1 1999-09-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3 * backtrace.c: #include <unistd.h> if present.
5 1999-09-14 Jim Blandy <jimb@savonarola.red-bean.com>
7 * Makefile.am (.c.x): Don't create a subshell just to delete the
8 .x file and return false.
9 * Makefile.in: Regenerated.
11 1999-09-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
13 * feature.c (scm_create_hook): New function. Replaces
14 scm_make_named_hook which is now deprecated.
15 (scm_make_hook_with_name): New primitive.
16 (print_hook): Hooks now print in a fancy way.
18 1999-09-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
20 * __scm.h, backtrace.c, backtrace.h, debug.c, debug.h, dynl-dld.c,
21 dynwind.c, dynwind.h, eval.h, evalext.c, evalext.h, feature.c,
22 feature.h, hashtab.c, hashtab.h, objects.c, objects.h, print.c,
23 procs.c, procs.h, smob.c, smob.h, srcprop.c, strorder.c, struct.c,
24 struct.h: Updated copyright notices.
26 * srcprop.c (scm_source_property): Bugfix: Use SCM_NECONSP instead
27 of SCM_NCONSP. (Thanks to Greg Badros.)
29 * gsubr.c (scm_make_gsubr): Use scm_make_subr_opt for creation of
32 * eval.c, debug.h (SCM_BACKTRACE_WIDTH): New debug option: width.
34 * backtrace.c: Keep backtraces within specified width by
35 adaptively adjusting fancy printing parameters and cut output if
37 (scm_display_application): Check args.
39 1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
41 Change the name of the objects returned by OPENDIR from
42 "directory" to "directory stream". A predicate named "directory?"
44 * filesys.c (scm_directory_stream_p): Renamed from scm_directory_p.
45 At the Scheme level, "directory?" -> "directory-stream?".
46 (scm_dir_print): Use the phrase "directory stream" in printed form.
47 * filesys.h (scm_directory_stream_p): Prototype renamed
50 * Makefile.am (CLEANFILES): Remove versiondat.h; that should only
51 be removed by `make distclean', since it's generated by configure.
52 * Makefile.in: Regenerated.
53 (Thanks to Robert Bihlmeyer.)
55 * strop.c (scm_substring_move_x): Signal an error if start1
56 doesn't come before end1. (Thanks to Karoly Lorentey).
58 * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
59 calling SCM_NIMP. (Thanks to Karoly Lorentey).
61 * version.c (scm_libguile_config_stamp): Deleted. See
62 corresponding change to ../ice-9/boot-9.scm.
63 * versiondat.h.in: Remove definition for GUILE_STAMP.
64 * version.h: Delete prototype.
65 * Makefile.in: Regenerated.
67 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
69 * filesys.c (scm_directory_p): new procedure "directory?" Returns
70 a boolean indicating whether its argument is a directory
71 port as returned by opendir (thanks to Dirk Herrmann for the
74 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
76 * backtrace.c (display_frame_expr): Don't print a newline.
77 (display_frame): Print the newline here instead.
78 (display_backtrace_body): Don't print "Backtrace:".
79 (scm_backtrace): Print "Backtrace:" here instead.
81 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
83 * procs.c (scm_setter): Signal WTA if handed an entity or operator
86 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
87 primitives. (Thanks to Greg Badros);
88 (scm_hook_to_list): New primitive; Hooks are now smobs.
90 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
92 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
93 of #f for the 10th vector element to avoid an exception
94 seen by Bernard Urban.
95 (scm_mktime): unneeded ASSERT removed.
97 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
99 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
102 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
104 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
106 * numbers.c: Converted comparison operations to dispatch on
107 generic if args don't match.
109 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
111 1999-09-06 James Blandy <jimb@mule.m17n.org>
113 * guile-snarf.c: Deleted. Snarfing should respect CPP
114 conditionals, so it needs to actually run CPP. Bleah.
116 1999-09-05 James Blandy <jimb@mule.m17n.org>
118 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
119 * guile-snarf.in: Be sure to exit with an error if CPP does.
120 * Makefile.am (.c.x): Delete the .x file and exit with an error
121 status if guile-snarf exits with an error status.
122 * Makefile.in: Regenerated.
124 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
125 scm_makekey, which doesn't exist any more. Guess nobody's using
128 * guile-snarf.c: New implementation of guile-snarf, meant to be
129 more robust than the shell script. I think it's complete, but I
130 haven't tested it at all, and I haven't changed the build process
131 to actually use it. We should compare its output against that of
132 the existing shell script, for all source files.
134 * guile-snarf.c (parse_args): Abort if we haven't handled some
137 1999-09-03 James Blandy <jimb@mule.m17n.org>
139 * load.c (scm_search_path): If the filename has any extension at
140 all, ignore the entire list of extensions. Also, don't check whether
141 the file is accessible. If the file exists, accessible or not, we
142 should return it. Inaccessible files should cause an error later.
143 (Thanks to Keisuke Nishida for the suggestions.)
145 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
147 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
148 atexit not available. (sunos4.1.4 needs it.)
150 1999-09-01 James Blandy <jimb@mule.m17n.org>
152 I take it all back --- bcopy does handle overlapping source and
153 destination areas correctly. At least on every system I could
154 find. But it is better to use AC_REPLACE_FUNCS than to introduce
155 new CPP conditionals.
156 * memmove.c: New file, implementing memmove in terms of bcopy.
157 * scmconfig.h.in: Regenerated.
159 Allocators should use the `void *' type for generic pointers.
160 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
161 argument and return types.
162 * gc.h: Corresponding changes to prototypes.
165 1999-08-31 James Blandy <jimb@mule.m17n.org>
167 * numbers.c (scm_init_numbers): Claim to support the `complex'
168 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
170 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
171 find (ice-9 boot-9) when Guile was compiled in a separate
172 directory from the source. (Thanks to Rodney Brown.)
173 * Makefile.in: Regenerated.
175 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
176 table lengths by the size of a single element when growing the
177 table. (Thanks to Bill Schottstaedt.)
179 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
181 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
182 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
183 since that cuts down the time for type dispatch by 50%.
185 1999-08-30 James Blandy <jimb@mule.m17n.org>
187 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
188 not a correct substitute for memmove, because it doesn't handle
189 overlapping source and destination areas on many platforms.
190 Overlaps are the primary reason to use memmove in the first place.
191 * ports.c (scm_ungetc): Same.
192 * strop.c (scm_substring_move_x): Same.
194 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
196 * gc.c (scm_init_storage): Skip registration of cleanup on systems
197 which lack atexit. (Is it important that cleanup is made
198 properly? Maybe we should replace all `exit' with `scm_exit' and
201 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
202 scm_struct_free_standard, scm_struct_free_entity): Declared to
203 return scm_sizet instead of size_t.
205 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
206 there on sunos4.1.4.)
208 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
210 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
211 Account for the case when second argument is unbound.
213 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
214 (Thanks to Karoly Lorentey.)
216 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
217 isn't present. (Thanks to Suzuki Toshiya.)
219 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
222 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
225 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
226 Bernard Urban and Ian Grant.)
228 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
229 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
230 change in the representation of entities and operators.)
232 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
234 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
235 don't allocate zero bytes (thanks to Bill Schottstaedt).
237 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
239 * procs.c (scm_setter): Converted to use generic dispatch.
241 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
244 * load.c (scm_search_path): Don't try extensions which already are
245 present at the end of the filename.
246 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
248 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
250 Cleanup and simplification of generic method dispatch.
251 Also, the quadruple representation of entity and operator
252 procedures has been replaced with single.
254 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
256 * print.c (scm_isymnames): Removed #@hash-dispatch.
258 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
259 from eval.c; Support 0 arity methods.
260 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
261 (scm_apply_generic_env): Removed.
262 Replaced slots proc0-3 with procedure.
264 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
265 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
266 SCM_OPERATOR_PROCEDURE.
267 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
268 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
270 * struct.c, struct.h: Replace 4 procedure slots with one.
271 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
273 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
276 * eval.c (scm_sym_args): Removed.
277 (SCM_CEVAL): Simplified entity application.
278 Moved dispatch code to objects.c.
280 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
282 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
284 * sort.c (closureless): Use scm_eval_body.
286 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
287 with a symbol as last form was first called normally and then via
288 `map' or some other mechanism using primitive apply, an ILOC was
291 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
293 This change extends the representation of primitive procedures
294 with more data fields, e.g. a place for documentation and true
295 procedure properties.
297 * procs.c, procs.h (scm_subr_entry): New type: Stores data
298 associated with subrs.
299 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
300 SCM_SUBR_DOC): New macros.
301 (scm_subr_table): New variable.
302 (scm_mark_subr_table): New function.
304 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
306 * gc.c (scm_gc_mark): Don't mark subr names here.
307 (scm_igc): Call scm_mark_subr_table.
310 This change implements a scheme for letting a generic work as a
311 shadow for a primitive procedure. If the primitive procedure
312 can't dispatch on its arguments, control is left over to the
313 generic. Normal wrong type arg errors will be generated until the
314 user has hung the first method on the primitive.
316 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
318 * procs.c, procs.h (scm_subr_p): New function (used internally).
320 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
322 * objects.c, objects.h (scm_primitive_generic): New class.
324 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
326 * print.c (scm_iprin1): Print primitive-generics.
328 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
329 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
331 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
332 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
333 primitives). NOTE: This means that it is now *required* to use
334 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
335 obscured representation that will be removed in the future anyway,
336 so backward compatibility is no problem here).
338 * numbers.c: Converted most numeric primitives (all but bit
339 comparison operations and bit operations) to dispatch on generic
343 Better support for applying generic functions.
345 * eval.c, eval.h (scm_eval_body): New function.
347 * objects.c (scm_call_generic_0, scm_call_generic_1,
348 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
352 Optimization of the generic function dispatch mechanism.
354 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
355 called scm_memoize_method instead of doing a second lookup.
357 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
362 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
363 scm_sysintern so that the binding connected with the subr name
364 isn't cleared when we give set = 0.
367 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
369 More transparent handling of ports with print states.
371 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
372 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
373 instead of a pair of a port and a print state. We'll need to cons
374 once extra in scm_printer_apply but the type system will be
375 cleaner, it will mix better with GOOPS, and, it will be even more
376 transparent to the user.
378 * print.c (scm_get_print_state): New procedure: Given an output
379 port, return the print state associated to it in the current print
380 chain, if one exists;
381 (scm_port_with_print_state): New procedure: Associate a
382 print-state with a port.
383 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
384 (scm_printer_apply): Wrap port and pstate as a smob;
385 (print_state_printer): Removed.
387 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
389 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
392 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
393 testing (otherwise the port-print-state trick won't be transparent
394 to the user; one example where this caused problems was in the
395 (ice-9 format) module).
397 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
399 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
400 SCM_UNSPECIFIED instead of the set value.
402 1999-08-20 James Blandy <jimb@mule.m17n.org>
404 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
406 * ports.h (enum scm_port_rw_active): New enum, containing
407 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
408 zero). The debugger knows about enums, but doesn't know about
410 (typedef scm_port): Declare rw_active member to be an enum
412 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
414 * ports.c (scm_add_to_port_table): Same.
415 * strports.c (st_flush, st_end_input): Same.
417 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
418 scm_must_realloc, and scm_done_malloc as appropriate.
420 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
422 * sort.c (quicksort): Added condition to protect the algorithm
423 from crashing the interpreter if the less predicate is buggy.
425 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
427 * fports.c (fport_write): fix line-buffering mode again.
428 (scm_open_file): recognise 'l' for line-buffering.
429 (scm_setvbuf): recognise _IOLBF for line-buffering.
431 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
433 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
436 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
439 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
441 * fports.c (fport_write): use memcpy instead of strncpy, in case
442 the data contains NUL.
444 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
446 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
448 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
449 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
450 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
451 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
452 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
453 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
454 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
455 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
456 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
457 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
458 scm_sym_ as prefix for symbols.
460 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
462 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
463 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
464 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
465 scm_sym_atcall_cc): Made global.
467 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
469 * eval.c (scm_sym_args): Made global.
471 * objects.c (scm_set_object_procedure_x): Disallow setting of
472 procedures for pure generic functions.
474 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
476 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
477 Scheme name from lseek to seek, but lseek was added recently so
478 it shouldn't be a big problem.
479 * ports.c, gdbint.c, ioext.c: changed callers.
481 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
483 * fports.c (fport_input_waiting): if select is used, return 1
484 instead of whatever FD_ISSET expands to. maybe it will be useful
485 to interpret the value from the input_waiting ptob procedure as a
486 lower bound on the number of bytes available.
488 * Mikael asked for a few names to be changed...
490 * ports.c (scm_make_port_type): take the write procedure as the
491 second argument instead of the flush procedure.
492 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
493 fflush -> flush, read_flush -> end_input, fclose -> close,
494 fill_buffer -> fill_input, ftruncate -> truncate,
495 input_waiting_p -> input_waiting.
497 * ports.c (end_input_void_port): was read_flush_void_port.
498 (scm_set_port_end_input): was scm_set_port_flush_input.
499 (scm_set_port_flush): was scm_set_port_write.
500 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
501 (scm_end_input): was scm_read_flush.
502 (scm_fill_input): was scm_fill_buffer.
503 (scm_flush): was scm_fflush.
504 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
505 (fport_end_input): was local_read_flush.
506 (fport_flush): was local_fflush.
507 (fport_close): was local_fclose.
508 (fport_truncate): was local_ftruncate.
509 (fport_seek): was local_seek.
510 (fport_free): was local_free.
511 (fport_fill_input): was fport_fill_buffer.
512 * strports.c (st_end_input): was st_read_flush.
513 (st_truncate): was st_ftruncate.
514 * vports.c: (sf_flush): was sfflush.
515 (sf_close): was sfclose.
516 (sf_fill_input): was sf_fill_buffer.
518 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
521 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
523 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
524 forms now contain the expressions to be dispatched upon instead of
525 depending on a surrounding lambda or let; Generic function
526 dispatch has been optimized; `apply' on a generic function now
527 works a little bit strangely. It uses a trick so that the type
528 dispatch code in SCM_CEVAL can be reused.
530 * objects.h, objects.c (scm_apply_generic_env): Added (used by
532 (scm_operator_p): Added.
533 (scm_sym_atdispatch): Added.

542 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
544 * feature.c, feature.h (scm_c_run_hook): Added.
546 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
547 cdrxnoap and loopnoap instead of begin and loop.
549 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
551 * ports.c (scm_putc, scm_puts),
552 * unif.c (scm_uniform_array_write): use scm_lfwrite.

555 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
557 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
558 SCM_IM_HASH_DISPATCH.
560 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
561 (scm_si_redfined, scm_si_hashsets): Moved.
563 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
564 flag which combines type and status info so that the class
565 redefinition protocol has zero cost during normal execution.
567 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
569 * ports.h (scm_ptob_descriptor): include a write procedure again.
570 it's more efficient for unbuffered fports (e.g., sockets.)
572 * ports.c (scm_puts): use ptob->write.
573 * vports.c (scm_make_sfptob): set write proc in ptob.
574 * strports.c (scm_make_stptob): set write proc in ptob.
575 * ports.c (write_void_port): new procedure.
576 * vports.c (sf_write): new procedure.

578 * strports.c (st_write): new procedure.
579 * fports.c (fport_write): new procedure.
580 (scm_make_fptob): set write in ptob to fport_write.
581 * ports.h: prototype for scm_set_port_write.
582 * ports.c (scm_make_port_type): initialise ptob write procedure.
583 (scm_set_port_write): new proc.
585 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
587 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
588 until we've verified that it is actually a port. (Thanks to
591 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
593 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
594 code, particularly an unnecessary test (len != size, where len ==
595 size). (Was this leftovers from debugging code, or have I missed
598 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
599 size. (Thanks to James Dean Palmer.)
601 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
602 (Thanks to Lorentey Karoly.)
604 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
606 * eval.c (scm_m_expand_body): Use scm_cons_source.
608 * struct.c (scm_print_struct): Use vtable name.
610 * print.c (scm_init_print): Set name of print state type.
612 * stacks.c (scm_init_stacks): Set name of stack type.
614 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
616 * eval.c (SCM_CEVAL): Removed old implementation of internal
619 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
621 * debug.c, debug.h (scm_reverse_lookup): Added.
622 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
623 internal procedure definitions; Don't use scm_i_inner_name.
625 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
628 * eval.h: Added prototypes for multi language support functions.
630 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
631 improper lists in the low-level representation, since that will
632 cause a begin to be prepended at macro expansion.
634 * eval.c (scm_cons_source): Version of cons which copies source
635 properties from an existing cell.
636 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
638 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
639 procedure source before calling scm_unmemocopy instead of faking
642 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
644 Ported `internal defines' fix from SCM. Original ChangeLog entry:
646 1998-07-09 Radey Shouman <radey@colorage.com>
648 * eval.c (ceval_1): Modifications to allow rewriting of interal
649 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
650 body of which it is the CAR is macro expanded by m_expand_body,
651 which rewrites internal DEFINE.
653 (m_expand_body): Added.
655 (m_macroexp1): Added argument to control error checking:
656 m_expand_body may speculatively expand forms in the wrong
657 environments. Made argument number checks conditional on
660 (m_body): Added, error checks bodies and inserts the ISYM tokens.
662 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
665 (m_cond): (m_case): (m_quote): Modified to avoid destructively
666 changing their argument forms. Since m_expand_body
667 speculatively macro expands forms the process must be
670 (m_ident_eqp): Fixed to use proper environment.
672 (renamed_ident): Added DEFER_INTS_EGC.
674 Added prototypes for static functions.
680 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
681 is false, do not produce an error for unbound variables, return a
682 pointer to cell_undef instead.
684 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
688 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
689 destructively changing their argument forms. Since m_expand_body
690 speculatively macro expands forms the process must be reversible.
692 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
693 SCM_IM_LET introduced by named lets.
695 (scm_m_letstar): Use scm_m_body instead of bodycheck.
697 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
698 scm_letrec. scm_letrec1 does not check for a null binding and
699 takes an additional argument to specify the ISYM of the body. Use
700 scm_m_body instead of bodycheck.
702 (scm_m_let): Use scm_m_body instead of bodycheck.
704 (scm_m_expand_body, scm_macroexp): New.
706 (unmemocopy): Account for ISYMs introduced by scm_m_body.
708 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
709 check=1. Throw error for internal defined that have not been
710 rewritten by scm_m_expand_body.
712 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
713 Removed prototype for SCM_APPLY.
715 * tags.h: Added extern declaration of scm_isymnames.
717 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
719 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
721 * lang.c: New file: Beginning of multi-language support.
723 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
725 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
726 (scm_dynamic_wind): Added argument checking for the after guard so
727 that we don't add garbage on the dynwind chain.
728 (scm_swap_bindings): Added.
730 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
731 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
732 (scm_isymnames): New isyms for multi-language support.
734 * eval.c (scm_nil, scm_t): New symbols.
735 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
736 forms for multi-language support.
738 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
740 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
742 Renamed functions in the random function library interface
743 from scm_i_XXX --> scm_c_XXX.
745 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
747 * ports.c (scm_putc): fix line-buffering.
749 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
751 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
752 scm_set_ptob_XXX --> scm_set_port_XXX.
754 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
756 * ports.c, ports.h (scm_make_port_type): New interface for
757 creation of port types (replaces scm_newptob). Just as for the
758 smobs, we need to separate the internal representation of smob
759 types from the interface, so that we easily can add new fields and
760 rearrange things without caring about backward compatibility.
761 This change was forced by the need in GOOPS to create classes
762 representing port types.
763 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
764 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
765 scm_set_ptob_seek, scm_set_ptob_truncate,
766 scm_set_ptob_input_waiting_p): New setters.
767 (scm_newptob): Rewritten to use scm_make_port_type. For backward
769 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
770 (scm_prinport): Removed.
771 (scm_port_print): Added.
772 (scm_print_port_mode): Added.
773 (void_port_ptob, print_void_port, close_void_port, noop0):
774 Removed. Removed #include "genio.h" Added #include "objects.h",
777 * fports.c (prinfport): Moved code from ports.c.
779 (scm_fptob): Removed. Instead use new interface.
780 (scm_make_fptob): Added. (Need to create basic ports in a
781 specific order in ports.c.)
783 * strports.c (scm_stptob, prinstpt, noop0): Removed
784 (scm_make_stptob): Added.
786 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
787 (scm_make_sfport): Added.
789 * filesys.c (scm_dir_print): Don't use the port printing code.
790 Instead provide specific directory printer.
792 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
794 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
797 * smob.c (scm_smob_print): Handle non-existing type name nicely.
798 Removed #include "genio.h"
800 * objects.c (scm_make_port_classes): New function ptr.
802 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
804 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
806 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
807 allow the 1st argument to be a fdes or filename as well as a
808 port (as in the filesys.c version).
810 * filesys.c (scm_truncate_file): removed.
812 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
814 * readline.c, readline.h: Removed.
816 * objects.c, objects.h (scm_port_class): Added.
817 (scm_class_of): Look up port class in scm_port_class.
818 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
819 SCM_INOUT_PCLASS_INDEX): Added.
822 * Makefile.am: Removed genio.c, genio.x.
826 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
828 * init.c: Make sure that scm_post_boot_init_modules is called only
829 once. (Important when using a dumped image.; Thanks to Bernard
832 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
834 * guardians.c (scm_guardian_zombify): Separate scanning for
835 zombies from marking the pairs of the free list.
837 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
838 use the macros. (Thanks to Michael Livshin.)
840 * eval.c (scm_m_lambda): Let bodycheck check the body of the
841 lambda. Let your sins be purified by the blood of the lambda.
842 (Thanks to Eric Hanchrow.)
844 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
845 (Thanks to Valdis Kletnieks.)
847 Fixes for EMX from Mikael Ståldal.
849 * filesys.c: #include <io.h>, if we have it.
850 * scmconfig.h.in: Regenerated.
852 * stime.c (ftime): Delete declaration for this function --- let
853 the system supply it.
855 Cleanups from John Bley.
857 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
859 * gsubr.c: Don't include "gsubr.h" twice.
861 Cleanups for compilation on Irix 6, from David Kaelbling.
863 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
864 regex_t pointer. This is what the callers have, mostly.
865 (scm_regexp_exec): Don't forget to pass the `rx' argument to
866 scm_regexp_error_msg.
868 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
869 int. That way, if we get a warning on this line, it's more likely
870 that we're really missing bits we care about.
872 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
875 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
876 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
877 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
878 cast at all is more appropriate in every case. At the moment, we
879 assume everywhere that SCM is an integral type anyway.
881 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
883 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
884 read_pos after scm_fill_buffer.
886 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
889 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
890 fports.c (fport_fill_buffer): implement the interface change.
892 * ports.c (scm_fill_buffer): interface change: no longer increments
893 read_pos past the character that's returned. it seems clearer to
894 leave it to the caller to decide what to do (thanks Jim).
896 * vports.c (sf_fill_buffer): put the read char into the buffer
897 as well as returning it.
899 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

904 * strports.c (scm_strprint_obj): simplify. start with initial
906 (st_seek): don't allow string to be extended if seeking past
907 the end of a read-only port.
909 1999-07-12 Gary Houston <ghouston@easynet.co.uk>

913 * ports.c (scm_ftruncate): throw error if offset works out negative.
915 * strports.c (st_flush): increase string size in blocks of
916 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
917 it's greater and reset read_buf_size.
918 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
919 to be maintained for output ports too (it holds the written
920 part of the string, while write_buf may have unwritten buffer
922 (st_truncate): rewritten.
923 (top of file): added a few notes.
925 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
927 Patch from Greg Badros:
928 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
929 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
930 (function pointer) argument to scm_make_gsubr and scm_make_subr
931 calls. This avoids warnings in C++ programs using guile-snarf.
933 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
935 * strports.c (st_grow_port): set pt->read_pos. set
936 pt->read_buf_size one less than pt->write_buf_size if there's
937 an unwritten char at the end of the string. similarly for
939 (st_resize_port): renamed from st_grow_port.
940 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
941 seek from read_end instead of write_end for SEEK_END.
942 (st_ftruncate): calculate current length using readbuf, not write
944 (scm_strport_to_string): use read_buf_size for length.

