1 1999-09-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3 * srcprop.c (scm_source_property): Bugfix: Use SCM_NECONSP instead
4 of SCM_NCONSP. (Thanks to Greg Badros.)
6 * gsubr.c (scm_make_gsubr): Use scm_make_subr_opt for creation of
9 * eval.c, debug.h (SCM_BACKTRACE_WIDTH): New debug option: width.
11 * backtrace.c: Keep backtraces within specified width by
12 adaptively adjusting fancy printing parameters and cut output if
14 (scm_display_application): Check args.
16 1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
18 Change the name of the objects returned by OPENDIR from
19 "directory" to "directory stream". A predicate named "directory?"
21 * filesys.c (scm_directory_stream_p): Renamed from scm_directory_p.
22 At the Scheme level, "directory?" -> "directory-stream?".
23 (scm_dir_print): Use the phrase "directory stream" in printed form.
24 * filesys.h (scm_directory_stream_p): Prototype renamed
27 * Makefile.am (CLEANFILES): Remove versiondat.h; that should only
28 be removed by `make distclean', since it's generated by configure.
29 * Makefile.in: Regenerated.
30 (Thanks to Robert Bihlmeyer.)
32 * strop.c (scm_substring_move_x): Signal an error if start1
33 doesn't come before end1. (Thanks to Karoly Lorentey).
35 * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
36 calling SCM_NIMP. (Thanks to Karoly Lorentey).
38 * version.c (scm_libguile_config_stamp): Deleted. See
39 corresponding change to ../ice-9/boot-9.scm.
40 * versiondat.h.in: Remove definition for GUILE_STAMP.
41 * version.h: Delete prototype.
42 * Makefile.in: Regenerated.
44 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
46 * filesys.c (scm_directory_p): new procedure "directory?" Returns
47 a boolean indicating whether its argument is a directory
48 port as returned by opendir (thanks to Dirk Herrmann for the
51 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
53 * backtrace.c (display_frame_expr): Don't print a newline.
54 (display_frame): Print the newline here instead.
55 (display_backtrace_body): Don't print "Backtrace:".
56 (scm_backtrace): Print "Backtrace:" here instead.
58 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
60 * procs.c (scm_setter): Signal WTA if handed an entity or operator
63 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
64 primitives. (Thanks to Greg Badros);
65 (scm_hook_to_list): New primitive; Hooks are now smobs.
67 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
69 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
70 of #f for the 10th vector element to avoid an exception
71 seen by Bernard Urban.
72 (scm_mktime): unneeded ASSERT removed.
74 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
76 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
79 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
81 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
83 * numbers.c: Converted comparison operations to dispatch on
84 generic if args don't match.
86 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
88 1999-09-06 James Blandy <jimb@mule.m17n.org>
90 * guile-snarf.c: Deleted. Snarfing should respect CPP
91 conditionals, so it needs to actually run CPP. Bleah.
93 1999-09-05 James Blandy <jimb@mule.m17n.org>
95 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
96 * guile-snarf.in: Be sure to exit with an error if CPP does.
97 * Makefile.am (.c.x): Delete the .x file and exit with an error
98 status if guile-snarf exits with an error status.
99 * Makefile.in: Regenerated.
101 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
102 scm_makekey, which doesn't exist any more. Guess nobody's using
105 * guile-snarf.c: New implementation of guile-snarf, meant to be
106 more robust than the shell script. I think it's complete, but I
107 haven't tested it at all, and I haven't changed the build process
108 to actually use it. We should compare its output against that of
109 the existing shell script, for all source files.
111 * guile-snarf.c (parse_args): Abort if we haven't handled some
114 1999-09-03 James Blandy <jimb@mule.m17n.org>
116 * load.c (scm_search_path): If the filename has any extension at
117 all, ignore the entire list of extensions. Also, don't check whether
118 the file is accessible. If the file exists, accessible or not, we
119 should return it. Inaccessible files should cause an error later.
120 (Thanks to Keisuke Nishida for the suggestions.)
122 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
124 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
125 atexit not available. (sunos4.1.4 needs it.)
127 1999-09-01 James Blandy <jimb@mule.m17n.org>
129 I take it all back --- bcopy does handle overlapping source and
130 destination areas correctly. At least on every system I could
131 find. But it is better to use AC_REPLACE_FUNCS than to introduce
132 new CPP conditionals.
133 * memmove.c: New file, implementing memmove in terms of bcopy.
134 * scmconfig.h.in: Regenerated.
136 Allocators should use the `void *' type for generic pointers.
137 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
138 argument and return types.
139 * gc.h: Corresponding changes to prototypes.
142 1999-08-31 James Blandy <jimb@mule.m17n.org>
144 * numbers.c (scm_init_numbers): Claim to support the `complex'
145 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
147 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
148 find (ice-9 boot-9) when Guile was compiled in a separate
149 directory from the source. (Thanks to Rodney Brown.)
150 * Makefile.in: Regenerated.
152 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
153 table lengths by the size of a single element when growing the
154 table. (Thanks to Bill Schottstaedt.)
156 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
158 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
159 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
160 since that cuts down the time for type dispatch by 50%.
162 1999-08-30 James Blandy <jimb@mule.m17n.org>
164 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
165 not a correct substitute for memmove, because it doesn't handle
166 overlapping source and destination areas on many platforms.
167 Overlaps are the primary reason to use memmove in the first place.
168 * ports.c (scm_ungetc): Same.
169 * strop.c (scm_substring_move_x): Same.
171 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
173 * gc.c (scm_init_storage): Skip registration of cleanup on systems
174 which lack atexit. (Is it important that cleanup is made
175 properly? Maybe we should replace all `exit' with `scm_exit' and
178 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
179 scm_struct_free_standard, scm_struct_free_entity): Declared to
180 return scm_sizet instead of size_t.
182 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
183 there on sunos4.1.4.)
185 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
187 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
188 Account for the case when second argument is unbound.
190 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
191 (Thanks to Karoly Lorentey.)
193 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
194 isn't present. (Thanks to Suzuki Toshiya.)
196 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
199 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
202 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
203 Bernard Urban and Ian Grant.)
205 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
206 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
207 change in the representation of entities and operators.)
209 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
211 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
212 don't allocate zero bytes (thanks to Bill Schottstaedt).
214 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
216 * procs.c (scm_setter): Converted to use generic dispatch.
218 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
221 * load.c (scm_search_path): Don't try extensions which already are
222 present at the end of the filename.
223 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
225 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
227 Cleanup and simplification of generic method dispatch.
228 Also, the quadruple representation of entity and operator
229 procedures has been replaced with single.
231 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
233 * print.c (scm_isymnames): Removed #@hash-dispatch.
235 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
236 from eval.c; Support 0 arity methods.
237 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
238 (scm_apply_generic_env): Removed.
239 Replaced slots proc0-3 with procedure.
241 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
242 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
243 SCM_OPERATOR_PROCEDURE.
244 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
245 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
247 * struct.c, struct.h: Replace 4 procedure slots with one.
248 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
250 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
253 * eval.c (scm_sym_args): Removed.
254 (SCM_CEVAL): Simplified entity application.
255 Moved dispatch code to objects.c.
257 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
259 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
261 * sort.c (closureless): Use scm_eval_body.
263 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
264 with a symbol as last form was first called normally and then via
265 `map' or some other mechanism using primitive apply, an ILOC was
268 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
270 This change extends the representation of primitive procedures
271 with more data fields, e.g. a place for documentation and true
272 procedure properties.
274 * procs.c, procs.h (scm_subr_entry): New type: Stores data
275 associated with subrs.
276 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
277 SCM_SUBR_DOC): New macros.
278 (scm_subr_table): New variable.
279 (scm_mark_subr_table): New function.
281 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
283 * gc.c (scm_gc_mark): Don't mark subr names here.
284 (scm_igc): Call scm_mark_subr_table.
287 This change implements a scheme for letting a generic work as a
288 shadow for a primitive procedure. If the primitive procedure
289 can't dispatch on its arguments, control is left over to the
290 generic. Normal wrong type arg errors will be generated until the
291 user has hung the first method on the primitive.
293 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
295 * procs.c, procs.h (scm_subr_p): New function (used internally).
297 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
299 * objects.c, objects.h (scm_primitive_generic): New class.
301 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
303 * print.c (scm_iprin1): Print primitive-generics.
305 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
306 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
308 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
309 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
310 primitives). NOTE: This means that it is now *required* to use
311 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
312 obscured representation that will be removed in the future anyway,
313 so backward compatibility is no problem here).
315 * numbers.c: Converted most numeric primitives (all but bit
316 comparison operations and bit operations) to dispatch on generic
320 Better support for applying generic functions.
322 * eval.c, eval.h (scm_eval_body): New function.
324 * objects.c (scm_call_generic_0, scm_call_generic_1,
325 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
329 Optimization of the generic function dispatch mechanism.
331 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
332 called scm_memoize_method instead of doing a second lookup.
334 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
339 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
340 scm_sysintern so that the binding connected with the subr name
341 isn't cleared when we give set = 0.
344 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
346 More transparent handling of ports with print states.
348 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
349 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
350 instead of a pair of a port and a print state. We'll need to cons
351 once extra in scm_printer_apply but the type system will be
352 cleaner, it will mix better with GOOPS, and, it will be even more
353 transparent to the user.
355 * print.c (scm_get_print_state): New procedure: Given an output
356 port, return the print state associated to it in the current print
357 chain, if one exists;
358 (scm_port_with_print_state): New procedure: Associate a
359 print-state with a port.
360 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
361 (scm_printer_apply): Wrap port and pstate as a smob;
362 (print_state_printer): Removed.
364 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
366 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
369 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
370 testing (otherwise the port-print-state trick won't be transparent
371 to the user; one example where this caused problems was in the
372 (ice-9 format) module).
374 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
376 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
377 SCM_UNSPECIFIED instead of the set value.
379 1999-08-20 James Blandy <jimb@mule.m17n.org>
381 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
383 * ports.h (enum scm_port_rw_active): New enum, containing
384 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
385 zero). The debugger knows about enums, but doesn't know about
387 (typedef scm_port): Declare rw_active member to be an enum
389 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
391 * ports.c (scm_add_to_port_table): Same.
392 * strports.c (st_flush, st_end_input): Same.
394 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
395 scm_must_realloc, and scm_done_malloc as appropriate.
397 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
399 * sort.c (quicksort): Added condition to protect the algorithm
400 from crashing the interpreter if the less predicate is buggy.
402 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
404 * fports.c (fport_write): fix line-buffering mode again.
405 (scm_open_file): recognise 'l' for line-buffering.
406 (scm_setvbuf): recognise _IOLBF for line-buffering.
408 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
410 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
413 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
416 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
418 * fports.c (fport_write): use memcpy instead of strncpy, in case
419 the data contains NUL.
421 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
423 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
425 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
426 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
427 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
428 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
429 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
430 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
431 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
432 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
433 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
434 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
435 scm_sym_ as prefix for symbols.
437 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
439 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
440 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
441 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
442 scm_sym_atcall_cc): Made global.
444 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
446 * eval.c (scm_sym_args): Made global.
448 * objects.c (scm_set_object_procedure_x): Disallow setting of
449 procedures for pure generic functions.
451 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
453 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
454 Scheme name from lseek to seek, but lseek was added recently so
455 it shouldn't be a big problem.
456 * ports.c, gdbint.c, ioext.c: changed callers.
458 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
460 * fports.c (fport_input_waiting): if select is used, return 1
461 instead of whatever FD_ISSET expands to. maybe it will be useful
462 to interpret the value from the input_waiting ptob procedure as a
463 lower bound on the number of bytes available.
465 * Mikael asked for a few names to be changed...
467 * ports.c (scm_make_port_type): take the write procedure as the
468 second argument instead of the flush procedure.
469 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
470 fflush -> flush, read_flush -> end_input, fclose -> close,
471 fill_buffer -> fill_input, ftruncate -> truncate,
472 input_waiting_p -> input_waiting.
474 * ports.c (end_input_void_port): was read_flush_void_port.
475 (scm_set_port_end_input): was scm_set_port_flush_input.
476 (scm_set_port_flush): was scm_set_port_write.
477 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
478 (scm_end_input): was scm_read_flush.
479 (scm_fill_input): was scm_fill_buffer.
480 (scm_flush): was scm_fflush.
481 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
482 (fport_end_input): was local_read_flush.
483 (fport_flush): was local_fflush.
484 (fport_close): was local_fclose.
485 (fport_truncate): was local_ftruncate.
486 (fport_seek): was local_seek.
487 (fport_free): was local_free.
488 (fport_fill_input): was fport_fill_buffer.
489 * strports.c (st_end_input): was st_read_flush.
490 (st_truncate): was st_ftruncate.
491 * vports.c: (sf_flush): was sfflush.
492 (sf_close): was sfclose.
493 (sf_fill_input): was sf_fill_buffer.
495 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
498 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
500 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
501 forms now contain the expressions to be dispatched upon instead of
502 depending on a surrounding lambda or let; Generic function
503 dispatch has been optimized; `apply' on a generic function now
504 works a little bit strangely. It uses a trick so that the type
505 dispatch code in SCM_CEVAL can be reused.
507 * objects.h, objects.c (scm_apply_generic_env): Added (used by
509 (scm_operator_p): Added.
510 (scm_sym_atdispatch): Added.
511 (scm_set_object_procedure_x): Modified to handle the new style
513 (scm_object_procedures): New debugging procedure.
515 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
517 * eval.c, eval.h (scm_sym_args): Added.
519 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
521 * feature.c, feature.h (scm_c_run_hook): Added.
523 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
524 cdrxnoap and loopnoap instead of begin and loop.
526 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
528 * ports.c (scm_putc, scm_puts),
529 * unif.c (scm_uniform_array_write): use scm_lfwrite.

535 SCM_IM_HASH_DISPATCH.
537 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
538 (scm_si_redfined, scm_si_hashsets): Moved.
540 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
541 flag which combines type and status info so that the class
542 redefinition protocol has zero cost during normal execution.
544 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
546 * ports.h (scm_ptob_descriptor): include a write procedure again.
547 it's more efficient for unbuffered fports (e.g., sockets.)

550 * vports.c (scm_make_sfptob): set write proc in ptob.
551 * strports.c (scm_make_stptob): set write proc in ptob.
552 * ports.c (write_void_port): new procedure.

559 * ports.c (scm_make_port_type): initialise ptob write procedure.
560 (scm_set_port_write): new proc.
562 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
564 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
565 until we've verified that it is actually a port. (Thanks to

570 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
571 code, particularly an unnecessary test (len != size, where len ==
572 size). (Was this leftovers from debugging code, or have I missed
575 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
576 size. (Thanks to James Dean Palmer.)
578 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
579 (Thanks to Lorentey Karoly.)
581 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
583 * eval.c (scm_m_expand_body): Use scm_cons_source.
585 * struct.c (scm_print_struct): Use vtable name.
587 * print.c (scm_init_print): Set name of print state type.
589 * stacks.c (scm_init_stacks): Set name of stack type.
591 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
593 * eval.c (SCM_CEVAL): Removed old implementation of internal
596 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
598 * debug.c, debug.h (scm_reverse_lookup): Added.
599 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
600 internal procedure definitions; Don't use scm_i_inner_name.
602 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
605 * eval.h: Added prototypes for multi language support functions.
607 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
608 improper lists in the low-level representation, since that will
609 cause a begin to be prepended at macro expansion.
611 * eval.c (scm_cons_source): Version of cons which copies source
612 properties from an existing cell.
613 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
615 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
616 procedure source before calling scm_unmemocopy instead of faking
619 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
621 Ported `internal defines' fix from SCM. Original ChangeLog entry:
623 1998-07-09 Radey Shouman <radey@colorage.com>
625 * eval.c (ceval_1): Modifications to allow rewriting of interal
626 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
627 body of which it is the CAR is macro expanded by m_expand_body,
628 which rewrites internal DEFINE.
630 (m_expand_body): Added.
632 (m_macroexp1): Added argument to control error checking:
633 m_expand_body may speculatively expand forms in the wrong
634 environments. Made argument number checks conditional on
637 (m_body): Added, error checks bodies and inserts the ISYM tokens.
639 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
642 (m_cond): (m_case): (m_quote): Modified to avoid destructively
643 changing their argument forms. Since m_expand_body
644 speculatively macro expands forms the process must be
647 (m_ident_eqp): Fixed to use proper environment.
649 (renamed_ident): Added DEFER_INTS_EGC.
651 Added prototypes for static functions.
657 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
658 is false, do not produce an error for unbound variables, return a
659 pointer to cell_undef instead.
661 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
665 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
666 destructively changing their argument forms. Since m_expand_body
667 speculatively macro expands forms the process must be reversible.
669 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
670 SCM_IM_LET introduced by named lets.
672 (scm_m_letstar): Use scm_m_body instead of bodycheck.
674 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
675 scm_letrec. scm_letrec1 does not check for a null binding and
676 takes an additional argument to specify the ISYM of the body. Use
677 scm_m_body instead of bodycheck.
679 (scm_m_let): Use scm_m_body instead of bodycheck.
681 (scm_m_expand_body, scm_macroexp): New.
683 (unmemocopy): Account for ISYMs introduced by scm_m_body.
685 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
686 check=1. Throw error for internal defined that have not been
687 rewritten by scm_m_expand_body.
689 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
690 Removed prototype for SCM_APPLY.
692 * tags.h: Added extern declaration of scm_isymnames.
694 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
696 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
698 * lang.c: New file: Beginning of multi-language support.
700 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
702 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
703 (scm_dynamic_wind): Added argument checking for the after guard so
704 that we don't add garbage on the dynwind chain.
705 (scm_swap_bindings): Added.
707 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
708 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
709 (scm_isymnames): New isyms for multi-language support.
711 * eval.c (scm_nil, scm_t): New symbols.
712 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
713 forms for multi-language support.
715 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
717 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
719 Renamed functions in the random function library interface
720 from scm_i_XXX --> scm_c_XXX.
722 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
724 * ports.c (scm_putc): fix line-buffering.
726 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
728 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
729 scm_set_ptob_XXX --> scm_set_port_XXX.
731 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
733 * ports.c, ports.h (scm_make_port_type): New interface for
734 creation of port types (replaces scm_newptob). Just as for the
735 smobs, we need to separate the internal representation of smob
736 types from the interface, so that we easily can add new fields and
737 rearrange things without caring about backward compatibility.
738 This change was forced by the need in GOOPS to create classes
739 representing port types.
740 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
741 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
742 scm_set_ptob_seek, scm_set_ptob_truncate,
743 scm_set_ptob_input_waiting_p): New setters.
744 (scm_newptob): Rewritten to use scm_make_port_type. For backward
746 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
747 (scm_prinport): Removed.
748 (scm_port_print): Added.
749 (scm_print_port_mode): Added.
750 (void_port_ptob, print_void_port, close_void_port, noop0):
751 Removed. Removed #include "genio.h" Added #include "objects.h",
754 * fports.c (prinfport): Moved code from ports.c.
756 (scm_fptob): Removed. Instead use new interface.
757 (scm_make_fptob): Added. (Need to create basic ports in a
758 specific order in ports.c.)
760 * strports.c (scm_stptob, prinstpt, noop0): Removed
761 (scm_make_stptob): Added.
763 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
764 (scm_make_sfport): Added.
766 * filesys.c (scm_dir_print): Don't use the port printing code.
767 Instead provide specific directory printer.
769 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
771 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
774 * smob.c (scm_smob_print): Handle non-existing type name nicely.
775 Removed #include "genio.h"
777 * objects.c (scm_make_port_classes): New function ptr.
779 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
781 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
783 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
784 allow the 1st argument to be a fdes or filename as well as a
785 port (as in the filesys.c version).
787 * filesys.c (scm_truncate_file): removed.
789 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
791 * readline.c, readline.h: Removed.
793 * objects.c, objects.h (scm_port_class): Added.
794 (scm_class_of): Look up port class in scm_port_class.
795 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
796 SCM_INOUT_PCLASS_INDEX): Added.
799 * Makefile.am: Removed genio.c, genio.x.
803 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
805 * init.c: Make sure that scm_post_boot_init_modules is called only
806 once. (Important when using a dumped image.; Thanks to Bernard
809 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
811 * guardians.c (scm_guardian_zombify): Separate scanning for
812 zombies from marking the pairs of the free list.
814 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
815 use the macros. (Thanks to Michael Livshin.)
817 * eval.c (scm_m_lambda): Let bodycheck check the body of the
818 lambda. Let your sins be purified by the blood of the lambda.
819 (Thanks to Eric Hanchrow.)
821 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
822 (Thanks to Valdis Kletnieks.)
824 Fixes for EMX from Mikael Ståldal.
826 * filesys.c: #include <io.h>, if we have it.
827 * scmconfig.h.in: Regenerated.
829 * stime.c (ftime): Delete declaration for this function --- let
830 the system supply it.
832 Cleanups from John Bley.
834 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
836 * gsubr.c: Don't include "gsubr.h" twice.
838 Cleanups for compilation on Irix 6, from David Kaelbling.
840 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
841 regex_t pointer. This is what the callers have, mostly.
842 (scm_regexp_exec): Don't forget to pass the `rx' argument to
843 scm_regexp_error_msg.
845 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
846 int. That way, if we get a warning on this line, it's more likely
847 that we're really missing bits we care about.
849 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
852 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
853 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
854 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
855 cast at all is more appropriate in every case. At the moment, we
856 assume everywhere that SCM is an integral type anyway.
858 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
860 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
861 read_pos after scm_fill_buffer.
863 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
866 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
867 fports.c (fport_fill_buffer): implement the interface change.
869 * ports.c (scm_fill_buffer): interface change: no longer increments
870 read_pos past the character that's returned. it seems clearer to
871 leave it to the caller to decide what to do (thanks Jim).
873 * vports.c (sf_fill_buffer): put the read char into the buffer
874 as well as returning it.
876 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

883 (st_seek): don't allow string to be extended if seeking past
884 the end of a read-only port.

888 * strports.c (st_seek): change the resize checks.
890 * ports.c (scm_ftruncate): throw error if offset works out negative.
892 * strports.c (st_flush): increase string size in blocks of
893 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
894 it's greater and reset read_buf_size.
895 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
896 to be maintained for output ports too (it holds the written
897 part of the string, while write_buf may have unwritten buffer
899 (st_truncate): rewritten.
900 (top of file): added a few notes.
902 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
904 Patch from Greg Badros:
905 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
906 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
907 (function pointer) argument to scm_make_gsubr and scm_make_subr
908 calls. This avoids warnings in C++ programs using guile-snarf.
910 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
912 * strports.c (st_grow_port): set pt->read_pos. set
913 pt->read_buf_size one less than pt->write_buf_size if there's
914 an unwritten char at the end of the string. similarly for
916 (st_resize_port): renamed from st_grow_port.
917 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
918 seek from read_end instead of write_end for SEEK_END.
919 (st_ftruncate): calculate current length using readbuf, not write
921 (scm_strport_to_string): use read_buf_size for length.

927 (scm_call_with_output_string, scm_strprint_obj): use
928 scm_strport_to_string.

931 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
933 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)

937 * smob.c: added scm_make_smob_type_mfpe (), scm_set_smob_mfpe ();
938 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
939 and "bigneg" smob types.
941 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
942 SCM_RETURN_NEWSMOB macro. Added protos for new functions in

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

1030 * dynl-dl.c (sysdep_dynl_link): Added parenthesis around the
1031 trinary conditional in order for the flag computation to be
1034 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1036 * struct.c, struct.h:
1038 In order to support different kinds of deallocation, a destructor
1039 slot has been added to struct vtables. This allows for structs
1040 containing pointers to other memory blocks.
1042 (scm_struct_i_free): New hidden struct slot. Holds destructor for
1043 instances to this vtable.
1044 (scm_struct_free_0): New destructor: Doesn't deallocate data.

1109 pointers. (Thanks to Mark Elbrecht.)
1111 1999-06-19 Jim Blandy <jimb@savonarola.red-bean.com>
1113 Patch from Greg Harvey:
1114 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1115 around the condition of an `if', `while', etc., even if the
1116 condition is a macro invocation that expands to something
1117 surrounded by parens. It's more readable.
1119 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1120 proper lists, and of the appropriate lengths.
1121 (check_map_args): New function. (Thanks to Greg Harvey for the
1124 1999-06-19 Michael Livshin <mike@olan.com>
1126 * guardians.c (guardian_t): `next' - new field to be used for
1127 chaining the live guardians in a single-linked list during the GC
1129 (GUARDIAN_NEXT): convenience macro to access the `next' field.
1130 (guardians, guardians_size, n_guardians): deleted.

1135 (scm_guardian_gc_init): zero the live guardian list.
1136 (scm_guardian_zombify): iterate through the live guardian list.
1138 (Applied by Jim Blandy.)
1140 1999-06-16 Jim Blandy <jimb@savonarola.red-bean.com>
1142 * gc.c (scm_mallocated): Just make this signed.
1143 (scm_igc): Check for underflow by seeing if this is negative.
1145 * gc.h (scm_mallocated): Fix declaration.
1146 (Thanks to Greg Harvey.)
1148 * ports.h: #include <sys/types.h>, to get a definition for `off_t'.

