1 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3 * posix.c (scm_getpwuid): If we can't find an entry, return our
4 own message, instead of using scm_syserror --- the getpwMUMBLE
5 functions don't set `errno' to anything interesting.
7 1998-10-03 <jimb@savonarola.red-bean.com>
9 Get rid of warnings from the cooperative threading system.
10 * threads.h (scm_single_thread_p, scm_yield,

15 * coop-defs.h (coop_next_runnable_thread,
16 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
17 Prototypes for these here, even though they're from iselect.c.
18 (coop_condition_variable_wait, coop_join): Add prototypes.
19 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
20 scm_threads_free_condvar): Make these smob functions static.
21 * coop-threads.h (coop_init): Give this a real prototype.
22 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
23 (coop_next_runnable_thread): No need to provide prototype; it's in
26 * scmconfig.h.in: .detarenegeR
28 * iselect.c, threads.c: Doc fixes.
30 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
32 * Makefile.in: Regenerated with a patched automake, to get
33 dependency generation right when using EGCS.
35 * inet_aton.c (inet_aton): Add prototype, to remove compiler
36 warning. (Thanks to Robert Pluim.)
38 * inet_aton.c (inet_aton): Reassure the compiler that the
39 arguments to the <ctype.h> macros are all unsigned characters, not
42 1998-10-03 <jimb@savonarola.red-bean.com>
44 Getting rid of more warnings...
45 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
46 today's change to ../configure.in.
47 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
48 * scmconfig.h.in: Regenertaded.de.,.__
49 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
50 (scm_localtime, scm_mktime): Use a const char * to manipulate the
53 * readline.c: Doc fix.
54 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
55 * readline.h (scm_filename_completion_function): Add prototype.
56 (scm_init_readline): Make this into a prototype.
58 * readline.c (scm_filename_completion_function): Use SCM_PROC to
59 declare this, instead of calling scm_make_subr manually.
61 1998-10-02 <jimb@savonarola.red-bean.com>
63 * readline.h (scm_init_readline): Add prototype for this.
64 (scm_init_readline): Make this a real prototype.
66 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
68 Warning fixes from Maciej Stachowiak:
69 * backtrace.h (scm_display_application, scm_backtrace): Add
71 * debug.c (scm_m_start_stack): Make this function static.
72 * fluids.h (scm_fluid_p): Add prototype.

79 * stacks.h (scm_stack_id): Add external prototype.
80 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
82 1998-09-30 Mark Galassi <rosalia@cygnus.com>
84 * gh.h: took out the definitions of vset and vref, since they are
85 replaced by the proper vector routines that correspond to the R4RS
88 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
90 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
91 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
92 third argument, a C expression that should result in a SCM value,
93 which is used to initialize the variable. Reimplemented
94 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
97 * version.h (scm_libguile_config_stamp): Add prototype.
98 (From Maciej Stachowiak.)
100 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
102 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
103 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
105 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
107 * print.c (scm_iprin1): Rather than having one i, and using it in
108 several places, declare a fresh i local to each block where it is
109 used, and give it a signedness appropriate to its use in each case.
112 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
115 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
116 signed/unsigned clashes.
118 * posix.h (scm_tmpnam): Added prototype.
120 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
121 scm_make_subclass_object): Add external prototypes.
123 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
124 comparison is okay here.
126 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
128 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
129 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
131 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
134 * load.c (swap_port): Make this function static.
136 * load.c (scm_search_path): Make max_path_len and max_ext_len
137 unsigned, since they're compared against string sizes.
139 * load.c (init_build_info): Make i unsigned.
141 * ioext.h (scm_read_line): Add prototype.
143 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
144 scm_hash_fn_remove_x): Make hash bucket index local variable k
145 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
146 accurately as possible.
148 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
149 comparisons, and range checking to make sure those casts are
152 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
153 signed/unsigned comparisons.
155 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
156 avoid signed/unsigned comparisons.
157 * smob.h (scm_numsmob): Change extern declaration to match.
159 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
160 avoid signed/unsigned comparisons.
161 * ports.h (scm_numptob): Change extern declaration to match.
162 (scm_current_load_port, scm_set_port_line_x,
163 scm_set_port_column_x): New prototypes.
165 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
166 test code, and it causes warnings.
168 * gh.h (gh_int2scmb, gh_uniform_vector_length,
169 gh_uniform_vector_ref): Added prototypes.
171 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
172 debugging support unconditionally. That's backtrace.c, stack.c,
173 debug.c, and srcprop.c.
174 (EXTRA_libguile_la_SOURCES): Omit those from here.
175 * Makefile.in: Regenerated.
177 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
179 * options.c (scm_options): Bugfix: Allow empty list of options!
181 * debug.c, debug.h (scm_single_step): Removed.
182 (scm_with_traps): New procedure. This procedure could easily be
183 written in Scheme but needs to be highly optimized.
185 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
187 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
188 Check SCM_TRAPS_P before trapping.
190 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
192 Changes to avoid signed/unsigned comparison warnings.
193 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
194 (scm_gc_sweep): Make n and j local to the blocks they're used in,
195 so they can have appropriate types for each application. Make i
196 signed. Use initializers in some spots. I'll probably pay for
198 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
199 (scm_must_realloc): Make nm unsigned.
200 (init_heap_seg): Make new_seg_index and n_new_objects signed.
201 (scm_init_storage): Use prototype-style definition, and make the
203 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
204 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
206 * filesys.c (scm_readlink): Make local vars rv and size ints, to
207 avoid signed/unsigned comparison warnings, and because the return
208 value of readlink may be -1. Don't bother casting the third
209 argument to readlink.
211 * filesys.c (scm_dirname, scm_basename): Move these to their own
212 page, at the end of the file.
213 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
215 * eval.h (scm_eval_options_interface): Add external prototype for this.
216 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
218 * eval.c (scm_lookupcar1): Make this static.
220 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
221 Make these prototype declarations, not K&R-style.
223 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
224 unsigned comparison warning.
226 * appinit.c: File removed. It had a single function in it, empty,
227 whose reason for existence is explained in no documentation or
228 comment. I think it's there as a default for some Tcl-style
229 initialization, but Tcl abandoned that approach a while ago.
230 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
231 (BUILT_SOURCES): Remove appinit.x.
232 * Makefile.in: Regenerated.
234 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
236 * Makefile.in: Regenerated using the last public version of
237 automake, not the hacked Cygnus version.
239 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
241 Remove Totoro kludge.
242 * Makefile.in, scmconfig.h.in: Regenerated.
243 * init.c, readline.c: Don't check if TOTORO is #defined.
245 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
247 * Makefile.am: Adjust for new thread configuration system.
248 (INCLUDES): Include the value of THREAD_CPPFLAGS.
249 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
251 (THREAD_LIBS): Definition deleted; automake will generate such
252 things automatically.
253 * Makefile.in: Regenerated.
255 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
257 Simplify smob and port marking; set the mark bit in the generic
258 marking code, and make marker routines only responsible for
259 turning up outgoing pointers.
260 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
261 before calling the marking function. Don't call the marking
262 function if it's zero.
263 * markers.c (scm_mark0): Just return #f. This function isn't
264 necessary at all now, but it's harmless to call it. We'll leave
265 it in so other folks' code doesn't croak at link time.
266 (scm_markcdr): Don't call SCM_SETGC8MARK.
267 * async.c (mark_async): Don't call SCM_SETGC8MARK.
268 * dynl.c (mark_dynl_obj): Same.
269 * root.c (mark_root): Same.
270 * srcprop.c (marksrcprops): Same.
271 * unif.c (markra): Same.
272 * variable.c (scm_markvar): Same.
273 * ports.c (scm_markstream): Same.
274 (void_port_ptob): Specify zero for our marking function.
275 * debug.c (debugobjsmob): Same.
276 * dynwind.c (guardsmob): Same.
277 * filesys.c (dir_smob): Same.
278 * fluids.c (fluid_smob): Same.
279 * fports.c (scm_fptob, scm_pipob): Same.
280 * mallocs.c (mallocsmob): Same.
281 * regex-posix.c (regex_t_smob): Same.
282 * smob.c (freecell, flob, bigob): Same.
283 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
284 * throw.c (jbsmob, lazy_catch_funs): Same.
286 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
288 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
289 scm_copy_tree on code in order not to let memoized code to leak
290 out. Thus, scm_copy_tree needs to copy vectors as well since
291 quasiquote can introduce evaluated code also inside vector
294 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
296 * eval.c (scm_copy_tree): Removed ability to copy vectors.
298 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
299 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
302 * unif.c: Say that ivect and uvect are of type signed and unsigned
303 long instead of int in commentary so that it correctly describes
306 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
308 * stime.c: Removed declaration of strptime. (It should be
309 declared by the system headers. If it turns out that some systems
310 don't, we'll handle that then.) (Thanks to Greg Troxel.)
312 * stime.h: Renamed TIMEH --> STIMEH
314 * backtrace.c (scm_display_error, scm_display_backtrace): In order
315 to increase portability, don't use structure assignment.
316 (Thanks to Nicolas Neuss.)
318 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
320 (finalize_fd_sets): Added empty statement after last case label.
321 (Thanks to Nicolas Neuss.)
323 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
326 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
328 * init.c, readline.c: OK, I won't have these readline.x bug
329 reports anymore. We've had them since April. The current reason
330 is a completely unintelligible failure of totoro.red-bean.com to
331 do the test for rl_getc_function in libreadline correctly. This
332 kludge overrides the test if we're on totoro so that the snapshot
333 generation process can work.
335 * readline.c: Define a strdup replacement if not existent on system.
337 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
339 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
340 This change makes scm_make_vector R5RS compatible. We cannot keep
341 the third argument since people want to be able to deduce the form
342 of the C function call only by looking at R5RS. (At the same time
343 we have removed some unnecessary complexity!)
345 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
346 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
347 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
348 argument in call to scm_make_vector.
350 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
352 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
353 This macro is useful in applications.
355 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
357 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
358 (scm_parse_path, scm_search_path): New Scheme level procedures.
360 * load.h (scm_internal_parse_path, scm_parse_path,
361 scm_search_path): Declared.
363 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
365 * filesys.c (dirname, basename): New procedures.
367 * init.c (scm_boot_guile_1): Removed condition around
370 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
371 new data type (guards) for representation of C level guards and
372 data on the wind chain.
373 (scm_internal_dynamic_wind): New function.
375 * dynwind.h: Declare scm_internal_dynamic_wind.
377 * root.h (scm_root_state): Added scm_cur_loadp.
379 * root.c (mark_root): Added comment about cur_loadp.
381 * load.c: #include "dynwind.h";
382 (scm_primitive_load): Use scm_inner_dynamic_wind to update
385 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
387 * ports.c (current-load-port): New procedure.
389 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
391 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
392 not a tty, return #f.
394 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
395 to Julian Satchell and Roland Kaufmann.)
397 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
398 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
400 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
402 * debug.h, debug.c (scm_start_stack): New function. Implements
403 the guts of old scm_m_start_stack.
405 * debug.c (scm_m_start_stack): Use scm_start_stack.
407 * init.c (scm_start_stack, scm_restart_stack): Renamed to
408 start_stack and restart_stack. (These have static scope.)
410 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
412 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
413 readline functions to come in release 2.3. (Thanks to Chet
415 (handle_errors): Use the above functions.
417 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
419 * readline.c: Improvements for readline support: Handle errors
420 better; Implement before-read-hook.
422 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
424 * init.c (scm_boot_guile_1), readline.c: Test for
425 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
426 assure that we have version >= 2.1.)
428 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
430 * readline.c (scm_readline): Defer interrupts while we're calling
433 * readline.c (scm_add_history): Bugfix: Do strdup before giving
434 away the string to add_history.
435 (completion_function): Do completion for readline. (Thanks to
437 (scm_filename_completion_function): New procedure: Filename
439 (current_input_getc): New function. Use this one instead of
440 standard getc from readline.
442 * throw.c, throw.h (scm_handle_by_throw): New function: This
443 handler throws errors to next handler on the dynwind chain.
445 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
447 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
450 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
452 * procprop.c (scm_i_procedure_arity): New function. Returns arity
454 (scm_procedure_properties): Modified to return arity together with
456 (scm_procedure_property): Added the read-only property `arity'.
457 (scm_set_procedure_property_x): It is an error to set the `arity'
460 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
461 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
463 * procprop.h (scm_sym_arity): New symbol.
465 * objects.c (scm_set_object_procedure_x): New procedure: Use this
466 to set the dispatch procedure of an operator or entity object.
468 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
469 Made procedure slots read-only.
471 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
472 scm_tcs_cons_gloc case in zero args switch; Fixed args
473 construction for operators in scm_tcs_cons_gloc case in two args
476 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
478 * fluids.c: Removed use of assert.h (in order to avoid
481 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
483 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
485 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
486 change makes the evaluator safer at the cost of evaluation speed.
487 It handles the case when the user has added a non-immediate
488 improper end of the application form, e.g., `(+ 0 . x)'.
489 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
490 minimize the extra cost as much as possible. The new code is
491 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
492 problem with structs planted directly in the code (e.g. by a
493 macro). This no longer causes segmentation fault. (Thanks to
496 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
497 arg `proc' in order to be able to throw errors; New argument
500 * Removed extra #include "debug.h"
502 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
504 * scmsigs.c: Declare usleep as returning void on some systems.
505 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
508 * coop.c (usleep): Return void on some systems.
510 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
512 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
514 * coop.c: Changed return type of usleep to int.
516 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
517 isn't found in the OS.
519 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
520 isn't enabled. (Thought that I had made this change ages ago...)
522 * iselect.c: Declare bzero if not defined by OS.
524 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
526 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
527 condition. (Thanks to John Tobey.)
529 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
530 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
533 * __scm.h: Start the long-term project of moving to POSIX threads.
534 Phase 1: Classification of all critical sections.
535 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
536 for A sections. (See comments in __scm.h for details.)
538 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
539 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
541 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
543 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
544 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
545 (libpath.h, versiondat.h): Replaced dependency on Makefile with
546 dependencies on $(srcdir)/Makefile.in
547 $(top_builddir)/config.status in order to avoid circularity.
549 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
550 from argc if argc was 0 initially.
552 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
553 in generation of libpath.h.
555 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
557 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
558 libguile from 2 to 3.
560 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
562 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
564 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
566 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
567 scm_set_port_column_x, scm_port_filename,
568 scm_set_port_filename_x): Removed optional arguments. Added
569 proper argument checking.
571 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
572 stack size in machine words.
574 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
575 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
576 to Ole Myren Röhne.)
578 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
580 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
581 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
583 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
586 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
587 procedure apply: Copy argument lists before pushing them unto the
588 environment so that the environment won't get mutated due to
589 manipulation of procedure arguments. This should perhaps be
590 regarded as a temporary solution until someone finds a more
591 efficient one. (Thanks to Maciej Stachowiak.)
593 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
595 * script.c (scm_compile_shell_switches): Use "guile" as default
596 zero arg if argc is NULL.
598 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
600 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
601 is zero. (Thanks to Dirk Herrmann.)
603 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
605 * ports.c (scm_add_to_port_table): First line is now line 0
606 (was 1). (Interface changed according to suggestion by Per
609 * backtrace.c (display_header): Add 1 to line and column numbers
610 when presenting them to the user.
612 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
613 from debug.c --> eval.c
615 * eval.h, eval.c (scm_eval_options_interface): New options
617 (SCM_EVAL_STACK): New option: Size of newly created stacks,
618 i.e. stacks for new threads.
620 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
622 * eval.c (unsafe_setjmp): Removed with #if 0.
624 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
627 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
628 to avoid compiler warnings.
630 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
632 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
634 * throw.c (handler_message): Print message on current error port
635 instead of default error port. (Thanks to Maciej Stachowiak.)
637 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
639 * ports.c (scm_add_to_port_table): allocate in units of
640 struct scm_port_table *, not struct scm_port_table.
641 * posix.c (scm_close_pipe): remove the port from the port table
643 Thanks to Rob Engle for both fixes.
645 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
647 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
648 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
650 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
652 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
654 * backtrace.c (display_error_body, display_backtrace_body),
655 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
656 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
657 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
658 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
661 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
662 don't receive the jmpbuf arg anylonger.
663 (scm_catch): Don't accept a #f tag.
664 (scm_throw): Check that key is a symbol.
665 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
667 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
669 * async.c (async_pending): Removed declaration.
671 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
673 * dynwind.c (scm_wind_chain): New debug function.
675 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
676 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
677 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
678 extra layer of functions around the body and handler of a thread.
679 This extra layer makes sure that the handler is called in the
680 dynamic context of the surround (= empty dynwind list), but under
681 the *dynamic root* of the body. We can not use the dynamic root
682 of the surround since that root belongs to another thread => stack
683 is not handled correctly. It may seem ugly to use this extra
684 layer, but the extra cost in terms of execution time is really
685 negligible compared to the total amount of time required to create
686 a thread, and it would reduce maintainability to duplicate the
687 crucial and complicated steps performed by cwdr.
689 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
690 (SCM_ALLOW_INTS): Added thread switching code before interrupts
691 get re-enabled. The important effect of this is that interrupts
692 are blocked during thread switching so that thread data structures
693 don't risk getting messed up by an unfortunate signal.
694 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
695 seems to do more aggressive optimization which actually move
696 instructions around in these macros in a fatal way. Therefore:
697 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
698 just superstitious...)
699 (SCM_TICK): Maybe do a context switch and take care of asyncs.
700 This macro should be used instead of SCM_ASYNC_TICK since the
701 latter doesn't do context switches any more.
703 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
704 instead of SCM_ASYNC_TICK.
706 * coop.c, iselect.c: Since thread switches are now performed with
707 interrupts masked, we can't use the old mechanism of delivering
708 signals immediately when they arrive. Signals must instead be
709 delivered when the asyncs run *after* the end of the critical
710 section in scm_internal_select. But this also means after context
711 switch so that the signal will be delivered to a different thread.
712 To avoid this, I have changed the protocol of
713 coop_wait_for_runnable_thread and friends so that they are allowed
714 to return the original thread. So, if a signal arrives during
715 scm_internal_select, we won't any longer be forced do a context
716 switch, but can remain in the same thread and deliver the signal
719 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
720 scm_asyncs_pending and made it global.
722 * iselect.c: Small fixes.
724 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
725 coop_condition_variable_init, coop_condition_variable_wait,
726 coop_condition_variable_signal): Changed return type from `void'
727 to `int'. This is to adhere closer to the pthreads interface.
728 This, in turn, is part of an attempt to provide C versions of the
729 mutex and condition variable primitives which can be part of a
730 frontend to COOP or pthreads.
732 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
733 coop_condition_variable_destroy): New functions.
735 * coop-threads.c (scm_wait_condition_variable): Use
736 coop_condition_variable_wait_mutex.
738 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
739 Definitions moved to coop-defs.h.
741 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
742 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
743 scm_cond_destroy): New C interface to mutecis and cond vars.
745 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
747 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
749 * iselect.c: Now several threads can wait on the same file
750 descriptor. The behaviour is compatible with OS select: All
751 threads waiting for the fd return with the same status.
753 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
755 * coop-threads.c, threads.h (scm_spawn_thread): New function.
756 Can spawn a thread from application C code.
758 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
760 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
761 gh_doubles2scm): New functions.
763 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
765 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
766 commented-out version of gh_eval_str()
768 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
770 * socket.c (scm_bind): free soka after use.
772 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
774 * stime.c (tzvar): new variable.
775 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
776 avoid memory leaks when allocating.
778 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
780 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
783 * gc.c, tags.h: Doc fixes.
785 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
787 * eval.c (macro-eval!): Removed. This function was a design bug.
788 It allowed memoized code to leak out to the scheme level. Most
789 things that you could do with `macro-eval!' can be done with
792 1997-12-20 Tim Pierce <twp@skepsis.com>
794 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
795 scm_fgets now depends on ftell(3) to know how many bytes were
798 1997-12-15 Tim Pierce <twp@skepsis.com>
800 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
801 dealing with strings.
803 1997-12-13 Tim Pierce <twp@skepsis.com>
805 Make %read-line more suitable for implementing read-line efficiently.
806 * ioext.c (scm_read_line): Strip the terminating newline from a
807 string, and return a cons of the string and its terminator.
809 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
810 of the string that is read is stored in this memory location.
811 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
812 * genio.c, genio.h (scm_do_read_line): Update caller.
813 * ports.h (scm_ptobfuns): Update typedef.
814 * fports.c (scm_fptob, scm_pipob): Update struct.
816 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
818 * filesys.c (set_element): Return file descriptor.
819 (fill_select_type): Return the highest file descriptor.
820 (scm_select): Tell select about the highest file descriptor. On
821 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
822 Therefore the extra overhead for calculating the maximum fd seems
823 to be more than compensated. Is this correct? In any case,
824 scm_internal_select will be much faster with this info.
825 (scm_select, fill_select_type, set_element): Don't accept any kind
826 of object in the file descriptor list or vector.
828 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
830 * iselect.c (finalize_fd_sets): Bugfix.
832 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
834 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
835 when using scm_internal_select (since we might switch to another
838 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
840 * simpos.c (scm_system): always define: use sysmissing if not
841 available. Check for HAVE_SYSTEM instead of _Windows (does
842 Windows lack system or does it have an unusable one?).
843 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
844 Let the argument be optional: if not supplied, call system(NULL).
846 * ports.c (scm_close_port): relax the type check from OPPORTP to
847 PORTP; closing a closed port is allowed.
849 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
851 * fports.c (scm_fgets): Return if the last char in a chunk is
852 newline. When fgets returns a string whose length is `size-1', it
853 is ambiguous whether a whole line was retrieved, so we must check
854 explicitly whether a line terminator is present.
856 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
858 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
859 before taking the CDR. (Thanks to Harald Meland.)
861 * filesys.c (scm_stat): Slightly optimized.
863 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
865 * ports.c (scm_close_port): Make sure the port is open before
868 * guile-snarf.in: Pass args through to gcc in a way that preserves
869 whitespace boundaries. (Thanks to Greg Badros.)
871 1997-12-02 Tim Pierce <twp@skepsis.com>
873 * stacks.c (scm_frame_procedure): Reverse the logic in the return
874 statement. (Thanks to Doug Evans for pointing this out.)
876 1997-12-01 Tim Pierce <twp@skepsis.com>
878 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
880 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
882 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
883 errno macro expansion of this field name. (errno is a C
884 preprocessor macro on some systems.)
886 1997-11-29 Tim Pierce <twp@skepsis.com>
888 * iselect.c: Doc fix.
890 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
892 * init.c (scm_start_stack): Removed initialization of
893 scm_the_last_stack_var.
895 * backtrace.h: Declare scm_the_last_stack_var.
897 * backtrace.c: Define scm_the_last_stack_var.
899 * root.c (mark_root): Don't mark the_last_stack_var.
901 * root.h (scm_root_state): Removed the_last_stack_var.
903 * throw.c: Added #include "fluids.h"
904 (ss_handler): `the-last-stack' is now a fluid.
906 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
907 --> the_last_stack_fluid.
909 * backtrace.c: Added #include "fluids.h"
910 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
911 (scm_backtrace): `the-last-stack' is now a fluid.
913 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
914 after scm_init_fluids.
916 1997-11-28 Tim Pierce <twp@skepsis.com>
918 * iselect.c: #ifdef USE_THREADS around thread-related includes.
920 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
921 DLSYM_ADDS_USCORE to decide whether to add an underscore.
923 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
925 * iselect.c (coop_next_runnable_thread,
926 coop_wait_for_runnable_thread): Disable interrupts so that no
927 async is executed before a potential error_revive.
928 (scm_internal_select): Disable interrupts during the parts of the
929 code which manipulate the sleep queue and the file descriptors.
931 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
933 * Makefile.am: Added iselect.c and iselect.h.
935 * coop.c (coop_qinit): Initialize fields used by
937 (coop_qget, coop_qget, coop_tmp_queue): Made global.
938 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
939 replacement in iselect.c.
940 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
941 coop_join): If GUILE_ISELECT enabled, use
942 coop_wait_for_runnable_thread instead of
943 coop_next_runnable_thread.
944 (usleep, sleep): New replacements for system functions if
945 GUILE_ISELECT is enabled.
947 * coop-threads.h: Declare coop_wait_for_runnable_thread.
949 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
951 * filesys.c: Added #include "iselect.h". Moved FD-macros to
952 iselect.h. Implement Scheme level `select' using
953 scm_internal_select. (See NEWS.)
955 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
957 * init.c: Call scm_init_iselect.
959 * iselect.h, iselect.c: New files. Implements
960 scm_internal_select. (See NEWS.)
962 1997-11-27 Tim Pierce <twp@skepsis.com>
964 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
965 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
966 and scm_must_free, since ultimately the string returned will be copied
967 by scm_makfrom0str anyway. Also, read any characters that may have
968 been pushed onto the port with scm_ungetc.
969 * ports.c (scm_generic_fgets): Same as for scm_fgets.
970 * ioext.c (scm_read_line): Free string after Guilifying it.
971 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
973 1997-11-26 Anthony Green <green@hoser.cygnus.com>
975 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
977 * gh.h: Safely wrap prototypes for c++ usage.
979 1997-11-25 Mark Galassi <rosalia@cygnus.com>
981 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
982 gh_repl (argc, argv).
984 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
986 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
987 and to invoke scm_shell().
988 (gh_launch_pad): took out the loading of boot-9.scm from here,
989 since it is probably best to let the user control that. In fact,
990 gh_repl() now invokes scm_shell() which does that.
992 1997-11-23 Mark Galassi <rosalia@cygnus.com>
994 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
997 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
999 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
1000 yesterday's underscore patch. (Thanks to Marius Vollmer for
1003 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
1005 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
1006 DLSYM_ADDS_USCORE is not defined.
1008 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
1010 * gh_data.c (gh_uniform_vector_length):
1011 (gh_uniform_vector_ref): started implementing the uniform types in
1014 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1016 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1017 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1019 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1021 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1022 configure.in was changed).
1024 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1026 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1027 * Makefile.in: Regenerated.
1029 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1031 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1032 OPORT is an `open' port, not an output port.
1034 * filesys.c (scm_close, set_element, get_element, scm_chown,
1035 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
1036 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
1037 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
1038 scm_close_port, scm_port_line, scm_set_port_line_x,
1039 scm_port_column, scm_set_port_column_x, scm_port_filename,
1040 scm_set_port_filename_x, scm_port_mode,
1041 scm_close_all_ports_except, scm_set_current_output_port,
1042 scm_set_current_error_port): Likewise
1043 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1044 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1046 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1047 * backtrace.c (display_backtrace_body): Likewise
1048 * fports (scm_setvbuf): Likewise
1049 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

