1 1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
3 * version.c (scm_libguile_config_stamp): Deleted. See
4 corresponding change to ../ice-9/boot-9.scm.
5 * version.h: Delete prototype.
6 * Makefile.in: Regenerated.
8 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
10 * filesys.c (scm_directory_p): new procedure "directory?" Returns
11 a boolean indicating whether its argument is a directory
12 port as returned by opendir (thanks to Dirk Herrmann for the
15 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
17 * backtrace.c (display_frame_expr): Don't print a newline.
18 (display_frame): Print the newline here instead.
20 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
22 * procs.c (scm_setter): Signal WTA if handed an entity or operator
25 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
26 primitives. (Thanks to Greg Badros);
27 (scm_hook_to_list): New primitive; Hooks are now smobs.
29 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
31 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
32 of #f for the 10th vector element to avoid an exception
33 seen by Bernard Urban.
34 (scm_mktime): unneeded ASSERT removed.
36 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
38 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
41 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
43 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
45 * numbers.c: Converted comparison operations to dispatch on
46 generic if args don't match.
48 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
50 1999-09-06 James Blandy <jimb@mule.m17n.org>
52 * guile-snarf.c: Deleted. Snarfing should respect CPP
53 conditionals, so it needs to actually run CPP. Bleah.
55 1999-09-05 James Blandy <jimb@mule.m17n.org>
57 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
58 * guile-snarf.in: Be sure to exit with an error if CPP does.
59 * Makefile.am (.c.x): Delete the .x file and exit with an error
60 status if guile-snarf exits with an error status.
61 * Makefile.in: Regenerated.
63 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
64 scm_makekey, which doesn't exist any more. Guess nobody's using
67 * guile-snarf.c: New implementation of guile-snarf, meant to be
68 more robust than the shell script. I think it's complete, but I
69 haven't tested it at all, and I haven't changed the build process
70 to actually use it. We should compare its output against that of
71 the existing shell script, for all source files.
73 * guile-snarf.c (parse_args): Abort if we haven't handled some
76 1999-09-03 James Blandy <jimb@mule.m17n.org>
78 * load.c (scm_search_path): If the filename has any extension at
79 all, ignore the entire list of extensions. Also, don't check whether
80 the file is accessible. If the file exists, accessible or not, we
81 should return it. Inaccessible files should cause an error later.
82 (Thanks to Keisuke Nishida for the suggestions.)
84 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
86 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
87 atexit not available. (sunos4.1.4 needs it.)
89 1999-09-01 James Blandy <jimb@mule.m17n.org>
91 I take it all back --- bcopy does handle overlapping source and
92 destination areas correctly. At least on every system I could
93 find. But it is better to use AC_REPLACE_FUNCS than to introduce
95 * memmove.c: New file, implementing memmove in terms of bcopy.
96 * scmconfig.h.in: Regenerated.
98 Allocators should use the `void *' type for generic pointers.
99 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
100 argument and return types.
101 * gc.h: Corresponding changes to prototypes.
104 1999-08-31 James Blandy <jimb@mule.m17n.org>
106 * numbers.c (scm_init_numbers): Claim to support the `complex'
107 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
109 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
110 find (ice-9 boot-9) when Guile was compiled in a separate
111 directory from the source. (Thanks to Rodney Brown.)
112 * Makefile.in: Regenerated.
114 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
115 table lengths by the size of a single element when growing the
116 table. (Thanks to Bill Schottstaedt.)
118 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
120 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
121 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
122 since that cuts down the time for type dispatch by 50%.
124 1999-08-30 James Blandy <jimb@mule.m17n.org>
126 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
127 not a correct substitute for memmove, because it doesn't handle
128 overlapping source and destination areas on many platforms.
129 Overlaps are the primary reason to use memmove in the first place.
130 * ports.c (scm_ungetc): Same.
131 * strop.c (scm_substring_move_x): Same.
133 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
135 * gc.c (scm_init_storage): Skip registration of cleanup on systems
136 which lack atexit. (Is it important that cleanup is made
137 properly? Maybe we should replace all `exit' with `scm_exit' and
140 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
141 scm_struct_free_standard, scm_struct_free_entity): Declared to
142 return scm_sizet instead of size_t.
144 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
145 there on sunos4.1.4.)
147 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
149 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
150 Account for the case when second argument is unbound.
152 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
153 (Thanks to Karoly Lorentey.)
155 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
156 isn't present. (Thanks to Suzuki Toshiya.)
158 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
161 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
164 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
165 Bernard Urban and Ian Grant.)
167 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
168 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
169 change in the representation of entities and operators.)
171 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
173 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
174 don't allocate zero bytes (thanks to Bill Schottstaedt).
176 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
178 * procs.c (scm_setter): Converted to use generic dispatch.
180 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
183 * load.c (scm_search_path): Don't try extensions which already are
184 present at the end of the filename.
185 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
187 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
189 Cleanup and simplification of generic method dispatch.
190 Also, the quadruple representation of entity and operator
191 procedures has been replaced with single.
193 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
195 * print.c (scm_isymnames): Removed #@hash-dispatch.
197 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
198 from eval.c; Support 0 arity methods.
199 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
200 (scm_apply_generic_env): Removed.
201 Replaced slots proc0-3 with procedure.
203 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
204 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
205 SCM_OPERATOR_PROCEDURE.
206 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
207 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
209 * struct.c, struct.h: Replace 4 procedure slots with one.
210 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
212 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
215 * eval.c (scm_sym_args): Removed.
216 (SCM_CEVAL): Simplified entity application.
217 Moved dispatch code to objects.c.
219 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
221 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
223 * sort.c (closureless): Use scm_eval_body.
225 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
226 with a symbol as last form was first called normally and then via
227 `map' or some other mechanism using primitive apply, an ILOC was
230 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
232 This change extends the representation of primitive procedures
233 with more data fields, e.g. a place for documentation and true
234 procedure properties.
236 * procs.c, procs.h (scm_subr_entry): New type: Stores data
237 associated with subrs.
238 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
239 SCM_SUBR_DOC): New macros.
240 (scm_subr_table): New variable.
241 (scm_mark_subr_table): New function.
243 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
245 * gc.c (scm_gc_mark): Don't mark subr names here.
246 (scm_igc): Call scm_mark_subr_table.
249 This change implements a scheme for letting a generic work as a
250 shadow for a primitive procedure. If the primitive procedure
251 can't dispatch on its arguments, control is left over to the
252 generic. Normal wrong type arg errors will be generated until the
253 user has hung the first method on the primitive.
255 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
257 * procs.c, procs.h (scm_subr_p): New function (used internally).
259 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
261 * objects.c, objects.h (scm_primitive_generic): New class.
263 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
265 * print.c (scm_iprin1): Print primitive-generics.
267 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
268 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
270 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
271 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
272 primitives). NOTE: This means that it is now *required* to use
273 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
274 obscured representation that will be removed in the future anyway,
275 so backward compatibility is no problem here).
277 * numbers.c: Converted most numeric primitives (all but bit
278 comparison operations and bit operations) to dispatch on generic
282 Better support for applying generic functions.
284 * eval.c, eval.h (scm_eval_body): New function.
286 * objects.c (scm_call_generic_0, scm_call_generic_1,
287 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
291 Optimization of the generic function dispatch mechanism.
293 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
294 called scm_memoize_method instead of doing a second lookup.
296 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
301 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
302 scm_sysintern so that the binding connected with the subr name
303 isn't cleared when we give set = 0.
306 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
308 More transparent handling of ports with print states.
310 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
311 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
312 instead of a pair of a port and a print state. We'll need to cons
313 once extra in scm_printer_apply but the type system will be
314 cleaner, it will mix better with GOOPS, and, it will be even more
315 transparent to the user.
317 * print.c (scm_get_print_state): New procedure: Given an output
318 port, return the print state associated to it in the current print
319 chain, if one exists;
320 (scm_port_with_print_state): New procedure: Associate a
321 print-state with a port.
322 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
323 (scm_printer_apply): Wrap port and pstate as a smob;
324 (print_state_printer): Removed.
326 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
328 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
331 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
332 testing (otherwise the port-print-state trick won't be transparent
333 to the user; one example where this caused problems was in the
334 (ice-9 format) module).
336 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
338 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
339 SCM_UNSPECIFIED instead of the set value.
341 1999-08-20 James Blandy <jimb@mule.m17n.org>
343 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
345 * ports.h (enum scm_port_rw_active): New enum, containing
346 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
347 zero). The debugger knows about enums, but doesn't know about
349 (typedef scm_port): Declare rw_active member to be an enum
351 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
353 * ports.c (scm_add_to_port_table): Same.
354 * strports.c (st_flush, st_end_input): Same.
356 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
357 scm_must_realloc, and scm_done_malloc as appropriate.
359 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
361 * sort.c (quicksort): Added condition to protect the algorithm
362 from crashing the interpreter if the less predicate is buggy.
364 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
366 * fports.c (fport_write): fix line-buffering mode again.
367 (scm_open_file): recognise 'l' for line-buffering.
368 (scm_setvbuf): recognise _IOLBF for line-buffering.
370 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
372 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
375 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
378 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
380 * fports.c (fport_write): use memcpy instead of strncpy, in case
381 the data contains NUL.
383 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
385 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
387 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
388 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
389 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
390 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
391 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
392 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
393 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
394 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
395 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
396 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
397 scm_sym_ as prefix for symbols.
399 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
401 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
402 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
403 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
404 scm_sym_atcall_cc): Made global.
406 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
408 * eval.c (scm_sym_args): Made global.
410 * objects.c (scm_set_object_procedure_x): Disallow setting of
411 procedures for pure generic functions.
413 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
415 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
416 Scheme name from lseek to seek, but lseek was added recently so
417 it shouldn't be a big problem.
418 * ports.c, gdbint.c, ioext.c: changed callers.
420 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
422 * fports.c (fport_input_waiting): if select is used, return 1
423 instead of whatever FD_ISSET expands to. maybe it will be useful
424 to interpret the value from the input_waiting ptob procedure as a
425 lower bound on the number of bytes available.
427 * Mikael asked for a few names to be changed...
429 * ports.c (scm_make_port_type): take the write procedure as the
430 second argument instead of the flush procedure.
431 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
432 fflush -> flush, read_flush -> end_input, fclose -> close,
433 fill_buffer -> fill_input, ftruncate -> truncate,
434 input_waiting_p -> input_waiting.
436 * ports.c (end_input_void_port): was read_flush_void_port.
437 (scm_set_port_end_input): was scm_set_port_flush_input.
438 (scm_set_port_flush): was scm_set_port_write.
439 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
440 (scm_end_input): was scm_read_flush.
441 (scm_fill_input): was scm_fill_buffer.
442 (scm_flush): was scm_fflush.
443 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
444 (fport_end_input): was local_read_flush.
445 (fport_flush): was local_fflush.
446 (fport_close): was local_fclose.
447 (fport_truncate): was local_ftruncate.
448 (fport_seek): was local_seek.
449 (fport_free): was local_free.
450 (fport_fill_input): was fport_fill_buffer.
451 * strports.c (st_end_input): was st_read_flush.
452 (st_truncate): was st_ftruncate.
453 * vports.c: (sf_flush): was sfflush.
454 (sf_close): was sfclose.
455 (sf_fill_input): was sf_fill_buffer.
457 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
460 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
462 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
463 forms now contain the expressions to be dispatched upon instead of
464 depending on a surrounding lambda or let; Generic function
465 dispatch has been optimized; `apply' on a generic function now
466 works a little bit strangely. It uses a trick so that the type
467 dispatch code in SCM_CEVAL can be reused.
469 * objects.h, objects.c (scm_apply_generic_env): Added (used by
471 (scm_operator_p): Added.
472 (scm_sym_atdispatch): Added.
473 (scm_set_object_procedure_x): Modified to handle the new style
475 (scm_object_procedures): New debugging procedure.
477 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
479 * eval.c, eval.h (scm_sym_args): Added.
481 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
483 * feature.c, feature.h (scm_c_run_hook): Added.
485 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
486 cdrxnoap and loopnoap instead of begin and loop.
488 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
490 * ports.c (scm_putc, scm_puts),
491 * unif.c (scm_uniform_array_write): use scm_lfwrite.
492 * ports.c (scm_putc): change type of first argument from int to char.
494 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
496 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
497 SCM_IM_HASH_DISPATCH.
499 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
500 (scm_si_redfined, scm_si_hashsets): Moved.
502 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
503 flag which combines type and status info so that the class
504 redefinition protocol has zero cost during normal execution.
506 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
508 * ports.h (scm_ptob_descriptor): include a write procedure again.
509 it's more efficient for unbuffered fports (e.g., sockets.)
511 * ports.c (scm_puts): use ptob->write.
512 * vports.c (scm_make_sfptob): set write proc in ptob.
513 * strports.c (scm_make_stptob): set write proc in ptob.
514 * ports.c (write_void_port): new procedure.
515 * vports.c (sf_write): new procedure.
516 * ports.c (scm_lfwrite): use ptob->write.
517 * strports.c (st_write): new procedure.
518 * fports.c (fport_write): new procedure.
519 (scm_make_fptob): set write in ptob to fport_write.
520 * ports.h: prototype for scm_set_port_write.
521 * ports.c (scm_make_port_type): initialise ptob write procedure.
522 (scm_set_port_write): new proc.
524 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
526 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
527 until we've verified that it is actually a port. (Thanks to
530 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
532 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
533 code, particularly an unnecessary test (len != size, where len ==
534 size). (Was this leftovers from debugging code, or have I missed
537 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
538 size. (Thanks to James Dean Palmer.)
540 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
541 (Thanks to Lorentey Karoly.)
543 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
545 * eval.c (scm_m_expand_body): Use scm_cons_source.
547 * struct.c (scm_print_struct): Use vtable name.
549 * print.c (scm_init_print): Set name of print state type.
551 * stacks.c (scm_init_stacks): Set name of stack type.
553 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
555 * eval.c (SCM_CEVAL): Removed old implementation of internal
558 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
560 * debug.c, debug.h (scm_reverse_lookup): Added.
561 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
562 internal procedure definitions; Don't use scm_i_inner_name.
564 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
567 * eval.h: Added prototypes for multi language support functions.
569 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
570 improper lists in the low-level representation, since that will
571 cause a begin to be prepended at macro expansion.
573 * eval.c (scm_cons_source): Version of cons which copies source
574 properties from an existing cell.
575 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
577 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
578 procedure source before calling scm_unmemocopy instead of faking
581 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
583 Ported `internal defines' fix from SCM. Original ChangeLog entry:
585 1998-07-09 Radey Shouman <radey@colorage.com>
587 * eval.c (ceval_1): Modifications to allow rewriting of interal
588 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
589 body of which it is the CAR is macro expanded by m_expand_body,
590 which rewrites internal DEFINE.
592 (m_expand_body): Added.
594 (m_macroexp1): Added argument to control error checking:
595 m_expand_body may speculatively expand forms in the wrong
596 environments. Made argument number checks conditional on
599 (m_body): Added, error checks bodies and inserts the ISYM tokens.
601 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
604 (m_cond): (m_case): (m_quote): Modified to avoid destructively
605 changing their argument forms. Since m_expand_body
606 speculatively macro expands forms the process must be
609 (m_ident_eqp): Fixed to use proper environment.
611 (renamed_ident): Added DEFER_INTS_EGC.
613 Added prototypes for static functions.
619 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
620 is false, do not produce an error for unbound variables, return a
621 pointer to cell_undef instead.
623 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
627 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
628 destructively changing their argument forms. Since m_expand_body
629 speculatively macro expands forms the process must be reversible.
631 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
632 SCM_IM_LET introduced by named lets.
634 (scm_m_letstar): Use scm_m_body instead of bodycheck.
636 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
637 scm_letrec. scm_letrec1 does not check for a null binding and
638 takes an additional argument to specify the ISYM of the body. Use
639 scm_m_body instead of bodycheck.
641 (scm_m_let): Use scm_m_body instead of bodycheck.
643 (scm_m_expand_body, scm_macroexp): New.
645 (unmemocopy): Account for ISYMs introduced by scm_m_body.
647 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
648 check=1. Throw error for internal defined that have not been
649 rewritten by scm_m_expand_body.
651 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
652 Removed prototype for SCM_APPLY.
654 * tags.h: Added extern declaration of scm_isymnames.
656 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
658 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
660 * lang.c: New file: Beginning of multi-language support.
662 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
664 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
665 (scm_dynamic_wind): Added argument checking for the after guard so
666 that we don't add garbage on the dynwind chain.
667 (scm_swap_bindings): Added.
669 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
670 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
671 (scm_isymnames): New isyms for multi-language support.
673 * eval.c (scm_nil, scm_t): New symbols.
674 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
675 forms for multi-language support.
677 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
679 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
681 Renamed functions in the random function library interface
682 from scm_i_XXX --> scm_c_XXX.
684 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
686 * ports.c (scm_putc): fix line-buffering.
688 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
690 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
691 scm_set_ptob_XXX --> scm_set_port_XXX.
693 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
695 * ports.c, ports.h (scm_make_port_type): New interface for
696 creation of port types (replaces scm_newptob). Just as for the
697 smobs, we need to separate the internal representation of smob
698 types from the interface, so that we easily can add new fields and
699 rearrange things without caring about backward compatibility.
700 This change was forced by the need in GOOPS to create classes
701 representing port types.
702 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
703 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
704 scm_set_ptob_seek, scm_set_ptob_truncate,
705 scm_set_ptob_input_waiting_p): New setters.
706 (scm_newptob): Rewritten to use scm_make_port_type. For backward
708 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
709 (scm_prinport): Removed.
710 (scm_port_print): Added.
711 (scm_print_port_mode): Added.
712 (void_port_ptob, print_void_port, close_void_port, noop0):
713 Removed. Removed #include "genio.h" Added #include "objects.h",
716 * fports.c (prinfport): Moved code from ports.c.
718 (scm_fptob): Removed. Instead use new interface.
719 (scm_make_fptob): Added. (Need to create basic ports in a
720 specific order in ports.c.)
722 * strports.c (scm_stptob, prinstpt, noop0): Removed
723 (scm_make_stptob): Added.
725 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
726 (scm_make_sfport): Added.
728 * filesys.c (scm_dir_print): Don't use the port printing code.
729 Instead provide specific directory printer.
731 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
733 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
736 * smob.c (scm_smob_print): Handle non-existing type name nicely.
737 Removed #include "genio.h"
739 * objects.c (scm_make_port_classes): New function ptr.
741 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
743 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
745 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
746 allow the 1st argument to be a fdes or filename as well as a
747 port (as in the filesys.c version).
749 * filesys.c (scm_truncate_file): removed.
751 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
753 * readline.c, readline.h: Removed.
755 * objects.c, objects.h (scm_port_class): Added.
756 (scm_class_of): Look up port class in scm_port_class.
757 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
758 SCM_INOUT_PCLASS_INDEX): Added.
761 * Makefile.am: Removed genio.c, genio.x.
765 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
767 * init.c: Make sure that scm_post_boot_init_modules is called only
768 once. (Important when using a dumped image.; Thanks to Bernard
771 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
773 * guardians.c (scm_guardian_zombify): Separate scanning for
774 zombies from marking the pairs of the free list.
776 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
777 use the macros. (Thanks to Michael Livshin.)
779 * eval.c (scm_m_lambda): Let bodycheck check the body of the
780 lambda. Let your sins be purified by the blood of the lambda.
781 (Thanks to Eric Hanchrow.)
783 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
784 (Thanks to Valdis Kletnieks.)
786 Fixes for EMX from Mikael Ståldal.
788 * filesys.c: #include <io.h>, if we have it.
789 * scmconfig.h.in: Regenerated.
791 * stime.c (ftime): Delete declaration for this function --- let
792 the system supply it.
794 Cleanups from John Bley.
796 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
798 * gsubr.c: Don't include "gsubr.h" twice.
800 Cleanups for compilation on Irix 6, from David Kaelbling.
802 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
803 regex_t pointer. This is what the callers have, mostly.
804 (scm_regexp_exec): Don't forget to pass the `rx' argument to
805 scm_regexp_error_msg.
807 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
808 int. That way, if we get a warning on this line, it's more likely
809 that we're really missing bits we care about.
811 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
814 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
815 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
816 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
817 cast at all is more appropriate in every case. At the moment, we
818 assume everywhere that SCM is an integral type anyway.
820 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
822 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
823 read_pos after scm_fill_buffer.
825 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
828 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
829 fports.c (fport_fill_buffer): implement the interface change.
831 * ports.c (scm_fill_buffer): interface change: no longer increments
832 read_pos past the character that's returned. it seems clearer to
833 leave it to the caller to decide what to do (thanks Jim).
835 * vports.c (sf_fill_buffer): put the read char into the buffer
836 as well as returning it.
838 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

845 (st_seek): don't allow string to be extended if seeking past
846 the end of a read-only port.
848 1999-07-12 Gary Houston <ghouston@easynet.co.uk>
850 * strports.c (st_seek): change the resize checks.
852 * ports.c (scm_ftruncate): throw error if offset works out negative.
854 * strports.c (st_flush): increase string size in blocks of
855 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
856 it's greater and reset read_buf_size.
857 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
858 to be maintained for output ports too (it holds the written
859 part of the string, while write_buf may have unwritten buffer
861 (st_truncate): rewritten.
862 (top of file): added a few notes.
864 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
866 Patch from Greg Badros:
867 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
868 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
869 (function pointer) argument to scm_make_gsubr and scm_make_subr
870 calls. This avoids warnings in C++ programs using guile-snarf.
872 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
874 * strports.c (st_grow_port): set pt->read_pos. set
875 pt->read_buf_size one less than pt->write_buf_size if there's
876 an unwritten char at the end of the string. similarly for
878 (st_resize_port): renamed from st_grow_port.
879 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
880 seek from read_end instead of write_end for SEEK_END.
881 (st_ftruncate): calculate current length using readbuf, not write
883 (scm_strport_to_string): use read_buf_size for length.

888 * strports.c (scm_strport_to_string): new procedure.
889 (scm_call_with_output_string, scm_strprint_obj): use
890 scm_strport_to_string.
891 used SCM_INUM0 instead of SCM_MAKINUM (0) in a few places.
893 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
895 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)
897 Fri Jun 25 22:14:32 1999 Greg Badros <gjb@cs.washington.edu>
899 * smob.c: added scm_make_smob_type_mfpe (), scm_set_smob_mfpe ();
900 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
901 and "bigneg" smob types.
903 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
904 SCM_RETURN_NEWSMOB macro. Added protos for new functions in
907 * *.c: Use scm_make_smob_type_mfpe, instead of scm_newsmob, and
908 use SCM_NEWSMOB or SCM_RETURN_NEWSMOB in constructors instead of
909 SCM_NEWCELL and setting the CAR/CDR by hand.

992 * dynl-dl.c (sysdep_dynl_link): Added parenthesis around the
993 trinary conditional in order for the flag computation to be
996 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
998 * struct.c, struct.h:
1000 In order to support different kinds of deallocation, a destructor
1001 slot has been added to struct vtables. This allows for structs
1002 containing pointers to other memory blocks.
1004 (scm_struct_i_free): New hidden struct slot. Holds destructor for
1005 instances to this vtable.
1006 (scm_struct_free_0): New destructor: Doesn't deallocate data.

1076 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1077 around the condition of an `if', `while', etc., even if the
1078 condition is a macro invocation that expands to something
1079 surrounded by parens. It's more readable.
1081 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1082 proper lists, and of the appropriate lengths.

1107 * gc.h (scm_mallocated): Fix declaration.
1108 (Thanks to Greg Harvey.)

