1 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * coop-threads.c, threads.h (scm_spawn_thread): New function.
4 Can spawn a thread from application C code.
6 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
8 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
9 gh_doubles2scm): New functions.
11 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
13 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
14 commented-out version of gh_eval_str()
16 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
18 * socket.c (scm_bind): free soka after use.
20 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
22 * stime.c (tzvar): new variable.
23 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
24 avoid memory leaks when allocating.
26 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
28 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
31 * gc.c, tags.h: Doc fixes.
33 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
35 * eval.c (macro-eval!): Removed. This function was a design bug.
36 It allowed memoized code to leak out to the scheme level. Most
37 things that you could do with `macro-eval!' can be done with
40 1997-12-20 Tim Pierce <twp@skepsis.com>
42 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
43 scm_fgets now depends on ftell(3) to know how many bytes were
46 1997-12-15 Tim Pierce <twp@skepsis.com>
48 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
51 1997-12-13 Tim Pierce <twp@skepsis.com>
53 Make %read-line more suitable for implementing read-line efficiently.
54 * ioext.c (scm_read_line): Strip the terminating newline from a
55 string, and return a cons of the string and its terminator.
57 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
58 of the string that is read is stored in this memory location.
59 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
60 * genio.c, genio.h (scm_do_read_line): Update caller.
61 * ports.h (scm_ptobfuns): Update typedef.
62 * fports.c (scm_fptob, scm_pipob): Update struct.
64 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
66 * filesys.c (set_element): Return file descriptor.
67 (fill_select_type): Return the highest file descriptor.
68 (scm_select): Tell select about the highest file descriptor. On
69 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
70 Therefore the extra overhead for calculating the maximum fd seems
71 to be more than compensated. Is this correct? In any case,
72 scm_internal_select will be much faster with this info.
73 (scm_select, fill_select_type, set_element): Don't accept any kind
74 of object in the file descriptor list or vector.
76 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
78 * iselect.c (finalize_fd_sets): Bugfix.
80 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
82 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
83 when using scm_internal_select (since we might switch to another
86 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
88 * simpos.c (scm_system): always define: use sysmissing if not
89 available. Check for HAVE_SYSTEM instead of _Windows (does
90 Windows lack system or does it have an unusable one?).
91 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
92 Let the argument be optional: if not supplied, call system(NULL).
94 * ports.c (scm_close_port): relax the type check from OPPORTP to
95 PORTP; closing a closed port is allowed.
97 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
99 * fports.c (scm_fgets): Return if the last char in a chunk is
100 newline. When fgets returns a string whose length is `size-1', it
101 is ambiguous whether a whole line was retrieved, so we must check
102 explicitly whether a line terminator is present.
104 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
106 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
107 before taking the CDR. (Thanks to Harald Meland.)
109 * filesys.c (scm_stat): Slightly optimized.
111 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
113 * ports.c (scm_close_port): Make sure the port is open before
116 * guile-snarf.in: Pass args through to gcc in a way that preserves
117 whitespace boundaries. (Thanks to Greg Badros.)
119 1997-12-02 Tim Pierce <twp@skepsis.com>
121 * stacks.c (scm_frame_procedure): Reverse the logic in the return
122 statement. (Thanks to Doug Evans for pointing this out.)
124 1997-12-01 Tim Pierce <twp@skepsis.com>
126 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
128 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
130 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
131 errno macro expansion of this field name. (errno is a C
132 preprocessor macro on some systems.)
134 1997-11-29 Tim Pierce <twp@skepsis.com>
136 * iselect.c: Doc fix.
138 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
140 * init.c (scm_start_stack): Removed initialization of
141 scm_the_last_stack_var.
143 * backtrace.h: Declare scm_the_last_stack_var.
145 * backtrace.c: Define scm_the_last_stack_var.
147 * root.c (mark_root): Don't mark the_last_stack_var.
149 * root.h (scm_root_state): Removed the_last_stack_var.
151 * throw.c: Added #include "fluids.h"
152 (ss_handler): `the-last-stack' is now a fluid.
154 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
155 --> the_last_stack_fluid.
157 * backtrace.c: Added #include "fluids.h"
158 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
159 (scm_backtrace): `the-last-stack' is now a fluid.
161 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
162 after scm_init_fluids.
164 1997-11-28 Tim Pierce <twp@skepsis.com>
166 * iselect.c: #ifdef USE_THREADS around thread-related includes.
168 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
169 DLSYM_ADDS_USCORE to decide whether to add an underscore.
171 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
173 * iselect.c (coop_next_runnable_thread,
174 coop_wait_for_runnable_thread): Disable interrupts so that no
175 async is executed before a potential error_revive.
176 (scm_internal_select): Disable interrupts during the parts of the
177 code which manipulate the sleep queue and the file descriptors.
179 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
181 * Makefile.am: Added iselect.c and iselect.h.
183 * coop.c (coop_qinit): Initialize fields used by
185 (coop_qget, coop_qget, coop_tmp_queue): Made global.
186 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
187 replacement in iselect.c.
188 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
189 coop_join): If GUILE_ISELECT enabled, use
190 coop_wait_for_runnable_thread instead of
191 coop_next_runnable_thread.
192 (usleep, sleep): New replacements for system functions if
193 GUILE_ISELECT is enabled.
195 * coop-threads.h: Declare coop_wait_for_runnable_thread.
197 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
199 * filesys.c: Added #include "iselect.h". Moved FD-macros to
200 iselect.h. Implement Scheme level `select' using
201 scm_internal_select. (See NEWS.)
203 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
205 * init.c: Call scm_init_iselect.
207 * iselect.h, iselect.c: New files. Implements
208 scm_internal_select. (See NEWS.)
210 1997-11-27 Tim Pierce <twp@skepsis.com>
212 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
213 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
214 and scm_must_free, since ultimately the string returned will be copied
215 by scm_makfrom0str anyway. Also, read any characters that may have
216 been pushed onto the port with scm_ungetc.
217 * ports.c (scm_generic_fgets): Same as for scm_fgets.
218 * ioext.c (scm_read_line): Free string after Guilifying it.
219 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
221 1997-11-26 Anthony Green <green@hoser.cygnus.com>
223 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
225 * gh.h: Safely wrap prototypes for c++ usage.
227 1997-11-25 Mark Galassi <rosalia@cygnus.com>
229 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
230 gh_repl (argc, argv).
232 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
234 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
235 and to invoke scm_shell().
236 (gh_launch_pad): took out the loading of boot-9.scm from here,
237 since it is probably best to let the user control that. In fact,
238 gh_repl() now invokes scm_shell() which does that.
240 1997-11-23 Mark Galassi <rosalia@cygnus.com>
242 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
245 1997-11-22 Tim Pierce <twp@twp.tezcat.com>

248 yesterday's underscore patch. (Thanks to Marius Vollmer for
251 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
253 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
254 DLSYM_ADDS_USCORE is not defined.
256 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
258 * gh_data.c (gh_uniform_vector_length):
259 (gh_uniform_vector_ref): started implementing the uniform types in
262 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
264 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
265 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
267 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
269 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
270 configure.in was changed).
272 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
274 * Makefile.am (modinclude_HEADERS): Include readline.h here.

277 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
279 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
280 OPORT is an `open' port, not an output port.

283 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
284 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
285 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
286 scm_close_port, scm_port_line, scm_set_port_line_x,
287 scm_port_column, scm_set_port_column_x, scm_port_filename,
288 scm_set_port_filename_x, scm_port_mode,
289 scm_close_all_ports_except, scm_set_current_output_port,
290 scm_set_current_error_port): Likewise
291 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
292 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
294 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
295 * backtrace.c (display_backtrace_body): Likewise
296 * fports (scm_setvbuf): Likewise
297 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

302 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
304 Minor problems with substring-related tag changes.
305 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
306 exactly what we want to leave in to detect substrings.
307 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
308 * tags.h: Fix diagrams and comments describing the S tag bit;
309 remove vestigial remarks about the D tag bit.
310 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
311 * strings.c: Formatting tweaks.
313 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
314 variable first; then SCHEME_LOAD_PATH, with a warning message.
315 (scm_parse_path): New function.
316 * script.c: Doc fixes.
318 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
320 Readline support, from Daniel Risacher.

332 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
334 * gh_data.c (gh_vector_set_x): changed name to make it consistent
335 with the ! -> _x mapping when going from Scheme to C.
337 1997-10-19 Mark Galassi <rosalia@cygnus.com>
347 (gh_assoc): added these gh_ functions implemented as macros.
349 * gh_predicates.c (gh_null_p):
350 (gh_string_equal_p): added these two missing predicates.
352 * gh_list.c (gh_append):
357 (gh_set_cdr_x): added these routines as I go through and try to
358 complete the picture R4RS functions that should be mirrored in the
361 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
363 * tags.h (scm_tc7_substring): Changed the comment and code to
364 conform with the changes below. Folks! We have suddenly two new
365 free tc7 codes!!! Jummy, jummy!
367 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
369 * Makefile.in: Rebuilt.

394 Don't include "mbstrings.h".
395 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
396 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
398 Don't include "mbstrings.h".

400 (SCM_SYMBOL_SLOTS): Define as 4.
401 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.

406 ("gen"-less) I/O function names.
407 * ports.c (scm_add_to_port_table): Don't set port's
409 * ports.h (scm_port_representation_type): Removed.
410 (scm_string_representation_type): Removed.
411 (struct scm_port_table ): Removed representation field.
412 (SCM_PORT_REPRESENTATION): Removed.
413 (SCM_SET_PORT_REPRESENTATION): Removed.

429 * gh_test_c.c (c_vector_test): some improvements on the vector
432 * gh.h (gh_vector): this used to exist but do the wrong thing.
433 Now it (almost) does the right thing, though it takes a list
434 instead of the individual arguments. I need to see how it could
436 (gh_list_to_vector): added this function as a macro. Corresponds
437 to Scheme's (list->vector ...).
438 (gh_vector_to_list): added this function as a macro. Corresponds
439 to Scheme's (vector->list ...).
441 * gh_data.c (gh_vector_ref): renamed from gh_vref to
442 gh_vector_ref, so that it resembles the Scheme routines more.
443 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
444 resembles the Scheme routines more.
445 (gh_make_vector): this used to be (stupidly) called gh_vector().
446 This is the right name, since it does the same thing as the Scheme
447 (make-vector ...) procedure.
449 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
451 * ports.h: #include "libguile/print.h"

464 gh_int2scmb(), which is now tagged as obsolete.
466 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
468 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
469 macros should by convention not test for NIMPness.)
470 (SCM_COERCE_OPORT): Adjust indentation.
472 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
473 SCM_NIMP test before SCM_PRINT_STATE_P.
475 * struct.c, struct.h, gc.c: Renamed:
476 scm_struct_i_layout --> scm_vtable_index_layout
477 scm_struct_i_vcell --> scm_vtable_index_vcell
478 scm_struct_i_vtable --> scm_vtable_index_vtable

