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 * Makefile.am (CLEANFILES): Remove versiondat.h; that should only
19 be removed by `make distclean', since it's generated by configure.
20 * Makefile.in: Regenerated.
21 (Thanks to Robert Bihlmeyer.)
23 * strop.c (scm_substring_move_x): Signal an error if start1
24 doesn't come before end1. (Thanks to Karoly Lorentey).
26 * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
27 calling SCM_NIMP. (Thanks to Karoly Lorentey).
29 * version.c (scm_libguile_config_stamp): Deleted. See
30 corresponding change to ../ice-9/boot-9.scm.
31 * versiondat.h.in: Remove definition for GUILE_STAMP.
32 * version.h: Delete prototype.
33 * Makefile.in: Regenerated.
35 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
37 * filesys.c (scm_directory_p): new procedure "directory?" Returns
38 a boolean indicating whether its argument is a directory
39 port as returned by opendir (thanks to Dirk Herrmann for the
42 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
44 * backtrace.c (display_frame_expr): Don't print a newline.
45 (display_frame): Print the newline here instead.
46 (display_backtrace_body): Don't print "Backtrace:".
47 (scm_backtrace): Print "Backtrace:" here instead.
49 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
51 * procs.c (scm_setter): Signal WTA if handed an entity or operator
54 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
55 primitives. (Thanks to Greg Badros);
56 (scm_hook_to_list): New primitive; Hooks are now smobs.
58 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
60 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
61 of #f for the 10th vector element to avoid an exception
62 seen by Bernard Urban.
63 (scm_mktime): unneeded ASSERT removed.
65 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
67 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
70 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
72 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
74 * numbers.c: Converted comparison operations to dispatch on
75 generic if args don't match.
77 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
79 1999-09-06 James Blandy <jimb@mule.m17n.org>
81 * guile-snarf.c: Deleted. Snarfing should respect CPP
82 conditionals, so it needs to actually run CPP. Bleah.
84 1999-09-05 James Blandy <jimb@mule.m17n.org>
86 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
87 * guile-snarf.in: Be sure to exit with an error if CPP does.
88 * Makefile.am (.c.x): Delete the .x file and exit with an error
89 status if guile-snarf exits with an error status.
90 * Makefile.in: Regenerated.
92 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
93 scm_makekey, which doesn't exist any more. Guess nobody's using
96 * guile-snarf.c: New implementation of guile-snarf, meant to be
97 more robust than the shell script. I think it's complete, but I
98 haven't tested it at all, and I haven't changed the build process
99 to actually use it. We should compare its output against that of
100 the existing shell script, for all source files.
102 * guile-snarf.c (parse_args): Abort if we haven't handled some
105 1999-09-03 James Blandy <jimb@mule.m17n.org>
107 * load.c (scm_search_path): If the filename has any extension at
108 all, ignore the entire list of extensions. Also, don't check whether
109 the file is accessible. If the file exists, accessible or not, we
110 should return it. Inaccessible files should cause an error later.
111 (Thanks to Keisuke Nishida for the suggestions.)
113 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
115 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
116 atexit not available. (sunos4.1.4 needs it.)
118 1999-09-01 James Blandy <jimb@mule.m17n.org>
120 I take it all back --- bcopy does handle overlapping source and
121 destination areas correctly. At least on every system I could
122 find. But it is better to use AC_REPLACE_FUNCS than to introduce
123 new CPP conditionals.
124 * memmove.c: New file, implementing memmove in terms of bcopy.
125 * scmconfig.h.in: Regenerated.
127 Allocators should use the `void *' type for generic pointers.
128 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
129 argument and return types.
130 * gc.h: Corresponding changes to prototypes.
133 1999-08-31 James Blandy <jimb@mule.m17n.org>
135 * numbers.c (scm_init_numbers): Claim to support the `complex'
136 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
138 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
139 find (ice-9 boot-9) when Guile was compiled in a separate
140 directory from the source. (Thanks to Rodney Brown.)
141 * Makefile.in: Regenerated.
143 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
144 table lengths by the size of a single element when growing the
145 table. (Thanks to Bill Schottstaedt.)
147 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
149 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
150 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
151 since that cuts down the time for type dispatch by 50%.
153 1999-08-30 James Blandy <jimb@mule.m17n.org>
155 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
156 not a correct substitute for memmove, because it doesn't handle
157 overlapping source and destination areas on many platforms.
158 Overlaps are the primary reason to use memmove in the first place.
159 * ports.c (scm_ungetc): Same.
160 * strop.c (scm_substring_move_x): Same.
162 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
164 * gc.c (scm_init_storage): Skip registration of cleanup on systems
165 which lack atexit. (Is it important that cleanup is made
166 properly? Maybe we should replace all `exit' with `scm_exit' and
169 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
170 scm_struct_free_standard, scm_struct_free_entity): Declared to
171 return scm_sizet instead of size_t.
173 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
174 there on sunos4.1.4.)
176 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
178 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
179 Account for the case when second argument is unbound.
181 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
182 (Thanks to Karoly Lorentey.)
184 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
185 isn't present. (Thanks to Suzuki Toshiya.)
187 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
190 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
193 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
194 Bernard Urban and Ian Grant.)
196 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
197 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
198 change in the representation of entities and operators.)
200 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
202 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
203 don't allocate zero bytes (thanks to Bill Schottstaedt).
205 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
207 * procs.c (scm_setter): Converted to use generic dispatch.
209 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
212 * load.c (scm_search_path): Don't try extensions which already are
213 present at the end of the filename.
214 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
216 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
218 Cleanup and simplification of generic method dispatch.
219 Also, the quadruple representation of entity and operator
220 procedures has been replaced with single.
222 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
224 * print.c (scm_isymnames): Removed #@hash-dispatch.
226 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
227 from eval.c; Support 0 arity methods.
228 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
229 (scm_apply_generic_env): Removed.
230 Replaced slots proc0-3 with procedure.
232 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
233 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
234 SCM_OPERATOR_PROCEDURE.
235 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
236 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
238 * struct.c, struct.h: Replace 4 procedure slots with one.
239 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
241 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
244 * eval.c (scm_sym_args): Removed.
245 (SCM_CEVAL): Simplified entity application.
246 Moved dispatch code to objects.c.
248 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
250 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
252 * sort.c (closureless): Use scm_eval_body.
254 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
255 with a symbol as last form was first called normally and then via
256 `map' or some other mechanism using primitive apply, an ILOC was
259 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
261 This change extends the representation of primitive procedures
262 with more data fields, e.g. a place for documentation and true
263 procedure properties.
265 * procs.c, procs.h (scm_subr_entry): New type: Stores data
266 associated with subrs.
267 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
268 SCM_SUBR_DOC): New macros.
269 (scm_subr_table): New variable.
270 (scm_mark_subr_table): New function.
272 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
274 * gc.c (scm_gc_mark): Don't mark subr names here.
275 (scm_igc): Call scm_mark_subr_table.
278 This change implements a scheme for letting a generic work as a
279 shadow for a primitive procedure. If the primitive procedure
280 can't dispatch on its arguments, control is left over to the
281 generic. Normal wrong type arg errors will be generated until the
282 user has hung the first method on the primitive.
284 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
286 * procs.c, procs.h (scm_subr_p): New function (used internally).
288 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
290 * objects.c, objects.h (scm_primitive_generic): New class.
292 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
294 * print.c (scm_iprin1): Print primitive-generics.
296 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
297 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
299 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
300 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
301 primitives). NOTE: This means that it is now *required* to use
302 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
303 obscured representation that will be removed in the future anyway,
304 so backward compatibility is no problem here).
306 * numbers.c: Converted most numeric primitives (all but bit
307 comparison operations and bit operations) to dispatch on generic
311 Better support for applying generic functions.
313 * eval.c, eval.h (scm_eval_body): New function.
315 * objects.c (scm_call_generic_0, scm_call_generic_1,
316 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
320 Optimization of the generic function dispatch mechanism.
322 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
323 called scm_memoize_method instead of doing a second lookup.
325 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
330 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
331 scm_sysintern so that the binding connected with the subr name
332 isn't cleared when we give set = 0.
335 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
337 More transparent handling of ports with print states.
339 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
340 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
341 instead of a pair of a port and a print state. We'll need to cons
342 once extra in scm_printer_apply but the type system will be
343 cleaner, it will mix better with GOOPS, and, it will be even more
344 transparent to the user.
346 * print.c (scm_get_print_state): New procedure: Given an output
347 port, return the print state associated to it in the current print
348 chain, if one exists;
349 (scm_port_with_print_state): New procedure: Associate a
350 print-state with a port.
351 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
352 (scm_printer_apply): Wrap port and pstate as a smob;
353 (print_state_printer): Removed.
355 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
357 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
360 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
361 testing (otherwise the port-print-state trick won't be transparent
362 to the user; one example where this caused problems was in the
363 (ice-9 format) module).
365 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
367 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
368 SCM_UNSPECIFIED instead of the set value.
370 1999-08-20 James Blandy <jimb@mule.m17n.org>
372 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
374 * ports.h (enum scm_port_rw_active): New enum, containing
375 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
376 zero). The debugger knows about enums, but doesn't know about
378 (typedef scm_port): Declare rw_active member to be an enum
380 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
382 * ports.c (scm_add_to_port_table): Same.
383 * strports.c (st_flush, st_end_input): Same.
385 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
386 scm_must_realloc, and scm_done_malloc as appropriate.
388 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
390 * sort.c (quicksort): Added condition to protect the algorithm
391 from crashing the interpreter if the less predicate is buggy.
393 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
395 * fports.c (fport_write): fix line-buffering mode again.
396 (scm_open_file): recognise 'l' for line-buffering.
397 (scm_setvbuf): recognise _IOLBF for line-buffering.
399 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
401 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
404 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
407 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
409 * fports.c (fport_write): use memcpy instead of strncpy, in case
410 the data contains NUL.
412 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
414 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
416 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
417 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
418 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
419 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
420 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
421 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
422 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
423 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
424 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
425 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
426 scm_sym_ as prefix for symbols.
428 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
430 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
431 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
432 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
433 scm_sym_atcall_cc): Made global.
435 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
437 * eval.c (scm_sym_args): Made global.
439 * objects.c (scm_set_object_procedure_x): Disallow setting of
440 procedures for pure generic functions.
442 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
444 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
445 Scheme name from lseek to seek, but lseek was added recently so
446 it shouldn't be a big problem.
447 * ports.c, gdbint.c, ioext.c: changed callers.
449 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
451 * fports.c (fport_input_waiting): if select is used, return 1
452 instead of whatever FD_ISSET expands to. maybe it will be useful
453 to interpret the value from the input_waiting ptob procedure as a
454 lower bound on the number of bytes available.
456 * Mikael asked for a few names to be changed...
458 * ports.c (scm_make_port_type): take the write procedure as the
459 second argument instead of the flush procedure.
460 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
461 fflush -> flush, read_flush -> end_input, fclose -> close,
462 fill_buffer -> fill_input, ftruncate -> truncate,
463 input_waiting_p -> input_waiting.
465 * ports.c (end_input_void_port): was read_flush_void_port.
466 (scm_set_port_end_input): was scm_set_port_flush_input.
467 (scm_set_port_flush): was scm_set_port_write.
468 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
469 (scm_end_input): was scm_read_flush.
470 (scm_fill_input): was scm_fill_buffer.
471 (scm_flush): was scm_fflush.
472 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
473 (fport_end_input): was local_read_flush.
474 (fport_flush): was local_fflush.
475 (fport_close): was local_fclose.
476 (fport_truncate): was local_ftruncate.
477 (fport_seek): was local_seek.
478 (fport_free): was local_free.
479 (fport_fill_input): was fport_fill_buffer.
480 * strports.c (st_end_input): was st_read_flush.
481 (st_truncate): was st_ftruncate.
482 * vports.c: (sf_flush): was sfflush.
483 (sf_close): was sfclose.
484 (sf_fill_input): was sf_fill_buffer.
486 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
489 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
491 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
492 forms now contain the expressions to be dispatched upon instead of
493 depending on a surrounding lambda or let; Generic function
494 dispatch has been optimized; `apply' on a generic function now
495 works a little bit strangely. It uses a trick so that the type
496 dispatch code in SCM_CEVAL can be reused.
498 * objects.h, objects.c (scm_apply_generic_env): Added (used by
500 (scm_operator_p): Added.
501 (scm_sym_atdispatch): Added.
502 (scm_set_object_procedure_x): Modified to handle the new style
504 (scm_object_procedures): New debugging procedure.
506 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
508 * eval.c, eval.h (scm_sym_args): Added.
510 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
512 * feature.c, feature.h (scm_c_run_hook): Added.
514 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
515 cdrxnoap and loopnoap instead of begin and loop.
517 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
519 * ports.c (scm_putc, scm_puts),
520 * unif.c (scm_uniform_array_write): use scm_lfwrite.
521 * ports.c (scm_putc): change type of first argument from int to char.
523 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
525 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
526 SCM_IM_HASH_DISPATCH.
528 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
529 (scm_si_redfined, scm_si_hashsets): Moved.
531 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
532 flag which combines type and status info so that the class
533 redefinition protocol has zero cost during normal execution.
535 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
537 * ports.h (scm_ptob_descriptor): include a write procedure again.

541 * vports.c (scm_make_sfptob): set write proc in ptob.
542 * strports.c (scm_make_stptob): set write proc in ptob.
543 * ports.c (write_void_port): new procedure.

561 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
562 code, particularly an unnecessary test (len != size, where len ==
563 size). (Was this leftovers from debugging code, or have I missed
566 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
567 size. (Thanks to James Dean Palmer.)
569 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
570 (Thanks to Lorentey Karoly.)
572 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
574 * eval.c (scm_m_expand_body): Use scm_cons_source.
576 * struct.c (scm_print_struct): Use vtable name.
578 * print.c (scm_init_print): Set name of print state type.
580 * stacks.c (scm_init_stacks): Set name of stack type.
582 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
584 * eval.c (SCM_CEVAL): Removed old implementation of internal
587 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
589 * debug.c, debug.h (scm_reverse_lookup): Added.
590 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
591 internal procedure definitions; Don't use scm_i_inner_name.
593 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
596 * eval.h: Added prototypes for multi language support functions.
598 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
599 improper lists in the low-level representation, since that will
600 cause a begin to be prepended at macro expansion.
602 * eval.c (scm_cons_source): Version of cons which copies source
603 properties from an existing cell.
604 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
606 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
607 procedure source before calling scm_unmemocopy instead of faking
610 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
612 Ported `internal defines' fix from SCM. Original ChangeLog entry:
614 1998-07-09 Radey Shouman <radey@colorage.com>
616 * eval.c (ceval_1): Modifications to allow rewriting of interal
617 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
618 body of which it is the CAR is macro expanded by m_expand_body,
619 which rewrites internal DEFINE.
621 (m_expand_body): Added.
623 (m_macroexp1): Added argument to control error checking:
624 m_expand_body may speculatively expand forms in the wrong
625 environments. Made argument number checks conditional on
628 (m_body): Added, error checks bodies and inserts the ISYM tokens.
630 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
633 (m_cond): (m_case): (m_quote): Modified to avoid destructively
634 changing their argument forms. Since m_expand_body
635 speculatively macro expands forms the process must be
638 (m_ident_eqp): Fixed to use proper environment.
640 (renamed_ident): Added DEFER_INTS_EGC.
642 Added prototypes for static functions.
648 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
649 is false, do not produce an error for unbound variables, return a
650 pointer to cell_undef instead.
652 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
656 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
657 destructively changing their argument forms. Since m_expand_body
658 speculatively macro expands forms the process must be reversible.
660 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
661 SCM_IM_LET introduced by named lets.
663 (scm_m_letstar): Use scm_m_body instead of bodycheck.
665 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
666 scm_letrec. scm_letrec1 does not check for a null binding and
667 takes an additional argument to specify the ISYM of the body. Use
668 scm_m_body instead of bodycheck.
670 (scm_m_let): Use scm_m_body instead of bodycheck.
672 (scm_m_expand_body, scm_macroexp): New.
674 (unmemocopy): Account for ISYMs introduced by scm_m_body.
676 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
677 check=1. Throw error for internal defined that have not been
678 rewritten by scm_m_expand_body.
680 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
681 Removed prototype for SCM_APPLY.
683 * tags.h: Added extern declaration of scm_isymnames.
685 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
687 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
689 * lang.c: New file: Beginning of multi-language support.
691 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
693 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
694 (scm_dynamic_wind): Added argument checking for the after guard so
695 that we don't add garbage on the dynwind chain.
696 (scm_swap_bindings): Added.
698 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
699 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
700 (scm_isymnames): New isyms for multi-language support.
702 * eval.c (scm_nil, scm_t): New symbols.
703 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
704 forms for multi-language support.
706 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
708 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
710 Renamed functions in the random function library interface
711 from scm_i_XXX --> scm_c_XXX.
713 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
715 * ports.c (scm_putc): fix line-buffering.
717 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
719 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
720 scm_set_ptob_XXX --> scm_set_port_XXX.
722 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
724 * ports.c, ports.h (scm_make_port_type): New interface for
725 creation of port types (replaces scm_newptob). Just as for the
726 smobs, we need to separate the internal representation of smob
727 types from the interface, so that we easily can add new fields and
728 rearrange things without caring about backward compatibility.
729 This change was forced by the need in GOOPS to create classes
730 representing port types.
731 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
732 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
733 scm_set_ptob_seek, scm_set_ptob_truncate,
734 scm_set_ptob_input_waiting_p): New setters.
735 (scm_newptob): Rewritten to use scm_make_port_type. For backward

738 (scm_prinport): Removed.
739 (scm_port_print): Added.
740 (scm_print_port_mode): Added.
741 (void_port_ptob, print_void_port, close_void_port, noop0):
742 Removed. Removed #include "genio.h" Added #include "objects.h",
745 * fports.c (prinfport): Moved code from ports.c.
747 (scm_fptob): Removed. Instead use new interface.
748 (scm_make_fptob): Added. (Need to create basic ports in a
749 specific order in ports.c.)
751 * strports.c (scm_stptob, prinstpt, noop0): Removed
752 (scm_make_stptob): Added.
754 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
755 (scm_make_sfport): Added.
757 * filesys.c (scm_dir_print): Don't use the port printing code.
758 Instead provide specific directory printer.
760 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
762 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
765 * smob.c (scm_smob_print): Handle non-existing type name nicely.
766 Removed #include "genio.h"
768 * objects.c (scm_make_port_classes): New function ptr.
770 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
772 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
774 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
775 allow the 1st argument to be a fdes or filename as well as a
776 port (as in the filesys.c version).
778 * filesys.c (scm_truncate_file): removed.
780 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
782 * readline.c, readline.h: Removed.
784 * objects.c, objects.h (scm_port_class): Added.
785 (scm_class_of): Look up port class in scm_port_class.
786 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
787 SCM_INOUT_PCLASS_INDEX): Added.
790 * Makefile.am: Removed genio.c, genio.x.
794 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
796 * init.c: Make sure that scm_post_boot_init_modules is called only
797 once. (Important when using a dumped image.; Thanks to Bernard
800 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
802 * guardians.c (scm_guardian_zombify): Separate scanning for
803 zombies from marking the pairs of the free list.
805 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
806 use the macros. (Thanks to Michael Livshin.)
808 * eval.c (scm_m_lambda): Let bodycheck check the body of the
809 lambda. Let your sins be purified by the blood of the lambda.
810 (Thanks to Eric Hanchrow.)
812 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
813 (Thanks to Valdis Kletnieks.)
815 Fixes for EMX from Mikael Ståldal.
817 * filesys.c: #include <io.h>, if we have it.
818 * scmconfig.h.in: Regenerated.
820 * stime.c (ftime): Delete declaration for this function --- let
821 the system supply it.
823 Cleanups from John Bley.
825 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
827 * gsubr.c: Don't include "gsubr.h" twice.
829 Cleanups for compilation on Irix 6, from David Kaelbling.
831 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
832 regex_t pointer. This is what the callers have, mostly.
833 (scm_regexp_exec): Don't forget to pass the `rx' argument to
834 scm_regexp_error_msg.
836 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
837 int. That way, if we get a warning on this line, it's more likely
838 that we're really missing bits we care about.
840 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
843 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
844 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
845 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
846 cast at all is more appropriate in every case. At the moment, we
847 assume everywhere that SCM is an integral type anyway.
849 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
851 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
852 read_pos after scm_fill_buffer.
854 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
857 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
858 fports.c (fport_fill_buffer): implement the interface change.
860 * ports.c (scm_fill_buffer): interface change: no longer increments
861 read_pos past the character that's returned. it seems clearer to
862 leave it to the caller to decide what to do (thanks Jim).
864 * vports.c (sf_fill_buffer): put the read char into the buffer
865 as well as returning it.
867 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

881 * ports.c (scm_ftruncate): throw error if offset works out negative.
883 * strports.c (st_flush): increase string size in blocks of
884 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
885 it's greater and reset read_buf_size.
886 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
887 to be maintained for output ports too (it holds the written
888 part of the string, while write_buf may have unwritten buffer
890 (st_truncate): rewritten.
891 (top of file): added a few notes.
893 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
895 Patch from Greg Badros:
896 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
897 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
898 (function pointer) argument to scm_make_gsubr and scm_make_subr
899 calls. This avoids warnings in C++ programs using guile-snarf.
901 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
903 * strports.c (st_grow_port): set pt->read_pos. set
904 pt->read_buf_size one less than pt->write_buf_size if there's
905 an unwritten char at the end of the string. similarly for
907 (st_resize_port): renamed from st_grow_port.
908 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
909 seek from read_end instead of write_end for SEEK_END.
910 (st_ftruncate): calculate current length using readbuf, not write

922 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
924 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)

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

1021 * dynl-dl.c (sysdep_dynl_link): Added parenthesis around the
1022 trinary conditional in order for the flag computation to be
1025 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1027 * struct.c, struct.h:
1029 In order to support different kinds of deallocation, a destructor
1030 slot has been added to struct vtables. This allows for structs
1031 containing pointers to other memory blocks.
1033 (scm_struct_i_free): New hidden struct slot. Holds destructor for
1034 instances to this vtable.
1035 (scm_struct_free_0): New destructor: Doesn't deallocate data.

1100 pointers. (Thanks to Mark Elbrecht.)
1102 1999-06-19 Jim Blandy <jimb@savonarola.red-bean.com>
1104 Patch from Greg Harvey:
1105 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1106 around the condition of an `if', `while', etc., even if the
1107 condition is a macro invocation that expands to something
1108 surrounded by parens. It's more readable.
1110 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1111 proper lists, and of the appropriate lengths.
1112 (check_map_args): New function. (Thanks to Greg Harvey for the
1115 1999-06-19 Michael Livshin <mike@olan.com>
1117 * guardians.c (guardian_t): `next' - new field to be used for
1118 chaining the live guardians in a single-linked list during the GC
1120 (GUARDIAN_NEXT): convenience macro to access the `next' field.
1121 (guardians, guardians_size, n_guardians): deleted.

1133 * gc.c (scm_mallocated): Just make this signed.
1134 (scm_igc): Check for underflow by seeing if this is negative.
1136 * gc.h (scm_mallocated): Fix declaration.
1137 (Thanks to Greg Harvey.)
1139 * ports.h: #include <sys/types.h>, to get a definition for `off_t'.

1143 * stime.c (bdtime2c): Initialize lt->gmtoff and lt->tm_zone from
1144 sbd_time. (Thanks to Eric Hanchrow.)
1146 Fix from Ken Raeburn <raeburn@raeburn.org>:
1147 * weaks.c (scm_make_weak_vector): Add another extra slot before
1148 vector contents, to be used only during garbage collection.
1149 * weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
1150 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
1152 (scm_weak_size, scm_n_weak): Deleted.
1153 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
1154 vectors without allocating new storage during GC, using
1155 scm_weak_vectors as the head of the chain.
1156 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1157 instead of stepping through an array.
1158 (scm_gc_sweep): Update offset used to find start of weak vector to
1160 (scm_init_storage): Set scm_weak_vectors to EOL.
1162 Fix from Ken Raeburn <raeburn@raeburn.org>:
1163 * gc.c (already_in_gc): New variable.
1164 (scm_igc): Set and clear already_in_gc; abort if it's set at
1167 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
1169 Fix from Gary Houston:
1170 * fports.c (local_seek): Signal an error if the seek fails.
1171 * ports.c (scm_lseek): Don't check return value of port's seek
1172 function; it's its job to signal an error if there's a problem.
1174 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
1176 * strports.c (scm_call_with_output_string): Don't include the
1177 extra character at the end of the string in the result.
1179 * ioext.c (scm_read_line): Switch to reading properly.
1181 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
1182 scmsigs.c, strports.c, vports.c: Install the sources which
1183 actually correspond to the changes described below. I got the
1184 ChangeLog entries and the patch from two different places...
1186 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1188 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1189 it shows up as terrible performance, as we GC constantly.
1191 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1192 newline. A bit faster, and definitely hairier.
1193 (scm_read_line): Count newlines here instead.
1195 * strings.c (scm_take_str): New function.
1196 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1197 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
1198 scm_take_str, to avoid copying the string.
1200 Add some simple-minded support for line buffered ports.
1201 * ports.h (SCM_BUFLINE): New flag for ports.
1202 * init.c (scm_init_standard_ports): Request line-buffering on
1203 the standard output port.
1204 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1206 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1207 and there's a newline to be written, flush the port.
1209 Gary Houston's open-buffer port patches:
1211 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1213 * ports.c: (scm_lseek): clear buffers even if just reading current
1216 * fports.c (local_fclose): call local_fflush unconditionally.