949 * strports.c (scm_strport_to_string): new procedure.
950 (scm_call_with_output_string, scm_strprint_obj): use
951 scm_strport_to_string.
952 used SCM_INUM0 instead of SCM_MAKINUM (0) in a few places.
954 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
956 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)

960 * smob.c: added scm_make_smob_type_mfpe (), scm_set_smob_mfpe ();
961 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
962 and "bigneg" smob types.
964 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
965 SCM_RETURN_NEWSMOB macro. Added protos for new functions in

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

1053 * dynl-dl.c (sysdep_dynl_link): Added parenthesis around the
1054 trinary conditional in order for the flag computation to be
1057 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1059 * struct.c, struct.h:
1061 In order to support different kinds of deallocation, a destructor
1062 slot has been added to struct vtables. This allows for structs
1063 containing pointers to other memory blocks.
1065 (scm_struct_i_free): New hidden struct slot. Holds destructor for
1066 instances to this vtable.
1067 (scm_struct_free_0): New destructor: Doesn't deallocate data.

1134 1999-06-19 Jim Blandy <jimb@savonarola.red-bean.com>
1136 Patch from Greg Harvey:
1137 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1138 around the condition of an `if', `while', etc., even if the
1139 condition is a macro invocation that expands to something
1140 surrounded by parens. It's more readable.
1142 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1143 proper lists, and of the appropriate lengths.
1144 (check_map_args): New function. (Thanks to Greg Harvey for the
1147 1999-06-19 Michael Livshin <mike@olan.com>

1168 * gc.h (scm_mallocated): Fix declaration.
1169 (Thanks to Greg Harvey.)

1175 * stime.c (bdtime2c): Initialize lt->gmtoff and lt->tm_zone from
1176 sbd_time. (Thanks to Eric Hanchrow.)
1178 Fix from Ken Raeburn <raeburn@raeburn.org>:
1179 * weaks.c (scm_make_weak_vector): Add another extra slot before
1180 vector contents, to be used only during garbage collection.
1181 * weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
1182 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
1184 (scm_weak_size, scm_n_weak): Deleted.
1185 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
1186 vectors without allocating new storage during GC, using
1187 scm_weak_vectors as the head of the chain.
1188 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1189 instead of stepping through an array.
1190 (scm_gc_sweep): Update offset used to find start of weak vector to
1192 (scm_init_storage): Set scm_weak_vectors to EOL.
1194 Fix from Ken Raeburn <raeburn@raeburn.org>:
1195 * gc.c (already_in_gc): New variable.
1196 (scm_igc): Set and clear already_in_gc; abort if it's set at
1199 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
1201 Fix from Gary Houston:
1202 * fports.c (local_seek): Signal an error if the seek fails.
1203 * ports.c (scm_lseek): Don't check return value of port's seek
1204 function; it's its job to signal an error if there's a problem.
1206 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
1208 * strports.c (scm_call_with_output_string): Don't include the

1211 * ioext.c (scm_read_line): Switch to reading properly.
1213 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
1214 scmsigs.c, strports.c, vports.c: Install the sources which
1215 actually correspond to the changes described below. I got the
1216 ChangeLog entries and the patch from two different places...
1218 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1220 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1221 it shows up as terrible performance, as we GC constantly.
1223 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1224 newline. A bit faster, and definitely hairier.
1225 (scm_read_line): Count newlines here instead.
1227 * strings.c (scm_take_str): New function.
1228 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1229 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
1230 scm_take_str, to avoid copying the string.
1232 Add some simple-minded support for line buffered ports.
1233 * ports.h (SCM_BUFLINE): New flag for ports.
1234 * init.c (scm_init_standard_ports): Request line-buffering on
1235 the standard output port.
1236 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1238 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1239 and there's a newline to be written, flush the port.
1241 Gary Houston's open-buffer port patches:
1243 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1245 * ports.c: (scm_lseek): clear buffers even if just reading current
1248 * fports.c (local_fclose): call local_fflush unconditionally.

1251 1999-04-25 Gary Houston <ghouston@easynet.co.uk>
1253 * ports.h (scm_port): make read_pos a pointer to const.
1254 strports.c: take care of rw_active and rw_randow.
1255 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
1256 strports.c (scm_mkstrport): check that pos is reasonable.
1257 ioext.c (scm_ftell, scm_fseek): use lseek.
1258 (SCM_CLEAR_BUFFERS): macro deleted.
1259 ioext.c (redirect_port: use ptob fflush, read_flush.
1260 ports.h (scm_ptobfuns): add ftruncate.
1261 ports.c (scm_newptob): set ftruncate.
1263 ports.c (scm_ftruncate): new procedure.
1264 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
1265 strports.c (st_seek, st_grow_port): new procs.
1266 fports.h (scm_port): change size types from int to off_t.
1267 ports.c (scm_init_ports): initialise the seek symbols here
1268 instead of in ioext.c.
1269 strports.c (scm_call_with_output_string): start with an empty
1270 string, so seek and ftruncate can be used.
1272 gdbint.c: adjust string port usage.
1274 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1276 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1277 equivalent to fflush for the read buffer.
1278 * ports.c (scm_newptob): set read_flush.
1279 ports.c (void_port_ptob): set read_flush.
1280 fports.c (local_read_flush): new proc. add to ptob.
1281 strport.c (st_read_flush): likewise.
1282 vport.c (sf_read_flush): likewise.
1283 fports.h (struct scm_fport): remove random member. there's nothing
1284 left but fdes. leaving it as a struct to allow for future changes.
1285 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1286 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1287 ptob proc if the read buffer is filled.
1289 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1291 * ports.h (scm_port): add a rw_random member and replace
1292 reading and writing members with rw_active member.
1293 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1295 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1297 * ports.h (struct scm_port_table): add writing and reading members
1298 to replace write_needs_seek: it isn't good enough for non-fports.
1299 ports.c, ioext.c, fports.c: corresponding changes.
1300 (struct scm_port_table): give it a typedef and rename to scm_port.
1301 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1302 corresponding changes.
1304 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
1306 * ports.c (scm_newptob): bugfix: set seek member.
1307 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
1308 and generalised to all port types.
1310 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
1312 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1313 signals (it was only being done for handlers installed from Scheme).
1314 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1315 waiting for input caused an EINTR error from read.
1317 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1319 * ports.h (struct scm_port_table): make all the char members
1320 unsigned, so they convert to int without becoming negative if large.
1322 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1324 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1325 with threads enabled. rename this procedure to
1326 fport_wait_for_input and take a port instead of a fdes.
1327 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1329 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1330 get readline support working again: use fdopen to get FILE objects.
1332 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1334 * gc.c (scm_init_storage): install an atexit proc to flush the
1336 (cleanup): the new proc. it sets a global variable which can be
1337 checked by the ptob flush procs to avoid trying to throw
1338 exceptions during exit. not very pleasant but it seems more reliable.
1339 * fports.c (local_fflush): check terminating variable and if set
1340 don't throw exception.
1341 * CHECKME: that the atexit proc is installed if unexec used.
1343 * throw.c (scm_handle_by_message): don't flush all ports here.
1344 it still causes bus errors.
1346 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1347 and move to ioext.c.
1349 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1351 * ports.c (scm_char_ready_p): check the port buffer and call the
1352 ptob entry if needed.
1354 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1355 ptob initialisers. use it in char-ready
1357 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1359 * vports.c (sfflush): modified to write a char (since softports
1360 currently use shortbuf.)
1362 * fports.c (scm_standard_stream_to_port): moved to init.c and
1365 * init.c (scm_init_standard_ports): make stdout and stderr
1366 unbuffered if connected to a terminal. with stdio they
1367 were line-buffered by default.
1369 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1372 * ports.h (scm_ptobfuns): change fflush return to void.
1373 change flush proc definitions.
1375 * strports.c (scm_call_with_output_string): get size from
1376 buffer instead of port stream.
1377 (st_flush): new proc.
1379 * ports.h (struct scm_port_table): added write_end member,
1380 as an optimisation. set it where write_buf_size is set.
1382 * ports.h (struct scm_port_table): change stream from void *
1383 back to SCM. SCM presumably must be large enough to hold a
1384 pointer (and probably vice versa but who knows.)
1385 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1387 (scm_puts): rewritten
1388 * fports.c (local_ffwrite, local_fputs): removed.
1389 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)
1390 * vports.c (sfputc, sfputs, sfwrite) likewise.
1391 * ports.c (write_void_port, puts_void_port): removed.
1392 (putc_void_port, getc_void_port, fgets_void_port): likewise.
1394 * ports.c (scm_lfwrite): rewritten using fport.c version.
1396 * fports.c (local_fputc): deleted.
1398 * ports.c (scm_add_to_port_table): initialise write_needs_seek.
1400 * ports.h (scm_ptobfuns): add seek function pointer.
1401 * fports.c: set it to local_seek, new procedure.
1404 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1405 use ptob for seek. take ptob instead of fport arg.
1407 * ports.h (struct scm_port_table): new member write_needs_seek,
1408 replaces reading member in fport struct.
1410 * vports.c (sfgetc): store the getted char into the buffer.
1411 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1412 the Scheme interface is still a procedure that gets a char.
1413 (scm_make_soft_port): set up the port buffer (shortbuf).
1415 * fports.c (local_fgetc, local_fgets): deleted.
1416 * strports.c (stgetc): likewise.
1417 * ports.c: scm_generic_fgets: likewise.
1419 * ports.h (scm_ptobfuns): add fill_buffer.
1420 * ports.c (scm_newptob): assign it.
1421 * strports.c (scm_mkstrport): set up the buffer.
1422 put just the string into the stream, not cons (pos stream).
1423 (stfill_buffer): new proc.
1425 * ports.h: fport buffer moved into port table: to be
1426 used for all port types.

1435 scm_getpeername, scm_recv, scm_send, scm_recvfrom,
1437 use SCM_FPORT_FDES. use SCM_OPFPORTP not SCM_FPORTP.
1439 * posix.c (scm_getgroups): use SCM_ALLOW/DEFER_INTS.
1440 (scm_ttyname): use SCM_FPORT_FDES.

1471 * gdbint.c: likewise.
1472 * ports.h (SCM_SSTREAM): new macro.
1474 * fports.c (scm_input_waiting_p): use scm_return_first, since port

1497 ports.c fports.c ioext.c posix.c socket.c net_db.c filesys.c:
1498 removed all uses of SCM_DEFER/ALLOW ints for now. they were mainly
1499 just protecting errno. some may need to be put back.
1501 * scmsigs.c (take_signal): save and restore errno while this
1504 *fports.c (print_pipe_port, local_pclose, scm_pipob): deleted.

1619 1999-05-09 Jim Blandy <jimb@savonarola.red-bean.com>
1621 * strop.c (scm_string_capitalize_x): Use the SCM object `s' in

1625 * strop.c (scm_substring_move_x): New function, which can handle
1626 arbitrary overlapping substrings.

1701 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1703 * numbers.c (isfinite): Define this macro if not defined: Return a
1704 non-zero value if X is finite. (From ISO C 9x standard.)

1757 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1759 Most of this batch of changes is about how to deal with extended
1760 types when an object system is loaded into Guile. A nice object
1761 system is capable of representing Guile's types as class objects.
1763 For example, we want a regular expression to be of class <regex>.
1764 But regular expressions are smobs which aren't under direct
1765 control of the object system, so there has to be some mechanism
1766 which informs the object system that a new class should be created
1767 which can represent the smob type. I call this a "wrapper class".
1769 * objects.c: #include "smob.h";
1770 (scm_class_keyword): Removed. (Class is automatically created by
1772 (scm_smob_class): Array of smob classes indexed by smobnum.
1773 (scm_make_extended_class): "Plugin" function pointer for creation
1774 of wrapper classes for smob and struct types.
1775 (scm_class_of): Handle compiled closures. (Currently regarded as
1777 Use scm_smob_class to handle smob types;
1778 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1779 through scm_smob_class;
1782 * smob.c (scm_newsmob): Also create a wrapper class if
1783 scm_smob_class has been initialized.
1785 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1786 type code and smobnum.
1788 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1789 (scm_struct_table): Weak key table with auxilliary information for
1790 struct types. Currently used for names and wrapper classes.
1791 (scm_struct_ihashq): Hash function for structs.
1792 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1793 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1794 for accessing names of vtables. The record implementation in
1795 boot-9.scm currently uses the setter to record the name of record
1796 types. When the object system is initialized, it can use this
1797 information to create wrapper classes with suitable names.
1798 (scm_init_struct): Allocate scm_struct_table.
1799 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1800 (struct tags are a finite resource and we might want to restrict
1801 the use of tags to vtables only. E.g., Goops only uses tags for
1803 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1805 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1808 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1809 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1810 Used for access of struct table entries.
1812 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1813 (scm_hash_fold): New procedure. Used to process all entries in a
1814 hash table (in no particular order).
1816 Argh! For the umpteenth time I got compilation errors because of
1817 the "intuitive" name `kw'. This has to have an end:
1819 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1820 "kw" --> "keywords" everywhere.
1821 (I doubt that this will cause big compatibility problems since the
1822 application interface is unaffected.)
1824 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1826 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1828 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1829 column inums to native form.
1831 Improvement of backtraces: Introduces a new stack narrowing
1832 specifier, #t, for the inner cut. (See further in the comments in
1833 stacks.c:narrow_stack ().)
1835 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
1836 (Used to flag certain system procedures which shouldn't turn up in
1839 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1840 modules which aren't "user" modules and the code of which
1841 shouldn't turn up in backtraces.)

1844 Extract the lookup closure from an environment.
1845 (scm_system_module_env_p): New function: Return non-#f if MODULE
1848 * stacks.c: #include "eval.h"; #include "procprop.h";

1851 * debug.c (scm_procedure_name): Use name property in the default
1854 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1856 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1858 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1859 procedure throughout.
1861 * print.c (scm_iprin1): Removed extraneous space when printing
1862 procedure-with-setters.
1864 Entity and operator setter slots were introduced as a complement
1865 to the <procedure-with-setter> type in order to support entities
1866 and operators with setters in a reasonable and efficient way.
1867 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1870 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1883 directly through the instance.
1885 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1887 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1888 scm_struct_i_flags instead of scm_vtable_index_layout!
1890 * list.c (scm_list_star): New procedure.
1892 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1973 SYMB now point to const.
1975 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1977 * print.c (scm_iprin1): Use scm_procedure_name instead of
1978 scm_procedure_property for compiled closures.
1980 * tags.h (scm_tc7_pws): New procedure type. Four representations
1981 for procedure-with-setters were considered before selecting this
1984 1. A closure where the CODE and ENV slots are used to represent
1985 the getter and a new SETTER slot is used for the setter. The
1986 original getter is stored as a `getter' procedure property. For
1987 closure getters, the CODE and ENV slots contains a copy of the
1988 getter's CODE and ENV slots. For subr getters, the CODE contains
1991 2. A compiled closure with a call to the getter in the cclo
1992 procedure. The getter and setter are stored in slots 1 and 2.
1994 3. An entity (i.e. a struct with an associated procedure) with a
1995 call to the getter in the entity procedure and the setter stored
1996 in slot 0. The original getter is stored in slot 1.
1998 4. A new primitive procedure type supported in the evaluator. The
1999 getter and setter are stored in a GETTER and SETTER slot. A call
2000 to this procedure type results in a retrieval of the getter and a
2001 jump back to the correct eval dispatcher.
2003 Representation 4 was selected because of efficiency and
2006 Rep 1 has the advantage that there is zero penalty for closure
2007 getters, but primitive getters will get considerable overhead
2008 because the procedure-with-getter will be a closure which calls
2011 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
2012 <procedure-with-setter>, but together with rep 2 it suffers from a
2013 three level dispatch for non-GOOPS getters:
2015 cclo/struct --> dispatch proc --> getter
2017 This is because the dispatch procedure must take an extra initial
2018 argument (cclo for rep 2, struct for rep 3).
2020 Rep 4 has the single disadvantage that it uses up one tc7 type
2021 code, but the plan for uniform vectors will very likely free tc7
2022 codes, so this is probably no big problem. Also note that the
2023 GETTER and SETTER slots can live directly on the heap, using the
2024 new four-word cells.
2026 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

2077 1999-01-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2079 * random.c, random.h (scm_i_make_rstate): New function: Makes
2080 scm_rstate from seed.
2081 (scm_copy_random_state, scm_seed_to_random_state): New functions.
2082 (scm_make_random_state): Removed.
2084 * random.c (scm_make_random_state): Use scm_i_make_rstate().
2086 1999-01-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2088 * random.c: Bugfix: Retrieve and store most significant 32 bits in
2089 different order if the machine is bigendian.
2090 (scm_init_random): Added safety check for bignum digit size.
2092 1999-01-11 Roland Orre <mdj@mdj.nada.kth.se>
2094 * sort.c (scm_merge, scm_merge_list_x): Bugfix: Place elements
2095 from first arg before equal elements in second arg in result.
2096 (scm_merge_list_step): Bugfix: Don't presume that arguments in a C
2097 function call are executed in a well defined order.
2099 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2101 * alloca.c (alloca): Cast value returned by malloc. (Thanks to
2104 1999-01-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2106 * random.c: Removed alloca includes.
2108 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2110 * Makefile.in: This changed, for some reason I don't really
2111 understand, when I ran automake in the top level directory. This
2112 may be contamination by Cygnus internal releases. If you re-run
2113 automake and this change gets reverted, don't worry about it.
2115 1999-01-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2117 * sort.c, sort.h: New files: Implement slib's and scsh's sort

2127 * numbers.c: Formatted according to Guile conventions;
2128 Renamed s_bignum --> scm_s_bignum.
2130 * random.c, random.h: New files: Random number support.
2131 Interface same as slib's.
2133 * Makefile.am: Added random.c, random.h, random.x.
2135 * init.c: #include "random.h";
2136 (scm_boot_guile_1): Call scm_init_random ().
2138 1998-12-23 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2140 * Makefile.am: New files: guardians.c, guardians.x, guardians.h
2142 * guardians.c, guardians.h (scm_make_guardian,
2143 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
2144 scm_get_one_zombie, scm_init_guardian): This is an implementation
2145 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
2146 David Eby (1993) "Guardians in a Generation-Based Garbage
2147 Collector" ACM SIGPLAN Conference on Programming Language Design
2148 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
2149 /pub/scheme-repository/doc/pubs/guardians.ps.gz
2150 Author: Michael N. Livshin.
2152 * gc.h (SCM_MARKEDP, SCM_NMARKEDP): New macros.
2154 * gc.c (scm_igc): Call scm_guardian_gc_init and
2155 scm_guardian_zombify.
2157 * init.c (scm_boot_guile_1): Call scm_init_guardian.
2159 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2161 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
2164 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2166 Move the procedure slots of entities to invisible slots (so that
2167 we can have operator class objects which themselves are entities).
2168 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
2169 SCM_STRUCTF_ENTITY): New constants.
2171 * struct.c (scm_make_struct): Allocate "invisible" room for
2172 procedures if SCM_STRUCTF_ENTITY is set in vtable.
2174 * gc.c (scm_gc_mark): Mark entity procedures.
2176 * struct.c, struct.h (scm_alloc_struct): Renamed from alloc_struct
2178 (scm_struct_init): Renamed from init_struct and made global.

2181 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
2182 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
2184 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
2186 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
2187 of syntactic forms, similar to SCM_PROC.
2188 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
2189 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
2190 for the name symbols when needed.
2192 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
2194 * Makefile.in: Regenerated.
2196 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
2198 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
2199 take the address of _into; it might be a register. Just have
2200 scm_debug_newcell return the new cell.
2201 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2202 taking the address of a place to store it as an argument.
2203 * gc.h (scm_debug_newcell): Change declaration.
2204 (Thanks to Greg Harvey.)
2206 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2208 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
2209 Replaces old names serial-array-copy! and serial-array-map!.
2211 * evalext.c (map-in-order): New name. Replaces serial-map.
2213 1998-12-05 Jim Blandy <jimb@totoro.red-bean.com>
2215 * smob.c (freeprint): New function.
2216 (freecell): Use it to print freed objects, for slightly easier
2219 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2221 * backtrace.c (display_frame): Made more robust. Doesn't throw an
2222 error if no source properties can be found for a frame. (Thanks
2223 to Christian Lynbech.)
2225 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2227 * objects.h: Removed slots direct_supers and direct_slots from the
2228 definitions of the rudimentary classes described by objects.h.
2230 * objects.c, objects.h (scm_entity_p): New procedure. Together
2231 with the predicates scm_procedure_p and scm_struct_p, this
2232 predicate makes it possible to differ between structs, entities
2235 * modules.c, modules.h (scm_resolve_module): New function.
2237 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2239 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2240 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2243 * objects.c (scm_entity_p): New procedure.
2245 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
2246 for asubrs, rpsubrs, lsubrs and lsubr_2s.
2248 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2250 * procprop.h (scm_i_procedure_arity): Added declaration.
2252 * procprop.c (scm_i_procedure_arity): Made global; New code to
2253 handle operators and entities.
2254 (scm_procedure_property): No need to call scm_procedure_p since
2255 scm_i_procedure_arity now does all necessary type checking.
2256 Added #include "objects.h".
2258 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2259 s_add_hook_x --> s_remove_hook_x.
2260 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
2261 Added #include "procprop.h"
2263 * feature.c, feature.h (scm_reset_hook_x): New procedure.
2264 (scm_make_hook): Optional argument defines number of arguments to
2266 (scm_make_named_hook): Take number of args as second arg.
2267 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2268 boot-9.scm for a while); First arg is the hook. The rest are
2269 arguments passed on to the hook procedures.
2271 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2273 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2274 scm_logbit_p): Do the computation in ulongs. This is not as nice
2275 as doing it in bignums, but at least it's good enough for
2276 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2278 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2279 subexpressions. (Thanks to Charbel Jacquin.)
2281 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2283 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2284 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2285 (scm_make_named_hook): New function.
2287 * feature.c: Added #include "eval.h".
2289 * modules.c (scm_make_module): Beautify the module.
2291 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2293 * modules.c, modules.h: New files: C interface to modules. (This
2294 is necessary in order to interface the object system to Guile
2295 properly. The guts of these modules will be replaced by the new
2296 module system in the future.)
2298 * init.c: Added #include "modules.h"
2299 (scm_boot_guile_1): Call scm_init_modules.
2300 (invoke_main_func): Call scm_post_boot_init_modules.
2302 * Makefile.am: Added modules.c, modules.x, modules.h.
2304 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2306 * procs.c: #include "objects.h"
2307 (scm_procedure_p): Return #t also on structs which are operators.
2309 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2310 <operator-metaclass> and <entity-class> to <standard-class>,
2311 <operator-class> and <entity> in order to conform with STKlos
2314 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2315 which isn't an operator.
2316 (SCM_APPLY): Ditto, but jump to badproc.
2318 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2320 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2321 Previously, structs implanted in code were interpreted as forms
2322 the operator of which was a gloc. We solve this by checking for
2323 the zero in the emulated vcell in the struct vtable. Since
2324 implanted structs always will look like forms with a gloc
2325 operator, execution will only be slowed down by maximally one
2326 extra test-and-branch per application.
2328 * evalext.c (scm_definedp): Removed check for isyms; Added a
2329 second optional argument: It is now possible to supply an
2330 evaluation environment in which to look for the symbol.
2332 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2334 * readline.c (scm_init_readline): Set
2335 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2337 * coop.c (coop_condition_variable_wait): Removed
2338 (coop_condition_variable_wait_mutex): Folded logic of
2339 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2340 prevent condvar signal lossage. Previously, another thread could
2341 start to run after unlocking the mutex but before putting the
2342 current thread on the wait queue. If that thread then would
2343 signal the first, the signal would be lost. (Thanks to Christian
2346 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2348 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2351 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2353 * objects.c (scm_i_make_class_object): Renamed from
2354 make_class_object; exported; error checking moved to
2355 scm_make_class_object and scm_make_subclass_object.
2356 (scm_make_class_object, scm_make_subclass_object): Use
2357 scm_i_make_class_object.
2358 (scm_make_subclass_object): Let the subclass have same metaclass
2361 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2363 * debug.c (scm_debug_options): Bugfix: Set the value of
2364 scm_stack_checking_enabled_p after setting debug options;
2365 #include "stackchk.h". (Thanks to Richard Polton.)
2367 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2369 * unif.c (scm_array_contents): removed unnecessary test for 0
2372 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2374 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2375 Replaced by macro `collect' in boot-9.scm.
2377 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2379 * eval.c (scm_copy_tree): Copy source properties if existent.
2381 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2382 don't, we may end up passing memoized source to a transformer.)
2384 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2386 * stack.c (get_applybody): Help function which lookups the first
2387 body form of the apply closure.
2388 (read_frames): Prevent the source of the first form of the apply
2389 closure from being recorded. This would only be confusing.
2391 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2392 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2394 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2396 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2398 (read_frames): Use SCM_MACROEXPP.
2400 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2402 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2403 don't contain interesting information since all arguments are
2404 present in the frame which applies the compiled closure anyway.);
2405 Skip the transformer application frames.
2407 * print.c (scm_iprin1): Print gsubrs as primitives.
2409 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2411 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2413 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2414 that we can identify these in a backtrace. (This change doesn't
2415 introduce any significant speed penalty.)
2417 * eval.c: Added note about `serial-map' using scm_map.
2419 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2420 readline options. They should reside in their own options array.
2422 * readline.c, readline.h (scm_readline_options,
2423 scm_readline_opts): Moved readline options here.
2425 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2427 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2428 SCM_ROCHARS instead of SCM_CHARS.
2430 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2431 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2433 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2435 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2436 This is quite important since the latter clears the
2437 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2438 every single character read...
2440 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2442 * print.c (scm_iprin1): Removed suspect looking (and indeed
2443 malevolent) semicolon after test for user supplied closure print
2444 procedure. (Thanks to Telford Tendys.)
2446 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2447 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2448 starting to search the list. Removed call to sloppy_mem_check.
2450 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2451 procedures: Same as scm_delq_x et al, but delete maximally one
2454 * options.c (scm_options, scm_init_options): GC-protect option
2455 values of type SCM. (Thanks to Telford Tendys.)
2457 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2459 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2460 make sure that there always is a "real" scm_lookupcar.
2462 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2464 * read.c, read.h (scm_read_opts): New read options
2465 "history-length" and "history-file".
2466 (scm_read_options): Stifle history to history length.
2468 * readline.c (scm_read_history, scm_write_history): New procedures.
2470 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2472 * eval.h (scm_macro_eval_x): Removed declaration.
2474 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2475 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2476 Renamed and made global.
2478 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2479 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2481 * evalext.c, evalext.h: New files. Contain non-R5RS things
2482 having to do with evaluation.
2484 * evalext.c (scm_serial_map): New procedure: Version of `map'
2485 which guarantees that the procedure is applied to the lists in
2487 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2488 returns a list of the results of the body forms instead of the
2489 result of the last body form.
2490 (scm_definedp, scm_m_undefine): Moved from eval.c
2492 * evalext.h (scm_m_sequence_to_list): Added declaration.
2494 * macros.c, macros.h: New files.
2495 (scm_procedure_to_syntax, scm_procedure_to_macro,
2496 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2497 scm_macro_name, scm_macro_transformer): Moved from eval.c
2498 (scm_make_synt): Moved from eval.c
2500 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2502 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2505 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2507 * debug.c, print.c: Added #include "macros.h".
2509 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2511 This change adds the ability to use `unread-char' multiple times
2512 without interspersed reads and adds the new procedure
2513 `unread-string'. The change is optimized for the common case of
2514 unreading a single character. This is also the reason behind the
2515 choice to store characters in the port itself: in most cases no
2516 extra malloc is required.
2518 The amount of code in some macros in ports.h has been increased to
2519 the extent that they would fit better as C functions, but, since
2520 this code belongs to the port representation, such functions
2521 should be placed in ports.c which would cause calls back and forth
2522 between ports.c and genio.c. That is not good for performance.
2523 Also, keeping them as macros allows the compiler to do some
2524 optimizations which are needed to make the current interface
2525 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2527 One benchmark (Guile startup time) indicates an increase of
2528 loading speed of 1%. Another (reading (using `read') boot-9.scm
2529 10 times) shows no change in performance.
2531 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2532 made to find a beautiful solution.)
2534 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2535 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2536 character. (SCM_CLRDY clears all.)
2537 (SCM_N_READY_CHARS): New macro: Returns number of unread
2538 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2539 (struct scm_port_table): New fields: `entry' contains port table
2540 index, `cp' points to last unread char, `cbuf' is the buffer for
2541 unread chars, `cbufend' points after end of the character buffer.
2543 * ports.h, ports.c (scm_unread_string): New procedure.
2544 (scm_grow_port_cbuf): New function.
2546 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2548 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2549 to read unread characters. Use SCM_TRY_CLRDY instead of
2552 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2554 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2556 * genio.c, genio.h (scm_ungets): New function.
2558 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2561 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2563 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2564 declarations. (Thanks to Russ McManus.)
2566 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2568 * numbers.c (num2long): As a software archeologist, I'm proud of
2569 this finding! :) Preliminary dating suggests an almost 4 year old
2570 remnant from the SCM ancestor. The sample has been removed from
2571 the finding site and is now safely stored in the repository.
2573 * numbers.h: Removed prototype for num2long.
2575 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2577 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2578 array as second arg.
2579 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2580 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2581 * gh.h: Updated and added prototypes.
2583 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2585 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2587 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2589 * guile-snarf.in: Never generate an empty file. (Thanks to
2592 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2593 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2594 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2595 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2596 gh_new_procedure5_0): Specify argument types, to appease C++
2597 compilers. (Thanks to Brad Bowman.)
2599 Bug reports from Russ McManus:
2600 * guile-snarf.in: If the CPP environment variable is set, use that
2601 as the C preprocessor, instead of the preprocessor autoconf
2603 * snarf.h (SCM_PROC): Cast the function pointer passed to
2604 scm_make_gsubr, to satisfy C++.
2606 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2607 Use the handler passed, instead of ignoring it and using
2608 gh_standard_handler. (Thanks to Etienne Bernard.)
2610 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2612 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2615 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