1114 * stime.c (bdtime2c): Initialize lt->gmtoff and lt->tm_zone from
1115 sbd_time. (Thanks to Eric Hanchrow.)
1117 Fix from Ken Raeburn <raeburn@raeburn.org>:
1118 * weaks.c (scm_make_weak_vector): Add another extra slot before
1119 vector contents, to be used only during garbage collection.
1120 * weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
1121 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
1123 (scm_weak_size, scm_n_weak): Deleted.
1124 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
1125 vectors without allocating new storage during GC, using
1126 scm_weak_vectors as the head of the chain.
1127 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1128 instead of stepping through an array.
1129 (scm_gc_sweep): Update offset used to find start of weak vector to
1131 (scm_init_storage): Set scm_weak_vectors to EOL.
1133 Fix from Ken Raeburn <raeburn@raeburn.org>:
1134 * gc.c (already_in_gc): New variable.
1135 (scm_igc): Set and clear already_in_gc; abort if it's set at
1138 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
1140 Fix from Gary Houston:
1141 * fports.c (local_seek): Signal an error if the seek fails.
1142 * ports.c (scm_lseek): Don't check return value of port's seek
1143 function; it's its job to signal an error if there's a problem.
1145 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
1147 * strports.c (scm_call_with_output_string): Don't include the
1148 extra character at the end of the string in the result.
1150 * ioext.c (scm_read_line): Switch to reading properly.
1152 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
1153 scmsigs.c, strports.c, vports.c: Install the sources which
1154 actually correspond to the changes described below. I got the
1155 ChangeLog entries and the patch from two different places...
1157 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1159 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1160 it shows up as terrible performance, as we GC constantly.
1162 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1163 newline. A bit faster, and definitely hairier.
1164 (scm_read_line): Count newlines here instead.
1166 * strings.c (scm_take_str): New function.
1167 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1168 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
1169 scm_take_str, to avoid copying the string.
1171 Add some simple-minded support for line buffered ports.
1172 * ports.h (SCM_BUFLINE): New flag for ports.
1173 * init.c (scm_init_standard_ports): Request line-buffering on
1174 the standard output port.
1175 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1177 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1178 and there's a newline to be written, flush the port.
1180 Gary Houston's open-buffer port patches:
1182 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1184 * ports.c: (scm_lseek): clear buffers even if just reading current
1187 * fports.c (local_fclose): call local_fflush unconditionally.

1190 1999-04-25 Gary Houston <ghouston@easynet.co.uk>
1192 * ports.h (scm_port): make read_pos a pointer to const.
1193 strports.c: take care of rw_active and rw_randow.
1194 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
1195 strports.c (scm_mkstrport): check that pos is reasonable.
1196 ioext.c (scm_ftell, scm_fseek): use lseek.
1197 (SCM_CLEAR_BUFFERS): macro deleted.
1198 ioext.c (redirect_port: use ptob fflush, read_flush.
1199 ports.h (scm_ptobfuns): add ftruncate.
1200 ports.c (scm_newptob): set ftruncate.
1202 ports.c (scm_ftruncate): new procedure.
1203 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
1204 strports.c (st_seek, st_grow_port): new procs.
1205 fports.h (scm_port): change size types from int to off_t.
1206 ports.c (scm_init_ports): initialise the seek symbols here
1207 instead of in ioext.c.
1208 strports.c (scm_call_with_output_string): start with an empty
1209 string, so seek and ftruncate can be used.
1211 gdbint.c: adjust string port usage.
1213 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1215 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1216 equivalent to fflush for the read buffer.
1217 * ports.c (scm_newptob): set read_flush.
1218 ports.c (void_port_ptob): set read_flush.
1219 fports.c (local_read_flush): new proc. add to ptob.
1220 strport.c (st_read_flush): likewise.
1221 vport.c (sf_read_flush): likewise.
1222 fports.h (struct scm_fport): remove random member. there's nothing
1223 left but fdes. leaving it as a struct to allow for future changes.
1224 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1225 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1226 ptob proc if the read buffer is filled.
1228 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1230 * ports.h (scm_port): add a rw_random member and replace
1231 reading and writing members with rw_active member.
1232 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1234 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1236 * ports.h (struct scm_port_table): add writing and reading members
1237 to replace write_needs_seek: it isn't good enough for non-fports.
1238 ports.c, ioext.c, fports.c: corresponding changes.
1239 (struct scm_port_table): give it a typedef and rename to scm_port.
1240 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1241 corresponding changes.
1243 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
1245 * ports.c (scm_newptob): bugfix: set seek member.
1246 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
1247 and generalised to all port types.
1249 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
1251 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1252 signals (it was only being done for handlers installed from Scheme).
1253 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1254 waiting for input caused an EINTR error from read.
1256 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1258 * ports.h (struct scm_port_table): make all the char members
1259 unsigned, so they convert to int without becoming negative if large.
1261 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1263 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1264 with threads enabled. rename this procedure to
1265 fport_wait_for_input and take a port instead of a fdes.
1266 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1268 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1269 get readline support working again: use fdopen to get FILE objects.
1271 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1273 * gc.c (scm_init_storage): install an atexit proc to flush the
1275 (cleanup): the new proc. it sets a global variable which can be
1276 checked by the ptob flush procs to avoid trying to throw
1277 exceptions during exit. not very pleasant but it seems more reliable.
1278 * fports.c (local_fflush): check terminating variable and if set
1279 don't throw exception.
1280 * CHECKME: that the atexit proc is installed if unexec used.
1282 * throw.c (scm_handle_by_message): don't flush all ports here.
1283 it still causes bus errors.
1285 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1286 and move to ioext.c.
1288 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1290 * ports.c (scm_char_ready_p): check the port buffer and call the
1291 ptob entry if needed.
1293 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1294 ptob initialisers. use it in char-ready
1296 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1298 * vports.c (sfflush): modified to write a char (since softports
1299 currently use shortbuf.)
1301 * fports.c (scm_standard_stream_to_port): moved to init.c and
1304 * init.c (scm_init_standard_ports): make stdout and stderr
1305 unbuffered if connected to a terminal. with stdio they
1306 were line-buffered by default.
1308 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1311 * ports.h (scm_ptobfuns): change fflush return to void.
1312 change flush proc definitions.
1314 * strports.c (scm_call_with_output_string): get size from
1315 buffer instead of port stream.
1316 (st_flush): new proc.
1318 * ports.h (struct scm_port_table): added write_end member,
1319 as an optimisation. set it where write_buf_size is set.
1321 * ports.h (struct scm_port_table): change stream from void *
1322 back to SCM. SCM presumably must be large enough to hold a
1323 pointer (and probably vice versa but who knows.)
1324 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1326 (scm_puts): rewritten
1327 * fports.c (local_ffwrite, local_fputs): removed.
1328 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)
1329 * vports.c (sfputc, sfputs, sfwrite) likewise.
1330 * ports.c (write_void_port, puts_void_port): removed.
1331 (putc_void_port, getc_void_port, fgets_void_port): likewise.
1333 * ports.c (scm_lfwrite): rewritten using fport.c version.
1335 * fports.c (local_fputc): deleted.
1337 * ports.c (scm_add_to_port_table): initialise write_needs_seek.
1339 * ports.h (scm_ptobfuns): add seek function pointer.
1340 * fports.c: set it to local_seek, new procedure.
1343 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1344 use ptob for seek. take ptob instead of fport arg.
1346 * ports.h (struct scm_port_table): new member write_needs_seek,
1347 replaces reading member in fport struct.
1349 * vports.c (sfgetc): store the getted char into the buffer.
1350 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1351 the Scheme interface is still a procedure that gets a char.
1352 (scm_make_soft_port): set up the port buffer (shortbuf).
1354 * fports.c (local_fgetc, local_fgets): deleted.
1355 * strports.c (stgetc): likewise.
1356 * ports.c: scm_generic_fgets: likewise.
1358 * ports.h (scm_ptobfuns): add fill_buffer.
1359 * ports.c (scm_newptob): assign it.
1360 * strports.c (scm_mkstrport): set up the buffer.
1361 put just the string into the stream, not cons (pos stream).
1362 (stfill_buffer): new proc.
1364 * ports.h: fport buffer moved into port table: to be
1365 used for all port types.

1374 scm_getpeername, scm_recv, scm_send, scm_recvfrom,
1376 use SCM_FPORT_FDES. use SCM_OPFPORTP not SCM_FPORTP.
1378 * posix.c (scm_getgroups): use SCM_ALLOW/DEFER_INTS.

1436 ports.c fports.c ioext.c posix.c socket.c net_db.c filesys.c:
1437 removed all uses of SCM_DEFER/ALLOW ints for now. they were mainly
1438 just protecting errno. some may need to be put back.

1443 *fports.c (print_pipe_port, local_pclose, scm_pipob): deleted.

1640 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1642 * numbers.c (isfinite): Define this macro if not defined: Return a
1643 non-zero value if X is finite. (From ISO C 9x standard.)

1696 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1698 Most of this batch of changes is about how to deal with extended
1699 types when an object system is loaded into Guile. A nice object
1700 system is capable of representing Guile's types as class objects.
1702 For example, we want a regular expression to be of class <regex>.
1703 But regular expressions are smobs which aren't under direct
1704 control of the object system, so there has to be some mechanism
1705 which informs the object system that a new class should be created
1706 which can represent the smob type. I call this a "wrapper class".
1708 * objects.c: #include "smob.h";
1709 (scm_class_keyword): Removed. (Class is automatically created by
1711 (scm_smob_class): Array of smob classes indexed by smobnum.
1712 (scm_make_extended_class): "Plugin" function pointer for creation
1713 of wrapper classes for smob and struct types.
1714 (scm_class_of): Handle compiled closures. (Currently regarded as
1716 Use scm_smob_class to handle smob types;
1717 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1718 through scm_smob_class;
1721 * smob.c (scm_newsmob): Also create a wrapper class if
1722 scm_smob_class has been initialized.
1724 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1725 type code and smobnum.
1727 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1728 (scm_struct_table): Weak key table with auxilliary information for
1729 struct types. Currently used for names and wrapper classes.
1730 (scm_struct_ihashq): Hash function for structs.
1731 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1732 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1733 for accessing names of vtables. The record implementation in
1734 boot-9.scm currently uses the setter to record the name of record
1735 types. When the object system is initialized, it can use this
1736 information to create wrapper classes with suitable names.
1737 (scm_init_struct): Allocate scm_struct_table.
1738 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1739 (struct tags are a finite resource and we might want to restrict
1740 the use of tags to vtables only. E.g., Goops only uses tags for
1742 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1744 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1747 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1748 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1749 Used for access of struct table entries.
1751 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1752 (scm_hash_fold): New procedure. Used to process all entries in a
1753 hash table (in no particular order).
1755 Argh! For the umpteenth time I got compilation errors because of
1756 the "intuitive" name `kw'. This has to have an end:
1758 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1759 "kw" --> "keywords" everywhere.
1760 (I doubt that this will cause big compatibility problems since the
1761 application interface is unaffected.)
1763 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1765 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1767 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1768 column inums to native form.
1770 Improvement of backtraces: Introduces a new stack narrowing
1771 specifier, #t, for the inner cut. (See further in the comments in
1772 stacks.c:narrow_stack ().)
1774 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
1775 (Used to flag certain system procedures which shouldn't turn up in
1778 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1779 modules which aren't "user" modules and the code of which
1780 shouldn't turn up in backtraces.)

1783 Extract the lookup closure from an environment.
1784 (scm_system_module_env_p): New function: Return non-#f if MODULE
1787 * stacks.c: #include "eval.h"; #include "procprop.h";
1788 (narrow_stack): Handle new narrowing specifier #t.
1790 * debug.c (scm_procedure_name): Use name property in the default
1793 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1795 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1797 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1798 procedure throughout.
1800 * print.c (scm_iprin1): Removed extraneous space when printing
1801 procedure-with-setters.
1803 Entity and operator setter slots were introduced as a complement
1804 to the <procedure-with-setter> type in order to support entities
1805 and operators with setters in a reasonable and efficient way.
1806 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1809 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1821 * objects.h (SCM_OBJ_CLASS_REDEF): New macro: Find class slots
1822 directly through the instance.
1824 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1826 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1827 scm_struct_i_flags instead of scm_vtable_index_layout!
1829 * list.c (scm_list_star): New procedure.
1831 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1912 SYMB now point to const.
1914 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1916 * print.c (scm_iprin1): Use scm_procedure_name instead of
1917 scm_procedure_property for compiled closures.
1919 * tags.h (scm_tc7_pws): New procedure type. Four representations
1920 for procedure-with-setters were considered before selecting this
1923 1. A closure where the CODE and ENV slots are used to represent
1924 the getter and a new SETTER slot is used for the setter. The
1925 original getter is stored as a `getter' procedure property. For
1926 closure getters, the CODE and ENV slots contains a copy of the
1927 getter's CODE and ENV slots. For subr getters, the CODE contains
1930 2. A compiled closure with a call to the getter in the cclo
1931 procedure. The getter and setter are stored in slots 1 and 2.
1933 3. An entity (i.e. a struct with an associated procedure) with a
1934 call to the getter in the entity procedure and the setter stored
1935 in slot 0. The original getter is stored in slot 1.
1937 4. A new primitive procedure type supported in the evaluator. The
1938 getter and setter are stored in a GETTER and SETTER slot. A call
1939 to this procedure type results in a retrieval of the getter and a
1940 jump back to the correct eval dispatcher.
1942 Representation 4 was selected because of efficiency and
1945 Rep 1 has the advantage that there is zero penalty for closure
1946 getters, but primitive getters will get considerable overhead
1947 because the procedure-with-getter will be a closure which calls
1950 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1951 <procedure-with-setter>, but together with rep 2 it suffers from a
1952 three level dispatch for non-GOOPS getters:
1954 cclo/struct --> dispatch proc --> getter
1956 This is because the dispatch procedure must take an extra initial
1957 argument (cclo for rep 2, struct for rep 3).
1959 Rep 4 has the single disadvantage that it uses up one tc7 type
1960 code, but the plan for uniform vectors will very likely free tc7
1961 codes, so this is probably no big problem. Also note that the
1962 GETTER and SETTER slots can live directly on the heap, using the
1963 new four-word cells.
1965 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

2051 may be contamination by Cygnus internal releases. If you re-run

2079 * Makefile.am: New files: guardians.c, guardians.x, guardians.h
2081 * guardians.c, guardians.h (scm_make_guardian,
2082 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
2083 scm_get_one_zombie, scm_init_guardian): This is an implementation
2084 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
2085 David Eby (1993) "Guardians in a Generation-Based Garbage
2086 Collector" ACM SIGPLAN Conference on Programming Language Design
2087 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
2088 /pub/scheme-repository/doc/pubs/guardians.ps.gz
2089 Author: Michael N. Livshin.
2091 * gc.h (SCM_MARKEDP, SCM_NMARKEDP): New macros.
2093 * gc.c (scm_igc): Call scm_guardian_gc_init and
2094 scm_guardian_zombify.
2096 * init.c (scm_boot_guile_1): Call scm_init_guardian.
2098 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2100 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
2103 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2105 Move the procedure slots of entities to invisible slots (so that
2106 we can have operator class objects which themselves are entities).
2107 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
2108 SCM_STRUCTF_ENTITY): New constants.
2110 * struct.c (scm_make_struct): Allocate "invisible" room for
2111 procedures if SCM_STRUCTF_ENTITY is set in vtable.
2113 * gc.c (scm_gc_mark): Mark entity procedures.
2115 * struct.c, struct.h (scm_alloc_struct): Renamed from alloc_struct
2117 (scm_struct_init): Renamed from init_struct and made global.
2119 * objects.h (SCM_ENTITY, scm_entity): Removed.
2120 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
2121 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
2123 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
2125 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
2126 of syntactic forms, similar to SCM_PROC.
2127 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
2128 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
2129 for the name symbols when needed.
2131 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
2133 * Makefile.in: Regenerated.
2135 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
2137 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
2138 take the address of _into; it might be a register. Just have
2139 scm_debug_newcell return the new cell.
2140 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2141 taking the address of a place to store it as an argument.
2142 * gc.h (scm_debug_newcell): Change declaration.
2143 (Thanks to Greg Harvey.)
2145 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2147 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
2148 Replaces old names serial-array-copy! and serial-array-map!.
2150 * evalext.c (map-in-order): New name. Replaces serial-map.
2152 1998-12-05 Jim Blandy <jimb@totoro.red-bean.com>
2154 * smob.c (freeprint): New function.
2155 (freecell): Use it to print freed objects, for slightly easier
2158 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2160 * backtrace.c (display_frame): Made more robust. Doesn't throw an
2161 error if no source properties can be found for a frame. (Thanks
2162 to Christian Lynbech.)
2164 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2166 * objects.h: Removed slots direct_supers and direct_slots from the
2167 definitions of the rudimentary classes described by objects.h.
2169 * objects.c, objects.h (scm_entity_p): New procedure. Together
2170 with the predicates scm_procedure_p and scm_struct_p, this
2171 predicate makes it possible to differ between structs, entities
2174 * modules.c, modules.h (scm_resolve_module): New function.
2176 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2178 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2179 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2182 * objects.c (scm_entity_p): New procedure.
2184 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
2185 for asubrs, rpsubrs, lsubrs and lsubr_2s.
2187 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2189 * procprop.h (scm_i_procedure_arity): Added declaration.
2191 * procprop.c (scm_i_procedure_arity): Made global; New code to
2192 handle operators and entities.
2193 (scm_procedure_property): No need to call scm_procedure_p since
2194 scm_i_procedure_arity now does all necessary type checking.
2195 Added #include "objects.h".
2197 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2198 s_add_hook_x --> s_remove_hook_x.
2199 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
2200 Added #include "procprop.h"
2202 * feature.c, feature.h (scm_reset_hook_x): New procedure.
2203 (scm_make_hook): Optional argument defines number of arguments to
2205 (scm_make_named_hook): Take number of args as second arg.
2206 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2207 boot-9.scm for a while); First arg is the hook. The rest are
2208 arguments passed on to the hook procedures.
2210 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2212 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2213 scm_logbit_p): Do the computation in ulongs. This is not as nice
2214 as doing it in bignums, but at least it's good enough for
2215 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2217 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2218 subexpressions. (Thanks to Charbel Jacquin.)
2220 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2222 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2223 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2224 (scm_make_named_hook): New function.
2226 * feature.c: Added #include "eval.h".
2228 * modules.c (scm_make_module): Beautify the module.
2230 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2232 * modules.c, modules.h: New files: C interface to modules. (This
2233 is necessary in order to interface the object system to Guile
2234 properly. The guts of these modules will be replaced by the new
2235 module system in the future.)
2237 * init.c: Added #include "modules.h"
2238 (scm_boot_guile_1): Call scm_init_modules.
2239 (invoke_main_func): Call scm_post_boot_init_modules.
2241 * Makefile.am: Added modules.c, modules.x, modules.h.
2243 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2245 * procs.c: #include "objects.h"
2246 (scm_procedure_p): Return #t also on structs which are operators.
2248 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2249 <operator-metaclass> and <entity-class> to <standard-class>,
2250 <operator-class> and <entity> in order to conform with STKlos
2253 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2254 which isn't an operator.
2255 (SCM_APPLY): Ditto, but jump to badproc.
2257 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2259 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2260 Previously, structs implanted in code were interpreted as forms
2261 the operator of which was a gloc. We solve this by checking for
2262 the zero in the emulated vcell in the struct vtable. Since
2263 implanted structs always will look like forms with a gloc
2264 operator, execution will only be slowed down by maximally one
2265 extra test-and-branch per application.
2267 * evalext.c (scm_definedp): Removed check for isyms; Added a
2268 second optional argument: It is now possible to supply an
2269 evaluation environment in which to look for the symbol.
2271 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2273 * readline.c (scm_init_readline): Set
2274 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2276 * coop.c (coop_condition_variable_wait): Removed
2277 (coop_condition_variable_wait_mutex): Folded logic of
2278 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2279 prevent condvar signal lossage. Previously, another thread could
2280 start to run after unlocking the mutex but before putting the
2281 current thread on the wait queue. If that thread then would
2282 signal the first, the signal would be lost. (Thanks to Christian
2285 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2287 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2290 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2292 * objects.c (scm_i_make_class_object): Renamed from
2293 make_class_object; exported; error checking moved to
2294 scm_make_class_object and scm_make_subclass_object.
2295 (scm_make_class_object, scm_make_subclass_object): Use
2296 scm_i_make_class_object.
2297 (scm_make_subclass_object): Let the subclass have same metaclass
2300 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2302 * debug.c (scm_debug_options): Bugfix: Set the value of
2303 scm_stack_checking_enabled_p after setting debug options;
2304 #include "stackchk.h". (Thanks to Richard Polton.)
2306 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2308 * unif.c (scm_array_contents): removed unnecessary test for 0
2311 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2313 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2314 Replaced by macro `collect' in boot-9.scm.
2316 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2318 * eval.c (scm_copy_tree): Copy source properties if existent.
2320 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2321 don't, we may end up passing memoized source to a transformer.)
2323 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2325 * stack.c (get_applybody): Help function which lookups the first
2326 body form of the apply closure.
2327 (read_frames): Prevent the source of the first form of the apply
2328 closure from being recorded. This would only be confusing.
2330 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2331 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2333 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2335 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2337 (read_frames): Use SCM_MACROEXPP.
2339 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2341 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2342 don't contain interesting information since all arguments are
2343 present in the frame which applies the compiled closure anyway.);
2344 Skip the transformer application frames.
2346 * print.c (scm_iprin1): Print gsubrs as primitives.
2348 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2350 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2352 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2353 that we can identify these in a backtrace. (This change doesn't
2354 introduce any significant speed penalty.)
2356 * eval.c: Added note about `serial-map' using scm_map.
2358 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2359 readline options. They should reside in their own options array.
2361 * readline.c, readline.h (scm_readline_options,
2362 scm_readline_opts): Moved readline options here.
2364 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2366 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2367 SCM_ROCHARS instead of SCM_CHARS.
2369 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2370 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2372 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2374 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2375 This is quite important since the latter clears the
2376 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2377 every single character read...
2379 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2381 * print.c (scm_iprin1): Removed suspect looking (and indeed
2382 malevolent) semicolon after test for user supplied closure print
2383 procedure. (Thanks to Telford Tendys.)
2385 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2386 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2387 starting to search the list. Removed call to sloppy_mem_check.
2389 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2390 procedures: Same as scm_delq_x et al, but delete maximally one
2393 * options.c (scm_options, scm_init_options): GC-protect option
2394 values of type SCM. (Thanks to Telford Tendys.)
2396 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2398 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2399 make sure that there always is a "real" scm_lookupcar.
2401 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2403 * read.c, read.h (scm_read_opts): New read options
2404 "history-length" and "history-file".
2405 (scm_read_options): Stifle history to history length.
2407 * readline.c (scm_read_history, scm_write_history): New procedures.
2409 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2411 * eval.h (scm_macro_eval_x): Removed declaration.
2413 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2414 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2415 Renamed and made global.
2417 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2418 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2420 * evalext.c, evalext.h: New files. Contain non-R5RS things
2421 having to do with evaluation.
2423 * evalext.c (scm_serial_map): New procedure: Version of `map'
2424 which guarantees that the procedure is applied to the lists in
2426 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2427 returns a list of the results of the body forms instead of the
2428 result of the last body form.
2429 (scm_definedp, scm_m_undefine): Moved from eval.c
2431 * evalext.h (scm_m_sequence_to_list): Added declaration.
2433 * macros.c, macros.h: New files.
2434 (scm_procedure_to_syntax, scm_procedure_to_macro,
2435 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2436 scm_macro_name, scm_macro_transformer): Moved from eval.c
2437 (scm_make_synt): Moved from eval.c
2439 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2441 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2444 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2446 * debug.c, print.c: Added #include "macros.h".
2448 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2450 This change adds the ability to use `unread-char' multiple times
2451 without interspersed reads and adds the new procedure
2452 `unread-string'. The change is optimized for the common case of
2453 unreading a single character. This is also the reason behind the
2454 choice to store characters in the port itself: in most cases no
2455 extra malloc is required.
2457 The amount of code in some macros in ports.h has been increased to
2458 the extent that they would fit better as C functions, but, since
2459 this code belongs to the port representation, such functions
2460 should be placed in ports.c which would cause calls back and forth
2461 between ports.c and genio.c. That is not good for performance.
2462 Also, keeping them as macros allows the compiler to do some
2463 optimizations which are needed to make the current interface
2464 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2466 One benchmark (Guile startup time) indicates an increase of
2467 loading speed of 1%. Another (reading (using `read') boot-9.scm
2468 10 times) shows no change in performance.
2470 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2471 made to find a beautiful solution.)
2473 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2474 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2475 character. (SCM_CLRDY clears all.)
2476 (SCM_N_READY_CHARS): New macro: Returns number of unread
2477 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2478 (struct scm_port_table): New fields: `entry' contains port table
2479 index, `cp' points to last unread char, `cbuf' is the buffer for
2480 unread chars, `cbufend' points after end of the character buffer.
2482 * ports.h, ports.c (scm_unread_string): New procedure.
2483 (scm_grow_port_cbuf): New function.
2485 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2487 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2488 to read unread characters. Use SCM_TRY_CLRDY instead of
2491 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2493 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2495 * genio.c, genio.h (scm_ungets): New function.
2497 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2500 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2502 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2503 declarations. (Thanks to Russ McManus.)
2505 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2507 * numbers.c (num2long): As a software archeologist, I'm proud of
2508 this finding! :) Preliminary dating suggests an almost 4 year old
2509 remnant from the SCM ancestor. The sample has been removed from
2510 the finding site and is now safely stored in the repository.
2512 * numbers.h: Removed prototype for num2long.
2514 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2516 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2517 array as second arg.
2518 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2519 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2520 * gh.h: Updated and added prototypes.
2522 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2524 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2526 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2528 * guile-snarf.in: Never generate an empty file. (Thanks to
2531 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2532 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2533 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2534 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2535 gh_new_procedure5_0): Specify argument types, to appease C++
2536 compilers. (Thanks to Brad Bowman.)
2538 Bug reports from Russ McManus:
2539 * guile-snarf.in: If the CPP environment variable is set, use that
2540 as the C preprocessor, instead of the preprocessor autoconf
2542 * snarf.h (SCM_PROC): Cast the function pointer passed to
2543 scm_make_gsubr, to satisfy C++.
2545 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2546 Use the handler passed, instead of ignoring it and using
2547 gh_standard_handler. (Thanks to Etienne Bernard.)
2549 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2551 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