1219 1999-04-25 Gary Houston <ghouston@easynet.co.uk>
1221 * ports.h (scm_port): make read_pos a pointer to const.
1222 strports.c: take care of rw_active and rw_randow.
1223 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
1224 strports.c (scm_mkstrport): check that pos is reasonable.
1225 ioext.c (scm_ftell, scm_fseek): use lseek.
1226 (SCM_CLEAR_BUFFERS): macro deleted.
1227 ioext.c (redirect_port: use ptob fflush, read_flush.

1229 ports.c (scm_newptob): set ftruncate.
1231 ports.c (scm_ftruncate): new procedure.
1232 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
1233 strports.c (st_seek, st_grow_port): new procs.
1234 fports.h (scm_port): change size types from int to off_t.
1235 ports.c (scm_init_ports): initialise the seek symbols here
1236 instead of in ioext.c.
1237 strports.c (scm_call_with_output_string): start with an empty
1238 string, so seek and ftruncate can be used.
1240 gdbint.c: adjust string port usage.
1242 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1244 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1245 equivalent to fflush for the read buffer.
1246 * ports.c (scm_newptob): set read_flush.
1247 ports.c (void_port_ptob): set read_flush.
1248 fports.c (local_read_flush): new proc. add to ptob.
1249 strport.c (st_read_flush): likewise.
1250 vport.c (sf_read_flush): likewise.
1251 fports.h (struct scm_fport): remove random member. there's nothing
1252 left but fdes. leaving it as a struct to allow for future changes.
1253 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1254 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1255 ptob proc if the read buffer is filled.
1257 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1259 * ports.h (scm_port): add a rw_random member and replace
1260 reading and writing members with rw_active member.
1261 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1263 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1265 * ports.h (struct scm_port_table): add writing and reading members
1266 to replace write_needs_seek: it isn't good enough for non-fports.
1267 ports.c, ioext.c, fports.c: corresponding changes.
1268 (struct scm_port_table): give it a typedef and rename to scm_port.
1269 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1270 corresponding changes.
1272 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
1274 * ports.c (scm_newptob): bugfix: set seek member.
1275 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
1276 and generalised to all port types.
1278 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
1280 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1281 signals (it was only being done for handlers installed from Scheme).
1282 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1283 waiting for input caused an EINTR error from read.
1285 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1287 * ports.h (struct scm_port_table): make all the char members
1288 unsigned, so they convert to int without becoming negative if large.
1290 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1292 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1293 with threads enabled. rename this procedure to
1294 fport_wait_for_input and take a port instead of a fdes.
1295 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1297 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1298 get readline support working again: use fdopen to get FILE objects.
1300 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1302 * gc.c (scm_init_storage): install an atexit proc to flush the
1304 (cleanup): the new proc. it sets a global variable which can be
1305 checked by the ptob flush procs to avoid trying to throw
1306 exceptions during exit. not very pleasant but it seems more reliable.
1307 * fports.c (local_fflush): check terminating variable and if set
1308 don't throw exception.
1309 * CHECKME: that the atexit proc is installed if unexec used.
1311 * throw.c (scm_handle_by_message): don't flush all ports here.
1312 it still causes bus errors.
1314 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1315 and move to ioext.c.
1317 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1319 * ports.c (scm_char_ready_p): check the port buffer and call the
1320 ptob entry if needed.
1322 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1323 ptob initialisers. use it in char-ready
1325 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1327 * vports.c (sfflush): modified to write a char (since softports
1328 currently use shortbuf.)
1330 * fports.c (scm_standard_stream_to_port): moved to init.c and
1333 * init.c (scm_init_standard_ports): make stdout and stderr
1334 unbuffered if connected to a terminal. with stdio they
1335 were line-buffered by default.
1337 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1340 * ports.h (scm_ptobfuns): change fflush return to void.
1341 change flush proc definitions.
1343 * strports.c (scm_call_with_output_string): get size from
1344 buffer instead of port stream.
1345 (st_flush): new proc.
1347 * ports.h (struct scm_port_table): added write_end member,
1348 as an optimisation. set it where write_buf_size is set.
1350 * ports.h (struct scm_port_table): change stream from void *
1351 back to SCM. SCM presumably must be large enough to hold a
1352 pointer (and probably vice versa but who knows.)
1353 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1355 (scm_puts): rewritten
1356 * fports.c (local_ffwrite, local_fputs): removed.
1357 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)
1358 * vports.c (sfputc, sfputs, sfwrite) likewise.
1359 * ports.c (write_void_port, puts_void_port): removed.
1360 (putc_void_port, getc_void_port, fgets_void_port): likewise.
1362 * ports.c (scm_lfwrite): rewritten using fport.c version.
1364 * fports.c (local_fputc): deleted.
1366 * ports.c (scm_add_to_port_table): initialise write_needs_seek.
1368 * ports.h (scm_ptobfuns): add seek function pointer.
1369 * fports.c: set it to local_seek, new procedure.
1372 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1373 use ptob for seek. take ptob instead of fport arg.
1375 * ports.h (struct scm_port_table): new member write_needs_seek,
1376 replaces reading member in fport struct.
1378 * vports.c (sfgetc): store the getted char into the buffer.
1379 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1380 the Scheme interface is still a procedure that gets a char.
1381 (scm_make_soft_port): set up the port buffer (shortbuf).
1383 * fports.c (local_fgetc, local_fgets): deleted.
1384 * strports.c (stgetc): likewise.
1385 * ports.c: scm_generic_fgets: likewise.
1387 * ports.h (scm_ptobfuns): add fill_buffer.
1388 * ports.c (scm_newptob): assign it.
1389 * strports.c (scm_mkstrport): set up the buffer.
1390 put just the string into the stream, not cons (pos stream).
1391 (stfill_buffer): new proc.
1393 * ports.h: fport buffer moved into port table: to be
1394 used for all port types.

1403 scm_getpeername, scm_recv, scm_send, scm_recvfrom,
1405 use SCM_FPORT_FDES. use SCM_OPFPORTP not SCM_FPORTP.
1407 * posix.c (scm_getgroups): use SCM_ALLOW/DEFER_INTS.

1465 ports.c fports.c ioext.c posix.c socket.c net_db.c filesys.c:
1466 removed all uses of SCM_DEFER/ALLOW ints for now. they were mainly
1467 just protecting errno. some may need to be put back.

1472 *fports.c (print_pipe_port, local_pclose, scm_pipob): deleted.

1587 1999-05-09 Jim Blandy <jimb@savonarola.red-bean.com>
1589 * strop.c (scm_string_capitalize_x): Use the SCM object `s' in

1593 * strop.c (scm_substring_move_x): New function, which can handle
1594 arbitrary overlapping substrings.

1624 * strop.h: fixed prototypes.
1626 * strop.c (scm_substring_move_left_x, scm_substring_move_right_x):

1671 * numbers.c (isfinite): Define this macro if not defined: Return a
1672 non-zero value if X is finite. (From ISO C 9x standard.)

1674 (Thanks to Jon Trowbridge and Greg Harvey.)
1676 1999-03-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1701 (scm_system_module_env_p): Assume root environment is no lookup
1704 * debug.c, eval.c, evalext.c, gdbint.c stacks.c:
1705 #include "modules.h".
1707 * modules.c, modules.h, eval.c, eval.h (scm_env_top_level,

1714 * error.c (scm_wta): Pass SCM_LIST1 (arg) instead of SCM_EOL to
1715 scm_misc_error when pos is a string. This allows for dispatching
1716 arbitrary error messages with one argument via SCM_ASSERT:

1725 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1727 Most of this batch of changes is about how to deal with extended
1728 types when an object system is loaded into Guile. A nice object
1729 system is capable of representing Guile's types as class objects.
1731 For example, we want a regular expression to be of class <regex>.
1732 But regular expressions are smobs which aren't under direct
1733 control of the object system, so there has to be some mechanism
1734 which informs the object system that a new class should be created
1735 which can represent the smob type. I call this a "wrapper class".
1737 * objects.c: #include "smob.h";
1738 (scm_class_keyword): Removed. (Class is automatically created by
1740 (scm_smob_class): Array of smob classes indexed by smobnum.
1741 (scm_make_extended_class): "Plugin" function pointer for creation
1742 of wrapper classes for smob and struct types.
1743 (scm_class_of): Handle compiled closures. (Currently regarded as
1745 Use scm_smob_class to handle smob types;
1746 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1747 through scm_smob_class;
1750 * smob.c (scm_newsmob): Also create a wrapper class if
1751 scm_smob_class has been initialized.
1753 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1754 type code and smobnum.
1756 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1757 (scm_struct_table): Weak key table with auxilliary information for
1758 struct types. Currently used for names and wrapper classes.
1759 (scm_struct_ihashq): Hash function for structs.
1760 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1761 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1762 for accessing names of vtables. The record implementation in
1763 boot-9.scm currently uses the setter to record the name of record
1764 types. When the object system is initialized, it can use this
1765 information to create wrapper classes with suitable names.
1766 (scm_init_struct): Allocate scm_struct_table.
1767 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1768 (struct tags are a finite resource and we might want to restrict
1769 the use of tags to vtables only. E.g., Goops only uses tags for
1771 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1773 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1776 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1777 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1778 Used for access of struct table entries.
1780 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1781 (scm_hash_fold): New procedure. Used to process all entries in a
1782 hash table (in no particular order).
1784 Argh! For the umpteenth time I got compilation errors because of
1785 the "intuitive" name `kw'. This has to have an end:
1787 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1788 "kw" --> "keywords" everywhere.
1789 (I doubt that this will cause big compatibility problems since the
1790 application interface is unaffected.)
1792 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1794 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1796 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1797 column inums to native form.
1799 Improvement of backtraces: Introduces a new stack narrowing
1800 specifier, #t, for the inner cut. (See further in the comments in
1801 stacks.c:narrow_stack ().)
1803 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
1804 (Used to flag certain system procedures which shouldn't turn up in
1807 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1808 modules which aren't "user" modules and the code of which
1809 shouldn't turn up in backtraces.)

1812 Extract the lookup closure from an environment.
1813 (scm_system_module_env_p): New function: Return non-#f if MODULE
1816 * stacks.c: #include "eval.h"; #include "procprop.h";
1817 (narrow_stack): Handle new narrowing specifier #t.
1819 * debug.c (scm_procedure_name): Use name property in the default
1822 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1824 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1826 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1827 procedure throughout.
1829 * print.c (scm_iprin1): Removed extraneous space when printing
1830 procedure-with-setters.
1832 Entity and operator setter slots were introduced as a complement
1833 to the <procedure-with-setter> type in order to support entities
1834 and operators with setters in a reasonable and efficient way.
1835 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1838 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1850 * objects.h (SCM_OBJ_CLASS_REDEF): New macro: Find class slots
1851 directly through the instance.
1853 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1855 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1856 scm_struct_i_flags instead of scm_vtable_index_layout!
1858 * list.c (scm_list_star): New procedure.
1860 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1941 SYMB now point to const.
1943 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1945 * print.c (scm_iprin1): Use scm_procedure_name instead of
1946 scm_procedure_property for compiled closures.
1948 * tags.h (scm_tc7_pws): New procedure type. Four representations
1949 for procedure-with-setters were considered before selecting this
1952 1. A closure where the CODE and ENV slots are used to represent
1953 the getter and a new SETTER slot is used for the setter. The
1954 original getter is stored as a `getter' procedure property. For
1955 closure getters, the CODE and ENV slots contains a copy of the
1956 getter's CODE and ENV slots. For subr getters, the CODE contains
1959 2. A compiled closure with a call to the getter in the cclo
1960 procedure. The getter and setter are stored in slots 1 and 2.
1962 3. An entity (i.e. a struct with an associated procedure) with a
1963 call to the getter in the entity procedure and the setter stored
1964 in slot 0. The original getter is stored in slot 1.
1966 4. A new primitive procedure type supported in the evaluator. The
1967 getter and setter are stored in a GETTER and SETTER slot. A call
1968 to this procedure type results in a retrieval of the getter and a
1969 jump back to the correct eval dispatcher.
1971 Representation 4 was selected because of efficiency and
1974 Rep 1 has the advantage that there is zero penalty for closure
1975 getters, but primitive getters will get considerable overhead
1976 because the procedure-with-getter will be a closure which calls
1979 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1980 <procedure-with-setter>, but together with rep 2 it suffers from a
1981 three level dispatch for non-GOOPS getters:
1983 cclo/struct --> dispatch proc --> getter
1985 This is because the dispatch procedure must take an extra initial
1986 argument (cclo for rep 2, struct for rep 3).
1988 Rep 4 has the single disadvantage that it uses up one tc7 type
1989 code, but the plan for uniform vectors will very likely free tc7
1990 codes, so this is probably no big problem. Also note that the
1991 GETTER and SETTER slots can live directly on the heap, using the
1992 new four-word cells.
1994 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

2074 * random.c: Removed alloca includes.
2076 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2078 * Makefile.in: This changed, for some reason I don't really
2079 understand, when I ran automake in the top level directory. This
2080 may be contamination by Cygnus internal releases. If you re-run
2081 automake and this change gets reverted, don't worry about it.
2083 1999-01-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2085 * sort.c, sort.h: New files: Implement slib's and scsh's sort

2099 Interface same as slib's.
2101 * Makefile.am: Added random.c, random.h, random.x.
2103 * init.c: #include "random.h";

2106 1998-12-23 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2108 * Makefile.am: New files: guardians.c, guardians.x, guardians.h
2110 * guardians.c, guardians.h (scm_make_guardian,
2111 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
2112 scm_get_one_zombie, scm_init_guardian): This is an implementation
2113 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
2114 David Eby (1993) "Guardians in a Generation-Based Garbage
2115 Collector" ACM SIGPLAN Conference on Programming Language Design
2116 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
2117 /pub/scheme-repository/doc/pubs/guardians.ps.gz
2118 Author: Michael N. Livshin.
2120 * gc.h (SCM_MARKEDP, SCM_NMARKEDP): New macros.
2122 * gc.c (scm_igc): Call scm_guardian_gc_init and
2123 scm_guardian_zombify.
2125 * init.c (scm_boot_guile_1): Call scm_init_guardian.
2127 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2129 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
2132 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2134 Move the procedure slots of entities to invisible slots (so that
2135 we can have operator class objects which themselves are entities).
2136 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
2137 SCM_STRUCTF_ENTITY): New constants.
2139 * struct.c (scm_make_struct): Allocate "invisible" room for
2140 procedures if SCM_STRUCTF_ENTITY is set in vtable.
2142 * gc.c (scm_gc_mark): Mark entity procedures.
2144 * struct.c, struct.h (scm_alloc_struct): Renamed from alloc_struct

2149 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
2150 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
2152 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
2154 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
2155 of syntactic forms, similar to SCM_PROC.
2156 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
2157 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
2158 for the name symbols when needed.
2160 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
2162 * Makefile.in: Regenerated.
2164 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
2166 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
2167 take the address of _into; it might be a register. Just have
2168 scm_debug_newcell return the new cell.
2169 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2170 taking the address of a place to store it as an argument.
2171 * gc.h (scm_debug_newcell): Change declaration.
2172 (Thanks to Greg Harvey.)
2174 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2176 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
2177 Replaces old names serial-array-copy! and serial-array-map!.
2179 * evalext.c (map-in-order): New name. Replaces serial-map.
2181 1998-12-05 Jim Blandy <jimb@totoro.red-bean.com>
2183 * smob.c (freeprint): New function.
2184 (freecell): Use it to print freed objects, for slightly easier
2187 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2189 * backtrace.c (display_frame): Made more robust. Doesn't throw an
2190 error if no source properties can be found for a frame. (Thanks
2191 to Christian Lynbech.)
2193 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2195 * objects.h: Removed slots direct_supers and direct_slots from the
2196 definitions of the rudimentary classes described by objects.h.
2198 * objects.c, objects.h (scm_entity_p): New procedure. Together
2199 with the predicates scm_procedure_p and scm_struct_p, this
2200 predicate makes it possible to differ between structs, entities
2203 * modules.c, modules.h (scm_resolve_module): New function.
2205 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2207 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2208 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2211 * objects.c (scm_entity_p): New procedure.
2213 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
2214 for asubrs, rpsubrs, lsubrs and lsubr_2s.
2216 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2218 * procprop.h (scm_i_procedure_arity): Added declaration.
2220 * procprop.c (scm_i_procedure_arity): Made global; New code to
2221 handle operators and entities.
2222 (scm_procedure_property): No need to call scm_procedure_p since
2223 scm_i_procedure_arity now does all necessary type checking.
2224 Added #include "objects.h".
2226 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2227 s_add_hook_x --> s_remove_hook_x.
2228 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
2229 Added #include "procprop.h"
2231 * feature.c, feature.h (scm_reset_hook_x): New procedure.
2232 (scm_make_hook): Optional argument defines number of arguments to
2234 (scm_make_named_hook): Take number of args as second arg.
2235 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2236 boot-9.scm for a while); First arg is the hook. The rest are
2237 arguments passed on to the hook procedures.
2239 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2241 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2242 scm_logbit_p): Do the computation in ulongs. This is not as nice
2243 as doing it in bignums, but at least it's good enough for
2244 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2246 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2247 subexpressions. (Thanks to Charbel Jacquin.)
2249 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2251 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2252 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2253 (scm_make_named_hook): New function.
2255 * feature.c: Added #include "eval.h".
2257 * modules.c (scm_make_module): Beautify the module.
2259 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2261 * modules.c, modules.h: New files: C interface to modules. (This
2262 is necessary in order to interface the object system to Guile
2263 properly. The guts of these modules will be replaced by the new
2264 module system in the future.)
2266 * init.c: Added #include "modules.h"
2267 (scm_boot_guile_1): Call scm_init_modules.
2268 (invoke_main_func): Call scm_post_boot_init_modules.
2270 * Makefile.am: Added modules.c, modules.x, modules.h.
2272 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2274 * procs.c: #include "objects.h"
2275 (scm_procedure_p): Return #t also on structs which are operators.
2277 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2278 <operator-metaclass> and <entity-class> to <standard-class>,
2279 <operator-class> and <entity> in order to conform with STKlos
2282 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2283 which isn't an operator.
2284 (SCM_APPLY): Ditto, but jump to badproc.
2286 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2288 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2289 Previously, structs implanted in code were interpreted as forms
2290 the operator of which was a gloc. We solve this by checking for
2291 the zero in the emulated vcell in the struct vtable. Since
2292 implanted structs always will look like forms with a gloc
2293 operator, execution will only be slowed down by maximally one
2294 extra test-and-branch per application.
2296 * evalext.c (scm_definedp): Removed check for isyms; Added a
2297 second optional argument: It is now possible to supply an
2298 evaluation environment in which to look for the symbol.
2300 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2302 * readline.c (scm_init_readline): Set
2303 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2305 * coop.c (coop_condition_variable_wait): Removed
2306 (coop_condition_variable_wait_mutex): Folded logic of
2307 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2308 prevent condvar signal lossage. Previously, another thread could
2309 start to run after unlocking the mutex but before putting the
2310 current thread on the wait queue. If that thread then would
2311 signal the first, the signal would be lost. (Thanks to Christian
2314 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2316 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2319 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2321 * objects.c (scm_i_make_class_object): Renamed from
2322 make_class_object; exported; error checking moved to
2323 scm_make_class_object and scm_make_subclass_object.
2324 (scm_make_class_object, scm_make_subclass_object): Use
2325 scm_i_make_class_object.
2326 (scm_make_subclass_object): Let the subclass have same metaclass
2329 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2331 * debug.c (scm_debug_options): Bugfix: Set the value of
2332 scm_stack_checking_enabled_p after setting debug options;
2333 #include "stackchk.h". (Thanks to Richard Polton.)
2335 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2337 * unif.c (scm_array_contents): removed unnecessary test for 0
2340 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2342 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2343 Replaced by macro `collect' in boot-9.scm.
2345 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2347 * eval.c (scm_copy_tree): Copy source properties if existent.
2349 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2350 don't, we may end up passing memoized source to a transformer.)
2352 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2354 * stack.c (get_applybody): Help function which lookups the first
2355 body form of the apply closure.
2356 (read_frames): Prevent the source of the first form of the apply
2357 closure from being recorded. This would only be confusing.
2359 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2360 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2362 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2364 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2366 (read_frames): Use SCM_MACROEXPP.
2368 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2370 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2371 don't contain interesting information since all arguments are
2372 present in the frame which applies the compiled closure anyway.);
2373 Skip the transformer application frames.
2375 * print.c (scm_iprin1): Print gsubrs as primitives.
2377 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2379 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2381 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2382 that we can identify these in a backtrace. (This change doesn't
2383 introduce any significant speed penalty.)
2385 * eval.c: Added note about `serial-map' using scm_map.
2387 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2388 readline options. They should reside in their own options array.
2390 * readline.c, readline.h (scm_readline_options,
2391 scm_readline_opts): Moved readline options here.
2393 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2395 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2396 SCM_ROCHARS instead of SCM_CHARS.
2398 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2399 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2401 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2403 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2404 This is quite important since the latter clears the
2405 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2406 every single character read...
2408 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2410 * print.c (scm_iprin1): Removed suspect looking (and indeed
2411 malevolent) semicolon after test for user supplied closure print
2412 procedure. (Thanks to Telford Tendys.)
2414 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2415 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2416 starting to search the list. Removed call to sloppy_mem_check.
2418 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2419 procedures: Same as scm_delq_x et al, but delete maximally one
2422 * options.c (scm_options, scm_init_options): GC-protect option
2423 values of type SCM. (Thanks to Telford Tendys.)
2425 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2427 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2428 make sure that there always is a "real" scm_lookupcar.
2430 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2432 * read.c, read.h (scm_read_opts): New read options
2433 "history-length" and "history-file".
2434 (scm_read_options): Stifle history to history length.
2436 * readline.c (scm_read_history, scm_write_history): New procedures.
2438 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2440 * eval.h (scm_macro_eval_x): Removed declaration.
2442 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2443 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2444 Renamed and made global.
2446 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2447 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2449 * evalext.c, evalext.h: New files. Contain non-R5RS things
2450 having to do with evaluation.
2452 * evalext.c (scm_serial_map): New procedure: Version of `map'
2453 which guarantees that the procedure is applied to the lists in
2455 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2456 returns a list of the results of the body forms instead of the
2457 result of the last body form.
2458 (scm_definedp, scm_m_undefine): Moved from eval.c
2460 * evalext.h (scm_m_sequence_to_list): Added declaration.
2462 * macros.c, macros.h: New files.
2463 (scm_procedure_to_syntax, scm_procedure_to_macro,
2464 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2465 scm_macro_name, scm_macro_transformer): Moved from eval.c
2466 (scm_make_synt): Moved from eval.c
2468 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2470 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2473 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2475 * debug.c, print.c: Added #include "macros.h".
2477 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2479 This change adds the ability to use `unread-char' multiple times
2480 without interspersed reads and adds the new procedure
2481 `unread-string'. The change is optimized for the common case of
2482 unreading a single character. This is also the reason behind the
2483 choice to store characters in the port itself: in most cases no
2484 extra malloc is required.
2486 The amount of code in some macros in ports.h has been increased to
2487 the extent that they would fit better as C functions, but, since
2488 this code belongs to the port representation, such functions
2489 should be placed in ports.c which would cause calls back and forth
2490 between ports.c and genio.c. That is not good for performance.
2491 Also, keeping them as macros allows the compiler to do some
2492 optimizations which are needed to make the current interface
2493 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2495 One benchmark (Guile startup time) indicates an increase of
2496 loading speed of 1%. Another (reading (using `read') boot-9.scm
2497 10 times) shows no change in performance.
2499 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2500 made to find a beautiful solution.)
2502 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2503 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2504 character. (SCM_CLRDY clears all.)
2505 (SCM_N_READY_CHARS): New macro: Returns number of unread
2506 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2507 (struct scm_port_table): New fields: `entry' contains port table
2508 index, `cp' points to last unread char, `cbuf' is the buffer for
2509 unread chars, `cbufend' points after end of the character buffer.
2511 * ports.h, ports.c (scm_unread_string): New procedure.
2512 (scm_grow_port_cbuf): New function.
2514 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2516 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2517 to read unread characters. Use SCM_TRY_CLRDY instead of
2520 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2522 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2524 * genio.c, genio.h (scm_ungets): New function.
2526 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2529 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2531 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2532 declarations. (Thanks to Russ McManus.)
2534 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2536 * numbers.c (num2long): As a software archeologist, I'm proud of
2537 this finding! :) Preliminary dating suggests an almost 4 year old
2538 remnant from the SCM ancestor. The sample has been removed from
2539 the finding site and is now safely stored in the repository.
2541 * numbers.h: Removed prototype for num2long.
2543 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2545 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2546 array as second arg.
2547 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2548 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2549 * gh.h: Updated and added prototypes.
2551 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2553 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2555 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2557 * guile-snarf.in: Never generate an empty file. (Thanks to
2560 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2561 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2562 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2563 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2564 gh_new_procedure5_0): Specify argument types, to appease C++
2565 compilers. (Thanks to Brad Bowman.)
2567 Bug reports from Russ McManus:
2568 * guile-snarf.in: If the CPP environment variable is set, use that
2569 as the C preprocessor, instead of the preprocessor autoconf
2571 * snarf.h (SCM_PROC): Cast the function pointer passed to
2572 scm_make_gsubr, to satisfy C++.
2574 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2575 Use the handler passed, instead of ignoring it and using
2576 gh_standard_handler. (Thanks to Etienne Bernard.)