2632 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2635 * script.c (scm_compile_shell_switches): Define
2636 use-emacs-interface in the root module, so the repl code can see
2637 it. See today's change to top-repl in ice-9/boot-9.scm.
2639 * filesys.c (set_element, get_element): Make sure that `element'
2640 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2641 Boekemeier and Jorgen "forcer" Schaefer.)
2643 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2645 * chars.c (scm_charnames): In ASCII character name table, make
2646 newlines print as #\newline by default, not #\nl.
2648 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2649 alphabetical order. Oh thrills. But it helps me know how far
2650 along in the compilation I am.
2651 * Makefile.in: Regenerated.
2653 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2655 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2656 #bytes(...) to #y(...), and syntax for short vectors from
2657 #short(...) to #h(...). This may seem nutty, but, like the other
2658 uniform vectors, byte vectors and short vectors want to have the
2659 same print and read syntax (and, more basic, want to have read
2660 syntax!). Changing the read syntax to use multiple characters
2661 after the hash sign breaks with the conventions used in R5RS and
2662 the conventions used for the other uniform vectors. It also
2663 introduces complexity in the current reader, both on the C and
2664 Scheme levels. (The Right solution is probably to change the
2665 syntax and prototypes for uniform vectors entirely.)
2667 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2669 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2670 (Thanks to Jorgen "forcer" Schaefer.)
2671 * ports.h (SCM_NOFTELL): New flag.
2672 * fports.c (local_fgets): If it's set, use the generic fgets.
2673 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2675 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2677 * script.c (scm_compile_shell_switches): Add handling of -q switch
2678 (inhibit loading of user init file).
2679 (scm_shell_usage): Add usage text for -q switch.
2680 (scm_compile_shell_switches): Always load user init file first if
2681 it is loaded at all.
2683 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2685 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2686 and is now broken under NetBSD. I can't fathom what it's trying
2687 to do, so I've replaced it with something that I do understand,
2688 which seems to work, and which isn't broken on NetBSD. "Progress?
2689 You Decide." (Thanks to Perry Metzger.)
2691 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2692 signed/unsigned comparison.
2694 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2696 Warning fixes from Greg Harvey:
2697 * unif.c (scm_array_set_x): initializer for pos
2698 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2699 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2700 initializers for field_type, since EGCS so desparately wants to
2702 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2703 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2704 when GUILE_DEBUG is defined.
2705 * dynwind.h (scm_wind_chain): Same.
2706 * ports.h (scm_pt_size, scm_pt_member): Same.
2707 * print.h (scm_current_pstate): Same.
2708 * procs.h (scm_make_cclo): Same.
2710 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2712 Handle short and long long uniform arrays properly. (Thanks to
2714 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2715 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2716 scm_tc7_llvect (long long vectors).
2718 Change the way libguile and boot-9.scm are timestamped, to try to
2719 get rid of these spurious mismatch warnings. Now both
2720 libguile/versiondat.h and ice-9/version.scm are generated directly
2721 by the configuration process, rather than having version.scm
2722 generated directly, and libguile/versiondat.h generated by the
2723 Makefile, which is generated by configure. It seems that
2724 sometimes the Makefile would change, but versiondat.h depends on
2725 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2726 * Makefile.am (versiondat.h): Target removed; this is generated
2727 directly by the configure script now.
2728 (BUILT_SOURCES): Remove versiondat.h.
2729 * versiondat.h.in: New file, transformed by the configure script
2731 * Makefile.in: Regenerated.
2733 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2734 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2735 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2736 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2737 if we want to use them in a header file some day, we can. (Thanks
2738 to Michael Livshin.)
2740 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2741 SCM numbers, so we won't have rollover problems; the range of a
2742 signed long in milliseconds is about 25 days. (Thanks to Karl
2745 Don't redefine sleep and usleep; fix this problem now.
2746 * coop.c (sleep, usleep): Remove declarations; we don't use or
2747 redefine these any more.
2748 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2749 job of usleep and sleep in a thread-friendly way. We can use
2750 these in the rest of Guile. Define versions for systems both with
2751 and without iselect.
2752 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2753 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2754 we're just using it, not redefining it, we can use a K&R style
2756 (sleep): Declare this, too, if the system hasn't.
2757 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2758 scm_uthread_sleep if they're available; otherwise, just call the
2760 * scmconfig.h.in: Regenerated.
2762 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2764 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2766 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2768 * threads.c: Doc fix.
2770 The argument type of usleep varies from system to system,
2771 as does the return type. We really shouldn't be redefining usleep
2772 at all, but I don't have time to clean that up before the 1.3.
2773 release. It's on the schedule for afterwards. (Thanks to Julian
2775 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2777 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2778 * scmconfig.h: Regenerated.
2780 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2781 right way to handle system variation. Autoconf's approach is the
2783 * simpos.h (scm_software_type): Declaration deleted.
2785 * script.c (scm_find_executable): Don't test if unix is #defined
2786 here; first, NetBSD doesn't #define it, and second, it's the wrong
2787 way to go about these things. (Thanks to Perry Metzger.)
2788 (dld_find_executable): Delete this MSDOS support code. This isn't
2789 the way we want to support this; it needs to be rethunk at a
2792 * genio.c (scm_do_read_line): Don't just politely check that the
2793 line was either non-empty or EOF. Abort if it's empty and not
2796 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2798 * scmconfig.h.in: Regenerated.
2800 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2803 * genio.c (scm_do_read_line): Count lines correctly when the file
2804 doesn't end in a newline.
2806 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2808 * genio.c (scm_do_read_line): Maintain the line count correctly.
2809 (Thanks to Harvey J. Stein and Greg Harvey.)
2811 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2814 * numbers.c (big2str): Protect t from garbage collection until
2815 we're done. (Thanks to Gary Houston.)
2817 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2819 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2821 * Makefile.in: Regenerated.
2823 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2824 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2827 Do magic to mix reads and writes on stdio FILE-based ports.
2828 (Thanks to Christian Lynbech.)
2829 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2831 (pre_read, pre_write): New functions.
2832 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2833 local_fputs): Call them.
2834 (local_fflush): Mark the port as ready for reading and writing.
2835 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2836 flags on new port objects. This might not be accurate --- who
2837 knows what state the FILE * is in when we get it --- but it won't
2838 do extraneous calls to fflush or fseek, so it's no worse than the
2839 behavior before this change.
2840 * ports.h: Add comment.
2842 Centralize the creation of port objects based on stdio FILE * in
2843 fports.c; don't just throw them together anywhere.
2844 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2845 what the rest of Guile wants. Don't set the revealed count;
2846 that's only appropriate for stdin, stdout, stderr.
2847 (scm_standard_stream_to_port): This function does set the revealed
2849 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2850 not scm_stdio_to_port.
2851 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2852 * fports.c (scm_open_file): Same.
2853 * posix.c (scm_pipe): Same.
2854 * socket.c (scm_sock_fd_to_port): Same.
2855 * ioext.c (scm_fdopen): Same.
2856 (scm_freopen): Moved from here to...
2857 * fports.c (scm_freopen): ... here. This is really something that
2858 munges the internals of an fport, so it should go here.
2859 * fports.h (scm_stdio_to_port): Adjust prototype.
2860 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2861 * ioext.h (scm_freopen): Prototype removed.
2863 * filesys.c (set_element, get_element): This can work on both pipe
2864 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2867 * scmconfig.h.in: Regenerated.
2869 Change the definition of the functions in scm_ptobfuns so that
2870 they get passed the port object, not the port's stream.
2871 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2872 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2873 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2874 Pass the port itself to the scm_ptobs function.
2875 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2876 scm_generic_fgets): Same.
2877 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2878 getc_void_port, fgets_void_port, close_void_port): Just change the
2879 argument names; these functions don't really do anything.
2880 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2881 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2882 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2883 Also, use prototyped definitions, and get rid of the extra
2885 (scm_fptob, scm_pipob): We don't need casts here any more.
2886 * strports.c (prinstpt): Use prototype declarations.
2887 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2888 and use SCM_STREAM to get the string info. Also, use prototyped
2889 definitions, and get rid of the extra declarations.
2890 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2893 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2894 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2896 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2897 scm_fgets, for consistency.
2898 (scm_fptop, scm_pipob): References updated.
2900 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2902 Include the source location in error messages for scripts.
2903 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2904 stack is still there when we catch the error.
2905 * throw.c (handler_message): If we are handling an error with a
2906 message, then put together the proper arguments and call
2907 scm_display_error, instead of scm_display_error_message. That
2908 displays source location, if it can find it.
2910 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2912 * gc.c (scm_unprotect_object): Change this so that calls to
2913 scm_protect_object and scm_unprotect_object nest properly.
2914 (scm_protect_object): Doc fixes.
2916 * strings.c (scm_string_set_x): Require the argument to be a
2917 writable string, not a substring or a symbol.
2918 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2919 (Thanks to John Redford and Charbel Jacquin.)
2921 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2923 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2925 * eval.c (safe_setjmp): Remove this misunderstanding.
2926 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2929 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2931 * libguile.h: Mark these as C declarations, for compilation by C++
2934 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2935 __cplusplus clause. I seriously doubt this ever worked the way
2936 the author seems to have intended.
2938 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2940 Utterly needless cleanups to hopelessly messy code.
2941 * ports.c: Doc fixes.
2942 (scm_fflush): Moved to ...
2943 * genio.c (scm_fflush): ... here, amongst all the other port
2944 method invocation functions.
2945 * genio.h, ports.h: The prototype moves too.
2947 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2949 * backtrace.c (display_error_body): The current frame does not
2950 always have a parent frame; consider a function called directly
2951 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2954 * alloca.c (alloca): Undo yesterday's changes, and simply call
2955 malloc directly for storage, and abort if we don't get what we
2956 want. The situation is much simpler --- just call malloc. Emacs
2957 has bizarre/evil requirements (signal handlers might malloc unless
2958 you set this global flag, so you have to set the flag around all
2959 calls to malloc) which we are certainly not going to conform to,
2960 so we can do the simple and obvious thing.
2962 * coop.c (coop_condition_variable_wait): Make this function
2963 static. It's only useful internally --- you should never just
2964 wait on a condition variable.
2965 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2967 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2969 * unif.c (scm_array_set_x): Accept any kind of number as an
2970 element for a uniform vector of doubles. This is more consistent
2971 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2973 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2974 works; I can't conveniently test it myself. (Thanks to Dvid
2975 Tillman for the bug report.)
2977 * init.c: Doc fixes.
2979 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2980 from here, not from scm_compile_shell_switches (which is a pretty
2981 dumb place to do it).
2982 (scm_load_startup_files): New function.
2983 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2984 * script.c (scm_compile_shell_switches): Don't load the startup
2986 (scm_ice_9_already_loaded): Variable moved.
2987 * init.c (scm_load_startup_files): Prototype for new function.
2988 * gh_init.c (gh_enter): Doc fix.
2990 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2992 Some anti-warning changes from Greg Harvey.
2993 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2994 warnings when it doesn't understand our NORETURN declarations in
2996 * posix.c (scm_mknod): Similar.
2998 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3000 * posix.c (scm_getpwuid): If we can't find an entry, return our
3001 own message, instead of using scm_syserror --- the getpwMUMBLE
3002 functions don't set `errno' to anything interesting.
3004 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3006 Get rid of warnings from the cooperative threading system.
3007 * threads.h (scm_single_thread_p, scm_yield,
3008 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
3009 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
3010 scm_wait_condition_variable, scm_signal_condition_variable): Add
3011 prototypes for these Scheme-visible functions.
3012 * coop-defs.h (coop_next_runnable_thread,
3013 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
3014 Prototypes for these here, even though they're from iselect.c.
3015 (coop_condition_variable_wait, coop_join): Add prototypes.
3016 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
3017 scm_threads_free_condvar): Make these smob functions static.
3018 * coop-threads.h (coop_init): Give this a real prototype.
3019 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
3020 (coop_next_runnable_thread): No need to provide prototype; it's in
3023 * scmconfig.h.in: .detarenegeR
3025 * iselect.c, threads.c: Doc fixes.
3027 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3029 * Makefile.in: Regenerated with a patched automake, to get
3030 dependency generation right when using EGCS.
3032 * inet_aton.c (inet_aton): Add prototype, to remove compiler
3033 warning. (Thanks to Robert Pluim.)
3035 * inet_aton.c (inet_aton): Reassure the compiler that the
3036 arguments to the <ctype.h> macros are all unsigned characters, not
3039 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3041 Getting rid of more warnings...
3042 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
3043 today's change to ../configure.in.
3044 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
3045 * scmconfig.h.in: Regenertaded.de.,.__

3047 (scm_localtime, scm_mktime): Use a const char * to manipulate the
3050 * readline.c: Doc fix.
3051 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
3052 * readline.h (scm_filename_completion_function): Add prototype.
3053 (scm_init_readline): Make this into a prototype.
3055 * readline.c (scm_filename_completion_function): Use SCM_PROC to
3056 declare this, instead of calling scm_make_subr manually.
3058 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
3060 * readline.h (scm_init_readline): Add prototype for this.
3061 (scm_init_readline): Make this a real prototype.
3063 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3065 Warning fixes from Maciej Stachowiak:
3066 * backtrace.h (scm_display_application, scm_backtrace): Add
3068 * debug.c (scm_m_start_stack): Make this function static.
3069 * fluids.h (scm_fluid_p): Add prototype.
3070 * procprop.c (scm_i_procedure_arity): Make this function static.
3071 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3072 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.

