7 Mon Sep 27 17:15:14 1999 Greg J. Badros <gjb@cs.washington.edu>
9 * __scm.h: Fix a bunch of macros that were missing do-while(0)
12 * debug.c, eval.c: Fix buggy uses of SCM_ALLOW_INTS (missing
13 semicolon) exposed by the above change.
15 1999-09-27 Greg J. Badros <gjb@cs.washington.edu>
17 * stacks.c: Avoid compiler warning re: unitialized var.
19 * scmconfig.h.in: Added DEBUG_FREELIST
21 * pairs.h: Fix macro that was not do-while(0) sandwiched.
23 * gc.h, gc.c: Added scm_gc_set_debug_check_freelist_x,
26 1999-09-23 Gary Houston <ghouston@freewire.co.uk>
28 * ioext.c (scm_init_ioext): enable "i/o-extensions" feature here
29 instead of in scm_init_filesys.
31 * init.c (scm_boot_guile_1): don't call scm_init_posix or
32 scm_init_filesys unless HAVE_POSIX is defined.
33 don't call scm_init_netdb or scm_init_socket unless
34 HAVE_NETWORKING is defined.
36 * Makefile.am (EXTRA_libguile_la_SOURCES): filesys.c, posix.c,
37 net_db.c, socket.c: moved here from libguile_la_SOURCES.
39 1999-09-25 Jim Blandy <jimb@savonarola.red-bean.com>
41 * root.c (scm_make_root): Initialize all the fields of the new
42 root. GC could happen any time, you know. (Thanks to Greg
45 * numbers.c (scm_number_to_string): Signal an error if radix is
46 less than two. (Thanks to Jorgen Schaefer.)
48 * Makefile.am (EXTRA_libguile_la_SOURCES): Add memmove.c here,
49 so automake will actually generate rules for it.
50 * Makefile.in: Regenerated.
52 1999-09-21 Jim Blandy <jimb@savonarola.red-bean.com>
54 * backtrace.c: #include "_scm.h" before testing whether
55 HAVE_UNISTD_H is #defined.
57 1999-09-20 Jim Blandy <jimb@savonarola.red-bean.com>
59 * read.c (scm_read): Don't assume that scm_cur_inp is always open.
60 * ports.c (scm_read_char): Same.
61 * ioext.c (scm_read_line): Same.
62 (Thanks to Bernard Urban.)
64 1999-09-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
66 * vectors.c (scm_vector_move_right_x): Bugfix: Remove side effect
68 numbers.c: Removed #ifndef SCM_RECKLESS at places where type
69 checking may invoke a generic. (Thanks to Michael Livshin.)
71 * __scm.h (SCM_WTA_DISPATCH_0, SCM_GASSERT0): New macros.
73 * numbers.c (scm_max, scm_min, scm_sum, scm_difference,
74 scm_product, scm_divide): Bugfix: Don't pass SCM_UNDEFINED to the
75 generic function if the asubr is called with only one arg.
77 1999-09-20 Gary Houston <ghouston@freewire.co.uk>
79 * scmsigs.c (scm_sigaction): add SA_RESTART to flags only if
80 HAVE_RESTARTABLE_SYSCALLS.
81 (scm_init_scmsigs): use siginterrupt if it's available. not
82 everyone who has restartable syscalls has SA_RESTART it seems.
84 (scm_sigaction): use scm_num2long/scm_long2num when converting
85 SIG_DFL/SIG_IGN, in case it doesn't fit in an INUM. use
86 scm_integer_p to test the type.
88 1999-09-18 Gary Houston <ghouston@freewire.co.uk>
90 * _scm.h, scmsigs.c: replace HAVE_RESTARTS with
91 HAVE_RESTARTABLE_SYSCALLS.
93 * strports.c (scm_strport_to_string): create the string from
94 pt->read_buf instead of an expression that evaluates to the
97 * gdbint.c (gdb_print): don't just use SCM_CHARS to get a C string
98 from the port: the port's buffer may not be NUL terminated.
100 1999-09-16 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
102 * Makefile.am (.c.x): Added missing semicolon after `false'.
104 1999-09-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
106 * print.c (scm_iprin1): Turn `write' and `display' into
107 primitive generics and use their associated generic functions in
108 scm_iprin1 for GOOPS objects.
110 * backtrace.c: #include <unistd.h> if present.
112 1999-09-14 Jim Blandy <jimb@savonarola.red-bean.com>
114 * Makefile.am (.c.x): Don't create a subshell just to delete the
115 .x file and return false.
116 * Makefile.in: Regenerated.
118 1999-09-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
120 * feature.c (scm_create_hook): New function. Replaces
121 scm_make_named_hook which is now deprecated.
122 (scm_make_hook_with_name): New primitive.
123 (print_hook): Hooks now print in a fancy way.
125 1999-09-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
127 * __scm.h, backtrace.c, backtrace.h, debug.c, debug.h, dynl-dld.c,
128 dynwind.c, dynwind.h, eval.h, evalext.c, evalext.h, feature.c,
129 feature.h, hashtab.c, hashtab.h, objects.c, objects.h, print.c,
130 procs.c, procs.h, smob.c, smob.h, srcprop.c, strorder.c, struct.c,
131 struct.h: Updated copyright notices.
133 * srcprop.c (scm_source_property): Bugfix: Use SCM_NECONSP instead
134 of SCM_NCONSP. (Thanks to Greg Badros.)
136 * gsubr.c (scm_make_gsubr): Use scm_make_subr_opt for creation of
139 * eval.c, debug.h (SCM_BACKTRACE_WIDTH): New debug option: width.
141 * backtrace.c: Keep backtraces within specified width by
142 adaptively adjusting fancy printing parameters and cut output if
144 (scm_display_application): Check args.
146 1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
148 Change the name of the objects returned by OPENDIR from
149 "directory" to "directory stream". A predicate named "directory?"
151 * filesys.c (scm_directory_stream_p): Renamed from scm_directory_p.
152 At the Scheme level, "directory?" -> "directory-stream?".
153 (scm_dir_print): Use the phrase "directory stream" in printed form.
154 * filesys.h (scm_directory_stream_p): Prototype renamed
157 * Makefile.am (CLEANFILES): Remove versiondat.h; that should only
158 be removed by `make distclean', since it's generated by configure.
159 * Makefile.in: Regenerated.
160 (Thanks to Robert Bihlmeyer.)
162 * strop.c (scm_substring_move_x): Signal an error if start1
163 doesn't come before end1. (Thanks to Karoly Lorentey).
165 * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
166 calling SCM_NIMP. (Thanks to Karoly Lorentey).
168 * version.c (scm_libguile_config_stamp): Deleted. See
169 corresponding change to ../ice-9/boot-9.scm.
170 * versiondat.h.in: Remove definition for GUILE_STAMP.
171 * version.h: Delete prototype.
172 * Makefile.in: Regenerated.
174 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
176 * filesys.c (scm_directory_p): new procedure "directory?" Returns
177 a boolean indicating whether its argument is a directory
178 port as returned by opendir (thanks to Dirk Herrmann for the
181 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
183 * backtrace.c (display_frame_expr): Don't print a newline.
184 (display_frame): Print the newline here instead.
185 (display_backtrace_body): Don't print "Backtrace:".
186 (scm_backtrace): Print "Backtrace:" here instead.
188 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
190 * procs.c (scm_setter): Signal WTA if handed an entity or operator
193 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
194 primitives. (Thanks to Greg Badros);
195 (scm_hook_to_list): New primitive; Hooks are now smobs.
197 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
199 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
200 of #f for the 10th vector element to avoid an exception
201 seen by Bernard Urban.
202 (scm_mktime): unneeded ASSERT removed.
204 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
206 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
209 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
211 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
213 * numbers.c: Converted comparison operations to dispatch on
214 generic if args don't match.
216 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
218 1999-09-06 James Blandy <jimb@mule.m17n.org>
220 * guile-snarf.c: Deleted. Snarfing should respect CPP
221 conditionals, so it needs to actually run CPP. Bleah.
223 1999-09-05 James Blandy <jimb@mule.m17n.org>
225 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
226 * guile-snarf.in: Be sure to exit with an error if CPP does.
227 * Makefile.am (.c.x): Delete the .x file and exit with an error
228 status if guile-snarf exits with an error status.
229 * Makefile.in: Regenerated.
231 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
232 scm_makekey, which doesn't exist any more. Guess nobody's using
235 * guile-snarf.c: New implementation of guile-snarf, meant to be
236 more robust than the shell script. I think it's complete, but I
237 haven't tested it at all, and I haven't changed the build process
238 to actually use it. We should compare its output against that of
239 the existing shell script, for all source files.
241 * guile-snarf.c (parse_args): Abort if we haven't handled some
244 1999-09-03 James Blandy <jimb@mule.m17n.org>
246 * load.c (scm_search_path): If the filename has any extension at
247 all, ignore the entire list of extensions. Also, don't check whether
248 the file is accessible. If the file exists, accessible or not, we
249 should return it. Inaccessible files should cause an error later.
250 (Thanks to Keisuke Nishida for the suggestions.)
252 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
254 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
255 atexit not available. (sunos4.1.4 needs it.)
257 1999-09-01 James Blandy <jimb@mule.m17n.org>
259 I take it all back --- bcopy does handle overlapping source and
260 destination areas correctly. At least on every system I could
261 find. But it is better to use AC_REPLACE_FUNCS than to introduce
262 new CPP conditionals.
263 * memmove.c: New file, implementing memmove in terms of bcopy.
264 * scmconfig.h.in: Regenerated.
266 Allocators should use the `void *' type for generic pointers.
267 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
268 argument and return types.
269 * gc.h: Corresponding changes to prototypes.
272 1999-08-31 James Blandy <jimb@mule.m17n.org>
274 * numbers.c (scm_init_numbers): Claim to support the `complex'
275 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
277 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
278 find (ice-9 boot-9) when Guile was compiled in a separate
279 directory from the source. (Thanks to Rodney Brown.)
280 * Makefile.in: Regenerated.
282 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
283 table lengths by the size of a single element when growing the
284 table. (Thanks to Bill Schottstaedt.)
286 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
288 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
289 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
290 since that cuts down the time for type dispatch by 50%.
292 1999-08-30 James Blandy <jimb@mule.m17n.org>
294 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
295 not a correct substitute for memmove, because it doesn't handle
296 overlapping source and destination areas on many platforms.
297 Overlaps are the primary reason to use memmove in the first place.
298 * ports.c (scm_ungetc): Same.
299 * strop.c (scm_substring_move_x): Same.
301 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
303 * gc.c (scm_init_storage): Skip registration of cleanup on systems
304 which lack atexit. (Is it important that cleanup is made
305 properly? Maybe we should replace all `exit' with `scm_exit' and
308 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
309 scm_struct_free_standard, scm_struct_free_entity): Declared to
310 return scm_sizet instead of size_t.
312 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
313 there on sunos4.1.4.)
315 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
317 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
318 Account for the case when second argument is unbound.
320 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
321 (Thanks to Karoly Lorentey.)
323 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
324 isn't present. (Thanks to Suzuki Toshiya.)
326 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
329 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
332 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
333 Bernard Urban and Ian Grant.)
335 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
336 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
337 change in the representation of entities and operators.)
339 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
341 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
342 don't allocate zero bytes (thanks to Bill Schottstaedt).
344 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
346 * procs.c (scm_setter): Converted to use generic dispatch.
348 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
351 * load.c (scm_search_path): Don't try extensions which already are
352 present at the end of the filename.
353 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
355 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
357 Cleanup and simplification of generic method dispatch.
358 Also, the quadruple representation of entity and operator
359 procedures has been replaced with single.
361 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
363 * print.c (scm_isymnames): Removed #@hash-dispatch.
365 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
366 from eval.c; Support 0 arity methods.
367 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
368 (scm_apply_generic_env): Removed.
369 Replaced slots proc0-3 with procedure.
371 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
372 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
373 SCM_OPERATOR_PROCEDURE.
374 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
375 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
377 * struct.c, struct.h: Replace 4 procedure slots with one.
378 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
380 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
383 * eval.c (scm_sym_args): Removed.
384 (SCM_CEVAL): Simplified entity application.
385 Moved dispatch code to objects.c.
387 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
389 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
391 * sort.c (closureless): Use scm_eval_body.
393 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
394 with a symbol as last form was first called normally and then via
395 `map' or some other mechanism using primitive apply, an ILOC was
398 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
400 This change extends the representation of primitive procedures
401 with more data fields, e.g. a place for documentation and true
402 procedure properties.
404 * procs.c, procs.h (scm_subr_entry): New type: Stores data
405 associated with subrs.
406 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
407 SCM_SUBR_DOC): New macros.
408 (scm_subr_table): New variable.
409 (scm_mark_subr_table): New function.
411 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
413 * gc.c (scm_gc_mark): Don't mark subr names here.
414 (scm_igc): Call scm_mark_subr_table.
417 This change implements a scheme for letting a generic work as a
418 shadow for a primitive procedure. If the primitive procedure
419 can't dispatch on its arguments, control is left over to the
420 generic. Normal wrong type arg errors will be generated until the
421 user has hung the first method on the primitive.
423 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
425 * procs.c, procs.h (scm_subr_p): New function (used internally).
427 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
429 * objects.c, objects.h (scm_primitive_generic): New class.
431 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
433 * print.c (scm_iprin1): Print primitive-generics.
435 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
436 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
438 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
439 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
440 primitives). NOTE: This means that it is now *required* to use
441 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
442 obscured representation that will be removed in the future anyway,
443 so backward compatibility is no problem here).
445 * numbers.c: Converted most numeric primitives (all but bit
446 comparison operations and bit operations) to dispatch on generic
450 Better support for applying generic functions.
452 * eval.c, eval.h (scm_eval_body): New function.
454 * objects.c (scm_call_generic_0, scm_call_generic_1,
455 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
459 Optimization of the generic function dispatch mechanism.
461 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
462 called scm_memoize_method instead of doing a second lookup.
464 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
469 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
470 scm_sysintern so that the binding connected with the subr name
471 isn't cleared when we give set = 0.
474 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
476 More transparent handling of ports with print states.
478 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
479 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
480 instead of a pair of a port and a print state. We'll need to cons
481 once extra in scm_printer_apply but the type system will be
482 cleaner, it will mix better with GOOPS, and, it will be even more
483 transparent to the user.
485 * print.c (scm_get_print_state): New procedure: Given an output
486 port, return the print state associated to it in the current print
487 chain, if one exists;
488 (scm_port_with_print_state): New procedure: Associate a
489 print-state with a port.
490 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
491 (scm_printer_apply): Wrap port and pstate as a smob;
492 (print_state_printer): Removed.
494 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
496 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
499 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
500 testing (otherwise the port-print-state trick won't be transparent
501 to the user; one example where this caused problems was in the
502 (ice-9 format) module).
504 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
506 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
507 SCM_UNSPECIFIED instead of the set value.
509 1999-08-20 James Blandy <jimb@mule.m17n.org>
511 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
513 * ports.h (enum scm_port_rw_active): New enum, containing
514 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
515 zero). The debugger knows about enums, but doesn't know about
517 (typedef scm_port): Declare rw_active member to be an enum
519 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
521 * ports.c (scm_add_to_port_table): Same.
522 * strports.c (st_flush, st_end_input): Same.
524 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
525 scm_must_realloc, and scm_done_malloc as appropriate.
527 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
529 * sort.c (quicksort): Added condition to protect the algorithm
530 from crashing the interpreter if the less predicate is buggy.
532 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
534 * fports.c (fport_write): fix line-buffering mode again.
535 (scm_open_file): recognise 'l' for line-buffering.
536 (scm_setvbuf): recognise _IOLBF for line-buffering.
538 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
540 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
543 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
546 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
548 * fports.c (fport_write): use memcpy instead of strncpy, in case
549 the data contains NUL.
551 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
553 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
555 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
556 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
557 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
558 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
559 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
560 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
561 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
562 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
563 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
564 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
565 scm_sym_ as prefix for symbols.
567 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
569 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
570 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
571 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
572 scm_sym_atcall_cc): Made global.
574 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
576 * eval.c (scm_sym_args): Made global.
578 * objects.c (scm_set_object_procedure_x): Disallow setting of
579 procedures for pure generic functions.
581 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
583 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
584 Scheme name from lseek to seek, but lseek was added recently so
585 it shouldn't be a big problem.
586 * ports.c, gdbint.c, ioext.c: changed callers.
588 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
590 * fports.c (fport_input_waiting): if select is used, return 1
591 instead of whatever FD_ISSET expands to. maybe it will be useful
592 to interpret the value from the input_waiting ptob procedure as a
593 lower bound on the number of bytes available.
595 * Mikael asked for a few names to be changed...
597 * ports.c (scm_make_port_type): take the write procedure as the
598 second argument instead of the flush procedure.
599 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
600 fflush -> flush, read_flush -> end_input, fclose -> close,
601 fill_buffer -> fill_input, ftruncate -> truncate,
602 input_waiting_p -> input_waiting.
604 * ports.c (end_input_void_port): was read_flush_void_port.
605 (scm_set_port_end_input): was scm_set_port_flush_input.
606 (scm_set_port_flush): was scm_set_port_write.
607 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
608 (scm_end_input): was scm_read_flush.
609 (scm_fill_input): was scm_fill_buffer.
610 (scm_flush): was scm_fflush.
611 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
612 (fport_end_input): was local_read_flush.
613 (fport_flush): was local_fflush.
614 (fport_close): was local_fclose.
615 (fport_truncate): was local_ftruncate.
616 (fport_seek): was local_seek.
617 (fport_free): was local_free.
618 (fport_fill_input): was fport_fill_buffer.
619 * strports.c (st_end_input): was st_read_flush.
620 (st_truncate): was st_ftruncate.
621 * vports.c: (sf_flush): was sfflush.
622 (sf_close): was sfclose.
623 (sf_fill_input): was sf_fill_buffer.
625 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
628 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
630 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
631 forms now contain the expressions to be dispatched upon instead of
632 depending on a surrounding lambda or let; Generic function
633 dispatch has been optimized; `apply' on a generic function now
634 works a little bit strangely. It uses a trick so that the type
635 dispatch code in SCM_CEVAL can be reused.
637 * objects.h, objects.c (scm_apply_generic_env): Added (used by
639 (scm_operator_p): Added.
640 (scm_sym_atdispatch): Added.
641 (scm_set_object_procedure_x): Modified to handle the new style
643 (scm_object_procedures): New debugging procedure.
645 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
647 * eval.c, eval.h (scm_sym_args): Added.
649 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
651 * feature.c, feature.h (scm_c_run_hook): Added.
653 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
654 cdrxnoap and loopnoap instead of begin and loop.
656 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
658 * ports.c (scm_putc, scm_puts),
659 * unif.c (scm_uniform_array_write): use scm_lfwrite.
660 * ports.c (scm_putc): change type of first argument from int to char.
662 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
664 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
665 SCM_IM_HASH_DISPATCH.
667 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
668 (scm_si_redfined, scm_si_hashsets): Moved.
670 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
671 flag which combines type and status info so that the class
672 redefinition protocol has zero cost during normal execution.
674 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
676 * ports.h (scm_ptob_descriptor): include a write procedure again.
677 it's more efficient for unbuffered fports (e.g., sockets.)
679 * ports.c (scm_puts): use ptob->write.
680 * vports.c (scm_make_sfptob): set write proc in ptob.
681 * strports.c (scm_make_stptob): set write proc in ptob.
682 * ports.c (write_void_port): new procedure.
683 * vports.c (sf_write): new procedure.
684 * ports.c (scm_lfwrite): use ptob->write.
685 * strports.c (st_write): new procedure.
686 * fports.c (fport_write): new procedure.
687 (scm_make_fptob): set write in ptob to fport_write.
688 * ports.h: prototype for scm_set_port_write.
689 * ports.c (scm_make_port_type): initialise ptob write procedure.
690 (scm_set_port_write): new proc.
692 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
694 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
695 until we've verified that it is actually a port. (Thanks to
698 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
700 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
701 code, particularly an unnecessary test (len != size, where len ==
702 size). (Was this leftovers from debugging code, or have I missed
705 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
706 size. (Thanks to James Dean Palmer.)
708 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
709 (Thanks to Lorentey Karoly.)
711 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
713 * eval.c (scm_m_expand_body): Use scm_cons_source.
715 * struct.c (scm_print_struct): Use vtable name.
717 * print.c (scm_init_print): Set name of print state type.
719 * stacks.c (scm_init_stacks): Set name of stack type.
721 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
723 * eval.c (SCM_CEVAL): Removed old implementation of internal
726 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
728 * debug.c, debug.h (scm_reverse_lookup): Added.
729 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
730 internal procedure definitions; Don't use scm_i_inner_name.
732 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
735 * eval.h: Added prototypes for multi language support functions.
737 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
738 improper lists in the low-level representation, since that will
739 cause a begin to be prepended at macro expansion.
741 * eval.c (scm_cons_source): Version of cons which copies source
742 properties from an existing cell.
743 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
745 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
746 procedure source before calling scm_unmemocopy instead of faking
749 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
751 Ported `internal defines' fix from SCM. Original ChangeLog entry:
753 1998-07-09 Radey Shouman <radey@colorage.com>
755 * eval.c (ceval_1): Modifications to allow rewriting of interal
756 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
757 body of which it is the CAR is macro expanded by m_expand_body,
758 which rewrites internal DEFINE.
760 (m_expand_body): Added.
762 (m_macroexp1): Added argument to control error checking:
763 m_expand_body may speculatively expand forms in the wrong
764 environments. Made argument number checks conditional on
767 (m_body): Added, error checks bodies and inserts the ISYM tokens.
769 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
772 (m_cond): (m_case): (m_quote): Modified to avoid destructively
773 changing their argument forms. Since m_expand_body
774 speculatively macro expands forms the process must be
777 (m_ident_eqp): Fixed to use proper environment.
779 (renamed_ident): Added DEFER_INTS_EGC.
781 Added prototypes for static functions.
787 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
788 is false, do not produce an error for unbound variables, return a
789 pointer to cell_undef instead.
791 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
795 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
796 destructively changing their argument forms. Since m_expand_body
797 speculatively macro expands forms the process must be reversible.
799 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
800 SCM_IM_LET introduced by named lets.
802 (scm_m_letstar): Use scm_m_body instead of bodycheck.
804 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
805 scm_letrec. scm_letrec1 does not check for a null binding and
806 takes an additional argument to specify the ISYM of the body. Use
807 scm_m_body instead of bodycheck.
809 (scm_m_let): Use scm_m_body instead of bodycheck.
811 (scm_m_expand_body, scm_macroexp): New.
813 (unmemocopy): Account for ISYMs introduced by scm_m_body.
815 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
816 check=1. Throw error for internal defined that have not been
817 rewritten by scm_m_expand_body.
819 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
820 Removed prototype for SCM_APPLY.
822 * tags.h: Added extern declaration of scm_isymnames.
824 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
826 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
828 * lang.c: New file: Beginning of multi-language support.
830 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
832 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
833 (scm_dynamic_wind): Added argument checking for the after guard so
834 that we don't add garbage on the dynwind chain.
835 (scm_swap_bindings): Added.
837 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
838 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
839 (scm_isymnames): New isyms for multi-language support.
841 * eval.c (scm_nil, scm_t): New symbols.
842 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
843 forms for multi-language support.
845 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
847 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
849 Renamed functions in the random function library interface
850 from scm_i_XXX --> scm_c_XXX.
852 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
854 * ports.c (scm_putc): fix line-buffering.
856 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
858 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
859 scm_set_ptob_XXX --> scm_set_port_XXX.
861 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
863 * ports.c, ports.h (scm_make_port_type): New interface for
864 creation of port types (replaces scm_newptob). Just as for the
865 smobs, we need to separate the internal representation of smob
866 types from the interface, so that we easily can add new fields and
867 rearrange things without caring about backward compatibility.
868 This change was forced by the need in GOOPS to create classes
869 representing port types.
870 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
871 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
872 scm_set_ptob_seek, scm_set_ptob_truncate,
873 scm_set_ptob_input_waiting_p): New setters.
874 (scm_newptob): Rewritten to use scm_make_port_type. For backward
876 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
877 (scm_prinport): Removed.
878 (scm_port_print): Added.
879 (scm_print_port_mode): Added.
880 (void_port_ptob, print_void_port, close_void_port, noop0):
881 Removed. Removed #include "genio.h" Added #include "objects.h",
884 * fports.c (prinfport): Moved code from ports.c.
886 (scm_fptob): Removed. Instead use new interface.
887 (scm_make_fptob): Added. (Need to create basic ports in a
888 specific order in ports.c.)
890 * strports.c (scm_stptob, prinstpt, noop0): Removed
891 (scm_make_stptob): Added.
893 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
894 (scm_make_sfport): Added.
896 * filesys.c (scm_dir_print): Don't use the port printing code.
897 Instead provide specific directory printer.
899 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
901 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
904 * smob.c (scm_smob_print): Handle non-existing type name nicely.
905 Removed #include "genio.h"
907 * objects.c (scm_make_port_classes): New function ptr.
909 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
911 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
913 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
914 allow the 1st argument to be a fdes or filename as well as a
915 port (as in the filesys.c version).
917 * filesys.c (scm_truncate_file): removed.
919 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
921 * readline.c, readline.h: Removed.
923 * objects.c, objects.h (scm_port_class): Added.
924 (scm_class_of): Look up port class in scm_port_class.
925 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
926 SCM_INOUT_PCLASS_INDEX): Added.
929 * Makefile.am: Removed genio.c, genio.x.
933 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
935 * init.c: Make sure that scm_post_boot_init_modules is called only
936 once. (Important when using a dumped image.; Thanks to Bernard
939 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
941 * guardians.c (scm_guardian_zombify): Separate scanning for
942 zombies from marking the pairs of the free list.
944 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
945 use the macros. (Thanks to Michael Livshin.)
947 * eval.c (scm_m_lambda): Let bodycheck check the body of the
948 lambda. Let your sins be purified by the blood of the lambda.
949 (Thanks to Eric Hanchrow.)
951 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
952 (Thanks to Valdis Kletnieks.)
954 Fixes for EMX from Mikael Ståldal.
956 * filesys.c: #include <io.h>, if we have it.
957 * scmconfig.h.in: Regenerated.
959 * stime.c (ftime): Delete declaration for this function --- let
960 the system supply it.
962 Cleanups from John Bley.
964 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
966 * gsubr.c: Don't include "gsubr.h" twice.
968 Cleanups for compilation on Irix 6, from David Kaelbling.
970 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
971 regex_t pointer. This is what the callers have, mostly.
972 (scm_regexp_exec): Don't forget to pass the `rx' argument to
973 scm_regexp_error_msg.
975 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
976 int. That way, if we get a warning on this line, it's more likely
977 that we're really missing bits we care about.
979 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
982 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
983 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
984 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
985 cast at all is more appropriate in every case. At the moment, we
986 assume everywhere that SCM is an integral type anyway.
988 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
990 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
991 read_pos after scm_fill_buffer.
993 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
996 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
997 fports.c (fport_fill_buffer): implement the interface change.
999 * ports.c (scm_fill_buffer): interface change: no longer increments
1000 read_pos past the character that's returned. it seems clearer to
1001 leave it to the caller to decide what to do (thanks Jim).
1003 * vports.c (sf_fill_buffer): put the read char into the buffer
1004 as well as returning it.
1006 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure
1009 1999-07-13 Gary Houston <ghouston@easynet.co.uk>
1011 * strports.c (scm_strprint_obj): simplify. start with initial
1013 (st_seek): don't allow string to be extended if seeking past
1014 the end of a read-only port.
1016 1999-07-12 Gary Houston <ghouston@easynet.co.uk>
1018 * strports.c (st_seek): change the resize checks.
1020 * ports.c (scm_ftruncate): throw error if offset works out negative.
1022 * strports.c (st_flush): increase string size in blocks of
1023 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
1024 it's greater and reset read_buf_size.
1025 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
1026 to be maintained for output ports too (it holds the written
1027 part of the string, while write_buf may have unwritten buffer
1029 (st_truncate): rewritten.
1030 (top of file): added a few notes.
1032 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
1034 Patch from Greg Badros:
1035 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
1036 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
1037 (function pointer) argument to scm_make_gsubr and scm_make_subr
1038 calls. This avoids warnings in C++ programs using guile-snarf.
1040 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
1042 * strports.c (st_grow_port): set pt->read_pos. set
1043 pt->read_buf_size one less than pt->write_buf_size if there's
1044 an unwritten char at the end of the string. similarly for
1046 (st_resize_port): renamed from st_grow_port.
1047 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
1048 seek from read_end instead of write_end for SEEK_END.
1049 (st_ftruncate): calculate current length using readbuf, not write
1051 (scm_strport_to_string): use read_buf_size for length.
1052 (stfill_buffer): don't re-initialise the readbuf.
1054 1999-07-05 Gary Houston <ghouston@easynet.co.uk>
1056 * strports.c (scm_strport_to_string): new procedure.
1057 (scm_call_with_output_string, scm_strprint_obj): use
1058 scm_strport_to_string.
1059 used SCM_INUM0 instead of SCM_MAKINUM (0) in a few places.
1061 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1063 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)
1065 Fri Jun 25 22:14:32 1999 Greg Badros <gjb@cs.washington.edu>
1067 * smob.c: added scm_make_smob_type_mfpe (), scm_set_smob_mfpe ();
1068 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
1069 and "bigneg" smob types.