2580 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

2603 * script.c (scm_compile_shell_switches): Define
2604 use-emacs-interface in the root module, so the repl code can see
2605 it. See today's change to top-repl in ice-9/boot-9.scm.
2607 * filesys.c (set_element, get_element): Make sure that `element'
2608 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2609 Boekemeier and Jorgen "forcer" Schaefer.)
2611 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2613 * chars.c (scm_charnames): In ASCII character name table, make
2614 newlines print as #\newline by default, not #\nl.
2616 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2617 alphabetical order. Oh thrills. But it helps me know how far
2618 along in the compilation I am.
2619 * Makefile.in: Regenerated.
2621 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2623 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2624 #bytes(...) to #y(...), and syntax for short vectors from
2625 #short(...) to #h(...). This may seem nutty, but, like the other
2626 uniform vectors, byte vectors and short vectors want to have the
2627 same print and read syntax (and, more basic, want to have read
2628 syntax!). Changing the read syntax to use multiple characters
2629 after the hash sign breaks with the conventions used in R5RS and
2630 the conventions used for the other uniform vectors. It also
2631 introduces complexity in the current reader, both on the C and
2632 Scheme levels. (The Right solution is probably to change the
2633 syntax and prototypes for uniform vectors entirely.)
2635 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2637 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2638 (Thanks to Jorgen "forcer" Schaefer.)
2639 * ports.h (SCM_NOFTELL): New flag.
2640 * fports.c (local_fgets): If it's set, use the generic fgets.
2641 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2643 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2645 * script.c (scm_compile_shell_switches): Add handling of -q switch
2646 (inhibit loading of user init file).
2647 (scm_shell_usage): Add usage text for -q switch.
2648 (scm_compile_shell_switches): Always load user init file first if
2649 it is loaded at all.
2651 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2653 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2654 and is now broken under NetBSD. I can't fathom what it's trying
2655 to do, so I've replaced it with something that I do understand,
2656 which seems to work, and which isn't broken on NetBSD. "Progress?
2657 You Decide." (Thanks to Perry Metzger.)
2659 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2660 signed/unsigned comparison.
2662 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2664 Warning fixes from Greg Harvey:
2665 * unif.c (scm_array_set_x): initializer for pos
2666 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2667 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2668 initializers for field_type, since EGCS so desparately wants to
2670 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2671 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2672 when GUILE_DEBUG is defined.
2673 * dynwind.h (scm_wind_chain): Same.
2674 * ports.h (scm_pt_size, scm_pt_member): Same.
2675 * print.h (scm_current_pstate): Same.
2676 * procs.h (scm_make_cclo): Same.
2678 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2680 Handle short and long long uniform arrays properly. (Thanks to
2682 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2683 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2684 scm_tc7_llvect (long long vectors).
2686 Change the way libguile and boot-9.scm are timestamped, to try to
2687 get rid of these spurious mismatch warnings. Now both
2688 libguile/versiondat.h and ice-9/version.scm are generated directly
2689 by the configuration process, rather than having version.scm
2690 generated directly, and libguile/versiondat.h generated by the
2691 Makefile, which is generated by configure. It seems that
2692 sometimes the Makefile would change, but versiondat.h depends on
2693 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2694 * Makefile.am (versiondat.h): Target removed; this is generated
2695 directly by the configure script now.
2696 (BUILT_SOURCES): Remove versiondat.h.
2697 * versiondat.h.in: New file, transformed by the configure script
2699 * Makefile.in: Regenerated.
2701 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2702 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2703 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2704 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2705 if we want to use them in a header file some day, we can. (Thanks
2706 to Michael Livshin.)
2708 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2709 SCM numbers, so we won't have rollover problems; the range of a
2710 signed long in milliseconds is about 25 days. (Thanks to Karl
2713 Don't redefine sleep and usleep; fix this problem now.
2714 * coop.c (sleep, usleep): Remove declarations; we don't use or
2715 redefine these any more.
2716 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2717 job of usleep and sleep in a thread-friendly way. We can use
2718 these in the rest of Guile. Define versions for systems both with
2719 and without iselect.
2720 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2721 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2722 we're just using it, not redefining it, we can use a K&R style
2724 (sleep): Declare this, too, if the system hasn't.
2725 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2726 scm_uthread_sleep if they're available; otherwise, just call the
2728 * scmconfig.h.in: Regenerated.
2730 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2732 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2734 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2736 * threads.c: Doc fix.
2738 The argument type of usleep varies from system to system,
2739 as does the return type. We really shouldn't be redefining usleep
2740 at all, but I don't have time to clean that up before the 1.3.
2741 release. It's on the schedule for afterwards. (Thanks to Julian
2743 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2745 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2746 * scmconfig.h: Regenerated.
2748 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2749 right way to handle system variation. Autoconf's approach is the
2751 * simpos.h (scm_software_type): Declaration deleted.
2753 * script.c (scm_find_executable): Don't test if unix is #defined
2754 here; first, NetBSD doesn't #define it, and second, it's the wrong
2755 way to go about these things. (Thanks to Perry Metzger.)
2756 (dld_find_executable): Delete this MSDOS support code. This isn't
2757 the way we want to support this; it needs to be rethunk at a
2760 * genio.c (scm_do_read_line): Don't just politely check that the
2761 line was either non-empty or EOF. Abort if it's empty and not
2764 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2766 * scmconfig.h.in: Regenerated.
2768 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2771 * genio.c (scm_do_read_line): Count lines correctly when the file
2772 doesn't end in a newline.
2774 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2776 * genio.c (scm_do_read_line): Maintain the line count correctly.
2777 (Thanks to Harvey J. Stein and Greg Harvey.)
2779 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2782 * numbers.c (big2str): Protect t from garbage collection until
2783 we're done. (Thanks to Gary Houston.)
2785 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2787 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2789 * Makefile.in: Regenerated.
2791 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2792 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2795 Do magic to mix reads and writes on stdio FILE-based ports.
2796 (Thanks to Christian Lynbech.)
2797 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2799 (pre_read, pre_write): New functions.
2800 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2801 local_fputs): Call them.
2802 (local_fflush): Mark the port as ready for reading and writing.
2803 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2804 flags on new port objects. This might not be accurate --- who
2805 knows what state the FILE * is in when we get it --- but it won't
2806 do extraneous calls to fflush or fseek, so it's no worse than the
2807 behavior before this change.
2808 * ports.h: Add comment.
2810 Centralize the creation of port objects based on stdio FILE * in
2811 fports.c; don't just throw them together anywhere.
2812 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2813 what the rest of Guile wants. Don't set the revealed count;
2814 that's only appropriate for stdin, stdout, stderr.
2815 (scm_standard_stream_to_port): This function does set the revealed
2817 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2818 not scm_stdio_to_port.
2819 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2820 * fports.c (scm_open_file): Same.
2821 * posix.c (scm_pipe): Same.
2822 * socket.c (scm_sock_fd_to_port): Same.
2823 * ioext.c (scm_fdopen): Same.
2824 (scm_freopen): Moved from here to...
2825 * fports.c (scm_freopen): ... here. This is really something that
2826 munges the internals of an fport, so it should go here.
2827 * fports.h (scm_stdio_to_port): Adjust prototype.
2828 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2829 * ioext.h (scm_freopen): Prototype removed.
2831 * filesys.c (set_element, get_element): This can work on both pipe
2832 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2835 * scmconfig.h.in: Regenerated.
2837 Change the definition of the functions in scm_ptobfuns so that
2838 they get passed the port object, not the port's stream.
2839 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2840 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2841 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2842 Pass the port itself to the scm_ptobs function.
2843 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2844 scm_generic_fgets): Same.
2845 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2846 getc_void_port, fgets_void_port, close_void_port): Just change the
2847 argument names; these functions don't really do anything.
2848 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2849 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2850 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2851 Also, use prototyped definitions, and get rid of the extra
2853 (scm_fptob, scm_pipob): We don't need casts here any more.
2854 * strports.c (prinstpt): Use prototype declarations.
2855 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2856 and use SCM_STREAM to get the string info. Also, use prototyped
2857 definitions, and get rid of the extra declarations.
2858 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2861 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2862 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2864 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2865 scm_fgets, for consistency.
2866 (scm_fptop, scm_pipob): References updated.
2868 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2870 Include the source location in error messages for scripts.
2871 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2872 stack is still there when we catch the error.
2873 * throw.c (handler_message): If we are handling an error with a
2874 message, then put together the proper arguments and call
2875 scm_display_error, instead of scm_display_error_message. That
2876 displays source location, if it can find it.
2878 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2880 * gc.c (scm_unprotect_object): Change this so that calls to
2881 scm_protect_object and scm_unprotect_object nest properly.
2882 (scm_protect_object): Doc fixes.
2884 * strings.c (scm_string_set_x): Require the argument to be a
2885 writable string, not a substring or a symbol.
2886 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2887 (Thanks to John Redford and Charbel Jacquin.)
2889 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2891 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2893 * eval.c (safe_setjmp): Remove this misunderstanding.
2894 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2897 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2899 * libguile.h: Mark these as C declarations, for compilation by C++
2902 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2903 __cplusplus clause. I seriously doubt this ever worked the way
2904 the author seems to have intended.
2906 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2908 Utterly needless cleanups to hopelessly messy code.
2909 * ports.c: Doc fixes.
2910 (scm_fflush): Moved to ...
2911 * genio.c (scm_fflush): ... here, amongst all the other port
2912 method invocation functions.
2913 * genio.h, ports.h: The prototype moves too.
2915 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2917 * backtrace.c (display_error_body): The current frame does not
2918 always have a parent frame; consider a function called directly
2919 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2922 * alloca.c (alloca): Undo yesterday's changes, and simply call
2923 malloc directly for storage, and abort if we don't get what we
2924 want. The situation is much simpler --- just call malloc. Emacs
2925 has bizarre/evil requirements (signal handlers might malloc unless
2926 you set this global flag, so you have to set the flag around all
2927 calls to malloc) which we are certainly not going to conform to,
2928 so we can do the simple and obvious thing.
2930 * coop.c (coop_condition_variable_wait): Make this function
2931 static. It's only useful internally --- you should never just
2932 wait on a condition variable.
2933 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2935 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2937 * unif.c (scm_array_set_x): Accept any kind of number as an
2938 element for a uniform vector of doubles. This is more consistent
2939 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2941 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2942 works; I can't conveniently test it myself. (Thanks to Dvid
2943 Tillman for the bug report.)
2945 * init.c: Doc fixes.
2947 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2948 from here, not from scm_compile_shell_switches (which is a pretty
2949 dumb place to do it).
2950 (scm_load_startup_files): New function.
2951 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2952 * script.c (scm_compile_shell_switches): Don't load the startup
2954 (scm_ice_9_already_loaded): Variable moved.
2955 * init.c (scm_load_startup_files): Prototype for new function.
2956 * gh_init.c (gh_enter): Doc fix.
2958 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2960 Some anti-warning changes from Greg Harvey.
2961 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2962 warnings when it doesn't understand our NORETURN declarations in
2964 * posix.c (scm_mknod): Similar.
2966 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2968 * posix.c (scm_getpwuid): If we can't find an entry, return our
2969 own message, instead of using scm_syserror --- the getpwMUMBLE
2970 functions don't set `errno' to anything interesting.
2972 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2974 Get rid of warnings from the cooperative threading system.
2975 * threads.h (scm_single_thread_p, scm_yield,
2976 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2977 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2978 scm_wait_condition_variable, scm_signal_condition_variable): Add
2979 prototypes for these Scheme-visible functions.
2980 * coop-defs.h (coop_next_runnable_thread,
2981 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2982 Prototypes for these here, even though they're from iselect.c.
2983 (coop_condition_variable_wait, coop_join): Add prototypes.
2984 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2985 scm_threads_free_condvar): Make these smob functions static.
2986 * coop-threads.h (coop_init): Give this a real prototype.
2987 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2988 (coop_next_runnable_thread): No need to provide prototype; it's in
2991 * scmconfig.h.in: .detarenegeR
2993 * iselect.c, threads.c: Doc fixes.
2995 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2997 * Makefile.in: Regenerated with a patched automake, to get
2998 dependency generation right when using EGCS.
3000 * inet_aton.c (inet_aton): Add prototype, to remove compiler
3001 warning. (Thanks to Robert Pluim.)
3003 * inet_aton.c (inet_aton): Reassure the compiler that the
3004 arguments to the <ctype.h> macros are all unsigned characters, not
3007 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3009 Getting rid of more warnings...
3010 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
3011 today's change to ../configure.in.
3012 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
3013 * scmconfig.h.in: Regenertaded.de.,.__
3014 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
3015 (scm_localtime, scm_mktime): Use a const char * to manipulate the
3018 * readline.c: Doc fix.
3019 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
3020 * readline.h (scm_filename_completion_function): Add prototype.
3021 (scm_init_readline): Make this into a prototype.
3023 * readline.c (scm_filename_completion_function): Use SCM_PROC to
3024 declare this, instead of calling scm_make_subr manually.
3026 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
3028 * readline.h (scm_init_readline): Add prototype for this.
3029 (scm_init_readline): Make this a real prototype.
3031 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3033 Warning fixes from Maciej Stachowiak:
3034 * backtrace.h (scm_display_application, scm_backtrace): Add
3036 * debug.c (scm_m_start_stack): Make this function static.
3037 * fluids.h (scm_fluid_p): Add prototype.
3038 * procprop.c (scm_i_procedure_arity): Make this function static.
3039 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3040 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
3041 * root.h (scm_dynamic_root): Add external prototype.
3042 * scmsigs.h (scm_usleep): Add external prototype.
3043 * script.h (scm_init_script): Use prototype, not K&R decl.
3044 * stacks.h (scm_stack_id): Add external prototype.
3045 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3047 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3049 * gh.h: took out the definitions of vset and vref, since they are
3050 replaced by the proper vector routines that correspond to the R4RS
3053 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3055 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3056 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3057 third argument, a C expression that should result in a SCM value,
3058 which is used to initialize the variable. Reimplemented
3059 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3062 * version.h (scm_libguile_config_stamp): Add prototype.
3063 (From Maciej Stachowiak.)
3065 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3067 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3068 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3070 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3072 * print.c (scm_iprin1): Rather than having one i, and using it in
3073 several places, declare a fresh i local to each block where it is
3074 used, and give it a signedness appropriate to its use in each case.
3075 (scm_iprlist): Same.
3077 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3078 comparison warnings.
3080 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3081 signed/unsigned clashes.
3083 * posix.h (scm_tmpnam): Added prototype.
3085 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3086 scm_make_subclass_object): Add external prototypes.
3088 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3089 comparison is okay here.
3091 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3093 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3094 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3096 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3099 * load.c (swap_port): Make this function static.
3101 * load.c (scm_search_path): Make max_path_len and max_ext_len
3102 unsigned, since they're compared against string sizes.
3104 * load.c (init_build_info): Make i unsigned.
3106 * ioext.h (scm_read_line): Add prototype.
3108 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3109 scm_hash_fn_remove_x): Make hash bucket index local variable k
3110 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3111 accurately as possible.
3113 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3114 comparisons, and range checking to make sure those casts are
3117 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3118 signed/unsigned comparisons.
3120 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3121 avoid signed/unsigned comparisons.
3122 * smob.h (scm_numsmob): Change extern declaration to match.
3124 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3125 avoid signed/unsigned comparisons.
3126 * ports.h (scm_numptob): Change extern declaration to match.
3127 (scm_current_load_port, scm_set_port_line_x,
3128 scm_set_port_column_x): New prototypes.
3130 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3131 test code, and it causes warnings.
3133 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3134 gh_uniform_vector_ref): Added prototypes.
3136 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3137 debugging support unconditionally. That's backtrace.c, stack.c,
3138 debug.c, and srcprop.c.
3139 (EXTRA_libguile_la_SOURCES): Omit those from here.
3140 * Makefile.in: Regenerated.
3142 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3144 * options.c (scm_options): Bugfix: Allow empty list of options!
3146 * debug.c, debug.h (scm_single_step): Removed.
3147 (scm_with_traps): New procedure. This procedure could easily be
3148 written in Scheme but needs to be highly optimized.
3150 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3152 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3153 Check SCM_TRAPS_P before trapping.
3155 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3157 Changes to avoid signed/unsigned comparison warnings.
3158 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3159 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3160 so they can have appropriate types for each application. Make i
3161 signed. Use initializers in some spots. I'll probably pay for
3163 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3164 (scm_must_realloc): Make nm unsigned.
3165 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3166 (scm_init_storage): Use prototype-style definition, and make the
3168 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3169 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3171 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3172 avoid signed/unsigned comparison warnings, and because the return
3173 value of readlink may be -1. Don't bother casting the third
3174 argument to readlink.
3176 * filesys.c (scm_dirname, scm_basename): Move these to their own
3177 page, at the end of the file.
3178 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3180 * eval.h (scm_eval_options_interface): Add external prototype for this.
3181 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3183 * eval.c (scm_lookupcar1): Make this static.
3185 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3186 Make these prototype declarations, not K&R-style.
3188 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3189 unsigned comparison warning.
3191 * appinit.c: File removed. It had a single function in it, empty,
3192 whose reason for existence is explained in no documentation or
3193 comment. I think it's there as a default for some Tcl-style
3194 initialization, but Tcl abandoned that approach a while ago.
3195 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3196 (BUILT_SOURCES): Remove appinit.x.
3197 * Makefile.in: Regenerated.
3199 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3201 * Makefile.in: Regenerated using the last public version of
3202 automake, not the hacked Cygnus version.
3204 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3206 Remove Totoro kludge.
3207 * Makefile.in, scmconfig.h.in: Regenerated.
3208 * init.c, readline.c: Don't check if TOTORO is #defined.
3210 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3212 * Makefile.am: Adjust for new thread configuration system.
3213 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3214 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3216 (THREAD_LIBS): Definition deleted; automake will generate such
3217 things automatically.
3218 * Makefile.in: Regenerated.
3220 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3222 Simplify smob and port marking; set the mark bit in the generic
3223 marking code, and make marker routines only responsible for
3224 turning up outgoing pointers.
3225 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3226 before calling the marking function. Don't call the marking
3227 function if it's zero.
3228 * markers.c (scm_mark0): Just return #f. This function isn't
3229 necessary at all now, but it's harmless to call it. We'll leave
3230 it in so other folks' code doesn't croak at link time.
3231 (scm_markcdr): Don't call SCM_SETGC8MARK.
3232 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3233 * dynl.c (mark_dynl_obj): Same.
3234 * root.c (mark_root): Same.
3235 * srcprop.c (marksrcprops): Same.
3236 * unif.c (markra): Same.
3237 * variable.c (scm_markvar): Same.
3238 * ports.c (scm_markstream): Same.
3239 (void_port_ptob): Specify zero for our marking function.
3240 * debug.c (debugobjsmob): Same.
3241 * dynwind.c (guardsmob): Same.
3242 * filesys.c (dir_smob): Same.
3243 * fluids.c (fluid_smob): Same.
3244 * fports.c (scm_fptob, scm_pipob): Same.
3245 * mallocs.c (mallocsmob): Same.
3246 * regex-posix.c (regex_t_smob): Same.
3247 * smob.c (freecell, flob, bigob): Same.
3248 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3249 * throw.c (jbsmob, lazy_catch_funs): Same.
3251 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3253 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3254 scm_copy_tree on code in order not to let memoized code to leak
3255 out. Thus, scm_copy_tree needs to copy vectors as well since
3256 quasiquote can introduce evaluated code also inside vector
3259 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3261 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3263 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3264 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3267 * unif.c: Say that ivect and uvect are of type signed and unsigned
3268 long instead of int in commentary so that it correctly describes
3271 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3273 * stime.c: Removed declaration of strptime. (It should be
3274 declared by the system headers. If it turns out that some systems
3275 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3277 * stime.h: Renamed TIMEH --> STIMEH
3279 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3280 to increase portability, don't use structure assignment.
3281 (Thanks to Nicolas Neuss.)
3283 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3285 (finalize_fd_sets): Added empty statement after last case label.
3286 (Thanks to Nicolas Neuss.)
3288 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3291 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3293 * init.c, readline.c: OK, I won't have these readline.x bug
3294 reports anymore. We've had them since April. The current reason
3295 is a completely unintelligible failure of totoro.red-bean.com to
3296 do the test for rl_getc_function in libreadline correctly. This
3297 kludge overrides the test if we're on totoro so that the snapshot
3298 generation process can work.
3300 * readline.c: Define a strdup replacement if not existent on system.
3302 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3304 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3305 This change makes scm_make_vector R5RS compatible. We cannot keep
3306 the third argument since people want to be able to deduce the form
3307 of the C function call only by looking at R5RS. (At the same time
3308 we have removed some unnecessary complexity!)
3310 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3311 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3312 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3313 argument in call to scm_make_vector.
3315 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3317 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3318 This macro is useful in applications.
3320 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3322 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3323 (scm_parse_path, scm_search_path): New Scheme level procedures.
3325 * load.h (scm_internal_parse_path, scm_parse_path,
3326 scm_search_path): Declared.
3328 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3330 * filesys.c (dirname, basename): New procedures.
3332 * init.c (scm_boot_guile_1): Removed condition around
3335 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3336 new data type (guards) for representation of C level guards and
3337 data on the wind chain.
3338 (scm_internal_dynamic_wind): New function.
3340 * dynwind.h: Declare scm_internal_dynamic_wind.
3342 * root.h (scm_root_state): Added scm_cur_loadp.
3344 * root.c (mark_root): Added comment about cur_loadp.
3346 * load.c: #include "dynwind.h";
3347 (scm_primitive_load): Use scm_inner_dynamic_wind to update
3350 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3352 * ports.c (current-load-port): New procedure.
3354 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3356 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3357 not a tty, return #f.
3359 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3360 to Julian Satchell and Roland Kaufmann.)
3362 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3363 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3365 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3367 * debug.h, debug.c (scm_start_stack): New function. Implements
3368 the guts of old scm_m_start_stack.
3370 * debug.c (scm_m_start_stack): Use scm_start_stack.
3372 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3373 start_stack and restart_stack. (These have static scope.)
3375 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3377 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3378 readline functions to come in release 2.3. (Thanks to Chet
3380 (handle_errors): Use the above functions.
3382 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3384 * readline.c: Improvements for readline support: Handle errors
3385 better; Implement before-read-hook.
3387 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3389 * init.c (scm_boot_guile_1), readline.c: Test for
3390 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3391 assure that we have version >= 2.1.)
3393 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3395 * readline.c (scm_readline): Defer interrupts while we're calling
3398 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3399 away the string to add_history.
3400 (completion_function): Do completion for readline. (Thanks to
3402 (scm_filename_completion_function): New procedure: Filename
3404 (current_input_getc): New function. Use this one instead of
3405 standard getc from readline.
3407 * throw.c, throw.h (scm_handle_by_throw): New function: This
3408 handler throws errors to next handler on the dynwind chain.
3410 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3412 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3415 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3417 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3419 (scm_procedure_properties): Modified to return arity together with
3421 (scm_procedure_property): Added the read-only property `arity'.
3422 (scm_set_procedure_property_x): It is an error to set the `arity'
3425 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3426 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3428 * procprop.h (scm_sym_arity): New symbol.
3430 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3431 to set the dispatch procedure of an operator or entity object.
3433 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3434 Made procedure slots read-only.
3436 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3437 scm_tcs_cons_gloc case in zero args switch; Fixed args
3438 construction for operators in scm_tcs_cons_gloc case in two args
3441 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3443 * fluids.c: Removed use of assert.h (in order to avoid
3446 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3448 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3450 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3451 change makes the evaluator safer at the cost of evaluation speed.
3452 It handles the case when the user has added a non-immediate
3453 improper end of the application form, e.g., `(+ 0 . x)'.
3454 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3455 minimize the extra cost as much as possible. The new code is
3456 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3457 problem with structs planted directly in the code (e.g. by a
3458 macro). This no longer causes segmentation fault. (Thanks to
3461 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3462 arg `proc' in order to be able to throw errors; New argument
3465 * Removed extra #include "debug.h"
3467 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3469 * scmsigs.c: Declare usleep as returning void on some systems.
3470 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3473 * coop.c (usleep): Return void on some systems.
3475 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3477 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3479 * coop.c: Changed return type of usleep to int.
3481 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3482 isn't found in the OS.
3484 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3485 isn't enabled. (Thought that I had made this change ages ago...)
3487 * iselect.c: Declare bzero if not defined by OS.
3489 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3491 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3492 condition. (Thanks to John Tobey.)
3494 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3495 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3498 * __scm.h: Start the long-term project of moving to POSIX threads.
3499 Phase 1: Classification of all critical sections.
3500 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3501 for A sections. (See comments in __scm.h for details.)
3503 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3504 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3506 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3508 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3509 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3510 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3511 dependencies on $(srcdir)/Makefile.in
3512 $(top_builddir)/config.status in order to avoid circularity.
3514 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3515 from argc if argc was 0 initially.
3517 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3518 in generation of libpath.h.
3520 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3522 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3523 libguile from 2 to 3.
3525 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3527 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3529 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3531 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3532 scm_set_port_column_x, scm_port_filename,
3533 scm_set_port_filename_x): Removed optional arguments. Added
3534 proper argument checking.
3536 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3537 stack size in machine words.
3539 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3540 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3541 to Ole Myren Röhne.)
3543 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3545 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3546 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3548 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3551 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3552 procedure apply: Copy argument lists before pushing them unto the
3553 environment so that the environment won't get mutated due to
3554 manipulation of procedure arguments. This should perhaps be
3555 regarded as a temporary solution until someone finds a more
3556 efficient one. (Thanks to Maciej Stachowiak.)
3558 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3560 * script.c (scm_compile_shell_switches): Use "guile" as default
3561 zero arg if argc is NULL.
3563 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3565 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3566 is zero. (Thanks to Dirk Herrmann.)
3568 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3570 * ports.c (scm_add_to_port_table): First line is now line 0
3571 (was 1). (Interface changed according to suggestion by Per
3574 * backtrace.c (display_header): Add 1 to line and column numbers
3575 when presenting them to the user.
3577 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3578 from debug.c --> eval.c
3580 * eval.h, eval.c (scm_eval_options_interface): New options
3582 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3583 i.e. stacks for new threads.
3585 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3587 * eval.c (unsafe_setjmp): Removed with #if 0.
3589 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3592 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3593 to avoid compiler warnings.
3595 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3597 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3599 * throw.c (handler_message): Print message on current error port
3600 instead of default error port. (Thanks to Maciej Stachowiak.)
3602 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3604 * ports.c (scm_add_to_port_table): allocate in units of
3605 struct scm_port_table *, not struct scm_port_table.
3606 * posix.c (scm_close_pipe): remove the port from the port table
3608 Thanks to Rob Engle for both fixes.
3610 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3612 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3613 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3615 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3617 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3619 * backtrace.c (display_error_body, display_backtrace_body),
3620 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3621 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3622 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3623 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3626 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3627 don't receive the jmpbuf arg anylonger.
3628 (scm_catch): Don't accept a #f tag.
3629 (scm_throw): Check that key is a symbol.
3630 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3632 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3634 * async.c (async_pending): Removed declaration.
3636 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3638 * dynwind.c (scm_wind_chain): New debug function.
3640 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3641 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3642 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3643 extra layer of functions around the body and handler of a thread.
3644 This extra layer makes sure that the handler is called in the
3645 dynamic context of the surround (= empty dynwind list), but under
3646 the *dynamic root* of the body. We can not use the dynamic root
3647 of the surround since that root belongs to another thread => stack
3648 is not handled correctly. It may seem ugly to use this extra
3649 layer, but the extra cost in terms of execution time is really
3650 negligible compared to the total amount of time required to create
3651 a thread, and it would reduce maintainability to duplicate the
3652 crucial and complicated steps performed by cwdr.
3654 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3655 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3656 get re-enabled. The important effect of this is that interrupts
3657 are blocked during thread switching so that thread data structures
3658 don't risk getting messed up by an unfortunate signal.
3659 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3660 seems to do more aggressive optimization which actually move
3661 instructions around in these macros in a fatal way. Therefore:
3662 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3663 just superstitious...)
3664 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3665 This macro should be used instead of SCM_ASYNC_TICK since the
3666 latter doesn't do context switches any more.
3668 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3669 instead of SCM_ASYNC_TICK.
3671 * coop.c, iselect.c: Since thread switches are now performed with
3672 interrupts masked, we can't use the old mechanism of delivering
3673 signals immediately when they arrive. Signals must instead be
3674 delivered when the asyncs run *after* the end of the critical
3675 section in scm_internal_select. But this also means after context
3676 switch so that the signal will be delivered to a different thread.
3677 To avoid this, I have changed the protocol of
3678 coop_wait_for_runnable_thread and friends so that they are allowed
3679 to return the original thread. So, if a signal arrives during
3680 scm_internal_select, we won't any longer be forced do a context
3681 switch, but can remain in the same thread and deliver the signal
3684 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3685 scm_asyncs_pending and made it global.
3687 * iselect.c: Small fixes.
3689 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3690 coop_condition_variable_init, coop_condition_variable_wait,
3691 coop_condition_variable_signal): Changed return type from `void'
3692 to `int'. This is to adhere closer to the pthreads interface.
3693 This, in turn, is part of an attempt to provide C versions of the
3694 mutex and condition variable primitives which can be part of a
3695 frontend to COOP or pthreads.
3697 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3698 coop_condition_variable_destroy): New functions.
3700 * coop-threads.c (scm_wait_condition_variable): Use
3701 coop_condition_variable_wait_mutex.
3703 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3704 Definitions moved to coop-defs.h.
3706 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3707 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3708 scm_cond_destroy): New C interface to mutecis and cond vars.
3710 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3712 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3714 * iselect.c: Now several threads can wait on the same file
3715 descriptor. The behaviour is compatible with OS select: All
3716 threads waiting for the fd return with the same status.
3718 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3720 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3721 Can spawn a thread from application C code.
3723 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3725 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3726 gh_doubles2scm): New functions.
3728 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3730 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3731 commented-out version of gh_eval_str()
3733 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3735 * socket.c (scm_bind): free soka after use.
3737 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3739 * stime.c (tzvar): new variable.
3740 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3741 avoid memory leaks when allocating.
3743 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3745 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3748 * gc.c, tags.h: Doc fixes.
3750 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3752 * eval.c (macro-eval!): Removed. This function was a design bug.
3753 It allowed memoized code to leak out to the scheme level. Most
3754 things that you could do with `macro-eval!' can be done with
3757 1997-12-20 Tim Pierce <twp@skepsis.com>
3759 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3760 scm_fgets now depends on ftell(3) to know how many bytes were
3763 1997-12-15 Tim Pierce <twp@skepsis.com>
3765 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3766 dealing with strings.
3768 1997-12-13 Tim Pierce <twp@skepsis.com>
3770 Make %read-line more suitable for implementing read-line efficiently.
3771 * ioext.c (scm_read_line): Strip the terminating newline from a
3772 string, and return a cons of the string and its terminator.
3774 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3775 of the string that is read is stored in this memory location.
3776 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3777 * genio.c, genio.h (scm_do_read_line): Update caller.
3778 * ports.h (scm_ptobfuns): Update typedef.
3779 * fports.c (scm_fptob, scm_pipob): Update struct.
3781 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3783 * filesys.c (set_element): Return file descriptor.
3784 (fill_select_type): Return the highest file descriptor.
3785 (scm_select): Tell select about the highest file descriptor. On
3786 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3787 Therefore the extra overhead for calculating the maximum fd seems
3788 to be more than compensated. Is this correct? In any case,
3789 scm_internal_select will be much faster with this info.
3790 (scm_select, fill_select_type, set_element): Don't accept any kind
3791 of object in the file descriptor list or vector.
3793 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3795 * iselect.c (finalize_fd_sets): Bugfix.
3797 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3799 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3800 when using scm_internal_select (since we might switch to another
3803 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3805 * simpos.c (scm_system): always define: use sysmissing if not
3806 available. Check for HAVE_SYSTEM instead of _Windows (does
3807 Windows lack system or does it have an unusable one?).
3808 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3809 Let the argument be optional: if not supplied, call system(NULL).
3811 * ports.c (scm_close_port): relax the type check from OPPORTP to
3812 PORTP; closing a closed port is allowed.
3814 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3816 * fports.c (scm_fgets): Return if the last char in a chunk is
3817 newline. When fgets returns a string whose length is `size-1', it
3818 is ambiguous whether a whole line was retrieved, so we must check
3819 explicitly whether a line terminator is present.
3821 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3823 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3824 before taking the CDR. (Thanks to Harald Meland.)
3826 * filesys.c (scm_stat): Slightly optimized.
3828 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3830 * ports.c (scm_close_port): Make sure the port is open before
3833 * guile-snarf.in: Pass args through to gcc in a way that preserves
3834 whitespace boundaries. (Thanks to Greg Badros.)
3836 1997-12-02 Tim Pierce <twp@skepsis.com>
3838 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3839 statement. (Thanks to Doug Evans for pointing this out.)
3841 1997-12-01 Tim Pierce <twp@skepsis.com>
3843 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3845 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3847 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3848 errno macro expansion of this field name. (errno is a C
3849 preprocessor macro on some systems.)
3851 1997-11-29 Tim Pierce <twp@skepsis.com>
3853 * iselect.c: Doc fix.
3855 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3857 * init.c (scm_start_stack): Removed initialization of
3858 scm_the_last_stack_var.
3860 * backtrace.h: Declare scm_the_last_stack_var.
3862 * backtrace.c: Define scm_the_last_stack_var.
3864 * root.c (mark_root): Don't mark the_last_stack_var.
3866 * root.h (scm_root_state): Removed the_last_stack_var.
3868 * throw.c: Added #include "fluids.h"
3869 (ss_handler): `the-last-stack' is now a fluid.
3871 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3872 --> the_last_stack_fluid.
3874 * backtrace.c: Added #include "fluids.h"
3875 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3876 (scm_backtrace): `the-last-stack' is now a fluid.
3878 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3879 after scm_init_fluids.
3881 1997-11-28 Tim Pierce <twp@skepsis.com>
3883 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3885 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3886 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3888 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3890 * iselect.c (coop_next_runnable_thread,
3891 coop_wait_for_runnable_thread): Disable interrupts so that no
3892 async is executed before a potential error_revive.
3893 (scm_internal_select): Disable interrupts during the parts of the
3894 code which manipulate the sleep queue and the file descriptors.
3896 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3898 * Makefile.am: Added iselect.c and iselect.h.
3900 * coop.c (coop_qinit): Initialize fields used by
3901 scm_internal_select.
3902 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3903 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3904 replacement in iselect.c.
3905 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3906 coop_join): If GUILE_ISELECT enabled, use
3907 coop_wait_for_runnable_thread instead of
3908 coop_next_runnable_thread.
3909 (usleep, sleep): New replacements for system functions if
3910 GUILE_ISELECT is enabled.
3912 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3914 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3916 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3917 iselect.h. Implement Scheme level `select' using
3918 scm_internal_select. (See NEWS.)
3920 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3922 * init.c: Call scm_init_iselect.
3924 * iselect.h, iselect.c: New files. Implements
3925 scm_internal_select. (See NEWS.)
3927 1997-11-27 Tim Pierce <twp@skepsis.com>
3929 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3930 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3931 and scm_must_free, since ultimately the string returned will be copied
3932 by scm_makfrom0str anyway. Also, read any characters that may have
3933 been pushed onto the port with scm_ungetc.
3934 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3935 * ioext.c (scm_read_line): Free string after Guilifying it.
3936 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
3938 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3940 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3942 * gh.h: Safely wrap prototypes for c++ usage.
3944 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3946 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3947 gh_repl (argc, argv).
3949 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3951 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3952 and to invoke scm_shell().
3953 (gh_launch_pad): took out the loading of boot-9.scm from here,
3954 since it is probably best to let the user control that. In fact,
3955 gh_repl() now invokes scm_shell() which does that.
3957 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3959 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3962 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
3964 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
3965 yesterday's underscore patch. (Thanks to Marius Vollmer for
3968 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
3970 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
3971 DLSYM_ADDS_USCORE is not defined.
3973 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
3975 * gh_data.c (gh_uniform_vector_length):
3976 (gh_uniform_vector_ref): started implementing the uniform types in
3979 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3981 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3982 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3984 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3986 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3987 configure.in was changed).
3989 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3991 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3992 * Makefile.in: Regenerated.
3994 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3996 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3997 OPORT is an `open' port, not an output port.
3999 * filesys.c (scm_close, set_element, get_element, scm_chown,
4000 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
4001 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
4002 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
4003 scm_close_port, scm_port_line, scm_set_port_line_x,
4004 scm_port_column, scm_set_port_column_x, scm_port_filename,
4005 scm_set_port_filename_x, scm_port_mode,
4006 scm_close_all_ports_except, scm_set_current_output_port,
4007 scm_set_current_error_port): Likewise
4008 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
4009 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
4011 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
4012 * backtrace.c (display_backtrace_body): Likewise
4013 * fports (scm_setvbuf): Likewise
4014 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
4015 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
4016 scm_getpeername, scm_send, scm_sendto): Likewise
4017 * unif.c (scm_uniform_array_write): Likewise
4019 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
4021 Minor problems with substring-related tag changes.
4022 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
4023 exactly what we want to leave in to detect substrings.
4024 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
4025 * tags.h: Fix diagrams and comments describing the S tag bit;
4026 remove vestigial remarks about the D tag bit.
4027 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
4028 * strings.c: Formatting tweaks.
4030 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
4031 variable first; then SCHEME_LOAD_PATH, with a warning message.
4032 (scm_parse_path): New function.
4033 * script.c: Doc fixes.
4035 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
4037 Readline support, from Daniel Risacher.
4038 * readline.c, readline.h: New files.
4039 * init.c: #include "readline.h".
4040 (scm_boot_guile_1): Call scm_init_readline, if we have it.
4041 * Makefile.am (libguile_la_SOURCES): Include readline.c.
4042 * Makefile.in: Regenerated.
4043 * scmconfig.h.in: Regenerated, after change to ../configure.
4045 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4047 * gh.h: gh_vector_set -> gh_vector_set_x
4049 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4051 * gh_data.c (gh_vector_set_x): changed name to make it consistent
4052 with the ! -> _x mapping when going from Scheme to C.
4054 1997-10-19 Mark Galassi <rosalia@cygnus.com>
4056 * gh.h (gh_reverse):
4064 (gh_assoc): added these gh_ functions implemented as macros.
4066 * gh_predicates.c (gh_null_p):
4067 (gh_string_equal_p): added these two missing predicates.
4069 * gh_list.c (gh_append):
4074 (gh_set_cdr_x): added these routines as I go through and try to
4075 complete the picture R4RS functions that should be mirrored in the
4078 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4080 * tags.h (scm_tc7_substring): Changed the comment and code to
4081 conform with the changes below. Folks! We have suddenly two new
4082 free tc7 codes!!! Jummy, jummy!
4084 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
4086 * Makefile.in: Rebuilt.