3076 * stacks.h (scm_stack_id): Add external prototype.
3077 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3079 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3081 * gh.h: took out the definitions of vset and vref, since they are
3082 replaced by the proper vector routines that correspond to the R4RS
3085 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3087 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3088 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3089 third argument, a C expression that should result in a SCM value,
3090 which is used to initialize the variable. Reimplemented
3091 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3094 * version.h (scm_libguile_config_stamp): Add prototype.
3095 (From Maciej Stachowiak.)
3097 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3099 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3100 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3102 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3104 * print.c (scm_iprin1): Rather than having one i, and using it in
3105 several places, declare a fresh i local to each block where it is
3106 used, and give it a signedness appropriate to its use in each case.
3107 (scm_iprlist): Same.
3109 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3110 comparison warnings.
3112 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3113 signed/unsigned clashes.
3115 * posix.h (scm_tmpnam): Added prototype.
3117 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3118 scm_make_subclass_object): Add external prototypes.
3120 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3121 comparison is okay here.
3123 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3125 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3126 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3128 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3131 * load.c (swap_port): Make this function static.
3133 * load.c (scm_search_path): Make max_path_len and max_ext_len
3134 unsigned, since they're compared against string sizes.
3136 * load.c (init_build_info): Make i unsigned.
3138 * ioext.h (scm_read_line): Add prototype.
3140 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3141 scm_hash_fn_remove_x): Make hash bucket index local variable k
3142 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3143 accurately as possible.
3145 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3146 comparisons, and range checking to make sure those casts are
3149 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3150 signed/unsigned comparisons.
3152 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3153 avoid signed/unsigned comparisons.
3154 * smob.h (scm_numsmob): Change extern declaration to match.
3156 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3157 avoid signed/unsigned comparisons.
3158 * ports.h (scm_numptob): Change extern declaration to match.
3159 (scm_current_load_port, scm_set_port_line_x,
3160 scm_set_port_column_x): New prototypes.
3162 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3163 test code, and it causes warnings.
3165 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3166 gh_uniform_vector_ref): Added prototypes.
3168 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3169 debugging support unconditionally. That's backtrace.c, stack.c,
3170 debug.c, and srcprop.c.
3171 (EXTRA_libguile_la_SOURCES): Omit those from here.
3172 * Makefile.in: Regenerated.
3174 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3176 * options.c (scm_options): Bugfix: Allow empty list of options!
3178 * debug.c, debug.h (scm_single_step): Removed.
3179 (scm_with_traps): New procedure. This procedure could easily be
3180 written in Scheme but needs to be highly optimized.
3182 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3184 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3185 Check SCM_TRAPS_P before trapping.
3187 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3189 Changes to avoid signed/unsigned comparison warnings.
3190 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3191 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3192 so they can have appropriate types for each application. Make i
3193 signed. Use initializers in some spots. I'll probably pay for
3195 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3196 (scm_must_realloc): Make nm unsigned.
3197 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3198 (scm_init_storage): Use prototype-style definition, and make the
3200 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3201 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3203 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3204 avoid signed/unsigned comparison warnings, and because the return
3205 value of readlink may be -1. Don't bother casting the third
3206 argument to readlink.
3208 * filesys.c (scm_dirname, scm_basename): Move these to their own
3209 page, at the end of the file.
3210 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3212 * eval.h (scm_eval_options_interface): Add external prototype for this.
3213 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3215 * eval.c (scm_lookupcar1): Make this static.
3217 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3218 Make these prototype declarations, not K&R-style.
3220 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3221 unsigned comparison warning.
3223 * appinit.c: File removed. It had a single function in it, empty,
3224 whose reason for existence is explained in no documentation or
3225 comment. I think it's there as a default for some Tcl-style
3226 initialization, but Tcl abandoned that approach a while ago.
3227 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3228 (BUILT_SOURCES): Remove appinit.x.
3229 * Makefile.in: Regenerated.
3231 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3233 * Makefile.in: Regenerated using the last public version of
3234 automake, not the hacked Cygnus version.
3236 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3238 Remove Totoro kludge.
3239 * Makefile.in, scmconfig.h.in: Regenerated.
3240 * init.c, readline.c: Don't check if TOTORO is #defined.
3242 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3244 * Makefile.am: Adjust for new thread configuration system.
3245 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3246 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3248 (THREAD_LIBS): Definition deleted; automake will generate such
3249 things automatically.
3250 * Makefile.in: Regenerated.
3252 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3254 Simplify smob and port marking; set the mark bit in the generic
3255 marking code, and make marker routines only responsible for
3256 turning up outgoing pointers.
3257 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3258 before calling the marking function. Don't call the marking
3259 function if it's zero.
3260 * markers.c (scm_mark0): Just return #f. This function isn't
3261 necessary at all now, but it's harmless to call it. We'll leave
3262 it in so other folks' code doesn't croak at link time.
3263 (scm_markcdr): Don't call SCM_SETGC8MARK.
3264 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3265 * dynl.c (mark_dynl_obj): Same.
3266 * root.c (mark_root): Same.
3267 * srcprop.c (marksrcprops): Same.
3268 * unif.c (markra): Same.
3269 * variable.c (scm_markvar): Same.
3270 * ports.c (scm_markstream): Same.
3271 (void_port_ptob): Specify zero for our marking function.
3272 * debug.c (debugobjsmob): Same.
3273 * dynwind.c (guardsmob): Same.
3274 * filesys.c (dir_smob): Same.
3275 * fluids.c (fluid_smob): Same.
3276 * fports.c (scm_fptob, scm_pipob): Same.
3277 * mallocs.c (mallocsmob): Same.
3278 * regex-posix.c (regex_t_smob): Same.
3279 * smob.c (freecell, flob, bigob): Same.
3280 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3281 * throw.c (jbsmob, lazy_catch_funs): Same.
3283 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3285 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3286 scm_copy_tree on code in order not to let memoized code to leak
3287 out. Thus, scm_copy_tree needs to copy vectors as well since
3288 quasiquote can introduce evaluated code also inside vector
3291 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3293 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3295 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3296 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3299 * unif.c: Say that ivect and uvect are of type signed and unsigned
3300 long instead of int in commentary so that it correctly describes
3303 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3305 * stime.c: Removed declaration of strptime. (It should be
3306 declared by the system headers. If it turns out that some systems
3307 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3309 * stime.h: Renamed TIMEH --> STIMEH
3311 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3312 to increase portability, don't use structure assignment.
3313 (Thanks to Nicolas Neuss.)
3315 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3317 (finalize_fd_sets): Added empty statement after last case label.
3318 (Thanks to Nicolas Neuss.)
3320 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3323 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3325 * init.c, readline.c: OK, I won't have these readline.x bug
3326 reports anymore. We've had them since April. The current reason
3327 is a completely unintelligible failure of totoro.red-bean.com to
3328 do the test for rl_getc_function in libreadline correctly. This
3329 kludge overrides the test if we're on totoro so that the snapshot
3330 generation process can work.
3332 * readline.c: Define a strdup replacement if not existent on system.
3334 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3336 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3337 This change makes scm_make_vector R5RS compatible. We cannot keep
3338 the third argument since people want to be able to deduce the form
3339 of the C function call only by looking at R5RS. (At the same time
3340 we have removed some unnecessary complexity!)
3342 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3343 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3344 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3345 argument in call to scm_make_vector.
3347 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3349 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3350 This macro is useful in applications.
3352 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3354 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3355 (scm_parse_path, scm_search_path): New Scheme level procedures.
3357 * load.h (scm_internal_parse_path, scm_parse_path,
3358 scm_search_path): Declared.
3360 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3362 * filesys.c (dirname, basename): New procedures.
3364 * init.c (scm_boot_guile_1): Removed condition around
3367 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3368 new data type (guards) for representation of C level guards and
3369 data on the wind chain.
3370 (scm_internal_dynamic_wind): New function.
3372 * dynwind.h: Declare scm_internal_dynamic_wind.
3374 * root.h (scm_root_state): Added scm_cur_loadp.
3376 * root.c (mark_root): Added comment about cur_loadp.
3378 * load.c: #include "dynwind.h";
3379 (scm_primitive_load): Use scm_inner_dynamic_wind to update
3382 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3384 * ports.c (current-load-port): New procedure.
3386 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3388 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3389 not a tty, return #f.
3391 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3392 to Julian Satchell and Roland Kaufmann.)
3394 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3395 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3397 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3399 * debug.h, debug.c (scm_start_stack): New function. Implements
3400 the guts of old scm_m_start_stack.
3402 * debug.c (scm_m_start_stack): Use scm_start_stack.
3404 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3405 start_stack and restart_stack. (These have static scope.)
3407 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3409 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3410 readline functions to come in release 2.3. (Thanks to Chet
3412 (handle_errors): Use the above functions.
3414 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3416 * readline.c: Improvements for readline support: Handle errors
3417 better; Implement before-read-hook.
3419 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3421 * init.c (scm_boot_guile_1), readline.c: Test for
3422 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3423 assure that we have version >= 2.1.)
3425 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3427 * readline.c (scm_readline): Defer interrupts while we're calling
3430 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3431 away the string to add_history.
3432 (completion_function): Do completion for readline. (Thanks to
3434 (scm_filename_completion_function): New procedure: Filename
3436 (current_input_getc): New function. Use this one instead of
3437 standard getc from readline.
3439 * throw.c, throw.h (scm_handle_by_throw): New function: This
3440 handler throws errors to next handler on the dynwind chain.
3442 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3444 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3447 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3449 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3451 (scm_procedure_properties): Modified to return arity together with
3453 (scm_procedure_property): Added the read-only property `arity'.
3454 (scm_set_procedure_property_x): It is an error to set the `arity'
3457 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3458 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3460 * procprop.h (scm_sym_arity): New symbol.
3462 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3463 to set the dispatch procedure of an operator or entity object.
3465 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3466 Made procedure slots read-only.
3468 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3469 scm_tcs_cons_gloc case in zero args switch; Fixed args
3470 construction for operators in scm_tcs_cons_gloc case in two args
3473 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3475 * fluids.c: Removed use of assert.h (in order to avoid
3478 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3480 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3482 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3483 change makes the evaluator safer at the cost of evaluation speed.
3484 It handles the case when the user has added a non-immediate
3485 improper end of the application form, e.g., `(+ 0 . x)'.
3486 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3487 minimize the extra cost as much as possible. The new code is
3488 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3489 problem with structs planted directly in the code (e.g. by a
3490 macro). This no longer causes segmentation fault. (Thanks to
3493 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3494 arg `proc' in order to be able to throw errors; New argument
3497 * Removed extra #include "debug.h"
3499 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3501 * scmsigs.c: Declare usleep as returning void on some systems.
3502 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3505 * coop.c (usleep): Return void on some systems.
3507 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3509 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3511 * coop.c: Changed return type of usleep to int.
3513 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3514 isn't found in the OS.
3516 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3517 isn't enabled. (Thought that I had made this change ages ago...)
3519 * iselect.c: Declare bzero if not defined by OS.
3521 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3523 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3524 condition. (Thanks to John Tobey.)
3526 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3527 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3530 * __scm.h: Start the long-term project of moving to POSIX threads.
3531 Phase 1: Classification of all critical sections.
3532 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3533 for A sections. (See comments in __scm.h for details.)
3535 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3536 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3538 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3540 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3541 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3542 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3543 dependencies on $(srcdir)/Makefile.in
3544 $(top_builddir)/config.status in order to avoid circularity.
3546 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3547 from argc if argc was 0 initially.
3549 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3550 in generation of libpath.h.
3552 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3554 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3555 libguile from 2 to 3.
3557 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3559 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3561 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3563 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3564 scm_set_port_column_x, scm_port_filename,
3565 scm_set_port_filename_x): Removed optional arguments. Added
3566 proper argument checking.
3568 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3569 stack size in machine words.
3571 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3572 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3573 to Ole Myren Röhne.)
3575 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3577 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3578 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3580 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3583 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3584 procedure apply: Copy argument lists before pushing them unto the
3585 environment so that the environment won't get mutated due to
3586 manipulation of procedure arguments. This should perhaps be
3587 regarded as a temporary solution until someone finds a more
3588 efficient one. (Thanks to Maciej Stachowiak.)
3590 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3592 * script.c (scm_compile_shell_switches): Use "guile" as default
3593 zero arg if argc is NULL.
3595 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3597 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3598 is zero. (Thanks to Dirk Herrmann.)
3600 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3602 * ports.c (scm_add_to_port_table): First line is now line 0
3603 (was 1). (Interface changed according to suggestion by Per
3606 * backtrace.c (display_header): Add 1 to line and column numbers
3607 when presenting them to the user.
3609 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3610 from debug.c --> eval.c
3612 * eval.h, eval.c (scm_eval_options_interface): New options
3614 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3615 i.e. stacks for new threads.
3617 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3619 * eval.c (unsafe_setjmp): Removed with #if 0.
3621 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3624 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3625 to avoid compiler warnings.
3627 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3629 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3631 * throw.c (handler_message): Print message on current error port
3632 instead of default error port. (Thanks to Maciej Stachowiak.)
3634 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3636 * ports.c (scm_add_to_port_table): allocate in units of
3637 struct scm_port_table *, not struct scm_port_table.
3638 * posix.c (scm_close_pipe): remove the port from the port table
3640 Thanks to Rob Engle for both fixes.
3642 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3644 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3645 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3647 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3649 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3651 * backtrace.c (display_error_body, display_backtrace_body),
3652 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3653 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3654 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3655 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3658 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3659 don't receive the jmpbuf arg anylonger.
3660 (scm_catch): Don't accept a #f tag.
3661 (scm_throw): Check that key is a symbol.
3662 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3664 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3666 * async.c (async_pending): Removed declaration.
3668 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3670 * dynwind.c (scm_wind_chain): New debug function.
3672 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3673 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3674 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3675 extra layer of functions around the body and handler of a thread.
3676 This extra layer makes sure that the handler is called in the
3677 dynamic context of the surround (= empty dynwind list), but under
3678 the *dynamic root* of the body. We can not use the dynamic root
3679 of the surround since that root belongs to another thread => stack
3680 is not handled correctly. It may seem ugly to use this extra
3681 layer, but the extra cost in terms of execution time is really
3682 negligible compared to the total amount of time required to create
3683 a thread, and it would reduce maintainability to duplicate the
3684 crucial and complicated steps performed by cwdr.
3686 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3687 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3688 get re-enabled. The important effect of this is that interrupts
3689 are blocked during thread switching so that thread data structures
3690 don't risk getting messed up by an unfortunate signal.
3691 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3692 seems to do more aggressive optimization which actually move
3693 instructions around in these macros in a fatal way. Therefore:
3694 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3695 just superstitious...)
3696 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3697 This macro should be used instead of SCM_ASYNC_TICK since the
3698 latter doesn't do context switches any more.
3700 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3701 instead of SCM_ASYNC_TICK.
3703 * coop.c, iselect.c: Since thread switches are now performed with
3704 interrupts masked, we can't use the old mechanism of delivering
3705 signals immediately when they arrive. Signals must instead be
3706 delivered when the asyncs run *after* the end of the critical
3707 section in scm_internal_select. But this also means after context
3708 switch so that the signal will be delivered to a different thread.
3709 To avoid this, I have changed the protocol of
3710 coop_wait_for_runnable_thread and friends so that they are allowed
3711 to return the original thread. So, if a signal arrives during
3712 scm_internal_select, we won't any longer be forced do a context
3713 switch, but can remain in the same thread and deliver the signal
3716 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3717 scm_asyncs_pending and made it global.
3719 * iselect.c: Small fixes.
3721 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3722 coop_condition_variable_init, coop_condition_variable_wait,
3723 coop_condition_variable_signal): Changed return type from `void'
3724 to `int'. This is to adhere closer to the pthreads interface.
3725 This, in turn, is part of an attempt to provide C versions of the
3726 mutex and condition variable primitives which can be part of a
3727 frontend to COOP or pthreads.
3729 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3730 coop_condition_variable_destroy): New functions.
3732 * coop-threads.c (scm_wait_condition_variable): Use
3733 coop_condition_variable_wait_mutex.
3735 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3736 Definitions moved to coop-defs.h.
3738 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3739 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3740 scm_cond_destroy): New C interface to mutecis and cond vars.
3742 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3744 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3746 * iselect.c: Now several threads can wait on the same file
3747 descriptor. The behaviour is compatible with OS select: All
3748 threads waiting for the fd return with the same status.
3750 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3752 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3753 Can spawn a thread from application C code.
3755 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3757 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3758 gh_doubles2scm): New functions.
3760 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3762 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3763 commented-out version of gh_eval_str()
3765 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3767 * socket.c (scm_bind): free soka after use.
3769 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3771 * stime.c (tzvar): new variable.
3772 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3773 avoid memory leaks when allocating.
3775 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3777 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3780 * gc.c, tags.h: Doc fixes.
3782 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3784 * eval.c (macro-eval!): Removed. This function was a design bug.
3785 It allowed memoized code to leak out to the scheme level. Most
3786 things that you could do with `macro-eval!' can be done with
3789 1997-12-20 Tim Pierce <twp@skepsis.com>
3791 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3792 scm_fgets now depends on ftell(3) to know how many bytes were
3795 1997-12-15 Tim Pierce <twp@skepsis.com>
3797 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3798 dealing with strings.
3800 1997-12-13 Tim Pierce <twp@skepsis.com>
3802 Make %read-line more suitable for implementing read-line efficiently.
3803 * ioext.c (scm_read_line): Strip the terminating newline from a
3804 string, and return a cons of the string and its terminator.
3806 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3807 of the string that is read is stored in this memory location.
3808 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3809 * genio.c, genio.h (scm_do_read_line): Update caller.
3810 * ports.h (scm_ptobfuns): Update typedef.
3811 * fports.c (scm_fptob, scm_pipob): Update struct.
3813 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3815 * filesys.c (set_element): Return file descriptor.
3816 (fill_select_type): Return the highest file descriptor.
3817 (scm_select): Tell select about the highest file descriptor. On
3818 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3819 Therefore the extra overhead for calculating the maximum fd seems
3820 to be more than compensated. Is this correct? In any case,
3821 scm_internal_select will be much faster with this info.
3822 (scm_select, fill_select_type, set_element): Don't accept any kind
3823 of object in the file descriptor list or vector.
3825 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3827 * iselect.c (finalize_fd_sets): Bugfix.
3829 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3831 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3832 when using scm_internal_select (since we might switch to another
3835 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3837 * simpos.c (scm_system): always define: use sysmissing if not
3838 available. Check for HAVE_SYSTEM instead of _Windows (does
3839 Windows lack system or does it have an unusable one?).
3840 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3841 Let the argument be optional: if not supplied, call system(NULL).
3843 * ports.c (scm_close_port): relax the type check from OPPORTP to
3844 PORTP; closing a closed port is allowed.
3846 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3848 * fports.c (scm_fgets): Return if the last char in a chunk is
3849 newline. When fgets returns a string whose length is `size-1', it
3850 is ambiguous whether a whole line was retrieved, so we must check
3851 explicitly whether a line terminator is present.
3853 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3855 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3856 before taking the CDR. (Thanks to Harald Meland.)
3858 * filesys.c (scm_stat): Slightly optimized.
3860 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3862 * ports.c (scm_close_port): Make sure the port is open before
3865 * guile-snarf.in: Pass args through to gcc in a way that preserves
3866 whitespace boundaries. (Thanks to Greg Badros.)
3868 1997-12-02 Tim Pierce <twp@skepsis.com>
3870 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3871 statement. (Thanks to Doug Evans for pointing this out.)
3873 1997-12-01 Tim Pierce <twp@skepsis.com>
3875 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3877 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3879 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3880 errno macro expansion of this field name. (errno is a C
3881 preprocessor macro on some systems.)
3883 1997-11-29 Tim Pierce <twp@skepsis.com>
3885 * iselect.c: Doc fix.
3887 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3889 * init.c (scm_start_stack): Removed initialization of
3890 scm_the_last_stack_var.
3892 * backtrace.h: Declare scm_the_last_stack_var.
3894 * backtrace.c: Define scm_the_last_stack_var.
3896 * root.c (mark_root): Don't mark the_last_stack_var.
3898 * root.h (scm_root_state): Removed the_last_stack_var.
3900 * throw.c: Added #include "fluids.h"
3901 (ss_handler): `the-last-stack' is now a fluid.
3903 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3904 --> the_last_stack_fluid.
3906 * backtrace.c: Added #include "fluids.h"
3907 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3908 (scm_backtrace): `the-last-stack' is now a fluid.
3910 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3911 after scm_init_fluids.
3913 1997-11-28 Tim Pierce <twp@skepsis.com>
3915 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3917 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3918 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3920 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3922 * iselect.c (coop_next_runnable_thread,
3923 coop_wait_for_runnable_thread): Disable interrupts so that no
3924 async is executed before a potential error_revive.
3925 (scm_internal_select): Disable interrupts during the parts of the
3926 code which manipulate the sleep queue and the file descriptors.
3928 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3930 * Makefile.am: Added iselect.c and iselect.h.
3932 * coop.c (coop_qinit): Initialize fields used by
3933 scm_internal_select.
3934 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3935 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3936 replacement in iselect.c.
3937 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3938 coop_join): If GUILE_ISELECT enabled, use
3939 coop_wait_for_runnable_thread instead of
3940 coop_next_runnable_thread.
3941 (usleep, sleep): New replacements for system functions if
3942 GUILE_ISELECT is enabled.
3944 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3946 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3948 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3949 iselect.h. Implement Scheme level `select' using
3950 scm_internal_select. (See NEWS.)
3952 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3954 * init.c: Call scm_init_iselect.
3956 * iselect.h, iselect.c: New files. Implements
3957 scm_internal_select. (See NEWS.)
3959 1997-11-27 Tim Pierce <twp@skepsis.com>
3961 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3962 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3963 and scm_must_free, since ultimately the string returned will be copied
3964 by scm_makfrom0str anyway. Also, read any characters that may have
3965 been pushed onto the port with scm_ungetc.
3966 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3967 * ioext.c (scm_read_line): Free string after Guilifying it.
3968 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
3970 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3972 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3974 * gh.h: Safely wrap prototypes for c++ usage.
3976 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3978 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3979 gh_repl (argc, argv).
3981 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3983 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3984 and to invoke scm_shell().
3985 (gh_launch_pad): took out the loading of boot-9.scm from here,
3986 since it is probably best to let the user control that. In fact,
3987 gh_repl() now invokes scm_shell() which does that.
3989 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3991 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3994 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
3996 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
3997 yesterday's underscore patch. (Thanks to Marius Vollmer for
4000 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
4002 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
4003 DLSYM_ADDS_USCORE is not defined.
4005 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
4007 * gh_data.c (gh_uniform_vector_length):
4008 (gh_uniform_vector_ref): started implementing the uniform types in
4011 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
4013 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
4014 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
4016 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
4018 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
4019 configure.in was changed).
4021 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
4023 * Makefile.am (modinclude_HEADERS): Include readline.h here.
4024 * Makefile.in: Regenerated.
4026 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
4028 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
4029 OPORT is an `open' port, not an output port.
4031 * filesys.c (scm_close, set_element, get_element, scm_chown,
4032 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
4033 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
4034 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
4035 scm_close_port, scm_port_line, scm_set_port_line_x,
4036 scm_port_column, scm_set_port_column_x, scm_port_filename,
4037 scm_set_port_filename_x, scm_port_mode,
4038 scm_close_all_ports_except, scm_set_current_output_port,
4039 scm_set_current_error_port): Likewise
4040 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
4041 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
4043 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
4044 * backtrace.c (display_backtrace_body): Likewise
4045 * fports (scm_setvbuf): Likewise
4046 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

4053 Minor problems with substring-related tag changes.
4054 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
4055 exactly what we want to leave in to detect substrings.
4056 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
4057 * tags.h: Fix diagrams and comments describing the S tag bit;
4058 remove vestigial remarks about the D tag bit.

4060 * strings.c: Formatting tweaks.
4062 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
4063 variable first; then SCHEME_LOAD_PATH, with a warning message.

4072 (scm_boot_guile_1): Call scm_init_readline, if we have it.
4073 * Makefile.am (libguile_la_SOURCES): Include readline.c.
4074 * Makefile.in: Regenerated.
4075 * scmconfig.h.in: Regenerated, after change to ../configure.
4077 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>

4081 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4083 * gh_data.c (gh_vector_set_x): changed name to make it consistent
4084 with the ! -> _x mapping when going from Scheme to C.
4086 1997-10-19 Mark Galassi <rosalia@cygnus.com>
4088 * gh.h (gh_reverse):
4096 (gh_assoc): added these gh_ functions implemented as macros.
4098 * gh_predicates.c (gh_null_p):
4099 (gh_string_equal_p): added these two missing predicates.
4101 * gh_list.c (gh_append):
4106 (gh_set_cdr_x): added these routines as I go through and try to
4107 complete the picture R4RS functions that should be mirrored in the
4110 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4112 * tags.h (scm_tc7_substring): Changed the comment and code to
4113 conform with the changes below. Folks! We have suddenly two new
4114 free tc7 codes!!! Jummy, jummy!

4145 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
4147 Don't include "mbstrings.h".
4148 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
4149 (SCM_SYMBOL_SLOTS): Define as 4.
4150 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
4151 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
4152 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,

4171 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
4172 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
4174 1997-10-12 Mark Galassi <rosalia@cygnus.com>
4176 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
4178 * gh_test_c.c (c_vector_test): some improvements on the vector
4181 * gh.h (gh_vector): this used to exist but do the wrong thing.
4182 Now it (almost) does the right thing, though it takes a list
4183 instead of the individual arguments. I need to see how it could
4185 (gh_list_to_vector): added this function as a macro. Corresponds
4186 to Scheme's (list->vector ...).
4187 (gh_vector_to_list): added this function as a macro. Corresponds
4188 to Scheme's (vector->list ...).
4190 * gh_data.c (gh_vector_ref): renamed from gh_vref to
4191 gh_vector_ref, so that it resembles the Scheme routines more.
4192 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
4193 resembles the Scheme routines more.
4194 (gh_make_vector): this used to be (stupidly) called gh_vector().
4195 This is the right name, since it does the same thing as the Scheme
4196 (make-vector ...) procedure.
4198 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4200 * ports.h: #include "libguile/print.h"
4202 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
4203 Some indentation fixes.
4205 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
4206 longer a user field; New field: class_flags.
4208 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
4210 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
4212 * gh_data.c (gh_bool2scm): new function which replaces
4213 gh_int2scmb(), which is now tagged as obsolete.
4215 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4217 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4218 macros should by convention not test for NIMPness.)
4219 (SCM_COERCE_OPORT): Adjust indentation.
4221 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4222 SCM_NIMP test before SCM_PRINT_STATE_P.
4224 * struct.c, struct.h, gc.c: Renamed:
4225 scm_struct_i_layout --> scm_vtable_index_layout
4226 scm_struct_i_vcell --> scm_vtable_index_vcell
4227 scm_struct_i_vtable --> scm_vtable_index_vtable
4228 scm_struct_i_printer --> scm_vtable_index_printer
4229 scm_struct_i_vtable_offset --> scm_vtable_offset_user
4231 * struct.c (scm_print_struct): Use new printer slot; Default
4232 printing: Also output hex code of vtable so that type identity
4233 will be indicated as well.
4234 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4235 Removed struct_printer_var; Removed struct-vtable-offset;
4236 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4237 vtable-offset-user): New constants.
4239 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
4240 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
4241 If this slot contains a procedure, use that to print structures of
4242 the type represented by this vtable.
4244 * print.c (scm_iprin1): Don't print arguments of macro
4245 transformers. (They are always: exp env.); Bugfix: Unmemoize
4246 transformer source with correct environment.
4248 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4250 Streamlining of call-with-dynamic-root:
4252 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
4253 there is now only one catch.
4254 (cwdr_outer_body): Removed.
4255 (cwdr_handler): New function.
4256 (scm_internal_cwdr): New function to perform the function of cwdr
4257 but take args that are more useful to C code. Also, the handler
4258 is now invoked *outside* of the new dynamic root, like the docs
4259 say. We no longer have to catch absolutely all errors, the caller
4260 is responsible for using a handler that does not throw, if he
4262 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4263 * root.h (scm_internal_cwdr): New prototype.
4265 Even more but risky streamlining:
4267 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4268 allocation of the jumpbuf of a root continuation. The changes
4269 below are controlled by it. They are now deactivated.
4270 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4271 the JMPBUF of the scm_rootcont to NULL before returning.
4273 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4274 when they are non-NULL.
4275 (scm_gc_mark): Likewise, mark only when non-NULL.
4277 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4278 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4280 * gc.c (scm_done_malloc): New function.
4281 gc.h (scm_done_malloc): New prototype.
4283 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
4284 (struct scm_print_state) [revealed]: New field.

