8 * random.c: Removed alloca includes.
10 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
12 * Makefile.in: This changed, for some reason I don't really
13 understand, when I ran automake in the top level directory. This
14 may be contamination by Cygnus internal releases. If you re-run
15 automake and this change gets reverted, don't worry about it.
17 1999-01-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

33 Interface same as slib's.
35 * Makefile.am: Added random.c, random.h, random.x.
37 * init.c: #include "random.h";
38 (scm_boot_guile_1): Call scm_init_random ().
40 1998-12-23 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
42 * Makefile.am: New files: guardians.c, guardians.x, guardians.h
44 * guardians.c, guardians.h (scm_make_guardian,
45 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
46 scm_get_one_zombie, scm_init_guardian): This is an implementation
47 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
48 David Eby (1993) "Guardians in a Generation-Based Garbage
49 Collector" ACM SIGPLAN Conference on Programming Language Design
50 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
51 /pub/scheme-repository/doc/pubs/guardians.ps.gz
52 Author: Michael N. Livshin.
54 * gc.h (SCM_MARKEDP, SCM_NMARKEDP): New macros.
56 * gc.c (scm_igc): Call scm_guardian_gc_init and
59 * init.c (scm_boot_guile_1): Call scm_init_guardian.
61 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
63 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
66 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
68 Move the procedure slots of entities to invisible slots (so that
69 we can have operator class objects which themselves are entities).
70 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
71 SCM_STRUCTF_ENTITY): New constants.
73 * struct.c (scm_make_struct): Allocate "invisible" room for
74 procedures if SCM_STRUCTF_ENTITY is set in vtable.
76 * gc.c (scm_gc_mark): Mark entity procedures.
78 * struct.c, struct.h (scm_alloc_struct): Renamed from alloc_struct
80 (scm_struct_init): Renamed from init_struct and made global.
82 * objects.h (SCM_ENTITY, scm_entity): Removed.
83 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
84 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
86 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
88 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
89 of syntactic forms, similar to SCM_PROC.
90 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
91 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
92 for the name symbols when needed.
94 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
96 * Makefile.in: Regenerated.
98 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
100 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
101 take the address of _into; it might be a register. Just have
102 scm_debug_newcell return the new cell.
103 * gc.c (scm_debug_newcell): Just return the new cell, instead of
104 taking the address of a place to store it as an argument.
105 * gc.h (scm_debug_newcell): Change declaration.
106 (Thanks to Greg Harvey.)
108 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
110 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
111 Replaces old names serial-array-copy! and serial-array-map!.
113 * evalext.c (map-in-order): New name. Replaces serial-map.
115 1998-12-05 Jim Blandy <jimb@totoro.red-bean.com>
117 * smob.c (freeprint): New function.
118 (freecell): Use it to print freed objects, for slightly easier
121 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
123 * backtrace.c (display_frame): Made more robust. Doesn't throw an
124 error if no source properties can be found for a frame. (Thanks
125 to Christian Lynbech.)
127 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
129 * objects.h: Removed slots direct_supers and direct_slots from the
130 definitions of the rudimentary classes described by objects.h.
132 * objects.c, objects.h (scm_entity_p): New procedure. Together
133 with the predicates scm_procedure_p and scm_struct_p, this
134 predicate makes it possible to differ between structs, entities
137 * modules.c, modules.h (scm_resolve_module): New function.
139 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
141 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
142 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
145 * objects.c (scm_entity_p): New procedure.
147 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
148 for asubrs, rpsubrs, lsubrs and lsubr_2s.
150 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
152 * procprop.h (scm_i_procedure_arity): Added declaration.
154 * procprop.c (scm_i_procedure_arity): Made global; New code to
155 handle operators and entities.
156 (scm_procedure_property): No need to call scm_procedure_p since
157 scm_i_procedure_arity now does all necessary type checking.
158 Added #include "objects.h".
160 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
161 s_add_hook_x --> s_remove_hook_x.
162 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
163 Added #include "procprop.h"
165 * feature.c, feature.h (scm_reset_hook_x): New procedure.
166 (scm_make_hook): Optional argument defines number of arguments to
168 (scm_make_named_hook): Take number of args as second arg.
169 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
170 boot-9.scm for a while); First arg is the hook. The rest are
171 arguments passed on to the hook procedures.
173 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
175 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
176 scm_logbit_p): Do the computation in ulongs. This is not as nice
177 as doing it in bignums, but at least it's good enough for
178 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
180 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
181 subexpressions. (Thanks to Charbel Jacquin.)
183 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
185 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
186 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
187 (scm_make_named_hook): New function.
189 * feature.c: Added #include "eval.h".
191 * modules.c (scm_make_module): Beautify the module.
193 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
195 * modules.c, modules.h: New files: C interface to modules. (This
196 is necessary in order to interface the object system to Guile
197 properly. The guts of these modules will be replaced by the new
198 module system in the future.)
200 * init.c: Added #include "modules.h"
201 (scm_boot_guile_1): Call scm_init_modules.
202 (invoke_main_func): Call scm_post_boot_init_modules.
204 * Makefile.am: Added modules.c, modules.x, modules.h.
206 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
208 * procs.c: #include "objects.h"
209 (scm_procedure_p): Return #t also on structs which are operators.
211 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
212 <operator-metaclass> and <entity-class> to <standard-class>,
213 <operator-class> and <entity> in order to conform with STKlos
216 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
217 which isn't an operator.
218 (SCM_APPLY): Ditto, but jump to badproc.
220 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
222 * eval.c (SCM_CEVAL): Allow structs implanted in code.
223 Previously, structs implanted in code were interpreted as forms
224 the operator of which was a gloc. We solve this by checking for
225 the zero in the emulated vcell in the struct vtable. Since
226 implanted structs always will look like forms with a gloc
227 operator, execution will only be slowed down by maximally one
228 extra test-and-branch per application.
230 * evalext.c (scm_definedp): Removed check for isyms; Added a
231 second optional argument: It is now possible to supply an
232 evaluation environment in which to look for the symbol.
234 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
236 * readline.c (scm_init_readline): Set
237 rl_basic_word_break_characters. (Thanks to Ian Grant.)
239 * coop.c (coop_condition_variable_wait): Removed
240 (coop_condition_variable_wait_mutex): Folded logic of
241 coop_mutex_unlock into coop_condition_variable_wait_mutex to
242 prevent condvar signal lossage. Previously, another thread could
243 start to run after unlocking the mutex but before putting the
244 current thread on the wait queue. If that thread then would
245 signal the first, the signal would be lost. (Thanks to Christian
248 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
250 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
253 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
255 * objects.c (scm_i_make_class_object): Renamed from
256 make_class_object; exported; error checking moved to
257 scm_make_class_object and scm_make_subclass_object.
258 (scm_make_class_object, scm_make_subclass_object): Use
259 scm_i_make_class_object.
260 (scm_make_subclass_object): Let the subclass have same metaclass
263 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
265 * debug.c (scm_debug_options): Bugfix: Set the value of
266 scm_stack_checking_enabled_p after setting debug options;
267 #include "stackchk.h". (Thanks to Richard Polton.)
269 1998-11-13 Radey Shouman <rshouman@metro2000.com>
271 * unif.c (scm_array_contents): removed unnecessary test for 0
274 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
276 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
277 Replaced by macro `collect' in boot-9.scm.
279 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
281 * eval.c (scm_copy_tree): Copy source properties if existent.
283 * debug.c (scm_start_stack): Copy source when evaluating. (If we
284 don't, we may end up passing memoized source to a transformer.)
286 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
288 * stack.c (get_applybody): Help function which lookups the first
289 body form of the apply closure.
290 (read_frames): Prevent the source of the first form of the apply
291 closure from being recorded. This would only be confusing.
293 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
294 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
296 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
298 * stacks.c (read_frame): Bugfix: Removed lingering `else'
300 (read_frames): Use SCM_MACROEXPP.
302 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
304 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
305 don't contain interesting information since all arguments are
306 present in the frame which applies the compiled closure anyway.);
307 Skip the transformer application frames.
309 * print.c (scm_iprin1): Print gsubrs as primitives.
311 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
313 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
315 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
316 that we can identify these in a backtrace. (This change doesn't
317 introduce any significant speed penalty.)
319 * eval.c: Added note about `serial-map' using scm_map.
321 * read.c, read.h (scm_read_options, scm_read_opts): Removed
322 readline options. They should reside in their own options array.
324 * readline.c, readline.h (scm_readline_options,
325 scm_readline_opts): Moved readline options here.
327 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
329 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
330 SCM_ROCHARS instead of SCM_CHARS.
332 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
333 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
335 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
337 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
338 This is quite important since the latter clears the
339 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
340 every single character read...
342 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
344 * print.c (scm_iprin1): Removed suspect looking (and indeed
345 malevolent) semicolon after test for user supplied closure print
346 procedure. (Thanks to Telford Tendys.)
348 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
349 (scm_memq, scm_memv, scm_member): Do argument checking *before*
350 starting to search the list. Removed call to sloppy_mem_check.
352 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
353 procedures: Same as scm_delq_x et al, but delete maximally one
356 * options.c (scm_options, scm_init_options): GC-protect option
357 values of type SCM. (Thanks to Telford Tendys.)
359 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
361 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
362 make sure that there always is a "real" scm_lookupcar.
364 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
366 * read.c, read.h (scm_read_opts): New read options
367 "history-length" and "history-file".
368 (scm_read_options): Stifle history to history length.
370 * readline.c (scm_read_history, scm_write_history): New procedures.
372 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
374 * eval.h (scm_macro_eval_x): Removed declaration.
376 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
377 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
378 Renamed and made global.
380 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
381 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
383 * evalext.c, evalext.h: New files. Contain non-R5RS things
384 having to do with evaluation.
386 * evalext.c (scm_serial_map): New procedure: Version of `map'
387 which guarantees that the procedure is applied to the lists in
389 (scm_m_sequence_to_list): New syntax: Version of `begin' which
390 returns a list of the results of the body forms instead of the
391 result of the last body form.
392 (scm_definedp, scm_m_undefine): Moved from eval.c
394 * evalext.h (scm_m_sequence_to_list): Added declaration.
396 * macros.c, macros.h: New files.
397 (scm_procedure_to_syntax, scm_procedure_to_macro,
398 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
399 scm_macro_name, scm_macro_transformer): Moved from eval.c
400 (scm_make_synt): Moved from eval.c
402 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
404 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
407 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
409 * debug.c, print.c: Added #include "macros.h".
411 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
413 This change adds the ability to use `unread-char' multiple times
414 without interspersed reads and adds the new procedure
415 `unread-string'. The change is optimized for the common case of
416 unreading a single character. This is also the reason behind the
417 choice to store characters in the port itself: in most cases no
418 extra malloc is required.
420 The amount of code in some macros in ports.h has been increased to
421 the extent that they would fit better as C functions, but, since
422 this code belongs to the port representation, such functions
423 should be placed in ports.c which would cause calls back and forth
424 between ports.c and genio.c. That is not good for performance.
425 Also, keeping them as macros allows the compiler to do some
426 optimizations which are needed to make the current interface
427 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
429 One benchmark (Guile startup time) indicates an increase of
430 loading speed of 1%. Another (reading (using `read') boot-9.scm
431 10 times) shows no change in performance.
433 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
434 made to find a beautiful solution.)
436 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
437 (SCM_TRY_CLRDY): New macro: Only clear the first unread
438 character. (SCM_CLRDY clears all.)
439 (SCM_N_READY_CHARS): New macro: Returns number of unread
440 characters in a port. Returns wrong answer if SCM_CRDYP is false.
441 (struct scm_port_table): New fields: `entry' contains port table
442 index, `cp' points to last unread char, `cbuf' is the buffer for
443 unread chars, `cbufend' points after end of the character buffer.
445 * ports.h, ports.c (scm_unread_string): New procedure.
446 (scm_grow_port_cbuf): New function.
448 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
450 (scm_generic_fgets), fports.c (local_fgets): Use a loop
451 to read unread characters. Use SCM_TRY_CLRDY instead of
454 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
456 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
458 * genio.c, genio.h (scm_ungets): New function.
460 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
463 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
465 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
466 declarations. (Thanks to Russ McManus.)
468 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
470 * numbers.c (num2long): As a software archeologist, I'm proud of
471 this finding! :) Preliminary dating suggests an almost 4 year old
472 remnant from the SCM ancestor. The sample has been removed from
473 the finding site and is now safely stored in the repository.
475 * numbers.h: Removed prototype for num2long.
477 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
479 * gh_data.c (gh_scm2doubles): Make it possible to pass result
481 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
482 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
483 * gh.h: Updated and added prototypes.
485 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
487 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
489 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
491 * guile-snarf.in: Never generate an empty file. (Thanks to
494 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
495 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
496 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
497 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
498 gh_new_procedure5_0): Specify argument types, to appease C++
499 compilers. (Thanks to Brad Bowman.)
501 Bug reports from Russ McManus:
502 * guile-snarf.in: If the CPP environment variable is set, use that
503 as the C preprocessor, instead of the preprocessor autoconf
505 * snarf.h (SCM_PROC): Cast the function pointer passed to
506 scm_make_gsubr, to satisfy C++.
508 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
509 Use the handler passed, instead of ignoring it and using
510 gh_standard_handler. (Thanks to Etienne Bernard.)
512 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
514 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

