1 1999-09-05 James Blandy <jimb@mule.m17n.org>
3 * guile-snarf.c: New implementation of guile-snarf, meant to be
4 more robust than the shell script. I think it's complete, but I
5 haven't tested it at all, and I haven't changed the build process
6 to actually use it. We should compare its output against that of
7 the existing shell script, for all source files.
9 * guile-snarf.c (parse_args): Abort if we haven't handled some
12 1999-09-03 James Blandy <jimb@mule.m17n.org>
14 * load.c (scm_search_path): If the filename has any extension at
15 all, ignore the entire list of extensions. Also, don't check whether
16 the file is accessible. If the file exists, accessible or not, we
17 should return it. Inaccessible files should cause an error later.
18 (Thanks to Keisuke Nishida for the suggestions.)
20 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
22 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
23 atexit not available. (sunos4.1.4 needs it.)
25 1999-09-01 James Blandy <jimb@mule.m17n.org>
27 I take it all back --- bcopy does handle overlapping source and
28 destination areas correctly. At least on every system I could
29 find. But it is better to use AC_REPLACE_FUNCS than to introduce
31 * memmove.c: New file, implementing memmove in terms of bcopy.
32 * scmconfig.h.in: Regenerated.
34 Allocators should use the `void *' type for generic pointers.
35 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
36 argument and return types.
37 * gc.h: Corresponding changes to prototypes.
40 1999-08-31 James Blandy <jimb@mule.m17n.org>
42 * numbers.c (scm_init_numbers): Claim to support the `complex'
43 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
45 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
46 find (ice-9 boot-9) when Guile was compiled in a separate
47 directory from the source. (Thanks to Rodney Brown.)
48 * Makefile.in: Regenerated.
50 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
51 table lengths by the size of a single element when growing the
52 table. (Thanks to Bill Schottstaedt.)
54 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
56 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
57 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
58 since that cuts down the time for type dispatch by 50%.
60 1999-08-30 James Blandy <jimb@mule.m17n.org>
62 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
63 not a correct substitute for memmove, because it doesn't handle
64 overlapping source and destination areas on many platforms.
65 Overlaps are the primary reason to use memmove in the first place.
66 * ports.c (scm_ungetc): Same.
67 * strop.c (scm_substring_move_x): Same.
69 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
71 * gc.c (scm_init_storage): Skip registration of cleanup on systems
72 which lack atexit. (Is it important that cleanup is made
73 properly? Maybe we should replace all `exit' with `scm_exit' and
76 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
77 scm_struct_free_standard, scm_struct_free_entity): Declared to
78 return scm_sizet instead of size_t.
80 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
83 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
85 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
86 Account for the case when second argument is unbound.
88 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
89 (Thanks to Karoly Lorentey.)
91 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
92 isn't present. (Thanks to Suzuki Toshiya.)
94 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
97 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
100 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
101 Bernard Urban and Ian Grant.)
103 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
104 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
105 change in the representation of entities and operators.)
107 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
109 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
110 don't allocate zero bytes (thanks to Bill Schottstaedt).
112 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
114 * procs.c (scm_setter): Converted to use generic dispatch.
116 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
119 * load.c (scm_search_path): Don't try extensions which already are
120 present at the end of the filename.
121 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
123 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
125 Cleanup and simplification of generic method dispatch.
126 Also, the quadruple representation of entity and operator
127 procedures has been replaced with single.
129 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
131 * print.c (scm_isymnames): Removed #@hash-dispatch.
133 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
134 from eval.c; Support 0 arity methods.
135 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
136 (scm_apply_generic_env): Removed.
137 Replaced slots proc0-3 with procedure.
139 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
140 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
141 SCM_OPERATOR_PROCEDURE.
142 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
143 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
145 * struct.c, struct.h: Replace 4 procedure slots with one.
146 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
148 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
151 * eval.c (scm_sym_args): Removed.
152 (SCM_CEVAL): Simplified entity application.
153 Moved dispatch code to objects.c.
155 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
157 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
159 * sort.c (closureless): Use scm_eval_body.
161 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
162 with a symbol as last form was first called normally and then via
163 `map' or some other mechanism using primitive apply, an ILOC was
166 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
168 This change extends the representation of primitive procedures
169 with more data fields, e.g. a place for documentation and true
170 procedure properties.
172 * procs.c, procs.h (scm_subr_entry): New type: Stores data
173 associated with subrs.
174 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
175 SCM_SUBR_DOC): New macros.
176 (scm_subr_table): New variable.
177 (scm_mark_subr_table): New function.
179 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
181 * gc.c (scm_gc_mark): Don't mark subr names here.
182 (scm_igc): Call scm_mark_subr_table.
185 This change implements a scheme for letting a generic work as a
186 shadow for a primitive procedure. If the primitive procedure
187 can't dispatch on its arguments, control is left over to the
188 generic. Normal wrong type arg errors will be generated until the
189 user has hung the first method on the primitive.
191 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
193 * procs.c, procs.h (scm_subr_p): New function (used internally).
195 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
197 * objects.c, objects.h (scm_primitive_generic): New class.
199 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
201 * print.c (scm_iprin1): Print primitive-generics.
203 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
204 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
206 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
207 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
208 primitives). NOTE: This means that it is now *required* to use
209 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
210 obscured representation that will be removed in the future anyway,
211 so backward compatibility is no problem here).
213 * numbers.c: Converted most numeric primitives (all but bit
214 comparison operations and bit operations) to dispatch on generic
218 Better support for applying generic functions.
220 * eval.c, eval.h (scm_eval_body): New function.
222 * objects.c (scm_call_generic_0, scm_call_generic_1,
223 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
227 Optimization of the generic function dispatch mechanism.
229 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
230 called scm_memoize_method instead of doing a second lookup.
232 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
237 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
238 scm_sysintern so that the binding connected with the subr name
239 isn't cleared when we give set = 0.
242 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
244 More transparent handling of ports with print states.
246 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
247 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
248 instead of a pair of a port and a print state. We'll need to cons
249 once extra in scm_printer_apply but the type system will be
250 cleaner, it will mix better with GOOPS, and, it will be even more
251 transparent to the user.
253 * print.c (scm_get_print_state): New procedure: Given an output
254 port, return the print state associated to it in the current print
255 chain, if one exists;
256 (scm_port_with_print_state): New procedure: Associate a
257 print-state with a port.
258 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
259 (scm_printer_apply): Wrap port and pstate as a smob;
260 (print_state_printer): Removed.
262 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
264 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
267 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
268 testing (otherwise the port-print-state trick won't be transparent
269 to the user; one example where this caused problems was in the
270 (ice-9 format) module).
272 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
274 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
275 SCM_UNSPECIFIED instead of the set value.
277 1999-08-20 James Blandy <jimb@mule.m17n.org>
279 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
281 * ports.h (enum scm_port_rw_active): New enum, containing
282 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
283 zero). The debugger knows about enums, but doesn't know about
285 (typedef scm_port): Declare rw_active member to be an enum
287 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
289 * ports.c (scm_add_to_port_table): Same.
290 * strports.c (st_flush, st_end_input): Same.
292 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
293 scm_must_realloc, and scm_done_malloc as appropriate.
295 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
297 * sort.c (quicksort): Added condition to protect the algorithm
298 from crashing the interpreter if the less predicate is buggy.
300 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
302 * fports.c (fport_write): fix line-buffering mode again.
303 (scm_open_file): recognise 'l' for line-buffering.
304 (scm_setvbuf): recognise _IOLBF for line-buffering.
306 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
308 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
311 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
314 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
316 * fports.c (fport_write): use memcpy instead of strncpy, in case
317 the data contains NUL.
319 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
321 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
323 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
324 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
325 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
326 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
327 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
328 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
329 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
330 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
331 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
332 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
333 scm_sym_ as prefix for symbols.
335 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
337 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
338 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
339 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
340 scm_sym_atcall_cc): Made global.
342 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
344 * eval.c (scm_sym_args): Made global.
346 * objects.c (scm_set_object_procedure_x): Disallow setting of
347 procedures for pure generic functions.
349 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
351 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
352 Scheme name from lseek to seek, but lseek was added recently so
353 it shouldn't be a big problem.
354 * ports.c, gdbint.c, ioext.c: changed callers.
356 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
358 * fports.c (fport_input_waiting): if select is used, return 1
359 instead of whatever FD_ISSET expands to. maybe it will be useful
360 to interpret the value from the input_waiting ptob procedure as a
361 lower bound on the number of bytes available.
363 * Mikael asked for a few names to be changed...
365 * ports.c (scm_make_port_type): take the write procedure as the
366 second argument instead of the flush procedure.
367 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
368 fflush -> flush, read_flush -> end_input, fclose -> close,
369 fill_buffer -> fill_input, ftruncate -> truncate,
370 input_waiting_p -> input_waiting.
372 * ports.c (end_input_void_port): was read_flush_void_port.
373 (scm_set_port_end_input): was scm_set_port_flush_input.
374 (scm_set_port_flush): was scm_set_port_write.
375 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
376 (scm_end_input): was scm_read_flush.
377 (scm_fill_input): was scm_fill_buffer.
378 (scm_flush): was scm_fflush.
379 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
380 (fport_end_input): was local_read_flush.
381 (fport_flush): was local_fflush.
382 (fport_close): was local_fclose.
383 (fport_truncate): was local_ftruncate.
384 (fport_seek): was local_seek.
385 (fport_free): was local_free.
386 (fport_fill_input): was fport_fill_buffer.
387 * strports.c (st_end_input): was st_read_flush.
388 (st_truncate): was st_ftruncate.
389 * vports.c: (sf_flush): was sfflush.
390 (sf_close): was sfclose.
391 (sf_fill_input): was sf_fill_buffer.
393 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
396 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
398 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
399 forms now contain the expressions to be dispatched upon instead of
400 depending on a surrounding lambda or let; Generic function
401 dispatch has been optimized; `apply' on a generic function now
402 works a little bit strangely. It uses a trick so that the type
403 dispatch code in SCM_CEVAL can be reused.
405 * objects.h, objects.c (scm_apply_generic_env): Added (used by
407 (scm_operator_p): Added.
408 (scm_sym_atdispatch): Added.
409 (scm_set_object_procedure_x): Modified to handle the new style
411 (scm_object_procedures): New debugging procedure.
413 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
415 * eval.c, eval.h (scm_sym_args): Added.
417 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
419 * feature.c, feature.h (scm_c_run_hook): Added.
421 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
422 cdrxnoap and loopnoap instead of begin and loop.
424 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
426 * ports.c (scm_putc, scm_puts),
427 * unif.c (scm_uniform_array_write): use scm_lfwrite.
428 * ports.c (scm_putc): change type of first argument from int to char.
430 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
432 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
433 SCM_IM_HASH_DISPATCH.
435 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
436 (scm_si_redfined, scm_si_hashsets): Moved.
438 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
439 flag which combines type and status info so that the class
440 redefinition protocol has zero cost during normal execution.
442 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
444 * ports.h (scm_ptob_descriptor): include a write procedure again.
445 it's more efficient for unbuffered fports (e.g., sockets.)
447 * ports.c (scm_puts): use ptob->write.
448 * vports.c (scm_make_sfptob): set write proc in ptob.
449 * strports.c (scm_make_stptob): set write proc in ptob.
450 * ports.c (write_void_port): new procedure.
451 * vports.c (sf_write): new procedure.
452 * ports.c (scm_lfwrite): use ptob->write.
453 * strports.c (st_write): new procedure.
454 * fports.c (fport_write): new procedure.
455 (scm_make_fptob): set write in ptob to fport_write.
456 * ports.h: prototype for scm_set_port_write.
457 * ports.c (scm_make_port_type): initialise ptob write procedure.
458 (scm_set_port_write): new proc.
460 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
462 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
463 until we've verified that it is actually a port. (Thanks to
466 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
468 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
469 code, particularly an unnecessary test (len != size, where len ==
470 size). (Was this leftovers from debugging code, or have I missed
473 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
474 size. (Thanks to James Dean Palmer.)
476 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
477 (Thanks to Lorentey Karoly.)
479 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
481 * eval.c (scm_m_expand_body): Use scm_cons_source.
483 * struct.c (scm_print_struct): Use vtable name.
485 * print.c (scm_init_print): Set name of print state type.
487 * stacks.c (scm_init_stacks): Set name of stack type.
489 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
491 * eval.c (SCM_CEVAL): Removed old implementation of internal
494 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
496 * debug.c, debug.h (scm_reverse_lookup): Added.
497 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
498 internal procedure definitions; Don't use scm_i_inner_name.
500 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
503 * eval.h: Added prototypes for multi language support functions.
505 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
506 improper lists in the low-level representation, since that will
507 cause a begin to be prepended at macro expansion.
509 * eval.c (scm_cons_source): Version of cons which copies source
510 properties from an existing cell.
511 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
513 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
514 procedure source before calling scm_unmemocopy instead of faking
517 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
519 Ported `internal defines' fix from SCM. Original ChangeLog entry:
521 1998-07-09 Radey Shouman <radey@colorage.com>
523 * eval.c (ceval_1): Modifications to allow rewriting of interal
524 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
525 body of which it is the CAR is macro expanded by m_expand_body,
526 which rewrites internal DEFINE.
528 (m_expand_body): Added.
530 (m_macroexp1): Added argument to control error checking:
531 m_expand_body may speculatively expand forms in the wrong
532 environments. Made argument number checks conditional on
535 (m_body): Added, error checks bodies and inserts the ISYM tokens.
537 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
540 (m_cond): (m_case): (m_quote): Modified to avoid destructively
541 changing their argument forms. Since m_expand_body
542 speculatively macro expands forms the process must be
545 (m_ident_eqp): Fixed to use proper environment.
547 (renamed_ident): Added DEFER_INTS_EGC.
549 Added prototypes for static functions.
555 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
556 is false, do not produce an error for unbound variables, return a
557 pointer to cell_undef instead.
559 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
563 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
564 destructively changing their argument forms. Since m_expand_body
565 speculatively macro expands forms the process must be reversible.
567 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
568 SCM_IM_LET introduced by named lets.
570 (scm_m_letstar): Use scm_m_body instead of bodycheck.
572 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
573 scm_letrec. scm_letrec1 does not check for a null binding and
574 takes an additional argument to specify the ISYM of the body. Use
575 scm_m_body instead of bodycheck.
577 (scm_m_let): Use scm_m_body instead of bodycheck.
579 (scm_m_expand_body, scm_macroexp): New.
581 (unmemocopy): Account for ISYMs introduced by scm_m_body.
583 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
584 check=1. Throw error for internal defined that have not been
585 rewritten by scm_m_expand_body.
587 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
588 Removed prototype for SCM_APPLY.
590 * tags.h: Added extern declaration of scm_isymnames.

596 * lang.c: New file: Beginning of multi-language support.
598 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
600 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
601 (scm_dynamic_wind): Added argument checking for the after guard so
602 that we don't add garbage on the dynwind chain.
603 (scm_swap_bindings): Added.
605 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
606 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
607 (scm_isymnames): New isyms for multi-language support.
609 * eval.c (scm_nil, scm_t): New symbols.
610 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
611 forms for multi-language support.

617 Renamed functions in the random function library interface
618 from scm_i_XXX --> scm_c_XXX.

627 scm_set_ptob_XXX --> scm_set_port_XXX.
629 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
631 * ports.c, ports.h (scm_make_port_type): New interface for
632 creation of port types (replaces scm_newptob). Just as for the
633 smobs, we need to separate the internal representation of smob
634 types from the interface, so that we easily can add new fields and
635 rearrange things without caring about backward compatibility.
636 This change was forced by the need in GOOPS to create classes
637 representing port types.
638 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
639 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,

645 (scm_prinport): Removed.
646 (scm_port_print): Added.
647 (scm_print_port_mode): Added.
648 (void_port_ptob, print_void_port, close_void_port, noop0):
649 Removed. Removed #include "genio.h" Added #include "objects.h",
652 * fports.c (prinfport): Moved code from ports.c.
654 (scm_fptob): Removed. Instead use new interface.

661 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
662 (scm_make_sfport): Added.

665 Instead provide specific directory printer.
667 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
669 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->

685 * filesys.c (scm_truncate_file): removed.
687 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
689 * readline.c, readline.h: Removed.
691 * objects.c, objects.h (scm_port_class): Added.
692 (scm_class_of): Look up port class in scm_port_class.

701 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
703 * init.c: Make sure that scm_post_boot_init_modules is called only
704 once. (Important when using a dumped image.; Thanks to Bernard
707 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
709 * guardians.c (scm_guardian_zombify): Separate scanning for
710 zombies from marking the pairs of the free list.
712 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
713 use the macros. (Thanks to Michael Livshin.)
715 * eval.c (scm_m_lambda): Let bodycheck check the body of the
716 lambda. Let your sins be purified by the blood of the lambda.
717 (Thanks to Eric Hanchrow.)
719 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
720 (Thanks to Valdis Kletnieks.)
722 Fixes for EMX from Mikael Ståldal.
724 * filesys.c: #include <io.h>, if we have it.
725 * scmconfig.h.in: Regenerated.
727 * stime.c (ftime): Delete declaration for this function --- let
728 the system supply it.
730 Cleanups from John Bley.
732 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
734 * gsubr.c: Don't include "gsubr.h" twice.
736 Cleanups for compilation on Irix 6, from David Kaelbling.
738 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
739 regex_t pointer. This is what the callers have, mostly.
740 (scm_regexp_exec): Don't forget to pass the `rx' argument to
741 scm_regexp_error_msg.
743 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
744 int. That way, if we get a warning on this line, it's more likely
745 that we're really missing bits we care about.
747 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
750 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
751 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
752 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
753 cast at all is more appropriate in every case. At the moment, we
754 assume everywhere that SCM is an integral type anyway.
756 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
758 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
759 read_pos after scm_fill_buffer.
761 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
764 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
765 fports.c (fport_fill_buffer): implement the interface change.
767 * ports.c (scm_fill_buffer): interface change: no longer increments
768 read_pos past the character that's returned. it seems clearer to
769 leave it to the caller to decide what to do (thanks Jim).
771 * vports.c (sf_fill_buffer): put the read char into the buffer
772 as well as returning it.
774 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

788 * ports.c (scm_ftruncate): throw error if offset works out negative.
790 * strports.c (st_flush): increase string size in blocks of
791 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
792 it's greater and reset read_buf_size.
793 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
794 to be maintained for output ports too (it holds the written
795 part of the string, while write_buf may have unwritten buffer
797 (st_truncate): rewritten.
798 (top of file): added a few notes.
800 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
802 Patch from Greg Badros:
803 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
804 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
805 (function pointer) argument to scm_make_gsubr and scm_make_subr
806 calls. This avoids warnings in C++ programs using guile-snarf.
808 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
810 * strports.c (st_grow_port): set pt->read_pos. set
811 pt->read_buf_size one less than pt->write_buf_size if there's
812 an unwritten char at the end of the string. similarly for
814 (st_resize_port): renamed from st_grow_port.
815 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
816 seek from read_end instead of write_end for SEEK_END.

934 * struct.c, struct.h:
936 In order to support different kinds of deallocation, a destructor
937 slot has been added to struct vtables. This allows for structs
938 containing pointers to other memory blocks.
940 (scm_struct_i_free): New hidden struct slot. Holds destructor for
941 instances to this vtable.
942 (scm_struct_free_0): New destructor: Doesn't deallocate data.

1062 scm_weak_vectors as the head of the chain.
1063 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1064 instead of stepping through an array.

1076 Fix from Gary Houston:
1077 * fports.c (local_seek): Signal an error if the seek fails.
1078 * ports.c (scm_lseek): Don't check return value of port's seek

1083 * strports.c (scm_call_with_output_string): Don't include the
1084 extra character at the end of the string in the result.
1086 * ioext.c (scm_read_line): Switch to reading properly.
1088 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
1089 scmsigs.c, strports.c, vports.c: Install the sources which
1090 actually correspond to the changes described below. I got the
1091 ChangeLog entries and the patch from two different places...
1093 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1095 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1096 it shows up as terrible performance, as we GC constantly.
1098 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1099 newline. A bit faster, and definitely hairier.
1100 (scm_read_line): Count newlines here instead.
1102 * strings.c (scm_take_str): New function.
1103 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1104 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
1105 scm_take_str, to avoid copying the string.
1107 Add some simple-minded support for line buffered ports.
1108 * ports.h (SCM_BUFLINE): New flag for ports.
1109 * init.c (scm_init_standard_ports): Request line-buffering on
1110 the standard output port.
1111 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1113 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1114 and there's a newline to be written, flush the port.
1116 Gary Houston's open-buffer port patches:
1118 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1120 * ports.c: (scm_lseek): clear buffers even if just reading current
1123 * fports.c (local_fclose): call local_fflush unconditionally.
1124 (various): don't use the scm_must... memory procs.
1126 1999-04-25 Gary Houston <ghouston@easynet.co.uk>
1128 * ports.h (scm_port): make read_pos a pointer to const.
1129 strports.c: take care of rw_active and rw_randow.
1130 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
1131 strports.c (scm_mkstrport): check that pos is reasonable.
1132 ioext.c (scm_ftell, scm_fseek): use lseek.
1133 (SCM_CLEAR_BUFFERS): macro deleted.
1134 ioext.c (redirect_port: use ptob fflush, read_flush.
1135 ports.h (scm_ptobfuns): add ftruncate.
1136 ports.c (scm_newptob): set ftruncate.
1138 ports.c (scm_ftruncate): new procedure.
1139 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
1140 strports.c (st_seek, st_grow_port): new procs.
1141 fports.h (scm_port): change size types from int to off_t.
1142 ports.c (scm_init_ports): initialise the seek symbols here
1143 instead of in ioext.c.
1144 strports.c (scm_call_with_output_string): start with an empty
1145 string, so seek and ftruncate can be used.
1147 gdbint.c: adjust string port usage.
1149 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1151 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1152 equivalent to fflush for the read buffer.
1153 * ports.c (scm_newptob): set read_flush.
1154 ports.c (void_port_ptob): set read_flush.
1155 fports.c (local_read_flush): new proc. add to ptob.
1156 strport.c (st_read_flush): likewise.
1157 vport.c (sf_read_flush): likewise.
1158 fports.h (struct scm_fport): remove random member. there's nothing
1159 left but fdes. leaving it as a struct to allow for future changes.
1160 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1161 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1162 ptob proc if the read buffer is filled.
1164 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1166 * ports.h (scm_port): add a rw_random member and replace
1167 reading and writing members with rw_active member.
1168 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1170 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1172 * ports.h (struct scm_port_table): add writing and reading members
1173 to replace write_needs_seek: it isn't good enough for non-fports.
1174 ports.c, ioext.c, fports.c: corresponding changes.
1175 (struct scm_port_table): give it a typedef and rename to scm_port.
1176 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1177 corresponding changes.
1179 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
1181 * ports.c (scm_newptob): bugfix: set seek member.
1182 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
1183 and generalised to all port types.
1185 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
1187 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1188 signals (it was only being done for handlers installed from Scheme).
1189 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1190 waiting for input caused an EINTR error from read.
1192 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1194 * ports.h (struct scm_port_table): make all the char members
1195 unsigned, so they convert to int without becoming negative if large.
1197 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1199 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1200 with threads enabled. rename this procedure to
1201 fport_wait_for_input and take a port instead of a fdes.
1202 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1204 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1205 get readline support working again: use fdopen to get FILE objects.
1207 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1209 * gc.c (scm_init_storage): install an atexit proc to flush the
1211 (cleanup): the new proc. it sets a global variable which can be
1212 checked by the ptob flush procs to avoid trying to throw
1213 exceptions during exit. not very pleasant but it seems more reliable.
1214 * fports.c (local_fflush): check terminating variable and if set
1215 don't throw exception.
1216 * CHECKME: that the atexit proc is installed if unexec used.
1218 * throw.c (scm_handle_by_message): don't flush all ports here.
1219 it still causes bus errors.
1221 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1222 and move to ioext.c.
1224 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1226 * ports.c (scm_char_ready_p): check the port buffer and call the
1227 ptob entry if needed.
1229 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1230 ptob initialisers. use it in char-ready
1232 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1234 * vports.c (sfflush): modified to write a char (since softports
1235 currently use shortbuf.)
1237 * fports.c (scm_standard_stream_to_port): moved to init.c and
1240 * init.c (scm_init_standard_ports): make stdout and stderr
1241 unbuffered if connected to a terminal. with stdio they
1242 were line-buffered by default.
1244 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1247 * ports.h (scm_ptobfuns): change fflush return to void.
1248 change flush proc definitions.
1250 * strports.c (scm_call_with_output_string): get size from
1251 buffer instead of port stream.
1252 (st_flush): new proc.
1254 * ports.h (struct scm_port_table): added write_end member,
1255 as an optimisation. set it where write_buf_size is set.
1257 * ports.h (struct scm_port_table): change stream from void *
1258 back to SCM. SCM presumably must be large enough to hold a
1259 pointer (and probably vice versa but who knows.)
1260 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1262 (scm_puts): rewritten
1263 * fports.c (local_ffwrite, local_fputs): removed.
1264 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)

1275 * ports.h (scm_ptobfuns): add seek function pointer.
1276 * fports.c: set it to local_seek, new procedure.
1279 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1280 use ptob for seek. take ptob instead of fport arg.
1282 * ports.h (struct scm_port_table): new member write_needs_seek,
1283 replaces reading member in fport struct.
1285 * vports.c (sfgetc): store the getted char into the buffer.
1286 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1287 the Scheme interface is still a procedure that gets a char.
1288 (scm_make_soft_port): set up the port buffer (shortbuf).
1290 * fports.c (local_fgetc, local_fgets): deleted.
1291 * strports.c (stgetc): likewise.