1152 * stime.c (bdtime2c): Initialize lt->gmtoff and lt->tm_zone from
1153 sbd_time. (Thanks to Eric Hanchrow.)
1155 Fix from Ken Raeburn <raeburn@raeburn.org>:
1156 * weaks.c (scm_make_weak_vector): Add another extra slot before
1157 vector contents, to be used only during garbage collection.
1158 * weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
1159 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
1161 (scm_weak_size, scm_n_weak): Deleted.
1162 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
1163 vectors without allocating new storage during GC, using
1164 scm_weak_vectors as the head of the chain.
1165 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1166 instead of stepping through an array.
1167 (scm_gc_sweep): Update offset used to find start of weak vector to
1169 (scm_init_storage): Set scm_weak_vectors to EOL.
1171 Fix from Ken Raeburn <raeburn@raeburn.org>:
1172 * gc.c (already_in_gc): New variable.
1173 (scm_igc): Set and clear already_in_gc; abort if it's set at
1176 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
1178 Fix from Gary Houston:
1179 * fports.c (local_seek): Signal an error if the seek fails.
1180 * ports.c (scm_lseek): Don't check return value of port's seek
1181 function; it's its job to signal an error if there's a problem.
1183 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
1185 * strports.c (scm_call_with_output_string): Don't include the
1186 extra character at the end of the string in the result.
1188 * ioext.c (scm_read_line): Switch to reading properly.
1190 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
1191 scmsigs.c, strports.c, vports.c: Install the sources which
1192 actually correspond to the changes described below. I got the
1193 ChangeLog entries and the patch from two different places...
1195 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1197 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1198 it shows up as terrible performance, as we GC constantly.
1200 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1201 newline. A bit faster, and definitely hairier.
1202 (scm_read_line): Count newlines here instead.
1204 * strings.c (scm_take_str): New function.
1205 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1206 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
1207 scm_take_str, to avoid copying the string.
1209 Add some simple-minded support for line buffered ports.
1210 * ports.h (SCM_BUFLINE): New flag for ports.
1211 * init.c (scm_init_standard_ports): Request line-buffering on
1212 the standard output port.
1213 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1215 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1216 and there's a newline to be written, flush the port.
1218 Gary Houston's open-buffer port patches:
1220 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1222 * ports.c: (scm_lseek): clear buffers even if just reading current
1225 * fports.c (local_fclose): call local_fflush unconditionally.

1228 1999-04-25 Gary Houston <ghouston@easynet.co.uk>
1230 * ports.h (scm_port): make read_pos a pointer to const.
1231 strports.c: take care of rw_active and rw_randow.
1232 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
1233 strports.c (scm_mkstrport): check that pos is reasonable.
1234 ioext.c (scm_ftell, scm_fseek): use lseek.
1235 (SCM_CLEAR_BUFFERS): macro deleted.
1236 ioext.c (redirect_port: use ptob fflush, read_flush.
1237 ports.h (scm_ptobfuns): add ftruncate.
1238 ports.c (scm_newptob): set ftruncate.
1240 ports.c (scm_ftruncate): new procedure.
1241 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
1242 strports.c (st_seek, st_grow_port): new procs.
1243 fports.h (scm_port): change size types from int to off_t.
1244 ports.c (scm_init_ports): initialise the seek symbols here
1245 instead of in ioext.c.
1246 strports.c (scm_call_with_output_string): start with an empty
1247 string, so seek and ftruncate can be used.
1249 gdbint.c: adjust string port usage.
1251 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1253 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1254 equivalent to fflush for the read buffer.
1255 * ports.c (scm_newptob): set read_flush.
1256 ports.c (void_port_ptob): set read_flush.
1257 fports.c (local_read_flush): new proc. add to ptob.
1258 strport.c (st_read_flush): likewise.
1259 vport.c (sf_read_flush): likewise.
1260 fports.h (struct scm_fport): remove random member. there's nothing
1261 left but fdes. leaving it as a struct to allow for future changes.
1262 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1263 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1264 ptob proc if the read buffer is filled.
1266 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1268 * ports.h (scm_port): add a rw_random member and replace
1269 reading and writing members with rw_active member.
1270 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1272 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1274 * ports.h (struct scm_port_table): add writing and reading members
1275 to replace write_needs_seek: it isn't good enough for non-fports.
1276 ports.c, ioext.c, fports.c: corresponding changes.
1277 (struct scm_port_table): give it a typedef and rename to scm_port.
1278 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1279 corresponding changes.
1281 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
1283 * ports.c (scm_newptob): bugfix: set seek member.
1284 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
1285 and generalised to all port types.
1287 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
1289 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1290 signals (it was only being done for handlers installed from Scheme).
1291 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1292 waiting for input caused an EINTR error from read.
1294 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1296 * ports.h (struct scm_port_table): make all the char members
1297 unsigned, so they convert to int without becoming negative if large.
1299 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1301 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1302 with threads enabled. rename this procedure to
1303 fport_wait_for_input and take a port instead of a fdes.
1304 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1306 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1307 get readline support working again: use fdopen to get FILE objects.
1309 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1311 * gc.c (scm_init_storage): install an atexit proc to flush the
1313 (cleanup): the new proc. it sets a global variable which can be
1314 checked by the ptob flush procs to avoid trying to throw
1315 exceptions during exit. not very pleasant but it seems more reliable.
1316 * fports.c (local_fflush): check terminating variable and if set
1317 don't throw exception.
1318 * CHECKME: that the atexit proc is installed if unexec used.
1320 * throw.c (scm_handle_by_message): don't flush all ports here.
1321 it still causes bus errors.
1323 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1324 and move to ioext.c.
1326 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1328 * ports.c (scm_char_ready_p): check the port buffer and call the
1329 ptob entry if needed.
1331 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1332 ptob initialisers. use it in char-ready
1334 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1336 * vports.c (sfflush): modified to write a char (since softports
1337 currently use shortbuf.)
1339 * fports.c (scm_standard_stream_to_port): moved to init.c and
1342 * init.c (scm_init_standard_ports): make stdout and stderr
1343 unbuffered if connected to a terminal. with stdio they
1344 were line-buffered by default.
1346 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1349 * ports.h (scm_ptobfuns): change fflush return to void.
1350 change flush proc definitions.
1352 * strports.c (scm_call_with_output_string): get size from
1353 buffer instead of port stream.
1354 (st_flush): new proc.
1356 * ports.h (struct scm_port_table): added write_end member,
1357 as an optimisation. set it where write_buf_size is set.
1359 * ports.h (struct scm_port_table): change stream from void *
1360 back to SCM. SCM presumably must be large enough to hold a
1361 pointer (and probably vice versa but who knows.)
1362 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1364 (scm_puts): rewritten
1365 * fports.c (local_ffwrite, local_fputs): removed.
1366 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)
1367 * vports.c (sfputc, sfputs, sfwrite) likewise.
1368 * ports.c (write_void_port, puts_void_port): removed.
1369 (putc_void_port, getc_void_port, fgets_void_port): likewise.
1371 * ports.c (scm_lfwrite): rewritten using fport.c version.
1373 * fports.c (local_fputc): deleted.
1375 * ports.c (scm_add_to_port_table): initialise write_needs_seek.
1377 * ports.h (scm_ptobfuns): add seek function pointer.
1378 * fports.c: set it to local_seek, new procedure.
1381 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1382 use ptob for seek. take ptob instead of fport arg.
1384 * ports.h (struct scm_port_table): new member write_needs_seek,
1385 replaces reading member in fport struct.
1387 * vports.c (sfgetc): store the getted char into the buffer.
1388 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1389 the Scheme interface is still a procedure that gets a char.
1390 (scm_make_soft_port): set up the port buffer (shortbuf).
1392 * fports.c (local_fgetc, local_fgets): deleted.
1393 * strports.c (stgetc): likewise.
1394 * ports.c: scm_generic_fgets: likewise.
1396 * ports.h (scm_ptobfuns): add fill_buffer.
1397 * ports.c (scm_newptob): assign it.
1398 * strports.c (scm_mkstrport): set up the buffer.
1399 put just the string into the stream, not cons (pos stream).
1400 (stfill_buffer): new proc.
1402 * ports.h: fport buffer moved into port table: to be
1403 used for all port types.

1412 scm_getpeername, scm_recv, scm_send, scm_recvfrom,
1414 use SCM_FPORT_FDES. use SCM_OPFPORTP not SCM_FPORTP.
1416 * posix.c (scm_getgroups): use SCM_ALLOW/DEFER_INTS.
1417 (scm_ttyname): use SCM_FPORT_FDES.

1425 (scm_fdopen): use scm_fdes_to_port.
1427 * ports.c (scm_init_ports): don't try to flush ports using
1428 atexit(). it's too late, errors will cause SEGV.

1432 * fports.h (SCM_FDES_RANDOM_P): new macro. use it in
1433 scm_fdes_to_port and scm_redirect_port.

1448 * gdbint.c: likewise.
1449 * ports.h (SCM_SSTREAM): new macro.
1451 * fports.c (scm_input_waiting_p): use scm_return_first, since port

1474 ports.c fports.c ioext.c posix.c socket.c net_db.c filesys.c:
1475 removed all uses of SCM_DEFER/ALLOW ints for now. they were mainly
1476 just protecting errno. some may need to be put back.
1478 * scmsigs.c (take_signal): save and restore errno while this
1481 *fports.c (print_pipe_port, local_pclose, scm_pipob): deleted.

1596 1999-05-09 Jim Blandy <jimb@savonarola.red-bean.com>
1598 * strop.c (scm_string_capitalize_x): Use the SCM object `s' in
1599 error messages, not the uninitialized string `str'. Love that
1602 * strop.c (scm_substring_move_x): New function, which can handle
1603 arbitrary overlapping substrings.

1680 * numbers.c (isfinite): Define this macro if not defined: Return a
1681 non-zero value if X is finite. (From ISO C 9x standard.)

1723 * error.c (scm_wta): Pass SCM_LIST1 (arg) instead of SCM_EOL to
1724 scm_misc_error when pos is a string. This allows for dispatching

1734 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1736 Most of this batch of changes is about how to deal with extended
1737 types when an object system is loaded into Guile. A nice object
1738 system is capable of representing Guile's types as class objects.
1740 For example, we want a regular expression to be of class <regex>.
1741 But regular expressions are smobs which aren't under direct
1742 control of the object system, so there has to be some mechanism
1743 which informs the object system that a new class should be created
1744 which can represent the smob type. I call this a "wrapper class".
1746 * objects.c: #include "smob.h";
1747 (scm_class_keyword): Removed. (Class is automatically created by
1749 (scm_smob_class): Array of smob classes indexed by smobnum.
1750 (scm_make_extended_class): "Plugin" function pointer for creation
1751 of wrapper classes for smob and struct types.
1752 (scm_class_of): Handle compiled closures. (Currently regarded as
1754 Use scm_smob_class to handle smob types;
1755 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1756 through scm_smob_class;
1759 * smob.c (scm_newsmob): Also create a wrapper class if
1760 scm_smob_class has been initialized.
1762 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1763 type code and smobnum.
1765 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1766 (scm_struct_table): Weak key table with auxilliary information for
1767 struct types. Currently used for names and wrapper classes.
1768 (scm_struct_ihashq): Hash function for structs.
1769 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1770 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1771 for accessing names of vtables. The record implementation in
1772 boot-9.scm currently uses the setter to record the name of record
1773 types. When the object system is initialized, it can use this
1774 information to create wrapper classes with suitable names.
1775 (scm_init_struct): Allocate scm_struct_table.
1776 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1777 (struct tags are a finite resource and we might want to restrict
1778 the use of tags to vtables only. E.g., Goops only uses tags for
1780 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1782 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1785 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1786 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1787 Used for access of struct table entries.
1789 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1790 (scm_hash_fold): New procedure. Used to process all entries in a
1791 hash table (in no particular order).
1793 Argh! For the umpteenth time I got compilation errors because of
1794 the "intuitive" name `kw'. This has to have an end:
1796 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1797 "kw" --> "keywords" everywhere.
1798 (I doubt that this will cause big compatibility problems since the
1799 application interface is unaffected.)
1801 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1803 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1805 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1806 column inums to native form.
1808 Improvement of backtraces: Introduces a new stack narrowing
1809 specifier, #t, for the inner cut. (See further in the comments in
1810 stacks.c:narrow_stack ().)
1812 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
1813 (Used to flag certain system procedures which shouldn't turn up in
1816 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1817 modules which aren't "user" modules and the code of which
1818 shouldn't turn up in backtraces.)

1821 Extract the lookup closure from an environment.
1822 (scm_system_module_env_p): New function: Return non-#f if MODULE
1825 * stacks.c: #include "eval.h"; #include "procprop.h";
1826 (narrow_stack): Handle new narrowing specifier #t.
1828 * debug.c (scm_procedure_name): Use name property in the default
1831 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1833 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1835 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1836 procedure throughout.
1838 * print.c (scm_iprin1): Removed extraneous space when printing
1839 procedure-with-setters.
1841 Entity and operator setter slots were introduced as a complement
1842 to the <procedure-with-setter> type in order to support entities
1843 and operators with setters in a reasonable and efficient way.
1844 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1847 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1857 1999-03-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1859 * objects.h (SCM_OBJ_CLASS_REDEF): New macro: Find class slots
1860 directly through the instance.
1862 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1864 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1865 scm_struct_i_flags instead of scm_vtable_index_layout!
1867 * list.c (scm_list_star): New procedure.
1869 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1950 SYMB now point to const.
1952 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1954 * print.c (scm_iprin1): Use scm_procedure_name instead of
1955 scm_procedure_property for compiled closures.
1957 * tags.h (scm_tc7_pws): New procedure type. Four representations
1958 for procedure-with-setters were considered before selecting this
1961 1. A closure where the CODE and ENV slots are used to represent
1962 the getter and a new SETTER slot is used for the setter. The
1963 original getter is stored as a `getter' procedure property. For
1964 closure getters, the CODE and ENV slots contains a copy of the
1965 getter's CODE and ENV slots. For subr getters, the CODE contains
1968 2. A compiled closure with a call to the getter in the cclo
1969 procedure. The getter and setter are stored in slots 1 and 2.
1971 3. An entity (i.e. a struct with an associated procedure) with a
1972 call to the getter in the entity procedure and the setter stored
1973 in slot 0. The original getter is stored in slot 1.
1975 4. A new primitive procedure type supported in the evaluator. The
1976 getter and setter are stored in a GETTER and SETTER slot. A call
1977 to this procedure type results in a retrieval of the getter and a
1978 jump back to the correct eval dispatcher.
1980 Representation 4 was selected because of efficiency and
1983 Rep 1 has the advantage that there is zero penalty for closure
1984 getters, but primitive getters will get considerable overhead
1985 because the procedure-with-getter will be a closure which calls
1988 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1989 <procedure-with-setter>, but together with rep 2 it suffers from a
1990 three level dispatch for non-GOOPS getters:
1992 cclo/struct --> dispatch proc --> getter
1994 This is because the dispatch procedure must take an extra initial
1995 argument (cclo for rep 2, struct for rep 3).
1997 Rep 4 has the single disadvantage that it uses up one tc7 type
1998 code, but the plan for uniform vectors will very likely free tc7
1999 codes, so this is probably no big problem. Also note that the
2000 GETTER and SETTER slots can live directly on the heap, using the
2001 new four-word cells.
2003 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

2073 (scm_merge_list_step): Bugfix: Don't presume that arguments in a C
2074 function call are executed in a well defined order.
2076 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2078 * alloca.c (alloca): Cast value returned by malloc. (Thanks to
2081 1999-01-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2083 * random.c: Removed alloca includes.
2085 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2087 * Makefile.in: This changed, for some reason I don't really
2088 understand, when I ran automake in the top level directory. This
2089 may be contamination by Cygnus internal releases. If you re-run
2090 automake and this change gets reverted, don't worry about it.
2092 1999-01-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2094 * sort.c, sort.h: New files: Implement slib's and scsh's sort

2108 Interface same as slib's.
2110 * Makefile.am: Added random.c, random.h, random.x.
2112 * init.c: #include "random.h";

2115 1998-12-23 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2117 * Makefile.am: New files: guardians.c, guardians.x, guardians.h
2119 * guardians.c, guardians.h (scm_make_guardian,
2120 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
2121 scm_get_one_zombie, scm_init_guardian): This is an implementation
2122 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
2123 David Eby (1993) "Guardians in a Generation-Based Garbage
2124 Collector" ACM SIGPLAN Conference on Programming Language Design
2125 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
2126 /pub/scheme-repository/doc/pubs/guardians.ps.gz
2127 Author: Michael N. Livshin.
2129 * gc.h (SCM_MARKEDP, SCM_NMARKEDP): New macros.
2131 * gc.c (scm_igc): Call scm_guardian_gc_init and
2132 scm_guardian_zombify.
2134 * init.c (scm_boot_guile_1): Call scm_init_guardian.
2136 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2138 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
2141 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2143 Move the procedure slots of entities to invisible slots (so that
2144 we can have operator class objects which themselves are entities).
2145 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
2146 SCM_STRUCTF_ENTITY): New constants.
2148 * struct.c (scm_make_struct): Allocate "invisible" room for
2149 procedures if SCM_STRUCTF_ENTITY is set in vtable.
2151 * gc.c (scm_gc_mark): Mark entity procedures.
2153 * struct.c, struct.h (scm_alloc_struct): Renamed from alloc_struct

2158 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
2159 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
2161 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
2163 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
2164 of syntactic forms, similar to SCM_PROC.
2165 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
2166 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
2167 for the name symbols when needed.
2169 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
2171 * Makefile.in: Regenerated.
2173 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
2175 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
2176 take the address of _into; it might be a register. Just have
2177 scm_debug_newcell return the new cell.
2178 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2179 taking the address of a place to store it as an argument.
2180 * gc.h (scm_debug_newcell): Change declaration.
2181 (Thanks to Greg Harvey.)
2183 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2185 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
2186 Replaces old names serial-array-copy! and serial-array-map!.
2188 * evalext.c (map-in-order): New name. Replaces serial-map.
2190 1998-12-05 Jim Blandy <jimb@totoro.red-bean.com>
2192 * smob.c (freeprint): New function.
2193 (freecell): Use it to print freed objects, for slightly easier
2196 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2198 * backtrace.c (display_frame): Made more robust. Doesn't throw an
2199 error if no source properties can be found for a frame. (Thanks
2200 to Christian Lynbech.)
2202 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2204 * objects.h: Removed slots direct_supers and direct_slots from the
2205 definitions of the rudimentary classes described by objects.h.
2207 * objects.c, objects.h (scm_entity_p): New procedure. Together
2208 with the predicates scm_procedure_p and scm_struct_p, this
2209 predicate makes it possible to differ between structs, entities
2212 * modules.c, modules.h (scm_resolve_module): New function.
2214 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2216 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2217 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2220 * objects.c (scm_entity_p): New procedure.
2222 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
2223 for asubrs, rpsubrs, lsubrs and lsubr_2s.
2225 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2227 * procprop.h (scm_i_procedure_arity): Added declaration.
2229 * procprop.c (scm_i_procedure_arity): Made global; New code to
2230 handle operators and entities.
2231 (scm_procedure_property): No need to call scm_procedure_p since
2232 scm_i_procedure_arity now does all necessary type checking.
2233 Added #include "objects.h".
2235 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2236 s_add_hook_x --> s_remove_hook_x.
2237 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
2238 Added #include "procprop.h"
2240 * feature.c, feature.h (scm_reset_hook_x): New procedure.
2241 (scm_make_hook): Optional argument defines number of arguments to
2243 (scm_make_named_hook): Take number of args as second arg.
2244 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2245 boot-9.scm for a while); First arg is the hook. The rest are
2246 arguments passed on to the hook procedures.
2248 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2250 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2251 scm_logbit_p): Do the computation in ulongs. This is not as nice
2252 as doing it in bignums, but at least it's good enough for
2253 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2255 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2256 subexpressions. (Thanks to Charbel Jacquin.)
2258 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2260 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2261 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2262 (scm_make_named_hook): New function.
2264 * feature.c: Added #include "eval.h".
2266 * modules.c (scm_make_module): Beautify the module.
2268 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2270 * modules.c, modules.h: New files: C interface to modules. (This
2271 is necessary in order to interface the object system to Guile
2272 properly. The guts of these modules will be replaced by the new
2273 module system in the future.)
2275 * init.c: Added #include "modules.h"
2276 (scm_boot_guile_1): Call scm_init_modules.
2277 (invoke_main_func): Call scm_post_boot_init_modules.
2279 * Makefile.am: Added modules.c, modules.x, modules.h.
2281 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2283 * procs.c: #include "objects.h"
2284 (scm_procedure_p): Return #t also on structs which are operators.
2286 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2287 <operator-metaclass> and <entity-class> to <standard-class>,
2288 <operator-class> and <entity> in order to conform with STKlos
2291 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2292 which isn't an operator.
2293 (SCM_APPLY): Ditto, but jump to badproc.
2295 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2297 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2298 Previously, structs implanted in code were interpreted as forms
2299 the operator of which was a gloc. We solve this by checking for
2300 the zero in the emulated vcell in the struct vtable. Since
2301 implanted structs always will look like forms with a gloc
2302 operator, execution will only be slowed down by maximally one
2303 extra test-and-branch per application.
2305 * evalext.c (scm_definedp): Removed check for isyms; Added a
2306 second optional argument: It is now possible to supply an
2307 evaluation environment in which to look for the symbol.
2309 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2311 * readline.c (scm_init_readline): Set
2312 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2314 * coop.c (coop_condition_variable_wait): Removed
2315 (coop_condition_variable_wait_mutex): Folded logic of
2316 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2317 prevent condvar signal lossage. Previously, another thread could
2318 start to run after unlocking the mutex but before putting the
2319 current thread on the wait queue. If that thread then would
2320 signal the first, the signal would be lost. (Thanks to Christian
2323 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2325 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2328 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2330 * objects.c (scm_i_make_class_object): Renamed from
2331 make_class_object; exported; error checking moved to
2332 scm_make_class_object and scm_make_subclass_object.
2333 (scm_make_class_object, scm_make_subclass_object): Use
2334 scm_i_make_class_object.
2335 (scm_make_subclass_object): Let the subclass have same metaclass
2338 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2340 * debug.c (scm_debug_options): Bugfix: Set the value of
2341 scm_stack_checking_enabled_p after setting debug options;
2342 #include "stackchk.h". (Thanks to Richard Polton.)
2344 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2346 * unif.c (scm_array_contents): removed unnecessary test for 0
2349 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2351 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2352 Replaced by macro `collect' in boot-9.scm.
2354 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2356 * eval.c (scm_copy_tree): Copy source properties if existent.
2358 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2359 don't, we may end up passing memoized source to a transformer.)
2361 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2363 * stack.c (get_applybody): Help function which lookups the first
2364 body form of the apply closure.
2365 (read_frames): Prevent the source of the first form of the apply
2366 closure from being recorded. This would only be confusing.
2368 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2369 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2371 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2373 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2375 (read_frames): Use SCM_MACROEXPP.
2377 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2379 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2380 don't contain interesting information since all arguments are
2381 present in the frame which applies the compiled closure anyway.);
2382 Skip the transformer application frames.
2384 * print.c (scm_iprin1): Print gsubrs as primitives.
2386 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2388 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2390 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2391 that we can identify these in a backtrace. (This change doesn't
2392 introduce any significant speed penalty.)
2394 * eval.c: Added note about `serial-map' using scm_map.
2396 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2397 readline options. They should reside in their own options array.
2399 * readline.c, readline.h (scm_readline_options,
2400 scm_readline_opts): Moved readline options here.
2402 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2404 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2405 SCM_ROCHARS instead of SCM_CHARS.
2407 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2408 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2410 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2412 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2413 This is quite important since the latter clears the
2414 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2415 every single character read...
2417 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2419 * print.c (scm_iprin1): Removed suspect looking (and indeed
2420 malevolent) semicolon after test for user supplied closure print
2421 procedure. (Thanks to Telford Tendys.)
2423 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2424 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2425 starting to search the list. Removed call to sloppy_mem_check.
2427 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2428 procedures: Same as scm_delq_x et al, but delete maximally one
2431 * options.c (scm_options, scm_init_options): GC-protect option
2432 values of type SCM. (Thanks to Telford Tendys.)
2434 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2436 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2437 make sure that there always is a "real" scm_lookupcar.
2439 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2441 * read.c, read.h (scm_read_opts): New read options
2442 "history-length" and "history-file".
2443 (scm_read_options): Stifle history to history length.
2445 * readline.c (scm_read_history, scm_write_history): New procedures.
2447 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2449 * eval.h (scm_macro_eval_x): Removed declaration.
2451 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2452 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2453 Renamed and made global.
2455 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2456 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2458 * evalext.c, evalext.h: New files. Contain non-R5RS things
2459 having to do with evaluation.
2461 * evalext.c (scm_serial_map): New procedure: Version of `map'
2462 which guarantees that the procedure is applied to the lists in
2464 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2465 returns a list of the results of the body forms instead of the
2466 result of the last body form.
2467 (scm_definedp, scm_m_undefine): Moved from eval.c
2469 * evalext.h (scm_m_sequence_to_list): Added declaration.
2471 * macros.c, macros.h: New files.
2472 (scm_procedure_to_syntax, scm_procedure_to_macro,
2473 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2474 scm_macro_name, scm_macro_transformer): Moved from eval.c
2475 (scm_make_synt): Moved from eval.c
2477 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2479 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2482 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2484 * debug.c, print.c: Added #include "macros.h".
2486 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2488 This change adds the ability to use `unread-char' multiple times
2489 without interspersed reads and adds the new procedure
2490 `unread-string'. The change is optimized for the common case of
2491 unreading a single character. This is also the reason behind the
2492 choice to store characters in the port itself: in most cases no
2493 extra malloc is required.
2495 The amount of code in some macros in ports.h has been increased to
2496 the extent that they would fit better as C functions, but, since
2497 this code belongs to the port representation, such functions
2498 should be placed in ports.c which would cause calls back and forth
2499 between ports.c and genio.c. That is not good for performance.
2500 Also, keeping them as macros allows the compiler to do some
2501 optimizations which are needed to make the current interface
2502 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2504 One benchmark (Guile startup time) indicates an increase of
2505 loading speed of 1%. Another (reading (using `read') boot-9.scm
2506 10 times) shows no change in performance.
2508 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2509 made to find a beautiful solution.)
2511 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2512 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2513 character. (SCM_CLRDY clears all.)
2514 (SCM_N_READY_CHARS): New macro: Returns number of unread
2515 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2516 (struct scm_port_table): New fields: `entry' contains port table
2517 index, `cp' points to last unread char, `cbuf' is the buffer for
2518 unread chars, `cbufend' points after end of the character buffer.
2520 * ports.h, ports.c (scm_unread_string): New procedure.
2521 (scm_grow_port_cbuf): New function.
2523 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2525 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2526 to read unread characters. Use SCM_TRY_CLRDY instead of
2529 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2531 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2533 * genio.c, genio.h (scm_ungets): New function.
2535 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2538 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2540 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2541 declarations. (Thanks to Russ McManus.)
2543 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2545 * numbers.c (num2long): As a software archeologist, I'm proud of
2546 this finding! :) Preliminary dating suggests an almost 4 year old
2547 remnant from the SCM ancestor. The sample has been removed from
2548 the finding site and is now safely stored in the repository.
2550 * numbers.h: Removed prototype for num2long.
2552 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2554 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2555 array as second arg.
2556 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2557 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2558 * gh.h: Updated and added prototypes.
2560 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2562 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2564 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2566 * guile-snarf.in: Never generate an empty file. (Thanks to
2569 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2570 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2571 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2572 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2573 gh_new_procedure5_0): Specify argument types, to appease C++
2574 compilers. (Thanks to Brad Bowman.)
2576 Bug reports from Russ McManus:
2577 * guile-snarf.in: If the CPP environment variable is set, use that
2578 as the C preprocessor, instead of the preprocessor autoconf
2580 * snarf.h (SCM_PROC): Cast the function pointer passed to
2581 scm_make_gsubr, to satisfy C++.
2583 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2584 Use the handler passed, instead of ignoring it and using
2585 gh_standard_handler. (Thanks to Etienne Bernard.)
2587 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2589 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2592 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