1164 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1166 * struct.c, struct.h:
1168 In order to support different kinds of deallocation, a destructor
1169 slot has been added to struct vtables. This allows for structs
1170 containing pointers to other memory blocks.

1243 Patch from Greg Harvey:
1244 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1245 around the condition of an `if', `while', etc., even if the
1246 condition is a macro invocation that expands to something
1247 surrounded by parens. It's more readable.
1249 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1250 proper lists, and of the appropriate lengths.
1251 (check_map_args): New function. (Thanks to Greg Harvey for the
1254 1999-06-19 Michael Livshin <mike@olan.com>

1291 (scm_weak_size, scm_n_weak): Deleted.
1292 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
1293 vectors without allocating new storage during GC, using
1294 scm_weak_vectors as the head of the chain.
1295 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1296 instead of stepping through an array.
1297 (scm_gc_sweep): Update offset used to find start of weak vector to

1303 (scm_igc): Set and clear already_in_gc; abort if it's set at
1306 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
1308 Fix from Gary Houston:
1309 * fports.c (local_seek): Signal an error if the seek fails.
1310 * ports.c (scm_lseek): Don't check return value of port's seek
1311 function; it's its job to signal an error if there's a problem.
1313 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
1315 * strports.c (scm_call_with_output_string): Don't include the

1322 actually correspond to the changes described below. I got the
1323 ChangeLog entries and the patch from two different places...
1325 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1327 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1328 it shows up as terrible performance, as we GC constantly.
1330 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1331 newline. A bit faster, and definitely hairier.
1332 (scm_read_line): Count newlines here instead.
1334 * strings.c (scm_take_str): New function.
1335 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1336 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use

1339 Add some simple-minded support for line buffered ports.
1340 * ports.h (SCM_BUFLINE): New flag for ports.
1341 * init.c (scm_init_standard_ports): Request line-buffering on
1342 the standard output port.
1343 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1345 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1346 and there's a newline to be written, flush the port.
1348 Gary Houston's open-buffer port patches:
1350 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1352 * ports.c: (scm_lseek): clear buffers even if just reading current

1363 strports.c (scm_mkstrport): check that pos is reasonable.
1364 ioext.c (scm_ftell, scm_fseek): use lseek.
1365 (SCM_CLEAR_BUFFERS): macro deleted.

1370 ports.c (scm_ftruncate): new procedure.
1371 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
1372 strports.c (st_seek, st_grow_port): new procs.
1373 fports.h (scm_port): change size types from int to off_t.
1374 ports.c (scm_init_ports): initialise the seek symbols here
1375 instead of in ioext.c.
1376 strports.c (scm_call_with_output_string): start with an empty
1377 string, so seek and ftruncate can be used.
1379 gdbint.c: adjust string port usage.
1381 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1383 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1384 equivalent to fflush for the read buffer.
1385 * ports.c (scm_newptob): set read_flush.
1386 ports.c (void_port_ptob): set read_flush.
1387 fports.c (local_read_flush): new proc. add to ptob.
1388 strport.c (st_read_flush): likewise.
1389 vport.c (sf_read_flush): likewise.
1390 fports.h (struct scm_fport): remove random member. there's nothing
1391 left but fdes. leaving it as a struct to allow for future changes.
1392 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1393 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1394 ptob proc if the read buffer is filled.
1396 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1398 * ports.h (scm_port): add a rw_random member and replace
1399 reading and writing members with rw_active member.
1400 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1402 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1404 * ports.h (struct scm_port_table): add writing and reading members
1405 to replace write_needs_seek: it isn't good enough for non-fports.
1406 ports.c, ioext.c, fports.c: corresponding changes.
1407 (struct scm_port_table): give it a typedef and rename to scm_port.
1408 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1409 corresponding changes.

1419 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1420 signals (it was only being done for handlers installed from Scheme).
1421 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1422 waiting for input caused an EINTR error from read.
1424 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1426 * ports.h (struct scm_port_table): make all the char members
1427 unsigned, so they convert to int without becoming negative if large.
1429 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1431 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1432 with threads enabled. rename this procedure to
1433 fport_wait_for_input and take a port instead of a fdes.
1434 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1436 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1437 get readline support working again: use fdopen to get FILE objects.
1439 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1441 * gc.c (scm_init_storage): install an atexit proc to flush the
1443 (cleanup): the new proc. it sets a global variable which can be
1444 checked by the ptob flush procs to avoid trying to throw
1445 exceptions during exit. not very pleasant but it seems more reliable.
1446 * fports.c (local_fflush): check terminating variable and if set
1447 don't throw exception.
1448 * CHECKME: that the atexit proc is installed if unexec used.
1450 * throw.c (scm_handle_by_message): don't flush all ports here.
1451 it still causes bus errors.
1453 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1454 and move to ioext.c.
1456 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1458 * ports.c (scm_char_ready_p): check the port buffer and call the
1459 ptob entry if needed.
1461 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1462 ptob initialisers. use it in char-ready
1464 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1466 * vports.c (sfflush): modified to write a char (since softports
1467 currently use shortbuf.)
1469 * fports.c (scm_standard_stream_to_port): moved to init.c and
1472 * init.c (scm_init_standard_ports): make stdout and stderr
1473 unbuffered if connected to a terminal. with stdio they
1474 were line-buffered by default.
1476 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1479 * ports.h (scm_ptobfuns): change fflush return to void.
1480 change flush proc definitions.
1482 * strports.c (scm_call_with_output_string): get size from
1483 buffer instead of port stream.
1484 (st_flush): new proc.
1486 * ports.h (struct scm_port_table): added write_end member,
1487 as an optimisation. set it where write_buf_size is set.
1489 * ports.h (struct scm_port_table): change stream from void *
1490 back to SCM. SCM presumably must be large enough to hold a
1491 pointer (and probably vice versa but who knows.)
1492 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1494 (scm_puts): rewritten
1495 * fports.c (local_ffwrite, local_fputs): removed.
1496 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)
1497 * vports.c (sfputc, sfputs, sfwrite) likewise.
1498 * ports.c (write_void_port, puts_void_port): removed.
1499 (putc_void_port, getc_void_port, fgets_void_port): likewise.
1501 * ports.c (scm_lfwrite): rewritten using fport.c version.
1503 * fports.c (local_fputc): deleted.
1505 * ports.c (scm_add_to_port_table): initialise write_needs_seek.
1507 * ports.h (scm_ptobfuns): add seek function pointer.
1508 * fports.c: set it to local_seek, new procedure.
1511 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1512 use ptob for seek. take ptob instead of fport arg.
1514 * ports.h (struct scm_port_table): new member write_needs_seek,
1515 replaces reading member in fport struct.
1517 * vports.c (sfgetc): store the getted char into the buffer.
1518 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1519 the Scheme interface is still a procedure that gets a char.
1520 (scm_make_soft_port): set up the port buffer (shortbuf).
1522 * fports.c (local_fgetc, local_fgets): deleted.
1523 * strports.c (stgetc): likewise.
1524 * ports.c: scm_generic_fgets: likewise.
1526 * ports.h (scm_ptobfuns): add fill_buffer.
1527 * ports.c (scm_newptob): assign it.
1528 * strports.c (scm_mkstrport): set up the buffer.
1529 put just the string into the stream, not cons (pos stream).
1530 (stfill_buffer): new proc.
1532 * ports.h: fport buffer moved into port table: to be
1533 used for all port types.
1535 1998-12-20 Gary Houston <ghouston@easynet.co.uk>

1541 scm_bind, scm_listen, scm_accept, scm_getsockname,
1542 scm_getpeername, scm_recv, scm_send, scm_recvfrom,
1544 use SCM_FPORT_FDES. use SCM_OPFPORTP not SCM_FPORTP.
1546 * posix.c (scm_getgroups): use SCM_ALLOW/DEFER_INTS.
1547 (scm_ttyname): use SCM_FPORT_FDES.
1548 (scm_tcgetpgrp, scm_tcsetpgrp): likewise.
1550 * filesys.c (scm_chown): use SCM_FPORT_FDES.
1551 (scm_chmod, scm_stat, scm_truncate_file: likewise.

1554 (scm_fdes_to_ports): modified.
1555 (scm_fdopen): use scm_fdes_to_port.
1557 * ports.c (scm_init_ports): don't try to flush ports using
1558 atexit(). it's too late, errors will cause SEGV.
1560 * fports.c (scm_fport_buffer_add): new procedure.
1562 * fports.h (SCM_FDES_RANDOM_P): new macro. use it in
1563 scm_fdes_to_port and scm_redirect_port.
1565 * ioext.c (scm_redirect_port): use setvbuf to set buffers in the
1566 new port. reset fp->random.
1568 * fports.c (scm_fdes_to_port), ports.c (scm_void_port),
1569 filesys.c (scm_opendir):
1570 restore defer interrupts while the port is constructed.
1571 (scm_setvbuf): if mode is _IOFBF and size is not supplied,
1572 derive buffer size from fdes or use a default.

1728 * strop.c (scm_string_capitalize_x): Use the SCM object `s' in

1732 * strop.c (scm_substring_move_x): New function, which can handle
1733 arbitrary overlapping substrings.

1808 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1810 * numbers.c (isfinite): Define this macro if not defined: Return a
1811 non-zero value if X is finite. (From ISO C 9x standard.)

1864 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1866 Most of this batch of changes is about how to deal with extended
1867 types when an object system is loaded into Guile. A nice object
1868 system is capable of representing Guile's types as class objects.
1870 For example, we want a regular expression to be of class <regex>.
1871 But regular expressions are smobs which aren't under direct
1872 control of the object system, so there has to be some mechanism
1873 which informs the object system that a new class should be created
1874 which can represent the smob type. I call this a "wrapper class".
1876 * objects.c: #include "smob.h";
1877 (scm_class_keyword): Removed. (Class is automatically created by
1879 (scm_smob_class): Array of smob classes indexed by smobnum.
1880 (scm_make_extended_class): "Plugin" function pointer for creation
1881 of wrapper classes for smob and struct types.
1882 (scm_class_of): Handle compiled closures. (Currently regarded as
1884 Use scm_smob_class to handle smob types;
1885 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1886 through scm_smob_class;
1889 * smob.c (scm_newsmob): Also create a wrapper class if
1890 scm_smob_class has been initialized.
1892 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1893 type code and smobnum.
1895 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1896 (scm_struct_table): Weak key table with auxilliary information for
1897 struct types. Currently used for names and wrapper classes.
1898 (scm_struct_ihashq): Hash function for structs.
1899 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1900 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1901 for accessing names of vtables. The record implementation in
1902 boot-9.scm currently uses the setter to record the name of record
1903 types. When the object system is initialized, it can use this
1904 information to create wrapper classes with suitable names.
1905 (scm_init_struct): Allocate scm_struct_table.
1906 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1907 (struct tags are a finite resource and we might want to restrict
1908 the use of tags to vtables only. E.g., Goops only uses tags for
1910 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1912 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1915 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1916 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1917 Used for access of struct table entries.
1919 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1920 (scm_hash_fold): New procedure. Used to process all entries in a
1921 hash table (in no particular order).
1923 Argh! For the umpteenth time I got compilation errors because of
1924 the "intuitive" name `kw'. This has to have an end:
1926 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1927 "kw" --> "keywords" everywhere.
1928 (I doubt that this will cause big compatibility problems since the
1929 application interface is unaffected.)
1931 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1933 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1935 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1936 column inums to native form.
1938 Improvement of backtraces: Introduces a new stack narrowing
1939 specifier, #t, for the inner cut. (See further in the comments in

1943 (Used to flag certain system procedures which shouldn't turn up in
1946 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1947 modules which aren't "user" modules and the code of which

1951 Extract the lookup closure from an environment.
1952 (scm_system_module_env_p): New function: Return non-#f if MODULE
1955 * stacks.c: #include "eval.h"; #include "procprop.h";

1958 * debug.c (scm_procedure_name): Use name property in the default
1961 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1963 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1965 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1966 procedure throughout.
1968 * print.c (scm_iprin1): Removed extraneous space when printing
1969 procedure-with-setters.
1971 Entity and operator setter slots were introduced as a complement
1972 to the <procedure-with-setter> type in order to support entities
1973 and operators with setters in a reasonable and efficient way.
1974 * procs.c (scm_procedure, scm_setter): Handle entity and operator

1990 directly through the instance.
1992 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1994 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1995 scm_struct_i_flags instead of scm_vtable_index_layout!
1997 * list.c (scm_list_star): New procedure.
1999 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

2074 numbers.h, options.h, procs.h, ramap.h, read.h, smob.h,
2075 strports.h, symbols.h, unif.h: Update variable declarations and
2076 function prototypes for above changes.

2079 sysdep_dynl_unlink, sysdep_dynl_func): Arguments FNAME, SUBR, and
2080 SYMB now point to const.
2082 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2084 * print.c (scm_iprin1): Use scm_procedure_name instead of
2085 scm_procedure_property for compiled closures.
2087 * tags.h (scm_tc7_pws): New procedure type. Four representations
2088 for procedure-with-setters were considered before selecting this
2091 1. A closure where the CODE and ENV slots are used to represent
2092 the getter and a new SETTER slot is used for the setter. The
2093 original getter is stored as a `getter' procedure property. For
2094 closure getters, the CODE and ENV slots contains a copy of the
2095 getter's CODE and ENV slots. For subr getters, the CODE contains
2098 2. A compiled closure with a call to the getter in the cclo
2099 procedure. The getter and setter are stored in slots 1 and 2.
2101 3. An entity (i.e. a struct with an associated procedure) with a
2102 call to the getter in the entity procedure and the setter stored
2103 in slot 0. The original getter is stored in slot 1.
2105 4. A new primitive procedure type supported in the evaluator. The
2106 getter and setter are stored in a GETTER and SETTER slot. A call
2107 to this procedure type results in a retrieval of the getter and a
2108 jump back to the correct eval dispatcher.
2110 Representation 4 was selected because of efficiency and
2113 Rep 1 has the advantage that there is zero penalty for closure
2114 getters, but primitive getters will get considerable overhead
2115 because the procedure-with-getter will be a closure which calls
2118 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
2119 <procedure-with-setter>, but together with rep 2 it suffers from a
2120 three level dispatch for non-GOOPS getters:
2122 cclo/struct --> dispatch proc --> getter
2124 This is because the dispatch procedure must take an extra initial
2125 argument (cclo for rep 2, struct for rep 3).
2127 Rep 4 has the single disadvantage that it uses up one tc7 type
2128 code, but the plan for uniform vectors will very likely free tc7
2129 codes, so this is probably no big problem. Also note that the
2130 GETTER and SETTER slots can live directly on the heap, using the
2131 new four-word cells.
2133 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,
2134 SCM_SETTER): New macros.

2160 * eval.h: Declare scm_s_set_x, scm_sym_set_x;
2162 * eval.c: Renamed "set" --> "set_x" in various names for
2163 consistency of name correspondence between Scheme and C;
2164 Renamed scm_i_set_x --> scm_sym_set_x and made global.
2165 Renamed s_set_x --> scm_s_set_x and made global.
2167 1999-01-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2169 * random.c (scm_i_random_bignum): Made independent of endianness.

2187 scm_rstate from seed.
2188 (scm_copy_random_state, scm_seed_to_random_state): New functions.
2189 (scm_make_random_state): Removed.
2191 * random.c (scm_make_random_state): Use scm_i_make_rstate().

2195 * random.c: Bugfix: Retrieve and store most significant 32 bits in
2196 different order if the machine is bigendian.

2202 from first arg before equal elements in second arg in result.
2203 (scm_merge_list_step): Bugfix: Don't presume that arguments in a C
2204 function call are executed in a well defined order.
2206 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2208 * alloca.c (alloca): Cast value returned by malloc. (Thanks to
2211 1999-01-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2213 * random.c: Removed alloca includes.
2215 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2217 * Makefile.in: This changed, for some reason I don't really
2218 understand, when I ran automake in the top level directory. This
2219 may be contamination by Cygnus internal releases. If you re-run
2220 automake and this change gets reverted, don't worry about it.
2222 1999-01-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2224 * sort.c, sort.h: New files: Implement slib's and scsh's sort
2225 interfaces. Author: Roland Orre.

2235 Renamed s_bignum --> scm_s_bignum.
2237 * random.c, random.h: New files: Random number support.
2238 Interface same as slib's.
2240 * Makefile.am: Added random.c, random.h, random.x.
2242 * init.c: #include "random.h";
2243 (scm_boot_guile_1): Call scm_init_random ().
2245 1998-12-23 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2247 * Makefile.am: New files: guardians.c, guardians.x, guardians.h
2249 * guardians.c, guardians.h (scm_make_guardian,
2250 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
2251 scm_get_one_zombie, scm_init_guardian): This is an implementation
2252 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
2253 David Eby (1993) "Guardians in a Generation-Based Garbage
2254 Collector" ACM SIGPLAN Conference on Programming Language Design
2255 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
2256 /pub/scheme-repository/doc/pubs/guardians.ps.gz
2257 Author: Michael N. Livshin.
2259 * gc.h (SCM_MARKEDP, SCM_NMARKEDP): New macros.
2261 * gc.c (scm_igc): Call scm_guardian_gc_init and
2262 scm_guardian_zombify.

2266 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2268 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
2271 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2273 Move the procedure slots of entities to invisible slots (so that
2274 we can have operator class objects which themselves are entities).
2275 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
2276 SCM_STRUCTF_ENTITY): New constants.
2278 * struct.c (scm_make_struct): Allocate "invisible" room for
2279 procedures if SCM_STRUCTF_ENTITY is set in vtable.
2281 * gc.c (scm_gc_mark): Mark entity procedures.
2283 * struct.c, struct.h (scm_alloc_struct): Renamed from alloc_struct

2288 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
2289 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
2291 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
2293 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
2294 of syntactic forms, similar to SCM_PROC.
2295 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
2296 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
2297 for the name symbols when needed.
2299 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
2301 * Makefile.in: Regenerated.
2303 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
2305 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
2306 take the address of _into; it might be a register. Just have
2307 scm_debug_newcell return the new cell.
2308 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2309 taking the address of a place to store it as an argument.
2310 * gc.h (scm_debug_newcell): Change declaration.
2311 (Thanks to Greg Harvey.)
2313 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2315 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
2316 Replaces old names serial-array-copy! and serial-array-map!.
2318 * evalext.c (map-in-order): New name. Replaces serial-map.