1295 * ports.c (scm_newptob): assign it.
1296 * strports.c (scm_mkstrport): set up the buffer.
1297 put just the string into the stream, not cons (pos stream).
1298 (stfill_buffer): new proc.
1300 * ports.h: fport buffer moved into port table: to be
1301 used for all port types.

1574 linking crashes on NetBSD. (Thanks to Ken Raeburn.)
1576 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1578 * numbers.c (isfinite): Define this macro if not defined: Return a
1579 non-zero value if X is finite. (From ISO C 9x standard.)
1580 (scm_inexact_to_exact): Bugfix: Don't pass NaNs to scm_dbl2big.
1581 (Thanks to Jon Trowbridge and Greg Harvey.)
1583 1999-03-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1608 (scm_system_module_env_p): Assume root environment is no lookup
1611 * debug.c, eval.c, evalext.c, gdbint.c stacks.c:

1621 * error.c (scm_wta): Pass SCM_LIST1 (arg) instead of SCM_EOL to
1622 scm_misc_error when pos is a string. This allows for dispatching

1632 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1634 Most of this batch of changes is about how to deal with extended
1635 types when an object system is loaded into Guile. A nice object
1636 system is capable of representing Guile's types as class objects.
1638 For example, we want a regular expression to be of class <regex>.
1639 But regular expressions are smobs which aren't under direct
1640 control of the object system, so there has to be some mechanism
1641 which informs the object system that a new class should be created
1642 which can represent the smob type. I call this a "wrapper class".
1644 * objects.c: #include "smob.h";
1645 (scm_class_keyword): Removed. (Class is automatically created by
1647 (scm_smob_class): Array of smob classes indexed by smobnum.
1648 (scm_make_extended_class): "Plugin" function pointer for creation
1649 of wrapper classes for smob and struct types.
1650 (scm_class_of): Handle compiled closures. (Currently regarded as
1652 Use scm_smob_class to handle smob types;
1653 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1654 through scm_smob_class;
1657 * smob.c (scm_newsmob): Also create a wrapper class if
1658 scm_smob_class has been initialized.
1660 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1661 type code and smobnum.
1663 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1664 (scm_struct_table): Weak key table with auxilliary information for
1665 struct types. Currently used for names and wrapper classes.
1666 (scm_struct_ihashq): Hash function for structs.
1667 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1668 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1669 for accessing names of vtables. The record implementation in
1670 boot-9.scm currently uses the setter to record the name of record
1671 types. When the object system is initialized, it can use this
1672 information to create wrapper classes with suitable names.
1673 (scm_init_struct): Allocate scm_struct_table.
1674 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1675 (struct tags are a finite resource and we might want to restrict
1676 the use of tags to vtables only. E.g., Goops only uses tags for
1678 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1680 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1683 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1684 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1685 Used for access of struct table entries.
1687 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1688 (scm_hash_fold): New procedure. Used to process all entries in a
1689 hash table (in no particular order).
1691 Argh! For the umpteenth time I got compilation errors because of
1692 the "intuitive" name `kw'. This has to have an end:
1694 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1695 "kw" --> "keywords" everywhere.
1696 (I doubt that this will cause big compatibility problems since the
1697 application interface is unaffected.)
1699 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1701 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1703 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1704 column inums to native form.
1706 Improvement of backtraces: Introduces a new stack narrowing
1707 specifier, #t, for the inner cut. (See further in the comments in
1708 stacks.c:narrow_stack ().)
1710 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
1711 (Used to flag certain system procedures which shouldn't turn up in
1714 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1715 modules which aren't "user" modules and the code of which
1716 shouldn't turn up in backtraces.)

1731 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1733 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1734 procedure throughout.
1736 * print.c (scm_iprin1): Removed extraneous space when printing
1737 procedure-with-setters.
1739 Entity and operator setter slots were introduced as a complement
1740 to the <procedure-with-setter> type in order to support entities
1741 and operators with setters in a reasonable and efficient way.
1742 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1745 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1758 directly through the instance.
1760 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1762 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1763 scm_struct_i_flags instead of scm_vtable_index_layout!
1765 * list.c (scm_list_star): New procedure.
1767 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1848 SYMB now point to const.
1850 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1852 * print.c (scm_iprin1): Use scm_procedure_name instead of
1853 scm_procedure_property for compiled closures.
1855 * tags.h (scm_tc7_pws): New procedure type. Four representations
1856 for procedure-with-setters were considered before selecting this
1859 1. A closure where the CODE and ENV slots are used to represent
1860 the getter and a new SETTER slot is used for the setter. The
1861 original getter is stored as a `getter' procedure property. For
1862 closure getters, the CODE and ENV slots contains a copy of the
1863 getter's CODE and ENV slots. For subr getters, the CODE contains
1866 2. A compiled closure with a call to the getter in the cclo
1867 procedure. The getter and setter are stored in slots 1 and 2.
1869 3. An entity (i.e. a struct with an associated procedure) with a
1870 call to the getter in the entity procedure and the setter stored
1871 in slot 0. The original getter is stored in slot 1.
1873 4. A new primitive procedure type supported in the evaluator. The
1874 getter and setter are stored in a GETTER and SETTER slot. A call
1875 to this procedure type results in a retrieval of the getter and a
1876 jump back to the correct eval dispatcher.
1878 Representation 4 was selected because of efficiency and
1881 Rep 1 has the advantage that there is zero penalty for closure
1882 getters, but primitive getters will get considerable overhead
1883 because the procedure-with-getter will be a closure which calls
1886 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1887 <procedure-with-setter>, but together with rep 2 it suffers from a
1888 three level dispatch for non-GOOPS getters:
1890 cclo/struct --> dispatch proc --> getter
1892 This is because the dispatch procedure must take an extra initial
1893 argument (cclo for rep 2, struct for rep 3).
1895 Rep 4 has the single disadvantage that it uses up one tc7 type
1896 code, but the plan for uniform vectors will very likely free tc7
1897 codes, so this is probably no big problem. Also note that the
1898 GETTER and SETTER slots can live directly on the heap, using the
1899 new four-word cells.
1901 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

2075 scm_debug_newcell return the new cell.
2076 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2077 taking the address of a place to store it as an argument.
2078 * gc.h (scm_debug_newcell): Change declaration.
2079 (Thanks to Greg Harvey.)
2081 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2083 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
2084 Replaces old names serial-array-copy! and serial-array-map!.
2086 * evalext.c (map-in-order): New name. Replaces serial-map.
2088 1998-12-05 Jim Blandy <jimb@totoro.red-bean.com>
2090 * smob.c (freeprint): New function.
2091 (freecell): Use it to print freed objects, for slightly easier
2094 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2096 * backtrace.c (display_frame): Made more robust. Doesn't throw an
2097 error if no source properties can be found for a frame. (Thanks
2098 to Christian Lynbech.)
2100 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2102 * objects.h: Removed slots direct_supers and direct_slots from the
2103 definitions of the rudimentary classes described by objects.h.
2105 * objects.c, objects.h (scm_entity_p): New procedure. Together
2106 with the predicates scm_procedure_p and scm_struct_p, this
2107 predicate makes it possible to differ between structs, entities
2110 * modules.c, modules.h (scm_resolve_module): New function.
2112 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2114 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2115 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2118 * objects.c (scm_entity_p): New procedure.
2120 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
2121 for asubrs, rpsubrs, lsubrs and lsubr_2s.
2123 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2125 * procprop.h (scm_i_procedure_arity): Added declaration.
2127 * procprop.c (scm_i_procedure_arity): Made global; New code to
2128 handle operators and entities.
2129 (scm_procedure_property): No need to call scm_procedure_p since
2130 scm_i_procedure_arity now does all necessary type checking.
2131 Added #include "objects.h".
2133 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2134 s_add_hook_x --> s_remove_hook_x.
2135 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
2136 Added #include "procprop.h"
2138 * feature.c, feature.h (scm_reset_hook_x): New procedure.
2139 (scm_make_hook): Optional argument defines number of arguments to
2141 (scm_make_named_hook): Take number of args as second arg.
2142 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2143 boot-9.scm for a while); First arg is the hook. The rest are
2144 arguments passed on to the hook procedures.
2146 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2148 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2149 scm_logbit_p): Do the computation in ulongs. This is not as nice
2150 as doing it in bignums, but at least it's good enough for
2151 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2153 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2154 subexpressions. (Thanks to Charbel Jacquin.)
2156 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2158 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2159 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2160 (scm_make_named_hook): New function.
2162 * feature.c: Added #include "eval.h".
2164 * modules.c (scm_make_module): Beautify the module.
2166 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2168 * modules.c, modules.h: New files: C interface to modules. (This
2169 is necessary in order to interface the object system to Guile
2170 properly. The guts of these modules will be replaced by the new
2171 module system in the future.)
2173 * init.c: Added #include "modules.h"
2174 (scm_boot_guile_1): Call scm_init_modules.
2175 (invoke_main_func): Call scm_post_boot_init_modules.
2177 * Makefile.am: Added modules.c, modules.x, modules.h.
2179 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2181 * procs.c: #include "objects.h"
2182 (scm_procedure_p): Return #t also on structs which are operators.
2184 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2185 <operator-metaclass> and <entity-class> to <standard-class>,
2186 <operator-class> and <entity> in order to conform with STKlos
2189 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2190 which isn't an operator.
2191 (SCM_APPLY): Ditto, but jump to badproc.
2193 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2195 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2196 Previously, structs implanted in code were interpreted as forms
2197 the operator of which was a gloc. We solve this by checking for
2198 the zero in the emulated vcell in the struct vtable. Since
2199 implanted structs always will look like forms with a gloc
2200 operator, execution will only be slowed down by maximally one
2201 extra test-and-branch per application.
2203 * evalext.c (scm_definedp): Removed check for isyms; Added a
2204 second optional argument: It is now possible to supply an
2205 evaluation environment in which to look for the symbol.
2207 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2209 * readline.c (scm_init_readline): Set
2210 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2212 * coop.c (coop_condition_variable_wait): Removed
2213 (coop_condition_variable_wait_mutex): Folded logic of
2214 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2215 prevent condvar signal lossage. Previously, another thread could
2216 start to run after unlocking the mutex but before putting the
2217 current thread on the wait queue. If that thread then would
2218 signal the first, the signal would be lost. (Thanks to Christian
2221 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2223 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2226 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2228 * objects.c (scm_i_make_class_object): Renamed from
2229 make_class_object; exported; error checking moved to
2230 scm_make_class_object and scm_make_subclass_object.
2231 (scm_make_class_object, scm_make_subclass_object): Use
2232 scm_i_make_class_object.
2233 (scm_make_subclass_object): Let the subclass have same metaclass
2236 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2238 * debug.c (scm_debug_options): Bugfix: Set the value of
2239 scm_stack_checking_enabled_p after setting debug options;
2240 #include "stackchk.h". (Thanks to Richard Polton.)
2242 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2244 * unif.c (scm_array_contents): removed unnecessary test for 0
2247 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2249 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2250 Replaced by macro `collect' in boot-9.scm.
2252 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2254 * eval.c (scm_copy_tree): Copy source properties if existent.
2256 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2257 don't, we may end up passing memoized source to a transformer.)
2259 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2261 * stack.c (get_applybody): Help function which lookups the first
2262 body form of the apply closure.
2263 (read_frames): Prevent the source of the first form of the apply
2264 closure from being recorded. This would only be confusing.
2266 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2267 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2269 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2271 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2273 (read_frames): Use SCM_MACROEXPP.
2275 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2277 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2278 don't contain interesting information since all arguments are
2279 present in the frame which applies the compiled closure anyway.);
2280 Skip the transformer application frames.
2282 * print.c (scm_iprin1): Print gsubrs as primitives.
2284 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2286 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2288 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2289 that we can identify these in a backtrace. (This change doesn't
2290 introduce any significant speed penalty.)
2292 * eval.c: Added note about `serial-map' using scm_map.
2294 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2295 readline options. They should reside in their own options array.
2297 * readline.c, readline.h (scm_readline_options,
2298 scm_readline_opts): Moved readline options here.
2300 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2302 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2303 SCM_ROCHARS instead of SCM_CHARS.
2305 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2306 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2308 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2310 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2311 This is quite important since the latter clears the
2312 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2313 every single character read...
2315 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2317 * print.c (scm_iprin1): Removed suspect looking (and indeed
2318 malevolent) semicolon after test for user supplied closure print
2319 procedure. (Thanks to Telford Tendys.)
2321 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2322 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2323 starting to search the list. Removed call to sloppy_mem_check.
2325 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2326 procedures: Same as scm_delq_x et al, but delete maximally one
2329 * options.c (scm_options, scm_init_options): GC-protect option
2330 values of type SCM. (Thanks to Telford Tendys.)
2332 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2334 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2335 make sure that there always is a "real" scm_lookupcar.
2337 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2339 * read.c, read.h (scm_read_opts): New read options
2340 "history-length" and "history-file".
2341 (scm_read_options): Stifle history to history length.
2343 * readline.c (scm_read_history, scm_write_history): New procedures.
2345 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2347 * eval.h (scm_macro_eval_x): Removed declaration.
2349 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2350 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2351 Renamed and made global.
2353 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2354 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2356 * evalext.c, evalext.h: New files. Contain non-R5RS things
2357 having to do with evaluation.
2359 * evalext.c (scm_serial_map): New procedure: Version of `map'
2360 which guarantees that the procedure is applied to the lists in
2362 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2363 returns a list of the results of the body forms instead of the
2364 result of the last body form.
2365 (scm_definedp, scm_m_undefine): Moved from eval.c
2367 * evalext.h (scm_m_sequence_to_list): Added declaration.
2369 * macros.c, macros.h: New files.
2370 (scm_procedure_to_syntax, scm_procedure_to_macro,
2371 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2372 scm_macro_name, scm_macro_transformer): Moved from eval.c
2373 (scm_make_synt): Moved from eval.c
2375 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2377 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2380 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2382 * debug.c, print.c: Added #include "macros.h".
2384 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2386 This change adds the ability to use `unread-char' multiple times
2387 without interspersed reads and adds the new procedure
2388 `unread-string'. The change is optimized for the common case of
2389 unreading a single character. This is also the reason behind the
2390 choice to store characters in the port itself: in most cases no
2391 extra malloc is required.
2393 The amount of code in some macros in ports.h has been increased to
2394 the extent that they would fit better as C functions, but, since
2395 this code belongs to the port representation, such functions
2396 should be placed in ports.c which would cause calls back and forth
2397 between ports.c and genio.c. That is not good for performance.
2398 Also, keeping them as macros allows the compiler to do some
2399 optimizations which are needed to make the current interface
2400 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2402 One benchmark (Guile startup time) indicates an increase of
2403 loading speed of 1%. Another (reading (using `read') boot-9.scm
2404 10 times) shows no change in performance.
2406 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2407 made to find a beautiful solution.)
2409 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2410 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2411 character. (SCM_CLRDY clears all.)
2412 (SCM_N_READY_CHARS): New macro: Returns number of unread
2413 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2414 (struct scm_port_table): New fields: `entry' contains port table
2415 index, `cp' points to last unread char, `cbuf' is the buffer for
2416 unread chars, `cbufend' points after end of the character buffer.
2418 * ports.h, ports.c (scm_unread_string): New procedure.
2419 (scm_grow_port_cbuf): New function.
2421 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2423 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2424 to read unread characters. Use SCM_TRY_CLRDY instead of
2427 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2429 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2431 * genio.c, genio.h (scm_ungets): New function.
2433 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2436 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2438 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2439 declarations. (Thanks to Russ McManus.)
2441 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2443 * numbers.c (num2long): As a software archeologist, I'm proud of
2444 this finding! :) Preliminary dating suggests an almost 4 year old
2445 remnant from the SCM ancestor. The sample has been removed from
2446 the finding site and is now safely stored in the repository.
2448 * numbers.h: Removed prototype for num2long.
2450 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2452 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2453 array as second arg.
2454 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2455 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2456 * gh.h: Updated and added prototypes.
2458 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2460 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2462 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2464 * guile-snarf.in: Never generate an empty file. (Thanks to
2467 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2468 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2469 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2470 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2471 gh_new_procedure5_0): Specify argument types, to appease C++
2472 compilers. (Thanks to Brad Bowman.)
2474 Bug reports from Russ McManus:
2475 * guile-snarf.in: If the CPP environment variable is set, use that
2476 as the C preprocessor, instead of the preprocessor autoconf
2478 * snarf.h (SCM_PROC): Cast the function pointer passed to
2479 scm_make_gsubr, to satisfy C++.
2481 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2482 Use the handler passed, instead of ignoring it and using
2483 gh_standard_handler. (Thanks to Etienne Bernard.)
2485 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2487 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2490 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