537 * script.c (scm_compile_shell_switches): Define
538 use-emacs-interface in the root module, so the repl code can see
539 it. See today's change to top-repl in ice-9/boot-9.scm.
541 * filesys.c (set_element, get_element): Make sure that `element'
542 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
543 Boekemeier and Jorgen "forcer" Schaefer.)
545 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
547 * chars.c (scm_charnames): In ASCII character name table, make
548 newlines print as #\newline by default, not #\nl.
550 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
551 alphabetical order. Oh thrills. But it helps me know how far
552 along in the compilation I am.
553 * Makefile.in: Regenerated.
555 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
557 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
558 #bytes(...) to #y(...), and syntax for short vectors from
559 #short(...) to #h(...). This may seem nutty, but, like the other
560 uniform vectors, byte vectors and short vectors want to have the
561 same print and read syntax (and, more basic, want to have read
562 syntax!). Changing the read syntax to use multiple characters
563 after the hash sign breaks with the conventions used in R5RS and
564 the conventions used for the other uniform vectors. It also
565 introduces complexity in the current reader, both on the C and
566 Scheme levels. (The Right solution is probably to change the
567 syntax and prototypes for uniform vectors entirely.)
569 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
571 Don't use local_fgets on sockets; ftell doesn't work on sockets.
572 (Thanks to Jorgen "forcer" Schaefer.)
573 * ports.h (SCM_NOFTELL): New flag.
574 * fports.c (local_fgets): If it's set, use the generic fgets.
575 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
577 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
579 * script.c (scm_compile_shell_switches): Add handling of -q switch
580 (inhibit loading of user init file).
581 (scm_shell_usage): Add usage text for -q switch.
582 (scm_compile_shell_switches): Always load user init file first if
585 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
587 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
588 and is now broken under NetBSD. I can't fathom what it's trying
589 to do, so I've replaced it with something that I do understand,
590 which seems to work, and which isn't broken on NetBSD. "Progress?
591 You Decide." (Thanks to Perry Metzger.)
593 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
594 signed/unsigned comparison.
596 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
598 Warning fixes from Greg Harvey:
599 * unif.c (scm_array_set_x): initializer for pos
600 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
601 * struct.c (scm_struct_ref, scm_struct_set_x): Added
602 initializers for field_type, since EGCS so desparately wants to
604 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
605 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
606 when GUILE_DEBUG is defined.
607 * dynwind.h (scm_wind_chain): Same.
608 * ports.h (scm_pt_size, scm_pt_member): Same.
609 * print.h (scm_current_pstate): Same.
610 * procs.h (scm_make_cclo): Same.
612 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
614 Handle short and long long uniform arrays properly. (Thanks to
616 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
617 raeql_1): Add cases for scm_tc7_svect (short vectors) and
618 scm_tc7_llvect (long long vectors).
620 Change the way libguile and boot-9.scm are timestamped, to try to
621 get rid of these spurious mismatch warnings. Now both
622 libguile/versiondat.h and ice-9/version.scm are generated directly
623 by the configuration process, rather than having version.scm
624 generated directly, and libguile/versiondat.h generated by the
625 Makefile, which is generated by configure. It seems that
626 sometimes the Makefile would change, but versiondat.h depends on
627 Makefile.in, not Makefile, so it wouldn't get rebuilt.
628 * Makefile.am (versiondat.h): Target removed; this is generated
629 directly by the configure script now.
630 (BUILT_SOURCES): Remove versiondat.h.
631 * versiondat.h.in: New file, transformed by the configure script
633 * Makefile.in: Regenerated.
635 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
636 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
637 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
638 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
639 if we want to use them in a header file some day, we can. (Thanks
642 * stime.c (scm_get_internal_real_time): Do the arithmetic using
643 SCM numbers, so we won't have rollover problems; the range of a
644 signed long in milliseconds is about 25 days. (Thanks to Karl
647 Don't redefine sleep and usleep; fix this problem now.
648 * coop.c (sleep, usleep): Remove declarations; we don't use or
649 redefine these any more.
650 (scm_thread_usleep, scm_thread_sleep): New functions which do the
651 job of usleep and sleep in a thread-friendly way. We can use
652 these in the rest of Guile. Define versions for systems both with
654 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
655 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
656 we're just using it, not redefining it, we can use a K&R style
658 (sleep): Declare this, too, if the system hasn't.
659 (scm_sleep, scm_usleep): Use scm_thread_sleep and
660 scm_uthread_sleep if they're available; otherwise, just call the
662 * scmconfig.h.in: Regenerated.
664 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
666 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
668 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
670 * threads.c: Doc fix.
672 The argument type of usleep varies from system to system,
673 as does the return type. We really shouldn't be redefining usleep
674 at all, but I don't have time to clean that up before the 1.3.
675 release. It's on the schedule for afterwards. (Thanks to Julian
677 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
679 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
680 * scmconfig.h: Regenerated.
682 * simpos.c (scm_software_type): Procedure deleted. This isn't the
683 right way to handle system variation. Autoconf's approach is the
685 * simpos.h (scm_software_type): Declaration deleted.
687 * script.c (scm_find_executable): Don't test if unix is #defined
688 here; first, NetBSD doesn't #define it, and second, it's the wrong
689 way to go about these things. (Thanks to Perry Metzger.)
690 (dld_find_executable): Delete this MSDOS support code. This isn't
691 the way we want to support this; it needs to be rethunk at a
694 * genio.c (scm_do_read_line): Don't just politely check that the
695 line was either non-empty or EOF. Abort if it's empty and not
698 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
700 * scmconfig.h.in: Regenerated.
702 * libguile.h: Don't omit the dynamic linking functions. (Thanks
705 * genio.c (scm_do_read_line): Count lines correctly when the file
706 doesn't end in a newline.
708 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
710 * genio.c (scm_do_read_line): Maintain the line count correctly.
711 (Thanks to Harvey J. Stein and Greg Harvey.)
713 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
716 * numbers.c (big2str): Protect t from garbage collection until
717 we're done. (Thanks to Gary Houston.)
719 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
721 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
723 * Makefile.in: Regenerated.
725 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
726 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
729 Do magic to mix reads and writes on stdio FILE-based ports.
730 (Thanks to Christian Lynbech.)
731 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
733 (pre_read, pre_write): New functions.
734 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
735 local_fputs): Call them.
736 (local_fflush): Mark the port as ready for reading and writing.
737 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
738 flags on new port objects. This might not be accurate --- who
739 knows what state the FILE * is in when we get it --- but it won't
740 do extraneous calls to fflush or fseek, so it's no worse than the
741 behavior before this change.
742 * ports.h: Add comment.
744 Centralize the creation of port objects based on stdio FILE * in
745 fports.c; don't just throw them together anywhere.
746 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
747 what the rest of Guile wants. Don't set the revealed count;
748 that's only appropriate for stdin, stdout, stderr.
749 (scm_standard_stream_to_port): This function does set the revealed
751 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
752 not scm_stdio_to_port.
753 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
754 * fports.c (scm_open_file): Same.
755 * posix.c (scm_pipe): Same.
756 * socket.c (scm_sock_fd_to_port): Same.
757 * ioext.c (scm_fdopen): Same.
758 (scm_freopen): Moved from here to...
759 * fports.c (scm_freopen): ... here. This is really something that
760 munges the internals of an fport, so it should go here.
761 * fports.h (scm_stdio_to_port): Adjust prototype.
762 (scm_standard_stream_to_port, scm_freopen): New protoypes.
763 * ioext.h (scm_freopen): Prototype removed.
765 * filesys.c (set_element, get_element): This can work on both pipe
766 and file ports, so use SCM_FPORTP to typecheck, instead of testing
769 * scmconfig.h.in: Regenerated.
771 Change the definition of the functions in scm_ptobfuns so that
772 they get passed the port object, not the port's stream.
773 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
774 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
775 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
776 Pass the port itself to the scm_ptobs function.
777 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
778 scm_generic_fgets): Same.
779 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
780 getc_void_port, fgets_void_port, close_void_port): Just change the
781 argument names; these functions don't really do anything.
782 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
783 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
784 port as an argument, and use SCM_STREAM to get the stdio FILE *.
785 Also, use prototyped definitions, and get rid of the extra
787 (scm_fptob, scm_pipob): We don't need casts here any more.
788 * strports.c (prinstpt): Use prototype declarations.
789 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
790 and use SCM_STREAM to get the string info. Also, use prototyped
791 definitions, and get rid of the extra declarations.
792 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
795 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
796 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
798 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
799 scm_fgets, for consistency.
800 (scm_fptop, scm_pipob): References updated.
802 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
804 Include the source location in error messages for scripts.
805 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
806 stack is still there when we catch the error.
807 * throw.c (handler_message): If we are handling an error with a
808 message, then put together the proper arguments and call
809 scm_display_error, instead of scm_display_error_message. That
810 displays source location, if it can find it.
812 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
814 * gc.c (scm_unprotect_object): Change this so that calls to
815 scm_protect_object and scm_unprotect_object nest properly.
816 (scm_protect_object): Doc fixes.
818 * strings.c (scm_string_set_x): Require the argument to be a
819 writable string, not a substring or a symbol.
820 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
821 (Thanks to John Redford and Charbel Jacquin.)
823 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
825 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
827 * eval.c (safe_setjmp): Remove this misunderstanding.
828 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
831 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
833 * libguile.h: Mark these as C declarations, for compilation by C++
836 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
837 __cplusplus clause. I seriously doubt this ever worked the way
838 the author seems to have intended.
840 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
842 Utterly needless cleanups to hopelessly messy code.
843 * ports.c: Doc fixes.
844 (scm_fflush): Moved to ...
845 * genio.c (scm_fflush): ... here, amongst all the other port
846 method invocation functions.
847 * genio.h, ports.h: The prototype moves too.
849 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
851 * backtrace.c (display_error_body): The current frame does not
852 always have a parent frame; consider a function called directly
853 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
856 * alloca.c (alloca): Undo yesterday's changes, and simply call
857 malloc directly for storage, and abort if we don't get what we
858 want. The situation is much simpler --- just call malloc. Emacs
859 has bizarre/evil requirements (signal handlers might malloc unless
860 you set this global flag, so you have to set the flag around all
861 calls to malloc) which we are certainly not going to conform to,
862 so we can do the simple and obvious thing.
864 * coop.c (coop_condition_variable_wait): Make this function
865 static. It's only useful internally --- you should never just
866 wait on a condition variable.
867 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
869 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
871 * unif.c (scm_array_set_x): Accept any kind of number as an
872 element for a uniform vector of doubles. This is more consistent
873 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
875 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
876 works; I can't conveniently test it myself. (Thanks to Dvid
877 Tillman for the bug report.)
881 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
882 from here, not from scm_compile_shell_switches (which is a pretty
883 dumb place to do it).
884 (scm_load_startup_files): New function.
885 (scm_ice_9_already_loaded): Variable moved to here from script.c.
886 * script.c (scm_compile_shell_switches): Don't load the startup
888 (scm_ice_9_already_loaded): Variable moved.
889 * init.c (scm_load_startup_files): Prototype for new function.
890 * gh_init.c (gh_enter): Doc fix.
892 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
894 Some anti-warning changes from Greg Harvey.
895 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
896 warnings when it doesn't understand our NORETURN declarations in
898 * posix.c (scm_mknod): Similar.
900 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
902 * posix.c (scm_getpwuid): If we can't find an entry, return our
903 own message, instead of using scm_syserror --- the getpwMUMBLE
904 functions don't set `errno' to anything interesting.
906 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
908 Get rid of warnings from the cooperative threading system.
909 * threads.h (scm_single_thread_p, scm_yield,
910 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
911 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
912 scm_wait_condition_variable, scm_signal_condition_variable): Add
913 prototypes for these Scheme-visible functions.
914 * coop-defs.h (coop_next_runnable_thread,
915 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
916 Prototypes for these here, even though they're from iselect.c.
917 (coop_condition_variable_wait, coop_join): Add prototypes.
918 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
919 scm_threads_free_condvar): Make these smob functions static.
920 * coop-threads.h (coop_init): Give this a real prototype.
921 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
922 (coop_next_runnable_thread): No need to provide prototype; it's in
925 * scmconfig.h.in: .detarenegeR
927 * iselect.c, threads.c: Doc fixes.
929 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
931 * Makefile.in: Regenerated with a patched automake, to get
932 dependency generation right when using EGCS.
934 * inet_aton.c (inet_aton): Add prototype, to remove compiler
935 warning. (Thanks to Robert Pluim.)
937 * inet_aton.c (inet_aton): Reassure the compiler that the
938 arguments to the <ctype.h> macros are all unsigned characters, not
941 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
943 Getting rid of more warnings...
944 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
945 today's change to ../configure.in.
946 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
947 * scmconfig.h.in: Regenertaded.de.,.__
948 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
949 (scm_localtime, scm_mktime): Use a const char * to manipulate the
952 * readline.c: Doc fix.
953 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
954 * readline.h (scm_filename_completion_function): Add prototype.
955 (scm_init_readline): Make this into a prototype.
957 * readline.c (scm_filename_completion_function): Use SCM_PROC to
958 declare this, instead of calling scm_make_subr manually.
960 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
962 * readline.h (scm_init_readline): Add prototype for this.
963 (scm_init_readline): Make this a real prototype.
965 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
967 Warning fixes from Maciej Stachowiak:
968 * backtrace.h (scm_display_application, scm_backtrace): Add
970 * debug.c (scm_m_start_stack): Make this function static.
971 * fluids.h (scm_fluid_p): Add prototype.
972 * procprop.c (scm_i_procedure_arity): Make this function static.
973 * regex-posix.c (scm_regexp_error_msg): Make this function static.
974 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
975 * root.h (scm_dynamic_root): Add external prototype.
976 * scmsigs.h (scm_usleep): Add external prototype.
977 * script.h (scm_init_script): Use prototype, not K&R decl.
978 * stacks.h (scm_stack_id): Add external prototype.
979 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
981 1998-09-30 Mark Galassi <rosalia@cygnus.com>
983 * gh.h: took out the definitions of vset and vref, since they are
984 replaced by the proper vector routines that correspond to the R4RS
987 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
989 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
990 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
991 third argument, a C expression that should result in a SCM value,
992 which is used to initialize the variable. Reimplemented
993 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
996 * version.h (scm_libguile_config_stamp): Add prototype.
997 (From Maciej Stachowiak.)
999 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
1001 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
1002 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
1004 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
1006 * print.c (scm_iprin1): Rather than having one i, and using it in
1007 several places, declare a fresh i local to each block where it is
1008 used, and give it a signedness appropriate to its use in each case.
1009 (scm_iprlist): Same.
1011 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
1012 comparison warnings.
1014 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
1015 signed/unsigned clashes.
1017 * posix.h (scm_tmpnam): Added prototype.
1019 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
1020 scm_make_subclass_object): Add external prototypes.
1022 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
1023 comparison is okay here.
1025 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
1027 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
1028 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
1030 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
1033 * load.c (swap_port): Make this function static.
1035 * load.c (scm_search_path): Make max_path_len and max_ext_len
1036 unsigned, since they're compared against string sizes.
1038 * load.c (init_build_info): Make i unsigned.
1040 * ioext.h (scm_read_line): Add prototype.
1042 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
1043 scm_hash_fn_remove_x): Make hash bucket index local variable k
1044 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
1045 accurately as possible.
1047 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
1048 comparisons, and range checking to make sure those casts are
1051 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
1052 signed/unsigned comparisons.
1054 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
1055 avoid signed/unsigned comparisons.
1056 * smob.h (scm_numsmob): Change extern declaration to match.
1058 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
1059 avoid signed/unsigned comparisons.
1060 * ports.h (scm_numptob): Change extern declaration to match.
1061 (scm_current_load_port, scm_set_port_line_x,
1062 scm_set_port_column_x): New prototypes.
1064 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
1065 test code, and it causes warnings.
1067 * gh.h (gh_int2scmb, gh_uniform_vector_length,
1068 gh_uniform_vector_ref): Added prototypes.
1070 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
1071 debugging support unconditionally. That's backtrace.c, stack.c,
1072 debug.c, and srcprop.c.
1073 (EXTRA_libguile_la_SOURCES): Omit those from here.
1074 * Makefile.in: Regenerated.
1076 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1078 * options.c (scm_options): Bugfix: Allow empty list of options!
1080 * debug.c, debug.h (scm_single_step): Removed.
1081 (scm_with_traps): New procedure. This procedure could easily be
1082 written in Scheme but needs to be highly optimized.
1084 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
1086 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
1087 Check SCM_TRAPS_P before trapping.
1089 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
1091 Changes to avoid signed/unsigned comparison warnings.
1092 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
1093 (scm_gc_sweep): Make n and j local to the blocks they're used in,
1094 so they can have appropriate types for each application. Make i
1095 signed. Use initializers in some spots. I'll probably pay for
1097 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
1098 (scm_must_realloc): Make nm unsigned.
1099 (init_heap_seg): Make new_seg_index and n_new_objects signed.
1100 (scm_init_storage): Use prototype-style definition, and make the
1102 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
1103 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
1105 * filesys.c (scm_readlink): Make local vars rv and size ints, to
1106 avoid signed/unsigned comparison warnings, and because the return
1107 value of readlink may be -1. Don't bother casting the third
1108 argument to readlink.
1110 * filesys.c (scm_dirname, scm_basename): Move these to their own
1111 page, at the end of the file.
1112 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
1114 * eval.h (scm_eval_options_interface): Add external prototype for this.
1115 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
1117 * eval.c (scm_lookupcar1): Make this static.
1119 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
1120 Make these prototype declarations, not K&R-style.
1122 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
1123 unsigned comparison warning.
1125 * appinit.c: File removed. It had a single function in it, empty,
1126 whose reason for existence is explained in no documentation or
1127 comment. I think it's there as a default for some Tcl-style
1128 initialization, but Tcl abandoned that approach a while ago.
1129 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
1130 (BUILT_SOURCES): Remove appinit.x.
1131 * Makefile.in: Regenerated.
1133 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
1135 * Makefile.in: Regenerated using the last public version of
1136 automake, not the hacked Cygnus version.
1138 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
1140 Remove Totoro kludge.
1141 * Makefile.in, scmconfig.h.in: Regenerated.
1142 * init.c, readline.c: Don't check if TOTORO is #defined.
1144 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
1146 * Makefile.am: Adjust for new thread configuration system.
1147 (INCLUDES): Include the value of THREAD_CPPFLAGS.
1148 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
1150 (THREAD_LIBS): Definition deleted; automake will generate such
1151 things automatically.
1152 * Makefile.in: Regenerated.
1154 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
1156 Simplify smob and port marking; set the mark bit in the generic
1157 marking code, and make marker routines only responsible for
1158 turning up outgoing pointers.
1159 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
1160 before calling the marking function. Don't call the marking
1161 function if it's zero.
1162 * markers.c (scm_mark0): Just return #f. This function isn't
1163 necessary at all now, but it's harmless to call it. We'll leave
1164 it in so other folks' code doesn't croak at link time.
1165 (scm_markcdr): Don't call SCM_SETGC8MARK.
1166 * async.c (mark_async): Don't call SCM_SETGC8MARK.
1167 * dynl.c (mark_dynl_obj): Same.
1168 * root.c (mark_root): Same.
1169 * srcprop.c (marksrcprops): Same.
1170 * unif.c (markra): Same.
1171 * variable.c (scm_markvar): Same.
1172 * ports.c (scm_markstream): Same.
1173 (void_port_ptob): Specify zero for our marking function.
1174 * debug.c (debugobjsmob): Same.
1175 * dynwind.c (guardsmob): Same.
1176 * filesys.c (dir_smob): Same.
1177 * fluids.c (fluid_smob): Same.
1178 * fports.c (scm_fptob, scm_pipob): Same.
1179 * mallocs.c (mallocsmob): Same.
1180 * regex-posix.c (regex_t_smob): Same.
1181 * smob.c (freecell, flob, bigob): Same.
1182 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
1183 * throw.c (jbsmob, lazy_catch_funs): Same.
1185 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1187 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
1188 scm_copy_tree on code in order not to let memoized code to leak
1189 out. Thus, scm_copy_tree needs to copy vectors as well since
1190 quasiquote can introduce evaluated code also inside vector
1193 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1195 * eval.c (scm_copy_tree): Removed ability to copy vectors.
1197 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
1198 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
1201 * unif.c: Say that ivect and uvect are of type signed and unsigned
1202 long instead of int in commentary so that it correctly describes
1205 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1207 * stime.c: Removed declaration of strptime. (It should be
1208 declared by the system headers. If it turns out that some systems
1209 don't, we'll handle that then.) (Thanks to Greg Troxel.)
1211 * stime.h: Renamed TIMEH --> STIMEH
1213 * backtrace.c (scm_display_error, scm_display_backtrace): In order
1214 to increase portability, don't use structure assignment.
1215 (Thanks to Nicolas Neuss.)
1217 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
1219 (finalize_fd_sets): Added empty statement after last case label.
1220 (Thanks to Nicolas Neuss.)
1222 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
1225 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
1227 * init.c, readline.c: OK, I won't have these readline.x bug
1228 reports anymore. We've had them since April. The current reason
1229 is a completely unintelligible failure of totoro.red-bean.com to
1230 do the test for rl_getc_function in libreadline correctly. This
1231 kludge overrides the test if we're on totoro so that the snapshot
1232 generation process can work.
1234 * readline.c: Define a strdup replacement if not existent on system.
1236 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1238 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
1239 This change makes scm_make_vector R5RS compatible. We cannot keep
1240 the third argument since people want to be able to deduce the form
1241 of the C function call only by looking at R5RS. (At the same time
1242 we have removed some unnecessary complexity!)
1244 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
1245 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
1246 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
1247 argument in call to scm_make_vector.
1249 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1251 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
1252 This macro is useful in applications.
1254 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1256 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
1257 (scm_parse_path, scm_search_path): New Scheme level procedures.
1259 * load.h (scm_internal_parse_path, scm_parse_path,
1260 scm_search_path): Declared.
1262 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1264 * filesys.c (dirname, basename): New procedures.
1266 * init.c (scm_boot_guile_1): Removed condition around
1269 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
1270 new data type (guards) for representation of C level guards and
1271 data on the wind chain.
1272 (scm_internal_dynamic_wind): New function.
1274 * dynwind.h: Declare scm_internal_dynamic_wind.
1276 * root.h (scm_root_state): Added scm_cur_loadp.
1278 * root.c (mark_root): Added comment about cur_loadp.
1280 * load.c: #include "dynwind.h";
1281 (scm_primitive_load): Use scm_inner_dynamic_wind to update
1284 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
1286 * ports.c (current-load-port): New procedure.
1288 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1290 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
1291 not a tty, return #f.
1293 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
1294 to Julian Satchell and Roland Kaufmann.)
1296 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
1297 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
1299 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1301 * debug.h, debug.c (scm_start_stack): New function. Implements
1302 the guts of old scm_m_start_stack.
1304 * debug.c (scm_m_start_stack): Use scm_start_stack.
1306 * init.c (scm_start_stack, scm_restart_stack): Renamed to
1307 start_stack and restart_stack. (These have static scope.)
1309 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1311 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
1312 readline functions to come in release 2.3. (Thanks to Chet
1314 (handle_errors): Use the above functions.
1316 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1318 * readline.c: Improvements for readline support: Handle errors
1319 better; Implement before-read-hook.
1321 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1323 * init.c (scm_boot_guile_1), readline.c: Test for
1324 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
1325 assure that we have version >= 2.1.)
1327 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
1329 * readline.c (scm_readline): Defer interrupts while we're calling
1332 * readline.c (scm_add_history): Bugfix: Do strdup before giving
1333 away the string to add_history.
1334 (completion_function): Do completion for readline. (Thanks to
1336 (scm_filename_completion_function): New procedure: Filename
1338 (current_input_getc): New function. Use this one instead of
1339 standard getc from readline.
1341 * throw.c, throw.h (scm_handle_by_throw): New function: This
1342 handler throws errors to next handler on the dynwind chain.
1344 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
1346 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
1349 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1351 * procprop.c (scm_i_procedure_arity): New function. Returns arity
1353 (scm_procedure_properties): Modified to return arity together with
1355 (scm_procedure_property): Added the read-only property `arity'.
1356 (scm_set_procedure_property_x): It is an error to set the `arity'
1359 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
1360 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
1362 * procprop.h (scm_sym_arity): New symbol.
1364 * objects.c (scm_set_object_procedure_x): New procedure: Use this
1365 to set the dispatch procedure of an operator or entity object.
1367 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
1368 Made procedure slots read-only.
1370 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
1371 scm_tcs_cons_gloc case in zero args switch; Fixed args
1372 construction for operators in scm_tcs_cons_gloc case in two args
1375 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1377 * fluids.c: Removed use of assert.h (in order to avoid
1380 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
1382 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
1384 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
1385 change makes the evaluator safer at the cost of evaluation speed.
1386 It handles the case when the user has added a non-immediate
1387 improper end of the application form, e.g., `(+ 0 . x)'.
1388 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
1389 minimize the extra cost as much as possible. The new code is
1390 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
1391 problem with structs planted directly in the code (e.g. by a
1392 macro). This no longer causes segmentation fault. (Thanks to
1395 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
1396 arg `proc' in order to be able to throw errors; New argument
1399 * Removed extra #include "debug.h"
1401 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
1403 * scmsigs.c: Declare usleep as returning void on some systems.
1404 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
1407 * coop.c (usleep): Return void on some systems.
1409 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1411 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
1413 * coop.c: Changed return type of usleep to int.
1415 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
1416 isn't found in the OS.
1418 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
1419 isn't enabled. (Thought that I had made this change ages ago...)
1421 * iselect.c: Declare bzero if not defined by OS.
1423 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1425 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
1426 condition. (Thanks to John Tobey.)
1428 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
1429 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
1432 * __scm.h: Start the long-term project of moving to POSIX threads.
1433 Phase 1: Classification of all critical sections.
1434 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
1435 for A sections. (See comments in __scm.h for details.)
1437 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
1438 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
1440 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1442 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
1443 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
1444 (libpath.h, versiondat.h): Replaced dependency on Makefile with
1445 dependencies on $(srcdir)/Makefile.in
1446 $(top_builddir)/config.status in order to avoid circularity.
1448 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
1449 from argc if argc was 0 initially.
1451 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
1452 in generation of libpath.h.
1454 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
1456 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
1457 libguile from 2 to 3.
1459 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
1461 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
1463 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
1465 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
1466 scm_set_port_column_x, scm_port_filename,
1467 scm_set_port_filename_x): Removed optional arguments. Added
1468 proper argument checking.
1470 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
1471 stack size in machine words.
1473 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
1474 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
1475 to Ole Myren Röhne.)
1477 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
1479 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
1480 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
1482 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
1485 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
1486 procedure apply: Copy argument lists before pushing them unto the
1487 environment so that the environment won't get mutated due to
1488 manipulation of procedure arguments. This should perhaps be
1489 regarded as a temporary solution until someone finds a more
1490 efficient one. (Thanks to Maciej Stachowiak.)
1492 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
1494 * script.c (scm_compile_shell_switches): Use "guile" as default
1495 zero arg if argc is NULL.
1497 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
1499 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
1500 is zero. (Thanks to Dirk Herrmann.)
