1 1999-10-26 Mark Galassi <rosalia@lanl.gov>
3 * gh.h, gh_data.c (gh_symbol2scm): changed gh_symbol2scm() to take
4 a const char * argument, upon suggestion from Lynn Winebarger.
6 1999-10-26 Gary Houston <ghouston@freewire.co.uk>
8 * strports.c (st_end_input): avoid dubious pointer arithmetic.
10 1999-10-24 Gary Houston <ghouston@freewire.co.uk>
12 * Move the responsibility for resetting port buffers from the
13 caller of the ptob seek procedure to the implementation. This
14 gives more control in general to the ptob seek: in particular the
15 change of 1999-10-20 can be made to work without breaking seek on
16 string ports. There's a comment in NEWS about upgrading port
19 * ports.c (scm_seek): don't reset the port buffers here.
21 * fports.c (fport_seek): reset the buffers, except for the
24 * strports.c (st_end_input): (bug fix): decrement pt->read_pos by
25 offset. check that it's not less than read_buf.
26 (st_seek): reset the buffers first, unless it's the 0 SEEK_CUR
27 case and currently reading.
29 1999-10-20 Gary Houston <ghouston@freewire.co.uk>
31 * ports.c (scm_seek): Add a special case for SEEK_CUR, offset 0,
32 so that unread chars are not needlessly discarded. (thanks to
35 1999-10-18 Gary Houston <ghouston@freewire.co.uk>
37 * fports.c (scm_fdes_to_port): always set rw_random if the fdes is
38 random access. rw_active needs to be maintained even for single
39 directional ports, otherwise scm_seek and probably other things are
40 broken. (thanks to Roland Orre).
42 * strports.c (scm_mkstrport): set rw_random to 1 unconditionally.
44 * ports.c (scm_add_to_port_table): initialise rw_random to 0.
46 * ports.h (scm_port): change the comments on rw_random and rw_active.
48 1999-10-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
50 * ioext.c: Added #include "feature.h".
52 These changes turns `delay' into a memoizing macro. This is
53 because it may be expanded before evaluation if it occurs at the
54 beginning of a body. (Thanks to Lauri Alanko.)
56 * eval.c, eval.h (scm_sym_delay): New global symbol.
58 * tags.h (SCM_IM_DELAY): New immediate symbol.
60 * print.c (scm_isymnames): Printed representation.
62 * eval.c (unmemocopy, SCM_CEVAL): Handle SCM_IM_DELAY.
63 (scm_m_delay): Turned into a memoizing macro.
65 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version.
67 1999-10-11 Jim Blandy <jimb@savonarola.red-bean.com>
69 * gh_data.c (gh_ints2scm, gh_doubles2scm): Make sure elements are
70 protected from GC while building the vector. (Thanks to Bernard
71 Urban and Greg Harvey.)
73 1999-10-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
75 * throw.c (handler_message): Display backtrace if backtraces
78 1999-10-05 Jim Blandy <jimb@savonarola.red-bean.com>
80 * Makefile.in, scmconfig.h.in: Deleted from CVS repository. Run
81 the autogen.sh script to create generated files like these.
83 * numbers.c (scm_string_to_number): Signal an error if radix is
84 less than two. (Thanks to Jorgen Schaefer.)
86 * print.c (scm_write, scm_display, scm_newline, scm_write_char):
87 Don't assume that the current output port is valid. Somebody
88 might close it. (Thanks to Bernard Urban.)
90 1999-10-02 Jim Blandy <jimb@zwingli.cygnus.com>
92 * scmconfig.h.in: Regenerated.
94 * Makefile.am (EXTRA_libguile_la_SOURCES): fix typo.
96 Mon Sep 27 17:15:14 1999 Greg J. Badros <gjb@cs.washington.edu>
98 * __scm.h: Fix a bunch of macros that were missing do-while(0)
101 * debug.c, eval.c: Fix buggy uses of SCM_ALLOW_INTS (missing
102 semicolon) exposed by the above change.
104 1999-09-27 Greg J. Badros <gjb@cs.washington.edu>
106 * stacks.c: Avoid compiler warning re: unitialized var.
108 * scmconfig.h.in: Added DEBUG_FREELIST
110 * pairs.h: Fix macro that was not do-while(0) sandwiched.
112 * gc.h, gc.c: Added scm_gc_set_debug_check_freelist_x,
115 1999-09-23 Gary Houston <ghouston@freewire.co.uk>
117 * ioext.c (scm_init_ioext): enable "i/o-extensions" feature here
118 instead of in scm_init_filesys.
120 * init.c (scm_boot_guile_1): don't call scm_init_posix or
121 scm_init_filesys unless HAVE_POSIX is defined.
122 don't call scm_init_netdb or scm_init_socket unless
123 HAVE_NETWORKING is defined.
125 * Makefile.am (EXTRA_libguile_la_SOURCES): filesys.c, posix.c,
126 net_db.c, socket.c: moved here from libguile_la_SOURCES.
128 1999-09-25 Jim Blandy <jimb@savonarola.red-bean.com>
130 * root.c (scm_make_root): Initialize all the fields of the new
131 root. GC could happen any time, you know. (Thanks to Greg
134 * numbers.c (scm_number_to_string): Signal an error if radix is
135 less than two. (Thanks to Jorgen Schaefer.)
137 * Makefile.am (EXTRA_libguile_la_SOURCES): Add memmove.c here,
138 so automake will actually generate rules for it.
139 * Makefile.in: Regenerated.
141 1999-09-21 Jim Blandy <jimb@savonarola.red-bean.com>
143 * backtrace.c: #include "_scm.h" before testing whether
144 HAVE_UNISTD_H is #defined.
146 1999-09-20 Jim Blandy <jimb@savonarola.red-bean.com>
148 * read.c (scm_read): Don't assume that scm_cur_inp is always open.
149 * ports.c (scm_read_char): Same.
150 * ioext.c (scm_read_line): Same.
151 (Thanks to Bernard Urban.)
153 1999-09-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
155 * vectors.c (scm_vector_move_right_x): Bugfix: Remove side effect
157 numbers.c: Removed #ifndef SCM_RECKLESS at places where type
158 checking may invoke a generic. (Thanks to Michael Livshin.)
160 * __scm.h (SCM_WTA_DISPATCH_0, SCM_GASSERT0): New macros.
162 * numbers.c (scm_max, scm_min, scm_sum, scm_difference,
163 scm_product, scm_divide): Bugfix: Don't pass SCM_UNDEFINED to the
164 generic function if the asubr is called with only one arg.
166 1999-09-20 Gary Houston <ghouston@freewire.co.uk>
168 * scmsigs.c (scm_sigaction): add SA_RESTART to flags only if
169 HAVE_RESTARTABLE_SYSCALLS.
170 (scm_init_scmsigs): use siginterrupt if it's available. not
171 everyone who has restartable syscalls has SA_RESTART it seems.
173 (scm_sigaction): use scm_num2long/scm_long2num when converting
174 SIG_DFL/SIG_IGN, in case it doesn't fit in an INUM. use
175 scm_integer_p to test the type.
177 1999-09-18 Gary Houston <ghouston@freewire.co.uk>
179 * _scm.h, scmsigs.c: replace HAVE_RESTARTS with
180 HAVE_RESTARTABLE_SYSCALLS.
182 * strports.c (scm_strport_to_string): create the string from
183 pt->read_buf instead of an expression that evaluates to the
186 * gdbint.c (gdb_print): don't just use SCM_CHARS to get a C string
187 from the port: the port's buffer may not be NUL terminated.
189 1999-09-16 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
191 * Makefile.am (.c.x): Added missing semicolon after `false'.
193 1999-09-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
195 * print.c (scm_iprin1): Turn `write' and `display' into
196 primitive generics and use their associated generic functions in
197 scm_iprin1 for GOOPS objects.
199 * backtrace.c: #include <unistd.h> if present.
201 1999-09-14 Jim Blandy <jimb@savonarola.red-bean.com>
203 * Makefile.am (.c.x): Don't create a subshell just to delete the
204 .x file and return false.
205 * Makefile.in: Regenerated.
207 1999-09-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
209 * feature.c (scm_create_hook): New function. Replaces
210 scm_make_named_hook which is now deprecated.
211 (scm_make_hook_with_name): New primitive.
212 (print_hook): Hooks now print in a fancy way.
214 1999-09-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
216 * __scm.h, backtrace.c, backtrace.h, debug.c, debug.h, dynl-dld.c,
217 dynwind.c, dynwind.h, eval.h, evalext.c, evalext.h, feature.c,
218 feature.h, hashtab.c, hashtab.h, objects.c, objects.h, print.c,
219 procs.c, procs.h, smob.c, smob.h, srcprop.c, strorder.c, struct.c,
220 struct.h: Updated copyright notices.
222 * srcprop.c (scm_source_property): Bugfix: Use SCM_NECONSP instead
223 of SCM_NCONSP. (Thanks to Greg Badros.)
225 * gsubr.c (scm_make_gsubr): Use scm_make_subr_opt for creation of
228 * eval.c, debug.h (SCM_BACKTRACE_WIDTH): New debug option: width.
230 * backtrace.c: Keep backtraces within specified width by
231 adaptively adjusting fancy printing parameters and cut output if
233 (scm_display_application): Check args.
235 1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
237 Change the name of the objects returned by OPENDIR from
238 "directory" to "directory stream". A predicate named "directory?"
240 * filesys.c (scm_directory_stream_p): Renamed from scm_directory_p.
241 At the Scheme level, "directory?" -> "directory-stream?".
242 (scm_dir_print): Use the phrase "directory stream" in printed form.
243 * filesys.h (scm_directory_stream_p): Prototype renamed
246 * Makefile.am (CLEANFILES): Remove versiondat.h; that should only
247 be removed by `make distclean', since it's generated by configure.
248 * Makefile.in: Regenerated.
249 (Thanks to Robert Bihlmeyer.)
251 * strop.c (scm_substring_move_x): Signal an error if start1
252 doesn't come before end1. (Thanks to Karoly Lorentey).
254 * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
255 calling SCM_NIMP. (Thanks to Karoly Lorentey).
257 * version.c (scm_libguile_config_stamp): Deleted. See
258 corresponding change to ../ice-9/boot-9.scm.
259 * versiondat.h.in: Remove definition for GUILE_STAMP.
260 * version.h: Delete prototype.
261 * Makefile.in: Regenerated.
263 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
265 * filesys.c (scm_directory_p): new procedure "directory?" Returns
266 a boolean indicating whether its argument is a directory
267 port as returned by opendir (thanks to Dirk Herrmann for the
270 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
272 * backtrace.c (display_frame_expr): Don't print a newline.
273 (display_frame): Print the newline here instead.
274 (display_backtrace_body): Don't print "Backtrace:".
275 (scm_backtrace): Print "Backtrace:" here instead.
277 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
279 * procs.c (scm_setter): Signal WTA if handed an entity or operator
282 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
283 primitives. (Thanks to Greg Badros);
284 (scm_hook_to_list): New primitive; Hooks are now smobs.
286 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
288 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
289 of #f for the 10th vector element to avoid an exception
290 seen by Bernard Urban.
291 (scm_mktime): unneeded ASSERT removed.
293 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
295 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
298 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
300 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
302 * numbers.c: Converted comparison operations to dispatch on
303 generic if args don't match.
305 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
307 1999-09-06 James Blandy <jimb@mule.m17n.org>
309 * guile-snarf.c: Deleted. Snarfing should respect CPP
310 conditionals, so it needs to actually run CPP. Bleah.
312 1999-09-05 James Blandy <jimb@mule.m17n.org>
314 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
315 * guile-snarf.in: Be sure to exit with an error if CPP does.
316 * Makefile.am (.c.x): Delete the .x file and exit with an error
317 status if guile-snarf exits with an error status.
318 * Makefile.in: Regenerated.
320 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
321 scm_makekey, which doesn't exist any more. Guess nobody's using
324 * guile-snarf.c: New implementation of guile-snarf, meant to be
325 more robust than the shell script. I think it's complete, but I
326 haven't tested it at all, and I haven't changed the build process
327 to actually use it. We should compare its output against that of
328 the existing shell script, for all source files.
330 * guile-snarf.c (parse_args): Abort if we haven't handled some
333 1999-09-03 James Blandy <jimb@mule.m17n.org>
335 * load.c (scm_search_path): If the filename has any extension at
336 all, ignore the entire list of extensions. Also, don't check whether
337 the file is accessible. If the file exists, accessible or not, we
338 should return it. Inaccessible files should cause an error later.
339 (Thanks to Keisuke Nishida for the suggestions.)
341 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
343 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
344 atexit not available. (sunos4.1.4 needs it.)
346 1999-09-01 James Blandy <jimb@mule.m17n.org>
348 I take it all back --- bcopy does handle overlapping source and
349 destination areas correctly. At least on every system I could
350 find. But it is better to use AC_REPLACE_FUNCS than to introduce
351 new CPP conditionals.
352 * memmove.c: New file, implementing memmove in terms of bcopy.
353 * scmconfig.h.in: Regenerated.
355 Allocators should use the `void *' type for generic pointers.
356 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
357 argument and return types.
358 * gc.h: Corresponding changes to prototypes.
361 1999-08-31 James Blandy <jimb@mule.m17n.org>
363 * numbers.c (scm_init_numbers): Claim to support the `complex'
364 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
366 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
367 find (ice-9 boot-9) when Guile was compiled in a separate
368 directory from the source. (Thanks to Rodney Brown.)
369 * Makefile.in: Regenerated.
371 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
372 table lengths by the size of a single element when growing the
373 table. (Thanks to Bill Schottstaedt.)
375 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
377 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
378 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
379 since that cuts down the time for type dispatch by 50%.
381 1999-08-30 James Blandy <jimb@mule.m17n.org>
383 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
384 not a correct substitute for memmove, because it doesn't handle
385 overlapping source and destination areas on many platforms.
386 Overlaps are the primary reason to use memmove in the first place.
387 * ports.c (scm_ungetc): Same.
388 * strop.c (scm_substring_move_x): Same.
390 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
392 * gc.c (scm_init_storage): Skip registration of cleanup on systems
393 which lack atexit. (Is it important that cleanup is made
394 properly? Maybe we should replace all `exit' with `scm_exit' and
397 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
398 scm_struct_free_standard, scm_struct_free_entity): Declared to
399 return scm_sizet instead of size_t.
401 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
402 there on sunos4.1.4.)
404 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
406 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
407 Account for the case when second argument is unbound.
409 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
410 (Thanks to Karoly Lorentey.)
412 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
413 isn't present. (Thanks to Suzuki Toshiya.)
415 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
418 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
421 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
422 Bernard Urban and Ian Grant.)
424 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
425 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
426 change in the representation of entities and operators.)
428 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
430 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
431 don't allocate zero bytes (thanks to Bill Schottstaedt).
433 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
435 * procs.c (scm_setter): Converted to use generic dispatch.
437 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
440 * load.c (scm_search_path): Don't try extensions which already are
441 present at the end of the filename.
442 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
444 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
446 Cleanup and simplification of generic method dispatch.
447 Also, the quadruple representation of entity and operator
448 procedures has been replaced with single.
450 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
452 * print.c (scm_isymnames): Removed #@hash-dispatch.
454 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
455 from eval.c; Support 0 arity methods.
456 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
457 (scm_apply_generic_env): Removed.
458 Replaced slots proc0-3 with procedure.
460 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
461 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
462 SCM_OPERATOR_PROCEDURE.
463 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
464 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
466 * struct.c, struct.h: Replace 4 procedure slots with one.
467 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
469 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
472 * eval.c (scm_sym_args): Removed.
473 (SCM_CEVAL): Simplified entity application.
474 Moved dispatch code to objects.c.
476 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
478 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
480 * sort.c (closureless): Use scm_eval_body.
482 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
483 with a symbol as last form was first called normally and then via
484 `map' or some other mechanism using primitive apply, an ILOC was
487 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
489 This change extends the representation of primitive procedures
490 with more data fields, e.g. a place for documentation and true
491 procedure properties.
493 * procs.c, procs.h (scm_subr_entry): New type: Stores data
494 associated with subrs.
495 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
496 SCM_SUBR_DOC): New macros.
497 (scm_subr_table): New variable.
498 (scm_mark_subr_table): New function.
500 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
502 * gc.c (scm_gc_mark): Don't mark subr names here.
503 (scm_igc): Call scm_mark_subr_table.
506 This change implements a scheme for letting a generic work as a
507 shadow for a primitive procedure. If the primitive procedure
508 can't dispatch on its arguments, control is left over to the
509 generic. Normal wrong type arg errors will be generated until the
510 user has hung the first method on the primitive.
512 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
514 * procs.c, procs.h (scm_subr_p): New function (used internally).
516 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
518 * objects.c, objects.h (scm_primitive_generic): New class.
520 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
522 * print.c (scm_iprin1): Print primitive-generics.
524 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
525 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
527 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
528 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
529 primitives). NOTE: This means that it is now *required* to use
530 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
531 obscured representation that will be removed in the future anyway,
532 so backward compatibility is no problem here).
534 * numbers.c: Converted most numeric primitives (all but bit
535 comparison operations and bit operations) to dispatch on generic
539 Better support for applying generic functions.
541 * eval.c, eval.h (scm_eval_body): New function.
543 * objects.c (scm_call_generic_0, scm_call_generic_1,
544 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
548 Optimization of the generic function dispatch mechanism.
550 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
551 called scm_memoize_method instead of doing a second lookup.
553 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
558 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
559 scm_sysintern so that the binding connected with the subr name
560 isn't cleared when we give set = 0.
563 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
565 More transparent handling of ports with print states.
567 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
568 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
569 instead of a pair of a port and a print state. We'll need to cons
570 once extra in scm_printer_apply but the type system will be
571 cleaner, it will mix better with GOOPS, and, it will be even more
572 transparent to the user.
574 * print.c (scm_get_print_state): New procedure: Given an output
575 port, return the print state associated to it in the current print
576 chain, if one exists;
577 (scm_port_with_print_state): New procedure: Associate a
578 print-state with a port.
579 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
580 (scm_printer_apply): Wrap port and pstate as a smob;
581 (print_state_printer): Removed.
583 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
585 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
588 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
589 testing (otherwise the port-print-state trick won't be transparent
590 to the user; one example where this caused problems was in the
591 (ice-9 format) module).
593 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
595 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
596 SCM_UNSPECIFIED instead of the set value.
598 1999-08-20 James Blandy <jimb@mule.m17n.org>
600 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
602 * ports.h (enum scm_port_rw_active): New enum, containing
603 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
604 zero). The debugger knows about enums, but doesn't know about
606 (typedef scm_port): Declare rw_active member to be an enum
608 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
610 * ports.c (scm_add_to_port_table): Same.
611 * strports.c (st_flush, st_end_input): Same.
613 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
614 scm_must_realloc, and scm_done_malloc as appropriate.
616 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
618 * sort.c (quicksort): Added condition to protect the algorithm
619 from crashing the interpreter if the less predicate is buggy.
621 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
623 * fports.c (fport_write): fix line-buffering mode again.
624 (scm_open_file): recognise 'l' for line-buffering.
625 (scm_setvbuf): recognise _IOLBF for line-buffering.
627 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
629 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
632 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
635 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
637 * fports.c (fport_write): use memcpy instead of strncpy, in case
638 the data contains NUL.
640 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
642 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
644 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
645 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
646 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
647 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
648 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
649 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
650 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
651 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
652 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
653 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
654 scm_sym_ as prefix for symbols.
656 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
658 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
659 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
660 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
661 scm_sym_atcall_cc): Made global.
663 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
665 * eval.c (scm_sym_args): Made global.
667 * objects.c (scm_set_object_procedure_x): Disallow setting of
668 procedures for pure generic functions.
670 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
672 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
673 Scheme name from lseek to seek, but lseek was added recently so
674 it shouldn't be a big problem.
675 * ports.c, gdbint.c, ioext.c: changed callers.
677 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
679 * fports.c (fport_input_waiting): if select is used, return 1
680 instead of whatever FD_ISSET expands to. maybe it will be useful
681 to interpret the value from the input_waiting ptob procedure as a
682 lower bound on the number of bytes available.
684 * Mikael asked for a few names to be changed...
686 * ports.c (scm_make_port_type): take the write procedure as the
687 second argument instead of the flush procedure.
688 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
689 fflush -> flush, read_flush -> end_input, fclose -> close,
690 fill_buffer -> fill_input, ftruncate -> truncate,
691 input_waiting_p -> input_waiting.
693 * ports.c (end_input_void_port): was read_flush_void_port.
694 (scm_set_port_end_input): was scm_set_port_flush_input.
695 (scm_set_port_flush): was scm_set_port_write.
696 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
697 (scm_end_input): was scm_read_flush.
698 (scm_fill_input): was scm_fill_buffer.
699 (scm_flush): was scm_fflush.
700 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
701 (fport_end_input): was local_read_flush.
702 (fport_flush): was local_fflush.
703 (fport_close): was local_fclose.
704 (fport_truncate): was local_ftruncate.
705 (fport_seek): was local_seek.
706 (fport_free): was local_free.
707 (fport_fill_input): was fport_fill_buffer.
708 * strports.c (st_end_input): was st_read_flush.
709 (st_truncate): was st_ftruncate.
710 * vports.c: (sf_flush): was sfflush.
711 (sf_close): was sfclose.
712 (sf_fill_input): was sf_fill_buffer.
714 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
717 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
719 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
720 forms now contain the expressions to be dispatched upon instead of
721 depending on a surrounding lambda or let; Generic function
722 dispatch has been optimized; `apply' on a generic function now
723 works a little bit strangely. It uses a trick so that the type
724 dispatch code in SCM_CEVAL can be reused.
726 * objects.h, objects.c (scm_apply_generic_env): Added (used by
728 (scm_operator_p): Added.
729 (scm_sym_atdispatch): Added.
730 (scm_set_object_procedure_x): Modified to handle the new style
732 (scm_object_procedures): New debugging procedure.
734 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
736 * eval.c, eval.h (scm_sym_args): Added.
738 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
740 * feature.c, feature.h (scm_c_run_hook): Added.
742 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
743 cdrxnoap and loopnoap instead of begin and loop.
745 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
747 * ports.c (scm_putc, scm_puts),
748 * unif.c (scm_uniform_array_write): use scm_lfwrite.
749 * ports.c (scm_putc): change type of first argument from int to char.
751 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
753 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
754 SCM_IM_HASH_DISPATCH.
756 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
757 (scm_si_redfined, scm_si_hashsets): Moved.
759 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
760 flag which combines type and status info so that the class
761 redefinition protocol has zero cost during normal execution.
763 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
765 * ports.h (scm_ptob_descriptor): include a write procedure again.
766 it's more efficient for unbuffered fports (e.g., sockets.)
768 * ports.c (scm_puts): use ptob->write.
769 * vports.c (scm_make_sfptob): set write proc in ptob.
770 * strports.c (scm_make_stptob): set write proc in ptob.
771 * ports.c (write_void_port): new procedure.
772 * vports.c (sf_write): new procedure.
773 * ports.c (scm_lfwrite): use ptob->write.
774 * strports.c (st_write): new procedure.
775 * fports.c (fport_write): new procedure.
776 (scm_make_fptob): set write in ptob to fport_write.
777 * ports.h: prototype for scm_set_port_write.
778 * ports.c (scm_make_port_type): initialise ptob write procedure.
779 (scm_set_port_write): new proc.
781 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
783 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
784 until we've verified that it is actually a port. (Thanks to
787 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
789 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
790 code, particularly an unnecessary test (len != size, where len ==
791 size). (Was this leftovers from debugging code, or have I missed
794 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
795 size. (Thanks to James Dean Palmer.)
797 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
798 (Thanks to Lorentey Karoly.)
800 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
802 * eval.c (scm_m_expand_body): Use scm_cons_source.
804 * struct.c (scm_print_struct): Use vtable name.
806 * print.c (scm_init_print): Set name of print state type.
808 * stacks.c (scm_init_stacks): Set name of stack type.
810 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
812 * eval.c (SCM_CEVAL): Removed old implementation of internal
815 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
817 * debug.c, debug.h (scm_reverse_lookup): Added.
818 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
819 internal procedure definitions; Don't use scm_i_inner_name.
821 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
824 * eval.h: Added prototypes for multi language support functions.
826 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
827 improper lists in the low-level representation, since that will
828 cause a begin to be prepended at macro expansion.
830 * eval.c (scm_cons_source): Version of cons which copies source
831 properties from an existing cell.
832 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
834 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
835 procedure source before calling scm_unmemocopy instead of faking
838 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
840 Ported `internal defines' fix from SCM. Original ChangeLog entry:
842 1998-07-09 Radey Shouman <radey@colorage.com>
844 * eval.c (ceval_1): Modifications to allow rewriting of interal
845 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
846 body of which it is the CAR is macro expanded by m_expand_body,
847 which rewrites internal DEFINE.
849 (m_expand_body): Added.
851 (m_macroexp1): Added argument to control error checking:
852 m_expand_body may speculatively expand forms in the wrong
853 environments. Made argument number checks conditional on
856 (m_body): Added, error checks bodies and inserts the ISYM tokens.
858 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
861 (m_cond): (m_case): (m_quote): Modified to avoid destructively
862 changing their argument forms. Since m_expand_body
863 speculatively macro expands forms the process must be
866 (m_ident_eqp): Fixed to use proper environment.
868 (renamed_ident): Added DEFER_INTS_EGC.
870 Added prototypes for static functions.
876 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
877 is false, do not produce an error for unbound variables, return a
878 pointer to cell_undef instead.
880 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
884 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
885 destructively changing their argument forms. Since m_expand_body
886 speculatively macro expands forms the process must be reversible.
888 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
889 SCM_IM_LET introduced by named lets.
891 (scm_m_letstar): Use scm_m_body instead of bodycheck.
893 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
894 scm_letrec. scm_letrec1 does not check for a null binding and
895 takes an additional argument to specify the ISYM of the body. Use
896 scm_m_body instead of bodycheck.
898 (scm_m_let): Use scm_m_body instead of bodycheck.
900 (scm_m_expand_body, scm_macroexp): New.
902 (unmemocopy): Account for ISYMs introduced by scm_m_body.
904 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
905 check=1. Throw error for internal defined that have not been
906 rewritten by scm_m_expand_body.
908 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
909 Removed prototype for SCM_APPLY.
911 * tags.h: Added extern declaration of scm_isymnames.
913 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
915 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
917 * lang.c: New file: Beginning of multi-language support.
919 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
921 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
922 (scm_dynamic_wind): Added argument checking for the after guard so
923 that we don't add garbage on the dynwind chain.
924 (scm_swap_bindings): Added.
926 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
927 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
928 (scm_isymnames): New isyms for multi-language support.
930 * eval.c (scm_nil, scm_t): New symbols.
931 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
932 forms for multi-language support.
934 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
936 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
938 Renamed functions in the random function library interface
939 from scm_i_XXX --> scm_c_XXX.
941 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
943 * ports.c (scm_putc): fix line-buffering.
945 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
947 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
948 scm_set_ptob_XXX --> scm_set_port_XXX.
950 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
952 * ports.c, ports.h (scm_make_port_type): New interface for
953 creation of port types (replaces scm_newptob). Just as for the
954 smobs, we need to separate the internal representation of smob
955 types from the interface, so that we easily can add new fields and
956 rearrange things without caring about backward compatibility.
957 This change was forced by the need in GOOPS to create classes
958 representing port types.
959 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
960 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
961 scm_set_ptob_seek, scm_set_ptob_truncate,
962 scm_set_ptob_input_waiting_p): New setters.
963 (scm_newptob): Rewritten to use scm_make_port_type. For backward
965 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
966 (scm_prinport): Removed.
967 (scm_port_print): Added.
968 (scm_print_port_mode): Added.
969 (void_port_ptob, print_void_port, close_void_port, noop0):
970 Removed. Removed #include "genio.h" Added #include "objects.h",
973 * fports.c (prinfport): Moved code from ports.c.
975 (scm_fptob): Removed. Instead use new interface.
976 (scm_make_fptob): Added. (Need to create basic ports in a
977 specific order in ports.c.)
979 * strports.c (scm_stptob, prinstpt, noop0): Removed
980 (scm_make_stptob): Added.
982 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
983 (scm_make_sfport): Added.
985 * filesys.c (scm_dir_print): Don't use the port printing code.
986 Instead provide specific directory printer.
988 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
990 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
993 * smob.c (scm_smob_print): Handle non-existing type name nicely.
994 Removed #include "genio.h"
996 * objects.c (scm_make_port_classes): New function ptr.
998 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
1000 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
1002 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
1003 allow the 1st argument to be a fdes or filename as well as a
1004 port (as in the filesys.c version).
1006 * filesys.c (scm_truncate_file): removed.
1008 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1010 * readline.c, readline.h: Removed.
1012 * objects.c, objects.h (scm_port_class): Added.
1013 (scm_class_of): Look up port class in scm_port_class.
1014 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
1015 SCM_INOUT_PCLASS_INDEX): Added.
1018 * Makefile.am: Removed genio.c, genio.x.
1022 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1024 * init.c: Make sure that scm_post_boot_init_modules is called only
1025 once. (Important when using a dumped image.; Thanks to Bernard
1028 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
1030 * guardians.c (scm_guardian_zombify): Separate scanning for
1031 zombies from marking the pairs of the free list.
1033 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
1034 use the macros. (Thanks to Michael Livshin.)
1036 * eval.c (scm_m_lambda): Let bodycheck check the body of the
1037 lambda. Let your sins be purified by the blood of the lambda.
1038 (Thanks to Eric Hanchrow.)
1040 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
1041 (Thanks to Valdis Kletnieks.)
1043 Fixes for EMX from Mikael Ståldal.
1045 * filesys.c: #include <io.h>, if we have it.
1046 * scmconfig.h.in: Regenerated.
1048 * stime.c (ftime): Delete declaration for this function --- let
1049 the system supply it.
1051 Cleanups from John Bley.
1053 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
1055 * gsubr.c: Don't include "gsubr.h" twice.
1057 Cleanups for compilation on Irix 6, from David Kaelbling.
1059 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
1060 regex_t pointer. This is what the callers have, mostly.
1061 (scm_regexp_exec): Don't forget to pass the `rx' argument to
1062 scm_regexp_error_msg.
1064 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
1065 int. That way, if we get a warning on this line, it's more likely
1066 that we're really missing bits we care about.
1068 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
1071 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
1072 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
1073 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
1074 cast at all is more appropriate in every case. At the moment, we
1075 assume everywhere that SCM is an integral type anyway.
1077 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
1079 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
1080 read_pos after scm_fill_buffer.
1082 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
1085 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
1086 fports.c (fport_fill_buffer): implement the interface change.
1088 * ports.c (scm_fill_buffer): interface change: no longer increments
1089 read_pos past the character that's returned. it seems clearer to
1090 leave it to the caller to decide what to do (thanks Jim).
1092 * vports.c (sf_fill_buffer): put the read char into the buffer
1093 as well as returning it.
1095 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

