenv): copy strings before placing in the environment.
2661 * stime.c (scm_current_time): throw an error if time returns -1,
2662 instead of returning #f.
2663 (scm_get_internal_real_time, scm_get_internal_real_time): use
2664 scm_long2num for return value instead of SCM_MAKINUM.
2666 * stime.h: prototypes updated.
2668 * stime.c (scm_time_in_msec): apparently unused, deleted.
2670 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2672 * configure.in: check for gettimeofday.
2674 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2675 which may be more usefully portable than a gettimeofday interface.
2677 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2679 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2681 * Makefile.in: Regenerated.
2683 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2685 * stime.c (filltime): recovered static procedure.
2686 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2689 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2690 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2692 * posix.c (scm_mknod): split the mode argument into type and perms
2693 arguments, like the extra fields returned by stat.
2695 * fports.c (scm_pipob): set the close, free and print procedures.
2696 (scm_close_pipe): new procedure.
2698 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2699 define them in boot-9.scm
2701 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2703 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2704 wan't defined. Don't include fd.h.
2706 * Previously fd.h was regenerated whenever configure was run,
2707 forcing a couple of files to be recompiled.
2709 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2710 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2711 Check for _fileno as well as _file.
2713 * ioext.c: don't fd.h.
2714 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2717 * Change the stratigy for getting information about errno
2718 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2719 generating lists of symbols during the build process, which will
2720 not always work, include comprehensive lists in the distribution.
2721 To help keep the lists up to date, the "check_signals" and
2722 "check_errnos" make targets can be used.
2724 * configure.in: don't check for a command to extract errno codes.
2725 * Makefile.am: update file lists, remove errnos.list and errnos.c
2726 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2727 check_errnos targets.
2728 (CLEANFILES): remove errnos.c and errnos.list, add
2729 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2730 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2731 * errnos.default: deleted.
2732 * cpp_signal.c: new file.
2733 * cpp_errno.c: renamed from errnos_get.c.
2734 * cpp_err_symbols, cpp_sig_symbols: new files.
2735 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2736 * error.c (scm_init_error): #include cpp_err_symbols instead of
2738 * posix.c (scm_init_posix): don't intern signal symbols. #include
2741 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2743 * strop.c (scm_i_index): allow the lower bound to be equal to the
2744 length of the string, so a null string doesn't always give an error.
2746 * posix.h: new prototypes.
2747 * posix.c (scm_status_exit_val, scm_status_term_sig,
2748 scm_status_stop_sig): new functions, as in scsh. They break down
2749 process status values as returned by waitpid.
2751 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2753 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2754 configure doesn't know about it.
2756 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2758 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2760 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2761 which defines C variables with global linkage.
2763 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2765 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2768 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2770 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2771 has time to check why this doesn't work well with continuations.
2773 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2775 * Fix shell syntax error; some shells won't tolerate
2776 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2778 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2780 * posix.c (scm_uname): throw an error if uname fails instead
2783 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2785 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
2788 * async.c (scm_ints_disabled): definition moved from error.c.
2790 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2792 * acconfig.h: Removed PACKAGE.
2794 * scmconfig.h.in: Regenerated.
2796 * snarf.h: g++ says it's non-portable not to specify the first
2797 argument in a varargs declaration. I introduced the first
2798 argument by using preprocessor conditionals.
2800 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2802 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2803 (scm_freopen): use RO string macros for filename and modes.
2804 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
2806 * posix.c (scm_getgrgid): simplify conversion of name to C string.
2807 (scm_mknod): use RO string macros for path.
2809 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2810 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2812 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2813 use SCM_ROSTRINGP and SCM_ROCHARS.
2815 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2817 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2820 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
2821 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
2822 support for byte vectors.
2824 * print.c (scm_iprin1): Limit number of vector elements printed
2825 according to pstate->length.
2827 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2829 * backtrace.c (scm_display_error_message): don't segv if message
2832 * error.h: prototype for scm_error_scm.
2834 * error.c (scm_error_scm): new procedure, reimplements scm-error
2835 in C and uses scm_error.
2837 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2839 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2840 pointer to the Scheme variable read-hash-procedures and intern it
2841 in scm_init_read. Modify scm_read_hash_extend and
2842 scm_get_hash_procedure to use the pointer.
2844 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2846 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2847 (SCM_KEYWORD_STYLE): defined.
2849 * read.c (scm_read_opts): add a keywords option. This isn't a
2850 boolean option, in case someone wants to add support for DSSSL
2852 Setup scm_keyword_prefix symbol.
2853 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2855 I've left keyword support disabled by default, since it doesn't
2856 seem to break the module system and it gives R4RS standard behaviour.
2857 It can be reactivated with (read-set! keywords 'prefix).
2859 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2861 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2862 before constructing arbiter.
2864 * eval.c (scm_m_define): Bugfix: Check that the object is a
2865 closure before setting the procedure property!
2867 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2869 * ports.c: Removed `ungetc-char-ready?'.
2871 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2873 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2874 (idea from Mikael: make it a pair so scm_permanent object only
2876 (scm_read_hash_extend): don't call scm_permanent_object.
2877 (ideas from Mikael): if chr is already in the list, replace its
2878 procedure instead of appending it again. If proc is #f, remove
2880 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2882 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
2884 * gdbint.c (gdb_read): update scm_lreadr usage.
2886 * load.h: update prototypes.
2888 * load.c (scm_primitive_load, scm_read_and_eval_x,
2889 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
2891 * read.h: add prototype for scm_read_hash_extend. Change args for
2894 * read.c (scm_read_hash_procedures): new variable.
2895 (scm_read_hash_extend): new procedure.
2896 (scm_get_hash_procedure): new procedure.
2897 (scm_lreadr): use scm_get_hash_procedure instead of an argument
2898 for extended # processing.
2899 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
2900 scm_read_token): remove case_i, sharp arguments. Change callers.
2902 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
2904 * read.h (SCM_N_READ_OPTIONS): increase to 3.
2905 (SCM_CASE_INSENSITIVE_P): define.
2907 * read.c: add case-insensitive option to scm_read_opts.
2908 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
2909 to determine whether to convert symbol case.
2910 (default_case_i): definition removed.
2911 * read.c (scm_read_token): if case_i, downcase ic before doing
2914 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2916 * configure.in: Added configuration option `guile-debug'.
2917 Configure with --enable-guile-debug if you want a bunch of extra
2918 functions used for debugging when developing Guile.
2920 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
2922 * procs.c (make-cclo): New undocumented debugging procedure: Make
2923 compiled closure with internal procedure PROC and length LENGTH.
2924 Only compiled if GUILE_DEBUG is defined.
2926 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
2928 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
2930 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
2932 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
2933 with 3 or more args internally to the evaluator.
2935 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2937 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
2938 with 3 or more args internally to the evaluator. This is mainly
2939 because we don't want to pass entry and exit points of the
2940 debug support twice, but it also seems to increase the speed of
2941 the evaluator for such calls (e. g. (+ 1 2 3)).
2943 * backtrace.c (scm_display_application): New procedure:
2944 display-application; Set fancy printing parameters individually
2945 for different types of display (backtrace, error, application).
2946 (These should of course be customizable!)
2948 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
2949 clear the CHECK-flags.
2951 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2953 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
2955 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2957 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
2958 from pairs with a GLOC in the car.
2960 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
2961 otherwise `symbol-hash' will behave badly.
2962 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
2963 we get segmentation fault!
2965 * symbols.c: Added #include "weaks.h". New functions:
2966 `builtin-bindings' and `builtin-weak-bindings'. (These will be
2967 moved to an extraneous library when we split libguile.)
2969 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2971 * filesys.c (scm_stat): stat now takes fport arguments too as
2972 documented in the manual.
2974 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2976 * debug.c (scm_single_step): Bugfix: Call continuation with
2977 scm_call_continuation instead of throwing to it.
2979 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2981 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
2982 argument wasn't declared to be optional.
2984 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2986 * stime.c (scm_init_stime): Add feature "current-time".
2988 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2990 * throw.h: prototype for scm_exit_status.
2991 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
2992 args to derive an exit status. Allows (quit) to work from a
2994 (scm_exit_status): new function.
2997 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2999 * eval.c (scm_deval): Removed some old code.
3000 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3002 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3005 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3008 * procs.c: Introduce the existent C function scm_thunk_p at the
3009 Scheme level as well.
3011 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3013 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3014 used from C to easily lookup the value of a symbol in the current
3017 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3019 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3020 scm_init_unif in this file. This will also fix a previous problem
3023 * configure.in: Added AM_MAINTAINER_MODE
3025 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3027 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3030 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3032 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3033 source files that are not always included in libguile but should
3034 have their dependencies calculated by automake. This variable is
3035 recognized by automake, no further magic is needed.
3036 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3037 to deal exclusively with *.lo files, as it seems. The *.o files
3038 are built automatically when the corresponding *.lo file gets
3041 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3043 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3046 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3048 * unif.c (scm_array_set_x): minor change to argument error checking.
3050 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3052 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3053 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3054 They should only be included in the library at configure.in's
3056 (libguile_la_LDADD): Include the appropriate .lo files here.
3057 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3058 so we know when to build them (and their .lo bretheren).
3059 * configure.in (LIBLOBJS): New substituted variable. We let
3060 configure decide which .o files to include in LIBOBJS, and then
3061 put the corresponding list of .lo files in LIBLOBJS. The latter
3062 is what we pass to libtool.
3063 * Makefile.in, configure: regenerated.
3065 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3067 * symbols.c (scm_sysintern0): New function. Contains the core of
3068 old scm_sysintern but doesn't take a second value argument.
3069 (scm_sysintern): Now uses scm_sysintern0.
3070 (scm_sysintern_no_module_lookup): Renamed to
3071 scm_sysintern0_no_module_lookup and doesn't take a second value
3072 argument any longer.
