1 1999-09-21 Jim Blandy <jimb@savonarola.red-bean.com>
3 * backtrace.c: #include "_scm.h" before testing whether
4 HAVE_UNISTD_H is #defined.
6 1999-09-20 Jim Blandy <jimb@savonarola.red-bean.com>
8 * read.c (scm_read): Don't assume that scm_cur_inp is always open.
9 * ports.c (scm_read_char): Same.
10 * ioext.c (scm_read_line): Same.
11 (Thanks to Bernard Urban.)
13 1999-09-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
15 * vectors.c (scm_vector_move_right_x): Bugfix: Remove side effect
17 numbers.c: Removed #ifndef SCM_RECKLESS at places where type
18 checking may invoke a generic. (Thanks to Michael Livshin.)
20 * __scm.h (SCM_WTA_DISPATCH_0, SCM_GASSERT0): New macros.
22 * numbers.c (scm_max, scm_min, scm_sum, scm_difference,
23 scm_product, scm_divide): Bugfix: Don't pass SCM_UNDEFINED to the
24 generic function if the asubr is called with only one arg.
26 1999-09-20 Gary Houston <ghouston@freewire.co.uk>
28 * scmsigs.c (scm_sigaction): add SA_RESTART to flags only if
29 HAVE_RESTARTABLE_SYSCALLS.
30 (scm_init_scmsigs): use siginterrupt if it's available. not
31 everyone who has restartable syscalls has SA_RESTART it seems.
33 (scm_sigaction): use scm_num2long/scm_long2num when converting
34 SIG_DFL/SIG_IGN, in case it doesn't fit in an INUM. use
35 scm_integer_p to test the type.
37 1999-09-18 Gary Houston <ghouston@freewire.co.uk>
39 * _scm.h, scmsigs.c: replace HAVE_RESTARTS with
40 HAVE_RESTARTABLE_SYSCALLS.
42 * strports.c (scm_strport_to_string): create the string from
43 pt->read_buf instead of an expression that evaluates to the
46 * gdbint.c (gdb_print): don't just use SCM_CHARS to get a C string
47 from the port: the port's buffer may not be NUL terminated.
49 1999-09-16 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
51 * Makefile.am (.c.x): Added missing semicolon after `false'.
53 1999-09-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
55 * print.c (scm_iprin1): Turn `write' and `display' into
56 primitive generics and use their associated generic functions in
57 scm_iprin1 for GOOPS objects.
59 * backtrace.c: #include <unistd.h> if present.
61 1999-09-14 Jim Blandy <jimb@savonarola.red-bean.com>
63 * Makefile.am (.c.x): Don't create a subshell just to delete the
64 .x file and return false.
65 * Makefile.in: Regenerated.
67 1999-09-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
69 * feature.c (scm_create_hook): New function. Replaces
70 scm_make_named_hook which is now deprecated.
71 (scm_make_hook_with_name): New primitive.
72 (print_hook): Hooks now print in a fancy way.
74 1999-09-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
76 * __scm.h, backtrace.c, backtrace.h, debug.c, debug.h, dynl-dld.c,
77 dynwind.c, dynwind.h, eval.h, evalext.c, evalext.h, feature.c,
78 feature.h, hashtab.c, hashtab.h, objects.c, objects.h, print.c,
79 procs.c, procs.h, smob.c, smob.h, srcprop.c, strorder.c, struct.c,
80 struct.h: Updated copyright notices.
82 * srcprop.c (scm_source_property): Bugfix: Use SCM_NECONSP instead
83 of SCM_NCONSP. (Thanks to Greg Badros.)
85 * gsubr.c (scm_make_gsubr): Use scm_make_subr_opt for creation of
88 * eval.c, debug.h (SCM_BACKTRACE_WIDTH): New debug option: width.
90 * backtrace.c: Keep backtraces within specified width by
91 adaptively adjusting fancy printing parameters and cut output if
93 (scm_display_application): Check args.
95 1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
97 Change the name of the objects returned by OPENDIR from
98 "directory" to "directory stream". A predicate named "directory?"
100 * filesys.c (scm_directory_stream_p): Renamed from scm_directory_p.
101 At the Scheme level, "directory?" -> "directory-stream?".
102 (scm_dir_print): Use the phrase "directory stream" in printed form.
103 * filesys.h (scm_directory_stream_p): Prototype renamed
106 * Makefile.am (CLEANFILES): Remove versiondat.h; that should only
107 be removed by `make distclean', since it's generated by configure.
108 * Makefile.in: Regenerated.
109 (Thanks to Robert Bihlmeyer.)
111 * strop.c (scm_substring_move_x): Signal an error if start1
112 doesn't come before end1. (Thanks to Karoly Lorentey).
114 * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
115 calling SCM_NIMP. (Thanks to Karoly Lorentey).
117 * version.c (scm_libguile_config_stamp): Deleted. See
118 corresponding change to ../ice-9/boot-9.scm.
119 * versiondat.h.in: Remove definition for GUILE_STAMP.
120 * version.h: Delete prototype.
121 * Makefile.in: Regenerated.
123 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
125 * filesys.c (scm_directory_p): new procedure "directory?" Returns
126 a boolean indicating whether its argument is a directory
127 port as returned by opendir (thanks to Dirk Herrmann for the
130 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
132 * backtrace.c (display_frame_expr): Don't print a newline.
133 (display_frame): Print the newline here instead.
134 (display_backtrace_body): Don't print "Backtrace:".
135 (scm_backtrace): Print "Backtrace:" here instead.
137 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
139 * procs.c (scm_setter): Signal WTA if handed an entity or operator
142 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
143 primitives. (Thanks to Greg Badros);
144 (scm_hook_to_list): New primitive; Hooks are now smobs.
146 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
148 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
149 of #f for the 10th vector element to avoid an exception
150 seen by Bernard Urban.
151 (scm_mktime): unneeded ASSERT removed.
153 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
155 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
158 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
160 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
162 * numbers.c: Converted comparison operations to dispatch on
163 generic if args don't match.
165 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
167 1999-09-06 James Blandy <jimb@mule.m17n.org>
169 * guile-snarf.c: Deleted. Snarfing should respect CPP
170 conditionals, so it needs to actually run CPP. Bleah.
172 1999-09-05 James Blandy <jimb@mule.m17n.org>
174 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
175 * guile-snarf.in: Be sure to exit with an error if CPP does.
176 * Makefile.am (.c.x): Delete the .x file and exit with an error
177 status if guile-snarf exits with an error status.
178 * Makefile.in: Regenerated.
180 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
181 scm_makekey, which doesn't exist any more. Guess nobody's using
184 * guile-snarf.c: New implementation of guile-snarf, meant to be
185 more robust than the shell script. I think it's complete, but I
186 haven't tested it at all, and I haven't changed the build process
187 to actually use it. We should compare its output against that of
188 the existing shell script, for all source files.
190 * guile-snarf.c (parse_args): Abort if we haven't handled some
193 1999-09-03 James Blandy <jimb@mule.m17n.org>
195 * load.c (scm_search_path): If the filename has any extension at
196 all, ignore the entire list of extensions. Also, don't check whether
197 the file is accessible. If the file exists, accessible or not, we
198 should return it. Inaccessible files should cause an error later.
199 (Thanks to Keisuke Nishida for the suggestions.)
201 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
203 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
204 atexit not available. (sunos4.1.4 needs it.)
206 1999-09-01 James Blandy <jimb@mule.m17n.org>
208 I take it all back --- bcopy does handle overlapping source and
209 destination areas correctly. At least on every system I could
210 find. But it is better to use AC_REPLACE_FUNCS than to introduce
211 new CPP conditionals.
212 * memmove.c: New file, implementing memmove in terms of bcopy.
213 * scmconfig.h.in: Regenerated.
215 Allocators should use the `void *' type for generic pointers.
216 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
217 argument and return types.
218 * gc.h: Corresponding changes to prototypes.
221 1999-08-31 James Blandy <jimb@mule.m17n.org>
223 * numbers.c (scm_init_numbers): Claim to support the `complex'
224 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
226 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
227 find (ice-9 boot-9) when Guile was compiled in a separate
228 directory from the source. (Thanks to Rodney Brown.)
229 * Makefile.in: Regenerated.
231 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
232 table lengths by the size of a single element when growing the
233 table. (Thanks to Bill Schottstaedt.)
235 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
237 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
238 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
239 since that cuts down the time for type dispatch by 50%.
241 1999-08-30 James Blandy <jimb@mule.m17n.org>
243 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
244 not a correct substitute for memmove, because it doesn't handle
245 overlapping source and destination areas on many platforms.
246 Overlaps are the primary reason to use memmove in the first place.
247 * ports.c (scm_ungetc): Same.
248 * strop.c (scm_substring_move_x): Same.
250 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
252 * gc.c (scm_init_storage): Skip registration of cleanup on systems
253 which lack atexit. (Is it important that cleanup is made
254 properly? Maybe we should replace all `exit' with `scm_exit' and
257 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
258 scm_struct_free_standard, scm_struct_free_entity): Declared to
259 return scm_sizet instead of size_t.
261 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
262 there on sunos4.1.4.)
264 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
266 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
267 Account for the case when second argument is unbound.
269 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
270 (Thanks to Karoly Lorentey.)
272 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
273 isn't present. (Thanks to Suzuki Toshiya.)
275 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
278 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
281 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
282 Bernard Urban and Ian Grant.)
284 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
285 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
286 change in the representation of entities and operators.)
288 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
290 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
291 don't allocate zero bytes (thanks to Bill Schottstaedt).
293 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
295 * procs.c (scm_setter): Converted to use generic dispatch.
297 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
300 * load.c (scm_search_path): Don't try extensions which already are
301 present at the end of the filename.
302 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
304 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
306 Cleanup and simplification of generic method dispatch.
307 Also, the quadruple representation of entity and operator
308 procedures has been replaced with single.
310 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
312 * print.c (scm_isymnames): Removed #@hash-dispatch.
314 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
315 from eval.c; Support 0 arity methods.
316 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
317 (scm_apply_generic_env): Removed.
318 Replaced slots proc0-3 with procedure.
320 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
321 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
322 SCM_OPERATOR_PROCEDURE.
323 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
324 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
326 * struct.c, struct.h: Replace 4 procedure slots with one.
327 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
329 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
332 * eval.c (scm_sym_args): Removed.
333 (SCM_CEVAL): Simplified entity application.
334 Moved dispatch code to objects.c.
336 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
338 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
340 * sort.c (closureless): Use scm_eval_body.
342 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
343 with a symbol as last form was first called normally and then via
344 `map' or some other mechanism using primitive apply, an ILOC was
347 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
349 This change extends the representation of primitive procedures
350 with more data fields, e.g. a place for documentation and true
351 procedure properties.
353 * procs.c, procs.h (scm_subr_entry): New type: Stores data
354 associated with subrs.
355 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
356 SCM_SUBR_DOC): New macros.
357 (scm_subr_table): New variable.
358 (scm_mark_subr_table): New function.
360 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
362 * gc.c (scm_gc_mark): Don't mark subr names here.
363 (scm_igc): Call scm_mark_subr_table.
366 This change implements a scheme for letting a generic work as a
367 shadow for a primitive procedure. If the primitive procedure
368 can't dispatch on its arguments, control is left over to the
369 generic. Normal wrong type arg errors will be generated until the
370 user has hung the first method on the primitive.
372 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
374 * procs.c, procs.h (scm_subr_p): New function (used internally).
376 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
378 * objects.c, objects.h (scm_primitive_generic): New class.
380 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
382 * print.c (scm_iprin1): Print primitive-generics.
384 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
385 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
387 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
388 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
389 primitives). NOTE: This means that it is now *required* to use
390 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
391 obscured representation that will be removed in the future anyway,
392 so backward compatibility is no problem here).
394 * numbers.c: Converted most numeric primitives (all but bit
395 comparison operations and bit operations) to dispatch on generic
399 Better support for applying generic functions.
401 * eval.c, eval.h (scm_eval_body): New function.
403 * objects.c (scm_call_generic_0, scm_call_generic_1,
404 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
408 Optimization of the generic function dispatch mechanism.
410 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
411 called scm_memoize_method instead of doing a second lookup.
413 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
418 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
419 scm_sysintern so that the binding connected with the subr name
420 isn't cleared when we give set = 0.
423 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
425 More transparent handling of ports with print states.
427 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
428 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
429 instead of a pair of a port and a print state. We'll need to cons
430 once extra in scm_printer_apply but the type system will be
431 cleaner, it will mix better with GOOPS, and, it will be even more
432 transparent to the user.
434 * print.c (scm_get_print_state): New procedure: Given an output
435 port, return the print state associated to it in the current print
436 chain, if one exists;
437 (scm_port_with_print_state): New procedure: Associate a
438 print-state with a port.
439 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
440 (scm_printer_apply): Wrap port and pstate as a smob;
441 (print_state_printer): Removed.
443 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
445 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
448 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
449 testing (otherwise the port-print-state trick won't be transparent
450 to the user; one example where this caused problems was in the
451 (ice-9 format) module).
453 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
455 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
456 SCM_UNSPECIFIED instead of the set value.
458 1999-08-20 James Blandy <jimb@mule.m17n.org>
460 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
462 * ports.h (enum scm_port_rw_active): New enum, containing
463 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
464 zero). The debugger knows about enums, but doesn't know about
466 (typedef scm_port): Declare rw_active member to be an enum
468 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
470 * ports.c (scm_add_to_port_table): Same.
471 * strports.c (st_flush, st_end_input): Same.
473 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
474 scm_must_realloc, and scm_done_malloc as appropriate.
476 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
478 * sort.c (quicksort): Added condition to protect the algorithm
479 from crashing the interpreter if the less predicate is buggy.
481 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
483 * fports.c (fport_write): fix line-buffering mode again.
484 (scm_open_file): recognise 'l' for line-buffering.
485 (scm_setvbuf): recognise _IOLBF for line-buffering.
487 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
489 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
492 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
495 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
497 * fports.c (fport_write): use memcpy instead of strncpy, in case
498 the data contains NUL.
500 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
502 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
504 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
505 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
506 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
507 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
508 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
509 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
510 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
511 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
512 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
513 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
514 scm_sym_ as prefix for symbols.
516 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
518 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
519 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
520 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
521 scm_sym_atcall_cc): Made global.
523 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
525 * eval.c (scm_sym_args): Made global.
527 * objects.c (scm_set_object_procedure_x): Disallow setting of
528 procedures for pure generic functions.
530 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
532 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
533 Scheme name from lseek to seek, but lseek was added recently so
534 it shouldn't be a big problem.
535 * ports.c, gdbint.c, ioext.c: changed callers.
537 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
539 * fports.c (fport_input_waiting): if select is used, return 1
540 instead of whatever FD_ISSET expands to. maybe it will be useful
541 to interpret the value from the input_waiting ptob procedure as a
542 lower bound on the number of bytes available.
544 * Mikael asked for a few names to be changed...
546 * ports.c (scm_make_port_type): take the write procedure as the
547 second argument instead of the flush procedure.
548 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
549 fflush -> flush, read_flush -> end_input, fclose -> close,
550 fill_buffer -> fill_input, ftruncate -> truncate,
551 input_waiting_p -> input_waiting.
553 * ports.c (end_input_void_port): was read_flush_void_port.
554 (scm_set_port_end_input): was scm_set_port_flush_input.
555 (scm_set_port_flush): was scm_set_port_write.
556 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
557 (scm_end_input): was scm_read_flush.
558 (scm_fill_input): was scm_fill_buffer.
559 (scm_flush): was scm_fflush.
560 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
561 (fport_end_input): was local_read_flush.
562 (fport_flush): was local_fflush.
563 (fport_close): was local_fclose.
564 (fport_truncate): was local_ftruncate.
565 (fport_seek): was local_seek.
566 (fport_free): was local_free.
567 (fport_fill_input): was fport_fill_buffer.
568 * strports.c (st_end_input): was st_read_flush.
569 (st_truncate): was st_ftruncate.
570 * vports.c: (sf_flush): was sfflush.
571 (sf_close): was sfclose.
572 (sf_fill_input): was sf_fill_buffer.
574 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
577 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
579 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
580 forms now contain the expressions to be dispatched upon instead of
581 depending on a surrounding lambda or let; Generic function
582 dispatch has been optimized; `apply' on a generic function now
583 works a little bit strangely. It uses a trick so that the type
584 dispatch code in SCM_CEVAL can be reused.
586 * objects.h, objects.c (scm_apply_generic_env): Added (used by
588 (scm_operator_p): Added.
589 (scm_sym_atdispatch): Added.
590 (scm_set_object_procedure_x): Modified to handle the new style
592 (scm_object_procedures): New debugging procedure.
594 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
596 * eval.c, eval.h (scm_sym_args): Added.
598 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
600 * feature.c, feature.h (scm_c_run_hook): Added.
602 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
603 cdrxnoap and loopnoap instead of begin and loop.
605 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
607 * ports.c (scm_putc, scm_puts),
608 * unif.c (scm_uniform_array_write): use scm_lfwrite.
609 * ports.c (scm_putc): change type of first argument from int to char.
611 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
613 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
614 SCM_IM_HASH_DISPATCH.
616 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
617 (scm_si_redfined, scm_si_hashsets): Moved.
619 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
620 flag which combines type and status info so that the class
621 redefinition protocol has zero cost during normal execution.
623 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
625 * ports.h (scm_ptob_descriptor): include a write procedure again.
626 it's more efficient for unbuffered fports (e.g., sockets.)
628 * ports.c (scm_puts): use ptob->write.
629 * vports.c (scm_make_sfptob): set write proc in ptob.
630 * strports.c (scm_make_stptob): set write proc in ptob.
631 * ports.c (write_void_port): new procedure.
632 * vports.c (sf_write): new procedure.
633 * ports.c (scm_lfwrite): use ptob->write.
634 * strports.c (st_write): new procedure.
635 * fports.c (fport_write): new procedure.
636 (scm_make_fptob): set write in ptob to fport_write.
637 * ports.h: prototype for scm_set_port_write.
638 * ports.c (scm_make_port_type): initialise ptob write procedure.
639 (scm_set_port_write): new proc.
641 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
643 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
644 until we've verified that it is actually a port. (Thanks to
647 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
649 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
650 code, particularly an unnecessary test (len != size, where len ==
651 size). (Was this leftovers from debugging code, or have I missed
654 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
655 size. (Thanks to James Dean Palmer.)
657 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
658 (Thanks to Lorentey Karoly.)
660 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
662 * eval.c (scm_m_expand_body): Use scm_cons_source.
664 * struct.c (scm_print_struct): Use vtable name.
666 * print.c (scm_init_print): Set name of print state type.
668 * stacks.c (scm_init_stacks): Set name of stack type.
670 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
672 * eval.c (SCM_CEVAL): Removed old implementation of internal
675 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
677 * debug.c, debug.h (scm_reverse_lookup): Added.
678 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
679 internal procedure definitions; Don't use scm_i_inner_name.
681 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
684 * eval.h: Added prototypes for multi language support functions.
686 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
687 improper lists in the low-level representation, since that will
688 cause a begin to be prepended at macro expansion.
690 * eval.c (scm_cons_source): Version of cons which copies source
691 properties from an existing cell.
692 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
694 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
695 procedure source before calling scm_unmemocopy instead of faking
698 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
700 Ported `internal defines' fix from SCM. Original ChangeLog entry:
702 1998-07-09 Radey Shouman <radey@colorage.com>
704 * eval.c (ceval_1): Modifications to allow rewriting of interal
705 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
706 body of which it is the CAR is macro expanded by m_expand_body,
707 which rewrites internal DEFINE.
709 (m_expand_body): Added.
711 (m_macroexp1): Added argument to control error checking:
712 m_expand_body may speculatively expand forms in the wrong
713 environments. Made argument number checks conditional on
716 (m_body): Added, error checks bodies and inserts the ISYM tokens.
718 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
721 (m_cond): (m_case): (m_quote): Modified to avoid destructively
722 changing their argument forms. Since m_expand_body
723 speculatively macro expands forms the process must be
726 (m_ident_eqp): Fixed to use proper environment.
728 (renamed_ident): Added DEFER_INTS_EGC.
730 Added prototypes for static functions.
736 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
737 is false, do not produce an error for unbound variables, return a
738 pointer to cell_undef instead.
740 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
744 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
745 destructively changing their argument forms. Since m_expand_body
746 speculatively macro expands forms the process must be reversible.
748 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
749 SCM_IM_LET introduced by named lets.
751 (scm_m_letstar): Use scm_m_body instead of bodycheck.
753 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
754 scm_letrec. scm_letrec1 does not check for a null binding and
755 takes an additional argument to specify the ISYM of the body. Use
756 scm_m_body instead of bodycheck.
758 (scm_m_let): Use scm_m_body instead of bodycheck.
760 (scm_m_expand_body, scm_macroexp): New.
762 (unmemocopy): Account for ISYMs introduced by scm_m_body.
764 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
765 check=1. Throw error for internal defined that have not been
766 rewritten by scm_m_expand_body.
768 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
769 Removed prototype for SCM_APPLY.
771 * tags.h: Added extern declaration of scm_isymnames.
773 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
775 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
777 * lang.c: New file: Beginning of multi-language support.
779 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
781 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
782 (scm_dynamic_wind): Added argument checking for the after guard so
783 that we don't add garbage on the dynwind chain.
784 (scm_swap_bindings): Added.
786 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
787 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
788 (scm_isymnames): New isyms for multi-language support.
790 * eval.c (scm_nil, scm_t): New symbols.
791 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
792 forms for multi-language support.
794 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
796 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
798 Renamed functions in the random function library interface
799 from scm_i_XXX --> scm_c_XXX.
801 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
803 * ports.c (scm_putc): fix line-buffering.
805 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
807 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
808 scm_set_ptob_XXX --> scm_set_port_XXX.
810 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
812 * ports.c, ports.h (scm_make_port_type): New interface for
813 creation of port types (replaces scm_newptob). Just as for the
814 smobs, we need to separate the internal representation of smob
815 types from the interface, so that we easily can add new fields and
816 rearrange things without caring about backward compatibility.
817 This change was forced by the need in GOOPS to create classes
818 representing port types.
819 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
820 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
821 scm_set_ptob_seek, scm_set_ptob_truncate,
822 scm_set_ptob_input_waiting_p): New setters.
823 (scm_newptob): Rewritten to use scm_make_port_type. For backward
825 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
826 (scm_prinport): Removed.
827 (scm_port_print): Added.
828 (scm_print_port_mode): Added.
829 (void_port_ptob, print_void_port, close_void_port, noop0):
830 Removed. Removed #include "genio.h" Added #include "objects.h",
833 * fports.c (prinfport): Moved code from ports.c.
835 (scm_fptob): Removed. Instead use new interface.
836 (scm_make_fptob): Added. (Need to create basic ports in a
837 specific order in ports.c.)
839 * strports.c (scm_stptob, prinstpt, noop0): Removed
840 (scm_make_stptob): Added.
842 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
843 (scm_make_sfport): Added.
845 * filesys.c (scm_dir_print): Don't use the port printing code.
846 Instead provide specific directory printer.
848 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
850 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
853 * smob.c (scm_smob_print): Handle non-existing type name nicely.
854 Removed #include "genio.h"
856 * objects.c (scm_make_port_classes): New function ptr.
858 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
860 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
862 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
863 allow the 1st argument to be a fdes or filename as well as a
864 port (as in the filesys.c version).
866 * filesys.c (scm_truncate_file): removed.
868 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
870 * readline.c, readline.h: Removed.
872 * objects.c, objects.h (scm_port_class): Added.
873 (scm_class_of): Look up port class in scm_port_class.
874 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
875 SCM_INOUT_PCLASS_INDEX): Added.
878 * Makefile.am: Removed genio.c, genio.x.
882 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
884 * init.c: Make sure that scm_post_boot_init_modules is called only
885 once. (Important when using a dumped image.; Thanks to Bernard
888 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
890 * guardians.c (scm_guardian_zombify): Separate scanning for
891 zombies from marking the pairs of the free list.
893 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
894 use the macros. (Thanks to Michael Livshin.)
896 * eval.c (scm_m_lambda): Let bodycheck check the body of the
897 lambda. Let your sins be purified by the blood of the lambda.
898 (Thanks to Eric Hanchrow.)
900 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
901 (Thanks to Valdis Kletnieks.)
903 Fixes for EMX from Mikael Ståldal.
905 * filesys.c: #include <io.h>, if we have it.
906 * scmconfig.h.in: Regenerated.
908 * stime.c (ftime): Delete declaration for this function --- let
909 the system supply it.
911 Cleanups from John Bley.
913 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
915 * gsubr.c: Don't include "gsubr.h" twice.
917 Cleanups for compilation on Irix 6, from David Kaelbling.
919 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
920 regex_t pointer. This is what the callers have, mostly.
921 (scm_regexp_exec): Don't forget to pass the `rx' argument to
922 scm_regexp_error_msg.
924 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
925 int. That way, if we get a warning on this line, it's more likely
926 that we're really missing bits we care about.
928 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
931 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
932 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
933 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
934 cast at all is more appropriate in every case. At the moment, we
935 assume everywhere that SCM is an integral type anyway.
937 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
939 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
940 read_pos after scm_fill_buffer.
942 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
945 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
946 fports.c (fport_fill_buffer): implement the interface change.
948 * ports.c (scm_fill_buffer): interface change: no longer increments
949 read_pos past the character that's returned. it seems clearer to
950 leave it to the caller to decide what to do (thanks Jim).
952 * vports.c (sf_fill_buffer): put the read char into the buffer
953 as well as returning it.
955 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure
958 1999-07-13 Gary Houston <ghouston@easynet.co.uk>
960 * strports.c (scm_strprint_obj): simplify. start with initial
962 (st_seek): don't allow string to be extended if seeking past
963 the end of a read-only port.
965 1999-07-12 Gary Houston <ghouston@easynet.co.uk>
967 * strports.c (st_seek): change the resize checks.
969 * ports.c (scm_ftruncate): throw error if offset works out negative.
971 * strports.c (st_flush): increase string size in blocks of
972 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
973 it's greater and reset read_buf_size.
974 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
975 to be maintained for output ports too (it holds the written
976 part of the string, while write_buf may have unwritten buffer
978 (st_truncate): rewritten.
979 (top of file): added a few notes.
981 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
983 Patch from Greg Badros:
984 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
985 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
986 (function pointer) argument to scm_make_gsubr and scm_make_subr
987 calls. This avoids warnings in C++ programs using guile-snarf.
989 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
991 * strports.c (st_grow_port): set pt->read_pos. set
992 pt->read_buf_size one less than pt->write_buf_size if there's
993 an unwritten char at the end of the string. similarly for
995 (st_resize_port): renamed from st_grow_port.
996 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
997 seek from read_end instead of write_end for SEEK_END.
998 (st_ftruncate): calculate current length using readbuf, not write
1000 (scm_strport_to_string): use read_buf_size for length.
1001 (stfill_buffer): don't re-initialise the readbuf.
1003 1999-07-05 Gary Houston <ghouston@easynet.co.uk>
1005 * strports.c (scm_strport_to_string): new procedure.
1006 (scm_call_with_output_string, scm_strprint_obj): use
1007 scm_strport_to_string.
1008 used SCM_INUM0 instead of SCM_MAKINUM (0) in a few places.
1010 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1012 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)
1014 Fri Jun 25 22:14:32 1999 Greg Badros <gjb@cs.washington.edu>
1016 * smob.c: added scm_make_smob_type_mfpe (), scm_set_smob_mfpe ();
1017 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
1018 and "bigneg" smob types.
1020 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
1021 SCM_RETURN_NEWSMOB macro. Added protos for new functions in
1024 * *.c: Use scm_make_smob_type_mfpe, instead of scm_newsmob, and
1025 use SCM_NEWSMOB or SCM_RETURN_NEWSMOB in constructors instead of
1026 SCM_NEWCELL and setting the CAR/CDR by hand.
1028 1999-07-04 Gary Houston <ghouston@easynet.co.uk>
1030 * ports.c (scm_putc): call scm_read_flush.
1031 (scm_puts): likewise.
1032 (scm_lfwrite): likewise.
1033 (scm_lseek): likewise.
1034 (scm_ftruncate): likewise.
1035 * unif.c (scm_uniform_array_write): likewise.
1036 * ioext.c (scm_redirect_port): likewise.
1038 * ports.c (scm_fill_buffer): don't take pt argument. change callers.
1039 (read_flush_void_port): new proc, for void port ptob.
1041 * vports.c (sf_read_flush): likewise.
1042 * strports.c (st_read_flush): take offset arg.
1043 * fports.c (local_read_flush): use offset, don't reset putback
1046 * ports.h (scm_ptobfuns): let read_flush take an offset argument,
1047 which is the number of chars from the putback buffer.
1049 * ports.c (scm_read_flush): new procedure, resets the putback
1050 buffer before calling the ptob routine.
1052 * strports.c (scm_strprint_obj): bug fix: get pt from the port,
1053 not from the parameter obj. (Thanks to Eric Moore.)
1055 * ports.h: SCM_CRDY, SCM_CUC, SCM_CRDYP, SCM_SETRDY, SCM_CUNGET,
1056 SCM_CGETUN, SCM_CLRDY, SCM_TRY_CLRDY, SCM_N_READY_CHARS: deleted.
1058 * strings.c (scm_make_string): throw error if 2nd arg isn't
1061 * unif.c (scm_uniform_array_read_x): fix reading from a port.
1063 (scm_uniform_array_write): likewise.
1065 1999-06-29 Gary Houston <ghouston@easynet.co.uk>
1067 * ports.c (scm_drain_input): rewritten.
1069 * fports.c (local_fclose): check putback_buf.