1102 (st_seek): don't allow string to be extended if seeking past
1103 the end of a read-only port.
1105 1999-07-12 Gary Houston <ghouston@easynet.co.uk>
1107 * strports.c (st_seek): change the resize checks.
1109 * ports.c (scm_ftruncate): throw error if offset works out negative.
1111 * strports.c (st_flush): increase string size in blocks of
1112 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
1113 it's greater and reset read_buf_size.
1114 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
1115 to be maintained for output ports too (it holds the written
1116 part of the string, while write_buf may have unwritten buffer
1118 (st_truncate): rewritten.
1119 (top of file): added a few notes.
1121 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
1123 Patch from Greg Badros:
1124 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
1125 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
1126 (function pointer) argument to scm_make_gsubr and scm_make_subr
1127 calls. This avoids warnings in C++ programs using guile-snarf.
1129 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
1131 * strports.c (st_grow_port): set pt->read_pos. set
1132 pt->read_buf_size one less than pt->write_buf_size if there's
1133 an unwritten char at the end of the string. similarly for
1135 (st_resize_port): renamed from st_grow_port.
1136 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
1137 seek from read_end instead of write_end for SEEK_END.
1138 (st_ftruncate): calculate current length using readbuf, not write
1140 (scm_strport_to_string): use read_buf_size for length.
1141 (stfill_buffer): don't re-initialise the readbuf.
1143 1999-07-05 Gary Houston <ghouston@easynet.co.uk>
1145 * strports.c (scm_strport_to_string): new procedure.
1146 (scm_call_with_output_string, scm_strprint_obj): use
1147 scm_strport_to_string.

1150 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1152 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)

1156 * smob.c: added scm_make_smob_type_mfpe (), scm_set_smob_mfpe ();
1157 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
1158 and "bigneg" smob types.
1160 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
1161 SCM_RETURN_NEWSMOB macro. Added protos for new functions in
1164 * *.c: Use scm_make_smob_type_mfpe, instead of scm_newsmob, and
1165 use SCM_NEWSMOB or SCM_RETURN_NEWSMOB in constructors instead of
1166 SCM_NEWCELL and setting the CAR/CDR by hand.

1250 trinary conditional in order for the flag computation to be
1253 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1255 * struct.c, struct.h:
1257 In order to support different kinds of deallocation, a destructor
1258 slot has been added to struct vtables. This allows for structs
1259 containing pointers to other memory blocks.
1261 (scm_struct_i_free): New hidden struct slot. Holds destructor for

1330 1999-06-19 Jim Blandy <jimb@savonarola.red-bean.com>
1332 Patch from Greg Harvey:
1333 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1334 around the condition of an `if', `while', etc., even if the
1335 condition is a macro invocation that expands to something
1336 surrounded by parens. It's more readable.
1338 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1339 proper lists, and of the appropriate lengths.
1340 (check_map_args): New function. (Thanks to Greg Harvey for the
1343 1999-06-19 Michael Livshin <mike@olan.com>

1362 (scm_igc): Check for underflow by seeing if this is negative.
1364 * gc.h (scm_mallocated): Fix declaration.
1365 (Thanks to Greg Harvey.)
1367 * ports.h: #include <sys/types.h>, to get a definition for `off_t'.
1369 1999-06-15 Jim Blandy <jimb@savonarola.red-bean.com>
1371 * stime.c (bdtime2c): Initialize lt->gmtoff and lt->tm_zone from
1372 sbd_time. (Thanks to Eric Hanchrow.)
1374 Fix from Ken Raeburn <raeburn@raeburn.org>:

1376 vector contents, to be used only during garbage collection.
1377 * weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
1378 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
1380 (scm_weak_size, scm_n_weak): Deleted.
1381 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
1382 vectors without allocating new storage during GC, using
1383 scm_weak_vectors as the head of the chain.
1384 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1385 instead of stepping through an array.
1386 (scm_gc_sweep): Update offset used to find start of weak vector to
1388 (scm_init_storage): Set scm_weak_vectors to EOL.
1390 Fix from Ken Raeburn <raeburn@raeburn.org>:
1391 * gc.c (already_in_gc): New variable.
1392 (scm_igc): Set and clear already_in_gc; abort if it's set at
1395 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
1397 Fix from Gary Houston:
1398 * fports.c (local_seek): Signal an error if the seek fails.
1399 * ports.c (scm_lseek): Don't check return value of port's seek
1400 function; it's its job to signal an error if there's a problem.
1402 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
1404 * strports.c (scm_call_with_output_string): Don't include the

1407 * ioext.c (scm_read_line): Switch to reading properly.
1409 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
1410 scmsigs.c, strports.c, vports.c: Install the sources which
1411 actually correspond to the changes described below. I got the
1412 ChangeLog entries and the patch from two different places...
1414 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1416 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1417 it shows up as terrible performance, as we GC constantly.
1419 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1420 newline. A bit faster, and definitely hairier.
1421 (scm_read_line): Count newlines here instead.
1423 * strings.c (scm_take_str): New function.
1424 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1425 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
1426 scm_take_str, to avoid copying the string.
1428 Add some simple-minded support for line buffered ports.
1429 * ports.h (SCM_BUFLINE): New flag for ports.
1430 * init.c (scm_init_standard_ports): Request line-buffering on
1431 the standard output port.
1432 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1434 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1435 and there's a newline to be written, flush the port.
1437 Gary Houston's open-buffer port patches:
1439 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1441 * ports.c: (scm_lseek): clear buffers even if just reading current
1444 * fports.c (local_fclose): call local_fflush unconditionally.
1445 (various): don't use the scm_must... memory procs.
1447 1999-04-25 Gary Houston <ghouston@easynet.co.uk>

1452 strports.c (scm_mkstrport): check that pos is reasonable.
1453 ioext.c (scm_ftell, scm_fseek): use lseek.
1454 (SCM_CLEAR_BUFFERS): macro deleted.
1455 ioext.c (redirect_port: use ptob fflush, read_flush.
1456 ports.h (scm_ptobfuns): add ftruncate.
1457 ports.c (scm_newptob): set ftruncate.
1459 ports.c (scm_ftruncate): new procedure.
1460 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
1461 strports.c (st_seek, st_grow_port): new procs.
1462 fports.h (scm_port): change size types from int to off_t.
1463 ports.c (scm_init_ports): initialise the seek symbols here
1464 instead of in ioext.c.
1465 strports.c (scm_call_with_output_string): start with an empty
1466 string, so seek and ftruncate can be used.
1468 gdbint.c: adjust string port usage.
1470 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1472 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1473 equivalent to fflush for the read buffer.
1474 * ports.c (scm_newptob): set read_flush.
1475 ports.c (void_port_ptob): set read_flush.
1476 fports.c (local_read_flush): new proc. add to ptob.
1477 strport.c (st_read_flush): likewise.
1478 vport.c (sf_read_flush): likewise.
1479 fports.h (struct scm_fport): remove random member. there's nothing
1480 left but fdes. leaving it as a struct to allow for future changes.
1481 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1482 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1483 ptob proc if the read buffer is filled.
1485 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1487 * ports.h (scm_port): add a rw_random member and replace
1488 reading and writing members with rw_active member.
1489 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1491 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1493 * ports.h (struct scm_port_table): add writing and reading members
1494 to replace write_needs_seek: it isn't good enough for non-fports.
1495 ports.c, ioext.c, fports.c: corresponding changes.
1496 (struct scm_port_table): give it a typedef and rename to scm_port.
1497 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1498 corresponding changes.
1500 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
1502 * ports.c (scm_newptob): bugfix: set seek member.
1503 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
1504 and generalised to all port types.
1506 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
1508 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1509 signals (it was only being done for handlers installed from Scheme).
1510 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1511 waiting for input caused an EINTR error from read.
1513 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1515 * ports.h (struct scm_port_table): make all the char members
1516 unsigned, so they convert to int without becoming negative if large.
1518 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1520 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1521 with threads enabled. rename this procedure to
1522 fport_wait_for_input and take a port instead of a fdes.
1523 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1525 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1526 get readline support working again: use fdopen to get FILE objects.
1528 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1530 * gc.c (scm_init_storage): install an atexit proc to flush the
1532 (cleanup): the new proc. it sets a global variable which can be
1533 checked by the ptob flush procs to avoid trying to throw
1534 exceptions during exit. not very pleasant but it seems more reliable.
1535 * fports.c (local_fflush): check terminating variable and if set
1536 don't throw exception.
1537 * CHECKME: that the atexit proc is installed if unexec used.
1539 * throw.c (scm_handle_by_message): don't flush all ports here.
1540 it still causes bus errors.
1542 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1543 and move to ioext.c.
1545 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1547 * ports.c (scm_char_ready_p): check the port buffer and call the
1548 ptob entry if needed.
1550 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1551 ptob initialisers. use it in char-ready
1553 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1555 * vports.c (sfflush): modified to write a char (since softports
1556 currently use shortbuf.)
1558 * fports.c (scm_standard_stream_to_port): moved to init.c and
1561 * init.c (scm_init_standard_ports): make stdout and stderr
1562 unbuffered if connected to a terminal. with stdio they
1563 were line-buffered by default.
1565 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1568 * ports.h (scm_ptobfuns): change fflush return to void.
1569 change flush proc definitions.
1571 * strports.c (scm_call_with_output_string): get size from
1572 buffer instead of port stream.
1573 (st_flush): new proc.
1575 * ports.h (struct scm_port_table): added write_end member,
1576 as an optimisation. set it where write_buf_size is set.
1578 * ports.h (struct scm_port_table): change stream from void *
1579 back to SCM. SCM presumably must be large enough to hold a
1580 pointer (and probably vice versa but who knows.)
1581 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1583 (scm_puts): rewritten
1584 * fports.c (local_ffwrite, local_fputs): removed.

1953 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1955 Most of this batch of changes is about how to deal with extended
1956 types when an object system is loaded into Guile. A nice object
1957 system is capable of representing Guile's types as class objects.
1959 For example, we want a regular expression to be of class <regex>.
1960 But regular expressions are smobs which aren't under direct
1961 control of the object system, so there has to be some mechanism
1962 which informs the object system that a new class should be created
1963 which can represent the smob type. I call this a "wrapper class".
1965 * objects.c: #include "smob.h";
1966 (scm_class_keyword): Removed. (Class is automatically created by
1968 (scm_smob_class): Array of smob classes indexed by smobnum.
1969 (scm_make_extended_class): "Plugin" function pointer for creation
1970 of wrapper classes for smob and struct types.
1971 (scm_class_of): Handle compiled closures. (Currently regarded as
1973 Use scm_smob_class to handle smob types;
1974 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1975 through scm_smob_class;
1978 * smob.c (scm_newsmob): Also create a wrapper class if
1979 scm_smob_class has been initialized.
1981 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1982 type code and smobnum.
1984 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1985 (scm_struct_table): Weak key table with auxilliary information for
1986 struct types. Currently used for names and wrapper classes.
1987 (scm_struct_ihashq): Hash function for structs.
1988 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1989 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1990 for accessing names of vtables. The record implementation in
1991 boot-9.scm currently uses the setter to record the name of record
1992 types. When the object system is initialized, it can use this
1993 information to create wrapper classes with suitable names.
1994 (scm_init_struct): Allocate scm_struct_table.
1995 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1996 (struct tags are a finite resource and we might want to restrict
1997 the use of tags to vtables only. E.g., Goops only uses tags for
1999 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
2001 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
2004 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
2005 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
2006 Used for access of struct table entries.
2008 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
2009 (scm_hash_fold): New procedure. Used to process all entries in a
2010 hash table (in no particular order).
2012 Argh! For the umpteenth time I got compilation errors because of
2013 the "intuitive" name `kw'. This has to have an end:
2015 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
2016 "kw" --> "keywords" everywhere.
2017 (I doubt that this will cause big compatibility problems since the
2018 application interface is unaffected.)
2020 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
2022 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>

2025 column inums to native form.

2032 (Used to flag certain system procedures which shouldn't turn up in
2035 * eval.c (scm_sym_system_module): New symbol. (Used to flag
2036 modules which aren't "user" modules and the code of which

2040 Extract the lookup closure from an environment.
2041 (scm_system_module_env_p): New function: Return non-#f if MODULE

2047 * debug.c (scm_procedure_name): Use name property in the default
2050 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
2052 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
2054 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
2055 procedure throughout.
2057 * print.c (scm_iprin1): Removed extraneous space when printing
2058 procedure-with-setters.
2060 Entity and operator setter slots were introduced as a complement
2061 to the <procedure-with-setter> type in order to support entities
2062 and operators with setters in a reasonable and efficient way.
2063 * procs.c (scm_procedure, scm_setter): Handle entity and operator
2066 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

2079 directly through the instance.
2081 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
2083 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
2084 scm_struct_i_flags instead of scm_vtable_index_layout!
2086 * list.c (scm_list_star): New procedure.
2088 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

2107 Readline paren matching from Greg Harvey, with modifications from
2110 * readline.c (in_readline, reentry_barrier_mutex): Make these
2113 * readline.c: #include <sys/time.h> and "iselect.h", so we can
2114 control how long we're paused, and threads will run while we're
2116 (match_paren, find_matching_paren, init_bouncing_parens): New
2118 (scm_init_readline): Call init_bouncing_parens.

2169 SYMB now point to const.
2171 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2173 * print.c (scm_iprin1): Use scm_procedure_name instead of
2174 scm_procedure_property for compiled closures.
2176 * tags.h (scm_tc7_pws): New procedure type. Four representations
2177 for procedure-with-setters were considered before selecting this
2180 1. A closure where the CODE and ENV slots are used to represent
2181 the getter and a new SETTER slot is used for the setter. The
2182 original getter is stored as a `getter' procedure property. For
2183 closure getters, the CODE and ENV slots contains a copy of the
2184 getter's CODE and ENV slots. For subr getters, the CODE contains
2187 2. A compiled closure with a call to the getter in the cclo
2188 procedure. The getter and setter are stored in slots 1 and 2.
2190 3. An entity (i.e. a struct with an associated procedure) with a
2191 call to the getter in the entity procedure and the setter stored
2192 in slot 0. The original getter is stored in slot 1.
2194 4. A new primitive procedure type supported in the evaluator. The
2195 getter and setter are stored in a GETTER and SETTER slot. A call
2196 to this procedure type results in a retrieval of the getter and a
2197 jump back to the correct eval dispatcher.
2199 Representation 4 was selected because of efficiency and
2202 Rep 1 has the advantage that there is zero penalty for closure
2203 getters, but primitive getters will get considerable overhead
2204 because the procedure-with-getter will be a closure which calls
2207 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
2208 <procedure-with-setter>, but together with rep 2 it suffers from a
2209 three level dispatch for non-GOOPS getters:
2211 cclo/struct --> dispatch proc --> getter
2213 This is because the dispatch procedure must take an extra initial
2214 argument (cclo for rep 2, struct for rep 3).
2216 Rep 4 has the single disadvantage that it uses up one tc7 type
2217 code, but the plan for uniform vectors will very likely free tc7
2218 codes, so this is probably no big problem. Also note that the
2219 GETTER and SETTER slots can live directly on the heap, using the
2220 new four-word cells.
2222 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,
2223 SCM_SETTER): New macros.

2293 function call are executed in a well defined order.
2295 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2297 * alloca.c (alloca): Cast value returned by malloc. (Thanks to

2302 * random.c: Removed alloca includes.
2304 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2306 * Makefile.in: This changed, for some reason I don't really
2307 understand, when I ran automake in the top level directory. This
2308 may be contamination by Cygnus internal releases. If you re-run
2309 automake and this change gets reverted, don't worry about it.
2311 1999-01-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2313 * sort.c, sort.h: New files: Implement slib's and scsh's sort

2338 * guardians.c, guardians.h (scm_make_guardian,
2339 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
2340 scm_get_one_zombie, scm_init_guardian): This is an implementation
2341 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
2342 David Eby (1993) "Guardians in a Generation-Based Garbage
2343 Collector" ACM SIGPLAN Conference on Programming Language Design
2344 and Implementation, June 1993 ftp://ftp.cs.indiana.edu

2355 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2357 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
2360 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2362 Move the procedure slots of entities to invisible slots (so that
2363 we can have operator class objects which themselves are entities).
2364 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
2365 SCM_STRUCTF_ENTITY): New constants.
2367 * struct.c (scm_make_struct): Allocate "invisible" room for
2368 procedures if SCM_STRUCTF_ENTITY is set in vtable.

2378 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
2380 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
2382 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
2383 of syntactic forms, similar to SCM_PROC.
2384 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
2385 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
2386 for the name symbols when needed.
2388 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
2390 * Makefile.in: Regenerated.
2392 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
2394 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
2395 take the address of _into; it might be a register. Just have
2396 scm_debug_newcell return the new cell.
2397 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2398 taking the address of a place to store it as an argument.
2399 * gc.h (scm_debug_newcell): Change declaration.
2400 (Thanks to Greg Harvey.)
2402 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

2412 (freecell): Use it to print freed objects, for slightly easier
2415 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2417 * backtrace.c (display_frame): Made more robust. Doesn't throw an
2418 error if no source properties can be found for a frame. (Thanks
2419 to Christian Lynbech.)
2421 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2423 * objects.h: Removed slots direct_supers and direct_slots from the
2424 definitions of the rudimentary classes described by objects.h.
2426 * objects.c, objects.h (scm_entity_p): New procedure. Together
2427 with the predicates scm_procedure_p and scm_struct_p, this
2428 predicate makes it possible to differ between structs, entities
2431 * modules.c, modules.h (scm_resolve_module): New function.
2433 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2435 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2436 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2439 * objects.c (scm_entity_p): New procedure.
2441 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
2442 for asubrs, rpsubrs, lsubrs and lsubr_2s.
2444 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2446 * procprop.h (scm_i_procedure_arity): Added declaration.
2448 * procprop.c (scm_i_procedure_arity): Made global; New code to
2449 handle operators and entities.
2450 (scm_procedure_property): No need to call scm_procedure_p since
2451 scm_i_procedure_arity now does all necessary type checking.
2452 Added #include "objects.h".
2454 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2455 s_add_hook_x --> s_remove_hook_x.
2456 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.