2571 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2574 * script.c (scm_compile_shell_switches): Define
2575 use-emacs-interface in the root module, so the repl code can see
2576 it. See today's change to top-repl in ice-9/boot-9.scm.
2578 * filesys.c (set_element, get_element): Make sure that `element'
2579 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2580 Boekemeier and Jorgen "forcer" Schaefer.)
2582 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2584 * chars.c (scm_charnames): In ASCII character name table, make
2585 newlines print as #\newline by default, not #\nl.
2587 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2588 alphabetical order. Oh thrills. But it helps me know how far
2589 along in the compilation I am.
2590 * Makefile.in: Regenerated.
2592 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2594 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2595 #bytes(...) to #y(...), and syntax for short vectors from
2596 #short(...) to #h(...). This may seem nutty, but, like the other
2597 uniform vectors, byte vectors and short vectors want to have the
2598 same print and read syntax (and, more basic, want to have read
2599 syntax!). Changing the read syntax to use multiple characters
2600 after the hash sign breaks with the conventions used in R5RS and
2601 the conventions used for the other uniform vectors. It also
2602 introduces complexity in the current reader, both on the C and
2603 Scheme levels. (The Right solution is probably to change the
2604 syntax and prototypes for uniform vectors entirely.)
2606 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2608 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2609 (Thanks to Jorgen "forcer" Schaefer.)
2610 * ports.h (SCM_NOFTELL): New flag.
2611 * fports.c (local_fgets): If it's set, use the generic fgets.
2612 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2614 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2616 * script.c (scm_compile_shell_switches): Add handling of -q switch
2617 (inhibit loading of user init file).
2618 (scm_shell_usage): Add usage text for -q switch.
2619 (scm_compile_shell_switches): Always load user init file first if
2620 it is loaded at all.
2622 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2624 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2625 and is now broken under NetBSD. I can't fathom what it's trying
2626 to do, so I've replaced it with something that I do understand,
2627 which seems to work, and which isn't broken on NetBSD. "Progress?
2628 You Decide." (Thanks to Perry Metzger.)
2630 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2631 signed/unsigned comparison.
2633 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2635 Warning fixes from Greg Harvey:
2636 * unif.c (scm_array_set_x): initializer for pos
2637 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2638 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2639 initializers for field_type, since EGCS so desparately wants to
2641 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2642 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2643 when GUILE_DEBUG is defined.
2644 * dynwind.h (scm_wind_chain): Same.
2645 * ports.h (scm_pt_size, scm_pt_member): Same.
2646 * print.h (scm_current_pstate): Same.
2647 * procs.h (scm_make_cclo): Same.
2649 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2651 Handle short and long long uniform arrays properly. (Thanks to
2653 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2654 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2655 scm_tc7_llvect (long long vectors).
2657 Change the way libguile and boot-9.scm are timestamped, to try to
2658 get rid of these spurious mismatch warnings. Now both
2659 libguile/versiondat.h and ice-9/version.scm are generated directly
2660 by the configuration process, rather than having version.scm
2661 generated directly, and libguile/versiondat.h generated by the
2662 Makefile, which is generated by configure. It seems that
2663 sometimes the Makefile would change, but versiondat.h depends on
2664 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2665 * Makefile.am (versiondat.h): Target removed; this is generated
2666 directly by the configure script now.
2667 (BUILT_SOURCES): Remove versiondat.h.
2668 * versiondat.h.in: New file, transformed by the configure script
2670 * Makefile.in: Regenerated.
2672 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2673 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2674 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2675 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2676 if we want to use them in a header file some day, we can. (Thanks
2677 to Michael Livshin.)
2679 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2680 SCM numbers, so we won't have rollover problems; the range of a
2681 signed long in milliseconds is about 25 days. (Thanks to Karl
2684 Don't redefine sleep and usleep; fix this problem now.
2685 * coop.c (sleep, usleep): Remove declarations; we don't use or
2686 redefine these any more.
2687 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2688 job of usleep and sleep in a thread-friendly way. We can use
2689 these in the rest of Guile. Define versions for systems both with
2690 and without iselect.
2691 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2692 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2693 we're just using it, not redefining it, we can use a K&R style
2695 (sleep): Declare this, too, if the system hasn't.
2696 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2697 scm_uthread_sleep if they're available; otherwise, just call the
2699 * scmconfig.h.in: Regenerated.
2701 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2703 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2705 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2707 * threads.c: Doc fix.
2709 The argument type of usleep varies from system to system,
2710 as does the return type. We really shouldn't be redefining usleep
2711 at all, but I don't have time to clean that up before the 1.3.
2712 release. It's on the schedule for afterwards. (Thanks to Julian
2714 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2716 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2717 * scmconfig.h: Regenerated.
2719 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2720 right way to handle system variation. Autoconf's approach is the
2722 * simpos.h (scm_software_type): Declaration deleted.
2724 * script.c (scm_find_executable): Don't test if unix is #defined
2725 here; first, NetBSD doesn't #define it, and second, it's the wrong
2726 way to go about these things. (Thanks to Perry Metzger.)
2727 (dld_find_executable): Delete this MSDOS support code. This isn't
2728 the way we want to support this; it needs to be rethunk at a
2731 * genio.c (scm_do_read_line): Don't just politely check that the
2732 line was either non-empty or EOF. Abort if it's empty and not
2735 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2737 * scmconfig.h.in: Regenerated.
2739 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2742 * genio.c (scm_do_read_line): Count lines correctly when the file
2743 doesn't end in a newline.
2745 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2747 * genio.c (scm_do_read_line): Maintain the line count correctly.
2748 (Thanks to Harvey J. Stein and Greg Harvey.)
2750 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2753 * numbers.c (big2str): Protect t from garbage collection until
2754 we're done. (Thanks to Gary Houston.)
2756 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2758 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2760 * Makefile.in: Regenerated.
2762 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2763 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2766 Do magic to mix reads and writes on stdio FILE-based ports.
2767 (Thanks to Christian Lynbech.)
2768 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2770 (pre_read, pre_write): New functions.
2771 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2772 local_fputs): Call them.
2773 (local_fflush): Mark the port as ready for reading and writing.
2774 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2775 flags on new port objects. This might not be accurate --- who
2776 knows what state the FILE * is in when we get it --- but it won't
2777 do extraneous calls to fflush or fseek, so it's no worse than the
2778 behavior before this change.
2779 * ports.h: Add comment.
2781 Centralize the creation of port objects based on stdio FILE * in
2782 fports.c; don't just throw them together anywhere.
2783 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2784 what the rest of Guile wants. Don't set the revealed count;
2785 that's only appropriate for stdin, stdout, stderr.
2786 (scm_standard_stream_to_port): This function does set the revealed
2788 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2789 not scm_stdio_to_port.
2790 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2791 * fports.c (scm_open_file): Same.
2792 * posix.c (scm_pipe): Same.
2793 * socket.c (scm_sock_fd_to_port): Same.
2794 * ioext.c (scm_fdopen): Same.
2795 (scm_freopen): Moved from here to...
2796 * fports.c (scm_freopen): ... here. This is really something that
2797 munges the internals of an fport, so it should go here.
2798 * fports.h (scm_stdio_to_port): Adjust prototype.
2799 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2800 * ioext.h (scm_freopen): Prototype removed.
2802 * filesys.c (set_element, get_element): This can work on both pipe
2803 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2806 * scmconfig.h.in: Regenerated.
2808 Change the definition of the functions in scm_ptobfuns so that
2809 they get passed the port object, not the port's stream.
2810 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2811 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2812 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2813 Pass the port itself to the scm_ptobs function.
2814 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2815 scm_generic_fgets): Same.
2816 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2817 getc_void_port, fgets_void_port, close_void_port): Just change the
2818 argument names; these functions don't really do anything.
2819 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2820 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2821 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2822 Also, use prototyped definitions, and get rid of the extra
2824 (scm_fptob, scm_pipob): We don't need casts here any more.
2825 * strports.c (prinstpt): Use prototype declarations.
2826 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2827 and use SCM_STREAM to get the string info. Also, use prototyped
2828 definitions, and get rid of the extra declarations.
2829 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2832 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2833 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2835 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2836 scm_fgets, for consistency.
2837 (scm_fptop, scm_pipob): References updated.
2839 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2841 Include the source location in error messages for scripts.
2842 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2843 stack is still there when we catch the error.
2844 * throw.c (handler_message): If we are handling an error with a
2845 message, then put together the proper arguments and call
2846 scm_display_error, instead of scm_display_error_message. That
2847 displays source location, if it can find it.
2849 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2851 * gc.c (scm_unprotect_object): Change this so that calls to
2852 scm_protect_object and scm_unprotect_object nest properly.
2853 (scm_protect_object): Doc fixes.
2855 * strings.c (scm_string_set_x): Require the argument to be a
2856 writable string, not a substring or a symbol.
2857 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2858 (Thanks to John Redford and Charbel Jacquin.)
2860 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2862 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2864 * eval.c (safe_setjmp): Remove this misunderstanding.
2865 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2868 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2870 * libguile.h: Mark these as C declarations, for compilation by C++
2873 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2874 __cplusplus clause. I seriously doubt this ever worked the way
2875 the author seems to have intended.
2877 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2879 Utterly needless cleanups to hopelessly messy code.
2880 * ports.c: Doc fixes.
2881 (scm_fflush): Moved to ...
2882 * genio.c (scm_fflush): ... here, amongst all the other port
2883 method invocation functions.
2884 * genio.h, ports.h: The prototype moves too.
2886 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2888 * backtrace.c (display_error_body): The current frame does not
2889 always have a parent frame; consider a function called directly
2890 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2893 * alloca.c (alloca): Undo yesterday's changes, and simply call
2894 malloc directly for storage, and abort if we don't get what we
2895 want. The situation is much simpler --- just call malloc. Emacs
2896 has bizarre/evil requirements (signal handlers might malloc unless
2897 you set this global flag, so you have to set the flag around all
2898 calls to malloc) which we are certainly not going to conform to,
2899 so we can do the simple and obvious thing.
2901 * coop.c (coop_condition_variable_wait): Make this function
2902 static. It's only useful internally --- you should never just
2903 wait on a condition variable.
2904 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2906 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2908 * unif.c (scm_array_set_x): Accept any kind of number as an
2909 element for a uniform vector of doubles. This is more consistent
2910 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2912 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2913 works; I can't conveniently test it myself. (Thanks to Dvid
2914 Tillman for the bug report.)
2916 * init.c: Doc fixes.
2918 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2919 from here, not from scm_compile_shell_switches (which is a pretty
2920 dumb place to do it).
2921 (scm_load_startup_files): New function.
2922 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2923 * script.c (scm_compile_shell_switches): Don't load the startup
2925 (scm_ice_9_already_loaded): Variable moved.
2926 * init.c (scm_load_startup_files): Prototype for new function.
2927 * gh_init.c (gh_enter): Doc fix.
2929 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2931 Some anti-warning changes from Greg Harvey.
2932 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2933 warnings when it doesn't understand our NORETURN declarations in
2935 * posix.c (scm_mknod): Similar.
2937 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2939 * posix.c (scm_getpwuid): If we can't find an entry, return our
2940 own message, instead of using scm_syserror --- the getpwMUMBLE
2941 functions don't set `errno' to anything interesting.
2943 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2945 Get rid of warnings from the cooperative threading system.
2946 * threads.h (scm_single_thread_p, scm_yield,
2947 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2948 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2949 scm_wait_condition_variable, scm_signal_condition_variable): Add
2950 prototypes for these Scheme-visible functions.
2951 * coop-defs.h (coop_next_runnable_thread,
2952 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2953 Prototypes for these here, even though they're from iselect.c.
2954 (coop_condition_variable_wait, coop_join): Add prototypes.
2955 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2956 scm_threads_free_condvar): Make these smob functions static.
2957 * coop-threads.h (coop_init): Give this a real prototype.
2958 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2959 (coop_next_runnable_thread): No need to provide prototype; it's in
2962 * scmconfig.h.in: .detarenegeR
2964 * iselect.c, threads.c: Doc fixes.
2966 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2968 * Makefile.in: Regenerated with a patched automake, to get
2969 dependency generation right when using EGCS.
2971 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2972 warning. (Thanks to Robert Pluim.)
2974 * inet_aton.c (inet_aton): Reassure the compiler that the
2975 arguments to the <ctype.h> macros are all unsigned characters, not
2978 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2980 Getting rid of more warnings...
2981 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2982 today's change to ../configure.in.
2983 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2984 * scmconfig.h.in: Regenertaded.de.,.__
2985 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2986 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2989 * readline.c: Doc fix.
2990 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2991 * readline.h (scm_filename_completion_function): Add prototype.
2992 (scm_init_readline): Make this into a prototype.
2994 * readline.c (scm_filename_completion_function): Use SCM_PROC to
2995 declare this, instead of calling scm_make_subr manually.
2997 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
2999 * readline.h (scm_init_readline): Add prototype for this.
3000 (scm_init_readline): Make this a real prototype.
3002 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3004 Warning fixes from Maciej Stachowiak:
3005 * backtrace.h (scm_display_application, scm_backtrace): Add
3007 * debug.c (scm_m_start_stack): Make this function static.
3008 * fluids.h (scm_fluid_p): Add prototype.
3009 * procprop.c (scm_i_procedure_arity): Make this function static.
3010 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3011 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
3012 * root.h (scm_dynamic_root): Add external prototype.
3013 * scmsigs.h (scm_usleep): Add external prototype.
3014 * script.h (scm_init_script): Use prototype, not K&R decl.
3015 * stacks.h (scm_stack_id): Add external prototype.
3016 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3018 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3020 * gh.h: took out the definitions of vset and vref, since they are
3021 replaced by the proper vector routines that correspond to the R4RS
3024 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3026 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3027 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3028 third argument, a C expression that should result in a SCM value,
3029 which is used to initialize the variable. Reimplemented
3030 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3033 * version.h (scm_libguile_config_stamp): Add prototype.
3034 (From Maciej Stachowiak.)
3036 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3038 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3039 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3041 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3043 * print.c (scm_iprin1): Rather than having one i, and using it in
3044 several places, declare a fresh i local to each block where it is
3045 used, and give it a signedness appropriate to its use in each case.
3046 (scm_iprlist): Same.
3048 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3049 comparison warnings.
3051 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3052 signed/unsigned clashes.
3054 * posix.h (scm_tmpnam): Added prototype.
3056 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3057 scm_make_subclass_object): Add external prototypes.
3059 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3060 comparison is okay here.
3062 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3064 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3065 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3067 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3070 * load.c (swap_port): Make this function static.
3072 * load.c (scm_search_path): Make max_path_len and max_ext_len
3073 unsigned, since they're compared against string sizes.
3075 * load.c (init_build_info): Make i unsigned.
3077 * ioext.h (scm_read_line): Add prototype.
3079 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3080 scm_hash_fn_remove_x): Make hash bucket index local variable k
3081 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3082 accurately as possible.
3084 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3085 comparisons, and range checking to make sure those casts are
3088 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3089 signed/unsigned comparisons.
3091 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3092 avoid signed/unsigned comparisons.
3093 * smob.h (scm_numsmob): Change extern declaration to match.
3095 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3096 avoid signed/unsigned comparisons.
3097 * ports.h (scm_numptob): Change extern declaration to match.
3098 (scm_current_load_port, scm_set_port_line_x,
3099 scm_set_port_column_x): New prototypes.
3101 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3102 test code, and it causes warnings.
3104 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3105 gh_uniform_vector_ref): Added prototypes.
3107 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3108 debugging support unconditionally. That's backtrace.c, stack.c,
3109 debug.c, and srcprop.c.
3110 (EXTRA_libguile_la_SOURCES): Omit those from here.
3111 * Makefile.in: Regenerated.
3113 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3115 * options.c (scm_options): Bugfix: Allow empty list of options!
3117 * debug.c, debug.h (scm_single_step): Removed.
3118 (scm_with_traps): New procedure. This procedure could easily be
3119 written in Scheme but needs to be highly optimized.
3121 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3123 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3124 Check SCM_TRAPS_P before trapping.
3126 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3128 Changes to avoid signed/unsigned comparison warnings.
3129 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3130 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3131 so they can have appropriate types for each application. Make i
3132 signed. Use initializers in some spots. I'll probably pay for
3134 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3135 (scm_must_realloc): Make nm unsigned.
3136 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3137 (scm_init_storage): Use prototype-style definition, and make the
3139 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3140 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3142 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3143 avoid signed/unsigned comparison warnings, and because the return
3144 value of readlink may be -1. Don't bother casting the third
3145 argument to readlink.
3147 * filesys.c (scm_dirname, scm_basename): Move these to their own
3148 page, at the end of the file.
3149 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3151 * eval.h (scm_eval_options_interface): Add external prototype for this.
3152 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3154 * eval.c (scm_lookupcar1): Make this static.
3156 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3157 Make these prototype declarations, not K&R-style.
3159 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3160 unsigned comparison warning.
3162 * appinit.c: File removed. It had a single function in it, empty,
3163 whose reason for existence is explained in no documentation or
3164 comment. I think it's there as a default for some Tcl-style
3165 initialization, but Tcl abandoned that approach a while ago.
3166 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3167 (BUILT_SOURCES): Remove appinit.x.
3168 * Makefile.in: Regenerated.
3170 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3172 * Makefile.in: Regenerated using the last public version of
3173 automake, not the hacked Cygnus version.
3175 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3177 Remove Totoro kludge.
3178 * Makefile.in, scmconfig.h.in: Regenerated.
3179 * init.c, readline.c: Don't check if TOTORO is #defined.
3181 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3183 * Makefile.am: Adjust for new thread configuration system.
3184 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3185 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3187 (THREAD_LIBS): Definition deleted; automake will generate such
3188 things automatically.
3189 * Makefile.in: Regenerated.
3191 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3193 Simplify smob and port marking; set the mark bit in the generic
3194 marking code, and make marker routines only responsible for
3195 turning up outgoing pointers.
3196 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3197 before calling the marking function. Don't call the marking
3198 function if it's zero.
3199 * markers.c (scm_mark0): Just return #f. This function isn't
3200 necessary at all now, but it's harmless to call it. We'll leave
3201 it in so other folks' code doesn't croak at link time.
3202 (scm_markcdr): Don't call SCM_SETGC8MARK.
3203 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3204 * dynl.c (mark_dynl_obj): Same.
3205 * root.c (mark_root): Same.
3206 * srcprop.c (marksrcprops): Same.
3207 * unif.c (markra): Same.
3208 * variable.c (scm_markvar): Same.
3209 * ports.c (scm_markstream): Same.
3210 (void_port_ptob): Specify zero for our marking function.
3211 * debug.c (debugobjsmob): Same.
3212 * dynwind.c (guardsmob): Same.
3213 * filesys.c (dir_smob): Same.
3214 * fluids.c (fluid_smob): Same.
3215 * fports.c (scm_fptob, scm_pipob): Same.
3216 * mallocs.c (mallocsmob): Same.
3217 * regex-posix.c (regex_t_smob): Same.
3218 * smob.c (freecell, flob, bigob): Same.
3219 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3220 * throw.c (jbsmob, lazy_catch_funs): Same.
3222 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3224 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3225 scm_copy_tree on code in order not to let memoized code to leak
3226 out. Thus, scm_copy_tree needs to copy vectors as well since
3227 quasiquote can introduce evaluated code also inside vector
3230 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3232 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3234 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3235 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3238 * unif.c: Say that ivect and uvect are of type signed and unsigned
3239 long instead of int in commentary so that it correctly describes
3242 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3244 * stime.c: Removed declaration of strptime. (It should be
3245 declared by the system headers. If it turns out that some systems
3246 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3248 * stime.h: Renamed TIMEH --> STIMEH
3250 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3251 to increase portability, don't use structure assignment.
3252 (Thanks to Nicolas Neuss.)
3254 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3256 (finalize_fd_sets): Added empty statement after last case label.
3257 (Thanks to Nicolas Neuss.)
3259 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3262 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3264 * init.c, readline.c: OK, I won't have these readline.x bug
3265 reports anymore. We've had them since April. The current reason
3266 is a completely unintelligible failure of totoro.red-bean.com to
3267 do the test for rl_getc_function in libreadline correctly. This
3268 kludge overrides the test if we're on totoro so that the snapshot
3269 generation process can work.
3271 * readline.c: Define a strdup replacement if not existent on system.
3273 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3275 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3276 This change makes scm_make_vector R5RS compatible. We cannot keep
3277 the third argument since people want to be able to deduce the form
3278 of the C function call only by looking at R5RS. (At the same time
3279 we have removed some unnecessary complexity!)
3281 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3282 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3283 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3284 argument in call to scm_make_vector.
3286 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3288 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3289 This macro is useful in applications.
3291 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3293 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3294 (scm_parse_path, scm_search_path): New Scheme level procedures.
3296 * load.h (scm_internal_parse_path, scm_parse_path,
3297 scm_search_path): Declared.
3299 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3301 * filesys.c (dirname, basename): New procedures.
3303 * init.c (scm_boot_guile_1): Removed condition around
3306 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3307 new data type (guards) for representation of C level guards and
3308 data on the wind chain.
3309 (scm_internal_dynamic_wind): New function.
3311 * dynwind.h: Declare scm_internal_dynamic_wind.
3313 * root.h (scm_root_state): Added scm_cur_loadp.
3315 * root.c (mark_root): Added comment about cur_loadp.
3317 * load.c: #include "dynwind.h";
3318 (scm_primitive_load): Use scm_inner_dynamic_wind to update
3321 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3323 * ports.c (current-load-port): New procedure.
3325 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3327 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3328 not a tty, return #f.
3330 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3331 to Julian Satchell and Roland Kaufmann.)
3333 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3334 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3336 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3338 * debug.h, debug.c (scm_start_stack): New function. Implements
3339 the guts of old scm_m_start_stack.
3341 * debug.c (scm_m_start_stack): Use scm_start_stack.
3343 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3344 start_stack and restart_stack. (These have static scope.)
3346 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3348 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3349 readline functions to come in release 2.3. (Thanks to Chet
3351 (handle_errors): Use the above functions.
3353 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3355 * readline.c: Improvements for readline support: Handle errors
3356 better; Implement before-read-hook.
3358 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3360 * init.c (scm_boot_guile_1), readline.c: Test for
3361 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3362 assure that we have version >= 2.1.)
3364 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3366 * readline.c (scm_readline): Defer interrupts while we're calling
3369 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3370 away the string to add_history.
3371 (completion_function): Do completion for readline. (Thanks to
3373 (scm_filename_completion_function): New procedure: Filename
3375 (current_input_getc): New function. Use this one instead of
3376 standard getc from readline.
3378 * throw.c, throw.h (scm_handle_by_throw): New function: This
3379 handler throws errors to next handler on the dynwind chain.
3381 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3383 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3386 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3388 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3390 (scm_procedure_properties): Modified to return arity together with
3392 (scm_procedure_property): Added the read-only property `arity'.
3393 (scm_set_procedure_property_x): It is an error to set the `arity'
3396 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3397 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3399 * procprop.h (scm_sym_arity): New symbol.
3401 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3402 to set the dispatch procedure of an operator or entity object.
3404 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3405 Made procedure slots read-only.
3407 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3408 scm_tcs_cons_gloc case in zero args switch; Fixed args
3409 construction for operators in scm_tcs_cons_gloc case in two args
3412 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3414 * fluids.c: Removed use of assert.h (in order to avoid
3417 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3419 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3421 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3422 change makes the evaluator safer at the cost of evaluation speed.
3423 It handles the case when the user has added a non-immediate
3424 improper end of the application form, e.g., `(+ 0 . x)'.
3425 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3426 minimize the extra cost as much as possible. The new code is
3427 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3428 problem with structs planted directly in the code (e.g. by a
3429 macro). This no longer causes segmentation fault. (Thanks to
3432 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3433 arg `proc' in order to be able to throw errors; New argument
3436 * Removed extra #include "debug.h"
3438 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3440 * scmsigs.c: Declare usleep as returning void on some systems.
3441 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3444 * coop.c (usleep): Return void on some systems.
3446 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3448 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3450 * coop.c: Changed return type of usleep to int.
3452 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3453 isn't found in the OS.
3455 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3456 isn't enabled. (Thought that I had made this change ages ago...)
3458 * iselect.c: Declare bzero if not defined by OS.
3460 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3462 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3463 condition. (Thanks to John Tobey.)
3465 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3466 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3469 * __scm.h: Start the long-term project of moving to POSIX threads.
3470 Phase 1: Classification of all critical sections.
3471 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3472 for A sections. (See comments in __scm.h for details.)
3474 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3475 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3477 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3479 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3480 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3481 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3482 dependencies on $(srcdir)/Makefile.in
3483 $(top_builddir)/config.status in order to avoid circularity.
3485 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3486 from argc if argc was 0 initially.
3488 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3489 in generation of libpath.h.
3491 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3493 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3494 libguile from 2 to 3.
3496 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3498 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3500 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3502 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3503 scm_set_port_column_x, scm_port_filename,
3504 scm_set_port_filename_x): Removed optional arguments. Added
3505 proper argument checking.
3507 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3508 stack size in machine words.
3510 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3511 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3512 to Ole Myren Röhne.)
3514 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3516 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3517 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3519 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3522 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3523 procedure apply: Copy argument lists before pushing them unto the
3524 environment so that the environment won't get mutated due to
3525 manipulation of procedure arguments. This should perhaps be
3526 regarded as a temporary solution until someone finds a more
3527 efficient one. (Thanks to Maciej Stachowiak.)
3529 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3531 * script.c (scm_compile_shell_switches): Use "guile" as default
3532 zero arg if argc is NULL.
3534 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3536 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3537 is zero. (Thanks to Dirk Herrmann.)
3539 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3541 * ports.c (scm_add_to_port_table): First line is now line 0
3542 (was 1). (Interface changed according to suggestion by Per
3545 * backtrace.c (display_header): Add 1 to line and column numbers
3546 when presenting them to the user.
3548 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3549 from debug.c --> eval.c
3551 * eval.h, eval.c (scm_eval_options_interface): New options
3553 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3554 i.e. stacks for new threads.
3556 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3558 * eval.c (unsafe_setjmp): Removed with #if 0.
3560 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3563 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3564 to avoid compiler warnings.
3566 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3568 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3570 * throw.c (handler_message): Print message on current error port
3571 instead of default error port. (Thanks to Maciej Stachowiak.)
3573 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3575 * ports.c (scm_add_to_port_table): allocate in units of
3576 struct scm_port_table *, not struct scm_port_table.
3577 * posix.c (scm_close_pipe): remove the port from the port table
3579 Thanks to Rob Engle for both fixes.
3581 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3583 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3584 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3586 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3588 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3590 * backtrace.c (display_error_body, display_backtrace_body),
3591 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3592 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3593 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3594 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3597 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3598 don't receive the jmpbuf arg anylonger.
3599 (scm_catch): Don't accept a #f tag.
3600 (scm_throw): Check that key is a symbol.
3601 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3603 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3605 * async.c (async_pending): Removed declaration.
3607 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3609 * dynwind.c (scm_wind_chain): New debug function.
3611 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3612 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3613 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3614 extra layer of functions around the body and handler of a thread.
3615 This extra layer makes sure that the handler is called in the
3616 dynamic context of the surround (= empty dynwind list), but under
3617 the *dynamic root* of the body. We can not use the dynamic root
3618 of the surround since that root belongs to another thread => stack
3619 is not handled correctly. It may seem ugly to use this extra
3620 layer, but the extra cost in terms of execution time is really
3621 negligible compared to the total amount of time required to create
3622 a thread, and it would reduce maintainability to duplicate the
3623 crucial and complicated steps performed by cwdr.
3625 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3626 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3627 get re-enabled. The important effect of this is that interrupts
3628 are blocked during thread switching so that thread data structures
3629 don't risk getting messed up by an unfortunate signal.
3630 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3631 seems to do more aggressive optimization which actually move
3632 instructions around in these macros in a fatal way. Therefore:
3633 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3634 just superstitious...)
3635 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3636 This macro should be used instead of SCM_ASYNC_TICK since the
3637 latter doesn't do context switches any more.
3639 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3640 instead of SCM_ASYNC_TICK.
3642 * coop.c, iselect.c: Since thread switches are now performed with
3643 interrupts masked, we can't use the old mechanism of delivering
3644 signals immediately when they arrive. Signals must instead be
3645 delivered when the asyncs run *after* the end of the critical
3646 section in scm_internal_select. But this also means after context
3647 switch so that the signal will be delivered to a different thread.
3648 To avoid this, I have changed the protocol of
3649 coop_wait_for_runnable_thread and friends so that they are allowed
3650 to return the original thread. So, if a signal arrives during
3651 scm_internal_select, we won't any longer be forced do a context
3652 switch, but can remain in the same thread and deliver the signal
3655 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3656 scm_asyncs_pending and made it global.
3658 * iselect.c: Small fixes.
3660 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3661 coop_condition_variable_init, coop_condition_variable_wait,
3662 coop_condition_variable_signal): Changed return type from `void'
3663 to `int'. This is to adhere closer to the pthreads interface.
3664 This, in turn, is part of an attempt to provide C versions of the
3665 mutex and condition variable primitives which can be part of a
3666 frontend to COOP or pthreads.
3668 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3669 coop_condition_variable_destroy): New functions.
3671 * coop-threads.c (scm_wait_condition_variable): Use
3672 coop_condition_variable_wait_mutex.
3674 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3675 Definitions moved to coop-defs.h.
3677 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3678 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3679 scm_cond_destroy): New C interface to mutecis and cond vars.
3681 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3683 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3685 * iselect.c: Now several threads can wait on the same file
3686 descriptor. The behaviour is compatible with OS select: All
3687 threads waiting for the fd return with the same status.
3689 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3691 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3692 Can spawn a thread from application C code.
3694 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3696 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3697 gh_doubles2scm): New functions.
3699 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3701 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3702 commented-out version of gh_eval_str()
3704 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3706 * socket.c (scm_bind): free soka after use.
3708 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3710 * stime.c (tzvar): new variable.
3711 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3712 avoid memory leaks when allocating.
3714 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3716 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3719 * gc.c, tags.h: Doc fixes.
3721 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3723 * eval.c (macro-eval!): Removed. This function was a design bug.
3724 It allowed memoized code to leak out to the scheme level. Most
3725 things that you could do with `macro-eval!' can be done with
3728 1997-12-20 Tim Pierce <twp@skepsis.com>
3730 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3731 scm_fgets now depends on ftell(3) to know how many bytes were
3734 1997-12-15 Tim Pierce <twp@skepsis.com>
3736 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3737 dealing with strings.
3739 1997-12-13 Tim Pierce <twp@skepsis.com>
3741 Make %read-line more suitable for implementing read-line efficiently.
3742 * ioext.c (scm_read_line): Strip the terminating newline from a
3743 string, and return a cons of the string and its terminator.
3745 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3746 of the string that is read is stored in this memory location.
3747 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3748 * genio.c, genio.h (scm_do_read_line): Update caller.
3749 * ports.h (scm_ptobfuns): Update typedef.
3750 * fports.c (scm_fptob, scm_pipob): Update struct.
3752 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3754 * filesys.c (set_element): Return file descriptor.
3755 (fill_select_type): Return the highest file descriptor.
3756 (scm_select): Tell select about the highest file descriptor. On
3757 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3758 Therefore the extra overhead for calculating the maximum fd seems
3759 to be more than compensated. Is this correct? In any case,
3760 scm_internal_select will be much faster with this info.
3761 (scm_select, fill_select_type, set_element): Don't accept any kind
3762 of object in the file descriptor list or vector.
3764 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3766 * iselect.c (finalize_fd_sets): Bugfix.
3768 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3770 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3771 when using scm_internal_select (since we might switch to another
3774 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3776 * simpos.c (scm_system): always define: use sysmissing if not
3777 available. Check for HAVE_SYSTEM instead of _Windows (does
3778 Windows lack system or does it have an unusable one?).
3779 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3780 Let the argument be optional: if not supplied, call system(NULL).
3782 * ports.c (scm_close_port): relax the type check from OPPORTP to
3783 PORTP; closing a closed port is allowed.
3785 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3787 * fports.c (scm_fgets): Return if the last char in a chunk is
3788 newline. When fgets returns a string whose length is `size-1', it
3789 is ambiguous whether a whole line was retrieved, so we must check
3790 explicitly whether a line terminator is present.
3792 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3794 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3795 before taking the CDR. (Thanks to Harald Meland.)
3797 * filesys.c (scm_stat): Slightly optimized.
3799 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3801 * ports.c (scm_close_port): Make sure the port is open before
3804 * guile-snarf.in: Pass args through to gcc in a way that preserves
3805 whitespace boundaries. (Thanks to Greg Badros.)
3807 1997-12-02 Tim Pierce <twp@skepsis.com>
3809 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3810 statement. (Thanks to Doug Evans for pointing this out.)
3812 1997-12-01 Tim Pierce <twp@skepsis.com>
3814 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3816 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3818 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3819 errno macro expansion of this field name. (errno is a C
3820 preprocessor macro on some systems.)
3822 1997-11-29 Tim Pierce <twp@skepsis.com>
3824 * iselect.c: Doc fix.
3826 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3828 * init.c (scm_start_stack): Removed initialization of
3829 scm_the_last_stack_var.
3831 * backtrace.h: Declare scm_the_last_stack_var.
3833 * backtrace.c: Define scm_the_last_stack_var.
3835 * root.c (mark_root): Don't mark the_last_stack_var.
3837 * root.h (scm_root_state): Removed the_last_stack_var.
3839 * throw.c: Added #include "fluids.h"
3840 (ss_handler): `the-last-stack' is now a fluid.
3842 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3843 --> the_last_stack_fluid.
3845 * backtrace.c: Added #include "fluids.h"
3846 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3847 (scm_backtrace): `the-last-stack' is now a fluid.
3849 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3850 after scm_init_fluids.
3852 1997-11-28 Tim Pierce <twp@skepsis.com>
3854 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3856 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3857 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3859 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3861 * iselect.c (coop_next_runnable_thread,
3862 coop_wait_for_runnable_thread): Disable interrupts so that no
3863 async is executed before a potential error_revive.
3864 (scm_internal_select): Disable interrupts during the parts of the
3865 code which manipulate the sleep queue and the file descriptors.
3867 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3869 * Makefile.am: Added iselect.c and iselect.h.
3871 * coop.c (coop_qinit): Initialize fields used by
3872 scm_internal_select.
3873 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3874 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3875 replacement in iselect.c.
3876 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3877 coop_join): If GUILE_ISELECT enabled, use
3878 coop_wait_for_runnable_thread instead of
3879 coop_next_runnable_thread.
3880 (usleep, sleep): New replacements for system functions if
3881 GUILE_ISELECT is enabled.
3883 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3885 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3887 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3888 iselect.h. Implement Scheme level `select' using
3889 scm_internal_select. (See NEWS.)
3891 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3893 * init.c: Call scm_init_iselect.
3895 * iselect.h, iselect.c: New files. Implements
3896 scm_internal_select. (See NEWS.)
3898 1997-11-27 Tim Pierce <twp@skepsis.com>
3900 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3901 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3902 and scm_must_free, since ultimately the string returned will be copied
3903 by scm_makfrom0str anyway. Also, read any characters that may have
3904 been pushed onto the port with scm_ungetc.
3905 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3906 * ioext.c (scm_read_line): Free string after Guilifying it.
3907 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
3909 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3911 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3913 * gh.h: Safely wrap prototypes for c++ usage.
3915 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3917 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3918 gh_repl (argc, argv).
3920 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3922 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3923 and to invoke scm_shell().
3924 (gh_launch_pad): took out the loading of boot-9.scm from here,
3925 since it is probably best to let the user control that. In fact,
3926 gh_repl() now invokes scm_shell() which does that.
3928 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3930 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3933 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
3935 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
3936 yesterday's underscore patch. (Thanks to Marius Vollmer for
3939 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
3941 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
3942 DLSYM_ADDS_USCORE is not defined.
3944 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
3946 * gh_data.c (gh_uniform_vector_length):
3947 (gh_uniform_vector_ref): started implementing the uniform types in
3950 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3952 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3953 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3955 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3957 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3958 configure.in was changed).
3960 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3962 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3963 * Makefile.in: Regenerated.
3965 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3967 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3968 OPORT is an `open' port, not an output port.
3970 * filesys.c (scm_close, set_element, get_element, scm_chown,
3971 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
3972 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
3973 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
3974 scm_close_port, scm_port_line, scm_set_port_line_x,
3975 scm_port_column, scm_set_port_column_x, scm_port_filename,
3976 scm_set_port_filename_x, scm_port_mode,
3977 scm_close_all_ports_except, scm_set_current_output_port,
3978 scm_set_current_error_port): Likewise
3979 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3980 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
3982 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
3983 * backtrace.c (display_backtrace_body): Likewise
3984 * fports (scm_setvbuf): Likewise
3985 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
3986 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
3987 scm_getpeername, scm_send, scm_sendto): Likewise
3988 * unif.c (scm_uniform_array_write): Likewise
3990 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
3992 Minor problems with substring-related tag changes.
3993 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
3994 exactly what we want to leave in to detect substrings.
3995 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
3996 * tags.h: Fix diagrams and comments describing the S tag bit;
3997 remove vestigial remarks about the D tag bit.
3998 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
3999 * strings.c: Formatting tweaks.
4001 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
4002 variable first; then SCHEME_LOAD_PATH, with a warning message.
4003 (scm_parse_path): New function.
4004 * script.c: Doc fixes.
4006 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
4008 Readline support, from Daniel Risacher.
4009 * readline.c, readline.h: New files.
4010 * init.c: #include "readline.h".
4011 (scm_boot_guile_1): Call scm_init_readline, if we have it.
4012 * Makefile.am (libguile_la_SOURCES): Include readline.c.
4013 * Makefile.in: Regenerated.
4014 * scmconfig.h.in: Regenerated, after change to ../configure.
4016 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4018 * gh.h: gh_vector_set -> gh_vector_set_x
4020 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4022 * gh_data.c (gh_vector_set_x): changed name to make it consistent
4023 with the ! -> _x mapping when going from Scheme to C.
4025 1997-10-19 Mark Galassi <rosalia@cygnus.com>
4027 * gh.h (gh_reverse):
4035 (gh_assoc): added these gh_ functions implemented as macros.
4037 * gh_predicates.c (gh_null_p):
4038 (gh_string_equal_p): added these two missing predicates.
4040 * gh_list.c (gh_append):
4045 (gh_set_cdr_x): added these routines as I go through and try to
4046 complete the picture R4RS functions that should be mirrored in the
4049 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4051 * tags.h (scm_tc7_substring): Changed the comment and code to
4052 conform with the changes below. Folks! We have suddenly two new
4053 free tc7 codes!!! Jummy, jummy!