2322 * smob.c (freeprint): New function.
2323 (freecell): Use it to print freed objects, for slightly easier
2326 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2328 * backtrace.c (display_frame): Made more robust. Doesn't throw an
2329 error if no source properties can be found for a frame. (Thanks
2330 to Christian Lynbech.)
2332 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2334 * objects.h: Removed slots direct_supers and direct_slots from the
2335 definitions of the rudimentary classes described by objects.h.
2337 * objects.c, objects.h (scm_entity_p): New procedure. Together
2338 with the predicates scm_procedure_p and scm_struct_p, this
2339 predicate makes it possible to differ between structs, entities
2342 * modules.c, modules.h (scm_resolve_module): New function.
2344 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2346 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2347 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2350 * objects.c (scm_entity_p): New procedure.
2352 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
2353 for asubrs, rpsubrs, lsubrs and lsubr_2s.
2355 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2357 * procprop.h (scm_i_procedure_arity): Added declaration.
2359 * procprop.c (scm_i_procedure_arity): Made global; New code to
2360 handle operators and entities.
2361 (scm_procedure_property): No need to call scm_procedure_p since
2362 scm_i_procedure_arity now does all necessary type checking.
2363 Added #include "objects.h".
2365 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2366 s_add_hook_x --> s_remove_hook_x.
2367 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
2368 Added #include "procprop.h"
2370 * feature.c, feature.h (scm_reset_hook_x): New procedure.
2371 (scm_make_hook): Optional argument defines number of arguments to
2373 (scm_make_named_hook): Take number of args as second arg.
2374 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2375 boot-9.scm for a while); First arg is the hook. The rest are
2376 arguments passed on to the hook procedures.
2378 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2380 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2381 scm_logbit_p): Do the computation in ulongs. This is not as nice
2382 as doing it in bignums, but at least it's good enough for
2383 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2385 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2386 subexpressions. (Thanks to Charbel Jacquin.)
2388 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2390 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2391 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2392 (scm_make_named_hook): New function.
2394 * feature.c: Added #include "eval.h".
2396 * modules.c (scm_make_module): Beautify the module.
2398 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2400 * modules.c, modules.h: New files: C interface to modules. (This
2401 is necessary in order to interface the object system to Guile
2402 properly. The guts of these modules will be replaced by the new
2403 module system in the future.)
2405 * init.c: Added #include "modules.h"
2406 (scm_boot_guile_1): Call scm_init_modules.
2407 (invoke_main_func): Call scm_post_boot_init_modules.
2409 * Makefile.am: Added modules.c, modules.x, modules.h.
2411 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2413 * procs.c: #include "objects.h"
2414 (scm_procedure_p): Return #t also on structs which are operators.
2416 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2417 <operator-metaclass> and <entity-class> to <standard-class>,
2418 <operator-class> and <entity> in order to conform with STKlos
2421 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2422 which isn't an operator.
2423 (SCM_APPLY): Ditto, but jump to badproc.
2425 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2427 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2428 Previously, structs implanted in code were interpreted as forms
2429 the operator of which was a gloc. We solve this by checking for
2430 the zero in the emulated vcell in the struct vtable. Since
2431 implanted structs always will look like forms with a gloc
2432 operator, execution will only be slowed down by maximally one
2433 extra test-and-branch per application.
2435 * evalext.c (scm_definedp): Removed check for isyms; Added a
2436 second optional argument: It is now possible to supply an
2437 evaluation environment in which to look for the symbol.
2439 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2441 * readline.c (scm_init_readline): Set
2442 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2444 * coop.c (coop_condition_variable_wait): Removed
2445 (coop_condition_variable_wait_mutex): Folded logic of
2446 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2447 prevent condvar signal lossage. Previously, another thread could
2448 start to run after unlocking the mutex but before putting the
2449 current thread on the wait queue. If that thread then would
2450 signal the first, the signal would be lost. (Thanks to Christian
2453 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2455 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2458 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2460 * objects.c (scm_i_make_class_object): Renamed from
2461 make_class_object; exported; error checking moved to
2462 scm_make_class_object and scm_make_subclass_object.
2463 (scm_make_class_object, scm_make_subclass_object): Use
2464 scm_i_make_class_object.
2465 (scm_make_subclass_object): Let the subclass have same metaclass
2468 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2470 * debug.c (scm_debug_options): Bugfix: Set the value of
2471 scm_stack_checking_enabled_p after setting debug options;
2472 #include "stackchk.h". (Thanks to Richard Polton.)
2474 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2476 * unif.c (scm_array_contents): removed unnecessary test for 0
2479 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2481 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2482 Replaced by macro `collect' in boot-9.scm.
2484 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2486 * eval.c (scm_copy_tree): Copy source properties if existent.
2488 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2489 don't, we may end up passing memoized source to a transformer.)
2491 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2493 * stack.c (get_applybody): Help function which lookups the first
2494 body form of the apply closure.
2495 (read_frames): Prevent the source of the first form of the apply
2496 closure from being recorded. This would only be confusing.
2498 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2499 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2501 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2503 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2505 (read_frames): Use SCM_MACROEXPP.
2507 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2509 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2510 don't contain interesting information since all arguments are
2511 present in the frame which applies the compiled closure anyway.);
2512 Skip the transformer application frames.
2514 * print.c (scm_iprin1): Print gsubrs as primitives.
2516 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2518 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2520 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2521 that we can identify these in a backtrace. (This change doesn't
2522 introduce any significant speed penalty.)
2524 * eval.c: Added note about `serial-map' using scm_map.
2526 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2527 readline options. They should reside in their own options array.
2529 * readline.c, readline.h (scm_readline_options,
2530 scm_readline_opts): Moved readline options here.
2532 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2534 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2535 SCM_ROCHARS instead of SCM_CHARS.
2537 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2538 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2540 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2542 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2543 This is quite important since the latter clears the
2544 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2545 every single character read...
2547 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2549 * print.c (scm_iprin1): Removed suspect looking (and indeed
2550 malevolent) semicolon after test for user supplied closure print
2551 procedure. (Thanks to Telford Tendys.)
2553 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2554 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2555 starting to search the list. Removed call to sloppy_mem_check.
2557 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2558 procedures: Same as scm_delq_x et al, but delete maximally one
2561 * options.c (scm_options, scm_init_options): GC-protect option
2562 values of type SCM. (Thanks to Telford Tendys.)
2564 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2566 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2567 make sure that there always is a "real" scm_lookupcar.
2569 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2571 * read.c, read.h (scm_read_opts): New read options
2572 "history-length" and "history-file".
2573 (scm_read_options): Stifle history to history length.
2575 * readline.c (scm_read_history, scm_write_history): New procedures.
2577 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2579 * eval.h (scm_macro_eval_x): Removed declaration.
2581 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2582 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2583 Renamed and made global.
2585 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2586 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2588 * evalext.c, evalext.h: New files. Contain non-R5RS things
2589 having to do with evaluation.
2591 * evalext.c (scm_serial_map): New procedure: Version of `map'
2592 which guarantees that the procedure is applied to the lists in
2594 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2595 returns a list of the results of the body forms instead of the
2596 result of the last body form.
2597 (scm_definedp, scm_m_undefine): Moved from eval.c
2599 * evalext.h (scm_m_sequence_to_list): Added declaration.
2601 * macros.c, macros.h: New files.
2602 (scm_procedure_to_syntax, scm_procedure_to_macro,
2603 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2604 scm_macro_name, scm_macro_transformer): Moved from eval.c
2605 (scm_make_synt): Moved from eval.c
2607 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2609 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2612 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2614 * debug.c, print.c: Added #include "macros.h".
2616 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2618 This change adds the ability to use `unread-char' multiple times
2619 without interspersed reads and adds the new procedure
2620 `unread-string'. The change is optimized for the common case of
2621 unreading a single character. This is also the reason behind the
2622 choice to store characters in the port itself: in most cases no
2623 extra malloc is required.
2625 The amount of code in some macros in ports.h has been increased to
2626 the extent that they would fit better as C functions, but, since
2627 this code belongs to the port representation, such functions
2628 should be placed in ports.c which would cause calls back and forth
2629 between ports.c and genio.c. That is not good for performance.
2630 Also, keeping them as macros allows the compiler to do some
2631 optimizations which are needed to make the current interface
2632 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2634 One benchmark (Guile startup time) indicates an increase of
2635 loading speed of 1%. Another (reading (using `read') boot-9.scm
2636 10 times) shows no change in performance.
2638 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2639 made to find a beautiful solution.)
2641 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2642 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2643 character. (SCM_CLRDY clears all.)
2644 (SCM_N_READY_CHARS): New macro: Returns number of unread
2645 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2646 (struct scm_port_table): New fields: `entry' contains port table
2647 index, `cp' points to last unread char, `cbuf' is the buffer for
2648 unread chars, `cbufend' points after end of the character buffer.
2650 * ports.h, ports.c (scm_unread_string): New procedure.
2651 (scm_grow_port_cbuf): New function.
2653 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2655 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2656 to read unread characters. Use SCM_TRY_CLRDY instead of
2659 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2661 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2663 * genio.c, genio.h (scm_ungets): New function.
2665 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2668 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2670 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2671 declarations. (Thanks to Russ McManus.)
2673 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2675 * numbers.c (num2long): As a software archeologist, I'm proud of
2676 this finding! :) Preliminary dating suggests an almost 4 year old
2677 remnant from the SCM ancestor. The sample has been removed from
2678 the finding site and is now safely stored in the repository.
2680 * numbers.h: Removed prototype for num2long.
2682 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2684 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2685 array as second arg.
2686 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2687 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2688 * gh.h: Updated and added prototypes.
2690 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2692 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2694 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2696 * guile-snarf.in: Never generate an empty file. (Thanks to
2699 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2700 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2701 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2702 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2703 gh_new_procedure5_0): Specify argument types, to appease C++
2704 compilers. (Thanks to Brad Bowman.)
2706 Bug reports from Russ McManus:
2707 * guile-snarf.in: If the CPP environment variable is set, use that
2708 as the C preprocessor, instead of the preprocessor autoconf
2710 * snarf.h (SCM_PROC): Cast the function pointer passed to
2711 scm_make_gsubr, to satisfy C++.
2713 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2714 Use the handler passed, instead of ignoring it and using
2715 gh_standard_handler. (Thanks to Etienne Bernard.)
2717 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2719 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2722 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

2739 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2742 * script.c (scm_compile_shell_switches): Define
2743 use-emacs-interface in the root module, so the repl code can see
2744 it. See today's change to top-repl in ice-9/boot-9.scm.
2746 * filesys.c (set_element, get_element): Make sure that `element'
2747 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2748 Boekemeier and Jorgen "forcer" Schaefer.)
2750 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2752 * chars.c (scm_charnames): In ASCII character name table, make
2753 newlines print as #\newline by default, not #\nl.
2755 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2756 alphabetical order. Oh thrills. But it helps me know how far
2757 along in the compilation I am.
2758 * Makefile.in: Regenerated.
2760 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2762 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2763 #bytes(...) to #y(...), and syntax for short vectors from
2764 #short(...) to #h(...). This may seem nutty, but, like the other
2765 uniform vectors, byte vectors and short vectors want to have the
2766 same print and read syntax (and, more basic, want to have read
2767 syntax!). Changing the read syntax to use multiple characters
2768 after the hash sign breaks with the conventions used in R5RS and
2769 the conventions used for the other uniform vectors. It also
2770 introduces complexity in the current reader, both on the C and
2771 Scheme levels. (The Right solution is probably to change the
2772 syntax and prototypes for uniform vectors entirely.)
2774 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2776 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2777 (Thanks to Jorgen "forcer" Schaefer.)
2778 * ports.h (SCM_NOFTELL): New flag.
2779 * fports.c (local_fgets): If it's set, use the generic fgets.
2780 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2782 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2784 * script.c (scm_compile_shell_switches): Add handling of -q switch
2785 (inhibit loading of user init file).
2786 (scm_shell_usage): Add usage text for -q switch.
2787 (scm_compile_shell_switches): Always load user init file first if
2788 it is loaded at all.
2790 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2792 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2793 and is now broken under NetBSD. I can't fathom what it's trying
2794 to do, so I've replaced it with something that I do understand,
2795 which seems to work, and which isn't broken on NetBSD. "Progress?
2796 You Decide." (Thanks to Perry Metzger.)
2798 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2799 signed/unsigned comparison.
2801 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2803 Warning fixes from Greg Harvey:
2804 * unif.c (scm_array_set_x): initializer for pos
2805 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2806 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2807 initializers for field_type, since EGCS so desparately wants to
2809 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2810 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2811 when GUILE_DEBUG is defined.
2812 * dynwind.h (scm_wind_chain): Same.
2813 * ports.h (scm_pt_size, scm_pt_member): Same.
2814 * print.h (scm_current_pstate): Same.
2815 * procs.h (scm_make_cclo): Same.
2817 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2819 Handle short and long long uniform arrays properly. (Thanks to
2821 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2822 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2823 scm_tc7_llvect (long long vectors).
2825 Change the way libguile and boot-9.scm are timestamped, to try to
2826 get rid of these spurious mismatch warnings. Now both
2827 libguile/versiondat.h and ice-9/version.scm are generated directly
2828 by the configuration process, rather than having version.scm
2829 generated directly, and libguile/versiondat.h generated by the
2830 Makefile, which is generated by configure. It seems that
2831 sometimes the Makefile would change, but versiondat.h depends on
2832 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2833 * Makefile.am (versiondat.h): Target removed; this is generated
2834 directly by the configure script now.
2835 (BUILT_SOURCES): Remove versiondat.h.
2836 * versiondat.h.in: New file, transformed by the configure script
2838 * Makefile.in: Regenerated.
2840 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2841 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2842 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2843 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2844 if we want to use them in a header file some day, we can. (Thanks
2845 to Michael Livshin.)
2847 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2848 SCM numbers, so we won't have rollover problems; the range of a
2849 signed long in milliseconds is about 25 days. (Thanks to Karl
2852 Don't redefine sleep and usleep; fix this problem now.
2853 * coop.c (sleep, usleep): Remove declarations; we don't use or
2854 redefine these any more.
2855 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2856 job of usleep and sleep in a thread-friendly way. We can use
2857 these in the rest of Guile. Define versions for systems both with
2858 and without iselect.
2859 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2860 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2861 we're just using it, not redefining it, we can use a K&R style
2863 (sleep): Declare this, too, if the system hasn't.
2864 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2865 scm_uthread_sleep if they're available; otherwise, just call the
2867 * scmconfig.h.in: Regenerated.
2869 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2871 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2873 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2875 * threads.c: Doc fix.
2877 The argument type of usleep varies from system to system,
2878 as does the return type. We really shouldn't be redefining usleep
2879 at all, but I don't have time to clean that up before the 1.3.
2880 release. It's on the schedule for afterwards. (Thanks to Julian
2882 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2884 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2885 * scmconfig.h: Regenerated.
2887 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2888 right way to handle system variation. Autoconf's approach is the
2890 * simpos.h (scm_software_type): Declaration deleted.
2892 * script.c (scm_find_executable): Don't test if unix is #defined
2893 here; first, NetBSD doesn't #define it, and second, it's the wrong
2894 way to go about these things. (Thanks to Perry Metzger.)
2895 (dld_find_executable): Delete this MSDOS support code. This isn't
2896 the way we want to support this; it needs to be rethunk at a
2899 * genio.c (scm_do_read_line): Don't just politely check that the
2900 line was either non-empty or EOF. Abort if it's empty and not
2903 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2905 * scmconfig.h.in: Regenerated.
2907 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2910 * genio.c (scm_do_read_line): Count lines correctly when the file
2911 doesn't end in a newline.
2913 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2915 * genio.c (scm_do_read_line): Maintain the line count correctly.
2916 (Thanks to Harvey J. Stein and Greg Harvey.)
2918 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2921 * numbers.c (big2str): Protect t from garbage collection until
2922 we're done. (Thanks to Gary Houston.)
2924 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2926 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2928 * Makefile.in: Regenerated.
2930 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2931 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2934 Do magic to mix reads and writes on stdio FILE-based ports.
2935 (Thanks to Christian Lynbech.)
2936 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2938 (pre_read, pre_write): New functions.
2939 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2940 local_fputs): Call them.
2941 (local_fflush): Mark the port as ready for reading and writing.
2942 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2943 flags on new port objects. This might not be accurate --- who
2944 knows what state the FILE * is in when we get it --- but it won't
2945 do extraneous calls to fflush or fseek, so it's no worse than the
2946 behavior before this change.
2947 * ports.h: Add comment.
2949 Centralize the creation of port objects based on stdio FILE * in
2950 fports.c; don't just throw them together anywhere.
2951 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2952 what the rest of Guile wants. Don't set the revealed count;
2953 that's only appropriate for stdin, stdout, stderr.
2954 (scm_standard_stream_to_port): This function does set the revealed
2956 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2957 not scm_stdio_to_port.
2958 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2959 * fports.c (scm_open_file): Same.
2960 * posix.c (scm_pipe): Same.
2961 * socket.c (scm_sock_fd_to_port): Same.
2962 * ioext.c (scm_fdopen): Same.
2963 (scm_freopen): Moved from here to...
2964 * fports.c (scm_freopen): ... here. This is really something that
2965 munges the internals of an fport, so it should go here.
2966 * fports.h (scm_stdio_to_port): Adjust prototype.
2967 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2968 * ioext.h (scm_freopen): Prototype removed.
2970 * filesys.c (set_element, get_element): This can work on both pipe
2971 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2974 * scmconfig.h.in: Regenerated.
2976 Change the definition of the functions in scm_ptobfuns so that
2977 they get passed the port object, not the port's stream.
2978 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2979 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2980 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2981 Pass the port itself to the scm_ptobs function.
2982 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2983 scm_generic_fgets): Same.
2984 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2985 getc_void_port, fgets_void_port, close_void_port): Just change the
2986 argument names; these functions don't really do anything.
2987 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2988 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2989 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2990 Also, use prototyped definitions, and get rid of the extra
2992 (scm_fptob, scm_pipob): We don't need casts here any more.
2993 * strports.c (prinstpt): Use prototype declarations.
2994 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2995 and use SCM_STREAM to get the string info. Also, use prototyped
2996 definitions, and get rid of the extra declarations.
2997 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
3000 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
3001 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
3003 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
3004 scm_fgets, for consistency.
3005 (scm_fptop, scm_pipob): References updated.
3007 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
3009 Include the source location in error messages for scripts.
3010 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
3011 stack is still there when we catch the error.
3012 * throw.c (handler_message): If we are handling an error with a
3013 message, then put together the proper arguments and call
3014 scm_display_error, instead of scm_display_error_message. That
3015 displays source location, if it can find it.
3017 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
3019 * gc.c (scm_unprotect_object): Change this so that calls to
3020 scm_protect_object and scm_unprotect_object nest properly.
3021 (scm_protect_object): Doc fixes.
3023 * strings.c (scm_string_set_x): Require the argument to be a
3024 writable string, not a substring or a symbol.
3025 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
3026 (Thanks to John Redford and Charbel Jacquin.)
3028 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
3030 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
3032 * eval.c (safe_setjmp): Remove this misunderstanding.
3033 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
3036 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
3038 * libguile.h: Mark these as C declarations, for compilation by C++
3041 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
3042 __cplusplus clause. I seriously doubt this ever worked the way
3043 the author seems to have intended.
3045 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
3047 Utterly needless cleanups to hopelessly messy code.
3048 * ports.c: Doc fixes.
3049 (scm_fflush): Moved to ...
3050 * genio.c (scm_fflush): ... here, amongst all the other port
3051 method invocation functions.
3052 * genio.h, ports.h: The prototype moves too.
3054 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
3056 * backtrace.c (display_error_body): The current frame does not
3057 always have a parent frame; consider a function called directly
3058 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
3061 * alloca.c (alloca): Undo yesterday's changes, and simply call
3062 malloc directly for storage, and abort if we don't get what we
3063 want. The situation is much simpler --- just call malloc. Emacs
3064 has bizarre/evil requirements (signal handlers might malloc unless
3065 you set this global flag, so you have to set the flag around all
3066 calls to malloc) which we are certainly not going to conform to,
3067 so we can do the simple and obvious thing.
3069 * coop.c (coop_condition_variable_wait): Make this function
3070 static. It's only useful internally --- you should never just
3071 wait on a condition variable.
3072 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
3074 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3076 * unif.c (scm_array_set_x): Accept any kind of number as an
3077 element for a uniform vector of doubles. This is more consistent
3078 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
3080 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
3081 works; I can't conveniently test it myself. (Thanks to Dvid
3082 Tillman for the bug report.)
3084 * init.c: Doc fixes.
3086 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
3087 from here, not from scm_compile_shell_switches (which is a pretty
3088 dumb place to do it).
3089 (scm_load_startup_files): New function.
3090 (scm_ice_9_already_loaded): Variable moved to here from script.c.
3091 * script.c (scm_compile_shell_switches): Don't load the startup
3093 (scm_ice_9_already_loaded): Variable moved.
3094 * init.c (scm_load_startup_files): Prototype for new function.
3095 * gh_init.c (gh_enter): Doc fix.
3097 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3099 Some anti-warning changes from Greg Harvey.
3100 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
3101 warnings when it doesn't understand our NORETURN declarations in
3103 * posix.c (scm_mknod): Similar.
3105 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3107 * posix.c (scm_getpwuid): If we can't find an entry, return our
3108 own message, instead of using scm_syserror --- the getpwMUMBLE
3109 functions don't set `errno' to anything interesting.
3111 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3113 Get rid of warnings from the cooperative threading system.
3114 * threads.h (scm_single_thread_p, scm_yield,
3115 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
3116 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
3117 scm_wait_condition_variable, scm_signal_condition_variable): Add
3118 prototypes for these Scheme-visible functions.
3119 * coop-defs.h (coop_next_runnable_thread,
3120 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
3121 Prototypes for these here, even though they're from iselect.c.
3122 (coop_condition_variable_wait, coop_join): Add prototypes.
3123 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
3124 scm_threads_free_condvar): Make these smob functions static.
3125 * coop-threads.h (coop_init): Give this a real prototype.
3126 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
3127 (coop_next_runnable_thread): No need to provide prototype; it's in
3130 * scmconfig.h.in: .detarenegeR
3132 * iselect.c, threads.c: Doc fixes.
3134 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3136 * Makefile.in: Regenerated with a patched automake, to get
3137 dependency generation right when using EGCS.
3139 * inet_aton.c (inet_aton): Add prototype, to remove compiler
3140 warning. (Thanks to Robert Pluim.)
3142 * inet_aton.c (inet_aton): Reassure the compiler that the
3143 arguments to the <ctype.h> macros are all unsigned characters, not
3146 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3148 Getting rid of more warnings...
3149 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
3150 today's change to ../configure.in.
3151 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
3152 * scmconfig.h.in: Regenertaded.de.,.__
3153 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
3154 (scm_localtime, scm_mktime): Use a const char * to manipulate the
3157 * readline.c: Doc fix.
3158 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
3159 * readline.h (scm_filename_completion_function): Add prototype.
3160 (scm_init_readline): Make this into a prototype.
3162 * readline.c (scm_filename_completion_function): Use SCM_PROC to
3163 declare this, instead of calling scm_make_subr manually.
3165 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
3167 * readline.h (scm_init_readline): Add prototype for this.
3168 (scm_init_readline): Make this a real prototype.
3170 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3172 Warning fixes from Maciej Stachowiak:
3173 * backtrace.h (scm_display_application, scm_backtrace): Add
3175 * debug.c (scm_m_start_stack): Make this function static.
3176 * fluids.h (scm_fluid_p): Add prototype.
3177 * procprop.c (scm_i_procedure_arity): Make this function static.
3178 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3179 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
3180 * root.h (scm_dynamic_root): Add external prototype.
3181 * scmsigs.h (scm_usleep): Add external prototype.
3182 * script.h (scm_init_script): Use prototype, not K&R decl.
3183 * stacks.h (scm_stack_id): Add external prototype.
3184 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3186 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3188 * gh.h: took out the definitions of vset and vref, since they are
3189 replaced by the proper vector routines that correspond to the R4RS
3192 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3194 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3195 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3196 third argument, a C expression that should result in a SCM value,
3197 which is used to initialize the variable. Reimplemented
3198 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3201 * version.h (scm_libguile_config_stamp): Add prototype.
3202 (From Maciej Stachowiak.)
3204 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3206 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3207 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3209 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3211 * print.c (scm_iprin1): Rather than having one i, and using it in
3212 several places, declare a fresh i local to each block where it is
3213 used, and give it a signedness appropriate to its use in each case.
3214 (scm_iprlist): Same.
3216 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3217 comparison warnings.
3219 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3220 signed/unsigned clashes.
3222 * posix.h (scm_tmpnam): Added prototype.
3224 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3225 scm_make_subclass_object): Add external prototypes.
3227 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3228 comparison is okay here.
3230 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3232 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3233 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3235 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3238 * load.c (swap_port): Make this function static.
3240 * load.c (scm_search_path): Make max_path_len and max_ext_len
3241 unsigned, since they're compared against string sizes.
3243 * load.c (init_build_info): Make i unsigned.
3245 * ioext.h (scm_read_line): Add prototype.
3247 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3248 scm_hash_fn_remove_x): Make hash bucket index local variable k
3249 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3250 accurately as possible.
3252 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3253 comparisons, and range checking to make sure those casts are
3256 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3257 signed/unsigned comparisons.
3259 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3260 avoid signed/unsigned comparisons.
3261 * smob.h (scm_numsmob): Change extern declaration to match.
3263 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3264 avoid signed/unsigned comparisons.
3265 * ports.h (scm_numptob): Change extern declaration to match.
3266 (scm_current_load_port, scm_set_port_line_x,
3267 scm_set_port_column_x): New prototypes.
3269 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3270 test code, and it causes warnings.
3272 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3273 gh_uniform_vector_ref): Added prototypes.
3275 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3276 debugging support unconditionally. That's backtrace.c, stack.c,
3277 debug.c, and srcprop.c.
3278 (EXTRA_libguile_la_SOURCES): Omit those from here.
3279 * Makefile.in: Regenerated.
3281 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3283 * options.c (scm_options): Bugfix: Allow empty list of options!
3285 * debug.c, debug.h (scm_single_step): Removed.
3286 (scm_with_traps): New procedure. This procedure could easily be
3287 written in Scheme but needs to be highly optimized.
3289 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3291 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3292 Check SCM_TRAPS_P before trapping.
3294 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3296 Changes to avoid signed/unsigned comparison warnings.
3297 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3298 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3299 so they can have appropriate types for each application. Make i
3300 signed. Use initializers in some spots. I'll probably pay for
3302 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3303 (scm_must_realloc): Make nm unsigned.
3304 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3305 (scm_init_storage): Use prototype-style definition, and make the
3307 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3308 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3310 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3311 avoid signed/unsigned comparison warnings, and because the return
3312 value of readlink may be -1. Don't bother casting the third
3313 argument to readlink.
3315 * filesys.c (scm_dirname, scm_basename): Move these to their own
3316 page, at the end of the file.
3317 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3319 * eval.h (scm_eval_options_interface): Add external prototype for this.
3320 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3322 * eval.c (scm_lookupcar1): Make this static.
3324 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3325 Make these prototype declarations, not K&R-style.
3327 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3328 unsigned comparison warning.
3330 * appinit.c: File removed. It had a single function in it, empty,
3331 whose reason for existence is explained in no documentation or
3332 comment. I think it's there as a default for some Tcl-style
3333 initialization, but Tcl abandoned that approach a while ago.
3334 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3335 (BUILT_SOURCES): Remove appinit.x.
3336 * Makefile.in: Regenerated.
3338 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3340 * Makefile.in: Regenerated using the last public version of
3341 automake, not the hacked Cygnus version.
3343 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3345 Remove Totoro kludge.
3346 * Makefile.in, scmconfig.h.in: Regenerated.
3347 * init.c, readline.c: Don't check if TOTORO is #defined.
3349 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3351 * Makefile.am: Adjust for new thread configuration system.
3352 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3353 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3355 (THREAD_LIBS): Definition deleted; automake will generate such
3356 things automatically.
3357 * Makefile.in: Regenerated.
3359 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3361 Simplify smob and port marking; set the mark bit in the generic
3362 marking code, and make marker routines only responsible for
3363 turning up outgoing pointers.
3364 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3365 before calling the marking function. Don't call the marking
3366 function if it's zero.
3367 * markers.c (scm_mark0): Just return #f. This function isn't
3368 necessary at all now, but it's harmless to call it. We'll leave
3369 it in so other folks' code doesn't croak at link time.
3370 (scm_markcdr): Don't call SCM_SETGC8MARK.
3371 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3372 * dynl.c (mark_dynl_obj): Same.
3373 * root.c (mark_root): Same.
3374 * srcprop.c (marksrcprops): Same.
3375 * unif.c (markra): Same.
3376 * variable.c (scm_markvar): Same.
3377 * ports.c (scm_markstream): Same.
3378 (void_port_ptob): Specify zero for our marking function.
3379 * debug.c (debugobjsmob): Same.
3380 * dynwind.c (guardsmob): Same.
3381 * filesys.c (dir_smob): Same.
3382 * fluids.c (fluid_smob): Same.
3383 * fports.c (scm_fptob, scm_pipob): Same.
3384 * mallocs.c (mallocsmob): Same.
3385 * regex-posix.c (regex_t_smob): Same.
3386 * smob.c (freecell, flob, bigob): Same.
3387 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3388 * throw.c (jbsmob, lazy_catch_funs): Same.
3390 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3392 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3393 scm_copy_tree on code in order not to let memoized code to leak
3394 out. Thus, scm_copy_tree needs to copy vectors as well since
3395 quasiquote can introduce evaluated code also inside vector
3398 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3400 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3402 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3403 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3406 * unif.c: Say that ivect and uvect are of type signed and unsigned
3407 long instead of int in commentary so that it correctly describes
3410 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3412 * stime.c: Removed declaration of strptime. (It should be
3413 declared by the system headers. If it turns out that some systems
3414 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3416 * stime.h: Renamed TIMEH --> STIMEH
3418 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3419 to increase portability, don't use structure assignment.
3420 (Thanks to Nicolas Neuss.)
3422 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3424 (finalize_fd_sets): Added empty statement after last case label.
3425 (Thanks to Nicolas Neuss.)
3427 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3430 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3432 * init.c, readline.c: OK, I won't have these readline.x bug
3433 reports anymore. We've had them since April. The current reason
3434 is a completely unintelligible failure of totoro.red-bean.com to
3435 do the test for rl_getc_function in libreadline correctly. This
3436 kludge overrides the test if we're on totoro so that the snapshot
3437 generation process can work.
3439 * readline.c: Define a strdup replacement if not existent on system.
3441 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3443 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3444 This change makes scm_make_vector R5RS compatible. We cannot keep
3445 the third argument since people want to be able to deduce the form
3446 of the C function call only by looking at R5RS. (At the same time
3447 we have removed some unnecessary complexity!)
3449 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3450 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3451 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3452 argument in call to scm_make_vector.
3454 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3456 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3457 This macro is useful in applications.
3459 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3461 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3462 (scm_parse_path, scm_search_path): New Scheme level procedures.
3464 * load.h (scm_internal_parse_path, scm_parse_path,
3465 scm_search_path): Declared.
3467 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3469 * filesys.c (dirname, basename): New procedures.
3471 * init.c (scm_boot_guile_1): Removed condition around
3474 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3475 new data type (guards) for representation of C level guards and
3476 data on the wind chain.
3477 (scm_internal_dynamic_wind): New function.
3479 * dynwind.h: Declare scm_internal_dynamic_wind.
3481 * root.h (scm_root_state): Added scm_cur_loadp.
3483 * root.c (mark_root): Added comment about cur_loadp.
3485 * load.c: #include "dynwind.h";
3486 (scm_primitive_load): Use scm_inner_dynamic_wind to update
3489 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3491 * ports.c (current-load-port): New procedure.
3493 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3495 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3496 not a tty, return #f.
3498 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3499 to Julian Satchell and Roland Kaufmann.)
3501 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3502 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3504 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3506 * debug.h, debug.c (scm_start_stack): New function. Implements
3507 the guts of old scm_m_start_stack.
3509 * debug.c (scm_m_start_stack): Use scm_start_stack.
3511 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3512 start_stack and restart_stack. (These have static scope.)
3514 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3516 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3517 readline functions to come in release 2.3. (Thanks to Chet
3519 (handle_errors): Use the above functions.
3521 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3523 * readline.c: Improvements for readline support: Handle errors
3524 better; Implement before-read-hook.
3526 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3528 * init.c (scm_boot_guile_1), readline.c: Test for
3529 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3530 assure that we have version >= 2.1.)
3532 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3534 * readline.c (scm_readline): Defer interrupts while we're calling
3537 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3538 away the string to add_history.
3539 (completion_function): Do completion for readline. (Thanks to
3541 (scm_filename_completion_function): New procedure: Filename
3543 (current_input_getc): New function. Use this one instead of
3544 standard getc from readline.
3546 * throw.c, throw.h (scm_handle_by_throw): New function: This
3547 handler throws errors to next handler on the dynwind chain.
3549 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3551 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3554 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3556 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3558 (scm_procedure_properties): Modified to return arity together with
3560 (scm_procedure_property): Added the read-only property `arity'.
3561 (scm_set_procedure_property_x): It is an error to set the `arity'
3564 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3565 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3567 * procprop.h (scm_sym_arity): New symbol.
3569 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3570 to set the dispatch procedure of an operator or entity object.
3572 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3573 Made procedure slots read-only.
3575 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3576 scm_tcs_cons_gloc case in zero args switch; Fixed args
3577 construction for operators in scm_tcs_cons_gloc case in two args
3580 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3582 * fluids.c: Removed use of assert.h (in order to avoid
3585 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3587 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3589 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3590 change makes the evaluator safer at the cost of evaluation speed.
3591 It handles the case when the user has added a non-immediate
3592 improper end of the application form, e.g., `(+ 0 . x)'.
3593 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3594 minimize the extra cost as much as possible. The new code is
3595 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3596 problem with structs planted directly in the code (e.g. by a
3597 macro). This no longer causes segmentation fault. (Thanks to
3600 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3601 arg `proc' in order to be able to throw errors; New argument
3604 * Removed extra #include "debug.h"
3606 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3608 * scmsigs.c: Declare usleep as returning void on some systems.
3609 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3612 * coop.c (usleep): Return void on some systems.
3614 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3616 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3618 * coop.c: Changed return type of usleep to int.
3620 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3621 isn't found in the OS.
3623 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3624 isn't enabled. (Thought that I had made this change ages ago...)
3626 * iselect.c: Declare bzero if not defined by OS.
3628 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3630 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3631 condition. (Thanks to John Tobey.)
3633 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3634 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3637 * __scm.h: Start the long-term project of moving to POSIX threads.
3638 Phase 1: Classification of all critical sections.
3639 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3640 for A sections. (See comments in __scm.h for details.)
3642 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3643 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3645 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3647 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3648 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3649 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3650 dependencies on $(srcdir)/Makefile.in
3651 $(top_builddir)/config.status in order to avoid circularity.
3653 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3654 from argc if argc was 0 initially.
3656 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3657 in generation of libpath.h.
3659 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3661 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3662 libguile from 2 to 3.
3664 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3666 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3668 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3670 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3671 scm_set_port_column_x, scm_port_filename,
3672 scm_set_port_filename_x): Removed optional arguments. Added
3673 proper argument checking.
3675 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3676 stack size in machine words.
3678 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3679 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3680 to Ole Myren Röhne.)
3682 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3684 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3685 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3687 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3690 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3691 procedure apply: Copy argument lists before pushing them unto the
3692 environment so that the environment won't get mutated due to
3693 manipulation of procedure arguments. This should perhaps be
3694 regarded as a temporary solution until someone finds a more
3695 efficient one. (Thanks to Maciej Stachowiak.)
3697 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3699 * script.c (scm_compile_shell_switches): Use "guile" as default
3700 zero arg if argc is NULL.
3702 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3704 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3705 is zero. (Thanks to Dirk Herrmann.)
3707 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3709 * ports.c (scm_add_to_port_table): First line is now line 0
3710 (was 1). (Interface changed according to suggestion by Per
3713 * backtrace.c (display_header): Add 1 to line and column numbers
3714 when presenting them to the user.
3716 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3717 from debug.c --> eval.c
3719 * eval.h, eval.c (scm_eval_options_interface): New options
3721 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3722 i.e. stacks for new threads.
3724 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3726 * eval.c (unsafe_setjmp): Removed with #if 0.
3728 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3731 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3732 to avoid compiler warnings.
3734 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3736 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3738 * throw.c (handler_message): Print message on current error port
3739 instead of default error port. (Thanks to Maciej Stachowiak.)
3741 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3743 * ports.c (scm_add_to_port_table): allocate in units of
3744 struct scm_port_table *, not struct scm_port_table.
3745 * posix.c (scm_close_pipe): remove the port from the port table
3747 Thanks to Rob Engle for both fixes.
3749 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3751 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3752 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3754 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3756 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3758 * backtrace.c (display_error_body, display_backtrace_body),
3759 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3760 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3761 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3762 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3765 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3766 don't receive the jmpbuf arg anylonger.
3767 (scm_catch): Don't accept a #f tag.
3768 (scm_throw): Check that key is a symbol.
3769 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3771 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3773 * async.c (async_pending): Removed declaration.
3775 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3777 * dynwind.c (scm_wind_chain): New debug function.
3779 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3780 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3781 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3782 extra layer of functions around the body and handler of a thread.
3783 This extra layer makes sure that the handler is called in the
3784 dynamic context of the surround (= empty dynwind list), but under
3785 the *dynamic root* of the body. We can not use the dynamic root
3786 of the surround since that root belongs to another thread => stack
3787 is not handled correctly. It may seem ugly to use this extra
3788 layer, but the extra cost in terms of execution time is really
3789 negligible compared to the total amount of time required to create
3790 a thread, and it would reduce maintainability to duplicate the
3791 crucial and complicated steps performed by cwdr.
3793 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3794 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3795 get re-enabled. The important effect of this is that interrupts
3796 are blocked during thread switching so that thread data structures
3797 don't risk getting messed up by an unfortunate signal.
3798 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3799 seems to do more aggressive optimization which actually move
3800 instructions around in these macros in a fatal way. Therefore:
3801 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3802 just superstitious...)
3803 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3804 This macro should be used instead of SCM_ASYNC_TICK since the
3805 latter doesn't do context switches any more.
3807 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3808 instead of SCM_ASYNC_TICK.
3810 * coop.c, iselect.c: Since thread switches are now performed with
3811 interrupts masked, we can't use the old mechanism of delivering
3812 signals immediately when they arrive. Signals must instead be
3813 delivered when the asyncs run *after* the end of the critical
3814 section in scm_internal_select. But this also means after context
3815 switch so that the signal will be delivered to a different thread.
3816 To avoid this, I have changed the protocol of
3817 coop_wait_for_runnable_thread and friends so that they are allowed
3818 to return the original thread. So, if a signal arrives during
3819 scm_internal_select, we won't any longer be forced do a context
3820 switch, but can remain in the same thread and deliver the signal
3823 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3824 scm_asyncs_pending and made it global.
3826 * iselect.c: Small fixes.
3828 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3829 coop_condition_variable_init, coop_condition_variable_wait,
3830 coop_condition_variable_signal): Changed return type from `void'
3831 to `int'. This is to adhere closer to the pthreads interface.
3832 This, in turn, is part of an attempt to provide C versions of the
3833 mutex and condition variable primitives which can be part of a
3834 frontend to COOP or pthreads.
3836 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3837 coop_condition_variable_destroy): New functions.
3839 * coop-threads.c (scm_wait_condition_variable): Use
3840 coop_condition_variable_wait_mutex.
3842 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3843 Definitions moved to coop-defs.h.
3845 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3846 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3847 scm_cond_destroy): New C interface to mutecis and cond vars.
3849 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3851 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3853 * iselect.c: Now several threads can wait on the same file
3854 descriptor. The behaviour is compatible with OS select: All
3855 threads waiting for the fd return with the same status.
3857 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3859 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3860 Can spawn a thread from application C code.
3862 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3864 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3865 gh_doubles2scm): New functions.
3867 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3869 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3870 commented-out version of gh_eval_str()
3872 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3874 * socket.c (scm_bind): free soka after use.
3876 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3878 * stime.c (tzvar): new variable.
3879 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3880 avoid memory leaks when allocating.
3882 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3884 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3887 * gc.c, tags.h: Doc fixes.
3889 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3891 * eval.c (macro-eval!): Removed. This function was a design bug.
3892 It allowed memoized code to leak out to the scheme level. Most
3893 things that you could do with `macro-eval!' can be done with
3896 1997-12-20 Tim Pierce <twp@skepsis.com>
3898 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3899 scm_fgets now depends on ftell(3) to know how many bytes were
3902 1997-12-15 Tim Pierce <twp@skepsis.com>
3904 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3905 dealing with strings.
3907 1997-12-13 Tim Pierce <twp@skepsis.com>
3909 Make %read-line more suitable for implementing read-line efficiently.
3910 * ioext.c (scm_read_line): Strip the terminating newline from a
3911 string, and return a cons of the string and its terminator.
3913 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3914 of the string that is read is stored in this memory location.
3915 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3916 * genio.c, genio.h (scm_do_read_line): Update caller.
3917 * ports.h (scm_ptobfuns): Update typedef.
3918 * fports.c (scm_fptob, scm_pipob): Update struct.
3920 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3922 * filesys.c (set_element): Return file descriptor.
3923 (fill_select_type): Return the highest file descriptor.
3924 (scm_select): Tell select about the highest file descriptor. On
3925 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3926 Therefore the extra overhead for calculating the maximum fd seems
3927 to be more than compensated. Is this correct? In any case,
3928 scm_internal_select will be much faster with this info.
3929 (scm_select, fill_select_type, set_element): Don't accept any kind
3930 of object in the file descriptor list or vector.
3932 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3934 * iselect.c (finalize_fd_sets): Bugfix.
3936 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3938 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3939 when using scm_internal_select (since we might switch to another
3942 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3944 * simpos.c (scm_system): always define: use sysmissing if not
3945 available. Check for HAVE_SYSTEM instead of _Windows (does
3946 Windows lack system or does it have an unusable one?).
3947 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3948 Let the argument be optional: if not supplied, call system(NULL).
3950 * ports.c (scm_close_port): relax the type check from OPPORTP to
3951 PORTP; closing a closed port is allowed.
3953 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3955 * fports.c (scm_fgets): Return if the last char in a chunk is
3956 newline. When fgets returns a string whose length is `size-1', it
3957 is ambiguous whether a whole line was retrieved, so we must check
3958 explicitly whether a line terminator is present.
3960 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3962 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3963 before taking the CDR. (Thanks to Harald Meland.)
3965 * filesys.c (scm_stat): Slightly optimized.
3967 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3969 * ports.c (scm_close_port): Make sure the port is open before
3972 * guile-snarf.in: Pass args through to gcc in a way that preserves
3973 whitespace boundaries. (Thanks to Greg Badros.)
3975 1997-12-02 Tim Pierce <twp@skepsis.com>
3977 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3978 statement. (Thanks to Doug Evans for pointing this out.)
3980 1997-12-01 Tim Pierce <twp@skepsis.com>
3982 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3984 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3986 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3987 errno macro expansion of this field name. (errno is a C
3988 preprocessor macro on some systems.)
3990 1997-11-29 Tim Pierce <twp@skepsis.com>
3992 * iselect.c: Doc fix.
3994 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3996 * init.c (scm_start_stack): Removed initialization of
3997 scm_the_last_stack_var.
3999 * backtrace.h: Declare scm_the_last_stack_var.
4001 * backtrace.c: Define scm_the_last_stack_var.
4003 * root.c (mark_root): Don't mark the_last_stack_var.
4005 * root.h (scm_root_state): Removed the_last_stack_var.
4007 * throw.c: Added #include "fluids.h"
4008 (ss_handler): `the-last-stack' is now a fluid.
4010 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
4011 --> the_last_stack_fluid.
4013 * backtrace.c: Added #include "fluids.h"
4014 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
4015 (scm_backtrace): `the-last-stack' is now a fluid.
4017 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
4018 after scm_init_fluids.
4020 1997-11-28 Tim Pierce <twp@skepsis.com>
4022 * iselect.c: #ifdef USE_THREADS around thread-related includes.
4024 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
4025 DLSYM_ADDS_USCORE to decide whether to add an underscore.
4027 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4029 * iselect.c (coop_next_runnable_thread,
4030 coop_wait_for_runnable_thread): Disable interrupts so that no
4031 async is executed before a potential error_revive.
4032 (scm_internal_select): Disable interrupts during the parts of the
4033 code which manipulate the sleep queue and the file descriptors.
4035 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4037 * Makefile.am: Added iselect.c and iselect.h.
4039 * coop.c (coop_qinit): Initialize fields used by
4040 scm_internal_select.
4041 (coop_qget, coop_qget, coop_tmp_queue): Made global.
4042 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
4043 replacement in iselect.c.
4044 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
4045 coop_join): If GUILE_ISELECT enabled, use
4046 coop_wait_for_runnable_thread instead of
4047 coop_next_runnable_thread.
4048 (usleep, sleep): New replacements for system functions if
4049 GUILE_ISELECT is enabled.
4051 * coop-threads.h: Declare coop_wait_for_runnable_thread.
4053 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
4055 * filesys.c: Added #include "iselect.h". Moved FD-macros to
4056 iselect.h. Implement Scheme level `select' using
4057 scm_internal_select. (See NEWS.)
4059 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
4061 * init.c: Call scm_init_iselect.
4063 * iselect.h, iselect.c: New files. Implements
4064 scm_internal_select. (See NEWS.)
4066 1997-11-27 Tim Pierce <twp@skepsis.com>
4068 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
4069 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
4070 and scm_must_free, since ultimately the string returned will be copied
4071 by scm_makfrom0str anyway. Also, read any characters that may have
4072 been pushed onto the port with scm_ungetc.
4073 * ports.c (scm_generic_fgets): Same as for scm_fgets.
4074 * ioext.c (scm_read_line): Free string after Guilifying it.
4075 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.