2460 (scm_make_hook): Optional argument defines number of arguments to
2462 (scm_make_named_hook): Take number of args as second arg.
2463 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2464 boot-9.scm for a while); First arg is the hook. The rest are
2465 arguments passed on to the hook procedures.
2467 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2469 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2470 scm_logbit_p): Do the computation in ulongs. This is not as nice
2471 as doing it in bignums, but at least it's good enough for
2472 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2474 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2475 subexpressions. (Thanks to Charbel Jacquin.)
2477 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2479 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2480 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2481 (scm_make_named_hook): New function.
2483 * feature.c: Added #include "eval.h".
2485 * modules.c (scm_make_module): Beautify the module.
2487 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2489 * modules.c, modules.h: New files: C interface to modules. (This
2490 is necessary in order to interface the object system to Guile
2491 properly. The guts of these modules will be replaced by the new
2492 module system in the future.)
2494 * init.c: Added #include "modules.h"
2495 (scm_boot_guile_1): Call scm_init_modules.
2496 (invoke_main_func): Call scm_post_boot_init_modules.
2498 * Makefile.am: Added modules.c, modules.x, modules.h.
2500 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2502 * procs.c: #include "objects.h"
2503 (scm_procedure_p): Return #t also on structs which are operators.
2505 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2506 <operator-metaclass> and <entity-class> to <standard-class>,
2507 <operator-class> and <entity> in order to conform with STKlos
2510 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2511 which isn't an operator.
2512 (SCM_APPLY): Ditto, but jump to badproc.
2514 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2516 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2517 Previously, structs implanted in code were interpreted as forms
2518 the operator of which was a gloc. We solve this by checking for
2519 the zero in the emulated vcell in the struct vtable. Since
2520 implanted structs always will look like forms with a gloc
2521 operator, execution will only be slowed down by maximally one
2522 extra test-and-branch per application.
2524 * evalext.c (scm_definedp): Removed check for isyms; Added a
2525 second optional argument: It is now possible to supply an
2526 evaluation environment in which to look for the symbol.
2528 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2530 * readline.c (scm_init_readline): Set
2531 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2533 * coop.c (coop_condition_variable_wait): Removed
2534 (coop_condition_variable_wait_mutex): Folded logic of
2535 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2536 prevent condvar signal lossage. Previously, another thread could
2537 start to run after unlocking the mutex but before putting the
2538 current thread on the wait queue. If that thread then would
2539 signal the first, the signal would be lost. (Thanks to Christian
2542 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2544 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2547 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2549 * objects.c (scm_i_make_class_object): Renamed from
2550 make_class_object; exported; error checking moved to
2551 scm_make_class_object and scm_make_subclass_object.
2552 (scm_make_class_object, scm_make_subclass_object): Use
2553 scm_i_make_class_object.
2554 (scm_make_subclass_object): Let the subclass have same metaclass
2557 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2559 * debug.c (scm_debug_options): Bugfix: Set the value of
2560 scm_stack_checking_enabled_p after setting debug options;
2561 #include "stackchk.h". (Thanks to Richard Polton.)
2563 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2565 * unif.c (scm_array_contents): removed unnecessary test for 0
2568 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2570 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2571 Replaced by macro `collect' in boot-9.scm.
2573 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2575 * eval.c (scm_copy_tree): Copy source properties if existent.
2577 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2578 don't, we may end up passing memoized source to a transformer.)
2580 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2582 * stack.c (get_applybody): Help function which lookups the first
2583 body form of the apply closure.
2584 (read_frames): Prevent the source of the first form of the apply
2585 closure from being recorded. This would only be confusing.
2587 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2588 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2590 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2592 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2594 (read_frames): Use SCM_MACROEXPP.
2596 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2598 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2599 don't contain interesting information since all arguments are
2600 present in the frame which applies the compiled closure anyway.);
2601 Skip the transformer application frames.
2603 * print.c (scm_iprin1): Print gsubrs as primitives.
2605 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2607 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2609 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2610 that we can identify these in a backtrace. (This change doesn't
2611 introduce any significant speed penalty.)
2613 * eval.c: Added note about `serial-map' using scm_map.
2615 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2616 readline options. They should reside in their own options array.
2618 * readline.c, readline.h (scm_readline_options,
2619 scm_readline_opts): Moved readline options here.
2621 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2623 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2624 SCM_ROCHARS instead of SCM_CHARS.
2626 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2627 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2629 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2631 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2632 This is quite important since the latter clears the
2633 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2634 every single character read...
2636 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2638 * print.c (scm_iprin1): Removed suspect looking (and indeed
2639 malevolent) semicolon after test for user supplied closure print
2640 procedure. (Thanks to Telford Tendys.)
2642 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2643 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2644 starting to search the list. Removed call to sloppy_mem_check.
2646 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2647 procedures: Same as scm_delq_x et al, but delete maximally one
2650 * options.c (scm_options, scm_init_options): GC-protect option
2651 values of type SCM. (Thanks to Telford Tendys.)
2653 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2655 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2656 make sure that there always is a "real" scm_lookupcar.
2658 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2660 * read.c, read.h (scm_read_opts): New read options
2661 "history-length" and "history-file".
2662 (scm_read_options): Stifle history to history length.
2664 * readline.c (scm_read_history, scm_write_history): New procedures.
2666 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2668 * eval.h (scm_macro_eval_x): Removed declaration.
2670 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2671 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2672 Renamed and made global.
2674 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2675 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2677 * evalext.c, evalext.h: New files. Contain non-R5RS things
2678 having to do with evaluation.
2680 * evalext.c (scm_serial_map): New procedure: Version of `map'
2681 which guarantees that the procedure is applied to the lists in
2683 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2684 returns a list of the results of the body forms instead of the
2685 result of the last body form.
2686 (scm_definedp, scm_m_undefine): Moved from eval.c
2688 * evalext.h (scm_m_sequence_to_list): Added declaration.
2690 * macros.c, macros.h: New files.
2691 (scm_procedure_to_syntax, scm_procedure_to_macro,
2692 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2693 scm_macro_name, scm_macro_transformer): Moved from eval.c
2694 (scm_make_synt): Moved from eval.c
2696 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2698 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2701 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2703 * debug.c, print.c: Added #include "macros.h".
2705 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2707 This change adds the ability to use `unread-char' multiple times
2708 without interspersed reads and adds the new procedure
2709 `unread-string'. The change is optimized for the common case of
2710 unreading a single character. This is also the reason behind the
2711 choice to store characters in the port itself: in most cases no
2712 extra malloc is required.
2714 The amount of code in some macros in ports.h has been increased to
2715 the extent that they would fit better as C functions, but, since
2716 this code belongs to the port representation, such functions
2717 should be placed in ports.c which would cause calls back and forth
2718 between ports.c and genio.c. That is not good for performance.
2719 Also, keeping them as macros allows the compiler to do some
2720 optimizations which are needed to make the current interface
2721 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2723 One benchmark (Guile startup time) indicates an increase of
2724 loading speed of 1%. Another (reading (using `read') boot-9.scm
2725 10 times) shows no change in performance.
2727 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2728 made to find a beautiful solution.)
2730 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2731 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2732 character. (SCM_CLRDY clears all.)
2733 (SCM_N_READY_CHARS): New macro: Returns number of unread
2734 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2735 (struct scm_port_table): New fields: `entry' contains port table
2736 index, `cp' points to last unread char, `cbuf' is the buffer for
2737 unread chars, `cbufend' points after end of the character buffer.
2739 * ports.h, ports.c (scm_unread_string): New procedure.
2740 (scm_grow_port_cbuf): New function.
2742 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2744 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2745 to read unread characters. Use SCM_TRY_CLRDY instead of
2748 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2750 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2752 * genio.c, genio.h (scm_ungets): New function.
2754 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2757 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2759 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2760 declarations. (Thanks to Russ McManus.)
2762 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2764 * numbers.c (num2long): As a software archeologist, I'm proud of
2765 this finding! :) Preliminary dating suggests an almost 4 year old
2766 remnant from the SCM ancestor. The sample has been removed from
2767 the finding site and is now safely stored in the repository.
2769 * numbers.h: Removed prototype for num2long.
2771 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2773 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2774 array as second arg.
2775 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2776 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2777 * gh.h: Updated and added prototypes.
2779 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2781 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2783 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2785 * guile-snarf.in: Never generate an empty file. (Thanks to
2788 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2789 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2790 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2791 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2792 gh_new_procedure5_0): Specify argument types, to appease C++
2793 compilers. (Thanks to Brad Bowman.)
2795 Bug reports from Russ McManus:
2796 * guile-snarf.in: If the CPP environment variable is set, use that
2797 as the C preprocessor, instead of the preprocessor autoconf
2799 * snarf.h (SCM_PROC): Cast the function pointer passed to
2800 scm_make_gsubr, to satisfy C++.
2802 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2803 Use the handler passed, instead of ignoring it and using
2804 gh_standard_handler. (Thanks to Etienne Bernard.)
2806 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2808 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2811 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

2828 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2831 * script.c (scm_compile_shell_switches): Define
2832 use-emacs-interface in the root module, so the repl code can see
2833 it. See today's change to top-repl in ice-9/boot-9.scm.
2835 * filesys.c (set_element, get_element): Make sure that `element'
2836 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2837 Boekemeier and Jorgen "forcer" Schaefer.)
2839 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2841 * chars.c (scm_charnames): In ASCII character name table, make
2842 newlines print as #\newline by default, not #\nl.
2844 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2845 alphabetical order. Oh thrills. But it helps me know how far
2846 along in the compilation I am.
2847 * Makefile.in: Regenerated.
2849 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2851 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2852 #bytes(...) to #y(...), and syntax for short vectors from
2853 #short(...) to #h(...). This may seem nutty, but, like the other
2854 uniform vectors, byte vectors and short vectors want to have the
2855 same print and read syntax (and, more basic, want to have read
2856 syntax!). Changing the read syntax to use multiple characters
2857 after the hash sign breaks with the conventions used in R5RS and
2858 the conventions used for the other uniform vectors. It also
2859 introduces complexity in the current reader, both on the C and
2860 Scheme levels. (The Right solution is probably to change the
2861 syntax and prototypes for uniform vectors entirely.)
2863 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2865 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2866 (Thanks to Jorgen "forcer" Schaefer.)
2867 * ports.h (SCM_NOFTELL): New flag.
2868 * fports.c (local_fgets): If it's set, use the generic fgets.
2869 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2871 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2873 * script.c (scm_compile_shell_switches): Add handling of -q switch
2874 (inhibit loading of user init file).
2875 (scm_shell_usage): Add usage text for -q switch.
2876 (scm_compile_shell_switches): Always load user init file first if
2877 it is loaded at all.
2879 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2881 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2882 and is now broken under NetBSD. I can't fathom what it's trying
2883 to do, so I've replaced it with something that I do understand,
2884 which seems to work, and which isn't broken on NetBSD. "Progress?
2885 You Decide." (Thanks to Perry Metzger.)
2887 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2888 signed/unsigned comparison.
2890 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2892 Warning fixes from Greg Harvey:
2893 * unif.c (scm_array_set_x): initializer for pos
2894 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2895 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2896 initializers for field_type, since EGCS so desparately wants to
2898 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2899 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2900 when GUILE_DEBUG is defined.
2901 * dynwind.h (scm_wind_chain): Same.
2902 * ports.h (scm_pt_size, scm_pt_member): Same.
2903 * print.h (scm_current_pstate): Same.
2904 * procs.h (scm_make_cclo): Same.
2906 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2908 Handle short and long long uniform arrays properly. (Thanks to
2910 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2911 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2912 scm_tc7_llvect (long long vectors).
2914 Change the way libguile and boot-9.scm are timestamped, to try to
2915 get rid of these spurious mismatch warnings. Now both
2916 libguile/versiondat.h and ice-9/version.scm are generated directly
2917 by the configuration process, rather than having version.scm
2918 generated directly, and libguile/versiondat.h generated by the
2919 Makefile, which is generated by configure. It seems that
2920 sometimes the Makefile would change, but versiondat.h depends on
2921 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2922 * Makefile.am (versiondat.h): Target removed; this is generated
2923 directly by the configure script now.
2924 (BUILT_SOURCES): Remove versiondat.h.
2925 * versiondat.h.in: New file, transformed by the configure script
2927 * Makefile.in: Regenerated.
2929 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2930 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2931 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2932 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2933 if we want to use them in a header file some day, we can. (Thanks
2934 to Michael Livshin.)
2936 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2937 SCM numbers, so we won't have rollover problems; the range of a
2938 signed long in milliseconds is about 25 days. (Thanks to Karl
2941 Don't redefine sleep and usleep; fix this problem now.
2942 * coop.c (sleep, usleep): Remove declarations; we don't use or
2943 redefine these any more.
2944 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2945 job of usleep and sleep in a thread-friendly way. We can use
2946 these in the rest of Guile. Define versions for systems both with
2947 and without iselect.
2948 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2949 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2950 we're just using it, not redefining it, we can use a K&R style
2952 (sleep): Declare this, too, if the system hasn't.
2953 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2954 scm_uthread_sleep if they're available; otherwise, just call the
2956 * scmconfig.h.in: Regenerated.
2958 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2960 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2962 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2964 * threads.c: Doc fix.
2966 The argument type of usleep varies from system to system,
2967 as does the return type. We really shouldn't be redefining usleep
2968 at all, but I don't have time to clean that up before the 1.3.
2969 release. It's on the schedule for afterwards. (Thanks to Julian
2971 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2973 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2974 * scmconfig.h: Regenerated.
2976 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2977 right way to handle system variation. Autoconf's approach is the
2979 * simpos.h (scm_software_type): Declaration deleted.
2981 * script.c (scm_find_executable): Don't test if unix is #defined
2982 here; first, NetBSD doesn't #define it, and second, it's the wrong
2983 way to go about these things. (Thanks to Perry Metzger.)
2984 (dld_find_executable): Delete this MSDOS support code. This isn't
2985 the way we want to support this; it needs to be rethunk at a
2988 * genio.c (scm_do_read_line): Don't just politely check that the
2989 line was either non-empty or EOF. Abort if it's empty and not
2992 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2994 * scmconfig.h.in: Regenerated.
2996 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2999 * genio.c (scm_do_read_line): Count lines correctly when the file
3000 doesn't end in a newline.
3002 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
3004 * genio.c (scm_do_read_line): Maintain the line count correctly.
3005 (Thanks to Harvey J. Stein and Greg Harvey.)
3007 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
3010 * numbers.c (big2str): Protect t from garbage collection until
3011 we're done. (Thanks to Gary Houston.)
3013 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
3015 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
3017 * Makefile.in: Regenerated.
3019 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
3020 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
3023 Do magic to mix reads and writes on stdio FILE-based ports.
3024 (Thanks to Christian Lynbech.)
3025 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
3027 (pre_read, pre_write): New functions.
3028 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
3029 local_fputs): Call them.
3030 (local_fflush): Mark the port as ready for reading and writing.
3031 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
3032 flags on new port objects. This might not be accurate --- who
3033 knows what state the FILE * is in when we get it --- but it won't
3034 do extraneous calls to fflush or fseek, so it's no worse than the
3035 behavior before this change.
3036 * ports.h: Add comment.
3038 Centralize the creation of port objects based on stdio FILE * in
3039 fports.c; don't just throw them together anywhere.
3040 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
3041 what the rest of Guile wants. Don't set the revealed count;
3042 that's only appropriate for stdin, stdout, stderr.
3043 (scm_standard_stream_to_port): This function does set the revealed
3045 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
3046 not scm_stdio_to_port.
3047 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
3048 * fports.c (scm_open_file): Same.
3049 * posix.c (scm_pipe): Same.
3050 * socket.c (scm_sock_fd_to_port): Same.
3051 * ioext.c (scm_fdopen): Same.
3052 (scm_freopen): Moved from here to...
3053 * fports.c (scm_freopen): ... here. This is really something that
3054 munges the internals of an fport, so it should go here.
3055 * fports.h (scm_stdio_to_port): Adjust prototype.
3056 (scm_standard_stream_to_port, scm_freopen): New protoypes.
3057 * ioext.h (scm_freopen): Prototype removed.
3059 * filesys.c (set_element, get_element): This can work on both pipe
3060 and file ports, so use SCM_FPORTP to typecheck, instead of testing
3063 * scmconfig.h.in: Regenerated.
3065 Change the definition of the functions in scm_ptobfuns so that
3066 they get passed the port object, not the port's stream.
3067 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
3068 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
3069 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
3070 Pass the port itself to the scm_ptobs function.
3071 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
3072 scm_generic_fgets): Same.
3073 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
3074 getc_void_port, fgets_void_port, close_void_port): Just change the
3075 argument names; these functions don't really do anything.
3076 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
3077 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
3078 port as an argument, and use SCM_STREAM to get the stdio FILE *.
3079 Also, use prototyped definitions, and get rid of the extra
3081 (scm_fptob, scm_pipob): We don't need casts here any more.
3082 * strports.c (prinstpt): Use prototype declarations.
3083 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
3084 and use SCM_STREAM to get the string info. Also, use prototyped
3085 definitions, and get rid of the extra declarations.
3086 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
3089 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
3090 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
3092 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
3093 scm_fgets, for consistency.
3094 (scm_fptop, scm_pipob): References updated.
3096 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
3098 Include the source location in error messages for scripts.
3099 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
3100 stack is still there when we catch the error.
3101 * throw.c (handler_message): If we are handling an error with a
3102 message, then put together the proper arguments and call
3103 scm_display_error, instead of scm_display_error_message. That
3104 displays source location, if it can find it.
3106 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
3108 * gc.c (scm_unprotect_object): Change this so that calls to
3109 scm_protect_object and scm_unprotect_object nest properly.
3110 (scm_protect_object): Doc fixes.
3112 * strings.c (scm_string_set_x): Require the argument to be a
3113 writable string, not a substring or a symbol.
3114 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
3115 (Thanks to John Redford and Charbel Jacquin.)
3117 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
3119 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
3121 * eval.c (safe_setjmp): Remove this misunderstanding.
3122 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
3125 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
3127 * libguile.h: Mark these as C declarations, for compilation by C++
3130 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
3131 __cplusplus clause. I seriously doubt this ever worked the way
3132 the author seems to have intended.
3134 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
3136 Utterly needless cleanups to hopelessly messy code.
3137 * ports.c: Doc fixes.
3138 (scm_fflush): Moved to ...
3139 * genio.c (scm_fflush): ... here, amongst all the other port
3140 method invocation functions.
3141 * genio.h, ports.h: The prototype moves too.
3143 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
3145 * backtrace.c (display_error_body): The current frame does not
3146 always have a parent frame; consider a function called directly
3147 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
3150 * alloca.c (alloca): Undo yesterday's changes, and simply call
3151 malloc directly for storage, and abort if we don't get what we
3152 want. The situation is much simpler --- just call malloc. Emacs
3153 has bizarre/evil requirements (signal handlers might malloc unless
3154 you set this global flag, so you have to set the flag around all
3155 calls to malloc) which we are certainly not going to conform to,
3156 so we can do the simple and obvious thing.
3158 * coop.c (coop_condition_variable_wait): Make this function
3159 static. It's only useful internally --- you should never just
3160 wait on a condition variable.
3161 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
3163 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3165 * unif.c (scm_array_set_x): Accept any kind of number as an
3166 element for a uniform vector of doubles. This is more consistent
3167 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
3169 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
3170 works; I can't conveniently test it myself. (Thanks to Dvid
3171 Tillman for the bug report.)
3173 * init.c: Doc fixes.
3175 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
3176 from here, not from scm_compile_shell_switches (which is a pretty
3177 dumb place to do it).
3178 (scm_load_startup_files): New function.
3179 (scm_ice_9_already_loaded): Variable moved to here from script.c.
3180 * script.c (scm_compile_shell_switches): Don't load the startup
3182 (scm_ice_9_already_loaded): Variable moved.
3183 * init.c (scm_load_startup_files): Prototype for new function.
3184 * gh_init.c (gh_enter): Doc fix.
3186 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3188 Some anti-warning changes from Greg Harvey.
3189 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
3190 warnings when it doesn't understand our NORETURN declarations in
3192 * posix.c (scm_mknod): Similar.
3194 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3196 * posix.c (scm_getpwuid): If we can't find an entry, return our
3197 own message, instead of using scm_syserror --- the getpwMUMBLE
3198 functions don't set `errno' to anything interesting.
3200 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3202 Get rid of warnings from the cooperative threading system.
3203 * threads.h (scm_single_thread_p, scm_yield,
3204 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
3205 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
3206 scm_wait_condition_variable, scm_signal_condition_variable): Add
3207 prototypes for these Scheme-visible functions.
3208 * coop-defs.h (coop_next_runnable_thread,
3209 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
3210 Prototypes for these here, even though they're from iselect.c.
3211 (coop_condition_variable_wait, coop_join): Add prototypes.
3212 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
3213 scm_threads_free_condvar): Make these smob functions static.
3214 * coop-threads.h (coop_init): Give this a real prototype.
3215 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
3216 (coop_next_runnable_thread): No need to provide prototype; it's in
3219 * scmconfig.h.in: .detarenegeR
3221 * iselect.c, threads.c: Doc fixes.
3223 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3225 * Makefile.in: Regenerated with a patched automake, to get
3226 dependency generation right when using EGCS.
3228 * inet_aton.c (inet_aton): Add prototype, to remove compiler
3229 warning. (Thanks to Robert Pluim.)
3231 * inet_aton.c (inet_aton): Reassure the compiler that the
3232 arguments to the <ctype.h> macros are all unsigned characters, not
3235 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3237 Getting rid of more warnings...
3238 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
3239 today's change to ../configure.in.
3240 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
3241 * scmconfig.h.in: Regenertaded.de.,.__
3242 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
3243 (scm_localtime, scm_mktime): Use a const char * to manipulate the
3246 * readline.c: Doc fix.
3247 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
3248 * readline.h (scm_filename_completion_function): Add prototype.
3249 (scm_init_readline): Make this into a prototype.
3251 * readline.c (scm_filename_completion_function): Use SCM_PROC to
3252 declare this, instead of calling scm_make_subr manually.
3254 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
3256 * readline.h (scm_init_readline): Add prototype for this.
3257 (scm_init_readline): Make this a real prototype.
3259 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3261 Warning fixes from Maciej Stachowiak:
3262 * backtrace.h (scm_display_application, scm_backtrace): Add
3264 * debug.c (scm_m_start_stack): Make this function static.
3265 * fluids.h (scm_fluid_p): Add prototype.
3266 * procprop.c (scm_i_procedure_arity): Make this function static.
3267 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3268 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
3269 * root.h (scm_dynamic_root): Add external prototype.
3270 * scmsigs.h (scm_usleep): Add external prototype.
3271 * script.h (scm_init_script): Use prototype, not K&R decl.
3272 * stacks.h (scm_stack_id): Add external prototype.
3273 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3275 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3277 * gh.h: took out the definitions of vset and vref, since they are
3278 replaced by the proper vector routines that correspond to the R4RS
3281 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3283 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3284 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3285 third argument, a C expression that should result in a SCM value,
3286 which is used to initialize the variable. Reimplemented
3287 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3290 * version.h (scm_libguile_config_stamp): Add prototype.
3291 (From Maciej Stachowiak.)
3293 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3295 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3296 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3298 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3300 * print.c (scm_iprin1): Rather than having one i, and using it in
3301 several places, declare a fresh i local to each block where it is
3302 used, and give it a signedness appropriate to its use in each case.
3303 (scm_iprlist): Same.
3305 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3306 comparison warnings.
3308 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3309 signed/unsigned clashes.
3311 * posix.h (scm_tmpnam): Added prototype.
3313 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3314 scm_make_subclass_object): Add external prototypes.
3316 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3317 comparison is okay here.
3319 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3321 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3322 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3324 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3327 * load.c (swap_port): Make this function static.
3329 * load.c (scm_search_path): Make max_path_len and max_ext_len
3330 unsigned, since they're compared against string sizes.
3332 * load.c (init_build_info): Make i unsigned.
3334 * ioext.h (scm_read_line): Add prototype.
3336 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3337 scm_hash_fn_remove_x): Make hash bucket index local variable k
3338 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3339 accurately as possible.
3341 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3342 comparisons, and range checking to make sure those casts are
3345 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3346 signed/unsigned comparisons.
3348 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3349 avoid signed/unsigned comparisons.
3350 * smob.h (scm_numsmob): Change extern declaration to match.
3352 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3353 avoid signed/unsigned comparisons.
3354 * ports.h (scm_numptob): Change extern declaration to match.
3355 (scm_current_load_port, scm_set_port_line_x,
3356 scm_set_port_column_x): New prototypes.
3358 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3359 test code, and it causes warnings.
3361 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3362 gh_uniform_vector_ref): Added prototypes.
3364 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3365 debugging support unconditionally. That's backtrace.c, stack.c,
3366 debug.c, and srcprop.c.
3367 (EXTRA_libguile_la_SOURCES): Omit those from here.
3368 * Makefile.in: Regenerated.
3370 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3372 * options.c (scm_options): Bugfix: Allow empty list of options!
3374 * debug.c, debug.h (scm_single_step): Removed.
3375 (scm_with_traps): New procedure. This procedure could easily be
3376 written in Scheme but needs to be highly optimized.
3378 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3380 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3381 Check SCM_TRAPS_P before trapping.
3383 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3385 Changes to avoid signed/unsigned comparison warnings.
3386 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3387 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3388 so they can have appropriate types for each application. Make i
3389 signed. Use initializers in some spots. I'll probably pay for
3391 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3392 (scm_must_realloc): Make nm unsigned.
3393 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3394 (scm_init_storage): Use prototype-style definition, and make the
3396 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3397 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3399 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3400 avoid signed/unsigned comparison warnings, and because the return
3401 value of readlink may be -1. Don't bother casting the third
3402 argument to readlink.
3404 * filesys.c (scm_dirname, scm_basename): Move these to their own
3405 page, at the end of the file.
3406 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3408 * eval.h (scm_eval_options_interface): Add external prototype for this.
3409 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3411 * eval.c (scm_lookupcar1): Make this static.
3413 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3414 Make these prototype declarations, not K&R-style.
3416 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3417 unsigned comparison warning.
3419 * appinit.c: File removed. It had a single function in it, empty,
3420 whose reason for existence is explained in no documentation or
3421 comment. I think it's there as a default for some Tcl-style
3422 initialization, but Tcl abandoned that approach a while ago.
3423 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3424 (BUILT_SOURCES): Remove appinit.x.
3425 * Makefile.in: Regenerated.
3427 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3429 * Makefile.in: Regenerated using the last public version of
3430 automake, not the hacked Cygnus version.
3432 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3434 Remove Totoro kludge.
3435 * Makefile.in, scmconfig.h.in: Regenerated.
3436 * init.c, readline.c: Don't check if TOTORO is #defined.
3438 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3440 * Makefile.am: Adjust for new thread configuration system.
3441 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3442 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3444 (THREAD_LIBS): Definition deleted; automake will generate such
3445 things automatically.
3446 * Makefile.in: Regenerated.
3448 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3450 Simplify smob and port marking; set the mark bit in the generic
3451 marking code, and make marker routines only responsible for
3452 turning up outgoing pointers.
3453 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3454 before calling the marking function. Don't call the marking
3455 function if it's zero.
3456 * markers.c (scm_mark0): Just return #f. This function isn't
3457 necessary at all now, but it's harmless to call it. We'll leave
3458 it in so other folks' code doesn't croak at link time.
3459 (scm_markcdr): Don't call SCM_SETGC8MARK.
3460 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3461 * dynl.c (mark_dynl_obj): Same.
3462 * root.c (mark_root): Same.
3463 * srcprop.c (marksrcprops): Same.
3464 * unif.c (markra): Same.
3465 * variable.c (scm_markvar): Same.
3466 * ports.c (scm_markstream): Same.
3467 (void_port_ptob): Specify zero for our marking function.
3468 * debug.c (debugobjsmob): Same.
3469 * dynwind.c (guardsmob): Same.
3470 * filesys.c (dir_smob): Same.
3471 * fluids.c (fluid_smob): Same.
3472 * fports.c (scm_fptob, scm_pipob): Same.
3473 * mallocs.c (mallocsmob): Same.
3474 * regex-posix.c (regex_t_smob): Same.
3475 * smob.c (freecell, flob, bigob): Same.
3476 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3477 * throw.c (jbsmob, lazy_catch_funs): Same.
3479 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3481 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3482 scm_copy_tree on code in order not to let memoized code to leak
3483 out. Thus, scm_copy_tree needs to copy vectors as well since
3484 quasiquote can introduce evaluated code also inside vector
3487 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3489 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3491 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3492 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3495 * unif.c: Say that ivect and uvect are of type signed and unsigned
3496 long instead of int in commentary so that it correctly describes
3499 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3501 * stime.c: Removed declaration of strptime. (It should be
3502 declared by the system headers. If it turns out that some systems
3503 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3505 * stime.h: Renamed TIMEH --> STIMEH
3507 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3508 to increase portability, don't use structure assignment.
3509 (Thanks to Nicolas Neuss.)
3511 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3513 (finalize_fd_sets): Added empty statement after last case label.
3514 (Thanks to Nicolas Neuss.)
3516 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3519 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3521 * init.c, readline.c: OK, I won't have these readline.x bug
3522 reports anymore. We've had them since April. The current reason
3523 is a completely unintelligible failure of totoro.red-bean.com to
3524 do the test for rl_getc_function in libreadline correctly. This
3525 kludge overrides the test if we're on totoro so that the snapshot
3526 generation process can work.
3528 * readline.c: Define a strdup replacement if not existent on system.
3530 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3532 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3533 This change makes scm_make_vector R5RS compatible. We cannot keep
3534 the third argument since people want to be able to deduce the form
3535 of the C function call only by looking at R5RS. (At the same time
3536 we have removed some unnecessary complexity!)
3538 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3539 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3540 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3541 argument in call to scm_make_vector.
3543 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3545 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3546 This macro is useful in applications.
3548 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3550 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3551 (scm_parse_path, scm_search_path): New Scheme level procedures.
3553 * load.h (scm_internal_parse_path, scm_parse_path,
3554 scm_search_path): Declared.
3556 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3558 * filesys.c (dirname, basename): New procedures.
3560 * init.c (scm_boot_guile_1): Removed condition around
3563 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3564 new data type (guards) for representation of C level guards and
3565 data on the wind chain.
3566 (scm_internal_dynamic_wind): New function.
3568 * dynwind.h: Declare scm_internal_dynamic_wind.
3570 * root.h (scm_root_state): Added scm_cur_loadp.
3572 * root.c (mark_root): Added comment about cur_loadp.
3574 * load.c: #include "dynwind.h";