483 printing: Also output hex code of vtable so that type identity
484 will be indicated as well.
485 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
486 Removed struct_printer_var; Removed struct-vtable-offset;
487 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
488 vtable-offset-user): New constants.
490 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
491 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
492 If this slot contains a procedure, use that to print structures of
493 the type represented by this vtable.
495 * print.c (scm_iprin1): Don't print arguments of macro
496 transformers. (They are always: exp env.); Bugfix: Unmemoize
497 transformer source with correct environment.
499 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
501 Streamlining of call-with-dynamic-root:
503 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
504 there is now only one catch.
505 (cwdr_outer_body): Removed.
506 (cwdr_handler): New function.
507 (scm_internal_cwdr): New function to perform the function of cwdr
508 but take args that are more useful to C code. Also, the handler
509 is now invoked *outside* of the new dynamic root, like the docs
510 say. We no longer have to catch absolutely all errors, the caller
511 is responsible for using a handler that does not throw, if he
513 (cwdr): Reimplemented in terms of scm_internal_cwdr.
514 * root.h (scm_internal_cwdr): New prototype.
516 Even more but risky streamlining:
518 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
519 allocation of the jumpbuf of a root continuation. The changes
520 below are controlled by it. They are now deactivated.
521 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
522 the JMPBUF of the scm_rootcont to NULL before returning.
524 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
525 when they are non-NULL.
526 (scm_gc_mark): Likewise, mark only when non-NULL.
528 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
529 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
531 * gc.c (scm_done_malloc): New function.
532 gc.h (scm_done_malloc): New prototype.
534 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
535 (struct scm_print_state) [revealed]: New field.
536 (scm_print_state_vtable): Make visible to the outside world for
537 type checking purposes.
538 (scm_valid_oport_value_p): New prototype.
540 * print.c (scm_valid_oport_value_p): New function to check whether
541 a certain value is acceptable as a port argument.
542 (scm_print_state_vtable): New variable.
543 (scm_free_print_state): Set `revealed' field to false.
544 (scm_iprin1): Call user supplied closure printer with
545 scm_printer_apply. Print in the traditional way when there isn't
546 one or when it returns #f.
547 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
548 Accept a port/print-state pair in addition to just a port.
549 (scm_prin1): Don't return the print_state to the pool when it has
551 (scm_printer_apply): Set `revealed' field of print_state to true.
552 (scm_init_print): Set scm_print_state_vtable.
553 (print_state_fluid, print_state_fluid_num): Removed.
555 * throw.h (scm_handle_by_proc_catching_all): New prototype
556 throw.c (scm_handle_by_proc_catching_all): New function
558 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
560 * Makefile.in: Regenerated with automake 1.2c.
562 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
564 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
565 was looping endlessly.
567 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
569 * strports.c (scm_eval_string): Don't close the port.
571 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
572 former returns a nice normal integer. (Thanks to Daniel
575 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
577 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
578 makefile variable as a build parameter called LIBS. The
579 build-guile program will use this, for the time being.
580 * Makefile.in: Regenerated.
582 Thanks to Shiro Kawai:
583 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
584 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
587 * Makefile.in: Regenerated with automake 1.2a.
589 * script.c (scm_compile_shell_switches): If we hit the -c or --
590 arguments, don't set the car of (command-line) to scm_usage_name,
591 the prettified name of the guile executable; give it the full
592 path, the way shells usually handle $0.
594 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
596 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
597 Scheme-level name `array-map' and renamed `serial-array-map' to
600 * backtrace.c: Introduced exception handlers which now enclose
601 `display-error' and `display-backtrace' so that error reporting
602 won't get into infinite loops if an error occurs during displaying
603 of the error. This can very easily happen with user supplied
604 print call-back routines.
606 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
608 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
609 the names `serial-array-map' and `array-map' should be removed.)
611 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
613 * init.c (scm_boot_guile_1): Added scm_init_objects ().
614 Added #include "objects.h"
616 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
617 Add #include "feature.h".
619 * Makefile.am (libguile_la_SOURCES): Added objects.c.
620 (modinclude_HEADERS): Added objects.h.
622 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
623 This test is needed at many places in the code and should be
624 abstracted. (Motivated by the need of this test in libguiletk.)
626 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
627 (scm_eval_string), load.c (scm_primitive_load,
628 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
629 Use SCM_EOF_OBJECT_P.
631 * eval.c (scm_init_eval): Add feature `delay'.
633 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
637 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
639 * list.h (SCM_LISTn): New macros. Make list creation in C code
640 prettier. The idea comes from STk.
642 * sequences.h, sequences.c, append.h, append.c: Removed. These
643 files implemented non-R4RS operations which would encourage
644 non-portable programming style and less easy-to-read code.
646 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
649 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
650 sequences.h, #include append.h.
652 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
655 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
657 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
659 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
661 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
663 * eval.c: Added #include "objects.h"
665 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
668 * smob.c (scm_smob_prehistory): Create two objectsmobs with
669 adjacent smob numbers.
671 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
673 * procprop.h: Added declaration of scm_i_inner_name.
675 * gsubr.c: New global symbol scm_i_inner_name.
677 * debug.c (scm_procedure_name): Try procedure property
678 `inner-name' if `name' fails.
680 * print.c (scm_iprin1): Use scm_macro_name.
682 * eval.c (scm_m_define): Give names to macros as well; Only the
683 first top-level definition gives a procedure/macro a name.
684 Otherwise confusing names can turn up in backtraces.
685 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
686 `name'; Give names to macros as well.
688 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
689 (scm_macro_transformer): Use SCM_CLOSUREP instead of
692 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
694 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
696 (prinmacro): Removed. The code has been moved/merged into print.c
697 in order to decrease code redundancy. We want macros to print in
698 a way equivalent to procedures, and it would be silly to duplicate
699 the required code. (We don't want to maintain two places.)
700 (macrosmob): Print field is now a NULL pointer.
702 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
703 scm_macro_transformer): New prototypes.
704 (scm_tc16_macro): Declared.
706 * * print.c (scm_iprin1): Added code for printing of macros. Macros
707 are now printed in a way equivalent to procedures.
709 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
711 * procs.h (scm_closure_p): Added declaration.
713 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
715 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
716 Shouldn't pass "heap" as the subr name.
718 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
720 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
721 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
722 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
723 gh_equal_p): Use SCM_NFALSEP, instead of testing against
724 SCM_BOOL_T. Any non-false value is true.
726 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
728 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
729 scm_gensym): Added prototypes.
731 * symbols.c (scm_gensym): New function. This will speed up
732 certain types of applications (such as macro systems) which
733 generate lots of symbols.
735 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
737 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
739 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
741 * unif.c (scm_shap2ra): tighten the checking of the array dimension
742 specifier, since (2) or (2 . 3) would cause SEGV.
743 (scm_transpose_array): more argument checking fixes.
745 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
747 * Makefile.in: Regenerated.
749 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
751 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
753 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
755 * error.c, error.h (scm_error_callback): Removed (see NEWS).
757 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
759 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
760 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
763 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
764 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
765 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
766 scm_array_p, scm_array_rank, scm_array_dimensions,
767 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
768 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
769 scm_array_prototype): Added case scm_tc7_wvect.
771 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
773 * errno.h: prototype for scm_strerror.
774 * error.c (scm_strerror): new procedure.
776 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
778 * list.c (scm_list_append_x): Allow non-pair as last argument.
779 This is consistent with the R4RS append and is probably the
780 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
782 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
784 * stime.h: prototype for scm_times.
785 * stime.c (scm_times): new procedure.
786 * ioext.c (scm_fseek): if the first argument is a file descriptor
788 (scm_ftell): if the first argument is a file descriptor call lseek
790 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
791 * filesys.c (scm_chmod): if the first argument is a file descriptor,
793 (scm_chown): if the first argument is a port or file descriptor,
795 (scm_truncate_file): new procedure.
796 Add DEFER/ALLOW INTS to a few other procedures.
797 (scm_fsync): new procedure.
798 (scm_open_fdes): new procedure.
799 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
801 (scm_fcntl): the first argument can now be a file descriptor. The
802 third argument is now optional.
804 * posix.c (scm_execl, scm_execlp): make the filename argument
805 compulsory, since omitting it causes SEGV.
806 (scm_sync): return unspecified instead of #f.
807 (scm_execle): new procedure.
808 (environ_list_to_c): new procedure.
809 (scm_environ): use environ_list_to_c. disable interrupts.
810 (scm_convert_exec_args): take pos and subr arguments and
811 improve error checking.
813 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
815 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
816 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
817 argument to SCM_ASSERT. Furthermore, the name of the function
818 should be passed as first argument when signalling
819 SCM_WNA. (Thanks to Thomas Morgan)
821 * gsubr.c (scm_gsubr_apply): From Radey Shouman
822 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
823 dispatches on the number of actual args has a default case
824 reporting an internal error. This is a vestige from a version
825 that mallocated a SCM vector to hold the arguments. In the
826 current version this check is too late: if it ever happens we will
827 have already overstepped the bounds of the array.
829 Also, the patch [...] adds a check for too many actual arguments."
831 mdj: Removed check for "internal programming error".
833 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
835 * gh_io.c (gh_write): New function.
837 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
838 throw.c (scm_internal_stack_catch): New sibling to the other catch
839 functions. Code moved from gh_eval.c.
840 throw.h: Added header.
841 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
842 scm_internal_stack_catch.
844 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
846 * ioext.h: fix up prototypes.
847 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
848 Scheme name is now dup->fdes.
849 (scm_dup_to_fdes): make the second argument optional and
850 fold in the functionality of scm_primitive_dup.
851 (scm_primitive_dup): deleted.
853 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
855 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
856 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
857 ultrix are defined. Use setvbuf instead of setbuf.
858 (scm_setvbuf): new procedure.
859 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
860 (scm_setfileno): moved from ioext.c.
861 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
862 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
864 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
866 * fluids.c (scm_fluid_p): New function.
867 * fluids.h (scm_fluid_p): New prototype.

871 * print.c (scm_iprin1): Enter printed structures into the print
872 state as nested data while they are printed.
873 (print_state_fluid, print_state_fluid_num): New variables.
874 (scm_init_print): Initialize them.
875 (scm_iprin): If print_state_fluid carries a print_state, use that
876 instead of creating a new one.
877 (scm_printer_apply, apply_stub, struct apply_data): New
878 definitions to help with calling printer functions written in
880 * print.h (scm_printer_apply): New prototype.
882 * struct.c (scm_print_struct): Use scm_printer_apply to call the
883 user defined struct printer.
885 * dynwind.c (scm_dowinds): Handle fluids on the wind list.

889 scm_swap_fluids, scm_swap_fluids_reverse): New functions.
891 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
893 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
894 SCM_ASSERT: arg comes before pos.
896 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
898 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
899 to a list of length zero correctly.
901 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
903 Supply an `fgets' method for port objects to do fast line i/o.
904 * ioext.c (scm_read_line): New function.
905 * genio.c (scm_gen_read_line): New function.

917 * ioext.h: removed scm_duplicate_port prototype.
919 * ioext.c (scm_primitive_dup2): return the new file descriptor
920 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
922 (scm_fdopen): bug fix: don't try to make port unbuffered until its
924 (scm_duplicate_port): deleted, there's now an implementation in
926 (scm_primitive_dup2): do nothing if newfd == oldfd.
928 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
930 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
933 * ioext.h: new prototypes.
934 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
936 * fluids.c (next_fluid_num): don't do
937 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
939 * ports.h: prototypes too.
940 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
942 * fports.h: prototype too.
943 * fports.c (scm_evict_ports): moved from ioext.c.
945 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
947 * ports.c (scm_close_port): return a boolean instead of unspecified.
948 throw an error if an error other than EBADF occurs.
950 * filesys.h: scm_close prototype.
951 * filesys.c (scm_close): new procedure, can close file descriptors
952 and ports (scsh compatible).
954 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
957 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
959 * fluids.c, fluid.h: New files.
960 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
961 (modinclude_HEADERS): Added "fluids.h"

969 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
970 (scm_make_root): Call scm_copy_fluids to make fluid bindings
971 unique for the new root when it has a parent.
973 * smob.h: Include "libguile/print.h" to make scm_print_state
976 * dynl.c (free_dynl_obj): New function to free the dynamic object
977 data. (dynl_smob): Use it.
978 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
979 the dynamic object data below the linking of the object to avoid
980 memory leak when the linking code throws an error. Now the code
981 leaks a whole dynamically linked library when must_malloc throws,
982 but that should be much less likely.
984 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
986 Changes to compile under gnu-win32, from Marcus Daniels:

988 (scm_localtime): Change SCM_EOF to SCM_EOL.
989 (scm_mktime): Likewise.
990 * socket.c: Don't include sys/un.h unless autoconf tells
991 us Unix domain sockets are available.
992 (scm_fill_sockaddr): Ignore Unix domain code.
993 (scm_addr_vector): Likewise.
994 (scm_init_addr_buffer): Likewise.
995 (scm_socketpair): Don't include unless socketpair was
996 found during autoconf.
997 * simpos.c (SYSTNAME): Treat cygwin like Unix.
998 * scmsigs.c (scm_pause): Don't include unless pause was found
1000 * posix.c (scm_getgroups): Don't include unless support function

1002 (scm_setpwent): For setpwent.
1003 (scm_setegid): For setegid.
1004 * net_db.c (scm_inet_netof): Don't include unless support

1006 (scm_lnaof): For inet_lnaof.
1007 (scm_inet_makeaddr): For inet_makeaddr.
1008 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.

1019 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
1020 scm_misc_error, not SCM_EOF.
1022 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
1023 arguments for formatting the error message, not SCM_BOOL_F. I
1024 think this is left over from the (eq? '() #f) days.
1026 * read.c (recsexpr): Give this a dummy definition if
1027 DEBUG_EXTENSIONS isn't #defined.
1029 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

1034 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
1036 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
1039 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
1041 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
1042 alloca.lo will be included in @LIBLOBJS@. Something better than
1043 this should be possible.
1044 * Makefile.in: Regenerated.
1046 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1048 * simpos.h: prototype for scm_primitive_exit.
1049 * simpos.c (scm_primitive_exit): new procedure, terminates the
1050 process without unwinding the stack.
1052 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
1054 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
1055 argument and logior its components together, so the user doesn't
1056 have to do this explicitly. Also, if regexp/basic is supplied, then
1057 turn off REG_EXTENDED.
1058 (scm_init_regex_posix): New regexp/basic symbol.
1059 (REG_BASIC): #define this if it is not already present.
1061 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1063 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
1064 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
1065 (CLEANFILES): New target, clean versiondat.h, libpath.h.
1066 (DISTCLEANFILES): New target, clean *.x.
1067 * Makefile.in: Regenerated.
1069 Tue Jun 24 00:29:07 1997 Jim Blandy <jimb@floss.red-bean.com>
1071 * script.c (scm_compile_shell_switches): Add 1997 to copyright
1072 years in usage message.
1074 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
1075 * Makefile.in: Regenerated.
1077 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
1078 flag; I don't think we support it.
1079 (scm_make_regexp): Make sure the user doesn't pass the
1082 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
1084 (scm_init_regex_posix): Define constants for the REG_mumble flags;
1085 name them according to the SCSH convention: regexp/mumble.
1087 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
1089 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
1091 * Makefile.am (libpath.h): Include the values of all the standard
1092 Makefile directory variables. Print a message, but don't print
1094 (versiondat.h): Print a message, but don't print all the commands.
1095 * load.c: #include "alist.h".
1096 (init_build_info): New function.
1097 (scm_init_load): Call it.
1098 * Makefile.in: Regenerated.
1100 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
1102 * root.c: Establish a reliable catch-all handler for the new root.
1103 After all the Scheme handler function might signal an error too,
1104 and we don't want to lose that.
1105 (cwdr_inner_body): Renamed from cwdr_body.
1106 (cwdr_outer_body): New function, to establish the user's handler,
1107 and pass control to cwdr_inner_body.
1108 (cwdr): Establish the reliable catch-all handler here, and pass
1109 control to cwdr_outer_body.
1110 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
1111 the user's handler through to cwdr_outer_body.
1112 * throw.c (scm_handle_by_message): Move guts into....
1113 (handler_message): New static function.
1114 (scm_handle_by_message_noexit): New function.
1115 * throw.h (scm_handle_by_message_noexit): New prototype.
1117 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
1118 across this. Only works on GCC. Otherwise, we hope for the best.
1119 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
1120 the feeling that real thread systems will not need this...
1122 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
1124 Try to detect when people are using one version of libguile and a
1125 different version of ice-9. People have been skewing things and
1126 sending in bug reports.
1127 * Makefile.am (versiondat.h): New file to generate.
1128 * version.c: #include "versiondat.h", to get version info.
1129 (scm_libguile_config_stamp): New function.
1130 * script.c: #include "version.h".
1131 (scm_compile_switches): Call scm_version to get version number.
1132 * scmconfig.h.in, Makefile.in: Regenerated.
1133 * Makefile.in: Regenerated.
1135 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
1136 primitive definitions under their Scheme names.
1138 * Makefile.am (libguile_la_LDFLAGS): Update library version to
1139 1:2. Helps avoid confusion between installed and uninstalled libs.
1141 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
1144 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
1145 backslash from definition; this should be used like: GDB_INTERFACE;
1147 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1149 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
1150 new port unbuffered until its stream has been set.
1152 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
1154 * ports.h: new prototype.
1155 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
1157 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
1159 Make things compile neatly under Sun's C compiler.
1160 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
1161 * extchrs.c (xmbtowc): Make the second arg a normal char, not
1162 unsigned, because that's what the ANSI function takes.
1163 * extchrs.h (xmbtowc): Corresponding change to prototype.
1164 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
1166 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
1167 argument plain char *.
1168 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
1170 * tag.c (scm_tag): Remove unreachable statement.
1171 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
1172 top of the word, it should be unsigned.
1174 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
1175 is defined, to avoid warnings; it's only used in the
1176 conflict-checking code. Which might go away anyway.
1177 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
1178 conditionals; put the label definition in an #if too, to stifle
1181 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
1182 ChangeLog-threads in the distribution.
1183 * Makefile.in: Regenerated.
1185 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1187 * guile-snarf.in: Changed regexp to support CPPs that insert
1188 whitespace between lexical tokens (which munges the `%%%' snarf
1191 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1193 * load.c (scm_init_load_path): Append $(datadir)/guile to
1194 %load-path, so modules do not have to be installed in Guile's
1195 current version directory.
1197 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
1199 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
1200 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
1201 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
1202 call the sysdep functions with deferred ints.
1203 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
1204 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
1205 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
1208 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
1211 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
1213 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
1215 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
1217 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
1220 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
1222 * eval.c (scm_lookupcar1): New procedure to cope with a race
1223 condition during lookup (when using threads).
1224 (scm_lookupcar): Implement in terms of scm_lookupcar1.
1225 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
1228 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
1230 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
1231 supplied. (Change from Tim Pierce.)
1233 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
1235 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
1236 23:47:01 1997" changelog: Slots are now initialized with `#f' by
1237 default and not `()'. `#f' is the canonical non-value in Scheme,
1240 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1242 * struct.c (struct_printer): New variable that holds a handle on
1243 the Scheme variable *struct-printer*. This variable can be set by
1244 Scheme code to override the printing of structures.
1245 (scm_print_struct): If struct_printer is set, call it. If it is
1246 not set, or returns #f, print the structure in the old fashion.
1247 Include "eval.h" for scm_apply.
1249 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
1251 * struct.c (scm_struct_ref, scm_struct_set_x): Use
1252 scm_struct_i_n_words to get the number of fields, not
1253 -scm_struct_n_extra_words.
1255 On the route to fancier struct printing:
1256 * struct.c (scm_print_struct): New function to print a structure.
1257 Include "genio.h" to support it. This function doesn't do
1258 anything interesting right now, but I think it should be here
1260 * struct.h: Include "print.h" and add prototype for
1262 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
1263 print structures ourself.
1265 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
1267 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
1268 before applying the handler in case it doesn't return.
1270 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
1272 * scmsigs.h, async.h: updated.
1274 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
1277 * posix.c (scm_uname): interpret only negative values as an error.
1278 Solaris normally returns a positive value.
1280 * script.c (scm_compile_shell_switches): if we are not going into
1281 an interactive repl, set scm_mask_ints to zero so that asyncs can
1284 * simpos.c (scm_system): don't ignore/unignore signals around
1287 * posix.c (scm_open_pipe): don't ignore/unignore signals around
1290 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
1291 done in boot-9.scm instead.
1293 * scmsigs.c, async.c: Major rewriting of signal handling code.
1294 (scm_sigaction): new procedure.
1295 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
1297 (scm_raise): return unspecified, throw error on failure.
1299 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1301 * regex-posix.c (scm_init_regex_posix): Register the "regex"
1302 feature, to help boot-9.scm decide whether to import the regex
1305 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1307 * eval.c: Include scmconfig.h at the beginning of the file so that
1308 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
1311 * regex-posix.c: #include "_scm.h" before conditionally #including
1312 <regex.h>; the former defines HAVE_REGCOMP.
1314 * regex-posix.c: #include <regex.h> conditionally, so the file is
1315 CPP'able (for dependency scanning) even on systems that don't have
1318 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
1320 Add new R4RS-compliant syntax for keywords.
1321 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
1322 regardless of the setting of the `keywords' read option.
1323 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
1324 can be re-read no matter what the setting of the `keywords' read
1327 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
1329 Add support for POSIX regular expressions.
1331 * regex-posix.c, regex-posix.h: New files. (Some code
1332 is taken liberally from rx/rgx.c in the old Guile dist.)
1334 * init.c: Include regex-posix.h.
1335 (scm_boot_guile_1): Call scm_init_regex_posix.
1337 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
1338 Add regex-posix.[ch] sources.
1339 * Makefile.in: Regenerated.
1341 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
1342 to do this automatically? It didn't for me, bleh.)
1344 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
1346 * fports.c (print_pipe_port): New function.
1347 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
1348 latter doesn't even take the right arguments.
1350 * Makefile.am: Increment shared lib revision number. I think
1351 sometimes the uninstalled Guile finds the installed shared lib;
1352 Gord says doing this might help. As things turned out, I can't
1353 say whether it does.
1354 * Makefile.in: Regenerated.
1356 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
1357 passing it as the closure argument to scm_boot_guile. (Bill
1360 * ports.c (print_void_port, putc_void_port, puts_void_port,
1361 write_void_port, flush_void_port, getc_void_port, close_void_port,
1362 noop0): Use ANSI prototypes instead of K&R declarations, so the
1363 initialization of void_port_ptob gets aggressively type-checked.
1364 Fix arguments of print_void_port and write_void_port. (Bill