1110 trinary conditional in order for the flag computation to be
1113 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1115 * struct.c, struct.h:
1117 In order to support different kinds of deallocation, a destructor
1118 slot has been added to struct vtables. This allows for structs
1119 containing pointers to other memory blocks.
1121 (scm_struct_i_free): New hidden struct slot. Holds destructor for
1122 instances to this vtable.
1123 (scm_struct_free_0): New destructor: Doesn't deallocate data.

1135 scm_struct_i_size which holds the size of light structs.
1136 (scm_struct_i_n_words): This slot has changed meaning. Previously
1137 it included hidden slots. Now it indicates visible slots.
1138 (scm_alloc_struct): Clear flags.
1139 (SCM_STRUCTF_MASK): 4 new flag positions added => 12 bits.
1141 (struct_num, scm_struct_i_tag): Removed.

1188 pointers. (Thanks to Mark Elbrecht.)
1190 1999-06-19 Jim Blandy <jimb@savonarola.red-bean.com>
1192 Patch from Greg Harvey:
1193 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1194 around the condition of an `if', `while', etc., even if the
1195 condition is a macro invocation that expands to something
1196 surrounded by parens. It's more readable.
1198 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1199 proper lists, and of the appropriate lengths.
1200 (check_map_args): New function. (Thanks to Greg Harvey for the
1203 1999-06-19 Michael Livshin <mike@olan.com>

1222 (scm_igc): Check for underflow by seeing if this is negative.
1224 * gc.h (scm_mallocated): Fix declaration.
1225 (Thanks to Greg Harvey.)
1227 * ports.h: #include <sys/types.h>, to get a definition for `off_t'.

1236 vector contents, to be used only during garbage collection.
1237 * weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
1238 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
1240 (scm_weak_size, scm_n_weak): Deleted.
1241 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
1242 vectors without allocating new storage during GC, using
1243 scm_weak_vectors as the head of the chain.
1244 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1245 instead of stepping through an array.
1246 (scm_gc_sweep): Update offset used to find start of weak vector to
1248 (scm_init_storage): Set scm_weak_vectors to EOL.
1250 Fix from Ken Raeburn <raeburn@raeburn.org>:
1251 * gc.c (already_in_gc): New variable.
1252 (scm_igc): Set and clear already_in_gc; abort if it's set at
1255 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
1257 Fix from Gary Houston:
1258 * fports.c (local_seek): Signal an error if the seek fails.
1259 * ports.c (scm_lseek): Don't check return value of port's seek
1260 function; it's its job to signal an error if there's a problem.
1262 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
1264 * strports.c (scm_call_with_output_string): Don't include the

1270 scmsigs.c, strports.c, vports.c: Install the sources which
1271 actually correspond to the changes described below. I got the
1272 ChangeLog entries and the patch from two different places...
1274 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1276 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1277 it shows up as terrible performance, as we GC constantly.
1279 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1280 newline. A bit faster, and definitely hairier.
1281 (scm_read_line): Count newlines here instead.
1283 * strings.c (scm_take_str): New function.
1284 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1285 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
1286 scm_take_str, to avoid copying the string.
1288 Add some simple-minded support for line buffered ports.
1289 * ports.h (SCM_BUFLINE): New flag for ports.
1290 * init.c (scm_init_standard_ports): Request line-buffering on
1291 the standard output port.
1292 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1294 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1295 and there's a newline to be written, flush the port.
1297 Gary Houston's open-buffer port patches:
1299 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1301 * ports.c: (scm_lseek): clear buffers even if just reading current
1304 * fports.c (local_fclose): call local_fflush unconditionally.

1310 strports.c: take care of rw_active and rw_randow.
1311 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
1312 strports.c (scm_mkstrport): check that pos is reasonable.
1313 ioext.c (scm_ftell, scm_fseek): use lseek.
1314 (SCM_CLEAR_BUFFERS): macro deleted.

1317 ports.c (scm_newptob): set ftruncate.
1319 ports.c (scm_ftruncate): new procedure.
1320 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
1321 strports.c (st_seek, st_grow_port): new procs.
1322 fports.h (scm_port): change size types from int to off_t.
1323 ports.c (scm_init_ports): initialise the seek symbols here
1324 instead of in ioext.c.
1325 strports.c (scm_call_with_output_string): start with an empty
1326 string, so seek and ftruncate can be used.
1328 gdbint.c: adjust string port usage.
1330 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1332 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1333 equivalent to fflush for the read buffer.
1334 * ports.c (scm_newptob): set read_flush.
1335 ports.c (void_port_ptob): set read_flush.
1336 fports.c (local_read_flush): new proc. add to ptob.
1337 strport.c (st_read_flush): likewise.
1338 vport.c (sf_read_flush): likewise.
1339 fports.h (struct scm_fport): remove random member. there's nothing
1340 left but fdes. leaving it as a struct to allow for future changes.
1341 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1342 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1343 ptob proc if the read buffer is filled.
1345 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1347 * ports.h (scm_port): add a rw_random member and replace
1348 reading and writing members with rw_active member.
1349 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1351 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1353 * ports.h (struct scm_port_table): add writing and reading members
1354 to replace write_needs_seek: it isn't good enough for non-fports.
1355 ports.c, ioext.c, fports.c: corresponding changes.
1356 (struct scm_port_table): give it a typedef and rename to scm_port.
1357 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1358 corresponding changes.
1360 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
1362 * ports.c (scm_newptob): bugfix: set seek member.
1363 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
1364 and generalised to all port types.
1366 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
1368 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1369 signals (it was only being done for handlers installed from Scheme).
1370 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1371 waiting for input caused an EINTR error from read.
1373 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1375 * ports.h (struct scm_port_table): make all the char members
1376 unsigned, so they convert to int without becoming negative if large.
1378 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1380 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1381 with threads enabled. rename this procedure to
1382 fport_wait_for_input and take a port instead of a fdes.
1383 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1385 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1386 get readline support working again: use fdopen to get FILE objects.
1388 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1390 * gc.c (scm_init_storage): install an atexit proc to flush the
1392 (cleanup): the new proc. it sets a global variable which can be
1393 checked by the ptob flush procs to avoid trying to throw
1394 exceptions during exit. not very pleasant but it seems more reliable.
1395 * fports.c (local_fflush): check terminating variable and if set
1396 don't throw exception.
1397 * CHECKME: that the atexit proc is installed if unexec used.
1399 * throw.c (scm_handle_by_message): don't flush all ports here.
1400 it still causes bus errors.
1402 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1403 and move to ioext.c.
1405 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1407 * ports.c (scm_char_ready_p): check the port buffer and call the
1408 ptob entry if needed.
1410 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1411 ptob initialisers. use it in char-ready
1413 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1415 * vports.c (sfflush): modified to write a char (since softports
1416 currently use shortbuf.)
1418 * fports.c (scm_standard_stream_to_port): moved to init.c and
1421 * init.c (scm_init_standard_ports): make stdout and stderr
1422 unbuffered if connected to a terminal. with stdio they
1423 were line-buffered by default.
1425 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1428 * ports.h (scm_ptobfuns): change fflush return to void.
1429 change flush proc definitions.
1431 * strports.c (scm_call_with_output_string): get size from
1432 buffer instead of port stream.
1433 (st_flush): new proc.
1435 * ports.h (struct scm_port_table): added write_end member,
1436 as an optimisation. set it where write_buf_size is set.
1438 * ports.h (struct scm_port_table): change stream from void *
1439 back to SCM. SCM presumably must be large enough to hold a
1440 pointer (and probably vice versa but who knows.)
1441 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1443 (scm_puts): rewritten
1444 * fports.c (local_ffwrite, local_fputs): removed.
1445 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)
1446 * vports.c (sfputc, sfputs, sfwrite) likewise.

1450 * ports.c (scm_lfwrite): rewritten using fport.c version.
1452 * fports.c (local_fputc): deleted.
1454 * ports.c (scm_add_to_port_table): initialise write_needs_seek.
1456 * ports.h (scm_ptobfuns): add seek function pointer.
1457 * fports.c: set it to local_seek, new procedure.
1460 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1461 use ptob for seek. take ptob instead of fport arg.
1463 * ports.h (struct scm_port_table): new member write_needs_seek,
1464 replaces reading member in fport struct.
1466 * vports.c (sfgetc): store the getted char into the buffer.
1467 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1468 the Scheme interface is still a procedure that gets a char.
1469 (scm_make_soft_port): set up the port buffer (shortbuf).
1471 * fports.c (local_fgetc, local_fgets): deleted.
1472 * strports.c (stgetc): likewise.
1473 * ports.c: scm_generic_fgets: likewise.
1475 * ports.h (scm_ptobfuns): add fill_buffer.
1476 * ports.c (scm_newptob): assign it.
1477 * strports.c (scm_mkstrport): set up the buffer.
1478 put just the string into the stream, not cons (pos stream).
1479 (stfill_buffer): new proc.
1481 * ports.h: fport buffer moved into port table: to be
1482 used for all port types.

1491 scm_getpeername, scm_recv, scm_send, scm_recvfrom,
1493 use SCM_FPORT_FDES. use SCM_OPFPORTP not SCM_FPORTP.
1495 * posix.c (scm_getgroups): use SCM_ALLOW/DEFER_INTS.
1496 (scm_ttyname): use SCM_FPORT_FDES.
1497 (scm_tcgetpgrp, scm_tcsetpgrp): likewise.

1503 (scm_fdes_to_ports): modified.
1504 (scm_fdopen): use scm_fdes_to_port.
1506 * ports.c (scm_init_ports): don't try to flush ports using
1507 atexit(). it's too late, errors will cause SEGV.
1509 * fports.c (scm_fport_buffer_add): new procedure.
1511 * fports.h (SCM_FDES_RANDOM_P): new macro. use it in
1512 scm_fdes_to_port and scm_redirect_port.
1514 * ioext.c (scm_redirect_port): use setvbuf to set buffers in the
1515 new port. reset fp->random.
1517 * fports.c (scm_fdes_to_port), ports.c (scm_void_port),
1518 filesys.c (scm_opendir):
1519 restore defer interrupts while the port is constructed.
1520 (scm_setvbuf): if mode is _IOFBF and size is not supplied,
1521 derive buffer size from fdes or use a default.
1522 (scm_fdes_to_port): use setvbuf instead of creating the buffers
1525 vports.c (various places): use SCM_SSTREAM.
1526 strports.c: likewise.
1527 * gdbint.c: likewise.
1528 * ports.h (SCM_SSTREAM): new macro.
1530 * fports.c (scm_input_waiting_p): use scm_return_first, since port
1531 may be removed from the stack by the tail call to scm_fdes_waiting_p.
1533 * fports.h (SCM_CLEAR_BUFFERS): new macro.
1535 * filesys.c (scm_fsync): use SCM_FDES.
1537 * ports.c (scm_force_output): call scm_fflush.

1553 ports.c fports.c ioext.c posix.c socket.c net_db.c filesys.c:
1554 removed all uses of SCM_DEFER/ALLOW ints for now. they were mainly
1555 just protecting errno. some may need to be put back.
1557 * scmsigs.c (take_signal): save and restore errno while this
1560 *fports.c (print_pipe_port, local_pclose, scm_pipob): deleted.
1561 open-pipe, close-pipe are emulated in (ice-9 popen)

1675 1999-05-09 Jim Blandy <jimb@savonarola.red-bean.com>
1677 * strop.c (scm_string_capitalize_x): Use the SCM object `s' in
1678 error messages, not the uninitialized string `str'. Love that
1681 * strop.c (scm_substring_move_x): New function, which can handle
1682 arbitrary overlapping substrings.
1683 (substring-move-left!, substring-move-right!): These are
1684 now just synonyms for substring-move!.

1757 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1759 * numbers.c (isfinite): Define this macro if not defined: Return a
1760 non-zero value if X is finite. (From ISO C 9x standard.)
1761 (scm_inexact_to_exact): Bugfix: Don't pass NaNs to scm_dbl2big.
1762 (Thanks to Jon Trowbridge and Greg Harvey.)
1764 1999-03-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1789 (scm_system_module_env_p): Assume root environment is no lookup
1792 * debug.c, eval.c, evalext.c, gdbint.c stacks.c:

1802 * error.c (scm_wta): Pass SCM_LIST1 (arg) instead of SCM_EOL to
1803 scm_misc_error when pos is a string. This allows for dispatching
1804 arbitrary error messages with one argument via SCM_ASSERT:

1807 1999-03-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1813 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1815 Most of this batch of changes is about how to deal with extended
1816 types when an object system is loaded into Guile. A nice object
1817 system is capable of representing Guile's types as class objects.
1819 For example, we want a regular expression to be of class <regex>.
1820 But regular expressions are smobs which aren't under direct
1821 control of the object system, so there has to be some mechanism
1822 which informs the object system that a new class should be created
1823 which can represent the smob type. I call this a "wrapper class".
1825 * objects.c: #include "smob.h";
1826 (scm_class_keyword): Removed. (Class is automatically created by
1828 (scm_smob_class): Array of smob classes indexed by smobnum.
1829 (scm_make_extended_class): "Plugin" function pointer for creation
1830 of wrapper classes for smob and struct types.
1831 (scm_class_of): Handle compiled closures. (Currently regarded as
1833 Use scm_smob_class to handle smob types;
1834 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1835 through scm_smob_class;
1838 * smob.c (scm_newsmob): Also create a wrapper class if
1839 scm_smob_class has been initialized.
1841 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1842 type code and smobnum.
1844 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1845 (scm_struct_table): Weak key table with auxilliary information for
1846 struct types. Currently used for names and wrapper classes.
1847 (scm_struct_ihashq): Hash function for structs.
1848 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1849 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1850 for accessing names of vtables. The record implementation in
1851 boot-9.scm currently uses the setter to record the name of record
1852 types. When the object system is initialized, it can use this
1853 information to create wrapper classes with suitable names.
1854 (scm_init_struct): Allocate scm_struct_table.
1855 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1856 (struct tags are a finite resource and we might want to restrict
1857 the use of tags to vtables only. E.g., Goops only uses tags for
1859 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1861 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1864 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1865 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1866 Used for access of struct table entries.
1868 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1869 (scm_hash_fold): New procedure. Used to process all entries in a
1870 hash table (in no particular order).
1872 Argh! For the umpteenth time I got compilation errors because of
1873 the "intuitive" name `kw'. This has to have an end:
1875 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1876 "kw" --> "keywords" everywhere.
1877 (I doubt that this will cause big compatibility problems since the
1878 application interface is unaffected.)
1880 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1882 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1884 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1885 column inums to native form.
1887 Improvement of backtraces: Introduces a new stack narrowing
1888 specifier, #t, for the inner cut. (See further in the comments in
1889 stacks.c:narrow_stack ().)

1892 (Used to flag certain system procedures which shouldn't turn up in
1895 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1896 modules which aren't "user" modules and the code of which
1897 shouldn't turn up in backtraces.)

1900 Extract the lookup closure from an environment.
1901 (scm_system_module_env_p): New function: Return non-#f if MODULE

1907 * debug.c (scm_procedure_name): Use name property in the default
1910 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1912 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1914 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1915 procedure throughout.
1917 * print.c (scm_iprin1): Removed extraneous space when printing
1918 procedure-with-setters.
1920 Entity and operator setter slots were introduced as a complement
1921 to the <procedure-with-setter> type in order to support entities
1922 and operators with setters in a reasonable and efficient way.
1923 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1926 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1936 1999-03-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1938 * objects.h (SCM_OBJ_CLASS_REDEF): New macro: Find class slots
1939 directly through the instance.
1941 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1943 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1944 scm_struct_i_flags instead of scm_vtable_index_layout!
1946 * list.c (scm_list_star): New procedure.
1948 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1950 * debug.c (scm_init_debug): Added scheme level constant

2029 SYMB now point to const.
2031 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2033 * print.c (scm_iprin1): Use scm_procedure_name instead of
2034 scm_procedure_property for compiled closures.
2036 * tags.h (scm_tc7_pws): New procedure type. Four representations
2037 for procedure-with-setters were considered before selecting this
2040 1. A closure where the CODE and ENV slots are used to represent
2041 the getter and a new SETTER slot is used for the setter. The
2042 original getter is stored as a `getter' procedure property. For
2043 closure getters, the CODE and ENV slots contains a copy of the
2044 getter's CODE and ENV slots. For subr getters, the CODE contains
2047 2. A compiled closure with a call to the getter in the cclo
2048 procedure. The getter and setter are stored in slots 1 and 2.
2050 3. An entity (i.e. a struct with an associated procedure) with a
2051 call to the getter in the entity procedure and the setter stored
2052 in slot 0. The original getter is stored in slot 1.
2054 4. A new primitive procedure type supported in the evaluator. The
2055 getter and setter are stored in a GETTER and SETTER slot. A call
2056 to this procedure type results in a retrieval of the getter and a
2057 jump back to the correct eval dispatcher.
2059 Representation 4 was selected because of efficiency and
2062 Rep 1 has the advantage that there is zero penalty for closure
2063 getters, but primitive getters will get considerable overhead
2064 because the procedure-with-getter will be a closure which calls
2067 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
2068 <procedure-with-setter>, but together with rep 2 it suffers from a
2069 three level dispatch for non-GOOPS getters:
2071 cclo/struct --> dispatch proc --> getter
2073 This is because the dispatch procedure must take an extra initial
2074 argument (cclo for rep 2, struct for rep 3).
2076 Rep 4 has the single disadvantage that it uses up one tc7 type
2077 code, but the plan for uniform vectors will very likely free tc7
2078 codes, so this is probably no big problem. Also note that the
2079 GETTER and SETTER slots can live directly on the heap, using the
2080 new four-word cells.
2082 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,
2083 SCM_SETTER): New macros.

2109 * eval.h: Declare scm_s_set_x, scm_sym_set_x;
2111 * eval.c: Renamed "set" --> "set_x" in various names for
2112 consistency of name correspondence between Scheme and C;
2113 Renamed scm_i_set_x --> scm_sym_set_x and made global.
2114 Renamed s_set_x --> scm_s_set_x and made global.
2116 1999-01-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2118 * random.c (scm_i_random_bignum): Made independent of endianness.

2136 scm_rstate from seed.
2137 (scm_copy_random_state, scm_seed_to_random_state): New functions.
2138 (scm_make_random_state): Removed.
2140 * random.c (scm_make_random_state): Use scm_i_make_rstate().

2150 * sort.c (scm_merge, scm_merge_list_x): Bugfix: Place elements
2151 from first arg before equal elements in second arg in result.
2152 (scm_merge_list_step): Bugfix: Don't presume that arguments in a C
2153 function call are executed in a well defined order.
2155 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2157 * alloca.c (alloca): Cast value returned by malloc. (Thanks to
2160 1999-01-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2162 * random.c: Removed alloca includes.
2164 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2166 * Makefile.in: This changed, for some reason I don't really
2167 understand, when I ran automake in the top level directory. This
2168 may be contamination by Cygnus internal releases. If you re-run
2169 automake and this change gets reverted, don't worry about it.
2171 1999-01-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2173 * sort.c, sort.h: New files: Implement slib's and scsh's sort

2186 * random.c, random.h: New files: Random number support.
2187 Interface same as slib's.
2189 * Makefile.am: Added random.c, random.h, random.x.
2191 * init.c: #include "random.h";

2198 * guardians.c, guardians.h (scm_make_guardian,
2199 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
2200 scm_get_one_zombie, scm_init_guardian): This is an implementation
2201 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
2202 David Eby (1993) "Guardians in a Generation-Based Garbage
2203 Collector" ACM SIGPLAN Conference on Programming Language Design
2204 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
2205 /pub/scheme-repository/doc/pubs/guardians.ps.gz
2206 Author: Michael N. Livshin.
2208 * gc.h (SCM_MARKEDP, SCM_NMARKEDP): New macros.
2210 * gc.c (scm_igc): Call scm_guardian_gc_init and
2211 scm_guardian_zombify.

2215 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2217 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
2220 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2222 Move the procedure slots of entities to invisible slots (so that
2223 we can have operator class objects which themselves are entities).
2224 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
2225 SCM_STRUCTF_ENTITY): New constants.
2227 * struct.c (scm_make_struct): Allocate "invisible" room for
2228 procedures if SCM_STRUCTF_ENTITY is set in vtable.
2230 * gc.c (scm_gc_mark): Mark entity procedures.
2232 * struct.c, struct.h (scm_alloc_struct): Renamed from alloc_struct

2237 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
2238 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
2240 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
2242 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
2243 of syntactic forms, similar to SCM_PROC.
2244 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
2245 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
2246 for the name symbols when needed.
2248 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
2250 * Makefile.in: Regenerated.
2252 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
2254 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
2255 take the address of _into; it might be a register. Just have
2256 scm_debug_newcell return the new cell.
2257 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2258 taking the address of a place to store it as an argument.
2259 * gc.h (scm_debug_newcell): Change declaration.
2260 (Thanks to Greg Harvey.)
2262 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2264 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
2265 Replaces old names serial-array-copy! and serial-array-map!.
2267 * evalext.c (map-in-order): New name. Replaces serial-map.