4073 (scm_gc_sweep): Likewise.
4074 * eval.c (SCM_CEVAL): Don't handle mbstrings.
4075 * eq.c (scm_equal_p): Use SCM_TYP7S, not SCM_TYP7SD.
4076 * tags.h (SCM_TYP7SD): Removed.
4077 (SCM_TYP7D): Removed.
4078 (scm_tc7_mb_string): Removed.
4079 (scm_tc7_mb_substring): Removed.
4080 * print.c (scm_iprin1): Handle char printing directly. Don't
4082 Don't include "mbstrings.h".
4083 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
4084 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
4086 Don't include "mbstrings.h".
4087 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
4088 (SCM_SYMBOL_SLOTS): Define as 4.
4089 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
4090 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
4091 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
4092 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
4093 struct.c, threads.c, throw.c, unif.c, variable.c: Use new

4109 (scm_do_read_line): Renamed from scm_gen_read_line.
4110 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
4111 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
4113 1997-10-12 Mark Galassi <rosalia@cygnus.com>
4115 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
4117 * gh_test_c.c (c_vector_test): some improvements on the vector
4120 * gh.h (gh_vector): this used to exist but do the wrong thing.
4121 Now it (almost) does the right thing, though it takes a list
4122 instead of the individual arguments. I need to see how it could
4124 (gh_list_to_vector): added this function as a macro. Corresponds
4125 to Scheme's (list->vector ...).
4126 (gh_vector_to_list): added this function as a macro. Corresponds
4127 to Scheme's (vector->list ...).
4129 * gh_data.c (gh_vector_ref): renamed from gh_vref to
4130 gh_vector_ref, so that it resembles the Scheme routines more.
4131 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
4132 resembles the Scheme routines more.
4133 (gh_make_vector): this used to be (stupidly) called gh_vector().
4134 This is the right name, since it does the same thing as the Scheme
4135 (make-vector ...) procedure.
4137 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4139 * ports.h: #include "libguile/print.h"
4141 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
4142 Some indentation fixes.
4144 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
4145 longer a user field; New field: class_flags.
4147 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
4149 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
4151 * gh_data.c (gh_bool2scm): new function which replaces
4152 gh_int2scmb(), which is now tagged as obsolete.
4154 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4156 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4157 macros should by convention not test for NIMPness.)
4158 (SCM_COERCE_OPORT): Adjust indentation.
4160 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4161 SCM_NIMP test before SCM_PRINT_STATE_P.
4163 * struct.c, struct.h, gc.c: Renamed:
4164 scm_struct_i_layout --> scm_vtable_index_layout
4165 scm_struct_i_vcell --> scm_vtable_index_vcell
4166 scm_struct_i_vtable --> scm_vtable_index_vtable
4167 scm_struct_i_printer --> scm_vtable_index_printer
4168 scm_struct_i_vtable_offset --> scm_vtable_offset_user
4170 * struct.c (scm_print_struct): Use new printer slot; Default
4171 printing: Also output hex code of vtable so that type identity
4172 will be indicated as well.
4173 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4174 Removed struct_printer_var; Removed struct-vtable-offset;
4175 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4176 vtable-offset-user): New constants.
4178 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
4179 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
4180 If this slot contains a procedure, use that to print structures of
4181 the type represented by this vtable.
4183 * print.c (scm_iprin1): Don't print arguments of macro
4184 transformers. (They are always: exp env.); Bugfix: Unmemoize
4185 transformer source with correct environment.
4187 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4189 Streamlining of call-with-dynamic-root:
4191 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
4192 there is now only one catch.
4193 (cwdr_outer_body): Removed.
4194 (cwdr_handler): New function.
4195 (scm_internal_cwdr): New function to perform the function of cwdr
4196 but take args that are more useful to C code. Also, the handler
4197 is now invoked *outside* of the new dynamic root, like the docs
4198 say. We no longer have to catch absolutely all errors, the caller
4199 is responsible for using a handler that does not throw, if he
4201 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4202 * root.h (scm_internal_cwdr): New prototype.
4204 Even more but risky streamlining:
4206 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4207 allocation of the jumpbuf of a root continuation. The changes
4208 below are controlled by it. They are now deactivated.
4209 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4210 the JMPBUF of the scm_rootcont to NULL before returning.
4212 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4213 when they are non-NULL.
4214 (scm_gc_mark): Likewise, mark only when non-NULL.
4216 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4217 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4219 * gc.c (scm_done_malloc): New function.
4220 gc.h (scm_done_malloc): New prototype.
4222 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
4223 (struct scm_print_state) [revealed]: New field.
4224 (scm_print_state_vtable): Make visible to the outside world for
4225 type checking purposes.
4226 (scm_valid_oport_value_p): New prototype.
4228 * print.c (scm_valid_oport_value_p): New function to check whether
4229 a certain value is acceptable as a port argument.
4230 (scm_print_state_vtable): New variable.
4231 (scm_free_print_state): Set `revealed' field to false.
4232 (scm_iprin1): Call user supplied closure printer with
4233 scm_printer_apply. Print in the traditional way when there isn't
4234 one or when it returns #f.
4235 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4236 Accept a port/print-state pair in addition to just a port.
4237 (scm_prin1): Don't return the print_state to the pool when it has
4239 (scm_printer_apply): Set `revealed' field of print_state to true.
4240 (scm_init_print): Set scm_print_state_vtable.
4241 (print_state_fluid, print_state_fluid_num): Removed.
4243 * throw.h (scm_handle_by_proc_catching_all): New prototype
4244 throw.c (scm_handle_by_proc_catching_all): New function
4246 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4248 * Makefile.in: Regenerated with automake 1.2c.
4250 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4252 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4253 was looping endlessly.
4255 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4257 * strports.c (scm_eval_string): Don't close the port.
4259 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4260 former returns a nice normal integer. (Thanks to Daniel
4263 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4265 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4266 makefile variable as a build parameter called LIBS. The
4267 build-guile program will use this, for the time being.
4268 * Makefile.in: Regenerated.
4270 Thanks to Shiro Kawai:
4271 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4272 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4275 * Makefile.in: Regenerated with automake 1.2a.
4277 * script.c (scm_compile_shell_switches): If we hit the -c or --
4278 arguments, don't set the car of (command-line) to scm_usage_name,
4279 the prettified name of the guile executable; give it the full
4280 path, the way shells usually handle $0.
4282 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4284 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4285 Scheme-level name `array-map' and renamed `serial-array-map' to
4286 `serial-array-map!'.
4288 * backtrace.c: Introduced exception handlers which now enclose
4289 `display-error' and `display-backtrace' so that error reporting
4290 won't get into infinite loops if an error occurs during displaying
4291 of the error. This can very easily happen with user supplied
4292 print call-back routines.
4294 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4296 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4297 the names `serial-array-map' and `array-map' should be removed.)
4299 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4301 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4302 Added #include "objects.h"
4304 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4305 Add #include "feature.h".
4307 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4308 (modinclude_HEADERS): Added objects.h.
4310 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4311 This test is needed at many places in the code and should be
4312 abstracted. (Motivated by the need of this test in libguiletk.)
4314 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4315 (scm_eval_string), load.c (scm_primitive_load,
4316 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4317 Use SCM_EOF_OBJECT_P.
4319 * eval.c (scm_init_eval): Add feature `delay'.
4321 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4323 * scmhob.h: Removed.
4325 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4327 * list.h (SCM_LISTn): New macros. Make list creation in C code
4328 prettier. The idea comes from STk.
4330 * sequences.h, sequences.c, append.h, append.c: Removed. These
4331 files implemented non-R4RS operations which would encourage
4332 non-portable programming style and less easy-to-read code.
4334 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4337 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4338 sequences.h, #include append.h.
4340 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4343 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4345 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4347 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4349 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4351 * eval.c: Added #include "objects.h"
4353 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4356 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4357 adjacent smob numbers.
4359 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4361 * procprop.h: Added declaration of scm_i_inner_name.
4363 * gsubr.c: New global symbol scm_i_inner_name.
4365 * debug.c (scm_procedure_name): Try procedure property
4366 `inner-name' if `name' fails.
4368 * print.c (scm_iprin1): Use scm_macro_name.
4370 * eval.c (scm_m_define): Give names to macros as well; Only the
4371 first top-level definition gives a procedure/macro a name.
4372 Otherwise confusing names can turn up in backtraces.
4373 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4374 `name'; Give names to macros as well.
4376 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4377 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4380 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4382 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4384 (prinmacro): Removed. The code has been moved/merged into print.c
4385 in order to decrease code redundancy. We want macros to print in
4386 a way equivalent to procedures, and it would be silly to duplicate
4387 the required code. (We don't want to maintain two places.)
4388 (macrosmob): Print field is now a NULL pointer.
4390 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4391 scm_macro_transformer): New prototypes.
4392 (scm_tc16_macro): Declared.
4394 * print.c (scm_iprin1): Added code for printing of macros. Macros
4395 are now printed in a way equivalent to procedures.
4397 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4399 * procs.h (scm_closure_p): Added declaration.
4401 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4403 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4404 Shouldn't pass "heap" as the subr name.
4406 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4408 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4409 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4410 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4411 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4412 SCM_BOOL_T. Any non-false value is true.
4414 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4416 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4417 scm_gensym): Added prototypes.
4419 * symbols.c (scm_gensym): New function. This will speed up
4420 certain types of applications (such as macro systems) which
4421 generate lots of symbols.
4423 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4425 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4427 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4429 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4430 specifier, since (2) or (2 . 3) would cause SEGV.
4431 (scm_transpose_array): more argument checking fixes.
4433 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4435 * Makefile.in: Regenerated.
4437 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4439 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4441 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4443 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4445 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4447 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4448 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4451 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4452 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4453 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4454 scm_array_p, scm_array_rank, scm_array_dimensions,
4455 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4456 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4457 scm_array_prototype): Added case scm_tc7_wvect.
4459 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4461 * errno.h: prototype for scm_strerror.
4462 * error.c (scm_strerror): new procedure.
4464 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4466 * list.c (scm_list_append_x): Allow non-pair as last argument.
4467 This is consistent with the R4RS append and is probably the
4468 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4470 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4472 * stime.h: prototype for scm_times.
4473 * stime.c (scm_times): new procedure.
4474 * ioext.c (scm_fseek): if the first argument is a file descriptor
4476 (scm_ftell): if the first argument is a file descriptor call lseek
4478 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
4479 * filesys.c (scm_chmod): if the first argument is a file descriptor,
4481 (scm_chown): if the first argument is a port or file descriptor,
4483 (scm_truncate_file): new procedure.
4484 Add DEFER/ALLOW INTS to a few other procedures.
4485 (scm_fsync): new procedure.
4486 (scm_open_fdes): new procedure.
4487 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
4489 (scm_fcntl): the first argument can now be a file descriptor. The
4490 third argument is now optional.
4492 * posix.c (scm_execl, scm_execlp): make the filename argument
4493 compulsory, since omitting it causes SEGV.
4494 (scm_sync): return unspecified instead of #f.
4495 (scm_execle): new procedure.
4496 (environ_list_to_c): new procedure.
4497 (scm_environ): use environ_list_to_c. disable interrupts.
4498 (scm_convert_exec_args): take pos and subr arguments and
4499 improve error checking.
4501 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4503 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4504 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4505 argument to SCM_ASSERT. Furthermore, the name of the function
4506 should be passed as first argument when signalling
4507 SCM_WNA. (Thanks to Thomas Morgan)
4509 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4510 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4511 dispatches on the number of actual args has a default case
4512 reporting an internal error. This is a vestige from a version
4513 that mallocated a SCM vector to hold the arguments. In the
4514 current version this check is too late: if it ever happens we will
4515 have already overstepped the bounds of the array.
4517 Also, the patch [...] adds a check for too many actual arguments."
4519 mdj: Removed check for "internal programming error".