4107 (scm_tc7_mb_string): Removed.
4108 (scm_tc7_mb_substring): Removed.

4111 Don't include "mbstrings.h".
4112 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
4113 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
4115 Don't include "mbstrings.h".
4116 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
4117 (SCM_SYMBOL_SLOTS): Define as 4.
4118 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
4119 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
4120 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,

4139 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
4140 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
4142 1997-10-12 Mark Galassi <rosalia@cygnus.com>
4144 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
4146 * gh_test_c.c (c_vector_test): some improvements on the vector
4149 * gh.h (gh_vector): this used to exist but do the wrong thing.
4150 Now it (almost) does the right thing, though it takes a list
4151 instead of the individual arguments. I need to see how it could
4153 (gh_list_to_vector): added this function as a macro. Corresponds
4154 to Scheme's (list->vector ...).
4155 (gh_vector_to_list): added this function as a macro. Corresponds
4156 to Scheme's (vector->list ...).
4158 * gh_data.c (gh_vector_ref): renamed from gh_vref to
4159 gh_vector_ref, so that it resembles the Scheme routines more.
4160 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
4161 resembles the Scheme routines more.
4162 (gh_make_vector): this used to be (stupidly) called gh_vector().
4163 This is the right name, since it does the same thing as the Scheme
4164 (make-vector ...) procedure.
4166 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4168 * ports.h: #include "libguile/print.h"
4170 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
4171 Some indentation fixes.
4173 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
4174 longer a user field; New field: class_flags.
4176 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
4178 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
4180 * gh_data.c (gh_bool2scm): new function which replaces
4181 gh_int2scmb(), which is now tagged as obsolete.
4183 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4185 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4186 macros should by convention not test for NIMPness.)
4187 (SCM_COERCE_OPORT): Adjust indentation.
4189 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4190 SCM_NIMP test before SCM_PRINT_STATE_P.
4192 * struct.c, struct.h, gc.c: Renamed:
4193 scm_struct_i_layout --> scm_vtable_index_layout
4194 scm_struct_i_vcell --> scm_vtable_index_vcell
4195 scm_struct_i_vtable --> scm_vtable_index_vtable
4196 scm_struct_i_printer --> scm_vtable_index_printer
4197 scm_struct_i_vtable_offset --> scm_vtable_offset_user
4199 * struct.c (scm_print_struct): Use new printer slot; Default
4200 printing: Also output hex code of vtable so that type identity
4201 will be indicated as well.
4202 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4203 Removed struct_printer_var; Removed struct-vtable-offset;
4204 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4205 vtable-offset-user): New constants.
4207 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
4208 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
4209 If this slot contains a procedure, use that to print structures of
4210 the type represented by this vtable.
4212 * print.c (scm_iprin1): Don't print arguments of macro
4213 transformers. (They are always: exp env.); Bugfix: Unmemoize
4214 transformer source with correct environment.
4216 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4218 Streamlining of call-with-dynamic-root:
4220 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
4221 there is now only one catch.
4222 (cwdr_outer_body): Removed.
4223 (cwdr_handler): New function.
4224 (scm_internal_cwdr): New function to perform the function of cwdr
4225 but take args that are more useful to C code. Also, the handler
4226 is now invoked *outside* of the new dynamic root, like the docs
4227 say. We no longer have to catch absolutely all errors, the caller
4228 is responsible for using a handler that does not throw, if he
4230 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4231 * root.h (scm_internal_cwdr): New prototype.
4233 Even more but risky streamlining:
4235 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4236 allocation of the jumpbuf of a root continuation. The changes
4237 below are controlled by it. They are now deactivated.
4238 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4239 the JMPBUF of the scm_rootcont to NULL before returning.
4241 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4242 when they are non-NULL.
4243 (scm_gc_mark): Likewise, mark only when non-NULL.
4245 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4246 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4248 * gc.c (scm_done_malloc): New function.
4249 gc.h (scm_done_malloc): New prototype.
4251 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
4252 (struct scm_print_state) [revealed]: New field.
4253 (scm_print_state_vtable): Make visible to the outside world for
4254 type checking purposes.
4255 (scm_valid_oport_value_p): New prototype.
4257 * print.c (scm_valid_oport_value_p): New function to check whether
4258 a certain value is acceptable as a port argument.
4259 (scm_print_state_vtable): New variable.
4260 (scm_free_print_state): Set `revealed' field to false.
4261 (scm_iprin1): Call user supplied closure printer with
4262 scm_printer_apply. Print in the traditional way when there isn't
4263 one or when it returns #f.
4264 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4265 Accept a port/print-state pair in addition to just a port.
4266 (scm_prin1): Don't return the print_state to the pool when it has
4268 (scm_printer_apply): Set `revealed' field of print_state to true.
4269 (scm_init_print): Set scm_print_state_vtable.
4270 (print_state_fluid, print_state_fluid_num): Removed.
4272 * throw.h (scm_handle_by_proc_catching_all): New prototype
4273 throw.c (scm_handle_by_proc_catching_all): New function
4275 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4277 * Makefile.in: Regenerated with automake 1.2c.
4279 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4281 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4282 was looping endlessly.
4284 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4286 * strports.c (scm_eval_string): Don't close the port.
4288 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4289 former returns a nice normal integer. (Thanks to Daniel
4292 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4294 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4295 makefile variable as a build parameter called LIBS. The
4296 build-guile program will use this, for the time being.
4297 * Makefile.in: Regenerated.
4299 Thanks to Shiro Kawai:
4300 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4301 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4304 * Makefile.in: Regenerated with automake 1.2a.
4306 * script.c (scm_compile_shell_switches): If we hit the -c or --
4307 arguments, don't set the car of (command-line) to scm_usage_name,
4308 the prettified name of the guile executable; give it the full
4309 path, the way shells usually handle $0.
4311 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4313 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4314 Scheme-level name `array-map' and renamed `serial-array-map' to
4315 `serial-array-map!'.
4317 * backtrace.c: Introduced exception handlers which now enclose
4318 `display-error' and `display-backtrace' so that error reporting
4319 won't get into infinite loops if an error occurs during displaying
4320 of the error. This can very easily happen with user supplied
4321 print call-back routines.
4323 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4325 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4326 the names `serial-array-map' and `array-map' should be removed.)
4328 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4330 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4331 Added #include "objects.h"
4333 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4334 Add #include "feature.h".
4336 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4337 (modinclude_HEADERS): Added objects.h.
4339 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4340 This test is needed at many places in the code and should be
4341 abstracted. (Motivated by the need of this test in libguiletk.)
4343 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4344 (scm_eval_string), load.c (scm_primitive_load,
4345 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4346 Use SCM_EOF_OBJECT_P.
4348 * eval.c (scm_init_eval): Add feature `delay'.
4350 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4352 * scmhob.h: Removed.
4354 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4356 * list.h (SCM_LISTn): New macros. Make list creation in C code
4357 prettier. The idea comes from STk.
4359 * sequences.h, sequences.c, append.h, append.c: Removed. These
4360 files implemented non-R4RS operations which would encourage
4361 non-portable programming style and less easy-to-read code.
4363 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4366 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4367 sequences.h, #include append.h.
4369 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4372 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4374 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4376 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4378 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4380 * eval.c: Added #include "objects.h"
4382 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4385 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4386 adjacent smob numbers.
4388 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4390 * procprop.h: Added declaration of scm_i_inner_name.
4392 * gsubr.c: New global symbol scm_i_inner_name.
4394 * debug.c (scm_procedure_name): Try procedure property
4395 `inner-name' if `name' fails.
4397 * print.c (scm_iprin1): Use scm_macro_name.
4399 * eval.c (scm_m_define): Give names to macros as well; Only the
4400 first top-level definition gives a procedure/macro a name.
4401 Otherwise confusing names can turn up in backtraces.
4402 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4403 `name'; Give names to macros as well.
4405 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4406 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4409 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4411 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4413 (prinmacro): Removed. The code has been moved/merged into print.c
4414 in order to decrease code redundancy. We want macros to print in
4415 a way equivalent to procedures, and it would be silly to duplicate
4416 the required code. (We don't want to maintain two places.)
4417 (macrosmob): Print field is now a NULL pointer.
4419 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4420 scm_macro_transformer): New prototypes.
4421 (scm_tc16_macro): Declared.
4423 * print.c (scm_iprin1): Added code for printing of macros. Macros
4424 are now printed in a way equivalent to procedures.
4426 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4428 * procs.h (scm_closure_p): Added declaration.
4430 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4432 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4433 Shouldn't pass "heap" as the subr name.
4435 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4437 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4438 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4439 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4440 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4441 SCM_BOOL_T. Any non-false value is true.
4443 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4445 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4446 scm_gensym): Added prototypes.
4448 * symbols.c (scm_gensym): New function. This will speed up
4449 certain types of applications (such as macro systems) which
4450 generate lots of symbols.
4452 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4454 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4456 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4458 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4459 specifier, since (2) or (2 . 3) would cause SEGV.
4460 (scm_transpose_array): more argument checking fixes.
4462 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4464 * Makefile.in: Regenerated.
4466 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4468 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4470 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4472 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4474 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4476 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4477 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4480 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4481 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4482 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4483 scm_array_p, scm_array_rank, scm_array_dimensions,
4484 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4485 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4486 scm_array_prototype): Added case scm_tc7_wvect.
4488 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4490 * errno.h: prototype for scm_strerror.
4491 * error.c (scm_strerror): new procedure.
4493 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4495 * list.c (scm_list_append_x): Allow non-pair as last argument.
4496 This is consistent with the R4RS append and is probably the
4497 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4499 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4501 * stime.h: prototype for scm_times.
4502 * stime.c (scm_times): new procedure.
4503 * ioext.c (scm_fseek): if the first argument is a file descriptor
4505 (scm_ftell): if the first argument is a file descriptor call lseek
4507 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
4508 * filesys.c (scm_chmod): if the first argument is a file descriptor,
4510 (scm_chown): if the first argument is a port or file descriptor,
4512 (scm_truncate_file): new procedure.
4513 Add DEFER/ALLOW INTS to a few other procedures.
4514 (scm_fsync): new procedure.
4515 (scm_open_fdes): new procedure.
4516 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
4518 (scm_fcntl): the first argument can now be a file descriptor. The
4519 third argument is now optional.
4521 * posix.c (scm_execl, scm_execlp): make the filename argument
4522 compulsory, since omitting it causes SEGV.
4523 (scm_sync): return unspecified instead of #f.
4524 (scm_execle): new procedure.
4525 (environ_list_to_c): new procedure.
4526 (scm_environ): use environ_list_to_c. disable interrupts.