2271 * smob.c (freeprint): New function.
2272 (freecell): Use it to print freed objects, for slightly easier
2275 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2277 * backtrace.c (display_frame): Made more robust. Doesn't throw an
2278 error if no source properties can be found for a frame. (Thanks
2279 to Christian Lynbech.)
2281 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2283 * objects.h: Removed slots direct_supers and direct_slots from the
2284 definitions of the rudimentary classes described by objects.h.
2286 * objects.c, objects.h (scm_entity_p): New procedure. Together
2287 with the predicates scm_procedure_p and scm_struct_p, this
2288 predicate makes it possible to differ between structs, entities
2291 * modules.c, modules.h (scm_resolve_module): New function.
2293 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2295 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2296 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2299 * objects.c (scm_entity_p): New procedure.
2301 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
2302 for asubrs, rpsubrs, lsubrs and lsubr_2s.
2304 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2306 * procprop.h (scm_i_procedure_arity): Added declaration.
2308 * procprop.c (scm_i_procedure_arity): Made global; New code to
2309 handle operators and entities.
2310 (scm_procedure_property): No need to call scm_procedure_p since
2311 scm_i_procedure_arity now does all necessary type checking.
2312 Added #include "objects.h".
2314 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2315 s_add_hook_x --> s_remove_hook_x.
2316 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
2317 Added #include "procprop.h"
2319 * feature.c, feature.h (scm_reset_hook_x): New procedure.
2320 (scm_make_hook): Optional argument defines number of arguments to
2322 (scm_make_named_hook): Take number of args as second arg.
2323 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2324 boot-9.scm for a while); First arg is the hook. The rest are
2325 arguments passed on to the hook procedures.
2327 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2329 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2330 scm_logbit_p): Do the computation in ulongs. This is not as nice
2331 as doing it in bignums, but at least it's good enough for
2332 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2334 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2335 subexpressions. (Thanks to Charbel Jacquin.)
2337 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2339 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2340 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2341 (scm_make_named_hook): New function.
2343 * feature.c: Added #include "eval.h".
2345 * modules.c (scm_make_module): Beautify the module.
2347 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2349 * modules.c, modules.h: New files: C interface to modules. (This
2350 is necessary in order to interface the object system to Guile
2351 properly. The guts of these modules will be replaced by the new
2352 module system in the future.)
2354 * init.c: Added #include "modules.h"
2355 (scm_boot_guile_1): Call scm_init_modules.
2356 (invoke_main_func): Call scm_post_boot_init_modules.
2358 * Makefile.am: Added modules.c, modules.x, modules.h.
2360 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2362 * procs.c: #include "objects.h"
2363 (scm_procedure_p): Return #t also on structs which are operators.
2365 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2366 <operator-metaclass> and <entity-class> to <standard-class>,
2367 <operator-class> and <entity> in order to conform with STKlos
2370 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2371 which isn't an operator.
2372 (SCM_APPLY): Ditto, but jump to badproc.
2374 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2376 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2377 Previously, structs implanted in code were interpreted as forms
2378 the operator of which was a gloc. We solve this by checking for
2379 the zero in the emulated vcell in the struct vtable. Since
2380 implanted structs always will look like forms with a gloc
2381 operator, execution will only be slowed down by maximally one
2382 extra test-and-branch per application.
2384 * evalext.c (scm_definedp): Removed check for isyms; Added a
2385 second optional argument: It is now possible to supply an
2386 evaluation environment in which to look for the symbol.
2388 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2390 * readline.c (scm_init_readline): Set
2391 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2393 * coop.c (coop_condition_variable_wait): Removed
2394 (coop_condition_variable_wait_mutex): Folded logic of
2395 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2396 prevent condvar signal lossage. Previously, another thread could
2397 start to run after unlocking the mutex but before putting the
2398 current thread on the wait queue. If that thread then would
2399 signal the first, the signal would be lost. (Thanks to Christian
2402 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2404 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2407 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2409 * objects.c (scm_i_make_class_object): Renamed from
2410 make_class_object; exported; error checking moved to
2411 scm_make_class_object and scm_make_subclass_object.
2412 (scm_make_class_object, scm_make_subclass_object): Use
2413 scm_i_make_class_object.
2414 (scm_make_subclass_object): Let the subclass have same metaclass
2417 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2419 * debug.c (scm_debug_options): Bugfix: Set the value of
2420 scm_stack_checking_enabled_p after setting debug options;
2421 #include "stackchk.h". (Thanks to Richard Polton.)
2423 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2425 * unif.c (scm_array_contents): removed unnecessary test for 0
2428 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2430 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2431 Replaced by macro `collect' in boot-9.scm.
2433 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2435 * eval.c (scm_copy_tree): Copy source properties if existent.
2437 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2438 don't, we may end up passing memoized source to a transformer.)
2440 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2442 * stack.c (get_applybody): Help function which lookups the first
2443 body form of the apply closure.
2444 (read_frames): Prevent the source of the first form of the apply
2445 closure from being recorded. This would only be confusing.
2447 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2448 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2450 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2452 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2454 (read_frames): Use SCM_MACROEXPP.
2456 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2458 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2459 don't contain interesting information since all arguments are
2460 present in the frame which applies the compiled closure anyway.);
2461 Skip the transformer application frames.
2463 * print.c (scm_iprin1): Print gsubrs as primitives.
2465 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2467 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2469 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2470 that we can identify these in a backtrace. (This change doesn't
2471 introduce any significant speed penalty.)
2473 * eval.c: Added note about `serial-map' using scm_map.
2475 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2476 readline options. They should reside in their own options array.
2478 * readline.c, readline.h (scm_readline_options,
2479 scm_readline_opts): Moved readline options here.
2481 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2483 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2484 SCM_ROCHARS instead of SCM_CHARS.
2486 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2487 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2489 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2491 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2492 This is quite important since the latter clears the
2493 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2494 every single character read...
2496 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2498 * print.c (scm_iprin1): Removed suspect looking (and indeed
2499 malevolent) semicolon after test for user supplied closure print
2500 procedure. (Thanks to Telford Tendys.)
2502 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2503 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2504 starting to search the list. Removed call to sloppy_mem_check.
2506 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2507 procedures: Same as scm_delq_x et al, but delete maximally one
2510 * options.c (scm_options, scm_init_options): GC-protect option
2511 values of type SCM. (Thanks to Telford Tendys.)
2513 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2515 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2516 make sure that there always is a "real" scm_lookupcar.
2518 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2520 * read.c, read.h (scm_read_opts): New read options
2521 "history-length" and "history-file".
2522 (scm_read_options): Stifle history to history length.
2524 * readline.c (scm_read_history, scm_write_history): New procedures.
2526 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2528 * eval.h (scm_macro_eval_x): Removed declaration.
2530 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2531 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2532 Renamed and made global.
2534 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2535 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2537 * evalext.c, evalext.h: New files. Contain non-R5RS things
2538 having to do with evaluation.
2540 * evalext.c (scm_serial_map): New procedure: Version of `map'
2541 which guarantees that the procedure is applied to the lists in
2543 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2544 returns a list of the results of the body forms instead of the
2545 result of the last body form.
2546 (scm_definedp, scm_m_undefine): Moved from eval.c
2548 * evalext.h (scm_m_sequence_to_list): Added declaration.
2550 * macros.c, macros.h: New files.
2551 (scm_procedure_to_syntax, scm_procedure_to_macro,
2552 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2553 scm_macro_name, scm_macro_transformer): Moved from eval.c
2554 (scm_make_synt): Moved from eval.c
2556 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2558 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2561 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2563 * debug.c, print.c: Added #include "macros.h".
2565 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2567 This change adds the ability to use `unread-char' multiple times
2568 without interspersed reads and adds the new procedure
2569 `unread-string'. The change is optimized for the common case of
2570 unreading a single character. This is also the reason behind the
2571 choice to store characters in the port itself: in most cases no
2572 extra malloc is required.
2574 The amount of code in some macros in ports.h has been increased to
2575 the extent that they would fit better as C functions, but, since
2576 this code belongs to the port representation, such functions
2577 should be placed in ports.c which would cause calls back and forth
2578 between ports.c and genio.c. That is not good for performance.
2579 Also, keeping them as macros allows the compiler to do some
2580 optimizations which are needed to make the current interface
2581 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2583 One benchmark (Guile startup time) indicates an increase of
2584 loading speed of 1%. Another (reading (using `read') boot-9.scm
2585 10 times) shows no change in performance.
2587 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2588 made to find a beautiful solution.)
2590 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2591 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2592 character. (SCM_CLRDY clears all.)
2593 (SCM_N_READY_CHARS): New macro: Returns number of unread
2594 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2595 (struct scm_port_table): New fields: `entry' contains port table
2596 index, `cp' points to last unread char, `cbuf' is the buffer for
2597 unread chars, `cbufend' points after end of the character buffer.
2599 * ports.h, ports.c (scm_unread_string): New procedure.
2600 (scm_grow_port_cbuf): New function.
2602 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2604 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2605 to read unread characters. Use SCM_TRY_CLRDY instead of
2608 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2610 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2612 * genio.c, genio.h (scm_ungets): New function.
2614 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2617 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2619 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2620 declarations. (Thanks to Russ McManus.)
2622 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2624 * numbers.c (num2long): As a software archeologist, I'm proud of
2625 this finding! :) Preliminary dating suggests an almost 4 year old
2626 remnant from the SCM ancestor. The sample has been removed from
2627 the finding site and is now safely stored in the repository.
2629 * numbers.h: Removed prototype for num2long.
2631 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2633 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2634 array as second arg.
2635 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2636 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2637 * gh.h: Updated and added prototypes.
2639 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2641 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2643 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2645 * guile-snarf.in: Never generate an empty file. (Thanks to
2648 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2649 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2650 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2651 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2652 gh_new_procedure5_0): Specify argument types, to appease C++
2653 compilers. (Thanks to Brad Bowman.)
2655 Bug reports from Russ McManus:
2656 * guile-snarf.in: If the CPP environment variable is set, use that
2657 as the C preprocessor, instead of the preprocessor autoconf
2659 * snarf.h (SCM_PROC): Cast the function pointer passed to
2660 scm_make_gsubr, to satisfy C++.
2662 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2663 Use the handler passed, instead of ignoring it and using
2664 gh_standard_handler. (Thanks to Etienne Bernard.)
2666 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2668 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2671 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>
2673 * __scm.h, alist.c, async.c, async.h, backtrace.h, chars.c,

2688 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2691 * script.c (scm_compile_shell_switches): Define
2692 use-emacs-interface in the root module, so the repl code can see
2693 it. See today's change to top-repl in ice-9/boot-9.scm.
2695 * filesys.c (set_element, get_element): Make sure that `element'
2696 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2697 Boekemeier and Jorgen "forcer" Schaefer.)
2699 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2701 * chars.c (scm_charnames): In ASCII character name table, make
2702 newlines print as #\newline by default, not #\nl.
2704 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2705 alphabetical order. Oh thrills. But it helps me know how far
2706 along in the compilation I am.
2707 * Makefile.in: Regenerated.
2709 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2711 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2712 #bytes(...) to #y(...), and syntax for short vectors from
2713 #short(...) to #h(...). This may seem nutty, but, like the other
2714 uniform vectors, byte vectors and short vectors want to have the
2715 same print and read syntax (and, more basic, want to have read
2716 syntax!). Changing the read syntax to use multiple characters
2717 after the hash sign breaks with the conventions used in R5RS and
2718 the conventions used for the other uniform vectors. It also
2719 introduces complexity in the current reader, both on the C and
2720 Scheme levels. (The Right solution is probably to change the
2721 syntax and prototypes for uniform vectors entirely.)
2723 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2725 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2726 (Thanks to Jorgen "forcer" Schaefer.)
2727 * ports.h (SCM_NOFTELL): New flag.
2728 * fports.c (local_fgets): If it's set, use the generic fgets.
2729 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2731 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2733 * script.c (scm_compile_shell_switches): Add handling of -q switch
2734 (inhibit loading of user init file).
2735 (scm_shell_usage): Add usage text for -q switch.
2736 (scm_compile_shell_switches): Always load user init file first if
2737 it is loaded at all.
2739 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2741 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2742 and is now broken under NetBSD. I can't fathom what it's trying
2743 to do, so I've replaced it with something that I do understand,
2744 which seems to work, and which isn't broken on NetBSD. "Progress?
2745 You Decide." (Thanks to Perry Metzger.)
2747 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2748 signed/unsigned comparison.
2750 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2752 Warning fixes from Greg Harvey:
2753 * unif.c (scm_array_set_x): initializer for pos
2754 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2755 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2756 initializers for field_type, since EGCS so desparately wants to
2758 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2759 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2760 when GUILE_DEBUG is defined.
2761 * dynwind.h (scm_wind_chain): Same.
2762 * ports.h (scm_pt_size, scm_pt_member): Same.
2763 * print.h (scm_current_pstate): Same.
2764 * procs.h (scm_make_cclo): Same.
2766 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2768 Handle short and long long uniform arrays properly. (Thanks to
2770 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2771 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2772 scm_tc7_llvect (long long vectors).
2774 Change the way libguile and boot-9.scm are timestamped, to try to
2775 get rid of these spurious mismatch warnings. Now both
2776 libguile/versiondat.h and ice-9/version.scm are generated directly
2777 by the configuration process, rather than having version.scm
2778 generated directly, and libguile/versiondat.h generated by the
2779 Makefile, which is generated by configure. It seems that
2780 sometimes the Makefile would change, but versiondat.h depends on
2781 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2782 * Makefile.am (versiondat.h): Target removed; this is generated
2783 directly by the configure script now.
2784 (BUILT_SOURCES): Remove versiondat.h.
2785 * versiondat.h.in: New file, transformed by the configure script
2787 * Makefile.in: Regenerated.
2789 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2790 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2791 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2792 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2793 if we want to use them in a header file some day, we can. (Thanks
2794 to Michael Livshin.)
2796 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2797 SCM numbers, so we won't have rollover problems; the range of a
2798 signed long in milliseconds is about 25 days. (Thanks to Karl
2801 Don't redefine sleep and usleep; fix this problem now.
2802 * coop.c (sleep, usleep): Remove declarations; we don't use or
2803 redefine these any more.
2804 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2805 job of usleep and sleep in a thread-friendly way. We can use
2806 these in the rest of Guile. Define versions for systems both with
2807 and without iselect.
2808 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2809 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2810 we're just using it, not redefining it, we can use a K&R style
2812 (sleep): Declare this, too, if the system hasn't.
2813 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2814 scm_uthread_sleep if they're available; otherwise, just call the
2816 * scmconfig.h.in: Regenerated.
2818 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2820 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2822 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2824 * threads.c: Doc fix.
2826 The argument type of usleep varies from system to system,
2827 as does the return type. We really shouldn't be redefining usleep
2828 at all, but I don't have time to clean that up before the 1.3.
2829 release. It's on the schedule for afterwards. (Thanks to Julian
2831 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2833 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2834 * scmconfig.h: Regenerated.
2836 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2837 right way to handle system variation. Autoconf's approach is the
2839 * simpos.h (scm_software_type): Declaration deleted.
2841 * script.c (scm_find_executable): Don't test if unix is #defined
2842 here; first, NetBSD doesn't #define it, and second, it's the wrong
2843 way to go about these things. (Thanks to Perry Metzger.)
2844 (dld_find_executable): Delete this MSDOS support code. This isn't
2845 the way we want to support this; it needs to be rethunk at a
2848 * genio.c (scm_do_read_line): Don't just politely check that the
2849 line was either non-empty or EOF. Abort if it's empty and not
2852 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2854 * scmconfig.h.in: Regenerated.
2856 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2859 * genio.c (scm_do_read_line): Count lines correctly when the file
2860 doesn't end in a newline.
2862 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2864 * genio.c (scm_do_read_line): Maintain the line count correctly.
2865 (Thanks to Harvey J. Stein and Greg Harvey.)
2867 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2870 * numbers.c (big2str): Protect t from garbage collection until
2871 we're done. (Thanks to Gary Houston.)
2873 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2875 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2877 * Makefile.in: Regenerated.
2879 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2880 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2883 Do magic to mix reads and writes on stdio FILE-based ports.
2884 (Thanks to Christian Lynbech.)
2885 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2887 (pre_read, pre_write): New functions.
2888 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2889 local_fputs): Call them.
2890 (local_fflush): Mark the port as ready for reading and writing.
2891 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2892 flags on new port objects. This might not be accurate --- who
2893 knows what state the FILE * is in when we get it --- but it won't
2894 do extraneous calls to fflush or fseek, so it's no worse than the
2895 behavior before this change.
2896 * ports.h: Add comment.
2898 Centralize the creation of port objects based on stdio FILE * in
2899 fports.c; don't just throw them together anywhere.
2900 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2901 what the rest of Guile wants. Don't set the revealed count;
2902 that's only appropriate for stdin, stdout, stderr.
2903 (scm_standard_stream_to_port): This function does set the revealed
2905 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2906 not scm_stdio_to_port.
2907 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2908 * fports.c (scm_open_file): Same.
2909 * posix.c (scm_pipe): Same.
2910 * socket.c (scm_sock_fd_to_port): Same.
2911 * ioext.c (scm_fdopen): Same.
2912 (scm_freopen): Moved from here to...
2913 * fports.c (scm_freopen): ... here. This is really something that
2914 munges the internals of an fport, so it should go here.
2915 * fports.h (scm_stdio_to_port): Adjust prototype.
2916 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2917 * ioext.h (scm_freopen): Prototype removed.
2919 * filesys.c (set_element, get_element): This can work on both pipe
2920 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2923 * scmconfig.h.in: Regenerated.
2925 Change the definition of the functions in scm_ptobfuns so that
2926 they get passed the port object, not the port's stream.
2927 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2928 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2929 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2930 Pass the port itself to the scm_ptobs function.
2931 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2932 scm_generic_fgets): Same.
2933 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2934 getc_void_port, fgets_void_port, close_void_port): Just change the
2935 argument names; these functions don't really do anything.
2936 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2937 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2938 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2939 Also, use prototyped definitions, and get rid of the extra
2941 (scm_fptob, scm_pipob): We don't need casts here any more.
2942 * strports.c (prinstpt): Use prototype declarations.
2943 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2944 and use SCM_STREAM to get the string info. Also, use prototyped
2945 definitions, and get rid of the extra declarations.
2946 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2949 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2950 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2952 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2953 scm_fgets, for consistency.
2954 (scm_fptop, scm_pipob): References updated.
2956 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2958 Include the source location in error messages for scripts.
2959 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2960 stack is still there when we catch the error.
2961 * throw.c (handler_message): If we are handling an error with a
2962 message, then put together the proper arguments and call
2963 scm_display_error, instead of scm_display_error_message. That
2964 displays source location, if it can find it.
2966 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2968 * gc.c (scm_unprotect_object): Change this so that calls to
2969 scm_protect_object and scm_unprotect_object nest properly.
2970 (scm_protect_object): Doc fixes.
2972 * strings.c (scm_string_set_x): Require the argument to be a
2973 writable string, not a substring or a symbol.
2974 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2975 (Thanks to John Redford and Charbel Jacquin.)
2977 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2979 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2981 * eval.c (safe_setjmp): Remove this misunderstanding.
2982 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2985 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2987 * libguile.h: Mark these as C declarations, for compilation by C++
2990 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2991 __cplusplus clause. I seriously doubt this ever worked the way
2992 the author seems to have intended.
2994 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2996 Utterly needless cleanups to hopelessly messy code.
2997 * ports.c: Doc fixes.
2998 (scm_fflush): Moved to ...
2999 * genio.c (scm_fflush): ... here, amongst all the other port
3000 method invocation functions.
3001 * genio.h, ports.h: The prototype moves too.
3003 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
3005 * backtrace.c (display_error_body): The current frame does not
3006 always have a parent frame; consider a function called directly
3007 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
3010 * alloca.c (alloca): Undo yesterday's changes, and simply call
3011 malloc directly for storage, and abort if we don't get what we
3012 want. The situation is much simpler --- just call malloc. Emacs
3013 has bizarre/evil requirements (signal handlers might malloc unless
3014 you set this global flag, so you have to set the flag around all
3015 calls to malloc) which we are certainly not going to conform to,
3016 so we can do the simple and obvious thing.
3018 * coop.c (coop_condition_variable_wait): Make this function
3019 static. It's only useful internally --- you should never just
3020 wait on a condition variable.
3021 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
3023 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3025 * unif.c (scm_array_set_x): Accept any kind of number as an
3026 element for a uniform vector of doubles. This is more consistent
3027 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
3029 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
3030 works; I can't conveniently test it myself. (Thanks to Dvid
3031 Tillman for the bug report.)
3033 * init.c: Doc fixes.
3035 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
3036 from here, not from scm_compile_shell_switches (which is a pretty
3037 dumb place to do it).
3038 (scm_load_startup_files): New function.
3039 (scm_ice_9_already_loaded): Variable moved to here from script.c.