1056 Minor problems with substring-related tag changes.
1057 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1058 exactly what we want to leave in to detect substrings.
1059 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1060 * tags.h: Fix diagrams and comments describing the S tag bit;
1061 remove vestigial remarks about the D tag bit.

1063 * strings.c: Formatting tweaks.
1065 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1066 variable first; then SCHEME_LOAD_PATH, with a warning message.

1075 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1076 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1077 * Makefile.in: Regenerated.
1078 * scmconfig.h.in: Regenerated, after change to ../configure.
1080 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>

1084 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1086 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1087 with the ! -> _x mapping when going from Scheme to C.
1089 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1091 * gh.h (gh_reverse):
1099 (gh_assoc): added these gh_ functions implemented as macros.
1101 * gh_predicates.c (gh_null_p):
1102 (gh_string_equal_p): added these two missing predicates.
1104 * gh_list.c (gh_append):
1109 (gh_set_cdr_x): added these routines as I go through and try to
1110 complete the picture R4RS functions that should be mirrored in the
1113 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1115 * tags.h (scm_tc7_substring): Changed the comment and code to
1116 conform with the changes below. Folks! We have suddenly two new
1117 free tc7 codes!!! Jummy, jummy!

1150 Don't include "mbstrings.h".
1151 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1152 (SCM_SYMBOL_SLOTS): Define as 4.
1153 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
1154 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
1155 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
1156 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,

1177 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1179 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1181 * gh_test_c.c (c_vector_test): some improvements on the vector
1184 * gh.h (gh_vector): this used to exist but do the wrong thing.
1185 Now it (almost) does the right thing, though it takes a list
1186 instead of the individual arguments. I need to see how it could
1188 (gh_list_to_vector): added this function as a macro. Corresponds
1189 to Scheme's (list->vector ...).
1190 (gh_vector_to_list): added this function as a macro. Corresponds
1191 to Scheme's (vector->list ...).
1193 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1194 gh_vector_ref, so that it resembles the Scheme routines more.
1195 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1196 resembles the Scheme routines more.
1197 (gh_make_vector): this used to be (stupidly) called gh_vector().
1198 This is the right name, since it does the same thing as the Scheme
1199 (make-vector ...) procedure.
1201 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1203 * ports.h: #include "libguile/print.h"
1205 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
1206 Some indentation fixes.
1208 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1209 longer a user field; New field: class_flags.
1211 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1213 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1215 * gh_data.c (gh_bool2scm): new function which replaces
1216 gh_int2scmb(), which is now tagged as obsolete.
1218 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1220 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1221 macros should by convention not test for NIMPness.)
1222 (SCM_COERCE_OPORT): Adjust indentation.
1224 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1225 SCM_NIMP test before SCM_PRINT_STATE_P.
1227 * struct.c, struct.h, gc.c: Renamed:
1228 scm_struct_i_layout --> scm_vtable_index_layout
1229 scm_struct_i_vcell --> scm_vtable_index_vcell
1230 scm_struct_i_vtable --> scm_vtable_index_vtable
1231 scm_struct_i_printer --> scm_vtable_index_printer
1232 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1234 * struct.c (scm_print_struct): Use new printer slot; Default
1235 printing: Also output hex code of vtable so that type identity
1236 will be indicated as well.
1237 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1238 Removed struct_printer_var; Removed struct-vtable-offset;
1239 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1240 vtable-offset-user): New constants.
1242 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1243 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1244 If this slot contains a procedure, use that to print structures of
1245 the type represented by this vtable.
1247 * print.c (scm_iprin1): Don't print arguments of macro
1248 transformers. (They are always: exp env.); Bugfix: Unmemoize
1249 transformer source with correct environment.
1251 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1253 Streamlining of call-with-dynamic-root:
1255 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1256 there is now only one catch.
1257 (cwdr_outer_body): Removed.
1258 (cwdr_handler): New function.
1259 (scm_internal_cwdr): New function to perform the function of cwdr
1260 but take args that are more useful to C code. Also, the handler
1261 is now invoked *outside* of the new dynamic root, like the docs
1262 say. We no longer have to catch absolutely all errors, the caller
1263 is responsible for using a handler that does not throw, if he
1265 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1266 * root.h (scm_internal_cwdr): New prototype.
1268 Even more but risky streamlining:
1270 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1271 allocation of the jumpbuf of a root continuation. The changes
1272 below are controlled by it. They are now deactivated.
1273 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1274 the JMPBUF of the scm_rootcont to NULL before returning.
1276 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1277 when they are non-NULL.
1278 (scm_gc_mark): Likewise, mark only when non-NULL.
1280 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1281 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1283 * gc.c (scm_done_malloc): New function.
1284 gc.h (scm_done_malloc): New prototype.
1286 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1287 (struct scm_print_state) [revealed]: New field.
1288 (scm_print_state_vtable): Make visible to the outside world for
1289 type checking purposes.
1290 (scm_valid_oport_value_p): New prototype.
1292 * print.c (scm_valid_oport_value_p): New function to check whether
1293 a certain value is acceptable as a port argument.
1294 (scm_print_state_vtable): New variable.
1295 (scm_free_print_state): Set `revealed' field to false.
1296 (scm_iprin1): Call user supplied closure printer with
1297 scm_printer_apply. Print in the traditional way when there isn't
1298 one or when it returns #f.
1299 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1300 Accept a port/print-state pair in addition to just a port.
1301 (scm_prin1): Don't return the print_state to the pool when it has
1303 (scm_printer_apply): Set `revealed' field of print_state to true.
1304 (scm_init_print): Set scm_print_state_vtable.
1305 (print_state_fluid, print_state_fluid_num): Removed.
1307 * throw.h (scm_handle_by_proc_catching_all): New prototype
1308 throw.c (scm_handle_by_proc_catching_all): New function
1310 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1312 * Makefile.in: Regenerated with automake 1.2c.
1314 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1316 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1317 was looping endlessly.
1319 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1321 * strports.c (scm_eval_string): Don't close the port.
1323 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1324 former returns a nice normal integer. (Thanks to Daniel
1327 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1329 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1330 makefile variable as a build parameter called LIBS. The
1331 build-guile program will use this, for the time being.
1332 * Makefile.in: Regenerated.
1334 Thanks to Shiro Kawai:
1335 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1336 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1339 * Makefile.in: Regenerated with automake 1.2a.
1341 * script.c (scm_compile_shell_switches): If we hit the -c or --
1342 arguments, don't set the car of (command-line) to scm_usage_name,
1343 the prettified name of the guile executable; give it the full
1344 path, the way shells usually handle $0.
1346 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1348 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1349 Scheme-level name `array-map' and renamed `serial-array-map' to
1350 `serial-array-map!'.
1352 * backtrace.c: Introduced exception handlers which now enclose
1353 `display-error' and `display-backtrace' so that error reporting
1354 won't get into infinite loops if an error occurs during displaying
1355 of the error. This can very easily happen with user supplied
1356 print call-back routines.
1358 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1360 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1361 the names `serial-array-map' and `array-map' should be removed.)
1363 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1365 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1366 Added #include "objects.h"
1368 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1369 Add #include "feature.h".
1371 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1372 (modinclude_HEADERS): Added objects.h.
1374 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1375 This test is needed at many places in the code and should be
1376 abstracted. (Motivated by the need of this test in libguiletk.)
1378 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1379 (scm_eval_string), load.c (scm_primitive_load,
1380 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1381 Use SCM_EOF_OBJECT_P.
1383 * eval.c (scm_init_eval): Add feature `delay'.
1385 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1387 * scmhob.h: Removed.
1389 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1391 * list.h (SCM_LISTn): New macros. Make list creation in C code
1392 prettier. The idea comes from STk.
1394 * sequences.h, sequences.c, append.h, append.c: Removed. These
1395 files implemented non-R4RS operations which would encourage
1396 non-portable programming style and less easy-to-read code.
1398 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1401 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1402 sequences.h, #include append.h.
1404 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1407 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1409 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1411 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1413 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1415 * eval.c: Added #include "objects.h"
1417 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1420 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1421 adjacent smob numbers.
1423 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1425 * procprop.h: Added declaration of scm_i_inner_name.
1427 * gsubr.c: New global symbol scm_i_inner_name.
1429 * debug.c (scm_procedure_name): Try procedure property
1430 `inner-name' if `name' fails.
1432 * print.c (scm_iprin1): Use scm_macro_name.
1434 * eval.c (scm_m_define): Give names to macros as well; Only the
1435 first top-level definition gives a procedure/macro a name.
1436 Otherwise confusing names can turn up in backtraces.
1437 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1438 `name'; Give names to macros as well.
1440 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1441 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1444 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1446 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1448 (prinmacro): Removed. The code has been moved/merged into print.c
1449 in order to decrease code redundancy. We want macros to print in
1450 a way equivalent to procedures, and it would be silly to duplicate
1451 the required code. (We don't want to maintain two places.)
1452 (macrosmob): Print field is now a NULL pointer.
1454 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1455 scm_macro_transformer): New prototypes.
1456 (scm_tc16_macro): Declared.
1458 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1459 are now printed in a way equivalent to procedures.
1461 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1463 * procs.h (scm_closure_p): Added declaration.
1465 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1467 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1468 Shouldn't pass "heap" as the subr name.
1470 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1472 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1473 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1474 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1475 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1476 SCM_BOOL_T. Any non-false value is true.
1478 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1480 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1481 scm_gensym): Added prototypes.
1483 * symbols.c (scm_gensym): New function. This will speed up
1484 certain types of applications (such as macro systems) which
1485 generate lots of symbols.
1487 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1489 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1491 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1493 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1494 specifier, since (2) or (2 . 3) would cause SEGV.
1495 (scm_transpose_array): more argument checking fixes.
1497 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1499 * Makefile.in: Regenerated.
1501 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1503 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1505 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1507 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1509 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1511 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1512 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1515 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1516 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1517 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1518 scm_array_p, scm_array_rank, scm_array_dimensions,
1519 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1520 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1521 scm_array_prototype): Added case scm_tc7_wvect.