2609 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2612 * script.c (scm_compile_shell_switches): Define
2613 use-emacs-interface in the root module, so the repl code can see
2614 it. See today's change to top-repl in ice-9/boot-9.scm.
2616 * filesys.c (set_element, get_element): Make sure that `element'
2617 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2618 Boekemeier and Jorgen "forcer" Schaefer.)
2620 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2622 * chars.c (scm_charnames): In ASCII character name table, make
2623 newlines print as #\newline by default, not #\nl.
2625 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2626 alphabetical order. Oh thrills. But it helps me know how far
2627 along in the compilation I am.
2628 * Makefile.in: Regenerated.
2630 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2632 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2633 #bytes(...) to #y(...), and syntax for short vectors from
2634 #short(...) to #h(...). This may seem nutty, but, like the other
2635 uniform vectors, byte vectors and short vectors want to have the
2636 same print and read syntax (and, more basic, want to have read
2637 syntax!). Changing the read syntax to use multiple characters
2638 after the hash sign breaks with the conventions used in R5RS and
2639 the conventions used for the other uniform vectors. It also
2640 introduces complexity in the current reader, both on the C and
2641 Scheme levels. (The Right solution is probably to change the
2642 syntax and prototypes for uniform vectors entirely.)
2644 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2646 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2647 (Thanks to Jorgen "forcer" Schaefer.)
2648 * ports.h (SCM_NOFTELL): New flag.
2649 * fports.c (local_fgets): If it's set, use the generic fgets.
2650 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2652 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2654 * script.c (scm_compile_shell_switches): Add handling of -q switch
2655 (inhibit loading of user init file).
2656 (scm_shell_usage): Add usage text for -q switch.
2657 (scm_compile_shell_switches): Always load user init file first if
2658 it is loaded at all.
2660 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2662 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2663 and is now broken under NetBSD. I can't fathom what it's trying
2664 to do, so I've replaced it with something that I do understand,
2665 which seems to work, and which isn't broken on NetBSD. "Progress?
2666 You Decide." (Thanks to Perry Metzger.)
2668 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2669 signed/unsigned comparison.
2671 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2673 Warning fixes from Greg Harvey:
2674 * unif.c (scm_array_set_x): initializer for pos
2675 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2676 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2677 initializers for field_type, since EGCS so desparately wants to
2679 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2680 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2681 when GUILE_DEBUG is defined.
2682 * dynwind.h (scm_wind_chain): Same.
2683 * ports.h (scm_pt_size, scm_pt_member): Same.
2684 * print.h (scm_current_pstate): Same.
2685 * procs.h (scm_make_cclo): Same.
2687 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2689 Handle short and long long uniform arrays properly. (Thanks to
2691 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2692 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2693 scm_tc7_llvect (long long vectors).
2695 Change the way libguile and boot-9.scm are timestamped, to try to
2696 get rid of these spurious mismatch warnings. Now both
2697 libguile/versiondat.h and ice-9/version.scm are generated directly
2698 by the configuration process, rather than having version.scm
2699 generated directly, and libguile/versiondat.h generated by the
2700 Makefile, which is generated by configure. It seems that
2701 sometimes the Makefile would change, but versiondat.h depends on
2702 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2703 * Makefile.am (versiondat.h): Target removed; this is generated
2704 directly by the configure script now.
2705 (BUILT_SOURCES): Remove versiondat.h.
2706 * versiondat.h.in: New file, transformed by the configure script
2708 * Makefile.in: Regenerated.
2710 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2711 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2712 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2713 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2714 if we want to use them in a header file some day, we can. (Thanks
2715 to Michael Livshin.)
2717 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2718 SCM numbers, so we won't have rollover problems; the range of a
2719 signed long in milliseconds is about 25 days. (Thanks to Karl
2722 Don't redefine sleep and usleep; fix this problem now.
2723 * coop.c (sleep, usleep): Remove declarations; we don't use or
2724 redefine these any more.
2725 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2726 job of usleep and sleep in a thread-friendly way. We can use
2727 these in the rest of Guile. Define versions for systems both with
2728 and without iselect.
2729 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2730 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2731 we're just using it, not redefining it, we can use a K&R style
2733 (sleep): Declare this, too, if the system hasn't.
2734 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2735 scm_uthread_sleep if they're available; otherwise, just call the
2737 * scmconfig.h.in: Regenerated.
2739 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2741 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2743 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2745 * threads.c: Doc fix.
2747 The argument type of usleep varies from system to system,
2748 as does the return type. We really shouldn't be redefining usleep
2749 at all, but I don't have time to clean that up before the 1.3.
2750 release. It's on the schedule for afterwards. (Thanks to Julian
2752 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2754 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2755 * scmconfig.h: Regenerated.
2757 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2758 right way to handle system variation. Autoconf's approach is the
2760 * simpos.h (scm_software_type): Declaration deleted.
2762 * script.c (scm_find_executable): Don't test if unix is #defined
2763 here; first, NetBSD doesn't #define it, and second, it's the wrong
2764 way to go about these things. (Thanks to Perry Metzger.)
2765 (dld_find_executable): Delete this MSDOS support code. This isn't
2766 the way we want to support this; it needs to be rethunk at a
2769 * genio.c (scm_do_read_line): Don't just politely check that the
2770 line was either non-empty or EOF. Abort if it's empty and not
2773 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2775 * scmconfig.h.in: Regenerated.
2777 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2780 * genio.c (scm_do_read_line): Count lines correctly when the file
2781 doesn't end in a newline.
2783 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2785 * genio.c (scm_do_read_line): Maintain the line count correctly.
2786 (Thanks to Harvey J. Stein and Greg Harvey.)
2788 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2791 * numbers.c (big2str): Protect t from garbage collection until
2792 we're done. (Thanks to Gary Houston.)
2794 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2796 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2798 * Makefile.in: Regenerated.
2800 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2801 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2804 Do magic to mix reads and writes on stdio FILE-based ports.
2805 (Thanks to Christian Lynbech.)
2806 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2808 (pre_read, pre_write): New functions.
2809 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2810 local_fputs): Call them.
2811 (local_fflush): Mark the port as ready for reading and writing.
2812 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2813 flags on new port objects. This might not be accurate --- who
2814 knows what state the FILE * is in when we get it --- but it won't
2815 do extraneous calls to fflush or fseek, so it's no worse than the
2816 behavior before this change.
2817 * ports.h: Add comment.
2819 Centralize the creation of port objects based on stdio FILE * in
2820 fports.c; don't just throw them together anywhere.
2821 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2822 what the rest of Guile wants. Don't set the revealed count;
2823 that's only appropriate for stdin, stdout, stderr.
2824 (scm_standard_stream_to_port): This function does set the revealed
2826 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2827 not scm_stdio_to_port.
2828 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2829 * fports.c (scm_open_file): Same.
2830 * posix.c (scm_pipe): Same.
2831 * socket.c (scm_sock_fd_to_port): Same.
2832 * ioext.c (scm_fdopen): Same.
2833 (scm_freopen): Moved from here to...
2834 * fports.c (scm_freopen): ... here. This is really something that
2835 munges the internals of an fport, so it should go here.
2836 * fports.h (scm_stdio_to_port): Adjust prototype.
2837 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2838 * ioext.h (scm_freopen): Prototype removed.
2840 * filesys.c (set_element, get_element): This can work on both pipe
2841 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2844 * scmconfig.h.in: Regenerated.
2846 Change the definition of the functions in scm_ptobfuns so that
2847 they get passed the port object, not the port's stream.
2848 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2849 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2850 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2851 Pass the port itself to the scm_ptobs function.
2852 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2853 scm_generic_fgets): Same.
2854 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2855 getc_void_port, fgets_void_port, close_void_port): Just change the
2856 argument names; these functions don't really do anything.
2857 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2858 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2859 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2860 Also, use prototyped definitions, and get rid of the extra
2862 (scm_fptob, scm_pipob): We don't need casts here any more.
2863 * strports.c (prinstpt): Use prototype declarations.
2864 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2865 and use SCM_STREAM to get the string info. Also, use prototyped
2866 definitions, and get rid of the extra declarations.
2867 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2870 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2871 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2873 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2874 scm_fgets, for consistency.
2875 (scm_fptop, scm_pipob): References updated.
2877 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2879 Include the source location in error messages for scripts.
2880 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2881 stack is still there when we catch the error.
2882 * throw.c (handler_message): If we are handling an error with a
2883 message, then put together the proper arguments and call
2884 scm_display_error, instead of scm_display_error_message. That
2885 displays source location, if it can find it.
2887 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2889 * gc.c (scm_unprotect_object): Change this so that calls to
2890 scm_protect_object and scm_unprotect_object nest properly.
2891 (scm_protect_object): Doc fixes.
2893 * strings.c (scm_string_set_x): Require the argument to be a
2894 writable string, not a substring or a symbol.
2895 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2896 (Thanks to John Redford and Charbel Jacquin.)
2898 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2900 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2902 * eval.c (safe_setjmp): Remove this misunderstanding.
2903 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2906 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2908 * libguile.h: Mark these as C declarations, for compilation by C++
2911 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2912 __cplusplus clause. I seriously doubt this ever worked the way
2913 the author seems to have intended.
2915 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2917 Utterly needless cleanups to hopelessly messy code.
2918 * ports.c: Doc fixes.
2919 (scm_fflush): Moved to ...
2920 * genio.c (scm_fflush): ... here, amongst all the other port
2921 method invocation functions.
2922 * genio.h, ports.h: The prototype moves too.
2924 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2926 * backtrace.c (display_error_body): The current frame does not
2927 always have a parent frame; consider a function called directly
2928 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2931 * alloca.c (alloca): Undo yesterday's changes, and simply call
2932 malloc directly for storage, and abort if we don't get what we
2933 want. The situation is much simpler --- just call malloc. Emacs
2934 has bizarre/evil requirements (signal handlers might malloc unless
2935 you set this global flag, so you have to set the flag around all
2936 calls to malloc) which we are certainly not going to conform to,
2937 so we can do the simple and obvious thing.
2939 * coop.c (coop_condition_variable_wait): Make this function
2940 static. It's only useful internally --- you should never just
2941 wait on a condition variable.
2942 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2944 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2946 * unif.c (scm_array_set_x): Accept any kind of number as an
2947 element for a uniform vector of doubles. This is more consistent
2948 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2950 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2951 works; I can't conveniently test it myself. (Thanks to Dvid
2952 Tillman for the bug report.)
2954 * init.c: Doc fixes.
2956 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2957 from here, not from scm_compile_shell_switches (which is a pretty
2958 dumb place to do it).
2959 (scm_load_startup_files): New function.
2960 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2961 * script.c (scm_compile_shell_switches): Don't load the startup
2963 (scm_ice_9_already_loaded): Variable moved.
2964 * init.c (scm_load_startup_files): Prototype for new function.
2965 * gh_init.c (gh_enter): Doc fix.
2967 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2969 Some anti-warning changes from Greg Harvey.
2970 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2971 warnings when it doesn't understand our NORETURN declarations in
2973 * posix.c (scm_mknod): Similar.
2975 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2977 * posix.c (scm_getpwuid): If we can't find an entry, return our
2978 own message, instead of using scm_syserror --- the getpwMUMBLE
2979 functions don't set `errno' to anything interesting.
2981 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2983 Get rid of warnings from the cooperative threading system.
2984 * threads.h (scm_single_thread_p, scm_yield,
2985 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2986 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2987 scm_wait_condition_variable, scm_signal_condition_variable): Add
2988 prototypes for these Scheme-visible functions.
2989 * coop-defs.h (coop_next_runnable_thread,
2990 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2991 Prototypes for these here, even though they're from iselect.c.
2992 (coop_condition_variable_wait, coop_join): Add prototypes.
2993 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2994 scm_threads_free_condvar): Make these smob functions static.
2995 * coop-threads.h (coop_init): Give this a real prototype.
2996 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2997 (coop_next_runnable_thread): No need to provide prototype; it's in
3000 * scmconfig.h.in: .detarenegeR
3002 * iselect.c, threads.c: Doc fixes.
3004 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3006 * Makefile.in: Regenerated with a patched automake, to get
3007 dependency generation right when using EGCS.
3009 * inet_aton.c (inet_aton): Add prototype, to remove compiler
3010 warning. (Thanks to Robert Pluim.)
3012 * inet_aton.c (inet_aton): Reassure the compiler that the
3013 arguments to the <ctype.h> macros are all unsigned characters, not
3016 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3018 Getting rid of more warnings...
3019 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
3020 today's change to ../configure.in.
3021 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
3022 * scmconfig.h.in: Regenertaded.de.,.__
3023 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
3024 (scm_localtime, scm_mktime): Use a const char * to manipulate the
3027 * readline.c: Doc fix.
3028 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
3029 * readline.h (scm_filename_completion_function): Add prototype.
3030 (scm_init_readline): Make this into a prototype.
3032 * readline.c (scm_filename_completion_function): Use SCM_PROC to
3033 declare this, instead of calling scm_make_subr manually.
3035 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
3037 * readline.h (scm_init_readline): Add prototype for this.
3038 (scm_init_readline): Make this a real prototype.
3040 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3042 Warning fixes from Maciej Stachowiak:
3043 * backtrace.h (scm_display_application, scm_backtrace): Add
3045 * debug.c (scm_m_start_stack): Make this function static.
3046 * fluids.h (scm_fluid_p): Add prototype.
3047 * procprop.c (scm_i_procedure_arity): Make this function static.
3048 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3049 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.