4286 type checking purposes.
4287 (scm_valid_oport_value_p): New prototype.
4289 * print.c (scm_valid_oport_value_p): New function to check whether
4290 a certain value is acceptable as a port argument.
4291 (scm_print_state_vtable): New variable.
4292 (scm_free_print_state): Set `revealed' field to false.
4293 (scm_iprin1): Call user supplied closure printer with
4294 scm_printer_apply. Print in the traditional way when there isn't
4295 one or when it returns #f.
4296 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4297 Accept a port/print-state pair in addition to just a port.
4298 (scm_prin1): Don't return the print_state to the pool when it has
4300 (scm_printer_apply): Set `revealed' field of print_state to true.
4301 (scm_init_print): Set scm_print_state_vtable.
4302 (print_state_fluid, print_state_fluid_num): Removed.
4304 * throw.h (scm_handle_by_proc_catching_all): New prototype
4305 throw.c (scm_handle_by_proc_catching_all): New function
4307 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4309 * Makefile.in: Regenerated with automake 1.2c.
4311 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4313 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4314 was looping endlessly.
4316 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4318 * strports.c (scm_eval_string): Don't close the port.
4320 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4321 former returns a nice normal integer. (Thanks to Daniel
4324 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4326 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4327 makefile variable as a build parameter called LIBS. The
4328 build-guile program will use this, for the time being.
4329 * Makefile.in: Regenerated.
4331 Thanks to Shiro Kawai:
4332 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4333 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4336 * Makefile.in: Regenerated with automake 1.2a.
4338 * script.c (scm_compile_shell_switches): If we hit the -c or --
4339 arguments, don't set the car of (command-line) to scm_usage_name,
4340 the prettified name of the guile executable; give it the full
4341 path, the way shells usually handle $0.
4343 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4345 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4346 Scheme-level name `array-map' and renamed `serial-array-map' to
4347 `serial-array-map!'.
4349 * backtrace.c: Introduced exception handlers which now enclose
4350 `display-error' and `display-backtrace' so that error reporting
4351 won't get into infinite loops if an error occurs during displaying
4352 of the error. This can very easily happen with user supplied
4353 print call-back routines.
4355 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4357 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4358 the names `serial-array-map' and `array-map' should be removed.)
4360 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4362 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4363 Added #include "objects.h"
4365 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4366 Add #include "feature.h".
4368 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4369 (modinclude_HEADERS): Added objects.h.
4371 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4372 This test is needed at many places in the code and should be
4373 abstracted. (Motivated by the need of this test in libguiletk.)
4375 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4376 (scm_eval_string), load.c (scm_primitive_load,
4377 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4378 Use SCM_EOF_OBJECT_P.
4380 * eval.c (scm_init_eval): Add feature `delay'.
4382 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4384 * scmhob.h: Removed.
4386 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4388 * list.h (SCM_LISTn): New macros. Make list creation in C code
4389 prettier. The idea comes from STk.
4391 * sequences.h, sequences.c, append.h, append.c: Removed. These
4392 files implemented non-R4RS operations which would encourage
4393 non-portable programming style and less easy-to-read code.
4395 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4398 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4399 sequences.h, #include append.h.
4401 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4404 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4406 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4408 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4410 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4412 * eval.c: Added #include "objects.h"
4414 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4417 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4418 adjacent smob numbers.
4420 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4422 * procprop.h: Added declaration of scm_i_inner_name.
4424 * gsubr.c: New global symbol scm_i_inner_name.
4426 * debug.c (scm_procedure_name): Try procedure property
4427 `inner-name' if `name' fails.
4429 * print.c (scm_iprin1): Use scm_macro_name.
4431 * eval.c (scm_m_define): Give names to macros as well; Only the
4432 first top-level definition gives a procedure/macro a name.
4433 Otherwise confusing names can turn up in backtraces.
4434 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4435 `name'; Give names to macros as well.
4437 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4438 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4441 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4443 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4445 (prinmacro): Removed. The code has been moved/merged into print.c
4446 in order to decrease code redundancy. We want macros to print in
4447 a way equivalent to procedures, and it would be silly to duplicate
4448 the required code. (We don't want to maintain two places.)
4449 (macrosmob): Print field is now a NULL pointer.
4451 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4452 scm_macro_transformer): New prototypes.
4453 (scm_tc16_macro): Declared.
4455 * print.c (scm_iprin1): Added code for printing of macros. Macros
4456 are now printed in a way equivalent to procedures.
4458 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4460 * procs.h (scm_closure_p): Added declaration.
4462 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4464 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4465 Shouldn't pass "heap" as the subr name.
4467 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4469 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4470 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4471 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4472 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4473 SCM_BOOL_T. Any non-false value is true.
4475 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4477 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4478 scm_gensym): Added prototypes.
4480 * symbols.c (scm_gensym): New function. This will speed up
4481 certain types of applications (such as macro systems) which
4482 generate lots of symbols.
4484 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4486 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4488 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4490 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4491 specifier, since (2) or (2 . 3) would cause SEGV.
4492 (scm_transpose_array): more argument checking fixes.
4494 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4496 * Makefile.in: Regenerated.
4498 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4500 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4502 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4504 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4506 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4508 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4509 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4512 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4513 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4514 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4515 scm_array_p, scm_array_rank, scm_array_dimensions,
4516 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,

4527 * list.c (scm_list_append_x): Allow non-pair as last argument.
4528 This is consistent with the R4RS append and is probably the
4529 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4531 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>

4551 third argument is now optional.
4553 * posix.c (scm_execl, scm_execlp): make the filename argument
4554 compulsory, since omitting it causes SEGV.
4555 (scm_sync): return unspecified instead of #f.
4556 (scm_execle): new procedure.
4557 (environ_list_to_c): new procedure.
4558 (scm_environ): use environ_list_to_c. disable interrupts.
4559 (scm_convert_exec_args): take pos and subr arguments and
4560 improve error checking.

4564 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4565 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4566 argument to SCM_ASSERT. Furthermore, the name of the function
4567 should be passed as first argument when signalling
4568 SCM_WNA. (Thanks to Thomas Morgan)
4570 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4571 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4572 dispatches on the number of actual args has a default case
4573 reporting an internal error. This is a vestige from a version
4574 that mallocated a SCM vector to hold the arguments. In the
4575 current version this check is too late: if it ever happens we will
4576 have already overstepped the bounds of the array.
4578 Also, the patch [...] adds a check for too many actual arguments."
4580 mdj: Removed check for "internal programming error".
4582 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4584 * gh_io.c (gh_write): New function.

4599 fold in the functionality of scm_primitive_dup.
4600 (scm_primitive_dup): deleted.

4605 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4606 ultrix are defined. Use setvbuf instead of setbuf.

4624 (scm_iprin): If print_state_fluid carries a print_state, use that
4625 instead of creating a new one.

4627 definitions to help with calling printer functions written in
4629 * print.h (scm_printer_apply): New prototype.

4645 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4647 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied

4672 stream has been set.
4673 (scm_duplicate_port): deleted, there's now an implementation in

4727 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4728 the dynamic object data below the linking of the object to avoid
4729 memory leak when the linking code throws an error. Now the code
4730 leaks a whole dynamically linked library when must_malloc throws,
4731 but that should be much less likely.
4733 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4735 Changes to compile under gnu-win32, from Marcus Daniels:

4773 think this is left over from the (eq? '() #f) days.
4775 * read.c (recsexpr): Give this a dummy definition if
4776 DEBUG_EXTENSIONS isn't #defined.
4778 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

4806 turn off REG_EXTENDED.
4807 (scm_init_regex_posix): New regexp/basic symbol.
4808 (REG_BASIC): #define this if it is not already present.

4855 (cwdr_outer_body): New function, to establish the user's handler,
4856 and pass control to cwdr_inner_body.

4868 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4869 the feeling that real thread systems will not need this...

4887 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4888 1:2. Helps avoid confusion between installed and uninstalled libs.
4890 * scmconfig.h.in: Regenerated. (Needed after June 3 change to

4913 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4915 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA

4920 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4921 top of the word, it should be unsigned.
4923 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4924 is defined, to avoid warnings; it's only used in the
4925 conflict-checking code. Which might go away anyway.
4926 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4927 conditionals; put the label definition in an #if too, to stifle
4930 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4931 ChangeLog-threads in the distribution.
4932 * Makefile.in: Regenerated.

4977 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4979 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4980 supplied. (Change from Tim Pierce.)
4982 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4984 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4985 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4986 default and not `()'. `#f' is the canonical non-value in Scheme,
4989 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4991 * struct.c (struct_printer): New variable that holds a handle on
4992 the Scheme variable *struct-printer*. This variable can be set by
4993 Scheme code to override the printing of structures.
4994 (scm_print_struct): If struct_printer is set, call it. If it is
4995 not set, or returns #f, print the structure in the old fashion.
4996 Include "eval.h" for scm_apply.
4998 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
5000 * struct.c (scm_struct_ref, scm_struct_set_x): Use
5001 scm_struct_i_n_words to get the number of fields, not
5002 -scm_struct_n_extra_words.
5004 On the route to fancier struct printing:
5005 * struct.c (scm_print_struct): New function to print a structure.
5006 Include "genio.h" to support it. This function doesn't do
5007 anything interesting right now, but I think it should be here
5009 * struct.h: Include "print.h" and add prototype for
5011 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
5012 print structures ourself.
5014 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5016 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
5017 before applying the handler in case it doesn't return.
5019 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
5021 * scmsigs.h, async.h: updated.
5023 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
5026 * posix.c (scm_uname): interpret only negative values as an error.
5027 Solaris normally returns a positive value.
5029 * script.c (scm_compile_shell_switches): if we are not going into
5030 an interactive repl, set scm_mask_ints to zero so that asyncs can
5033 * simpos.c (scm_system): don't ignore/unignore signals around
5036 * posix.c (scm_open_pipe): don't ignore/unignore signals around
5039 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
5040 done in boot-9.scm instead.
5042 * scmsigs.c, async.c: Major rewriting of signal handling code.
5043 (scm_sigaction): new procedure.
5044 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
5046 (scm_raise): return unspecified, throw error on failure.
5048 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5050 * regex-posix.c (scm_init_regex_posix): Register the "regex"
5051 feature, to help boot-9.scm decide whether to import the regex
5054 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5056 * eval.c: Include scmconfig.h at the beginning of the file so that
5057 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
5060 * regex-posix.c: #include "_scm.h" before conditionally #including
5061 <regex.h>; the former defines HAVE_REGCOMP.
5063 * regex-posix.c: #include <regex.h> conditionally, so the file is
5064 CPP'able (for dependency scanning) even on systems that don't have
5067 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5069 Add new R4RS-compliant syntax for keywords.
5070 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5071 regardless of the setting of the `keywords' read option.
5072 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5073 can be re-read no matter what the setting of the `keywords' read
5076 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5078 Add support for POSIX regular expressions.
5080 * regex-posix.c, regex-posix.h: New files. (Some code
5081 is taken liberally from rx/rgx.c in the old Guile dist.)
5083 * init.c: Include regex-posix.h.
5084 (scm_boot_guile_1): Call scm_init_regex_posix.
5086 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5087 Add regex-posix.[ch] sources.
5088 * Makefile.in: Regenerated.
5090 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5091 to do this automatically? It didn't for me, bleh.)
5093 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5095 * fports.c (print_pipe_port): New function.
5096 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5097 latter doesn't even take the right arguments.
5099 * Makefile.am: Increment shared lib revision number. I think
5100 sometimes the uninstalled Guile finds the installed shared lib;
5101 Gord says doing this might help. As things turned out, I can't
5102 say whether it does.
5103 * Makefile.in: Regenerated.
5105 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5106 passing it as the closure argument to scm_boot_guile. (Bill
5109 * ports.c (print_void_port, putc_void_port, puts_void_port,
5110 write_void_port, flush_void_port, getc_void_port, close_void_port,
5111 noop0): Use ANSI prototypes instead of K&R declarations, so the
5112 initialization of void_port_ptob gets aggressively type-checked.
5113 Fix arguments of print_void_port and write_void_port. (Bill

5147 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5149 * script.c (scm_find_executable): Use prototype-style definition
5150 here; apparently it's not quite right to have const in a prototype
5151 and then use a K&R declaration. I wonder if stuff like this will
5152 go away if we compile with -Wrequire-prototypes, or whatever that
5153 is... (Bernard URBAN)
5155 * scmhob.h: New text from Bernard URBAN.
5157 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5159 * script.c: Don't #define const on hpux. Configure takes care of
5160 this. (Thanks to Larry Schwimmer.)
5162 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5163 decide whether to #include <unistd.h>, instead of listing a bunch
5164 of systems. Don't #include stdio twice. Removed dyked-out
5165 definition of scm_find_impl_file.
5167 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5169 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5170 library version info to 1:0.
5171 * Makefile.in: Regenerated.
5173 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

5177 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5178 throw.c: Update copyright years; these files have been worked on
5179 significantly in 1997, but only had copyright years for 1996.
5180 Also, change name of copyright holder on some from Mikael
5181 Djurfeldt to Free Software Foundation; he has signed papers
5182 assigning the changes to the FSF.
5184 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5185 reason not to give the user the option.
5187 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5188 Return #f on end-of-file when scanning table (i.e. when called
5189 with no arguments). Try to catch errors, when we can.
5190 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5192 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5193 external declarations. These are useful.
5195 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5197 * posix.c: don't include <sys/select.h> or define macros for
5198 select, since they were not used in this file.
5200 * filesys.c (scm_select): make the fifth parameter microseconds,
5201 not milliseconds. let the fourth parameter be either a real value
5202 or an integer or #f. The first, second and third arguments can
5203 now be vectors: the type of the corresponding return set will be
5205 (set_element, get_element): new static procedures.
5207 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5209 * strports.c (scm_eval_string): New function.
5210 (scm_eval_0str): Trivially re-implemented in terms of
5212 * strports.h (scm_eval_string): New extern decl.
5214 * net_db.c (h_errno): Add extern decl for this.
5216 * fports.c (local_pclose): New function.
5217 (scm_pipob): Use it in the initializer here.
5220 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5221 Use a meaningful error message when signalling an error. For
5222 this, scm_gethost must check h_errno rather than errno.
5224 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5226 * Makefile.in: Regenerated, using automake-1.1p.
5228 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5230 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5231 not SCM_UNSPECIFIED.
5233 * script.c (scm_compile_shell_switches): don't append (quit) if
5235 (scm_shell): call scm_exit_status and exit on the result of the
5238 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5240 Ensure that shared substrings are handled properly when passed to
5241 a system call or other foreign function. Many thanks to Tim
5243 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5244 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5245 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5246 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

5248 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5249 (scm_display_error_message): use RO macros when strings may be RO.
5250 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5251 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5252 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

5256 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
5257 scm_strftime), vports.c (scm_make_soft_port): use
5258 SCM_COERCE_SUBSTR to make sure shared substrings are
5261 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5263 * error.c (scm_error): Add newline to error message.
5265 * init.c (scm_init_standard_ports): Doc fix.
5267 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5269 * dynl-shl.c: Completely replaced with new code from Bernard
5272 * script.c (scm_ice_9_already_loaded): New variable.
5273 (scm_compile_shell_switches): Use it.
5275 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5277 * filesys.c (scm_input_waiting_p): add missing third argument to
5280 * stime.c (scm_localtime): copy the result of localtime before
5281 calling gmtime in case they share a buffer.
5282 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5285 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5287 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5289 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5291 * Makefile.am (check-local): New target, which causes 'make check'
5292 to run gh_test_c and gh_test_repl, with some trivial input.
5293 * Makefile.in: Rgnrtd.
5295 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5297 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5300 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5302 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5303 sure how this was supposed to work.
5304 (scm_async_click): don't send SCM_TICK_SIGNAL.
5305 (scm_init_async): don't initialize %tick-thunk.
5307 * the following change doesn't affect the Scheme interface:
5308 gc-thunk is called at the end of garbage collection. however it's
5309 no longer implemented by pretending it's a signal.
5311 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5312 system async corresponding to scm_gc_thunk.
5313 * async.h: declare scm_gc_async.
5314 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5315 gc-thunk directly, instead of going through a signal handler.
5316 (scm_gc_async): new variable, points to the GC system-async.
5317 (scm_init_async): save the GC async as scm_gc_async instead
5318 of using system_signal_asyncs.
5319 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5321 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
5323 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
5324 Don't screw up if we're interrupted.
5325 * Makefile.in: Regeneradet.
5327 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5329 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5331 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5332 we're not using AM_INIT_GUILE_MODULE any more.
5333 * Makefile.in: Reneregated.
5335 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5337 Functions for finding variable bindings, grace à Tim Pierce.
5338 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5339 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5341 Get 'make dist' to work again.
5342 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5343 * Makefile.in: Regenerated, like a surry without a fringe on top.
5345 Changes for reduced Guile distribution: one configure script,
5347 * configure.in, configure: Removed.
5348 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5349 real configure script lives.
5350 * Makefile.in, scmconfig.h.in: Regenerated.
5352 * init.c: #include "script.h", to get prototype for script.c's
5355 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5357 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5358 scm_must_malloc, not raw malloc.
5360 * script.c (scm_compile_shell_switches): Dyke out debugging output
5363 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5365 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5367 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5368 system has them. Hope this is safe. Previously
5369 sys/timeb.h was included if HAVE_FTIME was defined or if
5370 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5371 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5373 * ioext.c (scm_setfileno): add missing third argument to
5374 scm_misc_error call.
5376 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5378 * eq.c (scm_equal_p): Correctly compare strings of different
5379 varieties. (Thanks to Tim Pierce.)
5381 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5383 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5384 #! block comment must occur on a line all by itself.
5386 Move most of the guts of shell command processing into libguile,
5387 so guile.c can be very small (and eventuallly auto-generated. (I
5388 mean, generated mechanically, not self-generated. Hmm.))
5389 * guile.c, script.c, script.h: New source files.
5390 * init.c (scm_boot_guile_1): Call scm_init_script.
5391 * libguile.h: #include "script.h".
5392 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5393 targets, for new executable.
5394 (libguile_la_SOURCES): Mention script.c.
5395 (modinclude_HEADERS): Add script.h.
5396 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5397 not dynamic linking is enabled. This is because we're generating
5398 executables now. Move CY_AC_WITH_THREADS call after those, so the
5399 values of cy_cv_threads_libs captures the libs chosen above.
5400 * Makefile.in, configure, aclocal.m4: Regenerated.
5402 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5403 We don't maintain this interface any more, and it just confuses
5406 * alloca.c: #include <scmconfig.h>, not <config.h>.
5407 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5408 it'll get included in disties.
5410 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5412 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5413 be distributed, because they confuse people.
5414 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5416 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5418 * configure.in: check for presence of gethostent (not present on
5419 OpenBSD by default).
5420 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5421 * configure, scmconfig.h.in: Regenerated.
5423 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5425 * backtrace.c (scm_backtrace): Split message string across
5426 newlines properly. GCC is more tolerant of this than other
5429 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5431 Merge threads directory into libguile.
5432 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5433 threads.h: New source files.
5434 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
5435 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c

5439 coop-threads.c.cygnus, coop-threads.h.cygnus.
5440 * configure.in: If we're using threads, include threads.o in
5442 * _scm.h, libguile.h: threads.h lives in this directory now.
5443 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5444 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5445 currently used, but brought along for information's sake.
5446 * ChangeLog-threads: log from old 'threads' directory.
5447 * Makefile.in, configure: Rebuilt.
5449 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5451 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not

5456 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5458 Merge GH interface library into libguile.
5459 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,

5461 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5462 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5464 (EXTRA_libguile_la_SOURCES): ... here.
5465 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5466 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5467 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5468 New variables, describing how to build the gh test programs.
5469 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5470 build the test programs, and we probably should have been linking
5471 libguile.la against them all along, to support AIX shared libs.
5472 Add cflags for threads to CFLAGS; add libs for threads to new
5473 variable THREAD_LIBS, used in Makefile.am.
5474 * ChangeLog-gh: log from old `gh' subdirectory.
5475 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5477 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5479 * acconfig.h: Undo change of Apr 9; including the definition of
5480 PACKAGE in the guile headers conflicts with applications' own
5482 * scmconfig.h.in: Regenerated.

5493 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5495 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5496 have S_IFSOCK. This is the case under Ultrix.
5498 * posix.c (scm_status_exit_val, scm_status_exit_val,
5499 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5500 Ultrix versions of WIFSTOPPED, etc., which assume that their
5501 arguments are lvalues (hmm).
5503 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5505 * eval.c: Doc fixes.
5507 * throw.c: Doc fixes; rearranged.
5509 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5511 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5513 * acconfig.h: Added entry for PACKAGE.
5514 * scmconfig.h.in: Regenerated.
5516 Changes to work with automake-1.1n, which has better libtool support.
5517 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5518 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5520 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5522 * Makefile.in: Rebuild.
5524 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5526 * stime.c (scm_mktime): take an optional zone argument.
5527 (scm_localtime): check putenv return value.

5531 (bdtime2c, setzone, restorezone): new static procedures.
5532 (scm_mktime, scm_strftime): use them.
5533 (scm_strftime): don't call mktime before strftime. Use
5534 filltime for return value.
5535 (filltime): convert NULL zname to #f.
5536 (scm_strptime): return a count of characters consumed, not
5537 the remaining string.

5550 * stime.c (scm_init_stime): don't define ticks/sec.
5551 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5552 return value problem and is still portable.)
5554 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5556 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5557 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5558 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5559 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5560 cpp_err_symbols.c): Corresponding changes.
5561 * Makefile.in: Regenerated.

5565 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5566 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5567 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5568 * putenv.c: new file, from sh-utils 1.12.
5570 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5571 since allocation isn't for Scheme objects.
5572 (scm_putenv): copy strings before placing in the environment.
5574 * stime.c (scm_current_time): throw an error if time returns -1,
5575 instead of returning #f.
5576 (scm_get_internal_real_time, scm_get_internal_real_time): use
5577 scm_long2num for return value instead of SCM_MAKINUM.
5579 * stime.h: prototypes updated.
5581 * stime.c (scm_time_in_msec): apparently unused, deleted.
5583 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5585 * configure.in: check for gettimeofday.
5587 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5588 which may be more usefully portable than a gettimeofday interface.
5590 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5592 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5594 * Makefile.in: Regenerated.
5596 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5598 * stime.c (filltime): recovered static procedure.
5599 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5602 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5603 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5605 * posix.c (scm_mknod): split the mode argument into type and perms
5606 arguments, like the extra fields returned by stat.
5608 * fports.c (scm_pipob): set the close, free and print procedures.
5609 (scm_close_pipe): new procedure.
5611 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5612 define them in boot-9.scm
5614 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5616 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5617 wan't defined. Don't include fd.h.
5619 * Previously fd.h was regenerated whenever configure was run,
5620 forcing a couple of files to be recompiled.
5622 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5623 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5624 Check for _fileno as well as _file.
5626 * ioext.c: don't fd.h.
5627 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5630 * Change the stratigy for getting information about errno
5631 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5632 generating lists of symbols during the build process, which will
5633 not always work, include comprehensive lists in the distribution.
5634 To help keep the lists up to date, the "check_signals" and
5635 "check_errnos" make targets can be used.
5637 * configure.in: don't check for a command to extract errno codes.
5638 * Makefile.am: update file lists, remove errnos.list and errnos.c
5639 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5640 check_errnos targets.
5641 (CLEANFILES): remove errnos.c and errnos.list, add
5642 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5643 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5644 * errnos.default: deleted.
5645 * cpp_signal.c: new file.
5646 * cpp_errno.c: renamed from errnos_get.c.
5647 * cpp_err_symbols, cpp_sig_symbols: new files.
5648 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5649 * error.c (scm_init_error): #include cpp_err_symbols instead of
5651 * posix.c (scm_init_posix): don't intern signal symbols. #include
5654 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5656 * strop.c (scm_i_index): allow the lower bound to be equal to the
5657 length of the string, so a null string doesn't always give an error.
5659 * posix.h: new prototypes.
5660 * posix.c (scm_status_exit_val, scm_status_term_sig,
5661 scm_status_stop_sig): new functions, as in scsh. They break down
5662 process status values as returned by waitpid.
5664 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5666 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5667 configure doesn't know about it.
5669 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5671 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5673 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5674 which defines C variables with global linkage.
5676 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5678 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5681 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5683 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5684 has time to check why this doesn't work well with continuations.
5686 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5688 * Fix shell syntax error; some shells won't tolerate
5689 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5691 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5693 * posix.c (scm_uname): throw an error if uname fails instead
5696 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5698 * error.c (err_head, scm_errno, scm_perror): obsolete procedures