3043 * init.c (scm_load_startup_files): Prototype for new function.
3044 * gh_init.c (gh_enter): Doc fix.
3046 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3048 Some anti-warning changes from Greg Harvey.
3049 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
3050 warnings when it doesn't understand our NORETURN declarations in
3052 * posix.c (scm_mknod): Similar.
3054 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3056 * posix.c (scm_getpwuid): If we can't find an entry, return our
3057 own message, instead of using scm_syserror --- the getpwMUMBLE
3058 functions don't set `errno' to anything interesting.
3060 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3062 Get rid of warnings from the cooperative threading system.
3063 * threads.h (scm_single_thread_p, scm_yield,
3064 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
3065 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
3066 scm_wait_condition_variable, scm_signal_condition_variable): Add
3067 prototypes for these Scheme-visible functions.
3068 * coop-defs.h (coop_next_runnable_thread,
3069 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
3070 Prototypes for these here, even though they're from iselect.c.
3071 (coop_condition_variable_wait, coop_join): Add prototypes.
3072 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
3073 scm_threads_free_condvar): Make these smob functions static.
3074 * coop-threads.h (coop_init): Give this a real prototype.
3075 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
3076 (coop_next_runnable_thread): No need to provide prototype; it's in
3079 * scmconfig.h.in: .detarenegeR
3081 * iselect.c, threads.c: Doc fixes.
3083 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3085 * Makefile.in: Regenerated with a patched automake, to get
3086 dependency generation right when using EGCS.
3088 * inet_aton.c (inet_aton): Add prototype, to remove compiler
3089 warning. (Thanks to Robert Pluim.)
3091 * inet_aton.c (inet_aton): Reassure the compiler that the
3092 arguments to the <ctype.h> macros are all unsigned characters, not
3095 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3097 Getting rid of more warnings...
3098 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
3099 today's change to ../configure.in.
3100 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
3101 * scmconfig.h.in: Regenertaded.de.,.__
3102 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
3103 (scm_localtime, scm_mktime): Use a const char * to manipulate the
3106 * readline.c: Doc fix.
3107 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
3108 * readline.h (scm_filename_completion_function): Add prototype.
3109 (scm_init_readline): Make this into a prototype.
3111 * readline.c (scm_filename_completion_function): Use SCM_PROC to
3112 declare this, instead of calling scm_make_subr manually.
3114 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
3116 * readline.h (scm_init_readline): Add prototype for this.
3117 (scm_init_readline): Make this a real prototype.
3119 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3121 Warning fixes from Maciej Stachowiak:
3122 * backtrace.h (scm_display_application, scm_backtrace): Add
3124 * debug.c (scm_m_start_stack): Make this function static.
3125 * fluids.h (scm_fluid_p): Add prototype.
3126 * procprop.c (scm_i_procedure_arity): Make this function static.
3127 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3128 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
3129 * root.h (scm_dynamic_root): Add external prototype.
3130 * scmsigs.h (scm_usleep): Add external prototype.
3131 * script.h (scm_init_script): Use prototype, not K&R decl.
3132 * stacks.h (scm_stack_id): Add external prototype.
3133 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3135 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3137 * gh.h: took out the definitions of vset and vref, since they are
3138 replaced by the proper vector routines that correspond to the R4RS
3141 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3143 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3144 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3145 third argument, a C expression that should result in a SCM value,
3146 which is used to initialize the variable. Reimplemented
3147 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3150 * version.h (scm_libguile_config_stamp): Add prototype.
3151 (From Maciej Stachowiak.)
3153 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3155 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3156 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3158 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3160 * print.c (scm_iprin1): Rather than having one i, and using it in
3161 several places, declare a fresh i local to each block where it is
3162 used, and give it a signedness appropriate to its use in each case.
3163 (scm_iprlist): Same.
3165 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3166 comparison warnings.
3168 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3169 signed/unsigned clashes.
3171 * posix.h (scm_tmpnam): Added prototype.
3173 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3174 scm_make_subclass_object): Add external prototypes.
3176 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3177 comparison is okay here.
3179 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3181 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3182 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3184 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3187 * load.c (swap_port): Make this function static.
3189 * load.c (scm_search_path): Make max_path_len and max_ext_len
3190 unsigned, since they're compared against string sizes.
3192 * load.c (init_build_info): Make i unsigned.
3194 * ioext.h (scm_read_line): Add prototype.
3196 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3197 scm_hash_fn_remove_x): Make hash bucket index local variable k
3198 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3199 accurately as possible.
3201 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3202 comparisons, and range checking to make sure those casts are
3205 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3206 signed/unsigned comparisons.
3208 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3209 avoid signed/unsigned comparisons.
3210 * smob.h (scm_numsmob): Change extern declaration to match.
3212 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3213 avoid signed/unsigned comparisons.
3214 * ports.h (scm_numptob): Change extern declaration to match.
3215 (scm_current_load_port, scm_set_port_line_x,
3216 scm_set_port_column_x): New prototypes.
3218 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3219 test code, and it causes warnings.
3221 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3222 gh_uniform_vector_ref): Added prototypes.
3224 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3225 debugging support unconditionally. That's backtrace.c, stack.c,
3226 debug.c, and srcprop.c.
3227 (EXTRA_libguile_la_SOURCES): Omit those from here.
3228 * Makefile.in: Regenerated.
3230 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3232 * options.c (scm_options): Bugfix: Allow empty list of options!
3234 * debug.c, debug.h (scm_single_step): Removed.
3235 (scm_with_traps): New procedure. This procedure could easily be
3236 written in Scheme but needs to be highly optimized.
3238 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3240 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3241 Check SCM_TRAPS_P before trapping.
3243 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3245 Changes to avoid signed/unsigned comparison warnings.
3246 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3247 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3248 so they can have appropriate types for each application. Make i
3249 signed. Use initializers in some spots. I'll probably pay for
3251 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3252 (scm_must_realloc): Make nm unsigned.
3253 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3254 (scm_init_storage): Use prototype-style definition, and make the
3256 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3257 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3259 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3260 avoid signed/unsigned comparison warnings, and because the return
3261 value of readlink may be -1. Don't bother casting the third
3262 argument to readlink.
3264 * filesys.c (scm_dirname, scm_basename): Move these to their own
3265 page, at the end of the file.
3266 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3268 * eval.h (scm_eval_options_interface): Add external prototype for this.
3269 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3271 * eval.c (scm_lookupcar1): Make this static.
3273 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3274 Make these prototype declarations, not K&R-style.
3276 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3277 unsigned comparison warning.
3279 * appinit.c: File removed. It had a single function in it, empty,
3280 whose reason for existence is explained in no documentation or
3281 comment. I think it's there as a default for some Tcl-style
3282 initialization, but Tcl abandoned that approach a while ago.
3283 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3284 (BUILT_SOURCES): Remove appinit.x.
3285 * Makefile.in: Regenerated.
3287 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3289 * Makefile.in: Regenerated using the last public version of
3290 automake, not the hacked Cygnus version.
3292 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3294 Remove Totoro kludge.
3295 * Makefile.in, scmconfig.h.in: Regenerated.
3296 * init.c, readline.c: Don't check if TOTORO is #defined.
3298 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3300 * Makefile.am: Adjust for new thread configuration system.
3301 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3302 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3304 (THREAD_LIBS): Definition deleted; automake will generate such
3305 things automatically.
3306 * Makefile.in: Regenerated.
3308 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3310 Simplify smob and port marking; set the mark bit in the generic
3311 marking code, and make marker routines only responsible for
3312 turning up outgoing pointers.
3313 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3314 before calling the marking function. Don't call the marking
3315 function if it's zero.
3316 * markers.c (scm_mark0): Just return #f. This function isn't
3317 necessary at all now, but it's harmless to call it. We'll leave
3318 it in so other folks' code doesn't croak at link time.
3319 (scm_markcdr): Don't call SCM_SETGC8MARK.
3320 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3321 * dynl.c (mark_dynl_obj): Same.
3322 * root.c (mark_root): Same.
3323 * srcprop.c (marksrcprops): Same.
3324 * unif.c (markra): Same.
3325 * variable.c (scm_markvar): Same.
3326 * ports.c (scm_markstream): Same.
3327 (void_port_ptob): Specify zero for our marking function.
3328 * debug.c (debugobjsmob): Same.
3329 * dynwind.c (guardsmob): Same.
3330 * filesys.c (dir_smob): Same.
3331 * fluids.c (fluid_smob): Same.
3332 * fports.c (scm_fptob, scm_pipob): Same.
3333 * mallocs.c (mallocsmob): Same.
3334 * regex-posix.c (regex_t_smob): Same.
3335 * smob.c (freecell, flob, bigob): Same.
3336 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3337 * throw.c (jbsmob, lazy_catch_funs): Same.
3339 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3341 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3342 scm_copy_tree on code in order not to let memoized code to leak
3343 out. Thus, scm_copy_tree needs to copy vectors as well since
3344 quasiquote can introduce evaluated code also inside vector
3347 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3349 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3351 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3352 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3355 * unif.c: Say that ivect and uvect are of type signed and unsigned
3356 long instead of int in commentary so that it correctly describes
3359 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3361 * stime.c: Removed declaration of strptime. (It should be
3362 declared by the system headers. If it turns out that some systems
3363 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3365 * stime.h: Renamed TIMEH --> STIMEH
3367 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3368 to increase portability, don't use structure assignment.
3369 (Thanks to Nicolas Neuss.)
3371 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3373 (finalize_fd_sets): Added empty statement after last case label.
3374 (Thanks to Nicolas Neuss.)
3376 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3379 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3381 * init.c, readline.c: OK, I won't have these readline.x bug
3382 reports anymore. We've had them since April. The current reason
3383 is a completely unintelligible failure of totoro.red-bean.com to
3384 do the test for rl_getc_function in libreadline correctly. This
3385 kludge overrides the test if we're on totoro so that the snapshot
3386 generation process can work.
3388 * readline.c: Define a strdup replacement if not existent on system.
3390 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3392 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3393 This change makes scm_make_vector R5RS compatible. We cannot keep
3394 the third argument since people want to be able to deduce the form
3395 of the C function call only by looking at R5RS. (At the same time
3396 we have removed some unnecessary complexity!)
3398 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3399 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3400 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3401 argument in call to scm_make_vector.
3403 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3405 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3406 This macro is useful in applications.
3408 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3410 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3411 (scm_parse_path, scm_search_path): New Scheme level procedures.
3413 * load.h (scm_internal_parse_path, scm_parse_path,
3414 scm_search_path): Declared.
3416 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3418 * filesys.c (dirname, basename): New procedures.
3420 * init.c (scm_boot_guile_1): Removed condition around
3423 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3424 new data type (guards) for representation of C level guards and
3425 data on the wind chain.
3426 (scm_internal_dynamic_wind): New function.
3428 * dynwind.h: Declare scm_internal_dynamic_wind.
3430 * root.h (scm_root_state): Added scm_cur_loadp.
3432 * root.c (mark_root): Added comment about cur_loadp.
3434 * load.c: #include "dynwind.h";
3435 (scm_primitive_load): Use scm_inner_dynamic_wind to update
3438 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3440 * ports.c (current-load-port): New procedure.
3442 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3444 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3445 not a tty, return #f.
3447 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3448 to Julian Satchell and Roland Kaufmann.)
3450 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3451 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3453 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3455 * debug.h, debug.c (scm_start_stack): New function. Implements
3456 the guts of old scm_m_start_stack.
3458 * debug.c (scm_m_start_stack): Use scm_start_stack.
3460 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3461 start_stack and restart_stack. (These have static scope.)
3463 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3465 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3466 readline functions to come in release 2.3. (Thanks to Chet
3468 (handle_errors): Use the above functions.
3470 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3472 * readline.c: Improvements for readline support: Handle errors
3473 better; Implement before-read-hook.
3475 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3477 * init.c (scm_boot_guile_1), readline.c: Test for
3478 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3479 assure that we have version >= 2.1.)
3481 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3483 * readline.c (scm_readline): Defer interrupts while we're calling
3486 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3487 away the string to add_history.
3488 (completion_function): Do completion for readline. (Thanks to
3490 (scm_filename_completion_function): New procedure: Filename
3492 (current_input_getc): New function. Use this one instead of
3493 standard getc from readline.
3495 * throw.c, throw.h (scm_handle_by_throw): New function: This
3496 handler throws errors to next handler on the dynwind chain.
3498 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3500 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3503 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3505 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3507 (scm_procedure_properties): Modified to return arity together with
3509 (scm_procedure_property): Added the read-only property `arity'.
3510 (scm_set_procedure_property_x): It is an error to set the `arity'
3513 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3514 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3516 * procprop.h (scm_sym_arity): New symbol.
3518 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3519 to set the dispatch procedure of an operator or entity object.
3521 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3522 Made procedure slots read-only.
3524 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3525 scm_tcs_cons_gloc case in zero args switch; Fixed args
3526 construction for operators in scm_tcs_cons_gloc case in two args
3529 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3531 * fluids.c: Removed use of assert.h (in order to avoid
3534 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3536 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3538 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3539 change makes the evaluator safer at the cost of evaluation speed.
3540 It handles the case when the user has added a non-immediate
3541 improper end of the application form, e.g., `(+ 0 . x)'.
3542 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3543 minimize the extra cost as much as possible. The new code is
3544 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3545 problem with structs planted directly in the code (e.g. by a
3546 macro). This no longer causes segmentation fault. (Thanks to
3549 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3550 arg `proc' in order to be able to throw errors; New argument
3553 * Removed extra #include "debug.h"
3555 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3557 * scmsigs.c: Declare usleep as returning void on some systems.
3558 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3561 * coop.c (usleep): Return void on some systems.
3563 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3565 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3567 * coop.c: Changed return type of usleep to int.
3569 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3570 isn't found in the OS.
3572 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3573 isn't enabled. (Thought that I had made this change ages ago...)
3575 * iselect.c: Declare bzero if not defined by OS.
3577 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3579 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3580 condition. (Thanks to John Tobey.)
3582 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3583 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3586 * __scm.h: Start the long-term project of moving to POSIX threads.
3587 Phase 1: Classification of all critical sections.
3588 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3589 for A sections. (See comments in __scm.h for details.)
3591 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3592 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3594 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3596 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3597 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3598 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3599 dependencies on $(srcdir)/Makefile.in
3600 $(top_builddir)/config.status in order to avoid circularity.
3602 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3603 from argc if argc was 0 initially.
3605 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3606 in generation of libpath.h.
3608 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3610 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3611 libguile from 2 to 3.
3613 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3615 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3617 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3619 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3620 scm_set_port_column_x, scm_port_filename,
3621 scm_set_port_filename_x): Removed optional arguments. Added
3622 proper argument checking.
3624 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3625 stack size in machine words.
3627 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3628 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3629 to Ole Myren Röhne.)
3631 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3633 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3634 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3636 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3639 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3640 procedure apply: Copy argument lists before pushing them unto the
3641 environment so that the environment won't get mutated due to
3642 manipulation of procedure arguments. This should perhaps be
3643 regarded as a temporary solution until someone finds a more
3644 efficient one. (Thanks to Maciej Stachowiak.)
3646 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3648 * script.c (scm_compile_shell_switches): Use "guile" as default
3649 zero arg if argc is NULL.
3651 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3653 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3654 is zero. (Thanks to Dirk Herrmann.)
3656 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3658 * ports.c (scm_add_to_port_table): First line is now line 0
3659 (was 1). (Interface changed according to suggestion by Per
3662 * backtrace.c (display_header): Add 1 to line and column numbers
3663 when presenting them to the user.
3665 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3666 from debug.c --> eval.c
3668 * eval.h, eval.c (scm_eval_options_interface): New options
3670 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3671 i.e. stacks for new threads.
3673 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3675 * eval.c (unsafe_setjmp): Removed with #if 0.
3677 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3680 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3681 to avoid compiler warnings.
3683 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3685 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3687 * throw.c (handler_message): Print message on current error port
3688 instead of default error port. (Thanks to Maciej Stachowiak.)
3690 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3692 * ports.c (scm_add_to_port_table): allocate in units of
3693 struct scm_port_table *, not struct scm_port_table.
3694 * posix.c (scm_close_pipe): remove the port from the port table
3696 Thanks to Rob Engle for both fixes.
3698 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3700 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3701 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3703 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3705 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3707 * backtrace.c (display_error_body, display_backtrace_body),
3708 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3709 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3710 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3711 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3714 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3715 don't receive the jmpbuf arg anylonger.
3716 (scm_catch): Don't accept a #f tag.
3717 (scm_throw): Check that key is a symbol.
3718 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3720 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3722 * async.c (async_pending): Removed declaration.
3724 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3726 * dynwind.c (scm_wind_chain): New debug function.
3728 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3729 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3730 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3731 extra layer of functions around the body and handler of a thread.
3732 This extra layer makes sure that the handler is called in the
3733 dynamic context of the surround (= empty dynwind list), but under
3734 the *dynamic root* of the body. We can not use the dynamic root
3735 of the surround since that root belongs to another thread => stack
3736 is not handled correctly. It may seem ugly to use this extra
3737 layer, but the extra cost in terms of execution time is really
3738 negligible compared to the total amount of time required to create
3739 a thread, and it would reduce maintainability to duplicate the
3740 crucial and complicated steps performed by cwdr.
3742 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3743 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3744 get re-enabled. The important effect of this is that interrupts
3745 are blocked during thread switching so that thread data structures
3746 don't risk getting messed up by an unfortunate signal.
3747 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3748 seems to do more aggressive optimization which actually move
3749 instructions around in these macros in a fatal way. Therefore:
3750 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3751 just superstitious...)
3752 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3753 This macro should be used instead of SCM_ASYNC_TICK since the
3754 latter doesn't do context switches any more.
3756 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3757 instead of SCM_ASYNC_TICK.
3759 * coop.c, iselect.c: Since thread switches are now performed with
3760 interrupts masked, we can't use the old mechanism of delivering
3761 signals immediately when they arrive. Signals must instead be
3762 delivered when the asyncs run *after* the end of the critical
3763 section in scm_internal_select. But this also means after context
3764 switch so that the signal will be delivered to a different thread.
3765 To avoid this, I have changed the protocol of
3766 coop_wait_for_runnable_thread and friends so that they are allowed
3767 to return the original thread. So, if a signal arrives during
3768 scm_internal_select, we won't any longer be forced do a context
3769 switch, but can remain in the same thread and deliver the signal
3772 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3773 scm_asyncs_pending and made it global.
3775 * iselect.c: Small fixes.
3777 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3778 coop_condition_variable_init, coop_condition_variable_wait,
3779 coop_condition_variable_signal): Changed return type from `void'
3780 to `int'. This is to adhere closer to the pthreads interface.
3781 This, in turn, is part of an attempt to provide C versions of the
3782 mutex and condition variable primitives which can be part of a
3783 frontend to COOP or pthreads.
3785 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3786 coop_condition_variable_destroy): New functions.
3788 * coop-threads.c (scm_wait_condition_variable): Use
3789 coop_condition_variable_wait_mutex.
3791 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3792 Definitions moved to coop-defs.h.
3794 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3795 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3796 scm_cond_destroy): New C interface to mutecis and cond vars.
3798 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3800 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3802 * iselect.c: Now several threads can wait on the same file
3803 descriptor. The behaviour is compatible with OS select: All
3804 threads waiting for the fd return with the same status.
3806 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3808 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3809 Can spawn a thread from application C code.
3811 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3813 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3814 gh_doubles2scm): New functions.
3816 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3818 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3819 commented-out version of gh_eval_str()
3821 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3823 * socket.c (scm_bind): free soka after use.
3825 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3827 * stime.c (tzvar): new variable.
3828 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3829 avoid memory leaks when allocating.
3831 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3833 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3836 * gc.c, tags.h: Doc fixes.
3838 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3840 * eval.c (macro-eval!): Removed. This function was a design bug.
3841 It allowed memoized code to leak out to the scheme level. Most
3842 things that you could do with `macro-eval!' can be done with
3845 1997-12-20 Tim Pierce <twp@skepsis.com>
3847 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3848 scm_fgets now depends on ftell(3) to know how many bytes were
3851 1997-12-15 Tim Pierce <twp@skepsis.com>
3853 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3854 dealing with strings.
3856 1997-12-13 Tim Pierce <twp@skepsis.com>
3858 Make %read-line more suitable for implementing read-line efficiently.
3859 * ioext.c (scm_read_line): Strip the terminating newline from a
3860 string, and return a cons of the string and its terminator.
3862 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3863 of the string that is read is stored in this memory location.
3864 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3865 * genio.c, genio.h (scm_do_read_line): Update caller.
3866 * ports.h (scm_ptobfuns): Update typedef.
3867 * fports.c (scm_fptob, scm_pipob): Update struct.
3869 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3871 * filesys.c (set_element): Return file descriptor.
3872 (fill_select_type): Return the highest file descriptor.
3873 (scm_select): Tell select about the highest file descriptor. On
3874 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3875 Therefore the extra overhead for calculating the maximum fd seems
3876 to be more than compensated. Is this correct? In any case,
3877 scm_internal_select will be much faster with this info.
3878 (scm_select, fill_select_type, set_element): Don't accept any kind
3879 of object in the file descriptor list or vector.
3881 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3883 * iselect.c (finalize_fd_sets): Bugfix.
3885 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3887 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3888 when using scm_internal_select (since we might switch to another
3891 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3893 * simpos.c (scm_system): always define: use sysmissing if not
3894 available. Check for HAVE_SYSTEM instead of _Windows (does
3895 Windows lack system or does it have an unusable one?).
3896 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3897 Let the argument be optional: if not supplied, call system(NULL).
3899 * ports.c (scm_close_port): relax the type check from OPPORTP to
3900 PORTP; closing a closed port is allowed.
3902 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3904 * fports.c (scm_fgets): Return if the last char in a chunk is
3905 newline. When fgets returns a string whose length is `size-1', it
3906 is ambiguous whether a whole line was retrieved, so we must check
3907 explicitly whether a line terminator is present.
3909 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3911 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3912 before taking the CDR. (Thanks to Harald Meland.)
3914 * filesys.c (scm_stat): Slightly optimized.
3916 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3918 * ports.c (scm_close_port): Make sure the port is open before
3921 * guile-snarf.in: Pass args through to gcc in a way that preserves
3922 whitespace boundaries. (Thanks to Greg Badros.)
3924 1997-12-02 Tim Pierce <twp@skepsis.com>
3926 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3927 statement. (Thanks to Doug Evans for pointing this out.)
3929 1997-12-01 Tim Pierce <twp@skepsis.com>
3931 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3933 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3935 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3936 errno macro expansion of this field name. (errno is a C
3937 preprocessor macro on some systems.)
3939 1997-11-29 Tim Pierce <twp@skepsis.com>
3941 * iselect.c: Doc fix.
3943 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3945 * init.c (scm_start_stack): Removed initialization of
3946 scm_the_last_stack_var.
3948 * backtrace.h: Declare scm_the_last_stack_var.
3950 * backtrace.c: Define scm_the_last_stack_var.
3952 * root.c (mark_root): Don't mark the_last_stack_var.
3954 * root.h (scm_root_state): Removed the_last_stack_var.
3956 * throw.c: Added #include "fluids.h"
3957 (ss_handler): `the-last-stack' is now a fluid.
3959 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3960 --> the_last_stack_fluid.
3962 * backtrace.c: Added #include "fluids.h"
3963 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3964 (scm_backtrace): `the-last-stack' is now a fluid.
3966 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3967 after scm_init_fluids.
3969 1997-11-28 Tim Pierce <twp@skepsis.com>
3971 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3973 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3974 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3976 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3978 * iselect.c (coop_next_runnable_thread,
3979 coop_wait_for_runnable_thread): Disable interrupts so that no
3980 async is executed before a potential error_revive.
3981 (scm_internal_select): Disable interrupts during the parts of the
3982 code which manipulate the sleep queue and the file descriptors.
3984 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3986 * Makefile.am: Added iselect.c and iselect.h.
3988 * coop.c (coop_qinit): Initialize fields used by
3989 scm_internal_select.
3990 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3991 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3992 replacement in iselect.c.
3993 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3994 coop_join): If GUILE_ISELECT enabled, use
3995 coop_wait_for_runnable_thread instead of
3996 coop_next_runnable_thread.
3997 (usleep, sleep): New replacements for system functions if
3998 GUILE_ISELECT is enabled.
4000 * coop-threads.h: Declare coop_wait_for_runnable_thread.
4002 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
4004 * filesys.c: Added #include "iselect.h". Moved FD-macros to
4005 iselect.h. Implement Scheme level `select' using
4006 scm_internal_select. (See NEWS.)
4008 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
4010 * init.c: Call scm_init_iselect.
4012 * iselect.h, iselect.c: New files. Implements
4013 scm_internal_select. (See NEWS.)
4015 1997-11-27 Tim Pierce <twp@skepsis.com>
4017 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
4018 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
4019 and scm_must_free, since ultimately the string returned will be copied
4020 by scm_makfrom0str anyway. Also, read any characters that may have
4021 been pushed onto the port with scm_ungetc.
4022 * ports.c (scm_generic_fgets): Same as for scm_fgets.
4023 * ioext.c (scm_read_line): Free string after Guilifying it.
4024 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
4026 1997-11-26 Anthony Green <green@hoser.cygnus.com>
4028 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
4030 * gh.h: Safely wrap prototypes for c++ usage.
4032 1997-11-25 Mark Galassi <rosalia@cygnus.com>
4034 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
4035 gh_repl (argc, argv).
4037 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
4039 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
4040 and to invoke scm_shell().
4041 (gh_launch_pad): took out the loading of boot-9.scm from here,
4042 since it is probably best to let the user control that. In fact,
4043 gh_repl() now invokes scm_shell() which does that.
4045 1997-11-23 Mark Galassi <rosalia@cygnus.com>
4047 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
4050 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
4052 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
4053 yesterday's underscore patch. (Thanks to Marius Vollmer for
4056 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
4058 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if

4069 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
4070 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
4072 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
4074 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when

4082 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
4084 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
4085 OPORT is an `open' port, not an output port.
4087 * filesys.c (scm_close, set_element, get_element, scm_chown,
4088 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

4094 scm_close_all_ports_except, scm_set_current_output_port,
4095 scm_set_current_error_port): Likewise
4096 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
4097 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):

4105 * unif.c (scm_uniform_array_write): Likewise
4107 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
4109 Minor problems with substring-related tag changes.
4110 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
4111 exactly what we want to leave in to detect substrings.
4112 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
4113 * tags.h: Fix diagrams and comments describing the S tag bit;
4114 remove vestigial remarks about the D tag bit.
4115 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
4116 * strings.c: Formatting tweaks.
4118 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
4119 variable first; then SCHEME_LOAD_PATH, with a warning message.
4120 (scm_parse_path): New function.
4121 * script.c: Doc fixes.
4123 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
4125 Readline support, from Daniel Risacher.
4126 * readline.c, readline.h: New files.
4127 * init.c: #include "readline.h".
4128 (scm_boot_guile_1): Call scm_init_readline, if we have it.
4129 * Makefile.am (libguile_la_SOURCES): Include readline.c.
4130 * Makefile.in: Regenerated.
4131 * scmconfig.h.in: Regenerated, after change to ../configure.
4133 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4135 * gh.h: gh_vector_set -> gh_vector_set_x
4137 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4139 * gh_data.c (gh_vector_set_x): changed name to make it consistent
4140 with the ! -> _x mapping when going from Scheme to C.
4142 1997-10-19 Mark Galassi <rosalia@cygnus.com>
4144 * gh.h (gh_reverse):
4152 (gh_assoc): added these gh_ functions implemented as macros.
4154 * gh_predicates.c (gh_null_p):
4155 (gh_string_equal_p): added these two missing predicates.
4157 * gh_list.c (gh_append):
4162 (gh_set_cdr_x): added these routines as I go through and try to
4163 complete the picture R4RS functions that should be mirrored in the
4166 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4168 * tags.h (scm_tc7_substring): Changed the comment and code to
4169 conform with the changes below. Folks! We have suddenly two new
4170 free tc7 codes!!! Jummy, jummy!
4172 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
4174 * Makefile.in: Rebuilt.
4175 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
4177 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.

4195 (scm_tc7_mb_string): Removed.
4196 (scm_tc7_mb_substring): Removed.

4199 Don't include "mbstrings.h".
4200 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
4201 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
4203 Don't include "mbstrings.h".
4204 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
4205 (SCM_SYMBOL_SLOTS): Define as 4.