1530 * list.c (scm_list_append_x): Allow non-pair as last argument.
1531 This is consistent with the R4RS append and is probably the
1532 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1534 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>

1554 third argument is now optional.
1556 * posix.c (scm_execl, scm_execlp): make the filename argument
1557 compulsory, since omitting it causes SEGV.
1558 (scm_sync): return unspecified instead of #f.
1559 (scm_execle): new procedure.
1560 (environ_list_to_c): new procedure.
1561 (scm_environ): use environ_list_to_c. disable interrupts.

1567 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1568 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1569 argument to SCM_ASSERT. Furthermore, the name of the function
1570 should be passed as first argument when signalling
1571 SCM_WNA. (Thanks to Thomas Morgan)
1573 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1574 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1575 dispatches on the number of actual args has a default case
1576 reporting an internal error. This is a vestige from a version
1577 that mallocated a SCM vector to hold the arguments. In the
1578 current version this check is too late: if it ever happens we will
1579 have already overstepped the bounds of the array.
1581 Also, the patch [...] adds a check for too many actual arguments."
1583 mdj: Removed check for "internal programming error".
1585 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1587 * gh_io.c (gh_write): New function.
1589 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:

1602 fold in the functionality of scm_primitive_dup.
1603 (scm_primitive_dup): deleted.

1608 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1609 ultrix are defined. Use setvbuf instead of setbuf.

1627 (scm_iprin): If print_state_fluid carries a print_state, use that
1628 instead of creating a new one.

1630 definitions to help with calling printer functions written in
1632 * print.h (scm_printer_apply): New prototype.

1650 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied

1730 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1731 the dynamic object data below the linking of the object to avoid
1732 memory leak when the linking code throws an error. Now the code
1733 leaks a whole dynamically linked library when must_malloc throws,
1734 but that should be much less likely.
1736 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1738 Changes to compile under gnu-win32, from Marcus Daniels:

1776 think this is left over from the (eq? '() #f) days.
1778 * read.c (recsexpr): Give this a dummy definition if
1779 DEBUG_EXTENSIONS isn't #defined.
1781 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

1809 turn off REG_EXTENDED.
1810 (scm_init_regex_posix): New regexp/basic symbol.
1811 (REG_BASIC): #define this if it is not already present.

1871 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
1872 the feeling that real thread systems will not need this...
1874 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
1876 Try to detect when people are using one version of libguile and a

1890 * Makefile.am (libguile_la_LDFLAGS): Update library version to
1891 1:2. Helps avoid confusion between installed and uninstalled libs.
1893 * scmconfig.h.in: Regenerated. (Needed after June 3 change to

1916 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
1918 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA

1923 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
1924 top of the word, it should be unsigned.
1926 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
1927 is defined, to avoid warnings; it's only used in the
1928 conflict-checking code. Which might go away anyway.
1929 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
1930 conditionals; put the label definition in an #if too, to stifle
1933 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
1934 ChangeLog-threads in the distribution.

1980 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
1982 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
1983 supplied. (Change from Tim Pierce.)
1985 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
1987 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
1988 23:47:01 1997" changelog: Slots are now initialized with `#f' by
1989 default and not `()'. `#f' is the canonical non-value in Scheme,
1992 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1994 * struct.c (struct_printer): New variable that holds a handle on
1995 the Scheme variable *struct-printer*. This variable can be set by
1996 Scheme code to override the printing of structures.
1997 (scm_print_struct): If struct_printer is set, call it. If it is
1998 not set, or returns #f, print the structure in the old fashion.
1999 Include "eval.h" for scm_apply.
2001 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2003 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2004 scm_struct_i_n_words to get the number of fields, not
2005 -scm_struct_n_extra_words.
2007 On the route to fancier struct printing:
2008 * struct.c (scm_print_struct): New function to print a structure.
2009 Include "genio.h" to support it. This function doesn't do
2010 anything interesting right now, but I think it should be here
2012 * struct.h: Include "print.h" and add prototype for
2014 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2015 print structures ourself.
2017 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2019 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2020 before applying the handler in case it doesn't return.
2022 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2024 * scmsigs.h, async.h: updated.
2026 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2029 * posix.c (scm_uname): interpret only negative values as an error.
2030 Solaris normally returns a positive value.
2032 * script.c (scm_compile_shell_switches): if we are not going into
2033 an interactive repl, set scm_mask_ints to zero so that asyncs can
2036 * simpos.c (scm_system): don't ignore/unignore signals around
2039 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2042 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2043 done in boot-9.scm instead.
2045 * scmsigs.c, async.c: Major rewriting of signal handling code.
2046 (scm_sigaction): new procedure.
2047 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2049 (scm_raise): return unspecified, throw error on failure.
2051 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2053 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2054 feature, to help boot-9.scm decide whether to import the regex
2057 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2059 * eval.c: Include scmconfig.h at the beginning of the file so that
2060 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2063 * regex-posix.c: #include "_scm.h" before conditionally #including
2064 <regex.h>; the former defines HAVE_REGCOMP.
2066 * regex-posix.c: #include <regex.h> conditionally, so the file is
2067 CPP'able (for dependency scanning) even on systems that don't have
2070 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2072 Add new R4RS-compliant syntax for keywords.
2073 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2074 regardless of the setting of the `keywords' read option.
2075 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2076 can be re-read no matter what the setting of the `keywords' read
2079 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2081 Add support for POSIX regular expressions.
2083 * regex-posix.c, regex-posix.h: New files. (Some code
2084 is taken liberally from rx/rgx.c in the old Guile dist.)
2086 * init.c: Include regex-posix.h.
2087 (scm_boot_guile_1): Call scm_init_regex_posix.
2089 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2090 Add regex-posix.[ch] sources.
2091 * Makefile.in: Regenerated.
2093 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2094 to do this automatically? It didn't for me, bleh.)
2096 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2098 * fports.c (print_pipe_port): New function.
2099 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2100 latter doesn't even take the right arguments.
2102 * Makefile.am: Increment shared lib revision number. I think
2103 sometimes the uninstalled Guile finds the installed shared lib;
2104 Gord says doing this might help. As things turned out, I can't
2105 say whether it does.
2106 * Makefile.in: Regenerated.
2108 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2109 passing it as the closure argument to scm_boot_guile. (Bill
2112 * ports.c (print_void_port, putc_void_port, puts_void_port,
2113 write_void_port, flush_void_port, getc_void_port, close_void_port,
2114 noop0): Use ANSI prototypes instead of K&R declarations, so the
2115 initialization of void_port_ptob gets aggressively type-checked.
2116 Fix arguments of print_void_port and write_void_port. (Bill

2150 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2152 * script.c (scm_find_executable): Use prototype-style definition
2153 here; apparently it's not quite right to have const in a prototype
2154 and then use a K&R declaration. I wonder if stuff like this will
2155 go away if we compile with -Wrequire-prototypes, or whatever that
2156 is... (Bernard URBAN)
2158 * scmhob.h: New text from Bernard URBAN.
2160 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2162 * script.c: Don't #define const on hpux. Configure takes care of
2163 this. (Thanks to Larry Schwimmer.)
2165 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2166 decide whether to #include <unistd.h>, instead of listing a bunch
2167 of systems. Don't #include stdio twice. Removed dyked-out
2168 definition of scm_find_impl_file.
2170 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2172 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2173 library version info to 1:0.
2174 * Makefile.in: Regenerated.
2176 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

2180 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2181 throw.c: Update copyright years; these files have been worked on
2182 significantly in 1997, but only had copyright years for 1996.
2183 Also, change name of copyright holder on some from Mikael
2184 Djurfeldt to Free Software Foundation; he has signed papers
2185 assigning the changes to the FSF.
2187 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2188 reason not to give the user the option.
2190 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2191 Return #f on end-of-file when scanning table (i.e. when called
2192 with no arguments). Try to catch errors, when we can.
2193 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2195 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2196 external declarations. These are useful.
2198 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2200 * posix.c: don't include <sys/select.h> or define macros for
2201 select, since they were not used in this file.
2203 * filesys.c (scm_select): make the fifth parameter microseconds,
2204 not milliseconds. let the fourth parameter be either a real value
2205 or an integer or #f. The first, second and third arguments can
2206 now be vectors: the type of the corresponding return set will be
2208 (set_element, get_element): new static procedures.
2210 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2212 * strports.c (scm_eval_string): New function.
2213 (scm_eval_0str): Trivially re-implemented in terms of
2215 * strports.h (scm_eval_string): New extern decl.
2217 * net_db.c (h_errno): Add extern decl for this.
2219 * fports.c (local_pclose): New function.
2220 (scm_pipob): Use it in the initializer here.
2223 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2224 Use a meaningful error message when signalling an error. For
2225 this, scm_gethost must check h_errno rather than errno.
2227 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2229 * Makefile.in: Regenerated, using automake-1.1p.
2231 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2233 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2234 not SCM_UNSPECIFIED.
2236 * script.c (scm_compile_shell_switches): don't append (quit) if
2238 (scm_shell): call scm_exit_status and exit on the result of the
2241 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2243 Ensure that shared substrings are handled properly when passed to
2244 a system call or other foreign function. Many thanks to Tim
2246 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2247 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2248 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2249 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2251 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2252 (scm_display_error_message): use RO macros when strings may be RO.
2253 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2254 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2255 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

2259 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2260 scm_strftime), vports.c (scm_make_soft_port): use
2261 SCM_COERCE_SUBSTR to make sure shared substrings are
2264 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2266 * error.c (scm_error): Add newline to error message.
2268 * init.c (scm_init_standard_ports): Doc fix.
2270 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2272 * dynl-shl.c: Completely replaced with new code from Bernard
2275 * script.c (scm_ice_9_already_loaded): New variable.
2276 (scm_compile_shell_switches): Use it.
2278 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2280 * filesys.c (scm_input_waiting_p): add missing third argument to
2283 * stime.c (scm_localtime): copy the result of localtime before
2284 calling gmtime in case they share a buffer.
2285 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2288 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2290 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2292 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2294 * Makefile.am (check-local): New target, which causes 'make check'
2295 to run gh_test_c and gh_test_repl, with some trivial input.
2296 * Makefile.in: Rgnrtd.
2298 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2300 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2303 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2305 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2306 sure how this was supposed to work.
2307 (scm_async_click): don't send SCM_TICK_SIGNAL.
2308 (scm_init_async): don't initialize %tick-thunk.
2310 * the following change doesn't affect the Scheme interface:
2311 gc-thunk is called at the end of garbage collection. however it's
2312 no longer implemented by pretending it's a signal.
2314 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2315 system async corresponding to scm_gc_thunk.
2316 * async.h: declare scm_gc_async.
2317 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2318 gc-thunk directly, instead of going through a signal handler.
2319 (scm_gc_async): new variable, points to the GC system-async.
2320 (scm_init_async): save the GC async as scm_gc_async instead
2321 of using system_signal_asyncs.
2322 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2324 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2326 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2327 Don't screw up if we're interrupted.
2328 * Makefile.in: Regeneradet.
2330 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2332 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2334 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2335 we're not using AM_INIT_GUILE_MODULE any more.
2336 * Makefile.in: Reneregated.
2338 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2340 Functions for finding variable bindings, grace à Tim Pierce.
2341 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2342 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2344 Get 'make dist' to work again.
2345 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2346 * Makefile.in: Regenerated, like a surry without a fringe on top.
2348 Changes for reduced Guile distribution: one configure script,
2350 * configure.in, configure: Removed.
2351 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2352 real configure script lives.
2353 * Makefile.in, scmconfig.h.in: Regenerated.
2355 * init.c: #include "script.h", to get prototype for script.c's
2358 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2360 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2361 scm_must_malloc, not raw malloc.
2363 * script.c (scm_compile_shell_switches): Dyke out debugging output
2366 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2368 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2370 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2371 system has them. Hope this is safe. Previously
2372 sys/timeb.h was included if HAVE_FTIME was defined or if
2373 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2374 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2376 * ioext.c (scm_setfileno): add missing third argument to
2377 scm_misc_error call.
2379 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2381 * eq.c (scm_equal_p): Correctly compare strings of different
2382 varieties. (Thanks to Tim Pierce.)
2384 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2386 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2387 #! block comment must occur on a line all by itself.
2389 Move most of the guts of shell command processing into libguile,
2390 so guile.c can be very small (and eventuallly auto-generated. (I
2391 mean, generated mechanically, not self-generated. Hmm.))
2392 * guile.c, script.c, script.h: New source files.
2393 * init.c (scm_boot_guile_1): Call scm_init_script.
2394 * libguile.h: #include "script.h".
2395 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2396 targets, for new executable.
2397 (libguile_la_SOURCES): Mention script.c.
2398 (modinclude_HEADERS): Add script.h.
2399 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2400 not dynamic linking is enabled. This is because we're generating
2401 executables now. Move CY_AC_WITH_THREADS call after those, so the
2402 values of cy_cv_threads_libs captures the libs chosen above.
2403 * Makefile.in, configure, aclocal.m4: Regenerated.
2405 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2406 We don't maintain this interface any more, and it just confuses
2409 * alloca.c: #include <scmconfig.h>, not <config.h>.
2410 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2411 it'll get included in disties.
2413 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2415 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2416 be distributed, because they confuse people.
2417 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2419 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2421 * configure.in: check for presence of gethostent (not present on
2422 OpenBSD by default).
2423 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2424 * configure, scmconfig.h.in: Regenerated.
2426 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2428 * backtrace.c (scm_backtrace): Split message string across
2429 newlines properly. GCC is more tolerant of this than other
2432 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2434 Merge threads directory into libguile.
2435 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2436 threads.h: New source files.
2437 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
2438 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2440 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2441 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2442 coop-threads.c.cygnus, coop-threads.h.cygnus.
2443 * configure.in: If we're using threads, include threads.o in
2445 * _scm.h, libguile.h: threads.h lives in this directory now.
2446 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2447 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2448 currently used, but brought along for information's sake.
2449 * ChangeLog-threads: log from old 'threads' directory.
2450 * Makefile.in, configure: Rebuilt.
2452 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2454 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not

2459 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2461 Merge GH interface library into libguile.
2462 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2463 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2464 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2465 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2467 (EXTRA_libguile_la_SOURCES): ... here.
2468 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2469 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2470 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2471 New variables, describing how to build the gh test programs.
2472 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2473 build the test programs, and we probably should have been linking
2474 libguile.la against them all along, to support AIX shared libs.
2475 Add cflags for threads to CFLAGS; add libs for threads to new
2476 variable THREAD_LIBS, used in Makefile.am.
2477 * ChangeLog-gh: log from old `gh' subdirectory.
2478 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2480 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2482 * acconfig.h: Undo change of Apr 9; including the definition of
2483 PACKAGE in the guile headers conflicts with applications' own
2485 * scmconfig.h.in: Regenerated.
2487 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

2496 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2498 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2499 have S_IFSOCK. This is the case under Ultrix.
2501 * posix.c (scm_status_exit_val, scm_status_exit_val,
2502 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2503 Ultrix versions of WIFSTOPPED, etc., which assume that their
2504 arguments are lvalues (hmm).
2506 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2508 * eval.c: Doc fixes.
2510 * throw.c: Doc fixes; rearranged.
2512 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2514 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2516 * acconfig.h: Added entry for PACKAGE.
2517 * scmconfig.h.in: Regenerated.
2519 Changes to work with automake-1.1n, which has better libtool support.
2520 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2521 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2523 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2525 * Makefile.in: Rebuild.
2527 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2529 * stime.c (scm_mktime): take an optional zone argument.
2530 (scm_localtime): check putenv return value.