1502 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
1504 * ports.c (scm_add_to_port_table): First line is now line 0
1505 (was 1). (Interface changed according to suggestion by Per
1508 * backtrace.c (display_header): Add 1 to line and column numbers
1509 when presenting them to the user.
1511 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
1512 from debug.c --> eval.c
1514 * eval.h, eval.c (scm_eval_options_interface): New options
1516 (SCM_EVAL_STACK): New option: Size of newly created stacks,
1517 i.e. stacks for new threads.
1519 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
1521 * eval.c (unsafe_setjmp): Removed with #if 0.
1523 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
1526 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
1527 to avoid compiler warnings.
1529 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
1531 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
1533 * throw.c (handler_message): Print message on current error port
1534 instead of default error port. (Thanks to Maciej Stachowiak.)
1536 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
1538 * ports.c (scm_add_to_port_table): allocate in units of
1539 struct scm_port_table *, not struct scm_port_table.
1540 * posix.c (scm_close_pipe): remove the port from the port table
1542 Thanks to Rob Engle for both fixes.
1544 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1546 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
1547 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
1549 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1551 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
1553 * backtrace.c (display_error_body, display_backtrace_body),
1554 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
1555 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
1556 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
1557 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
1560 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
1561 don't receive the jmpbuf arg anylonger.
1562 (scm_catch): Don't accept a #f tag.
1563 (scm_throw): Check that key is a symbol.
1564 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
1566 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
1568 * async.c (async_pending): Removed declaration.
1570 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1572 * dynwind.c (scm_wind_chain): New debug function.
1574 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
1575 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1576 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1577 extra layer of functions around the body and handler of a thread.
1578 This extra layer makes sure that the handler is called in the
1579 dynamic context of the surround (= empty dynwind list), but under
1580 the *dynamic root* of the body. We can not use the dynamic root
1581 of the surround since that root belongs to another thread => stack
1582 is not handled correctly. It may seem ugly to use this extra
1583 layer, but the extra cost in terms of execution time is really
1584 negligible compared to the total amount of time required to create
1585 a thread, and it would reduce maintainability to duplicate the
1586 crucial and complicated steps performed by cwdr.
1588 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1589 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1590 get re-enabled. The important effect of this is that interrupts
1591 are blocked during thread switching so that thread data structures
1592 don't risk getting messed up by an unfortunate signal.
1593 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1594 seems to do more aggressive optimization which actually move
1595 instructions around in these macros in a fatal way. Therefore:
1596 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1597 just superstitious...)
1598 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1599 This macro should be used instead of SCM_ASYNC_TICK since the
1600 latter doesn't do context switches any more.
1602 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1603 instead of SCM_ASYNC_TICK.
1605 * coop.c, iselect.c: Since thread switches are now performed with
1606 interrupts masked, we can't use the old mechanism of delivering
1607 signals immediately when they arrive. Signals must instead be
1608 delivered when the asyncs run *after* the end of the critical
1609 section in scm_internal_select. But this also means after context
1610 switch so that the signal will be delivered to a different thread.
1611 To avoid this, I have changed the protocol of
1612 coop_wait_for_runnable_thread and friends so that they are allowed
1613 to return the original thread. So, if a signal arrives during
1614 scm_internal_select, we won't any longer be forced do a context
1615 switch, but can remain in the same thread and deliver the signal
1618 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1619 scm_asyncs_pending and made it global.
1621 * iselect.c: Small fixes.
1623 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1624 coop_condition_variable_init, coop_condition_variable_wait,
1625 coop_condition_variable_signal): Changed return type from `void'
1626 to `int'. This is to adhere closer to the pthreads interface.
1627 This, in turn, is part of an attempt to provide C versions of the
1628 mutex and condition variable primitives which can be part of a
1629 frontend to COOP or pthreads.
1631 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1632 coop_condition_variable_destroy): New functions.
1634 * coop-threads.c (scm_wait_condition_variable): Use
1635 coop_condition_variable_wait_mutex.
1637 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1638 Definitions moved to coop-defs.h.
1640 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1641 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1642 scm_cond_destroy): New C interface to mutecis and cond vars.
1644 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1646 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1648 * iselect.c: Now several threads can wait on the same file
1649 descriptor. The behaviour is compatible with OS select: All
1650 threads waiting for the fd return with the same status.
1652 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1654 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1655 Can spawn a thread from application C code.
1657 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1659 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1660 gh_doubles2scm): New functions.
1662 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1664 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1665 commented-out version of gh_eval_str()
1667 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1669 * socket.c (scm_bind): free soka after use.
1671 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1673 * stime.c (tzvar): new variable.
1674 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1675 avoid memory leaks when allocating.
1677 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1679 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1682 * gc.c, tags.h: Doc fixes.
1684 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1686 * eval.c (macro-eval!): Removed. This function was a design bug.
1687 It allowed memoized code to leak out to the scheme level. Most
1688 things that you could do with `macro-eval!' can be done with
1691 1997-12-20 Tim Pierce <twp@skepsis.com>
1693 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1694 scm_fgets now depends on ftell(3) to know how many bytes were
1697 1997-12-15 Tim Pierce <twp@skepsis.com>
1699 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1700 dealing with strings.
1702 1997-12-13 Tim Pierce <twp@skepsis.com>
1704 Make %read-line more suitable for implementing read-line efficiently.
1705 * ioext.c (scm_read_line): Strip the terminating newline from a
1706 string, and return a cons of the string and its terminator.
1708 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1709 of the string that is read is stored in this memory location.
1710 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1711 * genio.c, genio.h (scm_do_read_line): Update caller.
1712 * ports.h (scm_ptobfuns): Update typedef.
1713 * fports.c (scm_fptob, scm_pipob): Update struct.
1715 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1717 * filesys.c (set_element): Return file descriptor.
1718 (fill_select_type): Return the highest file descriptor.
1719 (scm_select): Tell select about the highest file descriptor. On
1720 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1721 Therefore the extra overhead for calculating the maximum fd seems
1722 to be more than compensated. Is this correct? In any case,
1723 scm_internal_select will be much faster with this info.
1724 (scm_select, fill_select_type, set_element): Don't accept any kind
1725 of object in the file descriptor list or vector.
1727 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1729 * iselect.c (finalize_fd_sets): Bugfix.
1731 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1733 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1734 when using scm_internal_select (since we might switch to another
1737 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1739 * simpos.c (scm_system): always define: use sysmissing if not
1740 available. Check for HAVE_SYSTEM instead of _Windows (does
1741 Windows lack system or does it have an unusable one?).
1742 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1743 Let the argument be optional: if not supplied, call system(NULL).
1745 * ports.c (scm_close_port): relax the type check from OPPORTP to
1746 PORTP; closing a closed port is allowed.
1748 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1750 * fports.c (scm_fgets): Return if the last char in a chunk is
1751 newline. When fgets returns a string whose length is `size-1', it
1752 is ambiguous whether a whole line was retrieved, so we must check
1753 explicitly whether a line terminator is present.
1755 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1757 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1758 before taking the CDR. (Thanks to Harald Meland.)
1760 * filesys.c (scm_stat): Slightly optimized.
1762 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1764 * ports.c (scm_close_port): Make sure the port is open before
1767 * guile-snarf.in: Pass args through to gcc in a way that preserves
1768 whitespace boundaries. (Thanks to Greg Badros.)
1770 1997-12-02 Tim Pierce <twp@skepsis.com>
1772 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1773 statement. (Thanks to Doug Evans for pointing this out.)
1775 1997-12-01 Tim Pierce <twp@skepsis.com>
1777 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1779 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1781 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1782 errno macro expansion of this field name. (errno is a C
1783 preprocessor macro on some systems.)
1785 1997-11-29 Tim Pierce <twp@skepsis.com>
1787 * iselect.c: Doc fix.
1789 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1791 * init.c (scm_start_stack): Removed initialization of
1792 scm_the_last_stack_var.
1794 * backtrace.h: Declare scm_the_last_stack_var.
1796 * backtrace.c: Define scm_the_last_stack_var.
1798 * root.c (mark_root): Don't mark the_last_stack_var.
1800 * root.h (scm_root_state): Removed the_last_stack_var.
1802 * throw.c: Added #include "fluids.h"
1803 (ss_handler): `the-last-stack' is now a fluid.
1805 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1806 --> the_last_stack_fluid.
1808 * backtrace.c: Added #include "fluids.h"
1809 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1810 (scm_backtrace): `the-last-stack' is now a fluid.
1812 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1813 after scm_init_fluids.
1815 1997-11-28 Tim Pierce <twp@skepsis.com>
1817 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1819 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1820 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1822 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1824 * iselect.c (coop_next_runnable_thread,
1825 coop_wait_for_runnable_thread): Disable interrupts so that no
1826 async is executed before a potential error_revive.
1827 (scm_internal_select): Disable interrupts during the parts of the
1828 code which manipulate the sleep queue and the file descriptors.
1830 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1832 * Makefile.am: Added iselect.c and iselect.h.
1834 * coop.c (coop_qinit): Initialize fields used by
1835 scm_internal_select.
1836 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1837 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1838 replacement in iselect.c.
1839 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1840 coop_join): If GUILE_ISELECT enabled, use
1841 coop_wait_for_runnable_thread instead of
1842 coop_next_runnable_thread.
1843 (usleep, sleep): New replacements for system functions if
1844 GUILE_ISELECT is enabled.
1846 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1848 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1850 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1851 iselect.h. Implement Scheme level `select' using
1852 scm_internal_select. (See NEWS.)
1854 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1856 * init.c: Call scm_init_iselect.
1858 * iselect.h, iselect.c: New files. Implements
1859 scm_internal_select. (See NEWS.)
1861 1997-11-27 Tim Pierce <twp@skepsis.com>
1863 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1864 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1865 and scm_must_free, since ultimately the string returned will be copied
1866 by scm_makfrom0str anyway. Also, read any characters that may have
1867 been pushed onto the port with scm_ungetc.
1868 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1869 * ioext.c (scm_read_line): Free string after Guilifying it.
1870 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
1872 1997-11-26 Anthony Green <green@hoser.cygnus.com>
1874 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1876 * gh.h: Safely wrap prototypes for c++ usage.
1878 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1880 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1881 gh_repl (argc, argv).
1883 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1885 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1886 and to invoke scm_shell().
1887 (gh_launch_pad): took out the loading of boot-9.scm from here,
1888 since it is probably best to let the user control that. In fact,
1889 gh_repl() now invokes scm_shell() which does that.
1891 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1893 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
1896 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
1898 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
1899 yesterday's underscore patch. (Thanks to Marius Vollmer for
1902 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
1904 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
1905 DLSYM_ADDS_USCORE is not defined.
1907 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
1909 * gh_data.c (gh_uniform_vector_length):
1910 (gh_uniform_vector_ref): started implementing the uniform types in
1913 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1915 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1916 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1918 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1920 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1921 configure.in was changed).
1923 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1925 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1926 * Makefile.in: Regenerated.
1928 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1930 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1931 OPORT is an `open' port, not an output port.
1933 * filesys.c (scm_close, set_element, get_element, scm_chown,
1934 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
1935 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
1936 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
1937 scm_close_port, scm_port_line, scm_set_port_line_x,
1938 scm_port_column, scm_set_port_column_x, scm_port_filename,
1939 scm_set_port_filename_x, scm_port_mode,
1940 scm_close_all_ports_except, scm_set_current_output_port,
1941 scm_set_current_error_port): Likewise
1942 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1943 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1945 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1946 * backtrace.c (display_backtrace_body): Likewise
1947 * fports (scm_setvbuf): Likewise
1948 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
1949 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
1950 scm_getpeername, scm_send, scm_sendto): Likewise
1951 * unif.c (scm_uniform_array_write): Likewise
1953 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1955 Minor problems with substring-related tag changes.
1956 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1957 exactly what we want to leave in to detect substrings.
1958 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1959 * tags.h: Fix diagrams and comments describing the S tag bit;
1960 remove vestigial remarks about the D tag bit.
1961 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1962 * strings.c: Formatting tweaks.
1964 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1965 variable first; then SCHEME_LOAD_PATH, with a warning message.
1966 (scm_parse_path): New function.
1967 * script.c: Doc fixes.
1969 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1971 Readline support, from Daniel Risacher.
1972 * readline.c, readline.h: New files.
1973 * init.c: #include "readline.h".
1974 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1975 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1976 * Makefile.in: Regenerated.
1977 * scmconfig.h.in: Regenerated, after change to ../configure.
1979 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1981 * gh.h: gh_vector_set -> gh_vector_set_x
1983 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1985 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1986 with the ! -> _x mapping when going from Scheme to C.
1988 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1990 * gh.h (gh_reverse):
1998 (gh_assoc): added these gh_ functions implemented as macros.
2000 * gh_predicates.c (gh_null_p):
2001 (gh_string_equal_p): added these two missing predicates.
2003 * gh_list.c (gh_append):
2008 (gh_set_cdr_x): added these routines as I go through and try to
2009 complete the picture R4RS functions that should be mirrored in the
2012 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2014 * tags.h (scm_tc7_substring): Changed the comment and code to
2015 conform with the changes below. Folks! We have suddenly two new
2016 free tc7 codes!!! Jummy, jummy!
2018 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
2020 * Makefile.in: Rebuilt.
2021 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
2023 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
2024 * unif.c (scm_vector_set_length_x): Don't handle multibyte
2026 * tag.c (scm_utag_mb_string, scm_utag_mb_substring): Removed.
2027 (scm_tag): Don't handle multibyte strings.
2028 * read.c: Don't include mbstrings.h.
2029 (scm_lreadr): Don't handle multibyte ports.
2030 * kw.c: Don't include mbstrings.h.
2031 * init.c: Don't include mbstrings.h.
2032 (scm_boot_guile_1): Don't init mbstrings module.
2033 * hash.c (scm_hasher): Don't handle mbstrings.
2034 * gscm.c (gscm_run_scm): Don't init mbstrings module.
2035 * gc.c (scm_gc_mark): Don't handle mbstrings.
2036 (scm_gc_sweep): Likewise.
2037 * eval.c (SCM_CEVAL): Don't handle mbstrings.
2038 * eq.c (scm_equal_p): Use SCM_TYP7S, not SCM_TYP7SD.
2039 * tags.h (SCM_TYP7SD): Removed.
2040 (SCM_TYP7D): Removed.
2041 (scm_tc7_mb_string): Removed.
2042 (scm_tc7_mb_substring): Removed.
2043 * print.c (scm_iprin1): Handle char printing directly. Don't
2045 Don't include "mbstrings.h".
2046 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
2047 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
2049 Don't include "mbstrings.h".
2050 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
2051 (SCM_SYMBOL_SLOTS): Define as 4.
2052 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
2053 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
2054 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
2055 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
2056 struct.c, threads.c, throw.c, unif.c, variable.c: Use new
2057 ("gen"-less) I/O function names.
2058 * ports.c (scm_add_to_port_table): Don't set port's
2060 * ports.h (scm_port_representation_type): Removed.
2061 (scm_string_representation_type): Removed.
2062 (struct scm_port_table ): Removed representation field.
2063 (SCM_PORT_REPRESENTATION): Removed.
2064 (SCM_SET_PORT_REPRESENTATION): Removed.
2065 * genio.h: Use new function names.
2066 * genio.c: Don't include "extchrs.h".
2067 (scm_gen_putc, scm_gen_puts, scm_gen_write, scm_get_getc):
2069 (scm_putc, scm_puts, scm_lfwrite): No longer static.
2070 (scm_getc): No longer static; handle line and column changes.
2071 (scm_ungetc): Renamed from scm_gen_ungetc.
2072 (scm_do_read_line): Renamed from scm_gen_read_line.
2073 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
2074 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
2076 1997-10-12 Mark Galassi <rosalia@cygnus.com>
2078 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
2080 * gh_test_c.c (c_vector_test): some improvements on the vector
2083 * gh.h (gh_vector): this used to exist but do the wrong thing.
2084 Now it (almost) does the right thing, though it takes a list
2085 instead of the individual arguments. I need to see how it could
2087 (gh_list_to_vector): added this function as a macro. Corresponds
2088 to Scheme's (list->vector ...).
2089 (gh_vector_to_list): added this function as a macro. Corresponds
2090 to Scheme's (vector->list ...).
2092 * gh_data.c (gh_vector_ref): renamed from gh_vref to
2093 gh_vector_ref, so that it resembles the Scheme routines more.
2094 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
2095 resembles the Scheme routines more.
2096 (gh_make_vector): this used to be (stupidly) called gh_vector().
2097 This is the right name, since it does the same thing as the Scheme
2098 (make-vector ...) procedure.
2100 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
2102 * ports.h: #include "libguile/print.h"
2104 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
2105 Some indentation fixes.
2107 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
2108 longer a user field; New field: class_flags.
2110 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
2112 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
2114 * gh_data.c (gh_bool2scm): new function which replaces
2115 gh_int2scmb(), which is now tagged as obsolete.
2117 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
2119 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
2120 macros should by convention not test for NIMPness.)
2121 (SCM_COERCE_OPORT): Adjust indentation.
2123 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
2124 SCM_NIMP test before SCM_PRINT_STATE_P.
2126 * struct.c, struct.h, gc.c: Renamed:
2127 scm_struct_i_layout --> scm_vtable_index_layout
2128 scm_struct_i_vcell --> scm_vtable_index_vcell
2129 scm_struct_i_vtable --> scm_vtable_index_vtable
2130 scm_struct_i_printer --> scm_vtable_index_printer
2131 scm_struct_i_vtable_offset --> scm_vtable_offset_user
2133 * struct.c (scm_print_struct): Use new printer slot; Default
2134 printing: Also output hex code of vtable so that type identity
2135 will be indicated as well.
2136 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
2137 Removed struct_printer_var; Removed struct-vtable-offset;
2138 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
2139 vtable-offset-user): New constants.
2141 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
2142 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
2143 If this slot contains a procedure, use that to print structures of
2144 the type represented by this vtable.
2146 * print.c (scm_iprin1): Don't print arguments of macro
2147 transformers. (They are always: exp env.); Bugfix: Unmemoize
2148 transformer source with correct environment.
2150 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
2152 Streamlining of call-with-dynamic-root:
2154 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
2155 there is now only one catch.
2156 (cwdr_outer_body): Removed.
2157 (cwdr_handler): New function.
2158 (scm_internal_cwdr): New function to perform the function of cwdr
2159 but take args that are more useful to C code. Also, the handler
2160 is now invoked *outside* of the new dynamic root, like the docs
2161 say. We no longer have to catch absolutely all errors, the caller
2162 is responsible for using a handler that does not throw, if he
2164 (cwdr): Reimplemented in terms of scm_internal_cwdr.
2165 * root.h (scm_internal_cwdr): New prototype.
2167 Even more but risky streamlining:
2169 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
2170 allocation of the jumpbuf of a root continuation. The changes
2171 below are controlled by it. They are now deactivated.
2172 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
2173 the JMPBUF of the scm_rootcont to NULL before returning.
2175 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
2176 when they are non-NULL.
2177 (scm_gc_mark): Likewise, mark only when non-NULL.
2179 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
2180 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
2182 * gc.c (scm_done_malloc): New function.
2183 gc.h (scm_done_malloc): New prototype.
2185 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
2186 (struct scm_print_state) [revealed]: New field.
2187 (scm_print_state_vtable): Make visible to the outside world for
2188 type checking purposes.
2189 (scm_valid_oport_value_p): New prototype.
2191 * print.c (scm_valid_oport_value_p): New function to check whether
2192 a certain value is acceptable as a port argument.
2193 (scm_print_state_vtable): New variable.
2194 (scm_free_print_state): Set `revealed' field to false.
2195 (scm_iprin1): Call user supplied closure printer with
2196 scm_printer_apply. Print in the traditional way when there isn't
2197 one or when it returns #f.
2198 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
2199 Accept a port/print-state pair in addition to just a port.
2200 (scm_prin1): Don't return the print_state to the pool when it has
2202 (scm_printer_apply): Set `revealed' field of print_state to true.
2203 (scm_init_print): Set scm_print_state_vtable.
2204 (print_state_fluid, print_state_fluid_num): Removed.
2206 * throw.h (scm_handle_by_proc_catching_all): New prototype
2207 throw.c (scm_handle_by_proc_catching_all): New function
2209 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
2211 * Makefile.in: Regenerated with automake 1.2c.
2213 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
2215 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
2216 was looping endlessly.
2218 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
2220 * strports.c (scm_eval_string): Don't close the port.
2222 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
2223 former returns a nice normal integer. (Thanks to Daniel
2226 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
2228 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
2229 makefile variable as a build parameter called LIBS. The
2230 build-guile program will use this, for the time being.
2231 * Makefile.in: Regenerated.
2233 Thanks to Shiro Kawai:
2234 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
2235 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
2238 * Makefile.in: Regenerated with automake 1.2a.
2240 * script.c (scm_compile_shell_switches): If we hit the -c or --
2241 arguments, don't set the car of (command-line) to scm_usage_name,
2242 the prettified name of the guile executable; give it the full
2243 path, the way shells usually handle $0.
2245 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2247 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
2248 Scheme-level name `array-map' and renamed `serial-array-map' to
2249 `serial-array-map!'.
2251 * backtrace.c: Introduced exception handlers which now enclose
2252 `display-error' and `display-backtrace' so that error reporting
2253 won't get into infinite loops if an error occurs during displaying
2254 of the error. This can very easily happen with user supplied
2255 print call-back routines.
2257 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2259 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
2260 the names `serial-array-map' and `array-map' should be removed.)
2262 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
2264 * init.c (scm_boot_guile_1): Added scm_init_objects ().
2265 Added #include "objects.h"
2267 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
2268 Add #include "feature.h".
2270 * Makefile.am (libguile_la_SOURCES): Added objects.c.
2271 (modinclude_HEADERS): Added objects.h.
2273 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
2274 This test is needed at many places in the code and should be
2275 abstracted. (Motivated by the need of this test in libguiletk.)
2277 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
2278 (scm_eval_string), load.c (scm_primitive_load,
2279 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
2280 Use SCM_EOF_OBJECT_P.
2282 * eval.c (scm_init_eval): Add feature `delay'.
2284 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2286 * scmhob.h: Removed.
2288 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2290 * list.h (SCM_LISTn): New macros. Make list creation in C code
2291 prettier. The idea comes from STk.
2293 * sequences.h, sequences.c, append.h, append.c: Removed. These
2294 files implemented non-R4RS operations which would encourage
2295 non-portable programming style and less easy-to-read code.
2297 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
2300 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
2301 sequences.h, #include append.h.
2303 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
2306 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
2308 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
2310 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
2312 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2314 * eval.c: Added #include "objects.h"
2316 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
2319 * smob.c (scm_smob_prehistory): Create two objectsmobs with
2320 adjacent smob numbers.
2322 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2324 * procprop.h: Added declaration of scm_i_inner_name.
2326 * gsubr.c: New global symbol scm_i_inner_name.
2328 * debug.c (scm_procedure_name): Try procedure property
2329 `inner-name' if `name' fails.
2331 * print.c (scm_iprin1): Use scm_macro_name.
2333 * eval.c (scm_m_define): Give names to macros as well; Only the
2334 first top-level definition gives a procedure/macro a name.
2335 Otherwise confusing names can turn up in backtraces.
2336 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
2337 `name'; Give names to macros as well.
2339 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
2340 (scm_macro_transformer): Use SCM_CLOSUREP instead of
2343 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2345 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
2347 (prinmacro): Removed. The code has been moved/merged into print.c
2348 in order to decrease code redundancy. We want macros to print in
2349 a way equivalent to procedures, and it would be silly to duplicate
2350 the required code. (We don't want to maintain two places.)
2351 (macrosmob): Print field is now a NULL pointer.
2353 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
2354 scm_macro_transformer): New prototypes.
2355 (scm_tc16_macro): Declared.
2357 * print.c (scm_iprin1): Added code for printing of macros. Macros
2358 are now printed in a way equivalent to procedures.
2360 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
2362 * procs.h (scm_closure_p): Added declaration.
2364 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2366 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
2367 Shouldn't pass "heap" as the subr name.
2369 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
2371 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
2372 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
2373 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
2374 gh_equal_p): Use SCM_NFALSEP, instead of testing against
2375 SCM_BOOL_T. Any non-false value is true.
2377 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2379 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
2380 scm_gensym): Added prototypes.
2382 * symbols.c (scm_gensym): New function. This will speed up
2383 certain types of applications (such as macro systems) which
2384 generate lots of symbols.
2386 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2388 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
2390 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
2392 * unif.c (scm_shap2ra): tighten the checking of the array dimension
2393 specifier, since (2) or (2 . 3) would cause SEGV.
2394 (scm_transpose_array): more argument checking fixes.
2396 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
2398 * Makefile.in: Regenerated.
2400 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
2402 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
2404 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2406 * error.c, error.h (scm_error_callback): Removed (see NEWS).
2408 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
2410 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
2411 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
2414 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
2415 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
2416 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
2417 scm_array_p, scm_array_rank, scm_array_dimensions,
2418 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
2419 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
2420 scm_array_prototype): Added case scm_tc7_wvect.
2422 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
2424 * errno.h: prototype for scm_strerror.
2425 * error.c (scm_strerror): new procedure.
2427 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2429 * list.c (scm_list_append_x): Allow non-pair as last argument.
2430 This is consistent with the R4RS append and is probably the
2431 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
2433 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2435 * stime.h: prototype for scm_times.
2436 * stime.c (scm_times): new procedure.
2437 * ioext.c (scm_fseek): if the first argument is a file descriptor
2439 (scm_ftell): if the first argument is a file descriptor call lseek
2441 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
2442 * filesys.c (scm_chmod): if the first argument is a file descriptor,
2444 (scm_chown): if the first argument is a port or file descriptor,
2446 (scm_truncate_file): new procedure.
2447 Add DEFER/ALLOW INTS to a few other procedures.
2448 (scm_fsync): new procedure.
2449 (scm_open_fdes): new procedure.
2450 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
2452 (scm_fcntl): the first argument can now be a file descriptor. The
2453 third argument is now optional.
2455 * posix.c (scm_execl, scm_execlp): make the filename argument
2456 compulsory, since omitting it causes SEGV.
2457 (scm_sync): return unspecified instead of #f.
2458 (scm_execle): new procedure.
2459 (environ_list_to_c): new procedure.
2460 (scm_environ): use environ_list_to_c. disable interrupts.
2461 (scm_convert_exec_args): take pos and subr arguments and
2462 improve error checking.
2464 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2466 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
2467 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
2468 argument to SCM_ASSERT. Furthermore, the name of the function
2469 should be passed as first argument when signalling
2470 SCM_WNA. (Thanks to Thomas Morgan)
2472 * gsubr.c (scm_gsubr_apply): From Radey Shouman
2473 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
2474 dispatches on the number of actual args has a default case
2475 reporting an internal error. This is a vestige from a version
2476 that mallocated a SCM vector to hold the arguments. In the
2477 current version this check is too late: if it ever happens we will
2478 have already overstepped the bounds of the array.
2480 Also, the patch [...] adds a check for too many actual arguments."
2482 mdj: Removed check for "internal programming error".
2484 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2486 * gh_io.c (gh_write): New function.
2488 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
2489 throw.c (scm_internal_stack_catch): New sibling to the other catch
2490 functions. Code moved from gh_eval.c.
2491 throw.h: Added header.