4227 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
4228 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
4230 1997-10-12 Mark Galassi <rosalia@cygnus.com>
4232 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
4234 * gh_test_c.c (c_vector_test): some improvements on the vector
4237 * gh.h (gh_vector): this used to exist but do the wrong thing.
4238 Now it (almost) does the right thing, though it takes a list
4239 instead of the individual arguments. I need to see how it could
4241 (gh_list_to_vector): added this function as a macro. Corresponds
4242 to Scheme's (list->vector ...).
4243 (gh_vector_to_list): added this function as a macro. Corresponds
4244 to Scheme's (vector->list ...).
4246 * gh_data.c (gh_vector_ref): renamed from gh_vref to
4247 gh_vector_ref, so that it resembles the Scheme routines more.
4248 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
4249 resembles the Scheme routines more.
4250 (gh_make_vector): this used to be (stupidly) called gh_vector().
4251 This is the right name, since it does the same thing as the Scheme
4252 (make-vector ...) procedure.
4254 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4256 * ports.h: #include "libguile/print.h"
4258 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
4259 Some indentation fixes.
4261 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
4262 longer a user field; New field: class_flags.
4264 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
4266 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
4268 * gh_data.c (gh_bool2scm): new function which replaces
4269 gh_int2scmb(), which is now tagged as obsolete.
4271 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4273 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4274 macros should by convention not test for NIMPness.)
4275 (SCM_COERCE_OPORT): Adjust indentation.
4277 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4278 SCM_NIMP test before SCM_PRINT_STATE_P.
4280 * struct.c, struct.h, gc.c: Renamed:
4281 scm_struct_i_layout --> scm_vtable_index_layout
4282 scm_struct_i_vcell --> scm_vtable_index_vcell
4283 scm_struct_i_vtable --> scm_vtable_index_vtable
4284 scm_struct_i_printer --> scm_vtable_index_printer
4285 scm_struct_i_vtable_offset --> scm_vtable_offset_user
4287 * struct.c (scm_print_struct): Use new printer slot; Default
4288 printing: Also output hex code of vtable so that type identity
4289 will be indicated as well.
4290 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4291 Removed struct_printer_var; Removed struct-vtable-offset;
4292 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4293 vtable-offset-user): New constants.
4295 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
4296 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
4297 If this slot contains a procedure, use that to print structures of
4298 the type represented by this vtable.
4300 * print.c (scm_iprin1): Don't print arguments of macro
4301 transformers. (They are always: exp env.); Bugfix: Unmemoize
4302 transformer source with correct environment.
4304 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4306 Streamlining of call-with-dynamic-root:
4308 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
4309 there is now only one catch.
4310 (cwdr_outer_body): Removed.
4311 (cwdr_handler): New function.
4312 (scm_internal_cwdr): New function to perform the function of cwdr
4313 but take args that are more useful to C code. Also, the handler
4314 is now invoked *outside* of the new dynamic root, like the docs
4315 say. We no longer have to catch absolutely all errors, the caller
4316 is responsible for using a handler that does not throw, if he
4318 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4319 * root.h (scm_internal_cwdr): New prototype.
4321 Even more but risky streamlining:
4323 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4324 allocation of the jumpbuf of a root continuation. The changes
4325 below are controlled by it. They are now deactivated.
4326 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4327 the JMPBUF of the scm_rootcont to NULL before returning.
4329 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4330 when they are non-NULL.
4331 (scm_gc_mark): Likewise, mark only when non-NULL.
4333 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4334 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4336 * gc.c (scm_done_malloc): New function.
4337 gc.h (scm_done_malloc): New prototype.
4339 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
4340 (struct scm_print_state) [revealed]: New field.
4341 (scm_print_state_vtable): Make visible to the outside world for
4342 type checking purposes.
4343 (scm_valid_oport_value_p): New prototype.
4345 * print.c (scm_valid_oport_value_p): New function to check whether
4346 a certain value is acceptable as a port argument.
4347 (scm_print_state_vtable): New variable.
4348 (scm_free_print_state): Set `revealed' field to false.
4349 (scm_iprin1): Call user supplied closure printer with
4350 scm_printer_apply. Print in the traditional way when there isn't
4351 one or when it returns #f.
4352 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4353 Accept a port/print-state pair in addition to just a port.
4354 (scm_prin1): Don't return the print_state to the pool when it has
4356 (scm_printer_apply): Set `revealed' field of print_state to true.
4357 (scm_init_print): Set scm_print_state_vtable.
4358 (print_state_fluid, print_state_fluid_num): Removed.
4360 * throw.h (scm_handle_by_proc_catching_all): New prototype
4361 throw.c (scm_handle_by_proc_catching_all): New function
4363 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4365 * Makefile.in: Regenerated with automake 1.2c.
4367 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4369 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4370 was looping endlessly.
4372 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4374 * strports.c (scm_eval_string): Don't close the port.
4376 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4377 former returns a nice normal integer. (Thanks to Daniel
4380 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4382 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4383 makefile variable as a build parameter called LIBS. The
4384 build-guile program will use this, for the time being.
4385 * Makefile.in: Regenerated.
4387 Thanks to Shiro Kawai:
4388 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4389 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4392 * Makefile.in: Regenerated with automake 1.2a.
4394 * script.c (scm_compile_shell_switches): If we hit the -c or --
4395 arguments, don't set the car of (command-line) to scm_usage_name,
4396 the prettified name of the guile executable; give it the full
4397 path, the way shells usually handle $0.
4399 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4401 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4402 Scheme-level name `array-map' and renamed `serial-array-map' to
4403 `serial-array-map!'.
4405 * backtrace.c: Introduced exception handlers which now enclose
4406 `display-error' and `display-backtrace' so that error reporting
4407 won't get into infinite loops if an error occurs during displaying
4408 of the error. This can very easily happen with user supplied
4409 print call-back routines.
4411 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4413 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4414 the names `serial-array-map' and `array-map' should be removed.)
4416 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4418 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4419 Added #include "objects.h"
4421 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4422 Add #include "feature.h".
4424 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4425 (modinclude_HEADERS): Added objects.h.
4427 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4428 This test is needed at many places in the code and should be
4429 abstracted. (Motivated by the need of this test in libguiletk.)
4431 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4432 (scm_eval_string), load.c (scm_primitive_load,
4433 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4434 Use SCM_EOF_OBJECT_P.
4436 * eval.c (scm_init_eval): Add feature `delay'.
4438 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4440 * scmhob.h: Removed.
4442 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4444 * list.h (SCM_LISTn): New macros. Make list creation in C code
4445 prettier. The idea comes from STk.
4447 * sequences.h, sequences.c, append.h, append.c: Removed. These
4448 files implemented non-R4RS operations which would encourage
4449 non-portable programming style and less easy-to-read code.
4451 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4454 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4455 sequences.h, #include append.h.
4457 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4460 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4462 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4464 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4466 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4468 * eval.c: Added #include "objects.h"
4470 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4473 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4474 adjacent smob numbers.
4476 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4478 * procprop.h: Added declaration of scm_i_inner_name.
4480 * gsubr.c: New global symbol scm_i_inner_name.
4482 * debug.c (scm_procedure_name): Try procedure property
4483 `inner-name' if `name' fails.
4485 * print.c (scm_iprin1): Use scm_macro_name.
4487 * eval.c (scm_m_define): Give names to macros as well; Only the
4488 first top-level definition gives a procedure/macro a name.
4489 Otherwise confusing names can turn up in backtraces.
4490 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4491 `name'; Give names to macros as well.
4493 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4494 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4497 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4499 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4501 (prinmacro): Removed. The code has been moved/merged into print.c
4502 in order to decrease code redundancy. We want macros to print in
4503 a way equivalent to procedures, and it would be silly to duplicate
4504 the required code. (We don't want to maintain two places.)
4505 (macrosmob): Print field is now a NULL pointer.
4507 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4508 scm_macro_transformer): New prototypes.
4509 (scm_tc16_macro): Declared.
4511 * print.c (scm_iprin1): Added code for printing of macros. Macros
4512 are now printed in a way equivalent to procedures.
4514 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4516 * procs.h (scm_closure_p): Added declaration.
4518 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4520 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4521 Shouldn't pass "heap" as the subr name.
4523 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4525 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4526 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4527 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4528 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4529 SCM_BOOL_T. Any non-false value is true.
4531 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4533 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4534 scm_gensym): Added prototypes.
4536 * symbols.c (scm_gensym): New function. This will speed up
4537 certain types of applications (such as macro systems) which
4538 generate lots of symbols.

4546 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4547 specifier, since (2) or (2 . 3) would cause SEGV.
4548 (scm_transpose_array): more argument checking fixes.
4550 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4552 * Makefile.in: Regenerated.
4554 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4556 * Makefile.in: Regenerated, so it uses "tar", not "gtar".

4560 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4562 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4564 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4565 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4568 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4569 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4570 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,

4576 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4578 * errno.h: prototype for scm_strerror.
4579 * error.c (scm_strerror): new procedure.
4581 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4583 * list.c (scm_list_append_x): Allow non-pair as last argument.
4584 This is consistent with the R4RS append and is probably the
4585 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4587 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4589 * stime.h: prototype for scm_times.
4590 * stime.c (scm_times): new procedure.

4607 third argument is now optional.
4609 * posix.c (scm_execl, scm_execlp): make the filename argument
4610 compulsory, since omitting it causes SEGV.
4611 (scm_sync): return unspecified instead of #f.
4612 (scm_execle): new procedure.
4613 (environ_list_to_c): new procedure.
4614 (scm_environ): use environ_list_to_c. disable interrupts.
4615 (scm_convert_exec_args): take pos and subr arguments and
4616 improve error checking.
4618 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4620 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4621 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4622 argument to SCM_ASSERT. Furthermore, the name of the function
4623 should be passed as first argument when signalling
4624 SCM_WNA. (Thanks to Thomas Morgan)
4626 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4627 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4628 dispatches on the number of actual args has a default case
4629 reporting an internal error. This is a vestige from a version
4630 that mallocated a SCM vector to hold the arguments. In the
4631 current version this check is too late: if it ever happens we will
4632 have already overstepped the bounds of the array.
4634 Also, the patch [...] adds a check for too many actual arguments."
4636 mdj: Removed check for "internal programming error".
4638 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4640 * gh_io.c (gh_write): New function.
4642 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
4643 throw.c (scm_internal_stack_catch): New sibling to the other catch
4644 functions. Code moved from gh_eval.c.
4645 throw.h: Added header.

4653 Scheme name is now dup->fdes.
4654 (scm_dup_to_fdes): make the second argument optional and
4655 fold in the functionality of scm_primitive_dup.
4656 (scm_primitive_dup): deleted.
4658 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4660 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
4661 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4662 ultrix are defined. Use setvbuf instead of setbuf.
4663 (scm_setvbuf): new procedure.

4677 state as nested data while they are printed.
4678 (print_state_fluid, print_state_fluid_num): New variables.
4679 (scm_init_print): Initialize them.
4680 (scm_iprin): If print_state_fluid carries a print_state, use that
4681 instead of creating a new one.
4682 (scm_printer_apply, apply_stub, struct apply_data): New
4683 definitions to help with calling printer functions written in
4685 * print.h (scm_printer_apply): New prototype.

4698 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
4699 SCM_ASSERT: arg comes before pos.
4701 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4703 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied

4724 * ioext.c (scm_primitive_dup2): return the new file descriptor
4725 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
4727 (scm_fdopen): bug fix: don't try to make port unbuffered until its
4728 stream has been set.
4729 (scm_duplicate_port): deleted, there's now an implementation in

4744 * ports.h: prototypes too.
4745 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
4747 * fports.h: prototype too.
4748 * fports.c (scm_evict_ports): moved from ioext.c.
4750 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>

4755 * filesys.h: scm_close prototype.
4756 * filesys.c (scm_close): new procedure, can close file descriptors
4757 and ports (scsh compatible).
4759 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an

4782 data. (dynl_smob): Use it.
4783 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4784 the dynamic object data below the linking of the object to avoid
4785 memory leak when the linking code throws an error. Now the code
4786 leaks a whole dynamically linked library when must_malloc throws,
4787 but that should be much less likely.
4789 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4791 Changes to compile under gnu-win32, from Marcus Daniels:

4829 think this is left over from the (eq? '() #f) days.
4831 * read.c (recsexpr): Give this a dummy definition if
4832 DEBUG_EXTENSIONS isn't #defined.
4834 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
4836 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

4847 alloca.lo will be included in @LIBLOBJS@. Something better than
4848 this should be possible.
4849 * Makefile.in: Regenerated.
4851 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4853 * simpos.h: prototype for scm_primitive_exit.

4861 have to do this explicitly. Also, if regexp/basic is supplied, then
4862 turn off REG_EXTENDED.
4863 (scm_init_regex_posix): New regexp/basic symbol.
4864 (REG_BASIC): #define this if it is not already present.

4887 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4889 (scm_init_regex_posix): Define constants for the REG_mumble flags;

4911 (cwdr_outer_body): New function, to establish the user's handler,
4912 and pass control to cwdr_inner_body.

4923 across this. Only works on GCC. Otherwise, we hope for the best.
4924 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4925 the feeling that real thread systems will not need this...
4927 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4929 Try to detect when people are using one version of libguile and a

4941 primitive definitions under their Scheme names.
4943 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4944 1:2. Helps avoid confusion between installed and uninstalled libs.
4946 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4949 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4950 backslash from definition; this should be used like: GDB_INTERFACE;

4954 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
4955 new port unbuffered until its stream has been set.
4957 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4959 * ports.h: new prototype.

4969 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4971 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4972 argument plain char *.
4973 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
4975 * tag.c (scm_tag): Remove unreachable statement.
4976 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4977 top of the word, it should be unsigned.
4979 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4980 is defined, to avoid warnings; it's only used in the
4981 conflict-checking code. Which might go away anyway.
4982 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4983 conditionals; put the label definition in an #if too, to stifle
4986 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4987 ChangeLog-threads in the distribution.
4988 * Makefile.in: Regenerated.
4990 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4992 * guile-snarf.in: Changed regexp to support CPPs that insert
4993 whitespace between lexical tokens (which munges the `%%%' snarf
4996 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4998 * load.c (scm_init_load_path): Append $(datadir)/guile to
4999 %load-path, so modules do not have to be installed in Guile's
5000 current version directory.
5002 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
5004 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
5005 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
5006 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
5007 call the sysdep functions with deferred ints.
5008 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
5009 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
5010 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
5013 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
5016 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
5018 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
5020 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
5022 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
5025 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
5027 * eval.c (scm_lookupcar1): New procedure to cope with a race
5028 condition during lookup (when using threads).
5029 (scm_lookupcar): Implement in terms of scm_lookupcar1.
5030 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
5033 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
5035 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
5036 supplied. (Change from Tim Pierce.)
5038 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
5040 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
5041 23:47:01 1997" changelog: Slots are now initialized with `#f' by
5042 default and not `()'. `#f' is the canonical non-value in Scheme,
5045 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5047 * struct.c (struct_printer): New variable that holds a handle on
5048 the Scheme variable *struct-printer*. This variable can be set by
5049 Scheme code to override the printing of structures.
5050 (scm_print_struct): If struct_printer is set, call it. If it is
5051 not set, or returns #f, print the structure in the old fashion.
5052 Include "eval.h" for scm_apply.
5054 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
5056 * struct.c (scm_struct_ref, scm_struct_set_x): Use
5057 scm_struct_i_n_words to get the number of fields, not
5058 -scm_struct_n_extra_words.
5060 On the route to fancier struct printing:
5061 * struct.c (scm_print_struct): New function to print a structure.
5062 Include "genio.h" to support it. This function doesn't do
5063 anything interesting right now, but I think it should be here
5065 * struct.h: Include "print.h" and add prototype for
5067 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
5068 print structures ourself.
5070 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5072 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
5073 before applying the handler in case it doesn't return.
5075 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
5077 * scmsigs.h, async.h: updated.
5079 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
5082 * posix.c (scm_uname): interpret only negative values as an error.
5083 Solaris normally returns a positive value.
5085 * script.c (scm_compile_shell_switches): if we are not going into
5086 an interactive repl, set scm_mask_ints to zero so that asyncs can
5089 * simpos.c (scm_system): don't ignore/unignore signals around
5092 * posix.c (scm_open_pipe): don't ignore/unignore signals around
5095 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
5096 done in boot-9.scm instead.
5098 * scmsigs.c, async.c: Major rewriting of signal handling code.
5099 (scm_sigaction): new procedure.
5100 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
5102 (scm_raise): return unspecified, throw error on failure.
5104 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5106 * regex-posix.c (scm_init_regex_posix): Register the "regex"
5107 feature, to help boot-9.scm decide whether to import the regex
5110 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5112 * eval.c: Include scmconfig.h at the beginning of the file so that
5113 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
5116 * regex-posix.c: #include "_scm.h" before conditionally #including
5117 <regex.h>; the former defines HAVE_REGCOMP.
5119 * regex-posix.c: #include <regex.h> conditionally, so the file is
5120 CPP'able (for dependency scanning) even on systems that don't have
5123 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5125 Add new R4RS-compliant syntax for keywords.
5126 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5127 regardless of the setting of the `keywords' read option.
5128 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5129 can be re-read no matter what the setting of the `keywords' read
5132 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5134 Add support for POSIX regular expressions.
5136 * regex-posix.c, regex-posix.h: New files. (Some code
5137 is taken liberally from rx/rgx.c in the old Guile dist.)
5139 * init.c: Include regex-posix.h.
5140 (scm_boot_guile_1): Call scm_init_regex_posix.
5142 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5143 Add regex-posix.[ch] sources.
5144 * Makefile.in: Regenerated.
5146 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5147 to do this automatically? It didn't for me, bleh.)
5149 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5151 * fports.c (print_pipe_port): New function.
5152 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5153 latter doesn't even take the right arguments.
5155 * Makefile.am: Increment shared lib revision number. I think
5156 sometimes the uninstalled Guile finds the installed shared lib;
5157 Gord says doing this might help. As things turned out, I can't
5158 say whether it does.
5159 * Makefile.in: Regenerated.
5161 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5162 passing it as the closure argument to scm_boot_guile. (Bill
5165 * ports.c (print_void_port, putc_void_port, puts_void_port,
5166 write_void_port, flush_void_port, getc_void_port, close_void_port,
5167 noop0): Use ANSI prototypes instead of K&R declarations, so the
5168 initialization of void_port_ptob gets aggressively type-checked.
5169 Fix arguments of print_void_port and write_void_port. (Bill

5203 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5205 * script.c (scm_find_executable): Use prototype-style definition
5206 here; apparently it's not quite right to have const in a prototype
5207 and then use a K&R declaration. I wonder if stuff like this will
5208 go away if we compile with -Wrequire-prototypes, or whatever that
5209 is... (Bernard URBAN)
5211 * scmhob.h: New text from Bernard URBAN.
5213 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5215 * script.c: Don't #define const on hpux. Configure takes care of
5216 this. (Thanks to Larry Schwimmer.)
5218 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5219 decide whether to #include <unistd.h>, instead of listing a bunch
5220 of systems. Don't #include stdio twice. Removed dyked-out
5221 definition of scm_find_impl_file.
5223 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5225 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5226 library version info to 1:0.
5227 * Makefile.in: Regenerated.
5229 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

5233 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5234 throw.c: Update copyright years; these files have been worked on
5235 significantly in 1997, but only had copyright years for 1996.
5236 Also, change name of copyright holder on some from Mikael
5237 Djurfeldt to Free Software Foundation; he has signed papers
5238 assigning the changes to the FSF.
5240 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5241 reason not to give the user the option.
5243 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5244 Return #f on end-of-file when scanning table (i.e. when called
5245 with no arguments). Try to catch errors, when we can.
5246 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5248 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5249 external declarations. These are useful.
5251 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5253 * posix.c: don't include <sys/select.h> or define macros for
5254 select, since they were not used in this file.
5256 * filesys.c (scm_select): make the fifth parameter microseconds,
5257 not milliseconds. let the fourth parameter be either a real value
5258 or an integer or #f. The first, second and third arguments can
5259 now be vectors: the type of the corresponding return set will be
5261 (set_element, get_element): new static procedures.
5263 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5265 * strports.c (scm_eval_string): New function.
5266 (scm_eval_0str): Trivially re-implemented in terms of
5268 * strports.h (scm_eval_string): New extern decl.
5270 * net_db.c (h_errno): Add extern decl for this.
5272 * fports.c (local_pclose): New function.
5273 (scm_pipob): Use it in the initializer here.
5276 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5277 Use a meaningful error message when signalling an error. For
5278 this, scm_gethost must check h_errno rather than errno.
5280 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5282 * Makefile.in: Regenerated, using automake-1.1p.
5284 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5286 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5287 not SCM_UNSPECIFIED.
5289 * script.c (scm_compile_shell_switches): don't append (quit) if
5291 (scm_shell): call scm_exit_status and exit on the result of the
5294 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5296 Ensure that shared substrings are handled properly when passed to
5297 a system call or other foreign function. Many thanks to Tim
5299 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5300 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5301 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5302 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

5304 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5305 (scm_display_error_message): use RO macros when strings may be RO.
5306 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5307 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5308 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

5313 scm_strftime), vports.c (scm_make_soft_port): use
5314 SCM_COERCE_SUBSTR to make sure shared substrings are
5317 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5319 * error.c (scm_error): Add newline to error message.
5321 * init.c (scm_init_standard_ports): Doc fix.
5323 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5325 * dynl-shl.c: Completely replaced with new code from Bernard
5328 * script.c (scm_ice_9_already_loaded): New variable.
5329 (scm_compile_shell_switches): Use it.
5331 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5333 * filesys.c (scm_input_waiting_p): add missing third argument to
5336 * stime.c (scm_localtime): copy the result of localtime before
5337 calling gmtime in case they share a buffer.
5338 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5341 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5343 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5345 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5347 * Makefile.am (check-local): New target, which causes 'make check'
5348 to run gh_test_c and gh_test_repl, with some trivial input.
5349 * Makefile.in: Rgnrtd.
5351 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5353 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5356 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5358 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5359 sure how this was supposed to work.
5360 (scm_async_click): don't send SCM_TICK_SIGNAL.
5361 (scm_init_async): don't initialize %tick-thunk.
5363 * the following change doesn't affect the Scheme interface:
5364 gc-thunk is called at the end of garbage collection. however it's
5365 no longer implemented by pretending it's a signal.
5367 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5368 system async corresponding to scm_gc_thunk.
5369 * async.h: declare scm_gc_async.
5370 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5371 gc-thunk directly, instead of going through a signal handler.
5372 (scm_gc_async): new variable, points to the GC system-async.
5373 (scm_init_async): save the GC async as scm_gc_async instead
5374 of using system_signal_asyncs.
5375 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5377 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
5379 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
5380 Don't screw up if we're interrupted.
5381 * Makefile.in: Regeneradet.
5383 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5385 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5387 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5388 we're not using AM_INIT_GUILE_MODULE any more.
5389 * Makefile.in: Reneregated.
5391 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5393 Functions for finding variable bindings, grace à Tim Pierce.
5394 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5395 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5397 Get 'make dist' to work again.
5398 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5399 * Makefile.in: Regenerated, like a surry without a fringe on top.
5401 Changes for reduced Guile distribution: one configure script,
5403 * configure.in, configure: Removed.
5404 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5405 real configure script lives.
5406 * Makefile.in, scmconfig.h.in: Regenerated.
5408 * init.c: #include "script.h", to get prototype for script.c's
5411 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5413 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5414 scm_must_malloc, not raw malloc.
5416 * script.c (scm_compile_shell_switches): Dyke out debugging output
5419 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5421 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5423 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5424 system has them. Hope this is safe. Previously
5425 sys/timeb.h was included if HAVE_FTIME was defined or if
5426 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5427 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5429 * ioext.c (scm_setfileno): add missing third argument to
5430 scm_misc_error call.
5432 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5434 * eq.c (scm_equal_p): Correctly compare strings of different
5435 varieties. (Thanks to Tim Pierce.)
5437 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5439 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5440 #! block comment must occur on a line all by itself.
5442 Move most of the guts of shell command processing into libguile,
5443 so guile.c can be very small (and eventuallly auto-generated. (I
5444 mean, generated mechanically, not self-generated. Hmm.))
5445 * guile.c, script.c, script.h: New source files.
5446 * init.c (scm_boot_guile_1): Call scm_init_script.
5447 * libguile.h: #include "script.h".
5448 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5449 targets, for new executable.
5450 (libguile_la_SOURCES): Mention script.c.
5451 (modinclude_HEADERS): Add script.h.
5452 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5453 not dynamic linking is enabled. This is because we're generating
5454 executables now. Move CY_AC_WITH_THREADS call after those, so the
5455 values of cy_cv_threads_libs captures the libs chosen above.
5456 * Makefile.in, configure, aclocal.m4: Regenerated.
5458 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5459 We don't maintain this interface any more, and it just confuses
5462 * alloca.c: #include <scmconfig.h>, not <config.h>.
5463 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5464 it'll get included in disties.
5466 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5468 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5469 be distributed, because they confuse people.
5470 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5472 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>

5475 OpenBSD by default).
5476 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5477 * configure, scmconfig.h.in: Regenerated.
5479 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5481 * backtrace.c (scm_backtrace): Split message string across
5482 newlines properly. GCC is more tolerant of this than other
5485 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5487 Merge threads directory into libguile.
5488 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5489 threads.h: New source files.
5490 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
5491 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5493 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5494 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5495 coop-threads.c.cygnus, coop-threads.h.cygnus.
5496 * configure.in: If we're using threads, include threads.o in
5498 * _scm.h, libguile.h: threads.h lives in this directory now.
5499 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5500 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5501 currently used, but brought along for information's sake.
5502 * ChangeLog-threads: log from old 'threads' directory.
5503 * Makefile.in, configure: Rebuilt.
5505 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5507 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5510 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5512 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5514 Merge GH interface library into libguile.
5515 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5516 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5517 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5518 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5520 (EXTRA_libguile_la_SOURCES): ... here.
5521 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5522 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5523 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5524 New variables, describing how to build the gh test programs.
5525 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5526 build the test programs, and we probably should have been linking
5527 libguile.la against them all along, to support AIX shared libs.
5528 Add cflags for threads to CFLAGS; add libs for threads to new
5529 variable THREAD_LIBS, used in Makefile.am.
5530 * ChangeLog-gh: log from old `gh' subdirectory.
5531 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5533 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5535 * acconfig.h: Undo change of Apr 9; including the definition of
5536 PACKAGE in the guile headers conflicts with applications' own
5538 * scmconfig.h.in: Regenerated.
5540 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