1398 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
1400 * script.c (scm_find_executable): Use prototype-style definition
1401 here; apparently it's not quite right to have const in a prototype
1402 and then use a K&R declaration. I wonder if stuff like this will
1403 go away if we compile with -Wrequire-prototypes, or whatever that
1404 is... (Bernard URBAN)
1406 * scmhob.h: New text from Bernard URBAN.
1408 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1410 * script.c: Don't #define const on hpux. Configure takes care of
1411 this. (Thanks to Larry Schwimmer.)
1413 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
1414 decide whether to #include <unistd.h>, instead of listing a bunch
1415 of systems. Don't #include stdio twice. Removed dyked-out
1416 definition of scm_find_impl_file.
1418 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
1420 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
1421 library version info to 1:0.
1422 * Makefile.in: Regenerated.
1424 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

1428 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
1429 throw.c: Update copyright years; these files have been worked on
1430 significantly in 1997, but only had copyright years for 1996.
1431 Also, change name of copyright holder on some from Mikael
1432 Djurfeldt to Free Software Foundation; he has signed papers
1433 assigning the changes to the FSF.
1435 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
1436 reason not to give the user the option.
1438 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
1439 Return #f on end-of-file when scanning table (i.e. when called
1440 with no arguments). Try to catch errors, when we can.
1441 * posix.c (scm_getgrgid, scm_getpwuid): Same.
1443 * script.h (scm_shell_usage, scm_compile_shell_switches): New
1444 external declarations. These are useful.
1446 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
1448 * posix.c: don't include <sys/select.h> or define macros for
1449 select, since they were not used in this file.
1451 * filesys.c (scm_select): make the fifth parameter microseconds,
1452 not milliseconds. let the fourth parameter be either a real value
1453 or an integer or #f. The first, second and third arguments can
1454 now be vectors: the type of the corresponding return set will be
1456 (set_element, get_element): new static procedures.
1458 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>

1468 (scm_pipob): Use it in the initializer here.
1471 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
1472 Use a meaningful error message when signalling an error. For
1473 this, scm_gethost must check h_errno rather than errno.
1475 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
1477 * Makefile.in: Regenerated, using automake-1.1p.

1489 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
1491 Ensure that shared substrings are handled properly when passed to
1492 a system call or other foreign function. Many thanks to Tim
1494 * symbols.h (SCM_COERCE_SUBSTR): new macro.
1495 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
1496 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
1497 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
1498 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
1499 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
1500 (scm_display_error_message): use RO macros when strings may be RO.
1501 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
1502 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
1503 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
1504 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
1505 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
1506 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
1507 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
1508 scm_strftime), vports.c (scm_make_soft_port): use
1509 SCM_COERCE_SUBSTR to make sure shared substrings are

1514 * error.c (scm_error): Add newline to error message.
1516 * init.c (scm_init_standard_ports): Doc fix.
1518 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1520 * dynl-shl.c: Completely replaced with new code from Bernard
1523 * script.c (scm_ice_9_already_loaded): New variable.
1524 (scm_compile_shell_switches): Use it.
1526 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1528 * filesys.c (scm_input_waiting_p): add missing third argument to
1531 * stime.c (scm_localtime): copy the result of localtime before
1532 calling gmtime in case they share a buffer.
1533 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
1536 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1538 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
1540 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
1542 * Makefile.am (check-local): New target, which causes 'make check'
1543 to run gh_test_c and gh_test_repl, with some trivial input.
1544 * Makefile.in: Rgnrtd.
1546 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
1548 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
1551 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
1553 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
1554 sure how this was supposed to work.
1555 (scm_async_click): don't send SCM_TICK_SIGNAL.
1556 (scm_init_async): don't initialize %tick-thunk.
1558 * the following change doesn't affect the Scheme interface:
1559 gc-thunk is called at the end of garbage collection. however it's
1560 no longer implemented by pretending it's a signal.
1562 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
1563 system async corresponding to scm_gc_thunk.
1564 * async.h: declare scm_gc_async.
1565 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
1566 gc-thunk directly, instead of going through a signal handler.
1567 (scm_gc_async): new variable, points to the GC system-async.
1568 (scm_init_async): save the GC async as scm_gc_async instead
1569 of using system_signal_asyncs.
1570 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
1572 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
1574 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
1575 Don't screw up if we're interrupted.
1576 * Makefile.in: Regeneradet.
1578 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
1580 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
1582 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
1583 we're not using AM_INIT_GUILE_MODULE any more.
1584 * Makefile.in: Reneregated.
1586 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
1588 Functions for finding variable bindings, grace à Tim Pierce.
1589 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
1590 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
1592 Get 'make dist' to work again.
1593 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
1594 * Makefile.in: Regenerated, like a surry without a fringe on top.
1596 Changes for reduced Guile distribution: one configure script,
1598 * configure.in, configure: Removed.
1599 * acconfig.h, acinclude.m4: Moved to parent directory, where the
1600 real configure script lives.
1601 * Makefile.in, scmconfig.h.in: Regenerated.
1603 * init.c: #include "script.h", to get prototype for script.c's
1606 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
1608 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
1609 scm_must_malloc, not raw malloc.
1611 * script.c (scm_compile_shell_switches): Dyke out debugging output
1614 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1616 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
1618 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
1619 system has them. Hope this is safe. Previously
1620 sys/timeb.h was included if HAVE_FTIME was defined or if
1621 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
1622 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
1624 * ioext.c (scm_setfileno): add missing third argument to
1625 scm_misc_error call.
1627 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
1629 * eq.c (scm_equal_p): Correctly compare strings of different
1630 varieties. (Thanks to Tim Pierce.)
1632 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
1634 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
1635 #! block comment must occur on a line all by itself.
1637 Move most of the guts of shell command processing into libguile,
1638 so guile.c can be very small (and eventuallly auto-generated. (I
1639 mean, generated mechanically, not self-generated. Hmm.))
1640 * guile.c, script.c, script.h: New source files.
1641 * init.c (scm_boot_guile_1): Call scm_init_script.
1642 * libguile.h: #include "script.h".
1643 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
1644 targets, for new executable.
1645 (libguile_la_SOURCES): Mention script.c.
1646 (modinclude_HEADERS): Add script.h.
1647 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
1648 not dynamic linking is enabled. This is because we're generating
1649 executables now. Move CY_AC_WITH_THREADS call after those, so the
1650 values of cy_cv_threads_libs captures the libs chosen above.
1651 * Makefile.in, configure, aclocal.m4: Regenerated.
1653 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
1654 We don't maintain this interface any more, and it just confuses
1657 * alloca.c: #include <scmconfig.h>, not <config.h>.
1658 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
1659 it'll get included in disties.
1661 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
1663 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
1664 be distributed, because they confuse people.
1665 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
1667 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
1669 * configure.in: check for presence of gethostent (not present on
1670 OpenBSD by default).
1671 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
1672 * configure, scmconfig.h.in: Regenerated.
1674 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
1676 * backtrace.c (scm_backtrace): Split message string across
1677 newlines properly. GCC is more tolerant of this than other
1680 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
1682 Merge threads directory into libguile.
1683 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
1684 threads.h: New source files.
1685 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
1686 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
1688 (modinclude_HEADERS): Add threads.h, coop-defs.h.
1689 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
1690 coop-threads.c.cygnus, coop-threads.h.cygnus.
1691 * configure.in: If we're using threads, include threads.o in
1693 * _scm.h, libguile.h: threads.h lives in this directory now.
1694 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
1695 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
1696 currently used, but brought along for information's sake.
1697 * ChangeLog-threads: log from old 'threads' directory.
1698 * Makefile.in, configure: Rebuilt.
1700 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
1702 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
1705 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
1707 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
1709 Merge GH interface library into libguile.
1710 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
1711 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
1712 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
1713 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
1715 (EXTRA_libguile_la_SOURCES): ... here.
1716 (pkginclude_HEADERS): Add variable, to get gh.h installed.
1717 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
1718 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
1719 New variables, describing how to build the gh test programs.
1720 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
1721 build the test programs, and we probably should have been linking
1722 libguile.la against them all along, to support AIX shared libs.
1723 Add cflags for threads to CFLAGS; add libs for threads to new
1724 variable THREAD_LIBS, used in Makefile.am.
1725 * ChangeLog-gh: log from old `gh' subdirectory.
1726 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
1728 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
1730 * acconfig.h: Undo change of Apr 9; including the definition of
1731 PACKAGE in the guile headers conflicts with applications' own
1733 * scmconfig.h.in: Regenerated.
1735 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

