1 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3 * backtrace.c (display_frame_expr): Don't print a newline.
4 (display_frame): Print the newline here instead.
6 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
8 * procs.c (scm_setter): Signal WTA if handed an entity or operator
11 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
12 primitives. (Thanks to Greg Badros);
13 (scm_hook_to_list): New primitive; Hooks are now smobs.
15 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
17 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
18 of #f for the 10th vector element to avoid an exception
19 seen by Bernard Urban.
20 (scm_mktime): unneeded ASSERT removed.
22 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
24 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
27 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
29 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
31 * numbers.c: Converted comparison operations to dispatch on
32 generic if args don't match.
34 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
36 1999-09-06 James Blandy <jimb@mule.m17n.org>
38 * guile-snarf.c: Deleted. Snarfing should respect CPP
39 conditionals, so it needs to actually run CPP. Bleah.
41 1999-09-05 James Blandy <jimb@mule.m17n.org>
43 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
44 * guile-snarf.in: Be sure to exit with an error if CPP does.
45 * Makefile.am (.c.x): Delete the .x file and exit with an error
46 status if guile-snarf exits with an error status.
47 * Makefile.in: Regenerated.
49 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
50 scm_makekey, which doesn't exist any more. Guess nobody's using
53 * guile-snarf.c: New implementation of guile-snarf, meant to be
54 more robust than the shell script. I think it's complete, but I
55 haven't tested it at all, and I haven't changed the build process
56 to actually use it. We should compare its output against that of
57 the existing shell script, for all source files.
59 * guile-snarf.c (parse_args): Abort if we haven't handled some
62 1999-09-03 James Blandy <jimb@mule.m17n.org>
64 * load.c (scm_search_path): If the filename has any extension at
65 all, ignore the entire list of extensions. Also, don't check whether
66 the file is accessible. If the file exists, accessible or not, we
67 should return it. Inaccessible files should cause an error later.
68 (Thanks to Keisuke Nishida for the suggestions.)
70 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
72 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
73 atexit not available. (sunos4.1.4 needs it.)
75 1999-09-01 James Blandy <jimb@mule.m17n.org>
77 I take it all back --- bcopy does handle overlapping source and
78 destination areas correctly. At least on every system I could
79 find. But it is better to use AC_REPLACE_FUNCS than to introduce
81 * memmove.c: New file, implementing memmove in terms of bcopy.
82 * scmconfig.h.in: Regenerated.
84 Allocators should use the `void *' type for generic pointers.
85 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
86 argument and return types.
87 * gc.h: Corresponding changes to prototypes.
90 1999-08-31 James Blandy <jimb@mule.m17n.org>
92 * numbers.c (scm_init_numbers): Claim to support the `complex'
93 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
95 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
96 find (ice-9 boot-9) when Guile was compiled in a separate
97 directory from the source. (Thanks to Rodney Brown.)
98 * Makefile.in: Regenerated.
100 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
101 table lengths by the size of a single element when growing the
102 table. (Thanks to Bill Schottstaedt.)
104 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
106 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
107 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
108 since that cuts down the time for type dispatch by 50%.
110 1999-08-30 James Blandy <jimb@mule.m17n.org>
112 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
113 not a correct substitute for memmove, because it doesn't handle
114 overlapping source and destination areas on many platforms.
115 Overlaps are the primary reason to use memmove in the first place.
116 * ports.c (scm_ungetc): Same.
117 * strop.c (scm_substring_move_x): Same.
119 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
121 * gc.c (scm_init_storage): Skip registration of cleanup on systems
122 which lack atexit. (Is it important that cleanup is made
123 properly? Maybe we should replace all `exit' with `scm_exit' and
126 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
127 scm_struct_free_standard, scm_struct_free_entity): Declared to
128 return scm_sizet instead of size_t.
130 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
131 there on sunos4.1.4.)
133 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
135 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
136 Account for the case when second argument is unbound.
138 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
139 (Thanks to Karoly Lorentey.)
141 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
142 isn't present. (Thanks to Suzuki Toshiya.)
144 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
147 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
150 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
151 Bernard Urban and Ian Grant.)
153 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
154 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
155 change in the representation of entities and operators.)
157 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
159 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
160 don't allocate zero bytes (thanks to Bill Schottstaedt).
162 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
164 * procs.c (scm_setter): Converted to use generic dispatch.
166 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
169 * load.c (scm_search_path): Don't try extensions which already are
170 present at the end of the filename.
171 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
173 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
175 Cleanup and simplification of generic method dispatch.
176 Also, the quadruple representation of entity and operator
177 procedures has been replaced with single.
179 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
181 * print.c (scm_isymnames): Removed #@hash-dispatch.
183 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
184 from eval.c; Support 0 arity methods.
185 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
186 (scm_apply_generic_env): Removed.
187 Replaced slots proc0-3 with procedure.
189 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
190 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
191 SCM_OPERATOR_PROCEDURE.
192 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
193 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
195 * struct.c, struct.h: Replace 4 procedure slots with one.
196 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
198 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
201 * eval.c (scm_sym_args): Removed.
202 (SCM_CEVAL): Simplified entity application.
203 Moved dispatch code to objects.c.
205 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
207 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
209 * sort.c (closureless): Use scm_eval_body.
211 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
212 with a symbol as last form was first called normally and then via
213 `map' or some other mechanism using primitive apply, an ILOC was
216 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
218 This change extends the representation of primitive procedures
219 with more data fields, e.g. a place for documentation and true
220 procedure properties.
222 * procs.c, procs.h (scm_subr_entry): New type: Stores data
223 associated with subrs.
224 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
225 SCM_SUBR_DOC): New macros.
226 (scm_subr_table): New variable.
227 (scm_mark_subr_table): New function.
229 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
231 * gc.c (scm_gc_mark): Don't mark subr names here.
232 (scm_igc): Call scm_mark_subr_table.
235 This change implements a scheme for letting a generic work as a
236 shadow for a primitive procedure. If the primitive procedure
237 can't dispatch on its arguments, control is left over to the
238 generic. Normal wrong type arg errors will be generated until the
239 user has hung the first method on the primitive.
241 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
243 * procs.c, procs.h (scm_subr_p): New function (used internally).
245 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
247 * objects.c, objects.h (scm_primitive_generic): New class.
249 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
251 * print.c (scm_iprin1): Print primitive-generics.
253 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
254 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
256 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
257 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
258 primitives). NOTE: This means that it is now *required* to use
259 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
260 obscured representation that will be removed in the future anyway,
261 so backward compatibility is no problem here).
263 * numbers.c: Converted most numeric primitives (all but bit
264 comparison operations and bit operations) to dispatch on generic
268 Better support for applying generic functions.
270 * eval.c, eval.h (scm_eval_body): New function.
272 * objects.c (scm_call_generic_0, scm_call_generic_1,
273 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
277 Optimization of the generic function dispatch mechanism.
279 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
280 called scm_memoize_method instead of doing a second lookup.
282 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
287 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
288 scm_sysintern so that the binding connected with the subr name
289 isn't cleared when we give set = 0.
292 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
294 More transparent handling of ports with print states.
296 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
297 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
298 instead of a pair of a port and a print state. We'll need to cons
299 once extra in scm_printer_apply but the type system will be
300 cleaner, it will mix better with GOOPS, and, it will be even more
301 transparent to the user.
303 * print.c (scm_get_print_state): New procedure: Given an output
304 port, return the print state associated to it in the current print
305 chain, if one exists;
306 (scm_port_with_print_state): New procedure: Associate a
307 print-state with a port.
308 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
309 (scm_printer_apply): Wrap port and pstate as a smob;
310 (print_state_printer): Removed.
312 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
314 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
317 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
318 testing (otherwise the port-print-state trick won't be transparent
319 to the user; one example where this caused problems was in the
320 (ice-9 format) module).
322 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
324 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
325 SCM_UNSPECIFIED instead of the set value.
327 1999-08-20 James Blandy <jimb@mule.m17n.org>
329 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
331 * ports.h (enum scm_port_rw_active): New enum, containing
332 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
333 zero). The debugger knows about enums, but doesn't know about
335 (typedef scm_port): Declare rw_active member to be an enum
337 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
339 * ports.c (scm_add_to_port_table): Same.
340 * strports.c (st_flush, st_end_input): Same.
342 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
343 scm_must_realloc, and scm_done_malloc as appropriate.
345 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
347 * sort.c (quicksort): Added condition to protect the algorithm
348 from crashing the interpreter if the less predicate is buggy.
350 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
352 * fports.c (fport_write): fix line-buffering mode again.
353 (scm_open_file): recognise 'l' for line-buffering.
354 (scm_setvbuf): recognise _IOLBF for line-buffering.
356 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
358 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
361 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
364 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
366 * fports.c (fport_write): use memcpy instead of strncpy, in case
367 the data contains NUL.
369 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
371 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
373 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
374 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
375 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
376 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
377 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
378 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
379 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
380 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
381 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
382 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
383 scm_sym_ as prefix for symbols.
385 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
387 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
388 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
389 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
390 scm_sym_atcall_cc): Made global.
392 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
394 * eval.c (scm_sym_args): Made global.
396 * objects.c (scm_set_object_procedure_x): Disallow setting of
397 procedures for pure generic functions.
399 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
401 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
402 Scheme name from lseek to seek, but lseek was added recently so
403 it shouldn't be a big problem.
404 * ports.c, gdbint.c, ioext.c: changed callers.
406 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
408 * fports.c (fport_input_waiting): if select is used, return 1
409 instead of whatever FD_ISSET expands to. maybe it will be useful
410 to interpret the value from the input_waiting ptob procedure as a
411 lower bound on the number of bytes available.
413 * Mikael asked for a few names to be changed...
415 * ports.c (scm_make_port_type): take the write procedure as the
416 second argument instead of the flush procedure.
417 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
418 fflush -> flush, read_flush -> end_input, fclose -> close,
419 fill_buffer -> fill_input, ftruncate -> truncate,
420 input_waiting_p -> input_waiting.
422 * ports.c (end_input_void_port): was read_flush_void_port.
423 (scm_set_port_end_input): was scm_set_port_flush_input.
424 (scm_set_port_flush): was scm_set_port_write.
425 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
426 (scm_end_input): was scm_read_flush.
427 (scm_fill_input): was scm_fill_buffer.
428 (scm_flush): was scm_fflush.
429 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
430 (fport_end_input): was local_read_flush.
431 (fport_flush): was local_fflush.
432 (fport_close): was local_fclose.
433 (fport_truncate): was local_ftruncate.
434 (fport_seek): was local_seek.
435 (fport_free): was local_free.
436 (fport_fill_input): was fport_fill_buffer.
437 * strports.c (st_end_input): was st_read_flush.
438 (st_truncate): was st_ftruncate.
439 * vports.c: (sf_flush): was sfflush.
440 (sf_close): was sfclose.
441 (sf_fill_input): was sf_fill_buffer.
443 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
446 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
448 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
449 forms now contain the expressions to be dispatched upon instead of
450 depending on a surrounding lambda or let; Generic function
451 dispatch has been optimized; `apply' on a generic function now
452 works a little bit strangely. It uses a trick so that the type
453 dispatch code in SCM_CEVAL can be reused.
455 * objects.h, objects.c (scm_apply_generic_env): Added (used by
457 (scm_operator_p): Added.
458 (scm_sym_atdispatch): Added.
459 (scm_set_object_procedure_x): Modified to handle the new style
461 (scm_object_procedures): New debugging procedure.
463 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
465 * eval.c, eval.h (scm_sym_args): Added.
467 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
469 * feature.c, feature.h (scm_c_run_hook): Added.
471 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
472 cdrxnoap and loopnoap instead of begin and loop.
474 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
476 * ports.c (scm_putc, scm_puts),
477 * unif.c (scm_uniform_array_write): use scm_lfwrite.
478 * ports.c (scm_putc): change type of first argument from int to char.
480 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
482 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
483 SCM_IM_HASH_DISPATCH.
485 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
486 (scm_si_redfined, scm_si_hashsets): Moved.
488 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
489 flag which combines type and status info so that the class
490 redefinition protocol has zero cost during normal execution.
492 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
494 * ports.h (scm_ptob_descriptor): include a write procedure again.
495 it's more efficient for unbuffered fports (e.g., sockets.)
497 * ports.c (scm_puts): use ptob->write.
498 * vports.c (scm_make_sfptob): set write proc in ptob.
499 * strports.c (scm_make_stptob): set write proc in ptob.
500 * ports.c (write_void_port): new procedure.
501 * vports.c (sf_write): new procedure.
502 * ports.c (scm_lfwrite): use ptob->write.
503 * strports.c (st_write): new procedure.
504 * fports.c (fport_write): new procedure.
505 (scm_make_fptob): set write in ptob to fport_write.
506 * ports.h: prototype for scm_set_port_write.
507 * ports.c (scm_make_port_type): initialise ptob write procedure.
508 (scm_set_port_write): new proc.
510 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
512 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
513 until we've verified that it is actually a port. (Thanks to
516 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
518 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
519 code, particularly an unnecessary test (len != size, where len ==
520 size). (Was this leftovers from debugging code, or have I missed
523 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
524 size. (Thanks to James Dean Palmer.)
526 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
527 (Thanks to Lorentey Karoly.)
529 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
531 * eval.c (scm_m_expand_body): Use scm_cons_source.
533 * struct.c (scm_print_struct): Use vtable name.
535 * print.c (scm_init_print): Set name of print state type.
537 * stacks.c (scm_init_stacks): Set name of stack type.
539 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
541 * eval.c (SCM_CEVAL): Removed old implementation of internal
544 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
546 * debug.c, debug.h (scm_reverse_lookup): Added.
547 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
548 internal procedure definitions; Don't use scm_i_inner_name.
550 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
553 * eval.h: Added prototypes for multi language support functions.
555 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
556 improper lists in the low-level representation, since that will
557 cause a begin to be prepended at macro expansion.
559 * eval.c (scm_cons_source): Version of cons which copies source
560 properties from an existing cell.
561 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
563 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
564 procedure source before calling scm_unmemocopy instead of faking
567 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
569 Ported `internal defines' fix from SCM. Original ChangeLog entry:
571 1998-07-09 Radey Shouman <radey@colorage.com>
573 * eval.c (ceval_1): Modifications to allow rewriting of interal
574 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
575 body of which it is the CAR is macro expanded by m_expand_body,
576 which rewrites internal DEFINE.
578 (m_expand_body): Added.
580 (m_macroexp1): Added argument to control error checking:
581 m_expand_body may speculatively expand forms in the wrong
582 environments. Made argument number checks conditional on
585 (m_body): Added, error checks bodies and inserts the ISYM tokens.
587 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
590 (m_cond): (m_case): (m_quote): Modified to avoid destructively
591 changing their argument forms. Since m_expand_body
592 speculatively macro expands forms the process must be
595 (m_ident_eqp): Fixed to use proper environment.
597 (renamed_ident): Added DEFER_INTS_EGC.
599 Added prototypes for static functions.
605 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
606 is false, do not produce an error for unbound variables, return a
607 pointer to cell_undef instead.
609 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
613 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
614 destructively changing their argument forms. Since m_expand_body
615 speculatively macro expands forms the process must be reversible.
617 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
618 SCM_IM_LET introduced by named lets.
620 (scm_m_letstar): Use scm_m_body instead of bodycheck.
622 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
623 scm_letrec. scm_letrec1 does not check for a null binding and
624 takes an additional argument to specify the ISYM of the body. Use
625 scm_m_body instead of bodycheck.
627 (scm_m_let): Use scm_m_body instead of bodycheck.
629 (scm_m_expand_body, scm_macroexp): New.
631 (unmemocopy): Account for ISYMs introduced by scm_m_body.
633 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
634 check=1. Throw error for internal defined that have not been
635 rewritten by scm_m_expand_body.
637 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
638 Removed prototype for SCM_APPLY.
640 * tags.h: Added extern declaration of scm_isymnames.
642 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
644 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
646 * lang.c: New file: Beginning of multi-language support.
648 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
650 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
651 (scm_dynamic_wind): Added argument checking for the after guard so
652 that we don't add garbage on the dynwind chain.
653 (scm_swap_bindings): Added.
655 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
656 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
657 (scm_isymnames): New isyms for multi-language support.
659 * eval.c (scm_nil, scm_t): New symbols.
660 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
661 forms for multi-language support.
663 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
665 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
667 Renamed functions in the random function library interface
668 from scm_i_XXX --> scm_c_XXX.
670 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
672 * ports.c (scm_putc): fix line-buffering.
674 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
676 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
677 scm_set_ptob_XXX --> scm_set_port_XXX.
679 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
681 * ports.c, ports.h (scm_make_port_type): New interface for
682 creation of port types (replaces scm_newptob). Just as for the
683 smobs, we need to separate the internal representation of smob
684 types from the interface, so that we easily can add new fields and
685 rearrange things without caring about backward compatibility.
686 This change was forced by the need in GOOPS to create classes
687 representing port types.
688 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
689 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
690 scm_set_ptob_seek, scm_set_ptob_truncate,
691 scm_set_ptob_input_waiting_p): New setters.
692 (scm_newptob): Rewritten to use scm_make_port_type. For backward
694 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
695 (scm_prinport): Removed.
696 (scm_port_print): Added.
697 (scm_print_port_mode): Added.
698 (void_port_ptob, print_void_port, close_void_port, noop0):
699 Removed. Removed #include "genio.h" Added #include "objects.h",
702 * fports.c (prinfport): Moved code from ports.c.
704 (scm_fptob): Removed. Instead use new interface.
705 (scm_make_fptob): Added. (Need to create basic ports in a
706 specific order in ports.c.)
708 * strports.c (scm_stptob, prinstpt, noop0): Removed
709 (scm_make_stptob): Added.
711 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
712 (scm_make_sfport): Added.
714 * filesys.c (scm_dir_print): Don't use the port printing code.
715 Instead provide specific directory printer.
717 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
719 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
722 * smob.c (scm_smob_print): Handle non-existing type name nicely.
723 Removed #include "genio.h"
725 * objects.c (scm_make_port_classes): New function ptr.
727 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
729 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
731 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
732 allow the 1st argument to be a fdes or filename as well as a
733 port (as in the filesys.c version).
735 * filesys.c (scm_truncate_file): removed.
737 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
739 * readline.c, readline.h: Removed.
741 * objects.c, objects.h (scm_port_class): Added.
742 (scm_class_of): Look up port class in scm_port_class.
743 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
744 SCM_INOUT_PCLASS_INDEX): Added.
747 * Makefile.am: Removed genio.c, genio.x.
751 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
753 * init.c: Make sure that scm_post_boot_init_modules is called only
754 once. (Important when using a dumped image.; Thanks to Bernard
757 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
759 * guardians.c (scm_guardian_zombify): Separate scanning for
760 zombies from marking the pairs of the free list.
762 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
763 use the macros. (Thanks to Michael Livshin.)
765 * eval.c (scm_m_lambda): Let bodycheck check the body of the
766 lambda. Let your sins be purified by the blood of the lambda.
767 (Thanks to Eric Hanchrow.)
769 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
770 (Thanks to Valdis Kletnieks.)
772 Fixes for EMX from Mikael Ståldal.
774 * filesys.c: #include <io.h>, if we have it.
775 * scmconfig.h.in: Regenerated.
777 * stime.c (ftime): Delete declaration for this function --- let
778 the system supply it.
780 Cleanups from John Bley.
782 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
784 * gsubr.c: Don't include "gsubr.h" twice.
786 Cleanups for compilation on Irix 6, from David Kaelbling.
788 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
789 regex_t pointer. This is what the callers have, mostly.
790 (scm_regexp_exec): Don't forget to pass the `rx' argument to
791 scm_regexp_error_msg.
793 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
794 int. That way, if we get a warning on this line, it's more likely
795 that we're really missing bits we care about.
797 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
800 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
801 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
802 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
803 cast at all is more appropriate in every case. At the moment, we
804 assume everywhere that SCM is an integral type anyway.
806 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
808 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
809 read_pos after scm_fill_buffer.
811 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
814 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
815 fports.c (fport_fill_buffer): implement the interface change.
817 * ports.c (scm_fill_buffer): interface change: no longer increments
818 read_pos past the character that's returned. it seems clearer to
819 leave it to the caller to decide what to do (thanks Jim).
821 * vports.c (sf_fill_buffer): put the read char into the buffer
822 as well as returning it.
824 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

829 * strports.c (scm_strprint_obj): simplify. start with initial
831 (st_seek): don't allow string to be extended if seeking past
832 the end of a read-only port.
834 1999-07-12 Gary Houston <ghouston@easynet.co.uk>
836 * strports.c (st_seek): change the resize checks.
838 * ports.c (scm_ftruncate): throw error if offset works out negative.
840 * strports.c (st_flush): increase string size in blocks of
841 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
842 it's greater and reset read_buf_size.
843 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
844 to be maintained for output ports too (it holds the written
845 part of the string, while write_buf may have unwritten buffer
847 (st_truncate): rewritten.
848 (top of file): added a few notes.
850 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
852 Patch from Greg Badros:
853 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
854 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
855 (function pointer) argument to scm_make_gsubr and scm_make_subr
856 calls. This avoids warnings in C++ programs using guile-snarf.
858 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
860 * strports.c (st_grow_port): set pt->read_pos. set
861 pt->read_buf_size one less than pt->write_buf_size if there's
862 an unwritten char at the end of the string. similarly for
864 (st_resize_port): renamed from st_grow_port.
865 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
866 seek from read_end instead of write_end for SEEK_END.
867 (st_ftruncate): calculate current length using readbuf, not write

875 (scm_call_with_output_string, scm_strprint_obj): use
876 scm_strport_to_string.

879 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
881 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)

889 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
890 SCM_RETURN_NEWSMOB macro. Added protos for new functions in

894 use SCM_NEWSMOB or SCM_RETURN_NEWSMOB in constructors instead of
895 SCM_NEWCELL and setting the CAR/CDR by hand.

979 trinary conditional in order for the flag computation to be
982 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
984 * struct.c, struct.h:
986 In order to support different kinds of deallocation, a destructor
987 slot has been added to struct vtables. This allows for structs
988 containing pointers to other memory blocks.
990 (scm_struct_i_free): New hidden struct slot. Holds destructor for
991 instances to this vtable.
992 (scm_struct_free_0): New destructor: Doesn't deallocate data.

1068 proper lists, and of the appropriate lengths.
1069 (check_map_args): New function. (Thanks to Greg Harvey for the

1093 * gc.h (scm_mallocated): Fix declaration.
1094 (Thanks to Greg Harvey.)
1096 * ports.h: #include <sys/types.h>, to get a definition for `off_t'.

1100 * stime.c (bdtime2c): Initialize lt->gmtoff and lt->tm_zone from
1101 sbd_time. (Thanks to Eric Hanchrow.)
1103 Fix from Ken Raeburn <raeburn@raeburn.org>:
1104 * weaks.c (scm_make_weak_vector): Add another extra slot before
1105 vector contents, to be used only during garbage collection.
1106 * weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
1107 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
1109 (scm_weak_size, scm_n_weak): Deleted.
1110 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
1111 vectors without allocating new storage during GC, using
1112 scm_weak_vectors as the head of the chain.
1113 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1114 instead of stepping through an array.
1115 (scm_gc_sweep): Update offset used to find start of weak vector to
1117 (scm_init_storage): Set scm_weak_vectors to EOL.
1119 Fix from Ken Raeburn <raeburn@raeburn.org>:
1120 * gc.c (already_in_gc): New variable.
1121 (scm_igc): Set and clear already_in_gc; abort if it's set at
1124 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
1126 Fix from Gary Houston:
1127 * fports.c (local_seek): Signal an error if the seek fails.
1128 * ports.c (scm_lseek): Don't check return value of port's seek
1129 function; it's its job to signal an error if there's a problem.
1131 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
1133 * strports.c (scm_call_with_output_string): Don't include the
1134 extra character at the end of the string in the result.
1136 * ioext.c (scm_read_line): Switch to reading properly.
1138 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
1139 scmsigs.c, strports.c, vports.c: Install the sources which
1140 actually correspond to the changes described below. I got the
1141 ChangeLog entries and the patch from two different places...
1143 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1145 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1146 it shows up as terrible performance, as we GC constantly.
1148 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1149 newline. A bit faster, and definitely hairier.
1150 (scm_read_line): Count newlines here instead.
1152 * strings.c (scm_take_str): New function.
1153 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1154 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
1155 scm_take_str, to avoid copying the string.
1157 Add some simple-minded support for line buffered ports.
1158 * ports.h (SCM_BUFLINE): New flag for ports.
1159 * init.c (scm_init_standard_ports): Request line-buffering on
1160 the standard output port.
1161 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1163 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1164 and there's a newline to be written, flush the port.
1166 Gary Houston's open-buffer port patches:
1168 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1170 * ports.c: (scm_lseek): clear buffers even if just reading current
1173 * fports.c (local_fclose): call local_fflush unconditionally.

