1 1999-09-18 Gary Houston <ghouston@freewire.co.uk>
3 * _scm.h, scmsigs.c: replace HAVE_RESTARTS with
4 HAVE_RESTARTABLE_SYSCALLS.
6 * strports.c (scm_strport_to_string): create the string from
7 pt->read_buf instead of an expression that evaluates to the
10 * gdbint.c (gdb_print): don't just use SCM_CHARS to get a C string
11 from the port: the port's buffer may not be NUL terminated.
13 1999-09-16 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
15 * Makefile.am (.c.x): Added missing semicolon after `false'.
17 1999-09-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
19 * print.c (scm_iprin1): Turn `write' and `display' into
20 primitive generics and use their associated generic functions in
21 scm_iprin1 for GOOPS objects.
23 * backtrace.c: #include <unistd.h> if present.
25 1999-09-14 Jim Blandy <jimb@savonarola.red-bean.com>
27 * Makefile.am (.c.x): Don't create a subshell just to delete the
28 .x file and return false.
29 * Makefile.in: Regenerated.
31 1999-09-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
33 * feature.c (scm_create_hook): New function. Replaces
34 scm_make_named_hook which is now deprecated.
35 (scm_make_hook_with_name): New primitive.
36 (print_hook): Hooks now print in a fancy way.
38 1999-09-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
40 * __scm.h, backtrace.c, backtrace.h, debug.c, debug.h, dynl-dld.c,
41 dynwind.c, dynwind.h, eval.h, evalext.c, evalext.h, feature.c,
42 feature.h, hashtab.c, hashtab.h, objects.c, objects.h, print.c,
43 procs.c, procs.h, smob.c, smob.h, srcprop.c, strorder.c, struct.c,
44 struct.h: Updated copyright notices.
46 * srcprop.c (scm_source_property): Bugfix: Use SCM_NECONSP instead
47 of SCM_NCONSP. (Thanks to Greg Badros.)
49 * gsubr.c (scm_make_gsubr): Use scm_make_subr_opt for creation of
52 * eval.c, debug.h (SCM_BACKTRACE_WIDTH): New debug option: width.
54 * backtrace.c: Keep backtraces within specified width by
55 adaptively adjusting fancy printing parameters and cut output if
57 (scm_display_application): Check args.
59 1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
61 Change the name of the objects returned by OPENDIR from
62 "directory" to "directory stream". A predicate named "directory?"
64 * filesys.c (scm_directory_stream_p): Renamed from scm_directory_p.
65 At the Scheme level, "directory?" -> "directory-stream?".
66 (scm_dir_print): Use the phrase "directory stream" in printed form.
67 * filesys.h (scm_directory_stream_p): Prototype renamed
70 * Makefile.am (CLEANFILES): Remove versiondat.h; that should only
71 be removed by `make distclean', since it's generated by configure.
72 * Makefile.in: Regenerated.
73 (Thanks to Robert Bihlmeyer.)
75 * strop.c (scm_substring_move_x): Signal an error if start1
76 doesn't come before end1. (Thanks to Karoly Lorentey).
78 * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
79 calling SCM_NIMP. (Thanks to Karoly Lorentey).
81 * version.c (scm_libguile_config_stamp): Deleted. See
82 corresponding change to ../ice-9/boot-9.scm.
83 * versiondat.h.in: Remove definition for GUILE_STAMP.
84 * version.h: Delete prototype.
85 * Makefile.in: Regenerated.
87 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
89 * filesys.c (scm_directory_p): new procedure "directory?" Returns
90 a boolean indicating whether its argument is a directory
91 port as returned by opendir (thanks to Dirk Herrmann for the
94 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
96 * backtrace.c (display_frame_expr): Don't print a newline.
97 (display_frame): Print the newline here instead.
98 (display_backtrace_body): Don't print "Backtrace:".
99 (scm_backtrace): Print "Backtrace:" here instead.
101 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
103 * procs.c (scm_setter): Signal WTA if handed an entity or operator
106 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
107 primitives. (Thanks to Greg Badros);
108 (scm_hook_to_list): New primitive; Hooks are now smobs.
110 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
112 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
113 of #f for the 10th vector element to avoid an exception
114 seen by Bernard Urban.
115 (scm_mktime): unneeded ASSERT removed.
117 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
119 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
122 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
124 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
126 * numbers.c: Converted comparison operations to dispatch on
127 generic if args don't match.
129 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
131 1999-09-06 James Blandy <jimb@mule.m17n.org>
133 * guile-snarf.c: Deleted. Snarfing should respect CPP
134 conditionals, so it needs to actually run CPP. Bleah.
136 1999-09-05 James Blandy <jimb@mule.m17n.org>
138 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
139 * guile-snarf.in: Be sure to exit with an error if CPP does.
140 * Makefile.am (.c.x): Delete the .x file and exit with an error
141 status if guile-snarf exits with an error status.
142 * Makefile.in: Regenerated.
144 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
145 scm_makekey, which doesn't exist any more. Guess nobody's using
148 * guile-snarf.c: New implementation of guile-snarf, meant to be
149 more robust than the shell script. I think it's complete, but I
150 haven't tested it at all, and I haven't changed the build process
151 to actually use it. We should compare its output against that of
152 the existing shell script, for all source files.
154 * guile-snarf.c (parse_args): Abort if we haven't handled some
157 1999-09-03 James Blandy <jimb@mule.m17n.org>
159 * load.c (scm_search_path): If the filename has any extension at
160 all, ignore the entire list of extensions. Also, don't check whether
161 the file is accessible. If the file exists, accessible or not, we
162 should return it. Inaccessible files should cause an error later.
163 (Thanks to Keisuke Nishida for the suggestions.)
165 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
167 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
168 atexit not available. (sunos4.1.4 needs it.)
170 1999-09-01 James Blandy <jimb@mule.m17n.org>
172 I take it all back --- bcopy does handle overlapping source and
173 destination areas correctly. At least on every system I could
174 find. But it is better to use AC_REPLACE_FUNCS than to introduce
175 new CPP conditionals.
176 * memmove.c: New file, implementing memmove in terms of bcopy.
177 * scmconfig.h.in: Regenerated.
179 Allocators should use the `void *' type for generic pointers.
180 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
181 argument and return types.
182 * gc.h: Corresponding changes to prototypes.
185 1999-08-31 James Blandy <jimb@mule.m17n.org>
187 * numbers.c (scm_init_numbers): Claim to support the `complex'
188 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
190 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
191 find (ice-9 boot-9) when Guile was compiled in a separate
192 directory from the source. (Thanks to Rodney Brown.)
193 * Makefile.in: Regenerated.
195 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
196 table lengths by the size of a single element when growing the
197 table. (Thanks to Bill Schottstaedt.)
199 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
201 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
202 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
203 since that cuts down the time for type dispatch by 50%.
205 1999-08-30 James Blandy <jimb@mule.m17n.org>
207 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
208 not a correct substitute for memmove, because it doesn't handle
209 overlapping source and destination areas on many platforms.
210 Overlaps are the primary reason to use memmove in the first place.
211 * ports.c (scm_ungetc): Same.
212 * strop.c (scm_substring_move_x): Same.
214 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
216 * gc.c (scm_init_storage): Skip registration of cleanup on systems
217 which lack atexit. (Is it important that cleanup is made
218 properly? Maybe we should replace all `exit' with `scm_exit' and
221 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
222 scm_struct_free_standard, scm_struct_free_entity): Declared to
223 return scm_sizet instead of size_t.
225 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
226 there on sunos4.1.4.)
228 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
230 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
231 Account for the case when second argument is unbound.
233 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
234 (Thanks to Karoly Lorentey.)
236 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
237 isn't present. (Thanks to Suzuki Toshiya.)
239 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
242 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
245 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
246 Bernard Urban and Ian Grant.)
248 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
249 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
250 change in the representation of entities and operators.)
252 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
254 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
255 don't allocate zero bytes (thanks to Bill Schottstaedt).
257 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
259 * procs.c (scm_setter): Converted to use generic dispatch.
261 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
264 * load.c (scm_search_path): Don't try extensions which already are
265 present at the end of the filename.
266 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
268 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
270 Cleanup and simplification of generic method dispatch.
271 Also, the quadruple representation of entity and operator
272 procedures has been replaced with single.
274 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
276 * print.c (scm_isymnames): Removed #@hash-dispatch.
278 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
279 from eval.c; Support 0 arity methods.
280 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
281 (scm_apply_generic_env): Removed.
282 Replaced slots proc0-3 with procedure.
284 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
285 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
286 SCM_OPERATOR_PROCEDURE.
287 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
288 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
290 * struct.c, struct.h: Replace 4 procedure slots with one.
291 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
293 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
296 * eval.c (scm_sym_args): Removed.
297 (SCM_CEVAL): Simplified entity application.
298 Moved dispatch code to objects.c.
300 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
302 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
304 * sort.c (closureless): Use scm_eval_body.
306 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
307 with a symbol as last form was first called normally and then via
308 `map' or some other mechanism using primitive apply, an ILOC was
311 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
313 This change extends the representation of primitive procedures
314 with more data fields, e.g. a place for documentation and true
315 procedure properties.
317 * procs.c, procs.h (scm_subr_entry): New type: Stores data
318 associated with subrs.
319 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
320 SCM_SUBR_DOC): New macros.
321 (scm_subr_table): New variable.
322 (scm_mark_subr_table): New function.
324 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
326 * gc.c (scm_gc_mark): Don't mark subr names here.
327 (scm_igc): Call scm_mark_subr_table.
330 This change implements a scheme for letting a generic work as a
331 shadow for a primitive procedure. If the primitive procedure
332 can't dispatch on its arguments, control is left over to the
333 generic. Normal wrong type arg errors will be generated until the
334 user has hung the first method on the primitive.
336 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
338 * procs.c, procs.h (scm_subr_p): New function (used internally).
340 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
342 * objects.c, objects.h (scm_primitive_generic): New class.
344 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
346 * print.c (scm_iprin1): Print primitive-generics.
348 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
349 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
351 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
352 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
353 primitives). NOTE: This means that it is now *required* to use
354 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
355 obscured representation that will be removed in the future anyway,
356 so backward compatibility is no problem here).
358 * numbers.c: Converted most numeric primitives (all but bit
359 comparison operations and bit operations) to dispatch on generic
363 Better support for applying generic functions.
365 * eval.c, eval.h (scm_eval_body): New function.
367 * objects.c (scm_call_generic_0, scm_call_generic_1,
368 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
372 Optimization of the generic function dispatch mechanism.
374 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
375 called scm_memoize_method instead of doing a second lookup.
377 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
382 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
383 scm_sysintern so that the binding connected with the subr name
384 isn't cleared when we give set = 0.
387 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
389 More transparent handling of ports with print states.
391 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
392 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
393 instead of a pair of a port and a print state. We'll need to cons
394 once extra in scm_printer_apply but the type system will be
395 cleaner, it will mix better with GOOPS, and, it will be even more
396 transparent to the user.
398 * print.c (scm_get_print_state): New procedure: Given an output
399 port, return the print state associated to it in the current print
400 chain, if one exists;
401 (scm_port_with_print_state): New procedure: Associate a
402 print-state with a port.
403 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
404 (scm_printer_apply): Wrap port and pstate as a smob;
405 (print_state_printer): Removed.
407 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
409 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
412 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
413 testing (otherwise the port-print-state trick won't be transparent
414 to the user; one example where this caused problems was in the
415 (ice-9 format) module).
417 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
419 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
420 SCM_UNSPECIFIED instead of the set value.
422 1999-08-20 James Blandy <jimb@mule.m17n.org>
424 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
426 * ports.h (enum scm_port_rw_active): New enum, containing
427 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
428 zero). The debugger knows about enums, but doesn't know about
430 (typedef scm_port): Declare rw_active member to be an enum
432 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
434 * ports.c (scm_add_to_port_table): Same.
435 * strports.c (st_flush, st_end_input): Same.
437 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
438 scm_must_realloc, and scm_done_malloc as appropriate.
440 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
442 * sort.c (quicksort): Added condition to protect the algorithm
443 from crashing the interpreter if the less predicate is buggy.
445 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
447 * fports.c (fport_write): fix line-buffering mode again.
448 (scm_open_file): recognise 'l' for line-buffering.
449 (scm_setvbuf): recognise _IOLBF for line-buffering.
451 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
453 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
456 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
459 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
461 * fports.c (fport_write): use memcpy instead of strncpy, in case
462 the data contains NUL.
464 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
466 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
468 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
469 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
470 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
471 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
472 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
473 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
474 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
475 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
476 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
477 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
478 scm_sym_ as prefix for symbols.
480 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
482 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
483 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
484 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
485 scm_sym_atcall_cc): Made global.
487 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
489 * eval.c (scm_sym_args): Made global.
491 * objects.c (scm_set_object_procedure_x): Disallow setting of
492 procedures for pure generic functions.
494 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
496 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
497 Scheme name from lseek to seek, but lseek was added recently so
498 it shouldn't be a big problem.
499 * ports.c, gdbint.c, ioext.c: changed callers.
501 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
503 * fports.c (fport_input_waiting): if select is used, return 1
504 instead of whatever FD_ISSET expands to. maybe it will be useful
505 to interpret the value from the input_waiting ptob procedure as a
506 lower bound on the number of bytes available.
508 * Mikael asked for a few names to be changed...
510 * ports.c (scm_make_port_type): take the write procedure as the
511 second argument instead of the flush procedure.
512 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
513 fflush -> flush, read_flush -> end_input, fclose -> close,
514 fill_buffer -> fill_input, ftruncate -> truncate,
515 input_waiting_p -> input_waiting.
517 * ports.c (end_input_void_port): was read_flush_void_port.
518 (scm_set_port_end_input): was scm_set_port_flush_input.
519 (scm_set_port_flush): was scm_set_port_write.
520 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
521 (scm_end_input): was scm_read_flush.
522 (scm_fill_input): was scm_fill_buffer.
523 (scm_flush): was scm_fflush.
524 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
525 (fport_end_input): was local_read_flush.
526 (fport_flush): was local_fflush.
527 (fport_close): was local_fclose.
528 (fport_truncate): was local_ftruncate.
529 (fport_seek): was local_seek.
530 (fport_free): was local_free.
531 (fport_fill_input): was fport_fill_buffer.
532 * strports.c (st_end_input): was st_read_flush.
533 (st_truncate): was st_ftruncate.
534 * vports.c: (sf_flush): was sfflush.
535 (sf_close): was sfclose.
536 (sf_fill_input): was sf_fill_buffer.
538 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
541 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
543 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
544 forms now contain the expressions to be dispatched upon instead of
545 depending on a surrounding lambda or let; Generic function
546 dispatch has been optimized; `apply' on a generic function now
547 works a little bit strangely. It uses a trick so that the type
548 dispatch code in SCM_CEVAL can be reused.
550 * objects.h, objects.c (scm_apply_generic_env): Added (used by
552 (scm_operator_p): Added.
553 (scm_sym_atdispatch): Added.
554 (scm_set_object_procedure_x): Modified to handle the new style
556 (scm_object_procedures): New debugging procedure.
558 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
560 * eval.c, eval.h (scm_sym_args): Added.
562 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
564 * feature.c, feature.h (scm_c_run_hook): Added.
566 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
567 cdrxnoap and loopnoap instead of begin and loop.
569 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
571 * ports.c (scm_putc, scm_puts),
572 * unif.c (scm_uniform_array_write): use scm_lfwrite.
573 * ports.c (scm_putc): change type of first argument from int to char.
575 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
577 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
578 SCM_IM_HASH_DISPATCH.
580 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
581 (scm_si_redfined, scm_si_hashsets): Moved.
583 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
584 flag which combines type and status info so that the class
585 redefinition protocol has zero cost during normal execution.
587 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
589 * ports.h (scm_ptob_descriptor): include a write procedure again.
590 it's more efficient for unbuffered fports (e.g., sockets.)
592 * ports.c (scm_puts): use ptob->write.
593 * vports.c (scm_make_sfptob): set write proc in ptob.
594 * strports.c (scm_make_stptob): set write proc in ptob.
595 * ports.c (write_void_port): new procedure.
596 * vports.c (sf_write): new procedure.
597 * ports.c (scm_lfwrite): use ptob->write.
598 * strports.c (st_write): new procedure.
599 * fports.c (fport_write): new procedure.
600 (scm_make_fptob): set write in ptob to fport_write.
601 * ports.h: prototype for scm_set_port_write.
602 * ports.c (scm_make_port_type): initialise ptob write procedure.
603 (scm_set_port_write): new proc.
605 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
607 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
608 until we've verified that it is actually a port. (Thanks to
611 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
613 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
614 code, particularly an unnecessary test (len != size, where len ==
615 size). (Was this leftovers from debugging code, or have I missed
618 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
619 size. (Thanks to James Dean Palmer.)
621 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
622 (Thanks to Lorentey Karoly.)
624 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
626 * eval.c (scm_m_expand_body): Use scm_cons_source.
628 * struct.c (scm_print_struct): Use vtable name.
630 * print.c (scm_init_print): Set name of print state type.
632 * stacks.c (scm_init_stacks): Set name of stack type.
634 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
636 * eval.c (SCM_CEVAL): Removed old implementation of internal
639 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
641 * debug.c, debug.h (scm_reverse_lookup): Added.
642 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
643 internal procedure definitions; Don't use scm_i_inner_name.
645 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
648 * eval.h: Added prototypes for multi language support functions.
650 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
651 improper lists in the low-level representation, since that will
652 cause a begin to be prepended at macro expansion.
654 * eval.c (scm_cons_source): Version of cons which copies source
655 properties from an existing cell.
656 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
658 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
659 procedure source before calling scm_unmemocopy instead of faking
662 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
664 Ported `internal defines' fix from SCM. Original ChangeLog entry:
666 1998-07-09 Radey Shouman <radey@colorage.com>
668 * eval.c (ceval_1): Modifications to allow rewriting of interal
669 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
670 body of which it is the CAR is macro expanded by m_expand_body,
671 which rewrites internal DEFINE.
673 (m_expand_body): Added.
675 (m_macroexp1): Added argument to control error checking:
676 m_expand_body may speculatively expand forms in the wrong
677 environments. Made argument number checks conditional on
680 (m_body): Added, error checks bodies and inserts the ISYM tokens.
682 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
685 (m_cond): (m_case): (m_quote): Modified to avoid destructively
686 changing their argument forms. Since m_expand_body
687 speculatively macro expands forms the process must be
690 (m_ident_eqp): Fixed to use proper environment.
692 (renamed_ident): Added DEFER_INTS_EGC.
694 Added prototypes for static functions.
700 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
701 is false, do not produce an error for unbound variables, return a
702 pointer to cell_undef instead.
704 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
708 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
709 destructively changing their argument forms. Since m_expand_body
710 speculatively macro expands forms the process must be reversible.
712 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
713 SCM_IM_LET introduced by named lets.
715 (scm_m_letstar): Use scm_m_body instead of bodycheck.
717 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
718 scm_letrec. scm_letrec1 does not check for a null binding and
719 takes an additional argument to specify the ISYM of the body. Use
720 scm_m_body instead of bodycheck.
722 (scm_m_let): Use scm_m_body instead of bodycheck.
724 (scm_m_expand_body, scm_macroexp): New.
726 (unmemocopy): Account for ISYMs introduced by scm_m_body.
728 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
729 check=1. Throw error for internal defined that have not been
730 rewritten by scm_m_expand_body.
732 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
733 Removed prototype for SCM_APPLY.
735 * tags.h: Added extern declaration of scm_isymnames.
737 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
739 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
741 * lang.c: New file: Beginning of multi-language support.
743 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
745 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
746 (scm_dynamic_wind): Added argument checking for the after guard so
747 that we don't add garbage on the dynwind chain.
748 (scm_swap_bindings): Added.
750 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
751 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
752 (scm_isymnames): New isyms for multi-language support.
754 * eval.c (scm_nil, scm_t): New symbols.
755 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
756 forms for multi-language support.
758 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
760 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
762 Renamed functions in the random function library interface
763 from scm_i_XXX --> scm_c_XXX.
765 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
767 * ports.c (scm_putc): fix line-buffering.
769 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
771 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
772 scm_set_ptob_XXX --> scm_set_port_XXX.
774 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
776 * ports.c, ports.h (scm_make_port_type): New interface for
777 creation of port types (replaces scm_newptob). Just as for the
778 smobs, we need to separate the internal representation of smob
779 types from the interface, so that we easily can add new fields and
780 rearrange things without caring about backward compatibility.
781 This change was forced by the need in GOOPS to create classes
782 representing port types.
783 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
784 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
785 scm_set_ptob_seek, scm_set_ptob_truncate,
786 scm_set_ptob_input_waiting_p): New setters.
787 (scm_newptob): Rewritten to use scm_make_port_type. For backward
789 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
790 (scm_prinport): Removed.
791 (scm_port_print): Added.
792 (scm_print_port_mode): Added.
793 (void_port_ptob, print_void_port, close_void_port, noop0):
794 Removed. Removed #include "genio.h" Added #include "objects.h",
797 * fports.c (prinfport): Moved code from ports.c.
799 (scm_fptob): Removed. Instead use new interface.
800 (scm_make_fptob): Added. (Need to create basic ports in a
801 specific order in ports.c.)
803 * strports.c (scm_stptob, prinstpt, noop0): Removed
804 (scm_make_stptob): Added.
806 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
807 (scm_make_sfport): Added.
809 * filesys.c (scm_dir_print): Don't use the port printing code.
810 Instead provide specific directory printer.
812 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
814 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
817 * smob.c (scm_smob_print): Handle non-existing type name nicely.
818 Removed #include "genio.h"
820 * objects.c (scm_make_port_classes): New function ptr.
822 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
824 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
826 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
827 allow the 1st argument to be a fdes or filename as well as a
828 port (as in the filesys.c version).
830 * filesys.c (scm_truncate_file): removed.
832 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
834 * readline.c, readline.h: Removed.
836 * objects.c, objects.h (scm_port_class): Added.
837 (scm_class_of): Look up port class in scm_port_class.
838 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
839 SCM_INOUT_PCLASS_INDEX): Added.
842 * Makefile.am: Removed genio.c, genio.x.
846 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
848 * init.c: Make sure that scm_post_boot_init_modules is called only
849 once. (Important when using a dumped image.; Thanks to Bernard
852 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
854 * guardians.c (scm_guardian_zombify): Separate scanning for
855 zombies from marking the pairs of the free list.
857 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
858 use the macros. (Thanks to Michael Livshin.)
860 * eval.c (scm_m_lambda): Let bodycheck check the body of the
861 lambda. Let your sins be purified by the blood of the lambda.
862 (Thanks to Eric Hanchrow.)
864 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
865 (Thanks to Valdis Kletnieks.)
867 Fixes for EMX from Mikael Ståldal.
869 * filesys.c: #include <io.h>, if we have it.
870 * scmconfig.h.in: Regenerated.
872 * stime.c (ftime): Delete declaration for this function --- let
873 the system supply it.
875 Cleanups from John Bley.
877 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
879 * gsubr.c: Don't include "gsubr.h" twice.
881 Cleanups for compilation on Irix 6, from David Kaelbling.
883 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
884 regex_t pointer. This is what the callers have, mostly.
885 (scm_regexp_exec): Don't forget to pass the `rx' argument to
886 scm_regexp_error_msg.
888 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
889 int. That way, if we get a warning on this line, it's more likely
890 that we're really missing bits we care about.
892 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
895 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
896 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
897 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
898 cast at all is more appropriate in every case. At the moment, we
899 assume everywhere that SCM is an integral type anyway.
901 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
903 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
904 read_pos after scm_fill_buffer.
906 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
909 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
910 fports.c (fport_fill_buffer): implement the interface change.
912 * ports.c (scm_fill_buffer): interface change: no longer increments
913 read_pos past the character that's returned. it seems clearer to
914 leave it to the caller to decide what to do (thanks Jim).
916 * vports.c (sf_fill_buffer): put the read char into the buffer
917 as well as returning it.
919 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure
922 1999-07-13 Gary Houston <ghouston@easynet.co.uk>
924 * strports.c (scm_strprint_obj): simplify. start with initial
926 (st_seek): don't allow string to be extended if seeking past
927 the end of a read-only port.

931 * strports.c (st_seek): change the resize checks.
933 * ports.c (scm_ftruncate): throw error if offset works out negative.
935 * strports.c (st_flush): increase string size in blocks of
936 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
937 it's greater and reset read_buf_size.
938 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
939 to be maintained for output ports too (it holds the written
940 part of the string, while write_buf may have unwritten buffer
942 (st_truncate): rewritten.
943 (top of file): added a few notes.
945 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
947 Patch from Greg Badros:
948 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
949 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
950 (function pointer) argument to scm_make_gsubr and scm_make_subr
951 calls. This avoids warnings in C++ programs using guile-snarf.
953 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
955 * strports.c (st_grow_port): set pt->read_pos. set
956 pt->read_buf_size one less than pt->write_buf_size if there's
957 an unwritten char at the end of the string. similarly for
959 (st_resize_port): renamed from st_grow_port.
960 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
961 seek from read_end instead of write_end for SEEK_END.
962 (st_ftruncate): calculate current length using readbuf, not write
964 (scm_strport_to_string): use read_buf_size for length.