2534 (bdtime2c, setzone, restorezone): new static procedures.
2535 (scm_mktime, scm_strftime): use them.
2536 (scm_strftime): don't call mktime before strftime. Use
2537 filltime for return value.
2538 (filltime): convert NULL zname to #f.
2539 (scm_strptime): return a count of characters consumed, not
2540 the remaining string.

2553 * stime.c (scm_init_stime): don't define ticks/sec.
2554 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2555 return value problem and is still portable.)
2557 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2559 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2560 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2561 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2562 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2563 cpp_err_symbols.c): Corresponding changes.
2564 * Makefile.in: Regenerated.
2566 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2568 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2569 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2570 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2571 * putenv.c: new file, from sh-utils 1.12.
2573 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2574 since allocation isn't for Scheme objects.
2575 (scm_putenv): copy strings before placing in the environment.
2577 * stime.c (scm_current_time): throw an error if time returns -1,
2578 instead of returning #f.
2579 (scm_get_internal_real_time, scm_get_internal_real_time): use
2580 scm_long2num for return value instead of SCM_MAKINUM.
2582 * stime.h: prototypes updated.
2584 * stime.c (scm_time_in_msec): apparently unused, deleted.
2586 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2588 * configure.in: check for gettimeofday.
2590 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2591 which may be more usefully portable than a gettimeofday interface.
2593 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2595 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2597 * Makefile.in: Regenerated.
2599 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2601 * stime.c (filltime): recovered static procedure.
2602 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2605 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2606 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2608 * posix.c (scm_mknod): split the mode argument into type and perms
2609 arguments, like the extra fields returned by stat.
2611 * fports.c (scm_pipob): set the close, free and print procedures.
2612 (scm_close_pipe): new procedure.
2614 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2615 define them in boot-9.scm
2617 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2619 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2620 wan't defined. Don't include fd.h.
2622 * Previously fd.h was regenerated whenever configure was run,
2623 forcing a couple of files to be recompiled.
2625 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2626 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2627 Check for _fileno as well as _file.
2629 * ioext.c: don't fd.h.
2630 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2633 * Change the stratigy for getting information about errno
2634 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2635 generating lists of symbols during the build process, which will
2636 not always work, include comprehensive lists in the distribution.
2637 To help keep the lists up to date, the "check_signals" and
2638 "check_errnos" make targets can be used.
2640 * configure.in: don't check for a command to extract errno codes.
2641 * Makefile.am: update file lists, remove errnos.list and errnos.c
2642 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2643 check_errnos targets.
2644 (CLEANFILES): remove errnos.c and errnos.list, add
2645 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2646 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2647 * errnos.default: deleted.
2648 * cpp_signal.c: new file.
2649 * cpp_errno.c: renamed from errnos_get.c.
2650 * cpp_err_symbols, cpp_sig_symbols: new files.
2651 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2652 * error.c (scm_init_error): #include cpp_err_symbols instead of
2654 * posix.c (scm_init_posix): don't intern signal symbols. #include
2657 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2659 * strop.c (scm_i_index): allow the lower bound to be equal to the
2660 length of the string, so a null string doesn't always give an error.
2662 * posix.h: new prototypes.
2663 * posix.c (scm_status_exit_val, scm_status_term_sig,
2664 scm_status_stop_sig): new functions, as in scsh. They break down
2665 process status values as returned by waitpid.
2667 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2669 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2670 configure doesn't know about it.
2672 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2674 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2676 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2677 which defines C variables with global linkage.
2679 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2681 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2684 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2686 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2687 has time to check why this doesn't work well with continuations.
2689 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2691 * Fix shell syntax error; some shells won't tolerate
2692 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2694 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2696 * posix.c (scm_uname): throw an error if uname fails instead
2699 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2701 * error.c (err_head, scm_errno, scm_perror): obsolete procedures