2510 * script.c (scm_compile_shell_switches): Define
2511 use-emacs-interface in the root module, so the repl code can see
2512 it. See today's change to top-repl in ice-9/boot-9.scm.
2514 * filesys.c (set_element, get_element): Make sure that `element'
2515 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2516 Boekemeier and Jorgen "forcer" Schaefer.)
2518 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2520 * chars.c (scm_charnames): In ASCII character name table, make
2521 newlines print as #\newline by default, not #\nl.
2523 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2524 alphabetical order. Oh thrills. But it helps me know how far
2525 along in the compilation I am.
2526 * Makefile.in: Regenerated.
2528 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2530 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2531 #bytes(...) to #y(...), and syntax for short vectors from
2532 #short(...) to #h(...). This may seem nutty, but, like the other
2533 uniform vectors, byte vectors and short vectors want to have the
2534 same print and read syntax (and, more basic, want to have read
2535 syntax!). Changing the read syntax to use multiple characters
2536 after the hash sign breaks with the conventions used in R5RS and
2537 the conventions used for the other uniform vectors. It also
2538 introduces complexity in the current reader, both on the C and
2539 Scheme levels. (The Right solution is probably to change the
2540 syntax and prototypes for uniform vectors entirely.)
2542 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2544 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2545 (Thanks to Jorgen "forcer" Schaefer.)
2546 * ports.h (SCM_NOFTELL): New flag.
2547 * fports.c (local_fgets): If it's set, use the generic fgets.
2548 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2550 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2552 * script.c (scm_compile_shell_switches): Add handling of -q switch
2553 (inhibit loading of user init file).
2554 (scm_shell_usage): Add usage text for -q switch.
2555 (scm_compile_shell_switches): Always load user init file first if
2556 it is loaded at all.
2558 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2560 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2561 and is now broken under NetBSD. I can't fathom what it's trying
2562 to do, so I've replaced it with something that I do understand,
2563 which seems to work, and which isn't broken on NetBSD. "Progress?
2564 You Decide." (Thanks to Perry Metzger.)
2566 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2567 signed/unsigned comparison.
2569 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2571 Warning fixes from Greg Harvey:
2572 * unif.c (scm_array_set_x): initializer for pos
2573 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2574 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2575 initializers for field_type, since EGCS so desparately wants to
2577 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2578 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2579 when GUILE_DEBUG is defined.
2580 * dynwind.h (scm_wind_chain): Same.
2581 * ports.h (scm_pt_size, scm_pt_member): Same.
2582 * print.h (scm_current_pstate): Same.
2583 * procs.h (scm_make_cclo): Same.
2585 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2587 Handle short and long long uniform arrays properly. (Thanks to
2589 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2590 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2591 scm_tc7_llvect (long long vectors).
2593 Change the way libguile and boot-9.scm are timestamped, to try to
2594 get rid of these spurious mismatch warnings. Now both
2595 libguile/versiondat.h and ice-9/version.scm are generated directly
2596 by the configuration process, rather than having version.scm
2597 generated directly, and libguile/versiondat.h generated by the
2598 Makefile, which is generated by configure. It seems that
2599 sometimes the Makefile would change, but versiondat.h depends on
2600 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2601 * Makefile.am (versiondat.h): Target removed; this is generated
2602 directly by the configure script now.
2603 (BUILT_SOURCES): Remove versiondat.h.
2604 * versiondat.h.in: New file, transformed by the configure script
2606 * Makefile.in: Regenerated.
2608 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2609 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2610 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2611 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2612 if we want to use them in a header file some day, we can. (Thanks
2613 to Michael Livshin.)
2615 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2616 SCM numbers, so we won't have rollover problems; the range of a
2617 signed long in milliseconds is about 25 days. (Thanks to Karl
2620 Don't redefine sleep and usleep; fix this problem now.
2621 * coop.c (sleep, usleep): Remove declarations; we don't use or
2622 redefine these any more.
2623 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2624 job of usleep and sleep in a thread-friendly way. We can use
2625 these in the rest of Guile. Define versions for systems both with
2626 and without iselect.
2627 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2628 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2629 we're just using it, not redefining it, we can use a K&R style
2631 (sleep): Declare this, too, if the system hasn't.
2632 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2633 scm_uthread_sleep if they're available; otherwise, just call the
2635 * scmconfig.h.in: Regenerated.
2637 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2639 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2641 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2643 * threads.c: Doc fix.
2645 The argument type of usleep varies from system to system,
2646 as does the return type. We really shouldn't be redefining usleep
2647 at all, but I don't have time to clean that up before the 1.3.
2648 release. It's on the schedule for afterwards. (Thanks to Julian
2650 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2652 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2653 * scmconfig.h: Regenerated.
2655 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2656 right way to handle system variation. Autoconf's approach is the
2658 * simpos.h (scm_software_type): Declaration deleted.
2660 * script.c (scm_find_executable): Don't test if unix is #defined
2661 here; first, NetBSD doesn't #define it, and second, it's the wrong
2662 way to go about these things. (Thanks to Perry Metzger.)
2663 (dld_find_executable): Delete this MSDOS support code. This isn't
2664 the way we want to support this; it needs to be rethunk at a
2667 * genio.c (scm_do_read_line): Don't just politely check that the
2668 line was either non-empty or EOF. Abort if it's empty and not
2671 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2673 * scmconfig.h.in: Regenerated.
2675 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2678 * genio.c (scm_do_read_line): Count lines correctly when the file
2679 doesn't end in a newline.
2681 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2683 * genio.c (scm_do_read_line): Maintain the line count correctly.
2684 (Thanks to Harvey J. Stein and Greg Harvey.)
2686 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2689 * numbers.c (big2str): Protect t from garbage collection until
2690 we're done. (Thanks to Gary Houston.)
2692 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2694 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2696 * Makefile.in: Regenerated.
2698 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2699 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2702 Do magic to mix reads and writes on stdio FILE-based ports.
2703 (Thanks to Christian Lynbech.)
2704 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2706 (pre_read, pre_write): New functions.
2707 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2708 local_fputs): Call them.
2709 (local_fflush): Mark the port as ready for reading and writing.
2710 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2711 flags on new port objects. This might not be accurate --- who
2712 knows what state the FILE * is in when we get it --- but it won't
2713 do extraneous calls to fflush or fseek, so it's no worse than the
2714 behavior before this change.
2715 * ports.h: Add comment.
2717 Centralize the creation of port objects based on stdio FILE * in
2718 fports.c; don't just throw them together anywhere.
2719 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2720 what the rest of Guile wants. Don't set the revealed count;
2721 that's only appropriate for stdin, stdout, stderr.
2722 (scm_standard_stream_to_port): This function does set the revealed
2724 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2725 not scm_stdio_to_port.
2726 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2727 * fports.c (scm_open_file): Same.
2728 * posix.c (scm_pipe): Same.
2729 * socket.c (scm_sock_fd_to_port): Same.
2730 * ioext.c (scm_fdopen): Same.
2731 (scm_freopen): Moved from here to...
2732 * fports.c (scm_freopen): ... here. This is really something that
2733 munges the internals of an fport, so it should go here.
2734 * fports.h (scm_stdio_to_port): Adjust prototype.
2735 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2736 * ioext.h (scm_freopen): Prototype removed.
2738 * filesys.c (set_element, get_element): This can work on both pipe
2739 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2742 * scmconfig.h.in: Regenerated.
2744 Change the definition of the functions in scm_ptobfuns so that
2745 they get passed the port object, not the port's stream.
2746 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2747 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2748 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2749 Pass the port itself to the scm_ptobs function.
2750 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2751 scm_generic_fgets): Same.
2752 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2753 getc_void_port, fgets_void_port, close_void_port): Just change the
2754 argument names; these functions don't really do anything.
2755 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2756 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2757 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2758 Also, use prototyped definitions, and get rid of the extra
2760 (scm_fptob, scm_pipob): We don't need casts here any more.
2761 * strports.c (prinstpt): Use prototype declarations.
2762 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2763 and use SCM_STREAM to get the string info. Also, use prototyped
2764 definitions, and get rid of the extra declarations.
2765 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2768 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2769 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2771 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2772 scm_fgets, for consistency.
2773 (scm_fptop, scm_pipob): References updated.
2775 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2777 Include the source location in error messages for scripts.
2778 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2779 stack is still there when we catch the error.
2780 * throw.c (handler_message): If we are handling an error with a
2781 message, then put together the proper arguments and call
2782 scm_display_error, instead of scm_display_error_message. That
2783 displays source location, if it can find it.
2785 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2787 * gc.c (scm_unprotect_object): Change this so that calls to
2788 scm_protect_object and scm_unprotect_object nest properly.
2789 (scm_protect_object): Doc fixes.
2791 * strings.c (scm_string_set_x): Require the argument to be a
2792 writable string, not a substring or a symbol.
2793 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2794 (Thanks to John Redford and Charbel Jacquin.)
2796 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2798 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2800 * eval.c (safe_setjmp): Remove this misunderstanding.
2801 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2804 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2806 * libguile.h: Mark these as C declarations, for compilation by C++
2809 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2810 __cplusplus clause. I seriously doubt this ever worked the way
2811 the author seems to have intended.
2813 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2815 Utterly needless cleanups to hopelessly messy code.
2816 * ports.c: Doc fixes.
2817 (scm_fflush): Moved to ...
2818 * genio.c (scm_fflush): ... here, amongst all the other port
2819 method invocation functions.
2820 * genio.h, ports.h: The prototype moves too.
2822 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2824 * backtrace.c (display_error_body): The current frame does not
2825 always have a parent frame; consider a function called directly
2826 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2829 * alloca.c (alloca): Undo yesterday's changes, and simply call
2830 malloc directly for storage, and abort if we don't get what we
2831 want. The situation is much simpler --- just call malloc. Emacs
2832 has bizarre/evil requirements (signal handlers might malloc unless
2833 you set this global flag, so you have to set the flag around all
2834 calls to malloc) which we are certainly not going to conform to,
2835 so we can do the simple and obvious thing.
2837 * coop.c (coop_condition_variable_wait): Make this function
2838 static. It's only useful internally --- you should never just
2839 wait on a condition variable.
2840 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2842 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2844 * unif.c (scm_array_set_x): Accept any kind of number as an
2845 element for a uniform vector of doubles. This is more consistent
2846 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2848 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2849 works; I can't conveniently test it myself. (Thanks to Dvid
2850 Tillman for the bug report.)
2852 * init.c: Doc fixes.
2854 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2855 from here, not from scm_compile_shell_switches (which is a pretty
2856 dumb place to do it).
2857 (scm_load_startup_files): New function.
2858 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2859 * script.c (scm_compile_shell_switches): Don't load the startup
2861 (scm_ice_9_already_loaded): Variable moved.
2862 * init.c (scm_load_startup_files): Prototype for new function.
2863 * gh_init.c (gh_enter): Doc fix.
2865 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2867 Some anti-warning changes from Greg Harvey.
2868 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2869 warnings when it doesn't understand our NORETURN declarations in
2871 * posix.c (scm_mknod): Similar.
2873 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2875 * posix.c (scm_getpwuid): If we can't find an entry, return our
2876 own message, instead of using scm_syserror --- the getpwMUMBLE
2877 functions don't set `errno' to anything interesting.
2879 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2881 Get rid of warnings from the cooperative threading system.
2882 * threads.h (scm_single_thread_p, scm_yield,
2883 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2884 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2885 scm_wait_condition_variable, scm_signal_condition_variable): Add
2886 prototypes for these Scheme-visible functions.
2887 * coop-defs.h (coop_next_runnable_thread,
2888 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2889 Prototypes for these here, even though they're from iselect.c.
2890 (coop_condition_variable_wait, coop_join): Add prototypes.
2891 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2892 scm_threads_free_condvar): Make these smob functions static.
2893 * coop-threads.h (coop_init): Give this a real prototype.
2894 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2895 (coop_next_runnable_thread): No need to provide prototype; it's in
2898 * scmconfig.h.in: .detarenegeR
2900 * iselect.c, threads.c: Doc fixes.
2902 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2904 * Makefile.in: Regenerated with a patched automake, to get
2905 dependency generation right when using EGCS.
2907 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2908 warning. (Thanks to Robert Pluim.)
2910 * inet_aton.c (inet_aton): Reassure the compiler that the
2911 arguments to the <ctype.h> macros are all unsigned characters, not
2914 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2916 Getting rid of more warnings...
2917 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2918 today's change to ../configure.in.
2919 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2920 * scmconfig.h.in: Regenertaded.de.,.__
2921 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2922 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2925 * readline.c: Doc fix.
2926 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2927 * readline.h (scm_filename_completion_function): Add prototype.
2928 (scm_init_readline): Make this into a prototype.
2930 * readline.c (scm_filename_completion_function): Use SCM_PROC to
2931 declare this, instead of calling scm_make_subr manually.
2933 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
2935 * readline.h (scm_init_readline): Add prototype for this.
2936 (scm_init_readline): Make this a real prototype.
2938 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
2940 Warning fixes from Maciej Stachowiak:
2941 * backtrace.h (scm_display_application, scm_backtrace): Add
2943 * debug.c (scm_m_start_stack): Make this function static.
2944 * fluids.h (scm_fluid_p): Add prototype.
2945 * procprop.c (scm_i_procedure_arity): Make this function static.
2946 * regex-posix.c (scm_regexp_error_msg): Make this function static.
2947 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
2948 * root.h (scm_dynamic_root): Add external prototype.
2949 * scmsigs.h (scm_usleep): Add external prototype.
2950 * script.h (scm_init_script): Use prototype, not K&R decl.
2951 * stacks.h (scm_stack_id): Add external prototype.
2952 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
2954 1998-09-30 Mark Galassi <rosalia@cygnus.com>
2956 * gh.h: took out the definitions of vset and vref, since they are
2957 replaced by the proper vector routines that correspond to the R4RS
2960 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
2962 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
2963 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
2964 third argument, a C expression that should result in a SCM value,
2965 which is used to initialize the variable. Reimplemented
2966 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
2969 * version.h (scm_libguile_config_stamp): Add prototype.
2970 (From Maciej Stachowiak.)
2972 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
2974 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
2975 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
2977 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
2979 * print.c (scm_iprin1): Rather than having one i, and using it in
2980 several places, declare a fresh i local to each block where it is
2981 used, and give it a signedness appropriate to its use in each case.
2982 (scm_iprlist): Same.
2984 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
2985 comparison warnings.
2987 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
2988 signed/unsigned clashes.
2990 * posix.h (scm_tmpnam): Added prototype.
2992 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
2993 scm_make_subclass_object): Add external prototypes.
2995 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
2996 comparison is okay here.
2998 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3000 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3001 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3003 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3006 * load.c (swap_port): Make this function static.
3008 * load.c (scm_search_path): Make max_path_len and max_ext_len
3009 unsigned, since they're compared against string sizes.
3011 * load.c (init_build_info): Make i unsigned.
3013 * ioext.h (scm_read_line): Add prototype.
3015 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3016 scm_hash_fn_remove_x): Make hash bucket index local variable k
3017 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3018 accurately as possible.
3020 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3021 comparisons, and range checking to make sure those casts are
3024 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3025 signed/unsigned comparisons.
3027 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3028 avoid signed/unsigned comparisons.
3029 * smob.h (scm_numsmob): Change extern declaration to match.
3031 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3032 avoid signed/unsigned comparisons.
3033 * ports.h (scm_numptob): Change extern declaration to match.
3034 (scm_current_load_port, scm_set_port_line_x,
3035 scm_set_port_column_x): New prototypes.
3037 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3038 test code, and it causes warnings.
3040 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3041 gh_uniform_vector_ref): Added prototypes.
3043 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3044 debugging support unconditionally. That's backtrace.c, stack.c,
3045 debug.c, and srcprop.c.
3046 (EXTRA_libguile_la_SOURCES): Omit those from here.
3047 * Makefile.in: Regenerated.
3049 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3051 * options.c (scm_options): Bugfix: Allow empty list of options!
3053 * debug.c, debug.h (scm_single_step): Removed.
3054 (scm_with_traps): New procedure. This procedure could easily be
3055 written in Scheme but needs to be highly optimized.
3057 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3059 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3060 Check SCM_TRAPS_P before trapping.
3062 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3064 Changes to avoid signed/unsigned comparison warnings.
3065 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3066 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3067 so they can have appropriate types for each application. Make i
3068 signed. Use initializers in some spots. I'll probably pay for
3070 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3071 (scm_must_realloc): Make nm unsigned.
3072 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3073 (scm_init_storage): Use prototype-style definition, and make the
3075 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3076 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3078 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3079 avoid signed/unsigned comparison warnings, and because the return
3080 value of readlink may be -1. Don't bother casting the third
3081 argument to readlink.
3083 * filesys.c (scm_dirname, scm_basename): Move these to their own
3084 page, at the end of the file.
3085 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3087 * eval.h (scm_eval_options_interface): Add external prototype for this.
3088 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3090 * eval.c (scm_lookupcar1): Make this static.
3092 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3093 Make these prototype declarations, not K&R-style.
3095 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3096 unsigned comparison warning.
3098 * appinit.c: File removed. It had a single function in it, empty,
3099 whose reason for existence is explained in no documentation or
3100 comment. I think it's there as a default for some Tcl-style
3101 initialization, but Tcl abandoned that approach a while ago.
3102 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3103 (BUILT_SOURCES): Remove appinit.x.
3104 * Makefile.in: Regenerated.
3106 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3108 * Makefile.in: Regenerated using the last public version of
3109 automake, not the hacked Cygnus version.
3111 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3113 Remove Totoro kludge.
3114 * Makefile.in, scmconfig.h.in: Regenerated.
3115 * init.c, readline.c: Don't check if TOTORO is #defined.
3117 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3119 * Makefile.am: Adjust for new thread configuration system.
3120 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3121 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3123 (THREAD_LIBS): Definition deleted; automake will generate such
3124 things automatically.
3125 * Makefile.in: Regenerated.
3127 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3129 Simplify smob and port marking; set the mark bit in the generic
3130 marking code, and make marker routines only responsible for
3131 turning up outgoing pointers.
3132 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3133 before calling the marking function. Don't call the marking
3134 function if it's zero.
3135 * markers.c (scm_mark0): Just return #f. This function isn't
3136 necessary at all now, but it's harmless to call it. We'll leave
3137 it in so other folks' code doesn't croak at link time.
3138 (scm_markcdr): Don't call SCM_SETGC8MARK.
3139 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3140 * dynl.c (mark_dynl_obj): Same.
3141 * root.c (mark_root): Same.
3142 * srcprop.c (marksrcprops): Same.
3143 * unif.c (markra): Same.
3144 * variable.c (scm_markvar): Same.
3145 * ports.c (scm_markstream): Same.
3146 (void_port_ptob): Specify zero for our marking function.
3147 * debug.c (debugobjsmob): Same.
3148 * dynwind.c (guardsmob): Same.
3149 * filesys.c (dir_smob): Same.
3150 * fluids.c (fluid_smob): Same.
3151 * fports.c (scm_fptob, scm_pipob): Same.
3152 * mallocs.c (mallocsmob): Same.
3153 * regex-posix.c (regex_t_smob): Same.
3154 * smob.c (freecell, flob, bigob): Same.
3155 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3156 * throw.c (jbsmob, lazy_catch_funs): Same.
3158 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3160 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3161 scm_copy_tree on code in order not to let memoized code to leak
3162 out. Thus, scm_copy_tree needs to copy vectors as well since
3163 quasiquote can introduce evaluated code also inside vector
3166 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3168 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3170 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3171 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3174 * unif.c: Say that ivect and uvect are of type signed and unsigned
3175 long instead of int in commentary so that it correctly describes
3178 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3180 * stime.c: Removed declaration of strptime. (It should be
3181 declared by the system headers. If it turns out that some systems
3182 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3184 * stime.h: Renamed TIMEH --> STIMEH
3186 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3187 to increase portability, don't use structure assignment.
3188 (Thanks to Nicolas Neuss.)
3190 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3192 (finalize_fd_sets): Added empty statement after last case label.
3193 (Thanks to Nicolas Neuss.)
3195 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3198 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3200 * init.c, readline.c: OK, I won't have these readline.x bug
3201 reports anymore. We've had them since April. The current reason
3202 is a completely unintelligible failure of totoro.red-bean.com to
3203 do the test for rl_getc_function in libreadline correctly. This
3204 kludge overrides the test if we're on totoro so that the snapshot
3205 generation process can work.
3207 * readline.c: Define a strdup replacement if not existent on system.
3209 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3211 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3212 This change makes scm_make_vector R5RS compatible. We cannot keep
3213 the third argument since people want to be able to deduce the form
3214 of the C function call only by looking at R5RS. (At the same time
3215 we have removed some unnecessary complexity!)
3217 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3218 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3219 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3220 argument in call to scm_make_vector.
3222 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3224 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3225 This macro is useful in applications.
3227 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3229 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3230 (scm_parse_path, scm_search_path): New Scheme level procedures.
3232 * load.h (scm_internal_parse_path, scm_parse_path,
3233 scm_search_path): Declared.
3235 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3237 * filesys.c (dirname, basename): New procedures.
3239 * init.c (scm_boot_guile_1): Removed condition around
3242 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3243 new data type (guards) for representation of C level guards and
3244 data on the wind chain.
3245 (scm_internal_dynamic_wind): New function.
3247 * dynwind.h: Declare scm_internal_dynamic_wind.
3249 * root.h (scm_root_state): Added scm_cur_loadp.
3251 * root.c (mark_root): Added comment about cur_loadp.
3253 * load.c: #include "dynwind.h";
3254 (scm_primitive_load): Use scm_inner_dynamic_wind to update
3257 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3259 * ports.c (current-load-port): New procedure.
3261 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3263 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3264 not a tty, return #f.
3266 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3267 to Julian Satchell and Roland Kaufmann.)
3269 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3270 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3272 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3274 * debug.h, debug.c (scm_start_stack): New function. Implements
3275 the guts of old scm_m_start_stack.
3277 * debug.c (scm_m_start_stack): Use scm_start_stack.
3279 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3280 start_stack and restart_stack. (These have static scope.)
3282 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3284 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3285 readline functions to come in release 2.3. (Thanks to Chet
3287 (handle_errors): Use the above functions.
3289 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3291 * readline.c: Improvements for readline support: Handle errors
3292 better; Implement before-read-hook.
3294 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3296 * init.c (scm_boot_guile_1), readline.c: Test for
3297 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3298 assure that we have version >= 2.1.)
3300 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3302 * readline.c (scm_readline): Defer interrupts while we're calling
3305 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3306 away the string to add_history.
3307 (completion_function): Do completion for readline. (Thanks to
3309 (scm_filename_completion_function): New procedure: Filename
3311 (current_input_getc): New function. Use this one instead of
3312 standard getc from readline.
3314 * throw.c, throw.h (scm_handle_by_throw): New function: This
3315 handler throws errors to next handler on the dynwind chain.
3317 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3319 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3322 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3324 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3326 (scm_procedure_properties): Modified to return arity together with
3328 (scm_procedure_property): Added the read-only property `arity'.
3329 (scm_set_procedure_property_x): It is an error to set the `arity'
3332 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3333 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3335 * procprop.h (scm_sym_arity): New symbol.
3337 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3338 to set the dispatch procedure of an operator or entity object.
3340 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3341 Made procedure slots read-only.
3343 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3344 scm_tcs_cons_gloc case in zero args switch; Fixed args
3345 construction for operators in scm_tcs_cons_gloc case in two args
3348 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3350 * fluids.c: Removed use of assert.h (in order to avoid
3353 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3355 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3357 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3358 change makes the evaluator safer at the cost of evaluation speed.
3359 It handles the case when the user has added a non-immediate
3360 improper end of the application form, e.g., `(+ 0 . x)'.
3361 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3362 minimize the extra cost as much as possible. The new code is
3363 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3364 problem with structs planted directly in the code (e.g. by a
3365 macro). This no longer causes segmentation fault. (Thanks to
3368 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3369 arg `proc' in order to be able to throw errors; New argument
3372 * Removed extra #include "debug.h"
3374 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3376 * scmsigs.c: Declare usleep as returning void on some systems.
3377 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3380 * coop.c (usleep): Return void on some systems.
3382 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3384 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3386 * coop.c: Changed return type of usleep to int.
3388 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3389 isn't found in the OS.
3391 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3392 isn't enabled. (Thought that I had made this change ages ago...)
3394 * iselect.c: Declare bzero if not defined by OS.
3396 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3398 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3399 condition. (Thanks to John Tobey.)
3401 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3402 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3405 * __scm.h: Start the long-term project of moving to POSIX threads.
3406 Phase 1: Classification of all critical sections.
3407 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3408 for A sections. (See comments in __scm.h for details.)
3410 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3411 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3413 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3415 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3416 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3417 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3418 dependencies on $(srcdir)/Makefile.in
3419 $(top_builddir)/config.status in order to avoid circularity.
3421 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3422 from argc if argc was 0 initially.
3424 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3425 in generation of libpath.h.
3427 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3429 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3430 libguile from 2 to 3.
3432 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3434 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3436 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3438 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3439 scm_set_port_column_x, scm_port_filename,
3440 scm_set_port_filename_x): Removed optional arguments. Added
3441 proper argument checking.
3443 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3444 stack size in machine words.
3446 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3447 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3448 to Ole Myren Röhne.)
3450 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3452 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3453 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3455 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3458 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3459 procedure apply: Copy argument lists before pushing them unto the
3460 environment so that the environment won't get mutated due to
3461 manipulation of procedure arguments. This should perhaps be
3462 regarded as a temporary solution until someone finds a more
3463 efficient one. (Thanks to Maciej Stachowiak.)
3465 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3467 * script.c (scm_compile_shell_switches): Use "guile" as default
3468 zero arg if argc is NULL.
3470 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3472 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3473 is zero. (Thanks to Dirk Herrmann.)
3475 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3477 * ports.c (scm_add_to_port_table): First line is now line 0
3478 (was 1). (Interface changed according to suggestion by Per
3481 * backtrace.c (display_header): Add 1 to line and column numbers
3482 when presenting them to the user.
3484 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3485 from debug.c --> eval.c
3487 * eval.h, eval.c (scm_eval_options_interface): New options
3489 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3490 i.e. stacks for new threads.
3492 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3494 * eval.c (unsafe_setjmp): Removed with #if 0.
3496 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3499 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3500 to avoid compiler warnings.
3502 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3504 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3506 * throw.c (handler_message): Print message on current error port
3507 instead of default error port. (Thanks to Maciej Stachowiak.)
3509 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3511 * ports.c (scm_add_to_port_table): allocate in units of
3512 struct scm_port_table *, not struct scm_port_table.
3513 * posix.c (scm_close_pipe): remove the port from the port table
3515 Thanks to Rob Engle for both fixes.
3517 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3519 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3520 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3522 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3524 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3526 * backtrace.c (display_error_body, display_backtrace_body),
3527 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3528 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3529 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3530 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3533 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3534 don't receive the jmpbuf arg anylonger.
3535 (scm_catch): Don't accept a #f tag.
3536 (scm_throw): Check that key is a symbol.
3537 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3539 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3541 * async.c (async_pending): Removed declaration.
3543 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3545 * dynwind.c (scm_wind_chain): New debug function.
3547 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3548 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3549 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3550 extra layer of functions around the body and handler of a thread.
3551 This extra layer makes sure that the handler is called in the
3552 dynamic context of the surround (= empty dynwind list), but under
3553 the *dynamic root* of the body. We can not use the dynamic root
3554 of the surround since that root belongs to another thread => stack
3555 is not handled correctly. It may seem ugly to use this extra
3556 layer, but the extra cost in terms of execution time is really
3557 negligible compared to the total amount of time required to create
3558 a thread, and it would reduce maintainability to duplicate the
3559 crucial and complicated steps performed by cwdr.
3561 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3562 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3563 get re-enabled. The important effect of this is that interrupts
3564 are blocked during thread switching so that thread data structures
3565 don't risk getting messed up by an unfortunate signal.
3566 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3567 seems to do more aggressive optimization which actually move
3568 instructions around in these macros in a fatal way. Therefore:
3569 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3570 just superstitious...)
3571 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3572 This macro should be used instead of SCM_ASYNC_TICK since the
3573 latter doesn't do context switches any more.
3575 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3576 instead of SCM_ASYNC_TICK.
3578 * coop.c, iselect.c: Since thread switches are now performed with
3579 interrupts masked, we can't use the old mechanism of delivering
3580 signals immediately when they arrive. Signals must instead be
3581 delivered when the asyncs run *after* the end of the critical
3582 section in scm_internal_select. But this also means after context
3583 switch so that the signal will be delivered to a different thread.
3584 To avoid this, I have changed the protocol of
3585 coop_wait_for_runnable_thread and friends so that they are allowed
3586 to return the original thread. So, if a signal arrives during
3587 scm_internal_select, we won't any longer be forced do a context
3588 switch, but can remain in the same thread and deliver the signal
3591 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3592 scm_asyncs_pending and made it global.
3594 * iselect.c: Small fixes.
3596 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3597 coop_condition_variable_init, coop_condition_variable_wait,
3598 coop_condition_variable_signal): Changed return type from `void'
3599 to `int'. This is to adhere closer to the pthreads interface.
3600 This, in turn, is part of an attempt to provide C versions of the
3601 mutex and condition variable primitives which can be part of a
3602 frontend to COOP or pthreads.
3604 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3605 coop_condition_variable_destroy): New functions.
3607 * coop-threads.c (scm_wait_condition_variable): Use
3608 coop_condition_variable_wait_mutex.
3610 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3611 Definitions moved to coop-defs.h.
3613 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3614 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3615 scm_cond_destroy): New C interface to mutecis and cond vars.
3617 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3619 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3621 * iselect.c: Now several threads can wait on the same file
3622 descriptor. The behaviour is compatible with OS select: All
3623 threads waiting for the fd return with the same status.
3625 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3627 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3628 Can spawn a thread from application C code.
3630 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3632 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3633 gh_doubles2scm): New functions.
3635 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3637 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3638 commented-out version of gh_eval_str()
3640 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3642 * socket.c (scm_bind): free soka after use.
3644 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3646 * stime.c (tzvar): new variable.
3647 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3648 avoid memory leaks when allocating.
3650 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3652 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3655 * gc.c, tags.h: Doc fixes.
3657 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3659 * eval.c (macro-eval!): Removed. This function was a design bug.
3660 It allowed memoized code to leak out to the scheme level. Most
3661 things that you could do with `macro-eval!' can be done with
3664 1997-12-20 Tim Pierce <twp@skepsis.com>
3666 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3667 scm_fgets now depends on ftell(3) to know how many bytes were
3670 1997-12-15 Tim Pierce <twp@skepsis.com>
3672 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3673 dealing with strings.
3675 1997-12-13 Tim Pierce <twp@skepsis.com>
3677 Make %read-line more suitable for implementing read-line efficiently.
3678 * ioext.c (scm_read_line): Strip the terminating newline from a
3679 string, and return a cons of the string and its terminator.
3681 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3682 of the string that is read is stored in this memory location.
3683 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3684 * genio.c, genio.h (scm_do_read_line): Update caller.
3685 * ports.h (scm_ptobfuns): Update typedef.
3686 * fports.c (scm_fptob, scm_pipob): Update struct.
3688 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3690 * filesys.c (set_element): Return file descriptor.
3691 (fill_select_type): Return the highest file descriptor.
3692 (scm_select): Tell select about the highest file descriptor. On
3693 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3694 Therefore the extra overhead for calculating the maximum fd seems
3695 to be more than compensated. Is this correct? In any case,
3696 scm_internal_select will be much faster with this info.
3697 (scm_select, fill_select_type, set_element): Don't accept any kind
3698 of object in the file descriptor list or vector.
3700 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3702 * iselect.c (finalize_fd_sets): Bugfix.
3704 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3706 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3707 when using scm_internal_select (since we might switch to another
3710 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3712 * simpos.c (scm_system): always define: use sysmissing if not
3713 available. Check for HAVE_SYSTEM instead of _Windows (does
3714 Windows lack system or does it have an unusable one?).
3715 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3716 Let the argument be optional: if not supplied, call system(NULL).
3718 * ports.c (scm_close_port): relax the type check from OPPORTP to
3719 PORTP; closing a closed port is allowed.
3721 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3723 * fports.c (scm_fgets): Return if the last char in a chunk is
3724 newline. When fgets returns a string whose length is `size-1', it
3725 is ambiguous whether a whole line was retrieved, so we must check
3726 explicitly whether a line terminator is present.
3728 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3730 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3731 before taking the CDR. (Thanks to Harald Meland.)
3733 * filesys.c (scm_stat): Slightly optimized.
3735 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3737 * ports.c (scm_close_port): Make sure the port is open before
3740 * guile-snarf.in: Pass args through to gcc in a way that preserves
3741 whitespace boundaries. (Thanks to Greg Badros.)
3743 1997-12-02 Tim Pierce <twp@skepsis.com>
3745 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3746 statement. (Thanks to Doug Evans for pointing this out.)
3748 1997-12-01 Tim Pierce <twp@skepsis.com>
3750 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3752 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3754 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3755 errno macro expansion of this field name. (errno is a C
3756 preprocessor macro on some systems.)
3758 1997-11-29 Tim Pierce <twp@skepsis.com>
3760 * iselect.c: Doc fix.
3762 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3764 * init.c (scm_start_stack): Removed initialization of
3765 scm_the_last_stack_var.
3767 * backtrace.h: Declare scm_the_last_stack_var.
3769 * backtrace.c: Define scm_the_last_stack_var.
3771 * root.c (mark_root): Don't mark the_last_stack_var.
3773 * root.h (scm_root_state): Removed the_last_stack_var.
3775 * throw.c: Added #include "fluids.h"
3776 (ss_handler): `the-last-stack' is now a fluid.
3778 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3779 --> the_last_stack_fluid.
3781 * backtrace.c: Added #include "fluids.h"
3782 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3783 (scm_backtrace): `the-last-stack' is now a fluid.
3785 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3786 after scm_init_fluids.
3788 1997-11-28 Tim Pierce <twp@skepsis.com>
3790 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3792 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3793 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3795 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3797 * iselect.c (coop_next_runnable_thread,
3798 coop_wait_for_runnable_thread): Disable interrupts so that no
3799 async is executed before a potential error_revive.
3800 (scm_internal_select): Disable interrupts during the parts of the
3801 code which manipulate the sleep queue and the file descriptors.
3803 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3805 * Makefile.am: Added iselect.c and iselect.h.
3807 * coop.c (coop_qinit): Initialize fields used by
3808 scm_internal_select.
3809 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3810 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3811 replacement in iselect.c.
3812 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3813 coop_join): If GUILE_ISELECT enabled, use
3814 coop_wait_for_runnable_thread instead of
3815 coop_next_runnable_thread.
3816 (usleep, sleep): New replacements for system functions if
3817 GUILE_ISELECT is enabled.
3819 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3821 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3823 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3824 iselect.h. Implement Scheme level `select' using
3825 scm_internal_select. (See NEWS.)
3827 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3829 * init.c: Call scm_init_iselect.
3831 * iselect.h, iselect.c: New files. Implements
3832 scm_internal_select. (See NEWS.)
3834 1997-11-27 Tim Pierce <twp@skepsis.com>
3836 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3837 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3838 and scm_must_free, since ultimately the string returned will be copied
3839 by scm_makfrom0str anyway. Also, read any characters that may have
3840 been pushed onto the port with scm_ungetc.
3841 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3842 * ioext.c (scm_read_line): Free string after Guilifying it.
3843 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
3845 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3847 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3849 * gh.h: Safely wrap prototypes for c++ usage.
3851 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3853 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3854 gh_repl (argc, argv).
3856 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3858 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3859 and to invoke scm_shell().
3860 (gh_launch_pad): took out the loading of boot-9.scm from here,
3861 since it is probably best to let the user control that. In fact,
3862 gh_repl() now invokes scm_shell() which does that.
3864 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3866 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3869 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
3871 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
3872 yesterday's underscore patch. (Thanks to Marius Vollmer for
3875 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
3877 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
3878 DLSYM_ADDS_USCORE is not defined.
3880 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
3882 * gh_data.c (gh_uniform_vector_length):
3883 (gh_uniform_vector_ref): started implementing the uniform types in
3886 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3888 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3889 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3891 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3893 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3894 configure.in was changed).
3896 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3898 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3899 * Makefile.in: Regenerated.
3901 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3903 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3904 OPORT is an `open' port, not an output port.
3906 * filesys.c (scm_close, set_element, get_element, scm_chown,
3907 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
3908 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
3909 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
3910 scm_close_port, scm_port_line, scm_set_port_line_x,
3911 scm_port_column, scm_set_port_column_x, scm_port_filename,
3912 scm_set_port_filename_x, scm_port_mode,
3913 scm_close_all_ports_except, scm_set_current_output_port,
3914 scm_set_current_error_port): Likewise
3915 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3916 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
3918 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
3919 * backtrace.c (display_backtrace_body): Likewise
3920 * fports (scm_setvbuf): Likewise
3921 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
3922 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
3923 scm_getpeername, scm_send, scm_sendto): Likewise
3924 * unif.c (scm_uniform_array_write): Likewise
3926 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
3928 Minor problems with substring-related tag changes.
3929 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
3930 exactly what we want to leave in to detect substrings.
3931 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
3932 * tags.h: Fix diagrams and comments describing the S tag bit;
3933 remove vestigial remarks about the D tag bit.
3934 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
3935 * strings.c: Formatting tweaks.
3937 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
3938 variable first; then SCHEME_LOAD_PATH, with a warning message.
3939 (scm_parse_path): New function.
3940 * script.c: Doc fixes.
3942 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
3944 Readline support, from Daniel Risacher.
3945 * readline.c, readline.h: New files.
3946 * init.c: #include "readline.h".
3947 (scm_boot_guile_1): Call scm_init_readline, if we have it.
3948 * Makefile.am (libguile_la_SOURCES): Include readline.c.
3949 * Makefile.in: Regenerated.
3950 * scmconfig.h.in: Regenerated, after change to ../configure.
3952 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3954 * gh.h: gh_vector_set -> gh_vector_set_x
3956 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3958 * gh_data.c (gh_vector_set_x): changed name to make it consistent
3959 with the ! -> _x mapping when going from Scheme to C.
3961 1997-10-19 Mark Galassi <rosalia@cygnus.com>
3963 * gh.h (gh_reverse):
3971 (gh_assoc): added these gh_ functions implemented as macros.
3973 * gh_predicates.c (gh_null_p):
3974 (gh_string_equal_p): added these two missing predicates.
3976 * gh_list.c (gh_append):
3981 (gh_set_cdr_x): added these routines as I go through and try to
3982 complete the picture R4RS functions that should be mirrored in the
3985 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3987 * tags.h (scm_tc7_substring): Changed the comment and code to
3988 conform with the changes below. Folks! We have suddenly two new
3989 free tc7 codes!!! Jummy, jummy!
3991 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
3993 * Makefile.in: Rebuilt.
3994 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
3996 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
3997 * unif.c (scm_vector_set_length_x): Don't handle multibyte
3999 * tag.c (scm_utag_mb_string, scm_utag_mb_substring): Removed.
4000 (scm_tag): Don't handle multibyte strings.
4001 * read.c: Don't include mbstrings.h.