3054 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3056 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3058 * gh.h: took out the definitions of vset and vref, since they are
3059 replaced by the proper vector routines that correspond to the R4RS
3062 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3064 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3065 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3066 third argument, a C expression that should result in a SCM value,
3067 which is used to initialize the variable. Reimplemented
3068 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3071 * version.h (scm_libguile_config_stamp): Add prototype.
3072 (From Maciej Stachowiak.)
3074 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3076 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3077 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3079 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3081 * print.c (scm_iprin1): Rather than having one i, and using it in
3082 several places, declare a fresh i local to each block where it is
3083 used, and give it a signedness appropriate to its use in each case.
3084 (scm_iprlist): Same.
3086 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3087 comparison warnings.
3089 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3090 signed/unsigned clashes.
3092 * posix.h (scm_tmpnam): Added prototype.
3094 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3095 scm_make_subclass_object): Add external prototypes.
3097 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3098 comparison is okay here.
3100 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3102 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3103 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3105 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3108 * load.c (swap_port): Make this function static.
3110 * load.c (scm_search_path): Make max_path_len and max_ext_len
3111 unsigned, since they're compared against string sizes.
3113 * load.c (init_build_info): Make i unsigned.
3115 * ioext.h (scm_read_line): Add prototype.
3117 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3118 scm_hash_fn_remove_x): Make hash bucket index local variable k
3119 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3120 accurately as possible.
3122 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3123 comparisons, and range checking to make sure those casts are
3126 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3127 signed/unsigned comparisons.
3129 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3130 avoid signed/unsigned comparisons.
3131 * smob.h (scm_numsmob): Change extern declaration to match.
3133 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3134 avoid signed/unsigned comparisons.
3135 * ports.h (scm_numptob): Change extern declaration to match.
3136 (scm_current_load_port, scm_set_port_line_x,
3137 scm_set_port_column_x): New prototypes.
3139 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3140 test code, and it causes warnings.
3142 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3143 gh_uniform_vector_ref): Added prototypes.
3145 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3146 debugging support unconditionally. That's backtrace.c, stack.c,
3147 debug.c, and srcprop.c.
3148 (EXTRA_libguile_la_SOURCES): Omit those from here.
3149 * Makefile.in: Regenerated.
3151 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3153 * options.c (scm_options): Bugfix: Allow empty list of options!
3155 * debug.c, debug.h (scm_single_step): Removed.
3156 (scm_with_traps): New procedure. This procedure could easily be
3157 written in Scheme but needs to be highly optimized.
3159 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3161 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3162 Check SCM_TRAPS_P before trapping.
3164 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3166 Changes to avoid signed/unsigned comparison warnings.
3167 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3168 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3169 so they can have appropriate types for each application. Make i
3170 signed. Use initializers in some spots. I'll probably pay for
3172 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3173 (scm_must_realloc): Make nm unsigned.
3174 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3175 (scm_init_storage): Use prototype-style definition, and make the
3177 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3178 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3180 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3181 avoid signed/unsigned comparison warnings, and because the return
3182 value of readlink may be -1. Don't bother casting the third
3183 argument to readlink.
3185 * filesys.c (scm_dirname, scm_basename): Move these to their own
3186 page, at the end of the file.
3187 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3189 * eval.h (scm_eval_options_interface): Add external prototype for this.
3190 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3192 * eval.c (scm_lookupcar1): Make this static.
3194 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3195 Make these prototype declarations, not K&R-style.
3197 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3198 unsigned comparison warning.
3200 * appinit.c: File removed. It had a single function in it, empty,
3201 whose reason for existence is explained in no documentation or
3202 comment. I think it's there as a default for some Tcl-style
3203 initialization, but Tcl abandoned that approach a while ago.
3204 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3205 (BUILT_SOURCES): Remove appinit.x.
3206 * Makefile.in: Regenerated.
3208 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3210 * Makefile.in: Regenerated using the last public version of
3211 automake, not the hacked Cygnus version.
3213 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3215 Remove Totoro kludge.
3216 * Makefile.in, scmconfig.h.in: Regenerated.
3217 * init.c, readline.c: Don't check if TOTORO is #defined.
3219 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3221 * Makefile.am: Adjust for new thread configuration system.
3222 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3223 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3225 (THREAD_LIBS): Definition deleted; automake will generate such
3226 things automatically.
3227 * Makefile.in: Regenerated.
3229 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3231 Simplify smob and port marking; set the mark bit in the generic
3232 marking code, and make marker routines only responsible for
3233 turning up outgoing pointers.
3234 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3235 before calling the marking function. Don't call the marking
3236 function if it's zero.
3237 * markers.c (scm_mark0): Just return #f. This function isn't
3238 necessary at all now, but it's harmless to call it. We'll leave
3239 it in so other folks' code doesn't croak at link time.
3240 (scm_markcdr): Don't call SCM_SETGC8MARK.
3241 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3242 * dynl.c (mark_dynl_obj): Same.
3243 * root.c (mark_root): Same.
3244 * srcprop.c (marksrcprops): Same.
3245 * unif.c (markra): Same.
3246 * variable.c (scm_markvar): Same.
3247 * ports.c (scm_markstream): Same.
3248 (void_port_ptob): Specify zero for our marking function.
3249 * debug.c (debugobjsmob): Same.
3250 * dynwind.c (guardsmob): Same.
3251 * filesys.c (dir_smob): Same.
3252 * fluids.c (fluid_smob): Same.
3253 * fports.c (scm_fptob, scm_pipob): Same.
3254 * mallocs.c (mallocsmob): Same.
3255 * regex-posix.c (regex_t_smob): Same.
3256 * smob.c (freecell, flob, bigob): Same.
3257 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3258 * throw.c (jbsmob, lazy_catch_funs): Same.
3260 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3262 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3263 scm_copy_tree on code in order not to let memoized code to leak
3264 out. Thus, scm_copy_tree needs to copy vectors as well since
3265 quasiquote can introduce evaluated code also inside vector
3268 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3270 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3272 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3273 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3276 * unif.c: Say that ivect and uvect are of type signed and unsigned
3277 long instead of int in commentary so that it correctly describes
3280 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3282 * stime.c: Removed declaration of strptime. (It should be
3283 declared by the system headers. If it turns out that some systems
3284 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3286 * stime.h: Renamed TIMEH --> STIMEH
3288 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3289 to increase portability, don't use structure assignment.
3290 (Thanks to Nicolas Neuss.)
3292 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3294 (finalize_fd_sets): Added empty statement after last case label.
3295 (Thanks to Nicolas Neuss.)
3297 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3300 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3302 * init.c, readline.c: OK, I won't have these readline.x bug
3303 reports anymore. We've had them since April. The current reason
3304 is a completely unintelligible failure of totoro.red-bean.com to
3305 do the test for rl_getc_function in libreadline correctly. This
3306 kludge overrides the test if we're on totoro so that the snapshot
3307 generation process can work.
3309 * readline.c: Define a strdup replacement if not existent on system.
3311 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3313 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3314 This change makes scm_make_vector R5RS compatible. We cannot keep
3315 the third argument since people want to be able to deduce the form
3316 of the C function call only by looking at R5RS. (At the same time
3317 we have removed some unnecessary complexity!)
3319 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3320 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3321 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3322 argument in call to scm_make_vector.
3324 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3326 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3327 This macro is useful in applications.
3329 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3331 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3332 (scm_parse_path, scm_search_path): New Scheme level procedures.
3334 * load.h (scm_internal_parse_path, scm_parse_path,
3335 scm_search_path): Declared.
3337 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3339 * filesys.c (dirname, basename): New procedures.
3341 * init.c (scm_boot_guile_1): Removed condition around
3344 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3345 new data type (guards) for representation of C level guards and
3346 data on the wind chain.
3347 (scm_internal_dynamic_wind): New function.
3349 * dynwind.h: Declare scm_internal_dynamic_wind.
3351 * root.h (scm_root_state): Added scm_cur_loadp.
3353 * root.c (mark_root): Added comment about cur_loadp.
3355 * load.c: #include "dynwind.h";
3356 (scm_primitive_load): Use scm_inner_dynamic_wind to update
3359 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3361 * ports.c (current-load-port): New procedure.
3363 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3365 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3366 not a tty, return #f.
3368 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3369 to Julian Satchell and Roland Kaufmann.)
3371 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3372 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3374 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3376 * debug.h, debug.c (scm_start_stack): New function. Implements
3377 the guts of old scm_m_start_stack.
3379 * debug.c (scm_m_start_stack): Use scm_start_stack.
3381 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3382 start_stack and restart_stack. (These have static scope.)
3384 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3386 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3387 readline functions to come in release 2.3. (Thanks to Chet
3389 (handle_errors): Use the above functions.
3391 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3393 * readline.c: Improvements for readline support: Handle errors
3394 better; Implement before-read-hook.
3396 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3398 * init.c (scm_boot_guile_1), readline.c: Test for
3399 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3400 assure that we have version >= 2.1.)
3402 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3404 * readline.c (scm_readline): Defer interrupts while we're calling
3407 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3408 away the string to add_history.
3409 (completion_function): Do completion for readline. (Thanks to
3411 (scm_filename_completion_function): New procedure: Filename
3413 (current_input_getc): New function. Use this one instead of
3414 standard getc from readline.
3416 * throw.c, throw.h (scm_handle_by_throw): New function: This
3417 handler throws errors to next handler on the dynwind chain.
3419 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3421 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3424 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3426 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3428 (scm_procedure_properties): Modified to return arity together with
3430 (scm_procedure_property): Added the read-only property `arity'.
3431 (scm_set_procedure_property_x): It is an error to set the `arity'
3434 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3435 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3437 * procprop.h (scm_sym_arity): New symbol.
3439 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3440 to set the dispatch procedure of an operator or entity object.
3442 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3443 Made procedure slots read-only.
3445 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3446 scm_tcs_cons_gloc case in zero args switch; Fixed args
3447 construction for operators in scm_tcs_cons_gloc case in two args
3450 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3452 * fluids.c: Removed use of assert.h (in order to avoid
3455 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3457 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3459 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3460 change makes the evaluator safer at the cost of evaluation speed.
3461 It handles the case when the user has added a non-immediate
3462 improper end of the application form, e.g., `(+ 0 . x)'.
3463 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3464 minimize the extra cost as much as possible. The new code is
3465 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3466 problem with structs planted directly in the code (e.g. by a
3467 macro). This no longer causes segmentation fault. (Thanks to
3470 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3471 arg `proc' in order to be able to throw errors; New argument
3474 * Removed extra #include "debug.h"
3476 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3478 * scmsigs.c: Declare usleep as returning void on some systems.
3479 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3482 * coop.c (usleep): Return void on some systems.
3484 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3486 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3488 * coop.c: Changed return type of usleep to int.
3490 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3491 isn't found in the OS.
3493 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3494 isn't enabled. (Thought that I had made this change ages ago...)
3496 * iselect.c: Declare bzero if not defined by OS.
3498 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3500 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3501 condition. (Thanks to John Tobey.)
3503 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3504 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3507 * __scm.h: Start the long-term project of moving to POSIX threads.
3508 Phase 1: Classification of all critical sections.
3509 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3510 for A sections. (See comments in __scm.h for details.)
3512 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3513 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3515 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3517 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3518 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3519 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3520 dependencies on $(srcdir)/Makefile.in
3521 $(top_builddir)/config.status in order to avoid circularity.
3523 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3524 from argc if argc was 0 initially.
3526 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3527 in generation of libpath.h.
3529 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3531 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3532 libguile from 2 to 3.
3534 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3536 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3538 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3540 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3541 scm_set_port_column_x, scm_port_filename,
3542 scm_set_port_filename_x): Removed optional arguments. Added
3543 proper argument checking.
3545 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3546 stack size in machine words.
3548 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3549 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3550 to Ole Myren Röhne.)
3552 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3554 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3555 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3557 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3560 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3561 procedure apply: Copy argument lists before pushing them unto the
3562 environment so that the environment won't get mutated due to
3563 manipulation of procedure arguments. This should perhaps be
3564 regarded as a temporary solution until someone finds a more
3565 efficient one. (Thanks to Maciej Stachowiak.)
3567 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3569 * script.c (scm_compile_shell_switches): Use "guile" as default
3570 zero arg if argc is NULL.
3572 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3574 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3575 is zero. (Thanks to Dirk Herrmann.)
3577 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3579 * ports.c (scm_add_to_port_table): First line is now line 0
3580 (was 1). (Interface changed according to suggestion by Per
3583 * backtrace.c (display_header): Add 1 to line and column numbers
3584 when presenting them to the user.
3586 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3587 from debug.c --> eval.c
3589 * eval.h, eval.c (scm_eval_options_interface): New options
3591 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3592 i.e. stacks for new threads.
3594 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3596 * eval.c (unsafe_setjmp): Removed with #if 0.
3598 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3601 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3602 to avoid compiler warnings.
3604 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3606 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3608 * throw.c (handler_message): Print message on current error port
3609 instead of default error port. (Thanks to Maciej Stachowiak.)
3611 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3613 * ports.c (scm_add_to_port_table): allocate in units of
3614 struct scm_port_table *, not struct scm_port_table.
3615 * posix.c (scm_close_pipe): remove the port from the port table
3617 Thanks to Rob Engle for both fixes.
3619 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3621 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3622 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3624 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3626 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3628 * backtrace.c (display_error_body, display_backtrace_body),
3629 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3630 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3631 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3632 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3635 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3636 don't receive the jmpbuf arg anylonger.
3637 (scm_catch): Don't accept a #f tag.
3638 (scm_throw): Check that key is a symbol.
3639 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3641 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3643 * async.c (async_pending): Removed declaration.
3645 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3647 * dynwind.c (scm_wind_chain): New debug function.
3649 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3650 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3651 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3652 extra layer of functions around the body and handler of a thread.
3653 This extra layer makes sure that the handler is called in the
3654 dynamic context of the surround (= empty dynwind list), but under
3655 the *dynamic root* of the body. We can not use the dynamic root
3656 of the surround since that root belongs to another thread => stack
3657 is not handled correctly. It may seem ugly to use this extra
3658 layer, but the extra cost in terms of execution time is really
3659 negligible compared to the total amount of time required to create
3660 a thread, and it would reduce maintainability to duplicate the
3661 crucial and complicated steps performed by cwdr.
3663 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3664 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3665 get re-enabled. The important effect of this is that interrupts
3666 are blocked during thread switching so that thread data structures
3667 don't risk getting messed up by an unfortunate signal.
3668 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3669 seems to do more aggressive optimization which actually move
3670 instructions around in these macros in a fatal way. Therefore:
3671 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3672 just superstitious...)
3673 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3674 This macro should be used instead of SCM_ASYNC_TICK since the
3675 latter doesn't do context switches any more.
3677 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3678 instead of SCM_ASYNC_TICK.
3680 * coop.c, iselect.c: Since thread switches are now performed with
3681 interrupts masked, we can't use the old mechanism of delivering
3682 signals immediately when they arrive. Signals must instead be
3683 delivered when the asyncs run *after* the end of the critical
3684 section in scm_internal_select. But this also means after context
3685 switch so that the signal will be delivered to a different thread.
3686 To avoid this, I have changed the protocol of
3687 coop_wait_for_runnable_thread and friends so that they are allowed
3688 to return the original thread. So, if a signal arrives during
3689 scm_internal_select, we won't any longer be forced do a context
3690 switch, but can remain in the same thread and deliver the signal
3693 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3694 scm_asyncs_pending and made it global.
3696 * iselect.c: Small fixes.
3698 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3699 coop_condition_variable_init, coop_condition_variable_wait,
3700 coop_condition_variable_signal): Changed return type from `void'
3701 to `int'. This is to adhere closer to the pthreads interface.
3702 This, in turn, is part of an attempt to provide C versions of the
3703 mutex and condition variable primitives which can be part of a
3704 frontend to COOP or pthreads.
3706 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3707 coop_condition_variable_destroy): New functions.
3709 * coop-threads.c (scm_wait_condition_variable): Use
3710 coop_condition_variable_wait_mutex.
3712 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3713 Definitions moved to coop-defs.h.
3715 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3716 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3717 scm_cond_destroy): New C interface to mutecis and cond vars.
3719 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3721 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3723 * iselect.c: Now several threads can wait on the same file
3724 descriptor. The behaviour is compatible with OS select: All
3725 threads waiting for the fd return with the same status.
3727 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3729 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3730 Can spawn a thread from application C code.
3732 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3734 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3735 gh_doubles2scm): New functions.
3737 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3739 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3740 commented-out version of gh_eval_str()
3742 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3744 * socket.c (scm_bind): free soka after use.
3746 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3748 * stime.c (tzvar): new variable.
3749 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3750 avoid memory leaks when allocating.
3752 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3754 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3757 * gc.c, tags.h: Doc fixes.
3759 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3761 * eval.c (macro-eval!): Removed. This function was a design bug.
3762 It allowed memoized code to leak out to the scheme level. Most
3763 things that you could do with `macro-eval!' can be done with
3766 1997-12-20 Tim Pierce <twp@skepsis.com>
3768 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3769 scm_fgets now depends on ftell(3) to know how many bytes were
3772 1997-12-15 Tim Pierce <twp@skepsis.com>
3774 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3775 dealing with strings.
3777 1997-12-13 Tim Pierce <twp@skepsis.com>
3779 Make %read-line more suitable for implementing read-line efficiently.
3780 * ioext.c (scm_read_line): Strip the terminating newline from a
3781 string, and return a cons of the string and its terminator.
3783 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3784 of the string that is read is stored in this memory location.
3785 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3786 * genio.c, genio.h (scm_do_read_line): Update caller.
3787 * ports.h (scm_ptobfuns): Update typedef.
3788 * fports.c (scm_fptob, scm_pipob): Update struct.
3790 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3792 * filesys.c (set_element): Return file descriptor.
3793 (fill_select_type): Return the highest file descriptor.
3794 (scm_select): Tell select about the highest file descriptor. On
3795 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3796 Therefore the extra overhead for calculating the maximum fd seems
3797 to be more than compensated. Is this correct? In any case,
3798 scm_internal_select will be much faster with this info.
3799 (scm_select, fill_select_type, set_element): Don't accept any kind
3800 of object in the file descriptor list or vector.
3802 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3804 * iselect.c (finalize_fd_sets): Bugfix.
3806 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3808 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3809 when using scm_internal_select (since we might switch to another
3812 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3814 * simpos.c (scm_system): always define: use sysmissing if not
3815 available. Check for HAVE_SYSTEM instead of _Windows (does
3816 Windows lack system or does it have an unusable one?).
3817 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3818 Let the argument be optional: if not supplied, call system(NULL).
3820 * ports.c (scm_close_port): relax the type check from OPPORTP to
3821 PORTP; closing a closed port is allowed.
3823 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3825 * fports.c (scm_fgets): Return if the last char in a chunk is
3826 newline. When fgets returns a string whose length is `size-1', it
3827 is ambiguous whether a whole line was retrieved, so we must check
3828 explicitly whether a line terminator is present.
3830 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3832 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3833 before taking the CDR. (Thanks to Harald Meland.)
3835 * filesys.c (scm_stat): Slightly optimized.
3837 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3839 * ports.c (scm_close_port): Make sure the port is open before
3842 * guile-snarf.in: Pass args through to gcc in a way that preserves
3843 whitespace boundaries. (Thanks to Greg Badros.)
3845 1997-12-02 Tim Pierce <twp@skepsis.com>
3847 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3848 statement. (Thanks to Doug Evans for pointing this out.)
3850 1997-12-01 Tim Pierce <twp@skepsis.com>
3852 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3854 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3856 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3857 errno macro expansion of this field name. (errno is a C
3858 preprocessor macro on some systems.)
3860 1997-11-29 Tim Pierce <twp@skepsis.com>
3862 * iselect.c: Doc fix.
3864 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3866 * init.c (scm_start_stack): Removed initialization of
3867 scm_the_last_stack_var.
3869 * backtrace.h: Declare scm_the_last_stack_var.
3871 * backtrace.c: Define scm_the_last_stack_var.
3873 * root.c (mark_root): Don't mark the_last_stack_var.
3875 * root.h (scm_root_state): Removed the_last_stack_var.
3877 * throw.c: Added #include "fluids.h"
3878 (ss_handler): `the-last-stack' is now a fluid.
3880 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3881 --> the_last_stack_fluid.
3883 * backtrace.c: Added #include "fluids.h"
3884 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3885 (scm_backtrace): `the-last-stack' is now a fluid.
3887 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3888 after scm_init_fluids.
3890 1997-11-28 Tim Pierce <twp@skepsis.com>
3892 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3894 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3895 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3897 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3899 * iselect.c (coop_next_runnable_thread,
3900 coop_wait_for_runnable_thread): Disable interrupts so that no
3901 async is executed before a potential error_revive.
3902 (scm_internal_select): Disable interrupts during the parts of the
3903 code which manipulate the sleep queue and the file descriptors.
3905 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3907 * Makefile.am: Added iselect.c and iselect.h.
3909 * coop.c (coop_qinit): Initialize fields used by
3910 scm_internal_select.
3911 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3912 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3913 replacement in iselect.c.
3914 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3915 coop_join): If GUILE_ISELECT enabled, use
3916 coop_wait_for_runnable_thread instead of
3917 coop_next_runnable_thread.
3918 (usleep, sleep): New replacements for system functions if
3919 GUILE_ISELECT is enabled.
3921 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3923 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3925 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3926 iselect.h. Implement Scheme level `select' using
3927 scm_internal_select. (See NEWS.)
3929 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3931 * init.c: Call scm_init_iselect.
3933 * iselect.h, iselect.c: New files. Implements
3934 scm_internal_select. (See NEWS.)
3936 1997-11-27 Tim Pierce <twp@skepsis.com>
3938 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3939 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3940 and scm_must_free, since ultimately the string returned will be copied
3941 by scm_makfrom0str anyway. Also, read any characters that may have
3942 been pushed onto the port with scm_ungetc.
3943 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3944 * ioext.c (scm_read_line): Free string after Guilifying it.
3945 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
3947 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3949 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3951 * gh.h: Safely wrap prototypes for c++ usage.
3953 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3955 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3956 gh_repl (argc, argv).
3958 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3960 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3961 and to invoke scm_shell().
3962 (gh_launch_pad): took out the loading of boot-9.scm from here,
3963 since it is probably best to let the user control that. In fact,
3964 gh_repl() now invokes scm_shell() which does that.
3966 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3968 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3971 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
3973 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
3974 yesterday's underscore patch. (Thanks to Marius Vollmer for
3977 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
3979 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
3980 DLSYM_ADDS_USCORE is not defined.
3982 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
3984 * gh_data.c (gh_uniform_vector_length):
3985 (gh_uniform_vector_ref): started implementing the uniform types in
3988 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3990 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3991 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3993 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3995 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3996 configure.in was changed).
3998 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
4000 * Makefile.am (modinclude_HEADERS): Include readline.h here.
4001 * Makefile.in: Regenerated.
4003 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
4005 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
4006 OPORT is an `open' port, not an output port.
4008 * filesys.c (scm_close, set_element, get_element, scm_chown,
4009 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
4010 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
4011 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
4012 scm_close_port, scm_port_line, scm_set_port_line_x,
4013 scm_port_column, scm_set_port_column_x, scm_port_filename,
4014 scm_set_port_filename_x, scm_port_mode,
4015 scm_close_all_ports_except, scm_set_current_output_port,
4016 scm_set_current_error_port): Likewise
4017 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
4018 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
4020 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
4021 * backtrace.c (display_backtrace_body): Likewise
4022 * fports (scm_setvbuf): Likewise
4023 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
4024 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
4025 scm_getpeername, scm_send, scm_sendto): Likewise
4026 * unif.c (scm_uniform_array_write): Likewise
4028 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
4030 Minor problems with substring-related tag changes.
4031 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
4032 exactly what we want to leave in to detect substrings.
4033 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
4034 * tags.h: Fix diagrams and comments describing the S tag bit;
4035 remove vestigial remarks about the D tag bit.
4036 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
4037 * strings.c: Formatting tweaks.
4039 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
4040 variable first; then SCHEME_LOAD_PATH, with a warning message.

4050 * Makefile.am (libguile_la_SOURCES): Include readline.c.
4051 * Makefile.in: Regenerated.
4052 * scmconfig.h.in: Regenerated, after change to ../configure.
4054 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4056 * gh.h: gh_vector_set -> gh_vector_set_x
4058 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4060 * gh_data.c (gh_vector_set_x): changed name to make it consistent
4061 with the ! -> _x mapping when going from Scheme to C.
4063 1997-10-19 Mark Galassi <rosalia@cygnus.com>
4065 * gh.h (gh_reverse):
4073 (gh_assoc): added these gh_ functions implemented as macros.
4075 * gh_predicates.c (gh_null_p):
4076 (gh_string_equal_p): added these two missing predicates.
4078 * gh_list.c (gh_append):
4083 (gh_set_cdr_x): added these routines as I go through and try to
4084 complete the picture R4RS functions that should be mirrored in the
4087 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4089 * tags.h (scm_tc7_substring): Changed the comment and code to
4090 conform with the changes below. Folks! We have suddenly two new
4091 free tc7 codes!!! Jummy, jummy!

4109 * gscm.c (gscm_run_scm): Don't init mbstrings module.
4110 * gc.c (scm_gc_mark): Don't handle mbstrings.
4111 (scm_gc_sweep): Likewise.
4112 * eval.c (SCM_CEVAL): Don't handle mbstrings.

4116 (scm_tc7_mb_string): Removed.
4117 (scm_tc7_mb_substring): Removed.

4120 Don't include "mbstrings.h".
4121 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
4122 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
4124 Don't include "mbstrings.h".
4125 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
4126 (SCM_SYMBOL_SLOTS): Define as 4.
4127 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
4128 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
4129 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
4130 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
4131 struct.c, threads.c, throw.c, unif.c, variable.c: Use new

4148 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
4149 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
4151 1997-10-12 Mark Galassi <rosalia@cygnus.com>
4153 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
4155 * gh_test_c.c (c_vector_test): some improvements on the vector
4158 * gh.h (gh_vector): this used to exist but do the wrong thing.
4159 Now it (almost) does the right thing, though it takes a list
4160 instead of the individual arguments. I need to see how it could
4162 (gh_list_to_vector): added this function as a macro. Corresponds
4163 to Scheme's (list->vector ...).
4164 (gh_vector_to_list): added this function as a macro. Corresponds
4165 to Scheme's (vector->list ...).
4167 * gh_data.c (gh_vector_ref): renamed from gh_vref to
4168 gh_vector_ref, so that it resembles the Scheme routines more.
4169 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
4170 resembles the Scheme routines more.
4171 (gh_make_vector): this used to be (stupidly) called gh_vector().
4172 This is the right name, since it does the same thing as the Scheme
4173 (make-vector ...) procedure.
4175 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4177 * ports.h: #include "libguile/print.h"
4179 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
4180 Some indentation fixes.
4182 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
4183 longer a user field; New field: class_flags.
4185 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
4187 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
4189 * gh_data.c (gh_bool2scm): new function which replaces
4190 gh_int2scmb(), which is now tagged as obsolete.
4192 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4194 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4195 macros should by convention not test for NIMPness.)
4196 (SCM_COERCE_OPORT): Adjust indentation.
4198 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4199 SCM_NIMP test before SCM_PRINT_STATE_P.
4201 * struct.c, struct.h, gc.c: Renamed:
4202 scm_struct_i_layout --> scm_vtable_index_layout
4203 scm_struct_i_vcell --> scm_vtable_index_vcell
4204 scm_struct_i_vtable --> scm_vtable_index_vtable
4205 scm_struct_i_printer --> scm_vtable_index_printer
4206 scm_struct_i_vtable_offset --> scm_vtable_offset_user
4208 * struct.c (scm_print_struct): Use new printer slot; Default
4209 printing: Also output hex code of vtable so that type identity
4210 will be indicated as well.
4211 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4212 Removed struct_printer_var; Removed struct-vtable-offset;
4213 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4214 vtable-offset-user): New constants.
4216 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
4217 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
4218 If this slot contains a procedure, use that to print structures of
4219 the type represented by this vtable.
4221 * print.c (scm_iprin1): Don't print arguments of macro
4222 transformers. (They are always: exp env.); Bugfix: Unmemoize
4223 transformer source with correct environment.
4225 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4227 Streamlining of call-with-dynamic-root:
4229 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
4230 there is now only one catch.
4231 (cwdr_outer_body): Removed.
4232 (cwdr_handler): New function.
4233 (scm_internal_cwdr): New function to perform the function of cwdr
4234 but take args that are more useful to C code. Also, the handler
4235 is now invoked *outside* of the new dynamic root, like the docs
4236 say. We no longer have to catch absolutely all errors, the caller
4237 is responsible for using a handler that does not throw, if he
4239 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4240 * root.h (scm_internal_cwdr): New prototype.
4242 Even more but risky streamlining:
4244 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4245 allocation of the jumpbuf of a root continuation. The changes
4246 below are controlled by it. They are now deactivated.
4247 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4248 the JMPBUF of the scm_rootcont to NULL before returning.
4250 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4251 when they are non-NULL.
4252 (scm_gc_mark): Likewise, mark only when non-NULL.
4254 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4255 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4257 * gc.c (scm_done_malloc): New function.
4258 gc.h (scm_done_malloc): New prototype.
4260 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
4261 (struct scm_print_state) [revealed]: New field.
4262 (scm_print_state_vtable): Make visible to the outside world for
4263 type checking purposes.
4264 (scm_valid_oport_value_p): New prototype.
4266 * print.c (scm_valid_oport_value_p): New function to check whether
4267 a certain value is acceptable as a port argument.
4268 (scm_print_state_vtable): New variable.
4269 (scm_free_print_state): Set `revealed' field to false.
4270 (scm_iprin1): Call user supplied closure printer with
4271 scm_printer_apply. Print in the traditional way when there isn't
4272 one or when it returns #f.
4273 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4274 Accept a port/print-state pair in addition to just a port.
4275 (scm_prin1): Don't return the print_state to the pool when it has
4277 (scm_printer_apply): Set `revealed' field of print_state to true.
4278 (scm_init_print): Set scm_print_state_vtable.
4279 (print_state_fluid, print_state_fluid_num): Removed.
4281 * throw.h (scm_handle_by_proc_catching_all): New prototype
4282 throw.c (scm_handle_by_proc_catching_all): New function
4284 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4286 * Makefile.in: Regenerated with automake 1.2c.
4288 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4290 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4291 was looping endlessly.
4293 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4295 * strports.c (scm_eval_string): Don't close the port.
4297 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4298 former returns a nice normal integer. (Thanks to Daniel
4301 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4303 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4304 makefile variable as a build parameter called LIBS. The
4305 build-guile program will use this, for the time being.
4306 * Makefile.in: Regenerated.
4308 Thanks to Shiro Kawai:
4309 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4310 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4313 * Makefile.in: Regenerated with automake 1.2a.
4315 * script.c (scm_compile_shell_switches): If we hit the -c or --
4316 arguments, don't set the car of (command-line) to scm_usage_name,
4317 the prettified name of the guile executable; give it the full
4318 path, the way shells usually handle $0.
4320 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4322 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4323 Scheme-level name `array-map' and renamed `serial-array-map' to
4324 `serial-array-map!'.
4326 * backtrace.c: Introduced exception handlers which now enclose
4327 `display-error' and `display-backtrace' so that error reporting
4328 won't get into infinite loops if an error occurs during displaying
4329 of the error. This can very easily happen with user supplied
4330 print call-back routines.
4332 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4334 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4335 the names `serial-array-map' and `array-map' should be removed.)
4337 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4339 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4340 Added #include "objects.h"
4342 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4343 Add #include "feature.h".
4345 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4346 (modinclude_HEADERS): Added objects.h.
4348 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4349 This test is needed at many places in the code and should be
4350 abstracted. (Motivated by the need of this test in libguiletk.)
4352 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4353 (scm_eval_string), load.c (scm_primitive_load,
4354 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4355 Use SCM_EOF_OBJECT_P.
4357 * eval.c (scm_init_eval): Add feature `delay'.
4359 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4361 * scmhob.h: Removed.
4363 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4365 * list.h (SCM_LISTn): New macros. Make list creation in C code
4366 prettier. The idea comes from STk.
4368 * sequences.h, sequences.c, append.h, append.c: Removed. These
4369 files implemented non-R4RS operations which would encourage
4370 non-portable programming style and less easy-to-read code.
4372 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4375 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4376 sequences.h, #include append.h.
4378 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4381 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4383 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4385 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4387 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4389 * eval.c: Added #include "objects.h"
4391 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4394 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4395 adjacent smob numbers.
4397 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4399 * procprop.h: Added declaration of scm_i_inner_name.
4401 * gsubr.c: New global symbol scm_i_inner_name.
4403 * debug.c (scm_procedure_name): Try procedure property
4404 `inner-name' if `name' fails.
4406 * print.c (scm_iprin1): Use scm_macro_name.
4408 * eval.c (scm_m_define): Give names to macros as well; Only the
4409 first top-level definition gives a procedure/macro a name.
4410 Otherwise confusing names can turn up in backtraces.
4411 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4412 `name'; Give names to macros as well.
4414 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4415 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4418 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4420 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4422 (prinmacro): Removed. The code has been moved/merged into print.c
4423 in order to decrease code redundancy. We want macros to print in
4424 a way equivalent to procedures, and it would be silly to duplicate
4425 the required code. (We don't want to maintain two places.)
4426 (macrosmob): Print field is now a NULL pointer.
4428 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4429 scm_macro_transformer): New prototypes.
4430 (scm_tc16_macro): Declared.
4432 * print.c (scm_iprin1): Added code for printing of macros. Macros
4433 are now printed in a way equivalent to procedures.
4435 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4437 * procs.h (scm_closure_p): Added declaration.
4439 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4441 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4442 Shouldn't pass "heap" as the subr name.
4444 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4446 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4447 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4448 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4449 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4450 SCM_BOOL_T. Any non-false value is true.
4452 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4454 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4455 scm_gensym): Added prototypes.
4457 * symbols.c (scm_gensym): New function. This will speed up
4458 certain types of applications (such as macro systems) which
4459 generate lots of symbols.
4461 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4463 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4465 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4467 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4468 specifier, since (2) or (2 . 3) would cause SEGV.
4469 (scm_transpose_array): more argument checking fixes.
4471 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4473 * Makefile.in: Regenerated.
4475 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4477 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4479 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4481 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4483 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4485 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4486 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4489 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4490 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4491 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4492 scm_array_p, scm_array_rank, scm_array_dimensions,
4493 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4494 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4495 scm_array_prototype): Added case scm_tc7_wvect.
4497 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4499 * errno.h: prototype for scm_strerror.
4500 * error.c (scm_strerror): new procedure.
4502 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4504 * list.c (scm_list_append_x): Allow non-pair as last argument.
4505 This is consistent with the R4RS append and is probably the
4506 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4508 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4510 * stime.h: prototype for scm_times.
4511 * stime.c (scm_times): new procedure.
4512 * ioext.c (scm_fseek): if the first argument is a file descriptor
4514 (scm_ftell): if the first argument is a file descriptor call lseek
4516 * filesys.h: prototypes for scm_open_fdes, scm_fsync.