1742 when PROC is receiving no arguments.
1744 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
1746 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
1747 have S_IFSOCK. This is the case under Ultrix.
1749 * posix.c (scm_status_exit_val, scm_status_exit_val,
1750 scm_status_term_sig, scm_status_stop_sig): Modified to work with
1751 Ultrix versions of WIFSTOPPED, etc., which assume that their
1752 arguments are lvalues (hmm).
1754 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
1756 * eval.c: Doc fixes.
1758 * throw.c: Doc fixes; rearranged.
1760 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
1762 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
1764 * acconfig.h: Added entry for PACKAGE.
1765 * scmconfig.h.in: Regenerated.
1767 Changes to work with automake-1.1n, which has better libtool support.
1768 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
1769 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
1771 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
1773 * Makefile.in: Rebuild.
1775 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1777 * stime.c (scm_mktime): take an optional zone argument.
1778 (scm_localtime): check putenv return value.
1779 (scm_strftime, scm_strptime): moved from posix.c. move #include
1781 stime.h, posix.h: update prototypes.
1782 (bdtime2c, setzone, restorezone): new static procedures.
1783 (scm_mktime, scm_strftime): use them.
1784 (scm_strftime): don't call mktime before strftime. Use
1785 filltime for return value.
1786 (filltime): convert NULL zname to #f.
1787 (scm_strptime): return a count of characters consumed, not
1788 the remaining string.
1790 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1792 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
1793 (scm_mktime): likewise.
1795 Uncomment localtime and mktime.
1797 * configure.in: add AC_STRUCT_TIMEZONE.
1799 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
1801 * stime.c (scm_init_stime): don't define ticks/sec.
1802 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
1803 return value problem and is still portable.)
1805 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1807 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
1808 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
1809 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
1810 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
1811 cpp_err_symbols.c): Corresponding changes.
1812 * Makefile.in: Regenerated.
1814 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1816 * posix.c (scm_putenv): don't check HAVE_PUTENV.
1817 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
1818 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
1819 * putenv.c: new file, from sh-utils 1.12.
1821 * posix.c (scm_environ): use malloc in place of scm_must_malloc
1822 since allocation isn't for Scheme objects.
1823 (scm_putenv): copy strings before placing in the environment.
1825 * stime.c (scm_current_time): throw an error if time returns -1,
1826 instead of returning #f.
1827 (scm_get_internal_real_time, scm_get_internal_real_time): use
1828 scm_long2num for return value instead of SCM_MAKINUM.
1830 * stime.h: prototypes updated.
1832 * stime.c (scm_time_in_msec): apparently unused, deleted.
1834 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
1836 * configure.in: check for gettimeofday.
1838 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
1839 which may be more usefully portable than a gettimeofday interface.
1841 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
1843 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
1845 * Makefile.in: Regenerated.
1847 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1849 * stime.c (filltime): recovered static procedure.
1850 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
1853 * posix.h: add prototype for scm_close_pipe, remove prototypes for
1854 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
1856 * posix.c (scm_mknod): split the mode argument into type and perms
1857 arguments, like the extra fields returned by stat.
1859 * fports.c (scm_pipob): set the close, free and print procedures.
1860 (scm_close_pipe): new procedure.
1862 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
1863 define them in boot-9.scm
1865 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1867 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
1868 wan't defined. Don't include fd.h.
1870 * Previously fd.h was regenerated whenever configure was run,
1871 forcing a couple of files to be recompiled.
1873 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
1874 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
1875 Check for _fileno as well as _file.
1877 * ioext.c: don't fd.h.
1878 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
1881 * Change the stratigy for getting information about errno
1882 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
1883 generating lists of symbols during the build process, which will
1884 not always work, include comprehensive lists in the distribution.
1885 To help keep the lists up to date, the "check_signals" and
1886 "check_errnos" make targets can be used.
1888 * configure.in: don't check for a command to extract errno codes.
1889 * Makefile.am: update file lists, remove errnos.list and errnos.c
1890 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
1891 check_errnos targets.
1892 (CLEANFILES): remove errnos.c and errnos.list, add
1893 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
1894 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
1895 * errnos.default: deleted.
1896 * cpp_signal.c: new file.
1897 * cpp_errno.c: renamed from errnos_get.c.
1898 * cpp_err_symbols, cpp_sig_symbols: new files.
1899 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
1900 * error.c (scm_init_error): #include cpp_err_symbols instead of
1902 * posix.c (scm_init_posix): don't intern signal symbols. #include
1905 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
1907 * strop.c (scm_i_index): allow the lower bound to be equal to the
1908 length of the string, so a null string doesn't always give an error.
1910 * posix.h: new prototypes.
1911 * posix.c (scm_status_exit_val, scm_status_term_sig,
1912 scm_status_stop_sig): new functions, as in scsh. They break down
1913 process status values as returned by waitpid.
1915 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
1917 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
1918 configure doesn't know about it.
1920 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1922 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
1924 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
1925 which defines C variables with global linkage.
1927 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1929 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
1932 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
1934 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
1935 has time to check why this doesn't work well with continuations.
1937 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
1939 * Fix shell syntax error; some shells won't tolerate
1940 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
1942 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
1944 * posix.c (scm_uname): throw an error if uname fails instead
1947 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
1949 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
1952 * async.c (scm_ints_disabled): definition moved from error.c.
1954 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1956 * acconfig.h: Removed PACKAGE.
1958 * scmconfig.h.in: Regenerated.
1960 * snarf.h: g++ says it's non-portable not to specify the first
1961 argument in a varargs declaration. I introduced the first
1962 argument by using preprocessor conditionals.
1964 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
1966 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
1967 (scm_freopen): use RO string macros for filename and modes.
1968 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
1970 * posix.c (scm_getgrgid): simplify conversion of name to C string.
1971 (scm_mknod): use RO string macros for path.
1973 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
1974 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
1976 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
1977 use SCM_ROSTRINGP and SCM_ROCHARS.
1979 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1981 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
1984 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
1985 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
1986 support for byte vectors.
1988 * print.c (scm_iprin1): Limit number of vector elements printed
1989 according to pstate->length.
1991 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1993 * backtrace.c (scm_display_error_message): don't segv if message
1996 * error.h: prototype for scm_error_scm.
1998 * error.c (scm_error_scm): new procedure, reimplements scm-error
1999 in C and uses scm_error.
2001 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2003 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2004 pointer to the Scheme variable read-hash-procedures and intern it
2005 in scm_init_read. Modify scm_read_hash_extend and
2006 scm_get_hash_procedure to use the pointer.
2008 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2010 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2011 (SCM_KEYWORD_STYLE): defined.
2013 * read.c (scm_read_opts): add a keywords option. This isn't a
2014 boolean option, in case someone wants to add support for DSSSL
2016 Setup scm_keyword_prefix symbol.
2017 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2019 I've left keyword support disabled by default, since it doesn't
2020 seem to break the module system and it gives R4RS standard behaviour.
2021 It can be reactivated with (read-set! keywords 'prefix).
2023 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2025 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2026 before constructing arbiter.
2028 * eval.c (scm_m_define): Bugfix: Check that the object is a
2029 closure before setting the procedure property!
2031 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2033 * ports.c: Removed `ungetc-char-ready?'.
2035 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2037 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2038 (idea from Mikael: make it a pair so scm_permanent object only
2040 (scm_read_hash_extend): don't call scm_permanent_object.
2041 (ideas from Mikael): if chr is already in the list, replace its
2042 procedure instead of appending it again. If proc is #f, remove
2044 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2046 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
2048 * gdbint.c (gdb_read): update scm_lreadr usage.
2050 * load.h: update prototypes.
2052 * load.c (scm_primitive_load, scm_read_and_eval_x,
2053 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
2055 * read.h: add prototype for scm_read_hash_extend. Change args for
2058 * read.c (scm_read_hash_procedures): new variable.
2059 (scm_read_hash_extend): new procedure.
2060 (scm_get_hash_procedure): new procedure.
2061 (scm_lreadr): use scm_get_hash_procedure instead of an argument
2062 for extended # processing.
2063 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
2064 scm_read_token): remove case_i, sharp arguments. Change callers.
2066 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
2068 * read.h (SCM_N_READ_OPTIONS): increase to 3.
2069 (SCM_CASE_INSENSITIVE_P): define.
2071 * read.c: add case-insensitive option to scm_read_opts.
2072 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
2073 to determine whether to convert symbol case.
2074 (default_case_i): definition removed.
2075 * read.c (scm_read_token): if case_i, downcase ic before doing
2078 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2080 * configure.in: Added configuration option `guile-debug'.
2081 Configure with --enable-guile-debug if you want a bunch of extra
2082 functions used for debugging when developing Guile.
2084 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
2086 * procs.c (make-cclo): New undocumented debugging procedure: Make
2087 compiled closure with internal procedure PROC and length LENGTH.
2088 Only compiled if GUILE_DEBUG is defined.
2090 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
2092 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
2094 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
2096 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
2097 with 3 or more args internally to the evaluator.
2099 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2101 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
2102 with 3 or more args internally to the evaluator. This is mainly
2103 because we don't want to pass entry and exit points of the
2104 debug support twice, but it also seems to increase the speed of
2105 the evaluator for such calls (e. g. (+ 1 2 3)).
2107 * backtrace.c (scm_display_application): New procedure:
2108 display-application; Set fancy printing parameters individually
2109 for different types of display (backtrace, error, application).
2110 (These should of course be customizable!)
2112 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
2113 clear the CHECK-flags.
2115 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2117 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
2119 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2121 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
2122 from pairs with a GLOC in the car.
2124 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
2125 otherwise `symbol-hash' will behave badly.
2126 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
2127 we get segmentation fault!
2129 * symbols.c: Added #include "weaks.h". New functions:
2130 `builtin-bindings' and `builtin-weak-bindings'. (These will be
2131 moved to an extraneous library when we split libguile.)
2133 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2135 * filesys.c (scm_stat): stat now takes fport arguments too as
2136 documented in the manual.
2138 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2140 * debug.c (scm_single_step): Bugfix: Call continuation with
2141 scm_call_continuation instead of throwing to it.
2143 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2145 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
2146 argument wasn't declared to be optional.
2148 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2150 * stime.c (scm_init_stime): Add feature "current-time".
2152 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2154 * throw.h: prototype for scm_exit_status.
2155 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
2156 args to derive an exit status. Allows (quit) to work from a
2158 (scm_exit_status): new function.
2161 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2163 * eval.c (scm_deval): Removed some old code.
2164 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
2166 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
2169 * symbols.c (msymbolize): Bugfix: Must initialize property list to
2172 * procs.c: Introduce the existent C function scm_thunk_p at the
2173 Scheme level as well.
2175 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2177 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
2178 used from C to easily lookup the value of a symbol in the current
2181 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2183 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
2184 scm_init_unif in this file. This will also fix a previous problem
2187 * configure.in: Added AM_MAINTAINER_MODE
2189 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2191 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
2194 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2196 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
2197 source files that are not always included in libguile but should
2198 have their dependencies calculated by automake. This variable is
2199 recognized by automake, no further magic is needed.
2200 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
2201 to deal exclusively with *.lo files, as it seems. The *.o files
2202 are built automatically when the corresponding *.lo file gets
2205 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
2207 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
2210 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
2212 * unif.c (scm_array_set_x): minor change to argument error checking.
2214 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
2216 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
2217 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
2218 They should only be included in the library at configure.in's
2220 (libguile_la_LDADD): Include the appropriate .lo files here.
2221 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
2222 so we know when to build them (and their .lo bretheren).
2223 * configure.in (LIBLOBJS): New substituted variable. We let
2224 configure decide which .o files to include in LIBOBJS, and then
2225 put the corresponding list of .lo files in LIBLOBJS. The latter
2226 is what we pass to libtool.
2227 * Makefile.in, configure: regenerated.
2229 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
2231 * symbols.c (scm_sysintern0): New function. Contains the core of
2232 old scm_sysintern but doesn't take a second value argument.
2233 (scm_sysintern): Now uses scm_sysintern0.
2234 (scm_sysintern_no_module_lookup): Renamed to
2235 scm_sysintern0_no_module_lookup and doesn't take a second value
2236 argument any longer.
2238 * symbols.h (scm_sysintern0: Added declaration.
2240 * options.c (scm_init_opts): Use scm_sysintern0 instead of
2241 scm_sysintern when interning option keys. Otherwise we risk
2242 destroying the values of already interned variables.
2244 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
2245 scheme-level boolean (use SCM_NFALSEP).
2247 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
2249 (scm_backtrace): New function. (C version of old function from
2250 boot-9.scm) Motivation: Make it possible to display backtraces
2251 without depending on boot-9.scm. (I'm uncertain if this
2252 motivation is good enough...)
2254 * root.h (scm_root_state): Add member the_last_stack_var.
2255 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
2257 * root.c (mark_root): Mark scm_the_last_stack_var.
2259 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
2262 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
2264 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
2265 1. mark_lazy_catch didn't mark the smob.
2266 2. Both functions above have standard variants:
2267 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
2268 free_lazy_catch --> scm_free0.
2270 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
2272 * throw.c (scm_internal_lazy_catch): New function.
2273 (scm_lazy_catch): Rewritten to use it.
2274 (scm_ithrow): Handle the new lazy catch representation.
2275 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
2276 that doesn't have a jmpbuf is a lazy catch clause.
2277 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
2278 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
2279 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
2281 (scm_init_throw): Register the new lazy-catch smob type.
2282 * throw.h (scm_internal_lazy_catch): decl for new function.
2284 * throw.c (scm_internal_catch): Doc fixes.
2286 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
2287 configure.in. Including this might cause problems if applications
2288 that link against libguile include their own copies of alloca, but
2289 if they're using autoconf, they should be adding libguile to LIBS
2290 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
2291 the copy in libguile, and things will be okay. (I think.)
2293 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2295 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
2297 strop.h: move prototypes too.
2299 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2301 * posix.c (scm_init_posix): don't intern EINTR since it's now done
2304 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
2305 etc. I deleted them from filesys.c long ago, but didn't
2306 notice they were here too (although ineffective since
2307 sys/stat.h wasn't included).
2309 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
2311 * eval.c: Don't define alloca in GCC case. gcc will automatically
2312 use __builtin_alloca if appropriate.
2314 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2316 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
2317 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
2318 that values of automatic variables are preserved. See comments
2319 for safe_setjmp for details.
2321 Change from Thomas Morgan:
2322 * variable.c: Include eq.h.
2323 (var_equal): New function.
2324 (variable_smob): Use var_equal as the discriminator for variables.
2326 * throw.c (s_throw): Remove extraneous declaration.
2328 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
2329 * eval.c: Add necessary CPP cruft to support that.
2330 * configure, Makefile.in, scmconfig.h.in: regenerated.
2332 Change from Thomas Morgan:
2333 * procprop.c (scm_procedure_properties): Convert the Scheme
2334 boolean returned by scm_procedure_p into a C boolean before using
2335 it as a condition for SCM_ASSERT.
2336 (scm_procedure_property): Likewise.
2338 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
2339 indications of Unixness.
2342 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2344 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
2346 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2348 * read.c (scm_lreadr): use scm_misc_error to improve one of the
2349 "unknown # object" error messages.
2351 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
2352 (scm_i_index) and declare it static. Add a 'direction' argument
2353 to indicate what way the search should go.
2354 (scm_i_index): throw out-of-range error instead of wrong-type-arg
2356 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
2357 strop.h: remove scm_i_index, scm_i_rindex prototypes.
2359 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2361 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
2363 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
2364 to avoid clash with various scsh forks.
2366 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
2368 The following two changes (ramap.c, throw.c) are motivated by the
2369 apparent unportability of forward declarations of static arrays of
2370 the form `static foo bar[];'.
2372 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
2373 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
2375 * throw.c (scm_throw): Moved above scm_ithrow.
2377 * options.h: Removed the extern declarations of scm_yes_sym and
2378 scm_no_sym since these are static.
2380 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2382 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
2384 * Makefile.am: remove AWK=@AWK@.
2385 Add a rule for generating errnos.list.
2386 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
2388 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
2389 don't extract errnos, just set a variable (avoids the
2390 need to recompile error.c just because configure is run.)
2392 * unif.h: update prototypes.
2393 * unif.c (scm_uniform_array_read,write): change the offset and
2394 length arguments to start and end, for consistency.
2396 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
2398 * ioext.h: update prototypes.
2399 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
2400 scm_read_line_x, it's a more general procedure using an
2401 interface from scsh. read-line and read-line! are now defined
2403 Note that the new read-line trims the terminator
2404 by default, previously it was appended to the returned string. An
2405 optional argument specifies how to process the terminator (scsh
2406 compatible). For the old behaviour: (read-line port 'concat).
2407 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
2408 returns a pair, but is converted to multiple values if the scsh
2411 socket.h: update prototypes.
2412 * socket.c (scm_recvfrom): for consistency with other procedures,
2413 take start and end as separate optional arguments.
2414 (scm_recv, scm_recvfrom): don't allow the second argument
2415 to be a size, only a buffer. Change the scheme names to
2416 recv! and recvfrom!. Don't return the buffer.
2418 * ioext.h, posix.h: move prototypes too.
2419 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
2420 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
2421 "read.h" and "unif.h".
2422 * ioext.c: include "chars.h"
2424 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
2426 * dynl.c: The dynamic linking and module registration functions
2427 are now defined even when dynamic linking is not available for the
2428 host system. Some of their functionality can be done without
2429 dynamic linking; when it's really needed, they throw errors.
2431 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
2433 * configure.in: Only define DYNAMIC_LINKING when one of the system
2434 dependent functions is detected.
2435 * dynl.c (scm_dynamic_func): New function to get the address of a
2436 function in a dynamic object.
2437 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
2438 produced by scm_dynamic_func as the thing to call.
2440 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
2442 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
2443 (scm_register_module_xxx, scm_registered_modules,
2444 scm_clear_registered_modules): New functions.
2446 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
2448 * symbols.c (scm_sysintern): Renamed to
2449 scm_sysintern_no_module_lookup.
2450 (scm_sysintern): New function to take the place of the old
2451 scm_sysintern. It uses the current toplevel lookup closure to give
2452 the symbol its value. This is a temporary hack to put packages
2453 like gtcltk into their own module.
2454 (scm_can_use_top_level_lookup_closure_var): New variable to tell
2455 us whether `scm_top_level_lookup_closure_var' has been initialized
2457 * eval.c (scm_init_eval): Set it.
2459 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2461 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
2462 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
2464 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
2466 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
2467 scm_sys_dup): deleted: FD capability will be added to other
2469 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
2470 scm_fd_free, fd_smob, scm_intern_fd.
2471 (scm_open): renamed from scm_sys_open. Return a port instead of
2472 an FD object. Make the mode argument optional.
2473 (scm_sys_create): deleted, it's just a special case of open.
2474 (scm_init_filesys): move interning of constants O_CREAT etc.,
2475 here (were previously using SCM_CONST_LONG macro).
2476 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
2478 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
2479 include "fports.h" and <stdio.h>
2480 (scm_stat, scm_select): don't support FD objects.
2482 * error.h: adjust scm_syserror_msg prototype.
2483 * error.c (scm_syserror_msg): take an extra argument for errno.
2484 Using the global value didn't always work, since it could be
2485 reset by procedure calls in the message or args arguments.
2487 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
2488 I don't understand why the check was there (and what about the
2491 * strop.c (scm_string_copy): allow shared substrings to be copied.
2493 * unif.h: corresponding change to prototypes.
2494 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
2495 recognize two new optional arguments: offset and length. Allow
2496 the port argument to be an integer (file descriptor, for scsh).
2497 Include <unistd.h> for "read" prototype.
2499 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2501 * socket.c: don't include filesys.h.
2503 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
2505 * Makefile.am: add AWK=@AWK@ (?)
2507 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
2509 Add a rule to generate errnos.c from errnos.
2510 * error.c (scm_init_error): include errnos.c.
2511 * errnos_cnvt.awk: new file, converts the list of errno codes to
2513 * errnos_get.c: new file.
2514 * errnos.default: new file, contains errnos to try if they can't
2515 be extracted from errno.h.
2516 * configure.in: if using GCC, try and extract errno codes from
2520 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
2522 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
2523 * Makefile.am: Made libguile into a libtool library.
2524 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
2525 Set libtool_libs to indicate that libguile is a libtool library.
2526 See guile/ChangeLog for details.
2527 * .cvsignore: ignore "*.lo", the libtool library objects.
2529 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2531 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
2532 use htons in getservbyport argument.
2534 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2536 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
2537 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
2540 * objprop.c (scm_object_property): No need to take the CDR of the
2541 value returned by scm_object_properties, since Aug 20 change.
2543 * configure.in: When checking for struct linger, #include
2544 <sys/types.h> as well as <sys/socket.h>. I've never known
2545 <sys/types.h> to cause any portability problems, and Solaris's
2546 <sys/socket.h> needs it.
2547 * configure: Rebuilt.
2549 I think the Sun compiler has chosen a perverse way to interpret
2550 ANSI declarations combined with K&R definitions. We'll
2551 appease it a little bit. But when it invades France, we fight.
2552 * print.c (scm_iprlist): Change 'tlr' argument to an int.
2553 * print.h (scm_iprlist): Here too.
2554 * numbers.c (scm_divbigdig): Change definition to match
2555 declaration in numbers.h.
2556 * unif.c (scm_makflo): Change definition to match declaration in
2559 * init.c (scm_boot_guile): Don't return the value of
2560 scm_boot_guile_1. This function doesn't return a value;
2561 scm_boot_guile_1 doesn't return a value (or return at all).
2563 * eval.c (unmemocopy): Add a semicolon to appease the Sun
2566 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
2567 compile. I have a feeling this function is a bad idea anyway ---
2568 one should always test for features, not systems.
2570 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
2571 semicolons. Only pure luck kept this from being noticed earlier.
2573 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
2575 * socket.c (scm_recvfrom): Added missing semicolon.
2577 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2579 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
2580 the buffer and start and end positions for scsh networking
2583 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
2585 * configure.in: Revert previous change to this file; the problem
2586 is due to transient automake weirdness.
2587 * configure: Rebuilt.
2589 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
2590 PLUGIN/guile.libs. configure generates the latter from the former.
2591 * Makefile.in: Rebuilt.
2593 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
2594 need this if we install scripts, like guile-snarf.
2595 * configure: Rebuilt.