4011 * eq.c (scm_equal_p): Use SCM_TYP7S, not SCM_TYP7SD.
4012 * tags.h (SCM_TYP7SD): Removed.
4013 (SCM_TYP7D): Removed.
4014 (scm_tc7_mb_string): Removed.
4015 (scm_tc7_mb_substring): Removed.

4018 Don't include "mbstrings.h".
4019 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
4020 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
4022 Don't include "mbstrings.h".
4023 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
4024 (SCM_SYMBOL_SLOTS): Define as 4.
4025 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
4026 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,

4040 (scm_gen_putc, scm_gen_puts, scm_gen_write, scm_get_getc):
4042 (scm_putc, scm_puts, scm_lfwrite): No longer static.
4043 (scm_getc): No longer static; handle line and column changes.
4044 (scm_ungetc): Renamed from scm_gen_ungetc.
4045 (scm_do_read_line): Renamed from scm_gen_read_line.
4046 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
4047 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
4049 1997-10-12 Mark Galassi <rosalia@cygnus.com>
4051 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
4053 * gh_test_c.c (c_vector_test): some improvements on the vector
4056 * gh.h (gh_vector): this used to exist but do the wrong thing.
4057 Now it (almost) does the right thing, though it takes a list
4058 instead of the individual arguments. I need to see how it could
4060 (gh_list_to_vector): added this function as a macro. Corresponds
4061 to Scheme's (list->vector ...).
4062 (gh_vector_to_list): added this function as a macro. Corresponds
4063 to Scheme's (vector->list ...).
4065 * gh_data.c (gh_vector_ref): renamed from gh_vref to
4066 gh_vector_ref, so that it resembles the Scheme routines more.
4067 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
4068 resembles the Scheme routines more.
4069 (gh_make_vector): this used to be (stupidly) called gh_vector().
4070 This is the right name, since it does the same thing as the Scheme
4071 (make-vector ...) procedure.
4073 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4075 * ports.h: #include "libguile/print.h"
4077 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
4078 Some indentation fixes.
4080 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
4081 longer a user field; New field: class_flags.
4083 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
4085 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
4087 * gh_data.c (gh_bool2scm): new function which replaces
4088 gh_int2scmb(), which is now tagged as obsolete.
4090 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4092 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4093 macros should by convention not test for NIMPness.)
4094 (SCM_COERCE_OPORT): Adjust indentation.
4096 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4097 SCM_NIMP test before SCM_PRINT_STATE_P.
4099 * struct.c, struct.h, gc.c: Renamed:
4100 scm_struct_i_layout --> scm_vtable_index_layout
4101 scm_struct_i_vcell --> scm_vtable_index_vcell
4102 scm_struct_i_vtable --> scm_vtable_index_vtable
4103 scm_struct_i_printer --> scm_vtable_index_printer
4104 scm_struct_i_vtable_offset --> scm_vtable_offset_user
4106 * struct.c (scm_print_struct): Use new printer slot; Default
4107 printing: Also output hex code of vtable so that type identity
4108 will be indicated as well.
4109 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4110 Removed struct_printer_var; Removed struct-vtable-offset;
4111 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4112 vtable-offset-user): New constants.
4114 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
4115 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
4116 If this slot contains a procedure, use that to print structures of
4117 the type represented by this vtable.
4119 * print.c (scm_iprin1): Don't print arguments of macro
4120 transformers. (They are always: exp env.); Bugfix: Unmemoize
4121 transformer source with correct environment.
4123 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4125 Streamlining of call-with-dynamic-root:
4127 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
4128 there is now only one catch.
4129 (cwdr_outer_body): Removed.
4130 (cwdr_handler): New function.
4131 (scm_internal_cwdr): New function to perform the function of cwdr
4132 but take args that are more useful to C code. Also, the handler
4133 is now invoked *outside* of the new dynamic root, like the docs
4134 say. We no longer have to catch absolutely all errors, the caller
4135 is responsible for using a handler that does not throw, if he
4137 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4138 * root.h (scm_internal_cwdr): New prototype.
4140 Even more but risky streamlining:
4142 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4143 allocation of the jumpbuf of a root continuation. The changes
4144 below are controlled by it. They are now deactivated.
4145 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4146 the JMPBUF of the scm_rootcont to NULL before returning.
4148 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4149 when they are non-NULL.
4150 (scm_gc_mark): Likewise, mark only when non-NULL.
4152 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4153 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4155 * gc.c (scm_done_malloc): New function.
4156 gc.h (scm_done_malloc): New prototype.
4158 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
4159 (struct scm_print_state) [revealed]: New field.
4160 (scm_print_state_vtable): Make visible to the outside world for
4161 type checking purposes.
4162 (scm_valid_oport_value_p): New prototype.
4164 * print.c (scm_valid_oport_value_p): New function to check whether
4165 a certain value is acceptable as a port argument.
4166 (scm_print_state_vtable): New variable.
4167 (scm_free_print_state): Set `revealed' field to false.
4168 (scm_iprin1): Call user supplied closure printer with
4169 scm_printer_apply. Print in the traditional way when there isn't
4170 one or when it returns #f.
4171 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4172 Accept a port/print-state pair in addition to just a port.
4173 (scm_prin1): Don't return the print_state to the pool when it has
4175 (scm_printer_apply): Set `revealed' field of print_state to true.
4176 (scm_init_print): Set scm_print_state_vtable.
4177 (print_state_fluid, print_state_fluid_num): Removed.
4179 * throw.h (scm_handle_by_proc_catching_all): New prototype
4180 throw.c (scm_handle_by_proc_catching_all): New function
4182 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4184 * Makefile.in: Regenerated with automake 1.2c.
4186 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4188 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4189 was looping endlessly.
4191 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4193 * strports.c (scm_eval_string): Don't close the port.
4195 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4196 former returns a nice normal integer. (Thanks to Daniel
4199 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4201 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4202 makefile variable as a build parameter called LIBS. The
4203 build-guile program will use this, for the time being.
4204 * Makefile.in: Regenerated.
4206 Thanks to Shiro Kawai:
4207 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4208 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4211 * Makefile.in: Regenerated with automake 1.2a.
4213 * script.c (scm_compile_shell_switches): If we hit the -c or --
4214 arguments, don't set the car of (command-line) to scm_usage_name,
4215 the prettified name of the guile executable; give it the full
4216 path, the way shells usually handle $0.
4218 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4220 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4221 Scheme-level name `array-map' and renamed `serial-array-map' to
4222 `serial-array-map!'.
4224 * backtrace.c: Introduced exception handlers which now enclose
4225 `display-error' and `display-backtrace' so that error reporting
4226 won't get into infinite loops if an error occurs during displaying
4227 of the error. This can very easily happen with user supplied
4228 print call-back routines.
4230 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4232 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4233 the names `serial-array-map' and `array-map' should be removed.)
4235 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4237 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4238 Added #include "objects.h"
4240 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4241 Add #include "feature.h".
4243 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4244 (modinclude_HEADERS): Added objects.h.
4246 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4247 This test is needed at many places in the code and should be
4248 abstracted. (Motivated by the need of this test in libguiletk.)
4250 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4251 (scm_eval_string), load.c (scm_primitive_load,
4252 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4253 Use SCM_EOF_OBJECT_P.
4255 * eval.c (scm_init_eval): Add feature `delay'.
4257 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4259 * scmhob.h: Removed.
4261 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4263 * list.h (SCM_LISTn): New macros. Make list creation in C code
4264 prettier. The idea comes from STk.
4266 * sequences.h, sequences.c, append.h, append.c: Removed. These
4267 files implemented non-R4RS operations which would encourage
4268 non-portable programming style and less easy-to-read code.
4270 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4273 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4274 sequences.h, #include append.h.
4276 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4279 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4281 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4283 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4285 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4287 * eval.c: Added #include "objects.h"
4289 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4292 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4293 adjacent smob numbers.
4295 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4297 * procprop.h: Added declaration of scm_i_inner_name.
4299 * gsubr.c: New global symbol scm_i_inner_name.
4301 * debug.c (scm_procedure_name): Try procedure property
4302 `inner-name' if `name' fails.
4304 * print.c (scm_iprin1): Use scm_macro_name.
4306 * eval.c (scm_m_define): Give names to macros as well; Only the
4307 first top-level definition gives a procedure/macro a name.
4308 Otherwise confusing names can turn up in backtraces.
4309 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4310 `name'; Give names to macros as well.
4312 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4313 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4316 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4318 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4320 (prinmacro): Removed. The code has been moved/merged into print.c
4321 in order to decrease code redundancy. We want macros to print in
4322 a way equivalent to procedures, and it would be silly to duplicate
4323 the required code. (We don't want to maintain two places.)
4324 (macrosmob): Print field is now a NULL pointer.
4326 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4327 scm_macro_transformer): New prototypes.
4328 (scm_tc16_macro): Declared.
4330 * print.c (scm_iprin1): Added code for printing of macros. Macros
4331 are now printed in a way equivalent to procedures.
4333 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4335 * procs.h (scm_closure_p): Added declaration.
4337 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4339 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4340 Shouldn't pass "heap" as the subr name.
4342 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4344 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4345 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4346 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4347 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4348 SCM_BOOL_T. Any non-false value is true.
4350 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4352 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4353 scm_gensym): Added prototypes.
4355 * symbols.c (scm_gensym): New function. This will speed up
4356 certain types of applications (such as macro systems) which
4357 generate lots of symbols.
4359 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4361 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4363 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4365 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4366 specifier, since (2) or (2 . 3) would cause SEGV.
4367 (scm_transpose_array): more argument checking fixes.
4369 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4371 * Makefile.in: Regenerated.
4373 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4375 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4377 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4379 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4381 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4383 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4384 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4387 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4388 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4389 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4390 scm_array_p, scm_array_rank, scm_array_dimensions,
4391 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4392 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4393 scm_array_prototype): Added case scm_tc7_wvect.
4395 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4397 * errno.h: prototype for scm_strerror.
4398 * error.c (scm_strerror): new procedure.
4400 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4402 * list.c (scm_list_append_x): Allow non-pair as last argument.
4403 This is consistent with the R4RS append and is probably the
4404 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4406 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4408 * stime.h: prototype for scm_times.
4409 * stime.c (scm_times): new procedure.
4410 * ioext.c (scm_fseek): if the first argument is a file descriptor
4412 (scm_ftell): if the first argument is a file descriptor call lseek
4414 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
4415 * filesys.c (scm_chmod): if the first argument is a file descriptor,
4417 (scm_chown): if the first argument is a port or file descriptor,
4419 (scm_truncate_file): new procedure.
4420 Add DEFER/ALLOW INTS to a few other procedures.
4421 (scm_fsync): new procedure.
4422 (scm_open_fdes): new procedure.
4423 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
4425 (scm_fcntl): the first argument can now be a file descriptor. The
4426 third argument is now optional.
4428 * posix.c (scm_execl, scm_execlp): make the filename argument
4429 compulsory, since omitting it causes SEGV.
4430 (scm_sync): return unspecified instead of #f.
4431 (scm_execle): new procedure.
4432 (environ_list_to_c): new procedure.
4433 (scm_environ): use environ_list_to_c. disable interrupts.
4434 (scm_convert_exec_args): take pos and subr arguments and
4435 improve error checking.
4437 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4439 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4440 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4441 argument to SCM_ASSERT. Furthermore, the name of the function
4442 should be passed as first argument when signalling
4443 SCM_WNA. (Thanks to Thomas Morgan)
4445 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4446 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4447 dispatches on the number of actual args has a default case
4448 reporting an internal error. This is a vestige from a version
4449 that mallocated a SCM vector to hold the arguments. In the
4450 current version this check is too late: if it ever happens we will
4451 have already overstepped the bounds of the array.
4453 Also, the patch [...] adds a check for too many actual arguments."
4455 mdj: Removed check for "internal programming error".
4457 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4459 * gh_io.c (gh_write): New function.
4461 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
4462 throw.c (scm_internal_stack_catch): New sibling to the other catch
4463 functions. Code moved from gh_eval.c.
4464 throw.h: Added header.
4465 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
4466 scm_internal_stack_catch.
4468 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4470 * ioext.h: fix up prototypes.
4471 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
4472 Scheme name is now dup->fdes.
4473 (scm_dup_to_fdes): make the second argument optional and
4474 fold in the functionality of scm_primitive_dup.
4475 (scm_primitive_dup): deleted.
4477 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4479 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
4480 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4481 ultrix are defined. Use setvbuf instead of setbuf.
4482 (scm_setvbuf): new procedure.
4483 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
4484 (scm_setfileno): moved from ioext.c.
4485 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
4486 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
4488 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4490 * fluids.c (scm_fluid_p): New function.
4491 * fluids.h (scm_fluid_p): New prototype.
4493 Sat Jul 26 21:33:37 1997 Marius Vollmer <mvo@zagadka.ping.de>
4495 * print.c (scm_iprin1): Enter printed structures into the print
4496 state as nested data while they are printed.
4497 (print_state_fluid, print_state_fluid_num): New variables.
4498 (scm_init_print): Initialize them.
4499 (scm_iprin): If print_state_fluid carries a print_state, use that
4500 instead of creating a new one.
4501 (scm_printer_apply, apply_stub, struct apply_data): New
4502 definitions to help with calling printer functions written in
4504 * print.h (scm_printer_apply): New prototype.
4506 * struct.c (scm_print_struct): Use scm_printer_apply to call the
4507 user defined struct printer.

4517 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
4518 SCM_ASSERT: arg comes before pos.
4520 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4522 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
4523 to a list of length zero correctly.

4541 * ioext.h: removed scm_duplicate_port prototype.
4543 * ioext.c (scm_primitive_dup2): return the new file descriptor
4544 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
4546 (scm_fdopen): bug fix: don't try to make port unbuffered until its
4547 stream has been set.
4548 (scm_duplicate_port): deleted, there's now an implementation in
4550 (scm_primitive_dup2): do nothing if newfd == oldfd.
4552 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
4554 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

4561 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
4563 * ports.h: prototypes too.
4564 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
4566 * fports.h: prototype too.
4567 * fports.c (scm_evict_ports): moved from ioext.c.
4569 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4571 * ports.c (scm_close_port): return a boolean instead of unspecified.
4572 throw an error if an error other than EBADF occurs.
4574 * filesys.h: scm_close prototype.
4575 * filesys.c (scm_close): new procedure, can close file descriptors
4576 and ports (scsh compatible).
4578 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
4581 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
4583 * fluids.c, fluid.h: New files.
4584 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
4585 (modinclude_HEADERS): Added "fluids.h"

4595 unique for the new root when it has a parent.
4597 * smob.h: Include "libguile/print.h" to make scm_print_state
4600 * dynl.c (free_dynl_obj): New function to free the dynamic object
4601 data. (dynl_smob): Use it.
4602 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4603 the dynamic object data below the linking of the object to avoid
4604 memory leak when the linking code throws an error. Now the code
4605 leaks a whole dynamically linked library when must_malloc throws,
4606 but that should be much less likely.
4608 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4610 Changes to compile under gnu-win32, from Marcus Daniels:
4611 * stime.c (tzset): If tzset isn't provided, make it a NOP.
4612 (scm_localtime): Change SCM_EOF to SCM_EOL.
4613 (scm_mktime): Likewise.
4614 * socket.c: Don't include sys/un.h unless autoconf tells
4615 us Unix domain sockets are available.
4616 (scm_fill_sockaddr): Ignore Unix domain code.
4617 (scm_addr_vector): Likewise.
4618 (scm_init_addr_buffer): Likewise.

4621 * simpos.c (SYSTNAME): Treat cygwin like Unix.
4622 * scmsigs.c (scm_pause): Don't include unless pause was found
4624 * posix.c (scm_getgroups): Don't include unless support function
4625 was found during autoconf (in this case, getgroups).
4626 (scm_setpwent): For setpwent.
4627 (scm_setegid): For setegid.
4628 * net_db.c (scm_inet_netof): Don't include unless support
4629 function was found during autoconf (in this case, inet_netof).
4630 (scm_lnaof): For inet_lnaof.

4643 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
4644 scm_misc_error, not SCM_EOF.
4646 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
4647 arguments for formatting the error message, not SCM_BOOL_F. I
4648 think this is left over from the (eq? '() #f) days.
4650 * read.c (recsexpr): Give this a dummy definition if
4651 DEBUG_EXTENSIONS isn't #defined.
4653 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
4655 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

4665 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
4666 alloca.lo will be included in @LIBLOBJS@. Something better than
4667 this should be possible.
4668 * Makefile.in: Regenerated.
4670 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4672 * simpos.h: prototype for scm_primitive_exit.
4673 * simpos.c (scm_primitive_exit): new procedure, terminates the
4674 process without unwinding the stack.
4676 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
4678 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
4679 argument and logior its components together, so the user doesn't
4680 have to do this explicitly. Also, if regexp/basic is supplied, then
4681 turn off REG_EXTENDED.
4682 (scm_init_regex_posix): New regexp/basic symbol.
4683 (REG_BASIC): #define this if it is not already present.
4685 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4687 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.