3074 * symbols.h (scm_sysintern0: Added declaration.
3076 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3077 scm_sysintern when interning option keys. Otherwise we risk
3078 destroying the values of already interned variables.
3080 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3081 scheme-level boolean (use SCM_NFALSEP).
3083 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3085 (scm_backtrace): New function. (C version of old function from
3086 boot-9.scm) Motivation: Make it possible to display backtraces
3087 without depending on boot-9.scm. (I'm uncertain if this
3088 motivation is good enough...)
3090 * root.h (scm_root_state): Add member the_last_stack_var.
3091 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3093 * root.c (mark_root): Mark scm_the_last_stack_var.
3095 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3098 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3100 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3101 1. mark_lazy_catch didn't mark the smob.
3102 2. Both functions above have standard variants:
3103 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3104 free_lazy_catch --> scm_free0.
3106 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3108 * throw.c (scm_internal_lazy_catch): New function.
3109 (scm_lazy_catch): Rewritten to use it.
3110 (scm_ithrow): Handle the new lazy catch representation.
3111 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3112 that doesn't have a jmpbuf is a lazy catch clause.
3113 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3114 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3115 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3117 (scm_init_throw): Register the new lazy-catch smob type.
3118 * throw.h (scm_internal_lazy_catch): decl for new function.
3120 * throw.c (scm_internal_catch): Doc fixes.
3122 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3123 configure.in. Including this might cause problems if applications
3124 that link against libguile include their own copies of alloca, but
3125 if they're using autoconf, they should be adding libguile to LIBS
3126 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3127 the copy in libguile, and things will be okay. (I think.)
3129 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3131 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3133 strop.h: move prototypes too.
3135 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3137 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3140 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3141 etc. I deleted them from filesys.c long ago, but didn't
3142 notice they were here too (although ineffective since
3143 sys/stat.h wasn't included).
3145 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3147 * eval.c: Don't define alloca in GCC case. gcc will automatically
3148 use __builtin_alloca if appropriate.
3150 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3152 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3153 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3154 that values of automatic variables are preserved. See comments
3155 for safe_setjmp for details.
3157 Change from Thomas Morgan:
3158 * variable.c: Include eq.h.
3159 (var_equal): New function.
3160 (variable_smob): Use var_equal as the discriminator for variables.
3162 * throw.c (s_throw): Remove extraneous declaration.
3164 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3165 * eval.c: Add necessary CPP cruft to support that.
3166 * configure, Makefile.in, scmconfig.h.in: regenerated.
3168 Change from Thomas Morgan:
3169 * procprop.c (scm_procedure_properties): Convert the Scheme
3170 boolean returned by scm_procedure_p into a C boolean before using
3171 it as a condition for SCM_ASSERT.
3172 (scm_procedure_property): Likewise.
3174 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3175 indications of Unixness.
3178 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3180 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3182 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3184 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3185 "unknown # object" error messages.
3187 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3188 (scm_i_index) and declare it static. Add a 'direction' argument
3189 to indicate what way the search should go.
3190 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3192 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3193 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3195 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3197 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3199 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3200 to avoid clash with various scsh forks.
3202 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3204 The following two changes (ramap.c, throw.c) are motivated by the
3205 apparent unportability of forward declarations of static arrays of
3206 the form `static foo bar[];'.
3208 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3209 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3211 * throw.c (scm_throw): Moved above scm_ithrow.
3213 * options.h: Removed the extern declarations of scm_yes_sym and
3214 scm_no_sym since these are static.
3216 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3218 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3220 * Makefile.am: remove AWK=@AWK@.
3221 Add a rule for generating errnos.list.
3222 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3224 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3225 don't extract errnos, just set a variable (avoids the
3226 need to recompile error.c just because configure is run.)
3228 * unif.h: update prototypes.
3229 * unif.c (scm_uniform_array_read,write): change the offset and
3230 length arguments to start and end, for consistency.
3232 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3234 * ioext.h: update prototypes.
3235 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3236 scm_read_line_x, it's a more general procedure using an
3237 interface from scsh. read-line and read-line! are now defined
3239 Note that the new read-line trims the terminator
3240 by default, previously it was appended to the returned string. An
3241 optional argument specifies how to process the terminator (scsh
3242 compatible). For the old behaviour: (read-line port 'concat).
3243 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3244 returns a pair, but is converted to multiple values if the scsh
3247 socket.h: update prototypes.
3248 * socket.c (scm_recvfrom): for consistency with other procedures,
3249 take start and end as separate optional arguments.
3250 (scm_recv, scm_recvfrom): don't allow the second argument
3251 to be a size, only a buffer. Change the scheme names to
3252 recv! and recvfrom!. Don't return the buffer.
3254 * ioext.h, posix.h: move prototypes too.
3255 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3256 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3257 "read.h" and "unif.h".
3258 * ioext.c: include "chars.h"
3260 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3262 * dynl.c: The dynamic linking and module registration functions
3263 are now defined even when dynamic linking is not available for the
3264 host system. Some of their functionality can be done without
3265 dynamic linking; when it's really needed, they throw errors.
3267 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3269 * configure.in: Only define DYNAMIC_LINKING when one of the system
3270 dependent functions is detected.
3271 * dynl.c (scm_dynamic_func): New function to get the address of a
3272 function in a dynamic object.
3273 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3274 produced by scm_dynamic_func as the thing to call.
3276 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3278 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3279 (scm_register_module_xxx, scm_registered_modules,
3280 scm_clear_registered_modules): New functions.
3282 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3284 * symbols.c (scm_sysintern): Renamed to
3285 scm_sysintern_no_module_lookup.
3286 (scm_sysintern): New function to take the place of the old
3287 scm_sysintern. It uses the current toplevel lookup closure to give
3288 the symbol its value. This is a temporary hack to put packages
3289 like gtcltk into their own module.
3290 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3291 us whether `scm_top_level_lookup_closure_var' has been initialized
3293 * eval.c (scm_init_eval): Set it.
3295 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3297 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3298 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3300 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3302 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3303 scm_sys_dup): deleted: FD capability will be added to other
3305 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3306 scm_fd_free, fd_smob, scm_intern_fd.
3307 (scm_open): renamed from scm_sys_open. Return a port instead of
3308 an FD object. Make the mode argument optional.
3309 (scm_sys_create): deleted, it's just a special case of open.
3310 (scm_init_filesys): move interning of constants O_CREAT etc.,
3311 here (were previously using SCM_CONST_LONG macro).
3312 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3314 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3315 include "fports.h" and <stdio.h>
3316 (scm_stat, scm_select): don't support FD objects.
3318 * error.h: adjust scm_syserror_msg prototype.
3319 * error.c (scm_syserror_msg): take an extra argument for errno.
3320 Using the global value didn't always work, since it could be
3321 reset by procedure calls in the message or args arguments.
3323 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3324 I don't understand why the check was there (and what about the
3327 * strop.c (scm_string_copy): allow shared substrings to be copied.
3329 * unif.h: corresponding change to prototypes.
3330 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3331 recognize two new optional arguments: offset and length. Allow
3332 the port argument to be an integer (file descriptor, for scsh).
3333 Include <unistd.h> for "read" prototype.
3335 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3337 * socket.c: don't include filesys.h.
3339 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3341 * Makefile.am: add AWK=@AWK@ (?)
3343 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3345 Add a rule to generate errnos.c from errnos.
3346 * error.c (scm_init_error): include errnos.c.
3347 * errnos_cnvt.awk: new file, converts the list of errno codes to
3349 * errnos_get.c: new file.
3350 * errnos.default: new file, contains errnos to try if they can't
3351 be extracted from errno.h.
3352 * configure.in: if using GCC, try and extract errno codes from
3356 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3358 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3359 * Makefile.am: Made libguile into a libtool library.
3360 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3361 Set libtool_libs to indicate that libguile is a libtool library.
3362 See guile/ChangeLog for details.
3363 * .cvsignore: ignore "*.lo", the libtool library objects.
3365 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3367 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3368 use htons in getservbyport argument.
3370 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3372 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3373 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3376 * objprop.c (scm_object_property): No need to take the CDR of the
3377 value returned by scm_object_properties, since Aug 20 change.
3379 * configure.in: When checking for struct linger, #include
3380 <sys/types.h> as well as <sys/socket.h>. I've never known
3381 <sys/types.h> to cause any portability problems, and Solaris's
3382 <sys/socket.h> needs it.
3383 * configure: Rebuilt.
3385 I think the Sun compiler has chosen a perverse way to interpret
3386 ANSI declarations combined with K&R definitions. We'll
3387 appease it a little bit. But when it invades France, we fight.
3388 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3389 * print.h (scm_iprlist): Here too.
3390 * numbers.c (scm_divbigdig): Change definition to match
3391 declaration in numbers.h.
3392 * unif.c (scm_makflo): Change definition to match declaration in
3395 * init.c (scm_boot_guile): Don't return the value of
3396 scm_boot_guile_1. This function doesn't return a value;
3397 scm_boot_guile_1 doesn't return a value (or return at all).
3399 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3402 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3403 compile. I have a feeling this function is a bad idea anyway ---
3404 one should always test for features, not systems.
3406 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3407 semicolons. Only pure luck kept this from being noticed earlier.
3409 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3411 * socket.c (scm_recvfrom): Added missing semicolon.
3413 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3415 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3416 the buffer and start and end positions for scsh networking
3419 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3421 * configure.in: Revert previous change to this file; the problem
3422 is due to transient automake weirdness.
3423 * configure: Rebuilt.
3425 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3426 PLUGIN/guile.libs. configure generates the latter from the former.
3427 * Makefile.in: Rebuilt.
3429 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3430 need this if we install scripts, like guile-snarf.
3431 * configure: Rebuilt.
3433 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3435 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3437 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3439 * socket.c (scm_addr_vector): fix faulty scm_listify.