2633 but that should be much less likely.

2678 DEBUG_EXTENSIONS isn't #defined.

2707 have to do this explicitly. Also, if regexp/basic is supplied, then
2708 turn off REG_EXTENDED.
2709 (scm_init_regex_posix): New regexp/basic symbol.
2710 (REG_BASIC): #define this if it is not already present.

2757 (cwdr_outer_body): New function, to establish the user's handler,
2758 and pass control to cwdr_inner_body.

2768 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2769 across this. Only works on GCC. Otherwise, we hope for the best.
2770 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2771 the feeling that real thread systems will not need this...
2773 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2775 Try to detect when people are using one version of libguile and a

2787 primitive definitions under their Scheme names.
2789 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2790 1:2. Helps avoid confusion between installed and uninstalled libs.
2792 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2795 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2796 backslash from definition; this should be used like: GDB_INTERFACE;
2798 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2800 * ioext.c (scm_duplicate_port): bug fix: don't try to make the

2805 * ports.h: new prototype.

2815 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2817 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA

2821 * tag.c (scm_tag): Remove unreachable statement.
2822 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2823 top of the word, it should be unsigned.
2825 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2826 is defined, to avoid warnings; it's only used in the
2827 conflict-checking code. Which might go away anyway.
2828 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2829 conditionals; put the label definition in an #if too, to stifle
2832 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2833 ChangeLog-threads in the distribution.
2834 * Makefile.in: Regenerated.

2844 * load.c (scm_init_load_path): Append $(datadir)/guile to

2875 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2876 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2879 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2881 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2882 supplied. (Change from Tim Pierce.)
2884 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2886 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2887 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2888 default and not `()'. `#f' is the canonical non-value in Scheme,
2891 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2893 * struct.c (struct_printer): New variable that holds a handle on
2894 the Scheme variable *struct-printer*. This variable can be set by
2895 Scheme code to override the printing of structures.
2896 (scm_print_struct): If struct_printer is set, call it. If it is
2897 not set, or returns #f, print the structure in the old fashion.
2898 Include "eval.h" for scm_apply.
2900 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2902 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2903 scm_struct_i_n_words to get the number of fields, not
2904 -scm_struct_n_extra_words.
2906 On the route to fancier struct printing:
2907 * struct.c (scm_print_struct): New function to print a structure.
2908 Include "genio.h" to support it. This function doesn't do
2909 anything interesting right now, but I think it should be here
2911 * struct.h: Include "print.h" and add prototype for
2913 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2914 print structures ourself.
2916 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2918 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2919 before applying the handler in case it doesn't return.
2921 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>

2925 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2928 * posix.c (scm_uname): interpret only negative values as an error.
2929 Solaris normally returns a positive value.
2931 * script.c (scm_compile_shell_switches): if we are not going into
2932 an interactive repl, set scm_mask_ints to zero so that asyncs can
2935 * simpos.c (scm_system): don't ignore/unignore signals around
2938 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2941 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2942 done in boot-9.scm instead.
2944 * scmsigs.c, async.c: Major rewriting of signal handling code.
2945 (scm_sigaction): new procedure.
2946 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2948 (scm_raise): return unspecified, throw error on failure.
2950 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2952 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2953 feature, to help boot-9.scm decide whether to import the regex
2956 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2958 * eval.c: Include scmconfig.h at the beginning of the file so that
2959 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2962 * regex-posix.c: #include "_scm.h" before conditionally #including
2963 <regex.h>; the former defines HAVE_REGCOMP.
2965 * regex-posix.c: #include <regex.h> conditionally, so the file is
2966 CPP'able (for dependency scanning) even on systems that don't have
2969 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2971 Add new R4RS-compliant syntax for keywords.
2972 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2973 regardless of the setting of the `keywords' read option.
2974 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2975 can be re-read no matter what the setting of the `keywords' read
2978 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2980 Add support for POSIX regular expressions.
2982 * regex-posix.c, regex-posix.h: New files. (Some code
2983 is taken liberally from rx/rgx.c in the old Guile dist.)
2985 * init.c: Include regex-posix.h.
2986 (scm_boot_guile_1): Call scm_init_regex_posix.
2988 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2989 Add regex-posix.[ch] sources.
2990 * Makefile.in: Regenerated.
2992 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2993 to do this automatically? It didn't for me, bleh.)
2995 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2997 * fports.c (print_pipe_port): New function.
2998 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2999 latter doesn't even take the right arguments.
3001 * Makefile.am: Increment shared lib revision number. I think
3002 sometimes the uninstalled Guile finds the installed shared lib;
3003 Gord says doing this might help. As things turned out, I can't
3004 say whether it does.
3005 * Makefile.in: Regenerated.
3007 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
3008 passing it as the closure argument to scm_boot_guile. (Bill
3011 * ports.c (print_void_port, putc_void_port, puts_void_port,
3012 write_void_port, flush_void_port, getc_void_port, close_void_port,
3013 noop0): Use ANSI prototypes instead of K&R declarations, so the
3014 initialization of void_port_ptob gets aggressively type-checked.
3015 Fix arguments of print_void_port and write_void_port. (Bill

3049 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
3051 * script.c (scm_find_executable): Use prototype-style definition
3052 here; apparently it's not quite right to have const in a prototype
3053 and then use a K&R declaration. I wonder if stuff like this will
3054 go away if we compile with -Wrequire-prototypes, or whatever that
3055 is... (Bernard URBAN)
3057 * scmhob.h: New text from Bernard URBAN.
3059 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
3061 * script.c: Don't #define const on hpux. Configure takes care of
3062 this. (Thanks to Larry Schwimmer.)
3064 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
3065 decide whether to #include <unistd.h>, instead of listing a bunch
3066 of systems. Don't #include stdio twice. Removed dyked-out
3067 definition of scm_find_impl_file.
3069 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
3071 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
3072 library version info to 1:0.
3073 * Makefile.in: Regenerated.
3075 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

3079 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
3080 throw.c: Update copyright years; these files have been worked on
3081 significantly in 1997, but only had copyright years for 1996.
3082 Also, change name of copyright holder on some from Mikael
3083 Djurfeldt to Free Software Foundation; he has signed papers
3084 assigning the changes to the FSF.
3086 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
3087 reason not to give the user the option.
3089 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3090 Return #f on end-of-file when scanning table (i.e. when called
3091 with no arguments). Try to catch errors, when we can.
3092 * posix.c (scm_getgrgid, scm_getpwuid): Same.
3094 * script.h (scm_shell_usage, scm_compile_shell_switches): New
3095 external declarations. These are useful.
3097 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
3099 * posix.c: don't include <sys/select.h> or define macros for
3100 select, since they were not used in this file.
3102 * filesys.c (scm_select): make the fifth parameter microseconds,
3103 not milliseconds. let the fourth parameter be either a real value
3104 or an integer or #f. The first, second and third arguments can
3105 now be vectors: the type of the corresponding return set will be
3107 (set_element, get_element): new static procedures.
3109 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
3111 * strports.c (scm_eval_string): New function.
3112 (scm_eval_0str): Trivially re-implemented in terms of
3114 * strports.h (scm_eval_string): New extern decl.
3116 * net_db.c (h_errno): Add extern decl for this.
3118 * fports.c (local_pclose): New function.
3119 (scm_pipob): Use it in the initializer here.
3122 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
3123 Use a meaningful error message when signalling an error. For
3124 this, scm_gethost must check h_errno rather than errno.
3126 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
3128 * Makefile.in: Regenerated, using automake-1.1p.
3130 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
3132 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
3133 not SCM_UNSPECIFIED.
3135 * script.c (scm_compile_shell_switches): don't append (quit) if
3137 (scm_shell): call scm_exit_status and exit on the result of the
3140 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
3142 Ensure that shared substrings are handled properly when passed to
3143 a system call or other foreign function. Many thanks to Tim
3145 * symbols.h (SCM_COERCE_SUBSTR): new macro.
3146 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
3147 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
3148 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
3149 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
3150 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
3151 (scm_display_error_message): use RO macros when strings may be RO.
3152 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
3153 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
3154 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
3155 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
3156 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
3157 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
3158 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
3159 scm_strftime), vports.c (scm_make_soft_port): use
3160 SCM_COERCE_SUBSTR to make sure shared substrings are
3163 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
3165 * error.c (scm_error): Add newline to error message.
3167 * init.c (scm_init_standard_ports): Doc fix.
3169 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
3171 * dynl-shl.c: Completely replaced with new code from Bernard
3174 * script.c (scm_ice_9_already_loaded): New variable.
3175 (scm_compile_shell_switches): Use it.
3177 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3179 * filesys.c (scm_input_waiting_p): add missing third argument to
3182 * stime.c (scm_localtime): copy the result of localtime before
3183 calling gmtime in case they share a buffer.
3184 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
3187 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3189 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
3191 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
3193 * Makefile.am (check-local): New target, which causes 'make check'
3194 to run gh_test_c and gh_test_repl, with some trivial input.
3195 * Makefile.in: Rgnrtd.
3197 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
3199 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
3202 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
3204 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
3205 sure how this was supposed to work.
3206 (scm_async_click): don't send SCM_TICK_SIGNAL.
3207 (scm_init_async): don't initialize %tick-thunk.
3209 * the following change doesn't affect the Scheme interface:
3210 gc-thunk is called at the end of garbage collection. however it's
3211 no longer implemented by pretending it's a signal.
3213 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
3214 system async corresponding to scm_gc_thunk.
3215 * async.h: declare scm_gc_async.
3216 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
3217 gc-thunk directly, instead of going through a signal handler.
3218 (scm_gc_async): new variable, points to the GC system-async.
3219 (scm_init_async): save the GC async as scm_gc_async instead
3220 of using system_signal_asyncs.
3221 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
3223 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
3225 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
3226 Don't screw up if we're interrupted.
3227 * Makefile.in: Regeneradet.
3229 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
3231 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
3233 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
3234 we're not using AM_INIT_GUILE_MODULE any more.
3235 * Makefile.in: Reneregated.
3237 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
3239 Functions for finding variable bindings, grace à Tim Pierce.
3240 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
3241 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
3243 Get 'make dist' to work again.
3244 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
3245 * Makefile.in: Regenerated, like a surry without a fringe on top.
3247 Changes for reduced Guile distribution: one configure script,
3249 * configure.in, configure: Removed.
3250 * acconfig.h, acinclude.m4: Moved to parent directory, where the
3251 real configure script lives.
3252 * Makefile.in, scmconfig.h.in: Regenerated.
3254 * init.c: #include "script.h", to get prototype for script.c's
3257 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
3259 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
3260 scm_must_malloc, not raw malloc.
3262 * script.c (scm_compile_shell_switches): Dyke out debugging output
3265 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3267 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
3269 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
3270 system has them. Hope this is safe. Previously
3271 sys/timeb.h was included if HAVE_FTIME was defined or if
3272 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
3273 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
3275 * ioext.c (scm_setfileno): add missing third argument to
3276 scm_misc_error call.
3278 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
3280 * eq.c (scm_equal_p): Correctly compare strings of different
3281 varieties. (Thanks to Tim Pierce.)
3283 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
3285 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
3286 #! block comment must occur on a line all by itself.
3288 Move most of the guts of shell command processing into libguile,
3289 so guile.c can be very small (and eventuallly auto-generated. (I
3290 mean, generated mechanically, not self-generated. Hmm.))
3291 * guile.c, script.c, script.h: New source files.
3292 * init.c (scm_boot_guile_1): Call scm_init_script.
3293 * libguile.h: #include "script.h".
3294 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
3295 targets, for new executable.
3296 (libguile_la_SOURCES): Mention script.c.
3297 (modinclude_HEADERS): Add script.h.
3298 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
3299 not dynamic linking is enabled. This is because we're generating
3300 executables now. Move CY_AC_WITH_THREADS call after those, so the
3301 values of cy_cv_threads_libs captures the libs chosen above.
3302 * Makefile.in, configure, aclocal.m4: Regenerated.
3304 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
3305 We don't maintain this interface any more, and it just confuses
3308 * alloca.c: #include <scmconfig.h>, not <config.h>.
3309 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
3310 it'll get included in disties.
3312 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
3314 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
3315 be distributed, because they confuse people.
3316 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
3318 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
3320 * configure.in: check for presence of gethostent (not present on
3321 OpenBSD by default).
3322 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
3323 * configure, scmconfig.h.in: Regenerated.
3325 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
3327 * backtrace.c (scm_backtrace): Split message string across
3328 newlines properly. GCC is more tolerant of this than other
3331 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
3333 Merge threads directory into libguile.
3334 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
3335 threads.h: New source files.
3336 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
3337 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
3339 (modinclude_HEADERS): Add threads.h, coop-defs.h.
3340 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3341 coop-threads.c.cygnus, coop-threads.h.cygnus.
3342 * configure.in: If we're using threads, include threads.o in
3344 * _scm.h, libguile.h: threads.h lives in this directory now.
3345 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3346 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
3347 currently used, but brought along for information's sake.
3348 * ChangeLog-threads: log from old 'threads' directory.
3349 * Makefile.in, configure: Rebuilt.
3351 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
3353 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
3356 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
3358 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
3360 Merge GH interface library into libguile.
3361 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
3362 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
3363 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
3364 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
3366 (EXTRA_libguile_la_SOURCES): ... here.
3367 (pkginclude_HEADERS): Add variable, to get gh.h installed.
3368 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
3369 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
3370 New variables, describing how to build the gh test programs.
3371 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
3372 build the test programs, and we probably should have been linking
3373 libguile.la against them all along, to support AIX shared libs.
3374 Add cflags for threads to CFLAGS; add libs for threads to new
3375 variable THREAD_LIBS, used in Makefile.am.
3376 * ChangeLog-gh: log from old `gh' subdirectory.
3377 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
3379 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
3381 * acconfig.h: Undo change of Apr 9; including the definition of
3382 PACKAGE in the guile headers conflicts with applications' own
3384 * scmconfig.h.in: Regenerated.
3386 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
3388 * filesys.c (scm_fcntl): New function from Roland McGrath.
3389 (scm_init_filesys): New symbols for use with fcntl.
3390 * filesys.h: Added prototype.
3392 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
3393 when PROC is receiving no arguments.
3395 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
3397 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
3398 have S_IFSOCK. This is the case under Ultrix.
3400 * posix.c (scm_status_exit_val, scm_status_exit_val,
3401 scm_status_term_sig, scm_status_stop_sig): Modified to work with
3402 Ultrix versions of WIFSTOPPED, etc., which assume that their
3403 arguments are lvalues (hmm).
3405 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
3407 * eval.c: Doc fixes.
3409 * throw.c: Doc fixes; rearranged.
3411 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
3413 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
3415 * acconfig.h: Added entry for PACKAGE.
3416 * scmconfig.h.in: Regenerated.
3418 Changes to work with automake-1.1n, which has better libtool support.
3419 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
3420 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
3422 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
3424 * Makefile.in: Rebuild.
3426 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3428 * stime.c (scm_mktime): take an optional zone argument.
3429 (scm_localtime): check putenv return value.
3430 (scm_strftime, scm_strptime): moved from posix.c. move #include
3432 stime.h, posix.h: update prototypes.
3433 (bdtime2c, setzone, restorezone): new static procedures.
3434 (scm_mktime, scm_strftime): use them.
3435 (scm_strftime): don't call mktime before strftime. Use
3436 filltime for return value.
3437 (filltime): convert NULL zname to #f.
3438 (scm_strptime): return a count of characters consumed, not
3439 the remaining string.
3441 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3443 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
3444 (scm_mktime): likewise.
3446 Uncomment localtime and mktime.
3448 * configure.in: add AC_STRUCT_TIMEZONE.
3450 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3452 * stime.c (scm_init_stime): don't define ticks/sec.
3453 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
3454 return value problem and is still portable.)
3456 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3458 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
3459 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
3460 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
3461 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
3462 cpp_err_symbols.c): Corresponding changes.
3463 * Makefile.in: Regenerated.
3465 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3467 * posix.c (scm_putenv): don't check HAVE_PUTENV.
3468 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
3469 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
3470 * putenv.c: new file, from sh-utils 1.12.
3472 * posix.c (scm_environ): use malloc in place of scm_must_malloc
3473 since allocation isn't for Scheme objects.
3474 (scm_putenv): copy strings before placing in the environment.
3476 * stime.c (scm_current_time): throw an error if time returns -1,
3477 instead of returning #f.
3478 (scm_get_internal_real_time, scm_get_internal_real_time): use
3479 scm_long2num for return value instead of SCM_MAKINUM.
3481 * stime.h: prototypes updated.
3483 * stime.c (scm_time_in_msec): apparently unused, deleted.
3485 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
3487 * configure.in: check for gettimeofday.
3489 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
3490 which may be more usefully portable than a gettimeofday interface.
3492 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
3494 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
3496 * Makefile.in: Regenerated.
3498 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3500 * stime.c (filltime): recovered static procedure.
3501 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
3504 * posix.h: add prototype for scm_close_pipe, remove prototypes for
3505 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
3507 * posix.c (scm_mknod): split the mode argument into type and perms
3508 arguments, like the extra fields returned by stat.
3510 * fports.c (scm_pipob): set the close, free and print procedures.
3511 (scm_close_pipe): new procedure.
3513 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
3514 define them in boot-9.scm
3516 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3518 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
3519 wan't defined. Don't include fd.h.
3521 * Previously fd.h was regenerated whenever configure was run,
3522 forcing a couple of files to be recompiled.
3524 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
3525 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
3526 Check for _fileno as well as _file.
3528 * ioext.c: don't fd.h.
3529 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
3532 * Change the stratigy for getting information about errno
3533 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
3534 generating lists of symbols during the build process, which will
3535 not always work, include comprehensive lists in the distribution.
3536 To help keep the lists up to date, the "check_signals" and
3537 "check_errnos" make targets can be used.
3539 * configure.in: don't check for a command to extract errno codes.
3540 * Makefile.am: update file lists, remove errnos.list and errnos.c
3541 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
3542 check_errnos targets.
3543 (CLEANFILES): remove errnos.c and errnos.list, add
3544 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
3545 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
3546 * errnos.default: deleted.