2706 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2708 * acconfig.h: Removed PACKAGE.
2710 * scmconfig.h.in: Regenerated.
2712 * snarf.h: g++ says it's non-portable not to specify the first
2713 argument in a varargs declaration. I introduced the first
2714 argument by using preprocessor conditionals.
2716 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2718 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2719 (scm_freopen): use RO string macros for filename and modes.
2720 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
2722 * posix.c (scm_getgrgid): simplify conversion of name to C string.
2723 (scm_mknod): use RO string macros for path.
2725 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2726 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2728 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2729 use SCM_ROSTRINGP and SCM_ROCHARS.
2731 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2733 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2736 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
2737 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
2738 support for byte vectors.
2740 * print.c (scm_iprin1): Limit number of vector elements printed
2741 according to pstate->length.
2743 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2745 * backtrace.c (scm_display_error_message): don't segv if message
2748 * error.h: prototype for scm_error_scm.
2750 * error.c (scm_error_scm): new procedure, reimplements scm-error
2751 in C and uses scm_error.
2753 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2755 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2756 pointer to the Scheme variable read-hash-procedures and intern it
2757 in scm_init_read. Modify scm_read_hash_extend and
2758 scm_get_hash_procedure to use the pointer.
2760 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2762 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2763 (SCM_KEYWORD_STYLE): defined.
2765 * read.c (scm_read_opts): add a keywords option. This isn't a
2766 boolean option, in case someone wants to add support for DSSSL
2768 Setup scm_keyword_prefix symbol.
2769 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2771 I've left keyword support disabled by default, since it doesn't
2772 seem to break the module system and it gives R4RS standard behaviour.
2773 It can be reactivated with (read-set! keywords 'prefix).
2775 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2777 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2778 before constructing arbiter.
2780 * eval.c (scm_m_define): Bugfix: Check that the object is a
2781 closure before setting the procedure property!
2783 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2785 * ports.c: Removed `ungetc-char-ready?'.
2787 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2789 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2790 (idea from Mikael: make it a pair so scm_permanent object only
2792 (scm_read_hash_extend): don't call scm_permanent_object.
2793 (ideas from Mikael): if chr is already in the list, replace its
2794 procedure instead of appending it again. If proc is #f, remove
2796 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2798 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
2800 * gdbint.c (gdb_read): update scm_lreadr usage.
2802 * load.h: update prototypes.
2804 * load.c (scm_primitive_load, scm_read_and_eval_x,
2805 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
2807 * read.h: add prototype for scm_read_hash_extend. Change args for
2810 * read.c (scm_read_hash_procedures): new variable.
2811 (scm_read_hash_extend): new procedure.
2812 (scm_get_hash_procedure): new procedure.
2813 (scm_lreadr): use scm_get_hash_procedure instead of an argument
2814 for extended # processing.
2815 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
2816 scm_read_token): remove case_i, sharp arguments. Change callers.
2818 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
2820 * read.h (SCM_N_READ_OPTIONS): increase to 3.
2821 (SCM_CASE_INSENSITIVE_P): define.
2823 * read.c: add case-insensitive option to scm_read_opts.
2824 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
2825 to determine whether to convert symbol case.
2826 (default_case_i): definition removed.
2827 * read.c (scm_read_token): if case_i, downcase ic before doing
2830 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2832 * configure.in: Added configuration option `guile-debug'.
2833 Configure with --enable-guile-debug if you want a bunch of extra
2834 functions used for debugging when developing Guile.
2836 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
2838 * procs.c (make-cclo): New undocumented debugging procedure: Make
2839 compiled closure with internal procedure PROC and length LENGTH.
2840 Only compiled if GUILE_DEBUG is defined.
2842 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
2844 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
2846 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
2848 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
2849 with 3 or more args internally to the evaluator.
2851 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2853 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
2854 with 3 or more args internally to the evaluator. This is mainly
2855 because we don't want to pass entry and exit points of the
2856 debug support twice, but it also seems to increase the speed of
2857 the evaluator for such calls (e. g. (+ 1 2 3)).
2859 * backtrace.c (scm_display_application): New procedure:
2860 display-application; Set fancy printing parameters individually
2861 for different types of display (backtrace, error, application).
2862 (These should of course be customizable!)
2864 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
2865 clear the CHECK-flags.
2867 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2869 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
2871 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2873 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
2874 from pairs with a GLOC in the car.
2876 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
2877 otherwise `symbol-hash' will behave badly.
2878 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
2879 we get segmentation fault!
2881 * symbols.c: Added #include "weaks.h". New functions:
2882 `builtin-bindings' and `builtin-weak-bindings'. (These will be
2883 moved to an extraneous library when we split libguile.)
2885 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2887 * filesys.c (scm_stat): stat now takes fport arguments too as
2888 documented in the manual.
2890 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2892 * debug.c (scm_single_step): Bugfix: Call continuation with
2893 scm_call_continuation instead of throwing to it.
2895 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2897 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
2898 argument wasn't declared to be optional.
2900 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2902 * stime.c (scm_init_stime): Add feature "current-time".
2904 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2906 * throw.h: prototype for scm_exit_status.
2907 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
2908 args to derive an exit status. Allows (quit) to work from a
2910 (scm_exit_status): new function.
2913 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2915 * eval.c (scm_deval): Removed some old code.
2916 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
2918 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
2921 * symbols.c (msymbolize): Bugfix: Must initialize property list to
2924 * procs.c: Introduce the existent C function scm_thunk_p at the
2925 Scheme level as well.
2927 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2929 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
2930 used from C to easily lookup the value of a symbol in the current
2933 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2935 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
2936 scm_init_unif in this file. This will also fix a previous problem
2939 * configure.in: Added AM_MAINTAINER_MODE
2941 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2943 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
2946 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2948 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
2949 source files that are not always included in libguile but should
2950 have their dependencies calculated by automake. This variable is
2951 recognized by automake, no further magic is needed.
2952 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
2953 to deal exclusively with *.lo files, as it seems. The *.o files
2954 are built automatically when the corresponding *.lo file gets
2957 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
2959 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
2962 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
2964 * unif.c (scm_array_set_x): minor change to argument error checking.
2966 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
2968 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
2969 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
2970 They should only be included in the library at configure.in's
2972 (libguile_la_LDADD): Include the appropriate .lo files here.
2973 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
2974 so we know when to build them (and their .lo bretheren).
2975 * configure.in (LIBLOBJS): New substituted variable. We let
2976 configure decide which .o files to include in LIBOBJS, and then
2977 put the corresponding list of .lo files in LIBLOBJS. The latter
2978 is what we pass to libtool.
2979 * Makefile.in, configure: regenerated.
2981 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
2983 * symbols.c (scm_sysintern0): New function. Contains the core of
2984 old scm_sysintern but doesn't take a second value argument.
2985 (scm_sysintern): Now uses scm_sysintern0.
2986 (scm_sysintern_no_module_lookup): Renamed to
2987 scm_sysintern0_no_module_lookup and doesn't take a second value
2988 argument any longer.
2990 * symbols.h (scm_sysintern0: Added declaration.
2992 * options.c (scm_init_opts): Use scm_sysintern0 instead of
2993 scm_sysintern when interning option keys. Otherwise we risk
2994 destroying the values of already interned variables.
2996 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
2997 scheme-level boolean (use SCM_NFALSEP).
2999 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3001 (scm_backtrace): New function. (C version of old function from
3002 boot-9.scm) Motivation: Make it possible to display backtraces
3003 without depending on boot-9.scm. (I'm uncertain if this
3004 motivation is good enough...)
3006 * root.h (scm_root_state): Add member the_last_stack_var.
3007 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3009 * root.c (mark_root): Mark scm_the_last_stack_var.
3011 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3014 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3016 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3017 1. mark_lazy_catch didn't mark the smob.
3018 2. Both functions above have standard variants:
3019 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3020 free_lazy_catch --> scm_free0.
3022 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3024 * throw.c (scm_internal_lazy_catch): New function.
3025 (scm_lazy_catch): Rewritten to use it.
3026 (scm_ithrow): Handle the new lazy catch representation.
3027 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3028 that doesn't have a jmpbuf is a lazy catch clause.
3029 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3030 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3031 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3033 (scm_init_throw): Register the new lazy-catch smob type.
3034 * throw.h (scm_internal_lazy_catch): decl for new function.
3036 * throw.c (scm_internal_catch): Doc fixes.
3038 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3039 configure.in. Including this might cause problems if applications
3040 that link against libguile include their own copies of alloca, but
3041 if they're using autoconf, they should be adding libguile to LIBS
3042 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3043 the copy in libguile, and things will be okay. (I think.)
3045 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3047 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3049 strop.h: move prototypes too.
3051 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3053 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3056 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3057 etc. I deleted them from filesys.c long ago, but didn't
3058 notice they were here too (although ineffective since
3059 sys/stat.h wasn't included).
3061 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3063 * eval.c: Don't define alloca in GCC case. gcc will automatically
3064 use __builtin_alloca if appropriate.
3066 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3068 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3069 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3070 that values of automatic variables are preserved. See comments
3071 for safe_setjmp for details.
3073 Change from Thomas Morgan:
3074 * variable.c: Include eq.h.
3075 (var_equal): New function.
3076 (variable_smob): Use var_equal as the discriminator for variables.
3078 * throw.c (s_throw): Remove extraneous declaration.
3080 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3081 * eval.c: Add necessary CPP cruft to support that.
3082 * configure, Makefile.in, scmconfig.h.in: regenerated.
3084 Change from Thomas Morgan:
3085 * procprop.c (scm_procedure_properties): Convert the Scheme
3086 boolean returned by scm_procedure_p into a C boolean before using
3087 it as a condition for SCM_ASSERT.
3088 (scm_procedure_property): Likewise.
3090 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3091 indications of Unixness.
3094 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3096 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3098 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3100 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3101 "unknown # object" error messages.
3103 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3104 (scm_i_index) and declare it static. Add a 'direction' argument
3105 to indicate what way the search should go.
3106 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3108 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3109 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3111 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3113 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3115 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3116 to avoid clash with various scsh forks.
3118 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3120 The following two changes (ramap.c, throw.c) are motivated by the
3121 apparent unportability of forward declarations of static arrays of
3122 the form `static foo bar[];'.
3124 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3125 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3127 * throw.c (scm_throw): Moved above scm_ithrow.
3129 * options.h: Removed the extern declarations of scm_yes_sym and
3130 scm_no_sym since these are static.
3132 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3134 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3136 * Makefile.am: remove AWK=@AWK@.
3137 Add a rule for generating errnos.list.
3138 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3140 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3141 don't extract errnos, just set a variable (avoids the
3142 need to recompile error.c just because configure is run.)
3144 * unif.h: update prototypes.
3145 * unif.c (scm_uniform_array_read,write): change the offset and
3146 length arguments to start and end, for consistency.
3148 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3150 * ioext.h: update prototypes.
3151 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3152 scm_read_line_x, it's a more general procedure using an
3153 interface from scsh. read-line and read-line! are now defined
3155 Note that the new read-line trims the terminator
3156 by default, previously it was appended to the returned string. An
3157 optional argument specifies how to process the terminator (scsh
3158 compatible). For the old behaviour: (read-line port 'concat).
3159 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3160 returns a pair, but is converted to multiple values if the scsh
3163 socket.h: update prototypes.
3164 * socket.c (scm_recvfrom): for consistency with other procedures,
3165 take start and end as separate optional arguments.
3166 (scm_recv, scm_recvfrom): don't allow the second argument
3167 to be a size, only a buffer. Change the scheme names to
3168 recv! and recvfrom!. Don't return the buffer.
3170 * ioext.h, posix.h: move prototypes too.
3171 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3172 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3173 "read.h" and "unif.h".
3174 * ioext.c: include "chars.h"
3176 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3178 * dynl.c: The dynamic linking and module registration functions
3179 are now defined even when dynamic linking is not available for the
3180 host system. Some of their functionality can be done without
3181 dynamic linking; when it's really needed, they throw errors.
3183 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3185 * configure.in: Only define DYNAMIC_LINKING when one of the system
3186 dependent functions is detected.
3187 * dynl.c (scm_dynamic_func): New function to get the address of a
3188 function in a dynamic object.
3189 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3190 produced by scm_dynamic_func as the thing to call.
3192 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3194 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3195 (scm_register_module_xxx, scm_registered_modules,
3196 scm_clear_registered_modules): New functions.
3198 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3200 * symbols.c (scm_sysintern): Renamed to
3201 scm_sysintern_no_module_lookup.
3202 (scm_sysintern): New function to take the place of the old
3203 scm_sysintern. It uses the current toplevel lookup closure to give
3204 the symbol its value. This is a temporary hack to put packages
3205 like gtcltk into their own module.
3206 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3207 us whether `scm_top_level_lookup_closure_var' has been initialized
3209 * eval.c (scm_init_eval): Set it.
3211 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3213 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3214 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3216 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3218 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3219 scm_sys_dup): deleted: FD capability will be added to other
3221 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3222 scm_fd_free, fd_smob, scm_intern_fd.
3223 (scm_open): renamed from scm_sys_open. Return a port instead of
3224 an FD object. Make the mode argument optional.
3225 (scm_sys_create): deleted, it's just a special case of open.
3226 (scm_init_filesys): move interning of constants O_CREAT etc.,
3227 here (were previously using SCM_CONST_LONG macro).
3228 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3230 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3231 include "fports.h" and <stdio.h>
3232 (scm_stat, scm_select): don't support FD objects.
3234 * error.h: adjust scm_syserror_msg prototype.
3235 * error.c (scm_syserror_msg): take an extra argument for errno.
3236 Using the global value didn't always work, since it could be
3237 reset by procedure calls in the message or args arguments.
3239 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3240 I don't understand why the check was there (and what about the
3243 * strop.c (scm_string_copy): allow shared substrings to be copied.
3245 * unif.h: corresponding change to prototypes.
3246 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3247 recognize two new optional arguments: offset and length. Allow
3248 the port argument to be an integer (file descriptor, for scsh).
3249 Include <unistd.h> for "read" prototype.
3251 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3253 * socket.c: don't include filesys.h.
3255 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3257 * Makefile.am: add AWK=@AWK@ (?)
3259 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3261 Add a rule to generate errnos.c from errnos.
3262 * error.c (scm_init_error): include errnos.c.
3263 * errnos_cnvt.awk: new file, converts the list of errno codes to
3265 * errnos_get.c: new file.
3266 * errnos.default: new file, contains errnos to try if they can't
3267 be extracted from errno.h.
3268 * configure.in: if using GCC, try and extract errno codes from
3272 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3274 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3275 * Makefile.am: Made libguile into a libtool library.
3276 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3277 Set libtool_libs to indicate that libguile is a libtool library.
3278 See guile/ChangeLog for details.
3279 * .cvsignore: ignore "*.lo", the libtool library objects.
3281 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3283 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3284 use htons in getservbyport argument.
3286 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3288 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3289 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3292 * objprop.c (scm_object_property): No need to take the CDR of the
3293 value returned by scm_object_properties, since Aug 20 change.
3295 * configure.in: When checking for struct linger, #include
3296 <sys/types.h> as well as <sys/socket.h>. I've never known
3297 <sys/types.h> to cause any portability problems, and Solaris's
3298 <sys/socket.h> needs it.
3299 * configure: Rebuilt.
3301 I think the Sun compiler has chosen a perverse way to interpret
3302 ANSI declarations combined with K&R definitions. We'll
3303 appease it a little bit. But when it invades France, we fight.
3304 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3305 * print.h (scm_iprlist): Here too.
3306 * numbers.c (scm_divbigdig): Change definition to match
3307 declaration in numbers.h.
3308 * unif.c (scm_makflo): Change definition to match declaration in
3311 * init.c (scm_boot_guile): Don't return the value of
3312 scm_boot_guile_1. This function doesn't return a value;
3313 scm_boot_guile_1 doesn't return a value (or return at all).
3315 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3318 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3319 compile. I have a feeling this function is a bad idea anyway ---
3320 one should always test for features, not systems.
3322 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3323 semicolons. Only pure luck kept this from being noticed earlier.
3325 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3327 * socket.c (scm_recvfrom): Added missing semicolon.
3329 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3331 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3332 the buffer and start and end positions for scsh networking
3335 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3337 * configure.in: Revert previous change to this file; the problem
3338 is due to transient automake weirdness.
3339 * configure: Rebuilt.
3341 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3342 PLUGIN/guile.libs. configure generates the latter from the former.
3343 * Makefile.in: Rebuilt.
3345 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3346 need this if we install scripts, like guile-snarf.
3347 * configure: Rebuilt.
3349 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3351 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3353 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3355 * socket.c (scm_addr_vector): fix faulty scm_listify.
3357 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3359 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3360 style block comment is no longer considered an error.
3362 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3364 * PLUGIN/guile.libs.in: New file.
3365 * PLUGIN/guile.libs: Removed from repository.
3366 * configure.in: Create PLUGIN/guile.libs from
3367 PLUGIN/guile.libs.in. This is for including additonal libraries
3368 needed for dynamic linking.
3369 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3370 instead of PLUGIN/guile.libs.
3372 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3374 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3376 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3377 occurrences of the given element from the list, not just the
3378 first. This is how the Emacs Lisp functions behave, how the
3379 analogous Common Lisp functions behave, and (I believe) how the
3380 older Maclisp functions worked. I realize that this change may
3381 break code, but it seemed better to break it before the Guile
3384 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3385 Their prototypes were already present in gc.h, but they weren't
3387 (scm_init_storage): Initialize scm_protects.
3388 * root.c (scm_protects): New element of scm_sys_protects.
3390 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3392 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3394 * libguile.h: Added #include "libguile/net_db.h".
3396 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3397 30 change. That file is only meant for communication between the
3398 configuration process and load.c. If code linked against libguile
3399 wants to get at the paths mentioned in libpath.h, it can call
3400 functions declared in load.h.
3402 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3404 * libguile.h: Removed #include "libguile/fdsocket.h"
3406 * net_db.c: Added #include <sys/socket.h>.
3408 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3410 * filesys.c (scm_input_waiting_p): use select in preference to
3411 FIONREAD, since the latter doesn't detect EOF.
3412 Throw error if neither select nor FIONREAD available.
3414 * socket.c (scm_connect): take a port, not a fd object.
3415 (scm_fill_sockaddr): throw an error if fam is not recognised.
3416 (scm_bind): use scm_fill_sockaddr.
3417 (scm_listen): take a port, not a fd object.
3418 (scm_accept): take and return a port. return #f in the car if
3419 address can't be got
3420 (scm_sock_fd_to_port): new procedure.
3421 (scm_socket): use scm_sock_fd_to_port.
3422 (scm_addr_vector): throw error if unrecognised address type.
3423 take an extra argument with the calling procedure name.
3424 (scm_getsockname): take a port. return #f if address can't be got.
3425 (scm_getpeername): take a port. return #f if address can't be got.
3426 (scm_recvfrom): take a port. return #f for address component if can't
3428 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3429 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3431 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3433 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3434 use separate data pointers, to allow them to be designed
3435 independently and reused.
3436 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3437 Renamed from catch_body, catch_handler, and uncaught_throw; made
3439 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3441 (scm_catch): Use the above.
3442 (scm_throw): Don't bother printing a message for an uncaught
3443 throw; we establish a default handler in init.
3444 * throw.h (scm_internal_catch): Prototype updated.
3445 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3447 (struct scm_body_thunk_data): New structure, used as data
3448 argument to scm_body_thunk.
3449 * init.c (struct main_func_closure): New structure, packaging up
3450 the data to pass to the user's main function.
3451 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3452 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3453 scm_internal_catch to establish a catch-all handler, using
3454 scm_handle_by_message. This replaces the special-case code in
3456 (invoke_main_func): Body function for scm_internal_catch; invoke
3457 the user's main function, using the main_func_closure pointer to
3458 decide what to pass it.
3459 * root.c (struct cwdr_body_data): Remove handler_proc member.
3460 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3461 (cwdr_handler): Removed.
3463 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3465 * socket.h (SCM_P): update bind prototype.
3466 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3467 include "feature.h".
3468 (scm_socket): return a port, not a file descriptor object.
3469 include "fports.h" and <unistd.h>
3470 (scm_bind): take a port, not a file descriptor object.
3471 take an extra argument for address args.
3473 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3474 INADDR_NONE, INADDR_LOOPBACK.
3476 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3478 * init.c: include net_db.h and not fdsocket.h.
3479 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3481 * Makefile.am: corresponding changes.
3482 * socket.h: renamed from fdsocket.h, fix names.
3483 * net_db.h: renamed from socket.h, fix names.
3484 * socket.c: renamed from fdsocket.c.
3485 remove _sys from procedure names.
3486 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3487 add "socket" to features list.
3488 * net_db.c: renamed from socket.c.
3489 remove _sys from procedure names.
3490 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3491 add "net-db" to features list.
3492 include "net_db.h". don't include <sys/socket.h> or
3495 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3497 * tags.h (scm_tags): Removed comma at end of last enumerator.
3499 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3501 Don't use GCC extensions to allocate space for debugging frames.
3502 (Here he goes again! Why do we put up with this?!)
3503 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3504 an scm_debug_info structure, not an in-line array of them. Add
3505 'info' member, to say how many vect elements we've used, for eval
3507 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3508 a new variable debug_info_end to mark the end of vect, instead of
3509 the address of the 'info' pointer itself.
3510 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3511 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3512 (SCM_APPLY): Explicitly allocate space for debug.vect.
3513 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3514 * stacks.c: Adjusted for new debug frame structure.
3515 (RELOC_INFO, RELOC_FRAME): New macros.
3516 (stack_depth, read_frames): Use them, and new scm_debug_frame
3517 element 'info', instead of magically knowing that eval frames have
3518 an info pointer sitting after vect.
3519 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3521 (scm_init_stacks): Formatting tweaks.
3523 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3525 Give GCC more control flow information, so it can be sure that
3526 variables aren't used uninitialized.
3527 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3528 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3529 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3530 scm_misc_error): Tell GCC that these functions never return.
3531 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3532 out the field type, call abort if SCM_ASSERT returns, to placate
3534 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3535 scm_wta ever returns. We can't handle this case anyway, and this
3536 gives the optimizer more information.
3537 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3538 scm_wta ever returns.
3540 In some cases, the code is fine, but GCC isn't smart enough to
3541 figure that out; this usually happens when one variable is only
3542 initialized and used when a particular condition holds true, and
3543 we know that condition will never change within a given invocation
3544 of the function. In this case, we simply initialize the variables
3545 to placate the compiler, hopefully to a value which will cause a
3546 crash if it is ever actually used.
3547 * print.c (scm_iprin1): Initialize mw_pos.
3548 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3549 * throw.c (scm_ithrow): Initialize dynpair.
3550 * unif.c (scm_uniform_vector_ref): Initialize cra.
3551 * struct.c (init_struct): Initialize prot.
3552 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3554 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3555 if EXPR contains no expressions.
3557 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3559 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3560 cause an infinite loop (???). So much for the algebraic
3561 equivalency of variable-sized arrays and alloca...
3563 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3565 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3566 a SCM boolean, not a C boolean.
3568 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3570 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3571 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3572 rules for raising scm_mtrigger. Previously, unfortunate but not
3573 unlikely circumstances could result in almost constant invokation
3574 of the gc. Now, this situations should be less likely, but they
3575 are not prevented completely.
3577 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3579 * numbers.c (scm_fuck): Procedure removed; looks like old test
3581 * numbers.h: Prototype removed.
3583 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3585 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3586 array to a pointer, to match my Nov 21 change in eval.c.
3588 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3590 * libguile.h: Added #include "libguile/backtrace.h", #include
3591 "libguile/stacks.h".
3593 * strings.c (scm_string scm_make_string scm_string_ref
3594 scm_string_set_x scm_string_equal_p scm_string_append):
3595 Bugfix according to scm patch from Aubrey Jaffer:
3596 Corrected long-standing
3597 (not (eqv? (integer->char 128)
3598 (string-ref (make-string 1 (integer->char 128)) 0)))
3599 bug found by John Kozak <jk@noontide.demon.co.uk>.
3601 * strports.c, strports.h: Make scm_eval_0str return the value of
3602 the last expression evaluated (previously, it returned void).
3604 * strports.c, strports.h: New function: scm_read_0str. Does what
3607 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3609 * simpos.c (scm_getenv): return #f if string can't be found in the
3610 environment instead of throwing an exception, for compatibility
3611 with numerous other systems.
3613 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3615 * Makefile.am (.c.x): Use guile-snarf.
3616 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3618 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3620 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3622 * backtrace.c (scm_display_error_message): Made non-static, and
3623 renamed from display_error_message.
3624 * backtrace.h (scm_display_error_message): Added extern decl.
3625 * throw.c (uncaught_throw): Use it to display the error message.
3627 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3629 * inet_aton.c: Use #if 0, not #ifdef 0.
3631 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3633 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3634 to convert the returned value.
3635 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3636 the offset argument.
3638 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3640 Add new interface to catch/throw, usable from C as well as
3642 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3643 (scm_internal_catch): New function, replaces...
3644 (scm_catch_apply): Deleted.
3645 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3646 mechanism which is a bit more code, but can be used nicely from C
3647 and implement the Scheme semantics as well.
3648 (scm_internal_catch): This is the replacement; it's named after
3649 the analogous function in Emacs.
3650 (scm_catch): Reimplemented in terms of the above.
3651 (struct catch_body_data, catch_body, catch_handler): New
3652 functions, used by scm_catch.
3653 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3654 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3655 support for new cwdr.
3657 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3660 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3662 * acconfig.h: Added DYNAMIC_LINKING symbol.
3663 * configure.in: Add option and checks for dynamic linking.
3664 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3665 dynl.h: New files for dynamic linking support.
3666 * Makefile.am (libguile_a_SOURCES):
3668 (modinclude_HEADERS): Added "dynl.h".
3669 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3671 * init.c (scm_boot_guile_1): Call
3672 scm_init_dynamic_linking to initialize dynamic linking support.
3674 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3676 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3677 (as we Schemers say). It needs to be global, so that I can tweak
3678 it for the proper operation of unexec.
3679 (scm_boot_guile_1_live): New variable, see above.
3681 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3683 * guile-snarf.sh: Removed.
3684 * PLUGIN/guile.libs: Added dependency for -lm.
3685 * acinclude.m4: Renamed from aclocal.m4.
3686 * PLUGIN/greet: Removed.
3687 * Makefile.am, aclocal.m4: New files.
3688 * configure.in: Updated for Automake.
3690 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3692 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3693 and not top_level_lookup_thunk_var.
3695 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3697 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3699 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3701 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3702 Scheme function, instead of syntax. Single argument is now a
3705 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3707 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3708 scm_ra_divide): Properly terminate statements passed as arguments
3709 to IVDEP macros. (Thanks to Bernard Urban.)
3711 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3712 with non-constant sizes. (Thanks to Bernard Urban.)
3714 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3716 It's an "eval closure", not an "eval thunk." A thunk is a
3717 function of no arguments.
3718 * root.h (struct scm_root_state): Renamed
3719 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3720 (scm_top_level_lookup_closure_var): Renamed from
3721 scm_top_level_lookup_thunk_var.
3722 * root.c (mark_root): Uses changed.
3723 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3724 * init.c (scm_start_stack): Uses changed.
3725 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3726 Change scheme-visible name to *top-level-lookup-closure* from
3727 *top-level-lookup-thunk*.
3729 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3731 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3732 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3734 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3736 * gc.c (struct scm_heap_seg_data): Doc fixes.
3738 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3739 sweeping. Then, prepend each segment's free cells to its
3740 freelist, rather than wiping out the old value. (Thanks to Marius
3743 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3744 scm_check_freelist, scm_debug_newcell): New functions and
3745 variables, for debugging freelist problems.
3746 * pairs.h (SCM_NEWCELL): New debugging version added.
3747 * gc.h (scm_debug_newcell): Added extern declaration, used by
3748 debugging version of SCM_NEWCELL.
3750 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3752 On some systems <libc.h> conflicts with <unistd.h>, and should not
3753 be #included at all.
3754 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3755 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3756 * configure.in: Call it.
3757 * posix.c, filesys.c: Use its results to decide whether or not to
3759 * configure, scmconfig.h.in: Rebuilt with autoconf and
3762 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3764 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3765 pointer to the stdio stream before calling scm_setbuf0, so the
3766 latter will be able to retrieve it. I'm surprised this didn't
3767 segfault earlier. (Thanks to Christopher Lee.)
3769 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3771 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3774 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3776 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3777 number of stack narrowing specifier pairs. The first specifier in
3778 a pair controls inner border, the second the outer border. A
3779 number means cut that number of frames, a procedure object means
3780 cut until that object is found in operator position in a frame.
3782 * root.c (cwdr): Bugfix.
3784 * read.c: Recording of positions disabled by default.
3786 * procs.c (scm_closure_p): New function.
3788 * posix.c (scm_tmpnam): New function.
3790 * load.c: Added #include "throw.h".
3791 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3794 * load.c, load.h (scm_read_and_eval_x): New function.
3796 * eval.c: Renamed debug option "deval" to "debug".
3798 (scm_eval_x): `eval!' is no longer accessible from the scheme
3799 level. Motivation: We can't allow operations which introduce
3800 glocs into the scheme level. Guile's type system can't handle
3801 these as data. Use `eval' or `read-and-eval!' as replacement.
3803 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
3804 SCM_CONSP since this is a macro!; Set vframe.prev to
3805 scm_last_debug_frame instead of 0. In this way we can look
3806 "above" the virtual start stack frame if we wish.
3807 (scm_debug_hang): New function: Useful for debugging Guile in
3808 certain tricky situations. Will probably be removed later...
3810 * debug.h: Changed semantics of debug option "backtrace". This
3811 option now only indicates whether we want automatic backtrace at
3814 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3816 * ports.c: #include "filesys.h"
3817 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
3819 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
3820 Motivation: This is system specific code which is related to file
3821 I/O. It also may use select. Added code by Gary Houston to
3822 detect presence of character in stdio buffers.
3824 * libguile.h: #include "libguile/libpath.h"
3826 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
3827 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
3828 SCM_SITE_DIR; Install libpath.h among the other include files.
3830 * load.c, load.h (scm_sys_package_data_dir): New function.
3832 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3834 * stacks.h: Bugfix: Don't use tail-array length field as stack
3835 length field! This screwed GC.
3837 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3839 * _scm.h: Added #ifndef around definition of macros min and max.
3841 * __scm.h: Added hooks for threads to plugin to in ints protection
3842 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
3843 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
3844 the main code in these macros duplicated and spread over multiple
3845 files. Renamed SCM_THREADS_SWITCHING_CODE ->
3846 SCM_THREAD_SWITCHING_CODE.
3848 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
3850 * snarf.h: New file.
3851 * guile-snarf.sh: New file.
3852 * Makefile.in (inner_h_files): Added snarf.h
3853 (ancillary, install, uninstall, distclean): Added actions for
3855 (.c.x): Use guile-snarf.
3856 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
3857 (gen_c_files): Note that these depend on guile-snarf.
3858 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
3859 now in "snarf.h". Added #include "snarf.h" to get them.
3860 * libguile.h: Added #include "snarf.h".
3861 (Patches applied and tweaked by Jim Blandy.)
3863 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3865 * socket.c: Use K&R style declaration for 'close'; the GNU coding
3866 standards suggest against providing prototypes for system
3867 functions. Thanks to Greg Troxel.
3869 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3871 * strports.c (scm_eval_0str): New function.
3872 #include "read.h", to get prototype for scm_read.
3873 * Makefile.in (strports.o): Update dependencies.
3874 * strports.h: New prototype.
3876 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
3877 scheme name from "int?" to "integer?". It seems to do the job.
3878 * numbers.h: Rename prototype too.
3879 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
3882 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
3883 scm_num_eq_p): Rename these according to R4RS conventions: call
3884 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
3885 to making libguile R4RS compliant without ice-9...
3887 * load.c (scm_sys_search_load_path): Search for files under all
3888 extensions listed in the %load-extensions variable. If FILENAME
3889 is absolute, return it unchanged, without searching the load path.
3890 (scm_loc_load_extensions): New variable, pointing to
3891 %load-extensions' value cell.
3892 (scm_init_load): Initialize it, and the value it points to.
3893 (scm_primitive_load_path): Improve error reporting.
3895 * load.c (scm_loc_load_hook): New variable, pointing to value cell
3896 of new Scheme variable %load-hook.
3897 (scm_primitive_load): Apply %load-hook to filename.
3899 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
3901 * configure.in: add tests for figuring out whether buffered data
3902 is available in a FILE structure, which is needed by char-ready.
3904 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
3907 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
3908 exceptions using misc_error instead of syserror. It seems a bit
3909 odd to throw an exception if a string can't be found in the
3910 environment, but it's consistent with open-file, stat etc.
3911 (simpos.h): remove sys_ from getenv.
3913 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
3914 occurs, throw an error instead of returning errno. Return value
3916 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
3918 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
3920 * filesys.c (scm_stat2scm): derive file type and permissions from
3921 the stat mode and append them to the returned vector.
3922 There isn't much overhead in doing this and it avoids the need to
3923 work with S_IRUSR et al. in Scheme.
3924 Define symbols scm_sym_regular etc.
3925 (scm_init_filesys): don't intern S_IRUSR etc.
3927 * load.c: change s_try_load and s_try_load_path to s_primitive_load
3928 and s_primitive_load_path.
3930 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
3932 * error.h: don't declare error symbols. prototype for scm_misc_error.
3934 * stackchk.c (scm_stack_overflow_key): defined here instead of in
3937 * error.c: use SCM_SYMBOL to set up error keys.
3938 scm_misc_error: new procedure.
3940 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3942 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
3943 between `#!' and `!#' is ignored.
3944 (skip_scsh_block_comment): New function.
3946 * feature.c (scm_set_program_arguments): New argument, FIRST.
3947 * feature.h: Update prototype.
3948 * init.c (scm_boot_guile_1): Pass new argument to
3949 scm_set_program_arguments.
3951 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3953 * init.c (scm_start_stack): Don't initialize scm_progargs here.
3954 (scm_boot_guile): Call scm_set_program_arguments here, later than
3955 the old initialization.
3957 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
3958 initialization procedure.
3959 - Delete in, out, err arguments; there are other perfectly good
3960 ways to override these when desired.
3961 - Delete result argument; this function shouldn't ever return.
3962 - Rename init_func argument to main_func, for less confusion.
3963 - Delete boot_cmd argument; main_func is more general.
3964 -Add 'closure' argument, to help people pass data to main_func
3965 without resorting to global variables.
3966 - Abort if reentered; don't bother returning an error code.
3967 - Call scm_init_standard_ports to set up the default/current
3968 standard ports; no need to pass them to scm_start_stack.
3969 - Remove code to evaluate the boot_cmd, and start the repl; let
3970 the user do something like that in main_func if they want.
3971 - Remove code to package up a return value; main_func can do any
3973 - Call exit (0), instead of returning.
3974 (scm_start_stack): Don't initialize the I/O ports here; that's
3975 weird. Delete in, out, err arguments. Move guts to
3976 scm_init_standard_ports, scm_stdio_to_port.
3977 (scm_init_standard_ports): New function, to set up current and
3978 default standard ports.
3979 (scm_start_stack, scm_restart_stack): Make these static.
3980 * init.h (scm_boot_guile): Adjust declaration.
3981 (scm_start_stack, scm_restart_stack): Remove externally
3982 visible declarations for these.
3983 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
3985 * fports.c (scm_stdio_to_port): New function. Its guts used to be
3986 written out several times in scm_start_stack.
3987 * fports.h: New declaration for the above.
3989 * feature.c (scm_set_program_arguments): New function.
3990 * feature.h: New declaration for the above.
3992 * ports.c: Formatting tweak.
3994 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
3996 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
3997 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
3998 for obtaining the address of a car or cdr field. Motivation:
3999 &SCM_CXR make assumptions about the internal structure of the
4002 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4003 Motivation: see SCM_CXRLOC.
4005 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4006 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4007 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4008 Motivation: Safer use. Some other macros are defined in terms of
4009 these operations. If these are defined using the SCM_SETCXR
4010 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4011 to inefficiency and an <e1> with side-effects could potentially
4012 break. Also, these particular operations are heavily utilized in
4013 the garbage collector. In unoptimized code there will be a
4016 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4017 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4018 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4019 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4020 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4021 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4022 vports.c: Cleaned up use of pairs: Don't make any special
4023 assumptions about the internal structure of selectors and
4024 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4025 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4026 (Among other things, this change makes it easier to build Guile
4027 with certain compilers which have problems with casted lvalues.)
4029 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4031 * stacks.c: Improve selection of relevant stack frames when making
4032 a stack object. Introduce one level of indirection in the stack
4033 object to make it possible to "narrow" to a certain region of the
4034 stack. This facilitates making use of more clever algorithms (not
4035 implemented) for selecting relevant frames and gives a cleaner
4036 design since selection of frames can be done independently of
4037 extraction of frames from the real stack.
4038 (scm_stack_id): Also take #t as argument which means look at
4041 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4042 Turn n_tail into an integer directly representing current number
4043 of frames in stack. Add field tail.
4045 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4047 * debug.c (scm_make_memoized): Made it available at scheme level.
4048 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4049 SCM_NIMP before applying heavier predicates in argument checking.
4050 (scm_local_eval): Also take memoized object as argument.
4052 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4053 aren't created with zero length, but should such a strange
4054 creature suddenly turn up...
4056 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4058 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4059 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4061 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4063 * variable.c (scm_make_variable): Make the name hint optional, as
4065 (anonymous_variable_sym): Renamed from variable_sym. All uses
4068 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4069 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4070 of scm_primitive_load_path was also changed to
4071 "primitive-load-path", from "%try-load-path". Callers changed.
4072 We'd like to respect the convention that a function named
4073 "try-mumble" should behave just like the function called "mumble",
4074 but return #f instead of signalling some error.
4075 * load.h: Rename prototypes.
4077 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4079 * print.c (make_print_state, grow_print_state), print.h: Modified
4080 the print state representation: Don't use a tail array for
4081 recording of circular references. Resizing of the print state
4082 structure invalidates the print state pointer. To avoid passing
4083 around an indirect print state reference to all printing
4084 functions, we instead let the print state reference a resizable
4087 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4089 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4090 Don't crash when passed an improper list terminated by a
4091 non-immediate value.
4093 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4095 Allocate data for structures on an eight-byte boundary, as
4096 required by the tagging system.
4097 * struct.c (alloc_struct): New function.
4098 (scm_make_struct, scm_make_vtable_vtable): Call it.
4099 * struct.h (scm_struct_n_extra_words): Bump to 3.
4100 (scm_struct_i_ptr): New "field".
4101 * gc.c (scm_gc_sweep): When we need to free the data, use the
4102 information stored by alloc_struct to find the beginning of the
4103 block allocated to the structure, so we can free it.
4105 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4107 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4110 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4111 (scm_debug_info): New member: id.
4113 * stacks.c: Stacks are now represented as structs; Stacks have an
4114 id given to them by `start-stack'.
4115 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4117 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4118 Changed stack representation.
4120 * debug.c (scm_procedure_name): Try procedure property `name' for
4121 compiled closures aswell.
4123 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4125 * eval.c: scm_i_name moved to gsubr.c
4126 (scm_m_define): Record names of all kinds of procedure
4127 objects. (Earlier, only closures were recorded.)
4129 * procprop.h: Added declaration of scm_i_name.
4131 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4132 (scm_make_gsubr): Record names of compiled closures.
4134 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4136 * debug.c, debug.h: Removed obsolete code.
4138 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4139 stacks.c: Renamed regs --> scm_contregs.
4141 * print.c (scm_free_print_state): Cleanup print state before
4142 returning it to pool. It is better to do it here than in
4143 scm_prin1 since scm_prin1 is called often.
4145 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4146 s_set_source_property_x): Check that first argument is a pair or a
4149 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4150 scm_i_line, scm_i_column and scm_i_breakpoint global.
4152 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4153 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4156 * debug.h: Added debug object smob declaration and macro
4159 * configure.in: Build with backtrace.o and stacks.o if debug
4162 * Makefile.in: Added entries for new files: backtrace.c,
4163 backtrace.h, stacks.c and stacks.h.
4165 * symbols.c (scm_sym2ovcell): Fixed documentation.
4167 * _scm.h (min, max): Added.
4169 * async.c: Moved `min' macro to _scm.h.
4171 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4172 SCM_BACKTRACE_INDENT.
4174 * eval.c: Added new debug options `maxdepth' and `indent'.
4176 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4178 * print.h: Added selector SCM_PRINT_STATE.
4180 * print.c: New functions: scm_make_print_state,
4181 scm_free_print_state.
4183 * print.h: Added declarations for scm_make_print_state,
4184 scm_free_print_state.
4186 * debug.c (scm_m_start_stack): New acro.
4188 * debug.h: Small cleanup.
4190 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4193 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4213 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
4214 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
4215 declare functions with prototypes. (Patch thanks to Marius
4218 More prototype-related changes from Marius Vollmer:
4219 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4220 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4221 * ports.h (ptobfuns): Added prototypes. This means some casting in
4223 * fports.c: Added casts for initializations, since the functions
4224 are defined to take FILE * as their stream argument, not SCM.
4225 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4226 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4227 to `char *str_data' to conform to prototype.
4229 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4231 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4233 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4235 * stime.c, stime.h: use SCM_P method.
4237 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4239 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4240 be given at least two arguments. Insist that lst's last element
4241 be a list, but don't make any requirements of its predecessors.
4243 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4245 * eval.c (scm_nconc2last): Revert last change; there seems to be
4246 other stuff going on here.
4248 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4250 * eval.c (scm_nconc2last): Make sure that each element of lst
4251 (which is a list of argument lists, except for the tail) is a
4252 proper list, i.e., finite and terminated by '().
4254 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4256 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4259 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4260 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4263 * vectors.c (scm_make_vector): Fill vectors with the undefined
4264 value, to help make Guile Scheme code more portable to other
4267 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4268 * symbols.h, tags.h: Doc fixes.
4270 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4272 * async.c (scm_take_signal): Doc fixes.
4274 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4276 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4277 want to subtract it from the modulus; we just want to leave it
4280 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4282 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4285 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4287 * throw.c (scm_catch_apply): Finished implementation of
4290 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4292 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4294 (scm_init_filesys): set "i/o-extensions" feature.
4297 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4299 * Makefile.in (root.o): Correct dependencies.
4301 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4303 * Makefile.in: Added dependency entry for root.o.
4305 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4306 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4308 * init.c (scm_start_stack): Set initial root continuation number
4311 * procs.c: New function: scm_thunk_p.
4313 * procs.h: Added declarations of scm_thunk_p.
4315 * root.c: Renamed `call-with-new-root' -->
4316 `call-with-dynamic-root'.
4317 (cwdr): Removed allocation of new root state. This should be done
4318 separately by use of scm_make_root.
4319 (scm_apply_with_dynamic_root): New function: Does what it
4320 sounds like. Needed when spawning threads.
4322 * root.h: Added member last_debug_frame to root state.
4323 Added #include "libguile/debug.h"
4325 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4326 arguments. The motivation is that code in root.c needs catch
4327 functionality, and we want to avoid code duplication.
4328 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4329 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4330 handlers that run without popping the stack into the dynwind
4333 * throw.h: Added prototypes for scm_catch_apply and
4336 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4338 * root.h (scm_root, scm_set_root): Decouple thread support details
4339 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4340 SCM_SET_THREAD_LOCAL_DATA.
4342 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4343 and tortoise scanning loop.
4345 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4347 * Makefile.in: Rebuild dependencies.
4349 * libguile.h: #include "libguile/print.h" before "smob.h", since
4350 the latter uses the print_state structure.
4352 * throw.c (scm_ithrow): Use the correct variable when checking to
4353 see if a given element of scm_dynwinds is a valid catch.
4355 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4356 structure, abort; don't just silently ignore the garbage.
4358 * _scm.h: #include "print.h" here, since it seems to be used just
4360 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4361 strports.c, unif.h: Don't #include "print.h".
4363 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4365 * feature.h (scm_loc_features): Removed external declaration.
4366 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4368 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4370 * feature.c (scm_init_feature): Added threads feature (needs to be
4371 initialized here, since features doesn't exist when
4372 scm_init_threads is called).
4374 * libguile.h: Added #include "libguile/../threads/threads.h".
4375 (This is a kludge to get thread support working. This should be
4378 * configure.in, acconfig.h: Added flags for thread support.
4380 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4383 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4384 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4387 * _scm.h: Added conditional #include "threads.h"
4389 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4390 SCM_THREADS_SWITCHING_CODE.
4392 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4393 allocate the basic dynamic root object.
4394 (scm_boot_guile): Added call to scm_init_root.
4396 * root.c, root.h: Added root smob.
4397 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4398 functions: Implements dynamic roots mostly according to spec in
4399 SCM manual. Main difference is that the second argument is a
4400 throw handler rather than an error "thunk".
4402 * root.h: Added declaration of scm_init_root.
4404 * root.c: Added #include "genio.h", #include "smob.h", #include
4405 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4407 (scm_init_root): Added #include "root.x".
4409 * throw.c: Added #include "stackchk.h"
4410 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4411 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4412 can be used in scm_call_with_new_root; Added reenabling of stack
4413 checking when catching a throw.
4415 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4417 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4419 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4420 element is not found, as per R4RS.
4422 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4424 * list.c: Doc fixes throughout.
4426 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4428 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4429 declare the char * to be const. Avoids a warning in rgx.c.
4431 * ports.h: spelling fix.
4433 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4436 * load.c (scm_sys_try_load_path): throw an error if file not found
4437 (like it says it in NEWS).
4439 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4441 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4442 PROPS slot to '(), not #f; it's an empty alist.
4444 * throw.h, throw.c: Use SCM_P instead of #if hair.
4446 Remove special support for uncaught throws; see throw.c for
4448 * throw.c (uncaught_throw): New function.
4449 (scm_ithrow): Call uncaught_throw if we don't find a throw
4450 target; don't mess with scm_bad_throw_vcell.
4451 (scm_bad_throw_vcell): Variable deleted.
4452 (scm_init_throw): Don't initialize it.
4454 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4457 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4459 * numbers.c (scm_istr2int): If the number is short (as most
4460 numbers are), just call scm_small_istr2int to deal with it.
4461 (scm_small_istr2int): New function, created by un-#ifdefing the
4462 non-bignum version of scm_istr2int and renaming it.
4464 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4466 * load.c (scm_sys_try_load): don't check whether value returned
4467 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4468 Change the Scheme name from %try-load to primitive-load.
4470 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4471 Can avoid passing a message, allowing it to be derived in the
4472 error handler (e.g., if we want to throw to the key both from
4475 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4477 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4478 references now have a new appearance which is more compact and
4479 also gives a clue about what the target of the reference is.
4480 By setting parameters in the print state, more fancy printing can
4481 be achieved. This is used by the (not yet commited) backtrace
4484 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4486 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4489 * print.c: Added #include "struct.h". Removed function
4492 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4493 scm_iprin1. Removed prototype for scm_prlist.
4495 * arbiters.c (prinarb),
4496 async.c (print_async),
4497 debug.c (prindebugobj, prinmemoized),
4498 eval.c (prinprom, prinmacro),
4499 filesys.c (scm_fd_print, scm_dir_print),
4501 mallocs.c (prinmalloc),
4502 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4503 smob.h (scm_smobfuns),
4504 srcprop.c (prinsrcprops),
4506 unif.c, unif.h (scm_raprin1, rapr1),
4507 variable.c (prin_var): Changed argument `int writing' to
4508 `scm_print_state *pstate'.
4510 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4511 that it will be called before scm_init_print.
4513 * print.c (scm_prin1): Print states are now allocated when calling
4514 scm_prin1 and then passed around to all printing functions as an
4515 argument. A cache `print_state_pool' enables reuse of print
4517 (scm_make_print_state): New function.
4518 (scm_iprin1): Adaption to print states.
4519 (scm_iprlist): An initial "hare and tortoise" scan brings down
4520 time complexity to O (depth * N). (Better time complexity will be
4521 achieved when the printing code is completely rewritten.)
4523 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4525 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4526 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4527 it gets done whether or not the cache variable has a value.
4529 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4531 Distinguish #f and ().
4532 * __scm.h: #undef SICP.
4533 * pairs.h (SCM_EOL): Delete this definition, equating it with
4535 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4536 the value it used to have. Doc fixes, too.
4538 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4540 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4541 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4542 Lord's implementation of structs, allowing for tail arrays as
4543 described in the manual. Also fixed some bugs. (Both the interface
4544 and the implementation should be improved.)
4546 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4548 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4549 People who whish to see the source can do `(print-enable 'source)'.
4550 Removed #ifdef DEBUG_EXTENSIONS.
4552 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4554 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4555 integer (assuming for now accepting an integer is a good thing).
4557 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4558 %S will be used instead for write'ing arguments.
4560 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4561 asserts. fix a few other asserts.
4562 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4563 scm_uniform_vector_ref, scm_array_set_x,
4564 scm_dimensions_to_unform_array): change args in
4565 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4566 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4567 scm_substring_fill_x): likewise.
4568 gsubr.c (scm_gsubr_apply): likewise.
4569 eval.c (SCM_APPLY): likewise.
4571 * eval.c (4 places): replace scm_everr with lgh_error or
4574 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4575 scm_memory_error): new procedures.
4576 scm_everr: deleted. can use scm_wta, dropping first two args.
4577 scm_error: convert NULL subr to SCM_BOOL_F.
4579 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4582 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4585 * error.c, error.h: new error keys: scm_arg_type_key,
4586 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4588 scm_wta: reimplement using lgh_error instead of scm_everr.
4590 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4592 * gdbint.c: scm_lread now has one more argument.
4594 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4595 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4596 loading source from non-file ports, which, e. g., happens when
4597 using the Emacs interface).
4599 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4602 * read.c: Added code for recording of positions of source code
4603 expressions; New functions: recsexpr, scm_lreadrecparen;
4604 _scm_make_srcprops --> scm_make_srcprops
4605 (scm_flush_ws): Removed updating of positions counters. This work
4606 is already done by scm_gen_getc
4608 * read.h: Added prototype for scm_lreadrecparen
4610 * print.c: Added #include "alist.h"
4612 * eval.c: Added #include "hash.h"
4614 * eq.c: Added #include "ramap.h"
4616 * options.c: Documentation fixes.
4618 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4619 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4620 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4621 --> scm_make_srcprops
4623 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4624 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4625 function calls in the definition of the whash access macros.
4627 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4629 * init.c (scm_boot_guile): Add level of indirection to
4630 scm_boot_guile_1() to ensure that stack base pointer is properly
4631 initialized. There was no guarantee that variable i was the
4632 highest/lowest variable on stack (i.e. the call frame of
4633 scm_boot_guile was not completely protected from gc).
4635 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4637 * ports.h (scm_port_table): put back file_name, it will be used to
4638 support debugging. Undo related changes in fports.c, ioext.c,
4641 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4643 * ports.h (scm_port_table): remove file_name member for now, it seems
4645 * fports.c (scm_open_file): don't set file_name in PTAB.
4646 (prinfport): don't use file_name in PTAB.
4647 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4648 * ports.c (scm_add_to_port_table): don't intialize file_name.
4649 (scm_port_file_name): remove for now.
4650 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4652 * fports.h (scm_mkfile): prototype deleted.
4653 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4655 * debug.c, unif.c: use scm_out_of_range instead of
4656 wta for range errors (ASSERT still needs work).
4658 * error.c, error.h (scm_out_of_range): new procedure.
4660 * error.c, error.h (scm_out_of_range_key): new key.
4662 * posix.c (scm_sync): #else was missing.
4664 * error.c, error.h: append _key to names scm_num_overflow and
4667 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4668 of consing an empty list.
4669 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4670 of macros, saves code and string space.
4671 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4672 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4673 lower case. Rename scm_syserror_m to scm_syserror_msg.
4674 error.h: prototypes for new procedures.
4676 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4678 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4680 * error.c, error.h: setup scm_num_overflow key.
4682 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4683 Remove definition of SCM_OVSCM_FLOW.
4685 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4687 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4688 explicit message and args.
4690 * error.c, error.h, __scm.h: change system_error_sym to
4693 * error.c (system_error_sym): remove leading %% from the Scheme name
4696 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4698 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4700 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4701 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4702 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4703 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4704 renamed. (These were introduced by unsupervised name
4707 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4709 * print.c: Added code for detection of circular references during
4710 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4711 a hook for printing of closures (accessible via print options).
4712 This leads to a split of calls to scm_iprin1 into two classes:
4713 elementary print operations (e. g. the code which prints a smob)
4714 still use scm_iprin1 while top level calls (like scm_display) use
4715 scm_prin1. scm_prin1 begins by clearing the data structure used
4716 to record reference information.
4718 * print.h: Added declarations of scm_prin1 and scm_prlist.
4720 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4722 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4724 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4726 * error.c (err_head): scm_iprin1 --> scm_prin1
4728 * debug.c: Adjusted header comment.
4732 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4734 * strerror.c: Doc fix.
4736 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4738 * gdbint.c (gdb_read): Now possible to run during GC.
4739 (unmark_port, remark_port): New functions.
4741 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4743 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4744 of allocating a new string object. Also, increase size by
4745 the factor 2 instead of 1.5.
4747 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4749 * __scm.h (SCM_P): Corrected to run under traditional C.
4751 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4754 * async.c: Calls to scm_sysintern corrected.
4756 * async.h (scm_async_clock): Redundant declaration removed.
4758 * continuations.c (scm_dynthrow): Redundant declaration removed.
4760 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4761 Definition typos corrected.
4763 * debug.h: Missing declarations of functions in debug.c added
4766 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4767 Missing declarations to functions in eval.c added.
4769 * filesys.c: Possibly uninitialized variable rv.
4771 * gc.h (scm_object_addr, scm_unhash_name): Missing
4772 declarations of functions defined in gc.c added.
4774 * genio.c: Possible typos str_data -> wstr_data. ???
4776 * genio.c: Possibly unintended shadowing of local variable
4777 `int c' (gotos out of scope of inner `c'). ???
4779 * init.c: Uninitialized `SCM last' may be used.
4781 * ioext.h: (scm_sys_isatty_p): Typo.
4783 * list.h (scm_list_head): Missing prototype for function in
4786 * numbers.c (scm_two_doubles): Changed from extern to static
4787 (is used only within numbers.c).
4789 * numbers.h: Repeated declarations removed.
4791 * ports.h (scm_close_all_ports_except): Declaration for the
4792 function defined in ports.c added.
4794 * posix.h: Missing declarations added.
4796 * procs.h (scm_make_subr_opt): Missing declaration added.
4798 * socket.h (scm_sys_gethost): Missing declaration added.
4800 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4802 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
4803 Missing declarations added.
4805 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
4807 * struct.c: Uninitialized variable `SCM answer' may be used.
4809 * unif.c (l2ra): Declaration prototype.
4811 * unif.c (scm_array_equal_p): Dummy definition removed (it is
4812 defined in ramap.c).
4814 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
4815 Redundant declarations removed (they are in ramap.h).
4817 * variable.h (scm_make_udvariable,
4818 scm_make_undefined_variable): Declaration corrected to
4819 correspond variable.c.
4821 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
4822 Missing declarations added.
4824 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
4826 * Makefile.in (distclean): Don't forget to delete fd.h.
4828 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4830 * fd.h.in, tags.h: Trivial cleanups.
4832 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
4833 marksweep.h just declared functions from gc.c.
4834 * gc.h, libguile.h: Don't #include "marksweep.h".
4835 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4836 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
4837 dependencies updated.
4839 * libguile.h: Don't #include "files.h"; it's been deleted.
4841 * files.c (scm_sys_delete_file): Moved to filesys.c.
4842 File is now empty; deleted.
4844 * filesys.c: scm_sys_delete_file is now here. Remove
4845 #if's; they seem to rely on remnants of an old portability
4846 regimen. If the problems come up again, solve them properly,
4847 using autoconf. Specifically: Don't test M_SYSV, and #define
4848 remove to be unlink if it's #defined; don't use remove just
4849 because HAVE_STDC_HEADERS is #defined.
4850 * filesys.h: Add declarations for scm_sys_delete_file.
4851 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4852 files.o, files.h, files.c, and files.x.
4853 * init.c: Don't #include "files.h", and don't call scm_init_files.
4855 Use SCM_P instead of PROTO; the latter intrudes on the user's
4857 * params.h: Deleted; definition of SCM_P moved to...
4858 * __scm.h: ... here, where it replaces PROTO macro.
4859 * libguile.h, smob.h: Don't #include "params.h".
4860 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
4861 smob.h: Fix prototypes accordingly.
4862 * Makefile.in: Update dependencies.
4863 (inner_h_files): Remove params.h.
4865 * gc.c: #include "gc.h"; every module should include its header,
4866 to let the compiler cross-check the declarations against the
4869 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
4870 simpos.h: #include "libguile/__scm.h".
4872 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
4874 * init.c: Don't forget to #include smob.h and init.h.
4875 * Makefile.in: Dependencies updated.
4877 * smob.h: Use PROTO instead of #if __STDC__.
4879 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
4881 * __scm.h: Doc fixes.
4883 * __scm.h, libguile.h: Use "quotes" in the #includes, not
4884 <angles>; this allows `make depends' to work properly.
4886 * libguile.h: #include smob.h and pairs.h before the others; they
4887 define typedefs used by other headers.
4889 C files should #include only the header files they need, not
4890 libguile.h (which #includes all the header files); the pointless
4891 recompilation was wasting my time.
4892 * Makefile.in (all .o dependency lists): Regenerated.
4893 * libguile.h: Don't try to get a definition for size_t here...
4894 * __scm.h: Do it here.
4895 * _scm.h: Since this is the internal libguile header, put things
4896 here that all (or a majority) of the libguile files will want.
4897 Don't #include <libguile.h> here; that generates dependencies on
4898 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
4899 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
4900 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