4532 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4533 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4534 argument to SCM_ASSERT. Furthermore, the name of the function
4535 should be passed as first argument when signalling
4536 SCM_WNA. (Thanks to Thomas Morgan)
4538 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4539 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4540 dispatches on the number of actual args has a default case
4541 reporting an internal error. This is a vestige from a version
4542 that mallocated a SCM vector to hold the arguments. In the
4543 current version this check is too late: if it ever happens we will
4544 have already overstepped the bounds of the array.
4546 Also, the patch [...] adds a check for too many actual arguments."
4548 mdj: Removed check for "internal programming error".
4550 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4552 * gh_io.c (gh_write): New function.

4567 fold in the functionality of scm_primitive_dup.
4568 (scm_primitive_dup): deleted.
4570 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>

4592 (scm_iprin): If print_state_fluid carries a print_state, use that
4593 instead of creating a new one.

4610 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
4611 SCM_ASSERT: arg comes before pos.
4613 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4615 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied

4640 stream has been set.
4641 (scm_duplicate_port): deleted, there's now an implementation in

4694 data. (dynl_smob): Use it.
4695 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4696 the dynamic object data below the linking of the object to avoid
4697 memory leak when the linking code throws an error. Now the code
4698 leaks a whole dynamically linked library when must_malloc throws,
4699 but that should be much less likely.
4701 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4703 Changes to compile under gnu-win32, from Marcus Daniels:

4719 (scm_setpwent): For setpwent.
4720 (scm_setegid): For setegid.

4741 think this is left over from the (eq? '() #f) days.
4743 * read.c (recsexpr): Give this a dummy definition if
4744 DEBUG_EXTENSIONS isn't #defined.
4746 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

4763 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4765 * simpos.h: prototype for scm_primitive_exit.

4773 have to do this explicitly. Also, if regexp/basic is supplied, then
4774 turn off REG_EXTENDED.
4775 (scm_init_regex_posix): New regexp/basic symbol.
4776 (REG_BASIC): #define this if it is not already present.

4795 flag; I don't think we support it.
4796 (scm_make_regexp): Make sure the user doesn't pass the
4799 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4801 (scm_init_regex_posix): Define constants for the REG_mumble flags;

4819 * root.c: Establish a reliable catch-all handler for the new root.
4820 After all the Scheme handler function might signal an error too,
4821 and we don't want to lose that.
4822 (cwdr_inner_body): Renamed from cwdr_body.
4823 (cwdr_outer_body): New function, to establish the user's handler,
4824 and pass control to cwdr_inner_body.

4826 control to cwdr_outer_body.
4827 (struct cwdr_body_data): New field, handler, to allow cwdr to pass

4836 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4837 the feeling that real thread systems will not need this...
4839 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4841 Try to detect when people are using one version of libguile and a

4853 primitive definitions under their Scheme names.
4855 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4856 1:2. Helps avoid confusion between installed and uninstalled libs.
4858 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4861 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4862 backslash from definition; this should be used like: GDB_INTERFACE;
4864 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4866 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
4867 new port unbuffered until its stream has been set.
4869 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4871 * ports.h: new prototype.

4881 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4883 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4884 argument plain char *.
4885 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
4887 * tag.c (scm_tag): Remove unreachable statement.
4888 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4889 top of the word, it should be unsigned.
4891 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4892 is defined, to avoid warnings; it's only used in the
4893 conflict-checking code. Which might go away anyway.
4894 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4895 conditionals; put the label definition in an #if too, to stifle
4898 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4899 ChangeLog-threads in the distribution.
4900 * Makefile.in: Regenerated.

4910 * load.c (scm_init_load_path): Append $(datadir)/guile to
4911 %load-path, so modules do not have to be installed in Guile's
4912 current version directory.
4914 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4916 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4917 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4918 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
4919 call the sysdep functions with deferred ints.

4940 condition during lookup (when using threads).
4941 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4942 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4945 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4947 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4948 supplied. (Change from Tim Pierce.)
4950 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4952 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4953 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4954 default and not `()'. `#f' is the canonical non-value in Scheme,
4957 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4959 * struct.c (struct_printer): New variable that holds a handle on
4960 the Scheme variable *struct-printer*. This variable can be set by
4961 Scheme code to override the printing of structures.
4962 (scm_print_struct): If struct_printer is set, call it. If it is
4963 not set, or returns #f, print the structure in the old fashion.
4964 Include "eval.h" for scm_apply.
4966 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4968 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4969 scm_struct_i_n_words to get the number of fields, not
4970 -scm_struct_n_extra_words.
4972 On the route to fancier struct printing:
4973 * struct.c (scm_print_struct): New function to print a structure.
4974 Include "genio.h" to support it. This function doesn't do
4975 anything interesting right now, but I think it should be here
4977 * struct.h: Include "print.h" and add prototype for
4979 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4980 print structures ourself.
4982 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4984 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4985 before applying the handler in case it doesn't return.
4987 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4989 * scmsigs.h, async.h: updated.
4991 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4994 * posix.c (scm_uname): interpret only negative values as an error.
4995 Solaris normally returns a positive value.
4997 * script.c (scm_compile_shell_switches): if we are not going into
4998 an interactive repl, set scm_mask_ints to zero so that asyncs can
5001 * simpos.c (scm_system): don't ignore/unignore signals around
5004 * posix.c (scm_open_pipe): don't ignore/unignore signals around
5007 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
5008 done in boot-9.scm instead.
5010 * scmsigs.c, async.c: Major rewriting of signal handling code.
5011 (scm_sigaction): new procedure.
5012 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
5014 (scm_raise): return unspecified, throw error on failure.
5016 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5018 * regex-posix.c (scm_init_regex_posix): Register the "regex"
5019 feature, to help boot-9.scm decide whether to import the regex
5022 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5024 * eval.c: Include scmconfig.h at the beginning of the file so that
5025 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
5028 * regex-posix.c: #include "_scm.h" before conditionally #including
5029 <regex.h>; the former defines HAVE_REGCOMP.
5031 * regex-posix.c: #include <regex.h> conditionally, so the file is
5032 CPP'able (for dependency scanning) even on systems that don't have
5035 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5037 Add new R4RS-compliant syntax for keywords.
5038 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5039 regardless of the setting of the `keywords' read option.
5040 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5041 can be re-read no matter what the setting of the `keywords' read
5044 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5046 Add support for POSIX regular expressions.
5048 * regex-posix.c, regex-posix.h: New files. (Some code
5049 is taken liberally from rx/rgx.c in the old Guile dist.)
5051 * init.c: Include regex-posix.h.
5052 (scm_boot_guile_1): Call scm_init_regex_posix.
5054 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5055 Add regex-posix.[ch] sources.
5056 * Makefile.in: Regenerated.
5058 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5059 to do this automatically? It didn't for me, bleh.)
5061 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5063 * fports.c (print_pipe_port): New function.
5064 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5065 latter doesn't even take the right arguments.
5067 * Makefile.am: Increment shared lib revision number. I think
5068 sometimes the uninstalled Guile finds the installed shared lib;
5069 Gord says doing this might help. As things turned out, I can't
5070 say whether it does.
5071 * Makefile.in: Regenerated.
5073 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5074 passing it as the closure argument to scm_boot_guile. (Bill
5077 * ports.c (print_void_port, putc_void_port, puts_void_port,
5078 write_void_port, flush_void_port, getc_void_port, close_void_port,
5079 noop0): Use ANSI prototypes instead of K&R declarations, so the
5080 initialization of void_port_ptob gets aggressively type-checked.
5081 Fix arguments of print_void_port and write_void_port. (Bill

5115 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5117 * script.c (scm_find_executable): Use prototype-style definition
5118 here; apparently it's not quite right to have const in a prototype
5119 and then use a K&R declaration. I wonder if stuff like this will
5120 go away if we compile with -Wrequire-prototypes, or whatever that
5121 is... (Bernard URBAN)
5123 * scmhob.h: New text from Bernard URBAN.
5125 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5127 * script.c: Don't #define const on hpux. Configure takes care of
5128 this. (Thanks to Larry Schwimmer.)
5130 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5131 decide whether to #include <unistd.h>, instead of listing a bunch
5132 of systems. Don't #include stdio twice. Removed dyked-out
5133 definition of scm_find_impl_file.
5135 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5137 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5138 library version info to 1:0.
5139 * Makefile.in: Regenerated.
5141 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

5145 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5146 throw.c: Update copyright years; these files have been worked on
5147 significantly in 1997, but only had copyright years for 1996.
5148 Also, change name of copyright holder on some from Mikael
5149 Djurfeldt to Free Software Foundation; he has signed papers
5150 assigning the changes to the FSF.
5152 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5153 reason not to give the user the option.
5155 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5156 Return #f on end-of-file when scanning table (i.e. when called
5157 with no arguments). Try to catch errors, when we can.
5158 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5160 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5161 external declarations. These are useful.
5163 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5165 * posix.c: don't include <sys/select.h> or define macros for
5166 select, since they were not used in this file.
5168 * filesys.c (scm_select): make the fifth parameter microseconds,
5169 not milliseconds. let the fourth parameter be either a real value
5170 or an integer or #f. The first, second and third arguments can
5171 now be vectors: the type of the corresponding return set will be
5173 (set_element, get_element): new static procedures.
5175 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5177 * strports.c (scm_eval_string): New function.
5178 (scm_eval_0str): Trivially re-implemented in terms of
5180 * strports.h (scm_eval_string): New extern decl.
5182 * net_db.c (h_errno): Add extern decl for this.
5184 * fports.c (local_pclose): New function.
5185 (scm_pipob): Use it in the initializer here.
5188 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5189 Use a meaningful error message when signalling an error. For
5190 this, scm_gethost must check h_errno rather than errno.
5192 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5194 * Makefile.in: Regenerated, using automake-1.1p.
5196 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5198 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5199 not SCM_UNSPECIFIED.
5201 * script.c (scm_compile_shell_switches): don't append (quit) if
5203 (scm_shell): call scm_exit_status and exit on the result of the
5206 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5208 Ensure that shared substrings are handled properly when passed to
5209 a system call or other foreign function. Many thanks to Tim
5211 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5212 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5213 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5214 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

5216 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5217 (scm_display_error_message): use RO macros when strings may be RO.
5218 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5219 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5220 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

5224 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
5225 scm_strftime), vports.c (scm_make_soft_port): use
5226 SCM_COERCE_SUBSTR to make sure shared substrings are
5229 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5231 * error.c (scm_error): Add newline to error message.
5233 * init.c (scm_init_standard_ports): Doc fix.
5235 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5237 * dynl-shl.c: Completely replaced with new code from Bernard
5240 * script.c (scm_ice_9_already_loaded): New variable.
5241 (scm_compile_shell_switches): Use it.
5243 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5245 * filesys.c (scm_input_waiting_p): add missing third argument to
5248 * stime.c (scm_localtime): copy the result of localtime before
5249 calling gmtime in case they share a buffer.
5250 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5253 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5255 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5257 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5259 * Makefile.am (check-local): New target, which causes 'make check'
5260 to run gh_test_c and gh_test_repl, with some trivial input.
5261 * Makefile.in: Rgnrtd.
5263 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5265 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5268 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5270 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5271 sure how this was supposed to work.
5272 (scm_async_click): don't send SCM_TICK_SIGNAL.
5273 (scm_init_async): don't initialize %tick-thunk.
5275 * the following change doesn't affect the Scheme interface:
5276 gc-thunk is called at the end of garbage collection. however it's
5277 no longer implemented by pretending it's a signal.
5279 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5280 system async corresponding to scm_gc_thunk.
5281 * async.h: declare scm_gc_async.
5282 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5283 gc-thunk directly, instead of going through a signal handler.
5284 (scm_gc_async): new variable, points to the GC system-async.
5285 (scm_init_async): save the GC async as scm_gc_async instead
5286 of using system_signal_asyncs.
5287 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5289 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
5291 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
5292 Don't screw up if we're interrupted.
5293 * Makefile.in: Regeneradet.
5295 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5297 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5299 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5300 we're not using AM_INIT_GUILE_MODULE any more.
5301 * Makefile.in: Reneregated.
5303 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5305 Functions for finding variable bindings, grace à Tim Pierce.
5306 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5307 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5309 Get 'make dist' to work again.
5310 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5311 * Makefile.in: Regenerated, like a surry without a fringe on top.
5313 Changes for reduced Guile distribution: one configure script,
5315 * configure.in, configure: Removed.
5316 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5317 real configure script lives.
5318 * Makefile.in, scmconfig.h.in: Regenerated.
5320 * init.c: #include "script.h", to get prototype for script.c's
5323 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5325 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5326 scm_must_malloc, not raw malloc.
5328 * script.c (scm_compile_shell_switches): Dyke out debugging output
5331 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5333 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5335 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5336 system has them. Hope this is safe. Previously
5337 sys/timeb.h was included if HAVE_FTIME was defined or if
5338 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5339 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5341 * ioext.c (scm_setfileno): add missing third argument to
5342 scm_misc_error call.
5344 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5346 * eq.c (scm_equal_p): Correctly compare strings of different
5347 varieties. (Thanks to Tim Pierce.)
5349 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5351 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5352 #! block comment must occur on a line all by itself.
5354 Move most of the guts of shell command processing into libguile,
5355 so guile.c can be very small (and eventuallly auto-generated. (I
5356 mean, generated mechanically, not self-generated. Hmm.))
5357 * guile.c, script.c, script.h: New source files.
5358 * init.c (scm_boot_guile_1): Call scm_init_script.
5359 * libguile.h: #include "script.h".
5360 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5361 targets, for new executable.
5362 (libguile_la_SOURCES): Mention script.c.
5363 (modinclude_HEADERS): Add script.h.
5364 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5365 not dynamic linking is enabled. This is because we're generating
5366 executables now. Move CY_AC_WITH_THREADS call after those, so the
5367 values of cy_cv_threads_libs captures the libs chosen above.
5368 * Makefile.in, configure, aclocal.m4: Regenerated.
5370 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5371 We don't maintain this interface any more, and it just confuses
5374 * alloca.c: #include <scmconfig.h>, not <config.h>.
5375 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5376 it'll get included in disties.
5378 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5380 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5381 be distributed, because they confuse people.
5382 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5384 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5386 * configure.in: check for presence of gethostent (not present on
5387 OpenBSD by default).
5388 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5389 * configure, scmconfig.h.in: Regenerated.
5391 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5393 * backtrace.c (scm_backtrace): Split message string across
5394 newlines properly. GCC is more tolerant of this than other
5397 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5399 Merge threads directory into libguile.
5400 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5401 threads.h: New source files.
5402 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
5403 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5405 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5406 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5407 coop-threads.c.cygnus, coop-threads.h.cygnus.
5408 * configure.in: If we're using threads, include threads.o in
5410 * _scm.h, libguile.h: threads.h lives in this directory now.
5411 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5412 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5413 currently used, but brought along for information's sake.
5414 * ChangeLog-threads: log from old 'threads' directory.
5415 * Makefile.in, configure: Rebuilt.
5417 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5419 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5422 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5424 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5426 Merge GH interface library into libguile.
5427 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5428 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5429 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5430 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5432 (EXTRA_libguile_la_SOURCES): ... here.
5433 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5434 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5435 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5436 New variables, describing how to build the gh test programs.
5437 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5438 build the test programs, and we probably should have been linking
5439 libguile.la against them all along, to support AIX shared libs.
5440 Add cflags for threads to CFLAGS; add libs for threads to new
5441 variable THREAD_LIBS, used in Makefile.am.
5442 * ChangeLog-gh: log from old `gh' subdirectory.
5443 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5445 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5447 * acconfig.h: Undo change of Apr 9; including the definition of
5448 PACKAGE in the guile headers conflicts with applications' own
5450 * scmconfig.h.in: Regenerated.
5452 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

5461 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5463 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5464 have S_IFSOCK. This is the case under Ultrix.
5466 * posix.c (scm_status_exit_val, scm_status_exit_val,
5467 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5468 Ultrix versions of WIFSTOPPED, etc., which assume that their
5469 arguments are lvalues (hmm).
5471 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5473 * eval.c: Doc fixes.
5475 * throw.c: Doc fixes; rearranged.
5477 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5479 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5481 * acconfig.h: Added entry for PACKAGE.
5482 * scmconfig.h.in: Regenerated.
5484 Changes to work with automake-1.1n, which has better libtool support.
5485 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5486 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5488 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5490 * Makefile.in: Rebuild.
5492 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5494 * stime.c (scm_mktime): take an optional zone argument.
5495 (scm_localtime): check putenv return value.
5496 (scm_strftime, scm_strptime): moved from posix.c. move #include
5498 stime.h, posix.h: update prototypes.
5499 (bdtime2c, setzone, restorezone): new static procedures.
5500 (scm_mktime, scm_strftime): use them.
5501 (scm_strftime): don't call mktime before strftime. Use
5502 filltime for return value.
5503 (filltime): convert NULL zname to #f.
5504 (scm_strptime): return a count of characters consumed, not
5505 the remaining string.
5507 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5509 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