5703 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5705 * acconfig.h: Removed PACKAGE.
5707 * scmconfig.h.in: Regenerated.
5709 * snarf.h: g++ says it's non-portable not to specify the first
5710 argument in a varargs declaration. I introduced the first
5711 argument by using preprocessor conditionals.
5713 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5715 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5716 (scm_freopen): use RO string macros for filename and modes.
5717 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5719 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5720 (scm_mknod): use RO string macros for path.
5722 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5723 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5725 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5726 use SCM_ROSTRINGP and SCM_ROCHARS.
5728 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5730 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5733 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5734 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5735 support for byte vectors.
5737 * print.c (scm_iprin1): Limit number of vector elements printed
5738 according to pstate->length.
5740 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5742 * backtrace.c (scm_display_error_message): don't segv if message
5745 * error.h: prototype for scm_error_scm.
5747 * error.c (scm_error_scm): new procedure, reimplements scm-error
5748 in C and uses scm_error.
5750 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5752 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5753 pointer to the Scheme variable read-hash-procedures and intern it
5754 in scm_init_read. Modify scm_read_hash_extend and
5755 scm_get_hash_procedure to use the pointer.
5757 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5759 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5760 (SCM_KEYWORD_STYLE): defined.
5762 * read.c (scm_read_opts): add a keywords option. This isn't a
5763 boolean option, in case someone wants to add support for DSSSL
5765 Setup scm_keyword_prefix symbol.
5766 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5768 I've left keyword support disabled by default, since it doesn't
5769 seem to break the module system and it gives R4RS standard behaviour.
5770 It can be reactivated with (read-set! keywords 'prefix).
5772 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5774 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5775 before constructing arbiter.
5777 * eval.c (scm_m_define): Bugfix: Check that the object is a
5778 closure before setting the procedure property!
5780 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5782 * ports.c: Removed `ungetc-char-ready?'.
5784 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5786 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5787 (idea from Mikael: make it a pair so scm_permanent object only
5789 (scm_read_hash_extend): don't call scm_permanent_object.
5790 (ideas from Mikael): if chr is already in the list, replace its
5791 procedure instead of appending it again. If proc is #f, remove
5793 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5795 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5797 * gdbint.c (gdb_read): update scm_lreadr usage.
5799 * load.h: update prototypes.
5801 * load.c (scm_primitive_load, scm_read_and_eval_x,
5802 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5804 * read.h: add prototype for scm_read_hash_extend. Change args for
5807 * read.c (scm_read_hash_procedures): new variable.
5808 (scm_read_hash_extend): new procedure.
5809 (scm_get_hash_procedure): new procedure.
5810 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5811 for extended # processing.
5812 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5813 scm_read_token): remove case_i, sharp arguments. Change callers.
5815 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5817 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5818 (SCM_CASE_INSENSITIVE_P): define.
5820 * read.c: add case-insensitive option to scm_read_opts.
5821 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5822 to determine whether to convert symbol case.
5823 (default_case_i): definition removed.
5824 * read.c (scm_read_token): if case_i, downcase ic before doing
5827 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5829 * configure.in: Added configuration option `guile-debug'.
5830 Configure with --enable-guile-debug if you want a bunch of extra
5831 functions used for debugging when developing Guile.
5833 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5835 * procs.c (make-cclo): New undocumented debugging procedure: Make
5836 compiled closure with internal procedure PROC and length LENGTH.
5837 Only compiled if GUILE_DEBUG is defined.
5839 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5841 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5843 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5845 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5846 with 3 or more args internally to the evaluator.
5848 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5850 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5851 with 3 or more args internally to the evaluator. This is mainly
5852 because we don't want to pass entry and exit points of the
5853 debug support twice, but it also seems to increase the speed of
5854 the evaluator for such calls (e. g. (+ 1 2 3)).
5856 * backtrace.c (scm_display_application): New procedure:
5857 display-application; Set fancy printing parameters individually
5858 for different types of display (backtrace, error, application).
5859 (These should of course be customizable!)
5861 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5862 clear the CHECK-flags.
5864 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5866 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5868 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5870 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5871 from pairs with a GLOC in the car.
5873 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5874 otherwise `symbol-hash' will behave badly.
5875 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5876 we get segmentation fault!
5878 * symbols.c: Added #include "weaks.h". New functions:
5879 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5880 moved to an extraneous library when we split libguile.)
5882 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5884 * filesys.c (scm_stat): stat now takes fport arguments too as
5885 documented in the manual.
5887 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5889 * debug.c (scm_single_step): Bugfix: Call continuation with
5890 scm_call_continuation instead of throwing to it.
5892 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5894 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5895 argument wasn't declared to be optional.
5897 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5899 * stime.c (scm_init_stime): Add feature "current-time".
5901 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5903 * throw.h: prototype for scm_exit_status.
5904 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5905 args to derive an exit status. Allows (quit) to work from a
5907 (scm_exit_status): new function.
5910 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5912 * eval.c (scm_deval): Removed some old code.
5913 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5915 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5918 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5921 * procs.c: Introduce the existent C function scm_thunk_p at the
5922 Scheme level as well.
5924 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5926 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5927 used from C to easily lookup the value of a symbol in the current
5930 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5932 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5933 scm_init_unif in this file. This will also fix a previous problem
5936 * configure.in: Added AM_MAINTAINER_MODE
5938 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5940 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5943 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5945 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5946 source files that are not always included in libguile but should
5947 have their dependencies calculated by automake. This variable is
5948 recognized by automake, no further magic is needed.
5949 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5950 to deal exclusively with *.lo files, as it seems. The *.o files
5951 are built automatically when the corresponding *.lo file gets
5954 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5956 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5959 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5961 * unif.c (scm_array_set_x): minor change to argument error checking.
5963 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5965 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5966 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5967 They should only be included in the library at configure.in's
5969 (libguile_la_LDADD): Include the appropriate .lo files here.
5970 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5971 so we know when to build them (and their .lo bretheren).
5972 * configure.in (LIBLOBJS): New substituted variable. We let
5973 configure decide which .o files to include in LIBOBJS, and then
5974 put the corresponding list of .lo files in LIBLOBJS. The latter
5975 is what we pass to libtool.
5976 * Makefile.in, configure: regenerated.
5978 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5980 * symbols.c (scm_sysintern0): New function. Contains the core of
5981 old scm_sysintern but doesn't take a second value argument.
5982 (scm_sysintern): Now uses scm_sysintern0.
5983 (scm_sysintern_no_module_lookup): Renamed to
5984 scm_sysintern0_no_module_lookup and doesn't take a second value
5985 argument any longer.
5987 * symbols.h (scm_sysintern0: Added declaration.
5989 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5990 scm_sysintern when interning option keys. Otherwise we risk
5991 destroying the values of already interned variables.
5993 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5994 scheme-level boolean (use SCM_NFALSEP).
5996 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5998 (scm_backtrace): New function. (C version of old function from
5999 boot-9.scm) Motivation: Make it possible to display backtraces
6000 without depending on boot-9.scm. (I'm uncertain if this
6001 motivation is good enough...)
6003 * root.h (scm_root_state): Add member the_last_stack_var.
6004 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
6006 * root.c (mark_root): Mark scm_the_last_stack_var.
6008 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
6011 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
6013 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
6014 1. mark_lazy_catch didn't mark the smob.
6015 2. Both functions above have standard variants:
6016 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
6017 free_lazy_catch --> scm_free0.
6019 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
6021 * throw.c (scm_internal_lazy_catch): New function.
6022 (scm_lazy_catch): Rewritten to use it.
6023 (scm_ithrow): Handle the new lazy catch representation.
6024 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
6025 that doesn't have a jmpbuf is a lazy catch clause.
6026 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
6027 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
6028 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
6030 (scm_init_throw): Register the new lazy-catch smob type.
6031 * throw.h (scm_internal_lazy_catch): decl for new function.
6033 * throw.c (scm_internal_catch): Doc fixes.
6035 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
6036 configure.in. Including this might cause problems if applications
6037 that link against libguile include their own copies of alloca, but
6038 if they're using autoconf, they should be adding libguile to LIBS
6039 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
6040 the copy in libguile, and things will be okay. (I think.)
6042 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6044 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
6046 strop.h: move prototypes too.
6048 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6050 * posix.c (scm_init_posix): don't intern EINTR since it's now done
6053 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
6054 etc. I deleted them from filesys.c long ago, but didn't
6055 notice they were here too (although ineffective since
6056 sys/stat.h wasn't included).
6058 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
6060 * eval.c: Don't define alloca in GCC case. gcc will automatically
6061 use __builtin_alloca if appropriate.
6063 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6065 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6066 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6067 that values of automatic variables are preserved. See comments
6068 for safe_setjmp for details.
6070 Change from Thomas Morgan:
6071 * variable.c: Include eq.h.
6072 (var_equal): New function.
6073 (variable_smob): Use var_equal as the discriminator for variables.
6075 * throw.c (s_throw): Remove extraneous declaration.
6077 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6078 * eval.c: Add necessary CPP cruft to support that.
6079 * configure, Makefile.in, scmconfig.h.in: regenerated.
6081 Change from Thomas Morgan:
6082 * procprop.c (scm_procedure_properties): Convert the Scheme
6083 boolean returned by scm_procedure_p into a C boolean before using
6084 it as a condition for SCM_ASSERT.
6085 (scm_procedure_property): Likewise.
6087 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6088 indications of Unixness.
6091 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6093 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6095 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6097 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6098 "unknown # object" error messages.
6100 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6101 (scm_i_index) and declare it static. Add a 'direction' argument
6102 to indicate what way the search should go.
6103 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6105 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6106 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6108 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6110 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6112 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6113 to avoid clash with various scsh forks.
6115 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6117 The following two changes (ramap.c, throw.c) are motivated by the
6118 apparent unportability of forward declarations of static arrays of
6119 the form `static foo bar[];'.
6121 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6122 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6124 * throw.c (scm_throw): Moved above scm_ithrow.
6126 * options.h: Removed the extern declarations of scm_yes_sym and
6127 scm_no_sym since these are static.
6129 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6131 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6133 * Makefile.am: remove AWK=@AWK@.
6134 Add a rule for generating errnos.list.
6135 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6137 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6138 don't extract errnos, just set a variable (avoids the
6139 need to recompile error.c just because configure is run.)
6141 * unif.h: update prototypes.
6142 * unif.c (scm_uniform_array_read,write): change the offset and
6143 length arguments to start and end, for consistency.
6145 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6147 * ioext.h: update prototypes.
6148 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6149 scm_read_line_x, it's a more general procedure using an
6150 interface from scsh. read-line and read-line! are now defined
6152 Note that the new read-line trims the terminator
6153 by default, previously it was appended to the returned string. An
6154 optional argument specifies how to process the terminator (scsh
6155 compatible). For the old behaviour: (read-line port 'concat).
6156 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6157 returns a pair, but is converted to multiple values if the scsh
6160 socket.h: update prototypes.
6161 * socket.c (scm_recvfrom): for consistency with other procedures,
6162 take start and end as separate optional arguments.
6163 (scm_recv, scm_recvfrom): don't allow the second argument
6164 to be a size, only a buffer. Change the scheme names to
6165 recv! and recvfrom!. Don't return the buffer.
6167 * ioext.h, posix.h: move prototypes too.
6168 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6169 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6170 "read.h" and "unif.h".
6171 * ioext.c: include "chars.h"
6173 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6175 * dynl.c: The dynamic linking and module registration functions
6176 are now defined even when dynamic linking is not available for the
6177 host system. Some of their functionality can be done without
6178 dynamic linking; when it's really needed, they throw errors.
6180 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6182 * configure.in: Only define DYNAMIC_LINKING when one of the system
6183 dependent functions is detected.
6184 * dynl.c (scm_dynamic_func): New function to get the address of a
6185 function in a dynamic object.
6186 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6187 produced by scm_dynamic_func as the thing to call.
6189 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6191 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6192 (scm_register_module_xxx, scm_registered_modules,
6193 scm_clear_registered_modules): New functions.
6195 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6197 * symbols.c (scm_sysintern): Renamed to
6198 scm_sysintern_no_module_lookup.
6199 (scm_sysintern): New function to take the place of the old
6200 scm_sysintern. It uses the current toplevel lookup closure to give
6201 the symbol its value. This is a temporary hack to put packages
6202 like gtcltk into their own module.
6203 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6204 us whether `scm_top_level_lookup_closure_var' has been initialized
6206 * eval.c (scm_init_eval): Set it.
6208 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6210 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6211 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6213 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6215 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6216 scm_sys_dup): deleted: FD capability will be added to other
6218 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6219 scm_fd_free, fd_smob, scm_intern_fd.
6220 (scm_open): renamed from scm_sys_open. Return a port instead of
6221 an FD object. Make the mode argument optional.
6222 (scm_sys_create): deleted, it's just a special case of open.
6223 (scm_init_filesys): move interning of constants O_CREAT etc.,
6224 here (were previously using SCM_CONST_LONG macro).
6225 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6227 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6228 include "fports.h" and <stdio.h>
6229 (scm_stat, scm_select): don't support FD objects.
6231 * error.h: adjust scm_syserror_msg prototype.
6232 * error.c (scm_syserror_msg): take an extra argument for errno.
6233 Using the global value didn't always work, since it could be
6234 reset by procedure calls in the message or args arguments.
6236 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6237 I don't understand why the check was there (and what about the
6240 * strop.c (scm_string_copy): allow shared substrings to be copied.
6242 * unif.h: corresponding change to prototypes.
6243 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6244 recognize two new optional arguments: offset and length. Allow
6245 the port argument to be an integer (file descriptor, for scsh).
6246 Include <unistd.h> for "read" prototype.
6248 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6250 * socket.c: don't include filesys.h.
6252 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6254 * Makefile.am: add AWK=@AWK@ (?)
6256 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6258 Add a rule to generate errnos.c from errnos.
6259 * error.c (scm_init_error): include errnos.c.
6260 * errnos_cnvt.awk: new file, converts the list of errno codes to
6262 * errnos_get.c: new file.
6263 * errnos.default: new file, contains errnos to try if they can't
6264 be extracted from errno.h.
6265 * configure.in: if using GCC, try and extract errno codes from
6269 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6271 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6272 * Makefile.am: Made libguile into a libtool library.
6273 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6274 Set libtool_libs to indicate that libguile is a libtool library.
6275 See guile/ChangeLog for details.
6276 * .cvsignore: ignore "*.lo", the libtool library objects.
6278 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6280 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6281 use htons in getservbyport argument.
6283 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6285 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6286 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6289 * objprop.c (scm_object_property): No need to take the CDR of the
6290 value returned by scm_object_properties, since Aug 20 change.
6292 * configure.in: When checking for struct linger, #include
6293 <sys/types.h> as well as <sys/socket.h>. I've never known
6294 <sys/types.h> to cause any portability problems, and Solaris's
6295 <sys/socket.h> needs it.
6296 * configure: Rebuilt.
6298 I think the Sun compiler has chosen a perverse way to interpret
6299 ANSI declarations combined with K&R definitions. We'll
6300 appease it a little bit. But when it invades France, we fight.
6301 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6302 * print.h (scm_iprlist): Here too.
6303 * numbers.c (scm_divbigdig): Change definition to match
6304 declaration in numbers.h.
6305 * unif.c (scm_makflo): Change definition to match declaration in
6308 * init.c (scm_boot_guile): Don't return the value of
6309 scm_boot_guile_1. This function doesn't return a value;
6310 scm_boot_guile_1 doesn't return a value (or return at all).
6312 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6315 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6316 compile. I have a feeling this function is a bad idea anyway ---
6317 one should always test for features, not systems.
6319 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6320 semicolons. Only pure luck kept this from being noticed earlier.
6322 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6324 * socket.c (scm_recvfrom): Added missing semicolon.
6326 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6328 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6329 the buffer and start and end positions for scsh networking
6332 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6334 * configure.in: Revert previous change to this file; the problem
6335 is due to transient automake weirdness.
6336 * configure: Rebuilt.
6338 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6339 PLUGIN/guile.libs. configure generates the latter from the former.
6340 * Makefile.in: Rebuilt.
6342 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6343 need this if we install scripts, like guile-snarf.
6344 * configure: Rebuilt.
6346 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6348 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6350 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6352 * socket.c (scm_addr_vector): fix faulty scm_listify.
6354 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6356 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6357 style block comment is no longer considered an error.
6359 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6361 * PLUGIN/guile.libs.in: New file.
6362 * PLUGIN/guile.libs: Removed from repository.
6363 * configure.in: Create PLUGIN/guile.libs from
6364 PLUGIN/guile.libs.in. This is for including additonal libraries
6365 needed for dynamic linking.
6366 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6367 instead of PLUGIN/guile.libs.
6369 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6371 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6373 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6374 occurrences of the given element from the list, not just the
6375 first. This is how the Emacs Lisp functions behave, how the
6376 analogous Common Lisp functions behave, and (I believe) how the
6377 older Maclisp functions worked. I realize that this change may
6378 break code, but it seemed better to break it before the Guile
6381 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6382 Their prototypes were already present in gc.h, but they weren't
6384 (scm_init_storage): Initialize scm_protects.
6385 * root.c (scm_protects): New element of scm_sys_protects.
6387 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6389 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6391 * libguile.h: Added #include "libguile/net_db.h".
6393 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6394 30 change. That file is only meant for communication between the
6395 configuration process and load.c. If code linked against libguile
6396 wants to get at the paths mentioned in libpath.h, it can call
6397 functions declared in load.h.
6399 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6401 * libguile.h: Removed #include "libguile/fdsocket.h"
6403 * net_db.c: Added #include <sys/socket.h>.
6405 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6407 * filesys.c (scm_input_waiting_p): use select in preference to
6408 FIONREAD, since the latter doesn't detect EOF.
6409 Throw error if neither select nor FIONREAD available.
6411 * socket.c (scm_connect): take a port, not a fd object.
6412 (scm_fill_sockaddr): throw an error if fam is not recognised.
6413 (scm_bind): use scm_fill_sockaddr.
6414 (scm_listen): take a port, not a fd object.
6415 (scm_accept): take and return a port. return #f in the car if
6416 address can't be got
6417 (scm_sock_fd_to_port): new procedure.
6418 (scm_socket): use scm_sock_fd_to_port.
6419 (scm_addr_vector): throw error if unrecognised address type.
6420 take an extra argument with the calling procedure name.
6421 (scm_getsockname): take a port. return #f if address can't be got.
6422 (scm_getpeername): take a port. return #f if address can't be got.
6423 (scm_recvfrom): take a port. return #f for address component if can't
6425 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6426 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6428 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6430 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6431 use separate data pointers, to allow them to be designed
6432 independently and reused.
6433 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6434 Renamed from catch_body, catch_handler, and uncaught_throw; made
6436 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6438 (scm_catch): Use the above.
6439 (scm_throw): Don't bother printing a message for an uncaught
6440 throw; we establish a default handler in init.
6441 * throw.h (scm_internal_catch): Prototype updated.
6442 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6444 (struct scm_body_thunk_data): New structure, used as data
6445 argument to scm_body_thunk.
6446 * init.c (struct main_func_closure): New structure, packaging up
6447 the data to pass to the user's main function.
6448 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6449 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6450 scm_internal_catch to establish a catch-all handler, using
6451 scm_handle_by_message. This replaces the special-case code in
6453 (invoke_main_func): Body function for scm_internal_catch; invoke
6454 the user's main function, using the main_func_closure pointer to
6455 decide what to pass it.
6456 * root.c (struct cwdr_body_data): Remove handler_proc member.
6457 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6458 (cwdr_handler): Removed.
6460 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6462 * socket.h (SCM_P): update bind prototype.
6463 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6464 include "feature.h".
6465 (scm_socket): return a port, not a file descriptor object.
6466 include "fports.h" and <unistd.h>
6467 (scm_bind): take a port, not a file descriptor object.
6468 take an extra argument for address args.
6470 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6471 INADDR_NONE, INADDR_LOOPBACK.
6473 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6475 * init.c: include net_db.h and not fdsocket.h.
6476 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6478 * Makefile.am: corresponding changes.
6479 * socket.h: renamed from fdsocket.h, fix names.
6480 * net_db.h: renamed from socket.h, fix names.
6481 * socket.c: renamed from fdsocket.c.
6482 remove _sys from procedure names.
6483 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6484 add "socket" to features list.
6485 * net_db.c: renamed from socket.c.
6486 remove _sys from procedure names.
6487 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6488 add "net-db" to features list.
6489 include "net_db.h". don't include <sys/socket.h> or
6492 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6494 * tags.h (scm_tags): Removed comma at end of last enumerator.
6496 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6498 Don't use GCC extensions to allocate space for debugging frames.
6499 (Here he goes again! Why do we put up with this?!)
6500 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6501 an scm_debug_info structure, not an in-line array of them. Add
6502 'info' member, to say how many vect elements we've used, for eval
6504 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6505 a new variable debug_info_end to mark the end of vect, instead of
6506 the address of the 'info' pointer itself.
6507 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6508 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6509 (SCM_APPLY): Explicitly allocate space for debug.vect.
6510 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6511 * stacks.c: Adjusted for new debug frame structure.
6512 (RELOC_INFO, RELOC_FRAME): New macros.
6513 (stack_depth, read_frames): Use them, and new scm_debug_frame
6514 element 'info', instead of magically knowing that eval frames have
6515 an info pointer sitting after vect.
6516 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6518 (scm_init_stacks): Formatting tweaks.
6520 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6522 Give GCC more control flow information, so it can be sure that
6523 variables aren't used uninitialized.
6524 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6525 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6526 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6527 scm_misc_error): Tell GCC that these functions never return.
6528 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6529 out the field type, call abort if SCM_ASSERT returns, to placate
6531 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6532 scm_wta ever returns. We can't handle this case anyway, and this
6533 gives the optimizer more information.
6534 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6535 scm_wta ever returns.
6537 In some cases, the code is fine, but GCC isn't smart enough to
6538 figure that out; this usually happens when one variable is only
6539 initialized and used when a particular condition holds true, and
6540 we know that condition will never change within a given invocation
6541 of the function. In this case, we simply initialize the variables
6542 to placate the compiler, hopefully to a value which will cause a
6543 crash if it is ever actually used.
6544 * print.c (scm_iprin1): Initialize mw_pos.
6545 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6546 * throw.c (scm_ithrow): Initialize dynpair.
6547 * unif.c (scm_uniform_vector_ref): Initialize cra.
6548 * struct.c (init_struct): Initialize prot.
6549 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6551 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6552 if EXPR contains no expressions.
6554 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6556 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6557 cause an infinite loop (???). So much for the algebraic
6558 equivalency of variable-sized arrays and alloca...
6560 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6562 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6563 a SCM boolean, not a C boolean.
6565 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6567 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6568 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6569 rules for raising scm_mtrigger. Previously, unfortunate but not
6570 unlikely circumstances could result in almost constant invokation
6571 of the gc. Now, this situations should be less likely, but they
6572 are not prevented completely.
6574 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6576 * numbers.c (scm_fuck): Procedure removed; looks like old test
6578 * numbers.h: Prototype removed.
6580 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6582 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6583 array to a pointer, to match my Nov 21 change in eval.c.
6585 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6587 * libguile.h: Added #include "libguile/backtrace.h", #include
6588 "libguile/stacks.h".
6590 * strings.c (scm_string scm_make_string scm_string_ref
6591 scm_string_set_x scm_string_equal_p scm_string_append):
6592 Bugfix according to scm patch from Aubrey Jaffer:
6593 Corrected long-standing
6594 (not (eqv? (integer->char 128)
6595 (string-ref (make-string 1 (integer->char 128)) 0)))
6596 bug found by John Kozak <jk@noontide.demon.co.uk>.
6598 * strports.c, strports.h: Make scm_eval_0str return the value of
6599 the last expression evaluated (previously, it returned void).
6601 * strports.c, strports.h: New function: scm_read_0str. Does what
6604 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6606 * simpos.c (scm_getenv): return #f if string can't be found in the
6607 environment instead of throwing an exception, for compatibility
6608 with numerous other systems.
6610 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6612 * Makefile.am (.c.x): Use guile-snarf.
6613 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6615 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6617 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6619 * backtrace.c (scm_display_error_message): Made non-static, and
6620 renamed from display_error_message.
6621 * backtrace.h (scm_display_error_message): Added extern decl.
6622 * throw.c (uncaught_throw): Use it to display the error message.
6624 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6626 * inet_aton.c: Use #if 0, not #ifdef 0.
6628 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6630 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6631 to convert the returned value.
6632 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6633 the offset argument.
6635 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6637 Add new interface to catch/throw, usable from C as well as
6639 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6640 (scm_internal_catch): New function, replaces...
6641 (scm_catch_apply): Deleted.
6642 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6643 mechanism which is a bit more code, but can be used nicely from C
6644 and implement the Scheme semantics as well.
6645 (scm_internal_catch): This is the replacement; it's named after
6646 the analogous function in Emacs.
6647 (scm_catch): Reimplemented in terms of the above.
6648 (struct catch_body_data, catch_body, catch_handler): New
6649 functions, used by scm_catch.
6650 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6651 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6652 support for new cwdr.
6654 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6657 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6659 * acconfig.h: Added DYNAMIC_LINKING symbol.
6660 * configure.in: Add option and checks for dynamic linking.
6661 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6662 dynl.h: New files for dynamic linking support.
6663 * Makefile.am (libguile_a_SOURCES):
6665 (modinclude_HEADERS): Added "dynl.h".
6666 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6668 * init.c (scm_boot_guile_1): Call
6669 scm_init_dynamic_linking to initialize dynamic linking support.
6671 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6673 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6674 (as we Schemers say). It needs to be global, so that I can tweak
6675 it for the proper operation of unexec.
6676 (scm_boot_guile_1_live): New variable, see above.
6678 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6680 * guile-snarf.sh: Removed.
6681 * PLUGIN/guile.libs: Added dependency for -lm.
6682 * acinclude.m4: Renamed from aclocal.m4.
6683 * PLUGIN/greet: Removed.
6684 * Makefile.am, aclocal.m4: New files.
6685 * configure.in: Updated for Automake.
6687 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6689 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6690 and not top_level_lookup_thunk_var.
6692 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6694 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6696 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6698 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6699 Scheme function, instead of syntax. Single argument is now a
6702 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6704 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6705 scm_ra_divide): Properly terminate statements passed as arguments
6706 to IVDEP macros. (Thanks to Bernard Urban.)
6708 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6709 with non-constant sizes. (Thanks to Bernard Urban.)
6711 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6713 It's an "eval closure", not an "eval thunk." A thunk is a
6714 function of no arguments.
6715 * root.h (struct scm_root_state): Renamed
6716 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6717 (scm_top_level_lookup_closure_var): Renamed from
6718 scm_top_level_lookup_thunk_var.
6719 * root.c (mark_root): Uses changed.
6720 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6721 * init.c (scm_start_stack): Uses changed.
6722 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6723 Change scheme-visible name to *top-level-lookup-closure* from
6724 *top-level-lookup-thunk*.
6726 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6728 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6729 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6731 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6733 * gc.c (struct scm_heap_seg_data): Doc fixes.
6735 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6736 sweeping. Then, prepend each segment's free cells to its
6737 freelist, rather than wiping out the old value. (Thanks to Marius
6740 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6741 scm_check_freelist, scm_debug_newcell): New functions and
6742 variables, for debugging freelist problems.
6743 * pairs.h (SCM_NEWCELL): New debugging version added.
6744 * gc.h (scm_debug_newcell): Added extern declaration, used by
6745 debugging version of SCM_NEWCELL.
6747 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6749 On some systems <libc.h> conflicts with <unistd.h>, and should not
6750 be #included at all.
6751 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6752 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6753 * configure.in: Call it.
6754 * posix.c, filesys.c: Use its results to decide whether or not to
6756 * configure, scmconfig.h.in: Rebuilt with autoconf and
6759 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6761 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6762 pointer to the stdio stream before calling scm_setbuf0, so the
6763 latter will be able to retrieve it. I'm surprised this didn't
6764 segfault earlier. (Thanks to Christopher Lee.)
6766 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6768 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6771 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6773 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6774 number of stack narrowing specifier pairs. The first specifier in
6775 a pair controls inner border, the second the outer border. A
6776 number means cut that number of frames, a procedure object means
6777 cut until that object is found in operator position in a frame.
6779 * root.c (cwdr): Bugfix.
6781 * read.c: Recording of positions disabled by default.
6783 * procs.c (scm_closure_p): New function.
6785 * posix.c (scm_tmpnam): New function.
6787 * load.c: Added #include "throw.h".
6788 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6791 * load.c, load.h (scm_read_and_eval_x): New function.
6793 * eval.c: Renamed debug option "deval" to "debug".
6795 (scm_eval_x): `eval!' is no longer accessible from the scheme
6796 level. Motivation: We can't allow operations which introduce
6797 glocs into the scheme level. Guile's type system can't handle
6798 these as data. Use `eval' or `read-and-eval!' as replacement.
6800 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6801 SCM_CONSP since this is a macro!; Set vframe.prev to
6802 scm_last_debug_frame instead of 0. In this way we can look
6803 "above" the virtual start stack frame if we wish.
6804 (scm_debug_hang): New function: Useful for debugging Guile in
6805 certain tricky situations. Will probably be removed later...
6807 * debug.h: Changed semantics of debug option "backtrace". This
6808 option now only indicates whether we want automatic backtrace at
6811 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6813 * ports.c: #include "filesys.h"
6814 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6816 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6817 Motivation: This is system specific code which is related to file
6818 I/O. It also may use select. Added code by Gary Houston to
6819 detect presence of character in stdio buffers.
6821 * libguile.h: #include "libguile/libpath.h"
6823 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6824 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6825 SCM_SITE_DIR; Install libpath.h among the other include files.
6827 * load.c, load.h (scm_sys_package_data_dir): New function.
6829 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6831 * stacks.h: Bugfix: Don't use tail-array length field as stack
6832 length field! This screwed GC.
6834 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6836 * _scm.h: Added #ifndef around definition of macros min and max.
6838 * __scm.h: Added hooks for threads to plugin to in ints protection
6839 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6840 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6841 the main code in these macros duplicated and spread over multiple
6842 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6843 SCM_THREAD_SWITCHING_CODE.
6845 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6847 * snarf.h: New file.
6848 * guile-snarf.sh: New file.
6849 * Makefile.in (inner_h_files): Added snarf.h
6850 (ancillary, install, uninstall, distclean): Added actions for
6852 (.c.x): Use guile-snarf.
6853 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6854 (gen_c_files): Note that these depend on guile-snarf.
6855 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6856 now in "snarf.h". Added #include "snarf.h" to get them.
6857 * libguile.h: Added #include "snarf.h".
6858 (Patches applied and tweaked by Jim Blandy.)
6860 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6862 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6863 standards suggest against providing prototypes for system
6864 functions. Thanks to Greg Troxel.
6866 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6868 * strports.c (scm_eval_0str): New function.
6869 #include "read.h", to get prototype for scm_read.
6870 * Makefile.in (strports.o): Update dependencies.
6871 * strports.h: New prototype.
6873 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6874 scheme name from "int?" to "integer?". It seems to do the job.
6875 * numbers.h: Rename prototype too.
6876 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6879 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6880 scm_num_eq_p): Rename these according to R4RS conventions: call
6881 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6882 to making libguile R4RS compliant without ice-9...
6884 * load.c (scm_sys_search_load_path): Search for files under all
6885 extensions listed in the %load-extensions variable. If FILENAME
6886 is absolute, return it unchanged, without searching the load path.
6887 (scm_loc_load_extensions): New variable, pointing to
6888 %load-extensions' value cell.
6889 (scm_init_load): Initialize it, and the value it points to.
6890 (scm_primitive_load_path): Improve error reporting.
6892 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6893 of new Scheme variable %load-hook.
6894 (scm_primitive_load): Apply %load-hook to filename.
6896 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6898 * configure.in: add tests for figuring out whether buffered data
6899 is available in a FILE structure, which is needed by char-ready.
6901 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6904 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6905 exceptions using misc_error instead of syserror. It seems a bit
6906 odd to throw an exception if a string can't be found in the
6907 environment, but it's consistent with open-file, stat etc.
6908 (simpos.h): remove sys_ from getenv.
6910 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6911 occurs, throw an error instead of returning errno. Return value
6913 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6915 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6917 * filesys.c (scm_stat2scm): derive file type and permissions from
6918 the stat mode and append them to the returned vector.
6919 There isn't much overhead in doing this and it avoids the need to
6920 work with S_IRUSR et al. in Scheme.
6921 Define symbols scm_sym_regular etc.
6922 (scm_init_filesys): don't intern S_IRUSR etc.
6924 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6925 and s_primitive_load_path.
6927 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6929 * error.h: don't declare error symbols. prototype for scm_misc_error.
6931 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6934 * error.c: use SCM_SYMBOL to set up error keys.
6935 scm_misc_error: new procedure.
6937 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6939 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6940 between `#!' and `!#' is ignored.
6941 (skip_scsh_block_comment): New function.
6943 * feature.c (scm_set_program_arguments): New argument, FIRST.
6944 * feature.h: Update prototype.
6945 * init.c (scm_boot_guile_1): Pass new argument to
6946 scm_set_program_arguments.
6948 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6950 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6951 (scm_boot_guile): Call scm_set_program_arguments here, later than
6952 the old initialization.
6954 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6955 initialization procedure.
6956 - Delete in, out, err arguments; there are other perfectly good
6957 ways to override these when desired.
6958 - Delete result argument; this function shouldn't ever return.
6959 - Rename init_func argument to main_func, for less confusion.
6960 - Delete boot_cmd argument; main_func is more general.
6961 -Add 'closure' argument, to help people pass data to main_func
6962 without resorting to global variables.
6963 - Abort if reentered; don't bother returning an error code.
6964 - Call scm_init_standard_ports to set up the default/current
6965 standard ports; no need to pass them to scm_start_stack.
6966 - Remove code to evaluate the boot_cmd, and start the repl; let
6967 the user do something like that in main_func if they want.
6968 - Remove code to package up a return value; main_func can do any
6970 - Call exit (0), instead of returning.
6971 (scm_start_stack): Don't initialize the I/O ports here; that's
6972 weird. Delete in, out, err arguments. Move guts to
6973 scm_init_standard_ports, scm_stdio_to_port.
6974 (scm_init_standard_ports): New function, to set up current and
6975 default standard ports.
6976 (scm_start_stack, scm_restart_stack): Make these static.
6977 * init.h (scm_boot_guile): Adjust declaration.
6978 (scm_start_stack, scm_restart_stack): Remove externally
6979 visible declarations for these.
6980 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6982 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6983 written out several times in scm_start_stack.
6984 * fports.h: New declaration for the above.
6986 * feature.c (scm_set_program_arguments): New function.
6987 * feature.h: New declaration for the above.
6989 * ports.c: Formatting tweak.
6991 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6993 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6994 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6995 for obtaining the address of a car or cdr field. Motivation:
6996 &SCM_CXR make assumptions about the internal structure of the
6999 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
7000 Motivation: see SCM_CXRLOC.
7002 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
7003 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
7004 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
7005 Motivation: Safer use. Some other macros are defined in terms of
7006 these operations. If these are defined using the SCM_SETCXR
7007 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
7008 to inefficiency and an <e1> with side-effects could potentially
7009 break. Also, these particular operations are heavily utilized in
7010 the garbage collector. In unoptimized code there will be a
7013 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
7014 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
7015 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
7016 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
7017 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
7018 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
7019 vports.c: Cleaned up use of pairs: Don't make any special
7020 assumptions about the internal structure of selectors and
7021 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
7022 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
7023 (Among other things, this change makes it easier to build Guile
7024 with certain compilers which have problems with casted lvalues.)
7026 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7028 * stacks.c: Improve selection of relevant stack frames when making
7029 a stack object. Introduce one level of indirection in the stack
7030 object to make it possible to "narrow" to a certain region of the
7031 stack. This facilitates making use of more clever algorithms (not
7032 implemented) for selecting relevant frames and gives a cleaner
7033 design since selection of frames can be done independently of
7034 extraction of frames from the real stack.
7035 (scm_stack_id): Also take #t as argument which means look at
7038 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
7039 Turn n_tail into an integer directly representing current number
7040 of frames in stack. Add field tail.
7042 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
7044 * debug.c (scm_make_memoized): Made it available at scheme level.
7045 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
7046 SCM_NIMP before applying heavier predicates in argument checking.
7047 (scm_local_eval): Also take memoized object as argument.
7049 * backtrace.c (scm_display_error): Just a safety measure: Stacks
7050 aren't created with zero length, but should such a strange
7051 creature suddenly turn up...
7053 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
7055 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
7056 `del', for the sake of C++ compilers. (Patch applied by JimB.)
7058 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
7060 * variable.c (scm_make_variable): Make the name hint optional, as
7062 (anonymous_variable_sym): Renamed from variable_sym. All uses
7065 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7066 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7067 of scm_primitive_load_path was also changed to
7068 "primitive-load-path", from "%try-load-path". Callers changed.
7069 We'd like to respect the convention that a function named
7070 "try-mumble" should behave just like the function called "mumble",
7071 but return #f instead of signalling some error.
7072 * load.h: Rename prototypes.
7074 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7076 * print.c (make_print_state, grow_print_state), print.h: Modified
7077 the print state representation: Don't use a tail array for
7078 recording of circular references. Resizing of the print state
7079 structure invalidates the print state pointer. To avoid passing
7080 around an indirect print state reference to all printing
7081 functions, we instead let the print state reference a resizable
7084 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7086 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7087 Don't crash when passed an improper list terminated by a
7088 non-immediate value.
7090 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7092 Allocate data for structures on an eight-byte boundary, as
7093 required by the tagging system.
7094 * struct.c (alloc_struct): New function.
7095 (scm_make_struct, scm_make_vtable_vtable): Call it.
7096 * struct.h (scm_struct_n_extra_words): Bump to 3.
7097 (scm_struct_i_ptr): New "field".
7098 * gc.c (scm_gc_sweep): When we need to free the data, use the
7099 information stored by alloc_struct to find the beginning of the
7100 block allocated to the structure, so we can free it.
7102 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7104 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7107 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7108 (scm_debug_info): New member: id.
7110 * stacks.c: Stacks are now represented as structs; Stacks have an
7111 id given to them by `start-stack'.
7112 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7114 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7115 Changed stack representation.
7117 * debug.c (scm_procedure_name): Try procedure property `name' for
7118 compiled closures aswell.
7120 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7122 * eval.c: scm_i_name moved to gsubr.c
7123 (scm_m_define): Record names of all kinds of procedure
7124 objects. (Earlier, only closures were recorded.)
7126 * procprop.h: Added declaration of scm_i_name.
7128 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7129 (scm_make_gsubr): Record names of compiled closures.
7131 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7133 * debug.c, debug.h: Removed obsolete code.
7135 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7136 stacks.c: Renamed regs --> scm_contregs.
7138 * print.c (scm_free_print_state): Cleanup print state before
7139 returning it to pool. It is better to do it here than in
7140 scm_prin1 since scm_prin1 is called often.
7142 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7143 s_set_source_property_x): Check that first argument is a pair or a
7146 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7147 scm_i_line, scm_i_column and scm_i_breakpoint global.
7149 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7150 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7153 * debug.h: Added debug object smob declaration and macro
7156 * configure.in: Build with backtrace.o and stacks.o if debug
7159 * Makefile.in: Added entries for new files: backtrace.c,
7160 backtrace.h, stacks.c and stacks.h.
7162 * symbols.c (scm_sym2ovcell): Fixed documentation.
7164 * _scm.h (min, max): Added.
7166 * async.c: Moved `min' macro to _scm.h.
7168 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7169 SCM_BACKTRACE_INDENT.
7171 * eval.c: Added new debug options `maxdepth' and `indent'.
7173 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7175 * print.h: Added selector SCM_PRINT_STATE.
7177 * print.c: New functions: scm_make_print_state,
7178 scm_free_print_state.
7180 * print.h: Added declarations for scm_make_print_state,
7181 scm_free_print_state.
7183 * debug.c (scm_m_start_stack): New acro.
7185 * debug.h: Small cleanup.
7187 * init.c (scm_boot_guile_1): Moved scm_init_debug below
7190 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