3578 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3580 * ports.c (current-load-port): New procedure.
3582 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3584 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3585 not a tty, return #f.
3587 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3588 to Julian Satchell and Roland Kaufmann.)
3590 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3591 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3593 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3595 * debug.h, debug.c (scm_start_stack): New function. Implements
3596 the guts of old scm_m_start_stack.
3598 * debug.c (scm_m_start_stack): Use scm_start_stack.
3600 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3601 start_stack and restart_stack. (These have static scope.)
3603 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3605 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3606 readline functions to come in release 2.3. (Thanks to Chet
3608 (handle_errors): Use the above functions.
3610 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3612 * readline.c: Improvements for readline support: Handle errors
3613 better; Implement before-read-hook.
3615 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3617 * init.c (scm_boot_guile_1), readline.c: Test for
3618 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3619 assure that we have version >= 2.1.)
3621 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3623 * readline.c (scm_readline): Defer interrupts while we're calling
3626 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3627 away the string to add_history.
3628 (completion_function): Do completion for readline. (Thanks to
3630 (scm_filename_completion_function): New procedure: Filename
3632 (current_input_getc): New function. Use this one instead of
3633 standard getc from readline.
3635 * throw.c, throw.h (scm_handle_by_throw): New function: This
3636 handler throws errors to next handler on the dynwind chain.
3638 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3640 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3643 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3645 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3647 (scm_procedure_properties): Modified to return arity together with
3649 (scm_procedure_property): Added the read-only property `arity'.
3650 (scm_set_procedure_property_x): It is an error to set the `arity'
3653 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3654 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3656 * procprop.h (scm_sym_arity): New symbol.
3658 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3659 to set the dispatch procedure of an operator or entity object.
3661 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3662 Made procedure slots read-only.
3664 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3665 scm_tcs_cons_gloc case in zero args switch; Fixed args
3666 construction for operators in scm_tcs_cons_gloc case in two args
3669 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3671 * fluids.c: Removed use of assert.h (in order to avoid
3674 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3676 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3678 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3679 change makes the evaluator safer at the cost of evaluation speed.
3680 It handles the case when the user has added a non-immediate
3681 improper end of the application form, e.g., `(+ 0 . x)'.
3682 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3683 minimize the extra cost as much as possible. The new code is
3684 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3685 problem with structs planted directly in the code (e.g. by a
3686 macro). This no longer causes segmentation fault. (Thanks to
3689 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3690 arg `proc' in order to be able to throw errors; New argument
3693 * Removed extra #include "debug.h"
3695 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3697 * scmsigs.c: Declare usleep as returning void on some systems.
3698 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3701 * coop.c (usleep): Return void on some systems.
3703 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3705 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3707 * coop.c: Changed return type of usleep to int.
3709 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3710 isn't found in the OS.
3712 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3713 isn't enabled. (Thought that I had made this change ages ago...)
3715 * iselect.c: Declare bzero if not defined by OS.
3717 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3719 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3720 condition. (Thanks to John Tobey.)
3722 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3723 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3726 * __scm.h: Start the long-term project of moving to POSIX threads.
3727 Phase 1: Classification of all critical sections.
3728 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3729 for A sections. (See comments in __scm.h for details.)
3731 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3732 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3734 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3736 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3737 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3738 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3739 dependencies on $(srcdir)/Makefile.in
3740 $(top_builddir)/config.status in order to avoid circularity.
3742 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3743 from argc if argc was 0 initially.
3745 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3746 in generation of libpath.h.
3748 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3750 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3751 libguile from 2 to 3.
3753 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3755 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3757 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3759 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3760 scm_set_port_column_x, scm_port_filename,
3761 scm_set_port_filename_x): Removed optional arguments. Added
3762 proper argument checking.
3764 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3765 stack size in machine words.
3767 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3768 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3769 to Ole Myren Röhne.)
3771 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3773 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3774 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3776 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3779 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3780 procedure apply: Copy argument lists before pushing them unto the
3781 environment so that the environment won't get mutated due to
3782 manipulation of procedure arguments. This should perhaps be
3783 regarded as a temporary solution until someone finds a more
3784 efficient one. (Thanks to Maciej Stachowiak.)
3786 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3788 * script.c (scm_compile_shell_switches): Use "guile" as default
3789 zero arg if argc is NULL.
3791 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3793 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3794 is zero. (Thanks to Dirk Herrmann.)
3796 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3798 * ports.c (scm_add_to_port_table): First line is now line 0
3799 (was 1). (Interface changed according to suggestion by Per
3802 * backtrace.c (display_header): Add 1 to line and column numbers
3803 when presenting them to the user.
3805 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3806 from debug.c --> eval.c
3808 * eval.h, eval.c (scm_eval_options_interface): New options
3810 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3811 i.e. stacks for new threads.
3813 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3815 * eval.c (unsafe_setjmp): Removed with #if 0.
3817 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3820 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3821 to avoid compiler warnings.
3823 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3825 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3827 * throw.c (handler_message): Print message on current error port
3828 instead of default error port. (Thanks to Maciej Stachowiak.)
3830 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3832 * ports.c (scm_add_to_port_table): allocate in units of
3833 struct scm_port_table *, not struct scm_port_table.
3834 * posix.c (scm_close_pipe): remove the port from the port table
3836 Thanks to Rob Engle for both fixes.
3838 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3840 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3841 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3843 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3845 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3847 * backtrace.c (display_error_body, display_backtrace_body),
3848 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3849 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3850 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3851 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3854 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3855 don't receive the jmpbuf arg anylonger.
3856 (scm_catch): Don't accept a #f tag.
3857 (scm_throw): Check that key is a symbol.
3858 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3860 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3862 * async.c (async_pending): Removed declaration.
3864 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3866 * dynwind.c (scm_wind_chain): New debug function.
3868 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3869 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3870 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3871 extra layer of functions around the body and handler of a thread.
3872 This extra layer makes sure that the handler is called in the
3873 dynamic context of the surround (= empty dynwind list), but under
3874 the *dynamic root* of the body. We can not use the dynamic root
3875 of the surround since that root belongs to another thread => stack
3876 is not handled correctly. It may seem ugly to use this extra
3877 layer, but the extra cost in terms of execution time is really
3878 negligible compared to the total amount of time required to create
3879 a thread, and it would reduce maintainability to duplicate the
3880 crucial and complicated steps performed by cwdr.
3882 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3883 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3884 get re-enabled. The important effect of this is that interrupts
3885 are blocked during thread switching so that thread data structures
3886 don't risk getting messed up by an unfortunate signal.
3887 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3888 seems to do more aggressive optimization which actually move
3889 instructions around in these macros in a fatal way. Therefore:
3890 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3891 just superstitious...)
3892 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3893 This macro should be used instead of SCM_ASYNC_TICK since the
3894 latter doesn't do context switches any more.
3896 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3897 instead of SCM_ASYNC_TICK.
3899 * coop.c, iselect.c: Since thread switches are now performed with
3900 interrupts masked, we can't use the old mechanism of delivering
3901 signals immediately when they arrive. Signals must instead be
3902 delivered when the asyncs run *after* the end of the critical
3903 section in scm_internal_select. But this also means after context
3904 switch so that the signal will be delivered to a different thread.
3905 To avoid this, I have changed the protocol of
3906 coop_wait_for_runnable_thread and friends so that they are allowed
3907 to return the original thread. So, if a signal arrives during
3908 scm_internal_select, we won't any longer be forced do a context
3909 switch, but can remain in the same thread and deliver the signal
3912 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3913 scm_asyncs_pending and made it global.
3915 * iselect.c: Small fixes.
3917 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3918 coop_condition_variable_init, coop_condition_variable_wait,
3919 coop_condition_variable_signal): Changed return type from `void'
3920 to `int'. This is to adhere closer to the pthreads interface.
3921 This, in turn, is part of an attempt to provide C versions of the
3922 mutex and condition variable primitives which can be part of a
3923 frontend to COOP or pthreads.
3925 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3926 coop_condition_variable_destroy): New functions.
3928 * coop-threads.c (scm_wait_condition_variable): Use
3929 coop_condition_variable_wait_mutex.
3931 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3932 Definitions moved to coop-defs.h.
3934 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3935 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3936 scm_cond_destroy): New C interface to mutecis and cond vars.
3938 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3940 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3942 * iselect.c: Now several threads can wait on the same file
3943 descriptor. The behaviour is compatible with OS select: All
3944 threads waiting for the fd return with the same status.
3946 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3948 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3949 Can spawn a thread from application C code.
3951 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3953 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3954 gh_doubles2scm): New functions.
3956 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3958 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3959 commented-out version of gh_eval_str()
3961 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3963 * socket.c (scm_bind): free soka after use.
3965 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3967 * stime.c (tzvar): new variable.
3968 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3969 avoid memory leaks when allocating.
3971 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3973 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3976 * gc.c, tags.h: Doc fixes.
3978 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3980 * eval.c (macro-eval!): Removed. This function was a design bug.
3981 It allowed memoized code to leak out to the scheme level. Most
3982 things that you could do with `macro-eval!' can be done with
3985 1997-12-20 Tim Pierce <twp@skepsis.com>
3987 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3988 scm_fgets now depends on ftell(3) to know how many bytes were
3991 1997-12-15 Tim Pierce <twp@skepsis.com>
3993 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3994 dealing with strings.
3996 1997-12-13 Tim Pierce <twp@skepsis.com>
3998 Make %read-line more suitable for implementing read-line efficiently.
3999 * ioext.c (scm_read_line): Strip the terminating newline from a
4000 string, and return a cons of the string and its terminator.
4002 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
4003 of the string that is read is stored in this memory location.
4004 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
4005 * genio.c, genio.h (scm_do_read_line): Update caller.
4006 * ports.h (scm_ptobfuns): Update typedef.
4007 * fports.c (scm_fptob, scm_pipob): Update struct.
4009 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4011 * filesys.c (set_element): Return file descriptor.
4012 (fill_select_type): Return the highest file descriptor.
4013 (scm_select): Tell select about the highest file descriptor. On
4014 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
4015 Therefore the extra overhead for calculating the maximum fd seems
4016 to be more than compensated. Is this correct? In any case,
4017 scm_internal_select will be much faster with this info.
4018 (scm_select, fill_select_type, set_element): Don't accept any kind
4019 of object in the file descriptor list or vector.
4021 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4023 * iselect.c (finalize_fd_sets): Bugfix.
4025 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4027 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
4028 when using scm_internal_select (since we might switch to another
4031 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
4033 * simpos.c (scm_system): always define: use sysmissing if not
4034 available. Check for HAVE_SYSTEM instead of _Windows (does
4035 Windows lack system or does it have an unusable one?).
4036 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
4037 Let the argument be optional: if not supplied, call system(NULL).
4039 * ports.c (scm_close_port): relax the type check from OPPORTP to
4040 PORTP; closing a closed port is allowed.
4042 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
4044 * fports.c (scm_fgets): Return if the last char in a chunk is
4045 newline. When fgets returns a string whose length is `size-1', it
4046 is ambiguous whether a whole line was retrieved, so we must check
4047 explicitly whether a line terminator is present.
4049 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4051 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
4052 before taking the CDR. (Thanks to Harald Meland.)

4132 replacement in iselect.c.
4133 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
4134 coop_join): If GUILE_ISELECT enabled, use
4135 coop_wait_for_runnable_thread instead of
4136 coop_next_runnable_thread.
4137 (usleep, sleep): New replacements for system functions if
4138 GUILE_ISELECT is enabled.
4140 * coop-threads.h: Declare coop_wait_for_runnable_thread.
4142 * coop-defs.h (coop_t): Added fields used by scm_internal_select.

4157 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
4158 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
4159 and scm_must_free, since ultimately the string returned will be copied
4160 by scm_makfrom0str anyway. Also, read any characters that may have
4161 been pushed onto the port with scm_ungetc.
4162 * ports.c (scm_generic_fgets): Same as for scm_fgets.
4163 * ioext.c (scm_read_line): Free string after Guilifying it.

4179 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
4180 and to invoke scm_shell().
4181 (gh_launch_pad): took out the loading of boot-9.scm from here,
4182 since it is probably best to let the user control that. In fact,
4183 gh_repl() now invokes scm_shell() which does that.
4185 1997-11-23 Mark Galassi <rosalia@cygnus.com>
4187 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

4212 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
4214 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when

4222 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
4224 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
4225 OPORT is an `open' port, not an output port.

4234 scm_close_all_ports_except, scm_set_current_output_port,
4235 scm_set_current_error_port): Likewise
4236 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
4237 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):

4251 exactly what we want to leave in to detect substrings.
4252 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
4253 * tags.h: Fix diagrams and comments describing the S tag bit;
4254 remove vestigial remarks about the D tag bit.

4277 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4279 * gh_data.c (gh_vector_set_x): changed name to make it consistent

4308 * tags.h (scm_tc7_substring): Changed the comment and code to
4309 conform with the changes below. Folks! We have suddenly two new

4374 * gh_test_c.c (c_vector_test): some improvements on the vector
4377 * gh.h (gh_vector): this used to exist but do the wrong thing.
4378 Now it (almost) does the right thing, though it takes a list
4379 instead of the individual arguments. I need to see how it could
4381 (gh_list_to_vector): added this function as a macro. Corresponds
4382 to Scheme's (list->vector ...).

4390 (gh_make_vector): this used to be (stupidly) called gh_vector().
4391 This is the right name, since it does the same thing as the Scheme

4441 transformers. (They are always: exp env.); Bugfix: Unmemoize
4442 transformer source with correct environment.

4452 (scm_internal_cwdr): New function to perform the function of cwdr
4453 but take args that are more useful to C code. Also, the handler
4454 is now invoked *outside* of the new dynamic root, like the docs

4456 is responsible for using a handler that does not throw, if he
4458 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4459 * root.h (scm_internal_cwdr): New prototype.
4461 Even more but risky streamlining:
4463 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4464 allocation of the jumpbuf of a root continuation. The changes
4465 below are controlled by it. They are now deactivated.
4466 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4467 the JMPBUF of the scm_rootcont to NULL before returning.
4469 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4470 when they are non-NULL.

4492 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4493 Accept a port/print-state pair in addition to just a port.
4494 (scm_prin1): Don't return the print_state to the pool when it has
4496 (scm_printer_apply): Set `revealed' field of print_state to true.
4497 (scm_init_print): Set scm_print_state_vtable.

4514 * strports.c (scm_eval_string): Don't close the port.
4516 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4517 former returns a nice normal integer. (Thanks to Daniel
4520 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4522 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4523 makefile variable as a build parameter called LIBS. The
4524 build-guile program will use this, for the time being.
4525 * Makefile.in: Regenerated.
4527 Thanks to Shiro Kawai:
4528 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4529 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4532 * Makefile.in: Regenerated with automake 1.2a.
4534 * script.c (scm_compile_shell_switches): If we hit the -c or --
4535 arguments, don't set the car of (command-line) to scm_usage_name,
4536 the prettified name of the guile executable; give it the full
4537 path, the way shells usually handle $0.
4539 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4541 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4542 Scheme-level name `array-map' and renamed `serial-array-map' to
4543 `serial-array-map!'.
4545 * backtrace.c: Introduced exception handlers which now enclose
4546 `display-error' and `display-backtrace' so that error reporting
4547 won't get into infinite loops if an error occurs during displaying
4548 of the error. This can very easily happen with user supplied
4549 print call-back routines.
4551 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4553 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4554 the names `serial-array-map' and `array-map' should be removed.)
4556 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4558 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4559 Added #include "objects.h"
4561 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4562 Add #include "feature.h".
4564 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4565 (modinclude_HEADERS): Added objects.h.
4567 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4568 This test is needed at many places in the code and should be
4569 abstracted. (Motivated by the need of this test in libguiletk.)
4571 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4572 (scm_eval_string), load.c (scm_primitive_load,
4573 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4574 Use SCM_EOF_OBJECT_P.
4576 * eval.c (scm_init_eval): Add feature `delay'.
4578 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4580 * scmhob.h: Removed.
4582 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4584 * list.h (SCM_LISTn): New macros. Make list creation in C code
4585 prettier. The idea comes from STk.
4587 * sequences.h, sequences.c, append.h, append.c: Removed. These
4588 files implemented non-R4RS operations which would encourage
4589 non-portable programming style and less easy-to-read code.
4591 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4594 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4595 sequences.h, #include append.h.
4597 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4600 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4602 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4604 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4606 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4608 * eval.c: Added #include "objects.h"
4610 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4613 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4614 adjacent smob numbers.
4616 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4618 * procprop.h: Added declaration of scm_i_inner_name.
4620 * gsubr.c: New global symbol scm_i_inner_name.
4622 * debug.c (scm_procedure_name): Try procedure property
4623 `inner-name' if `name' fails.
4625 * print.c (scm_iprin1): Use scm_macro_name.
4627 * eval.c (scm_m_define): Give names to macros as well; Only the
4628 first top-level definition gives a procedure/macro a name.
4629 Otherwise confusing names can turn up in backtraces.
4630 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4631 `name'; Give names to macros as well.
4633 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4634 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4637 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4639 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4641 (prinmacro): Removed. The code has been moved/merged into print.c
4642 in order to decrease code redundancy. We want macros to print in
4643 a way equivalent to procedures, and it would be silly to duplicate
4644 the required code. (We don't want to maintain two places.)
4645 (macrosmob): Print field is now a NULL pointer.
4647 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4648 scm_macro_transformer): New prototypes.
4649 (scm_tc16_macro): Declared.
4651 * print.c (scm_iprin1): Added code for printing of macros. Macros
4652 are now printed in a way equivalent to procedures.
4654 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4656 * procs.h (scm_closure_p): Added declaration.
4658 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4660 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4661 Shouldn't pass "heap" as the subr name.
4663 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4665 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4666 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4667 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4668 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4669 SCM_BOOL_T. Any non-false value is true.
4671 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4673 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4674 scm_gensym): Added prototypes.
4676 * symbols.c (scm_gensym): New function. This will speed up
4677 certain types of applications (such as macro systems) which
4678 generate lots of symbols.
4680 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4682 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4684 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4686 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4687 specifier, since (2) or (2 . 3) would cause SEGV.
4688 (scm_transpose_array): more argument checking fixes.
4690 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4692 * Makefile.in: Regenerated.
4694 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4696 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4698 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4700 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4702 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4704 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4705 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4708 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4709 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4710 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4711 scm_array_p, scm_array_rank, scm_array_dimensions,
4712 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4713 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4714 scm_array_prototype): Added case scm_tc7_wvect.
4716 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4718 * errno.h: prototype for scm_strerror.
4719 * error.c (scm_strerror): new procedure.
4721 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4723 * list.c (scm_list_append_x): Allow non-pair as last argument.
4724 This is consistent with the R4RS append and is probably the
4725 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4727 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4729 * stime.h: prototype for scm_times.
4730 * stime.c (scm_times): new procedure.
4731 * ioext.c (scm_fseek): if the first argument is a file descriptor
4733 (scm_ftell): if the first argument is a file descriptor call lseek
4735 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
4736 * filesys.c (scm_chmod): if the first argument is a file descriptor,
4738 (scm_chown): if the first argument is a port or file descriptor,
4740 (scm_truncate_file): new procedure.
4741 Add DEFER/ALLOW INTS to a few other procedures.
4742 (scm_fsync): new procedure.
4743 (scm_open_fdes): new procedure.
4744 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
4746 (scm_fcntl): the first argument can now be a file descriptor. The
4747 third argument is now optional.
4749 * posix.c (scm_execl, scm_execlp): make the filename argument
4750 compulsory, since omitting it causes SEGV.
4751 (scm_sync): return unspecified instead of #f.
4752 (scm_execle): new procedure.
4753 (environ_list_to_c): new procedure.
4754 (scm_environ): use environ_list_to_c. disable interrupts.
4755 (scm_convert_exec_args): take pos and subr arguments and
4756 improve error checking.
4758 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4760 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4761 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4762 argument to SCM_ASSERT. Furthermore, the name of the function
4763 should be passed as first argument when signalling
4764 SCM_WNA. (Thanks to Thomas Morgan)
4766 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4767 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4768 dispatches on the number of actual args has a default case
4769 reporting an internal error. This is a vestige from a version
4770 that mallocated a SCM vector to hold the arguments. In the
4771 current version this check is too late: if it ever happens we will
4772 have already overstepped the bounds of the array.
4774 Also, the patch [...] adds a check for too many actual arguments."
4776 mdj: Removed check for "internal programming error".
4778 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4780 * gh_io.c (gh_write): New function.
4782 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
4783 throw.c (scm_internal_stack_catch): New sibling to the other catch
4784 functions. Code moved from gh_eval.c.
4785 throw.h: Added header.
4786 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
4787 scm_internal_stack_catch.
4789 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4791 * ioext.h: fix up prototypes.
4792 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
4793 Scheme name is now dup->fdes.
4794 (scm_dup_to_fdes): make the second argument optional and
4795 fold in the functionality of scm_primitive_dup.
4796 (scm_primitive_dup): deleted.
4798 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4800 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
4801 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4802 ultrix are defined. Use setvbuf instead of setbuf.
4803 (scm_setvbuf): new procedure.
4804 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
4805 (scm_setfileno): moved from ioext.c.
4806 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
4807 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
4809 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4811 * fluids.c (scm_fluid_p): New function.
4812 * fluids.h (scm_fluid_p): New prototype.