4086 gh_repl (argc, argv).
4088 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
4090 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
4091 and to invoke scm_shell().
4092 (gh_launch_pad): took out the loading of boot-9.scm from here,
4093 since it is probably best to let the user control that. In fact,
4094 gh_repl() now invokes scm_shell() which does that.
4096 1997-11-23 Mark Galassi <rosalia@cygnus.com>
4098 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

4115 (gh_uniform_vector_ref): started implementing the uniform types in
4118 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
4120 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
4121 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
4123 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
4125 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
4126 configure.in was changed).
4128 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
4130 * Makefile.am (modinclude_HEADERS): Include readline.h here.

4133 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
4135 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
4136 OPORT is an `open' port, not an output port.
4138 * filesys.c (scm_close, set_element, get_element, scm_chown,
4139 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

4144 scm_set_port_filename_x, scm_port_mode,
4145 scm_close_all_ports_except, scm_set_current_output_port,
4146 scm_set_current_error_port): Likewise
4147 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
4148 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
4150 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
4151 * backtrace.c (display_backtrace_body): Likewise
4152 * fports (scm_setvbuf): Likewise
4153 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

4160 Minor problems with substring-related tag changes.
4161 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
4162 exactly what we want to leave in to detect substrings.
4163 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
4164 * tags.h: Fix diagrams and comments describing the S tag bit;
4165 remove vestigial remarks about the D tag bit.

4167 * strings.c: Formatting tweaks.
4169 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
4170 variable first; then SCHEME_LOAD_PATH, with a warning message.
4171 (scm_parse_path): New function.
4172 * script.c: Doc fixes.
4174 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
4176 Readline support, from Daniel Risacher.
4177 * readline.c, readline.h: New files.
4178 * init.c: #include "readline.h".
4179 (scm_boot_guile_1): Call scm_init_readline, if we have it.
4180 * Makefile.am (libguile_la_SOURCES): Include readline.c.
4181 * Makefile.in: Regenerated.
4182 * scmconfig.h.in: Regenerated, after change to ../configure.
4184 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4186 * gh.h: gh_vector_set -> gh_vector_set_x
4188 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4190 * gh_data.c (gh_vector_set_x): changed name to make it consistent
4191 with the ! -> _x mapping when going from Scheme to C.
4193 1997-10-19 Mark Galassi <rosalia@cygnus.com>
4195 * gh.h (gh_reverse):
4203 (gh_assoc): added these gh_ functions implemented as macros.
4205 * gh_predicates.c (gh_null_p):
4206 (gh_string_equal_p): added these two missing predicates.
4208 * gh_list.c (gh_append):
4213 (gh_set_cdr_x): added these routines as I go through and try to
4214 complete the picture R4RS functions that should be mirrored in the
4217 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4219 * tags.h (scm_tc7_substring): Changed the comment and code to
4220 conform with the changes below. Folks! We have suddenly two new
4221 free tc7 codes!!! Jummy, jummy!
4223 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>

4246 (scm_tc7_mb_string): Removed.
4247 (scm_tc7_mb_substring): Removed.

4251 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
4252 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
4254 Don't include "mbstrings.h".
4255 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
4256 (SCM_SYMBOL_SLOTS): Define as 4.

4259 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
4260 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
4261 struct.c, threads.c, throw.c, unif.c, variable.c: Use new

4281 1997-10-12 Mark Galassi <rosalia@cygnus.com>
4283 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
4285 * gh_test_c.c (c_vector_test): some improvements on the vector
4288 * gh.h (gh_vector): this used to exist but do the wrong thing.
4289 Now it (almost) does the right thing, though it takes a list
4290 instead of the individual arguments. I need to see how it could
4292 (gh_list_to_vector): added this function as a macro. Corresponds
4293 to Scheme's (list->vector ...).
4294 (gh_vector_to_list): added this function as a macro. Corresponds
4295 to Scheme's (vector->list ...).
4297 * gh_data.c (gh_vector_ref): renamed from gh_vref to
4298 gh_vector_ref, so that it resembles the Scheme routines more.
4299 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
4300 resembles the Scheme routines more.
4301 (gh_make_vector): this used to be (stupidly) called gh_vector().
4302 This is the right name, since it does the same thing as the Scheme
4303 (make-vector ...) procedure.
4305 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4307 * ports.h: #include "libguile/print.h"

4310 Some indentation fixes.
4312 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
4313 longer a user field; New field: class_flags.
4315 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
4317 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
4319 * gh_data.c (gh_bool2scm): new function which replaces
4320 gh_int2scmb(), which is now tagged as obsolete.
4322 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4324 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4325 macros should by convention not test for NIMPness.)
4326 (SCM_COERCE_OPORT): Adjust indentation.
4328 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4329 SCM_NIMP test before SCM_PRINT_STATE_P.
4331 * struct.c, struct.h, gc.c: Renamed:
4332 scm_struct_i_layout --> scm_vtable_index_layout
4333 scm_struct_i_vcell --> scm_vtable_index_vcell
4334 scm_struct_i_vtable --> scm_vtable_index_vtable
4335 scm_struct_i_printer --> scm_vtable_index_printer
4336 scm_struct_i_vtable_offset --> scm_vtable_offset_user
4338 * struct.c (scm_print_struct): Use new printer slot; Default
4339 printing: Also output hex code of vtable so that type identity
4340 will be indicated as well.
4341 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4342 Removed struct_printer_var; Removed struct-vtable-offset;
4343 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4344 vtable-offset-user): New constants.
4346 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
4347 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
4348 If this slot contains a procedure, use that to print structures of
4349 the type represented by this vtable.
4351 * print.c (scm_iprin1): Don't print arguments of macro
4352 transformers. (They are always: exp env.); Bugfix: Unmemoize
4353 transformer source with correct environment.
4355 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4357 Streamlining of call-with-dynamic-root:
4359 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
4360 there is now only one catch.
4361 (cwdr_outer_body): Removed.
4362 (cwdr_handler): New function.
4363 (scm_internal_cwdr): New function to perform the function of cwdr
4364 but take args that are more useful to C code. Also, the handler
4365 is now invoked *outside* of the new dynamic root, like the docs
4366 say. We no longer have to catch absolutely all errors, the caller
4367 is responsible for using a handler that does not throw, if he
4369 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4370 * root.h (scm_internal_cwdr): New prototype.
4372 Even more but risky streamlining:
4374 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4375 allocation of the jumpbuf of a root continuation. The changes
4376 below are controlled by it. They are now deactivated.
4377 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4378 the JMPBUF of the scm_rootcont to NULL before returning.
4380 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4381 when they are non-NULL.
4382 (scm_gc_mark): Likewise, mark only when non-NULL.
4384 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4385 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4387 * gc.c (scm_done_malloc): New function.
4388 gc.h (scm_done_malloc): New prototype.
4390 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.