1176 1999-04-25 Gary Houston <ghouston@easynet.co.uk>
1178 * ports.h (scm_port): make read_pos a pointer to const.
1179 strports.c: take care of rw_active and rw_randow.
1180 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
1181 strports.c (scm_mkstrport): check that pos is reasonable.
1182 ioext.c (scm_ftell, scm_fseek): use lseek.
1183 (SCM_CLEAR_BUFFERS): macro deleted.

1186 ports.c (scm_newptob): set ftruncate.
1188 ports.c (scm_ftruncate): new procedure.
1189 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
1190 strports.c (st_seek, st_grow_port): new procs.
1191 fports.h (scm_port): change size types from int to off_t.
1192 ports.c (scm_init_ports): initialise the seek symbols here
1193 instead of in ioext.c.
1194 strports.c (scm_call_with_output_string): start with an empty
1195 string, so seek and ftruncate can be used.
1197 gdbint.c: adjust string port usage.
1199 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1201 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1202 equivalent to fflush for the read buffer.
1203 * ports.c (scm_newptob): set read_flush.
1204 ports.c (void_port_ptob): set read_flush.
1205 fports.c (local_read_flush): new proc. add to ptob.
1206 strport.c (st_read_flush): likewise.
1207 vport.c (sf_read_flush): likewise.
1208 fports.h (struct scm_fport): remove random member. there's nothing
1209 left but fdes. leaving it as a struct to allow for future changes.
1210 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1211 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1212 ptob proc if the read buffer is filled.
1214 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1216 * ports.h (scm_port): add a rw_random member and replace
1217 reading and writing members with rw_active member.
1218 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1220 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1222 * ports.h (struct scm_port_table): add writing and reading members
1223 to replace write_needs_seek: it isn't good enough for non-fports.
1224 ports.c, ioext.c, fports.c: corresponding changes.
1225 (struct scm_port_table): give it a typedef and rename to scm_port.
1226 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1227 corresponding changes.
1229 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
1231 * ports.c (scm_newptob): bugfix: set seek member.
1232 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
1233 and generalised to all port types.
1235 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
1237 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1238 signals (it was only being done for handlers installed from Scheme).
1239 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1240 waiting for input caused an EINTR error from read.
1242 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1244 * ports.h (struct scm_port_table): make all the char members
1245 unsigned, so they convert to int without becoming negative if large.
1247 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1249 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1250 with threads enabled. rename this procedure to
1251 fport_wait_for_input and take a port instead of a fdes.
1252 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1254 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1255 get readline support working again: use fdopen to get FILE objects.
1257 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1259 * gc.c (scm_init_storage): install an atexit proc to flush the
1261 (cleanup): the new proc. it sets a global variable which can be
1262 checked by the ptob flush procs to avoid trying to throw
1263 exceptions during exit. not very pleasant but it seems more reliable.
1264 * fports.c (local_fflush): check terminating variable and if set
1265 don't throw exception.
1266 * CHECKME: that the atexit proc is installed if unexec used.
1268 * throw.c (scm_handle_by_message): don't flush all ports here.
1269 it still causes bus errors.
1271 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1272 and move to ioext.c.
1274 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1276 * ports.c (scm_char_ready_p): check the port buffer and call the
1277 ptob entry if needed.
1279 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1280 ptob initialisers. use it in char-ready
1282 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1284 * vports.c (sfflush): modified to write a char (since softports
1285 currently use shortbuf.)
1287 * fports.c (scm_standard_stream_to_port): moved to init.c and
1290 * init.c (scm_init_standard_ports): make stdout and stderr
1291 unbuffered if connected to a terminal. with stdio they
1292 were line-buffered by default.
1294 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1297 * ports.h (scm_ptobfuns): change fflush return to void.
1298 change flush proc definitions.
1300 * strports.c (scm_call_with_output_string): get size from
1301 buffer instead of port stream.
1302 (st_flush): new proc.
1304 * ports.h (struct scm_port_table): added write_end member,
1305 as an optimisation. set it where write_buf_size is set.
1307 * ports.h (struct scm_port_table): change stream from void *
1308 back to SCM. SCM presumably must be large enough to hold a
1309 pointer (and probably vice versa but who knows.)
1310 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1312 (scm_puts): rewritten
1313 * fports.c (local_ffwrite, local_fputs): removed.
1314 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)
1315 * vports.c (sfputc, sfputs, sfwrite) likewise.
1316 * ports.c (write_void_port, puts_void_port): removed.
1317 (putc_void_port, getc_void_port, fgets_void_port): likewise.
1319 * ports.c (scm_lfwrite): rewritten using fport.c version.
1321 * fports.c (local_fputc): deleted.
1323 * ports.c (scm_add_to_port_table): initialise write_needs_seek.
1325 * ports.h (scm_ptobfuns): add seek function pointer.
1326 * fports.c: set it to local_seek, new procedure.
1329 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1330 use ptob for seek. take ptob instead of fport arg.
1332 * ports.h (struct scm_port_table): new member write_needs_seek,
1333 replaces reading member in fport struct.
1335 * vports.c (sfgetc): store the getted char into the buffer.
1336 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1337 the Scheme interface is still a procedure that gets a char.
1338 (scm_make_soft_port): set up the port buffer (shortbuf).
1340 * fports.c (local_fgetc, local_fgets): deleted.
1341 * strports.c (stgetc): likewise.
1342 * ports.c: scm_generic_fgets: likewise.
1344 * ports.h (scm_ptobfuns): add fill_buffer.
1345 * ports.c (scm_newptob): assign it.
1346 * strports.c (scm_mkstrport): set up the buffer.
1347 put just the string into the stream, not cons (pos stream).
1348 (stfill_buffer): new proc.
1350 * ports.h: fport buffer moved into port table: to be
1351 used for all port types.

1422 ports.c fports.c ioext.c posix.c socket.c net_db.c filesys.c:
1423 removed all uses of SCM_DEFER/ALLOW ints for now. they were mainly
1424 just protecting errno. some may need to be put back.

1581 * strop.h: fixed prototypes.
1583 * strop.c (scm_substring_move_left_x, scm_substring_move_right_x):

1624 linking crashes on NetBSD. (Thanks to Ken Raeburn.)
1626 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1628 * numbers.c (isfinite): Define this macro if not defined: Return a
1629 non-zero value if X is finite. (From ISO C 9x standard.)

1682 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1684 Most of this batch of changes is about how to deal with extended
1685 types when an object system is loaded into Guile. A nice object
1686 system is capable of representing Guile's types as class objects.
1688 For example, we want a regular expression to be of class <regex>.
1689 But regular expressions are smobs which aren't under direct
1690 control of the object system, so there has to be some mechanism
1691 which informs the object system that a new class should be created
1692 which can represent the smob type. I call this a "wrapper class".
1694 * objects.c: #include "smob.h";
1695 (scm_class_keyword): Removed. (Class is automatically created by
1697 (scm_smob_class): Array of smob classes indexed by smobnum.
1698 (scm_make_extended_class): "Plugin" function pointer for creation
1699 of wrapper classes for smob and struct types.
1700 (scm_class_of): Handle compiled closures. (Currently regarded as
1702 Use scm_smob_class to handle smob types;
1703 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1704 through scm_smob_class;
1707 * smob.c (scm_newsmob): Also create a wrapper class if
1708 scm_smob_class has been initialized.
1710 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1711 type code and smobnum.
1713 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1714 (scm_struct_table): Weak key table with auxilliary information for
1715 struct types. Currently used for names and wrapper classes.
1716 (scm_struct_ihashq): Hash function for structs.
1717 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1718 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1719 for accessing names of vtables. The record implementation in
1720 boot-9.scm currently uses the setter to record the name of record
1721 types. When the object system is initialized, it can use this
1722 information to create wrapper classes with suitable names.
1723 (scm_init_struct): Allocate scm_struct_table.
1724 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1725 (struct tags are a finite resource and we might want to restrict
1726 the use of tags to vtables only. E.g., Goops only uses tags for
1728 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1730 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1733 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1734 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1735 Used for access of struct table entries.
1737 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1738 (scm_hash_fold): New procedure. Used to process all entries in a
1739 hash table (in no particular order).
1741 Argh! For the umpteenth time I got compilation errors because of
1742 the "intuitive" name `kw'. This has to have an end:
1744 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1745 "kw" --> "keywords" everywhere.
1746 (I doubt that this will cause big compatibility problems since the
1747 application interface is unaffected.)
1749 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1751 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1753 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1754 column inums to native form.
1756 Improvement of backtraces: Introduces a new stack narrowing
1757 specifier, #t, for the inner cut. (See further in the comments in
1758 stacks.c:narrow_stack ().)
1760 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
1761 (Used to flag certain system procedures which shouldn't turn up in
1764 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1765 modules which aren't "user" modules and the code of which
1766 shouldn't turn up in backtraces.)

1776 * debug.c (scm_procedure_name): Use name property in the default
1779 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1781 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1783 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1784 procedure throughout.
1786 * print.c (scm_iprin1): Removed extraneous space when printing
1787 procedure-with-setters.
1789 Entity and operator setter slots were introduced as a complement
1790 to the <procedure-with-setter> type in order to support entities
1791 and operators with setters in a reasonable and efficient way.
1792 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1795 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1808 directly through the instance.
1810 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1812 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1813 scm_struct_i_flags instead of scm_vtable_index_layout!
1815 * list.c (scm_list_star): New procedure.
1817 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1898 SYMB now point to const.
1900 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1902 * print.c (scm_iprin1): Use scm_procedure_name instead of
1903 scm_procedure_property for compiled closures.
1905 * tags.h (scm_tc7_pws): New procedure type. Four representations
1906 for procedure-with-setters were considered before selecting this
1909 1. A closure where the CODE and ENV slots are used to represent
1910 the getter and a new SETTER slot is used for the setter. The
1911 original getter is stored as a `getter' procedure property. For
1912 closure getters, the CODE and ENV slots contains a copy of the
1913 getter's CODE and ENV slots. For subr getters, the CODE contains
1916 2. A compiled closure with a call to the getter in the cclo
1917 procedure. The getter and setter are stored in slots 1 and 2.
1919 3. An entity (i.e. a struct with an associated procedure) with a
1920 call to the getter in the entity procedure and the setter stored
1921 in slot 0. The original getter is stored in slot 1.
1923 4. A new primitive procedure type supported in the evaluator. The
1924 getter and setter are stored in a GETTER and SETTER slot. A call
1925 to this procedure type results in a retrieval of the getter and a
1926 jump back to the correct eval dispatcher.
1928 Representation 4 was selected because of efficiency and
1931 Rep 1 has the advantage that there is zero penalty for closure
1932 getters, but primitive getters will get considerable overhead
1933 because the procedure-with-getter will be a closure which calls
1936 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1937 <procedure-with-setter>, but together with rep 2 it suffers from a
1938 three level dispatch for non-GOOPS getters:
1940 cclo/struct --> dispatch proc --> getter
1942 This is because the dispatch procedure must take an extra initial
1943 argument (cclo for rep 2, struct for rep 3).
1945 Rep 4 has the single disadvantage that it uses up one tc7 type
1946 code, but the plan for uniform vectors will very likely free tc7
1947 codes, so this is probably no big problem. Also note that the
1948 GETTER and SETTER slots can live directly on the heap, using the
1949 new four-word cells.
1951 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

2075 Author: Michael N. Livshin.
2077 * gc.h (SCM_MARKEDP, SCM_NMARKEDP): New macros.
2079 * gc.c (scm_igc): Call scm_guardian_gc_init and
2080 scm_guardian_zombify.
2082 * init.c (scm_boot_guile_1): Call scm_init_guardian.
2084 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2086 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
2089 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2091 Move the procedure slots of entities to invisible slots (so that
2092 we can have operator class objects which themselves are entities).
2093 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
2094 SCM_STRUCTF_ENTITY): New constants.
2096 * struct.c (scm_make_struct): Allocate "invisible" room for
2097 procedures if SCM_STRUCTF_ENTITY is set in vtable.
2099 * gc.c (scm_gc_mark): Mark entity procedures.
2101 * struct.c, struct.h (scm_alloc_struct): Renamed from alloc_struct
2103 (scm_struct_init): Renamed from init_struct and made global.
2105 * objects.h (SCM_ENTITY, scm_entity): Removed.
2106 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
2107 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
2109 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
2111 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
2112 of syntactic forms, similar to SCM_PROC.
2113 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
2114 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
2115 for the name symbols when needed.
2117 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
2119 * Makefile.in: Regenerated.
2121 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
2123 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
2124 take the address of _into; it might be a register. Just have
2125 scm_debug_newcell return the new cell.
2126 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2127 taking the address of a place to store it as an argument.
2128 * gc.h (scm_debug_newcell): Change declaration.
2129 (Thanks to Greg Harvey.)
2131 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2133 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
2134 Replaces old names serial-array-copy! and serial-array-map!.
2136 * evalext.c (map-in-order): New name. Replaces serial-map.
2138 1998-12-05 Jim Blandy <jimb@totoro.red-bean.com>
2140 * smob.c (freeprint): New function.
2141 (freecell): Use it to print freed objects, for slightly easier
2144 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2146 * backtrace.c (display_frame): Made more robust. Doesn't throw an
2147 error if no source properties can be found for a frame. (Thanks
2148 to Christian Lynbech.)
2150 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2152 * objects.h: Removed slots direct_supers and direct_slots from the
2153 definitions of the rudimentary classes described by objects.h.
2155 * objects.c, objects.h (scm_entity_p): New procedure. Together
2156 with the predicates scm_procedure_p and scm_struct_p, this
2157 predicate makes it possible to differ between structs, entities
2160 * modules.c, modules.h (scm_resolve_module): New function.
2162 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2164 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2165 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2168 * objects.c (scm_entity_p): New procedure.
2170 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
2171 for asubrs, rpsubrs, lsubrs and lsubr_2s.
2173 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2175 * procprop.h (scm_i_procedure_arity): Added declaration.
2177 * procprop.c (scm_i_procedure_arity): Made global; New code to
2178 handle operators and entities.
2179 (scm_procedure_property): No need to call scm_procedure_p since
2180 scm_i_procedure_arity now does all necessary type checking.
2181 Added #include "objects.h".
2183 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2184 s_add_hook_x --> s_remove_hook_x.
2185 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
2186 Added #include "procprop.h"
2188 * feature.c, feature.h (scm_reset_hook_x): New procedure.
2189 (scm_make_hook): Optional argument defines number of arguments to
2191 (scm_make_named_hook): Take number of args as second arg.
2192 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2193 boot-9.scm for a while); First arg is the hook. The rest are
2194 arguments passed on to the hook procedures.
2196 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2198 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2199 scm_logbit_p): Do the computation in ulongs. This is not as nice
2200 as doing it in bignums, but at least it's good enough for
2201 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2203 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2204 subexpressions. (Thanks to Charbel Jacquin.)
2206 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2208 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2209 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2210 (scm_make_named_hook): New function.
2212 * feature.c: Added #include "eval.h".
2214 * modules.c (scm_make_module): Beautify the module.
2216 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2218 * modules.c, modules.h: New files: C interface to modules. (This
2219 is necessary in order to interface the object system to Guile
2220 properly. The guts of these modules will be replaced by the new
2221 module system in the future.)
2223 * init.c: Added #include "modules.h"
2224 (scm_boot_guile_1): Call scm_init_modules.
2225 (invoke_main_func): Call scm_post_boot_init_modules.
2227 * Makefile.am: Added modules.c, modules.x, modules.h.
2229 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2231 * procs.c: #include "objects.h"
2232 (scm_procedure_p): Return #t also on structs which are operators.
2234 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2235 <operator-metaclass> and <entity-class> to <standard-class>,
2236 <operator-class> and <entity> in order to conform with STKlos
2239 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2240 which isn't an operator.
2241 (SCM_APPLY): Ditto, but jump to badproc.
2243 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2245 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2246 Previously, structs implanted in code were interpreted as forms
2247 the operator of which was a gloc. We solve this by checking for
2248 the zero in the emulated vcell in the struct vtable. Since
2249 implanted structs always will look like forms with a gloc
2250 operator, execution will only be slowed down by maximally one
2251 extra test-and-branch per application.
2253 * evalext.c (scm_definedp): Removed check for isyms; Added a
2254 second optional argument: It is now possible to supply an
2255 evaluation environment in which to look for the symbol.
2257 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2259 * readline.c (scm_init_readline): Set
2260 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2262 * coop.c (coop_condition_variable_wait): Removed
2263 (coop_condition_variable_wait_mutex): Folded logic of
2264 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2265 prevent condvar signal lossage. Previously, another thread could
2266 start to run after unlocking the mutex but before putting the
2267 current thread on the wait queue. If that thread then would
2268 signal the first, the signal would be lost. (Thanks to Christian
2271 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2273 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2276 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2278 * objects.c (scm_i_make_class_object): Renamed from
2279 make_class_object; exported; error checking moved to
2280 scm_make_class_object and scm_make_subclass_object.
2281 (scm_make_class_object, scm_make_subclass_object): Use
2282 scm_i_make_class_object.
2283 (scm_make_subclass_object): Let the subclass have same metaclass
2286 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2288 * debug.c (scm_debug_options): Bugfix: Set the value of
2289 scm_stack_checking_enabled_p after setting debug options;
2290 #include "stackchk.h". (Thanks to Richard Polton.)
2292 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2294 * unif.c (scm_array_contents): removed unnecessary test for 0
2297 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2299 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2300 Replaced by macro `collect' in boot-9.scm.
2302 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2304 * eval.c (scm_copy_tree): Copy source properties if existent.
2306 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2307 don't, we may end up passing memoized source to a transformer.)
2309 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2311 * stack.c (get_applybody): Help function which lookups the first
2312 body form of the apply closure.
2313 (read_frames): Prevent the source of the first form of the apply
2314 closure from being recorded. This would only be confusing.
2316 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2317 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2319 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2321 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2323 (read_frames): Use SCM_MACROEXPP.
2325 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2327 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2328 don't contain interesting information since all arguments are
2329 present in the frame which applies the compiled closure anyway.);
2330 Skip the transformer application frames.
2332 * print.c (scm_iprin1): Print gsubrs as primitives.
2334 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2336 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2338 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2339 that we can identify these in a backtrace. (This change doesn't
2340 introduce any significant speed penalty.)
2342 * eval.c: Added note about `serial-map' using scm_map.
2344 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2345 readline options. They should reside in their own options array.
2347 * readline.c, readline.h (scm_readline_options,
2348 scm_readline_opts): Moved readline options here.
2350 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2352 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2353 SCM_ROCHARS instead of SCM_CHARS.
2355 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2356 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2358 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2360 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2361 This is quite important since the latter clears the
2362 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2363 every single character read...
2365 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2367 * print.c (scm_iprin1): Removed suspect looking (and indeed
2368 malevolent) semicolon after test for user supplied closure print
2369 procedure. (Thanks to Telford Tendys.)
2371 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2372 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2373 starting to search the list. Removed call to sloppy_mem_check.
2375 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2376 procedures: Same as scm_delq_x et al, but delete maximally one
2379 * options.c (scm_options, scm_init_options): GC-protect option
2380 values of type SCM. (Thanks to Telford Tendys.)
2382 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2384 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2385 make sure that there always is a "real" scm_lookupcar.
2387 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2389 * read.c, read.h (scm_read_opts): New read options
2390 "history-length" and "history-file".
2391 (scm_read_options): Stifle history to history length.
2393 * readline.c (scm_read_history, scm_write_history): New procedures.
2395 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2397 * eval.h (scm_macro_eval_x): Removed declaration.
2399 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2400 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2401 Renamed and made global.
2403 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2404 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2406 * evalext.c, evalext.h: New files. Contain non-R5RS things
2407 having to do with evaluation.
2409 * evalext.c (scm_serial_map): New procedure: Version of `map'
2410 which guarantees that the procedure is applied to the lists in
2412 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2413 returns a list of the results of the body forms instead of the
2414 result of the last body form.
2415 (scm_definedp, scm_m_undefine): Moved from eval.c
2417 * evalext.h (scm_m_sequence_to_list): Added declaration.
2419 * macros.c, macros.h: New files.
2420 (scm_procedure_to_syntax, scm_procedure_to_macro,
2421 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2422 scm_macro_name, scm_macro_transformer): Moved from eval.c
2423 (scm_make_synt): Moved from eval.c
2425 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2427 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2430 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2432 * debug.c, print.c: Added #include "macros.h".
2434 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2436 This change adds the ability to use `unread-char' multiple times
2437 without interspersed reads and adds the new procedure
2438 `unread-string'. The change is optimized for the common case of
2439 unreading a single character. This is also the reason behind the
2440 choice to store characters in the port itself: in most cases no
2441 extra malloc is required.
2443 The amount of code in some macros in ports.h has been increased to
2444 the extent that they would fit better as C functions, but, since
2445 this code belongs to the port representation, such functions
2446 should be placed in ports.c which would cause calls back and forth
2447 between ports.c and genio.c. That is not good for performance.
2448 Also, keeping them as macros allows the compiler to do some
2449 optimizations which are needed to make the current interface
2450 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2452 One benchmark (Guile startup time) indicates an increase of
2453 loading speed of 1%. Another (reading (using `read') boot-9.scm
2454 10 times) shows no change in performance.
2456 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2457 made to find a beautiful solution.)
2459 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2460 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2461 character. (SCM_CLRDY clears all.)
2462 (SCM_N_READY_CHARS): New macro: Returns number of unread
2463 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2464 (struct scm_port_table): New fields: `entry' contains port table
2465 index, `cp' points to last unread char, `cbuf' is the buffer for
2466 unread chars, `cbufend' points after end of the character buffer.
2468 * ports.h, ports.c (scm_unread_string): New procedure.
2469 (scm_grow_port_cbuf): New function.
2471 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2473 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2474 to read unread characters. Use SCM_TRY_CLRDY instead of
2477 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2479 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2481 * genio.c, genio.h (scm_ungets): New function.
2483 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2486 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2488 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2489 declarations. (Thanks to Russ McManus.)
2491 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2493 * numbers.c (num2long): As a software archeologist, I'm proud of
2494 this finding! :) Preliminary dating suggests an almost 4 year old
2495 remnant from the SCM ancestor. The sample has been removed from
2496 the finding site and is now safely stored in the repository.
2498 * numbers.h: Removed prototype for num2long.
2500 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2502 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2503 array as second arg.
2504 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2505 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2506 * gh.h: Updated and added prototypes.
2508 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2510 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2512 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2514 * guile-snarf.in: Never generate an empty file. (Thanks to
2517 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2518 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2519 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2520 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2521 gh_new_procedure5_0): Specify argument types, to appease C++
2522 compilers. (Thanks to Brad Bowman.)
2524 Bug reports from Russ McManus:
2525 * guile-snarf.in: If the CPP environment variable is set, use that
2526 as the C preprocessor, instead of the preprocessor autoconf
2528 * snarf.h (SCM_PROC): Cast the function pointer passed to
2529 scm_make_gsubr, to satisfy C++.
2531 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2532 Use the handler passed, instead of ignoring it and using
2533 gh_standard_handler. (Thanks to Etienne Bernard.)
2535 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2537 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2540 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>
2542 * __scm.h, alist.c, async.c, async.h, backtrace.h, chars.c,