4816 * print.c (scm_iprin1): Enter printed structures into the print
4817 state as nested data while they are printed.
4818 (print_state_fluid, print_state_fluid_num): New variables.
4819 (scm_init_print): Initialize them.
4820 (scm_iprin): If print_state_fluid carries a print_state, use that
4821 instead of creating a new one.
4822 (scm_printer_apply, apply_stub, struct apply_data): New
4823 definitions to help with calling printer functions written in
4825 * print.h (scm_printer_apply): New prototype.
4827 * struct.c (scm_print_struct): Use scm_printer_apply to call the
4828 user defined struct printer.
4830 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
4831 * fluids.h (scm_internal_with_fluids, scm_with_fluids,

4836 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
4838 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
4839 SCM_ASSERT: arg comes before pos.
4841 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4843 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
4844 to a list of length zero correctly.
4846 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4848 Supply an `fgets' method for port objects to do fast line i/o.
4849 * ioext.c (scm_read_line): New function.
4850 * genio.c (scm_gen_read_line): New function.
4851 * fports.c (scm_fgets): New function.
4852 (scm_fptob, scm_pipob): Add scm_fgets method.

4860 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4862 * ioext.h: removed scm_duplicate_port prototype.
4864 * ioext.c (scm_primitive_dup2): return the new file descriptor
4865 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
4867 (scm_fdopen): bug fix: don't try to make port unbuffered until its
4868 stream has been set.
4869 (scm_duplicate_port): deleted, there's now an implementation in
4871 (scm_primitive_dup2): do nothing if newfd == oldfd.
4873 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
4875 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
4878 * ioext.h: new prototypes.
4879 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
4881 * fluids.c (next_fluid_num): don't do
4882 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
4884 * ports.h: prototypes too.
4885 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
4887 * fports.h: prototype too.
4888 * fports.c (scm_evict_ports): moved from ioext.c.
4890 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4892 * ports.c (scm_close_port): return a boolean instead of unspecified.
4893 throw an error if an error other than EBADF occurs.
4895 * filesys.h: scm_close prototype.

4897 and ports (scsh compatible).
4899 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
4902 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
4904 * fluids.c, fluid.h: New files.
4905 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
4906 (modinclude_HEADERS): Added "fluids.h"
4908 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
4909 scm_init_fluids to initialize the fluid machine.
4910 (scm_start_stack): Initialize the fluids of the first root with
4911 scm_make_initial_fluids.

4914 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
4915 (scm_make_root): Call scm_copy_fluids to make fluid bindings
4916 unique for the new root when it has a parent.
4918 * smob.h: Include "libguile/print.h" to make scm_print_state
4921 * dynl.c (free_dynl_obj): New function to free the dynamic object
4922 data. (dynl_smob): Use it.
4923 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4924 the dynamic object data below the linking of the object to avoid
4925 memory leak when the linking code throws an error. Now the code
4926 leaks a whole dynamically linked library when must_malloc throws,
4927 but that should be much less likely.
4929 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4931 Changes to compile under gnu-win32, from Marcus Daniels:
4932 * stime.c (tzset): If tzset isn't provided, make it a NOP.
4933 (scm_localtime): Change SCM_EOF to SCM_EOL.
4934 (scm_mktime): Likewise.
4935 * socket.c: Don't include sys/un.h unless autoconf tells
4936 us Unix domain sockets are available.
4937 (scm_fill_sockaddr): Ignore Unix domain code.
4938 (scm_addr_vector): Likewise.
4939 (scm_init_addr_buffer): Likewise.
4940 (scm_socketpair): Don't include unless socketpair was

4943 * scmsigs.c (scm_pause): Don't include unless pause was found
4945 * posix.c (scm_getgroups): Don't include unless support function
4946 was found during autoconf (in this case, getgroups).
4947 (scm_setpwent): For setpwent.
4948 (scm_setegid): For setegid.
4949 * net_db.c (scm_inet_netof): Don't include unless support
4950 function was found during autoconf (in this case, inet_netof).
4951 (scm_lnaof): For inet_lnaof.
4952 (scm_inet_makeaddr): For inet_makeaddr.
4953 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.

4962 Thu Jul 10 00:22:24 1997 Jim Blandy <jimb@floss.red-bean.com>
4964 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
4965 scm_misc_error, not SCM_EOF.
4967 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
4968 arguments for formatting the error message, not SCM_BOOL_F. I
4969 think this is left over from the (eq? '() #f) days.
4971 * read.c (recsexpr): Give this a dummy definition if
4972 DEBUG_EXTENSIONS isn't #defined.
4974 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
4976 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
4979 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>

4984 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
4986 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
4987 alloca.lo will be included in @LIBLOBJS@. Something better than
4988 this should be possible.
4989 * Makefile.in: Regenerated.
4991 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4993 * simpos.h: prototype for scm_primitive_exit.
4994 * simpos.c (scm_primitive_exit): new procedure, terminates the
4995 process without unwinding the stack.
4997 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
4999 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
5000 argument and logior its components together, so the user doesn't
5001 have to do this explicitly. Also, if regexp/basic is supplied, then
5002 turn off REG_EXTENDED.
5003 (scm_init_regex_posix): New regexp/basic symbol.
5004 (REG_BASIC): #define this if it is not already present.
5006 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5008 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
5009 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
5010 (CLEANFILES): New target, clean versiondat.h, libpath.h.
5011 (DISTCLEANFILES): New target, clean *.x.
5012 * Makefile.in: Regenerated.

5016 * script.c (scm_compile_shell_switches): Add 1997 to copyright
5017 years in usage message.
5019 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
5020 * Makefile.in: Regenerated.
5022 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
5023 flag; I don't think we support it.
5024 (scm_make_regexp): Make sure the user doesn't pass the
5027 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
5029 (scm_init_regex_posix): Define constants for the REG_mumble flags;
5030 name them according to the SCSH convention: regexp/mumble.
5032 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
5034 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
5036 * Makefile.am (libpath.h): Include the values of all the standard
5037 Makefile directory variables. Print a message, but don't print
5039 (versiondat.h): Print a message, but don't print all the commands.
5040 * load.c: #include "alist.h".
5041 (init_build_info): New function.
5042 (scm_init_load): Call it.
5043 * Makefile.in: Regenerated.
5045 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
5047 * root.c: Establish a reliable catch-all handler for the new root.
5048 After all the Scheme handler function might signal an error too,
5049 and we don't want to lose that.
5050 (cwdr_inner_body): Renamed from cwdr_body.
5051 (cwdr_outer_body): New function, to establish the user's handler,
5052 and pass control to cwdr_inner_body.
5053 (cwdr): Establish the reliable catch-all handler here, and pass
5054 control to cwdr_outer_body.
5055 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
5056 the user's handler through to cwdr_outer_body.
5057 * throw.c (scm_handle_by_message): Move guts into....
5058 (handler_message): New static function.
5059 (scm_handle_by_message_noexit): New function.
5060 * throw.h (scm_handle_by_message_noexit): New prototype.
5062 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
5063 across this. Only works on GCC. Otherwise, we hope for the best.
5064 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
5065 the feeling that real thread systems will not need this...
5067 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
5069 Try to detect when people are using one version of libguile and a
5070 different version of ice-9. People have been skewing things and
5071 sending in bug reports.
5072 * Makefile.am (versiondat.h): New file to generate.
5073 * version.c: #include "versiondat.h", to get version info.
5074 (scm_libguile_config_stamp): New function.
5075 * script.c: #include "version.h".
5076 (scm_compile_switches): Call scm_version to get version number.
5077 * scmconfig.h.in, Makefile.in: Regenerated.
5078 * Makefile.in: Regenerated.
5080 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
5081 primitive definitions under their Scheme names.
5083 * Makefile.am (libguile_la_LDFLAGS): Update library version to
5084 1:2. Helps avoid confusion between installed and uninstalled libs.
5086 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
5089 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
5090 backslash from definition; this should be used like: GDB_INTERFACE;
5092 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5094 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
5095 new port unbuffered until its stream has been set.
5097 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
5099 * ports.h: new prototype.
5100 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
5102 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
5104 Make things compile neatly under Sun's C compiler.
5105 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
5106 * extchrs.c (xmbtowc): Make the second arg a normal char, not
5107 unsigned, because that's what the ANSI function takes.
5108 * extchrs.h (xmbtowc): Corresponding change to prototype.
5109 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
5111 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
5112 argument plain char *.
5113 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
5115 * tag.c (scm_tag): Remove unreachable statement.
5116 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
5117 top of the word, it should be unsigned.
5119 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
5120 is defined, to avoid warnings; it's only used in the
5121 conflict-checking code. Which might go away anyway.
5122 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
5123 conditionals; put the label definition in an #if too, to stifle
5126 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
5127 ChangeLog-threads in the distribution.
5128 * Makefile.in: Regenerated.
5130 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5132 * guile-snarf.in: Changed regexp to support CPPs that insert
5133 whitespace between lexical tokens (which munges the `%%%' snarf
5136 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5138 * load.c (scm_init_load_path): Append $(datadir)/guile to
5139 %load-path, so modules do not have to be installed in Guile's
5140 current version directory.
5142 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
5144 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
5145 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
5146 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
5147 call the sysdep functions with deferred ints.
5148 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
5149 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
5150 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
5153 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
5156 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
5158 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
5160 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
5162 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
5165 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
5167 * eval.c (scm_lookupcar1): New procedure to cope with a race
5168 condition during lookup (when using threads).
5169 (scm_lookupcar): Implement in terms of scm_lookupcar1.
5170 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
5173 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
5175 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
5176 supplied. (Change from Tim Pierce.)
5178 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
5180 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
5181 23:47:01 1997" changelog: Slots are now initialized with `#f' by
5182 default and not `()'. `#f' is the canonical non-value in Scheme,
5185 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5187 * struct.c (struct_printer): New variable that holds a handle on
5188 the Scheme variable *struct-printer*. This variable can be set by
5189 Scheme code to override the printing of structures.
5190 (scm_print_struct): If struct_printer is set, call it. If it is
5191 not set, or returns #f, print the structure in the old fashion.
5192 Include "eval.h" for scm_apply.
5194 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
5196 * struct.c (scm_struct_ref, scm_struct_set_x): Use
5197 scm_struct_i_n_words to get the number of fields, not
5198 -scm_struct_n_extra_words.
5200 On the route to fancier struct printing:
5201 * struct.c (scm_print_struct): New function to print a structure.
5202 Include "genio.h" to support it. This function doesn't do
5203 anything interesting right now, but I think it should be here
5205 * struct.h: Include "print.h" and add prototype for
5207 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
5208 print structures ourself.
5210 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5212 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
5213 before applying the handler in case it doesn't return.
5215 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
5217 * scmsigs.h, async.h: updated.
5219 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
5222 * posix.c (scm_uname): interpret only negative values as an error.
5223 Solaris normally returns a positive value.
5225 * script.c (scm_compile_shell_switches): if we are not going into
5226 an interactive repl, set scm_mask_ints to zero so that asyncs can
5229 * simpos.c (scm_system): don't ignore/unignore signals around
5232 * posix.c (scm_open_pipe): don't ignore/unignore signals around
5235 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
5236 done in boot-9.scm instead.
5238 * scmsigs.c, async.c: Major rewriting of signal handling code.
5239 (scm_sigaction): new procedure.
5240 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
5242 (scm_raise): return unspecified, throw error on failure.
5244 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5246 * regex-posix.c (scm_init_regex_posix): Register the "regex"
5247 feature, to help boot-9.scm decide whether to import the regex
5250 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5252 * eval.c: Include scmconfig.h at the beginning of the file so that
5253 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
5256 * regex-posix.c: #include "_scm.h" before conditionally #including
5257 <regex.h>; the former defines HAVE_REGCOMP.
5259 * regex-posix.c: #include <regex.h> conditionally, so the file is
5260 CPP'able (for dependency scanning) even on systems that don't have
5263 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5265 Add new R4RS-compliant syntax for keywords.
5266 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5267 regardless of the setting of the `keywords' read option.
5268 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5269 can be re-read no matter what the setting of the `keywords' read
5272 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5274 Add support for POSIX regular expressions.
5276 * regex-posix.c, regex-posix.h: New files. (Some code
5277 is taken liberally from rx/rgx.c in the old Guile dist.)
5279 * init.c: Include regex-posix.h.
5280 (scm_boot_guile_1): Call scm_init_regex_posix.
5282 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5283 Add regex-posix.[ch] sources.
5284 * Makefile.in: Regenerated.
5286 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5287 to do this automatically? It didn't for me, bleh.)
5289 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5291 * fports.c (print_pipe_port): New function.
5292 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5293 latter doesn't even take the right arguments.
5295 * Makefile.am: Increment shared lib revision number. I think
5296 sometimes the uninstalled Guile finds the installed shared lib;
5297 Gord says doing this might help. As things turned out, I can't
5298 say whether it does.
5299 * Makefile.in: Regenerated.
5301 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5302 passing it as the closure argument to scm_boot_guile. (Bill
5305 * ports.c (print_void_port, putc_void_port, puts_void_port,
5306 write_void_port, flush_void_port, getc_void_port, close_void_port,
5307 noop0): Use ANSI prototypes instead of K&R declarations, so the
5308 initialization of void_port_ptob gets aggressively type-checked.
5309 Fix arguments of print_void_port and write_void_port. (Bill

5343 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5345 * script.c (scm_find_executable): Use prototype-style definition
5346 here; apparently it's not quite right to have const in a prototype
5347 and then use a K&R declaration. I wonder if stuff like this will
5348 go away if we compile with -Wrequire-prototypes, or whatever that
5349 is... (Bernard URBAN)
5351 * scmhob.h: New text from Bernard URBAN.
5353 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5355 * script.c: Don't #define const on hpux. Configure takes care of
5356 this. (Thanks to Larry Schwimmer.)
5358 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5359 decide whether to #include <unistd.h>, instead of listing a bunch
5360 of systems. Don't #include stdio twice. Removed dyked-out
5361 definition of scm_find_impl_file.
5363 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5365 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5366 library version info to 1:0.
5367 * Makefile.in: Regenerated.

5373 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5374 throw.c: Update copyright years; these files have been worked on
5375 significantly in 1997, but only had copyright years for 1996.
5376 Also, change name of copyright holder on some from Mikael
5377 Djurfeldt to Free Software Foundation; he has signed papers
5378 assigning the changes to the FSF.
5380 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5381 reason not to give the user the option.
5383 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5384 Return #f on end-of-file when scanning table (i.e. when called
5385 with no arguments). Try to catch errors, when we can.
5386 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5388 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5389 external declarations. These are useful.
5391 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5393 * posix.c: don't include <sys/select.h> or define macros for
5394 select, since they were not used in this file.
5396 * filesys.c (scm_select): make the fifth parameter microseconds,
5397 not milliseconds. let the fourth parameter be either a real value
5398 or an integer or #f. The first, second and third arguments can
5399 now be vectors: the type of the corresponding return set will be
5401 (set_element, get_element): new static procedures.
5403 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5405 * strports.c (scm_eval_string): New function.
5406 (scm_eval_0str): Trivially re-implemented in terms of
5408 * strports.h (scm_eval_string): New extern decl.
5410 * net_db.c (h_errno): Add extern decl for this.
5412 * fports.c (local_pclose): New function.
5413 (scm_pipob): Use it in the initializer here.
5416 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5417 Use a meaningful error message when signalling an error. For
5418 this, scm_gethost must check h_errno rather than errno.
5420 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5422 * Makefile.in: Regenerated, using automake-1.1p.
5424 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5426 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5427 not SCM_UNSPECIFIED.
5429 * script.c (scm_compile_shell_switches): don't append (quit) if
5431 (scm_shell): call scm_exit_status and exit on the result of the
5434 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5436 Ensure that shared substrings are handled properly when passed to
5437 a system call or other foreign function. Many thanks to Tim
5439 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5440 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5441 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5442 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

5452 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
5453 scm_strftime), vports.c (scm_make_soft_port): use
5454 SCM_COERCE_SUBSTR to make sure shared substrings are

5459 * error.c (scm_error): Add newline to error message.
5461 * init.c (scm_init_standard_ports): Doc fix.
5463 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5465 * dynl-shl.c: Completely replaced with new code from Bernard
5468 * script.c (scm_ice_9_already_loaded): New variable.
5469 (scm_compile_shell_switches): Use it.
5471 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5473 * filesys.c (scm_input_waiting_p): add missing third argument to
5476 * stime.c (scm_localtime): copy the result of localtime before
5477 calling gmtime in case they share a buffer.
5478 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5481 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5483 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5485 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5487 * Makefile.am (check-local): New target, which causes 'make check'
5488 to run gh_test_c and gh_test_repl, with some trivial input.
5489 * Makefile.in: Rgnrtd.
5491 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5493 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5496 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5498 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5499 sure how this was supposed to work.
5500 (scm_async_click): don't send SCM_TICK_SIGNAL.
5501 (scm_init_async): don't initialize %tick-thunk.
5503 * the following change doesn't affect the Scheme interface:
5504 gc-thunk is called at the end of garbage collection. however it's
5505 no longer implemented by pretending it's a signal.
5507 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5508 system async corresponding to scm_gc_thunk.
5509 * async.h: declare scm_gc_async.
5510 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5511 gc-thunk directly, instead of going through a signal handler.
5512 (scm_gc_async): new variable, points to the GC system-async.
5513 (scm_init_async): save the GC async as scm_gc_async instead
5514 of using system_signal_asyncs.
5515 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5517 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
5519 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
5520 Don't screw up if we're interrupted.
5521 * Makefile.in: Regeneradet.
5523 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5525 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5527 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5528 we're not using AM_INIT_GUILE_MODULE any more.
5529 * Makefile.in: Reneregated.
5531 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5533 Functions for finding variable bindings, grace à Tim Pierce.
5534 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5535 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5537 Get 'make dist' to work again.
5538 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5539 * Makefile.in: Regenerated, like a surry without a fringe on top.
5541 Changes for reduced Guile distribution: one configure script,
5543 * configure.in, configure: Removed.
5544 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5545 real configure script lives.
5546 * Makefile.in, scmconfig.h.in: Regenerated.
5548 * init.c: #include "script.h", to get prototype for script.c's
5551 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5553 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5554 scm_must_malloc, not raw malloc.
5556 * script.c (scm_compile_shell_switches): Dyke out debugging output
5559 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5561 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5563 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5564 system has them. Hope this is safe. Previously
5565 sys/timeb.h was included if HAVE_FTIME was defined or if
5566 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5567 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5569 * ioext.c (scm_setfileno): add missing third argument to
5570 scm_misc_error call.
5572 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5574 * eq.c (scm_equal_p): Correctly compare strings of different
5575 varieties. (Thanks to Tim Pierce.)
5577 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5579 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5580 #! block comment must occur on a line all by itself.
5582 Move most of the guts of shell command processing into libguile,
5583 so guile.c can be very small (and eventuallly auto-generated. (I
5584 mean, generated mechanically, not self-generated. Hmm.))
5585 * guile.c, script.c, script.h: New source files.
5586 * init.c (scm_boot_guile_1): Call scm_init_script.
5587 * libguile.h: #include "script.h".
5588 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5589 targets, for new executable.
5590 (libguile_la_SOURCES): Mention script.c.
5591 (modinclude_HEADERS): Add script.h.
5592 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5593 not dynamic linking is enabled. This is because we're generating
5594 executables now. Move CY_AC_WITH_THREADS call after those, so the
5595 values of cy_cv_threads_libs captures the libs chosen above.
5596 * Makefile.in, configure, aclocal.m4: Regenerated.
5598 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5599 We don't maintain this interface any more, and it just confuses
5602 * alloca.c: #include <scmconfig.h>, not <config.h>.
5603 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5604 it'll get included in disties.
5606 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5608 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5609 be distributed, because they confuse people.
5610 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5612 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5614 * configure.in: check for presence of gethostent (not present on
5615 OpenBSD by default).
5616 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5617 * configure, scmconfig.h.in: Regenerated.
5619 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5621 * backtrace.c (scm_backtrace): Split message string across
5622 newlines properly. GCC is more tolerant of this than other

5627 Merge threads directory into libguile.
5628 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5629 threads.h: New source files.

5631 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5633 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5634 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5635 coop-threads.c.cygnus, coop-threads.h.cygnus.
5636 * configure.in: If we're using threads, include threads.o in
5638 * _scm.h, libguile.h: threads.h lives in this directory now.
5639 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5640 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5641 currently used, but brought along for information's sake.
5642 * ChangeLog-threads: log from old 'threads' directory.
5643 * Makefile.in, configure: Rebuilt.
5645 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5647 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5650 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5652 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5654 Merge GH interface library into libguile.
5655 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5656 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5657 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5658 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5660 (EXTRA_libguile_la_SOURCES): ... here.
5661 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5662 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5663 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5664 New variables, describing how to build the gh test programs.
5665 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5666 build the test programs, and we probably should have been linking
5667 libguile.la against them all along, to support AIX shared libs.
5668 Add cflags for threads to CFLAGS; add libs for threads to new
5669 variable THREAD_LIBS, used in Makefile.am.
5670 * ChangeLog-gh: log from old `gh' subdirectory.
5671 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5673 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5675 * acconfig.h: Undo change of Apr 9; including the definition of
5676 PACKAGE in the guile headers conflicts with applications' own
5678 * scmconfig.h.in: Regenerated.
5680 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