4528 third argument is now optional.
4530 * posix.c (scm_execl, scm_execlp): make the filename argument
4531 compulsory, since omitting it causes SEGV.
4532 (scm_sync): return unspecified instead of #f.
4533 (scm_execle): new procedure.
4534 (environ_list_to_c): new procedure.
4535 (scm_environ): use environ_list_to_c. disable interrupts.

4541 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4542 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4543 argument to SCM_ASSERT. Furthermore, the name of the function
4544 should be passed as first argument when signalling
4545 SCM_WNA. (Thanks to Thomas Morgan)
4547 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4548 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4549 dispatches on the number of actual args has a default case
4550 reporting an internal error. This is a vestige from a version
4551 that mallocated a SCM vector to hold the arguments. In the
4552 current version this check is too late: if it ever happens we will
4553 have already overstepped the bounds of the array.
4555 Also, the patch [...] adds a check for too many actual arguments."
4557 mdj: Removed check for "internal programming error".
4559 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4561 * gh_io.c (gh_write): New function.

4576 fold in the functionality of scm_primitive_dup.
4577 (scm_primitive_dup): deleted.

4624 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied

4649 stream has been set.
4650 (scm_duplicate_port): deleted, there's now an implementation in

4703 data. (dynl_smob): Use it.
4704 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4705 the dynamic object data below the linking of the object to avoid
4706 memory leak when the linking code throws an error. Now the code
4707 leaks a whole dynamically linked library when must_malloc throws,
4708 but that should be much less likely.
4710 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4712 Changes to compile under gnu-win32, from Marcus Daniels:

4728 (scm_setpwent): For setpwent.
4729 (scm_setegid): For setegid.

4750 think this is left over from the (eq? '() #f) days.
4752 * read.c (recsexpr): Give this a dummy definition if
4753 DEBUG_EXTENSIONS isn't #defined.
4755 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

4772 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4774 * simpos.h: prototype for scm_primitive_exit.

4782 have to do this explicitly. Also, if regexp/basic is supplied, then
4783 turn off REG_EXTENDED.
4784 (scm_init_regex_posix): New regexp/basic symbol.
4785 (REG_BASIC): #define this if it is not already present.

4804 flag; I don't think we support it.
4805 (scm_make_regexp): Make sure the user doesn't pass the
4808 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4810 (scm_init_regex_posix): Define constants for the REG_mumble flags;

4828 * root.c: Establish a reliable catch-all handler for the new root.
4829 After all the Scheme handler function might signal an error too,

4832 (cwdr_outer_body): New function, to establish the user's handler,
4833 and pass control to cwdr_inner_body.

4835 control to cwdr_outer_body.
4836 (struct cwdr_body_data): New field, handler, to allow cwdr to pass

4845 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4846 the feeling that real thread systems will not need this...
4848 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4850 Try to detect when people are using one version of libguile and a

4862 primitive definitions under their Scheme names.
4864 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4865 1:2. Helps avoid confusion between installed and uninstalled libs.
4867 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4870 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4871 backslash from definition; this should be used like: GDB_INTERFACE;
4873 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4875 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
4876 new port unbuffered until its stream has been set.
4878 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4880 * ports.h: new prototype.

4890 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4892 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4893 argument plain char *.
4894 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
4896 * tag.c (scm_tag): Remove unreachable statement.
4897 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4898 top of the word, it should be unsigned.
4900 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4901 is defined, to avoid warnings; it's only used in the
4902 conflict-checking code. Which might go away anyway.
4903 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4904 conditionals; put the label definition in an #if too, to stifle
4907 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4908 ChangeLog-threads in the distribution.
4909 * Makefile.in: Regenerated.

4919 * load.c (scm_init_load_path): Append $(datadir)/guile to
4920 %load-path, so modules do not have to be installed in Guile's
4921 current version directory.
4923 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4925 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4926 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4927 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
4928 call the sysdep functions with deferred ints.

4949 condition during lookup (when using threads).
4950 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4951 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4954 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4956 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4957 supplied. (Change from Tim Pierce.)
4959 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4961 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4962 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4963 default and not `()'. `#f' is the canonical non-value in Scheme,
4966 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4968 * struct.c (struct_printer): New variable that holds a handle on
4969 the Scheme variable *struct-printer*. This variable can be set by
4970 Scheme code to override the printing of structures.
4971 (scm_print_struct): If struct_printer is set, call it. If it is
4972 not set, or returns #f, print the structure in the old fashion.
4973 Include "eval.h" for scm_apply.
4975 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4977 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4978 scm_struct_i_n_words to get the number of fields, not
4979 -scm_struct_n_extra_words.
4981 On the route to fancier struct printing:
4982 * struct.c (scm_print_struct): New function to print a structure.
4983 Include "genio.h" to support it. This function doesn't do
4984 anything interesting right now, but I think it should be here
4986 * struct.h: Include "print.h" and add prototype for
4988 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4989 print structures ourself.
4991 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4993 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4994 before applying the handler in case it doesn't return.
4996 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4998 * scmsigs.h, async.h: updated.
5000 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
5003 * posix.c (scm_uname): interpret only negative values as an error.
5004 Solaris normally returns a positive value.
5006 * script.c (scm_compile_shell_switches): if we are not going into
5007 an interactive repl, set scm_mask_ints to zero so that asyncs can
5010 * simpos.c (scm_system): don't ignore/unignore signals around
5013 * posix.c (scm_open_pipe): don't ignore/unignore signals around
5016 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
5017 done in boot-9.scm instead.
5019 * scmsigs.c, async.c: Major rewriting of signal handling code.
5020 (scm_sigaction): new procedure.
5021 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
5023 (scm_raise): return unspecified, throw error on failure.
5025 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5027 * regex-posix.c (scm_init_regex_posix): Register the "regex"
5028 feature, to help boot-9.scm decide whether to import the regex
5031 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5033 * eval.c: Include scmconfig.h at the beginning of the file so that
5034 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
5037 * regex-posix.c: #include "_scm.h" before conditionally #including
5038 <regex.h>; the former defines HAVE_REGCOMP.
5040 * regex-posix.c: #include <regex.h> conditionally, so the file is
5041 CPP'able (for dependency scanning) even on systems that don't have
5044 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5046 Add new R4RS-compliant syntax for keywords.
5047 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5048 regardless of the setting of the `keywords' read option.
5049 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5050 can be re-read no matter what the setting of the `keywords' read
5053 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5055 Add support for POSIX regular expressions.
5057 * regex-posix.c, regex-posix.h: New files. (Some code
5058 is taken liberally from rx/rgx.c in the old Guile dist.)
5060 * init.c: Include regex-posix.h.
5061 (scm_boot_guile_1): Call scm_init_regex_posix.
5063 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5064 Add regex-posix.[ch] sources.
5065 * Makefile.in: Regenerated.
5067 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5068 to do this automatically? It didn't for me, bleh.)
5070 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5072 * fports.c (print_pipe_port): New function.
5073 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5074 latter doesn't even take the right arguments.
5076 * Makefile.am: Increment shared lib revision number. I think
5077 sometimes the uninstalled Guile finds the installed shared lib;
5078 Gord says doing this might help. As things turned out, I can't
5079 say whether it does.
5080 * Makefile.in: Regenerated.
5082 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5083 passing it as the closure argument to scm_boot_guile. (Bill
5086 * ports.c (print_void_port, putc_void_port, puts_void_port,
5087 write_void_port, flush_void_port, getc_void_port, close_void_port,
5088 noop0): Use ANSI prototypes instead of K&R declarations, so the
5089 initialization of void_port_ptob gets aggressively type-checked.
5090 Fix arguments of print_void_port and write_void_port. (Bill

5124 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5126 * script.c (scm_find_executable): Use prototype-style definition
5127 here; apparently it's not quite right to have const in a prototype
5128 and then use a K&R declaration. I wonder if stuff like this will
5129 go away if we compile with -Wrequire-prototypes, or whatever that
5130 is... (Bernard URBAN)
5132 * scmhob.h: New text from Bernard URBAN.
5134 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5136 * script.c: Don't #define const on hpux. Configure takes care of
5137 this. (Thanks to Larry Schwimmer.)
5139 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5140 decide whether to #include <unistd.h>, instead of listing a bunch
5141 of systems. Don't #include stdio twice. Removed dyked-out
5142 definition of scm_find_impl_file.
5144 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5146 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5147 library version info to 1:0.
5148 * Makefile.in: Regenerated.
5150 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

5154 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5155 throw.c: Update copyright years; these files have been worked on
5156 significantly in 1997, but only had copyright years for 1996.
5157 Also, change name of copyright holder on some from Mikael
5158 Djurfeldt to Free Software Foundation; he has signed papers
5159 assigning the changes to the FSF.
5161 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5162 reason not to give the user the option.
5164 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5165 Return #f on end-of-file when scanning table (i.e. when called
5166 with no arguments). Try to catch errors, when we can.
5167 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5169 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5170 external declarations. These are useful.
5172 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5174 * posix.c: don't include <sys/select.h> or define macros for
5175 select, since they were not used in this file.
5177 * filesys.c (scm_select): make the fifth parameter microseconds,
5178 not milliseconds. let the fourth parameter be either a real value
5179 or an integer or #f. The first, second and third arguments can
5180 now be vectors: the type of the corresponding return set will be
5182 (set_element, get_element): new static procedures.
5184 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5186 * strports.c (scm_eval_string): New function.
5187 (scm_eval_0str): Trivially re-implemented in terms of
5189 * strports.h (scm_eval_string): New extern decl.
5191 * net_db.c (h_errno): Add extern decl for this.
5193 * fports.c (local_pclose): New function.
5194 (scm_pipob): Use it in the initializer here.
5197 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5198 Use a meaningful error message when signalling an error. For
5199 this, scm_gethost must check h_errno rather than errno.
5201 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5203 * Makefile.in: Regenerated, using automake-1.1p.
5205 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5207 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5208 not SCM_UNSPECIFIED.
5210 * script.c (scm_compile_shell_switches): don't append (quit) if
5212 (scm_shell): call scm_exit_status and exit on the result of the
5215 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5217 Ensure that shared substrings are handled properly when passed to
5218 a system call or other foreign function. Many thanks to Tim
5220 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5221 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5222 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5223 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

5225 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5226 (scm_display_error_message): use RO macros when strings may be RO.
5227 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5228 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5229 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

5233 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
5234 scm_strftime), vports.c (scm_make_soft_port): use
5235 SCM_COERCE_SUBSTR to make sure shared substrings are
5238 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5240 * error.c (scm_error): Add newline to error message.
5242 * init.c (scm_init_standard_ports): Doc fix.
5244 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5246 * dynl-shl.c: Completely replaced with new code from Bernard
5249 * script.c (scm_ice_9_already_loaded): New variable.
5250 (scm_compile_shell_switches): Use it.
5252 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5254 * filesys.c (scm_input_waiting_p): add missing third argument to
5257 * stime.c (scm_localtime): copy the result of localtime before
5258 calling gmtime in case they share a buffer.
5259 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5262 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5264 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5266 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5268 * Makefile.am (check-local): New target, which causes 'make check'
5269 to run gh_test_c and gh_test_repl, with some trivial input.
5270 * Makefile.in: Rgnrtd.
5272 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5274 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5277 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5279 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5280 sure how this was supposed to work.
5281 (scm_async_click): don't send SCM_TICK_SIGNAL.
5282 (scm_init_async): don't initialize %tick-thunk.
5284 * the following change doesn't affect the Scheme interface:
5285 gc-thunk is called at the end of garbage collection. however it's
5286 no longer implemented by pretending it's a signal.
5288 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5289 system async corresponding to scm_gc_thunk.
5290 * async.h: declare scm_gc_async.
5291 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5292 gc-thunk directly, instead of going through a signal handler.
5293 (scm_gc_async): new variable, points to the GC system-async.
5294 (scm_init_async): save the GC async as scm_gc_async instead
5295 of using system_signal_asyncs.
5296 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5298 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
5300 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
5301 Don't screw up if we're interrupted.
5302 * Makefile.in: Regeneradet.
5304 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5306 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5308 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5309 we're not using AM_INIT_GUILE_MODULE any more.
5310 * Makefile.in: Reneregated.
5312 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5314 Functions for finding variable bindings, grace à Tim Pierce.
5315 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5316 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5318 Get 'make dist' to work again.
5319 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5320 * Makefile.in: Regenerated, like a surry without a fringe on top.
5322 Changes for reduced Guile distribution: one configure script,
5324 * configure.in, configure: Removed.
5325 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5326 real configure script lives.
5327 * Makefile.in, scmconfig.h.in: Regenerated.
5329 * init.c: #include "script.h", to get prototype for script.c's
5332 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5334 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5335 scm_must_malloc, not raw malloc.
5337 * script.c (scm_compile_shell_switches): Dyke out debugging output
5340 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5342 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5344 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5345 system has them. Hope this is safe. Previously
5346 sys/timeb.h was included if HAVE_FTIME was defined or if
5347 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5348 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5350 * ioext.c (scm_setfileno): add missing third argument to
5351 scm_misc_error call.
5353 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5355 * eq.c (scm_equal_p): Correctly compare strings of different
5356 varieties. (Thanks to Tim Pierce.)
5358 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5360 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5361 #! block comment must occur on a line all by itself.
5363 Move most of the guts of shell command processing into libguile,
5364 so guile.c can be very small (and eventuallly auto-generated. (I
5365 mean, generated mechanically, not self-generated. Hmm.))
5366 * guile.c, script.c, script.h: New source files.
5367 * init.c (scm_boot_guile_1): Call scm_init_script.
5368 * libguile.h: #include "script.h".
5369 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5370 targets, for new executable.
5371 (libguile_la_SOURCES): Mention script.c.
5372 (modinclude_HEADERS): Add script.h.
5373 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5374 not dynamic linking is enabled. This is because we're generating
5375 executables now. Move CY_AC_WITH_THREADS call after those, so the
5376 values of cy_cv_threads_libs captures the libs chosen above.
5377 * Makefile.in, configure, aclocal.m4: Regenerated.
5379 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5380 We don't maintain this interface any more, and it just confuses
5383 * alloca.c: #include <scmconfig.h>, not <config.h>.
5384 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5385 it'll get included in disties.
5387 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5389 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5390 be distributed, because they confuse people.
5391 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5393 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5395 * configure.in: check for presence of gethostent (not present on
5396 OpenBSD by default).
5397 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5398 * configure, scmconfig.h.in: Regenerated.
5400 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5402 * backtrace.c (scm_backtrace): Split message string across
5403 newlines properly. GCC is more tolerant of this than other
5406 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5408 Merge threads directory into libguile.
5409 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5410 threads.h: New source files.
5411 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
5412 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5414 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5415 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5416 coop-threads.c.cygnus, coop-threads.h.cygnus.
5417 * configure.in: If we're using threads, include threads.o in
5419 * _scm.h, libguile.h: threads.h lives in this directory now.
5420 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5421 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5422 currently used, but brought along for information's sake.
5423 * ChangeLog-threads: log from old 'threads' directory.
5424 * Makefile.in, configure: Rebuilt.
5426 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5428 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5431 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5433 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5435 Merge GH interface library into libguile.
5436 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5437 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5438 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5439 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5441 (EXTRA_libguile_la_SOURCES): ... here.
5442 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5443 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5444 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5445 New variables, describing how to build the gh test programs.
5446 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5447 build the test programs, and we probably should have been linking
5448 libguile.la against them all along, to support AIX shared libs.
5449 Add cflags for threads to CFLAGS; add libs for threads to new
5450 variable THREAD_LIBS, used in Makefile.am.
5451 * ChangeLog-gh: log from old `gh' subdirectory.
5452 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5454 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5456 * acconfig.h: Undo change of Apr 9; including the definition of
5457 PACKAGE in the guile headers conflicts with applications' own
5459 * scmconfig.h.in: Regenerated.
5461 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

5470 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5472 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5473 have S_IFSOCK. This is the case under Ultrix.
5475 * posix.c (scm_status_exit_val, scm_status_exit_val,
5476 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5477 Ultrix versions of WIFSTOPPED, etc., which assume that their
5478 arguments are lvalues (hmm).
5480 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5482 * eval.c: Doc fixes.
5484 * throw.c: Doc fixes; rearranged.
5486 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5488 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5490 * acconfig.h: Added entry for PACKAGE.
5491 * scmconfig.h.in: Regenerated.
5493 Changes to work with automake-1.1n, which has better libtool support.
5494 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5495 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5497 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5499 * Makefile.in: Rebuild.
5501 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5503 * stime.c (scm_mktime): take an optional zone argument.
5504 (scm_localtime): check putenv return value.
5505 (scm_strftime, scm_strptime): moved from posix.c. move #include
5507 stime.h, posix.h: update prototypes.
5508 (bdtime2c, setzone, restorezone): new static procedures.
5509 (scm_mktime, scm_strftime): use them.
5510 (scm_strftime): don't call mktime before strftime. Use
5511 filltime for return value.
5512 (filltime): convert NULL zname to #f.
5513 (scm_strptime): return a count of characters consumed, not
5514 the remaining string.
5516 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5518 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