967 1999-07-05 Gary Houston <ghouston@easynet.co.uk>
969 * strports.c (scm_strport_to_string): new procedure.
970 (scm_call_with_output_string, scm_strprint_obj): use
971 scm_strport_to_string.
972 used SCM_INUM0 instead of SCM_MAKINUM (0) in a few places.
974 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
976 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)
978 Fri Jun 25 22:14:32 1999 Greg Badros <gjb@cs.washington.edu>
980 * smob.c: added scm_make_smob_type_mfpe (), scm_set_smob_mfpe ();
981 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
982 and "bigneg" smob types.
984 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
985 SCM_RETURN_NEWSMOB macro. Added protos for new functions in
988 * *.c: Use scm_make_smob_type_mfpe, instead of scm_newsmob, and
989 use SCM_NEWSMOB or SCM_RETURN_NEWSMOB in constructors instead of
990 SCM_NEWCELL and setting the CAR/CDR by hand.

1014 buffer before calling the ptob routine.
1016 * strports.c (scm_strprint_obj): bug fix: get pt from the port,

1061 * ioext.c (scm_do_read_line): call scm_fill_buffer.
1063 * ports.c (scm_ungetc): don't call SCM_CUNGET. reset the
1064 read buffer pointers.

1074 trinary conditional in order for the flag computation to be
1077 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1079 * struct.c, struct.h:
1081 In order to support different kinds of deallocation, a destructor
1082 slot has been added to struct vtables. This allows for structs
1083 containing pointers to other memory blocks.

1086 instances to this vtable.
1087 (scm_struct_free_0): New destructor: Doesn't deallocate data.
1088 (scm_struct_free_light): New destructor: Deallocates a light
1089 struct (i.e. a struct without hidden slots).

1099 scm_struct_i_size which holds the size of light structs.
1100 (scm_struct_i_n_words): This slot has changed meaning. Previously
1101 it included hidden slots. Now it indicates visible slots.
1102 (scm_alloc_struct): Clear flags.

1152 pointers. (Thanks to Mark Elbrecht.)
1154 1999-06-19 Jim Blandy <jimb@savonarola.red-bean.com>
1156 Patch from Greg Harvey:
1157 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1158 around the condition of an `if', `while', etc., even if the
1159 condition is a macro invocation that expands to something
1160 surrounded by parens. It's more readable.
1162 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1163 proper lists, and of the appropriate lengths.
1164 (check_map_args): New function. (Thanks to Greg Harvey for the
1167 1999-06-19 Michael Livshin <mike@olan.com>

1183 1999-06-16 Jim Blandy <jimb@savonarola.red-bean.com>
1185 * gc.c (scm_mallocated): Just make this signed.
1186 (scm_igc): Check for underflow by seeing if this is negative.
1188 * gc.h (scm_mallocated): Fix declaration.
1189 (Thanks to Greg Harvey.)
1191 * ports.h: #include <sys/types.h>, to get a definition for `off_t'.

1195 * stime.c (bdtime2c): Initialize lt->gmtoff and lt->tm_zone from
1196 sbd_time. (Thanks to Eric Hanchrow.)
1198 Fix from Ken Raeburn <raeburn@raeburn.org>:
1199 * weaks.c (scm_make_weak_vector): Add another extra slot before
1200 vector contents, to be used only during garbage collection.
1201 * weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
1202 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
1204 (scm_weak_size, scm_n_weak): Deleted.
1205 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
1206 vectors without allocating new storage during GC, using
1207 scm_weak_vectors as the head of the chain.
1208 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1209 instead of stepping through an array.
1210 (scm_gc_sweep): Update offset used to find start of weak vector to
1212 (scm_init_storage): Set scm_weak_vectors to EOL.
1214 Fix from Ken Raeburn <raeburn@raeburn.org>:
1215 * gc.c (already_in_gc): New variable.
1216 (scm_igc): Set and clear already_in_gc; abort if it's set at
1219 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
1221 Fix from Gary Houston:
1222 * fports.c (local_seek): Signal an error if the seek fails.
1223 * ports.c (scm_lseek): Don't check return value of port's seek
1224 function; it's its job to signal an error if there's a problem.
1226 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
1228 * strports.c (scm_call_with_output_string): Don't include the

1233 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
1234 scmsigs.c, strports.c, vports.c: Install the sources which
1235 actually correspond to the changes described below. I got the
1236 ChangeLog entries and the patch from two different places...
1238 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1240 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1241 it shows up as terrible performance, as we GC constantly.
1243 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1244 newline. A bit faster, and definitely hairier.
1245 (scm_read_line): Count newlines here instead.
1247 * strings.c (scm_take_str): New function.
1248 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1249 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
1250 scm_take_str, to avoid copying the string.
1252 Add some simple-minded support for line buffered ports.
1253 * ports.h (SCM_BUFLINE): New flag for ports.
1254 * init.c (scm_init_standard_ports): Request line-buffering on
1255 the standard output port.
1256 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1258 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1259 and there's a newline to be written, flush the port.
1261 Gary Houston's open-buffer port patches:
1263 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1265 * ports.c: (scm_lseek): clear buffers even if just reading current
1268 * fports.c (local_fclose): call local_fflush unconditionally.

1271 1999-04-25 Gary Houston <ghouston@easynet.co.uk>
1273 * ports.h (scm_port): make read_pos a pointer to const.
1274 strports.c: take care of rw_active and rw_randow.
1275 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
1276 strports.c (scm_mkstrport): check that pos is reasonable.
1277 ioext.c (scm_ftell, scm_fseek): use lseek.
1278 (SCM_CLEAR_BUFFERS): macro deleted.
1279 ioext.c (redirect_port: use ptob fflush, read_flush.
1280 ports.h (scm_ptobfuns): add ftruncate.
1281 ports.c (scm_newptob): set ftruncate.
1283 ports.c (scm_ftruncate): new procedure.
1284 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
1285 strports.c (st_seek, st_grow_port): new procs.
1286 fports.h (scm_port): change size types from int to off_t.
1287 ports.c (scm_init_ports): initialise the seek symbols here
1288 instead of in ioext.c.
1289 strports.c (scm_call_with_output_string): start with an empty
1290 string, so seek and ftruncate can be used.
1292 gdbint.c: adjust string port usage.
1294 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1296 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1297 equivalent to fflush for the read buffer.
1298 * ports.c (scm_newptob): set read_flush.
1299 ports.c (void_port_ptob): set read_flush.
1300 fports.c (local_read_flush): new proc. add to ptob.
1301 strport.c (st_read_flush): likewise.
1302 vport.c (sf_read_flush): likewise.
1303 fports.h (struct scm_fport): remove random member. there's nothing
1304 left but fdes. leaving it as a struct to allow for future changes.
1305 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1306 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1307 ptob proc if the read buffer is filled.
1309 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1311 * ports.h (scm_port): add a rw_random member and replace
1312 reading and writing members with rw_active member.
1313 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1315 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1317 * ports.h (struct scm_port_table): add writing and reading members
1318 to replace write_needs_seek: it isn't good enough for non-fports.
1319 ports.c, ioext.c, fports.c: corresponding changes.
1320 (struct scm_port_table): give it a typedef and rename to scm_port.
1321 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1322 corresponding changes.
1324 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
1326 * ports.c (scm_newptob): bugfix: set seek member.
1327 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
1328 and generalised to all port types.
1330 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
1332 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1333 signals (it was only being done for handlers installed from Scheme).
1334 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1335 waiting for input caused an EINTR error from read.
1337 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1339 * ports.h (struct scm_port_table): make all the char members
1340 unsigned, so they convert to int without becoming negative if large.
1342 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1344 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1345 with threads enabled. rename this procedure to
1346 fport_wait_for_input and take a port instead of a fdes.
1347 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1349 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1350 get readline support working again: use fdopen to get FILE objects.
1352 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1354 * gc.c (scm_init_storage): install an atexit proc to flush the
1356 (cleanup): the new proc. it sets a global variable which can be
1357 checked by the ptob flush procs to avoid trying to throw
1358 exceptions during exit. not very pleasant but it seems more reliable.
1359 * fports.c (local_fflush): check terminating variable and if set
1360 don't throw exception.
1361 * CHECKME: that the atexit proc is installed if unexec used.
1363 * throw.c (scm_handle_by_message): don't flush all ports here.
1364 it still causes bus errors.
1366 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1367 and move to ioext.c.
1369 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1371 * ports.c (scm_char_ready_p): check the port buffer and call the
1372 ptob entry if needed.
1374 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1375 ptob initialisers. use it in char-ready
1377 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1379 * vports.c (sfflush): modified to write a char (since softports
1380 currently use shortbuf.)
1382 * fports.c (scm_standard_stream_to_port): moved to init.c and
1385 * init.c (scm_init_standard_ports): make stdout and stderr
1386 unbuffered if connected to a terminal. with stdio they
1387 were line-buffered by default.
1389 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1392 * ports.h (scm_ptobfuns): change fflush return to void.
1393 change flush proc definitions.
1395 * strports.c (scm_call_with_output_string): get size from
1396 buffer instead of port stream.
1397 (st_flush): new proc.
1399 * ports.h (struct scm_port_table): added write_end member,
1400 as an optimisation. set it where write_buf_size is set.
1402 * ports.h (struct scm_port_table): change stream from void *
1403 back to SCM. SCM presumably must be large enough to hold a
1404 pointer (and probably vice versa but who knows.)
1405 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1407 (scm_puts): rewritten
1408 * fports.c (local_ffwrite, local_fputs): removed.
1409 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)
1410 * vports.c (sfputc, sfputs, sfwrite) likewise.
1411 * ports.c (write_void_port, puts_void_port): removed.
1412 (putc_void_port, getc_void_port, fgets_void_port): likewise.
1414 * ports.c (scm_lfwrite): rewritten using fport.c version.
1416 * fports.c (local_fputc): deleted.
1418 * ports.c (scm_add_to_port_table): initialise write_needs_seek.
1420 * ports.h (scm_ptobfuns): add seek function pointer.
1421 * fports.c: set it to local_seek, new procedure.
1424 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1425 use ptob for seek. take ptob instead of fport arg.
1427 * ports.h (struct scm_port_table): new member write_needs_seek,
1428 replaces reading member in fport struct.
1430 * vports.c (sfgetc): store the getted char into the buffer.
1431 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1432 the Scheme interface is still a procedure that gets a char.
1433 (scm_make_soft_port): set up the port buffer (shortbuf).
1435 * fports.c (local_fgetc, local_fgets): deleted.
1436 * strports.c (stgetc): likewise.
1437 * ports.c: scm_generic_fgets: likewise.
1439 * ports.h (scm_ptobfuns): add fill_buffer.
1440 * ports.c (scm_newptob): assign it.
1441 * strports.c (scm_mkstrport): set up the buffer.
1442 put just the string into the stream, not cons (pos stream).
1443 (stfill_buffer): new proc.
1445 * ports.h: fport buffer moved into port table: to be
1446 used for all port types.

1455 scm_getpeername, scm_recv, scm_send, scm_recvfrom,
1457 use SCM_FPORT_FDES. use SCM_OPFPORTP not SCM_FPORTP.
1459 * posix.c (scm_getgroups): use SCM_ALLOW/DEFER_INTS.
1460 (scm_ttyname): use SCM_FPORT_FDES.

1485 derive buffer size from fdes or use a default.
1486 (scm_fdes_to_port): use setvbuf instead of creating the buffers
1489 vports.c (various places): use SCM_SSTREAM.

1491 * gdbint.c: likewise.
1492 * ports.h (SCM_SSTREAM): new macro.
1494 * fports.c (scm_input_waiting_p): use scm_return_first, since port

1497 * fports.h (SCM_CLEAR_BUFFERS): new macro.
1499 * filesys.c (scm_fsync): use SCM_FDES.
1501 * ports.c (scm_force_output): call scm_fflush.

1517 ports.c fports.c ioext.c posix.c socket.c net_db.c filesys.c:
1518 removed all uses of SCM_DEFER/ALLOW ints for now. they were mainly
1519 just protecting errno. some may need to be put back.
1521 * scmsigs.c (take_signal): save and restore errno while this
1524 *fports.c (print_pipe_port, local_pclose, scm_pipob): deleted.
1525 open-pipe, close-pipe are emulated in (ice-9 popen)

1645 * strop.c (scm_substring_move_x): New function, which can handle
1646 arbitrary overlapping substrings.

1721 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1723 * numbers.c (isfinite): Define this macro if not defined: Return a
1724 non-zero value if X is finite. (From ISO C 9x standard.)

1753 (scm_system_module_env_p): Assume root environment is no lookup
1756 * debug.c, eval.c, evalext.c, gdbint.c stacks.c:

1777 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1779 Most of this batch of changes is about how to deal with extended
1780 types when an object system is loaded into Guile. A nice object
1781 system is capable of representing Guile's types as class objects.
1783 For example, we want a regular expression to be of class <regex>.
1784 But regular expressions are smobs which aren't under direct
1785 control of the object system, so there has to be some mechanism
1786 which informs the object system that a new class should be created
1787 which can represent the smob type. I call this a "wrapper class".
1789 * objects.c: #include "smob.h";
1790 (scm_class_keyword): Removed. (Class is automatically created by
1792 (scm_smob_class): Array of smob classes indexed by smobnum.
1793 (scm_make_extended_class): "Plugin" function pointer for creation
1794 of wrapper classes for smob and struct types.
1795 (scm_class_of): Handle compiled closures. (Currently regarded as
1797 Use scm_smob_class to handle smob types;
1798 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1799 through scm_smob_class;
1802 * smob.c (scm_newsmob): Also create a wrapper class if
1803 scm_smob_class has been initialized.
1805 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1806 type code and smobnum.
1808 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1809 (scm_struct_table): Weak key table with auxilliary information for
1810 struct types. Currently used for names and wrapper classes.
1811 (scm_struct_ihashq): Hash function for structs.
1812 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1813 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1814 for accessing names of vtables. The record implementation in
1815 boot-9.scm currently uses the setter to record the name of record
1816 types. When the object system is initialized, it can use this
1817 information to create wrapper classes with suitable names.
1818 (scm_init_struct): Allocate scm_struct_table.
1819 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1820 (struct tags are a finite resource and we might want to restrict
1821 the use of tags to vtables only. E.g., Goops only uses tags for
1823 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1825 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1828 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1829 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1830 Used for access of struct table entries.
1832 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1833 (scm_hash_fold): New procedure. Used to process all entries in a
1834 hash table (in no particular order).
1836 Argh! For the umpteenth time I got compilation errors because of
1837 the "intuitive" name `kw'. This has to have an end:
1839 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1840 "kw" --> "keywords" everywhere.
1841 (I doubt that this will cause big compatibility problems since the
1842 application interface is unaffected.)
1844 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1846 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1848 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1849 column inums to native form.
1851 Improvement of backtraces: Introduces a new stack narrowing
1852 specifier, #t, for the inner cut. (See further in the comments in
1853 stacks.c:narrow_stack ().)
1855 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
1856 (Used to flag certain system procedures which shouldn't turn up in
1859 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1860 modules which aren't "user" modules and the code of which
1861 shouldn't turn up in backtraces.)

1864 Extract the lookup closure from an environment.
1865 (scm_system_module_env_p): New function: Return non-#f if MODULE
1868 * stacks.c: #include "eval.h"; #include "procprop.h";

1871 * debug.c (scm_procedure_name): Use name property in the default
1874 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1876 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1878 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1879 procedure throughout.
1881 * print.c (scm_iprin1): Removed extraneous space when printing
1882 procedure-with-setters.
1884 Entity and operator setter slots were introduced as a complement
1885 to the <procedure-with-setter> type in order to support entities
1886 and operators with setters in a reasonable and efficient way.
1887 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1890 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1902 * objects.h (SCM_OBJ_CLASS_REDEF): New macro: Find class slots
1903 directly through the instance.
1905 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1907 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1908 scm_struct_i_flags instead of scm_vtable_index_layout!
1910 * list.c (scm_list_star): New procedure.
1912 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1914 * debug.c (scm_init_debug): Added scheme level constant

1992 sysdep_dynl_unlink, sysdep_dynl_func): Arguments FNAME, SUBR, and
1993 SYMB now point to const.
1995 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1997 * print.c (scm_iprin1): Use scm_procedure_name instead of
1998 scm_procedure_property for compiled closures.
2000 * tags.h (scm_tc7_pws): New procedure type. Four representations
2001 for procedure-with-setters were considered before selecting this
2004 1. A closure where the CODE and ENV slots are used to represent
2005 the getter and a new SETTER slot is used for the setter. The
2006 original getter is stored as a `getter' procedure property. For
2007 closure getters, the CODE and ENV slots contains a copy of the
2008 getter's CODE and ENV slots. For subr getters, the CODE contains
2011 2. A compiled closure with a call to the getter in the cclo
2012 procedure. The getter and setter are stored in slots 1 and 2.
2014 3. An entity (i.e. a struct with an associated procedure) with a
2015 call to the getter in the entity procedure and the setter stored
2016 in slot 0. The original getter is stored in slot 1.
2018 4. A new primitive procedure type supported in the evaluator. The
2019 getter and setter are stored in a GETTER and SETTER slot. A call
2020 to this procedure type results in a retrieval of the getter and a
2021 jump back to the correct eval dispatcher.
2023 Representation 4 was selected because of efficiency and
2026 Rep 1 has the advantage that there is zero penalty for closure
2027 getters, but primitive getters will get considerable overhead
2028 because the procedure-with-getter will be a closure which calls
2031 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
2032 <procedure-with-setter>, but together with rep 2 it suffers from a
2033 three level dispatch for non-GOOPS getters:
2035 cclo/struct --> dispatch proc --> getter
2037 This is because the dispatch procedure must take an extra initial
2038 argument (cclo for rep 2, struct for rep 3).
2040 Rep 4 has the single disadvantage that it uses up one tc7 type
2041 code, but the plan for uniform vectors will very likely free tc7
2042 codes, so this is probably no big problem. Also note that the
2043 GETTER and SETTER slots can live directly on the heap, using the
2044 new four-word cells.
2046 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,
2047 SCM_SETTER): New macros.

2077 Renamed scm_i_set_x --> scm_sym_set_x and made global.
2078 Renamed s_set_x --> scm_s_set_x and made global.
2080 1999-01-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2082 * random.c (scm_i_random_bignum): Made independent of endianness.

2100 scm_rstate from seed.
2101 (scm_copy_random_state, scm_seed_to_random_state): New functions.
2102 (scm_make_random_state): Removed.
2104 * random.c (scm_make_random_state): Use scm_i_make_rstate().
2106 1999-01-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2108 * random.c: Bugfix: Retrieve and store most significant 32 bits in
2109 different order if the machine is bigendian.

2112 1999-01-11 Roland Orre <mdj@mdj.nada.kth.se>
2114 * sort.c (scm_merge, scm_merge_list_x): Bugfix: Place elements
2115 from first arg before equal elements in second arg in result.
2116 (scm_merge_list_step): Bugfix: Don't presume that arguments in a C
2117 function call are executed in a well defined order.
2119 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2121 * alloca.c (alloca): Cast value returned by malloc. (Thanks to
2124 1999-01-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2126 * random.c: Removed alloca includes.
2128 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2130 * Makefile.in: This changed, for some reason I don't really
2131 understand, when I ran automake in the top level directory. This
2132 may be contamination by Cygnus internal releases. If you re-run
2133 automake and this change gets reverted, don't worry about it.
2135 1999-01-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2137 * sort.c, sort.h: New files: Implement slib's and scsh's sort

2150 * random.c, random.h: New files: Random number support.
2151 Interface same as slib's.
2153 * Makefile.am: Added random.c, random.h, random.x.
2155 * init.c: #include "random.h";

2158 1998-12-23 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2160 * Makefile.am: New files: guardians.c, guardians.x, guardians.h
2162 * guardians.c, guardians.h (scm_make_guardian,
2163 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
2164 scm_get_one_zombie, scm_init_guardian): This is an implementation
2165 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
2166 David Eby (1993) "Guardians in a Generation-Based Garbage
2167 Collector" ACM SIGPLAN Conference on Programming Language Design
2168 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
2169 /pub/scheme-repository/doc/pubs/guardians.ps.gz
2170 Author: Michael N. Livshin.
2172 * gc.h (SCM_MARKEDP, SCM_NMARKEDP): New macros.
2174 * gc.c (scm_igc): Call scm_guardian_gc_init and
2175 scm_guardian_zombify.

2179 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2181 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
2184 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2186 Move the procedure slots of entities to invisible slots (so that
2187 we can have operator class objects which themselves are entities).
2188 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
2189 SCM_STRUCTF_ENTITY): New constants.
2191 * struct.c (scm_make_struct): Allocate "invisible" room for
2192 procedures if SCM_STRUCTF_ENTITY is set in vtable.
2194 * gc.c (scm_gc_mark): Mark entity procedures.

2201 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
2202 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
2204 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
2206 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
2207 of syntactic forms, similar to SCM_PROC.
2208 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
2209 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
2210 for the name symbols when needed.
2212 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
2214 * Makefile.in: Regenerated.
2216 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
2218 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
2219 take the address of _into; it might be a register. Just have
2220 scm_debug_newcell return the new cell.
2221 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2222 taking the address of a place to store it as an argument.
2223 * gc.h (scm_debug_newcell): Change declaration.
2224 (Thanks to Greg Harvey.)
2226 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2228 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
2229 Replaces old names serial-array-copy! and serial-array-map!.