2597 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2599 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
2601 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
2603 * socket.c (scm_addr_vector): fix faulty scm_listify.
2605 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
2607 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
2608 style block comment is no longer considered an error.
2610 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
2612 * PLUGIN/guile.libs.in: New file.
2613 * PLUGIN/guile.libs: Removed from repository.
2614 * configure.in: Create PLUGIN/guile.libs from
2615 PLUGIN/guile.libs.in. This is for including additonal libraries
2616 needed for dynamic linking.
2617 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
2618 instead of PLUGIN/guile.libs.
2620 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
2622 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
2624 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
2625 occurrences of the given element from the list, not just the
2626 first. This is how the Emacs Lisp functions behave, how the
2627 analogous Common Lisp functions behave, and (I believe) how the
2628 older Maclisp functions worked. I realize that this change may
2629 break code, but it seemed better to break it before the Guile
2632 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
2633 Their prototypes were already present in gc.h, but they weren't
2635 (scm_init_storage): Initialize scm_protects.
2636 * root.c (scm_protects): New element of scm_sys_protects.
2638 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
2640 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
2642 * libguile.h: Added #include "libguile/net_db.h".
2644 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
2645 30 change. That file is only meant for communication between the
2646 configuration process and load.c. If code linked against libguile
2647 wants to get at the paths mentioned in libpath.h, it can call
2648 functions declared in load.h.
2650 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2652 * libguile.h: Removed #include "libguile/fdsocket.h"
2654 * net_db.c: Added #include <sys/socket.h>.
2656 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
2658 * filesys.c (scm_input_waiting_p): use select in preference to
2659 FIONREAD, since the latter doesn't detect EOF.
2660 Throw error if neither select nor FIONREAD available.
2662 * socket.c (scm_connect): take a port, not a fd object.
2663 (scm_fill_sockaddr): throw an error if fam is not recognised.
2664 (scm_bind): use scm_fill_sockaddr.
2665 (scm_listen): take a port, not a fd object.
2666 (scm_accept): take and return a port. return #f in the car if
2667 address can't be got
2668 (scm_sock_fd_to_port): new procedure.
2669 (scm_socket): use scm_sock_fd_to_port.
2670 (scm_addr_vector): throw error if unrecognised address type.
2671 take an extra argument with the calling procedure name.
2672 (scm_getsockname): take a port. return #f if address can't be got.
2673 (scm_getpeername): take a port. return #f if address can't be got.
2674 (scm_recvfrom): take a port. return #f for address component if can't
2676 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
2677 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
2679 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
2681 * throw.c (scm_internal_catch): Make body funcs and handler funcs
2682 use separate data pointers, to allow them to be designed
2683 independently and reused.
2684 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
2685 Renamed from catch_body, catch_handler, and uncaught_throw; made
2687 (struct scm_catch_body_data): Renamed from catch_body_data; moved
2689 (scm_catch): Use the above.
2690 (scm_throw): Don't bother printing a message for an uncaught
2691 throw; we establish a default handler in init.
2692 * throw.h (scm_internal_catch): Prototype updated.
2693 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
2695 (struct scm_body_thunk_data): New structure, used as data
2696 argument to scm_body_thunk.
2697 * init.c (struct main_func_closure): New structure, packaging up
2698 the data to pass to the user's main function.
2699 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
2700 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
2701 scm_internal_catch to establish a catch-all handler, using
2702 scm_handle_by_message. This replaces the special-case code in
2704 (invoke_main_func): Body function for scm_internal_catch; invoke
2705 the user's main function, using the main_func_closure pointer to
2706 decide what to pass it.
2707 * root.c (struct cwdr_body_data): Remove handler_proc member.
2708 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
2709 (cwdr_handler): Removed.
2711 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
2713 * socket.h (SCM_P): update bind prototype.
2714 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
2715 include "feature.h".
2716 (scm_socket): return a port, not a file descriptor object.
2717 include "fports.h" and <unistd.h>
2718 (scm_bind): take a port, not a file descriptor object.
2719 take an extra argument for address args.
2721 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
2722 INADDR_NONE, INADDR_LOOPBACK.
2724 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
2726 * init.c: include net_db.h and not fdsocket.h.
2727 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
2729 * Makefile.am: corresponding changes.
2730 * socket.h: renamed from fdsocket.h, fix names.
2731 * net_db.h: renamed from socket.h, fix names.
2732 * socket.c: renamed from fdsocket.c.
2733 remove _sys from procedure names.
2734 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
2735 add "socket" to features list.
2736 * net_db.c: renamed from socket.c.
2737 remove _sys from procedure names.
2738 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
2739 add "net-db" to features list.
2740 include "net_db.h". don't include <sys/socket.h> or
2743 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2745 * tags.h (scm_tags): Removed comma at end of last enumerator.
2747 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
2749 Don't use GCC extensions to allocate space for debugging frames.
2750 (Here he goes again! Why do we put up with this?!)
2751 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
2752 an scm_debug_info structure, not an in-line array of them. Add
2753 'info' member, to say how many vect elements we've used, for eval
2755 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
2756 a new variable debug_info_end to mark the end of vect, instead of
2757 the address of the 'info' pointer itself.
2758 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
2759 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
2760 (SCM_APPLY): Explicitly allocate space for debug.vect.
2761 * debug.c (scm_m_start_stack): Same, for vframe.vect.
2762 * stacks.c: Adjusted for new debug frame structure.
2763 (RELOC_INFO, RELOC_FRAME): New macros.
2764 (stack_depth, read_frames): Use them, and new scm_debug_frame
2765 element 'info', instead of magically knowing that eval frames have
2766 an info pointer sitting after vect.
2767 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
2769 (scm_init_stacks): Formatting tweaks.
2771 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
2773 Give GCC more control flow information, so it can be sure that
2774 variables aren't used uninitialized.
2775 * error.h (scm_error, scm_syserror, scm_syserror_msg,
2776 scm_sysmissing, scm_num_overflow, scm_out_of_range,
2777 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
2778 scm_misc_error): Tell GCC that these functions never return.
2779 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
2780 out the field type, call abort if SCM_ASSERT returns, to placate
2782 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
2783 scm_wta ever returns. We can't handle this case anyway, and this
2784 gives the optimizer more information.
2785 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
2786 scm_wta ever returns.
2788 In some cases, the code is fine, but GCC isn't smart enough to
2789 figure that out; this usually happens when one variable is only
2790 initialized and used when a particular condition holds true, and
2791 we know that condition will never change within a given invocation
2792 of the function. In this case, we simply initialize the variables
2793 to placate the compiler, hopefully to a value which will cause a
2794 crash if it is ever actually used.
2795 * print.c (scm_iprin1): Initialize mw_pos.
2796 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
2797 * throw.c (scm_ithrow): Initialize dynpair.
2798 * unif.c (scm_uniform_vector_ref): Initialize cra.
2799 * struct.c (init_struct): Initialize prot.
2800 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
2802 * strports.c (scm_eval_0str): Don't return uninitialized garbage
2803 if EXPR contains no expressions.
2805 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2807 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
2808 cause an infinite loop (???). So much for the algebraic
2809 equivalency of variable-sized arrays and alloca...
2811 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
2813 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
2814 a SCM boolean, not a C boolean.
2816 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
2818 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
2819 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
2820 rules for raising scm_mtrigger. Previously, unfortunate but not
2821 unlikely circumstances could result in almost constant invokation
2822 of the gc. Now, this situations should be less likely, but they
2823 are not prevented completely.
2825 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
2827 * numbers.c (scm_fuck): Procedure removed; looks like old test
2829 * numbers.h: Prototype removed.
2831 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
2833 * debug.h (scm_debug_frame): Change `vect' member from an in-line
2834 array to a pointer, to match my Nov 21 change in eval.c.
2836 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2838 * libguile.h: Added #include "libguile/backtrace.h", #include
2839 "libguile/stacks.h".
2841 * strings.c (scm_string scm_make_string scm_string_ref
2842 scm_string_set_x scm_string_equal_p scm_string_append):
2843 Bugfix according to scm patch from Aubrey Jaffer:
2844 Corrected long-standing
2845 (not (eqv? (integer->char 128)
2846 (string-ref (make-string 1 (integer->char 128)) 0)))
2847 bug found by John Kozak <jk@noontide.demon.co.uk>.
2849 * strports.c, strports.h: Make scm_eval_0str return the value of
2850 the last expression evaluated (previously, it returned void).
2852 * strports.c, strports.h: New function: scm_read_0str. Does what
2855 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2857 * simpos.c (scm_getenv): return #f if string can't be found in the
2858 environment instead of throwing an exception, for compatibility
2859 with numerous other systems.
2861 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
2863 * Makefile.am (.c.x): Use guile-snarf.
2864 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
2866 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
2868 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
2870 * backtrace.c (scm_display_error_message): Made non-static, and
2871 renamed from display_error_message.
2872 * backtrace.h (scm_display_error_message): Added extern decl.
2873 * throw.c (uncaught_throw): Use it to display the error message.
2875 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
2877 * inet_aton.c: Use #if 0, not #ifdef 0.
2879 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
2881 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
2882 to convert the returned value.
2883 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
2884 the offset argument.
2886 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
2888 Add new interface to catch/throw, usable from C as well as
2890 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
2891 (scm_internal_catch): New function, replaces...
2892 (scm_catch_apply): Deleted.
2893 * throw.c (scm_catch_apply): Deleted; replaced with a more general
2894 mechanism which is a bit more code, but can be used nicely from C
2895 and implement the Scheme semantics as well.
2896 (scm_internal_catch): This is the replacement; it's named after
2897 the analogous function in Emacs.
2898 (scm_catch): Reimplemented in terms of the above.
2899 (struct catch_body_data, catch_body, catch_handler): New
2900 functions, used by scm_catch.
2901 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
2902 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
2903 support for new cwdr.
2905 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
2908 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
2910 * acconfig.h: Added DYNAMIC_LINKING symbol.
2911 * configure.in: Add option and checks for dynamic linking.
2912 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
2913 dynl.h: New files for dynamic linking support.
2914 * Makefile.am (libguile_a_SOURCES):
2916 (modinclude_HEADERS): Added "dynl.h".
2917 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
2919 * init.c (scm_boot_guile_1): Call
2920 scm_init_dynamic_linking to initialize dynamic linking support.
2922 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
2924 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
2925 (as we Schemers say). It needs to be global, so that I can tweak
2926 it for the proper operation of unexec.
2927 (scm_boot_guile_1_live): New variable, see above.
2929 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
2931 * guile-snarf.sh: Removed.
2932 * PLUGIN/guile.libs: Added dependency for -lm.
2933 * acinclude.m4: Renamed from aclocal.m4.
2934 * PLUGIN/greet: Removed.
2935 * Makefile.am, aclocal.m4: New files.
2936 * configure.in: Updated for Automake.
2938 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
2940 * eval.c (scm_definedp): Use top_level_lookup_closure_var
2941 and not top_level_lookup_thunk_var.
2943 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
2945 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
2947 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
2949 * eval.c (scm_definedp): Incompatibly changed to be a builtin
2950 Scheme function, instead of syntax. Single argument is now a
2953 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2955 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
2956 scm_ra_divide): Properly terminate statements passed as arguments
2957 to IVDEP macros. (Thanks to Bernard Urban.)
2959 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
2960 with non-constant sizes. (Thanks to Bernard Urban.)
2962 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
2964 It's an "eval closure", not an "eval thunk." A thunk is a
2965 function of no arguments.
2966 * root.h (struct scm_root_state): Renamed
2967 top_level_lookup_closure_var from top_level_lookup_thunk_var.
2968 (scm_top_level_lookup_closure_var): Renamed from
2969 scm_top_level_lookup_thunk_var.
2970 * root.c (mark_root): Uses changed.
2971 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
2972 * init.c (scm_start_stack): Uses changed.
2973 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
2974 Change scheme-visible name to *top-level-lookup-closure* from
2975 *top-level-lookup-thunk*.
2977 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
2979 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
2980 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
2982 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
2984 * gc.c (struct scm_heap_seg_data): Doc fixes.
2986 * gc.c (scm_gc_sweep): Empty all segments' freelists before
2987 sweeping. Then, prepend each segment's free cells to its
2988 freelist, rather than wiping out the old value. (Thanks to Marius
2991 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
2992 scm_check_freelist, scm_debug_newcell): New functions and
2993 variables, for debugging freelist problems.
2994 * pairs.h (SCM_NEWCELL): New debugging version added.
2995 * gc.h (scm_debug_newcell): Added extern declaration, used by
2996 debugging version of SCM_NEWCELL.
2998 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3000 On some systems <libc.h> conflicts with <unistd.h>, and should not
3001 be #included at all.
3002 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3003 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3004 * configure.in: Call it.
3005 * posix.c, filesys.c: Use its results to decide whether or not to
3007 * configure, scmconfig.h.in: Rebuilt with autoconf and
3010 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3012 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3013 pointer to the stdio stream before calling scm_setbuf0, so the
3014 latter will be able to retrieve it. I'm surprised this didn't
3015 segfault earlier. (Thanks to Christopher Lee.)
3017 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3019 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3022 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3024 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3025 number of stack narrowing specifier pairs. The first specifier in
3026 a pair controls inner border, the second the outer border. A
3027 number means cut that number of frames, a procedure object means
3028 cut until that object is found in operator position in a frame.
3030 * root.c (cwdr): Bugfix.
3032 * read.c: Recording of positions disabled by default.
3034 * procs.c (scm_closure_p): New function.
3036 * posix.c (scm_tmpnam): New function.
3038 * load.c: Added #include "throw.h".
3039 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3042 * load.c, load.h (scm_read_and_eval_x): New function.
3044 * eval.c: Renamed debug option "deval" to "debug".
3046 (scm_eval_x): `eval!' is no longer accessible from the scheme
3047 level. Motivation: We can't allow operations which introduce
3048 glocs into the scheme level. Guile's type system can't handle
3049 these as data. Use `eval' or `read-and-eval!' as replacement.
3051 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
3052 SCM_CONSP since this is a macro!; Set vframe.prev to
3053 scm_last_debug_frame instead of 0. In this way we can look
3054 "above" the virtual start stack frame if we wish.
3055 (scm_debug_hang): New function: Useful for debugging Guile in
3056 certain tricky situations. Will probably be removed later...
3058 * debug.h: Changed semantics of debug option "backtrace". This
3059 option now only indicates whether we want automatic backtrace at
3062 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3064 * ports.c: #include "filesys.h"
3065 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
3067 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
3068 Motivation: This is system specific code which is related to file
3069 I/O. It also may use select. Added code by Gary Houston to
3070 detect presence of character in stdio buffers.
3072 * libguile.h: #include "libguile/libpath.h"
3074 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
3075 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
3076 SCM_SITE_DIR; Install libpath.h among the other include files.
3078 * load.c, load.h (scm_sys_package_data_dir): New function.
3080 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3082 * stacks.h: Bugfix: Don't use tail-array length field as stack
3083 length field! This screwed GC.
3085 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3087 * _scm.h: Added #ifndef around definition of macros min and max.
3089 * __scm.h: Added hooks for threads to plugin to in ints protection
3090 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
3091 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
3092 the main code in these macros duplicated and spread over multiple
3093 files. Renamed SCM_THREADS_SWITCHING_CODE ->
3094 SCM_THREAD_SWITCHING_CODE.
3096 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
3098 * snarf.h: New file.
3099 * guile-snarf.sh: New file.
3100 * Makefile.in (inner_h_files): Added snarf.h
3101 (ancillary, install, uninstall, distclean): Added actions for
3103 (.c.x): Use guile-snarf.
3104 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
3105 (gen_c_files): Note that these depend on guile-snarf.
3106 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
3107 now in "snarf.h". Added #include "snarf.h" to get them.
3108 * libguile.h: Added #include "snarf.h".
3109 (Patches applied and tweaked by Jim Blandy.)
3111 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3113 * socket.c: Use K&R style declaration for 'close'; the GNU coding
3114 standards suggest against providing prototypes for system
3115 functions. Thanks to Greg Troxel.
3117 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3119 * strports.c (scm_eval_0str): New function.
3120 #include "read.h", to get prototype for scm_read.
3121 * Makefile.in (strports.o): Update dependencies.
3122 * strports.h: New prototype.
3124 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
3125 scheme name from "int?" to "integer?". It seems to do the job.
3126 * numbers.h: Rename prototype too.
3127 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
3130 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
3131 scm_num_eq_p): Rename these according to R4RS conventions: call
3132 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
3133 to making libguile R4RS compliant without ice-9...
3135 * load.c (scm_sys_search_load_path): Search for files under all
3136 extensions listed in the %load-extensions variable. If FILENAME
3137 is absolute, return it unchanged, without searching the load path.
3138 (scm_loc_load_extensions): New variable, pointing to
3139 %load-extensions' value cell.
3140 (scm_init_load): Initialize it, and the value it points to.
3141 (scm_primitive_load_path): Improve error reporting.
3143 * load.c (scm_loc_load_hook): New variable, pointing to value cell
3144 of new Scheme variable %load-hook.
3145 (scm_primitive_load): Apply %load-hook to filename.
3147 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
3149 * configure.in: add tests for figuring out whether buffered data
3150 is available in a FILE structure, which is needed by char-ready.
3152 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
3155 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
3156 exceptions using misc_error instead of syserror. It seems a bit
3157 odd to throw an exception if a string can't be found in the
3158 environment, but it's consistent with open-file, stat etc.
3159 (simpos.h): remove sys_ from getenv.
3161 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
3162 occurs, throw an error instead of returning errno. Return value
3164 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
3166 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
3168 * filesys.c (scm_stat2scm): derive file type and permissions from
3169 the stat mode and append them to the returned vector.
3170 There isn't much overhead in doing this and it avoids the need to
3171 work with S_IRUSR et al. in Scheme.
3172 Define symbols scm_sym_regular etc.
3173 (scm_init_filesys): don't intern S_IRUSR etc.
3175 * load.c: change s_try_load and s_try_load_path to s_primitive_load
3176 and s_primitive_load_path.
3178 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
3180 * error.h: don't declare error symbols. prototype for scm_misc_error.
3182 * stackchk.c (scm_stack_overflow_key): defined here instead of in
3185 * error.c: use SCM_SYMBOL to set up error keys.
3186 scm_misc_error: new procedure.
3188 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3190 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
3191 between `#!' and `!#' is ignored.
3192 (skip_scsh_block_comment): New function.
3194 * feature.c (scm_set_program_arguments): New argument, FIRST.
3195 * feature.h: Update prototype.
3196 * init.c (scm_boot_guile_1): Pass new argument to
3197 scm_set_program_arguments.
3199 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3201 * init.c (scm_start_stack): Don't initialize scm_progargs here.
3202 (scm_boot_guile): Call scm_set_program_arguments here, later than
3203 the old initialization.
3205 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
3206 initialization procedure.
3207 - Delete in, out, err arguments; there are other perfectly good
3208 ways to override these when desired.
3209 - Delete result argument; this function shouldn't ever return.
3210 - Rename init_func argument to main_func, for less confusion.
3211 - Delete boot_cmd argument; main_func is more general.
3212 -Add 'closure' argument, to help people pass data to main_func
3213 without resorting to global variables.
3214 - Abort if reentered; don't bother returning an error code.
3215 - Call scm_init_standard_ports to set up the default/current
3216 standard ports; no need to pass them to scm_start_stack.
3217 - Remove code to evaluate the boot_cmd, and start the repl; let
3218 the user do something like that in main_func if they want.
3219 - Remove code to package up a return value; main_func can do any
3221 - Call exit (0), instead of returning.
3222 (scm_start_stack): Don't initialize the I/O ports here; that's
3223 weird. Delete in, out, err arguments. Move guts to
3224 scm_init_standard_ports, scm_stdio_to_port.
3225 (scm_init_standard_ports): New function, to set up current and
3226 default standard ports.
3227 (scm_start_stack, scm_restart_stack): Make these static.
3228 * init.h (scm_boot_guile): Adjust declaration.
3229 (scm_start_stack, scm_restart_stack): Remove externally
3230 visible declarations for these.
3231 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
3233 * fports.c (scm_stdio_to_port): New function. Its guts used to be
3234 written out several times in scm_start_stack.
3235 * fports.h: New declaration for the above.
3237 * feature.c (scm_set_program_arguments): New function.
3238 * feature.h: New declaration for the above.
3240 * ports.c: Formatting tweak.
3242 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
3244 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
3245 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
3246 for obtaining the address of a car or cdr field. Motivation:
3247 &SCM_CXR make assumptions about the internal structure of the
3250 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
3251 Motivation: see SCM_CXRLOC.
3253 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
3254 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
3255 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
3256 Motivation: Safer use. Some other macros are defined in terms of
3257 these operations. If these are defined using the SCM_SETCXR
3258 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
3259 to inefficiency and an <e1> with side-effects could potentially
3260 break. Also, these particular operations are heavily utilized in
3261 the garbage collector. In unoptimized code there will be a
3264 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
3265 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
3266 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
3267 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
3268 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
3269 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
3270 vports.c: Cleaned up use of pairs: Don't make any special
3271 assumptions about the internal structure of selectors and
3272 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
3273 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
3274 (Among other things, this change makes it easier to build Guile
3275 with certain compilers which have problems with casted lvalues.)
3277 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3279 * stacks.c: Improve selection of relevant stack frames when making
3280 a stack object. Introduce one level of indirection in the stack
3281 object to make it possible to "narrow" to a certain region of the
3282 stack. This facilitates making use of more clever algorithms (not
3283 implemented) for selecting relevant frames and gives a cleaner
3284 design since selection of frames can be done independently of
3285 extraction of frames from the real stack.
3286 (scm_stack_id): Also take #t as argument which means look at
3289 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
3290 Turn n_tail into an integer directly representing current number
3291 of frames in stack. Add field tail.
3293 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
3295 * debug.c (scm_make_memoized): Made it available at scheme level.
3296 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
3297 SCM_NIMP before applying heavier predicates in argument checking.
3298 (scm_local_eval): Also take memoized object as argument.
3300 * backtrace.c (scm_display_error): Just a safety measure: Stacks
3301 aren't created with zero length, but should such a strange
3302 creature suddenly turn up...
3304 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
3306 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
3307 `del', for the sake of C++ compilers. (Patch applied by JimB.)
3309 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
3311 * variable.c (scm_make_variable): Make the name hint optional, as
3313 (anonymous_variable_sym): Renamed from variable_sym. All uses
3316 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
3317 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
3318 of scm_primitive_load_path was also changed to
3319 "primitive-load-path", from "%try-load-path". Callers changed.
3320 We'd like to respect the convention that a function named
3321 "try-mumble" should behave just like the function called "mumble",
3322 but return #f instead of signalling some error.
3323 * load.h: Rename prototypes.
3325 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3327 * print.c (make_print_state, grow_print_state), print.h: Modified
3328 the print state representation: Don't use a tail array for
3329 recording of circular references. Resizing of the print state
3330 structure invalidates the print state pointer. To avoid passing
3331 around an indirect print state reference to all printing
3332 functions, we instead let the print state reference a resizable
3335 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3337 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
3338 Don't crash when passed an improper list terminated by a
3339 non-immediate value.
3341 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
3343 Allocate data for structures on an eight-byte boundary, as
3344 required by the tagging system.
3345 * struct.c (alloc_struct): New function.
3346 (scm_make_struct, scm_make_vtable_vtable): Call it.
3347 * struct.h (scm_struct_n_extra_words): Bump to 3.
3348 (scm_struct_i_ptr): New "field".
3349 * gc.c (scm_gc_sweep): When we need to free the data, use the
3350 information stored by alloc_struct to find the beginning of the
3351 block allocated to the structure, so we can free it.
3353 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3355 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
3358 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
3359 (scm_debug_info): New member: id.
3361 * stacks.c: Stacks are now represented as structs; Stacks have an
3362 id given to them by `start-stack'.
3363 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
3365 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
3366 Changed stack representation.
3368 * debug.c (scm_procedure_name): Try procedure property `name' for
3369 compiled closures aswell.