5521 Uncomment localtime and mktime.
5523 * configure.in: add AC_STRUCT_TIMEZONE.
5525 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5527 * stime.c (scm_init_stime): don't define ticks/sec.
5528 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5529 return value problem and is still portable.)
5531 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5533 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5534 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5535 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5536 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5537 cpp_err_symbols.c): Corresponding changes.
5538 * Makefile.in: Regenerated.
5540 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5542 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5543 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5544 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5545 * putenv.c: new file, from sh-utils 1.12.
5547 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5548 since allocation isn't for Scheme objects.
5549 (scm_putenv): copy strings before placing in the environment.
5551 * stime.c (scm_current_time): throw an error if time returns -1,
5552 instead of returning #f.
5553 (scm_get_internal_real_time, scm_get_internal_real_time): use
5554 scm_long2num for return value instead of SCM_MAKINUM.
5556 * stime.h: prototypes updated.
5558 * stime.c (scm_time_in_msec): apparently unused, deleted.
5560 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5562 * configure.in: check for gettimeofday.
5564 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5565 which may be more usefully portable than a gettimeofday interface.
5567 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5569 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5571 * Makefile.in: Regenerated.
5573 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5575 * stime.c (filltime): recovered static procedure.
5576 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5579 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5580 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5582 * posix.c (scm_mknod): split the mode argument into type and perms
5583 arguments, like the extra fields returned by stat.
5585 * fports.c (scm_pipob): set the close, free and print procedures.
5586 (scm_close_pipe): new procedure.
5588 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5589 define them in boot-9.scm
5591 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5593 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5594 wan't defined. Don't include fd.h.
5596 * Previously fd.h was regenerated whenever configure was run,
5597 forcing a couple of files to be recompiled.
5599 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5600 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5601 Check for _fileno as well as _file.
5603 * ioext.c: don't fd.h.
5604 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5607 * Change the stratigy for getting information about errno
5608 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5609 generating lists of symbols during the build process, which will
5610 not always work, include comprehensive lists in the distribution.
5611 To help keep the lists up to date, the "check_signals" and
5612 "check_errnos" make targets can be used.
5614 * configure.in: don't check for a command to extract errno codes.
5615 * Makefile.am: update file lists, remove errnos.list and errnos.c
5616 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5617 check_errnos targets.
5618 (CLEANFILES): remove errnos.c and errnos.list, add
5619 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5620 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5621 * errnos.default: deleted.
5622 * cpp_signal.c: new file.
5623 * cpp_errno.c: renamed from errnos_get.c.
5624 * cpp_err_symbols, cpp_sig_symbols: new files.
5625 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5626 * error.c (scm_init_error): #include cpp_err_symbols instead of
5628 * posix.c (scm_init_posix): don't intern signal symbols. #include
5631 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5633 * strop.c (scm_i_index): allow the lower bound to be equal to the
5634 length of the string, so a null string doesn't always give an error.
5636 * posix.h: new prototypes.
5637 * posix.c (scm_status_exit_val, scm_status_term_sig,
5638 scm_status_stop_sig): new functions, as in scsh. They break down
5639 process status values as returned by waitpid.
5641 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5643 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5644 configure doesn't know about it.
5646 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5648 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5650 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5651 which defines C variables with global linkage.
5653 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5655 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5658 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5660 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5661 has time to check why this doesn't work well with continuations.
5663 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5665 * Fix shell syntax error; some shells won't tolerate
5666 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5668 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5670 * posix.c (scm_uname): throw an error if uname fails instead
5673 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5675 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5678 * async.c (scm_ints_disabled): definition moved from error.c.
5680 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5682 * acconfig.h: Removed PACKAGE.
5684 * scmconfig.h.in: Regenerated.
5686 * snarf.h: g++ says it's non-portable not to specify the first
5687 argument in a varargs declaration. I introduced the first
5688 argument by using preprocessor conditionals.
5690 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5692 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5693 (scm_freopen): use RO string macros for filename and modes.
5694 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5696 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5697 (scm_mknod): use RO string macros for path.
5699 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5700 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5702 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5703 use SCM_ROSTRINGP and SCM_ROCHARS.
5705 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5707 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5710 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5711 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5712 support for byte vectors.
5714 * print.c (scm_iprin1): Limit number of vector elements printed
5715 according to pstate->length.
5717 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5719 * backtrace.c (scm_display_error_message): don't segv if message
5722 * error.h: prototype for scm_error_scm.
5724 * error.c (scm_error_scm): new procedure, reimplements scm-error
5725 in C and uses scm_error.
5727 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5729 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5730 pointer to the Scheme variable read-hash-procedures and intern it
5731 in scm_init_read. Modify scm_read_hash_extend and
5732 scm_get_hash_procedure to use the pointer.
5734 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5736 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5737 (SCM_KEYWORD_STYLE): defined.
5739 * read.c (scm_read_opts): add a keywords option. This isn't a
5740 boolean option, in case someone wants to add support for DSSSL
5742 Setup scm_keyword_prefix symbol.
5743 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5745 I've left keyword support disabled by default, since it doesn't
5746 seem to break the module system and it gives R4RS standard behaviour.
5747 It can be reactivated with (read-set! keywords 'prefix).
5749 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5751 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5752 before constructing arbiter.
5754 * eval.c (scm_m_define): Bugfix: Check that the object is a
5755 closure before setting the procedure property!
5757 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5759 * ports.c: Removed `ungetc-char-ready?'.
5761 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5763 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5764 (idea from Mikael: make it a pair so scm_permanent object only
5766 (scm_read_hash_extend): don't call scm_permanent_object.
5767 (ideas from Mikael): if chr is already in the list, replace its
5768 procedure instead of appending it again. If proc is #f, remove
5770 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5772 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5774 * gdbint.c (gdb_read): update scm_lreadr usage.
5776 * load.h: update prototypes.
5778 * load.c (scm_primitive_load, scm_read_and_eval_x,
5779 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5781 * read.h: add prototype for scm_read_hash_extend. Change args for
5784 * read.c (scm_read_hash_procedures): new variable.
5785 (scm_read_hash_extend): new procedure.
5786 (scm_get_hash_procedure): new procedure.
5787 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5788 for extended # processing.
5789 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5790 scm_read_token): remove case_i, sharp arguments. Change callers.
5792 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5794 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5795 (SCM_CASE_INSENSITIVE_P): define.
5797 * read.c: add case-insensitive option to scm_read_opts.
5798 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5799 to determine whether to convert symbol case.
5800 (default_case_i): definition removed.
5801 * read.c (scm_read_token): if case_i, downcase ic before doing
5804 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5806 * configure.in: Added configuration option `guile-debug'.
5807 Configure with --enable-guile-debug if you want a bunch of extra
5808 functions used for debugging when developing Guile.
5810 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5812 * procs.c (make-cclo): New undocumented debugging procedure: Make
5813 compiled closure with internal procedure PROC and length LENGTH.
5814 Only compiled if GUILE_DEBUG is defined.
5816 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5818 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5820 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5822 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5823 with 3 or more args internally to the evaluator.
5825 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5827 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5828 with 3 or more args internally to the evaluator. This is mainly
5829 because we don't want to pass entry and exit points of the
5830 debug support twice, but it also seems to increase the speed of
5831 the evaluator for such calls (e. g. (+ 1 2 3)).
5833 * backtrace.c (scm_display_application): New procedure:
5834 display-application; Set fancy printing parameters individually
5835 for different types of display (backtrace, error, application).
5836 (These should of course be customizable!)
5838 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5839 clear the CHECK-flags.
5841 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5843 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5845 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5847 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5848 from pairs with a GLOC in the car.
5850 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5851 otherwise `symbol-hash' will behave badly.
5852 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5853 we get segmentation fault!
5855 * symbols.c: Added #include "weaks.h". New functions:
5856 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5857 moved to an extraneous library when we split libguile.)
5859 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5861 * filesys.c (scm_stat): stat now takes fport arguments too as
5862 documented in the manual.
5864 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5866 * debug.c (scm_single_step): Bugfix: Call continuation with
5867 scm_call_continuation instead of throwing to it.
5869 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5871 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5872 argument wasn't declared to be optional.
5874 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5876 * stime.c (scm_init_stime): Add feature "current-time".
5878 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5880 * throw.h: prototype for scm_exit_status.
5881 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5882 args to derive an exit status. Allows (quit) to work from a
5884 (scm_exit_status): new function.
5887 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5889 * eval.c (scm_deval): Removed some old code.
5890 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5892 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5895 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5898 * procs.c: Introduce the existent C function scm_thunk_p at the
5899 Scheme level as well.
5901 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5903 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5904 used from C to easily lookup the value of a symbol in the current
5907 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5909 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5910 scm_init_unif in this file. This will also fix a previous problem
5913 * configure.in: Added AM_MAINTAINER_MODE
5915 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5917 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5920 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5922 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5923 source files that are not always included in libguile but should
5924 have their dependencies calculated by automake. This variable is
5925 recognized by automake, no further magic is needed.
5926 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5927 to deal exclusively with *.lo files, as it seems. The *.o files
5928 are built automatically when the corresponding *.lo file gets
5931 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5933 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5936 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5938 * unif.c (scm_array_set_x): minor change to argument error checking.
5940 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5942 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5943 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5944 They should only be included in the library at configure.in's
5946 (libguile_la_LDADD): Include the appropriate .lo files here.
5947 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5948 so we know when to build them (and their .lo bretheren).
5949 * configure.in (LIBLOBJS): New substituted variable. We let
5950 configure decide which .o files to include in LIBOBJS, and then
5951 put the corresponding list of .lo files in LIBLOBJS. The latter
5952 is what we pass to libtool.
5953 * Makefile.in, configure: regenerated.
5955 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5957 * symbols.c (scm_sysintern0): New function. Contains the core of
5958 old scm_sysintern but doesn't take a second value argument.
5959 (scm_sysintern): Now uses scm_sysintern0.
5960 (scm_sysintern_no_module_lookup): Renamed to
5961 scm_sysintern0_no_module_lookup and doesn't take a second value
5962 argument any longer.
5964 * symbols.h (scm_sysintern0: Added declaration.
5966 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5967 scm_sysintern when interning option keys. Otherwise we risk
5968 destroying the values of already interned variables.
5970 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5971 scheme-level boolean (use SCM_NFALSEP).
5973 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5975 (scm_backtrace): New function. (C version of old function from
5976 boot-9.scm) Motivation: Make it possible to display backtraces
5977 without depending on boot-9.scm. (I'm uncertain if this
5978 motivation is good enough...)
5980 * root.h (scm_root_state): Add member the_last_stack_var.
5981 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5983 * root.c (mark_root): Mark scm_the_last_stack_var.
5985 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5988 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5990 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5991 1. mark_lazy_catch didn't mark the smob.
5992 2. Both functions above have standard variants:
5993 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5994 free_lazy_catch --> scm_free0.
5996 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5998 * throw.c (scm_internal_lazy_catch): New function.
5999 (scm_lazy_catch): Rewritten to use it.
6000 (scm_ithrow): Handle the new lazy catch representation.
6001 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
6002 that doesn't have a jmpbuf is a lazy catch clause.
6003 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
6004 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
6005 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
6007 (scm_init_throw): Register the new lazy-catch smob type.
6008 * throw.h (scm_internal_lazy_catch): decl for new function.
6010 * throw.c (scm_internal_catch): Doc fixes.
6012 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
6013 configure.in. Including this might cause problems if applications
6014 that link against libguile include their own copies of alloca, but
6015 if they're using autoconf, they should be adding libguile to LIBS
6016 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
6017 the copy in libguile, and things will be okay. (I think.)
6019 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6021 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
6023 strop.h: move prototypes too.
6025 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6027 * posix.c (scm_init_posix): don't intern EINTR since it's now done
6030 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
6031 etc. I deleted them from filesys.c long ago, but didn't
6032 notice they were here too (although ineffective since
6033 sys/stat.h wasn't included).
6035 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
6037 * eval.c: Don't define alloca in GCC case. gcc will automatically
6038 use __builtin_alloca if appropriate.
6040 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6042 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6043 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6044 that values of automatic variables are preserved. See comments
6045 for safe_setjmp for details.
6047 Change from Thomas Morgan:
6048 * variable.c: Include eq.h.
6049 (var_equal): New function.
6050 (variable_smob): Use var_equal as the discriminator for variables.
6052 * throw.c (s_throw): Remove extraneous declaration.
6054 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6055 * eval.c: Add necessary CPP cruft to support that.
6056 * configure, Makefile.in, scmconfig.h.in: regenerated.
6058 Change from Thomas Morgan:
6059 * procprop.c (scm_procedure_properties): Convert the Scheme
6060 boolean returned by scm_procedure_p into a C boolean before using
6061 it as a condition for SCM_ASSERT.
6062 (scm_procedure_property): Likewise.
6064 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6065 indications of Unixness.
6068 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6070 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6072 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6074 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6075 "unknown # object" error messages.
6077 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6078 (scm_i_index) and declare it static. Add a 'direction' argument
6079 to indicate what way the search should go.
6080 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6082 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6083 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6085 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6087 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6089 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6090 to avoid clash with various scsh forks.
6092 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6094 The following two changes (ramap.c, throw.c) are motivated by the
6095 apparent unportability of forward declarations of static arrays of
6096 the form `static foo bar[];'.
6098 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6099 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6101 * throw.c (scm_throw): Moved above scm_ithrow.
6103 * options.h: Removed the extern declarations of scm_yes_sym and
6104 scm_no_sym since these are static.
6106 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6108 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6110 * Makefile.am: remove AWK=@AWK@.
6111 Add a rule for generating errnos.list.
6112 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6114 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6115 don't extract errnos, just set a variable (avoids the
6116 need to recompile error.c just because configure is run.)
6118 * unif.h: update prototypes.
6119 * unif.c (scm_uniform_array_read,write): change the offset and
6120 length arguments to start and end, for consistency.
6122 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6124 * ioext.h: update prototypes.
6125 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6126 scm_read_line_x, it's a more general procedure using an
6127 interface from scsh. read-line and read-line! are now defined
6129 Note that the new read-line trims the terminator
6130 by default, previously it was appended to the returned string. An
6131 optional argument specifies how to process the terminator (scsh
6132 compatible). For the old behaviour: (read-line port 'concat).
6133 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6134 returns a pair, but is converted to multiple values if the scsh
6137 socket.h: update prototypes.
6138 * socket.c (scm_recvfrom): for consistency with other procedures,
6139 take start and end as separate optional arguments.
6140 (scm_recv, scm_recvfrom): don't allow the second argument
6141 to be a size, only a buffer. Change the scheme names to
6142 recv! and recvfrom!. Don't return the buffer.
6144 * ioext.h, posix.h: move prototypes too.
6145 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6146 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6147 "read.h" and "unif.h".
6148 * ioext.c: include "chars.h"
6150 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6152 * dynl.c: The dynamic linking and module registration functions
6153 are now defined even when dynamic linking is not available for the
6154 host system. Some of their functionality can be done without
6155 dynamic linking; when it's really needed, they throw errors.
6157 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6159 * configure.in: Only define DYNAMIC_LINKING when one of the system
6160 dependent functions is detected.
6161 * dynl.c (scm_dynamic_func): New function to get the address of a
6162 function in a dynamic object.
6163 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6164 produced by scm_dynamic_func as the thing to call.
6166 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6168 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6169 (scm_register_module_xxx, scm_registered_modules,
6170 scm_clear_registered_modules): New functions.
6172 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6174 * symbols.c (scm_sysintern): Renamed to
6175 scm_sysintern_no_module_lookup.
6176 (scm_sysintern): New function to take the place of the old
6177 scm_sysintern. It uses the current toplevel lookup closure to give
6178 the symbol its value. This is a temporary hack to put packages
6179 like gtcltk into their own module.
6180 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6181 us whether `scm_top_level_lookup_closure_var' has been initialized
6183 * eval.c (scm_init_eval): Set it.
6185 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6187 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6188 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6190 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6192 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6193 scm_sys_dup): deleted: FD capability will be added to other
6195 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6196 scm_fd_free, fd_smob, scm_intern_fd.
6197 (scm_open): renamed from scm_sys_open. Return a port instead of
6198 an FD object. Make the mode argument optional.
6199 (scm_sys_create): deleted, it's just a special case of open.
6200 (scm_init_filesys): move interning of constants O_CREAT etc.,
6201 here (were previously using SCM_CONST_LONG macro).
6202 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6204 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6205 include "fports.h" and <stdio.h>
6206 (scm_stat, scm_select): don't support FD objects.
6208 * error.h: adjust scm_syserror_msg prototype.
6209 * error.c (scm_syserror_msg): take an extra argument for errno.
6210 Using the global value didn't always work, since it could be
6211 reset by procedure calls in the message or args arguments.
6213 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6214 I don't understand why the check was there (and what about the
6217 * strop.c (scm_string_copy): allow shared substrings to be copied.
6219 * unif.h: corresponding change to prototypes.
6220 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6221 recognize two new optional arguments: offset and length. Allow
6222 the port argument to be an integer (file descriptor, for scsh).
6223 Include <unistd.h> for "read" prototype.
6225 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6227 * socket.c: don't include filesys.h.
6229 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6231 * Makefile.am: add AWK=@AWK@ (?)
6233 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6235 Add a rule to generate errnos.c from errnos.
6236 * error.c (scm_init_error): include errnos.c.
6237 * errnos_cnvt.awk: new file, converts the list of errno codes to
6239 * errnos_get.c: new file.
6240 * errnos.default: new file, contains errnos to try if they can't
6241 be extracted from errno.h.
6242 * configure.in: if using GCC, try and extract errno codes from
6246 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6248 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6249 * Makefile.am: Made libguile into a libtool library.
6250 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6251 Set libtool_libs to indicate that libguile is a libtool library.
6252 See guile/ChangeLog for details.
6253 * .cvsignore: ignore "*.lo", the libtool library objects.
6255 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6257 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6258 use htons in getservbyport argument.
6260 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6262 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6263 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6266 * objprop.c (scm_object_property): No need to take the CDR of the
6267 value returned by scm_object_properties, since Aug 20 change.
6269 * configure.in: When checking for struct linger, #include
6270 <sys/types.h> as well as <sys/socket.h>. I've never known
6271 <sys/types.h> to cause any portability problems, and Solaris's
6272 <sys/socket.h> needs it.
6273 * configure: Rebuilt.
6275 I think the Sun compiler has chosen a perverse way to interpret
6276 ANSI declarations combined with K&R definitions. We'll
6277 appease it a little bit. But when it invades France, we fight.
6278 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6279 * print.h (scm_iprlist): Here too.
6280 * numbers.c (scm_divbigdig): Change definition to match
6281 declaration in numbers.h.
6282 * unif.c (scm_makflo): Change definition to match declaration in
6285 * init.c (scm_boot_guile): Don't return the value of
6286 scm_boot_guile_1. This function doesn't return a value;
6287 scm_boot_guile_1 doesn't return a value (or return at all).
6289 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6292 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6293 compile. I have a feeling this function is a bad idea anyway ---
6294 one should always test for features, not systems.
6296 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6297 semicolons. Only pure luck kept this from being noticed earlier.
6299 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6301 * socket.c (scm_recvfrom): Added missing semicolon.
6303 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6305 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6306 the buffer and start and end positions for scsh networking
6309 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6311 * configure.in: Revert previous change to this file; the problem
6312 is due to transient automake weirdness.
6313 * configure: Rebuilt.
6315 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6316 PLUGIN/guile.libs. configure generates the latter from the former.
6317 * Makefile.in: Rebuilt.
6319 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6320 need this if we install scripts, like guile-snarf.
6321 * configure: Rebuilt.
6323 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6325 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6327 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6329 * socket.c (scm_addr_vector): fix faulty scm_listify.
6331 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6333 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6334 style block comment is no longer considered an error.
6336 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6338 * PLUGIN/guile.libs.in: New file.
6339 * PLUGIN/guile.libs: Removed from repository.
6340 * configure.in: Create PLUGIN/guile.libs from
6341 PLUGIN/guile.libs.in. This is for including additonal libraries
6342 needed for dynamic linking.
6343 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6344 instead of PLUGIN/guile.libs.
6346 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6348 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6350 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6351 occurrences of the given element from the list, not just the
6352 first. This is how the Emacs Lisp functions behave, how the
6353 analogous Common Lisp functions behave, and (I believe) how the
6354 older Maclisp functions worked. I realize that this change may
6355 break code, but it seemed better to break it before the Guile
6358 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6359 Their prototypes were already present in gc.h, but they weren't
6361 (scm_init_storage): Initialize scm_protects.
6362 * root.c (scm_protects): New element of scm_sys_protects.
6364 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6366 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6368 * libguile.h: Added #include "libguile/net_db.h".
6370 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6371 30 change. That file is only meant for communication between the
6372 configuration process and load.c. If code linked against libguile
6373 wants to get at the paths mentioned in libpath.h, it can call
6374 functions declared in load.h.
6376 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6378 * libguile.h: Removed #include "libguile/fdsocket.h"
6380 * net_db.c: Added #include <sys/socket.h>.
6382 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6384 * filesys.c (scm_input_waiting_p): use select in preference to
6385 FIONREAD, since the latter doesn't detect EOF.
6386 Throw error if neither select nor FIONREAD available.
6388 * socket.c (scm_connect): take a port, not a fd object.
6389 (scm_fill_sockaddr): throw an error if fam is not recognised.
6390 (scm_bind): use scm_fill_sockaddr.
6391 (scm_listen): take a port, not a fd object.
6392 (scm_accept): take and return a port. return #f in the car if
6393 address can't be got
6394 (scm_sock_fd_to_port): new procedure.
6395 (scm_socket): use scm_sock_fd_to_port.
6396 (scm_addr_vector): throw error if unrecognised address type.
6397 take an extra argument with the calling procedure name.
6398 (scm_getsockname): take a port. return #f if address can't be got.
6399 (scm_getpeername): take a port. return #f if address can't be got.
6400 (scm_recvfrom): take a port. return #f for address component if can't
6402 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6403 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6405 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6407 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6408 use separate data pointers, to allow them to be designed
6409 independently and reused.
6410 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6411 Renamed from catch_body, catch_handler, and uncaught_throw; made
6413 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6415 (scm_catch): Use the above.
6416 (scm_throw): Don't bother printing a message for an uncaught
6417 throw; we establish a default handler in init.
6418 * throw.h (scm_internal_catch): Prototype updated.
6419 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6421 (struct scm_body_thunk_data): New structure, used as data
6422 argument to scm_body_thunk.
6423 * init.c (struct main_func_closure): New structure, packaging up
6424 the data to pass to the user's main function.
6425 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6426 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6427 scm_internal_catch to establish a catch-all handler, using
6428 scm_handle_by_message. This replaces the special-case code in
6430 (invoke_main_func): Body function for scm_internal_catch; invoke
6431 the user's main function, using the main_func_closure pointer to
6432 decide what to pass it.
6433 * root.c (struct cwdr_body_data): Remove handler_proc member.
6434 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6435 (cwdr_handler): Removed.
6437 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6439 * socket.h (SCM_P): update bind prototype.
6440 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6441 include "feature.h".
6442 (scm_socket): return a port, not a file descriptor object.
6443 include "fports.h" and <unistd.h>
6444 (scm_bind): take a port, not a file descriptor object.
6445 take an extra argument for address args.
6447 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6448 INADDR_NONE, INADDR_LOOPBACK.
6450 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6452 * init.c: include net_db.h and not fdsocket.h.
6453 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6455 * Makefile.am: corresponding changes.
6456 * socket.h: renamed from fdsocket.h, fix names.
6457 * net_db.h: renamed from socket.h, fix names.
6458 * socket.c: renamed from fdsocket.c.
6459 remove _sys from procedure names.
6460 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6461 add "socket" to features list.
6462 * net_db.c: renamed from socket.c.
6463 remove _sys from procedure names.
6464 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6465 add "net-db" to features list.
6466 include "net_db.h". don't include <sys/socket.h> or
6469 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6471 * tags.h (scm_tags): Removed comma at end of last enumerator.
6473 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6475 Don't use GCC extensions to allocate space for debugging frames.
6476 (Here he goes again! Why do we put up with this?!)
6477 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6478 an scm_debug_info structure, not an in-line array of them. Add
6479 'info' member, to say how many vect elements we've used, for eval
6481 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6482 a new variable debug_info_end to mark the end of vect, instead of
6483 the address of the 'info' pointer itself.
6484 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6485 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6486 (SCM_APPLY): Explicitly allocate space for debug.vect.
6487 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6488 * stacks.c: Adjusted for new debug frame structure.
6489 (RELOC_INFO, RELOC_FRAME): New macros.
6490 (stack_depth, read_frames): Use them, and new scm_debug_frame
6491 element 'info', instead of magically knowing that eval frames have
6492 an info pointer sitting after vect.
6493 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6495 (scm_init_stacks): Formatting tweaks.
6497 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6499 Give GCC more control flow information, so it can be sure that
6500 variables aren't used uninitialized.
6501 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6502 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6503 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6504 scm_misc_error): Tell GCC that these functions never return.
6505 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6506 out the field type, call abort if SCM_ASSERT returns, to placate
6508 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6509 scm_wta ever returns. We can't handle this case anyway, and this
6510 gives the optimizer more information.
6511 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6512 scm_wta ever returns.
6514 In some cases, the code is fine, but GCC isn't smart enough to
6515 figure that out; this usually happens when one variable is only
6516 initialized and used when a particular condition holds true, and
6517 we know that condition will never change within a given invocation
6518 of the function. In this case, we simply initialize the variables
6519 to placate the compiler, hopefully to a value which will cause a
6520 crash if it is ever actually used.
6521 * print.c (scm_iprin1): Initialize mw_pos.
6522 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6523 * throw.c (scm_ithrow): Initialize dynpair.
6524 * unif.c (scm_uniform_vector_ref): Initialize cra.
6525 * struct.c (init_struct): Initialize prot.
6526 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6528 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6529 if EXPR contains no expressions.
6531 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6533 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6534 cause an infinite loop (???). So much for the algebraic
6535 equivalency of variable-sized arrays and alloca...
6537 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6539 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6540 a SCM boolean, not a C boolean.
6542 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6544 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6545 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6546 rules for raising scm_mtrigger. Previously, unfortunate but not
6547 unlikely circumstances could result in almost constant invokation
6548 of the gc. Now, this situations should be less likely, but they
6549 are not prevented completely.
6551 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6553 * numbers.c (scm_fuck): Procedure removed; looks like old test
6555 * numbers.h: Prototype removed.
6557 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6559 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6560 array to a pointer, to match my Nov 21 change in eval.c.
6562 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6564 * libguile.h: Added #include "libguile/backtrace.h", #include
6565 "libguile/stacks.h".
6567 * strings.c (scm_string scm_make_string scm_string_ref
6568 scm_string_set_x scm_string_equal_p scm_string_append):
6569 Bugfix according to scm patch from Aubrey Jaffer:
6570 Corrected long-standing
6571 (not (eqv? (integer->char 128)
6572 (string-ref (make-string 1 (integer->char 128)) 0)))
6573 bug found by John Kozak <jk@noontide.demon.co.uk>.
6575 * strports.c, strports.h: Make scm_eval_0str return the value of
6576 the last expression evaluated (previously, it returned void).
6578 * strports.c, strports.h: New function: scm_read_0str. Does what
6581 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6583 * simpos.c (scm_getenv): return #f if string can't be found in the
6584 environment instead of throwing an exception, for compatibility
6585 with numerous other systems.
6587 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6589 * Makefile.am (.c.x): Use guile-snarf.
6590 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6592 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6594 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6596 * backtrace.c (scm_display_error_message): Made non-static, and
6597 renamed from display_error_message.
6598 * backtrace.h (scm_display_error_message): Added extern decl.
6599 * throw.c (uncaught_throw): Use it to display the error message.
6601 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6603 * inet_aton.c: Use #if 0, not #ifdef 0.
6605 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6607 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6608 to convert the returned value.
6609 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6610 the offset argument.
6612 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6614 Add new interface to catch/throw, usable from C as well as
6616 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6617 (scm_internal_catch): New function, replaces...
6618 (scm_catch_apply): Deleted.
6619 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6620 mechanism which is a bit more code, but can be used nicely from C
6621 and implement the Scheme semantics as well.
6622 (scm_internal_catch): This is the replacement; it's named after
6623 the analogous function in Emacs.
6624 (scm_catch): Reimplemented in terms of the above.
6625 (struct catch_body_data, catch_body, catch_handler): New
6626 functions, used by scm_catch.
6627 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6628 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6629 support for new cwdr.
6631 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6634 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6636 * acconfig.h: Added DYNAMIC_LINKING symbol.
6637 * configure.in: Add option and checks for dynamic linking.
6638 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6639 dynl.h: New files for dynamic linking support.
6640 * Makefile.am (libguile_a_SOURCES):
6642 (modinclude_HEADERS): Added "dynl.h".
6643 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6645 * init.c (scm_boot_guile_1): Call
6646 scm_init_dynamic_linking to initialize dynamic linking support.
6648 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6650 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6651 (as we Schemers say). It needs to be global, so that I can tweak
6652 it for the proper operation of unexec.
6653 (scm_boot_guile_1_live): New variable, see above.
6655 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6657 * guile-snarf.sh: Removed.
6658 * PLUGIN/guile.libs: Added dependency for -lm.
6659 * acinclude.m4: Renamed from aclocal.m4.
6660 * PLUGIN/greet: Removed.
6661 * Makefile.am, aclocal.m4: New files.
6662 * configure.in: Updated for Automake.
6664 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6666 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6667 and not top_level_lookup_thunk_var.
6669 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6671 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6673 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6675 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6676 Scheme function, instead of syntax. Single argument is now a
6679 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6681 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6682 scm_ra_divide): Properly terminate statements passed as arguments
6683 to IVDEP macros. (Thanks to Bernard Urban.)
6685 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6686 with non-constant sizes. (Thanks to Bernard Urban.)
6688 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6690 It's an "eval closure", not an "eval thunk." A thunk is a
6691 function of no arguments.
6692 * root.h (struct scm_root_state): Renamed
6693 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6694 (scm_top_level_lookup_closure_var): Renamed from
6695 scm_top_level_lookup_thunk_var.
6696 * root.c (mark_root): Uses changed.
6697 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6698 * init.c (scm_start_stack): Uses changed.
6699 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6700 Change scheme-visible name to *top-level-lookup-closure* from
6701 *top-level-lookup-thunk*.
6703 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6705 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6706 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6708 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6710 * gc.c (struct scm_heap_seg_data): Doc fixes.
6712 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6713 sweeping. Then, prepend each segment's free cells to its
6714 freelist, rather than wiping out the old value. (Thanks to Marius
6717 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6718 scm_check_freelist, scm_debug_newcell): New functions and
6719 variables, for debugging freelist problems.
6720 * pairs.h (SCM_NEWCELL): New debugging version added.
6721 * gc.h (scm_debug_newcell): Added extern declaration, used by
6722 debugging version of SCM_NEWCELL.
6724 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6726 On some systems <libc.h> conflicts with <unistd.h>, and should not
6727 be #included at all.
6728 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6729 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6730 * configure.in: Call it.
6731 * posix.c, filesys.c: Use its results to decide whether or not to
6733 * configure, scmconfig.h.in: Rebuilt with autoconf and
6736 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6738 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6739 pointer to the stdio stream before calling scm_setbuf0, so the
6740 latter will be able to retrieve it. I'm surprised this didn't
6741 segfault earlier. (Thanks to Christopher Lee.)
6743 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6745 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6748 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6750 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6751 number of stack narrowing specifier pairs. The first specifier in
6752 a pair controls inner border, the second the outer border. A
6753 number means cut that number of frames, a procedure object means
6754 cut until that object is found in operator position in a frame.
6756 * root.c (cwdr): Bugfix.
6758 * read.c: Recording of positions disabled by default.
6760 * procs.c (scm_closure_p): New function.
6762 * posix.c (scm_tmpnam): New function.
6764 * load.c: Added #include "throw.h".
6765 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6768 * load.c, load.h (scm_read_and_eval_x): New function.
6770 * eval.c: Renamed debug option "deval" to "debug".
6772 (scm_eval_x): `eval!' is no longer accessible from the scheme
6773 level. Motivation: We can't allow operations which introduce
6774 glocs into the scheme level. Guile's type system can't handle
6775 these as data. Use `eval' or `read-and-eval!' as replacement.
6777 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6778 SCM_CONSP since this is a macro!; Set vframe.prev to
6779 scm_last_debug_frame instead of 0. In this way we can look
6780 "above" the virtual start stack frame if we wish.
6781 (scm_debug_hang): New function: Useful for debugging Guile in
6782 certain tricky situations. Will probably be removed later...
6784 * debug.h: Changed semantics of debug option "backtrace". This
6785 option now only indicates whether we want automatic backtrace at
6788 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6790 * ports.c: #include "filesys.h"
6791 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6793 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6794 Motivation: This is system specific code which is related to file
6795 I/O. It also may use select. Added code by Gary Houston to
6796 detect presence of character in stdio buffers.
6798 * libguile.h: #include "libguile/libpath.h"
6800 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6801 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6802 SCM_SITE_DIR; Install libpath.h among the other include files.
6804 * load.c, load.h (scm_sys_package_data_dir): New function.
6806 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6808 * stacks.h: Bugfix: Don't use tail-array length field as stack
6809 length field! This screwed GC.
6811 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6813 * _scm.h: Added #ifndef around definition of macros min and max.
6815 * __scm.h: Added hooks for threads to plugin to in ints protection
6816 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6817 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6818 the main code in these macros duplicated and spread over multiple
6819 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6820 SCM_THREAD_SWITCHING_CODE.
6822 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6824 * snarf.h: New file.
6825 * guile-snarf.sh: New file.
6826 * Makefile.in (inner_h_files): Added snarf.h
6827 (ancillary, install, uninstall, distclean): Added actions for
6829 (.c.x): Use guile-snarf.
6830 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6831 (gen_c_files): Note that these depend on guile-snarf.
6832 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6833 now in "snarf.h". Added #include "snarf.h" to get them.
6834 * libguile.h: Added #include "snarf.h".
6835 (Patches applied and tweaked by Jim Blandy.)
6837 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6839 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6840 standards suggest against providing prototypes for system
6841 functions. Thanks to Greg Troxel.
6843 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6845 * strports.c (scm_eval_0str): New function.
6846 #include "read.h", to get prototype for scm_read.
6847 * Makefile.in (strports.o): Update dependencies.
6848 * strports.h: New prototype.
6850 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6851 scheme name from "int?" to "integer?". It seems to do the job.
6852 * numbers.h: Rename prototype too.
6853 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6856 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6857 scm_num_eq_p): Rename these according to R4RS conventions: call
6858 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6859 to making libguile R4RS compliant without ice-9...
6861 * load.c (scm_sys_search_load_path): Search for files under all
6862 extensions listed in the %load-extensions variable. If FILENAME
6863 is absolute, return it unchanged, without searching the load path.
6864 (scm_loc_load_extensions): New variable, pointing to
6865 %load-extensions' value cell.
6866 (scm_init_load): Initialize it, and the value it points to.
6867 (scm_primitive_load_path): Improve error reporting.
6869 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6870 of new Scheme variable %load-hook.
6871 (scm_primitive_load): Apply %load-hook to filename.
6873 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6875 * configure.in: add tests for figuring out whether buffered data
6876 is available in a FILE structure, which is needed by char-ready.
6878 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6881 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6882 exceptions using misc_error instead of syserror. It seems a bit
6883 odd to throw an exception if a string can't be found in the
6884 environment, but it's consistent with open-file, stat etc.
6885 (simpos.h): remove sys_ from getenv.
6887 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6888 occurs, throw an error instead of returning errno. Return value
6890 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6892 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6894 * filesys.c (scm_stat2scm): derive file type and permissions from
6895 the stat mode and append them to the returned vector.
6896 There isn't much overhead in doing this and it avoids the need to
6897 work with S_IRUSR et al. in Scheme.
6898 Define symbols scm_sym_regular etc.
6899 (scm_init_filesys): don't intern S_IRUSR etc.
6901 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6902 and s_primitive_load_path.
6904 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6906 * error.h: don't declare error symbols. prototype for scm_misc_error.
6908 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6911 * error.c: use SCM_SYMBOL to set up error keys.
6912 scm_misc_error: new procedure.
6914 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6916 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6917 between `#!' and `!#' is ignored.
6918 (skip_scsh_block_comment): New function.
6920 * feature.c (scm_set_program_arguments): New argument, FIRST.
6921 * feature.h: Update prototype.
6922 * init.c (scm_boot_guile_1): Pass new argument to
6923 scm_set_program_arguments.
6925 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6927 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6928 (scm_boot_guile): Call scm_set_program_arguments here, later than
6929 the old initialization.
6931 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6932 initialization procedure.
6933 - Delete in, out, err arguments; there are other perfectly good
6934 ways to override these when desired.
6935 - Delete result argument; this function shouldn't ever return.
6936 - Rename init_func argument to main_func, for less confusion.
6937 - Delete boot_cmd argument; main_func is more general.
6938 -Add 'closure' argument, to help people pass data to main_func
6939 without resorting to global variables.
6940 - Abort if reentered; don't bother returning an error code.
6941 - Call scm_init_standard_ports to set up the default/current
6942 standard ports; no need to pass them to scm_start_stack.
6943 - Remove code to evaluate the boot_cmd, and start the repl; let
6944 the user do something like that in main_func if they want.
6945 - Remove code to package up a return value; main_func can do any
6947 - Call exit (0), instead of returning.
6948 (scm_start_stack): Don't initialize the I/O ports here; that's
6949 weird. Delete in, out, err arguments. Move guts to
6950 scm_init_standard_ports, scm_stdio_to_port.
6951 (scm_init_standard_ports): New function, to set up current and
6952 default standard ports.
6953 (scm_start_stack, scm_restart_stack): Make these static.
6954 * init.h (scm_boot_guile): Adjust declaration.
6955 (scm_start_stack, scm_restart_stack): Remove externally
6956 visible declarations for these.
6957 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6959 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6960 written out several times in scm_start_stack.
6961 * fports.h: New declaration for the above.
6963 * feature.c (scm_set_program_arguments): New function.
6964 * feature.h: New declaration for the above.
6966 * ports.c: Formatting tweak.
6968 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6970 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6971 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6972 for obtaining the address of a car or cdr field. Motivation:
6973 &SCM_CXR make assumptions about the internal structure of the
6976 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6977 Motivation: see SCM_CXRLOC.
6979 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6980 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6981 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6982 Motivation: Safer use. Some other macros are defined in terms of
6983 these operations. If these are defined using the SCM_SETCXR
6984 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6985 to inefficiency and an <e1> with side-effects could potentially
6986 break. Also, these particular operations are heavily utilized in
6987 the garbage collector. In unoptimized code there will be a
6990 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6991 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6992 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6993 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,