2560 * script.c (scm_compile_shell_switches): Define
2561 use-emacs-interface in the root module, so the repl code can see
2562 it. See today's change to top-repl in ice-9/boot-9.scm.
2564 * filesys.c (set_element, get_element): Make sure that `element'
2565 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2566 Boekemeier and Jorgen "forcer" Schaefer.)
2568 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2570 * chars.c (scm_charnames): In ASCII character name table, make
2571 newlines print as #\newline by default, not #\nl.
2573 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2574 alphabetical order. Oh thrills. But it helps me know how far
2575 along in the compilation I am.
2576 * Makefile.in: Regenerated.
2578 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2580 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2581 #bytes(...) to #y(...), and syntax for short vectors from
2582 #short(...) to #h(...). This may seem nutty, but, like the other
2583 uniform vectors, byte vectors and short vectors want to have the
2584 same print and read syntax (and, more basic, want to have read
2585 syntax!). Changing the read syntax to use multiple characters
2586 after the hash sign breaks with the conventions used in R5RS and
2587 the conventions used for the other uniform vectors. It also
2588 introduces complexity in the current reader, both on the C and
2589 Scheme levels. (The Right solution is probably to change the
2590 syntax and prototypes for uniform vectors entirely.)
2592 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2594 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2595 (Thanks to Jorgen "forcer" Schaefer.)
2596 * ports.h (SCM_NOFTELL): New flag.
2597 * fports.c (local_fgets): If it's set, use the generic fgets.
2598 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2600 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2602 * script.c (scm_compile_shell_switches): Add handling of -q switch
2603 (inhibit loading of user init file).
2604 (scm_shell_usage): Add usage text for -q switch.
2605 (scm_compile_shell_switches): Always load user init file first if
2606 it is loaded at all.
2608 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2610 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2611 and is now broken under NetBSD. I can't fathom what it's trying
2612 to do, so I've replaced it with something that I do understand,
2613 which seems to work, and which isn't broken on NetBSD. "Progress?
2614 You Decide." (Thanks to Perry Metzger.)
2616 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2617 signed/unsigned comparison.
2619 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2621 Warning fixes from Greg Harvey:
2622 * unif.c (scm_array_set_x): initializer for pos
2623 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2624 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2625 initializers for field_type, since EGCS so desparately wants to
2627 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2628 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2629 when GUILE_DEBUG is defined.
2630 * dynwind.h (scm_wind_chain): Same.
2631 * ports.h (scm_pt_size, scm_pt_member): Same.
2632 * print.h (scm_current_pstate): Same.
2633 * procs.h (scm_make_cclo): Same.
2635 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2637 Handle short and long long uniform arrays properly. (Thanks to
2639 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2640 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2641 scm_tc7_llvect (long long vectors).
2643 Change the way libguile and boot-9.scm are timestamped, to try to
2644 get rid of these spurious mismatch warnings. Now both
2645 libguile/versiondat.h and ice-9/version.scm are generated directly
2646 by the configuration process, rather than having version.scm
2647 generated directly, and libguile/versiondat.h generated by the
2648 Makefile, which is generated by configure. It seems that
2649 sometimes the Makefile would change, but versiondat.h depends on
2650 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2651 * Makefile.am (versiondat.h): Target removed; this is generated
2652 directly by the configure script now.
2653 (BUILT_SOURCES): Remove versiondat.h.
2654 * versiondat.h.in: New file, transformed by the configure script
2656 * Makefile.in: Regenerated.
2658 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2659 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2660 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2661 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2662 if we want to use them in a header file some day, we can. (Thanks
2663 to Michael Livshin.)
2665 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2666 SCM numbers, so we won't have rollover problems; the range of a
2667 signed long in milliseconds is about 25 days. (Thanks to Karl
2670 Don't redefine sleep and usleep; fix this problem now.
2671 * coop.c (sleep, usleep): Remove declarations; we don't use or
2672 redefine these any more.
2673 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2674 job of usleep and sleep in a thread-friendly way. We can use
2675 these in the rest of Guile. Define versions for systems both with
2676 and without iselect.
2677 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2678 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2679 we're just using it, not redefining it, we can use a K&R style
2681 (sleep): Declare this, too, if the system hasn't.
2682 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2683 scm_uthread_sleep if they're available; otherwise, just call the
2685 * scmconfig.h.in: Regenerated.
2687 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2689 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2691 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2693 * threads.c: Doc fix.
2695 The argument type of usleep varies from system to system,
2696 as does the return type. We really shouldn't be redefining usleep
2697 at all, but I don't have time to clean that up before the 1.3.
2698 release. It's on the schedule for afterwards. (Thanks to Julian
2700 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2702 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2703 * scmconfig.h: Regenerated.
2705 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2706 right way to handle system variation. Autoconf's approach is the
2708 * simpos.h (scm_software_type): Declaration deleted.
2710 * script.c (scm_find_executable): Don't test if unix is #defined
2711 here; first, NetBSD doesn't #define it, and second, it's the wrong
2712 way to go about these things. (Thanks to Perry Metzger.)
2713 (dld_find_executable): Delete this MSDOS support code. This isn't
2714 the way we want to support this; it needs to be rethunk at a
2717 * genio.c (scm_do_read_line): Don't just politely check that the
2718 line was either non-empty or EOF. Abort if it's empty and not
2721 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2723 * scmconfig.h.in: Regenerated.
2725 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2728 * genio.c (scm_do_read_line): Count lines correctly when the file
2729 doesn't end in a newline.
2731 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2733 * genio.c (scm_do_read_line): Maintain the line count correctly.
2734 (Thanks to Harvey J. Stein and Greg Harvey.)
2736 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2739 * numbers.c (big2str): Protect t from garbage collection until
2740 we're done. (Thanks to Gary Houston.)
2742 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2744 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2746 * Makefile.in: Regenerated.
2748 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2749 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2752 Do magic to mix reads and writes on stdio FILE-based ports.
2753 (Thanks to Christian Lynbech.)
2754 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2756 (pre_read, pre_write): New functions.
2757 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2758 local_fputs): Call them.
2759 (local_fflush): Mark the port as ready for reading and writing.
2760 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2761 flags on new port objects. This might not be accurate --- who
2762 knows what state the FILE * is in when we get it --- but it won't
2763 do extraneous calls to fflush or fseek, so it's no worse than the
2764 behavior before this change.
2765 * ports.h: Add comment.
2767 Centralize the creation of port objects based on stdio FILE * in
2768 fports.c; don't just throw them together anywhere.
2769 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2770 what the rest of Guile wants. Don't set the revealed count;
2771 that's only appropriate for stdin, stdout, stderr.
2772 (scm_standard_stream_to_port): This function does set the revealed
2774 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2775 not scm_stdio_to_port.
2776 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2777 * fports.c (scm_open_file): Same.
2778 * posix.c (scm_pipe): Same.
2779 * socket.c (scm_sock_fd_to_port): Same.
2780 * ioext.c (scm_fdopen): Same.
2781 (scm_freopen): Moved from here to...
2782 * fports.c (scm_freopen): ... here. This is really something that
2783 munges the internals of an fport, so it should go here.
2784 * fports.h (scm_stdio_to_port): Adjust prototype.
2785 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2786 * ioext.h (scm_freopen): Prototype removed.
2788 * filesys.c (set_element, get_element): This can work on both pipe
2789 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2792 * scmconfig.h.in: Regenerated.
2794 Change the definition of the functions in scm_ptobfuns so that
2795 they get passed the port object, not the port's stream.
2796 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2797 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2798 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2799 Pass the port itself to the scm_ptobs function.
2800 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2801 scm_generic_fgets): Same.
2802 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2803 getc_void_port, fgets_void_port, close_void_port): Just change the
2804 argument names; these functions don't really do anything.
2805 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2806 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2807 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2808 Also, use prototyped definitions, and get rid of the extra
2810 (scm_fptob, scm_pipob): We don't need casts here any more.
2811 * strports.c (prinstpt): Use prototype declarations.
2812 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2813 and use SCM_STREAM to get the string info. Also, use prototyped
2814 definitions, and get rid of the extra declarations.
2815 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2818 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2819 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2821 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2822 scm_fgets, for consistency.
2823 (scm_fptop, scm_pipob): References updated.
2825 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2827 Include the source location in error messages for scripts.
2828 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2829 stack is still there when we catch the error.
2830 * throw.c (handler_message): If we are handling an error with a
2831 message, then put together the proper arguments and call
2832 scm_display_error, instead of scm_display_error_message. That
2833 displays source location, if it can find it.
2835 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2837 * gc.c (scm_unprotect_object): Change this so that calls to
2838 scm_protect_object and scm_unprotect_object nest properly.
2839 (scm_protect_object): Doc fixes.
2841 * strings.c (scm_string_set_x): Require the argument to be a
2842 writable string, not a substring or a symbol.
2843 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2844 (Thanks to John Redford and Charbel Jacquin.)
2846 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2848 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2850 * eval.c (safe_setjmp): Remove this misunderstanding.
2851 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2854 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2856 * libguile.h: Mark these as C declarations, for compilation by C++
2859 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2860 __cplusplus clause. I seriously doubt this ever worked the way
2861 the author seems to have intended.
2863 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2865 Utterly needless cleanups to hopelessly messy code.
2866 * ports.c: Doc fixes.
2867 (scm_fflush): Moved to ...
2868 * genio.c (scm_fflush): ... here, amongst all the other port
2869 method invocation functions.
2870 * genio.h, ports.h: The prototype moves too.
2872 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2874 * backtrace.c (display_error_body): The current frame does not
2875 always have a parent frame; consider a function called directly
2876 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2879 * alloca.c (alloca): Undo yesterday's changes, and simply call
2880 malloc directly for storage, and abort if we don't get what we
2881 want. The situation is much simpler --- just call malloc. Emacs
2882 has bizarre/evil requirements (signal handlers might malloc unless
2883 you set this global flag, so you have to set the flag around all
2884 calls to malloc) which we are certainly not going to conform to,
2885 so we can do the simple and obvious thing.
2887 * coop.c (coop_condition_variable_wait): Make this function
2888 static. It's only useful internally --- you should never just
2889 wait on a condition variable.
2890 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2892 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2894 * unif.c (scm_array_set_x): Accept any kind of number as an
2895 element for a uniform vector of doubles. This is more consistent
2896 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2898 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2899 works; I can't conveniently test it myself. (Thanks to Dvid
2900 Tillman for the bug report.)
2902 * init.c: Doc fixes.
2904 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2905 from here, not from scm_compile_shell_switches (which is a pretty
2906 dumb place to do it).
2907 (scm_load_startup_files): New function.
2908 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2909 * script.c (scm_compile_shell_switches): Don't load the startup
2911 (scm_ice_9_already_loaded): Variable moved.
2912 * init.c (scm_load_startup_files): Prototype for new function.
2913 * gh_init.c (gh_enter): Doc fix.
2915 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2917 Some anti-warning changes from Greg Harvey.
2918 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2919 warnings when it doesn't understand our NORETURN declarations in
2921 * posix.c (scm_mknod): Similar.
2923 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2925 * posix.c (scm_getpwuid): If we can't find an entry, return our
2926 own message, instead of using scm_syserror --- the getpwMUMBLE
2927 functions don't set `errno' to anything interesting.
2929 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2931 Get rid of warnings from the cooperative threading system.
2932 * threads.h (scm_single_thread_p, scm_yield,
2933 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2934 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2935 scm_wait_condition_variable, scm_signal_condition_variable): Add
2936 prototypes for these Scheme-visible functions.
2937 * coop-defs.h (coop_next_runnable_thread,
2938 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2939 Prototypes for these here, even though they're from iselect.c.
2940 (coop_condition_variable_wait, coop_join): Add prototypes.
2941 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2942 scm_threads_free_condvar): Make these smob functions static.
2943 * coop-threads.h (coop_init): Give this a real prototype.
2944 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2945 (coop_next_runnable_thread): No need to provide prototype; it's in
2948 * scmconfig.h.in: .detarenegeR
2950 * iselect.c, threads.c: Doc fixes.
2952 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2954 * Makefile.in: Regenerated with a patched automake, to get
2955 dependency generation right when using EGCS.
2957 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2958 warning. (Thanks to Robert Pluim.)
2960 * inet_aton.c (inet_aton): Reassure the compiler that the
2961 arguments to the <ctype.h> macros are all unsigned characters, not
2964 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2966 Getting rid of more warnings...
2967 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2968 today's change to ../configure.in.
2969 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2970 * scmconfig.h.in: Regenertaded.de.,.__
2971 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2972 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2975 * readline.c: Doc fix.
2976 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2977 * readline.h (scm_filename_completion_function): Add prototype.
2978 (scm_init_readline): Make this into a prototype.
2980 * readline.c (scm_filename_completion_function): Use SCM_PROC to
2981 declare this, instead of calling scm_make_subr manually.
2983 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
2985 * readline.h (scm_init_readline): Add prototype for this.
2986 (scm_init_readline): Make this a real prototype.
2988 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
2990 Warning fixes from Maciej Stachowiak:
2991 * backtrace.h (scm_display_application, scm_backtrace): Add
2993 * debug.c (scm_m_start_stack): Make this function static.
2994 * fluids.h (scm_fluid_p): Add prototype.
2995 * procprop.c (scm_i_procedure_arity): Make this function static.
2996 * regex-posix.c (scm_regexp_error_msg): Make this function static.
2997 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
2998 * root.h (scm_dynamic_root): Add external prototype.
2999 * scmsigs.h (scm_usleep): Add external prototype.
3000 * script.h (scm_init_script): Use prototype, not K&R decl.
3001 * stacks.h (scm_stack_id): Add external prototype.
3002 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3004 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3006 * gh.h: took out the definitions of vset and vref, since they are
3007 replaced by the proper vector routines that correspond to the R4RS
3010 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3012 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3013 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3014 third argument, a C expression that should result in a SCM value,
3015 which is used to initialize the variable. Reimplemented
3016 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3019 * version.h (scm_libguile_config_stamp): Add prototype.
3020 (From Maciej Stachowiak.)
3022 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3024 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3025 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3027 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3029 * print.c (scm_iprin1): Rather than having one i, and using it in
3030 several places, declare a fresh i local to each block where it is
3031 used, and give it a signedness appropriate to its use in each case.
3032 (scm_iprlist): Same.
3034 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3035 comparison warnings.
3037 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3038 signed/unsigned clashes.
3040 * posix.h (scm_tmpnam): Added prototype.
3042 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3043 scm_make_subclass_object): Add external prototypes.
3045 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3046 comparison is okay here.
3048 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3050 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3051 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3053 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3056 * load.c (swap_port): Make this function static.
3058 * load.c (scm_search_path): Make max_path_len and max_ext_len
3059 unsigned, since they're compared against string sizes.
3061 * load.c (init_build_info): Make i unsigned.
3063 * ioext.h (scm_read_line): Add prototype.
3065 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3066 scm_hash_fn_remove_x): Make hash bucket index local variable k
3067 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3068 accurately as possible.
3070 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3071 comparisons, and range checking to make sure those casts are
3074 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3075 signed/unsigned comparisons.
3077 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3078 avoid signed/unsigned comparisons.
3079 * smob.h (scm_numsmob): Change extern declaration to match.
3081 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3082 avoid signed/unsigned comparisons.
3083 * ports.h (scm_numptob): Change extern declaration to match.
3084 (scm_current_load_port, scm_set_port_line_x,
3085 scm_set_port_column_x): New prototypes.
3087 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3088 test code, and it causes warnings.
3090 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3091 gh_uniform_vector_ref): Added prototypes.
3093 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3094 debugging support unconditionally. That's backtrace.c, stack.c,
3095 debug.c, and srcprop.c.
3096 (EXTRA_libguile_la_SOURCES): Omit those from here.
3097 * Makefile.in: Regenerated.
3099 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3101 * options.c (scm_options): Bugfix: Allow empty list of options!
3103 * debug.c, debug.h (scm_single_step): Removed.
3104 (scm_with_traps): New procedure. This procedure could easily be
3105 written in Scheme but needs to be highly optimized.
3107 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3109 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3110 Check SCM_TRAPS_P before trapping.
3112 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3114 Changes to avoid signed/unsigned comparison warnings.
3115 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3116 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3117 so they can have appropriate types for each application. Make i
3118 signed. Use initializers in some spots. I'll probably pay for
3120 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3121 (scm_must_realloc): Make nm unsigned.
3122 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3123 (scm_init_storage): Use prototype-style definition, and make the
3125 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3126 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3128 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3129 avoid signed/unsigned comparison warnings, and because the return
3130 value of readlink may be -1. Don't bother casting the third
3131 argument to readlink.
3133 * filesys.c (scm_dirname, scm_basename): Move these to their own
3134 page, at the end of the file.
3135 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3137 * eval.h (scm_eval_options_interface): Add external prototype for this.
3138 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3140 * eval.c (scm_lookupcar1): Make this static.
3142 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3143 Make these prototype declarations, not K&R-style.
3145 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3146 unsigned comparison warning.
3148 * appinit.c: File removed. It had a single function in it, empty,
3149 whose reason for existence is explained in no documentation or
3150 comment. I think it's there as a default for some Tcl-style
3151 initialization, but Tcl abandoned that approach a while ago.
3152 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3153 (BUILT_SOURCES): Remove appinit.x.
3154 * Makefile.in: Regenerated.
3156 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3158 * Makefile.in: Regenerated using the last public version of
3159 automake, not the hacked Cygnus version.
3161 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3163 Remove Totoro kludge.
3164 * Makefile.in, scmconfig.h.in: Regenerated.
3165 * init.c, readline.c: Don't check if TOTORO is #defined.
3167 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3169 * Makefile.am: Adjust for new thread configuration system.
3170 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3171 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3173 (THREAD_LIBS): Definition deleted; automake will generate such
3174 things automatically.
3175 * Makefile.in: Regenerated.
3177 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3179 Simplify smob and port marking; set the mark bit in the generic
3180 marking code, and make marker routines only responsible for
3181 turning up outgoing pointers.
3182 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3183 before calling the marking function. Don't call the marking
3184 function if it's zero.
3185 * markers.c (scm_mark0): Just return #f. This function isn't
3186 necessary at all now, but it's harmless to call it. We'll leave
3187 it in so other folks' code doesn't croak at link time.
3188 (scm_markcdr): Don't call SCM_SETGC8MARK.
3189 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3190 * dynl.c (mark_dynl_obj): Same.
3191 * root.c (mark_root): Same.
3192 * srcprop.c (marksrcprops): Same.
3193 * unif.c (markra): Same.
3194 * variable.c (scm_markvar): Same.
3195 * ports.c (scm_markstream): Same.
3196 (void_port_ptob): Specify zero for our marking function.
3197 * debug.c (debugobjsmob): Same.
3198 * dynwind.c (guardsmob): Same.
3199 * filesys.c (dir_smob): Same.
3200 * fluids.c (fluid_smob): Same.
3201 * fports.c (scm_fptob, scm_pipob): Same.
3202 * mallocs.c (mallocsmob): Same.
3203 * regex-posix.c (regex_t_smob): Same.
3204 * smob.c (freecell, flob, bigob): Same.
3205 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3206 * throw.c (jbsmob, lazy_catch_funs): Same.
3208 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3210 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3211 scm_copy_tree on code in order not to let memoized code to leak
3212 out. Thus, scm_copy_tree needs to copy vectors as well since
3213 quasiquote can introduce evaluated code also inside vector
3216 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3218 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3220 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3221 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3224 * unif.c: Say that ivect and uvect are of type signed and unsigned
3225 long instead of int in commentary so that it correctly describes
3228 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3230 * stime.c: Removed declaration of strptime. (It should be
3231 declared by the system headers. If it turns out that some systems
3232 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3234 * stime.h: Renamed TIMEH --> STIMEH
3236 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3237 to increase portability, don't use structure assignment.
3238 (Thanks to Nicolas Neuss.)
3240 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3242 (finalize_fd_sets): Added empty statement after last case label.
3243 (Thanks to Nicolas Neuss.)
3245 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3248 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3250 * init.c, readline.c: OK, I won't have these readline.x bug
3251 reports anymore. We've had them since April. The current reason
3252 is a completely unintelligible failure of totoro.red-bean.com to
3253 do the test for rl_getc_function in libreadline correctly. This
3254 kludge overrides the test if we're on totoro so that the snapshot
3255 generation process can work.
3257 * readline.c: Define a strdup replacement if not existent on system.
3259 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3261 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3262 This change makes scm_make_vector R5RS compatible. We cannot keep
3263 the third argument since people want to be able to deduce the form
3264 of the C function call only by looking at R5RS. (At the same time
3265 we have removed some unnecessary complexity!)
3267 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3268 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3269 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3270 argument in call to scm_make_vector.
3272 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3274 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3275 This macro is useful in applications.
3277 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3279 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3280 (scm_parse_path, scm_search_path): New Scheme level procedures.
3282 * load.h (scm_internal_parse_path, scm_parse_path,
3283 scm_search_path): Declared.
3285 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3287 * filesys.c (dirname, basename): New procedures.
3289 * init.c (scm_boot_guile_1): Removed condition around
3292 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3293 new data type (guards) for representation of C level guards and
3294 data on the wind chain.
3295 (scm_internal_dynamic_wind): New function.
3297 * dynwind.h: Declare scm_internal_dynamic_wind.
3299 * root.h (scm_root_state): Added scm_cur_loadp.
3301 * root.c (mark_root): Added comment about cur_loadp.
3303 * load.c: #include "dynwind.h";
3304 (scm_primitive_load): Use scm_inner_dynamic_wind to update
3307 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3309 * ports.c (current-load-port): New procedure.
3311 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3313 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3314 not a tty, return #f.
3316 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3317 to Julian Satchell and Roland Kaufmann.)
3319 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3320 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3322 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3324 * debug.h, debug.c (scm_start_stack): New function. Implements
3325 the guts of old scm_m_start_stack.
3327 * debug.c (scm_m_start_stack): Use scm_start_stack.
3329 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3330 start_stack and restart_stack. (These have static scope.)
3332 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3334 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3335 readline functions to come in release 2.3. (Thanks to Chet
3337 (handle_errors): Use the above functions.
3339 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3341 * readline.c: Improvements for readline support: Handle errors
3342 better; Implement before-read-hook.
3344 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3346 * init.c (scm_boot_guile_1), readline.c: Test for
3347 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3348 assure that we have version >= 2.1.)
3350 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3352 * readline.c (scm_readline): Defer interrupts while we're calling
3355 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3356 away the string to add_history.
3357 (completion_function): Do completion for readline. (Thanks to
3359 (scm_filename_completion_function): New procedure: Filename
3361 (current_input_getc): New function. Use this one instead of
3362 standard getc from readline.
3364 * throw.c, throw.h (scm_handle_by_throw): New function: This
3365 handler throws errors to next handler on the dynwind chain.
3367 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3369 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3372 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3374 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3376 (scm_procedure_properties): Modified to return arity together with
3378 (scm_procedure_property): Added the read-only property `arity'.
3379 (scm_set_procedure_property_x): It is an error to set the `arity'
3382 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3383 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3385 * procprop.h (scm_sym_arity): New symbol.
3387 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3388 to set the dispatch procedure of an operator or entity object.
3390 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3391 Made procedure slots read-only.
3393 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3394 scm_tcs_cons_gloc case in zero args switch; Fixed args
3395 construction for operators in scm_tcs_cons_gloc case in two args
3398 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3400 * fluids.c: Removed use of assert.h (in order to avoid
3403 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3405 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3407 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3408 change makes the evaluator safer at the cost of evaluation speed.
3409 It handles the case when the user has added a non-immediate
3410 improper end of the application form, e.g., `(+ 0 . x)'.
3411 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3412 minimize the extra cost as much as possible. The new code is
3413 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3414 problem with structs planted directly in the code (e.g. by a
3415 macro). This no longer causes segmentation fault. (Thanks to
3418 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3419 arg `proc' in order to be able to throw errors; New argument
3422 * Removed extra #include "debug.h"
3424 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3426 * scmsigs.c: Declare usleep as returning void on some systems.
3427 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3430 * coop.c (usleep): Return void on some systems.
3432 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3434 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3436 * coop.c: Changed return type of usleep to int.
3438 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3439 isn't found in the OS.
3441 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3442 isn't enabled. (Thought that I had made this change ages ago...)
3444 * iselect.c: Declare bzero if not defined by OS.
3446 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3448 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3449 condition. (Thanks to John Tobey.)
3451 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3452 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3455 * __scm.h: Start the long-term project of moving to POSIX threads.
3456 Phase 1: Classification of all critical sections.
3457 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3458 for A sections. (See comments in __scm.h for details.)
3460 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3461 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3463 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3465 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3466 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3467 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3468 dependencies on $(srcdir)/Makefile.in
3469 $(top_builddir)/config.status in order to avoid circularity.
3471 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3472 from argc if argc was 0 initially.
3474 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3475 in generation of libpath.h.
3477 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3479 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3480 libguile from 2 to 3.
3482 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3484 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3486 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3488 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3489 scm_set_port_column_x, scm_port_filename,
3490 scm_set_port_filename_x): Removed optional arguments. Added
3491 proper argument checking.
3493 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3494 stack size in machine words.
3496 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3497 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3498 to Ole Myren Röhne.)
3500 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3502 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3503 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3505 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3508 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3509 procedure apply: Copy argument lists before pushing them unto the
3510 environment so that the environment won't get mutated due to
3511 manipulation of procedure arguments. This should perhaps be
3512 regarded as a temporary solution until someone finds a more
3513 efficient one. (Thanks to Maciej Stachowiak.)
3515 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3517 * script.c (scm_compile_shell_switches): Use "guile" as default
3518 zero arg if argc is NULL.
3520 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3522 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3523 is zero. (Thanks to Dirk Herrmann.)
3525 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3527 * ports.c (scm_add_to_port_table): First line is now line 0
3528 (was 1). (Interface changed according to suggestion by Per
3531 * backtrace.c (display_header): Add 1 to line and column numbers
3532 when presenting them to the user.
3534 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3535 from debug.c --> eval.c
3537 * eval.h, eval.c (scm_eval_options_interface): New options
3539 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3540 i.e. stacks for new threads.
3542 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3544 * eval.c (unsafe_setjmp): Removed with #if 0.
3546 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3549 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3550 to avoid compiler warnings.
3552 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3554 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3556 * throw.c (handler_message): Print message on current error port
3557 instead of default error port. (Thanks to Maciej Stachowiak.)
3559 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3561 * ports.c (scm_add_to_port_table): allocate in units of
3562 struct scm_port_table *, not struct scm_port_table.
3563 * posix.c (scm_close_pipe): remove the port from the port table
3565 Thanks to Rob Engle for both fixes.
3567 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3569 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3570 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3572 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3574 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3576 * backtrace.c (display_error_body, display_backtrace_body),
3577 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3578 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3579 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3580 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3583 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3584 don't receive the jmpbuf arg anylonger.
3585 (scm_catch): Don't accept a #f tag.
3586 (scm_throw): Check that key is a symbol.
3587 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3589 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3591 * async.c (async_pending): Removed declaration.
3593 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3595 * dynwind.c (scm_wind_chain): New debug function.
3597 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3598 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3599 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3600 extra layer of functions around the body and handler of a thread.
3601 This extra layer makes sure that the handler is called in the
3602 dynamic context of the surround (= empty dynwind list), but under
3603 the *dynamic root* of the body. We can not use the dynamic root
3604 of the surround since that root belongs to another thread => stack
3605 is not handled correctly. It may seem ugly to use this extra
3606 layer, but the extra cost in terms of execution time is really
3607 negligible compared to the total amount of time required to create
3608 a thread, and it would reduce maintainability to duplicate the
3609 crucial and complicated steps performed by cwdr.
3611 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3612 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3613 get re-enabled. The important effect of this is that interrupts
3614 are blocked during thread switching so that thread data structures
3615 don't risk getting messed up by an unfortunate signal.
3616 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3617 seems to do more aggressive optimization which actually move
3618 instructions around in these macros in a fatal way. Therefore:
3619 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3620 just superstitious...)
3621 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3622 This macro should be used instead of SCM_ASYNC_TICK since the
3623 latter doesn't do context switches any more.
3625 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3626 instead of SCM_ASYNC_TICK.
3628 * coop.c, iselect.c: Since thread switches are now performed with
3629 interrupts masked, we can't use the old mechanism of delivering
3630 signals immediately when they arrive. Signals must instead be
3631 delivered when the asyncs run *after* the end of the critical
3632 section in scm_internal_select. But this also means after context
3633 switch so that the signal will be delivered to a different thread.
3634 To avoid this, I have changed the protocol of
3635 coop_wait_for_runnable_thread and friends so that they are allowed
3636 to return the original thread. So, if a signal arrives during
3637 scm_internal_select, we won't any longer be forced do a context
3638 switch, but can remain in the same thread and deliver the signal
3641 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3642 scm_asyncs_pending and made it global.
3644 * iselect.c: Small fixes.
3646 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3647 coop_condition_variable_init, coop_condition_variable_wait,
3648 coop_condition_variable_signal): Changed return type from `void'
3649 to `int'. This is to adhere closer to the pthreads interface.
3650 This, in turn, is part of an attempt to provide C versions of the
3651 mutex and condition variable primitives which can be part of a
3652 frontend to COOP or pthreads.
3654 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3655 coop_condition_variable_destroy): New functions.
3657 * coop-threads.c (scm_wait_condition_variable): Use
3658 coop_condition_variable_wait_mutex.
3660 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3661 Definitions moved to coop-defs.h.
3663 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3664 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3665 scm_cond_destroy): New C interface to mutecis and cond vars.
3667 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3669 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3671 * iselect.c: Now several threads can wait on the same file
3672 descriptor. The behaviour is compatible with OS select: All
3673 threads waiting for the fd return with the same status.
3675 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3677 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3678 Can spawn a thread from application C code.
3680 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3682 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3683 gh_doubles2scm): New functions.
3685 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3687 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3688 commented-out version of gh_eval_str()
3690 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3692 * socket.c (scm_bind): free soka after use.
3694 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3696 * stime.c (tzvar): new variable.
3697 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3698 avoid memory leaks when allocating.
3700 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3702 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3705 * gc.c, tags.h: Doc fixes.
3707 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3709 * eval.c (macro-eval!): Removed. This function was a design bug.
3710 It allowed memoized code to leak out to the scheme level. Most
3711 things that you could do with `macro-eval!' can be done with
3714 1997-12-20 Tim Pierce <twp@skepsis.com>
3716 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3717 scm_fgets now depends on ftell(3) to know how many bytes were
3720 1997-12-15 Tim Pierce <twp@skepsis.com>
3722 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3723 dealing with strings.
3725 1997-12-13 Tim Pierce <twp@skepsis.com>
3727 Make %read-line more suitable for implementing read-line efficiently.
3728 * ioext.c (scm_read_line): Strip the terminating newline from a
3729 string, and return a cons of the string and its terminator.
3731 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3732 of the string that is read is stored in this memory location.
3733 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3734 * genio.c, genio.h (scm_do_read_line): Update caller.
3735 * ports.h (scm_ptobfuns): Update typedef.
3736 * fports.c (scm_fptob, scm_pipob): Update struct.
3738 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3740 * filesys.c (set_element): Return file descriptor.
3741 (fill_select_type): Return the highest file descriptor.
3742 (scm_select): Tell select about the highest file descriptor. On
3743 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3744 Therefore the extra overhead for calculating the maximum fd seems
3745 to be more than compensated. Is this correct? In any case,
3746 scm_internal_select will be much faster with this info.
3747 (scm_select, fill_select_type, set_element): Don't accept any kind
3748 of object in the file descriptor list or vector.
3750 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3752 * iselect.c (finalize_fd_sets): Bugfix.
3754 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3756 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3757 when using scm_internal_select (since we might switch to another
3760 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3762 * simpos.c (scm_system): always define: use sysmissing if not
3763 available. Check for HAVE_SYSTEM instead of _Windows (does
3764 Windows lack system or does it have an unusable one?).
3765 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3766 Let the argument be optional: if not supplied, call system(NULL).
3768 * ports.c (scm_close_port): relax the type check from OPPORTP to
3769 PORTP; closing a closed port is allowed.
3771 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3773 * fports.c (scm_fgets): Return if the last char in a chunk is
3774 newline. When fgets returns a string whose length is `size-1', it
3775 is ambiguous whether a whole line was retrieved, so we must check
3776 explicitly whether a line terminator is present.
3778 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3780 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3781 before taking the CDR. (Thanks to Harald Meland.)
3783 * filesys.c (scm_stat): Slightly optimized.
3785 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3787 * ports.c (scm_close_port): Make sure the port is open before
3790 * guile-snarf.in: Pass args through to gcc in a way that preserves
3791 whitespace boundaries. (Thanks to Greg Badros.)
3793 1997-12-02 Tim Pierce <twp@skepsis.com>
3795 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3796 statement. (Thanks to Doug Evans for pointing this out.)
3798 1997-12-01 Tim Pierce <twp@skepsis.com>
3800 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3802 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3804 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3805 errno macro expansion of this field name. (errno is a C
3806 preprocessor macro on some systems.)
3808 1997-11-29 Tim Pierce <twp@skepsis.com>
3810 * iselect.c: Doc fix.
3812 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3814 * init.c (scm_start_stack): Removed initialization of
3815 scm_the_last_stack_var.
3817 * backtrace.h: Declare scm_the_last_stack_var.
3819 * backtrace.c: Define scm_the_last_stack_var.
3821 * root.c (mark_root): Don't mark the_last_stack_var.
3823 * root.h (scm_root_state): Removed the_last_stack_var.
3825 * throw.c: Added #include "fluids.h"
3826 (ss_handler): `the-last-stack' is now a fluid.
3828 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3829 --> the_last_stack_fluid.
3831 * backtrace.c: Added #include "fluids.h"
3832 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3833 (scm_backtrace): `the-last-stack' is now a fluid.
3835 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3836 after scm_init_fluids.
3838 1997-11-28 Tim Pierce <twp@skepsis.com>
3840 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3842 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3843 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3845 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3847 * iselect.c (coop_next_runnable_thread,
3848 coop_wait_for_runnable_thread): Disable interrupts so that no
3849 async is executed before a potential error_revive.
3850 (scm_internal_select): Disable interrupts during the parts of the
3851 code which manipulate the sleep queue and the file descriptors.
3853 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3855 * Makefile.am: Added iselect.c and iselect.h.
3857 * coop.c (coop_qinit): Initialize fields used by
3858 scm_internal_select.
3859 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3860 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3861 replacement in iselect.c.
3862 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3863 coop_join): If GUILE_ISELECT enabled, use
3864 coop_wait_for_runnable_thread instead of
3865 coop_next_runnable_thread.
3866 (usleep, sleep): New replacements for system functions if
3867 GUILE_ISELECT is enabled.
3869 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3871 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3873 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3874 iselect.h. Implement Scheme level `select' using
3875 scm_internal_select. (See NEWS.)
3877 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3879 * init.c: Call scm_init_iselect.
3881 * iselect.h, iselect.c: New files. Implements
3882 scm_internal_select. (See NEWS.)
3884 1997-11-27 Tim Pierce <twp@skepsis.com>
3886 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3887 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3888 and scm_must_free, since ultimately the string returned will be copied
3889 by scm_makfrom0str anyway. Also, read any characters that may have
3890 been pushed onto the port with scm_ungetc.
3891 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3892 * ioext.c (scm_read_line): Free string after Guilifying it.
3893 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
3895 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3897 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3899 * gh.h: Safely wrap prototypes for c++ usage.
3901 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3903 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3904 gh_repl (argc, argv).
3906 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3908 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3909 and to invoke scm_shell().
3910 (gh_launch_pad): took out the loading of boot-9.scm from here,
3911 since it is probably best to let the user control that. In fact,
3912 gh_repl() now invokes scm_shell() which does that.
3914 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3916 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3919 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
3921 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
3922 yesterday's underscore patch. (Thanks to Marius Vollmer for
3925 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
3927 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
3928 DLSYM_ADDS_USCORE is not defined.
3930 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
3932 * gh_data.c (gh_uniform_vector_length):
3933 (gh_uniform_vector_ref): started implementing the uniform types in
3936 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3938 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3939 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3941 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3943 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3944 configure.in was changed).
3946 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3948 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3949 * Makefile.in: Regenerated.
3951 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3953 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3954 OPORT is an `open' port, not an output port.
3956 * filesys.c (scm_close, set_element, get_element, scm_chown,
3957 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
3958 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
3959 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
3960 scm_close_port, scm_port_line, scm_set_port_line_x,
3961 scm_port_column, scm_set_port_column_x, scm_port_filename,
3962 scm_set_port_filename_x, scm_port_mode,
3963 scm_close_all_ports_except, scm_set_current_output_port,
3964 scm_set_current_error_port): Likewise
3965 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3966 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
3968 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
3969 * backtrace.c (display_backtrace_body): Likewise
3970 * fports (scm_setvbuf): Likewise
3971 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
3972 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
3973 scm_getpeername, scm_send, scm_sendto): Likewise
3974 * unif.c (scm_uniform_array_write): Likewise
3976 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
3978 Minor problems with substring-related tag changes.
3979 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
3980 exactly what we want to leave in to detect substrings.
3981 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
3982 * tags.h: Fix diagrams and comments describing the S tag bit;
3983 remove vestigial remarks about the D tag bit.
3984 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
3985 * strings.c: Formatting tweaks.
3987 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
3988 variable first; then SCHEME_LOAD_PATH, with a warning message.
3989 (scm_parse_path): New function.
3990 * script.c: Doc fixes.
3992 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
3994 Readline support, from Daniel Risacher.
3995 * readline.c, readline.h: New files.
3996 * init.c: #include "readline.h".
3997 (scm_boot_guile_1): Call scm_init_readline, if we have it.
3998 * Makefile.am (libguile_la_SOURCES): Include readline.c.
3999 * Makefile.in: Regenerated.
4000 * scmconfig.h.in: Regenerated, after change to ../configure.
4002 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4004 * gh.h: gh_vector_set -> gh_vector_set_x
4006 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4008 * gh_data.c (gh_vector_set_x): changed name to make it consistent
4009 with the ! -> _x mapping when going from Scheme to C.
4011 1997-10-19 Mark Galassi <rosalia@cygnus.com>
4013 * gh.h (gh_reverse):
4021 (gh_assoc): added these gh_ functions implemented as macros.
4023 * gh_predicates.c (gh_null_p):
4024 (gh_string_equal_p): added these two missing predicates.
4026 * gh_list.c (gh_append):
4031 (gh_set_cdr_x): added these routines as I go through and try to
4032 complete the picture R4RS functions that should be mirrored in the
4035 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4037 * tags.h (scm_tc7_substring): Changed the comment and code to
4038 conform with the changes below. Folks! We have suddenly two new
4039 free tc7 codes!!! Jummy, jummy!
4041 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
4043 * Makefile.in: Rebuilt.
4044 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
4046 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
4047 * unif.c (scm_vector_set_length_x): Don't handle multibyte
4049 * tag.c (scm_utag_mb_string, scm_utag_mb_substring): Removed.
4050 (scm_tag): Don't handle multibyte strings.
4051 * read.c: Don't include mbstrings.h.