3375 objects. (Earlier, only closures were recorded.)
3377 * procprop.h: Added declaration of scm_i_name.
3379 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
3380 (scm_make_gsubr): Record names of compiled closures.
3382 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3384 * debug.c, debug.h: Removed obsolete code.
3386 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
3387 stacks.c: Renamed regs --> scm_contregs.
3389 * print.c (scm_free_print_state): Cleanup print state before
3390 returning it to pool. It is better to do it here than in
3391 scm_prin1 since scm_prin1 is called often.
3393 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
3394 s_set_source_property_x): Check that first argument is a pair or a
3397 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
3398 scm_i_line, scm_i_column and scm_i_breakpoint global.
3400 * init.c: Added #include "backtrace.h" and #include "stacks.h".
3401 (scm_boot_guile_1): Added calls to scm_init_backtrace and

3411 backtrace.h, stacks.c and stacks.h.
3413 * symbols.c (scm_sym2ovcell): Fixed documentation.
3415 * _scm.h (min, max): Added.
3417 * async.c: Moved `min' macro to _scm.h.
3419 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
3420 SCM_BACKTRACE_INDENT.
3422 * eval.c: Added new debug options `maxdepth' and `indent'.

3431 * print.h: Added declarations for scm_make_print_state,
3432 scm_free_print_state.
3434 * debug.c (scm_m_start_stack): New acro.
3436 * debug.h: Small cleanup.
3438 * init.c (scm_boot_guile_1): Moved scm_init_debug below