6995 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6996 vports.c: Cleaned up use of pairs: Don't make any special
6997 assumptions about the internal structure of selectors and
6998 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6999 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
7000 (Among other things, this change makes it easier to build Guile
7001 with certain compilers which have problems with casted lvalues.)
7003 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7005 * stacks.c: Improve selection of relevant stack frames when making
7006 a stack object. Introduce one level of indirection in the stack
7007 object to make it possible to "narrow" to a certain region of the
7008 stack. This facilitates making use of more clever algorithms (not
7009 implemented) for selecting relevant frames and gives a cleaner
7010 design since selection of frames can be done independently of
7011 extraction of frames from the real stack.
7012 (scm_stack_id): Also take #t as argument which means look at
7015 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
7016 Turn n_tail into an integer directly representing current number
7017 of frames in stack. Add field tail.
7019 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
7021 * debug.c (scm_make_memoized): Made it available at scheme level.
7022 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
7023 SCM_NIMP before applying heavier predicates in argument checking.
7024 (scm_local_eval): Also take memoized object as argument.
7026 * backtrace.c (scm_display_error): Just a safety measure: Stacks
7027 aren't created with zero length, but should such a strange
7028 creature suddenly turn up...
7030 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
7032 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
7033 `del', for the sake of C++ compilers. (Patch applied by JimB.)
7035 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
7037 * variable.c (scm_make_variable): Make the name hint optional, as
7039 (anonymous_variable_sym): Renamed from variable_sym. All uses
7042 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7043 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7044 of scm_primitive_load_path was also changed to
7045 "primitive-load-path", from "%try-load-path". Callers changed.
7046 We'd like to respect the convention that a function named
7047 "try-mumble" should behave just like the function called "mumble",
7048 but return #f instead of signalling some error.
7049 * load.h: Rename prototypes.
7051 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7053 * print.c (make_print_state, grow_print_state), print.h: Modified
7054 the print state representation: Don't use a tail array for
7055 recording of circular references. Resizing of the print state
7056 structure invalidates the print state pointer. To avoid passing
7057 around an indirect print state reference to all printing
7058 functions, we instead let the print state reference a resizable
7061 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7063 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7064 Don't crash when passed an improper list terminated by a
7065 non-immediate value.
7067 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7069 Allocate data for structures on an eight-byte boundary, as
7070 required by the tagging system.
7071 * struct.c (alloc_struct): New function.
7072 (scm_make_struct, scm_make_vtable_vtable): Call it.
7073 * struct.h (scm_struct_n_extra_words): Bump to 3.
7074 (scm_struct_i_ptr): New "field".
7075 * gc.c (scm_gc_sweep): When we need to free the data, use the
7076 information stored by alloc_struct to find the beginning of the
7077 block allocated to the structure, so we can free it.
7079 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7081 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7084 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7085 (scm_debug_info): New member: id.
7087 * stacks.c: Stacks are now represented as structs; Stacks have an
7088 id given to them by `start-stack'.
7089 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7091 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7092 Changed stack representation.
7094 * debug.c (scm_procedure_name): Try procedure property `name' for
7095 compiled closures aswell.
7097 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7099 * eval.c: scm_i_name moved to gsubr.c
7100 (scm_m_define): Record names of all kinds of procedure
7101 objects. (Earlier, only closures were recorded.)
7103 * procprop.h: Added declaration of scm_i_name.
7105 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7106 (scm_make_gsubr): Record names of compiled closures.
7108 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7110 * debug.c, debug.h: Removed obsolete code.
7112 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7113 stacks.c: Renamed regs --> scm_contregs.
7115 * print.c (scm_free_print_state): Cleanup print state before
7116 returning it to pool. It is better to do it here than in
7117 scm_prin1 since scm_prin1 is called often.
7119 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7120 s_set_source_property_x): Check that first argument is a pair or a
7123 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7124 scm_i_line, scm_i_column and scm_i_breakpoint global.
7126 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7127 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7130 * debug.h: Added debug object smob declaration and macro
7133 * configure.in: Build with backtrace.o and stacks.o if debug
7136 * Makefile.in: Added entries for new files: backtrace.c,
7137 backtrace.h, stacks.c and stacks.h.
7139 * symbols.c (scm_sym2ovcell): Fixed documentation.
7141 * _scm.h (min, max): Added.
7143 * async.c: Moved `min' macro to _scm.h.
7145 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7146 SCM_BACKTRACE_INDENT.
7148 * eval.c: Added new debug options `maxdepth' and `indent'.
7150 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7152 * print.h: Added selector SCM_PRINT_STATE.
7154 * print.c: New functions: scm_make_print_state,
7155 scm_free_print_state.
7157 * print.h: Added declarations for scm_make_print_state,
7158 scm_free_print_state.
7160 * debug.c (scm_m_start_stack): New acro.
7162 * debug.h: Small cleanup.
7164 * init.c (scm_boot_guile_1): Moved scm_init_debug below
7167 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

7189 declare functions with prototypes. (Patch thanks to Marius
7192 More prototype-related changes from Marius Vollmer:
7193 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7194 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7195 * ports.h (ptobfuns): Added prototypes. This means some casting in
7197 * fports.c: Added casts for initializations, since the functions
7198 are defined to take FILE * as their stream argument, not SCM.
7199 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7200 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7201 to `char *str_data' to conform to prototype.
7203 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7205 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7207 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7209 * stime.c, stime.h: use SCM_P method.
7211 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7213 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7214 be given at least two arguments. Insist that lst's last element
7215 be a list, but don't make any requirements of its predecessors.
7217 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7219 * eval.c (scm_nconc2last): Revert last change; there seems to be
7220 other stuff going on here.
7222 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7224 * eval.c (scm_nconc2last): Make sure that each element of lst
7225 (which is a list of argument lists, except for the tail) is a
7226 proper list, i.e., finite and terminated by '().
7228 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7230 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7233 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7234 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7237 * vectors.c (scm_make_vector): Fill vectors with the undefined
7238 value, to help make Guile Scheme code more portable to other
7241 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7242 * symbols.h, tags.h: Doc fixes.
7244 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7246 * async.c (scm_take_signal): Doc fixes.
7248 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7250 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7251 want to subtract it from the modulus; we just want to leave it
7254 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7256 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7259 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7261 * throw.c (scm_catch_apply): Finished implementation of
7264 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7266 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7268 (scm_init_filesys): set "i/o-extensions" feature.
7271 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7273 * Makefile.in (root.o): Correct dependencies.
7275 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7277 * Makefile.in: Added dependency entry for root.o.
7279 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7280 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7282 * init.c (scm_start_stack): Set initial root continuation number
7285 * procs.c: New function: scm_thunk_p.
7287 * procs.h: Added declarations of scm_thunk_p.
7289 * root.c: Renamed `call-with-new-root' -->
7290 `call-with-dynamic-root'.
7291 (cwdr): Removed allocation of new root state. This should be done
7292 separately by use of scm_make_root.
7293 (scm_apply_with_dynamic_root): New function: Does what it
7294 sounds like. Needed when spawning threads.
7296 * root.h: Added member last_debug_frame to root state.
7297 Added #include "libguile/debug.h"
7299 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7300 arguments. The motivation is that code in root.c needs catch
7301 functionality, and we want to avoid code duplication.
7302 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7303 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7304 handlers that run without popping the stack into the dynwind
7307 * throw.h: Added prototypes for scm_catch_apply and
7310 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7312 * root.h (scm_root, scm_set_root): Decouple thread support details
7313 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7314 SCM_SET_THREAD_LOCAL_DATA.
7316 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7317 and tortoise scanning loop.
7319 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7321 * Makefile.in: Rebuild dependencies.
7323 * libguile.h: #include "libguile/print.h" before "smob.h", since
7324 the latter uses the print_state structure.
7326 * throw.c (scm_ithrow): Use the correct variable when checking to
7327 see if a given element of scm_dynwinds is a valid catch.
7329 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7330 structure, abort; don't just silently ignore the garbage.
7332 * _scm.h: #include "print.h" here, since it seems to be used just
7334 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7335 strports.c, unif.h: Don't #include "print.h".
7337 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7339 * feature.h (scm_loc_features): Removed external declaration.
7340 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7342 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7344 * feature.c (scm_init_feature): Added threads feature (needs to be
7345 initialized here, since features doesn't exist when
7346 scm_init_threads is called).
7348 * libguile.h: Added #include "libguile/../threads/threads.h".
7349 (This is a kludge to get thread support working. This should be
7352 * configure.in, acconfig.h: Added flags for thread support.
7354 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7357 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7358 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7361 * _scm.h: Added conditional #include "threads.h"
7363 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7364 SCM_THREADS_SWITCHING_CODE.
7366 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7367 allocate the basic dynamic root object.
7368 (scm_boot_guile): Added call to scm_init_root.
7370 * root.c, root.h: Added root smob.
7371 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7372 functions: Implements dynamic roots mostly according to spec in
7373 SCM manual. Main difference is that the second argument is a
7374 throw handler rather than an error "thunk".
7376 * root.h: Added declaration of scm_init_root.
7378 * root.c: Added #include "genio.h", #include "smob.h", #include
7379 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7381 (scm_init_root): Added #include "root.x".
7383 * throw.c: Added #include "stackchk.h"
7384 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7385 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7386 can be used in scm_call_with_new_root; Added reenabling of stack
7387 checking when catching a throw.
7389 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7391 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7393 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7394 element is not found, as per R4RS.
7396 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7398 * list.c: Doc fixes throughout.
7400 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7402 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7403 declare the char * to be const. Avoids a warning in rgx.c.
7405 * ports.h: spelling fix.
7407 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7410 * load.c (scm_sys_try_load_path): throw an error if file not found
7411 (like it says it in NEWS).
7413 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7415 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7416 PROPS slot to '(), not #f; it's an empty alist.
7418 * throw.h, throw.c: Use SCM_P instead of #if hair.
7420 Remove special support for uncaught throws; see throw.c for
7422 * throw.c (uncaught_throw): New function.
7423 (scm_ithrow): Call uncaught_throw if we don't find a throw
7424 target; don't mess with scm_bad_throw_vcell.
7425 (scm_bad_throw_vcell): Variable deleted.
7426 (scm_init_throw): Don't initialize it.
7428 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7431 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7433 * numbers.c (scm_istr2int): If the number is short (as most
7434 numbers are), just call scm_small_istr2int to deal with it.
7435 (scm_small_istr2int): New function, created by un-#ifdefing the
7436 non-bignum version of scm_istr2int and renaming it.
7438 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7440 * load.c (scm_sys_try_load): don't check whether value returned
7441 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7442 Change the Scheme name from %try-load to primitive-load.
7444 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7445 Can avoid passing a message, allowing it to be derived in the
7446 error handler (e.g., if we want to throw to the key both from
7449 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7451 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7452 references now have a new appearance which is more compact and
7453 also gives a clue about what the target of the reference is.
7454 By setting parameters in the print state, more fancy printing can
7455 be achieved. This is used by the (not yet commited) backtrace
7458 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7460 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7463 * print.c: Added #include "struct.h". Removed function
7466 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7467 scm_iprin1. Removed prototype for scm_prlist.
7469 * arbiters.c (prinarb),
7470 async.c (print_async),
7471 debug.c (prindebugobj, prinmemoized),
7472 eval.c (prinprom, prinmacro),
7473 filesys.c (scm_fd_print, scm_dir_print),
7475 mallocs.c (prinmalloc),
7476 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7477 smob.h (scm_smobfuns),
7478 srcprop.c (prinsrcprops),
7480 unif.c, unif.h (scm_raprin1, rapr1),
7481 variable.c (prin_var): Changed argument `int writing' to
7482 `scm_print_state *pstate'.
7484 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7485 that it will be called before scm_init_print.
7487 * print.c (scm_prin1): Print states are now allocated when calling
7488 scm_prin1 and then passed around to all printing functions as an
7489 argument. A cache `print_state_pool' enables reuse of print
7491 (scm_make_print_state): New function.
7492 (scm_iprin1): Adaption to print states.
7493 (scm_iprlist): An initial "hare and tortoise" scan brings down
7494 time complexity to O (depth * N). (Better time complexity will be
7495 achieved when the printing code is completely rewritten.)
7497 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7499 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7500 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7501 it gets done whether or not the cache variable has a value.
7503 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7505 Distinguish #f and ().
7506 * __scm.h: #undef SICP.
7507 * pairs.h (SCM_EOL): Delete this definition, equating it with
7509 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7510 the value it used to have. Doc fixes, too.
7512 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7514 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7515 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7516 Lord's implementation of structs, allowing for tail arrays as
7517 described in the manual. Also fixed some bugs. (Both the interface
7518 and the implementation should be improved.)
7520 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7522 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7523 People who whish to see the source can do `(print-enable 'source)'.
7524 Removed #ifdef DEBUG_EXTENSIONS.
7526 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7528 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7529 integer (assuming for now accepting an integer is a good thing).
7531 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7532 %S will be used instead for write'ing arguments.
7534 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7535 asserts. fix a few other asserts.
7536 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7537 scm_uniform_vector_ref, scm_array_set_x,
7538 scm_dimensions_to_unform_array): change args in
7539 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7540 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7541 scm_substring_fill_x): likewise.
7542 gsubr.c (scm_gsubr_apply): likewise.
7543 eval.c (SCM_APPLY): likewise.
7545 * eval.c (4 places): replace scm_everr with lgh_error or
7548 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7549 scm_memory_error): new procedures.
7550 scm_everr: deleted. can use scm_wta, dropping first two args.
7551 scm_error: convert NULL subr to SCM_BOOL_F.
7553 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7556 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7559 * error.c, error.h: new error keys: scm_arg_type_key,
7560 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7562 scm_wta: reimplement using lgh_error instead of scm_everr.
7564 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7566 * gdbint.c: scm_lread now has one more argument.
7568 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7569 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7570 loading source from non-file ports, which, e. g., happens when
7571 using the Emacs interface).
7573 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7576 * read.c: Added code for recording of positions of source code
7577 expressions; New functions: recsexpr, scm_lreadrecparen;
7578 _scm_make_srcprops --> scm_make_srcprops
7579 (scm_flush_ws): Removed updating of positions counters. This work
7580 is already done by scm_gen_getc
7582 * read.h: Added prototype for scm_lreadrecparen
7584 * print.c: Added #include "alist.h"
7586 * eval.c: Added #include "hash.h"
7588 * eq.c: Added #include "ramap.h"
7590 * options.c: Documentation fixes.
7592 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7593 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7594 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7595 --> scm_make_srcprops
7597 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7598 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7599 function calls in the definition of the whash access macros.
7601 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7603 * init.c (scm_boot_guile): Add level of indirection to
7604 scm_boot_guile_1() to ensure that stack base pointer is properly
7605 initialized. There was no guarantee that variable i was the
7606 highest/lowest variable on stack (i.e. the call frame of
7607 scm_boot_guile was not completely protected from gc).
7609 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7611 * ports.h (scm_port_table): put back file_name, it will be used to
7612 support debugging. Undo related changes in fports.c, ioext.c,
7615 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7617 * ports.h (scm_port_table): remove file_name member for now, it seems
7619 * fports.c (scm_open_file): don't set file_name in PTAB.
7620 (prinfport): don't use file_name in PTAB.
7621 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7622 * ports.c (scm_add_to_port_table): don't intialize file_name.
7623 (scm_port_file_name): remove for now.
7624 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7626 * fports.h (scm_mkfile): prototype deleted.
7627 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7629 * debug.c, unif.c: use scm_out_of_range instead of
7630 wta for range errors (ASSERT still needs work).
7632 * error.c, error.h (scm_out_of_range): new procedure.
7634 * error.c, error.h (scm_out_of_range_key): new key.
7636 * posix.c (scm_sync): #else was missing.
7638 * error.c, error.h: append _key to names scm_num_overflow and
7641 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7642 of consing an empty list.
7643 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7644 of macros, saves code and string space.
7645 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7646 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7647 lower case. Rename scm_syserror_m to scm_syserror_msg.
7648 error.h: prototypes for new procedures.
7650 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7652 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7654 * error.c, error.h: setup scm_num_overflow key.
7656 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7657 Remove definition of SCM_OVSCM_FLOW.
7659 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7661 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7662 explicit message and args.
7664 * error.c, error.h, __scm.h: change system_error_sym to
7667 * error.c (system_error_sym): remove leading %% from the Scheme name
7670 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7672 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7674 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7675 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7676 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7677 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7678 renamed. (These were introduced by unsupervised name
7681 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7683 * print.c: Added code for detection of circular references during
7684 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7685 a hook for printing of closures (accessible via print options).
7686 This leads to a split of calls to scm_iprin1 into two classes:
7687 elementary print operations (e. g. the code which prints a smob)
7688 still use scm_iprin1 while top level calls (like scm_display) use
7689 scm_prin1. scm_prin1 begins by clearing the data structure used
7690 to record reference information.
7692 * print.h: Added declarations of scm_prin1 and scm_prlist.
7694 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7696 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7698 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7700 * error.c (err_head): scm_iprin1 --> scm_prin1
7702 * debug.c: Adjusted header comment.
7706 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7708 * strerror.c: Doc fix.
7710 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7712 * gdbint.c (gdb_read): Now possible to run during GC.
7713 (unmark_port, remark_port): New functions.
7715 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7717 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7718 of allocating a new string object. Also, increase size by
7719 the factor 2 instead of 1.5.
7721 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7723 * __scm.h (SCM_P): Corrected to run under traditional C.
7725 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7728 * async.c: Calls to scm_sysintern corrected.
7730 * async.h (scm_async_clock): Redundant declaration removed.
7732 * continuations.c (scm_dynthrow): Redundant declaration removed.
7734 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7735 Definition typos corrected.
7737 * debug.h: Missing declarations of functions in debug.c added
7740 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7741 Missing declarations to functions in eval.c added.
7743 * filesys.c: Possibly uninitialized variable rv.
7745 * gc.h (scm_object_addr, scm_unhash_name): Missing
7746 declarations of functions defined in gc.c added.
7748 * genio.c: Possible typos str_data -> wstr_data. ???
7750 * genio.c: Possibly unintended shadowing of local variable
7751 `int c' (gotos out of scope of inner `c'). ???
7753 * init.c: Uninitialized `SCM last' may be used.
7755 * ioext.h: (scm_sys_isatty_p): Typo.
7757 * list.h (scm_list_head): Missing prototype for function in
7760 * numbers.c (scm_two_doubles): Changed from extern to static
7761 (is used only within numbers.c).
7763 * numbers.h: Repeated declarations removed.
7765 * ports.h (scm_close_all_ports_except): Declaration for the
7766 function defined in ports.c added.
7768 * posix.h: Missing declarations added.
7770 * procs.h (scm_make_subr_opt): Missing declaration added.
7772 * socket.h (scm_sys_gethost): Missing declaration added.
7774 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7776 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7777 Missing declarations added.
7779 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7781 * struct.c: Uninitialized variable `SCM answer' may be used.
7783 * unif.c (l2ra): Declaration prototype.
7785 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7786 defined in ramap.c).
7788 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7789 Redundant declarations removed (they are in ramap.h).
7791 * variable.h (scm_make_udvariable,
7792 scm_make_undefined_variable): Declaration corrected to
7793 correspond variable.c.
7795 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7796 Missing declarations added.
7798 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7800 * Makefile.in (distclean): Don't forget to delete fd.h.
7802 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7804 * fd.h.in, tags.h: Trivial cleanups.
7806 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7807 marksweep.h just declared functions from gc.c.
7808 * gc.h, libguile.h: Don't #include "marksweep.h".
7809 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7810 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7811 dependencies updated.
7813 * libguile.h: Don't #include "files.h"; it's been deleted.
7815 * files.c (scm_sys_delete_file): Moved to filesys.c.
7816 File is now empty; deleted.
7818 * filesys.c: scm_sys_delete_file is now here. Remove
7819 #if's; they seem to rely on remnants of an old portability
7820 regimen. If the problems come up again, solve them properly,
7821 using autoconf. Specifically: Don't test M_SYSV, and #define
7822 remove to be unlink if it's #defined; don't use remove just
7823 because HAVE_STDC_HEADERS is #defined.
7824 * filesys.h: Add declarations for scm_sys_delete_file.
7825 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7826 files.o, files.h, files.c, and files.x.
7827 * init.c: Don't #include "files.h", and don't call scm_init_files.
7829 Use SCM_P instead of PROTO; the latter intrudes on the user's
7831 * params.h: Deleted; definition of SCM_P moved to...
7832 * __scm.h: ... here, where it replaces PROTO macro.
7833 * libguile.h, smob.h: Don't #include "params.h".
7834 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7835 smob.h: Fix prototypes accordingly.
7836 * Makefile.in: Update dependencies.
7837 (inner_h_files): Remove params.h.
7839 * gc.c: #include "gc.h"; every module should include its header,
7840 to let the compiler cross-check the declarations against the
7843 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7844 simpos.h: #include "libguile/__scm.h".
7846 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7848 * init.c: Don't forget to #include smob.h and init.h.
7849 * Makefile.in: Dependencies updated.
7851 * smob.h: Use PROTO instead of #if __STDC__.
7853 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7855 * __scm.h: Doc fixes.
7857 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7858 <angles>; this allows `make depends' to work properly.
7860 * libguile.h: #include smob.h and pairs.h before the others; they
7861 define typedefs used by other headers.
7863 C files should #include only the header files they need, not
7864 libguile.h (which #includes all the header files); the pointless
7865 recompilation was wasting my time.
7866 * Makefile.in (all .o dependency lists): Regenerated.
7867 * libguile.h: Don't try to get a definition for size_t here...
7868 * __scm.h: Do it here.
7869 * _scm.h: Since this is the internal libguile header, put things
7870 here that all (or a majority) of the libguile files will want.
7871 Don't #include <libguile.h> here; that generates dependencies on
7872 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7873 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7874 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