4053 * kw.c: Don't include mbstrings.h.
4054 * init.c: Don't include mbstrings.h.
4055 (scm_boot_guile_1): Don't init mbstrings module.
4056 * hash.c (scm_hasher): Don't handle mbstrings.
4057 * gscm.c (gscm_run_scm): Don't init mbstrings module.
4058 * gc.c (scm_gc_mark): Don't handle mbstrings.
4059 (scm_gc_sweep): Likewise.
4060 * eval.c (SCM_CEVAL): Don't handle mbstrings.
4061 * eq.c (scm_equal_p): Use SCM_TYP7S, not SCM_TYP7SD.
4062 * tags.h (SCM_TYP7SD): Removed.
4063 (SCM_TYP7D): Removed.
4064 (scm_tc7_mb_string): Removed.
4065 (scm_tc7_mb_substring): Removed.
4066 * print.c (scm_iprin1): Handle char printing directly. Don't
4068 Don't include "mbstrings.h".
4069 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
4070 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
4072 Don't include "mbstrings.h".
4073 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
4074 (SCM_SYMBOL_SLOTS): Define as 4.
4075 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
4076 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
4077 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
4078 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
4079 struct.c, threads.c, throw.c, unif.c, variable.c: Use new
4080 ("gen"-less) I/O function names.
4081 * ports.c (scm_add_to_port_table): Don't set port's
4083 * ports.h (scm_port_representation_type): Removed.
4084 (scm_string_representation_type): Removed.

4086 (SCM_PORT_REPRESENTATION): Removed.
4087 (SCM_SET_PORT_REPRESENTATION): Removed.
4088 * genio.h: Use new function names.
4089 * genio.c: Don't include "extchrs.h".
4090 (scm_gen_putc, scm_gen_puts, scm_gen_write, scm_get_getc):
4092 (scm_putc, scm_puts, scm_lfwrite): No longer static.
4093 (scm_getc): No longer static; handle line and column changes.

4095 (scm_do_read_line): Renamed from scm_gen_read_line.
4096 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
4097 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
4099 1997-10-12 Mark Galassi <rosalia@cygnus.com>
4101 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
4103 * gh_test_c.c (c_vector_test): some improvements on the vector
4106 * gh.h (gh_vector): this used to exist but do the wrong thing.
4107 Now it (almost) does the right thing, though it takes a list
4108 instead of the individual arguments. I need to see how it could
4110 (gh_list_to_vector): added this function as a macro. Corresponds
4111 to Scheme's (list->vector ...).
4112 (gh_vector_to_list): added this function as a macro. Corresponds
4113 to Scheme's (vector->list ...).
4115 * gh_data.c (gh_vector_ref): renamed from gh_vref to
4116 gh_vector_ref, so that it resembles the Scheme routines more.
4117 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
4118 resembles the Scheme routines more.
4119 (gh_make_vector): this used to be (stupidly) called gh_vector().
4120 This is the right name, since it does the same thing as the Scheme
4121 (make-vector ...) procedure.
4123 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4125 * ports.h: #include "libguile/print.h"
4127 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
4128 Some indentation fixes.
4130 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
4131 longer a user field; New field: class_flags.
4133 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
4135 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
4137 * gh_data.c (gh_bool2scm): new function which replaces
4138 gh_int2scmb(), which is now tagged as obsolete.
4140 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4142 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4143 macros should by convention not test for NIMPness.)
4144 (SCM_COERCE_OPORT): Adjust indentation.
4146 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4147 SCM_NIMP test before SCM_PRINT_STATE_P.
4149 * struct.c, struct.h, gc.c: Renamed:
4150 scm_struct_i_layout --> scm_vtable_index_layout
4151 scm_struct_i_vcell --> scm_vtable_index_vcell
4152 scm_struct_i_vtable --> scm_vtable_index_vtable
4153 scm_struct_i_printer --> scm_vtable_index_printer
4154 scm_struct_i_vtable_offset --> scm_vtable_offset_user
4156 * struct.c (scm_print_struct): Use new printer slot; Default
4157 printing: Also output hex code of vtable so that type identity
4158 will be indicated as well.
4159 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4160 Removed struct_printer_var; Removed struct-vtable-offset;
4161 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4162 vtable-offset-user): New constants.
4164 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
4165 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
4166 If this slot contains a procedure, use that to print structures of
4167 the type represented by this vtable.
4169 * print.c (scm_iprin1): Don't print arguments of macro
4170 transformers. (They are always: exp env.); Bugfix: Unmemoize
4171 transformer source with correct environment.
4173 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4175 Streamlining of call-with-dynamic-root:
4177 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
4178 there is now only one catch.
4179 (cwdr_outer_body): Removed.
4180 (cwdr_handler): New function.
4181 (scm_internal_cwdr): New function to perform the function of cwdr
4182 but take args that are more useful to C code. Also, the handler
4183 is now invoked *outside* of the new dynamic root, like the docs
4184 say. We no longer have to catch absolutely all errors, the caller
4185 is responsible for using a handler that does not throw, if he
4187 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4188 * root.h (scm_internal_cwdr): New prototype.
4190 Even more but risky streamlining:
4192 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4193 allocation of the jumpbuf of a root continuation. The changes
4194 below are controlled by it. They are now deactivated.
4195 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4196 the JMPBUF of the scm_rootcont to NULL before returning.
4198 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4199 when they are non-NULL.
4200 (scm_gc_mark): Likewise, mark only when non-NULL.
4202 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4203 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4205 * gc.c (scm_done_malloc): New function.
4206 gc.h (scm_done_malloc): New prototype.
4208 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
4209 (struct scm_print_state) [revealed]: New field.
4210 (scm_print_state_vtable): Make visible to the outside world for
4211 type checking purposes.
4212 (scm_valid_oport_value_p): New prototype.
4214 * print.c (scm_valid_oport_value_p): New function to check whether
4215 a certain value is acceptable as a port argument.
4216 (scm_print_state_vtable): New variable.
4217 (scm_free_print_state): Set `revealed' field to false.
4218 (scm_iprin1): Call user supplied closure printer with
4219 scm_printer_apply. Print in the traditional way when there isn't
4220 one or when it returns #f.
4221 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4222 Accept a port/print-state pair in addition to just a port.
4223 (scm_prin1): Don't return the print_state to the pool when it has
4225 (scm_printer_apply): Set `revealed' field of print_state to true.
4226 (scm_init_print): Set scm_print_state_vtable.
4227 (print_state_fluid, print_state_fluid_num): Removed.
4229 * throw.h (scm_handle_by_proc_catching_all): New prototype
4230 throw.c (scm_handle_by_proc_catching_all): New function
4232 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4234 * Makefile.in: Regenerated with automake 1.2c.
4236 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4238 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4239 was looping endlessly.
4241 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4243 * strports.c (scm_eval_string): Don't close the port.
4245 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4246 former returns a nice normal integer. (Thanks to Daniel
4249 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4251 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4252 makefile variable as a build parameter called LIBS. The
4253 build-guile program will use this, for the time being.
4254 * Makefile.in: Regenerated.
4256 Thanks to Shiro Kawai:
4257 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4258 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4261 * Makefile.in: Regenerated with automake 1.2a.
4263 * script.c (scm_compile_shell_switches): If we hit the -c or --
4264 arguments, don't set the car of (command-line) to scm_usage_name,
4265 the prettified name of the guile executable; give it the full
4266 path, the way shells usually handle $0.
4268 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4270 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4271 Scheme-level name `array-map' and renamed `serial-array-map' to
4272 `serial-array-map!'.
4274 * backtrace.c: Introduced exception handlers which now enclose
4275 `display-error' and `display-backtrace' so that error reporting
4276 won't get into infinite loops if an error occurs during displaying
4277 of the error. This can very easily happen with user supplied
4278 print call-back routines.
4280 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4282 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4283 the names `serial-array-map' and `array-map' should be removed.)
4285 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4287 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4288 Added #include "objects.h"
4290 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4291 Add #include "feature.h".
4293 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4294 (modinclude_HEADERS): Added objects.h.
4296 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4297 This test is needed at many places in the code and should be
4298 abstracted. (Motivated by the need of this test in libguiletk.)
4300 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4301 (scm_eval_string), load.c (scm_primitive_load,
4302 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4303 Use SCM_EOF_OBJECT_P.
4305 * eval.c (scm_init_eval): Add feature `delay'.
4307 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4309 * scmhob.h: Removed.
4311 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4313 * list.h (SCM_LISTn): New macros. Make list creation in C code
4314 prettier. The idea comes from STk.
4316 * sequences.h, sequences.c, append.h, append.c: Removed. These
4317 files implemented non-R4RS operations which would encourage
4318 non-portable programming style and less easy-to-read code.
4320 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4323 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4324 sequences.h, #include append.h.
4326 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4329 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4331 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4333 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4335 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4337 * eval.c: Added #include "objects.h"
4339 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4342 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4343 adjacent smob numbers.
4345 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4347 * procprop.h: Added declaration of scm_i_inner_name.
4349 * gsubr.c: New global symbol scm_i_inner_name.
4351 * debug.c (scm_procedure_name): Try procedure property
4352 `inner-name' if `name' fails.
4354 * print.c (scm_iprin1): Use scm_macro_name.
4356 * eval.c (scm_m_define): Give names to macros as well; Only the
4357 first top-level definition gives a procedure/macro a name.
4358 Otherwise confusing names can turn up in backtraces.
4359 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4360 `name'; Give names to macros as well.
4362 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4363 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4366 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4368 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4370 (prinmacro): Removed. The code has been moved/merged into print.c
4371 in order to decrease code redundancy. We want macros to print in
4372 a way equivalent to procedures, and it would be silly to duplicate
4373 the required code. (We don't want to maintain two places.)
4374 (macrosmob): Print field is now a NULL pointer.
4376 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4377 scm_macro_transformer): New prototypes.
4378 (scm_tc16_macro): Declared.
4380 * print.c (scm_iprin1): Added code for printing of macros. Macros
4381 are now printed in a way equivalent to procedures.
4383 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4385 * procs.h (scm_closure_p): Added declaration.
4387 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4389 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4390 Shouldn't pass "heap" as the subr name.
4392 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4394 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4395 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4396 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4397 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4398 SCM_BOOL_T. Any non-false value is true.
4400 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4402 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4403 scm_gensym): Added prototypes.
4405 * symbols.c (scm_gensym): New function. This will speed up
4406 certain types of applications (such as macro systems) which
4407 generate lots of symbols.
4409 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4411 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4413 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4415 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4416 specifier, since (2) or (2 . 3) would cause SEGV.
4417 (scm_transpose_array): more argument checking fixes.
4419 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4421 * Makefile.in: Regenerated.
4423 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4425 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4427 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4429 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4431 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4433 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4434 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4437 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4438 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4439 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4440 scm_array_p, scm_array_rank, scm_array_dimensions,
4441 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4442 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4443 scm_array_prototype): Added case scm_tc7_wvect.
4445 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4447 * errno.h: prototype for scm_strerror.
4448 * error.c (scm_strerror): new procedure.
4450 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4452 * list.c (scm_list_append_x): Allow non-pair as last argument.
4453 This is consistent with the R4RS append and is probably the
4454 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4456 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4458 * stime.h: prototype for scm_times.
4459 * stime.c (scm_times): new procedure.
4460 * ioext.c (scm_fseek): if the first argument is a file descriptor
4462 (scm_ftell): if the first argument is a file descriptor call lseek
4464 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
4465 * filesys.c (scm_chmod): if the first argument is a file descriptor,
4467 (scm_chown): if the first argument is a port or file descriptor,
4469 (scm_truncate_file): new procedure.
4470 Add DEFER/ALLOW INTS to a few other procedures.
4471 (scm_fsync): new procedure.
4472 (scm_open_fdes): new procedure.
4473 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
4475 (scm_fcntl): the first argument can now be a file descriptor. The
4476 third argument is now optional.
4478 * posix.c (scm_execl, scm_execlp): make the filename argument
4479 compulsory, since omitting it causes SEGV.
4480 (scm_sync): return unspecified instead of #f.
4481 (scm_execle): new procedure.
4482 (environ_list_to_c): new procedure.
4483 (scm_environ): use environ_list_to_c. disable interrupts.
4484 (scm_convert_exec_args): take pos and subr arguments and
4485 improve error checking.
4487 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4489 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4490 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4491 argument to SCM_ASSERT. Furthermore, the name of the function
4492 should be passed as first argument when signalling
4493 SCM_WNA. (Thanks to Thomas Morgan)
4495 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4496 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4497 dispatches on the number of actual args has a default case
4498 reporting an internal error. This is a vestige from a version
4499 that mallocated a SCM vector to hold the arguments. In the
4500 current version this check is too late: if it ever happens we will
4501 have already overstepped the bounds of the array.
4503 Also, the patch [...] adds a check for too many actual arguments."
4505 mdj: Removed check for "internal programming error".
4507 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4509 * gh_io.c (gh_write): New function.
4511 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
4512 throw.c (scm_internal_stack_catch): New sibling to the other catch

4656 but that should be much less likely.