5512 Uncomment localtime and mktime.
5514 * configure.in: add AC_STRUCT_TIMEZONE.
5516 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5518 * stime.c (scm_init_stime): don't define ticks/sec.
5519 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5520 return value problem and is still portable.)
5522 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5524 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5525 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5526 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5527 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5528 cpp_err_symbols.c): Corresponding changes.
5529 * Makefile.in: Regenerated.
5531 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5533 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5534 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5535 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5536 * putenv.c: new file, from sh-utils 1.12.
5538 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5539 since allocation isn't for Scheme objects.
5540 (scm_putenv): copy strings before placing in the environment.
5542 * stime.c (scm_current_time): throw an error if time returns -1,
5543 instead of returning #f.
5544 (scm_get_internal_real_time, scm_get_internal_real_time): use
5545 scm_long2num for return value instead of SCM_MAKINUM.
5547 * stime.h: prototypes updated.
5549 * stime.c (scm_time_in_msec): apparently unused, deleted.
5551 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5553 * configure.in: check for gettimeofday.
5555 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5556 which may be more usefully portable than a gettimeofday interface.
5558 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5560 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5562 * Makefile.in: Regenerated.
5564 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5566 * stime.c (filltime): recovered static procedure.
5567 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5570 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5571 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5573 * posix.c (scm_mknod): split the mode argument into type and perms
5574 arguments, like the extra fields returned by stat.
5576 * fports.c (scm_pipob): set the close, free and print procedures.
5577 (scm_close_pipe): new procedure.
5579 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5580 define them in boot-9.scm
5582 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5584 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5585 wan't defined. Don't include fd.h.
5587 * Previously fd.h was regenerated whenever configure was run,
5588 forcing a couple of files to be recompiled.
5590 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5591 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5592 Check for _fileno as well as _file.
5594 * ioext.c: don't fd.h.
5595 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5598 * Change the stratigy for getting information about errno
5599 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5600 generating lists of symbols during the build process, which will
5601 not always work, include comprehensive lists in the distribution.
5602 To help keep the lists up to date, the "check_signals" and
5603 "check_errnos" make targets can be used.
5605 * configure.in: don't check for a command to extract errno codes.
5606 * Makefile.am: update file lists, remove errnos.list and errnos.c
5607 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5608 check_errnos targets.
5609 (CLEANFILES): remove errnos.c and errnos.list, add
5610 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5611 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5612 * errnos.default: deleted.
5613 * cpp_signal.c: new file.
5614 * cpp_errno.c: renamed from errnos_get.c.
5615 * cpp_err_symbols, cpp_sig_symbols: new files.
5616 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5617 * error.c (scm_init_error): #include cpp_err_symbols instead of
5619 * posix.c (scm_init_posix): don't intern signal symbols. #include
5622 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5624 * strop.c (scm_i_index): allow the lower bound to be equal to the
5625 length of the string, so a null string doesn't always give an error.
5627 * posix.h: new prototypes.
5628 * posix.c (scm_status_exit_val, scm_status_term_sig,
5629 scm_status_stop_sig): new functions, as in scsh. They break down
5630 process status values as returned by waitpid.
5632 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5634 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5635 configure doesn't know about it.
5637 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5639 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5641 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5642 which defines C variables with global linkage.
5644 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5646 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5649 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5651 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5652 has time to check why this doesn't work well with continuations.
5654 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5656 * Fix shell syntax error; some shells won't tolerate
5657 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5659 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5661 * posix.c (scm_uname): throw an error if uname fails instead
5664 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5666 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5669 * async.c (scm_ints_disabled): definition moved from error.c.
5671 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5673 * acconfig.h: Removed PACKAGE.
5675 * scmconfig.h.in: Regenerated.
5677 * snarf.h: g++ says it's non-portable not to specify the first
5678 argument in a varargs declaration. I introduced the first
5679 argument by using preprocessor conditionals.
5681 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5683 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5684 (scm_freopen): use RO string macros for filename and modes.
5685 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5687 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5688 (scm_mknod): use RO string macros for path.
5690 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5691 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5693 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5694 use SCM_ROSTRINGP and SCM_ROCHARS.
5696 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5698 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5701 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5702 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5703 support for byte vectors.
5705 * print.c (scm_iprin1): Limit number of vector elements printed
5706 according to pstate->length.
5708 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5710 * backtrace.c (scm_display_error_message): don't segv if message
5713 * error.h: prototype for scm_error_scm.
5715 * error.c (scm_error_scm): new procedure, reimplements scm-error
5716 in C and uses scm_error.
5718 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5720 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5721 pointer to the Scheme variable read-hash-procedures and intern it
5722 in scm_init_read. Modify scm_read_hash_extend and
5723 scm_get_hash_procedure to use the pointer.
5725 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5727 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5728 (SCM_KEYWORD_STYLE): defined.
5730 * read.c (scm_read_opts): add a keywords option. This isn't a
5731 boolean option, in case someone wants to add support for DSSSL
5733 Setup scm_keyword_prefix symbol.
5734 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5736 I've left keyword support disabled by default, since it doesn't
5737 seem to break the module system and it gives R4RS standard behaviour.
5738 It can be reactivated with (read-set! keywords 'prefix).
5740 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5742 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5743 before constructing arbiter.
5745 * eval.c (scm_m_define): Bugfix: Check that the object is a
5746 closure before setting the procedure property!
5748 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5750 * ports.c: Removed `ungetc-char-ready?'.
5752 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5754 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5755 (idea from Mikael: make it a pair so scm_permanent object only
5757 (scm_read_hash_extend): don't call scm_permanent_object.
5758 (ideas from Mikael): if chr is already in the list, replace its
5759 procedure instead of appending it again. If proc is #f, remove
5761 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5763 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5765 * gdbint.c (gdb_read): update scm_lreadr usage.
5767 * load.h: update prototypes.
5769 * load.c (scm_primitive_load, scm_read_and_eval_x,
5770 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5772 * read.h: add prototype for scm_read_hash_extend. Change args for
5775 * read.c (scm_read_hash_procedures): new variable.
5776 (scm_read_hash_extend): new procedure.
5777 (scm_get_hash_procedure): new procedure.
5778 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5779 for extended # processing.
5780 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5781 scm_read_token): remove case_i, sharp arguments. Change callers.
5783 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5785 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5786 (SCM_CASE_INSENSITIVE_P): define.
5788 * read.c: add case-insensitive option to scm_read_opts.
5789 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5790 to determine whether to convert symbol case.
5791 (default_case_i): definition removed.
5792 * read.c (scm_read_token): if case_i, downcase ic before doing
5795 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5797 * configure.in: Added configuration option `guile-debug'.
5798 Configure with --enable-guile-debug if you want a bunch of extra
5799 functions used for debugging when developing Guile.
5801 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5803 * procs.c (make-cclo): New undocumented debugging procedure: Make
5804 compiled closure with internal procedure PROC and length LENGTH.
5805 Only compiled if GUILE_DEBUG is defined.
5807 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5809 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5811 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5813 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5814 with 3 or more args internally to the evaluator.
5816 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5818 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5819 with 3 or more args internally to the evaluator. This is mainly
5820 because we don't want to pass entry and exit points of the
5821 debug support twice, but it also seems to increase the speed of
5822 the evaluator for such calls (e. g. (+ 1 2 3)).
5824 * backtrace.c (scm_display_application): New procedure:
5825 display-application; Set fancy printing parameters individually
5826 for different types of display (backtrace, error, application).
5827 (These should of course be customizable!)
5829 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5830 clear the CHECK-flags.
5832 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5834 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5836 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5838 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5839 from pairs with a GLOC in the car.
5841 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5842 otherwise `symbol-hash' will behave badly.
5843 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5844 we get segmentation fault!
5846 * symbols.c: Added #include "weaks.h". New functions:
5847 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5848 moved to an extraneous library when we split libguile.)
5850 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5852 * filesys.c (scm_stat): stat now takes fport arguments too as
5853 documented in the manual.
5855 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5857 * debug.c (scm_single_step): Bugfix: Call continuation with
5858 scm_call_continuation instead of throwing to it.
5860 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5862 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5863 argument wasn't declared to be optional.
5865 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5867 * stime.c (scm_init_stime): Add feature "current-time".
5869 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5871 * throw.h: prototype for scm_exit_status.
5872 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5873 args to derive an exit status. Allows (quit) to work from a
5875 (scm_exit_status): new function.
5878 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5880 * eval.c (scm_deval): Removed some old code.
5881 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5883 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5886 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5889 * procs.c: Introduce the existent C function scm_thunk_p at the
5890 Scheme level as well.
5892 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5894 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5895 used from C to easily lookup the value of a symbol in the current
5898 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5900 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5901 scm_init_unif in this file. This will also fix a previous problem
5904 * configure.in: Added AM_MAINTAINER_MODE
5906 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5908 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5911 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5913 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5914 source files that are not always included in libguile but should
5915 have their dependencies calculated by automake. This variable is
5916 recognized by automake, no further magic is needed.
5917 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5918 to deal exclusively with *.lo files, as it seems. The *.o files
5919 are built automatically when the corresponding *.lo file gets
5922 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5924 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5927 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5929 * unif.c (scm_array_set_x): minor change to argument error checking.
5931 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5933 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5934 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5935 They should only be included in the library at configure.in's
5937 (libguile_la_LDADD): Include the appropriate .lo files here.
5938 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5939 so we know when to build them (and their .lo bretheren).
5940 * configure.in (LIBLOBJS): New substituted variable. We let
5941 configure decide which .o files to include in LIBOBJS, and then
5942 put the corresponding list of .lo files in LIBLOBJS. The latter
5943 is what we pass to libtool.
5944 * Makefile.in, configure: regenerated.
5946 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5948 * symbols.c (scm_sysintern0): New function. Contains the core of
5949 old scm_sysintern but doesn't take a second value argument.
5950 (scm_sysintern): Now uses scm_sysintern0.
5951 (scm_sysintern_no_module_lookup): Renamed to
5952 scm_sysintern0_no_module_lookup and doesn't take a second value
5953 argument any longer.
5955 * symbols.h (scm_sysintern0: Added declaration.
5957 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5958 scm_sysintern when interning option keys. Otherwise we risk
5959 destroying the values of already interned variables.
5961 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5962 scheme-level boolean (use SCM_NFALSEP).
5964 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5966 (scm_backtrace): New function. (C version of old function from
5967 boot-9.scm) Motivation: Make it possible to display backtraces
5968 without depending on boot-9.scm. (I'm uncertain if this
5969 motivation is good enough...)
5971 * root.h (scm_root_state): Add member the_last_stack_var.
5972 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5974 * root.c (mark_root): Mark scm_the_last_stack_var.
5976 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5979 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5981 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5982 1. mark_lazy_catch didn't mark the smob.
5983 2. Both functions above have standard variants:
5984 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5985 free_lazy_catch --> scm_free0.
5987 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5989 * throw.c (scm_internal_lazy_catch): New function.
5990 (scm_lazy_catch): Rewritten to use it.
5991 (scm_ithrow): Handle the new lazy catch representation.
5992 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5993 that doesn't have a jmpbuf is a lazy catch clause.
5994 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5995 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5996 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5998 (scm_init_throw): Register the new lazy-catch smob type.
5999 * throw.h (scm_internal_lazy_catch): decl for new function.
6001 * throw.c (scm_internal_catch): Doc fixes.
6003 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
6004 configure.in. Including this might cause problems if applications
6005 that link against libguile include their own copies of alloca, but
6006 if they're using autoconf, they should be adding libguile to LIBS
6007 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
6008 the copy in libguile, and things will be okay. (I think.)
6010 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6012 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
6014 strop.h: move prototypes too.
6016 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6018 * posix.c (scm_init_posix): don't intern EINTR since it's now done
6021 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
6022 etc. I deleted them from filesys.c long ago, but didn't
6023 notice they were here too (although ineffective since
6024 sys/stat.h wasn't included).
6026 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
6028 * eval.c: Don't define alloca in GCC case. gcc will automatically
6029 use __builtin_alloca if appropriate.
6031 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6033 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6034 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6035 that values of automatic variables are preserved. See comments
6036 for safe_setjmp for details.
6038 Change from Thomas Morgan:
6039 * variable.c: Include eq.h.
6040 (var_equal): New function.
6041 (variable_smob): Use var_equal as the discriminator for variables.
6043 * throw.c (s_throw): Remove extraneous declaration.
6045 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6046 * eval.c: Add necessary CPP cruft to support that.
6047 * configure, Makefile.in, scmconfig.h.in: regenerated.
6049 Change from Thomas Morgan:
6050 * procprop.c (scm_procedure_properties): Convert the Scheme
6051 boolean returned by scm_procedure_p into a C boolean before using
6052 it as a condition for SCM_ASSERT.
6053 (scm_procedure_property): Likewise.
6055 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6056 indications of Unixness.
6059 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6061 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6063 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6065 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6066 "unknown # object" error messages.
6068 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6069 (scm_i_index) and declare it static. Add a 'direction' argument
6070 to indicate what way the search should go.
6071 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6073 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6074 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6076 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6078 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6080 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6081 to avoid clash with various scsh forks.
6083 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6085 The following two changes (ramap.c, throw.c) are motivated by the
6086 apparent unportability of forward declarations of static arrays of
6087 the form `static foo bar[];'.
6089 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6090 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6092 * throw.c (scm_throw): Moved above scm_ithrow.
6094 * options.h: Removed the extern declarations of scm_yes_sym and
6095 scm_no_sym since these are static.
6097 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6099 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6101 * Makefile.am: remove AWK=@AWK@.
6102 Add a rule for generating errnos.list.
6103 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6105 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6106 don't extract errnos, just set a variable (avoids the
6107 need to recompile error.c just because configure is run.)
6109 * unif.h: update prototypes.
6110 * unif.c (scm_uniform_array_read,write): change the offset and
6111 length arguments to start and end, for consistency.
6113 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6115 * ioext.h: update prototypes.
6116 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6117 scm_read_line_x, it's a more general procedure using an
6118 interface from scsh. read-line and read-line! are now defined
6120 Note that the new read-line trims the terminator
6121 by default, previously it was appended to the returned string. An
6122 optional argument specifies how to process the terminator (scsh
6123 compatible). For the old behaviour: (read-line port 'concat).
6124 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6125 returns a pair, but is converted to multiple values if the scsh
6128 socket.h: update prototypes.
6129 * socket.c (scm_recvfrom): for consistency with other procedures,
6130 take start and end as separate optional arguments.
6131 (scm_recv, scm_recvfrom): don't allow the second argument
6132 to be a size, only a buffer. Change the scheme names to
6133 recv! and recvfrom!. Don't return the buffer.
6135 * ioext.h, posix.h: move prototypes too.
6136 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6137 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6138 "read.h" and "unif.h".
6139 * ioext.c: include "chars.h"
6141 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6143 * dynl.c: The dynamic linking and module registration functions
6144 are now defined even when dynamic linking is not available for the
6145 host system. Some of their functionality can be done without
6146 dynamic linking; when it's really needed, they throw errors.
6148 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6150 * configure.in: Only define DYNAMIC_LINKING when one of the system
6151 dependent functions is detected.
6152 * dynl.c (scm_dynamic_func): New function to get the address of a
6153 function in a dynamic object.
6154 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6155 produced by scm_dynamic_func as the thing to call.
6157 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6159 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6160 (scm_register_module_xxx, scm_registered_modules,
6161 scm_clear_registered_modules): New functions.
6163 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6165 * symbols.c (scm_sysintern): Renamed to
6166 scm_sysintern_no_module_lookup.
6167 (scm_sysintern): New function to take the place of the old
6168 scm_sysintern. It uses the current toplevel lookup closure to give
6169 the symbol its value. This is a temporary hack to put packages
6170 like gtcltk into their own module.
6171 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6172 us whether `scm_top_level_lookup_closure_var' has been initialized
6174 * eval.c (scm_init_eval): Set it.
6176 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6178 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6179 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6181 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6183 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6184 scm_sys_dup): deleted: FD capability will be added to other
6186 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6187 scm_fd_free, fd_smob, scm_intern_fd.
6188 (scm_open): renamed from scm_sys_open. Return a port instead of
6189 an FD object. Make the mode argument optional.
6190 (scm_sys_create): deleted, it's just a special case of open.
6191 (scm_init_filesys): move interning of constants O_CREAT etc.,
6192 here (were previously using SCM_CONST_LONG macro).
6193 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6195 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6196 include "fports.h" and <stdio.h>
6197 (scm_stat, scm_select): don't support FD objects.
6199 * error.h: adjust scm_syserror_msg prototype.
6200 * error.c (scm_syserror_msg): take an extra argument for errno.
6201 Using the global value didn't always work, since it could be
6202 reset by procedure calls in the message or args arguments.
6204 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6205 I don't understand why the check was there (and what about the
6208 * strop.c (scm_string_copy): allow shared substrings to be copied.
6210 * unif.h: corresponding change to prototypes.
6211 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6212 recognize two new optional arguments: offset and length. Allow
6213 the port argument to be an integer (file descriptor, for scsh).
6214 Include <unistd.h> for "read" prototype.
6216 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6218 * socket.c: don't include filesys.h.
6220 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6222 * Makefile.am: add AWK=@AWK@ (?)
6224 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6226 Add a rule to generate errnos.c from errnos.
6227 * error.c (scm_init_error): include errnos.c.
6228 * errnos_cnvt.awk: new file, converts the list of errno codes to
6230 * errnos_get.c: new file.
6231 * errnos.default: new file, contains errnos to try if they can't
6232 be extracted from errno.h.
6233 * configure.in: if using GCC, try and extract errno codes from
6237 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6239 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6240 * Makefile.am: Made libguile into a libtool library.
6241 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6242 Set libtool_libs to indicate that libguile is a libtool library.
6243 See guile/ChangeLog for details.
6244 * .cvsignore: ignore "*.lo", the libtool library objects.
6246 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6248 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6249 use htons in getservbyport argument.
6251 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6253 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6254 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6257 * objprop.c (scm_object_property): No need to take the CDR of the
6258 value returned by scm_object_properties, since Aug 20 change.
6260 * configure.in: When checking for struct linger, #include
6261 <sys/types.h> as well as <sys/socket.h>. I've never known
6262 <sys/types.h> to cause any portability problems, and Solaris's
6263 <sys/socket.h> needs it.
6264 * configure: Rebuilt.
6266 I think the Sun compiler has chosen a perverse way to interpret
6267 ANSI declarations combined with K&R definitions. We'll
6268 appease it a little bit. But when it invades France, we fight.
6269 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6270 * print.h (scm_iprlist): Here too.
6271 * numbers.c (scm_divbigdig): Change definition to match
6272 declaration in numbers.h.
6273 * unif.c (scm_makflo): Change definition to match declaration in
6276 * init.c (scm_boot_guile): Don't return the value of
6277 scm_boot_guile_1. This function doesn't return a value;
6278 scm_boot_guile_1 doesn't return a value (or return at all).
6280 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6283 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6284 compile. I have a feeling this function is a bad idea anyway ---
6285 one should always test for features, not systems.
6287 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6288 semicolons. Only pure luck kept this from being noticed earlier.
6290 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6292 * socket.c (scm_recvfrom): Added missing semicolon.
6294 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6296 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6297 the buffer and start and end positions for scsh networking
6300 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6302 * configure.in: Revert previous change to this file; the problem
6303 is due to transient automake weirdness.
6304 * configure: Rebuilt.
6306 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6307 PLUGIN/guile.libs. configure generates the latter from the former.
6308 * Makefile.in: Rebuilt.
6310 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6311 need this if we install scripts, like guile-snarf.
6312 * configure: Rebuilt.
6314 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6316 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6318 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6320 * socket.c (scm_addr_vector): fix faulty scm_listify.
6322 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6324 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6325 style block comment is no longer considered an error.
6327 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6329 * PLUGIN/guile.libs.in: New file.
6330 * PLUGIN/guile.libs: Removed from repository.
6331 * configure.in: Create PLUGIN/guile.libs from
6332 PLUGIN/guile.libs.in. This is for including additonal libraries
6333 needed for dynamic linking.
6334 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6335 instead of PLUGIN/guile.libs.
6337 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6339 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6341 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6342 occurrences of the given element from the list, not just the
6343 first. This is how the Emacs Lisp functions behave, how the
6344 analogous Common Lisp functions behave, and (I believe) how the
6345 older Maclisp functions worked. I realize that this change may
6346 break code, but it seemed better to break it before the Guile
6349 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6350 Their prototypes were already present in gc.h, but they weren't
6352 (scm_init_storage): Initialize scm_protects.
6353 * root.c (scm_protects): New element of scm_sys_protects.
6355 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6357 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6359 * libguile.h: Added #include "libguile/net_db.h".
6361 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6362 30 change. That file is only meant for communication between the
6363 configuration process and load.c. If code linked against libguile
6364 wants to get at the paths mentioned in libpath.h, it can call
6365 functions declared in load.h.
6367 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6369 * libguile.h: Removed #include "libguile/fdsocket.h"
6371 * net_db.c: Added #include <sys/socket.h>.
6373 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6375 * filesys.c (scm_input_waiting_p): use select in preference to
6376 FIONREAD, since the latter doesn't detect EOF.
6377 Throw error if neither select nor FIONREAD available.
6379 * socket.c (scm_connect): take a port, not a fd object.
6380 (scm_fill_sockaddr): throw an error if fam is not recognised.
6381 (scm_bind): use scm_fill_sockaddr.
6382 (scm_listen): take a port, not a fd object.
6383 (scm_accept): take and return a port. return #f in the car if
6384 address can't be got
6385 (scm_sock_fd_to_port): new procedure.
6386 (scm_socket): use scm_sock_fd_to_port.
6387 (scm_addr_vector): throw error if unrecognised address type.
6388 take an extra argument with the calling procedure name.
6389 (scm_getsockname): take a port. return #f if address can't be got.
6390 (scm_getpeername): take a port. return #f if address can't be got.
6391 (scm_recvfrom): take a port. return #f for address component if can't
6393 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6394 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6396 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6398 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6399 use separate data pointers, to allow them to be designed
6400 independently and reused.
6401 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6402 Renamed from catch_body, catch_handler, and uncaught_throw; made
6404 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6406 (scm_catch): Use the above.
6407 (scm_throw): Don't bother printing a message for an uncaught
6408 throw; we establish a default handler in init.
6409 * throw.h (scm_internal_catch): Prototype updated.
6410 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6412 (struct scm_body_thunk_data): New structure, used as data
6413 argument to scm_body_thunk.
6414 * init.c (struct main_func_closure): New structure, packaging up
6415 the data to pass to the user's main function.
6416 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6417 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6418 scm_internal_catch to establish a catch-all handler, using
6419 scm_handle_by_message. This replaces the special-case code in
6421 (invoke_main_func): Body function for scm_internal_catch; invoke
6422 the user's main function, using the main_func_closure pointer to
6423 decide what to pass it.
6424 * root.c (struct cwdr_body_data): Remove handler_proc member.
6425 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6426 (cwdr_handler): Removed.
6428 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6430 * socket.h (SCM_P): update bind prototype.
6431 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6432 include "feature.h".
6433 (scm_socket): return a port, not a file descriptor object.
6434 include "fports.h" and <unistd.h>
6435 (scm_bind): take a port, not a file descriptor object.
6436 take an extra argument for address args.
6438 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6439 INADDR_NONE, INADDR_LOOPBACK.
6441 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6443 * init.c: include net_db.h and not fdsocket.h.
6444 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6446 * Makefile.am: corresponding changes.
6447 * socket.h: renamed from fdsocket.h, fix names.
6448 * net_db.h: renamed from socket.h, fix names.
6449 * socket.c: renamed from fdsocket.c.
6450 remove _sys from procedure names.
6451 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6452 add "socket" to features list.
6453 * net_db.c: renamed from socket.c.
6454 remove _sys from procedure names.
6455 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6456 add "net-db" to features list.
6457 include "net_db.h". don't include <sys/socket.h> or
6460 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6462 * tags.h (scm_tags): Removed comma at end of last enumerator.
6464 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6466 Don't use GCC extensions to allocate space for debugging frames.
6467 (Here he goes again! Why do we put up with this?!)
6468 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6469 an scm_debug_info structure, not an in-line array of them. Add
6470 'info' member, to say how many vect elements we've used, for eval
6472 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6473 a new variable debug_info_end to mark the end of vect, instead of
6474 the address of the 'info' pointer itself.
6475 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6476 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6477 (SCM_APPLY): Explicitly allocate space for debug.vect.
6478 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6479 * stacks.c: Adjusted for new debug frame structure.
6480 (RELOC_INFO, RELOC_FRAME): New macros.
6481 (stack_depth, read_frames): Use them, and new scm_debug_frame
6482 element 'info', instead of magically knowing that eval frames have
6483 an info pointer sitting after vect.
6484 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6486 (scm_init_stacks): Formatting tweaks.
6488 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6490 Give GCC more control flow information, so it can be sure that
6491 variables aren't used uninitialized.
6492 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6493 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6494 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6495 scm_misc_error): Tell GCC that these functions never return.
6496 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6497 out the field type, call abort if SCM_ASSERT returns, to placate
6499 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6500 scm_wta ever returns. We can't handle this case anyway, and this
6501 gives the optimizer more information.
6502 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6503 scm_wta ever returns.
6505 In some cases, the code is fine, but GCC isn't smart enough to
6506 figure that out; this usually happens when one variable is only
6507 initialized and used when a particular condition holds true, and
6508 we know that condition will never change within a given invocation
6509 of the function. In this case, we simply initialize the variables
6510 to placate the compiler, hopefully to a value which will cause a
6511 crash if it is ever actually used.
6512 * print.c (scm_iprin1): Initialize mw_pos.
6513 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6514 * throw.c (scm_ithrow): Initialize dynpair.
6515 * unif.c (scm_uniform_vector_ref): Initialize cra.
6516 * struct.c (init_struct): Initialize prot.
6517 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6519 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6520 if EXPR contains no expressions.
6522 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6524 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6525 cause an infinite loop (???). So much for the algebraic
6526 equivalency of variable-sized arrays and alloca...
6528 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6530 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6531 a SCM boolean, not a C boolean.
6533 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6535 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6536 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6537 rules for raising scm_mtrigger. Previously, unfortunate but not
6538 unlikely circumstances could result in almost constant invokation
6539 of the gc. Now, this situations should be less likely, but they
6540 are not prevented completely.
6542 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6544 * numbers.c (scm_fuck): Procedure removed; looks like old test
6546 * numbers.h: Prototype removed.
6548 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6550 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6551 array to a pointer, to match my Nov 21 change in eval.c.
6553 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6555 * libguile.h: Added #include "libguile/backtrace.h", #include
6556 "libguile/stacks.h".
6558 * strings.c (scm_string scm_make_string scm_string_ref
6559 scm_string_set_x scm_string_equal_p scm_string_append):
6560 Bugfix according to scm patch from Aubrey Jaffer:
6561 Corrected long-standing
6562 (not (eqv? (integer->char 128)
6563 (string-ref (make-string 1 (integer->char 128)) 0)))
6564 bug found by John Kozak <jk@noontide.demon.co.uk>.
6566 * strports.c, strports.h: Make scm_eval_0str return the value of
6567 the last expression evaluated (previously, it returned void).
6569 * strports.c, strports.h: New function: scm_read_0str. Does what
6572 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6574 * simpos.c (scm_getenv): return #f if string can't be found in the
6575 environment instead of throwing an exception, for compatibility
6576 with numerous other systems.
6578 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6580 * Makefile.am (.c.x): Use guile-snarf.
6581 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6583 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6585 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6587 * backtrace.c (scm_display_error_message): Made non-static, and
6588 renamed from display_error_message.
6589 * backtrace.h (scm_display_error_message): Added extern decl.
6590 * throw.c (uncaught_throw): Use it to display the error message.
6592 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6594 * inet_aton.c: Use #if 0, not #ifdef 0.
6596 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6598 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6599 to convert the returned value.
6600 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6601 the offset argument.
6603 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6605 Add new interface to catch/throw, usable from C as well as
6607 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6608 (scm_internal_catch): New function, replaces...
6609 (scm_catch_apply): Deleted.
6610 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6611 mechanism which is a bit more code, but can be used nicely from C
6612 and implement the Scheme semantics as well.
6613 (scm_internal_catch): This is the replacement; it's named after
6614 the analogous function in Emacs.
6615 (scm_catch): Reimplemented in terms of the above.
6616 (struct catch_body_data, catch_body, catch_handler): New
6617 functions, used by scm_catch.
6618 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6619 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6620 support for new cwdr.
6622 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6625 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6627 * acconfig.h: Added DYNAMIC_LINKING symbol.
6628 * configure.in: Add option and checks for dynamic linking.
6629 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6630 dynl.h: New files for dynamic linking support.
6631 * Makefile.am (libguile_a_SOURCES):
6633 (modinclude_HEADERS): Added "dynl.h".
6634 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6636 * init.c (scm_boot_guile_1): Call
6637 scm_init_dynamic_linking to initialize dynamic linking support.
6639 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6641 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6642 (as we Schemers say). It needs to be global, so that I can tweak
6643 it for the proper operation of unexec.
6644 (scm_boot_guile_1_live): New variable, see above.
6646 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6648 * guile-snarf.sh: Removed.
6649 * PLUGIN/guile.libs: Added dependency for -lm.
6650 * acinclude.m4: Renamed from aclocal.m4.
6651 * PLUGIN/greet: Removed.
6652 * Makefile.am, aclocal.m4: New files.
6653 * configure.in: Updated for Automake.
6655 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6657 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6658 and not top_level_lookup_thunk_var.
6660 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6662 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6664 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6666 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6667 Scheme function, instead of syntax. Single argument is now a
6670 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6672 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6673 scm_ra_divide): Properly terminate statements passed as arguments
6674 to IVDEP macros. (Thanks to Bernard Urban.)
6676 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6677 with non-constant sizes. (Thanks to Bernard Urban.)
6679 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6681 It's an "eval closure", not an "eval thunk." A thunk is a
6682 function of no arguments.
6683 * root.h (struct scm_root_state): Renamed
6684 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6685 (scm_top_level_lookup_closure_var): Renamed from
6686 scm_top_level_lookup_thunk_var.
6687 * root.c (mark_root): Uses changed.
6688 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6689 * init.c (scm_start_stack): Uses changed.
6690 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6691 Change scheme-visible name to *top-level-lookup-closure* from
6692 *top-level-lookup-thunk*.
6694 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6696 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6697 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6699 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6701 * gc.c (struct scm_heap_seg_data): Doc fixes.
6703 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6704 sweeping. Then, prepend each segment's free cells to its
6705 freelist, rather than wiping out the old value. (Thanks to Marius
6708 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6709 scm_check_freelist, scm_debug_newcell): New functions and
6710 variables, for debugging freelist problems.
6711 * pairs.h (SCM_NEWCELL): New debugging version added.
6712 * gc.h (scm_debug_newcell): Added extern declaration, used by
6713 debugging version of SCM_NEWCELL.
6715 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6717 On some systems <libc.h> conflicts with <unistd.h>, and should not
6718 be #included at all.
6719 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6720 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6721 * configure.in: Call it.
6722 * posix.c, filesys.c: Use its results to decide whether or not to
6724 * configure, scmconfig.h.in: Rebuilt with autoconf and
6727 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6729 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6730 pointer to the stdio stream before calling scm_setbuf0, so the
6731 latter will be able to retrieve it. I'm surprised this didn't
6732 segfault earlier. (Thanks to Christopher Lee.)
6734 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6736 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6739 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6741 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6742 number of stack narrowing specifier pairs. The first specifier in
6743 a pair controls inner border, the second the outer border. A
6744 number means cut that number of frames, a procedure object means
6745 cut until that object is found in operator position in a frame.
6747 * root.c (cwdr): Bugfix.
6749 * read.c: Recording of positions disabled by default.
6751 * procs.c (scm_closure_p): New function.
6753 * posix.c (scm_tmpnam): New function.
6755 * load.c: Added #include "throw.h".
6756 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6759 * load.c, load.h (scm_read_and_eval_x): New function.
6761 * eval.c: Renamed debug option "deval" to "debug".
6763 (scm_eval_x): `eval!' is no longer accessible from the scheme
6764 level. Motivation: We can't allow operations which introduce
6765 glocs into the scheme level. Guile's type system can't handle
6766 these as data. Use `eval' or `read-and-eval!' as replacement.
6768 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6769 SCM_CONSP since this is a macro!; Set vframe.prev to
6770 scm_last_debug_frame instead of 0. In this way we can look
6771 "above" the virtual start stack frame if we wish.
6772 (scm_debug_hang): New function: Useful for debugging Guile in
6773 certain tricky situations. Will probably be removed later...
6775 * debug.h: Changed semantics of debug option "backtrace". This
6776 option now only indicates whether we want automatic backtrace at
6779 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6781 * ports.c: #include "filesys.h"
6782 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6784 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6785 Motivation: This is system specific code which is related to file
6786 I/O. It also may use select. Added code by Gary Houston to
6787 detect presence of character in stdio buffers.
6789 * libguile.h: #include "libguile/libpath.h"
6791 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6792 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6793 SCM_SITE_DIR; Install libpath.h among the other include files.
6795 * load.c, load.h (scm_sys_package_data_dir): New function.
6797 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6799 * stacks.h: Bugfix: Don't use tail-array length field as stack
6800 length field! This screwed GC.
6802 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6804 * _scm.h: Added #ifndef around definition of macros min and max.
6806 * __scm.h: Added hooks for threads to plugin to in ints protection
6807 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6808 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6809 the main code in these macros duplicated and spread over multiple
6810 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6811 SCM_THREAD_SWITCHING_CODE.
6813 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6815 * snarf.h: New file.
6816 * guile-snarf.sh: New file.
6817 * Makefile.in (inner_h_files): Added snarf.h
6818 (ancillary, install, uninstall, distclean): Added actions for
6820 (.c.x): Use guile-snarf.
6821 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6822 (gen_c_files): Note that these depend on guile-snarf.
6823 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6824 now in "snarf.h". Added #include "snarf.h" to get them.
6825 * libguile.h: Added #include "snarf.h".
6826 (Patches applied and tweaked by Jim Blandy.)
6828 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6830 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6831 standards suggest against providing prototypes for system
6832 functions. Thanks to Greg Troxel.
6834 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6836 * strports.c (scm_eval_0str): New function.
6837 #include "read.h", to get prototype for scm_read.
6838 * Makefile.in (strports.o): Update dependencies.
6839 * strports.h: New prototype.
6841 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6842 scheme name from "int?" to "integer?". It seems to do the job.
6843 * numbers.h: Rename prototype too.
6844 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6847 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6848 scm_num_eq_p): Rename these according to R4RS conventions: call
6849 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6850 to making libguile R4RS compliant without ice-9...
6852 * load.c (scm_sys_search_load_path): Search for files under all
6853 extensions listed in the %load-extensions variable. If FILENAME
6854 is absolute, return it unchanged, without searching the load path.
6855 (scm_loc_load_extensions): New variable, pointing to
6856 %load-extensions' value cell.
6857 (scm_init_load): Initialize it, and the value it points to.
6858 (scm_primitive_load_path): Improve error reporting.
6860 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6861 of new Scheme variable %load-hook.
6862 (scm_primitive_load): Apply %load-hook to filename.
6864 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6866 * configure.in: add tests for figuring out whether buffered data
6867 is available in a FILE structure, which is needed by char-ready.
6869 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6872 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6873 exceptions using misc_error instead of syserror. It seems a bit
6874 odd to throw an exception if a string can't be found in the
6875 environment, but it's consistent with open-file, stat etc.
6876 (simpos.h): remove sys_ from getenv.
6878 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6879 occurs, throw an error instead of returning errno. Return value
6881 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6883 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6885 * filesys.c (scm_stat2scm): derive file type and permissions from
6886 the stat mode and append them to the returned vector.
6887 There isn't much overhead in doing this and it avoids the need to
6888 work with S_IRUSR et al. in Scheme.
6889 Define symbols scm_sym_regular etc.
6890 (scm_init_filesys): don't intern S_IRUSR etc.
6892 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6893 and s_primitive_load_path.
6895 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6897 * error.h: don't declare error symbols. prototype for scm_misc_error.
6899 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6902 * error.c: use SCM_SYMBOL to set up error keys.
6903 scm_misc_error: new procedure.
6905 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6907 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6908 between `#!' and `!#' is ignored.
6909 (skip_scsh_block_comment): New function.
6911 * feature.c (scm_set_program_arguments): New argument, FIRST.
6912 * feature.h: Update prototype.
6913 * init.c (scm_boot_guile_1): Pass new argument to
6914 scm_set_program_arguments.
6916 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6918 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6919 (scm_boot_guile): Call scm_set_program_arguments here, later than
6920 the old initialization.
6922 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6923 initialization procedure.
6924 - Delete in, out, err arguments; there are other perfectly good
6925 ways to override these when desired.
6926 - Delete result argument; this function shouldn't ever return.
6927 - Rename init_func argument to main_func, for less confusion.
6928 - Delete boot_cmd argument; main_func is more general.
6929 -Add 'closure' argument, to help people pass data to main_func
6930 without resorting to global variables.
6931 - Abort if reentered; don't bother returning an error code.
6932 - Call scm_init_standard_ports to set up the default/current
6933 standard ports; no need to pass them to scm_start_stack.
6934 - Remove code to evaluate the boot_cmd, and start the repl; let
6935 the user do something like that in main_func if they want.
6936 - Remove code to package up a return value; main_func can do any
6938 - Call exit (0), instead of returning.
6939 (scm_start_stack): Don't initialize the I/O ports here; that's
6940 weird. Delete in, out, err arguments. Move guts to
6941 scm_init_standard_ports, scm_stdio_to_port.
6942 (scm_init_standard_ports): New function, to set up current and
6943 default standard ports.
6944 (scm_start_stack, scm_restart_stack): Make these static.
6945 * init.h (scm_boot_guile): Adjust declaration.
6946 (scm_start_stack, scm_restart_stack): Remove externally
6947 visible declarations for these.
6948 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6950 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6951 written out several times in scm_start_stack.
6952 * fports.h: New declaration for the above.
6954 * feature.c (scm_set_program_arguments): New function.
6955 * feature.h: New declaration for the above.
6957 * ports.c: Formatting tweak.
6959 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6961 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6962 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6963 for obtaining the address of a car or cdr field. Motivation:
6964 &SCM_CXR make assumptions about the internal structure of the
6967 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6968 Motivation: see SCM_CXRLOC.
6970 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6971 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6972 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6973 Motivation: Safer use. Some other macros are defined in terms of
6974 these operations. If these are defined using the SCM_SETCXR
6975 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6976 to inefficiency and an <e1> with side-effects could potentially
6977 break. Also, these particular operations are heavily utilized in
6978 the garbage collector. In unoptimized code there will be a
6981 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6982 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6983 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6984 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6985 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6986 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6987 vports.c: Cleaned up use of pairs: Don't make any special
6988 assumptions about the internal structure of selectors and
6989 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6990 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6991 (Among other things, this change makes it easier to build Guile
6992 with certain compilers which have problems with casted lvalues.)
6994 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6996 * stacks.c: Improve selection of relevant stack frames when making
6997 a stack object. Introduce one level of indirection in the stack
6998 object to make it possible to "narrow" to a certain region of the
6999 stack. This facilitates making use of more clever algorithms (not
7000 implemented) for selecting relevant frames and gives a cleaner
7001 design since selection of frames can be done independently of
7002 extraction of frames from the real stack.
7003 (scm_stack_id): Also take #t as argument which means look at
7006 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
7007 Turn n_tail into an integer directly representing current number
7008 of frames in stack. Add field tail.
7010 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
7012 * debug.c (scm_make_memoized): Made it available at scheme level.
7013 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
7014 SCM_NIMP before applying heavier predicates in argument checking.
7015 (scm_local_eval): Also take memoized object as argument.
7017 * backtrace.c (scm_display_error): Just a safety measure: Stacks
7018 aren't created with zero length, but should such a strange
7019 creature suddenly turn up...
7021 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
7023 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
7024 `del', for the sake of C++ compilers. (Patch applied by JimB.)
7026 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
7028 * variable.c (scm_make_variable): Make the name hint optional, as
7030 (anonymous_variable_sym): Renamed from variable_sym. All uses
7033 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7034 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7035 of scm_primitive_load_path was also changed to
7036 "primitive-load-path", from "%try-load-path". Callers changed.
7037 We'd like to respect the convention that a function named
7038 "try-mumble" should behave just like the function called "mumble",
7039 but return #f instead of signalling some error.
7040 * load.h: Rename prototypes.
7042 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7044 * print.c (make_print_state, grow_print_state), print.h: Modified
7045 the print state representation: Don't use a tail array for
7046 recording of circular references. Resizing of the print state
7047 structure invalidates the print state pointer. To avoid passing
7048 around an indirect print state reference to all printing
7049 functions, we instead let the print state reference a resizable
7052 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7054 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7055 Don't crash when passed an improper list terminated by a
7056 non-immediate value.
7058 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7060 Allocate data for structures on an eight-byte boundary, as
7061 required by the tagging system.
7062 * struct.c (alloc_struct): New function.
7063 (scm_make_struct, scm_make_vtable_vtable): Call it.
7064 * struct.h (scm_struct_n_extra_words): Bump to 3.
7065 (scm_struct_i_ptr): New "field".
7066 * gc.c (scm_gc_sweep): When we need to free the data, use the
7067 information stored by alloc_struct to find the beginning of the
7068 block allocated to the structure, so we can free it.
7070 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7072 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7075 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7076 (scm_debug_info): New member: id.
7078 * stacks.c: Stacks are now represented as structs; Stacks have an
7079 id given to them by `start-stack'.
7080 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7082 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7083 Changed stack representation.
7085 * debug.c (scm_procedure_name): Try procedure property `name' for
7086 compiled closures aswell.
7088 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7090 * eval.c: scm_i_name moved to gsubr.c
7091 (scm_m_define): Record names of all kinds of procedure
7092 objects. (Earlier, only closures were recorded.)
7094 * procprop.h: Added declaration of scm_i_name.
7096 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7097 (scm_make_gsubr): Record names of compiled closures.
7099 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7101 * debug.c, debug.h: Removed obsolete code.
7103 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7104 stacks.c: Renamed regs --> scm_contregs.
7106 * print.c (scm_free_print_state): Cleanup print state before
7107 returning it to pool. It is better to do it here than in
7108 scm_prin1 since scm_prin1 is called often.
7110 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7111 s_set_source_property_x): Check that first argument is a pair or a
7114 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7115 scm_i_line, scm_i_column and scm_i_breakpoint global.
7117 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7118 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7121 * debug.h: Added debug object smob declaration and macro
7124 * configure.in: Build with backtrace.o and stacks.o if debug
7127 * Makefile.in: Added entries for new files: backtrace.c,
7128 backtrace.h, stacks.c and stacks.h.
7130 * symbols.c (scm_sym2ovcell): Fixed documentation.
7132 * _scm.h (min, max): Added.
7134 * async.c: Moved `min' macro to _scm.h.
7136 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7137 SCM_BACKTRACE_INDENT.
7139 * eval.c: Added new debug options `maxdepth' and `indent'.
7141 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7143 * print.h: Added selector SCM_PRINT_STATE.
7145 * print.c: New functions: scm_make_print_state,
7146 scm_free_print_state.
7148 * print.h: Added declarations for scm_make_print_state,
7149 scm_free_print_state.
7151 * debug.c (scm_m_start_stack): New acro.
7153 * debug.h: Small cleanup.
7155 * init.c (scm_boot_guile_1): Moved scm_init_debug below
7158 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