4397 a certain value is acceptable as a port argument.
4398 (scm_print_state_vtable): New variable.
4399 (scm_free_print_state): Set `revealed' field to false.
4400 (scm_iprin1): Call user supplied closure printer with
4401 scm_printer_apply. Print in the traditional way when there isn't
4402 one or when it returns #f.
4403 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4404 Accept a port/print-state pair in addition to just a port.
4405 (scm_prin1): Don't return the print_state to the pool when it has
4407 (scm_printer_apply): Set `revealed' field of print_state to true.
4408 (scm_init_print): Set scm_print_state_vtable.
4409 (print_state_fluid, print_state_fluid_num): Removed.
4411 * throw.h (scm_handle_by_proc_catching_all): New prototype
4412 throw.c (scm_handle_by_proc_catching_all): New function
4414 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4416 * Makefile.in: Regenerated with automake 1.2c.
4418 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4420 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4421 was looping endlessly.
4423 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4425 * strports.c (scm_eval_string): Don't close the port.
4427 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4428 former returns a nice normal integer. (Thanks to Daniel
4431 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4433 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4434 makefile variable as a build parameter called LIBS. The
4435 build-guile program will use this, for the time being.
4436 * Makefile.in: Regenerated.
4438 Thanks to Shiro Kawai:
4439 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4440 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4443 * Makefile.in: Regenerated with automake 1.2a.
4445 * script.c (scm_compile_shell_switches): If we hit the -c or --
4446 arguments, don't set the car of (command-line) to scm_usage_name,
4447 the prettified name of the guile executable; give it the full
4448 path, the way shells usually handle $0.
4450 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4452 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4453 Scheme-level name `array-map' and renamed `serial-array-map' to
4454 `serial-array-map!'.
4456 * backtrace.c: Introduced exception handlers which now enclose
4457 `display-error' and `display-backtrace' so that error reporting
4458 won't get into infinite loops if an error occurs during displaying
4459 of the error. This can very easily happen with user supplied
4460 print call-back routines.
4462 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4464 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4465 the names `serial-array-map' and `array-map' should be removed.)
4467 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4469 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4470 Added #include "objects.h"
4472 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4473 Add #include "feature.h".
4475 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4476 (modinclude_HEADERS): Added objects.h.
4478 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4479 This test is needed at many places in the code and should be
4480 abstracted. (Motivated by the need of this test in libguiletk.)
4482 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4483 (scm_eval_string), load.c (scm_primitive_load,
4484 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4485 Use SCM_EOF_OBJECT_P.
4487 * eval.c (scm_init_eval): Add feature `delay'.
4489 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4491 * scmhob.h: Removed.
4493 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4495 * list.h (SCM_LISTn): New macros. Make list creation in C code
4496 prettier. The idea comes from STk.
4498 * sequences.h, sequences.c, append.h, append.c: Removed. These
4499 files implemented non-R4RS operations which would encourage
4500 non-portable programming style and less easy-to-read code.
4502 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4505 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4506 sequences.h, #include append.h.
4508 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and

4513 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4515 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4517 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4519 * eval.c: Added #include "objects.h"
4521 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4524 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4525 adjacent smob numbers.
4527 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4529 * procprop.h: Added declaration of scm_i_inner_name.
4531 * gsubr.c: New global symbol scm_i_inner_name.
4533 * debug.c (scm_procedure_name): Try procedure property
4534 `inner-name' if `name' fails.
4536 * print.c (scm_iprin1): Use scm_macro_name.
4538 * eval.c (scm_m_define): Give names to macros as well; Only the
4539 first top-level definition gives a procedure/macro a name.
4540 Otherwise confusing names can turn up in backtraces.
4541 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4542 `name'; Give names to macros as well.
4544 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4545 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4548 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4550 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4552 (prinmacro): Removed. The code has been moved/merged into print.c
4553 in order to decrease code redundancy. We want macros to print in
4554 a way equivalent to procedures, and it would be silly to duplicate
4555 the required code. (We don't want to maintain two places.)
4556 (macrosmob): Print field is now a NULL pointer.
4558 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4559 scm_macro_transformer): New prototypes.
4560 (scm_tc16_macro): Declared.
4562 * print.c (scm_iprin1): Added code for printing of macros. Macros
4563 are now printed in a way equivalent to procedures.
4565 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4567 * procs.h (scm_closure_p): Added declaration.
4569 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4571 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4572 Shouldn't pass "heap" as the subr name.
4574 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4576 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4577 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4578 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4579 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4580 SCM_BOOL_T. Any non-false value is true.
4582 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4584 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4585 scm_gensym): Added prototypes.
4587 * symbols.c (scm_gensym): New function. This will speed up
4588 certain types of applications (such as macro systems) which
4589 generate lots of symbols.
4591 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4593 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4595 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4597 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4598 specifier, since (2) or (2 . 3) would cause SEGV.
4599 (scm_transpose_array): more argument checking fixes.
4601 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4603 * Makefile.in: Regenerated.
4605 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4607 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4609 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4611 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4613 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4615 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4616 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4619 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4620 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4621 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4622 scm_array_p, scm_array_rank, scm_array_dimensions,
4623 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4624 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4625 scm_array_prototype): Added case scm_tc7_wvect.
4627 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4629 * errno.h: prototype for scm_strerror.
4630 * error.c (scm_strerror): new procedure.
4632 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4634 * list.c (scm_list_append_x): Allow non-pair as last argument.
4635 This is consistent with the R4RS append and is probably the
4636 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4638 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4640 * stime.h: prototype for scm_times.
4641 * stime.c (scm_times): new procedure.
4642 * ioext.c (scm_fseek): if the first argument is a file descriptor
4644 (scm_ftell): if the first argument is a file descriptor call lseek
4646 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
4647 * filesys.c (scm_chmod): if the first argument is a file descriptor,
4649 (scm_chown): if the first argument is a port or file descriptor,
4651 (scm_truncate_file): new procedure.
4652 Add DEFER/ALLOW INTS to a few other procedures.
4653 (scm_fsync): new procedure.
4654 (scm_open_fdes): new procedure.
4655 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
4657 (scm_fcntl): the first argument can now be a file descriptor. The
4658 third argument is now optional.
4660 * posix.c (scm_execl, scm_execlp): make the filename argument
4661 compulsory, since omitting it causes SEGV.
4662 (scm_sync): return unspecified instead of #f.
4663 (scm_execle): new procedure.
4664 (environ_list_to_c): new procedure.
4665 (scm_environ): use environ_list_to_c. disable interrupts.
4666 (scm_convert_exec_args): take pos and subr arguments and
4667 improve error checking.
4669 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4671 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4672 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4673 argument to SCM_ASSERT. Furthermore, the name of the function
4674 should be passed as first argument when signalling
4675 SCM_WNA. (Thanks to Thomas Morgan)
4677 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4678 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4679 dispatches on the number of actual args has a default case
4680 reporting an internal error. This is a vestige from a version
4681 that mallocated a SCM vector to hold the arguments. In the
4682 current version this check is too late: if it ever happens we will
4683 have already overstepped the bounds of the array.
4685 Also, the patch [...] adds a check for too many actual arguments."
4687 mdj: Removed check for "internal programming error".
4689 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4691 * gh_io.c (gh_write): New function.
4693 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
4694 throw.c (scm_internal_stack_catch): New sibling to the other catch
4695 functions. Code moved from gh_eval.c.
4696 throw.h: Added header.
4697 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
4698 scm_internal_stack_catch.
4700 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4702 * ioext.h: fix up prototypes.
4703 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
4704 Scheme name is now dup->fdes.
4705 (scm_dup_to_fdes): make the second argument optional and
4706 fold in the functionality of scm_primitive_dup.
4707 (scm_primitive_dup): deleted.
4709 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4711 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
4712 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4713 ultrix are defined. Use setvbuf instead of setbuf.
4714 (scm_setvbuf): new procedure.
4715 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
4716 (scm_setfileno): moved from ioext.c.
4717 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
4718 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.

4728 state as nested data while they are printed.
4729 (print_state_fluid, print_state_fluid_num): New variables.
4730 (scm_init_print): Initialize them.
4731 (scm_iprin): If print_state_fluid carries a print_state, use that
4732 instead of creating a new one.
4733 (scm_printer_apply, apply_stub, struct apply_data): New
4734 definitions to help with calling printer functions written in
4736 * print.h (scm_printer_apply): New prototype.

4749 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
4750 SCM_ASSERT: arg comes before pos.
4752 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4754 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
4755 to a list of length zero correctly.
4757 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

4773 * ioext.h: removed scm_duplicate_port prototype.
4775 * ioext.c (scm_primitive_dup2): return the new file descriptor
4776 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
4778 (scm_fdopen): bug fix: don't try to make port unbuffered until its
4779 stream has been set.
4780 (scm_duplicate_port): deleted, there's now an implementation in
4782 (scm_primitive_dup2): do nothing if newfd == oldfd.
4784 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
4786 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

4792 * fluids.c (next_fluid_num): don't do
4793 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
4795 * ports.h: prototypes too.
4796 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
4798 * fports.h: prototype too.
4799 * fports.c (scm_evict_ports): moved from ioext.c.
4801 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4803 * ports.c (scm_close_port): return a boolean instead of unspecified.
4804 throw an error if an error other than EBADF occurs.
4806 * filesys.h: scm_close prototype.
4807 * filesys.c (scm_close): new procedure, can close file descriptors
4808 and ports (scsh compatible).
4810 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
4813 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
4815 * fluids.c, fluid.h: New files.
4816 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
4817 (modinclude_HEADERS): Added "fluids.h"

4826 (scm_make_root): Call scm_copy_fluids to make fluid bindings
4827 unique for the new root when it has a parent.
4829 * smob.h: Include "libguile/print.h" to make scm_print_state
4832 * dynl.c (free_dynl_obj): New function to free the dynamic object
4833 data. (dynl_smob): Use it.
4834 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4835 the dynamic object data below the linking of the object to avoid
4836 memory leak when the linking code throws an error. Now the code
4837 leaks a whole dynamically linked library when must_malloc throws,
4838 but that should be much less likely.
4840 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4842 Changes to compile under gnu-win32, from Marcus Daniels:

4844 (scm_localtime): Change SCM_EOF to SCM_EOL.
4845 (scm_mktime): Likewise.

4858 (scm_setpwent): For setpwent.
4859 (scm_setegid): For setegid.
4860 * net_db.c (scm_inet_netof): Don't include unless support

4880 think this is left over from the (eq? '() #f) days.
4882 * read.c (recsexpr): Give this a dummy definition if
4883 DEBUG_EXTENSIONS isn't #defined.
4885 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
4887 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

4897 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
4898 alloca.lo will be included in @LIBLOBJS@. Something better than
4899 this should be possible.
4900 * Makefile.in: Regenerated.
4902 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4904 * simpos.h: prototype for scm_primitive_exit.
4905 * simpos.c (scm_primitive_exit): new procedure, terminates the

4908 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
4910 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
4911 argument and logior its components together, so the user doesn't
4912 have to do this explicitly. Also, if regexp/basic is supplied, then
4913 turn off REG_EXTENDED.
4914 (scm_init_regex_posix): New regexp/basic symbol.
4915 (REG_BASIC): #define this if it is not already present.
4917 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

4931 * Makefile.in: Regenerated.
4933 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
4934 flag; I don't think we support it.
4935 (scm_make_regexp): Make sure the user doesn't pass the
4938 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4940 (scm_init_regex_posix): Define constants for the REG_mumble flags;

4948 Makefile directory variables. Print a message, but don't print
4950 (versiondat.h): Print a message, but don't print all the commands.
4951 * load.c: #include "alist.h".
4952 (init_build_info): New function.
4953 (scm_init_load): Call it.

4956 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
4958 * root.c: Establish a reliable catch-all handler for the new root.
4959 After all the Scheme handler function might signal an error too,
4960 and we don't want to lose that.
4961 (cwdr_inner_body): Renamed from cwdr_body.
4962 (cwdr_outer_body): New function, to establish the user's handler,
4963 and pass control to cwdr_inner_body.
4964 (cwdr): Establish the reliable catch-all handler here, and pass
4965 control to cwdr_outer_body.
4966 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
4967 the user's handler through to cwdr_outer_body.

4974 across this. Only works on GCC. Otherwise, we hope for the best.
4975 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4976 the feeling that real thread systems will not need this...
4978 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4980 Try to detect when people are using one version of libguile and a
4981 different version of ice-9. People have been skewing things and
4982 sending in bug reports.

4988 * scmconfig.h.in, Makefile.in: Regenerated.
4989 * Makefile.in: Regenerated.
4991 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
4992 primitive definitions under their Scheme names.
4994 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4995 1:2. Helps avoid confusion between installed and uninstalled libs.
4997 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
5000 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
5001 backslash from definition; this should be used like: GDB_INTERFACE;
5003 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5005 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
5006 new port unbuffered until its stream has been set.
5008 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
5010 * ports.h: new prototype.
5011 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
5013 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
5015 Make things compile neatly under Sun's C compiler.
5016 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
5017 * extchrs.c (xmbtowc): Make the second arg a normal char, not
5018 unsigned, because that's what the ANSI function takes.
5019 * extchrs.h (xmbtowc): Corresponding change to prototype.
5020 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
5022 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
5023 argument plain char *.
5024 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
5026 * tag.c (scm_tag): Remove unreachable statement.
5027 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
5028 top of the word, it should be unsigned.
5030 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
5031 is defined, to avoid warnings; it's only used in the
5032 conflict-checking code. Which might go away anyway.
5033 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
5034 conditionals; put the label definition in an #if too, to stifle
5037 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
5038 ChangeLog-threads in the distribution.
5039 * Makefile.in: Regenerated.
5041 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5043 * guile-snarf.in: Changed regexp to support CPPs that insert
5044 whitespace between lexical tokens (which munges the `%%%' snarf
5047 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5049 * load.c (scm_init_load_path): Append $(datadir)/guile to
5050 %load-path, so modules do not have to be installed in Guile's
5051 current version directory.
5053 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
5055 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
5056 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
5057 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
5058 call the sysdep functions with deferred ints.
5059 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
5060 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
5061 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
5064 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
5067 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
5069 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
5071 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
5073 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
5076 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
5078 * eval.c (scm_lookupcar1): New procedure to cope with a race
5079 condition during lookup (when using threads).
5080 (scm_lookupcar): Implement in terms of scm_lookupcar1.
5081 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
5084 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
5086 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
5087 supplied. (Change from Tim Pierce.)
5089 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
5091 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
5092 23:47:01 1997" changelog: Slots are now initialized with `#f' by
5093 default and not `()'. `#f' is the canonical non-value in Scheme,
5096 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5098 * struct.c (struct_printer): New variable that holds a handle on
5099 the Scheme variable *struct-printer*. This variable can be set by
5100 Scheme code to override the printing of structures.
5101 (scm_print_struct): If struct_printer is set, call it. If it is
5102 not set, or returns #f, print the structure in the old fashion.
5103 Include "eval.h" for scm_apply.
5105 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
5107 * struct.c (scm_struct_ref, scm_struct_set_x): Use
5108 scm_struct_i_n_words to get the number of fields, not
5109 -scm_struct_n_extra_words.
5111 On the route to fancier struct printing:
5112 * struct.c (scm_print_struct): New function to print a structure.
5113 Include "genio.h" to support it. This function doesn't do
5114 anything interesting right now, but I think it should be here
5116 * struct.h: Include "print.h" and add prototype for
5118 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
5119 print structures ourself.
5121 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5123 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
5124 before applying the handler in case it doesn't return.
5126 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
5128 * scmsigs.h, async.h: updated.
5130 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
5133 * posix.c (scm_uname): interpret only negative values as an error.
5134 Solaris normally returns a positive value.
5136 * script.c (scm_compile_shell_switches): if we are not going into
5137 an interactive repl, set scm_mask_ints to zero so that asyncs can
5140 * simpos.c (scm_system): don't ignore/unignore signals around
5143 * posix.c (scm_open_pipe): don't ignore/unignore signals around
5146 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
5147 done in boot-9.scm instead.
5149 * scmsigs.c, async.c: Major rewriting of signal handling code.
5150 (scm_sigaction): new procedure.
5151 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
5153 (scm_raise): return unspecified, throw error on failure.
5155 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5157 * regex-posix.c (scm_init_regex_posix): Register the "regex"
5158 feature, to help boot-9.scm decide whether to import the regex
5161 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5163 * eval.c: Include scmconfig.h at the beginning of the file so that
5164 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
5167 * regex-posix.c: #include "_scm.h" before conditionally #including
5168 <regex.h>; the former defines HAVE_REGCOMP.
5170 * regex-posix.c: #include <regex.h> conditionally, so the file is
5171 CPP'able (for dependency scanning) even on systems that don't have
5174 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5176 Add new R4RS-compliant syntax for keywords.
5177 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5178 regardless of the setting of the `keywords' read option.
5179 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5180 can be re-read no matter what the setting of the `keywords' read
5183 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5185 Add support for POSIX regular expressions.
5187 * regex-posix.c, regex-posix.h: New files. (Some code
5188 is taken liberally from rx/rgx.c in the old Guile dist.)
5190 * init.c: Include regex-posix.h.
5191 (scm_boot_guile_1): Call scm_init_regex_posix.
5193 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5194 Add regex-posix.[ch] sources.
5195 * Makefile.in: Regenerated.
5197 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5198 to do this automatically? It didn't for me, bleh.)
5200 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5202 * fports.c (print_pipe_port): New function.
5203 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5204 latter doesn't even take the right arguments.
5206 * Makefile.am: Increment shared lib revision number. I think
5207 sometimes the uninstalled Guile finds the installed shared lib;
5208 Gord says doing this might help. As things turned out, I can't
5209 say whether it does.
5210 * Makefile.in: Regenerated.
5212 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5213 passing it as the closure argument to scm_boot_guile. (Bill
5216 * ports.c (print_void_port, putc_void_port, puts_void_port,
5217 write_void_port, flush_void_port, getc_void_port, close_void_port,
5218 noop0): Use ANSI prototypes instead of K&R declarations, so the
5219 initialization of void_port_ptob gets aggressively type-checked.
5220 Fix arguments of print_void_port and write_void_port. (Bill

5254 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5256 * script.c (scm_find_executable): Use prototype-style definition
5257 here; apparently it's not quite right to have const in a prototype
5258 and then use a K&R declaration. I wonder if stuff like this will
5259 go away if we compile with -Wrequire-prototypes, or whatever that
5260 is... (Bernard URBAN)
5262 * scmhob.h: New text from Bernard URBAN.
5264 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5266 * script.c: Don't #define const on hpux. Configure takes care of
5267 this. (Thanks to Larry Schwimmer.)
5269 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5270 decide whether to #include <unistd.h>, instead of listing a bunch
5271 of systems. Don't #include stdio twice. Removed dyked-out
5272 definition of scm_find_impl_file.
5274 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5276 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5277 library version info to 1:0.

5284 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5285 throw.c: Update copyright years; these files have been worked on
5286 significantly in 1997, but only had copyright years for 1996.
5287 Also, change name of copyright holder on some from Mikael
5288 Djurfeldt to Free Software Foundation; he has signed papers
5289 assigning the changes to the FSF.
5291 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5292 reason not to give the user the option.
5294 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5295 Return #f on end-of-file when scanning table (i.e. when called
5296 with no arguments). Try to catch errors, when we can.
5297 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5299 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5300 external declarations. These are useful.
5302 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5304 * posix.c: don't include <sys/select.h> or define macros for
5305 select, since they were not used in this file.
5307 * filesys.c (scm_select): make the fifth parameter microseconds,
5308 not milliseconds. let the fourth parameter be either a real value
5309 or an integer or #f. The first, second and third arguments can
5310 now be vectors: the type of the corresponding return set will be
5312 (set_element, get_element): new static procedures.
5314 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5316 * strports.c (scm_eval_string): New function.
5317 (scm_eval_0str): Trivially re-implemented in terms of
5319 * strports.h (scm_eval_string): New extern decl.
5321 * net_db.c (h_errno): Add extern decl for this.
5323 * fports.c (local_pclose): New function.
5324 (scm_pipob): Use it in the initializer here.
5327 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5328 Use a meaningful error message when signalling an error. For
5329 this, scm_gethost must check h_errno rather than errno.
5331 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5333 * Makefile.in: Regenerated, using automake-1.1p.
5335 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5337 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5338 not SCM_UNSPECIFIED.
5340 * script.c (scm_compile_shell_switches): don't append (quit) if
5342 (scm_shell): call scm_exit_status and exit on the result of the
5345 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5347 Ensure that shared substrings are handled properly when passed to
5348 a system call or other foreign function. Many thanks to Tim
5350 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5351 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5352 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5353 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

5365 SCM_COERCE_SUBSTR to make sure shared substrings are
5368 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5370 * error.c (scm_error): Add newline to error message.
5372 * init.c (scm_init_standard_ports): Doc fix.
5374 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5376 * dynl-shl.c: Completely replaced with new code from Bernard
5379 * script.c (scm_ice_9_already_loaded): New variable.
5380 (scm_compile_shell_switches): Use it.
5382 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5384 * filesys.c (scm_input_waiting_p): add missing third argument to

5388 calling gmtime in case they share a buffer.
5389 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5392 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5394 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5396 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5398 * Makefile.am (check-local): New target, which causes 'make check'
5399 to run gh_test_c and gh_test_repl, with some trivial input.
5400 * Makefile.in: Rgnrtd.
5402 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5404 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5407 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5409 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5410 sure how this was supposed to work.
5411 (scm_async_click): don't send SCM_TICK_SIGNAL.
5412 (scm_init_async): don't initialize %tick-thunk.
5414 * the following change doesn't affect the Scheme interface:
5415 gc-thunk is called at the end of garbage collection. however it's
5416 no longer implemented by pretending it's a signal.
5418 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5419 system async corresponding to scm_gc_thunk.
5420 * async.h: declare scm_gc_async.
5421 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5422 gc-thunk directly, instead of going through a signal handler.
5423 (scm_gc_async): new variable, points to the GC system-async.
5424 (scm_init_async): save the GC async as scm_gc_async instead
5425 of using system_signal_asyncs.
5426 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5428 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>

5431 Don't screw up if we're interrupted.
5432 * Makefile.in: Regeneradet.
5434 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5436 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5438 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5439 we're not using AM_INIT_GUILE_MODULE any more.
5440 * Makefile.in: Reneregated.

5445 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5446 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5448 Get 'make dist' to work again.
5449 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5450 * Makefile.in: Regenerated, like a surry without a fringe on top.
5452 Changes for reduced Guile distribution: one configure script,
5454 * configure.in, configure: Removed.
5455 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5456 real configure script lives.
5457 * Makefile.in, scmconfig.h.in: Regenerated.
5459 * init.c: #include "script.h", to get prototype for script.c's
5462 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5464 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5465 scm_must_malloc, not raw malloc.
5467 * script.c (scm_compile_shell_switches): Dyke out debugging output
5470 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5472 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5474 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5475 system has them. Hope this is safe. Previously
5476 sys/timeb.h was included if HAVE_FTIME was defined or if
5477 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5478 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5480 * ioext.c (scm_setfileno): add missing third argument to
5481 scm_misc_error call.
5483 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5485 * eq.c (scm_equal_p): Correctly compare strings of different
5486 varieties. (Thanks to Tim Pierce.)
5488 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5490 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5491 #! block comment must occur on a line all by itself.
5493 Move most of the guts of shell command processing into libguile,
5494 so guile.c can be very small (and eventuallly auto-generated. (I
5495 mean, generated mechanically, not self-generated. Hmm.))
5496 * guile.c, script.c, script.h: New source files.
5497 * init.c (scm_boot_guile_1): Call scm_init_script.
5498 * libguile.h: #include "script.h".
5499 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5500 targets, for new executable.
5501 (libguile_la_SOURCES): Mention script.c.
5502 (modinclude_HEADERS): Add script.h.
5503 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5504 not dynamic linking is enabled. This is because we're generating
5505 executables now. Move CY_AC_WITH_THREADS call after those, so the
5506 values of cy_cv_threads_libs captures the libs chosen above.
5507 * Makefile.in, configure, aclocal.m4: Regenerated.
5509 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5510 We don't maintain this interface any more, and it just confuses
5513 * alloca.c: #include <scmconfig.h>, not <config.h>.
5514 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5515 it'll get included in disties.
5517 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5519 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5520 be distributed, because they confuse people.
5521 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5523 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5525 * configure.in: check for presence of gethostent (not present on
5526 OpenBSD by default).
5527 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5528 * configure, scmconfig.h.in: Regenerated.
5530 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5532 * backtrace.c (scm_backtrace): Split message string across
5533 newlines properly. GCC is more tolerant of this than other
5536 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5538 Merge threads directory into libguile.
5539 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5540 threads.h: New source files.
5541 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
5542 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5544 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5545 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5546 coop-threads.c.cygnus, coop-threads.h.cygnus.
5547 * configure.in: If we're using threads, include threads.o in
5549 * _scm.h, libguile.h: threads.h lives in this directory now.
5550 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5551 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5552 currently used, but brought along for information's sake.
5553 * ChangeLog-threads: log from old 'threads' directory.
5554 * Makefile.in, configure: Rebuilt.
5556 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5558 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5561 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5563 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5565 Merge GH interface library into libguile.
5566 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5567 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5568 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5569 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5571 (EXTRA_libguile_la_SOURCES): ... here.
5572 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5573 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5574 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5575 New variables, describing how to build the gh test programs.
5576 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5577 build the test programs, and we probably should have been linking
5578 libguile.la against them all along, to support AIX shared libs.
5579 Add cflags for threads to CFLAGS; add libs for threads to new
5580 variable THREAD_LIBS, used in Makefile.am.
5581 * ChangeLog-gh: log from old `gh' subdirectory.
5582 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5584 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5586 * acconfig.h: Undo change of Apr 9; including the definition of
5587 PACKAGE in the guile headers conflicts with applications' own
5589 * scmconfig.h.in: Regenerated.

5598 when PROC is receiving no arguments.
5600 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5602 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5603 have S_IFSOCK. This is the case under Ultrix.
5605 * posix.c (scm_status_exit_val, scm_status_exit_val,
5606 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5607 Ultrix versions of WIFSTOPPED, etc., which assume that their
5608 arguments are lvalues (hmm).
5610 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5612 * eval.c: Doc fixes.
5614 * throw.c: Doc fixes; rearranged.
5616 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

5620 * acconfig.h: Added entry for PACKAGE.
5621 * scmconfig.h.in: Regenerated.