4699 * Makefile.in: Regenerated.
4701 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
4702 flag; I don't think we support it.
4703 (scm_make_regexp): Make sure the user doesn't pass the
4706 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4708 (scm_init_regex_posix): Define constants for the REG_mumble flags;
4709 name them according to the SCSH convention: regexp/mumble.
4711 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.

4716 Makefile directory variables. Print a message, but don't print
4718 (versiondat.h): Print a message, but don't print all the commands.
4719 * load.c: #include "alist.h".
4720 (init_build_info): New function.
4721 (scm_init_load): Call it.
4722 * Makefile.in: Regenerated.
4724 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
4726 * root.c: Establish a reliable catch-all handler for the new root.
4727 After all the Scheme handler function might signal an error too,
4728 and we don't want to lose that.
4729 (cwdr_inner_body): Renamed from cwdr_body.
4730 (cwdr_outer_body): New function, to establish the user's handler,
4731 and pass control to cwdr_inner_body.
4732 (cwdr): Establish the reliable catch-all handler here, and pass
4733 control to cwdr_outer_body.
4734 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
4735 the user's handler through to cwdr_outer_body.
4736 * throw.c (scm_handle_by_message): Move guts into....
4737 (handler_message): New static function.
4738 (scm_handle_by_message_noexit): New function.
4739 * throw.h (scm_handle_by_message_noexit): New prototype.
4741 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
4742 across this. Only works on GCC. Otherwise, we hope for the best.
4743 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4744 the feeling that real thread systems will not need this...
4746 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4748 Try to detect when people are using one version of libguile and a
4749 different version of ice-9. People have been skewing things and
4750 sending in bug reports.
4751 * Makefile.am (versiondat.h): New file to generate.
4752 * version.c: #include "versiondat.h", to get version info.
4753 (scm_libguile_config_stamp): New function.

4756 * scmconfig.h.in, Makefile.in: Regenerated.
4757 * Makefile.in: Regenerated.
4759 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
4760 primitive definitions under their Scheme names.
4762 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4763 1:2. Helps avoid confusion between installed and uninstalled libs.
4765 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4768 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4769 backslash from definition; this should be used like: GDB_INTERFACE;
4771 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4773 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
4774 new port unbuffered until its stream has been set.
4776 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4778 * ports.h: new prototype.
4779 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
4781 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
4783 Make things compile neatly under Sun's C compiler.
4784 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
4785 * extchrs.c (xmbtowc): Make the second arg a normal char, not
4786 unsigned, because that's what the ANSI function takes.
4787 * extchrs.h (xmbtowc): Corresponding change to prototype.
4788 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4790 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4791 argument plain char *.
4792 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
4794 * tag.c (scm_tag): Remove unreachable statement.
4795 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4796 top of the word, it should be unsigned.
4798 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4799 is defined, to avoid warnings; it's only used in the
4800 conflict-checking code. Which might go away anyway.
4801 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4802 conditionals; put the label definition in an #if too, to stifle
4805 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4806 ChangeLog-threads in the distribution.
4807 * Makefile.in: Regenerated.
4809 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4811 * guile-snarf.in: Changed regexp to support CPPs that insert
4812 whitespace between lexical tokens (which munges the `%%%' snarf
4815 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4817 * load.c (scm_init_load_path): Append $(datadir)/guile to
4818 %load-path, so modules do not have to be installed in Guile's
4819 current version directory.
4821 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4823 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4824 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4825 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
4826 call the sysdep functions with deferred ints.
4827 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
4828 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
4829 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
4832 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
4835 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
4837 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
4839 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
4841 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
4844 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
4846 * eval.c (scm_lookupcar1): New procedure to cope with a race
4847 condition during lookup (when using threads).
4848 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4849 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4852 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4854 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4855 supplied. (Change from Tim Pierce.)
4857 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4859 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4860 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4861 default and not `()'. `#f' is the canonical non-value in Scheme,
4864 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4866 * struct.c (struct_printer): New variable that holds a handle on
4867 the Scheme variable *struct-printer*. This variable can be set by
4868 Scheme code to override the printing of structures.
4869 (scm_print_struct): If struct_printer is set, call it. If it is
4870 not set, or returns #f, print the structure in the old fashion.
4871 Include "eval.h" for scm_apply.
4873 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4875 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4876 scm_struct_i_n_words to get the number of fields, not
4877 -scm_struct_n_extra_words.
4879 On the route to fancier struct printing:
4880 * struct.c (scm_print_struct): New function to print a structure.
4881 Include "genio.h" to support it. This function doesn't do
4882 anything interesting right now, but I think it should be here
4884 * struct.h: Include "print.h" and add prototype for
4886 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4887 print structures ourself.
4889 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4891 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4892 before applying the handler in case it doesn't return.
4894 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4896 * scmsigs.h, async.h: updated.
4898 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4901 * posix.c (scm_uname): interpret only negative values as an error.
4902 Solaris normally returns a positive value.
4904 * script.c (scm_compile_shell_switches): if we are not going into
4905 an interactive repl, set scm_mask_ints to zero so that asyncs can
4908 * simpos.c (scm_system): don't ignore/unignore signals around
4911 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4914 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4915 done in boot-9.scm instead.
4917 * scmsigs.c, async.c: Major rewriting of signal handling code.
4918 (scm_sigaction): new procedure.
4919 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4921 (scm_raise): return unspecified, throw error on failure.
4923 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4925 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4926 feature, to help boot-9.scm decide whether to import the regex
4929 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4931 * eval.c: Include scmconfig.h at the beginning of the file so that
4932 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
4935 * regex-posix.c: #include "_scm.h" before conditionally #including
4936 <regex.h>; the former defines HAVE_REGCOMP.
4938 * regex-posix.c: #include <regex.h> conditionally, so the file is
4939 CPP'able (for dependency scanning) even on systems that don't have
4942 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4944 Add new R4RS-compliant syntax for keywords.
4945 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
4946 regardless of the setting of the `keywords' read option.
4947 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
4948 can be re-read no matter what the setting of the `keywords' read
4951 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
4953 Add support for POSIX regular expressions.
4955 * regex-posix.c, regex-posix.h: New files. (Some code
4956 is taken liberally from rx/rgx.c in the old Guile dist.)
4958 * init.c: Include regex-posix.h.
4959 (scm_boot_guile_1): Call scm_init_regex_posix.
4961 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
4962 Add regex-posix.[ch] sources.
4963 * Makefile.in: Regenerated.
4965 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
4966 to do this automatically? It didn't for me, bleh.)
4968 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
4970 * fports.c (print_pipe_port): New function.
4971 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
4972 latter doesn't even take the right arguments.
4974 * Makefile.am: Increment shared lib revision number. I think
4975 sometimes the uninstalled Guile finds the installed shared lib;
4976 Gord says doing this might help. As things turned out, I can't
4977 say whether it does.
4978 * Makefile.in: Regenerated.
4980 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
4981 passing it as the closure argument to scm_boot_guile. (Bill
4984 * ports.c (print_void_port, putc_void_port, puts_void_port,
4985 write_void_port, flush_void_port, getc_void_port, close_void_port,
4986 noop0): Use ANSI prototypes instead of K&R declarations, so the
4987 initialization of void_port_ptob gets aggressively type-checked.
4988 Fix arguments of print_void_port and write_void_port. (Bill

5024 * script.c (scm_find_executable): Use prototype-style definition
5025 here; apparently it's not quite right to have const in a prototype
5026 and then use a K&R declaration. I wonder if stuff like this will
5027 go away if we compile with -Wrequire-prototypes, or whatever that
5028 is... (Bernard URBAN)
5030 * scmhob.h: New text from Bernard URBAN.
5032 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5034 * script.c: Don't #define const on hpux. Configure takes care of
5035 this. (Thanks to Larry Schwimmer.)
5037 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5038 decide whether to #include <unistd.h>, instead of listing a bunch
5039 of systems. Don't #include stdio twice. Removed dyked-out
5040 definition of scm_find_impl_file.
5042 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5044 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5045 library version info to 1:0.
5046 * Makefile.in: Regenerated.

5054 significantly in 1997, but only had copyright years for 1996.
5055 Also, change name of copyright holder on some from Mikael
5056 Djurfeldt to Free Software Foundation; he has signed papers
5057 assigning the changes to the FSF.
5059 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5060 reason not to give the user the option.
5062 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5063 Return #f on end-of-file when scanning table (i.e. when called
5064 with no arguments). Try to catch errors, when we can.
5065 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5067 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5068 external declarations. These are useful.
5070 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5072 * posix.c: don't include <sys/select.h> or define macros for
5073 select, since they were not used in this file.
5075 * filesys.c (scm_select): make the fifth parameter microseconds,
5076 not milliseconds. let the fourth parameter be either a real value
5077 or an integer or #f. The first, second and third arguments can
5078 now be vectors: the type of the corresponding return set will be
5080 (set_element, get_element): new static procedures.
5082 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5084 * strports.c (scm_eval_string): New function.
5085 (scm_eval_0str): Trivially re-implemented in terms of
5087 * strports.h (scm_eval_string): New extern decl.
5089 * net_db.c (h_errno): Add extern decl for this.
5091 * fports.c (local_pclose): New function.
5092 (scm_pipob): Use it in the initializer here.
5095 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5096 Use a meaningful error message when signalling an error. For
5097 this, scm_gethost must check h_errno rather than errno.
5099 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5101 * Makefile.in: Regenerated, using automake-1.1p.
5103 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5105 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5106 not SCM_UNSPECIFIED.
5108 * script.c (scm_compile_shell_switches): don't append (quit) if
5110 (scm_shell): call scm_exit_status and exit on the result of the
5113 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5115 Ensure that shared substrings are handled properly when passed to
5116 a system call or other foreign function. Many thanks to Tim
5118 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5119 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5120 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5121 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

5123 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5124 (scm_display_error_message): use RO macros when strings may be RO.
5125 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5126 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5127 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