5687 when PROC is receiving no arguments.
5689 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5691 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5692 have S_IFSOCK. This is the case under Ultrix.
5694 * posix.c (scm_status_exit_val, scm_status_exit_val,
5695 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5696 Ultrix versions of WIFSTOPPED, etc., which assume that their
5697 arguments are lvalues (hmm).
5699 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5701 * eval.c: Doc fixes.
5703 * throw.c: Doc fixes; rearranged.
5705 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5707 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5709 * acconfig.h: Added entry for PACKAGE.
5710 * scmconfig.h.in: Regenerated.
5712 Changes to work with automake-1.1n, which has better libtool support.
5713 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5714 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5716 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5718 * Makefile.in: Rebuild.
5720 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5722 * stime.c (scm_mktime): take an optional zone argument.
5723 (scm_localtime): check putenv return value.
5724 (scm_strftime, scm_strptime): moved from posix.c. move #include
5726 stime.h, posix.h: update prototypes.
5727 (bdtime2c, setzone, restorezone): new static procedures.
5728 (scm_mktime, scm_strftime): use them.
5729 (scm_strftime): don't call mktime before strftime. Use
5730 filltime for return value.
5731 (filltime): convert NULL zname to #f.
5732 (scm_strptime): return a count of characters consumed, not
5733 the remaining string.
5735 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5737 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
5738 (scm_mktime): likewise.
5740 Uncomment localtime and mktime.
5742 * configure.in: add AC_STRUCT_TIMEZONE.
5744 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5746 * stime.c (scm_init_stime): don't define ticks/sec.
5747 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5748 return value problem and is still portable.)
5750 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5752 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5753 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5754 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5755 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5756 cpp_err_symbols.c): Corresponding changes.
5757 * Makefile.in: Regenerated.
5759 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5761 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5762 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5763 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5764 * putenv.c: new file, from sh-utils 1.12.
5766 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5767 since allocation isn't for Scheme objects.
5768 (scm_putenv): copy strings before placing in the environment.
5770 * stime.c (scm_current_time): throw an error if time returns -1,
5771 instead of returning #f.
5772 (scm_get_internal_real_time, scm_get_internal_real_time): use
5773 scm_long2num for return value instead of SCM_MAKINUM.
5775 * stime.h: prototypes updated.
5777 * stime.c (scm_time_in_msec): apparently unused, deleted.
5779 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5781 * configure.in: check for gettimeofday.
5783 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5784 which may be more usefully portable than a gettimeofday interface.
5786 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5788 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5790 * Makefile.in: Regenerated.
5792 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5794 * stime.c (filltime): recovered static procedure.
5795 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5798 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5799 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5801 * posix.c (scm_mknod): split the mode argument into type and perms
5802 arguments, like the extra fields returned by stat.
5804 * fports.c (scm_pipob): set the close, free and print procedures.
5805 (scm_close_pipe): new procedure.
5807 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5808 define them in boot-9.scm
5810 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5812 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5813 wan't defined. Don't include fd.h.
5815 * Previously fd.h was regenerated whenever configure was run,
5816 forcing a couple of files to be recompiled.
5818 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5819 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5820 Check for _fileno as well as _file.
5822 * ioext.c: don't fd.h.
5823 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5826 * Change the stratigy for getting information about errno
5827 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5828 generating lists of symbols during the build process, which will
5829 not always work, include comprehensive lists in the distribution.
5830 To help keep the lists up to date, the "check_signals" and
5831 "check_errnos" make targets can be used.
5833 * configure.in: don't check for a command to extract errno codes.
5834 * Makefile.am: update file lists, remove errnos.list and errnos.c
5835 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5836 check_errnos targets.
5837 (CLEANFILES): remove errnos.c and errnos.list, add
5838 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5839 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5840 * errnos.default: deleted.
5841 * cpp_signal.c: new file.
5842 * cpp_errno.c: renamed from errnos_get.c.
5843 * cpp_err_symbols, cpp_sig_symbols: new files.
5844 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5845 * error.c (scm_init_error): #include cpp_err_symbols instead of
5847 * posix.c (scm_init_posix): don't intern signal symbols. #include
5850 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5852 * strop.c (scm_i_index): allow the lower bound to be equal to the
5853 length of the string, so a null string doesn't always give an error.
5855 * posix.h: new prototypes.
5856 * posix.c (scm_status_exit_val, scm_status_term_sig,
5857 scm_status_stop_sig): new functions, as in scsh. They break down
5858 process status values as returned by waitpid.
5860 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5862 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5863 configure doesn't know about it.
5865 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5867 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5869 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5870 which defines C variables with global linkage.
5872 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5874 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5877 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5879 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5880 has time to check why this doesn't work well with continuations.
5882 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5884 * Fix shell syntax error; some shells won't tolerate
5885 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5887 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5889 * posix.c (scm_uname): throw an error if uname fails instead
5892 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5894 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5897 * async.c (scm_ints_disabled): definition moved from error.c.
5899 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5901 * acconfig.h: Removed PACKAGE.
5903 * scmconfig.h.in: Regenerated.
5905 * snarf.h: g++ says it's non-portable not to specify the first
5906 argument in a varargs declaration. I introduced the first
5907 argument by using preprocessor conditionals.
5909 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5911 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5912 (scm_freopen): use RO string macros for filename and modes.
5913 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5915 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5916 (scm_mknod): use RO string macros for path.
5918 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5919 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5921 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5922 use SCM_ROSTRINGP and SCM_ROCHARS.
5924 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5926 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5929 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5930 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5931 support for byte vectors.
5933 * print.c (scm_iprin1): Limit number of vector elements printed
5934 according to pstate->length.
5936 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5938 * backtrace.c (scm_display_error_message): don't segv if message
5941 * error.h: prototype for scm_error_scm.
5943 * error.c (scm_error_scm): new procedure, reimplements scm-error
5944 in C and uses scm_error.
5946 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5948 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5949 pointer to the Scheme variable read-hash-procedures and intern it
5950 in scm_init_read. Modify scm_read_hash_extend and
5951 scm_get_hash_procedure to use the pointer.
5953 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5955 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5956 (SCM_KEYWORD_STYLE): defined.
5958 * read.c (scm_read_opts): add a keywords option. This isn't a
5959 boolean option, in case someone wants to add support for DSSSL
5961 Setup scm_keyword_prefix symbol.
5962 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5964 I've left keyword support disabled by default, since it doesn't
5965 seem to break the module system and it gives R4RS standard behaviour.
5966 It can be reactivated with (read-set! keywords 'prefix).
5968 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5970 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5971 before constructing arbiter.
5973 * eval.c (scm_m_define): Bugfix: Check that the object is a
5974 closure before setting the procedure property!
5976 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5978 * ports.c: Removed `ungetc-char-ready?'.
5980 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5982 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5983 (idea from Mikael: make it a pair so scm_permanent object only
5985 (scm_read_hash_extend): don't call scm_permanent_object.
5986 (ideas from Mikael): if chr is already in the list, replace its
5987 procedure instead of appending it again. If proc is #f, remove
5989 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5991 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5993 * gdbint.c (gdb_read): update scm_lreadr usage.
5995 * load.h: update prototypes.
5997 * load.c (scm_primitive_load, scm_read_and_eval_x,
5998 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
6000 * read.h: add prototype for scm_read_hash_extend. Change args for
6003 * read.c (scm_read_hash_procedures): new variable.
6004 (scm_read_hash_extend): new procedure.
6005 (scm_get_hash_procedure): new procedure.
6006 (scm_lreadr): use scm_get_hash_procedure instead of an argument
6007 for extended # processing.
6008 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
6009 scm_read_token): remove case_i, sharp arguments. Change callers.
6011 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
6013 * read.h (SCM_N_READ_OPTIONS): increase to 3.
6014 (SCM_CASE_INSENSITIVE_P): define.
6016 * read.c: add case-insensitive option to scm_read_opts.
6017 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
6018 to determine whether to convert symbol case.
6019 (default_case_i): definition removed.
6020 * read.c (scm_read_token): if case_i, downcase ic before doing
6023 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6025 * configure.in: Added configuration option `guile-debug'.
6026 Configure with --enable-guile-debug if you want a bunch of extra
6027 functions used for debugging when developing Guile.
6029 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
6031 * procs.c (make-cclo): New undocumented debugging procedure: Make
6032 compiled closure with internal procedure PROC and length LENGTH.
6033 Only compiled if GUILE_DEBUG is defined.
6035 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
6037 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
6039 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
6041 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
6042 with 3 or more args internally to the evaluator.
6044 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6046 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
6047 with 3 or more args internally to the evaluator. This is mainly
6048 because we don't want to pass entry and exit points of the
6049 debug support twice, but it also seems to increase the speed of
6050 the evaluator for such calls (e. g. (+ 1 2 3)).
6052 * backtrace.c (scm_display_application): New procedure:
6053 display-application; Set fancy printing parameters individually
6054 for different types of display (backtrace, error, application).
6055 (These should of course be customizable!)
6057 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
6058 clear the CHECK-flags.
6060 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6062 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
6064 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6066 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
6067 from pairs with a GLOC in the car.
6069 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
6070 otherwise `symbol-hash' will behave badly.
6071 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
6072 we get segmentation fault!
6074 * symbols.c: Added #include "weaks.h". New functions:
6075 `builtin-bindings' and `builtin-weak-bindings'. (These will be
6076 moved to an extraneous library when we split libguile.)
6078 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6080 * filesys.c (scm_stat): stat now takes fport arguments too as
6081 documented in the manual.
6083 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6085 * debug.c (scm_single_step): Bugfix: Call continuation with
6086 scm_call_continuation instead of throwing to it.
6088 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
6090 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
6091 argument wasn't declared to be optional.
6093 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6095 * stime.c (scm_init_stime): Add feature "current-time".
6097 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6099 * throw.h: prototype for scm_exit_status.
6100 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
6101 args to derive an exit status. Allows (quit) to work from a
6103 (scm_exit_status): new function.
6106 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6108 * eval.c (scm_deval): Removed some old code.
6109 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
6111 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
6114 * symbols.c (msymbolize): Bugfix: Must initialize property list to
6117 * procs.c: Introduce the existent C function scm_thunk_p at the
6118 Scheme level as well.
6120 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6122 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
6123 used from C to easily lookup the value of a symbol in the current
6126 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6128 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
6129 scm_init_unif in this file. This will also fix a previous problem
6132 * configure.in: Added AM_MAINTAINER_MODE
6134 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6136 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
6139 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6141 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
6142 source files that are not always included in libguile but should
6143 have their dependencies calculated by automake. This variable is
6144 recognized by automake, no further magic is needed.
6145 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
6146 to deal exclusively with *.lo files, as it seems. The *.o files
6147 are built automatically when the corresponding *.lo file gets
6150 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
6152 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
6155 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
6157 * unif.c (scm_array_set_x): minor change to argument error checking.
6159 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
6161 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
6162 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
6163 They should only be included in the library at configure.in's
6165 (libguile_la_LDADD): Include the appropriate .lo files here.
6166 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
6167 so we know when to build them (and their .lo bretheren).
6168 * configure.in (LIBLOBJS): New substituted variable. We let
6169 configure decide which .o files to include in LIBOBJS, and then
6170 put the corresponding list of .lo files in LIBLOBJS. The latter
6171 is what we pass to libtool.
6172 * Makefile.in, configure: regenerated.
6174 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
6176 * symbols.c (scm_sysintern0): New function. Contains the core of
6177 old scm_sysintern but doesn't take a second value argument.
6178 (scm_sysintern): Now uses scm_sysintern0.
6179 (scm_sysintern_no_module_lookup): Renamed to
6180 scm_sysintern0_no_module_lookup and doesn't take a second value
6181 argument any longer.
6183 * symbols.h (scm_sysintern0: Added declaration.
6185 * options.c (scm_init_opts): Use scm_sysintern0 instead of
6186 scm_sysintern when interning option keys. Otherwise we risk
6187 destroying the values of already interned variables.
6189 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
6190 scheme-level boolean (use SCM_NFALSEP).
6192 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
6194 (scm_backtrace): New function. (C version of old function from
6195 boot-9.scm) Motivation: Make it possible to display backtraces
6196 without depending on boot-9.scm. (I'm uncertain if this
6197 motivation is good enough...)
6199 * root.h (scm_root_state): Add member the_last_stack_var.
6200 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
6202 * root.c (mark_root): Mark scm_the_last_stack_var.
6204 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
6207 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
6209 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
6210 1. mark_lazy_catch didn't mark the smob.
6211 2. Both functions above have standard variants:
6212 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
6213 free_lazy_catch --> scm_free0.
6215 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
6217 * throw.c (scm_internal_lazy_catch): New function.
6218 (scm_lazy_catch): Rewritten to use it.
6219 (scm_ithrow): Handle the new lazy catch representation.
6220 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
6221 that doesn't have a jmpbuf is a lazy catch clause.
6222 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
6223 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
6224 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
6226 (scm_init_throw): Register the new lazy-catch smob type.
6227 * throw.h (scm_internal_lazy_catch): decl for new function.
6229 * throw.c (scm_internal_catch): Doc fixes.
6231 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
6232 configure.in. Including this might cause problems if applications
6233 that link against libguile include their own copies of alloca, but
6234 if they're using autoconf, they should be adding libguile to LIBS
6235 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
6236 the copy in libguile, and things will be okay. (I think.)
6238 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6240 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
6242 strop.h: move prototypes too.
6244 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6246 * posix.c (scm_init_posix): don't intern EINTR since it's now done
6249 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
6250 etc. I deleted them from filesys.c long ago, but didn't
6251 notice they were here too (although ineffective since
6252 sys/stat.h wasn't included).
6254 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
6256 * eval.c: Don't define alloca in GCC case. gcc will automatically
6257 use __builtin_alloca if appropriate.
6259 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6261 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6262 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6263 that values of automatic variables are preserved. See comments
6264 for safe_setjmp for details.
6266 Change from Thomas Morgan:
6267 * variable.c: Include eq.h.
6268 (var_equal): New function.
6269 (variable_smob): Use var_equal as the discriminator for variables.
6271 * throw.c (s_throw): Remove extraneous declaration.
6273 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6274 * eval.c: Add necessary CPP cruft to support that.
6275 * configure, Makefile.in, scmconfig.h.in: regenerated.
6277 Change from Thomas Morgan:
6278 * procprop.c (scm_procedure_properties): Convert the Scheme
6279 boolean returned by scm_procedure_p into a C boolean before using
6280 it as a condition for SCM_ASSERT.
6281 (scm_procedure_property): Likewise.
6283 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6284 indications of Unixness.
6287 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6289 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6291 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6293 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6294 "unknown # object" error messages.
6296 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6297 (scm_i_index) and declare it static. Add a 'direction' argument
6298 to indicate what way the search should go.
6299 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6301 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6302 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6304 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6306 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6308 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6309 to avoid clash with various scsh forks.
6311 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6313 The following two changes (ramap.c, throw.c) are motivated by the
6314 apparent unportability of forward declarations of static arrays of
6315 the form `static foo bar[];'.
6317 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6318 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6320 * throw.c (scm_throw): Moved above scm_ithrow.
6322 * options.h: Removed the extern declarations of scm_yes_sym and
6323 scm_no_sym since these are static.
6325 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6327 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6329 * Makefile.am: remove AWK=@AWK@.
6330 Add a rule for generating errnos.list.
6331 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6333 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6334 don't extract errnos, just set a variable (avoids the
6335 need to recompile error.c just because configure is run.)
6337 * unif.h: update prototypes.
6338 * unif.c (scm_uniform_array_read,write): change the offset and
6339 length arguments to start and end, for consistency.
6341 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6343 * ioext.h: update prototypes.
6344 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6345 scm_read_line_x, it's a more general procedure using an
6346 interface from scsh. read-line and read-line! are now defined
6348 Note that the new read-line trims the terminator
6349 by default, previously it was appended to the returned string. An
6350 optional argument specifies how to process the terminator (scsh
6351 compatible). For the old behaviour: (read-line port 'concat).
6352 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6353 returns a pair, but is converted to multiple values if the scsh
6356 socket.h: update prototypes.
6357 * socket.c (scm_recvfrom): for consistency with other procedures,
6358 take start and end as separate optional arguments.
6359 (scm_recv, scm_recvfrom): don't allow the second argument
6360 to be a size, only a buffer. Change the scheme names to
6361 recv! and recvfrom!. Don't return the buffer.
6363 * ioext.h, posix.h: move prototypes too.
6364 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6365 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6366 "read.h" and "unif.h".
6367 * ioext.c: include "chars.h"
6369 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6371 * dynl.c: The dynamic linking and module registration functions
6372 are now defined even when dynamic linking is not available for the
6373 host system. Some of their functionality can be done without
6374 dynamic linking; when it's really needed, they throw errors.
6376 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6378 * configure.in: Only define DYNAMIC_LINKING when one of the system
6379 dependent functions is detected.
6380 * dynl.c (scm_dynamic_func): New function to get the address of a
6381 function in a dynamic object.
6382 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6383 produced by scm_dynamic_func as the thing to call.
6385 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6387 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6388 (scm_register_module_xxx, scm_registered_modules,
6389 scm_clear_registered_modules): New functions.
6391 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6393 * symbols.c (scm_sysintern): Renamed to
6394 scm_sysintern_no_module_lookup.
6395 (scm_sysintern): New function to take the place of the old
6396 scm_sysintern. It uses the current toplevel lookup closure to give
6397 the symbol its value. This is a temporary hack to put packages
6398 like gtcltk into their own module.
6399 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6400 us whether `scm_top_level_lookup_closure_var' has been initialized
6402 * eval.c (scm_init_eval): Set it.
6404 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6406 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6407 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6409 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6411 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6412 scm_sys_dup): deleted: FD capability will be added to other
6414 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6415 scm_fd_free, fd_smob, scm_intern_fd.
6416 (scm_open): renamed from scm_sys_open. Return a port instead of
6417 an FD object. Make the mode argument optional.
6418 (scm_sys_create): deleted, it's just a special case of open.
6419 (scm_init_filesys): move interning of constants O_CREAT etc.,
6420 here (were previously using SCM_CONST_LONG macro).
6421 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6423 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6424 include "fports.h" and <stdio.h>
6425 (scm_stat, scm_select): don't support FD objects.
6427 * error.h: adjust scm_syserror_msg prototype.
6428 * error.c (scm_syserror_msg): take an extra argument for errno.
6429 Using the global value didn't always work, since it could be
6430 reset by procedure calls in the message or args arguments.
6432 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6433 I don't understand why the check was there (and what about the
6436 * strop.c (scm_string_copy): allow shared substrings to be copied.
6438 * unif.h: corresponding change to prototypes.
6439 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6440 recognize two new optional arguments: offset and length. Allow
6441 the port argument to be an integer (file descriptor, for scsh).
6442 Include <unistd.h> for "read" prototype.
6444 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6446 * socket.c: don't include filesys.h.
6448 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6450 * Makefile.am: add AWK=@AWK@ (?)
6452 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6454 Add a rule to generate errnos.c from errnos.
6455 * error.c (scm_init_error): include errnos.c.
6456 * errnos_cnvt.awk: new file, converts the list of errno codes to
6458 * errnos_get.c: new file.
6459 * errnos.default: new file, contains errnos to try if they can't
6460 be extracted from errno.h.
6461 * configure.in: if using GCC, try and extract errno codes from
6465 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6467 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6468 * Makefile.am: Made libguile into a libtool library.
6469 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6470 Set libtool_libs to indicate that libguile is a libtool library.
6471 See guile/ChangeLog for details.
6472 * .cvsignore: ignore "*.lo", the libtool library objects.
6474 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6476 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6477 use htons in getservbyport argument.
6479 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6481 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6482 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6485 * objprop.c (scm_object_property): No need to take the CDR of the
6486 value returned by scm_object_properties, since Aug 20 change.
6488 * configure.in: When checking for struct linger, #include
6489 <sys/types.h> as well as <sys/socket.h>. I've never known
6490 <sys/types.h> to cause any portability problems, and Solaris's
6491 <sys/socket.h> needs it.
6492 * configure: Rebuilt.
6494 I think the Sun compiler has chosen a perverse way to interpret
6495 ANSI declarations combined with K&R definitions. We'll
6496 appease it a little bit. But when it invades France, we fight.
6497 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6498 * print.h (scm_iprlist): Here too.
6499 * numbers.c (scm_divbigdig): Change definition to match
6500 declaration in numbers.h.
6501 * unif.c (scm_makflo): Change definition to match declaration in
6504 * init.c (scm_boot_guile): Don't return the value of
6505 scm_boot_guile_1. This function doesn't return a value;
6506 scm_boot_guile_1 doesn't return a value (or return at all).
6508 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6511 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6512 compile. I have a feeling this function is a bad idea anyway ---
6513 one should always test for features, not systems.
6515 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6516 semicolons. Only pure luck kept this from being noticed earlier.
6518 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6520 * socket.c (scm_recvfrom): Added missing semicolon.
6522 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6524 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6525 the buffer and start and end positions for scsh networking
6528 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6530 * configure.in: Revert previous change to this file; the problem
6531 is due to transient automake weirdness.
6532 * configure: Rebuilt.
6534 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6535 PLUGIN/guile.libs. configure generates the latter from the former.
6536 * Makefile.in: Rebuilt.
6538 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6539 need this if we install scripts, like guile-snarf.
6540 * configure: Rebuilt.
6542 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6544 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6546 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6548 * socket.c (scm_addr_vector): fix faulty scm_listify.
6550 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6552 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6553 style block comment is no longer considered an error.
6555 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6557 * PLUGIN/guile.libs.in: New file.
6558 * PLUGIN/guile.libs: Removed from repository.
6559 * configure.in: Create PLUGIN/guile.libs from
6560 PLUGIN/guile.libs.in. This is for including additonal libraries