5624 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5625 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5627 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5629 * Makefile.in: Rebuild.
5631 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5633 * stime.c (scm_mktime): take an optional zone argument.
5634 (scm_localtime): check putenv return value.
5635 (scm_strftime, scm_strptime): moved from posix.c. move #include
5637 stime.h, posix.h: update prototypes.
5638 (bdtime2c, setzone, restorezone): new static procedures.
5639 (scm_mktime, scm_strftime): use them.
5640 (scm_strftime): don't call mktime before strftime. Use
5641 filltime for return value.
5642 (filltime): convert NULL zname to #f.
5643 (scm_strptime): return a count of characters consumed, not
5644 the remaining string.
5646 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5648 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
5649 (scm_mktime): likewise.
5651 Uncomment localtime and mktime.
5653 * configure.in: add AC_STRUCT_TIMEZONE.
5655 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5657 * stime.c (scm_init_stime): don't define ticks/sec.
5658 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5659 return value problem and is still portable.)
5661 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5663 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5664 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5665 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5666 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5667 cpp_err_symbols.c): Corresponding changes.
5668 * Makefile.in: Regenerated.
5670 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5672 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5673 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5674 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5675 * putenv.c: new file, from sh-utils 1.12.
5677 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5678 since allocation isn't for Scheme objects.
5679 (scm_putenv): copy strings before placing in the environment.
5681 * stime.c (scm_current_time): throw an error if time returns -1,
5682 instead of returning #f.
5683 (scm_get_internal_real_time, scm_get_internal_real_time): use
5684 scm_long2num for return value instead of SCM_MAKINUM.
5686 * stime.h: prototypes updated.
5688 * stime.c (scm_time_in_msec): apparently unused, deleted.
5690 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5692 * configure.in: check for gettimeofday.
5694 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5695 which may be more usefully portable than a gettimeofday interface.
5697 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5699 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5701 * Makefile.in: Regenerated.
5703 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5705 * stime.c (filltime): recovered static procedure.
5706 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5709 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5710 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5712 * posix.c (scm_mknod): split the mode argument into type and perms
5713 arguments, like the extra fields returned by stat.
5715 * fports.c (scm_pipob): set the close, free and print procedures.
5716 (scm_close_pipe): new procedure.
5718 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5719 define them in boot-9.scm
5721 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5723 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5724 wan't defined. Don't include fd.h.
5726 * Previously fd.h was regenerated whenever configure was run,
5727 forcing a couple of files to be recompiled.
5729 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5730 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5731 Check for _fileno as well as _file.
5733 * ioext.c: don't fd.h.
5734 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5737 * Change the stratigy for getting information about errno
5738 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5739 generating lists of symbols during the build process, which will
5740 not always work, include comprehensive lists in the distribution.
5741 To help keep the lists up to date, the "check_signals" and
5742 "check_errnos" make targets can be used.
5744 * configure.in: don't check for a command to extract errno codes.
5745 * Makefile.am: update file lists, remove errnos.list and errnos.c
5746 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5747 check_errnos targets.
5748 (CLEANFILES): remove errnos.c and errnos.list, add
5749 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5750 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5751 * errnos.default: deleted.
5752 * cpp_signal.c: new file.
5753 * cpp_errno.c: renamed from errnos_get.c.
5754 * cpp_err_symbols, cpp_sig_symbols: new files.
5755 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5756 * error.c (scm_init_error): #include cpp_err_symbols instead of
5758 * posix.c (scm_init_posix): don't intern signal symbols. #include
5761 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5763 * strop.c (scm_i_index): allow the lower bound to be equal to the
5764 length of the string, so a null string doesn't always give an error.
5766 * posix.h: new prototypes.
5767 * posix.c (scm_status_exit_val, scm_status_term_sig,
5768 scm_status_stop_sig): new functions, as in scsh. They break down
5769 process status values as returned by waitpid.
5771 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5773 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5774 configure doesn't know about it.
5776 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5778 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5780 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5781 which defines C variables with global linkage.
5783 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5785 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5788 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5790 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5791 has time to check why this doesn't work well with continuations.
5793 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5795 * Fix shell syntax error; some shells won't tolerate
5796 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5798 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5800 * posix.c (scm_uname): throw an error if uname fails instead
5803 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5805 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5808 * async.c (scm_ints_disabled): definition moved from error.c.

5812 * acconfig.h: Removed PACKAGE.
5814 * scmconfig.h.in: Regenerated.
5816 * snarf.h: g++ says it's non-portable not to specify the first
5817 argument in a varargs declaration. I introduced the first
5818 argument by using preprocessor conditionals.
5820 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5822 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5823 (scm_freopen): use RO string macros for filename and modes.
5824 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.

5837 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5840 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,

5842 support for byte vectors.
5844 * print.c (scm_iprin1): Limit number of vector elements printed
5845 according to pstate->length.
5847 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>

5852 * error.h: prototype for scm_error_scm.
5854 * error.c (scm_error_scm): new procedure, reimplements scm-error
5855 in C and uses scm_error.
5857 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5859 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5860 pointer to the Scheme variable read-hash-procedures and intern it
5861 in scm_init_read. Modify scm_read_hash_extend and
5862 scm_get_hash_procedure to use the pointer.
5864 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5866 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5867 (SCM_KEYWORD_STYLE): defined.
5869 * read.c (scm_read_opts): add a keywords option. This isn't a
5870 boolean option, in case someone wants to add support for DSSSL
5872 Setup scm_keyword_prefix symbol.
5873 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5875 I've left keyword support disabled by default, since it doesn't
5876 seem to break the module system and it gives R4RS standard behaviour.
5877 It can be reactivated with (read-set! keywords 'prefix).
5879 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5881 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5882 before constructing arbiter.
5884 * eval.c (scm_m_define): Bugfix: Check that the object is a
5885 closure before setting the procedure property!
5887 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5889 * ports.c: Removed `ungetc-char-ready?'.

5893 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5894 (idea from Mikael: make it a pair so scm_permanent object only
5896 (scm_read_hash_extend): don't call scm_permanent_object.
5897 (ideas from Mikael): if chr is already in the list, replace its
5898 procedure instead of appending it again. If proc is #f, remove
5900 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5902 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5904 * gdbint.c (gdb_read): update scm_lreadr usage.

5918 for extended # processing.
5919 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5920 scm_read_token): remove case_i, sharp arguments. Change callers.

5924 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5925 (SCM_CASE_INSENSITIVE_P): define.
5927 * read.c: add case-insensitive option to scm_read_opts.
5928 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5929 to determine whether to convert symbol case.
5930 (default_case_i): definition removed.
5931 * read.c (scm_read_token): if case_i, downcase ic before doing
5934 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5936 * configure.in: Added configuration option `guile-debug'.
5937 Configure with --enable-guile-debug if you want a bunch of extra
5938 functions used for debugging when developing Guile.
5940 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5942 * procs.c (make-cclo): New undocumented debugging procedure: Make
5943 compiled closure with internal procedure PROC and length LENGTH.
5944 Only compiled if GUILE_DEBUG is defined.
5946 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5948 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5950 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5952 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5953 with 3 or more args internally to the evaluator.
5955 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5957 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5958 with 3 or more args internally to the evaluator. This is mainly
5959 because we don't want to pass entry and exit points of the
5960 debug support twice, but it also seems to increase the speed of
5961 the evaluator for such calls (e. g. (+ 1 2 3)).
5963 * backtrace.c (scm_display_application): New procedure:
5964 display-application; Set fancy printing parameters individually
5965 for different types of display (backtrace, error, application).
5966 (These should of course be customizable!)
5968 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5969 clear the CHECK-flags.
5971 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5973 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5975 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5977 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5978 from pairs with a GLOC in the car.
5980 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5981 otherwise `symbol-hash' will behave badly.
5982 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5983 we get segmentation fault!
5985 * symbols.c: Added #include "weaks.h". New functions:
5986 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5987 moved to an extraneous library when we split libguile.)
5989 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5991 * filesys.c (scm_stat): stat now takes fport arguments too as
5992 documented in the manual.
5994 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5996 * debug.c (scm_single_step): Bugfix: Call continuation with
5997 scm_call_continuation instead of throwing to it.
5999 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
6001 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
6002 argument wasn't declared to be optional.
6004 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6006 * stime.c (scm_init_stime): Add feature "current-time".
6008 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6010 * throw.h: prototype for scm_exit_status.
6011 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
6012 args to derive an exit status. Allows (quit) to work from a
6014 (scm_exit_status): new function.
6017 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6019 * eval.c (scm_deval): Removed some old code.
6020 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
6022 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
6025 * symbols.c (msymbolize): Bugfix: Must initialize property list to
6028 * procs.c: Introduce the existent C function scm_thunk_p at the
6029 Scheme level as well.
6031 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6033 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
6034 used from C to easily lookup the value of a symbol in the current
6037 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6039 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
6040 scm_init_unif in this file. This will also fix a previous problem
6043 * configure.in: Added AM_MAINTAINER_MODE
6045 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6047 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
6050 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6052 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
6053 source files that are not always included in libguile but should
6054 have their dependencies calculated by automake. This variable is
6055 recognized by automake, no further magic is needed.
6056 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
6057 to deal exclusively with *.lo files, as it seems. The *.o files
6058 are built automatically when the corresponding *.lo file gets
6061 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
6063 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
6066 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
6068 * unif.c (scm_array_set_x): minor change to argument error checking.
6070 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
6072 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
6073 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
6074 They should only be included in the library at configure.in's
6076 (libguile_la_LDADD): Include the appropriate .lo files here.
6077 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
6078 so we know when to build them (and their .lo bretheren).
6079 * configure.in (LIBLOBJS): New substituted variable. We let
6080 configure decide which .o files to include in LIBOBJS, and then
6081 put the corresponding list of .lo files in LIBLOBJS. The latter
6082 is what we pass to libtool.
6083 * Makefile.in, configure: regenerated.
6085 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
6087 * symbols.c (scm_sysintern0): New function. Contains the core of
6088 old scm_sysintern but doesn't take a second value argument.
6089 (scm_sysintern): Now uses scm_sysintern0.
6090 (scm_sysintern_no_module_lookup): Renamed to
6091 scm_sysintern0_no_module_lookup and doesn't take a second value
6092 argument any longer.
6094 * symbols.h (scm_sysintern0: Added declaration.
6096 * options.c (scm_init_opts): Use scm_sysintern0 instead of
6097 scm_sysintern when interning option keys. Otherwise we risk
6098 destroying the values of already interned variables.
6100 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
6101 scheme-level boolean (use SCM_NFALSEP).
6103 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
6105 (scm_backtrace): New function. (C version of old function from
6106 boot-9.scm) Motivation: Make it possible to display backtraces
6107 without depending on boot-9.scm. (I'm uncertain if this
6108 motivation is good enough...)
6110 * root.h (scm_root_state): Add member the_last_stack_var.
6111 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
6113 * root.c (mark_root): Mark scm_the_last_stack_var.
6115 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
6118 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
6120 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
6121 1. mark_lazy_catch didn't mark the smob.
6122 2. Both functions above have standard variants:
6123 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
6124 free_lazy_catch --> scm_free0.
6126 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
6128 * throw.c (scm_internal_lazy_catch): New function.
6129 (scm_lazy_catch): Rewritten to use it.
6130 (scm_ithrow): Handle the new lazy catch representation.
6131 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
6132 that doesn't have a jmpbuf is a lazy catch clause.
6133 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
6134 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
6135 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
6137 (scm_init_throw): Register the new lazy-catch smob type.
6138 * throw.h (scm_internal_lazy_catch): decl for new function.
6140 * throw.c (scm_internal_catch): Doc fixes.
6142 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
6143 configure.in. Including this might cause problems if applications
6144 that link against libguile include their own copies of alloca, but
6145 if they're using autoconf, they should be adding libguile to LIBS
6146 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
6147 the copy in libguile, and things will be okay. (I think.)
6149 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6151 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
6153 strop.h: move prototypes too.
6155 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6157 * posix.c (scm_init_posix): don't intern EINTR since it's now done
6160 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
6161 etc. I deleted them from filesys.c long ago, but didn't
6162 notice they were here too (although ineffective since
6163 sys/stat.h wasn't included).
6165 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
6167 * eval.c: Don't define alloca in GCC case. gcc will automatically
6168 use __builtin_alloca if appropriate.
6170 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6172 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6173 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6174 that values of automatic variables are preserved. See comments
6175 for safe_setjmp for details.
6177 Change from Thomas Morgan:
6178 * variable.c: Include eq.h.
6179 (var_equal): New function.
6180 (variable_smob): Use var_equal as the discriminator for variables.
6182 * throw.c (s_throw): Remove extraneous declaration.
6184 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6185 * eval.c: Add necessary CPP cruft to support that.
6186 * configure, Makefile.in, scmconfig.h.in: regenerated.
6188 Change from Thomas Morgan:
6189 * procprop.c (scm_procedure_properties): Convert the Scheme
6190 boolean returned by scm_procedure_p into a C boolean before using
6191 it as a condition for SCM_ASSERT.
6192 (scm_procedure_property): Likewise.
6194 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6195 indications of Unixness.
6198 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6200 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6202 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6204 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6205 "unknown # object" error messages.
6207 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6208 (scm_i_index) and declare it static. Add a 'direction' argument
6209 to indicate what way the search should go.
6210 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6212 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6213 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6215 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6217 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6219 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6220 to avoid clash with various scsh forks.
6222 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6224 The following two changes (ramap.c, throw.c) are motivated by the
6225 apparent unportability of forward declarations of static arrays of
6226 the form `static foo bar[];'.
6228 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6229 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6231 * throw.c (scm_throw): Moved above scm_ithrow.
6233 * options.h: Removed the extern declarations of scm_yes_sym and
6234 scm_no_sym since these are static.
6236 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6238 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6240 * Makefile.am: remove AWK=@AWK@.
6241 Add a rule for generating errnos.list.
6242 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6244 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6245 don't extract errnos, just set a variable (avoids the
6246 need to recompile error.c just because configure is run.)
6248 * unif.h: update prototypes.
6249 * unif.c (scm_uniform_array_read,write): change the offset and
6250 length arguments to start and end, for consistency.
6252 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6254 * ioext.h: update prototypes.
6255 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6256 scm_read_line_x, it's a more general procedure using an
6257 interface from scsh. read-line and read-line! are now defined
6259 Note that the new read-line trims the terminator
6260 by default, previously it was appended to the returned string. An
6261 optional argument specifies how to process the terminator (scsh
6262 compatible). For the old behaviour: (read-line port 'concat).
6263 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6264 returns a pair, but is converted to multiple values if the scsh
6267 socket.h: update prototypes.
6268 * socket.c (scm_recvfrom): for consistency with other procedures,
6269 take start and end as separate optional arguments.
6270 (scm_recv, scm_recvfrom): don't allow the second argument
6271 to be a size, only a buffer. Change the scheme names to
6272 recv! and recvfrom!. Don't return the buffer.
6274 * ioext.h, posix.h: move prototypes too.
6275 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6276 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6277 "read.h" and "unif.h".
6278 * ioext.c: include "chars.h"
6280 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6282 * dynl.c: The dynamic linking and module registration functions
6283 are now defined even when dynamic linking is not available for the
6284 host system. Some of their functionality can be done without
6285 dynamic linking; when it's really needed, they throw errors.
6287 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6289 * configure.in: Only define DYNAMIC_LINKING when one of the system
6290 dependent functions is detected.
6291 * dynl.c (scm_dynamic_func): New function to get the address of a
6292 function in a dynamic object.
6293 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6294 produced by scm_dynamic_func as the thing to call.
6296 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6298 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6299 (scm_register_module_xxx, scm_registered_modules,
6300 scm_clear_registered_modules): New functions.
6302 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6304 * symbols.c (scm_sysintern): Renamed to
6305 scm_sysintern_no_module_lookup.
6306 (scm_sysintern): New function to take the place of the old
6307 scm_sysintern. It uses the current toplevel lookup closure to give
6308 the symbol its value. This is a temporary hack to put packages
6309 like gtcltk into their own module.
6310 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6311 us whether `scm_top_level_lookup_closure_var' has been initialized
6313 * eval.c (scm_init_eval): Set it.
6315 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6317 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6318 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6320 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6322 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6323 scm_sys_dup): deleted: FD capability will be added to other
6325 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6326 scm_fd_free, fd_smob, scm_intern_fd.
6327 (scm_open): renamed from scm_sys_open. Return a port instead of
6328 an FD object. Make the mode argument optional.
6329 (scm_sys_create): deleted, it's just a special case of open.
6330 (scm_init_filesys): move interning of constants O_CREAT etc.,
6331 here (were previously using SCM_CONST_LONG macro).
6332 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6334 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6335 include "fports.h" and <stdio.h>
6336 (scm_stat, scm_select): don't support FD objects.
6338 * error.h: adjust scm_syserror_msg prototype.
6339 * error.c (scm_syserror_msg): take an extra argument for errno.
6340 Using the global value didn't always work, since it could be
6341 reset by procedure calls in the message or args arguments.
6343 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6344 I don't understand why the check was there (and what about the
6347 * strop.c (scm_string_copy): allow shared substrings to be copied.
6349 * unif.h: corresponding change to prototypes.
6350 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6351 recognize two new optional arguments: offset and length. Allow
6352 the port argument to be an integer (file descriptor, for scsh).
6353 Include <unistd.h> for "read" prototype.
6355 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6357 * socket.c: don't include filesys.h.
6359 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6361 * Makefile.am: add AWK=@AWK@ (?)
6363 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6365 Add a rule to generate errnos.c from errnos.
6366 * error.c (scm_init_error): include errnos.c.
6367 * errnos_cnvt.awk: new file, converts the list of errno codes to
6369 * errnos_get.c: new file.
6370 * errnos.default: new file, contains errnos to try if they can't
6371 be extracted from errno.h.
6372 * configure.in: if using GCC, try and extract errno codes from
6376 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6378 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6379 * Makefile.am: Made libguile into a libtool library.
6380 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6381 Set libtool_libs to indicate that libguile is a libtool library.
6382 See guile/ChangeLog for details.
6383 * .cvsignore: ignore "*.lo", the libtool library objects.
6385 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6387 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6388 use htons in getservbyport argument.
6390 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6392 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6393 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6396 * objprop.c (scm_object_property): No need to take the CDR of the
6397 value returned by scm_object_properties, since Aug 20 change.
6399 * configure.in: When checking for struct linger, #include
6400 <sys/types.h> as well as <sys/socket.h>. I've never known
6401 <sys/types.h> to cause any portability problems, and Solaris's
6402 <sys/socket.h> needs it.
6403 * configure: Rebuilt.
6405 I think the Sun compiler has chosen a perverse way to interpret
6406 ANSI declarations combined with K&R definitions. We'll
6407 appease it a little bit. But when it invades France, we fight.
6408 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6409 * print.h (scm_iprlist): Here too.
6410 * numbers.c (scm_divbigdig): Change definition to match
6411 declaration in numbers.h.
6412 * unif.c (scm_makflo): Change definition to match declaration in
6415 * init.c (scm_boot_guile): Don't return the value of
6416 scm_boot_guile_1. This function doesn't return a value;
6417 scm_boot_guile_1 doesn't return a value (or return at all).
6419 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6422 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6423 compile. I have a feeling this function is a bad idea anyway ---
6424 one should always test for features, not systems.
6426 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6427 semicolons. Only pure luck kept this from being noticed earlier.
6429 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6431 * socket.c (scm_recvfrom): Added missing semicolon.
6433 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6435 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6436 the buffer and start and end positions for scsh networking
6439 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6441 * configure.in: Revert previous change to this file; the problem
6442 is due to transient automake weirdness.
6443 * configure: Rebuilt.
6445 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6446 PLUGIN/guile.libs. configure generates the latter from the former.
6447 * Makefile.in: Rebuilt.
6449 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6450 need this if we install scripts, like guile-snarf.
6451 * configure: Rebuilt.
6453 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6455 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6457 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6459 * socket.c (scm_addr_vector): fix faulty scm_listify.
6461 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6463 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6464 style block comment is no longer considered an error.
6466 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6468 * PLUGIN/guile.libs.in: New file.
6469 * PLUGIN/guile.libs: Removed from repository.
6470 * configure.in: Create PLUGIN/guile.libs from
6471 PLUGIN/guile.libs.in. This is for including additonal libraries
6472 needed for dynamic linking.
6473 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6474 instead of PLUGIN/guile.libs.
6476 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6478 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6480 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6481 occurrences of the given element from the list, not just the
6482 first. This is how the Emacs Lisp functions behave, how the
6483 analogous Common Lisp functions behave, and (I believe) how the
6484 older Maclisp functions worked. I realize that this change may
6485 break code, but it seemed better to break it before the Guile
6488 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6489 Their prototypes were already present in gc.h, but they weren't
6491 (scm_init_storage): Initialize scm_protects.
6492 * root.c (scm_protects): New element of scm_sys_protects.
6494 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6496 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6498 * libguile.h: Added #include "libguile/net_db.h".
6500 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6501 30 change. That file is only meant for communication between the
6502 configuration process and load.c. If code linked against libguile
6503 wants to get at the paths mentioned in libpath.h, it can call
6504 functions declared in load.h.
6506 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6508 * libguile.h: Removed #include "libguile/fdsocket.h"
6510 * net_db.c: Added #include <sys/socket.h>.
6512 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6514 * filesys.c (scm_input_waiting_p): use select in preference to
6515 FIONREAD, since the latter doesn't detect EOF.
6516 Throw error if neither select nor FIONREAD available.
6518 * socket.c (scm_connect): take a port, not a fd object.
6519 (scm_fill_sockaddr): throw an error if fam is not recognised.
6520 (scm_bind): use scm_fill_sockaddr.
6521 (scm_listen): take a port, not a fd object.
6522 (scm_accept): take and return a port. return #f in the car if
6523 address can't be got
6524 (scm_sock_fd_to_port): new procedure.
6525 (scm_socket): use scm_sock_fd_to_port.
6526 (scm_addr_vector): throw error if unrecognised address type.
6527 take an extra argument with the calling procedure name.
6528 (scm_getsockname): take a port. return #f if address can't be got.
6529 (scm_getpeername): take a port. return #f if address can't be got.
6530 (scm_recvfrom): take a port. return #f for address component if can't
6532 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6533 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6535 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6537 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6538 use separate data pointers, to allow them to be designed
6539 independently and reused.
6540 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6541 Renamed from catch_body, catch_handler, and uncaught_throw; made
6543 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6545 (scm_catch): Use the above.
6546 (scm_throw): Don't bother printing a message for an uncaught
6547 throw; we establish a default handler in init.
6548 * throw.h (scm_internal_catch): Prototype updated.
6549 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6551 (struct scm_body_thunk_data): New structure, used as data
6552 argument to scm_body_thunk.
6553 * init.c (struct main_func_closure): New structure, packaging up
6554 the data to pass to the user's main function.
6555 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6556 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6557 scm_internal_catch to establish a catch-all handler, using
6558 scm_handle_by_message. This replaces the special-case code in
6560 (invoke_main_func): Body function for scm_internal_catch; invoke
6561 the user's main function, using the main_func_closure pointer to
6562 decide what to pass it.
6563 * root.c (struct cwdr_body_data): Remove handler_proc member.
6564 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6565 (cwdr_handler): Removed.
6567 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6569 * socket.h (SCM_P): update bind prototype.
6570 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6571 include "feature.h".
6572 (scm_socket): return a port, not a file descriptor object.
6573 include "fports.h" and <unistd.h>
6574 (scm_bind): take a port, not a file descriptor object.
6575 take an extra argument for address args.
6577 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6578 INADDR_NONE, INADDR_LOOPBACK.
6580 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6582 * init.c: include net_db.h and not fdsocket.h.
6583 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6585 * Makefile.am: corresponding changes.
6586 * socket.h: renamed from fdsocket.h, fix names.
6587 * net_db.h: renamed from socket.h, fix names.
6588 * socket.c: renamed from fdsocket.c.
6589 remove _sys from procedure names.
6590 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6591 add "socket" to features list.
6592 * net_db.c: renamed from socket.c.
6593 remove _sys from procedure names.
6594 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6595 add "net-db" to features list.
6596 include "net_db.h". don't include <sys/socket.h> or
6599 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6601 * tags.h (scm_tags): Removed comma at end of last enumerator.
6603 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6605 Don't use GCC extensions to allocate space for debugging frames.
6606 (Here he goes again! Why do we put up with this?!)
6607 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6608 an scm_debug_info structure, not an in-line array of them. Add
6609 'info' member, to say how many vect elements we've used, for eval
6611 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6612 a new variable debug_info_end to mark the end of vect, instead of
6613 the address of the 'info' pointer itself.
6614 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6615 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6616 (SCM_APPLY): Explicitly allocate space for debug.vect.
6617 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6618 * stacks.c: Adjusted for new debug frame structure.
6619 (RELOC_INFO, RELOC_FRAME): New macros.
6620 (stack_depth, read_frames): Use them, and new scm_debug_frame
6621 element 'info', instead of magically knowing that eval frames have
6622 an info pointer sitting after vect.
6623 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6625 (scm_init_stacks): Formatting tweaks.
6627 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6629 Give GCC more control flow information, so it can be sure that
6630 variables aren't used uninitialized.
6631 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6632 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6633 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6634 scm_misc_error): Tell GCC that these functions never return.
6635 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6636 out the field type, call abort if SCM_ASSERT returns, to placate
6638 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6639 scm_wta ever returns. We can't handle this case anyway, and this
6640 gives the optimizer more information.
6641 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6642 scm_wta ever returns.
6644 In some cases, the code is fine, but GCC isn't smart enough to
6645 figure that out; this usually happens when one variable is only
6646 initialized and used when a particular condition holds true, and
6647 we know that condition will never change within a given invocation
6648 of the function. In this case, we simply initialize the variables
6649 to placate the compiler, hopefully to a value which will cause a
6650 crash if it is ever actually used.
6651 * print.c (scm_iprin1): Initialize mw_pos.
6652 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6653 * throw.c (scm_ithrow): Initialize dynpair.
6654 * unif.c (scm_uniform_vector_ref): Initialize cra.
6655 * struct.c (init_struct): Initialize prot.
6656 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6658 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6659 if EXPR contains no expressions.
6661 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6663 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6664 cause an infinite loop (???). So much for the algebraic
6665 equivalency of variable-sized arrays and alloca...
6667 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6669 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6670 a SCM boolean, not a C boolean.
6672 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6674 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6675 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6676 rules for raising scm_mtrigger. Previously, unfortunate but not
6677 unlikely circumstances could result in almost constant invokation
6678 of the gc. Now, this situations should be less likely, but they
6679 are not prevented completely.
6681 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6683 * numbers.c (scm_fuck): Procedure removed; looks like old test
6685 * numbers.h: Prototype removed.
6687 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6689 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6690 array to a pointer, to match my Nov 21 change in eval.c.
6692 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6694 * libguile.h: Added #include "libguile/backtrace.h", #include
6695 "libguile/stacks.h".
6697 * strings.c (scm_string scm_make_string scm_string_ref
6698 scm_string_set_x scm_string_equal_p scm_string_append):
6699 Bugfix according to scm patch from Aubrey Jaffer:
6700 Corrected long-standing
6701 (not (eqv? (integer->char 128)
6702 (string-ref (make-string 1 (integer->char 128)) 0)))
6703 bug found by John Kozak <jk@noontide.demon.co.uk>.
6705 * strports.c, strports.h: Make scm_eval_0str return the value of
6706 the last expression evaluated (previously, it returned void).
6708 * strports.c, strports.h: New function: scm_read_0str. Does what
6711 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6713 * simpos.c (scm_getenv): return #f if string can't be found in the
6714 environment instead of throwing an exception, for compatibility
6715 with numerous other systems.
6717 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6719 * Makefile.am (.c.x): Use guile-snarf.
6720 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6722 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6724 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6726 * backtrace.c (scm_display_error_message): Made non-static, and
6727 renamed from display_error_message.
6728 * backtrace.h (scm_display_error_message): Added extern decl.
6729 * throw.c (uncaught_throw): Use it to display the error message.
6731 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6733 * inet_aton.c: Use #if 0, not #ifdef 0.
6735 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6737 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6738 to convert the returned value.
6739 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6740 the offset argument.
6742 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6744 Add new interface to catch/throw, usable from C as well as
6746 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6747 (scm_internal_catch): New function, replaces...
6748 (scm_catch_apply): Deleted.
6749 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6750 mechanism which is a bit more code, but can be used nicely from C
6751 and implement the Scheme semantics as well.
6752 (scm_internal_catch): This is the replacement; it's named after
6753 the analogous function in Emacs.
6754 (scm_catch): Reimplemented in terms of the above.
6755 (struct catch_body_data, catch_body, catch_handler): New
6756 functions, used by scm_catch.
6757 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6758 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6759 support for new cwdr.
6761 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6764 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6766 * acconfig.h: Added DYNAMIC_LINKING symbol.
6767 * configure.in: Add option and checks for dynamic linking.
6768 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6769 dynl.h: New files for dynamic linking support.
6770 * Makefile.am (libguile_a_SOURCES):
6772 (modinclude_HEADERS): Added "dynl.h".
6773 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6775 * init.c (scm_boot_guile_1): Call
6776 scm_init_dynamic_linking to initialize dynamic linking support.
6778 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6780 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6781 (as we Schemers say). It needs to be global, so that I can tweak
6782 it for the proper operation of unexec.
6783 (scm_boot_guile_1_live): New variable, see above.
6785 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6787 * guile-snarf.sh: Removed.
6788 * PLUGIN/guile.libs: Added dependency for -lm.
6789 * acinclude.m4: Renamed from aclocal.m4.
6790 * PLUGIN/greet: Removed.
6791 * Makefile.am, aclocal.m4: New files.
6792 * configure.in: Updated for Automake.
6794 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6796 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6797 and not top_level_lookup_thunk_var.
6799 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6801 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6803 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6805 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6806 Scheme function, instead of syntax. Single argument is now a
6809 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6811 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6812 scm_ra_divide): Properly terminate statements passed as arguments
6813 to IVDEP macros. (Thanks to Bernard Urban.)
6815 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6816 with non-constant sizes. (Thanks to Bernard Urban.)
6818 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6820 It's an "eval closure", not an "eval thunk." A thunk is a
6821 function of no arguments.
6822 * root.h (struct scm_root_state): Renamed
6823 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6824 (scm_top_level_lookup_closure_var): Renamed from
6825 scm_top_level_lookup_thunk_var.
6826 * root.c (mark_root): Uses changed.
6827 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6828 * init.c (scm_start_stack): Uses changed.
6829 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6830 Change scheme-visible name to *top-level-lookup-closure* from
6831 *top-level-lookup-thunk*.
6833 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6835 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6836 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6838 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6840 * gc.c (struct scm_heap_seg_data): Doc fixes.
6842 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6843 sweeping. Then, prepend each segment's free cells to its
6844 freelist, rather than wiping out the old value. (Thanks to Marius
6847 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6848 scm_check_freelist, scm_debug_newcell): New functions and
6849 variables, for debugging freelist problems.
6850 * pairs.h (SCM_NEWCELL): New debugging version added.
6851 * gc.h (scm_debug_newcell): Added extern declaration, used by
6852 debugging version of SCM_NEWCELL.
6854 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6856 On some systems <libc.h> conflicts with <unistd.h>, and should not
6857 be #included at all.
6858 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6859 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6860 * configure.in: Call it.
6861 * posix.c, filesys.c: Use its results to decide whether or not to
6863 * configure, scmconfig.h.in: Rebuilt with autoconf and
6866 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6868 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6869 pointer to the stdio stream before calling scm_setbuf0, so the
6870 latter will be able to retrieve it. I'm surprised this didn't
6871 segfault earlier. (Thanks to Christopher Lee.)
6873 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6875 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6878 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6880 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6881 number of stack narrowing specifier pairs. The first specifier in
6882 a pair controls inner border, the second the outer border. A
6883 number means cut that number of frames, a procedure object means
6884 cut until that object is found in operator position in a frame.
6886 * root.c (cwdr): Bugfix.
6888 * read.c: Recording of positions disabled by default.
6890 * procs.c (scm_closure_p): New function.
6892 * posix.c (scm_tmpnam): New function.
6894 * load.c: Added #include "throw.h".
6895 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6898 * load.c, load.h (scm_read_and_eval_x): New function.
6900 * eval.c: Renamed debug option "deval" to "debug".
6902 (scm_eval_x): `eval!' is no longer accessible from the scheme
6903 level. Motivation: We can't allow operations which introduce
6904 glocs into the scheme level. Guile's type system can't handle
6905 these as data. Use `eval' or `read-and-eval!' as replacement.
6907 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6908 SCM_CONSP since this is a macro!; Set vframe.prev to
6909 scm_last_debug_frame instead of 0. In this way we can look
6910 "above" the virtual start stack frame if we wish.
6911 (scm_debug_hang): New function: Useful for debugging Guile in
6912 certain tricky situations. Will probably be removed later...
6914 * debug.h: Changed semantics of debug option "backtrace". This
6915 option now only indicates whether we want automatic backtrace at
6918 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6920 * ports.c: #include "filesys.h"
6921 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6923 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6924 Motivation: This is system specific code which is related to file
6925 I/O. It also may use select. Added code by Gary Houston to
6926 detect presence of character in stdio buffers.
6928 * libguile.h: #include "libguile/libpath.h"
6930 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6931 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6932 SCM_SITE_DIR; Install libpath.h among the other include files.
6934 * load.c, load.h (scm_sys_package_data_dir): New function.
6936 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6938 * stacks.h: Bugfix: Don't use tail-array length field as stack
6939 length field! This screwed GC.
6941 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6943 * _scm.h: Added #ifndef around definition of macros min and max.
6945 * __scm.h: Added hooks for threads to plugin to in ints protection
6946 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6947 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6948 the main code in these macros duplicated and spread over multiple
6949 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6950 SCM_THREAD_SWITCHING_CODE.
6952 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6954 * snarf.h: New file.
6955 * guile-snarf.sh: New file.
6956 * Makefile.in (inner_h_files): Added snarf.h
6957 (ancillary, install, uninstall, distclean): Added actions for
6959 (.c.x): Use guile-snarf.
6960 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6961 (gen_c_files): Note that these depend on guile-snarf.
6962 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6963 now in "snarf.h". Added #include "snarf.h" to get them.
6964 * libguile.h: Added #include "snarf.h".
6965 (Patches applied and tweaked by Jim Blandy.)
6967 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6969 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6970 standards suggest against providing prototypes for system
6971 functions. Thanks to Greg Troxel.
6973 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6975 * strports.c (scm_eval_0str): New function.
6976 #include "read.h", to get prototype for scm_read.
6977 * Makefile.in (strports.o): Update dependencies.
6978 * strports.h: New prototype.
6980 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6981 scheme name from "int?" to "integer?". It seems to do the job.
6982 * numbers.h: Rename prototype too.
6983 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6986 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6987 scm_num_eq_p): Rename these according to R4RS conventions: call
6988 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6989 to making libguile R4RS compliant without ice-9...
6991 * load.c (scm_sys_search_load_path): Search for files under all
6992 extensions listed in the %load-extensions variable. If FILENAME
6993 is absolute, return it unchanged, without searching the load path.
6994 (scm_loc_load_extensions): New variable, pointing to
6995 %load-extensions' value cell.
6996 (scm_init_load): Initialize it, and the value it points to.
6997 (scm_primitive_load_path): Improve error reporting.
6999 * load.c (scm_loc_load_hook): New variable, pointing to value cell
7000 of new Scheme variable %load-hook.
7001 (scm_primitive_load): Apply %load-hook to filename.
7003 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
7005 * configure.in: add tests for figuring out whether buffered data
7006 is available in a FILE structure, which is needed by char-ready.
7008 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
7011 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
7012 exceptions using misc_error instead of syserror. It seems a bit
7013 odd to throw an exception if a string can't be found in the
7014 environment, but it's consistent with open-file, stat etc.
7015 (simpos.h): remove sys_ from getenv.
7017 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
7018 occurs, throw an error instead of returning errno. Return value
7020 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
7022 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
7024 * filesys.c (scm_stat2scm): derive file type and permissions from
7025 the stat mode and append them to the returned vector.
7026 There isn't much overhead in doing this and it avoids the need to
7027 work with S_IRUSR et al. in Scheme.
7028 Define symbols scm_sym_regular etc.
7029 (scm_init_filesys): don't intern S_IRUSR etc.
7031 * load.c: change s_try_load and s_try_load_path to s_primitive_load
7032 and s_primitive_load_path.
7034 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
7036 * error.h: don't declare error symbols. prototype for scm_misc_error.
7038 * stackchk.c (scm_stack_overflow_key): defined here instead of in
7041 * error.c: use SCM_SYMBOL to set up error keys.
7042 scm_misc_error: new procedure.
7044 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7046 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
7047 between `#!' and `!#' is ignored.
7048 (skip_scsh_block_comment): New function.
7050 * feature.c (scm_set_program_arguments): New argument, FIRST.
7051 * feature.h: Update prototype.
7052 * init.c (scm_boot_guile_1): Pass new argument to
7053 scm_set_program_arguments.
7055 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7057 * init.c (scm_start_stack): Don't initialize scm_progargs here.
7058 (scm_boot_guile): Call scm_set_program_arguments here, later than
7059 the old initialization.
7061 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
7062 initialization procedure.
7063 - Delete in, out, err arguments; there are other perfectly good
7064 ways to override these when desired.
7065 - Delete result argument; this function shouldn't ever return.
7066 - Rename init_func argument to main_func, for less confusion.
7067 - Delete boot_cmd argument; main_func is more general.
7068 -Add 'closure' argument, to help people pass data to main_func
7069 without resorting to global variables.
7070 - Abort if reentered; don't bother returning an error code.
7071 - Call scm_init_standard_ports to set up the default/current
7072 standard ports; no need to pass them to scm_start_stack.
7073 - Remove code to evaluate the boot_cmd, and start the repl; let
7074 the user do something like that in main_func if they want.
7075 - Remove code to package up a return value; main_func can do any
7077 - Call exit (0), instead of returning.
7078 (scm_start_stack): Don't initialize the I/O ports here; that's
7079 weird. Delete in, out, err arguments. Move guts to
7080 scm_init_standard_ports, scm_stdio_to_port.
7081 (scm_init_standard_ports): New function, to set up current and
7082 default standard ports.
7083 (scm_start_stack, scm_restart_stack): Make these static.
7084 * init.h (scm_boot_guile): Adjust declaration.
7085 (scm_start_stack, scm_restart_stack): Remove externally
7086 visible declarations for these.
7087 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
7089 * fports.c (scm_stdio_to_port): New function. Its guts used to be
7090 written out several times in scm_start_stack.
7091 * fports.h: New declaration for the above.
7093 * feature.c (scm_set_program_arguments): New function.
7094 * feature.h: New declaration for the above.
7096 * ports.c: Formatting tweak.
7098 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
7100 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
7101 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
7102 for obtaining the address of a car or cdr field. Motivation:
7103 &SCM_CXR make assumptions about the internal structure of the
7106 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
7107 Motivation: see SCM_CXRLOC.
7109 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
7110 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
7111 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
7112 Motivation: Safer use. Some other macros are defined in terms of
7113 these operations. If these are defined using the SCM_SETCXR
7114 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
7115 to inefficiency and an <e1> with side-effects could potentially
7116 break. Also, these particular operations are heavily utilized in
7117 the garbage collector. In unoptimized code there will be a
7120 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
7121 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
7122 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
7123 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
7124 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
7125 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
7126 vports.c: Cleaned up use of pairs: Don't make any special
7127 assumptions about the internal structure of selectors and
7128 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
7129 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
7130 (Among other things, this change makes it easier to build Guile
7131 with certain compilers which have problems with casted lvalues.)
7133 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7135 * stacks.c: Improve selection of relevant stack frames when making
7136 a stack object. Introduce one level of indirection in the stack
7137 object to make it possible to "narrow" to a certain region of the
7138 stack. This facilitates making use of more clever algorithms (not
7139 implemented) for selecting relevant frames and gives a cleaner
7140 design since selection of frames can be done independently of
7141 extraction of frames from the real stack.
7142 (scm_stack_id): Also take #t as argument which means look at
7145 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
7146 Turn n_tail into an integer directly representing current number
7147 of frames in stack. Add field tail.
7149 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
7151 * debug.c (scm_make_memoized): Made it available at scheme level.
7152 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
7153 SCM_NIMP before applying heavier predicates in argument checking.
7154 (scm_local_eval): Also take memoized object as argument.
7156 * backtrace.c (scm_display_error): Just a safety measure: Stacks
7157 aren't created with zero length, but should such a strange
7158 creature suddenly turn up...
7160 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
7162 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
7163 `del', for the sake of C++ compilers. (Patch applied by JimB.)
7165 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
7167 * variable.c (scm_make_variable): Make the name hint optional, as
7169 (anonymous_variable_sym): Renamed from variable_sym. All uses
7172 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7173 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7174 of scm_primitive_load_path was also changed to
7175 "primitive-load-path", from "%try-load-path". Callers changed.
7176 We'd like to respect the convention that a function named
7177 "try-mumble" should behave just like the function called "mumble",
7178 but return #f instead of signalling some error.
7179 * load.h: Rename prototypes.
7181 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7183 * print.c (make_print_state, grow_print_state), print.h: Modified
7184 the print state representation: Don't use a tail array for
7185 recording of circular references. Resizing of the print state
7186 structure invalidates the print state pointer. To avoid passing
7187 around an indirect print state reference to all printing
7188 functions, we instead let the print state reference a resizable
7191 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7193 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7194 Don't crash when passed an improper list terminated by a
7195 non-immediate value.
7197 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7199 Allocate data for structures on an eight-byte boundary, as
7200 required by the tagging system.
7201 * struct.c (alloc_struct): New function.
7202 (scm_make_struct, scm_make_vtable_vtable): Call it.
7203 * struct.h (scm_struct_n_extra_words): Bump to 3.
7204 (scm_struct_i_ptr): New "field".
7205 * gc.c (scm_gc_sweep): When we need to free the data, use the
7206 information stored by alloc_struct to find the beginning of the
7207 block allocated to the structure, so we can free it.
7209 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7211 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7214 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7215 (scm_debug_info): New member: id.
7217 * stacks.c: Stacks are now represented as structs; Stacks have an
7218 id given to them by `start-stack'.
7219 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7221 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7222 Changed stack representation.
7224 * debug.c (scm_procedure_name): Try procedure property `name' for
7225 compiled closures aswell.
7227 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7229 * eval.c: scm_i_name moved to gsubr.c
7230 (scm_m_define): Record names of all kinds of procedure
7231 objects. (Earlier, only closures were recorded.)
7233 * procprop.h: Added declaration of scm_i_name.
7235 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7236 (scm_make_gsubr): Record names of compiled closures.
7238 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7240 * debug.c, debug.h: Removed obsolete code.
7242 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7243 stacks.c: Renamed regs --> scm_contregs.
7245 * print.c (scm_free_print_state): Cleanup print state before
7246 returning it to pool. It is better to do it here than in
7247 scm_prin1 since scm_prin1 is called often.
7249 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7250 s_set_source_property_x): Check that first argument is a pair or a
7253 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7254 scm_i_line, scm_i_column and scm_i_breakpoint global.
7256 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7257 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7260 * debug.h: Added debug object smob declaration and macro
7263 * configure.in: Build with backtrace.o and stacks.o if debug
7266 * Makefile.in: Added entries for new files: backtrace.c,
7267 backtrace.h, stacks.c and stacks.h.
7269 * symbols.c (scm_sym2ovcell): Fixed documentation.
7271 * _scm.h (min, max): Added.
7273 * async.c: Moved `min' macro to _scm.h.
7275 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7276 SCM_BACKTRACE_INDENT.
7278 * eval.c: Added new debug options `maxdepth' and `indent'.
7280 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7282 * print.h: Added selector SCM_PRINT_STATE.
7284 * print.c: New functions: scm_make_print_state,
7285 scm_free_print_state.
7287 * print.h: Added declarations for scm_make_print_state,
7288 scm_free_print_state.
7290 * debug.c (scm_m_start_stack): New acro.
7292 * debug.h: Small cleanup.
7294 * init.c (scm_boot_guile_1): Moved scm_init_debug below
7297 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