5547 when PROC is receiving no arguments.
5549 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5551 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5552 have S_IFSOCK. This is the case under Ultrix.
5554 * posix.c (scm_status_exit_val, scm_status_exit_val,
5555 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5556 Ultrix versions of WIFSTOPPED, etc., which assume that their
5557 arguments are lvalues (hmm).
5559 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5561 * eval.c: Doc fixes.
5563 * throw.c: Doc fixes; rearranged.
5565 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5567 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5569 * acconfig.h: Added entry for PACKAGE.
5570 * scmconfig.h.in: Regenerated.
5572 Changes to work with automake-1.1n, which has better libtool support.
5573 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5574 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5576 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5578 * Makefile.in: Rebuild.
5580 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5582 * stime.c (scm_mktime): take an optional zone argument.
5583 (scm_localtime): check putenv return value.
5584 (scm_strftime, scm_strptime): moved from posix.c. move #include
5586 stime.h, posix.h: update prototypes.
5587 (bdtime2c, setzone, restorezone): new static procedures.
5588 (scm_mktime, scm_strftime): use them.
5589 (scm_strftime): don't call mktime before strftime. Use
5590 filltime for return value.
5591 (filltime): convert NULL zname to #f.
5592 (scm_strptime): return a count of characters consumed, not
5593 the remaining string.
5595 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5597 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
5598 (scm_mktime): likewise.
5600 Uncomment localtime and mktime.
5602 * configure.in: add AC_STRUCT_TIMEZONE.
5604 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5606 * stime.c (scm_init_stime): don't define ticks/sec.
5607 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5608 return value problem and is still portable.)
5610 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5612 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5613 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5614 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5615 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5616 cpp_err_symbols.c): Corresponding changes.
5617 * Makefile.in: Regenerated.
5619 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5621 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5622 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5623 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5624 * putenv.c: new file, from sh-utils 1.12.
5626 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5627 since allocation isn't for Scheme objects.
5628 (scm_putenv): copy strings before placing in the environment.
5630 * stime.c (scm_current_time): throw an error if time returns -1,
5631 instead of returning #f.
5632 (scm_get_internal_real_time, scm_get_internal_real_time): use
5633 scm_long2num for return value instead of SCM_MAKINUM.
5635 * stime.h: prototypes updated.
5637 * stime.c (scm_time_in_msec): apparently unused, deleted.
5639 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5641 * configure.in: check for gettimeofday.
5643 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5644 which may be more usefully portable than a gettimeofday interface.
5646 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5648 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5650 * Makefile.in: Regenerated.
5652 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5654 * stime.c (filltime): recovered static procedure.
5655 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5658 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5659 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5661 * posix.c (scm_mknod): split the mode argument into type and perms
5662 arguments, like the extra fields returned by stat.
5664 * fports.c (scm_pipob): set the close, free and print procedures.
5665 (scm_close_pipe): new procedure.
5667 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5668 define them in boot-9.scm
5670 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5672 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5673 wan't defined. Don't include fd.h.
5675 * Previously fd.h was regenerated whenever configure was run,
5676 forcing a couple of files to be recompiled.
5678 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5679 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5680 Check for _fileno as well as _file.
5682 * ioext.c: don't fd.h.
5683 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5686 * Change the stratigy for getting information about errno
5687 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5688 generating lists of symbols during the build process, which will
5689 not always work, include comprehensive lists in the distribution.
5690 To help keep the lists up to date, the "check_signals" and
5691 "check_errnos" make targets can be used.
5693 * configure.in: don't check for a command to extract errno codes.
5694 * Makefile.am: update file lists, remove errnos.list and errnos.c
5695 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5696 check_errnos targets.
5697 (CLEANFILES): remove errnos.c and errnos.list, add
5698 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5699 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5700 * errnos.default: deleted.
5701 * cpp_signal.c: new file.
5702 * cpp_errno.c: renamed from errnos_get.c.
5703 * cpp_err_symbols, cpp_sig_symbols: new files.
5704 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5705 * error.c (scm_init_error): #include cpp_err_symbols instead of
5707 * posix.c (scm_init_posix): don't intern signal symbols. #include
5710 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5712 * strop.c (scm_i_index): allow the lower bound to be equal to the
5713 length of the string, so a null string doesn't always give an error.
5715 * posix.h: new prototypes.
5716 * posix.c (scm_status_exit_val, scm_status_term_sig,
5717 scm_status_stop_sig): new functions, as in scsh. They break down
5718 process status values as returned by waitpid.
5720 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5722 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5723 configure doesn't know about it.
5725 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5727 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5729 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5730 which defines C variables with global linkage.
5732 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5734 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5737 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5739 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5740 has time to check why this doesn't work well with continuations.
5742 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5744 * Fix shell syntax error; some shells won't tolerate
5745 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5747 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5749 * posix.c (scm_uname): throw an error if uname fails instead
5752 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5754 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5757 * async.c (scm_ints_disabled): definition moved from error.c.
5759 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5761 * acconfig.h: Removed PACKAGE.
5763 * scmconfig.h.in: Regenerated.
5765 * snarf.h: g++ says it's non-portable not to specify the first
5766 argument in a varargs declaration. I introduced the first
5767 argument by using preprocessor conditionals.
5769 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5771 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5772 (scm_freopen): use RO string macros for filename and modes.
5773 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5775 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5776 (scm_mknod): use RO string macros for path.
5778 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5779 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5781 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5782 use SCM_ROSTRINGP and SCM_ROCHARS.
5784 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5786 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5789 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5790 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5791 support for byte vectors.
5793 * print.c (scm_iprin1): Limit number of vector elements printed
5794 according to pstate->length.
5796 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5798 * backtrace.c (scm_display_error_message): don't segv if message
5801 * error.h: prototype for scm_error_scm.
5803 * error.c (scm_error_scm): new procedure, reimplements scm-error
5804 in C and uses scm_error.
5806 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5808 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5809 pointer to the Scheme variable read-hash-procedures and intern it
5810 in scm_init_read. Modify scm_read_hash_extend and
5811 scm_get_hash_procedure to use the pointer.
5813 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5815 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5816 (SCM_KEYWORD_STYLE): defined.
5818 * read.c (scm_read_opts): add a keywords option. This isn't a
5819 boolean option, in case someone wants to add support for DSSSL
5821 Setup scm_keyword_prefix symbol.
5822 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5824 I've left keyword support disabled by default, since it doesn't
5825 seem to break the module system and it gives R4RS standard behaviour.
5826 It can be reactivated with (read-set! keywords 'prefix).
5828 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5830 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5831 before constructing arbiter.
5833 * eval.c (scm_m_define): Bugfix: Check that the object is a
5834 closure before setting the procedure property!
5836 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5838 * ports.c: Removed `ungetc-char-ready?'.
5840 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5842 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5843 (idea from Mikael: make it a pair so scm_permanent object only
5845 (scm_read_hash_extend): don't call scm_permanent_object.
5846 (ideas from Mikael): if chr is already in the list, replace its
5847 procedure instead of appending it again. If proc is #f, remove
5849 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5851 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5853 * gdbint.c (gdb_read): update scm_lreadr usage.
5855 * load.h: update prototypes.
5857 * load.c (scm_primitive_load, scm_read_and_eval_x,
5858 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5860 * read.h: add prototype for scm_read_hash_extend. Change args for
5863 * read.c (scm_read_hash_procedures): new variable.
5864 (scm_read_hash_extend): new procedure.
5865 (scm_get_hash_procedure): new procedure.
5866 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5867 for extended # processing.
5868 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5869 scm_read_token): remove case_i, sharp arguments. Change callers.
5871 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5873 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5874 (SCM_CASE_INSENSITIVE_P): define.
5876 * read.c: add case-insensitive option to scm_read_opts.
5877 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5878 to determine whether to convert symbol case.
5879 (default_case_i): definition removed.
5880 * read.c (scm_read_token): if case_i, downcase ic before doing
5883 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5885 * configure.in: Added configuration option `guile-debug'.
5886 Configure with --enable-guile-debug if you want a bunch of extra
5887 functions used for debugging when developing Guile.
5889 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5891 * procs.c (make-cclo): New undocumented debugging procedure: Make
5892 compiled closure with internal procedure PROC and length LENGTH.
5893 Only compiled if GUILE_DEBUG is defined.
5895 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5897 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5899 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5901 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5902 with 3 or more args internally to the evaluator.
5904 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5906 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5907 with 3 or more args internally to the evaluator. This is mainly
5908 because we don't want to pass entry and exit points of the
5909 debug support twice, but it also seems to increase the speed of
5910 the evaluator for such calls (e. g. (+ 1 2 3)).
5912 * backtrace.c (scm_display_application): New procedure:
5913 display-application; Set fancy printing parameters individually
5914 for different types of display (backtrace, error, application).
5915 (These should of course be customizable!)
5917 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5918 clear the CHECK-flags.
5920 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5922 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5924 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5926 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5927 from pairs with a GLOC in the car.
5929 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5930 otherwise `symbol-hash' will behave badly.
5931 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5932 we get segmentation fault!
5934 * symbols.c: Added #include "weaks.h". New functions:
5935 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5936 moved to an extraneous library when we split libguile.)
5938 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5940 * filesys.c (scm_stat): stat now takes fport arguments too as
5941 documented in the manual.
5943 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5945 * debug.c (scm_single_step): Bugfix: Call continuation with
5946 scm_call_continuation instead of throwing to it.
5948 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5950 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5951 argument wasn't declared to be optional.
5953 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5955 * stime.c (scm_init_stime): Add feature "current-time".
5957 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5959 * throw.h: prototype for scm_exit_status.
5960 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5961 args to derive an exit status. Allows (quit) to work from a
5963 (scm_exit_status): new function.
5966 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5968 * eval.c (scm_deval): Removed some old code.
5969 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5971 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5974 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5977 * procs.c: Introduce the existent C function scm_thunk_p at the
5978 Scheme level as well.
5980 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5982 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5983 used from C to easily lookup the value of a symbol in the current
5986 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5988 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5989 scm_init_unif in this file. This will also fix a previous problem
5992 * configure.in: Added AM_MAINTAINER_MODE
5994 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5996 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5999 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6001 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
6002 source files that are not always included in libguile but should
6003 have their dependencies calculated by automake. This variable is
6004 recognized by automake, no further magic is needed.
6005 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
6006 to deal exclusively with *.lo files, as it seems. The *.o files
6007 are built automatically when the corresponding *.lo file gets
6010 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
6012 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
6015 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
6017 * unif.c (scm_array_set_x): minor change to argument error checking.
6019 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
6021 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
6022 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
6023 They should only be included in the library at configure.in's
6025 (libguile_la_LDADD): Include the appropriate .lo files here.
6026 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
6027 so we know when to build them (and their .lo bretheren).
6028 * configure.in (LIBLOBJS): New substituted variable. We let
6029 configure decide which .o files to include in LIBOBJS, and then
6030 put the corresponding list of .lo files in LIBLOBJS. The latter
6031 is what we pass to libtool.
6032 * Makefile.in, configure: regenerated.
6034 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
6036 * symbols.c (scm_sysintern0): New function. Contains the core of
6037 old scm_sysintern but doesn't take a second value argument.
6038 (scm_sysintern): Now uses scm_sysintern0.
6039 (scm_sysintern_no_module_lookup): Renamed to
6040 scm_sysintern0_no_module_lookup and doesn't take a second value
6041 argument any longer.
6043 * symbols.h (scm_sysintern0: Added declaration.
6045 * options.c (scm_init_opts): Use scm_sysintern0 instead of
6046 scm_sysintern when interning option keys. Otherwise we risk
6047 destroying the values of already interned variables.
6049 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
6050 scheme-level boolean (use SCM_NFALSEP).
6052 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
6054 (scm_backtrace): New function. (C version of old function from
6055 boot-9.scm) Motivation: Make it possible to display backtraces
6056 without depending on boot-9.scm. (I'm uncertain if this
6057 motivation is good enough...)
6059 * root.h (scm_root_state): Add member the_last_stack_var.
6060 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
6062 * root.c (mark_root): Mark scm_the_last_stack_var.
6064 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
6067 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
6069 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
6070 1. mark_lazy_catch didn't mark the smob.
6071 2. Both functions above have standard variants:
6072 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
6073 free_lazy_catch --> scm_free0.
6075 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
6077 * throw.c (scm_internal_lazy_catch): New function.
6078 (scm_lazy_catch): Rewritten to use it.
6079 (scm_ithrow): Handle the new lazy catch representation.
6080 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
6081 that doesn't have a jmpbuf is a lazy catch clause.
6082 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
6083 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
6084 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
6086 (scm_init_throw): Register the new lazy-catch smob type.
6087 * throw.h (scm_internal_lazy_catch): decl for new function.
6089 * throw.c (scm_internal_catch): Doc fixes.
6091 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
6092 configure.in. Including this might cause problems if applications
6093 that link against libguile include their own copies of alloca, but
6094 if they're using autoconf, they should be adding libguile to LIBS
6095 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
6096 the copy in libguile, and things will be okay. (I think.)
6098 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6100 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
6102 strop.h: move prototypes too.
6104 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6106 * posix.c (scm_init_posix): don't intern EINTR since it's now done
6109 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
6110 etc. I deleted them from filesys.c long ago, but didn't
6111 notice they were here too (although ineffective since
6112 sys/stat.h wasn't included).
6114 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
6116 * eval.c: Don't define alloca in GCC case. gcc will automatically
6117 use __builtin_alloca if appropriate.
6119 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6121 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6122 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6123 that values of automatic variables are preserved. See comments
6124 for safe_setjmp for details.
6126 Change from Thomas Morgan:
6127 * variable.c: Include eq.h.
6128 (var_equal): New function.
6129 (variable_smob): Use var_equal as the discriminator for variables.
6131 * throw.c (s_throw): Remove extraneous declaration.
6133 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6134 * eval.c: Add necessary CPP cruft to support that.
6135 * configure, Makefile.in, scmconfig.h.in: regenerated.
6137 Change from Thomas Morgan:
6138 * procprop.c (scm_procedure_properties): Convert the Scheme
6139 boolean returned by scm_procedure_p into a C boolean before using
6140 it as a condition for SCM_ASSERT.
6141 (scm_procedure_property): Likewise.
6143 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6144 indications of Unixness.
6147 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6149 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6151 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6153 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6154 "unknown # object" error messages.
6156 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6157 (scm_i_index) and declare it static. Add a 'direction' argument
6158 to indicate what way the search should go.
6159 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6161 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6162 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6164 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6166 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6168 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6169 to avoid clash with various scsh forks.
6171 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6173 The following two changes (ramap.c, throw.c) are motivated by the
6174 apparent unportability of forward declarations of static arrays of
6175 the form `static foo bar[];'.
6177 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6178 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6180 * throw.c (scm_throw): Moved above scm_ithrow.
6182 * options.h: Removed the extern declarations of scm_yes_sym and
6183 scm_no_sym since these are static.
6185 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6187 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6189 * Makefile.am: remove AWK=@AWK@.
6190 Add a rule for generating errnos.list.
6191 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6193 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6194 don't extract errnos, just set a variable (avoids the
6195 need to recompile error.c just because configure is run.)
6197 * unif.h: update prototypes.
6198 * unif.c (scm_uniform_array_read,write): change the offset and
6199 length arguments to start and end, for consistency.
6201 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6203 * ioext.h: update prototypes.
6204 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6205 scm_read_line_x, it's a more general procedure using an
6206 interface from scsh. read-line and read-line! are now defined
6208 Note that the new read-line trims the terminator
6209 by default, previously it was appended to the returned string. An
6210 optional argument specifies how to process the terminator (scsh
6211 compatible). For the old behaviour: (read-line port 'concat).
6212 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6213 returns a pair, but is converted to multiple values if the scsh
6216 socket.h: update prototypes.
6217 * socket.c (scm_recvfrom): for consistency with other procedures,
6218 take start and end as separate optional arguments.
6219 (scm_recv, scm_recvfrom): don't allow the second argument
6220 to be a size, only a buffer. Change the scheme names to
6221 recv! and recvfrom!. Don't return the buffer.
6223 * ioext.h, posix.h: move prototypes too.
6224 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6225 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6226 "read.h" and "unif.h".
6227 * ioext.c: include "chars.h"
6229 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6231 * dynl.c: The dynamic linking and module registration functions
6232 are now defined even when dynamic linking is not available for the
6233 host system. Some of their functionality can be done without
6234 dynamic linking; when it's really needed, they throw errors.
6236 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6238 * configure.in: Only define DYNAMIC_LINKING when one of the system
6239 dependent functions is detected.
6240 * dynl.c (scm_dynamic_func): New function to get the address of a
6241 function in a dynamic object.
6242 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6243 produced by scm_dynamic_func as the thing to call.
6245 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6247 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6248 (scm_register_module_xxx, scm_registered_modules,
6249 scm_clear_registered_modules): New functions.
6251 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6253 * symbols.c (scm_sysintern): Renamed to
6254 scm_sysintern_no_module_lookup.
6255 (scm_sysintern): New function to take the place of the old
6256 scm_sysintern. It uses the current toplevel lookup closure to give
6257 the symbol its value. This is a temporary hack to put packages
6258 like gtcltk into their own module.
6259 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6260 us whether `scm_top_level_lookup_closure_var' has been initialized
6262 * eval.c (scm_init_eval): Set it.
6264 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6266 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6267 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6269 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6271 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6272 scm_sys_dup): deleted: FD capability will be added to other
6274 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6275 scm_fd_free, fd_smob, scm_intern_fd.
6276 (scm_open): renamed from scm_sys_open. Return a port instead of
6277 an FD object. Make the mode argument optional.
6278 (scm_sys_create): deleted, it's just a special case of open.
6279 (scm_init_filesys): move interning of constants O_CREAT etc.,
6280 here (were previously using SCM_CONST_LONG macro).
6281 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6283 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6284 include "fports.h" and <stdio.h>
6285 (scm_stat, scm_select): don't support FD objects.
6287 * error.h: adjust scm_syserror_msg prototype.
6288 * error.c (scm_syserror_msg): take an extra argument for errno.
6289 Using the global value didn't always work, since it could be
6290 reset by procedure calls in the message or args arguments.
6292 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6293 I don't understand why the check was there (and what about the
6296 * strop.c (scm_string_copy): allow shared substrings to be copied.
6298 * unif.h: corresponding change to prototypes.
6299 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6300 recognize two new optional arguments: offset and length. Allow
6301 the port argument to be an integer (file descriptor, for scsh).
6302 Include <unistd.h> for "read" prototype.
6304 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6306 * socket.c: don't include filesys.h.
6308 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6310 * Makefile.am: add AWK=@AWK@ (?)
6312 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6314 Add a rule to generate errnos.c from errnos.
6315 * error.c (scm_init_error): include errnos.c.
6316 * errnos_cnvt.awk: new file, converts the list of errno codes to
6318 * errnos_get.c: new file.
6319 * errnos.default: new file, contains errnos to try if they can't
6320 be extracted from errno.h.
6321 * configure.in: if using GCC, try and extract errno codes from
6325 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6327 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6328 * Makefile.am: Made libguile into a libtool library.
6329 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6330 Set libtool_libs to indicate that libguile is a libtool library.
6331 See guile/ChangeLog for details.
6332 * .cvsignore: ignore "*.lo", the libtool library objects.
6334 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6336 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6337 use htons in getservbyport argument.
6339 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6341 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6342 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6345 * objprop.c (scm_object_property): No need to take the CDR of the
6346 value returned by scm_object_properties, since Aug 20 change.
6348 * configure.in: When checking for struct linger, #include
6349 <sys/types.h> as well as <sys/socket.h>. I've never known
6350 <sys/types.h> to cause any portability problems, and Solaris's
6351 <sys/socket.h> needs it.
6352 * configure: Rebuilt.
6354 I think the Sun compiler has chosen a perverse way to interpret
6355 ANSI declarations combined with K&R definitions. We'll
6356 appease it a little bit. But when it invades France, we fight.
6357 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6358 * print.h (scm_iprlist): Here too.
6359 * numbers.c (scm_divbigdig): Change definition to match
6360 declaration in numbers.h.
6361 * unif.c (scm_makflo): Change definition to match declaration in
6364 * init.c (scm_boot_guile): Don't return the value of
6365 scm_boot_guile_1. This function doesn't return a value;
6366 scm_boot_guile_1 doesn't return a value (or return at all).
6368 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6371 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6372 compile. I have a feeling this function is a bad idea anyway ---
6373 one should always test for features, not systems.
6375 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6376 semicolons. Only pure luck kept this from being noticed earlier.
6378 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6380 * socket.c (scm_recvfrom): Added missing semicolon.
6382 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6384 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6385 the buffer and start and end positions for scsh networking
6388 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6390 * configure.in: Revert previous change to this file; the problem
6391 is due to transient automake weirdness.
6392 * configure: Rebuilt.
6394 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6395 PLUGIN/guile.libs. configure generates the latter from the former.
6396 * Makefile.in: Rebuilt.
6398 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6399 need this if we install scripts, like guile-snarf.
6400 * configure: Rebuilt.
6402 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6404 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6406 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6408 * socket.c (scm_addr_vector): fix faulty scm_listify.
6410 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6412 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6413 style block comment is no longer considered an error.
6415 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6417 * PLUGIN/guile.libs.in: New file.
6418 * PLUGIN/guile.libs: Removed from repository.
6419 * configure.in: Create PLUGIN/guile.libs from
6420 PLUGIN/guile.libs.in. This is for including additonal libraries
6421 needed for dynamic linking.
6422 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6423 instead of PLUGIN/guile.libs.
6425 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6427 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6429 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6430 occurrences of the given element from the list, not just the
6431 first. This is how the Emacs Lisp functions behave, how the
6432 analogous Common Lisp functions behave, and (I believe) how the
6433 older Maclisp functions worked. I realize that this change may
6434 break code, but it seemed better to break it before the Guile
6437 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6438 Their prototypes were already present in gc.h, but they weren't
6440 (scm_init_storage): Initialize scm_protects.
6441 * root.c (scm_protects): New element of scm_sys_protects.
6443 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6445 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6447 * libguile.h: Added #include "libguile/net_db.h".
6449 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6450 30 change. That file is only meant for communication between the
6451 configuration process and load.c. If code linked against libguile
6452 wants to get at the paths mentioned in libpath.h, it can call
6453 functions declared in load.h.
6455 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6457 * libguile.h: Removed #include "libguile/fdsocket.h"
6459 * net_db.c: Added #include <sys/socket.h>.
6461 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6463 * filesys.c (scm_input_waiting_p): use select in preference to
6464 FIONREAD, since the latter doesn't detect EOF.
6465 Throw error if neither select nor FIONREAD available.
6467 * socket.c (scm_connect): take a port, not a fd object.
6468 (scm_fill_sockaddr): throw an error if fam is not recognised.
6469 (scm_bind): use scm_fill_sockaddr.
6470 (scm_listen): take a port, not a fd object.
6471 (scm_accept): take and return a port. return #f in the car if
6472 address can't be got
6473 (scm_sock_fd_to_port): new procedure.
6474 (scm_socket): use scm_sock_fd_to_port.
6475 (scm_addr_vector): throw error if unrecognised address type.
6476 take an extra argument with the calling procedure name.
6477 (scm_getsockname): take a port. return #f if address can't be got.
6478 (scm_getpeername): take a port. return #f if address can't be got.
6479 (scm_recvfrom): take a port. return #f for address component if can't
6481 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6482 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6484 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6486 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6487 use separate data pointers, to allow them to be designed
6488 independently and reused.
6489 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6490 Renamed from catch_body, catch_handler, and uncaught_throw; made
6492 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6494 (scm_catch): Use the above.
6495 (scm_throw): Don't bother printing a message for an uncaught
6496 throw; we establish a default handler in init.
6497 * throw.h (scm_internal_catch): Prototype updated.
6498 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6500 (struct scm_body_thunk_data): New structure, used as data
6501 argument to scm_body_thunk.
6502 * init.c (struct main_func_closure): New structure, packaging up
6503 the data to pass to the user's main function.
6504 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6505 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6506 scm_internal_catch to establish a catch-all handler, using
6507 scm_handle_by_message. This replaces the special-case code in
6509 (invoke_main_func): Body function for scm_internal_catch; invoke
6510 the user's main function, using the main_func_closure pointer to
6511 decide what to pass it.
6512 * root.c (struct cwdr_body_data): Remove handler_proc member.
6513 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6514 (cwdr_handler): Removed.
6516 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6518 * socket.h (SCM_P): update bind prototype.
6519 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6520 include "feature.h".
6521 (scm_socket): return a port, not a file descriptor object.
6522 include "fports.h" and <unistd.h>
6523 (scm_bind): take a port, not a file descriptor object.
6524 take an extra argument for address args.
6526 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6527 INADDR_NONE, INADDR_LOOPBACK.
6529 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6531 * init.c: include net_db.h and not fdsocket.h.
6532 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6534 * Makefile.am: corresponding changes.
6535 * socket.h: renamed from fdsocket.h, fix names.
6536 * net_db.h: renamed from socket.h, fix names.
6537 * socket.c: renamed from fdsocket.c.
6538 remove _sys from procedure names.
6539 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6540 add "socket" to features list.
6541 * net_db.c: renamed from socket.c.
6542 remove _sys from procedure names.
6543 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6544 add "net-db" to features list.
6545 include "net_db.h". don't include <sys/socket.h> or
6548 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6550 * tags.h (scm_tags): Removed comma at end of last enumerator.
6552 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6554 Don't use GCC extensions to allocate space for debugging frames.
6555 (Here he goes again! Why do we put up with this?!)
6556 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6557 an scm_debug_info structure, not an in-line array of them. Add
6558 'info' member, to say how many vect elements we've used, for eval
6560 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6561 a new variable debug_info_end to mark the end of vect, instead of
6562 the address of the 'info' pointer itself.
6563 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6564 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6565 (SCM_APPLY): Explicitly allocate space for debug.vect.
6566 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6567 * stacks.c: Adjusted for new debug frame structure.
6568 (RELOC_INFO, RELOC_FRAME): New macros.
6569 (stack_depth, read_frames): Use them, and new scm_debug_frame
6570 element 'info', instead of magically knowing that eval frames have
6571 an info pointer sitting after vect.
6572 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6574 (scm_init_stacks): Formatting tweaks.
6576 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6578 Give GCC more control flow information, so it can be sure that
6579 variables aren't used uninitialized.
6580 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6581 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6582 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6583 scm_misc_error): Tell GCC that these functions never return.
6584 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6585 out the field type, call abort if SCM_ASSERT returns, to placate
6587 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6588 scm_wta ever returns. We can't handle this case anyway, and this
6589 gives the optimizer more information.
6590 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6591 scm_wta ever returns.
6593 In some cases, the code is fine, but GCC isn't smart enough to
6594 figure that out; this usually happens when one variable is only
6595 initialized and used when a particular condition holds true, and
6596 we know that condition will never change within a given invocation
6597 of the function. In this case, we simply initialize the variables
6598 to placate the compiler, hopefully to a value which will cause a
6599 crash if it is ever actually used.
6600 * print.c (scm_iprin1): Initialize mw_pos.
6601 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6602 * throw.c (scm_ithrow): Initialize dynpair.
6603 * unif.c (scm_uniform_vector_ref): Initialize cra.
6604 * struct.c (init_struct): Initialize prot.
6605 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6607 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6608 if EXPR contains no expressions.
6610 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6612 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6613 cause an infinite loop (???). So much for the algebraic
6614 equivalency of variable-sized arrays and alloca...
6616 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6618 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6619 a SCM boolean, not a C boolean.
6621 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6623 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6624 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6625 rules for raising scm_mtrigger. Previously, unfortunate but not
6626 unlikely circumstances could result in almost constant invokation
6627 of the gc. Now, this situations should be less likely, but they
6628 are not prevented completely.
6630 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6632 * numbers.c (scm_fuck): Procedure removed; looks like old test
6634 * numbers.h: Prototype removed.
6636 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6638 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6639 array to a pointer, to match my Nov 21 change in eval.c.
6641 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6643 * libguile.h: Added #include "libguile/backtrace.h", #include
6644 "libguile/stacks.h".
6646 * strings.c (scm_string scm_make_string scm_string_ref
6647 scm_string_set_x scm_string_equal_p scm_string_append):
6648 Bugfix according to scm patch from Aubrey Jaffer:
6649 Corrected long-standing
6650 (not (eqv? (integer->char 128)
6651 (string-ref (make-string 1 (integer->char 128)) 0)))
6652 bug found by John Kozak <jk@noontide.demon.co.uk>.
6654 * strports.c, strports.h: Make scm_eval_0str return the value of
6655 the last expression evaluated (previously, it returned void).
6657 * strports.c, strports.h: New function: scm_read_0str. Does what
6660 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6662 * simpos.c (scm_getenv): return #f if string can't be found in the
6663 environment instead of throwing an exception, for compatibility
6664 with numerous other systems.
6666 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6668 * Makefile.am (.c.x): Use guile-snarf.
6669 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6671 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6673 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6675 * backtrace.c (scm_display_error_message): Made non-static, and
6676 renamed from display_error_message.
6677 * backtrace.h (scm_display_error_message): Added extern decl.
6678 * throw.c (uncaught_throw): Use it to display the error message.
6680 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6682 * inet_aton.c: Use #if 0, not #ifdef 0.
6684 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6686 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6687 to convert the returned value.
6688 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6689 the offset argument.
6691 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6693 Add new interface to catch/throw, usable from C as well as
6695 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6696 (scm_internal_catch): New function, replaces...
6697 (scm_catch_apply): Deleted.
6698 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6699 mechanism which is a bit more code, but can be used nicely from C
6700 and implement the Scheme semantics as well.
6701 (scm_internal_catch): This is the replacement; it's named after
6702 the analogous function in Emacs.
6703 (scm_catch): Reimplemented in terms of the above.
6704 (struct catch_body_data, catch_body, catch_handler): New
6705 functions, used by scm_catch.
6706 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6707 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6708 support for new cwdr.
6710 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6713 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6715 * acconfig.h: Added DYNAMIC_LINKING symbol.
6716 * configure.in: Add option and checks for dynamic linking.
6717 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6718 dynl.h: New files for dynamic linking support.
6719 * Makefile.am (libguile_a_SOURCES):
6721 (modinclude_HEADERS): Added "dynl.h".
6722 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6724 * init.c (scm_boot_guile_1): Call
6725 scm_init_dynamic_linking to initialize dynamic linking support.
6727 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6729 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6730 (as we Schemers say). It needs to be global, so that I can tweak
6731 it for the proper operation of unexec.
6732 (scm_boot_guile_1_live): New variable, see above.
6734 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6736 * guile-snarf.sh: Removed.
6737 * PLUGIN/guile.libs: Added dependency for -lm.
6738 * acinclude.m4: Renamed from aclocal.m4.
6739 * PLUGIN/greet: Removed.
6740 * Makefile.am, aclocal.m4: New files.
6741 * configure.in: Updated for Automake.
6743 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6745 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6746 and not top_level_lookup_thunk_var.
6748 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6750 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6752 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6754 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6755 Scheme function, instead of syntax. Single argument is now a
6758 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6760 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6761 scm_ra_divide): Properly terminate statements passed as arguments
6762 to IVDEP macros. (Thanks to Bernard Urban.)
6764 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6765 with non-constant sizes. (Thanks to Bernard Urban.)
6767 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6769 It's an "eval closure", not an "eval thunk." A thunk is a
6770 function of no arguments.
6771 * root.h (struct scm_root_state): Renamed
6772 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6773 (scm_top_level_lookup_closure_var): Renamed from
6774 scm_top_level_lookup_thunk_var.
6775 * root.c (mark_root): Uses changed.
6776 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6777 * init.c (scm_start_stack): Uses changed.
6778 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6779 Change scheme-visible name to *top-level-lookup-closure* from
6780 *top-level-lookup-thunk*.
6782 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6784 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6785 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6787 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6789 * gc.c (struct scm_heap_seg_data): Doc fixes.
6791 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6792 sweeping. Then, prepend each segment's free cells to its
6793 freelist, rather than wiping out the old value. (Thanks to Marius
6796 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6797 scm_check_freelist, scm_debug_newcell): New functions and
6798 variables, for debugging freelist problems.
6799 * pairs.h (SCM_NEWCELL): New debugging version added.
6800 * gc.h (scm_debug_newcell): Added extern declaration, used by
6801 debugging version of SCM_NEWCELL.
6803 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6805 On some systems <libc.h> conflicts with <unistd.h>, and should not
6806 be #included at all.
6807 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6808 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6809 * configure.in: Call it.
6810 * posix.c, filesys.c: Use its results to decide whether or not to
6812 * configure, scmconfig.h.in: Rebuilt with autoconf and
6815 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6817 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6818 pointer to the stdio stream before calling scm_setbuf0, so the
6819 latter will be able to retrieve it. I'm surprised this didn't
6820 segfault earlier. (Thanks to Christopher Lee.)
6822 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6824 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6827 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6829 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6830 number of stack narrowing specifier pairs. The first specifier in
6831 a pair controls inner border, the second the outer border. A
6832 number means cut that number of frames, a procedure object means
6833 cut until that object is found in operator position in a frame.
6835 * root.c (cwdr): Bugfix.
6837 * read.c: Recording of positions disabled by default.
6839 * procs.c (scm_closure_p): New function.
6841 * posix.c (scm_tmpnam): New function.
6843 * load.c: Added #include "throw.h".
6844 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6847 * load.c, load.h (scm_read_and_eval_x): New function.
6849 * eval.c: Renamed debug option "deval" to "debug".
6851 (scm_eval_x): `eval!' is no longer accessible from the scheme
6852 level. Motivation: We can't allow operations which introduce
6853 glocs into the scheme level. Guile's type system can't handle
6854 these as data. Use `eval' or `read-and-eval!' as replacement.
6856 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6857 SCM_CONSP since this is a macro!; Set vframe.prev to
6858 scm_last_debug_frame instead of 0. In this way we can look
6859 "above" the virtual start stack frame if we wish.
6860 (scm_debug_hang): New function: Useful for debugging Guile in
6861 certain tricky situations. Will probably be removed later...
6863 * debug.h: Changed semantics of debug option "backtrace". This
6864 option now only indicates whether we want automatic backtrace at
6867 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6869 * ports.c: #include "filesys.h"
6870 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6872 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6873 Motivation: This is system specific code which is related to file
6874 I/O. It also may use select. Added code by Gary Houston to
6875 detect presence of character in stdio buffers.
6877 * libguile.h: #include "libguile/libpath.h"
6879 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6880 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6881 SCM_SITE_DIR; Install libpath.h among the other include files.
6883 * load.c, load.h (scm_sys_package_data_dir): New function.
6885 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6887 * stacks.h: Bugfix: Don't use tail-array length field as stack
6888 length field! This screwed GC.
6890 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6892 * _scm.h: Added #ifndef around definition of macros min and max.
6894 * __scm.h: Added hooks for threads to plugin to in ints protection
6895 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6896 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6897 the main code in these macros duplicated and spread over multiple
6898 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6899 SCM_THREAD_SWITCHING_CODE.
6901 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6903 * snarf.h: New file.
6904 * guile-snarf.sh: New file.
6905 * Makefile.in (inner_h_files): Added snarf.h
6906 (ancillary, install, uninstall, distclean): Added actions for
6908 (.c.x): Use guile-snarf.
6909 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6910 (gen_c_files): Note that these depend on guile-snarf.
6911 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6912 now in "snarf.h". Added #include "snarf.h" to get them.
6913 * libguile.h: Added #include "snarf.h".
6914 (Patches applied and tweaked by Jim Blandy.)
6916 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6918 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6919 standards suggest against providing prototypes for system
6920 functions. Thanks to Greg Troxel.
6922 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6924 * strports.c (scm_eval_0str): New function.
6925 #include "read.h", to get prototype for scm_read.
6926 * Makefile.in (strports.o): Update dependencies.
6927 * strports.h: New prototype.
6929 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6930 scheme name from "int?" to "integer?". It seems to do the job.
6931 * numbers.h: Rename prototype too.
6932 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6935 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6936 scm_num_eq_p): Rename these according to R4RS conventions: call
6937 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6938 to making libguile R4RS compliant without ice-9...
6940 * load.c (scm_sys_search_load_path): Search for files under all
6941 extensions listed in the %load-extensions variable. If FILENAME
6942 is absolute, return it unchanged, without searching the load path.
6943 (scm_loc_load_extensions): New variable, pointing to
6944 %load-extensions' value cell.
6945 (scm_init_load): Initialize it, and the value it points to.
6946 (scm_primitive_load_path): Improve error reporting.
6948 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6949 of new Scheme variable %load-hook.
6950 (scm_primitive_load): Apply %load-hook to filename.
6952 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6954 * configure.in: add tests for figuring out whether buffered data
6955 is available in a FILE structure, which is needed by char-ready.
6957 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6960 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6961 exceptions using misc_error instead of syserror. It seems a bit
6962 odd to throw an exception if a string can't be found in the
6963 environment, but it's consistent with open-file, stat etc.
6964 (simpos.h): remove sys_ from getenv.
6966 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6967 occurs, throw an error instead of returning errno. Return value
6969 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6971 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6973 * filesys.c (scm_stat2scm): derive file type and permissions from
6974 the stat mode and append them to the returned vector.
6975 There isn't much overhead in doing this and it avoids the need to
6976 work with S_IRUSR et al. in Scheme.
6977 Define symbols scm_sym_regular etc.
6978 (scm_init_filesys): don't intern S_IRUSR etc.
6980 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6981 and s_primitive_load_path.
6983 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6985 * error.h: don't declare error symbols. prototype for scm_misc_error.
6987 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6990 * error.c: use SCM_SYMBOL to set up error keys.
6991 scm_misc_error: new procedure.
6993 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6995 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6996 between `#!' and `!#' is ignored.
6997 (skip_scsh_block_comment): New function.
6999 * feature.c (scm_set_program_arguments): New argument, FIRST.
7000 * feature.h: Update prototype.
7001 * init.c (scm_boot_guile_1): Pass new argument to
7002 scm_set_program_arguments.
7004 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7006 * init.c (scm_start_stack): Don't initialize scm_progargs here.
7007 (scm_boot_guile): Call scm_set_program_arguments here, later than
7008 the old initialization.
7010 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
7011 initialization procedure.
7012 - Delete in, out, err arguments; there are other perfectly good
7013 ways to override these when desired.
7014 - Delete result argument; this function shouldn't ever return.
7015 - Rename init_func argument to main_func, for less confusion.
7016 - Delete boot_cmd argument; main_func is more general.
7017 -Add 'closure' argument, to help people pass data to main_func
7018 without resorting to global variables.
7019 - Abort if reentered; don't bother returning an error code.
7020 - Call scm_init_standard_ports to set up the default/current
7021 standard ports; no need to pass them to scm_start_stack.
7022 - Remove code to evaluate the boot_cmd, and start the repl; let
7023 the user do something like that in main_func if they want.
7024 - Remove code to package up a return value; main_func can do any
7026 - Call exit (0), instead of returning.
7027 (scm_start_stack): Don't initialize the I/O ports here; that's
7028 weird. Delete in, out, err arguments. Move guts to
7029 scm_init_standard_ports, scm_stdio_to_port.
7030 (scm_init_standard_ports): New function, to set up current and
7031 default standard ports.
7032 (scm_start_stack, scm_restart_stack): Make these static.
7033 * init.h (scm_boot_guile): Adjust declaration.
7034 (scm_start_stack, scm_restart_stack): Remove externally
7035 visible declarations for these.
7036 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
7038 * fports.c (scm_stdio_to_port): New function. Its guts used to be
7039 written out several times in scm_start_stack.
7040 * fports.h: New declaration for the above.
7042 * feature.c (scm_set_program_arguments): New function.
7043 * feature.h: New declaration for the above.
7045 * ports.c: Formatting tweak.
7047 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
7049 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
7050 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
7051 for obtaining the address of a car or cdr field. Motivation:
7052 &SCM_CXR make assumptions about the internal structure of the
7055 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
7056 Motivation: see SCM_CXRLOC.
7058 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
7059 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
7060 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
7061 Motivation: Safer use. Some other macros are defined in terms of
7062 these operations. If these are defined using the SCM_SETCXR
7063 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
7064 to inefficiency and an <e1> with side-effects could potentially
7065 break. Also, these particular operations are heavily utilized in
7066 the garbage collector. In unoptimized code there will be a
7069 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
7070 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
7071 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
7072 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
7073 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
7074 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
7075 vports.c: Cleaned up use of pairs: Don't make any special
7076 assumptions about the internal structure of selectors and
7077 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
7078 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
7079 (Among other things, this change makes it easier to build Guile
7080 with certain compilers which have problems with casted lvalues.)
7082 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7084 * stacks.c: Improve selection of relevant stack frames when making
7085 a stack object. Introduce one level of indirection in the stack
7086 object to make it possible to "narrow" to a certain region of the
7087 stack. This facilitates making use of more clever algorithms (not
7088 implemented) for selecting relevant frames and gives a cleaner
7089 design since selection of frames can be done independently of
7090 extraction of frames from the real stack.
7091 (scm_stack_id): Also take #t as argument which means look at
7094 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
7095 Turn n_tail into an integer directly representing current number
7096 of frames in stack. Add field tail.
7098 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
7100 * debug.c (scm_make_memoized): Made it available at scheme level.
7101 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
7102 SCM_NIMP before applying heavier predicates in argument checking.
7103 (scm_local_eval): Also take memoized object as argument.
7105 * backtrace.c (scm_display_error): Just a safety measure: Stacks
7106 aren't created with zero length, but should such a strange
7107 creature suddenly turn up...
7109 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
7111 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
7112 `del', for the sake of C++ compilers. (Patch applied by JimB.)
7114 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
7116 * variable.c (scm_make_variable): Make the name hint optional, as
7118 (anonymous_variable_sym): Renamed from variable_sym. All uses
7121 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7122 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7123 of scm_primitive_load_path was also changed to
7124 "primitive-load-path", from "%try-load-path". Callers changed.
7125 We'd like to respect the convention that a function named
7126 "try-mumble" should behave just like the function called "mumble",
7127 but return #f instead of signalling some error.
7128 * load.h: Rename prototypes.
7130 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7132 * print.c (make_print_state, grow_print_state), print.h: Modified
7133 the print state representation: Don't use a tail array for
7134 recording of circular references. Resizing of the print state
7135 structure invalidates the print state pointer. To avoid passing
7136 around an indirect print state reference to all printing
7137 functions, we instead let the print state reference a resizable
7140 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7142 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7143 Don't crash when passed an improper list terminated by a
7144 non-immediate value.
7146 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7148 Allocate data for structures on an eight-byte boundary, as
7149 required by the tagging system.
7150 * struct.c (alloc_struct): New function.
7151 (scm_make_struct, scm_make_vtable_vtable): Call it.
7152 * struct.h (scm_struct_n_extra_words): Bump to 3.
7153 (scm_struct_i_ptr): New "field".
7154 * gc.c (scm_gc_sweep): When we need to free the data, use the
7155 information stored by alloc_struct to find the beginning of the
7156 block allocated to the structure, so we can free it.
7158 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7160 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7163 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7164 (scm_debug_info): New member: id.
7166 * stacks.c: Stacks are now represented as structs; Stacks have an
7167 id given to them by `start-stack'.
7168 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7170 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7171 Changed stack representation.
7173 * debug.c (scm_procedure_name): Try procedure property `name' for
7174 compiled closures aswell.
7176 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7178 * eval.c: scm_i_name moved to gsubr.c
7179 (scm_m_define): Record names of all kinds of procedure
7180 objects. (Earlier, only closures were recorded.)
7182 * procprop.h: Added declaration of scm_i_name.
7184 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7185 (scm_make_gsubr): Record names of compiled closures.
7187 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7189 * debug.c, debug.h: Removed obsolete code.
7191 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7192 stacks.c: Renamed regs --> scm_contregs.
7194 * print.c (scm_free_print_state): Cleanup print state before
7195 returning it to pool. It is better to do it here than in
7196 scm_prin1 since scm_prin1 is called often.
7198 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7199 s_set_source_property_x): Check that first argument is a pair or a
7202 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7203 scm_i_line, scm_i_column and scm_i_breakpoint global.
7205 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7206 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7209 * debug.h: Added debug object smob declaration and macro
7212 * configure.in: Build with backtrace.o and stacks.o if debug
7215 * Makefile.in: Added entries for new files: backtrace.c,
7216 backtrace.h, stacks.c and stacks.h.
7218 * symbols.c (scm_sym2ovcell): Fixed documentation.
7220 * _scm.h (min, max): Added.
7222 * async.c: Moved `min' macro to _scm.h.
7224 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7225 SCM_BACKTRACE_INDENT.
7227 * eval.c: Added new debug options `maxdepth' and `indent'.
7229 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7231 * print.h: Added selector SCM_PRINT_STATE.
7233 * print.c: New functions: scm_make_print_state,
7234 scm_free_print_state.
7236 * print.h: Added declarations for scm_make_print_state,
7237 scm_free_print_state.
7239 * debug.c (scm_m_start_stack): New acro.
7241 * debug.h: Small cleanup.
7243 * init.c (scm_boot_guile_1): Moved scm_init_debug below
7246 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