4670 but that should be much less likely.

4715 DEBUG_EXTENSIONS isn't #defined.

4744 have to do this explicitly. Also, if regexp/basic is supplied, then
4745 turn off REG_EXTENDED.
4746 (scm_init_regex_posix): New regexp/basic symbol.
4747 (REG_BASIC): #define this if it is not already present.

4794 (cwdr_outer_body): New function, to establish the user's handler,
4795 and pass control to cwdr_inner_body.

4807 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4808 the feeling that real thread systems will not need this...
4810 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4812 Try to detect when people are using one version of libguile and a

4826 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4827 1:2. Helps avoid confusion between installed and uninstalled libs.
4829 * scmconfig.h.in: Regenerated. (Needed after June 3 change to

4858 * tag.c (scm_tag): Remove unreachable statement.
4859 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4860 top of the word, it should be unsigned.
4862 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4863 is defined, to avoid warnings; it's only used in the
4864 conflict-checking code. Which might go away anyway.
4865 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4866 conditionals; put the label definition in an #if too, to stifle
4869 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4870 ChangeLog-threads in the distribution.
4871 * Makefile.in: Regenerated.

4918 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4919 supplied. (Change from Tim Pierce.)
4921 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4923 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4924 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4925 default and not `()'. `#f' is the canonical non-value in Scheme,
4928 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4930 * struct.c (struct_printer): New variable that holds a handle on
4931 the Scheme variable *struct-printer*. This variable can be set by
4932 Scheme code to override the printing of structures.
4933 (scm_print_struct): If struct_printer is set, call it. If it is
4934 not set, or returns #f, print the structure in the old fashion.
4935 Include "eval.h" for scm_apply.
4937 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4939 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4940 scm_struct_i_n_words to get the number of fields, not

4943 On the route to fancier struct printing:
4944 * struct.c (scm_print_struct): New function to print a structure.
4945 Include "genio.h" to support it. This function doesn't do
4946 anything interesting right now, but I think it should be here
4948 * struct.h: Include "print.h" and add prototype for
4950 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4951 print structures ourself.

4962 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4965 * posix.c (scm_uname): interpret only negative values as an error.
4966 Solaris normally returns a positive value.
4968 * script.c (scm_compile_shell_switches): if we are not going into
4969 an interactive repl, set scm_mask_ints to zero so that asyncs can
4972 * simpos.c (scm_system): don't ignore/unignore signals around
4975 * posix.c (scm_open_pipe): don't ignore/unignore signals around

4979 done in boot-9.scm instead.
4981 * scmsigs.c, async.c: Major rewriting of signal handling code.
4982 (scm_sigaction): new procedure.
4983 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4985 (scm_raise): return unspecified, throw error on failure.
4987 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4989 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4990 feature, to help boot-9.scm decide whether to import the regex
4993 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4995 * eval.c: Include scmconfig.h at the beginning of the file so that
4996 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
4999 * regex-posix.c: #include "_scm.h" before conditionally #including
5000 <regex.h>; the former defines HAVE_REGCOMP.
5002 * regex-posix.c: #include <regex.h> conditionally, so the file is
5003 CPP'able (for dependency scanning) even on systems that don't have
5006 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5008 Add new R4RS-compliant syntax for keywords.
5009 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5010 regardless of the setting of the `keywords' read option.
5011 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5012 can be re-read no matter what the setting of the `keywords' read
5015 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5017 Add support for POSIX regular expressions.
5019 * regex-posix.c, regex-posix.h: New files. (Some code
5020 is taken liberally from rx/rgx.c in the old Guile dist.)
5022 * init.c: Include regex-posix.h.
5023 (scm_boot_guile_1): Call scm_init_regex_posix.
5025 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5026 Add regex-posix.[ch] sources.
5027 * Makefile.in: Regenerated.
5029 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5030 to do this automatically? It didn't for me, bleh.)
5032 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5034 * fports.c (print_pipe_port): New function.
5035 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5036 latter doesn't even take the right arguments.
5038 * Makefile.am: Increment shared lib revision number. I think
5039 sometimes the uninstalled Guile finds the installed shared lib;
5040 Gord says doing this might help. As things turned out, I can't
5041 say whether it does.
5042 * Makefile.in: Regenerated.
5044 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5045 passing it as the closure argument to scm_boot_guile. (Bill
5048 * ports.c (print_void_port, putc_void_port, puts_void_port,
5049 write_void_port, flush_void_port, getc_void_port, close_void_port,
5050 noop0): Use ANSI prototypes instead of K&R declarations, so the
5051 initialization of void_port_ptob gets aggressively type-checked.
5052 Fix arguments of print_void_port and write_void_port. (Bill

5086 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5088 * script.c (scm_find_executable): Use prototype-style definition
5089 here; apparently it's not quite right to have const in a prototype
5090 and then use a K&R declaration. I wonder if stuff like this will
5091 go away if we compile with -Wrequire-prototypes, or whatever that
5092 is... (Bernard URBAN)
5094 * scmhob.h: New text from Bernard URBAN.
5096 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5098 * script.c: Don't #define const on hpux. Configure takes care of
5099 this. (Thanks to Larry Schwimmer.)
5101 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5102 decide whether to #include <unistd.h>, instead of listing a bunch
5103 of systems. Don't #include stdio twice. Removed dyked-out
5104 definition of scm_find_impl_file.
5106 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5108 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5109 library version info to 1:0.
5110 * Makefile.in: Regenerated.
5112 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

5116 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5117 throw.c: Update copyright years; these files have been worked on
5118 significantly in 1997, but only had copyright years for 1996.
5119 Also, change name of copyright holder on some from Mikael
5120 Djurfeldt to Free Software Foundation; he has signed papers
5121 assigning the changes to the FSF.
5123 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5124 reason not to give the user the option.
5126 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5127 Return #f on end-of-file when scanning table (i.e. when called
5128 with no arguments). Try to catch errors, when we can.
5129 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5131 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5132 external declarations. These are useful.
5134 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5136 * posix.c: don't include <sys/select.h> or define macros for
5137 select, since they were not used in this file.
5139 * filesys.c (scm_select): make the fifth parameter microseconds,
5140 not milliseconds. let the fourth parameter be either a real value
5141 or an integer or #f. The first, second and third arguments can
5142 now be vectors: the type of the corresponding return set will be
5144 (set_element, get_element): new static procedures.
5146 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5148 * strports.c (scm_eval_string): New function.
5149 (scm_eval_0str): Trivially re-implemented in terms of
5151 * strports.h (scm_eval_string): New extern decl.
5153 * net_db.c (h_errno): Add extern decl for this.
5155 * fports.c (local_pclose): New function.
5156 (scm_pipob): Use it in the initializer here.
5159 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5160 Use a meaningful error message when signalling an error. For
5161 this, scm_gethost must check h_errno rather than errno.
5163 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5165 * Makefile.in: Regenerated, using automake-1.1p.
5167 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5169 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5170 not SCM_UNSPECIFIED.
5172 * script.c (scm_compile_shell_switches): don't append (quit) if
5174 (scm_shell): call scm_exit_status and exit on the result of the
5177 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5179 Ensure that shared substrings are handled properly when passed to
5180 a system call or other foreign function. Many thanks to Tim
5182 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5183 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5184 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5185 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
5186 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
5187 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5188 (scm_display_error_message): use RO macros when strings may be RO.
5189 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5190 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5191 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

5195 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
5196 scm_strftime), vports.c (scm_make_soft_port): use
5197 SCM_COERCE_SUBSTR to make sure shared substrings are
5200 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5202 * error.c (scm_error): Add newline to error message.
5204 * init.c (scm_init_standard_ports): Doc fix.
5206 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5208 * dynl-shl.c: Completely replaced with new code from Bernard
5211 * script.c (scm_ice_9_already_loaded): New variable.
5212 (scm_compile_shell_switches): Use it.
5214 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5216 * filesys.c (scm_input_waiting_p): add missing third argument to
5219 * stime.c (scm_localtime): copy the result of localtime before
5220 calling gmtime in case they share a buffer.
5221 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5224 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5226 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5228 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5230 * Makefile.am (check-local): New target, which causes 'make check'
5231 to run gh_test_c and gh_test_repl, with some trivial input.
5232 * Makefile.in: Rgnrtd.
5234 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5236 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5239 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5241 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5242 sure how this was supposed to work.
5243 (scm_async_click): don't send SCM_TICK_SIGNAL.
5244 (scm_init_async): don't initialize %tick-thunk.
5246 * the following change doesn't affect the Scheme interface:
5247 gc-thunk is called at the end of garbage collection. however it's
5248 no longer implemented by pretending it's a signal.
5250 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5251 system async corresponding to scm_gc_thunk.
5252 * async.h: declare scm_gc_async.
5253 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5254 gc-thunk directly, instead of going through a signal handler.
5255 (scm_gc_async): new variable, points to the GC system-async.
5256 (scm_init_async): save the GC async as scm_gc_async instead
5257 of using system_signal_asyncs.
5258 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5260 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
5262 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
5263 Don't screw up if we're interrupted.
5264 * Makefile.in: Regeneradet.
5266 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5268 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5270 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5271 we're not using AM_INIT_GUILE_MODULE any more.
5272 * Makefile.in: Reneregated.
5274 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5276 Functions for finding variable bindings, grace à Tim Pierce.
5277 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5278 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5280 Get 'make dist' to work again.
5281 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5282 * Makefile.in: Regenerated, like a surry without a fringe on top.
5284 Changes for reduced Guile distribution: one configure script,
5286 * configure.in, configure: Removed.
5287 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5288 real configure script lives.
5289 * Makefile.in, scmconfig.h.in: Regenerated.
5291 * init.c: #include "script.h", to get prototype for script.c's
5294 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5296 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5297 scm_must_malloc, not raw malloc.
5299 * script.c (scm_compile_shell_switches): Dyke out debugging output
5302 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5304 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5306 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5307 system has them. Hope this is safe. Previously
5308 sys/timeb.h was included if HAVE_FTIME was defined or if
5309 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5310 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5312 * ioext.c (scm_setfileno): add missing third argument to
5313 scm_misc_error call.
5315 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5317 * eq.c (scm_equal_p): Correctly compare strings of different
5318 varieties. (Thanks to Tim Pierce.)
5320 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5322 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5323 #! block comment must occur on a line all by itself.
5325 Move most of the guts of shell command processing into libguile,
5326 so guile.c can be very small (and eventuallly auto-generated. (I
5327 mean, generated mechanically, not self-generated. Hmm.))
5328 * guile.c, script.c, script.h: New source files.
5329 * init.c (scm_boot_guile_1): Call scm_init_script.
5330 * libguile.h: #include "script.h".
5331 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5332 targets, for new executable.
5333 (libguile_la_SOURCES): Mention script.c.
5334 (modinclude_HEADERS): Add script.h.
5335 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5336 not dynamic linking is enabled. This is because we're generating
5337 executables now. Move CY_AC_WITH_THREADS call after those, so the
5338 values of cy_cv_threads_libs captures the libs chosen above.
5339 * Makefile.in, configure, aclocal.m4: Regenerated.
5341 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5342 We don't maintain this interface any more, and it just confuses
5345 * alloca.c: #include <scmconfig.h>, not <config.h>.
5346 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5347 it'll get included in disties.
5349 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5351 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5352 be distributed, because they confuse people.
5353 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5355 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5357 * configure.in: check for presence of gethostent (not present on
5358 OpenBSD by default).
5359 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5360 * configure, scmconfig.h.in: Regenerated.
5362 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5364 * backtrace.c (scm_backtrace): Split message string across
5365 newlines properly. GCC is more tolerant of this than other
5368 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5370 Merge threads directory into libguile.
5371 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5372 threads.h: New source files.
5373 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
5374 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5376 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5377 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5378 coop-threads.c.cygnus, coop-threads.h.cygnus.
5379 * configure.in: If we're using threads, include threads.o in
5381 * _scm.h, libguile.h: threads.h lives in this directory now.
5382 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5383 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5384 currently used, but brought along for information's sake.
5385 * ChangeLog-threads: log from old 'threads' directory.
5386 * Makefile.in, configure: Rebuilt.
5388 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5390 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5393 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5395 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5397 Merge GH interface library into libguile.
5398 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5399 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5400 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5401 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5403 (EXTRA_libguile_la_SOURCES): ... here.
5404 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5405 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5406 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5407 New variables, describing how to build the gh test programs.
5408 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5409 build the test programs, and we probably should have been linking
5410 libguile.la against them all along, to support AIX shared libs.
5411 Add cflags for threads to CFLAGS; add libs for threads to new
5412 variable THREAD_LIBS, used in Makefile.am.
5413 * ChangeLog-gh: log from old `gh' subdirectory.
5414 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5416 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5418 * acconfig.h: Undo change of Apr 9; including the definition of
5419 PACKAGE in the guile headers conflicts with applications' own
5421 * scmconfig.h.in: Regenerated.
5423 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
5425 * filesys.c (scm_fcntl): New function from Roland McGrath.
5426 (scm_init_filesys): New symbols for use with fcntl.

5434 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5435 have S_IFSOCK. This is the case under Ultrix.
5437 * posix.c (scm_status_exit_val, scm_status_exit_val,
5438 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5439 Ultrix versions of WIFSTOPPED, etc., which assume that their
5440 arguments are lvalues (hmm).
5442 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5444 * eval.c: Doc fixes.
5446 * throw.c: Doc fixes; rearranged.
5448 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5450 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5452 * acconfig.h: Added entry for PACKAGE.
5453 * scmconfig.h.in: Regenerated.
5455 Changes to work with automake-1.1n, which has better libtool support.
5456 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5457 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5459 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5461 * Makefile.in: Rebuild.
5463 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5465 * stime.c (scm_mktime): take an optional zone argument.
5466 (scm_localtime): check putenv return value.

5470 (bdtime2c, setzone, restorezone): new static procedures.
5471 (scm_mktime, scm_strftime): use them.

5473 filltime for return value.
5474 (filltime): convert NULL zname to #f.
5475 (scm_strptime): return a count of characters consumed, not
5476 the remaining string.
5478 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5480 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

5483 Uncomment localtime and mktime.
5485 * configure.in: add AC_STRUCT_TIMEZONE.

5489 * stime.c (scm_init_stime): don't define ticks/sec.
5490 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5491 return value problem and is still portable.)
5493 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5495 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5496 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5497 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5498 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5499 cpp_err_symbols.c): Corresponding changes.
5500 * Makefile.in: Regenerated.
5502 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5504 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5505 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5506 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5507 * putenv.c: new file, from sh-utils 1.12.
5509 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5510 since allocation isn't for Scheme objects.
5511 (scm_putenv): copy strings before placing in the environment.
5513 * stime.c (scm_current_time): throw an error if time returns -1,
5514 instead of returning #f.
5515 (scm_get_internal_real_time, scm_get_internal_real_time): use
5516 scm_long2num for return value instead of SCM_MAKINUM.
5518 * stime.h: prototypes updated.
5520 * stime.c (scm_time_in_msec): apparently unused, deleted.
5522 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5524 * configure.in: check for gettimeofday.
5526 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5527 which may be more usefully portable than a gettimeofday interface.
5529 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5531 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5533 * Makefile.in: Regenerated.
5535 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5537 * stime.c (filltime): recovered static procedure.
5538 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5541 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5542 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5544 * posix.c (scm_mknod): split the mode argument into type and perms
5545 arguments, like the extra fields returned by stat.
5547 * fports.c (scm_pipob): set the close, free and print procedures.
5548 (scm_close_pipe): new procedure.
5550 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5551 define them in boot-9.scm
5553 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5555 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5556 wan't defined. Don't include fd.h.
5558 * Previously fd.h was regenerated whenever configure was run,
5559 forcing a couple of files to be recompiled.
5561 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5562 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5563 Check for _fileno as well as _file.
5565 * ioext.c: don't fd.h.
5566 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5569 * Change the stratigy for getting information about errno
5570 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5571 generating lists of symbols during the build process, which will
5572 not always work, include comprehensive lists in the distribution.
5573 To help keep the lists up to date, the "check_signals" and
5574 "check_errnos" make targets can be used.
5576 * configure.in: don't check for a command to extract errno codes.
5577 * Makefile.am: update file lists, remove errnos.list and errnos.c
5578 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5579 check_errnos targets.
5580 (CLEANFILES): remove errnos.c and errnos.list, add
5581 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new