6561 needed for dynamic linking.
6562 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6563 instead of PLUGIN/guile.libs.
6565 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6567 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6569 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6570 occurrences of the given element from the list, not just the
6571 first. This is how the Emacs Lisp functions behave, how the
6572 analogous Common Lisp functions behave, and (I believe) how the
6573 older Maclisp functions worked. I realize that this change may
6574 break code, but it seemed better to break it before the Guile
6577 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6578 Their prototypes were already present in gc.h, but they weren't
6580 (scm_init_storage): Initialize scm_protects.
6581 * root.c (scm_protects): New element of scm_sys_protects.
6583 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6585 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6587 * libguile.h: Added #include "libguile/net_db.h".
6589 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6590 30 change. That file is only meant for communication between the
6591 configuration process and load.c. If code linked against libguile
6592 wants to get at the paths mentioned in libpath.h, it can call
6593 functions declared in load.h.
6595 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6597 * libguile.h: Removed #include "libguile/fdsocket.h"
6599 * net_db.c: Added #include <sys/socket.h>.
6601 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6603 * filesys.c (scm_input_waiting_p): use select in preference to
6604 FIONREAD, since the latter doesn't detect EOF.
6605 Throw error if neither select nor FIONREAD available.
6607 * socket.c (scm_connect): take a port, not a fd object.
6608 (scm_fill_sockaddr): throw an error if fam is not recognised.
6609 (scm_bind): use scm_fill_sockaddr.
6610 (scm_listen): take a port, not a fd object.
6611 (scm_accept): take and return a port. return #f in the car if
6612 address can't be got
6613 (scm_sock_fd_to_port): new procedure.
6614 (scm_socket): use scm_sock_fd_to_port.
6615 (scm_addr_vector): throw error if unrecognised address type.
6616 take an extra argument with the calling procedure name.
6617 (scm_getsockname): take a port. return #f if address can't be got.
6618 (scm_getpeername): take a port. return #f if address can't be got.
6619 (scm_recvfrom): take a port. return #f for address component if can't
6621 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6622 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6624 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6626 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6627 use separate data pointers, to allow them to be designed
6628 independently and reused.
6629 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6630 Renamed from catch_body, catch_handler, and uncaught_throw; made
6632 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6634 (scm_catch): Use the above.
6635 (scm_throw): Don't bother printing a message for an uncaught
6636 throw; we establish a default handler in init.
6637 * throw.h (scm_internal_catch): Prototype updated.
6638 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6640 (struct scm_body_thunk_data): New structure, used as data
6641 argument to scm_body_thunk.
6642 * init.c (struct main_func_closure): New structure, packaging up
6643 the data to pass to the user's main function.
6644 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6645 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6646 scm_internal_catch to establish a catch-all handler, using
6647 scm_handle_by_message. This replaces the special-case code in
6649 (invoke_main_func): Body function for scm_internal_catch; invoke
6650 the user's main function, using the main_func_closure pointer to
6651 decide what to pass it.
6652 * root.c (struct cwdr_body_data): Remove handler_proc member.
6653 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6654 (cwdr_handler): Removed.
6656 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6658 * socket.h (SCM_P): update bind prototype.
6659 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6660 include "feature.h".
6661 (scm_socket): return a port, not a file descriptor object.
6662 include "fports.h" and <unistd.h>
6663 (scm_bind): take a port, not a file descriptor object.
6664 take an extra argument for address args.
6666 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6667 INADDR_NONE, INADDR_LOOPBACK.
6669 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6671 * init.c: include net_db.h and not fdsocket.h.
6672 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6674 * Makefile.am: corresponding changes.
6675 * socket.h: renamed from fdsocket.h, fix names.
6676 * net_db.h: renamed from socket.h, fix names.
6677 * socket.c: renamed from fdsocket.c.
6678 remove _sys from procedure names.
6679 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6680 add "socket" to features list.
6681 * net_db.c: renamed from socket.c.
6682 remove _sys from procedure names.
6683 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6684 add "net-db" to features list.
6685 include "net_db.h". don't include <sys/socket.h> or
6688 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6690 * tags.h (scm_tags): Removed comma at end of last enumerator.
6692 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6694 Don't use GCC extensions to allocate space for debugging frames.
6695 (Here he goes again! Why do we put up with this?!)
6696 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6697 an scm_debug_info structure, not an in-line array of them. Add
6698 'info' member, to say how many vect elements we've used, for eval
6700 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6701 a new variable debug_info_end to mark the end of vect, instead of
6702 the address of the 'info' pointer itself.
6703 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6704 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6705 (SCM_APPLY): Explicitly allocate space for debug.vect.
6706 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6707 * stacks.c: Adjusted for new debug frame structure.
6708 (RELOC_INFO, RELOC_FRAME): New macros.
6709 (stack_depth, read_frames): Use them, and new scm_debug_frame
6710 element 'info', instead of magically knowing that eval frames have
6711 an info pointer sitting after vect.
6712 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6714 (scm_init_stacks): Formatting tweaks.
6716 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6718 Give GCC more control flow information, so it can be sure that
6719 variables aren't used uninitialized.
6720 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6721 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6722 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6723 scm_misc_error): Tell GCC that these functions never return.
6724 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6725 out the field type, call abort if SCM_ASSERT returns, to placate
6727 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6728 scm_wta ever returns. We can't handle this case anyway, and this
6729 gives the optimizer more information.
6730 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6731 scm_wta ever returns.
6733 In some cases, the code is fine, but GCC isn't smart enough to
6734 figure that out; this usually happens when one variable is only
6735 initialized and used when a particular condition holds true, and
6736 we know that condition will never change within a given invocation
6737 of the function. In this case, we simply initialize the variables
6738 to placate the compiler, hopefully to a value which will cause a
6739 crash if it is ever actually used.
6740 * print.c (scm_iprin1): Initialize mw_pos.
6741 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6742 * throw.c (scm_ithrow): Initialize dynpair.
6743 * unif.c (scm_uniform_vector_ref): Initialize cra.
6744 * struct.c (init_struct): Initialize prot.
6745 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6747 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6748 if EXPR contains no expressions.
6750 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6752 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6753 cause an infinite loop (???). So much for the algebraic
6754 equivalency of variable-sized arrays and alloca...
6756 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6758 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6759 a SCM boolean, not a C boolean.
6761 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6763 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6764 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6765 rules for raising scm_mtrigger. Previously, unfortunate but not
6766 unlikely circumstances could result in almost constant invokation
6767 of the gc. Now, this situations should be less likely, but they
6768 are not prevented completely.
6770 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6772 * numbers.c (scm_fuck): Procedure removed; looks like old test
6774 * numbers.h: Prototype removed.
6776 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6778 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6779 array to a pointer, to match my Nov 21 change in eval.c.
6781 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6783 * libguile.h: Added #include "libguile/backtrace.h", #include
6784 "libguile/stacks.h".
6786 * strings.c (scm_string scm_make_string scm_string_ref
6787 scm_string_set_x scm_string_equal_p scm_string_append):
6788 Bugfix according to scm patch from Aubrey Jaffer:
6789 Corrected long-standing
6790 (not (eqv? (integer->char 128)
6791 (string-ref (make-string 1 (integer->char 128)) 0)))
6792 bug found by John Kozak <jk@noontide.demon.co.uk>.
6794 * strports.c, strports.h: Make scm_eval_0str return the value of
6795 the last expression evaluated (previously, it returned void).
6797 * strports.c, strports.h: New function: scm_read_0str. Does what
6800 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6802 * simpos.c (scm_getenv): return #f if string can't be found in the
6803 environment instead of throwing an exception, for compatibility
6804 with numerous other systems.
6806 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6808 * Makefile.am (.c.x): Use guile-snarf.
6809 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6811 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6813 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6815 * backtrace.c (scm_display_error_message): Made non-static, and
6816 renamed from display_error_message.
6817 * backtrace.h (scm_display_error_message): Added extern decl.
6818 * throw.c (uncaught_throw): Use it to display the error message.
6820 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6822 * inet_aton.c: Use #if 0, not #ifdef 0.
6824 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6826 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6827 to convert the returned value.
6828 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6829 the offset argument.
6831 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6833 Add new interface to catch/throw, usable from C as well as
6835 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6836 (scm_internal_catch): New function, replaces...
6837 (scm_catch_apply): Deleted.
6838 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6839 mechanism which is a bit more code, but can be used nicely from C
6840 and implement the Scheme semantics as well.
6841 (scm_internal_catch): This is the replacement; it's named after
6842 the analogous function in Emacs.
6843 (scm_catch): Reimplemented in terms of the above.
6844 (struct catch_body_data, catch_body, catch_handler): New
6845 functions, used by scm_catch.
6846 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6847 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6848 support for new cwdr.
6850 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6853 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6855 * acconfig.h: Added DYNAMIC_LINKING symbol.
6856 * configure.in: Add option and checks for dynamic linking.
6857 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6858 dynl.h: New files for dynamic linking support.
6859 * Makefile.am (libguile_a_SOURCES):
6861 (modinclude_HEADERS): Added "dynl.h".
6862 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6864 * init.c (scm_boot_guile_1): Call
6865 scm_init_dynamic_linking to initialize dynamic linking support.
6867 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6869 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6870 (as we Schemers say). It needs to be global, so that I can tweak
6871 it for the proper operation of unexec.
6872 (scm_boot_guile_1_live): New variable, see above.
6874 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6876 * guile-snarf.sh: Removed.
6877 * PLUGIN/guile.libs: Added dependency for -lm.
6878 * acinclude.m4: Renamed from aclocal.m4.
6879 * PLUGIN/greet: Removed.
6880 * Makefile.am, aclocal.m4: New files.
6881 * configure.in: Updated for Automake.
6883 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6885 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6886 and not top_level_lookup_thunk_var.
6888 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6890 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6892 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6894 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6895 Scheme function, instead of syntax. Single argument is now a
6898 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6900 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6901 scm_ra_divide): Properly terminate statements passed as arguments
6902 to IVDEP macros. (Thanks to Bernard Urban.)
6904 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6905 with non-constant sizes. (Thanks to Bernard Urban.)
6907 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6909 It's an "eval closure", not an "eval thunk." A thunk is a
6910 function of no arguments.
6911 * root.h (struct scm_root_state): Renamed
6912 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6913 (scm_top_level_lookup_closure_var): Renamed from
6914 scm_top_level_lookup_thunk_var.
6915 * root.c (mark_root): Uses changed.
6916 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6917 * init.c (scm_start_stack): Uses changed.
6918 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6919 Change scheme-visible name to *top-level-lookup-closure* from
6920 *top-level-lookup-thunk*.
6922 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6924 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6925 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6927 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6929 * gc.c (struct scm_heap_seg_data): Doc fixes.
6931 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6932 sweeping. Then, prepend each segment's free cells to its
6933 freelist, rather than wiping out the old value. (Thanks to Marius
6936 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6937 scm_check_freelist, scm_debug_newcell): New functions and
6938 variables, for debugging freelist problems.
6939 * pairs.h (SCM_NEWCELL): New debugging version added.
6940 * gc.h (scm_debug_newcell): Added extern declaration, used by
6941 debugging version of SCM_NEWCELL.
6943 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6945 On some systems <libc.h> conflicts with <unistd.h>, and should not
6946 be #included at all.
6947 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6948 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6949 * configure.in: Call it.
6950 * posix.c, filesys.c: Use its results to decide whether or not to
6952 * configure, scmconfig.h.in: Rebuilt with autoconf and
6955 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6957 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6958 pointer to the stdio stream before calling scm_setbuf0, so the
6959 latter will be able to retrieve it. I'm surprised this didn't
6960 segfault earlier. (Thanks to Christopher Lee.)
6962 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6964 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6967 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6969 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6970 number of stack narrowing specifier pairs. The first specifier in
6971 a pair controls inner border, the second the outer border. A
6972 number means cut that number of frames, a procedure object means
6973 cut until that object is found in operator position in a frame.
6975 * root.c (cwdr): Bugfix.
6977 * read.c: Recording of positions disabled by default.
6979 * procs.c (scm_closure_p): New function.
6981 * posix.c (scm_tmpnam): New function.
6983 * load.c: Added #include "throw.h".
6984 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6987 * load.c, load.h (scm_read_and_eval_x): New function.
6989 * eval.c: Renamed debug option "deval" to "debug".
6991 (scm_eval_x): `eval!' is no longer accessible from the scheme
6992 level. Motivation: We can't allow operations which introduce
6993 glocs into the scheme level. Guile's type system can't handle
6994 these as data. Use `eval' or `read-and-eval!' as replacement.
6996 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6997 SCM_CONSP since this is a macro!; Set vframe.prev to
6998 scm_last_debug_frame instead of 0. In this way we can look
6999 "above" the virtual start stack frame if we wish.
7000 (scm_debug_hang): New function: Useful for debugging Guile in
7001 certain tricky situations. Will probably be removed later...
7003 * debug.h: Changed semantics of debug option "backtrace". This
7004 option now only indicates whether we want automatic backtrace at
7007 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7009 * ports.c: #include "filesys.h"
7010 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
7012 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
7013 Motivation: This is system specific code which is related to file
7014 I/O. It also may use select. Added code by Gary Houston to
7015 detect presence of character in stdio buffers.
7017 * libguile.h: #include "libguile/libpath.h"
7019 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
7020 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
7021 SCM_SITE_DIR; Install libpath.h among the other include files.
7023 * load.c, load.h (scm_sys_package_data_dir): New function.
7025 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7027 * stacks.h: Bugfix: Don't use tail-array length field as stack
7028 length field! This screwed GC.
7030 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7032 * _scm.h: Added #ifndef around definition of macros min and max.
7034 * __scm.h: Added hooks for threads to plugin to in ints protection
7035 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
7036 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
7037 the main code in these macros duplicated and spread over multiple
7038 files. Renamed SCM_THREADS_SWITCHING_CODE ->
7039 SCM_THREAD_SWITCHING_CODE.
7041 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
7043 * snarf.h: New file.
7044 * guile-snarf.sh: New file.
7045 * Makefile.in (inner_h_files): Added snarf.h
7046 (ancillary, install, uninstall, distclean): Added actions for
7048 (.c.x): Use guile-snarf.
7049 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
7050 (gen_c_files): Note that these depend on guile-snarf.
7051 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
7052 now in "snarf.h". Added #include "snarf.h" to get them.
7053 * libguile.h: Added #include "snarf.h".
7054 (Patches applied and tweaked by Jim Blandy.)
7056 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7058 * socket.c: Use K&R style declaration for 'close'; the GNU coding
7059 standards suggest against providing prototypes for system
7060 functions. Thanks to Greg Troxel.
7062 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
7064 * strports.c (scm_eval_0str): New function.
7065 #include "read.h", to get prototype for scm_read.
7066 * Makefile.in (strports.o): Update dependencies.
7067 * strports.h: New prototype.
7069 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
7070 scheme name from "int?" to "integer?". It seems to do the job.
7071 * numbers.h: Rename prototype too.
7072 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
7075 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
7076 scm_num_eq_p): Rename these according to R4RS conventions: call
7077 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
7078 to making libguile R4RS compliant without ice-9...
7080 * load.c (scm_sys_search_load_path): Search for files under all
7081 extensions listed in the %load-extensions variable. If FILENAME
7082 is absolute, return it unchanged, without searching the load path.
7083 (scm_loc_load_extensions): New variable, pointing to
7084 %load-extensions' value cell.
7085 (scm_init_load): Initialize it, and the value it points to.
7086 (scm_primitive_load_path): Improve error reporting.
7088 * load.c (scm_loc_load_hook): New variable, pointing to value cell
7089 of new Scheme variable %load-hook.
7090 (scm_primitive_load): Apply %load-hook to filename.
7092 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
7094 * configure.in: add tests for figuring out whether buffered data
7095 is available in a FILE structure, which is needed by char-ready.
7097 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
7100 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
7101 exceptions using misc_error instead of syserror. It seems a bit
7102 odd to throw an exception if a string can't be found in the
7103 environment, but it's consistent with open-file, stat etc.
7104 (simpos.h): remove sys_ from getenv.
7106 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
7107 occurs, throw an error instead of returning errno. Return value
7109 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
7111 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
7113 * filesys.c (scm_stat2scm): derive file type and permissions from
7114 the stat mode and append them to the returned vector.
7115 There isn't much overhead in doing this and it avoids the need to
7116 work with S_IRUSR et al. in Scheme.
7117 Define symbols scm_sym_regular etc.
7118 (scm_init_filesys): don't intern S_IRUSR etc.
7120 * load.c: change s_try_load and s_try_load_path to s_primitive_load
7121 and s_primitive_load_path.
7123 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
7125 * error.h: don't declare error symbols. prototype for scm_misc_error.
7127 * stackchk.c (scm_stack_overflow_key): defined here instead of in
7130 * error.c: use SCM_SYMBOL to set up error keys.
7131 scm_misc_error: new procedure.
7133 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7135 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
7136 between `#!' and `!#' is ignored.
7137 (skip_scsh_block_comment): New function.
7139 * feature.c (scm_set_program_arguments): New argument, FIRST.
7140 * feature.h: Update prototype.
7141 * init.c (scm_boot_guile_1): Pass new argument to
7142 scm_set_program_arguments.
7144 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7146 * init.c (scm_start_stack): Don't initialize scm_progargs here.
7147 (scm_boot_guile): Call scm_set_program_arguments here, later than
7148 the old initialization.
7150 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
7151 initialization procedure.
7152 - Delete in, out, err arguments; there are other perfectly good
7153 ways to override these when desired.
7154 - Delete result argument; this function shouldn't ever return.
7155 - Rename init_func argument to main_func, for less confusion.
7156 - Delete boot_cmd argument; main_func is more general.
7157 -Add 'closure' argument, to help people pass data to main_func
7158 without resorting to global variables.
7159 - Abort if reentered; don't bother returning an error code.
7160 - Call scm_init_standard_ports to set up the default/current
7161 standard ports; no need to pass them to scm_start_stack.
7162 - Remove code to evaluate the boot_cmd, and start the repl; let
7163 the user do something like that in main_func if they want.
7164 - Remove code to package up a return value; main_func can do any
7166 - Call exit (0), instead of returning.
7167 (scm_start_stack): Don't initialize the I/O ports here; that's
7168 weird. Delete in, out, err arguments. Move guts to
7169 scm_init_standard_ports, scm_stdio_to_port.
7170 (scm_init_standard_ports): New function, to set up current and
7171 default standard ports.
7172 (scm_start_stack, scm_restart_stack): Make these static.
7173 * init.h (scm_boot_guile): Adjust declaration.
7174 (scm_start_stack, scm_restart_stack): Remove externally
7175 visible declarations for these.
7176 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
7178 * fports.c (scm_stdio_to_port): New function. Its guts used to be
7179 written out several times in scm_start_stack.
7180 * fports.h: New declaration for the above.
7182 * feature.c (scm_set_program_arguments): New function.
7183 * feature.h: New declaration for the above.
7185 * ports.c: Formatting tweak.
7187 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
7189 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
7190 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
7191 for obtaining the address of a car or cdr field. Motivation:
7192 &SCM_CXR make assumptions about the internal structure of the
7195 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
7196 Motivation: see SCM_CXRLOC.
7198 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
7199 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
7200 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
7201 Motivation: Safer use. Some other macros are defined in terms of
7202 these operations. If these are defined using the SCM_SETCXR
7203 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
7204 to inefficiency and an <e1> with side-effects could potentially
7205 break. Also, these particular operations are heavily utilized in
7206 the garbage collector. In unoptimized code there will be a
7209 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
7210 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
7211 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
7212 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
7213 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
7214 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
7215 vports.c: Cleaned up use of pairs: Don't make any special
7216 assumptions about the internal structure of selectors and
7217 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
7218 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
7219 (Among other things, this change makes it easier to build Guile
7220 with certain compilers which have problems with casted lvalues.)
7222 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7224 * stacks.c: Improve selection of relevant stack frames when making
7225 a stack object. Introduce one level of indirection in the stack
7226 object to make it possible to "narrow" to a certain region of the
7227 stack. This facilitates making use of more clever algorithms (not
7228 implemented) for selecting relevant frames and gives a cleaner
7229 design since selection of frames can be done independently of
7230 extraction of frames from the real stack.
7231 (scm_stack_id): Also take #t as argument which means look at
7234 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
7235 Turn n_tail into an integer directly representing current number
7236 of frames in stack. Add field tail.
7238 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
7240 * debug.c (scm_make_memoized): Made it available at scheme level.
7241 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
7242 SCM_NIMP before applying heavier predicates in argument checking.
7243 (scm_local_eval): Also take memoized object as argument.
7245 * backtrace.c (scm_display_error): Just a safety measure: Stacks
7246 aren't created with zero length, but should such a strange
7247 creature suddenly turn up...
7249 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
7251 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
7252 `del', for the sake of C++ compilers. (Patch applied by JimB.)
7254 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
7256 * variable.c (scm_make_variable): Make the name hint optional, as
7258 (anonymous_variable_sym): Renamed from variable_sym. All uses
7261 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7262 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7263 of scm_primitive_load_path was also changed to
7264 "primitive-load-path", from "%try-load-path". Callers changed.
7265 We'd like to respect the convention that a function named
7266 "try-mumble" should behave just like the function called "mumble",
7267 but return #f instead of signalling some error.
7268 * load.h: Rename prototypes.
7270 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7272 * print.c (make_print_state, grow_print_state), print.h: Modified
7273 the print state representation: Don't use a tail array for
7274 recording of circular references. Resizing of the print state
7275 structure invalidates the print state pointer. To avoid passing
7276 around an indirect print state reference to all printing
7277 functions, we instead let the print state reference a resizable
7280 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7282 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7283 Don't crash when passed an improper list terminated by a
7284 non-immediate value.
7286 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7288 Allocate data for structures on an eight-byte boundary, as
7289 required by the tagging system.
7290 * struct.c (alloc_struct): New function.
7291 (scm_make_struct, scm_make_vtable_vtable): Call it.
7292 * struct.h (scm_struct_n_extra_words): Bump to 3.
7293 (scm_struct_i_ptr): New "field".
7294 * gc.c (scm_gc_sweep): When we need to free the data, use the
7295 information stored by alloc_struct to find the beginning of the
7296 block allocated to the structure, so we can free it.
7298 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7300 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7303 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7304 (scm_debug_info): New member: id.
7306 * stacks.c: Stacks are now represented as structs; Stacks have an
7307 id given to them by `start-stack'.
7308 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7310 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7311 Changed stack representation.
7313 * debug.c (scm_procedure_name): Try procedure property `name' for
7314 compiled closures aswell.
7316 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7318 * eval.c: scm_i_name moved to gsubr.c
7319 (scm_m_define): Record names of all kinds of procedure
7320 objects. (Earlier, only closures were recorded.)
7322 * procprop.h: Added declaration of scm_i_name.
7324 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7325 (scm_make_gsubr): Record names of compiled closures.
7327 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7329 * debug.c, debug.h: Removed obsolete code.
7331 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7332 stacks.c: Renamed regs --> scm_contregs.
7334 * print.c (scm_free_print_state): Cleanup print state before
7335 returning it to pool. It is better to do it here than in
7336 scm_prin1 since scm_prin1 is called often.
7338 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7339 s_set_source_property_x): Check that first argument is a pair or a
7342 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7343 scm_i_line, scm_i_column and scm_i_breakpoint global.
7345 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7346 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7349 * debug.h: Added debug object smob declaration and macro
7352 * configure.in: Build with backtrace.o and stacks.o if debug