7322 More prototype-related changes from Marius Vollmer:
7323 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7324 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7325 * ports.h (ptobfuns): Added prototypes. This means some casting in
7327 * fports.c: Added casts for initializations, since the functions
7328 are defined to take FILE * as their stream argument, not SCM.
7329 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7330 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7331 to `char *str_data' to conform to prototype.
7333 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7335 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7337 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7339 * stime.c, stime.h: use SCM_P method.
7341 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7343 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7344 be given at least two arguments. Insist that lst's last element
7345 be a list, but don't make any requirements of its predecessors.
7347 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7349 * eval.c (scm_nconc2last): Revert last change; there seems to be
7350 other stuff going on here.
7352 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7354 * eval.c (scm_nconc2last): Make sure that each element of lst
7355 (which is a list of argument lists, except for the tail) is a
7356 proper list, i.e., finite and terminated by '().
7358 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7360 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7363 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7364 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7367 * vectors.c (scm_make_vector): Fill vectors with the undefined
7368 value, to help make Guile Scheme code more portable to other
7371 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7372 * symbols.h, tags.h: Doc fixes.
7374 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7376 * async.c (scm_take_signal): Doc fixes.
7378 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7380 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7381 want to subtract it from the modulus; we just want to leave it
7384 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7386 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7389 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7391 * throw.c (scm_catch_apply): Finished implementation of
7394 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7396 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7398 (scm_init_filesys): set "i/o-extensions" feature.
7401 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7403 * Makefile.in (root.o): Correct dependencies.
7405 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7407 * Makefile.in: Added dependency entry for root.o.
7409 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7410 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7412 * init.c (scm_start_stack): Set initial root continuation number
7415 * procs.c: New function: scm_thunk_p.
7417 * procs.h: Added declarations of scm_thunk_p.
7419 * root.c: Renamed `call-with-new-root' -->
7420 `call-with-dynamic-root'.
7421 (cwdr): Removed allocation of new root state. This should be done
7422 separately by use of scm_make_root.
7423 (scm_apply_with_dynamic_root): New function: Does what it
7424 sounds like. Needed when spawning threads.
7426 * root.h: Added member last_debug_frame to root state.
7427 Added #include "libguile/debug.h"
7429 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7430 arguments. The motivation is that code in root.c needs catch
7431 functionality, and we want to avoid code duplication.
7432 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7433 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7434 handlers that run without popping the stack into the dynwind
7437 * throw.h: Added prototypes for scm_catch_apply and
7440 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7442 * root.h (scm_root, scm_set_root): Decouple thread support details
7443 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7444 SCM_SET_THREAD_LOCAL_DATA.
7446 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7447 and tortoise scanning loop.
7449 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7451 * Makefile.in: Rebuild dependencies.
7453 * libguile.h: #include "libguile/print.h" before "smob.h", since
7454 the latter uses the print_state structure.
7456 * throw.c (scm_ithrow): Use the correct variable when checking to
7457 see if a given element of scm_dynwinds is a valid catch.
7459 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7460 structure, abort; don't just silently ignore the garbage.
7462 * _scm.h: #include "print.h" here, since it seems to be used just
7464 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7465 strports.c, unif.h: Don't #include "print.h".
7467 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7469 * feature.h (scm_loc_features): Removed external declaration.
7470 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7472 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7474 * feature.c (scm_init_feature): Added threads feature (needs to be
7475 initialized here, since features doesn't exist when
7476 scm_init_threads is called).
7478 * libguile.h: Added #include "libguile/../threads/threads.h".
7479 (This is a kludge to get thread support working. This should be
7482 * configure.in, acconfig.h: Added flags for thread support.
7484 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7487 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7488 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7491 * _scm.h: Added conditional #include "threads.h"
7493 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7494 SCM_THREADS_SWITCHING_CODE.
7496 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7497 allocate the basic dynamic root object.
7498 (scm_boot_guile): Added call to scm_init_root.
7500 * root.c, root.h: Added root smob.
7501 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7502 functions: Implements dynamic roots mostly according to spec in
7503 SCM manual. Main difference is that the second argument is a
7504 throw handler rather than an error "thunk".
7506 * root.h: Added declaration of scm_init_root.
7508 * root.c: Added #include "genio.h", #include "smob.h", #include
7509 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7511 (scm_init_root): Added #include "root.x".
7513 * throw.c: Added #include "stackchk.h"
7514 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7515 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7516 can be used in scm_call_with_new_root; Added reenabling of stack
7517 checking when catching a throw.
7519 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7521 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7523 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7524 element is not found, as per R4RS.
7526 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7528 * list.c: Doc fixes throughout.
7530 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7532 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7533 declare the char * to be const. Avoids a warning in rgx.c.
7535 * ports.h: spelling fix.
7537 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7540 * load.c (scm_sys_try_load_path): throw an error if file not found
7541 (like it says it in NEWS).
7543 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7545 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7546 PROPS slot to '(), not #f; it's an empty alist.
7548 * throw.h, throw.c: Use SCM_P instead of #if hair.
7550 Remove special support for uncaught throws; see throw.c for
7552 * throw.c (uncaught_throw): New function.
7553 (scm_ithrow): Call uncaught_throw if we don't find a throw
7554 target; don't mess with scm_bad_throw_vcell.
7555 (scm_bad_throw_vcell): Variable deleted.
7556 (scm_init_throw): Don't initialize it.
7558 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7561 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7563 * numbers.c (scm_istr2int): If the number is short (as most
7564 numbers are), just call scm_small_istr2int to deal with it.
7565 (scm_small_istr2int): New function, created by un-#ifdefing the
7566 non-bignum version of scm_istr2int and renaming it.
7568 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7570 * load.c (scm_sys_try_load): don't check whether value returned
7571 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7572 Change the Scheme name from %try-load to primitive-load.
7574 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7575 Can avoid passing a message, allowing it to be derived in the
7576 error handler (e.g., if we want to throw to the key both from
7579 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7581 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7582 references now have a new appearance which is more compact and
7583 also gives a clue about what the target of the reference is.
7584 By setting parameters in the print state, more fancy printing can
7585 be achieved. This is used by the (not yet commited) backtrace
7588 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7590 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7593 * print.c: Added #include "struct.h". Removed function
7596 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7597 scm_iprin1. Removed prototype for scm_prlist.
7599 * arbiters.c (prinarb),
7600 async.c (print_async),
7601 debug.c (prindebugobj, prinmemoized),
7602 eval.c (prinprom, prinmacro),
7603 filesys.c (scm_fd_print, scm_dir_print),
7605 mallocs.c (prinmalloc),
7606 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7607 smob.h (scm_smobfuns),
7608 srcprop.c (prinsrcprops),
7610 unif.c, unif.h (scm_raprin1, rapr1),
7611 variable.c (prin_var): Changed argument `int writing' to
7612 `scm_print_state *pstate'.
7614 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7615 that it will be called before scm_init_print.
7617 * print.c (scm_prin1): Print states are now allocated when calling
7618 scm_prin1 and then passed around to all printing functions as an
7619 argument. A cache `print_state_pool' enables reuse of print
7621 (scm_make_print_state): New function.
7622 (scm_iprin1): Adaption to print states.
7623 (scm_iprlist): An initial "hare and tortoise" scan brings down
7624 time complexity to O (depth * N). (Better time complexity will be
7625 achieved when the printing code is completely rewritten.)
7627 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7629 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7630 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7631 it gets done whether or not the cache variable has a value.
7633 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7635 Distinguish #f and ().
7636 * __scm.h: #undef SICP.
7637 * pairs.h (SCM_EOL): Delete this definition, equating it with
7639 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7640 the value it used to have. Doc fixes, too.
7642 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7644 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7645 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7646 Lord's implementation of structs, allowing for tail arrays as
7647 described in the manual. Also fixed some bugs. (Both the interface
7648 and the implementation should be improved.)
7650 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7652 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7653 People who whish to see the source can do `(print-enable 'source)'.
7654 Removed #ifdef DEBUG_EXTENSIONS.
7656 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7658 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7659 integer (assuming for now accepting an integer is a good thing).
7661 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7662 %S will be used instead for write'ing arguments.
7664 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7665 asserts. fix a few other asserts.
7666 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7667 scm_uniform_vector_ref, scm_array_set_x,
7668 scm_dimensions_to_unform_array): change args in
7669 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7670 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7671 scm_substring_fill_x): likewise.
7672 gsubr.c (scm_gsubr_apply): likewise.
7673 eval.c (SCM_APPLY): likewise.
7675 * eval.c (4 places): replace scm_everr with lgh_error or
7678 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7679 scm_memory_error): new procedures.
7680 scm_everr: deleted. can use scm_wta, dropping first two args.
7681 scm_error: convert NULL subr to SCM_BOOL_F.
7683 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7686 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7689 * error.c, error.h: new error keys: scm_arg_type_key,
7690 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7692 scm_wta: reimplement using lgh_error instead of scm_everr.
7694 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7696 * gdbint.c: scm_lread now has one more argument.
7698 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7699 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7700 loading source from non-file ports, which, e. g., happens when
7701 using the Emacs interface).
7703 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7706 * read.c: Added code for recording of positions of source code
7707 expressions; New functions: recsexpr, scm_lreadrecparen;
7708 _scm_make_srcprops --> scm_make_srcprops
7709 (scm_flush_ws): Removed updating of positions counters. This work
7710 is already done by scm_gen_getc
7712 * read.h: Added prototype for scm_lreadrecparen
7714 * print.c: Added #include "alist.h"
7716 * eval.c: Added #include "hash.h"
7718 * eq.c: Added #include "ramap.h"
7720 * options.c: Documentation fixes.
7722 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7723 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7724 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7725 --> scm_make_srcprops
7727 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7728 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7729 function calls in the definition of the whash access macros.
7731 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7733 * init.c (scm_boot_guile): Add level of indirection to
7734 scm_boot_guile_1() to ensure that stack base pointer is properly
7735 initialized. There was no guarantee that variable i was the
7736 highest/lowest variable on stack (i.e. the call frame of
7737 scm_boot_guile was not completely protected from gc).
7739 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7741 * ports.h (scm_port_table): put back file_name, it will be used to
7742 support debugging. Undo related changes in fports.c, ioext.c,
7745 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7747 * ports.h (scm_port_table): remove file_name member for now, it seems
7749 * fports.c (scm_open_file): don't set file_name in PTAB.
7750 (prinfport): don't use file_name in PTAB.
7751 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7752 * ports.c (scm_add_to_port_table): don't intialize file_name.
7753 (scm_port_file_name): remove for now.
7754 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7756 * fports.h (scm_mkfile): prototype deleted.
7757 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7759 * debug.c, unif.c: use scm_out_of_range instead of
7760 wta for range errors (ASSERT still needs work).
7762 * error.c, error.h (scm_out_of_range): new procedure.
7764 * error.c, error.h (scm_out_of_range_key): new key.
7766 * posix.c (scm_sync): #else was missing.
7768 * error.c, error.h: append _key to names scm_num_overflow and
7771 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7772 of consing an empty list.
7773 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7774 of macros, saves code and string space.
7775 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7776 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7777 lower case. Rename scm_syserror_m to scm_syserror_msg.
7778 error.h: prototypes for new procedures.
7780 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7782 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7784 * error.c, error.h: setup scm_num_overflow key.
7786 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7787 Remove definition of SCM_OVSCM_FLOW.
7789 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7791 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7792 explicit message and args.
7794 * error.c, error.h, __scm.h: change system_error_sym to
7797 * error.c (system_error_sym): remove leading %% from the Scheme name
7800 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7802 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7804 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7805 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7806 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7807 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7808 renamed. (These were introduced by unsupervised name
7811 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7813 * print.c: Added code for detection of circular references during
7814 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7815 a hook for printing of closures (accessible via print options).
7816 This leads to a split of calls to scm_iprin1 into two classes:
7817 elementary print operations (e. g. the code which prints a smob)
7818 still use scm_iprin1 while top level calls (like scm_display) use
7819 scm_prin1. scm_prin1 begins by clearing the data structure used
7820 to record reference information.
7822 * print.h: Added declarations of scm_prin1 and scm_prlist.
7824 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7826 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7828 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7830 * error.c (err_head): scm_iprin1 --> scm_prin1
7832 * debug.c: Adjusted header comment.
7836 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7838 * strerror.c: Doc fix.
7840 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7842 * gdbint.c (gdb_read): Now possible to run during GC.
7843 (unmark_port, remark_port): New functions.
7845 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7847 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7848 of allocating a new string object. Also, increase size by
7849 the factor 2 instead of 1.5.
7851 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7853 * __scm.h (SCM_P): Corrected to run under traditional C.
7855 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7858 * async.c: Calls to scm_sysintern corrected.
7860 * async.h (scm_async_clock): Redundant declaration removed.
7862 * continuations.c (scm_dynthrow): Redundant declaration removed.
7864 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7865 Definition typos corrected.
7867 * debug.h: Missing declarations of functions in debug.c added
7870 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7871 Missing declarations to functions in eval.c added.
7873 * filesys.c: Possibly uninitialized variable rv.
7875 * gc.h (scm_object_addr, scm_unhash_name): Missing
7876 declarations of functions defined in gc.c added.
7878 * genio.c: Possible typos str_data -> wstr_data. ???
7880 * genio.c: Possibly unintended shadowing of local variable
7881 `int c' (gotos out of scope of inner `c'). ???
7883 * init.c: Uninitialized `SCM last' may be used.
7885 * ioext.h: (scm_sys_isatty_p): Typo.
7887 * list.h (scm_list_head): Missing prototype for function in
7890 * numbers.c (scm_two_doubles): Changed from extern to static
7891 (is used only within numbers.c).
7893 * numbers.h: Repeated declarations removed.
7895 * ports.h (scm_close_all_ports_except): Declaration for the
7896 function defined in ports.c added.
7898 * posix.h: Missing declarations added.
7900 * procs.h (scm_make_subr_opt): Missing declaration added.
7902 * socket.h (scm_sys_gethost): Missing declaration added.
7904 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7906 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7907 Missing declarations added.
7909 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7911 * struct.c: Uninitialized variable `SCM answer' may be used.
7913 * unif.c (l2ra): Declaration prototype.
7915 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7916 defined in ramap.c).
7918 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7919 Redundant declarations removed (they are in ramap.h).
7921 * variable.h (scm_make_udvariable,
7922 scm_make_undefined_variable): Declaration corrected to
7923 correspond variable.c.
7925 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7926 Missing declarations added.
7928 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7930 * Makefile.in (distclean): Don't forget to delete fd.h.
7932 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7934 * fd.h.in, tags.h: Trivial cleanups.
7936 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7937 marksweep.h just declared functions from gc.c.
7938 * gc.h, libguile.h: Don't #include "marksweep.h".
7939 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7940 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7941 dependencies updated.
7943 * libguile.h: Don't #include "files.h"; it's been deleted.
7945 * files.c (scm_sys_delete_file): Moved to filesys.c.
7946 File is now empty; deleted.
7948 * filesys.c: scm_sys_delete_file is now here. Remove
7949 #if's; they seem to rely on remnants of an old portability
7950 regimen. If the problems come up again, solve them properly,
7951 using autoconf. Specifically: Don't test M_SYSV, and #define
7952 remove to be unlink if it's #defined; don't use remove just
7953 because HAVE_STDC_HEADERS is #defined.
7954 * filesys.h: Add declarations for scm_sys_delete_file.
7955 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7956 files.o, files.h, files.c, and files.x.
7957 * init.c: Don't #include "files.h", and don't call scm_init_files.
7959 Use SCM_P instead of PROTO; the latter intrudes on the user's
7961 * params.h: Deleted; definition of SCM_P moved to...
7962 * __scm.h: ... here, where it replaces PROTO macro.
7963 * libguile.h, smob.h: Don't #include "params.h".
7964 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7965 smob.h: Fix prototypes accordingly.
7966 * Makefile.in: Update dependencies.
7967 (inner_h_files): Remove params.h.
7969 * gc.c: #include "gc.h"; every module should include its header,
7970 to let the compiler cross-check the declarations against the
7973 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7974 simpos.h: #include "libguile/__scm.h".
7976 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7978 * init.c: Don't forget to #include smob.h and init.h.
7979 * Makefile.in: Dependencies updated.
7981 * smob.h: Use PROTO instead of #if __STDC__.
7983 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7985 * __scm.h: Doc fixes.
7987 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7988 <angles>; this allows `make depends' to work properly.
7990 * libguile.h: #include smob.h and pairs.h before the others; they
7991 define typedefs used by other headers.
7993 C files should #include only the header files they need, not
7994 libguile.h (which #includes all the header files); the pointless
7995 recompilation was wasting my time.
7996 * Makefile.in (all .o dependency lists): Regenerated.
7997 * libguile.h: Don't try to get a definition for size_t here...
7998 * __scm.h: Do it here.
7999 * _scm.h: Since this is the internal libguile header, put things
8000 here that all (or a majority) of the libguile files will want.
8001 Don't #include <libguile.h> here; that generates dependencies on
8002 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
8003 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
8004 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