2235 * smob.c (freeprint): New function.
2236 (freecell): Use it to print freed objects, for slightly easier
2239 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2241 * backtrace.c (display_frame): Made more robust. Doesn't throw an
2242 error if no source properties can be found for a frame. (Thanks
2243 to Christian Lynbech.)
2245 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2247 * objects.h: Removed slots direct_supers and direct_slots from the
2248 definitions of the rudimentary classes described by objects.h.
2250 * objects.c, objects.h (scm_entity_p): New procedure. Together
2251 with the predicates scm_procedure_p and scm_struct_p, this
2252 predicate makes it possible to differ between structs, entities
2255 * modules.c, modules.h (scm_resolve_module): New function.
2257 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2259 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2260 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2263 * objects.c (scm_entity_p): New procedure.
2265 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
2266 for asubrs, rpsubrs, lsubrs and lsubr_2s.
2268 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2270 * procprop.h (scm_i_procedure_arity): Added declaration.
2272 * procprop.c (scm_i_procedure_arity): Made global; New code to
2273 handle operators and entities.
2274 (scm_procedure_property): No need to call scm_procedure_p since
2275 scm_i_procedure_arity now does all necessary type checking.
2276 Added #include "objects.h".
2278 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2279 s_add_hook_x --> s_remove_hook_x.
2280 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
2281 Added #include "procprop.h"
2283 * feature.c, feature.h (scm_reset_hook_x): New procedure.
2284 (scm_make_hook): Optional argument defines number of arguments to
2286 (scm_make_named_hook): Take number of args as second arg.
2287 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2288 boot-9.scm for a while); First arg is the hook. The rest are
2289 arguments passed on to the hook procedures.
2291 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2293 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2294 scm_logbit_p): Do the computation in ulongs. This is not as nice
2295 as doing it in bignums, but at least it's good enough for
2296 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2298 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2299 subexpressions. (Thanks to Charbel Jacquin.)
2301 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2303 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2304 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2305 (scm_make_named_hook): New function.
2307 * feature.c: Added #include "eval.h".
2309 * modules.c (scm_make_module): Beautify the module.
2311 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2313 * modules.c, modules.h: New files: C interface to modules. (This
2314 is necessary in order to interface the object system to Guile
2315 properly. The guts of these modules will be replaced by the new
2316 module system in the future.)
2318 * init.c: Added #include "modules.h"
2319 (scm_boot_guile_1): Call scm_init_modules.
2320 (invoke_main_func): Call scm_post_boot_init_modules.
2322 * Makefile.am: Added modules.c, modules.x, modules.h.
2324 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2326 * procs.c: #include "objects.h"
2327 (scm_procedure_p): Return #t also on structs which are operators.
2329 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2330 <operator-metaclass> and <entity-class> to <standard-class>,
2331 <operator-class> and <entity> in order to conform with STKlos
2334 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2335 which isn't an operator.
2336 (SCM_APPLY): Ditto, but jump to badproc.
2338 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2340 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2341 Previously, structs implanted in code were interpreted as forms
2342 the operator of which was a gloc. We solve this by checking for
2343 the zero in the emulated vcell in the struct vtable. Since
2344 implanted structs always will look like forms with a gloc
2345 operator, execution will only be slowed down by maximally one
2346 extra test-and-branch per application.
2348 * evalext.c (scm_definedp): Removed check for isyms; Added a
2349 second optional argument: It is now possible to supply an
2350 evaluation environment in which to look for the symbol.
2352 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2354 * readline.c (scm_init_readline): Set
2355 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2357 * coop.c (coop_condition_variable_wait): Removed
2358 (coop_condition_variable_wait_mutex): Folded logic of
2359 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2360 prevent condvar signal lossage. Previously, another thread could
2361 start to run after unlocking the mutex but before putting the
2362 current thread on the wait queue. If that thread then would
2363 signal the first, the signal would be lost. (Thanks to Christian
2366 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2368 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2371 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2373 * objects.c (scm_i_make_class_object): Renamed from
2374 make_class_object; exported; error checking moved to
2375 scm_make_class_object and scm_make_subclass_object.
2376 (scm_make_class_object, scm_make_subclass_object): Use
2377 scm_i_make_class_object.
2378 (scm_make_subclass_object): Let the subclass have same metaclass
2381 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2383 * debug.c (scm_debug_options): Bugfix: Set the value of
2384 scm_stack_checking_enabled_p after setting debug options;
2385 #include "stackchk.h". (Thanks to Richard Polton.)
2387 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2389 * unif.c (scm_array_contents): removed unnecessary test for 0
2392 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2394 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2395 Replaced by macro `collect' in boot-9.scm.
2397 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2399 * eval.c (scm_copy_tree): Copy source properties if existent.
2401 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2402 don't, we may end up passing memoized source to a transformer.)
2404 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2406 * stack.c (get_applybody): Help function which lookups the first
2407 body form of the apply closure.
2408 (read_frames): Prevent the source of the first form of the apply
2409 closure from being recorded. This would only be confusing.
2411 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2412 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2414 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2416 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2418 (read_frames): Use SCM_MACROEXPP.
2420 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2422 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2423 don't contain interesting information since all arguments are
2424 present in the frame which applies the compiled closure anyway.);
2425 Skip the transformer application frames.
2427 * print.c (scm_iprin1): Print gsubrs as primitives.
2429 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2431 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2433 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2434 that we can identify these in a backtrace. (This change doesn't
2435 introduce any significant speed penalty.)
2437 * eval.c: Added note about `serial-map' using scm_map.
2439 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2440 readline options. They should reside in their own options array.
2442 * readline.c, readline.h (scm_readline_options,
2443 scm_readline_opts): Moved readline options here.
2445 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2447 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2448 SCM_ROCHARS instead of SCM_CHARS.
2450 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2451 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2453 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2455 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2456 This is quite important since the latter clears the
2457 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2458 every single character read...
2460 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2462 * print.c (scm_iprin1): Removed suspect looking (and indeed
2463 malevolent) semicolon after test for user supplied closure print
2464 procedure. (Thanks to Telford Tendys.)
2466 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2467 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2468 starting to search the list. Removed call to sloppy_mem_check.
2470 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2471 procedures: Same as scm_delq_x et al, but delete maximally one
2474 * options.c (scm_options, scm_init_options): GC-protect option
2475 values of type SCM. (Thanks to Telford Tendys.)
2477 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2479 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2480 make sure that there always is a "real" scm_lookupcar.
2482 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2484 * read.c, read.h (scm_read_opts): New read options
2485 "history-length" and "history-file".
2486 (scm_read_options): Stifle history to history length.
2488 * readline.c (scm_read_history, scm_write_history): New procedures.
2490 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2492 * eval.h (scm_macro_eval_x): Removed declaration.
2494 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2495 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2496 Renamed and made global.
2498 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2499 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2501 * evalext.c, evalext.h: New files. Contain non-R5RS things
2502 having to do with evaluation.
2504 * evalext.c (scm_serial_map): New procedure: Version of `map'
2505 which guarantees that the procedure is applied to the lists in
2507 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2508 returns a list of the results of the body forms instead of the
2509 result of the last body form.
2510 (scm_definedp, scm_m_undefine): Moved from eval.c
2512 * evalext.h (scm_m_sequence_to_list): Added declaration.
2514 * macros.c, macros.h: New files.
2515 (scm_procedure_to_syntax, scm_procedure_to_macro,
2516 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2517 scm_macro_name, scm_macro_transformer): Moved from eval.c
2518 (scm_make_synt): Moved from eval.c
2520 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2522 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2525 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2527 * debug.c, print.c: Added #include "macros.h".
2529 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2531 This change adds the ability to use `unread-char' multiple times
2532 without interspersed reads and adds the new procedure
2533 `unread-string'. The change is optimized for the common case of
2534 unreading a single character. This is also the reason behind the
2535 choice to store characters in the port itself: in most cases no
2536 extra malloc is required.
2538 The amount of code in some macros in ports.h has been increased to
2539 the extent that they would fit better as C functions, but, since
2540 this code belongs to the port representation, such functions
2541 should be placed in ports.c which would cause calls back and forth
2542 between ports.c and genio.c. That is not good for performance.
2543 Also, keeping them as macros allows the compiler to do some
2544 optimizations which are needed to make the current interface
2545 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2547 One benchmark (Guile startup time) indicates an increase of
2548 loading speed of 1%. Another (reading (using `read') boot-9.scm
2549 10 times) shows no change in performance.
2551 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2552 made to find a beautiful solution.)
2554 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2555 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2556 character. (SCM_CLRDY clears all.)
2557 (SCM_N_READY_CHARS): New macro: Returns number of unread
2558 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2559 (struct scm_port_table): New fields: `entry' contains port table
2560 index, `cp' points to last unread char, `cbuf' is the buffer for
2561 unread chars, `cbufend' points after end of the character buffer.
2563 * ports.h, ports.c (scm_unread_string): New procedure.
2564 (scm_grow_port_cbuf): New function.
2566 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2568 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2569 to read unread characters. Use SCM_TRY_CLRDY instead of
2572 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2574 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2576 * genio.c, genio.h (scm_ungets): New function.
2578 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2581 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2583 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2584 declarations. (Thanks to Russ McManus.)
2586 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2588 * numbers.c (num2long): As a software archeologist, I'm proud of
2589 this finding! :) Preliminary dating suggests an almost 4 year old
2590 remnant from the SCM ancestor. The sample has been removed from
2591 the finding site and is now safely stored in the repository.
2593 * numbers.h: Removed prototype for num2long.
2595 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2597 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2598 array as second arg.
2599 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2600 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2601 * gh.h: Updated and added prototypes.
2603 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2605 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2607 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2609 * guile-snarf.in: Never generate an empty file. (Thanks to
2612 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2613 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2614 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2615 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2616 gh_new_procedure5_0): Specify argument types, to appease C++
2617 compilers. (Thanks to Brad Bowman.)
2619 Bug reports from Russ McManus:
2620 * guile-snarf.in: If the CPP environment variable is set, use that
2621 as the C preprocessor, instead of the preprocessor autoconf
2623 * snarf.h (SCM_PROC): Cast the function pointer passed to
2624 scm_make_gsubr, to satisfy C++.
2626 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2627 Use the handler passed, instead of ignoring it and using
2628 gh_standard_handler. (Thanks to Etienne Bernard.)
2630 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2632 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2635 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