3548 * cpp_errno.c: renamed from errnos_get.c.
3549 * cpp_err_symbols, cpp_sig_symbols: new files.
3550 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
3551 * error.c (scm_init_error): #include cpp_err_symbols instead of
3553 * posix.c (scm_init_posix): don't intern signal symbols. #include
3556 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
3558 * strop.c (scm_i_index): allow the lower bound to be equal to the
3559 length of the string, so a null string doesn't always give an error.
3561 * posix.h: new prototypes.
3562 * posix.c (scm_status_exit_val, scm_status_term_sig,
3563 scm_status_stop_sig): new functions, as in scsh. They break down
3564 process status values as returned by waitpid.
3566 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
3568 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
3569 configure doesn't know about it.
3571 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3573 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
3575 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3576 which defines C variables with global linkage.
3578 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3580 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3583 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3585 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3586 has time to check why this doesn't work well with continuations.
3588 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3590 * Fix shell syntax error; some shells won't tolerate
3591 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3593 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3595 * posix.c (scm_uname): throw an error if uname fails instead
3598 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
3600 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
3603 * async.c (scm_ints_disabled): definition moved from error.c.
3605 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3607 * acconfig.h: Removed PACKAGE.
3609 * scmconfig.h.in: Regenerated.
3611 * snarf.h: g++ says it's non-portable not to specify the first
3612 argument in a varargs declaration. I introduced the first
3613 argument by using preprocessor conditionals.
3615 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3617 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3618 (scm_freopen): use RO string macros for filename and modes.
3619 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
3621 * posix.c (scm_getgrgid): simplify conversion of name to C string.
3622 (scm_mknod): use RO string macros for path.
3624 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
3625 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3627 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3628 use SCM_ROSTRINGP and SCM_ROCHARS.
3630 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3632 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3635 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
3636 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
3637 support for byte vectors.
3639 * print.c (scm_iprin1): Limit number of vector elements printed
3640 according to pstate->length.
3642 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3644 * backtrace.c (scm_display_error_message): don't segv if message
3647 * error.h: prototype for scm_error_scm.
3649 * error.c (scm_error_scm): new procedure, reimplements scm-error
3650 in C and uses scm_error.
3652 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3654 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3655 pointer to the Scheme variable read-hash-procedures and intern it
3656 in scm_init_read. Modify scm_read_hash_extend and
3657 scm_get_hash_procedure to use the pointer.
3659 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3661 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3662 (SCM_KEYWORD_STYLE): defined.
3664 * read.c (scm_read_opts): add a keywords option. This isn't a
3665 boolean option, in case someone wants to add support for DSSSL
3667 Setup scm_keyword_prefix symbol.
3668 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3670 I've left keyword support disabled by default, since it doesn't
3671 seem to break the module system and it gives R4RS standard behaviour.
3672 It can be reactivated with (read-set! keywords 'prefix).
3674 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3676 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3677 before constructing arbiter.
3679 * eval.c (scm_m_define): Bugfix: Check that the object is a
3680 closure before setting the procedure property!
3682 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3684 * ports.c: Removed `ungetc-char-ready?'.
3686 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3688 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3689 (idea from Mikael: make it a pair so scm_permanent object only
3691 (scm_read_hash_extend): don't call scm_permanent_object.
3692 (ideas from Mikael): if chr is already in the list, replace its
3693 procedure instead of appending it again. If proc is #f, remove
3695 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3697 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3699 * gdbint.c (gdb_read): update scm_lreadr usage.
3701 * load.h: update prototypes.
3703 * load.c (scm_primitive_load, scm_read_and_eval_x,
3704 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3706 * read.h: add prototype for scm_read_hash_extend. Change args for
3709 * read.c (scm_read_hash_procedures): new variable.
3710 (scm_read_hash_extend): new procedure.
3711 (scm_get_hash_procedure): new procedure.
3712 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3713 for extended # processing.
3714 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3715 scm_read_token): remove case_i, sharp arguments. Change callers.
3717 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3719 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3720 (SCM_CASE_INSENSITIVE_P): define.
3722 * read.c: add case-insensitive option to scm_read_opts.
3723 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3724 to determine whether to convert symbol case.
3725 (default_case_i): definition removed.
3726 * read.c (scm_read_token): if case_i, downcase ic before doing
3729 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3731 * configure.in: Added configuration option `guile-debug'.
3732 Configure with --enable-guile-debug if you want a bunch of extra
3733 functions used for debugging when developing Guile.
3735 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3737 * procs.c (make-cclo): New undocumented debugging procedure: Make
3738 compiled closure with internal procedure PROC and length LENGTH.
3739 Only compiled if GUILE_DEBUG is defined.
3741 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3743 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3745 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3747 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3748 with 3 or more args internally to the evaluator.
3750 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3752 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3753 with 3 or more args internally to the evaluator. This is mainly
3754 because we don't want to pass entry and exit points of the
3755 debug support twice, but it also seems to increase the speed of
3756 the evaluator for such calls (e. g. (+ 1 2 3)).
3758 * backtrace.c (scm_display_application): New procedure:
3759 display-application; Set fancy printing parameters individually
3760 for different types of display (backtrace, error, application).
3761 (These should of course be customizable!)
3763 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3764 clear the CHECK-flags.
3766 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3768 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3770 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3772 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3773 from pairs with a GLOC in the car.
3775 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3776 otherwise `symbol-hash' will behave badly.
3777 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3778 we get segmentation fault!
3780 * symbols.c: Added #include "weaks.h". New functions:
3781 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3782 moved to an extraneous library when we split libguile.)
3784 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3786 * filesys.c (scm_stat): stat now takes fport arguments too as
3787 documented in the manual.
3789 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3791 * debug.c (scm_single_step): Bugfix: Call continuation with
3792 scm_call_continuation instead of throwing to it.
3794 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3796 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3797 argument wasn't declared to be optional.
3799 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3801 * stime.c (scm_init_stime): Add feature "current-time".
3803 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3805 * throw.h: prototype for scm_exit_status.
3806 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3807 args to derive an exit status. Allows (quit) to work from a
3809 (scm_exit_status): new function.
3812 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3814 * eval.c (scm_deval): Removed some old code.
3815 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3817 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3820 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3823 * procs.c: Introduce the existent C function scm_thunk_p at the
3824 Scheme level as well.
3826 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3828 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3829 used from C to easily lookup the value of a symbol in the current
3832 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3834 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3835 scm_init_unif in this file. This will also fix a previous problem
3838 * configure.in: Added AM_MAINTAINER_MODE
3840 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3842 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3845 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3847 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3848 source files that are not always included in libguile but should
3849 have their dependencies calculated by automake. This variable is
3850 recognized by automake, no further magic is needed.
3851 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3852 to deal exclusively with *.lo files, as it seems. The *.o files
3853 are built automatically when the corresponding *.lo file gets
3856 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3858 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3861 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3863 * unif.c (scm_array_set_x): minor change to argument error checking.
3865 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3867 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3868 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3869 They should only be included in the library at configure.in's
3871 (libguile_la_LDADD): Include the appropriate .lo files here.
3872 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3873 so we know when to build them (and their .lo bretheren).
3874 * configure.in (LIBLOBJS): New substituted variable. We let
3875 configure decide which .o files to include in LIBOBJS, and then
3876 put the corresponding list of .lo files in LIBLOBJS. The latter
3877 is what we pass to libtool.
3878 * Makefile.in, configure: regenerated.
3880 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3882 * symbols.c (scm_sysintern0): New function. Contains the core of
3883 old scm_sysintern but doesn't take a second value argument.
3884 (scm_sysintern): Now uses scm_sysintern0.
3885 (scm_sysintern_no_module_lookup): Renamed to
3886 scm_sysintern0_no_module_lookup and doesn't take a second value
3887 argument any longer.
3889 * symbols.h (scm_sysintern0: Added declaration.
3891 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3892 scm_sysintern when interning option keys. Otherwise we risk
3893 destroying the values of already interned variables.
3895 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3896 scheme-level boolean (use SCM_NFALSEP).
3898 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3900 (scm_backtrace): New function. (C version of old function from
3901 boot-9.scm) Motivation: Make it possible to display backtraces
3902 without depending on boot-9.scm. (I'm uncertain if this
3903 motivation is good enough...)
3905 * root.h (scm_root_state): Add member the_last_stack_var.
3906 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3908 * root.c (mark_root): Mark scm_the_last_stack_var.
3910 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3913 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3915 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3916 1. mark_lazy_catch didn't mark the smob.
3917 2. Both functions above have standard variants:
3918 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3919 free_lazy_catch --> scm_free0.
3921 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3923 * throw.c (scm_internal_lazy_catch): New function.
3924 (scm_lazy_catch): Rewritten to use it.
3925 (scm_ithrow): Handle the new lazy catch representation.
3926 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3927 that doesn't have a jmpbuf is a lazy catch clause.
3928 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3929 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3930 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3932 (scm_init_throw): Register the new lazy-catch smob type.
3933 * throw.h (scm_internal_lazy_catch): decl for new function.
3935 * throw.c (scm_internal_catch): Doc fixes.
3937 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3938 configure.in. Including this might cause problems if applications
3939 that link against libguile include their own copies of alloca, but
3940 if they're using autoconf, they should be adding libguile to LIBS
3941 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3942 the copy in libguile, and things will be okay. (I think.)
3944 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3946 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3948 strop.h: move prototypes too.
3950 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3952 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3955 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3956 etc. I deleted them from filesys.c long ago, but didn't
3957 notice they were here too (although ineffective since
3958 sys/stat.h wasn't included).
3960 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3962 * eval.c: Don't define alloca in GCC case. gcc will automatically
3963 use __builtin_alloca if appropriate.
3965 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3967 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3968 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3969 that values of automatic variables are preserved. See comments
3970 for safe_setjmp for details.
3972 Change from Thomas Morgan:
3973 * variable.c: Include eq.h.
3974 (var_equal): New function.
3975 (variable_smob): Use var_equal as the discriminator for variables.
3977 * throw.c (s_throw): Remove extraneous declaration.
3979 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3980 * eval.c: Add necessary CPP cruft to support that.
3981 * configure, Makefile.in, scmconfig.h.in: regenerated.
3983 Change from Thomas Morgan:
3984 * procprop.c (scm_procedure_properties): Convert the Scheme
3985 boolean returned by scm_procedure_p into a C boolean before using
3986 it as a condition for SCM_ASSERT.
3987 (scm_procedure_property): Likewise.
3989 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3990 indications of Unixness.
3993 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3995 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3997 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3999 * read.c (scm_lreadr): use scm_misc_error to improve one of the
4000 "unknown # object" error messages.
4002 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
4003 (scm_i_index) and declare it static. Add a 'direction' argument
4004 to indicate what way the search should go.
4005 (scm_i_index): throw out-of-range error instead of wrong-type-arg
4007 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
4008 strop.h: remove scm_i_index, scm_i_rindex prototypes.
4010 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4012 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
4014 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
4015 to avoid clash with various scsh forks.
4017 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
4019 The following two changes (ramap.c, throw.c) are motivated by the
4020 apparent unportability of forward declarations of static arrays of
4021 the form `static foo bar[];'.
4023 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
4024 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
4026 * throw.c (scm_throw): Moved above scm_ithrow.
4028 * options.h: Removed the extern declarations of scm_yes_sym and
4029 scm_no_sym since these are static.
4031 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4033 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
4035 * Makefile.am: remove AWK=@AWK@.
4036 Add a rule for generating errnos.list.
4037 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
4039 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
4040 don't extract errnos, just set a variable (avoids the
4041 need to recompile error.c just because configure is run.)
4043 * unif.h: update prototypes.
4044 * unif.c (scm_uniform_array_read,write): change the offset and
4045 length arguments to start and end, for consistency.
4047 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
4049 * ioext.h: update prototypes.
4050 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
4051 scm_read_line_x, it's a more general procedure using an
4052 interface from scsh. read-line and read-line! are now defined
4054 Note that the new read-line trims the terminator
4055 by default, previously it was appended to the returned string. An
4056 optional argument specifies how to process the terminator (scsh
4057 compatible). For the old behaviour: (read-line port 'concat).
4058 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
4059 returns a pair, but is converted to multiple values if the scsh
4062 socket.h: update prototypes.
4063 * socket.c (scm_recvfrom): for consistency with other procedures,
4064 take start and end as separate optional arguments.
4065 (scm_recv, scm_recvfrom): don't allow the second argument
4066 to be a size, only a buffer. Change the scheme names to
4067 recv! and recvfrom!. Don't return the buffer.
4069 * ioext.h, posix.h: move prototypes too.
4070 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
4071 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
4072 "read.h" and "unif.h".
4073 * ioext.c: include "chars.h"
4075 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
4077 * dynl.c: The dynamic linking and module registration functions
4078 are now defined even when dynamic linking is not available for the
4079 host system. Some of their functionality can be done without
4080 dynamic linking; when it's really needed, they throw errors.
4082 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
4084 * configure.in: Only define DYNAMIC_LINKING when one of the system
4085 dependent functions is detected.
4086 * dynl.c (scm_dynamic_func): New function to get the address of a
4087 function in a dynamic object.
4088 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
4089 produced by scm_dynamic_func as the thing to call.
4091 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
4093 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
4094 (scm_register_module_xxx, scm_registered_modules,
4095 scm_clear_registered_modules): New functions.
4097 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
4099 * symbols.c (scm_sysintern): Renamed to
4100 scm_sysintern_no_module_lookup.
4101 (scm_sysintern): New function to take the place of the old
4102 scm_sysintern. It uses the current toplevel lookup closure to give
4103 the symbol its value. This is a temporary hack to put packages
4104 like gtcltk into their own module.
4105 (scm_can_use_top_level_lookup_closure_var): New variable to tell
4106 us whether `scm_top_level_lookup_closure_var' has been initialized
4108 * eval.c (scm_init_eval): Set it.
4110 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
4112 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
4113 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
4115 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
4117 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
4118 scm_sys_dup): deleted: FD capability will be added to other
4120 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
4121 scm_fd_free, fd_smob, scm_intern_fd.
4122 (scm_open): renamed from scm_sys_open. Return a port instead of
4123 an FD object. Make the mode argument optional.
4124 (scm_sys_create): deleted, it's just a special case of open.
4125 (scm_init_filesys): move interning of constants O_CREAT etc.,
4126 here (were previously using SCM_CONST_LONG macro).
4127 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
4129 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
4130 include "fports.h" and <stdio.h>
4131 (scm_stat, scm_select): don't support FD objects.
4133 * error.h: adjust scm_syserror_msg prototype.
4134 * error.c (scm_syserror_msg): take an extra argument for errno.
4135 Using the global value didn't always work, since it could be
4136 reset by procedure calls in the message or args arguments.
4138 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
4139 I don't understand why the check was there (and what about the
4142 * strop.c (scm_string_copy): allow shared substrings to be copied.
4144 * unif.h: corresponding change to prototypes.
4145 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
4146 recognize two new optional arguments: offset and length. Allow
4147 the port argument to be an integer (file descriptor, for scsh).
4148 Include <unistd.h> for "read" prototype.
4150 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
4152 * socket.c: don't include filesys.h.
4154 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
4156 * Makefile.am: add AWK=@AWK@ (?)
4158 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
4160 Add a rule to generate errnos.c from errnos.
4161 * error.c (scm_init_error): include errnos.c.
4162 * errnos_cnvt.awk: new file, converts the list of errno codes to
4164 * errnos_get.c: new file.
4165 * errnos.default: new file, contains errnos to try if they can't
4166 be extracted from errno.h.
4167 * configure.in: if using GCC, try and extract errno codes from
4171 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
4173 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
4174 * Makefile.am: Made libguile into a libtool library.
4175 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
4176 Set libtool_libs to indicate that libguile is a libtool library.
4177 See guile/ChangeLog for details.
4178 * .cvsignore: ignore "*.lo", the libtool library objects.
4180 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
4182 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
4183 use htons in getservbyport argument.
4185 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
4187 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
4188 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
4191 * objprop.c (scm_object_property): No need to take the CDR of the
4192 value returned by scm_object_properties, since Aug 20 change.
4194 * configure.in: When checking for struct linger, #include
4195 <sys/types.h> as well as <sys/socket.h>. I've never known
4196 <sys/types.h> to cause any portability problems, and Solaris's
4197 <sys/socket.h> needs it.
4198 * configure: Rebuilt.
4200 I think the Sun compiler has chosen a perverse way to interpret
4201 ANSI declarations combined with K&R definitions. We'll
4202 appease it a little bit. But when it invades France, we fight.
4203 * print.c (scm_iprlist): Change 'tlr' argument to an int.
4204 * print.h (scm_iprlist): Here too.
4205 * numbers.c (scm_divbigdig): Change definition to match
4206 declaration in numbers.h.
4207 * unif.c (scm_makflo): Change definition to match declaration in
4210 * init.c (scm_boot_guile): Don't return the value of
4211 scm_boot_guile_1. This function doesn't return a value;
4212 scm_boot_guile_1 doesn't return a value (or return at all).
4214 * eval.c (unmemocopy): Add a semicolon to appease the Sun
4217 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
4218 compile. I have a feeling this function is a bad idea anyway ---
4219 one should always test for features, not systems.
4221 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
4222 semicolons. Only pure luck kept this from being noticed earlier.
4224 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
4226 * socket.c (scm_recvfrom): Added missing semicolon.
4228 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4230 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
4231 the buffer and start and end positions for scsh networking
4234 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
4236 * configure.in: Revert previous change to this file; the problem
4237 is due to transient automake weirdness.
4238 * configure: Rebuilt.
4240 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
4241 PLUGIN/guile.libs. configure generates the latter from the former.
4242 * Makefile.in: Rebuilt.
4244 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
4245 need this if we install scripts, like guile-snarf.
4246 * configure: Rebuilt.
4248 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
4250 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
4252 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
4254 * socket.c (scm_addr_vector): fix faulty scm_listify.
4256 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
4258 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
4259 style block comment is no longer considered an error.
4261 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
4263 * PLUGIN/guile.libs.in: New file.
4264 * PLUGIN/guile.libs: Removed from repository.
4265 * configure.in: Create PLUGIN/guile.libs from
4266 PLUGIN/guile.libs.in. This is for including additonal libraries
4267 needed for dynamic linking.
4268 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
4269 instead of PLUGIN/guile.libs.
4271 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
4273 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
4275 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
4276 occurrences of the given element from the list, not just the
4277 first. This is how the Emacs Lisp functions behave, how the
4278 analogous Common Lisp functions behave, and (I believe) how the
4279 older Maclisp functions worked. I realize that this change may
4280 break code, but it seemed better to break it before the Guile
4283 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
4284 Their prototypes were already present in gc.h, but they weren't
4286 (scm_init_storage): Initialize scm_protects.
4287 * root.c (scm_protects): New element of scm_sys_protects.
4289 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
4291 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4293 * libguile.h: Added #include "libguile/net_db.h".
4295 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
4296 30 change. That file is only meant for communication between the
4297 configuration process and load.c. If code linked against libguile
4298 wants to get at the paths mentioned in libpath.h, it can call
4299 functions declared in load.h.
4301 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4303 * libguile.h: Removed #include "libguile/fdsocket.h"
4305 * net_db.c: Added #include <sys/socket.h>.
4307 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
4309 * filesys.c (scm_input_waiting_p): use select in preference to
4310 FIONREAD, since the latter doesn't detect EOF.
4311 Throw error if neither select nor FIONREAD available.
4313 * socket.c (scm_connect): take a port, not a fd object.
4314 (scm_fill_sockaddr): throw an error if fam is not recognised.
4315 (scm_bind): use scm_fill_sockaddr.
4316 (scm_listen): take a port, not a fd object.
4317 (scm_accept): take and return a port. return #f in the car if
4318 address can't be got
4319 (scm_sock_fd_to_port): new procedure.
4320 (scm_socket): use scm_sock_fd_to_port.
4321 (scm_addr_vector): throw error if unrecognised address type.
4322 take an extra argument with the calling procedure name.
4323 (scm_getsockname): take a port. return #f if address can't be got.
4324 (scm_getpeername): take a port. return #f if address can't be got.
4325 (scm_recvfrom): take a port. return #f for address component if can't
4327 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
4328 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
4330 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
4332 * throw.c (scm_internal_catch): Make body funcs and handler funcs
4333 use separate data pointers, to allow them to be designed
4334 independently and reused.
4335 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
4336 Renamed from catch_body, catch_handler, and uncaught_throw; made
4338 (struct scm_catch_body_data): Renamed from catch_body_data; moved
4340 (scm_catch): Use the above.
4341 (scm_throw): Don't bother printing a message for an uncaught
4342 throw; we establish a default handler in init.
4343 * throw.h (scm_internal_catch): Prototype updated.
4344 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
4346 (struct scm_body_thunk_data): New structure, used as data
4347 argument to scm_body_thunk.
4348 * init.c (struct main_func_closure): New structure, packaging up
4349 the data to pass to the user's main function.
4350 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
4351 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
4352 scm_internal_catch to establish a catch-all handler, using
4353 scm_handle_by_message. This replaces the special-case code in
4355 (invoke_main_func): Body function for scm_internal_catch; invoke
4356 the user's main function, using the main_func_closure pointer to
4357 decide what to pass it.
4358 * root.c (struct cwdr_body_data): Remove handler_proc member.
4359 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
4360 (cwdr_handler): Removed.
4362 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4364 * socket.h (SCM_P): update bind prototype.
4365 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
4366 include "feature.h".
4367 (scm_socket): return a port, not a file descriptor object.
4368 include "fports.h" and <unistd.h>
4369 (scm_bind): take a port, not a file descriptor object.
4370 take an extra argument for address args.
4372 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
4373 INADDR_NONE, INADDR_LOOPBACK.
4375 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4377 * init.c: include net_db.h and not fdsocket.h.
4378 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
4380 * Makefile.am: corresponding changes.
4381 * socket.h: renamed from fdsocket.h, fix names.
4382 * net_db.h: renamed from socket.h, fix names.
4383 * socket.c: renamed from fdsocket.c.
4384 remove _sys from procedure names.
4385 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
4386 add "socket" to features list.
4387 * net_db.c: renamed from socket.c.
4388 remove _sys from procedure names.
4389 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
4390 add "net-db" to features list.
4391 include "net_db.h". don't include <sys/socket.h> or
4394 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4396 * tags.h (scm_tags): Removed comma at end of last enumerator.
4398 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
4400 Don't use GCC extensions to allocate space for debugging frames.
4401 (Here he goes again! Why do we put up with this?!)
4402 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
4403 an scm_debug_info structure, not an in-line array of them. Add
4404 'info' member, to say how many vect elements we've used, for eval
4406 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
4407 a new variable debug_info_end to mark the end of vect, instead of
4408 the address of the 'info' pointer itself.
4409 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
4410 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
4411 (SCM_APPLY): Explicitly allocate space for debug.vect.
4412 * debug.c (scm_m_start_stack): Same, for vframe.vect.
4413 * stacks.c: Adjusted for new debug frame structure.
4414 (RELOC_INFO, RELOC_FRAME): New macros.
4415 (stack_depth, read_frames): Use them, and new scm_debug_frame
4416 element 'info', instead of magically knowing that eval frames have
4417 an info pointer sitting after vect.
4418 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
4420 (scm_init_stacks): Formatting tweaks.
4422 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
4424 Give GCC more control flow information, so it can be sure that
4425 variables aren't used uninitialized.
4426 * error.h (scm_error, scm_syserror, scm_syserror_msg,
4427 scm_sysmissing, scm_num_overflow, scm_out_of_range,
4428 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
4429 scm_misc_error): Tell GCC that these functions never return.
4430 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
4431 out the field type, call abort if SCM_ASSERT returns, to placate
4433 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
4434 scm_wta ever returns. We can't handle this case anyway, and this
4435 gives the optimizer more information.
4436 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
4437 scm_wta ever returns.
4439 In some cases, the code is fine, but GCC isn't smart enough to
4440 figure that out; this usually happens when one variable is only
4441 initialized and used when a particular condition holds true, and
4442 we know that condition will never change within a given invocation
4443 of the function. In this case, we simply initialize the variables
4444 to placate the compiler, hopefully to a value which will cause a
4445 crash if it is ever actually used.
4446 * print.c (scm_iprin1): Initialize mw_pos.
4447 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
4448 * throw.c (scm_ithrow): Initialize dynpair.
4449 * unif.c (scm_uniform_vector_ref): Initialize cra.
4450 * struct.c (init_struct): Initialize prot.
4451 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
4453 * strports.c (scm_eval_0str): Don't return uninitialized garbage
4454 if EXPR contains no expressions.
4456 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4458 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
4459 cause an infinite loop (???). So much for the algebraic
4460 equivalency of variable-sized arrays and alloca...
4462 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
4464 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
4465 a SCM boolean, not a C boolean.
4467 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
4469 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
4470 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
4471 rules for raising scm_mtrigger. Previously, unfortunate but not
4472 unlikely circumstances could result in almost constant invokation
4473 of the gc. Now, this situations should be less likely, but they
4474 are not prevented completely.
4476 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
4478 * numbers.c (scm_fuck): Procedure removed; looks like old test
4480 * numbers.h: Prototype removed.
4482 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
4484 * debug.h (scm_debug_frame): Change `vect' member from an in-line
4485 array to a pointer, to match my Nov 21 change in eval.c.
4487 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4489 * libguile.h: Added #include "libguile/backtrace.h", #include
4490 "libguile/stacks.h".
4492 * strings.c (scm_string scm_make_string scm_string_ref
4493 scm_string_set_x scm_string_equal_p scm_string_append):
4494 Bugfix according to scm patch from Aubrey Jaffer:
4495 Corrected long-standing
4496 (not (eqv? (integer->char 128)
4497 (string-ref (make-string 1 (integer->char 128)) 0)))
4498 bug found by John Kozak <jk@noontide.demon.co.uk>.
4500 * strports.c, strports.h: Make scm_eval_0str return the value of
4501 the last expression evaluated (previously, it returned void).
4503 * strports.c, strports.h: New function: scm_read_0str. Does what
4506 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4508 * simpos.c (scm_getenv): return #f if string can't be found in the
4509 environment instead of throwing an exception, for compatibility
4510 with numerous other systems.
4512 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
4514 * Makefile.am (.c.x): Use guile-snarf.
4515 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
4517 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
4519 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4521 * backtrace.c (scm_display_error_message): Made non-static, and
4522 renamed from display_error_message.
4523 * backtrace.h (scm_display_error_message): Added extern decl.
4524 * throw.c (uncaught_throw): Use it to display the error message.
4526 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
4528 * inet_aton.c: Use #if 0, not #ifdef 0.
4530 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
4532 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
4533 to convert the returned value.
4534 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
4535 the offset argument.
4537 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4539 Add new interface to catch/throw, usable from C as well as
4541 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
4542 (scm_internal_catch): New function, replaces...
4543 (scm_catch_apply): Deleted.
4544 * throw.c (scm_catch_apply): Deleted; replaced with a more general
4545 mechanism which is a bit more code, but can be used nicely from C
4546 and implement the Scheme semantics as well.
4547 (scm_internal_catch): This is the replacement; it's named after
4548 the analogous function in Emacs.
4549 (scm_catch): Reimplemented in terms of the above.
4550 (struct catch_body_data, catch_body, catch_handler): New
4551 functions, used by scm_catch.
4552 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
4553 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
4554 support for new cwdr.
4556 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
4559 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
4561 * acconfig.h: Added DYNAMIC_LINKING symbol.
4562 * configure.in: Add option and checks for dynamic linking.
4563 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
4564 dynl.h: New files for dynamic linking support.
4565 * Makefile.am (libguile_a_SOURCES):
4567 (modinclude_HEADERS): Added "dynl.h".
4568 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
4570 * init.c (scm_boot_guile_1): Call
4571 scm_init_dynamic_linking to initialize dynamic linking support.
4573 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
4575 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4576 (as we Schemers say). It needs to be global, so that I can tweak
4577 it for the proper operation of unexec.
4578 (scm_boot_guile_1_live): New variable, see above.
4580 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4582 * guile-snarf.sh: Removed.
4583 * PLUGIN/guile.libs: Added dependency for -lm.
4584 * acinclude.m4: Renamed from aclocal.m4.
4585 * PLUGIN/greet: Removed.
4586 * Makefile.am, aclocal.m4: New files.
4587 * configure.in: Updated for Automake.
4589 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4591 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4592 and not top_level_lookup_thunk_var.
4594 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4596 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4598 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4600 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4601 Scheme function, instead of syntax. Single argument is now a
4604 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4606 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4607 scm_ra_divide): Properly terminate statements passed as arguments
4608 to IVDEP macros. (Thanks to Bernard Urban.)
4610 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4611 with non-constant sizes. (Thanks to Bernard Urban.)
4613 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4615 It's an "eval closure", not an "eval thunk." A thunk is a
4616 function of no arguments.
4617 * root.h (struct scm_root_state): Renamed
4618 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4619 (scm_top_level_lookup_closure_var): Renamed from
4620 scm_top_level_lookup_thunk_var.
4621 * root.c (mark_root): Uses changed.
4622 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4623 * init.c (scm_start_stack): Uses changed.
4624 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4625 Change scheme-visible name to *top-level-lookup-closure* from
4626 *top-level-lookup-thunk*.
4628 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4630 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4631 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4633 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4635 * gc.c (struct scm_heap_seg_data): Doc fixes.
4637 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4638 sweeping. Then, prepend each segment's free cells to its
4639 freelist, rather than wiping out the old value. (Thanks to Marius
4642 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4643 scm_check_freelist, scm_debug_newcell): New functions and
4644 variables, for debugging freelist problems.
4645 * pairs.h (SCM_NEWCELL): New debugging version added.
4646 * gc.h (scm_debug_newcell): Added extern declaration, used by
4647 debugging version of SCM_NEWCELL.
4649 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4651 On some systems <libc.h> conflicts with <unistd.h>, and should not
4652 be #included at all.
4653 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4654 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4655 * configure.in: Call it.
4656 * posix.c, filesys.c: Use its results to decide whether or not to
4658 * configure, scmconfig.h.in: Rebuilt with autoconf and
4661 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4663 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4664 pointer to the stdio stream before calling scm_setbuf0, so the
4665 latter will be able to retrieve it. I'm surprised this didn't
4666 segfault earlier. (Thanks to Christopher Lee.)
4668 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4670 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4673 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4675 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4676 number of stack narrowing specifier pairs. The first specifier in
4677 a pair controls inner border, the second the outer border. A
4678 number means cut that number of frames, a procedure object means
4679 cut until that object is found in operator position in a frame.
4681 * root.c (cwdr): Bugfix.
4683 * read.c: Recording of positions disabled by default.
4685 * procs.c (scm_closure_p): New function.
4687 * posix.c (scm_tmpnam): New function.
4689 * load.c: Added #include "throw.h".
4690 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4693 * load.c, load.h (scm_read_and_eval_x): New function.
4695 * eval.c: Renamed debug option "deval" to "debug".
4697 (scm_eval_x): `eval!' is no longer accessible from the scheme
4698 level. Motivation: We can't allow operations which introduce
4699 glocs into the scheme level. Guile's type system can't handle
4700 these as data. Use `eval' or `read-and-eval!' as replacement.
4702 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4703 SCM_CONSP since this is a macro!; Set vframe.prev to
4704 scm_last_debug_frame instead of 0. In this way we can look
4705 "above" the virtual start stack frame if we wish.
4706 (scm_debug_hang): New function: Useful for debugging Guile in
4707 certain tricky situations. Will probably be removed later...
4709 * debug.h: Changed semantics of debug option "backtrace". This
4710 option now only indicates whether we want automatic backtrace at
4713 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4715 * ports.c: #include "filesys.h"
4716 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4718 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4719 Motivation: This is system specific code which is related to file
4720 I/O. It also may use select. Added code by Gary Houston to
4721 detect presence of character in stdio buffers.
4723 * libguile.h: #include "libguile/libpath.h"
4725 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4726 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4727 SCM_SITE_DIR; Install libpath.h among the other include files.
4729 * load.c, load.h (scm_sys_package_data_dir): New function.
4731 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4733 * stacks.h: Bugfix: Don't use tail-array length field as stack
4734 length field! This screwed GC.
4736 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4738 * _scm.h: Added #ifndef around definition of macros min and max.
4740 * __scm.h: Added hooks for threads to plugin to in ints protection
4741 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4742 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4743 the main code in these macros duplicated and spread over multiple
4744 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4745 SCM_THREAD_SWITCHING_CODE.
4747 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4749 * snarf.h: New file.
4750 * guile-snarf.sh: New file.
4751 * Makefile.in (inner_h_files): Added snarf.h
4752 (ancillary, install, uninstall, distclean): Added actions for
4754 (.c.x): Use guile-snarf.
4755 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4756 (gen_c_files): Note that these depend on guile-snarf.
4757 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4758 now in "snarf.h". Added #include "snarf.h" to get them.
4759 * libguile.h: Added #include "snarf.h".
4760 (Patches applied and tweaked by Jim Blandy.)
4762 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4764 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4765 standards suggest against providing prototypes for system
4766 functions. Thanks to Greg Troxel.
4768 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4770 * strports.c (scm_eval_0str): New function.
4771 #include "read.h", to get prototype for scm_read.
4772 * Makefile.in (strports.o): Update dependencies.
4773 * strports.h: New prototype.
4775 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4776 scheme name from "int?" to "integer?". It seems to do the job.
4777 * numbers.h: Rename prototype too.
4778 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4781 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4782 scm_num_eq_p): Rename these according to R4RS conventions: call
4783 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4784 to making libguile R4RS compliant without ice-9...
4786 * load.c (scm_sys_search_load_path): Search for files under all
4787 extensions listed in the %load-extensions variable. If FILENAME
4788 is absolute, return it unchanged, without searching the load path.
4789 (scm_loc_load_extensions): New variable, pointing to
4790 %load-extensions' value cell.
4791 (scm_init_load): Initialize it, and the value it points to.
4792 (scm_primitive_load_path): Improve error reporting.
4794 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4795 of new Scheme variable %load-hook.
4796 (scm_primitive_load): Apply %load-hook to filename.
4798 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4800 * configure.in: add tests for figuring out whether buffered data
4801 is available in a FILE structure, which is needed by char-ready.
4803 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4806 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4807 exceptions using misc_error instead of syserror. It seems a bit
4808 odd to throw an exception if a string can't be found in the
4809 environment, but it's consistent with open-file, stat etc.
4810 (simpos.h): remove sys_ from getenv.
4812 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4813 occurs, throw an error instead of returning errno. Return value
4815 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4817 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4819 * filesys.c (scm_stat2scm): derive file type and permissions from
4820 the stat mode and append them to the returned vector.
4821 There isn't much overhead in doing this and it avoids the need to
4822 work with S_IRUSR et al. in Scheme.
4823 Define symbols scm_sym_regular etc.
4824 (scm_init_filesys): don't intern S_IRUSR etc.
4826 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4827 and s_primitive_load_path.
4829 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4831 * error.h: don't declare error symbols. prototype for scm_misc_error.
4833 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4836 * error.c: use SCM_SYMBOL to set up error keys.
4837 scm_misc_error: new procedure.
4839 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4841 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4842 between `#!' and `!#' is ignored.
4843 (skip_scsh_block_comment): New function.
4845 * feature.c (scm_set_program_arguments): New argument, FIRST.
4846 * feature.h: Update prototype.
4847 * init.c (scm_boot_guile_1): Pass new argument to
4848 scm_set_program_arguments.
4850 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4852 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4853 (scm_boot_guile): Call scm_set_program_arguments here, later than
4854 the old initialization.
4856 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4857 initialization procedure.
4858 - Delete in, out, err arguments; there are other perfectly good
4859 ways to override these when desired.
4860 - Delete result argument; this function shouldn't ever return.
4861 - Rename init_func argument to main_func, for less confusion.
4862 - Delete boot_cmd argument; main_func is more general.
4863 -Add 'closure' argument, to help people pass data to main_func
4864 without resorting to global variables.
4865 - Abort if reentered; don't bother returning an error code.
4866 - Call scm_init_standard_ports to set up the default/current
4867 standard ports; no need to pass them to scm_start_stack.
4868 - Remove code to evaluate the boot_cmd, and start the repl; let
4869 the user do something like that in main_func if they want.
4870 - Remove code to package up a return value; main_func can do any
4872 - Call exit (0), instead of returning.
4873 (scm_start_stack): Don't initialize the I/O ports here; that's
4874 weird. Delete in, out, err arguments. Move guts to
4875 scm_init_standard_ports, scm_stdio_to_port.
4876 (scm_init_standard_ports): New function, to set up current and
4877 default standard ports.
4878 (scm_start_stack, scm_restart_stack): Make these static.
4879 * init.h (scm_boot_guile): Adjust declaration.
4880 (scm_start_stack, scm_restart_stack): Remove externally
4881 visible declarations for these.
4882 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4884 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4885 written out several times in scm_start_stack.
4886 * fports.h: New declaration for the above.
4888 * feature.c (scm_set_program_arguments): New function.
4889 * feature.h: New declaration for the above.
4891 * ports.c: Formatting tweak.
4893 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4895 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4896 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4897 for obtaining the address of a car or cdr field. Motivation:
4898 &SCM_CXR make assumptions about the internal structure of the
4901 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4902 Motivation: see SCM_CXRLOC.
4904 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4905 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4906 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4907 Motivation: Safer use. Some other macros are defined in terms of
4908 these operations. If these are defined using the SCM_SETCXR
4909 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4910 to inefficiency and an <e1> with side-effects could potentially
4911 break. Also, these particular operations are heavily utilized in
4912 the garbage collector. In unoptimized code there will be a
4915 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4916 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4917 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4918 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4919 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4920 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4921 vports.c: Cleaned up use of pairs: Don't make any special
4922 assumptions about the internal structure of selectors and
4923 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4924 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4925 (Among other things, this change makes it easier to build Guile
4926 with certain compilers which have problems with casted lvalues.)
4928 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4930 * stacks.c: Improve selection of relevant stack frames when making
4931 a stack object. Introduce one level of indirection in the stack
4932 object to make it possible to "narrow" to a certain region of the
4933 stack. This facilitates making use of more clever algorithms (not
4934 implemented) for selecting relevant frames and gives a cleaner
4935 design since selection of frames can be done independently of
4936 extraction of frames from the real stack.
4937 (scm_stack_id): Also take #t as argument which means look at
4940 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4941 Turn n_tail into an integer directly representing current number
4942 of frames in stack. Add field tail.
4944 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4946 * debug.c (scm_make_memoized): Made it available at scheme level.
4947 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4948 SCM_NIMP before applying heavier predicates in argument checking.
4949 (scm_local_eval): Also take memoized object as argument.
4951 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4952 aren't created with zero length, but should such a strange
4953 creature suddenly turn up...
4955 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4957 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4958 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4960 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4962 * variable.c (scm_make_variable): Make the name hint optional, as
4964 (anonymous_variable_sym): Renamed from variable_sym. All uses
4967 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4968 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4969 of scm_primitive_load_path was also changed to
4970 "primitive-load-path", from "%try-load-path". Callers changed.
4971 We'd like to respect the convention that a function named
4972 "try-mumble" should behave just like the function called "mumble",
4973 but return #f instead of signalling some error.
4974 * load.h: Rename prototypes.
4976 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4978 * print.c (make_print_state, grow_print_state), print.h: Modified
4979 the print state representation: Don't use a tail array for
4980 recording of circular references. Resizing of the print state
4981 structure invalidates the print state pointer. To avoid passing
4982 around an indirect print state reference to all printing
4983 functions, we instead let the print state reference a resizable
4986 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4988 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4989 Don't crash when passed an improper list terminated by a
4990 non-immediate value.
4992 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4994 Allocate data for structures on an eight-byte boundary, as
4995 required by the tagging system.
4996 * struct.c (alloc_struct): New function.
4997 (scm_make_struct, scm_make_vtable_vtable): Call it.
4998 * struct.h (scm_struct_n_extra_words): Bump to 3.
4999 (scm_struct_i_ptr): New "field".
5000 * gc.c (scm_gc_sweep): When we need to free the data, use the
5001 information stored by alloc_struct to find the beginning of the
5002 block allocated to the structure, so we can free it.
5004 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5006 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
5009 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
5010 (scm_debug_info): New member: id.
5012 * stacks.c: Stacks are now represented as structs; Stacks have an
5013 id given to them by `start-stack'.
5014 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
5016 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
5017 Changed stack representation.
5019 * debug.c (scm_procedure_name): Try procedure property `name' for
5020 compiled closures aswell.
5022 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
5024 * eval.c: scm_i_name moved to gsubr.c
5025 (scm_m_define): Record names of all kinds of procedure
5026 objects. (Earlier, only closures were recorded.)
5028 * procprop.h: Added declaration of scm_i_name.
5030 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
5031 (scm_make_gsubr): Record names of compiled closures.
5033 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5035 * debug.c, debug.h: Removed obsolete code.
5037 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
5038 stacks.c: Renamed regs --> scm_contregs.
5040 * print.c (scm_free_print_state): Cleanup print state before
5041 returning it to pool. It is better to do it here than in
5042 scm_prin1 since scm_prin1 is called often.
5044 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
5045 s_set_source_property_x): Check that first argument is a pair or a
5048 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
5049 scm_i_line, scm_i_column and scm_i_breakpoint global.
5051 * init.c: Added #include "backtrace.h" and #include "stacks.h".
5052 (scm_boot_guile_1): Added calls to scm_init_backtrace and
5055 * debug.h: Added debug object smob declaration and macro
5058 * configure.in: Build with backtrace.o and stacks.o if debug
5061 * Makefile.in: Added entries for new files: backtrace.c,
5062 backtrace.h, stacks.c and stacks.h.
5064 * symbols.c (scm_sym2ovcell): Fixed documentation.
5066 * _scm.h (min, max): Added.
5068 * async.c: Moved `min' macro to _scm.h.
5070 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
5071 SCM_BACKTRACE_INDENT.
5073 * eval.c: Added new debug options `maxdepth' and `indent'.
5075 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
5077 * print.h: Added selector SCM_PRINT_STATE.
5079 * print.c: New functions: scm_make_print_state,
5080 scm_free_print_state.
5082 * print.h: Added declarations for scm_make_print_state,
5083 scm_free_print_state.
5085 * debug.c (scm_m_start_stack): New acro.
5087 * debug.h: Small cleanup.
5089 * init.c (scm_boot_guile_1): Moved scm_init_debug below
5092 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