8100 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
8101 * weaks.c: Get "weaks.h".
8103 * stackchk.h: #include "libguile/debug.h",
8105 * print.h, read.h: #include "options.h", since everyone who uses
8106 either of these files will need that.
8108 * smob.h: #include "ports.h", "genio.h", and "print.h", since
8109 anyone who uses this file will need them to define the smob
8110 printing functions. Also, get markers.h, since people will need
8111 to #define the mark functions.
8113 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
8114 * ports.h: ... to here.
8116 * ports.h (scm_port_table_size): Explicitly give type as 'int';
8117 don't rely on archaic C default type rules.
8119 * fports.h: #include "libguile/ports.h", since you need that in
8120 order to parse this.
8122 * genio.h: #include "libguile/print.h", because you need that to
8123 parse this; don't bother #including "ports.h", since print.h gets
8126 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
8128 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
8129 this; it's now a reference to an element of *scm_root.
8131 * debug.h: Don't #include "options.h"; the compiler won't be able
8132 to find that once the headers are installed; instead, #include
8133 "libguile/options.h".
8134 * gc.h: Same, with marksweep.h.
8135 * mbstrings.h: Same, with symbols.h.
8136 * scmhob.h: Same, with _scm.h.
8137 * smob.h: Same, with params.h.
8139 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
8140 C files; there's no need for this, and it forces recompilations
8143 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
8145 * error.c (scm_error): declare scm_error_callback.
8147 * error.h: prototype for scm_error_callback.
8149 * __scm.h: define lgh_error.
8150 (SCM_SYSERROR): redefine using lgh_error.
8152 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
8154 * error.c (scm_error): new procedure.
8156 * error.h: prototype for scm_error.
8158 * Makefile.in (install): install scmconfig.h from the current
8159 directory, not $(srcdir).
8161 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8163 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8164 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8165 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
8166 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
8167 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
8168 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8169 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8170 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8171 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8172 vports.h, weaks.h: #include "libguile/__scm.h", not
8173 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
8174 dependencies are within libguile properly.
8176 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8178 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8179 when scmconfig.h doesn't exist.
8181 * load.c (scm_sys_try_load): Correct spelling.
8183 * feature.c (scm_loc_features): Make this static.
8185 * Makefile.in (libpath.h): Omit trailing slash from path. We
8186 shouldn't require it of users, so why put it here?
8188 Move code to initialize and search %load-path from ice-9 to C
8189 code, so we can use the load-path to find the ice-9 boot code;
8190 this makes it easier to run Guile without installing it. See
8191 corresponding changes in guile/Makefile.in.
8192 * feature.c: Move stuff concerned with the load path to load.c.
8193 (scm_compiled_library_path): Deleted.
8194 Don't #include libpath.h here.
8195 * feature.h: Don't mention scm_compiled_library_path.
8196 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8197 <sys/stat.h>, and <unistd.h> (if present).
8198 (R_OK): #define if the system hasn't deigned to.
8199 (scm_loc_load_path): New variable.
8200 (scm_init_load_path, scm_sys_search_load_path,
8201 scm_sys_try_load_path): New functions.
8202 (scm_init_load): Initialize scm_loc_load_path to point to the
8203 value cell of the Scheme %load-path variable.
8204 * load.h: Add declarations for scm_sys_search_load_path,
8205 scm_sys_try_load_path.
8206 * init.c: Call scm_init_load_path.
8207 * Makefile.in (feature.o, load.o): Dependencies updated.
8209 * load.c, load.h: Rewrite using PROTO macro.
8211 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8213 * gc.c (scm_cellp): New function: C predicate to determine if an
8214 SCM value can be regarded as a pointer to a cell on the heap.
8216 * gc.h: Added declaration of scm_cellp.
8218 * gdb_interface.h: New file: The GDB interface header from the GDB
8221 * gdbint.c: New file: GDB interface.
8223 * gdbint.h: New file: GDB interface.
8225 * libguile.h: Added #include <libguile/gdbint.h>.
8227 * init.c (scm_boot_guile): Added scm_init_gdbint.
8229 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8230 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8231 found if object files and source are kept separate).
8233 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8235 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8237 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8239 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8240 TK_SRC_DIR; they're not relevant any more.
8242 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8243 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8245 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8247 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8248 search path, so we can find the <libguile/MUMBLE.h> headers.
8250 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8252 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8253 implicit in the .c.o rule.
8254 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8257 Put the library path in a header file, instead of passing it on
8258 the command line in every compilation.
8259 * Makefile.in (libpath.h): New target.
8260 (feature.o): Depend on libpath.h.
8261 (clean): Delete libpath.h.
8262 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8263 * feature.c: ... #include "libpath.h" here.
8264 * .cvsignore: Ignore libpath.h.
8266 Don't install the unwashed masses of Guile header files in the
8267 main #include path; put most of them in a subdirectory called
8268 'libguile'. This avoids naming conflicts between Guile header
8269 files and system header files (of which there were a few).
8270 * Makefile.in (pkgincludedir): Deleted.
8271 (innerincludedir): New variable; this and $(includedir) are enough.
8272 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8273 (installed_h_files): Divide this up. Now this variable lists
8274 those header files which should go into $(includedir) (i.e. appear
8275 directly in the #include path), and ...
8276 (inner_h_files): ... this new variable says which files appear in
8277 a subdirectory, and are referred to as <libguile/mumble.h>.
8278 (h_files): List them both.
8279 (install): Create innerincludedir, not pkgincludedir. Put
8280 the installed_h_files and inner_h_files in their proper places.
8281 (uninstall): Corresponding changes.
8282 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8283 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8284 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,

8290 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8291 vports.h, weaks.h: Find __scm.h in its new location.
8292 * __scm.h: Find scmconfig.h and tags.h in their new locations
8293 (they're both "inner" files).
8295 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8297 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8299 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8301 * posix.c: Doc fixes.
8303 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8305 * socket.c: Don't include a prototype for inet_aton; just use a
8306 K&R style declaration, to avoid warnings but minimize the chance
8307 of conflicts with the system.
8309 On NextStep, <utime.h> doesn't define struct utime, unless we
8310 #define _POSIX_SOURCE before #including it.
8311 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8312 * acconfig.h: New comment text for above CPP symbol.
8313 * configure.in: Call it.
8314 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8316 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8318 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8319 testing for __EMX__.
8321 * posix.c: #include <libc.h>, if it exists.
8323 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8324 don't even know if the latter exists.
8326 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8327 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8328 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8330 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8332 (scm_init_posix): Use them when initializing the Scheme constants
8335 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8337 * Makefile.in (libdir, includedir, bindir): Use the
8338 autoconf-supplied values, instead of deriving them ourselves.
8339 (pkgincludedir, datadir, pkgdatadir): New variables.
8340 (install, uninstall): Put the header files in a special
8341 subdirectory, not in the main search path.
8343 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8344 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8346 * Makefile.in (IMPLPATH): Deleted; never used.
8348 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8349 on the Tcl/Tk source any more.
8350 (INCLUDE_CFLAGS): Remove references to the above.
8352 * Makefile.in (version.o): Corrected dependencies.
8354 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8356 * libguile.h: #include "version.h"
8358 * init.c (scm_boot_guile): Call scm_init_version.
8359 * gscm.c (gscm_run_scm): Call scm_init_version.
8361 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8362 GUILE_VERSION): AC_DEFINE these.
8363 (acconfig.h): #undef the above symbols.
8365 * Makefile.in (libobjs): Add version.o.
8366 (installed_h_files): Add version.h.
8367 (c_files): Add version.c.
8368 (gen_c_files): Add version.x.
8369 (version.o): New rule.
8370 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8371 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

8379 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
8380 weaks.o): Add version.h to dependency lists.
8381 (markers.o): Remove duplicate rule.
8383 * version.h: New file.
8385 * version.c: New file.
8387 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8389 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8390 array; use it appropriately. Since GCC is quite happy to
8391 subscript functions, it never warned us about this; we should use
8392 -Wpointer-arith in the future. I guess we never tested
8395 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8397 * socket.c: Doc and copyright fixes.
8399 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8401 * debug.c: Fixed and improved gdb support.
8403 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8405 * socket.c: Added declaration of inet_aton to avoid compiler
8406 warning. (Hope this solution is correct.)
8408 * stime.c: Added declaration of ftime. (This is missing in
8411 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8413 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8415 * Makefile.in (c_files): add strerror.c.
8417 * strerror.c: new file from Emacs' sysdep.c.
8418 maybe configure should also check for sys_errlist.
8420 * configure.in (AC_REPLACE_FUNCS): add strerror.
8422 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8424 * debug.c (scm_init_debug): Added initialization for
8425 scm_evaluator_traps.
8427 * debug.h, debug.c: Various name changes.
8428 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8429 "debug-options-interface". See commentary in options.c.
8431 * options.h, options.c: Options now have documentation strings.
8432 Also added a long explanatory commentary.
8434 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8437 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8438 last_debug_info_frame is now updated in all cases.
8440 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8443 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8445 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8446 Added option STACK_CHECKING.
8448 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8450 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8452 * __scm.h: Removed symbols for debugging support.
8454 * acconfig.h: Added symbols for debugging support.
8456 * configure.in: Added user option for debugging support.
8457 --enable-debug will include the debugging code into libguile.a.
8459 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8460 scm_relocate_chunk_to_heap.
8462 * debug.c: New file: low-level debugging support. It also
8463 includes support for debugging with gdb. (The extensions to gdb
8464 are written by Per Bothner at Cygnus.)
8466 * debug.h: New file: low-level debugging support.
8468 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8469 argument pairs. Extensive modifications to the debugging
8470 evaluator. Added "SECTION:" commentaries to clarify what happens
8471 when, during double compilation. Renamed EVALIMP --> EVALIM.
8472 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8473 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8474 the beginning of the file. New procedure: scm_unmemocopy.
8475 Added some global state variables needed by the debugging
8476 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8477 check_entry, check_apply, check_exit, debug_options and
8478 evaluator_traps. New acro: undefine.
8480 * eval.h: Renamed EVAL --> XEVAL.
8482 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8483 --> scm_make_weak_key_hash_table.
8485 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8486 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8488 * libguile.h: Conditionally include debug.h
8490 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8491 scm_object_properties shouldn't return handle. `handle' now gets
8492 initialized in scm_set_object_properties_x. scm_object_properties
8493 doesn't any longer create an entry in scm_object_whash.
8495 * options.c: New file: handling of run time options.
8497 * options.h: New file: handling of run time options.
8499 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
8501 * print.c: New procedure: scm_print_options
8503 * print.h: Defines for print options.
8505 * read.c: New procedure: scm_read_options
8507 * read.h: Defines for reader options.
8509 * root.h: Added scm_source_whash among scm_sys_protects.
8511 * srcprop.c: New file: source properties.
8513 * srcprop.h: New file: source properties.
8515 * throw.c (jbsmob): Jump buffers are now correctly allocated.
8516 (Bug found by A. Green.)
8518 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8520 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8522 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8524 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8526 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8527 and should be called by the final client.
8529 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8531 * gc.h: Use the PROTO macro when declaring functions.
8532 * gc.c: Use the PROTO macro when declaring static functions.
8533 Remove the CPP hair around function definitions.
8535 * gc.c (scm_init_storage): Initialize scm_asyncs.
8537 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8538 preprocessor symbol; "__scm.h" is where it might get #defined.
8539 * __scm.h: Similar: #include <scmconfig.h> before testing
8542 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8544 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8546 * init.c (scm_boot_guile): Add init_func argument; call
8547 (*init_func) instead of calling scm_appinit; it's ucky to
8548 hard-code names for the user's procedures.
8549 * init.h (scm_boot_guile): Adjust declaration.
8551 * __scm.h (PROTO): New macro, for declaring functions with
8554 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8555 eliminate all the __STDC__ conditionals.
8556 (scm_boot_guile): Add declaration.
8557 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8558 Remove __STDC__ conditionals around function definitions; the
8559 declarations in init.h will provide the same information, more
8562 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8563 complain about it in the error message; the error message is
8564 adequate without that note, and there's nothing the user can do
8567 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8569 * Makefile.in (ancillary): Drop def.sed.
8571 * posix.c (scm_init_posix): Use numeric values, rather than
8572 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8573 F_OK. The symbols aren't available on some systems, and I'm
8574 pretty sure their values are fixed by common widespread practice.
8575 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8577 More functions unavailable on some systems.
8578 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8579 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8581 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8582 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8583 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8584 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8585 stub that signals an error as the #else.
8587 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8589 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8591 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8593 * unif.c: include ramap.h.
8595 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8597 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8599 * ports.c: include sys/ioctl.h.
8601 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8603 * configure.in: check for sys/ioctl.h.
8605 * ports.c: include <malloc.h> not "malloc.h".
8607 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8609 * fports.c: remove ttyname and tmpnam declarations.
8611 * posix.c: fewer ttyname declarations.
8613 * fports.c: include <string.h> not "string.h".
8615 * init.c, ioext.c: include string.h and unistd.h.
8617 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8619 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8620 genio.c, simpos.c, vports.c: include string.h.
8622 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8624 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8626 (scm_addr_buffer_size): change type from scm_sizet to int.
8627 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8628 from scm_sizet to int.
8630 * error.c: include unistd.h.
8632 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8635 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8637 * __scm.hd, def.sed: deleted.
8639 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8641 Changes for NeXT, suggested by Robert Brown.
8642 * configure.in: Call AC_TYPE_MODE_T.
8643 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8644 NeXT. Put header file list in alphabetical order.
8645 * configure, scmconfig.h.in: Regenerated.
8646 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8648 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8651 * acconfig.h: New file, providing documentation for the CPP
8652 symbols defined in configure.in
8653 * acconfig-1.5.h: Removed; superceded by the above.
8655 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8657 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8659 * fports.c (scm_open_file): don't return #f, throw error.
8661 * ioext.c (fileno): renamed from %fileno.
8662 (soft-fileno): deleted.
8664 * ports.c (scm_port_revealed): don't need to check for -1 from
8666 (scm_set_port_revealed_x): return unspecified, not #f.
8668 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8670 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8672 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8674 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8676 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8678 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8679 This is necessary on Ultrix, and doesn't hurt portability.
8681 * Makefile.in (dist-dir): New target, implementing a new dist system.
8682 (installed_h_files): Put in alphabetical order.
8683 Remove duplicate entries for markers.h and unif.h.
8684 (c_files): Remove duplicate entries for markers.c.
8685 (ancillary): Renamed from anillery; all uses changed. Remove
8686 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8687 Remove all the ../doc/* files; doc/Makefile.in handles that.
8689 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8691 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8692 every if must have an else, or else the whole command has a
8693 non-zero exit code whenever the if's condition is false.
8695 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8697 * posix.c: include string.h.
8699 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8701 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8704 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8705 Remove leading % from scheme names.
8706 Do not return error values, call SCM_SYSERROR or similar.
8708 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8710 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8712 * struct.c (scm_init_struct): new file.
8714 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8716 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8717 (scm_list_head): added list-head for rapidly chopping argument
8718 lists off of longer lists (and similar).
8720 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
8722 * objprop.c (scm_object_property): assq the cdr of the whash
8723 handle for obj, not the handle itself.
8725 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8727 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8728 weak hash tables last of all marking to avoid an obscure gc bug.
8729 WARNING: circular lists stored in a weak hash table will hose us.
8731 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8733 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8734 new functions similar to scm_substring_move_left_x and
8735 scm_substring_move_right_x.
8737 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8739 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8742 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8744 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8746 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8748 * strports.c (scm_strprint_obj): convenience function. C for
8749 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8751 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8752 removed to a separate library
8754 * init.c (scm_boot_guile): copied from guile-tcl.c.
8755 Initialization specific to tcl interpreters removed.
8757 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8759 * ports.c (scm_ports_prehistory): size malloced here doesn't
8760 matter so long as it is non-0 (got rid of "* 4").
8762 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8764 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8765 since its definition was bogus).
8767 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8769 * mallocs.[ch]: back again (for rx at least).
8771 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8773 * ports.c: removed functions relating to the mapping between ports
8774 and descriptors. (That stuff is unix-specific and should be collected
8775 in a separate library).

8952 initialization to fix a race condition.
8954 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