7210 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
7211 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
7212 declare functions with prototypes. (Patch thanks to Marius
7215 More prototype-related changes from Marius Vollmer:
7216 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7217 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7218 * ports.h (ptobfuns): Added prototypes. This means some casting in
7220 * fports.c: Added casts for initializations, since the functions
7221 are defined to take FILE * as their stream argument, not SCM.
7222 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7223 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7224 to `char *str_data' to conform to prototype.
7226 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7228 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7230 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7232 * stime.c, stime.h: use SCM_P method.
7234 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7236 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7237 be given at least two arguments. Insist that lst's last element
7238 be a list, but don't make any requirements of its predecessors.
7240 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7242 * eval.c (scm_nconc2last): Revert last change; there seems to be
7243 other stuff going on here.
7245 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7247 * eval.c (scm_nconc2last): Make sure that each element of lst
7248 (which is a list of argument lists, except for the tail) is a
7249 proper list, i.e., finite and terminated by '().
7251 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7253 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7256 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7257 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7260 * vectors.c (scm_make_vector): Fill vectors with the undefined
7261 value, to help make Guile Scheme code more portable to other
7264 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7265 * symbols.h, tags.h: Doc fixes.
7267 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7269 * async.c (scm_take_signal): Doc fixes.
7271 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7273 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7274 want to subtract it from the modulus; we just want to leave it
7277 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7279 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7282 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7284 * throw.c (scm_catch_apply): Finished implementation of
7287 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7289 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7291 (scm_init_filesys): set "i/o-extensions" feature.
7294 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7296 * Makefile.in (root.o): Correct dependencies.
7298 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7300 * Makefile.in: Added dependency entry for root.o.
7302 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7303 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7305 * init.c (scm_start_stack): Set initial root continuation number
7308 * procs.c: New function: scm_thunk_p.
7310 * procs.h: Added declarations of scm_thunk_p.
7312 * root.c: Renamed `call-with-new-root' -->
7313 `call-with-dynamic-root'.
7314 (cwdr): Removed allocation of new root state. This should be done
7315 separately by use of scm_make_root.
7316 (scm_apply_with_dynamic_root): New function: Does what it
7317 sounds like. Needed when spawning threads.
7319 * root.h: Added member last_debug_frame to root state.
7320 Added #include "libguile/debug.h"
7322 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7323 arguments. The motivation is that code in root.c needs catch
7324 functionality, and we want to avoid code duplication.
7325 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7326 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7327 handlers that run without popping the stack into the dynwind
7330 * throw.h: Added prototypes for scm_catch_apply and
7333 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7335 * root.h (scm_root, scm_set_root): Decouple thread support details
7336 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7337 SCM_SET_THREAD_LOCAL_DATA.
7339 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7340 and tortoise scanning loop.
7342 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7344 * Makefile.in: Rebuild dependencies.
7346 * libguile.h: #include "libguile/print.h" before "smob.h", since
7347 the latter uses the print_state structure.
7349 * throw.c (scm_ithrow): Use the correct variable when checking to
7350 see if a given element of scm_dynwinds is a valid catch.
7352 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7353 structure, abort; don't just silently ignore the garbage.
7355 * _scm.h: #include "print.h" here, since it seems to be used just
7357 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7358 strports.c, unif.h: Don't #include "print.h".
7360 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7362 * feature.h (scm_loc_features): Removed external declaration.
7363 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7365 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7367 * feature.c (scm_init_feature): Added threads feature (needs to be
7368 initialized here, since features doesn't exist when
7369 scm_init_threads is called).
7371 * libguile.h: Added #include "libguile/../threads/threads.h".
7372 (This is a kludge to get thread support working. This should be
7375 * configure.in, acconfig.h: Added flags for thread support.
7377 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7380 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7381 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7384 * _scm.h: Added conditional #include "threads.h"
7386 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7387 SCM_THREADS_SWITCHING_CODE.
7389 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7390 allocate the basic dynamic root object.
7391 (scm_boot_guile): Added call to scm_init_root.
7393 * root.c, root.h: Added root smob.
7394 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7395 functions: Implements dynamic roots mostly according to spec in
7396 SCM manual. Main difference is that the second argument is a
7397 throw handler rather than an error "thunk".
7399 * root.h: Added declaration of scm_init_root.
7401 * root.c: Added #include "genio.h", #include "smob.h", #include
7402 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7404 (scm_init_root): Added #include "root.x".
7406 * throw.c: Added #include "stackchk.h"
7407 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7408 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7409 can be used in scm_call_with_new_root; Added reenabling of stack
7410 checking when catching a throw.
7412 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7414 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7416 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7417 element is not found, as per R4RS.
7419 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7421 * list.c: Doc fixes throughout.
7423 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7425 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7426 declare the char * to be const. Avoids a warning in rgx.c.
7428 * ports.h: spelling fix.
7430 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7433 * load.c (scm_sys_try_load_path): throw an error if file not found
7434 (like it says it in NEWS).
7436 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7438 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7439 PROPS slot to '(), not #f; it's an empty alist.
7441 * throw.h, throw.c: Use SCM_P instead of #if hair.
7443 Remove special support for uncaught throws; see throw.c for
7445 * throw.c (uncaught_throw): New function.
7446 (scm_ithrow): Call uncaught_throw if we don't find a throw
7447 target; don't mess with scm_bad_throw_vcell.
7448 (scm_bad_throw_vcell): Variable deleted.
7449 (scm_init_throw): Don't initialize it.
7451 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7454 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7456 * numbers.c (scm_istr2int): If the number is short (as most
7457 numbers are), just call scm_small_istr2int to deal with it.
7458 (scm_small_istr2int): New function, created by un-#ifdefing the
7459 non-bignum version of scm_istr2int and renaming it.
7461 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7463 * load.c (scm_sys_try_load): don't check whether value returned
7464 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7465 Change the Scheme name from %try-load to primitive-load.
7467 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7468 Can avoid passing a message, allowing it to be derived in the
7469 error handler (e.g., if we want to throw to the key both from
7472 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7474 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7475 references now have a new appearance which is more compact and
7476 also gives a clue about what the target of the reference is.
7477 By setting parameters in the print state, more fancy printing can
7478 be achieved. This is used by the (not yet commited) backtrace
7481 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7483 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7486 * print.c: Added #include "struct.h". Removed function
7489 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7490 scm_iprin1. Removed prototype for scm_prlist.
7492 * arbiters.c (prinarb),
7493 async.c (print_async),
7494 debug.c (prindebugobj, prinmemoized),
7495 eval.c (prinprom, prinmacro),
7496 filesys.c (scm_fd_print, scm_dir_print),
7498 mallocs.c (prinmalloc),
7499 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7500 smob.h (scm_smobfuns),
7501 srcprop.c (prinsrcprops),
7503 unif.c, unif.h (scm_raprin1, rapr1),
7504 variable.c (prin_var): Changed argument `int writing' to
7505 `scm_print_state *pstate'.
7507 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7508 that it will be called before scm_init_print.
7510 * print.c (scm_prin1): Print states are now allocated when calling
7511 scm_prin1 and then passed around to all printing functions as an
7512 argument. A cache `print_state_pool' enables reuse of print
7514 (scm_make_print_state): New function.
7515 (scm_iprin1): Adaption to print states.
7516 (scm_iprlist): An initial "hare and tortoise" scan brings down
7517 time complexity to O (depth * N). (Better time complexity will be
7518 achieved when the printing code is completely rewritten.)
7520 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7522 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7523 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7524 it gets done whether or not the cache variable has a value.
7526 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7528 Distinguish #f and ().
7529 * __scm.h: #undef SICP.
7530 * pairs.h (SCM_EOL): Delete this definition, equating it with
7532 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7533 the value it used to have. Doc fixes, too.
7535 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7537 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7538 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7539 Lord's implementation of structs, allowing for tail arrays as
7540 described in the manual. Also fixed some bugs. (Both the interface
7541 and the implementation should be improved.)
7543 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7545 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7546 People who whish to see the source can do `(print-enable 'source)'.
7547 Removed #ifdef DEBUG_EXTENSIONS.
7549 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7551 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7552 integer (assuming for now accepting an integer is a good thing).
7554 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7555 %S will be used instead for write'ing arguments.
7557 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7558 asserts. fix a few other asserts.
7559 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7560 scm_uniform_vector_ref, scm_array_set_x,
7561 scm_dimensions_to_unform_array): change args in
7562 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7563 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7564 scm_substring_fill_x): likewise.
7565 gsubr.c (scm_gsubr_apply): likewise.
7566 eval.c (SCM_APPLY): likewise.
7568 * eval.c (4 places): replace scm_everr with lgh_error or
7571 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7572 scm_memory_error): new procedures.
7573 scm_everr: deleted. can use scm_wta, dropping first two args.
7574 scm_error: convert NULL subr to SCM_BOOL_F.
7576 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7579 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7582 * error.c, error.h: new error keys: scm_arg_type_key,
7583 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7585 scm_wta: reimplement using lgh_error instead of scm_everr.
7587 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7589 * gdbint.c: scm_lread now has one more argument.
7591 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7592 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7593 loading source from non-file ports, which, e. g., happens when
7594 using the Emacs interface).
7596 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7599 * read.c: Added code for recording of positions of source code
7600 expressions; New functions: recsexpr, scm_lreadrecparen;
7601 _scm_make_srcprops --> scm_make_srcprops
7602 (scm_flush_ws): Removed updating of positions counters. This work
7603 is already done by scm_gen_getc
7605 * read.h: Added prototype for scm_lreadrecparen
7607 * print.c: Added #include "alist.h"
7609 * eval.c: Added #include "hash.h"
7611 * eq.c: Added #include "ramap.h"
7613 * options.c: Documentation fixes.
7615 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7616 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7617 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7618 --> scm_make_srcprops
7620 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7621 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7622 function calls in the definition of the whash access macros.
7624 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7626 * init.c (scm_boot_guile): Add level of indirection to
7627 scm_boot_guile_1() to ensure that stack base pointer is properly
7628 initialized. There was no guarantee that variable i was the
7629 highest/lowest variable on stack (i.e. the call frame of
7630 scm_boot_guile was not completely protected from gc).
7632 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7634 * ports.h (scm_port_table): put back file_name, it will be used to
7635 support debugging. Undo related changes in fports.c, ioext.c,
7638 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7640 * ports.h (scm_port_table): remove file_name member for now, it seems
7642 * fports.c (scm_open_file): don't set file_name in PTAB.
7643 (prinfport): don't use file_name in PTAB.
7644 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7645 * ports.c (scm_add_to_port_table): don't intialize file_name.
7646 (scm_port_file_name): remove for now.
7647 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7649 * fports.h (scm_mkfile): prototype deleted.
7650 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7652 * debug.c, unif.c: use scm_out_of_range instead of
7653 wta for range errors (ASSERT still needs work).
7655 * error.c, error.h (scm_out_of_range): new procedure.
7657 * error.c, error.h (scm_out_of_range_key): new key.
7659 * posix.c (scm_sync): #else was missing.
7661 * error.c, error.h: append _key to names scm_num_overflow and
7664 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7665 of consing an empty list.
7666 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7667 of macros, saves code and string space.
7668 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7669 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7670 lower case. Rename scm_syserror_m to scm_syserror_msg.
7671 error.h: prototypes for new procedures.
7673 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7675 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7677 * error.c, error.h: setup scm_num_overflow key.
7679 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7680 Remove definition of SCM_OVSCM_FLOW.
7682 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7684 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7685 explicit message and args.
7687 * error.c, error.h, __scm.h: change system_error_sym to
7690 * error.c (system_error_sym): remove leading %% from the Scheme name
7693 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7695 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7697 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7698 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7699 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7700 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7701 renamed. (These were introduced by unsupervised name
7704 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7706 * print.c: Added code for detection of circular references during
7707 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7708 a hook for printing of closures (accessible via print options).
7709 This leads to a split of calls to scm_iprin1 into two classes:
7710 elementary print operations (e. g. the code which prints a smob)
7711 still use scm_iprin1 while top level calls (like scm_display) use
7712 scm_prin1. scm_prin1 begins by clearing the data structure used
7713 to record reference information.
7715 * print.h: Added declarations of scm_prin1 and scm_prlist.
7717 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7719 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7721 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7723 * error.c (err_head): scm_iprin1 --> scm_prin1
7725 * debug.c: Adjusted header comment.
7729 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>