3441 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3443 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3444 style block comment is no longer considered an error.
3446 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3448 * PLUGIN/guile.libs.in: New file.
3449 * PLUGIN/guile.libs: Removed from repository.
3450 * configure.in: Create PLUGIN/guile.libs from
3451 PLUGIN/guile.libs.in. This is for including additonal libraries
3452 needed for dynamic linking.
3453 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3454 instead of PLUGIN/guile.libs.
3456 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3458 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3460 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3461 occurrences of the given element from the list, not just the
3462 first. This is how the Emacs Lisp functions behave, how the
3463 analogous Common Lisp functions behave, and (I believe) how the
3464 older Maclisp functions worked. I realize that this change may
3465 break code, but it seemed better to break it before the Guile
3468 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3469 Their prototypes were already present in gc.h, but they weren't
3471 (scm_init_storage): Initialize scm_protects.
3472 * root.c (scm_protects): New element of scm_sys_protects.
3474 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3476 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3478 * libguile.h: Added #include "libguile/net_db.h".
3480 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3481 30 change. That file is only meant for communication between the
3482 configuration process and load.c. If code linked against libguile
3483 wants to get at the paths mentioned in libpath.h, it can call
3484 functions declared in load.h.
3486 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3488 * libguile.h: Removed #include "libguile/fdsocket.h"
3490 * net_db.c: Added #include <sys/socket.h>.
3492 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3494 * filesys.c (scm_input_waiting_p): use select in preference to
3495 FIONREAD, since the latter doesn't detect EOF.
3496 Throw error if neither select nor FIONREAD available.
3498 * socket.c (scm_connect): take a port, not a fd object.
3499 (scm_fill_sockaddr): throw an error if fam is not recognised.
3500 (scm_bind): use scm_fill_sockaddr.
3501 (scm_listen): take a port, not a fd object.
3502 (scm_accept): take and return a port. return #f in the car if
3503 address can't be got
3504 (scm_sock_fd_to_port): new procedure.
3505 (scm_socket): use scm_sock_fd_to_port.
3506 (scm_addr_vector): throw error if unrecognised address type.
3507 take an extra argument with the calling procedure name.
3508 (scm_getsockname): take a port. return #f if address can't be got.
3509 (scm_getpeername): take a port. return #f if address can't be got.
3510 (scm_recvfrom): take a port. return #f for address component if can't
3512 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3513 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3515 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3517 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3518 use separate data pointers, to allow them to be designed
3519 independently and reused.
3520 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3521 Renamed from catch_body, catch_handler, and uncaught_throw; made
3523 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3525 (scm_catch): Use the above.
3526 (scm_throw): Don't bother printing a message for an uncaught
3527 throw; we establish a default handler in init.
3528 * throw.h (scm_internal_catch): Prototype updated.
3529 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3531 (struct scm_body_thunk_data): New structure, used as data
3532 argument to scm_body_thunk.
3533 * init.c (struct main_func_closure): New structure, packaging up
3534 the data to pass to the user's main function.
3535 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3536 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3537 scm_internal_catch to establish a catch-all handler, using
3538 scm_handle_by_message. This replaces the special-case code in
3540 (invoke_main_func): Body function for scm_internal_catch; invoke
3541 the user's main function, using the main_func_closure pointer to
3542 decide what to pass it.
3543 * root.c (struct cwdr_body_data): Remove handler_proc member.
3544 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3545 (cwdr_handler): Removed.
3547 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3549 * socket.h (SCM_P): update bind prototype.
3550 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3551 include "feature.h".
3552 (scm_socket): return a port, not a file descriptor object.
3553 include "fports.h" and <unistd.h>
3554 (scm_bind): take a port, not a file descriptor object.
3555 take an extra argument for address args.
3557 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3558 INADDR_NONE, INADDR_LOOPBACK.
3560 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3562 * init.c: include net_db.h and not fdsocket.h.
3563 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3565 * Makefile.am: corresponding changes.
3566 * socket.h: renamed from fdsocket.h, fix names.
3567 * net_db.h: renamed from socket.h, fix names.
3568 * socket.c: renamed from fdsocket.c.
3569 remove _sys from procedure names.
3570 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3571 add "socket" to features list.
3572 * net_db.c: renamed from socket.c.
3573 remove _sys from procedure names.
3574 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3575 add "net-db" to features list.
3576 include "net_db.h". don't include <sys/socket.h> or
3579 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3581 * tags.h (scm_tags): Removed comma at end of last enumerator.
3583 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3585 Don't use GCC extensions to allocate space for debugging frames.
3586 (Here he goes again! Why do we put up with this?!)
3587 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3588 an scm_debug_info structure, not an in-line array of them. Add
3589 'info' member, to say how many vect elements we've used, for eval
3591 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3592 a new variable debug_info_end to mark the end of vect, instead of
3593 the address of the 'info' pointer itself.
3594 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3595 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3596 (SCM_APPLY): Explicitly allocate space for debug.vect.
3597 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3598 * stacks.c: Adjusted for new debug frame structure.
3599 (RELOC_INFO, RELOC_FRAME): New macros.
3600 (stack_depth, read_frames): Use them, and new scm_debug_frame
3601 element 'info', instead of magically knowing that eval frames have
3602 an info pointer sitting after vect.
3603 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3605 (scm_init_stacks): Formatting tweaks.
3607 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3609 Give GCC more control flow information, so it can be sure that
3610 variables aren't used uninitialized.
3611 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3612 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3613 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3614 scm_misc_error): Tell GCC that these functions never return.
3615 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3616 out the field type, call abort if SCM_ASSERT returns, to placate
3618 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3619 scm_wta ever returns. We can't handle this case anyway, and this
3620 gives the optimizer more information.
3621 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3622 scm_wta ever returns.
3624 In some cases, the code is fine, but GCC isn't smart enough to
3625 figure that out; this usually happens when one variable is only
3626 initialized and used when a particular condition holds true, and
3627 we know that condition will never change within a given invocation
3628 of the function. In this case, we simply initialize the variables
3629 to placate the compiler, hopefully to a value which will cause a
3630 crash if it is ever actually used.
3631 * print.c (scm_iprin1): Initialize mw_pos.
3632 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3633 * throw.c (scm_ithrow): Initialize dynpair.
3634 * unif.c (scm_uniform_vector_ref): Initialize cra.
3635 * struct.c (init_struct): Initialize prot.
3636 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3638 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3639 if EXPR contains no expressions.
3641 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3643 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3644 cause an infinite loop (???). So much for the algebraic
3645 equivalency of variable-sized arrays and alloca...
3647 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3649 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3650 a SCM boolean, not a C boolean.
3652 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3654 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3655 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3656 rules for raising scm_mtrigger. Previously, unfortunate but not
3657 unlikely circumstances could result in almost constant invokation
3658 of the gc. Now, this situations should be less likely, but they
3659 are not prevented completely.
3661 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3663 * numbers.c (scm_fuck): Procedure removed; looks like old test
3665 * numbers.h: Prototype removed.
3667 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3669 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3670 array to a pointer, to match my Nov 21 change in eval.c.
3672 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3674 * libguile.h: Added #include "libguile/backtrace.h", #include
3675 "libguile/stacks.h".
3677 * strings.c (scm_string scm_make_string scm_string_ref
3678 scm_string_set_x scm_string_equal_p scm_string_append):
3679 Bugfix according to scm patch from Aubrey Jaffer:
3680 Corrected long-standing
3681 (not (eqv? (integer->char 128)
3682 (string-ref (make-string 1 (integer->char 128)) 0)))
3683 bug found by John Kozak <jk@noontide.demon.co.uk>.
3685 * strports.c, strports.h: Make scm_eval_0str return the value of
3686 the last expression evaluated (previously, it returned void).
3688 * strports.c, strports.h: New function: scm_read_0str. Does what
3691 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3693 * simpos.c (scm_getenv): return #f if string can't be found in the
3694 environment instead of throwing an exception, for compatibility
3695 with numerous other systems.
3697 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3699 * Makefile.am (.c.x): Use guile-snarf.
3700 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3702 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3704 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3706 * backtrace.c (scm_display_error_message): Made non-static, and
3707 renamed from display_error_message.
3708 * backtrace.h (scm_display_error_message): Added extern decl.
3709 * throw.c (uncaught_throw): Use it to display the error message.
3711 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3713 * inet_aton.c: Use #if 0, not #ifdef 0.
3715 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3717 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3718 to convert the returned value.
3719 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3720 the offset argument.
3722 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3724 Add new interface to catch/throw, usable from C as well as
3726 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3727 (scm_internal_catch): New function, replaces...
3728 (scm_catch_apply): Deleted.
3729 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3730 mechanism which is a bit more code, but can be used nicely from C
3731 and implement the Scheme semantics as well.
3732 (scm_internal_catch): This is the replacement; it's named after
3733 the analogous function in Emacs.
3734 (scm_catch): Reimplemented in terms of the above.
3735 (struct catch_body_data, catch_body, catch_handler): New
3736 functions, used by scm_catch.
3737 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3738 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3739 support for new cwdr.
3741 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3744 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3746 * acconfig.h: Added DYNAMIC_LINKING symbol.
3747 * configure.in: Add option and checks for dynamic linking.
3748 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3749 dynl.h: New files for dynamic linking support.
3750 * Makefile.am (libguile_a_SOURCES):
3752 (modinclude_HEADERS): Added "dynl.h".
3753 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3755 * init.c (scm_boot_guile_1): Call
3756 scm_init_dynamic_linking to initialize dynamic linking support.
3758 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3760 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3761 (as we Schemers say). It needs to be global, so that I can tweak
3762 it for the proper operation of unexec.
3763 (scm_boot_guile_1_live): New variable, see above.
3765 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3767 * guile-snarf.sh: Removed.