5587 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5588 * error.c (scm_init_error): #include cpp_err_symbols instead of
5590 * posix.c (scm_init_posix): don't intern signal symbols. #include
5593 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5595 * strop.c (scm_i_index): allow the lower bound to be equal to the
5596 length of the string, so a null string doesn't always give an error.
5598 * posix.h: new prototypes.
5599 * posix.c (scm_status_exit_val, scm_status_term_sig,
5600 scm_status_stop_sig): new functions, as in scsh. They break down
5601 process status values as returned by waitpid.
5603 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5605 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5606 configure doesn't know about it.
5608 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5610 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5612 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5613 which defines C variables with global linkage.
5615 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5617 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5620 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5622 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5623 has time to check why this doesn't work well with continuations.
5625 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5627 * Fix shell syntax error; some shells won't tolerate
5628 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5630 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5632 * posix.c (scm_uname): throw an error if uname fails instead
5635 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5637 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5640 * async.c (scm_ints_disabled): definition moved from error.c.
5642 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5644 * acconfig.h: Removed PACKAGE.
5646 * scmconfig.h.in: Regenerated.
5648 * snarf.h: g++ says it's non-portable not to specify the first
5649 argument in a varargs declaration. I introduced the first
5650 argument by using preprocessor conditionals.
5652 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5654 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5655 (scm_freopen): use RO string macros for filename and modes.
5656 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5658 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5659 (scm_mknod): use RO string macros for path.
5661 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5662 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5664 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5665 use SCM_ROSTRINGP and SCM_ROCHARS.
5667 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5669 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5672 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5673 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5674 support for byte vectors.
5676 * print.c (scm_iprin1): Limit number of vector elements printed
5677 according to pstate->length.
5679 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5681 * backtrace.c (scm_display_error_message): don't segv if message
5684 * error.h: prototype for scm_error_scm.
5686 * error.c (scm_error_scm): new procedure, reimplements scm-error
5687 in C and uses scm_error.
5689 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5691 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5692 pointer to the Scheme variable read-hash-procedures and intern it
5693 in scm_init_read. Modify scm_read_hash_extend and
5694 scm_get_hash_procedure to use the pointer.
5696 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5698 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5699 (SCM_KEYWORD_STYLE): defined.
5701 * read.c (scm_read_opts): add a keywords option. This isn't a
5702 boolean option, in case someone wants to add support for DSSSL
5704 Setup scm_keyword_prefix symbol.
5705 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5707 I've left keyword support disabled by default, since it doesn't
5708 seem to break the module system and it gives R4RS standard behaviour.
5709 It can be reactivated with (read-set! keywords 'prefix).
5711 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5713 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5714 before constructing arbiter.
5716 * eval.c (scm_m_define): Bugfix: Check that the object is a
5717 closure before setting the procedure property!
5719 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5721 * ports.c: Removed `ungetc-char-ready?'.
5723 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5725 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5726 (idea from Mikael: make it a pair so scm_permanent object only
5728 (scm_read_hash_extend): don't call scm_permanent_object.
5729 (ideas from Mikael): if chr is already in the list, replace its
5730 procedure instead of appending it again. If proc is #f, remove
5732 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5734 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5736 * gdbint.c (gdb_read): update scm_lreadr usage.
5738 * load.h: update prototypes.
5740 * load.c (scm_primitive_load, scm_read_and_eval_x,
5741 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5743 * read.h: add prototype for scm_read_hash_extend. Change args for
5746 * read.c (scm_read_hash_procedures): new variable.
5747 (scm_read_hash_extend): new procedure.
5748 (scm_get_hash_procedure): new procedure.
5749 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5750 for extended # processing.
5751 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5752 scm_read_token): remove case_i, sharp arguments. Change callers.
5754 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5756 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5757 (SCM_CASE_INSENSITIVE_P): define.
5759 * read.c: add case-insensitive option to scm_read_opts.
5760 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5761 to determine whether to convert symbol case.
5762 (default_case_i): definition removed.
5763 * read.c (scm_read_token): if case_i, downcase ic before doing
5766 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5768 * configure.in: Added configuration option `guile-debug'.
5769 Configure with --enable-guile-debug if you want a bunch of extra
5770 functions used for debugging when developing Guile.
5772 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5774 * procs.c (make-cclo): New undocumented debugging procedure: Make
5775 compiled closure with internal procedure PROC and length LENGTH.
5776 Only compiled if GUILE_DEBUG is defined.
5778 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5780 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5782 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5784 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5785 with 3 or more args internally to the evaluator.
5787 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5789 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5790 with 3 or more args internally to the evaluator. This is mainly
5791 because we don't want to pass entry and exit points of the
5792 debug support twice, but it also seems to increase the speed of
5793 the evaluator for such calls (e. g. (+ 1 2 3)).
5795 * backtrace.c (scm_display_application): New procedure:
5796 display-application; Set fancy printing parameters individually
5797 for different types of display (backtrace, error, application).
5798 (These should of course be customizable!)
5800 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5801 clear the CHECK-flags.
5803 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5805 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5807 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5809 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5810 from pairs with a GLOC in the car.
5812 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5813 otherwise `symbol-hash' will behave badly.
5814 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5815 we get segmentation fault!
5817 * symbols.c: Added #include "weaks.h". New functions:
5818 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5819 moved to an extraneous library when we split libguile.)
5821 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5823 * filesys.c (scm_stat): stat now takes fport arguments too as
5824 documented in the manual.
5826 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5828 * debug.c (scm_single_step): Bugfix: Call continuation with
5829 scm_call_continuation instead of throwing to it.
5831 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5833 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5834 argument wasn't declared to be optional.
5836 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5838 * stime.c (scm_init_stime): Add feature "current-time".
5840 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5842 * throw.h: prototype for scm_exit_status.
5843 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5844 args to derive an exit status. Allows (quit) to work from a
5846 (scm_exit_status): new function.
5849 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5851 * eval.c (scm_deval): Removed some old code.
5852 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5854 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5857 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5860 * procs.c: Introduce the existent C function scm_thunk_p at the
5861 Scheme level as well.
5863 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5865 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5866 used from C to easily lookup the value of a symbol in the current
5869 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5871 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5872 scm_init_unif in this file. This will also fix a previous problem
5875 * configure.in: Added AM_MAINTAINER_MODE
5877 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5879 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5882 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5884 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5885 source files that are not always included in libguile but should
5886 have their dependencies calculated by automake. This variable is
5887 recognized by automake, no further magic is needed.
5888 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5889 to deal exclusively with *.lo files, as it seems. The *.o files
5890 are built automatically when the corresponding *.lo file gets
5893 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5895 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5898 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5900 * unif.c (scm_array_set_x): minor change to argument error checking.
5902 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5904 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5905 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5906 They should only be included in the library at configure.in's
5908 (libguile_la_LDADD): Include the appropriate .lo files here.
5909 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5910 so we know when to build them (and their .lo bretheren).
5911 * configure.in (LIBLOBJS): New substituted variable. We let
5912 configure decide which .o files to include in LIBOBJS, and then
5913 put the corresponding list of .lo files in LIBLOBJS. The latter
5914 is what we pass to libtool.
5915 * Makefile.in, configure: regenerated.
5917 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5919 * symbols.c (scm_sysintern0): New function. Contains the core of
5920 old scm_sysintern but doesn't take a second value argument.
5921 (scm_sysintern): Now uses scm_sysintern0.
5922 (scm_sysintern_no_module_lookup): Renamed to
5923 scm_sysintern0_no_module_lookup and doesn't take a second value
5924 argument any longer.
5926 * symbols.h (scm_sysintern0: Added declaration.
5928 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5929 scm_sysintern when interning option keys. Otherwise we risk
5930 destroying the values of already interned variables.
5932 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5933 scheme-level boolean (use SCM_NFALSEP).
5935 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5937 (scm_backtrace): New function. (C version of old function from
5938 boot-9.scm) Motivation: Make it possible to display backtraces
5939 without depending on boot-9.scm. (I'm uncertain if this
5940 motivation is good enough...)
5942 * root.h (scm_root_state): Add member the_last_stack_var.
5943 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5945 * root.c (mark_root): Mark scm_the_last_stack_var.
5947 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5950 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5952 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5953 1. mark_lazy_catch didn't mark the smob.
5954 2. Both functions above have standard variants:
5955 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5956 free_lazy_catch --> scm_free0.
5958 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5960 * throw.c (scm_internal_lazy_catch): New function.
5961 (scm_lazy_catch): Rewritten to use it.
5962 (scm_ithrow): Handle the new lazy catch representation.
5963 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5964 that doesn't have a jmpbuf is a lazy catch clause.
5965 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5966 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5967 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5969 (scm_init_throw): Register the new lazy-catch smob type.
5970 * throw.h (scm_internal_lazy_catch): decl for new function.
5972 * throw.c (scm_internal_catch): Doc fixes.
5974 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5975 configure.in. Including this might cause problems if applications
5976 that link against libguile include their own copies of alloca, but
5977 if they're using autoconf, they should be adding libguile to LIBS
5978 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5979 the copy in libguile, and things will be okay. (I think.)
5981 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5983 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5985 strop.h: move prototypes too.
5987 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5989 * posix.c (scm_init_posix): don't intern EINTR since it's now done
5992 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
5993 etc. I deleted them from filesys.c long ago, but didn't
5994 notice they were here too (although ineffective since
5995 sys/stat.h wasn't included).
5997 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
5999 * eval.c: Don't define alloca in GCC case. gcc will automatically
6000 use __builtin_alloca if appropriate.
6002 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6004 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6005 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6006 that values of automatic variables are preserved. See comments
6007 for safe_setjmp for details.
6009 Change from Thomas Morgan:
6010 * variable.c: Include eq.h.
6011 (var_equal): New function.
6012 (variable_smob): Use var_equal as the discriminator for variables.
6014 * throw.c (s_throw): Remove extraneous declaration.
6016 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6017 * eval.c: Add necessary CPP cruft to support that.
6018 * configure, Makefile.in, scmconfig.h.in: regenerated.
6020 Change from Thomas Morgan:
6021 * procprop.c (scm_procedure_properties): Convert the Scheme
6022 boolean returned by scm_procedure_p into a C boolean before using
6023 it as a condition for SCM_ASSERT.
6024 (scm_procedure_property): Likewise.
6026 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6027 indications of Unixness.
6030 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6032 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6034 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6036 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6037 "unknown # object" error messages.
6039 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6040 (scm_i_index) and declare it static. Add a 'direction' argument
6041 to indicate what way the search should go.
6042 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6044 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6045 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6047 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6049 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6051 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6052 to avoid clash with various scsh forks.
6054 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6056 The following two changes (ramap.c, throw.c) are motivated by the
6057 apparent unportability of forward declarations of static arrays of
6058 the form `static foo bar[];'.
6060 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6061 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6063 * throw.c (scm_throw): Moved above scm_ithrow.
6065 * options.h: Removed the extern declarations of scm_yes_sym and
6066 scm_no_sym since these are static.
6068 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6070 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6072 * Makefile.am: remove AWK=@AWK@.
6073 Add a rule for generating errnos.list.
6074 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6076 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6077 don't extract errnos, just set a variable (avoids the
6078 need to recompile error.c just because configure is run.)
6080 * unif.h: update prototypes.
6081 * unif.c (scm_uniform_array_read,write): change the offset and
6082 length arguments to start and end, for consistency.
6084 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6086 * ioext.h: update prototypes.
6087 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6088 scm_read_line_x, it's a more general procedure using an
6089 interface from scsh. read-line and read-line! are now defined
6091 Note that the new read-line trims the terminator
6092 by default, previously it was appended to the returned string. An
6093 optional argument specifies how to process the terminator (scsh
6094 compatible). For the old behaviour: (read-line port 'concat).
6095 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6096 returns a pair, but is converted to multiple values if the scsh
6099 socket.h: update prototypes.
6100 * socket.c (scm_recvfrom): for consistency with other procedures,
6101 take start and end as separate optional arguments.
6102 (scm_recv, scm_recvfrom): don't allow the second argument
6103 to be a size, only a buffer. Change the scheme names to
6104 recv! and recvfrom!. Don't return the buffer.
6106 * ioext.h, posix.h: move prototypes too.
6107 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6108 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6109 "read.h" and "unif.h".
6110 * ioext.c: include "chars.h"
6112 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6114 * dynl.c: The dynamic linking and module registration functions
6115 are now defined even when dynamic linking is not available for the
6116 host system. Some of their functionality can be done without
6117 dynamic linking; when it's really needed, they throw errors.
6119 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6121 * configure.in: Only define DYNAMIC_LINKING when one of the system
6122 dependent functions is detected.
6123 * dynl.c (scm_dynamic_func): New function to get the address of a
6124 function in a dynamic object.
6125 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6126 produced by scm_dynamic_func as the thing to call.
6128 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6130 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6131 (scm_register_module_xxx, scm_registered_modules,
6132 scm_clear_registered_modules): New functions.
6134 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6136 * symbols.c (scm_sysintern): Renamed to
6137 scm_sysintern_no_module_lookup.
6138 (scm_sysintern): New function to take the place of the old
6139 scm_sysintern. It uses the current toplevel lookup closure to give
6140 the symbol its value. This is a temporary hack to put packages
6141 like gtcltk into their own module.
6142 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6143 us whether `scm_top_level_lookup_closure_var' has been initialized
6145 * eval.c (scm_init_eval): Set it.
6147 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6149 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6150 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6152 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6154 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6155 scm_sys_dup): deleted: FD capability will be added to other
6157 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6158 scm_fd_free, fd_smob, scm_intern_fd.
6159 (scm_open): renamed from scm_sys_open. Return a port instead of
6160 an FD object. Make the mode argument optional.
6161 (scm_sys_create): deleted, it's just a special case of open.
6162 (scm_init_filesys): move interning of constants O_CREAT etc.,
6163 here (were previously using SCM_CONST_LONG macro).
6164 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6166 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6167 include "fports.h" and <stdio.h>
6168 (scm_stat, scm_select): don't support FD objects.
6170 * error.h: adjust scm_syserror_msg prototype.
6171 * error.c (scm_syserror_msg): take an extra argument for errno.
6172 Using the global value didn't always work, since it could be
6173 reset by procedure calls in the message or args arguments.
6175 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6176 I don't understand why the check was there (and what about the
6179 * strop.c (scm_string_copy): allow shared substrings to be copied.
6181 * unif.h: corresponding change to prototypes.
6182 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6183 recognize two new optional arguments: offset and length. Allow
6184 the port argument to be an integer (file descriptor, for scsh).
6185 Include <unistd.h> for "read" prototype.
6187 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6189 * socket.c: don't include filesys.h.
6191 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6193 * Makefile.am: add AWK=@AWK@ (?)
6195 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6197 Add a rule to generate errnos.c from errnos.
6198 * error.c (scm_init_error): include errnos.c.
6199 * errnos_cnvt.awk: new file, converts the list of errno codes to
6201 * errnos_get.c: new file.
6202 * errnos.default: new file, contains errnos to try if they can't
6203 be extracted from errno.h.
6204 * configure.in: if using GCC, try and extract errno codes from
6208 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6210 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6211 * Makefile.am: Made libguile into a libtool library.
6212 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6213 Set libtool_libs to indicate that libguile is a libtool library.
6214 See guile/ChangeLog for details.
6215 * .cvsignore: ignore "*.lo", the libtool library objects.
6217 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6219 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6220 use htons in getservbyport argument.
6222 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6224 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6225 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6228 * objprop.c (scm_object_property): No need to take the CDR of the
6229 value returned by scm_object_properties, since Aug 20 change.
6231 * configure.in: When checking for struct linger, #include
6232 <sys/types.h> as well as <sys/socket.h>. I've never known
6233 <sys/types.h> to cause any portability problems, and Solaris's
6234 <sys/socket.h> needs it.
6235 * configure: Rebuilt.
6237 I think the Sun compiler has chosen a perverse way to interpret
6238 ANSI declarations combined with K&R definitions. We'll
6239 appease it a little bit. But when it invades France, we fight.
6240 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6241 * print.h (scm_iprlist): Here too.
6242 * numbers.c (scm_divbigdig): Change definition to match
6243 declaration in numbers.h.
6244 * unif.c (scm_makflo): Change definition to match declaration in
6247 * init.c (scm_boot_guile): Don't return the value of
6248 scm_boot_guile_1. This function doesn't return a value;
6249 scm_boot_guile_1 doesn't return a value (or return at all).
6251 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6254 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6255 compile. I have a feeling this function is a bad idea anyway ---
6256 one should always test for features, not systems.
6258 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6259 semicolons. Only pure luck kept this from being noticed earlier.
6261 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6263 * socket.c (scm_recvfrom): Added missing semicolon.
6265 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6267 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6268 the buffer and start and end positions for scsh networking
6271 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6273 * configure.in: Revert previous change to this file; the problem
6274 is due to transient automake weirdness.
6275 * configure: Rebuilt.
6277 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6278 PLUGIN/guile.libs. configure generates the latter from the former.
6279 * Makefile.in: Rebuilt.
6281 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6282 need this if we install scripts, like guile-snarf.
6283 * configure: Rebuilt.
6285 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6287 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6289 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6291 * socket.c (scm_addr_vector): fix faulty scm_listify.
6293 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6295 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6296 style block comment is no longer considered an error.
6298 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6300 * PLUGIN/guile.libs.in: New file.
6301 * PLUGIN/guile.libs: Removed from repository.
6302 * configure.in: Create PLUGIN/guile.libs from
6303 PLUGIN/guile.libs.in. This is for including additonal libraries
6304 needed for dynamic linking.
6305 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6306 instead of PLUGIN/guile.libs.
6308 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6310 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6312 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6313 occurrences of the given element from the list, not just the
6314 first. This is how the Emacs Lisp functions behave, how the
6315 analogous Common Lisp functions behave, and (I believe) how the
6316 older Maclisp functions worked. I realize that this change may
6317 break code, but it seemed better to break it before the Guile
6320 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6321 Their prototypes were already present in gc.h, but they weren't
6323 (scm_init_storage): Initialize scm_protects.
6324 * root.c (scm_protects): New element of scm_sys_protects.
6326 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6328 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6330 * libguile.h: Added #include "libguile/net_db.h".
6332 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6333 30 change. That file is only meant for communication between the
6334 configuration process and load.c. If code linked against libguile
6335 wants to get at the paths mentioned in libpath.h, it can call
6336 functions declared in load.h.
6338 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6340 * libguile.h: Removed #include "libguile/fdsocket.h"
6342 * net_db.c: Added #include <sys/socket.h>.
6344 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6346 * filesys.c (scm_input_waiting_p): use select in preference to
6347 FIONREAD, since the latter doesn't detect EOF.
6348 Throw error if neither select nor FIONREAD available.
6350 * socket.c (scm_connect): take a port, not a fd object.
6351 (scm_fill_sockaddr): throw an error if fam is not recognised.
6352 (scm_bind): use scm_fill_sockaddr.
6353 (scm_listen): take a port, not a fd object.
6354 (scm_accept): take and return a port. return #f in the car if
6355 address can't be got
6356 (scm_sock_fd_to_port): new procedure.
6357 (scm_socket): use scm_sock_fd_to_port.
6358 (scm_addr_vector): throw error if unrecognised address type.
6359 take an extra argument with the calling procedure name.
6360 (scm_getsockname): take a port. return #f if address can't be got.
6361 (scm_getpeername): take a port. return #f if address can't be got.
6362 (scm_recvfrom): take a port. return #f for address component if can't
6364 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6365 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6367 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6369 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6370 use separate data pointers, to allow them to be designed
6371 independently and reused.
6372 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6373 Renamed from catch_body, catch_handler, and uncaught_throw; made
6375 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6377 (scm_catch): Use the above.
6378 (scm_throw): Don't bother printing a message for an uncaught
6379 throw; we establish a default handler in init.
6380 * throw.h (scm_internal_catch): Prototype updated.
6381 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6383 (struct scm_body_thunk_data): New structure, used as data
6384 argument to scm_body_thunk.
6385 * init.c (struct main_func_closure): New structure, packaging up
6386 the data to pass to the user's main function.
6387 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6388 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6389 scm_internal_catch to establish a catch-all handler, using
6390 scm_handle_by_message. This replaces the special-case code in
6392 (invoke_main_func): Body function for scm_internal_catch; invoke
6393 the user's main function, using the main_func_closure pointer to
6394 decide what to pass it.
6395 * root.c (struct cwdr_body_data): Remove handler_proc member.
6396 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6397 (cwdr_handler): Removed.
6399 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6401 * socket.h (SCM_P): update bind prototype.
6402 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6403 include "feature.h".
6404 (scm_socket): return a port, not a file descriptor object.
6405 include "fports.h" and <unistd.h>
6406 (scm_bind): take a port, not a file descriptor object.
6407 take an extra argument for address args.
6409 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6410 INADDR_NONE, INADDR_LOOPBACK.
6412 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6414 * init.c: include net_db.h and not fdsocket.h.
6415 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6417 * Makefile.am: corresponding changes.
6418 * socket.h: renamed from fdsocket.h, fix names.
6419 * net_db.h: renamed from socket.h, fix names.
6420 * socket.c: renamed from fdsocket.c.
6421 remove _sys from procedure names.
6422 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6423 add "socket" to features list.
6424 * net_db.c: renamed from socket.c.
6425 remove _sys from procedure names.
6426 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6427 add "net-db" to features list.
6428 include "net_db.h". don't include <sys/socket.h> or
6431 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6433 * tags.h (scm_tags): Removed comma at end of last enumerator.
6435 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6437 Don't use GCC extensions to allocate space for debugging frames.
6438 (Here he goes again! Why do we put up with this?!)
6439 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6440 an scm_debug_info structure, not an in-line array of them. Add
6441 'info' member, to say how many vect elements we've used, for eval
6443 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6444 a new variable debug_info_end to mark the end of vect, instead of
6445 the address of the 'info' pointer itself.
6446 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6447 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6448 (SCM_APPLY): Explicitly allocate space for debug.vect.
6449 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6450 * stacks.c: Adjusted for new debug frame structure.
6451 (RELOC_INFO, RELOC_FRAME): New macros.
6452 (stack_depth, read_frames): Use them, and new scm_debug_frame
6453 element 'info', instead of magically knowing that eval frames have
6454 an info pointer sitting after vect.
6455 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6457 (scm_init_stacks): Formatting tweaks.
6459 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6461 Give GCC more control flow information, so it can be sure that
6462 variables aren't used uninitialized.
6463 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6464 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6465 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6466 scm_misc_error): Tell GCC that these functions never return.
6467 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6468 out the field type, call abort if SCM_ASSERT returns, to placate
6470 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6471 scm_wta ever returns. We can't handle this case anyway, and this
6472 gives the optimizer more information.
6473 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6474 scm_wta ever returns.
6476 In some cases, the code is fine, but GCC isn't smart enough to
6477 figure that out; this usually happens when one variable is only
6478 initialized and used when a particular condition holds true, and
6479 we know that condition will never change within a given invocation
6480 of the function. In this case, we simply initialize the variables
6481 to placate the compiler, hopefully to a value which will cause a
6482 crash if it is ever actually used.
6483 * print.c (scm_iprin1): Initialize mw_pos.
6484 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6485 * throw.c (scm_ithrow): Initialize dynpair.
6486 * unif.c (scm_uniform_vector_ref): Initialize cra.
6487 * struct.c (init_struct): Initialize prot.
6488 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6490 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6491 if EXPR contains no expressions.
6493 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6495 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6496 cause an infinite loop (???). So much for the algebraic
6497 equivalency of variable-sized arrays and alloca...
6499 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6501 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6502 a SCM boolean, not a C boolean.
6504 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6506 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6507 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6508 rules for raising scm_mtrigger. Previously, unfortunate but not
6509 unlikely circumstances could result in almost constant invokation
6510 of the gc. Now, this situations should be less likely, but they
6511 are not prevented completely.
6513 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6515 * numbers.c (scm_fuck): Procedure removed; looks like old test
6517 * numbers.h: Prototype removed.
6519 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6521 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6522 array to a pointer, to match my Nov 21 change in eval.c.
6524 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6526 * libguile.h: Added #include "libguile/backtrace.h", #include
6527 "libguile/stacks.h".
6529 * strings.c (scm_string scm_make_string scm_string_ref
6530 scm_string_set_x scm_string_equal_p scm_string_append):
6531 Bugfix according to scm patch from Aubrey Jaffer:
6532 Corrected long-standing
6533 (not (eqv? (integer->char 128)
6534 (string-ref (make-string 1 (integer->char 128)) 0)))
6535 bug found by John Kozak <jk@noontide.demon.co.uk>.
6537 * strports.c, strports.h: Make scm_eval_0str return the value of
6538 the last expression evaluated (previously, it returned void).
6540 * strports.c, strports.h: New function: scm_read_0str. Does what
6543 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6545 * simpos.c (scm_getenv): return #f if string can't be found in the
6546 environment instead of throwing an exception, for compatibility
6547 with numerous other systems.
6549 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6551 * Makefile.am (.c.x): Use guile-snarf.
6552 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6554 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6556 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6558 * backtrace.c (scm_display_error_message): Made non-static, and
6559 renamed from display_error_message.
6560 * backtrace.h (scm_display_error_message): Added extern decl.
6561 * throw.c (uncaught_throw): Use it to display the error message.
6563 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6565 * inet_aton.c: Use #if 0, not #ifdef 0.
6567 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6569 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6570 to convert the returned value.
6571 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6572 the offset argument.
6574 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6576 Add new interface to catch/throw, usable from C as well as
6578 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6579 (scm_internal_catch): New function, replaces...
6580 (scm_catch_apply): Deleted.
6581 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6582 mechanism which is a bit more code, but can be used nicely from C
6583 and implement the Scheme semantics as well.
6584 (scm_internal_catch): This is the replacement; it's named after
6585 the analogous function in Emacs.
6586 (scm_catch): Reimplemented in terms of the above.
6587 (struct catch_body_data, catch_body, catch_handler): New
6588 functions, used by scm_catch.
6589 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6590 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6591 support for new cwdr.
6593 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6596 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6598 * acconfig.h: Added DYNAMIC_LINKING symbol.
6599 * configure.in: Add option and checks for dynamic linking.
6600 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6601 dynl.h: New files for dynamic linking support.
6602 * Makefile.am (libguile_a_SOURCES):
6604 (modinclude_HEADERS): Added "dynl.h".
6605 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6607 * init.c (scm_boot_guile_1): Call
6608 scm_init_dynamic_linking to initialize dynamic linking support.
6610 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6612 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6613 (as we Schemers say). It needs to be global, so that I can tweak
6614 it for the proper operation of unexec.
6615 (scm_boot_guile_1_live): New variable, see above.
6617 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6619 * guile-snarf.sh: Removed.
6620 * PLUGIN/guile.libs: Added dependency for -lm.
6621 * acinclude.m4: Renamed from aclocal.m4.
6622 * PLUGIN/greet: Removed.
6623 * Makefile.am, aclocal.m4: New files.
6624 * configure.in: Updated for Automake.
6626 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6628 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6629 and not top_level_lookup_thunk_var.
6631 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6633 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6635 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6637 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6638 Scheme function, instead of syntax. Single argument is now a
6641 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6643 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6644 scm_ra_divide): Properly terminate statements passed as arguments
6645 to IVDEP macros. (Thanks to Bernard Urban.)
6647 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6648 with non-constant sizes. (Thanks to Bernard Urban.)
6650 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6652 It's an "eval closure", not an "eval thunk." A thunk is a
6653 function of no arguments.
6654 * root.h (struct scm_root_state): Renamed
6655 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6656 (scm_top_level_lookup_closure_var): Renamed from
6657 scm_top_level_lookup_thunk_var.
6658 * root.c (mark_root): Uses changed.
6659 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6660 * init.c (scm_start_stack): Uses changed.
6661 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6662 Change scheme-visible name to *top-level-lookup-closure* from
6663 *top-level-lookup-thunk*.
6665 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6667 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6668 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6670 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6672 * gc.c (struct scm_heap_seg_data): Doc fixes.
6674 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6675 sweeping. Then, prepend each segment's free cells to its
6676 freelist, rather than wiping out the old value. (Thanks to Marius
6679 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6680 scm_check_freelist, scm_debug_newcell): New functions and
6681 variables, for debugging freelist problems.
6682 * pairs.h (SCM_NEWCELL): New debugging version added.
6683 * gc.h (scm_debug_newcell): Added extern declaration, used by
6684 debugging version of SCM_NEWCELL.
6686 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6688 On some systems <libc.h> conflicts with <unistd.h>, and should not
6689 be #included at all.
6690 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6691 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6692 * configure.in: Call it.
6693 * posix.c, filesys.c: Use its results to decide whether or not to
6695 * configure, scmconfig.h.in: Rebuilt with autoconf and
6698 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6700 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6701 pointer to the stdio stream before calling scm_setbuf0, so the
6702 latter will be able to retrieve it. I'm surprised this didn't
6703 segfault earlier. (Thanks to Christopher Lee.)
6705 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6707 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6710 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6712 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6713 number of stack narrowing specifier pairs. The first specifier in
6714 a pair controls inner border, the second the outer border. A
6715 number means cut that number of frames, a procedure object means
6716 cut until that object is found in operator position in a frame.
6718 * root.c (cwdr): Bugfix.
6720 * read.c: Recording of positions disabled by default.
6722 * procs.c (scm_closure_p): New function.
6724 * posix.c (scm_tmpnam): New function.
6726 * load.c: Added #include "throw.h".
6727 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6730 * load.c, load.h (scm_read_and_eval_x): New function.
6732 * eval.c: Renamed debug option "deval" to "debug".
6734 (scm_eval_x): `eval!' is no longer accessible from the scheme
6735 level. Motivation: We can't allow operations which introduce
6736 glocs into the scheme level. Guile's type system can't handle
6737 these as data. Use `eval' or `read-and-eval!' as replacement.
6739 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6740 SCM_CONSP since this is a macro!; Set vframe.prev to
6741 scm_last_debug_frame instead of 0. In this way we can look
6742 "above" the virtual start stack frame if we wish.
6743 (scm_debug_hang): New function: Useful for debugging Guile in
6744 certain tricky situations. Will probably be removed later...
6746 * debug.h: Changed semantics of debug option "backtrace". This
6747 option now only indicates whether we want automatic backtrace at
6750 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6752 * ports.c: #include "filesys.h"
6753 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6755 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6756 Motivation: This is system specific code which is related to file
6757 I/O. It also may use select. Added code by Gary Houston to
6758 detect presence of character in stdio buffers.
6760 * libguile.h: #include "libguile/libpath.h"
6762 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6763 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6764 SCM_SITE_DIR; Install libpath.h among the other include files.
6766 * load.c, load.h (scm_sys_package_data_dir): New function.
6768 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6770 * stacks.h: Bugfix: Don't use tail-array length field as stack
6771 length field! This screwed GC.
6773 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6775 * _scm.h: Added #ifndef around definition of macros min and max.
6777 * __scm.h: Added hooks for threads to plugin to in ints protection
6778 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6779 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6780 the main code in these macros duplicated and spread over multiple
6781 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6782 SCM_THREAD_SWITCHING_CODE.
6784 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6786 * snarf.h: New file.
6787 * guile-snarf.sh: New file.
6788 * Makefile.in (inner_h_files): Added snarf.h
6789 (ancillary, install, uninstall, distclean): Added actions for
6791 (.c.x): Use guile-snarf.
6792 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6793 (gen_c_files): Note that these depend on guile-snarf.
6794 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6795 now in "snarf.h". Added #include "snarf.h" to get them.
6796 * libguile.h: Added #include "snarf.h".
6797 (Patches applied and tweaked by Jim Blandy.)
6799 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6801 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6802 standards suggest against providing prototypes for system
6803 functions. Thanks to Greg Troxel.
6805 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6807 * strports.c (scm_eval_0str): New function.
6808 #include "read.h", to get prototype for scm_read.
6809 * Makefile.in (strports.o): Update dependencies.
6810 * strports.h: New prototype.
6812 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6813 scheme name from "int?" to "integer?". It seems to do the job.
6814 * numbers.h: Rename prototype too.
6815 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6818 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6819 scm_num_eq_p): Rename these according to R4RS conventions: call
6820 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6821 to making libguile R4RS compliant without ice-9...
6823 * load.c (scm_sys_search_load_path): Search for files under all
6824 extensions listed in the %load-extensions variable. If FILENAME
6825 is absolute, return it unchanged, without searching the load path.
6826 (scm_loc_load_extensions): New variable, pointing to
6827 %load-extensions' value cell.
6828 (scm_init_load): Initialize it, and the value it points to.
6829 (scm_primitive_load_path): Improve error reporting.
6831 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6832 of new Scheme variable %load-hook.
6833 (scm_primitive_load): Apply %load-hook to filename.
6835 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6837 * configure.in: add tests for figuring out whether buffered data
6838 is available in a FILE structure, which is needed by char-ready.
6840 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6843 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6844 exceptions using misc_error instead of syserror. It seems a bit
6845 odd to throw an exception if a string can't be found in the
6846 environment, but it's consistent with open-file, stat etc.
6847 (simpos.h): remove sys_ from getenv.
6849 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6850 occurs, throw an error instead of returning errno. Return value
6852 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6854 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6856 * filesys.c (scm_stat2scm): derive file type and permissions from
6857 the stat mode and append them to the returned vector.
6858 There isn't much overhead in doing this and it avoids the need to
6859 work with S_IRUSR et al. in Scheme.
6860 Define symbols scm_sym_regular etc.
6861 (scm_init_filesys): don't intern S_IRUSR etc.
6863 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6864 and s_primitive_load_path.
6866 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6868 * error.h: don't declare error symbols. prototype for scm_misc_error.
6870 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6873 * error.c: use SCM_SYMBOL to set up error keys.
6874 scm_misc_error: new procedure.
6876 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6878 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6879 between `#!' and `!#' is ignored.
6880 (skip_scsh_block_comment): New function.
6882 * feature.c (scm_set_program_arguments): New argument, FIRST.
6883 * feature.h: Update prototype.
6884 * init.c (scm_boot_guile_1): Pass new argument to
6885 scm_set_program_arguments.
6887 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6889 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6890 (scm_boot_guile): Call scm_set_program_arguments here, later than
6891 the old initialization.
6893 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6894 initialization procedure.
6895 - Delete in, out, err arguments; there are other perfectly good
6896 ways to override these when desired.
6897 - Delete result argument; this function shouldn't ever return.
6898 - Rename init_func argument to main_func, for less confusion.
6899 - Delete boot_cmd argument; main_func is more general.
6900 -Add 'closure' argument, to help people pass data to main_func
6901 without resorting to global variables.
6902 - Abort if reentered; don't bother returning an error code.
6903 - Call scm_init_standard_ports to set up the default/current
6904 standard ports; no need to pass them to scm_start_stack.
6905 - Remove code to evaluate the boot_cmd, and start the repl; let
6906 the user do something like that in main_func if they want.
6907 - Remove code to package up a return value; main_func can do any
6909 - Call exit (0), instead of returning.
6910 (scm_start_stack): Don't initialize the I/O ports here; that's
6911 weird. Delete in, out, err arguments. Move guts to
6912 scm_init_standard_ports, scm_stdio_to_port.
6913 (scm_init_standard_ports): New function, to set up current and
6914 default standard ports.
6915 (scm_start_stack, scm_restart_stack): Make these static.
6916 * init.h (scm_boot_guile): Adjust declaration.
6917 (scm_start_stack, scm_restart_stack): Remove externally
6918 visible declarations for these.
6919 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6921 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6922 written out several times in scm_start_stack.
6923 * fports.h: New declaration for the above.
6925 * feature.c (scm_set_program_arguments): New function.
6926 * feature.h: New declaration for the above.
6928 * ports.c: Formatting tweak.
6930 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6932 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6933 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6934 for obtaining the address of a car or cdr field. Motivation:
6935 &SCM_CXR make assumptions about the internal structure of the
6938 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6939 Motivation: see SCM_CXRLOC.
6941 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6942 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6943 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6944 Motivation: Safer use. Some other macros are defined in terms of
6945 these operations. If these are defined using the SCM_SETCXR
6946 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6947 to inefficiency and an <e1> with side-effects could potentially
6948 break. Also, these particular operations are heavily utilized in
6949 the garbage collector. In unoptimized code there will be a
6952 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6953 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6954 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6955 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6956 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6957 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6958 vports.c: Cleaned up use of pairs: Don't make any special
6959 assumptions about the internal structure of selectors and
6960 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6961 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6962 (Among other things, this change makes it easier to build Guile
6963 with certain compilers which have problems with casted lvalues.)
6965 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6967 * stacks.c: Improve selection of relevant stack frames when making
6968 a stack object. Introduce one level of indirection in the stack
6969 object to make it possible to "narrow" to a certain region of the
6970 stack. This facilitates making use of more clever algorithms (not
6971 implemented) for selecting relevant frames and gives a cleaner
6972 design since selection of frames can be done independently of
6973 extraction of frames from the real stack.
6974 (scm_stack_id): Also take #t as argument which means look at
6977 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6978 Turn n_tail into an integer directly representing current number
6979 of frames in stack. Add field tail.
6981 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6983 * debug.c (scm_make_memoized): Made it available at scheme level.
6984 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6985 SCM_NIMP before applying heavier predicates in argument checking.
6986 (scm_local_eval): Also take memoized object as argument.
6988 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6989 aren't created with zero length, but should such a strange
6990 creature suddenly turn up...
6992 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
6994 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
6995 `del', for the sake of C++ compilers. (Patch applied by JimB.)
6997 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
6999 * variable.c (scm_make_variable): Make the name hint optional, as
7001 (anonymous_variable_sym): Renamed from variable_sym. All uses
7004 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7005 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7006 of scm_primitive_load_path was also changed to
7007 "primitive-load-path", from "%try-load-path". Callers changed.
7008 We'd like to respect the convention that a function named
7009 "try-mumble" should behave just like the function called "mumble",
7010 but return #f instead of signalling some error.
7011 * load.h: Rename prototypes.
7013 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7015 * print.c (make_print_state, grow_print_state), print.h: Modified
7016 the print state representation: Don't use a tail array for
7017 recording of circular references. Resizing of the print state
7018 structure invalidates the print state pointer. To avoid passing
7019 around an indirect print state reference to all printing
7020 functions, we instead let the print state reference a resizable
7023 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7025 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7026 Don't crash when passed an improper list terminated by a
7027 non-immediate value.
7029 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7031 Allocate data for structures on an eight-byte boundary, as
7032 required by the tagging system.
7033 * struct.c (alloc_struct): New function.
7034 (scm_make_struct, scm_make_vtable_vtable): Call it.
7035 * struct.h (scm_struct_n_extra_words): Bump to 3.
7036 (scm_struct_i_ptr): New "field".
7037 * gc.c (scm_gc_sweep): When we need to free the data, use the
7038 information stored by alloc_struct to find the beginning of the
7039 block allocated to the structure, so we can free it.
7041 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7043 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7046 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7047 (scm_debug_info): New member: id.
7049 * stacks.c: Stacks are now represented as structs; Stacks have an
7050 id given to them by `start-stack'.
7051 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7053 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7054 Changed stack representation.
7056 * debug.c (scm_procedure_name): Try procedure property `name' for
7057 compiled closures aswell.
7059 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7061 * eval.c: scm_i_name moved to gsubr.c
7062 (scm_m_define): Record names of all kinds of procedure
7063 objects. (Earlier, only closures were recorded.)
7065 * procprop.h: Added declaration of scm_i_name.
7067 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7068 (scm_make_gsubr): Record names of compiled closures.
7070 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7072 * debug.c, debug.h: Removed obsolete code.
7074 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7075 stacks.c: Renamed regs --> scm_contregs.
7077 * print.c (scm_free_print_state): Cleanup print state before
7078 returning it to pool. It is better to do it here than in
7079 scm_prin1 since scm_prin1 is called often.
7081 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7082 s_set_source_property_x): Check that first argument is a pair or a
7085 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7086 scm_i_line, scm_i_column and scm_i_breakpoint global.
7088 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7089 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7092 * debug.h: Added debug object smob declaration and macro
7095 * configure.in: Build with backtrace.o and stacks.o if debug
7098 * Makefile.in: Added entries for new files: backtrace.c,
7099 backtrace.h, stacks.c and stacks.h.
7101 * symbols.c (scm_sym2ovcell): Fixed documentation.
7103 * _scm.h (min, max): Added.
7105 * async.c: Moved `min' macro to _scm.h.
7107 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7108 SCM_BACKTRACE_INDENT.
7110 * eval.c: Added new debug options `maxdepth' and `indent'.
7112 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7114 * print.h: Added selector SCM_PRINT_STATE.
7116 * print.c: New functions: scm_make_print_state,
7117 scm_free_print_state.
7119 * print.h: Added declarations for scm_make_print_state,
7120 scm_free_print_state.
7122 * debug.c (scm_m_start_stack): New acro.
7124 * debug.h: Small cleanup.
7126 * init.c (scm_boot_guile_1): Moved scm_init_debug below