5131 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
5132 scm_strftime), vports.c (scm_make_soft_port): use
5133 SCM_COERCE_SUBSTR to make sure shared substrings are
5136 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5138 * error.c (scm_error): Add newline to error message.
5140 * init.c (scm_init_standard_ports): Doc fix.
5142 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5144 * dynl-shl.c: Completely replaced with new code from Bernard
5147 * script.c (scm_ice_9_already_loaded): New variable.
5148 (scm_compile_shell_switches): Use it.
5150 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5152 * filesys.c (scm_input_waiting_p): add missing third argument to
5155 * stime.c (scm_localtime): copy the result of localtime before
5156 calling gmtime in case they share a buffer.
5157 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5160 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5162 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5164 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5166 * Makefile.am (check-local): New target, which causes 'make check'
5167 to run gh_test_c and gh_test_repl, with some trivial input.
5168 * Makefile.in: Rgnrtd.
5170 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5172 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5175 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5177 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5178 sure how this was supposed to work.
5179 (scm_async_click): don't send SCM_TICK_SIGNAL.
5180 (scm_init_async): don't initialize %tick-thunk.
5182 * the following change doesn't affect the Scheme interface:
5183 gc-thunk is called at the end of garbage collection. however it's
5184 no longer implemented by pretending it's a signal.
5186 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5187 system async corresponding to scm_gc_thunk.
5188 * async.h: declare scm_gc_async.
5189 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5190 gc-thunk directly, instead of going through a signal handler.
5191 (scm_gc_async): new variable, points to the GC system-async.
5192 (scm_init_async): save the GC async as scm_gc_async instead
5193 of using system_signal_asyncs.
5194 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5196 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
5198 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
5199 Don't screw up if we're interrupted.
5200 * Makefile.in: Regeneradet.
5202 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5204 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5206 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5207 we're not using AM_INIT_GUILE_MODULE any more.
5208 * Makefile.in: Reneregated.
5210 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5212 Functions for finding variable bindings, grace à Tim Pierce.
5213 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5214 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5216 Get 'make dist' to work again.
5217 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5218 * Makefile.in: Regenerated, like a surry without a fringe on top.
5220 Changes for reduced Guile distribution: one configure script,
5222 * configure.in, configure: Removed.
5223 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5224 real configure script lives.
5225 * Makefile.in, scmconfig.h.in: Regenerated.
5227 * init.c: #include "script.h", to get prototype for script.c's
5230 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5232 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5233 scm_must_malloc, not raw malloc.
5235 * script.c (scm_compile_shell_switches): Dyke out debugging output
5238 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5240 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5242 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5243 system has them. Hope this is safe. Previously
5244 sys/timeb.h was included if HAVE_FTIME was defined or if
5245 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5246 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5248 * ioext.c (scm_setfileno): add missing third argument to
5249 scm_misc_error call.
5251 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5253 * eq.c (scm_equal_p): Correctly compare strings of different
5254 varieties. (Thanks to Tim Pierce.)
5256 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5258 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5259 #! block comment must occur on a line all by itself.
5261 Move most of the guts of shell command processing into libguile,
5262 so guile.c can be very small (and eventuallly auto-generated. (I
5263 mean, generated mechanically, not self-generated. Hmm.))
5264 * guile.c, script.c, script.h: New source files.
5265 * init.c (scm_boot_guile_1): Call scm_init_script.
5266 * libguile.h: #include "script.h".
5267 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5268 targets, for new executable.
5269 (libguile_la_SOURCES): Mention script.c.
5270 (modinclude_HEADERS): Add script.h.
5271 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5272 not dynamic linking is enabled. This is because we're generating
5273 executables now. Move CY_AC_WITH_THREADS call after those, so the
5274 values of cy_cv_threads_libs captures the libs chosen above.
5275 * Makefile.in, configure, aclocal.m4: Regenerated.
5277 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5278 We don't maintain this interface any more, and it just confuses
5281 * alloca.c: #include <scmconfig.h>, not <config.h>.
5282 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5283 it'll get included in disties.
5285 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5287 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5288 be distributed, because they confuse people.
5289 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5291 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5293 * configure.in: check for presence of gethostent (not present on
5294 OpenBSD by default).
5295 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5296 * configure, scmconfig.h.in: Regenerated.
5298 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5300 * backtrace.c (scm_backtrace): Split message string across
5301 newlines properly. GCC is more tolerant of this than other
5304 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5306 Merge threads directory into libguile.
5307 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5308 threads.h: New source files.
5309 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
5310 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5312 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5313 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5314 coop-threads.c.cygnus, coop-threads.h.cygnus.
5315 * configure.in: If we're using threads, include threads.o in
5317 * _scm.h, libguile.h: threads.h lives in this directory now.
5318 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5319 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5320 currently used, but brought along for information's sake.
5321 * ChangeLog-threads: log from old 'threads' directory.
5322 * Makefile.in, configure: Rebuilt.
5324 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5326 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5329 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5331 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5333 Merge GH interface library into libguile.
5334 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5335 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5336 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5337 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5339 (EXTRA_libguile_la_SOURCES): ... here.
5340 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5341 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5342 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5343 New variables, describing how to build the gh test programs.
5344 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5345 build the test programs, and we probably should have been linking
5346 libguile.la against them all along, to support AIX shared libs.
5347 Add cflags for threads to CFLAGS; add libs for threads to new
5348 variable THREAD_LIBS, used in Makefile.am.
5349 * ChangeLog-gh: log from old `gh' subdirectory.
5350 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5352 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5354 * acconfig.h: Undo change of Apr 9; including the definition of
5355 PACKAGE in the guile headers conflicts with applications' own
5357 * scmconfig.h.in: Regenerated.
5359 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
5361 * filesys.c (scm_fcntl): New function from Roland McGrath.
5362 (scm_init_filesys): New symbols for use with fcntl.
5363 * filesys.h: Added prototype.
5365 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
5366 when PROC is receiving no arguments.
5368 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5370 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5371 have S_IFSOCK. This is the case under Ultrix.
5373 * posix.c (scm_status_exit_val, scm_status_exit_val,
5374 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5375 Ultrix versions of WIFSTOPPED, etc., which assume that their
5376 arguments are lvalues (hmm).
5378 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5380 * eval.c: Doc fixes.
5382 * throw.c: Doc fixes; rearranged.
5384 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5386 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5388 * acconfig.h: Added entry for PACKAGE.
5389 * scmconfig.h.in: Regenerated.
5391 Changes to work with automake-1.1n, which has better libtool support.
5392 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5393 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5395 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5397 * Makefile.in: Rebuild.
5399 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5401 * stime.c (scm_mktime): take an optional zone argument.
5402 (scm_localtime): check putenv return value.
5403 (scm_strftime, scm_strptime): moved from posix.c. move #include
5405 stime.h, posix.h: update prototypes.
5406 (bdtime2c, setzone, restorezone): new static procedures.
5407 (scm_mktime, scm_strftime): use them.
5408 (scm_strftime): don't call mktime before strftime. Use
5409 filltime for return value.
5410 (filltime): convert NULL zname to #f.
5411 (scm_strptime): return a count of characters consumed, not
5412 the remaining string.
5414 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5416 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
5417 (scm_mktime): likewise.
5419 Uncomment localtime and mktime.
5421 * configure.in: add AC_STRUCT_TIMEZONE.
5423 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5425 * stime.c (scm_init_stime): don't define ticks/sec.
5426 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5427 return value problem and is still portable.)
5429 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5431 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5432 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5433 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5434 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5435 cpp_err_symbols.c): Corresponding changes.
5436 * Makefile.in: Regenerated.
5438 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5440 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5441 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5442 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5443 * putenv.c: new file, from sh-utils 1.12.
5445 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5446 since allocation isn't for Scheme objects.
5447 (scm_putenv): copy strings before placing in the environment.
5449 * stime.c (scm_current_time): throw an error if time returns -1,
5450 instead of returning #f.
5451 (scm_get_internal_real_time, scm_get_internal_real_time): use
5452 scm_long2num for return value instead of SCM_MAKINUM.
5454 * stime.h: prototypes updated.
5456 * stime.c (scm_time_in_msec): apparently unused, deleted.
5458 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5460 * configure.in: check for gettimeofday.
5462 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5463 which may be more usefully portable than a gettimeofday interface.
5465 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5467 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5469 * Makefile.in: Regenerated.
5471 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5473 * stime.c (filltime): recovered static procedure.
5474 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5477 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5478 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5480 * posix.c (scm_mknod): split the mode argument into type and perms
5481 arguments, like the extra fields returned by stat.
5483 * fports.c (scm_pipob): set the close, free and print procedures.
5484 (scm_close_pipe): new procedure.
5486 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5487 define them in boot-9.scm
5489 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5491 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5492 wan't defined. Don't include fd.h.
5494 * Previously fd.h was regenerated whenever configure was run,
5495 forcing a couple of files to be recompiled.
5497 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5498 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5499 Check for _fileno as well as _file.
5501 * ioext.c: don't fd.h.
5502 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5505 * Change the stratigy for getting information about errno
5506 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5507 generating lists of symbols during the build process, which will
5508 not always work, include comprehensive lists in the distribution.
5509 To help keep the lists up to date, the "check_signals" and
5510 "check_errnos" make targets can be used.
5512 * configure.in: don't check for a command to extract errno codes.
5513 * Makefile.am: update file lists, remove errnos.list and errnos.c
5514 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5515 check_errnos targets.
5516 (CLEANFILES): remove errnos.c and errnos.list, add
5517 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5518 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5519 * errnos.default: deleted.
5520 * cpp_signal.c: new file.
5521 * cpp_errno.c: renamed from errnos_get.c.
5522 * cpp_err_symbols, cpp_sig_symbols: new files.
5523 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5524 * error.c (scm_init_error): #include cpp_err_symbols instead of
5526 * posix.c (scm_init_posix): don't intern signal symbols. #include
5529 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5531 * strop.c (scm_i_index): allow the lower bound to be equal to the
5532 length of the string, so a null string doesn't always give an error.
5534 * posix.h: new prototypes.
5535 * posix.c (scm_status_exit_val, scm_status_term_sig,
5536 scm_status_stop_sig): new functions, as in scsh. They break down
5537 process status values as returned by waitpid.
5539 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5541 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5542 configure doesn't know about it.
5544 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5546 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5548 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5549 which defines C variables with global linkage.
5551 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5553 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5556 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5558 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5559 has time to check why this doesn't work well with continuations.
5561 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5563 * Fix shell syntax error; some shells won't tolerate
5564 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5566 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5568 * posix.c (scm_uname): throw an error if uname fails instead
5571 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5573 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5576 * async.c (scm_ints_disabled): definition moved from error.c.
5578 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5580 * acconfig.h: Removed PACKAGE.
5582 * scmconfig.h.in: Regenerated.
5584 * snarf.h: g++ says it's non-portable not to specify the first
5585 argument in a varargs declaration. I introduced the first
5586 argument by using preprocessor conditionals.
5588 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5590 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5591 (scm_freopen): use RO string macros for filename and modes.
5592 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5594 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5595 (scm_mknod): use RO string macros for path.
5597 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5598 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5600 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5601 use SCM_ROSTRINGP and SCM_ROCHARS.
5603 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5605 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5608 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5609 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5610 support for byte vectors.
5612 * print.c (scm_iprin1): Limit number of vector elements printed
5613 according to pstate->length.
5615 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5617 * backtrace.c (scm_display_error_message): don't segv if message
5620 * error.h: prototype for scm_error_scm.
5622 * error.c (scm_error_scm): new procedure, reimplements scm-error
5623 in C and uses scm_error.
5625 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5627 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5628 pointer to the Scheme variable read-hash-procedures and intern it
5629 in scm_init_read. Modify scm_read_hash_extend and
5630 scm_get_hash_procedure to use the pointer.
5632 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5634 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5635 (SCM_KEYWORD_STYLE): defined.
5637 * read.c (scm_read_opts): add a keywords option. This isn't a
5638 boolean option, in case someone wants to add support for DSSSL
5640 Setup scm_keyword_prefix symbol.
5641 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5643 I've left keyword support disabled by default, since it doesn't
5644 seem to break the module system and it gives R4RS standard behaviour.
5645 It can be reactivated with (read-set! keywords 'prefix).
5647 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5649 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5650 before constructing arbiter.
5652 * eval.c (scm_m_define): Bugfix: Check that the object is a
5653 closure before setting the procedure property!
5655 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5657 * ports.c: Removed `ungetc-char-ready?'.
5659 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5661 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5662 (idea from Mikael: make it a pair so scm_permanent object only
5664 (scm_read_hash_extend): don't call scm_permanent_object.
5665 (ideas from Mikael): if chr is already in the list, replace its
5666 procedure instead of appending it again. If proc is #f, remove
5668 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5670 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5672 * gdbint.c (gdb_read): update scm_lreadr usage.
5674 * load.h: update prototypes.
5676 * load.c (scm_primitive_load, scm_read_and_eval_x,
5677 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5679 * read.h: add prototype for scm_read_hash_extend. Change args for
5682 * read.c (scm_read_hash_procedures): new variable.
5683 (scm_read_hash_extend): new procedure.
5684 (scm_get_hash_procedure): new procedure.
5685 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5686 for extended # processing.
5687 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5688 scm_read_token): remove case_i, sharp arguments. Change callers.
5690 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5692 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5693 (SCM_CASE_INSENSITIVE_P): define.
5695 * read.c: add case-insensitive option to scm_read_opts.
5696 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5697 to determine whether to convert symbol case.
5698 (default_case_i): definition removed.
5699 * read.c (scm_read_token): if case_i, downcase ic before doing
5702 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5704 * configure.in: Added configuration option `guile-debug'.
5705 Configure with --enable-guile-debug if you want a bunch of extra
5706 functions used for debugging when developing Guile.
5708 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5710 * procs.c (make-cclo): New undocumented debugging procedure: Make
5711 compiled closure with internal procedure PROC and length LENGTH.
5712 Only compiled if GUILE_DEBUG is defined.
5714 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5716 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5718 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5720 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5721 with 3 or more args internally to the evaluator.
5723 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5725 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5726 with 3 or more args internally to the evaluator. This is mainly
5727 because we don't want to pass entry and exit points of the
5728 debug support twice, but it also seems to increase the speed of
5729 the evaluator for such calls (e. g. (+ 1 2 3)).
5731 * backtrace.c (scm_display_application): New procedure:
5732 display-application; Set fancy printing parameters individually
5733 for different types of display (backtrace, error, application).
5734 (These should of course be customizable!)
5736 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5737 clear the CHECK-flags.
5739 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5741 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5743 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5745 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5746 from pairs with a GLOC in the car.
5748 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5749 otherwise `symbol-hash' will behave badly.
5750 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5751 we get segmentation fault!
5753 * symbols.c: Added #include "weaks.h". New functions:
5754 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5755 moved to an extraneous library when we split libguile.)
5757 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5759 * filesys.c (scm_stat): stat now takes fport arguments too as
5760 documented in the manual.
5762 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5764 * debug.c (scm_single_step): Bugfix: Call continuation with
5765 scm_call_continuation instead of throwing to it.
5767 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5769 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5770 argument wasn't declared to be optional.
5772 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5774 * stime.c (scm_init_stime): Add feature "current-time".
5776 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5778 * throw.h: prototype for scm_exit_status.
5779 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5780 args to derive an exit status. Allows (quit) to work from a
5782 (scm_exit_status): new function.
5785 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5787 * eval.c (scm_deval): Removed some old code.
5788 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5790 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5793 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5796 * procs.c: Introduce the existent C function scm_thunk_p at the
5797 Scheme level as well.
5799 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5801 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5802 used from C to easily lookup the value of a symbol in the current
5805 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5807 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5808 scm_init_unif in this file. This will also fix a previous problem
5811 * configure.in: Added AM_MAINTAINER_MODE
5813 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5815 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5818 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5820 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5821 source files that are not always included in libguile but should
5822 have their dependencies calculated by automake. This variable is
5823 recognized by automake, no further magic is needed.
5824 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5825 to deal exclusively with *.lo files, as it seems. The *.o files
5826 are built automatically when the corresponding *.lo file gets
5829 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5831 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5834 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5836 * unif.c (scm_array_set_x): minor change to argument error checking.
5838 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5840 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5841 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5842 They should only be included in the library at configure.in's
5844 (libguile_la_LDADD): Include the appropriate .lo files here.
5845 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5846 so we know when to build them (and their .lo bretheren).
5847 * configure.in (LIBLOBJS): New substituted variable. We let
5848 configure decide which .o files to include in LIBOBJS, and then
5849 put the corresponding list of .lo files in LIBLOBJS. The latter
5850 is what we pass to libtool.
5851 * Makefile.in, configure: regenerated.
5853 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5855 * symbols.c (scm_sysintern0): New function. Contains the core of
5856 old scm_sysintern but doesn't take a second value argument.
5857 (scm_sysintern): Now uses scm_sysintern0.
5858 (scm_sysintern_no_module_lookup): Renamed to
5859 scm_sysintern0_no_module_lookup and doesn't take a second value
5860 argument any longer.
5862 * symbols.h (scm_sysintern0: Added declaration.
5864 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5865 scm_sysintern when interning option keys. Otherwise we risk
5866 destroying the values of already interned variables.
5868 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5869 scheme-level boolean (use SCM_NFALSEP).
5871 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5873 (scm_backtrace): New function. (C version of old function from
5874 boot-9.scm) Motivation: Make it possible to display backtraces
5875 without depending on boot-9.scm. (I'm uncertain if this
5876 motivation is good enough...)
5878 * root.h (scm_root_state): Add member the_last_stack_var.
5879 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5881 * root.c (mark_root): Mark scm_the_last_stack_var.
5883 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5886 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5888 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5889 1. mark_lazy_catch didn't mark the smob.
5890 2. Both functions above have standard variants:
5891 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5892 free_lazy_catch --> scm_free0.
5894 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5896 * throw.c (scm_internal_lazy_catch): New function.
5897 (scm_lazy_catch): Rewritten to use it.
5898 (scm_ithrow): Handle the new lazy catch representation.
5899 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5900 that doesn't have a jmpbuf is a lazy catch clause.
5901 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5902 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5903 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5905 (scm_init_throw): Register the new lazy-catch smob type.
5906 * throw.h (scm_internal_lazy_catch): decl for new function.
5908 * throw.c (scm_internal_catch): Doc fixes.
5910 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5911 configure.in. Including this might cause problems if applications
5912 that link against libguile include their own copies of alloca, but
5913 if they're using autoconf, they should be adding libguile to LIBS
5914 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5915 the copy in libguile, and things will be okay. (I think.)
5917 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5919 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5921 strop.h: move prototypes too.
5923 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5925 * posix.c (scm_init_posix): don't intern EINTR since it's now done
5928 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
5929 etc. I deleted them from filesys.c long ago, but didn't
5930 notice they were here too (although ineffective since
5931 sys/stat.h wasn't included).
5933 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
5935 * eval.c: Don't define alloca in GCC case. gcc will automatically
5936 use __builtin_alloca if appropriate.
5938 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5940 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
5941 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
5942 that values of automatic variables are preserved. See comments
5943 for safe_setjmp for details.
5945 Change from Thomas Morgan:
5946 * variable.c: Include eq.h.
5947 (var_equal): New function.
5948 (variable_smob): Use var_equal as the discriminator for variables.
5950 * throw.c (s_throw): Remove extraneous declaration.
5952 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
5953 * eval.c: Add necessary CPP cruft to support that.
5954 * configure, Makefile.in, scmconfig.h.in: regenerated.
5956 Change from Thomas Morgan:
5957 * procprop.c (scm_procedure_properties): Convert the Scheme
5958 boolean returned by scm_procedure_p into a C boolean before using
5959 it as a condition for SCM_ASSERT.
5960 (scm_procedure_property): Likewise.
5962 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
5963 indications of Unixness.
5966 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5968 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
5970 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5972 * read.c (scm_lreadr): use scm_misc_error to improve one of the
5973 "unknown # object" error messages.
5975 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
5976 (scm_i_index) and declare it static. Add a 'direction' argument
5977 to indicate what way the search should go.
5978 (scm_i_index): throw out-of-range error instead of wrong-type-arg
5980 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
5981 strop.h: remove scm_i_index, scm_i_rindex prototypes.
5983 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5985 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
5987 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
5988 to avoid clash with various scsh forks.
5990 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
5992 The following two changes (ramap.c, throw.c) are motivated by the
5993 apparent unportability of forward declarations of static arrays of
5994 the form `static foo bar[];'.
5996 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
5997 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
5999 * throw.c (scm_throw): Moved above scm_ithrow.
6001 * options.h: Removed the extern declarations of scm_yes_sym and
6002 scm_no_sym since these are static.
6004 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6006 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6008 * Makefile.am: remove AWK=@AWK@.
6009 Add a rule for generating errnos.list.
6010 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6012 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6013 don't extract errnos, just set a variable (avoids the
6014 need to recompile error.c just because configure is run.)
6016 * unif.h: update prototypes.
6017 * unif.c (scm_uniform_array_read,write): change the offset and
6018 length arguments to start and end, for consistency.
6020 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6022 * ioext.h: update prototypes.
6023 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6024 scm_read_line_x, it's a more general procedure using an
6025 interface from scsh. read-line and read-line! are now defined
6027 Note that the new read-line trims the terminator
6028 by default, previously it was appended to the returned string. An
6029 optional argument specifies how to process the terminator (scsh
6030 compatible). For the old behaviour: (read-line port 'concat).
6031 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6032 returns a pair, but is converted to multiple values if the scsh
6035 socket.h: update prototypes.
6036 * socket.c (scm_recvfrom): for consistency with other procedures,
6037 take start and end as separate optional arguments.
6038 (scm_recv, scm_recvfrom): don't allow the second argument
6039 to be a size, only a buffer. Change the scheme names to
6040 recv! and recvfrom!. Don't return the buffer.
6042 * ioext.h, posix.h: move prototypes too.
6043 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6044 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6045 "read.h" and "unif.h".
6046 * ioext.c: include "chars.h"
6048 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6050 * dynl.c: The dynamic linking and module registration functions
6051 are now defined even when dynamic linking is not available for the
6052 host system. Some of their functionality can be done without
6053 dynamic linking; when it's really needed, they throw errors.
6055 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6057 * configure.in: Only define DYNAMIC_LINKING when one of the system
6058 dependent functions is detected.
6059 * dynl.c (scm_dynamic_func): New function to get the address of a
6060 function in a dynamic object.
6061 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6062 produced by scm_dynamic_func as the thing to call.
6064 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6066 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6067 (scm_register_module_xxx, scm_registered_modules,
6068 scm_clear_registered_modules): New functions.
6070 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6072 * symbols.c (scm_sysintern): Renamed to
6073 scm_sysintern_no_module_lookup.
6074 (scm_sysintern): New function to take the place of the old
6075 scm_sysintern. It uses the current toplevel lookup closure to give
6076 the symbol its value. This is a temporary hack to put packages
6077 like gtcltk into their own module.
6078 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6079 us whether `scm_top_level_lookup_closure_var' has been initialized
6081 * eval.c (scm_init_eval): Set it.
6083 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6085 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6086 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6088 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6090 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6091 scm_sys_dup): deleted: FD capability will be added to other
6093 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6094 scm_fd_free, fd_smob, scm_intern_fd.
6095 (scm_open): renamed from scm_sys_open. Return a port instead of
6096 an FD object. Make the mode argument optional.
6097 (scm_sys_create): deleted, it's just a special case of open.
6098 (scm_init_filesys): move interning of constants O_CREAT etc.,
6099 here (were previously using SCM_CONST_LONG macro).
6100 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6102 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6103 include "fports.h" and <stdio.h>
6104 (scm_stat, scm_select): don't support FD objects.
6106 * error.h: adjust scm_syserror_msg prototype.
6107 * error.c (scm_syserror_msg): take an extra argument for errno.
6108 Using the global value didn't always work, since it could be
6109 reset by procedure calls in the message or args arguments.
6111 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6112 I don't understand why the check was there (and what about the
6115 * strop.c (scm_string_copy): allow shared substrings to be copied.
6117 * unif.h: corresponding change to prototypes.
6118 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6119 recognize two new optional arguments: offset and length. Allow
6120 the port argument to be an integer (file descriptor, for scsh).
6121 Include <unistd.h> for "read" prototype.
6123 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6125 * socket.c: don't include filesys.h.
6127 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6129 * Makefile.am: add AWK=@AWK@ (?)
6131 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6133 Add a rule to generate errnos.c from errnos.
6134 * error.c (scm_init_error): include errnos.c.
6135 * errnos_cnvt.awk: new file, converts the list of errno codes to
6137 * errnos_get.c: new file.
6138 * errnos.default: new file, contains errnos to try if they can't
6139 be extracted from errno.h.
6140 * configure.in: if using GCC, try and extract errno codes from
6144 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6146 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6147 * Makefile.am: Made libguile into a libtool library.
6148 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6149 Set libtool_libs to indicate that libguile is a libtool library.
6150 See guile/ChangeLog for details.
6151 * .cvsignore: ignore "*.lo", the libtool library objects.
6153 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6155 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6156 use htons in getservbyport argument.
6158 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6160 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6161 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6164 * objprop.c (scm_object_property): No need to take the CDR of the
6165 value returned by scm_object_properties, since Aug 20 change.
6167 * configure.in: When checking for struct linger, #include
6168 <sys/types.h> as well as <sys/socket.h>. I've never known
6169 <sys/types.h> to cause any portability problems, and Solaris's
6170 <sys/socket.h> needs it.
6171 * configure: Rebuilt.
6173 I think the Sun compiler has chosen a perverse way to interpret
6174 ANSI declarations combined with K&R definitions. We'll
6175 appease it a little bit. But when it invades France, we fight.
6176 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6177 * print.h (scm_iprlist): Here too.
6178 * numbers.c (scm_divbigdig): Change definition to match
6179 declaration in numbers.h.
6180 * unif.c (scm_makflo): Change definition to match declaration in
6183 * init.c (scm_boot_guile): Don't return the value of
6184 scm_boot_guile_1. This function doesn't return a value;
6185 scm_boot_guile_1 doesn't return a value (or return at all).
6187 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6190 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6191 compile. I have a feeling this function is a bad idea anyway ---
6192 one should always test for features, not systems.
6194 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6195 semicolons. Only pure luck kept this from being noticed earlier.
6197 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6199 * socket.c (scm_recvfrom): Added missing semicolon.
6201 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6203 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6204 the buffer and start and end positions for scsh networking
6207 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6209 * configure.in: Revert previous change to this file; the problem
6210 is due to transient automake weirdness.
6211 * configure: Rebuilt.
6213 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6214 PLUGIN/guile.libs. configure generates the latter from the former.
6215 * Makefile.in: Rebuilt.
6217 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6218 need this if we install scripts, like guile-snarf.
6219 * configure: Rebuilt.
6221 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6223 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6225 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6227 * socket.c (scm_addr_vector): fix faulty scm_listify.
6229 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6231 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6232 style block comment is no longer considered an error.
6234 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6236 * PLUGIN/guile.libs.in: New file.
6237 * PLUGIN/guile.libs: Removed from repository.
6238 * configure.in: Create PLUGIN/guile.libs from
6239 PLUGIN/guile.libs.in. This is for including additonal libraries
6240 needed for dynamic linking.
6241 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6242 instead of PLUGIN/guile.libs.
6244 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6246 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6248 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6249 occurrences of the given element from the list, not just the
6250 first. This is how the Emacs Lisp functions behave, how the
6251 analogous Common Lisp functions behave, and (I believe) how the
6252 older Maclisp functions worked. I realize that this change may
6253 break code, but it seemed better to break it before the Guile
6256 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6257 Their prototypes were already present in gc.h, but they weren't
6259 (scm_init_storage): Initialize scm_protects.
6260 * root.c (scm_protects): New element of scm_sys_protects.
6262 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6264 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6266 * libguile.h: Added #include "libguile/net_db.h".
6268 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6269 30 change. That file is only meant for communication between the
6270 configuration process and load.c. If code linked against libguile
6271 wants to get at the paths mentioned in libpath.h, it can call
6272 functions declared in load.h.
6274 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6276 * libguile.h: Removed #include "libguile/fdsocket.h"
6278 * net_db.c: Added #include <sys/socket.h>.
6280 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6282 * filesys.c (scm_input_waiting_p): use select in preference to
6283 FIONREAD, since the latter doesn't detect EOF.
6284 Throw error if neither select nor FIONREAD available.
6286 * socket.c (scm_connect): take a port, not a fd object.
6287 (scm_fill_sockaddr): throw an error if fam is not recognised.
6288 (scm_bind): use scm_fill_sockaddr.
6289 (scm_listen): take a port, not a fd object.
6290 (scm_accept): take and return a port. return #f in the car if
6291 address can't be got
6292 (scm_sock_fd_to_port): new procedure.
6293 (scm_socket): use scm_sock_fd_to_port.
6294 (scm_addr_vector): throw error if unrecognised address type.
6295 take an extra argument with the calling procedure name.
6296 (scm_getsockname): take a port. return #f if address can't be got.
6297 (scm_getpeername): take a port. return #f if address can't be got.
6298 (scm_recvfrom): take a port. return #f for address component if can't
6300 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6301 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6303 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6305 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6306 use separate data pointers, to allow them to be designed
6307 independently and reused.
6308 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6309 Renamed from catch_body, catch_handler, and uncaught_throw; made
6311 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6313 (scm_catch): Use the above.
6314 (scm_throw): Don't bother printing a message for an uncaught
6315 throw; we establish a default handler in init.
6316 * throw.h (scm_internal_catch): Prototype updated.
6317 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6319 (struct scm_body_thunk_data): New structure, used as data
6320 argument to scm_body_thunk.
6321 * init.c (struct main_func_closure): New structure, packaging up
6322 the data to pass to the user's main function.
6323 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6324 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6325 scm_internal_catch to establish a catch-all handler, using
6326 scm_handle_by_message. This replaces the special-case code in
6328 (invoke_main_func): Body function for scm_internal_catch; invoke
6329 the user's main function, using the main_func_closure pointer to
6330 decide what to pass it.
6331 * root.c (struct cwdr_body_data): Remove handler_proc member.
6332 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6333 (cwdr_handler): Removed.
6335 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6337 * socket.h (SCM_P): update bind prototype.
6338 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6339 include "feature.h".
6340 (scm_socket): return a port, not a file descriptor object.
6341 include "fports.h" and <unistd.h>
6342 (scm_bind): take a port, not a file descriptor object.
6343 take an extra argument for address args.
6345 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6346 INADDR_NONE, INADDR_LOOPBACK.
6348 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6350 * init.c: include net_db.h and not fdsocket.h.
6351 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6353 * Makefile.am: corresponding changes.
6354 * socket.h: renamed from fdsocket.h, fix names.
6355 * net_db.h: renamed from socket.h, fix names.
6356 * socket.c: renamed from fdsocket.c.
6357 remove _sys from procedure names.
6358 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6359 add "socket" to features list.
6360 * net_db.c: renamed from socket.c.
6361 remove _sys from procedure names.
6362 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6363 add "net-db" to features list.
6364 include "net_db.h". don't include <sys/socket.h> or
6367 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6369 * tags.h (scm_tags): Removed comma at end of last enumerator.
6371 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6373 Don't use GCC extensions to allocate space for debugging frames.
6374 (Here he goes again! Why do we put up with this?!)
6375 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6376 an scm_debug_info structure, not an in-line array of them. Add
6377 'info' member, to say how many vect elements we've used, for eval
6379 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6380 a new variable debug_info_end to mark the end of vect, instead of
6381 the address of the 'info' pointer itself.
6382 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6383 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6384 (SCM_APPLY): Explicitly allocate space for debug.vect.
6385 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6386 * stacks.c: Adjusted for new debug frame structure.
6387 (RELOC_INFO, RELOC_FRAME): New macros.
6388 (stack_depth, read_frames): Use them, and new scm_debug_frame
6389 element 'info', instead of magically knowing that eval frames have
6390 an info pointer sitting after vect.
6391 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6393 (scm_init_stacks): Formatting tweaks.
6395 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6397 Give GCC more control flow information, so it can be sure that
6398 variables aren't used uninitialized.
6399 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6400 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6401 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6402 scm_misc_error): Tell GCC that these functions never return.
6403 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6404 out the field type, call abort if SCM_ASSERT returns, to placate
6406 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6407 scm_wta ever returns. We can't handle this case anyway, and this
6408 gives the optimizer more information.
6409 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6410 scm_wta ever returns.
6412 In some cases, the code is fine, but GCC isn't smart enough to
6413 figure that out; this usually happens when one variable is only
6414 initialized and used when a particular condition holds true, and
6415 we know that condition will never change within a given invocation
6416 of the function. In this case, we simply initialize the variables
6417 to placate the compiler, hopefully to a value which will cause a
6418 crash if it is ever actually used.
6419 * print.c (scm_iprin1): Initialize mw_pos.
6420 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6421 * throw.c (scm_ithrow): Initialize dynpair.
6422 * unif.c (scm_uniform_vector_ref): Initialize cra.
6423 * struct.c (init_struct): Initialize prot.
6424 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6426 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6427 if EXPR contains no expressions.
6429 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6431 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6432 cause an infinite loop (???). So much for the algebraic
6433 equivalency of variable-sized arrays and alloca...
6435 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6437 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6438 a SCM boolean, not a C boolean.
6440 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6442 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6443 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6444 rules for raising scm_mtrigger. Previously, unfortunate but not
6445 unlikely circumstances could result in almost constant invokation
6446 of the gc. Now, this situations should be less likely, but they
6447 are not prevented completely.
6449 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6451 * numbers.c (scm_fuck): Procedure removed; looks like old test
6453 * numbers.h: Prototype removed.
6455 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6457 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6458 array to a pointer, to match my Nov 21 change in eval.c.
6460 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6462 * libguile.h: Added #include "libguile/backtrace.h", #include
6463 "libguile/stacks.h".
6465 * strings.c (scm_string scm_make_string scm_string_ref
6466 scm_string_set_x scm_string_equal_p scm_string_append):
6467 Bugfix according to scm patch from Aubrey Jaffer:
6468 Corrected long-standing
6469 (not (eqv? (integer->char 128)
6470 (string-ref (make-string 1 (integer->char 128)) 0)))
6471 bug found by John Kozak <jk@noontide.demon.co.uk>.
6473 * strports.c, strports.h: Make scm_eval_0str return the value of
6474 the last expression evaluated (previously, it returned void).
6476 * strports.c, strports.h: New function: scm_read_0str. Does what
6479 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6481 * simpos.c (scm_getenv): return #f if string can't be found in the
6482 environment instead of throwing an exception, for compatibility
6483 with numerous other systems.
6485 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6487 * Makefile.am (.c.x): Use guile-snarf.
6488 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6490 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6492 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6494 * backtrace.c (scm_display_error_message): Made non-static, and
6495 renamed from display_error_message.
6496 * backtrace.h (scm_display_error_message): Added extern decl.
6497 * throw.c (uncaught_throw): Use it to display the error message.
6499 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6501 * inet_aton.c: Use #if 0, not #ifdef 0.
6503 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6505 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6506 to convert the returned value.
6507 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6508 the offset argument.
6510 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6512 Add new interface to catch/throw, usable from C as well as
6514 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6515 (scm_internal_catch): New function, replaces...
6516 (scm_catch_apply): Deleted.
6517 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6518 mechanism which is a bit more code, but can be used nicely from C
6519 and implement the Scheme semantics as well.
6520 (scm_internal_catch): This is the replacement; it's named after
6521 the analogous function in Emacs.
6522 (scm_catch): Reimplemented in terms of the above.
6523 (struct catch_body_data, catch_body, catch_handler): New
6524 functions, used by scm_catch.
6525 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6526 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6527 support for new cwdr.
6529 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6532 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6534 * acconfig.h: Added DYNAMIC_LINKING symbol.
6535 * configure.in: Add option and checks for dynamic linking.
6536 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6537 dynl.h: New files for dynamic linking support.
6538 * Makefile.am (libguile_a_SOURCES):
6540 (modinclude_HEADERS): Added "dynl.h".
6541 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6543 * init.c (scm_boot_guile_1): Call
6544 scm_init_dynamic_linking to initialize dynamic linking support.
6546 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6548 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6549 (as we Schemers say). It needs to be global, so that I can tweak
6550 it for the proper operation of unexec.
6551 (scm_boot_guile_1_live): New variable, see above.
6553 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6555 * guile-snarf.sh: Removed.
6556 * PLUGIN/guile.libs: Added dependency for -lm.
6557 * acinclude.m4: Renamed from aclocal.m4.
6558 * PLUGIN/greet: Removed.
6559 * Makefile.am, aclocal.m4: New files.
6560 * configure.in: Updated for Automake.
6562 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6564 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6565 and not top_level_lookup_thunk_var.
6567 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6569 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6571 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6573 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6574 Scheme function, instead of syntax. Single argument is now a
6577 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6579 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6580 scm_ra_divide): Properly terminate statements passed as arguments
6581 to IVDEP macros. (Thanks to Bernard Urban.)
6583 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6584 with non-constant sizes. (Thanks to Bernard Urban.)
6586 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6588 It's an "eval closure", not an "eval thunk." A thunk is a
6589 function of no arguments.
6590 * root.h (struct scm_root_state): Renamed
6591 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6592 (scm_top_level_lookup_closure_var): Renamed from
6593 scm_top_level_lookup_thunk_var.
6594 * root.c (mark_root): Uses changed.
6595 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6596 * init.c (scm_start_stack): Uses changed.
6597 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6598 Change scheme-visible name to *top-level-lookup-closure* from
6599 *top-level-lookup-thunk*.
6601 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6603 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6604 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6606 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6608 * gc.c (struct scm_heap_seg_data): Doc fixes.
6610 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6611 sweeping. Then, prepend each segment's free cells to its
6612 freelist, rather than wiping out the old value. (Thanks to Marius
6615 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6616 scm_check_freelist, scm_debug_newcell): New functions and
6617 variables, for debugging freelist problems.
6618 * pairs.h (SCM_NEWCELL): New debugging version added.
6619 * gc.h (scm_debug_newcell): Added extern declaration, used by
6620 debugging version of SCM_NEWCELL.
6622 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6624 On some systems <libc.h> conflicts with <unistd.h>, and should not
6625 be #included at all.
6626 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6627 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6628 * configure.in: Call it.
6629 * posix.c, filesys.c: Use its results to decide whether or not to
6631 * configure, scmconfig.h.in: Rebuilt with autoconf and
6634 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6636 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6637 pointer to the stdio stream before calling scm_setbuf0, so the
6638 latter will be able to retrieve it. I'm surprised this didn't
6639 segfault earlier. (Thanks to Christopher Lee.)
6641 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6643 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6646 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6648 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6649 number of stack narrowing specifier pairs. The first specifier in
6650 a pair controls inner border, the second the outer border. A
6651 number means cut that number of frames, a procedure object means
6652 cut until that object is found in operator position in a frame.
6654 * root.c (cwdr): Bugfix.
6656 * read.c: Recording of positions disabled by default.
6658 * procs.c (scm_closure_p): New function.
6660 * posix.c (scm_tmpnam): New function.
6662 * load.c: Added #include "throw.h".
6663 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6666 * load.c, load.h (scm_read_and_eval_x): New function.
6668 * eval.c: Renamed debug option "deval" to "debug".
6670 (scm_eval_x): `eval!' is no longer accessible from the scheme
6671 level. Motivation: We can't allow operations which introduce
6672 glocs into the scheme level. Guile's type system can't handle
6673 these as data. Use `eval' or `read-and-eval!' as replacement.
6675 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6676 SCM_CONSP since this is a macro!; Set vframe.prev to
6677 scm_last_debug_frame instead of 0. In this way we can look
6678 "above" the virtual start stack frame if we wish.
6679 (scm_debug_hang): New function: Useful for debugging Guile in
6680 certain tricky situations. Will probably be removed later...
6682 * debug.h: Changed semantics of debug option "backtrace". This
6683 option now only indicates whether we want automatic backtrace at
6686 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6688 * ports.c: #include "filesys.h"
6689 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6691 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6692 Motivation: This is system specific code which is related to file
6693 I/O. It also may use select. Added code by Gary Houston to
6694 detect presence of character in stdio buffers.
6696 * libguile.h: #include "libguile/libpath.h"
6698 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6699 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6700 SCM_SITE_DIR; Install libpath.h among the other include files.
6702 * load.c, load.h (scm_sys_package_data_dir): New function.
6704 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6706 * stacks.h: Bugfix: Don't use tail-array length field as stack
6707 length field! This screwed GC.
6709 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6711 * _scm.h: Added #ifndef around definition of macros min and max.
6713 * __scm.h: Added hooks for threads to plugin to in ints protection
6714 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6715 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6716 the main code in these macros duplicated and spread over multiple
6717 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6718 SCM_THREAD_SWITCHING_CODE.
6720 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6722 * snarf.h: New file.
6723 * guile-snarf.sh: New file.
6724 * Makefile.in (inner_h_files): Added snarf.h
6725 (ancillary, install, uninstall, distclean): Added actions for
6727 (.c.x): Use guile-snarf.
6728 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6729 (gen_c_files): Note that these depend on guile-snarf.
6730 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6731 now in "snarf.h". Added #include "snarf.h" to get them.
6732 * libguile.h: Added #include "snarf.h".
6733 (Patches applied and tweaked by Jim Blandy.)
6735 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6737 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6738 standards suggest against providing prototypes for system
6739 functions. Thanks to Greg Troxel.
6741 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6743 * strports.c (scm_eval_0str): New function.
6744 #include "read.h", to get prototype for scm_read.
6745 * Makefile.in (strports.o): Update dependencies.
6746 * strports.h: New prototype.
6748 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6749 scheme name from "int?" to "integer?". It seems to do the job.
6750 * numbers.h: Rename prototype too.
6751 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6754 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6755 scm_num_eq_p): Rename these according to R4RS conventions: call
6756 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6757 to making libguile R4RS compliant without ice-9...
6759 * load.c (scm_sys_search_load_path): Search for files under all
6760 extensions listed in the %load-extensions variable. If FILENAME
6761 is absolute, return it unchanged, without searching the load path.
6762 (scm_loc_load_extensions): New variable, pointing to
6763 %load-extensions' value cell.
6764 (scm_init_load): Initialize it, and the value it points to.
6765 (scm_primitive_load_path): Improve error reporting.
6767 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6768 of new Scheme variable %load-hook.
6769 (scm_primitive_load): Apply %load-hook to filename.
6771 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6773 * configure.in: add tests for figuring out whether buffered data
6774 is available in a FILE structure, which is needed by char-ready.
6776 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6779 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6780 exceptions using misc_error instead of syserror. It seems a bit
6781 odd to throw an exception if a string can't be found in the
6782 environment, but it's consistent with open-file, stat etc.
6783 (simpos.h): remove sys_ from getenv.
6785 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6786 occurs, throw an error instead of returning errno. Return value
6788 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6790 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6792 * filesys.c (scm_stat2scm): derive file type and permissions from
6793 the stat mode and append them to the returned vector.
6794 There isn't much overhead in doing this and it avoids the need to
6795 work with S_IRUSR et al. in Scheme.
6796 Define symbols scm_sym_regular etc.
6797 (scm_init_filesys): don't intern S_IRUSR etc.
6799 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6800 and s_primitive_load_path.
6802 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6804 * error.h: don't declare error symbols. prototype for scm_misc_error.
6806 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6809 * error.c: use SCM_SYMBOL to set up error keys.
6810 scm_misc_error: new procedure.
6812 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6814 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6815 between `#!' and `!#' is ignored.
6816 (skip_scsh_block_comment): New function.
6818 * feature.c (scm_set_program_arguments): New argument, FIRST.
6819 * feature.h: Update prototype.
6820 * init.c (scm_boot_guile_1): Pass new argument to
6821 scm_set_program_arguments.
6823 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6825 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6826 (scm_boot_guile): Call scm_set_program_arguments here, later than
6827 the old initialization.
6829 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6830 initialization procedure.
6831 - Delete in, out, err arguments; there are other perfectly good
6832 ways to override these when desired.
6833 - Delete result argument; this function shouldn't ever return.
6834 - Rename init_func argument to main_func, for less confusion.
6835 - Delete boot_cmd argument; main_func is more general.
6836 -Add 'closure' argument, to help people pass data to main_func
6837 without resorting to global variables.
6838 - Abort if reentered; don't bother returning an error code.
6839 - Call scm_init_standard_ports to set up the default/current
6840 standard ports; no need to pass them to scm_start_stack.
6841 - Remove code to evaluate the boot_cmd, and start the repl; let
6842 the user do something like that in main_func if they want.
6843 - Remove code to package up a return value; main_func can do any
6845 - Call exit (0), instead of returning.
6846 (scm_start_stack): Don't initialize the I/O ports here; that's
6847 weird. Delete in, out, err arguments. Move guts to
6848 scm_init_standard_ports, scm_stdio_to_port.
6849 (scm_init_standard_ports): New function, to set up current and
6850 default standard ports.
6851 (scm_start_stack, scm_restart_stack): Make these static.
6852 * init.h (scm_boot_guile): Adjust declaration.
6853 (scm_start_stack, scm_restart_stack): Remove externally
6854 visible declarations for these.
6855 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6857 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6858 written out several times in scm_start_stack.
6859 * fports.h: New declaration for the above.
6861 * feature.c (scm_set_program_arguments): New function.
6862 * feature.h: New declaration for the above.
6864 * ports.c: Formatting tweak.
6866 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6868 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6869 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6870 for obtaining the address of a car or cdr field. Motivation:
6871 &SCM_CXR make assumptions about the internal structure of the
6874 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6875 Motivation: see SCM_CXRLOC.
6877 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6878 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6879 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6880 Motivation: Safer use. Some other macros are defined in terms of
6881 these operations. If these are defined using the SCM_SETCXR
6882 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6883 to inefficiency and an <e1> with side-effects could potentially
6884 break. Also, these particular operations are heavily utilized in
6885 the garbage collector. In unoptimized code there will be a
6888 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6889 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6890 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6891 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6892 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6893 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6894 vports.c: Cleaned up use of pairs: Don't make any special
6895 assumptions about the internal structure of selectors and
6896 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6897 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6898 (Among other things, this change makes it easier to build Guile
6899 with certain compilers which have problems with casted lvalues.)
6901 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6903 * stacks.c: Improve selection of relevant stack frames when making
6904 a stack object. Introduce one level of indirection in the stack
6905 object to make it possible to "narrow" to a certain region of the
6906 stack. This facilitates making use of more clever algorithms (not
6907 implemented) for selecting relevant frames and gives a cleaner
6908 design since selection of frames can be done independently of
6909 extraction of frames from the real stack.
6910 (scm_stack_id): Also take #t as argument which means look at
6913 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6914 Turn n_tail into an integer directly representing current number
6915 of frames in stack. Add field tail.
6917 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6919 * debug.c (scm_make_memoized): Made it available at scheme level.
6920 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6921 SCM_NIMP before applying heavier predicates in argument checking.
6922 (scm_local_eval): Also take memoized object as argument.
6924 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6925 aren't created with zero length, but should such a strange
6926 creature suddenly turn up...
6928 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
6930 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
6931 `del', for the sake of C++ compilers. (Patch applied by JimB.)
6933 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
6935 * variable.c (scm_make_variable): Make the name hint optional, as
6937 (anonymous_variable_sym): Renamed from variable_sym. All uses
6940 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
6941 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
6942 of scm_primitive_load_path was also changed to
6943 "primitive-load-path", from "%try-load-path". Callers changed.
6944 We'd like to respect the convention that a function named
6945 "try-mumble" should behave just like the function called "mumble",
6946 but return #f instead of signalling some error.
6947 * load.h: Rename prototypes.
6949 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6951 * print.c (make_print_state, grow_print_state), print.h: Modified
6952 the print state representation: Don't use a tail array for
6953 recording of circular references. Resizing of the print state
6954 structure invalidates the print state pointer. To avoid passing
6955 around an indirect print state reference to all printing
6956 functions, we instead let the print state reference a resizable
6959 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
6961 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
6962 Don't crash when passed an improper list terminated by a
6963 non-immediate value.
6965 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
6967 Allocate data for structures on an eight-byte boundary, as
6968 required by the tagging system.
6969 * struct.c (alloc_struct): New function.
6970 (scm_make_struct, scm_make_vtable_vtable): Call it.
6971 * struct.h (scm_struct_n_extra_words): Bump to 3.
6972 (scm_struct_i_ptr): New "field".
6973 * gc.c (scm_gc_sweep): When we need to free the data, use the
6974 information stored by alloc_struct to find the beginning of the
6975 block allocated to the structure, so we can free it.
6977 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6979 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
6982 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
6983 (scm_debug_info): New member: id.
6985 * stacks.c: Stacks are now represented as structs; Stacks have an
6986 id given to them by `start-stack'.
6987 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
6989 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
6990 Changed stack representation.
6992 * debug.c (scm_procedure_name): Try procedure property `name' for
6993 compiled closures aswell.
6995 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
6997 * eval.c: scm_i_name moved to gsubr.c
6998 (scm_m_define): Record names of all kinds of procedure
6999 objects. (Earlier, only closures were recorded.)
7001 * procprop.h: Added declaration of scm_i_name.
7003 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7004 (scm_make_gsubr): Record names of compiled closures.
7006 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7008 * debug.c, debug.h: Removed obsolete code.
7010 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7011 stacks.c: Renamed regs --> scm_contregs.
7013 * print.c (scm_free_print_state): Cleanup print state before
7014 returning it to pool. It is better to do it here than in
7015 scm_prin1 since scm_prin1 is called often.
7017 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7018 s_set_source_property_x): Check that first argument is a pair or a
7021 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7022 scm_i_line, scm_i_column and scm_i_breakpoint global.
7024 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7025 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7028 * debug.h: Added debug object smob declaration and macro
7031 * configure.in: Build with backtrace.o and stacks.o if debug
7034 * Makefile.in: Added entries for new files: backtrace.c,
7035 backtrace.h, stacks.c and stacks.h.
7037 * symbols.c (scm_sym2ovcell): Fixed documentation.
7039 * _scm.h (min, max): Added.
7041 * async.c: Moved `min' macro to _scm.h.
7043 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7044 SCM_BACKTRACE_INDENT.
7046 * eval.c: Added new debug options `maxdepth' and `indent'.
7048 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7050 * print.h: Added selector SCM_PRINT_STATE.
7052 * print.c: New functions: scm_make_print_state,
7053 scm_free_print_state.
7055 * print.h: Added declarations for scm_make_print_state,
7056 scm_free_print_state.
7058 * debug.c (scm_m_start_stack): New acro.
7060 * debug.h: Small cleanup.
7062 * init.c (scm_boot_guile_1): Moved scm_init_debug below