5114 declare functions with prototypes. (Patch thanks to Marius
5117 More prototype-related changes from Marius Vollmer:
5118 * gdb_interface.h: Wrapped header file in #ifdef/#endif
5119 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
5120 * ports.h (ptobfuns): Added prototypes. This means some casting in
5122 * fports.c: Added casts for initializations, since the functions
5123 are defined to take FILE * as their stream argument, not SCM.
5124 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
5125 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
5126 to `char *str_data' to conform to prototype.
5128 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5130 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
5132 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
5134 * stime.c, stime.h: use SCM_P method.
5136 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
5138 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
5139 be given at least two arguments. Insist that lst's last element
5140 be a list, but don't make any requirements of its predecessors.
5142 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
5144 * eval.c (scm_nconc2last): Revert last change; there seems to be
5145 other stuff going on here.
5147 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5149 * eval.c (scm_nconc2last): Make sure that each element of lst
5150 (which is a list of argument lists, except for the tail) is a
5151 proper list, i.e., finite and terminated by '().
5153 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
5155 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
5158 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
5159 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
5162 * vectors.c (scm_make_vector): Fill vectors with the undefined
5163 value, to help make Guile Scheme code more portable to other
5166 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
5167 * symbols.h, tags.h: Doc fixes.
5169 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
5171 * async.c (scm_take_signal): Doc fixes.
5173 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
5175 * numbers.c (scm_divbigint): When the remainder is zero, we don't
5176 want to subtract it from the modulus; we just want to leave it
5179 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
5181 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
5184 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
5186 * throw.c (scm_catch_apply): Finished implementation of
5189 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
5191 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
5193 (scm_init_filesys): set "i/o-extensions" feature.
5196 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
5198 * Makefile.in (root.o): Correct dependencies.
5200 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
5202 * Makefile.in: Added dependency entry for root.o.
5204 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
5205 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
5207 * init.c (scm_start_stack): Set initial root continuation number
5210 * procs.c: New function: scm_thunk_p.
5212 * procs.h: Added declarations of scm_thunk_p.
5214 * root.c: Renamed `call-with-new-root' -->
5215 `call-with-dynamic-root'.
5216 (cwdr): Removed allocation of new root state. This should be done
5217 separately by use of scm_make_root.
5218 (scm_apply_with_dynamic_root): New function: Does what it
5219 sounds like. Needed when spawning threads.
5221 * root.h: Added member last_debug_frame to root state.
5222 Added #include "libguile/debug.h"
5224 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
5225 arguments. The motivation is that code in root.c needs catch
5226 functionality, and we want to avoid code duplication.
5227 New functions: scm_catch, scm_lazy_catch. These are wrappers for
5228 scm_catch_apply. scm_lazy_catch is intended to introduce catch
5229 handlers that run without popping the stack into the dynwind
5232 * throw.h: Added prototypes for scm_catch_apply and
5235 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5237 * root.h (scm_root, scm_set_root): Decouple thread support details
5238 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
5239 SCM_SET_THREAD_LOCAL_DATA.
5241 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
5242 and tortoise scanning loop.
5244 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
5246 * Makefile.in: Rebuild dependencies.
5248 * libguile.h: #include "libguile/print.h" before "smob.h", since
5249 the latter uses the print_state structure.
5251 * throw.c (scm_ithrow): Use the correct variable when checking to
5252 see if a given element of scm_dynwinds is a valid catch.
5254 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
5255 structure, abort; don't just silently ignore the garbage.
5257 * _scm.h: #include "print.h" here, since it seems to be used just
5259 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
5260 strports.c, unif.h: Don't #include "print.h".
5262 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5264 * feature.h (scm_loc_features): Removed external declaration.
5265 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
5267 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5269 * feature.c (scm_init_feature): Added threads feature (needs to be
5270 initialized here, since features doesn't exist when
5271 scm_init_threads is called).
5273 * libguile.h: Added #include "libguile/../threads/threads.h".
5274 (This is a kludge to get thread support working. This should be
5277 * configure.in, acconfig.h: Added flags for thread support.
5279 * scmsigs.c: Define `signal' to be `pthread_signal' if using
5282 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
5283 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
5286 * _scm.h: Added conditional #include "threads.h"
5288 * __scm.h (SCM_ASYNC_TICK): Added call to macro
5289 SCM_THREADS_SWITCHING_CODE.
5291 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
5292 allocate the basic dynamic root object.
5293 (scm_boot_guile): Added call to scm_init_root.
5295 * root.c, root.h: Added root smob.
5296 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
5297 functions: Implements dynamic roots mostly according to spec in
5298 SCM manual. Main difference is that the second argument is a
5299 throw handler rather than an error "thunk".
5301 * root.h: Added declaration of scm_init_root.
5303 * root.c: Added #include "genio.h", #include "smob.h", #include
5304 "pairs.h", #include "throw.h", #include "dynwind.h", #include
5306 (scm_init_root): Added #include "root.x".
5308 * throw.c: Added #include "stackchk.h"
5309 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
5310 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
5311 can be used in scm_call_with_new_root; Added reenabling of stack
5312 checking when catching a throw.
5314 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
5316 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
5318 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
5319 element is not found, as per R4RS.
5321 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5323 * list.c: Doc fixes throughout.
5325 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
5327 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
5328 declare the char * to be const. Avoids a warning in rgx.c.
5330 * ports.h: spelling fix.
5332 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
5335 * load.c (scm_sys_try_load_path): throw an error if file not found
5336 (like it says it in NEWS).
5338 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5340 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
5341 PROPS slot to '(), not #f; it's an empty alist.
5343 * throw.h, throw.c: Use SCM_P instead of #if hair.
5345 Remove special support for uncaught throws; see throw.c for
5347 * throw.c (uncaught_throw): New function.
5348 (scm_ithrow): Call uncaught_throw if we don't find a throw
5349 target; don't mess with scm_bad_throw_vcell.
5350 (scm_bad_throw_vcell): Variable deleted.
5351 (scm_init_throw): Don't initialize it.
5353 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
5356 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
5358 * numbers.c (scm_istr2int): If the number is short (as most
5359 numbers are), just call scm_small_istr2int to deal with it.
5360 (scm_small_istr2int): New function, created by un-#ifdefing the
5361 non-bignum version of scm_istr2int and renaming it.
5363 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
5365 * load.c (scm_sys_try_load): don't check whether value returned
5366 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
5367 Change the Scheme name from %try-load to primitive-load.
5369 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
5370 Can avoid passing a message, allowing it to be derived in the
5371 error handler (e.g., if we want to throw to the key both from
5374 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
5376 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
5377 references now have a new appearance which is more compact and
5378 also gives a clue about what the target of the reference is.
5379 By setting parameters in the print state, more fancy printing can
5380 be achieved. This is used by the (not yet commited) backtrace
5383 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
5385 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
5388 * print.c: Added #include "struct.h". Removed function
5391 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
5392 scm_iprin1. Removed prototype for scm_prlist.
5394 * arbiters.c (prinarb),
5395 async.c (print_async),
5396 debug.c (prindebugobj, prinmemoized),
5397 eval.c (prinprom, prinmacro),
5398 filesys.c (scm_fd_print, scm_dir_print),
5400 mallocs.c (prinmalloc),
5401 numbers.c, numbers.h (scm_floprint, scm_bigprint),
5402 smob.h (scm_smobfuns),
5403 srcprop.c (prinsrcprops),
5405 unif.c, unif.h (scm_raprin1, rapr1),
5406 variable.c (prin_var): Changed argument `int writing' to
5407 `scm_print_state *pstate'.
5409 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
5410 that it will be called before scm_init_print.
5412 * print.c (scm_prin1): Print states are now allocated when calling
5413 scm_prin1 and then passed around to all printing functions as an
5414 argument. A cache `print_state_pool' enables reuse of print
5416 (scm_make_print_state): New function.
5417 (scm_iprin1): Adaption to print states.
5418 (scm_iprlist): An initial "hare and tortoise" scan brings down
5419 time complexity to O (depth * N). (Better time complexity will be
5420 achieved when the printing code is completely rewritten.)
5422 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
5424 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
5425 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
5426 it gets done whether or not the cache variable has a value.
5428 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5430 Distinguish #f and ().
5431 * __scm.h: #undef SICP.
5432 * pairs.h (SCM_EOL): Delete this definition, equating it with
5434 * tags.h (SCM_EOL): Give it a new definition here; I think I found
5435 the value it used to have. Doc fixes, too.
5437 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
5439 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
5440 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
5441 Lord's implementation of structs, allowing for tail arrays as
5442 described in the manual. Also fixed some bugs. (Both the interface
5443 and the implementation should be improved.)
5445 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
5447 * print.c, print.h: Closures now print like #<procedure foo (x)>.
5448 People who whish to see the source can do `(print-enable 'source)'.
5449 Removed #ifdef DEBUG_EXTENSIONS.
5451 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5453 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
5454 integer (assuming for now accepting an integer is a good thing).
5456 * error.c, fports.c: replace use of %S in lgh_error args with %s.
5457 %S will be used instead for write'ing arguments.
5459 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
5460 asserts. fix a few other asserts.
5461 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
5462 scm_uniform_vector_ref, scm_array_set_x,
5463 scm_dimensions_to_unform_array): change args in
5464 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
5465 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
5466 scm_substring_fill_x): likewise.
5467 gsubr.c (scm_gsubr_apply): likewise.
5468 eval.c (SCM_APPLY): likewise.
5470 * eval.c (4 places): replace scm_everr with lgh_error or
5473 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
5474 scm_memory_error): new procedures.
5475 scm_everr: deleted. can use scm_wta, dropping first two args.
5476 scm_error: convert NULL subr to SCM_BOOL_F.
5478 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
5481 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
5484 * error.c, error.h: new error keys: scm_arg_type_key,
5485 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
5487 scm_wta: reimplement using lgh_error instead of scm_everr.
5489 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
5491 * gdbint.c: scm_lread now has one more argument.
5493 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
5494 scm_port_\1; Added mutator scm_set_port_filename_x (used when
5495 loading source from non-file ports, which, e. g., happens when
5496 using the Emacs interface).
5498 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
5501 * read.c: Added code for recording of positions of source code
5502 expressions; New functions: recsexpr, scm_lreadrecparen;
5503 _scm_make_srcprops --> scm_make_srcprops
5504 (scm_flush_ws): Removed updating of positions counters. This work
5505 is already done by scm_gen_getc
5507 * read.h: Added prototype for scm_lreadrecparen
5509 * print.c: Added #include "alist.h"
5511 * eval.c: Added #include "hash.h"
5513 * eq.c: Added #include "ramap.h"
5515 * options.c: Documentation fixes.
5517 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
5518 (scm_init_srcprop): Adjusted size of initial source-whash. Name
5519 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
5520 --> scm_make_srcprops
5522 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
5523 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
5524 function calls in the definition of the whash access macros.
5526 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
5528 * init.c (scm_boot_guile): Add level of indirection to
5529 scm_boot_guile_1() to ensure that stack base pointer is properly
5530 initialized. There was no guarantee that variable i was the
5531 highest/lowest variable on stack (i.e. the call frame of
5532 scm_boot_guile was not completely protected from gc).
5534 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
5536 * ports.h (scm_port_table): put back file_name, it will be used to
5537 support debugging. Undo related changes in fports.c, ioext.c,
5540 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5542 * ports.h (scm_port_table): remove file_name member for now, it seems
5544 * fports.c (scm_open_file): don't set file_name in PTAB.
5545 (prinfport): don't use file_name in PTAB.
5546 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
5547 * ports.c (scm_add_to_port_table): don't intialize file_name.
5548 (scm_port_file_name): remove for now.
5549 * gc.c (scm_gc_mark): don't mark PTAB file_name.
5551 * fports.h (scm_mkfile): prototype deleted.
5552 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
5554 * debug.c, unif.c: use scm_out_of_range instead of
5555 wta for range errors (ASSERT still needs work).
5557 * error.c, error.h (scm_out_of_range): new procedure.
5559 * error.c, error.h (scm_out_of_range_key): new key.
5561 * posix.c (scm_sync): #else was missing.
5563 * error.c, error.h: append _key to names scm_num_overflow and
5566 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
5567 of consing an empty list.
5568 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
5569 of macros, saves code and string space.
5570 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
5571 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
5572 lower case. Rename scm_syserror_m to scm_syserror_msg.
5573 error.h: prototypes for new procedures.
5575 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5577 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5579 * error.c, error.h: setup scm_num_overflow key.
5581 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5582 Remove definition of SCM_OVSCM_FLOW.
5584 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5586 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5587 explicit message and args.
5589 * error.c, error.h, __scm.h: change system_error_sym to
5592 * error.c (system_error_sym): remove leading %% from the Scheme name
5595 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5597 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5599 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5600 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5601 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5602 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5603 renamed. (These were introduced by unsupervised name
5606 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5608 * print.c: Added code for detection of circular references during
5609 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5610 a hook for printing of closures (accessible via print options).
5611 This leads to a split of calls to scm_iprin1 into two classes:
5612 elementary print operations (e. g. the code which prints a smob)
5613 still use scm_iprin1 while top level calls (like scm_display) use
5614 scm_prin1. scm_prin1 begins by clearing the data structure used
5615 to record reference information.
5617 * print.h: Added declarations of scm_prin1 and scm_prlist.
5619 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5621 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5623 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5625 * error.c (err_head): scm_iprin1 --> scm_prin1
5627 * debug.c: Adjusted header comment.
5631 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5633 * strerror.c: Doc fix.
5635 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5637 * gdbint.c (gdb_read): Now possible to run during GC.
5638 (unmark_port, remark_port): New functions.
5640 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5642 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5643 of allocating a new string object. Also, increase size by
5644 the factor 2 instead of 1.5.
5646 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5648 * __scm.h (SCM_P): Corrected to run under traditional C.
5650 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5653 * async.c: Calls to scm_sysintern corrected.
5655 * async.h (scm_async_clock): Redundant declaration removed.
5657 * continuations.c (scm_dynthrow): Redundant declaration removed.
5659 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5660 Definition typos corrected.
5662 * debug.h: Missing declarations of functions in debug.c added
5665 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5666 Missing declarations to functions in eval.c added.
5668 * filesys.c: Possibly uninitialized variable rv.
5670 * gc.h (scm_object_addr, scm_unhash_name): Missing
5671 declarations of functions defined in gc.c added.
5673 * genio.c: Possible typos str_data -> wstr_data. ???
5675 * genio.c: Possibly unintended shadowing of local variable
5676 `int c' (gotos out of scope of inner `c'). ???
5678 * init.c: Uninitialized `SCM last' may be used.
5680 * ioext.h: (scm_sys_isatty_p): Typo.
5682 * list.h (scm_list_head): Missing prototype for function in
5685 * numbers.c (scm_two_doubles): Changed from extern to static
5686 (is used only within numbers.c).
5688 * numbers.h: Repeated declarations removed.
5690 * ports.h (scm_close_all_ports_except): Declaration for the
5691 function defined in ports.c added.
5693 * posix.h: Missing declarations added.
5695 * procs.h (scm_make_subr_opt): Missing declaration added.
5697 * socket.h (scm_sys_gethost): Missing declaration added.
5699 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5701 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5702 Missing declarations added.
5704 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5706 * struct.c: Uninitialized variable `SCM answer' may be used.
5708 * unif.c (l2ra): Declaration prototype.
5710 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5711 defined in ramap.c).
5713 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5714 Redundant declarations removed (they are in ramap.h).
5716 * variable.h (scm_make_udvariable,
5717 scm_make_undefined_variable): Declaration corrected to
5718 correspond variable.c.
5720 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5721 Missing declarations added.
5723 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5725 * Makefile.in (distclean): Don't forget to delete fd.h.
5727 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5729 * fd.h.in, tags.h: Trivial cleanups.
5731 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5732 marksweep.h just declared functions from gc.c.
5733 * gc.h, libguile.h: Don't #include "marksweep.h".
5734 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5735 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5736 dependencies updated.
5738 * libguile.h: Don't #include "files.h"; it's been deleted.
5740 * files.c (scm_sys_delete_file): Moved to filesys.c.
5741 File is now empty; deleted.
5743 * filesys.c: scm_sys_delete_file is now here. Remove
5744 #if's; they seem to rely on remnants of an old portability
5745 regimen. If the problems come up again, solve them properly,
5746 using autoconf. Specifically: Don't test M_SYSV, and #define
5747 remove to be unlink if it's #defined; don't use remove just
5748 because HAVE_STDC_HEADERS is #defined.
5749 * filesys.h: Add declarations for scm_sys_delete_file.
5750 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5751 files.o, files.h, files.c, and files.x.
5752 * init.c: Don't #include "files.h", and don't call scm_init_files.
5754 Use SCM_P instead of PROTO; the latter intrudes on the user's
5756 * params.h: Deleted; definition of SCM_P moved to...
5757 * __scm.h: ... here, where it replaces PROTO macro.
5758 * libguile.h, smob.h: Don't #include "params.h".
5759 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5760 smob.h: Fix prototypes accordingly.
5761 * Makefile.in: Update dependencies.
5762 (inner_h_files): Remove params.h.
5764 * gc.c: #include "gc.h"; every module should include its header,
5765 to let the compiler cross-check the declarations against the
5768 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5769 simpos.h: #include "libguile/__scm.h".
5771 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5773 * init.c: Don't forget to #include smob.h and init.h.
5774 * Makefile.in: Dependencies updated.
5776 * smob.h: Use PROTO instead of #if __STDC__.
5778 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5780 * __scm.h: Doc fixes.
5782 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5783 <angles>; this allows `make depends' to work properly.
5785 * libguile.h: #include smob.h and pairs.h before the others; they
5786 define typedefs used by other headers.
5788 C files should #include only the header files they need, not
5789 libguile.h (which #includes all the header files); the pointless
5790 recompilation was wasting my time.
5791 * Makefile.in (all .o dependency lists): Regenerated.
5792 * libguile.h: Don't try to get a definition for size_t here...
5793 * __scm.h: Do it here.
5794 * _scm.h: Since this is the internal libguile header, put things
5795 here that all (or a majority) of the libguile files will want.
5796 Don't #include <libguile.h> here; that generates dependencies on
5797 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5798 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5799 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and
5801 * alist.c: Get "eq.h", "list.h", "alist.h".
5802 * append.c: Get "append.h", "list.h".
5803 * arbiters.c: Get "arbiters.h", "smob.h".
5804 * async.c: Get "async.h", "smob.h", "throw.h", "eval.h".
5805 * boolean.c: Get "boolean.h".
5806 * chars.c: Get "chars.h".
5807 * continuations.c: Get "continuations.h", "dynwind.h", "debug.h",
5809 * debug.c: Get "debug.h", "feature.h", "read.h", "strports.h",
5810 "continuations.h", "alist.h", "srcprop.h", "procprop.h", "smob.h",
5811 "genio.h", "throw.h", "eval.h".
5812 * dynwind.c: Get "dynwind.h", "alist.h", "eval.h".