2652 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2655 * script.c (scm_compile_shell_switches): Define
2656 use-emacs-interface in the root module, so the repl code can see
2657 it. See today's change to top-repl in ice-9/boot-9.scm.
2659 * filesys.c (set_element, get_element): Make sure that `element'
2660 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2661 Boekemeier and Jorgen "forcer" Schaefer.)
2663 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2665 * chars.c (scm_charnames): In ASCII character name table, make
2666 newlines print as #\newline by default, not #\nl.
2668 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2669 alphabetical order. Oh thrills. But it helps me know how far
2670 along in the compilation I am.
2671 * Makefile.in: Regenerated.
2673 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2675 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2676 #bytes(...) to #y(...), and syntax for short vectors from
2677 #short(...) to #h(...). This may seem nutty, but, like the other
2678 uniform vectors, byte vectors and short vectors want to have the
2679 same print and read syntax (and, more basic, want to have read
2680 syntax!). Changing the read syntax to use multiple characters
2681 after the hash sign breaks with the conventions used in R5RS and
2682 the conventions used for the other uniform vectors. It also
2683 introduces complexity in the current reader, both on the C and
2684 Scheme levels. (The Right solution is probably to change the
2685 syntax and prototypes for uniform vectors entirely.)
2687 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2689 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2690 (Thanks to Jorgen "forcer" Schaefer.)
2691 * ports.h (SCM_NOFTELL): New flag.
2692 * fports.c (local_fgets): If it's set, use the generic fgets.
2693 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2695 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2697 * script.c (scm_compile_shell_switches): Add handling of -q switch
2698 (inhibit loading of user init file).
2699 (scm_shell_usage): Add usage text for -q switch.
2700 (scm_compile_shell_switches): Always load user init file first if
2701 it is loaded at all.
2703 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2705 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2706 and is now broken under NetBSD. I can't fathom what it's trying
2707 to do, so I've replaced it with something that I do understand,
2708 which seems to work, and which isn't broken on NetBSD. "Progress?
2709 You Decide." (Thanks to Perry Metzger.)
2711 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2712 signed/unsigned comparison.
2714 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2716 Warning fixes from Greg Harvey:
2717 * unif.c (scm_array_set_x): initializer for pos
2718 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2719 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2720 initializers for field_type, since EGCS so desparately wants to
2722 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2723 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2724 when GUILE_DEBUG is defined.
2725 * dynwind.h (scm_wind_chain): Same.
2726 * ports.h (scm_pt_size, scm_pt_member): Same.
2727 * print.h (scm_current_pstate): Same.
2728 * procs.h (scm_make_cclo): Same.
2730 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2732 Handle short and long long uniform arrays properly. (Thanks to
2734 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2735 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2736 scm_tc7_llvect (long long vectors).
2738 Change the way libguile and boot-9.scm are timestamped, to try to
2739 get rid of these spurious mismatch warnings. Now both
2740 libguile/versiondat.h and ice-9/version.scm are generated directly
2741 by the configuration process, rather than having version.scm
2742 generated directly, and libguile/versiondat.h generated by the
2743 Makefile, which is generated by configure. It seems that
2744 sometimes the Makefile would change, but versiondat.h depends on
2745 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2746 * Makefile.am (versiondat.h): Target removed; this is generated
2747 directly by the configure script now.
2748 (BUILT_SOURCES): Remove versiondat.h.
2749 * versiondat.h.in: New file, transformed by the configure script
2751 * Makefile.in: Regenerated.
2753 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2754 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2755 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2756 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2757 if we want to use them in a header file some day, we can. (Thanks
2758 to Michael Livshin.)
2760 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2761 SCM numbers, so we won't have rollover problems; the range of a
2762 signed long in milliseconds is about 25 days. (Thanks to Karl
2765 Don't redefine sleep and usleep; fix this problem now.
2766 * coop.c (sleep, usleep): Remove declarations; we don't use or
2767 redefine these any more.
2768 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2769 job of usleep and sleep in a thread-friendly way. We can use
2770 these in the rest of Guile. Define versions for systems both with
2771 and without iselect.
2772 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2773 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2774 we're just using it, not redefining it, we can use a K&R style
2776 (sleep): Declare this, too, if the system hasn't.
2777 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2778 scm_uthread_sleep if they're available; otherwise, just call the
2780 * scmconfig.h.in: Regenerated.
2782 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2784 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2786 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2788 * threads.c: Doc fix.
2790 The argument type of usleep varies from system to system,
2791 as does the return type. We really shouldn't be redefining usleep
2792 at all, but I don't have time to clean that up before the 1.3.
2793 release. It's on the schedule for afterwards. (Thanks to Julian
2795 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2797 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2798 * scmconfig.h: Regenerated.
2800 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2801 right way to handle system variation. Autoconf's approach is the
2803 * simpos.h (scm_software_type): Declaration deleted.
2805 * script.c (scm_find_executable): Don't test if unix is #defined
2806 here; first, NetBSD doesn't #define it, and second, it's the wrong
2807 way to go about these things. (Thanks to Perry Metzger.)
2808 (dld_find_executable): Delete this MSDOS support code. This isn't
2809 the way we want to support this; it needs to be rethunk at a
2812 * genio.c (scm_do_read_line): Don't just politely check that the
2813 line was either non-empty or EOF. Abort if it's empty and not
2816 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2818 * scmconfig.h.in: Regenerated.
2820 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2823 * genio.c (scm_do_read_line): Count lines correctly when the file
2824 doesn't end in a newline.
2826 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2828 * genio.c (scm_do_read_line): Maintain the line count correctly.
2829 (Thanks to Harvey J. Stein and Greg Harvey.)
2831 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2834 * numbers.c (big2str): Protect t from garbage collection until
2835 we're done. (Thanks to Gary Houston.)
2837 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2839 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2841 * Makefile.in: Regenerated.
2843 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2844 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2847 Do magic to mix reads and writes on stdio FILE-based ports.
2848 (Thanks to Christian Lynbech.)
2849 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2851 (pre_read, pre_write): New functions.
2852 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2853 local_fputs): Call them.
2854 (local_fflush): Mark the port as ready for reading and writing.
2855 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2856 flags on new port objects. This might not be accurate --- who
2857 knows what state the FILE * is in when we get it --- but it won't
2858 do extraneous calls to fflush or fseek, so it's no worse than the
2859 behavior before this change.
2860 * ports.h: Add comment.
2862 Centralize the creation of port objects based on stdio FILE * in
2863 fports.c; don't just throw them together anywhere.
2864 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2865 what the rest of Guile wants. Don't set the revealed count;
2866 that's only appropriate for stdin, stdout, stderr.
2867 (scm_standard_stream_to_port): This function does set the revealed
2869 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2870 not scm_stdio_to_port.
2871 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2872 * fports.c (scm_open_file): Same.
2873 * posix.c (scm_pipe): Same.
2874 * socket.c (scm_sock_fd_to_port): Same.
2875 * ioext.c (scm_fdopen): Same.
2876 (scm_freopen): Moved from here to...
2877 * fports.c (scm_freopen): ... here. This is really something that
2878 munges the internals of an fport, so it should go here.
2879 * fports.h (scm_stdio_to_port): Adjust prototype.
2880 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2881 * ioext.h (scm_freopen): Prototype removed.
2883 * filesys.c (set_element, get_element): This can work on both pipe
2884 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2887 * scmconfig.h.in: Regenerated.
2889 Change the definition of the functions in scm_ptobfuns so that
2890 they get passed the port object, not the port's stream.
2891 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2892 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2893 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2894 Pass the port itself to the scm_ptobs function.
2895 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2896 scm_generic_fgets): Same.
2897 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2898 getc_void_port, fgets_void_port, close_void_port): Just change the
2899 argument names; these functions don't really do anything.
2900 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2901 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2902 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2903 Also, use prototyped definitions, and get rid of the extra
2905 (scm_fptob, scm_pipob): We don't need casts here any more.
2906 * strports.c (prinstpt): Use prototype declarations.
2907 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2908 and use SCM_STREAM to get the string info. Also, use prototyped
2909 definitions, and get rid of the extra declarations.
2910 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2913 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2914 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2916 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2917 scm_fgets, for consistency.
2918 (scm_fptop, scm_pipob): References updated.
2920 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2922 Include the source location in error messages for scripts.
2923 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2924 stack is still there when we catch the error.
2925 * throw.c (handler_message): If we are handling an error with a
2926 message, then put together the proper arguments and call
2927 scm_display_error, instead of scm_display_error_message. That
2928 displays source location, if it can find it.
2930 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2932 * gc.c (scm_unprotect_object): Change this so that calls to
2933 scm_protect_object and scm_unprotect_object nest properly.
2934 (scm_protect_object): Doc fixes.
2936 * strings.c (scm_string_set_x): Require the argument to be a
2937 writable string, not a substring or a symbol.
2938 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2939 (Thanks to John Redford and Charbel Jacquin.)
2941 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2943 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2945 * eval.c (safe_setjmp): Remove this misunderstanding.
2946 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2949 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2951 * libguile.h: Mark these as C declarations, for compilation by C++
2954 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2955 __cplusplus clause. I seriously doubt this ever worked the way
2956 the author seems to have intended.
2958 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2960 Utterly needless cleanups to hopelessly messy code.
2961 * ports.c: Doc fixes.
2962 (scm_fflush): Moved to ...
2963 * genio.c (scm_fflush): ... here, amongst all the other port
2964 method invocation functions.
2965 * genio.h, ports.h: The prototype moves too.
2967 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2969 * backtrace.c (display_error_body): The current frame does not
2970 always have a parent frame; consider a function called directly
2971 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2974 * alloca.c (alloca): Undo yesterday's changes, and simply call
2975 malloc directly for storage, and abort if we don't get what we
2976 want. The situation is much simpler --- just call malloc. Emacs
2977 has bizarre/evil requirements (signal handlers might malloc unless
2978 you set this global flag, so you have to set the flag around all
2979 calls to malloc) which we are certainly not going to conform to,
2980 so we can do the simple and obvious thing.
2982 * coop.c (coop_condition_variable_wait): Make this function
2983 static. It's only useful internally --- you should never just
2984 wait on a condition variable.
2985 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2987 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2989 * unif.c (scm_array_set_x): Accept any kind of number as an
2990 element for a uniform vector of doubles. This is more consistent
2991 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2993 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2994 works; I can't conveniently test it myself. (Thanks to Dvid
2995 Tillman for the bug report.)
2997 * init.c: Doc fixes.
2999 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
3000 from here, not from scm_compile_shell_switches (which is a pretty
3001 dumb place to do it).
3002 (scm_load_startup_files): New function.
3003 (scm_ice_9_already_loaded): Variable moved to here from script.c.
3004 * script.c (scm_compile_shell_switches): Don't load the startup
3006 (scm_ice_9_already_loaded): Variable moved.
3007 * init.c (scm_load_startup_files): Prototype for new function.
3008 * gh_init.c (gh_enter): Doc fix.
3010 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3012 Some anti-warning changes from Greg Harvey.
3013 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
3014 warnings when it doesn't understand our NORETURN declarations in
3016 * posix.c (scm_mknod): Similar.
3018 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3020 * posix.c (scm_getpwuid): If we can't find an entry, return our
3021 own message, instead of using scm_syserror --- the getpwMUMBLE
3022 functions don't set `errno' to anything interesting.
3024 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3026 Get rid of warnings from the cooperative threading system.
3027 * threads.h (scm_single_thread_p, scm_yield,
3028 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
3029 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
3030 scm_wait_condition_variable, scm_signal_condition_variable): Add
3031 prototypes for these Scheme-visible functions.
3032 * coop-defs.h (coop_next_runnable_thread,
3033 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
3034 Prototypes for these here, even though they're from iselect.c.
3035 (coop_condition_variable_wait, coop_join): Add prototypes.
3036 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
3037 scm_threads_free_condvar): Make these smob functions static.
3038 * coop-threads.h (coop_init): Give this a real prototype.
3039 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
3040 (coop_next_runnable_thread): No need to provide prototype; it's in
3043 * scmconfig.h.in: .detarenegeR
3045 * iselect.c, threads.c: Doc fixes.
3047 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3049 * Makefile.in: Regenerated with a patched automake, to get
3050 dependency generation right when using EGCS.
3052 * inet_aton.c (inet_aton): Add prototype, to remove compiler
3053 warning. (Thanks to Robert Pluim.)
3055 * inet_aton.c (inet_aton): Reassure the compiler that the
3056 arguments to the <ctype.h> macros are all unsigned characters, not
3059 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3061 Getting rid of more warnings...
3062 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
3063 today's change to ../configure.in.
3064 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
3065 * scmconfig.h.in: Regenertaded.de.,.__
3066 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
3067 (scm_localtime, scm_mktime): Use a const char * to manipulate the
3070 * readline.c: Doc fix.
3071 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
3072 * readline.h (scm_filename_completion_function): Add prototype.
3073 (scm_init_readline): Make this into a prototype.
3075 * readline.c (scm_filename_completion_function): Use SCM_PROC to
3076 declare this, instead of calling scm_make_subr manually.
3078 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
3080 * readline.h (scm_init_readline): Add prototype for this.
3081 (scm_init_readline): Make this a real prototype.
3083 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3085 Warning fixes from Maciej Stachowiak:
3086 * backtrace.h (scm_display_application, scm_backtrace): Add
3088 * debug.c (scm_m_start_stack): Make this function static.
3089 * fluids.h (scm_fluid_p): Add prototype.
3090 * procprop.c (scm_i_procedure_arity): Make this function static.
3091 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3092 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
3093 * root.h (scm_dynamic_root): Add external prototype.
3094 * scmsigs.h (scm_usleep): Add external prototype.
3095 * script.h (scm_init_script): Use prototype, not K&R decl.
3096 * stacks.h (scm_stack_id): Add external prototype.
3097 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3099 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3101 * gh.h: took out the definitions of vset and vref, since they are
3102 replaced by the proper vector routines that correspond to the R4RS
3105 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3107 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3108 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3109 third argument, a C expression that should result in a SCM value,
3110 which is used to initialize the variable. Reimplemented
3111 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3114 * version.h (scm_libguile_config_stamp): Add prototype.
3115 (From Maciej Stachowiak.)
3117 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3119 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3120 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3122 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3124 * print.c (scm_iprin1): Rather than having one i, and using it in
3125 several places, declare a fresh i local to each block where it is
3126 used, and give it a signedness appropriate to its use in each case.
3127 (scm_iprlist): Same.
3129 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3130 comparison warnings.
3132 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3133 signed/unsigned clashes.
3135 * posix.h (scm_tmpnam): Added prototype.
3137 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3138 scm_make_subclass_object): Add external prototypes.
3140 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3141 comparison is okay here.
3143 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3145 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3146 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3148 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3151 * load.c (swap_port): Make this function static.
3153 * load.c (scm_search_path): Make max_path_len and max_ext_len
3154 unsigned, since they're compared against string sizes.
3156 * load.c (init_build_info): Make i unsigned.
3158 * ioext.h (scm_read_line): Add prototype.
3160 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3161 scm_hash_fn_remove_x): Make hash bucket index local variable k
3162 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3163 accurately as possible.
3165 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3166 comparisons, and range checking to make sure those casts are
3169 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3170 signed/unsigned comparisons.
3172 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3173 avoid signed/unsigned comparisons.
3174 * smob.h (scm_numsmob): Change extern declaration to match.
3176 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3177 avoid signed/unsigned comparisons.
3178 * ports.h (scm_numptob): Change extern declaration to match.
3179 (scm_current_load_port, scm_set_port_line_x,
3180 scm_set_port_column_x): New prototypes.
3182 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3183 test code, and it causes warnings.
3185 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3186 gh_uniform_vector_ref): Added prototypes.
3188 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3189 debugging support unconditionally. That's backtrace.c, stack.c,
3190 debug.c, and srcprop.c.
3191 (EXTRA_libguile_la_SOURCES): Omit those from here.
3192 * Makefile.in: Regenerated.
3194 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3196 * options.c (scm_options): Bugfix: Allow empty list of options!
3198 * debug.c, debug.h (scm_single_step): Removed.
3199 (scm_with_traps): New procedure. This procedure could easily be
3200 written in Scheme but needs to be highly optimized.
3202 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3204 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3205 Check SCM_TRAPS_P before trapping.
3207 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3209 Changes to avoid signed/unsigned comparison warnings.
3210 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3211 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3212 so they can have appropriate types for each application. Make i
3213 signed. Use initializers in some spots. I'll probably pay for
3215 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3216 (scm_must_realloc): Make nm unsigned.
3217 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3218 (scm_init_storage): Use prototype-style definition, and make the
3220 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3221 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3223 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3224 avoid signed/unsigned comparison warnings, and because the return
3225 value of readlink may be -1. Don't bother casting the third
3226 argument to readlink.
3228 * filesys.c (scm_dirname, scm_basename): Move these to their own
3229 page, at the end of the file.
3230 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3232 * eval.h (scm_eval_options_interface): Add external prototype for this.
3233 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3235 * eval.c (scm_lookupcar1): Make this static.
3237 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3238 Make these prototype declarations, not K&R-style.
3240 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3241 unsigned comparison warning.
3243 * appinit.c: File removed. It had a single function in it, empty,
3244 whose reason for existence is explained in no documentation or
3245 comment. I think it's there as a default for some Tcl-style
3246 initialization, but Tcl abandoned that approach a while ago.
3247 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3248 (BUILT_SOURCES): Remove appinit.x.
3249 * Makefile.in: Regenerated.
3251 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3253 * Makefile.in: Regenerated using the last public version of
3254 automake, not the hacked Cygnus version.
3256 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3258 Remove Totoro kludge.
3259 * Makefile.in, scmconfig.h.in: Regenerated.
3260 * init.c, readline.c: Don't check if TOTORO is #defined.
3262 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3264 * Makefile.am: Adjust for new thread configuration system.
3265 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3266 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3268 (THREAD_LIBS): Definition deleted; automake will generate such
3269 things automatically.
3270 * Makefile.in: Regenerated.
3272 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3274 Simplify smob and port marking; set the mark bit in the generic
3275 marking code, and make marker routines only responsible for
3276 turning up outgoing pointers.
3277 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3278 before calling the marking function. Don't call the marking
3279 function if it's zero.
3280 * markers.c (scm_mark0): Just return #f. This function isn't
3281 necessary at all now, but it's harmless to call it. We'll leave
3282 it in so other folks' code doesn't croak at link time.
3283 (scm_markcdr): Don't call SCM_SETGC8MARK.
3284 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3285 * dynl.c (mark_dynl_obj): Same.
3286 * root.c (mark_root): Same.
3287 * srcprop.c (marksrcprops): Same.
3288 * unif.c (markra): Same.
3289 * variable.c (scm_markvar): Same.
3290 * ports.c (scm_markstream): Same.
3291 (void_port_ptob): Specify zero for our marking function.
3292 * debug.c (debugobjsmob): Same.
3293 * dynwind.c (guardsmob): Same.
3294 * filesys.c (dir_smob): Same.
3295 * fluids.c (fluid_smob): Same.
3296 * fports.c (scm_fptob, scm_pipob): Same.
3297 * mallocs.c (mallocsmob): Same.
3298 * regex-posix.c (regex_t_smob): Same.
3299 * smob.c (freecell, flob, bigob): Same.
3300 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3301 * throw.c (jbsmob, lazy_catch_funs): Same.
3303 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3305 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3306 scm_copy_tree on code in order not to let memoized code to leak
3307 out. Thus, scm_copy_tree needs to copy vectors as well since
3308 quasiquote can introduce evaluated code also inside vector
3311 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3313 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3315 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3316 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3319 * unif.c: Say that ivect and uvect are of type signed and unsigned
3320 long instead of int in commentary so that it correctly describes
3323 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3325 * stime.c: Removed declaration of strptime. (It should be
3326 declared by the system headers. If it turns out that some systems
3327 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3329 * stime.h: Renamed TIMEH --> STIMEH
3331 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3332 to increase portability, don't use structure assignment.
3333 (Thanks to Nicolas Neuss.)
3335 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3337 (finalize_fd_sets): Added empty statement after last case label.
3338 (Thanks to Nicolas Neuss.)
3340 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3343 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3345 * init.c, readline.c: OK, I won't have these readline.x bug
3346 reports anymore. We've had them since April. The current reason
3347 is a completely unintelligible failure of totoro.red-bean.com to
3348 do the test for rl_getc_function in libreadline correctly. This
3349 kludge overrides the test if we're on totoro so that the snapshot
3350 generation process can work.
3352 * readline.c: Define a strdup replacement if not existent on system.
3354 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3356 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3357 This change makes scm_make_vector R5RS compatible. We cannot keep
3358 the third argument since people want to be able to deduce the form
3359 of the C function call only by looking at R5RS. (At the same time
3360 we have removed some unnecessary complexity!)
3362 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3363 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3364 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3365 argument in call to scm_make_vector.
3367 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3369 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3370 This macro is useful in applications.
3372 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3374 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3375 (scm_parse_path, scm_search_path): New Scheme level procedures.
3377 * load.h (scm_internal_parse_path, scm_parse_path,
3378 scm_search_path): Declared.
3380 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3382 * filesys.c (dirname, basename): New procedures.
3384 * init.c (scm_boot_guile_1): Removed condition around
3387 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3388 new data type (guards) for representation of C level guards and
3389 data on the wind chain.
3390 (scm_internal_dynamic_wind): New function.
3392 * dynwind.h: Declare scm_internal_dynamic_wind.
3394 * root.h (scm_root_state): Added scm_cur_loadp.
3396 * root.c (mark_root): Added comment about cur_loadp.
3398 * load.c: #include "dynwind.h";
3399 (scm_primitive_load): Use scm_inner_dynamic_wind to update
3402 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3404 * ports.c (current-load-port): New procedure.
3406 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3408 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3409 not a tty, return #f.
3411 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3412 to Julian Satchell and Roland Kaufmann.)
3414 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3415 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3417 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3419 * debug.h, debug.c (scm_start_stack): New function. Implements
3420 the guts of old scm_m_start_stack.
3422 * debug.c (scm_m_start_stack): Use scm_start_stack.
3424 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3425 start_stack and restart_stack. (These have static scope.)
3427 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3429 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3430 readline functions to come in release 2.3. (Thanks to Chet
3432 (handle_errors): Use the above functions.
3434 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3436 * readline.c: Improvements for readline support: Handle errors
3437 better; Implement before-read-hook.
3439 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3441 * init.c (scm_boot_guile_1), readline.c: Test for
3442 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3443 assure that we have version >= 2.1.)
3445 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3447 * readline.c (scm_readline): Defer interrupts while we're calling
3450 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3451 away the string to add_history.
3452 (completion_function): Do completion for readline. (Thanks to
3454 (scm_filename_completion_function): New procedure: Filename
3456 (current_input_getc): New function. Use this one instead of
3457 standard getc from readline.
3459 * throw.c, throw.h (scm_handle_by_throw): New function: This
3460 handler throws errors to next handler on the dynwind chain.
3462 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3464 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3467 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3469 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3471 (scm_procedure_properties): Modified to return arity together with
3473 (scm_procedure_property): Added the read-only property `arity'.
3474 (scm_set_procedure_property_x): It is an error to set the `arity'
3477 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3478 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3480 * procprop.h (scm_sym_arity): New symbol.
3482 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3483 to set the dispatch procedure of an operator or entity object.
3485 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3486 Made procedure slots read-only.
3488 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3489 scm_tcs_cons_gloc case in zero args switch; Fixed args
3490 construction for operators in scm_tcs_cons_gloc case in two args
3493 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3495 * fluids.c: Removed use of assert.h (in order to avoid
3498 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3500 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3502 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3503 change makes the evaluator safer at the cost of evaluation speed.
3504 It handles the case when the user has added a non-immediate
3505 improper end of the application form, e.g., `(+ 0 . x)'.
3506 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3507 minimize the extra cost as much as possible. The new code is
3508 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3509 problem with structs planted directly in the code (e.g. by a
3510 macro). This no longer causes segmentation fault. (Thanks to
3513 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3514 arg `proc' in order to be able to throw errors; New argument
3517 * Removed extra #include "debug.h"
3519 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3521 * scmsigs.c: Declare usleep as returning void on some systems.
3522 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3525 * coop.c (usleep): Return void on some systems.
3527 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3529 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3531 * coop.c: Changed return type of usleep to int.
3533 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3534 isn't found in the OS.
3536 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3537 isn't enabled. (Thought that I had made this change ages ago...)
3539 * iselect.c: Declare bzero if not defined by OS.
3541 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3543 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3544 condition. (Thanks to John Tobey.)
3546 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3547 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3550 * __scm.h: Start the long-term project of moving to POSIX threads.
3551 Phase 1: Classification of all critical sections.
3552 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3553 for A sections. (See comments in __scm.h for details.)
3555 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3556 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3558 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3560 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3561 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3562 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3563 dependencies on $(srcdir)/Makefile.in
3564 $(top_builddir)/config.status in order to avoid circularity.
3566 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3567 from argc if argc was 0 initially.
3569 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3570 in generation of libpath.h.
3572 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3574 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3575 libguile from 2 to 3.
3577 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3579 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3581 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3583 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3584 scm_set_port_column_x, scm_port_filename,
3585 scm_set_port_filename_x): Removed optional arguments. Added
3586 proper argument checking.
3588 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3589 stack size in machine words.
3591 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3592 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3593 to Ole Myren Röhne.)
3595 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3597 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3598 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3600 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3603 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3604 procedure apply: Copy argument lists before pushing them unto the
3605 environment so that the environment won't get mutated due to
3606 manipulation of procedure arguments. This should perhaps be
3607 regarded as a temporary solution until someone finds a more
3608 efficient one. (Thanks to Maciej Stachowiak.)
3610 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3612 * script.c (scm_compile_shell_switches): Use "guile" as default
3613 zero arg if argc is NULL.
3615 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3617 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3618 is zero. (Thanks to Dirk Herrmann.)
3620 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3622 * ports.c (scm_add_to_port_table): First line is now line 0
3623 (was 1). (Interface changed according to suggestion by Per
3626 * backtrace.c (display_header): Add 1 to line and column numbers
3627 when presenting them to the user.
3629 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3630 from debug.c --> eval.c
3632 * eval.h, eval.c (scm_eval_options_interface): New options
3634 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3635 i.e. stacks for new threads.
3637 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3639 * eval.c (unsafe_setjmp): Removed with #if 0.
3641 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3644 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3645 to avoid compiler warnings.
3647 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3649 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3651 * throw.c (handler_message): Print message on current error port
3652 instead of default error port. (Thanks to Maciej Stachowiak.)
3654 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3656 * ports.c (scm_add_to_port_table): allocate in units of
3657 struct scm_port_table *, not struct scm_port_table.
3658 * posix.c (scm_close_pipe): remove the port from the port table
3660 Thanks to Rob Engle for both fixes.
3662 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3664 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3665 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3667 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3669 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3671 * backtrace.c (display_error_body, display_backtrace_body),
3672 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3673 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3674 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3675 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3678 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3679 don't receive the jmpbuf arg anylonger.
3680 (scm_catch): Don't accept a #f tag.
3681 (scm_throw): Check that key is a symbol.
3682 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3684 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3686 * async.c (async_pending): Removed declaration.
3688 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3690 * dynwind.c (scm_wind_chain): New debug function.
3692 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3693 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3694 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3695 extra layer of functions around the body and handler of a thread.
3696 This extra layer makes sure that the handler is called in the
3697 dynamic context of the surround (= empty dynwind list), but under
3698 the *dynamic root* of the body. We can not use the dynamic root
3699 of the surround since that root belongs to another thread => stack
3700 is not handled correctly. It may seem ugly to use this extra
3701 layer, but the extra cost in terms of execution time is really
3702 negligible compared to the total amount of time required to create
3703 a thread, and it would reduce maintainability to duplicate the
3704 crucial and complicated steps performed by cwdr.
3706 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3707 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3708 get re-enabled. The important effect of this is that interrupts
3709 are blocked during thread switching so that thread data structures
3710 don't risk getting messed up by an unfortunate signal.
3711 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3712 seems to do more aggressive optimization which actually move
3713 instructions around in these macros in a fatal way. Therefore:
3714 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3715 just superstitious...)
3716 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3717 This macro should be used instead of SCM_ASYNC_TICK since the
3718 latter doesn't do context switches any more.
3720 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3721 instead of SCM_ASYNC_TICK.
3723 * coop.c, iselect.c: Since thread switches are now performed with
3724 interrupts masked, we can't use the old mechanism of delivering
3725 signals immediately when they arrive. Signals must instead be
3726 delivered when the asyncs run *after* the end of the critical
3727 section in scm_internal_select. But this also means after context
3728 switch so that the signal will be delivered to a different thread.
3729 To avoid this, I have changed the protocol of
3730 coop_wait_for_runnable_thread and friends so that they are allowed
3731 to return the original thread. So, if a signal arrives during
3732 scm_internal_select, we won't any longer be forced do a context
3733 switch, but can remain in the same thread and deliver the signal
3736 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3737 scm_asyncs_pending and made it global.
3739 * iselect.c: Small fixes.
3741 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3742 coop_condition_variable_init, coop_condition_variable_wait,
3743 coop_condition_variable_signal): Changed return type from `void'
3744 to `int'. This is to adhere closer to the pthreads interface.
3745 This, in turn, is part of an attempt to provide C versions of the
3746 mutex and condition variable primitives which can be part of a
3747 frontend to COOP or pthreads.
3749 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3750 coop_condition_variable_destroy): New functions.
3752 * coop-threads.c (scm_wait_condition_variable): Use
3753 coop_condition_variable_wait_mutex.
3755 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3756 Definitions moved to coop-defs.h.
3758 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3759 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3760 scm_cond_destroy): New C interface to mutecis and cond vars.
3762 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3764 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3766 * iselect.c: Now several threads can wait on the same file
3767 descriptor. The behaviour is compatible with OS select: All
3768 threads waiting for the fd return with the same status.
3770 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3772 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3773 Can spawn a thread from application C code.
3775 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3777 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3778 gh_doubles2scm): New functions.
3780 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3782 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3783 commented-out version of gh_eval_str()
3785 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3787 * socket.c (scm_bind): free soka after use.
3789 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3791 * stime.c (tzvar): new variable.
3792 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3793 avoid memory leaks when allocating.
3795 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3797 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3800 * gc.c, tags.h: Doc fixes.
3802 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3804 * eval.c (macro-eval!): Removed. This function was a design bug.
3805 It allowed memoized code to leak out to the scheme level. Most
3806 things that you could do with `macro-eval!' can be done with
3809 1997-12-20 Tim Pierce <twp@skepsis.com>
3811 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3812 scm_fgets now depends on ftell(3) to know how many bytes were
3815 1997-12-15 Tim Pierce <twp@skepsis.com>
3817 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3818 dealing with strings.
3820 1997-12-13 Tim Pierce <twp@skepsis.com>
3822 Make %read-line more suitable for implementing read-line efficiently.
3823 * ioext.c (scm_read_line): Strip the terminating newline from a
3824 string, and return a cons of the string and its terminator.
3826 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3827 of the string that is read is stored in this memory location.
3828 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3829 * genio.c, genio.h (scm_do_read_line): Update caller.
3830 * ports.h (scm_ptobfuns): Update typedef.
3831 * fports.c (scm_fptob, scm_pipob): Update struct.
3833 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3835 * filesys.c (set_element): Return file descriptor.
3836 (fill_select_type): Return the highest file descriptor.
3837 (scm_select): Tell select about the highest file descriptor. On
3838 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3839 Therefore the extra overhead for calculating the maximum fd seems
3840 to be more than compensated. Is this correct? In any case,
3841 scm_internal_select will be much faster with this info.
3842 (scm_select, fill_select_type, set_element): Don't accept any kind
3843 of object in the file descriptor list or vector.
3845 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3847 * iselect.c (finalize_fd_sets): Bugfix.
3849 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3851 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3852 when using scm_internal_select (since we might switch to another
3855 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3857 * simpos.c (scm_system): always define: use sysmissing if not
3858 available. Check for HAVE_SYSTEM instead of _Windows (does
3859 Windows lack system or does it have an unusable one?).
3860 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3861 Let the argument be optional: if not supplied, call system(NULL).
3863 * ports.c (scm_close_port): relax the type check from OPPORTP to
3864 PORTP; closing a closed port is allowed.
3866 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3868 * fports.c (scm_fgets): Return if the last char in a chunk is
3869 newline. When fgets returns a string whose length is `size-1', it
3870 is ambiguous whether a whole line was retrieved, so we must check
3871 explicitly whether a line terminator is present.
3873 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3875 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3876 before taking the CDR. (Thanks to Harald Meland.)
3878 * filesys.c (scm_stat): Slightly optimized.
3880 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3882 * ports.c (scm_close_port): Make sure the port is open before
3885 * guile-snarf.in: Pass args through to gcc in a way that preserves
3886 whitespace boundaries. (Thanks to Greg Badros.)
3888 1997-12-02 Tim Pierce <twp@skepsis.com>
3890 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3891 statement. (Thanks to Doug Evans for pointing this out.)
3893 1997-12-01 Tim Pierce <twp@skepsis.com>
3895 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3897 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3899 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3900 errno macro expansion of this field name. (errno is a C
3901 preprocessor macro on some systems.)
3903 1997-11-29 Tim Pierce <twp@skepsis.com>
3905 * iselect.c: Doc fix.
3907 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3909 * init.c (scm_start_stack): Removed initialization of
3910 scm_the_last_stack_var.
3912 * backtrace.h: Declare scm_the_last_stack_var.
3914 * backtrace.c: Define scm_the_last_stack_var.
3916 * root.c (mark_root): Don't mark the_last_stack_var.
3918 * root.h (scm_root_state): Removed the_last_stack_var.
3920 * throw.c: Added #include "fluids.h"
3921 (ss_handler): `the-last-stack' is now a fluid.
3923 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3924 --> the_last_stack_fluid.
3926 * backtrace.c: Added #include "fluids.h"
3927 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3928 (scm_backtrace): `the-last-stack' is now a fluid.
3930 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3931 after scm_init_fluids.
3933 1997-11-28 Tim Pierce <twp@skepsis.com>
3935 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3937 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3938 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3940 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3942 * iselect.c (coop_next_runnable_thread,
3943 coop_wait_for_runnable_thread): Disable interrupts so that no
3944 async is executed before a potential error_revive.
3945 (scm_internal_select): Disable interrupts during the parts of the
3946 code which manipulate the sleep queue and the file descriptors.
3948 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3950 * Makefile.am: Added iselect.c and iselect.h.
3952 * coop.c (coop_qinit): Initialize fields used by
3953 scm_internal_select.
3954 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3955 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3956 replacement in iselect.c.
3957 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3958 coop_join): If GUILE_ISELECT enabled, use
3959 coop_wait_for_runnable_thread instead of
3960 coop_next_runnable_thread.
3961 (usleep, sleep): New replacements for system functions if
3962 GUILE_ISELECT is enabled.
3964 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3966 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3968 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3969 iselect.h. Implement Scheme level `select' using
3970 scm_internal_select. (See NEWS.)
3972 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3974 * init.c: Call scm_init_iselect.
3976 * iselect.h, iselect.c: New files. Implements
3977 scm_internal_select. (See NEWS.)
3979 1997-11-27 Tim Pierce <twp@skepsis.com>
3981 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3982 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3983 and scm_must_free, since ultimately the string returned will be copied
3984 by scm_makfrom0str anyway. Also, read any characters that may have
3985 been pushed onto the port with scm_ungetc.
3986 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3987 * ioext.c (scm_read_line): Free string after Guilifying it.
3988 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
3990 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3992 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3994 * gh.h: Safely wrap prototypes for c++ usage.
3996 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3998 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3999 gh_repl (argc, argv).
4001 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
4003 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
4004 and to invoke scm_shell().
4005 (gh_launch_pad): took out the loading of boot-9.scm from here,
4006 since it is probably best to let the user control that. In fact,
4007 gh_repl() now invokes scm_shell() which does that.
4009 1997-11-23 Mark Galassi <rosalia@cygnus.com>
4011 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
4014 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
4016 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
4017 yesterday's underscore patch. (Thanks to Marius Vollmer for
4020 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
4022 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
4023 DLSYM_ADDS_USCORE is not defined.
4025 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
4027 * gh_data.c (gh_uniform_vector_length):
4028 (gh_uniform_vector_ref): started implementing the uniform types in
4031 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
4033 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
4034 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
4036 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
4038 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
4039 configure.in was changed).
4041 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
4043 * Makefile.am (modinclude_HEADERS): Include readline.h here.
4044 * Makefile.in: Regenerated.
4046 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
4048 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
4049 OPORT is an `open' port, not an output port.
4051 * filesys.c (scm_close, set_element, get_element, scm_chown,
4052 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
4053 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
4054 * ports.c (scm_port_revealed, scm_set_port_revealed_x,

4073 Minor problems with substring-related tag changes.
4074 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
4075 exactly what we want to leave in to detect substrings.
4076 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
4077 * tags.h: Fix diagrams and comments describing the S tag bit;
4078 remove vestigial remarks about the D tag bit.

4080 * strings.c: Formatting tweaks.
4082 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
4083 variable first; then SCHEME_LOAD_PATH, with a warning message.

4092 (scm_boot_guile_1): Call scm_init_readline, if we have it.
4093 * Makefile.am (libguile_la_SOURCES): Include readline.c.
4094 * Makefile.in: Regenerated.
4095 * scmconfig.h.in: Regenerated, after change to ../configure.
4097 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>

4101 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4103 * gh_data.c (gh_vector_set_x): changed name to make it consistent
4104 with the ! -> _x mapping when going from Scheme to C.
4106 1997-10-19 Mark Galassi <rosalia@cygnus.com>
4108 * gh.h (gh_reverse):
4116 (gh_assoc): added these gh_ functions implemented as macros.
4118 * gh_predicates.c (gh_null_p):
4119 (gh_string_equal_p): added these two missing predicates.
4121 * gh_list.c (gh_append):
4126 (gh_set_cdr_x): added these routines as I go through and try to
4127 complete the picture R4RS functions that should be mirrored in the
4130 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4132 * tags.h (scm_tc7_substring): Changed the comment and code to
4133 conform with the changes below. Folks! We have suddenly two new
4134 free tc7 codes!!! Jummy, jummy!

4167 Don't include "mbstrings.h".
4168 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
4169 (SCM_SYMBOL_SLOTS): Define as 4.
4170 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
4171 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
4172 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,

4191 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
4192 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
4194 1997-10-12 Mark Galassi <rosalia@cygnus.com>
4196 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
4198 * gh_test_c.c (c_vector_test): some improvements on the vector
4201 * gh.h (gh_vector): this used to exist but do the wrong thing.
4202 Now it (almost) does the right thing, though it takes a list
4203 instead of the individual arguments. I need to see how it could
4205 (gh_list_to_vector): added this function as a macro. Corresponds
4206 to Scheme's (list->vector ...).
4207 (gh_vector_to_list): added this function as a macro. Corresponds
4208 to Scheme's (vector->list ...).
4210 * gh_data.c (gh_vector_ref): renamed from gh_vref to
4211 gh_vector_ref, so that it resembles the Scheme routines more.
4212 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
4213 resembles the Scheme routines more.
4214 (gh_make_vector): this used to be (stupidly) called gh_vector().
4215 This is the right name, since it does the same thing as the Scheme
4216 (make-vector ...) procedure.
4218 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4220 * ports.h: #include "libguile/print.h"
4222 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
4223 Some indentation fixes.
4225 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
4226 longer a user field; New field: class_flags.
4228 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
4230 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
4232 * gh_data.c (gh_bool2scm): new function which replaces
4233 gh_int2scmb(), which is now tagged as obsolete.
4235 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4237 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4238 macros should by convention not test for NIMPness.)
4239 (SCM_COERCE_OPORT): Adjust indentation.
4241 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4242 SCM_NIMP test before SCM_PRINT_STATE_P.
4244 * struct.c, struct.h, gc.c: Renamed:
4245 scm_struct_i_layout --> scm_vtable_index_layout
4246 scm_struct_i_vcell --> scm_vtable_index_vcell
4247 scm_struct_i_vtable --> scm_vtable_index_vtable
4248 scm_struct_i_printer --> scm_vtable_index_printer
4249 scm_struct_i_vtable_offset --> scm_vtable_offset_user
4251 * struct.c (scm_print_struct): Use new printer slot; Default
4252 printing: Also output hex code of vtable so that type identity
4253 will be indicated as well.
4254 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4255 Removed struct_printer_var; Removed struct-vtable-offset;
4256 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4257 vtable-offset-user): New constants.
4259 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
4260 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
4261 If this slot contains a procedure, use that to print structures of
4262 the type represented by this vtable.
4264 * print.c (scm_iprin1): Don't print arguments of macro
4265 transformers. (They are always: exp env.); Bugfix: Unmemoize
4266 transformer source with correct environment.
4268 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4270 Streamlining of call-with-dynamic-root:
4272 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
4273 there is now only one catch.
4274 (cwdr_outer_body): Removed.
4275 (cwdr_handler): New function.
4276 (scm_internal_cwdr): New function to perform the function of cwdr
4277 but take args that are more useful to C code. Also, the handler
4278 is now invoked *outside* of the new dynamic root, like the docs
4279 say. We no longer have to catch absolutely all errors, the caller
4280 is responsible for using a handler that does not throw, if he
4282 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4283 * root.h (scm_internal_cwdr): New prototype.
4285 Even more but risky streamlining:
4287 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4288 allocation of the jumpbuf of a root continuation. The changes
4289 below are controlled by it. They are now deactivated.
4290 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4291 the JMPBUF of the scm_rootcont to NULL before returning.
4293 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4294 when they are non-NULL.
4295 (scm_gc_mark): Likewise, mark only when non-NULL.
4297 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4298 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4300 * gc.c (scm_done_malloc): New function.
4301 gc.h (scm_done_malloc): New prototype.
4303 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
4304 (struct scm_print_state) [revealed]: New field.