4676 (scm_setpwent): For setpwent.
4677 (scm_setegid): For setegid.

4698 think this is left over from the (eq? '() #f) days.
4700 * read.c (recsexpr): Give this a dummy definition if
4701 DEBUG_EXTENSIONS isn't #defined.
4703 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

4730 have to do this explicitly. Also, if regexp/basic is supplied, then
4731 turn off REG_EXTENDED.
4732 (scm_init_regex_posix): New regexp/basic symbol.
4733 (REG_BASIC): #define this if it is not already present.

4770 (init_build_info): New function.

4776 * root.c: Establish a reliable catch-all handler for the new root.
4777 After all the Scheme handler function might signal an error too,
4778 and we don't want to lose that.
4779 (cwdr_inner_body): Renamed from cwdr_body.
4780 (cwdr_outer_body): New function, to establish the user's handler,
4781 and pass control to cwdr_inner_body.

4789 * throw.h (scm_handle_by_message_noexit): New prototype.
4791 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
4792 across this. Only works on GCC. Otherwise, we hope for the best.
4793 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4794 the feeling that real thread systems will not need this...
4796 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4798 Try to detect when people are using one version of libguile and a

4810 primitive definitions under their Scheme names.
4812 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4813 1:2. Helps avoid confusion between installed and uninstalled libs.
4815 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4818 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4819 backslash from definition; this should be used like: GDB_INTERFACE;
4821 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4823 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
4824 new port unbuffered until its stream has been set.
4826 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4828 * ports.h: new prototype.

4838 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4840 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA

4844 * tag.c (scm_tag): Remove unreachable statement.
4845 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4846 top of the word, it should be unsigned.
4848 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4849 is defined, to avoid warnings; it's only used in the
4850 conflict-checking code. Which might go away anyway.
4851 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4852 conditionals; put the label definition in an #if too, to stifle
4855 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4856 ChangeLog-threads in the distribution.
4857 * Makefile.in: Regenerated.

4867 * load.c (scm_init_load_path): Append $(datadir)/guile to
4868 %load-path, so modules do not have to be installed in Guile's
4869 current version directory.
4871 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4873 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4874 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.

4898 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4899 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4902 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4904 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4905 supplied. (Change from Tim Pierce.)
4907 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4909 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4910 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4911 default and not `()'. `#f' is the canonical non-value in Scheme,
4914 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4916 * struct.c (struct_printer): New variable that holds a handle on
4917 the Scheme variable *struct-printer*. This variable can be set by
4918 Scheme code to override the printing of structures.
4919 (scm_print_struct): If struct_printer is set, call it. If it is
4920 not set, or returns #f, print the structure in the old fashion.
4921 Include "eval.h" for scm_apply.
4923 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4925 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4926 scm_struct_i_n_words to get the number of fields, not
4927 -scm_struct_n_extra_words.
4929 On the route to fancier struct printing:
4930 * struct.c (scm_print_struct): New function to print a structure.
4931 Include "genio.h" to support it. This function doesn't do
4932 anything interesting right now, but I think it should be here
4934 * struct.h: Include "print.h" and add prototype for
4936 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4937 print structures ourself.
4939 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4941 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4942 before applying the handler in case it doesn't return.
4944 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>

4948 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4951 * posix.c (scm_uname): interpret only negative values as an error.
4952 Solaris normally returns a positive value.
4954 * script.c (scm_compile_shell_switches): if we are not going into
4955 an interactive repl, set scm_mask_ints to zero so that asyncs can
4958 * simpos.c (scm_system): don't ignore/unignore signals around
4961 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4964 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4965 done in boot-9.scm instead.
4967 * scmsigs.c, async.c: Major rewriting of signal handling code.
4968 (scm_sigaction): new procedure.
4969 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4971 (scm_raise): return unspecified, throw error on failure.
4973 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4975 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4976 feature, to help boot-9.scm decide whether to import the regex
4979 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4981 * eval.c: Include scmconfig.h at the beginning of the file so that
4982 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
4985 * regex-posix.c: #include "_scm.h" before conditionally #including
4986 <regex.h>; the former defines HAVE_REGCOMP.
4988 * regex-posix.c: #include <regex.h> conditionally, so the file is

4992 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4994 Add new R4RS-compliant syntax for keywords.
4995 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
4996 regardless of the setting of the `keywords' read option.
4997 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
4998 can be re-read no matter what the setting of the `keywords' read
5001 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5003 Add support for POSIX regular expressions.
5005 * regex-posix.c, regex-posix.h: New files. (Some code
5006 is taken liberally from rx/rgx.c in the old Guile dist.)
5008 * init.c: Include regex-posix.h.
5009 (scm_boot_guile_1): Call scm_init_regex_posix.
5011 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5012 Add regex-posix.[ch] sources.
5013 * Makefile.in: Regenerated.
5015 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5016 to do this automatically? It didn't for me, bleh.)
5018 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5020 * fports.c (print_pipe_port): New function.
5021 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5022 latter doesn't even take the right arguments.
5024 * Makefile.am: Increment shared lib revision number. I think
5025 sometimes the uninstalled Guile finds the installed shared lib;
5026 Gord says doing this might help. As things turned out, I can't
5027 say whether it does.
5028 * Makefile.in: Regenerated.
5030 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5031 passing it as the closure argument to scm_boot_guile. (Bill
5034 * ports.c (print_void_port, putc_void_port, puts_void_port,
5035 write_void_port, flush_void_port, getc_void_port, close_void_port,
5036 noop0): Use ANSI prototypes instead of K&R declarations, so the
5037 initialization of void_port_ptob gets aggressively type-checked.
5038 Fix arguments of print_void_port and write_void_port. (Bill

5072 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5074 * script.c (scm_find_executable): Use prototype-style definition
5075 here; apparently it's not quite right to have const in a prototype
5076 and then use a K&R declaration. I wonder if stuff like this will
5077 go away if we compile with -Wrequire-prototypes, or whatever that
5078 is... (Bernard URBAN)
5080 * scmhob.h: New text from Bernard URBAN.
5082 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5084 * script.c: Don't #define const on hpux. Configure takes care of
5085 this. (Thanks to Larry Schwimmer.)
5087 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5088 decide whether to #include <unistd.h>, instead of listing a bunch
5089 of systems. Don't #include stdio twice. Removed dyked-out
5090 definition of scm_find_impl_file.
5092 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5094 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5095 library version info to 1:0.
5096 * Makefile.in: Regenerated.
5098 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

5102 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5103 throw.c: Update copyright years; these files have been worked on
5104 significantly in 1997, but only had copyright years for 1996.
5105 Also, change name of copyright holder on some from Mikael
5106 Djurfeldt to Free Software Foundation; he has signed papers
5107 assigning the changes to the FSF.
5109 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5110 reason not to give the user the option.
5112 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5113 Return #f on end-of-file when scanning table (i.e. when called
5114 with no arguments). Try to catch errors, when we can.
5115 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5117 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5118 external declarations. These are useful.
5120 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5122 * posix.c: don't include <sys/select.h> or define macros for
5123 select, since they were not used in this file.
5125 * filesys.c (scm_select): make the fifth parameter microseconds,
5126 not milliseconds. let the fourth parameter be either a real value
5127 or an integer or #f. The first, second and third arguments can
5128 now be vectors: the type of the corresponding return set will be
5130 (set_element, get_element): new static procedures.
5132 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5134 * strports.c (scm_eval_string): New function.
5135 (scm_eval_0str): Trivially re-implemented in terms of
5137 * strports.h (scm_eval_string): New extern decl.
5139 * net_db.c (h_errno): Add extern decl for this.
5141 * fports.c (local_pclose): New function.
5142 (scm_pipob): Use it in the initializer here.
5145 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5146 Use a meaningful error message when signalling an error. For
5147 this, scm_gethost must check h_errno rather than errno.
5149 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5151 * Makefile.in: Regenerated, using automake-1.1p.
5153 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5155 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5156 not SCM_UNSPECIFIED.
5158 * script.c (scm_compile_shell_switches): don't append (quit) if
5160 (scm_shell): call scm_exit_status and exit on the result of the
5163 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5165 Ensure that shared substrings are handled properly when passed to
5166 a system call or other foreign function. Many thanks to Tim
5168 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5169 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5170 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5171 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

5173 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5174 (scm_display_error_message): use RO macros when strings may be RO.
5175 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5176 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5177 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

5181 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
5182 scm_strftime), vports.c (scm_make_soft_port): use
5183 SCM_COERCE_SUBSTR to make sure shared substrings are
5186 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5188 * error.c (scm_error): Add newline to error message.
5190 * init.c (scm_init_standard_ports): Doc fix.
5192 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5194 * dynl-shl.c: Completely replaced with new code from Bernard
5197 * script.c (scm_ice_9_already_loaded): New variable.
5198 (scm_compile_shell_switches): Use it.
5200 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5202 * filesys.c (scm_input_waiting_p): add missing third argument to
5205 * stime.c (scm_localtime): copy the result of localtime before
5206 calling gmtime in case they share a buffer.
5207 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5210 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5212 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5214 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5216 * Makefile.am (check-local): New target, which causes 'make check'
5217 to run gh_test_c and gh_test_repl, with some trivial input.
5218 * Makefile.in: Rgnrtd.
5220 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5222 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5225 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5227 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5228 sure how this was supposed to work.
5229 (scm_async_click): don't send SCM_TICK_SIGNAL.
5230 (scm_init_async): don't initialize %tick-thunk.
5232 * the following change doesn't affect the Scheme interface:
5233 gc-thunk is called at the end of garbage collection. however it's
5234 no longer implemented by pretending it's a signal.
5236 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5237 system async corresponding to scm_gc_thunk.
5238 * async.h: declare scm_gc_async.
5239 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5240 gc-thunk directly, instead of going through a signal handler.
5241 (scm_gc_async): new variable, points to the GC system-async.
5242 (scm_init_async): save the GC async as scm_gc_async instead
5243 of using system_signal_asyncs.
5244 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5246 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
5248 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
5249 Don't screw up if we're interrupted.
5250 * Makefile.in: Regeneradet.
5252 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5254 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5256 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5257 we're not using AM_INIT_GUILE_MODULE any more.
5258 * Makefile.in: Reneregated.
5260 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5262 Functions for finding variable bindings, grace à Tim Pierce.
5263 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5264 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5266 Get 'make dist' to work again.
5267 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5268 * Makefile.in: Regenerated, like a surry without a fringe on top.
5270 Changes for reduced Guile distribution: one configure script,
5272 * configure.in, configure: Removed.
5273 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5274 real configure script lives.
5275 * Makefile.in, scmconfig.h.in: Regenerated.
5277 * init.c: #include "script.h", to get prototype for script.c's
5280 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5282 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5283 scm_must_malloc, not raw malloc.
5285 * script.c (scm_compile_shell_switches): Dyke out debugging output
5288 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5290 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5292 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5293 system has them. Hope this is safe. Previously
5294 sys/timeb.h was included if HAVE_FTIME was defined or if
5295 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5296 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5298 * ioext.c (scm_setfileno): add missing third argument to
5299 scm_misc_error call.
5301 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5303 * eq.c (scm_equal_p): Correctly compare strings of different
5304 varieties. (Thanks to Tim Pierce.)
5306 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5308 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5309 #! block comment must occur on a line all by itself.
5311 Move most of the guts of shell command processing into libguile,
5312 so guile.c can be very small (and eventuallly auto-generated. (I
5313 mean, generated mechanically, not self-generated. Hmm.))
5314 * guile.c, script.c, script.h: New source files.
5315 * init.c (scm_boot_guile_1): Call scm_init_script.
5316 * libguile.h: #include "script.h".
5317 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5318 targets, for new executable.
5319 (libguile_la_SOURCES): Mention script.c.
5320 (modinclude_HEADERS): Add script.h.
5321 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5322 not dynamic linking is enabled. This is because we're generating
5323 executables now. Move CY_AC_WITH_THREADS call after those, so the
5324 values of cy_cv_threads_libs captures the libs chosen above.
5325 * Makefile.in, configure, aclocal.m4: Regenerated.
5327 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5328 We don't maintain this interface any more, and it just confuses
5331 * alloca.c: #include <scmconfig.h>, not <config.h>.
5332 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5333 it'll get included in disties.
5335 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5337 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5338 be distributed, because they confuse people.
5339 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5341 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5343 * configure.in: check for presence of gethostent (not present on
5344 OpenBSD by default).
5345 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5346 * configure, scmconfig.h.in: Regenerated.
5348 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5350 * backtrace.c (scm_backtrace): Split message string across
5351 newlines properly. GCC is more tolerant of this than other
5354 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5356 Merge threads directory into libguile.
5357 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5358 threads.h: New source files.
5359 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
5360 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5362 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5363 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5364 coop-threads.c.cygnus, coop-threads.h.cygnus.
5365 * configure.in: If we're using threads, include threads.o in
5367 * _scm.h, libguile.h: threads.h lives in this directory now.
5368 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5369 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5370 currently used, but brought along for information's sake.
5371 * ChangeLog-threads: log from old 'threads' directory.
5372 * Makefile.in, configure: Rebuilt.
5374 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5376 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5379 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5381 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5383 Merge GH interface library into libguile.
5384 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5385 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5386 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5387 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5389 (EXTRA_libguile_la_SOURCES): ... here.
5390 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5391 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5392 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5393 New variables, describing how to build the gh test programs.
5394 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5395 build the test programs, and we probably should have been linking
5396 libguile.la against them all along, to support AIX shared libs.
5397 Add cflags for threads to CFLAGS; add libs for threads to new
5398 variable THREAD_LIBS, used in Makefile.am.
5399 * ChangeLog-gh: log from old `gh' subdirectory.
5400 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5402 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5404 * acconfig.h: Undo change of Apr 9; including the definition of
5405 PACKAGE in the guile headers conflicts with applications' own
5407 * scmconfig.h.in: Regenerated.
5409 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
5411 * filesys.c (scm_fcntl): New function from Roland McGrath.
5412 (scm_init_filesys): New symbols for use with fcntl.
5413 * filesys.h: Added prototype.
5415 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
5416 when PROC is receiving no arguments.
5418 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5420 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5421 have S_IFSOCK. This is the case under Ultrix.
5423 * posix.c (scm_status_exit_val, scm_status_exit_val,
5424 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5425 Ultrix versions of WIFSTOPPED, etc., which assume that their
5426 arguments are lvalues (hmm).
5428 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5430 * eval.c: Doc fixes.
5432 * throw.c: Doc fixes; rearranged.
5434 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5436 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5438 * acconfig.h: Added entry for PACKAGE.
5439 * scmconfig.h.in: Regenerated.
5441 Changes to work with automake-1.1n, which has better libtool support.
5442 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5443 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5445 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5447 * Makefile.in: Rebuild.
5449 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5451 * stime.c (scm_mktime): take an optional zone argument.
5452 (scm_localtime): check putenv return value.
5453 (scm_strftime, scm_strptime): moved from posix.c. move #include
5455 stime.h, posix.h: update prototypes.
5456 (bdtime2c, setzone, restorezone): new static procedures.
5457 (scm_mktime, scm_strftime): use them.
5458 (scm_strftime): don't call mktime before strftime. Use
5459 filltime for return value.
5460 (filltime): convert NULL zname to #f.
5461 (scm_strptime): return a count of characters consumed, not
5462 the remaining string.
5464 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5466 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
5467 (scm_mktime): likewise.
5469 Uncomment localtime and mktime.
5471 * configure.in: add AC_STRUCT_TIMEZONE.
5473 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5475 * stime.c (scm_init_stime): don't define ticks/sec.
5476 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5477 return value problem and is still portable.)
5479 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5481 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5482 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5483 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5484 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5485 cpp_err_symbols.c): Corresponding changes.
5486 * Makefile.in: Regenerated.
5488 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5490 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5491 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5492 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5493 * putenv.c: new file, from sh-utils 1.12.
5495 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5496 since allocation isn't for Scheme objects.
5497 (scm_putenv): copy strings before placing in the environment.
5499 * stime.c (scm_current_time): throw an error if time returns -1,
5500 instead of returning #f.
5501 (scm_get_internal_real_time, scm_get_internal_real_time): use
5502 scm_long2num for return value instead of SCM_MAKINUM.
5504 * stime.h: prototypes updated.
5506 * stime.c (scm_time_in_msec): apparently unused, deleted.
5508 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5510 * configure.in: check for gettimeofday.
5512 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5513 which may be more usefully portable than a gettimeofday interface.
5515 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5517 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5519 * Makefile.in: Regenerated.
5521 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5523 * stime.c (filltime): recovered static procedure.
5524 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5527 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5528 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5530 * posix.c (scm_mknod): split the mode argument into type and perms
5531 arguments, like the extra fields returned by stat.
5533 * fports.c (scm_pipob): set the close, free and print procedures.
5534 (scm_close_pipe): new procedure.
5536 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5537 define them in boot-9.scm
5539 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5541 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5542 wan't defined. Don't include fd.h.
5544 * Previously fd.h was regenerated whenever configure was run,
5545 forcing a couple of files to be recompiled.
5547 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5548 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5549 Check for _fileno as well as _file.
5551 * ioext.c: don't fd.h.
5552 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5555 * Change the stratigy for getting information about errno
5556 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5557 generating lists of symbols during the build process, which will
5558 not always work, include comprehensive lists in the distribution.
5559 To help keep the lists up to date, the "check_signals" and
5560 "check_errnos" make targets can be used.
5562 * configure.in: don't check for a command to extract errno codes.
5563 * Makefile.am: update file lists, remove errnos.list and errnos.c
5564 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5565 check_errnos targets.
5566 (CLEANFILES): remove errnos.c and errnos.list, add
5567 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5568 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5569 * errnos.default: deleted.