5896 * weaks.c: Get "weaks.h".
5898 * stackchk.h: #include "libguile/debug.h",
5900 * print.h, read.h: #include "options.h", since everyone who uses
5901 either of these files will need that.
5903 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5904 anyone who uses this file will need them to define the smob
5905 printing functions. Also, get markers.h, since people will need
5906 to #define the mark functions.
5908 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5909 * ports.h: ... to here.
5911 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5912 don't rely on archaic C default type rules.
5914 * fports.h: #include "libguile/ports.h", since you need that in
5915 order to parse this.
5917 * genio.h: #include "libguile/print.h", because you need that to
5918 parse this; don't bother #including "ports.h", since print.h gets
5921 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5923 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5924 this; it's now a reference to an element of *scm_root.
5926 * debug.h: Don't #include "options.h"; the compiler won't be able
5927 to find that once the headers are installed; instead, #include
5928 "libguile/options.h".
5929 * gc.h: Same, with marksweep.h.
5930 * mbstrings.h: Same, with symbols.h.
5931 * scmhob.h: Same, with _scm.h.
5932 * smob.h: Same, with params.h.
5934 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5935 C files; there's no need for this, and it forces recompilations
5938 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5940 * error.c (scm_error): declare scm_error_callback.
5942 * error.h: prototype for scm_error_callback.
5944 * __scm.h: define lgh_error.
5945 (SCM_SYSERROR): redefine using lgh_error.
5947 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5949 * error.c (scm_error): new procedure.
5951 * error.h: prototype for scm_error.
5953 * Makefile.in (install): install scmconfig.h from the current
5954 directory, not $(srcdir).
5956 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5958 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5959 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5960 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5961 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
5962 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
5963 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,