3768 * PLUGIN/guile.libs: Added dependency for -lm.
3769 * acinclude.m4: Renamed from aclocal.m4.
3770 * PLUGIN/greet: Removed.
3771 * Makefile.am, aclocal.m4: New files.
3772 * configure.in: Updated for Automake.
3774 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3776 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3777 and not top_level_lookup_thunk_var.
3779 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3781 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3783 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3785 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3786 Scheme function, instead of syntax. Single argument is now a
3789 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3791 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3792 scm_ra_divide): Properly terminate statements passed as arguments
3793 to IVDEP macros. (Thanks to Bernard Urban.)
3795 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3796 with non-constant sizes. (Thanks to Bernard Urban.)
3798 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3800 It's an "eval closure", not an "eval thunk." A thunk is a
3801 function of no arguments.
3802 * root.h (struct scm_root_state): Renamed
3803 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3804 (scm_top_level_lookup_closure_var): Renamed from
3805 scm_top_level_lookup_thunk_var.
3806 * root.c (mark_root): Uses changed.
3807 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3808 * init.c (scm_start_stack): Uses changed.
3809 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3810 Change scheme-visible name to *top-level-lookup-closure* from
3811 *top-level-lookup-thunk*.
3813 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3815 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3816 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3818 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3820 * gc.c (struct scm_heap_seg_data): Doc fixes.
3822 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3823 sweeping. Then, prepend each segment's free cells to its
3824 freelist, rather than wiping out the old value. (Thanks to Marius
3827 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3828 scm_check_freelist, scm_debug_newcell): New functions and
3829 variables, for debugging freelist problems.
3830 * pairs.h (SCM_NEWCELL): New debugging version added.
3831 * gc.h (scm_debug_newcell): Added extern declaration, used by
3832 debugging version of SCM_NEWCELL.
3834 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3836 On some systems <libc.h> conflicts with <unistd.h>, and should not
3837 be #included at all.
3838 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3839 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3840 * configure.in: Call it.
3841 * posix.c, filesys.c: Use its results to decide whether or not to
3843 * configure, scmconfig.h.in: Rebuilt with autoconf and
3846 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3848 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3849 pointer to the stdio stream before calling scm_setbuf0, so the
3850 latter will be able to retrieve it. I'm surprised this didn't
3851 segfault earlier. (Thanks to Christopher Lee.)
3853 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3855 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3858 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3860 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3861 number of stack narrowing specifier pairs. The first specifier in
3862 a pair controls inner border, the second the outer border. A
3863 number means cut that number of frames, a procedure object means
3864 cut until that object is found in operator position in a frame.
3866 * root.c (cwdr): Bugfix.
3868 * read.c: Recording of positions disabled by default.
3870 * procs.c (scm_closure_p): New function.
3872 * posix.c (scm_tmpnam): New function.
3874 * load.c: Added #include "throw.h".
3875 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3878 * load.c, load.h (scm_read_and_eval_x): New function.
3880 * eval.c: Renamed debug option "deval" to "debug".
3882 (scm_eval_x): `eval!' is no longer accessible from the scheme
3883 level. Motivation: We can't allow operations which introduce
3884 glocs into the scheme level. Guile's type system can't handle
3885 these as data. Use `eval' or `read-and-eval!' as replacement.
3887 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
3888 SCM_CONSP since this is a macro!; Set vframe.prev to
3889 scm_last_debug_frame instead of 0. In this way we can look
3890 "above" the virtual start stack frame if we wish.
3891 (scm_debug_hang): New function: Useful for debugging Guile in
3892 certain tricky situations. Will probably be removed later...
3894 * debug.h: Changed semantics of debug option "backtrace". This
3895 option now only indicates whether we want automatic backtrace at
3898 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3900 * ports.c: #include "filesys.h"
3901 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
3903 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
3904 Motivation: This is system specific code which is related to file
3905 I/O. It also may use select. Added code by Gary Houston to
3906 detect presence of character in stdio buffers.
3908 * libguile.h: #include "libguile/libpath.h"
3910 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
3911 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
3912 SCM_SITE_DIR; Install libpath.h among the other include files.
3914 * load.c, load.h (scm_sys_package_data_dir): New function.
3916 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3918 * stacks.h: Bugfix: Don't use tail-array length field as stack
3919 length field! This screwed GC.
3921 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3923 * _scm.h: Added #ifndef around definition of macros min and max.
3925 * __scm.h: Added hooks for threads to plugin to in ints protection
3926 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
3927 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
3928 the main code in these macros duplicated and spread over multiple
3929 files. Renamed SCM_THREADS_SWITCHING_CODE ->
3930 SCM_THREAD_SWITCHING_CODE.
3932 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
3934 * snarf.h: New file.
3935 * guile-snarf.sh: New file.
3936 * Makefile.in (inner_h_files): Added snarf.h
3937 (ancillary, install, uninstall, distclean): Added actions for
3939 (.c.x): Use guile-snarf.
3940 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
3941 (gen_c_files): Note that these depend on guile-snarf.
3942 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
3943 now in "snarf.h". Added #include "snarf.h" to get them.
3944 * libguile.h: Added #include "snarf.h".
3945 (Patches applied and tweaked by Jim Blandy.)
3947 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3949 * socket.c: Use K&R style declaration for 'close'; the GNU coding
3950 standards suggest against providing prototypes for system
3951 functions. Thanks to Greg Troxel.
3953 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3955 * strports.c (scm_eval_0str): New function.
3956 #include "read.h", to get prototype for scm_read.
3957 * Makefile.in (strports.o): Update dependencies.
3958 * strports.h: New prototype.
3960 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
3961 scheme name from "int?" to "integer?". It seems to do the job.
3962 * numbers.h: Rename prototype too.
3963 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
3966 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
3967 scm_num_eq_p): Rename these according to R4RS conventions: call
3968 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
3969 to making libguile R4RS compliant without ice-9...
3971 * load.c (scm_sys_search_load_path): Search for files under all
3972 extensions listed in the %load-extensions variable. If FILENAME
3973 is absolute, return it unchanged, without searching the load path.
3974 (scm_loc_load_extensions): New variable, pointing to
3975 %load-extensions' value cell.
3976 (scm_init_load): Initialize it, and the value it points to.
3977 (scm_primitive_load_path): Improve error reporting.
3979 * load.c (scm_loc_load_hook): New variable, pointing to value cell
3980 of new Scheme variable %load-hook.
3981 (scm_primitive_load): Apply %load-hook to filename.
3983 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
3985 * configure.in: add tests for figuring out whether buffered data
3986 is available in a FILE structure, which is needed by char-ready.
3988 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
3991 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
3992 exceptions using misc_error instead of syserror. It seems a bit
3993 odd to throw an exception if a string can't be found in the
3994 environment, but it's consistent with open-file, stat etc.
3995 (simpos.h): remove sys_ from getenv.
3997 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
3998 occurs, throw an error instead of returning errno. Return value
4000 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4002 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4004 * filesys.c (scm_stat2scm): derive file type and permissions from
4005 the stat mode and append them to the returned vector.
4006 There isn't much overhead in doing this and it avoids the need to
4007 work with S_IRUSR et al. in Scheme.
4008 Define symbols scm_sym_regular etc.
4009 (scm_init_filesys): don't intern S_IRUSR etc.
4011 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4012 and s_primitive_load_path.
4014 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4016 * error.h: don't declare error symbols. prototype for scm_misc_error.
4018 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4021 * error.c: use SCM_SYMBOL to set up error keys.
4022 scm_misc_error: new procedure.
4024 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4026 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4027 between `#!' and `!#' is ignored.
4028 (skip_scsh_block_comment): New function.
4030 * feature.c (scm_set_program_arguments): New argument, FIRST.
4031 * feature.h: Update prototype.
4032 * init.c (scm_boot_guile_1): Pass new argument to
4033 scm_set_program_arguments.
4035 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4037 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4038 (scm_boot_guile): Call scm_set_program_arguments here, later than
4039 the old initialization.
4041 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4042 initialization procedure.
4043 - Delete in, out, err arguments; there are other perfectly good
4044 ways to override these when desired.
4045 - Delete result argument; this function shouldn't ever return.
4046 - Rename init_func argument to main_func, for less confusion.
4047 - Delete boot_cmd argument; main_func is more general.
4048 -Add 'closure' argument, to help people pass data to main_func
4049 without resorting to global variables.
4050 - Abort if reentered; don't bother returning an error code.
4051 - Call scm_init_standard_ports to set up the default/current
4052 standard ports; no need to pass them to scm_start_stack.
4053 - Remove code to evaluate the boot_cmd, and start the repl; let
4054 the user do something like that in main_func if they want.
4055 - Remove code to package up a return value; main_func can do any
4057 - Call exit (0), instead of returning.
4058 (scm_start_stack): Don't initialize the I/O ports here; that's
4059 weird. Delete in, out, err arguments. Move guts to
4060 scm_init_standard_ports, scm_stdio_to_port.
4061 (scm_init_standard_ports): New function, to set up current and
4062 default standard ports.
4063 (scm_start_stack, scm_restart_stack): Make these static.
4064 * init.h (scm_boot_guile): Adjust declaration.
4065 (scm_start_stack, scm_restart_stack): Remove externally
4066 visible declarations for these.
4067 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4069 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4070 written out several times in scm_start_stack.
4071 * fports.h: New declaration for the above.
4073 * feature.c (scm_set_program_arguments): New function.
4074 * feature.h: New declaration for the above.
4076 * ports.c: Formatting tweak.
4078 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4080 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4081 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4082 for obtaining the address of a car or cdr field. Motivation:
4083 &SCM_CXR make assumptions about the internal structure of the
4086 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4087 Motivation: see SCM_CXRLOC.