4306 type checking purposes.
4307 (scm_valid_oport_value_p): New prototype.
4309 * print.c (scm_valid_oport_value_p): New function to check whether
4310 a certain value is acceptable as a port argument.
4311 (scm_print_state_vtable): New variable.
4312 (scm_free_print_state): Set `revealed' field to false.
4313 (scm_iprin1): Call user supplied closure printer with
4314 scm_printer_apply. Print in the traditional way when there isn't
4315 one or when it returns #f.
4316 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4317 Accept a port/print-state pair in addition to just a port.
4318 (scm_prin1): Don't return the print_state to the pool when it has
4320 (scm_printer_apply): Set `revealed' field of print_state to true.
4321 (scm_init_print): Set scm_print_state_vtable.
4322 (print_state_fluid, print_state_fluid_num): Removed.
4324 * throw.h (scm_handle_by_proc_catching_all): New prototype
4325 throw.c (scm_handle_by_proc_catching_all): New function
4327 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4329 * Makefile.in: Regenerated with automake 1.2c.
4331 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4333 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4334 was looping endlessly.
4336 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4338 * strports.c (scm_eval_string): Don't close the port.
4340 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4341 former returns a nice normal integer. (Thanks to Daniel
4344 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4346 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4347 makefile variable as a build parameter called LIBS. The
4348 build-guile program will use this, for the time being.
4349 * Makefile.in: Regenerated.
4351 Thanks to Shiro Kawai:
4352 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4353 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4356 * Makefile.in: Regenerated with automake 1.2a.
4358 * script.c (scm_compile_shell_switches): If we hit the -c or --
4359 arguments, don't set the car of (command-line) to scm_usage_name,
4360 the prettified name of the guile executable; give it the full
4361 path, the way shells usually handle $0.
4363 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4365 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4366 Scheme-level name `array-map' and renamed `serial-array-map' to
4367 `serial-array-map!'.
4369 * backtrace.c: Introduced exception handlers which now enclose
4370 `display-error' and `display-backtrace' so that error reporting
4371 won't get into infinite loops if an error occurs during displaying
4372 of the error. This can very easily happen with user supplied
4373 print call-back routines.
4375 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4377 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4378 the names `serial-array-map' and `array-map' should be removed.)
4380 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4382 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4383 Added #include "objects.h"
4385 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4386 Add #include "feature.h".
4388 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4389 (modinclude_HEADERS): Added objects.h.
4391 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4392 This test is needed at many places in the code and should be
4393 abstracted. (Motivated by the need of this test in libguiletk.)
4395 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4396 (scm_eval_string), load.c (scm_primitive_load,
4397 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4398 Use SCM_EOF_OBJECT_P.
4400 * eval.c (scm_init_eval): Add feature `delay'.
4402 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4404 * scmhob.h: Removed.
4406 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4408 * list.h (SCM_LISTn): New macros. Make list creation in C code
4409 prettier. The idea comes from STk.
4411 * sequences.h, sequences.c, append.h, append.c: Removed. These
4412 files implemented non-R4RS operations which would encourage
4413 non-portable programming style and less easy-to-read code.
4415 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4418 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4419 sequences.h, #include append.h.
4421 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4424 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4426 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4428 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4430 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4432 * eval.c: Added #include "objects.h"
4434 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4437 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4438 adjacent smob numbers.
4440 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4442 * procprop.h: Added declaration of scm_i_inner_name.
4444 * gsubr.c: New global symbol scm_i_inner_name.
4446 * debug.c (scm_procedure_name): Try procedure property
4447 `inner-name' if `name' fails.
4449 * print.c (scm_iprin1): Use scm_macro_name.
4451 * eval.c (scm_m_define): Give names to macros as well; Only the
4452 first top-level definition gives a procedure/macro a name.
4453 Otherwise confusing names can turn up in backtraces.
4454 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4455 `name'; Give names to macros as well.
4457 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4458 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4461 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4463 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4465 (prinmacro): Removed. The code has been moved/merged into print.c
4466 in order to decrease code redundancy. We want macros to print in
4467 a way equivalent to procedures, and it would be silly to duplicate
4468 the required code. (We don't want to maintain two places.)
4469 (macrosmob): Print field is now a NULL pointer.
4471 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4472 scm_macro_transformer): New prototypes.
4473 (scm_tc16_macro): Declared.
4475 * print.c (scm_iprin1): Added code for printing of macros. Macros
4476 are now printed in a way equivalent to procedures.
4478 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4480 * procs.h (scm_closure_p): Added declaration.
4482 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4484 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4485 Shouldn't pass "heap" as the subr name.
4487 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4489 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4490 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4491 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4492 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4493 SCM_BOOL_T. Any non-false value is true.
4495 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4497 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4498 scm_gensym): Added prototypes.
4500 * symbols.c (scm_gensym): New function. This will speed up
4501 certain types of applications (such as macro systems) which
4502 generate lots of symbols.
4504 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4506 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4508 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4510 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4511 specifier, since (2) or (2 . 3) would cause SEGV.
4512 (scm_transpose_array): more argument checking fixes.
4514 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4516 * Makefile.in: Regenerated.
4518 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4520 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4522 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4524 * error.c, error.h (scm_error_callback): Removed (see NEWS).

4547 * list.c (scm_list_append_x): Allow non-pair as last argument.
4548 This is consistent with the R4RS append and is probably the
4549 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4551 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4553 * stime.h: prototype for scm_times.

4571 third argument is now optional.
4573 * posix.c (scm_execl, scm_execlp): make the filename argument
4574 compulsory, since omitting it causes SEGV.
4575 (scm_sync): return unspecified instead of #f.
4576 (scm_execle): new procedure.
4577 (environ_list_to_c): new procedure.
4578 (scm_environ): use environ_list_to_c. disable interrupts.
4579 (scm_convert_exec_args): take pos and subr arguments and
4580 improve error checking.
4582 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4584 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4585 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4586 argument to SCM_ASSERT. Furthermore, the name of the function
4587 should be passed as first argument when signalling
4588 SCM_WNA. (Thanks to Thomas Morgan)
4590 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4591 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4592 dispatches on the number of actual args has a default case
4593 reporting an internal error. This is a vestige from a version
4594 that mallocated a SCM vector to hold the arguments. In the
4595 current version this check is too late: if it ever happens we will
4596 have already overstepped the bounds of the array.
4598 Also, the patch [...] adds a check for too many actual arguments."
4600 mdj: Removed check for "internal programming error".
4602 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4604 * gh_io.c (gh_write): New function.
4606 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:

4619 fold in the functionality of scm_primitive_dup.
4620 (scm_primitive_dup): deleted.

4624 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
4625 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4626 ultrix are defined. Use setvbuf instead of setbuf.
4627 (scm_setvbuf): new procedure.
4628 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
4629 (scm_setfileno): moved from ioext.c.

4643 (scm_init_print): Initialize them.
4644 (scm_iprin): If print_state_fluid carries a print_state, use that
4645 instead of creating a new one.

4647 definitions to help with calling printer functions written in
4649 * print.h (scm_printer_apply): New prototype.

4665 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4667 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
4668 to a list of length zero correctly.
4670 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

4692 stream has been set.
4693 (scm_duplicate_port): deleted, there's now an implementation in

4746 data. (dynl_smob): Use it.
4747 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4748 the dynamic object data below the linking of the object to avoid
4749 memory leak when the linking code throws an error. Now the code
4750 leaks a whole dynamically linked library when must_malloc throws,
4751 but that should be much less likely.
4753 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4755 Changes to compile under gnu-win32, from Marcus Daniels:

4793 think this is left over from the (eq? '() #f) days.
4795 * read.c (recsexpr): Give this a dummy definition if
4796 DEBUG_EXTENSIONS isn't #defined.
4798 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

4826 turn off REG_EXTENDED.
4827 (scm_init_regex_posix): New regexp/basic symbol.
4828 (REG_BASIC): #define this if it is not already present.

4875 (cwdr_outer_body): New function, to establish the user's handler,
4876 and pass control to cwdr_inner_body.

4888 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4889 the feeling that real thread systems will not need this...

4893 Try to detect when people are using one version of libguile and a

4905 primitive definitions under their Scheme names.
4907 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4908 1:2. Helps avoid confusion between installed and uninstalled libs.
4910 * scmconfig.h.in: Regenerated. (Needed after June 3 change to

4923 * ports.h: new prototype.

4933 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4935 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA

4939 * tag.c (scm_tag): Remove unreachable statement.
4940 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4941 top of the word, it should be unsigned.
4943 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4944 is defined, to avoid warnings; it's only used in the
4945 conflict-checking code. Which might go away anyway.
4946 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4947 conditionals; put the label definition in an #if too, to stifle
4950 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4951 ChangeLog-threads in the distribution.
4952 * Makefile.in: Regenerated.

4984 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
4986 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
4989 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
4991 * eval.c (scm_lookupcar1): New procedure to cope with a race
4992 condition during lookup (when using threads).
4993 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4994 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4997 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4999 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
5000 supplied. (Change from Tim Pierce.)
5002 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
5004 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
5005 23:47:01 1997" changelog: Slots are now initialized with `#f' by
5006 default and not `()'. `#f' is the canonical non-value in Scheme,
5009 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5011 * struct.c (struct_printer): New variable that holds a handle on
5012 the Scheme variable *struct-printer*. This variable can be set by
5013 Scheme code to override the printing of structures.
5014 (scm_print_struct): If struct_printer is set, call it. If it is
5015 not set, or returns #f, print the structure in the old fashion.
5016 Include "eval.h" for scm_apply.
5018 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
5020 * struct.c (scm_struct_ref, scm_struct_set_x): Use
5021 scm_struct_i_n_words to get the number of fields, not
5022 -scm_struct_n_extra_words.
5024 On the route to fancier struct printing:
5025 * struct.c (scm_print_struct): New function to print a structure.
5026 Include "genio.h" to support it. This function doesn't do
5027 anything interesting right now, but I think it should be here
5029 * struct.h: Include "print.h" and add prototype for
5031 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
5032 print structures ourself.
5034 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5036 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
5037 before applying the handler in case it doesn't return.
5039 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
5041 * scmsigs.h, async.h: updated.
5043 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
5046 * posix.c (scm_uname): interpret only negative values as an error.
5047 Solaris normally returns a positive value.
5049 * script.c (scm_compile_shell_switches): if we are not going into
5050 an interactive repl, set scm_mask_ints to zero so that asyncs can
5053 * simpos.c (scm_system): don't ignore/unignore signals around
5056 * posix.c (scm_open_pipe): don't ignore/unignore signals around
5059 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
5060 done in boot-9.scm instead.
5062 * scmsigs.c, async.c: Major rewriting of signal handling code.
5063 (scm_sigaction): new procedure.
5064 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
5066 (scm_raise): return unspecified, throw error on failure.
5068 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5070 * regex-posix.c (scm_init_regex_posix): Register the "regex"
5071 feature, to help boot-9.scm decide whether to import the regex
5074 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5076 * eval.c: Include scmconfig.h at the beginning of the file so that
5077 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
5080 * regex-posix.c: #include "_scm.h" before conditionally #including
5081 <regex.h>; the former defines HAVE_REGCOMP.
5083 * regex-posix.c: #include <regex.h> conditionally, so the file is
5084 CPP'able (for dependency scanning) even on systems that don't have
5087 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5089 Add new R4RS-compliant syntax for keywords.
5090 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5091 regardless of the setting of the `keywords' read option.
5092 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5093 can be re-read no matter what the setting of the `keywords' read
5096 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5098 Add support for POSIX regular expressions.
5100 * regex-posix.c, regex-posix.h: New files. (Some code
5101 is taken liberally from rx/rgx.c in the old Guile dist.)
5103 * init.c: Include regex-posix.h.
5104 (scm_boot_guile_1): Call scm_init_regex_posix.
5106 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5107 Add regex-posix.[ch] sources.
5108 * Makefile.in: Regenerated.
5110 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5111 to do this automatically? It didn't for me, bleh.)
5113 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5115 * fports.c (print_pipe_port): New function.
5116 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5117 latter doesn't even take the right arguments.
5119 * Makefile.am: Increment shared lib revision number. I think
5120 sometimes the uninstalled Guile finds the installed shared lib;
5121 Gord says doing this might help. As things turned out, I can't
5122 say whether it does.
5123 * Makefile.in: Regenerated.
5125 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5126 passing it as the closure argument to scm_boot_guile. (Bill
5129 * ports.c (print_void_port, putc_void_port, puts_void_port,
5130 write_void_port, flush_void_port, getc_void_port, close_void_port,
5131 noop0): Use ANSI prototypes instead of K&R declarations, so the
5132 initialization of void_port_ptob gets aggressively type-checked.
5133 Fix arguments of print_void_port and write_void_port. (Bill

5167 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5169 * script.c (scm_find_executable): Use prototype-style definition
5170 here; apparently it's not quite right to have const in a prototype
5171 and then use a K&R declaration. I wonder if stuff like this will
5172 go away if we compile with -Wrequire-prototypes, or whatever that
5173 is... (Bernard URBAN)
5175 * scmhob.h: New text from Bernard URBAN.
5177 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5179 * script.c: Don't #define const on hpux. Configure takes care of
5180 this. (Thanks to Larry Schwimmer.)
5182 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5183 decide whether to #include <unistd.h>, instead of listing a bunch
5184 of systems. Don't #include stdio twice. Removed dyked-out
5185 definition of scm_find_impl_file.
5187 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5189 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5190 library version info to 1:0.
5191 * Makefile.in: Regenerated.

5197 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5198 throw.c: Update copyright years; these files have been worked on
5199 significantly in 1997, but only had copyright years for 1996.
5200 Also, change name of copyright holder on some from Mikael
5201 Djurfeldt to Free Software Foundation; he has signed papers
5202 assigning the changes to the FSF.
5204 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5205 reason not to give the user the option.
5207 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5208 Return #f on end-of-file when scanning table (i.e. when called
5209 with no arguments). Try to catch errors, when we can.
5210 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5212 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5213 external declarations. These are useful.
5215 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5217 * posix.c: don't include <sys/select.h> or define macros for
5218 select, since they were not used in this file.
5220 * filesys.c (scm_select): make the fifth parameter microseconds,
5221 not milliseconds. let the fourth parameter be either a real value
5222 or an integer or #f. The first, second and third arguments can
5223 now be vectors: the type of the corresponding return set will be
5225 (set_element, get_element): new static procedures.
5227 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5229 * strports.c (scm_eval_string): New function.
5230 (scm_eval_0str): Trivially re-implemented in terms of
5232 * strports.h (scm_eval_string): New extern decl.
5234 * net_db.c (h_errno): Add extern decl for this.
5236 * fports.c (local_pclose): New function.
5237 (scm_pipob): Use it in the initializer here.
5240 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5241 Use a meaningful error message when signalling an error. For
5242 this, scm_gethost must check h_errno rather than errno.
5244 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5246 * Makefile.in: Regenerated, using automake-1.1p.
5248 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5250 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5251 not SCM_UNSPECIFIED.
5253 * script.c (scm_compile_shell_switches): don't append (quit) if
5255 (scm_shell): call scm_exit_status and exit on the result of the
5258 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5260 Ensure that shared substrings are handled properly when passed to
5261 a system call or other foreign function. Many thanks to Tim
5263 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5264 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5265 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5266 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
5267 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
5268 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5269 (scm_display_error_message): use RO macros when strings may be RO.
5270 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5271 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5272 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

5276 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
5277 scm_strftime), vports.c (scm_make_soft_port): use
5278 SCM_COERCE_SUBSTR to make sure shared substrings are
5281 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5283 * error.c (scm_error): Add newline to error message.
5285 * init.c (scm_init_standard_ports): Doc fix.
5287 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5289 * dynl-shl.c: Completely replaced with new code from Bernard
5292 * script.c (scm_ice_9_already_loaded): New variable.
5293 (scm_compile_shell_switches): Use it.
5295 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5297 * filesys.c (scm_input_waiting_p): add missing third argument to
5300 * stime.c (scm_localtime): copy the result of localtime before
5301 calling gmtime in case they share a buffer.
5302 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5305 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5307 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5309 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5311 * Makefile.am (check-local): New target, which causes 'make check'
5312 to run gh_test_c and gh_test_repl, with some trivial input.
5313 * Makefile.in: Rgnrtd.
5315 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5317 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5320 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5322 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5323 sure how this was supposed to work.
5324 (scm_async_click): don't send SCM_TICK_SIGNAL.
5325 (scm_init_async): don't initialize %tick-thunk.
5327 * the following change doesn't affect the Scheme interface:
5328 gc-thunk is called at the end of garbage collection. however it's
5329 no longer implemented by pretending it's a signal.
5331 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5332 system async corresponding to scm_gc_thunk.
5333 * async.h: declare scm_gc_async.
5334 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5335 gc-thunk directly, instead of going through a signal handler.
5336 (scm_gc_async): new variable, points to the GC system-async.
5337 (scm_init_async): save the GC async as scm_gc_async instead
5338 of using system_signal_asyncs.
5339 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5341 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
5343 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
5344 Don't screw up if we're interrupted.
5345 * Makefile.in: Regeneradet.
5347 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5349 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5351 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5352 we're not using AM_INIT_GUILE_MODULE any more.
5353 * Makefile.in: Reneregated.
5355 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5357 Functions for finding variable bindings, grace à Tim Pierce.
5358 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5359 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5361 Get 'make dist' to work again.
5362 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5363 * Makefile.in: Regenerated, like a surry without a fringe on top.
5365 Changes for reduced Guile distribution: one configure script,
5367 * configure.in, configure: Removed.
5368 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5369 real configure script lives.
5370 * Makefile.in, scmconfig.h.in: Regenerated.
5372 * init.c: #include "script.h", to get prototype for script.c's
5375 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5377 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5378 scm_must_malloc, not raw malloc.
5380 * script.c (scm_compile_shell_switches): Dyke out debugging output
5383 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5385 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5387 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5388 system has them. Hope this is safe. Previously
5389 sys/timeb.h was included if HAVE_FTIME was defined or if
5390 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5391 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5393 * ioext.c (scm_setfileno): add missing third argument to
5394 scm_misc_error call.
5396 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5398 * eq.c (scm_equal_p): Correctly compare strings of different
5399 varieties. (Thanks to Tim Pierce.)
5401 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5403 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5404 #! block comment must occur on a line all by itself.
5406 Move most of the guts of shell command processing into libguile,
5407 so guile.c can be very small (and eventuallly auto-generated. (I
5408 mean, generated mechanically, not self-generated. Hmm.))
5409 * guile.c, script.c, script.h: New source files.
5410 * init.c (scm_boot_guile_1): Call scm_init_script.
5411 * libguile.h: #include "script.h".
5412 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5413 targets, for new executable.
5414 (libguile_la_SOURCES): Mention script.c.
5415 (modinclude_HEADERS): Add script.h.
5416 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5417 not dynamic linking is enabled. This is because we're generating
5418 executables now. Move CY_AC_WITH_THREADS call after those, so the
5419 values of cy_cv_threads_libs captures the libs chosen above.
5420 * Makefile.in, configure, aclocal.m4: Regenerated.
5422 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5423 We don't maintain this interface any more, and it just confuses
5426 * alloca.c: #include <scmconfig.h>, not <config.h>.
5427 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5428 it'll get included in disties.
5430 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5432 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5433 be distributed, because they confuse people.

5441 * configure, scmconfig.h.in: Regenerated.
5443 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5445 * backtrace.c (scm_backtrace): Split message string across
5446 newlines properly. GCC is more tolerant of this than other

5451 Merge threads directory into libguile.
5452 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5453 threads.h: New source files.

5459 coop-threads.c.cygnus, coop-threads.h.cygnus.
5460 * configure.in: If we're using threads, include threads.o in
5462 * _scm.h, libguile.h: threads.h lives in this directory now.
5463 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5464 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5465 currently used, but brought along for information's sake.
5466 * ChangeLog-threads: log from old 'threads' directory.
5467 * Makefile.in, configure: Rebuilt.
5469 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5471 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not

5481 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5482 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5484 (EXTRA_libguile_la_SOURCES): ... here.
5485 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5486 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5487 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5488 New variables, describing how to build the gh test programs.
5489 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5490 build the test programs, and we probably should have been linking
5491 libguile.la against them all along, to support AIX shared libs.
5492 Add cflags for threads to CFLAGS; add libs for threads to new
5493 variable THREAD_LIBS, used in Makefile.am.
5494 * ChangeLog-gh: log from old `gh' subdirectory.
5495 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5497 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5499 * acconfig.h: Undo change of Apr 9; including the definition of
5500 PACKAGE in the guile headers conflicts with applications' own
5502 * scmconfig.h.in: Regenerated.
5504 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

5513 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5515 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5516 have S_IFSOCK. This is the case under Ultrix.
5518 * posix.c (scm_status_exit_val, scm_status_exit_val,
5519 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5520 Ultrix versions of WIFSTOPPED, etc., which assume that their
5521 arguments are lvalues (hmm).
5523 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5525 * eval.c: Doc fixes.
5527 * throw.c: Doc fixes; rearranged.
5529 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5531 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5533 * acconfig.h: Added entry for PACKAGE.
5534 * scmconfig.h.in: Regenerated.
5536 Changes to work with automake-1.1n, which has better libtool support.
5537 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5538 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5540 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5542 * Makefile.in: Rebuild.
5544 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5546 * stime.c (scm_mktime): take an optional zone argument.
5547 (scm_localtime): check putenv return value.
5548 (scm_strftime, scm_strptime): moved from posix.c. move #include
5550 stime.h, posix.h: update prototypes.
5551 (bdtime2c, setzone, restorezone): new static procedures.
5552 (scm_mktime, scm_strftime): use them.
5553 (scm_strftime): don't call mktime before strftime. Use
5554 filltime for return value.
5555 (filltime): convert NULL zname to #f.
5556 (scm_strptime): return a count of characters consumed, not
5557 the remaining string.
5559 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5561 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