5965 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5966 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5967 vports.h, weaks.h: #include "libguile/__scm.h", not
5968 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5969 dependencies are within libguile properly.
5971 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5973 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5974 when scmconfig.h doesn't exist.
5976 * load.c (scm_sys_try_load): Correct spelling.
5978 * feature.c (scm_loc_features): Make this static.
5980 * Makefile.in (libpath.h): Omit trailing slash from path. We
5981 shouldn't require it of users, so why put it here?
5983 Move code to initialize and search %load-path from ice-9 to C
5984 code, so we can use the load-path to find the ice-9 boot code;
5985 this makes it easier to run Guile without installing it. See
5986 corresponding changes in guile/Makefile.in.
5987 * feature.c: Move stuff concerned with the load path to load.c.
5988 (scm_compiled_library_path): Deleted.
5989 Don't #include libpath.h here.
5990 * feature.h: Don't mention scm_compiled_library_path.
5991 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5992 <sys/stat.h>, and <unistd.h> (if present).
5993 (R_OK): #define if the system hasn't deigned to.
5994 (scm_loc_load_path): New variable.
5995 (scm_init_load_path, scm_sys_search_load_path,
5996 scm_sys_try_load_path): New functions.
5997 (scm_init_load): Initialize scm_loc_load_path to point to the
5998 value cell of the Scheme %load-path variable.
5999 * load.h: Add declarations for scm_sys_search_load_path,
6000 scm_sys_try_load_path.
6001 * init.c: Call scm_init_load_path.
6002 * Makefile.in (feature.o, load.o): Dependencies updated.
6004 * load.c, load.h: Rewrite using PROTO macro.
6006 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6008 * gc.c (scm_cellp): New function: C predicate to determine if an
6009 SCM value can be regarded as a pointer to a cell on the heap.
6011 * gc.h: Added declaration of scm_cellp.
6013 * gdb_interface.h: New file: The GDB interface header from the GDB
6016 * gdbint.c: New file: GDB interface.
6018 * gdbint.h: New file: GDB interface.
6020 * libguile.h: Added #include <libguile/gdbint.h>.
6022 * init.c (scm_boot_guile): Added scm_init_gdbint.
6024 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
6025 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
6026 found if object files and source are kept separate).
6028 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
6030 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
6032 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
6034 * configure.in: Don't substitute the values of TCL_SRC_DIR and
6035 TK_SRC_DIR; they're not relevant any more.
6037 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
6038 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
6040 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
6042 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
6043 search path, so we can find the <libguile/MUMBLE.h> headers.
6045 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
6047 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
6048 implicit in the .c.o rule.
6049 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
6052 Put the library path in a header file, instead of passing it on
6053 the command line in every compilation.
6054 * Makefile.in (libpath.h): New target.
6055 (feature.o): Depend on libpath.h.
6056 (clean): Delete libpath.h.
6057 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
6058 * feature.c: ... #include "libpath.h" here.
6059 * .cvsignore: Ignore libpath.h.
6061 Don't install the unwashed masses of Guile header files in the
6062 main #include path; put most of them in a subdirectory called
6063 'libguile'. This avoids naming conflicts between Guile header
6064 files and system header files (of which there were a few).
6065 * Makefile.in (pkgincludedir): Deleted.
6066 (innerincludedir): New variable; this and $(includedir) are enough.
6067 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
6068 (installed_h_files): Divide this up. Now this variable lists
6069 those header files which should go into $(includedir) (i.e. appear
6070 directly in the #include path), and ...
6071 (inner_h_files): ... this new variable says which files appear in
6072 a subdirectory, and are referred to as <libguile/mumble.h>.
6073 (h_files): List them both.
6074 (install): Create innerincludedir, not pkgincludedir. Put
6075 the installed_h_files and inner_h_files in their proper places.
6076 (uninstall): Corresponding changes.
6077 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
6078 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
6079 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
6080 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
6081 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
6082 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
6083 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
6084 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
6085 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
6086 vports.h, weaks.h: Find __scm.h in its new location.
6087 * __scm.h: Find scmconfig.h and tags.h in their new locations
6088 (they're both "inner" files).
6090 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
6092 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
6094 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
6096 * posix.c: Doc fixes.
6098 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
6100 * socket.c: Don't include a prototype for inet_aton; just use a
6101 K&R style declaration, to avoid warnings but minimize the chance
6102 of conflicts with the system.
6104 On NextStep, <utime.h> doesn't define struct utime, unless we
6105 #define _POSIX_SOURCE before #including it.
6106 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
6107 * acconfig.h: New comment text for above CPP symbol.
6108 * configure.in: Call it.
6109 * posix.c: #define _POSIX_SOURCE if it seems necessary.
6111 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
6113 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
6114 testing for __EMX__.
6116 * posix.c: #include <libc.h>, if it exists.
6118 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
6119 don't even know if the latter exists.
6121 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
6122 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
6123 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
6125 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
6127 (scm_init_posix): Use them when initializing the Scheme constants
6130 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6132 * Makefile.in (libdir, includedir, bindir): Use the
6133 autoconf-supplied values, instead of deriving them ourselves.
6134 (pkgincludedir, datadir, pkgdatadir): New variables.
6135 (install, uninstall): Put the header files in a special
6136 subdirectory, not in the main search path.
6138 * Makefile.in (ALL_CFLAGS): Provide the proper value for
6139 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
6141 * Makefile.in (IMPLPATH): Deleted; never used.
6143 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
6144 on the Tcl/Tk source any more.
6145 (INCLUDE_CFLAGS): Remove references to the above.
6147 * Makefile.in (version.o): Corrected dependencies.
6149 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
6151 * libguile.h: #include "version.h"
6153 * init.c (scm_boot_guile): Call scm_init_version.
6154 * gscm.c (gscm_run_scm): Call scm_init_version.
6156 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
6157 GUILE_VERSION): AC_DEFINE these.
6158 (acconfig.h): #undef the above symbols.
6160 * Makefile.in (libobjs): Add version.o.
6161 (installed_h_files): Add version.h.
6162 (c_files): Add version.c.
6163 (gen_c_files): Add version.x.
6164 (version.o): New rule.
6165 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
6166 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

6174 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
6175 weaks.o): Add version.h to dependency lists.
6176 (markers.o): Remove duplicate rule.
6178 * version.h: New file.
6180 * version.c: New file.
6182 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6184 * symbols.c (scm_strhash): scm_downcase is now a function, not an
6185 array; use it appropriately. Since GCC is quite happy to
6186 subscript functions, it never warned us about this; we should use
6187 -Wpointer-arith in the future. I guess we never tested
6190 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6192 * socket.c: Doc and copyright fixes.
6194 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6196 * debug.c: Fixed and improved gdb support.
6198 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6200 * socket.c: Added declaration of inet_aton to avoid compiler
6201 warning. (Hope this solution is correct.)
6203 * stime.c: Added declaration of ftime. (This is missing in
6206 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
6208 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
6210 * Makefile.in (c_files): add strerror.c.
6212 * strerror.c: new file from Emacs' sysdep.c.
6213 maybe configure should also check for sys_errlist.
6215 * configure.in (AC_REPLACE_FUNCS): add strerror.
6217 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6219 * debug.c (scm_init_debug): Added initialization for
6220 scm_evaluator_traps.
6222 * debug.h, debug.c: Various name changes.
6223 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
6224 "debug-options-interface". See commentary in options.c.
6226 * options.h, options.c: Options now have documentation strings.
6227 Also added a long explanatory commentary.
6229 * eval.c, print.h, print.c, read.h, read.c: Modifications to
6232 * gscm.c, init.c, root.c, throw.c: Bug fixes:
6233 last_debug_info_frame is now updated in all cases.
6235 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
6238 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6240 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
6241 Added option STACK_CHECKING.
6243 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
6245 * Makefile.in: Added {debug,options,srcprop}.{h,c}
6247 * __scm.h: Removed symbols for debugging support.
6249 * acconfig.h: Added symbols for debugging support.
6251 * configure.in: Added user option for debugging support.
6252 --enable-debug will include the debugging code into libguile.a.
6254 * continuations.c (scm_make_cont): Enlarged the #if 0 around
6255 scm_relocate_chunk_to_heap.
6257 * debug.c: New file: low-level debugging support. It also
6258 includes support for debugging with gdb. (The extensions to gdb
6259 are written by Per Bothner at Cygnus.)
6261 * debug.h: New file: low-level debugging support.
6263 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
6264 argument pairs. Extensive modifications to the debugging
6265 evaluator. Added "SECTION:" commentaries to clarify what happens
6266 when, during double compilation. Renamed EVALIMP --> EVALIM.
6267 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
6268 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
6269 the beginning of the file. New procedure: scm_unmemocopy.
6270 Added some global state variables needed by the debugging
6271 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
6272 check_entry, check_apply, check_exit, debug_options and
6273 evaluator_traps. New acro: undefine.
6275 * eval.h: Renamed EVAL --> XEVAL.
6277 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
6278 --> scm_make_weak_key_hash_table.
6280 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
6281 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
6283 * libguile.h: Conditionally include debug.h
6285 * objprop.c (scm_object_properties, scm_set_object_properties_x):
6286 scm_object_properties shouldn't return handle. `handle' now gets
6287 initialized in scm_set_object_properties_x. scm_object_properties
6288 doesn't any longer create an entry in scm_object_whash.
6290 * options.c: New file: handling of run time options.
6292 * options.h: New file: handling of run time options.
6294 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
6296 * print.c: New procedure: scm_print_options
6298 * print.h: Defines for print options.
6300 * read.c: New procedure: scm_read_options
6302 * read.h: Defines for reader options.
6304 * root.h: Added scm_source_whash among scm_sys_protects.
6306 * srcprop.c: New file: source properties.
6308 * srcprop.h: New file: source properties.
6310 * throw.c (jbsmob): Jump buffers are now correctly allocated.
6311 (Bug found by A. Green.)
6313 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6315 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6317 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
6319 * libguile.h: #include "objprop.h"; I guess this was forgotten.
6321 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
6322 and should be called by the final client.
6324 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
6326 * gc.h: Use the PROTO macro when declaring functions.
6327 * gc.c: Use the PROTO macro when declaring static functions.
6328 Remove the CPP hair around function definitions.
6330 * gc.c (scm_init_storage): Initialize scm_asyncs.
6332 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
6333 preprocessor symbol; "__scm.h" is where it might get #defined.
6334 * __scm.h: Similar: #include <scmconfig.h> before testing
6337 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
6339 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
6341 * init.c (scm_boot_guile): Add init_func argument; call
6342 (*init_func) instead of calling scm_appinit; it's ucky to
6343 hard-code names for the user's procedures.
6344 * init.h (scm_boot_guile): Adjust declaration.
6346 * __scm.h (PROTO): New macro, for declaring functions with
6349 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
6350 eliminate all the __STDC__ conditionals.
6351 (scm_boot_guile): Add declaration.
6352 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
6353 Remove __STDC__ conditionals around function definitions; the
6354 declarations in init.h will provide the same information, more
6357 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
6358 complain about it in the error message; the error message is
6359 adequate without that note, and there's nothing the user can do
6362 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
6364 * Makefile.in (ancillary): Drop def.sed.
6366 * posix.c (scm_init_posix): Use numeric values, rather than
6367 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
6368 F_OK. The symbols aren't available on some systems, and I'm
6369 pretty sure their values are fixed by common widespread practice.
6370 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
6372 More functions unavailable on some systems.
6373 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
6374 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
6376 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
6377 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
6378 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
6379 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
6380 stub that signals an error as the #else.
6382 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
6384 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
6386 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
6388 * unif.c: include ramap.h.
6390 * read.c (endif): case_insensative_p renamed case_insensitive_p.
6392 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
6394 * ports.c: include sys/ioctl.h.
6396 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
6398 * configure.in: check for sys/ioctl.h.
6400 * ports.c: include <malloc.h> not "malloc.h".
6402 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6404 * fports.c: remove ttyname and tmpnam declarations.
6406 * posix.c: fewer ttyname declarations.
6408 * fports.c: include <string.h> not "string.h".
6410 * init.c, ioext.c: include string.h and unistd.h.
6412 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6414 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
6415 genio.c, simpos.c, vports.c: include string.h.
6417 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
6419 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
6421 (scm_addr_buffer_size): change type from scm_sizet to int.
6422 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
6423 from scm_sizet to int.
6425 * error.c: include unistd.h.
6427 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
6430 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
6432 * __scm.hd, def.sed: deleted.
6434 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
6436 Changes for NeXT, suggested by Robert Brown.
6437 * configure.in: Call AC_TYPE_MODE_T.
6438 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
6439 NeXT. Put header file list in alphabetical order.
6440 * configure, scmconfig.h.in: Regenerated.
6441 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
6443 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
6446 * acconfig.h: New file, providing documentation for the CPP
6447 symbols defined in configure.in
6448 * acconfig-1.5.h: Removed; superceded by the above.
6450 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
6452 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
6454 * fports.c (scm_open_file): don't return #f, throw error.
6456 * ioext.c (fileno): renamed from %fileno.
6457 (soft-fileno): deleted.
6459 * ports.c (scm_port_revealed): don't need to check for -1 from
6461 (scm_set_port_revealed_x): return unspecified, not #f.
6463 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
6465 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
6467 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
6469 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
6471 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6473 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
6474 This is necessary on Ultrix, and doesn't hurt portability.
6476 * Makefile.in (dist-dir): New target, implementing a new dist system.
6477 (installed_h_files): Put in alphabetical order.
6478 Remove duplicate entries for markers.h and unif.h.
6479 (c_files): Remove duplicate entries for markers.c.
6480 (ancillary): Renamed from anillery; all uses changed. Remove
6481 PLUGIN; it's a directory, and needs special treatment in dist-dir.
6482 Remove all the ../doc/* files; doc/Makefile.in handles that.
6484 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
6486 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
6487 every if must have an else, or else the whole command has a
6488 non-zero exit code whenever the if's condition is false.
6490 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
6492 * posix.c: include string.h.
6494 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6496 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
6499 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
6500 Remove leading % from scheme names.
6501 Do not return error values, call SCM_SYSERROR or similar.
6503 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
6505 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
6507 * struct.c (scm_init_struct): new file.
6509 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
6511 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
6512 (scm_list_head): added list-head for rapidly chopping argument
6513 lists off of longer lists (and similar).
6515 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
6517 * objprop.c (scm_object_property): assq the cdr of the whash
6518 handle for obj, not the handle itself.
6520 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
6522 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
6523 weak hash tables last of all marking to avoid an obscure gc bug.
6524 WARNING: circular lists stored in a weak hash table will hose us.
6526 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
6528 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
6529 new functions similar to scm_substring_move_left_x and
6530 scm_substring_move_right_x.
6532 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
6534 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
6537 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
6539 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
6541 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
6543 * strports.c (scm_strprint_obj): convenience function. C for
6544 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
6546 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
6547 removed to a separate library
6549 * init.c (scm_boot_guile): copied from guile-tcl.c.
6550 Initialization specific to tcl interpreters removed.
6552 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
6554 * ports.c (scm_ports_prehistory): size malloced here doesn't
6555 matter so long as it is non-0 (got rid of "* 4").
6557 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
6559 * gscm.h: gscm_mkarray eliminated (presumably was not being used
6560 since its definition was bogus).
6562 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
6564 * mallocs.[ch]: back again (for rx at least).
6566 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
6568 * ports.c: removed functions relating to the mapping between ports
6569 and descriptors. (That stuff is unix-specific and should be collected
6570 in a separate library).
6572 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
6573 (Tom Mckay@avanticorp.com)
6575 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
6577 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
6578 handled correctly (SCM_FREEP was applied to them) -- test for
6579 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
6580 being overwritten with #f. (brown@grettir.bibliotech.com)
6582 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
6584 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
6585 for a specific symbol or for all symbols.
6587 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
6589 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
6590 keys and weak values confused).
6592 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
6594 * list.c (scm_last_pair): map '()=>'()
6596 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
6598 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
6599 Generalized assoc and hash-table functions.
6600 Factored pairs.c into multiple files.
6602 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
6604 * gscm.c (gscm_run_scm): got rid of objprop.
6606 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
6608 * genio.c (scm_getc):
6609 NOTE: fgetc may not be interruptable.
6611 * procprop.c (scm_stand_in_scm_proc):
6612 NOTE: don't use a alist here.
6613 (scm_set_procedure_properties_x): fix type checking throughout this file.
6615 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
6617 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
6618 after freeing part of the port table.
6620 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
6622 * strports.c (scm_mkstrport):
6623 * vports.c (scm_make_soft_port): allocate a port table entry
6624 (possibly triggering gc) before setting the tag of the corresponding
6627 * pairs.c (scm_delq_x): never throw an error.
6629 * vectors.c (scm_make_vector): made the default vector fill argument
6630 into '() (much more useful than the previous value, "#unspecified")
6632 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
6634 * ports.c (scm_add_to_port_table): Added fields
6635 to port table entries: file_name, line_num, col.
6636 Update these in open_file, gen_getc and gen_ungetc.
6637 Added procedures to access those fields.
6639 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
6641 * procs.c (scm_make_subr_opt): new entry point for making
6644 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
6646 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
6648 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
6650 * numbers.c (scm_exact_p): This function no longer
6651 implements "integer?".
6653 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
6655 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
6656 (scm_gc_stats): return an assoc of useful data. Replaces "room"
6657 and the stats reporting formerlly built into repl.
6659 * repl.[ch]: removed.
6660 GC statistics keeping moved to gc.c.
6661 Other statistics keeping can be done from Scheme.
6662 REPLS are now written in Scheme.
6664 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
6666 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
6667 conservatively marked objects).
6669 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
6671 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
6673 * feature.c (scm_compiled_library_path): moved here from repl.c.
6674 This file is for stuff relating specifically to Scheme libraries
6677 * eval.c (scm_m_define): don't give warning about redefinition, don't
6680 NOTE: this should throw a resumable exception with parameters --
6681 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
6683 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
6685 * error.c: scm_warn eliminated.
6687 * read.c (scm_lreadr): extra right paren gets an error, not a warning.

6690 lose exit_report, growth_mon.
6692 * gscm.c: got rid of verbosity functions.
6694 Tue Feb 20 00:19:10 1996 Tom Lord <lord@beehive>
6696 * throw.c (scm_ithrow): guard against the bad-throw hook changing
6697 between the call to procedurep and use.
6699 * error.c (scm_everr):
6701 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
6704 * strports.c: don't reveal the port's string to the caller
6705 because it changes size.
6707 (stputc stwrite): check/change the strings length with interrupts
6710 * objprop.c (scm_set_object_property_x &c): use the generic
6711 hashing functions and be threadsafe.
6713 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
6714 (per suggestion jaffer@gnu.ai.mit.edu).
6716 * mbstrings.c (scm_multi_byte_string): guard against argument list
6719 * strings.c (scm_make_string): loop cleanup
6721 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
6724 * weaks.c (scm_weak_vector): guard against argument list
6727 * variable.c (scm_builtin_variable): check for/make a built-in
6730 * vectors.c (scm_vector): while filling the new array,
6731 guard against a list of fill elements that grows after
6732 the vector is allocated.
6734 * hashtab.c -- new file: general hash table
6735 functions. hash, hashq, hashv, hashx.
6737 * tags.h: made wvect an option bit of vector.
6739 Mon Feb 19 09:38:05 1996 Tom Lord <lord@beehive>
6741 * symbols.c: made the basic symbol table operations atomic.
6743 * root.c &c.: collected stack-specific global state.
6744 linum/colnum etc *should* be port-specific state.
6746 * struct.c (scm_init_struct): init the first struct type during
6747 initialization to fix a race condition.
6749 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
6750 object, not in a global.
6751 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
6753 * throw.c (_scm_throw): Pass throwval on the stack, not in a global
6754 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
6756 * *.[ch]: namespace cleanup. Changed all (nearly) exported CPP
6757 and C symbols to begin with SCM_ or scm_.
6759 Sun Feb 18 15:55:38 1996 Tom Lord <lord@beehive>
6761 * gsubr.c (scm_gsubr_apply): statically allocate the
6762 array of arguments (bothner@cygnus.com).
6764 Sat Feb 17 20:20:40 1996 Tom Lord <lord@beehive>
6766 * scmsigs.c: Simplified to use async rountines.
6768 * async.c: New support for interrupt handlers.
6770 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
6772 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
6773 set the multi_byte flag correctly in symbols. This is wrong.
6774 intern_obbary_soft and msymbolize should take an extra parameter.
6775 Also, weird multibyte symbols don't print correctly.