7087 declare functions with prototypes. (Patch thanks to Marius
7090 More prototype-related changes from Marius Vollmer:
7091 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7092 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7093 * ports.h (ptobfuns): Added prototypes. This means some casting in
7095 * fports.c: Added casts for initializations, since the functions
7096 are defined to take FILE * as their stream argument, not SCM.
7097 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7098 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7099 to `char *str_data' to conform to prototype.
7101 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7103 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7105 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7107 * stime.c, stime.h: use SCM_P method.
7109 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7111 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7112 be given at least two arguments. Insist that lst's last element
7113 be a list, but don't make any requirements of its predecessors.
7115 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7117 * eval.c (scm_nconc2last): Revert last change; there seems to be
7118 other stuff going on here.
7120 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7122 * eval.c (scm_nconc2last): Make sure that each element of lst
7123 (which is a list of argument lists, except for the tail) is a
7124 proper list, i.e., finite and terminated by '().
7126 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7128 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7131 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7132 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7135 * vectors.c (scm_make_vector): Fill vectors with the undefined
7136 value, to help make Guile Scheme code more portable to other
7139 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7140 * symbols.h, tags.h: Doc fixes.
7142 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7144 * async.c (scm_take_signal): Doc fixes.
7146 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7148 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7149 want to subtract it from the modulus; we just want to leave it
7152 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7154 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7157 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7159 * throw.c (scm_catch_apply): Finished implementation of
7162 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7164 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7166 (scm_init_filesys): set "i/o-extensions" feature.
7169 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7171 * Makefile.in (root.o): Correct dependencies.
7173 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7175 * Makefile.in: Added dependency entry for root.o.
7177 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7178 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7180 * init.c (scm_start_stack): Set initial root continuation number
7183 * procs.c: New function: scm_thunk_p.
7185 * procs.h: Added declarations of scm_thunk_p.
7187 * root.c: Renamed `call-with-new-root' -->
7188 `call-with-dynamic-root'.
7189 (cwdr): Removed allocation of new root state. This should be done
7190 separately by use of scm_make_root.
7191 (scm_apply_with_dynamic_root): New function: Does what it
7192 sounds like. Needed when spawning threads.
7194 * root.h: Added member last_debug_frame to root state.
7195 Added #include "libguile/debug.h"
7197 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7198 arguments. The motivation is that code in root.c needs catch
7199 functionality, and we want to avoid code duplication.
7200 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7201 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7202 handlers that run without popping the stack into the dynwind
7205 * throw.h: Added prototypes for scm_catch_apply and
7208 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7210 * root.h (scm_root, scm_set_root): Decouple thread support details
7211 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7212 SCM_SET_THREAD_LOCAL_DATA.
7214 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7215 and tortoise scanning loop.
7217 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7219 * Makefile.in: Rebuild dependencies.
7221 * libguile.h: #include "libguile/print.h" before "smob.h", since
7222 the latter uses the print_state structure.
7224 * throw.c (scm_ithrow): Use the correct variable when checking to
7225 see if a given element of scm_dynwinds is a valid catch.
7227 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7228 structure, abort; don't just silently ignore the garbage.
7230 * _scm.h: #include "print.h" here, since it seems to be used just
7232 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7233 strports.c, unif.h: Don't #include "print.h".
7235 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7237 * feature.h (scm_loc_features): Removed external declaration.
7238 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7240 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7242 * feature.c (scm_init_feature): Added threads feature (needs to be
7243 initialized here, since features doesn't exist when
7244 scm_init_threads is called).
7246 * libguile.h: Added #include "libguile/../threads/threads.h".
7247 (This is a kludge to get thread support working. This should be
7250 * configure.in, acconfig.h: Added flags for thread support.
7252 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7255 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7256 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7259 * _scm.h: Added conditional #include "threads.h"
7261 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7262 SCM_THREADS_SWITCHING_CODE.
7264 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7265 allocate the basic dynamic root object.
7266 (scm_boot_guile): Added call to scm_init_root.
7268 * root.c, root.h: Added root smob.
7269 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7270 functions: Implements dynamic roots mostly according to spec in
7271 SCM manual. Main difference is that the second argument is a
7272 throw handler rather than an error "thunk".
7274 * root.h: Added declaration of scm_init_root.
7276 * root.c: Added #include "genio.h", #include "smob.h", #include
7277 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7279 (scm_init_root): Added #include "root.x".
7281 * throw.c: Added #include "stackchk.h"
7282 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7283 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7284 can be used in scm_call_with_new_root; Added reenabling of stack
7285 checking when catching a throw.
7287 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7289 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7291 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7292 element is not found, as per R4RS.
7294 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7296 * list.c: Doc fixes throughout.
7298 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7300 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7301 declare the char * to be const. Avoids a warning in rgx.c.
7303 * ports.h: spelling fix.
7305 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7308 * load.c (scm_sys_try_load_path): throw an error if file not found
7309 (like it says it in NEWS).
7311 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7313 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7314 PROPS slot to '(), not #f; it's an empty alist.
7316 * throw.h, throw.c: Use SCM_P instead of #if hair.
7318 Remove special support for uncaught throws; see throw.c for
7320 * throw.c (uncaught_throw): New function.
7321 (scm_ithrow): Call uncaught_throw if we don't find a throw
7322 target; don't mess with scm_bad_throw_vcell.
7323 (scm_bad_throw_vcell): Variable deleted.
7324 (scm_init_throw): Don't initialize it.
7326 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7329 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7331 * numbers.c (scm_istr2int): If the number is short (as most
7332 numbers are), just call scm_small_istr2int to deal with it.
7333 (scm_small_istr2int): New function, created by un-#ifdefing the
7334 non-bignum version of scm_istr2int and renaming it.
7336 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7338 * load.c (scm_sys_try_load): don't check whether value returned
7339 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7340 Change the Scheme name from %try-load to primitive-load.
7342 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7343 Can avoid passing a message, allowing it to be derived in the
7344 error handler (e.g., if we want to throw to the key both from
7347 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7349 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7350 references now have a new appearance which is more compact and
7351 also gives a clue about what the target of the reference is.
7352 By setting parameters in the print state, more fancy printing can
7353 be achieved. This is used by the (not yet commited) backtrace
7356 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7358 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7361 * print.c: Added #include "struct.h". Removed function
7364 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7365 scm_iprin1. Removed prototype for scm_prlist.
7367 * arbiters.c (prinarb),
7368 async.c (print_async),
7369 debug.c (prindebugobj, prinmemoized),
7370 eval.c (prinprom, prinmacro),
7371 filesys.c (scm_fd_print, scm_dir_print),
7373 mallocs.c (prinmalloc),
7374 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7375 smob.h (scm_smobfuns),
7376 srcprop.c (prinsrcprops),
7378 unif.c, unif.h (scm_raprin1, rapr1),
7379 variable.c (prin_var): Changed argument `int writing' to
7380 `scm_print_state *pstate'.
7382 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7383 that it will be called before scm_init_print.
7385 * print.c (scm_prin1): Print states are now allocated when calling
7386 scm_prin1 and then passed around to all printing functions as an
7387 argument. A cache `print_state_pool' enables reuse of print
7389 (scm_make_print_state): New function.
7390 (scm_iprin1): Adaption to print states.
7391 (scm_iprlist): An initial "hare and tortoise" scan brings down
7392 time complexity to O (depth * N). (Better time complexity will be
7393 achieved when the printing code is completely rewritten.)
7395 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7397 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7398 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7399 it gets done whether or not the cache variable has a value.
7401 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7403 Distinguish #f and ().
7404 * __scm.h: #undef SICP.
7405 * pairs.h (SCM_EOL): Delete this definition, equating it with
7407 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7408 the value it used to have. Doc fixes, too.
7410 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7412 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7413 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7414 Lord's implementation of structs, allowing for tail arrays as
7415 described in the manual. Also fixed some bugs. (Both the interface
7416 and the implementation should be improved.)
7418 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7420 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7421 People who whish to see the source can do `(print-enable 'source)'.
7422 Removed #ifdef DEBUG_EXTENSIONS.
7424 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7426 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7427 integer (assuming for now accepting an integer is a good thing).
7429 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7430 %S will be used instead for write'ing arguments.
7432 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7433 asserts. fix a few other asserts.
7434 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7435 scm_uniform_vector_ref, scm_array_set_x,
7436 scm_dimensions_to_unform_array): change args in
7437 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7438 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7439 scm_substring_fill_x): likewise.
7440 gsubr.c (scm_gsubr_apply): likewise.
7441 eval.c (SCM_APPLY): likewise.
7443 * eval.c (4 places): replace scm_everr with lgh_error or
7446 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7447 scm_memory_error): new procedures.
7448 scm_everr: deleted. can use scm_wta, dropping first two args.
7449 scm_error: convert NULL subr to SCM_BOOL_F.
7451 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7454 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7457 * error.c, error.h: new error keys: scm_arg_type_key,
7458 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7460 scm_wta: reimplement using lgh_error instead of scm_everr.
7462 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7464 * gdbint.c: scm_lread now has one more argument.
7466 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7467 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7468 loading source from non-file ports, which, e. g., happens when
7469 using the Emacs interface).
7471 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7474 * read.c: Added code for recording of positions of source code
7475 expressions; New functions: recsexpr, scm_lreadrecparen;
7476 _scm_make_srcprops --> scm_make_srcprops
7477 (scm_flush_ws): Removed updating of positions counters. This work
7478 is already done by scm_gen_getc
7480 * read.h: Added prototype for scm_lreadrecparen
7482 * print.c: Added #include "alist.h"
7484 * eval.c: Added #include "hash.h"
7486 * eq.c: Added #include "ramap.h"
7488 * options.c: Documentation fixes.
7490 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7491 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7492 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7493 --> scm_make_srcprops
7495 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7496 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7497 function calls in the definition of the whash access macros.
7499 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7501 * init.c (scm_boot_guile): Add level of indirection to
7502 scm_boot_guile_1() to ensure that stack base pointer is properly
7503 initialized. There was no guarantee that variable i was the
7504 highest/lowest variable on stack (i.e. the call frame of
7505 scm_boot_guile was not completely protected from gc).
7507 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7509 * ports.h (scm_port_table): put back file_name, it will be used to
7510 support debugging. Undo related changes in fports.c, ioext.c,
7513 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7515 * ports.h (scm_port_table): remove file_name member for now, it seems
7517 * fports.c (scm_open_file): don't set file_name in PTAB.
7518 (prinfport): don't use file_name in PTAB.
7519 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7520 * ports.c (scm_add_to_port_table): don't intialize file_name.
7521 (scm_port_file_name): remove for now.
7522 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7524 * fports.h (scm_mkfile): prototype deleted.
7525 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7527 * debug.c, unif.c: use scm_out_of_range instead of
7528 wta for range errors (ASSERT still needs work).
7530 * error.c, error.h (scm_out_of_range): new procedure.
7532 * error.c, error.h (scm_out_of_range_key): new key.
7534 * posix.c (scm_sync): #else was missing.
7536 * error.c, error.h: append _key to names scm_num_overflow and
7539 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7540 of consing an empty list.
7541 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7542 of macros, saves code and string space.
7543 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7544 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7545 lower case. Rename scm_syserror_m to scm_syserror_msg.
7546 error.h: prototypes for new procedures.
7548 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7550 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7552 * error.c, error.h: setup scm_num_overflow key.
7554 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7555 Remove definition of SCM_OVSCM_FLOW.
7557 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7559 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7560 explicit message and args.
7562 * error.c, error.h, __scm.h: change system_error_sym to
7565 * error.c (system_error_sym): remove leading %% from the Scheme name
7568 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7570 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7572 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7573 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7574 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7575 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7576 renamed. (These were introduced by unsupervised name
7579 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7581 * print.c: Added code for detection of circular references during
7582 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7583 a hook for printing of closures (accessible via print options).
7584 This leads to a split of calls to scm_iprin1 into two classes:
7585 elementary print operations (e. g. the code which prints a smob)
7586 still use scm_iprin1 while top level calls (like scm_display) use
7587 scm_prin1. scm_prin1 begins by clearing the data structure used
7588 to record reference information.
7590 * print.h: Added declarations of scm_prin1 and scm_prlist.
7592 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7594 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7596 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7598 * error.c (err_head): scm_iprin1 --> scm_prin1
7600 * debug.c: Adjusted header comment.
7604 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7606 * strerror.c: Doc fix.
7608 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7610 * gdbint.c (gdb_read): Now possible to run during GC.
7611 (unmark_port, remark_port): New functions.
7613 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7615 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7616 of allocating a new string object. Also, increase size by
7617 the factor 2 instead of 1.5.
7619 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7621 * __scm.h (SCM_P): Corrected to run under traditional C.
7623 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7626 * async.c: Calls to scm_sysintern corrected.
7628 * async.h (scm_async_clock): Redundant declaration removed.
7630 * continuations.c (scm_dynthrow): Redundant declaration removed.
7632 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7633 Definition typos corrected.
7635 * debug.h: Missing declarations of functions in debug.c added
7638 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7639 Missing declarations to functions in eval.c added.
7641 * filesys.c: Possibly uninitialized variable rv.
7643 * gc.h (scm_object_addr, scm_unhash_name): Missing
7644 declarations of functions defined in gc.c added.
7646 * genio.c: Possible typos str_data -> wstr_data. ???
7648 * genio.c: Possibly unintended shadowing of local variable
7649 `int c' (gotos out of scope of inner `c'). ???
7651 * init.c: Uninitialized `SCM last' may be used.
7653 * ioext.h: (scm_sys_isatty_p): Typo.
7655 * list.h (scm_list_head): Missing prototype for function in
7658 * numbers.c (scm_two_doubles): Changed from extern to static
7659 (is used only within numbers.c).
7661 * numbers.h: Repeated declarations removed.
7663 * ports.h (scm_close_all_ports_except): Declaration for the
7664 function defined in ports.c added.
7666 * posix.h: Missing declarations added.
7668 * procs.h (scm_make_subr_opt): Missing declaration added.
7670 * socket.h (scm_sys_gethost): Missing declaration added.
7672 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7674 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7675 Missing declarations added.
7677 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7679 * struct.c: Uninitialized variable `SCM answer' may be used.
7681 * unif.c (l2ra): Declaration prototype.
7683 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7684 defined in ramap.c).
7686 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7687 Redundant declarations removed (they are in ramap.h).
7689 * variable.h (scm_make_udvariable,
7690 scm_make_undefined_variable): Declaration corrected to
7691 correspond variable.c.
7693 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7694 Missing declarations added.
7696 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7698 * Makefile.in (distclean): Don't forget to delete fd.h.
7700 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7702 * fd.h.in, tags.h: Trivial cleanups.
7704 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7705 marksweep.h just declared functions from gc.c.
7706 * gc.h, libguile.h: Don't #include "marksweep.h".
7707 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7708 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7709 dependencies updated.
7711 * libguile.h: Don't #include "files.h"; it's been deleted.
7713 * files.c (scm_sys_delete_file): Moved to filesys.c.
7714 File is now empty; deleted.
7716 * filesys.c: scm_sys_delete_file is now here. Remove
7717 #if's; they seem to rely on remnants of an old portability
7718 regimen. If the problems come up again, solve them properly,
7719 using autoconf. Specifically: Don't test M_SYSV, and #define
7720 remove to be unlink if it's #defined; don't use remove just
7721 because HAVE_STDC_HEADERS is #defined.
7722 * filesys.h: Add declarations for scm_sys_delete_file.
7723 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7724 files.o, files.h, files.c, and files.x.
7725 * init.c: Don't #include "files.h", and don't call scm_init_files.
7727 Use SCM_P instead of PROTO; the latter intrudes on the user's
7729 * params.h: Deleted; definition of SCM_P moved to...
7730 * __scm.h: ... here, where it replaces PROTO macro.
7731 * libguile.h, smob.h: Don't #include "params.h".
7732 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7733 smob.h: Fix prototypes accordingly.
7734 * Makefile.in: Update dependencies.
7735 (inner_h_files): Remove params.h.
7737 * gc.c: #include "gc.h"; every module should include its header,
7738 to let the compiler cross-check the declarations against the
7741 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7742 simpos.h: #include "libguile/__scm.h".
7744 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7746 * init.c: Don't forget to #include smob.h and init.h.
7747 * Makefile.in: Dependencies updated.
7749 * smob.h: Use PROTO instead of #if __STDC__.
7751 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7753 * __scm.h: Doc fixes.
7755 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7756 <angles>; this allows `make depends' to work properly.
7758 * libguile.h: #include smob.h and pairs.h before the others; they
7759 define typedefs used by other headers.
7761 C files should #include only the header files they need, not
7762 libguile.h (which #includes all the header files); the pointless
7763 recompilation was wasting my time.
7764 * Makefile.in (all .o dependency lists): Regenerated.
7765 * libguile.h: Don't try to get a definition for size_t here...
7766 * __scm.h: Do it here.
7767 * _scm.h: Since this is the internal libguile header, put things
7768 here that all (or a majority) of the libguile files will want.
7769 Don't #include <libguile.h> here; that generates dependencies on
7770 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7771 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7772 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