5571 * cpp_errno.c: renamed from errnos_get.c.
5572 * cpp_err_symbols, cpp_sig_symbols: new files.
5573 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5574 * error.c (scm_init_error): #include cpp_err_symbols instead of
5576 * posix.c (scm_init_posix): don't intern signal symbols. #include
5579 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5581 * strop.c (scm_i_index): allow the lower bound to be equal to the
5582 length of the string, so a null string doesn't always give an error.
5584 * posix.h: new prototypes.
5585 * posix.c (scm_status_exit_val, scm_status_term_sig,
5586 scm_status_stop_sig): new functions, as in scsh. They break down
5587 process status values as returned by waitpid.
5589 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5591 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5592 configure doesn't know about it.
5594 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5596 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5598 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5599 which defines C variables with global linkage.
5601 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5603 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5606 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5608 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5609 has time to check why this doesn't work well with continuations.
5611 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5613 * Fix shell syntax error; some shells won't tolerate
5614 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5616 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5618 * posix.c (scm_uname): throw an error if uname fails instead
5621 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5623 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5626 * async.c (scm_ints_disabled): definition moved from error.c.
5628 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5630 * acconfig.h: Removed PACKAGE.
5632 * scmconfig.h.in: Regenerated.
5634 * snarf.h: g++ says it's non-portable not to specify the first
5635 argument in a varargs declaration. I introduced the first
5636 argument by using preprocessor conditionals.
5638 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5640 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5641 (scm_freopen): use RO string macros for filename and modes.
5642 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5644 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5645 (scm_mknod): use RO string macros for path.
5647 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5648 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5650 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5651 use SCM_ROSTRINGP and SCM_ROCHARS.
5653 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5655 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5658 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5659 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5660 support for byte vectors.
5662 * print.c (scm_iprin1): Limit number of vector elements printed
5663 according to pstate->length.
5665 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5667 * backtrace.c (scm_display_error_message): don't segv if message
5670 * error.h: prototype for scm_error_scm.
5672 * error.c (scm_error_scm): new procedure, reimplements scm-error
5673 in C and uses scm_error.
5675 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5677 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5678 pointer to the Scheme variable read-hash-procedures and intern it
5679 in scm_init_read. Modify scm_read_hash_extend and
5680 scm_get_hash_procedure to use the pointer.
5682 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5684 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5685 (SCM_KEYWORD_STYLE): defined.
5687 * read.c (scm_read_opts): add a keywords option. This isn't a
5688 boolean option, in case someone wants to add support for DSSSL
5690 Setup scm_keyword_prefix symbol.
5691 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5693 I've left keyword support disabled by default, since it doesn't
5694 seem to break the module system and it gives R4RS standard behaviour.
5695 It can be reactivated with (read-set! keywords 'prefix).
5697 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5699 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5700 before constructing arbiter.
5702 * eval.c (scm_m_define): Bugfix: Check that the object is a
5703 closure before setting the procedure property!
5705 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5707 * ports.c: Removed `ungetc-char-ready?'.
5709 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5711 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5712 (idea from Mikael: make it a pair so scm_permanent object only
5714 (scm_read_hash_extend): don't call scm_permanent_object.
5715 (ideas from Mikael): if chr is already in the list, replace its
5716 procedure instead of appending it again. If proc is #f, remove
5718 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5720 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5722 * gdbint.c (gdb_read): update scm_lreadr usage.
5724 * load.h: update prototypes.
5726 * load.c (scm_primitive_load, scm_read_and_eval_x,
5727 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5729 * read.h: add prototype for scm_read_hash_extend. Change args for
5732 * read.c (scm_read_hash_procedures): new variable.
5733 (scm_read_hash_extend): new procedure.
5734 (scm_get_hash_procedure): new procedure.
5735 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5736 for extended # processing.
5737 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5738 scm_read_token): remove case_i, sharp arguments. Change callers.
5740 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5742 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5743 (SCM_CASE_INSENSITIVE_P): define.
5745 * read.c: add case-insensitive option to scm_read_opts.
5746 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5747 to determine whether to convert symbol case.
5748 (default_case_i): definition removed.
5749 * read.c (scm_read_token): if case_i, downcase ic before doing
5752 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5754 * configure.in: Added configuration option `guile-debug'.
5755 Configure with --enable-guile-debug if you want a bunch of extra
5756 functions used for debugging when developing Guile.
5758 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5760 * procs.c (make-cclo): New undocumented debugging procedure: Make
5761 compiled closure with internal procedure PROC and length LENGTH.
5762 Only compiled if GUILE_DEBUG is defined.
5764 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5766 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5768 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5770 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5771 with 3 or more args internally to the evaluator.
5773 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5775 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5776 with 3 or more args internally to the evaluator. This is mainly
5777 because we don't want to pass entry and exit points of the
5778 debug support twice, but it also seems to increase the speed of
5779 the evaluator for such calls (e. g. (+ 1 2 3)).
5781 * backtrace.c (scm_display_application): New procedure:
5782 display-application; Set fancy printing parameters individually
5783 for different types of display (backtrace, error, application).
5784 (These should of course be customizable!)
5786 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5787 clear the CHECK-flags.
5789 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5791 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5793 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5795 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5796 from pairs with a GLOC in the car.
5798 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5799 otherwise `symbol-hash' will behave badly.
5800 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5801 we get segmentation fault!
5803 * symbols.c: Added #include "weaks.h". New functions:
5804 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5805 moved to an extraneous library when we split libguile.)
5807 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5809 * filesys.c (scm_stat): stat now takes fport arguments too as
5810 documented in the manual.
5812 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5814 * debug.c (scm_single_step): Bugfix: Call continuation with
5815 scm_call_continuation instead of throwing to it.
5817 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5819 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5820 argument wasn't declared to be optional.
5822 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5824 * stime.c (scm_init_stime): Add feature "current-time".
5826 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5828 * throw.h: prototype for scm_exit_status.
5829 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5830 args to derive an exit status. Allows (quit) to work from a
5832 (scm_exit_status): new function.
5835 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5837 * eval.c (scm_deval): Removed some old code.
5838 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5840 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5843 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5846 * procs.c: Introduce the existent C function scm_thunk_p at the
5847 Scheme level as well.
5849 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5851 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5852 used from C to easily lookup the value of a symbol in the current
5855 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5857 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5858 scm_init_unif in this file. This will also fix a previous problem
5861 * configure.in: Added AM_MAINTAINER_MODE
5863 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5865 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5868 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5870 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5871 source files that are not always included in libguile but should
5872 have their dependencies calculated by automake. This variable is
5873 recognized by automake, no further magic is needed.
5874 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5875 to deal exclusively with *.lo files, as it seems. The *.o files
5876 are built automatically when the corresponding *.lo file gets
5879 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5881 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5884 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5886 * unif.c (scm_array_set_x): minor change to argument error checking.
5888 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5890 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5891 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5892 They should only be included in the library at configure.in's
5894 (libguile_la_LDADD): Include the appropriate .lo files here.
5895 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5896 so we know when to build them (and their .lo bretheren).
5897 * configure.in (LIBLOBJS): New substituted variable. We let
5898 configure decide which .o files to include in LIBOBJS, and then
5899 put the corresponding list of .lo files in LIBLOBJS. The latter
5900 is what we pass to libtool.
5901 * Makefile.in, configure: regenerated.
5903 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5905 * symbols.c (scm_sysintern0): New function. Contains the core of
5906 old scm_sysintern but doesn't take a second value argument.
5907 (scm_sysintern): Now uses scm_sysintern0.
5908 (scm_sysintern_no_module_lookup): Renamed to
5909 scm_sysintern0_no_module_lookup and doesn't take a second value
5910 argument any longer.
5912 * symbols.h (scm_sysintern0: Added declaration.
5914 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5915 scm_sysintern when interning option keys. Otherwise we risk
5916 destroying the values of already interned variables.
5918 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5919 scheme-level boolean (use SCM_NFALSEP).
5921 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5923 (scm_backtrace): New function. (C version of old function from
5924 boot-9.scm) Motivation: Make it possible to display backtraces
5925 without depending on boot-9.scm. (I'm uncertain if this
5926 motivation is good enough...)
5928 * root.h (scm_root_state): Add member the_last_stack_var.
5929 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5931 * root.c (mark_root): Mark scm_the_last_stack_var.
5933 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5936 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5938 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5939 1. mark_lazy_catch didn't mark the smob.
5940 2. Both functions above have standard variants:
5941 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5942 free_lazy_catch --> scm_free0.
5944 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5946 * throw.c (scm_internal_lazy_catch): New function.
5947 (scm_lazy_catch): Rewritten to use it.
5948 (scm_ithrow): Handle the new lazy catch representation.
5949 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5950 that doesn't have a jmpbuf is a lazy catch clause.
5951 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5952 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5953 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5955 (scm_init_throw): Register the new lazy-catch smob type.
5956 * throw.h (scm_internal_lazy_catch): decl for new function.
5958 * throw.c (scm_internal_catch): Doc fixes.
5960 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5961 configure.in. Including this might cause problems if applications
5962 that link against libguile include their own copies of alloca, but
5963 if they're using autoconf, they should be adding libguile to LIBS
5964 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5965 the copy in libguile, and things will be okay. (I think.)
5967 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5969 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5971 strop.h: move prototypes too.
5973 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5975 * posix.c (scm_init_posix): don't intern EINTR since it's now done
5978 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
5979 etc. I deleted them from filesys.c long ago, but didn't
5980 notice they were here too (although ineffective since
5981 sys/stat.h wasn't included).
5983 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
5985 * eval.c: Don't define alloca in GCC case. gcc will automatically
5986 use __builtin_alloca if appropriate.
5988 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5990 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
5991 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
5992 that values of automatic variables are preserved. See comments
5993 for safe_setjmp for details.
5995 Change from Thomas Morgan:
5996 * variable.c: Include eq.h.
5997 (var_equal): New function.
5998 (variable_smob): Use var_equal as the discriminator for variables.
6000 * throw.c (s_throw): Remove extraneous declaration.
6002 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6003 * eval.c: Add necessary CPP cruft to support that.
6004 * configure, Makefile.in, scmconfig.h.in: regenerated.
6006 Change from Thomas Morgan:
6007 * procprop.c (scm_procedure_properties): Convert the Scheme
6008 boolean returned by scm_procedure_p into a C boolean before using
6009 it as a condition for SCM_ASSERT.
6010 (scm_procedure_property): Likewise.
6012 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6013 indications of Unixness.
6016 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6018 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6020 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6022 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6023 "unknown # object" error messages.
6025 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6026 (scm_i_index) and declare it static. Add a 'direction' argument
6027 to indicate what way the search should go.
6028 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6030 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6031 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6033 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6035 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6037 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6038 to avoid clash with various scsh forks.
6040 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6042 The following two changes (ramap.c, throw.c) are motivated by the
6043 apparent unportability of forward declarations of static arrays of
6044 the form `static foo bar[];'.
6046 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6047 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6049 * throw.c (scm_throw): Moved above scm_ithrow.
6051 * options.h: Removed the extern declarations of scm_yes_sym and
6052 scm_no_sym since these are static.
6054 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6056 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6058 * Makefile.am: remove AWK=@AWK@.
6059 Add a rule for generating errnos.list.
6060 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6062 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6063 don't extract errnos, just set a variable (avoids the
6064 need to recompile error.c just because configure is run.)
6066 * unif.h: update prototypes.
6067 * unif.c (scm_uniform_array_read,write): change the offset and
6068 length arguments to start and end, for consistency.
6070 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6072 * ioext.h: update prototypes.
6073 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6074 scm_read_line_x, it's a more general procedure using an
6075 interface from scsh. read-line and read-line! are now defined
6077 Note that the new read-line trims the terminator
6078 by default, previously it was appended to the returned string. An
6079 optional argument specifies how to process the terminator (scsh
6080 compatible). For the old behaviour: (read-line port 'concat).
6081 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6082 returns a pair, but is converted to multiple values if the scsh
6085 socket.h: update prototypes.
6086 * socket.c (scm_recvfrom): for consistency with other procedures,
6087 take start and end as separate optional arguments.
6088 (scm_recv, scm_recvfrom): don't allow the second argument
6089 to be a size, only a buffer. Change the scheme names to
6090 recv! and recvfrom!. Don't return the buffer.
6092 * ioext.h, posix.h: move prototypes too.
6093 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6094 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6095 "read.h" and "unif.h".
6096 * ioext.c: include "chars.h"
6098 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6100 * dynl.c: The dynamic linking and module registration functions
6101 are now defined even when dynamic linking is not available for the
6102 host system. Some of their functionality can be done without
6103 dynamic linking; when it's really needed, they throw errors.
6105 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6107 * configure.in: Only define DYNAMIC_LINKING when one of the system
6108 dependent functions is detected.
6109 * dynl.c (scm_dynamic_func): New function to get the address of a
6110 function in a dynamic object.
6111 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6112 produced by scm_dynamic_func as the thing to call.
6114 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6116 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6117 (scm_register_module_xxx, scm_registered_modules,
6118 scm_clear_registered_modules): New functions.
6120 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6122 * symbols.c (scm_sysintern): Renamed to
6123 scm_sysintern_no_module_lookup.
6124 (scm_sysintern): New function to take the place of the old
6125 scm_sysintern. It uses the current toplevel lookup closure to give
6126 the symbol its value. This is a temporary hack to put packages
6127 like gtcltk into their own module.
6128 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6129 us whether `scm_top_level_lookup_closure_var' has been initialized
6131 * eval.c (scm_init_eval): Set it.
6133 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6135 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6136 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6138 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6140 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6141 scm_sys_dup): deleted: FD capability will be added to other
6143 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6144 scm_fd_free, fd_smob, scm_intern_fd.
6145 (scm_open): renamed from scm_sys_open. Return a port instead of
6146 an FD object. Make the mode argument optional.
6147 (scm_sys_create): deleted, it's just a special case of open.
6148 (scm_init_filesys): move interning of constants O_CREAT etc.,
6149 here (were previously using SCM_CONST_LONG macro).
6150 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6152 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6153 include "fports.h" and <stdio.h>
6154 (scm_stat, scm_select): don't support FD objects.
6156 * error.h: adjust scm_syserror_msg prototype.
6157 * error.c (scm_syserror_msg): take an extra argument for errno.
6158 Using the global value didn't always work, since it could be
6159 reset by procedure calls in the message or args arguments.
6161 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6162 I don't understand why the check was there (and what about the
6165 * strop.c (scm_string_copy): allow shared substrings to be copied.
6167 * unif.h: corresponding change to prototypes.
6168 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6169 recognize two new optional arguments: offset and length. Allow
6170 the port argument to be an integer (file descriptor, for scsh).
6171 Include <unistd.h> for "read" prototype.
6173 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6175 * socket.c: don't include filesys.h.
6177 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6179 * Makefile.am: add AWK=@AWK@ (?)
6181 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6183 Add a rule to generate errnos.c from errnos.
6184 * error.c (scm_init_error): include errnos.c.
6185 * errnos_cnvt.awk: new file, converts the list of errno codes to
6187 * errnos_get.c: new file.
6188 * errnos.default: new file, contains errnos to try if they can't
6189 be extracted from errno.h.
6190 * configure.in: if using GCC, try and extract errno codes from
6194 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6196 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6197 * Makefile.am: Made libguile into a libtool library.
6198 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6199 Set libtool_libs to indicate that libguile is a libtool library.
6200 See guile/ChangeLog for details.
6201 * .cvsignore: ignore "*.lo", the libtool library objects.
6203 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6205 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6206 use htons in getservbyport argument.
6208 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6210 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6211 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6214 * objprop.c (scm_object_property): No need to take the CDR of the
6215 value returned by scm_object_properties, since Aug 20 change.
6217 * configure.in: When checking for struct linger, #include
6218 <sys/types.h> as well as <sys/socket.h>. I've never known
6219 <sys/types.h> to cause any portability problems, and Solaris's
6220 <sys/socket.h> needs it.
6221 * configure: Rebuilt.
6223 I think the Sun compiler has chosen a perverse way to interpret
6224 ANSI declarations combined with K&R definitions. We'll
6225 appease it a little bit. But when it invades France, we fight.
6226 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6227 * print.h (scm_iprlist): Here too.
6228 * numbers.c (scm_divbigdig): Change definition to match
6229 declaration in numbers.h.
6230 * unif.c (scm_makflo): Change definition to match declaration in
6233 * init.c (scm_boot_guile): Don't return the value of
6234 scm_boot_guile_1. This function doesn't return a value;
6235 scm_boot_guile_1 doesn't return a value (or return at all).
6237 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6240 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6241 compile. I have a feeling this function is a bad idea anyway ---
6242 one should always test for features, not systems.
6244 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6245 semicolons. Only pure luck kept this from being noticed earlier.
6247 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6249 * socket.c (scm_recvfrom): Added missing semicolon.
6251 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6253 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6254 the buffer and start and end positions for scsh networking
6257 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6259 * configure.in: Revert previous change to this file; the problem
6260 is due to transient automake weirdness.
6261 * configure: Rebuilt.
6263 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6264 PLUGIN/guile.libs. configure generates the latter from the former.
6265 * Makefile.in: Rebuilt.
6267 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6268 need this if we install scripts, like guile-snarf.
6269 * configure: Rebuilt.
6271 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6273 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6275 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6277 * socket.c (scm_addr_vector): fix faulty scm_listify.
6279 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6281 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6282 style block comment is no longer considered an error.
6284 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6286 * PLUGIN/guile.libs.in: New file.
6287 * PLUGIN/guile.libs: Removed from repository.
6288 * configure.in: Create PLUGIN/guile.libs from
6289 PLUGIN/guile.libs.in. This is for including additonal libraries
6290 needed for dynamic linking.
6291 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6292 instead of PLUGIN/guile.libs.
6294 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6296 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6298 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6299 occurrences of the given element from the list, not just the
6300 first. This is how the Emacs Lisp functions behave, how the
6301 analogous Common Lisp functions behave, and (I believe) how the
6302 older Maclisp functions worked. I realize that this change may
6303 break code, but it seemed better to break it before the Guile
6306 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6307 Their prototypes were already present in gc.h, but they weren't
6309 (scm_init_storage): Initialize scm_protects.
6310 * root.c (scm_protects): New element of scm_sys_protects.
6312 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6314 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6316 * libguile.h: Added #include "libguile/net_db.h".
6318 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6319 30 change. That file is only meant for communication between the
6320 configuration process and load.c. If code linked against libguile
6321 wants to get at the paths mentioned in libpath.h, it can call
6322 functions declared in load.h.
6324 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6326 * libguile.h: Removed #include "libguile/fdsocket.h"
6328 * net_db.c: Added #include <sys/socket.h>.
6330 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6332 * filesys.c (scm_input_waiting_p): use select in preference to
6333 FIONREAD, since the latter doesn't detect EOF.
6334 Throw error if neither select nor FIONREAD available.
6336 * socket.c (scm_connect): take a port, not a fd object.
6337 (scm_fill_sockaddr): throw an error if fam is not recognised.
6338 (scm_bind): use scm_fill_sockaddr.
6339 (scm_listen): take a port, not a fd object.
6340 (scm_accept): take and return a port. return #f in the car if
6341 address can't be got
6342 (scm_sock_fd_to_port): new procedure.
6343 (scm_socket): use scm_sock_fd_to_port.
6344 (scm_addr_vector): throw error if unrecognised address type.
6345 take an extra argument with the calling procedure name.
6346 (scm_getsockname): take a port. return #f if address can't be got.
6347 (scm_getpeername): take a port. return #f if address can't be got.
6348 (scm_recvfrom): take a port. return #f for address component if can't
6350 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6351 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6353 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6355 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6356 use separate data pointers, to allow them to be designed
6357 independently and reused.
6358 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6359 Renamed from catch_body, catch_handler, and uncaught_throw; made
6361 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6363 (scm_catch): Use the above.
6364 (scm_throw): Don't bother printing a message for an uncaught
6365 throw; we establish a default handler in init.
6366 * throw.h (scm_internal_catch): Prototype updated.
6367 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6369 (struct scm_body_thunk_data): New structure, used as data
6370 argument to scm_body_thunk.
6371 * init.c (struct main_func_closure): New structure, packaging up
6372 the data to pass to the user's main function.
6373 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6374 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6375 scm_internal_catch to establish a catch-all handler, using
6376 scm_handle_by_message. This replaces the special-case code in
6378 (invoke_main_func): Body function for scm_internal_catch; invoke
6379 the user's main function, using the main_func_closure pointer to
6380 decide what to pass it.
6381 * root.c (struct cwdr_body_data): Remove handler_proc member.
6382 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6383 (cwdr_handler): Removed.
6385 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6387 * socket.h (SCM_P): update bind prototype.
6388 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6389 include "feature.h".
6390 (scm_socket): return a port, not a file descriptor object.
6391 include "fports.h" and <unistd.h>
6392 (scm_bind): take a port, not a file descriptor object.
6393 take an extra argument for address args.
6395 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6396 INADDR_NONE, INADDR_LOOPBACK.
6398 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6400 * init.c: include net_db.h and not fdsocket.h.
6401 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6403 * Makefile.am: corresponding changes.
6404 * socket.h: renamed from fdsocket.h, fix names.
6405 * net_db.h: renamed from socket.h, fix names.
6406 * socket.c: renamed from fdsocket.c.
6407 remove _sys from procedure names.
6408 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6409 add "socket" to features list.
6410 * net_db.c: renamed from socket.c.
6411 remove _sys from procedure names.
6412 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6413 add "net-db" to features list.
6414 include "net_db.h". don't include <sys/socket.h> or
6417 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6419 * tags.h (scm_tags): Removed comma at end of last enumerator.
6421 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6423 Don't use GCC extensions to allocate space for debugging frames.
6424 (Here he goes again! Why do we put up with this?!)
6425 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6426 an scm_debug_info structure, not an in-line array of them. Add
6427 'info' member, to say how many vect elements we've used, for eval
6429 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6430 a new variable debug_info_end to mark the end of vect, instead of
6431 the address of the 'info' pointer itself.
6432 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6433 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6434 (SCM_APPLY): Explicitly allocate space for debug.vect.
6435 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6436 * stacks.c: Adjusted for new debug frame structure.
6437 (RELOC_INFO, RELOC_FRAME): New macros.
6438 (stack_depth, read_frames): Use them, and new scm_debug_frame
6439 element 'info', instead of magically knowing that eval frames have
6440 an info pointer sitting after vect.
6441 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6443 (scm_init_stacks): Formatting tweaks.
6445 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6447 Give GCC more control flow information, so it can be sure that
6448 variables aren't used uninitialized.
6449 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6450 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6451 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6452 scm_misc_error): Tell GCC that these functions never return.
6453 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6454 out the field type, call abort if SCM_ASSERT returns, to placate
6456 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6457 scm_wta ever returns. We can't handle this case anyway, and this
6458 gives the optimizer more information.
6459 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6460 scm_wta ever returns.
6462 In some cases, the code is fine, but GCC isn't smart enough to
6463 figure that out; this usually happens when one variable is only
6464 initialized and used when a particular condition holds true, and
6465 we know that condition will never change within a given invocation
6466 of the function. In this case, we simply initialize the variables
6467 to placate the compiler, hopefully to a value which will cause a
6468 crash if it is ever actually used.
6469 * print.c (scm_iprin1): Initialize mw_pos.
6470 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6471 * throw.c (scm_ithrow): Initialize dynpair.
6472 * unif.c (scm_uniform_vector_ref): Initialize cra.
6473 * struct.c (init_struct): Initialize prot.
6474 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6476 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6477 if EXPR contains no expressions.
6479 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6481 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6482 cause an infinite loop (???). So much for the algebraic
6483 equivalency of variable-sized arrays and alloca...
6485 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6487 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6488 a SCM boolean, not a C boolean.
6490 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6492 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6493 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6494 rules for raising scm_mtrigger. Previously, unfortunate but not
6495 unlikely circumstances could result in almost constant invokation
6496 of the gc. Now, this situations should be less likely, but they
6497 are not prevented completely.
6499 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6501 * numbers.c (scm_fuck): Procedure removed; looks like old test
6503 * numbers.h: Prototype removed.
6505 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6507 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6508 array to a pointer, to match my Nov 21 change in eval.c.
6510 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6512 * libguile.h: Added #include "libguile/backtrace.h", #include
6513 "libguile/stacks.h".
6515 * strings.c (scm_string scm_make_string scm_string_ref
6516 scm_string_set_x scm_string_equal_p scm_string_append):
6517 Bugfix according to scm patch from Aubrey Jaffer:
6518 Corrected long-standing
6519 (not (eqv? (integer->char 128)
6520 (string-ref (make-string 1 (integer->char 128)) 0)))
6521 bug found by John Kozak <jk@noontide.demon.co.uk>.
6523 * strports.c, strports.h: Make scm_eval_0str return the value of
6524 the last expression evaluated (previously, it returned void).
6526 * strports.c, strports.h: New function: scm_read_0str. Does what
6529 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6531 * simpos.c (scm_getenv): return #f if string can't be found in the
6532 environment instead of throwing an exception, for compatibility
6533 with numerous other systems.
6535 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6537 * Makefile.am (.c.x): Use guile-snarf.
6538 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6540 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6542 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6544 * backtrace.c (scm_display_error_message): Made non-static, and
6545 renamed from display_error_message.
6546 * backtrace.h (scm_display_error_message): Added extern decl.
6547 * throw.c (uncaught_throw): Use it to display the error message.
6549 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6551 * inet_aton.c: Use #if 0, not #ifdef 0.
6553 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6555 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6556 to convert the returned value.
6557 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6558 the offset argument.
6560 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6562 Add new interface to catch/throw, usable from C as well as
6564 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6565 (scm_internal_catch): New function, replaces...
6566 (scm_catch_apply): Deleted.
6567 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6568 mechanism which is a bit more code, but can be used nicely from C
6569 and implement the Scheme semantics as well.
6570 (scm_internal_catch): This is the replacement; it's named after
6571 the analogous function in Emacs.
6572 (scm_catch): Reimplemented in terms of the above.
6573 (struct catch_body_data, catch_body, catch_handler): New
6574 functions, used by scm_catch.
6575 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6576 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6577 support for new cwdr.
6579 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6582 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6584 * acconfig.h: Added DYNAMIC_LINKING symbol.
6585 * configure.in: Add option and checks for dynamic linking.
6586 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6587 dynl.h: New files for dynamic linking support.
6588 * Makefile.am (libguile_a_SOURCES):
6590 (modinclude_HEADERS): Added "dynl.h".
6591 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6593 * init.c (scm_boot_guile_1): Call
6594 scm_init_dynamic_linking to initialize dynamic linking support.
6596 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6598 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6599 (as we Schemers say). It needs to be global, so that I can tweak
6600 it for the proper operation of unexec.
6601 (scm_boot_guile_1_live): New variable, see above.
6603 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6605 * guile-snarf.sh: Removed.
6606 * PLUGIN/guile.libs: Added dependency for -lm.
6607 * acinclude.m4: Renamed from aclocal.m4.
6608 * PLUGIN/greet: Removed.
6609 * Makefile.am, aclocal.m4: New files.
6610 * configure.in: Updated for Automake.
6612 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6614 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6615 and not top_level_lookup_thunk_var.
6617 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6619 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6621 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6623 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6624 Scheme function, instead of syntax. Single argument is now a
6627 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6629 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6630 scm_ra_divide): Properly terminate statements passed as arguments
6631 to IVDEP macros. (Thanks to Bernard Urban.)
6633 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6634 with non-constant sizes. (Thanks to Bernard Urban.)
6636 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6638 It's an "eval closure", not an "eval thunk." A thunk is a
6639 function of no arguments.
6640 * root.h (struct scm_root_state): Renamed
6641 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6642 (scm_top_level_lookup_closure_var): Renamed from
6643 scm_top_level_lookup_thunk_var.
6644 * root.c (mark_root): Uses changed.
6645 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6646 * init.c (scm_start_stack): Uses changed.
6647 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6648 Change scheme-visible name to *top-level-lookup-closure* from
6649 *top-level-lookup-thunk*.
6651 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6653 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6654 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6656 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6658 * gc.c (struct scm_heap_seg_data): Doc fixes.
6660 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6661 sweeping. Then, prepend each segment's free cells to its
6662 freelist, rather than wiping out the old value. (Thanks to Marius
6665 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6666 scm_check_freelist, scm_debug_newcell): New functions and
6667 variables, for debugging freelist problems.
6668 * pairs.h (SCM_NEWCELL): New debugging version added.
6669 * gc.h (scm_debug_newcell): Added extern declaration, used by
6670 debugging version of SCM_NEWCELL.
6672 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6674 On some systems <libc.h> conflicts with <unistd.h>, and should not
6675 be #included at all.
6676 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6677 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6678 * configure.in: Call it.
6679 * posix.c, filesys.c: Use its results to decide whether or not to
6681 * configure, scmconfig.h.in: Rebuilt with autoconf and
6684 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6686 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6687 pointer to the stdio stream before calling scm_setbuf0, so the
6688 latter will be able to retrieve it. I'm surprised this didn't
6689 segfault earlier. (Thanks to Christopher Lee.)
6691 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6693 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6696 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6698 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6699 number of stack narrowing specifier pairs. The first specifier in
6700 a pair controls inner border, the second the outer border. A
6701 number means cut that number of frames, a procedure object means
6702 cut until that object is found in operator position in a frame.
6704 * root.c (cwdr): Bugfix.
6706 * read.c: Recording of positions disabled by default.
6708 * procs.c (scm_closure_p): New function.
6710 * posix.c (scm_tmpnam): New function.
6712 * load.c: Added #include "throw.h".
6713 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6716 * load.c, load.h (scm_read_and_eval_x): New function.
6718 * eval.c: Renamed debug option "deval" to "debug".
6720 (scm_eval_x): `eval!' is no longer accessible from the scheme
6721 level. Motivation: We can't allow operations which introduce
6722 glocs into the scheme level. Guile's type system can't handle
6723 these as data. Use `eval' or `read-and-eval!' as replacement.
6725 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6726 SCM_CONSP since this is a macro!; Set vframe.prev to
6727 scm_last_debug_frame instead of 0. In this way we can look
6728 "above" the virtual start stack frame if we wish.
6729 (scm_debug_hang): New function: Useful for debugging Guile in
6730 certain tricky situations. Will probably be removed later...
6732 * debug.h: Changed semantics of debug option "backtrace". This
6733 option now only indicates whether we want automatic backtrace at
6736 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6738 * ports.c: #include "filesys.h"
6739 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6741 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6742 Motivation: This is system specific code which is related to file
6743 I/O. It also may use select. Added code by Gary Houston to
6744 detect presence of character in stdio buffers.
6746 * libguile.h: #include "libguile/libpath.h"
6748 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6749 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6750 SCM_SITE_DIR; Install libpath.h among the other include files.
6752 * load.c, load.h (scm_sys_package_data_dir): New function.
6754 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6756 * stacks.h: Bugfix: Don't use tail-array length field as stack
6757 length field! This screwed GC.
6759 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6761 * _scm.h: Added #ifndef around definition of macros min and max.
6763 * __scm.h: Added hooks for threads to plugin to in ints protection
6764 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6765 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6766 the main code in these macros duplicated and spread over multiple
6767 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6768 SCM_THREAD_SWITCHING_CODE.
6770 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6772 * snarf.h: New file.
6773 * guile-snarf.sh: New file.
6774 * Makefile.in (inner_h_files): Added snarf.h
6775 (ancillary, install, uninstall, distclean): Added actions for
6777 (.c.x): Use guile-snarf.
6778 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6779 (gen_c_files): Note that these depend on guile-snarf.
6780 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6781 now in "snarf.h". Added #include "snarf.h" to get them.
6782 * libguile.h: Added #include "snarf.h".
6783 (Patches applied and tweaked by Jim Blandy.)
6785 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6787 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6788 standards suggest against providing prototypes for system
6789 functions. Thanks to Greg Troxel.
6791 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6793 * strports.c (scm_eval_0str): New function.
6794 #include "read.h", to get prototype for scm_read.
6795 * Makefile.in (strports.o): Update dependencies.
6796 * strports.h: New prototype.
6798 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6799 scheme name from "int?" to "integer?". It seems to do the job.
6800 * numbers.h: Rename prototype too.
6801 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6804 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6805 scm_num_eq_p): Rename these according to R4RS conventions: call
6806 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6807 to making libguile R4RS compliant without ice-9...
6809 * load.c (scm_sys_search_load_path): Search for files under all
6810 extensions listed in the %load-extensions variable. If FILENAME
6811 is absolute, return it unchanged, without searching the load path.
6812 (scm_loc_load_extensions): New variable, pointing to
6813 %load-extensions' value cell.
6814 (scm_init_load): Initialize it, and the value it points to.
6815 (scm_primitive_load_path): Improve error reporting.
6817 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6818 of new Scheme variable %load-hook.
6819 (scm_primitive_load): Apply %load-hook to filename.
6821 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6823 * configure.in: add tests for figuring out whether buffered data
6824 is available in a FILE structure, which is needed by char-ready.
6826 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6829 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6830 exceptions using misc_error instead of syserror. It seems a bit
6831 odd to throw an exception if a string can't be found in the
6832 environment, but it's consistent with open-file, stat etc.
6833 (simpos.h): remove sys_ from getenv.
6835 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6836 occurs, throw an error instead of returning errno. Return value
6838 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6840 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6842 * filesys.c (scm_stat2scm): derive file type and permissions from
6843 the stat mode and append them to the returned vector.
6844 There isn't much overhead in doing this and it avoids the need to
6845 work with S_IRUSR et al. in Scheme.
6846 Define symbols scm_sym_regular etc.
6847 (scm_init_filesys): don't intern S_IRUSR etc.
6849 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6850 and s_primitive_load_path.
6852 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6854 * error.h: don't declare error symbols. prototype for scm_misc_error.
6856 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6859 * error.c: use SCM_SYMBOL to set up error keys.
6860 scm_misc_error: new procedure.
6862 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6864 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6865 between `#!' and `!#' is ignored.
6866 (skip_scsh_block_comment): New function.
6868 * feature.c (scm_set_program_arguments): New argument, FIRST.
6869 * feature.h: Update prototype.
6870 * init.c (scm_boot_guile_1): Pass new argument to
6871 scm_set_program_arguments.
6873 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6875 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6876 (scm_boot_guile): Call scm_set_program_arguments here, later than
6877 the old initialization.
6879 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6880 initialization procedure.
6881 - Delete in, out, err arguments; there are other perfectly good
6882 ways to override these when desired.
6883 - Delete result argument; this function shouldn't ever return.
6884 - Rename init_func argument to main_func, for less confusion.
6885 - Delete boot_cmd argument; main_func is more general.
6886 -Add 'closure' argument, to help people pass data to main_func
6887 without resorting to global variables.
6888 - Abort if reentered; don't bother returning an error code.
6889 - Call scm_init_standard_ports to set up the default/current
6890 standard ports; no need to pass them to scm_start_stack.
6891 - Remove code to evaluate the boot_cmd, and start the repl; let
6892 the user do something like that in main_func if they want.
6893 - Remove code to package up a return value; main_func can do any
6895 - Call exit (0), instead of returning.
6896 (scm_start_stack): Don't initialize the I/O ports here; that's
6897 weird. Delete in, out, err arguments. Move guts to
6898 scm_init_standard_ports, scm_stdio_to_port.
6899 (scm_init_standard_ports): New function, to set up current and
6900 default standard ports.
6901 (scm_start_stack, scm_restart_stack): Make these static.
6902 * init.h (scm_boot_guile): Adjust declaration.
6903 (scm_start_stack, scm_restart_stack): Remove externally
6904 visible declarations for these.
6905 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6907 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6908 written out several times in scm_start_stack.
6909 * fports.h: New declaration for the above.
6911 * feature.c (scm_set_program_arguments): New function.
6912 * feature.h: New declaration for the above.
6914 * ports.c: Formatting tweak.
6916 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6918 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6919 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6920 for obtaining the address of a car or cdr field. Motivation:
6921 &SCM_CXR make assumptions about the internal structure of the
6924 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6925 Motivation: see SCM_CXRLOC.
6927 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6928 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6929 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6930 Motivation: Safer use. Some other macros are defined in terms of
6931 these operations. If these are defined using the SCM_SETCXR
6932 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6933 to inefficiency and an <e1> with side-effects could potentially
6934 break. Also, these particular operations are heavily utilized in
6935 the garbage collector. In unoptimized code there will be a
6938 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6939 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6940 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6941 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6942 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6943 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6944 vports.c: Cleaned up use of pairs: Don't make any special
6945 assumptions about the internal structure of selectors and
6946 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6947 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6948 (Among other things, this change makes it easier to build Guile
6949 with certain compilers which have problems with casted lvalues.)
6951 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6953 * stacks.c: Improve selection of relevant stack frames when making
6954 a stack object. Introduce one level of indirection in the stack
6955 object to make it possible to "narrow" to a certain region of the
6956 stack. This facilitates making use of more clever algorithms (not
6957 implemented) for selecting relevant frames and gives a cleaner
6958 design since selection of frames can be done independently of
6959 extraction of frames from the real stack.
6960 (scm_stack_id): Also take #t as argument which means look at
6963 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6964 Turn n_tail into an integer directly representing current number
6965 of frames in stack. Add field tail.
6967 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6969 * debug.c (scm_make_memoized): Made it available at scheme level.
6970 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6971 SCM_NIMP before applying heavier predicates in argument checking.
6972 (scm_local_eval): Also take memoized object as argument.
6974 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6975 aren't created with zero length, but should such a strange
6976 creature suddenly turn up...
6978 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
6980 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
6981 `del', for the sake of C++ compilers. (Patch applied by JimB.)
6983 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
6985 * variable.c (scm_make_variable): Make the name hint optional, as
6987 (anonymous_variable_sym): Renamed from variable_sym. All uses
6990 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
6991 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
6992 of scm_primitive_load_path was also changed to
6993 "primitive-load-path", from "%try-load-path". Callers changed.
6994 We'd like to respect the convention that a function named
6995 "try-mumble" should behave just like the function called "mumble",
6996 but return #f instead of signalling some error.
6997 * load.h: Rename prototypes.
6999 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7001 * print.c (make_print_state, grow_print_state), print.h: Modified
7002 the print state representation: Don't use a tail array for
7003 recording of circular references. Resizing of the print state
7004 structure invalidates the print state pointer. To avoid passing
7005 around an indirect print state reference to all printing
7006 functions, we instead let the print state reference a resizable
7009 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7011 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7012 Don't crash when passed an improper list terminated by a
7013 non-immediate value.
7015 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7017 Allocate data for structures on an eight-byte boundary, as
7018 required by the tagging system.
7019 * struct.c (alloc_struct): New function.
7020 (scm_make_struct, scm_make_vtable_vtable): Call it.
7021 * struct.h (scm_struct_n_extra_words): Bump to 3.
7022 (scm_struct_i_ptr): New "field".
7023 * gc.c (scm_gc_sweep): When we need to free the data, use the
7024 information stored by alloc_struct to find the beginning of the
7025 block allocated to the structure, so we can free it.
7027 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7029 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7032 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7033 (scm_debug_info): New member: id.
7035 * stacks.c: Stacks are now represented as structs; Stacks have an
7036 id given to them by `start-stack'.
7037 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7039 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7040 Changed stack representation.
7042 * debug.c (scm_procedure_name): Try procedure property `name' for
7043 compiled closures aswell.
7045 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7047 * eval.c: scm_i_name moved to gsubr.c
7048 (scm_m_define): Record names of all kinds of procedure
7049 objects. (Earlier, only closures were recorded.)
7051 * procprop.h: Added declaration of scm_i_name.
7053 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7054 (scm_make_gsubr): Record names of compiled closures.
7056 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7058 * debug.c, debug.h: Removed obsolete code.
7060 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7061 stacks.c: Renamed regs --> scm_contregs.
7063 * print.c (scm_free_print_state): Cleanup print state before
7064 returning it to pool. It is better to do it here than in
7065 scm_prin1 since scm_prin1 is called often.
7067 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7068 s_set_source_property_x): Check that first argument is a pair or a
7071 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7072 scm_i_line, scm_i_column and scm_i_breakpoint global.
7074 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7075 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7078 * debug.h: Added debug object smob declaration and macro
7081 * configure.in: Build with backtrace.o and stacks.o if debug
7084 * Makefile.in: Added entries for new files: backtrace.c,
7085 backtrace.h, stacks.c and stacks.h.
7087 * symbols.c (scm_sym2ovcell): Fixed documentation.
7089 * _scm.h (min, max): Added.
7091 * async.c: Moved `min' macro to _scm.h.
7093 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7094 SCM_BACKTRACE_INDENT.
7096 * eval.c: Added new debug options `maxdepth' and `indent'.
7098 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7100 * print.h: Added selector SCM_PRINT_STATE.
7102 * print.c: New functions: scm_make_print_state,
7103 scm_free_print_state.
7105 * print.h: Added declarations for scm_make_print_state,
7106 scm_free_print_state.
7108 * debug.c (scm_m_start_stack): New acro.
7110 * debug.h: Small cleanup.
7112 * init.c (scm_boot_guile_1): Moved scm_init_debug below
7115 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