7356 backtrace.h, stacks.c and stacks.h.
7358 * symbols.c (scm_sym2ovcell): Fixed documentation.
7360 * _scm.h (min, max): Added.
7362 * async.c: Moved `min' macro to _scm.h.
7364 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7365 SCM_BACKTRACE_INDENT.

7371 * print.h: Added selector SCM_PRINT_STATE.
7373 * print.c: New functions: scm_make_print_state,
7374 scm_free_print_state.
7376 * print.h: Added declarations for scm_make_print_state,
7377 scm_free_print_state.
7379 * debug.c (scm_m_start_stack): New acro.
7381 * debug.h: Small cleanup.
7383 * init.c (scm_boot_guile_1): Moved scm_init_debug below

7411 More prototype-related changes from Marius Vollmer:
7412 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7413 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7414 * ports.h (ptobfuns): Added prototypes. This means some casting in
7416 * fports.c: Added casts for initializations, since the functions
7417 are defined to take FILE * as their stream argument, not SCM.
7418 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7419 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7420 to `char *str_data' to conform to prototype.
7422 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7424 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7426 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7428 * stime.c, stime.h: use SCM_P method.
7430 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7432 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7433 be given at least two arguments. Insist that lst's last element
7434 be a list, but don't make any requirements of its predecessors.
7436 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7438 * eval.c (scm_nconc2last): Revert last change; there seems to be
7439 other stuff going on here.
7441 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7443 * eval.c (scm_nconc2last): Make sure that each element of lst
7444 (which is a list of argument lists, except for the tail) is a
7445 proper list, i.e., finite and terminated by '().
7447 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7449 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7452 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7453 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7456 * vectors.c (scm_make_vector): Fill vectors with the undefined
7457 value, to help make Guile Scheme code more portable to other
7460 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7461 * symbols.h, tags.h: Doc fixes.
7463 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7465 * async.c (scm_take_signal): Doc fixes.
7467 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7469 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7470 want to subtract it from the modulus; we just want to leave it
7473 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7475 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7478 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7480 * throw.c (scm_catch_apply): Finished implementation of
7483 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7485 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7487 (scm_init_filesys): set "i/o-extensions" feature.
7490 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7492 * Makefile.in (root.o): Correct dependencies.
7494 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7496 * Makefile.in: Added dependency entry for root.o.
7498 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7499 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7501 * init.c (scm_start_stack): Set initial root continuation number
7504 * procs.c: New function: scm_thunk_p.
7506 * procs.h: Added declarations of scm_thunk_p.
7508 * root.c: Renamed `call-with-new-root' -->
7509 `call-with-dynamic-root'.
7510 (cwdr): Removed allocation of new root state. This should be done
7511 separately by use of scm_make_root.
7512 (scm_apply_with_dynamic_root): New function: Does what it
7513 sounds like. Needed when spawning threads.
7515 * root.h: Added member last_debug_frame to root state.
7516 Added #include "libguile/debug.h"
7518 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7519 arguments. The motivation is that code in root.c needs catch
7520 functionality, and we want to avoid code duplication.
7521 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7522 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7523 handlers that run without popping the stack into the dynwind
7526 * throw.h: Added prototypes for scm_catch_apply and
7529 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7531 * root.h (scm_root, scm_set_root): Decouple thread support details
7532 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7533 SCM_SET_THREAD_LOCAL_DATA.
7535 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7536 and tortoise scanning loop.
7538 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7540 * Makefile.in: Rebuild dependencies.
7542 * libguile.h: #include "libguile/print.h" before "smob.h", since
7543 the latter uses the print_state structure.
7545 * throw.c (scm_ithrow): Use the correct variable when checking to
7546 see if a given element of scm_dynwinds is a valid catch.
7548 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7549 structure, abort; don't just silently ignore the garbage.
7551 * _scm.h: #include "print.h" here, since it seems to be used just
7553 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7554 strports.c, unif.h: Don't #include "print.h".
7556 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7558 * feature.h (scm_loc_features): Removed external declaration.
7559 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7561 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7563 * feature.c (scm_init_feature): Added threads feature (needs to be
7564 initialized here, since features doesn't exist when
7565 scm_init_threads is called).
7567 * libguile.h: Added #include "libguile/../threads/threads.h".
7568 (This is a kludge to get thread support working. This should be
7571 * configure.in, acconfig.h: Added flags for thread support.
7573 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7576 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7577 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7580 * _scm.h: Added conditional #include "threads.h"
7582 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7583 SCM_THREADS_SWITCHING_CODE.
7585 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7586 allocate the basic dynamic root object.
7587 (scm_boot_guile): Added call to scm_init_root.
7589 * root.c, root.h: Added root smob.
7590 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7591 functions: Implements dynamic roots mostly according to spec in
7592 SCM manual. Main difference is that the second argument is a
7593 throw handler rather than an error "thunk".
7595 * root.h: Added declaration of scm_init_root.
7597 * root.c: Added #include "genio.h", #include "smob.h", #include
7598 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7600 (scm_init_root): Added #include "root.x".
7602 * throw.c: Added #include "stackchk.h"
7603 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7604 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7605 can be used in scm_call_with_new_root; Added reenabling of stack
7606 checking when catching a throw.
7608 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7610 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7612 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7613 element is not found, as per R4RS.
7615 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7617 * list.c: Doc fixes throughout.
7619 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7621 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7622 declare the char * to be const. Avoids a warning in rgx.c.
7624 * ports.h: spelling fix.
7626 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7629 * load.c (scm_sys_try_load_path): throw an error if file not found
7630 (like it says it in NEWS).
7632 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7634 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7635 PROPS slot to '(), not #f; it's an empty alist.
7637 * throw.h, throw.c: Use SCM_P instead of #if hair.
7639 Remove special support for uncaught throws; see throw.c for
7641 * throw.c (uncaught_throw): New function.
7642 (scm_ithrow): Call uncaught_throw if we don't find a throw
7643 target; don't mess with scm_bad_throw_vcell.
7644 (scm_bad_throw_vcell): Variable deleted.
7645 (scm_init_throw): Don't initialize it.
7647 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7650 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7652 * numbers.c (scm_istr2int): If the number is short (as most
7653 numbers are), just call scm_small_istr2int to deal with it.
7654 (scm_small_istr2int): New function, created by un-#ifdefing the
7655 non-bignum version of scm_istr2int and renaming it.
7657 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7659 * load.c (scm_sys_try_load): don't check whether value returned
7660 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7661 Change the Scheme name from %try-load to primitive-load.
7663 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7664 Can avoid passing a message, allowing it to be derived in the
7665 error handler (e.g., if we want to throw to the key both from
7668 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7670 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7671 references now have a new appearance which is more compact and
7672 also gives a clue about what the target of the reference is.
7673 By setting parameters in the print state, more fancy printing can
7674 be achieved. This is used by the (not yet commited) backtrace
7677 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7679 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7682 * print.c: Added #include "struct.h". Removed function
7685 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7686 scm_iprin1. Removed prototype for scm_prlist.
7688 * arbiters.c (prinarb),
7689 async.c (print_async),
7690 debug.c (prindebugobj, prinmemoized),
7691 eval.c (prinprom, prinmacro),
7692 filesys.c (scm_fd_print, scm_dir_print),
7694 mallocs.c (prinmalloc),
7695 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7696 smob.h (scm_smobfuns),
7697 srcprop.c (prinsrcprops),
7699 unif.c, unif.h (scm_raprin1, rapr1),
7700 variable.c (prin_var): Changed argument `int writing' to
7701 `scm_print_state *pstate'.
7703 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7704 that it will be called before scm_init_print.
7706 * print.c (scm_prin1): Print states are now allocated when calling
7707 scm_prin1 and then passed around to all printing functions as an
7708 argument. A cache `print_state_pool' enables reuse of print
7710 (scm_make_print_state): New function.
7711 (scm_iprin1): Adaption to print states.
7712 (scm_iprlist): An initial "hare and tortoise" scan brings down
7713 time complexity to O (depth * N). (Better time complexity will be
7714 achieved when the printing code is completely rewritten.)
7716 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7718 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7719 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7720 it gets done whether or not the cache variable has a value.
7722 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7724 Distinguish #f and ().
7725 * __scm.h: #undef SICP.
7726 * pairs.h (SCM_EOL): Delete this definition, equating it with
7728 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7729 the value it used to have. Doc fixes, too.
7731 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7733 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7734 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7735 Lord's implementation of structs, allowing for tail arrays as
7736 described in the manual. Also fixed some bugs. (Both the interface
7737 and the implementation should be improved.)
7739 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7741 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7742 People who whish to see the source can do `(print-enable 'source)'.
7743 Removed #ifdef DEBUG_EXTENSIONS.
7745 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7747 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7748 integer (assuming for now accepting an integer is a good thing).
7750 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7751 %S will be used instead for write'ing arguments.
7753 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7754 asserts. fix a few other asserts.
7755 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7756 scm_uniform_vector_ref, scm_array_set_x,
7757 scm_dimensions_to_unform_array): change args in
7758 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7759 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7760 scm_substring_fill_x): likewise.
7761 gsubr.c (scm_gsubr_apply): likewise.
7762 eval.c (SCM_APPLY): likewise.
7764 * eval.c (4 places): replace scm_everr with lgh_error or
7767 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7768 scm_memory_error): new procedures.
7769 scm_everr: deleted. can use scm_wta, dropping first two args.
7770 scm_error: convert NULL subr to SCM_BOOL_F.
7772 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7775 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7778 * error.c, error.h: new error keys: scm_arg_type_key,
7779 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7781 scm_wta: reimplement using lgh_error instead of scm_everr.
7783 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7785 * gdbint.c: scm_lread now has one more argument.
7787 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7788 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7789 loading source from non-file ports, which, e. g., happens when
7790 using the Emacs interface).
7792 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7795 * read.c: Added code for recording of positions of source code
7796 expressions; New functions: recsexpr, scm_lreadrecparen;
7797 _scm_make_srcprops --> scm_make_srcprops
7798 (scm_flush_ws): Removed updating of positions counters. This work
7799 is already done by scm_gen_getc
7801 * read.h: Added prototype for scm_lreadrecparen
7803 * print.c: Added #include "alist.h"
7805 * eval.c: Added #include "hash.h"
7807 * eq.c: Added #include "ramap.h"
7809 * options.c: Documentation fixes.
7811 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7812 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7813 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7814 --> scm_make_srcprops
7816 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7817 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7818 function calls in the definition of the whash access macros.
7820 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7822 * init.c (scm_boot_guile): Add level of indirection to
7823 scm_boot_guile_1() to ensure that stack base pointer is properly
7824 initialized. There was no guarantee that variable i was the
7825 highest/lowest variable on stack (i.e. the call frame of
7826 scm_boot_guile was not completely protected from gc).
7828 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7830 * ports.h (scm_port_table): put back file_name, it will be used to
7831 support debugging. Undo related changes in fports.c, ioext.c,
7834 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7836 * ports.h (scm_port_table): remove file_name member for now, it seems
7838 * fports.c (scm_open_file): don't set file_name in PTAB.
7839 (prinfport): don't use file_name in PTAB.
7840 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7841 * ports.c (scm_add_to_port_table): don't intialize file_name.
7842 (scm_port_file_name): remove for now.
7843 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7845 * fports.h (scm_mkfile): prototype deleted.
7846 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7848 * debug.c, unif.c: use scm_out_of_range instead of
7849 wta for range errors (ASSERT still needs work).
7851 * error.c, error.h (scm_out_of_range): new procedure.
7853 * error.c, error.h (scm_out_of_range_key): new key.
7855 * posix.c (scm_sync): #else was missing.
7857 * error.c, error.h: append _key to names scm_num_overflow and
7860 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7861 of consing an empty list.
7862 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7863 of macros, saves code and string space.
7864 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7865 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7866 lower case. Rename scm_syserror_m to scm_syserror_msg.
7867 error.h: prototypes for new procedures.
7869 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7871 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7873 * error.c, error.h: setup scm_num_overflow key.
7875 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7876 Remove definition of SCM_OVSCM_FLOW.
7878 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7880 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7881 explicit message and args.
7883 * error.c, error.h, __scm.h: change system_error_sym to
7886 * error.c (system_error_sym): remove leading %% from the Scheme name
7889 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7891 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7893 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7894 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7895 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7896 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7897 renamed. (These were introduced by unsupervised name
7900 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7902 * print.c: Added code for detection of circular references during
7903 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7904 a hook for printing of closures (accessible via print options).
7905 This leads to a split of calls to scm_iprin1 into two classes:
7906 elementary print operations (e. g. the code which prints a smob)
7907 still use scm_iprin1 while top level calls (like scm_display) use
7908 scm_prin1. scm_prin1 begins by clearing the data structure used
7909 to record reference information.
7911 * print.h: Added declarations of scm_prin1 and scm_prlist.
7913 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7915 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7917 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7919 * error.c (err_head): scm_iprin1 --> scm_prin1
7921 * debug.c: Adjusted header comment.
7925 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7927 * strerror.c: Doc fix.
7929 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7931 * gdbint.c (gdb_read): Now possible to run during GC.
7932 (unmark_port, remark_port): New functions.
7934 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7936 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7937 of allocating a new string object. Also, increase size by
7938 the factor 2 instead of 1.5.
7940 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7942 * __scm.h (SCM_P): Corrected to run under traditional C.
7944 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7947 * async.c: Calls to scm_sysintern corrected.
7949 * async.h (scm_async_clock): Redundant declaration removed.
7951 * continuations.c (scm_dynthrow): Redundant declaration removed.
7953 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7954 Definition typos corrected.
7956 * debug.h: Missing declarations of functions in debug.c added
7959 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7960 Missing declarations to functions in eval.c added.
7962 * filesys.c: Possibly uninitialized variable rv.
7964 * gc.h (scm_object_addr, scm_unhash_name): Missing
7965 declarations of functions defined in gc.c added.
7967 * genio.c: Possible typos str_data -> wstr_data. ???
7969 * genio.c: Possibly unintended shadowing of local variable
7970 `int c' (gotos out of scope of inner `c'). ???
7972 * init.c: Uninitialized `SCM last' may be used.
7974 * ioext.h: (scm_sys_isatty_p): Typo.
7976 * list.h (scm_list_head): Missing prototype for function in
7979 * numbers.c (scm_two_doubles): Changed from extern to static
7980 (is used only within numbers.c).
7982 * numbers.h: Repeated declarations removed.
7984 * ports.h (scm_close_all_ports_except): Declaration for the
7985 function defined in ports.c added.
7987 * posix.h: Missing declarations added.
7989 * procs.h (scm_make_subr_opt): Missing declaration added.
7991 * socket.h (scm_sys_gethost): Missing declaration added.
7993 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7995 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7996 Missing declarations added.
7998 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
8000 * struct.c: Uninitialized variable `SCM answer' may be used.
8002 * unif.c (l2ra): Declaration prototype.
8004 * unif.c (scm_array_equal_p): Dummy definition removed (it is
8005 defined in ramap.c).
8007 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
8008 Redundant declarations removed (they are in ramap.h).
8010 * variable.h (scm_make_udvariable,
8011 scm_make_undefined_variable): Declaration corrected to
8012 correspond variable.c.
8014 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
8015 Missing declarations added.
8017 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
8019 * Makefile.in (distclean): Don't forget to delete fd.h.
8021 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
8023 * fd.h.in, tags.h: Trivial cleanups.
8025 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
8026 marksweep.h just declared functions from gc.c.
8027 * gc.h, libguile.h: Don't #include "marksweep.h".
8028 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8029 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
8030 dependencies updated.
8032 * libguile.h: Don't #include "files.h"; it's been deleted.
8034 * files.c (scm_sys_delete_file): Moved to filesys.c.
8035 File is now empty; deleted.
8037 * filesys.c: scm_sys_delete_file is now here. Remove
8038 #if's; they seem to rely on remnants of an old portability
8039 regimen. If the problems come up again, solve them properly,
8040 using autoconf. Specifically: Don't test M_SYSV, and #define
8041 remove to be unlink if it's #defined; don't use remove just
8042 because HAVE_STDC_HEADERS is #defined.
8043 * filesys.h: Add declarations for scm_sys_delete_file.
8044 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8045 files.o, files.h, files.c, and files.x.
8046 * init.c: Don't #include "files.h", and don't call scm_init_files.
8048 Use SCM_P instead of PROTO; the latter intrudes on the user's
8050 * params.h: Deleted; definition of SCM_P moved to...
8051 * __scm.h: ... here, where it replaces PROTO macro.
8052 * libguile.h, smob.h: Don't #include "params.h".
8053 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
8054 smob.h: Fix prototypes accordingly.
8055 * Makefile.in: Update dependencies.
8056 (inner_h_files): Remove params.h.
8058 * gc.c: #include "gc.h"; every module should include its header,
8059 to let the compiler cross-check the declarations against the
8062 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
8063 simpos.h: #include "libguile/__scm.h".
8065 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
8067 * init.c: Don't forget to #include smob.h and init.h.
8068 * Makefile.in: Dependencies updated.
8070 * smob.h: Use PROTO instead of #if __STDC__.
8072 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
8074 * __scm.h: Doc fixes.
8076 * __scm.h, libguile.h: Use "quotes" in the #includes, not
8077 <angles>; this allows `make depends' to work properly.
8079 * libguile.h: #include smob.h and pairs.h before the others; they
8080 define typedefs used by other headers.
8082 C files should #include only the header files they need, not
8083 libguile.h (which #includes all the header files); the pointless
8084 recompilation was wasting my time.
8085 * Makefile.in (all .o dependency lists): Regenerated.
8086 * libguile.h: Don't try to get a definition for size_t here...
8087 * __scm.h: Do it here.
8088 * _scm.h: Since this is the internal libguile header, put things
8089 here that all (or a majority) of the libguile files will want.
8090 Don't #include <libguile.h> here; that generates dependencies on
8091 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
8092 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
8093 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

8190 * weaks.c: Get "weaks.h".
8192 * stackchk.h: #include "libguile/debug.h",
8194 * print.h, read.h: #include "options.h", since everyone who uses
8195 either of these files will need that.
8197 * smob.h: #include "ports.h", "genio.h", and "print.h", since
8198 anyone who uses this file will need them to define the smob
8199 printing functions. Also, get markers.h, since people will need
8200 to #define the mark functions.
8202 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
8203 * ports.h: ... to here.
8205 * ports.h (scm_port_table_size): Explicitly give type as 'int';
8206 don't rely on archaic C default type rules.
8208 * fports.h: #include "libguile/ports.h", since you need that in
8209 order to parse this.
8211 * genio.h: #include "libguile/print.h", because you need that to
8212 parse this; don't bother #including "ports.h", since print.h gets
8215 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
8217 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
8218 this; it's now a reference to an element of *scm_root.
8220 * debug.h: Don't #include "options.h"; the compiler won't be able
8221 to find that once the headers are installed; instead, #include
8222 "libguile/options.h".
8223 * gc.h: Same, with marksweep.h.
8224 * mbstrings.h: Same, with symbols.h.
8225 * scmhob.h: Same, with _scm.h.
8226 * smob.h: Same, with params.h.
8228 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
8229 C files; there's no need for this, and it forces recompilations
8232 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
8234 * error.c (scm_error): declare scm_error_callback.
8236 * error.h: prototype for scm_error_callback.
8238 * __scm.h: define lgh_error.
8239 (SCM_SYSERROR): redefine using lgh_error.
8241 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
8243 * error.c (scm_error): new procedure.
8245 * error.h: prototype for scm_error.
8247 * Makefile.in (install): install scmconfig.h from the current
8248 directory, not $(srcdir).
8250 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8252 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8253 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8254 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

8260 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8261 vports.h, weaks.h: #include "libguile/__scm.h", not
8262 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
8263 dependencies are within libguile properly.
8265 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8267 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8268 when scmconfig.h doesn't exist.
8270 * load.c (scm_sys_try_load): Correct spelling.
8272 * feature.c (scm_loc_features): Make this static.
8274 * Makefile.in (libpath.h): Omit trailing slash from path. We
8275 shouldn't require it of users, so why put it here?
8277 Move code to initialize and search %load-path from ice-9 to C
8278 code, so we can use the load-path to find the ice-9 boot code;
8279 this makes it easier to run Guile without installing it. See
8280 corresponding changes in guile/Makefile.in.
8281 * feature.c: Move stuff concerned with the load path to load.c.
8282 (scm_compiled_library_path): Deleted.
8283 Don't #include libpath.h here.
8284 * feature.h: Don't mention scm_compiled_library_path.
8285 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8286 <sys/stat.h>, and <unistd.h> (if present).
8287 (R_OK): #define if the system hasn't deigned to.
8288 (scm_loc_load_path): New variable.
8289 (scm_init_load_path, scm_sys_search_load_path,
8290 scm_sys_try_load_path): New functions.
8291 (scm_init_load): Initialize scm_loc_load_path to point to the
8292 value cell of the Scheme %load-path variable.
8293 * load.h: Add declarations for scm_sys_search_load_path,
8294 scm_sys_try_load_path.
8295 * init.c: Call scm_init_load_path.
8296 * Makefile.in (feature.o, load.o): Dependencies updated.
8298 * load.c, load.h: Rewrite using PROTO macro.
8300 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8302 * gc.c (scm_cellp): New function: C predicate to determine if an
8303 SCM value can be regarded as a pointer to a cell on the heap.
8305 * gc.h: Added declaration of scm_cellp.
8307 * gdb_interface.h: New file: The GDB interface header from the GDB
8310 * gdbint.c: New file: GDB interface.
8312 * gdbint.h: New file: GDB interface.
8314 * libguile.h: Added #include <libguile/gdbint.h>.
8316 * init.c (scm_boot_guile): Added scm_init_gdbint.
8318 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8319 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8320 found if object files and source are kept separate).
8322 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8324 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8326 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8328 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8329 TK_SRC_DIR; they're not relevant any more.
8331 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8332 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8334 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8336 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8337 search path, so we can find the <libguile/MUMBLE.h> headers.
8339 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8341 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8342 implicit in the .c.o rule.
8343 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8346 Put the library path in a header file, instead of passing it on
8347 the command line in every compilation.
8348 * Makefile.in (libpath.h): New target.
8349 (feature.o): Depend on libpath.h.
8350 (clean): Delete libpath.h.
8351 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8352 * feature.c: ... #include "libpath.h" here.
8353 * .cvsignore: Ignore libpath.h.
8355 Don't install the unwashed masses of Guile header files in the
8356 main #include path; put most of them in a subdirectory called
8357 'libguile'. This avoids naming conflicts between Guile header
8358 files and system header files (of which there were a few).
8359 * Makefile.in (pkgincludedir): Deleted.
8360 (innerincludedir): New variable; this and $(includedir) are enough.
8361 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8362 (installed_h_files): Divide this up. Now this variable lists
8363 those header files which should go into $(includedir) (i.e. appear
8364 directly in the #include path), and ...
8365 (inner_h_files): ... this new variable says which files appear in
8366 a subdirectory, and are referred to as <libguile/mumble.h>.
8367 (h_files): List them both.
8368 (install): Create innerincludedir, not pkgincludedir. Put
8369 the installed_h_files and inner_h_files in their proper places.
8370 (uninstall): Corresponding changes.
8371 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8372 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8373 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8374 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8375 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8376 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8377 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8378 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8379 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8380 vports.h, weaks.h: Find __scm.h in its new location.
8381 * __scm.h: Find scmconfig.h and tags.h in their new locations
8382 (they're both "inner" files).
8384 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8386 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8388 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8390 * posix.c: Doc fixes.
8392 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8394 * socket.c: Don't include a prototype for inet_aton; just use a
8395 K&R style declaration, to avoid warnings but minimize the chance
8396 of conflicts with the system.
8398 On NextStep, <utime.h> doesn't define struct utime, unless we
8399 #define _POSIX_SOURCE before #including it.
8400 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8401 * acconfig.h: New comment text for above CPP symbol.
8402 * configure.in: Call it.
8403 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8405 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8407 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8408 testing for __EMX__.
8410 * posix.c: #include <libc.h>, if it exists.
8412 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8413 don't even know if the latter exists.
8415 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8416 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8417 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8419 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8421 (scm_init_posix): Use them when initializing the Scheme constants
8424 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8426 * Makefile.in (libdir, includedir, bindir): Use the
8427 autoconf-supplied values, instead of deriving them ourselves.
8428 (pkgincludedir, datadir, pkgdatadir): New variables.
8429 (install, uninstall): Put the header files in a special
8430 subdirectory, not in the main search path.
8432 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8433 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8435 * Makefile.in (IMPLPATH): Deleted; never used.
8437 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8438 on the Tcl/Tk source any more.
8439 (INCLUDE_CFLAGS): Remove references to the above.
8441 * Makefile.in (version.o): Corrected dependencies.
8443 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8445 * libguile.h: #include "version.h"
8447 * init.c (scm_boot_guile): Call scm_init_version.
8448 * gscm.c (gscm_run_scm): Call scm_init_version.
8450 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8451 GUILE_VERSION): AC_DEFINE these.
8452 (acconfig.h): #undef the above symbols.
8454 * Makefile.in (libobjs): Add version.o.
8455 (installed_h_files): Add version.h.
8456 (c_files): Add version.c.
8457 (gen_c_files): Add version.x.
8458 (version.o): New rule.
8459 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8460 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
8461 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,

8463 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
8464 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
8465 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
8466 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
8467 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
8468 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
8469 weaks.o): Add version.h to dependency lists.
8470 (markers.o): Remove duplicate rule.
8472 * version.h: New file.
8474 * version.c: New file.
8476 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8478 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8479 array; use it appropriately. Since GCC is quite happy to
8480 subscript functions, it never warned us about this; we should use
8481 -Wpointer-arith in the future. I guess we never tested
8484 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8486 * socket.c: Doc and copyright fixes.
8488 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8490 * debug.c: Fixed and improved gdb support.
8492 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8494 * socket.c: Added declaration of inet_aton to avoid compiler
8495 warning. (Hope this solution is correct.)
8497 * stime.c: Added declaration of ftime. (This is missing in
8500 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8502 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8504 * Makefile.in (c_files): add strerror.c.
8506 * strerror.c: new file from Emacs' sysdep.c.
8507 maybe configure should also check for sys_errlist.
8509 * configure.in (AC_REPLACE_FUNCS): add strerror.
8511 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8513 * debug.c (scm_init_debug): Added initialization for
8514 scm_evaluator_traps.
8516 * debug.h, debug.c: Various name changes.
8517 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8518 "debug-options-interface". See commentary in options.c.
8520 * options.h, options.c: Options now have documentation strings.
8521 Also added a long explanatory commentary.
8523 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8526 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8527 last_debug_info_frame is now updated in all cases.
8529 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8532 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8534 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8535 Added option STACK_CHECKING.
8537 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8539 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8541 * __scm.h: Removed symbols for debugging support.
8543 * acconfig.h: Added symbols for debugging support.
8545 * configure.in: Added user option for debugging support.
8546 --enable-debug will include the debugging code into libguile.a.
8548 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8549 scm_relocate_chunk_to_heap.
8551 * debug.c: New file: low-level debugging support. It also
8552 includes support for debugging with gdb. (The extensions to gdb
8553 are written by Per Bothner at Cygnus.)
8555 * debug.h: New file: low-level debugging support.
8557 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8558 argument pairs. Extensive modifications to the debugging
8559 evaluator. Added "SECTION:" commentaries to clarify what happens
8560 when, during double compilation. Renamed EVALIMP --> EVALIM.
8561 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8562 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8563 the beginning of the file. New procedure: scm_unmemocopy.
8564 Added some global state variables needed by the debugging
8565 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8566 check_entry, check_apply, check_exit, debug_options and
8567 evaluator_traps. New acro: undefine.
8569 * eval.h: Renamed EVAL --> XEVAL.
8571 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8572 --> scm_make_weak_key_hash_table.
8574 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8575 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8577 * libguile.h: Conditionally include debug.h
8579 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8580 scm_object_properties shouldn't return handle. `handle' now gets
8581 initialized in scm_set_object_properties_x. scm_object_properties
8582 doesn't any longer create an entry in scm_object_whash.
8584 * options.c: New file: handling of run time options.
8586 * options.h: New file: handling of run time options.
8588 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
8590 * print.c: New procedure: scm_print_options
8592 * print.h: Defines for print options.
8594 * read.c: New procedure: scm_read_options
8596 * read.h: Defines for reader options.
8598 * root.h: Added scm_source_whash among scm_sys_protects.
8600 * srcprop.c: New file: source properties.
8602 * srcprop.h: New file: source properties.
8604 * throw.c (jbsmob): Jump buffers are now correctly allocated.
8605 (Bug found by A. Green.)
8607 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8609 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8611 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8613 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8615 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8616 and should be called by the final client.
8618 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8620 * gc.h: Use the PROTO macro when declaring functions.
8621 * gc.c: Use the PROTO macro when declaring static functions.
8622 Remove the CPP hair around function definitions.
8624 * gc.c (scm_init_storage): Initialize scm_asyncs.
8626 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8627 preprocessor symbol; "__scm.h" is where it might get #defined.
8628 * __scm.h: Similar: #include <scmconfig.h> before testing
8631 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8633 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8635 * init.c (scm_boot_guile): Add init_func argument; call
8636 (*init_func) instead of calling scm_appinit; it's ucky to
8637 hard-code names for the user's procedures.
8638 * init.h (scm_boot_guile): Adjust declaration.
8640 * __scm.h (PROTO): New macro, for declaring functions with
8643 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8644 eliminate all the __STDC__ conditionals.
8645 (scm_boot_guile): Add declaration.
8646 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8647 Remove __STDC__ conditionals around function definitions; the
8648 declarations in init.h will provide the same information, more
8651 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8652 complain about it in the error message; the error message is
8653 adequate without that note, and there's nothing the user can do
8656 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8658 * Makefile.in (ancillary): Drop def.sed.
8660 * posix.c (scm_init_posix): Use numeric values, rather than
8661 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8662 F_OK. The symbols aren't available on some systems, and I'm
8663 pretty sure their values are fixed by common widespread practice.
8664 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8666 More functions unavailable on some systems.
8667 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8668 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8670 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8671 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8672 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8673 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8674 stub that signals an error as the #else.
8676 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8678 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8680 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8682 * unif.c: include ramap.h.
8684 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8686 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8688 * ports.c: include sys/ioctl.h.
8690 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8692 * configure.in: check for sys/ioctl.h.
8694 * ports.c: include <malloc.h> not "malloc.h".
8696 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8698 * fports.c: remove ttyname and tmpnam declarations.
8700 * posix.c: fewer ttyname declarations.
8702 * fports.c: include <string.h> not "string.h".
8704 * init.c, ioext.c: include string.h and unistd.h.
8706 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8708 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8709 genio.c, simpos.c, vports.c: include string.h.
8711 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8713 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8715 (scm_addr_buffer_size): change type from scm_sizet to int.
8716 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8717 from scm_sizet to int.
8719 * error.c: include unistd.h.
8721 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8724 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8726 * __scm.hd, def.sed: deleted.
8728 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8730 Changes for NeXT, suggested by Robert Brown.
8731 * configure.in: Call AC_TYPE_MODE_T.
8732 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8733 NeXT. Put header file list in alphabetical order.
8734 * configure, scmconfig.h.in: Regenerated.
8735 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8737 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8740 * acconfig.h: New file, providing documentation for the CPP
8741 symbols defined in configure.in
8742 * acconfig-1.5.h: Removed; superceded by the above.
8744 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8746 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8748 * fports.c (scm_open_file): don't return #f, throw error.
8750 * ioext.c (fileno): renamed from %fileno.
8751 (soft-fileno): deleted.
8753 * ports.c (scm_port_revealed): don't need to check for -1 from
8755 (scm_set_port_revealed_x): return unspecified, not #f.
8757 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8759 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8761 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8763 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8765 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8767 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8768 This is necessary on Ultrix, and doesn't hurt portability.
8770 * Makefile.in (dist-dir): New target, implementing a new dist system.
8771 (installed_h_files): Put in alphabetical order.
8772 Remove duplicate entries for markers.h and unif.h.
8773 (c_files): Remove duplicate entries for markers.c.
8774 (ancillary): Renamed from anillery; all uses changed. Remove
8775 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8776 Remove all the ../doc/* files; doc/Makefile.in handles that.
8778 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8780 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8781 every if must have an else, or else the whole command has a

8853 * gscm.h: gscm_mkarray eliminated (presumably was not being used

8871 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8872 handled correctly (SCM_FREEP was applied to them) -- test for

9041 initialization to fix a race condition.
9043 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

9070 The weird symbol syntax is also a bit bogus (emacs doesn't quite