4089 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4090 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4091 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4092 Motivation: Safer use. Some other macros are defined in terms of
4093 these operations. If these are defined using the SCM_SETCXR
4094 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4095 to inefficiency and an <e1> with side-effects could potentially
4096 break. Also, these particular operations are heavily utilized in
4097 the garbage collector. In unoptimized code there will be a
4100 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4101 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4102 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4103 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4104 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4105 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4106 vports.c: Cleaned up use of pairs: Don't make any special
4107 assumptions about the internal structure of selectors and
4108 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4109 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4110 (Among other things, this change makes it easier to build Guile
4111 with certain compilers which have problems with casted lvalues.)
4113 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4115 * stacks.c: Improve selection of relevant stack frames when making
4116 a stack object. Introduce one level of indirection in the stack
4117 object to make it possible to "narrow" to a certain region of the
4118 stack. This facilitates making use of more clever algorithms (not
4119 implemented) for selecting relevant frames and gives a cleaner
4120 design since selection of frames can be done independently of
4121 extraction of frames from the real stack.
4122 (scm_stack_id): Also take #t as argument which means look at
4125 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4126 Turn n_tail into an integer directly representing current number
4127 of frames in stack. Add field tail.
4129 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4131 * debug.c (scm_make_memoized): Made it available at scheme level.
4132 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4133 SCM_NIMP before applying heavier predicates in argument checking.
4134 (scm_local_eval): Also take memoized object as argument.
4136 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4137 aren't created with zero length, but should such a strange
4138 creature suddenly turn up...
4140 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4142 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4143 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4145 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4147 * variable.c (scm_make_variable): Make the name hint optional, as
4149 (anonymous_variable_sym): Renamed from variable_sym. All uses
4152 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4153 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4154 of scm_primitive_load_path was also changed to
4155 "primitive-load-path", from "%try-load-path". Callers changed.
4156 We'd like to respect the convention that a function named
4157 "try-mumble" should behave just like the function called "mumble",
4158 but return #f instead of signalling some error.
4159 * load.h: Rename prototypes.
4161 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4163 * print.c (make_print_state, grow_print_state), print.h: Modified
4164 the print state representation: Don't use a tail array for
4165 recording of circular references. Resizing of the print state
4166 structure invalidates the print state pointer. To avoid passing
4167 around an indirect print state reference to all printing
4168 functions, we instead let the print state reference a resizable
4171 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4173 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4174 Don't crash when passed an improper list terminated by a
4175 non-immediate value.
4177 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4179 Allocate data for structures on an eight-byte boundary, as
4180 required by the tagging system.
4181 * struct.c (alloc_struct): New function.
4182 (scm_make_struct, scm_make_vtable_vtable): Call it.
4183 * struct.h (scm_struct_n_extra_words): Bump to 3.
4184 (scm_struct_i_ptr): New "field".
4185 * gc.c (scm_gc_sweep): When we need to free the data, use the
4186 information stored by alloc_struct to find the beginning of the
4187 block allocated to the structure, so we can free it.
4189 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4191 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4194 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4195 (scm_debug_info): New member: id.
4197 * stacks.c: Stacks are now represented as structs; Stacks have an
4198 id given to them by `start-stack'.
4199 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4201 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4202 Changed stack representation.
4204 * debug.c (scm_procedure_name): Try procedure property `name' for
4205 compiled closures aswell.
4207 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4209 * eval.c: scm_i_name moved to gsubr.c
4210 (scm_m_define): Record names of all kinds of procedure
4211 objects. (Earlier, only closures were recorded.)
4213 * procprop.h: Added declaration of scm_i_name.
4215 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4216 (scm_make_gsubr): Record names of compiled closures.
4218 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4220 * debug.c, debug.h: Removed obsolete code.
4222 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4223 stacks.c: Renamed regs --> scm_contregs.
4225 * print.c (scm_free_print_state): Cleanup print state before
4226 returning it to pool. It is better to do it here than in
4227 scm_prin1 since scm_prin1 is called often.
4229 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4230 s_set_source_property_x): Check that first argument is a pair or a
4233 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4234 scm_i_line, scm_i_column and scm_i_breakpoint global.
4236 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4237 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4240 * debug.h: Added debug object smob declaration and macro
4243 * configure.in: Build with backtrace.o and stacks.o if debug
4246 * Makefile.in: Added entries for new files: backtrace.c,
4247 backtrace.h, stacks.c and stacks.h.
4249 * symbols.c (scm_sym2ovcell): Fixed documentation.
4251 * _scm.h (min, max): Added.
4253 * async.c: Moved `min' macro to _scm.h.
4255 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4256 SCM_BACKTRACE_INDENT.
4258 * eval.c: Added new debug options `maxdepth' and `indent'.
4260 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4262 * print.h: Added selector SCM_PRINT_STATE.
4264 * print.c: New functions: scm_make_print_state,
4265 scm_free_print_state.
4267 * print.h: Added declarations for scm_make_print_state,
4268 scm_free_print_state.
4270 * debug.c (scm_m_start_stack): New acro.
4272 * debug.h: Small cleanup.
4274 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4277 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4302 More prototype-related changes from Marius Vollmer:
4303 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4304 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4305 * ports.h (ptobfuns): Added prototypes. This means some casting in
4307 * fports.c: Added casts for initializations, since the functions
4308 are defined to take FILE * as their stream argument, not SCM.
4309 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4310 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4311 to `char *str_data' to conform to prototype.
4313 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4315 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4317 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4319 * stime.c, stime.h: use SCM_P method.
4321 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4323 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4324 be given at least two arguments. Insist that lst's last element
4325 be a list, but don't make any requirements of its predecessors.
4327 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4329 * eval.c (scm_nconc2last): Revert last change; there seems to be
4330 other stuff going on here.
4332 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4334 * eval.c (scm_nconc2last): Make sure that each element of lst
4335 (which is a list of argument lists, except for the tail) is a
4336 proper list, i.e., finite and terminated by '().
4338 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4340 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4343 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4344 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4347 * vectors.c (scm_make_vector): Fill vectors with the undefined
4348 value, to help make Guile Scheme code more portable to other
4351 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4352 * symbols.h, tags.h: Doc fixes.
4354 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4356 * async.c (scm_take_signal): Doc fixes.
4358 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4360 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4361 want to subtract it from the modulus; we just want to leave it
4364 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4366 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4369 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4371 * throw.c (scm_catch_apply): Finished implementation of
4374 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4376 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4378 (scm_init_filesys): set "i/o-extensions" feature.
4381 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4383 * Makefile.in (root.o): Correct dependencies.
4385 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4387 * Makefile.in: Added dependency entry for root.o.
4389 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4390 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4392 * init.c (scm_start_stack): Set initial root continuation number
4395 * procs.c: New function: scm_thunk_p.
4397 * procs.h: Added declarations of scm_thunk_p.
4399 * root.c: Renamed `call-with-new-root' -->
4400 `call-with-dynamic-root'.
4401 (cwdr): Removed allocation of new root state. This should be done
4402 separately by use of scm_make_root.
4403 (scm_apply_with_dynamic_root): New function: Does what it
4404 sounds like. Needed when spawning threads.
4406 * root.h: Added member last_debug_frame to root state.
4407 Added #include "libguile/debug.h"
4409 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4410 arguments. The motivation is that code in root.c needs catch
4411 functionality, and we want to avoid code duplication.
4412 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4413 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4414 handlers that run without popping the stack into the dynwind
4417 * throw.h: Added prototypes for scm_catch_apply and
4420 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4422 * root.h (scm_root, scm_set_root): Decouple thread support details
4423 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4424 SCM_SET_THREAD_LOCAL_DATA.
4426 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4427 and tortoise scanning loop.
4429 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4431 * Makefile.in: Rebuild dependencies.
4433 * libguile.h: #include "libguile/print.h" before "smob.h", since
4434 the latter uses the print_state structure.
4436 * throw.c (scm_ithrow): Use the correct variable when checking to
4437 see if a given element of scm_dynwinds is a valid catch.
4439 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4440 structure, abort; don't just silently ignore the garbage.
4442 * _scm.h: #include "print.h" here, since it seems to be used just
4444 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4445 strports.c, unif.h: Don't #include "print.h".
4447 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4449 * feature.h (scm_loc_features): Removed external declaration.
4450 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4452 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4454 * feature.c (scm_init_feature): Added threads feature (needs to be
4455 initialized here, since features doesn't exist when
4456 scm_init_threads is called).
4458 * libguile.h: Added #include "libguile/../threads/threads.h".
4459 (This is a kludge to get thread support working. This should be
4462 * configure.in, acconfig.h: Added flags for thread support.
4464 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4467 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4468 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4471 * _scm.h: Added conditional #include "threads.h"
4473 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4474 SCM_THREADS_SWITCHING_CODE.
4476 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4477 allocate the basic dynamic root object.
4478 (scm_boot_guile): Added call to scm_init_root.
4480 * root.c, root.h: Added root smob.
4481 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4482 functions: Implements dynamic roots mostly according to spec in
4483 SCM manual. Main difference is that the second argument is a
4484 throw handler rather than an error "thunk".
4486 * root.h: Added declaration of scm_init_root.
4488 * root.c: Added #include "genio.h", #include "smob.h", #include
4489 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4491 (scm_init_root): Added #include "root.x".
4493 * throw.c: Added #include "stackchk.h"
4494 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4495 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4496 can be used in scm_call_with_new_root; Added reenabling of stack
4497 checking when catching a throw.
4499 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4501 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4503 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4504 element is not found, as per R4RS.
4506 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4508 * list.c: Doc fixes throughout.
4510 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4512 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4513 declare the char * to be const. Avoids a warning in rgx.c.
4515 * ports.h: spelling fix.
4517 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4520 * load.c (scm_sys_try_load_path): throw an error if file not found
4521 (like it says it in NEWS).
4523 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4525 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4526 PROPS slot to '(), not #f; it's an empty alist.