7151 declare functions with prototypes. (Patch thanks to Marius
7154 More prototype-related changes from Marius Vollmer:
7155 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7156 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7157 * ports.h (ptobfuns): Added prototypes. This means some casting in
7159 * fports.c: Added casts for initializations, since the functions
7160 are defined to take FILE * as their stream argument, not SCM.
7161 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7162 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7163 to `char *str_data' to conform to prototype.
7165 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7167 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7169 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7171 * stime.c, stime.h: use SCM_P method.
7173 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7175 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7176 be given at least two arguments. Insist that lst's last element
7177 be a list, but don't make any requirements of its predecessors.
7179 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7181 * eval.c (scm_nconc2last): Revert last change; there seems to be
7182 other stuff going on here.
7184 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7186 * eval.c (scm_nconc2last): Make sure that each element of lst
7187 (which is a list of argument lists, except for the tail) is a
7188 proper list, i.e., finite and terminated by '().
7190 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7192 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7195 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7196 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7199 * vectors.c (scm_make_vector): Fill vectors with the undefined
7200 value, to help make Guile Scheme code more portable to other
7203 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7204 * symbols.h, tags.h: Doc fixes.
7206 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7208 * async.c (scm_take_signal): Doc fixes.
7210 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7212 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7213 want to subtract it from the modulus; we just want to leave it
7216 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7218 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7221 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7223 * throw.c (scm_catch_apply): Finished implementation of
7226 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7228 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7230 (scm_init_filesys): set "i/o-extensions" feature.
7233 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7235 * Makefile.in (root.o): Correct dependencies.
7237 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7239 * Makefile.in: Added dependency entry for root.o.
7241 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7242 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7244 * init.c (scm_start_stack): Set initial root continuation number
7247 * procs.c: New function: scm_thunk_p.
7249 * procs.h: Added declarations of scm_thunk_p.
7251 * root.c: Renamed `call-with-new-root' -->
7252 `call-with-dynamic-root'.
7253 (cwdr): Removed allocation of new root state. This should be done
7254 separately by use of scm_make_root.
7255 (scm_apply_with_dynamic_root): New function: Does what it
7256 sounds like. Needed when spawning threads.
7258 * root.h: Added member last_debug_frame to root state.
7259 Added #include "libguile/debug.h"
7261 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7262 arguments. The motivation is that code in root.c needs catch
7263 functionality, and we want to avoid code duplication.
7264 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7265 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7266 handlers that run without popping the stack into the dynwind
7269 * throw.h: Added prototypes for scm_catch_apply and
7272 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7274 * root.h (scm_root, scm_set_root): Decouple thread support details
7275 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7276 SCM_SET_THREAD_LOCAL_DATA.
7278 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7279 and tortoise scanning loop.
7281 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7283 * Makefile.in: Rebuild dependencies.
7285 * libguile.h: #include "libguile/print.h" before "smob.h", since
7286 the latter uses the print_state structure.
7288 * throw.c (scm_ithrow): Use the correct variable when checking to
7289 see if a given element of scm_dynwinds is a valid catch.
7291 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7292 structure, abort; don't just silently ignore the garbage.
7294 * _scm.h: #include "print.h" here, since it seems to be used just
7296 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7297 strports.c, unif.h: Don't #include "print.h".
7299 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7301 * feature.h (scm_loc_features): Removed external declaration.
7302 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7304 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7306 * feature.c (scm_init_feature): Added threads feature (needs to be
7307 initialized here, since features doesn't exist when
7308 scm_init_threads is called).
7310 * libguile.h: Added #include "libguile/../threads/threads.h".
7311 (This is a kludge to get thread support working. This should be
7314 * configure.in, acconfig.h: Added flags for thread support.
7316 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7319 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7320 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7323 * _scm.h: Added conditional #include "threads.h"
7325 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7326 SCM_THREADS_SWITCHING_CODE.
7328 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7329 allocate the basic dynamic root object.
7330 (scm_boot_guile): Added call to scm_init_root.
7332 * root.c, root.h: Added root smob.
7333 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7334 functions: Implements dynamic roots mostly according to spec in
7335 SCM manual. Main difference is that the second argument is a
7336 throw handler rather than an error "thunk".
7338 * root.h: Added declaration of scm_init_root.
7340 * root.c: Added #include "genio.h", #include "smob.h", #include
7341 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7343 (scm_init_root): Added #include "root.x".
7345 * throw.c: Added #include "stackchk.h"
7346 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7347 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7348 can be used in scm_call_with_new_root; Added reenabling of stack
7349 checking when catching a throw.
7351 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7353 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7355 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7356 element is not found, as per R4RS.
7358 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7360 * list.c: Doc fixes throughout.
7362 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7364 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7365 declare the char * to be const. Avoids a warning in rgx.c.
7367 * ports.h: spelling fix.
7369 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7372 * load.c (scm_sys_try_load_path): throw an error if file not found
7373 (like it says it in NEWS).
7375 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7377 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7378 PROPS slot to '(), not #f; it's an empty alist.
7380 * throw.h, throw.c: Use SCM_P instead of #if hair.
7382 Remove special support for uncaught throws; see throw.c for
7384 * throw.c (uncaught_throw): New function.
7385 (scm_ithrow): Call uncaught_throw if we don't find a throw
7386 target; don't mess with scm_bad_throw_vcell.
7387 (scm_bad_throw_vcell): Variable deleted.
7388 (scm_init_throw): Don't initialize it.
7390 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7393 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7395 * numbers.c (scm_istr2int): If the number is short (as most
7396 numbers are), just call scm_small_istr2int to deal with it.
7397 (scm_small_istr2int): New function, created by un-#ifdefing the
7398 non-bignum version of scm_istr2int and renaming it.
7400 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7402 * load.c (scm_sys_try_load): don't check whether value returned
7403 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7404 Change the Scheme name from %try-load to primitive-load.
7406 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7407 Can avoid passing a message, allowing it to be derived in the
7408 error handler (e.g., if we want to throw to the key both from
7411 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7413 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7414 references now have a new appearance which is more compact and
7415 also gives a clue about what the target of the reference is.
7416 By setting parameters in the print state, more fancy printing can
7417 be achieved. This is used by the (not yet commited) backtrace
7420 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7422 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7425 * print.c: Added #include "struct.h". Removed function
7428 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7429 scm_iprin1. Removed prototype for scm_prlist.
7431 * arbiters.c (prinarb),
7432 async.c (print_async),
7433 debug.c (prindebugobj, prinmemoized),
7434 eval.c (prinprom, prinmacro),
7435 filesys.c (scm_fd_print, scm_dir_print),
7437 mallocs.c (prinmalloc),
7438 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7439 smob.h (scm_smobfuns),
7440 srcprop.c (prinsrcprops),
7442 unif.c, unif.h (scm_raprin1, rapr1),
7443 variable.c (prin_var): Changed argument `int writing' to
7444 `scm_print_state *pstate'.
7446 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7447 that it will be called before scm_init_print.
7449 * print.c (scm_prin1): Print states are now allocated when calling
7450 scm_prin1 and then passed around to all printing functions as an
7451 argument. A cache `print_state_pool' enables reuse of print
7453 (scm_make_print_state): New function.
7454 (scm_iprin1): Adaption to print states.
7455 (scm_iprlist): An initial "hare and tortoise" scan brings down
7456 time complexity to O (depth * N). (Better time complexity will be
7457 achieved when the printing code is completely rewritten.)
7459 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7461 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7462 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7463 it gets done whether or not the cache variable has a value.
7465 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7467 Distinguish #f and ().
7468 * __scm.h: #undef SICP.
7469 * pairs.h (SCM_EOL): Delete this definition, equating it with
7471 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7472 the value it used to have. Doc fixes, too.
7474 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7476 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7477 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7478 Lord's implementation of structs, allowing for tail arrays as
7479 described in the manual. Also fixed some bugs. (Both the interface
7480 and the implementation should be improved.)
7482 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7484 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7485 People who whish to see the source can do `(print-enable 'source)'.
7486 Removed #ifdef DEBUG_EXTENSIONS.
7488 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7490 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7491 integer (assuming for now accepting an integer is a good thing).
7493 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7494 %S will be used instead for write'ing arguments.
7496 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7497 asserts. fix a few other asserts.
7498 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7499 scm_uniform_vector_ref, scm_array_set_x,
7500 scm_dimensions_to_unform_array): change args in
7501 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7502 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7503 scm_substring_fill_x): likewise.
7504 gsubr.c (scm_gsubr_apply): likewise.
7505 eval.c (SCM_APPLY): likewise.
7507 * eval.c (4 places): replace scm_everr with lgh_error or
7510 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7511 scm_memory_error): new procedures.
7512 scm_everr: deleted. can use scm_wta, dropping first two args.
7513 scm_error: convert NULL subr to SCM_BOOL_F.
7515 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7518 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7521 * error.c, error.h: new error keys: scm_arg_type_key,
7522 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7524 scm_wta: reimplement using lgh_error instead of scm_everr.
7526 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7528 * gdbint.c: scm_lread now has one more argument.
7530 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7531 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7532 loading source from non-file ports, which, e. g., happens when
7533 using the Emacs interface).
7535 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7538 * read.c: Added code for recording of positions of source code
7539 expressions; New functions: recsexpr, scm_lreadrecparen;
7540 _scm_make_srcprops --> scm_make_srcprops
7541 (scm_flush_ws): Removed updating of positions counters. This work
7542 is already done by scm_gen_getc
7544 * read.h: Added prototype for scm_lreadrecparen
7546 * print.c: Added #include "alist.h"
7548 * eval.c: Added #include "hash.h"
7550 * eq.c: Added #include "ramap.h"
7552 * options.c: Documentation fixes.
7554 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7555 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7556 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7557 --> scm_make_srcprops
7559 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7560 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7561 function calls in the definition of the whash access macros.
7563 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7565 * init.c (scm_boot_guile): Add level of indirection to
7566 scm_boot_guile_1() to ensure that stack base pointer is properly
7567 initialized. There was no guarantee that variable i was the
7568 highest/lowest variable on stack (i.e. the call frame of
7569 scm_boot_guile was not completely protected from gc).
7571 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7573 * ports.h (scm_port_table): put back file_name, it will be used to
7574 support debugging. Undo related changes in fports.c, ioext.c,
7577 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7579 * ports.h (scm_port_table): remove file_name member for now, it seems
7581 * fports.c (scm_open_file): don't set file_name in PTAB.
7582 (prinfport): don't use file_name in PTAB.
7583 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7584 * ports.c (scm_add_to_port_table): don't intialize file_name.
7585 (scm_port_file_name): remove for now.
7586 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7588 * fports.h (scm_mkfile): prototype deleted.
7589 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7591 * debug.c, unif.c: use scm_out_of_range instead of
7592 wta for range errors (ASSERT still needs work).
7594 * error.c, error.h (scm_out_of_range): new procedure.
7596 * error.c, error.h (scm_out_of_range_key): new key.
7598 * posix.c (scm_sync): #else was missing.
7600 * error.c, error.h: append _key to names scm_num_overflow and
7603 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7604 of consing an empty list.
7605 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7606 of macros, saves code and string space.
7607 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7608 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7609 lower case. Rename scm_syserror_m to scm_syserror_msg.
7610 error.h: prototypes for new procedures.
7612 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7614 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7616 * error.c, error.h: setup scm_num_overflow key.
7618 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7619 Remove definition of SCM_OVSCM_FLOW.
7621 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7623 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7624 explicit message and args.
7626 * error.c, error.h, __scm.h: change system_error_sym to
7629 * error.c (system_error_sym): remove leading %% from the Scheme name
7632 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7634 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7636 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7637 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7638 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7639 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7640 renamed. (These were introduced by unsupervised name
7643 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7645 * print.c: Added code for detection of circular references during
7646 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7647 a hook for printing of closures (accessible via print options).
7648 This leads to a split of calls to scm_iprin1 into two classes:
7649 elementary print operations (e. g. the code which prints a smob)
7650 still use scm_iprin1 while top level calls (like scm_display) use
7651 scm_prin1. scm_prin1 begins by clearing the data structure used
7652 to record reference information.
7654 * print.h: Added declarations of scm_prin1 and scm_prlist.
7656 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7658 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7660 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7662 * error.c (err_head): scm_iprin1 --> scm_prin1
7664 * debug.c: Adjusted header comment.
7668 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7670 * strerror.c: Doc fix.
7672 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7674 * gdbint.c (gdb_read): Now possible to run during GC.
7675 (unmark_port, remark_port): New functions.
7677 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7679 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7680 of allocating a new string object. Also, increase size by
7681 the factor 2 instead of 1.5.
7683 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7685 * __scm.h (SCM_P): Corrected to run under traditional C.
7687 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7690 * async.c: Calls to scm_sysintern corrected.
7692 * async.h (scm_async_clock): Redundant declaration removed.
7694 * continuations.c (scm_dynthrow): Redundant declaration removed.
7696 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7697 Definition typos corrected.
7699 * debug.h: Missing declarations of functions in debug.c added
7702 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7703 Missing declarations to functions in eval.c added.
7705 * filesys.c: Possibly uninitialized variable rv.
7707 * gc.h (scm_object_addr, scm_unhash_name): Missing
7708 declarations of functions defined in gc.c added.
7710 * genio.c: Possible typos str_data -> wstr_data. ???
7712 * genio.c: Possibly unintended shadowing of local variable
7713 `int c' (gotos out of scope of inner `c'). ???
7715 * init.c: Uninitialized `SCM last' may be used.
7717 * ioext.h: (scm_sys_isatty_p): Typo.
7719 * list.h (scm_list_head): Missing prototype for function in
7722 * numbers.c (scm_two_doubles): Changed from extern to static
7723 (is used only within numbers.c).
7725 * numbers.h: Repeated declarations removed.
7727 * ports.h (scm_close_all_ports_except): Declaration for the
7728 function defined in ports.c added.
7730 * posix.h: Missing declarations added.
7732 * procs.h (scm_make_subr_opt): Missing declaration added.
7734 * socket.h (scm_sys_gethost): Missing declaration added.
7736 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7738 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7739 Missing declarations added.
7741 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7743 * struct.c: Uninitialized variable `SCM answer' may be used.
7745 * unif.c (l2ra): Declaration prototype.
7747 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7748 defined in ramap.c).
7750 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7751 Redundant declarations removed (they are in ramap.h).
7753 * variable.h (scm_make_udvariable,
7754 scm_make_undefined_variable): Declaration corrected to
7755 correspond variable.c.
7757 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7758 Missing declarations added.
7760 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7762 * Makefile.in (distclean): Don't forget to delete fd.h.
7764 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7766 * fd.h.in, tags.h: Trivial cleanups.
7768 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7769 marksweep.h just declared functions from gc.c.
7770 * gc.h, libguile.h: Don't #include "marksweep.h".
7771 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7772 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7773 dependencies updated.
7775 * libguile.h: Don't #include "files.h"; it's been deleted.
7777 * files.c (scm_sys_delete_file): Moved to filesys.c.
7778 File is now empty; deleted.
7780 * filesys.c: scm_sys_delete_file is now here. Remove
7781 #if's; they seem to rely on remnants of an old portability
7782 regimen. If the problems come up again, solve them properly,
7783 using autoconf. Specifically: Don't test M_SYSV, and #define
7784 remove to be unlink if it's #defined; don't use remove just
7785 because HAVE_STDC_HEADERS is #defined.
7786 * filesys.h: Add declarations for scm_sys_delete_file.
7787 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7788 files.o, files.h, files.c, and files.x.
7789 * init.c: Don't #include "files.h", and don't call scm_init_files.
7791 Use SCM_P instead of PROTO; the latter intrudes on the user's
7793 * params.h: Deleted; definition of SCM_P moved to...
7794 * __scm.h: ... here, where it replaces PROTO macro.
7795 * libguile.h, smob.h: Don't #include "params.h".
7796 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7797 smob.h: Fix prototypes accordingly.
7798 * Makefile.in: Update dependencies.
7799 (inner_h_files): Remove params.h.
7801 * gc.c: #include "gc.h"; every module should include its header,
7802 to let the compiler cross-check the declarations against the
7805 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7806 simpos.h: #include "libguile/__scm.h".
7808 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7810 * init.c: Don't forget to #include smob.h and init.h.
7811 * Makefile.in: Dependencies updated.
7813 * smob.h: Use PROTO instead of #if __STDC__.
7815 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7817 * __scm.h: Doc fixes.
7819 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7820 <angles>; this allows `make depends' to work properly.
7822 * libguile.h: #include smob.h and pairs.h before the others; they
7823 define typedefs used by other headers.
7825 C files should #include only the header files they need, not
7826 libguile.h (which #includes all the header files); the pointless
7827 recompilation was wasting my time.
7828 * Makefile.in (all .o dependency lists): Regenerated.
7829 * libguile.h: Don't try to get a definition for size_t here...
7830 * __scm.h: Do it here.
7831 * _scm.h: Since this is the internal libguile header, put things
7832 here that all (or a majority) of the libguile files will want.
7833 Don't #include <libguile.h> here; that generates dependencies on
7834 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7835 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7836 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and
7838 * alist.c: Get "eq.h", "list.h", "alist.h".
7839 * append.c: Get "append.h", "list.h".
7840 * arbiters.c: Get "arbiters.h", "smob.h".
7841 * async.c: Get "async.h", "smob.h", "throw.h", "eval.h".
7842 * boolean.c: Get "boolean.h".
7843 * chars.c: Get "chars.h".