4997 * weaks.c: Get "weaks.h".
4999 * stackchk.h: #include "libguile/debug.h",
5001 * print.h, read.h: #include "options.h", since everyone who uses
5002 either of these files will need that.
5004 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5005 anyone who uses this file will need them to define the smob
5006 printing functions. Also, get markers.h, since people will need
5007 to #define the mark functions.
5009 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5010 * ports.h: ... to here.
5012 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5013 don't rely on archaic C default type rules.
5015 * fports.h: #include "libguile/ports.h", since you need that in
5016 order to parse this.
5018 * genio.h: #include "libguile/print.h", because you need that to
5019 parse this; don't bother #including "ports.h", since print.h gets
5022 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5024 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5025 this; it's now a reference to an element of *scm_root.
5027 * debug.h: Don't #include "options.h"; the compiler won't be able
5028 to find that once the headers are installed; instead, #include
5029 "libguile/options.h".
5030 * gc.h: Same, with marksweep.h.
5031 * mbstrings.h: Same, with symbols.h.
5032 * scmhob.h: Same, with _scm.h.
5033 * smob.h: Same, with params.h.
5035 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5036 C files; there's no need for this, and it forces recompilations
5039 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5041 * error.c (scm_error): declare scm_error_callback.
5043 * error.h: prototype for scm_error_callback.
5045 * __scm.h: define lgh_error.
5046 (SCM_SYSERROR): redefine using lgh_error.
5048 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5050 * error.c (scm_error): new procedure.
5052 * error.h: prototype for scm_error.
5054 * Makefile.in (install): install scmconfig.h from the current
5055 directory, not $(srcdir).
5057 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5059 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5060 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5061 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5062 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
5063 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
5064 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5065 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5066 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5067 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5068 vports.h, weaks.h: #include "libguile/__scm.h", not
5069 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5070 dependencies are within libguile properly.
5072 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5074 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5075 when scmconfig.h doesn't exist.
5077 * load.c (scm_sys_try_load): Correct spelling.
5079 * feature.c (scm_loc_features): Make this static.
5081 * Makefile.in (libpath.h): Omit trailing slash from path. We
5082 shouldn't require it of users, so why put it here?
5084 Move code to initialize and search %load-path from ice-9 to C
5085 code, so we can use the load-path to find the ice-9 boot code;
5086 this makes it easier to run Guile without installing it. See
5087 corresponding changes in guile/Makefile.in.
5088 * feature.c: Move stuff concerned with the load path to load.c.
5089 (scm_compiled_library_path): Deleted.
5090 Don't #include libpath.h here.
5091 * feature.h: Don't mention scm_compiled_library_path.
5092 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5093 <sys/stat.h>, and <unistd.h> (if present).
5094 (R_OK): #define if the system hasn't deigned to.
5095 (scm_loc_load_path): New variable.
5096 (scm_init_load_path, scm_sys_search_load_path,
5097 scm_sys_try_load_path): New functions.
5098 (scm_init_load): Initialize scm_loc_load_path to point to the
5099 value cell of the Scheme %load-path variable.
5100 * load.h: Add declarations for scm_sys_search_load_path,
5101 scm_sys_try_load_path.
5102 * init.c: Call scm_init_load_path.
5103 * Makefile.in (feature.o, load.o): Dependencies updated.
5105 * load.c, load.h: Rewrite using PROTO macro.
5107 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5109 * gc.c (scm_cellp): New function: C predicate to determine if an
5110 SCM value can be regarded as a pointer to a cell on the heap.
5112 * gc.h: Added declaration of scm_cellp.
5114 * gdb_interface.h: New file: The GDB interface header from the GDB
5117 * gdbint.c: New file: GDB interface.
5119 * gdbint.h: New file: GDB interface.
5121 * libguile.h: Added #include <libguile/gdbint.h>.
5123 * init.c (scm_boot_guile): Added scm_init_gdbint.
5125 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5126 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5127 found if object files and source are kept separate).
5129 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5131 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5133 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5135 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5136 TK_SRC_DIR; they're not relevant any more.
5138 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5139 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5141 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5143 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5144 search path, so we can find the <libguile/MUMBLE.h> headers.
5146 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5148 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5149 implicit in the .c.o rule.
5150 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5153 Put the library path in a header file, instead of passing it on
5154 the command line in every compilation.
5155 * Makefile.in (libpath.h): New target.
5156 (feature.o): Depend on libpath.h.
5157 (clean): Delete libpath.h.
5158 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5159 * feature.c: ... #include "libpath.h" here.
5160 * .cvsignore: Ignore libpath.h.
5162 Don't install the unwashed masses of Guile header files in the
5163 main #include path; put most of them in a subdirectory called
5164 'libguile'. This avoids naming conflicts between Guile header
5165 files and system header files (of which there were a few).
5166 * Makefile.in (pkgincludedir): Deleted.
5167 (innerincludedir): New variable; this and $(includedir) are enough.
5168 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5169 (installed_h_files): Divide this up. Now this variable lists
5170 those header files which should go into $(includedir) (i.e. appear
5171 directly in the #include path), and ...
5172 (inner_h_files): ... this new variable says which files appear in
5173 a subdirectory, and are referred to as <libguile/mumble.h>.
5174 (h_files): List them both.
5175 (install): Create innerincludedir, not pkgincludedir. Put
5176 the installed_h_files and inner_h_files in their proper places.
5177 (uninstall): Corresponding changes.
5178 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5179 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5180 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5181 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5182 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5183 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5184 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5185 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5186 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5187 vports.h, weaks.h: Find __scm.h in its new location.
5188 * __scm.h: Find scmconfig.h and tags.h in their new locations
5189 (they're both "inner" files).
5191 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5193 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5195 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5197 * posix.c: Doc fixes.
5199 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5201 * socket.c: Don't include a prototype for inet_aton; just use a
5202 K&R style declaration, to avoid warnings but minimize the chance
5203 of conflicts with the system.
5205 On NextStep, <utime.h> doesn't define struct utime, unless we
5206 #define _POSIX_SOURCE before #including it.
5207 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5208 * acconfig.h: New comment text for above CPP symbol.
5209 * configure.in: Call it.
5210 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5212 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5214 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5215 testing for __EMX__.
5217 * posix.c: #include <libc.h>, if it exists.
5219 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5220 don't even know if the latter exists.
5222 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5223 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5224 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5226 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5228 (scm_init_posix): Use them when initializing the Scheme constants
5231 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5233 * Makefile.in (libdir, includedir, bindir): Use the
5234 autoconf-supplied values, instead of deriving them ourselves.
5235 (pkgincludedir, datadir, pkgdatadir): New variables.
5236 (install, uninstall): Put the header files in a special
5237 subdirectory, not in the main search path.
5239 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5240 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5242 * Makefile.in (IMPLPATH): Deleted; never used.
5244 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5245 on the Tcl/Tk source any more.
5246 (INCLUDE_CFLAGS): Remove references to the above.
5248 * Makefile.in (version.o): Corrected dependencies.
5250 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5252 * libguile.h: #include "version.h"
5254 * init.c (scm_boot_guile): Call scm_init_version.
5255 * gscm.c (gscm_run_scm): Call scm_init_version.
5257 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5258 GUILE_VERSION): AC_DEFINE these.
5259 (acconfig.h): #undef the above symbols.
5261 * Makefile.in (libobjs): Add version.o.
5262 (installed_h_files): Add version.h.
5263 (c_files): Add version.c.
5264 (gen_c_files): Add version.x.
5265 (version.o): New rule.
5266 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5267 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5268 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,