7135 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
7136 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
7137 declare functions with prototypes. (Patch thanks to Marius
7140 More prototype-related changes from Marius Vollmer:
7141 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7142 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7143 * ports.h (ptobfuns): Added prototypes. This means some casting in
7145 * fports.c: Added casts for initializations, since the functions
7146 are defined to take FILE * as their stream argument, not SCM.
7147 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7148 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7149 to `char *str_data' to conform to prototype.
7151 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7153 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7155 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7157 * stime.c, stime.h: use SCM_P method.
7159 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7161 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7162 be given at least two arguments. Insist that lst's last element
7163 be a list, but don't make any requirements of its predecessors.
7165 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7167 * eval.c (scm_nconc2last): Revert last change; there seems to be
7168 other stuff going on here.
7170 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7172 * eval.c (scm_nconc2last): Make sure that each element of lst
7173 (which is a list of argument lists, except for the tail) is a
7174 proper list, i.e., finite and terminated by '().
7176 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7178 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7181 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7182 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7185 * vectors.c (scm_make_vector): Fill vectors with the undefined
7186 value, to help make Guile Scheme code more portable to other
7189 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7190 * symbols.h, tags.h: Doc fixes.
7192 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7194 * async.c (scm_take_signal): Doc fixes.
7196 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7198 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7199 want to subtract it from the modulus; we just want to leave it
7202 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7204 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7207 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7209 * throw.c (scm_catch_apply): Finished implementation of
7212 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7214 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7216 (scm_init_filesys): set "i/o-extensions" feature.
7219 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7221 * Makefile.in (root.o): Correct dependencies.
7223 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7225 * Makefile.in: Added dependency entry for root.o.
7227 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7228 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7230 * init.c (scm_start_stack): Set initial root continuation number
7233 * procs.c: New function: scm_thunk_p.
7235 * procs.h: Added declarations of scm_thunk_p.
7237 * root.c: Renamed `call-with-new-root' -->
7238 `call-with-dynamic-root'.
7239 (cwdr): Removed allocation of new root state. This should be done
7240 separately by use of scm_make_root.
7241 (scm_apply_with_dynamic_root): New function: Does what it
7242 sounds like. Needed when spawning threads.
7244 * root.h: Added member last_debug_frame to root state.
7245 Added #include "libguile/debug.h"
7247 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7248 arguments. The motivation is that code in root.c needs catch
7249 functionality, and we want to avoid code duplication.
7250 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7251 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7252 handlers that run without popping the stack into the dynwind
7255 * throw.h: Added prototypes for scm_catch_apply and
7258 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7260 * root.h (scm_root, scm_set_root): Decouple thread support details
7261 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7262 SCM_SET_THREAD_LOCAL_DATA.
7264 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7265 and tortoise scanning loop.
7267 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7269 * Makefile.in: Rebuild dependencies.
7271 * libguile.h: #include "libguile/print.h" before "smob.h", since
7272 the latter uses the print_state structure.
7274 * throw.c (scm_ithrow): Use the correct variable when checking to
7275 see if a given element of scm_dynwinds is a valid catch.
7277 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7278 structure, abort; don't just silently ignore the garbage.
7280 * _scm.h: #include "print.h" here, since it seems to be used just
7282 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7283 strports.c, unif.h: Don't #include "print.h".
7285 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7287 * feature.h (scm_loc_features): Removed external declaration.
7288 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7290 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7292 * feature.c (scm_init_feature): Added threads feature (needs to be
7293 initialized here, since features doesn't exist when
7294 scm_init_threads is called).
7296 * libguile.h: Added #include "libguile/../threads/threads.h".
7297 (This is a kludge to get thread support working. This should be
7300 * configure.in, acconfig.h: Added flags for thread support.
7302 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7305 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7306 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7309 * _scm.h: Added conditional #include "threads.h"
7311 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7312 SCM_THREADS_SWITCHING_CODE.
7314 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7315 allocate the basic dynamic root object.
7316 (scm_boot_guile): Added call to scm_init_root.
7318 * root.c, root.h: Added root smob.
7319 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7320 functions: Implements dynamic roots mostly according to spec in
7321 SCM manual. Main difference is that the second argument is a
7322 throw handler rather than an error "thunk".
7324 * root.h: Added declaration of scm_init_root.
7326 * root.c: Added #include "genio.h", #include "smob.h", #include
7327 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7329 (scm_init_root): Added #include "root.x".
7331 * throw.c: Added #include "stackchk.h"
7332 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7333 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7334 can be used in scm_call_with_new_root; Added reenabling of stack
7335 checking when catching a throw.
7337 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7339 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7341 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7342 element is not found, as per R4RS.
7344 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7346 * list.c: Doc fixes throughout.
7348 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7350 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7351 declare the char * to be const. Avoids a warning in rgx.c.
7353 * ports.h: spelling fix.
7355 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7358 * load.c (scm_sys_try_load_path): throw an error if file not found
7359 (like it says it in NEWS).
7361 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7363 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7364 PROPS slot to '(), not #f; it's an empty alist.
7366 * throw.h, throw.c: Use SCM_P instead of #if hair.
7368 Remove special support for uncaught throws; see throw.c for
7370 * throw.c (uncaught_throw): New function.
7371 (scm_ithrow): Call uncaught_throw if we don't find a throw
7372 target; don't mess with scm_bad_throw_vcell.
7373 (scm_bad_throw_vcell): Variable deleted.
7374 (scm_init_throw): Don't initialize it.
7376 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7379 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7381 * numbers.c (scm_istr2int): If the number is short (as most
7382 numbers are), just call scm_small_istr2int to deal with it.
7383 (scm_small_istr2int): New function, created by un-#ifdefing the
7384 non-bignum version of scm_istr2int and renaming it.
7386 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7388 * load.c (scm_sys_try_load): don't check whether value returned
7389 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7390 Change the Scheme name from %try-load to primitive-load.
7392 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7393 Can avoid passing a message, allowing it to be derived in the
7394 error handler (e.g., if we want to throw to the key both from
7397 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7399 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7400 references now have a new appearance which is more compact and
7401 also gives a clue about what the target of the reference is.
7402 By setting parameters in the print state, more fancy printing can
7403 be achieved. This is used by the (not yet commited) backtrace
7406 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7408 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7411 * print.c: Added #include "struct.h". Removed function
7414 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7415 scm_iprin1. Removed prototype for scm_prlist.
7417 * arbiters.c (prinarb),
7418 async.c (print_async),
7419 debug.c (prindebugobj, prinmemoized),
7420 eval.c (prinprom, prinmacro),
7421 filesys.c (scm_fd_print, scm_dir_print),
7423 mallocs.c (prinmalloc),
7424 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7425 smob.h (scm_smobfuns),
7426 srcprop.c (prinsrcprops),
7428 unif.c, unif.h (scm_raprin1, rapr1),
7429 variable.c (prin_var): Changed argument `int writing' to
7430 `scm_print_state *pstate'.
7432 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7433 that it will be called before scm_init_print.
7435 * print.c (scm_prin1): Print states are now allocated when calling
7436 scm_prin1 and then passed around to all printing functions as an
7437 argument. A cache `print_state_pool' enables reuse of print
7439 (scm_make_print_state): New function.
7440 (scm_iprin1): Adaption to print states.
7441 (scm_iprlist): An initial "hare and tortoise" scan brings down
7442 time complexity to O (depth * N). (Better time complexity will be
7443 achieved when the printing code is completely rewritten.)
7445 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7447 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7448 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7449 it gets done whether or not the cache variable has a value.
7451 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7453 Distinguish #f and ().
7454 * __scm.h: #undef SICP.
7455 * pairs.h (SCM_EOL): Delete this definition, equating it with
7457 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7458 the value it used to have. Doc fixes, too.
7460 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7462 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7463 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7464 Lord's implementation of structs, allowing for tail arrays as
7465 described in the manual. Also fixed some bugs. (Both the interface
7466 and the implementation should be improved.)
7468 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7470 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7471 People who whish to see the source can do `(print-enable 'source)'.
7472 Removed #ifdef DEBUG_EXTENSIONS.
7474 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7476 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7477 integer (assuming for now accepting an integer is a good thing).
7479 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7480 %S will be used instead for write'ing arguments.
7482 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7483 asserts. fix a few other asserts.
7484 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7485 scm_uniform_vector_ref, scm_array_set_x,
7486 scm_dimensions_to_unform_array): change args in
7487 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7488 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7489 scm_substring_fill_x): likewise.
7490 gsubr.c (scm_gsubr_apply): likewise.
7491 eval.c (SCM_APPLY): likewise.
7493 * eval.c (4 places): replace scm_everr with lgh_error or
7496 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7497 scm_memory_error): new procedures.
7498 scm_everr: deleted. can use scm_wta, dropping first two args.
7499 scm_error: convert NULL subr to SCM_BOOL_F.
7501 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7504 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7507 * error.c, error.h: new error keys: scm_arg_type_key,
7508 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7510 scm_wta: reimplement using lgh_error instead of scm_everr.
7512 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7514 * gdbint.c: scm_lread now has one more argument.
7516 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7517 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7518 loading source from non-file ports, which, e. g., happens when
7519 using the Emacs interface).
7521 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7524 * read.c: Added code for recording of positions of source code
7525 expressions; New functions: recsexpr, scm_lreadrecparen;
7526 _scm_make_srcprops --> scm_make_srcprops
7527 (scm_flush_ws): Removed updating of positions counters. This work
7528 is already done by scm_gen_getc
7530 * read.h: Added prototype for scm_lreadrecparen
7532 * print.c: Added #include "alist.h"
7534 * eval.c: Added #include "hash.h"
7536 * eq.c: Added #include "ramap.h"
7538 * options.c: Documentation fixes.
7540 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7541 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7542 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7543 --> scm_make_srcprops
7545 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7546 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7547 function calls in the definition of the whash access macros.
7549 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7551 * init.c (scm_boot_guile): Add level of indirection to
7552 scm_boot_guile_1() to ensure that stack base pointer is properly
7553 initialized. There was no guarantee that variable i was the
7554 highest/lowest variable on stack (i.e. the call frame of
7555 scm_boot_guile was not completely protected from gc).
7557 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7559 * ports.h (scm_port_table): put back file_name, it will be used to
7560 support debugging. Undo related changes in fports.c, ioext.c,
7563 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7565 * ports.h (scm_port_table): remove file_name member for now, it seems
7567 * fports.c (scm_open_file): don't set file_name in PTAB.
7568 (prinfport): don't use file_name in PTAB.
7569 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7570 * ports.c (scm_add_to_port_table): don't intialize file_name.
7571 (scm_port_file_name): remove for now.
7572 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7574 * fports.h (scm_mkfile): prototype deleted.
7575 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7577 * debug.c, unif.c: use scm_out_of_range instead of
7578 wta for range errors (ASSERT still needs work).
7580 * error.c, error.h (scm_out_of_range): new procedure.
7582 * error.c, error.h (scm_out_of_range_key): new key.
7584 * posix.c (scm_sync): #else was missing.
7586 * error.c, error.h: append _key to names scm_num_overflow and
7589 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7590 of consing an empty list.
7591 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7592 of macros, saves code and string space.
7593 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7594 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7595 lower case. Rename scm_syserror_m to scm_syserror_msg.
7596 error.h: prototypes for new procedures.
7598 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7600 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7602 * error.c, error.h: setup scm_num_overflow key.
7604 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7605 Remove definition of SCM_OVSCM_FLOW.
7607 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7609 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7610 explicit message and args.
7612 * error.c, error.h, __scm.h: change system_error_sym to
7615 * error.c (system_error_sym): remove leading %% from the Scheme name
7618 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7620 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7622 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7623 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7624 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7625 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7626 renamed. (These were introduced by unsupervised name
7629 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7631 * print.c: Added code for detection of circular references during
7632 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7633 a hook for printing of closures (accessible via print options).
7634 This leads to a split of calls to scm_iprin1 into two classes:
7635 elementary print operations (e. g. the code which prints a smob)
7636 still use scm_iprin1 while top level calls (like scm_display) use
7637 scm_prin1. scm_prin1 begins by clearing the data structure used
7638 to record reference information.
7640 * print.h: Added declarations of scm_prin1 and scm_prlist.
7642 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7644 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7646 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7648 * error.c (err_head): scm_iprin1 --> scm_prin1
7650 * debug.c: Adjusted header comment.
7654 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7656 * strerror.c: Doc fix.
7658 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7660 * gdbint.c (gdb_read): Now possible to run during GC.
7661 (unmark_port, remark_port): New functions.
7663 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7665 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7666 of allocating a new string object. Also, increase size by
7667 the factor 2 instead of 1.5.
7669 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7671 * __scm.h (SCM_P): Corrected to run under traditional C.
7673 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7676 * async.c: Calls to scm_sysintern corrected.
7678 * async.h (scm_async_clock): Redundant declaration removed.
7680 * continuations.c (scm_dynthrow): Redundant declaration removed.
7682 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7683 Definition typos corrected.
7685 * debug.h: Missing declarations of functions in debug.c added
7688 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7689 Missing declarations to functions in eval.c added.
7691 * filesys.c: Possibly uninitialized variable rv.
7693 * gc.h (scm_object_addr, scm_unhash_name): Missing
7694 declarations of functions defined in gc.c added.
7696 * genio.c: Possible typos str_data -> wstr_data. ???
7698 * genio.c: Possibly unintended shadowing of local variable
7699 `int c' (gotos out of scope of inner `c'). ???
7701 * init.c: Uninitialized `SCM last' may be used.
7703 * ioext.h: (scm_sys_isatty_p): Typo.
7705 * list.h (scm_list_head): Missing prototype for function in
7708 * numbers.c (scm_two_doubles): Changed from extern to static
7709 (is used only within numbers.c).
7711 * numbers.h: Repeated declarations removed.
7713 * ports.h (scm_close_all_ports_except): Declaration for the
7714 function defined in ports.c added.
7716 * posix.h: Missing declarations added.
7718 * procs.h (scm_make_subr_opt): Missing declaration added.
7720 * socket.h (scm_sys_gethost): Missing declaration added.
7722 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7724 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7725 Missing declarations added.
7727 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7729 * struct.c: Uninitialized variable `SCM answer' may be used.
7731 * unif.c (l2ra): Declaration prototype.
7733 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7734 defined in ramap.c).
7736 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7737 Redundant declarations removed (they are in ramap.h).
7739 * variable.h (scm_make_udvariable,
7740 scm_make_undefined_variable): Declaration corrected to
7741 correspond variable.c.
7743 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7744 Missing declarations added.
7746 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7748 * Makefile.in (distclean): Don't forget to delete fd.h.
7750 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7752 * fd.h.in, tags.h: Trivial cleanups.
7754 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7755 marksweep.h just declared functions from gc.c.
7756 * gc.h, libguile.h: Don't #include "marksweep.h".
7757 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7758 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7759 dependencies updated.
7761 * libguile.h: Don't #include "files.h"; it's been deleted.
7763 * files.c (scm_sys_delete_file): Moved to filesys.c.
7764 File is now empty; deleted.
7766 * filesys.c: scm_sys_delete_file is now here. Remove
7767 #if's; they seem to rely on remnants of an old portability
7768 regimen. If the problems come up again, solve them properly,
7769 using autoconf. Specifically: Don't test M_SYSV, and #define
7770 remove to be unlink if it's #defined; don't use remove just
7771 because HAVE_STDC_HEADERS is #defined.
7772 * filesys.h: Add declarations for scm_sys_delete_file.
7773 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7774 files.o, files.h, files.c, and files.x.
7775 * init.c: Don't #include "files.h", and don't call scm_init_files.
7777 Use SCM_P instead of PROTO; the latter intrudes on the user's
7779 * params.h: Deleted; definition of SCM_P moved to...
7780 * __scm.h: ... here, where it replaces PROTO macro.
7781 * libguile.h, smob.h: Don't #include "params.h".
7782 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7783 smob.h: Fix prototypes accordingly.
7784 * Makefile.in: Update dependencies.
7785 (inner_h_files): Remove params.h.
7787 * gc.c: #include "gc.h"; every module should include its header,
7788 to let the compiler cross-check the declarations against the
7791 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7792 simpos.h: #include "libguile/__scm.h".
7794 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7796 * init.c: Don't forget to #include smob.h and init.h.
7797 * Makefile.in: Dependencies updated.
7799 * smob.h: Use PROTO instead of #if __STDC__.
7801 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7803 * __scm.h: Doc fixes.
7805 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7806 <angles>; this allows `make depends' to work properly.
7808 * libguile.h: #include smob.h and pairs.h before the others; they
7809 define typedefs used by other headers.
7811 C files should #include only the header files they need, not
7812 libguile.h (which #includes all the header files); the pointless
7813 recompilation was wasting my time.
7814 * Makefile.in (all .o dependency lists): Regenerated.
7815 * libguile.h: Don't try to get a definition for size_t here...
7816 * __scm.h: Do it here.
7817 * _scm.h: Since this is the internal libguile header, put things
7818 here that all (or a majority) of the libguile files will want.
7819 Don't #include <libguile.h> here; that generates dependencies on
7820 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7821 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7822 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and
7824 * alist.c: Get "eq.h", "list.h", "alist.h".
7825 * append.c: Get "append.h", "list.h".
7826 * arbiters.c: Get "arbiters.h", "smob.h".
7827 * async.c: Get "async.h", "smob.h", "throw.h", "eval.h".
7828 * boolean.c: Get "boolean.h".
7829 * chars.c: Get "chars.h".
7830 * continuations.c: Get "continuations.h", "dynwind.h", "debug.h",
7832 * debug.c: Get "debug.h", "feature.h", "read.h", "strports.h",
7833 "continuations.h", "alist.h", "srcprop.h", "procprop.h", "smob.h",
7834 "genio.h", "throw.h", "eval.h".
7835 * dynwind.c: Get "dynwind.h", "alist.h", "eval.h".