7178 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
7179 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
7180 declare functions with prototypes. (Patch thanks to Marius
7183 More prototype-related changes from Marius Vollmer:
7184 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7185 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7186 * ports.h (ptobfuns): Added prototypes. This means some casting in
7188 * fports.c: Added casts for initializations, since the functions
7189 are defined to take FILE * as their stream argument, not SCM.
7190 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7191 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7192 to `char *str_data' to conform to prototype.
7194 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7196 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7198 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7200 * stime.c, stime.h: use SCM_P method.
7202 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7204 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7205 be given at least two arguments. Insist that lst's last element
7206 be a list, but don't make any requirements of its predecessors.
7208 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7210 * eval.c (scm_nconc2last): Revert last change; there seems to be
7211 other stuff going on here.
7213 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7215 * eval.c (scm_nconc2last): Make sure that each element of lst
7216 (which is a list of argument lists, except for the tail) is a
7217 proper list, i.e., finite and terminated by '().
7219 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7221 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7224 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7225 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7228 * vectors.c (scm_make_vector): Fill vectors with the undefined
7229 value, to help make Guile Scheme code more portable to other
7232 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7233 * symbols.h, tags.h: Doc fixes.
7235 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7237 * async.c (scm_take_signal): Doc fixes.
7239 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7241 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7242 want to subtract it from the modulus; we just want to leave it
7245 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7247 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7250 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7252 * throw.c (scm_catch_apply): Finished implementation of
7255 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7257 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7259 (scm_init_filesys): set "i/o-extensions" feature.
7262 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7264 * Makefile.in (root.o): Correct dependencies.
7266 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7268 * Makefile.in: Added dependency entry for root.o.
7270 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7271 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7273 * init.c (scm_start_stack): Set initial root continuation number
7276 * procs.c: New function: scm_thunk_p.
7278 * procs.h: Added declarations of scm_thunk_p.
7280 * root.c: Renamed `call-with-new-root' -->
7281 `call-with-dynamic-root'.
7282 (cwdr): Removed allocation of new root state. This should be done
7283 separately by use of scm_make_root.
7284 (scm_apply_with_dynamic_root): New function: Does what it
7285 sounds like. Needed when spawning threads.
7287 * root.h: Added member last_debug_frame to root state.
7288 Added #include "libguile/debug.h"
7290 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7291 arguments. The motivation is that code in root.c needs catch
7292 functionality, and we want to avoid code duplication.
7293 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7294 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7295 handlers that run without popping the stack into the dynwind
7298 * throw.h: Added prototypes for scm_catch_apply and
7301 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7303 * root.h (scm_root, scm_set_root): Decouple thread support details
7304 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7305 SCM_SET_THREAD_LOCAL_DATA.
7307 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7308 and tortoise scanning loop.
7310 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7312 * Makefile.in: Rebuild dependencies.
7314 * libguile.h: #include "libguile/print.h" before "smob.h", since
7315 the latter uses the print_state structure.
7317 * throw.c (scm_ithrow): Use the correct variable when checking to
7318 see if a given element of scm_dynwinds is a valid catch.
7320 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7321 structure, abort; don't just silently ignore the garbage.
7323 * _scm.h: #include "print.h" here, since it seems to be used just
7325 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7326 strports.c, unif.h: Don't #include "print.h".
7328 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7330 * feature.h (scm_loc_features): Removed external declaration.
7331 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7333 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7335 * feature.c (scm_init_feature): Added threads feature (needs to be
7336 initialized here, since features doesn't exist when
7337 scm_init_threads is called).
7339 * libguile.h: Added #include "libguile/../threads/threads.h".
7340 (This is a kludge to get thread support working. This should be
7343 * configure.in, acconfig.h: Added flags for thread support.
7345 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7348 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7349 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7352 * _scm.h: Added conditional #include "threads.h"
7354 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7355 SCM_THREADS_SWITCHING_CODE.
7357 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7358 allocate the basic dynamic root object.
7359 (scm_boot_guile): Added call to scm_init_root.
7361 * root.c, root.h: Added root smob.
7362 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7363 functions: Implements dynamic roots mostly according to spec in
7364 SCM manual. Main difference is that the second argument is a
7365 throw handler rather than an error "thunk".
7367 * root.h: Added declaration of scm_init_root.
7369 * root.c: Added #include "genio.h", #include "smob.h", #include
7370 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7372 (scm_init_root): Added #include "root.x".
7374 * throw.c: Added #include "stackchk.h"
7375 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7376 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7377 can be used in scm_call_with_new_root; Added reenabling of stack
7378 checking when catching a throw.
7380 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7382 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7384 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7385 element is not found, as per R4RS.
7387 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7389 * list.c: Doc fixes throughout.
7391 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7393 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7394 declare the char * to be const. Avoids a warning in rgx.c.
7396 * ports.h: spelling fix.
7398 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7401 * load.c (scm_sys_try_load_path): throw an error if file not found
7402 (like it says it in NEWS).
7404 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7406 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7407 PROPS slot to '(), not #f; it's an empty alist.
7409 * throw.h, throw.c: Use SCM_P instead of #if hair.
7411 Remove special support for uncaught throws; see throw.c for
7413 * throw.c (uncaught_throw): New function.
7414 (scm_ithrow): Call uncaught_throw if we don't find a throw
7415 target; don't mess with scm_bad_throw_vcell.
7416 (scm_bad_throw_vcell): Variable deleted.
7417 (scm_init_throw): Don't initialize it.
7419 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7422 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7424 * numbers.c (scm_istr2int): If the number is short (as most
7425 numbers are), just call scm_small_istr2int to deal with it.
7426 (scm_small_istr2int): New function, created by un-#ifdefing the
7427 non-bignum version of scm_istr2int and renaming it.
7429 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7431 * load.c (scm_sys_try_load): don't check whether value returned
7432 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7433 Change the Scheme name from %try-load to primitive-load.
7435 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7436 Can avoid passing a message, allowing it to be derived in the
7437 error handler (e.g., if we want to throw to the key both from
7440 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7442 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7443 references now have a new appearance which is more compact and
7444 also gives a clue about what the target of the reference is.
7445 By setting parameters in the print state, more fancy printing can
7446 be achieved. This is used by the (not yet commited) backtrace
7449 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7451 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7454 * print.c: Added #include "struct.h". Removed function
7457 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7458 scm_iprin1. Removed prototype for scm_prlist.
7460 * arbiters.c (prinarb),
7461 async.c (print_async),
7462 debug.c (prindebugobj, prinmemoized),
7463 eval.c (prinprom, prinmacro),
7464 filesys.c (scm_fd_print, scm_dir_print),
7466 mallocs.c (prinmalloc),
7467 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7468 smob.h (scm_smobfuns),
7469 srcprop.c (prinsrcprops),
7471 unif.c, unif.h (scm_raprin1, rapr1),
7472 variable.c (prin_var): Changed argument `int writing' to
7473 `scm_print_state *pstate'.
7475 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7476 that it will be called before scm_init_print.
7478 * print.c (scm_prin1): Print states are now allocated when calling
7479 scm_prin1 and then passed around to all printing functions as an
7480 argument. A cache `print_state_pool' enables reuse of print
7482 (scm_make_print_state): New function.
7483 (scm_iprin1): Adaption to print states.
7484 (scm_iprlist): An initial "hare and tortoise" scan brings down
7485 time complexity to O (depth * N). (Better time complexity will be
7486 achieved when the printing code is completely rewritten.)
7488 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7490 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7491 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7492 it gets done whether or not the cache variable has a value.
7494 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7496 Distinguish #f and ().
7497 * __scm.h: #undef SICP.
7498 * pairs.h (SCM_EOL): Delete this definition, equating it with
7500 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7501 the value it used to have. Doc fixes, too.
7503 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7505 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7506 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7507 Lord's implementation of structs, allowing for tail arrays as
7508 described in the manual. Also fixed some bugs. (Both the interface
7509 and the implementation should be improved.)
7511 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7513 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7514 People who whish to see the source can do `(print-enable 'source)'.
7515 Removed #ifdef DEBUG_EXTENSIONS.
7517 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7519 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7520 integer (assuming for now accepting an integer is a good thing).
7522 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7523 %S will be used instead for write'ing arguments.
7525 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7526 asserts. fix a few other asserts.
7527 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7528 scm_uniform_vector_ref, scm_array_set_x,
7529 scm_dimensions_to_unform_array): change args in
7530 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7531 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7532 scm_substring_fill_x): likewise.
7533 gsubr.c (scm_gsubr_apply): likewise.
7534 eval.c (SCM_APPLY): likewise.
7536 * eval.c (4 places): replace scm_everr with lgh_error or
7539 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7540 scm_memory_error): new procedures.
7541 scm_everr: deleted. can use scm_wta, dropping first two args.
7542 scm_error: convert NULL subr to SCM_BOOL_F.
7544 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7547 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7550 * error.c, error.h: new error keys: scm_arg_type_key,
7551 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7553 scm_wta: reimplement using lgh_error instead of scm_everr.
7555 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7557 * gdbint.c: scm_lread now has one more argument.
7559 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7560 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7561 loading source from non-file ports, which, e. g., happens when
7562 using the Emacs interface).
7564 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7567 * read.c: Added code for recording of positions of source code
7568 expressions; New functions: recsexpr, scm_lreadrecparen;
7569 _scm_make_srcprops --> scm_make_srcprops
7570 (scm_flush_ws): Removed updating of positions counters. This work
7571 is already done by scm_gen_getc
7573 * read.h: Added prototype for scm_lreadrecparen
7575 * print.c: Added #include "alist.h"
7577 * eval.c: Added #include "hash.h"
7579 * eq.c: Added #include "ramap.h"
7581 * options.c: Documentation fixes.
7583 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7584 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7585 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7586 --> scm_make_srcprops
7588 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7589 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7590 function calls in the definition of the whash access macros.
7592 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7594 * init.c (scm_boot_guile): Add level of indirection to
7595 scm_boot_guile_1() to ensure that stack base pointer is properly
7596 initialized. There was no guarantee that variable i was the
7597 highest/lowest variable on stack (i.e. the call frame of
7598 scm_boot_guile was not completely protected from gc).
7600 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7602 * ports.h (scm_port_table): put back file_name, it will be used to
7603 support debugging. Undo related changes in fports.c, ioext.c,
7606 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7608 * ports.h (scm_port_table): remove file_name member for now, it seems
7610 * fports.c (scm_open_file): don't set file_name in PTAB.
7611 (prinfport): don't use file_name in PTAB.
7612 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7613 * ports.c (scm_add_to_port_table): don't intialize file_name.
7614 (scm_port_file_name): remove for now.
7615 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7617 * fports.h (scm_mkfile): prototype deleted.
7618 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7620 * debug.c, unif.c: use scm_out_of_range instead of
7621 wta for range errors (ASSERT still needs work).
7623 * error.c, error.h (scm_out_of_range): new procedure.
7625 * error.c, error.h (scm_out_of_range_key): new key.
7627 * posix.c (scm_sync): #else was missing.
7629 * error.c, error.h: append _key to names scm_num_overflow and
7632 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7633 of consing an empty list.
7634 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7635 of macros, saves code and string space.
7636 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7637 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7638 lower case. Rename scm_syserror_m to scm_syserror_msg.
7639 error.h: prototypes for new procedures.
7641 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7643 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7645 * error.c, error.h: setup scm_num_overflow key.
7647 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7648 Remove definition of SCM_OVSCM_FLOW.
7650 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7652 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7653 explicit message and args.
7655 * error.c, error.h, __scm.h: change system_error_sym to
7658 * error.c (system_error_sym): remove leading %% from the Scheme name
7661 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7663 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7665 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7666 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7667 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7668 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7669 renamed. (These were introduced by unsupervised name
7672 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7674 * print.c: Added code for detection of circular references during
7675 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7676 a hook for printing of closures (accessible via print options).
7677 This leads to a split of calls to scm_iprin1 into two classes:
7678 elementary print operations (e. g. the code which prints a smob)
7679 still use scm_iprin1 while top level calls (like scm_display) use
7680 scm_prin1. scm_prin1 begins by clearing the data structure used
7681 to record reference information.
7683 * print.h: Added declarations of scm_prin1 and scm_prlist.
7685 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7687 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7689 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7691 * error.c (err_head): scm_iprin1 --> scm_prin1
7693 * debug.c: Adjusted header comment.
7697 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7699 * strerror.c: Doc fix.
7701 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7703 * gdbint.c (gdb_read): Now possible to run during GC.
7704 (unmark_port, remark_port): New functions.
7706 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7708 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7709 of allocating a new string object. Also, increase size by
7710 the factor 2 instead of 1.5.
7712 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7714 * __scm.h (SCM_P): Corrected to run under traditional C.
7716 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7719 * async.c: Calls to scm_sysintern corrected.
7721 * async.h (scm_async_clock): Redundant declaration removed.
7723 * continuations.c (scm_dynthrow): Redundant declaration removed.
7725 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7726 Definition typos corrected.
7728 * debug.h: Missing declarations of functions in debug.c added
7731 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7732 Missing declarations to functions in eval.c added.
7734 * filesys.c: Possibly uninitialized variable rv.
7736 * gc.h (scm_object_addr, scm_unhash_name): Missing
7737 declarations of functions defined in gc.c added.
7739 * genio.c: Possible typos str_data -> wstr_data. ???
7741 * genio.c: Possibly unintended shadowing of local variable
7742 `int c' (gotos out of scope of inner `c'). ???
7744 * init.c: Uninitialized `SCM last' may be used.
7746 * ioext.h: (scm_sys_isatty_p): Typo.
7748 * list.h (scm_list_head): Missing prototype for function in
7751 * numbers.c (scm_two_doubles): Changed from extern to static
7752 (is used only within numbers.c).
7754 * numbers.h: Repeated declarations removed.
7756 * ports.h (scm_close_all_ports_except): Declaration for the
7757 function defined in ports.c added.
7759 * posix.h: Missing declarations added.
7761 * procs.h (scm_make_subr_opt): Missing declaration added.
7763 * socket.h (scm_sys_gethost): Missing declaration added.
7765 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7767 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7768 Missing declarations added.
7770 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7772 * struct.c: Uninitialized variable `SCM answer' may be used.
7774 * unif.c (l2ra): Declaration prototype.
7776 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7777 defined in ramap.c).
7779 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7780 Redundant declarations removed (they are in ramap.h).
7782 * variable.h (scm_make_udvariable,
7783 scm_make_undefined_variable): Declaration corrected to
7784 correspond variable.c.
7786 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7787 Missing declarations added.
7789 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7791 * Makefile.in (distclean): Don't forget to delete fd.h.
7793 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7795 * fd.h.in, tags.h: Trivial cleanups.
7797 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7798 marksweep.h just declared functions from gc.c.
7799 * gc.h, libguile.h: Don't #include "marksweep.h".
7800 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7801 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7802 dependencies updated.
7804 * libguile.h: Don't #include "files.h"; it's been deleted.
7806 * files.c (scm_sys_delete_file): Moved to filesys.c.
7807 File is now empty; deleted.
7809 * filesys.c: scm_sys_delete_file is now here. Remove
7810 #if's; they seem to rely on remnants of an old portability
7811 regimen. If the problems come up again, solve them properly,
7812 using autoconf. Specifically: Don't test M_SYSV, and #define
7813 remove to be unlink if it's #defined; don't use remove just
7814 because HAVE_STDC_HEADERS is #defined.
7815 * filesys.h: Add declarations for scm_sys_delete_file.
7816 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7817 files.o, files.h, files.c, and files.x.
7818 * init.c: Don't #include "files.h", and don't call scm_init_files.
7820 Use SCM_P instead of PROTO; the latter intrudes on the user's
7822 * params.h: Deleted; definition of SCM_P moved to...
7823 * __scm.h: ... here, where it replaces PROTO macro.
7824 * libguile.h, smob.h: Don't #include "params.h".
7825 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7826 smob.h: Fix prototypes accordingly.
7827 * Makefile.in: Update dependencies.
7828 (inner_h_files): Remove params.h.
7830 * gc.c: #include "gc.h"; every module should include its header,
7831 to let the compiler cross-check the declarations against the
7834 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7835 simpos.h: #include "libguile/__scm.h".
7837 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7839 * init.c: Don't forget to #include smob.h and init.h.
7840 * Makefile.in: Dependencies updated.
7842 * smob.h: Use PROTO instead of #if __STDC__.
7844 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7846 * __scm.h: Doc fixes.
7848 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7849 <angles>; this allows `make depends' to work properly.
7851 * libguile.h: #include smob.h and pairs.h before the others; they
7852 define typedefs used by other headers.
7854 C files should #include only the header files they need, not
7855 libguile.h (which #includes all the header files); the pointless
7856 recompilation was wasting my time.
7857 * Makefile.in (all .o dependency lists): Regenerated.
7858 * libguile.h: Don't try to get a definition for size_t here...
7859 * __scm.h: Do it here.
7860 * _scm.h: Since this is the internal libguile header, put things
7861 here that all (or a majority) of the libguile files will want.
7862 Don't #include <libguile.h> here; that generates dependencies on
7863 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7864 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7865 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