3461 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
3462 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
3463 declare functions with prototypes. (Patch thanks to Marius
3466 More prototype-related changes from Marius Vollmer:
3467 * gdb_interface.h: Wrapped header file in #ifdef/#endif
3468 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
3469 * ports.h (ptobfuns): Added prototypes. This means some casting in
3471 * fports.c: Added casts for initializations, since the functions
3472 are defined to take FILE * as their stream argument, not SCM.
3473 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
3474 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
3475 to `char *str_data' to conform to prototype.
3477 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3479 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
3481 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
3483 * stime.c, stime.h: use SCM_P method.
3485 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
3487 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
3488 be given at least two arguments. Insist that lst's last element
3489 be a list, but don't make any requirements of its predecessors.
3491 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
3493 * eval.c (scm_nconc2last): Revert last change; there seems to be
3494 other stuff going on here.
3496 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
3498 * eval.c (scm_nconc2last): Make sure that each element of lst
3499 (which is a list of argument lists, except for the tail) is a
3500 proper list, i.e., finite and terminated by '().
3502 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3504 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
3507 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
3508 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
3511 * vectors.c (scm_make_vector): Fill vectors with the undefined
3512 value, to help make Guile Scheme code more portable to other
3515 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
3516 * symbols.h, tags.h: Doc fixes.
3518 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
3520 * async.c (scm_take_signal): Doc fixes.
3522 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
3524 * numbers.c (scm_divbigint): When the remainder is zero, we don't
3525 want to subtract it from the modulus; we just want to leave it
3528 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
3530 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
3533 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
3535 * throw.c (scm_catch_apply): Finished implementation of
3538 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3540 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
3542 (scm_init_filesys): set "i/o-extensions" feature.
3545 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
3547 * Makefile.in (root.o): Correct dependencies.
3549 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
3551 * Makefile.in: Added dependency entry for root.o.
3553 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
3554 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
3556 * init.c (scm_start_stack): Set initial root continuation number
3559 * procs.c: New function: scm_thunk_p.
3561 * procs.h: Added declarations of scm_thunk_p.
3563 * root.c: Renamed `call-with-new-root' -->
3564 `call-with-dynamic-root'.
3565 (cwdr): Removed allocation of new root state. This should be done
3566 separately by use of scm_make_root.
3567 (scm_apply_with_dynamic_root): New function: Does what it
3568 sounds like. Needed when spawning threads.
3570 * root.h: Added member last_debug_frame to root state.
3571 Added #include "libguile/debug.h"
3573 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
3574 arguments. The motivation is that code in root.c needs catch
3575 functionality, and we want to avoid code duplication.
3576 New functions: scm_catch, scm_lazy_catch. These are wrappers for
3577 scm_catch_apply. scm_lazy_catch is intended to introduce catch
3578 handlers that run without popping the stack into the dynwind
3581 * throw.h: Added prototypes for scm_catch_apply and
3584 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3586 * root.h (scm_root, scm_set_root): Decouple thread support details
3587 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
3588 SCM_SET_THREAD_LOCAL_DATA.
3590 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
3591 and tortoise scanning loop.
3593 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
3595 * Makefile.in: Rebuild dependencies.
3597 * libguile.h: #include "libguile/print.h" before "smob.h", since
3598 the latter uses the print_state structure.
3600 * throw.c (scm_ithrow): Use the correct variable when checking to
3601 see if a given element of scm_dynwinds is a valid catch.
3603 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
3604 structure, abort; don't just silently ignore the garbage.
3606 * _scm.h: #include "print.h" here, since it seems to be used just
3608 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
3609 strports.c, unif.h: Don't #include "print.h".
3611 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3613 * feature.h (scm_loc_features): Removed external declaration.
3614 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
3616 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3618 * feature.c (scm_init_feature): Added threads feature (needs to be
3619 initialized here, since features doesn't exist when
3620 scm_init_threads is called).
3622 * libguile.h: Added #include "libguile/../threads/threads.h".
3623 (This is a kludge to get thread support working. This should be
3626 * configure.in, acconfig.h: Added flags for thread support.
3628 * scmsigs.c: Define `signal' to be `pthread_signal' if using
3631 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
3632 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
3635 * _scm.h: Added conditional #include "threads.h"
3637 * __scm.h (SCM_ASYNC_TICK): Added call to macro
3638 SCM_THREADS_SWITCHING_CODE.
3640 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
3641 allocate the basic dynamic root object.
3642 (scm_boot_guile): Added call to scm_init_root.
3644 * root.c, root.h: Added root smob.
3645 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
3646 functions: Implements dynamic roots mostly according to spec in
3647 SCM manual. Main difference is that the second argument is a
3648 throw handler rather than an error "thunk".
3650 * root.h: Added declaration of scm_init_root.
3652 * root.c: Added #include "genio.h", #include "smob.h", #include
3653 "pairs.h", #include "throw.h", #include "dynwind.h", #include
3655 (scm_init_root): Added #include "root.x".
3657 * throw.c: Added #include "stackchk.h"
3658 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
3659 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
3660 can be used in scm_call_with_new_root; Added reenabling of stack
3661 checking when catching a throw.
3663 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
3665 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
3667 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
3668 element is not found, as per R4RS.
3670 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
3672 * list.c: Doc fixes throughout.
3674 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3676 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
3677 declare the char * to be const. Avoids a warning in rgx.c.
3679 * ports.h: spelling fix.
3681 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
3684 * load.c (scm_sys_try_load_path): throw an error if file not found
3685 (like it says it in NEWS).
3687 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
3689 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
3690 PROPS slot to '(), not #f; it's an empty alist.
3692 * throw.h, throw.c: Use SCM_P instead of #if hair.
3694 Remove special support for uncaught throws; see throw.c for
3696 * throw.c (uncaught_throw): New function.
3697 (scm_ithrow): Call uncaught_throw if we don't find a throw
3698 target; don't mess with scm_bad_throw_vcell.
3699 (scm_bad_throw_vcell): Variable deleted.
3700 (scm_init_throw): Don't initialize it.
3702 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
3705 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3707 * numbers.c (scm_istr2int): If the number is short (as most
3708 numbers are), just call scm_small_istr2int to deal with it.
3709 (scm_small_istr2int): New function, created by un-#ifdefing the
3710 non-bignum version of scm_istr2int and renaming it.
3712 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
3714 * load.c (scm_sys_try_load): don't check whether value returned
3715 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
3716 Change the Scheme name from %try-load to primitive-load.
3718 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
3719 Can avoid passing a message, allowing it to be derived in the
3720 error handler (e.g., if we want to throw to the key both from
3723 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
3725 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
3726 references now have a new appearance which is more compact and
3727 also gives a clue about what the target of the reference is.
3728 By setting parameters in the print state, more fancy printing can
3729 be achieved. This is used by the (not yet commited) backtrace
3732 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
3734 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
3737 * print.c: Added #include "struct.h". Removed function
3740 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
3741 scm_iprin1. Removed prototype for scm_prlist.
3743 * arbiters.c (prinarb),
3744 async.c (print_async),
3745 debug.c (prindebugobj, prinmemoized),
3746 eval.c (prinprom, prinmacro),
3747 filesys.c (scm_fd_print, scm_dir_print),
3749 mallocs.c (prinmalloc),
3750 numbers.c, numbers.h (scm_floprint, scm_bigprint),
3751 smob.h (scm_smobfuns),
3752 srcprop.c (prinsrcprops),
3754 unif.c, unif.h (scm_raprin1, rapr1),
3755 variable.c (prin_var): Changed argument `int writing' to
3756 `scm_print_state *pstate'.
3758 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
3759 that it will be called before scm_init_print.
3761 * print.c (scm_prin1): Print states are now allocated when calling
3762 scm_prin1 and then passed around to all printing functions as an
3763 argument. A cache `print_state_pool' enables reuse of print
3765 (scm_make_print_state): New function.
3766 (scm_iprin1): Adaption to print states.
3767 (scm_iprlist): An initial "hare and tortoise" scan brings down
3768 time complexity to O (depth * N). (Better time complexity will be
3769 achieved when the printing code is completely rewritten.)
3771 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3773 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
3774 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
3775 it gets done whether or not the cache variable has a value.
3777 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3779 Distinguish #f and ().
3780 * __scm.h: #undef SICP.
3781 * pairs.h (SCM_EOL): Delete this definition, equating it with
3783 * tags.h (SCM_EOL): Give it a new definition here; I think I found
3784 the value it used to have. Doc fixes, too.
3786 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
3788 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
3789 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
3790 Lord's implementation of structs, allowing for tail arrays as
3791 described in the manual. Also fixed some bugs. (Both the interface
3792 and the implementation should be improved.)
3794 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
3796 * print.c, print.h: Closures now print like #<procedure foo (x)>.
3797 People who whish to see the source can do `(print-enable 'source)'.
3798 Removed #ifdef DEBUG_EXTENSIONS.
3800 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3802 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
3803 integer (assuming for now accepting an integer is a good thing).
3805 * error.c, fports.c: replace use of %S in lgh_error args with %s.
3806 %S will be used instead for write'ing arguments.
3808 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
3809 asserts. fix a few other asserts.
3810 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
3811 scm_uniform_vector_ref, scm_array_set_x,
3812 scm_dimensions_to_unform_array): change args in
3813 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
3814 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
3815 scm_substring_fill_x): likewise.
3816 gsubr.c (scm_gsubr_apply): likewise.
3817 eval.c (SCM_APPLY): likewise.
3819 * eval.c (4 places): replace scm_everr with lgh_error or
3822 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
3823 scm_memory_error): new procedures.
3824 scm_everr: deleted. can use scm_wta, dropping first two args.
3825 scm_error: convert NULL subr to SCM_BOOL_F.
3827 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
3830 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
3833 * error.c, error.h: new error keys: scm_arg_type_key,
3834 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
3836 scm_wta: reimplement using lgh_error instead of scm_everr.
3838 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
3840 * gdbint.c: scm_lread now has one more argument.
3842 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
3843 scm_port_\1; Added mutator scm_set_port_filename_x (used when
3844 loading source from non-file ports, which, e. g., happens when
3845 using the Emacs interface).
3847 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
3850 * read.c: Added code for recording of positions of source code
3851 expressions; New functions: recsexpr, scm_lreadrecparen;
3852 _scm_make_srcprops --> scm_make_srcprops
3853 (scm_flush_ws): Removed updating of positions counters. This work
3854 is already done by scm_gen_getc
3856 * read.h: Added prototype for scm_lreadrecparen
3858 * print.c: Added #include "alist.h"
3860 * eval.c: Added #include "hash.h"
3862 * eq.c: Added #include "ramap.h"
3864 * options.c: Documentation fixes.
3866 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
3867 (scm_init_srcprop): Adjusted size of initial source-whash. Name
3868 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
3869 --> scm_make_srcprops
3871 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
3872 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
3873 function calls in the definition of the whash access macros.
3875 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
3877 * init.c (scm_boot_guile): Add level of indirection to
3878 scm_boot_guile_1() to ensure that stack base pointer is properly
3879 initialized. There was no guarantee that variable i was the
3880 highest/lowest variable on stack (i.e. the call frame of
3881 scm_boot_guile was not completely protected from gc).
3883 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
3885 * ports.h (scm_port_table): put back file_name, it will be used to
3886 support debugging. Undo related changes in fports.c, ioext.c,
3889 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3891 * ports.h (scm_port_table): remove file_name member for now, it seems
3893 * fports.c (scm_open_file): don't set file_name in PTAB.
3894 (prinfport): don't use file_name in PTAB.
3895 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
3896 * ports.c (scm_add_to_port_table): don't intialize file_name.
3897 (scm_port_file_name): remove for now.
3898 * gc.c (scm_gc_mark): don't mark PTAB file_name.
3900 * fports.h (scm_mkfile): prototype deleted.
3901 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
3903 * debug.c, unif.c: use scm_out_of_range instead of
3904 wta for range errors (ASSERT still needs work).
3906 * error.c, error.h (scm_out_of_range): new procedure.
3908 * error.c, error.h (scm_out_of_range_key): new key.
3910 * posix.c (scm_sync): #else was missing.
3912 * error.c, error.h: append _key to names scm_num_overflow and
3915 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
3916 of consing an empty list.
3917 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
3918 of macros, saves code and string space.
3919 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
3920 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
3921 lower case. Rename scm_syserror_m to scm_syserror_msg.
3922 error.h: prototypes for new procedures.
3924 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
3926 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
3928 * error.c, error.h: setup scm_num_overflow key.
3930 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
3931 Remove definition of SCM_OVSCM_FLOW.
3933 * fports.c (scm_open_file): use SCM_SYSERROR_M.
3935 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
3936 explicit message and args.
3938 * error.c, error.h, __scm.h: change system_error_sym to
3941 * error.c (system_error_sym): remove leading %% from the Scheme name
3944 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
3946 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3948 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
3949 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
3950 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
3951 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
3952 renamed. (These were introduced by unsupervised name
3955 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3957 * print.c: Added code for detection of circular references during
3958 printing. (init_ref_stack, grow_ref_stack): New functions. Added
3959 a hook for printing of closures (accessible via print options).
3960 This leads to a split of calls to scm_iprin1 into two classes:
3961 elementary print operations (e. g. the code which prints a smob)
3962 still use scm_iprin1 while top level calls (like scm_display) use
3963 scm_prin1. scm_prin1 begins by clearing the data structure used
3964 to record reference information.
3966 * print.h: Added declarations of scm_prin1 and scm_prlist.
3968 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
3970 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
3972 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
3974 * error.c (err_head): scm_iprin1 --> scm_prin1
3976 * debug.c: Adjusted header comment.
3980 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
3982 * strerror.c: Doc fix.
3984 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3986 * gdbint.c (gdb_read): Now possible to run during GC.
3987 (unmark_port, remark_port): New functions.
3989 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
3991 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
3992 of allocating a new string object. Also, increase size by
3993 the factor 2 instead of 1.5.
3995 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
3997 * __scm.h (SCM_P): Corrected to run under traditional C.
3999 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4002 * async.c: Calls to scm_sysintern corrected.
4004 * async.h (scm_async_clock): Redundant declaration removed.
4006 * continuations.c (scm_dynthrow): Redundant declaration removed.
4008 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4009 Definition typos corrected.
4011 * debug.h: Missing declarations of functions in debug.c added
4014 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4015 Missing declarations to functions in eval.c added.
4017 * filesys.c: Possibly uninitialized variable rv.
4019 * gc.h (scm_object_addr, scm_unhash_name): Missing
4020 declarations of functions defined in gc.c added.
4022 * genio.c: Possible typos str_data -> wstr_data. ???
4024 * genio.c: Possibly unintended shadowing of local variable
4025 `int c' (gotos out of scope of inner `c'). ???
4027 * init.c: Uninitialized `SCM last' may be used.
4029 * ioext.h: (scm_sys_isatty_p): Typo.
4031 * list.h (scm_list_head): Missing prototype for function in
4034 * numbers.c (scm_two_doubles): Changed from extern to static
4035 (is used only within numbers.c).
4037 * numbers.h: Repeated declarations removed.
4039 * ports.h (scm_close_all_ports_except): Declaration for the
4040 function defined in ports.c added.
4042 * posix.h: Missing declarations added.
4044 * procs.h (scm_make_subr_opt): Missing declaration added.
4046 * socket.h (scm_sys_gethost): Missing declaration added.
4048 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4050 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
4051 Missing declarations added.
4053 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
4055 * struct.c: Uninitialized variable `SCM answer' may be used.
4057 * unif.c (l2ra): Declaration prototype.
4059 * unif.c (scm_array_equal_p): Dummy definition removed (it is
4060 defined in ramap.c).
4062 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
4063 Redundant declarations removed (they are in ramap.h).
4065 * variable.h (scm_make_udvariable,
4066 scm_make_undefined_variable): Declaration corrected to
4067 correspond variable.c.
4069 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
4070 Missing declarations added.
4072 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
4074 * Makefile.in (distclean): Don't forget to delete fd.h.
4076 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4078 * fd.h.in, tags.h: Trivial cleanups.
4080 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
4081 marksweep.h just declared functions from gc.c.
4082 * gc.h, libguile.h: Don't #include "marksweep.h".
4083 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4084 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
4085 dependencies updated.
4087 * libguile.h: Don't #include "files.h"; it's been deleted.
4089 * files.c (scm_sys_delete_file): Moved to filesys.c.
4090 File is now empty; deleted.
4092 * filesys.c: scm_sys_delete_file is now here. Remove
4093 #if's; they seem to rely on remnants of an old portability
4094 regimen. If the problems come up again, solve them properly,
4095 using autoconf. Specifically: Don't test M_SYSV, and #define
4096 remove to be unlink if it's #defined; don't use remove just
4097 because HAVE_STDC_HEADERS is #defined.
4098 * filesys.h: Add declarations for scm_sys_delete_file.
4099 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4100 files.o, files.h, files.c, and files.x.
4101 * init.c: Don't #include "files.h", and don't call scm_init_files.
4103 Use SCM_P instead of PROTO; the latter intrudes on the user's
4105 * params.h: Deleted; definition of SCM_P moved to...
4106 * __scm.h: ... here, where it replaces PROTO macro.
4107 * libguile.h, smob.h: Don't #include "params.h".
4108 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
4109 smob.h: Fix prototypes accordingly.
4110 * Makefile.in: Update dependencies.
4111 (inner_h_files): Remove params.h.
4113 * gc.c: #include "gc.h"; every module should include its header,
4114 to let the compiler cross-check the declarations against the
4117 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
4118 simpos.h: #include "libguile/__scm.h".
4120 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
4122 * init.c: Don't forget to #include smob.h and init.h.
4123 * Makefile.in: Dependencies updated.
4125 * smob.h: Use PROTO instead of #if __STDC__.
4127 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
4129 * __scm.h: Doc fixes.
4131 * __scm.h, libguile.h: Use "quotes" in the #includes, not
4132 <angles>; this allows `make depends' to work properly.
4134 * libguile.h: #include smob.h and pairs.h before the others; they
4135 define typedefs used by other headers.
4137 C files should #include only the header files they need, not
4138 libguile.h (which #includes all the header files); the pointless
4139 recompilation was wasting my time.
4140 * Makefile.in (all .o dependency lists): Regenerated.
4141 * libguile.h: Don't try to get a definition for size_t here...
4142 * __scm.h: Do it here.
4143 * _scm.h: Since this is the internal libguile header, put things
4144 here that all (or a majority) of the libguile files will want.
4145 Don't #include <libguile.h> here; that generates dependencies on
4146 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
4147 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
4148 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