5564 Uncomment localtime and mktime.
5566 * configure.in: add AC_STRUCT_TIMEZONE.
5568 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5570 * stime.c (scm_init_stime): don't define ticks/sec.
5571 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5572 return value problem and is still portable.)
5574 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5576 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5577 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5578 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5579 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5580 cpp_err_symbols.c): Corresponding changes.
5581 * Makefile.in: Regenerated.
5583 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5585 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5586 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5587 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5588 * putenv.c: new file, from sh-utils 1.12.
5590 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5591 since allocation isn't for Scheme objects.
5592 (scm_putenv): copy strings before placing in the environment.
5594 * stime.c (scm_current_time): throw an error if time returns -1,
5595 instead of returning #f.
5596 (scm_get_internal_real_time, scm_get_internal_real_time): use
5597 scm_long2num for return value instead of SCM_MAKINUM.
5599 * stime.h: prototypes updated.
5601 * stime.c (scm_time_in_msec): apparently unused, deleted.
5603 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5605 * configure.in: check for gettimeofday.
5607 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5608 which may be more usefully portable than a gettimeofday interface.
5610 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5612 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5614 * Makefile.in: Regenerated.
5616 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5618 * stime.c (filltime): recovered static procedure.
5619 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5622 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5623 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5625 * posix.c (scm_mknod): split the mode argument into type and perms
5626 arguments, like the extra fields returned by stat.
5628 * fports.c (scm_pipob): set the close, free and print procedures.
5629 (scm_close_pipe): new procedure.
5631 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5632 define them in boot-9.scm
5634 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5636 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5637 wan't defined. Don't include fd.h.
5639 * Previously fd.h was regenerated whenever configure was run,
5640 forcing a couple of files to be recompiled.
5642 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5643 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5644 Check for _fileno as well as _file.
5646 * ioext.c: don't fd.h.
5647 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5650 * Change the stratigy for getting information about errno
5651 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5652 generating lists of symbols during the build process, which will
5653 not always work, include comprehensive lists in the distribution.
5654 To help keep the lists up to date, the "check_signals" and
5655 "check_errnos" make targets can be used.
5657 * configure.in: don't check for a command to extract errno codes.
5658 * Makefile.am: update file lists, remove errnos.list and errnos.c
5659 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5660 check_errnos targets.
5661 (CLEANFILES): remove errnos.c and errnos.list, add
5662 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5663 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5664 * errnos.default: deleted.
5665 * cpp_signal.c: new file.
5666 * cpp_errno.c: renamed from errnos_get.c.
5667 * cpp_err_symbols, cpp_sig_symbols: new files.
5668 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5669 * error.c (scm_init_error): #include cpp_err_symbols instead of
5671 * posix.c (scm_init_posix): don't intern signal symbols. #include
5674 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5676 * strop.c (scm_i_index): allow the lower bound to be equal to the
5677 length of the string, so a null string doesn't always give an error.
5679 * posix.h: new prototypes.
5680 * posix.c (scm_status_exit_val, scm_status_term_sig,
5681 scm_status_stop_sig): new functions, as in scsh. They break down
5682 process status values as returned by waitpid.
5684 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5686 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5687 configure doesn't know about it.
5689 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5691 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5693 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5694 which defines C variables with global linkage.
5696 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5698 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5701 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5703 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5704 has time to check why this doesn't work well with continuations.
5706 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5708 * Fix shell syntax error; some shells won't tolerate
5709 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5711 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5713 * posix.c (scm_uname): throw an error if uname fails instead
5716 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5718 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5721 * async.c (scm_ints_disabled): definition moved from error.c.
5723 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5725 * acconfig.h: Removed PACKAGE.
5727 * scmconfig.h.in: Regenerated.
5729 * snarf.h: g++ says it's non-portable not to specify the first
5730 argument in a varargs declaration. I introduced the first
5731 argument by using preprocessor conditionals.
5733 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5735 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5736 (scm_freopen): use RO string macros for filename and modes.
5737 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5739 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5740 (scm_mknod): use RO string macros for path.
5742 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5743 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5745 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5746 use SCM_ROSTRINGP and SCM_ROCHARS.
5748 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5750 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5753 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5754 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5755 support for byte vectors.
5757 * print.c (scm_iprin1): Limit number of vector elements printed
5758 according to pstate->length.
5760 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5762 * backtrace.c (scm_display_error_message): don't segv if message
5765 * error.h: prototype for scm_error_scm.
5767 * error.c (scm_error_scm): new procedure, reimplements scm-error
5768 in C and uses scm_error.
5770 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5772 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5773 pointer to the Scheme variable read-hash-procedures and intern it
5774 in scm_init_read. Modify scm_read_hash_extend and
5775 scm_get_hash_procedure to use the pointer.
5777 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5779 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5780 (SCM_KEYWORD_STYLE): defined.
5782 * read.c (scm_read_opts): add a keywords option. This isn't a
5783 boolean option, in case someone wants to add support for DSSSL
5785 Setup scm_keyword_prefix symbol.
5786 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5788 I've left keyword support disabled by default, since it doesn't
5789 seem to break the module system and it gives R4RS standard behaviour.
5790 It can be reactivated with (read-set! keywords 'prefix).
5792 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5794 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5795 before constructing arbiter.
5797 * eval.c (scm_m_define): Bugfix: Check that the object is a
5798 closure before setting the procedure property!
5800 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5802 * ports.c: Removed `ungetc-char-ready?'.
5804 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5806 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5807 (idea from Mikael: make it a pair so scm_permanent object only
5809 (scm_read_hash_extend): don't call scm_permanent_object.
5810 (ideas from Mikael): if chr is already in the list, replace its
5811 procedure instead of appending it again. If proc is #f, remove
5813 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5815 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5817 * gdbint.c (gdb_read): update scm_lreadr usage.
5819 * load.h: update prototypes.
5821 * load.c (scm_primitive_load, scm_read_and_eval_x,
5822 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5824 * read.h: add prototype for scm_read_hash_extend. Change args for
5827 * read.c (scm_read_hash_procedures): new variable.
5828 (scm_read_hash_extend): new procedure.
5829 (scm_get_hash_procedure): new procedure.
5830 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5831 for extended # processing.
5832 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5833 scm_read_token): remove case_i, sharp arguments. Change callers.
5835 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5837 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5838 (SCM_CASE_INSENSITIVE_P): define.
5840 * read.c: add case-insensitive option to scm_read_opts.
5841 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5842 to determine whether to convert symbol case.
5843 (default_case_i): definition removed.
5844 * read.c (scm_read_token): if case_i, downcase ic before doing
5847 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5849 * configure.in: Added configuration option `guile-debug'.
5850 Configure with --enable-guile-debug if you want a bunch of extra
5851 functions used for debugging when developing Guile.
5853 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5855 * procs.c (make-cclo): New undocumented debugging procedure: Make
5856 compiled closure with internal procedure PROC and length LENGTH.
5857 Only compiled if GUILE_DEBUG is defined.
5859 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5861 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5863 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5865 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5866 with 3 or more args internally to the evaluator.
5868 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5870 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5871 with 3 or more args internally to the evaluator. This is mainly
5872 because we don't want to pass entry and exit points of the
5873 debug support twice, but it also seems to increase the speed of
5874 the evaluator for such calls (e. g. (+ 1 2 3)).
5876 * backtrace.c (scm_display_application): New procedure:
5877 display-application; Set fancy printing parameters individually
5878 for different types of display (backtrace, error, application).
5879 (These should of course be customizable!)
5881 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5882 clear the CHECK-flags.
5884 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5886 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5888 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5890 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5891 from pairs with a GLOC in the car.
5893 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5894 otherwise `symbol-hash' will behave badly.
5895 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5896 we get segmentation fault!
5898 * symbols.c: Added #include "weaks.h". New functions:
5899 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5900 moved to an extraneous library when we split libguile.)
5902 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5904 * filesys.c (scm_stat): stat now takes fport arguments too as
5905 documented in the manual.
5907 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5909 * debug.c (scm_single_step): Bugfix: Call continuation with
5910 scm_call_continuation instead of throwing to it.
5912 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5914 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5915 argument wasn't declared to be optional.
5917 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5919 * stime.c (scm_init_stime): Add feature "current-time".
5921 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5923 * throw.h: prototype for scm_exit_status.
5924 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5925 args to derive an exit status. Allows (quit) to work from a
5927 (scm_exit_status): new function.
5930 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5932 * eval.c (scm_deval): Removed some old code.
5933 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5935 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5938 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5941 * procs.c: Introduce the existent C function scm_thunk_p at the
5942 Scheme level as well.
5944 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5946 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5947 used from C to easily lookup the value of a symbol in the current
5950 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5952 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5953 scm_init_unif in this file. This will also fix a previous problem
5956 * configure.in: Added AM_MAINTAINER_MODE
5958 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5960 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5963 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5965 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5966 source files that are not always included in libguile but should
5967 have their dependencies calculated by automake. This variable is
5968 recognized by automake, no further magic is needed.
5969 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5970 to deal exclusively with *.lo files, as it seems. The *.o files
5971 are built automatically when the corresponding *.lo file gets
5974 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5976 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5979 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5981 * unif.c (scm_array_set_x): minor change to argument error checking.
5983 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5985 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5986 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5987 They should only be included in the library at configure.in's
5989 (libguile_la_LDADD): Include the appropriate .lo files here.
5990 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5991 so we know when to build them (and their .lo bretheren).
5992 * configure.in (LIBLOBJS): New substituted variable. We let
5993 configure decide which .o files to include in LIBOBJS, and then
5994 put the corresponding list of .lo files in LIBLOBJS. The latter
5995 is what we pass to libtool.
5996 * Makefile.in, configure: regenerated.
5998 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
6000 * symbols.c (scm_sysintern0): New function. Contains the core of
6001 old scm_sysintern but doesn't take a second value argument.
6002 (scm_sysintern): Now uses scm_sysintern0.
6003 (scm_sysintern_no_module_lookup): Renamed to
6004 scm_sysintern0_no_module_lookup and doesn't take a second value
6005 argument any longer.
6007 * symbols.h (scm_sysintern0: Added declaration.
6009 * options.c (scm_init_opts): Use scm_sysintern0 instead of
6010 scm_sysintern when interning option keys. Otherwise we risk
6011 destroying the values of already interned variables.
6013 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
6014 scheme-level boolean (use SCM_NFALSEP).
6016 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
6018 (scm_backtrace): New function. (C version of old function from
6019 boot-9.scm) Motivation: Make it possible to display backtraces
6020 without depending on boot-9.scm. (I'm uncertain if this
6021 motivation is good enough...)
6023 * root.h (scm_root_state): Add member the_last_stack_var.
6024 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
6026 * root.c (mark_root): Mark scm_the_last_stack_var.
6028 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
6031 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
6033 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
6034 1. mark_lazy_catch didn't mark the smob.
6035 2. Both functions above have standard variants:
6036 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
6037 free_lazy_catch --> scm_free0.
6039 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
6041 * throw.c (scm_internal_lazy_catch): New function.
6042 (scm_lazy_catch): Rewritten to use it.
6043 (scm_ithrow): Handle the new lazy catch representation.
6044 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
6045 that doesn't have a jmpbuf is a lazy catch clause.
6046 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
6047 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
6048 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
6050 (scm_init_throw): Register the new lazy-catch smob type.
6051 * throw.h (scm_internal_lazy_catch): decl for new function.
6053 * throw.c (scm_internal_catch): Doc fixes.
6055 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
6056 configure.in. Including this might cause problems if applications
6057 that link against libguile include their own copies of alloca, but
6058 if they're using autoconf, they should be adding libguile to LIBS
6059 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
6060 the copy in libguile, and things will be okay. (I think.)
6062 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6064 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
6066 strop.h: move prototypes too.
6068 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6070 * posix.c (scm_init_posix): don't intern EINTR since it's now done
6073 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
6074 etc. I deleted them from filesys.c long ago, but didn't
6075 notice they were here too (although ineffective since
6076 sys/stat.h wasn't included).
6078 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
6080 * eval.c: Don't define alloca in GCC case. gcc will automatically
6081 use __builtin_alloca if appropriate.
6083 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6085 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6086 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6087 that values of automatic variables are preserved. See comments
6088 for safe_setjmp for details.
6090 Change from Thomas Morgan:
6091 * variable.c: Include eq.h.
6092 (var_equal): New function.
6093 (variable_smob): Use var_equal as the discriminator for variables.
6095 * throw.c (s_throw): Remove extraneous declaration.
6097 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6098 * eval.c: Add necessary CPP cruft to support that.
6099 * configure, Makefile.in, scmconfig.h.in: regenerated.
6101 Change from Thomas Morgan:
6102 * procprop.c (scm_procedure_properties): Convert the Scheme
6103 boolean returned by scm_procedure_p into a C boolean before using
6104 it as a condition for SCM_ASSERT.
6105 (scm_procedure_property): Likewise.
6107 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6108 indications of Unixness.
6111 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6113 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6115 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6117 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6118 "unknown # object" error messages.
6120 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6121 (scm_i_index) and declare it static. Add a 'direction' argument
6122 to indicate what way the search should go.
6123 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6125 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6126 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6128 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6130 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6132 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6133 to avoid clash with various scsh forks.
6135 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6137 The following two changes (ramap.c, throw.c) are motivated by the
6138 apparent unportability of forward declarations of static arrays of
6139 the form `static foo bar[];'.
6141 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6142 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6144 * throw.c (scm_throw): Moved above scm_ithrow.
6146 * options.h: Removed the extern declarations of scm_yes_sym and
6147 scm_no_sym since these are static.
6149 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6151 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6153 * Makefile.am: remove AWK=@AWK@.
6154 Add a rule for generating errnos.list.
6155 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6157 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6158 don't extract errnos, just set a variable (avoids the
6159 need to recompile error.c just because configure is run.)
6161 * unif.h: update prototypes.
6162 * unif.c (scm_uniform_array_read,write): change the offset and
6163 length arguments to start and end, for consistency.
6165 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6167 * ioext.h: update prototypes.
6168 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6169 scm_read_line_x, it's a more general procedure using an
6170 interface from scsh. read-line and read-line! are now defined
6172 Note that the new read-line trims the terminator
6173 by default, previously it was appended to the returned string. An
6174 optional argument specifies how to process the terminator (scsh
6175 compatible). For the old behaviour: (read-line port 'concat).
6176 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6177 returns a pair, but is converted to multiple values if the scsh
6180 socket.h: update prototypes.
6181 * socket.c (scm_recvfrom): for consistency with other procedures,
6182 take start and end as separate optional arguments.
6183 (scm_recv, scm_recvfrom): don't allow the second argument
6184 to be a size, only a buffer. Change the scheme names to
6185 recv! and recvfrom!. Don't return the buffer.
6187 * ioext.h, posix.h: move prototypes too.
6188 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6189 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6190 "read.h" and "unif.h".
6191 * ioext.c: include "chars.h"
6193 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6195 * dynl.c: The dynamic linking and module registration functions
6196 are now defined even when dynamic linking is not available for the
6197 host system. Some of their functionality can be done without
6198 dynamic linking; when it's really needed, they throw errors.
6200 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6202 * configure.in: Only define DYNAMIC_LINKING when one of the system
6203 dependent functions is detected.
6204 * dynl.c (scm_dynamic_func): New function to get the address of a
6205 function in a dynamic object.
6206 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6207 produced by scm_dynamic_func as the thing to call.
6209 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6211 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6212 (scm_register_module_xxx, scm_registered_modules,
6213 scm_clear_registered_modules): New functions.
6215 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6217 * symbols.c (scm_sysintern): Renamed to
6218 scm_sysintern_no_module_lookup.
6219 (scm_sysintern): New function to take the place of the old
6220 scm_sysintern. It uses the current toplevel lookup closure to give
6221 the symbol its value. This is a temporary hack to put packages
6222 like gtcltk into their own module.
6223 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6224 us whether `scm_top_level_lookup_closure_var' has been initialized
6226 * eval.c (scm_init_eval): Set it.
6228 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6230 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6231 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6233 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6235 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6236 scm_sys_dup): deleted: FD capability will be added to other
6238 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6239 scm_fd_free, fd_smob, scm_intern_fd.
6240 (scm_open): renamed from scm_sys_open. Return a port instead of
6241 an FD object. Make the mode argument optional.
6242 (scm_sys_create): deleted, it's just a special case of open.
6243 (scm_init_filesys): move interning of constants O_CREAT etc.,
6244 here (were previously using SCM_CONST_LONG macro).
6245 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6247 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6248 include "fports.h" and <stdio.h>
6249 (scm_stat, scm_select): don't support FD objects.
6251 * error.h: adjust scm_syserror_msg prototype.
6252 * error.c (scm_syserror_msg): take an extra argument for errno.
6253 Using the global value didn't always work, since it could be
6254 reset by procedure calls in the message or args arguments.
6256 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6257 I don't understand why the check was there (and what about the
6260 * strop.c (scm_string_copy): allow shared substrings to be copied.
6262 * unif.h: corresponding change to prototypes.
6263 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6264 recognize two new optional arguments: offset and length. Allow
6265 the port argument to be an integer (file descriptor, for scsh).
6266 Include <unistd.h> for "read" prototype.
6268 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6270 * socket.c: don't include filesys.h.
6272 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6274 * Makefile.am: add AWK=@AWK@ (?)
6276 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6278 Add a rule to generate errnos.c from errnos.
6279 * error.c (scm_init_error): include errnos.c.
6280 * errnos_cnvt.awk: new file, converts the list of errno codes to
6282 * errnos_get.c: new file.
6283 * errnos.default: new file, contains errnos to try if they can't
6284 be extracted from errno.h.
6285 * configure.in: if using GCC, try and extract errno codes from
6289 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6291 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6292 * Makefile.am: Made libguile into a libtool library.
6293 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6294 Set libtool_libs to indicate that libguile is a libtool library.
6295 See guile/ChangeLog for details.
6296 * .cvsignore: ignore "*.lo", the libtool library objects.
6298 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6300 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6301 use htons in getservbyport argument.
6303 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6305 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6306 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6309 * objprop.c (scm_object_property): No need to take the CDR of the
6310 value returned by scm_object_properties, since Aug 20 change.
6312 * configure.in: When checking for struct linger, #include
6313 <sys/types.h> as well as <sys/socket.h>. I've never known
6314 <sys/types.h> to cause any portability problems, and Solaris's
6315 <sys/socket.h> needs it.
6316 * configure: Rebuilt.
6318 I think the Sun compiler has chosen a perverse way to interpret
6319 ANSI declarations combined with K&R definitions. We'll
6320 appease it a little bit. But when it invades France, we fight.
6321 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6322 * print.h (scm_iprlist): Here too.
6323 * numbers.c (scm_divbigdig): Change definition to match
6324 declaration in numbers.h.
6325 * unif.c (scm_makflo): Change definition to match declaration in
6328 * init.c (scm_boot_guile): Don't return the value of
6329 scm_boot_guile_1. This function doesn't return a value;
6330 scm_boot_guile_1 doesn't return a value (or return at all).
6332 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6335 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6336 compile. I have a feeling this function is a bad idea anyway ---
6337 one should always test for features, not systems.
6339 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6340 semicolons. Only pure luck kept this from being noticed earlier.
6342 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6344 * socket.c (scm_recvfrom): Added missing semicolon.
6346 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6348 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6349 the buffer and start and end positions for scsh networking
6352 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6354 * configure.in: Revert previous change to this file; the problem
6355 is due to transient automake weirdness.
6356 * configure: Rebuilt.
6358 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6359 PLUGIN/guile.libs. configure generates the latter from the former.
6360 * Makefile.in: Rebuilt.
6362 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6363 need this if we install scripts, like guile-snarf.
6364 * configure: Rebuilt.
6366 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6368 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6370 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6372 * socket.c (scm_addr_vector): fix faulty scm_listify.
6374 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6376 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6377 style block comment is no longer considered an error.
6379 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6381 * PLUGIN/guile.libs.in: New file.
6382 * PLUGIN/guile.libs: Removed from repository.
6383 * configure.in: Create PLUGIN/guile.libs from
6384 PLUGIN/guile.libs.in. This is for including additonal libraries
6385 needed for dynamic linking.
6386 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6387 instead of PLUGIN/guile.libs.
6389 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6391 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6393 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6394 occurrences of the given element from the list, not just the
6395 first. This is how the Emacs Lisp functions behave, how the
6396 analogous Common Lisp functions behave, and (I believe) how the
6397 older Maclisp functions worked. I realize that this change may
6398 break code, but it seemed better to break it before the Guile
6401 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6402 Their prototypes were already present in gc.h, but they weren't
6404 (scm_init_storage): Initialize scm_protects.
6405 * root.c (scm_protects): New element of scm_sys_protects.
6407 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6409 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6411 * libguile.h: Added #include "libguile/net_db.h".
6413 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6414 30 change. That file is only meant for communication between the
6415 configuration process and load.c. If code linked against libguile
6416 wants to get at the paths mentioned in libpath.h, it can call
6417 functions declared in load.h.
6419 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6421 * libguile.h: Removed #include "libguile/fdsocket.h"
6423 * net_db.c: Added #include <sys/socket.h>.
6425 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6427 * filesys.c (scm_input_waiting_p): use select in preference to
6428 FIONREAD, since the latter doesn't detect EOF.
6429 Throw error if neither select nor FIONREAD available.
6431 * socket.c (scm_connect): take a port, not a fd object.
6432 (scm_fill_sockaddr): throw an error if fam is not recognised.
6433 (scm_bind): use scm_fill_sockaddr.
6434 (scm_listen): take a port, not a fd object.
6435 (scm_accept): take and return a port. return #f in the car if
6436 address can't be got
6437 (scm_sock_fd_to_port): new procedure.
6438 (scm_socket): use scm_sock_fd_to_port.
6439 (scm_addr_vector): throw error if unrecognised address type.
6440 take an extra argument with the calling procedure name.
6441 (scm_getsockname): take a port. return #f if address can't be got.
6442 (scm_getpeername): take a port. return #f if address can't be got.
6443 (scm_recvfrom): take a port. return #f for address component if can't
6445 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6446 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6448 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6450 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6451 use separate data pointers, to allow them to be designed
6452 independently and reused.
6453 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6454 Renamed from catch_body, catch_handler, and uncaught_throw; made
6456 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6458 (scm_catch): Use the above.
6459 (scm_throw): Don't bother printing a message for an uncaught
6460 throw; we establish a default handler in init.
6461 * throw.h (scm_internal_catch): Prototype updated.
6462 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6464 (struct scm_body_thunk_data): New structure, used as data
6465 argument to scm_body_thunk.
6466 * init.c (struct main_func_closure): New structure, packaging up
6467 the data to pass to the user's main function.
6468 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6469 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6470 scm_internal_catch to establish a catch-all handler, using
6471 scm_handle_by_message. This replaces the special-case code in
6473 (invoke_main_func): Body function for scm_internal_catch; invoke
6474 the user's main function, using the main_func_closure pointer to
6475 decide what to pass it.
6476 * root.c (struct cwdr_body_data): Remove handler_proc member.
6477 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6478 (cwdr_handler): Removed.
6480 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6482 * socket.h (SCM_P): update bind prototype.
6483 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6484 include "feature.h".
6485 (scm_socket): return a port, not a file descriptor object.
6486 include "fports.h" and <unistd.h>
6487 (scm_bind): take a port, not a file descriptor object.
6488 take an extra argument for address args.
6490 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6491 INADDR_NONE, INADDR_LOOPBACK.
6493 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6495 * init.c: include net_db.h and not fdsocket.h.
6496 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6498 * Makefile.am: corresponding changes.
6499 * socket.h: renamed from fdsocket.h, fix names.
6500 * net_db.h: renamed from socket.h, fix names.
6501 * socket.c: renamed from fdsocket.c.
6502 remove _sys from procedure names.
6503 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6504 add "socket" to features list.
6505 * net_db.c: renamed from socket.c.
6506 remove _sys from procedure names.
6507 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6508 add "net-db" to features list.
6509 include "net_db.h". don't include <sys/socket.h> or
6512 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6514 * tags.h (scm_tags): Removed comma at end of last enumerator.
6516 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6518 Don't use GCC extensions to allocate space for debugging frames.
6519 (Here he goes again! Why do we put up with this?!)
6520 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6521 an scm_debug_info structure, not an in-line array of them. Add
6522 'info' member, to say how many vect elements we've used, for eval
6524 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6525 a new variable debug_info_end to mark the end of vect, instead of
6526 the address of the 'info' pointer itself.
6527 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6528 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6529 (SCM_APPLY): Explicitly allocate space for debug.vect.
6530 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6531 * stacks.c: Adjusted for new debug frame structure.
6532 (RELOC_INFO, RELOC_FRAME): New macros.
6533 (stack_depth, read_frames): Use them, and new scm_debug_frame
6534 element 'info', instead of magically knowing that eval frames have
6535 an info pointer sitting after vect.
6536 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6538 (scm_init_stacks): Formatting tweaks.
6540 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6542 Give GCC more control flow information, so it can be sure that
6543 variables aren't used uninitialized.
6544 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6545 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6546 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6547 scm_misc_error): Tell GCC that these functions never return.
6548 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6549 out the field type, call abort if SCM_ASSERT returns, to placate
6551 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6552 scm_wta ever returns. We can't handle this case anyway, and this
6553 gives the optimizer more information.
6554 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6555 scm_wta ever returns.
6557 In some cases, the code is fine, but GCC isn't smart enough to
6558 figure that out; this usually happens when one variable is only
6559 initialized and used when a particular condition holds true, and
6560 we know that condition will never change within a given invocation
6561 of the function. In this case, we simply initialize the variables
6562 to placate the compiler, hopefully to a value which will cause a
6563 crash if it is ever actually used.
6564 * print.c (scm_iprin1): Initialize mw_pos.
6565 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6566 * throw.c (scm_ithrow): Initialize dynpair.
6567 * unif.c (scm_uniform_vector_ref): Initialize cra.
6568 * struct.c (init_struct): Initialize prot.
6569 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6571 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6572 if EXPR contains no expressions.
6574 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6576 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6577 cause an infinite loop (???). So much for the algebraic
6578 equivalency of variable-sized arrays and alloca...
6580 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6582 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6583 a SCM boolean, not a C boolean.
6585 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6587 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6588 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6589 rules for raising scm_mtrigger. Previously, unfortunate but not
6590 unlikely circumstances could result in almost constant invokation
6591 of the gc. Now, this situations should be less likely, but they
6592 are not prevented completely.
6594 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6596 * numbers.c (scm_fuck): Procedure removed; looks like old test
6598 * numbers.h: Prototype removed.
6600 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6602 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6603 array to a pointer, to match my Nov 21 change in eval.c.
6605 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6607 * libguile.h: Added #include "libguile/backtrace.h", #include
6608 "libguile/stacks.h".
6610 * strings.c (scm_string scm_make_string scm_string_ref
6611 scm_string_set_x scm_string_equal_p scm_string_append):
6612 Bugfix according to scm patch from Aubrey Jaffer:
6613 Corrected long-standing
6614 (not (eqv? (integer->char 128)
6615 (string-ref (make-string 1 (integer->char 128)) 0)))
6616 bug found by John Kozak <jk@noontide.demon.co.uk>.
6618 * strports.c, strports.h: Make scm_eval_0str return the value of
6619 the last expression evaluated (previously, it returned void).
6621 * strports.c, strports.h: New function: scm_read_0str. Does what
6624 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6626 * simpos.c (scm_getenv): return #f if string can't be found in the
6627 environment instead of throwing an exception, for compatibility
6628 with numerous other systems.
6630 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6632 * Makefile.am (.c.x): Use guile-snarf.
6633 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6635 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6637 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6639 * backtrace.c (scm_display_error_message): Made non-static, and
6640 renamed from display_error_message.
6641 * backtrace.h (scm_display_error_message): Added extern decl.
6642 * throw.c (uncaught_throw): Use it to display the error message.
6644 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6646 * inet_aton.c: Use #if 0, not #ifdef 0.
6648 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6650 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6651 to convert the returned value.
6652 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6653 the offset argument.
6655 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6657 Add new interface to catch/throw, usable from C as well as
6659 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6660 (scm_internal_catch): New function, replaces...
6661 (scm_catch_apply): Deleted.
6662 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6663 mechanism which is a bit more code, but can be used nicely from C
6664 and implement the Scheme semantics as well.
6665 (scm_internal_catch): This is the replacement; it's named after
6666 the analogous function in Emacs.
6667 (scm_catch): Reimplemented in terms of the above.
6668 (struct catch_body_data, catch_body, catch_handler): New
6669 functions, used by scm_catch.
6670 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6671 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6672 support for new cwdr.
6674 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6677 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6679 * acconfig.h: Added DYNAMIC_LINKING symbol.
6680 * configure.in: Add option and checks for dynamic linking.
6681 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6682 dynl.h: New files for dynamic linking support.
6683 * Makefile.am (libguile_a_SOURCES):
6685 (modinclude_HEADERS): Added "dynl.h".
6686 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6688 * init.c (scm_boot_guile_1): Call
6689 scm_init_dynamic_linking to initialize dynamic linking support.
6691 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6693 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6694 (as we Schemers say). It needs to be global, so that I can tweak
6695 it for the proper operation of unexec.
6696 (scm_boot_guile_1_live): New variable, see above.
6698 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6700 * guile-snarf.sh: Removed.
6701 * PLUGIN/guile.libs: Added dependency for -lm.
6702 * acinclude.m4: Renamed from aclocal.m4.
6703 * PLUGIN/greet: Removed.
6704 * Makefile.am, aclocal.m4: New files.
6705 * configure.in: Updated for Automake.
6707 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6709 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6710 and not top_level_lookup_thunk_var.
6712 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6714 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6716 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6718 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6719 Scheme function, instead of syntax. Single argument is now a
6722 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6724 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6725 scm_ra_divide): Properly terminate statements passed as arguments
6726 to IVDEP macros. (Thanks to Bernard Urban.)
6728 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6729 with non-constant sizes. (Thanks to Bernard Urban.)
6731 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6733 It's an "eval closure", not an "eval thunk." A thunk is a
6734 function of no arguments.
6735 * root.h (struct scm_root_state): Renamed
6736 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6737 (scm_top_level_lookup_closure_var): Renamed from
6738 scm_top_level_lookup_thunk_var.
6739 * root.c (mark_root): Uses changed.
6740 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6741 * init.c (scm_start_stack): Uses changed.
6742 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6743 Change scheme-visible name to *top-level-lookup-closure* from
6744 *top-level-lookup-thunk*.
6746 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6748 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6749 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6751 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6753 * gc.c (struct scm_heap_seg_data): Doc fixes.
6755 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6756 sweeping. Then, prepend each segment's free cells to its
6757 freelist, rather than wiping out the old value. (Thanks to Marius
6760 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6761 scm_check_freelist, scm_debug_newcell): New functions and
6762 variables, for debugging freelist problems.
6763 * pairs.h (SCM_NEWCELL): New debugging version added.
6764 * gc.h (scm_debug_newcell): Added extern declaration, used by
6765 debugging version of SCM_NEWCELL.
6767 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6769 On some systems <libc.h> conflicts with <unistd.h>, and should not
6770 be #included at all.
6771 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6772 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6773 * configure.in: Call it.
6774 * posix.c, filesys.c: Use its results to decide whether or not to
6776 * configure, scmconfig.h.in: Rebuilt with autoconf and
6779 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6781 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6782 pointer to the stdio stream before calling scm_setbuf0, so the
6783 latter will be able to retrieve it. I'm surprised this didn't
6784 segfault earlier. (Thanks to Christopher Lee.)
6786 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6788 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6791 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6793 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6794 number of stack narrowing specifier pairs. The first specifier in
6795 a pair controls inner border, the second the outer border. A
6796 number means cut that number of frames, a procedure object means
6797 cut until that object is found in operator position in a frame.
6799 * root.c (cwdr): Bugfix.
6801 * read.c: Recording of positions disabled by default.
6803 * procs.c (scm_closure_p): New function.
6805 * posix.c (scm_tmpnam): New function.
6807 * load.c: Added #include "throw.h".
6808 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6811 * load.c, load.h (scm_read_and_eval_x): New function.
6813 * eval.c: Renamed debug option "deval" to "debug".
6815 (scm_eval_x): `eval!' is no longer accessible from the scheme
6816 level. Motivation: We can't allow operations which introduce
6817 glocs into the scheme level. Guile's type system can't handle
6818 these as data. Use `eval' or `read-and-eval!' as replacement.
6820 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6821 SCM_CONSP since this is a macro!; Set vframe.prev to
6822 scm_last_debug_frame instead of 0. In this way we can look
6823 "above" the virtual start stack frame if we wish.
6824 (scm_debug_hang): New function: Useful for debugging Guile in
6825 certain tricky situations. Will probably be removed later...
6827 * debug.h: Changed semantics of debug option "backtrace". This
6828 option now only indicates whether we want automatic backtrace at
6831 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6833 * ports.c: #include "filesys.h"
6834 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6836 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6837 Motivation: This is system specific code which is related to file
6838 I/O. It also may use select. Added code by Gary Houston to
6839 detect presence of character in stdio buffers.
6841 * libguile.h: #include "libguile/libpath.h"
6843 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6844 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6845 SCM_SITE_DIR; Install libpath.h among the other include files.
6847 * load.c, load.h (scm_sys_package_data_dir): New function.
6849 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6851 * stacks.h: Bugfix: Don't use tail-array length field as stack
6852 length field! This screwed GC.
6854 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6856 * _scm.h: Added #ifndef around definition of macros min and max.
6858 * __scm.h: Added hooks for threads to plugin to in ints protection
6859 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6860 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6861 the main code in these macros duplicated and spread over multiple
6862 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6863 SCM_THREAD_SWITCHING_CODE.
6865 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6867 * snarf.h: New file.
6868 * guile-snarf.sh: New file.
6869 * Makefile.in (inner_h_files): Added snarf.h
6870 (ancillary, install, uninstall, distclean): Added actions for
6872 (.c.x): Use guile-snarf.
6873 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6874 (gen_c_files): Note that these depend on guile-snarf.
6875 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6876 now in "snarf.h". Added #include "snarf.h" to get them.
6877 * libguile.h: Added #include "snarf.h".
6878 (Patches applied and tweaked by Jim Blandy.)
6880 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6882 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6883 standards suggest against providing prototypes for system
6884 functions. Thanks to Greg Troxel.
6886 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6888 * strports.c (scm_eval_0str): New function.
6889 #include "read.h", to get prototype for scm_read.
6890 * Makefile.in (strports.o): Update dependencies.
6891 * strports.h: New prototype.
6893 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6894 scheme name from "int?" to "integer?". It seems to do the job.
6895 * numbers.h: Rename prototype too.
6896 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6899 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6900 scm_num_eq_p): Rename these according to R4RS conventions: call
6901 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6902 to making libguile R4RS compliant without ice-9...
6904 * load.c (scm_sys_search_load_path): Search for files under all
6905 extensions listed in the %load-extensions variable. If FILENAME
6906 is absolute, return it unchanged, without searching the load path.
6907 (scm_loc_load_extensions): New variable, pointing to
6908 %load-extensions' value cell.
6909 (scm_init_load): Initialize it, and the value it points to.
6910 (scm_primitive_load_path): Improve error reporting.
6912 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6913 of new Scheme variable %load-hook.
6914 (scm_primitive_load): Apply %load-hook to filename.
6916 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6918 * configure.in: add tests for figuring out whether buffered data
6919 is available in a FILE structure, which is needed by char-ready.
6921 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6924 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6925 exceptions using misc_error instead of syserror. It seems a bit
6926 odd to throw an exception if a string can't be found in the
6927 environment, but it's consistent with open-file, stat etc.
6928 (simpos.h): remove sys_ from getenv.
6930 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6931 occurs, throw an error instead of returning errno. Return value
6933 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6935 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6937 * filesys.c (scm_stat2scm): derive file type and permissions from
6938 the stat mode and append them to the returned vector.
6939 There isn't much overhead in doing this and it avoids the need to
6940 work with S_IRUSR et al. in Scheme.
6941 Define symbols scm_sym_regular etc.
6942 (scm_init_filesys): don't intern S_IRUSR etc.
6944 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6945 and s_primitive_load_path.
6947 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6949 * error.h: don't declare error symbols. prototype for scm_misc_error.
6951 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6954 * error.c: use SCM_SYMBOL to set up error keys.
6955 scm_misc_error: new procedure.
6957 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6959 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6960 between `#!' and `!#' is ignored.
6961 (skip_scsh_block_comment): New function.
6963 * feature.c (scm_set_program_arguments): New argument, FIRST.
6964 * feature.h: Update prototype.
6965 * init.c (scm_boot_guile_1): Pass new argument to
6966 scm_set_program_arguments.
6968 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6970 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6971 (scm_boot_guile): Call scm_set_program_arguments here, later than
6972 the old initialization.
6974 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6975 initialization procedure.
6976 - Delete in, out, err arguments; there are other perfectly good
6977 ways to override these when desired.
6978 - Delete result argument; this function shouldn't ever return.
6979 - Rename init_func argument to main_func, for less confusion.
6980 - Delete boot_cmd argument; main_func is more general.
6981 -Add 'closure' argument, to help people pass data to main_func
6982 without resorting to global variables.
6983 - Abort if reentered; don't bother returning an error code.
6984 - Call scm_init_standard_ports to set up the default/current
6985 standard ports; no need to pass them to scm_start_stack.
6986 - Remove code to evaluate the boot_cmd, and start the repl; let
6987 the user do something like that in main_func if they want.
6988 - Remove code to package up a return value; main_func can do any
6990 - Call exit (0), instead of returning.
6991 (scm_start_stack): Don't initialize the I/O ports here; that's
6992 weird. Delete in, out, err arguments. Move guts to
6993 scm_init_standard_ports, scm_stdio_to_port.
6994 (scm_init_standard_ports): New function, to set up current and
6995 default standard ports.
6996 (scm_start_stack, scm_restart_stack): Make these static.
6997 * init.h (scm_boot_guile): Adjust declaration.
6998 (scm_start_stack, scm_restart_stack): Remove externally
6999 visible declarations for these.
7000 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
7002 * fports.c (scm_stdio_to_port): New function. Its guts used to be
7003 written out several times in scm_start_stack.
7004 * fports.h: New declaration for the above.
7006 * feature.c (scm_set_program_arguments): New function.
7007 * feature.h: New declaration for the above.
7009 * ports.c: Formatting tweak.
7011 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
7013 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
7014 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
7015 for obtaining the address of a car or cdr field. Motivation:
7016 &SCM_CXR make assumptions about the internal structure of the
7019 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
7020 Motivation: see SCM_CXRLOC.
7022 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
7023 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
7024 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
7025 Motivation: Safer use. Some other macros are defined in terms of
7026 these operations. If these are defined using the SCM_SETCXR
7027 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
7028 to inefficiency and an <e1> with side-effects could potentially
7029 break. Also, these particular operations are heavily utilized in
7030 the garbage collector. In unoptimized code there will be a
7033 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
7034 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
7035 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
7036 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
7037 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
7038 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
7039 vports.c: Cleaned up use of pairs: Don't make any special
7040 assumptions about the internal structure of selectors and
7041 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
7042 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
7043 (Among other things, this change makes it easier to build Guile
7044 with certain compilers which have problems with casted lvalues.)
7046 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7048 * stacks.c: Improve selection of relevant stack frames when making
7049 a stack object. Introduce one level of indirection in the stack
7050 object to make it possible to "narrow" to a certain region of the
7051 stack. This facilitates making use of more clever algorithms (not
7052 implemented) for selecting relevant frames and gives a cleaner
7053 design since selection of frames can be done independently of
7054 extraction of frames from the real stack.
7055 (scm_stack_id): Also take #t as argument which means look at
7058 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
7059 Turn n_tail into an integer directly representing current number
7060 of frames in stack. Add field tail.
7062 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
7064 * debug.c (scm_make_memoized): Made it available at scheme level.
7065 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
7066 SCM_NIMP before applying heavier predicates in argument checking.
7067 (scm_local_eval): Also take memoized object as argument.
7069 * backtrace.c (scm_display_error): Just a safety measure: Stacks
7070 aren't created with zero length, but should such a strange
7071 creature suddenly turn up...
7073 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
7075 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
7076 `del', for the sake of C++ compilers. (Patch applied by JimB.)
7078 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
7080 * variable.c (scm_make_variable): Make the name hint optional, as
7082 (anonymous_variable_sym): Renamed from variable_sym. All uses
7085 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7086 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7087 of scm_primitive_load_path was also changed to
7088 "primitive-load-path", from "%try-load-path". Callers changed.
7089 We'd like to respect the convention that a function named
7090 "try-mumble" should behave just like the function called "mumble",
7091 but return #f instead of signalling some error.
7092 * load.h: Rename prototypes.
7094 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7096 * print.c (make_print_state, grow_print_state), print.h: Modified
7097 the print state representation: Don't use a tail array for
7098 recording of circular references. Resizing of the print state
7099 structure invalidates the print state pointer. To avoid passing
7100 around an indirect print state reference to all printing
7101 functions, we instead let the print state reference a resizable
7104 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7106 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7107 Don't crash when passed an improper list terminated by a
7108 non-immediate value.
7110 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7112 Allocate data for structures on an eight-byte boundary, as
7113 required by the tagging system.
7114 * struct.c (alloc_struct): New function.
7115 (scm_make_struct, scm_make_vtable_vtable): Call it.
7116 * struct.h (scm_struct_n_extra_words): Bump to 3.
7117 (scm_struct_i_ptr): New "field".
7118 * gc.c (scm_gc_sweep): When we need to free the data, use the
7119 information stored by alloc_struct to find the beginning of the
7120 block allocated to the structure, so we can free it.
7122 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7124 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7127 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7128 (scm_debug_info): New member: id.
7130 * stacks.c: Stacks are now represented as structs; Stacks have an
7131 id given to them by `start-stack'.
7132 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7134 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7135 Changed stack representation.
7137 * debug.c (scm_procedure_name): Try procedure property `name' for
7138 compiled closures aswell.
7140 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7142 * eval.c: scm_i_name moved to gsubr.c
7143 (scm_m_define): Record names of all kinds of procedure
7144 objects. (Earlier, only closures were recorded.)
7146 * procprop.h: Added declaration of scm_i_name.
7148 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7149 (scm_make_gsubr): Record names of compiled closures.
7151 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7153 * debug.c, debug.h: Removed obsolete code.
7155 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7156 stacks.c: Renamed regs --> scm_contregs.
7158 * print.c (scm_free_print_state): Cleanup print state before
7159 returning it to pool. It is better to do it here than in
7160 scm_prin1 since scm_prin1 is called often.
7162 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7163 s_set_source_property_x): Check that first argument is a pair or a
7166 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7167 scm_i_line, scm_i_column and scm_i_breakpoint global.
7169 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7170 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7173 * debug.h: Added debug object smob declaration and macro
7176 * configure.in: Build with backtrace.o and stacks.o if debug
7179 * Makefile.in: Added entries for new files: backtrace.c,
7180 backtrace.h, stacks.c and stacks.h.
7182 * symbols.c (scm_sym2ovcell): Fixed documentation.
7184 * _scm.h (min, max): Added.
7186 * async.c: Moved `min' macro to _scm.h.
7188 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7189 SCM_BACKTRACE_INDENT.
7191 * eval.c: Added new debug options `maxdepth' and `indent'.
7193 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7195 * print.h: Added selector SCM_PRINT_STATE.
7197 * print.c: New functions: scm_make_print_state,
7198 scm_free_print_state.
7200 * print.h: Added declarations for scm_make_print_state,
7201 scm_free_print_state.
7203 * debug.c (scm_m_start_stack): New acro.
7205 * debug.h: Small cleanup.
7207 * init.c (scm_boot_guile_1): Moved scm_init_debug below
7210 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