7873 * print.h, read.h: #include "options.h", since everyone who uses
7874 either of these files will need that.
7876 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7877 anyone who uses this file will need them to define the smob
7878 printing functions. Also, get markers.h, since people will need
7879 to #define the mark functions.
7881 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7882 * ports.h: ... to here.
7884 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7885 don't rely on archaic C default type rules.
7887 * fports.h: #include "libguile/ports.h", since you need that in
7888 order to parse this.
7890 * genio.h: #include "libguile/print.h", because you need that to
7891 parse this; don't bother #including "ports.h", since print.h gets
7894 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7896 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7897 this; it's now a reference to an element of *scm_root.
7899 * debug.h: Don't #include "options.h"; the compiler won't be able
7900 to find that once the headers are installed; instead, #include
7901 "libguile/options.h".
7902 * gc.h: Same, with marksweep.h.

7904 * scmhob.h: Same, with _scm.h.
7905 * smob.h: Same, with params.h.
7907 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7908 C files; there's no need for this, and it forces recompilations
7911 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7913 * error.c (scm_error): declare scm_error_callback.
7915 * error.h: prototype for scm_error_callback.
7917 * __scm.h: define lgh_error.
7918 (SCM_SYSERROR): redefine using lgh_error.
7920 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7922 * error.c (scm_error): new procedure.
7924 * error.h: prototype for scm_error.
7926 * Makefile.in (install): install scmconfig.h from the current
7927 directory, not $(srcdir).
7929 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7931 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7932 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7933 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

7939 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7940 vports.h, weaks.h: #include "libguile/__scm.h", not
7941 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
7942 dependencies are within libguile properly.
7944 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7946 * Makefile.in (.c.x): Simplify; there's no need to run this rule
7947 when scmconfig.h doesn't exist.
7949 * load.c (scm_sys_try_load): Correct spelling.
7951 * feature.c (scm_loc_features): Make this static.
7953 * Makefile.in (libpath.h): Omit trailing slash from path. We
7954 shouldn't require it of users, so why put it here?
7956 Move code to initialize and search %load-path from ice-9 to C
7957 code, so we can use the load-path to find the ice-9 boot code;
7958 this makes it easier to run Guile without installing it. See
7959 corresponding changes in guile/Makefile.in.
7960 * feature.c: Move stuff concerned with the load path to load.c.
7961 (scm_compiled_library_path): Deleted.
7962 Don't #include libpath.h here.
7963 * feature.h: Don't mention scm_compiled_library_path.
7964 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
7965 <sys/stat.h>, and <unistd.h> (if present).
7966 (R_OK): #define if the system hasn't deigned to.
7967 (scm_loc_load_path): New variable.
7968 (scm_init_load_path, scm_sys_search_load_path,
7969 scm_sys_try_load_path): New functions.
7970 (scm_init_load): Initialize scm_loc_load_path to point to the
7971 value cell of the Scheme %load-path variable.
7972 * load.h: Add declarations for scm_sys_search_load_path,
7973 scm_sys_try_load_path.
7974 * init.c: Call scm_init_load_path.
7975 * Makefile.in (feature.o, load.o): Dependencies updated.
7977 * load.c, load.h: Rewrite using PROTO macro.
7979 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7981 * gc.c (scm_cellp): New function: C predicate to determine if an
7982 SCM value can be regarded as a pointer to a cell on the heap.
7984 * gc.h: Added declaration of scm_cellp.
7986 * gdb_interface.h: New file: The GDB interface header from the GDB
7989 * gdbint.c: New file: GDB interface.
7991 * gdbint.h: New file: GDB interface.
7993 * libguile.h: Added #include <libguile/gdbint.h>.
7995 * init.c (scm_boot_guile): Added scm_init_gdbint.
7997 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
7998 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
7999 found if object files and source are kept separate).
8001 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8003 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8005 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8007 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8008 TK_SRC_DIR; they're not relevant any more.
8010 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8011 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8013 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8015 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8016 search path, so we can find the <libguile/MUMBLE.h> headers.
8018 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8020 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8021 implicit in the .c.o rule.
8022 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8025 Put the library path in a header file, instead of passing it on
8026 the command line in every compilation.
8027 * Makefile.in (libpath.h): New target.
8028 (feature.o): Depend on libpath.h.
8029 (clean): Delete libpath.h.
8030 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8031 * feature.c: ... #include "libpath.h" here.
8032 * .cvsignore: Ignore libpath.h.
8034 Don't install the unwashed masses of Guile header files in the
8035 main #include path; put most of them in a subdirectory called
8036 'libguile'. This avoids naming conflicts between Guile header
8037 files and system header files (of which there were a few).
8038 * Makefile.in (pkgincludedir): Deleted.
8039 (innerincludedir): New variable; this and $(includedir) are enough.
8040 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8041 (installed_h_files): Divide this up. Now this variable lists
8042 those header files which should go into $(includedir) (i.e. appear
8043 directly in the #include path), and ...
8044 (inner_h_files): ... this new variable says which files appear in
8045 a subdirectory, and are referred to as <libguile/mumble.h>.
8046 (h_files): List them both.
8047 (install): Create innerincludedir, not pkgincludedir. Put
8048 the installed_h_files and inner_h_files in their proper places.
8049 (uninstall): Corresponding changes.
8050 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8051 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8052 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8053 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8054 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8055 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8056 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8057 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8058 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8059 vports.h, weaks.h: Find __scm.h in its new location.
8060 * __scm.h: Find scmconfig.h and tags.h in their new locations
8061 (they're both "inner" files).
8063 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8065 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8067 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8069 * posix.c: Doc fixes.
8071 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8073 * socket.c: Don't include a prototype for inet_aton; just use a
8074 K&R style declaration, to avoid warnings but minimize the chance
8075 of conflicts with the system.
8077 On NextStep, <utime.h> doesn't define struct utime, unless we
8078 #define _POSIX_SOURCE before #including it.
8079 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8080 * acconfig.h: New comment text for above CPP symbol.
8081 * configure.in: Call it.
8082 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8084 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8086 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8087 testing for __EMX__.
8089 * posix.c: #include <libc.h>, if it exists.
8091 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8092 don't even know if the latter exists.
8094 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8095 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8096 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8098 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8100 (scm_init_posix): Use them when initializing the Scheme constants
8103 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8105 * Makefile.in (libdir, includedir, bindir): Use the
8106 autoconf-supplied values, instead of deriving them ourselves.
8107 (pkgincludedir, datadir, pkgdatadir): New variables.
8108 (install, uninstall): Put the header files in a special
8109 subdirectory, not in the main search path.
8111 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8112 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8114 * Makefile.in (IMPLPATH): Deleted; never used.
8116 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8117 on the Tcl/Tk source any more.
8118 (INCLUDE_CFLAGS): Remove references to the above.
8120 * Makefile.in (version.o): Corrected dependencies.
8122 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8124 * libguile.h: #include "version.h"
8126 * init.c (scm_boot_guile): Call scm_init_version.
8127 * gscm.c (gscm_run_scm): Call scm_init_version.
8129 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8130 GUILE_VERSION): AC_DEFINE these.
8131 (acconfig.h): #undef the above symbols.
8133 * Makefile.in (libobjs): Add version.o.
8134 (installed_h_files): Add version.h.
8135 (c_files): Add version.c.
8136 (gen_c_files): Add version.x.
8137 (version.o): New rule.
8138 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8139 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

8148 weaks.o): Add version.h to dependency lists.
8149 (markers.o): Remove duplicate rule.
8151 * version.h: New file.
8153 * version.c: New file.
8155 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8157 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8158 array; use it appropriately. Since GCC is quite happy to
8159 subscript functions, it never warned us about this; we should use
8160 -Wpointer-arith in the future. I guess we never tested
8163 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8165 * socket.c: Doc and copyright fixes.
8167 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8169 * debug.c: Fixed and improved gdb support.
8171 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8173 * socket.c: Added declaration of inet_aton to avoid compiler
8174 warning. (Hope this solution is correct.)
8176 * stime.c: Added declaration of ftime. (This is missing in
8179 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8181 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8183 * Makefile.in (c_files): add strerror.c.
8185 * strerror.c: new file from Emacs' sysdep.c.
8186 maybe configure should also check for sys_errlist.
8188 * configure.in (AC_REPLACE_FUNCS): add strerror.
8190 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8192 * debug.c (scm_init_debug): Added initialization for
8193 scm_evaluator_traps.
8195 * debug.h, debug.c: Various name changes.
8196 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8197 "debug-options-interface". See commentary in options.c.
8199 * options.h, options.c: Options now have documentation strings.
8200 Also added a long explanatory commentary.
8202 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8205 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8206 last_debug_info_frame is now updated in all cases.
8208 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8211 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8213 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8214 Added option STACK_CHECKING.
8216 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8218 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8220 * __scm.h: Removed symbols for debugging support.
8222 * acconfig.h: Added symbols for debugging support.
8224 * configure.in: Added user option for debugging support.
8225 --enable-debug will include the debugging code into libguile.a.
8227 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8228 scm_relocate_chunk_to_heap.
8230 * debug.c: New file: low-level debugging support. It also
8231 includes support for debugging with gdb. (The extensions to gdb
8232 are written by Per Bothner at Cygnus.)
8234 * debug.h: New file: low-level debugging support.
8236 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8237 argument pairs. Extensive modifications to the debugging
8238 evaluator. Added "SECTION:" commentaries to clarify what happens
8239 when, during double compilation. Renamed EVALIMP --> EVALIM.
8240 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8241 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8242 the beginning of the file. New procedure: scm_unmemocopy.
8243 Added some global state variables needed by the debugging
8244 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8245 check_entry, check_apply, check_exit, debug_options and
8246 evaluator_traps. New acro: undefine.
8248 * eval.h: Renamed EVAL --> XEVAL.
8250 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8251 --> scm_make_weak_key_hash_table.
8253 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8254 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8256 * libguile.h: Conditionally include debug.h
8258 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8259 scm_object_properties shouldn't return handle. `handle' now gets
8260 initialized in scm_set_object_properties_x. scm_object_properties
8261 doesn't any longer create an entry in scm_object_whash.
8263 * options.c: New file: handling of run time options.
8265 * options.h: New file: handling of run time options.
8267 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
8269 * print.c: New procedure: scm_print_options
8271 * print.h: Defines for print options.
8273 * read.c: New procedure: scm_read_options
8275 * read.h: Defines for reader options.
8277 * root.h: Added scm_source_whash among scm_sys_protects.
8279 * srcprop.c: New file: source properties.
8281 * srcprop.h: New file: source properties.
8283 * throw.c (jbsmob): Jump buffers are now correctly allocated.
8284 (Bug found by A. Green.)
8286 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8288 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8290 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8292 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8294 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8295 and should be called by the final client.
8297 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8299 * gc.h: Use the PROTO macro when declaring functions.
8300 * gc.c: Use the PROTO macro when declaring static functions.
8301 Remove the CPP hair around function definitions.
8303 * gc.c (scm_init_storage): Initialize scm_asyncs.
8305 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8306 preprocessor symbol; "__scm.h" is where it might get #defined.
8307 * __scm.h: Similar: #include <scmconfig.h> before testing
8310 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8312 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8314 * init.c (scm_boot_guile): Add init_func argument; call
8315 (*init_func) instead of calling scm_appinit; it's ucky to
8316 hard-code names for the user's procedures.
8317 * init.h (scm_boot_guile): Adjust declaration.
8319 * __scm.h (PROTO): New macro, for declaring functions with
8322 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8323 eliminate all the __STDC__ conditionals.
8324 (scm_boot_guile): Add declaration.
8325 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8326 Remove __STDC__ conditionals around function definitions; the
8327 declarations in init.h will provide the same information, more
8330 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8331 complain about it in the error message; the error message is
8332 adequate without that note, and there's nothing the user can do
8335 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8337 * Makefile.in (ancillary): Drop def.sed.
8339 * posix.c (scm_init_posix): Use numeric values, rather than
8340 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8341 F_OK. The symbols aren't available on some systems, and I'm
8342 pretty sure their values are fixed by common widespread practice.
8343 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8345 More functions unavailable on some systems.
8346 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8347 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8349 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8350 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8351 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8352 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8353 stub that signals an error as the #else.
8355 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8357 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8359 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8361 * unif.c: include ramap.h.
8363 * read.c (endif): case_insensative_p renamed case_insensitive_p.

8367 * ports.c: include sys/ioctl.h.
8369 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8371 * configure.in: check for sys/ioctl.h.
8373 * ports.c: include <malloc.h> not "malloc.h".
8375 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8377 * fports.c: remove ttyname and tmpnam declarations.
8379 * posix.c: fewer ttyname declarations.
8381 * fports.c: include <string.h> not "string.h".
8383 * init.c, ioext.c: include string.h and unistd.h.
8385 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8387 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8388 genio.c, simpos.c, vports.c: include string.h.
8390 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8392 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8394 (scm_addr_buffer_size): change type from scm_sizet to int.
8395 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8396 from scm_sizet to int.
8398 * error.c: include unistd.h.
8400 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8403 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8405 * __scm.hd, def.sed: deleted.
8407 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8409 Changes for NeXT, suggested by Robert Brown.
8410 * configure.in: Call AC_TYPE_MODE_T.
8411 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8412 NeXT. Put header file list in alphabetical order.
8413 * configure, scmconfig.h.in: Regenerated.
8414 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8416 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8419 * acconfig.h: New file, providing documentation for the CPP
8420 symbols defined in configure.in
8421 * acconfig-1.5.h: Removed; superceded by the above.
8423 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8425 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8427 * fports.c (scm_open_file): don't return #f, throw error.
8429 * ioext.c (fileno): renamed from %fileno.
8430 (soft-fileno): deleted.
8432 * ports.c (scm_port_revealed): don't need to check for -1 from
8434 (scm_set_port_revealed_x): return unspecified, not #f.
8436 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8438 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8440 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8442 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8444 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8446 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8447 This is necessary on Ultrix, and doesn't hurt portability.
8449 * Makefile.in (dist-dir): New target, implementing a new dist system.
8450 (installed_h_files): Put in alphabetical order.
8451 Remove duplicate entries for markers.h and unif.h.
8452 (c_files): Remove duplicate entries for markers.c.
8453 (ancillary): Renamed from anillery; all uses changed. Remove
8454 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8455 Remove all the ../doc/* files; doc/Makefile.in handles that.
8457 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8459 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8460 every if must have an else, or else the whole command has a
8461 non-zero exit code whenever the if's condition is false.
8463 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8465 * posix.c: include string.h.
8467 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8469 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8472 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8473 Remove leading % from scheme names.
8474 Do not return error values, call SCM_SYSERROR or similar.
8476 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8478 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8480 * struct.c (scm_init_struct): new file.
8482 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8484 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8485 (scm_list_head): added list-head for rapidly chopping argument
8486 lists off of longer lists (and similar).
8488 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
8490 * objprop.c (scm_object_property): assq the cdr of the whash
8491 handle for obj, not the handle itself.
8493 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8495 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8496 weak hash tables last of all marking to avoid an obscure gc bug.
8497 WARNING: circular lists stored in a weak hash table will hose us.
8499 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8501 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8502 new functions similar to scm_substring_move_left_x and
8503 scm_substring_move_right_x.
8505 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8507 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8510 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8512 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8514 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8516 * strports.c (scm_strprint_obj): convenience function. C for
8517 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8519 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8520 removed to a separate library
8522 * init.c (scm_boot_guile): copied from guile-tcl.c.
8523 Initialization specific to tcl interpreters removed.
8525 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8527 * ports.c (scm_ports_prehistory): size malloced here doesn't
8528 matter so long as it is non-0 (got rid of "* 4").
8530 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8532 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8533 since its definition was bogus).
8535 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8537 * mallocs.[ch]: back again (for rx at least).
8539 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8541 * ports.c: removed functions relating to the mapping between ports
8542 and descriptors. (That stuff is unix-specific and should be collected
8543 in a separate library).
8545 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8546 (Tom Mckay@avanticorp.com)
8548 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8550 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8551 handled correctly (SCM_FREEP was applied to them) -- test for
8552 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
8553 being overwritten with #f. (brown@grettir.bibliotech.com)
8555 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
8557 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

8560 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
8562 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak

8567 * list.c (scm_last_pair): map '()=>'()
8569 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>

8572 Generalized assoc and hash-table functions.
8573 Factored pairs.c into multiple files.
8575 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
8577 * gscm.c (gscm_run_scm): got rid of objprop.
8579 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
8581 * genio.c (scm_getc):
8582 NOTE: fgetc may not be interruptable.
8584 * procprop.c (scm_stand_in_scm_proc):
8585 NOTE: don't use a alist here.
8586 (scm_set_procedure_properties_x): fix type checking throughout this file.
8588 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
8590 * ports.c (scm_remove_from_port_table): adjust scm_mallocated

8595 * strports.c (scm_mkstrport):
8596 * vports.c (scm_make_soft_port): allocate a port table entry
8597 (possibly triggering gc) before setting the tag of the corresponding
8600 * pairs.c (scm_delq_x): never throw an error.
8602 * vectors.c (scm_make_vector): made the default vector fill argument
8603 into '() (much more useful than the previous value, "#unspecified")
8605 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
8607 * ports.c (scm_add_to_port_table): Added fields
8608 to port table entries: file_name, line_num, col.
8609 Update these in open_file, gen_getc and gen_ungetc.
8610 Added procedures to access those fields.
8612 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
8614 * procs.c (scm_make_subr_opt): new entry point for making
8617 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
8619 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
8621 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
8623 * numbers.c (scm_exact_p): This function no longer
8624 implements "integer?".

8628 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
8629 (scm_gc_stats): return an assoc of useful data. Replaces "room"
8630 and the stats reporting formerlly built into repl.

8633 GC statistics keeping moved to gc.c.
8634 Other statistics keeping can be done from Scheme.
8635 REPLS are now written in Scheme.
8637 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
8639 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky

8642 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
8644 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
8646 * feature.c (scm_compiled_library_path): moved here from repl.c.
8647 This file is for stuff relating specifically to Scheme libraries
8650 * eval.c (scm_m_define): don't give warning about redefinition, don't
8653 NOTE: this should throw a resumable exception with parameters --
8654 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
8656 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
8658 * error.c: scm_warn eliminated.

8670 between the call to procedurep and use.
8672 * error.c (scm_everr):
8674 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
8677 * strports.c: don't reveal the port's string to the caller
8678 because it changes size.
8680 (stputc stwrite): check/change the strings length with interrupts
8683 * objprop.c (scm_set_object_property_x &c): use the generic
8684 hashing functions and be threadsafe.
8686 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
8687 (per suggestion jaffer@gnu.ai.mit.edu).
8689 * mbstrings.c (scm_multi_byte_string): guard against argument list
8692 * strings.c (scm_make_string): loop cleanup
8694 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
8697 * weaks.c (scm_weak_vector): guard against argument list
8700 * variable.c (scm_builtin_variable): check for/make a built-in
8703 * vectors.c (scm_vector): while filling the new array,
8704 guard against a list of fill elements that grows after
8705 the vector is allocated.
8707 * hashtab.c -- new file: general hash table
8708 functions. hash, hashq, hashv, hashx.
8710 * tags.h: made wvect an option bit of vector.

8714 * symbols.c: made the basic symbol table operations atomic.
8716 * root.c &c.: collected stack-specific global state.
8717 linum/colnum etc *should* be port-specific state.
8719 * struct.c (scm_init_struct): init the first struct type during
8720 initialization to fix a race condition.
8722 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
8723 object, not in a global.
8724 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
8726 * throw.c (_scm_throw): Pass throwval on the stack, not in a global
8727 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
8729 * *.[ch]: namespace cleanup. Changed all (nearly) exported CPP
8730 and C symbols to begin with SCM_ or scm_.

8741 * async.c: New support for interrupt handlers.
8743 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
8745 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
8746 set the multi_byte flag correctly in symbols. This is wrong.
8747 intern_obbary_soft and msymbolize should take an extra parameter.
8748 Also, weird multibyte symbols don't print correctly.
8749 The weird symbol syntax is also a bit bogus (emacs doesn't quite
8752 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
8754 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
8755 use the system symhash. == #t means create an uninterned symbol.
8757 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
8759 * strings.c (scm_make_shared_substring): build'em.
8760 It might better to keep a table of these and use one
8761 less cons-pair per shared-substring.
8763 Tue Feb 6 17:45:21 1996 Tom Lord <lord@beehive>
8765 * strings.c (scm_string_shared_substring): create shared

8808 * strop.c (scm_i_rindex, scm_i_index): Don't use the BSD functions
8809 index/rindex. Do handle embedded \000 characters.
8811 Sun Jan 28 13:16:18 1996 Tom Lord <lord@beehive>