7933 * weaks.c: Get "weaks.h".
7935 * stackchk.h: #include "libguile/debug.h",
7937 * print.h, read.h: #include "options.h", since everyone who uses
7938 either of these files will need that.
7940 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7941 anyone who uses this file will need them to define the smob
7942 printing functions. Also, get markers.h, since people will need
7943 to #define the mark functions.
7945 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7946 * ports.h: ... to here.
7948 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7949 don't rely on archaic C default type rules.
7951 * fports.h: #include "libguile/ports.h", since you need that in
7952 order to parse this.
7954 * genio.h: #include "libguile/print.h", because you need that to
7955 parse this; don't bother #including "ports.h", since print.h gets
7958 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7960 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7961 this; it's now a reference to an element of *scm_root.
7963 * debug.h: Don't #include "options.h"; the compiler won't be able
7964 to find that once the headers are installed; instead, #include
7965 "libguile/options.h".
7966 * gc.h: Same, with marksweep.h.
7967 * mbstrings.h: Same, with symbols.h.
7968 * scmhob.h: Same, with _scm.h.
7969 * smob.h: Same, with params.h.
7971 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7972 C files; there's no need for this, and it forces recompilations
7975 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7977 * error.c (scm_error): declare scm_error_callback.
7979 * error.h: prototype for scm_error_callback.
7981 * __scm.h: define lgh_error.
7982 (SCM_SYSERROR): redefine using lgh_error.
7984 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7986 * error.c (scm_error): new procedure.
7988 * error.h: prototype for scm_error.
7990 * Makefile.in (install): install scmconfig.h from the current
7991 directory, not $(srcdir).
7993 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7995 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7996 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7997 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
7998 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
7999 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,

8002 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8003 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8004 vports.h, weaks.h: #include "libguile/__scm.h", not
8005 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
8006 dependencies are within libguile properly.
8008 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8010 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8011 when scmconfig.h doesn't exist.
8013 * load.c (scm_sys_try_load): Correct spelling.
8015 * feature.c (scm_loc_features): Make this static.
8017 * Makefile.in (libpath.h): Omit trailing slash from path. We
8018 shouldn't require it of users, so why put it here?
8020 Move code to initialize and search %load-path from ice-9 to C
8021 code, so we can use the load-path to find the ice-9 boot code;
8022 this makes it easier to run Guile without installing it. See
8023 corresponding changes in guile/Makefile.in.
8024 * feature.c: Move stuff concerned with the load path to load.c.
8025 (scm_compiled_library_path): Deleted.
8026 Don't #include libpath.h here.
8027 * feature.h: Don't mention scm_compiled_library_path.
8028 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8029 <sys/stat.h>, and <unistd.h> (if present).
8030 (R_OK): #define if the system hasn't deigned to.
8031 (scm_loc_load_path): New variable.
8032 (scm_init_load_path, scm_sys_search_load_path,
8033 scm_sys_try_load_path): New functions.
8034 (scm_init_load): Initialize scm_loc_load_path to point to the
8035 value cell of the Scheme %load-path variable.
8036 * load.h: Add declarations for scm_sys_search_load_path,
8037 scm_sys_try_load_path.
8038 * init.c: Call scm_init_load_path.
8039 * Makefile.in (feature.o, load.o): Dependencies updated.
8041 * load.c, load.h: Rewrite using PROTO macro.
8043 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8045 * gc.c (scm_cellp): New function: C predicate to determine if an
8046 SCM value can be regarded as a pointer to a cell on the heap.
8048 * gc.h: Added declaration of scm_cellp.
8050 * gdb_interface.h: New file: The GDB interface header from the GDB
8053 * gdbint.c: New file: GDB interface.
8055 * gdbint.h: New file: GDB interface.
8057 * libguile.h: Added #include <libguile/gdbint.h>.
8059 * init.c (scm_boot_guile): Added scm_init_gdbint.
8061 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8062 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8063 found if object files and source are kept separate).
8065 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8067 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8069 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8071 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8072 TK_SRC_DIR; they're not relevant any more.
8074 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8075 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8077 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8079 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8080 search path, so we can find the <libguile/MUMBLE.h> headers.
8082 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8084 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8085 implicit in the .c.o rule.
8086 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8089 Put the library path in a header file, instead of passing it on
8090 the command line in every compilation.
8091 * Makefile.in (libpath.h): New target.
8092 (feature.o): Depend on libpath.h.
8093 (clean): Delete libpath.h.
8094 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8095 * feature.c: ... #include "libpath.h" here.
8096 * .cvsignore: Ignore libpath.h.
8098 Don't install the unwashed masses of Guile header files in the
8099 main #include path; put most of them in a subdirectory called
8100 'libguile'. This avoids naming conflicts between Guile header
8101 files and system header files (of which there were a few).
8102 * Makefile.in (pkgincludedir): Deleted.
8103 (innerincludedir): New variable; this and $(includedir) are enough.
8104 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8105 (installed_h_files): Divide this up. Now this variable lists
8106 those header files which should go into $(includedir) (i.e. appear
8107 directly in the #include path), and ...
8108 (inner_h_files): ... this new variable says which files appear in
8109 a subdirectory, and are referred to as <libguile/mumble.h>.
8110 (h_files): List them both.
8111 (install): Create innerincludedir, not pkgincludedir. Put
8112 the installed_h_files and inner_h_files in their proper places.
8113 (uninstall): Corresponding changes.
8114 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8115 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8116 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8117 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8118 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8119 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8120 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8121 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8122 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8123 vports.h, weaks.h: Find __scm.h in its new location.
8124 * __scm.h: Find scmconfig.h and tags.h in their new locations
8125 (they're both "inner" files).
8127 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8129 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8131 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8133 * posix.c: Doc fixes.
8135 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8137 * socket.c: Don't include a prototype for inet_aton; just use a
8138 K&R style declaration, to avoid warnings but minimize the chance
8139 of conflicts with the system.
8141 On NextStep, <utime.h> doesn't define struct utime, unless we
8142 #define _POSIX_SOURCE before #including it.
8143 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8144 * acconfig.h: New comment text for above CPP symbol.
8145 * configure.in: Call it.
8146 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8148 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8150 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8151 testing for __EMX__.
8153 * posix.c: #include <libc.h>, if it exists.
8155 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8156 don't even know if the latter exists.
8158 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8159 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8160 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8162 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8164 (scm_init_posix): Use them when initializing the Scheme constants
8167 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8169 * Makefile.in (libdir, includedir, bindir): Use the
8170 autoconf-supplied values, instead of deriving them ourselves.
8171 (pkgincludedir, datadir, pkgdatadir): New variables.
8172 (install, uninstall): Put the header files in a special
8173 subdirectory, not in the main search path.
8175 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8176 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8178 * Makefile.in (IMPLPATH): Deleted; never used.
8180 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8181 on the Tcl/Tk source any more.
8182 (INCLUDE_CFLAGS): Remove references to the above.
8184 * Makefile.in (version.o): Corrected dependencies.
8186 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8188 * libguile.h: #include "version.h"
8190 * init.c (scm_boot_guile): Call scm_init_version.
8191 * gscm.c (gscm_run_scm): Call scm_init_version.
8193 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8194 GUILE_VERSION): AC_DEFINE these.
8195 (acconfig.h): #undef the above symbols.
8197 * Makefile.in (libobjs): Add version.o.
8198 (installed_h_files): Add version.h.
8199 (c_files): Add version.c.
8200 (gen_c_files): Add version.x.
8201 (version.o): New rule.
8202 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8203 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

8212 weaks.o): Add version.h to dependency lists.
8213 (markers.o): Remove duplicate rule.
8215 * version.h: New file.
8217 * version.c: New file.
8219 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8221 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8222 array; use it appropriately. Since GCC is quite happy to
8223 subscript functions, it never warned us about this; we should use
8224 -Wpointer-arith in the future. I guess we never tested
8227 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8229 * socket.c: Doc and copyright fixes.
8231 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8233 * debug.c: Fixed and improved gdb support.
8235 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8237 * socket.c: Added declaration of inet_aton to avoid compiler
8238 warning. (Hope this solution is correct.)
8240 * stime.c: Added declaration of ftime. (This is missing in
8243 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8245 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8247 * Makefile.in (c_files): add strerror.c.
8249 * strerror.c: new file from Emacs' sysdep.c.
8250 maybe configure should also check for sys_errlist.
8252 * configure.in (AC_REPLACE_FUNCS): add strerror.
8254 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8256 * debug.c (scm_init_debug): Added initialization for
8257 scm_evaluator_traps.
8259 * debug.h, debug.c: Various name changes.
8260 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8261 "debug-options-interface". See commentary in options.c.
8263 * options.h, options.c: Options now have documentation strings.
8264 Also added a long explanatory commentary.
8266 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8269 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8270 last_debug_info_frame is now updated in all cases.
8272 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8275 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8277 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8278 Added option STACK_CHECKING.
8280 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8282 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8284 * __scm.h: Removed symbols for debugging support.
8286 * acconfig.h: Added symbols for debugging support.
8288 * configure.in: Added user option for debugging support.
8289 --enable-debug will include the debugging code into libguile.a.
8291 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8292 scm_relocate_chunk_to_heap.
8294 * debug.c: New file: low-level debugging support. It also
8295 includes support for debugging with gdb. (The extensions to gdb
8296 are written by Per Bothner at Cygnus.)
8298 * debug.h: New file: low-level debugging support.
8300 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8301 argument pairs. Extensive modifications to the debugging
8302 evaluator. Added "SECTION:" commentaries to clarify what happens
8303 when, during double compilation. Renamed EVALIMP --> EVALIM.
8304 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8305 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8306 the beginning of the file. New procedure: scm_unmemocopy.
8307 Added some global state variables needed by the debugging
8308 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8309 check_entry, check_apply, check_exit, debug_options and
8310 evaluator_traps. New acro: undefine.
8312 * eval.h: Renamed EVAL --> XEVAL.
8314 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8315 --> scm_make_weak_key_hash_table.
8317 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8318 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8320 * libguile.h: Conditionally include debug.h
8322 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8323 scm_object_properties shouldn't return handle. `handle' now gets
8324 initialized in scm_set_object_properties_x. scm_object_properties
8325 doesn't any longer create an entry in scm_object_whash.
8327 * options.c: New file: handling of run time options.
8329 * options.h: New file: handling of run time options.
8331 * posix.c (scm_getpgrp): Cast pointer to getpgrp.

8352 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8354 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8356 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8358 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8359 and should be called by the final client.
8361 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8363 * gc.h: Use the PROTO macro when declaring functions.
8364 * gc.c: Use the PROTO macro when declaring static functions.
8365 Remove the CPP hair around function definitions.
8367 * gc.c (scm_init_storage): Initialize scm_asyncs.
8369 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8370 preprocessor symbol; "__scm.h" is where it might get #defined.
8371 * __scm.h: Similar: #include <scmconfig.h> before testing
8374 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8376 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8378 * init.c (scm_boot_guile): Add init_func argument; call
8379 (*init_func) instead of calling scm_appinit; it's ucky to
8380 hard-code names for the user's procedures.
8381 * init.h (scm_boot_guile): Adjust declaration.
8383 * __scm.h (PROTO): New macro, for declaring functions with
8386 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8387 eliminate all the __STDC__ conditionals.
8388 (scm_boot_guile): Add declaration.
8389 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8390 Remove __STDC__ conditionals around function definitions; the
8391 declarations in init.h will provide the same information, more
8394 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8395 complain about it in the error message; the error message is
8396 adequate without that note, and there's nothing the user can do
8399 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8401 * Makefile.in (ancillary): Drop def.sed.
8403 * posix.c (scm_init_posix): Use numeric values, rather than
8404 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8405 F_OK. The symbols aren't available on some systems, and I'm
8406 pretty sure their values are fixed by common widespread practice.
8407 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8409 More functions unavailable on some systems.
8410 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8411 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8413 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8414 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8415 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8416 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8417 stub that signals an error as the #else.
8419 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8421 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8423 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8425 * unif.c: include ramap.h.
8427 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8429 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8431 * ports.c: include sys/ioctl.h.
8433 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8435 * configure.in: check for sys/ioctl.h.
8437 * ports.c: include <malloc.h> not "malloc.h".
8439 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8441 * fports.c: remove ttyname and tmpnam declarations.
8443 * posix.c: fewer ttyname declarations.
8445 * fports.c: include <string.h> not "string.h".
8447 * init.c, ioext.c: include string.h and unistd.h.
8449 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8451 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8452 genio.c, simpos.c, vports.c: include string.h.
8454 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8456 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8458 (scm_addr_buffer_size): change type from scm_sizet to int.
8459 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8460 from scm_sizet to int.
8462 * error.c: include unistd.h.
8464 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8467 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8469 * __scm.hd, def.sed: deleted.
8471 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8473 Changes for NeXT, suggested by Robert Brown.
8474 * configure.in: Call AC_TYPE_MODE_T.
8475 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8476 NeXT. Put header file list in alphabetical order.
8477 * configure, scmconfig.h.in: Regenerated.
8478 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8480 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8483 * acconfig.h: New file, providing documentation for the CPP
8484 symbols defined in configure.in
8485 * acconfig-1.5.h: Removed; superceded by the above.
8487 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8489 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8491 * fports.c (scm_open_file): don't return #f, throw error.
8493 * ioext.c (fileno): renamed from %fileno.
8494 (soft-fileno): deleted.
8496 * ports.c (scm_port_revealed): don't need to check for -1 from
8498 (scm_set_port_revealed_x): return unspecified, not #f.
8500 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8502 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8504 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8506 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8508 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8510 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8511 This is necessary on Ultrix, and doesn't hurt portability.
8513 * Makefile.in (dist-dir): New target, implementing a new dist system.
8514 (installed_h_files): Put in alphabetical order.
8515 Remove duplicate entries for markers.h and unif.h.
8516 (c_files): Remove duplicate entries for markers.c.
8517 (ancillary): Renamed from anillery; all uses changed. Remove
8518 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8519 Remove all the ../doc/* files; doc/Makefile.in handles that.
8521 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8523 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8524 every if must have an else, or else the whole command has a
8525 non-zero exit code whenever the if's condition is false.
8527 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8529 * posix.c: include string.h.
8531 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8533 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8536 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8537 Remove leading % from scheme names.
8538 Do not return error values, call SCM_SYSERROR or similar.
8540 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8542 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8544 * struct.c (scm_init_struct): new file.
8546 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8548 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8549 (scm_list_head): added list-head for rapidly chopping argument
8550 lists off of longer lists (and similar).

8555 handle for obj, not the handle itself.
8557 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8559 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8560 weak hash tables last of all marking to avoid an obscure gc bug.
8561 WARNING: circular lists stored in a weak hash table will hose us.
8563 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8565 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8566 new functions similar to scm_substring_move_left_x and
8567 scm_substring_move_right_x.
8569 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8571 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8574 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8576 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8578 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8580 * strports.c (scm_strprint_obj): convenience function. C for
8581 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8583 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8584 removed to a separate library
8586 * init.c (scm_boot_guile): copied from guile-tcl.c.
8587 Initialization specific to tcl interpreters removed.
8589 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8591 * ports.c (scm_ports_prehistory): size malloced here doesn't
8592 matter so long as it is non-0 (got rid of "* 4").
8594 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8596 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8597 since its definition was bogus).
8599 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8601 * mallocs.[ch]: back again (for rx at least).
8603 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8605 * ports.c: removed functions relating to the mapping between ports
8606 and descriptors. (That stuff is unix-specific and should be collected
8607 in a separate library).
8609 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8610 (Tom Mckay@avanticorp.com)
8612 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8614 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8615 handled correctly (SCM_FREEP was applied to them) -- test for
8616 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
8617 being overwritten with #f. (brown@grettir.bibliotech.com)
8619 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>

8649 NOTE: don't use a alist here.
8650 (scm_set_procedure_properties_x): fix type checking throughout this file.
8652 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
8654 * ports.c (scm_remove_from_port_table): adjust scm_mallocated

8660 * vports.c (scm_make_soft_port): allocate a port table entry
8661 (possibly triggering gc) before setting the tag of the corresponding
8664 * pairs.c (scm_delq_x): never throw an error.
8666 * vectors.c (scm_make_vector): made the default vector fill argument
8667 into '() (much more useful than the previous value, "#unspecified")
8669 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
8671 * ports.c (scm_add_to_port_table): Added fields
8672 to port table entries: file_name, line_num, col.
8673 Update these in open_file, gen_getc and gen_ungetc.
8674 Added procedures to access those fields.
8676 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
8678 * procs.c (scm_make_subr_opt): new entry point for making
8681 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
8683 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
8685 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
8687 * numbers.c (scm_exact_p): This function no longer
8688 implements "integer?".
8690 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
8692 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
8693 (scm_gc_stats): return an assoc of useful data. Replaces "room"
8694 and the stats reporting formerlly built into repl.
8696 * repl.[ch]: removed.
8697 GC statistics keeping moved to gc.c.
8698 Other statistics keeping can be done from Scheme.
8699 REPLS are now written in Scheme.

8706 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
8708 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
8710 * feature.c (scm_compiled_library_path): moved here from repl.c.
8711 This file is for stuff relating specifically to Scheme libraries
8714 * eval.c (scm_m_define): don't give warning about redefinition, don't
8717 NOTE: this should throw a resumable exception with parameters --
8718 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
8720 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.

8738 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
8741 * strports.c: don't reveal the port's string to the caller
8742 because it changes size.
8744 (stputc stwrite): check/change the strings length with interrupts
8747 * objprop.c (scm_set_object_property_x &c): use the generic
8748 hashing functions and be threadsafe.
8750 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
8751 (per suggestion jaffer@gnu.ai.mit.edu).
8753 * mbstrings.c (scm_multi_byte_string): guard against argument list
8756 * strings.c (scm_make_string): loop cleanup

8784 initialization to fix a race condition.
8786 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

8809 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
8810 set the multi_byte flag correctly in symbols. This is wrong.
8811 intern_obbary_soft and msymbolize should take an extra parameter.
8812 Also, weird multibyte symbols don't print correctly.
8813 The weird symbol syntax is also a bit bogus (emacs doesn't quite