5276 weaks.o): Add version.h to dependency lists.
5277 (markers.o): Remove duplicate rule.
5279 * version.h: New file.
5281 * version.c: New file.
5283 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5285 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5286 array; use it appropriately. Since GCC is quite happy to
5287 subscript functions, it never warned us about this; we should use
5288 -Wpointer-arith in the future. I guess we never tested
5291 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5293 * socket.c: Doc and copyright fixes.
5295 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5297 * debug.c: Fixed and improved gdb support.
5299 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5301 * socket.c: Added declaration of inet_aton to avoid compiler
5302 warning. (Hope this solution is correct.)
5304 * stime.c: Added declaration of ftime. (This is missing in
5307 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5309 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5311 * Makefile.in (c_files): add strerror.c.
5313 * strerror.c: new file from Emacs' sysdep.c.
5314 maybe configure should also check for sys_errlist.
5316 * configure.in (AC_REPLACE_FUNCS): add strerror.
5318 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5320 * debug.c (scm_init_debug): Added initialization for
5321 scm_evaluator_traps.
5323 * debug.h, debug.c: Various name changes.
5324 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5325 "debug-options-interface". See commentary in options.c.
5327 * options.h, options.c: Options now have documentation strings.
5328 Also added a long explanatory commentary.
5330 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5333 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5334 last_debug_info_frame is now updated in all cases.
5336 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5339 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5341 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5342 Added option STACK_CHECKING.
5344 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5346 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5348 * __scm.h: Removed symbols for debugging support.
5350 * acconfig.h: Added symbols for debugging support.
5352 * configure.in: Added user option for debugging support.
5353 --enable-debug will include the debugging code into libguile.a.
5355 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5356 scm_relocate_chunk_to_heap.
5358 * debug.c: New file: low-level debugging support. It also
5359 includes support for debugging with gdb. (The extensions to gdb
5360 are written by Per Bothner at Cygnus.)
5362 * debug.h: New file: low-level debugging support.
5364 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5365 argument pairs. Extensive modifications to the debugging
5366 evaluator. Added "SECTION:" commentaries to clarify what happens
5367 when, during double compilation. Renamed EVALIMP --> EVALIM.
5368 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5369 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5370 the beginning of the file. New procedure: scm_unmemocopy.
5371 Added some global state variables needed by the debugging
5372 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5373 check_entry, check_apply, check_exit, debug_options and
5374 evaluator_traps. New acro: undefine.
5376 * eval.h: Renamed EVAL --> XEVAL.
5378 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5379 --> scm_make_weak_key_hash_table.
5381 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5382 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5384 * libguile.h: Conditionally include debug.h
5386 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5387 scm_object_properties shouldn't return handle. `handle' now gets
5388 initialized in scm_set_object_properties_x. scm_object_properties
5389 doesn't any longer create an entry in scm_object_whash.
5391 * options.c: New file: handling of run time options.
5393 * options.h: New file: handling of run time options.
5395 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5397 * print.c: New procedure: scm_print_options
5399 * print.h: Defines for print options.
5401 * read.c: New procedure: scm_read_options
5403 * read.h: Defines for reader options.
5405 * root.h: Added scm_source_whash among scm_sys_protects.
5407 * srcprop.c: New file: source properties.
5409 * srcprop.h: New file: source properties.
5411 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5412 (Bug found by A. Green.)
5414 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5416 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5418 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5420 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5422 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5423 and should be called by the final client.
5425 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5427 * gc.h: Use the PROTO macro when declaring functions.
5428 * gc.c: Use the PROTO macro when declaring static functions.
5429 Remove the CPP hair around function definitions.
5431 * gc.c (scm_init_storage): Initialize scm_asyncs.
5433 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5434 preprocessor symbol; "__scm.h" is where it might get #defined.
5435 * __scm.h: Similar: #include <scmconfig.h> before testing
5438 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5440 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5442 * init.c (scm_boot_guile): Add init_func argument; call
5443 (*init_func) instead of calling scm_appinit; it's ucky to
5444 hard-code names for the user's procedures.
5445 * init.h (scm_boot_guile): Adjust declaration.
5447 * __scm.h (PROTO): New macro, for declaring functions with
5450 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5451 eliminate all the __STDC__ conditionals.
5452 (scm_boot_guile): Add declaration.
5453 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5454 Remove __STDC__ conditionals around function definitions; the
5455 declarations in init.h will provide the same information, more
5458 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5459 complain about it in the error message; the error message is
5460 adequate without that note, and there's nothing the user can do
5463 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5465 * Makefile.in (ancillary): Drop def.sed.
5467 * posix.c (scm_init_posix): Use numeric values, rather than
5468 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5469 F_OK. The symbols aren't available on some systems, and I'm
5470 pretty sure their values are fixed by common widespread practice.
5471 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5473 More functions unavailable on some systems.
5474 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5475 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5477 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5478 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5479 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5480 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5481 stub that signals an error as the #else.
5483 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5485 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5487 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5489 * unif.c: include ramap.h.
5491 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5493 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5495 * ports.c: include sys/ioctl.h.
5497 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5499 * configure.in: check for sys/ioctl.h.
5501 * ports.c: include <malloc.h> not "malloc.h".
5503 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5505 * fports.c: remove ttyname and tmpnam declarations.
5507 * posix.c: fewer ttyname declarations.
5509 * fports.c: include <string.h> not "string.h".
5511 * init.c, ioext.c: include string.h and unistd.h.
5513 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5515 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5516 genio.c, simpos.c, vports.c: include string.h.
5518 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5520 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5522 (scm_addr_buffer_size): change type from scm_sizet to int.
5523 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5524 from scm_sizet to int.
5526 * error.c: include unistd.h.
5528 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5531 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5533 * __scm.hd, def.sed: deleted.
5535 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5537 Changes for NeXT, suggested by Robert Brown.
5538 * configure.in: Call AC_TYPE_MODE_T.
5539 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5540 NeXT. Put header file list in alphabetical order.
5541 * configure, scmconfig.h.in: Regenerated.
5542 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5544 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5547 * acconfig.h: New file, providing documentation for the CPP
5548 symbols defined in configure.in
5549 * acconfig-1.5.h: Removed; superceded by the above.
5551 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5553 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5555 * fports.c (scm_open_file): don't return #f, throw error.
5557 * ioext.c (fileno): renamed from %fileno.
5558 (soft-fileno): deleted.
5560 * ports.c (scm_port_revealed): don't need to check for -1 from
5562 (scm_set_port_revealed_x): return unspecified, not #f.
5564 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5566 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5568 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5570 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5572 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5574 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5575 This is necessary on Ultrix, and doesn't hurt portability.
5577 * Makefile.in (dist-dir): New target, implementing a new dist system.
5578 (installed_h_files): Put in alphabetical order.
5579 Remove duplicate entries for markers.h and unif.h.
5580 (c_files): Remove duplicate entries for markers.c.
5581 (ancillary): Renamed from anillery; all uses changed. Remove
5582 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5583 Remove all the ../doc/* files; doc/Makefile.in handles that.
5585 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5587 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5588 every if must have an else, or else the whole command has a
5589 non-zero exit code whenever the if's condition is false.
5591 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
5593 * posix.c: include string.h.
5595 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
5597 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
5600 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
5601 Remove leading % from scheme names.
5602 Do not return error values, call SCM_SYSERROR or similar.
5604 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
5606 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
5608 * struct.c (scm_init_struct): new file.
5610 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
5612 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
5613 (scm_list_head): added list-head for rapidly chopping argument
5614 lists off of longer lists (and similar).
5616 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
5618 * objprop.c (scm_object_property): assq the cdr of the whash
5619 handle for obj, not the handle itself.
5621 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
5623 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
5624 weak hash tables last of all marking to avoid an obscure gc bug.
5625 WARNING: circular lists stored in a weak hash table will hose us.
5627 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
5629 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
5630 new functions similar to scm_substring_move_left_x and
5631 scm_substring_move_right_x.
5633 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
5635 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
5638 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
5640 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
5642 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
5644 * strports.c (scm_strprint_obj): convenience function. C for
5645 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
5647 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
5648 removed to a separate library
5650 * init.c (scm_boot_guile): copied from guile-tcl.c.
5651 Initialization specific to tcl interpreters removed.
5653 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
5655 * ports.c (scm_ports_prehistory): size malloced here doesn't
5656 matter so long as it is non-0 (got rid of "* 4").
5658 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5660 * gscm.h: gscm_mkarray eliminated (presumably was not being used
5661 since its definition was bogus).
5663 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
5665 * mallocs.[ch]: back again (for rx at least).
5667 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5669 * ports.c: removed functions relating to the mapping between ports
5670 and descriptors. (That stuff is unix-specific and should be collected
5671 in a separate library).
5673 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
5674 (Tom Mckay@avanticorp.com)
5676 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
5678 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5679 handled correctly (SCM_FREEP was applied to them) -- test for
5680 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
5681 being overwritten with #f. (brown@grettir.bibliotech.com)
5683 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
5685 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