7919 * weaks.c: Get "weaks.h".
7921 * stackchk.h: #include "libguile/debug.h",
7923 * print.h, read.h: #include "options.h", since everyone who uses
7924 either of these files will need that.
7926 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7927 anyone who uses this file will need them to define the smob
7928 printing functions. Also, get markers.h, since people will need
7929 to #define the mark functions.
7931 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7932 * ports.h: ... to here.
7934 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7935 don't rely on archaic C default type rules.
7937 * fports.h: #include "libguile/ports.h", since you need that in
7938 order to parse this.
7940 * genio.h: #include "libguile/print.h", because you need that to
7941 parse this; don't bother #including "ports.h", since print.h gets
7944 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7946 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7947 this; it's now a reference to an element of *scm_root.
7949 * debug.h: Don't #include "options.h"; the compiler won't be able
7950 to find that once the headers are installed; instead, #include
7951 "libguile/options.h".
7952 * gc.h: Same, with marksweep.h.
7953 * mbstrings.h: Same, with symbols.h.
7954 * scmhob.h: Same, with _scm.h.
7955 * smob.h: Same, with params.h.
7957 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7958 C files; there's no need for this, and it forces recompilations
7961 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7963 * error.c (scm_error): declare scm_error_callback.
7965 * error.h: prototype for scm_error_callback.
7967 * __scm.h: define lgh_error.
7968 (SCM_SYSERROR): redefine using lgh_error.
7970 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7972 * error.c (scm_error): new procedure.
7974 * error.h: prototype for scm_error.
7976 * Makefile.in (install): install scmconfig.h from the current
7977 directory, not $(srcdir).
7979 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7981 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7982 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7983 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
7984 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
7985 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
7986 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,

7988 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7989 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7990 vports.h, weaks.h: #include "libguile/__scm.h", not
7991 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
7992 dependencies are within libguile properly.
7994 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7996 * Makefile.in (.c.x): Simplify; there's no need to run this rule
7997 when scmconfig.h doesn't exist.
7999 * load.c (scm_sys_try_load): Correct spelling.
8001 * feature.c (scm_loc_features): Make this static.
8003 * Makefile.in (libpath.h): Omit trailing slash from path. We
8004 shouldn't require it of users, so why put it here?
8006 Move code to initialize and search %load-path from ice-9 to C
8007 code, so we can use the load-path to find the ice-9 boot code;
8008 this makes it easier to run Guile without installing it. See
8009 corresponding changes in guile/Makefile.in.
8010 * feature.c: Move stuff concerned with the load path to load.c.
8011 (scm_compiled_library_path): Deleted.
8012 Don't #include libpath.h here.
8013 * feature.h: Don't mention scm_compiled_library_path.
8014 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8015 <sys/stat.h>, and <unistd.h> (if present).
8016 (R_OK): #define if the system hasn't deigned to.
8017 (scm_loc_load_path): New variable.
8018 (scm_init_load_path, scm_sys_search_load_path,
8019 scm_sys_try_load_path): New functions.
8020 (scm_init_load): Initialize scm_loc_load_path to point to the
8021 value cell of the Scheme %load-path variable.
8022 * load.h: Add declarations for scm_sys_search_load_path,
8023 scm_sys_try_load_path.
8024 * init.c: Call scm_init_load_path.
8025 * Makefile.in (feature.o, load.o): Dependencies updated.
8027 * load.c, load.h: Rewrite using PROTO macro.
8029 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8031 * gc.c (scm_cellp): New function: C predicate to determine if an
8032 SCM value can be regarded as a pointer to a cell on the heap.
8034 * gc.h: Added declaration of scm_cellp.
8036 * gdb_interface.h: New file: The GDB interface header from the GDB
8039 * gdbint.c: New file: GDB interface.
8041 * gdbint.h: New file: GDB interface.
8043 * libguile.h: Added #include <libguile/gdbint.h>.
8045 * init.c (scm_boot_guile): Added scm_init_gdbint.
8047 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8048 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8049 found if object files and source are kept separate).
8051 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8053 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8055 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8057 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8058 TK_SRC_DIR; they're not relevant any more.
8060 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8061 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8063 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8065 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8066 search path, so we can find the <libguile/MUMBLE.h> headers.
8068 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8070 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8071 implicit in the .c.o rule.
8072 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8075 Put the library path in a header file, instead of passing it on
8076 the command line in every compilation.
8077 * Makefile.in (libpath.h): New target.
8078 (feature.o): Depend on libpath.h.
8079 (clean): Delete libpath.h.
8080 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8081 * feature.c: ... #include "libpath.h" here.
8082 * .cvsignore: Ignore libpath.h.
8084 Don't install the unwashed masses of Guile header files in the
8085 main #include path; put most of them in a subdirectory called
8086 'libguile'. This avoids naming conflicts between Guile header
8087 files and system header files (of which there were a few).
8088 * Makefile.in (pkgincludedir): Deleted.
8089 (innerincludedir): New variable; this and $(includedir) are enough.
8090 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8091 (installed_h_files): Divide this up. Now this variable lists
8092 those header files which should go into $(includedir) (i.e. appear
8093 directly in the #include path), and ...
8094 (inner_h_files): ... this new variable says which files appear in
8095 a subdirectory, and are referred to as <libguile/mumble.h>.
8096 (h_files): List them both.
8097 (install): Create innerincludedir, not pkgincludedir. Put
8098 the installed_h_files and inner_h_files in their proper places.
8099 (uninstall): Corresponding changes.
8100 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8101 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8102 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8103 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8104 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8105 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8106 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8107 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8108 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8109 vports.h, weaks.h: Find __scm.h in its new location.
8110 * __scm.h: Find scmconfig.h and tags.h in their new locations
8111 (they're both "inner" files).
8113 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8115 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8117 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8119 * posix.c: Doc fixes.
8121 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8123 * socket.c: Don't include a prototype for inet_aton; just use a
8124 K&R style declaration, to avoid warnings but minimize the chance
8125 of conflicts with the system.
8127 On NextStep, <utime.h> doesn't define struct utime, unless we
8128 #define _POSIX_SOURCE before #including it.
8129 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8130 * acconfig.h: New comment text for above CPP symbol.
8131 * configure.in: Call it.
8132 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8134 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8136 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8137 testing for __EMX__.
8139 * posix.c: #include <libc.h>, if it exists.
8141 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8142 don't even know if the latter exists.
8144 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8145 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8146 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8148 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8150 (scm_init_posix): Use them when initializing the Scheme constants
8153 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8155 * Makefile.in (libdir, includedir, bindir): Use the
8156 autoconf-supplied values, instead of deriving them ourselves.
8157 (pkgincludedir, datadir, pkgdatadir): New variables.
8158 (install, uninstall): Put the header files in a special
8159 subdirectory, not in the main search path.
8161 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8162 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8164 * Makefile.in (IMPLPATH): Deleted; never used.
8166 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8167 on the Tcl/Tk source any more.
8168 (INCLUDE_CFLAGS): Remove references to the above.
8170 * Makefile.in (version.o): Corrected dependencies.
8172 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8174 * libguile.h: #include "version.h"
8176 * init.c (scm_boot_guile): Call scm_init_version.
8177 * gscm.c (gscm_run_scm): Call scm_init_version.
8179 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8180 GUILE_VERSION): AC_DEFINE these.
8181 (acconfig.h): #undef the above symbols.
8183 * Makefile.in (libobjs): Add version.o.
8184 (installed_h_files): Add version.h.
8185 (c_files): Add version.c.
8186 (gen_c_files): Add version.x.
8187 (version.o): New rule.
8188 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8189 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

8198 weaks.o): Add version.h to dependency lists.
8199 (markers.o): Remove duplicate rule.
8201 * version.h: New file.
8203 * version.c: New file.
8205 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8207 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8208 array; use it appropriately. Since GCC is quite happy to
8209 subscript functions, it never warned us about this; we should use
8210 -Wpointer-arith in the future. I guess we never tested
8213 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8215 * socket.c: Doc and copyright fixes.
8217 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8219 * debug.c: Fixed and improved gdb support.
8221 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8223 * socket.c: Added declaration of inet_aton to avoid compiler
8224 warning. (Hope this solution is correct.)
8226 * stime.c: Added declaration of ftime. (This is missing in
8229 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8231 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8233 * Makefile.in (c_files): add strerror.c.
8235 * strerror.c: new file from Emacs' sysdep.c.
8236 maybe configure should also check for sys_errlist.
8238 * configure.in (AC_REPLACE_FUNCS): add strerror.
8240 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8242 * debug.c (scm_init_debug): Added initialization for
8243 scm_evaluator_traps.
8245 * debug.h, debug.c: Various name changes.
8246 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8247 "debug-options-interface". See commentary in options.c.
8249 * options.h, options.c: Options now have documentation strings.
8250 Also added a long explanatory commentary.
8252 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8255 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8256 last_debug_info_frame is now updated in all cases.
8258 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8261 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8263 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8264 Added option STACK_CHECKING.
8266 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8268 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8270 * __scm.h: Removed symbols for debugging support.
8272 * acconfig.h: Added symbols for debugging support.
8274 * configure.in: Added user option for debugging support.
8275 --enable-debug will include the debugging code into libguile.a.
8277 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8278 scm_relocate_chunk_to_heap.
8280 * debug.c: New file: low-level debugging support. It also
8281 includes support for debugging with gdb. (The extensions to gdb
8282 are written by Per Bothner at Cygnus.)
8284 * debug.h: New file: low-level debugging support.
8286 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8287 argument pairs. Extensive modifications to the debugging
8288 evaluator. Added "SECTION:" commentaries to clarify what happens
8289 when, during double compilation. Renamed EVALIMP --> EVALIM.
8290 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8291 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8292 the beginning of the file. New procedure: scm_unmemocopy.
8293 Added some global state variables needed by the debugging
8294 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8295 check_entry, check_apply, check_exit, debug_options and
8296 evaluator_traps. New acro: undefine.
8298 * eval.h: Renamed EVAL --> XEVAL.
8300 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8301 --> scm_make_weak_key_hash_table.
8303 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8304 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8306 * libguile.h: Conditionally include debug.h
8308 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8309 scm_object_properties shouldn't return handle. `handle' now gets
8310 initialized in scm_set_object_properties_x. scm_object_properties
8311 doesn't any longer create an entry in scm_object_whash.
8313 * options.c: New file: handling of run time options.
8315 * options.h: New file: handling of run time options.
8317 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
8319 * print.c: New procedure: scm_print_options
8321 * print.h: Defines for print options.
8323 * read.c: New procedure: scm_read_options
8325 * read.h: Defines for reader options.
8327 * root.h: Added scm_source_whash among scm_sys_protects.
8329 * srcprop.c: New file: source properties.
8331 * srcprop.h: New file: source properties.
8333 * throw.c (jbsmob): Jump buffers are now correctly allocated.
8334 (Bug found by A. Green.)
8336 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8338 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8340 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8342 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8344 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8345 and should be called by the final client.
8347 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8349 * gc.h: Use the PROTO macro when declaring functions.
8350 * gc.c: Use the PROTO macro when declaring static functions.
8351 Remove the CPP hair around function definitions.
8353 * gc.c (scm_init_storage): Initialize scm_asyncs.
8355 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8356 preprocessor symbol; "__scm.h" is where it might get #defined.
8357 * __scm.h: Similar: #include <scmconfig.h> before testing
8360 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8362 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8364 * init.c (scm_boot_guile): Add init_func argument; call
8365 (*init_func) instead of calling scm_appinit; it's ucky to
8366 hard-code names for the user's procedures.
8367 * init.h (scm_boot_guile): Adjust declaration.
8369 * __scm.h (PROTO): New macro, for declaring functions with
8372 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8373 eliminate all the __STDC__ conditionals.
8374 (scm_boot_guile): Add declaration.
8375 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8376 Remove __STDC__ conditionals around function definitions; the
8377 declarations in init.h will provide the same information, more
8380 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8381 complain about it in the error message; the error message is
8382 adequate without that note, and there's nothing the user can do
8385 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8387 * Makefile.in (ancillary): Drop def.sed.
8389 * posix.c (scm_init_posix): Use numeric values, rather than
8390 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8391 F_OK. The symbols aren't available on some systems, and I'm
8392 pretty sure their values are fixed by common widespread practice.
8393 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8395 More functions unavailable on some systems.
8396 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8397 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8399 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8400 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8401 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8402 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8403 stub that signals an error as the #else.
8405 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8407 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8409 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8411 * unif.c: include ramap.h.
8413 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8415 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8417 * ports.c: include sys/ioctl.h.
8419 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8421 * configure.in: check for sys/ioctl.h.
8423 * ports.c: include <malloc.h> not "malloc.h".
8425 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8427 * fports.c: remove ttyname and tmpnam declarations.
8429 * posix.c: fewer ttyname declarations.
8431 * fports.c: include <string.h> not "string.h".
8433 * init.c, ioext.c: include string.h and unistd.h.
8435 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8437 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8438 genio.c, simpos.c, vports.c: include string.h.
8440 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8442 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8444 (scm_addr_buffer_size): change type from scm_sizet to int.
8445 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8446 from scm_sizet to int.
8448 * error.c: include unistd.h.
8450 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8453 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8455 * __scm.hd, def.sed: deleted.
8457 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8459 Changes for NeXT, suggested by Robert Brown.
8460 * configure.in: Call AC_TYPE_MODE_T.
8461 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8462 NeXT. Put header file list in alphabetical order.
8463 * configure, scmconfig.h.in: Regenerated.
8464 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8466 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8469 * acconfig.h: New file, providing documentation for the CPP
8470 symbols defined in configure.in
8471 * acconfig-1.5.h: Removed; superceded by the above.
8473 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8475 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8477 * fports.c (scm_open_file): don't return #f, throw error.
8479 * ioext.c (fileno): renamed from %fileno.
8480 (soft-fileno): deleted.
8482 * ports.c (scm_port_revealed): don't need to check for -1 from
8484 (scm_set_port_revealed_x): return unspecified, not #f.
8486 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8488 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8490 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8492 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8494 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8496 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8497 This is necessary on Ultrix, and doesn't hurt portability.
8499 * Makefile.in (dist-dir): New target, implementing a new dist system.
8500 (installed_h_files): Put in alphabetical order.
8501 Remove duplicate entries for markers.h and unif.h.
8502 (c_files): Remove duplicate entries for markers.c.
8503 (ancillary): Renamed from anillery; all uses changed. Remove
8504 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8505 Remove all the ../doc/* files; doc/Makefile.in handles that.
8507 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8509 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8510 every if must have an else, or else the whole command has a
8511 non-zero exit code whenever the if's condition is false.
8513 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8515 * posix.c: include string.h.
8517 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8519 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8522 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8523 Remove leading % from scheme names.
8524 Do not return error values, call SCM_SYSERROR or similar.
8526 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8528 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8530 * struct.c (scm_init_struct): new file.
8532 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8534 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8535 (scm_list_head): added list-head for rapidly chopping argument
8536 lists off of longer lists (and similar).
8538 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
8540 * objprop.c (scm_object_property): assq the cdr of the whash
8541 handle for obj, not the handle itself.
8543 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8545 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8546 weak hash tables last of all marking to avoid an obscure gc bug.
8547 WARNING: circular lists stored in a weak hash table will hose us.
8549 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8551 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8552 new functions similar to scm_substring_move_left_x and
8553 scm_substring_move_right_x.
8555 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8557 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8560 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8562 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8564 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8566 * strports.c (scm_strprint_obj): convenience function. C for
8567 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8569 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8570 removed to a separate library
8572 * init.c (scm_boot_guile): copied from guile-tcl.c.
8573 Initialization specific to tcl interpreters removed.
8575 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8577 * ports.c (scm_ports_prehistory): size malloced here doesn't
8578 matter so long as it is non-0 (got rid of "* 4").
8580 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8582 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8583 since its definition was bogus).
8585 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8587 * mallocs.[ch]: back again (for rx at least).
8589 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8591 * ports.c: removed functions relating to the mapping between ports
8592 and descriptors. (That stuff is unix-specific and should be collected
8593 in a separate library).
8595 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8596 (Tom Mckay@avanticorp.com)
8598 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8600 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8601 handled correctly (SCM_FREEP was applied to them) -- test for
8602 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
8603 being overwritten with #f. (brown@grettir.bibliotech.com)
8605 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
8607 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
8608 for a specific symbol or for all symbols.
8610 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
8612 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
8613 keys and weak values confused).
8615 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
8617 * list.c (scm_last_pair): map '()=>'()
8619 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>

8622 Generalized assoc and hash-table functions.
8623 Factored pairs.c into multiple files.
8625 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
8627 * gscm.c (gscm_run_scm): got rid of objprop.
8629 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
8631 * genio.c (scm_getc):
8632 NOTE: fgetc may not be interruptable.
8634 * procprop.c (scm_stand_in_scm_proc):
8635 NOTE: don't use a alist here.
8636 (scm_set_procedure_properties_x): fix type checking throughout this file.
8638 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
8640 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
8641 after freeing part of the port table.
8643 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
8645 * strports.c (scm_mkstrport):
8646 * vports.c (scm_make_soft_port): allocate a port table entry
8647 (possibly triggering gc) before setting the tag of the corresponding
8650 * pairs.c (scm_delq_x): never throw an error.
8652 * vectors.c (scm_make_vector): made the default vector fill argument
8653 into '() (much more useful than the previous value, "#unspecified")
8655 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
8657 * ports.c (scm_add_to_port_table): Added fields
8658 to port table entries: file_name, line_num, col.
8659 Update these in open_file, gen_getc and gen_ungetc.
8660 Added procedures to access those fields.
8662 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
8664 * procs.c (scm_make_subr_opt): new entry point for making
8667 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
8669 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
8671 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
8673 * numbers.c (scm_exact_p): This function no longer
8674 implements "integer?".
8676 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
8678 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
8679 (scm_gc_stats): return an assoc of useful data. Replaces "room"
8680 and the stats reporting formerlly built into repl.
8682 * repl.[ch]: removed.
8683 GC statistics keeping moved to gc.c.
8684 Other statistics keeping can be done from Scheme.
8685 REPLS are now written in Scheme.
8687 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
8689 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
8690 conservatively marked objects).
8692 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
8694 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
8696 * feature.c (scm_compiled_library_path): moved here from repl.c.
8697 This file is for stuff relating specifically to Scheme libraries
8700 * eval.c (scm_m_define): don't give warning about redefinition, don't
8703 NOTE: this should throw a resumable exception with parameters --
8704 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
8706 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
8708 * error.c: scm_warn eliminated.
8710 * read.c (scm_lreadr): extra right paren gets an error, not a warning.

8713 lose exit_report, growth_mon.
8715 * gscm.c: got rid of verbosity functions.
8717 Tue Feb 20 00:19:10 1996 Tom Lord <lord@beehive>
8719 * throw.c (scm_ithrow): guard against the bad-throw hook changing
8720 between the call to procedurep and use.
8722 * error.c (scm_everr):
8724 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
8727 * strports.c: don't reveal the port's string to the caller
8728 because it changes size.
8730 (stputc stwrite): check/change the strings length with interrupts
8733 * objprop.c (scm_set_object_property_x &c): use the generic
8734 hashing functions and be threadsafe.
8736 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
8737 (per suggestion jaffer@gnu.ai.mit.edu).
8739 * mbstrings.c (scm_multi_byte_string): guard against argument list
8742 * strings.c (scm_make_string): loop cleanup
8744 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
8747 * weaks.c (scm_weak_vector): guard against argument list
8750 * variable.c (scm_builtin_variable): check for/make a built-in
8753 * vectors.c (scm_vector): while filling the new array,
8754 guard against a list of fill elements that grows after
8755 the vector is allocated.
8757 * hashtab.c -- new file: general hash table
8758 functions. hash, hashq, hashv, hashx.
8760 * tags.h: made wvect an option bit of vector.
8762 Mon Feb 19 09:38:05 1996 Tom Lord <lord@beehive>
8764 * symbols.c: made the basic symbol table operations atomic.
8766 * root.c &c.: collected stack-specific global state.
8767 linum/colnum etc *should* be port-specific state.
8769 * struct.c (scm_init_struct): init the first struct type during
8770 initialization to fix a race condition.
8772 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
8773 object, not in a global.
8774 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
8776 * throw.c (_scm_throw): Pass throwval on the stack, not in a global
8777 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
8779 * *.[ch]: namespace cleanup. Changed all (nearly) exported CPP
8780 and C symbols to begin with SCM_ or scm_.
8782 Sun Feb 18 15:55:38 1996 Tom Lord <lord@beehive>
8784 * gsubr.c (scm_gsubr_apply): statically allocate the
8785 array of arguments (bothner@cygnus.com).
8787 Sat Feb 17 20:20:40 1996 Tom Lord <lord@beehive>
8789 * scmsigs.c: Simplified to use async rountines.
8791 * async.c: New support for interrupt handlers.
8793 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
8795 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
8796 set the multi_byte flag correctly in symbols. This is wrong.
8797 intern_obbary_soft and msymbolize should take an extra parameter.
8798 Also, weird multibyte symbols don't print correctly.