4528 * throw.h, throw.c: Use SCM_P instead of #if hair.
4530 Remove special support for uncaught throws; see throw.c for
4532 * throw.c (uncaught_throw): New function.
4533 (scm_ithrow): Call uncaught_throw if we don't find a throw
4534 target; don't mess with scm_bad_throw_vcell.
4535 (scm_bad_throw_vcell): Variable deleted.
4536 (scm_init_throw): Don't initialize it.
4538 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4541 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4543 * numbers.c (scm_istr2int): If the number is short (as most
4544 numbers are), just call scm_small_istr2int to deal with it.
4545 (scm_small_istr2int): New function, created by un-#ifdefing the
4546 non-bignum version of scm_istr2int and renaming it.
4548 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4550 * load.c (scm_sys_try_load): don't check whether value returned
4551 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4552 Change the Scheme name from %try-load to primitive-load.
4554 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4555 Can avoid passing a message, allowing it to be derived in the
4556 error handler (e.g., if we want to throw to the key both from
4559 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4561 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4562 references now have a new appearance which is more compact and
4563 also gives a clue about what the target of the reference is.
4564 By setting parameters in the print state, more fancy printing can
4565 be achieved. This is used by the (not yet commited) backtrace
4568 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4570 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4573 * print.c: Added #include "struct.h". Removed function
4576 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4577 scm_iprin1. Removed prototype for scm_prlist.
4579 * arbiters.c (prinarb),
4580 async.c (print_async),
4581 debug.c (prindebugobj, prinmemoized),
4582 eval.c (prinprom, prinmacro),
4583 filesys.c (scm_fd_print, scm_dir_print),
4585 mallocs.c (prinmalloc),
4586 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4587 smob.h (scm_smobfuns),
4588 srcprop.c (prinsrcprops),
4590 unif.c, unif.h (scm_raprin1, rapr1),
4591 variable.c (prin_var): Changed argument `int writing' to
4592 `scm_print_state *pstate'.
4594 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4595 that it will be called before scm_init_print.
4597 * print.c (scm_prin1): Print states are now allocated when calling
4598 scm_prin1 and then passed around to all printing functions as an
4599 argument. A cache `print_state_pool' enables reuse of print
4601 (scm_make_print_state): New function.
4602 (scm_iprin1): Adaption to print states.
4603 (scm_iprlist): An initial "hare and tortoise" scan brings down
4604 time complexity to O (depth * N). (Better time complexity will be
4605 achieved when the printing code is completely rewritten.)
4607 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4609 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4610 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4611 it gets done whether or not the cache variable has a value.
4613 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4615 Distinguish #f and ().
4616 * __scm.h: #undef SICP.
4617 * pairs.h (SCM_EOL): Delete this definition, equating it with
4619 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4620 the value it used to have. Doc fixes, too.
4622 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4624 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4625 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4626 Lord's implementation of structs, allowing for tail arrays as
4627 described in the manual. Also fixed some bugs. (Both the interface
4628 and the implementation should be improved.)
4630 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4632 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4633 People who whish to see the source can do `(print-enable 'source)'.
4634 Removed #ifdef DEBUG_EXTENSIONS.
4636 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4638 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4639 integer (assuming for now accepting an integer is a good thing).
4641 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4642 %S will be used instead for write'ing arguments.
4644 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4645 asserts. fix a few other asserts.
4646 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4647 scm_uniform_vector_ref, scm_array_set_x,
4648 scm_dimensions_to_unform_array): change args in
4649 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4650 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4651 scm_substring_fill_x): likewise.
4652 gsubr.c (scm_gsubr_apply): likewise.
4653 eval.c (SCM_APPLY): likewise.
4655 * eval.c (4 places): replace scm_everr with lgh_error or
4658 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4659 scm_memory_error): new procedures.
4660 scm_everr: deleted. can use scm_wta, dropping first two args.
4661 scm_error: convert NULL subr to SCM_BOOL_F.
4663 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4666 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4669 * error.c, error.h: new error keys: scm_arg_type_key,
4670 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4672 scm_wta: reimplement using lgh_error instead of scm_everr.
4674 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4676 * gdbint.c: scm_lread now has one more argument.
4678 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4679 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4680 loading source from non-file ports, which, e. g., happens when
4681 using the Emacs interface).
4683 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4686 * read.c: Added code for recording of positions of source code
4687 expressions; New functions: recsexpr, scm_lreadrecparen;
4688 _scm_make_srcprops --> scm_make_srcprops
4689 (scm_flush_ws): Removed updating of positions counters. This work
4690 is already done by scm_gen_getc
4692 * read.h: Added prototype for scm_lreadrecparen
4694 * print.c: Added #include "alist.h"
4696 * eval.c: Added #include "hash.h"
4698 * eq.c: Added #include "ramap.h"
4700 * options.c: Documentation fixes.
4702 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4703 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4704 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4705 --> scm_make_srcprops
4707 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4708 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4709 function calls in the definition of the whash access macros.
4711 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4713 * init.c (scm_boot_guile): Add level of indirection to
4714 scm_boot_guile_1() to ensure that stack base pointer is properly
4715 initialized. There was no guarantee that variable i was the
4716 highest/lowest variable on stack (i.e. the call frame of
4717 scm_boot_guile was not completely protected from gc).
4719 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4721 * ports.h (scm_port_table): put back file_name, it will be used to
4722 support debugging. Undo related changes in fports.c, ioext.c,
4725 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4727 * ports.h (scm_port_table): remove file_name member for now, it seems
4729 * fports.c (scm_open_file): don't set file_name in PTAB.
4730 (prinfport): don't use file_name in PTAB.
4731 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4732 * ports.c (scm_add_to_port_table): don't intialize file_name.
4733 (scm_port_file_name): remove for now.
4734 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4736 * fports.h (scm_mkfile): prototype deleted.
4737 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4739 * debug.c, unif.c: use scm_out_of_range instead of
4740 wta for range errors (ASSERT still needs work).
4742 * error.c, error.h (scm_out_of_range): new procedure.
4744 * error.c, error.h (scm_out_of_range_key): new key.
4746 * posix.c (scm_sync): #else was missing.
4748 * error.c, error.h: append _key to names scm_num_overflow and
4751 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4752 of consing an empty list.
4753 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4754 of macros, saves code and string space.
4755 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4756 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4757 lower case. Rename scm_syserror_m to scm_syserror_msg.
4758 error.h: prototypes for new procedures.
4760 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4762 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4764 * error.c, error.h: setup scm_num_overflow key.
4766 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4767 Remove definition of SCM_OVSCM_FLOW.
4769 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4771 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4772 explicit message and args.
4774 * error.c, error.h, __scm.h: change system_error_sym to
4777 * error.c (system_error_sym): remove leading %% from the Scheme name
4780 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4782 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4784 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4785 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4786 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4787 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4788 renamed. (These were introduced by unsupervised name
4791 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4793 * print.c: Added code for detection of circular references during
4794 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4795 a hook for printing of closures (accessible via print options).
4796 This leads to a split of calls to scm_iprin1 into two classes:
4797 elementary print operations (e. g. the code which prints a smob)
4798 still use scm_iprin1 while top level calls (like scm_display) use
4799 scm_prin1. scm_prin1 begins by clearing the data structure used
4800 to record reference information.
4802 * print.h: Added declarations of scm_prin1 and scm_prlist.
4804 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4806 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4808 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4810 * error.c (err_head): scm_iprin1 --> scm_prin1
4812 * debug.c: Adjusted header comment.
4816 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4818 * strerror.c: Doc fix.
4820 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4822 * gdbint.c (gdb_read): Now possible to run during GC.
4823 (unmark_port, remark_port): New functions.
4825 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4827 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4828 of allocating a new string object. Also, increase size by
4829 the factor 2 instead of 1.5.
4831 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4833 * __scm.h (SCM_P): Corrected to run under traditional C.
4835 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4838 * async.c: Calls to scm_sysintern corrected.
4840 * async.h (scm_async_clock): Redundant declaration removed.
4842 * continuations.c (scm_dynthrow): Redundant declaration removed.
4844 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4845 Definition typos corrected.
4847 * debug.h: Missing declarations of functions in debug.c added
4850 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4851 Missing declarations to functions in eval.c added.
4853 * filesys.c: Possibly uninitialized variable rv.
4855 * gc.h (scm_object_addr, scm_unhash_name): Missing
4856 declarations of functions defined in gc.c added.
4858 * genio.c: Possible typos str_data -> wstr_data. ???
4860 * genio.c: Possibly unintended shadowing of local variable
4861 `int c' (gotos out of scope of inner `c'). ???
4863 * init.c: Uninitialized `SCM last' may be used.
4865 * ioext.h: (scm_sys_isatty_p): Typo.
4867 * list.h (scm_list_head): Missing prototype for function in
4870 * numbers.c (scm_two_doubles): Changed from extern to static
4871 (is used only within numbers.c).
4873 * numbers.h: Repeated declarations removed.
4875 * ports.h (scm_close_all_ports_except): Declaration for the
4876 function defined in ports.c added.
4878 * posix.h: Missing declarations added.
4880 * procs.h (scm_make_subr_opt): Missing declaration added.
4882 * socket.h (scm_sys_gethost): Missing declaration added.
4884 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4886 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
4887 Missing declarations added.
4889 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
4891 * struct.c: Uninitialized variable `SCM answer' may be used.
4893 * unif.c (l2ra): Declaration prototype.
4895 * unif.c (scm_array_equal_p): Dummy definition removed (it is
4896 defined in ramap.c).
4898 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
4899 Redundant declarations removed (they are in ramap.h).
4901 * variable.h (scm_make_udvariable,
4902 scm_make_undefined_variable): Declaration corrected to
4903 correspond variable.c.
4905 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
4906 Missing declarations added.
4908 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
4910 * Makefile.in (distclean): Don't forget to delete fd.h.