5688 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
5690 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
5691 keys and weak values confused).
5693 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
5695 * list.c (scm_last_pair): map '()=>'()
5697 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>

5700 Generalized assoc and hash-table functions.
5701 Factored pairs.c into multiple files.
5703 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
5705 * gscm.c (gscm_run_scm): got rid of objprop.
5707 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
5709 * genio.c (scm_getc):
5710 NOTE: fgetc may not be interruptable.
5712 * procprop.c (scm_stand_in_scm_proc):
5713 NOTE: don't use a alist here.
5714 (scm_set_procedure_properties_x): fix type checking throughout this file.
5716 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
5718 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
5719 after freeing part of the port table.
5721 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
5723 * strports.c (scm_mkstrport):
5724 * vports.c (scm_make_soft_port): allocate a port table entry
5725 (possibly triggering gc) before setting the tag of the corresponding
5728 * pairs.c (scm_delq_x): never throw an error.
5730 * vectors.c (scm_make_vector): made the default vector fill argument
5731 into '() (much more useful than the previous value, "#unspecified")
5733 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
5735 * ports.c (scm_add_to_port_table): Added fields
5736 to port table entries: file_name, line_num, col.
5737 Update these in open_file, gen_getc and gen_ungetc.
5738 Added procedures to access those fields.
5740 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
5742 * procs.c (scm_make_subr_opt): new entry point for making
5745 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
5747 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
5749 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
5751 * numbers.c (scm_exact_p): This function no longer
5752 implements "integer?".
5754 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
5756 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
5757 (scm_gc_stats): return an assoc of useful data. Replaces "room"
5758 and the stats reporting formerlly built into repl.
5760 * repl.[ch]: removed.
5761 GC statistics keeping moved to gc.c.
5762 Other statistics keeping can be done from Scheme.
5763 REPLS are now written in Scheme.
5765 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
5767 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
5768 conservatively marked objects).
5770 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
5772 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
5774 * feature.c (scm_compiled_library_path): moved here from repl.c.
5775 This file is for stuff relating specifically to Scheme libraries
5778 * eval.c (scm_m_define): don't give warning about redefinition, don't
5781 NOTE: this should throw a resumable exception with parameters --
5782 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
5784 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
5786 * error.c: scm_warn eliminated.
5788 * read.c (scm_lreadr): extra right paren gets an error, not a warning.
5790 * repl.c, marksweep.c, gc.c (various):
5791 lose exit_report, growth_mon.

5806 because it changes size.
5808 (stputc stwrite): check/change the strings length with interrupts
5811 * objprop.c (scm_set_object_property_x &c): use the generic
5812 hashing functions and be threadsafe.

5842 * symbols.c: made the basic symbol table operations atomic.
5844 * root.c &c.: collected stack-specific global state.

5848 initialization to fix a race condition.
5850 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

5873 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
5874 set the multi_byte flag correctly in symbols. This is wrong.
5875 intern_obbary_soft and msymbolize should take an extra parameter.
5876 Also, weird multibyte symbols don't print correctly.
5877 The weird symbol syntax is also a bit bogus (emacs doesn't quite
5880 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
5882 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