7900 "weaks.h", "vports.h", "version.h", "vectors.h", "variable.h",
7901 "unif.h", "throw.h", "tag.h", "symbols.h", "struct.h",

7961 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
7962 * weaks.c: Get "weaks.h".
7964 * stackchk.h: #include "libguile/debug.h",
7966 * print.h, read.h: #include "options.h", since everyone who uses
7967 either of these files will need that.
7969 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7970 anyone who uses this file will need them to define the smob
7971 printing functions. Also, get markers.h, since people will need
7972 to #define the mark functions.
7974 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7975 * ports.h: ... to here.
7977 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7978 don't rely on archaic C default type rules.
7980 * fports.h: #include "libguile/ports.h", since you need that in
7981 order to parse this.
7983 * genio.h: #include "libguile/print.h", because you need that to
7984 parse this; don't bother #including "ports.h", since print.h gets
7987 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7989 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7990 this; it's now a reference to an element of *scm_root.
7992 * debug.h: Don't #include "options.h"; the compiler won't be able
7993 to find that once the headers are installed; instead, #include
7994 "libguile/options.h".
7995 * gc.h: Same, with marksweep.h.
7996 * mbstrings.h: Same, with symbols.h.
7997 * scmhob.h: Same, with _scm.h.
7998 * smob.h: Same, with params.h.
8000 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
8001 C files; there's no need for this, and it forces recompilations
8004 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
8006 * error.c (scm_error): declare scm_error_callback.
8008 * error.h: prototype for scm_error_callback.
8010 * __scm.h: define lgh_error.
8011 (SCM_SYSERROR): redefine using lgh_error.
8013 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
8015 * error.c (scm_error): new procedure.
8017 * error.h: prototype for scm_error.
8019 * Makefile.in (install): install scmconfig.h from the current
8020 directory, not $(srcdir).
8022 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8024 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8025 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8026 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
8027 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
8028 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
8029 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8030 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8031 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8032 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8033 vports.h, weaks.h: #include "libguile/__scm.h", not
8034 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
8035 dependencies are within libguile properly.
8037 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8039 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8040 when scmconfig.h doesn't exist.
8042 * load.c (scm_sys_try_load): Correct spelling.
8044 * feature.c (scm_loc_features): Make this static.
8046 * Makefile.in (libpath.h): Omit trailing slash from path. We
8047 shouldn't require it of users, so why put it here?
8049 Move code to initialize and search %load-path from ice-9 to C
8050 code, so we can use the load-path to find the ice-9 boot code;
8051 this makes it easier to run Guile without installing it. See
8052 corresponding changes in guile/Makefile.in.
8053 * feature.c: Move stuff concerned with the load path to load.c.
8054 (scm_compiled_library_path): Deleted.
8055 Don't #include libpath.h here.
8056 * feature.h: Don't mention scm_compiled_library_path.
8057 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8058 <sys/stat.h>, and <unistd.h> (if present).
8059 (R_OK): #define if the system hasn't deigned to.
8060 (scm_loc_load_path): New variable.
8061 (scm_init_load_path, scm_sys_search_load_path,
8062 scm_sys_try_load_path): New functions.
8063 (scm_init_load): Initialize scm_loc_load_path to point to the
8064 value cell of the Scheme %load-path variable.
8065 * load.h: Add declarations for scm_sys_search_load_path,
8066 scm_sys_try_load_path.
8067 * init.c: Call scm_init_load_path.
8068 * Makefile.in (feature.o, load.o): Dependencies updated.
8070 * load.c, load.h: Rewrite using PROTO macro.
8072 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8074 * gc.c (scm_cellp): New function: C predicate to determine if an
8075 SCM value can be regarded as a pointer to a cell on the heap.
8077 * gc.h: Added declaration of scm_cellp.
8079 * gdb_interface.h: New file: The GDB interface header from the GDB
8082 * gdbint.c: New file: GDB interface.
8084 * gdbint.h: New file: GDB interface.
8086 * libguile.h: Added #include <libguile/gdbint.h>.
8088 * init.c (scm_boot_guile): Added scm_init_gdbint.
8090 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8091 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8092 found if object files and source are kept separate).
8094 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8096 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8098 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8100 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8101 TK_SRC_DIR; they're not relevant any more.
8103 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8104 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8106 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8108 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8109 search path, so we can find the <libguile/MUMBLE.h> headers.
8111 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8113 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8114 implicit in the .c.o rule.
8115 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8118 Put the library path in a header file, instead of passing it on
8119 the command line in every compilation.
8120 * Makefile.in (libpath.h): New target.
8121 (feature.o): Depend on libpath.h.
8122 (clean): Delete libpath.h.
8123 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8124 * feature.c: ... #include "libpath.h" here.
8125 * .cvsignore: Ignore libpath.h.
8127 Don't install the unwashed masses of Guile header files in the
8128 main #include path; put most of them in a subdirectory called
8129 'libguile'. This avoids naming conflicts between Guile header
8130 files and system header files (of which there were a few).
8131 * Makefile.in (pkgincludedir): Deleted.
8132 (innerincludedir): New variable; this and $(includedir) are enough.
8133 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8134 (installed_h_files): Divide this up. Now this variable lists
8135 those header files which should go into $(includedir) (i.e. appear
8136 directly in the #include path), and ...
8137 (inner_h_files): ... this new variable says which files appear in
8138 a subdirectory, and are referred to as <libguile/mumble.h>.
8139 (h_files): List them both.
8140 (install): Create innerincludedir, not pkgincludedir. Put
8141 the installed_h_files and inner_h_files in their proper places.
8142 (uninstall): Corresponding changes.
8143 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8144 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8145 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8146 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8147 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8148 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8149 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8150 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8151 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8152 vports.h, weaks.h: Find __scm.h in its new location.
8153 * __scm.h: Find scmconfig.h and tags.h in their new locations
8154 (they're both "inner" files).
8156 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8158 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8160 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8162 * posix.c: Doc fixes.
8164 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8166 * socket.c: Don't include a prototype for inet_aton; just use a
8167 K&R style declaration, to avoid warnings but minimize the chance
8168 of conflicts with the system.
8170 On NextStep, <utime.h> doesn't define struct utime, unless we
8171 #define _POSIX_SOURCE before #including it.
8172 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8173 * acconfig.h: New comment text for above CPP symbol.
8174 * configure.in: Call it.
8175 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8177 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8179 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8180 testing for __EMX__.
8182 * posix.c: #include <libc.h>, if it exists.
8184 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8185 don't even know if the latter exists.
8187 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8188 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8189 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8191 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8193 (scm_init_posix): Use them when initializing the Scheme constants
8196 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8198 * Makefile.in (libdir, includedir, bindir): Use the
8199 autoconf-supplied values, instead of deriving them ourselves.
8200 (pkgincludedir, datadir, pkgdatadir): New variables.
8201 (install, uninstall): Put the header files in a special
8202 subdirectory, not in the main search path.
8204 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8205 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8207 * Makefile.in (IMPLPATH): Deleted; never used.
8209 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8210 on the Tcl/Tk source any more.
8211 (INCLUDE_CFLAGS): Remove references to the above.
8213 * Makefile.in (version.o): Corrected dependencies.
8215 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8217 * libguile.h: #include "version.h"
8219 * init.c (scm_boot_guile): Call scm_init_version.
8220 * gscm.c (gscm_run_scm): Call scm_init_version.
8222 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8223 GUILE_VERSION): AC_DEFINE these.
8224 (acconfig.h): #undef the above symbols.
8226 * Makefile.in (libobjs): Add version.o.
8227 (installed_h_files): Add version.h.
8228 (c_files): Add version.c.
8229 (gen_c_files): Add version.x.
8230 (version.o): New rule.
8231 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,

8241 weaks.o): Add version.h to dependency lists.
8242 (markers.o): Remove duplicate rule.
8244 * version.h: New file.
8246 * version.c: New file.

8250 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8251 array; use it appropriately. Since GCC is quite happy to
8252 subscript functions, it never warned us about this; we should use
8253 -Wpointer-arith in the future. I guess we never tested
8256 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8258 * socket.c: Doc and copyright fixes.
8260 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8262 * debug.c: Fixed and improved gdb support.
8264 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8266 * socket.c: Added declaration of inet_aton to avoid compiler
8267 warning. (Hope this solution is correct.)
8269 * stime.c: Added declaration of ftime. (This is missing in
8272 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8274 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8276 * Makefile.in (c_files): add strerror.c.
8278 * strerror.c: new file from Emacs' sysdep.c.
8279 maybe configure should also check for sys_errlist.
8281 * configure.in (AC_REPLACE_FUNCS): add strerror.
8283 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8285 * debug.c (scm_init_debug): Added initialization for
8286 scm_evaluator_traps.
8288 * debug.h, debug.c: Various name changes.
8289 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8290 "debug-options-interface". See commentary in options.c.
8292 * options.h, options.c: Options now have documentation strings.
8293 Also added a long explanatory commentary.
8295 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8298 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8299 last_debug_info_frame is now updated in all cases.
8301 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8304 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8306 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8307 Added option STACK_CHECKING.
8309 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8311 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8313 * __scm.h: Removed symbols for debugging support.
8315 * acconfig.h: Added symbols for debugging support.
8317 * configure.in: Added user option for debugging support.
8318 --enable-debug will include the debugging code into libguile.a.
8320 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8321 scm_relocate_chunk_to_heap.
8323 * debug.c: New file: low-level debugging support. It also
8324 includes support for debugging with gdb. (The extensions to gdb
8325 are written by Per Bothner at Cygnus.)
8327 * debug.h: New file: low-level debugging support.
8329 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8330 argument pairs. Extensive modifications to the debugging
8331 evaluator. Added "SECTION:" commentaries to clarify what happens
8332 when, during double compilation. Renamed EVALIMP --> EVALIM.
8333 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8334 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8335 the beginning of the file. New procedure: scm_unmemocopy.
8336 Added some global state variables needed by the debugging
8337 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8338 check_entry, check_apply, check_exit, debug_options and
8339 evaluator_traps. New acro: undefine.
8341 * eval.h: Renamed EVAL --> XEVAL.
8343 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8344 --> scm_make_weak_key_hash_table.
8346 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8347 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8349 * libguile.h: Conditionally include debug.h
8351 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8352 scm_object_properties shouldn't return handle. `handle' now gets
8353 initialized in scm_set_object_properties_x. scm_object_properties
8354 doesn't any longer create an entry in scm_object_whash.
8356 * options.c: New file: handling of run time options.
8358 * options.h: New file: handling of run time options.
8360 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
8362 * print.c: New procedure: scm_print_options
8364 * print.h: Defines for print options.
8366 * read.c: New procedure: scm_read_options
8368 * read.h: Defines for reader options.
8370 * root.h: Added scm_source_whash among scm_sys_protects.
8372 * srcprop.c: New file: source properties.
8374 * srcprop.h: New file: source properties.
8376 * throw.c (jbsmob): Jump buffers are now correctly allocated.
8377 (Bug found by A. Green.)
8379 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8381 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8383 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8385 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8387 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8388 and should be called by the final client.
8390 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8392 * gc.h: Use the PROTO macro when declaring functions.
8393 * gc.c: Use the PROTO macro when declaring static functions.
8394 Remove the CPP hair around function definitions.
8396 * gc.c (scm_init_storage): Initialize scm_asyncs.
8398 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8399 preprocessor symbol; "__scm.h" is where it might get #defined.
8400 * __scm.h: Similar: #include <scmconfig.h> before testing
8403 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8405 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8407 * init.c (scm_boot_guile): Add init_func argument; call
8408 (*init_func) instead of calling scm_appinit; it's ucky to
8409 hard-code names for the user's procedures.
8410 * init.h (scm_boot_guile): Adjust declaration.
8412 * __scm.h (PROTO): New macro, for declaring functions with
8415 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8416 eliminate all the __STDC__ conditionals.
8417 (scm_boot_guile): Add declaration.
8418 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8419 Remove __STDC__ conditionals around function definitions; the
8420 declarations in init.h will provide the same information, more
8423 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8424 complain about it in the error message; the error message is
8425 adequate without that note, and there's nothing the user can do
8428 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8430 * Makefile.in (ancillary): Drop def.sed.
8432 * posix.c (scm_init_posix): Use numeric values, rather than
8433 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8434 F_OK. The symbols aren't available on some systems, and I'm
8435 pretty sure their values are fixed by common widespread practice.
8436 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8438 More functions unavailable on some systems.
8439 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8440 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8442 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8443 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8444 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8445 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8446 stub that signals an error as the #else.
8448 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8450 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8452 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8454 * unif.c: include ramap.h.
8456 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8458 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8460 * ports.c: include sys/ioctl.h.
8462 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8464 * configure.in: check for sys/ioctl.h.
8466 * ports.c: include <malloc.h> not "malloc.h".
8468 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8470 * fports.c: remove ttyname and tmpnam declarations.
8472 * posix.c: fewer ttyname declarations.
8474 * fports.c: include <string.h> not "string.h".
8476 * init.c, ioext.c: include string.h and unistd.h.
8478 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8480 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8481 genio.c, simpos.c, vports.c: include string.h.
8483 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8485 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8487 (scm_addr_buffer_size): change type from scm_sizet to int.
8488 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8489 from scm_sizet to int.
8491 * error.c: include unistd.h.
8493 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8496 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8498 * __scm.hd, def.sed: deleted.
8500 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8502 Changes for NeXT, suggested by Robert Brown.
8503 * configure.in: Call AC_TYPE_MODE_T.
8504 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8505 NeXT. Put header file list in alphabetical order.
8506 * configure, scmconfig.h.in: Regenerated.
8507 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8509 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8512 * acconfig.h: New file, providing documentation for the CPP
8513 symbols defined in configure.in
8514 * acconfig-1.5.h: Removed; superceded by the above.
8516 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8518 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8520 * fports.c (scm_open_file): don't return #f, throw error.
8522 * ioext.c (fileno): renamed from %fileno.
8523 (soft-fileno): deleted.
8525 * ports.c (scm_port_revealed): don't need to check for -1 from
8527 (scm_set_port_revealed_x): return unspecified, not #f.
8529 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8531 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8533 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8535 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8537 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8539 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8540 This is necessary on Ultrix, and doesn't hurt portability.
8542 * Makefile.in (dist-dir): New target, implementing a new dist system.
8543 (installed_h_files): Put in alphabetical order.
8544 Remove duplicate entries for markers.h and unif.h.
8545 (c_files): Remove duplicate entries for markers.c.
8546 (ancillary): Renamed from anillery; all uses changed. Remove
8547 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8548 Remove all the ../doc/* files; doc/Makefile.in handles that.
8550 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8552 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8553 every if must have an else, or else the whole command has a
8554 non-zero exit code whenever the if's condition is false.
8556 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8558 * posix.c: include string.h.
8560 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8562 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8565 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8566 Remove leading % from scheme names.
8567 Do not return error values, call SCM_SYSERROR or similar.
8569 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8571 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8573 * struct.c (scm_init_struct): new file.
8575 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8577 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8578 (scm_list_head): added list-head for rapidly chopping argument
8579 lists off of longer lists (and similar).
8581 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
8583 * objprop.c (scm_object_property): assq the cdr of the whash
8584 handle for obj, not the handle itself.
8586 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8588 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8589 weak hash tables last of all marking to avoid an obscure gc bug.
8590 WARNING: circular lists stored in a weak hash table will hose us.
8592 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8594 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8595 new functions similar to scm_substring_move_left_x and
8596 scm_substring_move_right_x.
8598 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8600 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8603 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8605 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8607 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8609 * strports.c (scm_strprint_obj): convenience function. C for
8610 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8612 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8613 removed to a separate library
8615 * init.c (scm_boot_guile): copied from guile-tcl.c.
8616 Initialization specific to tcl interpreters removed.
8618 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8620 * ports.c (scm_ports_prehistory): size malloced here doesn't
8621 matter so long as it is non-0 (got rid of "* 4").
8623 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8625 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8626 since its definition was bogus).
8628 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8630 * mallocs.[ch]: back again (for rx at least).
8632 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8634 * ports.c: removed functions relating to the mapping between ports
8635 and descriptors. (That stuff is unix-specific and should be collected
8636 in a separate library).
8638 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8639 (Tom Mckay@avanticorp.com)
8641 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8643 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8644 handled correctly (SCM_FREEP was applied to them) -- test for
8645 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
8646 being overwritten with #f. (brown@grettir.bibliotech.com)
8648 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
8650 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

8660 * list.c (scm_last_pair): map '()=>'()
8662 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>

8665 Generalized assoc and hash-table functions.
8666 Factored pairs.c into multiple files.
8668 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
8670 * gscm.c (gscm_run_scm): got rid of objprop.
8672 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
8674 * genio.c (scm_getc):
8675 NOTE: fgetc may not be interruptable.
8677 * procprop.c (scm_stand_in_scm_proc):
8678 NOTE: don't use a alist here.
8679 (scm_set_procedure_properties_x): fix type checking throughout this file.
8681 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
8683 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
8684 after freeing part of the port table.
8686 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
8688 * strports.c (scm_mkstrport):
8689 * vports.c (scm_make_soft_port): allocate a port table entry
8690 (possibly triggering gc) before setting the tag of the corresponding
8693 * pairs.c (scm_delq_x): never throw an error.
8695 * vectors.c (scm_make_vector): made the default vector fill argument
8696 into '() (much more useful than the previous value, "#unspecified")
8698 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
8700 * ports.c (scm_add_to_port_table): Added fields
8701 to port table entries: file_name, line_num, col.
8702 Update these in open_file, gen_getc and gen_ungetc.
8703 Added procedures to access those fields.
8705 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
8707 * procs.c (scm_make_subr_opt): new entry point for making
8710 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
8712 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
8714 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
8716 * numbers.c (scm_exact_p): This function no longer
8717 implements "integer?".
8719 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
8721 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
8722 (scm_gc_stats): return an assoc of useful data. Replaces "room"
8723 and the stats reporting formerlly built into repl.
8725 * repl.[ch]: removed.
8726 GC statistics keeping moved to gc.c.
8727 Other statistics keeping can be done from Scheme.
8728 REPLS are now written in Scheme.
8730 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
8732 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
8733 conservatively marked objects).
8735 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
8737 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
8739 * feature.c (scm_compiled_library_path): moved here from repl.c.
8740 This file is for stuff relating specifically to Scheme libraries
8743 * eval.c (scm_m_define): don't give warning about redefinition, don't
8746 NOTE: this should throw a resumable exception with parameters --
8747 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
8749 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
8751 * error.c: scm_warn eliminated.
8753 * read.c (scm_lreadr): extra right paren gets an error, not a warning.
8755 * repl.c, marksweep.c, gc.c (various):
8756 lose exit_report, growth_mon.
8758 * gscm.c: got rid of verbosity functions.
8760 Tue Feb 20 00:19:10 1996 Tom Lord <lord@beehive>
8762 * throw.c (scm_ithrow): guard against the bad-throw hook changing
8763 between the call to procedurep and use.
8765 * error.c (scm_everr):
8767 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
8770 * strports.c: don't reveal the port's string to the caller
8771 because it changes size.
8773 (stputc stwrite): check/change the strings length with interrupts
8776 * objprop.c (scm_set_object_property_x &c): use the generic
8777 hashing functions and be threadsafe.
8779 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
8780 (per suggestion jaffer@gnu.ai.mit.edu).
8782 * mbstrings.c (scm_multi_byte_string): guard against argument list
8785 * strings.c (scm_make_string): loop cleanup
8787 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
8790 * weaks.c (scm_weak_vector): guard against argument list
8793 * variable.c (scm_builtin_variable): check for/make a built-in
8796 * vectors.c (scm_vector): while filling the new array,

8813 initialization to fix a race condition.
8815 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

8839 set the multi_byte flag correctly in symbols. This is wrong.
8840 intern_obbary_soft and msymbolize should take an extra parameter.
8841 Also, weird multibyte symbols don't print correctly.
8842 The weird symbol syntax is also a bit bogus (emacs doesn't quite