4912 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4914 * fd.h.in, tags.h: Trivial cleanups.
4916 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
4917 marksweep.h just declared functions from gc.c.
4918 * gc.h, libguile.h: Don't #include "marksweep.h".
4919 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4920 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
4921 dependencies updated.
4923 * libguile.h: Don't #include "files.h"; it's been deleted.
4925 * files.c (scm_sys_delete_file): Moved to filesys.c.
4926 File is now empty; deleted.
4928 * filesys.c: scm_sys_delete_file is now here. Remove
4929 #if's; they seem to rely on remnants of an old portability
4930 regimen. If the problems come up again, solve them properly,
4931 using autoconf. Specifically: Don't test M_SYSV, and #define
4932 remove to be unlink if it's #defined; don't use remove just
4933 because HAVE_STDC_HEADERS is #defined.
4934 * filesys.h: Add declarations for scm_sys_delete_file.
4935 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4936 files.o, files.h, files.c, and files.x.
4937 * init.c: Don't #include "files.h", and don't call scm_init_files.
4939 Use SCM_P instead of PROTO; the latter intrudes on the user's
4941 * params.h: Deleted; definition of SCM_P moved to...
4942 * __scm.h: ... here, where it replaces PROTO macro.
4943 * libguile.h, smob.h: Don't #include "params.h".
4944 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
4945 smob.h: Fix prototypes accordingly.
4946 * Makefile.in: Update dependencies.
4947 (inner_h_files): Remove params.h.
4949 * gc.c: #include "gc.h"; every module should include its header,
4950 to let the compiler cross-check the declarations against the
4953 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
4954 simpos.h: #include "libguile/__scm.h".
4956 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
4958 * init.c: Don't forget to #include smob.h and init.h.
4959 * Makefile.in: Dependencies updated.
4961 * smob.h: Use PROTO instead of #if __STDC__.
4963 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
4965 * __scm.h: Doc fixes.
4967 * __scm.h, libguile.h: Use "quotes" in the #includes, not
4968 <angles>; this allows `make depends' to work properly.
4970 * libguile.h: #include smob.h and pairs.h before the others; they
4971 define typedefs used by other headers.
4973 C files should #include only the header files they need, not
4974 libguile.h (which #includes all the header files); the pointless
4975 recompilation was wasting my time.
4976 * Makefile.in (all .o dependency lists): Regenerated.
4977 * libguile.h: Don't try to get a definition for size_t here...
4978 * __scm.h: Do it here.
4979 * _scm.h: Since this is the internal libguile header, put things
4980 here that all (or a majority) of the libguile files will want.
4981 Don't #include <libguile.h> here; that generates dependencies on
4982 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
4983 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
4984 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5081 * weaks.c: Get "weaks.h".
5083 * stackchk.h: #include "libguile/debug.h",
5085 * print.h, read.h: #include "options.h", since everyone who uses
5086 either of these files will need that.
5088 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5089 anyone who uses this file will need them to define the smob
5090 printing functions. Also, get markers.h, since people will need
5091 to #define the mark functions.
5093 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5094 * ports.h: ... to here.
5096 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5097 don't rely on archaic C default type rules.
5099 * fports.h: #include "libguile/ports.h", since you need that in
5100 order to parse this.
5102 * genio.h: #include "libguile/print.h", because you need that to
5103 parse this; don't bother #including "ports.h", since print.h gets
5106 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5108 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5109 this; it's now a reference to an element of *scm_root.
5111 * debug.h: Don't #include "options.h"; the compiler won't be able
5112 to find that once the headers are installed; instead, #include
5113 "libguile/options.h".
5114 * gc.h: Same, with marksweep.h.
5115 * mbstrings.h: Same, with symbols.h.
5116 * scmhob.h: Same, with _scm.h.
5117 * smob.h: Same, with params.h.
5119 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5120 C files; there's no need for this, and it forces recompilations
5123 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5125 * error.c (scm_error): declare scm_error_callback.
5127 * error.h: prototype for scm_error_callback.
5129 * __scm.h: define lgh_error.
5130 (SCM_SYSERROR): redefine using lgh_error.
5132 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5134 * error.c (scm_error): new procedure.
5136 * error.h: prototype for scm_error.
5138 * Makefile.in (install): install scmconfig.h from the current
5139 directory, not $(srcdir).
5141 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5143 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5144 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5145 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5146 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,

5150 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5151 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5152 vports.h, weaks.h: #include "libguile/__scm.h", not
5153 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5154 dependencies are within libguile properly.
5156 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5158 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5159 when scmconfig.h doesn't exist.
5161 * load.c (scm_sys_try_load): Correct spelling.
5163 * feature.c (scm_loc_features): Make this static.
5165 * Makefile.in (libpath.h): Omit trailing slash from path. We
5166 shouldn't require it of users, so why put it here?
5168 Move code to initialize and search %load-path from ice-9 to C
5169 code, so we can use the load-path to find the ice-9 boot code;
5170 this makes it easier to run Guile without installing it. See
5171 corresponding changes in guile/Makefile.in.
5172 * feature.c: Move stuff concerned with the load path to load.c.
5173 (scm_compiled_library_path): Deleted.
5174 Don't #include libpath.h here.
5175 * feature.h: Don't mention scm_compiled_library_path.
5176 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5177 <sys/stat.h>, and <unistd.h> (if present).
5178 (R_OK): #define if the system hasn't deigned to.
5179 (scm_loc_load_path): New variable.
5180 (scm_init_load_path, scm_sys_search_load_path,
5181 scm_sys_try_load_path): New functions.
5182 (scm_init_load): Initialize scm_loc_load_path to point to the
5183 value cell of the Scheme %load-path variable.
5184 * load.h: Add declarations for scm_sys_search_load_path,
5185 scm_sys_try_load_path.
5186 * init.c: Call scm_init_load_path.
5187 * Makefile.in (feature.o, load.o): Dependencies updated.
5189 * load.c, load.h: Rewrite using PROTO macro.
5191 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5193 * gc.c (scm_cellp): New function: C predicate to determine if an
5194 SCM value can be regarded as a pointer to a cell on the heap.
5196 * gc.h: Added declaration of scm_cellp.
5198 * gdb_interface.h: New file: The GDB interface header from the GDB
5201 * gdbint.c: New file: GDB interface.
5203 * gdbint.h: New file: GDB interface.
5205 * libguile.h: Added #include <libguile/gdbint.h>.
5207 * init.c (scm_boot_guile): Added scm_init_gdbint.
5209 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5210 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5211 found if object files and source are kept separate).
5213 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5215 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5217 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5219 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5220 TK_SRC_DIR; they're not relevant any more.
5222 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5223 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5225 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5227 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5228 search path, so we can find the <libguile/MUMBLE.h> headers.
5230 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5232 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5233 implicit in the .c.o rule.
5234 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5237 Put the library path in a header file, instead of passing it on
5238 the command line in every compilation.
5239 * Makefile.in (libpath.h): New target.
5240 (feature.o): Depend on libpath.h.
5241 (clean): Delete libpath.h.
5242 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5243 * feature.c: ... #include "libpath.h" here.
5244 * .cvsignore: Ignore libpath.h.
5246 Don't install the unwashed masses of Guile header files in the
5247 main #include path; put most of them in a subdirectory called
5248 'libguile'. This avoids naming conflicts between Guile header
5249 files and system header files (of which there were a few).
5250 * Makefile.in (pkgincludedir): Deleted.
5251 (innerincludedir): New variable; this and $(includedir) are enough.
5252 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5253 (installed_h_files): Divide this up. Now this variable lists
5254 those header files which should go into $(includedir) (i.e. appear
5255 directly in the #include path), and ...
5256 (inner_h_files): ... this new variable says which files appear in
5257 a subdirectory, and are referred to as <libguile/mumble.h>.
5258 (h_files): List them both.
5259 (install): Create innerincludedir, not pkgincludedir. Put
5260 the installed_h_files and inner_h_files in their proper places.
5261 (uninstall): Corresponding changes.
5262 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5263 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5264 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5265 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5266 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5267 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5268 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5269 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5270 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5271 vports.h, weaks.h: Find __scm.h in its new location.
5272 * __scm.h: Find scmconfig.h and tags.h in their new locations
5273 (they're both "inner" files).
5275 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5277 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5279 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5281 * posix.c: Doc fixes.
5283 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5285 * socket.c: Don't include a prototype for inet_aton; just use a
5286 K&R style declaration, to avoid warnings but minimize the chance
5287 of conflicts with the system.
5289 On NextStep, <utime.h> doesn't define struct utime, unless we
5290 #define _POSIX_SOURCE before #including it.
5291 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5292 * acconfig.h: New comment text for above CPP symbol.
5293 * configure.in: Call it.
5294 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5296 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5298 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5299 testing for __EMX__.
5301 * posix.c: #include <libc.h>, if it exists.
5303 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5304 don't even know if the latter exists.
5306 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5307 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5308 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5310 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5312 (scm_init_posix): Use them when initializing the Scheme constants
5315 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5317 * Makefile.in (libdir, includedir, bindir): Use the
5318 autoconf-supplied values, instead of deriving them ourselves.
5319 (pkgincludedir, datadir, pkgdatadir): New variables.
5320 (install, uninstall): Put the header files in a special
5321 subdirectory, not in the main search path.
5323 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5324 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5326 * Makefile.in (IMPLPATH): Deleted; never used.
5328 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5329 on the Tcl/Tk source any more.
5330 (INCLUDE_CFLAGS): Remove references to the above.
5332 * Makefile.in (version.o): Corrected dependencies.
5334 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5336 * libguile.h: #include "version.h"
5338 * init.c (scm_boot_guile): Call scm_init_version.
5339 * gscm.c (gscm_run_scm): Call scm_init_version.