7235 More prototype-related changes from Marius Vollmer:
7236 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7237 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7238 * ports.h (ptobfuns): Added prototypes. This means some casting in
7240 * fports.c: Added casts for initializations, since the functions
7241 are defined to take FILE * as their stream argument, not SCM.
7242 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7243 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7244 to `char *str_data' to conform to prototype.
7246 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7248 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7250 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7252 * stime.c, stime.h: use SCM_P method.
7254 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7256 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7257 be given at least two arguments. Insist that lst's last element
7258 be a list, but don't make any requirements of its predecessors.
7260 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7262 * eval.c (scm_nconc2last): Revert last change; there seems to be
7263 other stuff going on here.
7265 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7267 * eval.c (scm_nconc2last): Make sure that each element of lst
7268 (which is a list of argument lists, except for the tail) is a
7269 proper list, i.e., finite and terminated by '().
7271 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7273 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7276 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7277 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7280 * vectors.c (scm_make_vector): Fill vectors with the undefined
7281 value, to help make Guile Scheme code more portable to other
7284 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7285 * symbols.h, tags.h: Doc fixes.
7287 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>

7291 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7293 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7294 want to subtract it from the modulus; we just want to leave it
7297 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7299 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to

7304 * throw.c (scm_catch_apply): Finished implementation of
7307 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7309 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7311 (scm_init_filesys): set "i/o-extensions" feature.
7314 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7316 * Makefile.in (root.o): Correct dependencies.
7318 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7320 * Makefile.in: Added dependency entry for root.o.
7322 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7323 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7325 * init.c (scm_start_stack): Set initial root continuation number
7328 * procs.c: New function: scm_thunk_p.
7330 * procs.h: Added declarations of scm_thunk_p.
7332 * root.c: Renamed `call-with-new-root' -->
7333 `call-with-dynamic-root'.
7334 (cwdr): Removed allocation of new root state. This should be done
7335 separately by use of scm_make_root.
7336 (scm_apply_with_dynamic_root): New function: Does what it
7337 sounds like. Needed when spawning threads.
7339 * root.h: Added member last_debug_frame to root state.
7340 Added #include "libguile/debug.h"
7342 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7343 arguments. The motivation is that code in root.c needs catch
7344 functionality, and we want to avoid code duplication.
7345 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7346 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7347 handlers that run without popping the stack into the dynwind
7350 * throw.h: Added prototypes for scm_catch_apply and
7353 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7355 * root.h (scm_root, scm_set_root): Decouple thread support details
7356 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7357 SCM_SET_THREAD_LOCAL_DATA.
7359 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7360 and tortoise scanning loop.
7362 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7364 * Makefile.in: Rebuild dependencies.
7366 * libguile.h: #include "libguile/print.h" before "smob.h", since
7367 the latter uses the print_state structure.
7369 * throw.c (scm_ithrow): Use the correct variable when checking to
7370 see if a given element of scm_dynwinds is a valid catch.
7372 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7373 structure, abort; don't just silently ignore the garbage.
7375 * _scm.h: #include "print.h" here, since it seems to be used just
7377 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7378 strports.c, unif.h: Don't #include "print.h".
7380 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7382 * feature.h (scm_loc_features): Removed external declaration.
7383 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7385 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7387 * feature.c (scm_init_feature): Added threads feature (needs to be
7388 initialized here, since features doesn't exist when
7389 scm_init_threads is called).
7391 * libguile.h: Added #include "libguile/../threads/threads.h".
7392 (This is a kludge to get thread support working. This should be
7395 * configure.in, acconfig.h: Added flags for thread support.
7397 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7400 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7401 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7404 * _scm.h: Added conditional #include "threads.h"
7406 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7407 SCM_THREADS_SWITCHING_CODE.
7409 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7410 allocate the basic dynamic root object.
7411 (scm_boot_guile): Added call to scm_init_root.
7413 * root.c, root.h: Added root smob.
7414 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7415 functions: Implements dynamic roots mostly according to spec in
7416 SCM manual. Main difference is that the second argument is a
7417 throw handler rather than an error "thunk".
7419 * root.h: Added declaration of scm_init_root.
7421 * root.c: Added #include "genio.h", #include "smob.h", #include
7422 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7424 (scm_init_root): Added #include "root.x".
7426 * throw.c: Added #include "stackchk.h"
7427 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7428 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7429 can be used in scm_call_with_new_root; Added reenabling of stack
7430 checking when catching a throw.
7432 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7434 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7436 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7437 element is not found, as per R4RS.
7439 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7441 * list.c: Doc fixes throughout.
7443 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7445 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7446 declare the char * to be const. Avoids a warning in rgx.c.
7448 * ports.h: spelling fix.
7450 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7453 * load.c (scm_sys_try_load_path): throw an error if file not found
7454 (like it says it in NEWS).
7456 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7458 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7459 PROPS slot to '(), not #f; it's an empty alist.
7461 * throw.h, throw.c: Use SCM_P instead of #if hair.
7463 Remove special support for uncaught throws; see throw.c for
7465 * throw.c (uncaught_throw): New function.
7466 (scm_ithrow): Call uncaught_throw if we don't find a throw
7467 target; don't mess with scm_bad_throw_vcell.
7468 (scm_bad_throw_vcell): Variable deleted.
7469 (scm_init_throw): Don't initialize it.
7471 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7474 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7476 * numbers.c (scm_istr2int): If the number is short (as most
7477 numbers are), just call scm_small_istr2int to deal with it.
7478 (scm_small_istr2int): New function, created by un-#ifdefing the
7479 non-bignum version of scm_istr2int and renaming it.
7481 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7483 * load.c (scm_sys_try_load): don't check whether value returned
7484 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7485 Change the Scheme name from %try-load to primitive-load.
7487 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7488 Can avoid passing a message, allowing it to be derived in the
7489 error handler (e.g., if we want to throw to the key both from
7492 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7494 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7495 references now have a new appearance which is more compact and
7496 also gives a clue about what the target of the reference is.
7497 By setting parameters in the print state, more fancy printing can
7498 be achieved. This is used by the (not yet commited) backtrace
7501 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7503 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7506 * print.c: Added #include "struct.h". Removed function
7509 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7510 scm_iprin1. Removed prototype for scm_prlist.
7512 * arbiters.c (prinarb),
7513 async.c (print_async),
7514 debug.c (prindebugobj, prinmemoized),
7515 eval.c (prinprom, prinmacro),
7516 filesys.c (scm_fd_print, scm_dir_print),
7518 mallocs.c (prinmalloc),
7519 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7520 smob.h (scm_smobfuns),
7521 srcprop.c (prinsrcprops),
7523 unif.c, unif.h (scm_raprin1, rapr1),
7524 variable.c (prin_var): Changed argument `int writing' to
7525 `scm_print_state *pstate'.
7527 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7528 that it will be called before scm_init_print.
7530 * print.c (scm_prin1): Print states are now allocated when calling
7531 scm_prin1 and then passed around to all printing functions as an
7532 argument. A cache `print_state_pool' enables reuse of print
7534 (scm_make_print_state): New function.
7535 (scm_iprin1): Adaption to print states.
7536 (scm_iprlist): An initial "hare and tortoise" scan brings down
7537 time complexity to O (depth * N). (Better time complexity will be
7538 achieved when the printing code is completely rewritten.)
7540 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7542 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7543 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7544 it gets done whether or not the cache variable has a value.
7546 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7548 Distinguish #f and ().
7549 * __scm.h: #undef SICP.
7550 * pairs.h (SCM_EOL): Delete this definition, equating it with
7552 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7553 the value it used to have. Doc fixes, too.
7555 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7557 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7558 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7559 Lord's implementation of structs, allowing for tail arrays as
7560 described in the manual. Also fixed some bugs. (Both the interface
7561 and the implementation should be improved.)
7563 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7565 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7566 People who whish to see the source can do `(print-enable 'source)'.
7567 Removed #ifdef DEBUG_EXTENSIONS.
7569 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7571 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7572 integer (assuming for now accepting an integer is a good thing).
7574 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7575 %S will be used instead for write'ing arguments.
7577 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7578 asserts. fix a few other asserts.
7579 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7580 scm_uniform_vector_ref, scm_array_set_x,
7581 scm_dimensions_to_unform_array): change args in
7582 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7583 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7584 scm_substring_fill_x): likewise.
7585 gsubr.c (scm_gsubr_apply): likewise.
7586 eval.c (SCM_APPLY): likewise.
7588 * eval.c (4 places): replace scm_everr with lgh_error or
7591 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7592 scm_memory_error): new procedures.
7593 scm_everr: deleted. can use scm_wta, dropping first two args.
7594 scm_error: convert NULL subr to SCM_BOOL_F.
7596 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7599 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7602 * error.c, error.h: new error keys: scm_arg_type_key,
7603 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7605 scm_wta: reimplement using lgh_error instead of scm_everr.
7607 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7609 * gdbint.c: scm_lread now has one more argument.
7611 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7612 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7613 loading source from non-file ports, which, e. g., happens when
7614 using the Emacs interface).
7616 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7619 * read.c: Added code for recording of positions of source code
7620 expressions; New functions: recsexpr, scm_lreadrecparen;
7621 _scm_make_srcprops --> scm_make_srcprops
7622 (scm_flush_ws): Removed updating of positions counters. This work
7623 is already done by scm_gen_getc
7625 * read.h: Added prototype for scm_lreadrecparen
7627 * print.c: Added #include "alist.h"
7629 * eval.c: Added #include "hash.h"
7631 * eq.c: Added #include "ramap.h"

7637 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7638 --> scm_make_srcprops
7640 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7641 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7642 function calls in the definition of the whash access macros.
7644 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7646 * init.c (scm_boot_guile): Add level of indirection to
7647 scm_boot_guile_1() to ensure that stack base pointer is properly
7648 initialized. There was no guarantee that variable i was the
7649 highest/lowest variable on stack (i.e. the call frame of
7650 scm_boot_guile was not completely protected from gc).
7652 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7654 * ports.h (scm_port_table): put back file_name, it will be used to
7655 support debugging. Undo related changes in fports.c, ioext.c,
7658 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7660 * ports.h (scm_port_table): remove file_name member for now, it seems
7662 * fports.c (scm_open_file): don't set file_name in PTAB.
7663 (prinfport): don't use file_name in PTAB.
7664 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7665 * ports.c (scm_add_to_port_table): don't intialize file_name.
7666 (scm_port_file_name): remove for now.
7667 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7669 * fports.h (scm_mkfile): prototype deleted.
7670 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7672 * debug.c, unif.c: use scm_out_of_range instead of
7673 wta for range errors (ASSERT still needs work).
7675 * error.c, error.h (scm_out_of_range): new procedure.
7677 * error.c, error.h (scm_out_of_range_key): new key.
7679 * posix.c (scm_sync): #else was missing.
7681 * error.c, error.h: append _key to names scm_num_overflow and
7684 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7685 of consing an empty list.
7686 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7687 of macros, saves code and string space.
7688 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7689 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7690 lower case. Rename scm_syserror_m to scm_syserror_msg.
7691 error.h: prototypes for new procedures.
7693 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7695 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7697 * error.c, error.h: setup scm_num_overflow key.
7699 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7700 Remove definition of SCM_OVSCM_FLOW.
7702 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7704 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7705 explicit message and args.
7707 * error.c, error.h, __scm.h: change system_error_sym to
7710 * error.c (system_error_sym): remove leading %% from the Scheme name
7713 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7715 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7717 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7718 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7719 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7720 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7721 renamed. (These were introduced by unsupervised name
7724 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7726 * print.c: Added code for detection of circular references during
7727 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7728 a hook for printing of closures (accessible via print options).
7729 This leads to a split of calls to scm_iprin1 into two classes:
7730 elementary print operations (e. g. the code which prints a smob)
7731 still use scm_iprin1 while top level calls (like scm_display) use
7732 scm_prin1. scm_prin1 begins by clearing the data structure used
7733 to record reference information.
7735 * print.h: Added declarations of scm_prin1 and scm_prlist.
7737 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7739 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7741 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7743 * error.c (err_head): scm_iprin1 --> scm_prin1
7745 * debug.c: Adjusted header comment.
7749 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>

7753 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7755 * gdbint.c (gdb_read): Now possible to run during GC.
7756 (unmark_port, remark_port): New functions.
7758 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7760 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7761 of allocating a new string object. Also, increase size by
7762 the factor 2 instead of 1.5.
7764 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7766 * __scm.h (SCM_P): Corrected to run under traditional C.
7768 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7771 * async.c: Calls to scm_sysintern corrected.
7773 * async.h (scm_async_clock): Redundant declaration removed.
7775 * continuations.c (scm_dynthrow): Redundant declaration removed.