7733 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7735 * gdbint.c (gdb_read): Now possible to run during GC.
7736 (unmark_port, remark_port): New functions.
7738 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7740 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7741 of allocating a new string object. Also, increase size by
7742 the factor 2 instead of 1.5.
7744 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7746 * __scm.h (SCM_P): Corrected to run under traditional C.
7748 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7751 * async.c: Calls to scm_sysintern corrected.
7753 * async.h (scm_async_clock): Redundant declaration removed.
7755 * continuations.c (scm_dynthrow): Redundant declaration removed.
7757 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7758 Definition typos corrected.
7760 * debug.h: Missing declarations of functions in debug.c added
7763 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7764 Missing declarations to functions in eval.c added.
7766 * filesys.c: Possibly uninitialized variable rv.
7768 * gc.h (scm_object_addr, scm_unhash_name): Missing
7769 declarations of functions defined in gc.c added.
7771 * genio.c: Possible typos str_data -> wstr_data. ???
7773 * genio.c: Possibly unintended shadowing of local variable
7774 `int c' (gotos out of scope of inner `c'). ???
7776 * init.c: Uninitialized `SCM last' may be used.
7778 * ioext.h: (scm_sys_isatty_p): Typo.
7780 * list.h (scm_list_head): Missing prototype for function in
7783 * numbers.c (scm_two_doubles): Changed from extern to static
7784 (is used only within numbers.c).
7786 * numbers.h: Repeated declarations removed.
7788 * ports.h (scm_close_all_ports_except): Declaration for the
7789 function defined in ports.c added.
7791 * posix.h: Missing declarations added.
7793 * procs.h (scm_make_subr_opt): Missing declaration added.
7795 * socket.h (scm_sys_gethost): Missing declaration added.
7797 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7799 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7800 Missing declarations added.
7802 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7804 * struct.c: Uninitialized variable `SCM answer' may be used.
7806 * unif.c (l2ra): Declaration prototype.
7808 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7809 defined in ramap.c).
7811 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7812 Redundant declarations removed (they are in ramap.h).
7814 * variable.h (scm_make_udvariable,
7815 scm_make_undefined_variable): Declaration corrected to
7816 correspond variable.c.
7818 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7819 Missing declarations added.
7821 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7823 * Makefile.in (distclean): Don't forget to delete fd.h.
7825 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7827 * fd.h.in, tags.h: Trivial cleanups.
7829 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7830 marksweep.h just declared functions from gc.c.
7831 * gc.h, libguile.h: Don't #include "marksweep.h".
7832 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7833 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7834 dependencies updated.
7836 * libguile.h: Don't #include "files.h"; it's been deleted.
7838 * files.c (scm_sys_delete_file): Moved to filesys.c.
7839 File is now empty; deleted.
7841 * filesys.c: scm_sys_delete_file is now here. Remove
7842 #if's; they seem to rely on remnants of an old portability
7843 regimen. If the problems come up again, solve them properly,
7844 using autoconf. Specifically: Don't test M_SYSV, and #define
7845 remove to be unlink if it's #defined; don't use remove just
7846 because HAVE_STDC_HEADERS is #defined.
7847 * filesys.h: Add declarations for scm_sys_delete_file.
7848 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7849 files.o, files.h, files.c, and files.x.
7850 * init.c: Don't #include "files.h", and don't call scm_init_files.
7852 Use SCM_P instead of PROTO; the latter intrudes on the user's
7854 * params.h: Deleted; definition of SCM_P moved to...
7855 * __scm.h: ... here, where it replaces PROTO macro.
7856 * libguile.h, smob.h: Don't #include "params.h".
7857 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7858 smob.h: Fix prototypes accordingly.
7859 * Makefile.in: Update dependencies.
7860 (inner_h_files): Remove params.h.
7862 * gc.c: #include "gc.h"; every module should include its header,
7863 to let the compiler cross-check the declarations against the
7866 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7867 simpos.h: #include "libguile/__scm.h".
7869 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7871 * init.c: Don't forget to #include smob.h and init.h.
7872 * Makefile.in: Dependencies updated.
7874 * smob.h: Use PROTO instead of #if __STDC__.
7876 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7878 * __scm.h: Doc fixes.
7880 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7881 <angles>; this allows `make depends' to work properly.
7883 * libguile.h: #include smob.h and pairs.h before the others; they
7884 define typedefs used by other headers.
7886 C files should #include only the header files they need, not
7887 libguile.h (which #includes all the header files); the pointless
7888 recompilation was wasting my time.
7889 * Makefile.in (all .o dependency lists): Regenerated.
7890 * libguile.h: Don't try to get a definition for size_t here...
7891 * __scm.h: Do it here.
7892 * _scm.h: Since this is the internal libguile header, put things
7893 here that all (or a majority) of the libguile files will want.
7894 Don't #include <libguile.h> here; that generates dependencies on
7895 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7896 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7897 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

7993 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
7994 * weaks.c: Get "weaks.h".
7996 * stackchk.h: #include "libguile/debug.h",
7998 * print.h, read.h: #include "options.h", since everyone who uses
7999 either of these files will need that.
8001 * smob.h: #include "ports.h", "genio.h", and "print.h", since
8002 anyone who uses this file will need them to define the smob
8003 printing functions. Also, get markers.h, since people will need
8004 to #define the mark functions.
8006 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
8007 * ports.h: ... to here.
8009 * ports.h (scm_port_table_size): Explicitly give type as 'int';
8010 don't rely on archaic C default type rules.
8012 * fports.h: #include "libguile/ports.h", since you need that in
8013 order to parse this.
8015 * genio.h: #include "libguile/print.h", because you need that to
8016 parse this; don't bother #including "ports.h", since print.h gets
8019 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
8021 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
8022 this; it's now a reference to an element of *scm_root.
8024 * debug.h: Don't #include "options.h"; the compiler won't be able
8025 to find that once the headers are installed; instead, #include
8026 "libguile/options.h".
8027 * gc.h: Same, with marksweep.h.
8028 * mbstrings.h: Same, with symbols.h.
8029 * scmhob.h: Same, with _scm.h.
8030 * smob.h: Same, with params.h.
8032 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
8033 C files; there's no need for this, and it forces recompilations
8036 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
8038 * error.c (scm_error): declare scm_error_callback.
8040 * error.h: prototype for scm_error_callback.
8042 * __scm.h: define lgh_error.
8043 (SCM_SYSERROR): redefine using lgh_error.
8045 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
8047 * error.c (scm_error): new procedure.
8049 * error.h: prototype for scm_error.
8051 * Makefile.in (install): install scmconfig.h from the current
8052 directory, not $(srcdir).
8054 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8056 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8057 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8058 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
8059 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
8060 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
8061 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8062 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8063 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8064 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8065 vports.h, weaks.h: #include "libguile/__scm.h", not
8066 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
8067 dependencies are within libguile properly.
8069 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8071 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8072 when scmconfig.h doesn't exist.
8074 * load.c (scm_sys_try_load): Correct spelling.
8076 * feature.c (scm_loc_features): Make this static.
8078 * Makefile.in (libpath.h): Omit trailing slash from path. We
8079 shouldn't require it of users, so why put it here?
8081 Move code to initialize and search %load-path from ice-9 to C
8082 code, so we can use the load-path to find the ice-9 boot code;
8083 this makes it easier to run Guile without installing it. See
8084 corresponding changes in guile/Makefile.in.
8085 * feature.c: Move stuff concerned with the load path to load.c.
8086 (scm_compiled_library_path): Deleted.
8087 Don't #include libpath.h here.
8088 * feature.h: Don't mention scm_compiled_library_path.
8089 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8090 <sys/stat.h>, and <unistd.h> (if present).
8091 (R_OK): #define if the system hasn't deigned to.
8092 (scm_loc_load_path): New variable.
8093 (scm_init_load_path, scm_sys_search_load_path,
8094 scm_sys_try_load_path): New functions.
8095 (scm_init_load): Initialize scm_loc_load_path to point to the
8096 value cell of the Scheme %load-path variable.
8097 * load.h: Add declarations for scm_sys_search_load_path,
8098 scm_sys_try_load_path.
8099 * init.c: Call scm_init_load_path.
8100 * Makefile.in (feature.o, load.o): Dependencies updated.
8102 * load.c, load.h: Rewrite using PROTO macro.
8104 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8106 * gc.c (scm_cellp): New function: C predicate to determine if an
8107 SCM value can be regarded as a pointer to a cell on the heap.
8109 * gc.h: Added declaration of scm_cellp.
8111 * gdb_interface.h: New file: The GDB interface header from the GDB
8114 * gdbint.c: New file: GDB interface.
8116 * gdbint.h: New file: GDB interface.
8118 * libguile.h: Added #include <libguile/gdbint.h>.
8120 * init.c (scm_boot_guile): Added scm_init_gdbint.
8122 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8123 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8124 found if object files and source are kept separate).
8126 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8128 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8130 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8132 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8133 TK_SRC_DIR; they're not relevant any more.
8135 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8136 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8138 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8140 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8141 search path, so we can find the <libguile/MUMBLE.h> headers.
8143 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8145 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8146 implicit in the .c.o rule.
8147 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8150 Put the library path in a header file, instead of passing it on
8151 the command line in every compilation.
8152 * Makefile.in (libpath.h): New target.
8153 (feature.o): Depend on libpath.h.
8154 (clean): Delete libpath.h.
8155 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8156 * feature.c: ... #include "libpath.h" here.
8157 * .cvsignore: Ignore libpath.h.
8159 Don't install the unwashed masses of Guile header files in the
8160 main #include path; put most of them in a subdirectory called
8161 'libguile'. This avoids naming conflicts between Guile header
8162 files and system header files (of which there were a few).
8163 * Makefile.in (pkgincludedir): Deleted.
8164 (innerincludedir): New variable; this and $(includedir) are enough.
8165 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8166 (installed_h_files): Divide this up. Now this variable lists
8167 those header files which should go into $(includedir) (i.e. appear
8168 directly in the #include path), and ...
8169 (inner_h_files): ... this new variable says which files appear in
8170 a subdirectory, and are referred to as <libguile/mumble.h>.
8171 (h_files): List them both.
8172 (install): Create innerincludedir, not pkgincludedir. Put
8173 the installed_h_files and inner_h_files in their proper places.
8174 (uninstall): Corresponding changes.
8175 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8176 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8177 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8178 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8179 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8180 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8181 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8182 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8183 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8184 vports.h, weaks.h: Find __scm.h in its new location.
8185 * __scm.h: Find scmconfig.h and tags.h in their new locations
8186 (they're both "inner" files).
8188 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8190 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8192 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8194 * posix.c: Doc fixes.
8196 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8198 * socket.c: Don't include a prototype for inet_aton; just use a
8199 K&R style declaration, to avoid warnings but minimize the chance
8200 of conflicts with the system.
8202 On NextStep, <utime.h> doesn't define struct utime, unless we
8203 #define _POSIX_SOURCE before #including it.
8204 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8205 * acconfig.h: New comment text for above CPP symbol.
8206 * configure.in: Call it.
8207 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8209 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8211 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8212 testing for __EMX__.
8214 * posix.c: #include <libc.h>, if it exists.
8216 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8217 don't even know if the latter exists.
8219 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8220 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8221 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8223 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8225 (scm_init_posix): Use them when initializing the Scheme constants
8228 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8230 * Makefile.in (libdir, includedir, bindir): Use the
8231 autoconf-supplied values, instead of deriving them ourselves.
8232 (pkgincludedir, datadir, pkgdatadir): New variables.
8233 (install, uninstall): Put the header files in a special
8234 subdirectory, not in the main search path.
8236 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8237 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8239 * Makefile.in (IMPLPATH): Deleted; never used.
8241 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8242 on the Tcl/Tk source any more.
8243 (INCLUDE_CFLAGS): Remove references to the above.
8245 * Makefile.in (version.o): Corrected dependencies.
8247 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8249 * libguile.h: #include "version.h"
8251 * init.c (scm_boot_guile): Call scm_init_version.
8252 * gscm.c (gscm_run_scm): Call scm_init_version.
8254 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8255 GUILE_VERSION): AC_DEFINE these.
8256 (acconfig.h): #undef the above symbols.
8258 * Makefile.in (libobjs): Add version.o.
8259 (installed_h_files): Add version.h.
8260 (c_files): Add version.c.
8261 (gen_c_files): Add version.x.
8262 (version.o): New rule.
8263 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8264 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

8280 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8282 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8283 array; use it appropriately. Since GCC is quite happy to
8284 subscript functions, it never warned us about this; we should use
8285 -Wpointer-arith in the future. I guess we never tested
8288 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8290 * socket.c: Doc and copyright fixes.
8292 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8294 * debug.c: Fixed and improved gdb support.
8296 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8298 * socket.c: Added declaration of inet_aton to avoid compiler
8299 warning. (Hope this solution is correct.)
8301 * stime.c: Added declaration of ftime. (This is missing in
8304 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8306 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8308 * Makefile.in (c_files): add strerror.c.
8310 * strerror.c: new file from Emacs' sysdep.c.
8311 maybe configure should also check for sys_errlist.
8313 * configure.in (AC_REPLACE_FUNCS): add strerror.
8315 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8317 * debug.c (scm_init_debug): Added initialization for
8318 scm_evaluator_traps.
8320 * debug.h, debug.c: Various name changes.
8321 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8322 "debug-options-interface". See commentary in options.c.
8324 * options.h, options.c: Options now have documentation strings.
8325 Also added a long explanatory commentary.
8327 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8330 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8331 last_debug_info_frame is now updated in all cases.
8333 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8336 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8338 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8339 Added option STACK_CHECKING.
8341 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8343 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8345 * __scm.h: Removed symbols for debugging support.
8347 * acconfig.h: Added symbols for debugging support.
8349 * configure.in: Added user option for debugging support.
8350 --enable-debug will include the debugging code into libguile.a.
8352 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8353 scm_relocate_chunk_to_heap.
8355 * debug.c: New file: low-level debugging support. It also
8356 includes support for debugging with gdb. (The extensions to gdb
8357 are written by Per Bothner at Cygnus.)
8359 * debug.h: New file: low-level debugging support.
8361 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8362 argument pairs. Extensive modifications to the debugging
8363 evaluator. Added "SECTION:" commentaries to clarify what happens
8364 when, during double compilation. Renamed EVALIMP --> EVALIM.
8365 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8366 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8367 the beginning of the file. New procedure: scm_unmemocopy.
8368 Added some global state variables needed by the debugging
8369 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8370 check_entry, check_apply, check_exit, debug_options and
8371 evaluator_traps. New acro: undefine.
8373 * eval.h: Renamed EVAL --> XEVAL.
8375 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8376 --> scm_make_weak_key_hash_table.
8378 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8379 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8381 * libguile.h: Conditionally include debug.h
8383 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8384 scm_object_properties shouldn't return handle. `handle' now gets
8385 initialized in scm_set_object_properties_x. scm_object_properties
8386 doesn't any longer create an entry in scm_object_whash.
8388 * options.c: New file: handling of run time options.
8390 * options.h: New file: handling of run time options.
8392 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
8394 * print.c: New procedure: scm_print_options
8396 * print.h: Defines for print options.
8398 * read.c: New procedure: scm_read_options
8400 * read.h: Defines for reader options.
8402 * root.h: Added scm_source_whash among scm_sys_protects.
8404 * srcprop.c: New file: source properties.
8406 * srcprop.h: New file: source properties.
8408 * throw.c (jbsmob): Jump buffers are now correctly allocated.
8409 (Bug found by A. Green.)
8411 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8413 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8415 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8417 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8419 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8420 and should be called by the final client.
8422 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8424 * gc.h: Use the PROTO macro when declaring functions.
8425 * gc.c: Use the PROTO macro when declaring static functions.
8426 Remove the CPP hair around function definitions.
8428 * gc.c (scm_init_storage): Initialize scm_asyncs.
8430 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8431 preprocessor symbol; "__scm.h" is where it might get #defined.
8432 * __scm.h: Similar: #include <scmconfig.h> before testing
8435 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8437 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8439 * init.c (scm_boot_guile): Add init_func argument; call
8440 (*init_func) instead of calling scm_appinit; it's ucky to
8441 hard-code names for the user's procedures.
8442 * init.h (scm_boot_guile): Adjust declaration.
8444 * __scm.h (PROTO): New macro, for declaring functions with
8447 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8448 eliminate all the __STDC__ conditionals.
8449 (scm_boot_guile): Add declaration.
8450 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8451 Remove __STDC__ conditionals around function definitions; the
8452 declarations in init.h will provide the same information, more
8455 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8456 complain about it in the error message; the error message is
8457 adequate without that note, and there's nothing the user can do
8460 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8462 * Makefile.in (ancillary): Drop def.sed.
8464 * posix.c (scm_init_posix): Use numeric values, rather than
8465 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8466 F_OK. The symbols aren't available on some systems, and I'm
8467 pretty sure their values are fixed by common widespread practice.
8468 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8470 More functions unavailable on some systems.
8471 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8472 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8474 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8475 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8476 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8477 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8478 stub that signals an error as the #else.
8480 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8482 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8484 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8486 * unif.c: include ramap.h.
8488 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8490 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8492 * ports.c: include sys/ioctl.h.
8494 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8496 * configure.in: check for sys/ioctl.h.
8498 * ports.c: include <malloc.h> not "malloc.h".
8500 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8502 * fports.c: remove ttyname and tmpnam declarations.
8504 * posix.c: fewer ttyname declarations.
8506 * fports.c: include <string.h> not "string.h".
8508 * init.c, ioext.c: include string.h and unistd.h.
8510 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8512 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8513 genio.c, simpos.c, vports.c: include string.h.
8515 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8517 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8519 (scm_addr_buffer_size): change type from scm_sizet to int.
8520 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8521 from scm_sizet to int.
8523 * error.c: include unistd.h.
8525 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8528 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8530 * __scm.hd, def.sed: deleted.
8532 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8534 Changes for NeXT, suggested by Robert Brown.
8535 * configure.in: Call AC_TYPE_MODE_T.
8536 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8537 NeXT. Put header file list in alphabetical order.
8538 * configure, scmconfig.h.in: Regenerated.
8539 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8541 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8544 * acconfig.h: New file, providing documentation for the CPP
8545 symbols defined in configure.in
8546 * acconfig-1.5.h: Removed; superceded by the above.
8548 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8550 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8552 * fports.c (scm_open_file): don't return #f, throw error.
8554 * ioext.c (fileno): renamed from %fileno.
8555 (soft-fileno): deleted.
8557 * ports.c (scm_port_revealed): don't need to check for -1 from
8559 (scm_set_port_revealed_x): return unspecified, not #f.
8561 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8563 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8565 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8567 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8569 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8571 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8572 This is necessary on Ultrix, and doesn't hurt portability.
8574 * Makefile.in (dist-dir): New target, implementing a new dist system.
8575 (installed_h_files): Put in alphabetical order.
8576 Remove duplicate entries for markers.h and unif.h.
8577 (c_files): Remove duplicate entries for markers.c.
8578 (ancillary): Renamed from anillery; all uses changed. Remove
8579 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8580 Remove all the ../doc/* files; doc/Makefile.in handles that.
8582 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8584 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8585 every if must have an else, or else the whole command has a
8586 non-zero exit code whenever the if's condition is false.
8588 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8590 * posix.c: include string.h.
8592 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8594 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8597 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8598 Remove leading % from scheme names.
8599 Do not return error values, call SCM_SYSERROR or similar.
8601 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8603 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8605 * struct.c (scm_init_struct): new file.
8607 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8609 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8610 (scm_list_head): added list-head for rapidly chopping argument
8611 lists off of longer lists (and similar).
8613 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
8615 * objprop.c (scm_object_property): assq the cdr of the whash
8616 handle for obj, not the handle itself.
8618 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8620 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8621 weak hash tables last of all marking to avoid an obscure gc bug.
8622 WARNING: circular lists stored in a weak hash table will hose us.
8624 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8626 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8627 new functions similar to scm_substring_move_left_x and
8628 scm_substring_move_right_x.
8630 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8632 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8635 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8637 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8639 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8641 * strports.c (scm_strprint_obj): convenience function. C for
8642 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8644 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8645 removed to a separate library
8647 * init.c (scm_boot_guile): copied from guile-tcl.c.
8648 Initialization specific to tcl interpreters removed.
8650 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8652 * ports.c (scm_ports_prehistory): size malloced here doesn't
8653 matter so long as it is non-0 (got rid of "* 4").
8655 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8657 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8658 since its definition was bogus).
8660 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8662 * mallocs.[ch]: back again (for rx at least).
8664 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8666 * ports.c: removed functions relating to the mapping between ports
8667 and descriptors. (That stuff is unix-specific and should be collected
8668 in a separate library).
8670 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8671 (Tom Mckay@avanticorp.com)
8673 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8675 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8676 handled correctly (SCM_FREEP was applied to them) -- test for
8677 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
8678 being overwritten with #f. (brown@grettir.bibliotech.com)
8680 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
8682 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
8683 for a specific symbol or for all symbols.
8685 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
8687 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
8688 keys and weak values confused).
8690 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
8692 * list.c (scm_last_pair): map '()=>'()
8694 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
8696 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
8697 Generalized assoc and hash-table functions.
8698 Factored pairs.c into multiple files.
8700 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
8702 * gscm.c (gscm_run_scm): got rid of objprop.
8704 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
8706 * genio.c (scm_getc):
8707 NOTE: fgetc may not be interruptable.
8709 * procprop.c (scm_stand_in_scm_proc):
8710 NOTE: don't use a alist here.
8711 (scm_set_procedure_properties_x): fix type checking throughout this file.
8713 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
8715 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
8716 after freeing part of the port table.
8718 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
8720 * strports.c (scm_mkstrport):
8721 * vports.c (scm_make_soft_port): allocate a port table entry
8722 (possibly triggering gc) before setting the tag of the corresponding
8725 * pairs.c (scm_delq_x): never throw an error.
8727 * vectors.c (scm_make_vector): made the default vector fill argument
8728 into '() (much more useful than the previous value, "#unspecified")
8730 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
8732 * ports.c (scm_add_to_port_table): Added fields
8733 to port table entries: file_name, line_num, col.
8734 Update these in open_file, gen_getc and gen_ungetc.
8735 Added procedures to access those fields.
8737 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
8739 * procs.c (scm_make_subr_opt): new entry point for making
8742 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
8744 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
8746 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
8748 * numbers.c (scm_exact_p): This function no longer
8749 implements "integer?".
8751 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
8753 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
8754 (scm_gc_stats): return an assoc of useful data. Replaces "room"
8755 and the stats reporting formerlly built into repl.
8757 * repl.[ch]: removed.
8758 GC statistics keeping moved to gc.c.
8759 Other statistics keeping can be done from Scheme.
8760 REPLS are now written in Scheme.
8762 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
8764 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
8765 conservatively marked objects).
8767 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
8769 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
8771 * feature.c (scm_compiled_library_path): moved here from repl.c.
8772 This file is for stuff relating specifically to Scheme libraries
8775 * eval.c (scm_m_define): don't give warning about redefinition, don't
8778 NOTE: this should throw a resumable exception with parameters --
8779 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?

8845 initialization to fix a race condition.
8847 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

8871 set the multi_byte flag correctly in symbols. This is wrong.
8872 intern_obbary_soft and msymbolize should take an extra parameter.
8873 Also, weird multibyte symbols don't print correctly.
8874 The weird symbol syntax is also a bit bogus (emacs doesn't quite