7271 More prototype-related changes from Marius Vollmer:
7272 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7273 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7274 * ports.h (ptobfuns): Added prototypes. This means some casting in
7276 * fports.c: Added casts for initializations, since the functions
7277 are defined to take FILE * as their stream argument, not SCM.
7278 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7279 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7280 to `char *str_data' to conform to prototype.
7282 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7284 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7286 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7288 * stime.c, stime.h: use SCM_P method.
7290 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7292 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7293 be given at least two arguments. Insist that lst's last element
7294 be a list, but don't make any requirements of its predecessors.
7296 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7298 * eval.c (scm_nconc2last): Revert last change; there seems to be
7299 other stuff going on here.
7301 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7303 * eval.c (scm_nconc2last): Make sure that each element of lst
7304 (which is a list of argument lists, except for the tail) is a
7305 proper list, i.e., finite and terminated by '().
7307 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7309 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7312 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7313 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7316 * vectors.c (scm_make_vector): Fill vectors with the undefined
7317 value, to help make Guile Scheme code more portable to other
7320 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7321 * symbols.h, tags.h: Doc fixes.
7323 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7325 * async.c (scm_take_signal): Doc fixes.
7327 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7329 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7330 want to subtract it from the modulus; we just want to leave it
7333 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7335 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7338 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7340 * throw.c (scm_catch_apply): Finished implementation of
7343 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7345 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7347 (scm_init_filesys): set "i/o-extensions" feature.
7350 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7352 * Makefile.in (root.o): Correct dependencies.
7354 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7356 * Makefile.in: Added dependency entry for root.o.
7358 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7359 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7361 * init.c (scm_start_stack): Set initial root continuation number
7364 * procs.c: New function: scm_thunk_p.
7366 * procs.h: Added declarations of scm_thunk_p.
7368 * root.c: Renamed `call-with-new-root' -->
7369 `call-with-dynamic-root'.
7370 (cwdr): Removed allocation of new root state. This should be done
7371 separately by use of scm_make_root.
7372 (scm_apply_with_dynamic_root): New function: Does what it
7373 sounds like. Needed when spawning threads.
7375 * root.h: Added member last_debug_frame to root state.
7376 Added #include "libguile/debug.h"
7378 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7379 arguments. The motivation is that code in root.c needs catch
7380 functionality, and we want to avoid code duplication.
7381 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7382 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7383 handlers that run without popping the stack into the dynwind
7386 * throw.h: Added prototypes for scm_catch_apply and
7389 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7391 * root.h (scm_root, scm_set_root): Decouple thread support details
7392 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7393 SCM_SET_THREAD_LOCAL_DATA.
7395 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7396 and tortoise scanning loop.
7398 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7400 * Makefile.in: Rebuild dependencies.
7402 * libguile.h: #include "libguile/print.h" before "smob.h", since
7403 the latter uses the print_state structure.
7405 * throw.c (scm_ithrow): Use the correct variable when checking to
7406 see if a given element of scm_dynwinds is a valid catch.
7408 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7409 structure, abort; don't just silently ignore the garbage.
7411 * _scm.h: #include "print.h" here, since it seems to be used just
7413 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7414 strports.c, unif.h: Don't #include "print.h".
7416 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7418 * feature.h (scm_loc_features): Removed external declaration.
7419 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7421 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7423 * feature.c (scm_init_feature): Added threads feature (needs to be
7424 initialized here, since features doesn't exist when
7425 scm_init_threads is called).
7427 * libguile.h: Added #include "libguile/../threads/threads.h".
7428 (This is a kludge to get thread support working. This should be
7431 * configure.in, acconfig.h: Added flags for thread support.
7433 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7436 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7437 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7440 * _scm.h: Added conditional #include "threads.h"
7442 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7443 SCM_THREADS_SWITCHING_CODE.
7445 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7446 allocate the basic dynamic root object.
7447 (scm_boot_guile): Added call to scm_init_root.
7449 * root.c, root.h: Added root smob.
7450 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7451 functions: Implements dynamic roots mostly according to spec in
7452 SCM manual. Main difference is that the second argument is a
7453 throw handler rather than an error "thunk".
7455 * root.h: Added declaration of scm_init_root.
7457 * root.c: Added #include "genio.h", #include "smob.h", #include
7458 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7460 (scm_init_root): Added #include "root.x".
7462 * throw.c: Added #include "stackchk.h"
7463 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7464 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7465 can be used in scm_call_with_new_root; Added reenabling of stack
7466 checking when catching a throw.
7468 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7470 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7472 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7473 element is not found, as per R4RS.
7475 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7477 * list.c: Doc fixes throughout.
7479 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7481 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7482 declare the char * to be const. Avoids a warning in rgx.c.
7484 * ports.h: spelling fix.
7486 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7489 * load.c (scm_sys_try_load_path): throw an error if file not found
7490 (like it says it in NEWS).
7492 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7494 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7495 PROPS slot to '(), not #f; it's an empty alist.
7497 * throw.h, throw.c: Use SCM_P instead of #if hair.
7499 Remove special support for uncaught throws; see throw.c for
7501 * throw.c (uncaught_throw): New function.
7502 (scm_ithrow): Call uncaught_throw if we don't find a throw
7503 target; don't mess with scm_bad_throw_vcell.
7504 (scm_bad_throw_vcell): Variable deleted.
7505 (scm_init_throw): Don't initialize it.
7507 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7510 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7512 * numbers.c (scm_istr2int): If the number is short (as most
7513 numbers are), just call scm_small_istr2int to deal with it.
7514 (scm_small_istr2int): New function, created by un-#ifdefing the
7515 non-bignum version of scm_istr2int and renaming it.
7517 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7519 * load.c (scm_sys_try_load): don't check whether value returned
7520 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7521 Change the Scheme name from %try-load to primitive-load.
7523 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7524 Can avoid passing a message, allowing it to be derived in the
7525 error handler (e.g., if we want to throw to the key both from
7528 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7530 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7531 references now have a new appearance which is more compact and
7532 also gives a clue about what the target of the reference is.
7533 By setting parameters in the print state, more fancy printing can
7534 be achieved. This is used by the (not yet commited) backtrace
7537 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7539 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7542 * print.c: Added #include "struct.h". Removed function
7545 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7546 scm_iprin1. Removed prototype for scm_prlist.
7548 * arbiters.c (prinarb),
7549 async.c (print_async),
7550 debug.c (prindebugobj, prinmemoized),
7551 eval.c (prinprom, prinmacro),
7552 filesys.c (scm_fd_print, scm_dir_print),
7554 mallocs.c (prinmalloc),
7555 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7556 smob.h (scm_smobfuns),
7557 srcprop.c (prinsrcprops),
7559 unif.c, unif.h (scm_raprin1, rapr1),
7560 variable.c (prin_var): Changed argument `int writing' to
7561 `scm_print_state *pstate'.
7563 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7564 that it will be called before scm_init_print.
7566 * print.c (scm_prin1): Print states are now allocated when calling
7567 scm_prin1 and then passed around to all printing functions as an
7568 argument. A cache `print_state_pool' enables reuse of print
7570 (scm_make_print_state): New function.
7571 (scm_iprin1): Adaption to print states.
7572 (scm_iprlist): An initial "hare and tortoise" scan brings down
7573 time complexity to O (depth * N). (Better time complexity will be
7574 achieved when the printing code is completely rewritten.)
7576 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7578 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7579 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7580 it gets done whether or not the cache variable has a value.
7582 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7584 Distinguish #f and ().
7585 * __scm.h: #undef SICP.
7586 * pairs.h (SCM_EOL): Delete this definition, equating it with
7588 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7589 the value it used to have. Doc fixes, too.
7591 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7593 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7594 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7595 Lord's implementation of structs, allowing for tail arrays as
7596 described in the manual. Also fixed some bugs. (Both the interface
7597 and the implementation should be improved.)
7599 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7601 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7602 People who whish to see the source can do `(print-enable 'source)'.
7603 Removed #ifdef DEBUG_EXTENSIONS.
7605 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7607 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7608 integer (assuming for now accepting an integer is a good thing).
7610 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7611 %S will be used instead for write'ing arguments.
7613 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7614 asserts. fix a few other asserts.
7615 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7616 scm_uniform_vector_ref, scm_array_set_x,
7617 scm_dimensions_to_unform_array): change args in
7618 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7619 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7620 scm_substring_fill_x): likewise.
7621 gsubr.c (scm_gsubr_apply): likewise.
7622 eval.c (SCM_APPLY): likewise.
7624 * eval.c (4 places): replace scm_everr with lgh_error or
7627 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7628 scm_memory_error): new procedures.
7629 scm_everr: deleted. can use scm_wta, dropping first two args.
7630 scm_error: convert NULL subr to SCM_BOOL_F.
7632 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7635 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7638 * error.c, error.h: new error keys: scm_arg_type_key,
7639 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7641 scm_wta: reimplement using lgh_error instead of scm_everr.
7643 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7645 * gdbint.c: scm_lread now has one more argument.
7647 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7648 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7649 loading source from non-file ports, which, e. g., happens when
7650 using the Emacs interface).
7652 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7655 * read.c: Added code for recording of positions of source code
7656 expressions; New functions: recsexpr, scm_lreadrecparen;
7657 _scm_make_srcprops --> scm_make_srcprops
7658 (scm_flush_ws): Removed updating of positions counters. This work
7659 is already done by scm_gen_getc
7661 * read.h: Added prototype for scm_lreadrecparen
7663 * print.c: Added #include "alist.h"
7665 * eval.c: Added #include "hash.h"
7667 * eq.c: Added #include "ramap.h"
7669 * options.c: Documentation fixes.
7671 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7672 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7673 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7674 --> scm_make_srcprops
7676 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7677 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7678 function calls in the definition of the whash access macros.
7680 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7682 * init.c (scm_boot_guile): Add level of indirection to
7683 scm_boot_guile_1() to ensure that stack base pointer is properly
7684 initialized. There was no guarantee that variable i was the
7685 highest/lowest variable on stack (i.e. the call frame of
7686 scm_boot_guile was not completely protected from gc).
7688 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7690 * ports.h (scm_port_table): put back file_name, it will be used to
7691 support debugging. Undo related changes in fports.c, ioext.c,
7694 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7696 * ports.h (scm_port_table): remove file_name member for now, it seems
7698 * fports.c (scm_open_file): don't set file_name in PTAB.
7699 (prinfport): don't use file_name in PTAB.
7700 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7701 * ports.c (scm_add_to_port_table): don't intialize file_name.
7702 (scm_port_file_name): remove for now.
7703 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7705 * fports.h (scm_mkfile): prototype deleted.
7706 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7708 * debug.c, unif.c: use scm_out_of_range instead of
7709 wta for range errors (ASSERT still needs work).
7711 * error.c, error.h (scm_out_of_range): new procedure.
7713 * error.c, error.h (scm_out_of_range_key): new key.
7715 * posix.c (scm_sync): #else was missing.
7717 * error.c, error.h: append _key to names scm_num_overflow and
7720 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7721 of consing an empty list.
7722 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7723 of macros, saves code and string space.
7724 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7725 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7726 lower case. Rename scm_syserror_m to scm_syserror_msg.
7727 error.h: prototypes for new procedures.
7729 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7731 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7733 * error.c, error.h: setup scm_num_overflow key.
7735 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7736 Remove definition of SCM_OVSCM_FLOW.
7738 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7740 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7741 explicit message and args.
7743 * error.c, error.h, __scm.h: change system_error_sym to
7746 * error.c (system_error_sym): remove leading %% from the Scheme name
7749 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7751 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7753 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7754 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7755 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7756 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7757 renamed. (These were introduced by unsupervised name
7760 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7762 * print.c: Added code for detection of circular references during
7763 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7764 a hook for printing of closures (accessible via print options).
7765 This leads to a split of calls to scm_iprin1 into two classes:
7766 elementary print operations (e. g. the code which prints a smob)
7767 still use scm_iprin1 while top level calls (like scm_display) use
7768 scm_prin1. scm_prin1 begins by clearing the data structure used
7769 to record reference information.
7771 * print.h: Added declarations of scm_prin1 and scm_prlist.
7773 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7775 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7777 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7779 * error.c (err_head): scm_iprin1 --> scm_prin1
7781 * debug.c: Adjusted header comment.
7785 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7787 * strerror.c: Doc fix.
7789 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7791 * gdbint.c (gdb_read): Now possible to run during GC.
7792 (unmark_port, remark_port): New functions.
7794 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7796 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7797 of allocating a new string object. Also, increase size by
7798 the factor 2 instead of 1.5.
7800 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7802 * __scm.h (SCM_P): Corrected to run under traditional C.
7804 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7807 * async.c: Calls to scm_sysintern corrected.
7809 * async.h (scm_async_clock): Redundant declaration removed.
7811 * continuations.c (scm_dynthrow): Redundant declaration removed.
7813 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7814 Definition typos corrected.
7816 * debug.h: Missing declarations of functions in debug.c added
7819 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7820 Missing declarations to functions in eval.c added.
7822 * filesys.c: Possibly uninitialized variable rv.
7824 * gc.h (scm_object_addr, scm_unhash_name): Missing
7825 declarations of functions defined in gc.c added.
7827 * genio.c: Possible typos str_data -> wstr_data. ???
7829 * genio.c: Possibly unintended shadowing of local variable
7830 `int c' (gotos out of scope of inner `c'). ???
7832 * init.c: Uninitialized `SCM last' may be used.
7834 * ioext.h: (scm_sys_isatty_p): Typo.
7836 * list.h (scm_list_head): Missing prototype for function in
7839 * numbers.c (scm_two_doubles): Changed from extern to static
7840 (is used only within numbers.c).
7842 * numbers.h: Repeated declarations removed.
7844 * ports.h (scm_close_all_ports_except): Declaration for the
7845 function defined in ports.c added.
7847 * posix.h: Missing declarations added.
7849 * procs.h (scm_make_subr_opt): Missing declaration added.
7851 * socket.h (scm_sys_gethost): Missing declaration added.
7853 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7855 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7856 Missing declarations added.
7858 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7860 * struct.c: Uninitialized variable `SCM answer' may be used.
7862 * unif.c (l2ra): Declaration prototype.
7864 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7865 defined in ramap.c).
7867 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7868 Redundant declarations removed (they are in ramap.h).
7870 * variable.h (scm_make_udvariable,
7871 scm_make_undefined_variable): Declaration corrected to
7872 correspond variable.c.
7874 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7875 Missing declarations added.
7877 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7879 * Makefile.in (distclean): Don't forget to delete fd.h.
7881 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7883 * fd.h.in, tags.h: Trivial cleanups.
7885 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7886 marksweep.h just declared functions from gc.c.
7887 * gc.h, libguile.h: Don't #include "marksweep.h".
7888 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7889 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7890 dependencies updated.
7892 * libguile.h: Don't #include "files.h"; it's been deleted.
7894 * files.c (scm_sys_delete_file): Moved to filesys.c.
7895 File is now empty; deleted.
7897 * filesys.c: scm_sys_delete_file is now here. Remove
7898 #if's; they seem to rely on remnants of an old portability
7899 regimen. If the problems come up again, solve them properly,
7900 using autoconf. Specifically: Don't test M_SYSV, and #define
7901 remove to be unlink if it's #defined; don't use remove just
7902 because HAVE_STDC_HEADERS is #defined.
7903 * filesys.h: Add declarations for scm_sys_delete_file.
7904 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7905 files.o, files.h, files.c, and files.x.
7906 * init.c: Don't #include "files.h", and don't call scm_init_files.
7908 Use SCM_P instead of PROTO; the latter intrudes on the user's
7910 * params.h: Deleted; definition of SCM_P moved to...
7911 * __scm.h: ... here, where it replaces PROTO macro.
7912 * libguile.h, smob.h: Don't #include "params.h".
7913 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7914 smob.h: Fix prototypes accordingly.
7915 * Makefile.in: Update dependencies.
7916 (inner_h_files): Remove params.h.
7918 * gc.c: #include "gc.h"; every module should include its header,
7919 to let the compiler cross-check the declarations against the
7922 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7923 simpos.h: #include "libguile/__scm.h".
7925 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7927 * init.c: Don't forget to #include smob.h and init.h.
7928 * Makefile.in: Dependencies updated.
7930 * smob.h: Use PROTO instead of #if __STDC__.
7932 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7934 * __scm.h: Doc fixes.
7936 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7937 <angles>; this allows `make depends' to work properly.
7939 * libguile.h: #include smob.h and pairs.h before the others; they
7940 define typedefs used by other headers.
7942 C files should #include only the header files they need, not
7943 libguile.h (which #includes all the header files); the pointless
7944 recompilation was wasting my time.
7945 * Makefile.in (all .o dependency lists): Regenerated.
7946 * libguile.h: Don't try to get a definition for size_t here...
7947 * __scm.h: Do it here.
7948 * _scm.h: Since this is the internal libguile header, put things
7949 here that all (or a majority) of the libguile files will want.
7950 Don't #include <libguile.h> here; that generates dependencies on
7951 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7952 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7953 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