4245 * weaks.c: Get "weaks.h".
4247 * stackchk.h: #include "libguile/debug.h",
4249 * print.h, read.h: #include "options.h", since everyone who uses
4250 either of these files will need that.
4252 * smob.h: #include "ports.h", "genio.h", and "print.h", since
4253 anyone who uses this file will need them to define the smob
4254 printing functions. Also, get markers.h, since people will need
4255 to #define the mark functions.
4257 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
4258 * ports.h: ... to here.
4260 * ports.h (scm_port_table_size): Explicitly give type as 'int';
4261 don't rely on archaic C default type rules.
4263 * fports.h: #include "libguile/ports.h", since you need that in
4264 order to parse this.
4266 * genio.h: #include "libguile/print.h", because you need that to
4267 parse this; don't bother #including "ports.h", since print.h gets
4270 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
4272 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
4273 this; it's now a reference to an element of *scm_root.
4275 * debug.h: Don't #include "options.h"; the compiler won't be able
4276 to find that once the headers are installed; instead, #include
4277 "libguile/options.h".
4278 * gc.h: Same, with marksweep.h.
4279 * mbstrings.h: Same, with symbols.h.
4280 * scmhob.h: Same, with _scm.h.
4281 * smob.h: Same, with params.h.
4283 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
4284 C files; there's no need for this, and it forces recompilations
4287 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
4289 * error.c (scm_error): declare scm_error_callback.
4291 * error.h: prototype for scm_error_callback.
4293 * __scm.h: define lgh_error.
4294 (SCM_SYSERROR): redefine using lgh_error.
4296 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
4298 * error.c (scm_error): new procedure.
4300 * error.h: prototype for scm_error.
4302 * Makefile.in (install): install scmconfig.h from the current
4303 directory, not $(srcdir).
4305 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4307 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4308 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
4309 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
4310 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
4311 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
4312 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
4313 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
4314 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
4315 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
4316 vports.h, weaks.h: #include "libguile/__scm.h", not
4317 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
4318 dependencies are within libguile properly.
4320 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4322 * Makefile.in (.c.x): Simplify; there's no need to run this rule
4323 when scmconfig.h doesn't exist.
4325 * load.c (scm_sys_try_load): Correct spelling.
4327 * feature.c (scm_loc_features): Make this static.
4329 * Makefile.in (libpath.h): Omit trailing slash from path. We
4330 shouldn't require it of users, so why put it here?
4332 Move code to initialize and search %load-path from ice-9 to C
4333 code, so we can use the load-path to find the ice-9 boot code;
4334 this makes it easier to run Guile without installing it. See
4335 corresponding changes in guile/Makefile.in.
4336 * feature.c: Move stuff concerned with the load path to load.c.
4337 (scm_compiled_library_path): Deleted.
4338 Don't #include libpath.h here.
4339 * feature.h: Don't mention scm_compiled_library_path.
4340 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
4341 <sys/stat.h>, and <unistd.h> (if present).
4342 (R_OK): #define if the system hasn't deigned to.
4343 (scm_loc_load_path): New variable.
4344 (scm_init_load_path, scm_sys_search_load_path,
4345 scm_sys_try_load_path): New functions.
4346 (scm_init_load): Initialize scm_loc_load_path to point to the
4347 value cell of the Scheme %load-path variable.
4348 * load.h: Add declarations for scm_sys_search_load_path,
4349 scm_sys_try_load_path.
4350 * init.c: Call scm_init_load_path.
4351 * Makefile.in (feature.o, load.o): Dependencies updated.
4353 * load.c, load.h: Rewrite using PROTO macro.
4355 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4357 * gc.c (scm_cellp): New function: C predicate to determine if an
4358 SCM value can be regarded as a pointer to a cell on the heap.
4360 * gc.h: Added declaration of scm_cellp.
4362 * gdb_interface.h: New file: The GDB interface header from the GDB
4365 * gdbint.c: New file: GDB interface.
4367 * gdbint.h: New file: GDB interface.
4369 * libguile.h: Added #include <libguile/gdbint.h>.
4371 * init.c (scm_boot_guile): Added scm_init_gdbint.
4373 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
4374 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
4375 found if object files and source are kept separate).
4377 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
4379 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
4381 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
4383 * configure.in: Don't substitute the values of TCL_SRC_DIR and
4384 TK_SRC_DIR; they're not relevant any more.
4386 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
4387 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
4389 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
4391 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
4392 search path, so we can find the <libguile/MUMBLE.h> headers.
4394 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
4396 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
4397 implicit in the .c.o rule.
4398 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
4401 Put the library path in a header file, instead of passing it on
4402 the command line in every compilation.
4403 * Makefile.in (libpath.h): New target.
4404 (feature.o): Depend on libpath.h.
4405 (clean): Delete libpath.h.
4406 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
4407 * feature.c: ... #include "libpath.h" here.
4408 * .cvsignore: Ignore libpath.h.
4410 Don't install the unwashed masses of Guile header files in the
4411 main #include path; put most of them in a subdirectory called
4412 'libguile'. This avoids naming conflicts between Guile header
4413 files and system header files (of which there were a few).
4414 * Makefile.in (pkgincludedir): Deleted.
4415 (innerincludedir): New variable; this and $(includedir) are enough.
4416 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
4417 (installed_h_files): Divide this up. Now this variable lists
4418 those header files which should go into $(includedir) (i.e. appear
4419 directly in the #include path), and ...
4420 (inner_h_files): ... this new variable says which files appear in
4421 a subdirectory, and are referred to as <libguile/mumble.h>.
4422 (h_files): List them both.
4423 (install): Create innerincludedir, not pkgincludedir. Put
4424 the installed_h_files and inner_h_files in their proper places.
4425 (uninstall): Corresponding changes.
4426 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4427 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
4428 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
4429 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
4430 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
4431 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
4432 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
4433 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
4434 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
4435 vports.h, weaks.h: Find __scm.h in its new location.
4436 * __scm.h: Find scmconfig.h and tags.h in their new locations
4437 (they're both "inner" files).
4439 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
4441 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
4443 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4445 * posix.c: Doc fixes.
4447 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
4449 * socket.c: Don't include a prototype for inet_aton; just use a
4450 K&R style declaration, to avoid warnings but minimize the chance
4451 of conflicts with the system.
4453 On NextStep, <utime.h> doesn't define struct utime, unless we
4454 #define _POSIX_SOURCE before #including it.
4455 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
4456 * acconfig.h: New comment text for above CPP symbol.
4457 * configure.in: Call it.
4458 * posix.c: #define _POSIX_SOURCE if it seems necessary.
4460 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
4462 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
4463 testing for __EMX__.
4465 * posix.c: #include <libc.h>, if it exists.
4467 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
4468 don't even know if the latter exists.
4470 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
4471 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
4472 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
4474 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
4476 (scm_init_posix): Use them when initializing the Scheme constants
4479 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4481 * Makefile.in (libdir, includedir, bindir): Use the
4482 autoconf-supplied values, instead of deriving them ourselves.
4483 (pkgincludedir, datadir, pkgdatadir): New variables.
4484 (install, uninstall): Put the header files in a special
4485 subdirectory, not in the main search path.
4487 * Makefile.in (ALL_CFLAGS): Provide the proper value for
4488 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
4490 * Makefile.in (IMPLPATH): Deleted; never used.
4492 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
4493 on the Tcl/Tk source any more.
4494 (INCLUDE_CFLAGS): Remove references to the above.
4496 * Makefile.in (version.o): Corrected dependencies.
4498 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
4500 * libguile.h: #include "version.h"
4502 * init.c (scm_boot_guile): Call scm_init_version.
4503 * gscm.c (gscm_run_scm): Call scm_init_version.
4505 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
4506 GUILE_VERSION): AC_DEFINE these.
4507 (acconfig.h): #undef the above symbols.
4509 * Makefile.in (libobjs): Add version.o.
4510 (installed_h_files): Add version.h.
4511 (c_files): Add version.c.
4512 (gen_c_files): Add version.x.
4513 (version.o): New rule.
4514 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
4515 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
4516 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
4517 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
4518 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
4519 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
4520 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
4521 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
4522 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
4523 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
4524 weaks.o): Add version.h to dependency lists.
4525 (markers.o): Remove duplicate rule.
4527 * version.h: New file.
4529 * version.c: New file.
4531 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4533 * symbols.c (scm_strhash): scm_downcase is now a function, not an
4534 array; use it appropriately. Since GCC is quite happy to
4535 subscript functions, it never warned us about this; we should use
4536 -Wpointer-arith in the future. I guess we never tested
4539 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4541 * socket.c: Doc and copyright fixes.
4543 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4545 * debug.c: Fixed and improved gdb support.
4547 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4549 * socket.c: Added declaration of inet_aton to avoid compiler
4550 warning. (Hope this solution is correct.)
4552 * stime.c: Added declaration of ftime. (This is missing in
4555 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
4557 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
4559 * Makefile.in (c_files): add strerror.c.
4561 * strerror.c: new file from Emacs' sysdep.c.
4562 maybe configure should also check for sys_errlist.
4564 * configure.in (AC_REPLACE_FUNCS): add strerror.
4566 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4568 * debug.c (scm_init_debug): Added initialization for
4569 scm_evaluator_traps.
4571 * debug.h, debug.c: Various name changes.
4572 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
4573 "debug-options-interface". See commentary in options.c.
4575 * options.h, options.c: Options now have documentation strings.
4576 Also added a long explanatory commentary.
4578 * eval.c, print.h, print.c, read.h, read.c: Modifications to
4581 * gscm.c, init.c, root.c, throw.c: Bug fixes:
4582 last_debug_info_frame is now updated in all cases.
4584 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
4587 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4589 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
4590 Added option STACK_CHECKING.
4592 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4594 * Makefile.in: Added {debug,options,srcprop}.{h,c}
4596 * __scm.h: Removed symbols for debugging support.
4598 * acconfig.h: Added symbols for debugging support.
4600 * configure.in: Added user option for debugging support.
4601 --enable-debug will include the debugging code into libguile.a.
4603 * continuations.c (scm_make_cont): Enlarged the #if 0 around
4604 scm_relocate_chunk_to_heap.
4606 * debug.c: New file: low-level debugging support. It also
4607 includes support for debugging with gdb. (The extensions to gdb
4608 are written by Per Bothner at Cygnus.)
4610 * debug.h: New file: low-level debugging support.
4612 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
4613 argument pairs. Extensive modifications to the debugging
4614 evaluator. Added "SECTION:" commentaries to clarify what happens
4615 when, during double compilation. Renamed EVALIMP --> EVALIM.
4616 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
4617 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
4618 the beginning of the file. New procedure: scm_unmemocopy.
4619 Added some global state variables needed by the debugging
4620 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
4621 check_entry, check_apply, check_exit, debug_options and
4622 evaluator_traps. New acro: undefine.
4624 * eval.h: Renamed EVAL --> XEVAL.
4626 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
4627 --> scm_make_weak_key_hash_table.
4629 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
4630 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
4632 * libguile.h: Conditionally include debug.h
4634 * objprop.c (scm_object_properties, scm_set_object_properties_x):
4635 scm_object_properties shouldn't return handle. `handle' now gets
4636 initialized in scm_set_object_properties_x. scm_object_properties
4637 doesn't any longer create an entry in scm_object_whash.
4639 * options.c: New file: handling of run time options.
4641 * options.h: New file: handling of run time options.
4643 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
4645 * print.c: New procedure: scm_print_options
4647 * print.h: Defines for print options.
4649 * read.c: New procedure: scm_read_options
4651 * read.h: Defines for reader options.
4653 * root.h: Added scm_source_whash among scm_sys_protects.
4655 * srcprop.c: New file: source properties.
4657 * srcprop.h: New file: source properties.
4659 * throw.c (jbsmob): Jump buffers are now correctly allocated.
4660 (Bug found by A. Green.)
4662 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
4664 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
4666 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
4668 * libguile.h: #include "objprop.h"; I guess this was forgotten.
4670 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
4671 and should be called by the final client.
4673 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
4675 * gc.h: Use the PROTO macro when declaring functions.
4676 * gc.c: Use the PROTO macro when declaring static functions.
4677 Remove the CPP hair around function definitions.
4679 * gc.c (scm_init_storage): Initialize scm_asyncs.
4681 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
4682 preprocessor symbol; "__scm.h" is where it might get #defined.
4683 * __scm.h: Similar: #include <scmconfig.h> before testing
4686 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
4688 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
4690 * init.c (scm_boot_guile): Add init_func argument; call
4691 (*init_func) instead of calling scm_appinit; it's ucky to
4692 hard-code names for the user's procedures.
4693 * init.h (scm_boot_guile): Adjust declaration.
4695 * __scm.h (PROTO): New macro, for declaring functions with
4698 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
4699 eliminate all the __STDC__ conditionals.
4700 (scm_boot_guile): Add declaration.
4701 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
4702 Remove __STDC__ conditionals around function definitions; the
4703 declarations in init.h will provide the same information, more
4706 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
4707 complain about it in the error message; the error message is
4708 adequate without that note, and there's nothing the user can do
4711 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
4713 * Makefile.in (ancillary): Drop def.sed.
4715 * posix.c (scm_init_posix): Use numeric values, rather than
4716 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
4717 F_OK. The symbols aren't available on some systems, and I'm
4718 pretty sure their values are fixed by common widespread practice.
4719 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
4721 More functions unavailable on some systems.
4722 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
4723 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
4725 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
4726 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
4727 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
4728 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
4729 stub that signals an error as the #else.
4731 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
4733 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
4735 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
4737 * unif.c: include ramap.h.
4739 * read.c (endif): case_insensative_p renamed case_insensitive_p.
4741 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
4743 * ports.c: include sys/ioctl.h.
4745 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
4747 * configure.in: check for sys/ioctl.h.
4749 * ports.c: include <malloc.h> not "malloc.h".
4751 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
4753 * fports.c: remove ttyname and tmpnam declarations.
4755 * posix.c: fewer ttyname declarations.
4757 * fports.c: include <string.h> not "string.h".
4759 * init.c, ioext.c: include string.h and unistd.h.
4761 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
4763 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
4764 genio.c, simpos.c, vports.c: include string.h.
4766 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
4768 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
4770 (scm_addr_buffer_size): change type from scm_sizet to int.
4771 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
4772 from scm_sizet to int.
4774 * error.c: include unistd.h.
4776 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
4779 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
4781 * __scm.hd, def.sed: deleted.
4783 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
4785 Changes for NeXT, suggested by Robert Brown.
4786 * configure.in: Call AC_TYPE_MODE_T.
4787 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
4788 NeXT. Put header file list in alphabetical order.
4789 * configure, scmconfig.h.in: Regenerated.
4790 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
4792 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
4795 * acconfig.h: New file, providing documentation for the CPP
4796 symbols defined in configure.in
4797 * acconfig-1.5.h: Removed; superceded by the above.
4799 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
4801 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
4803 * fports.c (scm_open_file): don't return #f, throw error.
4805 * ioext.c (fileno): renamed from %fileno.
4806 (soft-fileno): deleted.
4808 * ports.c (scm_port_revealed): don't need to check for -1 from
4810 (scm_set_port_revealed_x): return unspecified, not #f.
4812 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
4814 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
4816 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
4818 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
4820 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4822 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
4823 This is necessary on Ultrix, and doesn't hurt portability.
4825 * Makefile.in (dist-dir): New target, implementing a new dist system.
4826 (installed_h_files): Put in alphabetical order.
4827 Remove duplicate entries for markers.h and unif.h.
4828 (c_files): Remove duplicate entries for markers.c.
4829 (ancillary): Renamed from anillery; all uses changed. Remove
4830 PLUGIN; it's a directory, and needs special treatment in dist-dir.
4831 Remove all the ../doc/* files; doc/Makefile.in handles that.
4833 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
4835 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
4836 every if must have an else, or else the whole command has a
4837 non-zero exit code whenever the if's condition is false.
4839 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>

4901 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
4903 * ports.c (scm_ports_prehistory): size malloced here doesn't
4904 matter so long as it is non-0 (got rid of "* 4").
4906 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
4908 * gscm.h: gscm_mkarray eliminated (presumably was not being used
4909 since its definition was bogus).
4911 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
4913 * mallocs.[ch]: back again (for rx at least).
4915 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
4917 * ports.c: removed functions relating to the mapping between ports
4918 and descriptors. (That stuff is unix-specific and should be collected
4919 in a separate library).
4921 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
4922 (Tom Mckay@avanticorp.com)
4924 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
4926 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
4927 handled correctly (SCM_FREEP was applied to them) -- test for
4928 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
4929 being overwritten with #f. (brown@grettir.bibliotech.com)

4983 * ports.c (scm_add_to_port_table): Added fields
4984 to port table entries: file_name, line_num, col.
4985 Update these in open_file, gen_getc and gen_ungetc.
4986 Added procedures to access those fields.
4988 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>

5096 initialization to fix a race condition.
5098 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

5122 set the multi_byte flag correctly in symbols. This is wrong.
5123 intern_obbary_soft and msymbolize should take an extra parameter.
5124 Also, weird multibyte symbols don't print correctly.
5125 The weird symbol syntax is also a bit bogus (emacs doesn't quite