7970 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
7971 * weaks.c: Get "weaks.h".
7973 * stackchk.h: #include "libguile/debug.h",
7975 * print.h, read.h: #include "options.h", since everyone who uses
7976 either of these files will need that.
7978 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7979 anyone who uses this file will need them to define the smob
7980 printing functions. Also, get markers.h, since people will need
7981 to #define the mark functions.
7983 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7984 * ports.h: ... to here.
7986 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7987 don't rely on archaic C default type rules.
7989 * fports.h: #include "libguile/ports.h", since you need that in
7990 order to parse this.
7992 * genio.h: #include "libguile/print.h", because you need that to
7993 parse this; don't bother #including "ports.h", since print.h gets
7996 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7998 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7999 this; it's now a reference to an element of *scm_root.
8001 * debug.h: Don't #include "options.h"; the compiler won't be able
8002 to find that once the headers are installed; instead, #include
8003 "libguile/options.h".
8004 * gc.h: Same, with marksweep.h.
8005 * mbstrings.h: Same, with symbols.h.
8006 * scmhob.h: Same, with _scm.h.
8007 * smob.h: Same, with params.h.
8009 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
8010 C files; there's no need for this, and it forces recompilations
8013 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
8015 * error.c (scm_error): declare scm_error_callback.
8017 * error.h: prototype for scm_error_callback.
8019 * __scm.h: define lgh_error.
8020 (SCM_SYSERROR): redefine using lgh_error.
8022 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
8024 * error.c (scm_error): new procedure.
8026 * error.h: prototype for scm_error.
8028 * Makefile.in (install): install scmconfig.h from the current
8029 directory, not $(srcdir).
8031 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8033 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8034 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8035 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
8036 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
8037 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
8038 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8039 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8040 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8041 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8042 vports.h, weaks.h: #include "libguile/__scm.h", not
8043 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
8044 dependencies are within libguile properly.
8046 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8048 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8049 when scmconfig.h doesn't exist.
8051 * load.c (scm_sys_try_load): Correct spelling.
8053 * feature.c (scm_loc_features): Make this static.
8055 * Makefile.in (libpath.h): Omit trailing slash from path. We
8056 shouldn't require it of users, so why put it here?
8058 Move code to initialize and search %load-path from ice-9 to C
8059 code, so we can use the load-path to find the ice-9 boot code;
8060 this makes it easier to run Guile without installing it. See
8061 corresponding changes in guile/Makefile.in.
8062 * feature.c: Move stuff concerned with the load path to load.c.
8063 (scm_compiled_library_path): Deleted.
8064 Don't #include libpath.h here.
8065 * feature.h: Don't mention scm_compiled_library_path.
8066 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8067 <sys/stat.h>, and <unistd.h> (if present).
8068 (R_OK): #define if the system hasn't deigned to.
8069 (scm_loc_load_path): New variable.
8070 (scm_init_load_path, scm_sys_search_load_path,
8071 scm_sys_try_load_path): New functions.
8072 (scm_init_load): Initialize scm_loc_load_path to point to the
8073 value cell of the Scheme %load-path variable.
8074 * load.h: Add declarations for scm_sys_search_load_path,
8075 scm_sys_try_load_path.
8076 * init.c: Call scm_init_load_path.
8077 * Makefile.in (feature.o, load.o): Dependencies updated.
8079 * load.c, load.h: Rewrite using PROTO macro.
8081 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8083 * gc.c (scm_cellp): New function: C predicate to determine if an
8084 SCM value can be regarded as a pointer to a cell on the heap.
8086 * gc.h: Added declaration of scm_cellp.
8088 * gdb_interface.h: New file: The GDB interface header from the GDB
8091 * gdbint.c: New file: GDB interface.
8093 * gdbint.h: New file: GDB interface.
8095 * libguile.h: Added #include <libguile/gdbint.h>.
8097 * init.c (scm_boot_guile): Added scm_init_gdbint.
8099 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8100 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8101 found if object files and source are kept separate).
8103 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8105 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8107 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8109 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8110 TK_SRC_DIR; they're not relevant any more.
8112 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8113 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8115 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8117 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8118 search path, so we can find the <libguile/MUMBLE.h> headers.
8120 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8122 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8123 implicit in the .c.o rule.
8124 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8127 Put the library path in a header file, instead of passing it on
8128 the command line in every compilation.
8129 * Makefile.in (libpath.h): New target.
8130 (feature.o): Depend on libpath.h.
8131 (clean): Delete libpath.h.
8132 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8133 * feature.c: ... #include "libpath.h" here.
8134 * .cvsignore: Ignore libpath.h.
8136 Don't install the unwashed masses of Guile header files in the
8137 main #include path; put most of them in a subdirectory called
8138 'libguile'. This avoids naming conflicts between Guile header
8139 files and system header files (of which there were a few).
8140 * Makefile.in (pkgincludedir): Deleted.
8141 (innerincludedir): New variable; this and $(includedir) are enough.
8142 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8143 (installed_h_files): Divide this up. Now this variable lists
8144 those header files which should go into $(includedir) (i.e. appear
8145 directly in the #include path), and ...
8146 (inner_h_files): ... this new variable says which files appear in
8147 a subdirectory, and are referred to as <libguile/mumble.h>.
8148 (h_files): List them both.
8149 (install): Create innerincludedir, not pkgincludedir. Put
8150 the installed_h_files and inner_h_files in their proper places.
8151 (uninstall): Corresponding changes.
8152 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8153 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8154 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8155 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8156 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8157 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8158 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8159 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8160 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8161 vports.h, weaks.h: Find __scm.h in its new location.
8162 * __scm.h: Find scmconfig.h and tags.h in their new locations
8163 (they're both "inner" files).
8165 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8167 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8169 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8171 * posix.c: Doc fixes.
8173 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8175 * socket.c: Don't include a prototype for inet_aton; just use a
8176 K&R style declaration, to avoid warnings but minimize the chance
8177 of conflicts with the system.
8179 On NextStep, <utime.h> doesn't define struct utime, unless we
8180 #define _POSIX_SOURCE before #including it.
8181 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8182 * acconfig.h: New comment text for above CPP symbol.
8183 * configure.in: Call it.
8184 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8186 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8188 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8189 testing for __EMX__.
8191 * posix.c: #include <libc.h>, if it exists.
8193 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8194 don't even know if the latter exists.
8196 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8197 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8198 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8200 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8202 (scm_init_posix): Use them when initializing the Scheme constants
8205 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8207 * Makefile.in (libdir, includedir, bindir): Use the
8208 autoconf-supplied values, instead of deriving them ourselves.
8209 (pkgincludedir, datadir, pkgdatadir): New variables.
8210 (install, uninstall): Put the header files in a special
8211 subdirectory, not in the main search path.
8213 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8214 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8216 * Makefile.in (IMPLPATH): Deleted; never used.
8218 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8219 on the Tcl/Tk source any more.
8220 (INCLUDE_CFLAGS): Remove references to the above.
8222 * Makefile.in (version.o): Corrected dependencies.
8224 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8226 * libguile.h: #include "version.h"
8228 * init.c (scm_boot_guile): Call scm_init_version.
8229 * gscm.c (gscm_run_scm): Call scm_init_version.
8231 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8232 GUILE_VERSION): AC_DEFINE these.
8233 (acconfig.h): #undef the above symbols.
8235 * Makefile.in (libobjs): Add version.o.
8236 (installed_h_files): Add version.h.
8237 (c_files): Add version.c.
8238 (gen_c_files): Add version.x.
8239 (version.o): New rule.
8240 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,

8250 weaks.o): Add version.h to dependency lists.
8251 (markers.o): Remove duplicate rule.
8253 * version.h: New file.
8255 * version.c: New file.
8257 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8259 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8260 array; use it appropriately. Since GCC is quite happy to
8261 subscript functions, it never warned us about this; we should use
8262 -Wpointer-arith in the future. I guess we never tested
8265 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8267 * socket.c: Doc and copyright fixes.
8269 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8271 * debug.c: Fixed and improved gdb support.
8273 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8275 * socket.c: Added declaration of inet_aton to avoid compiler
8276 warning. (Hope this solution is correct.)
8278 * stime.c: Added declaration of ftime. (This is missing in
8281 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8283 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8285 * Makefile.in (c_files): add strerror.c.
8287 * strerror.c: new file from Emacs' sysdep.c.
8288 maybe configure should also check for sys_errlist.
8290 * configure.in (AC_REPLACE_FUNCS): add strerror.
8292 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8294 * debug.c (scm_init_debug): Added initialization for
8295 scm_evaluator_traps.
8297 * debug.h, debug.c: Various name changes.
8298 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8299 "debug-options-interface". See commentary in options.c.
8301 * options.h, options.c: Options now have documentation strings.
8302 Also added a long explanatory commentary.
8304 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8307 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8308 last_debug_info_frame is now updated in all cases.
8310 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8313 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8315 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8316 Added option STACK_CHECKING.
8318 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8320 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8322 * __scm.h: Removed symbols for debugging support.
8324 * acconfig.h: Added symbols for debugging support.
8326 * configure.in: Added user option for debugging support.
8327 --enable-debug will include the debugging code into libguile.a.
8329 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8330 scm_relocate_chunk_to_heap.
8332 * debug.c: New file: low-level debugging support. It also
8333 includes support for debugging with gdb. (The extensions to gdb
8334 are written by Per Bothner at Cygnus.)
8336 * debug.h: New file: low-level debugging support.
8338 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8339 argument pairs. Extensive modifications to the debugging
8340 evaluator. Added "SECTION:" commentaries to clarify what happens
8341 when, during double compilation. Renamed EVALIMP --> EVALIM.
8342 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8343 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8344 the beginning of the file. New procedure: scm_unmemocopy.
8345 Added some global state variables needed by the debugging
8346 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8347 check_entry, check_apply, check_exit, debug_options and
8348 evaluator_traps. New acro: undefine.
8350 * eval.h: Renamed EVAL --> XEVAL.
8352 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8353 --> scm_make_weak_key_hash_table.
8355 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8356 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8358 * libguile.h: Conditionally include debug.h
8360 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8361 scm_object_properties shouldn't return handle. `handle' now gets
8362 initialized in scm_set_object_properties_x. scm_object_properties
8363 doesn't any longer create an entry in scm_object_whash.
8365 * options.c: New file: handling of run time options.
8367 * options.h: New file: handling of run time options.
8369 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
8371 * print.c: New procedure: scm_print_options
8373 * print.h: Defines for print options.
8375 * read.c: New procedure: scm_read_options
8377 * read.h: Defines for reader options.
8379 * root.h: Added scm_source_whash among scm_sys_protects.
8381 * srcprop.c: New file: source properties.
8383 * srcprop.h: New file: source properties.
8385 * throw.c (jbsmob): Jump buffers are now correctly allocated.
8386 (Bug found by A. Green.)
8388 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8390 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8392 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8394 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8396 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8397 and should be called by the final client.
8399 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8401 * gc.h: Use the PROTO macro when declaring functions.
8402 * gc.c: Use the PROTO macro when declaring static functions.
8403 Remove the CPP hair around function definitions.
8405 * gc.c (scm_init_storage): Initialize scm_asyncs.
8407 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8408 preprocessor symbol; "__scm.h" is where it might get #defined.
8409 * __scm.h: Similar: #include <scmconfig.h> before testing
8412 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8414 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8416 * init.c (scm_boot_guile): Add init_func argument; call
8417 (*init_func) instead of calling scm_appinit; it's ucky to
8418 hard-code names for the user's procedures.
8419 * init.h (scm_boot_guile): Adjust declaration.
8421 * __scm.h (PROTO): New macro, for declaring functions with
8424 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8425 eliminate all the __STDC__ conditionals.
8426 (scm_boot_guile): Add declaration.
8427 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8428 Remove __STDC__ conditionals around function definitions; the
8429 declarations in init.h will provide the same information, more
8432 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8433 complain about it in the error message; the error message is
8434 adequate without that note, and there's nothing the user can do
8437 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8439 * Makefile.in (ancillary): Drop def.sed.
8441 * posix.c (scm_init_posix): Use numeric values, rather than
8442 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8443 F_OK. The symbols aren't available on some systems, and I'm
8444 pretty sure their values are fixed by common widespread practice.
8445 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8447 More functions unavailable on some systems.
8448 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8449 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8451 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8452 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8453 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8454 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8455 stub that signals an error as the #else.
8457 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8459 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8461 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8463 * unif.c: include ramap.h.
8465 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8467 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8469 * ports.c: include sys/ioctl.h.
8471 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8473 * configure.in: check for sys/ioctl.h.
8475 * ports.c: include <malloc.h> not "malloc.h".
8477 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8479 * fports.c: remove ttyname and tmpnam declarations.
8481 * posix.c: fewer ttyname declarations.
8483 * fports.c: include <string.h> not "string.h".
8485 * init.c, ioext.c: include string.h and unistd.h.
8487 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8489 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8490 genio.c, simpos.c, vports.c: include string.h.
8492 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8494 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8496 (scm_addr_buffer_size): change type from scm_sizet to int.
8497 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8498 from scm_sizet to int.
8500 * error.c: include unistd.h.
8502 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8505 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8507 * __scm.hd, def.sed: deleted.
8509 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8511 Changes for NeXT, suggested by Robert Brown.
8512 * configure.in: Call AC_TYPE_MODE_T.
8513 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8514 NeXT. Put header file list in alphabetical order.
8515 * configure, scmconfig.h.in: Regenerated.
8516 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8518 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8521 * acconfig.h: New file, providing documentation for the CPP
8522 symbols defined in configure.in
8523 * acconfig-1.5.h: Removed; superceded by the above.
8525 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8527 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8529 * fports.c (scm_open_file): don't return #f, throw error.
8531 * ioext.c (fileno): renamed from %fileno.
8532 (soft-fileno): deleted.
8534 * ports.c (scm_port_revealed): don't need to check for -1 from
8536 (scm_set_port_revealed_x): return unspecified, not #f.
8538 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8540 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8542 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8544 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8546 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8548 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8549 This is necessary on Ultrix, and doesn't hurt portability.
8551 * Makefile.in (dist-dir): New target, implementing a new dist system.
8552 (installed_h_files): Put in alphabetical order.
8553 Remove duplicate entries for markers.h and unif.h.
8554 (c_files): Remove duplicate entries for markers.c.
8555 (ancillary): Renamed from anillery; all uses changed. Remove
8556 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8557 Remove all the ../doc/* files; doc/Makefile.in handles that.
8559 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8561 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8562 every if must have an else, or else the whole command has a
8563 non-zero exit code whenever the if's condition is false.
8565 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8567 * posix.c: include string.h.
8569 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8571 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8574 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8575 Remove leading % from scheme names.
8576 Do not return error values, call SCM_SYSERROR or similar.
8578 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8580 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8582 * struct.c (scm_init_struct): new file.
8584 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8586 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8587 (scm_list_head): added list-head for rapidly chopping argument
8588 lists off of longer lists (and similar).
8590 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
8592 * objprop.c (scm_object_property): assq the cdr of the whash
8593 handle for obj, not the handle itself.
8595 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8597 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8598 weak hash tables last of all marking to avoid an obscure gc bug.
8599 WARNING: circular lists stored in a weak hash table will hose us.
8601 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8603 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8604 new functions similar to scm_substring_move_left_x and
8605 scm_substring_move_right_x.
8607 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8609 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8612 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8614 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8616 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8618 * strports.c (scm_strprint_obj): convenience function. C for
8619 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8621 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8622 removed to a separate library
8624 * init.c (scm_boot_guile): copied from guile-tcl.c.
8625 Initialization specific to tcl interpreters removed.
8627 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8629 * ports.c (scm_ports_prehistory): size malloced here doesn't
8630 matter so long as it is non-0 (got rid of "* 4").
8632 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8634 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8635 since its definition was bogus).
8637 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8639 * mallocs.[ch]: back again (for rx at least).
8641 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8643 * ports.c: removed functions relating to the mapping between ports
8644 and descriptors. (That stuff is unix-specific and should be collected
8645 in a separate library).
8647 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8648 (Tom Mckay@avanticorp.com)
8650 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8652 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8653 handled correctly (SCM_FREEP was applied to them) -- test for
8654 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
8655 being overwritten with #f. (brown@grettir.bibliotech.com)
8657 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
8659 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

8674 Generalized assoc and hash-table functions.
8675 Factored pairs.c into multiple files.
8677 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
8679 * gscm.c (gscm_run_scm): got rid of objprop.
8681 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
8683 * genio.c (scm_getc):
8684 NOTE: fgetc may not be interruptable.
8686 * procprop.c (scm_stand_in_scm_proc):
8687 NOTE: don't use a alist here.
8688 (scm_set_procedure_properties_x): fix type checking throughout this file.
8690 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
8692 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
8693 after freeing part of the port table.
8695 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
8697 * strports.c (scm_mkstrport):
8698 * vports.c (scm_make_soft_port): allocate a port table entry
8699 (possibly triggering gc) before setting the tag of the corresponding
8702 * pairs.c (scm_delq_x): never throw an error.
8704 * vectors.c (scm_make_vector): made the default vector fill argument
8705 into '() (much more useful than the previous value, "#unspecified")
8707 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
8709 * ports.c (scm_add_to_port_table): Added fields
8710 to port table entries: file_name, line_num, col.
8711 Update these in open_file, gen_getc and gen_ungetc.
8712 Added procedures to access those fields.
8714 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
8716 * procs.c (scm_make_subr_opt): new entry point for making
8719 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
8721 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
8723 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
8725 * numbers.c (scm_exact_p): This function no longer
8726 implements "integer?".
8728 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
8730 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
8731 (scm_gc_stats): return an assoc of useful data. Replaces "room"
8732 and the stats reporting formerlly built into repl.
8734 * repl.[ch]: removed.
8735 GC statistics keeping moved to gc.c.
8736 Other statistics keeping can be done from Scheme.
8737 REPLS are now written in Scheme.
8739 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
8741 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
8742 conservatively marked objects).
8744 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
8746 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
8748 * feature.c (scm_compiled_library_path): moved here from repl.c.
8749 This file is for stuff relating specifically to Scheme libraries
8752 * eval.c (scm_m_define): don't give warning about redefinition, don't
8755 NOTE: this should throw a resumable exception with parameters --
8756 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
8758 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
8760 * error.c: scm_warn eliminated.
8762 * read.c (scm_lreadr): extra right paren gets an error, not a warning.
8764 * repl.c, marksweep.c, gc.c (various):
8765 lose exit_report, growth_mon.
8767 * gscm.c: got rid of verbosity functions.
8769 Tue Feb 20 00:19:10 1996 Tom Lord <lord@beehive>
8771 * throw.c (scm_ithrow): guard against the bad-throw hook changing
8772 between the call to procedurep and use.
8774 * error.c (scm_everr):
8776 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
8779 * strports.c: don't reveal the port's string to the caller
8780 because it changes size.
8782 (stputc stwrite): check/change the strings length with interrupts
8785 * objprop.c (scm_set_object_property_x &c): use the generic
8786 hashing functions and be threadsafe.
8788 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
8789 (per suggestion jaffer@gnu.ai.mit.edu).
8791 * mbstrings.c (scm_multi_byte_string): guard against argument list
8794 * strings.c (scm_make_string): loop cleanup
8796 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer

8822 initialization to fix a race condition.
8824 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

8848 set the multi_byte flag correctly in symbols. This is wrong.
8849 intern_obbary_soft and msymbolize should take an extra parameter.
8850 Also, weird multibyte symbols don't print correctly.
8851 The weird symbol syntax is also a bit bogus (emacs doesn't quite