7783 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7784 Missing declarations to functions in eval.c added.
7786 * filesys.c: Possibly uninitialized variable rv.
7788 * gc.h (scm_object_addr, scm_unhash_name): Missing
7789 declarations of functions defined in gc.c added.
7791 * genio.c: Possible typos str_data -> wstr_data. ???
7793 * genio.c: Possibly unintended shadowing of local variable
7794 `int c' (gotos out of scope of inner `c'). ???
7796 * init.c: Uninitialized `SCM last' may be used.
7798 * ioext.h: (scm_sys_isatty_p): Typo.
7800 * list.h (scm_list_head): Missing prototype for function in
7803 * numbers.c (scm_two_doubles): Changed from extern to static
7804 (is used only within numbers.c).
7806 * numbers.h: Repeated declarations removed.
7808 * ports.h (scm_close_all_ports_except): Declaration for the
7809 function defined in ports.c added.
7811 * posix.h: Missing declarations added.
7813 * procs.h (scm_make_subr_opt): Missing declaration added.
7815 * socket.h (scm_sys_gethost): Missing declaration added.
7817 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7819 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7820 Missing declarations added.
7822 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7824 * struct.c: Uninitialized variable `SCM answer' may be used.
7826 * unif.c (l2ra): Declaration prototype.
7828 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7829 defined in ramap.c).
7831 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7832 Redundant declarations removed (they are in ramap.h).
7834 * variable.h (scm_make_udvariable,
7835 scm_make_undefined_variable): Declaration corrected to
7836 correspond variable.c.
7838 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7839 Missing declarations added.
7841 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7843 * Makefile.in (distclean): Don't forget to delete fd.h.
7845 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7847 * fd.h.in, tags.h: Trivial cleanups.
7849 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7850 marksweep.h just declared functions from gc.c.
7851 * gc.h, libguile.h: Don't #include "marksweep.h".
7852 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7853 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7854 dependencies updated.
7856 * libguile.h: Don't #include "files.h"; it's been deleted.
7858 * files.c (scm_sys_delete_file): Moved to filesys.c.
7859 File is now empty; deleted.
7861 * filesys.c: scm_sys_delete_file is now here. Remove
7862 #if's; they seem to rely on remnants of an old portability
7863 regimen. If the problems come up again, solve them properly,
7864 using autoconf. Specifically: Don't test M_SYSV, and #define
7865 remove to be unlink if it's #defined; don't use remove just
7866 because HAVE_STDC_HEADERS is #defined.
7867 * filesys.h: Add declarations for scm_sys_delete_file.
7868 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7869 files.o, files.h, files.c, and files.x.
7870 * init.c: Don't #include "files.h", and don't call scm_init_files.
7872 Use SCM_P instead of PROTO; the latter intrudes on the user's
7874 * params.h: Deleted; definition of SCM_P moved to...
7875 * __scm.h: ... here, where it replaces PROTO macro.
7876 * libguile.h, smob.h: Don't #include "params.h".
7877 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7878 smob.h: Fix prototypes accordingly.
7879 * Makefile.in: Update dependencies.
7880 (inner_h_files): Remove params.h.
7882 * gc.c: #include "gc.h"; every module should include its header,
7883 to let the compiler cross-check the declarations against the
7886 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7887 simpos.h: #include "libguile/__scm.h".
7889 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7891 * init.c: Don't forget to #include smob.h and init.h.
7892 * Makefile.in: Dependencies updated.
7894 * smob.h: Use PROTO instead of #if __STDC__.
7896 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7898 * __scm.h: Doc fixes.
7900 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7901 <angles>; this allows `make depends' to work properly.
7903 * libguile.h: #include smob.h and pairs.h before the others; they
7904 define typedefs used by other headers.
7906 C files should #include only the header files they need, not
7907 libguile.h (which #includes all the header files); the pointless
7908 recompilation was wasting my time.
7909 * Makefile.in (all .o dependency lists): Regenerated.
7910 * libguile.h: Don't try to get a definition for size_t here...
7911 * __scm.h: Do it here.
7912 * _scm.h: Since this is the internal libguile header, put things
7913 here that all (or a majority) of the libguile files will want.
7914 Don't #include <libguile.h> here; that generates dependencies on
7915 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7916 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7917 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

8013 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
8014 * weaks.c: Get "weaks.h".
8016 * stackchk.h: #include "libguile/debug.h",
8018 * print.h, read.h: #include "options.h", since everyone who uses
8019 either of these files will need that.
8021 * smob.h: #include "ports.h", "genio.h", and "print.h", since
8022 anyone who uses this file will need them to define the smob
8023 printing functions. Also, get markers.h, since people will need
8024 to #define the mark functions.
8026 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
8027 * ports.h: ... to here.
8029 * ports.h (scm_port_table_size): Explicitly give type as 'int';
8030 don't rely on archaic C default type rules.
8032 * fports.h: #include "libguile/ports.h", since you need that in
8033 order to parse this.
8035 * genio.h: #include "libguile/print.h", because you need that to
8036 parse this; don't bother #including "ports.h", since print.h gets
8039 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
8041 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
8042 this; it's now a reference to an element of *scm_root.
8044 * debug.h: Don't #include "options.h"; the compiler won't be able
8045 to find that once the headers are installed; instead, #include
8046 "libguile/options.h".
8047 * gc.h: Same, with marksweep.h.
8048 * mbstrings.h: Same, with symbols.h.
8049 * scmhob.h: Same, with _scm.h.
8050 * smob.h: Same, with params.h.
8052 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
8053 C files; there's no need for this, and it forces recompilations
8056 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
8058 * error.c (scm_error): declare scm_error_callback.
8060 * error.h: prototype for scm_error_callback.
8062 * __scm.h: define lgh_error.
8063 (SCM_SYSERROR): redefine using lgh_error.
8065 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
8067 * error.c (scm_error): new procedure.
8069 * error.h: prototype for scm_error.
8071 * Makefile.in (install): install scmconfig.h from the current
8072 directory, not $(srcdir).
8074 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8076 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8077 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8078 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
8079 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
8080 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,

8083 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8084 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8085 vports.h, weaks.h: #include "libguile/__scm.h", not
8086 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
8087 dependencies are within libguile properly.
8089 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8091 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8092 when scmconfig.h doesn't exist.
8094 * load.c (scm_sys_try_load): Correct spelling.
8096 * feature.c (scm_loc_features): Make this static.
8098 * Makefile.in (libpath.h): Omit trailing slash from path. We
8099 shouldn't require it of users, so why put it here?
8101 Move code to initialize and search %load-path from ice-9 to C
8102 code, so we can use the load-path to find the ice-9 boot code;
8103 this makes it easier to run Guile without installing it. See
8104 corresponding changes in guile/Makefile.in.
8105 * feature.c: Move stuff concerned with the load path to load.c.
8106 (scm_compiled_library_path): Deleted.
8107 Don't #include libpath.h here.
8108 * feature.h: Don't mention scm_compiled_library_path.
8109 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8110 <sys/stat.h>, and <unistd.h> (if present).
8111 (R_OK): #define if the system hasn't deigned to.
8112 (scm_loc_load_path): New variable.
8113 (scm_init_load_path, scm_sys_search_load_path,
8114 scm_sys_try_load_path): New functions.
8115 (scm_init_load): Initialize scm_loc_load_path to point to the
8116 value cell of the Scheme %load-path variable.
8117 * load.h: Add declarations for scm_sys_search_load_path,
8118 scm_sys_try_load_path.
8119 * init.c: Call scm_init_load_path.
8120 * Makefile.in (feature.o, load.o): Dependencies updated.
8122 * load.c, load.h: Rewrite using PROTO macro.
8124 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8126 * gc.c (scm_cellp): New function: C predicate to determine if an
8127 SCM value can be regarded as a pointer to a cell on the heap.
8129 * gc.h: Added declaration of scm_cellp.
8131 * gdb_interface.h: New file: The GDB interface header from the GDB
8134 * gdbint.c: New file: GDB interface.
8136 * gdbint.h: New file: GDB interface.
8138 * libguile.h: Added #include <libguile/gdbint.h>.
8140 * init.c (scm_boot_guile): Added scm_init_gdbint.
8142 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8143 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8144 found if object files and source are kept separate).
8146 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8148 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8150 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8152 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8153 TK_SRC_DIR; they're not relevant any more.
8155 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8156 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8158 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8160 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8161 search path, so we can find the <libguile/MUMBLE.h> headers.
8163 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8165 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8166 implicit in the .c.o rule.
8167 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8170 Put the library path in a header file, instead of passing it on
8171 the command line in every compilation.
8172 * Makefile.in (libpath.h): New target.
8173 (feature.o): Depend on libpath.h.
8174 (clean): Delete libpath.h.
8175 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8176 * feature.c: ... #include "libpath.h" here.
8177 * .cvsignore: Ignore libpath.h.
8179 Don't install the unwashed masses of Guile header files in the
8180 main #include path; put most of them in a subdirectory called
8181 'libguile'. This avoids naming conflicts between Guile header
8182 files and system header files (of which there were a few).
8183 * Makefile.in (pkgincludedir): Deleted.
8184 (innerincludedir): New variable; this and $(includedir) are enough.
8185 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8186 (installed_h_files): Divide this up. Now this variable lists
8187 those header files which should go into $(includedir) (i.e. appear
8188 directly in the #include path), and ...
8189 (inner_h_files): ... this new variable says which files appear in
8190 a subdirectory, and are referred to as <libguile/mumble.h>.
8191 (h_files): List them both.
8192 (install): Create innerincludedir, not pkgincludedir. Put
8193 the installed_h_files and inner_h_files in their proper places.
8194 (uninstall): Corresponding changes.
8195 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8196 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8197 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8198 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8199 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8200 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8201 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8202 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8203 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8204 vports.h, weaks.h: Find __scm.h in its new location.
8205 * __scm.h: Find scmconfig.h and tags.h in their new locations
8206 (they're both "inner" files).
8208 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8210 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8212 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8214 * posix.c: Doc fixes.
8216 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8218 * socket.c: Don't include a prototype for inet_aton; just use a
8219 K&R style declaration, to avoid warnings but minimize the chance
8220 of conflicts with the system.
8222 On NextStep, <utime.h> doesn't define struct utime, unless we
8223 #define _POSIX_SOURCE before #including it.
8224 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8225 * acconfig.h: New comment text for above CPP symbol.
8226 * configure.in: Call it.
8227 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8229 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8231 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8232 testing for __EMX__.
8234 * posix.c: #include <libc.h>, if it exists.
8236 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8237 don't even know if the latter exists.
8239 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8240 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8241 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8243 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8245 (scm_init_posix): Use them when initializing the Scheme constants
8248 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8250 * Makefile.in (libdir, includedir, bindir): Use the
8251 autoconf-supplied values, instead of deriving them ourselves.
8252 (pkgincludedir, datadir, pkgdatadir): New variables.
8253 (install, uninstall): Put the header files in a special
8254 subdirectory, not in the main search path.
8256 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8257 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8259 * Makefile.in (IMPLPATH): Deleted; never used.
8261 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8262 on the Tcl/Tk source any more.
8263 (INCLUDE_CFLAGS): Remove references to the above.
8265 * Makefile.in (version.o): Corrected dependencies.
8267 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8269 * libguile.h: #include "version.h"
8271 * init.c (scm_boot_guile): Call scm_init_version.
8272 * gscm.c (gscm_run_scm): Call scm_init_version.
8274 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8275 GUILE_VERSION): AC_DEFINE these.
8276 (acconfig.h): #undef the above symbols.
8278 * Makefile.in (libobjs): Add version.o.
8279 (installed_h_files): Add version.h.
8280 (c_files): Add version.c.
8281 (gen_c_files): Add version.x.
8282 (version.o): New rule.
8283 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8284 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
8285 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
8286 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,

8292 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
8293 weaks.o): Add version.h to dependency lists.
8294 (markers.o): Remove duplicate rule.
8296 * version.h: New file.
8298 * version.c: New file.
8300 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8302 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8303 array; use it appropriately. Since GCC is quite happy to
8304 subscript functions, it never warned us about this; we should use
8305 -Wpointer-arith in the future. I guess we never tested
8308 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8310 * socket.c: Doc and copyright fixes.
8312 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8314 * debug.c: Fixed and improved gdb support.
8316 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8318 * socket.c: Added declaration of inet_aton to avoid compiler
8319 warning. (Hope this solution is correct.)
8321 * stime.c: Added declaration of ftime. (This is missing in
8324 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8326 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8328 * Makefile.in (c_files): add strerror.c.
8330 * strerror.c: new file from Emacs' sysdep.c.
8331 maybe configure should also check for sys_errlist.
8333 * configure.in (AC_REPLACE_FUNCS): add strerror.
8335 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8337 * debug.c (scm_init_debug): Added initialization for
8338 scm_evaluator_traps.
8340 * debug.h, debug.c: Various name changes.
8341 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8342 "debug-options-interface". See commentary in options.c.
8344 * options.h, options.c: Options now have documentation strings.
8345 Also added a long explanatory commentary.
8347 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8350 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8351 last_debug_info_frame is now updated in all cases.
8353 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8356 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8358 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8359 Added option STACK_CHECKING.
8361 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8363 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8365 * __scm.h: Removed symbols for debugging support.
8367 * acconfig.h: Added symbols for debugging support.
8369 * configure.in: Added user option for debugging support.
8370 --enable-debug will include the debugging code into libguile.a.
8372 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8373 scm_relocate_chunk_to_heap.
8375 * debug.c: New file: low-level debugging support. It also
8376 includes support for debugging with gdb. (The extensions to gdb
8377 are written by Per Bothner at Cygnus.)
8379 * debug.h: New file: low-level debugging support.
8381 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8382 argument pairs. Extensive modifications to the debugging
8383 evaluator. Added "SECTION:" commentaries to clarify what happens
8384 when, during double compilation. Renamed EVALIMP --> EVALIM.
8385 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8386 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8387 the beginning of the file. New procedure: scm_unmemocopy.
8388 Added some global state variables needed by the debugging
8389 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8390 check_entry, check_apply, check_exit, debug_options and
8391 evaluator_traps. New acro: undefine.
8393 * eval.h: Renamed EVAL --> XEVAL.
8395 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8396 --> scm_make_weak_key_hash_table.
8398 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8399 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8401 * libguile.h: Conditionally include debug.h
8403 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8404 scm_object_properties shouldn't return handle. `handle' now gets
8405 initialized in scm_set_object_properties_x. scm_object_properties
8406 doesn't any longer create an entry in scm_object_whash.
8408 * options.c: New file: handling of run time options.
8410 * options.h: New file: handling of run time options.
8412 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
8414 * print.c: New procedure: scm_print_options
8416 * print.h: Defines for print options.
8418 * read.c: New procedure: scm_read_options
8420 * read.h: Defines for reader options.
8422 * root.h: Added scm_source_whash among scm_sys_protects.
8424 * srcprop.c: New file: source properties.
8426 * srcprop.h: New file: source properties.
8428 * throw.c (jbsmob): Jump buffers are now correctly allocated.
8429 (Bug found by A. Green.)
8431 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8433 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8435 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8437 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8439 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8440 and should be called by the final client.
8442 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8444 * gc.h: Use the PROTO macro when declaring functions.
8445 * gc.c: Use the PROTO macro when declaring static functions.
8446 Remove the CPP hair around function definitions.
8448 * gc.c (scm_init_storage): Initialize scm_asyncs.
8450 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8451 preprocessor symbol; "__scm.h" is where it might get #defined.
8452 * __scm.h: Similar: #include <scmconfig.h> before testing
8455 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8457 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8459 * init.c (scm_boot_guile): Add init_func argument; call
8460 (*init_func) instead of calling scm_appinit; it's ucky to
8461 hard-code names for the user's procedures.
8462 * init.h (scm_boot_guile): Adjust declaration.
8464 * __scm.h (PROTO): New macro, for declaring functions with
8467 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8468 eliminate all the __STDC__ conditionals.
8469 (scm_boot_guile): Add declaration.
8470 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8471 Remove __STDC__ conditionals around function definitions; the
8472 declarations in init.h will provide the same information, more
8475 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8476 complain about it in the error message; the error message is
8477 adequate without that note, and there's nothing the user can do
8480 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8482 * Makefile.in (ancillary): Drop def.sed.
8484 * posix.c (scm_init_posix): Use numeric values, rather than
8485 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8486 F_OK. The symbols aren't available on some systems, and I'm
8487 pretty sure their values are fixed by common widespread practice.
8488 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8490 More functions unavailable on some systems.
8491 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8492 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8494 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8495 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8496 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8497 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8498 stub that signals an error as the #else.
8500 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8502 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8504 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8506 * unif.c: include ramap.h.
8508 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8510 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8512 * ports.c: include sys/ioctl.h.
8514 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8516 * configure.in: check for sys/ioctl.h.
8518 * ports.c: include <malloc.h> not "malloc.h".
8520 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8522 * fports.c: remove ttyname and tmpnam declarations.
8524 * posix.c: fewer ttyname declarations.
8526 * fports.c: include <string.h> not "string.h".
8528 * init.c, ioext.c: include string.h and unistd.h.
8530 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8532 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8533 genio.c, simpos.c, vports.c: include string.h.
8535 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8537 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8539 (scm_addr_buffer_size): change type from scm_sizet to int.
8540 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8541 from scm_sizet to int.
8543 * error.c: include unistd.h.
8545 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8548 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8550 * __scm.hd, def.sed: deleted.
8552 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8554 Changes for NeXT, suggested by Robert Brown.
8555 * configure.in: Call AC_TYPE_MODE_T.
8556 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8557 NeXT. Put header file list in alphabetical order.
8558 * configure, scmconfig.h.in: Regenerated.
8559 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8561 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8564 * acconfig.h: New file, providing documentation for the CPP
8565 symbols defined in configure.in
8566 * acconfig-1.5.h: Removed; superceded by the above.
8568 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8570 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8572 * fports.c (scm_open_file): don't return #f, throw error.
8574 * ioext.c (fileno): renamed from %fileno.
8575 (soft-fileno): deleted.
8577 * ports.c (scm_port_revealed): don't need to check for -1 from
8579 (scm_set_port_revealed_x): return unspecified, not #f.
8581 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8583 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8585 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8587 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8589 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8591 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8592 This is necessary on Ultrix, and doesn't hurt portability.
8594 * Makefile.in (dist-dir): New target, implementing a new dist system.
8595 (installed_h_files): Put in alphabetical order.
8596 Remove duplicate entries for markers.h and unif.h.
8597 (c_files): Remove duplicate entries for markers.c.
8598 (ancillary): Renamed from anillery; all uses changed. Remove
8599 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8600 Remove all the ../doc/* files; doc/Makefile.in handles that.
8602 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8604 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8605 every if must have an else, or else the whole command has a
8606 non-zero exit code whenever the if's condition is false.
8608 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8610 * posix.c: include string.h.
8612 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8614 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8617 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8618 Remove leading % from scheme names.
8619 Do not return error values, call SCM_SYSERROR or similar.
8621 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8623 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8625 * struct.c (scm_init_struct): new file.
8627 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8629 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8630 (scm_list_head): added list-head for rapidly chopping argument
8631 lists off of longer lists (and similar).
8633 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
8635 * objprop.c (scm_object_property): assq the cdr of the whash
8636 handle for obj, not the handle itself.
8638 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8640 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8641 weak hash tables last of all marking to avoid an obscure gc bug.
8642 WARNING: circular lists stored in a weak hash table will hose us.
8644 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8646 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8647 new functions similar to scm_substring_move_left_x and
8648 scm_substring_move_right_x.
8650 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8652 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8655 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8657 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8659 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8661 * strports.c (scm_strprint_obj): convenience function. C for
8662 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8664 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8665 removed to a separate library
8667 * init.c (scm_boot_guile): copied from guile-tcl.c.
8668 Initialization specific to tcl interpreters removed.
8670 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8672 * ports.c (scm_ports_prehistory): size malloced here doesn't
8673 matter so long as it is non-0 (got rid of "* 4").
8675 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8677 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8678 since its definition was bogus).
8680 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8682 * mallocs.[ch]: back again (for rx at least).
8684 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8686 * ports.c: removed functions relating to the mapping between ports
8687 and descriptors. (That stuff is unix-specific and should be collected
8688 in a separate library).
8690 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8691 (Tom Mckay@avanticorp.com)
8693 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8695 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8696 handled correctly (SCM_FREEP was applied to them) -- test for
8697 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
8698 being overwritten with #f. (brown@grettir.bibliotech.com)
8700 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
8702 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
8703 for a specific symbol or for all symbols.
8705 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
8707 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
8708 keys and weak values confused).
8710 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
8712 * list.c (scm_last_pair): map '()=>'()
8714 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
8716 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
8717 Generalized assoc and hash-table functions.
8718 Factored pairs.c into multiple files.
8720 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
8722 * gscm.c (gscm_run_scm): got rid of objprop.
8724 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
8726 * genio.c (scm_getc):
8727 NOTE: fgetc may not be interruptable.
8729 * procprop.c (scm_stand_in_scm_proc):
8730 NOTE: don't use a alist here.
8731 (scm_set_procedure_properties_x): fix type checking throughout this file.
8733 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
8735 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
8736 after freeing part of the port table.
8738 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
8740 * strports.c (scm_mkstrport):
8741 * vports.c (scm_make_soft_port): allocate a port table entry
8742 (possibly triggering gc) before setting the tag of the corresponding
8745 * pairs.c (scm_delq_x): never throw an error.
8747 * vectors.c (scm_make_vector): made the default vector fill argument
8748 into '() (much more useful than the previous value, "#unspecified")
8750 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
8752 * ports.c (scm_add_to_port_table): Added fields
8753 to port table entries: file_name, line_num, col.
8754 Update these in open_file, gen_getc and gen_ungetc.
8755 Added procedures to access those fields.
8757 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
8759 * procs.c (scm_make_subr_opt): new entry point for making
8762 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
8764 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
8766 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
8768 * numbers.c (scm_exact_p): This function no longer
8769 implements "integer?".
8771 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
8773 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
8774 (scm_gc_stats): return an assoc of useful data. Replaces "room"
8775 and the stats reporting formerlly built into repl.
8777 * repl.[ch]: removed.

8798 NOTE: this should throw a resumable exception with parameters --
8799 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
8801 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.

8865 initialization to fix a race condition.
8867 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

8891 set the multi_byte flag correctly in symbols. This is wrong.
8892 intern_obbary_soft and msymbolize should take an extra parameter.
8893 Also, weird multibyte symbols don't print correctly.
8894 The weird symbol syntax is also a bit bogus (emacs doesn't quite
8897 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