7989 "unif.h", "throw.h", "tag.h", "symbols.h", "struct.h",

8049 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
8050 * weaks.c: Get "weaks.h".
8052 * stackchk.h: #include "libguile/debug.h",
8054 * print.h, read.h: #include "options.h", since everyone who uses
8055 either of these files will need that.
8057 * smob.h: #include "ports.h", "genio.h", and "print.h", since
8058 anyone who uses this file will need them to define the smob
8059 printing functions. Also, get markers.h, since people will need
8060 to #define the mark functions.
8062 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
8063 * ports.h: ... to here.
8065 * ports.h (scm_port_table_size): Explicitly give type as 'int';
8066 don't rely on archaic C default type rules.
8068 * fports.h: #include "libguile/ports.h", since you need that in
8069 order to parse this.
8071 * genio.h: #include "libguile/print.h", because you need that to
8072 parse this; don't bother #including "ports.h", since print.h gets
8075 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
8077 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
8078 this; it's now a reference to an element of *scm_root.
8080 * debug.h: Don't #include "options.h"; the compiler won't be able
8081 to find that once the headers are installed; instead, #include
8082 "libguile/options.h".
8083 * gc.h: Same, with marksweep.h.
8084 * mbstrings.h: Same, with symbols.h.
8085 * scmhob.h: Same, with _scm.h.
8086 * smob.h: Same, with params.h.
8088 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
8089 C files; there's no need for this, and it forces recompilations
8092 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
8094 * error.c (scm_error): declare scm_error_callback.
8096 * error.h: prototype for scm_error_callback.
8098 * __scm.h: define lgh_error.
8099 (SCM_SYSERROR): redefine using lgh_error.
8101 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
8103 * error.c (scm_error): new procedure.
8105 * error.h: prototype for scm_error.
8107 * Makefile.in (install): install scmconfig.h from the current
8108 directory, not $(srcdir).
8110 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8112 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8113 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8114 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
8115 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,

8120 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8121 vports.h, weaks.h: #include "libguile/__scm.h", not
8122 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
8123 dependencies are within libguile properly.
8125 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8127 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8128 when scmconfig.h doesn't exist.
8130 * load.c (scm_sys_try_load): Correct spelling.
8132 * feature.c (scm_loc_features): Make this static.
8134 * Makefile.in (libpath.h): Omit trailing slash from path. We
8135 shouldn't require it of users, so why put it here?
8137 Move code to initialize and search %load-path from ice-9 to C
8138 code, so we can use the load-path to find the ice-9 boot code;
8139 this makes it easier to run Guile without installing it. See
8140 corresponding changes in guile/Makefile.in.
8141 * feature.c: Move stuff concerned with the load path to load.c.
8142 (scm_compiled_library_path): Deleted.
8143 Don't #include libpath.h here.
8144 * feature.h: Don't mention scm_compiled_library_path.
8145 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8146 <sys/stat.h>, and <unistd.h> (if present).
8147 (R_OK): #define if the system hasn't deigned to.
8148 (scm_loc_load_path): New variable.
8149 (scm_init_load_path, scm_sys_search_load_path,
8150 scm_sys_try_load_path): New functions.
8151 (scm_init_load): Initialize scm_loc_load_path to point to the
8152 value cell of the Scheme %load-path variable.
8153 * load.h: Add declarations for scm_sys_search_load_path,
8154 scm_sys_try_load_path.
8155 * init.c: Call scm_init_load_path.
8156 * Makefile.in (feature.o, load.o): Dependencies updated.
8158 * load.c, load.h: Rewrite using PROTO macro.
8160 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8162 * gc.c (scm_cellp): New function: C predicate to determine if an
8163 SCM value can be regarded as a pointer to a cell on the heap.
8165 * gc.h: Added declaration of scm_cellp.
8167 * gdb_interface.h: New file: The GDB interface header from the GDB
8170 * gdbint.c: New file: GDB interface.
8172 * gdbint.h: New file: GDB interface.
8174 * libguile.h: Added #include <libguile/gdbint.h>.
8176 * init.c (scm_boot_guile): Added scm_init_gdbint.
8178 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8179 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8180 found if object files and source are kept separate).
8182 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8184 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8186 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8188 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8189 TK_SRC_DIR; they're not relevant any more.
8191 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8192 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8194 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8196 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8197 search path, so we can find the <libguile/MUMBLE.h> headers.
8199 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8201 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8202 implicit in the .c.o rule.
8203 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8206 Put the library path in a header file, instead of passing it on
8207 the command line in every compilation.
8208 * Makefile.in (libpath.h): New target.
8209 (feature.o): Depend on libpath.h.
8210 (clean): Delete libpath.h.
8211 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8212 * feature.c: ... #include "libpath.h" here.
8213 * .cvsignore: Ignore libpath.h.
8215 Don't install the unwashed masses of Guile header files in the
8216 main #include path; put most of them in a subdirectory called
8217 'libguile'. This avoids naming conflicts between Guile header
8218 files and system header files (of which there were a few).
8219 * Makefile.in (pkgincludedir): Deleted.
8220 (innerincludedir): New variable; this and $(includedir) are enough.
8221 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8222 (installed_h_files): Divide this up. Now this variable lists
8223 those header files which should go into $(includedir) (i.e. appear
8224 directly in the #include path), and ...
8225 (inner_h_files): ... this new variable says which files appear in
8226 a subdirectory, and are referred to as <libguile/mumble.h>.
8227 (h_files): List them both.
8228 (install): Create innerincludedir, not pkgincludedir. Put
8229 the installed_h_files and inner_h_files in their proper places.
8230 (uninstall): Corresponding changes.
8231 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8232 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8233 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8234 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,

8237 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8238 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8239 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8240 vports.h, weaks.h: Find __scm.h in its new location.
8241 * __scm.h: Find scmconfig.h and tags.h in their new locations
8242 (they're both "inner" files).
8244 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8246 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8248 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8250 * posix.c: Doc fixes.
8252 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8254 * socket.c: Don't include a prototype for inet_aton; just use a
8255 K&R style declaration, to avoid warnings but minimize the chance
8256 of conflicts with the system.
8258 On NextStep, <utime.h> doesn't define struct utime, unless we
8259 #define _POSIX_SOURCE before #including it.
8260 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8261 * acconfig.h: New comment text for above CPP symbol.
8262 * configure.in: Call it.
8263 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8265 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8267 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8268 testing for __EMX__.
8270 * posix.c: #include <libc.h>, if it exists.
8272 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8273 don't even know if the latter exists.
8275 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8276 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8277 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8279 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8281 (scm_init_posix): Use them when initializing the Scheme constants
8284 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8286 * Makefile.in (libdir, includedir, bindir): Use the
8287 autoconf-supplied values, instead of deriving them ourselves.
8288 (pkgincludedir, datadir, pkgdatadir): New variables.
8289 (install, uninstall): Put the header files in a special
8290 subdirectory, not in the main search path.
8292 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8293 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8295 * Makefile.in (IMPLPATH): Deleted; never used.
8297 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8298 on the Tcl/Tk source any more.
8299 (INCLUDE_CFLAGS): Remove references to the above.
8301 * Makefile.in (version.o): Corrected dependencies.
8303 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8305 * libguile.h: #include "version.h"
8307 * init.c (scm_boot_guile): Call scm_init_version.
8308 * gscm.c (gscm_run_scm): Call scm_init_version.
8310 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8311 GUILE_VERSION): AC_DEFINE these.
8312 (acconfig.h): #undef the above symbols.
8314 * Makefile.in (libobjs): Add version.o.
8315 (installed_h_files): Add version.h.
8316 (c_files): Add version.c.
8317 (gen_c_files): Add version.x.
8318 (version.o): New rule.
8319 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8320 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
8321 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
8322 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
8323 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
8324 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
8325 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
8326 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
8327 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
8328 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
8329 weaks.o): Add version.h to dependency lists.
8330 (markers.o): Remove duplicate rule.
8332 * version.h: New file.
8334 * version.c: New file.
8336 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8338 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8339 array; use it appropriately. Since GCC is quite happy to
8340 subscript functions, it never warned us about this; we should use
8341 -Wpointer-arith in the future. I guess we never tested
8344 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8346 * socket.c: Doc and copyright fixes.
8348 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8350 * debug.c: Fixed and improved gdb support.
8352 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8354 * socket.c: Added declaration of inet_aton to avoid compiler
8355 warning. (Hope this solution is correct.)
8357 * stime.c: Added declaration of ftime. (This is missing in
8360 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8362 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8364 * Makefile.in (c_files): add strerror.c.
8366 * strerror.c: new file from Emacs' sysdep.c.
8367 maybe configure should also check for sys_errlist.
8369 * configure.in (AC_REPLACE_FUNCS): add strerror.
8371 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8373 * debug.c (scm_init_debug): Added initialization for
8374 scm_evaluator_traps.
8376 * debug.h, debug.c: Various name changes.
8377 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8378 "debug-options-interface". See commentary in options.c.
8380 * options.h, options.c: Options now have documentation strings.
8381 Also added a long explanatory commentary.
8383 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8386 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8387 last_debug_info_frame is now updated in all cases.
8389 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8392 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8394 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8395 Added option STACK_CHECKING.
8397 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8399 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8401 * __scm.h: Removed symbols for debugging support.
8403 * acconfig.h: Added symbols for debugging support.
8405 * configure.in: Added user option for debugging support.
8406 --enable-debug will include the debugging code into libguile.a.
8408 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8409 scm_relocate_chunk_to_heap.
8411 * debug.c: New file: low-level debugging support. It also
8412 includes support for debugging with gdb. (The extensions to gdb
8413 are written by Per Bothner at Cygnus.)
8415 * debug.h: New file: low-level debugging support.
8417 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8418 argument pairs. Extensive modifications to the debugging
8419 evaluator. Added "SECTION:" commentaries to clarify what happens
8420 when, during double compilation. Renamed EVALIMP --> EVALIM.
8421 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8422 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8423 the beginning of the file. New procedure: scm_unmemocopy.
8424 Added some global state variables needed by the debugging
8425 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8426 check_entry, check_apply, check_exit, debug_options and
8427 evaluator_traps. New acro: undefine.
8429 * eval.h: Renamed EVAL --> XEVAL.
8431 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8432 --> scm_make_weak_key_hash_table.
8434 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8435 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8437 * libguile.h: Conditionally include debug.h
8439 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8440 scm_object_properties shouldn't return handle. `handle' now gets
8441 initialized in scm_set_object_properties_x. scm_object_properties
8442 doesn't any longer create an entry in scm_object_whash.
8444 * options.c: New file: handling of run time options.
8446 * options.h: New file: handling of run time options.
8448 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
8450 * print.c: New procedure: scm_print_options
8452 * print.h: Defines for print options.
8454 * read.c: New procedure: scm_read_options
8456 * read.h: Defines for reader options.
8458 * root.h: Added scm_source_whash among scm_sys_protects.
8460 * srcprop.c: New file: source properties.
8462 * srcprop.h: New file: source properties.
8464 * throw.c (jbsmob): Jump buffers are now correctly allocated.
8465 (Bug found by A. Green.)
8467 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8469 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8471 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8473 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8475 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8476 and should be called by the final client.
8478 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8480 * gc.h: Use the PROTO macro when declaring functions.
8481 * gc.c: Use the PROTO macro when declaring static functions.
8482 Remove the CPP hair around function definitions.
8484 * gc.c (scm_init_storage): Initialize scm_asyncs.
8486 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8487 preprocessor symbol; "__scm.h" is where it might get #defined.
8488 * __scm.h: Similar: #include <scmconfig.h> before testing
8491 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8493 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8495 * init.c (scm_boot_guile): Add init_func argument; call
8496 (*init_func) instead of calling scm_appinit; it's ucky to
8497 hard-code names for the user's procedures.
8498 * init.h (scm_boot_guile): Adjust declaration.
8500 * __scm.h (PROTO): New macro, for declaring functions with
8503 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8504 eliminate all the __STDC__ conditionals.
8505 (scm_boot_guile): Add declaration.
8506 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8507 Remove __STDC__ conditionals around function definitions; the
8508 declarations in init.h will provide the same information, more
8511 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8512 complain about it in the error message; the error message is
8513 adequate without that note, and there's nothing the user can do
8516 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8518 * Makefile.in (ancillary): Drop def.sed.
8520 * posix.c (scm_init_posix): Use numeric values, rather than
8521 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8522 F_OK. The symbols aren't available on some systems, and I'm
8523 pretty sure their values are fixed by common widespread practice.
8524 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8526 More functions unavailable on some systems.
8527 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8528 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8530 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8531 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8532 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8533 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8534 stub that signals an error as the #else.
8536 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8538 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8540 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8542 * unif.c: include ramap.h.
8544 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8546 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8548 * ports.c: include sys/ioctl.h.
8550 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8552 * configure.in: check for sys/ioctl.h.
8554 * ports.c: include <malloc.h> not "malloc.h".
8556 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8558 * fports.c: remove ttyname and tmpnam declarations.
8560 * posix.c: fewer ttyname declarations.
8562 * fports.c: include <string.h> not "string.h".
8564 * init.c, ioext.c: include string.h and unistd.h.
8566 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8568 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8569 genio.c, simpos.c, vports.c: include string.h.
8571 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8573 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8575 (scm_addr_buffer_size): change type from scm_sizet to int.
8576 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8577 from scm_sizet to int.
8579 * error.c: include unistd.h.
8581 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8584 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8586 * __scm.hd, def.sed: deleted.
8588 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8590 Changes for NeXT, suggested by Robert Brown.
8591 * configure.in: Call AC_TYPE_MODE_T.
8592 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8593 NeXT. Put header file list in alphabetical order.
8594 * configure, scmconfig.h.in: Regenerated.
8595 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8597 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8600 * acconfig.h: New file, providing documentation for the CPP
8601 symbols defined in configure.in
8602 * acconfig-1.5.h: Removed; superceded by the above.
8604 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8606 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8608 * fports.c (scm_open_file): don't return #f, throw error.
8610 * ioext.c (fileno): renamed from %fileno.
8611 (soft-fileno): deleted.
8613 * ports.c (scm_port_revealed): don't need to check for -1 from
8615 (scm_set_port_revealed_x): return unspecified, not #f.
8617 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8619 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8621 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8623 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8625 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8627 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8628 This is necessary on Ultrix, and doesn't hurt portability.
8630 * Makefile.in (dist-dir): New target, implementing a new dist system.
8631 (installed_h_files): Put in alphabetical order.
8632 Remove duplicate entries for markers.h and unif.h.
8633 (c_files): Remove duplicate entries for markers.c.
8634 (ancillary): Renamed from anillery; all uses changed. Remove
8635 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8636 Remove all the ../doc/* files; doc/Makefile.in handles that.
8638 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8640 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8641 every if must have an else, or else the whole command has a
8642 non-zero exit code whenever the if's condition is false.
8644 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8646 * posix.c: include string.h.
8648 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8650 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8653 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8654 Remove leading % from scheme names.
8655 Do not return error values, call SCM_SYSERROR or similar.
8657 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8659 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8661 * struct.c (scm_init_struct): new file.
8663 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8665 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8666 (scm_list_head): added list-head for rapidly chopping argument
8667 lists off of longer lists (and similar).
8669 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
8671 * objprop.c (scm_object_property): assq the cdr of the whash
8672 handle for obj, not the handle itself.
8674 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8676 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8677 weak hash tables last of all marking to avoid an obscure gc bug.
8678 WARNING: circular lists stored in a weak hash table will hose us.
8680 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8682 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8683 new functions similar to scm_substring_move_left_x and
8684 scm_substring_move_right_x.
8686 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8688 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8691 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8693 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8695 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8697 * strports.c (scm_strprint_obj): convenience function. C for
8698 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8700 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8701 removed to a separate library
8703 * init.c (scm_boot_guile): copied from guile-tcl.c.
8704 Initialization specific to tcl interpreters removed.
8706 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8708 * ports.c (scm_ports_prehistory): size malloced here doesn't
8709 matter so long as it is non-0 (got rid of "* 4").
8711 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8713 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8714 since its definition was bogus).
8716 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8718 * mallocs.[ch]: back again (for rx at least).
8720 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8722 * ports.c: removed functions relating to the mapping between ports
8723 and descriptors. (That stuff is unix-specific and should be collected
8724 in a separate library).
8726 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8727 (Tom Mckay@avanticorp.com)
8729 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8731 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8732 handled correctly (SCM_FREEP was applied to them) -- test for
8733 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
8734 being overwritten with #f. (brown@grettir.bibliotech.com)
8736 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
8738 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
8739 for a specific symbol or for all symbols.
8741 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
8743 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
8744 keys and weak values confused).
8746 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
8748 * list.c (scm_last_pair): map '()=>'()
8750 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
8752 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
8753 Generalized assoc and hash-table functions.
8754 Factored pairs.c into multiple files.
8756 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
8758 * gscm.c (gscm_run_scm): got rid of objprop.
8760 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
8762 * genio.c (scm_getc):
8763 NOTE: fgetc may not be interruptable.
8765 * procprop.c (scm_stand_in_scm_proc):
8766 NOTE: don't use a alist here.
8767 (scm_set_procedure_properties_x): fix type checking throughout this file.
8769 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
8771 * ports.c (scm_remove_from_port_table): adjust scm_mallocated

8901 initialization to fix a race condition.
8903 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