5341 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5342 GUILE_VERSION): AC_DEFINE these.
5343 (acconfig.h): #undef the above symbols.
5345 * Makefile.in (libobjs): Add version.o.
5346 (installed_h_files): Add version.h.
5347 (c_files): Add version.c.
5348 (gen_c_files): Add version.x.
5349 (version.o): New rule.
5350 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5351 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5352 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5353 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5354 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5355 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5356 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5357 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5358 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5359 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5360 weaks.o): Add version.h to dependency lists.
5361 (markers.o): Remove duplicate rule.
5363 * version.h: New file.
5365 * version.c: New file.
5367 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5369 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5370 array; use it appropriately. Since GCC is quite happy to
5371 subscript functions, it never warned us about this; we should use
5372 -Wpointer-arith in the future. I guess we never tested
5375 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5377 * socket.c: Doc and copyright fixes.
5379 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5381 * debug.c: Fixed and improved gdb support.
5383 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5385 * socket.c: Added declaration of inet_aton to avoid compiler
5386 warning. (Hope this solution is correct.)
5388 * stime.c: Added declaration of ftime. (This is missing in
5391 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5393 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5395 * Makefile.in (c_files): add strerror.c.
5397 * strerror.c: new file from Emacs' sysdep.c.
5398 maybe configure should also check for sys_errlist.
5400 * configure.in (AC_REPLACE_FUNCS): add strerror.
5402 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5404 * debug.c (scm_init_debug): Added initialization for
5405 scm_evaluator_traps.
5407 * debug.h, debug.c: Various name changes.
5408 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5409 "debug-options-interface". See commentary in options.c.
5411 * options.h, options.c: Options now have documentation strings.
5412 Also added a long explanatory commentary.
5414 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5417 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5418 last_debug_info_frame is now updated in all cases.
5420 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5423 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5425 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5426 Added option STACK_CHECKING.
5428 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5430 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5432 * __scm.h: Removed symbols for debugging support.
5434 * acconfig.h: Added symbols for debugging support.
5436 * configure.in: Added user option for debugging support.
5437 --enable-debug will include the debugging code into libguile.a.
5439 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5440 scm_relocate_chunk_to_heap.
5442 * debug.c: New file: low-level debugging support. It also
5443 includes support for debugging with gdb. (The extensions to gdb
5444 are written by Per Bothner at Cygnus.)
5446 * debug.h: New file: low-level debugging support.
5448 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5449 argument pairs. Extensive modifications to the debugging
5450 evaluator. Added "SECTION:" commentaries to clarify what happens
5451 when, during double compilation. Renamed EVALIMP --> EVALIM.
5452 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5453 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5454 the beginning of the file. New procedure: scm_unmemocopy.
5455 Added some global state variables needed by the debugging
5456 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5457 check_entry, check_apply, check_exit, debug_options and
5458 evaluator_traps. New acro: undefine.
5460 * eval.h: Renamed EVAL --> XEVAL.
5462 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5463 --> scm_make_weak_key_hash_table.
5465 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5466 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5468 * libguile.h: Conditionally include debug.h
5470 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5471 scm_object_properties shouldn't return handle. `handle' now gets
5472 initialized in scm_set_object_properties_x. scm_object_properties
5473 doesn't any longer create an entry in scm_object_whash.
5475 * options.c: New file: handling of run time options.
5477 * options.h: New file: handling of run time options.
5479 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5481 * print.c: New procedure: scm_print_options
5483 * print.h: Defines for print options.
5485 * read.c: New procedure: scm_read_options
5487 * read.h: Defines for reader options.
5489 * root.h: Added scm_source_whash among scm_sys_protects.
5491 * srcprop.c: New file: source properties.
5493 * srcprop.h: New file: source properties.
5495 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5496 (Bug found by A. Green.)
5498 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5500 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5502 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5504 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5506 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5507 and should be called by the final client.
5509 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5511 * gc.h: Use the PROTO macro when declaring functions.
5512 * gc.c: Use the PROTO macro when declaring static functions.
5513 Remove the CPP hair around function definitions.
5515 * gc.c (scm_init_storage): Initialize scm_asyncs.
5517 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5518 preprocessor symbol; "__scm.h" is where it might get #defined.
5519 * __scm.h: Similar: #include <scmconfig.h> before testing
5522 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5524 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5526 * init.c (scm_boot_guile): Add init_func argument; call
5527 (*init_func) instead of calling scm_appinit; it's ucky to
5528 hard-code names for the user's procedures.
5529 * init.h (scm_boot_guile): Adjust declaration.
5531 * __scm.h (PROTO): New macro, for declaring functions with
5534 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5535 eliminate all the __STDC__ conditionals.
5536 (scm_boot_guile): Add declaration.
5537 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5538 Remove __STDC__ conditionals around function definitions; the
5539 declarations in init.h will provide the same information, more
5542 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5543 complain about it in the error message; the error message is
5544 adequate without that note, and there's nothing the user can do
5547 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5549 * Makefile.in (ancillary): Drop def.sed.
5551 * posix.c (scm_init_posix): Use numeric values, rather than
5552 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5553 F_OK. The symbols aren't available on some systems, and I'm
5554 pretty sure their values are fixed by common widespread practice.
5555 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5557 More functions unavailable on some systems.
5558 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5559 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5561 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5562 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5563 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5564 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5565 stub that signals an error as the #else.
5567 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5569 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5571 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5573 * unif.c: include ramap.h.
5575 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5577 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5579 * ports.c: include sys/ioctl.h.
5581 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5583 * configure.in: check for sys/ioctl.h.
5585 * ports.c: include <malloc.h> not "malloc.h".
5587 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5589 * fports.c: remove ttyname and tmpnam declarations.
5591 * posix.c: fewer ttyname declarations.
5593 * fports.c: include <string.h> not "string.h".
5595 * init.c, ioext.c: include string.h and unistd.h.
5597 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5599 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5600 genio.c, simpos.c, vports.c: include string.h.
5602 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5604 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5606 (scm_addr_buffer_size): change type from scm_sizet to int.
5607 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5608 from scm_sizet to int.
5610 * error.c: include unistd.h.
5612 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5615 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5617 * __scm.hd, def.sed: deleted.
5619 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5621 Changes for NeXT, suggested by Robert Brown.
5622 * configure.in: Call AC_TYPE_MODE_T.
5623 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5624 NeXT. Put header file list in alphabetical order.
5625 * configure, scmconfig.h.in: Regenerated.
5626 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5628 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5631 * acconfig.h: New file, providing documentation for the CPP
5632 symbols defined in configure.in
5633 * acconfig-1.5.h: Removed; superceded by the above.
5635 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5637 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5639 * fports.c (scm_open_file): don't return #f, throw error.
5641 * ioext.c (fileno): renamed from %fileno.
5642 (soft-fileno): deleted.
5644 * ports.c (scm_port_revealed): don't need to check for -1 from
5646 (scm_set_port_revealed_x): return unspecified, not #f.
5648 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5650 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5652 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5654 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5656 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5658 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5659 This is necessary on Ultrix, and doesn't hurt portability.
5661 * Makefile.in (dist-dir): New target, implementing a new dist system.
5662 (installed_h_files): Put in alphabetical order.
5663 Remove duplicate entries for markers.h and unif.h.
5664 (c_files): Remove duplicate entries for markers.c.
5665 (ancillary): Renamed from anillery; all uses changed. Remove
5666 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5667 Remove all the ../doc/* files; doc/Makefile.in handles that.
5669 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5671 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5672 every if must have an else, or else the whole command has a
5673 non-zero exit code whenever the if's condition is false.
5675 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
5677 * posix.c: include string.h.
5679 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
5681 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
5684 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
5685 Remove leading % from scheme names.
5686 Do not return error values, call SCM_SYSERROR or similar.
5688 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
5690 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
5692 * struct.c (scm_init_struct): new file.
5694 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
5696 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
5697 (scm_list_head): added list-head for rapidly chopping argument
5698 lists off of longer lists (and similar).
5700 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
5702 * objprop.c (scm_object_property): assq the cdr of the whash
5703 handle for obj, not the handle itself.
5705 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
5707 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
5708 weak hash tables last of all marking to avoid an obscure gc bug.
5709 WARNING: circular lists stored in a weak hash table will hose us.
5711 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
5713 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
5714 new functions similar to scm_substring_move_left_x and
5715 scm_substring_move_right_x.
5717 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
5719 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
5722 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
5724 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
5726 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
5728 * strports.c (scm_strprint_obj): convenience function. C for
5729 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
5731 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
5732 removed to a separate library
5734 * init.c (scm_boot_guile): copied from guile-tcl.c.
5735 Initialization specific to tcl interpreters removed.
5737 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
5739 * ports.c (scm_ports_prehistory): size malloced here doesn't
5740 matter so long as it is non-0 (got rid of "* 4").
5742 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5744 * gscm.h: gscm_mkarray eliminated (presumably was not being used
5745 since its definition was bogus).
5747 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
5749 * mallocs.[ch]: back again (for rx at least).
5751 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5753 * ports.c: removed functions relating to the mapping between ports
5754 and descriptors. (That stuff is unix-specific and should be collected
5755 in a separate library).
5757 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
5758 (Tom Mckay@avanticorp.com)
5760 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
5762 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5763 handled correctly (SCM_FREEP was applied to them) -- test for
5764 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
5765 being overwritten with #f. (brown@grettir.bibliotech.com)
5767 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
5769 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
5770 for a specific symbol or for all symbols.
5772 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
5774 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
5775 keys and weak values confused).
5777 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
5779 * list.c (scm_last_pair): map '()=>'()
5781 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
5783 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
5784 Generalized assoc and hash-table functions.
5785 Factored pairs.c into multiple files.
5787 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
5789 * gscm.c (gscm_run_scm): got rid of objprop.
5791 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
